2009, the FASB issued updated revenue recognition guidance under ASC Topic 605 relating to revenue arrangements with multiple deliverables. Under the revised guidance, companies with revenue arrangements that have multiple deliverables must assess
whether or not multiple deliverables exist under the revised guidance, how the deliverables should be separated and how the consideration should be allocated to the elements. In addition, the revised guidance requires an entity to allocate revenue
in an arrangement using the best estimated selling price, or BESP, of deliverables if a vendor does not have vendor specific objective evidence of selling price or third-party evidence, or TPE, of selling price. Each unit must have stand-alone value
to the customer, similar to previous guidance. Effective January&nbsp;1, 2011, the Company adopted the revised guidance for revenue recognition in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification,
or ASC, Topic 605-25, &#147;Revenue Recognition - Arrangements with Multiple Deliverables,&#148; on a prospective basis for applicable transactions originating or materially modified after December&nbsp;31, 2010. This guidance does not change the
units of accounting for the Company&#146;s revenue transactions. The adoption of this revised guidance did not have a material impact on the Company&#146;s results of operations for the three-month period ended March&nbsp;31, 2011 nor is it
currently anticipated to have a material impact on future periods. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:8%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Revenue is recognized when (i)&nbsp;persuasive evidence of

according to the provisions of the purchase order or sales contract. For revenue arrangements with multiple elements, the Company evaluates whether the delivered elements have stand-alone value to the customer, whether the value of the undelivered
elements is reliably determinable under the guidance of the Accounting Standards Update, or ASU, No.&nbsp;2009-13, and whether the delivery of the remaining elements is probable and within the Company&#146;s control. When all of these conditions are
met, the Company recognizes the revenue on the delivered elements. If these conditions are not met, the Company defers revenue until such time as all of the conditions have been met or all of the elements have been delivered. Prior to adoption of
ASU No.&nbsp;2009-13, consideration received was allocated to elements that were identified as discrete units of accounting based on the relative fair value method. Beginning January&nbsp;1, 2011, consideration received is allocated to elements that
are identified as discrete units of accounting based on the best estimated selling price as consistent vendor specific objective evidence of selling price, or VSOE, is not discernable. We have determined that VSOE is not discernable due to our
limited history of selling our products and variability in our pricing. Since the Company&#146;s products are novel and unique and are not sold by others, third-party evidence of selling price is unavailable. </FONT></P>

frequently if events or changes in circumstances indicate that they may be impaired. The Company evaluates goodwill on an annual basis as of the end of the third quarter of each fiscal year. The test for goodwill impairment is a two-step process.
The first step compares the fair value of each reporting unit with its respective carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired
and, therefore, the second step of the impairment test is unnecessary. The second step, used to measure the amount of impairment loss, compares the implied fair value of each reporting unit&#146;s goodwill with the respective carrying amount of that
goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Management has determined that it operates as a single reporting
unit and therefore evaluates goodwill impairment at the enterprise level. There were no impairment charges during the three months ended March&nbsp;31, 2011. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:8%"><FONT

commercialization rights to the Company in February 2006, Baxter International Inc., or Baxter, agreed to supply, at the Company&#146;s expense, certain transition services, including regulatory, technical and related administrative support through
December&nbsp;31, 2006. During that 2006 transition period, the Company recorded receivables of $2.8 million from Baxter and payables of $4.7 million to Baxter, associated with those transition services. The Company and Baxter had disputed the
amounts owed, although the Company recorded the transition service receivables and payables on its condensed consolidated balance sheets. In December 2009, the Company and Baxter entered into a settlement agreement with both parties waiving all
rights and obligations associated with the 2006 transition services. In consideration for agreeing to the settlement, the Company agreed to pay Baxter $0.5 million which was recorded as a payable on its December&nbsp;31, 2009 consolidated balance
sheet. The $0.5 million payable was paid by the Company in 2010. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:8%"><FONT STYLE="font-family:Times New Roman" SIZE="2">As a result of Baxter&#146;s sale of its transfusion

platelet system, 3% for the plasma system, 5% for the red blood cell system, and 6.5% on sales of UVA illuminators. During the three months ended March&nbsp;31, 2011, and March&nbsp;31, 2010, the Company made royalty payments to Fenwal of $0.5
million and $0.4 million, respectively. At March&nbsp;31, 2011 and December&nbsp;31, 2010, the Company owed royalties to Fenwal of $0.6 million and $0.5 million, respectively. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:8%"><FONT

agreement, the Company pays Fenwal a set price per kit, which is established annually plus a fixed surcharge per kit. In addition, volume driven manufacturing overhead is to be paid or refunded if actual manufacturing volumes are lower or higher
than the annually estimated production volumes. The Company made payments to Fenwal of $2.2 million and $3.4 million, relating to the manufacturing of the Company products during the three months ended March&nbsp;31, 2011 and March&nbsp;31, 2010,
respectively. At March&nbsp;31, 2011 and December&nbsp;31, 2010, the Company owed Fenwal $4.1 million and $2.3 million, respectively, for INTERCEPT disposable kits manufactured. The Company had a receivable due from Fenwal of $0.03 million and $0.2

States Armed Forces. This funding supports advanced development of the Company&#146;s red blood cell system. The Company recognized $0.4 million and $0.2 million of revenue under these agreements during the three months ended March&nbsp;31, 2011 and

and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking
statements. Examples of forward-looking statements include, but are not limited to, statements about our estimates regarding the sufficiency of our cash resources, our ability to commercialize and achieve market acceptance of the INTERCEPT Blood
Systems, the anticipated progress of our research, development and clinical programs, our ability to manage cost increases associated with pre-clinical and clinical development for the INTERCEPT Blood Systems, our ability to obtain and maintain
regulatory approvals of the INTERCEPT Blood Systems, the ability of our products to inactivate pathogens that may emerge in the future, and our ability to protect our intellectual property and operate our business without infringing upon the

similar expressions intended to identify such forward-looking statements. Forward-looking statements reflect our current views with respect to future events, are based on assumptions, and are subject to risks and uncertainties. There can be no
assurance that these statements will prove to be correct. Certain important factors could cause actual results to differ materially from those discussed in such statements, market acceptance of our products, whether our preclinical and clinical data
or data from commercial use will be considered sufficient by regulatory authorities to grant marketing approval for our products, our limited experience in sales, marketing and regulatory support for the INTERCEPT Blood System, the complexity of our
supply chain and our reliance on suppliers, incompatibility of our platelet system with some commercial platelet collection methods, our need to complete certain of our product components&#146; commercial design, more effective product offerings by,

inception in 1991, we have devoted substantially all of our efforts and resources to the research, development, clinical testing and commercialization of blood safety systems and, from 2001 until late 2007, immunotherapies for cancer and infectious
disease. Our INTERCEPT platelet system, or the &#147;platelet system,&#148; and our INTERCEPT plasma system, or the &#147;plasma system,&#148; have received CE marks and are being marketed in a number of countries in Europe, The Commonwealth of
Independent States, or CIS, and the Middle East and selected countries in other regions around the world. In addition, we plan to continue development of our INTERCEPT red blood cell system. Subject to the availability of adequate funding from

