AmpliPhi Biosciences Corporation

Condensed Notes to Consolidated Financial Statements

March 31, 2016
(Unaudited)

1. Organization and Description of the Business

AmpliPhi Biosciences Corporation (the “Company”) was incorporated in the state of Washington in 1989 under the name Targeted Genetics Corporation. In February 2011, Targeted Genetics Corporation changed its name to AmpliPhi Biosciences Corporation. The Company is dedicated to developing novel antibacterial therapies called bacteriophage (phage). Phages are naturally occurring viruses that preferentially target and kill their bacterial targets.

2. Liquidity

The Company has prepared these consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. However, the Company has incurred net losses since its inception, has negative operating cash flows and has an accumulated deficit of $365.6 million as of March 31, 2016, $50.1 million of which has been accumulated since January of 2011, when the Company began its focus on bacteriophage development. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern.

As of March 31, 2016, the Company had cash and cash equivalents of $6.2 million. Management believes that our existing resources will be sufficient to fund our planned operations into the third quarter of 2016.

The Company’s ability to raise additional funds will depend, in part, on the status of its product development activities and other business operations, as well as factors related to financial, economic, and market conditions, many of which are beyond its control. The Company cannot be certain that sufficient funds will be available to it when required or on acceptable terms, if at all. If adequate funds are not available on a timely basis or on acceptable terms, the Company may be required to significantly reduce or refocus its operations or to obtain funds through additional arrangements that may require the Company to relinquish rights to certain of its products, technologies or potential markets, any of which could delay or require that it curtail or eliminate some or all of its development programs or otherwise have a material adverse effect on the business, financial condition and results of operations.

3. Significant Accounting Policies

The Company’s significant accounting policies are described in Note 3 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Since the date of those financial statements, there have been no material changes to the Company’s significant accounting policies. The interim consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries Biocontrol Limited, Ampliphi d.o.o., and AmpliPhi Australia Pty Ltd. All significant intercompany accounts and transactions have been eliminated.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company should be read in conjunction with the audited financial statements and notes thereto as of and for the year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission (SEC). The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial statements and in accordance with the instructions to Form 10-Q. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (ASC) and Accounting Standards Update (ASU) of the Financial Accounting Standards Board (FASB).

In the opinion of management, the accompanying financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of March 31, 2016 and the results of its operations for the three months ended March 31, 2016 and 2015. Interim results are not necessarily indicative of results for the full year or any future period.

Reverse Stock Split

On August 3, 2015, the Company filed Articles of Amendment to Amended and Restated Articles of Incorporation with the Secretary of State of the State of Washington that effected a 1-for-50 (1:50) reverse stock split of its common stock, par value $0.01 per share, effective August 7, 2015. On August 3, 2015, the Company increased its authorized common stock, from 445,000,000 to 670,000,000 shares. The par value of its common stock was unchanged at $0.01 per share, post-split. All warrant, stock option, and per share information in the consolidated financial statements gives retroactive effect to the 1-for-50 reverse stock split that was effected on August 7, 2015.

Use of Estimates

Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of the financial statements if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. In preparing these financial statements, management used significant estimates in the following areas, among others: the determination of the fair value of stock-based awards, the fair value of liability-classified preferred stock derivatives, the fair value of liability-classified warrants, the valuation of long-lived assets, including in-process research and development (IPR&D), patents and goodwill, accrued expenses and the recoverability of the Company's net deferred tax assets and related valuation allowance.

Warrant and Preferred Shares Conversion Feature Liability

The Company accounts for both warrants with anti-dilution adjustment provisions and other features and preferred share features with anti-dilution adjustment provisions under the applicable accounting guidance which requires the warrant and the preferred share features to be recorded as liabilities and adjusted to fair value at each reporting period.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a single source of revenue guidance for companies in all industries. The new standard provides guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers, unless the contracts are within the scope of other accounting standards. It also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets. This guidance, as amended, must be adopted using either a full retrospective approach for all periods presented or a modified retrospective approach and will be effective for fiscal years beginning after December 15, 2017. The Company has not yet evaluated the potential impact of adopting the guidance on its consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The ASU is part of a simplification initiative aimed at reducing complexity in accounting standards. Current GAAP requires the deferred taxes for each jurisdiction (or tax-paying component of a jurisdiction) to be presented as a net current asset or liability and net noncurrent asset or liability. To simplify presentation, the new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The standard is effective for public entities for annual reporting periods beginning after December 15, 2016, and interim periods therein. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's results of operations or liquidity.

In February 2015, the FASB issued ASU 2016-02, Leases (Topic 842), which amends the FASB Accounting Standards Codification and creates Topic 842, "Leases." The new topic supersedes Topic 840, "Leases," and increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosures of key information about leasing arrangements. The guidance is effective for reporting periods beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method. The Company has not yet evaluated the potential impact of adopting the guidance on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which defines management's responsibility to assess an entity's ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. The pronouncement is effective for annual reporting periods ending after December 15, 2016 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification (“ASC”) Topic 718, Compensation – Stock Compensation. ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The Company has not yet evaluated the potential impact of adopting the guidance on its consolidated financial statements.

4. Fair Value of Financial Assets and Liabilities — Derivative Instruments

ASC Topic 820, Fair Value Measurement (ASC 820), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820 establishes a three-tier fair value hierarchy that distinguishes among the following:

| · | Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.
| · | Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.
| · | Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Items measured at fair value on a recurring basis include common stock warrants and embedded derivatives related to the Company’s redeemable convertible preferred stock. During the periods presented, the Company has not changed the manner in which it values liabilities that are measured at fair value using Level 3 inputs. The following fair value hierarchy table presents information about each major category of the Company's financial liabilities measured at fair value on a recurring basis:

|  | Quoted Prices in |  |  |  |  |  |  |  |  |  |
|  | Active Markets |  |  | Significant Other |  |  | Significant |  |  |  |
|  | for Identical |  |  | Observable Inputs |  |  | Unobservable |  |  |  |
|  | Items (Level 1) |  |  | (Level 2) |  |  | Inputs (Level 3) |  |  | Total |

Total liabilities |  | $ | - |  |  | $ | - |  |  | $ | 1,499,000 |  |  | $ | 1,499,000 |

There were no transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy for the three months ended March 31, 2016 and the year ended December 31, 2015.

The following table sets forth a summary of changes in the fair value of the Company's Series B redeemable convertible preferred stock derivative and warrant liability, which represents a recurring measurement that is classified within Level 3 of the fair value hierarchy, wherein fair value is estimated using significant unobservable inputs:

|  |  |  |  | Series B Preferred |
|  | Warrant |  |  | Stock Derivative |
|  | Liability |  |  | Liability |
Balance, December 31, 2015 |  | $ | 6,000 |  |  | $ | 1,493,000 |
Changes in estimated fair value |  |  | (4,000 | ) |  |  | (1,402,000 | )
Balance, March 31, 2016 |  | $ | 2,000 |  |  | $ | 91,000 |

| 9

The fair value of the warrants on the date of issuance and on each re-measurement date for warrants classified as liabilities is estimated using the Monte Carlo valuation model. For this liability, the Company develops its own assumptions that do not have observable inputs or available market data to support the fair value. This method of valuation involves using inputs such as the fair value of the Company’s common stock, stock price volatility, the contractual term of the warrants, risk–free interest rates and dividend yields. Due to the nature of these inputs, the valuation of the warrants is considered a Level 3 measurement. The following assumptions were used at March 31, 2016 and December 31, 2015:

|  | March 31, 2016 |  |  | December 31, 2015 |
|  | Series (1) |  |  | Series (1) |
|  | 2011 |  |  | 2011 |

(1) See Note 7 – Warrants below for further description of the respective series of warrants.

The warrant liability is recorded on the accompanying consolidated balance sheets and is marked-to-market at each reporting period, with the change in fair value recorded as a component of change in fair value of warrant liability on the Company’s statements of operations.

The fair value of the Series B preferred stock derivative liability on each measurement date is estimated using the Monte Carlo valuation model. For this liability, the Company develops its own assumptions that do not have observable inputs or available market data to support the fair value. This method of valuation involves using inputs such as the fair value of the Company’s common stock, stock price volatility, the expected term of the Series B preferred stock, risk–free interest rates and dividend yields. Due to the nature of these inputs, the valuation of the Series B preferred conversion liability is considered a Level 3 measurement. The following assumptions were used at March 31, 2016 and December 31, 2015:

|  | March 31, |  |  | December 31, |
|  | 2016 |  |  | 2015 |
Volatility |  |  | 108 | % |  |  | 108 to 117 | %
Expected term (years), weighted average |  |  | 0.04 to 0.75 |  |  |  | 0.50 to 2.50 |
Risk-free interest rate |  |  | 0.18 to 0.49 | % |  |  | 0.49 to 1.19 | %
Dividend yield |  |  | 0.00 | % |  |  | 0.00 | %
Exercise price |  | $ | 7.00 |  |  | $ | 7.00 |
Common stock closing price |  | $ | 3.94 |  |  | $ | 3.98 |

The Series B preferred stock derivative liability is recorded on the accompanying consolidated balance sheet and is marked-to-market each reporting period, with the change in fair value recorded as a component of change in fair value of Series B preferred stock derivative liability on the Company’s statements of operations.

6. Redeemable Convertible Preferred Stock

On June 13, 2013, the Company’s Board of Directors approved a resolution designating 9,357,935 shares of Preferred Stock as Series B redeemable convertible preferred stock (Series B) with an initial stated value of $1.40 and par value of $0.01. As of March 31, 2016, each Series B share was convertible into 0.20 shares of common stock and was entitled to the number of votes equal to the number of shares of common stock into which such Series B share could be converted. The Series B shares were convertible into common stock by the holder of the shares at any time. The Series B shares were subject to automatic conversion into common stock upon the election of the holders of at least two-thirds of the outstanding Series B shares. In addition, pursuant to the Company’s Articles of Incorporation, the Series B shares were automatically convertible into common stock upon the occurrence of an underwritten initial public offering by the Company that satisfied certain conditions.

Holders of the Series B shares were entitled to receive cumulative, cash dividends at the rate of 10% of the Series B stated value. Such dividends accrue from day-to-day commencing on the original issue date, whether or not earned or declared by the Board of Directors, and were compounded annually. No dividends had been declared or paid on the Series B shares through March 31, 2016.

The Series B shares were redeemable by the Company at any time on or after June 26, 2018, upon the election of the holders of at least two-thirds of the outstanding Series B shares for an amount equal to the original issue price per share plus any accrued and unpaid dividends.

Holders of the Series B shares were entitled to a liquidation preference in an amount equal to the Series B stated value of $1.40 per share plus all accrued and unpaid dividends in the event of a liquidation, dissolution, or winding-up of the Company, or in the event of a merger or acquisition of the Company.

In connection with the private placement of Series B shares, the Company recorded a liability for an embedded derivative that required bifurcation under the applicable accounting guidance. The embedded derivative includes a redemption feature, multiple dividend features, as well as multiple conversion features with specified anti-dilution adjustments for certain financing transactions involving the issuance of securities at a price below a minimum non-diluting issuance price of $7.00 per share.

The Company re-measured the fair value of the derivative feature and recorded a gain of $1,402,000 for the three months ended March 31, 2016 to adjust the liability associated with the conversion feature to its estimated fair value of $91,000 as of March 31, 2016. For the three months ended March 31, 2015, the Company recorded a loss of $7,105,000 to adjust the liability associated with the conversion feature to its estimated fair value of $19,425,000 as of March 31, 2015.

At March 31, 2016, the Company accreted $1,402,000 from additional paid-in capital to Series B redeemable convertible preferred stock to adjust the redemption value of the Series B to actual at that date.

The March 31, 2016 balance sheet reflects dividends payable of $368,000 to former holders of preferred stock, which are classified as current liabilities.

On April 8, 2016, the Series B redeemable convertible preferred stock was automatically converted into common stock pursuant to the election of the holders of over two-thirds of the then-outstanding Series B shares. See Note 13 – Subsequent Events.

7. Warrants

On January 4, 2016, the Company entered into an Asset Purchase Agreement with Novolytics Limited (the “Purchase Agreement”), to purchase certain preclinical materials and intangible assets, including patent rights, from Novolytics, an unrelated third party. In consideration for the assets acquired, the Company paid cash consideration of approximately $205,000 and issued warrants to purchase an aggregate of 170,000 shares of the Company’s common stock. The warrants have an exercise price of $12.00 per share and contain certain registration rights. The fair value of the warrants issued was $204,000, based on a Monte Carlo valuation model and are classified as equity within the consolidated balance sheet. The Company expensed the total value provided for the acquired assets of $409,000 as in-process research and development as of the acquisition date given there was no alternative future use of the acquired assets due to the early stage nature of the technology and pre-clinical materials.

The following table provides a summary of warrants outstanding, issued or exercised for the three months ended March 31, 2016. Also included is the average exercise price per share and the aggregate proceeds to the Company if exercised as of March 31, 2016.

8. Stockholders’ Equity

On March 16, 2015, the Company issued and sold 1,575,758 shares of common stock in a private placement at a price of $8.25 per share, for aggregate proceeds of $13.0 million. In conjunction with this private placement, the Company issued warrants to purchase an aggregate of 393,939 shares of common stock at an exercise price of $10.75 per share to the purchasers of the common stock. The Company paid $833,000 in fees to its placement agents, along with the issuance of warrants to purchase an aggregate of 94,545 shares of common stock at an exercise price of $10.75 per share. The Company valued these warrants as liability instruments and recorded a liability of $4,210,000 as of March 16, 2015. In the first quarter of 2015, the Company recorded $213,000 of other expenses representing the portion of the initial warrant value of the placement agent warrants related to the initial fair value of the warrants issued to the purchasers of the common stock. The remainder of the initial fair value of the warrants of $3,996,000 was treated as a reduction of additional paid-in-capital. In addition, $218,000 of the fees paid to its placement agent were expensed as other expenses in the three months ended March 31, 2015 as they also represented issuance costs related to the initial fair value of the warrants issued to the purchasers of the common stock.

9. Stock-Based Compensation

The Company’s 2013 Stock Incentive Plan (Stock Incentive Plan) provides for the issuance of incentive awards in the form of non-qualified and incentive stock options, stock appreciation rights, stock grants and restricted stock units. The awards may be granted by the Company’s Board of Directors to its employees, directors and officers and to consultants, agents, advisors and independent contractors who provide services to the Company or to a subsidiary of the Company. The exercise price for stock options must not be less than the fair market value of the underlying shares on the date of grant. Stock options expire no later than ten years from the date of grant and generally vest and typically become exercisable over a four-year period following the date of grant. Upon the exercise of stock options, the Company issues the resulting shares from shares reserved for issuance under the Stock Incentive Plan.

The Company accounts for stock options and restricted stock units related to its stock incentive plans under the provisions of ASC 718, which requires the recognition of the fair value of stock-based compensation. The fair value of stock options was estimated using a Black-Scholes option valuation model. This model requires the input of subjective assumptions in implementing ASC 718, including expected dividend, expected life, expected volatility and forfeiture rate of each award, as well as the prevailing risk-free interest rate and the fair value of the underlying common stock on the date of grant. The fair value of equity-based awards is amortized over the vesting period of the award, and the Company has elected to use the straight-line method of amortization. The assumptions used in the Black-Scholes option valuation model for the three months ended March 31, 2016 are set forth below.

| 12

| · | Expected Dividend: The Company does not anticipate paying any dividends on its common stock.
| · | Expected Life: The expected life represents the period that the Company expects its stock-based awards to be outstanding. The Company’s expected life assumption was based on the simplified method set forth in the SEC Staff Accounting Bulletin 110. The Company’s estimation of the expected life for stock options granted to parties other than employees or directors is the contractual term of the option award.
| · | Expected Volatility: Expected volatility is the measure by which the Company’s stock price is expected to fluctuate during the expected term of an option. The Company’s expected volatility represents the weighted average historical volatility of the shares of its common stock.
| · | Risk-Free Interest Rate: The Company bases the risk-free interest rate used on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. Where the expected term of its stock-based awards does not correspond with the terms for which interest rates are quoted, the Company performs a straight-line interpolation to determine the rate from the available term maturities.
| · | Forfeiture Rate: The Company applies an estimated forfeiture rate that is derived from historical forfeited shares. If the actual number of forfeitures differs from our estimates, the Company may record additional adjustments to compensation expense in future periods.

The weighted-average assumptions used in the Black-Scholes option pricing model to determine the fair value of the stock option grants were as follows:

|  | March 31, |
|  | 2016 |
Risk-free interest rate |  |  | 1.58 to 1.63 | %
Expected volatility |  |  | 113.0 | %
Expected term (in years) |  |  | 6.0 |
Expected dividend yield |  |  | 0.0 | %

Stock-based compensation expense is reduced by an estimated forfeiture rate derived from historical employee termination behavior. If the actual number of forfeitures differs from the Company’s estimates, the Company may record adjustments to increase or decrease compensation expense in future periods.

The estimated grant-date fair value of the Company’s stock-based awards is amortized ratably over the awards’ service periods. Stock-based compensation expense recognized was as follows:

|  | Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
|  | (Unaudited) |  |  | (Unaudited) |
Research and development |  | $ | 26,000 |  |  | $ | 29,000 |
General and administrative |  |  | 790,000 |  |  |  | 23,000 |
Total stock-based compensation |  | $ | 816,000 |  |  | $ | 52,000 |

The following table summarizes stock option activity for the three months ended March 31, 2016:

|  |  |  |  | Options Outstanding |

As of March 31, 2016, the Company had a liability of $54,000 recorded for amounts due to Intrexon. See Note 13 – Subsequent Events.

In April 2013, the Company entered into a collaboration agreement with the University of Leicester to develop a phage therapy that targets and kills all toxin types of C. difficile. In August 2013, the Company entered into a collaboration agreement with both the University of Leicester and the University of Glasgow to carry out certain animal model development work. Under these agreements, which are referred to collectively as the Leicester Development Agreements, the Company provides payments to the University of Leicester to carry out in vitro and to the University of Glasgow to carry out animal model development work on the University of Leicester’s development of a bacteriophage therapeutic to resolve C. difficile infections. The Company licensed related patents, materials and know-how from the University of Leicester. Under the Leicester Development Agreements, the University of Leicester will provide the bacteriophage and act as overall project coordinator for the development work. All rights, title and interest to any intellectual property developed under the Leicester Development Agreements belong to the Company. Under the Leicester License Agreement, the Company has exclusive rights to certain background intellectual property of the University of Leicester, for which it will pay the University of Leicester royalties based on product sales and make certain milestone payments based on product development. In November 2015, the Company renewed this collaboration, effective as of November 12, 2015. This agreement expires November 12, 2018. During the three months ended March 31, 2016, the Company recorded $43,000 in expenses to the University of Leicester under the Leicester Development Agreements, with cash payments totaling $46,000. During the three months ended March 31, 2015, the Company recorded $35,000 in expenses to the University of Leicester under the Leicester Development Agreements, with cash payments totaling $50,000.

In September 2015, the Company entered into a non-exclusive patent license agreement with Takara Bio Inc. (the Takara Agreement). Under this agreement Takara licensed certain patents from the Company related to AAV1 Vector gene delivery systems, for which the Company is an exclusive licensor with the University of Pennsylvania. The Company received a $40,000 non-refundable, up-front licensing payment and is entitled to receive royalties from Takara of 12.0% of net license product sales and 6.0% of service revenues associated with the licensed products. The agreement calls for minimum annual royalties of $15,000 commencing on February 28, 2016. In addition, the Takara Agreement provides milestone fees to the Company of $30,000 of the first $1,000,000 of licensed product revenues by Takara and an additional $40,000 when cumulative net sales of the licensed product by Takara exceed $2,000,000. During the three months ended March 31, 2016, the Company recognized revenue of $4,000 under the Takara Agreement.

11. Severance Charge

In September of 2014 and 2015 two executives separated from the Company. The Company recorded severance expenses in the respective periods and accrued severance related to the cash portion due over time.

The severance accrual as of December 31, 2015 and March 31, 2016 is as follows:

Accrued severance, December 31, 2015 |  | $ | 308,000 |
Cash payments in 2016 |  |  | (170,000 | )
Accrued severance, March 31, 2016 |  | $ | 138,000 |

12. Legal Proceedings

The Company determines whether it should accrue an estimated loss for a contingency in a particular legal proceeding by assessing whether a loss is deemed probable and whether the amount can be reasonably estimated. Claim estimates that are probable and can be reasonably estimated are reflected as liabilities. Legal proceedings are inherently unpredictable and the matters in which the Company may be involved often will present complex legal and factual issues. Because of the uncertainties related to the Company’s pending litigation, investigations, inquiries or claims, management is currently unable to predict the ultimate outcome of any litigation, investigation, inquiry or claim, determine whether a liability has been incurred, or make an estimate regarding the possible loss or range of loss that could result from an unfavorable outcome. It is reasonably possible that some of the matters which may be asserted could be decided unfavorably to the Company. An adverse ruling or outcome in any lawsuit involving the Company could materially affect its business, liquidity, consolidated financial position or results of operations. In view of the unpredictable nature of such matters, the Company cannot provide any assurances regarding the outcome of any litigation, investigation, inquiry or claim to which it is a party of the impact on the Company of an adverse ruling on such matters.

On April 14, 2016, a complaint was filed against the Company and certain of its board members. See Note 13 – Subsequent Events.

13. Subsequent Events

Series B Convertible Preferred Stock Conversion

On April 8, 2016, certain holders (the “Holders”) of over two-thirds of the Company’s then-outstanding shares of Series B redeemable convertible preferred stock (“Series B Preferred”) elected to automatically convert all outstanding shares of Series B Preferred into shares of Common Stock in accordance with Section 4.4.4(b)(ii) of the Company’s Amended and Restated Articles of Incorporation (the “Conversion”). As a result of the Conversion, the 7,527,853 shares of Series B Preferred outstanding as of immediately prior to the Conversion have been converted into an aggregate of 1,505,560 shares of Common Stock.

On April 8, 2016, the Company entered into a Common Stock Issuance Agreement (the “Agreement”) with the Holders pursuant to which the Company agreed to issue the Holders an aggregate of 853,465 shares of the Company’s Common Stock (the “Shares”). Pursuant to the Agreement, the Company and the Holders also agreed to amend the Common Stock warrants issued to the Holders pursuant to that certain Subscription Agreement, dated June 25, 2013, in order to reduce the exercise price of such warrants from $7.00 per share to $4.05 per share and extend the expiration date thereof from June 26, 2018 to March 31, 2021 (the “Warrant Amendments”). As consideration for the Shares and the Warrant Amendments, the Holders waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the Conversion in respect of accrued dividends on their former shares of Series B Preferred. The Holders also waived their registration rights with respect to certain future registration statements that may be filed, and certain future public offerings that may be conducted, by the Company.

| 15

Pursuant to the Agreement, if in the future the Company conducts one or more bona fide equity financings in which it sells shares of Common Stock or Preferred Stock at a price less than $4.05 per share (each, a “dilutive financing”), the Company will be required to issue to the Holders additional shares of Common Stock based on a specified formula. The obligation to issue additional shares in the event of any such dilutive financing (i) only applies to the lowest priced financing conducted after the date of the Agreement, (ii) is subject to limitations under applicable NYSE MKT rules relating to the issuance of additional shares in a private placement at a price less than the greater of book or market value and (iii) will expire at such time the Company has raised $10.0 million in gross proceeds from the sale of Common Stock and/or Preferred Stock in a bona fide financing or financings or June 30, 2018, whichever occurs first. The Company has agreed to seek shareholder approval of the issuance of up to 1,037,053 shares of Common Stock to the Holders in the future as required by the Agreement in connection with one or more dilutive financings. To the extent the Company is not permitted by applicable NYSE MKT rules to issue any additional shares of Common Stock that would otherwise be required to be issued pursuant to the terms of the Agreement as a result of a dilutive financing, the Company has agreed to pay the Holders a cash payment equal to the difference between the price per share in such dilutive financing and $4.05 for each share issued to the Holders pursuant to the Conversion.

Litigation

On April 14, 2016, NRM VII Holdings I, LLC (“NRM”), an affiliate of Third Security, LLC (“Third Security”), filed a complaint against the Company and certain members of the Company’s Board in the Superior Court of California, County of San Diego. Third Security is one of the principal shareholders of the Company. The complaint alleges that the Company breached the implied covenant of good faith by entering into a scheme to force NRM to convert its Series B Shares into Common Shares. The complaint further alleges that the members of the Board who were named as defendants breached their fiduciary duty of good faith owed to NRM, as one of the Company’s shareholders, by participating in this transaction. The complaint seeks unspecified monetary damages and other relief. The Company plans to vigorously defend against the claims advanced.

Collaboration Agreement

On April 13, 2016, the Company provided written notice to Intrexon Corporation of its election to voluntarily terminate its ECC Agreement dated March 29, 2013 (see Note 10). The effective date of the termination will be 90 days following delivery of the termination notice. The Company will not incur any early termination penalties as a result of the termination of the ECC Agreement.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q, and the audited financial statements and notes thereto as of and for the year ended December 31, 2015 included in our Annual Report on Form 10-K filed with the SEC.

Statements contained in this report that are not statements of historical fact are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Such forward-looking statements include, without limitation, statements concerning product development plans, the use of bacteriophages to kill bacterial pathogens, having resources sufficient to fund our operations into the third quarter of 2016, future revenue sources, selling and marketing expenses, general and administrative expenses, clinical trial and other research and development expenses, capital resources, capital expenditures, tax credits and carry-forwards, and additional financings and litigation-related matters. Words such as “believe,” “anticipate,” “plan,” “expect,” “intend,” “will,” “goal,” “potential” and similar expressions are intended to identify forward-looking statements, though not all forward-looking statements necessarily contain these identifying words. These statements are subject to risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth below under Part II, Item 1A, “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. These forward-looking statements speak only as of the date on which they were made, and we undertake no obligation to update any forward-looking statements.

Overview

We are a biotechnology company focused on the discovery, development and commercialization of novel phage therapeutics. Phage therapeutics use bacteriophages, a family of viruses, to kill pathogenic bacteria. Phages have powerful and highly selective mechanisms of action that permit them to target and kill specific bacteria. We believe that phages represent a promising means to treat bacterial infections, especially those that have developed resistance to current therapies including the so-called multi-drug-resistant or “superbug” strains of bacteria.

Our goal is to be the leading developer of phage therapeutics. We are combining our expertise in the manufacture of drug-quality bacteriophages and our proprietary approach and expertise in identifying, characterizing and developing naturally occurring bacteriophages with that of our collaboration partners in bacteriophage biology, synthetic biology and manufacturing, to develop second-generation bacteriophage products.

Our lead product candidate is AB-SA01 for the treatment of S. aureus infections, including methicillin-resistant S. aureus, or MRSA. We also have AB-PA01 for the treatment of P. aeruginosa infections in development, and AB-CD01 for the treatment of C. difficile infections in preclinical development.

We have generally incurred net losses since our inception and our operations to date have been primarily limited to research and development and raising capital. We have raised approximately $43.6 million in capital to support our operations since the shift in our focus to novel phage therapeutics in February 2011.

To date, we have not generated any product revenue and have primarily financed our operations through the sale and issuance of our equity securities and convertible notes. As of March 31, 2016, we had a cumulative deficit of $365.6 million. We anticipate that a substantial portion of our capital resources and efforts in the foreseeable future will be focused on completing the development and obtaining regulatory approval of our product candidates.

We currently expect to use our existing cash and cash equivalents for the continued research and development of our product candidates and for working capital and other general corporate purposes.

We expect our research and development expenses to increase for the foreseeable future as we continue development of our product candidates. We also expect to incur additional expenses associated with operating as a public company. As a result, we expect to continue to incur significant and increasing operating losses at least for the next several years. We do not expect to generate product revenue unless and until we successfully complete development and obtain marketing approval for at least one of our product candidates.

We may also use a portion of our existing cash and cash equivalents for the potential acquisition of, or investment in, product candidates, technologies, formulations or companies that complement our business, although we have no current understandings, commitments or agreements to do so. Our existing cash and cash equivalents will not be sufficient to enable us to complete all necessary development of any potential product candidates. Accordingly, we will be required to obtain further funding through one or more other public or private equity offerings, debt financings, collaboration or licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs.

Recent Events

Series B Redeemable Convertible Preferred Stock Conversion

On April 8, 2016, certain holders (the “Holders”) of over two-thirds of our then-outstanding shares of Series B redeemable convertible preferred stock (“Series B Preferred”) elected to automatically convert all outstanding shares of Series B Preferred into shares of Common Stock in accordance with Section 4.4.4(b)(ii) of our Amended and Restated Articles of Incorporation (the “Conversion”). As a result of the Conversion, the 7,527,853 shares of Series B Preferred outstanding as of immediately prior to the Conversion have been converted into an aggregate of 1,505,560 shares of Common Stock.

On April 8, 2016, we entered into a Common Stock Issuance Agreement (the “Agreement”) with the Holders pursuant to which we agreed to issue the Holders an aggregate of 853,465 shares of our Common Stock (the “Shares”). Pursuant to the Agreement, the Company and the Holders also agreed to amend the Common Stock warrants issued to the Holders pursuant to that certain Subscription Agreement, dated June 25, 2013, in order to reduce the exercise price of such warrants from $7.00 per share to $4.05 per share and extend the expiration date thereof from June 26, 2018 to March 31, 2021 (the “Warrant Amendments”). As consideration for the Shares and the Warrant Amendments, the Holders waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the Conversion in respect of accrued dividends on their former shares of Series B Preferred. The Holders also waived their registration rights with respect to certain future registration statements that may be filed, and certain future public offerings that may be conducted, by us.

Pursuant to the Agreement, if in the future we conduct one or more bona fide equity financings in which it sell shares of Common Stock or Preferred Stock at a price less than $4.05 per share (each, a “dilutive financing”), we will be required to issue to the Holders additional shares of Common Stock based on a specified formula. The obligation to issue additional shares in the event of any such dilutive financing (i) only applies to the lowest priced financing conducted after the date of the Agreement, (ii) is subject to limitations under applicable NYSE MKT rules relating to the issuance of additional shares in a private placement at a price less than the greater of book or market value and (iii) will expire at such time we have raised $10.0 million in gross proceeds from the sale of Common Stock and/or Preferred stock in a bona fide financing or financings or June 30, 2018, whichever occurs first.

To the extent we are not permitted by applicable NYSE MKT rules to issue any additional shares of Common Stock that would otherwise be required to be issued pursuant to the terms of the Agreement as a result of a dilutive financing, we have agreed to pay the Holders a cash payment equal to the difference between the price per share in such dilutive financing and $4.05 for each share issued to the Holders pursuant to the Conversion.

Collaboration Agreement

On April 13, 2016, we provided written notice to Intrexon Corporation (“Intrexon”) of our election to voluntarily terminate that certain Exclusive Channel Collaboration Agreement, dated as of March 29, 2013, by and between us and Intrexon (the “ECC Agreement”). The effective date of termination (the “Termination Date”) will be 90 days following delivery of the termination notice. We will not incur any early termination penalties as a result of the termination of the ECC Agreement.

The ECC Agreement is directed towards the research, development and commercialization of new bacteriophage-based therapies for the treatment of bacterial infections caused by P. aeruginosa and C. difficile. A summary of the material terms of the ECC Agreement is contained in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 30, 2016, under Item 1. Business—Exclusive Channel Collaboration with Intrexon, and is incorporated herein by reference.

Results of Operations

Comparison of three months ended March 31, 2016 and 2015

Revenue

For each of the quarters ended March 31, 2016 and 2015, we recognized $0.1 million in revenue primarily related to sublicensing agreements from our former gene therapy program.

Research and Development Expenses

Research and development expenses for the quarter ended March 31, 2016 totaled $2.0 million compared to $1.0 million incurred in the same period of 2015. This increase of $1.0 million was primarily related to higher compensation costs of $0.2 million, $0.1 million of professional recruiting fees, and $0.4 million for the expense recorded related to the assets acquired from Novolytics.

We anticipate that research and development spending in future periods will continue to increase as we initiate non-clinical research studies, hire additional research and development staff, advance our clinical trials, and continue our discovery efforts.

| 18

General and Administrative Expenses

General and administrative expenses for the quarter ended March 31, 2016 were $2.6 million compared to $1.4 million for the same period of 2015. The $1.2 million increase was primarily attributable to $0.9 million of compensation, including $0.8 million of non-cash stock-based compensation, related to two new executives, and $0.3 million for professional fees for legal, accounting and recruitment.

Other Income (Expense)

We recorded a gain of $4,000 for the quarter ended March 31, 2016 related to the change in fair value of our warrant liability, which was primarily attributable to a decrease in the value of our common stock price during the period.

We recorded a gain of $1.4 million for the quarter ended March 31, 2016 related to the change in fair value of our Series B preferred stock derivative liability. This gain was primarily attributable to a decrease in the estimated term of the derivative liability associated with the Series B preferred stock at March 31, 2016.

We will continue to adjust the liability related to our outstanding Series 2011 warrants to fair value until the earlier of exercise or expiration of the warrants or until terms of the warrants no longer require them to be accounted for as liability instruments. We continued to adjust the liability related to our Series B preferred stock derivative feature until the conversion of our Series B preferred stock into common stock in April 2016.

We also recorded expenses of $0.4 million for the three months ended March 31, 2015 consisting of placement agent costs from our March 2015 private placement of common stock, which related to placement agent fees and the initial fair value of warrants issued to the placement agents. We had no comparable costs during the three months ended March 31, 2016.

Liquidity and Capital Resources

We have incurred net losses since inception through March 31, 2016 of $365.6 million, of which $315.5 million was incurred as a result of our prior focus on gene therapy in fiscal years 2010 and earlier. We have not generated any product revenues and do not expect to generate revenue from product candidates in the near term.

We had cash and cash equivalents of $6.2 million and $9.4 million at March 31, 2016 and December 31, 2015, respectively.

Net cash used in operating activities for the three months ended March 31, 2016 was $3.1 million, as compared to $2.3 million for the three months ended March 31, 2015. Net loss recorded during the three months ended March 31, 2016 was $3.1 million, inclusive of a $1.4 million non-cash gain on derivative liability. Net loss recorded during the three months ended March 31, 2015 was $14.5 million, inclusive of a $11.8 million non-cash loss on derivative liability. The net increase in cash used in operating activities of $0.8 million, in addition to the effect of the non-cash derivative liability effects noted above, are primarily related to an increase in research and development efforts, payroll and non-cash stock based compensation, as well as an increase in professional services.

Net cash used in investing activities was $0.1 million and $0.0 million for three months ended March 31, 2016 and March 31, 2015, respectively. Net cash used in investing activities for the three months ended March 31, 2016 was primarily attributable to purchases of property and equipment.

Cash provided by financing activities for the three months ended March 31, 2015 was comprised of the gross proceeds of $13.0 million from the March 2015 private placement of common stock and warrants to purchase common stock, less commissions and other cash expenses related to the issuance of approximately $0.6 million. There were no financing activities for the three months ended March 31, 2016.

We will need to raise additional capital or incur indebtedness to continue to fund our future operations. Our future funding requirements will depend on many factors, including:

| · | the costs and timing of our research and development activities;
| · | the progress and cost of our clinical trials and other research and development activities;
| · | the cost and timing of securing manufacturing capabilities for our clinical product candidates and commercial products, if any;
| · | the terms and timing of any collaborative, licensing, acquisition or other arrangements that we may establish;
| · | the costs and timing of seeking regulatory approvals;
| · | the costs of filing, prosecuting and enforcing any patent applications, claims, patents and other intellectual property rights; and
| · | the costs of lawsuits involving us or our product candidates.

We may seek to raise capital through a variety of sources, including:

| · | the public equity market;
| · | private equity financings;
| · | collaborative arrangements;

| 19

| · | licensing arrangements; and/or
| · | public or private debt.

We believe our existing resources are sufficient to fund our planned operations into the third quarter of 2016. This estimate is based on our current product development calendar, projected staffing expenses, working capital requirements, and capital expenditure plans.

Our ability to raise additional funds will depend on our clinical and regulatory events, our ability to identify promising in-licensing opportunities and factors related to financial, economic and market conditions, many of which are beyond our control. We cannot be certain that sufficient funds will be available to us when required or on satisfactory terms. If adequate funds are not available, we may be required to significantly reduce or refocus our operations or to obtain funds through arrangements that may require us to relinquish rights to certain of our products, technologies or potential markets, any of which could delay or require that we curtail our development programs or otherwise have a material adverse effect on our business, financial condition and results of operations. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such securities would result in ownership dilution to our existing stockholders.

If we are unable to secure additional financing on a timely basis or on terms favorable to us, we may be required to significantly reduce or refocus our operations or to obtain funds through additional arrangements that may require us to relinquish rights to certain of our products, technologies or potential markets, any of which could delay or require that we curtail or eliminate some or all of our development programs or otherwise have a material adverse effect on our business, financial condition and results of operations. This uncertainty around our ability to secure additional financing creates substantial doubt about our ability to continue as a going concern.

Contractual Obligations and Commitments

As of March 31, 2016, there have been no material changes, outside of the ordinary course of business, in our outstanding contractual obligations from those disclosed within “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, as contained in our Annual Report on Form 10-K for the year ended December 31, 2015.

Off-Balance Sheet Arrangements

As of March 31, 2016, we did not have off-balance sheet arrangements.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective disclosure controls system, misstatements due to error or fraud may occur and not be detected.

Based on this evaluation, our Chief Executive Officer and Chief Financial Officer, have concluded that our disclosure controls and procedures were not effective at the reasonable assurance level during the period covered by this report.

Changes in Internal Control Over Financial Reporting

An evaluation was also performed under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, other than the following:

| · | the appointment of an experienced Chief Financial Officer in January 2016 with significant experience in public company reporting and complex transactions; and
| · | the engagement of consultants with experience in the review of unique and complex accounting topics, who consulted with management on complex transactions and reporting.

