QUESTIONS AND ANSWERS
ABOUT THE 2022 ANNUAL MEETING
The following questions and answers are intended to briefly address some commonly asked questions regarding the 2022 Annual Meeting. These questions and answers may not address all questions that may be important to you as a stockholder. You should read the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to or incorporated by reference in this proxy statement.

Q: | Why am I receiving these proxy materials?

A: | We have made these proxy materials available to you on the internet or have delivered paper proxy materials to you, because the board of directors (the “Board”) of Adverum Biotechnologies, Inc. (“Adverum,” “we,” “us” or “our”) is soliciting your proxy to vote at the 2022 Annual Meeting or any adjournments or postponements thereof that take place. As a stockholder, you are invited to attend the 2022 Annual Meeting and are requested to vote on the proposals described in this proxy statement. However, you do not need to attend the 2022 Annual Meeting to vote.

Q: | Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

A: | Pursuant to rules adopted by the Securities and Exchange Commission (“SEC”), we are generally providing access to our proxy materials over the internet rather than printing and mailing the proxy materials. We believe electronic delivery will expedite the receipt of materials and will help lower our costs and reduce the environmental impact of our annual meeting materials. Therefore, a notice of internet availability will be mailed to beneficial owners of our common stock starting on or about April 26, 2022. The notice of internet availability will provide instructions as to how stockholders may access and review the proxy materials, including the notice of annual meeting, proxy statement and Annual Report on Form 10-K, and how to vote, on the website referred to in the notice of internet availability or, alternatively, how to request that a copy of the proxy materials, including a proxy card, be sent to them by mail. In addition, stockholders of record will be sent the proxy materials in printed form or electronically by email and may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the notice of internet availability, and our notice of annual meeting, proxy statement and Annual Report on Form 10-K are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this document.

Q: | When and where is the 2022 Annual Meeting?

A: | The 2022 Annual Meeting will be held on June 10, 2022, at 8:00 a.m., Pacific Daylight Time via a live audio webcast at www.virtualshareholdermeeting.com/ADVM2022. You will not be able to attend the 2022 Annual Meeting in physically.

Q: | Why is the 2022 Annual Meeting being held in virtual-only format this year?

A: | Our Board annually considers the appropriate format of our annual meeting and this year has decided to hold a virtual annual meeting due to the COVID-19 global pandemic. In addition, we intend the virtual meeting format to provide stockholders a similar level of transparency to the traditional in-person meeting format and we will take steps to ensure such an experience. Our stockholders will be afforded the same opportunities to participate at the virtual 2022 Annual Meeting as they would at an in-person annual meeting of stockholders. Our virtual annual meeting will allow stockholders to submit questions beginning 30 minutes prior to the scheduled Annual Meeting start time and during the meeting. We will spend up to

TABLE OF CONTENTS

Internet proxy voting may be provided 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.

Q: | How many votes do I have?

A: | On each matter to be voted upon, you have one vote for each share of our common stock you held as of the Record Date.

Q: | What if I return a proxy card but do not make specific choices?

A: | If you return a signed and dated proxy card without marking any voting selections, your shares will be voted “FOR ALL” the Class II nominees for director named in this proxy statement, “FOR” the ratification of the selection of Ernst & Young LLP as the independent registered public accounting firm of Adverum for the year ending December 31, 2022, “FOR” the advisory approval of executive compensation, and “FOR” the proposal to approve the Adverum Biotechnologies, Inc. Amended and Restated 2014 Employee Stock Purchase Plan. If any other matter is properly presented at the 2022 Annual Meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Q: | Who is paying for this proxy solicitation?

A: | We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors, officers and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors, officers and employees will not be paid any additional compensation for soliciting proxies.

Q: | What does it mean if I receive more than one notice or proxy card?

A: | If you receive more than one notice or proxy card, your shares are registered in more than one name or are registered in different accounts. Please vote with respect to each notice, or complete, sign and return each proxy card to ensure that all of your shares are voted.

Q: | Can I change my vote after I have submitted my proxy?

A: | Yes. You can revoke your proxy at any time before it is exercised at the 2022 Annual Meeting. If you are the stockholder of record of your shares, you may revoke your proxy in any one of three ways:

• | You may submit another properly executed 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 Corporate Secretary at Adverum Biotechnologies, Inc., 100 Cardinal Way, Redwood City, California 94063.

• | You may attend the 2022 Annual Meeting, which will be held virtually via the Internet, and vote online. Simply attending the 2022 Annual Meeting will not, by itself, revoke your proxy.

If your shares are held by your broker or other agent, you should follow the instructions provided by your broker or agent.

Q: | What constitutes a quorum for purposes of the 2022 Annual Meeting?

A: | A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the issued and outstanding shares entitled to vote are present virtually or represented by proxy at the 2022 Annual Meeting. On the Record Date, there were 98,766,299 shares outstanding and entitled to vote. Thus, the holders of 49,383,150 shares must be present in person or represented by proxy at the meeting to have a quorum. As described above, stockholders attending the virtual meeting will be deemed to be attending in person, as provided by Delaware law, and their shares will be counted towards the quorum requirement.

TABLE OF CONTENTS

Abstentions and broker non-votes (as described below) will be counted towards the quorum requirement. If there is no quorum, the chairperson of the meeting or the holders of a majority of shares entitled to vote at the meeting and present or represented by proxy may adjourn the 2020 Annual Meeting to another date.

Q: | How are votes counted?

A: | Broadridge Financial Solutions, Inc. has been engaged as our independent agent to tabulate stockholder votes for the 2022 Annual Meeting (the “Inspector of Elections”). The Inspector of Elections will separately count: for Proposal No. 1 (the election of directors), “FOR,” “WITHHOLD” and broker non-votes; and for Proposal No. 2 (the ratification of the selection of Ernst & Young LLP as the independent registered public accounting firm of Adverum for the year ending December 31, 2022), Proposal No. 3 (the advisory approval of executive compensation), and Proposal No. 4 (the approval of the Adverum Biotechnologies, Inc. Amended and Restated 2014 Employee Stock Purchase Plan), votes “FOR” and “AGAINST,” abstentions and, if applicable, broker non-votes.

If your shares are held by your broker or other agent as your nominee (that is, held beneficially in “street name”), you will receive a voting instruction form from the institution that holds your shares. Please follow the instructions included on that form regarding how to instruct your broker or other agent to vote your shares. If you do not give voting instructions to your broker or other agent, your broker or other agent can only vote your shares with respect to “routine” matters (as described below).

Q: | What are “broker non-votes”?

A: | If you hold shares beneficially in street name and do not provide your broker with voting instructions, your shares may constitute “broker non-votes.” Broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. These matters are referred to as “non-routine” matters. Because brokers are permitted to vote on “routine” matters without instructions from the beneficial owner, broker non-votes do not occur with respect to such matters. Proposal No. 1 (election of directors), Proposal No. 3 (advisory approval of executive compensation), and Proposal No. 4 (the approval of the Adverum Biotechnologies, Inc. Amended and Restated 2014 Employee Stock Purchase Plan) are “non-routine matters,” but Proposal No. 2 (to ratify the selection of Ernst & Young LLP as the independent registered public accounting firm for Adverum for the year ending December 31, 2022) is a “routine” matter. Accordingly, if you do not instruct the broker how to vote your shares your broker will only be able to vote your shares with respect to Proposal No. 2, and will not be able to vote your shares with respect to Proposal Nos. 1, 3 or 4.

Q: | How many votes are needed to approve each proposal?

A: | The following votes are required to approve each proposal:

PROPOSAL NO. 1: ELECTION OF DIRECTORS
Board and Corporate Governance Highlights
Our Board is made up of directors with extensive experience leading and advising biotechnology and pharmaceutical companies. Our Board strives to ensure that our directors have backgrounds that collectively add significant value to our strategic decisions and enable them to provide oversight of management to ensure accountability to our stockholders. In addition, we have worked hard to strike the right balance between long-term understanding of our business and fresh external perspectives, as well as to ensure diversity within the boardroom.
We believe that a diversity of viewpoints, background, experience and other characteristics, such as gender, race, ethnicity, culture, nationality and sexual orientation, are an important part of the composition of our Board. To this end, in 2018 our Board adopted the so-called “Rooney Rule,” by amending our Corporate Governance Guidelines to provide that when evaluating candidates for nomination and new directors, the Board shall:

• | consider candidates with diverse backgrounds in terms of knowledge, experience, skills and other characteristics in the context of our needs at that point in time with a view to creating a Board with a diversity of experience and perspectives; and

• | include in the pool from which new director nominees are chosen by the Board candidates with a diversity of gender, race, ethnicity, culture, nationality or sexual orientation (and any third-party engaged to identify candidates for such pool will be asked to include such candidates).

Our Board’s Nominating and Corporate Governance Committee is responsible for making recommendations to our Board regarding candidates for directorships and composition and organization of our Board. Through their work, we have assembled a Board composed of members with diverse backgrounds, skills and experience, and we believe this diversity contributes to an effective and well-balanced Board that is able to provide valuable insight into, and effective oversight of, our senior management team.

General
Our Board is divided into three classes. Each class has a three-year term. Except as otherwise provided by law, vacancies on our Board may be filled only by individuals elected by a majority of the remaining directors. A director elected by our Board to fill a vacancy in a particular class, including a vacancy created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until such director’s successor is elected and has qualified, or until such director’s earlier death, resignation or removal.
Our Board currently consists of nine directors and no vacancies, divided into the three following classes:

• | The Class I directors are Soo Hong, Dawn Svoronos and Reed V. Tuckson, M.D., whose terms will expire at the 2024 Annual Meeting of Stockholders;

• | The Class II directors are Patrick Machado, Laurent Fischer, M.D. and James Scopa, whose terms will expire at the 2022 Annual Meeting of Stockholders and who are nominated for election to serve until the 2025 Annual Meeting of Stockholders; and

• | The Class III directors are Mark Lupher, Ph.D., Rabia Gurses Ozden, M.D. and Scott M. Whitcup, M.D., whose terms will expire at the 2023 Annual Meeting.

TABLE OF CONTENTS

The three nominees for Class II directors are Messrs. Machado and Scopa and Dr. Fischer, each of whom has agreed to stand for election as Class II directors. Each nominee was selected by the Board upon the unanimous recommendation of the Nominating and Corporate Governance Committee. Messrs. Machado and Scopa were previously elected to our Board by our stockholders. Dr. Fischer was appointed to our Board in June 2020 in connection with his appointment as our Chief Executive Officer. The specific experience, qualifications, attributes and skills of each nominee that led the Board to conclude that the individual should serve as a director are described in each nominee’s biography below. If elected, each nominee will serve for a three-year term expiring at the 2025 annual meeting of stockholders, or until his or her successor is elected and has qualified, or until his or her earlier death, resignation or removal.
Vote Required for Approval
Our directors are elected by a plurality of the votes cast. If a stockholder is voting by submitting a proxy card and a choice is specified on the proxy card by a stockholder, the shares will be voted as specified. If a choice is not specified on the proxy card, and authority to do so is not withheld, the shares will be voted “FOR” the election of the three nominees named above. If any of the nominees becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for the nominee may instead be voted for the election of a substitute nominee proposed by the Board. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.
Pursuant to our Bylaws, written notice by stockholders of qualifying nominations for election to our Board of Directors must have been received by our Corporate Secretary by February 11, 2022. We received one notice from a stockholder holding 200 shares indicating that he intended to nominate himself at the 2022 Annual Meeting but not solicit proxies. If this nomination is properly presented at the meeting, the management proxy holders intend to use their discretionary authority to vote for election of the Board’s nominees (and not this stockholder). No other nominations for election to our Board may be made by stockholders at the 2022 Annual Meeting.
OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR ALL” OF THE THREE CLASS II NOMINEES LISTED ABOVE FOR DIRECTOR. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED “FOR ALL” THE THREE CLASS II NOMINEES LISTED ABOVE FOR DIRECTOR.
Our nominees for director and directors continuing following the 2022 Annual Meeting and their ages as of April 15, 2022 are:

However, the Audit Committee is submitting the selection of Ernst & Young LLP to our stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain Ernst & Young LLP. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Adverum and our stockholders.

