Except for the submission to the FDA of the FDA Notification Package referenced in Section 3.2(c) and the filing of a premerger notification and report form under the HSR Act, no filing, authorization, consent, approval, permit, order, registration or declaration, governmental or otherwise, is necessary to enable or authorize Seller to enter into, and to perform its obligations under, this Agreement.

(c) Notwithstanding the foregoing, nothing in this Agreement shall require, or be construed to require, the Parties or any of their respective Affiliates to offer or agree to (A) (i) sell, hold, hold separate, divest, license, discontinue or limit, before or after the Closing Date, any assets, businesses, equity holdings, intellectual property, or other interests or (ii) any conditions relating to, or changes or restrictions in, the operations of any such assets, businesses, equity holdings, intellectual property or interests (including but not limited to any requirements to enter into new contracts or modify or terminate existing contracts) or (B) any material modification or waiver of the terms and conditions of this Agreement.

8.2 No Solicitation. During the period from the Effective Date and continuing until the earlier of the termination of this Agreement or the Closing Date, Seller shall not, nor shall it authorize, instruct, or permit any of its Affiliates or any of their respective Representatives to, (i) solicit, initiate, or encourage the submission of, any proposal or indication of interest relating to an Alternative Transaction or any inquiry, proposal or offer that is reasonably likely to lead to an Alternative Transaction, (ii) participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquires or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Alternative Transaction, (iii) accept any proposal or offer from any Person in respect of an Alternative Transaction, or (iv) resolve to propose or agree to do any of the foregoing. Upon the execution of this Agreement, Seller and its Affiliates shall immediately cease and cause to be terminated any existing discussions with any Person that are in respect of an Alternative Transaction.

ARTICLE IX
INDEMNIFICATION

9.1 Indemnification.

(a) Indemnification by Seller. From and after the Closing, Seller will indemnify, defend and hold Buyer and its Affiliates, and their respective directors, officers, employees and agents harmless for, from and against any and all Damages to the extent arising out of or resulting from (i) any breach of Seller’s representations, warranties, covenants or obligations under this Agreement or any certificate delivered by Seller hereunder, (ii) Seller’s grossly negligent and/or wrongful acts, omissions or misrepresentations, regardless of the form of action, in connection with this Agreement, and/or (iii) any Excluded Liabilities.

(b) Indemnification by Buyer. From and after the Closing, Buyer will indemnify, defend and hold Seller and its Affiliates, and their respective directors, officers, employees and agents harmless for, from and against any and all Damages to the extent arising out of or resulting from (i) any breach of Buyer’s representations, warranties, covenants or obligations under this Agreement or any certificate delivered by Buyer hereunder, (ii) Buyer’s grossly negligent and/or wrongful acts, omissions or misrepresentations, regardless of the form of action, in connection with this Agreement, and/or (iii) Buyer’s, its Affiliates’, or any subsequent transferee’s use of the Transferred Rights after Closing.

9.2 Indemnification Procedures for Third Party Claims.

(a) A Person entitled to indemnification pursuant to Section 9.1 will hereinafter be referred to as an “Indemnitee.” A Party obligated to indemnify an Indemnitee hereunder will hereinafter be referred to as an “Indemnitor.” Indemnitee shall inform Indemnitor of any indemnifiable Damages arising out of a claim by a Third Party in respect of which an Indemnitee may seek indemnification pursuant to Section 8.1 (a “Third Party Claim”) as soon as reasonably practicable after the Third Party Claim arises, it being understood and agreed that the failure to give such notice will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that such Indemnitor is actually and materially prejudiced as a result of such failure to give notice.

