Principles Board Opinion No. 25, including Interpretation No. 44, &#147;Accounting

required by FAS 123, and has been determined as if Cerus had accounted for its
employee stock options and employee stock purchase plan under the fair value
method of FAS 123. The fair value for these options and shares was estimated at
the date of grant using a Black-Scholes model with the following
weighted-average assumptions for the three months ended March 31, 2003 and
2002, respectively: the expected volatility was 0.866 and 0.637 and the
risk-free interest rate was 2.62% and 2.80%. The expected life of the option
was five years for the stock option plans for both periods and six months for
the employee stock purchase plan for both periods.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options that have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because Cerus&#146; employee stock options and purchased shares have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value estimate,
in management&#146;s</font></p>

standards as comprehensive income (revenue, expenses, gains and losses) be

other financial statements. Cerus does not have material components of other
comprehensive income. Therefore, comprehensive loss is equal to net loss for

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Development funding revenue includes amounts recognized under
agreements with Baxter Healthcare Corporation, the National Marrow Donor
Program, Kirin Brewery Company, Ltd. and the Consortium for Plasma Science.
Baxter and the Consortium are related parties to Cerus. Revenue from related
parties for the three months ended March 31, 2002 was $2,000. Development
funding revenue is recognized as the related project costs are incurred.
Research and development expenses are recognized as 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. There was no
milestone revenue recognized in the three months ended March 31, 2003 and 2002.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are developing medical systems and therapeutics based on our
proprietary Helinx</font><font face="Symbol" style="font-family:Symbol;">&#210;</font> technology for
controlling biological replication. Our most advanced programs are focused on
systems to enhance the safety of blood products used for transfusion. The
INTERCEPT Blood System, based on our Helinx technology, is designed to
inactivate viruses, bacteria, other pathogens and white blood cells. We also
are pursuing therapeutic applications of Helinx technology to treat and prevent
serious diseases.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are developing the INTERCEPT Blood System for platelets, plasma and
red blood cells with our development and commercialization partner, Baxter
Healthcare Corporation. The INTERCEPT Blood System targets and inactivates
blood-borne pathogens, such as HIV and hepatitis B and C, as well as harmful
white blood cells, while leaving intact the therapeutic properties of the blood
components. The INTERCEPT Blood System inactivates a broad array of pathogens
and has the potential to reduce the risk of transmission of pathogens for which
testing is not completely effective or is not currently performed. We believe that
the INTERCEPT Blood System also has the potential to inactivate new pathogens
before they are identified and before tests are developed to detect their
presence in donated blood.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In 2002, the INTERCEPT Blood System for platelets received CE Mark
approval and was commercially launched in Europe. The system also received
approval for use with buffy coat platelets in Canada in 2002. Cerus and Baxter
have submitted regulatory applications seeking marketing approval in Australia
and have begun the regulatory submission process to obtain approval in the
United States. The companies are in late stage development of the INTERCEPT
Blood System for plasma and red blood cells. Our allogeneic cellular immune therapy
(ACIT) program, designed to improve the outcome of bone marrow transplantation
procedures through use of T-cells treated with the Helinx technology, and
Epstein-Barr virus (EBV) cellular vaccine program are in Phase I clinical
trials.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Since our inception in 1991, we have devoted substantially all of our
efforts and resources<i><font style="font-style:italic;">  </font></i>to the research, development and clinical
testing of medical systems based on our Helinx technology.&#160; We have been unprofitable since inception
and, as of March 31, 2003, had an accumulated deficit of approximately $247.4
million. Except for the INTERCEPT Blood System for platelets, which is approved
for sale in Europe, all of our product candidates are in the research and
development stage, and we have not yet received significant revenue from
product sales. Cerus and Baxter must conduct significant research, development,
pre-clinical and clinical evaluation, commercialization and regulatory
compliance activities on these 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 and Baxter&#146;s ability to successfully complete development
and obtain additional regulatory approvals and on Baxter&#146;s ability to
commercialize and achieve market acceptance of the INTERCEPT Blood System. We
may never achieve a profitable level of operations. Further, under the
agreements discussed below, Baxter provides significant funding for development
of the INTERCEPT Blood System, based on an annual budgeting process, and is
responsible for manufacturing and marketing the products following regulatory
approvals. These agreements may be modified or terminated.</font></p>

increased 64% to $169,000 for the three months ended March 31, 2003 from
$103,000 for the comparable period in 2002. The change was due to increased

171% to $1.1 million for the three months ended March 31, 2003 from $0.4
million for the comparable period in 2002. The change was primarily due to
increased research activities funded by the second cooperative agreement
awarded in September 2002 and the timing of external contract research