Accordingly, the Board is asking you to indicate your support for the compensation of our named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:
“RESOLVED, that the compensation paid to Adverum’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”
Because the vote is advisory, it is not binding on our Board, our Compensation Committee or us. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.
Advisory approval of this proposal requires “FOR” votes from the holders of a majority of the shares cast in person or by proxy (excluding abstentions and broker non-votes, if any).
Our stockholders have recommended, and our Board has approved, a frequency of each year for advisory votes on executive compensation. Accordingly, the next advisory vote on executive compensation will be at our 2023 Annual Meeting of Stockholders.
OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE ADVISORY VOTE ON EXECUTIVE COMPENSATION. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED “FOR” THE APPROVAL OF THIS PROPOSAL.

PROPOSAL NO. 4: APPROVAL OF THE ADVERUM BIOTECHNOLOGIES, INC.
AMENDED AND RESTATED 2014 EMPLOYEE STOCK PURCHASE PLAN
The Board of Directors is asking the stockholders to approve an amendment and restatement of our 2014 Employee Stock Purchase Plan (the “2014 ESPP”) to increase by 5,800,000 shares (from 3,000,000 shares to 8,800,000 shares) the number of shares of our common stock reserved for issuance under the 2014 ESPP.
The 2014 ESPP was approved by the Board on July 14, 2014 and by our stockholders on July 29, 2014, with subsequent non-material amendments that did not require stockholder approval. The 2014 ESPP is an employee benefit program that enables our qualified employees and our designated subsidiaries to purchase shares of our common stock through payroll deductions. The purposes of the 2014 ESPP are to assist our qualified employees and our certain designated subsidiaries in acquiring a stock ownership interest, as well as to encourage them to remain in the employ of us and our subsidiaries. The 2014 ESPP is intended to qualify for favorable federal income tax treatment under Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”).
We believe that the 2014 ESPP provides a valuable opportunity for employees to acquire an ownership interest in Adverum and provides stockholder value by aligning employee and stockholder interests. We rely on equity incentives to attract and retain our employees, and we believe that such incentives are essential to our long-term growth and future success. The proposed share increase will ensure that a sufficient reserve of common stock remains available under the 2014 ESPP to allow us to continue to provide these equity incentives to our employees on a competitive level.
We manage our long-term stockholder dilution by limiting the number of equity incentive awards granted annually. Our compensation committee carefully monitors our annual burn rate, dilution, and equity expense to ensure that we maximize stockholders’ 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 2014 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 2014 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 2014 ESPP. Under the terms of the proposed 2014 ESPP and the anticipated terms of the offerings, the number of shares of our common stock which a participant could purchase during any purchase period is limited to 6,000 shares. In addition, the fair market value of shares purchased by an individual participant in the 2014 ESPP may not exceed $25,000 in any calendar year.
Should our stockholders fail to approve the amendment and restatement of the 2014 ESPP, it will continue to remain in effect in accordance with its current terms. However, because only 2,130,542 shares of our common stock remained available for issuance under the 2014 ESPP as of April 15, 2022, our ability to use this form of equity-based compensation to attract, retain and motivate our employees in what is a very competitive hiring environment would be constrained based on our projected increase in headcount and employee participation in the future.
The 2014 ESPP, as amended and restated, is attached to this proxy statement as Appendix A and is incorporated herein by reference. The following description of the 2014 ESPP, as amended and restated, is a summary of certain important provisions and does not purport to be a complete description of the 2014 ESPP. Please see Appendix A for more detailed information.
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE AMENDMENT AND RESTATEMENT OF ADVERUM’S 2014 EMPLOYEE STOCK PURCHASE PLAN TO INCREASE THE NUMBER OF SHARES RESERVED FOR ISSUANCE.
Description of the 2014 ESPP
Shares Subject to the Plan. 208,333 shares of Common Stock were originally authorized for issuance under the 2014 ESPP. The 2014 ESPP also originally provided for an annual increase in the share pool on the first day of each year beginning in 2015 and ending in 2024, equal to the lesser of (i) one percent (1%) of the shares of Common Stock outstanding on the last day of the immediately preceding fiscal year and (ii) such number of
18

TABLE OF CONTENTS

shares of Common Stock as determined by the Board, but this “evergreen” provision is not being included in the amended and restated plan. The Board of Directors is seeking stockholder approval to add 5,800,000 additional shares to the 2014 ESPP, for a total of 8,800,000 shares of Common Stock. As of April 15, 2022, 2,130,542 shares remained available for issuance under the 2014 ESPP.
Administration. The 2014 ESPP may be administered by the Board of Directors or a committee of the Board of Directors designated by the Board of Directors (the “Administrator”). The Administrator has the authority to administer and interpret the 2014 ESPP and to make such rules and regulations as it deems necessary to administer the 2014 ESPP.
Eligible Employees. To participate in the 2014 ESPP, an individual employee must: (i) customarily work at least twenty hours per week, and (ii) customarily work more than five months in any calendar year. An employee is not eligible to participate or continue participation in the 2014 ESPP if the employee owns or will own, as a result of such participation, shares possessing 5% or more of the total combined voting power or value of all classes of stock of Adverum or any subsidiary. Non-employee directors of Adverum are not eligible to participate in the 2014 ESPP. As of April 15, 2022, approximately 114 employees of Adverum and its designated subsidiaries are eligible to participate in the 2014 ESPP.
Stock Purchases. Offerings under the 2014 ESPP are currently divided into 24-month offering periods, each of which is comprised of four purchase periods of approximately six months each. Subject to the limitations set forth in the 2014 ESPP, the Administrator has the authority to establish offering periods of alternative lengths and to establish different commencing and ending dates for such offering periods. During each offering period, participating employees accumulate funds in an account used to buy common stock through payroll deductions at a rate of not less than 1% or more than 15% of such participant’s base pay during each payroll period in the offering period.
At the end of each offering period, the purchase price is determined and the participating employees’ accumulated funds are used to purchase the appropriate number of shares of common stock. Under the 2014 ESPP, no participant may purchase more than $25,000 worth of common stock (based on the fair market value of the common stock on the date the option is granted) during any calendar year. In addition, the 2014 ESPP (as amended and restated) limits the number of shares of common stock that may be purchased by any one employee during each purchase period to 6,000 shares, but this limit can be increased or decreased by the Administrator with respect to future offerings.
Purchase Price. The purchase price per share of common stock is 85% of the lesser of (i) the fair market value of the common stock on the first day of an offering period and (ii) the fair market value of the common stock on the last day of an offering period. For purposes of the 2014 ESPP, “fair market value” means the closing price of the common stock on the Nasdaq Stock Market for such day. On April 19, 2022, the closing trading price for Adverum’s common stock was $1.12.
Effect of Termination of Employment. A participant is not eligible to continue his or her participation in the 2014 ESPP in the event of termination of employment for any reason. If termination occurs on or prior to the last business day of an offering period, the balance in the participant's account will be paid to the participant or to his or her estate or designated beneficiary. Neither payroll deductions credited to a participant’s account nor any rights with regard to the purchase of shares under the 2014 ESPP may be assigned, transferred, pledged or otherwise disposed of in any way by a participant, other than by will or the laws of descent and distribution.
Changes in Capitalization. The maximum number of shares of the common stock which will be made available for sale under the 2014 ESPP, the maximum number of shares each participant may purchase per offering period, the maximum number of shares that all participants may purchase per offering period, and the price per share and the number of shares of common stock covered by each option under the 2014 ESPP which has not yet been exercised will be proportionately adjusted for any increase or decrease in the number of issued shares of common stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the common stock, or any other change in the number of shares of Common Stock effected without receipt of consideration by Adverum.
Change in Control. In the event of certain mergers or consolidations, changes in the composition of the Board of Directors or acquisition by another corporation of all or substantially all of Adverum’s assets, the rights to purchase shares under the 2014 ESPP will be assumed or equivalent rights substituted by the successor
19

TABLE OF CONTENTS

corporation, or a parent or subsidiary of the successor corporation. If the successor corporation refuses to assume or substitute for such rights or in the event of a dissolution or liquidation of Adverum, the offering period during which a participant may purchase stock will be shortened and a new exercise date will be set.
Amendment of the 2014 ESPP. The Administrator has the power to amend or terminate the 2014 ESPP, provided that amendments will also require stockholder approval if necessary to comply with Code Section 423 or any other applicable law or regulation.
Term of the Plan. The 2014 ESPP will continue in effect until terminated by the Administrator.
Federal Income Tax Consequences
The following is a summary of certain material federal income tax consequences associated with the grant and exercise of purchase rights under the 2014 ESPP. The summary does not address tax rates or non-U.S., state or local tax consequences, nor does it address employment tax or other federal tax consequences except as noted.
The 2014 ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. In general, an employee will not recognize U.S. taxable income until the sale or other disposition of the shares of our common stock purchased under the 2014 ESPP (“ESPP Shares”). Upon such sale or disposition, the employee will generally be subject to tax in an amount that depends on the employee’s holding period with respect to the ESPP Shares.
If the ESPP Shares are sold or disposed of more than one year from the date of purchase and more than two years after the first day of the offering period in which they were purchased, or upon the employee’s death while owning the ESPP Shares, the employee will recognize ordinary income in an amount generally equal to the lesser of: (i) an amount equal to 15% of the fair market value of the ESPP Shares on the first day of the offering period (or such other percentage equal to the applicable purchase price discount), and (ii) the excess of the sale price of the ESPP Shares over the purchase price. Any additional gain will be treated as long-term capital gain. If the ESPP Shares held for the periods described above are sold and the sale price is less than the purchase price, then the employee will recognize a long-term capital loss in an amount equal to the excess of the purchase price over the sale price of the ESPP Shares.
If the ESPP Shares are sold or otherwise disposed of before the expiration of the holding periods described above, other than following the employee’s death while owning the ESPP Shares, the employee generally will recognize as ordinary income an amount equal to the excess of the fair market value of the ESPP Shares on the date the ESPP Shares were purchased over the purchase price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on the employee’s holding period with respect to the ESPP Shares.
We are not entitled to a deduction for amounts taxed as ordinary income or capital gain to an employee except to the extent of ordinary income recognized upon a sale or disposition of ESPP Shares prior to the expiration of the holding periods described above.
New Plan Benefits
Because participation in the 2014 ESPP is entirely within the discretion of the eligible employees, a new plan benefits table, as described in the federal proxy rules, is not provided. Because we cannot predict the participation levels by employees, the rate of employee contributions or the eventual purchase price under the 2014 ESPP, it is not possible to determine the value of benefits that may be obtained by executive officers and other employees under the 2014 ESPP. Non-employee directors are not eligible to participate in the 2014 ESPP.

