on the Effective Date and ending on July 7, 2008 (the “Initial Period”), assist CuraGen, at CuraGen’s expense, in procuring placements for the 5,000,000 TopoTarget Shares comprising part of the Purchase Price on terms and conditions (including price) agreed upon by CuraGen in its sole discretion, provided that CuraGen agrees it shall sell any TopoTarget Shares for which (i) TopoTarget’s financial advisors are able to procure one or more placees for at least [**] or more TopoTarget Shares and (ii) the price per share (net of any expenses paid by CuraGen) is greater than or equal to the average closing price of TopoTarget Shares on Nasdaq OMX Nordic Exchange Copenhagen over the [**] trading day period ending on the Effective Date. Notwithstanding the foregoing, should TopoTarget notify CuraGen that it intends to engage in any rights offering of more than [**] TopoTarget Shares: (x) TopoTarget shall use its commercially reasonable efforts to include all of the 5,000,000 TopoTarget Shares held by CuraGen in such offering up to the maximum amount deemed prudent by TopoTarget’s financial advisors, in which event CuraGen shall share in the reasonable and customary expenses of the offering in proportion to the total number of TopoTarget Shares sold by CuraGen and TopoTarget in such offering, (y) CuraGen shall refrain from selling or otherwise transferring any of its TopoTarget Shares during the Initial Period until the earliest to occur of the end of the Initial Period and the completion and/or abandonment of such rights offering and (z) CuraGen shall commit to sell in such rights offering any TopoTarget Shares it holds, provided that the price per share (net of any expenses paid by TopoTarget) is greater than or equal to the average closing price of TopoTarget Shares on Nasdaq OMX Nordic Exchange Copenhagen over the [**] trading day period ending on the Effective Date. Notwithstanding the foregoing, should TopoTarget notify CuraGen that it intends to engage in any public offering (other than a rights offering) or private placement of equity securities representing more than [**] TopoTarget Shares: (x) CuraGen shall refrain from selling or otherwise transferring any of its TopoTarget Shares during the Initial Period until the earliest to occur of the end of the Initial Period and the completion and/or abandonment of such public offering or private placement, (y) TopoTarget shall offer to use the net proceeds of such offering to repurchase at a price per share (net of any expenses paid by TopoTarget) equal to the average closing price of TopoTarget Shares on Nasdaq OMX Nordic Exchange Copenhagen over the [**] trading day period ending on the Effective Date, provided that the offering is completed at a price per share (net of any expenses paid by TopoTarget) greater than or equal to the average closing price of TopoTarget Shares on Nasdaq OMX Nordic Exchange Copenhagen over the [**] trading day period ending on the Effective Date, and (z) CuraGen shall commit to sell to TopoTarget at such price any TopoTarget Shares it holds. In the event any such TopoTarget Shares have not been placed or otherwise sold in accordance with the first three (3) sentences of this Section 3.4(b) during the Initial Period, CuraGen shall be free to trade such TopoTarget Shares, provided such trades are in compliance in all cases with the requirements of the Securities Act and other applicable laws. In furtherance of the foregoing, TopoTarget shall take all steps necessary to ensure that the TopoTarget Shares delivered as part of the Purchase Price shall be freely tradeable under Danish law (but not the Securities Act) on Nasdaq OMX Nordic Exchange Copenhagen as soon as practicable but in no event later than thirty (30) days after the Effective Date. In the event any such TopoTarget Shares have not been placed or otherwise sold in accordance with the first two sentences of this Section 3.4(b) during the Initial Period and are not then freely tradeable under Danish law (but not the Securities Act) on Nasdaq OMX Nordic Exchange Copenhagen as July 8, 2008 (and CuraGen has not withheld any reasonable assistance requested by TopoTarget in connection with such freely tradeable obligation), TopoTarget shall pay to CuraGen on a

