      NOTE 1.  INTERIM FINANCIAL STATEMENTS

      The accompanying unaudited consolidated financial statements of Human
      Genome Sciences, Inc. (the "Company") have been prepared in accordance
      with accounting principles generally accepted in the United States for

      the consolidated financial statements reflect all adjustments necessary to
      present fairly the results of operations for the three and six month
      periods ended June 30, 2001 and 2000, the Company's financial position at
      June 30, 2001, and the cash flows for the six month periods ended June 30,
      2001 and 2000. These adjustments are of a normal recurring nature.

      The results of operations, cash flows and comprehensive income for the
      three and six month periods ended June 30, 2000 have been restated to
      reflect the implementation of SEC Staff Accounting Bulletin No. 101,
      "Revenue Recognition in Financial Statements" ("SAB 101") in 2000,
      retroactive to January 1, 2000. In addition, share and per share amounts
      have been restated to reflect a two-for-one stock split paid in the form
      of a stock dividend on October 5, 2000.

      Certain notes and other information have been condensed or omitted from
      the interim consolidated financial statements presented in this Quarterly
      Report on Form 10-Q. Therefore, these financial statements should be read
      in conjunction with the Company's 2000 Annual Report on Form 10-K and the
      Company's March 31, 2001 Quarterly Report on Form 10-Q.

      The results of operations for the three and six month period ended June
      30, 2001 are not necessarily indicative of future financial results.

      This pro forma information does not purport to be indicative of the
      results which may have been obtained had the acquisition been consummated
      at the date assumed.

      During the first quarter of 2001, the Company announced its decision to
      relocate Principia's operations from Norristown, Pennsylvania to the
      Company's Rockville, Maryland location. As a result, the Company recorded
      a one-time charge in the first quarter of 2001 of approximately $1,900,
      representing unit relocation costs and the write off of the remaining book
      value of Principia's Assembled Workforce.

      The balance of the unit relocation reserve was approximately $1,500 as of
      June 30, 2001. In addition, the Company expects to incur approximately
      $530 in personnel relocation costs and stay bonuses in the second half of
      2001.

      NOTE 4.  RECENT SEC INTERPRETATIONS

      During the fourth quarter of 2000, the Company implemented SAB 101. SAB
      101 provides guidance related to revenue recognition based on
      interpretations and practices followed by the SEC. SAB 101 requires
      revenues to be recognized ratably over the life of a contract period
      whereas, previously, the Company generally recognized revenue as
      non-refundable cash payments were made assuming no significant obligations
      remained. SAB 101 requires companies to report any changes in revenue
      recognition as a cumulative effect of a change in accounting principle at
      the time of implementation in accordance with Accounting Principles Board
      Opinion No. 20, "Accounting Changes".

      Historically, the Company has recognized non-refundable license fees,
      research payments, additional payments and milestone payments in
      connection with collaboration agreements when the revenue is earned in
      accordance with the applicable performance requirements and/or contractual
      terms. This revenue recognition policy was applicable to certain
      multi-year agreements the Company entered into with Schering-Plough,
      Sanofi-Synthelabo and Merck KgaA during 1996 (the "1996 Agreements"). The
      Company recognized revenue under these agreements when it had performed
      all significant obligations and the customer was obligated to pay. The
      Company generally considered any remaining performance obligation, such as
      maintaining access to its genomic databases, as insignificant. However,
      SAB 101 provides guidance that indicates revenue recognition over the
      collaboration term is generally the required treatment for all fees,
      regardless of the significance of remaining performance obligations.

      As a result of the implementation of SAB 101, the Company recorded a
      charge to earnings in 2000 in the form of a cumulative effect of a change
      in accounting principle and additional deferred revenue in the amount of
      $8,250. The Company has recognized this deferred amount as revenue during
      both the first and second quarters of 2001 in the amount of $4,125 per
      quarter.

Transgene, S.A.

      Revenues for the six months ended June 30, 2001 were $10.5 million
including the recognition of $3.8 million in revenue from Schering Corporation
and Schering Plough Ltd., $3.2 million in revenue recognized from Merck KGaA,
$2.2 million in revenue recognized from Synthelabo, and $1.3 million recognized
in revenue from Transgene, S.A. As a result of our implementation of SAB 101
last year, revenues for the six months ended June 30, 2000 have been restated.
Revenues for the six months ended June 30, 2000 were $10.5 including the
recognition of $3.8 million in revenue from Schering Corporation and Schering
Plough Ltd., $3.2 million in revenue recognized from Merck KGaA, $2.2 million in
revenue recognized from Synthelabo, and $1.3 million recognized in revenue from
Transgene, S.A.

      Related party revenues include revenues from Transgene in which we hold a
minority interest.