Remediation of Material Weakness

We continue to review, document and test our internal control over financial reporting. We also continue to take steps to remediate certain identified deficiencies in our internal control over financial reporting as of December 31, 2015 in the area of complex and non-routine transactions. Although efforts remain in process, steps taken during the last fiscal quarter that resulted in improvements to our internal control over financial reporting included the following:

| · | commenced designing additional training programs for relevant personnel and development of specific review procedures regarding the review of complex and non-routine transactions; and
| · | implemented standardized financial control and reporting processes.

The remediation actions will be monitored by the Audit Committee of our Board of Directors.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

On April 14, 2016, NRM VII Holdings I, LLC (“NRM”), an affiliate of Third Security, LLC (“Third Security”), filed a complaint against us and certain members of our Board in the Superior Court of California, County of San Diego. Third Security is one of our principal shareholders. The complaint alleges that we breached the implied covenant of good faith by entering into a scheme to force NRM to convert its shares of Series B redeemable convertible preferred stock into shares of our common stock. The complaint further alleges that the members of the Board who were named as defendants breached their fiduciary duty of good faith owed to NRM, as one of our shareholders, by participating in this transaction. The complaint seeks unspecified monetary damages and other relief. We plan to vigorously defend against the claims advanced.

Claim estimates that are probable and can be reasonably estimated are reflected as liabilities. Because of the uncertainties related to our pending litigation, investigations, inquiries or claims, management is currently unable to predict the ultimate outcome of any litigation, investigation, inquiry or claim, determine whether a liability has been incurred, or make an estimate regarding the possible loss or range of loss that could result from an unfavorable outcome. It is reasonably possible that some of the matters, which are pending or may be asserted, could be decided unfavorably to us. Although we maintain liability insurance coverage to protect our assets from losses arising out of or involving activities associated with ongoing and normal business operations, our insurance may not cover, or may not adequately cover, any liabilities that we incur. An adverse ruling or outcome in any lawsuit involving us could materially affect our business, liquidity, consolidated financial position or results of operations. In view of the unpredictable nature of such matters, we cannot provide any assurances regarding the outcome of any litigation, investigation, inquiry or claim to which we are a party or the impact on us of an adverse ruling of such matters.

Item 1A. Risk Factors

You should consider carefully the following information about the risks described below, together with the other information contained in this Quarterly Report and in our other public filings in evaluating our business. The risk factors set forth below that are marked with an asterisk (*) did not appear as separate risk factors in, or contain changes to the similarly titled risk factors included in, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2015. If any of the following risks actually occur, our business, financial condition, results of operations, and future growth prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock would likely decline.

Risks Related to Our Financial Condition and Need for Additional Capital

We have incurred losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable future, and our future profitability is uncertain.*

We have incurred losses in each year since our inception in 1992. Prior to our merger with Biocontrol in January 2011, our accumulated deficit was $315.5 million. Since January 2011 through March 31, 2016, we have incurred a cumulative deficit of $50.1 million, and we expect to incur losses for the foreseeable future. We have devoted, and will continue to devote for the foreseeable future, substantially all of our resources to research and development of our product candidates. For the three months ended March 31, 2016 we had an operating loss of $3.1 million. Additional information regarding our results of operations may be found in our consolidated financial statements and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included elsewhere in this report.

| 21

Clinical trials and activities associated with discovery research are costly. We do not expect to generate any revenue from the commercial sales of our product candidates in the near term, and we expect to continue to have significant losses for the foreseeable future.

To attain ongoing profitability, we will need to develop products successfully and market and sell them effectively, or rely on other parties to do so. We cannot predict when we will achieve ongoing profitability, if at all. We have never generated revenue from the commercial sales of our product candidates, and there is no guarantee that we will be able to do so in the future. If we fail to become profitable, or if we are unable to fund our continuing losses, we would be unable to continue our research and development programs.

We have never generated any revenue from product sales and may never be profitable.

Our ability to generate meaningful revenue and achieve profitability depends on our ability, and the ability of any third party with which we may partner, to successfully complete the development of, and obtain the regulatory approvals necessary to, commercialize our product candidates. We do not anticipate generating revenues from product sales for the foreseeable future, if ever. If any of our product candidates fail in clinical trials or if any of our product candidates do not gain regulatory approval, or if any of our product candidates, if approved, fail to achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our ability to generate future revenues from product sales depends heavily on our success in:

| · | completing research and preclinical and clinical development of our product candidates;
| · | seeking and obtaining regulatory and marketing approvals for product candidates for which we complete clinical trials;
| · | developing a sustainable, scalable, reproducible, and transferable manufacturing process for our product candidates;
| · | launching and commercializing product candidates for which we obtain regulatory and marketing approval, either by establishing a sales force, marketing and distribution infrastructure, or by collaborating with a partner;
| · | obtaining market acceptance of any approved products;
| · | addressing any competing technological and market developments;
| · | implementing additional internal systems and infrastructure, as needed;
| · | identifying and validating new product candidates;
| · | negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter;
| · | maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how; and
| · | attracting, hiring and retaining qualified personnel.

Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product. Our expenses could increase beyond expectations if we are required by the FDA, the EMA, or other foreign regulatory authorities to perform clinical trials and other studies in addition to those that we currently anticipate. Even if we are able to generate revenues from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

We will need to raise additional capital to continue operations.*

Our consolidated financial statements for the quarter ended March 31, 2016 were prepared under the assumption that we would continue our operations as a going concern. However, we have had recurring losses from operations, negative operating cash flow and an accumulated deficit.

We do not generate any cash from operations and must raise additional funds in order to continue operating our business. We expect to continue to fund our operations primarily through equity and debt financings in the future. If additional capital is not available to us when needed or on acceptable terms, we may not be able to continue to operate our business pursuant to our business plan or we may have to discontinue our operations entirely. As of March 31, 2016, we had cash and cash equivalents of $6.2 million. We believe that our existing resources will be sufficient to fund our planned operations into the third quarter of 2016.

Developing drugs and conducting clinical trials is expensive. Our future funding requirements will depend on many factors, including:

| · | the costs and timing of our research and development activities;
| · | the progress and cost of our clinical trials and other research and development activities;
| · | the cost and timing of securing manufacturing capabilities for our clinical product candidates and commercial products, if any;
| · | the terms and timing of any collaborative, licensing, acquisition or other arrangements that we may establish;
| · | the costs and timing of seeking regulatory approvals;
| · | the costs of filing, prosecuting, defending and enforcing any patent applications, claims, patents and other intellectual property rights; and
| · | the costs of lawsuits involving us or our product candidates.

| 22

We will need to raise additional capital to support our product development activities in 2016 and beyond. We may seek funds through arrangements with collaborators or others that may require us to relinquish rights to the products candidates that we might otherwise seek to develop or commercialize independently. We cannot be certain that we will be able to enter into any such arrangements on reasonable terms, if at all.

We may seek to raise capital through a variety of sources, including:

| · | the public equity market;
| · | private equity financings;
| · | collaborative arrangements;
| · | licensing arrangements; and/or
| · | public or private debt.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. Our ability to raise additional funds will depend, in part, on the status of our product development activities and other business operations, as well as factors related to financial, economic, and market conditions, many of which are beyond our control. We cannot be certain that sufficient funds will be available to us when required or on acceptable terms, if at all. Raising additional capital through the sale of securities could cause significant dilution to our stockholders. If adequate funds are not available, we may be required to significantly reduce or refocus our operations or to obtain funds through additional arrangements that may require us to relinquish rights to certain of our products, technologies or potential markets, any of which could delay or require that we curtail or eliminate some or all of our development programs or otherwise have a material adverse effect on our business, financial condition and results of operations. In addition, we may have to delay, reduce the scope of or eliminate some of our research and development, which could delay the time to market for any of our product candidates, if adequate funds are not available.

If we are unable to secure additional financing on a timely basis or on terms acceptable to us, we may be required to cease or reduce certain research and development projects, to sell some or all of our technology or assets or to merge all or a portion of our business with another entity. Insufficient funds may require us to delay, scale back, or eliminate some or all of our activities, and if we are unable to obtain additional funding, there is uncertainty regarding our continued existence.

A complaint has been filed against us and the members of our Board of Directors by one of our principal shareholders.*

On April 8, 2016, certain holders (the “Holders”) of over two-thirds of our then-outstanding shares of Series B redeemable convertible preferred stock (“Series B Preferred”) elected to automatically convert all outstanding shares of Series B Preferred into shares of Common Stock in accordance with Section 4.4.4(b)(ii) of our Amended and Restated Articles of Incorporation, as amended (the “Conversion”). As a result of the Conversion, the 7,527,853 shares of Series B Preferred outstanding as of immediately prior to the Conversion were automatically converted into an aggregate of 1,505,560 shares of our common stock. On April 8, 2016, we entered into a Common Stock Issuance Agreement (the “CSIA”) with the Holders pursuant to which we issued to the Holders an aggregate of 853,465 shares of our Common Stock (the “Shares”) and amended the common stock warrants issued to the Holders pursuant to that certain Subscription Agreement, dated June 25, 2013, in order to reduce the exercise price of such warrants from $7.00 per share to $4.05 per share and extend the expiration date thereof from June 26, 2018 to March 31, 2021 (the “Warrant Amendments”). As consideration for the Shares and the Warrant Amendments, the Holders waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the Conversion in respect of accrued dividends on their former shares of Series B Preferred.

On April 14, 2016, NRM VII Holdings I, LLC (“NRM”), who was not a party to the CSIA, filed a complaint against us and each of the current members of our board of directors in the Superior Court of California, County of San Diego. Prior to the Conversion, NRM held approximately 28.5% of our outstanding shares of Series B Preferred. The complaint alleges that we breached the implied covenant of good faith by entering into a scheme to force NRM to convert its Series B Preferred into common stock. The complaint further alleges that the current members of our board of directors breached their fiduciary duty of good faith owed to NRM, as one of our shareholders, by participating in this transaction. The complaint seeks unspecified monetary damages and other relief. We plan to vigorously defend against the claims advanced.

Litigation is subject to inherent uncertainties, and an adverse result in the matter described above or other matters that may arise from time to time could have a material adverse effect on our business, results of operations and financial condition. Any litigation to which we are subject may be costly and, further, could require significant involvement of our senior management and may divert management’s attention from our business and operations. In addition, our share price may be negatively impacted due to the negative publicity, expenses incurred in connection with our defense, management distraction, and/or other factors related to this litigation. In addition, litigation of this nature may negatively impact our ability to attract and retain strategic partners, as well as qualified board members and management personnel.

| 23

There is substantial doubt about our ability to continue as a going concern, which may affect our ability to obtain future financing and may require us to curtail our operations.*

Our financial statements as of March 31, 2016 were prepared under the assumption that we will continue as a going concern. Our financial statements do not include any adjustments that might result from the outcome of this uncertainty. At March 31, 2016, we had cash and cash equivalents of $6.2 million. Our ability to continue as a going concern depends on our ability to raise substantial additional funds through public or private equity offerings, collaborative or licensing arrangements and/or debt financing.

Taxing authorities could reallocate our taxable income among our subsidiaries, which could increase our overall tax liability.

We are organized in the United States, and we currently have subsidiaries in the United Kingdom, Australia and Slovenia. If we succeed in growing our business, we expect to conduct increased operations through our subsidiaries in various tax jurisdictions pursuant to transfer pricing arrangements between us and our subsidiaries. If two or more affiliated companies are located in different countries, the tax laws or regulations of each country generally will require that transfer prices be the same as those between unrelated companies dealing at arms’ length and that appropriate documentation is maintained to support the transfer prices. While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities.

If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arms’ length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us. In addition, if the country from which the income is reallocated does not agree with the reallocation, both countries could tax the same income, resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it would increase our consolidated tax liability, which could adversely affect our financial condition, results of operations and cash flows.

Our ability to use our net operating tax loss carryforwards and certain other tax attributes may be limited.*

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”). These limitations apply if an “ownership change,” as defined by Section 382 of the Code, occurs. If we have experienced an “ownership change” at any time since our formation, we may already be subject to limitations on our ability to utilize our existing net operating losses and other tax attributes to offset taxable income. In addition, future changes in our stock ownership (including in connection with future private or public offerings, as well as changes that may be outside of our control), may trigger an “ownership change” and, consequently, limitations under Sections 382 and 383 of the Code. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards and other pre-change tax attributes to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. We have not completed a study to assess whether an “ownership change” has occurred or whether there have been multiple “ownership changes” since our formation, due to the complexity and cost associated with such a study, and the fact that there may be additional ownership changes in the future.

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate financial statements on a timely basis could be impaired and our public reporting may be unreliable.*

We are required to maintain internal control over financial reporting adequate to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements in accordance with generally accepted accounting principles. In connection with the restatement of our consolidated financial statements for the second quarter of 2015 and for the quarterly and annual periods of 2014, we determined that we had a material weakness as of December 31, 2014 and December 31, 2015, namely that our internal control over financial reporting, including control over the evaluation and review of complex and non-routine transactions, were not effective. A material weakness means a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis.

We do not expect that our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. Over time, controls may become inadequate because changes in conditions or deterioration in the degree of compliance with policies or procedures may occur. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. As a result, we cannot assure you that significant deficiencies or material weaknesses in our internal control over financial reporting will not be identified in the future.

We are taking steps to remediate the material weakness in our internal control over financial reporting, including designing additional training programs for relevant personnel and developing specific review procedures regarding the review of complex and non-routine transactions. However, we cannot assure you that these efforts will remediate our material weakness in a timely manner, or at all. If we are unable to successfully remediate our material weakness, or identify any future material weaknesses, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports and we may experience a loss of public confidence, which could have an adverse effect on our business, financial condition and the market price of our common stock and other securities.

| 24

We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses. We are subject to the reporting requirements of the Exchange Act, which require, among other things, that we file with the SEC annual, quarterly and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, as well as rules subsequently adopted by the SEC and the NYSE MKT to implement provisions of the Sarbanes-Oxley Act, imposes significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. Further, in July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and executive compensation related provisions in the Dodd-Frank Act that require the SEC to adopt additional rules and regulations in these areas such as “say on pay” and proxy access. Recent legislation permits emerging growth companies to implement many of these requirements over a longer period and up to five years following their initial public offering. We intend to take advantage of this new legislation but cannot guarantee that we will not be required to implement these requirements sooner than expected and thereby incur unexpected expenses.

We expect the rules and regulations applicable to public companies to result in us continuing to incur substantial legal and financial compliance costs. These costs will decrease our net income or increase our net loss, and may require us to reduce costs in other areas of our business.

Risks Related to Our Business

We are seeking to develop antibacterial agents using bacteriophage technology, a novel approach, which makes it difficult to predict the time and cost of development. No bacteriophage products have been approved in the United States or elsewhere.

We are developing our product candidates with bacteriophage technology. We have not, nor to our knowledge has any other company, received regulatory approval from the FDA or equivalent foreign agencies for a pharmaceutical drug based on this approach. While in vitro studies have characterized the behavior of bacteriophages in cell cultures and there exists a body of literature regarding the use of phage therapy in humans, the safety and efficacy of phage therapy in humans has not been extensively studied in well-controlled modern clinical trials. Most of the prior research on phage-based therapy was conducted in the former Soviet Union prior to and immediately after World War II and lacked appropriate control group design or lacked control groups at all. Furthermore, the standard of care has changed substantially during the ensuing decades since those studies were performed, diminishing the relevance of prior claims of improved cure rates. We cannot be certain that our approach will lead to the development of approvable or marketable drugs.

Developing phage-based therapies on a commercial scale will also require developing new manufacturing processes and techniques. We and our third-party collaborators may experience delays in developing manufacturing capabilities for our product candidates, and may not be able to do so at the scale required to efficiently conduct the clinical trials required to obtain regulatory approval of our product candidates, or to manufacture commercial quantities of our products, if approved.

In addition, the FDA or other regulatory agencies may lack experience in evaluating the safety and efficacy of drugs based on these approaches, which could lengthen the regulatory review process, increase our development costs and delay or prevent commercialization of our product candidates.

Delays in our clinical trials could result in us not achieving anticipated developmental milestones when expected, increased costs and delay our ability to obtain regulatory approval for and commercialize our product candidates.

Delays in our ability to commence or enroll patients for our clinical trials could result in us not meeting anticipated clinical milestones and could materially impact our product development costs and delay regulatory approval of our product candidates. Planned clinical trials may not be commenced or completed on schedule, or at all. Clinical trials can be delayed for a variety of reasons, including:

| · | delays in the development of manufacturing capabilities for our product candidates to enable their consistent production at clinical trial scale;
| · | failures in our internal manufacturing operations that result in our inability to consistently and timely produce bacteriophages in sufficient quantities to support our clinical trials;
| · | the availability of financial resources to commence and complete our planned clinical trials;
| · | delays in reaching a consensus with clinical investigators on study design;
| · | delays in reaching a consensus with regulatory agencies on trial design or in obtaining regulatory approval to commence a trial;
| · | delays in obtaining clinical materials;
| · | slower than expected patient recruitment for participation in clinical trials;

| 25

| · | failure by clinical trial sites, other third parties, or us to adhere to clinical trial agreements;
| · | delays in reaching agreement on acceptable clinical trial agreement terms with prospective sites or obtaining institutional review board approval; and
| · | adverse safety events experienced during our clinical trials.

If we do not successfully commence or complete our clinical trials on schedule, the price of our common stock may decline.

Completion of clinical trials depends, among other things, on our ability to enroll a sufficient number of patients, which is a function of many factors, including:

| · | the therapeutic endpoints chosen for evaluation;
| · | the eligibility criteria defined in the protocol;
| · | the perceived benefit of the product candidate under study;
| · | the size of the patient population required for analysis of the clinical trial’s therapeutic endpoints;
| · | our ability to recruit clinical trial investigators and sites with the appropriate competencies and experience;
| · | our ability to obtain and maintain patient consents; and
| · | competition for patients from clinical trials for other treatments.

We may experience difficulties in enrolling patients in our clinical trials, which could increase the costs or affect the timing or outcome of these clinical trials. This is particularly true with respect to diseases with relatively small patient populations.

We have not completed formulation development of any of our product candidates.

The development of our bacteriophage product candidates requires that we isolate, select and combine a number of bacteriophages that target the desired bacteria for that product candidate. The selection of bacteriophages for any of our product candidates is based on a variety of factors, including without limitation the ability of the selected phages, in combination, to successfully kill the targeted bacteria, the degree of cross-reactivity of the individual phages with the same part of the bacterial targets, the ability of the combined phages to satisfy regulatory requirements, our ability to manufacture sufficient quantities of the phages, intellectual property rights of third parties, and other factors. While we have selected an initial formulation of AB-SA01 for the treatment of S. aureus infections, there can be no assurance that this will be the final formulation of AB-SA01 for commercialization. In addition, we have initiated final phage selection for AB-PA01, our P. aeruginosa product. AB-CD01, which is our C. difficile product, is at an earlier stage. If we are unable to complete formulation development of our product candidates in the time frame that we have anticipated, then our product development timelines, and the regulatory approval of our product candidates, could be delayed.

Our product candidates must undergo rigorous clinical testing, such clinical testing may fail to demonstrate safety and efficacy and any of our product candidates could cause undesirable side effects, which would substantially delay or prevent regulatory approval or commercialization.

Before we can obtain regulatory approval for a product candidate, we must undertake extensive clinical testing in humans to demonstrate safety and efficacy to the satisfaction of the FDA or other regulatory agencies. Clinical trials of new drug candidates sufficient to obtain regulatory marketing approval are expensive and take years to complete.

We cannot be certain of successfully completing clinical testing within the time frame we have planned, or at all. We may experience numerous unforeseen events during, or as a result of, the clinical trial process that could delay or prevent us from receiving regulatory approval or commercializing our product candidates, including the following:

| · | our clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical and/or preclinical testing or to abandon programs;
| · | the results obtained in earlier stage clinical testing may not be indicative of results in future clinical trials;
| · | clinical trial results may not meet the level of statistical significance required by the FDA or other regulatory agencies;
| · | we, or regulators, may suspend or terminate our clinical trials if the participating patients are being exposed to unacceptable health risks; and
| · | our product candidates may have unintended or undesirable effects on patients that may delay or preclude regulatory approval of our product candidates or limit their commercial use, if approved.

Results from preclinical studies and Phase 1 or 2 clinical trials of our product candidates may not be predictive of the results of later stage human clinical trials.

Preclinical studies, including studies of our product candidates in animal disease models, may not accurately predict the result of human clinical trials of those product candidates. In particular, promising animal studies suggesting the efficacy of prototype phage products in the treatment of bacterial infections, such as P. aeruginosa and S. aureus, may not predict the ability of these products to treat similar infections in humans. Our phage technology may be found not to be efficacious in treating bacterial infections alone or in combination with other agents, when studied in human clinical trials.

| 26

To satisfy FDA or foreign regulatory approval standards for the commercial sale of our product candidates, we must demonstrate in adequate and controlled clinical trials that our product candidates are safe and effective. Success in early clinical trials, including Phase 2 trials, does not ensure that later clinical trials will be successful. Our initial results from early stage clinical trials also may not be confirmed by later analysis or subsequent larger clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier clinical trials and most product candidates that commence clinical trials are never approved for commercial sale.

We must continue to develop manufacturing processes for our product candidates and any delay in or our inability to do so would result in delays in our clinical trials.

We are developing novel manufacturing processes for our product candidates at our facility in Ljubljana, Slovenia. The manufacturing processes for our product candidates, and the scale up of such processes for clinical trials, is novel, and there can be no assurance that we will be able to complete this work in a timely manner, if at all. Any delay in the development or scale up of these manufacturing processes could delay the start of clinical trials and harm our business. Our facility in Slovenia must also undergo ongoing inspections by JAZMP, the Slovenian agency that regulates and supervises pharmaceutical products in Slovenia, for compliance with their and the European Medicines Agency’s, or EMA’s, current good manufacturing practice regulations, or cGMP regulations, before the respective product candidates can be approved for use in clinical trials or commercialization. In the event these facilities do not receive a satisfactory cGMP inspection for the manufacture of our product candidates, we may need to fund additional modifications to our manufacturing process, conduct additional validation studies, or find alternative manufacturing facilities, any of which would result in significant cost to us as well as a delay of up to several years in obtaining approval for such product candidate.

Our manufacturing facility will be subject to ongoing periodic inspection by the European regulatory authorities, including JAZMP, and the FDA for compliance with European and FDA cGMP regulations. Compliance with these regulations and standards is complex and costly, and there can be no assurance that we will be able to comply. Any failure to comply with applicable regulations could result in sanctions being imposed (including fines, injunctions and civil penalties), failure of regulatory authorities to grant marketing approval of our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecution.

We may conduct clinical trials for our products or product candidates outside the United States and the FDA may not accept data from such trials.

We are currently conducting an investigator-sponsored clinical trial of AB-SA01 at the University of Adelaide in Australia for chronic rhinosinusitis, and may seek to conduct one or more other clinical trials in the future outside the United States. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of such study data by the FDA is subject to certain conditions. For example, the study must be well designed and conducted and performed by qualified investigators in accordance with ethical principles. The study population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Generally, the patient population for any clinical studies conducted outside of the United States must be representative of the population for whom we intend to label the product in the United States. In addition, such studies would be subject to the applicable local laws and FDA acceptance of the data would be dependent upon its determination that the studies also complied with all applicable U.S. laws and regulations. There can be no assurance the FDA will accept data from trials conducted outside of the United States. If the FDA does not accept any such data, it would likely result in the need for additional trials, which would be costly and time consuming and delay aspects of our business plan.

We may need to license additional intellectual property rights.

The development and commercialization of phage-based antibacterial agents may require us to obtain rights to intellectual property from third parties. For example, pursuant to our Collaborative Research and Development Agreement with the United States Army Medical Research and Materiel Command and the Walter Reed Army Institute of Research, we are currently focusing on developing bacteriophage therapeutics to treat S. aureus infections. To the extent the intellectual property is generated from the United States Army Medical Research and Materiel Command or Walter Reed Army Institute of Research that is used in a commercial product, we may be obligated to make payments such as royalties, licensing fees and milestone payments. We may also determine that it is necessary or advisable to license other intellectual property from third parties. There can be no assurance that such intellectual property rights would be available on commercially reasonable terms, if at all.

We are conducting an investigator-sponsored clinical trial of AB-SA01 at the University of Adelaide. To the extent that intellectual property is generated as a result of the study that is used in a commercial product, we may be obligated to make payments, such as royalties, licensing fees, and milestone payments. There can be no assurance that such intellectual property rights would be available on commercially reasonable terms, if at all.

We are subject to significant regulatory approval requirements, which could delay, prevent or limit our ability to market our product candidates.

Our research and development activities, preclinical studies, clinical trials and the anticipated manufacturing and marketing of our product candidates are subject to extensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in Europe and elsewhere. There can be no assurance that our manufacturing facilities will satisfy the requirements of the FDA or comparable foreign authorities. We require the approval of the relevant regulatory authorities before we may commence commercial sales of our product candidates in a given market. The regulatory approval process is expensive and time-consuming, and the timing of receipt of regulatory approval is difficult to predict. Our product candidates could require a significantly longer time to gain regulatory approval than expected, or may never gain approval. We cannot be certain that, even after expending substantial time and financial resources, we will obtain regulatory approval for any of our product candidates. A delay or denial of regulatory approval could delay or prevent our ability to generate product revenues and to achieve profitability.

Changes in regulatory approval policies during the development period of any of our product candidates, changes in, or the enactment of, additional regulations or statutes, or changes in regulatory review practices for a submitted product application may cause a delay in obtaining approval or result in the rejection of an application for regulatory approval.

Regulatory approval, if obtained, may be made subject to limitations on the indicated uses for which we may market a product. These limitations could adversely affect our potential product revenues. Regulatory approval may also require costly post-marketing follow-up studies. In addition, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping related to the product will be subject to extensive ongoing regulatory requirements. Furthermore, for any marketed product, its manufacturer and its manufacturing facilities will be subject to continual review and periodic inspections by the FDA or other regulatory authorities. Failure to comply with applicable regulatory requirements may, among other things, result in fines, suspensions of regulatory approvals, product recalls, product seizures, operating restrictions and criminal prosecution.

A variety of risks associated with our international operations could materially adversely affect our business.

In addition to our U.S. operations, we have operations and subsidiaries in the United Kingdom, Australia and Slovenia. We face risks associated with our international operations, including possible unfavorable regulatory, pricing and reimbursement, political, tax and labor conditions, which could harm our business. We are subject to numerous risks associated with international business activities, including:

| · | compliance with differing or unexpected regulatory requirements for the development, manufacture and, if approved, commercialization of our product candidates;
| · | difficulties in staffing and managing foreign operations;
| · | foreign government taxes, regulations and permit requirements;
| · | U.S. and foreign government tariffs, trade restrictions, price and exchange controls and other regulatory requirements;
| · | anti-corruption laws, including the Foreign Corrupt Practices Act, or the FCPA;
| · | economic weakness, including inflation, natural disasters, war, events of terrorism or political instability in particular foreign countries;
| · | fluctuations in currency exchange rates, which could result in increased operating expenses and reduced revenues, and other obligations related to doing business in another country;
| · | compliance with tax, employment, immigration and labor laws, regulations and restrictions for employees living or traveling abroad;
| · | workforce uncertainty in countries where labor unrest is more common than in the United States;
| · | production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad;
| · | changes in diplomatic and trade relationships; and
| · | challenges in enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect intellectual property rights to the same extent as the United States.

These and other risks associated with our international operations may materially adversely affect our business, financial condition and results of operations.

We do not have a sales force and do not currently have plans to develop one.

The commercial success of any of our product candidates will depend upon the strength of sales and marketing efforts for them. We do not have a sales force and have no experience in sales, marketing or distribution. To successfully commercialize our product candidates, we will need to develop such a capability ourselves or seek assistance from a third party with a large distribution system and a large direct sales force. We may be unable to put such a plan in place. In addition, if we arrange for others to market and sell our products, our revenues will depend upon the efforts of those parties. Such arrangements may not succeed. Even if one or more of our product candidates is approved for marketing, if we fail to establish adequate sales, marketing and distribution capabilities, independently or with others, our business will be materially harmed.

| 28

Our success depends in part on attracting, retaining and motivating our personnel.*

Our success depends on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel and on our ability to develop and maintain important relationships with leading academic institutions, clinicians and scientists. As of May 6, 2016, we had 30 employees. Our success will depend on our ability to retain and motivate personnel and hire additional qualified personnel when required. Competition for qualified personnel in the biotechnology field is intense. We face competition for personnel from other biotechnology and pharmaceutical companies, universities, public and private research institutions and other organizations. We also face competition from other more well-funded and well-established businesses and we may also be viewed as a riskier choice from a job stability perspective due to our relative newer status than longer existing biotech and pharmaceutical companies. We may not be able to attract and retain qualified personnel on acceptable terms given the competition for such personnel. If we are unsuccessful in our retention, motivation and recruitment efforts, we may be unable to execute our business strategy.

We must manage a geographically dispersed organization.

While we are a small company, we currently have operations in the United States, United Kingdom, Australia and Slovenia. In the future, we may also locate facilities in other locations based on proximity to personnel with the expertise needed to research, develop and manufacture phage-based therapeutics, costs of operations or other factors. Managing our organization across multiple locations and multiple time zones may reduce our efficiency, increase our expenses and increase the risk of operational difficulties in the execution of our plans.

Risks Related to Our Reliance on Third Parties

We rely on third parties for aspects of product development.

We rely on third parties such as the University of Leicester and the U.S. Army for certain aspects of product development. We are working with the University of Leicester for research and development of product candidates to treat C. difficile infections. We are working with the U.S. Army for research and development of product candidates to treat S. aureus infections. Because we rely on third parties to conduct these activities, we have less control over the success of these programs than we would if we were conducting them on our own. Factors beyond our control that could impact the success of these programs include the amount of resources devoted to the programs by the applicable third party, the staffing of those projects by third-party personnel, and the amount of time such personnel devote to our programs compared to other programs. Failure of our third-party collaborators to successfully complete the projects that we are working on with them could result in delays in product development and the need to expend additional resources, increasing our expenses beyond current expectations.

We will rely on third parties to conduct our clinical trials, and their failure to perform their obligations in a timely or competent manner may delay development and commercialization of our product candidates.

We expect to use third parties, such as clinical research organizations or the U.S. Army, to assist in conducting our clinical trials. However, we may face delays outside of our control if these parties do not perform their obligations in a timely or competent fashion or if we are forced to change service providers. This risk is heightened for clinical trials conducted outside of the United States, where it may be more difficult to ensure that clinical trials are conducted in compliance with FDA requirements. Any third party that we hire to conduct clinical trials may also provide services to our competitors, which could compromise the performance of their obligations to us. If we experience significant delays in the progress of our clinical trials and in our plans to submit Biologics License Applications, the commercial prospects for product candidates could be harmed and our ability to generate product revenue would be delayed or prevented.

Risks Related to Our Intellectual Property

We are dependent on patents and proprietary technology. If we fail to adequately protect this intellectual property or if we otherwise do not have exclusivity for the marketing of our products, our ability to commercialize products could suffer.

Our commercial success will depend in part on our ability to obtain and maintain patent protection sufficient to prevent others from marketing our product candidates, as well as to defend and enforce these patents against infringement and to operate without infringing the proprietary rights of others. Protection of our product candidates from unauthorized use by third parties will depend on having valid and enforceable patents cover our product candidates or their manufacture or use, or having effective trade secret protection. If our patent applications do not result in issued patents, or if our patents are found to be invalid, we will lose the ability to exclude others from making, using or selling the inventions claimed therein. We have a limited number of patents and pending patent applications.

The patent positions of biotechnology companies can be uncertain and involve complex legal and factual questions. This is due to inconsistent application of policy and changes in policy relating to examination and enforcement of biotechnology patents to date on a global scale. The laws of some countries may not protect intellectual property rights to the same extent as the laws of countries having well-established patent systems, and those countries may lack adequate rules and procedures for defending our intellectual property rights. Also, changes in either patent laws or in interpretations of patent laws may diminish the value of our intellectual property. We are not able to guarantee that all of our patent applications will result in the issuance of patents and we cannot predict the breadth of claims that may be allowed in our patent applications or in the patent applications we may license from others.

Central provisions of The Leahy-Smith America Invents Act, or the America Invents Act went into effect on September 16, 2012 and on March 16, 2013. The America Invents Act includes a number of significant changes to U.S. patent law. These changes include provisions that affect the way patent applications are being filed, prosecuted and litigated. For example, the America Invents Act enacted proceedings involving post-issuance patent review procedures, such as inter partes review, or IPR, and post-grant review, that allow third parties to challenge the validity of an issued patent in front of the United States PTO Patent Trial and Appeal Board. Each proceeding has different eligibility criteria and different patentability challenges that can be raised. IPRs permit any person (except a party who has been litigating the patent for more than a year) to challenge the validity of the patent on the grounds that it was anticipated or made obvious by prior art. Patents covering pharmaceutical products have been subject to attack in IPRs from generic drug companies and from hedge funds. If it is within nine months of the issuance of the challenged patent, a third party can petition the United States PTO for post-grant review, which can be based on any invalidity grounds and is not limited to prior art patents or printed publications.

In post-issuance proceedings, United States PTO rules and regulations generally tend to favor patent challengers over patent owners. For example, unlike in district court litigation, claims challenged in post-issuance proceedings are given their broadest reasonable meaning, which increases the chance a claim might be invalidated by prior art or lack support in the patent specification. The United States Supreme Court is currently reviewing whether it is proper for the United States PTO to give claims their broadest reasonable meaning in post-issuance proceedings. As another example, unlike in district court litigation, there is no presumption of validity for an issued patent, and thus, a challenger’s burden to prove invalidity is by a preponderance of the evidence, as opposed to the heightened clear and convincing evidence standard. As a result of these rules and others, statistics released by the United States PTO show a high percentage of claims being invalidated in post-issuance proceedings. Moreover, with few exceptions, there is no standing requirement to petition the United States PTO for inter partes review or post-grant review. In other words, companies that have not been charged with infringement or that lack commercial interest in the patented subject matter can still petition the United States PTO for review of an issued patent. Thus, even where we have issued patents, our rights under those patents may be challenged and ultimately not provide us with sufficient protection against competitive products or processes.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

| · | we might not be the first to file patent applications for our inventions;
| · | others may independently develop similar or alternative product candidates to any of our product candidates that fall outside the scope of our patents;
| · | our pending patent applications may not result in issued patents;
| · | our issued patents may not provide a basis for commercially viable products or may not provide us with any competitive advantages or may be challenged by third parties;
| · | others may design around our patent claims to produce competitive products that fall outside the scope of our patents;
| · | we may not develop additional patentable proprietary technologies related to our product candidates; and
| · | we are dependent upon the diligence of our appointed agents in national jurisdictions, acting for and on our behalf, which control the prosecution of pending domestic and foreign patent applications and maintain granted domestic and foreign patents.

An issued patent does not guarantee us the right to practice the patented technology or commercialize the patented product. Third parties may have blocking patents that could be used to prevent us from commercializing our patented products and practicing our patented technology. Our issued patents and those that may be issued in the future may be challenged, invalidated or circumvented, which could limit our ability to prevent competitors from marketing the same or related product candidates or could limit the length of the term of patent protection of our product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any of our product candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of the patent. Patent term extensions may not be available for these patents.

We rely on trade secrets and other forms of non-patent intellectual property protection. If we are unable to protect our trade secrets, other companies may be able to compete more effectively against us.

We rely on trade secrets to protect certain aspects of our technology, including our proprietary processes for manufacturing and purifying bacteriophages. Trade secrets are difficult to protect, especially in the pharmaceutical industry, where much of the information about a product must be made public during the regulatory approval process. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using our trade secret information is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to or may not protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

If we are sued for infringing intellectual property rights of third parties or if we are forced to engage in an interference proceeding, it will be costly and time-consuming, and an unfavorable outcome in that litigation or interference would have a material adverse effect on our business.

Our ability to commercialize our product candidates depends on our ability to develop, manufacture, market and sell our product candidates without infringing the proprietary rights of third parties. Numerous United States and foreign patents and patent applications, which are owned by third parties, exist in the general field of anti-infective products or in fields that otherwise may relate to our product candidates. If we are shown to infringe, we could be enjoined from use or sale of the claimed invention if we are unable to prove that the patent is invalid. In addition, because patent applications can take many years to issue, there may be currently pending patent applications, unknown to us, which may later result in issued patents that our product candidates may infringe, or which may trigger an interference proceeding regarding one of our owned or licensed patents or applications. There could also be existing patents of which we are not aware that our product candidates may inadvertently infringe or which may become involved in an interference proceeding.

| 30

The biotechnology and pharmaceutical industries are characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement. For so long as our product candidates are in clinical trials, we believe our clinical activities fall within the scope of the exemptions provided by 35 U.S.C. Section 271(e) in the United States, which exempts from patent infringement liability activities reasonably related to the development and submission of information to the FDA. As our clinical investigational drug product candidates progress toward commercialization, the possibility of a patent infringement claim against us increases. While we attempt to ensure that our active clinical investigational drugs and the methods we employ to manufacture them, as well as the methods for their use we intend to promote, do not infringe other parties’ patents and other proprietary rights, we cannot be certain they do not, and competitors or other parties may assert that we infringe their proprietary rights in any event.

We may be exposed to future litigation based on claims that our product candidates, or the methods we employ to manufacture them, or the uses for which we intend to promote them, infringe the intellectual property rights of others. Our ability to manufacture and commercialize our product candidates may depend on our ability to demonstrate that the manufacturing processes we employ and the use of our product candidates do not infringe third-party patents. If third-party patents were found to cover our product candidates or their use or manufacture, we could be required to pay damages or be enjoined and therefore unable to commercialize our product candidates, unless we obtained a license. A license may not be available to us on acceptable terms, if at all.

Risks Related to Our Industry

If our competitors are able to develop and market products that are more effective, safer or more affordable than ours, or obtain marketing approval before we do, our commercial opportunities may be limited.