TABLE OF CONTENTS

CORPORATE GOVERNANCE
Code of Business Conduct and Ethics
We have adopted a code of business conduct and ethics that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. The code of business conduct and ethics is available on our website at http://investors.adverum.com. We expect that any amendments to the code, or any waivers of its requirements, will be disclosed on our website. The reference to our website does not constitute incorporation by reference of the information contained at or available through our website.
Corporate Governance Guidelines
We believe in sound corporate governance practices and have adopted formal Corporate Governance Guidelines to enhance our effectiveness. Our Board adopted these Corporate Governance Guidelines to ensure that it has the necessary practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Corporate Governance Guidelines are also intended to align the interests of our directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices our Board follows with respect to Board and committee composition and selection, board meetings, Chief Executive Officer performance evaluation and management development and succession planning for senior management, including the Chief Executive Officer position. A copy of our Corporate Governance Guidelines is available on our website at http://investors.adverum.com.
Board Composition
Director Independence
Our common stock is listed on The Nasdaq Global Market. Rule 5605 of the Marketplace Rules of the Nasdaq Stock Market LLC (the “Nasdaq Listing Rules”) requires that independent directors compose a majority of a listed company’s board of directors within one year of listing. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit and compensation committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act. Under Nasdaq Listing Rule 5605(a)(2), a director will only qualify as an “independent director” if, in the opinion of the board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Nasdaq Listing Rule 5605(a)(2) also specifies certain categories of persons who will not be considered independent, including employees, family members of executive officers and recipients of compensation from the company in excess of $120,000 during any period of twelve consecutive months within the past three years, subject to certain exceptions. To be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries. In addition to satisfying general independence requirements under the Nasdaq Listing Rules, members of the compensation committee must also satisfy additional independence requirements set forth in Nasdaq Listing Rule 5605(d)(2). To be considered independent for purposes of Nasdaq Listing Rule 5605(d)(2), our Board must consider all factors specifically relevant to determining whether a director has a relationship with us which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by us to such director; and whether such director is affiliated with us, a subsidiary of our company or an affiliate of a subsidiary of our company.
In March 2022, our Board undertook a review of the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that each of Ms. Hong, Dr. Lupher, Mr. Machado, Dr. Ozden, Mr. Scopa, Ms. Svoronos, Dr. Tuckson, and Dr. Whitcup is independent within the meaning of Rule 5605 of the Nasdaq Listing Rules. Our Board also determined that Mr. Machado, Mr. Scopa, and Ms. Svoronos, who compose our Audit Committee, and Mr. Machado, Mr. Scopa, and Dr. Tuckson, who compose our Compensation Committee, satisfy the independence standards for those committees established by applicable SEC rules and Nasdaq Listing Rules. In making these determinations, our Board considered the current and prior relationships that each
22

TABLE OF CONTENTS

non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence. For example, the Board considered (i) with respect to Mr. Machado and Ms. Svoronos, the fact that both Mr. Machado and Ms. Svoronos serve on the board of directors of Xenon Pharmaceuticals, Inc. and (ii) with respect to Dr. Tuckson, the fact that both Dr. Tuckson and Dr. Fischer serve on the board of directors of CTI Biopharma Corp. The Board also previously determined that Rekha Hemrajani, who served on our Audit Committee during a portion of 2021, Dr. Eric Carter and Dr. Thomas Woiwode, who served on our Compensation Committee and Nominating and Corporate Governance Committee during a portion of 2021, satisfied the independence standards for those committees established by applicable SEC rules and Nasdaq Listing Rules.
Classified Board of Directors
In accordance with our amended and restated certificate of incorporation, our Board is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following their election.
We feel strongly that, given the long runway for drug therapy development and given the stage and size of the Adverum, as well as our current priority focus on restoring the clinical trials roadmap in support of our long-term growth, a classified Board is appropriate at the current time.
Leadership Structure of our Board
Our amended and restated Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer and/or appoint a lead director in accordance with its determination that utilizing one or the other structure would be in the best interests of our company. The roles of Chair of the Board and Chief Executive Officer are currently filled by Mr. Machado and Dr. Fischer, respectively.
Mr. Machado has served as Chair of the Board since May 2019. Mr. Machado’s tenure on the Board, his experience in serving on multiple other biotechnology company boards, as well as the deep knowledge of our company gained in his role as a member of the Audit Committee of the Board, allow him to provide valuable insights and facilitate the implementation of our strategic initiatives and business plans. In our view, having a Chair that is far removed from management would have the potential to give rise to divided leadership, which could interfere with good decision making or weaken our ability to develop and implement strategy. The Board also believes, however, that Mr. Machado’s independence is an essential complement to his familiarity with our company and management representation on the Board, helping to foster an environment that is conducive to objective evaluation and oversight of management’s performance.
Board Qualifications
The Nominating and Corporate Governance Committee is responsible for reviewing with the Board, on an annual basis, the appropriate characteristics, skills and experience required for the Board as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including: personal and professional integrity, ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; strong finance experience; experience relevant to our industry; experience as a director or executive officer of another publicly held company; diversity of expertise and experience in substantive matters pertaining to our business relative to other Board members; diversity of background and perspective; and practical and mature business judgment, including the ability to make independent analytical inquiries. The Board believes that diversity of viewpoints, background, experience and other characteristics are an important part of its makeup, and it actively seeks these characteristics in identifying director candidates. The Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In addition, the Board evaluates each individual’s other professional commitments against their personal capacity to ensure they have adequate time and flexibility to execute their Board duties.
In searching for qualified director candidates to fill vacancies in the Board, the Nominating and Corporate Governance Committee solicits our Board for names of potentially qualified candidates. Additionally, the Nominating
23

TABLE OF CONTENTS

and Corporate Governance Committee may request that members of the Board pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee then considers the potential pool of director candidates, selects the candidate the committee believes best meets the then-current needs of the Board, and conducts a thorough investigation of the proposed candidate’s background to ensure there is no past history that would cause the candidate not to be qualified to serve as a member of our Board.
To fulfill its responsibility to recruit and recommend to the Board nominees for election as directors, the Nominating and Corporate Governance Committee considers all qualified candidates who may be identified by any one of the following sources: current or former Board members, a professional search firm, Adverum executives or stockholders.
In response to feedback received from our stockholders, we added two additional female directors to our Board to increase the total Board composition to three female directors (33% of directors). The two additional female directors added are Rabia Gurses Ozden, M.D. and Soo Hong, M.B.A. Dr. Ozden has extensive experience in ophthalmology, clinical development and operations, pharmacovigilance, regulatory affairs and gene therapy. Ms. Hong brings a deep expertise in human capital management, executive and leadership development as well as executive and board compensation design and governance serving rapidly growing organizations during periods of transformation.
Stockholders who wish to make a recommendation or propose a director candidate for consideration by the Nominating and Governance Committee may do so by submitting the candidate’s name, resume and biographical information and qualifications to the attention of the Corporate Secretary, Adverum Biotechnologies, Inc., 100 Cardinal Way, Redwood City, California 94063. All recommendations received by the Corporate Secretary will be presented to the Nominating and Governance Committee for its consideration.
We may request from the nominating stockholder or nominating stockholder group such other information as may reasonably be required to determine whether each person recommended by a stockholder or stockholder group as a nominee meets any minimum requirements that may be established by our Board and to enable us to make appropriate disclosures to stockholders entitled to vote in the next election of directors. Proposed nominees are required to make themselves reasonably available to be interviewed by the Nominating and Corporate Governance Committee and members of management, as determined to be appropriate by the Nominating and Corporate Governance Committee. We will not accept a stockholder recommendation for a nominee if the recommended candidate’s candidacy or, if elected, Board membership, would violate applicable state law, federal law or the rules of any exchange or market on which our securities are listed or traded. If the proposed nomination by stockholders was made in accordance with the procedures in our amended and restated bylaws, the Nominating and Corporate Governance Committee will apply the same criteria in evaluating the proposed nominee as it would any other Board nominee candidate and will recommend to our Board whether or not the proposed stockholder nominee should be nominated by our Board and included in our proxy statement.
Stockholders who wish to nominate a director for election at an upcoming annual meeting of stockholders must comply with the advance notice provisions in our amended and restated bylaws. Each stockholder making a nomination is required to provide certain information, representations and undertakings as outlined in our amended and restated bylaws. The Nominating and Corporate Governance Committee will consider director candidates recommended by our stockholders. If a stockholder submits a proposed nominee, the Nominating and Corporate Governance Committee will consider the proposed nominee, along with any other proposed nominees recommended by members of the Board, in the same manner in which the Nominating and Corporate Governance Committee would evaluate its nominees for director. For a description of the proper procedure for stockholder nominations, see “Procedures for Nominations of Directors by Stockholders” in this proxy statement.
Role of Board in Risk Oversight Process
We are exposed to a number of risks, including economic, environmental, operational, and regulatory risks, as well as risks resulting from the COVID-19 pandemic, among others. Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with our Board at regular meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.
24

TABLE OF CONTENTS

Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure and key enterprise risks, and our Audit Committee is responsible for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. The Board or appropriate Board committees discuss selected risks in more detail throughout the year, including the COVID-19 pandemic and its related risks.
Board Committees
Our Board has three primary committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee, which are described below. In addition, the Board has a Research and Development Committee.
Audit Committee
Our Audit Committee oversees our corporate accounting and financial reporting process. Among other matters, the Audit Committee:

• | appoints our independent registered public accounting firm;

• | evaluates the independent registered public accounting firm’s qualifications, independence and performance;

• | determines the engagement of the independent registered public accounting firm;

• | reviews and approves the scope of the annual audit and the audit fee;

• | discusses with management and the independent registered public accounting firm the results of the annual audit and the review of our quarterly consolidated financial statements;

• | approves the retention of the independent registered public accounting firm to perform any proposed permissible audit and non-audit services;

• | is responsible for reviewing our consolidated financial statements and our management’s discussion and analysis of financial condition and results of operations to be included in our annual and quarterly reports to be filed with the SEC;

• | reviews our critical accounting policies and estimates;

• | reviews related party transactions; and

• | annually reviews the Audit Committee charter and the Audit Committee’s performance.

The current members of our Audit Committee are Mr. Machado (Chair), Mr. Scopa and Ms. Svoronos. Ms. Hemrajani also served on our Audit Committee during a portion of 2021. Mr. Machado serves as the chair of the Audit Committee. All members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and the Nasdaq Listing Rules. Our Board has determined that Mr. Machado is an Audit Committee financial expert as defined under the applicable rules of the SEC and has the requisite financial sophistication as defined under the Nasdaq Listing Rules.
The Audit Committee operates under a written charter that satisfies the applicable rules and regulation of the SEC and the Nasdaq Listing Rules. A copy of the Audit Committee charter is available on our website at http://investors.adverum.com.
Compensation Committee
Our Compensation Committee reviews and approves, or may recommend to the full Board or independent members of the Board, as applicable, policies relating to compensation and benefits of our officers, directors and employees. The Compensation Committee reviews and approves corporate goals and objectives relevant to
25

TABLE OF CONTENTS

compensation of our Chief Executive Officer and other executive officers, evaluates the performance of these officers in light of those goals and objectives, and sets or makes recommendations to our Board regarding the compensation of these officers based on such evaluations. Our Board retains the authority to determine and approve, upon the recommendation of the Compensation Committee, the compensation of the Chief Executive Officer, unless such authority has been delegated to the Compensation Committee. The Compensation Committee also approves grants of stock options and other awards under our stock plans. In fulfilling its responsibilities, the Compensation Committee may delegate any or all of its responsibilities to a subcommittee of the Compensation Committee, but only to the extent consistent with our amended and restated certificate of incorporation, amended and restated bylaws, applicable Nasdaq Listing Rules, and other applicable law. The Compensation Committee will periodically review and evaluate the performance of the Compensation Committee and its members, including an annual review of its charter. The current members of our Compensation Committee are Mr. Scopa (Chair), Mr. Machado and Dr. Tuckson. Dr. Carter also served on our Compensation Committee during a portion of 2021.
Each of the current members of our Compensation Committee is independent under the Nasdaq Listing Rules and regulations and is a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act.
Since 2019, Radford, a national executive compensation consulting firm, which is part of the Rewards Solutions practice at Aon plc, has been engaged by the Compensation Committee to conduct market research and analysis to assist the Compensation Committee in developing appropriate compensation and incentives for our executive officers, to advise the Compensation Committee and provide ongoing recommendations regarding material executive compensation decisions, and to review compensation proposals from management. Radford reports directly to the Compensation Committee and does not provide any non-compensation-related services to us. After review and consultation with Radford, the Compensation Committee determined that Radford is independent and that there is no conflict of interest resulting from retaining Radford. In reaching these conclusions, our Compensation Committee considered the factors set forth in SEC rules and the Nasdaq Listing Rules.
Our executive officers submit proposals to our Board and Compensation Committee regarding our executive and director compensation. Our Chief Executive Officer provides feedback and recommendations to our Compensation Committee with respect to executive compensation, other than his own compensation, including with regard to senior executive performance, responsibility and experience levels. The Compensation Committee often takes into consideration both our Chief Executive Officer’s input and the input of other senior executives in setting compensation levels.
The Compensation Committee operates under a written charter that satisfies the applicable rules and regulations of the SEC and the Nasdaq Listing Rules. A copy of the Compensation Committee charter is available on our website at http://investors.adverum.com.
Nominating and Corporate Governance Committee
The Nominating and Corporate Governance Committee is responsible for making recommendations to our Board regarding candidates for directorships and composition and organization of our Board. In addition, the Nominating and Corporate Governance Committee is responsible for overseeing our corporate governance policies and reporting and making recommendations to our Board concerning governance matters. The current members of our Nominating and Corporate Governance Committee are Ms. Svoronos (Chair), Dr. Lupher, Drs. Tuckson and Whitcup. Drs.