competitive developments and regulatory factors. Until we are able to generate a sufficient amount of product revenue and generate positive net cash flows from operations, meeting our long-term
capital requirements is in large part subject to access to public and private equity and debt capital markets, as well as to additional collaborative arrangements with partners or government grants, augmented by cash generated from operations and
interest income earned on the investment of our cash balances and short-term investments. We believe that cash received from product sales, our available cash balances net of debt owed, will be sufficient to meet our capital requirements for at
least the next twelve months. If our assumptions prove to be incorrect, we could consume our available capital resources sooner than we currently expect. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">We may borrow additional capital from institutional and commercial banking sources to fund future growth on terms that may include restrictive covenants, including covenants that restrict the operation of
our business, liens on assets, high effective interest rates and repayment provisions that reduce cash resources and limit future access to capital markets. To the extent we raise additional capital by issuing equity securities our stockholders may
experience substantial dilution. To the extent that we raise additional funds through collaboration or partnering arrangements, we may be required to relinquish some of our rights to our technologies or rights to market and sell our products in
certain geographies, or grant licenses on terms that are not favorable to us. The overall economic turmoil has generally made equity and debt financing more difficult to obtain and the terms less favorable to the companies seeking to raise
financing. As a result of these and other factors, we do not know whether additional capital will be available when needed, or that, if available, we will be able to obtain additional capital on reasonable terms. If we are unable to raise additional
capital due to the disruptions to the credit and financial markets in the United States and worldwide, or as a result of other factors, we may need to curtail planned development or commercialization activities. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Historically, we have received significant awards in funding under cooperative agreements with the United States Department of Defense,
or DoD for the INTERCEPT Blood System. Further funding awarded under federal grants and cooperative agreements for the INTERCEPT Blood System may decline when compared to historic levels. Any such funding is subject to the authorization of funds and
approval of our research plans by various organizations within the federal government, including the United States Congress. The general economic environment, coupled with tight federal budgets, has led to a general decline in the amount of
government funding available. If we are unable to obtain federal grant and cooperative agreement funding for the continued development of the INTERCEPT system in the United States at levels similar to past funding, we may need to reduce our
operating expenses, which would delay progress in some of our development programs. We recognize growing, but still relatively modest, product revenues from the sale of our platelet and plasma systems in Europe, the CIS countries, the Middle East,
and certain other countries around the world. We must conduct significant research, development, preclinical and clinical evaluation, commercialization and regulatory compliance activities for our product candidates, which, together with anticipated
selling, general and administrative expenses, are expected to result in substantial losses at least until after our platelet and plasma systems gain widespread commercial adoption in markets where our products are approved for commercialization and
in other regions around the world. Our ability to achieve a profitable level of operations in the future will depend on our ability to successfully commercialize and achieve market acceptance of our blood safety products. We may never achieve a
profitable level of operations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We pay royalties to Fenwal on product sales, at rates of 10% of net sales for the platelet
system, 3% for the plasma system, 5% for the red blood cell system, and 6.5% on sales of UVA illuminators. In December 2008, we amended and extended our supply agreement with Fenwal for the manufacture of INTERCEPT finished disposable kits for the
platelet and plasma systems through December&nbsp;31, 2013. Under the amended manufacturing agreement, we pay Fenwal a set price per kit, which is established annually, plus a fixed surcharge per kit. In addition, volume driven manufacturing
overhead will be paid or refunded if actual manufacturing volumes are lower or higher than the annually estimated production volumes. Under the amended manufacturing agreement, we are responsible for providing certain disposable kit components to
Fenwal at no cost to Fenwal. This required us to enter into supply arrangements with certain other manufacturers for those components, some of which contain minimum purchase commitments. As a result, our supply chain for certain of these components,
held as work-in-process on our consolidated balance sheet, can take over one year to complete production before being utilized in finished disposable kits. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">In November 2007, we spun-off our immunotherapy business to Anza Therapeutics, Inc., or Anza for preferred stock representing an equity interest of approximately 20% of Anza&#146;s preferred equity. We
accounted for the immunotherapy business as a discontinued operation and restated our consolidated financial statements for 2007 and prior periods to reflect that accounting treatment. We were informed in February 2009 that Anza had ceased
operations. In July 2009, we entered into a three-way license agreement with Anza and Aduro BioTech and separate agreements with each of Anza and Aduro BioTech (collectively, the Assignment Agreements). In November 2009, Anza transferred all of its
intellectual property to Aduro BioTech, or Aduro, pursuant to the terms of the Assignment Agreements. In exchange for agreeing to the transfer and for relinquishing our shares in Anza and releasing any claims against Anza, we received $0.8 million
in cash, preferred shares representing 10% of Aduro&#146;s capital and a 1% royalty on any future sales resulting from the transferred technology. Because Aduro&#146;s technology and efforts are in the very early stage of research and development,
we have no basis to assign value to the equity we have received in Aduro or that such equity will have monetary value at such time we are allowed to sell it or that we will receive any royalties from Aduro. </FONT></P>

commercialization rights that Baxter (later Fenwal) and we had granted to BioOne for both the platelet and plasma systems. Concurrently with the acquisition, Fenwal and we terminated such commercialization rights. As a consequence of the
termination, and pursuant to a pre-existing agreement with Fenwal, our commercialization rights to the platelet and plasma systems under our 2005 and 2006 agreements with Baxter became worldwide. As consideration for the acquired BioOne assets, at
the closing of the acquisition, we issued 937,886 shares of our common stock to BioOne and relinquished all of the shares we previously held in BioOne. In addition, six months from the closing date of the acquisition, we issued an additional 234,471
shares of our stock to BioOne. Accordingly, at December&nbsp;31, 2010, we had recorded the fair value of the assets acquired, consisting of commercialization rights of $2.0 million, and illuminators of $0.4 million with the excess of the purchase
price over the fair value of the asset acquired being recorded as goodwill. The $1.3 million in goodwill represents the buyer-specific value derived by Cerus as a result of acquiring the commercialization rights in certain Asian countries in order

financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, we
evaluate our estimates, including those related to revenue recognition, inventory valuation, accrued liabilities, valuation and impairment of purchased intangibles and goodwill, non-cash stock compensation assumptions, and income taxes. We base our
estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form our basis for making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from those estimates under different assumptions or conditions. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We believe the following critical accounting policies require us to make significant judgments and estimates used in the preparation of

&#147;Revenue Recognition - Arrangements with Multiple Deliverables,&#148; as applicable. Revenue is recognized when (i)&nbsp;persuasive evidence of an agreement with the funding party exists; (ii)&nbsp;services have been rendered or product has
been delivered; (iii)&nbsp;pricing is fixed or determinable; and (iv)&nbsp;collection is probable. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Revenue related to product
sales is generally recognized when we fulfill our obligations for each element of an agreement. For all sales of our INTERCEPT Blood System products, we use a binding purchase order and signed sales contract as evidence of a written agreement. We
sell INTERCEPT Blood System for platelets and plasma directly to blood banks, hospitals, universities, government agencies, as well as to distributors in certain regions. Generally, our contracts with customers do not provide for open return rights,
except within a reasonable time after receipt of goods in the case of non-conforming product. Deliverables and the units of accounting vary according to the provisions of each purchase order or sales contract. For revenue arrangements with multiple
elements, we evaluate whether the delivered elements have stand-alone value to the customer, whether the fair value of the undelivered elements is reliably determinable, and whether the delivery of the remaining elements is probable and within our
control. When all of these conditions are met, we recognize the revenue on the delivered elements. If these conditions are not met, we defer revenue until such time as all of the conditions have been met or all of the elements have been delivered.
Prior to adoption of ASU No.&nbsp;2009-13, consideration received was allocated to elements that were identified as discrete units of accounting based on the relative fair value method. Beginning January 1, 2011, consideration received is allocated
to elements that are identified as discrete units of accounting based on BESP, as consistent VSOE, is not discernable. We have determined that VSOE is not discernable due to our limited history of selling our products and variability in our pricing.
Since the Company&#146;s products are novel and unique and are not sold by others, TPE is unavailable. Freight costs charged to customers are recorded as a component of revenue and value-added-taxes, or VAT, that we invoice to our customers and

reimbursement provisions under development contracts is recognized as the costs on the projects are incurred. We receive certain United States government grants and contracts that support research in defined research projects. These grants generally

