CADUS CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note - 1 ORGANIZATION AND BASIS OF PREPARATION

Cadus Pharmaceutical Corporation changed its name to Cadus Corporation (the "Company") on June 20, 2003. The change in name was approved by the stockholders of the Company at the Company's Annual Meeting of Stockholders held on June 18, 2003.

The information presented as of June 30, 2003 and for the three and six month periods then ended, is unaudited, but includes all adjustments (consisting only of normal recurring accruals) that the Company's management believes to be necessary for the fair presentation of results for the periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to the requirements of the Securities and Exchange Commission, although the Company believes that the disclosures included in these financial statements are adequate to make the information not misleading. The December 31, 2002 balance sheet was derived from audited consolidated financial statements. These financial statements should be read in conjunction with the Company's annual report on Form 10-K for the year ended December 31, 2002.

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary Cadus Technologies, Inc., organized in December 2001. All inter- company balances and transactions have been eliminated in consolidation.

The results of operations for the six month period ended June 30, 2003 are not necessarily indicative of the results to be expected for the year ending December 31, 2003.

Note - 2 NET LOSS PER COMMON SHARE

For the three and six-month periods ended June 30, 2003 and 2002 basic net loss per share 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 495,975 shares of potential common stock equivalents (stock options and warrants) in the computation for the three and six-month periods ending June 30, 2003 would be anti-dilutive. Diluted net loss per share is the same as basic net loss per share since the inclusion of 609,309 shares of potential common stock equivalents in the computation for the three and six-month periods ending June 30, 2002 would be anti- dilutive.

Note - 3 LICENSING AGREEMENTS

In December 2001, the Company licensed its yeast-based drug discovery technologies on a non-exclusive basis to a major pharmaceutical company. Under the licensing agreement, the Company received an up-front non-refundable fee of $500,000 that was recorded as

CADUS CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

revenue in the December 31, 2001 consolidated statement of operations as the Company has no further involvement with the development of the product. The Company received payment in January 2002. The Company received an additional licensing fee in 2002 of $1,000,000 upon the licensee achieving a research milestone. The licensee is entitled to use the technologies for five years from the date of the agreement. Following the initial five year term, the licensee may renew the license annually upon payment of an annual licensing fee of $250,000.

In February 2000, Cadus licensed to OSI Pharmaceuticals, Inc. ("OSI"), on a non-exclusive basis, its yeast-based drug discovery technologies, including various reagents and its library of over 30,000 yeast strains, and its bioinformatics software. OSI paid to Cadus a license fee of $100,000 and an access fee of $600,000 and in December 2000 a supplemental license fee of $250,000. OSI is also obligated to pay an annual maintenance fee of $100,000 until the earlier of 2010 or the termination of the license. OSI may terminate the license at any time on 30 days prior written notice. During the six-month period ended June 30, 2003 and 2002, Cadus recognized $100,000 of license revenue related to this agreement.

Note - 4 INVESTMENT IN MARKETABLE SECURITIES

The Company had an equity interest in Axiom Biotechnologies, Inc. ("Axiom"). Due to Axiom's operating losses, the Company's investment was written down to $0 at December 31, 2001. On August 30, 2002, Axiom entered into a merger agreement with a wholly- owned subsidiary of Sequenom, Inc. which is publicly traded on the Nasdaq National Market. The Company received 441,446 common shares of Sequenom, Inc. in exchange for its shares in Axiom.

Pursuant to the merger, 102,685 of the Company's 441,446 common shares of Sequenom, Inc. are held in escrow (the "Escrow Shares") for a one-year period. The Escrow Shares are held to secure rights to indemnification, compensation and reimbursement of Sequenom, Inc. and other indemnities as defined in the merger agreement. The value of the Escrow Shares received was recorded as a deferred gain on exchange of equity interest in the accompanying condensed consolidated balance sheet.

Pursuant to the provisions of Statement of Financial Accounting Standards No. 115, "Accounting for Certain Debt and Equity Securities" management deems its investment in Sequenom, Inc. to be available for sale and reports its investment at fair value with net unrealized gains or losses reported in accumulated other comprehensive income (loss) within stockholders' equity. The Company's unrealized gain of $108,403 as of June 30, 2003 on shares received is reflected in accumulated other comprehensive income. The Company's unrealized gain of $32,859 as of June 30, 2003 for Escrow Shares is included in the deferred gain on exchange of equity interest.

Note - 5 ADOPTION OF NEW ACCOUNTING PRONOUNCEMENT

In December 2002, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure" ("SFAS 148"). SFAS 148 provides alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation as originally provided by SFAS No. 123 "Accounting for Stock-Based Compensation". Additionally, SFAS 148 amends the disclosure requirements of SFAS 123 to require prominent disclosure in both the annual and interim financial statements about the method of accounting for stock-based compensation and the effect of the method used on reported results. Pro forma net (loss) would be the same as the reported net (loss) for the three and six months ended June 30, 2003 and 2002 had the fair-value-based method been applied to all outstanding awards, which were fully vested as of December 31, 1999. Therefore, the application of the disclosure portion of this standard had no impact on our consolidated financial statements as of June 30, 2003 and for the three and six months ended June 30, 2003.

