ITEM 5.  OTHER INFORMATION

         Amendments to the Agreements Related to Anaderm Research Corp.

         In 1996, the Company entered into a joint venture with Pfizer Inc.
("Pfizer") and New York University ("NYU") to form Anaderm Research Corp.
("Anaderm"), a company dedicated to the discovery and development of safe,
effective, pharmacologically active agents for certain cosmetic and
quality-of-life indications, such as skin pigmentation, hair loss and wrinkling.
On April 23, 1996, in connection with the formation of Anaderm, the Company,
Pfizer, and Anaderm, entered into a Collaborative Research Agreement (the "1996
Research Agreement") for the discovery and development of novel compounds to
treat the conditions to which Anaderm was dedicated. The Company also entered
into a Stockholders' Agreement (the "1996 Stockholders' Agreement") with Pfizer,
Anaderm, NYU and certain NYU faculty members (the "Faculty Members"). Under the
1996 Stockholders' Agreement, Anaderm issued common stock to Pfizer and the
Company and options to purchase common stock to NYU and the Faculty Members (who
have exercised their options fully). Pfizer holds 82%, the Company holds 14% and
NYU and the Faculty Members collectively hold 4% of Anaderm's common stock. In
exchange for its 14% of Anaderm's common stock, the Company provided formatting
for high throughput screens and conducted compound screening at its own expense
under the 1996 Research Agreement.

         On April 23, 1999, the Company entered into an Amended and Restated
Collaborative Research Agreement (the "1999 Research Agreement") with Pfizer and
Anaderm to expand the collaborative program begun by the 1996 Research Agreement
and an Amended and Restated Stockholders' Agreement (the "1999 Stockholders'
Agreement") with Pfizer, Anaderm, NYU and the Faculty Members. The 1999 Research
Agreement is for a term of three years. Pfizer may terminate the 1999 Research
Agreement, however, after the first or second year of the term in its sole
discretion after consultation with Anaderm and the Company to determine whether
satisfactory progress has been made in the research program during the previous
year. The 1999 Research Agreement provides for funding by Pfizer of up to $35
million in total payments to Anaderm to fund the Company's research and
development activities during the three-year term and up to $15 million in
phase-down funding following expiration of the three-year term or earlier
termination by Pfizer. In the expanded program, the Company will continue to
provide a full range of capabilities including assay biology, high throughput
screening, compound libraries, combinatorial, medicinal, and natural product
chemistry, as well as pharmaceutics, pharmacokinetics and molecular biology. The
Company anticipates a significant increase in its staffing of the program to
conduct its drug discovery efforts during the term of the 1999 Research
Agreement. Anaderm or Pfizer will pay royalties to the Company on the sales of
products resulting from the collaboration.

         A significant change to the 1996 Stockholders' Agreement by the 1999
Stockholders' Agreement is the addition of a right on the part of each of the
Company, NYU


                                       2
<PAGE>   3
and each of the Faculty Members, exercisable at any time prior to December 31,
1999, to require Anaderm or Pfizer to purchase all, but not less than all, of
the shares of common stock of Anaderm held by each such stockholder for a fixed
price based upon a formula as set forth in the 1999 Stockholders' Agreement. The
stockholders, including the Company, also continue to have the right,
exercisable at any time subsequent to April 23, 2000, to require Anaderm or
Pfizer to purchase all, but not less than all, of the shares of common stock of
Anaderm held by each such stockholder at the "Fair Value" (as such term is
defined in the 1999 Stockholders' Agreement) of such shares. In addition,
Anaderm or Pfizer has the right, exercisable at any time subsequent to April 23,
2002, to require the Company, NYU or any Faculty Member to sell to Anaderm all,
but not less than all, of the shares of common stock of Anaderm held by such
stockholder at the Fair Value of such shares. In the 1996 Stockholders'
Agreement, this call right was exercisable by Anaderm only with respect to the
shares owned by NYU and the Faculty Members. Copies of the 1999 Research
Agreement and 1999 Stockholders' Agreement are attached hereto as Exhibits 10.1
and 10.2 and are incorporated herein by reference.

         Development Agreement with Pfizer Inc.

         Effective as of April 1, 1999, the Company entered into a Development
Agreement (the "Agreement") with Pfizer for the development of certain compounds
derived from the Collaborative Research Agreement, dated as of April 1, 1996,
between Pfizer and the Company. Under the Agreement, the Company will conduct a
development program formulated by the Company and Pfizer which includes
pre-clinical and clinical research through and including Phase II clinical
trials for compounds to assess their safety and efficacy to be developed as
therapeutic agents for the treatment of psoriasis and other related dermal
pathologies. Pursuant to the terms of the Agreement, Pfizer has granted to the
Company an exclusive, with the exception of Pfizer, license to make and use the
compounds for all research purposes in the development program other than the
sale or manufacture for sale of products or processes. At the end of the
development program, Pfizer must notify the Company of its intention to continue
development and commercialization of a compound within three (3) months
following receipt of the data package from the clinical studies. If Pfizer does
so notify the Company of such intention, it will have an exclusive, world-wide
license, with the right to grant sublicenses, to make, use, sell, offer for sale
and import products developed in the course of the development program. If
Pfizer fails to notify the Company of such intention, the Company will receive
an exclusive, world-wide, royalty-bearing license, including the right to grant
sublicenses, to manufacture, use, sell, offer for sale and import products
developed in the course of the development program. The Company, however, has
the right to refuse to accept this license. The party receiving the license must
pay milestone and royalty payments as consideration therefor. The duration of
the licenses is coextensive with the lives of patents related to the licensed
compounds. Each of the parties has rights and obligations to prosecute and
maintain patent rights related to specified areas of the research under the
Agreement. The Agreement is subject to early termination in the event of certain
defaults by the parties. A copy of the Agreement is attached hereto as Exhibit
10.3 and is incorporated herein by reference.

         Amendment to the Collaborative Agreement with Novartis Pharma AG

         During the quarter ended June 30, 1999, the Company entered into
Amendment Nos. 1 and 2, dated April 13, 1999 and May 31, 1999, respectively, to
its Collaborative Agreement, dated April 19, 1995 (the "1995 Agreement") with
Novartis Pharma AG ("Novartis"). Pursuant to the 1995 Agreement, the Company
granted to Novartis an exclusive license with the right to grant sublicenses to
manufacture, have manufactured, use and sell products containing TGF-Beta 3 for
certain indications, referred to as Licensed Indications. The Company also
granted to Novartis an option (originally to expire in April 1999) to acquire
from the Company a license to manufacture, use and sell products containing
TGF-Beta 3 and other TGF-Betas for all other indications not included in the
Licensed Indications. The four year time limit to exercise the option was
extended until May 31, 1999 by Amendment No. 1 to the 1995 Agreement.

