Promptly (but in no event later than ten (10) days) after the receipt by any Indemnified Party of a notice of any Proceeding by any Third Party that may be subject to indemnification under thisArticle IX, including any Proceeding relating to any Excluded Liability or Assumed Liability, such Indemnified Party shall give written notice of such Proceeding to the Indemnifying Party, stating in reasonable detail the nature and basis of each claim made in the Proceeding and the amount thereof, to the extent known, along with copies of the relevant documents received by the Indemnified Party evidencing the Proceeding and the basis for indemnification sought. Failure of the Indemnified Party to give such notice shall not relieve the Indemnifying Party from liability on account of this indemnification, except if and only to the extent that the Indemnifying Party is actually prejudiced thereby. Thereafter,

43

the Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Proceeding. The Indemnifying Party shall have the right to assume the defense of the Indemnified Party against the Third Party Claim upon written notice to the Indemnified Party delivered within thirty (30) days after receipt of the particular notice from the Indemnified Party; provided, however, that the Indemnifying Party shall not have the right to assume the defense of the Third Party Claim if such Third Party Claim (x) seeks as a remedy the imposition of an equitable remedy that is binding upon Purchaser, Parent or Opco, the Purchased Assets or the Assumed Liabilities or (y) the amounts of Losses would be reasonably expected to exceed the amounts for which the Indemnifying Party is obligated to indemnify. So long as the Indemnifying Party has assumed the defense of the Third Party Claim in accordance herewith and notified the Indemnified Party in writing thereof, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, it being understood that the Indemnifying Party shall pay all reasonable costs and expenses of counsel for the Indemnified Party after such time as the Indemnified Party has notified the Indemnifying Party of such Third Party Claim and prior to such time as the Indemnifying Party has notified the Indemnified Party that it has assumed the defense of such Third Party Claim, (ii) the Indemnified Party shall not file any papers or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be unreasonably withheld, conditioned or delayed) and (iii) the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim (other than a judgment or settlement that is solely for money damages in an amount less than the remaining balance of the limitations on indemnity set forth inSection 9.2 and is accompanied by a release of all indemnifiable claims against the Indemnified Party) without the prior written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed). Whether or not the Indemnifying Party shall have assumed the defense, such Indemnifying Party shall not be obligated to indemnify and hold harmless the Indemnified Party hereunder for any settlement entered into without the Indemnifying Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(b)Equitable Remedies. In the case of any Third Party Claims where the Indemnifying Party reasonably believes that it would be appropriate to settle such claim using equitable remedies (i.e., remedies involving the future use of the Purchased Assets), the Indemnifying Party and the Indemnified Party shall work together in good faith to agree to a settlement; provided, however, that no Party shall be under any obligation to agree to any such settlement.

(c)Treatment of Indemnification Payments; Insurance Recoveries. Any payment made pursuant to the indemnification obligations arising under this Agreement shall be treated as an adjustment to the Purchase Price to the extent allowable under Applicable Law. Any indemnity payment under this Agreement shall be decreased by any amounts actually received by the Indemnified Party under Third Party insurance policies with respect to such Damage prior to the time payment by the Indemnifying Party is due and payable under this Agreement (net of any premiums paid by such Indemnified Party under the relevant insurance policy and any costs incurred by such Indemnified Party in procuring such payment under such policy), each Party agreeing (i) to use commercially reasonable efforts to recover all available insurance proceeds

and (ii) to the extent that any indemnity payment under this Agreement has been paid by the Indemnifying Party to or on behalf of the Indemnified Party prior to the receipt, directly or indirectly, by the Indemnified Party of any net insurance proceeds under Third Party insurance policies on account of such Loss which duplicate, in whole or in part, the payment made by the Indemnifying Party to or on behalf of the Indemnified Party, the Indemnified Party shall remit to the Indemnifying Party an amount equal to the amount of the net insurance proceeds actually received by the Indemnified Party on account of such Loss which duplicate, in whole or in part, the payment made by the Indemnifying Party to or on behalf of the Indemnified Party.