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, pre-clinical safety studies, compound manufacturing and other
laboratory studies. Research and development expenses increased 23% to
$14.7 million for the three months ended March 31, 2003 from $11.9 million for
the comparable period in 2002. The change was primarily due to increased
development spending at Baxter for late-stage design and development of the
INTERCEPT Blood System.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our total research and development costs included $12.9 million for the
INTERCEPT Blood System and $1.8 million for all other programs for the three

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We anticipate that our research and development expenses will continue
to increase as additional regulatory approval filings are prepared and
additional product configurations and testing are completed for the platelet
and plasma systems, product design and Phase III clinical trials of the
INTERCEPT Blood System for red blood cells continue and research and
development activity relating to other clinical and pre-clinical programs
increases. Due to the inherent uncertainties and risks associated with
developing biomedical products, including but not limited to intense and
changing government regulation, uncertainty of future pre-clinical and clinical
study results and uncertainty associated with manufacturing, it is not possible
to reasonably estimate the costs to complete these research and development
projects. We face numerous risks and uncertainties associated with the
successful completion of our research and development projects; see &#147;Risk

of $0.7 million for the comparable period in 2002. We received proceeds from a
$50.0 million loan from Baxter Capital Corporation in January 2003 and recorded
$1.4 million of related interest expense for the three months ended March 31,
2003. Interest income from investments was $0.4 million for the three months
ended March 31, 2003 compared to $0.7 million for the comparable period in
2002. The decrease in interest income was primarily due to reduced investment
balances carried in 2003 and less favorable yields on investments as a result
of a decline in interest rates. We expect to earn interest at market rates in
proportion to the balances we maintain.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our sources of capital to date have consisted of public offerings and
private placements of equity securities, the loan from Baxter Capital
Corporation, payments received under our agreements with Baxter, Kirin, the
NMDP and the Consortium, United States government grants and cooperative
agreements and interest income. To date, we have not received significant
revenue from product sales, and we will not derive significant revenue from
product sales unless and until one or more products under development receives
regulatory approval and achieves market acceptance.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">At March 31, 2003, we had cash, cash equivalents and short-term
investments of $96.4 million. Net cash used in operating activities was $18.0
million for the three months ended March 31, 2003, compared to $14.2 million
for the same period in 2002, resulting primarily from the net loss of $17.2
million during the period and changes in other operating balances. Net cash
provided by investing activities during the three months ended March 31, 2003
of $0.7 million resulted principally from the sales and maturities of $41.1
million of short-term investments, offset by the purchases of $40.3 million of
short-term investments and $0.1 million of furniture, equipment and leasehold
improvements. Working capital increased to $85.6 million at March 31, 2003 from
$50.5 million at December 31, 2002, primarily due to the receipt of $50.0
million loan proceeds from Baxter Capital Corporation in January 2003. No
repayment of principal and interest on the loan is due until January 2008.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Working capital is calculated by deducting current liabilities of $14.6
million at March 31, 2003 and $16.8 million at December 31, 2002 from current
assets of $100.2 million at March 31, 2003 and $67.2 million at December 31,
2002. We believe that working capital provides a clear picture of the net
assets available to meet short-term capital needs.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We believe that our available cash balances, together with anticipated
cash flows from existing development and grant arrangements, will be sufficient
to meet our capital requirements until at least mid-2004. These near-term
capital requirements are dependent on various factors, including the
development progress and costs of the INTERCEPT Blood System and other
programs; payments to or from Baxter and the United States government; and
costs related to creating, maintaining and defending our intellectual property
position. 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, regulatory approval and successful commercialization of the INTERCEPT
Blood System and other product candidates, competitive developments and
regulatory factors. If Baxter were to terminate its agreements with us, we
might not be able to meet our long-term capital requirements. Future capital
funding transactions may result in dilution to our investors, and may not be
available on favorable terms or at all. In August 2001, we filed a shelf
registration statement on Form S-3 to offer and sell up to $300 million of
common stock and/or debt securities. We have no current commitments to offer or
sell securities pursuant to this registration statement.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Except for the INTERCEPT Blood System for platelets, which is approved
for sale in Europe and Canada, we have no products that have received
regulatory approval for commercial sale. 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
products must satisfy rigorous standards of safety and efficacy before the
United States Food and Drug Administration and international regulatory
authorities can approve them for commercial use. Our INTERCEPT Blood System and
stem cell transplantation programs are undergoing clinical testing. We must
provide the FDA and foreign regulatory authorities with pre-clinical, clinical
and manufacturing data that demonstrate our products are safe, effective and in
compliance with government regulations before the products can be approved for
commercial sale.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In 2002, the INTERCEPT Blood System for platelets received CE Mark
approval in Europe. Our development and marketing partner, Baxter Healthcare
Corporation, will need to complete validation studies and obtain reimbursement
approvals in some individual European countries to market our products in those
countries. In certain countries, including the United Kingdom, France and
Germany, the system must be approved for purchase or use by a specific
governmental or non-governmental (such as the Paul Ehrlich Institute in
Germany) entity or entities in order for it to be adopted by a specific customer.
The level of additional product testing varies by country, but could take more
than six months to complete after CE Mark approval. We completed our Phase III
clinical trial of the INTERCEPT Blood System for platelets in the United States
in March 2001, but Baxter and we have not yet submitted all of the modules of
our pre-market approval application to the FDA. We have completed Phase IIIa
and Phase IIIb clinical trials of the INTERCEPT Blood System for plasma in the
United States and are conducting a Phase IIIc clinical trial. We are conducting
Phase III clinical trials of INTERCEPT red blood cells in the United States.
Our allogeneic cellular immune therapy (referred to as ACIT) program, designed
to improve the outcome of bone marrow transplantation procedures through use of
T-cells treated with the Helinx technology, is in Phase I clinical trials in
the United States. Last, our Epstein-Barr virus (referred to as EBV) cellular
vaccine program is in a Phase I clinical trial in the United States. We will
have to conduct significant additional research and pre-clinical (animal) and
clinical (human) testing before we can file additional applications for product
approval with the FDA and foreign regulatory authorities. Clinical trials in
particular are expensive and have a high risk of failure. In addition, to
compete effectively, our products must be easy to use, cost-effective and

