5.8Compliance with Legal Requirements.  Seller shall, and shall cause its Affiliates and each of their respective successors in interest and assigns to the Rare Pediatric Disease Product Application, to comply at all times with all Legal Requirements applicable to such Persons (as the sponsor of such Rare Pediatric Disease Product Application and the initial recipient and owner of the Priority Review Voucher, as applicable), in any case relating to the Purchased Assets, including any and all Legal Requirements applicable to the validity, maintenance, use or transfer of the Priority Review Voucher.  Seller shall promptly forward to Buyer any written communications or notices (and shall promptly notify Buyer of any oral communications or notices) it or its Affiliates receive from any Governmental Entity in respect of, or that would reasonably be expected to adversely impact in any material respect, the Purchased Assets; provided that Seller may redact any portion of such written communications or other notices that is not relevant to the Purchased Assets.  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 maintenance, 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 and

17

assigns to the Rare Pediatric Disease Product Application, to submit a post-approval production report to the FDA not later than five (5) years after the FDA Approval in accordance with Section 529(e)(2) of the FFDCA.

5.9Marketing. Seller shall, and shall cause its Affiliates and each of their respective successors in interest and assigns to, within Marketing Period, Market in the United the Rare Pediatric Disease Product to the extent and in a manner required, now or in the future, under applicable Legal Requirements or otherwise by any applicable Governmental Entity to preclude the FDA from exercising its authority to revoke the Priority Review Voucher pursuant to Section 529(e)(1) of the FFDCA or as otherwise required for the use or transfer of the Priority Review Voucher. Seller shall promptly forward to Buyer copies of any written communications  it or its Affiliates receive from, or send to, the FDA relating to the anticipated or actual marketing status of the Rare Pediatric Disease Product, including, without limitation, any marketing status notification under section 506I of the FFDCA and any related correspondence. Promptly following any request in writing by Buyer, Seller shall notify Buyer in writing as to whether the Marketing requirement described in the immediately preceding sentence has been satisfied.

5.11Confidentiality.

(a)With respect to Confidential Information received by any Party, such Party shall (i) keep such Confidential Information confidential, (ii) not use such Confidential Information for any reason other than to carry out the intent and purpose of this Agreement, and (iii) 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.

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. For the avoidance of doubt, this Section 5.11(c) does not apply to those disclosures concerning this Agreement to which Section 5.6 applies.

(d)Nothing herein shall prohibit or otherwise restrict the disclosure of any Confidential Information by or on behalf of Buyer or its Affiliates to the FDA or other Governmental Entity to the extent required by the FDA or such other Governmental Entity to enable the use or transfer of the Priority Review Voucher; provided, that Buyer, its Affiliates and their respective Representatives shall use commercially reasonable efforts to obtain confidential treatment for any such disclosures. Further, nothing herein shall prohibit or otherwise restrict public announcements permitted by, and made in accordance with, Section 5.6 and 5.7.

5.12Disclosure Concerning Use of the Priority Review Voucher.  In the event that Buyer or any of its Affiliates uses (or notifies the FDA of its intent to use) the Priority Review Voucher in connection with a human drug application, Buyer or such Affiliate may, in any press release, public announcement or other disclosure relating to its filing (or proposed filing) of the relevant human drug application, disclose that the Priority Review Voucher acquired from Seller has been used (or is intended to be used) in connection with such human drug application.

8.2Notice of Loss.

(a)In order for an Indemnified Party to be entitled to any indemnification provided for under Section 8.1(a) or 8.1(b) in respect of, arising out of or involving a Third Party Claim, such Indemnified Party must notify the applicable Indemnifying Party in writing of the Third Party Claim (including in such notice a brief description of the applicable claim(s), including damages sought or estimated, to the extent actually known by such Indemnified Party) within 20 Business Days after receipt by such Indemnified Party of actual notice of the Third Party Claim and prior to the end of the applicable survival period under Section 8.3; provided, however, that failure to give such notification shall not affect the indemnification provided under Section 8.1(a) or 8.1(b) except to the extent the Indemnifying Party has been actually and materially prejudiced as a result of such failure.