monthly basis in arrears an amount equal to (i) the number of such unplaced and unsold TopoTarget Shares multiplied by (ii) [**]% of the average closing price of TopoTarget Shares on Nasdaq OMX Nordic Exchange Copenhagen over the [**] trading day period ending on the Effective Date multiplied by (iii) the number of days elapsed since the later of (a) July 8, 2008 and (b) the last payment made pursuant to this sentence of this Section 3.4(b). With respect solely to the question of whether the TopoTarget Shares are freely tradeable prior to the expiration of the Initial Period (and not including any other default relating to the issuance of the TopoTarget Shares), such payment shall be TopoTarget’s sole liability and CuraGen’s sole remedy. CuraGen acknowledges that the TopoTarget Shares have not been registered under the Securities Act, and therefore all transactions in such TopoTarget Shares shall be conducted in transactions exempt from, or not subject to the registration requirements of, the Securities Act.

(c) For Net Sales of Products by TopoTarget and its Affiliates (but not for Net Sales by any Sublicensee), TopoTarget shall pay to CuraGen a royalty equal to [**] percent ([**]%) of the total Net Sales of Products received by TopoTarget or any Affiliate until such time as the amounts paid to CuraGen under this Section 3.4(c) and Section 3.4(d) below equal Six Million Dollars ($6,000,000) in the aggregate.

(d) With respect to any Sublicense to any Sublicensee, TopoTarget shall pay to CuraGen an amount equal to [**] percent ([**]%) of the Sublicense Income actually received in cash by TopoTarget until such time as the amounts paid to CuraGen under Section 3.4(c) above and this Section 3.4(d) equal Six Million United States Dollars ($6,000,000) in the aggregate.

(e) Notwithstanding anything to the contrary contained herein, only one royalty or other payment shall be paid to CuraGen for each unit of Product sold regardless of how many transactions may occur between manufacture of the unit of Product and purchase by the final end user, it being understood and agreed that (i) any royalty under Section 3.4(c) will be based upon the first arms length transaction between TopoTarget (or any Affiliate) and any Third Party, (ii) any payment under Section 3.4(d) shall only arise at the time of receipt in cash by TopoTarget of Sublicense Income and (iii) for the avoidance of doubt, sale of any specific unit of Product may only be eligible for a potential payment under either Section 3.4(c) or Section 3.4(d) but not both such Sections.

Section 3.5 Allocation of Purchase Price.

(a) CuraGen and TopoTarget agree that the Purchase Price and related consideration and reimbursement of expenses provided herein shall be allocated among the Transferred Assets on the basis of an allocation attached hereto as Schedule 3.5 (the “Allocation”). Each of CuraGen and TopoTarget agree to report, as and when required, the allocation of the Purchase Price, as adjusted, in a manner entirely consistent with the Allocation in the preparation and filing of all Tax Returns. None of the CuraGen or TopoTarget will take any action that would call into question the bona fides of the Allocation. Each of TopoTarget and CuraGen, on behalf of itself and its respective Affiliates, agrees that it will not take any position on a Tax Return that is inconsistent with the Allocation. Any subsequent adjustment to the Purchase Price shall be reflected in an allocation statement as revised by the Parties hereunder in a manner consistent with the allocation statement as originally prepared, except as

otherwise required by applicable Legal Requirement. CuraGen and TopoTarget shall jointly allocate the purchase price among the Transferred Assets and Licensed Rights and the termination of the License and Collaboration Agreement in a manner that is mutually acceptable and in accordance with applicable Tax and accounting rules.