or lower than the anticipated manufacturing volumes at the time the price is established. As a result, manufacturing overhead can fluctuate and requires us to use judgment in accruing the manufacturing overhead. In addition, we use judgment in
determining whether the manufacturing overhead is a cost of our inventory and recoverable when product is sold. We use significant judgment and evaluate manufacturing variances incurred during periods of abnormally low production by considering a
variety of factors including the reasons for low production volumes, anticipated future production levels that correlate to and offset volumes experienced during abnormally low production cycles, and contractual requirements. We record manufacturing
variances incurred during periods without production as a component of cost of product revenue. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Inventory is recorded at the
lower of cost, determined on a first in, first-out basis, or market value. Our platelet and plasma system disposable kits generally have a two-year shelf life from the date of manufacture. Illuminators and replacement parts do not have regulated
expiration dates. We use significant judgment to analyze and determine if the composition of our inventory is obsolete, slow-moving, or unsalable and frequently review such determinations. Our limited history selling the INTERCEPT Blood System
limits the amount of historical data we have to perform this analysis. Generally, we write-down specifically identified obsolete, slow-moving, or known unsalable inventory that has no alternative use, using a number of factors including product
expiration dates, open and unfulfilled orders, and sales forecasts. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">&#149;<B>Accrued expenses</B> - We record accrued

activities being performed by third parties. Some of those accrued liabilities are based on estimates because billings for these activities may not occur on a timely basis consistent with the performance of the services. Specifically, accruals for
clinical trials require us to make estimates surrounding costs associated with patients at various stages of the clinical trial, pass through costs to clinical sites, contract research organization costs including fees, database development, and
reporting costs, among others. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>&#149;Purchased intangible assets and goodwill</B> &#150; We purchased certain assets from

identifying the assets acquired and in determining the fair values to record the purchased assets on our balance sheet. Some areas requiring significant judgment include cash flows, discount rates, and economic lives. In addition, under ASC Topic
805, we were required to assess the fair value of the non-controlling interest that we held in BioOne prior to the acquisition. We determined that a considerable amount of the purchase consideration was goodwill, which represents value unique to
Cerus as the holder of worldwide rights to the INTERCEPT Blood System. We may be unable to realize the recorded value of the acquired assets and our assumptions may prove to be incorrect, which may require us to write-down or impair the value of the
assets if and when facts and circumstances indicate a need to do so. We will perform an impairment test on goodwill annually or when indicators of impairment exist. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

under each issuance except for the exercise price and date issued. The outstanding warrants are classified as a liability, and as such, the fair value of the warrants is recorded on the consolidated balance sheet. At each subsequent reporting
period, the fair value of the warrants are adjusted, with changes in fair value of the warrants reflected on the consolidated balance sheet and gains and losses recognized in the consolidated statements of operations as a component of non-operating
income (expense). The fair value of the warrants is estimated using the binomial-lattice option-pricing model. This model requires that we use significant assumptions and judgment to determine appropriate inputs to the model. Some of the assumptions
that we rely on include probability of a change of control occurring, the volatility of our stock over the life of the warrant, and assumptions and inputs used to value the warrants under the Black-Scholes model should a change of control occur.

use the Black-Scholes option pricing model to determine the grant-date fair value of a stock award. We continue to apply the provisions of &#147;Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in
Conjunctions with Selling, Goods or Services,&#148; for our non-employee stock-based awards. Under the provisions, the measurement date at which the fair value of the stock-based award is measured is equal to the earlier of (i)&nbsp;the date at
which a commitment for performance by the grantee to earn the equity instrument is reached or (ii)&nbsp;the date at which the grantee&#146;s performance is complete. We recognize stock-based compensation expense for the fair value of the vested

those homogeneous groups where we are unable to obtain sufficient information to estimate the expected term in this manner, we estimate the expected term of the options granted by taking the average of the vesting term and the contractual term of

credits that may be used in future periods to offset future taxable income. We currently estimate that we may not be able to utilize all of our deferred tax assets. In addition, we may not generate future taxable income prior to the expiration of
our net operating loss carry forwards and research and development credits. Timing and significance of any estimated future taxable income is highly subjective and is beyond the control of management due to uncertainties in market conditions,
economic environments in which we operate, and timing of regulatory approval of our products. We do not recognize tax positions that have a lower than 50% likelihood of being recognized upon review by a taxing authority having full knowledge of all
relevant information. Use of a valuation allowance is not an appropriate substitute for the derecognition of a tax position. We did not have any recorded liabilities for unrecognized tax benefits at March&nbsp;31, 2011 or 2010. We recognize interest
accrued and penalties related to unrecognized tax benefits in our income tax expense. To date, we have not recognized any interest and penalties in our statements of operations, nor have we accrued for or made payments for interest and penalties. We
continue to carry a full valuation allowance on all of our deferred tax assets. Although we believe it more likely than not that a taxing authority would agree with our current tax positions, there can be no assurance that the tax positions we have
taken will be substantiated by a taxing authority if reviewed. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Results of Operations </B></FONT></P>

March&nbsp;31, 2011, compared to $5.5 million during the comparable period in the prior year. The increase in product revenue was primarily a result of an increase in disposable kit sales to customers, which was slightly offset by lower illuminator
sales during the three months ended March&nbsp;31, 2011 compared to same period in 2010. Sales of disposable platelet and plasma system kits directly to existing customers continued growing due to increased market penetration and customer adoption
of the INTERCEPT Blood System in Europe, the CIS countries, and the Middle East. We expect product revenues for both the platelet and plasma systems will continue to increase in future periods as the INTERCEPT Blood System gains market acceptance in
geographies where commercialization efforts are underway. These quarterly results may not be indicative of INTERCEPT Blood System revenue in the future. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

increase was due primarily to an increase in activities subject to reimbursement under current awards with the DoD for research activities related to our INTERCEPT Blood System for red blood cells program. </FONT></P>

comparable period in 2010. The increased loss of $0.3 million was primarily due to the change in the underlying stock price of the Company. We issued warrants to purchase an aggregate of 2.4&nbsp;million and 3.7&nbsp;million shares of common stock
in August 2009 and November 2010, respectively, in connection with offerings of our common stock. The fair value of the warrants is estimated using the binomial-lattice option-pricing model. The warrants will continue to be reported as a liability
until such time as the instruments are exercised or are otherwise modified to remove the provisions that require this treatment, at which time the warrants will be adjusted to fair value and reclassified from liabilities to stockholders&#146;
equity. At March&nbsp;31, 2011, no warrants had been exercised. If the warrants are reclassified from a liability to equity, the fair value of the warrants would be recorded in stockholders&#146; equity and no further adjustment would be made in
subsequent periods. Future changes in stock price will result in similar adjustments as needed. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; margin-left:4%; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><I>Foreign

interest incurred from borrowings on our credit facility, entered into on March&nbsp;31, 2010. Accordingly, relatively little interest expense was incurred during the three months ended March&nbsp;31, 2010 compared to March&nbsp;31, 2011. In
addition, during the three months ended March&nbsp;31, 2011, we incurred increased interest expense as a result of recently financed leasehold improvements for our headquarters. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT

 <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">At March&nbsp;31, 2011, we had cash, cash equivalents and short-term investments of $24.4
million. Net cash used in operating activities was $5.1 million for the three months ended March&nbsp;31, 2011, compared to $5.9 million during the comparable period in 2010. The decrease in net cash used in operating activities was primarily due to
changes in our operating assets and liabilities, notably inventory, accounts payable and accrued liabilities. We significantly increased our inventory balances during the three months ended March&nbsp;31, 2011. Offsetting this cash consumption was
the effect of increases to our accounts payable balances. Net cash provided by investing activities during the three months ended March&nbsp;31, 2011 was $0.2 million compared to $0.5 million during the comparable period in 2010. The decrease was
primarily due to fewer maturities of short-term investments. Over the past year, as our investments have matured we have not reinvested the proceeds into similar investments, but have generally invested the proceeds in money market funds with
original maturities less than 90 days. Net cash used in financing activities during the three months ended March&nbsp;31, 2011, was $0.5 million compared to $5.0 million of net cash provided by financing activities during the comparable period in
2010. The decrease in cash provided from financing activities during the three months ended March&nbsp;31, 2011 was primarily due to proceeds received during the three months ended March&nbsp;31, 2010 from the issuance of a long-term note payable.
Working capital decreased to $17.2 million at March&nbsp;31, 2011 from $22.1 million at December&nbsp;31, 2010, primarily due to lower balances in cash and investments and increased balances on accounts payable and on our warrant liability, which
was only partially offset by higher inventories and increased prepaid assets. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Our near-term capital requirements are
dependent on various factors, including operating costs and working capital investments associated with commercializing the INTERCEPT Blood System, costs associated with planning and conducting studies and clinical development of our red blood cell
system, costs associated with pursuing regulatory approval in geographies where we do not currently sell our platelet and plasma systems, timing and magnitude of payments under grants from the United States government, and costs related to creating,
maintaining and defending our intellectual property. Our long-term capital requirements will also be dependent on competitive developments and regulatory factors. Until we are able to generate a sufficient amount of product revenue and generate
positive net cash flows from operations, meeting our long-term capital requirements is in large part subject to access to public and private equity and debt capital markets, as well as to additional collaborative arrangements with partners or
government grants, augmented by cash generated from operations and interest income earned on the investment of our cash balances and short-term investments. We believe that cash received from product sales, our available cash balances, net of debt
owed, will be sufficient to meet our capital requirements for at least the next twelve months. If our assumptions prove to be incorrect, we could consume our available capital resources sooner than we currently expect. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We may borrow additional capital from institutional and commercial banking sources to fund future growth on terms that may include
restrictive covenants, including covenants that restrict the operation of our business, liens on assets, high effective interest rates and repayment provisions that reduce cash resources and limit future access to capital markets. To the extent we
raise additional capital by issuing equity securities our stockholders may experience substantial dilution. To the extent that we raise additional funds through collaboration or partnering arrangements, we may be required to relinquish some of our
rights to our technologies or rights to market and sell our products in certain geographies, or grant licenses on terms that are not favorable to us. The overall economic turmoil has generally made equity and debt financing more difficult to obtain
and the terms less favorable to the companies seeking to raise financing. As a result of these and other factors, we do not know whether additional capital will be available when needed, or that, if available, we will be able to obtain additional
capital on reasonable terms. If we are unable to raise additional capital, we may need to curtail planned development or commercialization activities. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Historically, we have received substantial funding under cooperative agreements with the DoD for the INTERCEPT Blood System. Further funding awarded under federal grants and cooperative agreements for the
INTERCEPT Blood Systems may decline when compared to historic levels. Any such funding is subject to the authorization of funds and approval of our research plans by various organizations within the federal government, including the United States
Congress. The general economic environment, coupled with tight federal budgets, has led to a general decline in the amount of government funding available. If we are unable to obtain federal grant and cooperative agreement funding for the continued
development of the INTERCEPT system in the United States at levels similar to past funding, we may need to reduce our operating expenses, which would delay progress in some of our development programs. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In late October 2008 we filed a shelf registration statement on Form S-3 to offer and sell up to $200.0 million of common stock,
preferred stock, warrants, and/or debt securities. We have issued approximately $34.2 million of the securities registered for issuance pursuant to the shelf registration statement. </FONT></P>

</I></B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We may encounter governmental and transfusion medicine community resistance to commercial adoption for any or all of
our products. In addition to our customers, we must also address issues and concerns from broad constituencies involved in the healthcare system, from patients, to transfusing physicians, hospitals, private and public sector payors, regulatory
bodies and public health authorities. We may be unable to demonstrate to these constituencies that the INTERCEPT Blood System is safe, effective and economical, or that the benefits of using the INTERCEPT Blood System products justify their cost.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Use of the platelet system results in some processing loss of platelets. If the loss of platelets leads to increased costs
for our customers, our customers or prospective customers believe that the loss of platelet reduces the efficacy of the transfusion unit, or our process requires changes in blood center or clinical regimens, prospective customers may not adopt our
platelet system. Certain studies have indicated that transfusion of conventionally prepared platelets may yield higher post-transfusion platelet counts (according to a measurement called &#147;corrected count increment&#148;) and may be more
effective than transfusion of INTERCEPT-treated platelets. While studies also demonstrate that INTERCEPT-treated platelets retain therapeutic function comparable to conventional platelets, customers may choose not to adopt our platelet system due to
considerations relating to corrected count increment or efficacy. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Our products do not inactivate all known pathogens, and the
inability of our systems to inactivate certain pathogens may limit their acceptance. For example, due to the biology of certain non-lipid enveloped viruses, including the hepatitis A virus, our products have not been demonstrated to inactivate these
viruses. In addition, for human parvovirus B-19, which is also a non-lipid-enveloped virus, our testing has not demonstrated a high level of inactivation. Although we have shown high levels of inactivation of a broad spectrum of lipid-enveloped
viruses, some customers may choose not to adopt our products based on considerations concerning inability to inactivate, or limited inactivation, of certain non-lipid-enveloped viruses. Similarly, although our product has been demonstrated to
effectively inactivate spore-forming bacteria, our products have not been shown to be effective in inactivating bacterial spores, once formed. In addition, since prions do not contain nucleic acid, our products do not inactivate prions. While
transmission of prions has not been a major problem in blood transfusions, and we are not aware of any competing products that inactivate prions, the inability to inactivate prions may limit market acceptance of our products. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We have conducted pre-clinical and clinical studies of our products in both <I>in vivo</I> and <I>in vitro</I> environments using
well-established tests that are accepted by regulatory bodies. When an <I>in vitro</I> test was not generally available or not well-established, we conducted <I>in vivo</I> studies in mammalian models to predict human responses. Although we have no
reason to believe that the <I>in vitro</I> and <I>in vivo</I> studies are not predictive of actual results in humans, we cannot be certain that the results of these <I>in vitro</I> and <I>in vivo</I> studies accurately predict the actual results in
humans in all cases. To the extent that actual results in human patients differs from the results of our <I>in vitro</I> or <I>in vivo</I> testing, market acceptance of our products may be negatively impacted. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Furthermore, due to limitations of detective tests, we cannot exclude that a sufficient quantity of pathogen or pathogens may still be

