(b) the conduct of the Business of the Seller prior to the Closing;

(d) the failure of Seller to comply with any legal requirements with respect to bulk transfers, or acts of similar nature, except that this clause shall not affect the obligation of Buyer to pay and discharge the Assumed Liabilities, or

8.4 Claims for Indemnification.

(a) Claims. A person entitled to indemnification under this Section 8 (an “Indemnified Party”) shall give prompt written notification of any claim for Damages that may be subject to Section 8.2 or Section 8.3, as appropriate, to the person from whom indemnification is sought (the “Indemnifying Party”); provided, however, that the failure to give such notice shall not relieve, waive or diminish the Indemnifying Party’s obligations unless, and then only to the extent, such failure has resulted in the loss of material substantive rights with respect to the Indemnifying Party’s ability to defend such claim. An Indemnified Party wishing to assert a claim for indemnification which is not a third-party claim shall deliver to the Indemnifying Party a written notice which contains (i) a description and the amount of any Damages incurred by the

Indemnified Party, (ii) a demand for payment in the amount of such Damages if then known and determinable, and (iii) reasonable evidence to show that the claimed Damages are subject to the indemnification provision of Section 8. The Indemnifying Party shall have a reasonable period of time, not to exceed thirty (30) days, to investigate the claim for Damages and the Indemnified Party shall cooperate fully with the Indemnifying Party in such investigation.

(b) Third-Party Claims. An Indemnified Party shall give prompt written notice to the Indemnifying Party of the threat or commencement of any action, suit or proceeding relating to a third-party claim for which indemnification may be sought; provided, however, that the failure to give such notice shall not relieve, waive or diminish the Indemnifying Party’s obligations unless, and then only to the extent, such failure has resulted in the loss of material substantive rights with respect to the Indemnifying Party’s ability to defend such claim. Within thirty (30) days after delivery of such notification (or, if earlier, at least ten (10) days prior to the date that an answer to the applicable claim is due to be filed), the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense (in which event the fees and expenses of counsel to the Indemnified Party in connection therewith shall be considered Damages for purposes of this Agreement). The Party not controlling such defense may participate therein at its own expense; provided that if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the fees and expenses of counsel to the Indemnified Party solely in connection therewith shall be considered Damages for purposes of this Agreement; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one counsel for all Indemnified Parties. The party controlling such defense shall keep the other party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim that does not include a complete release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party or impairs or interferes with any asset, right or entitlement of the Indemnified Party, in each case, without the prior written consent of the Indemnified Party. In any event, the party who is required to consent to settlement shall not unreasonably withhold same.

8.5 Limitations on Indemnification. Notwithstanding anything to the contrary contained in this Agreement:

(a) neither the Buyer, on the one hand, nor the Seller, on the other hand, shall be liable with respect to claims for indemnification under this Section 8 unless and until the aggregate amount of all Damages with respect to such claims exceeds […***…]; provided, however, that once such minimum threshold has been met, subject to the limitation on maximum aggregate liability set forth in Section 8.5(c), an indemnifying party or parties shall be liable for such Damages from the first dollar of Damages;

***Confidential Treatment Requested

(b) claims for indemnification by the Buyer against the Seller shall be paid in compliance with the terms of this Agreement;

(c) the aggregate liability of the Seller on the one hand, or the Buyer on the other, for all Damages under this Section 8 shall not exceed an amount, in the aggregate, equal to the sum of the Purchase Price plus the amount of Contingent Payments actually paid pursuant to this Agreement;

(d) except in the case of third-party claims (where Damages shall include special, indirect, incidental, consequential or punitive damages to the extent they are due and payable by a party who is entitled to indemnification hereunder), Damages shall not include any special, indirect, incidental, consequential or punitive damages.

(e) The limitation on the indemnification obligations of the Seller that is set forth in Sections 8.5(a) and 8.5(c) shall not apply to any breach arising directly or indirectly from any circumstance of which the Seller had knowledge on or prior to the Closing Date.

8.6 Payment of Indemnification.

(a) Claims for indemnification under this Section 8.4(a) shall be paid by Indemnifying Party within thirty (30) days of notice thereof.

(b) Claims for indemnification under this Section 8.4(b) shall be paid by the Indemnifying Party within thirty (30) days of the notice thereof.

(i) In addition to any rights of setoff or other rights that an Indemnified Party may have at common law or otherwise, at any time after the first anniversary of the Closing Date, the Indemnified Party shall send written notice of a claim pursuant to Section 8.4. Subject to the determination of the arbitrator pursuant to Section 8.6(c)(ii), the Indemnified Party shall have the right to withhold and deduct any sum that is subject to indemnification claims, including any claims pursuant to Section 7.2 of this Agreement, from any amount otherwise payable by the Buyer to the Seller under this Agreement. The withholding and deduction of any such sum shall operate for all purposes as a complete discharge (to the extent of such sum) of the obligation to pay the amount from which such sum was withheld and deducted.

(ii) An Indemnified Party may submit a Claim for indemnification as permitted under Section 8.6(c)(i) of this Agreement as follows:

(A) The Indemnified Party invoking Expedited Arbitration under this Section 8.6(c)(ii) shall so notify the Indemnifying Party in writing. The notice shall contain a list of all Claims the Indemnified Party proposes to submit to Expedited Arbitration. Within twenty (20) days after receipt of any such notice, the Indemnifying Party receiving the notice shall promptly notify the Indemnified Party of any disputed issues that the

Indemnifying Party intends to include in the Expedited Arbitration. The disputed issues listed in the notice and in such reply will be the only issues submitted to Expedited Arbitration.

(B) If the Parties are not able to agree on an arbitrator within five (5) business days after notice of Expedited Arbitration has been received by Indemnifying Party, then either or both Parties may immediately request AAA to select an arbitrator; provided that in any event the arbitrator shall have not less than fifteen (15) years of biotechnology or life sciences services experience, unless otherwise agreed to by the Parties.

(C) Within fifteen (15) days after the designation of the arbitrator, the Parties shall each simultaneously submit to the arbitrator and one another in writing a proposal that contains that Party’s “final best offer” as to all matters that are the subject of the Claim. If a Party fails to submit a proposal within such timeframe, then the proposal of the submitting Party shall prevail. Each Party shall have five (5) business days from receipt of the other Party’s submission to submit a written response to such summary and at a hearing to take place over a period not to exceed three (3) business days, and in any event which will commence no later than ten (10) days after submission of the written responses. Each Party shall have a reasonable period of time to be determined by the arbitrator (which period of time shall be sufficient for the arbitrator to fully understand the proposals and the relative merits thereof) to argue for its proposal before the arbitrator. To the extent permitted by the AAA’s Commercial Arbitration Rules the arbitrator shall have the right to meet with the Parties, either alone or together, as necessary to make a determination.

(D) The arbitrator shall, within ten (10) days after the later of (i) submission of the responses or (ii) the completion of the hearing, or such longer period as the Parties may agree, select the single proposal of a Party that, in the determination of the arbitrator, as a whole is the most consistent with the requirements of this Agreement and is the most fair and reasonable to the Parties in light of the totality of the circumstances and the terms of the matters in dispute. At any time prior to the determination, either Party may accept the other Party’s position on any unresolved issue. The Parties shall inform the arbitrator of such accepted position and in such event such position will be deemed part of the final agreement and no longer subject to arbitration. For clarity, the arbitrator can only select a proposal from one Party in its entirety, and cannot “blend” the proposals or modify any proposal.