(b) If the Indemnitor has acknowledged in writing to the Indemnitee within thirty (30) days of receipt of the Third Party Claim the Indemnitor’s responsibility for defending such Third Party Claim, the Indemnitor shall have the right to defend, at its sole cost and expense, such Third Party 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 Third Party Claim; and (ii) the Indemnitee consents to such compromise or settlement, which consent shall not be 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. If the Indemnitor does not elect to assume control of the defense of a Third Party Claim or if a good faith and diligent defense is not being or ceases to be materially conducted by the Indemnitor, 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 Third Party 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), provided, that the Indemnitee shall keep the Indemnitor apprised of all material developments with respect to such Third Party 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. 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 Third Party Claim controlled by the Indemnitor pursuant to this Section 9.2 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.

9.3 Direct Claims. A claim for indemnification for any matter not involving a Third Party Claim may be asserted by written notice to the Party from whom indemnification is sought. Such notice shall include the facts constituting the basis for such claim for indemnification, the Sections of this Agreement upon which such claim for indemnification is then based, and an estimate, if possible, of the amount of Damages suffered or reasonably expected to be suffered by the Indemnitee.

9.4 Buyer Knowledge. The right to indemnification pursuant to this Article IX shall not be affected by any investigation conducted or any knowledge acquired by Buyer, its Affiliates or Representatives at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to the accuracy or inaccuracy of, or compliance with, any representation, warranty, covenant, or obligation.

ARTICLE X
TERMINATION

10.1 Termination Prior to Closing. Notwithstanding any contrary provisions of this Agreement, the respective obligations of the Parties hereto to consummate the transactions contemplated by this Agreement may be terminated and abandoned at any time before the Closing only as follows:

(a) Upon the mutual written consent of Buyer and Seller; or

(b) By either Party, by written notice to the other Party if the Closing has not occurred on or before one hundred twenty (120) days from the Effective Date for any reason; provided, however, that the right to terminate this Agreement under this Section 10.1(b) shall not be available to any Party whose material breach of any provision set forth in this Agreement has resulted in the failure of the Closing to occur on or before such date.

10.2 Effect of Termination. In the event of the termination of this Agreement as provided in Section 10.1, written notice thereof shall forthwith be given to the other Party hereto specifying the provision hereof pursuant to which such termination is made, and this Agreement shall forthwith become null and void (except for the provisions of this Section 10.2, Section 11.4, ARTICLE I and ARTICLE XII, which shall survive any such termination) and there shall be no liability on the part of Buyer or Seller except for Damages resulting from any breach prior to termination of this Agreement by Buyer or Seller. If this Agreement is terminated, Buyer will promptly withdraw any Pre-Closing PRV Notice submitted to the FDA prior to the Closing.

ARTICLE XI
ADDITIONAL COVENANTS

11.1 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 any notifications or filings required to be made to the FDA in connection with the transfer of the Transferred Rights, 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 and/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 Transferred Rights.

11.2 Compliance with Legal Requirements. Seller shall, and shall cause its Affiliates and each of their respective successors in interest to the rare pediatric disease product for which the Priority Review Voucher was awarded to, at all times comply with all Legal Requirements applicable to the Transferred Rights, including any and all Legal Requirements applicable to the use or transfer of the Priority Review Voucher. Seller shall promptly forward to Buyer any communications or notices it or its Affiliates receive from any Governmental Entity to the extent relating to the Transferred Rights (and not otherwise with respect to the product approved in the NDA Approval Letter). Without limiting the generality of the foregoing, to the extent required, now or in the future, under applicable Legal Requirements or otherwise by the FDA for the use or transfer of the Priority Review Voucher, or to avoid revocation of the Priority Review Voucher, Seller shall, and shall cause its Affiliates and each of their respective successors in interest to the rare pediatric disease product for which the Priority Review Voucher was awarded, to submit a post-approval production report to the United States Secretary of Health and Human Services not later than five (5) years after the approval of such rare pediatric disease product in accordance with section 529(e)(2) of the FDC Act.

11.3 Marketing. Seller will market in the United States the rare pediatric disease product for which the Priority Review Voucher was awarded for the 365-day period beginning on the date of the FDA approval of such rare pediatric disease product to the extent required, now or in the future, under applicable Legal Requirements or otherwise by any applicable Governmental Entity for the use or transfer of the Priority Review Voucher.

