                         LARGE SCALE BIOLOGY CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.   THE COMPANY AND BASIS OF PRESENTATION

The Company

Large Scale Biology Corporation (formerly Biosource Technologies, Inc.) and its
subsidiaries (collectively the "Company") applies its proprietary and functional
genomics technologies to develop products and establish commercial
collaborations with pharmaceutical and other life science companies.

The Company was founded in 1987 to develop the GENEWARE(R) system, a viral-based
gene expression technology in plants, that enables the discovery, development
and production of new biopharmaceuticals and gene-based agricultural products.
The Company's proprietary systems are supported by patents, patent applications
and exclusive technology licenses.

In February 1999, the Company acquired 92.5% of Large Scale Proteomics
Corporation ("Proteomics," formerly Large Scale Biology) and its automated,
high-throughput ProGEX(TM) system which provides a snapshot of the protein
composition, or proteome, of cells and tissues, and is being used to rapidly
identify changes in proteins that are associated with diseases or with a
therapeutic effect.

On August 9, 2000, the initial public offering ("IPO") of the Company's common
stock was declared effective by the Securities and Exchange Commission (see Note
3).

The Company maintains its headquarters and a research facility in Vacaville,
California, a processing facility in Owensboro, Kentucky and an additional
research facility in Rockville, Maryland.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been
prepared by the Company in accordance with accounting principles generally
accepted in the United States of America for interim financial information and
with the instructions to Form 10Q and Article 10 of Regulation S-X of the
Securities and Exchange Commission. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of the Company's management,
all adjustments (consisting of only normal recurring adjustments) considered
necessary for a fair presentation have been included. The interim financial
information is not necessarily an indication of the results that may be expected
for the entire year.

The Condensed Consolidated Financial Statements include the accounts of Large
Scale Biology Corporation and its subsidiaries, including Proteomics, which was
92.5% owned by the Company from February 1999 until the remainder was acquired
in March 2000. All



                                        5

intercompany balances and transactions have been eliminated. The interim
financial information should be read in conjunction with the Audited
Consolidated Financial Statements and Notes thereto for the year ended December
31, 1999, included in the Company's Registration Statement on form S-1, as
amended (No.333-34198), which was declared effective by the Securities and
Exchange Commission on August 9, 2000.

Use of Estimates - The preparation of financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported revenue and expenses during the period. Actual
results could differ from those estimates.

Revenue Recognition - Revenues are derived from development agreements
consisting of research funding, technology access fees, milestone payments and
government grants. Research funding revenue is recognized as services are
performed and expenses are incurred. The Company's development agreements
generally provide for continued access by its partners to technologies developed
under such agreements over the life of the development agreement. As a result,
technology access fees and milestone payments received are deferred because
their receipt does not represent the culmination of the earnings process.
Revenue from technology access fees is recognized on a straight-line basis over
the remaining life of the development agreement. Revenue related to milestone
payments is recognized on a straight-line basis from the date of completion of
the specified milestone over the remaining life of the development agreement.
The life of a collaborative agreement is based on the terms of the agreement and
does not include renewal periods, unless renewal is assured. Upon renewal of an
agreement, the Company will account for any contract extension prospectively,
recognizing the related technology access fees and milestone payments in the
periods to which they relate. Grant revenue is recognized as expenses are
incurred and billed, except that revenue received for equipment purchases is
deferred and recognized as revenue as depreciation of the related equipment is
recorded.

Net Loss Per Share - Basic net loss per share is computed by dividing the net
loss for the period by the weighted average number of common shares outstanding
during the period. Diluted net loss per share is computed by dividing the net
loss for the period by the weighted average number of common shares and any
dilutive effect of potential common shares outstanding during the period.
Potentially dilutive securities with a weighted average number of shares of
7,938,471 and 9,624,178 for the three months ended September 30, 2000 and 1999,
respectively, and 11,168,632 and 9,110,817 for the nine months ended September
30, 2000 and 1999, respectively, composed of incremental common shares issuable
upon the exercise of stock options and warrants, and common shares issuable on
conversion of convertible preferred stock, were excluded from historical diluted
loss per share because of their antidilutive effect.

2.   ACQUISITION OF LARGE SCALE PROTEOMICS

During February 1999, Large Scale Biology Corporation acquired approximately
92.5% of the outstanding common stock of Proteomics in exchange for 2,287,634
shares of the Company's Series G convertible preferred stock and options to
purchase 60,562 shares of the Company's



                                        6
<PAGE>   9

common stock. This acquisition was accounted for by the purchase method of
accounting. The purchase price of $25,100,000 for this business combination was
based on the estimated fair value of the net tangible and intangible assets
received. The operating results of Proteomics are included in the consolidated
statement of operations of the Company effective February 1, 1999. In March
2000, the Company exercised its option to acquire the remaining 7.5% of the
outstanding common stock of Proteomics for $74,000.

The significant intangible assets acquired included in-process research and
development of $21,362,000 and core technology of $2,497,000. In conjunction
with its acquisition of the remaining 7.5% of Proteomics, the Company recorded
goodwill of $1,861,000, representing the excess of the carrying value of the
option and cash paid over the estimated fair value of the assets received and
liabilities assumed. The Company is amortizing the goodwill over three years.

Purchased research and development expense represents the value of purchased
in-process research and development projects that had not reached technological
feasibility at the date of acquisition. These projects relate to the development
of proteomics and virus technologies. The proteomics technology can only be used
for the large-scale, quantitative analysis and identification of proteins from
biological samples. There is no other known use of this technology for
performing analysis on other components of samples of biological origin (i.e.,
DNA, carbohydrates, lipids, etc.). Similarly, the virus technology is expected
to only be capable of separating virus-size particles - a size thought to be
unique to viruses. No alternative future uses or markets were identified for
these projects because of their unique qualities.

3.   INITIAL PUBLIC OFFERING AND CONVERSION OF PREFERRED STOCK

During the quarter ended September 30, 2000, the Company completed an initial
public offering of 5,750,000 shares of its common stock (including exercise of
the underwriters overallotment option) at a price of $17.00 per share. The
Company received net proceeds of approximately $89 million as a result of the
offering.

Upon the effectiveness of the Company's initial public offering, all 5,605,813
outstanding shares of the Company's convertible preferred stock with a stated
value of $40,497,000 were automatically converted into 8,441,415 shares of the
Company's common stock.

4.   STOCK COMPENSATION

On December 31, 1999, the Company issued to employees, officers and directors
options to purchase 1,545,000 shares of the Company's common stock. These
options are exercisable at between $6.67 and $7.50 per share, have a 10-year
life and vest in quarterly installments over 3 years. Deferred compensation in
the amount of $7,809,000 was recorded as the difference between the exercise
price and the estimated fair value of the common stock as of December 31, 1999.
During the three and nine months ended September 30, 2000, the Company
recognized $0.6 and $2.0 million, respectively, of expense related to the
amortization of deferred compensation. In December 1999, certain officers and
key employees were granted options to purchase 765,000 shares of the Company's
common stock at $7.50 per share which became exercisable upon the closing of the
Company's initial public offering. As a result, noncash



                                        7
<PAGE>   10

compensation expense of $7,268,000 was recognized during the quarter ended
September 30, 2000 based on the difference between the exercise price of those
options and the IPO price.