 <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">If customers experience operational or technical problems with the use of INTERCEPT Blood
System products, market acceptance may be reduced. For example, if adverse events arise from incomplete inactivation of pathogens, improper processing or user error, or if testing of INTERCEPT-treated blood samples fails to reliably confirm pathogen
inactivation, whether or not directly attributable to the INTERCEPT Blood System, customers may refrain from purchasing the products. In addition, there is a risk that further studies we or others may conduct will show results inconsistent with
previous studies. Should this happen, potential customers may delay or choose not to adopt our products, and existing customers may cease use of our products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Market acceptance of our products is affected by blood center budgets and the availability of reimbursement from governments, managed care payors, such as insurance companies, and other third parties. In
many cases, due to the structure of the blood products industry, we will have little control over budget and reimbursement discussions, which generally occur between blood centers and national or regional ministries of health and private payors.
Even if a particular blood center is prepared to adopt the INTERCEPT Blood System, its hospital customers may not accept, or may not have the budget to purchase, INTERCEPT-treated blood products. Since blood centers would likely not eliminate the
practice of screening donors or testing blood for pathogens prior to transfusion, even after implementing our products, some blood centers may not be able to identify enough cost offsets to afford to purchase our products. Budgetary concerns may be
further exacerbated by the economic austerity programs implemented in European countries, which may limit the adoption of new technologies, including our products. Furthermore, it is difficult to predict the reimbursement status of newly approved,
novel medical device products. In certain countries, governments have issued regulations relating to the pricing and profitability of medical products and medical products companies. The recently enacted health care reform laws in the United States
and proposed restructuring of the Medicare and Medicaid systems have also placed downward pressure on the pricing of medical products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Product adoption in Europe and other regions may be negatively affected because we do not have Food and Drug Administration, or FDA, approval for any of our products. In addition, if we do not achieve
widespread product adoption in key European countries, adoption in other countries may be affected. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The market for the
INTERCEPT Blood System is highly concentrated with few customers, including often-dominant regional or national blood collection entities. Even if our products receive regulatory approval and reimbursement is available, failure to effectively
market, promote, distribute, price or sell our products to any of these large customers could significantly delay or even diminish potential product revenue in those geographies. The market for our pathogen inactivation systems in the United States
is highly concentrated, dominated by a small number of blood collection organizations. In many countries in Western Europe and in Japan, various national blood transfusion services or Red Cross organizations collect, store and distribute virtually
all of their respective nations&#146; blood and blood components supply. In Europe, the largest markets for our products are in Germany, France, and England. In Germany, decisions on product adoption and subsequent reimbursement are expected to be
on a regional or even blood center-by-blood center basis, but depend on both local approvals and centralized regulatory approvals from the Paul Ehrlich Institute, or PEI. Product characteristics relating to platelet dose of INTERCEPT-treated
platelets that have received marketing authorization from the PEI may be incompatible with market requirements. Some potential customers may await further safety information or additional studies before choosing whether to adopt our products.
Customers or prospective customers may conduct and complete their own clinical trials before adopting our products. For instance, we have been informed by the largest group of blood centers in Germany that it will complete a clinical trial before
purchasing our products on a routine basis. We cannot predict the final trial design, number of transfusions, enrollment duration, estimated time it will take to complete such a trial, or trial outcome. While INTERCEPT-treated platelets and plasma
have received in-country regulatory approval and reimbursement rates have been established in France, adoption throughout France has been limited to certain blood centers. Decisions on product adoption in England are centralized with the National
Blood Service and we understand that the National Blood Service has decided to implement bacterial detection testing before considering pathogen inactivation. The Japanese Red Cross controls a significant majority of blood transfusions in Japan and
exerts a high degree of influence on the adoption and use of blood safety measures in Japan. The Japanese Red Cross has been reviewing preclinical and clinical data on pathogen inactivation of blood over a number of years and has yet to make a
formal determination to adopt any pathogen inactivation approach. Before the Japanese Red Cross considers our products, we understand that we may need to commit to making certain product configuration changes in order to allow the INTERCEPT Blood
System to integrate with the collection platforms of the Japanese Red Cross. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B><I>Our products, blood products treated with the INTERCEPT

STYLE="font-family:Times New Roman" SIZE="2">Our products are in various stages of development and regulatory approval, and we face the risks of failure inherent in developing medical devices and biotechnology products based on new technologies. Our
products must satisfy rigorous standards of safety and efficacy and we must adhere to quality standards regarding manufacturing and customer-facing business processes before the FDA and international regulatory authorities can approve them for
commercial use. For our product candidates, we must provide the FDA and international regulatory authorities with preclinical, clinical and manufacturing data demonstrating that our products are safe, effective and in compliance with government
regulations before the products can be approved for commercial sale. The process of obtaining FDA and other required regulatory approvals is expensive and uncertain, and typically takes a number of years. We may continue to encounter significant
delays or excessive costs in our efforts to secure necessary approvals or licenses, or we may not be successful at all. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Clinical trials are particularly expensive and have a high risk of failure. Any of our product candidates may fail in the testing phase
or may not achieve results sufficient to attain market acceptance, which could prevent us from achieving profitability. We do not know whether we will begin and conduct planned clinical trials on schedule, if at all. Significant delays in clinical
testing could materially impact our clinical trials. Criteria for regulatory approval in blood safety indications are evolving with competitive advances in the standard of care against which new product candidates are judged, as well as with
changing market needs and reimbursement levels. Clinical trial design, including enrollment criteria, endpoints, and anticipated label claims are thus subject to change, even if original objectives are being met. In addition to the reasons stated
above, clinical trials can be delayed for a variety of reasons, including delays in obtaining regulatory approval to commence a study, delays in reaching agreement on acceptable clinical study agreement terms with prospective clinical sites, delays
in obtaining institutional review board approval to conduct a study at a prospective clinical site and delays in recruiting subjects to participate in a study. We do not know whether any clinical trials will result in marketable products. Typically,
there is a high rate of failure for product candidates in preclinical and clinical trials and products emerging from any successful trial may not reach the market for several years. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Enrollment criteria for certain of our clinical trials may be quite narrow. For instance, clinical trials previously conducted using
INTERCEPT-treated plasma for patients with thrombotic thrombocytopenic purpura lasted approximately four years due in part, to the difficulties associated with enrolling qualified patients. Consequently, we may be unable to recruit suitable patients
into clinical trials on a timely basis, if at all. We cannot rely on interim results of trials to predict their final results, and acceptable results in early trials might not be repeated in later trials. Any trial may fail to produce results
satisfactory to the FDA or foreign regulatory authorities. In addition, preclinical and clinical data can be interpreted in different ways, which could delay, limit or prevent regulatory approval. Negative or inconclusive results from a preclinical
study or clinical trial or adverse medical events during a clinical trial could cause a preclinical study or clinical trial to be repeated, require other studies to be performed or cause a program to be terminated, even if other studies or trials
relating to a program are successful. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Outside the United States, regulations vary by country, including the requirements for

