pursuant to the instructions to Form 10-Q and Article&nbsp;10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the

&#147;Revenue Recognition&#148; (&#147;SAB 104&#148;). SAB 104 rescinds Staff Accounting Bulletin No.&nbsp;101, &#147;Revenue Recognition in Financial Statements&#148; and provides guidance on the recognition, presentation and disclosure of revenue
in financial statements. The Company recognizes revenue in accordance with SAB 104 and Emerging Issues Task Force (&#147;EITF&#148;) 00-21, &#147;Accounting for Revenue Arrangements with Multiple Deliverables,&#148; as applicable. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Our main sources of revenues through September&nbsp;30, 2006, have been our research and development activities and agreements. Historically, development funding has
consisted of payments made (i)&nbsp;by Baxter Healthcare Corporation (&#147;Baxter&#148;), a subsidiary of Baxter International Inc. (&#147;Baxter International&#148;), to us as reimbursement for development spending in excess of the levels
determined by Baxter and us and (ii)&nbsp;by MedImmune, Inc. (&#147;MedImmune&#148;) to us as reimbursement for certain fee-for-service development activities. Revenue related to the cost reimbursement provisions under development contracts is
recognized as the costs on the project are incurred. Revenue related to at-risk milestones specified under development contracts is recognized as the milestones are achieved. Payments for achieved milestones are non-refundable and are not subject to
future performance. We evaluate licenses and research and development agreements that contain multiple elements in accordance with EITF 00-21 and accordingly allocate revenue to each element of the agreement based on their relative fair values.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We receive milestone and upfront consideration from collaborative partners, including MedImmune and BioOne Corporation (&#147;BioOne&#148;). This
milestone and upfront consideration is earned through our research and development activities surrounding the collaborative agreements. Upfront consideration is generally deferred upon receipt and recognized ratably over the periods to which the
payments relate. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We receive certain United States government grants that support our efforts in defined research projects. These grants generally provide
for reimbursement of approved costs incurred as defined in the various grants. Revenue associated with these grants is recognized as costs under each grant are incurred. In accordance with Statement of Financial Accounting Standards No.&nbsp;2,
&#147;Accounting for Research and Development Expenses,&#148; research and development costs are charged to expense when incurred. Research and development expenses include salaries and related expenses for scientific personnel, payments to
consultants, supplies and chemicals used in in-house laboratories, costs of research and development facilities, depreciation of equipment and external contract research expenses, including clinical trials, preclinical safety studies, other
laboratory studies, process development and product manufacturing for research use. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Our use of estimates in recording accrued liabilities for research and
development activities affects the amounts of research and development expenses recorded and as a direct result of estimates, revenue recorded from development funding and government grants and collaborative agreements. Actual results may differ
from those estimates under different assumptions or conditions. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Effective February&nbsp;1, 2006, we entered into an agreement with Baxter, which gave us
the exclusive commercialization rights to the INTERCEPT Blood Safety System for platelets and plasma (the &#147;platelet system&#148; and the &#147;plasma system&#148;). As a result of the agreement, we now record product sales of the platelet
system, rather than our negotiated share of gross profits from such sales under the prior agreement with Baxter. Also as a result of the February 2006 agreement, we record cost of revenues, which, for the three and nine month periods ended
September&nbsp;30, 2006, consisted solely of the value of platelet system inventory sold. Inventories consist of finished goods components of the platelet system and are recorded at the lower of cost or market value, determined on a first-in,
first-out basis. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B><I>Stock based compensation </I></B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman"

for calculating the tax effects (if any) of stock-based compensation expense pursuant to SFAS 123R. The alterative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (APIC pool)
related to the tax effects of employee stock-based compensation, and to determine the subsequent impact to the APIC pool and the consolidated statements of operations and cash flows of the tax effects of employee stock-based compensation awards that

Other than Employees for Acquiring, or in Conjunction with Selling, Goods or Services&#148; (EITF 96-18) for our non-employee stock-based awards. Under EITF 96-18, the measurement date at which the fair value of the stock-based award is measured is
equal to the earlier of 1) the date at which a commitment for performance by the counter party to earn the equity instrument is reached or 2) the date at which the counter party&#146;s performance is complete. We recognize stock-based compensation
expense for the fair value of the vested portion of the non-employee awards in our consolidated statements of operations. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B><I>Recent Accounting

inconsistencies in guidance found in various prior accounting pronouncements. SFAS 157 is effective for fiscal years beginning after November&nbsp;15, 2007. Earlier adoption is permitted, provided the company has not yet issued financial statements,
including for interim periods, for that fiscal year. We are currently evaluating the impact of SFAS 157, but do not expect the adoption of SFAS 157 to have a material impact on our consolidated financial position, results of operations or cash

certain disclosures of uncertain tax matters; specifies how reserves for uncertain tax positions should be classified on the balance sheet; and provides transition and interim period guidance, among other provisions. FIN 48 is effective for fiscal

compensation expense based on the fair value of the underlying common stock as of the grant date, recognized over the vesting period. As of September&nbsp;30, 2006, all restricted stock units pertaining to the March 2004 grants had vested and all

FACE="Times New Roman" SIZE="2">Beginning with our first quarter of 2006, we adopted FAS 123R. See Note 1 for a description of our adoption of FAS 123R. We currently use the Black-Scholes option pricing model to determine the fair value of stock
options and employee stock purchase plan shares. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of complex
and subjective variables. The variables used to calculate the fair value of stock based payment awards using the Black-Scholes option pricing model, include our expected stock price volatility, actual and projected employee stock option exercise

exercise and post-vesting termination behavior. To make this estimation, we analyze the population of options granted by discreet, homogeneous groups. For those homogeneous groups where we are unable to obtain sufficient information to estimate the
expected term for a particular group, we estimate the expected term of the options granted by taking the average of the vesting term and the contractual term of the option, as illustrated in Staff Accounting Bulletin No.&nbsp;107 (&#147;SAB

those estimates. We use historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. We estimate the historic pre-vesting forfeiture rates by groups that
possess a degree of homogeneity regarding average time to vest and expected term. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><I>Estimated Volatility </I></FONT></P> <P
STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We estimate the volatility of our common stock by using both historical volatility of our common stock and implied volatility in market traded options in accordance with
SAB 107. Our decision to use both historical volatility and implied volatility was based upon the limited availability of actively traded options on our common stock and our assessment that due to the limited availability of actively traded options,
historical volatility should be given greater prominence in our decision as we believe it is more representative of future stock price. As such, we have calculated our estimated volatility by weighting both historical volatility and implied
volatility. We have used significant judgment in making these estimates and we will continue to monitor the availability of actively traded options on our common stock. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT

Stock options and Series B preferred stock outstanding during the three and nine months ended September&nbsp;30, 2006 and the three months ended September&nbsp;30, 2005, were not included in the computation of diluted net loss per share because
their effect was antidilutive. For the nine months ended September&nbsp;30, 2005, diluted net income per share included the effect of 1,045,000 shares of common stock calculated on options outstanding using the treasury stock method and the Series B

STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Effective February&nbsp;1, 2006, we entered into a restructuring of our agreements with Baxter related to the INTERCEPT Blood System. Under the terms of the February 2006
agreement, we gained worldwide rights to the INTERCEPT Blood System for platelets (the &#147;platelet system&#148;) and the INTERCEPT Blood System for plasma (the &#147;plasma system&#148;) previously held by Baxter, excluding certain Asian
countries covered in agreements with BioOne. As a result of the agreement, we record all of the platelet and plasma system revenues. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Prior to entering the
February 2006 agreement, we received 33.5 percent of the adjusted gross margins from sales of the platelet system, which are shown as product revenue on our statements of operations. Baxter has agreed to supply certain transition services, including
regulatory, technical and administrative support in 2006, at our expense and to conduct certain continued development efforts relating to the plasma system at Baxter&#146;s expense. Also as a result of this agreement, we repaid a $4.5 million
promissory note and the related accrued interest during the three months ended March&nbsp;31, 2006. This promissory note had been payable to Baxter since February 2005 and had an original maturity date of December 2006 with interest of 8%. At
September&nbsp;30, 2006, we had approximately $3.5 million in remaining deferred gains recorded on our condensed consolidated balance sheet which may be used to offset qualifying expenses we incur associated with the commercialization of the
platelet and plasma systems. The nature of these qualifying expenses may be for cost of product revenue, selling, general and administrative, or research and development. For the nine months ended September&nbsp;30, 2006, we have recognized gains of
approximately $2.3 million associated with these qualifying expenses. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Baxter has agreed to manufacture systems and components, on a cost-plus basis,
through 2008. Since these manufacturing agreements do not require Baxter to manufacture in an FDA-approved facility, we will need to undertake additional validation steps before use of such items in the United States. Baxter has agreed to supply
only very limited types of components for the prototype red blood cell system. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B>Note 7 &#150; Transactions with BioOne </B></FONT></P> <P
STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">In April 2004, we made an investment in the common stock of BioOne, a privately-held Japanese corporation. BioOne was formed in 2004 to develop technologies to improve
the safety of blood products in Asia, and is funded by equity investments from Japanese venture capital firms, other corporations and individual investors. Because our initial investment represented greater than 20% of BioOne&#146;s voting equity
securities, we accounted for this investment under the equity method for the three months ended June&nbsp;30, 2004, and reported our share of BioOne&#146;s net losses as a loss from equity affiliate and as a reduction of our investment. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">In June 2004, Baxter and we entered into an agreement with BioOne for commercialization of the INTERCEPT Blood System for platelets in parts of Asia. Under the terms
of the agreement, BioOne is responsible, at its expense, for seeking regulatory approvals and will have exclusive rights to market and distribute the INTERCEPT Blood System for platelets in Japan, China, Taiwan, South Korea, Thailand, Vietnam and
Singapore, following their receipt of regulatory approval in each of those countries. In July 2004 and October 2004, Baxter and we each received up-front payments of $10.0 million from BioOne. Our portion of the up-front payments is being deferred
and recognized ratably as development funding over the development period. The agreement also provides for contingent milestone payments and royalties on future product sales, which would be shared equally by Baxter and us. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">In December 2004, Baxter and we signed a letter of intent with BioOne to enter into a definitive agreement for commercialization of the INTERCEPT Blood System for plasma
in parts of Asia. Under the letter of intent, we received a payment of $3.0 million from BioOne, which was recorded as deferred revenue as of December&nbsp;31, 2004. A definitive agreement with BioOne for the plasma system was signed </FONT>

<FONT FACE="Times New Roman" SIZE="2">by Baxter and us in June 2005. In December 2005 we received additional up-front payments of $2.0 million in cash and $5.0 million in BioOne&#146;s equity,
both of which were recorded upon receipt as deferred revenue to be amortized over the remaining development period. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We made an additional $1.1 million
investment in BioOne equity securities in July 2004. As a result of dilution from additional concurrent third party investments in BioOne, we then held less than 20% of the outstanding voting securities of BioOne and began accounting for our
investment in BioOne under the cost method. As partial payment for rights to the plasma system in BioOne&#146;s territories, in December 2005 we received shares and a warrant, exercisable at a nominal price, for additional shares valued at $5.0
million based on a concurrent financing with new and existing investors completed by BioOne. We continue to hold less than a 20% interest in the voting securities of BioOne and thus continue to account for our investment under the cost method. As of
September&nbsp;30, 2006, our investment in BioOne was $6.2 million and was included in long-term investments on our balance sheets. We evaluate the carrying value of this investment periodically and have determined our carrying value is fairly
stated. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B>Note 8 &#150; Preferred Stock </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Baxter holds
3,327 shares of our Series B preferred stock, which represents 100% of the total outstanding shares of Series B preferred stock. Series B preferred stock has no voting rights, except with respect to the authorization of any class or series of stock
having preference or priority over the Series B preferred stock as to voting, liquidation or conversion or with respect to the determination of fair market value of non-publicly traded shares received by the holder of Series B stock in the event of
a liquidation, or except as required by Delaware law. At any time, the holder may convert each share of Series B preferred stock into 100 common shares. If all shares of Series B preferred stock were converted to common stock, 332,700 common shares
would be issued, which represents approximately 1% of our outstanding common shares as of September&nbsp;30, 2006. We have the right to redeem the Series B preferred stock prior to conversion for a payment of $9.5 million. </FONT></P> <P