Competition in the biotechnology and pharmaceutical industries is intense and continues to increase. Some companies that are larger and have significantly more resources than we do are aggressively pursuing antibacterial development programs, including traditional therapies and therapies with novel mechanisms of action. In addition, other companies are developing phage-based products for non-therapeutic uses, and may elect to use their expertise in phage development and manufacturing to try to develop products that would compete with ours.

We also face potential competition from academic institutions, government agencies and private and public research institutions engaged in the discovery and development of drugs and therapies. Many of our competitors have significantly greater financial resources and expertise in research and development, preclinical testing, conducting clinical trials, obtaining regulatory approvals, manufacturing, sales and marketing than we do. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established pharmaceutical companies.

Our competitors may succeed in developing products that are more effective, have fewer side effects and are safer or more affordable than our product candidates, which would render our product candidates less competitive or noncompetitive. These competitors also compete with us to recruit and retain qualified scientific and management personnel, establish clinical trial sites and patient registration for clinical trials, as well as to acquire technologies and technology licenses complementary to our programs or advantageous to our business. Moreover, competitors that are able to achieve patent protection, obtain regulatory approvals and commence commercial sales of their products before we do, and competitors that have already done so, may enjoy a significant competitive advantage.

The Generating Antibiotics Incentives Now Act, or the GAIN Act, is intended to provide incentives for the development of new, qualified infectious disease products. These incentives may result in more competition in the market for new antibiotics, and may cause pharmaceutical and biotechnology companies with more resources than we have to shift their efforts towards the development of products that could be competitive with our product candidates.

There is a substantial risk of product liability claims in our business. If we do not obtain sufficient liability insurance, a product liability claim could result in substantial liabilities.

Our business exposes us to significant potential product liability risks that are inherent in the development, manufacturing and marketing of human therapeutic products. Regardless of merit or eventual outcome, product liability claims may result in:

| · | delay or failure to complete our clinical trials;
| · | withdrawal of clinical trial participants;
| · | decreased demand for our product candidates;
| · | injury to our reputation;
| · | litigation costs;
| · | substantial monetary awards against us; and

| 31

| · | diversion of management or other resources from key aspects of our operations.

If we succeed in marketing products, product liability claims could result in an FDA investigation of the safety or efficacy of our products, our manufacturing processes and facilities or our marketing programs. An FDA investigation could also potentially lead to a recall of our products or more serious enforcement actions, or limitations on the indications, for which they may be used, or suspension or withdrawal of approval.

We have product liability insurance that covers our clinical trials up to a $10.0 million annual per claim and aggregate limit. We intend to expand our insurance coverage to include the sale of commercial products if marketing approval is obtained for our product candidates or any other compound that we may develop. However, insurance coverage is expensive and we may not be able to maintain insurance coverage at a reasonable cost or at all, and the insurance coverage that we obtain may not be adequate to cover potential claims or losses.

Even if we receive regulatory approval to market our product candidates, the market may not be receptive to our product candidates upon their commercial introduction, which would negatively affect our ability to achieve profitability.

Our product candidates may not gain market acceptance among physicians, patients, healthcare payors and the medical community. The degree of market acceptance of any approved products will depend on a number of factors, including:

| · | the effectiveness of the product;
| · | the prevalence and severity of any side effects;
| · | potential advantages or disadvantages over alternative treatments;
| · | relative convenience and ease of administration;
| · | the strength of marketing and distribution support;
| · | the price of the product, both in absolute terms and relative to alternative treatments; and
| · | sufficient third-party coverage or reimbursement.

If our product candidates receive regulatory approval but do not achieve an adequate level of acceptance by physicians, healthcare payors and patients, we may not generate product revenues sufficient to attain profitability.

Foreign governments tend to impose strict price controls, which may adversely affect our future profitability.

In some foreign countries, particularly in the European Union, prescription drug pricing is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our profitability will be negatively affected.

We may incur significant costs complying with environmental laws and regulations, and failure to comply with these laws and regulations could expose us to significant liabilities.

Our research and development activities use biological and hazardous materials that are dangerous to human health and safety or the environment. We are subject to a variety of federal, state and local laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these materials and wastes resulting from these materials. We are also subject to regulation by the Occupational Safety and Health Administration, or OSHA, state and federal environmental protection agencies and to regulation under the Toxic Substances Control Act. OSHA, state governments or federal Environmental Protection Agency, or EPA, may adopt regulations that may affect our research and development programs. We are unable to predict whether any agency will adopt any regulations that could have a material adverse effect on our operations. We have incurred, and will continue to incur, capital and operating expenditures and other costs in the ordinary course of our business in complying with these laws and regulations.

Although we believe our safety procedures for handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot entirely eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of hazardous materials. In the event of contamination or injury, we could be held liable for any resulting damages, and any liability could significantly exceed our insurance coverage.

Risks Related to Our Common Stock

The price of our common stock has been and may continue to be volatile.

The stock markets in general, the markets for biotechnology stocks and, in particular, the stock price of our common stock, have experienced extreme volatility. The market for our common stock is characterized by significant price volatility when compared to the shares of larger, more established companies that trade on a national securities exchange and have large public floats, and we expect that our share price will continue to be more volatile than the shares of such larger, more established companies for the indefinite future. The volatility in our share price is attributable to a number of factors. Our common shares are, compared to the shares of such larger, more established companies, sporadically and thinly traded. As a consequence of this limited liquidity, the trading of relatively small quantities of shares by our stockholders may disproportionately influence the price of those shares in either direction. The price for our shares could, for example, decline precipitously in the event that a large number of shares of our common stock are sold on the market without commensurate demand. We are also a speculative or “risky” investment due to the early stage of our drug development programs and our lack of profits to date, and uncertainty of future market acceptance for our potential products. As a consequence of this enhanced risk, more risk-adverse investors may, under the fear of losing all or most of their investment in the event of negative news or lack of progress, be more inclined to sell their shares on the market more quickly and at greater discounts than would be the case with the stock of a larger, more established company that has a large public float and broader stockholder base. Many of these factors are beyond our control and may decrease the market price of our common stock, regardless of our operating performance. We cannot make any predictions or projections as to what the prevailing market price for our common shares will be at any time, including as to whether our common stock will sustain their current market prices, or as to what effect that the sale of shares or the availability of common stock for sale at any time will have on the prevailing market price.

Price declines in our common stock could also result from general market and economic conditions and a variety of other factors, including:

| · | adverse results or delays in our clinical trials;
| · | adverse actions taken by regulatory agencies with respect to our product candidates, clinical trials or the manufacturing processes of our product candidates;
| · | announcements of technological innovations, patents or new products by our competitors;
| · | regulatory developments in the United States and foreign countries;
| · | any lawsuit involving us or our product candidates;
| · | announcements concerning our competitors, or the biotechnology or pharmaceutical industries in general;
| · | developments concerning any strategic alliances or acquisitions we may enter into;
| · | actual or anticipated variations in our operating results;
| · | changes in recommendations by securities analysts or lack of analyst coverage;
| · | deviations in our operating results from the estimates of analysts;
| · | sales of our common stock by our executive officers, directors and principal stockholders or sales of substantial amounts of common stock; and
| · | loss of any of our key scientific or management personnel.

In the past, following periods of volatility in the market price of a particular company’s securities, litigation has often been brought against that company. Any such lawsuit could consume resources and management time and attention, which could adversely affect our business.

We may be required to issue a significant number of additional shares of common stock for no additional consideration and/or make cash make-whole payments to certain of our stockholders.*

We may be required to issue a significant number of additional shares of common stock for no additional consideration and/or make cash make-whole payments to the Holders. Pursuant to the CSIA, we agreed that if in the future we conduct one or more bona fide equity financings in which we sell shares of our common stock or preferred stock at a price of less than $4.05 per share (each, a “Dilutive Financing”), we will issue to the Holders, for no additional consideration, a number of additional shares of common stock (“Additional Shares”) based on a specified formula (such rights of the Holders to receive Additional Shares, the “Additional Issuance Rights”). Specifically, in the event we conduct a Dilutive Financing, the Holders will be entitled to receive (absent consideration of any applicable restrictions on the number of shares that can be issued in a non-public offering under NYSE MKT rules and interpretations without shareholder approval) in the aggregate a number of Additional Shares equal to (A) the product of (x) 1,037,053 multiplied by (y) a fraction, the numerator of which is $4.05 and the denominator of which is the lowest price per share paid by investors in such Dilutive Financing (the “Effective Price”) less (B) 1,037,053 and all Additional Shares issued previously to the Holders pursuant to the Additional Issuance Rights. The CSIA includes a provision intended to limit our obligation to issue Additional Shares to the extent such Additional Shares would exceed the 20% limit on the number of shares that can be issued without shareholder approval pursuant to Section 713(a) of the NYSE MKT Company Guide.

Pursuant to Section 713(a) of the NYSE MKT Company Guide, shareholder approval is generally required prior to the issuance of common stock or common stock equivalents in connection with a transaction other than a public offering involving the sale, issuance, or potential issuance by the issuer of common stock or common stock equivalents equal to 20% or more of the outstanding shares of common stock as of immediately prior to the transaction for less than the greater of book or market value of the stock (the “NYSE 20% Cap”).

Any Additional Shares that we issue pursuant to the Additional Issuance Rights would be aggregated with the 853,465 shares of common stock issued to the Holders on April 8, 2016 pursuant to the CSIA for purposes of determining whether the total number of Additional Shares to be issued would equal or exceed the NSYE 20% Cap. Accordingly, absent shareholder approval, the maximum number of Additional Shares that we can issue pursuant to Section 713(a) of the NYSE MKT Company Guide without shareholder approval is 323,235 shares. We agreed to seek shareholder approval at our 2016 Annual Meeting of Shareholders (the “annual meeting”) of the issuance by us to the Holders of up to an aggregate of 1,037,053 shares of common stock as and to the extent required pursuant to the CSIA (the “Proposal”). If the shareholders do not approve the Proposal at the annual meeting, then in lieu of issuing any Additional Shares that would have been required to be issued to a Holder pursuant to the operation of the Additional Issuance Rights but for the limitations imposed by NYSE 20% Cap (the “Excess Shares”), we will, to the extent legally permitted, pay to such Holder a cash amount per Excess Share equal to the difference between the lowest price per share paid by investors in such Dilutive Financing and $4.05, less any cash payment per share previously made to such Holder pursuant to the CSIA (the “Cash Make-Whole”).

| 33

Shareholders will incur dilution of their percentage ownership interest in our common stock to the extent we issue Additional Shares to the Holders pursuant to the Additional Issuance Rights. Shareholders will incur greater ownership interest dilution to the extent the Proposal is approved and we become required to issue some or all of the 1,037,053 Additional Shares. In addition, because the Additional Shares will be issued for no additional consideration, any such issuance would reduce our net tangible book value per share. However, to the extent Additional Shares are not issued when otherwise required by the CSIA due to the NYSE 20% Cap, any payments by us in satisfaction of the Cash Make-Whole would also reduce our net tangible book value per share of as well as our overall net tangible book value.

If the Cash Make-Whole would be triggered by a proposed Dilutive Financing, the potential payment obligations could make such Dilutive Financing less feasible and financially viable for us, particularly if the proceeds to be received by us in such financing would not significantly exceed the Cash Make-Whole payments, and thereby jeopardize our ability to raise capital in a Dilutive Financing that could otherwise provide us with needed cash resources. Even if we are able to complete a Dilutive Financing, any Cash Make-Whole payments would deplete our cash resources at a time when our cash resources are limited.

There can be no assurance of whether the Proposal will be approved at the annual meeting. Any issuance or potential issuance of Additional Shares and/or payment or potential payment of Cash Make-Whole payments could adversely affect our stock price, make it more difficult for us to raise capital, and have a material adverse effect on our business, results of operations and financial condition.

A significant number of shares of our common stock are subject to issuance upon exercise or conversion of outstanding warrants, options and convertible securities, which upon such exercise or conversion may result in dilution to our security holders.*

As of March 31, 2016, we had outstanding warrants to purchase 1,379,649 shares of our common stock at an average exercise price of $9.34 per share, and outstanding options to purchase 872,977 shares of our common stock at an average exercise price of $7.29 per share. The exercise price and/or the number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances, including certain issuances of securities at a price equal to or less than the then current exercise price, subdivisions and stock splits, stock dividends, combinations, reorganizations, reclassifications, consolidations, mergers or sales of properties and assets and upon the issuance of certain assets or securities to holders of our common stock, as applicable. Although we cannot determine when these warrants or options will ultimately be exercised, it is reasonable to assume that such warrants and options will be exercised only if the exercise price is below the market price of our common stock. To the extent any of our outstanding warrants or options are exercised, additional shares of our common stock will be issued that will generally be eligible for resale in the public market (subject to limitations under Rule 144 under the Securities Act with respect to shares held by our affiliates), which will result in dilution to our security holders. The issuance of additional securities could also have an adverse effect on the market price of our common stock.

Our principal stockholders and management beneficially own a majority of our stock and will be able to exert significant control over matters subject to stockholder approval. *

As of March 31, 2016, our executive officers, directors, principal stockholders and their affiliates beneficially owned a majority of our outstanding voting stock. Therefore, these stockholders will have the ability to influence us through this ownership position. These stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders, acting together, may be able to control elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets, or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may believe are in your best interest as one of our stockholders.

Provisions of Washington law and our current articles of incorporation and bylaws may discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our current management.*

Provisions of Washington law and our current articles of incorporation and bylaws may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or remove our board of directors. These provisions include:

| · | authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;
| · | providing for a classified board of directors with staggered terms;
| · | requiring supermajority stockholder voting to effect certain amendments to our articles of incorporation and bylaws; and
| · | establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.

| 34

In addition, because we are incorporated in Washington, we are governed by the provisions of Chapter 23B.19 of the Washington Business Corporation Act, which, among other things, restricts the ability of stockholders owning 10% or more of our outstanding voting stock from merging or combining with us. These provisions could discourage potential acquisition attempts and could reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would without these provisions.

Although we believe these provisions collectively provide for an opportunity to receive higher bids by requiring potential acquirors to negotiate with our board of directors, they would apply even if an offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management.

We have never paid dividends on our common stock, and we do not anticipate paying any cash dividends on our common stock in the foreseeable future.*

We have never declared or paid cash dividends on our common stock. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of gain for the foreseeable future.

Maintaining and improving our financial controls and the requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act and the rules of the NYSE MKT. The requirements of these rules and regulations increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and place strain on our personnel, systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and financial condition.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. Ensuring that we have adequate internal financial and accounting controls and procedures in place is a costly and time-consuming effort that needs to be re-evaluated frequently.

We currently do not have an internal audit group, and we may need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. Implementing any appropriate changes to our internal controls may require specific compliance training for our directors, officers and employees, entail substantial costs to modify our existing accounting systems, and take a significant period of time to complete. Such changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent fraud.

In accordance with NYSE MKT rules, we are required to maintain a majority independent board of directors. The various rules and regulations applicable to public companies make it more difficult and more expensive for us to maintain directors’ and officers’ liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to maintain coverage. If we are unable to maintain adequate directors’ and officers’ insurance, our ability to recruit and retain qualified officers and directors will be significantly curtailed.

If securities or industry analysts do not publish research or publish unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We currently have three securities analysts and may never obtain additional research coverage by other securities and industry analysts. If no additional securities or industry analysts commence coverage of our company, the trading price for our stock could be negatively impacted. If we obtain additional securities or industry analyst coverage and if one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We are an “emerging growth company” and we cannot be certain if the reduced disclosure requirements applicable to “emerging growth companies” will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined under the JOBS Act. For so long as we are an “emerging growth company,” we intend to take advantage of certain exemptions from reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

| 35

We could be an “emerging growth company” for up to five years, although we may lose such status earlier, depending on the occurrence of certain events. We will remain an “emerging growth company” until the earliest to occur of (i) the last day of the fiscal year (a) following the fifth anniversary of our initial public offering conducted after we became a reporting company under the Exchange Act pursuant to our registration statement on Form 10 (File No. 000-23930), (b) in which we have total annual gross revenue of at least $1.0 billion or (c) in which we are deemed to be a “large accelerated filer” under the Exchange Act, which means that the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30th of the prior year, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We cannot predict if investors will find our common stock less attractive or our company less comparable to certain other public companies because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

Under the JOBS Act, “emerging growth companies” can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not “emerging growth companies.”

Sales of a substantial number of shares of our common stock in the public market by our existing stockholders could cause our stock price to decline.*

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

Certain holders of our common stock are entitled to rights with respect to the registration of their shares under the Securities Act. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by our affiliates as defined in Rule 144 under the Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

In Amendment No. 1 to Schedule 13D filed with the Securities and Exchange Commission by Third Security on April 15, 2016, Third Security and its affiliates, including NRM and Intrexon Corporation, declared their intention to liquidate their holdings in our equity securities. The timing and actual liquidation of securities by such persons is subject to compliance with applicable law. Furthermore, such declaration is not binding upon Third Security and its affiliates and thus such liquidation may never occur.

Future sales and issuances of our common stock or rights to purchase common stock by us, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to decline.

We expect that significant additional capital will be needed in the future to continue our planned operations, including conducting clinical trials, commercialization efforts, expanded research and development activities and costs associated with operating as a public company. To the extent we raise additional capital by issuing equity or convertible securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.

Only shareholders of record at the close of business on May 20, 2016 will be entitled to vote at the annual meeting. On this record date, there were 8,242,528 shares of common stock outstanding and entitled to vote.

#### Shareholder of Record: Shares Registered in Your Name

If on May 20, 2016 your shares were registered directly in your name with AmpliPhi’s transfer agent, Computershare, Inc., then you are a shareholder of record. As a shareholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

#### Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on May 20, 2016 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the shareholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.

## What am I voting on?

There are seven matters scheduled for a vote:

| • | Election of the four nominees for director named in this proxy statement, consisting of two Class I directors, one Class II director and one Class III director, to hold office until our 2019 Annual Meeting of Shareholders, 2017 Annual Meeting of Shareholders and 2018 Annual Meeting of Shareholders, respectively;

| • | Ratification of the Audit Committee’s selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2016.

## What if another matter is properly brought before the meeting?

The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

## How do I vote?

You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting.

The procedures for voting are fairly simple:

#### Shareholder of Record: Shares Registered in Your Name

If you are a shareholder of record, you may vote in person at the annual meeting, vote by proxy over the telephone, vote by proxy using the enclosed proxy card or vote by proxy through the internet. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy.

| • | To vote in person, come to the annual meeting and we will give you a ballot when you arrive.

| • | To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.

| • | To vote over the telephone, dial toll-free 1-800-652-8683 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Eastern Time on June 19, 2016 to be counted.

| • | To vote through the internet, go to www.envisionreports.com/APHB to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Eastern Time on June 19, 2016 to be counted.

#### Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a voting instruction form with these proxy materials from that organization rather than from AmpliPhi. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote in

person at the annual meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

## How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you owned as of the close of business on May 20, 2016.

## What happens if I do not vote?

#### Shareholder of Record: Shares Registered in Your Name

If you are a shareholder of record and do not vote by completing your proxy card, by telephone, through the internet or in person at the annual meeting, your shares will not be voted.

#### Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are matters that may substantially affect the rights or privileges of shareholders, such as mergers, shareholder proposals, elections of directors (even if not contested), and certain corporate governance proposals, even if management-supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1, 2, 3, 4, 5 or 6 without your instructions, but may vote your shares on Proposal 7 even in the absence of your instruction.

## What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable: “For” Proposal 1, the election of all four nominees for director; “For” Proposal 2, approval of the AmpliPhi 2016 Equity Incentive Plan; “For” Proposal 3, approval of the AmpliPhi 2016 Employee Stock Purchase Plan; “For” Proposal 4, approval of the Company’s reincorporation in the State of Delaware; “For” Proposal 5, approval of the issuance by the Company of up to an aggregate of 1,037,053 shares of common stock, as and to the extent required to be issued pursuant to a certain Common Stock Issuance Agreement; “For” Proposal 6, approval of the issuance by the Company of up to an aggregate of 4,706,000 shares of common stock and/or warrants to purchase common stock in a non-public financing for gross sale proceeds of up to $12,000,000 and at a discount to the then-current market value of the common stock not to exceed 15%; and “For” Proposal 7, ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

## Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees and Georgeson LLC may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies, Georgeson LLC will be paid its customary fee of approximately $10,000, plus out-of-pocket expenses if it solicits proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

3

## What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

## Can I change my vote after submitting my proxy?

#### Shareholder of Record: Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

| • | You may submit another properly completed proxy card with a later date.

| • | You may grant a subsequent proxy by telephone or through the internet.

| • | You may send a timely written notice that you are revoking your proxy to our Secretary at AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

| • | You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or internet proxy is the one that is counted.

#### Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

## When are shareholder proposals and director nominations due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by January 23, 2017, to our Secretary at AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

If Proposal 4 is approved at the annual meeting and we reincorporate in the State of Delaware, and if you wish to submit a proposal (including a director nomination) that is not to be included in next year’s proxy materials, your proposal generally must be submitted in writing to the same address no later than March 22, 2017 but no earlier than February 20, 2017. Please review our bylaws to be adopted if Proposal 4 is approved at the annual meeting, attached as Appendix E to this proxy statement, which contain additional requirements regarding advance notice of shareholder proposals and nominations.

If Proposal 4 is not approved at the annual meeting, and you wish to submit a proposal (including a director nomination) that is not to be included in next year’s proxy materials, your proposal generally must be submitted in writing to the same address not fewer than 60 nor more than 90 days prior to the date approved by the Board of Directors to hold the 2017 Annual Meeting of Shareholders; provided, that if we provide less than 60 days’ notice of such date, your proposal (including a director nomination) must be received by our Secretary not later than the tenth day following the day on which the notice of the date of the 2017 Annual Meeting of Shareholders is mailed or publicly disclosed. Please review our current bylaws, which contain additional requirements regarding advance notice of shareholder proposals and nominations.

## How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and, with respect to other proposals, votes “For” and “Against,” abstentions and, if applicable, broker non-votes. Under the rules of the NYSE MKT, abstentions are considered to be votes “cast” and will have the same effect as “Against” votes for each of Proposals 2, 3, 4, 5, 6 and 7. Broker non-votes will not be counted towards the vote total for any proposal, except Proposal 4, for which broker non-votes will have the same effect as “Against” votes.

4

## What are “broker non-votes”?

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the New York Stock Exchange to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

## How many votes are needed to approve each proposal?

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

Proposal Number |  | Proposal Description |  | Vote Required for Approval |  | Effect of Abstentions |  | Effect of Broker Non-Votes

## What is the quorum requirement?

A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if shareholders holding at least a majority of the outstanding shares entitled to vote on a matter and be counted collectively upon such matter are present at the meeting in person or represented by proxy. On the record date, there were 8,242,528 shares outstanding and entitled to vote. Thus, the holders of 4,121,265 shares must be present in person or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares at the meeting in person or represented by proxy may adjourn the meeting to another date.

## How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the annual meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

# Proposal 1
Election Of Directors

AmpliPhi’s Board of Directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Under our current bylaws, any vacancy occurring on the Board (other than a director removed for cause by the shareholders) may be filled by the shareholders, the Board or, if the directors in office constitute fewer than a quorum, by the affirmative vote of a majority of the remaining directors. A vacancy occurring as a result of the removal of a director for cause may be filled only by a vote of the holders of two-thirds of the shares then entitled to elect the director removed.

The Board of Directors presently has seven members. There are two directors in Class I, whose term of office expires in 2016. The two nominees for Class I director are Louis Drapeau and Michael S. Perry, Ph.D. Each of the Class I director nominees is currently a director of the Company who was previously elected by the shareholders. If elected at the annual meeting, each of these Class I director nominees would serve until the 2019 Annual Meeting of Shareholders and until his successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal.

Pursuant to Washington law and our current bylaws, the term of a director elected by the Board to fill a vacancy expires at the next shareholders' meeting at which directors are elected, regardless of whether the term of any other directors in the same class expire at a later date. Vijay Samant and Paul C. Grint, M.D. were elected by the Board in November 2015 to serve as a Class II director and a Class III director, respectively. Consequently, Mr. Samant’s and Dr. Grint’s term of office will expire at the annual meeting.

If elected at the annual meeting, Mr. Samant will serve as a director until the 2017 Annual Meeting of Shareholders and until his successor has been duly elected and qualified, or until his earlier death, resignation or removal.

If elected at the annual meeting, Dr. Grint will serve as a director until the 2018 Annual Meeting of Shareholders and until his successor has been duly elected and qualified, or until his earlier death, resignation or removal.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. Accordingly, the four nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the four nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by the Board of Directors. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that any nominee will be unable to serve.

# The Board of Directors Recommends
a Vote “for” Each Named Nominee

The Nominating and Corporate Governance Committee seeks to assemble a Board of Directors that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company’s business. To that end, the Nominating and Corporate Governance Committee has identified and evaluated nominees in the broader context of the Board of Directors’ overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the Nominating and Corporate Governance Committee views as critical to effective functioning of the Board of Directors. The brief biographies below include information regarding the specific and particular experience, qualifications, attributes or skills of each nominee that led the Nominating and Corporate Governance Committee to recommend that person as a nominee. However, each of the members of the Nominating and Corporate Governance Committee may have a variety of reasons why he believes a particular person would be an appropriate nominee for the Board of Directors, and these views may differ from the views of other members.

# INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

## Independence of The Board of Directors

As required under the NYSE MKT listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by the Board of Directors. Our Board of Directors consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of NYSE MKT, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that all of our directors are independent directors within the meaning of the applicable NYSE MKT listing standards, other than Mr. Salka and Ms. Johnson. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company. The Board concluded that Mr. Salka and Ms. Johnson are not independent directors within the meaning of the applicable NYSE MKT listing standards rules given their roles as Chief Executive Officer and Interim Chief Operating Officer, respectively.

## Board Leadership Structure

Our Board of Directors has a Chairman, Jeremy Curnock Cook, who has authority, among other things, to call and preside over board meetings, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board of Directors. We have a separate chair for each committee of the Board. As a general policy, the Board believes that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board of Directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board of Directors as a whole. As such, Mr. Salka serves as our Chief Executive Officer while Mr. Cook serves as our Chairman of the Board of Directors but is not an officer. We expect and intend the positions of Chairman of the Board of Directors and Chief Executive Officer to continue to be held by separate individuals in the future.

## Role of the Board in Risk Oversight

The Audit Committee of our Board of Directors is primarily responsible for overseeing our financial risk management processes on behalf of the Board. Going forward, we expect that the Audit Committee will receive reports from management at least quarterly regarding our assessment of risks. In addition, the audit Committee reports regularly to the full Board, which also considers our risk profile. The Audit Committee and the Board focus on the most significant risks we face and our general risk management strategies. While the Board oversees our risk management, our management is responsible for day-to-day risk management processes. The Board expects management to consider risk and risk management in each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted by the Audit Committee and the Board. We believe this division of responsibilities is the most effective approach for addressing the risks we face and that our board of directors leadership structure, which also emphasizes the independence of our board of directors in its oversight of its business and affairs, supports this approach.

## Meetings of The Board of Directors

The Board of Directors met eight times during the last fiscal year. Each Board member attended 75% or more of the total number of meetings of the Board and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member.

As required under applicable NYSE MKT listing standards, during 2015, the Company’s independent directors met on a regular basis in executive session without the presence of non-independent directors and management.

## Audit Committee

The Audit Committee of the Board of Directors was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. The functions of this Audit Committee include, among other things:

| • | reviewing our annual and quarterly financial statements and reports, including the disclosures contained under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and discussing the statements and reports with our independent auditors and management;

12

| • | reviewing on a periodic basis our investment policy; and

| • | reviewing and evaluating on an annual basis its own performance, including its compliance with its charter.

Our Audit Committee consists of Louis Drapeau, Michael S. Perry and Vijay Samant. The Board of Directors reviews the NYSE MKT listing standards definition of independence for Audit Committee members on an annual basis and has determined that each of the members of our Audit Committee satisfies the NYSE MKT listing requirements and SEC independence requirements. Mr. Drapeau serves as the chair of our Audit Committee.

Our Board of Directors has determined that Mr. Drapeau qualifies as an Audit Committee financial expert within the meaning of SEC regulations. In making this determination, our Board of Directors has considered Mr. Drapeau’s formal education and previous and current experience in financial roles. Both our independent registered public accounting firm and management periodically meet privately with our Audit Committee.

The Audit Committee charter can be found on our website at www.ampliphibio.com/corporate-governance.htm.

## Compensation Committee

Our Compensation Committee consists of Jeremy Curnock Cook, Paul C. Grint and Michael S. Perry. Dr. Perry serves as the chair of our Compensation Committee. Our Board of Directors has determined that each of the members of our Compensation Committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act, as defined pursuant to Section 162(m) of the Code, and satisfies the NYSE MKT listing independence requirements. The functions of this committee include, among other things:

| • | preparing the report that the SEC requires in our annual proxy statement; and

| • | reviewing and assessing on an annual basis its own performance.

#### Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other

14

background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer and Interim Chief Operating Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his or her compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the compensation committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and NYSE MKT, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

Historically, the Compensation Committee has made most of the significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, if any, including analyses of executive and director compensation paid at other companies identified by the consultant.

The Compensation Committee charter can be found on our website at www.ampliphibio.com/corporate-governance.htm.

## Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee of the Board of Directors is responsible for, among other things:

| • | identifying, reviewing and evaluating candidates to serve on our Board of Directors consistent with criteria approved by our Board of Directors;

| • | evaluating director performance on management and the board and applicable committees of the board and determining whether continued service on our Board of Directors is appropriate;

| • | evaluating, nominating and recommending individuals for membership on our Board of Directors;

| • | evaluating nominations by shareholders of candidates for election to our Board of Directors;

| • | considering and assessing the independence of members of our Board of Directors;

15

| • | developing a set of corporate governance policies and principles, periodically reviewing and assessing these policies and principles and their application and recommending to our Board of Directors any changes to such policies and principles;

| • | reviewing the adequacy of its charter on an annual basis; and

| • | annually evaluating the performance of the Nominating and Corporate Governance Committee.

Our Nominating and Corporate Governance Committee consists of Jeremy Curnock Cook, Louis Drapeau and Michael S. Perry. Our Board of Directors has determined that each of the members of this committee satisfies the NYSE MKT listing independence requirements. Mr. Curnock Cook serves as the chair of our Nominating and Corporate Governance Committee.

The Nominating and Corporate Governance Committee believes that candidates for director should, both individually and collectively, have the integrity, experience, judgment, commitment (including having sufficient time to devote to us and a sufficient level of participation), skills, diversity and expertise appropriate for our company. In assessing the directors, both individually and collectively, the Nominating and Corporate Governance Committee may consider our current needs and the needs of our Board of Directors, to maintain a balance of knowledge, experience and capability in various areas. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for NYSE MKT purposes, which determination is based upon applicable NYSE MKT listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by shareholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the criteria set forth above, based on whether or not the candidate was recommended by a shareholder. Shareholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Secretary of the Company at 3579 Valley Centre Drive, San Diego, California 92130, no later than the close of business on the 90th day and no earlier than the 120th day prior to the one year anniversary of the preceding year’s annual meeting of shareholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and the number of shares of the Company’s stock that are owned beneficially by such nominating shareholder as of the date the submission is made. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

The Nominating and Corporate Governance Committee charter can be found on our website at www.ampliphibio.com/corporate-governance.html.

## Shareholder Communications With The Board Of Directors

The Company’s Board has adopted a formal process by which shareholders may communicate with the Board or any of its directors. Shareholders who wish to communicate with the Board may do so by sending written communications addressed to the Secretary of the Company at AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130. All communications will be compiled by the Secretary of the Company and submitted to the Board of Directors or the individual directors on a periodic basis. These communications will be reviewed by the Company’s Secretary, who will determine whether the communication should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and

16

hostile communications). All communications directed to the Audit Committee in accordance with the Company’s Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters, discussed below, will be treated in accordance with that policy.

Any interested person may, however, communicate directly with the presiding director or the independent directors as a group. Persons interested in communicating directly with the independent directors regarding their concerns or issues may do so by addressing correspondence to a particular director, or to the independent directors generally, in care of AmpliPhi Biosciences Corporation at 3579 Valley Centre Drive, Suite 100, San Diego, California 92130. If no particular director is named, letters will be forwarded, depending upon the subject matter, to the Chair of the Audit, Compensation, or Nominating and Corporate Governance Committee.

## Code of Ethics

We have adopted a code of ethics for directors, officers (including our principal executive officer, principal financial officer and principal accounting officer) and employees, known as the Code of Business Conduct and Ethics. The Code of Business Conduct and Ethics is available on our website at http://www.ampliphibio.com under the Corporate Governance section of our Investor Relations page. We will promptly disclose on our website (i) the nature of any amendment to the policy that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions and (ii) the nature of any waiver, including an implicit waiver, from a provision of the policy that is granted to one of these specified individuals that is required to be disclosed pursuant to SEC rules and regulations, the name of such person who is granted the waiver and the date of the waiver.

## Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters

We have adopted an Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters to facilitate the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, as well as the confidential, anonymous submission by our employees of concerns regarding these matters. The Open Door Policy is available on our website at http://www.ampliphibio.com/corporate-governance.html.

# Proposal 2
Approval of the
AmpliPhi Biosciences Corporation 2016 Equity Incentive Plan

## Overview

On April 21, 2016, our Board of Directors approved our AmpliPhi Bioscience Corporation 2016 Equity Incentive Plan, or the 2016 Plan, subject to approval by our shareholders at the Annual Meeting. The 2016 Plan is intended as the successor plan to our 2013 Stock Incentive Plan, or 2013 Plan. If this Proposal 2 is approved, no additional equity grants may be made under the 2013 Plan.

## Requested Shares

Subject to adjustment for certain changes in our capitalization, the aggregate number of shares of our common stock that may be issued under the 2016 Plan will not exceed the sum of (i) the number of unallocated shares remaining available for the grant of new awards under the 2013 Plan as of the effective date of the 2016 Plan (which is equal to 514,340 shares as of May 20, 2016), (ii) 1,000,000 new shares, and (iii) any Prior Plans’ Returning Shares (as defined below in “Description of the 2016 Plan — Share Reserve”), as such shares become available from time to time.

Approval of the 2016 Plan by our shareholders will allow us to grant stock options and other equity awards at levels determined appropriate by our Board of Directors or Compensation Committee. The 2016 Plan will also allow us to utilize a broad array of equity incentives and performance cash incentives in order to secure and retain the services of our employees, directors and consultants, and to provide long-term incentives that align the interests of our employees, directors and consultants with the interests of our shareholders.

## Why You Should Vote For the 2016 Plan

### Key Plan Features

The 2016 Plan includes provisions that are designed to protect our shareholders’ interests including:

| • | No single trigger accelerated vesting upon change in control. The 2016 Plan does not provide for any automatic mandatory vesting of awards upon a change in control.

| • | Awards subject to forfeiture/clawback. Awards granted under the 2016 Plan will be subject to recoupment in accordance with any clawback policy that we are required to adopt pursuant to the listing standards of any national securities exchange or association on which our securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, we may impose other clawback, recovery or recoupment provisions in an award agreement, including a reacquisition right in respect of previously acquired shares or other cash or property upon the occurrence of cause.

| • | No discounted stock options or stock appreciation rights. All stock options and stock appreciation rights granted under the 2016 Plan must have an exercise or strike price equal to or greater than the fair market value of our common stock on the date the stock option or stock appreciation right is granted.

| • | Administration by independent committee. The 2016 Plan will be administered by the members of our Compensation Committee, all of whom are “non-employee directors” within the meaning of Rule 16b-3 under the Exchange Act and “outside directors” within the meaning of Section 162(m) of the Code.

| • | Material amendments require shareholder approval. The 2016 Plan requires shareholder approval of any material revisions to the 2016 Plan.

18

| • | Limit on non-employee director awards and other awards. As further described below, except in extraordinary circumstances, the maximum number of shares subject to stock awards granted during any calendar year to any of our non-employee directors, taken together with any cash fees paid by the Company to such non-employee director during such calendar year, may not generally exceed $375,000 in total value (calculating the value of any such stock awards based on the grant date fair value of such stock awards for financial reporting purposes), or with respect to the calendar year in which the non-employee director is first appointed or elected, $783,000 in total value. The 2016 Plan also contains other annual per-participant limits on stock options, stock appreciation rights and performance-based stock and cash awards.

### We Intend to Recruit Additional Personnel to Facilitate the Growth of Our Business and Equity Awards Are an Important Part of Our Compensation Philosophy

The Board of Directors believes that the future success of the Company depends, in large part, upon the ability of the Company to implement our plans for future expansion and growth in light of our anticipated recruiting and retention needs and is necessary to maintain a competitive position in recruiting, retaining and motivating key personnel, consultants and advisors. The Board of Directors believes that the issuance of equity awards is a key element underlying our ability to recruit, retain and motivate key personnel, consultants and advisors, better aligns the interests of such persons with those of our shareholders, and is a substantial contributing factor to our success and the future growth of our business. Therefore, the Board of Directors believes that the approval of the 2016 Plan is in the best interests of the Company and its shareholders and recommends a vote in favor of this proposal.

If this Proposal 2 is adopted by our shareholders, the 2016 Plan will become effective upon the date of the Annual Meeting and no additional equity grants maybe made under our 2013 Plan. In the event that our shareholders do not approve this Proposal 2, the 2016 Plan will not become effective and our 2013 Plan will continue in its current form. However, we believe that the shares available for grant under the 2013 Plan will be insufficient to meet our anticipated recruiting and retention needs.

### We Manage Our Equity Award Use Carefully and Our Dilution Is Reasonable

We manage our long-term shareholder dilution by limiting the number of equity awards granted annually. The Compensation Committee monitors our annual burn rate, dilution, and equity expense to ensure that we maximize shareholders’ value by granting only the appropriate number of equity awards necessary to recruit, reward, and retain key personnel, consultants and advisors.