11.4 Nondisclosure.

(a) With respect to Confidential Information received from a Party, the other Party will (i) not use such Confidential Information for any reason other than to carry out the intent and purpose of this Agreement, and (ii) not disclose such Confidential Information to any Person, except in each case as otherwise expressly permitted by this Agreement or with the prior written consent of the disclosing Party.

(b) A Party may disclose Confidential Information to its Affiliates and their respective Representatives on a need-to-know basis.

(c) A Party will (i) enforce the terms of this Section 11.4 as to its Representatives, (ii) take such action to the extent necessary to cause its Representatives to comply with the terms and conditions of

this Section 11.4, and (iii) be responsible and liable for any breach of this Section 11.4 by it or its Representatives.

(d) If a Party becomes compelled by a court or is requested by a Governmental Entity to make any disclosure that is prohibited or otherwise constrained by this Section 11.4, such Party shall provide the disclosing Party with prompt notice of such compulsion or request so that it may seek an appropriate protective order or other appropriate remedy or waive compliance with the provisions of this Section 11.4. 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.

11.5 Disclosures Concerning this Agreement. Buyer and Seller agree not to (and to ensure that their respective Affiliates do not) issue any other press releases or public announcements concerning this Agreement without the prior written consent of the other Party (which shall not be unreasonably withheld or delayed), except (i) the Buyer and Seller shall each be entitled to issue a press release with respect to the execution of this Agreement, in a form attached as Exhibit E-1 and Exhibit G hereto, respectively, and (iii) as required by a Governmental Entity or applicable Legal Requirement (including the rules and regulations of any stock exchange or trading market on which a Party’s (or its parent entity’s) securities are traded); provided that the Party intending to disclose such information shall provide the other Party with advance notice of such required disclosure, and provide the other Party a reasonable opportunity to review and comment on such proposed disclosure (which comments shall be considered in good faith by the disclosing Party). Each Party acknowledges that the other Party, or the other Party’s parent entity, as a publicly traded company, is legally obligated to make timely disclosures of material events relating to its business. The Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities and Exchange Commission (the “SEC”). Without limiting the foregoing, any Party so obligated shall request confidential treatment of this Agreement pursuant to applicable rules under the Securities Exchange Act of 1934, as amended, and the Freedom of Information Act and the rules promulgated thereunder to permit the filing of a redacted exhibit, provided that there is no assurance that such request will be granted by the SEC and the SEC may require filing of the Agreement in full. Notwithstanding the foregoing, without prior submission to or approval of the other Party, either Party may issue press releases or public announcements which incorporate information concerning this Agreement which information was included in a press release or public disclosure which was previously disclosed under the terms of this Agreement or which contains only non-material factual information regarding this Agreement.

ARTICLE XII
GENERAL PROVISIONS

12.1 Survival. Except as expressly set forth herein, the representations and warranties contained in this Agreement, and liability for the breach thereof, shall survive the Closing Date and shall remain in full force and effect for a period of two (2) years following the Closing Date; provided, however, that the representations and warranties contained in Sections 5.1, 5.2, 5.5, 5.11, 5.12 and 5.13 hereof, shall, in each case, survive the Closing Date and remain in full force and effect until the expiration of the applicable statute of limitations.

12.2 Transfer Taxes and Fees. Notwithstanding any other provision in this Agreement to the contrary, each respective Party shall bear and pay any and all sales taxes, value added taxes, use taxes, transfer taxes, documentary charges, recording fees or similar taxes, charges, or fees (including any

12.3 Priority Review Fee. The priority review user fee described in section 529(c) of the FDC Act (21 U.S.C. § 360ff(c)) (the “Priority Review Fee”) and all other user fees under the FDC Act applicable to the human drug application for which the Priority Review Voucher is redeemed, following the Closing shall be borne exclusively by the Buyer, its Affiliates or any transferee of the Priority Review Voucher. In any event, Seller shall have no liability or obligation for any such fees. In furtherance and not in limitation of the foregoing, Buyer shall timely pay all amounts due with respect to the Priority Review Fee in connection any submission of a Pre-Closing PRV Notice as contemplated by Section 4.1 or other Notice of Intent to Use the Priority Review Voucher by Buyer.