5.   DOW CONTRACT AND RELATED WARRANT

The Company entered into a Collaboration and License Agreement (the "Agreement")
with The Dow Chemical Company and its subsidiary Dow AgroSciences LLC
(collectively "Dow") on September 1, 1998. The Agreement provides funding for
sponsored genomics research, royalties upon product sales and payments when
certain milestones are achieved. The Company is entitled to all funding received
regardless of the results of the research. Accordingly, no obligation to repay
or repurchase technology has been recorded. Revenues from Dow represented 89%
and 85 % of total revenues during the three months ended September 30, 2000 and
1999, respectively, and 87% and 86% during the nine months ended September 30,
2000 and 1999, respectively. The contract is for three years and is renewable
annually after three years if mutually agreed to by Dow and the Company. The
contract provides for technology access fees of $10,000,000 in exchange for
access to the Company's technologies and a warrant to purchase 1,848,091 shares
of the Company's common stock, subject to certain vesting provisions. The fee
was allocated $1,392,000 to the warrant and $8,608,000 to deferred revenue based
on the estimated fair market value of the warrant. In addition, the Company
receives payments for meeting certain milestones under the Agreement. The access
fees are amortized to revenue over the life of the Agreement, and milestone
payments are amortized over the remaining term of the Agreement from the date
the milestone is achieved.

The warrant contained a put feature, whereby the Company was required to arrange
a private sale or repurchase the common stock at its fair value if the warrant
was exercised and the Company had not effected an initial public offering of its
common stock by December 31, 2008. The Company recorded the changes in fair
value of the warrants in its statement of operations until the effective date of
the Company's initial public offering on August 9, 2000, the date the put
feature expired.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATIONS

You should read the following discussion and analysis by our management of our
financial condition and results of operations in conjunction with our unaudited
condensed consolidated financial statements and the accompanying notes included
elsewhere in this report and the 1999 audited consolidated financial statements
and the accompanying notes included in our Registration Statement on Form S-1,
as amended (No. 333-34198), declared effective on August 9, 2000. This
Management's Discussion and Analysis of Financial Condition and Results of
Operations and other parts of this report contain forward-looking statements
that involve risks and uncertainties, such as statements of our plans,
objectives, expectations and intentions. Our actual results could differ
materially from those discussed in the forward-looking statements. Factors that
could cause or contribute to such differences include, but are not limited to
the factors discussed under "Factors Affecting Forward-Looking Statements"
below.

OVERVIEW

Large Scale Biology uses its proprietary proteomics and functional genomics
technologies, to develop products and establish commercial collaborations with
pharmaceutical, biotechnology, chemical and other life sciences companies, to
enable the transformation of proteomic and genomic information into multiple
product opportunities, such as drug targets, therapeutics and diagnostics for
drug effectiveness and toxicity.

Before February 1999, we were primarily engaged in the development and
commercialization of genomics technologies. In February 1999, we acquired 92.5%
of the outstanding common stock of Large Scale Proteomics ("Proteomics"), a
company primarily engaged in the development of proteomics technologies. In
March 2000, we acquired the remaining 7.5% of Proteomics' common stock. We used
the purchase method of accounting to record this acquisition.

We recognize revenues from our collaborative agreements, which typically provide
for research funding, technology access fees and milestone payments. We record
technology access fees and milestone payments as deferred revenue. We amortize
these technology access fees and milestone payments on a straight-line basis
over the remaining life of the related collaborative agreement. The life of a
collaborative agreement is based on the terms of the agreement and does not
include renewal periods, unless renewal is assured. Upon renewal of an
agreement, we will account for any contract extension prospectively, recognizing
the related technology access fees and milestone payments in the periods to
which they relate. We recognize research funding as we earn it.

In September 1998, we entered into a three-year collaboration and license
agreement (the "Agreement") with The Dow Chemical Company and its subsidiary Dow
AgroSciences LLC (collectively, "Dow"). The Agreement provides funding for
sponsored genomics research, royalties when Dow sells products that result from
this collaboration, technology access fees and payments when we reach specific
milestones. Revenues from the Agreement represented 89% and 85% of our revenues
during the three months ended September 30, 2000 and 1999,



                                        9
<PAGE>   12

respectively, and 87% and 86% or our revenues during the nine months ended
September 30, 2000 and 1999, respectively. We expect to recognize revenue of
$3.2 million and $8.4 million during the three months ending December 31, 2000
and year ending December 31, 2001, respectively, from the amortization of
deferred revenue of $11.6 million as of September 30, 2000 related to the
Agreement. In the event of the termination of the Dow contract, any deferred
revenue balances would be recognized as revenue as of the termination date. The
milestone and technology access fee payments under the Agreement are material to
the results of our operations. Should we receive additional milestone payments,
or if the term of the agreement is modified, the impact on revenue will be
dependent upon the nature of the additional payments and the modified term of
the Agreement. As a result, future revenues related to these payments and
operating margins could be materially higher or lower than previously reported.

During the third quarter of 2000, we raised net proceeds of approximately $89
million, including the exercise of the underwriters' overallotment option, as a
result of our Initial Public Offering ("IPO") which was declared effective on
August 9, 2000.

We have incurred significant losses in each year since our inception in 1987. As
of September 30, 2000, we had an accumulated deficit of $92.8 million. We expect
additional losses as we expand our research and development efforts, make
investments in strategic collaborations and enhance our technologies. Since our
IPO, we have begun the expansion of clinical studies for some of our products
under development and internally funded research projects. The resulting
increase in expenses could delay our profitability and result in increased
annual net losses.

RESULTS OF OPERATIONS

Three and Nine Months Ended September 30, 2000 and 1999

REVENUES. Revenues for the three months ended September 30, 2000 were $6.3
million, an increase of $2.2 million, or 55%, over the three months ended
September 30, 1999. Revenues for the first nine months of 2000 were $17.6
million, an increase of $7.3 million or 72% over the comparable period of 1999.
Revenues earned under the Agreement were $5.6 and $3.5 million in the three
months ended June 30, 2000 and 1999, respectively, and $15.3 and $8.8 million
for the nine months ended September 30, 2000 and 1999, respectively. The
increase in revenues from the Agreement was mostly attributable to amortization
of deferred revenue from milestone payments received after the first quarter of
1999.

Development agreement expenses. Development agreement expenses relate to
research activities incurred in connection with our collaborative agreements.
Development agreement expenses for the three and nine months ended September 30,
2000 were $2.6 and $6.4 million, respectively, an increase of $0.6 and $1.2
million, or 28% and 23%, respectively, over the comparable 1999 period. The
increase is primarily attributable to an increased level of research activity
under the Agreement. Research activities under the Agreement accounted for $2.2
and $5.3 million in the three and nine months ended September 30, 2000,
respectively, compared to $1.8 and $4.7 million in the three and nine months
ended September 30, 1999, respectively, of our development agreement expenses.
We expect that development agreement



                                       10
<PAGE>   13

expenses will increase if we are required to expand our work force and
facilities to meet commitments under any new collaborative agreements.