The following table provides certain additional information regarding our equity award program.

|  | As of December 31, 2015
Total shares subject to outstanding stock options |  |  | 669,769 |
Total shares subject to full value awards |  |  | — |
Weighted-average exercise price per share of outstanding stock options |  | $ | 8.68 |
Weighted-average remaining term of outstanding stock options |  |  | 9.29 yrs |
Total shares available for grant under the 2013 Plan |  |  | 723,431 |
Total shares available for grant under other equity plans |  |  | — |

|  | As of May 20, 2016 (Record Date)
Total common stock outstanding |  |  | 8,242,528 |
Closing price of common stock as reported on The NYSE MKT |  | $ | 1.57 |

Common measures of an equity incentive plan’s cost include burn rate, dilution and overhang. The burn rate, or run rate, refers to how fast a company uses the supply of shares authorized for issuance under its equity incentive plan. Over the last three years, the Company has maintained an average equity run rate of 5.6% of shares of common stock outstanding per year, including shares of preferred stock on an as-converted basis. Our run rate in 2015 was unusually high due primarily to the equity grant that we made to Mr. Salka in

19

connection with his commencement of our Chief Executive Officer, which the Compensation Committee believed was consistent with the level of options granted to chief executive officers in our industry. Excluding the special hiring grant we made to our Chief Executive Officer, in 2015 our three-year average equity run rate was 3.7%. Dilution measures the degree to which our stockholders' ownership has been diluted by stock-based compensation awarded under our equity incentive plans and also includes shares that may be awarded under our equity incentive plans in the future (“overhang”).

The following table shows how our key equity metrics have changed over the past three years:

Key Equity Metrics |  | 2013 |  | 2014 |  | 2015(4)
Equity Run Rate(1) |  |  | 7.9 | % |  |  | 0.3 | % |  |  | 8.5 | %
Overhang(2) |  |  | 24.0 | % |  |  | 21.6 | % |  |  | 18.9 | %
Dilution(3) |  |  | 9.2 | % |  |  | 7.7 | % |  |  | 9.1 | %

| (1) | Equity run rate is calculated by dividing the number of shares subject to equity awards granted during the year by the weighted-average number of common shares and as-converted preferred shares outstanding during the year.

| (2) | Overhang is calculated by dividing (a) the sum of (x) the number of shares subject to equity awards outstanding at the end of the year and (y) the number of shares available for future grants, by (b) the number of common shares and as-converted preferred shares outstanding at the end of the year.

| (3) | Dilution is calculated by dividing the number of shares subject to equity awards outstanding at the end of the fiscal year by the number of common shares and as-converted preferred shares outstanding at the end of the fiscal year.

| (4) | Excluding the special stock option grant we made to Mr. Salka in connection with his commencement of employment with us, the 2015 Equity Run Rate was 2.8%, Overhang was 13.4% and Dilution was 3.7%.

In evaluating whether to approve the 2016 Plan our Board of Directors and Compensation Committee reviewed our historical issuances under our 2013 Plan and considered our future needs for equity awards under the 2016 Plan, based on our plans for future expansion and growth in light of our anticipated recruiting and retention needs and potential changes in company capitalization and dilution. We intend to grant future equity awards under the 2016 Plan in amounts that are reasonable and based on market data prepared by the independent compensation consultant to the Compensation Committee. If this Proposal 2 is approved by our shareholders, we expect the initial share reserve to last for approximately 2 to 3 years of awards. While we believe this is a reasonable estimate of how long the share reserve could last, because there are a number of uncertain factors that could impact our future share usage, we are not able to presently forecast the share amounts and rate at which we will utilize equity as a tool for attracting and retaining talent.

### Continued Ability to Grant Performance-Based Awards

Approval of the 2016 Plan by our shareholders will also constitute approval of terms and conditions set forth therein that will permit us to grant stock options, stock appreciation rights and performance-based stock and cash awards under the 2016 Plan that may qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code. Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended, or the Code, disallows a deduction to any publicly held corporation and its affiliates for certain compensation paid to “covered employees” in a taxable year to the extent that compensation to a covered employee exceeds $1 million. However, some kinds of compensation, including qualified “performance-based compensation,” are not subject to this deduction limitation. For compensation awarded under a plan to qualify as “performance-based compensation” under Section 162(m) of the Code, among other things, the following terms must be disclosed to and approved by the shareholders before the compensation is paid: (i) a description of the employees eligible to receive such awards; (ii) a per-person limit on the number of shares subject to stock options, stock appreciation rights and performance-based stock awards, and the amount of cash subject to performance-based cash awards, that may be granted to any employee under the plan in any year; and (iii) a description of the business criteria upon which the performance goals for performance-based awards may be granted (or become vested or exercisable). Accordingly, we are requesting that our shareholders approve the 2016 Plan, which includes terms and conditions regarding eligibility for awards, annual

20

per-person limits on awards and the business criteria for performance-based awards granted under the 2016 Plan (as described in the summary below).

We believe it is in the best interests of our Company and our shareholders to preserve the ability to grant “performance-based compensation” under Section 162(m) of the Code. However, in certain circumstances, we may determine to grant compensation to covered employees that is not intended to qualify as “performance-based compensation” for purposes of Section 162(m) of the Code. Moreover, even if we grant compensation that is intended to qualify as “performance-based compensation” for purposes of Section 162(m) of the Code, we cannot guarantee that such compensation ultimately will be deductible by us.

### Description of 2016 Plan

The material features of the 2016 Plan are outlined below. This summary is qualified in its entirety by reference to the complete text of the 2016 Plan. Shareholders are encouraged to read the actual text of the 2016 Plan, which is appended to this proxy statement as Appendix A and may be accessed from the SEC’s website at www.sec.gov.

Purpose. The 2016 Plan is critical to our ongoing effort to build shareholder value through recruiting, retaining and motivating employees, directors and consultants. We are seeking to approval of the 2016 Plan to provide for the shares necessary so that we can ensure that we have the most qualified, motivated employees possible to help us move the Company’s programs forward and implement our recruiting plans to facilitate the future growth of our business.

Awards. The 2016 Plan provides for the grant of incentive stock options, or ISOs, nonstatutory stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards, all of which may be granted to employees, including officers, non-employee directors and consultants of us and our affiliates. Additionally, the 2016 Plan provides for the grant of performance cash awards.

Eligibility. As of May 20, 2016, all of our approximately 30 employees, six non-employee directors and one consultant are eligible to participate in the 2016 Plan and may receive all types of awards other than ISOs. ISOs may be granted only to our employees (including officers) and employees of our affiliates.

Share Reserve. The aggregate number of shares of our common stock that initially may be issued pursuant to stock awards under the 2016 Plan will not exceed 2,373,000 shares, which is the sum of (i) 1,000,000 shares, plus (ii) the number of shares reserved for issuance under our 2013 Plan at the time our 2016 Plan became effective, plus (iii) any shares subject to stock options or other stock awards granted under our Prior Plans that would have otherwise returned to the share reserve of our Prior Plans (such as upon the expiration or termination of an option prior to exercise), such shares are referred to as our “Prior Plans’ Returning Shares.” Collectively, our 2013 Plan, 2009 Targeted Genetics Stock Incentive Plan and the AmpliPhi Biosciences Corporation 2012 Stock Incentive Plan are our “Prior Plans.”

Additionally, the number of shares of our common stock reserved for issuance under our 2016 Plan automatically increases on January 1 of each year, beginning on January 1, 2017 and continuing through and including January 1, 2026, by 5% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our Board of Directors. The maximum number of shares that may be issued upon the exercise of ISOs under our 2016 Plan is 4,746,000 shares.

If a stock award granted under the 2016 Plan expires or otherwise terminates without being exercised in full, or is settled in cash, the shares of our common stock not acquired pursuant to the stock award again will become available for subsequent issuance under the 2016 Plan. In addition, the following types of shares under the 2016 Plan may become available for the grant of new stock awards under the 2016 Plan: (1) shares that are forfeited to or repurchased by us prior to becoming fully vested; (2) shares withheld to satisfy income or employment withholding taxes; or (3) shares used to pay the exercise or purchase price of a stock award. Shares issued under the 2016 Plan may be previously unissued shares or reacquired shares bought by us on the open market.

21

Section 162(m) Limits. No person may be granted stock awards covering more than 1,000,000 shares of our common stock under our 2016 Plan during any calendar year pursuant to stock options, stock appreciation rights and other stock awards whose value is determined by reference to an increase over an exercise or strike price of at least 100% of the fair market value on the date the stock award is granted. Additionally, no person may be granted in a calendar year a performance stock award covering more than 1,000,000 shares or a performance cash award having a maximum value in excess of $2,000,000. Such limitations are designed to help assure that any deductions to which we would otherwise be entitled with respect to such awards will not be subject to the $1,000,000 limitation on the income tax deductibility of compensation paid to any covered executive officer imposed by Section 162(m) of the Code.

Non-Employee Director Compensation Limit. The aggregate value of all compensation paid or granted, as applicable, to any individual for service as a non-employee director of our Board of Directors with respect to any calendar year commencing with the 2016 calendar year, including awards granted under the 2016 Plan and cash fees paid by us to such non-employee director, will not exceed (i) $375,000 in total value or (ii) in the event such non-employee director is first appointed or elected to our Board of Directors during such calendar year, $783,000 in total value, in each case calculating the value of any awards granted under the 2016 Plan based on the grant date fair value of such awards for financial reporting purposes. However, the Board of Directors may make exceptions to the applicable limit for individual non-employee directors in extraordinary circumstances (for example, to compensate such individual for interim service in the capacity of an officer of the Company), as the Board of Directors may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation.

Administration. Our Board of Directors, or a duly authorized committee thereof, has the authority to administer the 2016 Plan. Our Board of Directors has delegated authority to administer the 2016 Plan to our Compensation Committee. Subject to the terms of the 2016 Plan, the Compensation Committee, referred to herein as the plan administrator, determines recipients, dates of grant, the numbers and types of stock awards to be granted and the terms and conditions of the stock awards, including the period of their exercisability and vesting schedule applicable to a stock award. Subject to the limitations set forth below, the plan administrator will also determine the exercise price, strike price or purchase price of awards granted and the types of consideration to be paid for the award.

The plan administrator has the authority to modify outstanding awards under our 2016 Plan. Subject to the terms of our 2016 Plan, the plan administrator has the authority to reduce the exercise, purchase or strike price of any outstanding stock award, cancel any outstanding stock award in exchange for new stock awards, cash or other consideration, or take any other action that is treated as a repricing under generally accepted accounting principles, with the consent of any adversely affected participant.

Stock Options. ISOs and NSOs are granted pursuant to stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for a stock option, within the terms and conditions of the 2016 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant. Options granted under the 2016 Plan vest at the rate specified by the plan administrator.

The plan administrator determines the term of stock options granted under the 2016 Plan, up to a maximum of 10 years. Unless the terms of an option holder’s stock option agreement provide otherwise, if an option holder’s service relationship with us, or any of our affiliates, ceases for any reason other than disability, death or cause, the option holder may generally exercise any vested options for a period of three months following the cessation of service. The option term may be extended in the event that exercise of the option following such a termination of service is prohibited by applicable securities laws or our insider trading policy. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability or death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, options generally terminate immediately upon the termination of the individual for cause. In no event may an option be exercised beyond the expiration of its term.

22

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO, and (5) other legal consideration approved by the plan administrator.

Unless the plan administrator provides otherwise, options generally are not transferable except by will, the laws of descent and distribution, or pursuant to a domestic relations order. An optionholder may designate a beneficiary, however, who may exercise the option following the optionholder’s death.

Tax Limitations on Incentive Stock Options. The aggregate fair market value, determined at the time of grant, of our common stock with respect to ISOs that are exercisable for the first time by an optionholder during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our affiliates unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Awards. Restricted stock awards are granted pursuant to restricted stock award agreements adopted by the plan administrator. Restricted stock awards may be granted in consideration for (1) cash, check, bank draft or money order, (2) services rendered to us or our affiliates, or (3) any other form of legal consideration. Common stock acquired under a restricted stock award may, but need not, be subject to a share repurchase option in our favor in accordance with a vesting schedule to be determined by the plan administrator. Rights to acquire shares under a restricted stock award may be transferred only upon such terms and conditions as set by the plan administrator. Except as otherwise provided in the applicable award agreement, restricted stock unit awards that have not vested will be forfeited upon the participant’s cessation of continuous service for any reason.

Restricted Stock Unit Awards. Restricted stock unit awards are granted pursuant to restricted stock unit award agreements adopted by the plan administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration. A restricted stock unit award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator, or in any other form of consideration set forth in the restricted stock unit award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by a restricted stock unit award. Except as otherwise provided in the applicable award agreement, restricted stock units that have not vested will be forfeited upon the participant’s cessation of continuous service for any reason.

Stock Appreciation Rights. Stock appreciation rights are granted pursuant to stock appreciation grant agreements adopted by the plan administrator. The plan administrator determines the strike price for a stock appreciation unit, which generally cannot be less than 100% of the fair market value of our common stock on the date of grant. Upon the exercise of a stock appreciation unit, we will pay the participant an amount equal to the product of (1) the excess of the per share fair market value of our common stock on the date of exercise over the strike price, multiplied by (2) the number of shares of common stock with respect to which the stock appreciation unit is exercised. A stock appreciation unit granted under the 2016 Plan vests at the rate specified in the stock appreciation grant agreement as determined by the plan administrator.

The plan administrator determines the term of stock appreciation rights granted under the 2016 Plan, up to a maximum of ten years. Unless the terms of a participant’s stock appreciation right agreement provides otherwise, if a participant’s service relationship with us or any of our affiliates ceases for any reason other than cause, disability or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. The stock appreciation right term may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. If a participant’s service relationship with us, or any of our affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for

23

cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. The 2016 Plan permits the grant of performance-based stock and cash awards that may qualify as performance-based compensation that is not subject to the $1,000,000 limitation on the income tax deductibility of compensation paid to a covered executive officer imposed by Section 162(m) of the Code. To help assure that the compensation attributable to performance-based awards will so qualify, our Compensation Committee can structure such awards so that stock or cash will be issued or paid pursuant to such award only after the achievement of certain pre-established performance goals during a designated performance period.

A performance stock award is a stock award that is payable (including that may be granted, may vest, or may be exercised) contingent upon the achievement of pre-determined performance goals during a performance period. A performance stock award may require the completion of a specified period of continuous service. The length of any performance period, the performance goals to be achieved during the performance period, and the measure of whether and to what degree such performance goals have been attained will generally be determined by our Compensation Committee, except that the plan administrator also may make any such determinations to the extent that the award is not intended to comply with Section 162(m) of the Code. In addition, to the extent permitted by applicable law and the performance stock award agreement, the plan administrator may determine that cash may be used in payment of performance stock awards.

A performance cash award is a cash award that is payable contingent upon the achievement of pre-determined performance goals during a performance period. A performance cash award may require the completion of a specified period of continuous service. The length of any performance period, the performance goals to be achieved during the performance period, and the measure of whether and to what degree such performance goals have been attained will generally be determined by our Compensation Committee, except that the plan administrator also may make any such determinations to the extent that the award is not intended to comply with Section 162(m) of the Code. The plan administrator may specify the form of payment of performance cash awards, which may be cash or other property, or may provide for a participant to have the option for his or her performance cash award, or such portion thereof as the plan administrator may specify, to be paid in whole or in part in cash or other property.

In granting a performance award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, our Compensation Committee will set a period of time, or a performance period, over which the attainment of one or more goals, or performance goals, will be measured. Within the time period prescribed by Section 162(m) of the Code (no later than the earlier of the 90th day of a performance period and the date on which 25% of the performance period has elapsed, and in any event at a time when the achievement of the performance goals remains substantially uncertain), our Compensation Committee will establish the performance goals, based upon one or more criteria, or performance criteria, enumerated in the 2016 Plan and described below. As soon as administratively practicable following the end of the performance period, our Compensation Committee will certify in writing whether the performance goals have been satisfied.

Performance goals under the 2016 Plan will be based on any one or more of the following performance criteria: (1) earnings (including earnings per share and net earnings); (2) earnings before interest, taxes and depreciation; (3) earnings before interest, taxes, depreciation and amortization; (4) earnings before interest, taxes, depreciation, amortization and legal settlements; (5) earnings before interest, taxes, depreciation, amortization, legal settlements and other income (expense); (6) earnings before interest, taxes, depreciation, amortization, legal settlements, other income (expense) and stock-based compensation; (7) earnings before interest, taxes, depreciation, amortization, legal settlements, other income (expense), stock-based compensation and changes in deferred revenue; (8) earnings before interest, taxes, depreciation, amortization, legal settlements, other income (expense), stock-based compensation, other non-cash expenses and changes in deferred revenue; (9) total shareholder return; (10) return on equity or average shareholder’s equity; (11) return on assets, investment, or capital employed; (12) stock price; (13) margin (including gross margin); (14) income (before or after taxes); (15) operating income; (16) operating income after taxes; (17) pre-tax profit; (18) operating cash flow; (19) sales or revenue targets; (20) increases in revenue or product revenue;

24

(21) expenses and cost reduction goals; (22) improvement in or attainment of working capital levels; (23) economic value added (or an equivalent metric); (24) market share; (25) cash flow; (26) cash flow per share; (27) cash balance; (28) cash burn; (29) cash collections; (30) share price performance; (31) debt reduction; (32) implementation or completion of projects or processes (including, without limitation, clinical trial initiation, clinical trial enrollment and dates, clinical trial results, regulatory filing submissions, regulatory filing acceptances, regulatory or advisory committee interactions, regulatory approvals, and product supply); (33) shareholders’ equity; (34) capital expenditures; (35) debt levels; (36) operating profit or net operating profit; (37) workforce diversity; (38) growth of net income or operating income; (39) billings; (40) bookings; (41) employee retention; (42) initiation of studies by specific dates; (43) budget management; (44) submission to, or approval by, a regulatory body (including, but not limited to the U.S. Food and Drug Administration) of an applicable filing or a product; (45) regulatory milestones; (46) progress of internal research or development programs; (47) acquisition of new customers; (48) customer retention and/or repeat order rate; (49) improvements in sample and test processing times; (50) progress of partnered programs; (51) partner satisfaction; (52) timely completion of clinical trials; (53) submission of 510(k)s or pre-market approvals and other regulatory achievements; (54) milestones related to research development (including, but not limited to, preclinical and clinical studies), product development and manufacturing; (55) expansion of sales in additional geographies or markets; (56) research progress, including the development of programs; (57) strategic partnerships or transactions (including in-licensing and out-licensing of intellectual property; and (58) and to the extent that an award is not intended to comply with Section 162(m) of the Code, other measures of performance selected by the plan administrator.

Performance goals may be based on a company-wide basis, with respect to one or more business units, divisions, affiliates or business segments, and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Under the 2016 Plan, unless specified otherwise by our Compensation Committee (or, if not required for compliance with Section 162(m) of the Code, the plan administrator) (i) in the award agreement at the time the award is granted or (ii) in such other document setting forth the performance goals at the time the performance goals are established, our compensation committee (or, if not required for compliance with Section 162(m) of the Code, the plan administrator) will appropriately make adjustments in the method of calculating the attainment of performance goals for a performance period: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to generally accepted accounting principles; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of any items that are “unusual” in nature or occur “infrequently” as determined under generally accepted accounting principles; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any business divested by the Company achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of common stock of the Company by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common shareholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under the Company’s bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under generally accepted accounting principles; (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under generally accepted accounting principles; and (12) to exclude the effects of the timing of acceptance for review and/or approval of submissions to the U.S. Food and Drug Administration or any other regulatory body. In addition, our Compensation Committee (or, if not required for compliance with Section 162(m) of the Code, the plan administrator) retains the discretion to reduce or eliminate the compensation or economic benefit due upon the attainment of any performance goals and to define the manner of calculating the performance criteria it selects to use for a performance period.

Other Stock Awards. The plan administrator may grant other awards based in whole or in part by reference to our common stock. The plan administrator will set the number of shares under the stock award and all other terms and conditions of such awards.

25

Changes to Capital Structure. In the event that there is a specified type of change in our capital structure, such as a stock split or recapitalization, appropriate adjustments will be made to (a) the class and maximum number of shares reserved for issuance under the 2016 Plan, (b) the class and maximum number of shares by which the share reserve may increase automatically each year, (c) the class and maximum number of shares that may be issued upon the exercise of ISOs, (d) the class and maximum number of shares subject to stock awards that can be granted in a calendar year (as established under the 2016 Plan pursuant to Section 162(m) of the Code) and (e) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions. In the event of certain specified significant corporate transactions, the plan administrator has the discretion to take any of the following actions with respect to stock awards:

| • | arrange for the assumption, continuation or substitution of a stock award by a surviving or acquiring entity or parent company;

| • | arrange for the assignment of any reacquisition or repurchase rights held by us to the surviving or acquiring entity or parent company;

| • | accelerate the vesting of the stock award and provide for its termination prior to the effective time of the corporate transaction;

| • | arrange for the lapse of any reacquisition or repurchase right held by us;

| • | cancel or arrange for the cancellation of the stock award in exchange for such cash consideration, if any, as our plan administrator may deem appropriate; or

| • | make a payment equal to the excess of (a) the value of the property the participant would have received upon exercise of the stock award over (b) the exercise price otherwise payable in connection with the stock award.

Our plan administrator is not obligated to treat all stock awards, even those that are of the same type, in the same manner.

Under the 2016 Plan, a corporate transaction is generally the consummation of (i) a sale or other disposition of all or substantially all of our consolidated assets, (ii) a sale or other disposition of at least 50% of our outstanding securities, (iii) a merger, consolidation or similar transaction following which we are not the surviving corporation, or (iv) a merger, consolidation or similar transaction following which we are the surviving corporation but the shares of our common stock outstanding immediately prior to such transaction are converted or exchanged into other property by virtue of the transaction.

Change of Control. The plan administrator may provide, in an individual award agreement or in any other written agreement between a participant and us that the stock award will be subject to additional acceleration of vesting and exercisability in the event of a change of control. Under the 2016 Plan, a change of control is generally (i) the acquisition by a person or entity of more than 50% of our combined voting power other than by merger, consolidation or similar transaction; (ii) a consummated merger, consolidation or similar transaction immediately after which our shareholders cease to own more than 50% of the combined voting power of the surviving entity; (iii) a consummated sale, lease or exclusive license or other disposition of all or substantially of our consolidated assets; (iv) a complete dissolution or liquidation; or (v) when a majority of the Board of Directors becomes comprised of individuals whose nomination, appointment, or election was not approved by a majority of the Board of Directors members or their approved successors.

Amendment and Termination. Our Board of Directors has the authority to amend, suspend, or terminate our 2016 Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. No ISOs may be granted after the tenth anniversary of the date our Board of Directors adopted our 2016 Plan.

## U.S. Federal Income Tax Consequences

The following is a summary of the principal United States federal income tax consequences to participants and us with respect to participation in the 2016 Plan. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside.

26

The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local and other tax consequences of the grant or exercise of an award or the disposition of stock acquired the 2016 Plan. The 2016 Plan is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974. Our ability to realize the benefit of any tax deductions described below depends on our generation of taxable income as well as the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of our tax reporting obligations.

#### Nonstatutory Stock Options

Generally, there is no taxation upon the grant of an NSO if the stock option is granted with an exercise price equal to the fair market value of the underlying stock on the grant date. Upon exercise, a participant will recognize ordinary income equal to the excess, if any, of the fair market value of the underlying stock on the date of exercise of the stock option over the exercise price. If the participant is employed by us or one of our affiliates, that income will be subject to withholding taxes. The participant’s tax basis in those shares will be equal to their fair market value on the date of exercise of the stock option, and the participant’s capital gain holding period for those shares will begin on that date. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant.

#### Incentive Stock Options

The 2016 Plan provides for the grant of stock options that are intended to qualify as “incentive stock options,” as defined in Section 422 of the Code. Under the Code, a participant generally is not subject to ordinary income tax upon the grant or exercise of an ISO. If the participant holds a share received upon exercise of an ISO for more than two years from the date the stock option was granted and more than one year from the date the stock option was exercised, which is referred to as the required holding period, the difference, if any, between the amount realized on a sale or other taxable disposition of that share and the participant’s tax basis in that share will be long-term capital gain or loss. If, however, a participant disposes of a share acquired upon exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the participant generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date of exercise of the stock option over the exercise price. However, if the sales proceeds are less than the fair market value of the share on the date of exercise of the stock option, the amount of ordinary income recognized by the participant will not exceed the gain, if any, realized on the sale. If the amount realized on a disqualifying disposition exceeds the fair market value of the share on the date of exercise of the stock option, that excess will be short-term or long-term capital gain, depending on whether the holding period for the share exceeds one year.

For purposes of the alternative minimum tax, the amount by which the fair market value of a share of stock acquired upon exercise of an ISO exceeds the exercise price of the stock option generally will be an adjustment included in the participant’s alternative minimum taxable income for the year in which the stock option is exercised. If, however, there is a disqualifying disposition of the share in the year in which the stock option is exercised, there will be no adjustment for alternative minimum tax purposes with respect to that share. In computing alternative minimum taxable income, the tax basis of a share acquired upon exercise of an ISO is increased by the amount of the adjustment taken into account with respect to that share for alternative minimum tax purposes in the year the stock option is exercised.

We are not allowed an income tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired upon exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant, subject to the requirement of reasonableness and the provisions of Section 162(m) of the Code, and provided that either the employee includes that amount in income or we timely satisfy our reporting requirements with respect to that amount.

#### Restricted Stock Awards

Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is not vested when it is received (for example, if the employee is required to work for a period of time in order to have the right to sell the stock), the recipient generally will not recognize income until the stock becomes vested, at which time the recipient will recognize ordinary income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the recipient in exchange for the stock. A recipient may, however, file an election with the Internal Revenue Service, within 30 days following his or her receipt of the stock award, to recognize ordinary income, as of the date the recipient receives the award, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the recipient for the stock.

The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock award will be the amount paid for such shares plus any ordinary income recognized either when the stock is received or when the stock becomes vested.

Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock award.

#### Restricted Stock Unit Awards

Generally, the recipient of a restricted stock unit award structured to conform to the requirements of Section 409A of the Code or an exception to Section 409A of the Code will recognize ordinary income at the time the stock is delivered equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. To conform to the requirements of Section 409A of the Code, the stock subject to a restricted stock unit award may generally only be delivered upon one of the following events: a fixed calendar date (or dates), separation from service, death, disability or a change in control. If delivery occurs on another date, unless the restricted stock unit award otherwise complies with or qualifies for an exception to the requirements of Section 409A of the Code, in addition to the tax treatment described above, the recipient will owe an additional 20% federal tax and interest on any taxes owed.

The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock unit award will be the amount paid for such shares plus any ordinary income recognized when the stock is delivered.

Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the restricted stock unit award.

#### Stock Appreciation Rights

Generally, if a stock appreciation right is granted with an exercise price equal to the fair market value of the underlying stock on the grant date, the recipient will recognize ordinary income equal to the fair market value of the stock or cash received upon such exercise. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code, and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock appreciation right.

# Proposal 3
Approval of the
AmpliPhi Biosciences Corporation 2016 Employee Stock Purchase Plan

## Overview

On April 21, 2016, the Board of Directors adopted the AmpliPhi Bioscience Corporation 2016 Employee Stock Purchase Plan, or the ESPP, subject to shareholder approval at the annual meeting. There are 120,000 shares of common stock initially reserved for issuance under the ESPP. In this Proposal 3, we are requesting approval by our shareholders of the ESPP.

The material features of the ESPP are outlined below. This summary is qualified in its entirety by reference to the complete text of the ESPP. Shareholders are encouraged to read the actual text of the ESPP, which is appended to this proxy statement as Appendix B and may be accessed from the SEC’s website at www.sec.gov.

If this Proposal 3 is approved by our shareholders, the ESPP will become effective as of the date of the annual meeting. In the event that our shareholders do not approve this Proposal 3, the ESPP will not become effective.

## Forecasted Utilization Rates and Dilution

We manage our long-term shareholder dilution by limiting the number of equity incentive awards granted annually. The Compensation Committee carefully monitors our annual burn rate, dilution, and equity expense to ensure that we maximize shareholders’ value by granting only the appropriate number of equity incentive awards necessary to attract, reward, and retain employees.

We cannot determine at this time the participants who will be granted options to purchase shares under the ESPP, the amount of any such options or purchases, or the potential value of such options or purchases to participants as the election to participate and the amount of any purchases under the ESPP will be determined by the individual employees in their sole discretion and the purchase price has not yet been determined; however, all participants are subject to the purchase limitations set forth in the ESPP. Under the terms of the proposed ESPP and the anticipated terms of the offerings, the number of shares of our common stock which a participant could purchase during any six month purchase period is limited to 7,000 shares, and the number of shares of our common stock which all participants could purchase during any six month purchase period is limited to 45,000 shares. In addition, the fair market value of shares purchased by an individual participant in the ESPP may not exceed $25,000 in any calendar year.

## Purpose; General

The purpose of the ESPP is to provide a means by which our employees may be given an opportunity to purchase shares of our common stock through payroll deductions, to assist us in retaining the services of our employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for our success. If the ESPP is approved by our shareholders, approximately eight of our employees will initially be eligible to participate in the ESPP.

The rights to purchase common stock granted under the ESPP are intended to qualify as options issued under an “employee stock purchase plan,” as that term is defined in Section 423(b) of the Internal Revenue Code of 1986, as amended, or the Code.

## Administration

The Board of Directors administers the ESPP and has the final power to construe and interpret both the ESPP and the rights granted under it. The Board of Directors has the power, subject to the provisions of the ESPP, to determine when and how rights to purchase common stock will be granted, the provisions of each offering of such rights (which need not be identical), and whether employees of any subsidiary of AmpliPhi will be eligible to participate in the ESPP.

30

The Board of Directors has the power to delegate administration of the ESPP to a committee comprised of one or more members of the Board of Directors. The Board of Directors has delegated administration of the ESPP to the Compensation Committee. As used herein with respect to the ESPP, the “Board of Directors” refers both to the Board of Directors and to any committee the Board of Directors appoints, including the Compensation Committee.

## Stock Subject to ESPP

Subject to approval of this Proposal 3, an aggregate of 120,000 shares of our common stock has been initially reserved for issuance under the ESPP. Additionally, the number of shares of our common stock reserved for issuance under the ESPP will automatically increase on January 1 of each year, beginning on January 1, 2017 and including January 1, 2026, by the lesser of (i) 1% of the total number of shares of our common stock outstanding on December 31 of the preceding calendar year, (ii) 300,000 shares of common stock, or (iii) such lesser number of shares of common stock as determined by the Board of Directors. If purchase rights granted under the ESPP terminate without being exercised, the shares of common stock not purchased under such rights again become available for purchase under the ESPP. The shares of common stock purchasable under the ESPP will be shares of authorized but unissued or reacquired common stock, including shares that may be repurchased by us on the open market. The closing price of our common stock as reported on The NYSE MKT on May 20, 2016 was $1.57 per share.

## Offerings

The ESPP is implemented by offerings of rights to all eligible employees from time to time. The Board of Directors determines the terms and conditions of offerings The maximum length for an offering under the ESPP is twenty-seven (27) months. The provisions of separate offerings need not be identical. When an eligible employee elects to join an offering period, he or she is granted a purchase right to acquire shares of common stock on each purchase date within the offering period. On the purchase date, all payroll deductions collected from the participant during the purchase period are automatically applied to the purchase of common stock, subject to certain limitations (which are described further below under “Eligibility”).

The Board of Directors currently anticipates that each offering under the ESPP will be 24 months long, consisting of four separate six month “purchase periods.” The first day of an offering is referred to as an “offering date,” and the last day of an offering and purchase period is referred to as a “purchase date.” Subsequent 24 month offerings will commence following the expiration of each offering, unless longer or shorter offerings and/or purchase periods are established and approved by the Board of Directors. If any offering date is not a trading day (i.e., a day on which the NYSE MKT, or any other exchange or market on which shares of our common stock are listed, is not open for trading), then the offering date will fall on the next subsequent trading day, and if the last day of an offering and purchase period falls on a day that is not a trading day, then the purchase date for that offering and purchase period will instead fall on the immediately preceding trading day.

## Eligibility

The Board of Directors has the power to exclude certain part-time employees and certain highly compensated employees under applicable tax laws. No employee is eligible to participate in the ESPP if, immediately after the grant of purchase rights, the employee would own, directly or indirectly, stock possessing 5% or more of the total combined voting power or value of all classes of stock or of any parent or subsidiary of AmpliPhi. In addition, no employee may purchase more than $25,000 worth of common stock (determined based on the fair market value of the shares at the time such rights are granted) under all employee stock purchase plans of AmpliPhi and our subsidiary corporations in any calendar year; provided, that any unused limit in one year may be carried over to a future year to the extent permitted by applicable tax laws.

## Participation in the ESPP

Eligible employees will generally enroll in the ESPP by delivering to us, prior to the date selected by the Board of Directors as the offering date for the applicable offering, an agreement authorizing payroll deductions. However, for the initial offering under the ESPP which will commence on the date of the annual meeting, we anticipate that each eligible employee will be automatically enrolled in such offering and will

31

have a two week period after the date of the annual meeting to elect to either authorize payroll deductions or withdraw from such offering. Currently, such payroll deductions are limited to 15% of an employee’s base salary or base wages earned during the offering and other compensation, such as overtime pay, bonuses and commissions, and the spread on the exercise of an option, is excluded from such calculation.

## Purchase Price

The purchase price per share at which shares of common stock are sold in an offering under the ESPP may not be less than the lower of (i) 85% of the fair market value of a share of common stock on the first day of the offering period and (ii) 85% of the fair market value of a share of common stock on the purchase date (i.e., the last day of the applicable purchase period). If the scheduled purchase date is not a trading day, the purchase will occur on the immediately preceding trading day.

## Payment of Purchase Price; Payroll Deductions

The purchase price of the shares is funded by accumulated payroll deductions during the offering. All payroll deductions made on behalf of a participant are credited to his or her account under the ESPP and deposited with our general funds.

## Purchase of Shares

In connection with offerings made under the ESPP, the Board of Directors may specify a maximum number of shares of common stock an employee may be granted the right to purchase and the maximum aggregate number of shares of common stock that may be purchased pursuant to such offering by all participants. The Board of Directors currently anticipates that the terms of offerings will provide maximum number of shares that may be purchased during any six month purchase period by any single eligible employee will be 7,000 shares and the number purchasable during such six month period by all eligible employees will be 45,000 shares.

If the aggregate number of shares to be purchased upon exercise of all outstanding purchase rights would exceed the number of shares of common stock remaining available under the ESPP, or the maximum number of shares that may be purchased on a single purchase date across all offerings, the Board of Directors would make a pro rata allocation (based on each participant’s accumulated payroll deductions) of available shares. Unless the employee’s participation is discontinued, his or her right to purchase shares is exercised automatically at the end of the purchase period at the applicable price. See “Withdrawal” below.

## Withdrawal

Although each participant in the ESPP is required to sign an agreement authorizing payroll deductions, the participant may withdraw from a given offering by terminating his or her payroll deductions and by delivering to us a notice of withdrawal from the ESPP. Such withdrawal may be elected at any time prior to the end of the applicable offering, except as otherwise provided in the offering document.

Upon any withdrawal from an offering by an employee, we will distribute to the employee his or her accumulated payroll deductions without interest (unless otherwise required by applicable local law) and such employee’s rights in the offering will be automatically terminated. The employee is not entitled to again participate in that offering. However, an employee’s withdrawal from an offering will not prevent such employee from participating in subsequent offerings under the ESPP.

## Reset Feature

The Board of Directors has the authority to provide that if the fair market value of a share of our common stock on the first day of any purchase period within a particular offering period is less than or equal to the fair market value on the start date of that offering period, then the participants in that offering period will automatically be transferred and enrolled in a new offering period which will begin on the first day of that purchase period and the participants’ purchase rights in the original offering period will terminate. The Board of Directors currently anticipates that the terms of offering periods will include such a reset feature.

32

## Termination of Employment

Unless otherwise specified by the Board of Directors, a participant’s rights under any offering under the ESPP terminate immediately upon cessation of an employee’s employment for any reason (subject to any post-employment participation period required by law), and we will distribute to such employee all of his or her accumulated payroll deductions, without interest (unless otherwise required by applicable law).

## Capitalization Adjustment Provisions

Upon certain transactions by AmpliPhi, such as a merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other similar transaction, the ESPP share reserve, the number and class of shares by which the ESPP share reserve may increase each year pursuant to the “evergreen” provision, the outstanding purchase rights thereunder, and any purchase limits will be appropriately adjusted as to the type, class, maximum number of shares and purchase price subject thereto.

## Effect of Certain Corporate Transactions

In the event of a corporate transaction (as defined in the ESPP and described below), then any surviving or acquiring corporation may assume or continue outstanding purchase rights under the ESPP or may substitute similar rights for outstanding purchase rights. If any surviving or acquiring corporation does not assume or continue such rights or substitute similar rights, then the participants’ accumulated payroll deductions will be used to purchase shares of common stock within ten business days prior to the corporate transaction under the ongoing offering and the participants’ rights under the ongoing offering will terminate immediately after such purchase.

A “corporate transaction” generally means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events:

| • | the consummation of a sale or other disposition of all or substantially all, as determined by the Board of Directors in its sole discretion, of the consolidated assets of the Company and its subsidiaries;

| • | the consummation of a sale or other disposition of at least 50% of our outstanding securities; or

| • | the consummation of certain specified types of mergers, consolidations or similar transactions.

## Duration, Amendment and Termination

The Board of Directors may amend, suspend or terminate the ESPP at any time. However, except in regard to capitalization adjustments (as described above), to the extent shareholder approval is required by applicable law or listing requirements, then any amendment to the ESPP must be approved by our shareholders if the amendment would:

| • | materially increase the number of shares of common stock available for issuance under the ESPP;

| • | materially expand the class of individuals eligible to participate under the ESPP;

| • | materially increase the benefits accruing to participants under the ESPP or materially reduce the price at which shares of common stock may be purchased under the ESPP;

| • | materially extend the term of the ESPP; or

| • | expand the types of awards available for issuance under the ESPP.

