§ 1

Responsibilities

1. Through the resolution adopted by the Supervisory Board on May 20, 2003, the Chief Executive Officer was appointed as member of the Management Board and as its chairman (CEO) for an additional period of five years, effective June 1, 2003.

2. In conjunction with the other appointed members of the Management Board, the Chief Executive Officer shall conduct the affairs of the Company with the due care and diligence of a prudent and conscientious business manager pursuant to the provisions of law, the Articles of Incorporation, the Rules of Internal Procedure for the Management Board as issued by the Supervisory Board, a plan for the allocation of duties, and this Agreement. In particular, the Chief Executive Officer shall comply with the instructions of the Supervisory Board.

3. The Chief Executive Officer shall always act exclusively for the good of the Company and of any enterprises affiliated with it in the future and shall, to be best of his ability, support and promote its interests and objectives, in particular the enhancement of the Company’s shareholder value.

4. Other responsibilities as described specifically in the appendix are incumbent upon the Chief Executive Officer.

5. The Chief Executive Officer is obligated to assume, upon demand by the Supervisory Board, Supervisory Board mandates or a seat in similar supervisory bodies in other companies that are affiliated with the Company as well as managerial functions at subsidiaries or enterprises affiliated with the Company. He shall resign from such positions at any time upon demand by the Supervisory Board, and no later than upon the termination of his appointment as Chief Executive Officer.

§ 2

Term of Contract

1. This Agreement commences on June 1, 2003, with premature dissolution of the Management Agreement of May 4, 2000. It is entered into for a fixed term of 5 years running to June 1, 2008. The right to termination for cause (§ 12) remains unaffected thereby.

2. By no later than twelve months prior to the expiration of this Agreement, the chairman of the Supervisory Board shall inform the Chief Executive Officer whether the Supervisory Board intends to reappoint the Chief Executive Officer as chief executive officer and whether it is prepared to extend this Service Agreement with him in keeping with the term of the reappointment or to enter into a new contract of employment subject to different terms and conditions. The Chief Executive Officer and the chairman of the Supervisory Board shall thereupon reach an Agreement on a contract of employment acceptable to both sides within 3 months.

3. If the Supervisory Board resolves not to appoint the Chief Executive Officer to a new term in office and has accordingly not made the Chief Executive Officer an offer for the extension of contract under comparable terms and conditions by June 1, 2007, then the Chief Executive Officer is entitled to demand his release, effective December 1, 2007, from all employment obligations with continued payment of his emoluments. Irrespective thereof, this Agreement shall remain in force until June 1, 2008.

Moreover, the Chief Executive Officer shall be paid a one-time settlement in the amount of 200% (two hundred percent) of the total of the last annual salary and of the average of the two annual bonuses last received. This amount shall be paid out on June 1, 2008.

Moreover, all options, convertible bonds, phantom stock, and all rights that carry an entitlement to acquire stock in the Company that have been issued to the Chief Executive Officer up to that time shall vest (“accelerated vesting”). The Chief Executive Officer shall moreover be granted an extension of the period within which stock options, convertible bonds, phantom stock, and all other rights that carry an entitlement to acquire stock in the Company must be exercised, with said extension running to 3 years following the end of the term of contract (extended to June 1, 2011).

§ 3

Remuneration

1. The Chief Executive Officer shall receive for his activity a gross annual salary (base salary) in the amount of

€ 295,136 (two hundred ninety-five thousand one hundred thirty-six EUROS)

plus

$131,875 (one hundred thirty-one thousand eight hundred seventy-five US Dollars),

payable in 12 equal monthly installments.

The annual salary shall be reviewed by the Supervisory Board with regard to a possible increase. No increase is planned for 2003. The next annual review for a possible increase in the gross salary is planned for Q2, 2004. An adjustment of the German share (in EUR) relative to the U.S. share (in U.S. $) of the Chief Executive Officer’s gross salary is possible at any time with the approval of the Supervisory Board, so as to reflect a possible change in the relative amount of time spent by the Chief Executive Officer working for the Company in Germany relative to the USA.

