1.   NATURE OF BUSINESS

The Medicines Company (the Company) was incorporated in Delaware on July 31,
1996. The Company is a pharmaceutical company engaged in the acquisition,
development and commercialization of late-stage development drugs or drugs
approved for marketing. The U.S. Food and Drug Administration approved
Angiomax(R) (bivalirudin) for use as an anticoagulant in patients with unstable
angina undergoing percutaneous transluminal coronary angioplasty in December
2000 and the Company commenced sales of Angiomax in the first quarter of 2001.
The Company was considered to be a development-stage enterprise, as defined in
Statement of Financial Accounting Standards No. 7, "Accounting and Reporting by
Development Stage Enterprises" through December 31, 2000. With the commencement
of sales in 2001, the Company is no longer considered to be a development-stage
enterprise.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared
in accordance with accounting principles generally accepted in the United States
for interim financial information and with the instructions to Form 10-Q.
Accordingly, they do not include all the information and footnotes required by
accounting principles generally accepted in the United States for complete
financial statements. In the opinion of management, the accompanying financial
statements include all adjustments, consisting only of normal recurring
accruals, considered necessary for a fair presentation of the Company's
financial position, results of operations, and cash flows for the periods
presented.

The results of operations for the three-month period ended March 31, 2002 are
not necessarily indicative of the results that may be expected for the entire
fiscal year ending December 31, 2002. These condensed consolidated financial
statements should be read in conjunction with the audited financial statements
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2001, filed with the Securities and Exchange Commission.

Cash, Cash Equivalents and Available for Sale Securities

The Company considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents. Cash equivalents at
March 31, 2002 and December 31, 2001 consist of investments in money market
funds. These investments are carried at cost, which approximates fair value. The
Company considers securities with original maturities of greater than three
months to be available-for-sale securities. Securities under this classification
are recorded at fair market value and unrealized gains and losses are recorded
as a separate component of stockholders' equity. The estimated fair value of the
available for sale securities is determined based on quoted market prices or
rates for similar instruments.

        NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                   (unaudited)

At March 31, 2002 and December 31, 2001, the Company held a certificate of
deposit for $125,000 with a one-year term that was pledged as a security deposit
on its facility lease in Parsippany, New Jersey.

Revenue Recognition

The Company recognizes revenue from product sales in accordance with generally
accepted accounting principles in the United States, including the guidance in
Staff Accounting Bulletin 101. Revenue is recognized when there is persuasive
evidence of an arrangement, delivery has occurred, the price is fixed and
determinable, and collectibility is reasonably assured.

The Company's products are sold with limited rights of return. In accordance
with Statement of Financial Accounting Standards No. 48 (SFAS 48) "Revenue
Recognition When Right of Return Exists", revenue is recognized when the price
to the buyer is fixed, the buyer is obligated to pay the Company and the
obligation to pay is not contingent on resale of the product, the buyer has
economic substance apart from the Company, the Company has no obligations to
bring about sale of the product and the amount of returns can be reasonably
estimated. Returns during the three months ended March 31, 2002 and 2001 were
not material.

The Company does not offer price protection to its customers. The Company's
products are primarily sold to wholesalers and distributors, who, in turn, sell
to hospitals. Hospitals that have signed contracts with the Company or that
participate in group purchasing organizations that have contracts with the
Company receive rebates based on their volume of purchases. The Company provides
for such estimated rebates at the time of sale and revenues are reported net of
such amounts.

Revenue under the arrangement with Nycomed Danmark A/S is recognized based on
the performance requirements of the agreement. The nonrefundable up-front
payment of $1.5 million is recorded as deferred revenue and is being recognized
ratably over the term of the agreement, currently estimated to be twelve years.
Revenue from future milestone payments will be recognized ratably over the
remaining term of the agreement. Product sales under this agreement will be
recognized in accordance with our established revenue recognition policy.

3.   NET LOSS PER SHARE

The following table sets forth the computation of basic and diluted net loss per
share for the three months ended March 31, 2002 and 2001.

Options to purchase 4,548,677 and 3,287,175 shares of common stock outstanding
as of March 31, 2002 and 2001, respectively, have not been included in the
computation of diluted net loss per share, as their effect would have been
antidilutive. Outstanding warrants to purchase 2,873,688 and 3,269,564 shares of
common stock as of March 31, 2002 and 2001, respectively, were also excluded
from the computation of diluted net loss per share as their effect would have
been antidilutive.

During the period January 1, 2000 to September 30, 2000, the Company issued
2,273,624 options at exercise prices below the estimated fair value of the
Company's common stock as of the date of grant of such options based on the
price of the Company's common stock in connection with the Company's initial
public offering. The total deferred stock compensation associated with these
options is approximately $17.3 million. The Company amortizes deferred stock
compensation over the respective vesting periods of the individual stock
options. Included in the results of operations for the three months ended March
31, 2002 and 2001 is compensation expense of approximately $985,000 and $1.1
million, respectively, associated with such options.

4.   COMPREHENSIVE LOSS

Comprehensive losses are primarily comprised of net losses, unrealized losses on
available for sales securities and currency translation adjustments.
Comprehensive losses for the three months ended March 31, 2002 and 2001 were
$11.6 million and $19.5 million, respectively.

5.   STUDY AND EXCLUSIVE OPTION AGREEMENT WITH ASTRAZENECA AB

On March 6, 2002, the Company entered into study and exclusive option agreement
with AstraZeneca AB for the licensing, development and commercialization of
clevidipine, an intravenous, short-acting calcium channel blocker. Clevidipine
will be developed in Phase 3 by the Company for the short-term control of high
blood pressure in the hospital setting.

        NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                   (unaudited)

AstraZeneca has completed clinical pharmacology, dose-finding and efficacy
studies that demonstrate that clevidipine has a short duration of action, a
short plasma half-life, and a selective effect on blood pressure. The Company
will perform further clinical development and has the right to commercialize the
product worldwide, except in Japan.

6.   SALES, MARKETING AND DISTRIBUTION AGREEMENT WITH NYCOMED DANMARK A/S

On March 25, 2002, the Company entered into a collaboration with Nycomed Danmark
A/S, a European pharmaceutical company, under which Nycomed will serve as the
exclusive distributor of Angiomax in 35 countries, including 12 countries in the
European Union. Nycomed will exclusively market and distribute Angiomax within
the territory. Nycomed paid an initial fee of $1.5 million and agreed to pay up
to $2.5 million in additional milestones based on regulatory approval in Europe.
In addition, Nycomed purchased 79,428 shares of the Company's common stock for a
total purchase price of approximately $1.0 million. The Company and Nycomed will
work together to achieve regulatory approval in the countries covered by the
agreement and share costs of clinical trials used to extend indications in
Europe beyond coronary angioplasty.