The Board of Directors may amend outstanding purchase rights without a participant’s consent if such amendment is necessary to ensure that the purchase right complies with the requirements of Section 423 of the Code.

Rights granted before amendment or termination of the ESPP will not be impaired by any amendment or termination of the ESPP without the consent of the participant to whom such rights were granted, except as necessary to comply with applicable laws, or as necessary to obtain or maintain favorable tax, listing or regulatory treatment.

33

## U.S. Federal Income Tax Information

The following is a summary of the principal United States federal income taxation consequences to participants and us with respect to participation in the ESPP. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, and other tax consequences of the grant or exercise of an option or the disposition of common stock acquired under the ESPP. The ESPP is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Purchase rights granted under the ESPP are intended to qualify for favorable federal income tax treatment associated with rights granted under an employee stock purchase plan that qualifies under provisions of Section 423 of the Code.

A participant will be taxed on amounts withheld for the purchase of shares of common stock as if such amounts were actually received. Otherwise, no income will be taxable to a participant as a result of the granting or exercise of a purchase right until disposition of the acquired shares. The taxation upon disposition will depend upon the holding period of the acquired shares.

If the stock is disposed of more than two years after the beginning of the offering period and more than one year after the stock is transferred to the participant, then the lesser of:

| (1) | the excess of the fair market value of the stock at the time of such disposition over the purchase price, or

| (2) | the excess of the fair market value of the stock as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period) will be treated as ordinary income.

Any further gain or any loss will be taxed as a long-term capital gain or loss. At present, such capital gains generally are subject to lower tax rates than ordinary income.

If the stock is sold or disposed of before the expiration of either of the holding periods described above, then the excess of the fair market value of the stock on the purchase date over the purchase price will be treated as ordinary income at the time of such disposition. The balance of any gain will be treated as capital gain. Even if the stock is later disposed of for less than its fair market value on the purchase date, the same amount of ordinary income is attributed to the participant, and a capital loss is recognized equal to the difference between the sales price and the fair market value of the stock on such purchase date. Any capital gain or loss will be short-term or long-term, depending on how long the stock has been held.

There are no federal income tax consequences to us by reason of the grant or exercise of rights under the ESPP. We are entitled to a deduction to the extent amounts are taxed as ordinary income to a participant (subject to the requirement of reasonableness and the satisfaction of tax reporting obligations).

## New Plan Benefits

Participation in the ESPP is voluntary and each eligible employee will make his or her own decision regarding whether and to what extent to participate in the ESPP. It is, therefore, not possible to determine the benefits or amounts that will be received in the future by individual employees or groups of employees under the ESPP.

## Vote Required; Recommendation of the Board of Directors

In order for Proposal 3 to be approved, the number of shares that vote “For” the proposal must exceed the number of shares that vote “Against” the proposal. Abstentions will be counted towards the vote total for Proposal 3 and will have the same effect as “Against” votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

# The Board of Directors Recommends
a Vote “For” Proposal 3.

# Proposal 4
Approval of the reincorporation of the Company in the State of Delaware, to be effected through a
merger with and into a newly formed and wholly owned Delaware subsidiary

## What is the Reincorporation Proposal?

On April 21, 2016, the Board of Directors, which we refer to, for purposes of this Proposal 4, as the “Board” or the “AmpliPhi Board,” of AmpliPhi Biosciences Corporation, which we refer to, for the purposes of this Proposal 4, as the “Company,” “AmpliPhi” or “AmpliPhi Washington,” approved a proposal, or the Reincorporation Proposal, to change the state of incorporation of AmpliPhi from Washington to Delaware, or the Reincorporation. The Board believes that the Reincorporation can improve corporate governance, reduce administrative costs, and enhance long-term shareholder value.

The choice of state of domicile is important because state corporate law governs the internal affairs of a corporation. Management and boards of directors of corporations look to state law and judicial interpretations of state law to guide their decision-making on many key issues, including determining appropriate governance policies and procedures, ensuring that boards satisfy their fiduciary obligations to shareholders, and evaluating key strategic alternatives for the corporation, including mergers, acquisitions, and divestitures. After careful consideration of these and other factors as discussed more fully below, the AmpliPhi Board believed that it is in the best interest of AmpliPhi and its shareholders to complete the Reincorporation.

## Where can I find information on the Reincorporation Proposal?

Shareholders are urged to read this proxy statement carefully for information regarding the Reincorporation Proposal, including the related appendices referenced below and attached to this proxy statement, before voting on the Reincorporation. The following discussion summarizes material provisions of the Reincorporation. This summary is subject to and qualified in its entirety by the following reincorporation documents attached as appendices to this proxy statement: the Agreement and Plan of Merger to be executed in connection with the Reincorporation in substantially the form attached hereto as Appendix C, the Delaware Certificate of Incorporation to be effective after the Reincorporation, in the form attached hereto as Appendix D (the “Delaware Charter”) and the Delaware Bylaws to be effective after the Reincorporation, in the form attached hereto as Appendix E (the “Delaware Bylaws”). Copies of our Amended and Restated Washington Articles of Incorporation, as amended (“Washington Charter”) and our Washington Amended and Restated Bylaws (the “Washington Bylaws”) are filed publicly as exhibits to our periodic reports and are also available for inspection at our principal office. Copies will be sent to shareholders free of charge upon written request to our Secretary at AmpliPhi Biosciences Corporation at 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

## Why did our Board of Directors choose Delaware over other jurisdictions?

It is well established that the State of Delaware has been a leader in adopting a comprehensive and coherent set of corporate laws that are responsive to the evolving legal and business needs of corporations. Our Board of Directors believes that the most important criterion in comparing jurisdictions is the existence of a highly developed and predictable corporate law that will guide management and our Board of Directors in addressing the complex and varied decisions faced by public companies. We believe that no other jurisdiction in the United States satisfies this criterion to the same extent as Delaware. In particular, relative to our current domicile in Washington or a domicile in any other state, we believe Delaware will offer us greater predictability and clarity due to characteristics that are unique to the state, which are further discussed below.

#### Predictability, Flexibility and Responsiveness of Delaware Law

Delaware courts have established a jurisprudence that is significantly more thorough and broadly applied with respect to principles of corporate governance than any other state’s courts, including the courts in Washington. As a result, corporations domiciled in Delaware have an advantage over companies organized under the laws of other states, because Delaware corporations can draw upon these firmly established and consistently interpreted principles when making business and legal decisions.

We believe that Delaware is the preferred domicile for most major American corporations. According to the Delaware Secretary of State, over 50 percent of all public companies and approximately 64 percent of all Fortune 500 corporations are incorporated in Delaware.

35

Because of the large number of major corporations domiciled in Delaware, Delaware courts often take the lead in reviewing and deciding important new issues relating to corporate governance and rights and obligations of shareholders and corporations. As Delaware courts were among the first and most influential to address these issues, many corporations in Washington and other states have looked to Delaware laws for guidance on these issues. The Board believes that the clarity provided on these issues is ultimately beneficial to AmpliPhi and our shareholders because it establishes more reliable guidance for corporate governance decisions.

Delaware’s court system also provides swift and efficient resolutions in corporate litigation. Delaware has a specialized Court of Chancery that reviews and decides corporate law cases, and appeals to Delaware’s Supreme Court can be decided quickly. In addition, Delaware passed the Delaware Rapid Arbitration Act, which became effective on May 4, 2015, and which provides a streamlined arbitration process that will allow for prompt, cost-effective resolution of business disputes.

We have identified the following key benefits of Delaware’s corporate legal framework that are available to AmpliPhi after the Reincorporation:

| • | The Delaware General Corporate Law, as amended (the “DGCL”), is generally acknowledged to be the most advanced and flexible state corporate statute in the United States;

| • | The Delaware Court of Chancery routinely handles cases involving complex corporate issues with a level of experience and a degree of sophistication and understanding unmatched by other courts in the country;

| • | The Delaware Supreme Court is well regarded and is timely and highly responsive in cases involving complex corporate issues;

| • | The well-established body of case law construing Delaware law has developed over the last century and provides businesses with a greater predictability on numerous issues than the case law of most, if not all, other jurisdictions, including, but not limited to, Washington;

| • | The Delaware legislature each year considers and adopts statutory amendments in an effort to ensure that the Delaware corporate statute continues to be responsive to the changing needs of businesses;

| • | Delaware has a user-friendly Office of Secretary of State that facilitates filings and interactions and reduces (as compared to other states) complications and delays that can arise in time sensitive transactions.

### Ability to Have the Delaware Courts Serve as the Exclusive Forum for the Adjudication of Certain Legal Matters

To ensure that we get the full benefits of Delaware’s corporate legal framework, the Board has decided to include in the Delaware Charter a provision providing that the Delaware Courts are the exclusive forum for the adjudication of certain legal actions.

Under the exclusive forum provision contained in the Delaware Charter, the state courts of the State of Delaware (or if no state court has jurisdiction, the federal district court for the District of Delaware) will be the exclusive forum for certain actions involving AmpliPhi, unless AmpliPhi consents to an alternative forum. Based on the proposed language in the Delaware Charter, the Delaware courts would be the exclusive forum for (i) derivative actions or proceedings brought on behalf of AmpliPhi; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to AmpliPhi or its stockholders; (3) any action asserting a claim against AmpliPhi or any director or officer or other employee arising pursuant to any provision of the DGCL, the Delaware Charter or the Delaware Bylaws; and (4) any action asserting a claim against AmpliPhi or any director or officer or other employee governed by the internal affairs doctrine.

The exclusive forum provision contained in the Delaware Charter is intended to assist AmpliPhi in avoiding multiple lawsuits in multiple jurisdictions on matters relating to the corporate law of Delaware, which will be our state of incorporation if the Reincorporation Proposal is approved. AmpliPhi believes that the exclusive forum provision in the Delaware Charter will reduce the risk that AmpliPhi could become subject to duplicative litigation in multiple forums, as well as the risk that the outcome of cases in multiple forums

36

could be inconsistent, even though each forum purports to follow Delaware law. Any of these could expose AmpliPhi to increased expenses or losses.

The exclusive forum provision contained in the Delaware Charter would only regulate the forum where our shareholders may file claims relating to the specified intra-corporate disputes. The exclusive forum provision does not contain any restrictions on the ability of our shareholders to bring such claims, nor the remedies available if such claims are ultimately successful; rather it attempts to prevent AmpliPhi from being forced to waste corporate assets defending against duplicative suits.

Although the Board of Directors believes that the designation of the Delaware Court of Chancery as the exclusive forum for intra-corporate disputes serves the best interests of AmpliPhi and our shareholders as a whole, the Board of Directors also believes that we should retain the ability to consent to an alternative forum on a case-by-case basis. Specifically, where the Board of Directors determines that AmpliPhi’s interests and those of our shareholders are best served by permitting a dispute to proceed in a forum other than the Delaware Court of Chancery, the exclusive forum provision in the Delaware Charter permits AmpliPhi to consent to the selection of such alternative forum.

The Board of Directors believes that our shareholders will benefit from having intra-corporate disputes litigated in the Delaware Court of Chancery. Although some plaintiffs might prefer to litigate such matters in a forum outside of Delaware because they perceive another court as more convenient or more favorable to their claims (among other reasons), the Board of Directors believes that the substantial benefits to us and our shareholders as a whole from designating the Delaware Court of Chancery as the exclusive forum for intra-corporate disputes outweigh these concerns. The Delaware Court of Chancery is widely regarded as the preeminent court for the determination of disputes involving a corporation’s internal affairs in terms of precedent, experience and focus. The Court’s considerable expertise has led to the development of a substantial and influential body of case law interpreting Delaware’s corporate law. This provides us and our shareholders with more predictability regarding the outcome of intra-corporate disputes. In addition, the Delaware Court of Chancery has developed streamlined procedures and processes that help provide decisions for litigating parties on a relatively expedited basis. This accelerated schedule can limit the time, cost, and uncertainty of litigation for all parties. Furthermore, there is a significant risk that allowing shareholders to bring such highly sophisticated matters in forums with little familiarity or experience in corporate governance leaves shareholders at risk that foreign jurisdictions may misapply Delaware law.

Without the exclusive forum provision in the Delaware Charter, AmpliPhi remains exposed to the possibility of plaintiffs using AmpliPhi’s more diverse operational base to bring claims against AmpliPhi in multiple jurisdictions or choosing a forum state for litigation that may not apply Delaware law to AmpliPhi’s internal affairs in the same manner as the Delaware courts would be expected to do so.

## What are the consequences of the Reincorporation?

At the effective time of the Reincorporation, we will be governed by the Delaware Charter, the Delaware Bylaws and the DGCL. Although the Delaware Charter and the Delaware Bylaws contain many similar provisions from our existing Amended and Restated Articles of Incorporation, as amended, or the Washington Articles, and Amended and Restated Bylaws, or the Washington Bylaws, there are important differences that are discussed below. See “What are the differences between the charters and bylaws of AmpliPhi Washington and AmpliPhi Delaware? What are the material differences between Delaware law and Washington law?” below.

After the Reincorporation, our name will remain AmpliPhi Biosciences Corporation. Other than the change in corporate domicile (and certain related changes of a legal nature in our organizational documents, which are described in this proxy statement), the Reincorporation will not result in any change in our name, business operations, management, board composition, fiscal year, assets, liabilities or net worth, or physical location, nor will it result in any change in location of our current employees, including management. Upon consummation of the Reincorporation, our daily business operations will continue as they are presently conducted. In addition, the Reincorporation will not, we believe, significantly affect any of our material contracts with any third parties and our rights and obligations under these contractual arrangements will continue and be assumed by AmpliPhi Delaware. In addition, upon the effectiveness of the Merger, the directors who are elected at the annual meeting as directors of AmpliPhi will become directors of AmpliPhi

37

Delaware, and the individuals serving as executive officers of AmpliPhi immediately prior to the Reincorporation will continue to serve as executive officers of AmpliPhi Delaware, without a change in title or responsibilities.

Upon consummation of the Reincorporation, our daily business operations will continue as they are presently conducted at our current principal executive office located at 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

## What are the differences between the charters and bylaws of AmpliPhi Washington and AmpliPhi Delaware? What are the material differences between Delaware law and Washington law?

Because of differences between the Revised Code of Washington (the “RCW”) and the DGCL, as well as differences between the Company’s charter and bylaws before and after the Reincorporation, the Reincorporation will effect some changes to the rights of the Company’s shareholders. Summarized below are the most significant differences between the rights of the shareholders of the Company before and after the Reincorporation, as a result of the differences among the RCW and the DGCL, the Washington Charter and the Delaware Charter, and the Washington Bylaws and the Delaware Bylaws.

The summary below is not intended to be relied upon as an exhaustive list of all differences or a complete description of the differences between the DGCL and the Delaware Charter and Bylaws, on the one hand, and the RCW and the Washington Charter and Bylaws on the other hand. The summary below is qualified in its entirety by reference to the RCW, the Washington Charter, the Washington Bylaws, the DGCL, the Delaware Charter and the Delaware Bylaws.

##### Authorized Capital Stock

#### Delaware Provisions

AmpliPhi Delaware’s authorized capital stock will consist of 150,000,000 authorized shares of common stock, $0.01 par value, and 10,000,000 authorized shares of preferred stock, $0.01 par value. All of the shares of AmpliPhi Delaware common stock issued in connection with the Reincorporation will be validly issued, fully paid and non-assessable.

The holders of AmpliPhi Delaware common stock will be entitled to one vote for each share on all matters voted on by shareholders, including the election of directors. The holders of AmpliPhi Delaware common stock will not have any cumulative voting, conversion, redemption or preemptive rights. The holders of AmpliPhi Delaware common stock will be entitled to such dividends as may be declared from time to time by the AmpliPhi Delaware Board of Directors from funds available therefor, and upon liquidation will be entitled to receive pro rata all assets of AmpliPhi Delaware available for distribution to such holders.

#### Washington Provisions

The holders of the Company’s common stock are entitled to one vote for each share on all matters voted on by shareholders, including the election of directors. The Company’s authorized capital stock consists of (i) 670,000,000 authorized shares of common stock, par value $0.01 per share, and (ii) 10,000,000 authorized shares of preferred stock, par value $0.01 per share. The holders of the Company’s common stock do not have any cumulative voting, conversion, redemption or preemptive rights.

##### Number of Directors; Election; Removal; Filling Vacancies; Independent Directors

#### Delaware Provisions

The Delaware Charter and Delaware Bylaws will provide that the number of directors will be fixed from time to time by action of the Board of Directors. Delaware law permits corporations to classify their board of directors so that less than all of the directors are elected each year to overlapping terms. The Delaware Charter will provide for directors to be divided into three classes designated as Class I, Class II and Class III, respectively. The classes correspond to the current classification of the Board. Accordingly, if this proposal is approved at the annual meeting, the term of office of the Class I directors will expire at our 2019 Annual Meeting of Shareholders, the term of office of the Class II directors will expire at our 2017 Annual Meeting of Shareholders and the term of office of the Class III directors will expire at our 2018 annual meeting of shareholders. The term of each class will be three years, beginning on the date of the annual meeting at which

38

such directors are elected and ending on the date of the third annual meeting thereafter. At the second annual meeting of stockholders following such initial classification, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the third annual meeting of stockholders following such initial classification, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting.

The Delaware Charter and Bylaws provide that the stockholders may remove one or more directors with cause at a special meeting called for the purpose of removing the director, or at an annual meeting, upon the affirmative vote of the holders of at least 66 2/3% of the voting power of all then outstanding shares of capital stock of the corporation entitled to vote generally at an election of the directors. A vacancy on the Board of Directors, whether created as a result of the removal of a director or resulting from an enlargement of the Board of Directors, may only be filled by the affirmative vote of a majority of the directors then in office.

#### Washington Provisions

The Washington Bylaws provide that the number of directors shall not be less than one nor more than nine. Under the Washington Charter and Bylaws, the specific number of directors must be set by a resolution of the Board of Directors or the shareholders. The Board is divided into three classes. At each annual meeting of shareholders, the number of directors equal to the number of directors in the class whose term expires at the time of such meeting shall be elected to serve until the third ensuing annual meeting of shareholders. Directors shall serve until their successors are elected and qualified or until their earlier death, resignation or removal from office or until there is a decrease in the number of directors.

The Washington Charter and Bylaws provide that the shareholders may remove one or more directors for cause at a special meeting called for the purpose of removing the director upon the affirmative vote of the holders of at least two-thirds of the shares entitled to elect the director or directors whose removal is sought. A vacancy on the Board of Directors created by the removal of a director shall be filled only by a vote of the holders of at least two-thirds of the shares then entitled to elect the director removed. Any other vacancy may be filled by the shareholders or by the affirmative vote of a majority of the remaining directors.

Under the RCW, shareholders may remove one or more directors with or without cause unless the articles of incorporation provide that directors may be removed only for cause. A director may be removed by the shareholders only at a special meeting called for that purpose. If a vacancy occurs on the Board of Directors either the shareholders or the directors shall fill the vacancy.

##### Cumulative Voting for Directors

#### Delaware Provisions

Delaware law permits cumulative voting if provided in the certificate of incorporation. The Delaware Charter does not provide for cumulative voting.

#### Washington Provisions

Under Washington law, unless the articles of incorporation provide otherwise, shareholders are entitled to use cumulative voting in the election of directors. The Washington Charter expressly prohibits cumulative voting.

##### Business Combinations; Interested Transactions

#### Delaware Provisions

Section 203 of the DGCL provides that, subject to certain exceptions specified therein, a corporation shall not engage in any business combination with any “interested stockholder” for a three-year period following the date that such stockholder becomes an interested stockholder unless (i) prior to such date, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder, (ii) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding shares held by directors who are also officers and employee stock purchase plans in which employee participants do not have

39

the right to determine confidentially whether plan shares will be tendered in a tender or exchange offer), or (iii) on or subsequent to such date, the business combination is approved by the board of directors of the corporation and by the affirmative vote at an annual or special meeting, and not by written consent, of at least 66- 2/3% of the outstanding voting stock which is not owned by the interested stockholder. Except as specified in Section 203 of the DGCL, an interested stockholder is defined to include (a) any person that is the owner of 15% or more of the outstanding voting stock of the corporation or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation, at any time within three years immediately prior to the relevant date, and (b) the affiliates and associates of any such person.

Under certain circumstances, Section 203 of the DGCL may make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period, although the corporation’s certificate of incorporation or stockholders may elect to exclude a corporation from the restrictions imposed thereunder. The Delaware Charter does not exclude AmpliPhi Delaware from the restrictions imposed under Section 203 of the DGCL. It is anticipated that the provisions of Section 203 of the DGCL may encourage companies interested in acquiring AmpliPhi Delaware to negotiate in advance with AmpliPhi Delaware’s Board of Directors, since the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction which results in the stockholder becoming an interested stockholder.

#### Washington Provisions

Section 23B.19.040 of the RCW provides that a Washington public company may not, for a period of five years following the date on which a shareholder becomes the beneficial owner of ten percent or more of the corporation’s outstanding shares, without the prior approval of the corporation’s board of directors of the transaction or of the acquisition by the shareholder resulting in the shareholder’s ownership of ten percent or more of the corporation’s outstanding shares, engage in (i) a merger, share exchange, or consolidation with such shareholder or an affiliate of such shareholder, (ii) a sale or other disposition to such shareholder of assets with a value equal to five percent or more of the aggregate market value of all the corporation’s assets, or having an aggregate value equal to five percent or more of the aggregate market value of all the outstanding shares of the corporation, or representing five percent or more of the earning power of the corporation, (iii) a termination, as a result of such shareholder’s acquisition of ten percent or more of the shares of the corporation, of five percent or more of the employees of the corporation employed in Washington whether at one time or over the five-year period following the date that the shareholder acquires ten percent of the corporation’s voting securities, (iv) an issuance, transfer or redemption by the corporation of shares, options or warrants to such shareholder, (v) a liquidation or dissolution proposed by or pursuant to an agreement with such shareholder, (vi) a reclassification of securities, including any share splits, share dividend or other distribution of shares in respect of stock, proposed by or pursuant to any agreement with such shareholder that has the effect of increasing the proportionate share of the outstanding shares of a class of shares owned by such shareholder, or (vii) a transaction with such shareholder in which the corporation makes any loans or advances to such shareholder or provides other financial assistance or tax credits or other tax advantages to such shareholder through the target corporation.

The Company is not aware of any specific effort by any party to assume control of the Company. Because the RCW includes provisions affecting acquisitions and business combinations, the possibility that Section 203 of the DGCL may impede the accomplishment of mergers with, or the assumption of control of, the Company is not among the principal reasons for the Reincorporation.

##### Limitation of Liability of Directors

#### Delaware Provisions

The DGCL permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of a director to the corporation or its stockholders for damages for certain breaches of the director’s fiduciary duty. However, no such provision may eliminate or limit the liability of a director: (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) for declaration of unlawful dividends or illegal redemptions or stock repurchases; or (iv) for any transaction from which the director derived an improper personal benefit.

40

The Delaware Charter provides that the liability of the directors for monetary damages shall be eliminated to the fullest extent allowed under applicable law. While these provisions provide directors with protection from awards for monetary damages for breaches of their duty of care, they do not eliminate such duty. Accordingly, these provisions will have no effect on the availability of equitable remedies such as an injunction or rescission based on a director’s breach of his or her duty of care.

#### Washington Provisions

The RCW permits a corporation to include in its articles of incorporation provisions that eliminate or limit the personal liability of a director to the corporation or its shareholders for monetary damages for conduct as a director, provided that such provisions may not eliminate or limit the liability of a director for acts or omissions that involve (i) intentional misconduct by the director or a knowing violation of law by a director, (ii) liability for unlawful distributions, or (iii) for any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.

The Washington Charter provides that a director of the Company will not be liable to the corporation or its shareholders for monetary damages for any conduct as a director to the fullest extent permitted by the RCW.

##### Indemnification of Officers and Directors

Both the RCW and the DGCL permit a corporation to indemnify officers, directors, employees and agents for actions taken in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action, which they had no reasonable cause to believe was unlawful. Both states’ laws provide that a corporation may advance expenses of defense (upon receipt of a written undertaking to reimburse the corporation if indemnification is not appropriate), and both states permit a corporation to purchase and maintain liability insurance for its directors and officers.

#### Delaware Provisions

The DGCL provides that indemnification may not be made for any matter as to which a person has been adjudged by a court of competent jurisdiction to be liable to the corporation, unless and only to the extent a court determines that the person is entitled to indemnity for such expenses as the court deems proper.

The Delaware Bylaws provide that AmpliPhi Delaware shall indemnify directors, officers and agents to the fullest extent permitted by the DGCL or other applicable law and that AmpliPhi Delaware may purchase and maintain insurance on behalf of any person who is or was serving as a director, officer, employee or agent of the Company. The Delaware Charter provides that AmpliPhi Delaware is authorized to indemnify its directors, officers and agents to the maximum extent permitted by applicable law through bylaw provisions or agreements with such persons.

#### Washington Provisions

The RCW provides that a corporation may not indemnify a director in connection with a proceeding in which the director was adjudged liable to the corporation or in connection with any other proceeding charging improper personal benefit to the director in which the director was adjudged liable on the basis that personal benefit was improperly received by the director.

The Washington Bylaws provide that each person who was, is or is threatened to be made a named party to or is otherwise involved (including, without limitation, as a witness) in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative and whether formal or informal, by reason of the fact that he or she is or was a director or officer of the corporation or, that being or having been such a director or officer or an employee of the corporation, he or she is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another corporation or of a partnership, joint venture, trust, employee benefit plan or other enterprise, whether the basis of a proceeding is alleged action in an official capacity as such a director, officer, partner, trustee, employee or agent or in any other capacity while serving as such a director, officer, partner, trustee, employee or agent, shall be indemnified and held harmless by the corporation against all expense, liability and loss actually and reasonably incurred or suffered by such indemnitee in connection therewith, and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, partner, trustee, employee or agent and shall inure to the benefit of the indemnitee's heirs, executors and administrators.

41

##### Special Meetings of Shareholders

#### Delaware Provisions

Under the DGCL, a special meeting of stockholders may be called by the corporation’s board of directors or by such persons as may be authorized by the corporation’s certificate of incorporation or bylaws. The Delaware Bylaws provide that a special meeting may be called at any time by (i) the Chairman of the Board, (ii) the Chief Executive Officer, or (iii) the Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors.

#### Washington Provisions

Under the RCW, a corporation must hold a special meeting of shareholders upon request by the board of directors or by such persons authorized to do so by the articles of incorporation or bylaws. A corporation must also hold a special meeting of shareholders if the holders of at least ten percent of all votes entitled to be cast at a special meeting deliver to the corporation a demand for a special meeting. However, a corporation that is a public company may in its articles of incorporation limit or deny the right of shareholders to call a special meeting. A corporation other than a public company may require that shareholders who hold a greater amount than ten percent of the outstanding shares may call a special meeting of shareholders provided that the amount is not greater than twenty-five percent.

The Washington Charter and Bylaws provide that special meetings of shareholders may be called by (i) the Board, (ii) the Chairman of the Board, (iii) the President of the Company or (iv) upon written demand by the holders of at least 30% of all the votes entitled to be cast on any issue proposed to be considered at such meeting.

##### Amendment or Repeal of the Certificate of Incorporation

#### Delaware Provisions

Under the DGCL, unless the certificate of incorporation otherwise provides, amendments to the certificate of incorporation generally require the approval of the holders of a majority of the outstanding stock entitled to vote thereon, and if the amendment would increase or decrease the number of authorized shares of any class or series or the par value of such shares, or would adversely affect the rights, powers or preferences of such class or series, a majority of the outstanding stock of such class or series also would have to approve the amendment. The Delaware Charter provides that the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote generally in the election of directors, voting as a single class, is required to amend certain provisions of the Delaware Charter, including those related to the Board, indemnification of directors and officers, forum selection, and amendment of the Delaware Charter.

#### Washington Provisions

Under the RCW, the board of directors may amend the Company’s articles of incorporation without shareholder approval (i) to change any provisions with respect to the par value of any class of shares, (ii) to delete the names and addresses of the initial directors, (iii) to delete the name and address of the initial registered agent or registered officer, (iv) if the corporation has only one class of shares outstanding, solely to effect a forward or reverse stock split, or (v) to change the corporate name. Other amendments to the articles of incorporation must be approved, in the case of a public company, by a majority of the votes entitled to be cast on the proposed amendment. The Washington Charter provides that the Company reserves the right to amend or repeal any provision by the affirmative vote of the holders of a majority of the outstanding shares, except that certain provisions relating to the bylaws, the board of directors, amendments of the charter, special meetings of shareholders and special voting requirements may only be amended by the affirmative vote of the holders of two-thirds of the outstanding shares.

Amendment to Bylaws

#### Delaware Provisions

Under the DGCL, directors may amend the bylaws of a corporation only if such right is expressly conferred upon the directors in its certificate of incorporation. The Delaware Bylaws provide that the Delaware Bylaws may be amended by the Board of Directors or upon the affirmative vote of the holders of at least 66 2/3% of

42

the voting power of all of the then-outstanding shares of the capital stock of the corporation entitled to vote generally in the election of directors, voting together as a single class.

#### Washington Provisions

The RCW provides that the board of directors may amend or repeal the corporation’s bylaws unless the articles of incorporation reserve this power exclusively to the shareholders or the shareholders, in amending or repealing a particular bylaw, provide expressly that the board of directors may not amend or repeal that bylaw. The shareholders may also amend or repeal the corporation’s bylaws, or adopt new bylaws, even though the bylaws may also be amended or repealed by the board of directors. The Washington Charter and Bylaws provide that the Board of Directors has the power to adopt, amend or repeal the bylaws of the Company subject to approval by a majority of the Continuing Directors (defined as any member of the Board of Directors who was a member of the Board of Directors on January 1, 1994 or who is elected to the Board of Directors after January 1, 1994 upon the recommendation of a majority of the Continuing Directors voting separately and as a subclass of Directors on such recommendation), other than any bylaw that the shareholders have expressly provided may not be amended or repealed by the Board. The Washington Bylaws may also be amended by the affirmative vote of the holders of at least two-thirds of the outstanding shares.

##### Merger with Subsidiary

#### Delaware Provisions

The DGCL provides that a parent corporation may merge into a subsidiary and a subsidiary may merge into its parent, without stockholder approval, where such parent corporation owns at least 90% of the outstanding shares of each class of capital stock of its subsidiary.

#### Washington Provisions

The RCW provides that a parent corporation may merge a subsidiary into itself without shareholder approval if the parent corporation owns at least 90% of the outstanding shares of each class of capital stock of its subsidiary.

##### Committees of the Board of Directors

#### Delaware Provisions

The DGCL provides that the board of directors may delegate certain of its duties to one or more committees elected by a majority of the board of directors. A Delaware corporation can delegate to a committee of the board of directors, among other things, the responsibility of nominating candidates for election to the office of director, to fill vacancies on the board of directors, to reduce earned or capital surplus, and to authorize the acquisition of the corporation’s own stock. Moreover, if the corporation’s certificate of incorporation or bylaws, or the resolution of the board of directors creating the committee so permits, a committee of the board of directors may declare dividends and authorize the issuance of stock.

#### Washington Provisions

The RCW also provides that the board of directors may delegate certain of its duties to one or more committees elected by a majority of the board of directors. Under the RCW, each committee may exercise such powers of the board of directors specified by the board of directors; however, a committee may not (i) authorize or approve a distribution except in accordance with a general formula or method prescribed by the board of directors, (ii) approve or propose to shareholders any action that the RCW requires be approved by shareholders, (iii) fill vacancies on the board of directors or on any of its committees, (iv) amend the articles of incorporation, (v) adopt, amend or repeal bylaws, (vi) approve a plan of merger not requiring shareholder approval, or (vii) approve the issuance or sale of shares or determine the designation and relative rights, preferences and limitations of a class or series of shares.

##### Mergers, Acquisitions and Transactions with Controlling Shareholder

#### Delaware Provisions

Under the DGCL, a merger, consolidation, sale of all or substantially all of a corporation’s assets other than in the regular course of business or dissolution of a corporation must be approved by a majority of the outstanding shares entitled to vote. No vote of stockholders of a constituent corporation surviving a merger,

43

however, is required (unless the corporation provides otherwise in its certificate of incorporation) if (i) the merger agreement does not amend the certificate of incorporation of the surviving corporation; (ii) each share of stock of the surviving corporation outstanding before the merger is an identical outstanding or treasury share after the merger; and (iii) the number of shares to be issued by the surviving corporation in the merger does not exceed twenty percent (20%) of the shares outstanding immediately prior to the merger. The Delaware Charter does not make any provision with respect to such mergers.

#### Washington Provisions

Under the RCW, a merger, share exchange, consolidation, sale of substantially all of a corporation’s assets other than in the regular course of business, or dissolution of a public corporation must be approved by the affirmative vote of a majority of directors when a quorum is present, and by two-thirds of all votes entitled to be cast by each voting group entitled to vote as a separate group, unless a higher or lower proportion is specified in the articles of incorporation.

The Washington Charter provides that if a merger is approved by a majority of the Continuing Directors (as defined in the Washington Charter), and is otherwise required to be approved by the Company’s shareholders, such merger shall require the affirmative vote of not less than fifty-one percent (51%) of the outstanding shares entitled to vote thereon.

The RCW also provides that certain mergers need not be approved by the shareholders of the surviving corporation if (i) the articles of incorporation will not change in the merger, except for specified permitted amendments; (ii) no change occurs in the number, designations, preferences, limitations and relative rights of shares held by those shareholders who were shareholders prior to the merger; (iii) the number of voting shares outstanding immediately after the merger, plus the voting shares issuable as a result of the merger, will not exceed the authorized voting shares specified in the surviving corporation’s articles of incorporation immediately prior to the merger; and (iv) the number of participating shares outstanding immediately after the merger, plus the number of participating shares issuable as a result of the merger, will not exceed the authorized participating shares specified in the corporation’s articles of incorporation immediately prior to the merger.

##### Class Voting

#### Delaware Provisions

The DGCL requires voting by separate classes only with respect to amendments to the certificate of incorporation that adversely affect the holders of those classes or that increase or decrease the aggregate number of authorized shares or the par value of the shares of any of those classes.

#### Washington Provisions

Under the RCW, a corporation’s articles of incorporation may authorize one or more classes of shares that have special, conditional or limited voting rights, including the right to vote on certain matters as a group. Under the RCW, a corporation’s articles of incorporation may not limit the rights of holders of a class to vote as a group with respect to certain amendments to the articles of incorporation and certain mergers that adversely affect the rights of holders of that class.

##### Preemptive Rights

#### Delaware Provisions

Under Delaware law, a stockholder does not have preemptive rights unless such rights are specifically granted in the certificate of incorporation. The Delaware Charter does not specifically grant any preemptive rights.

#### Washington Provisions

Under Washington law, a shareholder has preemptive rights unless such rights are specifically denied in the articles of incorporation. The Washington Charter states that shareholders do not have any preemptive rights.

##### Transactions with Officers and Directors

#### Delaware Provisions

The DGCL provides that contracts or transactions between a corporation and one or more of its officers or directors or an entity in which they have an interest are not void or voidable solely because of such interest or

44

the participation of the director or officer in a meeting of the board of directors or a committee which authorizes the contract or transaction if (i) the material facts as to the relationship or interest and as to the contract or transaction are disclosed or are known to the board of directors or the committee, and the board of directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of disinterested directors, even though the disinterested directors are less than a quorum; (ii) the material facts as to the relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (iii) the contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof or the stockholders.

#### Washington Provisions

The RCW sets forth a safe harbor for transactions between a corporation and one or more of its directors. A conflicting interest transaction may not be enjoined, set aside or give rise to damages if (i) it is approved by a majority of the qualified directors on the board of directors or an authorized committee, but in either case no fewer than two qualified directors; (ii) it is approved by a majority of all qualified shares; or (iii) at the time of commitment, the transaction was fair to the corporation. For purposes of this provision, “qualified director” is one who does not have (a) a conflicting interest respecting the transaction; or (b) a familial, financial, professional or employment relationship with a non-qualified director which relationship would reasonably be expected to exert an influence on the qualified director’s judgment when voting on the transaction. “Qualified shares” are defined generally as shares other than those beneficially owned, or the voting of which is controlled, by a director who has a conflicting interest respecting the transaction.

##### Stock Redemptions and Repurchases

#### Delaware Provisions

Under the DGCL, a Delaware corporation may purchase or redeem its own shares of capital stock, except when the capital of the corporation is impaired or when such purchase or redemption would cause any impairment of the capital of the corporation.

#### Washington Provisions

A Washington corporation may acquire its own shares.

##### Proxies

#### Delaware Provisions

Under the DGCL, a proxy executed by a stockholder will remain valid for a period of three years unless the proxy provides for a longer period.

#### Washington Provisions

Under the RCW, a proxy executed by a shareholder will remain valid for eleven months unless a longer period is expressly provided in the appointment.

##### Consideration for Stock

#### Delaware Provisions

Under the DGCL, a corporation may accept as consideration for its stock a combination of cash, property or past services in an amount not less than the par value of the shares being issued, and a secured promissory note or other binding obligation executed by the subscriber for any balance, the total of which must equal at least the par value of the issued stock, as determined by the board of directors.

#### Washington Provisions

Under the RCW, a corporation may issue its capital stock in return for consideration consisting of any tangible or intangible property or benefit to the corporation, including cash, promissory notes, services performed, contracts for services to be performed, or other securities of the corporation.

##### Shareholders Rights to Examine Books and Records

#### Delaware Provisions

The DGCL provides that any stockholder of record may demand to examine the corporation’s books and records for any proper purpose. If management of the corporation refuses, the stockholder can compel release of the books by court order.

45

#### Washington Provisions

The RCW provides that upon five business days’ notice to the corporation a shareholder is entitled to inspect and copy, during regular business hours at the corporation’s principal office, the corporation’s articles of incorporation, bylaws, minutes of all shareholders’ meetings for the past three years, certain financial statements for the past three years, communications to shareholders within the past three years, list of the names and business addresses of the current directors and officers and the corporation’s most recent annual report delivered to the secretary of state. Upon five business days’ notice, so long as the shareholder’s demand is made in good faith and for a proper purpose, the shareholder describes with reasonable particularity the shareholder’s purpose and the records the shareholder desires to inspect, and the records are directly connected with the shareholder’s purpose, a shareholder may inspect and copy excerpts from minutes of any meeting of the board of directors or other records of actions of the board of directors, accounting records of the corporation and the record of shareholders.