         Amendment No. 2 changed certain terms of the 1995 Agreement including
the definition of Licensed Indications, the supply of TGF-Betas, the amount of
royalty payments, and the schedules of the Company's patents and applications
and Novartis' patents. Specifically, oral mucositis and the healing of soft
wound tissue were removed from the Licensed Indications. Novartis acknowledged
in Amendment No. 2 that it has discontinued development of products for the
indications of oral mucositis and healing of soft wound tissue. The parties
agreed that all licenses theretofore granted to Novartis with respect to such
discontinued indications are terminated and that the Company is free to continue
development work and to grant licenses to third parties with respect to such
discontinued indications. The Company is also free to use the results of any
development work with respect to the discontinued indications carried out by
Novartis prior to the date of Amendment No. 2 provided that the Company pays to
Novartis royalties and/or certain other agreed-upon amounts with respect to
sales of products resulting from any such continued development work by the
Company or a licensee thereof. Under Amendment No. 2, the new Licensed
Indications are bone, cartilage and tendon repair. Novartis' option was changed
in Amendment No. 2 from an option to include in the definition of Licensed
Indications all indications not already included to (a) an exclusive option to
include in Licensed Indications the treatment of transplant patients (e.g.,
graft protection), the treatment of ischemia (e.g., angina pectoris and
peripheral vascular disease), the treatment of stroke patients, and the
treatment of inflammatory bowel disease, and (b) a non-exclusive option to
include any other additional indications relating to TGF-Betas (other than the
discontinued indications). The payment terms for the option were also amended
and the time period to exercise the option was extended until May 31, 2003.
Copies of Amendment Nos. 1 and 2 are attached hereto as Exhibits 10.4 and 10.5
and are incorporated herein by reference.

         Asset Purchase Agreement with Cadus Pharmaceutical Corporation

         (a)      Description of the Acquisition

         On July 30, 1999, the Company acquired certain assets from Cadus
Pharmaceutical Corporation, a Delaware corporation ("Cadus"), pursuant to the
terms of an


                                       4
<PAGE>   5
Asset Purchase Agreement (the "Asset Purchase Agreement") dated the same date.
The assets purchased (the "Assets") include (a) certain assets associated with
certain of Cadus' research programs (including the GPCR Directed Chemistry
Program and a collaboration with Solvay Pharmaceuticals B.V.), (b) Cadus'
compound library, (c) the purchase or license of certain intellectual property
rights, and (d) certain furniture, equipment, inventory, and supplies. Several
assets were retained by Cadus, including (a) monies in escrow in connection with
the judgment of SIBIA Neurosciences, Inc. against Cadus, (b) cash and accounts
receivable, (c) Cadus' Living Chip Technology, (d) Cadus' Functional Genomics
Program, and (e) Cadus' Research Collaboration and License Agreement with
SmithKline Beecham Corporation (the "SmithKline Research Agreement").
Forty-seven Cadus employees, consisting of thirty-six employed in science and
eleven employed in administration and support, were hired by the Company. The
Company intends to continue to utilize some of the Assets in the GPCR Directed
Chemistry Program and the collaboration with Solvay Pharmaceuticals B.V., but
expects to deploy the balance of the Assets in other research areas.

         The purchase price for the Assets was $1.5 million in cash plus an
additional $74,096 in cash for certain prepaid expenses plus the assumption of
certain liabilities, including liabilities under Cadus' facility lease (the
"Facility Lease") in Tarrytown, New York (approximately 45,569 square feet) as
of July 1, 1999 (approximately $898,249 in rental payments per annum through
December 31, 2002) and an equipment lease with GECC Capital Corporation
("GECC"). On August 23, 1999, OSI elected to payoff the GECC lease in exchange
for a payment of $2.8 million and obtained ownership of the fixed assets covered
by the lease agreement. On September 21, 1999, Cadus reimbursed the Company
$308,000 in exchange for those fixed assets that have been retained by Cadus for
its own use. The source of the cash portion of the purchase price and the
subsequent decision to payoff the lease agreement with GECC was the Company's
existing cash resources. Liabilities assumed will be paid from such cash
resources and working capital.

         In connection with the acquisition, the Company entered into the
following additional agreements with Cadus: (a) a Patent License Agreement, (b)
a Technology License Agreement, and (c) a Software License Agreement, pursuant
to which the Company obtained non-exclusive licenses for the use and practice of
certain of Cadus' patents, Cadus' technology and Cadus' software programs,
respectively. The Company and Cadus also entered into another Patent License
Agreement under which the Company will license back to Cadus on a non-exclusive
basis certain of the patents which were assigned to the Company as part of the
acquisition.

         In connection with the acquisition, the Company adopted a Non-Qualified
Stock Option Plan for Former Employees of Cadus (the "Cadus Stock Plan") to
induce certain former employees of Cadus to accept employment with the Company.
The Company granted options to purchase an aggregate of 415,000 shares of common
stock of the Company at a purchase price of $5.00 per share. These options
become exercisable on July 30, 2000. The Asset Purchase Agreement and the Cadus
Stock Plan are attached hereto as Exhibits 2.1 and 2.2, and are incorporated
herein by reference.

         (b)      Financial Statements of Business Acquired

         The audited financial statements of Cadus as of December 31, 1998 and
1997 for each of the years in the three-year period ended December 31, 1998 are
filed herewith as Exhibit 99.1.

         (c)      Pro Forma Financial Information

         The unaudited pro forma condensed combined financial information
related to the Cadus acquisition is filed herewith as Exhibit 99.2. The
unaudited pro forma condensed combined financial statements combine the
historical balance sheets and statements of operations of the Company and Cadus
giving effect to the asset acquisition using the purchase method of accounting
for a business combination.

         Cadus' year-end is December 31. The unaudited pro forma condensed
combined statement of operations for the year ended September 30, 1998 includes
the audited consolidated statement of operations of the Company for the year
ended September 30, 1998 and the audited statement of operations of Cadus for
the year ended December 31, 1998. The unaudited pro forma condensed combined
statement of operations for the nine months ended June 30, 1999 includes the
Company's unaudited consolidated statement of operations for the nine months
ended June 30, 1999 and the combination of the unaudited statements of
operations of Cadus for the three months ended December 31, 1998 and the six
months ended June 30, 1999.