The Indemnifying Party shall have the right, exercisable by written notice to the Indemnified Party within thirty (30) days (unless a shorter period is required by the circumstances) of receipt of notice from the Indemnified Party of the commencement of or

assertion of any claim or action, suit or proceeding by a Third Party in respect of which indemnity may be sought hereunder (a “Third Party Claim”), to assume and control the defense of such Third Party Claim which involves (and continues to involve) solely monetary damages; provided, that the Indemnifying Party expressly agrees in such notice that, as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy and discharge the Third Party Claim (all of the foregoing, the “Litigation Conditions”). For the purpose of the foregoing, the Indemnified Party shall promptly provide the Indemnifying Party with all supporting evidence of the Third Party Claim available to the Indemnified Party as well as any arguments identified by the Indemnified Party to oppose such Third Party Claim and comply with all reasonable requests for information from the Indemnifying Party so as to allow the Indemnifying Party to make to the extent possible an informed judgment as to its potential liability under this Article XII.

(b) In the event the Indemnifying Party assumes the defense in respect of any Third Party Claim (subject to the Litigation Condition), the Indemnifying Party shall conduct the defense of each Third Party Claim diligently and in good faith using all reasonable means and defenses available to it (and the Indemnified Party shall relinquish the conduct of the defense of the Third Party Claim). The Indemnified Party shall have the right, if it so notifies the Indemnifying Party, to be consulted in such defense of the Third Party Claim and to participate at its own expense and with counsel of its choice. In such event, the Indemnifying Party shall afford the Indemnified Party and its counsel the opportunity to comment and the right to object (which comments shall be taken into account to the extent reasonable and such right to object shall not be unreasonably exercised) with respect to the conduct of the defense of such Third Party Claim.

(c) In the event the Indemnifying Party does not assume the defense in respect of the Third Party Claim, the Indemnified Party shall conduct the defense of each Third Party Claim diligently and in good faith using all reasonable means and defenses available to it, and the Indemnifying Party shall promptly reimburse the Indemnified Party for its reasonable attorneys’ fees. The Indemnifying Party shall have the right, if it so notifies the Indemnified Party, to be consulted in such defense of the Third Party Claim and to participate at its own expense and with counsel of its choice. In such event, the Indemnified Party shall afford the Indemnifying Party and its counsel the opportunity to comment with respect to the conduct of the defense of such Third Party Claim.

(d) The Party conducting the defense of the Third Party Claim shall keep the other Party fully informed of the progress of any Third Party Claim and its defense, and shall with reasonable promptness provide such Party with copies all material notices, written communications and filings (including court papers) made by or on behalf of any of the parties to the underlying claim.

(e) From and after the delivery of a notice of a Third Party Claim under Section 12.4(a), at the reasonable request of the Indemnifying Party, the Indemnified Party shall grant the Indemnifying Party and its representatives all reasonable access to the books, records and properties of the Indemnified Party to the extent reasonably related to the matters to which the Third Party Claim relates. The Indemnifying Party will not, and shall require that its representatives do not, use (except in connection with such Third Party Claim) or disclose to any

Third Party other than the Indemnifying Party’s representatives (except as may be required by applicable Legal Requirements and legal process) any information obtained pursuant to this Section which is designated confidential by the Indemnified Party. All such access shall be granted during normal business hours and shall be granted under conditions which will not interfere with the business and operations of the Indemnified Party.

(f) The Indemnifying Party, if it shall have assumed the defense of any Third Party Claim as provided in this Agreement, may consent to a settlement of, or the entry of any judgment arising from, any such Third Party Claim without the prior written consent of the Indemnified Party so long as such settlement or judgment does not commit the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent that such Third Party Claim involves equitable or other non-monetary relief and such settlement does not involve the payment by the Indemnifying Party of monies to the Indemnified Party or a Third Party.

(g) Whether or not the Indemnifying Party chooses to defend any claim involving a Third Party, all the parties hereto shall cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith.

(h) The Indemnified Party shall take all reasonable steps to avoid or mitigate any Losses in respect of which it might be entitled to indemnification (other than seeking recovery under insurance policies with Third Parties) which would reduce the Loss recoverable by the Indemnified Party from the Indemnifying Party under this Article XII.