##### Appraisal and Dissenters’ Rights

Under the DGCL and the RCW, shareholders have appraisal or dissenter’s rights, respectively, in the event of certain corporate actions such as a merger. These rights include the right to dissent from voting to approve such corporate action, and demand fair value for the shares of the dissenting shareholder. If a proposed corporate action creating dissenters’ rights is submitted to a vote at a shareholders meeting, a shareholder who wishes to assert dissenters’ rights must (i) deliver to the corporation, before the vote is taken, written notice of his intent to demand payment for his shares if the proposed action is effected, and (ii) not vote his shares in favor of the proposed action. If fair value is unsettled, the DGCL and the RCW provide for the dissenter and the company to petition the Court of Chancery or a superior court of the county in Washington where a corporation’s principal office or registered office is located, respectively. Although appraisal or dissenter’s rights are substantially similar in Delaware and Washington, this discussion is qualified in its entirety by reference to the DGCL and the RCW, which provide more specific provisions and requirements for dissenting shareholders.

##### Dividends

#### Delaware Provisions

The DGCL provides that the corporation may pay dividends out of surplus, out of the corporation’s net profits for the preceding fiscal year, or both, provided that there remains in the stated capital account an amount equal to the par value represented by all shares of the corporation’s stock having a distribution preference.

#### Washington Provisions

The RCW provides that shares may be issued pro rata and without consideration to the corporation’s shareholders as a share dividend. The board of directors may authorize distributions to its shareholders provided that no distribution may be made if after giving it effect, the corporation would not be able to pay its liabilities as they become due in the usual course of business or the corporation’s total assets would be less than the sum of its total liabilities plus the amount that would be needed if the corporation were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution.

##### Corporate Action Without a Shareholder Meeting

#### Delaware Provisions

The DGCL permits corporate action without a meeting of stockholders upon the written consent of the holders of that number of shares necessary to authorize the proposed corporate action being taken, unless the certificate of incorporation or articles of incorporation expressly provide otherwise. The Delaware Charter provides that no action may be taken by the stockholders of the Company except at an annual or special meeting.

#### Washington Provisions

If the corporation is a public company, the RCW only permits action by shareholders without a meeting if the action is taken by all shareholders entitled to vote on the action. The Washington Bylaws provide that any action which could be taken at a meeting of the shareholders may be taken without a meeting if one or more written consents setting forth the action so taken are signed by all shareholders entitled to vote.

46

## Will I have dissenters’ rights as a result of the Reincorporation?

Under the RCW, shareholders of the Company are or may be entitled to assert dissenters’ rights as a result of the proposed Reincorporation. Shareholders who oppose the Reincorporation may be entitled to assert the right to receive payment for the value of their shares as set forth in Chapter 23B.13 of the RCW. A copy of this section is attached hereto as Appendix C to this Proxy Statement. These provisions are very technical in nature and should be carefully reviewed by any shareholder wishing to assert such rights.

A shareholder who wishes to assert dissenters’ rights must (a) deliver to the Company before the vote is taken written notice of the shareholder’s intent to demand payment for the shareholder’s shares if the Reincorporation is effected, and (b) not vote such shares in favor of the Reincorporation. The Company will not treat a vote against this proposal as a notice sufficient to meet such requirements. A vote for this proposal will serve as a waiver of dissenters’ rights pursuant to Chapter 23B.13 of the RCW.

## How will the Reincorporation be implemented?

Subject to shareholder approval at the annual meeting and certain other conditions, the Reincorporation will be effected by means of a merger pursuant to the terms of the Agreement and Plan of Merger, or the Merger Agreement, between AmpliPhi and AmpliPhi Biosciences Corporation, a Delaware corporation, or AmpliPhi Delaware, recently formed solely for the purpose of effecting the Reincorporation. Under the Merger Agreement, AmpliPhi will merge with and into AmpliPhi Delaware and, following the effectiveness of the merger, which we refer to as the Merger, AmpliPhi will cease to exist and AmpliPhi Delaware will become the surviving entity. Upon effectiveness of the Reincorporation, AmpliPhi Delaware will be the successor in interest to AmpliPhi and the shareholders of AmpliPhi will become stockholders of AmpliPhi Delaware.

## What is the timing of the Reincorporation?

If shareholders approve the Reincorporation at the annual meeting, we intend to cause the Reincorporation to become effective as soon as practicable, subject to the completion of certain legal formalities, including obtaining certain consents and approval by third parties. The Reincorporation will become effective upon the filing of a Certificate of Merger or similar document with the Secretary of State of Delaware.

## Does AmpliPhi have the right to abandon the Reincorporation?

Pursuant to the Merger Agreement, AmpliPhi and AmpliPhi Delaware agree to take all actions that Delaware law and Washington law require for AmpliPhi and AmpliPhi Delaware to effect the Reincorporation, subject to the approval of the Reincorporation by the shareholders of AmpliPhi and the sole shareholder of AmpliPhi Delaware.

Notwithstanding the foregoing, the Merger Agreement provides that the Board of Directors may abandon the Reincorporation at any time prior to its consummation if the Board of Directors determines that the Reincorporation is inadvisable for any reason. For example, Delaware or Washington law may be changed to reduce the benefits that we hope to achieve through the Reincorporation, or the costs of operating as a Delaware corporation may be increased, although we do not know of any such changes under consideration. The Merger Agreement may be amended at any time prior to its consummation, either before or after the shareholders have voted to adopt the proposal, subject to applicable law. We will re-solicit shareholder approval of the Reincorporation if the terms of the Merger Agreement are changed in any material respect.

## What will happen to my shares of common stock as a result of the Reincorporation?

On the effective date of the Merger, each outstanding share of common stock of AmpliPhi will be automatically converted into one share of common stock of AmpliPhi Delaware. Any stock certificate representing issued and outstanding shares of common stock of AmpliPhi will continue to represent the same number of shares of common stock of AmpliPhi Delaware.

ANY SHARE CERTIFICATES CURRENTLY ISSUED FOR OUR SHARES WILL AUTOMATICALLY REPRESENT SHARES IN AMPLIPHI DELAWARE UPON COMPLETION OF THE MERGER, AND SHAREHOLDERS WILL NOT BE REQUIRED TO SURRENDER OR EXCHANGE ANY SHARE CERTIFICATES AS A RESULT OF THE REINCORPORATION.

47

## Will the common stock continue to be listed for trading after the Reincorporation?

Our common stock is listed for trading on the NYSE MKT under the ticker symbol “APHB.” After the Reincorporation, AmpliPhi Delaware’s common stock would continue to be traded on the NYSE MKT without interruption, under the same symbol.

## Will the reincorporation impact AmpliPhi Washington’s registration statements with the SEC?

No. The registration statements of AmpliPhi Washington on file with the SEC immediately prior to the Reincorporation will be assumed by AmpliPhi Delaware.

## What will be the impact of the Reincorporation on AmpliPhi’s Employee Benefit and Incentive Compensation Plans?

Each outstanding option and restricted stock unit to purchase or receive shares of our common stock will be converted into an option and restricted stock unit, respectively, to purchase or receive the same number of shares of AmpliPhi Delaware common stock with no other changes in the terms and conditions of such award. Shareholders should note that approval of this proposal would also constitute approval of the assumption by AmpliPhi Delaware of the 2009 Stock Incentive Plan, 2012 Stock Incentive Plan, 2013 Stock Incentive Plan, and, if approved by shareholders at the annual meeting, the 2016 Equity Incentive Plan and the 2016 Employee Stock Purchase Plan. Up to 723,431 shares of common stock remain available for issuance under the 2013 Stock Incentive Plan, and, if approved by shareholders at the annual meeting, up to 2,373,000 shares of common stock may be issued under the 2016 Equity Incentive Plan and up to 120,000 shares of common stock may be issued under the 2016 Employee Stock Purchase Plan. AmpliPhi’s other employee benefit arrangements would also be continued by AmpliPhi Delaware upon the terms and subject to the conditions in effect prior to the Reincorporation.

## Interest of AmpliPhi’s Directors and Executive Officers in the Reincorporation

Our shareholders should be aware that certain of our directors and executive officers may have interests in the transaction that are different from, or in addition to, the interests of the shareholders generally. For example, the Reincorporation may be of benefit to our directors and officers by reducing their potential personal liability and increasing the scope of permitted indemnification, by strengthening directors’ ability to resist a takeover bid, and in other respects. The Board of Directors was aware of these interests and considered them, among other matters, in reaching its decision to approve the Reincorporation and to recommend that our shareholders vote in favor of this proposal.

## Accounting Consequences Associated with the Reincorporation

The consolidated financial condition and results of operations of AmpliPhi Delaware immediately after consummation of the Reincorporation will be substantially identical as those of AmpliPhi immediately prior to the consummation of the Reincorporation. We believe that there will be no material accounting impact as a result of the Reincorporation.

## Certain U.S. Federal Income Tax Consequences

The following discussion summarizes certain U.S. federal income tax consequences of the Reincorporation to holders of our common stock. The discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, regulations promulgated under the Code by the U.S. Treasury Department (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the Internal Revenue Service, or the IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. Such change could materially and adversely affect the tax consequences described below. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described herein. No ruling from the IRS has been or will be sought with respect to any aspect of the transactions described herein.

This discussion is for general information only, and does not purport to discuss all potential tax effects of the Reincorporation. For example, it does not consider the effect of any applicable state, local, or non-U.S. tax laws, or any non-income tax laws (such as estate and gift tax laws). In addition, it does not address all aspects

48

of U.S. federal income taxation that may affect particular holders in light of their particular investment or tax circumstances, including, without limitation, holders subject to special tax rules, such as partnerships, subchapter S corporations or other entities that are fiscally transparent for U.S. federal income tax purposes, banks, financial institutions, tax-exempt entities, insurance companies, regulated investment companies, real estate investment trusts, trusts and estates, dealers in stocks, securities or currencies, traders in securities that have elected to use the mark-to-market method of accounting for their securities, persons holding our common stock as part of an integrated transaction, including a “straddle,” “hedge,” “constructive sale,” or “conversion transaction,” persons whose functional currency for tax purposes is not the U.S. dollar, persons who acquired our common stock pursuant to the exercise of stock options or otherwise as compensation, persons whose common stock constitutes qualified business stock with the meaning of Section 1202 of the Code, and persons who are not “U.S. persons” as defined below. This summary also does not consider any alternative minimum or Medicare “net investment income” tax considerations. Furthermore, this discussion does not address the tax consequences of transactions occurring prior to or after the Reincorporation (whether or not such transactions are in connection with the Reincorporation).

This discussion is directed solely to holders that hold our common stock as capital assets within the meaning of Section 1221 of the Code, which generally means as property held for investment. In addition, the following discussion only addresses “U.S. persons” for U.S. federal income tax purposes, generally defined as beneficial owners of our common stock who are:

| • | Individuals who are citizens or residents of the United States for U.S. federal income tax purposes;

| • | Corporations (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or of any state of the United States or the District of Columbia;

| • | Estates the income of which is subject to U.S. federal income taxation regardless of its source;

| • | Trusts if a court within the United States is able to exercise primary supervision over the administration of any such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust; or

| • | Trusts in existence on August 20, 1996 that have valid elections in effect under applicable Treasury regulations to be treated as U.S. persons.

Holders of our common stock who are not covered by this summary, including partners of partnerships and owners of other pass-through entities holding our capital stock, should consult their own tax advisors.

This discussion does not purport to be a complete analysis of all of the Reincorporation’s tax consequences that may be relevant to holders. We urge you to consult your own tax advisor regarding your particular circumstances and the U.S. federal income and other federal tax consequences to you of the Reincorporation, as well as any tax consequences arising under the laws of any state, local, foreign or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

Subject to the caveats and qualifications noted above, we believe:

| • | The Reincorporation will constitute a tax-free reorganization under Section 368(a) of the Code;

| • | No gain or loss will be recognized by holders on the exchange of their AmpliPhi Washington common stock on receipt of AmpliPhi Delaware common stock pursuant to the Reincorporation;

| • | The aggregate tax basis of AmpliPhi Delaware common stock received by each holder will equal the aggregate tax basis of the AmpliPhi Washington common stock surrendered by such holder in exchange therefor; and

| • | The holding period of the AmpliPhi Delaware common stock received by each holder will include the period during which such holder held the AmpliPhi Washington common stock surrendered in exchange therefor.

49

## Vote Required

Votes “For” the proposal by at least 51% of the outstanding shares of common stock on the record date is required to approve the Reincorporation Proposal. Approval of this Reincorporation Proposal will constitute approval of the Merger Agreement and therefore the Reincorporation itself. A vote in favor of the Reincorporation Proposal is also effectively a vote to approve the form of the Delaware Charter and the Delaware Bylaws. If the shareholders approve the Merger Agreement and the Reincorporation is effected, the Delaware Charter and the Delaware Bylaws will become the certificate of incorporation and bylaws of the surviving corporation.

# The Board of Directors Recommends
a Vote “For” Proposal 4.

# PROPOSAL 5
Approval of the issuance of up to an aggregate of 1,037,053 shares of common stock
as and to the extent required to be issued pursuant to the terms of that certain
Common Stock Issuance Agreement, dated April 8, 2016, by and among the Company and certain
former holders of the Company’s Series B convertible preferred stock

## Background

On April 8, 2016, certain holders (the “Holders”) of over two-thirds of the Company’s then-outstanding shares of Series B convertible preferred stock (“Series B Preferred”) elected to automatically convert all outstanding shares of Series B Preferred into shares of common stock in accordance with Section 4.4.4(b)(ii) of the Company’s Amended and Restated Articles of Incorporation, as amended (the “Conversion”). On April 8, 2016, the Company entered into a Common Stock Issuance Agreement (the “Agreement”) with the Holders, pursuant to which the Holders waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the Conversion in respect of accrued dividends on their former shares of Series B Preferred and waived their registration rights with respect to certain future registration statements that may be filed, and certain future public offerings that may be conducted, by the Company.

As consideration for the foregoing waivers by the Holders, the Company issued the Holders an aggregate of 853,465 shares of common stock (the “Transaction Shares”) in a transaction constituting a private placement, at an effective price per share (taking into consideration the waiver of the accrued dividends) that was less than the greater of the Company’s book or market value per share. Immediately prior to such issuance on April 8, 2016, there were 5,883,503 shares of common stock outstanding. The number of Transaction Shares represented approximately 14.5% of the shares outstanding prior to the issuance of such shares.

Pursuant to Section 713(a) of the NYSE MKT Company Guide, shareholder approval is generally required prior to the issuance of securities in connection with a transaction other than a public offering involving the sale, issuance, or potential issuance by the issuer of common stock (or securities convertible into common stock) equal to 20% or more of presently outstanding stock for less than the greater of book or market value of the stock.

Pursuant to the Agreement, as further consideration for the waivers provided by the Holders described above, the Company agreed that if in the future it conducts one or more bona fide equity financings in which it sells shares of its common stock or preferred stock at a price of less than $4.05 per share (each, a “Dilutive Financing”), the Company will, to the extent permitted by NYSE MKT rules, issue to the Holders, for no additional consideration, a number of additional shares of common stock (“Additional Shares”) based on a specified formula, as described further below. We refer to the foregoing rights as the “Additional Issuance Rights”. Any Additional Shares that the Company issues pursuant to the Additional Issuance Rights would be aggregated with the Transaction Shares for purposes of determining whether the total number of Additional Shares issued equals or exceeds 20% of the Company’s outstanding stock as of immediately prior to the issuance of the Transaction Shares (the “NYSE 20% Cap”). Accordingly, absent shareholder approval, the maximum number of Additional Shares that the Company can issue pursuant to Section 713(a) of the NYSE MKT Company Guide without shareholder approval is 323,235 shares. If the shareholders do not approve this proposal at the annual meeting, the Company could be required to make cash payments to the Holders in lieu of issuing Additional Shares, as described further below.

If the Company conducts a Dilutive Financing, the Holders will be entitled to receive (absent consideration of the NYSE 20% Cap) in the aggregate a number of Additional Shares equal to (A) the product of (x) 1,037,053 multiplied by (y) a fraction, the numerator of which is $4.05 and the denominator of which is the lowest price per share paid by investors in such Dilutive Financing (the “Effective Price”) less (B) 1,037,053 and all Additional Shares issued previously to the Holders pursuant to the Additional Issuance Rights. The Agreement includes a provision intended to limit the Company’s obligation to issue Additional Shares to the extent such Additional Shares would exceed the 20% limit on the number of shares that can be issued without shareholder approval pursuant to Section 713(a) of the NYSE MKT Company Guide. The Company’s obligation to issue Additional Shares as a result of one or more Dilutive Financings may be

51

waived by the Holders of at least 95% of the then-outstanding Transaction Shares, but there can be no assurance that the Holders will elect to do so.

The Company’s obligation to issue Additional Shares in the event of a Dilutive Financing only applies to the lowest priced financing conducted after the date of the Agreement. For example, if the Company completes a Dilutive Financing priced at $3.50 a share followed by a Dilutive Financing priced at $3.75 a share, the obligation to issue Additional Shares would be triggered by the first Dilutive Financing but not the second Dilutive Financing. In addition, the Company’s obligation to issue Additional Shares will expire on June 30, 2018 or at such earlier time as the Company has raised at least $10.0 million in gross proceeds from the sale of its common stock and/or preferred stock in one or more bona fide financings.

## Reason for Seeking Shareholder Approval

Pursuant to the Agreement, the Company agreed to use its commercially reasonable efforts to obtain shareholder approval of the issuance of up to 1,037,053 Additional Shares to the Holders as and to the extent required by the Agreement in connection with one or more Dilutive Financings. If the shareholders approve this proposal, such number of Additional Shares may be issued to the Holders even if the issuance of such shares would, when aggregated with the Transaction Shares, exceed the NYSE 20% Cap. If the shareholders do not approve this proposal, the maximum number of Additional Shares that the Company may issue in satisfaction of the Additional Issuance Rights in accordance with Section 713(a) of the NYSE MKT Company Guide will be 323,235 shares.

If the Company’s shareholders do not approve this proposal at the annual meeting, then in lieu of issuing any Additional Shares that would have been required to be issued to a Holder pursuant to the operation of the Additional Issuance Rights but for the limitations imposed by NYSE 20% Cap (the “Excess Shares”), the Company will, to the extent legally permitted, become obligated to pay to such Holder a cash amount per Excess Share equal to the difference between the lowest price per share paid by investors in such Dilutive Financing and $4.05, less any cash payment per share previously made or obligated to be made to such Holder pursuant to the Agreement (the “Cash Make-Whole”).

## Certain Consequences if the Proposal is Approved or Not Approved

The Company believes the approval of this proposal will provide the Company with increased flexibility to raise financing through the sale of its capital stock at market or negotiated prices in one or more Dilutive Financing transactions by reducing or eliminating the application of the Cash Make-Whole provision.

If the proposal is not approved, the Company may be required to make cash payments to the Holders pursuant to the Cash Make-Whole in connection with one or more Dilutive Financing transactions. If the Cash Make-Whole would be triggered by a proposed Dilutive Financing, the potential payment obligations could make such Dilutive Financing less feasible and financially viable for the Company, particularly if the proceeds to be received by the Company in such financing would not significantly exceed the Cash Make-Whole payments, and thereby jeopardize the Company’s ability to raise capital in a Dilutive Financing that could otherwise provide needed cash resources to the Company. Even if the Company is able to complete a Dilutive Financing, any Cash Make-Whole payments would deplete the Company’s cash resources at a time when the Company’s cash resources may be extremely limited.

The Company’s shareholders will incur dilution of their percentage ownership interest in the Company to the extent the Company issues Additional Shares to the Holders pursuant to the Additional Issuance Rights. The Company’s shareholders will incur greater ownership interest dilution to the extent this proposal is approved and the Company becomes required to issue some or all of the 1,037,053 Additional Shares that are the subject to this proposal, which shares the Company would not otherwise have been permitted to issue pursuant to the NYSE 20% Cap. In addition, because the Additional Shares will be issued for no additional consideration, any such issuance would reduce the net tangible book value per share of the Company. However, to the extent Additional Shares are not issued when otherwise required by the Agreement due to the NYSE 20% Cap, the payments by the Company in satisfaction of the Cash Make-Whole will also reduce the net tangible book value per share of the Company, as well as the overall net tangible book value.

52

## Interest of Certain Persons in the Proposal

One Fund Management Limited as Trustee for Asia Pacific Healthcare Fund II (“One Funds”), an entity affiliated with Jeremy Curnock Cook, the Chairman of the Company’s Board of Directors, is a party to the Agreement as a Holder. The Agreement was approved by the Company’s Audit Committee and no special terms were given to Mr. Cook or One Funds.

## Vote Required

In order for Proposal 5 to be approved, the number of shares that vote “For” the proposal must exceed the number of shares that vote “Against” the proposal. Abstentions will be counted towards the vote total for Proposal 5 and will have the same effect as “Against” votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

The Board of Directors Recommends
a Vote “For” Proposal 5.

53

# Proposal 6
Approval of the issuance by the Company of up to an aggregate of 4,706,000 shares of common stock and/or warrants to purchase common stock in a financing that does not constitute a public offering under NYSE MKT rules, for gross sale proceeds of up to $12,000,000 and at a discount to the then-current market value of the Company’s Common Stock not to exceed 15%

Pursuant to Section 713(a) of the NYSE MKT Company Guide, shareholder approval is generally required prior to the issuance of securities in connection with a transaction other than a public offering involving (each of the following, a “Discounted Private Placement”): (i) the sale, issuance, or potential issuance by the issuer of common stock (or securities convertible into common stock) at a price less than the greater of book or market value which together with sales by officers, directors or principal shareholders of the issuer equals 20% or more of presently outstanding common stock; or (ii) the sale, issuance, or potential issuance by the issuer of common stock (or securities convertible into common stock) equal to 20% or more of presently outstanding stock for less than the greater of book or market value of the stock. The foregoing 20% limitations are referred to in this proposal as the “NYSE 20% Cap”.

The Company is seeking shareholder approval of the potential issuance by the Company in one or more Discounted Private Placement transactions of up to an aggregate of 4,706,000 shares of the Company’s common stock and/or warrants exercisable for common stock, for aggregate proceeds of up to $12 million, at a price per share that is equal to or greater than 85% of the market price per share of common stock as most recently reported on the NYSE MKT prior to the entry into a definitive transaction agreement for the financing, without further shareholder approval. Approval of this proposal at the annual meeting will permit the Company to complete one or more Discounted Private Placements only if the definitive agreement for any such Discounted Private Placement is entered into no later than 90 days following the date of the annual meeting. . Any definitive agreement for a Discounted Private Placement entered into more than 90 days following the date of the annual meeting would again be subject to any shareholder approval required under Section 713(a) of the NYSE MKT Company Guide.

The Company currently anticipates using the proceeds of any Discounted Private Placement approved by the shareholders pursuant to this proposal for general corporate purposes, including manufacturing expenses, clinical trial expenses, research and development expenses and general and administrative expenses.

If the Company issues shares of its common stock or common stock warrants in one or more Discounted Private Placement transactions, existing shareholders will incur dilution of their percentage ownership interest in the Company and may also incur dilution in the value of their investment in the Company depending on the price per share sold in such transaction.

The Company believes that the approval of this proposal will provide the Company with increased flexibility to raise financing through the sale of its capital stock at negotiated prices. The Company currently anticipates that its existing cash resources will be sufficient to fund its planned operations into the third quarter of 2016. As a result, it is critical for the Company to raise additional capital within the next several months. The Company’s ability to raise significant cash proceeds from a registered public offering is limited as a result of the aggregate market value of the Company’s outstanding common stock held by non-affiliates, or public float, being less than $75.0 million as of the date of this proxy statement. The rules of the Securities and Exchange Commission limit the dollar amount of securities the Company may sell under a registration statement on Form S-3 to one-third of the Company’s public float (based on the trading price of the common stock as of a date within 60 days prior to the relevant offering) during any 12-month period for so long as the Company’s public float remains below $75.0 million. In addition, certain registered offerings are not considered to be “public offerings” under the rules of the NYSE MKT, and consequently the NYSE 20% Cap may further limit the Company’s ability to raise capital, even if the offering is registered on Form S-3, so that the Company may not be permitted to raise the amounts otherwise permitted under Form S-3. In addition, completing a registered offering on Form S-1 is a significantly lengthier and generally more expensive process than both a private placement and an offering pursuant to a Form S-3 registration statement. Consequently, the Company is seeking approval of this proposal to provide it with increased financing flexibility and enable it to potentially raise up to an aggregate of $12 million through one or more Discounted Private Placement

54

transactions, which would be in excess of what it could currently raise on Form S-3 or in any offering subject to the NYSE 20% Cap based on the current market value of the common stock as of the date of this proxy statement.

In order for Proposal 6 to be approved, the number of shares that vote “For” the proposal must exceed the number of shares that vote “Against” the proposal. Abstentions will be counted towards the vote total for Proposal 6 and will have the same effect as “Against” votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

The Board of Directors Recommends
a Vote “For” Proposal 6.

This proxy statement shall not constitute an offer to sell or the solicitation of an offer to buy any securities of the Company, nor shall there be any offer, solicitation, or sale of any securities of the Company in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

55

# Proposal 7
Ratification of Selection of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors has selected Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2016 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the shareholders at the annual meeting. Ernst & Young LLP was selected as our independent accountant as of January 20, 2015. Prior to selecting Ernst & Young LLP, PBMares, LLP served as our independent registered public accounting firm, including for the fiscal year ended December 31, 2014. Representatives of Ernst & Young LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. Representatives of PBMares, LLP are not expected to be present at the annual meeting.

Neither the Company’s Bylaws nor other governing documents or law require shareholder ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of Ernst & Young LLP to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its shareholders.

In order for Proposal 7 to be approved, the number of shares that vote “For” the proposal must exceed the number of shares that vote “Against” the proposal. Abstentions will be counted towards the vote total for Proposal 7 and will have the same effect as “Against” votes. Broker non-votes, if any, are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

## Pre-Approval Policies and Procedures

The Audit Committee approves in advance the engagement and fees of the independent registered public accounting firm for all audit services and non-audit services, based upon independence, qualifications and, if applicable, performance. The Audit Committee may form and delegate to subcommittees of one or more members of the Audit Committee the authority to grant pre-approvals for audit and permitted non-audit services, up to specific amounts. All audit services provided by Ernst & Young LLP and PBMares, LLP for the periods presented were pre-approved by the Audit Committee.

## Change in Independent Registered Public Accounting Firm

On January 20, 2015, we dismissed PBMares, LLP as our independent registered public accounting firm. The reports of PBMares, LLP on our financial statements for the year ended December 31, 2014 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to audit scope or accounting principles. The decision to change auditors was approved by the Audit Committee.

During our two most recent fiscal years, and in the interim period ending on the date of our dismissal of PBMares, LLP, we have not had any disagreements with PBMares, LLP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to PBMares LLP’s satisfaction, would have caused them to make reference thereto in their reports on our financial statements for such periods.

During our two most recent fiscal years, and in the interim period ending on the date of our dismissal of PBMares, LLP, there were no reportable events, as defined in Item 304(a)(1)(v) of Regulation S-K. PBMares, LLP provided us with a letter addressed to the SEC confirming PBMares, LLP’s agreement with the foregoing disclosures. A copy of the letter from PBMares, LLP, dated January 22, 2015, is included as Exhibit 16.1 to our Current Report on Form 8-K filed with the SEC on January 23, 2015.

## Ability to Continue as a Going Concern

The report of Ernst & Young LLP on the consolidated financial statements of the Company for the fiscal year ended December 31, 2015, included in the Form 10-K filed with the Securities and Exchange Commission on March 30, 2016 states that the Company has incurred net losses since its inception, has negative operating cash flows and has an accumulated deficit of $362.5 million as of December 31, 2015, $47.0 million of which has been accumulated since January of 2011, when the Company began its focus on bacteriophage development, which raise substantial doubts about the Company’s ability to continue as a going concern. Other than the foregoing, Ernst & Young LLP’s report on the financial statements for the past two years contained no adverse opinion or disclaimer of opinion and was not qualified as to audit scope or accounting principles.

# Executive Officers

The following table sets forth information regarding our executive officers as of the date of this proxy statement.

Name |  | Age |  | Position
M. Scott Salka |  | 54 |  | Chief Executive Officer, Director
Steve R. Martin |  | 55 |  | Chief Financial Officer
Wendy S. Johnson |  | 64 |  | Interim Chief Operating Officer, Director

The following is biographical information for Steve R. Martin, our Chief Financial Officer. The biographical information for our other executive officers, Mr. Salka and Ms. Johnson, is included under Proposal 1.

# Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information regarding beneficial ownership of our capital stock by:

| • | each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;

| • | each of our directors;

| • | each of our named executive officers; and

| • | all of our current executive officers and directors as a group.

The percentage ownership information in the table below is based on 8,242,528 shares of common stock outstanding as of April 30, 2016.

Information with respect to beneficial ownership has been furnished by each director, officer or beneficial owner of more than 5% of our common stock, unless otherwise indicated. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on or before June 29, 2016, which is 60 days after April 30, 2016. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Except as otherwise noted below, the address for each person or entity listed in the table is c/o AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

Under this services agreement, we paid $5,000 per month to The Fahrenheit Group, LLC for Mr. Bosher’s services, up to 20 hours per month, and $300 per hour for any additional services in excess of 20 hours per month.

## Bonus Opportunity

In addition to base salaries, certain of our named executive officers are eligible to receive annual performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for individual achievement towards these goals. The performance-based bonus a named executive officer may be eligible to receive is generally based on the extent to which we achieve the specified corporate goals that our Board of Directors or Compensation Committee establishes. At the end of the year, the Board of Directors and/or Compensation Committee reviews our performance against the established corporate goals and approves the extent to which we achieved such goals. In addition, we may award a named executive officer a discretionary cash or equity bonus, if our Board of Directors or Compensation Committee determines appropriate based on the circumstances.

The Board of Directors and/or Compensation Committee generally will consider each executive officer’s individual contributions towards reaching our corporate goals and may also establish specific individual goals for our executive officers as it determines appropriate. There is no minimum bonus percentage or amount established for the named executive officers and, as a result, the bonus amounts vary based on corporate and individual performance, as applicable. Under the terms of his offer letter agreement described below, Mr. Salka is eligible to receive an annual performance-based bonus for 2015 equal to, at target, 40% of his annual salary based on our achievement of certain performance goals, pro-rated for Mr. Salka’s services during 2015. Under the terms of her consulting agreement described below, Ms. Johnson is eligible to receive up to $200,000 in cash bonus payments upon achievement of specific goals relating to dosing the first patient in the first and second clinical trials utilizing our drug product. Mr. Bosher is not entitled to any specific target or maximum bonus for company or individual performance in 2015.

Mr. Salka’s 2015 bonus was based entirely on corporate goals relating to our clinical trial progress, manufacturing capabilities being established, certain organizational achievements and for listing our company on a major stock exchange.

64

No specific corporate or individual goals were established for Mr. Bosher for 2015.

Ms. Johnson was eligible to earn a bonus of $175,000 upon dosing of the first patient in the first clinical trial utilizing our drug product in 2015 (or alternatively, a bonus of $75,000 if such milestone was met after 2015 and prior to March 31, 2016) and a bonus of $25,000 upon dosing of the first patient in the second clinical trial utilizing our drug product before March 31, 2016.

In January 2016, the Compensation Committee reviewed the corporate performance goals for Mr. Salka and determined that on an overall basis, we had achieved 50% of such goals for 2015, based on the evaluation of the results by the Compensation Committee and considering the importance of each goal to us. The Compensation Committee assessed the goals established for Ms. Johnson’s bonus and determined that she had not met the goals in 2015 because no patients were dosed in 2015. However, the Compensation Committee awarded Ms. Johnson a discretionary bonus of $25,000, in recognition of significant progress towards the goal which was supported by the patient screenings which occurred in 2015, although no patients were dosed until January 2016. Ms. Johnson has earned performance bonuses in 2016 based on the achievement of the established goals and additional achievements in the first quarter of 2016.

## Equity-Based Awards

Our equity-based incentive awards are designed to align our interests with those of our employees and consultants, including our named executive officers. Our Board of Directors or our Compensation Committee approves equity grants. Vesting of equity awards is generally tied to continuous service with us and serves as an additional retention measure. Our executives may be awarded an initial new hire grant upon commencement of service and may receive additional grants, as the Board of Directors or Compensation Committee determines appropriate, in order to incentivize and/or reward such executives.

We have traditionally granted stock options to our named executive officers under our equity incentive plans, the terms of which are described below under “— Equity Benefit Plans.”

In August 2015, our Board of Directors granted an option to purchase 399,716 shares of common stock to Mr. Salka at a per share exercise price of $9.45.

## Equity Benefit Plans

### 2013 Stock Incentive Plan

Our 2013 Stock Incentive Plan, or the 2013 Plan, was first approved by our Board of Directors in December 2013 and approved by our shareholders in February 2014, and subsequently amended by our Board of Directors and shareholders effective in August 2015. The 2013 Plan replaces the Targeted Genetics Corporation Stock Incentive Plan and the 2012 Stock Incentive Plan.

As of December 31, 2015, there were outstanding options to purchase 673,169 shares of common stock and 723,431 shares of common stock remaining available for the grant of new awards under the 2013 Plan, subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

The 2013 Plan permits the granting of stock options (both options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and options that do not so qualify), restricted stock, restricted stock units, and performance-based awards. The exercise price of each stock option will be determined by our plan administrator but may not be less than 100% of the fair market value of our common stock on the date of grant or, in the case of an incentive stock option granted to a 10% owner, less than 110% of the fair market value of our common stock on the date of grant. The term of each stock option will be fixed by the plan administrator and may not exceed 10 years from the date of grant. The plan administrator will determine at what time or times each option may be exercised.

Under the terms of the 2013 Plan, an option may be exercised following the cessation of a participant’s service with us only to the extent provided in the applicable option agreement. If a participant’s service relationship with us or any of our affiliates ceases for any reason other than disability or death, the participant may generally exercise any vested options for a period of three months following the cessation of service. If a participant’s service relationship with us or any of our affiliates ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested options for a period of 12 months. In no event may an option be exercised beyond the expiration of its term.

68

The 2013 Plan provides that upon the effectiveness of a corporate transaction (as such term is defined in the 2013 Plan) in the event that all awards are not affirmed by us or assumed by the successor entity, all awards granted under the 2013 Plan shall terminate. In addition, in connection with a corporate transaction or change in control (as such term is defined in the 2013 Plan) the plan administrator may provide the full or partial automatic vesting and exercisability of one or more outstanding unvested awards under the 2013 Plan and the release from restrictions on transfer or forfeiture rights of such awards in connection with such transaction, on such terms and conditions as the plan administrator may specify.

Our Board of Directors may amend or terminate the 2013 Plan at any time. The plan administrator may amend the terms of any outstanding award granted under the 2013 Plan, but no such action may adversely affect the holder’s rights under an outstanding award without the holder’s consent. Certain amendments to the 2013 Plan require the approval of our shareholders. No awards may be granted under the 2013 Plan after the date that is 10 years from the date of adoption by our Board of Directors.

### 2009 Targeted Genetics Stock Incentive Plan and 2012 Stock Incentive Plan

Our Board of Directors and shareholders adopted the 2009 Targeted Genetics Stock Incentive Plan in March 2009. Our Board of Directors adopted our 2012 Stock Incentive Plan in October 2012. There are no shares of common stock remaining for future awards under the 2009 Targeted Genetics Stock Incentive Plan and the 2012 Stock Incentive Plan. We refer to the 2009 Targeted Genetics Stock Incentive Plan and the 2012 Stock Incentive Plan together as the Former Plans.

The Former Plans provide that upon the effectiveness of a corporate transaction (as such term is defined in each of the Former Plans) in the event that all awards are not assumed or continued or substituted by the successor entity, all awards granted under the Former Plans shall terminate. In addition, in connection with a corporate transaction, the plan administrator may provide the full automatic vesting and exercisability of one or more outstanding unvested awards under the Former Plans in connection with a corporate transaction, on such terms and conditions as the plan administrator may specify. Furthermore, in connection with a change in control (as such term is defined in each of the Former Plans), the Former Plans provide for the full automatic vesting and exercisability of any outstanding unvested awards held by certain “key service providers,” which under the terms of the Former Plans is defined as any employee, director or consultant who has been designated as a key service provider by the plan administrator, in the event that any such awards are not assumed or continued or substituted by the successor entity.

Our Board of Directors may amend or terminate the Former Plans at any time. Our Board of Directors may also amend the terms of any outstanding award, provided that no amendment to an award may materially impair any of the rights of a participant under any awards previously granted without his or her written consent.

# Transactions With Related Persons

## Related-Person Transactions policy and Procedures

We have adopted a written related-person transactions policy that sets forth our policies and procedures regarding the identification, review, consideration and oversight of “related-person transactions.” For purposes of our policy only, a “related-person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we and any “related person” are participants involving an amount that exceeds $120,000 (or such lower threshold as may be applicable to us from time to time pursuant to the rules and regulations of the SEC or the NYSE MKT).

Transactions involving compensation for services provided to us by an employee, consultant or director are not considered related-person transactions under this policy. A related person is any executive officer, director or a holder of more than five percent of our common stock, including any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board of Directors) for approval. The presentation must include a description of, among other things, the material facts, the direct and indirect interests of the related persons, the benefits of the transaction to us and whether any alternative transactions are available. To identify related-person transactions in advance, we rely on information supplied by our executive officers, directors and certain significant shareholders. In considering related-person transactions, our Audit Committee or other independent body of our Board of Directors takes into account the relevant available facts and circumstances including, but not limited to:

| • | the risks, costs and benefits to us;

| • | the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

| • | the terms of the transaction;

| • | the availability of other sources for comparable services or products; and

| • | the terms available to or from, as the case may be, unrelated third parties.