7.   LOAN AND SECURITY AGREEMENT WITH COMERICA BANK

On March 26, 2002, the Company signed a Loan and Security Agreement with
Comerica Bank-California providing for borrowings of up to $10.0 million.
Amounts outstanding under the agreement are collateralized by all of the
Company's personal property. In order to draw on the facility, and while
borrowings are outstanding, the Company must satisfy certain covenants,
including covenants related to cash, working capital and revenues. The
borrowings will be used to support working capital needs. At March 31, 2002, the
Company had drawn down the full $10.0 million under the agreement. Subsequent to
the end of the first quarter, the Company repaid in full the borrowings under
the facility.

8.   RECENT ACCOUNTING PRONOUNCEMENTS

In June 2001, the FASB issued SFAS No. 141, "Business Combinations", and SFAS
No. 142, "Goodwill and Other Intangible Assets." SFAS No. 141 supersedes APB No.
16, Business Combinations, and SFAS No. 38, "Accounting for Preacquisition
Contingencies of Purchased Enterprises", and requires that all business
combinations be accounted for by a single method - the purchase method. SFAS No.
141 also provides guidance on the recognition of intangible assets identified in
a business combination and requires enhanced financial statement disclosures.
SFAS No. 142 adopts a more aggregate view of goodwill and bases the accounting
for goodwill on the units of the combined entity into which an acquired entity
is integrated. In addition, SFAS No. 142 concludes that goodwill and intangible
assets that have indefinite useful lives will not be amortized but rather will
be tested at least annually for impairment. Intangible assets that have finite
lives will continue to be amortized over their useful lives. SFAS No. 141 is
effective

                                     Page 7



        NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                   (unaudited)

for all business combinations initiated after June 30, 2001. The adoption of
SFAS No. 142 is required for fiscal years beginning after December 15, 2001,
except for the nonamortization and amortization provision, which are required
for goodwill and intangible assets acquired after June 30, 2001. The Company
adopted this new standard and it did not have a material impact on the Company's
financial condition or results of operations.

In August 2001, the FASB issued SFAS No.143, "Accounting for Asset Retirement
Obligations". The standard requires entities to record the fair value of a
liability for an asset retirement obligation in the period in which it is
incurred. When the liability is initially recorded, the entity capitalizes a
cost by increasing the carrying amount of the related long-lived asset. Over
time, the liability is accreted to its present value each period, and the
capitalized cost is depreciated over the useful life of the related asset. Upon
settlement of the liability, an entity either settles the obligation for its
recorded amount or incurs a gain or loss upon settlement. The standard is
effective for fiscal years beginning after June 15, 2002, with earlier
application encouraged. The Company adopted this new standard and it did not
have a material impact on the Company's financial condition or results of
operations.

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-lived Assets." SFAS No. 144 supersedes SFAS No. 121,
"Accounting for the Impairment of Long-lived Assets and for Long-lived Assets to
be Disposed of", and certain provisions of Accounting Principles Board (APB)
Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of
Disposal of a Segment of a Business, Extraordinary, Unusual and Infrequent
Occurring Events and Transactions." SFAS No. 144 requires that one accounting
model be used for long-lived assets to be disposed of by sale, whether
previously held and used or newly acquired, and it broadens the presentation of
discontinued operations to include more disposal transactions. The standard is
effective for financial statements issued for fiscal years beginning after
December 15, 2001, and interim periods within those fiscal years, with early
adoption permitted. The Company adopted this new standard and it did not have a
material impact on the Company's financial condition or results of operations.

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

Our management's discussion and analysis of financial condition and results of
operations contains forward-looking statements and is subject to important
factors that could cause our future results to differ materially from those
indicated. See "Factors that May Affect Future Results" beginning on page 15.

GENERAL

We operate as a pharmaceutical company selling and developing products for the
treatment of hospital patients. We acquire, develop and commercialize
biopharmaceutical products that are in late stages of development or have been
approved for marketing. We began selling Angiomax(R), our lead product, in U.S.
hospitals in January 2001 as an anticoagulant replacement for heparin. In
December 2000, we received marketing approval from U.S. Food and Drug
Administration for Angiomax for use as an anticoagulant in combination with
aspirin in patients with unstable angina undergoing coronary balloon
angioplasty. Coronary balloon angioplasty is a procedure used to restore normal
blood flow in an obstructed artery in the heart.

In March 2002, we entered into an agreement with AstraZeneca AB for the
licensing, development and commercialization of clevidipine, an intravenous,
short-acting calcium channel blocker, for which Phase 3 clinical trials are
planned. Prior to our acquisition of clevidipine, AstraZeneca conducted Phase 2
clinical trials of clevidipine. These clinical trials demonstrated that
clevidipine acts to reduce blood pressure almost immediately after intravenous
infusion. In the first quarter of 2002, we also entered into an agreement with
Nycomed Danmark A/S under which Nycomed will serve as the exclusive distributor
of Angiomax in 35 countries, including 12 countries in the European Union.
Finally, in March 2002, we received an approvable letter from the U.S. Food and
Drug Administration for a second-generation process for the manufacture of
Angiomax bulk drug material, known as the Chemilog process.

Since our inception, we have incurred significant losses, including a net loss
of $11.6 million for the three months ended March 31, 2002. Most of our
expenditures to date have been for research and development activities and
selling, general and administrative expenses. Research and development expenses
represent costs incurred for product acquisition, clinical trials, activities
relating to regulatory filings and manufacturing development efforts. We
generally outsource our clinical trials and manufacturing development activities
to independent organizations to maximize efficiency and minimize our internal
overhead. We expense our research and development costs as they are incurred.
Selling, general and administrative expenses consist primarily of salaries and
related expenses, general corporate activities and costs associated with product
sales and marketing activities. Interest expense consists of costs associated
with the use of our revolving line of credit.

We expect to continue to incur operating losses for the foreseeable future as a
result of research and development activities attributable to new and existing
products and costs associated with the sales and marketing of our products. We
will need to generate significant revenues to achieve and maintain
profitability.

                                     Page 9


During the year ended December 31, 2000, we recorded deferred stock compensation
on the grant of stock options of approximately $17.3 million, representing the
difference between the exercise price of such options and the fair market value
of our common stock at the date of grant of such options. The exercise prices of
these options were below the estimated fair market value of our common stock as
of the date of grant based on the estimated price of our common stock in our
initial public offering. No additional deferred stock compensation was recorded
during the three months ended March 21, 2002 or during the full year 2001
because all grants of stock options during these periods were issued at the fair
market value on the date of grant.

We amortize deferred stock compensation over the respective vesting periods of
the individual stock options. We recorded amortization expense for deferred
stock compensation of approximately $985,000 and $1.1 million for the three
months ended March 31, 2002 and 2001, respectively. We expect to record
amortization expense for the deferred stock compensation as follows:
approximately $2.3 million for the remainder of 2002, approximately $2.9 million
in 2003 and approximately $1.0 million in 2004.