(i) No claim of the Indemnified Party or any of its Affiliates under this Agreement or the Transaction Documents may be indemnified more than once in respect of the same Loss suffered.

EXECUTION COPY

TRANSITION SERVICES AGREEMENT

This Transition Services Agreement (this “Agreement”) is entered into as of April 21, 2008 by and between TopoTarget A/S, a company duly organized and existing under the laws of Denmark and having offices at Symbion Science Park, Xxxxxxxxxxxx 0, 0000 Xxxxxxxxxx, Xxxxxxx (“TopoTarget”), and CuraGen Corporation, a company duly organized and existing under the laws of the State of Delaware and having offices at 000 Xxxx Xxxx Xxxxxx, Xxxxxxxx, Xxxxxxxxxxx 00000, XXX (“CuraGen”). As used herein, TopoTarget and CuraGen are referred to as the “Parties.”

W I T N E S S E T H :

WHEREAS, the Parties have entered into a Transfer and Termination Agreement (the “Transfer and Termination Agreement”) of even date herewith, pursuant to which, among other things, TopoTarget will acquire substantially all of CuraGen’s interests in HDAC Inhibitors and in certain other related rights and assets, all on the terms and conditions set forth in the Transfer and Termination Agreement;

WHEREAS, capitalized terms used in this Agreement but not defined herein shall have the meanings given to them in the Transfer and Termination Agreement and the rules of construction set forth in the Transfer and Termination Agreement shall apply to this Agreement; and

WHEREAS, pursuant to the terms of the Transfer and Termination Agreement, CuraGen has agreed to provide to TopoTarget certain transition services.

NOW, THEREFORE, in consideration of the mutual covenants and agreements of the parties contained herein, the parties agree as follows:

1. Services Provided.

1.1 Commencing on the Effective Date, subject to the terms hereof, CuraGen shall provide to TopoTarget those services set forth on Exhibit A with respect to the HDAC Inhibitor development program (the “Services”) and allocating resources as set forth in Section 1.2 below, until such Services are terminated in accordance with the terms hereof.

1.2 CuraGen shall allocate the following resources to performance of Services hereunder: (a) for the period beginning on the Effective Date and ending May 31, 2008, [**] FTEs; (b) for the period beginning on June 1, 2008 and ending June 30, 2008, [**] FTEs; and (c) for the period beginning July 1, 2008 and ending on the Termination Date, [**] of an FTE. For purposes of this Agreement, an “FTE” shall mean the full-time equivalent of one person performing scientific, technical, project management and/or managerial work for the specified period.

1.3 The Services shall be consistent with CuraGen’s standard processes, shall not include any Services that would be unlawful for CuraGen to provide, and shall not include the making of strategic business decisions for or general management of TopoTarget.

1.4 On the Effective Date, CuraGen and TopoTarget will each designate an appropriate point of contact for all questions and issues relating to the Services during the term of this Agreement (“Transition Managers”). The Transition Managers may meet from time to time at CuraGen’s facilities to discuss issues relating to the Services.

1.5 TopoTarget shall assume performance of all activities with respect to the HDAC Inhibitor development program other than the Services as of the Effective Date, and shall further assume performance of the Services on or prior to the Termination Date (as defined below). CuraGen shall have no obligation to perform any services other than the Services after the Effective Date, and shall have no obligation to perform the Services after the Termination Date. In furtherance of the foregoing, TopoTarget shall use reasonable efforts to make or obtain any approvals, permits and licenses and implement any systems as may be necessary for it to provide the Services independently as soon as reasonably practicable following the Effective Date, but in no event later than the Termination Date.