TABLE OF CONTENTS

Meetings of the Board of Directors and Committees
During 2021, our Board met nine times, the Audit Committee met four times, the Compensation Committee met eight times, the Nominating and Corporate Governance Committee met four times and the Research and Development Committee met two times. In 2021, each director attended at least 75% of the meetings of our Board and the committees on which the director served that were held while the person was a member of the applicable committee, except for Dr. Woiwode.
Limitation on Liability and Indemnification Matters
Our amended and restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:

• | any breach of the director’s duty of loyalty to us or our stockholders;

• | any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

• | unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

• | any transaction from which the director derived an improper personal benefit.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that we are required to indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. Our amended and restated bylaws also provide that we are obligated to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under Delaware law. We have entered, and expect to continue to enter, into agreements to indemnify our directors, executive officers and other employees as determined by our Board. We have entered into an indemnification agreement with each of our directors, including each of our Board's nominees for director. With specified exceptions, these agreements provide for indemnification for related expenses, including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain directors’ and officers’ liability insurance.
The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and our stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damages. To the extent the indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
Director Attendance at Annual Meetings
Although our directors are encouraged to attend our annual meetings, attendance is not mandatory. All of our then current directors attended the 2021 Annual Meeting of Stockholders. Our Board and management team encourage all of our directors to attend the virtual 2022 Annual Meeting.
Stockholder Communications with the Board of Directors
We provide a process for stockholders to send communications to our Board, the non-employee members of the Board as a group or any of the directors individually. Stockholders may contact any of the directors, including the non-employee directors, by writing to them c/o the Corporate Secretary, Adverum Biotechnologies, Inc., 100 Cardinal Way, Redwood City, California 94063. All communications will be compiled by our Corporate Secretary and submitted to our Board or individual directors, as applicable, on a periodic basis.

TABLE OF CONTENTS

Procedures for Nomination of Directors by Stockholders
Stockholders who wish to nominate a director for election at an upcoming annual meeting of stockholders must comply with the advance notice provisions in our amended and restated bylaws. Each stockholder making a nomination is required to provide certain information, representations and undertakings as outlined in our amended and restated bylaws.
We may request from the nominating stockholder or nominating stockholder group such other information as may reasonably be required to determine whether each person proposed to be nominated by a stockholder or stockholder group meets any minimum requirements that may be established by our Board and to enable us to make appropriate disclosures to stockholders entitled to vote in the next election of directors. Proposed nominees are required to make themselves reasonably available to be interviewed by the Nominating and Corporate Governance Committee and members of management, as determined to be appropriate by the Nominating and Corporate Governance Committee. We will not accept a stockholder nomination if the nominee’s candidacy or, if elected, Board membership would violate applicable state law, federal law or the rules of any exchange or market on which our securities are listed or traded. If the proposed nomination by stockholders was made in accordance with the procedures in our bylaws, the Nominating and Corporate Governance Committee will apply the same criteria in evaluating the proposed nominee as it would any other Board nominee candidate and will recommend to our Board whether or not the proposed stockholder nominee should be nominated by our Board and included in our proxy statement.
Notices of nominations should be directed to the attention of the Corporate Secretary, Adverum Biotechnologies, Inc., 100 Cardinal Way, Redwood City, California 94063, and must be received only during the period specified above under “When are stockholder proposals due for next year’s annual meeting?” in the section “Questions and Answers about the 2022 Annual Meeting.”
Prohibition on Hedging
Our insider trading policy, which applies to all of our officers, directors, and employees, prohibits hedging and monetization transactions, such as zero-cost collars and forward sale contracts, that allow individuals to continue to own the covered securities but without the full risks of ownership. Margin purchases, holding securities in a “margin account,” and pledging our securities as collateral to secure loans is also prohibited.
Environmental and Social Responsibility
At Adverum, our values define how we conduct business, shape patient care, apply science to medicine, and work and grow as a company. We strive to put our corporate values into action every day - by reducing the environmental impact of our research and operations, providing safe, engaging and impactful work for our employees, and always leading with integrity.
Our Core Values

• | Lead with integrity: We take individual and collective responsibility to advance evidence-based science as we embark on a bold mission.

• | Strive together: We tackle complex issues through diverse perspectives, shared decision-making, and collaboration.

• | Pioneer with patients: We use our science, technology, and expertise to innovate and optimize breakthrough products that give sight to patients across the globe.

We integrate environmental, social, and governance objectives into our decision-making with the goal of delivering long-term value to all of our stakeholders. Our leadership creates and monitors our sustainability-related programs, with our Board maintaining ultimate oversight.
To identify the sustainability issues material to our business, we are guided by best practices, feedback we receive from our stakeholders, including employees, regulators, patients and investors, and third-party thought leaders, such as the Sustainability Accounting Standards Board (SASB), Biotechnology and Pharmaceuticals.
Additional information regarding Adverum’s environmental and social practices is included in the “Sustainability” subsection of the “Company” section of our website. Information on our website is NOT incorporated by reference in this proxy statement.

NON-EMPLOYEE DIRECTOR COMPENSATION
Overview
The Compensation Committee reviews pay levels for non-employee directors periodically with assistance from its compensation consultant, Radford, which prepares a comprehensive assessment of our non-employee director compensation program. That assessment includes benchmarking of director compensation against the same peer group used for executive compensation purposes, an update on recent trends in director compensation and a review of related corporate governance best practices. Following that review, either the Compensation Committee or the Board, consistent with the recommendation of the Compensation Committee, has determined the non-employee director compensation program that will be in effect until the next such determination.
Non-Employee Director Compensation Policy
Under our non-employee director compensation policy, each non-employee director receives the following cash compensation for Board and standing committee service, as applicable:

• | $40,000 per year for service as a Board member;

• | $35,000 per year for service as a non-employee Chair of our Board;

• | $20,000 per year for service as chair of the Audit Committee;

• | $15,000 per year for service as chair of the Compensation Committee;

• | $10,000 per year for service as chair of the Nominating and Corporate Governance Committee;

• | $15,000 per year for service as chair of the Research and Development Committee;

• | $10,000 per year for service as non-chair member of the Audit Committee;

• | $7,500 per year for service as non-chair member of the Compensation Committee;

• | $5,000 per year for service as non-chair member of the Nominating and Corporate Governance Committee; and

• | $7,500 per year for service as non-chair member of the Research and Development Committee.

Annual cash retainers for service as a non-employee Chair of our Board, chair of a committee or non-chair member of the committee are in addition to the annual cash retainer for service as a Board member. Cash retainers are prorated for any partial years of service. We also reimburse our non-employee directors for their reasonable out-of-pocket expenses incurred in attending Board and committee meetings.
Option Awards
Pursuant to our non-employee director compensation policy, the non-employee directors receive grants of non-statutory stock options under our 2014 Equity Incentive Plan (the “2014 Plan”). For purposes of these awards, a non-employee director is a director who is not employed by us. Pursuant to our non-employee director compensation policy as in effect through March 30, 2021, each non-employee director who joined the Board was automatically granted an option to purchase 45,000 shares of our common stock (an “Initial Grant”). Initial Grants vest ratably in annual installments over three years of service following the date of grant.
In addition, pursuant to our non-employee director compensation policy as in effect during 2021 through March 30, 2021, on the date of our annual meeting of stockholders, (i) each non-employee director receives an annual equity award under our 2014 Plan of options to purchase 30,000 shares of our common stock (a “Board Annual Award”) and (ii) the Chair of the Board receives an additional option to purchase 10,000 shares of common stock (a “Chair Additional Annual Award”). The Board Annual Awards and Chair Additional Annual Awards vest in full on the earlier to occur of the first anniversary of the grant date or the next annual meeting (18 months from the date of grant or the 2022 Annual Meeting of stockholders in the case of the grant pursuant to (ii) above). All such options have a maximum term of ten years. Effective March 31, 2021, our non-employee director compensation policy was amended to enable us to maintain alignment of our director equity compensation with our peer group as stock prices fluctuate. Under the amended policy, each Initial Grant covers a number of shares having a grant-date fair value (determined as provided in the plan) of $520,000, each Board Annual Award covers a number of shares having a grant-date fair value of $260,000 and each Chair Additional Annual Award covers a number of shares having a grant-date fair value of $90,000.

More than 90% of our CEO compensation and more than 80% of the compensation for our other Named Executive Officers is variable and at risk, tied to our stock price performance or achievement of pre-set rigorous performance targets that are important to our stockholders.

Realized compensation received by our CEO since joining Adverum in 2020 is significantly below the total compensation reported in the Summary Compensation Table. Underscoring a robust alignment of our executive compensation program with stockholders’ interests, the sign-on stock option award issued to the Chief Executive Officer in 2020 is underwater, even though the clinical trials strategy designed to ensure safety and leading to the suspected unexpected serious adverse reaction (“SUSAR”) event was put in place before he joined Adverum.

TABLE OF CONTENTS

The chart below illustrates the difference between compensation actually realized by our CEO and pay reported in the Summary Compensation Table, for each of 2020 and 2021. “Realized compensation” for this purpose includes amounts paid only for salary and annual cash bonus. No options were exercised and no portion of the performance stock units granted in 2021 was earned.

• | Our 2021 annual incentive program comprised two separate half-year performance periods to support our response to the SUSAR event that occurred in April 2021 and to incentivize progress toward our strategic priorities. Based on the combined performance results for the two performance periods during 2021, the annual incentive program paid out at 80% of target for the CEO.

• | To incentivize accelerated achievement of the clinical trial milestones and to stabilize the leadership team, following several executive leadership departures, we implemented a special equity incentive performance program. The special awards were delivered in a mix of performance stock units with vesting tied to the achievement of rigorous strategic milestones and stock options that deliver value, only if our stock price appreciates.

• | Following the 2021 say-on-pay vote, our directors conducted an extensive stockholder outreach effort. Our Chair of the Board, as well as the Chairs of our Compensation Committee and Nominating and Corporate Governance Committee, led the stockholder engagement effort. We reached out to stockholders representing over 55% of our common stock and engaged with stockholders collectively holding approximately 31% of our common stock.

• | In response to our stockholder perspectives, the Compensation Committee implemented several executive compensation program changes, including the following:

○ | Enhanced transparency around the executive compensation program design and its alignment with our long-term strategy by including a full Compensation Discussion and Analysis disclosure in this year’s proxy filing.

○ | Updated our peer group in the second half of 2021 to reflect changes in our market capitalization and to ensure our executive compensation opportunities are aligned with the comparable market benchmarks.

○ | Introduced performance stock units into our 2021 special incentive program for executives to incentivize progress toward strategic milestones.

2021 Business and Performance Highlights

• | In July 2021, Adverum revised its ADVM-022 development plan to focus on advancing ADVM-022 for the treatment of wet AMD.

• | In October 2021, we presented two-year follow-up data from our Phase 1 OPTIC study in wet AMD patients at the Retina Society’s 54th Annual Scientific Meeting. The data presented demonstrated a greater than 80% reduction in annualized anti-VEGF injections following the 2E11 vg/eye ADVM-022 IVT injection that is expected to be validated in the Phase 2 study.

• | In December 2021, we finalized a two-dose study design for phase 2 trial of ADVM-022 in Wet AMD with intention to dose first patient in third quarter of 2022.

Fiscal performance ended December 31, 2021

• | Cash, cash equivalents and short-term investments were $305.2 million as of December 31, 2021, compared to $332.7 million as of September 30, 2021, and $429.7 million as of December 31, 2020. We expect the year-end cash position to fund operations into 2024.