Research and development expenses. Research and development expenses for the
three and nine months ended September 30, 2000 were $3.7 and $11.1 million, an
increase of $1.1 and $4.4 million, or 41% and 66%, respectively, over the
comparable 1999 periods. The increase was largely attributable to the addition
of research personnel and increases in research funding paid to third persons.
Also, the increase for the first nine months of 2000 is attributable to expenses
only being included after the date of the acquisition of Proteomics, February 1,
1999, resulting in nine months of expenses for 2000 versus eight months of
expenses for 1999. We anticipate that research and development expenses will
continue to increase as we make expenditures for clinical trials to develop
pharmaceutical products and internally fund research projects.

General, administrative and marketing expenses. General, administrative and
marketing expenses for the three and nine months ended September 30, 2000 were
$2.4 and $5.9 million, compared to $1.7 and $6.1 million, respectively, for the
comparable 1999 periods. The increase of 41% for the three months ended
September 30, 2000 compared to the comparable 1999 period relates to increased
patent costs and costs associated with our becoming a public company on August
9, 2000. The decrease in the nine months ended September 30, 2000 was the result
of a charge of $1.5 million during 1999 related to previously capitalized patent
costs. Offsetting this charge were increased general and administrative costs to
support expanded operations and Proteomics' expenses only being included after
the date of the acquisition of Proteomics, February 1, 1999, resulting in nine
months of expenses for 2000 versus eight months of expenses for 1999. We
anticipate that our legal and regulatory expenses related to our patents will
continue to increase as we file, prosecute and defend new and existing patents.
We also expect general, administrative and marketing expenses to increase as we
expand our infrastructure to accommodate our anticipated growth.

Purchased research and development expenses. Purchased research and development
expenses for the nine months ended September 30, 1999 were $21.4 million, which
represents a charge for in-process research and development acquired in
connection with our acquisition of Proteomics. We did not have purchased
research and development expenses in the nine months ended September 30, 2000.

Stock compensation bonus. The stock compensation bonus of $7.3 million for the
three and nine months ended September 30, 2000, is a noncash charge upon the
completion of our Initial Public Offering for the vesting of stock options which
we issued to certain key officers and employees in December 1999.

Amortization of goodwill and purchased intangibles. The amortization of goodwill
and purchased intangibles of $0.3 and $0.9 million for the three and nine months
ended September 30, 2000 and $0.2 and $0.5 million for the three and nine months
ended September 30, 1999 relate to our purchase of 92.5% of Proteomics in
February 1999 and the exercise of our option to purchase the remaining 7.5% in
March 2000. Amortization charges for these



                                       11
<PAGE>   14

assets will continue through 2004 and are expected to remain at approximately
$0.3 million per quarter through 2002.

Interest income (expense). Interest income increased to $0.8 and $1.1 million
for the three and nine months ended September 30, 2000, respectively, from $0.1
and $0.2 million for the comparable 1999 periods, due to the investment of the
proceeds from our IPO in August 2000.

Change in fair value of warrant. The noncash charge of $1.4 and $0.8 million for
the three and nine months ended September 30, 2000 related to the increase in
the fair value of warrants issued in connection with the Agreement, which had
put options through the effective date of our IPO.

Provision for income tax. Although we had a net loss of $34.7 million before
provision for income taxes for our year ended December 31, 1999, we had taxable
income for federal and state income tax purposes which we offset by our use of
federal and state net operating loss carryforwards. As a result, we incurred
alternative minimum taxes of $190,000. Taxable income in 1999 was primarily
because of taxable milestone payments under the Agreement and the charge for
in-process research and development which was not deductible for tax purposes.

LIQUIDITY AND CAPITAL RESOURCES

The increase in our annual need for funds reflects the expanding scope of our
research and development activities. On August 9, 2000, our IPO was declared
effective, and we subsequently received $89 million of net proceeds through
September 30, 2000, including the exercise of the underwriters overallotment
option. Prior to our IPO, we funded our operations through payments from our
collaborative agreements of $62.2 million, the sale of $48.5 million of our
equity securities, other income of $6.8 million and debt and warrant financing
of $9.1 million.

At September 30, 2000, we had cash and cash equivalents of $56.7 million and
marketable securities of $34.1 million. Net cash used in operating activities of
$10.0 million in the nine months ended September 30, 2000 was principally due to
$19.6 million paid to our suppliers and employees, partially offset by $6.8
million of research funding received under the Dow Agreement, $2.1 million from
other agreements and interest from our investments of $1.0 million. Maintenance
of positive net cash provided by operating activities will depend upon our
entering into new collaboration agreements and the level of internally funded
research and development activities.

Net cash used by investing activities of $30.1 million in the nine months ended
September 30, 2000 was principally due to $26.8 million net investment in
marketable securities, $2.2 million for purchases of property, plant and
equipment and $1.1 million for increases in intangible and other assets. We
anticipate that our capital expenditures will increase in the future to meet the
demands from new collaboration agreements and research and development efforts.
We may use a portion of our cash to acquire or invest in complementary
businesses, products or technologies, or to obtain the right to use such
complementary technologies.



                                       12
<PAGE>   15

Net cash provided by financing activities of $89.8 million in the nine months
ended September 30, 2000 was primarily the result of $90.2 million of proceeds
from our IPO and exercise of stock options, offset by $0.4 million of net
principal payments on long-term debt.

In the future, our liquidity and capital resources will depend upon, among other
things, the level of our research and development activities, development,
clinical, regulatory and marketing expenses and funding from our collaborations.
We believe that our cash and cash equivalents and our marketable securities,
together with revenues from our collaborations, research and development grants
and other sources will be adequate to fund our anticipated cash and working
capital requirements at least through December 31, 2002. During or after this
period, if our capital resources are insufficient to meet our future capital
requirements and expenses, we may need to sell additional equity or debt
securities or obtain additional credit arrangements. Additional financing may
not be available on terms acceptable to us or at all. The sale of additional
equity or convertible debt securities may result in additional dilution to our
stockholders.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. This statement
establishes accounting and reporting standards for derivative instruments and
hedging activities and is effective for us beginning in the first quarter of the
fiscal year beginning January 1, 2001. The statement requires balance sheet
recognition of derivatives as assets or liabilities measured at fair value.
Accounting for gains and losses resulting from changes in the values of
derivatives is dependent on the use of the derivative and whether it qualifies
for hedge accounting. We do not believe that the adoption of SFAS No. 133 will
have a material impact on our financial statements.

In December 1999, the SEC issued Staff Accounting bulletin No. 101, Revenue
Recognition in Financial Statements, or SAB 101. SAB 101 provides guidance on
the recognition, presentation and disclosure of revenue in financial statements
filed with the SEC. The Company believes that it complies with the provisions of
SAB 101.

INFLATION

We believe that inflation has not had a material adverse impact on our business
or operating results during the periods presented.

                  FACTORS AFFECTING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10Q contains forward-looking statements within the
meaning of the federal securities laws, which involve risks and uncertainties.
These forward-looking statements are not historical facts but rather are based
on current expectations, estimates and projections about our industry, beliefs
and assumptions. We use words such as "anticipates," "expects," "intends,"
"plans," "believes," "seeks," "estimates" and variations of these words and
similar expressions to identify forward-looking statements. These statements are
not guarantees of future performance and are subject to risks, uncertainties and
other factors, some of which are beyond our control, are difficult to predict
and could cause actual results to



                                       13

differ materially from those expressed or forecasted in the forward-looking
statements. These risks and uncertainties include those described below and
elsewhere in this Report. You should not place undue reliance on these
forward-looking statements, which reflect our management's view only as of the
date of this Report.