         The unaudited pro forma condensed combined balance sheet gives effect
to the acquisition as if it had occurred on June 30, 1999. The unaudited pro
forma condensed combined statements of operations for the fiscal year ended
September 30, 1998 and the nine months ended June 30, 1999 assume the asset
acquisition was effected on October 1, 1997.

         The unaudited pro forma condensed combined financial statements were
prepared by utilizing the accounting principles of the respective entities as
outlined in each entity's historical financial statements. The pro forma
adjustments are based upon available information and certain assumptions that
the Company believes are reasonable under the circumstances. The unaudited pro
forma condensed combined financial information is provided for illustrative
purposes only. The Company and the acquired research operations of Cadus may
have performed differently had they always been combined. The unaudited pro
forma condensed combined financial information may not be indicative of the
historical results that would have been achieved had the Company and the
acquired research operations always been combined nor the future results that
the Company will experience after the acquisition.

         The information is only a summary and should be read in conjunction
with the Company's historical consolidated financial statements and related
notes contained in the annual reports and other information that was previously
filed with the Securities and Exchange Commission.

                          Independent Auditors' Report


The Board of Directors and Stockholders
Cadus Pharmaceutical Corporation:

We have audited the accompanying balance sheets of Cadus Pharmaceutical
Corporation (the Company) as of December 31, 1998 and 1997, and the related
statements of operations, stockholders' equity, and cash flows for each of the
years in the three-year period ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cadus Pharmaceutical
Corporation as of December 31, 1998 and 1997, and the results of its operations
and its cash flows for each of the years in the three-year period ended December
31, 1998, in conformity with generally accepted accounting principles.

                          Notes to Financial Statements
                        December 31, 1998, 1997 and 1996

(1)    Organization and Basis of Preparation

       Cadus Pharmaceutical Corporation (the "Company") was incorporated on
       January 23, 1992, under the laws of the State of Delaware. The Company is
       a biotechnology Company engaged in genomics research and the discovery of
       novel small molecule therapeutics.

       The Company has accumulated a loss of $43.5 million from January 23,
       1992, (date of inception) to December 31, 1998. Management intends to
       continue research toward the development of commercial products in order
       to generate future revenues from license fees, royalties, direct sales
       and performance of contract research. The Company has financed its
       operations through the sale of common stock in the public market, the
       sale of convertible preferred stock and through revenues resulting from
       research funding provided by its collaborative partners (note 8).

       The Company is at an early stage of development and therefore faces
       certain risks and uncertainties which are present in an emerging
       biotechnology company. The Company's yeast-based and signal transduction
       technologies are novel as drug discovery methods and have not yet been
       shown to be successful in the development of any commercialized drug. The
       Company has not completed development of any drugs and does not expect
       that any drugs resulting from its and its collaborative partners'
       research and development efforts will be commercially available for a
       significant number of years, if at all. The Company is relying on its
       collaborative partners to fund a substantial portion of its research
       operations over the next several years. Through December 31, 1998, the
       Company had entered into three collaborative arrangements, however there
       can be no assurance that the Company will be able to establish additional
       collaborative arrangements, or that these contracts will continue to be
       renewed, or that any renewal will be made on terms favorable to the
       Company. SmithKline Beecham and Solvay Pharmaceuticals may terminate
       their respective collaboration agreements for nonperformance by the
       Company under certain circumstances, which termination would result in
       the Company losing its research funding from each of them. The
       collaboration arrangement with Bristol-Myers Squibb will expire in July
       1999. The loss of research funding from SmithKline Beecham or Solvay
       Pharmaceuticals, or failure by Solvay Pharmaceuticals or SmithKline
       Beecham to provide research funding to the Company, could have a material
       adverse effect on the Company's business, financial condition and results
       of operations.

       In addition, the Company faces risks and uncertainties regarding the
       future profitability of the Company, ability to obtain additional
       funding, protection of patents and property rights, uncertainties
       regarding the Company's technologies including risks and uncertainties
       relating to the Company's development and commercial testing of
       alternative readout methodologies to replace that found to infringe a
       patent of SIBIA Neurosciences, Inc. ("SIBIA") (see note 3), risks and
       uncertainties relating to the Company's ongoing litigation with SIBIA
       including uncertainties relating to the outcome of appeals and the
       re-examination of SIBIA's patent at issue in the litigation, competition
       and technological change, government regulations including the need for
       product approvals and the changing health care marketplace, and
       attracting and retaining key officers, employees and consultants.

                          Notes to Financial Statements
                        December 31, 1998, 1997 and 1996


(2)    Significant Accounting Policies

       (a)    Development Stage Enterprise

              Through December 31, 1996, the Company reported as a development
              stage enterprise in accordance with the Financial Accounting
              Standards Board's ("FASB") Statement of Financial Accounting
              Standards ("SFAS") No. 7, "Accounting and Reporting by Development
              Stage Enterprises". Management believes it has established major
              scientific and research collaborations and that these
              collaborations have generated significant revenues. Therefore,
              beginning with the year ended December 31, 1997, the Company no
              longer reports as a development stage enterprise.

       (b)    Cash Equivalents

              The Company considers all highly liquid investments with original
              maturities of three months or less when purchased to be cash
              equivalents. Included in restricted and unrestricted cash, at
              December 31, 1998 and 1997, there was cash equivalents of
              $13,937,939 and $36,571,433, respectively.

       (c)    Fixed Assets

              Fixed assets are stated at cost. Depreciation of equipment and
              furniture and fixtures is calculated using the straight-line
              method over estimated useful lives of five to seven years.
              Leasehold improvements are amortized on a straight-line basis over
              the lesser of the estimated useful lives of the improvements or
              the remaining term of the lease.

       (d)    Other Assets, Net

              Other assets include capitalized patent costs that are amortized
              on a straight-line basis over fifteen years. At December 31, 1998
              and 1997, accumulated amortization is $156,958 and $78,406,
              respectively.

       (e)    Income Taxes

              Income taxes are accounted for under the asset and liability
              method. Deferred tax assets and liabilities are recognized for the
              future tax consequences attributable to differences between the
              financial statement carrying amounts of existing assets and
              liabilities and their respective tax bases and operating loss and
              tax credit carryforwards. Deferred tax assets and liabilities are
              measured using enacted tax rates expected to apply to taxable
              income in the years in which those temporary differences are
              expected to be recovered or settled. The effect on deferred tax
              assets and liabilities of a change in tax rates is recognized in
              income in the period that includes the enactment date.