we had reached agreement to settle the class action, pending since 2003 in the United States District Court for the Northern District of California, against certain of our current and former directors, officers and us. The amended and consolidated
complaint alleged that the defendants had violated the federal securities laws by making allegedly false and misleading predictions regarding the initiation and completion of clinical trials, submission of regulatory filings, receipt of regulatory
approval and other milestones in the development of the platelet, plasma and red blood cell systems. The plaintiffs sought unspecified damages on behalf of a purported class of purchasers of our securities during the period from December&nbsp;9,
2000, through January&nbsp;30, 2003. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">On August&nbsp;31, 2006, we also announced that we had reached agreement to settle the derivative lawsuit, pending
since 2003 in the Superior Court for Contra Costa County, in which certain of our current and former directors and officers were named as defendants and the Company was named as a nominal defendant. The plaintiffs were Cerus stockholders who sought
to bring derivative claims on behalf of the Company against the defendants. The consolidated complaint alleged breach of fiduciary duty and related claims and sought an unspecified amount of damages. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Pursuant to the settlement agreements, the plaintiffs in the class action and in the stockholders&#146; derivative lawsuit will release defendants from all known and
unknown claims related to such litigation, without any admission of wrongdoing or liability by any party. Under these settlement agreements, the total cash settlements will be funded entirely by insurance carriers under our directors&#146; and
officers&#146; liability insurance policy and will have no financial impact on us. Additionally, under the derivative suit settlement, we agree to take or continue certain corporate governance measures. These measures involve, among others, our
making a good faith diligent effort to add one or two independent directors to our Board of Directors by September&nbsp;1, 2007, (and if not added by such time, retaining a professional search firm to assist in the identification of such independent
directors, using our best efforts to add one or two independent directors to the Board of Directors by December&nbsp;31, 2008); and our committing through January&nbsp;1, 2009, unless otherwise required by law, that two thirds of our Board of
Directors will in good faith and with diligent effort consist of independent directors. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">The settlement will become effective upon the satisfaction of a
number of conditions, including, among others, the timely execution of a final stipulation, the approval of the settlement by the courts, and the final and non-appealable entry of a judgment by the courts dismissing the class action and derivative
lawsuits with prejudice. Under terms of the settlement, we believe that this matter will not have a material effect on our results of operations or financial position; however, we cannot predict when, if ever, the settlement will become effective.

STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Since our 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, more recently, immunotherapies for cancer and infectious disease. With the exception of a non-recurring gain recognized during the three months ended March&nbsp;31, 2005, we have been generally unprofitable since inception and,
as of September&nbsp;30, 2006, had an accumulated deficit of approximately $314.4 million. Except for the platelet system, for which the European Union approved issuance of a CE mark, all of our product candidates are in the research and development
stage. In late 2005, we filed a CE mark application for the plasma system and an investigational new drug application, or IND, with the United States Food and Drug Administration, or FDA, for CRS-100, a product candidate employing our attenuated
<I>Listeria</I> technology platform, and we re-entered Phase I human clinical trials in the United States for the red blood cell system in the three months ended September&nbsp;30, 2006. Our primary source of revenue is from milestone and
development contracts and collaborative, U.S. government grants. More recently, we have been receiving European product revenues from the sale of our platelet system. We anticipate continued growth of our product sales as we penetrate European
markets. We must conduct significant research, development, preclinical and clinical evaluation, commercialization and regulatory compliance activities on our product candidates that, together with anticipated general and administrative expenses,
are expected to result in substantial losses at least until after commercialization of additional products. 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 and immunotherapy product candidates. We may never achieve a profitable level of operations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Through
September&nbsp;30, 2006, in addition to the product revenues from sales of our platelet system, we have recognized revenue from an ongoing development agreement with MedImmune and commercialization agreements with BioOne, as well as from grants and
cooperative agreements from the Armed Forces and the National Institutes of Health, or NIH. Under the agreements with MedImmune and BioOne, we are receiving development funding and may receive contingent milestone payments and royalties on future
product sales. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">As of September&nbsp;30, 2006, we had cumulatively received $1.5 million of upfront and milestone payments from MedImmune under the terms
of the agreement, consisting of a $1.0 million up-front payment and a $0.5 million milestone payment, and had received a total of $20.0 million in cash payments and equity securities from BioOne. Under the MedImmune agreement, we had also received
development funding. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We also entered into cooperative agreements with the Armed Forces and received grants and contracts from the NIH to conduct certain

agreement with Baxter related to the INTERCEPT Blood System. Under terms of the February 2006 agreement, we gained worldwide rights to the INTERCEPT platelet and plasma systems previously held by Baxter, excluding certain Asian countries covered in
agreements with BioOne. We previously acquired worldwide commercialization rights for the red blood cell system from Baxter. Beginning in 2007, we will pay Baxter royalties on product sales, with a rate of 10% of net sales for the platelet system,
3% for the plasma system and 5% for the red blood cell system. This royalty structure replaces the terms of previous agreements with Baxter under which we had received a defined share of gross profit from product sales. Under the terms of the
February 2006 agreement, Baxter has agreed to supply certain transition services to us through 2006 at our expense, including regulatory, technical and back-office support, and to conduct certain continued development efforts relating to the plasma
system at its expense. Baxter has agreed to manufacture systems and components for the platelet and plasma systems on a cost-plus basis through December&nbsp;31, 2008, and </FONT>

had entered into a definitive agreement to sell its Transfusion Therapies business, the unit of Baxter that has performed many of the manufacturing and supply chain activities related to our relationship with Baxter, to an investment group led by
Texas Pacific Group. Subject to regulatory approvals and other customary closing conditions, Baxter and Texas Pacific Group expect to close the transaction by the first quarter of 2007. Our agreement with Baxter will remain in effect, although