failure can occur at any stage of testing. 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. Pre-clinical and
clinical data can be interpreted in different ways, which could delay, limit or
prevent regulatory approval. Negative or inconclusive results from a
pre-clinical study or clinical trial or adverse medical events during a
clinical trial could cause a pre-clinical 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. The FDA has requested additional analyses of data from our United

market before we do. Some of our clinical trials involve patient groups with
rare medical conditions, which has in the past made, and may continue to make,
it difficult to identify and enroll a sufficient number of patients to complete
the trials on time. Our Phase III clinical trials of the INTERCEPT Blood System
for red blood cells involve patient groups that include a significant
percentage of children, which has made, and may continue to make, it difficult
to obtain consent to enroll these patients in our trials. Other factors,
including the unavailability of blood products or delays in the supply of
clinical product material, could also delay our clinical trials. Clinical
trials of our ACIT and EBV vaccine programs are sponsored by other
organizations, which will further reduce our ability to control the progress of
these trials. Our product development costs will increase if we have additional
delays in testing or approvals.</font></p>

our potential revenue would be delayed or diminished and our competitors may be
able to bring products to market before we do. The system disposables and
instruments we use in our pre-clinical studies and clinical trials are
prototypes of those to be used in the final products. As a result, we plan to
perform studies, both pre-clinical and clinical, to demonstrate the
acceptability of the commercial configuration and the equivalence of the

require us to perform additional studies, both pre-clinical and clinical, using

successfully commercialize our products will depend in part on the availability
of adequate reimbursement for product costs and related treatment of blood
components from governmental authorities and private health care insurers
(including health maintenance organizations), which are increasingly attempting
to contain health care costs by limiting both the extent of coverage and the
reimbursement rate for new tests and treatments. In addition, our products do
not inactivate all known pathogens, and the inability of our systems to
inactivate certain pathogens may inhibit their acceptance. 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; space and staffing requirements and require significant
capital investment. If our products fail to achieve market acceptance, we may

viruses, bacteria and other pathogens in platelets have focused almost entirely
on apheresis platelets collected on Baxter&#146;s automated collection platform.
Apheresis platelets are platelets that are collected from a single donor using
an automated collection machine. Currently, we estimate that the majority of
platelets used in the United States are collected by apheresis, with the
remainder prepared from pooled random donor platelets. Blood centers in the
United States preparing random donor platelets may be reluctant to switch to
apheresis collection, and the FDA may require us to make our systems to
inactivate viruses, bacteria and other pathogens in platelets compatible with
random donor platelets. In order to develop a platelet pathogen inactivation
system compatible with random donor platelets, we will need to perform
additional product development and testing, including clinical trials. These
development activities would increase our costs</font></p>

limit the time from pooling to transfusion to four hours to minimize the
proliferation of bacterial contamination in the pooled product. As a result,
most pooling occurs in hospitals. Our platelet system is designed for use in
blood centers, not at hospitals, and is intended to permit storage and
transfusion of treated platelets for up to five days after pooling. The FDA&#146;s
time limit between pooling and transfusion currently precludes the use of our
system with pooled random donor platelets. Although our system is designed to
reduce the risk of bacterial contamination, we cannot predict whether the FDA
would remove this process time constraint to allow our system to be used with
pooled random donor platelets, and we have not yet made a formal request for