(b)If the Indemnifying Party has acknowledged in writing to the Indemnified Party the Indemnifying Party’s responsibility for defending and indemnifying the Indemnified Party with respect to such Third Party Claim (subject to the limitations set forth in Section 8.6), the Indemnifying Party shall have the right to defend (with counsel reasonably selected by the Indemnifying Party and approved by the Indemnified Party, such approval not to be unreasonably withheld, conditioned or delayed), at its sole cost and expense, such Third Party Claim (other than a class action, a criminal matter or a claim in which non-monetary equitable or injunctive relief against the Indemnified Party is sought) by all appropriate proceedings, which proceedings shall

23

be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party; provided, however, that the Indemnifying Party 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 Indemnified Party of a release from all liability in respect of such Third Party Claim; and (ii) the Indemnified Party 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 Indemnified Party, (B) any payment by the Indemnified Party that is not indemnified hereunder or (C) the imposition of any equitable relief against the Indemnified Party, in which case for clauses (A) - (C) above, the Indemnified Party may withhold its consent in its sole discretion.  If the Indemnifying Party 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 Indemnifying Party, the Indemnified Party shall have the right, at the expense of the Indemnifying Party, upon at least ten (10) Business Days’ prior written notice to the Indemnifying Party of its intent to do so, to undertake the defense of such Third Party Claim for the account of the Indemnifying Party (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying Party, such approval not to be unreasonably withheld or delayed), provided, that the Indemnified Party shall keep the Indemnifying Party apprised of all material developments with respect to such Third Party Claim and promptly provide the Indemnifying Party with copies of all correspondence and documents exchanged by the Indemnified Party and the opposing party(ies) to such litigation.  The Indemnified Party may not compromise or settle such litigation without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld or delayed.

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

(d)In order for an Indemnified Party to be entitled to any indemnification provided for under this Agreement other than in respect of, arising out of or involving, a Third Party Claim, such Indemnified Party shall deliver notice of such claim with reasonable promptness to the Indemnifying Party (including in such notice a brief description of the applicable claim(s), including damages sought or estimated, to the extent actually known by such Indemnified Party, and the Section(s) of this Agreement upon which such claim for indemnification is then based); provided, however, that failure to give such notification shall not affect the indemnification provided under Section 8.1(a) or 8.1(b) except to the extent the Indemnifying Party has been actually and materially prejudiced as a result of such failure.

8.3Survival.  The representations and warranties of Seller and Buyer under 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 all covenants, the Fundamental Representations and any claims for fraud shall survive the Closing Date and shall remain in full force and effect until the later of (a) six (6) years following the Closing Date and (b) the expiration of the applicable statute of limitations.  No claim for breach of any representation, warranty, covenant or agreement may be brought after expiration of the

24

survival periods set forth in this Section 8.3.  Notwithstanding the foregoing, if written notice of a claim has been given in the manner required by Section 8.2 prior to the expiration of the applicable survival period by the Party seeking indemnification for such claim, then the relevant covenants, representations and warranties of the other Party shall survive as to such claim until such claim has been finally resolved pursuant to this Article 8.

8.4Additional Indemnification Matters.  Except to the extent that the applicable representation or warranty is qualified by Knowledge, the right of indemnification provided under this Article 8 shall not be affected by any knowledge acquired (or capable of being acquired) at any time, whether before or after the Effective Date, with respect to the accuracy or inaccuracy of, or compliance or noncompliance with, any representation, warranty, covenant or agreement contained herein.

8.5Adjustments.  Any amount paid under this Article 8 shall be treated as an adjustment to the Purchase Price for all Tax purposes unless otherwise required by applicable Law.

8.6Additional Limitations of Liability.  Notwithstanding anything to the contrary set forth in this Agreement, except in the case of fraud, the maximum aggregate amount of indemnifiable Losses that may be recovered from Seller by the Buyer Indemnified Parties on the one hand, or by Buyer from the Seller Indemnified Parties on the other hand, shall equal the Purchase Price.  NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH IN THIS AGREEMENT, EXCEPT TO THE EXTENT ACTUALLY AWARDED AGAINST AN INDEMNITEE PURSUANT TO A JUDGMENT WITH RESPECT TO A THIRD PARTY CLAIM, EACH PARTY HERETO WAIVES (I) ANY CLAIM FOR PUNITIVE, EXEMPLARY, MULTIPLIED, INDIRECT, CONSEQUENTIAL, LOST PROFITS, OR LOST REVENUE DAMAGES, AND (II) ANY CLAIM FOR ATTORNEY FEES, COSTS AND PREJUDGMENT INTEREST.  The limitations specified in this Section 8.6 will survive the termination of the Agreement.