12.4 Notices. Any notice or other communication required or permitted to be delivered to any Party shall be in writing and shall be deemed properly delivered, given and received: (a) when delivered by hand; or (b) upon such Party’s receipt after being sent by registered mail, by courier or express delivery service, in any case to the address set forth beneath the name of such Party below (or to such other address as such Party shall have specified in a written notice given to the other Party in accordance with this Section 12.3):

12.5 Construction.

(a) The Parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting Party shall not be applied in the construction or interpretation of this Agreement.

(b) As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

(c) Except as otherwise indicated, all references in this Agreement to “Articles” and “Sections” are intended to refer to Articles and Sections of this Agreement.

12.6 Counterparts. This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same instrument, and shall become effective when one or more counterparts have been signed by each of the Parties hereto and delivered to the other Party hereto, it being understood that all Parties hereto need not sign the same counterpart. The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission or facsimile shall be sufficient to bind the Parties hereto to the terms and conditions of this Agreement.

12.7 Entire Agreement. This Agreement, including all exhibits and schedules attached hereto, sets forth the entire understanding of the Parties relating to the subject matter hereof and supersedes all prior agreements and understandings among or between the Parties relating to the subject matter hereof.

12.8 Assignment. No Party will have the right to assign this Agreement, in whole or in part, by operation of law or otherwise, without the other Party’s express prior written consent. Any attempt to assign this Agreement without such consent, will be null and void. Notwithstanding the foregoing, any Party may assign this Agreement, in whole or in part, without the consent of the other Party: (a) to a Third Party that succeeds to all or substantially all of its assets or business related to this Agreement (whether by sale, merger, operation of law or otherwise); or (b) to an Affiliate of such Party. Notwithstanding the foregoing, Buyer may assign this Agreement, in whole or in part, without Seller’s consent, to any purchaser, transferee, or assignee of any of the Transferred Rights. For the avoidance of doubt, no assignment made pursuant to this Section 12.7 shall relieve the assigning Party of any of its obligations under this Agreement. Subject to the foregoing, this Agreement will bind and inure to the benefit of each Party’s successors and permitted assigns.

12.9 Severability. If any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the Parties hereto. The Parties hereto shall use commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

12.10 Remedies Cumulative. 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.

12.11 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of law. The Parties irrevocably and unconditionally submit to the exclusive jurisdiction of the United States District Court for the Southern District of New York (or if such court does not have subject matter jurisdiction, State Court of the State of New York located in New York County) solely and specifically for the purposes of any action or proceeding arising out of or in connection with this Agreement.

12.12 Amendment; Extension; Waiver. Subject to the provisions of applicable law, the Parties hereto may amend this Agreement at any time pursuant to an instrument in writing signed on behalf of each of the Parties hereto. At any time, any Party hereto may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Party hereto, (b) waive any inaccuracies in the representations and warranties made to such Party contained herein or (c) waive compliance with any of the agreements or conditions for the benefit of such Party contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. Without limiting the generality or effect of the preceding sentence, no delay in exercising any right under this Agreement shall constitute a waiver of such right, and no waiver of any breach or default shall be deemed a waiver of any other breach or default of the same or any other provision in this Agreement.

12.13 Representation By Counsel; Interpretation. Seller and Buyer each acknowledge that it has been represented by its own legal counsel in connection with this Agreement and the transactions contemplated by this Agreement. Accordingly, any rule of law, or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the Party that drafted it, has no application and is expressly waived.

12.14 Expenses. Whether or not the purchase and sale of the Transferred Rights and the other transactions contemplated by this Agreement are consummated, and except as otherwise set forth in this Agreement, each of the Parties shall bear its own fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby.