million in deferred gains recorded on our condensed consolidated balance sheet which may be used to offset qualifying expenses we incur associated with the commercialization of the platelet and plasma systems. The nature of these qualifying expenses
may be for cost of product revenue, selling, general and administrative, or research and development. For the nine months ended September&nbsp;30, 2006, we have recognized gains of approximately $2.3 million associated with these qualifying
expenses. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Under the terms of the February 2006 agreement, we are responsible for the commercialization and development of the platelet and plasma systems,

milestone payments and development funding for such programs from Baxter, BioOne, the Armed Forces and others. We also anticipate increasing our expenditures in support of clinical trials and device development of our red blood cell system, as well

increased $2.7 million, or 14%, to $21.4 million. The increase in revenues was attributable to milestone and development funding from BioOne received during the second half of 2005 and recognized ratably over the estimated remaining development
period of the plasma system. At September&nbsp;30, 2006, we estimated the remaining development period of the plasma system to be three months. In addition, our product sales contributed to the relative increase in 2006, reflecting revenue from the
total sales of the platelet system as opposed to the results in 2005, which reflected our 33.5% of gross margins from total platelet system sales. Partially offsetting the 2006 increases in milestone and development and product revenue are
reductions in the revenue received from government grants. At September&nbsp;30, 2006, in excess of $1.9 million in government grant awards are pending. We anticipate the release of these awards in the remainder of 2006 and in 2007. </FONT></P> <P

deferred revenues recorded on our balance sheet at September&nbsp;30, 2006, are being amortized and recognized as revenue over the remaining estimated development periods to which they relate. All of the estimated development periods are expected to
be completed by the end of 2006. Net cash provided by investing activities during the nine months ended September&nbsp;30, 2006, was $12.5 million, primarily due to maturities of short-term investments. Net cash provided by financing activities
during the nine months ended September&nbsp;30, 2006, was $38.7 million, compared to cash used in financing activities of $34.1 million for the same period in 2005. The increase in 2006 compared to 2005 is largely due to the issuance of 5,175,000
shares of common stock in a public offering in March 2006, providing net proceeds of $42.4 million, offset by the repayment of a loan from Baxter Capital of $4.5 million plus accrued interest. During the same period in 2005, we repaid $34.5 million
on the note due to Baxter. Working capital increased to $65.2 million at September&nbsp;30, 2006, from $27.7 million at December&nbsp;31, 2005, primarily due to the receipt of proceeds from our stock offering and, to a lesser degree, from the gain

together with anticipated cash flows from existing development and grant arrangements, will be sufficient to meet our capital requirements through at least early 2008. These near-term capital requirements are dependent on various factors, including
the progress and costs of development and commercialization of the INTERCEPT Blood System and research and development of our immunotherapy programs, payments from our development and commercialization partners, including BioOne, cash collected from
product sales, and from the United States government, and costs related to creating, maintaining and defending our intellectual property. Our long-term capital requirements will be dependent on these factors and on our ability to raise capital
through public or private equity or debt financings or through additional collaborative arrangements or government grants, development progress in our immunotherapy programs, regulatory approval and successful commercialization of the INTERCEPT
Blood System and other product candidates, competitive developments and regulatory factors. Future capital funding transactions may result in dilution to our investors, and may not be available on favorable terms or at all. In August&nbsp;2001, we
filed a shelf registration statement on Form S-3 to offer and sell up to $300.0 million of common stock and/or debt securities. In June&nbsp;2003, we completed a public offering of 6,000,000 shares of common stock with gross proceeds, calculated for
registration statement purposes, of $57.8 million under the shelf registration statement. In March 2006, we completed a public offering of 5,175,000 shares of common stock with gross proceeds, calculated for registration statement purposes, of $45.3
million under the shelf registration statement. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B>Financial Instruments </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT

gains or losses reported as a separate component of stockholders&#146; equity, if material. Our investment policy is to manage our marketable securities portfolio to preserve principal and liquidity while maximizing the return on the investment
portfolio to assist us in funding our research and development activities. Unrealized gains for the nine months ended September&nbsp;30, 2006, totaled $0.3 million. Our investments primarily consist of short-term money market mutual funds, United
States government obligations and commercial paper. Of our cash, cash equivalents and short-term investments balance of $69.6 million at September&nbsp;30, 2006, approximately 61% have maturity dates less than 90 days from September&nbsp;30, 2006,
and approximately 8% have maturities of greater than 90 days and less than one year, and approximately 31% have maturities in excess of one year from September&nbsp;30, 2006. We do not believe our exposure to interest rate risk to be material given
the short-term nature of our investment portfolio. Given the investment mix of our portfolio at September&nbsp;30, 2006, and our anticipated liquidity needs, we currently believe we have the ability and intent to hold our securities to their
maturities without recognizing any gains or losses from sales prior to maturity. We do not believe our unrealized losses reflect more than a temporary decline in value of our marketable securities held. The following table illustrates our cash, cash

violated the federal securities laws by making allegedly false and misleading predictions regarding the initiation and completion of clinical trials, submission of regulatory filings, receipt of regulatory approval and other milestones in the
development of the platelet, plasma and red blood cell systems. The plaintiffs sought unspecified damages on behalf of a purported class of purchasers of our securities during the period from December&nbsp;9, 2000, through January&nbsp;30, 2003.