2. Moreover, the Chief Executive Officer shall continue to receive support for maintaining double households (“double-household allowance”) with respect to the second residence in the USA in the amount of US $3,000 (three thousand US Dollars) per month, which shall be paid out in the USA. This amount too shall be reviewed by the Supervisory Board on an annual basis with regard to a possible increase.

3. In addition to the remuneration specified in Paragraphs 1 and 2, the Chief Executive Officer shall receive special remuneration to be decided by the Supervisory Board within the meaning of § 86 AktG (Stock Corporation Act) as additional performance-based compensation (“performance cash bonus”). This “performance cash bonus” shall - in the event of performance by the Chief Executive Officer - be in keeping with the standards of his position and field. However, whether this remuneration will be granted and the amount thereof are at the absolute discretion of the Supervisory Board.

3. In addition to the remuneration defined in Paragraphs 1 through 3, and in addition to the “performance” stock options and/or convertible bonds to be decided by the Supervisory Board on an annual basis, the Chief Executive Officer shall, at the earliest possible time following the

signing of this Agreement, receive as part of his remuneration a one-time amount of 300,000 (three hundred thousand) stock options with a strike price corresponding to the closing price of the GPC Biotech stock on the date of issue of the stock options to the Chief Executive Officer. This presupposes that the new “contingent capital” necessary therefor has been created by the GPC Biotech 2004 General Meeting of Shareholders. The conversion privilege certificated by the stock options shall be exercised in accordance with the applicable option terms. In this regard, the options are subject to a special call right (“vesting”) staggered in annual tranches not to exceed 4 years (i.e., “vesting” of 75,000 options per year). However, the fourth and last tranche of 75,000 stock options shall not vest later than May 30, 2008, and thus one day prior to the end of contract.

5. In the event of a change of control, the Addendum to Service Agreement approved by the Supervisory Board and signed on May 1, 2003 by the Supervisory Board chairman and the Chief Executive Officer enters into force. The definition of “Change of Control” and the associated payments (premature “vesting” of stock options, convertible bonds, phantom stock, other rights that carry an entitlement to acquire stock in the Company, etc., as well as cash payments) are set forth in detail therein. The Addendum to Service Agreement is attached hereto.

With regard to other residual claims under this Service Agreement of June 1, 2003 (upon premature dissolution of this Service Agreement as a result of Change of Control), and the claims under the Addendum to Service Agreement of May 1, 2003, upon a Change of Control, the better set of terms and conditions enters into force (the better set of terms and conditions with regard to cash payments, premature “vesting” of stock options, convertible bonds, etc., and extended period for exercising the options, convertible bonds, etc.), but not both (i.e., the claims under the two Agreements are not combined).

6. The entirety of the Chief Executive Officer’s claim arising from his activity shall be deemed settled by the remuneration pursuant to the preceding paragraphs.

§ 4

Other Benefits

1. The Company is obligated to reimburse the Chief Executive Officer - where applicable, in accordance with the Internal Guidelines of the Company - for necessary and reasonable expenses, including travel and entertainment costs. The expenses shall in each case be documented in accordance with tax law, unless flat-rate amounts permitted under tax law are settled.

§ 5

Vacation

1. The Chief Executive Officer is entitled to an annual vacation of 30 working days.

2. The schedule shall be decided in coordination with the Company, taking into account the business interests of the Company.

3. If the Chief Executive Officer is unable to use some or all of his vacation time by year’s end owing to business or personal reasons, he remains entitled to said vacation time until June 30 of

the subsequent year. If some or part of the vacation time cannot be used by that date owing to business reasons, the vacation claim lapses. There is no entitlement to compensation for unused vacation time.

4. If some or all of the vacation time cannot be granted owing to termination of the employment relationship, a corresponding settlement shall be paid to the Chief Executive Officer.