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Baxter is one of three primary manufacturers of equipment for the
collection of apheresis platelets in the United States. The equipment, design
and materials used to collect the platelets vary from manufacturer to
manufacturer. We have conducted our pre-clinical and clinical studies in the
United States for apheresis platelets collected using only Baxter&#146;s equipment
and materials. Under an agreement with
Haemonetics Corporation, Baxter has agreed to provide Haemonetics with a
platelet storage solution proprietary to Cerus and Baxter, with the objective
that platelets collected on certain future Haemonetics apheresis collection
equipment may be directly treated using our platelet system. Baxter and
we also are adapting our platelet system to allow compatibility with other
manufacturers&#146; equipment. Such adaptations will require additional product
development and testing, including clinical trials. These development
activities will increase our costs significantly, and may not be successful.
Market acceptance of the platelet system in the United States may be delayed
until the system receives regulatory approval for use on such other equipment.</font></p>

whole blood using a semi-automated process known as the buffy coat process. For
platelets prepared by the buffy coat process, our platelet system is approved
for use only with Baxter&#146;s platelet collection and pooling materials. As a
result, market acceptance in Europe of our platelet system for platelets
prepared by the buffy coat process will depend on market acceptance of Baxter&#146;s
platelet collection and pooling sets or on our ability to develop products
compatible with other manufacturers&#146; platelet collection and pooling sets. Our
platelet system is also approved in Europe for use with Baxter&#146;s apheresis
collection equipment as well as the apheresis collection equipment of two other
manufacturers through the use of preparation kits.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In Canada, our platelet system is approved for use with platelets
prepared by the buffy coat process. Blood centers in Canada currently use the platelet
rich plasma and single donor collection methods, and do not use the buffy coat
process. The primary difference between the methods is the centrifugation
process for separating the component from whole blood to obtain a therapeutic
dose of platelets. Baxter and we intend to apply for the license to use the
platelet system in Canada with single-donor platelets. We will not have product
sales in Canada unless we apply for and receive approval for our system in
Canada for use with single-donor platelets or Canadian blood centers implement
the buffy coat method.</font></p>

the United States, the American Red Cross collects and distributes
approximately 50% of the nation&#146;s supply of blood and blood components. Other
major United States blood collection organizations include the New York Blood
Center and United Blood Services, each of which distributes approximately 6% of
the nation&#146;s supply of blood and blood components. In many countries of 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, the United Kingdom and France. Decisions on
product adoption are centralized in the United Kingdom and France. In Germany,
decision on product adoption is expected to be on a blood center-by-blood

will make the decision. The neutral party may not decide in our best interest.
Under the agreements, Baxter may independently develop a pathogen inactivation
system for fresh frozen plasma using a pre-existing technology. Such an effort
by Baxter could create conflicts in our joint program for the development of a
pathogen inactivation system for fresh frozen plasma.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The FDA and other agencies in the United States and in 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. The time
required for regulatory approvals is uncertain, and the process 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:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Even 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
practices. The failure to comply with these requirements could result in
enforcement action, which could harm our business. 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. Regulatory authorities may also require post-marketing testing, which
can involve significant expense. The government may impose new regulations 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:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">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. In
addition to CE Mark approval in Europe, we will need to obtain regulatory
approvals in individual European countries to market our products. The level of
additional product testing varies by country, but could take up to six months
or more to complete after CE Mark approval. Failure to obtain necessary
regulatory approvals or any other failure to comply with regulatory
requirements could result in reduced revenue and earnings. In some countries,
we may also need to obtain government approvals for reimbursement in order for
our product to be adopted. Reimbursement levels in some countries are
determined by annual budgeting processes which, in addition to affecting
product adoption, will affect the price we will be able to charge for our
products.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have conducted many toxicology studies to demonstrate our product
candidates&#146; safety, and we plan to conduct additional toxicology studies
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.
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 less compelling in light of improved safety
in the blood supply. In addition, our clinical development plan assumes that we
will not be required to perform human clinical studies to demonstrate our
systems&#146; ability to inactivate pathogens. Although we have discussed this plan
with the FDA and other regulatory authorities, they may find it unacceptable at
any time and may require human clinical trials to demonstrate efficacy in
inactivating pathogens. Trials of this type may be too large and expensive to
be practical.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Regulatory agencies may limit the uses, or indications, for which any
of our products are approved. For example, we believe that we 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:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition to the regulatory requirements applicable to us and to our
products, there are regulatory requirements applicable to our prospective
customers, 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 before using products processed with our
pathogen inactivation systems. This requirement or FDA 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:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Sales of our products may be affected by the availability of
reimbursement from governments or other third parties, such as insurance
companies. It is difficult to predict the reimbursement status of newly
approved, novel medical products. In certain foreign markets, governments have
issued regulations relating to the pricing and profitability of medical
products and medical products companies. There have been proposals in the
United States, at both the federal and state government level, to implement
such controls. The growth 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 Baxter and we can obtain for our products.</font></p>