RISKS RELATED TO OUR BUSINESS

WE ARE AT AN EARLY STAGE OF DEVELOPMENT, AND WE MAY NOT BE ABLE TO SUCCESSFULLY
DEVELOP AND COMMERCIALIZE OUR PRODUCTS AND TECHNOLOGIES

We are in an early stage of development as an operating company, and we are
subject to all the risks inherent in the development of a business enterprise,
including the need for substantial capital to support the development of our
products and technologies. We have had limited revenue from contract research
and development services and collaborations. We are still developing our three
primary database programs, HPI, MAP and MED, that we intend to commercialize. We
have marketed a limited number of our own technologies. We have not yet operated
our ProGEx system on the large scale we believe will be necessary to complete
our HPI database and other proteomics projects. In addition, we are still in the
process of integrating our proprietary protein databases with information on
gene function. If we are unable to manufacture and operate our ProGEx system on
a large scale or to integrate our protein databases with information on gene
function, we may not be able to achieve our objectives in the field of
proteomics.

Our other anticipated products, including a novel vaccine for the treatment of
non-Hodgkin's lymphoma, most likely will require that we enter into new
collaborations before we can manufacture and market them, and are subject to the
governmental regulatory process. Because we are in new and developing fields,
and our research focuses on new and unproven technologies, our therapeutic
vaccines, drugs and proteins that we develop may not be effective in humans, or
may not meet regulatory requirements for safety and efficacy. In addition, even
if we successfully develop a product, there may not be a substantial commercial
market for that product.

WE ARE IN NEW AND DEVELOPING FIELDS AND THERE MAY NOT BE A MARKET FOR OUR
PRODUCTS AND TECHNOLOGIES

We focus our technologies on the new and developing fields of proteomics and
functional genomics. Our research is fundamentally unique and we cannot assure
the acceptance of its scientific merit, the benefits of products produced by it
or that the public will react favorably to it. Protein-based gene expression
products and technologies, including our plant-derived proteins and our ProGEx
system and GENEWARE technology, have limited commercial precedent. The
usefulness of the information and products generated by our proteomics and
functional genomics technologies is unproven, and our collaborators and
potential collaborators may determine that they are not useful or
cost-effective. In addition, we must develop these new products and technologies
in time to meet market demand, if any. If we fail to do so, it is likely that
other technologies and companies will predominate and we will not be able to
earn a sufficient return on our investment.



                                       14
<PAGE>   17

WE HAVE A HISTORY OF LOSSES AND CANNOT PREDICT WHEN WE WILL BECOME PROFITABLE,
IF AT ALL

We have had net losses in each year since our inception in 1987. We sustained a
net loss of approximately $34.9 million in 1999 and $14.0 million for the nine
months ended September 30, 2000 and had an accumulated deficit of approximately
$92.8 million as of September 30, 2000. Net cash flow provided by operating
activities was positive in 1999 due principally to payments under the Dow
Agreement, but we incurred substantial non-cash charges of $31.8 million in 1999
due principally to a non-recurring expense associated with the acquisition of
Large Scale Proteomics. Milestone payments from the Dow Agreement are expected
to be substantially lower in 2000, and we must enter into new collaborations,
with parties not yet identified, to make up for this decline in cash flows.
Additionally, we expect to spend significant amounts to fund research and
development and to enhance our core technologies. As a result, we expect that
our operating expenses will increase significantly and we will need to generate
significant additional revenues from collaborations and the commercialization of
our products and technologies to achieve profitability. We expect to incur
substantial losses for the foreseeable future. If we are unable to enter into
new collaborations, control our operating expenses and successfully
commercialize our products and technologies, we may never become profitable.

WE MAY REQUIRE ADDITIONAL CAPITAL

In order for us to remain competitive, we must continue to develop our databases
and improve our technologies, including our ProGEx system and GENEWARE
technology, improve our database software and develop or acquire new
technologies. We believe our cash and cash equivalents and our marketable
securities at September 30, 2000, together with revenues from our
collaborations, research and development grants and all other sources will be
sufficient to fund our operations for at least the next 24 months. However,
changes in our business may occur that would consume available capital resources
significantly sooner than we expect. If our capital resources are insufficient
to meet future capital requirements and expenses, we will have to raise
additional funds, which will decrease the value of our common stock. We may
raise this capital through public or private financings or additional
collaborations, strategic partnerships or licensing arrangements. If additional
capital becomes necessary in the future, it would likely amount to at least tens
of millions of dollars. If we are unable to raise sufficient additional capital,
we will have to curtail or cease operations.

ALTERNATIVE METHODS MAY SUPERSEDE OUR TECHNOLOGIES OR MAKE THEM NON-COMPETITIVE

The genomics and proteomics businesses are intensely competitive. The genomics
and proteomics industries are characterized by extensive research efforts which
result in rapid technological progress. If our competitors succeed in developing
products or technologies that are more effective than ours or that render our
products or technologies obsolete or noncompetitive, our business will suffer.
Many universities, public agencies and established pharmaceutical,
biotechnology, chemical and other life sciences companies with substantially
greater resources then we have are developing and using technologies and are
actively engaging in the development of products similar to or competitive with
our products and technologies. Our competitors are using proteomics and genomics
technologies to identify



                                       15
<PAGE>   18

potential drug targets, therapeutic proteins and diagnostic marker proteins. In
addition, our competitors have developed databases containing gene sequence,
gene expression, genetic variation or other genomic information and are
marketing or plan to market their data to pharmaceutical, biotechnology,
chemical and other life sciences companies. To remain competitive, we must
continue to invest in new and existing technologies, expand our databases and
improve our bioinformatics software, including proprietary software used with
our ProGEx system.

Our competitors may devise alternative methods to obtain proteomic and
functional genomic information more rapidly, more completely or with greater
accuracy than is achieved by using our ProGEx and GENEWARE systems. There has
been and continues to be substantial academic and commercial research effort
devoted to development of such alternative methods. If a successful replacement
method is developed, it could undermine the commercial basis for the products
and technologies we intend to provide.

WE MAY NOT BE ABLE TO ENTER INTO THE COLLABORATIONS NECESSARY TO FULLY DEVELOP
AND COMMERCIALIZE OUR PRODUCTS AND TECHNOLOGIES, AND WE WILL BE DEPENDENT ON OUR
COLLABORATORS IF WE DO

Although we intend to independently pursue some therapeutic product applications
into the development stage, we will develop and commercialize most of our
products only in collaboration with pharmaceutical, biotechnology, chemical and
other life sciences companies. Our success will depend in large part on our
ability to enter into future collaborations with other companies for the
research and development, pre-clinical and clinical testing and the regulatory
approval and commercialization of our products. Our reliance upon these
companies for these capabilities will reduce our control over such activities
and could make us dependent upon them. To date, we have entered into only a
limited number of collaborations. Generally, the scope of these collaborations
has been to demonstrate the function of plant genes and the feasibility of using
viral vectors to create proteins in plants and to identify the identifying
marker proteins for drug development. Our agreements provide us with rights to
participate in the commercial development of products resulting from the use of
our technologies. We may be unable to obtain such rights in future
collaborations. In addition, unforeseen delays or complications could arise and
result in the breach of our contractual obligations with our collaborators and
others, or render our technologies unable to perform at the quality and capacity
levels required for success.