Strategic Milestones

• | First Quarter of 2022: Granted Orphan Drug Designation (ODD) by the U.S. Food and Drug Administration for ADVM-062 (AAV/7m8-L-opsin), a novel gene therapy product candidate developed as a potential single IVT administration for the treatment of blue cone monochromacy by delivering a functional copy of the OPN1LW gene.

• | Second Quarter of 2022: Received requested Type C meeting feedback from the U.S. Food and Drug Administration related to our planned Phase 2 trial of ADVM-022 in wet age-related macular degeneration (wet AMD). We requested the FDA’s feedback to ensure alignment with the regulatory agency ahead of filing the Investigational New Drug (IND) amendment for the Phase 2 trial. The trial is designed to evaluate the 2 X 10^11 vg/eye dose and a new, lower 6 X 10^10 vg/eye dose of ADVM-022, along with new enhanced prophylactic steroid regimens, including local steroids and a combination of local and systemic steroids.

Clinical Trials Roadmap

• | Mid-2022 – Complete IND amendment process to enable initiation of Phase 2 trial of ADVM-022 in wet AMD

• | Third Quarter of 2022 – Plan to dose first patient in a Phase 2 trial of ADVM-022 in wet AMD

Stockholder Engagement and Our 2021 Say-On-Pay Vote Result
At our 2021 Annual Meeting, the advisory say-on-pay proposal received support of approximately 61% of votes cast compared to approximately 98% in 2020.
Following the 2021 say-on-pay vote and in response to the significant decline in stockholder support, the Compensation Committee expanded our stockholder outreach effort. We reached out to our top 17 stockholders collectively holding over 55% of our common stock and had meetings with six of these stockholders collectively representing approximately 31% of our common stock. The topics discussed with our stockholders included our

TABLE OF CONTENTS

corporate strategy, executive compensation program, board diversity and sustainability issues. Our Chair of the Board, Patrick Machado, our Chair of the Compensation Committee Chair, James Scopa, and our Chair of the Nominating and Governance Committee, Dawn Svoronos, led these discussions.
The perspectives we heard from our stockholders were conveyed to all members of the Board of Directors and were reviewed and considered by the relevant Board committees. Below is a summary of the feedback we received since our 2021 Annual Meeting and how we have responded:

What We Heard | ​ | ​ | Our Actions and Perspective
Executive Compensation Program Disclosure | ​ | ​ | Limited disclosure around the executive compensation program and its alignment with long-term value creation | ​ | ​ | ✔ Expanded our 2022 proxy disclosure by including a full Compensation Discussion and Analysis section that contains a detailed overview of the considerations that informed the Compensation Committee’s decisions regarding our 2021 executive compensation program. | ​ | ​ | Perspective: As a Smaller Reporting Company (SRC), we are not required to prepare a full Compensation Discussion and Analysis disclosure. To enable our stockholders to meaningfully assess our compensation practices and in response to their feedback, we are nevertheless enhancing our disclosure by including a detailed narrative around the peer group selection criteria, executive compensation program philosophy and its alignment with our corporate strategy and stockholder value creation.
CEO Sign-On Equity Award | ​ | ​ | Concerns with the quantum of the 2020 sign-on equity award provided to our CEO upon joining Adverum | ​ | ​ | ✔ Updated our peer group in the second half of 2021 to reflect changes in our market capitalization and to ensure our executive compensation opportunities are aligned with the comparable market benchmarks. | ​ | ​ | Perspective: Our Board of Directors and the Compensation Committee heard from our stockholders that the 2020 sign-on award to our Chief Executive Officer was deemed to be significant and took this feedback seriously. We typically issue front-loaded equity awards to our executives to incentivize them to accept our offer and to create immediate alignment with our long-term performance and stockholders’ interests upon joining Adverum. The sign-on package for our CEO was designed to attract executive talent of Dr. Fischer’s caliber to join our company and reflected his deep and extensive experience and knowledge of our industry and the leadership he was bringing to our Company. Stock options have no value until our stock price demonstrates meaningful appreciation, which is illustrated by the current valuation of the CEO’s 2020 option award that is significantly underwater.
Long-Term Incentive Program Structure | ​ | ​ | Limited ratio of performance incentives in the executive compensation program design | ​ | ​ | ✔ Incorporated performance stock units into the special incentive program for the NEOs that was implemented in the second half of 2021. | ​ | ​ | Perspective: The value of special performance incentives issued in the second half of 2021 was delivered in a mix of 61% performance stock units with vesting tied to the achievement of the pre-set rigorous performance milestones and 39% stock options that deliver value only if our stock price appreciates.

TABLE OF CONTENTS

The Compensation Committee and the Board will continue to consider stockholder feedback and the outcomes of the future say-on-pay votes when evaluating our executive compensation programs and policies and making compensation decisions for our NEOs.
Compensation Philosophy and Objectives
We believe in the importance of aligning the financial interests of our executives with those of our stockholders. A significant portion of our named executive officers’ compensation is designed to be variable and tied to the achievement of key financial and strategic performance objectives, the performance of our stock price, or both, which helps us to incentivize our executive officers to create long-term value for our stockholders.
In particular, the compensation programs have been designed to accomplish the following objectives:

• | Establish competitive compensation plans to attract, retain and motivate high performing senior leaders;

• | Emphasize a pay-for-performance culture to reward both annual and long-term Company performance while not encouraging excessive risk-taking;

• | Create long-term alignment between the senior executives and the stockholders’ interests;

• | Support our strategic initiatives and financial goals.

Compensation Decision Making Process
Role of the Compensation Committee
The Compensation Committee of our Board of Directors oversees our executive compensation program and is responsible for reviewing and approving all compensation of our executive officers, including its NEOs, authorizing stock incentive compensation, approving other incentive arrangements, and authorizing related agreements. During the fourth quarter of the year the Compensation Committee meets to begin planning for executive compensation the following year. Its activities include undertaking a preliminary assessment of the goals achievement for the current calendar year, setting our compensation peer group, reviewing current market data with respect to cash and equity compensation of our executives and establishing the performance measures which will be used to determine each executive officer’s annual cash bonus opportunities during the following year. In the first quarter of the year, the Compensation Committee meets to review and approve the achievement level of our prior year goals, sets the executive officers’ base salaries, target annual cash and equity incentive opportunities in alignment with our overall compensation philosophy.
Role of the Independent External Advisor
The Compensation Committee retained Aon’s Human Capital Solutions practice, a division of Aon plc (formerly known as Radford) (“Aon”) to serve as its independent compensation consultant. In this role, Aon reports directly to the Compensation Committee and uses the competitive market data described below to provide the Committee with compensation ranges that are consistent with our compensation peer group. The Compensation Committee considers analysis and advice from Aon when making compensation decisions related to our Chief Executive Officer and other Named Executive Officers.
During 2021, Aon assisted the Compensation Committee as follows:

• | Analyzing and recommending the peer group;

• | Benchmarking compensation compared to peer companies and general industry data in order to assess base salary, annual incentive plan design and long-term incentive targets with that of peers and the competitive market;

• | Advising on the long-term incentive program and design;

• | Advising on the Chief Executive Officer’s compensation; and

• | Advising on director compensation.

• | Providing updates on executive compensation trends and talent retention strategies.

39

TABLE OF CONTENTS

In compliance with the disclosure requirements of the Securities and Exchange Commission and the Nasdaq regarding the independence of compensation consultants, the Compensation Committee assessed the independence of our independent compensation consultant and determined that the engagement of Aon does not raise any conflicts of interest.
Competitive Market Pay Information
Our compensation programs are designed to be competitive with companies of comparable size and industry with whom we compete for executive talent. The Compensation Committee works with Aon each year to identify a peer group that can provide information on competitive market compensation data, including related to salary, annual incentives and long-term incentives. The Compensation Committee uses the market compensation data as one of several reference points for determining the form and amount of compensation. To determine actual compensation amounts, the Compensation Committee uses its discretion and considers other factors, in addition to the peer group and competitive market data, such as the responsibilities, performance, contributions and experience of each NEO.
The peer group for Adverum was developed using specific selection criteria to identify companies that are comparable in size, have similar business economics, and may be a potential source or destination of our executive talent. Specific criteria included:

• | U.S. based and publicly-traded;

• | industry profile;

• | market capitalization generally 0.3x to 3.0x of Adverum;

• | employee headcount;

• | geographic location; and

• | availability of publicly disclosed information.

In October 2020, the Compensation Committee approved a compensation peer group that consisted of companies working in the gene cell therapy, ophthalmology and rare diseases space. The Compensation Committee placed special emphasis on the public pre-commercial biopharma companies in mid- to late-stage clinical trials with market capitalization ranging between $500 million and $4.0 billion. This peer group was used for purposes of making compensation decisions at the start of 2021 that set the base salaries, annual and long-term incentive opportunities for our executives. This peer group consisted of the following companies:

Apellis Pharmaceuticals | ​ | ​ | MeiraGTx
AVROBIO | ​ | ​ | Oyster Point Pharma
BridgeBio Pharma | ​ | ​ | Prevail Therapeutics
Constellation Pharmaceuticals | ​ | ​ | REGENXBIO
Corbus Pharmaceuticals | ​ | ​ | Rocket Pharmaceuticals
Dicerna Pharmaceuticals | ​ | ​ | Rubius Therapeutics
Editas Medicines | ​ | ​ | Sangamo Therapeutics
Epizyme | ​ | ​ | Syros Pharmaceuticals
Fate Therapeutics | ​ | ​ | Translate Bio
Homology Medicines | ​ | ​ | UniCure
Kodiak Sciences | ​ | ​ | Voyager Therapeutics

Adverum was positioned at the 56th percentile of the revised peer group in terms of market capitalization and the 34th percentile of the revised peer group in terms of the number of employees for the prior year.
In September 2021, following the SUSAR event and considering significant changes in our capitalization and strategic priorities, the Compensation Committee reviewed the peer group criteria and peer group composition to ensure the peer group comprised companies with market capitalization comparable to Adverum’s and ranging between $100 million and $1.2 billion. The priority was given to companies in later-stage clinical

trials to match Adverum’s Phase 2 trials for its lead product candidate, ADVM-022. Based on the revised criteria and the acquisition of several companies in the peer group, the Committee approved the following peer group that was used for various analysis through the rest of 2021. The same peer group was used to set executive compensation opportunities for 2022:

Aldeyra Therapeutics | ​ | ​ | Magenta Therapeutics
Applied Genetic Technologies | ​ | ​ | MeiraGTx
Assembly Biosciences | ​ | ​ | Mustang Bio
AVROBIO | ​ | ​ | Ovid Therapeutics
Calithera Biosciences | ​ | ​ | Oyster Point Pharma
Corbus Pharmaceuticals | ​ | ​ | Passage Bio
CytomX Therapeutics | ​ | ​ | RAPT Therapeutics
Epizyme | ​ | ​ | Solid Biosciences
Homology Medicine | ​ | ​ | Syros Pharmaceuticals
IVERIC bio | ​ | ​ | Voyager Therapeutics
Lineage Cell Therapeutics | ​ | ​ |

Adverum was positioned at the 30th percentile of the revised peer group in terms of market capitalization and the 88th percentile of the revised peer group in terms of the number of employees for the prior year.
Risk Assessment
The Compensation Committee monitors our executive and non-executive compensation programs to ensure that our compensation policies and practices are consistent with the long-term success of Adverum and do not create risks that are reasonably likely to have a material adverse effect on us. The risk oversight includes a review of pay mix, performance metrics and design of our short-and long-term incentive programs, focusing on the programs with variability of payout, the ability of a participant to directly affect payout and controls around participant action and payout. The Compensation Committee determined that none of the compensation programs encourage or create excessive risk-taking and are reasonably unlikely to have a material adverse effect on Adverum.
Elements of Adverum’s Executive Compensation Program
During 2021, the compensation program for the Named Executive Officers, consisted of base salary, short-term incentive compensation and long-term incentive compensation. The chart below outlines each element of the executive compensation program, the objectives of each component, and key features that may be used in determining each component.