net losses of $36.0 million in 2000, $49.4 million in 2001 and $57.2 million in
2002. As of March 31, 2003, we had an accumulated deficit of approximately $247.4 million. Except for our
platelet system, which is approved for sale in Europe, 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 Baxter and other 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 our product candidates are commercialized and achieve significant

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We expect our products to encounter significant competition. Our
products may compete with other approaches to blood safety and improving the
outcome of stem cell transplantation currently in use, as well as with future
products developed by biotechnology and pharmaceutical companies, hospital
supply companies, national and regional blood centers and governmental
organizations and agencies. Our success will depend in part on our ability to
respond quickly to medical and technological changes through 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.
Competitors or potential competitors may have substantially greater financial
and other resources than we have. They may also have greater experience in
pre-clinical testing, human clinical trials and other regulatory approval
procedures. Our ability to compete successfully will depend, in part, on our
ability to:</font></p>

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

for specific pathogens have recently been approved by the FDA, including tests
for bacteria. Several companies are developing tests for West Nile Virus in

remove psoralen compounds from blood products. We have reviewed the patent and
believe our work predates the invention disclosed in that patent. We are
continuing to review that patent and will make a determination as to whether
any action is necessary. Due to the extensive time required for development,

know-how or determine the scope and validity of others&#146; proprietary rights.
Patent litigation is costly. In addition, we may require interference

Litigation or interference proceedings could be expensive and time consuming,
and we could be unsuccessful in our efforts to enforce our intellectual

these agreements may be breached, we may not have adequate remedies for any
breach or our trade secrets may otherwise become known or be independently

is 12% per annum. No repayment of principal and interest is due until January
2008. The loan is secured with collateral based on future revenue from sales of
the INTERCEPT Blood System for platelets. Our substantial indebtedness will
result in a significant amount of interest expense in future periods. Our
indebtedness could have significant additional negative consequences, including
limiting our ability to obtain additional financing and to plan for, or

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The stock market has from time to time experienced extreme price and
volume fluctuations, which have particularly affected the market prices for
emerging biotechnology and medical device companies, and which have often been
unrelated to the operating performance of such companies. These broad market
fluctuations may adversely affect the market price of our common stock. In the
past, following periods of volatility in the market price of a company&#146;s stock,
securities class action litigation has occurred against the issuing company.
Such litigation could result in substantial costs and a diversion of
management&#146;s attention and resources, which could have a material adverse
effect on our revenue and earnings. Any adverse determination in</font></p>

and Procedures.</font></i> Our chief executive officer and chief
financial officer have concluded that Cerus&#146; disclosure controls and procedures
(as defined in Rules 13a-14(c) and 15d-14(c) promulgated under the Securities
Exchange Act of 1934, as amended) are sufficiently effective to ensure that the
information required to be disclosed by Cerus in the reports we file under the
Exchange Act is gathered, analyzed and disclosed with adequate timeliness,
accuracy and completeness, based on an evaluation of such controls and
procedures conducted within 90 days prior to the date hereof.</p>

There have been no significant changes in our internal controls or in other
factors that could significantly affect these controls subsequent to the date
of the evaluation referred to above, nor were there any significant
deficiencies or material weaknesses in Cerus&#146; internal controls. Accordingly,
no corrective actions were required or undertaken.</p>

on the Effectiveness of Controls.</font></i> A controls system, no matter how well conceived and operated, can
provide only reasonable, not absolute, assurance that the objectives of the
control system are met. Because of the inherent limitations in all control
systems, no evaluation of controls can provide absolute assurance that all
control issues, if any, within a company have been detected.</p>