                          Notes to Financial Statements
                        December 31, 1998, 1997 and 1996


       (f)    Research and Development

              Research and development costs are expensed as incurred and
              include direct costs of research scientists and supplies and an
              allocation of shared facilities, services and overhead.

       (g)    Revenue Recognition

              The Company has entered into research agreements that provide for
              the payment of nonrefundable fees during the term of the research
              programs. In addition, the agreements provide for payment of fees
              when certain milestone events have occurred. These fees are
              reflected as revenue when earned, as related costs are incurred or
              when milestone events have occurred.

              Revenue recognized in the accompanying statements of operations is
              not subject to repayment. Revenue received that is related to
              future performance under such contracts is deferred and recognized
              as revenue when earned.

       (h)    Net Loss Per Share

              All common share data has been restated to give effect to a
              one-for-three reverse stock split effected on July 18, 1996 (see
              note 10).

              At December 31, 1997, the Company adopted the provisions of
              Statement of Financial Accounting Standards No. 128, Earnings Per
              Share. Basic net loss per share as of December 31, 1998 and 1997
              is computed by dividing the net loss by the weighted average
              number of common shares outstanding. Diluted net loss per share is
              the same as basic net loss per share since the inclusion of
              potential common stock equivalents (stock options and warrants) in
              the computation would be anti-dilutive.

       (i)    Use of Estimates

              The preparation of financial statements in conformity with
              generally accepted accounting principles requires management to
              make estimates and assumptions that affect the reported amounts of
              assets and liabilities and disclosure of contingent assets and
              liabilities at the date of the financial statements and the
              reported amounts of revenues and expenses during the reporting
              period. Actual results could differ from those estimates.

       (j)   Fair Value of Financial Instruments

              For cash and accounts payable, the carrying amount approximates
              the fair value because of the short maturities of those
              instruments.

                          Notes to Financial Statements
                        December 31, 1998, 1997 and 1996


       (k)    Stock-Based Compensation

              SFAS No. 123 "Accounting for Stock-Based Compensation" establishes
              a fair value based method for accounting for stock-based
              compensation plans and for the measurement basis of transactions
              in which an entity acquires goods or services from non-employees
              in exchange for equity instruments. SFAS No. 123 requires that
              reporting entities either elect expense recognition or its
              disclosure-only alternative for stock-based employee compensation.
              During 1996, the Company adopted SFAS No. 123 and has elected to
              continue measuring stock-based employee compensation cost in
              accordance with the intrinsic value based method of Accounting
              Principles Board ("APB") Opinion No. 25 "Accounting for Stock
              Issued to Employees". Therefore, the Company has included in the
              notes to the financial statements pro forma net income and pro
              forma earnings per share using the fair value based method for the
              year ended December 31, 1998 with comparable disclosures for the
              years ended December 31, 1997 and 1996.

(3)    Patent Litigation

       In July 1996, SIBIA Neurosciences, Inc. ("SIBIA") commenced a patent
       infringement action against the Company alleging infringement by the
       Company of a patent concerning the use of cells, engineered to express
       any type of cell surface receptor and a reporter gene, used to report
       results in the screening of compounds against target assays and seeking
       injunctive relief and monetary damages. After trial, on December 18,
       1998, the jury issued a verdict in favor of SIBIA and awarded SIBIA $18.0
       million in damages. On January 29, 1999, the United States District Court
       granted SIBIA's request for injunctive relief that precludes the Company
       from using the method claimed in SIBIA's patent. On February 26, 1999,
       the United States District Court denied the Company's motions to set
       aside the jury verdict to grant a new trial and to reduce or set aside
       the $18.0 million damages award by the jury. The Company has appealed the
       judgement. The appeal will be heard by the Court of Appeals for the
       Federal Circuit in Washington, D.C. In order to stay execution pending
       appeal of the $18.0 million judgement obtained by SIBIA, in March 1999,
       the Company deposited $18.5 million in escrow to secure payment of the
       judgement in the event the Company were to lose the appeal. Such $18.5
       million was classified, as of December 31, 1998, as "restricted cash
       noncurrent" and the Company's "cash and cash equivalents" was reduced by
       $18.5 million. The Company recorded a reserve for litigation damages of
       $18.5 million in the accompanying statement of operations for the year
       ended December 31, 1998.

       In January 1999, the U.S. Patent and Trademark Office granted the
       Company's request to re-examine the patent issued to SIBIA that was the
       subject of the litigation. The re-examination by the Patent Office is
       independent of the litigation and a final decision by the Patent Office
       that SIBIA's patent is invalid would take precedence over the jury
       verdict. There is no evidence that the patent office will find SIBIA's
       patent to be invalid.

       Depreciation and amortization expense for the years ended December 31,
       1998, 1997 and 1996 was approximately $914,000, $1,283,000 and $839,000,
       respectively.

(5)    Related Party Transactions

       During 1998, the Company loaned $15,000 to Dr. Charles Woler, the Chief
       Executive Officer of the Company. The loan bears interest at 5.5% per
       annum. Principal and interest are repayable in monthly installments of
       $453 over three years. At December 31, 1998, the outstanding balance of
       the loan was $13,452.

       In September 1998, Dr. James Broach, a director of the Company, entered
       into a five month employment arrangement with the Company pursuant to
       which he worked full time at the Company and was compensated at the rate
       of $20,000 per month. The Company also granted Dr. Broach an option to
       purchase 50,000 shares of common stock at an exercise price of $2.75 per
       share. The option vests in increments of 10,000 or 20,000 shares upon the
       achievement of specific milestones. In connection with the employment
       arrangement, the Company guaranteed the payment of a $286,000 loan made
       to Dr. Broach by a third-party and secured its guarantee obligation with
       cash collateral of $286,000 which is included in restricted cash on the
       balance sheet. Dr. Broach indemnified the Company from any liabilities
       arising from its guarantee and pledged securities owned by him to secure
       his indemnification obligation.

       See note 6 for further discussion of transactions with related parties.