      We expect that our revenues may be limited to interest income, payments
under existing collaboration agreements which are contingent on meeting certain
product milestones, license fees, proceeds from the sale of rights and other
payments from other collaborators and licensees under existing or future
arrangements, to the extent that we enter into any such further arrangements.
Revenues from Schering, Synthelabo and Merck have substantially concluded for
fiscal year 2001. On June 30, 2001, the exclusivity period, or initial research
term, relating to our consortium with these collaborators concluded. While none
of the consortium members chose to renew the initial research term, work already
initiated by the members can continue if evidence of continued diligence is
provided. If any program results in drugs that are commercialized, we will be
entitled to certain milestone and royalty payments. In addition, for drugs
developed by GlaxoSmithKline, we will be entitled to certain co-promotion
rights. We can provide no assurance that any of these drugs can be successfully
commercialized.

     Expenses. Research and development expenses were $36.5 million for the
three months ended June 30, 2001 compared to $21.7 million for the three months
ended June 30, 2000. The increase is due primarily to increased operations costs
related to our leased manufacturing and process development facility as well as
increased expenditures in preclinical research and clinical trial research.
Research and development expenses were $68.6 million for the six months ended
June 30, 2001 compared to $41.2 million for the six months ended June 30, 2000.
The increase is due primarily to increased operations costs related to our
leased manufacturing and process development facility as well as increased
expenditures in preclinical research and clinical trial research. In addition,
research and development expenses for the six months ended June 30, 2001 include
$1.9 million in unit relocation costs and asset write-downs relating to the
relocation of Principia's operations to our Rockville, Maryland location as
discussed in Note 2 to the Consolidated Financial Statements.

     General and administrative expenses increased to $9.7 million for the three
months ended June 30, 2001 from $6.5 million for the three months ended June 30,
2000. General and administrative expenses increased to $18.0 million for the six
months ended June 30, 2001 from $12.5 million for the six months ended June 30,
2000. The increase for both the three and six month periods ended June 30, 2001
resulted primarily from



                                       10
   11
RESULTS OF OPERATIONS, CONTINUED

higher legal expenses associated with filing and prosecuting a larger number of
patent applications relating to genes and proteins we discovered, along with
increased business and product development expenses in support of our expanding
activities.

      Interest income increased for both the three and six month periods ended
June 30, 2001 compared to the three and six month periods ended June 30, 2000
due to higher cash balances arising primarily from our public offering of common
stock during the fourth quarter of 2000 that raised net proceeds of
approximately $912.7 million. Interest expense decreased for the three month
period due primarily to a reduction in the average debt balance for 2001
compared to 2000 as a result of the conversion to equity of $318.3 million of
convertible subordinated debt during the first quarter of 2000. Interest expense
increased for the six month period ended June 30, 2001 compared to the six month
period ended June 30, 2000 due primarily to an increase of $525.0 million in
convertible subordinated debt during the first quarter of fiscal 2000, partially
offset by the convertible subordinated note conversions discussed herein.

      Debt conversion expenses of $3.9 million for the three and six months
ended June 30, 2001 relate to the second quarter of 2001 conversion of $25.5
million aggregate principal amount of convertible subordinated notes into
equity. We converted $25.0 million of our outstanding $224.9 million aggregate
principal amount of 5% Notes Due 2007 into common stock at a cost of $3.9
million, substantially all of which was paid in the form of common stock. We
also converted $0.5 million of our 5 1/2% Notes Due 2006 into common stock. Debt
conversion expenses of $50.8 million for the six months ended June 30, 2000
relate to the first quarter of fiscal 2000 conversion costs of $318.3 million
aggregate principal amount of convertible subordinated notes into equity. We
converted $118.3 million of our 5 1/2% Notes Due 2006 into common stock at a
cost of $20.8 million, substantially all of which was paid in the form of common
stock. In addition, we converted all of our $200.0 million aggregate principal
amount of 5% Notes Due 2006 into common stock at a cost of $30.0 million, all of
which was paid in cash.

      Cumulative effect of a change in accounting principle of $8.3 million for
the six months ended June 30, 2000 relates to our implementation of Securities
and Exchange Commission ("SEC") Staff Accounting Bulletin No. 101, "Revenue
Recognition in Financial Statements" ("SAB 101"). As a result of the
implementation of SAB 101, we recorded a charge of $8.3 million as a cumulative
effect of a change in accounting principle, retroactive to January 1, 2000.