Pay Component | ​ | ​ | Form of Compensation | ​ | ​ | Purpose and Key Features
Base Salary | ​ | ​ | • A fixed payment that reflects each executive’s scope of responsibilities, skills and experience • Delivered in cash | ​ | ​ | • Provides competitive fixed annual pay to attract and retain executives • Reflects market pay rates and individual performance
Annual Cash Incentives | ​ | ​ | • Short-term, at-risk variable compensation • Delivered in cash | ​ | ​ | • Focus on the achievement of annual corporate operating plan objectives aligned with the long-term strategic objectives (100% weighting of the total annual incentive opportunity for the CEO and 75% for other NEOs) • Incentivizes progress toward individual performance objectives tied to each NEO’s area of responsibility (25% weighting)
Equity Awards | ​ | ​ | • Long-term, at-risk compensation • Delivered in the form of stock options and performance stock units | ​ | ​ | • Aligns executives with the long-term interests of stockholders • Supports retention • Recognizes executive’s recent performance and potential future contributions

Executive officers are eligible to participate in benefit programs available to the broader employee population.
A description of each component of compensation for the Named Executive Officers in 2021 is below, including a discussion of the factors considered in determining the applicable amount payable or achievable under each component.
Determination of Executive Officer Compensation
Base Salary
Base salaries are set to attract and retain executive talent. The determination of any particular executive’s base salary considers individual performance and contribution, experience in the role, market rates of pay for comparable roles and internal equity. Each year, our Chief Executive Officer proposes base salary adjustments, if any, for all Named Executive Officers, excluding himself, based on performance, changes in responsibilities, market data and other relevant factors. His proposal is subject to review by the Compensation Committee, which may accept the recommendations or make modifications to the proposal as it deems appropriate. Adjustments to the Chief Executive Officer’s salary are initiated and approved by the Compensation Committee.
Salary increases are discretionary, and during 2021 the Chief Executive Officer recommended salary adjustments designed to align our pay program with the market pay levels for comparable executive roles. The actual base salary earned by the NEOs in 2021 is reported in the Salary column of the Summary Compensation Table.

(1) | Dr. D’Souza, Mr. DeRespino and Dr. Riley were not employed by Adverum in 2020. Mr. Thrift provided services of an interim Chief Financial Officer as an outside consultant and was never employed by Adverum.

(2) | At the beginning of 2021, Mr. Soparkar base salary was $415,030. In June 2021, in connection with his appointment to Chief Operating Officer and in recognition of his expanded scope of responsibilities, his base salary was increased to $455,000.

(3) | Effective January 2021, in connection with her promotion to Vice President, Clinical Development, Dr. Clark’s base salary was set at $380,140. In June 2021, following Dr. Clark’s appointment to Chief Medical Officer, her base salary was increased to $430,000.

Annual Cash Incentives
Pursuant to our annual cash incentive program, our Named Executive Officers are eligible to receive performance-based cash incentives based on the achievement of certain pre-established performance objectives that include corporate and individual performance goals. The annual incentive for our Chief Executive Officer is based exclusively on the corporate metrics, without an individual performance component. For other Named Executive Officers, the corporate and individual objectives are generally assigned a 75% and 25% weighting respectively.

(1) | Mr. Thrift was an outside consultant and was not eligible to participate in the 2021 annual incentive program.

In the first quarter of 2021, the Compensation Committee set 2021 performance metrics and their weightings, performance targets and stretch goals as described below. Given our focus on nonclinical trials, the annual incentive program encompassed several operational goals related to the key milestones of our gene therapy commercialization efforts. Due to the extraordinary circumstances triggered by the SUSAR event experienced in INFINITY clinical trial in April 2021, the performance goals set for the annual incentive program at the start of the year were no longer relevant to incentivize desired performance outcomes necessary to drive our clinical development strategy.
In July 2021, following adoption of a revised ADVM-022 development plan that focused exclusively on wet AMD, the Compensation Committee approved the operational and strategic milestones for the second half of the year covering the performance period from July 2021 through December 2021. The milestones aligned with our new post-SUSAR strategy to incentivize the executive team’s progress toward restoring our clinical trials process and expansion of pipeline and science supporting gene therapies. The specific milestones are proprietary and are not disclosed due to their competitive sensitivity.

Performance Goals | ​ | ​ | 1st Half Performance Period Weightings | ​ | ​ | 2nd Half Performance Period Weightings
Achieve clinical and regulatory milestones for ADVM-022 | ​ | ​ | 40% | ​ | ​ | 30%
Advance CMC to ensure ADVM-022 commercial readiness | ​ | ​ | 30% | ​ | ​ | 30%
Expand pipeline and extend lead in science supporting gene therapy | ​ | ​ | 10% | ​ | ​ | 25%
Drive Employee engagement and advance operational effectiveness | ​ | ​ | 10% | ​ | ​ | 10%
Maintain financial strength to achieve corporate objectives | ​ | ​ | 10% | ​ | ​ | 5%

At the end of the year, the Compensation Committee assessed the achievement of our corporate performance goals during the first and second half of the performance period against corresponding performance goals. Based on the results achieved, the Committee recognized corporate achievement for our NEOs at 80% of target for the full year.
In evaluating the NEOs’ success against the two sets of corporate goals, the Compensation Committee considered and assessed the impact of the SUSAR event, which was an extraordinary event that could not have been foreseen by the executive team, and the subsequent voluntary attrition in the context of a challenging talent market environment among the caliber of talent needed to restore our clinical development plan. With the progress achieved in advancing our clinical development program in wet AMD, developing our broader gene therapies pipeline including a new investigational gene therapy in blue cone monochromacy, effective cost

management as well as building core capabilities to transition from a single indication to an ocular gene therapy platform company the Compensation Committee determined that the NEOs demonstrated remarkable commitment and leadership navigating through the critical post-SUSAR period that set a strong foundation for rebuilding our clinical development strategy.

(3) | At the time of payout, Messrs. DeRespino and Leung, Mses. Patterson and Thedinga, and Dr. Clark each had resigned their positions within Adverum and were no longer eligible for the 2021 annual incentive program.

Long-Term Incentives
The Compensation Committee uses long-term incentives to create alignment of the Named Executive Officers’ interests with those of our stockholders and to foster a culture of ownership that incentivizes our executives to deliver sustained long-term value growth. The long-term incentive awards for the Named Executive Officers are recommended by the Chief Executive Officer and approved by the Compensation Committee. The long-term incentive award for the Chief Executive Officer is initiated and approved directly by the Compensation Committee.
We offer stock options to purchase shares of our common stock as a long-term component of our compensation program. We typically grant stock options to employees when they commence employment with us and may subsequently grant additional stock options or stock unit awards at the discretion of our Compensation Committee or our Board. Our stock options allow employees to purchase shares of our common stock at a price equal to the fair market value of our common stock on the date of grant.
Generally, our stock options vest over a four-year period, with 25% vesting on the first anniversary of the grant date and 1/48th of the total shares per month thereafter. From time to time, equity awards may be awarded using alternate vesting schedules as set by the Compensation Committee or our Board.
2021 Long-Term Equity Incentives
In February 2021, we granted the below Named Executive Officers long-term equity awards that were delivered in the form of stock options that vest over a four-year term as described above.

Name of Executive Officer(1)(2) | ​ | ​ | 2021 Stock Options (#)

2021 Special Performance Incentive Awards
In August 2021, the Compensation Committee approved the grant of a special performance-based awards with a goal to support stability of the executive team and to incentivize accelerated achievement of the post-SUSAR recovery strategy.
In determining the appropriateness of granting the special awards, the Compensation Committee considered the value of the Named Executive Officers’ previously granted long-term incentive opportunities, the time-horizon of the post-SUSAR recovery efforts, the value expected to be generated for stockholders upon success of the strategy and the impact of the awards on our share pool. The awards were issued in a mix of performance stock units (“PSUs”) and stock options.

TABLE OF CONTENTS

• | 1∕3 of the shares will vest upon dosing of the first subject in a potentially registrational clinical trial of ADVM-022 or another product candidate owned or being developed by Adverum in wet age-related macular degeneration or another indication determined by the Compensation Committee to represent a significant unmet medical need, which dosing or other indication occurs on or prior to the third anniversary of the date of grant; and

• | 1∕3 of the shares will vest upon consummation of a strategic corporate transaction, not constituting a change in control, that is determined by the Compensation Committee to be transformative for Adverum, which consummation occurs prior on or prior to the third anniversary of the date of grant, in each case contingent upon certification by the Compensation Committee of the achievement of such milestone and subject to the executive’s continued service on each such vesting date. Non-exclusive examples of a strategic corporate transaction are (i) a collaboration with another company for the development and commercialization of a major asset, (ii) a substantial royalty-based or other structured financing, and (iii) the acquisition or in-license of a significant asset for development and commercialization.

However, the vesting milestones provide for an earlier distribution in the case of early achievement of certain goals. Specifically, if the vesting milestone for any tranche is achieved (a) within twelve (12) months after the date of grant, 50% of that tranche will vest on the date of certification and the other 50% will vest on the first anniversary of such date; or (b) more than twelve (12) but less than twenty-four (24) months after the date of grant, 50% of that tranche will vest on the date of certification and the other 50% will vest on the six (6)-month anniversary of such date. In either case, the second 50% tranche shall be deemed “Second Tranche PSUs.”

• | Change in Control: Upon a Change in Control, the performance vesting conditions will no longer be applicable, and all unvested PSUs will automatically convert into time-based PSUs that vest on the first anniversary of the Change in Control, subject to Participant’s continued service through such date. Notwithstanding the foregoing, if Participant’s service is terminated prior to such anniversary in a Covered Termination giving rise to equity award acceleration under Participant’s Change in Control and Severance Agreement (the “CIC Agreement”), all unvested PSUs will accelerate upon such termination. “Covered Termination” shall have the meaning set forth in the CIC Agreement.

• | Non-CIC-related termination of service: If Participant’s service is terminated in a manner that is a Covered Termination but that does not give rise to equity award acceleration under Participant’s CIC Agreement, any then-unvested PSUs will be forfeited, provided that (i) any unvested Second Tranche PSUs shall vest as of the date of termination; and (ii) any other unvested PSUs will remain outstanding for ninety (90) days following such termination, and any PSU vesting milestone achieved and certified during such 90-day period shall be deemed to have been achieved at time of termination. If Participant’s service is terminated in a manner that is not a Covered Termination, all unvested PSUs shall be forfeited as of the date of such termination.

As of April 13, 2022, no portion of the PSUs had vested.