(6)    Investments in Other Ventures

       In December 1996, the Company issued a $150,000 promissory note bearing
       interest at 7% per annum in exchange for a 42% limited partnership
       interest in Laurel Partners Limited Partnership ("Laurel"), a limited
       partnership of which a shareholder of the Company is the general partner.
       An interest payment of $10,500 was accrued at December 31, 1997 and paid
       in January 1998. The principal amount and interest accrued thereon was
       paid in

                        December 31, 1998, 1997 and 1996


       December 1998. In addition, the Company purchased for $160,660 in cash, a
       47% limited partnership interest in Laurel from Tortoise Corporation, a
       corporation wholly-owned by the shareholder. Laurel's purpose is to
       invest, directly or indirectly, in securities of biotechnology companies.
       The Company has the right to require the shareholder to match any future
       investment made by the Company in Laurel up to an aggregate investment on
       the part of the shareholder of $5.0 million. This right expires on the
       earlier of December 31, 1999 or such time that neither the shareholder
       nor one of his affiliates is the general partner of Laurel. The Company
       is not required to make any additional investment in Laurel. The
       investment is accounted for under the equity method with the recognition
       of losses limited to the Company's capital contributions. For the years
       ended December 31, 1998 and 1997, the Company recognized gains of $7,968
       and losses of $173,964, respectively, related to the investment. The
       remaining investment in Laurel of $144,664 is included in investments in
       other ventures on the balance sheet.

       In May 1997, the Company purchased $2.0 million of convertible preferred
       stock in Axiom Biotechnologies Inc. ("Axiom"), representing approximately
       26% of the outstanding shares of Axiom on an as converted basis. As part
       of the arrangement, Axiom agreed to deliver and license to the Company
       its first High Throughput Pharmacology System (HT-PS(TM)). The Company
       purchased an additional $2.0 million of convertible preferred stock in
       Axiom on June 5, 1998, after the Company received and accepted Axiom's
       HT-PS(TM). The Company also made a payment to Axiom for the HT-PS(TM)
       which is included in fixed assets in the accompanying balance sheet at
       December 31, 1998. The additional investment increased the Company's
       equity interest in Axiom to approximately 30% of Axiom's outstanding
       shares on an as converted basis, after taking into account an investment
       in Axiom by JAFCO Co., Ltd., ("JAFCO"), an affiliate of the Nomura Group.
       The Company's investment is accounted for under the equity method with
       the Company recognizing 100% of Axiom's net losses prior to the JAFCO
       investment and 50% after such investment. Such percentage represents the
       extent to which the Company is deemed to be funding Axiom's losses. For
       the years ended December 31, 1998 and 1997, the Company recognized
       $1,152,116 and $658,467, respectively, in losses generated by Axiom. The
       remaining investment in Axiom of $2,189,417 is included in investments in
       other ventures on the balance sheet.

(7)    Income Taxes

       Deferred tax assets of approximately $19,582,000 and $7,204,000 at
       December 31, 1998 and 1997, respectively, relate principally to tax net
       operating loss carryforwards of $21,459,000 and $13,933,000 and research
       credit carryforwards of $2,111,000 and $1,212,000 at December 31, 1998
       and 1997, respectively and also to the current litigation reserve
       pending of $18.5 million. An offsetting valuation allowance has been
       established for the full amount of the deferred tax assets to reduce such
       assets to zero, as a result of the significant uncertainty regarding
       their ultimate realization. The aggregate valuation allowance increased
       $12,378,000 and $3,417,000 during the periods ended December 31, 1998 and
       1997, respectively.

       The Company's net operating loss carryforwards and research and
       development tax credit carryforwards noted above expire in various years
       from 2008 to 2018. The Company's ability to utilize such net operating
       loss and research and development tax credit

       carryforwards is subject to certain limitations due to ownership changes,
       as defined by rules enacted with the Tax Reform Act of 1986.

       The Company is subject to New York State tax on capital.

(8)    Research Collaboration and License Agreements

       Since July 1994, the Company has been a party to a Research Collaboration
       and License Agreement with Bristol-Myers Squibb Company ("BMS") pursuant
       to which BMS agreed to provide research funding to the Company during the
       term of the research collaboration. The research collaboration expires in
       July 1999. In addition, BMS is obligated to make payments to the Company
       upon the achievement of certain scientific and commercial milestones and
       to pay royalties on sales of products developed under the agreement.

       In July 1996, BMS purchased $2.5 million of the Company's common stock in
       the Company's initial public offering.

       Since November 1995, the Company has been a party to a Research
       Collaboration and License Agreement with Physica B.V., a subsidiary of
       Solvay Pharmaceuticals B.V. ("Solvay") pursuant to which Solvay agreed to
       provide research funding to the Company during the term of the research
       collaboration. The research collaboration expires in November 2000 unless
       extended at the option of Solvay. In addition, Solvay is obligated to
       make payments to the Company upon the achievement of certain drug
       development milestones and to pay royalties on sales of products
       developed under the agreement. The Company has reserved the right to use
       certain hybrid yeast cells that are part of the research program for its
       own benefit in the discovery of drugs relating to cancer, autoimmune,
       allergic and inflammatory diseases, with certain specific exclusions. The
       Company is required to make payments to Solvay upon the achievement by
       the Company of certain drug development milestones and to pay Solvay
       royalties on the sale of such drugs.

       In July 1996, Solvay purchased $5.0 million of the Company's common stock
       in the Company's initial public offering.

       Both BMS and Solvay had purchased convertible preferred stock of the
       Company. See note 10 for discussion of the conversion of the convertible
       preferred stock to common stock.

       In February 1997, the Company entered into a drug discovery collaboration
       and license agreement with SmithKline Beecham p.l.c. and SmithKline
       Beecham Corporation ("SmithKline Beecham"). During the term of the
       research collaboration, which expires in February 2002, the Company will
       seek to identify ligands and to elucidate the function of orphan G
       protein-coupled receptors included within the collaboration and create
       high-throughput screens to discover small molecular agonists and
       antagonists to these receptors.

       During the term of the collaboration, SmithKline Beecham is required to
       provide the Company with research funding and certain other payments. In
       February 1998, SmithKline Beecham paid the Company a one-time $2.0
       million technology development fee.

                        December 31, 1998, 1997 and 1996


       SmithKline Beecham is also required to make payments to the Company upon
       the achievement of certain research milestones and upon the achievement
       by SmithKline Beecham of certain drug development milestones. In January
       1999, the Company achieved its first research milestone in the
       collaboration, and received a $1.0 million dollar payment therefor (see
       footnote 16). SmithKline Beecham is also required to pay the Company
       royalties on the sale of drugs developed through the use of the Company's
       drug discovery technologies. The Company has co-promotion rights in North
       America for certain products that may result from the collaboration and
       rights to certain potential products that SmithKline Beecham may choose
       not to develop.