§ 6

Remuneration During Illness

1. In the event of illness, monthly remuneration in the amount of 100% of the monthly remuneration pursuant to § 3, Paragraphs 1 and 2 shall continue to be paid for a period of 6 months. The continued payment of emoluments shall not extend beyond the termination of this Service Agreement.

2. Any payments made by third parties, such as those resulting from liability claims or health insurance coverage, shall be credited to payments paid by the Company insofar as the total of such payments and the payments by the Company exceeds the net emoluments that the Chief Executive Officer would receive pursuant to § 3 if he were not unable to work.

§ 7

Duties and Secondary Activity

1. The Chief Executive Officer shall devote his entire working capacity and all of his knowledge, experience, and know-how to the service of the Company. The Chief Executive Officer is free to set his own working hours, which shall be in keeping with his responsibilities and come to at least 40 hours per week.

2. The assumption of offices in supervisory bodies of other enterprises or of honorary positions in organizations requires prior written approval by the Company.

§ 8

Business and Trade Secrets

The Chief Executive Officer is obligated to maintain full confidentiality toward third parties with regard to all business and trade secrets, and to do so beyond the end of the contractual relationship. Any provision of confidential information to unauthorized third parties requires prior written approval by the Supervisory Board.

§ 9

Rights From Inventions and

Suggestions for Technical Improvements

1. The Chief Executive Officer is obligated to provide prompt written notice to the Company of any invention made by him over the course of the employment relationship that has arisen from his activity for the company or that is substantially based on the experience or work of the company (§ 4 ArbNErfG (Employee Invention Act)).

2. The Company is entitled within a period of 4 (four) months following the notice to lay claim to the invention through a written statement provided to the Chief Executive Officer. The invention and all rights thereto both domestically and abroad pass to the Company upon receipt of the statement.

3. If the Company does not lay claim to the invention within 4 (four) months, the Chief Executive Officer is entitled to freely dispose of it.

4. A Chief Executive Officer who has made a free invention (§ 4 ArbNErfG) during the employment relationship must promptly inform the Company thereof in writing. Before the Chief Executive Officer exploits a free invention elsewhere during the term of the employment relationship, he must first offer the Company a nonexclusive right to use the invention under reasonable terms and conditions if the invention falls within the existing or agreed working field of the Company’s operations at the time of the offer.

The Company’s privilege expires if the Company fails to accept the free invention within 3 (three) months.

5. The Company holds exclusive rights to inventions or technical improvements which the Chief Executive Officer has made or devised during his activity for the Company or in connection with his activity for the Company or on the basis of work for the Company. The Chief Executive Officer assigns all such rights to the Company, and the Company hereby accepts said assignment.

Restraint of Competition

The Chief Executive Officer is prohibited for the duration of this Agreement from working, for his own account or that of another, and on an employee or independent contractor basis, for an enterprise that is similar to the Company or that is or could become a competitor of it. Likewise, for the duration of this Agreement the Chief Executive Officer is not permitted to found or acquire such an enterprise, to acquire a direct or indirect interest therein, or to provide support for such an enterprise. Ownership of shares in a listed company that amounts to less than 5% of all shares and does not entitle him to exercise influence over the bodies of the respective company shall not be deemed an interest within the meaning of the preceding provision.

§ 11

Contractual Penalty

1. For each instance of contravention of the restraint of competition within the meaning of §10 or of the secrecy obligation pursuant to § 8, the Chief Executive Officer shall pay a contractual penalty in an amount corresponding to the average monthly remuneration received over the 12 months preceding his departure pursuant to § 3, Paragraph 1 of this Agreement.

2. In the event of an ongoing breach, the contractual penalty pursuant to § 1 is imposed anew for each month or part of a month.

3. Other claims by the Company arising from contravention of the restraint of competition or of the secrecy obligation are unaffected by the preceding provisions.

4. In each case of termination, the Company may, at its own discretion, and independently of the effectiveness of the termination and with reservation of its other rights, release the Chief Executive Officer from his activity for the Company or entrust him with other responsibilities that may be regarded as appropriate with respect to the professional qualifications of the Chief Executive Officer.

§ 13