     Net Income. We recorded a net loss of $24.0 million, or $0.19 per share,
for the three months ended June 30, 2001 compared to a net loss of $16.4
million, or $0.15 per share, for the three months ended June 30, 2000. The
increased loss for the three month period of 2001 reflects the increase in
operations at our leased manufacturing and process development facility,
increased investment in the development of preclinical and clinical drug
candidates, increased general and administrative activities, as well as debt
conversion expenses, partially offset by the increase in net interest income.
Excluding the charge for debt conversion expenses incurred in 2001, our net loss
for the three months ended June 30, 2001 would have been $20.1 million, or
$0.16 per share, compared to $16.4 million, or $0.15 per share for the three
months ended June 30, 2000. We recorded a net loss of $37.0 million, or $0.29
per share, for the six months ended June 30, 2001 compared to a net loss of
$88.9 million, or $0.84 per share, for the six months ended June 30, 2000. The
decreased loss for the six month period reflects the reduction of debt
conversion expenses and the absence of the cumulative effect of a change in
accounting principle in 2001, the increase in net interest income in 2001,
partially offset by the increase in operations at our leased manufacturing and
process development facility, increased investment in the development of
preclinical and clinical drug candidates, and increased general and
administrative activities. Excluding the charges for debt conversion expenses
for both fiscal year 2001 and 2000 and the cumulative effect of a change in
accounting principle incurred in the six months ended June 30, 2000, our net
loss for the six months ended June 30, 2001 would have been $33.2 million, or
$0.26 per share, compared to $29.8 million, or $0.28 per share for the six
months ended June 30, 2000.

LIQUIDITY AND CAPITAL RESOURCES

         We had working capital of $1.7 billion at June 30, 2001 and December
31, 2000. No significant transactions have occurred in the six months ended June
30, 2001 that have affected our working capital. Our restricted investments
increased during the second quarter of 2001 primarily due to a transfer of $55
million of investments into a restricted account as part of a long-term facility
lease we entered into during the quarter.

         We expect to continue to incur substantial expenses relating to our
research and development efforts, which are expected to increase relative to
historical levels as we focus on preclinical and clinical trials required for
the development of therapeutic protein and antibody product candidates.

         We expect that our existing funds and interest income will be
sufficient to fund our operations for the foreseeable future. Our future capital
requirements and the adequacy of our available funds will depend on many
factors, including scientific progress in our research and development programs,
the magnitude of those programs, the success of the consortium members
developing and commercializing drugs from existing programs, our ability to
establish additional collaborative and licensing arrangements, the cost involved
in preparing, filing, prosecuting, maintaining and enforcing patent claims and
competing technological and market developments.

         Our funds may be invested in U.S. Treasury and government agency
obligations, high grade corporate debt securities and commercial paper. Such
investments reflect our policy regarding the investment of liquid assets, which
is to seek a reasonable rate of return consistent with an emphasis on safety,
liquidity and preservation of capital.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

        Certain statements contained in Management's Discussion and Analysis of
Financial Condition and Results of Operations are forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. The
forward-looking statements are based on our current intent, belief and
expectations. These statements are not guarantees of future performance and are
subject to certain risks and uncertainties that are difficult to predict. Actual
results may differ materially from these forward-looking statements because of
our unproven business model, dependence on new technologies, uncertainty and
timing of clinical trials, ability to develop and commercialize products,
dependence on collaborators for services and revenue, substantial indebtedness,
intense competition, uncertainty of patent and intellectual property protection,
dependence on key management, uncertainty of regulation of products, dependence
on key suppliers, the impact of future alliances or transactions and other risks
that may be described in our filings with the Securities and Exchange
Commission. Existing and prospective investors are cautioned not to place undue
reliance on these forward-looking statements, which speak only as of today's
date. We undertake no obligation to update or revise the information contained
in this announcement whether as a result of new information, future events or
circumstances or otherwise.

ITEM 3.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     We do not have operations subject to risks of foreign currency
fluctuations, nor do we use derivative financial instruments in our operations
or investment portfolio. Our investment portfolio can be comprised of low-risk
U.S. Treasury securities or corporate debt having a rating of at least A1\P1.
The short-term nature of these securities, which have an average term of
approximately one year, significantly decreases the risk of a material loss
caused by a market change. We believe that a hypothetical 100 basis point
adverse move (increase) in interest rates along the entire interest rate yield
curve would adversely affect the net fair value of our cash, cash equivalents
and short-term investments by approximately $25.2 million, or approximately
1.5% of the aggregate fair value of $1.68 billion, at June 30, 2001. For these
reasons, and because these securities are almost always held to maturity, we
believe we do not have significant exposure to market risks associated with
changes in interest rates related to our corporate debt securities held as of
June 30, 2001. We believe that any market change related to our U.S. securities
held as of June 30, 2001 is not material to our consolidated financial
statements. However, given the short-term nature of these securities, a general
decline in interest rates would adversely affect the interest income from our
portfolio as securities mature and are replaced with securities having a lower
interest rate.

    As of June 30, 2001, the carrying values of our equity investments in
Transgene, Cambridge Antibody Technology (CAT) and Ciphergen Biosystems were
approximately $4.7 million, $40.5 million and $1.4 million, respectively. Our
investments in Transgene and Ciphergen Biosystems are subject to equity market
risk. Our investment in CAT is denominated in pounds sterling and is subject to
both foreign currency risk as well as equity market risk.