       SmithKline Beecham has the right to extend the term of the collaboration
       for between two and five years by notice to the Company given prior to
       February 25, 2001. SmithKline Beecham has the right to terminate the
       research collaboration (i) after August 25, 1999, if the Company fails to
       meet certain scientific objectives in connection with the conduct of the
       research collaboration or (ii) if the Company fails to perform its
       obligations in the conduct of the research collaboration in any material
       respect and does not cure such failure within a period of 60 days after
       receiving notice thereof. In the event of such termination, SmithKline
       Beecham has no further obligation to provide the Company with funding for
       the research collaboration.

       In February 1997, the Company and SmithKline Beecham Corporation entered
       into a stock purchase agreement pursuant to which the Company has the
       option to sell to SmithKline Beecham Corporation (i) shares of the
       Company's common stock having a then fair market value of $5.0 million
       during a 90-day period commencing on February 25, 1998 and (ii) shares of
       the Company's common stock having a then fair market value of $5.0
       million, during a 90-day period commencing on the date certain scientific
       objectives are achieved (subject to the Company achieving such objectives
       prior to the August 25, 1999 and meeting certain financial requirements).
       In May 1998, the Company exercised its first option and sold 660,962
       shares of its common stock to SmithKline Beecham p.l.c. and SmithKline
       Beecham Corporation for approximately $7.56 per share or an aggregate
       consideration of $5.0 million. In addition, SmithKline Beecham
       Corporation has the right, at its option, to purchase up to $5.0 million
       worth of shares of the Company's common stock at 150% of the then fair
       market value in lieu of making certain research milestone payments. The
       Company granted SmithKline Beecham Corporation certain registration
       rights with respect to shares of the Company's common stock which
       SmithKline Beecham Corporation may purchase pursuant to the stock
       purchase agreement.

       For the year ended December 31, 1998, the Company received and recognized
       $10.6 million in research revenue and the one-time $2.0 million
       technology development fee from SmithKline Beecham. For the years ended
       December 31, 1997 and 1996 the Company recognized $8.8 million and $6.5
       million, respectively, in research revenue.

(9)    Sponsored Research and License Agreements

       In January 1998 and January 1999, the Company entered into sponsored
       research agreements with Massachusetts Institute of Technology ("M.I.T.")
       pursuant to which M.I.T. will use its expertise in micro-robotics to
       co-develop the LivingChip(TM), a novel drug

       discovery screening tool that would miniaturize and automate the
       Company's proprietary hybrid yeast cell technology. If developed, the
       LivingChip(TM) would ultimately accommodate at least 100,000 yeast-based
       drug discovery assays on a single CD-sized synthetic disc and would
       permit the testing of thousands of compounds on multiple assays at the
       individual scientist's lab bench. The Company provided M.I.T. with full
       research funding for 1998 and partial funding for 1999 and has the option
       to extend the arrangement through the remainder of 1999. The Company also
       entered into a license agreement with M.I.T. pursuant to which the
       Company obtained exclusive worldwide rights, for use in pharmaceutical,
       animal health and agricultural businesses, to the technology developed
       under the sponsored research arrangement. In order to maintain its
       exclusive license, the Company must provide M.I.T. with specified levels
       of research funding in 1998 and 1999 and make a minimum level of
       expenditures thereafter to commercialize the technology until the
       technology is commercialized. The Company is required to pay M.I.T. an
       annual license fee, royalties on the sale or lease of LivingChip(TM)
       systems, royalties on the sale of therapeutics and diagnostics developed
       using the LivingChip(TM), royalties on services rendered based on the
       LivingChip(TM), and an annual sublicense fee for each sublicense of the
       LivingChip(TM).

       The Company has entered into several other license and sponsored research
       agreements with various third parties. Generally, the agreements provide
       that the Company will make research payments and will pay license fees
       and/or maintenance payments, in return for the use of technology and
       information and the right to manufacture, use and sell future products.
       These agreements provide for payments based on the completion of
       milestone events, as well as royalty payments based upon a percentage of
       product or assay sales. License fees and maintenance payments, including
       payments made to M.I.T., for the years ended December 31, 1998, 1997 and
       1996, amounted to approximately $2.0 million, $590,000 and $355,000,
       respectively.

(10)   Equity Transactions

       In July 1996, the Company effected a one-for-three reverse common stock
       split and changed the par value of the common stock to $.01 from $.001.
       All common stock and option data have been restated to give effect to
       this reverse stock split and change in par value for all periods
       presented.

       In July 1996, the Company completed an initial public offering of
       2,750,000 shares of common stock at $7.00 per share. The Company received
       proceeds, net of underwriting discounts, commissions and other initial
       public offering expenses of $17,176,624. Following the initial public
       offering, all outstanding shares of the Series A and Series B preferred
       stock were converted into an aggregate of 7,551,514 shares of common
       stock. Upon conversion, the entire class of convertible preferred stock
       of the Company was canceled and withdrawn from the authorized capital
       stock of the Company. As a result, upon completion of the offering, the
       Company's authorized capital consisted of 35,000,000 shares of common
       stock.

       In August 1996, the Company sold an additional 412,500 shares of common
       stock at $7.00 per share pursuant to the exercise by the underwriters of
       an over-allotment option granted

       to them. The Company received proceeds, net of underwriting discounts and
       commissions, of $2,685,375.

       In May 1998, the Company sold 660,962 shares of its common stock to
       SmithKline Beecham p.l.c. and SmithKline Beecham Corporation for
       approximately $7.56 per share or an aggregate consideration of $5.0
       million.

(11)   Stock Options

       The 1993 Stock Option Plan ("the 1993 Plan") was adopted in January 1993.
       The 1993 Plan provides for the grant of options to reward executives,
       consultants and employees in order to foster in such personnel an
       increased personal interest in the future growth and prosperity of the
       Company. The options granted under the 1993 Plan may be either incentive
       stock options or nonqualified options. An aggregate of 666,667 common
       shares were reserved for issuance under the 1993 Plan.

       Options granted under the 1993 Plan expire no later than ten years from
       the date of grant. The option price is required to be at least 100% and
       85% of the fair market value on the date of grant as determined by the
       Board of Directors for incentive stock options and nonqualified options,
       respectively. The options generally become exercisable according to a
       schedule of vesting as determined by the Compensation Committee of the
       Board of Directors. The schedule prescribes the date or dates on which
       the options become exercisable, and may provide that the option rights
       accrue or become exercisable in installments over a period of months or
       years.