THE NON-RENEWAL OR PREMATURE TERMINATION OF THE DOW AGREEMENT OR OUR OTHER
COLLABORATIONS COULD ADVERSELY AFFECT OUR REVENUES AND HARM OUR BUSINESS

In 1999 and for the nine months ended September 30, 2000, the Dow Agreement
accounted for approximately 88% and 87% of our revenues, respectively. The Dow
Agreement terminates on September 1, 2001. If Dow terminates this Agreement
before then, we may be unable to quickly replace such a large customer with
other sources of revenue, which would decrease our net revenues and might make
it difficult for us to execute our business plan. In addition, if in the future
our collaborations are similarly limited to a small number of major
relationships, the loss of any future major collaborative agreement could reduce
our revenue and delay or



                                       16
<PAGE>   19

terminate the potential development or commercialization of any of our products
or technologies.

CONFLICTS WITH OUR COLLABORATORS COULD HARM OUR BUSINESS

Conflicts with our collaborators could have a negative impact on our
relationships with them and impair our ability to enter into future
collaborations, either of which could adversely affect our business. Our
collaborators could develop competing products, preclude us from entering into
collaborations with their competitors or terminate their agreements with us
prematurely. Moreover, disagreements could arise with our collaborators over
rights to our intellectual property and our rights to share in any of the future
revenues from products or technologies resulting from use of our technologies,
or our activities in separate fields may conflict with other business plans of
our collaborators.

Dow owns or controls patent rights in the field of viral vectors covering the
infection of plants and the expression of foreign genes in plants, and has
informed us that it believes that some of our plant viral activities may fall
within the scope of these patents. If we are unable to resolve this matter, and
are found to have infringed upon these rights, our product development and
research activities related to plant viruses which fall within the scope of
Dow's patents may be delayed or terminated. These kinds of disagreements could
result in costly and time-consuming litigation and divert our financial and
managerial resources.

WE MUST ENTER INTO AGREEMENTS WITH THIRD PARTIES TO PROVIDE SALES AND MARKETING
SERVICES, OR DEVELOP THESE CAPABILITIES ON OUR OWN, IF WE ARE TO SUCCESSFULLY
COMMERCIALIZE OUR PRODUCTS AND TECHNOLOGIES

We have no sales or marketing force. Although we plan to enter into sales and
marketing arrangements with third parties, we may not be able to enter into
these arrangements on favorable terms, if at all. If we cannot enter into these
arrangements, we must develop a sales and marketing force with sufficient
technical expertise to generate demand for our products and technologies. Our
inability to develop or contract for effective sales and marketing capabilities
would significantly impair our ability to develop and commercialize our
products.

IF OUR STRATEGIC DECISIONS DO NOT YIELD COMMERCIALLY VIABLE PRODUCTS, WE MAY NOT
ACHIEVE PROFITABILITY

While our technologies may be applicable to multiple products in numerous
industries, due to our limited financial and managerial resources we have made
strategic decisions to pursue specific products in specific industries. This
requires us to forego opportunities in other products and industries. We may not
successfully select technologies or those genes or proteins with the most
potential for commercial development, or we may not successfully commercialize
any product based on our technologies or on genes or proteins that we discover.
Our efforts may not produce viable commercial products and we may lose other,
more profitable opportunities.



                                       17
<PAGE>   20

WE MAY NOT BE ABLE TO SUCCESSFULLY MANUFACTURE OUR PRODUCTS IN COMMERCIAL
QUANTITIES OR AT ACCEPTABLE COSTS

We have not yet commercially manufactured any products using our technologies,
including proteins manufactured with our GENEWARE technology. We have only
produced products on a small, test scale. The failure of our technologies to
provide safe, effective, useful or commercially viable approaches to the
discovery and development of drug targets and proteins which can be used as
therapeutic would significantly limit our business plan and future growth.

WE MAY NOT BE ABLE TO CREATE AND COMMERCIALIZE A COMBINED PROTEOME AND GENOMIC
SOURCE OF INFORMATION

We may not be able to successfully combine our proprietary protein data with
genomic information. Even if we are able to integrate information on gene
function with our proteomic databases, competing technologies may prove to be
more effective or efficient, which would limit or eliminate our revenue
opportunities. If we do not successfully create and commercialize a combined
proteome and genome source of information, it could reduce our revenues.

WE MAY BE UNABLE TO RECRUIT AND RETAIN OUR SENIOR MANAGEMENT AND OTHER KEY
SCIENTIFIC PERSONNEL ON WHOM WE ARE DEPENDENT

The loss of one or more of our senior management and other key scientific
personnel could have a material adverse effect on our business and could inhibit
our research and development and commercialization efforts. Although we have
entered into employment agreements with some of our key personnel, these
employment agreements are for a limited period of time and not all key personnel
have employment agreements. There is currently a shortage of skilled senior
management in the biotechnology industry, which is likely to continue and
intensify. In addition, we face competition for research scientists and
technical staff from other companies, academic institutions, government
entities, nonprofit laboratories and other organizations. Failure to recruit and
retain senior management and scientific personnel on acceptable terms would
prevent us from achieving our business objectives.

CATASTROPHIC DAMAGE TO ANY OF OUR FACILITIES COULD IMPAIR OUR BUSINESS

Our biological material and proprietary instrumentation and databases are
currently located at one of three facilities. If a facility suffered
catastrophic damage from a disaster, such as a fire, flood, earthquake, power
loss or similar event, we might lose important, or even unique, materials,
machinery, equipment and databases. Loss of such material, machinery, equipment
and databases could delay or impair our operations and our research. The
insurance we maintain which covers fire but not flood or earthquakes and
generally covers the cost of replacement of facilities and equipment, may not be
adequate to cover our losses resulting from disasters or other business
interruptions. In addition, the potentially unique nature of our materials,
instrumentation, databases and research activities could make it difficult for
us to recover quickly from a disaster, if at all.



                                       18
<PAGE>   21

CONCENTRATION OF OWNERSHIP AMONG OUR EXISTING EXECUTIVE OFFICERS, DIRECTORS AND
PRINCIPAL STOCKHOLDERS ENABLES THEM TO COLLECTIVELY CONTROL ALL SIGNIFICANT
CORPORATE DECISIONS

Following our IPO, our directors, our executive officers and entities affiliated
with our directors and our executive officers beneficially own, in the
aggregate, approximately 42.0% of our outstanding common stock. These
stockholders as a group will be able to elect our directors and officers,
control our management and affairs and be able to control most matters requiring
the approval of our stockholders, including any merger, consolidation or sale of
all or substantially all of our assets and any other significant corporate
transaction. The concentration of ownership will also prevent a change of
control of our Company at a premium price if these stockholders oppose it.

PROVISIONS OF OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY INHIBIT A TAKEOVER,
WHICH COULD ADVERSELY AFFECT OUR STOCK PRICE

Provisions in our charter and bylaws and applicable provisions of the Delaware
General Corporation Law may make it more difficult for a third party to acquire
control of us without the approval of our board of directors. These provisions
may make it more difficult or expensive for a third party to acquire a majority
of our common stock or delay, prevent or deter a merger, acquisition, tender
offer or proxy contest, which may adversely affect our stock price.