We have not generated taxable income to date. At December 31, 2001, net
operating losses available to offset future taxable income for federal income
tax purposes were approximately $173 million. If not utilized, federal net
operating loss carryforwards will expire at various dates beginning in 2011 and
ending 2021. We have not recognized the potential tax benefit of our net
operating losses in our statements of operations. The future utilization of our
net operating loss carryforwards may be limited pursuant to regulations
promulgated under the Internal Revenue Code of 1986, as amended.

CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

The discussion and analysis of our financial condition and results of operations
is based on our consolidated financial statements, which have been prepared in
accordance with accounting principles generally accepted in the United States.
The preparation of these financial statements requires us to make estimates and
judgments that affect the reported assets and liabilities, revenues and
expenses, and other financial information. Actual results may differ
significantly from these estimates under different assumptions and conditions.

The SEC has indicated that critical accounting estimates and judgments are those
which are both important to the portrayal of the company's financial condition
and results and require management's most difficult, subjective or complex
judgments, often as a result of the need to make estimates about the effect of
matters that are inherently uncertain.

Our significant accounting policies are more fully described in the Notes To
Unaudited Consolidated Financial Statements section of this Quarterly Report on
Form 10-Q and in Note 2 of the Company's Annual Report on Form 10-K for the year
ended December 31, 2001. Not all of these significant accounting policies,
however, require management to make difficult, complex or subjective judgments
or estimates. We believe that our accounting policies relating to revenue
recognition and inventory, as described under the caption "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Critical Accounting Policies" in our Form 10-K as of December 31, 2001, fit the
definition of "critical accounting estimates and judgments."

                                    Page 10


In addition to the critical accounting estimates and judgments described in our
Form 10-K as of December 31, 2001, we make critical accounting estimates and
judgments related to revenue recognition under collaborative agreements. Revenue
under our collaborative arrangement with Nycomed is recognized based on the
terms of the agreement. The terms of the collaborative arrangement include
nonrefundable licensing fees and payments based on the achievement of certain
milestones and on product sales. Nonrefundable up-front license fees or
milestone payments are recorded as deferred revenue and are recognized ratably
over the term of the agreement, estimated to be twelve years.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2002 and 2001

Net Revenue. Net revenue increased 314% to $7.7 million for the three months
ended March 31, 2002, from $1.9 million for the three months ended March 31,
2001. Virtually all the revenue for the three-month periods ended March 31, 2002
and 2001 came from U.S. sales of Angiomax, which we commercially launched during
the first quarter of 2001. The increase in 2002 was due primarily to increased
volume of sales to an increasing number of hospital customers. In the first
quarter of 2002, we began to recognize revenue associated with the amortization
of the nonrefundable up-front payment under the Nycomed agreement.

Cost of Revenue. Cost of revenue for the three months ended March 31, 2002 was
$1.1 million, or 14% of revenue, compared to $332,000, or 18% of revenue, for
the three months ended March 31, 2001. Cost of revenue consists of expenses in
connection with the manufacture of the Angiomax sold, the logistical costs of
selling Angiomax and royalty expenses under our agreements with Biogen. The cost
of manufacturing as a percentage of revenue was at approximately 4% for the
three months ended March 31, 2002 and approximately 2% for the three months
ended March 31, 2001 because we sold Angiomax during the periods that was
manufactured prior to the date of FDA approval of Angiomax in December 2000. The
costs associated with the manufacture of Angiomax prior to the date of FDA
approval of Angiomax were expensed as research and development. In the second
quarter of 2002, we expect to begin to sell Angiomax manufactured after the date
of FDA approval. As a result, we expect our cost of manufacturing as a
percentage of product revenue will increase substantially.

Research and Development Expenses. Research and development expenses decreased
26% to $9.3 million for the three months ended March 31, 2002, from $12.6
million for the three months ended March 31, 2001. The decrease in research and
development expenses of $3.3 million was primarily due to lower clinical
development costs reflecting the completion of the HERO-2 trial program, our
Phase 3 trial in acute myocardial infarction, in 2001. Partly offsetting the
decrease in clinical development costs associated with HERO-2 were the higher
clinical development costs related to our trials in angioplasty called REPLACE-2
and the cost incurred in connection with our receipt of the final Chemilog
validation batch of $2.5 million in the three months ended March 31, 2002.

                                    Page 11


We have a number of clinical trial programs currently underway, or about to
commence, for expanding the applications of Angiomax in the treatment of
ischemic heart disease and for use as a procedural anticoagulant. The funding
for Angiomax, our main product, has represented and will continue to represent a
significant portion of research and development spending. For the three-month
periods ended March 31, 2002 and 2001, research and development expenses related
to Angiomax included the costs of clinical trials, development manufacturing
costs for the bulk drug product and the cost associated with preparation of U.S.
and worldwide marketing applications. We expect our current primary clinical
trial of Angiomax, REPLACE-2, to complete enrollment during the third quarter of
2002. We are currently working on a second generation manufacturing process for
Angiomax, called Chemilog, for which we have received an approvable letter from
the FDA, and will continue to incur research and development expenses until we
receive FDA approval of this process. The amount of future research and
development expenses associated with Angiomax are not reasonably certain as
these costs are dependent upon the regulatory process and the timing for
obtaining marketing approval for other applications of the product in the United
States and other countries. However, they are expected to be substantial.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 3% to $9.3 million for the three months ended
March 31, 2002, from $9.1 million for the three months ended March 31, 2001. The
increase in selling, general and administrative expenses of $273,000 was
primarily due to an increase in marketing and selling expenses and corporate
infrastructure costs relating to the sales and marketing of Angiomax, including
the costs of the additional sales personnel hired in late 2001.

Other Income and Expense. Interest income decreased 65% to $378,000 for the
three months ended March 31, 2002, from $1.1 million for the three months ended
March 31, 2001. The decrease in interest income of $691,000 was primarily due to
lower cash and available for sale securities balances attributable to operating
expenses and working capital requirements and to lower available interest rates
on securities. The primary source of interest income is from the investment of
the remaining proceeds of our initial public offering in August and September
2000 and from the investment of the proceeds from our sale of 4.0 million shares
of our common stock in a private placement in May 2001.

We had interest expense of $8,000 during the three months ended March 31, 2002
associated with the drawdown of our revolving line of credit at the end of March
2002. We had no interest expense for the three months ended March 31, 2001.

LIQUIDITY AND CAPITAL RESOURCES

Since our inception, we have financed our operations through the sale of common
and preferred stock, sales of convertible promissory notes and warrants,
interest income, draw downs of our revolving line of credit and revenues from
sales of Angiomax.

In August and September 2000, we received $101.4 million in net proceeds from
the sale of common stock in our initial public offering, and we received an
additional $41.8 million in net proceeds in May 2001 from the sale of 4.0
million shares of our common stock in a private placement. Prior to the initial
public offering, we had received net proceeds of $79.4 million


                                    Page 12


from the private placement of equity securities, primarily redeemable
convertible preferred stock, and $19.4 million from the issuance of convertible
notes and warrants.