1.6 Without limiting Section 1.5 above, all activities related to the HDAC Inhibitor development program (including but not limited to communications, clinical, regulatory, drug safety, chemistry, manufacturing and controls, QA, project management, pharmacokinetics, financial management, and intellectual property) being performed by CuraGen immediately prior the Effective Date will be transferred from CuraGen to TopoTarget, after discussion and agreement by the Transition Managers, according to the following schedule:

1.6.1 [**]% of such program activity shall be transferred on or before five (5) business days after the Effective Date;

1.6.2 [**]% of such program activity shall be transferred on or before May 31, 2008; and

1.6.3 [**]% of such program activity shall be transferred on or before June 30, 2008.

1.7 TopoTarget shall provide CuraGen with such information and documentation in TopoTarget’s possession or control, and provide any other assistance, as is reasonably necessary for CuraGen to perform the Services.

1.8 CuraGen shall operate and maintain until May 21, 2008, in the same manner as operated and maintained as of the Effective Date, all software and databases used by CuraGen as of the Effective Date (including without limitation the Oracle software) to collect, store and manage any and all data generated by or on behalf

of CuraGen with respect to HDAC Inhibitors, including without limitation all data resulting from clinical trials relating thereto. CuraGen shall provide TopoTarget with reasonable access to such software and databases (including remote access), upon TopoTarget’s request.

1.9 CuraGen hereby agrees to submit to the FDA and the Canadian Bureau of Pharmaceutical Sciences, as applicable, letters attached hereto as Exhibits B1, B2 and B3 requesting transfer and assignment of the authorizations and files referenced therein from CuraGen to TopoTarget, and TopoTarget hereby agrees to submit to the FDA and the Canadian Bureau of Pharmaceutical Sciences, as applicable, the letters attached hereto as Exhibits C1, C2 and C3 accepting such transfers and assignments, in all cases within five (5) Business Days following the Effective Date. CuraGen and TopoTarget shall cooperate regarding the transfer and assignment from CuraGen to TopoTarget of all investigational new drug applications and other comparable permits and authorizations with regulatory authorities outside the United States relating to the HDAC Inhibitor development program as soon as reasonably practicable. In addition, CuraGen agrees to use its commercially reasonable efforts to assist TopoTarget in the transfer and continuation of the clinical development program related to the Product with minimal interruption to ongoing clinical trials in progress as of the Effective Date.

1.10 Subject to the terms and conditions of this Agreement, all Services provided hereunder will be terminated on or before the Termination Date. CuraGen shall be under no obligation to provide any Services to TopoTarget after the Termination Date, except to the extent agreed in writing by CuraGen and TopoTarget pursuant to Section 7 below.

1.11 CuraGen hereby agrees to file with the FDA, within five (5) Business Days following the Effective Date, the Request for Special Protocol Assessment letter, a form of which is attached hereto as Exhibit D, in such form and with such changes as TopoTarget shall reasonably request.

2. Performance Standard.

2.1 In performing the Services, CuraGen shall use reasonable efforts to provide, or ensure that any applicable Third Party will provide, a similar level of service and use the same degree of care and skill as it exercises in providing similar services for itself from the Effective Date until the Termination Date. All Services shall be performed in substantial compliance with applicable law. The foregoing is subject to Section 2.2 below.

2.2 CuraGen has disclosed to TopoTarget and TopoTarget hereby acknowledges that CuraGen has outsourcing relationships with Third Parties (“Service Providers”) who may, subject to Section 17 and in accordance with Section 1.1 hereof, in furtherance of CuraGen’s obligations under this Agreement, be delivering Services to TopoTarget. To the extent required under any such Service Provider

agreements governing such Services, or otherwise as requested by CuraGen in its reasonable discretion and subject to Section 17 hereof, TopoTarget agrees to cooperate with CuraGen and will assist CuraGen in obtaining Third Party consents, licenses, sublicenses, or approvals necessary to permit CuraGen or the applicable Service Provider to perform or otherwise make the Services available to TopoTarget. Without limitation to the foregoing, CuraGen shall make available to TopoTarget as part of the Services those services CuraGen receives pursuant to the Clinical Trial Agreement by and between CuraGen and the Division of Cancer Treatment and Diagnosis of the National Cancer Institute (NCI) dated as of August 1, 2004 (“NCI Agreement”). During the term hereof the Parties shall cooperate to obtain for TopoTarget an arrangement whereby TopoTarget may continue to receive the benefits of the NCI Agreement after the Termination Date, either via assignment of the NCI Agreement to TopoTarget or otherwise.