RISKS RELATED TO OUR INDUSTRY

IF COMPANIES IN THE PHARMACEUTICAL, BIOTECHNOLOGY, CHEMICAL AND LIFE SCIENCES
INDUSTRIES DO NOT SUCCEED OR THEIR DEMAND FOR OUR PRODUCTS AND TECHNOLOGIES
DECREASES, THEN OUR REVENUES COULD BE REDUCED

We expect to derive our revenues primarily from products and technologies
provided to the pharmaceutical, biotechnology, chemical and life sciences
industries. Accordingly, our success will depend directly on the success of the
companies in these industries and their demand for our products and
technologies. Our operating results may fluctuate substantially due to
reductions and delays in research and development expenditures by companies in
those industries, or their unwillingness or inability to use our products and
technologies. These reductions and delays may result from factors which are not
within our control, such as:

-   Changes in economic conditions generally

-   The extent to which companies in these industries conduct research and
    development involving proteomics and functional genomics in-house or through
    industry consortia

-   The extent to which genomic information is or is not made publicly available

-   Consolidation within one or more of these industries

-   Changes in the regulatory environment affecting these industries

-   Pricing pressures

-   Market-driven pressures on companies to consolidate and reduce costs

-   Other factors affecting research and development spending in these
    industries

IF COMPETITIVE PRODUCTS ARE BETTER THAN OUR PRODUCTS, THEN OUR BUSINESSES MAY
FAIL



                                       19
<PAGE>   22

The markets for protein development and production, including human and
veterinary therapeutics and vaccines like the ones we are developing, are highly
competitive. We believe that within the next year, virtually all of the genes in
the human genome will be identified. We face significant competition in our
protein product development and production efforts from entities using
alternative, and in some cases higher volume and larger scale, approaches for
the same purpose. Competitors with substantially greater resources, such as
Oxford Glycosciences Plc and Celera Genomics Group of P.E. Corp., are actively
developing products similar to or competitive with our products and potential
products. Our competitors may succeed in developing products or obtaining
regulatory approval before we do or in developing products that are more
effective than those we develop or propose to develop. A large number of
universities and other not-for-profit institutions, many of which are funded by
the U.S. and foreign governments, are also conducting research to discover
genes. Any one or more of these entities may discover and establish a patent
position in one or more of the genes or proteins that we wish to study.

In addition, several pharmaceutical, biotechnology, chemical and other life
sciences companies engage in research and development in the use of unique gene
expression systems to produce therapeutic proteins. These competitors may
develop products earlier than we do, obtain regulatory approvals faster than we
can or develop products that are more effective than ours. At least one of our
major competitors, Oxford Glyosciences, is located in Europe, and our ability to
use our patent rights to prevent competition in the creation and use of
proteomics-driven products and technologies is more limited outside of the
United States. New developments are expected to continue, and discoveries by
others may render our products and technologies noncompetitive, which could lead
to the failure of our business.

WE MAY NOT HAVE ACCESS TO SUFFICIENTLY COMPLETE, ACCURATE OR UNCONTAMINATED DATA
FROM OUTSIDE SOURCES, INCLUDING GENOME SEQUENCE DATA WHICH WOULD INCREASE OUR
COSTS AND COULD AFFECT OUR PRODUCT DEVELOPMENT EFFORTS

The efforts of the Human Genome Project and other private companies to create a
complete catalog of the human genome may fail or not be sufficiently complete to
enable us to fully integrate that data with our proprietary protein databases.
In addition, we obtain our data from other sources, including our academic
collaborators and our sources of cell and tissue samples. This data could
contain errors or other defects which could corrupt our databases or our data
sources may have acquired this information in a manner that violates various
applicable legal requirements.

WE AND OUR COLLABORATORS MAY NOT OBTAIN FDA AND OTHER APPROVALS FOR OUR PRODUCTS
IN A TIMELY MANNER, OR AT ALL

Drugs and diagnostic products are subject to an extensive and uncertain
regulatory approval process by the FDA and comparable agencies in other
countries. The regulation of new products is extensive, and the required process
of laboratory testing and human studies is lengthy, expensive and uncertain. The
burden of these regulations will fall on us to the extent we are developing
proprietary products on our own. We may not be able to obtain the clearances and
approvals necessary for the clinical testing, field-testing, manufacturing or



                                       20
<PAGE>   23

marketing of our products. If the products are the result of a collaborative
effort, these burdens may fall on our collaborators or we may share these
burdens with them. We may not obtain FDA or other approvals for those products
in a timely manner, or at all. We may encounter significant delays or excessive
costs in our efforts to secure necessary approvals or licenses. Even if we
obtain FDA regulatory approvals, the FDA extensively regulates manufacturing,
labeling, marketing, promotion and advertising after product approval. Further,
once a manufacturer obtains regulatory approval, a marketed product and its
manufacturer are subject to continual review, and discovery of previously
unknown problems with a product or manufacturer may result in restrictions on
the product, manufacturer and manufacturing facility, including withdrawal of
the product from the market. Finally, in some countries, regulatory agencies
also set or approve the sale prices for drug products. Additionally, several of
our product development areas may involve relatively new technology and have not
been the subject of extensive product testing in humans. The regulatory
requirements governing these products and related clinical procedures remain
uncertain and the products themselves may be subject to substantial review by
foreign governmental regulatory authorities that could prevent or delay approval
in those countries. Regulatory requirements ultimately imposed on our products
could limit our ability to test, manufacture and, ultimately, commercialize our
products.

IF NEW RULES ISSUED BY THE USDA ADVERSELY AFFECT OUR COLLABORATORS' ABILITY TO
COMMERCIALIZE GENETICALLY MODIFIED PRODUCTS, THEN OUR ABILITY TO SELL OUR
PRODUCTS AND TECHNOLOGIES WILL BE SEVERELY IMPAIRED

We must comply with USDA regulations for outdoor releases of genetically
engineered organisms as well as other products designed for use on or with
agricultural products. Recently, the USDA released new regulations that prohibit
the inclusion of genetically modified ingredients in products labeled as
organic. The USDA regulations also prohibit the use of genetically modified
fibers in clothing labeled as organic. These new regulations ultimately could
make our products under development with our collaborators, including Dow,
unattractive to or too expensive for consumers, or could cause the government to
prohibit their sale or use. In addition, the USDA prohibits growing and
transporting genetically modified plants except pursuant to an exemption or
under special permits. We may use genetically modified plants as screening or
production hosts. Changes in USDA policy regarding the movement or field release
of genetically modified plant hosts could adversely affect our business by
increasing the cost of our products and technologies or decreasing consumer
demand for those products and technologies or causing the government to prohibit
their sale or use.