In March 2002, we entered into a collaboration with Nycomed Danmark A/S. Under
the agreement, Nycomed paid us an initial non-refundable fee of $1.5 million and
agreed to pay up to $2.5 million in additional milestones based on regulatory
approval in Europe. In addition, Nycomed purchased 79,428 shares of our common
stock for a total purchase price of approximately $1.0 million.

In March 2002, we entered into a loan and security agreement with Comerica
Bank-California. Under the agreement, we may borrow up to $10.0 million. Amounts
outstanding under the agreement are collateralized by all of the Company's
personal property. The agreement has a term of one year and provides for
interest on amounts outstanding at a rate of one percent above the prime rate.
In order to draw on the facility, and while borrowings are outstanding, we must
satisfy certain covenants, including covenants related to cash, working capital
and revenues. At March 31, 2002, we had drawn down the full $10.0 million under
the agreement. Subsequent to the end of the quarter, we repaid in full the
borrowings under this revolving line of credit.

As of March 31, 2002, we had $55.6 million in cash, cash equivalents and
available for sale securities, as compared to $54.0 million as of December 31,
2001. The increase in cash, cash equivalents and available for sale securities
of $1.6 million was primarily attributable to funds received from the $10.0
million draw down of our revolving line of credit, the $2.5 million received
from Nycomed Danmark A/S, consisting of a non-refundable upfront license fee of
$1.5 million and $1.0 million in proceeds from the sale of shares of our common
stock to Nycomed, and from collections on sales of Angiomax. This increase was
partly offset by operating expenses and working capital requirements during the
three-month period ended March 31, 2002.

We used net cash of $9.7 million in operating activities during the three months
ended March 31, 2002. This consisted of a net loss of $11.6 million, combined
with increases in accounts receivable of $1.3 million and inventory of $2.9
million, which were partly offset by an increase in accounts payable and accrued
expenses of $3.8 million, an increase in deferred revenue of $1.5 million
associated with the Nycomed agreement and from non-cash amortization of deferred
stock compensation of $985,000 and depreciation of $132,000. The increase in
inventory of $2.9 million was primarily attributable to the scheduled receipt of
bulk Angiomax from our supplier, UCB Bioproducts, during the three months ended
March 31, 2002. We do not expect to receive any additional Angiomax bulk
material in the second or third quarters of 2002.

During the three months ended March 31, 2002, we used approximately $6,000 of
cash from net investing activities, which consisted principally of the purchase
of fixed assets. During the three months ended March 31, 2002, we received $11.3
million from financing activities primarily related to the draw down of our
revolving line of credit of $10.0 million, proceeds from the sale of shares of
our common stock to Nycomed of $1.0 million and from employees purchasing stock
under our stock plans.

We expect to devote substantial resources to our research and development
efforts and to our sales, marketing and manufacturing programs associated with
the commercialization of our


                                    Page 13


products. Our funding requirements will depend on numerous factors including:

     o    whether Angiomax is commercially successful;

     o    the progress, level and timing of our research and development
          activities;

     o    the cost and outcomes of regulatory reviews;

     o    the continuation or termination of third party manufacturing or sales
          and marketing arrangements;

     o    the cost and effectiveness of our sales and marketing programs;

     o    the status of competitive products;

     o    our ability to defend and enforce our intellectual property rights;
          and

     o    the establishment of additional strategic or licensing arrangements
          with other companies or acquisitions.

We believe, based on our current operating plan, plus anticipated revenues from
Angiomax and interest income, that our current cash, cash equivalents and
available for sale securities will be sufficient to fund our operations for
approximately 15 months. If our existing resources are insufficient to satisfy
our liquidity requirements due to slower than anticipated revenues from Angiomax
or otherwise, or if we acquire additional product candidates, we may need to
sell additional equity or debt securities or seek additional financing through
other arrangements. On April 23, 2002, we filed a Form S-3 Shelf Registration
Statement with the Securities and Exchange Commission which will permit us, from
time to time, to offer and sell up to 4.0 million shares of our common stock.

The sale of additional equity or debt securities may result in additional
dilution to our stockholders, and we cannot be certain that additional public or
private financing will be available in amounts or on terms acceptable to us, if
at all. If we are unable to obtain this additional financing, we may be required
to delay, reduce the scope of, or eliminate one or more of our planned research,
development and commercialization activities, which could harm our financial
condition and operating results. In addition, in order to obtain additional
financing, we may be required to relinquish rights to products, product
candidates or technologies that we would not otherwise relinquish.

CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

Our contractual obligations and commercial commitments include:

     o    operating leases for our facilities in Cambridge, Massachusetts and
          Parsippany, New Jersey, which expire in August 2003 and September
          2005, respectively. Future annual minimum payments under these
          operating leases are $498,000 for the remainder of 2002, and $502,000,
          $282,000 and $177,000 in 2003, 2004 and 2005, respectively.

     o    a purchase order that was placed in March 2002 to UCB Bioproducts for
          the purchase of approximately $5.3 million of Angiomax bulk drug
          product. We expect to take delivery under this purchase order in late
          2002 and 2003.

     o    a revolving line of credit with Comerica Bank under which we may
          borrow up to $10.0 million. This revolving line of credit will be
          available to us until March 25, 2003. As of March 31, 2002, we had
          drawn down the full $10.0 million under the agreement, however,
          subsequent to the end of the quarter, we repaid in full borrowings
          under this


                                    Page 14


          revolving line of credit. We must repay any borrowings under the
          facility no later than March 25, 2003.

RISKS RELATED TO OUR BUSINESS

WE HAVE A HISTORY OF NET LOSSES, AND WE EXPECT TO CONTINUE TO INCUR NET LOSSES
AND MAY NOT ACHIEVE OR MAINTAIN PROFITABILITY

We have incurred net losses since our inception, including net losses of
approximately $11.6 million for the three months ended March 31, 2002. As of
March 31, 2002, we had an accumulated deficit of approximately $263.1 million.
We expect to make substantial expenditures to further develop and commercialize
our products, including costs and expenses associated with clinical trials,
regulatory approval and commercialization of products. As a result, we are
unsure when we will become profitable, if at all, and if we do become
profitable, we may not remain profitable for any substantial period of time. If
we fail to achieve profitability within the time frame expected by investors or
securities analysts, the market price of our common stock may decline.

OUR BUSINESS IS VERY DEPENDENT ON THE COMMERCIAL SUCCESS OF ANGIOMAX

Other than Angiomax, our products are in clinical phases of development and,
even if approved by the FDA, are a number of years away from entering the
market. As a result, Angiomax will account for almost all of our revenues for
the foreseeable future. The commercial success of Angiomax will depend upon its
acceptance by physicians, patients and other key decision-makers as a safe,
therapeutic and cost-effective alternative to heparin and other products used in
current practice. If Angiomax is not commercially successful, we will have to
find additional sources of revenues or curtail or cease operations.