TABLE OF CONTENTS

Executive Severance Arrangements – Current Executive Officers
Our NEOs that are current executive officers are eligible to receive severance payments and benefits pursuant to change in control and severance agreements each entered into with us.
For purposes of the change in control and severance agreements, “Cause” is determined in the sole discretion of the Board and means misconduct, including: (i) the executive’s commission or the attempted commission of or participation in any crime involving fraud, dishonesty or moral turpitude that results in (or might have reasonably resulted in) material harm to our business; (ii) intentional and material damage to our property and/or misappropriation of our funds; (iii) conduct that constitutes gross insubordination, incompetence or habitual neglect of duties that results in (or might have reasonably resulted in) material harm to our business that has not been cured within 30 days after written notice from the executive’s immediate supervisor or in the case of the chief executive officer, from the Board; or (iv) material breach of the Proprietary Information Agreement executed by the executive.
For purposes of the change in control and severance agreements, “Constructive Termination” means any of the following actions taken without Cause by us or a successor corporation or entity without the executive’s consent: (i) substantial reduction of the executive’s rate of compensation; (ii) material reduction in the executive’s duties, provided, however, that a change in job position (including a change in title) shall not be deemed a “material reduction” unless the executive’s new duties are substantially reduced from the prior duties; (iii) failure or refusal of a successor to Adverum to assume our obligations under the agreement in the event of a change in control; (iv) relocation of the executive’s principal place of employment or service to a place greater than 50 miles from the executive’s then current principal place of employment or service; (v) the requirement to increase the amount of time per week that the executive provides services to us or (vi) the requirement that the participant cease other employment or consulting engagements, unless such employment and/or consulting engagement results in a conflict with our business.
Laurent Fischer, M.D.
Pursuant to his change in control and severance agreement, in the event of a termination of employment by us without Cause or a Constructive Termination more than three months prior to a change in control or more than 12 months after a change in control, Dr. Fischer will be entitled to (i) 12 months of base salary and (ii) up to 12 months of continued healthcare coverage. In the event of a termination without Cause or a Constructive Termination, in each case, within the period commencing three months prior to a change in control and ending twelve months following a change in control, he will be entitled to (i) an amount equal to the sum of 24 months of base salary and two times Dr. Fischer’s target annual bonus for the year in which the termination occurs, payable in a lump sum, (ii) up to 24 months of continued healthcare coverage and (iii) the accelerated vesting of all of his outstanding equity awards. The payments and benefits described above are conditioned upon such executive executing and not revoking a release of claims against us and are subject to reduction in the event that such a reduction would result in a better after-tax outcome for Dr. Fischer.
Rupert D’Souza, Ph.D., Brigit Riley, Ph.D., and Kishor Peter Soparkar
Pursuant to their respective change in control and severance agreements, in the event of a termination of employment by us without Cause or Constructive Termination more than three months prior to a change in control or more than twelve months after a change in control, Drs. D’Souza, Riley and Mr. Soparkar will be entitled to (i) nine months of base salary and (i) up to nine months of continued healthcare coverage.
In the event Drs. D’Souza, Riley or Mr. Soparkar are terminated by us without Cause or experiences a Constructive Termination, in each case, within the period commencing three months prior to a change in control and ending on the first anniversary of the change in control, then he or she will be entitled to (i) an amount equal to the sum of 12 months of base salary and the executive’s target annual bonus for the year in which the termination occurs, payable in a lump sum, (ii) up to 12 months of continued healthcare coverage, and (iii) the accelerated vesting of all outstanding equity awards.

Other Benefits
The general employment benefits provided to the NEOs are generally the same as those provided to other nonunion, salaried employees and include medical, dental, basic life insurance, short and long-term disability insurance, and a tax-qualified 401(k) plan.
Employee 401(k) Plan
U.S. full-time employees qualify for participation in our 401(k) plan, which is intended to qualify as a tax-qualified defined contribution plan under the Internal Revenue Code.
Pension Benefits
Other than with respect to our 401(k) plan, our U.S. employees, including our Named Executive Officers, do not participate in any plan that provides for retirement payments and benefits, or payments and benefits that will be provided primarily following retirement.
Nonqualified Deferred Compensation
During 2021, our U.S. employees, including our Named Executive Officers, did not contribute to, or earn any amounts with respect to, any defined contribution or other plan sponsored by us that provides for the deferral of compensation on a basis that is not tax-qualified.
Limited Trading Windows; No Hedging or Pledging Transactions
Generally, executive officers and directors can trade Adverum’s stock only when they do not have any material nonpublic information and there is not a trading blackout in place. In addition, executive officers are prohibited from engaging in hedging and pledging transactions.

TABLE OF CONTENTS

Tax and Accounting Considerations
Under ASC 718, we are required to estimate and record an expense for each award of equity compensation (including stock options, RSUs and PSUs) over the vesting period of the award. As long as stock options, RSUs and PSUs remain components of our long-term compensation program, we expect to record stock-based compensation expense on an ongoing basis according to ASC 718. Compensation expense relating to awards subject to performance conditions is recognized if it is probable that the performance goals will be achieved. The probability of achievement of such goals is assessed on a quarterly basis. The Compensation Committee has considered, and may in the future consider, the accounting implications of the granting of stock option grants, restricted stock units and/or performance stock unit awards.
Under Section 162(m) of the Internal Revenue Code (Section 162(m)), compensation paid to each of the company’s “covered employees” that exceeds $1 million per taxable year is generally non-deductible. Although the Compensation Committee will continue to consider tax implications as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for the NEOs in a manner consistent with the goals of the company’s executive compensation program and the best interests of the company and its stockholders, which may include providing for compensation that is not deductible by the company due to the deduction limit under Section 162(m).
Compensation Committee Report1
The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis (the “CD&A”) contained in this proxy statement. Based on this review and discussion, the Compensation Committee has recommended to the Board that the CD&A be included in this proxy statement and incorporated into our Annual Report on Form 10-K for the year ended December 31, 2021.

Each of Ms. Patterson, Mr. DeRespino, Mr. Thrift, Mr. Leung and Ms. Clark and Ms. Thedinga are not listed in the table as they were no longer at Adverum as of December 31, 2021, and therefore were not entitled to any severance benefits as a result of a change in control or termination of service as of December 31, 2021.

TABLE OF CONTENTS

(1) | “Change of Control Period” is defined as the period beginning three months prior to and ending twelve months after a Change in Control (as defined in the Change in Control and Severance Agreements).

(2) | Represents, (i) in the case of Dr Fischer, a lump sum equal to 24 months base salary and two times his target bonus, and (ii) in the cases of the other named executive officers, a lump sum equal to 12 months base salary.

(3) | Represents, (i) in the case of Dr Fischer, 24 months of COBRA premiums, and (ii) in the cases of the other named executive officers other than Dr. D’Souza, 12 months of COBRA premiums.

(4) | Represents accelerated vesting of 100% of outstanding equity awards held by the named executive officer. Per SEC rules, the value of accelerated stock options is the aggregate spread between $1.76, the closing price of our common stock on December 31, 2021, and the exercise prices of the accelerated stock options, if less than $1.76, and the value of accelerated RSU awards is calculated by multiplying the number of shares subject to acceleration by $1.76, the closing price of our common stock on the Nasdaq Global Market on December 31, 2021. No value is attributable to the accelerated stock options as the exercise price of the options was above the closing price of our common stock on December 31, 2021.

(5) | Represents, (i) in the case of Dr. Fischer, 12 months of base salary continuation, and (ii) in the cases of the other named executive officers, nine months of base salary continuation.

(6) | Represents, (i) in the case of Dr. Fischer, 12 months of COBRA premiums, and (ii) in the cases of the other named executive officers, nine months of COBRA premiums.

(7) | Dr. D’Souza was not yet eligible for our benefit plans as of December 31, 2021, and so no COBRA premiums would have been due to him pursuant to his change in control and severance agreement.

Pay Ratio Disclosure
We believe that we provide fair and equitable compensation to our employees through a combination of competitive base pay, incentives and other benefits. In accordance with Item 402(u) of Regulation S-K, promulgated by the Dodd Frank Act, we determined the ratio of: (a) the annual total compensation of our Chief Executive Officer; to (b) the median of the annual total compensation of all of our employees, except for our Chief Executive Officer, both calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K (CEO Pay Ratio).
To determine the median of the annual total compensation of all of our employees, except for our Chief Executive Officer, we used the following methodology:
To identify our employee population, we used tax and payroll records to determine all full-time and part-time employees, excluding our Chief Executive Officer, who were employed as of December 31, 2021.
To identify the median employee with respect to annual total compensation of all of our employees, we calculated each employee’s “total direct compensation,” which consists of: (i) 2021 base salary (using a reasonable estimate of the hours worked and overtime actually paid during 2021 for hourly employees); (ii) cash bonus for 2021; (iii) the grant date fair value of any equity awards granted during 2021 (using the same methodology that we use for estimating the value of the equity awards granted to our Named Executive Officers and reported in our Summary Compensation Table), and (iv) all other compensation (calculated for reporting as set forth in the Summary Compensation Table).
In making this determination, we annualized the base salary and target cash bonus for all full-time and part-time employees who were employed by us for less than the entirety of 2021.
Once our representative median employee was identified in the manner described above, we calculated the annual total compensation of the representative median employee using the same methodology that we used to determine the annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table included in this Proxy Statement. For 2021, the median of the annual total compensation of our employees (other than our Chief Executive Officer) was $188,229 and the annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table included in this Proxy Statement, was $8,996,489. Based on this information, our CEO Pay Ratio for 2021 was 48 to 1.
This CEO Pay Ratio represents our reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K and applicable guidance, which provide significant flexibility in how companies identify the median employee. Each company may use a different methodology and make different assumptions particular to that company. As a result, and as explained by the SEC when it adopted these rules, in considering this CEO Pay Ratio disclosure, stockholders should keep in mind that the rule was not designed to facilitate comparisons of CEO Pay Ratios among different companies, even companies within the same industry, but rather to allow stockholders to better understand and assess each particular company’s compensation practices and CEO Pay Ratio disclosures. Neither the Compensation Committee nor our management used our CEO Pay Ratio for 2021 in making compensation decisions.

(1) | Includes the Amended and Restated 2006 Equity Incentive Plan, 2014 Plan and the 2014 Employee Stock Purchase Plan (the “ESPP”).

(2) | The 2014 Plan contains an “evergreen” provision, pursuant to which the number of shares of common stock reserved for issuance or transfer pursuant to awards under the 2014 Plan shall be increased on the first day of each year beginning in 2015 and ending in 2024, equal to the lesser of (A) 4.0% of the shares of stock outstanding (on an as converted basis) on the last day of the immediately preceding fiscal year and (B) such smaller number of shares of stock as determined by our Board; provided, however, that no more than 10,441,663 shares of stock may be issued upon the exercise of incentive stock options.

(3) | Excludes shares subject to rights outstanding under the ESPP as the number of shares issuable pursuant to these rights cannot be determined as of December 31, 2021, as it depends on amounts contributed by the holder of the rights and the price of a share of our common stock on the last day of the purchase period.

(4) | Includes options pursuant to the inducement grant exception under Nasdaq Listing Rule 5635(c)(4) as an inducement that was material to their employment with us. Ms. Patterson’s option was for 200,000 shares and had a vesting commencement date of June 15, 2016. The option is fully vested. Also includes the 2017 Inducement Plan adopted by the Board in October 2017. The 2017 Inducement Plan provides for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other forms of equity compensation (collectively, stock awards), all of which may be granted to persons not previously our employees or directors, or following a bona fide period of non-employment, as an inducement material to the individuals’ entering into employment with us within the meaning of Nasdaq Listing Rule 5635(c)(4). The 2017 Inducement Plan has a share reserve covering 6,100,000 shares of our common stock. If a stock award granted under the 2017 Inducement Plan expires or otherwise terminates without all of the shares covered by the stock award having been issued, or is settled in cash, or shares are withheld to satisfy tax withholding obligations, then the shares of our common stock not acquired or withheld pursuant to the stock award again will become available for subsequent issuance under the 2017 Inducement Plan.

DELINQUENT SECTION 16(A) REPORTS
Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.
To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the year ended December 31, 2021, all Section 16(a) filing requirements applicable to our officers, directors and greater than 10% beneficial owners were complied with, except that Brigit Riley, Ph.D., our Chief Scientific Officer, filed one Form 3 reporting initial beneficial ownership late due to a delay in obtaining a Central Index Key from the SEC.
HOUSEHOLDING
The SEC has adopted rules known as “householding” that permit companies and intermediaries (such as brokers) to deliver one set of proxy materials to multiple stockholders residing at the same address. This process enables us to reduce our printing and distribution costs, and reduce our environmental impact. Householding is available to both registered stockholders and beneficial owners of shares held in street name.
Registered Stockholders
If you are a registered stockholder and have consented to householding, then we will deliver or mail one set of our proxy materials, as applicable, for all registered stockholders residing at the same address. Your consent will continue unless you revoke it, which you may do at any time by providing notice to our Corporate Secretary by telephone at (650) 656-9323 or by mail at 100 Cardinal Way, Redwood City, California 94063. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the annual report or proxy statement to a stockholder at a shared address to which a single copy of the documents was delivered.
If you are a registered stockholder who has not consented to householding, then we will continue to deliver or mail copies of our proxy materials, as applicable, to each registered stockholder residing at the same address. You may elect to participate in householding and receive only one set of proxy materials for all registered stockholders residing at the same address by providing notice to Adverum as described above.
Street Name Holders
Stockholders who hold their shares through a brokerage may elect to participate in householding, or revoke their consent to participate in householding, by contacting their respective brokers.
ANNUAL REPORT
This proxy statement is accompanied by our 2021 Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the year ended December 31, 2021 (the “Form 10-K”). The Form 10-K includes our audited financial statements. We have filed the Form 10-K with the SEC, and it is available free of charge at the SEC’s website at www.sec.gov and on our website at http://investors.adverum.com. In addition, upon written request to our Corporate Secretary at 100 Cardinal Way, Redwood City, California 94063, we will mail a paper copy of our Form 10-K, including the financial statements and the financial statement schedules, to you free of charge.