       Effective May 10, 1996, the 1993 Plan was replaced by the 1996 Incentive
       Plan ("the 1996 Plan") with respect to all future awards to the Company's
       employees and consultants. However, awards made under the 1993 Plan will
       continue to be administered in accordance with the 1993 Plan.

       At December 31, 1998, the range of exercise prices and weighted-average
       remaining contractual life of outstanding options was $1.37 to $3.51 and

       At December 31, 1998 and 1997, the number of options exercisable was
       432,383 and 422,553, respectively and the weighted-average exercise price
       of those options was $1.62 and $1.73, respectively.

       The Company entered into stock option agreements not pursuant to any plan
       with certain directors, employees, founders and consultants. These
       options generally become exercisable according to a schedule of vesting
       as determined by the Compensation Committee of the Board of Directors.
       The options become exercisable in installments over a period of months or
       years. As of December 31, 1998, an aggregate of 597,257 common shares was
       reserved for issuance pursuant to such stock option agreements.

       In November 1996, the Compensation Committee granted to certain directors
       then in office an option to purchase 12,000 shares of common stock at an
       exercise price of $6.75 per share. Each stock option grant is exercisable
       in four cumulative annual installments of 3,000 shares commencing in
       November 1997 and expires in November 2006.

        The 1996 Plan was adopted in May 1996. The options granted under the
        1996 Plan may be either incentive stock options or nonqualified options.
        In December 1996, the maximum number of shares of common stock that may
        be the subject of awards under the 1996 Incentive Plan was increased
        from 333,334 to 833,334 (plus any shares that are the subject of
        canceled or forfeited awards) by the Board of Directors and such
        increase was approved by the stockholders of the Company in June 1997.

        Options granted under the 1996 Plan expire no later than ten years from
        the date of grant. The option price is required to be at least 100% of
        the fair value on the date of grant as determined by the Board of
        Directors for incentive stock options. The options generally become
        exercisable according to a schedule of vesting as determined by the
        Compensation Committee of the Board of Directors. The schedule
        prescribes the date or dates on which the options become exercisable,

        installments over a period of months or years.

       statements. If the Company had elected to recognize compensation cost
       based on the fair value of the options granted at the grant date under

       Pro forma net loss reflects only options granted since 1995. Therefore,
       the full impact of calculating compensation cost for stock options under
       SFAS No. 123 is not reflected in the pro forma net loss amounts presented
       above because compensation cost is reflected over the options' vesting
       period and compensation cost for options granted prior to January 1, 1995
       is not considered.

       The fair value of each option grant is estimated on the date of grant
       using the Black-Scholes option-pricing model with the following
       assumptions:

(13)   Commitments and Contingencies

       Lease Commitments

       In October 1994, the Company entered into a sublease agreement with Union
       Carbide Corporation to sublease laboratory and office space in Tarrytown,
       New York. The term of this agreement is for a period of approximately
       three years commencing on May 15, 1995 and expiring on December 30, 1997.
       Pursuant to this agreement, the Company received the first four months
       rent free, which was amortized through December 30, 1997 so as to produce
       a level amount of rent expense over the life of the lease. The
       unamortized portion was included in accrued expenses and other current
       liabilities in the accompanying balance sheet.

       During 1997, the Company exercised its option to lease these facilities
       directly from the landlord for a five-year period commencing January 1,
       1998. Upon the signing of the lease, the landlord paid the Company
       $140,000 which is included in accrued expenses and is being amortized
       over the life of the lease. From October 1, 1997 through December 31,
       1998, the Company temporarily leased approximately 7,000 square feet from
       the landlord. The Company leased an additional 18,528 square feet of
       contiguous space during 1998 under the same terms as the original lease
       with the landlord. The Company also has an option to renew such lease for
       a five-year period commencing on January 1, 2003.

       In November 1994, the Company entered into an agreement to sublease
       laboratory and office space, in Lakewood, Colorado, from Colorado
       Bio/Medical Venture Center ("CBVC") for a period of 21 months ending on
       July 9, 1996. In March 1996, the Company extended the sublease agreement
       for eight additional months, therefore extending the lease expiration
       date to March 9, 1997 at which time the Company became a month-to-month
       tenant. The Company relocated its Lakewood, Colorado operations to New
       York and terminated its lease with CBVC on December 31, 1997. The
       approximate cost of the relocation was $349,000.

       Future minimum lease payments for each of the five years subsequent to
       December 31, 1998 and thereafter are $898,249 per year from 1999 through
       the year ended December 31, 2002.

       Rent expense, excluding utility and operating costs, for the years ended
       December 31, 1998, 1997 and 1996 amounted to approximately $728,407,
       $759,800 and $620,600, respectively.

       Equipment Lease Line of Credit

       In November 1997, the Company signed a $3.5 million Master Lease
       Agreement ("Master Lease") with General Electric Capital Corporation
       ("GECC"). Under the agreement, the Company purchases equipment and then
       enters into a sale-leaseback arrangement with GECC whereby the Company
       sells the equipment to GECC and then leases back the equipment for a
       period of 37 months. The lease arrangements are considered operating
       leases for financial reporting purposes. Any gains recognized on the
       difference between

       the equipment's book value and sale price are booked to deferred revenue
       and recognized over the life of the lease.

       Pursuant to its Master Lease with GECC, the Company must maintain
       unrestricted cash, cash equivalents and investment grade securities (the
       "Cash Equivalents") of at least $10,000,000. In March 1999, the Company
       ceased to maintain Cash Equivalents of at least $10,000,000. Under the
       Master Lease, by April 15, 1999, the Company must notify GECC of the
       amount of Cash Equivalents of the Company and that the Company is not in
       compliance with the Master Lease. GECC may then require the Company to
       deliver to GECC within fifteen (15) days an irrevocable standby letter of
       credit (the "Letter of Credit") in the amount of the "stipulated loss
       value" of the equipment covered by the Master Lease (the "Equipment"),
       which amount is currently $3.1 million to secure the Company's
       obligations under the Master Lease. In order to obtain the Letter of
       Credit, the Company would most likely have to provide to the issuer
       thereof cash collateral in the amount of the Letter of Credit. If the
       Letter of Credit is not delivered, the Company will be in default under
       the Master Lease. If the Company does not cure such default with in
       thirty (30) days after written notice thereof from GECC, GECC may require
       the Company at its own cost and expense, to return the Equipment and to
       pay to GECC the stipulated loss value of the Equipment as liquidated
       damages and any rentals or other sums then due. GECC is not required to
       mitigate damages.