2.3 EXCEPT AS PROVIDED IN THIS AGREEMENT, NEITHER PARTY MAKES ANY WARRANTIES OR REPRESENTATIONS OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO ANY SERVICES PROVIDED HEREUNDER.

3. Fees.

3.1 TopoTarget shall pay to CuraGen as consideration for the Services an amount equal to (a) the FTE Rate multiplied by (b) the number of FTEs (or fraction thereof) allocated to the performance of Services in accordance with Section 2.2 for the applicable period multiplied by (c) a fraction, the numerator of which is the number of days in the applicable period and the denominator of which is 365. For purposes of this Agreement, the FTE Rate shall mean [**] Dollars ($[**]).

3.2 CuraGen shall invoice TopoTarget for the Services provided hereunder in arrears on a monthly basis. TopoTarget shall pay any invoice for Services promptly but in no event later than thirty (30) days after the date of invoice. Late payments due hereunder shall bear interest at the prime rate then in effect, plus five percent (5%) per annum or the maximum amount allowed by law, whichever is less.

4. Confidentiality. The Parties agree that information disclosed in connection with this Agreement shall be governed by the terms and conditions of Section 10.6 of the Transfer and Termination Agreement.

5. Ownership. This Agreement and the performance of the Services hereunder will not affect the ownership of any of the Transferred Assets or Excluded Assets allocated in the Transfer and Termination Agreement. All Inventions and Know-How that are conceived and/or reduced to practice by or on behalf of CuraGen or its Affiliates, whether alone or with others, that (i) result from its performance of the Services, including the conduct of the HDAC Inhibitor program, or (ii) relate to the Transferred Assets disclosed to or

accessed by CuraGen in connection with this Agreement, whether during or after the Term, and all Patents and other intellectual property rights relating thereto (collectively, the “TopoTarget Property”), shall be disclosed promptly to TopoTarget and shall be considered a “work made for hire” (as that term is defined under Section 101 of the U.S. Copyright Act, 17 U.S.C. § 101) with TopoTarget being the person for whom the work was prepared and the TopoTarget Property shall be the sole and exclusive property of TopoTarget. In the event that any TopoTarget Property is deemed not to be a “work made for hire”, CuraGen agrees to assign, and hereby does assign, unconditionally and irrevocably to TopoTarget, all of CuraGen’s right, title and interest in and to the TopoTarget Property. No compensation or other payments in addition to the charges for the Services payable pursuant to Section 3 shall be payable in respect of the ownership by, or assignment to, TopoTarget of TopoTarget Property. CuraGen has entered into a binding agreement with each of its employees and agents assigning to CuraGen any and all rights of such employees and agents in any intellectual property conceived of or reduced to practice by such employees and agents. Without limiting the foregoing, neither party will gain, by virtue of this Agreement or the Services hereunder, by implication or otherwise, any rights of ownership of any property or intellectual property rights owned by the other.

6. Limitation of Liabilities.

6.1 Disclaimer. IN NO EVENT SHALL EITHER PARTY OR CURAGEN’S SERVICE PROVIDERS BE LIABLE FOR ANY LOST PROFITS OR CONSEQUENTIAL, PUNITIVE, SPECIAL OR OTHER INDIRECT DAMAGES EXCEPT FOR THOSE CAUSED BY GROSS NEGLIGENCE, WILFUL MISCONDUCT OR ANY BREACH OF SECTION 4.

6.2 Limitation. IN NO EVENT SHALL CURAGEN’S OR ITS SERVICE PROVIDERS’ LIABILITY FOR ANY ACTION, REGARDLESS OF THE FORM OF ACTION, WHETHER IN TORT OR CONTRACT, ARISING UNDER THIS AGREEMENT EXCEED SEVENTY-FIVE PERCENT (75%) OF THE AMOUNT INVOICED TO TOPOTARGET BY CURAGEN FOR SERVICES HEREUNDER IN THE TWELVE (12) MONTH PERIOD IMMEDIATELY PRECEDING THE CIRCUMSTANCE THAT GAVE RISE TO SUCH LIABILITY EXCEPT FOR LIABILITIES CAUSED BY GROSS NEGLIGENCE, WILFUL MISCONDUCT OR ANY BREACH OF SECTION 4.

7. Term, Extension and Termination.

7.1 Term. This Agreement shall become effective on the Effective Date and, unless sooner terminated in accordance with the terms hereof, shall continue in effect until December 31, 2008 (the “Term”). The date of expiration of the Term, or of termination in accordance with Section 7.2 below, shall be the “Termination Date.”

7.2 Termination. This Agreement may be terminated earlier in accordance with any of the following provisions:

7.2.1 By mutual written consent of both CuraGen and TopoTarget;

7.2.2 By TopoTarget on thirty (30) days written notice to CuraGen;

7.2.3 By either party entitled to the benefit of the performance of any of the obligations under this Agreement (the “Non-Defaulting Party”), if the other party (the “Defaulting Party”) shall fail to perform or default in such performance. The Non-Defaulting Party must give written notice to the Defaulting Party specifying the nature of such failure or default and stating that the Non-Defaulting Party intends to terminate this Agreement with respect to the Defaulting Party if such failure or default is not cured within thirty (30) days after such written notice. If any failure or default so specified is not cured within such thirty (30) day period, the Non-Defaulting Party may elect to immediately terminate this Agreement with respect to the Defaulting Party; provided, however, that if the failure or default relates to a dispute contested in good faith by the Defaulting Party, the Non-Defaulting Party may not terminate this Agreement pending the resolution of such dispute. Such termination shall be effective upon provision of written notice of termination from the Non-Defaulting Party to the Defaulting Party and shall be without prejudice to any other remedy which may be available to the Non-Defaulting Party against the Defaulting Party.

7.3 Effect of Termination. TopoTarget specifically agrees and acknowledges that all obligations of CuraGen to provide Services hereunder shall immediately cease on the Termination Date, or such earlier date of termination pursuant to Section 7.2, and CuraGen’s obligations to provide all of the Services shall immediately cease upon the termination of this Agreement.

7.4 Survival. Notwithstanding the expiration or early termination of this Agreement or any Services hereunder, Sections 1.8, 2.3, 3, 4, 5, 5, 7, 8, 9, 11, 12, 13, 15, 16, 17, 18, 19 and 20 will survive the expiration or termination of this Agreement for any reason. The expiration or termination of this Agreement for any reason will not release either party from any liabilities or obligations set forth herein which (a) the parties have expressly agreed will survive any such expiration or termination or (b) remain to be performed or by their nature would be intended to be applicable following any such expiration or termination.

8. Independent Contractors. The parties hereto understand and agree that this Agreement does not make either of them an agent or legal representative of the other for any purpose whatsoever. Neither party is granted, by this Agreement or otherwise, any right or authority to assume or create any obligation or responsibilities, express or implied, on behalf of or in the name of the other party, or to bind the other party in any manner

whatsoever. The parties expressly acknowledge that (a) CuraGen is an independent contractor with respect to TopoTarget in all respects, including the provision of the Services, and (b) that the parties are not partners, joint venturers, employees or agents of or with each other.

9. Beneficiary of Services; No Third Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto, and nothing expressed or implied shall give or be construed to give any person any legal or equitable rights hereunder, whether as a Third Party beneficiary or otherwise. CuraGen and TopoTarget agree, and TopoTarget represents and warrants, that the Services will be provided solely to, and will be used solely by, TopoTarget, in each case only in connection with the Contributed Assets and the Assumed Liabilities. TopoTarget shall not resell or provide the Services to any other Person, or permit the use of the Services by any Person other than TopoTarget.

10. Force Majeure. Neither party will be held liable to the other for any delay or failure of performance where such delay or failure results from events beyond that party’s control, including acts of God, earthquakes, fires, floods, civil disturbance, strikes, labor disputes, and lawful governmental action.

11. Entire Agreement. This Agreement and the Transfer and Termination Agreement constitute the entire agreement of the parties with respect to the subject matter hereof, and supersede all prior agreements, understandings and negotiations, both written and oral, between the parties with respect to the subject matter hereof.

12. Amendment; Waiver. This Agreement may be amended, and any provision of this Agreement may be waived, if but only if such amendment or waiver is in writing and signed, in the case of an amendment, by CuraGen and TopoTarget, or in the case of a waiver, by the party against whom the waiver is effective. No failure or delay by any party in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

13. Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given (i) by personal delivery, (ii) upon transmission by facsimile machine if a confirmation sheet is emitted from such machine or (iii) upon delivery by an internationally recognized overnight courier service, each to the other Party at the following address (or at such other address as shall be given in writing by any Party to the other in accordance with this Section 13):

14. Non Assignability. Neither party may, directly or indirectly, in whole or in part, either by operation of law or otherwise, assign or transfer this Agreement without the other party’s prior written consent. Any attempted assignment, transfer or delegation without such prior written consent will be void.

15. Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument. Copies of executed counterparts transmitted by telecopy, telefax or other electronic transmission service shall be considered original executed counterparts for purposes hereof, provided that receipt of copies of such counterparts is confirmed. This Agreement shall become effective when each party has received a counterpart hereof signed by the other party hereto.

16. Severability. If any provision of this Agreement shall be declared by any court of competent jurisdiction to be illegal, void or unenforceable, all other provisions of this Agreement shall not be affected and shall remain in full force and effect, and CuraGen and TopoTarget shall negotiate in good faith to replace such illegal, void or unenforceable provision with a provision that corresponds as closely as possible to the intentions of the parties as expressed by such illegal, void, or unenforceable provision.

17. Subcontractors and Outsourcing. Except with respect to Third Parties that are counterparties to any Contracts included in the Transferred Assets, CuraGen shall not have the right to subcontract or outsource any of its obligations hereunder without the express written consent of TopoTarget.

18. Other Agreements. This Agreement is not intended to amend or modify, and should not be interpreted to amend or modify in any respect the rights and obligations of CuraGen and TopoTarget under the Transfer and Termination Agreement.

19. Taxes. The fees described in Section 3 are exclusive of value added taxes, sales taxes and any other similar taxes. TopoTarget will be responsible for all taxes (other than taxes based on net income or net profits) imposed by applicable taxing authorities on the provision of Services to TopoTarget hereunder. If CuraGen is required to pay such taxes, TopoTarget shall promptly reimburse CuraGen therefor.

20. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to its choice of law rules. With respect to any suit, action or proceeding arising out of or relating to this Agreement (each, a “Proceeding”), each Party hereto irrevocably (i) agrees and consents to submit to the non-exclusive jurisdiction of the United States District Court for the Southern District of New York, United States of America, and (ii) waives, and agrees not to assert by way of motion, defense, or otherwise, in any such Proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Proceeding is brought in an inconvenient forum, that the venue of the Proceeding is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above-named courts. Notwithstanding the immediately preceding sentence, either Party may seek injunctive or similar equitable relief as to any matter arising out of or relating to this Agreement in any court of competent jurisdiction.

IN WITNESS WHEREOF, the parties hereto have executed this Transition Services Agreement as of the day and year first above written.