Contra Costa County, in which certain of our current and former directors and officers were named as defendants and the Company was named as a nominal defendant. The plaintiffs were Cerus stockholders who sought to bring derivative claims on behalf
of the Company against the defendants. The consolidated complaint alleged breach of fiduciary duty and related claims and sought an unspecified amount of damages. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman"

impact on us. Additionally, under the derivative suit settlement, we agree to take or continue certain corporate governance measures. These measures involve, among others, our making a good faith diligent effort to add one or two independent
directors to our Board of Directors by September&nbsp;1, 2007, (and if not added by such time, retaining a professional search firm to assist in the identification of such independent directors, using our best efforts to add one or two independent
directors to the Board of Directors by December&nbsp;31, 2008); and our committing through January&nbsp;1, 2009, unless otherwise required by law, that two thirds of our Board of Directors will in good faith and with diligent effort consist of

<FONT FACE="Times New Roman" SIZE="2">safety information or additional studies would be required before adopting our products. There is some volume loss in the yield of blood products as a result
of our pathogen inactivation process. In addition, our platelet system process today is not fully compatible with the common practice of collecting two units of platelets from a single apheresis donor. If the volumetric reduction of blood product
leads to increased costs, or our process requires changes in blood center or clinical regimens, customers may not adopt our platelet system product. Our products do not inactivate all known pathogens, and the inability of our systems to inactivate
certain pathogens may limit their acceptance. In addition, our products may not demonstrate economic value sufficient to offset their price, imposing a financial burden on the healthcare system that may limit market acceptance. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">For logistical and financial reasons, the transfusion industry has not always integrated new technologies into their processes, even those with the potential to improve
the safety of the blood supply. Our products may require significant changes to our potential customers&#146; blood component collection methods, space and staffing requirements and require significant capital investment. Even if our product
candidates receive regulatory approval for commercial sale, blood centers, physicians, patients and healthcare payors may not believe that the benefits of using the INTERCEPT Blood System justify their additional cost. 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 Blood System-treated blood samples fails to reliably confirm pathogen inactivation, whether or not directly attributable to a shortcoming of the INTERCEPT Blood System, customers may refrain from purchasing the products. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Market acceptance of our products may also be affected by the availability of reimbursement from governments, managed care payors, such as insurance companies, or other
third parties. We have no experience negotiating reimbursement of medical products. In many cases, due to the structure of the blood products industry, we will have little control over reimbursement discussions, which generally occur between blood
centers and national or regional ministries of health and private payors. For example, while the platelet system has been approved in France for use by blood centers in treating platelets, commercial adoption has been delayed pending determination
of reimbursement rates for pathogen inactivated platelets. We may be required to seek explicit reimbursement in European countries for our plasma system, if and when approved by regulatory authorities, even though other competing pathogen
inactivation products for plasma have been approved and are being reimbursed in Europe presently. It is difficult to predict the reimbursement status of newly approved, novel medical device or biopharmaceutical products. In certain foreign markets,
governments have issued regulations relating to the pricing and profitability of medical products and medical products companies. There also have been proposals in the United States, at both the Federal and state government level, to implement such
controls. The widespread adoption of managed care in the United States has also placed pressure on the pricing of medical products. These pressures can be expected to continue and may limit the prices we can obtain for our products. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We may be required to reduce the sales price for our products in order to make them economically attractive to our customers and to governmental and private payors,
which would reduce and may eliminate our gross profit on sales. At our present low unit sales levels of the platelet system, our costs to manufacture and sell the platelet system are in excess of revenue. We may be unable to increase sales to a
level sufficient to generate profit contribution. We believe that future product sales in Europe and other regions may be negatively affected because we do not have FDA approval for any of our products. If the INTERCEPT Blood System products fail to
achieve market acceptance, we may never become profitable. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="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 properly market, price or sell our products to any of these large customers could
significantly 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 nation&#146;s blood and blood components supply. In Europe, the largest markets for
our products are in England, Germany and France. Decisions on product adoption in England are centralized with the National Blood Service, where general cost containment pressures have delayed consideration of the INTERCEPT Blood System to date. In
Germany, decisions on product adoption and subsequent reimbursement are expected to be on a blood center-by-blood center basis, but depend on both local and centralized regulatory approvals. While the platelet system has received in-country
regulatory approval in France, adoption has been delayed in the absence of national reimbursement rates for pathogen inactivated platelets. The Japanese Red Cross controls a significant majority of blood transfusions in Japan. If approvals are not
obtained to market our products in these countries, or if the products are not adopted in these countries, our potential product revenue will be significantly decreased. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT

foreign countries impose substantial requirements upon the manufacturing and marketing of products such as those we are developing. The process of obtaining FDA and other required regulatory approvals is long, expensive and uncertain, and typically
takes a number of years, depending on the type, complexity and novelty of the product. We may 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"><FONT FACE="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 the Blood Products Advisory
Committee, or BPAC, an advisory committee convened by and reporting to the FDA. BPAC would then make a recommendation to the FDA for, or against, approval. Even if BPAC were to recommend approval of one or more of our products, the FDA would not
necessarily approve those products. If BPAC were to recommend against approval of one or more of our products, it is likely that the FDA would not approve those products. Before entering human clinical trials, product candidates in our immunotherapy
programs beyond CRS-100 likely will be subject to review by the Recombinant DNA Advisory Committee of the National Institutes of Health, which could delay initiation of clinical trials. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
FACE="Times New Roman" SIZE="2">If our product candidates receive approval for commercial sale, their marketing and manufacturing will be subject to continuing FDA and other regulatory requirements, such as requirements to comply with Good
Manufacturing Practice and ISO 13485, a quality management system standard applicable to the products we sell in Europe. The failure to comply with these requirements could result in delaying or precluding commercialization efforts in certain
geographies, including the United States, and could result in enforcement action, which could harm our business. Gaining FDA approval for our platelet and plasma products would require additional investment and time, because the current
manufacturing sites we rely upon for producing the platelet and plasma system products for European distribution are not FDA-qualified facilities. Regulatory authorities may also require post-marketing testing, which can involve significant expense.
Governments or regulatory authorities may impose new regulations or other changes that could further delay or preclude regulatory approval 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:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Distribution of our products outside the United States also is subject to extensive government
regulation. These regulations vary by country, including the requirements for approvals or clearance to market, the time required for regulatory review and the sanctions imposed for violations. We will be required to obtain a CE mark extension from
European Union regulators for our platelet system, originally obtained by Baxter in 2002, by May 2007. In addition to European Union-level approval, we must obtain regulatory and reimbursement approvals in some individual European countries,
including France, Germany and England, to market our products. In addition, our customers in many countries must obtain regulatory approval to sell blood components treated with the INTERCEPT Blood System. The level of additional product testing
varies by country, but could take a long time to complete. Failure to obtain necessary regulatory approvals or any other failure to comply with regulatory requirements could result in lost product sales and profitability. </FONT></P> <P