       The Company has made the following drawdowns against the Master Lease:

       The gains totaling $199,830 relating to the sale of the equipment to GE
       Capital were credited to deferred revenue on the balance sheet and are
       being amortized over the life of the individual leases. At December 31,
       1998 and 1997, $45,965 and $3,281, respectively, of the deferred gain was
       recognized as gain on sale of equipment in the accompanying statement of
       operations.

       Future minimum lease payments for each of the three years subsequent to
       December 31, 1998 are $867,569, $861,730 and $439,850, respectively.

(16)   Subsequent Events

       (a) SmithKline Beecham Milestone

       In January 1999, the Company achieved a research milestone in its
       collaboration with SmithKline Beecham Corporation. The milestone involved
       the identification, during 1998, of ligands for orphan G-Protein coupled
       receptors identified from the human genome. The Company received a $1.0
       million payment for achieving the milestone, which payment was recorded
       as revenue in January 1999.

       (b) Asset Purchase Agreement with OSI Pharmaceuticals, Inc. and Cessation
       of Drug Discovery Operations and Research Efforts

       On July 30, 1999, the Company sold to OSI Pharmaceuticals, Inc. ("OSI"),
       pursuant to an asset purchase agreement, its drug discovery programs
       focused on G-protein-coupled receptors, its directed library of
       approximately 150,000 small molecule compounds specifically designed for
       drug discovery in the G-protein-coupled receptor arena, its collaboration
       with Solvay Pharmaceuticals B.V. ("Solvay Pharmaceuticals"), its lease to
       its research facility in Tarrytown, New York together with the furniture
       and fixtures and its lease to equipment in the facility, and its
       inventory of laboratory supplies. Pursuant to such sale transaction, OSI
       assumed the Company's lease to the Company's research facility in
       Tarrytown, New York, the Company's equipment lease with General Electric
       Capital Corporation ("GECC") and the Company's research collaboration and
       license agreement with Solvay Pharmaceuticals. OSI also hired more than
       45 of the Company's scientific and administrative personnel. As
       consideration for the sale, the Company received approximately $1,500,000
       in cash and OSI assumed certain liabilities of the Company relating to
       employees hired by OSI aggregating approximately $150,000. In addition,
       the Company would be entitled to royalties and up to $3.0 million in
       milestone payments on the first product derived from compounds sold to
       OSI or from the collaboration with Solvay Pharmaceuticals. The Company
       licensed to OSI on a non-exclusive basis certain technology solely to
       enable OSI to fulfill its obligations under the collaboration with Solvay
       Pharmaceuticals. The Company also licensed to OSI on a non-exclusive
       basis certain proprietary software and technology relating to chemical
       resins in order to enable OSI to fully benefit from the compounds it
       acquired from the Company.

       The Company is retaining ownership of all its other assets, including its
       core yeast technology for developing drug discovery assays, its
       collection of over 25,000 proprietary yeast strains, human and mammalian
       cell lines, and genetic engineering tools, its program to identify and
       isolate human orphan G protein-coupled receptors and elucidate their
       function, its proprietary software, its genomics databases related to
       G-protein-coupled receptors, the LivingChip program, all assays and
       technologies reverting to it from its collaboration with Bristol-Myers
       Squibb Company, a 30% equity position in Axiom Biotechnologies Inc., the
       Company's current cash and cash equivalents, and the approximately $18.7
       million being held in escrow pending appeal of the verdict in favor of
       SIBIA.

       The Company ceased its drug discovery operations and research efforts for
       collaborators as a result of the transaction. Pursuant to a research
       agreement, OSI will assist the Company in winding up its research efforts
       on behalf of SmithKline Beecham Corporation and SmithKline Beecham p.l.c.
       Consequently, the Company has terminated all employees who were not hired
       by OSI, except for four employees who will work for the Company through
       August 31, 1999 and two officers.

     Pharmaceuticals, Inc. ("OSI") from Cadus Pharmaceutical Corporation
     ("Cadus") in accordance with the Asset Purchase Agreement dated July 30,
     1999 by and between OSI and Cadus (the "Agreement"). The book values of the
     assets acquired and the liabilities assumed by OSI from Cadus are
     summarized as follows:

(2)  Cash paid by OSI in connection with the Agreement summarized as follows:

<TABLE>
<S>                                          <C>
         Purchase price to Cadus             $  1,574
         Professional fees                        700
                                             --------

                                             ========
</TABLE>

     In addition, OSI assumed $150 of certain employee-related liabilities
     resulting in a total acquisition cost of $2,424.

(3)  Allocation of the purchase price to compound library acquired by OSI (see
     note 5 regarding valuation study).

(4)  Allocation of the purchase price to the assembled workforce intangible
     (see note 5 regarding valuation study).

(5)  Represents an estimated charge of $670 for acquired in-process research and
     development costs, net of negative goodwill allocation (see note 6). No tax
     benefit has been reflected in connection with this charge in recognition of
     the uncertainty that any such tax benefits will be realized by OSI based on
     its history of operating losses since OSI's inception. OSI has engaged a
     professional services firm to conduct a valuation study of the assets
     acquired under the Agreement, including a determination of acquired
     in-process research and development costs. This valuation has not yet been
     completed. As a result, the allocation of the purchase price is subject to
     change upon completion of the valuation study, including the estimated
     amount of acquired in-process research and development costs.

     The estimated charge of $670 for acquired in-process research and
     development costs has been reflected as a reduction of stockholders' equity
     in the pro forma condensed combined balance sheet as of June 30, 1999.
<PAGE>   5
     This same charge has been excluded from the pro forma condensed combined
     statement of operations for the year ended September 30, 1998 since the
     charge is non-recurring and directly related to the Agreement.

(6)  Allocation of negative goodwill to reduce noncurrent financial assets on a
     pro rata basis. The determination of negative goodwill and the allocation
     to noncurrent financial assets are summarized as follows:

(7)  Revenues and expenses of activities not assumed by OSI. In accordance with
     the Agreement, OSI assumed the operations of Cadus' facility, including
     lease obligations for the facility and certain research equipment, 47
     research employees and the research program with Solvay Pharmaceuticals
     B.V. The determination of the pro forma employee-related expenses is based
     on the ratio of research employees hired by OSI to the total number of
     Cadus research employees during the pro forma periods. Other research
     costs and administrative expenses were estimated based on the operating
     activities assumed by OSI as a result of the Agreement. No provision for
     income taxes has been made based on the history of the operating losses of
     both OSI and Cadus since their inceptions. A summary of revenue and
     expenses activity acquired by OSI is as follows:
