AGREEMENT

          (b) Extracts. The extracts more fully described and listed on Schedule 1.1(b) (the “Extracts”);

For avoidance of doubt, notwithstanding anything to the contrary in this Agreement, the Purchased Assets do not, and shall not, include: (i) the chemical compound known as CTK000120 (cyclophilin inhibitor), its derivatives and analogs, any intellectual property, data, results or materials generated in connection with such compound, or rights for copies of the producing strain for such compound (identified as A04460); (ii) any Contracts other than the Transferred Contracts; (iii) any books, files, papers, correspondence, databases, documents, records and documentation not related to the Compounds, Extracts, Strains and AFP Technology, even if forming part of any books, files, correspondence, databases, documents, records or documentation constituting Books and Records; (iv) laboratory or other equipment; or (v) any other asset not expressly identified in Sections 1.1(a) through (i) as a Purchased Asset.

                    (B) Upon the first IND pertaining to CTK000147 (proteasome inhibitor) or a Structural Analog being approved or allowed by the FDA (whether such IND is filed or caused to be filed by Parent, Purchaser or any of their respective Affiliates), Purchaser shall deliver to Sellers an aggregate of $250,000, in cash, by wire transfer of immediately available funds; provided, that one-half of each such payment shall be delivered to each Seller.

          (b) All representations and warranties of Sellers set forth in this Agreement other than those contained in Sections 4.1, 4.3 and 4.4 will survive the Closing but will terminate and expire, and will cease to be of any force or effect, at 5:00 PM Eastern time on the date which is eighteen (18) months after the Closing Date and all liability of Sellers with respect to such representations and warranties will thereupon be extinguished; provided, however, that if, prior to such eighteen (18) month anniversary date, Purchaser shall have duly delivered to Sellers, in conformity with all of the applicable procedures set forth in Section 5.1(e), a Purchaser Claim Notice, then the specific claim set forth in such Purchaser Claim Notice will survive (and will not be extinguished upon) such eighteen (18) month anniversary;

          (c) Subject to the limitations set forth in this Section 6.1 and elsewhere in this Agreement, from and after the Closing Date, each Seller, severally, shall indemnify, defend and hold harmless Purchaser, Parent and their respective Affiliates (each a “Purchaser Indemnitee”) from and against one-half of any and all Damages, whether or not involving a third-party claim, including attorneys’ fees and related defense costs and expenses (collectively, “Purchaser Damages”), arising out of, relating to or resulting from: (i) any breach of a representation or warranty of Sellers contained in this Agreement; (ii) any breach or non-performance by Sellers of any of their covenants or agreements contained in this Agreement; (iii) the Cetek Agreements; or (iv) the enforcement of this Section 6.1.

          (d) Sellers will not be required to indemnify Purchaser Indemnitee with respect to any Purchaser Damages, except to the extent that the cumulative amount of the Purchaser Damages actually incurred by Purchaser Indemnitee exceeds $50,000; and Sellers will only be required to pay, and will only be liable for, the amount by which the cumulative amount of the Purchaser Damages actually incurred by Purchaser Indemnitee exceeds $25,000;

          (e) If any Purchaser Indemnitee wishes to assert an indemnification claim against Sellers, such Purchaser Indemnitee will deliver to Sellers, as soon as reasonably practicable, a written notice (a “Purchaser Claim Notice”) setting forth:

               (i) the provision of this Agreement upon which such indemnification claim is based;

               (ii) a reasonably detailed description of the facts and circumstances giving rise to the indemnification claim; and

               (iii) a reasonably detailed description of, and a good faith estimate of the total amount of, the Purchaser Damages actually incurred or expected to be incurred by Purchaser Indemnitee in connection with such indemnification claim.

Sellers will have the right, at their election and at their sole expense, to assume the defense of any such matter with their own counsel. If Sellers elects to assume the defense of any such matter, then:

               (i) Notwithstanding anything to the contrary contained in this Agreement, Sellers will not be required to pay or otherwise indemnify Purchaser Indemnitee against any attorneys’ fees or other expenses incurred on behalf of Purchaser Indemnitee in connection with such matter following Sellers’ election to assume the defense of such matter;

               (iv) Purchaser Indemnitee will otherwise fully cooperate as reasonably requested by Sellers in the defense of such matter;

          (g) If Sellers elect not to assume the defense of such matter, then Purchaser Indemnitee will proceed diligently to defend such matter with the assistance of counsel reasonably satisfactory to Sellers; provided, however, that Purchaser Indemnitee will not settle, adjust or compromise such matter, or admit any liability with respect to such matter, without the prior written consent of Sellers (which will not be unreasonably withheld).

          (h) To the extent Sellers make or are required to make any indemnification payment to Purchaser Indemnitee, Sellers will be entitled to exercise, and will be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that Purchaser Indemnitee may have against any other Person with respect to any Purchaser Damages, circumstances or matter to which such indemnification payment is directly or indirectly related. Purchaser Indemnitee will take such actions as Sellers may reasonably request for the purpose of enabling Sellers to perfect or exercise Sellers’ right of subrogation hereunder.

          (i) The right of Purchaser Indemnitee to assert indemnification claims and receive indemnification payments pursuant to this Section 6.1 will be the sole and exclusive right and remedy exercisable by Purchaser Indemnitee with respect to any claim arising under or related to this Agreement; provided, however, that this Section 6.1(i) shall not prevent Purchaser Indemnitee from asserting a tort claim for fraud against Sellers in appropriate circumstances.