8.7Exclusive Remedy.  From and after the Closing, this Article 8 will provide the exclusive remedy against either Party for any breach of any representation, warranty, covenant or other claim arising out of or relating to this Agreement and/or the transactions contemplated hereby, 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 or making any claim in the event of fraud.  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 hereby, 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.

9.2Construction.  Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or).  Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days.  The captions of this Agreement are for convenience of reference only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement.  The term “including,” “include,” or “includes” as used herein shall mean “including, but not limited to,” and shall not limit the generality of any description preceding such term.  The words “will” and “shall” have the same meaning.  “Extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if.” The language of this Agreement shall be deemed to be the language mutually chosen by the

26

Parties and no rule of strict construction shall be applied against either Party hereto.  Each Party represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof.  In interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and provisions.

9.3References.  Unless otherwise specified, (a) references in this Agreement to any Article, Section, Schedule or Exhibit shall mean references to such Article, Section, Schedule or Exhibit of this Agreement, (b) references in any Section to any clause are references to such clause of such Section, and (c) references to any agreement, instrument, or other document in this Agreement refer to such agreement, instrument, or other document as originally executed or, if subsequently amended, replaced, or supplemented from time to time, as so amended, replaced, or supplemented and in effect at the relevant time of reference thereto.

9.4Entire Agreement; Amendments.  This Agreement, the documents, Exhibits and Schedules referred to herein, and the Confidentiality Agreement sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises, and representations, whether written or oral, with respect thereto are superseded hereby.  Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth in this Agreement.  No amendment, modification, release, or discharge shall be binding upon the Parties unless in writing and duly executed by authorized Representatives of both Parties.

9.5Assignment.  Without the prior written consent of the other Party neither Party shall sell, transfer, assign, delegate, pledge, or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, that Buyer may make such an assignment, in whole or in part, without Seller’s consent, to any Affiliate, purchaser, transferee, or assignee of the Purchased Assets.  With respect to any permitted assignment, the assigning Party shall remain responsible for the performance by such permitted assignee of the assigning Party’s duties and obligations hereunder.  Any attempted assignment or delegation in violation of this Section 9.5 shall be void and of no effect.  All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Buyer or Seller, as the case may be.

9.6Severability.If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable; (b) this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom; and (d) in lieu of such illegal, invalid, or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and reasonably acceptable to the Parties.  To the fullest extent permitted by applicable Law, each Party hereby waives any provision of Law that would render any provision hereof illegal, invalid, or unenforceable in any respect.

27

9.7Governing Law.  This Agreement or the performance, enforcement, breach or termination hereof shall be interpreted, governed by and construed in accordance with the laws of the State of New York, United States, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

9.8Mediation.

(a)The Parties shall first attempt to resolve any dispute, controversy or claim arising out of or related to this Agreement (“Dispute”) by confidential mediation in accordance with the then current mediation procedure (“CPR Mediation Procedure”) of the International Institute for Conflict Prevention and Resolution (www.cpradr.org) before initiating litigation.  The CPR Mediation Procedure shall control, except where it conflicts with this Section 9.8, in which case this Section 9.8 shall control.  The mediator shall be chosen pursuant to the CPR Mediation Procedure.  The mediation shall be held in New York, New York.  All aspects of the mediation shall be treated as confidential.

(b)Either Party may initiate mediation by written notice to the other Party of the existence of a Dispute.  The Parties shall select a mediator within 30 days of the notice and the mediation will begin promptly after the selection.  The mediation will continue until the mediator, or either Party, declares in writing, no sooner than after the conclusion of one full day of a substantive mediation conference attended on behalf of each Party by a senior business person with authority to resolve the Dispute, that the Dispute cannot be resolved by mediation.  In no event, however, shall mediation continue for more than 60 days from initial notice by a Party to initiate meditation, unless the Parties agree in writing to extend that period.

(c)Any period or statute of limitations that would otherwise expire between the initiation of mediation and its conclusion shall be extended until 20 days after the conclusion of the mediation.

(d)The parties may jointly opt out of the mediation procedure by written mutual agreement.