<FONT FACE="Times New Roman" SIZE="2">immunotherapy platform technologies may not translate to demonstration of safety and efficacy in human clinical trials. A number of companies in the
pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advancing stages of clinical trials, even after promising results in earlier preclinical and clinical trials. In addition, regulators and investigators
may impose more stringent, time consuming and expensive clinical trial requirements than we might otherwise choose to pursue as a precondition to proceeding with clinical testing. It may take us or our collaborators several years to complete this
testing, and failure can occur at any stage of the process. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We do not know whether we or our collaborators will begin and conduct planned clinical trials
on schedule, if at all. Significant delays in clinical testing could materially impact our clinical trials. We also do not know whether planned clinical trials will need to be revamped or will be completed on schedule, if at all. Criteria for
regulatory approval in cancer and infectious disease 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 product candidates emerging from any successful trials would not reach the market for several years. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman"
SIZE="2">Regulatory delays can also materially impact our product development costs. If we experience delays in testing or approvals, our product development costs will increase. For example, we may need to repeat clinical trials to address
regulatory or clinical questions. We may also need to make additional payments to third-party investigators and organizations to retain their services. If the delays are significant, our financial results and the commercial prospects for our product
candidates will be harmed, and our ability to become profitable will be delayed. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="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 or animal data to support such claims. After regulatory
approval for the initial indications, further clinical trials 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"><FONT FACE="Times New Roman" SIZE="2">In
addition to the regulatory requirements applicable to us and to our products, there are regulatory requirements applicable to our prospective customers of INTERCEPT Blood System products, the blood centers that process and distribute blood and blood
products. Blood centers and others will likely be required to obtain approved license supplements from the FDA or European regulatory authorities before making available blood products processed with our pathogen inactivation systems to hospitals
and transfusing physicians. This requirement or regulators&#146; delays in approving these supplements may deter some blood centers from using our products. Blood centers that do submit supplements 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:18px;margin-bottom:0px"><FONT

received CE mark approval and regulatory approval in certain countries in Europe, we have no products that have received regulatory approval for commercial sale and are being marketed. Our product candidates are in various stages of development, and
we face the risks of failure inherent in developing medical devices and biotechnology products based on new technologies. Our product candidates 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. We must provide the FDA and international regulatory authorities with preclinical, clinical and

products in those countries. Further randomized clinical trials funded by third parties will be conducted in some European countries, such as the Netherlands. We expect to conduct many smaller scale experience trials with prospective customers in a
number of European countries. We expect that decisions to adopt the platelet system may be deferred until completion of the additional trials and experience studies in Europe. In certain countries, including England and Germany, the system must be
approved for purchase or use by a specific governmental or non-governmental entity or entities, such as the Paul Ehrlich Institute in Germany. In France, the platelet system has been approved for use by blood centers in treating platelets; however,
we do not expect to sell the platelet system to commercial customers until we have successfully completed certain experience studies. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">We completed our

report, we continue to expect that the FDA will require an additional Phase III clinical trial to evaluate the hemostatic efficacy and safety of the platelet system, using the Company&#146;s final commercial product design, as compared to
conventional platelets. We also understand that our reassessment of our previously completed Phase III clinical trial data will not be sufficient to address the apparent differences observed in that trial between the treatment groups in the category

Based upon an internal evaluation of the results to date from these additional research activities and after consulting with regulatory authorities, we initiated a new Phase I trial in 2006 in the United States using a modified red blood cell system
before potentially progressing to later-stage clinical trials. We are utilizing a manual processing system in the Phase I trial, which system is not in a commercially feasible form. A number of trial design, process and product design issues that
could impact efficacy, regulatory approval and market acceptance will need to be resolved prior to the initiation of further clinical trials and while those clinical trials are being conducted, including determining the appropriate design of
subsequent Phase II clinical trials, if deemed necessary, and Phase III clinical trials, and developing a commercially feasible red blood cell system, including disposables, hardware and software for implementing the process in blood collection
centers. These development initiatives may be costly and time consuming. Even if the project proceeds on course, we would not expect to initiate a Phase III trial for our red blood cell system prior to late 2008. A delay in completing such
activities could result in a delay in the timely progression to later stage 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

STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Baxter and we have licensed rights to commercialization of the platelet and plasma systems in Japan, China, Taiwan, South Korea, Vietnam, Thailand, and Singapore to
BioOne. BioOne is solely responsible for obtaining regulatory approvals, marketing and selling the platelet and plasma systems in those countries. We understand that Baxter is not intending to maintain its CE mark registration for the platelet
system after which time regulatory responsibility will have passed to us. In addition, we have applied for CE mark approval of the plasma system independently from Baxter, and Baxter is not intending to apply for a CE mark for the plasma system.
However, BioOne is dependent on Baxter for the manufacture and supply of the platelet and plasma systems well beyond the time when Baxter intends to let its CE mark registration for the platelet system lapse. BioOne is also dependent on Baxter for
providing certain regulatory support and the timely transition of regulatory files and dossiers. BioOne may be unable to qualify the platelet and plasma systems for sale in certain countries in its territory in the absence of CE marks being held by
Baxter. BioOne has made only limited progress to date in commercializing the platelet and plasma systems in Asian territories. Because we only have a minority investment interest in BioOne, we lack the ability to significantly influence BioOne, and
are dependent on BioOne&#146;s performance to realize milestone and royalty revenue from commercialization of our platelet and plasma systems in those countries. In Japan, regulatory authorities may require our platelet and plasma systems to be
widely adopted commercially in Europe or approved by the FDA before it is considered for approval in Japan, which would delay or prevent BioOne from achieving significant product sales. There is no assurance that BioOne will be able to attract
additional required capital to successfully commercialize those products licensed from Baxter and us. BioOne is contractually obligated to pay us a milestone payment of cash and equity upon our receipt of CE mark approval for the plasma system in
Europe. If BioOne does not pay us the milestone on a timely basis, rights to the plasma system in BioOne&#146;s territories would revert to us. A return of our rights to the plasma system in the BioOne territories would likely depress the value of
BioOne&#146;s equity and may give rise to an impairment in the carrying value of our equity interest in BioOne. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B><I>Our vaccine programs are in an early
stage of development. </I></B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Our vaccine programs are in an early stage of development and there is a high risk of failure. We will be required to perform
extensive preclinical and clinical testing before any product candidate can be submitted for regulatory approval prior to commercialization. Clinical testing is very expensive, takes many years, and the outcome is uncertain. Failure to demonstrate
the safety or efficacy of a product candidate in preclinical studies or clinical trials would delay or prevent regulatory approval of that product candidate. Our potential vaccine products must meet rigorous testing standards in order to advance to
clinical testing. No product candidates employing either our <I>Listeria</I> or our KBMA platform technologies have been tested in humans, and preclinical data in animal studies and from <I>in vitro</I> experiments may not be predictive of clinical
safety and efficacy once product candidates are tested in humans. Our immunotherapy product candidates are unlikely to be used as single agents for the treatment of cancer or infectious diseases, but rather in combination with other drugs and
treatment regimens. Testing our vaccines in combination with other drugs and treatment regimens in clinical trials will introduce additional clinical, timeline and regulatory risks and complexities, including added expense, delay in conducting
clinical trials and uncertain regulatory requirements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Naturally-occurring <I>Listeria</I> is a bacterium that is a human pathogen that can cause serious
illness. Our immunotherapy product candidates for cancer indications use proprietary, modified strains of <I>Listeria</I> that are designed to have a substantially reduced ability to cause illness in humans. However, before our vaccine candidates
can be accepted for clinical testing, we must successfully complete a number of preclinical safety studies. We may not be able to identify a dose range in which our product candidates are therapeutically effective and yet maintain adequate safety
margins. We have filed an IND for our first vaccine candidate, CRS-100, and have obtained clearance from FDA to proceed with a Phase I, dose-escalation clinical trial. We have received approval from the institutional review boards, or IRB&#146;s, at
participating clinical sites, which is a predicate to enrolling subjects in the Phase I trial, and clinical investigators are in the process of enrolling eligible patients in the clinical trial. These investigators may encounter difficulties in
enrolling suitable patients in our trials, which may contribute to delays and increased costs in completing the Phase I trial. Clearance of a Phase I clinical trial using CRS-100 does not imply concurrence by FDA to our conducting later stage
studies with CRS-100 and does not imply clearance for clinical trials of our other <I>Listeria </I>vaccine candidates expressing antigens, such as CRS-207. Because CRS-207 and our other preclinical product candidates using <I>Listeria</I> rely on
the same base strain of <I>Listeria</I> used in CRS-100, any adverse findings in clinical trials of CRS-100 would likely adversely effect our ability to develop and test these other product candidates in human clinical trials. Our Phase I clinical
trial for CRS-100 involves testing in a patient population with advanced disease. We may be unable to test CRS-100 and our other product candidates in subsequent trials in patient populations that we believe may be better suited clinically or
commercially to our vaccines. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Because our vaccine candidates use novel platforms, the FDA or foreign regulators may require studies that we have not
anticipated. In addition, we have contracted with third-party manufacturers to produce our vaccines for research, preclinical and clinical testing. We have manufactured CRS-100 for toxicology studies and Phase I clinical trials, but have not engaged
in scale-up of the manufacturing process or the development of a commercial formulation. We also rely on third parties to conduct aspects of preclinical and clinical development on our behalf, including contract manufacturing and research services.
These third parties may encounter delays, over which we have significantly less control than research and development activities performed in-house, or experience unexpected results. We may experience numerous unforeseen events during, or as a
result of, the preclinical research and development process that could delay or prevent clinical testing, regulatory approval and commercialization of our potential products. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT

and uncertain. To date, we have relied not only upon internal scientific, development and financial resources, but also upon third parties. We have licensed our <I>Listeria</I> platform to MedImmune for use in developing a product candidate
potentially applicable to cancers expressing EphA2, a proprietary antigen owned by MedImmune. We are collaborating with investigators at Johns Hopkins University on other cancer and infectious disease programs. We also rely on advice and insights
from our scientific advisory board, a group of independent clinicians, professors and investigators, regarding our research and development activities. These relationships provide us with external perspectives and independent validation that may be
critical to our future success. Loss of these relationships or failure to attract others may result in additional expense, delays in development and regulatory approval and failure to commercialize products. We have received significant funding from
United States government agencies for research and development in both cancer and infectious disease, as well as funding from MedImmune under our license agreement relating to development of MEDI-543 (EphA2). Due to budgetary constraints, funding
from the Federal government, particularly funding from the Department of Defense and National Institutes of Health, is expected to be reduced from prior years and is subject to political and economic forces beyond our control. Additionally, we no
longer are deemed to be a small business for purposes of being eligible for certain grants administered by the National Institutes of Health and regulated by Small Business Administration. Federal funding in support of our programs to develop
prophylactic vaccines against anthrax and tularemia is not expected to lead to substantial commercial opportunities beyond potential biodefense applications, and we cannot be certain that the research conducted into those two infectious diseases
will readily translate into applications with greater commercial potential. Loss of funding from government sources and third parties would require us to reduce the scope of our research and development efforts in immunotherapeutics, narrowing the
number of programs to those we could support through internal resources. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B><I>If our competitors develop and market products that are more effective than