For purposes of the Plan, the employment relationship shall be treated as continuing intact while the individual is on military leave, sick leave or other leave of absence approved by the Company or Designated Subsidiary and meeting the requirements of Treasury Regulation Section 1.421-1(h)(2). Where the period of leave exceeds three (3) months, or such other period specified in Treasury Regulation Section 1.421-1(h)(2), and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship shall be deemed to have terminated on the first day immediately following such three (3)-month period, or such other period specified in Treasury Regulation Section 1.421-1(h)(2).

(b)If the Common Stock is not listed on an established securities exchange, national market system or automated quotation system, but the Common Stock is regularly quoted by a recognized securities dealer, its Fair Market Value shall be the mean of the high bid and low asked prices for such date or, if there are no high bid and low asked prices for a share of Common Stock on such date, the high bid and low asked prices for a share of Common Stock on the last preceding date for which such information exists, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or

PARTICIPATION
3.1 Eligibility.
(a)Any Eligible Employee who shall be employed by the Company or a Designated Subsidiary on a given Enrollment Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of Articles IV and V hereof, and the limitations imposed by Section 423(b) of the Code and the Treasury Regulations thereunder.
(b)No Eligible Employee shall be granted an Option under the Plan which permits the Participant’s rights to purchase shares of Common Stock under the Plan, and to purchase stock under all other employee stock purchase plans of the Company, any Parent or any Subsidiary subject to the Section 423 of the Code (any such Option or other option, a “Section 423 Option”), to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined at the time the Section 423 Option is granted) for each calendar year in which any Section 423 Option granted to the Participant is outstanding at any time. For purposes of the limitation imposed by this subsection,
(i)the right to purchase stock under a Section 423 Option accrues when the Section 423 Option (or any portion thereof) first becomes exercisable during the calendar year,
(ii)the right to purchase stock under a Section 423 Option accrues at the rate provided in the Section 423 Option, but in no case may such rate exceed $25,000 of fair market value of such stock (determined at the time such option is granted) for any one calendar year, and (iii) a right to purchase

TABLE OF CONTENTS

stock which has accrued under a Section 423 Option may not be carried over to any other Section 423 Option; provided that Participants may carry forward amounts so accrued that represent a fractional share of stock and were withheld but not applied towards the purchase of Common Stock under an earlier Offering Period, and may apply such amounts towards the purchase of additional shares of Common Stock under a subsequent Offering Period.
The limitation under this Section 3.1(b) shall be applied in accordance with Section 423(b)(8) of the Code and the Treasury Regulations thereunder.
3.2 Election to Participate; Payroll Deductions.
(a)Except as provided in Section 3.3 hereof, an Eligible Employee may become a Participant in the Plan only by means of payroll deduction. Each individual who is an Eligible Employee as of an Offering Period’s Enrollment Date may elect to participate in such Offering Period and the Plan by delivering to the Company a payroll deduction authorization no later such period of time prior to the applicable Enrollment Date as determined by the Administrator, in its sole discretion.
(b)Subject to Section 3.1(b) hereof, payroll deductions (i) shall be equal to at least one percent (1%) of the Participant’s Compensation as of each Payday of the Offering Period following the Enrollment Date, but not more than the lesser of fifteen percent (15%) of the Participant’s Compensation as of each Payday of the Offering Period following the Enrollment Date or $25,000 per Offering Period; and (ii) may be expressed either as (A) a whole number percentage, or (B) a fixed dollar amount. Amounts deducted from a Participant’s Compensation with respect to an Offering Period pursuant to this Section 3.2 shall be deducted each Payday through payroll deduction and credited to the Participant’s Plan Account.
(c)Following at least one (1) payroll deduction, a Participant may decrease (to as low as zero) the amount deducted from such Participant’s Compensation only once during an Offering Period upon ten (10) calendar days’ prior written notice to the Company. A Participant may not increase the amount deducted from such Participant’s Compensation during an Offering Period.
(d)Notwithstanding the foregoing, upon the termination of an Offering Period, each Participant in such Offering Period shall automatically participate in the immediately following Offering Period at the same payroll deduction percentage or fixed amount as in effect at the termination of the prior Offering Period, unless such Participant delivers to the Company a different election with respect to the successive Offering Period in accordance with Section 3.1(a) hereof, or unless such Participant becomes ineligible for participation in the Plan.
3.3 Leave of Absence. During leaves of absence approved by the Company meeting the requirements of Treasury Regulation Section 1.421-1(h)(2) under the Code, a Participant may continue participation in the Plan by making cash payments to the Company on his or her normal payday equal to his or her authorized payroll deduction.
ARTICLE IV
PURCHASE OF SHARES
4.1 Grant of Option. Each Participant shall be granted an Option with respect to an Offering Period on the applicable Grant Date. Subject to the limitations of Section 3.1(b) hereof, the number of shares of Common Stock subject to a Participant’s Option shall be determined by dividing (a) such Participant’s payroll deductions accumulated prior to such Exercise Date and retained in the Participant’s Plan Account on such Exercise Date by (b) the applicable Option Price; provided that in no event shall a Participant be permitted to purchase during each Offering Period more than 6,000 shares of Common Stock (subject to any adjustment pursuant to Section 5.2 hereof). The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that a Participant may purchase during such future Offering Periods. Each Option shall expire on the Exercise Date for the applicable Offering Period immediately after the automatic exercise of the Option in accordance with Section 4.3 hereof, unless such Option terminates earlier in accordance with Article 6 hereof.
4.2 Option Price. The “Option Price” per share of Common Stock to be paid by a Participant upon exercise of the Participant’s Option on the applicable Exercise Date for an Offering Period shall be equal to eighty five percent (85%) of the lesser of the Fair Market Value of a share of Common Stock on (a) the
A-4

TABLE OF CONTENTS

applicable Grant Date and (b) the applicable Exercise Date; provided that in no event shall the Option Price per share of Common Stock be less than the par value per share of the Common Stock.
4.3 Purchase of Shares.
(a)On the applicable Exercise Date for an Offering Period, each Participant shall automatically and without any action on such Participant’s part be deemed to have exercised his or her Option to purchase at the applicable per share Option Price the largest number of whole shares of Common Stock which can be purchased with the amount in the Participant’s Plan Account. Any balance less than the per share Option Price that is remaining in the Participant’s Plan Account (after exercise of such Participant’s Option) as of the Exercise Date shall be carried forward to the next Offering Period, unless the Participant has elected to withdraw from the Plan pursuant to Section 6.1 hereof or, pursuant to Section 6.2 hereof, such Participant has ceased to be an Eligible Employee. Any balance not carried forward to the next Offering Period in accordance with the prior sentence promptly shall be refunded to the applicable Participant. For the avoidance of doubt, in no event shall an amount greater than or equal to the per share Option Price as of an Exercise Date be carried forward to the next Offering Period.
(b)As soon as practicable following the applicable Exercise Date, the number of shares of Common Stock purchased by such Participant pursuant to Section 4.3(a) hereof shall be delivered (either in share certificate or book entry form), in the Company’s sole discretion, to either (i) the Participant or (ii) an account established in the Participant’s name at a stock brokerage or other financial services firm designated by the Company. If the Company is required to obtain from any commission or agency authority to issue any such shares of Common Stock, the Company shall seek to obtain such authority. Inability of the Company to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance of any such shares shall relieve the Company from liability to any Participant except to refund to the Participant such Participant’s Plan Account balance, without interest thereon.
4.4 Transferability of Rights.
(a)An Option granted under the Plan shall not be transferable, other than by will or the applicable laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant. No option or interest or right to the Option shall be available to pay off any debts, contracts or engagements of the Participant or his or her successors in interest or shall be subject to disposition by pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempt at disposition of the option shall have no effect.
ARTICLE V
PROVISIONS RELATING TO COMMON STOCK
5.1 Common Stock Reserved. Subject to adjustment as provided in Section 5.2 hereof, the maximum number of shares of Common Stock that shall be made available for sale under the Plan shall be 8,800,000. Shares of Common Stock made available for sale under the Plan may be authorized but unissued shares, treasury shares of Common Stock, or reacquired shares reserved for issuance under the Plan.
5.2 Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, Merger or Asset Sale.
(a)Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock which have been authorized for issuance under the Plan but not yet placed under Option, as well as the price per share and the number of shares of Common Stock covered by each Option under the Plan which has not yet been exercised shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities
A-5

TABLE OF CONTENTS

convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.
(b)Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Administrator shall notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof.
(c)Merger or Asset Sale. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent Option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Option, any Offering Periods then in progress shall be shortened by setting a New Exercise Date and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date of the Company’s proposed sale or merger. The Administrator shall notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof.
5.3 Insufficient Shares. If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which Options are to be exercised may exceed the number of shares of Common Stock remaining available for sale under the Plan on such Exercise Date, the Administrator shall make a pro rata allocation of the shares of Common Stock available for issuance on such Exercise Date in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising Options to purchase Common Stock on such Exercise Date, and unless additional shares are authorized for issuance under the Plan, no further Offering Periods shall take place and the Plan shall terminate pursuant to Section 7.5 hereof. If an Offering Period is so terminated, then the balance of the amount credited to the Participant’s Plan Account which has not been applied to the purchase of shares of Common Stock shall be paid to such Participant in one lump sum in cash within thirty (30) days after such Exercise Date, without any interest thereon.
5.4 Rights as Stockholders. With respect to shares of Common Stock subject to an Option, a Participant shall not be deemed to be a stockholder of the Company and shall not have any of the rights or privileges of a stockholder. A Participant shall have the rights and privileges of a stockholder of the Company when, but not until, shares of Common Stock have been deposited in the designated brokerage account following exercise of his or her Option.
ARTICLE VI
TERMINATION OF PARTICIPATION
6.1 Cessation of Contributions; Voluntary Withdrawal.
(a)A Participant may cease payroll deductions during an Offering Period and elect to withdraw from the Plan by delivering written notice of such election to the Company in such form and at such time prior to the Exercise Date for such Offering Period as may be established by the Administrator (a “Withdrawal Election”). A Participant electing to withdraw from the Plan may elect to either (i) withdraw all of the funds then credited to the Participant’s Plan Account as of the date on which the Withdrawal Election is received by the Company, in which case amounts credited to such Plan Account shall be returned to the Participant in one (1) lump-sum payment in cash within thirty (30) days after such election is received by the Company, without any interest thereon, and the Participant shall cease to participate in the Plan and the Participant’s Option for such Offering Period shall terminate; or (ii) exercise the Option for the maximum number of whole shares of Common Stock on the applicable Exercise Date with any remaining Plan

7.5 Amendment and Termination of the Plan.
(a)The Board may, in its sole discretion, amend, suspend or terminate the Plan at any time and from time to time; provided, however, that without approval of the Company’s stockholders given within twelve (12) months before or after action by the Board, the Plan may not be amended to increase the maximum number of shares of Common Stock subject to the Plan or change the designation or class of Eligible Employees; and provided, further that without approval of the Company’s stockholders, the Plan may not be amended in any manner that would cause the Plan to no longer be an “employee stock purchase plan” within the meaning of Section 423(b) of the Code.
(b)In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, to the extent permitted under Section 423 of the Code, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:

7.9 Conformity to Securities Laws.

(a)Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates or make any book entries evidencing shares of Common Stock pursuant to the exercise of an Option by a Participant, unless and until the Board or the Committee has determined, with advice of counsel, that the issuance of such shares of Common Stock is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any securities exchange or automated quotation system on which the shares of Common Stock are listed or traded, and the shares of Common Stock are covered by an effective registration statement or applicable exemption from registration.