          (c) Subject to the limitations set forth in this Section 6.2 and elsewhere in this Agreement, from and after the Closing Date, Purchaser and Parent shall jointly and severally indemnify, defend and hold harmless each Seller and his respective executors, administrators, heirs, permitted assigns, representatives and agents (each a “Seller Indemnitee”) from and against any and all Damages, whether or not involving a third-party claim, including attorneys’ fees and related defense costs and expenses (collectively, “Seller Damages”), arising out of, relating to or resulting from: (i) any breach of a representation or warranty of Parent or Purchaser contained in this Agreement; (ii) any breach or non-performance by Parent or Purchaser of any of their respective covenants or agreements contained in this Agreement; (iii) the Assumed Liabilities; (iv) the operation of the Purchased Assets after the Closing Date; (v) any Liabilities to On Assignment Staffing Services, Inc. d/b/a On Assignment Lab Support, or (vi) the enforcement of this Section 6.2.

          (d) If any Seller Indemnitee wishes to assert an indemnification claim against Purchaser or Parent, such Seller Indemnitee will deliver to Purchaser and Parent, as soon as reasonably practicable, a written notice (“Seller Claim Notice”) setting forth:

               (i) the provision of this Agreement upon which such indemnification claim is based;

               (ii) a reasonably detailed description of the facts and circumstances giving rise to the indemnification claim; and

Purchaser and Parent will have the right, at their election and at their sole expense, to assume the defense of any such matter with their own counsel. If Purchaser or Parent elects to assume the defense of any such matter, then:

               (i) Notwithstanding anything to the contrary contained in this Agreement, Purchaser and Parent will not be required to pay or otherwise indemnify Seller Indemnitee against any attorneys’ fees or other expenses incurred on behalf of Seller Indemnitee in connection with such matter following Purchaser’s or Parent’s election to assume the defense of such matter;

               (ii) Seller Indemnitee will make available to Purchaser and Parent all books, records and other documents and materials that are under the control of Seller Indemnitee or any of Seller Indemnitee’s Affiliates, advisors or representatives and that Purchaser or Parent reasonably considers necessary or desirable for the defense of such matter;

               (iii) Seller Indemnitee will execute such documents and take such other actions as Purchaser or Parent may reasonably request for the purpose of facilitating the defense of, or any settlement, compromise or adjustment relating to, such matter;

               (iv) Seller Indemnitee will otherwise fully cooperate as reasonably requested by Purchaser or Parent in the defense of such matter;

               (v) Seller Indemnitee will not admit any liability with respect to such matter; and

               (vi) Purchaser and Parent will have the exclusive right to settle, adjust or compromise such matter, on such terms as Purchaser and Parent may consider appropriate, with the consent of Seller Indemnitee (which will not be unreasonably withheld).

          (f) If Purchaser or Parent elects not to assume the defense of such matter, then Seller Indemnitee will proceed diligently to defend such matter with the assistance of counsel reasonably satisfactory to Purchaser and Parent; provided, however, that Seller Indemnitee will not settle, adjust or compromise such matter, or admit any liability with respect to such matter, without the prior written consent of Purchaser and Parent (which will not be unreasonably withheld).

          (g) To the extent Purchaser and Parent makes or is required to make any indemnification payment to Seller Indemnitee, Purchaser and Parent will be entitled to exercise, and will be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that Seller Indemnitee may have against any other Person with respect to any Seller Damages, circumstances or matter to which such indemnification payment is directly or indirectly related.

     6.3 Mitigation. Upon any Purchaser Indemnitee or Seller Indemnitee (each an “Indemnitee”) becoming aware of any claim as to which indemnification may be sought by such Indemnitee pursuant to this Article 6, an Indemnitee shall utilize reasonable efforts, consistent with normal practices and policies and good commercial practice, to mitigate the Damages related to such claim.

     6.4 Calculation of Damages.

          (a) No Party hereto will be liable to another Party hereunder for any punitive, consequential, exemplary, incidental or special damages, or for lost profits, diminution in value (including based upon a multiple of earnings or revenue, whether adjusted or unadjusted, or any similar valuation metrics), business interruption, cost of capital or loss of business reputation or opportunity, in any case relating to any claim for which such Party may be entitled to indemnification under this Agreement.

          (b) The amount of any Damage for which indemnification is provided hereunder shall be net of any amounts recovered by the Indemnitee under insurance policies or other right to indemnification or contribution from any third Person with respect to such Damages (net of any deductibles). In the event that any claim for indemnification asserted hereunder is, or may be, the subject of any insurance coverage or other right to indemnification or contribution from any third Person, the Indemnitee expressly agrees to promptly notify the applicable insurance carrier of any such claim or loss and tender defense thereof to such carrier, and shall also promptly notify any potential third party indemnitor or contributor which may be liable for any portion of such losses or claims. The Indemnitee agrees to pursue such claims diligently and to reasonably cooperate with each applicable insurance carrier and third party indemnitor or contributor. The Indemnitee shall use its best efforts to seek recoveries under insurance policies. In the event that any insurance proceeds or any indemnity, contribution or other similar payment is recovered by the Indemnitee with respect to an indemnification obligation that the Sellers, Parent or Purchaser, as applicable, (each an “Indemnitor”) previously paid to the Indemnitee, the Indemnitee will pay such recovered amount back to the Indemnitor within ten (10) days after receipt thereof by wire transfer or delivery of other immediately funds to an account designated in writing by the Indemnitor.

          (c) The amount of any Damage for which indemnification is provided shall be reduced to take account of any Tax benefit realizable by the Indemnitee arising from the incurrence or payment of any such Damage. In computing the amount of any such Tax benefit, the Indemnitee shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified Damage.