 <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In May 2007, we obtained a CE mark extension in our name from European Union regulators for
our platelet system and will need to obtain an extension every five years. We or our customers may also be required to conduct additional testing in order to obtain regulatory approval in countries that do not recognize the CE mark as being adequate
for commercializing the INTERCEPT Blood System in those countries. The level of additional product testing varies by country, but may be expensive or take a long time to complete. In addition, regulatory agencies are able to withdraw or suspend
previously issued approvals. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We completed our Phase III clinical trial of the platelet system in the United States in March
2001 and submitted data from this trial, along with several other modules of our pre-market approval application, to the FDA. Based on discussions with the FDA, we performed an additional blinded analysis of the clinical trial data, under the
direction of an independent expert physician panel, to determine if apparent differences between treatment groups in the category of pulmonary adverse events reported in the study were attributable to discrepancies in safety results. The
reassessment of primary patient records by the expert physician panel showed no statistically significant differences between groups. This reassessment differed from the earlier analysis of adverse events that was based on clinical trial case report
forms and had shown statistically significant differences in specific pulmonary events. We submitted a report of the analysis to the FDA for review. We understand that our reassessment of our previously completed Phase III clinical trial data will
not be sufficient to address the FDA&#146;s questions. In November 2009, we and the FDA presented a proposed clinical trial protocol for a second Phase III clinical trial to the FDA&#146;s Blood Product Advisory Committee, or BPAC. Although the BPAC
agreed with the proposed trial design, safety endpoints and efficacy endpoints, we believe we will need to reach agreement with the FDA on the means necessary to satisfy the BPAC&#146;s request for more stringent safety margins than we had proposed.
In order to meet the more stringent safety margins, we may need to enroll and collect data from more patients than what we had initially proposed to BPAC. Until the final study size and design requirements are determined, we will not be able to
assess the feasibility of a second Phase III trial. The dimensions of such a Phase III trial may be prohibitive due either to prospective cost, availability of patients in the target population, or logistics. We have no plans to initiate such a
trial unless adequate funding is secured. The additional Phase III clinical trial will need to be completed and data submitted to the FDA before we can complete our regulatory submission. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We obtained a CE mark approval in Europe for our plasma system in November 2006 and final French approval of INTERCEPT-treated plasma in
May 2007. In February 2011, the first approval for use of INTERCEPT-treated plasma was obtained from the Paul Ehrlich Institute by a blood center in Germany. In some countries, including several in Europe, we or our customers may be required to
perform additional clinical studies or submit manufacturing and marketing applications in order to obtain regulatory approval. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We have completed Phase IIIa, Phase IIIb and Phase IIIc clinical trials of the plasma system in the United States, reports for which were
filed with the FDA during 2005. We have not submitted any applications for regulatory approval of the plasma system in the United States or any other regions other than in Europe. INTERCEPT-treated plasma was recently granted orphan drug status by
the FDA for the treatment of thrombotic thrombocytopenic purpura. Although we have completed clinical trials in this patient population, the FDA may require us to complete additional clinical trials before approval would be granted. Should the FDA
require us to complete additional clinical trials, we would need to secure adequate funding before we would initiate a trial. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Before the FDA determines whether to approve the INTERCEPT Blood System products, we expect our approval applications to be reviewed by
BPAC. Should the FDA ask BPAC questions, we expect BPAC to answer those questions and make recommendations to the FDA. Even if BPAC were to recommend approval of one or more of our products, the FDA would not necessarily have to approve those
products. If BPAC were to answer FDA questions recommending against approval of one or more of our products, the FDA would have to take into consideration the points of concern raised by BPAC which could affect the approval of the products.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">If our product candidates receive approval for commercial sale in the United States, their marketing and manufacturing will
be subject to continuing FDA and other regulatory requirements, such as requirements to comply with Good Manufacturing Practice, or GMP, and ISO 13485, a quality management system standard applicable to the products we sell in Europe. The failure to
comply with these requirements on an ongoing basis could result in delaying or precluding commercialization efforts in certain geographies, including the United States, and could result in an enforcement action, which could harm our business. The
current manufacturing sites we rely upon for producing the platelet and plasma system products for international distribution and sale are not FDA-qualified facilities. It will require both time and expense to obtain such qualification. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The FDA will require, and other regulatory authorities may also require, a post-marketing clinical study, which can involve significant
expense. Governments or regulatory authorities may impose new regulations or other changes or we may discover that we are subject to additional regulations that could further delay or preclude regulatory approval and subsequent adoption of our
potential products. We cannot predict the impact of adverse governmental regulation that might arise from future legislative or administrative action. </FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We have conducted many toxicology studies to demonstrate the INTERCEPT platelet and plasma
systems&#146; safety, and we have conducted and plan to conduct toxicology studies for the INTERCEPT red blood cell system throughout the product development process. At any time, the FDA and other regulatory authorities may require further
toxicology or other studies to further demonstrate our products&#146; safety, which could delay commercialization. In addition, the FDA or foreign regulatory authorities may alter guidance at any time as to what constitutes acceptable clinical trial
endpoints or trial design, which may necessitate a redesign of our product or proposed clinical trials and cause us to incur substantial additional expense or time in attempting to gain regulatory approval. We believe the FDA and other regulatory
authorities are likely to weigh the potential risks of using our pathogen inactivation products against the incremental benefits, which may be difficult or impossible to quantify. We expect the FDA will require us to demonstrate a very low level of
potential side effects in the proposed second Phase III trial of the platelet system. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">As a result of the termination of Phase
III clinical trials of our red blood cell system due to the detection of antibody reactivity to red blood cells treated with the INTERCEPT red blood cell system in two patients in the chronic arm of the trials, we have been conducting additional
research and development activities on our red blood cell system to reduce the potential for antibody reactivity to treated red blood cells. Based upon an internal evaluation of the results from these additional research activities as well as
additional <I>in vitro</I> and <I>in vivo</I> studies and after consulting with regulatory authorities, we initiated a new Phase I clinical trial in the fourth quarter of 2008 to test modifications to the red blood cell system. That new Phase I
clinical trial was completed in early 2010, successfully meeting its primary endpoint of red cell recovery measured twenty-four hours after transfusion. In addition to red cell recovery, we also measured red cell lifespan, measured as the half-life
of red cells circulating in transfusion recipients. INTERCEPT-treated red blood cells fell within the established normal reference range for red blood cells. Non-treated red cells were above the established normal reference range. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We plan to initiate a Phase III clinical trial in Europe upon acceptance of a clinical trial application by European regulators.
Regulators could require that an additional recovery and lifespan study would need to be completed prior to initiating our planned Phase III clinical trial, which could prolong development of the red blood cell program. Significantly lower lifespan
for INTERCEPT-treated red blood cells compared to non-treated red blood cells may limit our ability to obtain regulatory approval for the product. A number of trial design issues that could impact efficacy, regulatory approval and market acceptance
will need to be resolved prior to the initiation of further clinical trials. If we are unsuccessful in advancing a modified red blood cell system through clinical trials, resolving process and product design issues or in obtaining subsequent
regulatory approvals and acceptable reimbursement rates, we may never realize a return on our research and development expenses incurred to date in the red blood cell system program. Regulatory delays can also materially impact our product
development costs. If we experience delays in testing, conducting trials or approvals, our product development costs will increase. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Regulatory agencies may limit the uses, or indications, for which any of our products are approved. For example, we believe that the INTERCEPT Blood System products will be able to claim the inactivation
of particular pathogens only to the extent we have laboratory data to support such claims. After regulatory approval for the initial indications, further studies may be necessary to gain approval for the use of the product for additional
indications. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In addition to the regulatory requirements applicable to us and to our products, there are regulatory
requirements in several countries around the world, including the United States, Germany, Canada, Austria, and Australia, and other countries, applicable to our prospective customers of INTERCEPT Blood System products, the blood centers that process
and distribute blood and blood products. In those countries, blood centers and other customers are required to obtain approved license supplements from the appropriate regulatory authorities in each country before making available blood products
processed with our pathogen inactivation systems to hospitals and transfusing physicians. Our customers may lack the resources or capability to obtain such regulatory approvals. These requirements or regulators&#146; delays in approving license
applications or supplements may deter some blood centers from using our products. Blood centers that do submit applications or supplements for manufacturing and sale may face disapproval or delays in approval that could provide further delay or
deter them from using our products. The regulatory impact on potential customers could slow or limit the potential sales of our products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

selling and marketing the platelet and plasma systems in geographies where the INTERCEPT platelet and plasma systems are approved or can be imported through the import license process. We will need to maintain and continue to increase our competence
in a number of functions, including sales, marketing, regulatory, inventory and logistics, customer service, credit and collections, risk management, and quality assurance systems. Many of these competencies require compliance with European Union
and local standards and practices, with which we have limited experience. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We have entered into contracts, generally on a
geographically exclusive basis, with distributors in countries where we have limited abilities to commercialize our pathogen inactivation products directly. We have entered into geographical distribution agreements for distribution in a number of
countries in Europe, the CIS countries, the Middle East, and Australia. We rely on these distributors to obtain any necessary in-country regulatory approvals, market and sell the INTERCEPT Blood System, provide customer and technical product
support, maintain inventories, and adhere to our quality system in all material respects, among other activities. While our contracts generally require distributors to exercise diligence, these distributors may fail to commercialize the INTERCEPT
Blood System in their respective territories. They may fail to sell product inventory they have purchased from us to end customers. Initial purchases of UVA illuminators or disposable kits by these third parties may not lead to follow-on purchases
of disposable platelet and plasma system kits. We have limited visibility into the identity and requirements of blood banking customers these distributors may have. Accordingly, we may be unable to ensure our distributors properly maintain
illuminators sold or provide quality technical services to the blood banking customers to which they sell. Agreements with our distributors typically require the distributor to maintain quality standards that are compliant with standards generally
accepted for medical devices. We may be unable to ensure that our distributors are compliant with such standards. Distributors may irreparably harm relationships with local existing and prospective customers and our standing with the blood banking
community in general. We may have little recourse, short of termination, in the event that a distributor fails to execute according to our expectations and contractual provisions. </FONT></P>