ability to respond quickly to medical and technological changes brought about by the development and introduction of new products. Product development is risky and uncertain, and we cannot assure you that we will develop our products successfully.
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"><FONT FACE="Times New Roman"
SIZE="2">Several companies 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. In Europe, several companies, including Grifols, Octapharma AG and Maco Pharma International GmbH, are developing or have developed commercial pathogen
inactivation systems to treat fresh frozen plasma. Navigant Biotechnologies, a wholly owned subsidiary of Gambro Group, is developing a pathogen inactivation system for blood products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
FACE="Times New Roman" SIZE="2">New methods of testing blood for specific pathogens have been approved by the FDA and in Europe, as have tests for bacteria in platelets. Continued delays in commercialization of the platelet system in France and
Germany may impact our ability to compete with bacterial testing for platelets. Tests have recently been approved to detect West Nile Virus in blood products. Other groups are developing rapid, point-of-care bacterial tests, synthetic blood product
substitutes and products to stimulate the growth of platelets. Development and commercialization of any of these or other related technologies could impair the potential market for our products. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">There are many companies pursuing programs for the treatment of cancer and treatment and prevention of infectious disease. Some are large pharmaceutical companies, such
as Pfizer, GlaxoSmithKline, Sanofi-Aventis, Bristol-Myers Squibb, Genentech and Gilead, which have greater experience and resources in product development, preclinical testing, human clinical trials, obtaining FDA and other regulatory approvals and
in manufacturing and marketing new therapies. We are also competing with other biotechnology companies, such as Cell Genesys, Inc., Coley Pharmaceutical Group, and Dendreon Corporation that have cancer vaccine programs that are in more advanced
stages of development than ours. In addition, other companies are pursuing early-stage research and development of <I>Listeria</I>-based immunotherapies. If any of these companies&#146; products are shown to be more efficacious than ours, our
<I>Listeria</I>-based products may fail to gain regulatory approval or commercial acceptance. If these companies&#146; products fail in human clinical trials, we may be required to overcome more significant regulatory barriers prior to gaining

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 in later stage clinical trials or after a marketing approval has been received. 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. We maintain product liability insurance, but do not know whether the insurance will provide adequate coverage against potential liabilities.

Our development and general and administrative expenses have resulted in substantial losses each year since our inception, including net losses of $58.3 million in 2003, $31.2 million in 2004. However, in 2005, we realized a $22.1 million
nonrecurring gain associated with the restructuring of a loan payable. As a result of this gain, we recorded net income of $13.1 million in 2005. At September&nbsp;30, 2006, we had an accumulated deficit of approximately $314.4 million. Except for
the platelet system, which has received European CE mark approval, all of our products are in the research and development stage, and we have not received significant revenue from product sales. We have received substantially all of our revenue from
our agreements with our development partners and from federal research grants and cooperative agreements. We will be required to conduct significant research, development, clinical testing and regulatory compliance activities for each of these
products. We expect our losses to continue at least until more of our product candidates are commercialized and achieve significant market acceptance. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman"

SIZE="2">Our product development programs are capital-intensive. We may need to reduce or stop further investment in specific research and development or sales and marketing activities if we are unable to obtain additional capital or if any of our
development programs are determined by us to be economically unfeasible. A product or program may be determined to be uneconomic if the commercial opportunity is insufficient to justify the investment required to develop and market the product or
for other reasons. We expect that our spending in support of research, development and commercialization of the platelet and plasma systems will be in excess of contribution from product sales, milestone payments and development funding for such
programs from third parties over the next year. We have recently elected to re-enter clinical trials for the red blood cell system with only partial funding from governmental sources. In addition, the February 2006 restructuring agreement with
Baxter requires that we take on more operational and financial responsibility for the commercialization of the platelet and plasma systems, particularly in Europe. As a result of these factors, further product development and commercialization of
the INTERCEPT Blood System may take longer and be more expensive than we previously anticipated. We expect to continue to spend substantial funds for our operations for the foreseeable future. Our cash, liquidity and capital requirements will depend
on many factors, including the development progress and costs of our programs, payments from collaborators, funding from agencies of the United States government, costs related to creating, maintaining and defending our intellectual property
position, regulatory approval and successful commercialization of our product candidates, competitive developments and regulatory factors. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">As of

tight Federal budgets, has led to a general decline in the amount of government funding. Additionally, we no longer are deemed to be a small business for purposes of being eligible for certain grants administered by the National Institutes of Health

former officers and directors are named as defendants in a purported securities class action lawsuit filed in the United States District Court for the Northern District of California. The lawsuit is brought on behalf of a purported class of
purchasers of our securities, and seeks unspecified damages. In addition, our directors and certain of our current and former officers have been named as defendants in a derivative lawsuit in the Superior Court for the County of Contra Costa,
California, which names Cerus as a nominal defendant. The plaintiff in this action is a Cerus stockholder who seeks to bring derivative claims on behalf of Cerus against the defendants. The lawsuit alleges breaches of fiduciary duty and related
claims. On August&nbsp;31, 2006, we announced that we had reached agreements to settle the outstanding class action and derivative lawsuits. Pursuant to the terms of the settlement agreements, the plaintiffs agreed to provide the defendants with a
release of all claims related to such class action and derivative lawsuits without any admission of wrongdoing or liability by any party. Under these settlement agreements, the total cash settlements will be funded entirely by insurance carriers
under our directors&#146; and officers&#146; liability insurance policy and will have no financial impact on Cerus. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">The settlement shall become effective
upon the satisfaction of a number of conditions, including, among others, the approval of the settlement by the courts, and the final and non-appealable entry of a judgment by the courts dismissing the class action and derivative lawsuits with
prejudice. We cannot predict when, if ever, the settlement will become effective. As with any litigation proceeding, we cannot predict with certainty the eventual outcome of pending litigation or likelihood that the proposed settlement will become
effective. If the settlements do not become effective, we may have to incur substantial expenses in connection with these lawsuits and in the event of an adverse outcome, our business could be harmed. </FONT></P> <P

conclude in future periods that we have effective internal controls over financial reporting in accordance with Section&nbsp;404 of the Sarbanes-Oxley Act of 2002. If we cannot favorably assess, or our independent registered public accountants are
unable to provide an unqualified attestation report on our assessment of, the effectiveness of our internal controls over financial reporting, investor confidence in the reliability of our financial reports may be adversely affected, which could