FAILURE TO RAISE ADDITIONAL FUNDS IN THE FUTURE MAY AFFECT THE DEVELOPMENT,
MANUFACTURE AND SALE OF OUR PRODUCTS

                                    Page 15


Our operations to date have generated substantial and increasing needs for cash.
Our negative cash flow from operations is expected to continue into the
foreseeable future. The clinical development and regulatory approval of Angiomax
for additional indications, the development and regulatory approval of our other
product candidates and the acquisition and development of additional product
candidates by us will require a commitment of substantial funds. Our future
capital requirements are dependent upon many factors and may be significantly
greater than we expect.

As of the date of this Quarterly Report, we believe, based on our current
operating plan, plus anticipated sales of Angiomax and interest income, that our
current cash, cash equivalents and available for sale securities will be
sufficient to fund our operations for approximately 15 months. If our existing
resources are insufficient to satisfy our liquidity requirements due to slower
than anticipated sales of Angiomax or otherwise, or if we acquire additional
product candidates, we may need to sell additional equity or debt securities or
seek additional financing through other arrangements. The sale of additional
equity or debt securities may result in additional dilution to our stockholders,
and we cannot be certain that additional public or private financing will be
available in amounts or on terms acceptable to us, if at all. If we are unable
to obtain this additional financing, we may be required to delay, reduce the
scope of, or eliminate one or more of our planned research, development and
commercialization activities, which could harm our financial condition and
operating results. In addition, in order to obtain additional financing, we may
be required to relinquish rights to products, product candidates or technologies
that we would not otherwise relinquish.

WE CANNOT EXPAND THE INDICATIONS FOR ANGIOMAX UNLESS WE RECEIVE FDA APPROVAL FOR
EACH ADDITIONAL INDICATION. FAILURE TO EXPAND THESE INDICATIONS WILL LIMIT THE
SIZE OF THE COMMERCIAL MARKET FOR ANGIOMAX

In December 2000, we received approval from the FDA for the use of Angiomax as
an anticoagulant in combination with aspirin in patients with unstable angina
undergoing coronary balloon angioplasty. One of our key objectives is to expand
the indications for which the FDA will approve Angiomax. In order to do this, we
will need to conduct additional clinical trials and obtain FDA approval for each
proposed indication. If we are unsuccessful in expanding the approved
indications for the use of Angiomax, the size of the commercial market for
Angiomax will be limited.

FAILURE TO OBTAIN REGULATORY APPROVAL IN FOREIGN JURISDICTIONS WILL PREVENT US
FROM MARKETING ANGIOMAX ABROAD

We intend to market our products in international markets, including Europe. In
order to market our products in the European Union and many other foreign
jurisdictions, we or our distribution agents must obtain separate regulatory
approvals. In February 1998, we submitted a Marketing Authorization Application
("MAA") to the European Agency for the Evaluations of Medicinal Products, or the
EMEA, for use of Angiomax in unstable angina patients undergoing angioplasty.
Following extended interaction with European regulatory authorities, the
Committee of Proprietary Medicinal Products of the EMEA voted in October 1999
not to recommend Angiomax for approval in angioplasty. The United Kingdom and
Ireland dissented from this decision. We have withdrawn our application to the
EMEA and, as of the date of this Quarterly Report, plan to resubmit an MAA with
the results of the REPLACE-2 program, if positive. We may not be able to obtain
approval from any or all of the jurisdictions in which we seek approval to
market Angiomax. Obtaining foreign approvals may require additional trials and
additional expense.

                                    Page 16


THE DEVELOPMENT AND COMMERCIALIZATION OF OUR PRODUCTS MAY BE TERMINATED OR
DELAYED, AND THE COSTS OF DEVELOPMENT AND COMMERCIALIZATION MAY INCREASE, IF
THIRD PARTIES WHO WE RELY ON TO MANUFACTURE AND SUPPORT THE DEVELOPMENT AND
COMMERCIALIZATION OF OUR PRODUCTS DO NOT FULFILL THEIR OBLIGATIONS

Our development and commercialization strategy entails entering into
arrangements with corporate and academic collaborators, contract research
organizations, distributors, third-party manufacturers, licensors, licensees and
others to conduct development work, manage our clinical trials, manufacture our
products and market and sell our products outside of the United States. Although
we manage these services, we do not have the expertise or the resources to
conduct such activities on our own and, as a result, are particularly dependent
on third parties in most areas.

We may not be able to maintain our existing arrangements with respect to the
commercialization of Angiomax or establish and maintain arrangements to develop
and commercialize clevidipine or any additional product candidates or products
on terms that are acceptable to us. Any current or future arrangements for the
development and commercialization of our products may not be successful. If we
are not able to establish or maintain agreements relating to Angiomax,
clevidipine or any additional products on terms which we deem favorable, our
financial condition would be materially adversely affected.

Third parties may not perform their obligations as expected. The amount and
timing of resources that third parties devote to developing, manufacturing and
commercializing our products may not be within our control. Furthermore, our
interests may differ from those of third parties that manufacture or
commercialize our products. Disagreements that may arise with these third
parties could delay or lead to the termination of the development or
commercialization of our product candidates, or result in litigation or
arbitration, which would be time consuming and expensive.

If any third party that manufactures or supports the development or
commercialization of our products breaches or terminates its agreement with us,
or fails to conduct its activities in a timely manner, such breach, termination
or failure could:

     o    delay or otherwise adversely impact the development or
          commercialization of Angiomax, clevidipine, our other product
          candidates or any additional product candidates that we may acquire or
          develop;

     o    require us to undertake unforeseen additional responsibilities or
          devote unforeseen additional resources to the development or
          commercialization of our products; or

     o    result in the termination of the development or commercialization of
          our products.

WE ARE DEPENDENT ON A SINGLE SUPPLIER FOR THE PRODUCTION OF ANGIOMAX BULK DRUG
SUBSTANCE AND A DIFFERENT SINGLE SUPPLIER TO CARRY OUT ALL FILL-FINISH
ACTIVITIES FOR ANGIOMAX

We have no experience in manufacturing, and we lack the facilities and personnel
to manufacture products in accordance with FDA regulations. As of the date of
this Quarterly Report, we obtain all of our Angiomax bulk drug substance from
one manufacturer, UCB Bioproducts S.A., and rely on another manufacturer, Ben
Venue Laboratories, Inc., to carry out all fill-finish activities for Angiomax,
which includes final formulation and transfer of the drug into vials where it is
then freeze-dried and sealed.