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">INTERCEPT platelet and plasma disposable kits are manufactured and assembled by Fenwal. Fenwal has agreed, through a supply agreement
signed with us in December 2008, to manufacture disposable kits for the platelet and plasma systems for us through the end of 2013. After 2013, Fenwal may terminate the supply agreement, provided that Fenwal shall have provided us thirty months
prior notice of termination. Fenwal is our sole supplier for manufacture of these products. Fenwal may fail to manufacture an adequate supply of disposable kits or to do so on a cost effective basis, which would subject us to loss of revenue and
reduced contribution margin. We also have contracts with independent suppliers, including NOVA Biomedical Corporation, or NOVA, for the manufacture of UVA illuminators and certain components of the INTERCEPT Blood System which are manufactured or
assembled at facilities not owned by Fenwal. These contractors are our sole suppliers for such components. NOVA has not manufactured UVA illuminators for a number of years. Should NOVA have difficulties manufacturing UVA illuminators, we may not be
able to supply customer demand or provide replacement UVA illuminators to existing customers. Facilities at which the INTERCEPT Blood System or its components are manufactured may cease operations for planned or unplanned reasons, causing at least
temporary interruptions in supply. We do not have qualified suppliers beyond those on whom we currently rely, and we understand that Fenwal relies substantially on sole suppliers of certain materials for our products. If we need to or choose to
identify and qualify alternate suppliers, the process will be time consuming and costly. Even a temporary failure to supply adequate numbers of INTERCEPT Blood System components may cause an irreparable loss of customer goodwill. If we conclude that
supply of the INTERCEPT Blood System or components from Fenwal and others is uncertain, we may choose to build and maintain inventories of raw materials, work-in-process components, or finished goods, which would consume capital resources and may
cause our supply chain to be less efficient. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Some components of the UVA illuminator device are no longer manufactured, which
will require us to identify and qualify replacement components and may require that we conduct additional studies, which could include clinical trials, to demonstrate equivalency or validate any required design or component changes. Future supply of
illuminators is limited to availability of components, some of which are in short supply or are no longer manufactured. We will likely be required to redesign the illuminator used in the platelet and plasma systems to manage the risk of obsolete

damage to our customer relationships. Moreover, the inclusion of components manufactured by new suppliers could require us to seek new or updated approvals from regulatory authorities, which could result in delays in product delivery. We may not
receive any such required regulatory approvals. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In the event of a failure by Fenwal or other manufacturers to perform their

tenders, some which call for us to maintain certain minimum levels of inventory. If Fenwal or third-party manufacturers fail to produce components or our finished products satisfactorily, at acceptable costs, and in sufficient quantities, we may
incur delays, shortfalls and additional expenses, or non-compliance with certain public tenders which may in turn result in permanent harm to our customer relations or loss of customers. Our platelet and plasma system disposables have received
regulatory approval for two-year shelf lives. We and our distributors may be unable to ship product to customers prior to the expiration of product shelf life, which would require that we destroy or consume the outdated inventory in product

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The equipment and materials used to collect platelets vary by manufacturer and by geographic region. Platelets may be collected from a
single donor by apheresis using an automated collection machine. Apheresis devices currently used in the United States and European markets differ, among other characteristics, in their ability to collect platelets in reduced volumes of plasma.
Platelet concentrates may also be prepared from whole blood by pooling together platelets from multiple donors. There are two commonly used methods for preparing whole blood platelets: the buffy coat method, which is used extensively in Europe, and
the pooled random donor method, which is used in the United States. Our system for platelets is designed to work with platelets collected and stored in storage solutions, called Intersol and SSP&#43;, and for platelets suspended in plasma.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In order to address the entire market in the United States, we would need to develop and test additional configurations of
the platelet system. We estimate that the majority of platelets used in the United States are collected by apheresis, though a significant minority is prepared from pooled random donor platelets derived from whole blood collections. In order to gain
regulatory approvals for a pathogen inactivation system compatible with random donor platelets, we will need to perform additional product development and testing, including additional clinical trials. Similarly, to achieve market acceptance in
certain geographies, we may be required to design, develop and test new product configurations for the platelet and plasma systems. These development activities would increase our costs significantly, and may not be successful. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Other manufacturers supplying blood component collection platforms to the market may resist our efforts to make the INTERCEPT Blood
System compatible with their platforms and may have competing pathogen inactivation technologies. Attaining compatibility with collection platforms manufactured by others may require adaptations to either the INTERCEPT Blood System or to the
collection platforms, which may be difficult to engineer, expensive to implement and test, require additional clinical trials, cause delays in regulatory approval and/or be commercially unattractive to pursue. These development activities will
increase our costs significantly, and may not be successful. Market acceptance of the INTERCEPT Blood System may be delayed until the system receives regulatory approval for use on such other equipment, if required. </FONT></P>

prototypes and the commercial products, which may increase our expenses and delay the commercialization of our products. We may determine that the red blood cell system may not be commercially feasible from potential customers&#146; perspectives. If
we fail to develop commercial versions of the INTERCEPT red blood cell system on schedule, our potential revenue would be delayed or diminished, and our potential competitors may be able to bring products to market before we do. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In addition, the design and engineering effort required to complete the final commercial product will likely be substantial and
time-consuming. As with any complex development effort, we expect to encounter design, engineering and manufacturing issues. Such issues have previously arisen, sometimes unexpectedly, and solutions to these issues have not always been readily
forthcoming. Additional unforeseen design, engineering and manufacturing issues may arise in the future, which could increase the development cost and delay commercialization of our products. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We will need to identify and contract with manufacturers who can develop processes to manufacture the compounds used in the red blood

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We expect our products to encounter significant competition. The INTERCEPT Blood System products compete with other approaches to blood
safety currently in use, and may compete with future products that may be developed by others. Our success will depend in part on our ability to respond quickly to customer and prospective customer needs and medical and technological changes brought
about by the development and introduction of new products. Competitors&#146; products or technologies may make our products obsolete or non-competitive before we are able to generate any significant revenue. In addition, competitors or potential
competitors may have substantially greater financial and other resources than we have. They may also have greater experience in preclinical testing, human clinical trials and other regulatory approval procedures. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Several companies have, or are developing, technologies that are, or in the future may be, the basis for products that will directly
compete with or reduce the market for our pathogen inactivation systems. A number of companies are specifically focusing on alternative strategies for pathogen inactivation in platelets and plasma. These alternative strategies may be more effective
in inactivating certain types of pathogens from blood products, including non-lipid-enveloped pathogens, such as hepatitis A virus, which our products have not demonstrated an ability to inactivate, or human parvovirus B-19, for which our products
have not demonstrated a high level of inactivation. While our products can effectively inactivate a broad spectrum of pathogens in blood components, including more robust inactivation of many pathogens than has been shown by other companies, market
acceptance of our products may be reduced if customers determine that competitor&#146;s products inactivate a broader range of pathogens that are of particular interest to the transfusion medicine community. In addition, customers and prospective
customers may believe that our competitor&#146;s products are safer or more cost effective than INTERCEPT Blood System products. In Europe, several companies, including Grifols S.A., Octapharma AG and MacoPharma International, are developing or
selling commercial pathogen inactivation systems or services to treat fresh frozen plasma. CaridianBCT is developing a pathogen inactivation system for blood products and has been issued CE marks for a pathogen reduction system for both platelets
and plasma. We understand that CaridianBCT has also conducted a clinical trial on a pathogen inactivation system for whole blood. CaridianBCT&#146;s product candidate, if successful, may offer competitive advantages over our INTERCEPT Blood System.
We understand CaridianBCT was recently acquired by Terumo Corporation, a large Japanese-based, multinational corporation with more mature products and relationships than we have. Our ability to commercialize our products in certain markets,
particularly Japan, may be impaired we may be unable to compete effectively with Terumo&#146;s resources and their pre-existing relationships with regulators and customers. Other companies developing competing products may also offer and sell other
blood-banking products and services. As a result, competitors may have pre-existing long-term relationships with customers and may be able to offer synergies for both pathogen inactivation and non-pathogen inactivation products that we are unable to
offer. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">New methods of testing whole blood for specific pathogens have been approved by the FDA and in Europe, as have tests
for bacteria in platelets. Other companies are marketing rapid, point-of-care bacterial tests, and developing synthetic blood product substitutes and products to stimulate the growth of platelets. Development and commercialization of any of these or
other related technologies could limit the potential market for our products. </FONT></P>