(e)Either Party has the right to seek from the appropriate court provisional remedies such as attachment, preliminary injunction, replevin, etc. to avoid irreparable harm, maintain the status quo, or preserve the subject matter of the Dispute.

(f)Notwithstanding anything to the contrary in this Agreement, the foregoing provisions of this Section 9.8 shall not apply to any Dispute related to the failure of either Party to perform its obligations required to be performed prior to the Closing pursuant to this Agreement (including failing to take such actions as are required of them hereunder to consummate the Closing) in accordance with its specified terms, and instead the provisions of Section 9.9 shall apply to any such Dispute.

9.9Dispute Resolution.

(a)if the Parties fail to resolve any applicable Dispute in mediation or if Section 9.8(e) applies, and a Party desires to pursue resolution of the applicable Dispute, such Dispute may

28

be submitted by such Party for resolution exclusively in the United States District Court for the Southern District of New York, or in New York State Supreme Court in the Borough of Manhattan if the United States District Court does not have jurisdiction.  Each of the Parties (i) consents to the exclusive jurisdiction of each such court with respect to resolution of such Dispute, (ii) waives any objection that it may have to the laying of venue in any such suit, action or proceeding in any such court, and (iii) agrees that service of any court paper may be made in such manner as may be provided under applicable laws or court rules governing service of process or by registered mail to such Party’s address set forth in Section 9.1.

(b)The Parties agree to seek an early conference with the court and to advise the court of this Agreement.  The Parties agree to make all filings required by the court on a schedule that will assure trial ready status eight months after the service of the first complaint and further agree to make all motions, including motions for summary judgment, on a schedule that will allow them to be fully considered by the court less than eight months after the service of the first complaint.

(c)Both Parties agree to conduct discovery in a manner and on a schedule to assure completion of discovery within five months after service of the first complaint.  To that end, each of the Parties agrees to pursue no more than the following discovery in the aggregate from all parties and non-parties to the action: a total of no more than 15 requests for documents (including subparts); a total of no more than 15 interrogatories (including subparts); a total of no more than 40 hours of deposition testimony from all witnesses in the aggregate, including both fact and expert witnesses; and a total of no more 20 hours of non-party witnesses.  The Parties agree to work together to reach agreement to limit discovery of electronically stored information, including the use of date restrictions and file types.  To obtain email, the parties to the Dispute must propound specific email production requests directed to specific issues, rather than general discovery.  Email production requests shall identify the custodian, search terms, and time frame and be limited to a total of five custodians and five search terms.

(d)Each Party has the right to pursue provisional relief from any court, such as attachment, preliminary injunction, replevin, etc. to avoid irreparable harm, maintain the status quo, or preserve the subject matter of the Dispute.

9.10WAIVER OF JURY TRIAL.  EACH PARTY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR OTHER LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS IT CONTEMPLATES.  THIS WAIVER APPLIES TO ANY ACTION OR LEGAL PROCEEDING, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE.

9.11Waiver and Non-Exclusion of Remedies.

(a)Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition.  The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach

29

or failure by such other Party whether of a similar nature or otherwise, and nothing in this Agreement shall be deemed a waiver by any Party of any right to specific performance or injunctive relief.  The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by applicable Law or otherwise available except as expressly set forth herein.

(b)The Parties agree that irreparable harm would occur in the event that the Closing is not consummated in accordance with the terms of this Agreement, and that money damages or other legal remedies would not be an adequate remedy for any such harm.  Accordingly, the Parties acknowledge and hereby covenant and agree that in the event of any breach or threatened breach of the covenants, agreements or obligations set forth in this Agreement, then in addition to any other remedy available at law or in equity, the non-breaching Party will be entitled to an injunction or injunctions to prevent or restrain any breaches or threatened breaches of this Agreement, and to specifically enforce the terms and provisions of this Agreement to enforce compliance with the covenants, agreements and obligations under this Agreement.  Each Party hereby covenants and agrees not to raise, and irrevocably waives, any objections to the availability of such relief that a remedy at law would be adequate and that a bond or other security will be required.

9.12No Benefit to Third Parties.  Except as provided in Article 8, the covenants and agreements set forth in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they shall not be construed as conferring any rights on any other Persons.

9.13Counterparts; Execution.  This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one (1) and the same instrument.  This Agreement may be executed by electronically transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were original signatures.