                                    Page 17


The FDA requires that all manufacturers of pharmaceuticals for sale in or from
the United States achieve and maintain compliance with the FDA's current Good
Manufacturing Practice, or cGMP, regulations and guidelines. There are a limited
number of manufacturers that operate under cGMP regulations capable of
manufacturing Angiomax. As of the date of this Quarterly Report, we do not have
alternative sources for production of Angiomax bulk drug substance or to carry
out fill-finish activities. In the event that either of our current
manufacturers is unable to carry out its respective manufacturing obligations to
our satisfaction, we may be unable to obtain alternative manufacturing, or
obtain such manufacturing on commercially reasonable terms or on a timely basis.
If we were required to transfer manufacturing processes to other third party
manufacturers, we would be required to satisfy various regulatory requirements,
which could cause us to experience significant delays in receiving an adequate
supply of Angiomax. Any delays in the manufacturing process may adversely impact
our ability to meet commercial demands for Angiomax on a timely basis and supply
product for clinical trials of Angiomax.

IF WE DO NOT SUCCEED IN DEVELOPING A SECOND-GENERATION PROCESS FOR THE
PRODUCTION OF BULK ANGIOMAX DRUG SUBSTANCE, OUR GROSS MARGINS MAY BE BELOW
INDUSTRY AVERAGES

As of the date of this Quarterly Report, we are developing with UCB Bioproducts
a second-generation process for the production of bulk Angiomax drug substance.
This process, for which we have received an approvable letter from the FDA,
involves changes to the early manufacturing steps of our current process in
order to improve our gross margins on the future sales of Angiomax. If
regulatory approval of the process is not obtained or is delayed, then our
ability to improve our gross margins on future sales of Angiomax may be limited.

CLINICAL TRIALS OF OUR PRODUCT CANDIDATES ARE EXPENSIVE AND TIME-CONSUMING, AND
THE RESULTS OF THESE TRIALS ARE UNCERTAIN

Before we can obtain regulatory approvals for the commercial sale of any product
that we wish to develop, we will be required to complete pre-clinical studies
and extensive clinical trials in humans to demonstrate the safety and efficacy
of such product. As of the date of this Quarterly Report, we are conducting
clinical trials of Angiomax for use in the treatment of ischemic heart disease
and for additional potential hospital applications as a procedural
anticoagulant. There are numerous factors that could delay our clinical trials
or prevent us from completing our trials successfully. We, or the FDA, may
suspend a clinical trial at any time on various grounds, including a finding
that patients are being exposed to unacceptable health risks.

The rate of completion of clinical trials depends in part upon the rate of
enrollment of patients. Patient enrollment is a function of many factors,
including the size of the patient population, the proximity of patients to
clinical sites, the eligibility criteria for the trial, the existence of
competing clinical trials and the availability of alternative or new treatments.
In particular, the patient population targeted by some of our clinical trials
may be small. Delays in future planned patient enrollment may result in
increased costs and program delays.

In addition, clinical trials, if completed, may not show any potential product
to be safe or effective. Results obtained in pre-clinical studies or early
clinical trials are not always indicative of results that will be obtained in
later clinical trials. Moreover, data obtained from pre-clinical studies and
clinical trials may be subject to varying interpretations. As a result, the FDA
or other applicable regulatory authorities may not approve a product in a timely
fashion, or at all. Even if


                                    Page 18


regulatory approval to market a product is granted, the regulatory approval may
impose limitations on the indicated use for which the drug may be marketed.

OUR FAILURE TO ACQUIRE AND DEVELOP ADDITIONAL PRODUCT CANDIDATES OR APPROVED
PRODUCTS WILL IMPAIR OUR ABILITY TO GROW

As part of our growth strategy, we intend to acquire and develop additional
pharmaceutical product candidates or approved products. The success of this
strategy depends upon our ability to identify, select and acquire pharmaceutical
products in late-stage development or that have been approved and that meet the
criteria we have established. Because we neither have, nor intend to establish,
internal scientific research capabilities, we are dependent upon pharmaceutical
and biotechnology companies and other researchers to sell or license product
candidates to us.

Any product candidate we acquire will require additional research and
development efforts prior to commercial sale, including extensive pre-clinical
and/or clinical testing and approval by the FDA and corresponding foreign
regulatory authorities. All of our product candidates are prone to the risks of
failure inherent in pharmaceutical product development, including the
possibility that the product candidate will not be safe, non-toxic and effective
or approved by regulatory authorities. In addition, we cannot assure you that
any approved products that we develop or acquire will be:

     o    manufactured or produced economically;

     o    successfully commercialized; or

     o    widely accepted in the marketplace.

In addition, proposing, negotiating and implementing an economically viable
acquisition is a lengthy and complex process. Other companies, including those
with substantially greater financial, marketing and sales resources, may compete
with us for the acquisition of product candidates and approved products. We may
not be able to acquire the rights to additional product candidates and approved
products on terms that we find acceptable, or at all.

IF WE BREACH ANY OF THE AGREEMENTS UNDER WHICH WE LICENSE COMMERCIALIZATION
RIGHTS TO PRODUCTS OR TECHNOLOGY FROM OTHERS, WE COULD LOSE LICENSE RIGHTS THAT
ARE IMPORTANT TO OUR BUSINESS

We license commercialization rights to products and technology that are
important to our business, and we expect to enter into additional licenses in
the future. For instance, we acquired our first four products through exclusive
licensing arrangements. Under these licenses we are subject to commercialization
and development, sublicensing, royalty, insurance and other obligations. If we
fail to comply with any of these requirements, or otherwise breach these license
agreements, the licensor may have the right to terminate the license in whole or
to terminate the exclusive nature of the license. In addition, upon the
termination of the license we may be required to license to the licensor the
intellectual property that we developed.

OUR ABILITY TO MANAGE OUR BUSINESS EFFECTIVELY COULD BE HAMPERED IF WE ARE
UNABLE TO ATTRACT AND RETAIN KEY PERSONNEL AND CONSULTANTS

The biopharmaceutical industry has experienced a high rate of turnover of
management personnel in recent years. We are highly dependent on our ability to
attract and retain qualified personnel for the acquisition, development and
commercialization activities we conduct or


                                    Page 19


sponsor. If we lose one or more of the members of our senior management,
including our executive chairman, Dr. Clive A. Meanwell, or our chief executive
officer, David M. Stack, or other key employees or consultants, our ability to
implement successfully our business strategy could be seriously harmed. Our
ability to replace these key employees may be difficult and may take an extended
period of time because of the limited number of individuals in the biotechnology
industry with the breadth of skills and experience required to develop and
commercialize products successfully. Competition to hire from this limited pool
is intense, and we may be unable to hire, train, retain or motivate such
additional personnel.

WE FACE SUBSTANTIAL COMPETITION, WHICH MAY RESULT IN OTHERS DISCOVERING,
DEVELOPING OR COMMERCIALIZING COMPETING PRODUCTS BEFORE OR MORE SUCCESSFULLY
THAN WE DO

The biopharmaceutical industry is highly competitive. Our success will depend on
our ability to acquire and develop products and apply technology and our ability
to establish and maintain a market for our products. Potential competitors in
the United States and other countries include major pharmaceutical and chemical
companies, specialized biotechnology firms, universities and other research
institutions. Many of our competitors have substantially greater research and
development capabilities and experience, and greater manufacturing, marketing
and financial resources, than we do. Accordingly, our competitors may develop or
license products or other novel technologies that are more effective, safer or
less costly than existing products or technologies or products or technologies
that are being developed by us or may obtain FDA approval for products more
rapidly than we are able. Technological development by others may render our
products or product candidates noncompetitive. We may not be successful in
establishing or maintaining technological competitiveness.