be liable if any of our products cause injury, illness or death. Although we will have completed rigorous preclinical and clinical safety testing prior to marketing our products, there may be harmful effects caused by our products that we are unable
to identify in preclinical or clinical testing. In particular, unforeseen, rare reactions or adverse side effects related to long-term use of our products may not be observed until the products are in widespread commercial use. Because of the
limited duration and number of patients receiving blood components treated with the INTERCEPT Blood System products in clinical trials, it is possible that harmful effects of our products not observed in clinical and preclinical testing could be
discovered after a marketing approval has been received. For example, in cases where we have obtained regulatory approval for our products, we have demonstrated pathogen inactivation to specified levels based on well-established tests. However,
there is no way to determine, after treatment by our products, whether our products have completely inactivated all of the pathogens that may be present in blood components. There is also no way to determine whether any residual amount of a pathogen
remains in the blood component treated by our products, and there is no way to exclude that such residual amount would be enough to cause disease in the transfused patient. For ethical reasons, we cannot conduct human testing to determine whether an
individual who receives a transfusion of a blood component containing a pathogen that was inactivated using the INTERCEPT Blood System might show positive results if tested for an antibody against that pathogen. While we believe, based on the
clinical experience of our scientists, that the level of inactivated pathogens would likely be too small to induce a detectable antibody response in diagnostic tests, we cannot exclude that a transfused patient might show positive results if tested
for an antibody against that pathogen. We could be subject to a claim from a patient that tests positive, even though that patient did not contract a disease. Later discovery of problems with a product, manufacturer or facility may result in
additional restrictions on the product or manufacturer, including withdrawal of the product from the market. We are subject to risks and costs of product recall, which include not only potential out-of-pocket costs, but also potential interruption
to our supply chain. In such an event, our customer relations would be harmed and we would incur unforeseen losses. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We

and costs related to creating, maintaining and defending our intellectual property. Our long-term capital requirements will also be dependent on competitive developments and regulatory factors. Until we are able to generate a sufficient amount of
product revenue and generate positive net cash flows from operations, meeting our long-term capital requirements is in large part subject to access to public and private equity and debt capital markets, as well as to additional collaborative
arrangements with partners or government grants, augmented by cash generated from operations and interest income earned on the investment of our cash balances and short-term investments. We believe that our available cash balances, net of debt owed

and to governmental and private payors, which may reduce or altogether eliminate our gross profit on sales. At our present sales levels of the platelet and plasma systems, our costs to manufacture, distribute, market, sell, support and administer
the systems are in excess of revenue. Contribution from product sales is unlikely to exceed the costs we incur in research, development, and commercialization of the INTERCEPT Blood System for the near-term. We expect our losses to continue at least
until the INTERCEPT Blood System achieves more significant market acceptance. To the extent that we reach agreement on a clinical pathway with the FDA for our platelet or plasma products and if we choose to pursue such opportunities, we would expect

challenged, invalidated or circumvented. Our patent rights may not provide us with proprietary protection or competitive advantages against competitors with similar technologies. Others may independently develop technologies similar to ours or
independently duplicate our technologies. For example, a United States patent issued to a third-party covers methods to remove psoralen compounds from blood products. We have reviewed the patent and believe there exists substantial questions
concerning its validity. We cannot be certain, however, that a court would hold the patent to be invalid or not infringed by our platelet or plasma systems, if and when those products are sold in the United States. Our key patents generally expire
at various dates between 2012 and 2027. Recent patent applications will, if granted, result in patents with later expiration dates. In addition, we have a license from Fenwal to United States and foreign patents relating to the INTERCEPT Blood
System, which expire from 2016 to 2023. Due to the extensive time required for development, testing and regulatory review of our potential products, our patents may expire or remain in existence for only a short period following commercialization.
This would reduce or eliminate any advantage of the patents. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We cannot be certain that we were the first to make the
inventions covered by each of our issued patents or pending patent applications or that we were the first to file patent applications for such inventions. We may need to license the right to use third-party patents and intellectual property to
continue development and commercialization of our products. We may not be able to acquire such required licenses on acceptable terms, if at all. If we do not obtain such licenses, we may need to design around other parties&#146; patents, or we may
not be able to proceed with the development, manufacture or sale of our products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Our patents do not cover all of the

secrets or know-how or determine the scope and validity of others&#146; proprietary rights. Patent litigation is costly. In addition, we may require interference proceedings before the United States Patent and Trademark Office to determine the
priority of inventions relating to our patent applications. Litigation or interference proceedings could be expensive and time consuming, and we could be unsuccessful in our efforts to enforce our intellectual property rights. </FONT></P>

protect our proprietary technology and processes, in part, by confidentiality agreements with employees and certain contractors. These agreements may be breached and we may not have adequate remedies for any breach or our trade secrets may otherwise
become known or be independently discovered by competitors. To the extent that our employees, consultants or contractors use intellectual property owned by others, disputes also may arise as to the rights in related or resulting know-how and
inventions. </FONT></P>

international operations are subject to risks typical of an international business, including, among other factors: differing political, economic, and regulatory climates, different tax structures, and foreign exchange volatility. We do not

purchase finished disposable kits for our platelet and plasma systems and incur operating expenses in Euros and other foreign currencies. Our exposure to foreign exchange rate volatility is a direct result of our product sales, cash collection and
expenses to support our international operations. Foreign exchange rate fluctuations are recorded as a component of interest (expense) and other, net on our consolidated statements of operations. Significant fluctuations in the volatility of foreign
currencies relative to the United States dollar may materially affect our results of operations. Currently we do not have any near-term plans to enter into a formal hedging program to mitigate the effects of foreign currency volatility. </FONT></P>

General Corporation Law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders. In addition, Section&nbsp;203 of the Delaware General
Corporation Law, unless its application has been waived, provides certain default anti-takeover protections in connection with transactions between the company and an &#147;interested stockholder&#148; of the company. Generally, Section&nbsp;203
prohibits stockholders who, alone or together with their affiliates and associates, own more than 15%&nbsp;of the subject company from engaging in certain business combinations for a period of three years following the date that the stockholder
became an interested stockholder of such subject company without approval of the board or the vote of two-thirds of the shares held by the independent stockholders. Our board of directors has also adopted a stockholder rights plan, or &#147;poison
pill,&#148; which would significantly dilute the ownership of a hostile acquirer. Additionally, provisions of our amended and restated certificate of incorporation and bylaws could deter, delay or prevent a third party from acquiring us, even if
doing so would benefit our stockholders, including without limitation, the authority of the board of directors to issue, without stockholder approval, preferred stock with such terms as the board of directors may determine. </FONT></P>