In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval.

## Certain Related-Person Transactions

The following includes a summary of transactions since January 1, 2014 to which we have been a party, in which the amount involved in the transaction exceeded the lesser of $120,000 or one percent of the average of our total assets at year end for the last two completed fiscal years, and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which are described in the sections above entitled “Executive Compensation” and “Non-Employee Director Compensation.”

## Sale of Common Stock

In March 2015, in connection with a private placement of our common stock, we sold an aggregate of 68,455 shares and 17,113 shares underlying warrants to One Fund Management Limited as Trustee for Asia Pacific Healthcare Fund II (“One Funds”), which is also known as Phillip Asset Management Limited as Trustee for Asia Pacific Healthcare Fund II, or Phillip Asset Management. Jeremy Curnock Cook, our then-interim Chief Executive Officer and the current chairman of our Board of Directors, is a Managing Director and holds an ownership interest in Bioscience Managers Pty Ltd. Phillip Asset Management Limited is 100% owned by Phillip Capital Holdings Ltd., an Australian stockbroker. Phillip Asset Management holds all shares in its capacity as trustee for Bioscience Managers Pty Ltd.

72

In addition, in connection with the March 2015 private placement, we sold an aggregate of 278,788 shares and 69,697 shares underlying warrants to Intrexon Corporation. Randal J. Kirk, directly and through certain affiliates, has voting and dispositive power over a majority of the outstanding capital stock of Intrexon Corporation. Randal J. Kirk is also deemed a holder of more than five percent of the shares of our common stock, as described in the section entitled “Security Ownership of Certain Beneficial Owners and Management and Related Shareholder Matters”. In connection with the March 2015 private placement, we entered into a registration rights agreement with Intrexon and certain other purchasers in the private placement, pursuant to which we registered for resale on Form S-1 (File No. 333-203454) 824,848 shares of common stock (on a post-August 2015 reverse split basis) held or issuable upon exercise of warrants by Intrexon.

## Exclusive Channel Collaboration

Pursuant to the that certain Exclusive Channel Collaboration Agreement, dated as of March 29, 2013 with Intrexon Corporation, which we refer to as the ECC Agreement, we agreed to pay Intrexon Corporation royalties as a percentage in the upper-single digits of the net product sales of a product developed under the collaboration, and may also pay up to $7.5 million in aggregate milestone payments for each product developed. Intrexon Corporation owns more than five percent of our common stock. On April 13, 2016, we provided written notice to Intrexon Corporation of our election to voluntarily terminate the ECC Agreement. The effective date of termination will be 90 days following delivery of the termination notice. We will not incur any early termination penalties as a result of the termination of the ECC Agreement.

## Common Stock Issuance

On April 8, 2016, we entered into a Common Stock Issuance Agreement, or the Stock Issuance Agreement, with certain former holders of our Series B convertible preferred stock, pursuant to which we agreed to issue the former holders an aggregate of 853,465 shares of our Common Stock. Pursuant to the Stock Issuance Agreement, the Company and the holders party thereto also agreed to amend certain warrants to purchase Common Stock issued to such holders in the private placement of Series B convertible preferred stock in June 2013 and/or July 2013, in order to reduce the exercise price of such warrants from $7.00 per share to $4.05 per share and extend the expiration date thereof from June 26, 2018 to March 31, 2021. As consideration for the transactions described above, such holders waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the conversion of all outstanding shares of Series B redeemable convertible preferred stock into shares of common stock on April 8, 2016, or the Series B Conversion, in respect of accrued dividends on their former shares of Series B convertible preferred stock. Such holders also waived their registration rights with respect to certain future registration statements that may be filed, and certain future public offerings that may be conducted, by us.

Pursuant to the Stock Issuance Agreement, we agreed to seek shareholder approval of the issuance of up to 1,037,053 shares of Common Stock to the holders in the future in connection with one or more dilutive financings, as set forth in further detail in Proposal 5 to this proxy statement. To the extent we are not permitted by applicable NYSE MKT rules to issue any additional shares of Common Stock that would otherwise be required to be issued pursuant to the terms of the Stock Issuance Agreement as a result of a dilutive financing, including without limitation if Proposal 5 detailed under this proxy statement is not approved, we have agreed to pay the holders a cash payment equal to the difference between the price per share in such dilutive financing and $4.05 for each share issued to the holders pursuant to the Series B Conversion.

Pendinas Limited and One Funds, each beneficial owners of more than 5% of our capital stock, participated in this transaction and are parties to the Stock Issuance Agreement. One Funds is affiliated with Jeremy Curnock Cook, the Chairman of our Board of Directors.

## Employment Agreements

We have entered into compensatory arrangements with our executive officers, as more fully described in the section above entitled “Executive Compensation.”

## Stock Options Granted to Executive Officers and Directors

We have granted stock options to our executive officers and directors, as more fully described in the sections above entitled “Executive Compensation” and “Non-Employee Director Compensation.”

73

## Indemnification Agreements

We have entered, and intend to continue to enter, into separate indemnification agreements with each of our directors and executive officers, as described in the sections above entitled “Executive Compensation” and “Non-Employee Director Compensation.”

# Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for annual meeting materials with respect to two or more shareholders sharing the same address by delivering a single set of annual meeting materials addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for companies.

This year, a number of brokers with account holders who are AmpliPhi shareholders will be “householding” the Company’s proxy materials. A single set of annual meeting materials will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of annual meeting materials, please notify your broker or AmpliPhi. Direct your written request to AmpliPhi Biosciences Corporation, Attn: Investor Relations, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130 or contact Matt Dansey at (858) 800-4869. Shareholders who currently receive multiple copies of the annual meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

74

# Other Matters

The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

By Order of the Board of Directors,

Jeremy Curnock Cook
Chairman of the Board of Directors

San Diego, California
May 20, 2016

A copy of the Company’s Annual Report to the Securities and Exchange Commission on Form 10-K for the fiscal year ended December 31, 2015 is available without charge upon written request to: Secretary, AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

All Awards granted on or after 12:01 a.m. Pacific Time on the Effective Date will be granted under this Plan. All stock awards granted under the 2013 Plan or under the 2009 Targeted Genetics Stock Incentive Plan or the AmpliPhi Biosciences Corporation 2012 Stock Incentive Plan (collectively, with the 2013 Plan, the “Prior Plans”), will remain subject to the terms of the Prior Plans.

Instead, that number of shares of Common Stock equal to the 2013 Plan’s Available Reserve will be added to the Share Reserve (as further described in Section 3(a) below) and will be immediately available for grants and issuance pursuant to Stock Awards hereunder, up to the maximum number set forth in Section 3(a) below.

(ii) In addition, from and after 12:01 a.m. Pacific Time on the Effective Date, any shares subject, at such time, to outstanding stock awards granted under the Prior Plans that (i) expire or terminate for any reason prior to exercise or settlement; (ii) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company; or (iii) are reacquired, withheld (or not issued) to satisfy a tax withholding obligation in connection with an award or to satisfy the purchase price or exercise price of a stock award (such shares the “Returning Shares ”) will immediately be added to the Share Reserve (as further described in Section 3(a) below) as and when such shares become Returning Shares, up to the maximum number set forth in Section 3(a) below.

(b) Eligible Award Recipients. Employees, Directors and Consultants are eligible to receive Awards.

(c) Available Awards. The Plan provides for the grant of the following Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights, (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards, (vii) Performance Cash Awards, and (viii) Other Stock Awards.

(d) Purpose. The Plan, through the grant of Awards, is intended to help the Company secure and retain the services of eligible award recipients, provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate, and provide a means by which the eligible recipients may benefit from increases in value of the Common Stock.

## 2. Administration.

(a) Administration by Board. The Board will administer the Plan. The Board may delegate administration of the Plan to a Committee or Committees, as provided in Section 2(c).

(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine: (A) who will be granted Awards; (B) when and how each Award will be granted; (C) what type of Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or Common Stock under the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value applicable to a Stock Award.

A-1

(ii) To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for administration of the Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement or in the written terms of a Performance Cash Award, in a manner and to the extent it will deem necessary or expedient to make the Plan or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv) To accelerate, in whole or in part, the time at which an Award may be exercised or vest (or the time at which cash or shares of Common Stock may be issued in settlement thereof).

(v) To suspend or terminate the Plan at any time. Except as otherwise provided in the Plan or an Award Agreement, suspension or termination of the Plan will not materially impair a Participant’s rights under the Participant’s then-outstanding Award without the Participant’s written consent, except as provided in subsection (viii) below.

(vi) To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or bringing the Plan or Awards granted under the Plan into compliance with the requirements for Incentive Stock Options or ensuring that they are exempt from, or compliant with, the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. If required by applicable law or listing requirements, and except as provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek shareholder approval of any amendment of the Plan that (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan, (D) materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (E) materially extends the term of the Plan, or (F) materially expands the types of Awards available for issuance under the Plan. Except as otherwise provided in the Plan or an Award Agreement, no amendment of the Plan will materially impair a Participant’s rights under an outstanding Award without the Participant’s written consent.

(vii) To submit any amendment to the Plan for shareholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to Covered Employees, (B) Section 422 of the Code regarding “incentive stock options” or (C) Rule 16b-3.

(viii) To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided, however, that a Participant’s rights under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and (B) such Participant consents in writing. Notwithstanding the foregoing, (1) a Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards without the affected Participant’s consent (A) to maintain the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (B) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award solely because it impairs the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (C) to clarify the manner of exemption from, or to bring the Award into compliance with, Section 409A of the Code; or (D) to comply with other applicable laws or listing requirements.

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards.

A-2

(x) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Award Agreement that are required for compliance with the laws of the relevant foreign jurisdiction).

(xi) To effect, with the consent of any adversely affected Participant, (A) the reduction of the exercise, purchase or strike price of any outstanding Stock Award; (B) the cancellation of any outstanding Stock Award and the grant in substitution therefor of a new (1) Option or SAR, (2) Restricted Stock Award, (3) Restricted Stock Unit Award, (4) Other Stock Award, (5) cash and/or (6) other valuable consideration determined by the Board, in its sole discretion, with any such substituted award (x) covering the same or a different number of shares of Common Stock as the cancelled Stock Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally accepted accounting principles.

(c) Delegation to Committee.

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee, as applicable). Any delegation of administrative powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as applicable). The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated.

(ii) Section 162(m) and Rule 16b-3 Compliance. The Committee may consist solely of two or more Outside Directors, in accordance with Section 162(m) of the Code, or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3.

(d) Delegation to an Officer. To the extent permissible under applicable law, the Board may delegate to one (1) or more Officers the authority to do one or both of the following (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other Stock Awards) and, to the extent permitted by applicable law, the terms of such Awards, and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation will specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself. Any such Stock Awards will be granted on the form of Stock Award Agreement most recently approved for use by the Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may not delegate authority to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 13(y)(iii) below.

(e) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

## 3. Shares Subject to the Plan.

(a) Share Reserve. Subject to Section 9(a) relating to Capitalization Adjustments, and the following sentence regarding the annual increase, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards will not exceed 2,373,000 shares (the “Share Reserve”), which number is the sum of (i) 1,000,000 new shares, plus (ii) the number of shares subject to the 2013 Plan’s Available Reserve, plus (iii) the number of shares that are Returning Shares, as such shares become available from time to time.

A-3

In addition, the Share Reserve will automatically increase on January 1st of each year, for a period of not more than ten years, commencing on January 1st of the year following the year in which the Effective Date occurs and ending on (and including) January 1, 2026, in an amount equal to 5% of the total number of shares of Capital Stock outstanding on December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence.

For clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule 5635(c), NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under the Plan.

(b) Reversion of Shares to the Share Reserve. If a Stock Award or any portion thereof (i) expires or otherwise terminates without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for issuance under the Plan. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or repurchased will revert to and again become available for issuance under the Plan. Any shares reacquired by the Company in satisfaction of tax withholding obligations on a Stock Award or as consideration for the exercise or purchase price of a Stock Award will again become available for issuance under the Plan.

(c) Incentive Stock Option Limit. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be 4,746,000 shares of Common Stock.

(d) Section 162(m) Limitations. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, at such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, the following limitations shall apply.

(i) A maximum of 1,000,000 shares of Common Stock subject to Options, SARs and Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least 100% of the Fair Market Value on the date the Stock Award is granted may be granted to any one Participant during any one calendar year. Notwithstanding the foregoing, if any additional Options, SARs or Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least 100% of the Fair Market Value on the date the Stock Award are granted to any Participant during any calendar year, compensation attributable to the exercise of such additional Stock Awards will not satisfy the requirements to be considered “qualified performance-based compensation” under Section 162(m) of the Code unless such additional Stock Award is approved by the Company’s shareholders.

(ii) A maximum of 1,000,000 shares of Common Stock subject to Performance Stock Awards may be granted to any one Participant during any one calendar year (whether the grant, vesting or exercise is contingent upon the attainment during the Performance Period of the Performance Goals).

(iii) A maximum of $2,000,000 may be granted as a Performance Cash Award to any one Participant during any one calendar year.

(e) Limitation on Grants to Non-Employee Directors. The (i) maximum number of shares of Common Stock subject to Stock Awards granted under the Plan or otherwise during any one calendar year (beginning with the 2016 calendar year) to any Non-Employee Director, taken together with the (ii) cash fees paid by the Company to such Non-Employee Director during such calendar year, and in both cases for service on the Board, will not exceed $375,000 in total value (calculating the value of any such Stock Awards based on the grant date fair value of such Stock Awards for financial reporting purposes), or, with respect to the

A-4

calendar year in which a Non-Employee Director is first appointed or elected to the Board, $783,000. The Board may make exceptions to the applicable limit in this Section 3(e) for individual Non-Employee Directors in extraordinary circumstances (for example, to compensate such individual for interim service in the capacity of an officer of the Company), as the Board may determine in its discretion, provided that the Non-Employee Director receiving such additional compensation may not participate in the decision to award such compensation.

(f) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.

## 4. Eligibility.

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a “parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants; provided, however, that Stock Awards may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405 of the Securities Act, unless (i) the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a corporate transaction such as a spin off transaction), (ii) the Company, in consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from Section 409A of the Code, or (iii) the Company, in consultation with its legal counsel, has determined that such Stock Awards comply with the distribution requirements of Section 409A of the Code.

(b) Ten Percent Shareholders. A Ten Percent Shareholder will not be granted an Incentive Stock Option unless the exercise price of such Option is at least 110% of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five years from the date of grant.

## 5. Provisions Relating to Options and Stock Appreciation Rights.

Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for shares of Common Stock purchased on exercise of each type of Option. If an Option is not specifically designated as an Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Award Agreement will conform to (through incorporation of provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions:

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Shareholders, no Option or SAR will be exercisable after the expiration of ten years from the date of its grant or such shorter period specified in the Award Agreement.

(b) Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Shareholders, the exercise or strike price of each Option or SAR will be not less than 100% of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than 100% of the Fair Market Value of the Common Stock subject to the Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the Code. Each SAR will be denominated in shares of Common Stock equivalents.

(c) Purchase Price for Options. The purchase price of Common Stock acquired pursuant to the exercise of an Option may be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board will have the authority to grant Options that do not permit all of the following methods of payment

A-5

(or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of payment. The permitted methods of payment are as follows:

(i) by cash, check, bank draft or money order payable to the Company;

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds;

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock;

(iv) if an Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company will accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of Common Stock will no longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or

(v) in any other form of legal consideration that may be acceptable to the Board and specified in the applicable Award Agreement.

(d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to which the Participant is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation distribution may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Award Agreement evidencing such SAR.

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of Options and SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply:

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (or pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and securities laws. Except as explicitly provided in the Plan, neither an Option nor a SAR may be transferred for consideration.

(ii) Domestic Relations Orders. Subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b)(2). If an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer.

A-6

(iii) Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the death of the Participant, will thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, upon the death of the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent with the provisions of applicable laws.

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of Common Stock as to which an Option or SAR may be exercised.

(g) Termination of Continuous Service. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than upon the Participant’s death or Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) within the period of time ending on the earlier of (i) the date three months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement), and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR will terminate.

(h) Extension of Termination Date. If the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of time (that need not be consecutive) equal to the applicable post termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received on exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a period of months (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement.

(i) Disability of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date 12 months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR (as applicable) will terminate.

A-7

(j) Death of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any) specified in the Award Agreement for exercisability after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of (i) the date 18 months following the date of death (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the applicable time frame, the Option or SAR (as applicable) will terminate.

(k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Agreement or other individual written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate immediately upon such Participant’s termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service.

(l) Non-Exempt Employees. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or (iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement in another agreement between the Participant and the Company, or, if no such definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the extent permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt from the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Stock Awards and are hereby incorporated by reference into such Stock Award Agreements.

## 6. Provisions of Stock Awards other than Options and SARs.

(a) Restricted Stock Awards. Each Restricted Stock Award Agreement will be in such form and will contain such terms and conditions as the Board will deem appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock may be (x) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical. Each Restricted Stock Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(i) Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash, check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law.

A-8

(ii) Vesting. Shares of Common Stock awarded under the Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board.

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award Agreement.

(iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement.

(v) Dividends. A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate.

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and conditions as the Board will deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical. Each Restricted Stock Unit Award Agreement will conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions:

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law.

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate.

(iii) Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement.

(iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award.

(v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate.

(vi) Termination of Participant’s Continuous Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service.

(c) Performance Awards.

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award (covering a number of shares not in excess of that set forth in Section 3(d) above) that is payable (including that may be granted, may vest or may be exercised) contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the Participant’s completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board), in its sole discretion. In addition, to the extent permitted by applicable law and the applicable Award Agreement, the Board may determine that cash may be used in payment of Performance Stock Awards.

(ii) Performance Cash Awards. A Performance Cash Award is a cash award (for a dollar value not in excess of that set forth in Section 3(d) above) that is payable contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service. At the time of grant of a Performance Cash Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board), in its sole discretion. The Board may specify the form of payment of Performance Cash Awards, which may be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other property.

(iii) Board Discretion. The Board retains the discretion to reduce or eliminate the compensation or economic benefit due upon attainment of Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period. Partial achievement of the specified criteria may result in the payment or vesting corresponding to the degree of achievement as specified in the Stock Award Agreement or the written terms of a Performance Cash Award.

(iv) Section 162(m) Compliance. Unless otherwise permitted in compliance with the requirements of Section 162(m) of the Code with respect to an Award intended to qualify as “performance-based compensation” thereunder, the Committee will establish the Performance Goals applicable to, and the formula for calculating the amount payable under, the Award no later than the earlier of (a) the date 90 days after the commencement of the applicable Performance Period, and (b) the date on which 25% of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee will certify the extent to which any Performance Goals and any other material terms under such Award have been satisfied (other than in cases where such Performance Goals relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction of, or completion of any Performance Goals, the number of shares of Common Stock, Options, cash or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Performance Goals may be reduced by the Committee on the basis of such further considerations as the Committee, in its sole discretion, will determine.

(d) Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board will have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards.

A-10

## 7. Covenants of the Company.

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to satisfy then-outstanding Awards.

(b) Securities Law Compliance. The Company will seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock pursuant to the Award if such grant or issuance would be in violation of any applicable securities law.

(c) No Obligation to Notify or Minimize Taxes. The Company will have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award.

## 8. Miscellaneous.

(a) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Awards will constitute general funds of the Company.

(b) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the papering of the Award Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.

(c) Shareholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Award pursuant to its terms, and (ii) the issuance of the Common Stock subject to such Award has been entered into the books and records of the Company.

(d) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

(e) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to

A-11

vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended.

(f) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds $100,000 (or such other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

(g) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that such Participant is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Award has been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

(h) Withholding Obligations. Unless prohibited by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award Agreement.

(i) Electronic Delivery. Any reference herein to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access).

(j) Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive

A-12

payments, including lump sum payments, following the Participant’s termination of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law.

(k) Compliance with Section 409A of the Code. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A of the Code, and, to the extent not so exempt, in compliance with Section 409A of the Code. If the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six months following the date of such Participant’s “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule.

(l) Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of an event constituting Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company.

## 9. Adjustments upon Changes in Common Stock; Other Corporate Events.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 3(c), (iii) the class(es) and maximum number of securities that may be awarded to any person pursuant to Sections 3(d), and (iv) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive.

(b) Dissolution. Except as otherwise provided in the Stock Award Agreement, in the event of a Dissolution of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such Dissolution, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service; provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the Dissolution is completed but contingent on its completion.

A-13

(c) Transactions. The following provisions shall apply to Stock Awards in the event of a Transaction unless otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time of grant of a Stock Award. In the event of a Transaction, then, notwithstanding any other provision of the Plan, the Board shall take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the Transaction:

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to acquire the same consideration paid to the shareholders of the Company pursuant to the Transaction);

(ii) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company);

(iii) accelerate the vesting, in whole or in part, of the Stock Award (and, if applicable, the time at which the Stock Award may be exercised) to a date prior to the effective time of such Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five days prior to the effective date of the Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Transaction;

(iv) arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Stock Award;

(v) cancel or arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and

(vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value of the property the Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Transaction, over (B) any exercise price payable by such holder in connection with such exercise. For clarity, this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of Common Stock in connection with the Transaction is delayed as a result of escrows, earn outs, holdbacks or other contingencies.

The Board need not take the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. The Board may take different actions with respect to the vested and unvested portions of a Stock Award.

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration will occur.

## 10. Plan Term; Earlier Termination or Suspension of the Plan.

The Board may suspend or terminate the Plan at any time. No Incentive Stock Options may be granted after the tenth anniversary of the earlier of (i) the date the Plan is adopted by the Board (the “Adoption Date”), or (ii) the date the Plan is approved by the shareholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated. Suspension or termination of the Plan will not impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant or as otherwise permitted in the Plan.

## 11. Existence of the Plan.

The Plan will become effective on the Effective Date.

A-14

## 12. Choice of Law.

The law of the State of Delaware will govern all questions concerning the construction, validity and interpretation of this Plan, without regard to that state’s conflict of laws rules.

13. Definitions. As used in the Plan, the following definitions will apply to the capitalized terms indicated below:

(a) “Affiliate” means, at the time of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 of the Securities Act. The Board will have the authority to determine the time or times at which “parent” or “subsidiary” status is determined within the foregoing definition.

(b) “Award” means a Stock Award or a Performance Cash Award.

(c) “Award Agreement” means a written agreement between the Company and a Participant evidencing the terms and conditions of an Award.

(d) “Board” means the Board of Directors of the Company.

(e) “Capital Stock” means each and every class of common stock of the Company, regardless of the number of votes per share.

(f) “Capitalization Adjustment” means any change that is made in, or other events that occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the Adoption Date without the receipt of consideration by the Company through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment.

(g) “Cause” shall have the meaning ascribed to such term in any written agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s commission of any felony or any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (ii) such Participant’s attempted commission of, or participation in, a fraud or act of dishonesty against the Company; (iii) such Participant’s intentional, material violation of any contract or agreement between the Participant and the Company or of any statutory duty owed to the Company; (iv) such Participant’s unauthorized use or disclosure of the Company’s confidential information or trade secrets; or (v) such Participant’s gross misconduct. The determination that a termination of the Participant’s Continuous Service is either for Cause or without Cause shall be made by the Company, in its sole discretion. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant shall have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose.

(h) “Change in Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events:

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities, (C) on account of the acquisition of securities of the Company by any individual who is, on the Adoption Date, either an executive officer or a Director (either, a “Legacy Investor”) and/or any entity in which a Legacy Investor has a direct or indirect interest (whether in the form of voting rights or participation in profits or capital contributions) of more

A-15

than 50% (collectively, the “Legacy Entities”) or on account of the Legacy Entities continuing to hold shares that come to represent more than 50% of the combined voting power of the Company’s then outstanding securities as a result of the conversion of any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share pursuant to the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation; or (D) solely because the level of Ownership held by any Exchange Act Person (the “ Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to occur;

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of such merger, consolidation or similar transaction, the shareholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction; provided, however, that a merger, consolidation or similar transaction will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the surviving Entity or its parent are owned by the Legacy Entities;

(iii) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities of which are Owned by shareholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease, license or other disposition; provided, however, that a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the acquiring Entity or its parent are owned by the Legacy Entities;

(iv) the shareholders of the Company approve or the Board approves a plan of complete dissolution or liquidation of the Company, or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; or

(v) individuals who, on the date the Plan is adopted by the Board, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board.

Notwithstanding the foregoing definition or any other provision of the Plan, the term Change in Control will not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company and the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant will supersede the foregoing

A-16

definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition will apply.

(i) “Code” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder.

(j) “Committee” means a committee of one or more Directors to whom authority has been delegated by the Board in accordance with Section 2(c).

(k) “Common Stock” means the common stock of the Company, having one vote per share.

(l) “Company” means AmpliPhi Biosciences Corporation.

(m) “Consultant” means any person, including an advisor, who is (i) engaged by the Company or an Affiliate to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person.

(n) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law.

(o) “Corporate Transaction” means the consummation, in a single transaction or in a series of related transactions, of any one or more of the following events:

(i) a sale or other disposition of all or substantially all, as determined by the Board, in its sole discretion, of the consolidated assets of the Company and its Subsidiaries;

(ii) a sale or other disposition of more than 50% of the outstanding securities of the Company;

(iii) a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

(iv) a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or otherwise.

(p) “Covered Employee” will have the meaning provided in Section 162(m)(3) of the Code.

(q) “Director” means a member of the Board.

A-17

(r) “Disability” means, with respect to a Participant, the inability of such Participant to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months, as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined by the Board on the basis of such medical evidence as the Board deems warranted under the circumstances.

(s) “Dissolution” means when the Company, after having executed a certificate of dissolution with the State of Delaware (or other applicable state), has completely wound up its affairs. Conversion of the Company into a Limited Liability Company (or any other pass-through entity) will not be considered a “Dissolution” for purposes of the Plan.

(t) “Effective Date” means the date of the Company shareholders approve this Plan, which is the date of the annual meeting of shareholders of the Company held on [June 20, 2016] provided this Plan is approved by the Company’s shareholders at such meeting.

(u) “Employee” means any person employed by the Company or an Affiliate. However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of the Plan.

## 1. General; Purpose.

The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan.

(b) The Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related Corporations.

## 2. Administration.

(a) The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in Section 2(c).

(b) The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical).

(ii) To designate from time to time which Related Corporations of the Company will be eligible to participate in the Plan.

(iii) To construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make the Plan fully effective.

(iv) To settle all controversies regarding the Plan and Purchase Rights granted under the Plan.

(v) To suspend or terminate the Plan at any time as provided in Section 12.

(vi) To amend the Plan at any time as provided in Section 12.

(vii) Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote the best interests of the Company and its Related Corporations and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan.

(viii) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign nationals or employed outside the United States.

(c) The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan.

(d) All determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

B-1

## 3. Shares of Common Stock Subject to the Plan.

(a) Subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the maximum number of shares of Common Stock that may be issued under the Plan will not exceed 120,000 shares of Common Stock, plus the number of shares of Common Stock that are automatically added on January 1st of each year for a period of up to ten years, commencing on the first January 1 following the Effective Date and ending on (and including) January 1, 2026, in an amount equal to the lesser of (i) 1% of the total number of shares of Capital Stock outstanding on December 31st of the preceding calendar year, and (ii) 300,000 shares of Common Stock. Notwithstanding the foregoing, the Board may act prior to the first day of any calendar year to provide that there will be no January 1st increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence.

(b) If any Purchase Right granted under the Plan terminates without having been exercised in full, the shares of Common Stock not purchased under such Purchase Right will again become available for issuance under the Plan.

(c) The stock purchasable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market.

## 4. Grant of Purchase Rights; Offering.

(a) The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem appropriate, and will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8, inclusive.

(b) If a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise indicates in forms delivered to the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices) will be exercised.

(c) The Board will have the discretion to structure an Offering so that if the Fair Market Value of a share of Common Stock on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for that Offering, then (i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase Period.

## 5. Eligibility.

(a) Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to Employees of a Related Corporation. Except as provided in Section 5(b), an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee has been in the employ of the Company or the Related Corporation, as the case may be, for such continuous period preceding such Offering Date as the Board may require, but in no event will the required period of continuous employment be equal to or greater than two years. In addition, the Board may provide that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such Employee’s customary employment with the Company or the Related Corporation is more than 20 hours per week and more than five months per calendar year or such other criteria as the Board may determine consistent with Section 423 of the Code.

B-2

(b) The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that Offering, as described herein, except that:

(i) the date on which such Purchase Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right;

(ii) the period of the Offering with respect to such Purchase Right will begin on its Offering Date and end coincident with the end of such Offering; and

(iii) the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Purchase Right under that Offering.

(c) No Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase Rights are granted, such Employee owns stock possessing five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase Rights and options will be treated as stock owned by such Employee.

(d) As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase stock of the Company or any Related Corporation to accrue at a rate which exceeds $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time.

(e) Officers of the Company and any designated Related Corporation, if they are otherwise Eligible Employees, will be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code will not be eligible to participate.

## 6. Purchase Rights; Purchase Price.

(a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock purchasable either with a percentage or with a maximum dollar amount, as designated by the Board, but in either case not exceeding 15% of such Employee’s earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering.

(b) The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised and shares of Common Stock will be purchased in accordance with such Offering.

(c) In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants pursuant to such Offering and/or (iii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of shares of Common Stock issuable upon exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of the shares of Common Stock available will be made in as nearly a uniform manner as will be practicable and equitable.

B-3

(d) The purchase price of shares of Common Stock acquired pursuant to Purchase Rights will be not less than the lesser of:

(i) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or

(ii) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the applicable Purchase Date.

## 7. Participation; Withdrawal; Termination.

(a) An Eligible Employee may elect to authorize payroll deductions as the means of making Contributions by completing and delivering to the Company, within the time specified in the Offering, an enrollment form provided by the Company. The enrollment form will specify the amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the Company except where applicable law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first payroll occurring on or after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If specifically provided in the Offering, in addition to making Contributions by payroll deductions, a Participant may make Contributions through the payment by cash or check prior to a Purchase Date.

(b) During an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute to such Participant all of his or her accumulated but unused Contributions and such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings.

(c) Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation period required by law) or (ii) is otherwise no longer eligible to participate. The Company will distribute to such individual all of his or her accumulated but unused Contributions.

(d) During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10.

(e) Unless otherwise specified in the Offering, the Company will have no obligation to pay interest on Contributions.

## 8. Exercise of Purchase Rights.

(a) On each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of shares of Common Stock, up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will be issued unless specifically provided for in the Offering.

(b) If any amount of accumulated Contributions remains in a Participant’s account after the purchase of shares of Common Stock and such remaining amount is less than the amount required to purchase one share of Common Stock on the final Purchase Date of an Offering, then such remaining amount will be held in such Participant’s account for the purchase of shares of Common Stock under the next Offering under the Plan, unless such Participant withdraws from or is not eligible to participate in such Offering, in which case such amount will be distributed to such Participant after the final Purchase Date, without interest. If the amount of Contributions remaining in a Participant’s account after the purchase of shares of Common Stock is at least

B-4

equal to the amount required to purchase one whole share of Common Stock on the final Purchase Date of an Offering, then such remaining amount will not roll over to the next Offering and will instead be distributed in full to such Participant after the final Purchase Date of such Offering without interest.

(c) No Purchase Rights may be exercised to any extent unless the shares of Common Stock to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable federal, state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the Purchase Date will be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than six months from the Offering Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are not registered and the Plan is not in material compliance with all applicable laws, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed to the Participants without interest.

## 9. Covenants of the Company.

The Company will seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock thereunder. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale of Common Stock under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Common Stock upon exercise of such Purchase Rights.

## 10. Designation of Beneficiary.

(a) The Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any shares of Common Stock and/or Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company.

(b) If a Participant dies, and in the absence of a valid beneficiary designation, the Company will deliver any shares of Common Stock and/or Contributions to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares of Common Stock and/or Contributions to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

## 11. Adjustments upon Changes in Common Stock; Corporate Transactions.

(a) In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase automatically each year pursuant to Section 3(a), (iii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive.

(b) In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration paid to the shareholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common Stock within ten business days prior to the Corporate Transaction under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase.

B-5

## 12. Amendment, Termination or Suspension of the Plan.

(a) The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, shareholder approval will be required for any amendment of the Plan for which shareholder approval is required by applicable law or listing requirements, including any amendment that either (i) materially increases the number of shares of Common Stock available for issuance under the Plan, (ii) materially expands the class of individuals eligible to become Participants and receive Purchase Rights, (iii) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which shares of Common Stock may be purchased under the Plan, (iv) materially extends the term of the Plan, or (v) expands the types of awards available for issuance under the Plan, but in each of (i) through (v) above only to the extent shareholder approval is required by applicable law or listing requirements.

## 13. Effective Date of Plan.

The Plan will become effective immediately prior to and contingent upon the Effective Date.

3.1 AmpliPhi Washington Common Stock. Upon the Effective Time, each share of AmpliPhi Washington Common Stock issued and outstanding immediately prior thereto shall, by virtue of the Merger and without any action by the Constituent Corporations, the holder of such shares or any other person, be converted into and exchanged for one (1) legally issued, fully paid and nonassessable share of AmpliPhi Delaware Common Stock.

3.2 AmpliPhi Delaware Common Stock. Upon the Effective Time, each share of AmpliPhi Delaware Common Stock issued and outstanding immediately prior thereto shall, by virtue of the Merger and without any action by AmpliPhi Delaware, or the holder of such shares or any other person, be cancelled and returned to the status of authorized and unissued shares of AmpliPhi Delaware Common Stock, without any consideration being delivered in respect thereof.

AmpliPhi Delaware Common Stock on the same terms and conditions. A number of shares of AmpliPhi Delaware Common Stock shall upon the Effective Time be reserved for issuance upon the exercise or conversion of Rights equal to the number of shares of AmpliPhi Washington Common Stock so reserved immediately prior to the Effective Time.

3.4 Exchange of Certificates. After the Effective Time, each holder of an outstanding certificate representing shares of AmpliPhi Washington Common Stock may, at such shareholder’s option, surrender the same for cancellation to an exchange agent designated by the Surviving Corporation (the “Exchange Agent”), and each such holder shall be entitled to receive in exchange therefor a certificate or certificates representing the number of shares of AmpliPhi Delaware Common Stock into which the shares formerly represented by the surrendered certificate were converted as herein provided. Until so surrendered, each certificate representing shares of AmpliPhi Washington Common Stock outstanding immediately prior to the Effective Time shall be deemed for all purposes, from and after the Effective Time, to represent the number of shares of AmpliPhi Delaware Common Stock into which such shares of AmpliPhi Washington Common Stock were converted in the Merger.

The registered owner on the books and records of the Surviving Corporation or the Exchange Agent of any shares of stock represented by such certificate shall, until such certificate shall have been surrendered for transfer or conversion or otherwise accounted for to the Surviving Corporation or the Exchange Agent, have and be entitled to exercise any voting and other rights with respect to and to receive dividends and other distributions upon the shares of AmpliPhi Delaware Common Stock represented by such certificate as provided above.

Each certificate representing shares of AmpliPhi Delaware Common Stock so issued in the Merger shall bear the same legends, if any, with respect to the restrictions on transferability as the certificate of AmpliPhi Washington Common Stock so converted and given in exchange therefor (and such legends shall continue to be reflected for any such shares held in book entry), unless otherwise determined by the Board of Directors of the Surviving Corporation in compliance with applicable laws.

If any certificate for shares of the Surviving Corporation’s stock is to be issued in a name other than that in which the certificate surrendered in exchange therefor is registered, it shall be a condition of issuance thereof that the certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer, that such transfer otherwise be proper and comply with applicable securities laws and that the person requesting such transfer pay to the Exchange Agent any transfer or other taxes payable by reason of the issuance of such new certificate in a name other than that of the registered holder of the certificate surrendered or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not payable.

3.5 Shareholder Agreements. In the event any outstanding shares of capital stock of AmpliPhi Washington are subject to any agreements between AmpliPhi Washington and one or more shareholders, or among shareholders, such agreements shall remain in full force and effect following the Effective Time, substituting the applicable shares of capital stock of AmpliPhi Delaware, including without limitation any outstanding restricted stock purchase agreements or stock option agreements issued under the Plans.

Each option, restricted stock unit, stock appreciation right or right to purchase or receive, or security convertible into, AmpliPhi Washington Common Stock that is outstanding and unexercised (as applicable) immediately prior to the Effective Time shall become an option, restricted stock unit, stock appreciation right or right to purchase or receive, or security convertible into, AmpliPhi Delaware Common Stock, on the basis of one (1) share of AmpliPhi Delaware Common Stock for each share

D-3

of AmpliPhi Washington Common Stock issuable pursuant to such option, restricted stock unit, stock appreciation right or right to purchase or receive, or convertible security, on all of the same terms and conditions and at an exercise, conversion or purchase price (as applicable) per share equal to the exercise, conversion or purchase price (as applicable) per share applicable to any such option, restricted stock unit, stock appreciation right or right to purchase or receive, or security convertible into, AmpliPhi Washington Common Stock as in effect immediately prior to the Effective Time.

(b) Upon the Effective Time, a number of shares of AmpliPhi Delaware Common Stock shall be reserved for issuance under the Plans equal to the number of shares of AmpliPhi Washington Common Stock so reserved immediately prior to the Effective Time.

FOURTH: This Certificate of Incorporation has been duly approved and adopted by the stockholders of the Corporation in accordance with the applicable provisions of Sections 211, 242 and 245 of the DGCL.

FIFTH: The text of this Certificate of Incorporation, as heretofore amended or supplemented, is hereby amended and restated in its entirety to read as follows:

# I.

The name of this corporation is AmpliPhi Biosciences Corporation.