BECAUSE THE MARKET FOR THROMBIN INHIBITORS IS COMPETITIVE, OUR PRODUCT MAY NOT
OBTAIN WIDESPREAD USE

We have positioned Angiomax as a replacement for heparin, which is widely used
and inexpensive, for use in patients with ischemic heart disease. Because
heparin is inexpensive and has been widely used for many years, medical
decision-makers may be hesitant to adopt our alternative treatment. In addition,
due to the high incidence and severity of cardiovascular diseases, competition
in the market for thrombin inhibitors is intense and growing. There are a number
of thrombin inhibitors currently on the market, awaiting regulatory approval and
in development, including orally administered agents.

THE LIMITED RESOURCES OF THIRD-PARTY PAYERS MAY LIMIT THE USE OF OUR PRODUCTS

In general, anticoagulant drugs may be classified in three groups: drugs that
directly or indirectly target and inhibit thrombin, drugs that target and
inhibit platelets and drugs that break down fibrin. Because each group of
anticoagulants acts on different components of the clotting process, we believe
that there will be continued clinical work to determine the best combination of
drugs for clinical use. We expect Angiomax to be used with aspirin alone or in
conjunction with other therapies. Although we are not positioning Angiomax as a
direct competitor to platelet inhibitors or fibrinolytic drugs, platelet
inhibitors and fibrinolytic drugs may compete with Angiomax for the use of
hospital financial resources. Many U.S. hospitals receive a fixed reimbursement
amount per procedure for the angioplasties and other treatment therapies they
perform. Because this amount is not based on the actual expenses the hospital
incurs, U.S. hospitals may have to choose among Angiomax, platelet inhibitors
and fibrinolytic drugs.

FLUCTUATIONS IN OUR OPERATING RESULTS COULD AFFECT THE PRICE OF OUR COMMON STOCK

                                    Page 20


Our operating results may vary from period to period based on the amount and
timing of sales of Angiomax, the availability and timely delivery of a
sufficient supply of Angiomax, the timing and expenses of clinical trials,
announcements regarding clinical trial results and product introductions by our
competitors, the availability and timing of third-party reimbursement and the
timing of approval for our product candidates. If our operating results do not
match the expectations of securities analysts and investors as a result of these
and other factors, the trading price of our common stock will likely decrease.

WE MAY UNDERTAKE STRATEGIC ACQUISITIONS IN THE FUTURE AND ANY DIFFICULTIES FROM
INTEGRATING SUCH ACQUISITIONS COULD DAMAGE OUR ABILITY TO ATTAIN OR MAINTAIN
PROFITABILITY

We may acquire additional businesses and products that complement or augment our
existing business. Integrating any newly acquired businesses or product could be
expensive and time-consuming. We may not be able to integrate any acquired
business or product successfully or operate any acquired business profitably.
Moreover, we may need to raise additional funds through public or private debt
or equity financing to acquire any businesses, which may result in dilution for
stockholders and the incurrence of indebtedness.

OUR REVENUES ARE SUBSTANTIALLY DEPENDENT ON A LIMITED NUMBER OF WHOLESALERS TO
WHICH WE SELL ANGIOMAX, AND SUCH REVENUES MAY FLUCTUATE FROM QUARTER TO QUARTER
BASED ON THE BUYING PATTERNS OF THESE WHOLESALERS

We sell Angiomax primarily to a limited number of national medical and
pharmaceutical distributors and wholesalers with distribution centers located
throughout the United States. During the three months ended March 31, 2002,
revenues from the sale of Angiomax to four wholesalers totaled approximately 97%
of our net revenues. Our reliance on this small number of wholesalers could
cause our revenues to fluctuate from quarter to quarter based on the buying
patterns of these wholesalers. In addition, if any of these wholesalers fail to
pay us on a timely basis or at all, our financial position and results of
operations could be materially adversely affected.


RISKS RELATED TO OUR INDUSTRY

IF WE DO NOT OBTAIN FDA APPROVALS FOR OUR PRODUCTS OR COMPLY WITH GOVERNMENT
REGULATIONS, WE MAY NOT BE ABLE TO MARKET OUR PRODUCTS AND MAY BE SUBJECT TO
STRINGENT PENALTIES

Except for Angiomax, which has been approved for sale in the United States and
New Zealand, we do not have a product approved for sale in the United States or
any foreign market. We must obtain approval from the FDA in order to sell our
product candidates in the United States and from foreign regulatory authorities
in order to sell our product candidates in other countries. We must successfully
complete our clinical trials and demonstrate manufacturing capability before we
can file with the FDA for approval to sell our products. The FDA could require
us to repeat clinical trials as part of the regulatory review process. Delays in
obtaining or failure to obtain regulatory approvals may:

     o    delay or prevent the successful commercialization of any of our
          product candidates;

     o    diminish our competitive advantage; and

     o    defer or decrease our receipt of revenues or royalties.

The regulatory review and approval process is lengthy, expensive and uncertain.
Extensive pre-clinical data, clinical data and supporting information must be
submitted to the FDA for each


                                    Page 21

additional indication to obtain such approvals, and we cannot be certain when
we will receive these regulatory approvals, if ever.

In addition to initial regulatory approval, our products and product candidates
will be subject to extensive and rigorous ongoing domestic and foreign
government regulation. Any approvals, once obtained, may be withdrawn if
compliance with regulatory requirements is not maintained or safety problems are
identified. Failure to comply with these requirements may also subject us to
stringent penalties.

WE MAY NOT BE ABLE TO OBTAIN OR MAINTAIN PATENT PROTECTION FOR OUR PRODUCTS, AND
WE MAY INFRINGE THE PATENT RIGHTS OF OTHERS

The patent positions of pharmaceutical and biotechnology companies like us are
generally uncertain and involve complex legal, scientific and factual issues.
Our success depends significantly on our ability to:

     o    obtain U.S. and foreign patents;

     o    protect trade secrets;

     o    operate without infringing the proprietary rights of others; and

     o    prevent others from infringing our proprietary rights.

We may not have any patents issued from any patent applications that we own or
license. If patents are granted, the claims allowed may not be sufficiently
broad to protect our technology. In addition, issued patents that we own or
license may be challenged, invalidated or circumvented. Our patents also may not
afford us protection against competitors with similar technology. Because patent
applications in the United States and many foreign jurisdictions are typically
not published until eighteen months after filing and because publications of
discoveries in the scientific literature often lag behind actual discoveries, we
cannot be certain that others have not filed or maintained patent applications
for technology used by us or covered by our pending patent applications without
our being aware of these applications.