FUTURE LEGAL AND REGULATORY REQUIREMENTS IMPOSED BY THE FDA MAY LIMIT OR
DISCOURAGE THE USE OF OUR GENETICALLY ENGINEERED ORGANISMS AND PRODUCTS, WHICH
COULD REDUCE OUR REVENUES

The FDA currently applies the same regulatory standards to foods developed
through genetic engineering as it applies to foods developed through traditional
plant breeding. However, genetically engineered food products will be subject to
pre-market review if these products raise safety questions or if the FDA
considers these products to be food additives. Our products and the products of
our collaborators that contain genes that we identify or determine to have a
particular function may be subject to lengthy FDA reviews and unfavorable FDA



                                       21
<PAGE>   24

determinations if they raise questions, if the FDA considers them to be food
additives or if the FDA changes its policy. Also, the FDA announced in a policy
statement that it will not require that genetically engineered agricultural
products be labeled as such, provided that these products are as safe and have
the same nutritional characteristics as conventionally developed products. The
FDA may reconsider or change its labeling policies, or local or state
authorities may enact labeling requirements. Any such labeling requirements
could reduce the demand for genetically engineered products. In those products
where production must be performed outdoors, the USDA prohibits manufacturers
from growing and transporting genetically engineered plants except pursuant to
an exemption or under strict controls. If our future products are not exempted
by the USDA, it may be impossible to sell such products.

IF THERE IS NEGATIVE PUBLIC REACTION TO THE USE OF GENETICALLY ENGINEERED
PRODUCTS AND TECHNOLOGIES, THEN THE MARKET FOR OUR PRODUCTS AND TECHNOLOGIES
WILL BE ADVERSELY AFFECTED

The commercial success of some our products, if any, and of the products of some
of our collaborators, will depend in part on public acceptance of the use of
genetically engineered products including drugs, plants and plant products.
Claims that genetically engineered products are unsafe for consumption or pose a
danger to the environment may influence public attitudes. Negative public
reaction to genetically modified organisms and products could result in greater
government regulation of genetic research and resultant products, including
stricter labeling requirements, and could cause a decrease in the demand for our
products. The subject of genetically engineered organisms has received negative
publicity and aroused public debate in a number of countries, including the
United States and the countries of the European Community. The expressed
preferences of a significant portion of consumers, particularly in Europe, but
also in the United States, for non-genetically engineered food can substantially
limit the marketing of genetically engineered food crops. Ethical and other
concerns about our technologies, particularly the use of genes for commercial
purposes and the products resulting from this use, could lead to greater
regulation and trade restrictions on imports of genetically engineered products
and adversely affect the market acceptance of our products and technologies.
Governmental authorities could, for political or other reasons, limit the use of
genetic processes or prohibit the practice of our GENEWARE technology.
Consequently, if this regulation results in non-acceptance of food products
derived from genetically engineered food crops it could reduce or eliminate our
expected financial return from the Dow agreement in agricultural gene discovery
and function, and our ability to successfully collaborate with additional
companies in the agricultural industry.

WE MAY BE SUED FOR PRODUCT LIABILITY AND OUR PRODUCT LIABILITY INSURANCE MAY NOT
BE ADEQUATE

The testing, marketing and sale of each of our and our collaborators' products
will entail a risk of allegations of product liability, and third parties may
assert substantial product liability claims against us. While we have limited
product liability insurance to protect against product liability risks, adequate
insurance coverage may not be available at an acceptable cost, if at all, in the
future and a product liability claim or product recall could materially and
adversely affect our business. Inability to obtain sufficient insurance coverage
at an acceptable cost or otherwise to protect against potential product
liability claims could prevent or inhibit the commercialization of the products
we or our collaborators develop. If we are sued for any



                                       22
<PAGE>   25

injury allegedly caused by our products or our collaborators' products cause,
our liability could exceed our total assets and our ability to pay the
liability.

IF WE USE HAZARDOUS MATERIALS IN OUR BUSINESS IN A MANNER THAT CAUSES INJURY OR
VIOLATES LAWS, WE MAY BE LIABLE FOR SUBSTANTIAL DAMAGES

Our research and development processes involve the use of hazardous materials,
including chemicals and radioactive and biological materials. Our operations
also produce hazardous waste products. The chemicals we use include, but are not
limited to, flammable solvents such as methanol and ethanol, ethidium dye which
is a commonly used fluorescent dye for visualizing DNA and buffer solutions used
in the purification of DNA. We also use several radioisotopes including
phosphorous-32, carbon-14, sulfur-35, phosphorous-33, iodine-125 and hydrogen-3.
We cannot eliminate the risk of accidental contamination or discharge and any
resultant injury from these materials. Federal, state and local laws and
regulations govern the use, manufacture, storage, handling and disposal of these
materials. We could be subject to civil damages and criminal penalties in the
event of an improper or unauthorized release of, or exposure of individuals to,
hazardous materials. Further, it is possible that the materials we use could
contaminate another party's property. In addition, claimants may sue us for
injury or contamination that results from our use or the use by third parties of
these materials, and our liability may exceed our total assets and our ability
to pay the liability. In addition, compliance with environmental laws and
regulations is expensive, and current or future environmental regulations may
impair our research and development and production efforts. Although we have
general liability insurance, these policies contain exclusions for insurance
against claims arising from pollution from chemical or radioactive materials.
Our collaborators are working with these types of hazardous materials in
connection with our collaborations. In the event of a lawsuit or investigation,
we could be held responsible for any injury we or our collaborators cause to
persons or property by exposure to, or release of, any hazardous materials.

HEALTHCARE REFORM AND RESTRICTIONS ON REIMBURSEMENTS MAY LIMIT OUR FINANCIAL
RETURNS ON OUR PRODUCTS

Our ability and that of our collaborators to commercialize therapeutics and
diagnostic products may depend in part on the extent to which government health
administration authorities, private health insurers and other organizations will
reimburse us for the cost of these products. These third parties are
increasingly challenging both the need for and the price of new medical products
and services. Significant uncertainty exists as to the reimbursement status of
newly approved therapeutics and diagnostics, and adequate third party
reimbursement may not be available for any product to enable us to maintain
price levels sufficient to realize an appropriate return on our investment in
research and product development.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

PATENT PROTECTION IN THE BIOTECHNOLOGY INDUSTRY IS UNCERTAIN WHICH MAY RESULT IN
A DECREASE IN THE VALUE OF OUR PRODUCTS AND TECHNOLOGIES

We are involved in overlapping and rapidly evolving areas of biotechnology,
pharmaceutical development and basic research involving viral vectors, plant
transgenics, proteomics,



                                       23
<PAGE>   26

functional genomics and immunotherapy. Each of these areas has been the subject
of intense research and patenting activity throughout the world by our
commercial competitors, actual and potential collaborators, academic
institutions and government researchers. The U.S. Patent and Trademark Office
generally keeps patent applications secret until it issues a patent. We cannot
determine whether or not there are patents currently pending which, if issued,
would prevent us from practicing our core technologies, commercializing them or
developing commercially viable products based upon them.

The patent positions of biotechnology firms generally are highly uncertain and
involve complex legal and factual questions that will determine who has the
right to develop a particular product. No clear policy has emerged regarding the
breadth of claims covered in biotechnology patents in general and those relating
to gene sequences in particular. In addition, recently there has been public
debate questioning whether genomic sequence data should be patentable. The
biotechnology patent situation outside the United States is even more uncertain
and is currently undergoing review and revision in many countries. Changes in,
or different interpretations of, patent laws in the United States and other
countries might allow others to use our discoveries or to develop and
commercialize products and technologies similar to our products and technologies
without any compensation to us. Our potential collaborators or customers may
conclude that uncertainties about patent protection decrease the value of our
databases, products and services.