# II.

The address of the registered office of the corporation in the State of Delaware is 160 Greentree Drive, Suite 101, City of Dover, County of Kent, 19904, and the name of the registered agent of the corporation in the State of Delaware at such address is the National Registered Agents, Inc.

# III.

The purpose of this corporation is to engage in any lawful act or activity for which a corporation may be organized under the DGCL.

# IV.

A. This corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares which the corporation is authorized to issue is one hundred sixty million (160,000,000) shares. One hundred fifty million (150,000,000) shares shall be Common Stock, each having a par value of one cent ($0.01). Ten million (10,000,000) shares shall be Preferred Stock, each having a par value of one cent ($0.01).

The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares of Common Stock then outstanding) by the affirmative vote of the holders of the stock of the corporation entitled to vote, voting together as a single class, irrespective of Section 242(b)(2) of the DGCL.

B. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors is hereby expressly authorized to provide for the issue of all of any of the remaining shares of the Preferred Stock in one or more series, and to fix the number of shares and to determine or alter for each such series, such voting powers, full or limited, or no voting powers, and such designation, preferences, and relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such shares and as may be permitted by the DGCL. The Board of Directors is also expressly

E-1

authorized to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be decreased in accordance with the foregoing sentence, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series. The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of the stock of the corporation entitled to vote thereon, without a separate vote of the holders of the Preferred Stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any certificate of designation filed with respect to any series of Preferred Stock.

C. Each outstanding share of Common Stock shall entitle the holder thereof to one vote on each matter properly submitted to the stockholders of the corporation for their vote; provided, however, that, except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any certificate of designation filed with respect to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon by law or pursuant to this Certificate of Incorporation (including any certificate of designation filed with respect to any series of Preferred Stock).

# V.

For the management of the business and for the conduct of the affairs of the corporation, and in further definition, limitation and regulation of the powers of the corporation, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that:

A. The management of the business and the conduct of the affairs of the corporation shall be vested in its Board of Directors. The number of directors which shall constitute the Board of Directors shall be fixed exclusively by resolutions adopted by a majority of the authorized number of directors constituting the Board of Directors.

B. Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively. The Board of Directors is authorized to assign members of the Board of Directors already in office to such classes at the time the classification becomes effective. At the first annual meeting of stockholders following the initial classification of the Board of Directors, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the second annual meeting of stockholders following such initial classification, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At the third annual meeting of stockholders following such initial classification, the term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting.

Notwithstanding the foregoing provisions of this section, each director shall serve until his successor is duly elected and qualified or until his earlier death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

C. Subject to the rights of any series of Preferred Stock to elect additional directors under specified circumstances, neither the Board of Directors nor any individual director may be removed without cause.

D. Subject to any limitations imposed by applicable law, any individual director or directors may be removed with cause by the affirmative vote of the holders of sixty-six and two-thirds percent (66 2/3%) of the voting power of all then-outstanding shares of capital stock of the corporation entitled to vote generally at an election of directors.

E. Subject to any limitations imposed by applicable law and subject to the rights of the holders of any series of Preferred Stock, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in

E-2

the number of directors, shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by the stockholders and except as otherwise provided by applicable law, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the Board of Directors, and not by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director’s successor shall have been elected and qualified.

F. The Board of Directors is expressly empowered to adopt, amend or repeal the Bylaws of the corporation. Any adoption, amendment or repeal of the Bylaws of the corporation by the Board of Directors shall require the approval of a majority of the authorized number of directors. The stockholders shall also have power to adopt, amend or repeal the Bylaws of the corporation; provided, however, that, in addition to any vote of the holders of any class or series of stock of the corporation required by law or by this Certificate of Incorporation, such action by stockholders shall require the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of the voting power of all of the then-outstanding shares of the capital stock of the corporation entitled to vote generally in the election of directors, voting together as a single class.

G. The directors of the corporation need not be elected by written ballot unless the Bylaws so provide.

H. No action shall be taken by the stockholders of the corporation except at an annual or special meeting of stockholders called in accordance with the Bylaws.

I. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the corporation shall be given in the manner provided in the Bylaws of the corporation.

# VI.

A. The liability of the directors for monetary damages shall be eliminated to the fullest extent under applicable law.

B. To the fullest extent permitted by applicable law, the corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of the corporation (and any other persons to which applicable law permits the corporation to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise in excess of the indemnification and advancement otherwise permitted by such applicable law. If applicable law is amended after approval by the stockholders of this Article VI to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director to the corporation shall be eliminated or limited to the fullest extent permitted by applicable law as so amended.

C. Any repeal or modification of this Article VI shall only be prospective and shall not affect the rights or protections or increase the liability of any director under this Article VI in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

# VII.

Unless the corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the corporation; (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the corporation to the corporation or the corporation’s stockholders; (3) any action asserting a claim against the corporation or any director or officer or other employee of the corporation arising pursuant to any provision of the DGCL, this Certificate of Incorporation or the Bylaws of the corporation; and (4) any action asserting a claim against the corporation or any director or officer or other employee of the corporation governed by the internal affairs doctrine.

E-3

# VIII.

A. The corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, except as provided in paragraph B. of this Article VIII, and all rights conferred upon the stockholders herein are granted subject to this reservation.

B. Notwithstanding any other provisions of this Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the corporation required by law or by this Certificate of Incorporation or any certificate of designation filed with respect to a series of Preferred Stock, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66- 2/3%) of the voting power of all of the then-outstanding shares of capital stock of the corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend or repeal Articles V, VI, VII and VIII of this Certificate of Incorporation.

i. For nominations for the election to the Board of Directors to be properly brought before an annual meeting by a stockholder pursuant to clause (iii) of Section 5(a) of these Bylaws, the stockholder must deliver written notice to the Secretary at the principal executive offices of the corporation on a timely basis as set forth in Section 5(b)(iii) of these Bylaws and must update and supplement such written notice on a timely basis as set forth in Section 5(c) of these Bylaws.

For purposes of this Section 5, an “Expiring Class” shall mean a class of directors whose term shall expire at the next annual meeting of stockholders.

(f) A person shall not be eligible for election or re-election as a director unless the person is nominated either in accordance with clause (ii) of Section 5(a) of these Bylaws, or in accordance with clause (iii) of Section 5(a) of these Bylaws. Except as otherwise required by law, the chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made, or proposed, as the case may be, in accordance with the procedures set forth in these Bylaws and, if any proposed nomination or business is not in compliance with these Bylaws, or the Proponent does not act in accordance with the representations in Sections 5(b)(iv)(D) and 5(b)(iv)(E) of these Bylaws, to declare that such proposal or nomination shall not be presented for stockholder action at the meeting and shall be disregarded, notwithstanding that proxies in respect of such nominations or such business may have been solicited or received.

(g) Notwithstanding the foregoing provisions of this Section 5, in order to include information with respect to a stockholder proposal in the proxy statement and form of proxy for a stockholders’ meeting, a stockholder must also comply with all applicable requirements of the 1934 Act and the rules and regulations thereunder. Nothing in these Bylaws shall be deemed to affect any rights of stockholders to request inclusion of proposals in the corporation’s proxy statement pursuant to Rule 14a-8 under the 1934 Act; provided, however, that any references in these Bylaws to the 1934 Act or the rules and regulations

F-4

thereunder are not intended to and shall not limit the requirements applicable to proposals and/or nominations to be considered pursuant to Section 5(a)(iii) of these Bylaws.

(h) For purposes of Sections 5 and 6 of these Bylaws,

i. “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the 1934 Act; and

(b) The Board of Directors shall determine the time and place, if any, of such special meeting. Upon determination of the time and place, if any, of the meeting, the Secretary shall cause a notice of meeting to be given to the stockholders entitled to vote, in accordance with the provisions of Section 7 of these Bylaws. No business may be transacted at such special meeting otherwise than specified in the notice of meeting.

In the event the corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board of Directors, any such stockholder of record may nominate a person or persons (as the case may be), for election to such position(s) as specified in the corporation’s notice of meeting, if written notice setting forth the information required by Section 5(b)(i) of these Bylaws shall be received by the Secretary at the principal executive offices of the corporation not later than the close of business on the later of the 90th day prior to such meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. The stockholder shall also update and supplement such information as required under Section 5(c) of these Bylaws. In no event shall an adjournment or a postponement of a special meeting for which notice has been given, or the public announcement thereof has been made, commence a new time period for the giving of a stockholder’s notice as described above.

(d) Notwithstanding the foregoing provisions of this Section 6, a stockholder must also comply with all applicable requirements of the 1934 Act and the rules and regulations thereunder with respect to matters set forth in this Section 6. Nothing in these Bylaws shall be deemed to affect any rights of stockholders to request inclusion of proposals in the corporation’s proxy statement pursuant to Rule 14a-8 under the 1934 Act; provided, however, that any references in these Bylaws to the 1934 Act or the rules and regulations thereunder are not intended to and shall not limit the requirements applicable to nominations for the election to the Board of Directors to be considered pursuant to Section 6(c) of these Bylaws.

Section 7. Notice of Meetings. Except as otherwise provided by law, notice, given in writing or by electronic transmission, of each meeting of stockholders shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting, such notice to specify the place, if any, date and hour, in the case of special meetings, the purpose or purposes of the meeting, and the

F-5

means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at any such meeting. If mailed, notice is deemed given when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of the corporation. If sent via electronic transmission, notice is deemed given as of the sending time recorded at the time of transmission. Notice of the time, place, if any, and purpose of any meeting of stockholders may be waived in writing, signed by the person entitled to notice thereof, or by electronic transmission by such person, either before or after such meeting, and will be waived by any stockholder by his attendance thereat in person, by remote communication, if applicable, or by proxy, except when the stockholder attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Any stockholder so waiving notice of such meeting shall be bound by the proceedings of any such meeting in all respects as if due notice thereof had been given.

Section 8. Quorum. At all meetings of stockholders, except where otherwise provided by statute or by the corporation’s Certificate of Incorporation (“Certificate of Incorporation”), or by these Bylaws, the presence, in person, by remote communication, if applicable, or by proxy duly authorized, of the holders of a majority of the outstanding shares of stock entitled to vote shall constitute a quorum for the transaction of business. In the absence of a quorum, any meeting of stockholders may be adjourned, from time to time, either by the chairman of the meeting or by vote of the holders of a majority of the shares represented thereat, but no other business shall be transacted at such meeting. The stockholders present at a duly called or convened meeting, at which a quorum is present, may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. Except as otherwise provided by statute or by applicable stock exchange rules, or by the Certificate of Incorporation or these Bylaws, in all matters other than the election of directors, the affirmative vote of the majority of shares present in person, by remote communication, if applicable, or represented by proxy at the meeting and entitled to vote generally on the subject matter shall be the act of the stockholders. Except as otherwise provided by statute, the Certificate of Incorporation or these Bylaws, directors shall be elected by a plurality of the votes of the shares present in person, by remote communication, if applicable, or represented by proxy at the meeting and entitled to vote generally on the election of directors. Where a separate vote by a class or classes or series is required, except where otherwise provided by the statute or by the Certificate of Incorporation or these Bylaws, a majority of the outstanding shares of such class or classes or series, present in person, by remote communication, if applicable, or represented by proxy duly authorized, shall constitute a quorum entitled to take action with respect to that vote on that matter. Except where otherwise provided by statute or by the Certificate of Incorporation or these Bylaws, the affirmative vote of the majority (plurality, in the case of the election of directors) of shares of such class or classes or series present in person, by remote communication, if applicable, or represented by proxy at the meeting shall be the act of such class or classes or series.

Section 9. Adjournment and Notice of Adjourned Meetings. Any meeting of stockholders, whether annual or special, may be adjourned from time to time either by the chairman of the meeting or by the vote of a majority of the shares present in person, by remote communication, if applicable, or represented by proxy at the meeting. When a meeting is adjourned to another time or place, if any, notice need not be given of the adjourned meeting if the time and place, if any, thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 10. Voting Rights. For the purpose of determining those stockholders entitled to vote at any meeting of the stockholders, except as otherwise provided by law, only persons in whose names shares stand on the stock records of the corporation on the record date, as provided in Section 12 of these Bylaws, shall be entitled to vote at any meeting of stockholders. Every person entitled to vote shall have the right to do so either in person, by remote communication, if applicable, or by an agent or agents authorized by a proxy granted in accordance with Delaware law. An agent so appointed need not be a stockholder. No proxy shall be voted after three years from its date of creation unless the proxy provides for a longer period.

Section 11. Joint Owners of Stock. If shares or other securities having voting power stand of record in the names of two or more persons, whether fiduciaries, members of a partnership, joint tenants, tenants in common, tenants by the entirety, or otherwise, or if two or more persons have the same fiduciary relationship respecting the same shares, unless the Secretary is given written notice to the contrary and is furnished with a copy of the instrument or order appointing them or creating the relationship wherein it is so provided, their acts with respect to voting shall have the following effect: (a) if only one votes, his act binds all; (b) if more than one votes, the act of the majority so voting binds all; or (c) if more than one votes, but the vote is evenly split on any particular matter, each faction may vote the securities in question proportionally, or may apply to the Delaware Court of Chancery for relief as provided in the DGCL, Section 217(b). If the instrument filed with the Secretary shows that any such tenancy is held in unequal interests, a majority or even-split for the purpose of clause (c) of this Section 11 shall be a majority or even-split in interest.

Section 12. List of Stockholders. The Secretary shall prepare and make, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at said meeting, arranged in alphabetical order, showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the corporation. In the event that the corporation determines to make the list available on an electronic network, the corporation may take reasonable steps to ensure that such information is available only to stockholders of the corporation. The list shall be open to examination of any stockholder during the time of the meeting as provided by law.

Section 13. Action Without Meeting. No action shall be taken by the stockholders except at an annual or special meeting of stockholders called in accordance with these Bylaws, and no action shall be taken by the stockholders by written consent or electronic transmission.

Section 14. Organization.

(a) At every meeting of stockholders, the Chairman of the Board of Directors, or, if a Chairman has not been appointed or is absent, the President, or, if the President is absent, a chairman of the meeting chosen by a majority in interest of the stockholders entitled to vote, present in person or by proxy, shall act as chairman. The Secretary, or, in his or her absence, an Assistant Secretary directed to do so by the President, shall act as secretary of the meeting.

(b) The Board of Directors of the corporation shall be entitled to make such rules or regulations for the conduct of meetings of stockholders as it shall deem necessary, appropriate or convenient. Subject to such rules and regulations of the Board of Directors, if any, the chairman of the meeting shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are necessary, appropriate or convenient for the proper conduct of the meeting, including, without limitation, establishing an agenda or order of business for the meeting, rules and procedures for maintaining order at the meeting and the safety of those present, limitations on participation in such meeting to stockholders of record of the corporation and their duly authorized and constituted proxies and such other persons as the chairman shall permit, restrictions on entry to the meeting after the time fixed for the commencement thereof, limitations on the time allotted to questions or comments by participants and regulation of the opening and closing of the polls for balloting on matters which are to be voted on by ballot. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at the meeting shall be announced at the meeting. Unless and to the extent determined by the Board of Directors or the chairman of the meeting, meetings of stockholders shall not be required to be held in accordance with rules of parliamentary procedure.

# ARTICLE IV
DIRECTORS

Section 15. Number and Term of Office. The authorized number of directors of the corporation shall be fixed in accordance with the Certificate of Incorporation. Directors need not be stockholders unless so required by the Certificate of Incorporation. If for any cause, the directors shall not have been elected at an annual meeting, they may be elected as soon thereafter as convenient at a special meeting of the stockholders called for that purpose in the manner provided in these Bylaws.

Section 16. Powers. The business and affairs of the corporation shall be managed by or under the direction of the Board of Directors, except as may be otherwise provided by statute or by the Certificate of Incorporation.

Section 17. Classes of Directors.

Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively. Initially, directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board of Directors. At the first annual meeting of stockholders following the adoption of these Bylaws, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the second annual meeting of stockholders following the adoption of these Bylaws, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At the third annual meeting of stockholders following the adoption of these Bylaws, the term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting.

Notwithstanding the foregoing provisions of this Section 17, each director shall serve until his successor is duly elected and qualified or until his earlier death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

Section 18. Vacancies.

(a) Unless otherwise provided in the Certificate of Incorporation, and subject to the rights of the holders of any series of Preferred Stock, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by stockholders, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the Board of Directors, or by a sole remaining director, and not by the stockholders, provided, however, that whenever the holders of any class or classes of stock or series thereof are entitled to elect one or more directors by the provisions of the Certificate of Incorporation, vacancies and newly created directorships of such class or classes or series shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by stockholders, be filled by a majority of the directors elected by such class or classes or series thereof then in office, or by a sole remaining director so elected, and not by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director’s successor shall have been elected and qualified. A vacancy in the Board of Directors shall be deemed to exist under this Bylaw in the case of the death, removal or resignation of any director.

Section 19. Resignation. Any director may resign at any time by delivering his or her notice in writing or by electronic transmission to the Secretary, such resignation to specify whether it will be effective at a particular time. If no such specification is made, it shall be deemed effective at the time of delivery to the Secretary. When one or more directors shall resign from the Board of Directors, effective at a future date, a majority of the directors then in office, including those who have so resigned, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become

Section 21. Duties of Chairman of the Board of Directors. The Chairman of the Board of Directors, when present, shall preside at all meetings of the stockholders and the Board of Directors.

Notice of any meeting may be waived in writing, or by electronic transmission, at any time before or after the meeting and will be waived by any director by attendance thereat, except when the director attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

(e) Waiver of Notice. The transaction of all business at any meeting of the Board of Directors, or any committee thereof, however called or noticed, or wherever held, shall be as valid as though it had been transacted at a meeting duly held after regular call and notice, if a quorum be present and if, either before or after the meeting, each of the directors not present who did not receive notice shall sign a written waiver of notice or shall waive notice by electronic transmission. All such waivers shall be filed with the corporate records or made a part of the minutes of the meeting.

Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

Section 25. Fees and Compensation. Directors shall be entitled to such compensation for their services as may be approved by the Board of Directors, including, if so approved, by resolution of the Board of Directors, a fixed sum and expenses of attendance, if any, for attendance at each regular or special meeting of the Board of Directors and at any meeting of a committee of the Board of Directors. Nothing herein contained shall be construed to preclude any director from serving the corporation in any other capacity as an officer, agent, employee, or otherwise and receiving compensation therefor.

Section 26. Committees.

(a) Executive Committee. The Board of Directors may appoint an Executive Committee to consist of one or more members of the Board of Directors.

# ARTICLE XI
INDEMNIFICATION

Section 45. Indemnification of Directors, Officers, Employees and Other Agents.

(a) Directors and Officers. The corporation shall indemnify its directors and officers to the extent not prohibited by the DGCL or any other applicable law; provided, however, that the corporation may modify the extent of such indemnification by individual contracts with its directors and officers; and, provided, further, that the corporation shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by the Board of Directors of the corporation, (iii) such indemnification is provided by the corporation, in its sole discretion, pursuant to the powers vested in the corporation under the DGCL or any other applicable law or (iv) such indemnification is required to be made under subsection (d).

(b) Employees and Other Agents. The corporation shall have power to indemnify its employees and other agents as set forth in the DGCL or any other applicable law. The Board of Directors shall have the power to delegate the determination of whether to indemnify any such employee or other agent to such officers or other persons as the Board of Directors so determines.

(c) Expenses. The corporation shall advance to any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director or officer, of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, prior to the final disposition of the proceeding, promptly following request therefor, all expenses incurred by any director or officer in connection with such proceeding provided, however, that if the DGCL requires, an advancement of expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the corporation of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnitee is not entitled to be indemnified for such expenses under this Section 45 or otherwise.

Notwithstanding the foregoing, unless otherwise determined pursuant to paragraph (e) of this Section 45, no advance shall be made by the corporation to an officer of the corporation (except by reason of the fact that such officer is or was a director of the corporation in which event this paragraph shall not apply) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, if a determination is reasonably and promptly made (i) by a majority vote of directors who were not parties to the proceeding, even if not a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or such directors so direct, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation.

(d) Enforcement. Without the necessity of entering into an express contract, all rights to indemnification and advances to directors and officers under this Section 45 shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the corporation and the director or officer. Any right to indemnification or advances granted by this Section 45 to a director or officer shall be enforceable by or on behalf of the person holding such right in any court of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim is made within 90 days of request therefor. To the extent permitted by law, the claimant in such enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting the claim. In connection with any claim for indemnification, the corporation shall be entitled to raise as a defense to any such action that the claimant

F-16

has not met the standards of conduct that make it permissible under the DGCL or any other applicable law for the corporation to indemnify the claimant for the amount claimed. In connection with any claim by an officer of the corporation (except in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such officer is or was a director of the corporation) for advances, the corporation shall be entitled to raise a defense as to any such action clear and convincing evidence that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation, or with respect to any criminal action or proceeding that such person acted without reasonable cause to believe that his conduct was lawful. Neither the failure of the corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because the officer or director has met the applicable standard of conduct set forth in the DGCL or any other applicable law, nor an actual determination by the corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of conduct. In any suit brought by a director or officer to enforce a right to indemnification or to an advancement of expenses hereunder, the burden of proving that the director or officer is not entitled to be indemnified, or to such advancement of expenses, under this Section 45 or otherwise shall be on the corporation.

(e) Non-Exclusivity of Rights. The rights conferred on any person by this Bylaw shall not be exclusive of any other right which such person may have or hereafter acquire under any applicable statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding office. The corporation is specifically authorized to enter into individual contracts with any or all of its directors, officers, employees or agents respecting indemnification and advances, to the fullest extent not prohibited by the DGCL, or by any other applicable law.

(f) Survival of Rights. The rights conferred on any person by this Bylaw shall continue as to a person who has ceased to be a director or officer, or, if applicable, employee or other agent, and shall inure to the benefit of the heirs, executors and administrators of such a person.

(g) Insurance. To the fullest extent permitted by the DGCL or any other applicable law, the corporation, upon approval by the Board of Directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to this Section 45.

(h) Amendments. Any repeal or modification of this Section 45 shall only be prospective and shall not affect the rights under this Bylaw in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any proceeding against any agent of the corporation.

(i) Saving Clause. If this Bylaw or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director and officer to the full extent not prohibited by any applicable portion of this Section 45 that shall not have been invalidated, or by any other applicable law. If this Section 45 shall be invalid due to the application of the indemnification provisions of another jurisdiction, then the corporation shall indemnify each director and officer to the full extent under any other applicable law.

(j) Certain Definitions. For the purposes of this Bylaw, the following definitions shall apply:

i. The term “proceeding” shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of testimony in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

ii. The term “expenses” shall be broadly construed and shall include, without limitation, court costs, attorneys’ fees, witness fees, fines, amounts paid in settlement or judgment and any other costs and expenses of any nature or kind incurred in connection with any proceeding.

The term the “corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section 45 with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

iv. References to a “director,” “officer,” “employee,” or “agent” of the corporation shall include, without limitation, situations where such person is serving at the request of the corporation as, respectively, a director, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust or other enterprise.

v. References to “other enterprise” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this Section 45.

(b) Notice to Directors.

(d) Methods of Notice. It shall not be necessary that the same method of giving notice be employed in respect of all recipients of notice, but one permissible method may be employed in respect of any one or more, and any other permissible method or methods may be employed in respect of any other or others.

(e) Notice to Person with whom Communication is Unlawful. Whenever notice is required to be given, under any provision of law or of the Certificate of Incorporation or Bylaws of the corporation, to any person with whom communication is unlawful, the giving of such notice to such person shall not be

F-18

required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the corporation is such as to require the filing of a certificate under any provision of the DGCL, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.

(f) Notice to Stockholders Sharing an Address. Except as otherwise prohibited under the DGCL, any notice given under the provisions of the DGCL, the Certificate of Incorporation or the Bylaws shall be effective if given by a single written notice to stockholders who share an address if consented to by the stockholders at that address to whom such notice is given. Such consent shall have been deemed to have been given if such stockholder fails to object in writing to the corporation within 60 days of having been given notice by the corporation of its intention to send the single notice. Any consent shall be revocable by the stockholder by written notice to the corporation.

The stockholders also shall have power to adopt, amend or repeal the Bylaws of the corporation; provided, however, that, in addition to any vote of the holders of any class or series of stock of the corporation required by law or by the Certificate of Incorporation, such action by stockholders shall require the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of the capital stock of the corporation entitled to vote generally in the election of directors, voting together as a single class.

On May 31, 2016, AmpliPhi Biosciences Corporation (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional purchasers (the “Purchasers”). Pursuant to the terms of the Purchase Agreement, the Company has agreed to sell an aggregate of 2,127,660 shares of common stock together with warrants to purchase up to an aggregate of 1,063,830 shares of common stock. Each share of common stock is being sold together with a warrant to purchase 0.50 of a share of common stock at a combined purchase price of $2.35. The net proceeds to the Company from the offering are expected to be approximately $4.5 million, after deducting placement agent fees and estimated offering expenses payable by the Company, but excluding the proceeds, if any, from the exercise of the warrants issued in the offering. The offering is expected to close on or about June 3, 2016, subject to customary closing conditions.

The warrants will have an exercise price of $2.25 per share, will be immediately exercisable and will expire five years following the date of issuance.

Pursuant to an agreement dated May 31, 2016 (the “Placement Agency Agreement”), the Company engaged Roth Capital Partners, LLC and Griffin Securities, Inc. (the “Co-Placement Agents”) to act as co-placement agents in connection with the issuance and sale of the shares and warrants. The Company has agreed to pay the Co-Placement Agents 7.0% of the aggregate gross proceeds from the offering, excluding the proceeds, if any, from the exercise of the warrants. The Company also agreed to reimburse the Co-Placement Agents for their out of pocket and legal expenses in connection with the offering in an amount not to exceed $75,000.

The offering is being made pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-210974) previously filed with the Securities and Exchange Commission (“SEC”) and a prospectus supplement thereunder. A copy of the opinion of Cooley LLP relating to the legality of the issuance and sale of the securities in the offering is attached as Exhibit 5.1 hereto. On May 31, 2016, the Company also issued a press release announcing the pricing of the offering. A copy of the press release is attached as Exhibit 99.1 hereto.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), termination provisions, and other obligations and rights of the parties. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

The foregoing descriptions of the Placement Agency Agreement, Purchase Agreement and the warrants are not complete and are qualified in their entireties by reference to the full text of the Placement Agency Agreement, the form of Purchase Agreement and form of warrant, copies of which are attached to this report as Exhibit 99.2, Exhibit 99.3 and Exhibit 4.1, respectively.

Item 3.02 Unregistered Sales of Equity Securities.

As previously disclosed, on April 8, 2016 the Company entered into a Common Stock Issuance Agreement (the “CSIA”) with certain former holders of the Company’s Series B convertible preferred stock (the “Holders”). Pursuant to Section 3 of the CSIA, in the event the Company conducts one or more bona fide equity financings in which it sells shares of its common stock at a price of less than $4.05 per share, the Company will, subject to the provisions of Section 3 of the CSIA and to the extent permitted by NYSE MKT rules, issue to the Holders, for no additional consideration, a number of shares of common stock based on a specified formula. In connection with the offering described above under Item 1.01 and pursuant to the terms of the CSIA, the Company will be required to issue to the Holders within 15 business days following the closing of the offering up to an aggregate of 750,210 shares of common stock as a result of the price per share in the offering being less than $4.05 per share.

The maximum number of shares of common stock the Company is currently permitted to issue to the Holders pursuant to the Company’s obligations under Section 3 of the CSIA without shareholder approval is 323,235 shares. The Company is seeking, pursuant to Proposal 5 set forth in the Company’s Definitive Proxy Statement on Schedule 14A filed with the SEC on May 20, 2016, shareholder approval at its 2016 Annual Meeting of Shareholders (the “Annual Meeting”) of the issuance of up to an aggregate of 1,037,053 shares of common stock as and to the extent required pursuant to the terms of the CSIA. In the event that such Proposal 5 is not approved by the Company’s shareholders at the Annual Meeting, then the Company will be obligated to pay to the Holders $1.70 (representing the difference between $4.05 and the price per share in the offering of $2.35) for each of the remaining 426,975 shares that the Holders would otherwise have been entitled to receive pursuant to the CSIA in connection with the closing of the offering described above under Item 1.01.

None of the Holders are Purchasers in the offering.

The shares of common stock to be issued to the Holders pursuant to the CSIA will be issued in a private placement transaction exempt from registration pursuant to Section 4(a)(2) of the Securities Act. The Holders have represented to the Company that the shares will be acquired for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends will be affixed to the shares. Each of the Holders has represented to being an “accredited investor” under Rule 506 of Regulation D of the Securities Act.

COMMON STOCK PURCHASE WARRANT

AMPLIPHI BIOSCIENCES CORPORATION

Warrant Shares: _______ | Initial Exercise Date: June ____, 2016

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, _____________ or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise Date”) and on or prior to the close of business on the five year anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from Ampliphi Biosciences Corporation, a Washington corporation (the “Company”), up to ______ shares (as subject to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

Section 1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated May 31, 2016, among the Company and the purchasers signatory thereto.

Section 2. Exercise.

a) Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile copy (or e-mail attachment) of the Notice of Exercise in the form annexed hereto and , within one (1) Trading Day of the date said Notice of Exercise is delivered to the Company, payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

| 1 |

b) Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $2.25, subject to adjustment hereunder (the “Exercise Price”).

c) Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

| (A) = | the last VWAP immediately preceding the time of delivery of the Notice of Exercise giving rise to the applicable “cashless exercise”, as set forth in the applicable Notice of Exercise (to clarify, the “last VWAP” will be the last VWAP as calculated over an entire Trading Day such that, in the event that this Warrant is exercised at a time that the Trading Market is open, the prior Trading Day’s VWAP shall be used in this calculation);

| (B) = | the Exercise Price of this Warrant, as adjusted hereunder; and

| (X) = | the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 2(c).

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

| d) | Mechanics of Exercise.

i. Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is one (1) Trading Day after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares; provided payment of the aggregate Exercise Price (other than in the case of a Cashless Exercise) is received within three Trading Days of delivery of the Notice of Exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable.

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

| 3 |

iv. Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

| 4 |

vi. Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

vii. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

e) Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

| 5 |

Section 3. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

| 6 |

b) [RESERVED]

c) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

d) Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

| 7 |

e) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, concurrently with, the consummation of the Fundamental Transaction, the Company shall purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. The Company shall be required to give at least 20 days prior written notice of the occurrence of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

f) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

g) Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a) Transferability. Subject to applicable laws and compliance with the Purchas Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5. Miscellaneous.

a) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

| 10 |

b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

| 11 |

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement, including, without limitation, that all questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof.

f) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

i) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

| 12 |

j) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

l) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

m) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection with the offering by AmpliPhi Biosciences Corporation, a Washington corporation (the “Company”), of 2,127,660 shares (the “Shares”) of the Company’s common stock, par value $0.01 (the “Common Stock”), plus warrants (the “Warrants”) to purchase an additional 1,063,830 shares of the Company’s common stock (the “Warrant Shares”) pursuant to a Registration Statement on Form S-3 (Registration Statement No. 333-210974) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), the prospectus included within the Registration Statement (the “Base Prospectus”), and the prospectus supplement dated May 31, 2016, filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations of the Act (the “Prospectus Supplement”). The Base Prospectus and the Prospectus Supplement are collectively referred to as the “Prospectus.” The Shares, the Warrants and the Warrant Shares are to be sold by the Company as described in the Registration Statement and the Prospectus.

In connection with this opinion, we have examined and relied upon the Registration Statement, the Prospectus, the Company’s articles of incorporation and bylaws, as currently in effect, and the originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. We have assumed the genuineness and authenticity of all documents submitted to us as originals, and the conformity to originals of all documents submitted to us as copies thereof and the due execution and delivery of all documents where due execution and delivery are a prerequisite to the effectiveness thereof. With regard to our opinion regarding the Warrants and the Warrant Shares, (i) we have assumed that the exercise price of the Warrants at the time of exercise is equal to or greater than the par value of the Common Stock, and (ii) we express no opinion to the extent that, notwithstanding its current reservation of shares of Common Stock, future issuances of securities, including the Warrant Shares, of the Company and/or antidilution adjustments to outstanding securities, including the Warrants, of the Company cause the Warrants to be exercisable for more shares of Common Stock than the number that then remain authorized but unissued.

With regard to our opinion concerning the Warrants constituting valid and binding obligations of the Company:

AmpliPhi's product development programs target infections that are often resistant to existing antibiotic treatments. AmpliPhi is currently conducting a Phase 1 clinical trial of AB-SA01 for the treatment of Staphylococcus aureus (S. aureus) in chronic rhinosinusitis patients and another Phase 1 clinical trial to evaluate the safety of AB-SA01 when administered topically to the intact skin of healthy adults.

About Bacteriophage

Bacteriophage are naturally occurring viruses that are highly specific for the bacterial hosts they infect. They can rapidly kill their host, amplifying themselves in the process. Bacteriophage are unaffected by antibiotic resistance and are able to disrupt bacterial biofilms. Such biofilms are a major line of defense for bacteria, contributing to antibiotic resistance. Bacteriophage are able to penetrate biofilms and replicate locally to high levels, to produce strong local therapeutic effects.

Such registration statement, as amended (including any post effective amendments), has been declared effective by the Commission. Such registration statement, as amended (including post effective amendments thereto), the exhibits and any schedules thereto and the documents and information otherwise deemed to be a part thereof or included therein by the Securities Act or otherwise pursuant to the Rules and Regulations, is herein called the “Registration Statement.” If the Company has filed or files an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term Registration Statement shall include such Rule 462 Registration Statement.

| 13 |

(b) The Co-Placement Agents will indemnify and hold harmless the Company, its affiliates, directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Co-Placement Agents), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Marketing Materials, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by the Co-Placement Agents specifically for use in the preparation thereof, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with defending against any such loss, claim, damage, liability or action.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b), above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if (i) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (ii) a conflict or potential conflict exists (based on the reasonable advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, the indemnified party shall have the right to employ a single counsel to represent it in any claim in respect of which indemnity may be sought under subsection (a) or (b) of this Section 8, in which event the reasonable and documented fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the indemnified party as incurred.

| 14 |

The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is a party or could be named and indemnity was or would be sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all liability for claims that are the subject matter of such action, suit or proceeding and (b) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b), above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Co-Placement Agents, on the other hand, from the Offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Co-Placement Agents, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Co-Placement Agents, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the Offering (before deducting expenses) received by the Company, and the total placement agent fees received by the Co-Placement Agents, in each case as set forth on the cover page of the Final Prospectus, bear to the aggregate offering price of the Securities set forth on such cover. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Co-Placement Agents and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Co-Placement Agents agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim that is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d),the Co-Placement Agents shall not be required to contribute any amount in excess of the amount of the Co-Placement Agents’ placement agent fees actually received by the Co-Placement Agents from the Offering of the Securities. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

| 15 |

(e) The obligations of the Company under this Section 8 shall be in addition to any liability that the Company may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each person, if any, who controls the Co-Placement Agents within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and the obligations of the Co-Placement Agents under this Section 8 shall be in addition to any liability that the Co-Placement Agents may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to the Company, and its officers, directors and each person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act.

(f) For purposes of this Agreement, the Co-Placement Agents confirm, and the Company acknowledges, that there is no information concerning the Co-Placement Agents furnished in writing to the Company by the Co-Placement Agents specifically for preparation of or inclusion in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, other than the statements regarding the Co-Placement Agents set forth in the “Plan of Distribution” section of the Final Prospectus and Time of Sale Disclosure Package, only insofar as such statement relate to the amount of selling concession and related activities that may be undertaken by the Co-Placement Agents.

(aa) Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date.

The Company further represents to each Purchaser that the Company’s decision to enter into this Agreement and the other Transaction Documents has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

(ff) Acknowledgement Regarding Purchaser’s Trading Activity. Anything in this Agreement or elsewhere herein to the contrary notwithstanding (except for Sections 3.2(f) and 4.14 hereof), it is understood and acknowledged by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Securities for any specified term; (ii) past or future open market or other transactions by any Purchaser, specifically including, without limitation, Short Sales or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s publicly-traded securities; (iii) any Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, presently may have a “short” position in the Common Stock, and (iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction.

Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein, in which case they shall be accurate as of such date):

| 20 |

(a) Organization; Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b) Understandings or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business.

(c) Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act.

(d) Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

(e) Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Such Purchaser acknowledges and agrees that neither the Placement Agents nor any Affiliate of the Placement Agents have provided such Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary or desired. Neither the Placement Agents nor any of their Affiliates have made or make any representation as to the Company or the quality of the Securities and the Placement Agents and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser agrees need not be provided to it. In connection with the issuance of the Securities to such Purchaser, neither the Placement Agents nor any of their Affiliates have acted as a financial advisor or fiduciary to such Purchaser.

| 21 |

(f) Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth the material pricing terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement. Other than to other Persons party to this Agreement or to such Purchaser’s representatives, including, without limitation, its officers, directors, partners, legal and other advisors, employees, agents and Affiliates, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future.

The Company acknowledges and agrees that the representations contained in this Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transactions contemplated hereby.

The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication.

4.6 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented to the receipt of such information and agreed with the Company to keep such information confidential.

The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred.

The Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market.

For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

| 26 |

4.14 Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Disclosure Schedules.

4.15 Capital Changes. Until the one year anniversary of the Closing Date, the Company shall not undertake a reverse or forward stock split or reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority in interest of the Shares.

4.16 Exercise Procedures. The form of Notice of Exercise included in the Warrants set forth the totality of the procedures required of the Purchasers in order to exercise the Warrants. No additional legal opinion, other information or instructions shall be required of the Purchasers to exercise their Warrants. Without limiting the preceding sentences, no ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required in order to exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver Warrant Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

If any party shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under Section 4.8, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Action or Proceeding.

| 29 |

5.10 Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

5.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

5.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however, that in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).

| 30 |

5.14 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

5.15 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.16 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

5.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and its respective counsel have chosen to communicate with the Company through ML. ML does not represent any of the Purchasers and only represents the Placement Agents. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

| 31 |

5.18 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been canceled.

5.19 Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

5.20 Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.

5.21 WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