On April 22, 2003, the FASB determined that stock-based compensation should be recognized as a cost in the financial statements and that such cost be measured according to the fair value of the stock options. The FASB has not as yet determined the methodology for calculating fair value and plans to issue an exposure draft later this year that could become effective in 2004. We will continue to monitor communications on this subject from the FASB in order to determine the impact on the Company's consolidated financial statements.

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

OVERVIEW

The Company was incorporated in 1992 and until July 30, 1999, devoted substantially all of its resources to the development and application of novel yeast-based and other drug discovery technologies. On July 30, 1999, the Company sold its drug discovery assets and ceased its internal drug discovery operations and research efforts for collaborative partners.

At June 30, 2003, the Company had an accumulated deficit of approximately $33.3 million. The Company's losses have resulted principally from costs incurred in connection with its research and development activities and from general and administrative costs associated with the Company's operations. These costs have exceeded the Company's revenues and interest income. As a result of the sale of its drug discovery assets and the cessation of its internal drug discovery operations and research efforts for collaborative partners, the Company ceased to have research funding revenues and substantially reduced its operating expenses. The Company expects to generate revenues in the future only if it is able to license its technologies.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2003 AND JUNE 30, 2002

REVENUES

There were no revenues for the three months ended June 30, 2003 and 2002.

COSTS AND EXPENSES

General and administrative expenses decreased to $241,152 for the three months ended June 30, 2003 from $277,835 for the same period in 2002. The decrease can be attributed primarily to a decrease in professional and license fees.

For the three months ended June 30, 2003, the Company recognized a gain of $361 in its investment in Laurel Partners Limited Partnership ("Laurel"). The gain for the same period in 2002 was $725.

INTEREST INCOME

Interest income for the three months ended June 30, 2003 was $46,820 compared to interest income of $85,619 for the same period in 2002. This decrease is attributable primarily to lower interest rates earned on invested funds.

NET LOSS

Net loss for the three months ended June 30, 2003 was $193,971 compared to a net loss of $191,491 for the same period in 2002. This increase in net loss can be attributed primarily to a decrease in interest income offset in part by the decrease in professional and license fees.

11

SIX MONTHS ENDED JUNE 30, 2003 AND JUNE 30, 2002

REVENUES

Revenues for the six months ended June 30, 2003 and 2002 were $100,000 which is the annual maintenance fee from OSI Pharmaceuticals, Inc.

COSTS AND EXPENSES

General and administrative expenses decreased to $534,070 for the six months ended June 30, 2003 from $541,545 for the same period in 2002. This decrease can be attributed primarily to a decrease in license fees offset by an increase in shareholder relations.

For the six months ended June 30, 2003, the Company recognized a loss of $2,775 in its investment in Laurel. The gain for the same period in 2002 was $1,407.

INTEREST INCOME

Interest income for the six months ended June 30, 2003 was $100,407 compared to interest income of $180,187 for the same period in 2002. This decrease is attributable primarily to lower interest rates earned on invested funds.

NET LOSS

Net loss for the six months ended June 30, 2003 was $336,438 compared to a net loss of $259,951 for the same period in 2002. This increase in net loss can be attributed primarily to the decrease in interest income.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2003 the Company held cash and cash equivalents of $24.5 million. The Company's working capital at June 30, 2003 was $25.4 million.

The Company believes that its existing capital resources, together with interest income, will be sufficient to support its operations through the end of 2004. This forecast of the period of time through which the Company's financial resources will be adequate to support its operations is a forward-looking statement that may not prove accurate and, as such, actual results may vary. The Company's capital requirements may vary as a result of a number of factors, including the transactions, if any, arising from the Company's efforts to acquire or invest in companies and income-producing assets and the expenses of pursuing such transactions.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's earnings and cash flows are subject to fluctuations due to changes in interest rates primarily from its investment of available cash balances in money market funds with portfolios of investment grade corporate and U.S. government securities. The Company does not believe it is materially exposed to changes in interest rates. Under its current policies the Company does not use interest rate derivative instruments to manage exposure to interest rate changes.

12

Item 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Based on the evaluation of the Company's disclosure controls and procedures conducted as of the period covered by this report on Form 10-Q, the Company's President and Chief Executive Officer, who also performs the functions of a principal financial officer, concluded that the Company's disclosure controls and procedures (as defined in Rules 13a-14(c) and 15d-14(c) promulgated under the Securities Exchange Act of 1934) are effective.
