(b)If the Indemnitor has acknowledged in writing to the Indemnitee the Indemnitor’s responsibility for defending such Claim and such Claim is not a class action or criminal matter, the Indemnitor shall have the right to defend, at its sole cost and expense (with counsel reasonably selected by the Indemnitor and approved by the Indemnitee, such approval not to be unreasonably withheld or delayed), such Claim by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnitor to a final conclusion or settled at the discretion of the Indemnitor; provided, however, that the Indemnitor may not enter into any compromise or settlement unless (i) such compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnitee of a release from all liability in respect of such Claim; and (ii) the Indemnitee consents to such compromise or settlement, which consent shall not be unreasonably withheld or delayed unless such compromise or settlement involves (A) any admission of legal wrongdoing by the Indemnitee, (B) any payment by the Indemnitee that is not indemnified hereunder or (C) the imposition of any equitable relief against the Indemnitee, in which case ((A) – (C)) the Indemnitee may withhold its consent in its sole discretion. If Indemnitee determines in good faith that the defense is not being or ceases to be conducted diligently and in good faith, the Indemnitee shall have the right, at the expense of the Indemnitor, upon at least ten (10) Business Days’ prior written notice to the Indemnitor of its intent to do so, to undertake the defense of such Claim for the account of the Indemnitor (with counsel reasonably selected by the Indemnitee and approved by the Indemnitor, such approval not to be unreasonably withheld

or delayed). If the Indemnitee is defending such Claim, the Indemnitee shall keep the Indemnitor apprised of all material developments with respect to such Claim and promptly provide the Indemnitor with copies of all correspondence and documents exchanged by the Indemnitee and the opposing party(ies) to such litigation. If the Indemnitor has elected to defend such Claim or if the Indemnitor has otherwise acknowledged in writing its responsibility for indemnifying a Claim, the Indemnitee may not compromise or settle such litigation without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld or delayed.

(c)The Indemnitee may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnitor pursuant to this Section 8.2 and shall bear its own costs and expenses with respect to such participation; provided, however, that the Indemnitor shall bear such costs and expenses if counsel for the Indemnitor shall have reasonably determined that such counsel may not properly represent both the Indemnitor and the Indemnitee.

8.3     Exclusivity. From and after the Closing, other than in the event of fraud by a Party to this Agreement on the basis of the representations and warranties contained in this Agreement, this Article VIII will provide the exclusive remedy against either Party hereto for any breach of any representation, warranty, covenant or other claim arising out of or relating to this Agreement and/or the transactions contemplated herein, except nothing in this Agreement will prevent or otherwise limit either Party from seeking or obtaining injunctive or other equitable relief for any breach of any covenant or agreement set forth herein. The Parties hereto agree that the provisions in this Agreement relating to indemnification, and the limits imposed on Buyer’s remedies with respect to this Agreement and the transactions contemplated herein, were specifically bargained for between sophisticated parties and were specifically taken into account in the determination of the amounts to be paid to Seller hereunder.

8.4     Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement, the maximum aggregate amount of indemnifiable Damages that may be recovered from (a) Seller pursuant to Section 8.1(a) shall equal the Purchase Price, and (b) Buyer pursuant to Section 8.1(b) shall equal the Purchase Price.

8.5     Tax Treatment of Indemnity Payments. Any payments made to any Party pursuant to this Article VIII shall constitute an adjustment of the Purchase Price for Tax purposes and shall be treated as such by the Parties on their Tax Returns to the extent permitted by Legal Requirements.

10.1     Further Assurances.

(a)The Parties shall cooperate reasonably with each other in connection with any steps required to be taken as part of their respective obligations under this Agreement, including without limitation any notifications or filings required to be made to the FDA in connection with the transfer of the Purchased Assets, and shall (i) furnish upon request to each other such further information, (ii) execute and deliver to each other such other documents, and (iii) do such other acts and things, all as the other Party may reasonably request for the purpose of carrying out the intent of this Agreement and the transactions contemplated by this Agreement, including the use by Buyer, its Affiliates or their respective successors and assigns of the Priority Review Voucher in accordance with its terms and applicable Legal Requirements.

(b)Without limiting the foregoing, Buyer and Seller agree to cooperate and assist each other with respect to all filings or notifications to any Governmental Entity related to the transfer and assignment of the Purchased Assets.

In the absence of a protective order or other remedy, the Party subject to the requirement to disclose may disclose that portion (and only that portion) of the Confidential Information that, based upon advice of its counsel, it is legally compelled to disclose or that has been requested by such Governmental Entity; provided, however, that such Party shall use reasonable efforts to obtain reliable assurance that confidential treatment will be accorded by any Person to whom any Confidential Information is so disclosed.

Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party hereto shall be deemed cumulative with and not exclusive of any other remedy conferred hereby or by law or equity upon such Party, and the exercise by a Party hereto of any one remedy shall not preclude the exercise of any other remedy and nothing in this Agreement shall be deemed a waiver by any Party of any right to specific performance or injunctive relief.