Throughout the world there are numerous issued patents, as well as published
European patent applications which may issue as patents, many of which relate to
our current operations, our anticipated future operations and the products we
are likely to develop. The scope of these patents is a matter of legal
interpretation and is subject to uncertainty. We have not obtained, nor do we
intend to obtain, opinions from our patent counsel that we have freedom to
conduct our commercial activities free of claims of patent infringement from
third parties. For example, we are aware of one company, Enzon, Inc., that has a
broad portfolio of patents which generically claim single chain antibodies and
that, in letters mailed to numerous companies including us, has asserted that
any company using or making such antibodies will require a patent license from
them. We are assessing these patents and have been informed that licenses are
available, but if these licenses are required, we may not be able to obtain them
on commercially reasonable terms.

OUR PATENT APPLICATIONS MAY NOT RESULT IN ISSUED PATENTS THAT ARE ENFORCEABLE

Our disclosures in our patent applications may not be sufficient to meet the
statutory requirements for patentability in all cases. As a result, we do not
know which of our patent applications will result in enforceable patents. Our
patent applications may not issue as patents, and any patents that are issued to
us may not provide commercially meaningful protection against competitors. Any
issued patent may not provide us with competitive advantages. Others may
challenge our patents or independently develop similar products which could
result in an interference proceeding in the U.S. Patent and Trademark Office.
Others may be able to design around our issued patents or develop products
similar to our products. In addition, others may discover uses for genes or
proteins other than those uses covered in our patents, and these other uses may
be separately patentable.



                                       24
<PAGE>   27

PUBLIC DISCLOSURE AND PATENTS RELATING TO GENES AND GENE SEQUENCES HELD BY
OTHERS MAY LIMIT OUR PROPRIETARY RIGHTS

The Human Genome Project and many companies and institutions have identified
genes and deposited those sequences in public databases and are continuing to do
so. These public disclosures might limit the scope of our claims or make
unpatentable subsequent patent applications on full-length gene sequences. We
are aware of issued patents and patent applications containing subject matter
such that we or our licensees or collaborators may require a license or rights
in order to research, develop or commercialize some of our products and
technologies. We may find that licenses relating to such subject matter will not
be available on acceptable terms, or at all.

PATENT INFRINGEMENT OR ENFORCEMENT LITIGATION OR INTERFERENCE PROCEEDINGS COULD
BE COSTLY AND DISRUPT OUR BUSINESS AND MAY PREVENT US FROM COMMERCIALIZING OUR
PRODUCTS

The technology that we use to develop our products and key resources, and those
that we incorporate in our products and technologies, may be subject to claims
by third parties, including our collaborators, that they infringe the patents or
proprietary rights of others. We also may need to enforce our patent rights in
actions against others, which could be expensive. The risk of this occurring
will tend to increase as the proteomics, genomics and biotechnology industries
expand, more patents are issued and other companies attempt to discover genes
and proteins and engage in other proteomics, genomics and biotechnology-related
businesses.

With respect to identifying proteins uniquely associated with disease states or
as targets for drug therapy, we are aware that companies have published patent
applications relating to nucleic acids encoding specific proteins. If the U.S.
Patent and Trademark Office issues patents to these companies, their patents may
limit our ability and the ability of our collaborators to practice under any
patents that may be issued to us. Also, even if the U.S. Patent and Trademark
office issues us a patent, the scope of coverage or protection afforded to the
patent may be limited.

WE MAY NOT BE ABLE TO PROTECT OUR KNOW-HOW AND TRADE SECRETS

We generally control the disclosure and use of our know-how and trade secrets
using confidentiality agreements. It is possible, however, that:

-   Some or all confidentiality agreements will not be honored

-   Third parties will independently develop equivalent technology

-   Disputes will arise with our consultants, collaborators or others concerning
    the ownership of intellectual property

-   Unauthorized disclosure of our know-how or trade secrets will occur

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Interest rate risk

Our exposure to market rate risk for changes in interest rates relates
primarily to our investment portfolio and debt obligations. Our exposures to
interest rate and other market risks at September 30, 2000 did not differ
significantly from those described below.

Investment portfolio

Our investments portfolio consists of cash, cash equivalents and marketable
securities. Cash equivalents are highly liquid investments with maturities at
the date of purchase of three months or less and are stated at cost. We maintain
cash equivalents generally in money market accounts or with maturity dates of
less than 90 days. We do not believe our exposure to interest rate risk is
material for these balances, which totaled $57.7 million at September 30, 2000.
We classify our marketable securities as held-to-maturity and, consequently, we
record them on the consolidated balance sheet at historical cost. Marketable
securities totaled $34.1 million at September 30, 2000 and consisted of
commercial paper.

We do not use derivative financial instruments in our investment portfolio, and
we place our investments with high-quality issuers and, by policy, limit the
amount of credit exposure to any one issuer.

If market interest rates were to change immediately and uniformly by 10% from
levels at September 30, 2000, the fair value of our cash equivalents and
marketable securities would change by an insignificant amount.

Debt obligations

Our debt obligations consist of notes payable maturing from 2000 to 2008. We
index substantially all of our debt to the commercial bank prime interest rate,
9.5% at September 30, 2000. If market interest rates were to change immediately
and uniformly by 10% from levels at September 30, 2000, our interest expense
would change by a similar percentage.

Foreign currency

We have operated primarily in the United States, and all revenues to date
reflect amounts payable in U.S. dollars. We have not had any material exposure
to foreign currency rate fluctuations relating to revenues or expenses.

           c)  During the quarter ended September 30, 2000, we granted options
               to purchase 218,200 shares of our common stock to directors,
               officers, employees and consultants under the Company's 2000
               Stock Plan. During the quarter ended September 30, 2000, option
               holders exercised options for 534,000 shares of our common stock
               which were not registered under the Securities Act of 1933, as
               amended.

               The issuance and sale of the above securities that were not
               registered under the Securities Act were deemed to be exempt from
               registration under the Securities Act in reliance upon Section
               4(2) Regulation D, or Rule 701 promulgated thereunder.

               333-34198) for its Initial Public Offering ("IPO") became
               effective on August 9, 2000, covering an aggregate of 5,750,000
               shares of its common stock, including the underwriters'
               overallotment option. The managing underwriters were J.P. Morgan

               On August 15, 2000, we closed on the sale of 5,000,000 shares of
               our common stock at an initial public offering price of $17.00
               per share, resulting in gross proceeds of $85.0 million. After
               deducting $5.9 million in underwriting discounts and $2.2 million
               of other related expenses, the net proceeds to the Company were
               approximately $76.9 million. On September 8, 2000, we sold an
               additional 750,000 shares of our common stock at the initial
               public offering price of $17.00 per share pursuant to the
               exercise by the underwriters of their overallotment option,
               resulting in gross proceeds of $12.8 million. After deducting
               $0.9 million of underwriters discounts, our net proceeds from the
               exercise of the overallotment were $11.9 million.

               We have invested the proceeds from our IPO in money market funds,
               corporate paper and short-term bonds. We intend to use the
               proceeds for research and development, product development,
               capital expenditures and working capital. A portion may also be
               used to acquire or invest in complementary businesses or to
               obtain rights to use complementary technologies.

               As a result of our IPO, all of the 5.6 million outstanding shares
               of Convertible Preferred Stock with a recorded value of $40.5
               million were automatically converted into 8.4 million shares of
               our common stock.