We exclusively license U.S. patents and patent applications and corresponding
foreign patents and patent applications relating to Angiomax, IS-159 and CTV-05.
The principal U.S. patent that covers Angiomax expires in 2010. The U.S. Patent
and Trademark Office has rejected our application for an extension of the term
of the patent beyond 2010 because the application was not filed in time. We
filed the application in connection with FDA approval of Angiomax. We are
exploring an alternative to extend the term of the patent, but we can provide no
assurance that we will be successful. We have not yet filed any independent
patent applications.

We may not hold proprietary rights to some patents related to our product
candidates. In some cases, others may own or control these patents. As a result,
we may be required to obtain licenses under third-party patents to market some
of our product candidates. If licenses are not available to us on acceptable
terms, we will not be able to market these products.

We may become a party to patent litigation or other proceedings regarding
intellectual property rights. The cost to us of any patent litigation or other
proceeding, even if resolved in our favor, could be substantial. If any patent
litigation or other intellectual property proceeding in which we are involved is
resolved unfavorably to us, we may be enjoined from manufacturing or selling our
products without a license from the other party, and we may be held liable for
significant damages. We may not be able to obtain any required license on
commercially acceptable terms, or at all.

                                    Page 22


IF WE ARE NOT ABLE TO KEEP OUR TRADE SECRETS CONFIDENTIAL, OUR TECHNOLOGY AND
INFORMATION MAY BE USED BY OTHERS TO COMPETE AGAINST US

We rely significantly upon unpatented proprietary technology, information,
processes and know-how. We seek to protect this information by confidentiality
agreements with our employees, consultants and other third-party contractors, as
well as through other security measures. We may not have adequate remedies for
any breach by a party to these confidentiality agreements. In addition, our
competitors may learn or independently develop our trade secrets.

WE COULD BE EXPOSED TO SIGNIFICANT LIABILITY CLAIMS IF WE ARE UNABLE TO OBTAIN
INSURANCE AT ACCEPTABLE COSTS AND ADEQUATE LEVELS OR OTHERWISE PROTECT OURSELVES
AGAINST POTENTIAL PRODUCT LIABILITY CLAIMS

Our business exposes us to potential product liability risks, which are inherent
in the testing, manufacturing, marketing and sale of human healthcare products.
Product liability claims might be made by patients in clinical trials,
consumers, health care providers or pharmaceutical companies or others that sell
our products. These claims may be made even with respect to those products that
are manufactured in licensed and regulated facilities or otherwise possess
regulatory approval for commercial sale.

These claims could expose us to significant liabilities that could prevent or
interfere with the development or commercialization of our products. Product
liability claims could require us to spend significant time and money in
litigation or pay significant damages. As of the date of this Quarterly Report,
we are covered, with respect to our commercial sales in the United States and
New Zealand and our clinical trials, by primary product liability insurance in
the amount of $20.0 million per occurrence and $20.0 million annually in the
aggregate on a claims-made basis. This coverage may not be adequate to cover any
product liability claims.

As we commercialize our products, we may wish to increase our product liability
insurance. Product liability coverage is expensive. In the future, we may not be
able to maintain or obtain such product liability insurance on reasonable terms,
at a reasonable cost or in sufficient amounts to protect us against losses due
to product liability claims.

OUR ABILITY TO GENERATE FUTURE REVENUE FROM PRODUCTS WILL DEPEND ON
REIMBURSEMENT AND DRUG PRICING

Acceptable levels of reimbursement of the cost of developing and manufacturing
of drugs and treatments related to those drugs by government authorities,
private health insurers and other organizations will have an effect on the
successful commercialization of, and attracting collaborative partners to invest
in the development of, our product candidates. We cannot be sure that
reimbursement in the United States or elsewhere will be available for any
products we may develop or, if already available, will not be decreased in the
future. If reimbursement is not available or is available only to limited
levels, we may not be able to commercialize our products, and may not be able to
obtain a satisfactory financial return on our products.

Third-party payers increasingly are challenging prices charged for medical
products and services. Also, the trend toward managed health care in the United
States and the changes in health insurance programs, as well as legislative
proposals to reform health care or reduce government insurance programs, may
result in lower prices for pharmaceutical products, including any products that
may be offered by us in the future. Cost-cutting measures that health care
providers are instituting, and the effect of any health care reform, could
materially adversely affect our ability to sell any products that are
successfully developed by us and approved by


                                    Page 23


regulators. Moreover, we are unable to predict what additional legislation or
regulation, if any, relating to the health care industry or third-party coverage
and reimbursement may be enacted in the future or what effect such legislation
or regulation would have on our business.


ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk is confined to our cash, cash equivalents and
marketable securities. We place our investments in high-quality financial
instruments, primarily money market funds and corporate debt securities with
maturities or auction dates of less than one year, which we believe are subject
to limited credit risk. We currently do not hedge interest rate exposure. At
March 31, 2002, we held $55.6 million in cash, cash equivalents, and available
for sale securities, all due within one year, which had an average interest rate
of approximately 2.0%. We do not believe that a 10% increase or decrease in
interest rates in effect at March 31, 2002 would have a material impact on our
results of operations or cash flows.

Most of our transactions are conducted in U.S. dollars. We do have certain
development and commercialization agreements with vendors located outside the
United States. Transactions under certain of these agreements are conducted in
U.S. dollars, subject to adjustment based on significant fluctuations in
currency exchange rates. Transactions under certain other of these agreements
are conducted in the local foreign currency. We do not believe that a 10%
increase or decrease in foreign currency exchange rates would have a material
impact on our results of operations or cash flows.

PART II.  OTHER INFORMATION

ITEM 2 - CHANGES IN SECURITIES AND USE OF PROCEEDS

          In our initial public offering, we sold 6.9 million shares of common
          stock (including an over-allotment option of 900,000 shares) pursuant
          to a Registration Statement on Form S-1 (File No. 333-37404) that was
          declared effective by the Securities and Exchange Commission on August
          7, 2000. We received aggregate net proceeds of approximately $101.4
          million, after deducting underwriting discounts and commissions of
          approximately $7.7 million and expenses of the offering of
          approximately $1.3 million. Of the aggregate net proceeds of
          approximately $101.4 million from the IPO, we used the entire amount
          during the period August 7, 2000 through March 31, 2002 for general
          corporate purposes, including operations, working capital and capital
          expenditures. Of the approximately $101.4 million, we paid
          approximately $711,000 to Stack Pharmaceuticals, Inc. and
          approximately $7.2 million to Innovex, Inc. Prior to becoming our
          President and Chief Executive Officer, David M. Stack was President
          and General Partner of Stack Pharmaceuticals and a Senior Advisor to
          the Chief Executive Officer of Innovex. Other than these payments,
          none of the net proceeds of the IPO has been paid by us, directly or
          indirectly, to any director, officer or general partner of us, or any
          of their associates, or to any person owning ten percent or more of
          any class of our equity securities, or any of our affiliates.