Each Indemnification Claim Notice must contain a reasonable description of the claim and the nature and amount of such Losses (to the extent the nature and amount of such Losses are known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party (but in no event more than thirty (30) days after discovery) copies of all papers and official documents received in respect of any Losses. All indemnification claims in respect of a Party, its Affiliates or their respective directors, stockholders, members, officers, managers, employees and agents shall be made solely by such Party to this Agreement.

Parent hereby agrees to be responsible for, and guarantee to Seller, the full performance by Purchaser, a wholly-owned subsidiary of Parent, and Opco, an indirect, wholly-owned subsidiary of Purchaser, and agrees to cause Purchaser and Opco to perform, all of their respective obligations and liabilities under or in connection with this Agreement, the Ancillary Agreements and the transactions contemplated hereby and thereby. The liability of Parent under thisSection 9.5 shall be irrevocable, absolute and independent.

Section 9.6Remedies Exclusive. Following the Closing, with the exception of remedies based on fraud, the remedies set forth in thisArticle IX shall constitute the sole and exclusive remedy for money damages and shall be in lieu of any other remedies for money damages that may be available to the Indemnified Parties under any other agreement or pursuant to any statutory or common law with respect to any Losses of any kind or nature incurred directly or indirectly resulting from or arising out of any of this Agreement, the Purchased Assets, the Assumed Liabilities or the Excluded Liabilities (it being understood that nothing in thisSection 9.6 or elsewhere in this Agreement shall affect the Parties’ rights to specific performance or other similar non-monetary equitable remedies with respect to the covenants referred to in this Agreement to be performed after the Closing). The Parties each hereby waive any provision of any Applicable Law to the extent that it would limit or restrict the agreement contained in thisSection 9.6.

ARTICLE X

MISCELLANEOUS PROVISIONS

Section 10.1Confidentiality.

(a) Reference is made to that certain letter agreement dated July 28, 2011, by and between Seller and Parent (the “Confidentiality Agreement”). As used in thisSection 10.1, the term “Evaluation Material” shall have the meaning assigned to such term in the Confidentiality Agreement. Upon the Closing, the Confidentiality Agreement shall expire and be of no further force and effect with respect to all Evaluation Material relating to the Product Business, the Purchased Assets or the Assumed Liabilities, but all such Evaluation Materials shall thereafter be governed by the provisions ofSection 10.1(b); provided, however, such expiration of the Confidentiality Agreement shall in no way prejudice or adversely affect Seller’s ability to seek damages, or any other remedy available to Seller, with respect to a violation by Purchaser, Parent or Opco (or their respective Affiliates or representatives) of the Confidentiality Agreement prior to or after the Closing. Upon and after the Closing, the Confidentiality Agreement shall remain in full force and effect pursuant to its terms with respect to all other Evaluation Material that does not relate to the Product Business, the Purchased Assets or the Assumed Liabilities.

(b) From and after the Closing, all confidential information and all Evaluation Material relating to the Product Business, the Purchased Assets and the Assumed Liabilities shall constitute the “Purchaser Confidential Information” and shall be used by Seller solely as required to perform its obligations, exercise or enforce its rights under this Agreement (or any Ancillary Agreement), or comply with Applicable Law, and for no other purpose. Seller shall not disclose, or permit the disclosure of, any of the Purchaser Confidential Information to any Person except those Persons to whom such disclosure is necessary to permit Seller to perform its obligations, exercise or enforce its rights under this Agreement (or any Ancillary Agreement), or comply with Applicable Law. Seller shall treat, and will cause its Affiliates and the directors, officers, employees, agents, representatives and advisors of Seller or any of their Affiliates to treat, the Purchaser Confidential Information as confidential, using the same degree of care as Seller normally employs to safeguard its own confidential information from unauthorized use or disclosure, but in no event less than a reasonable degree of care.

(c) All confidential information obtained by Purchaser, Parent or Opco (or their respective Affiliates or representatives) from Seller (or its Affiliates or representatives) other than the Purchaser Confidential Information (the “Seller Confidential Information”) shall be used by Purchaser, Parent and Opco solely as required to perform their respective obligations, exercise or enforce its rights under this Agreement (or any Ancillary Agreement), or comply with Applicable Law, and for no other purpose. Purchaser, Parent and Opco shall not disclose, or permit the disclosure of, any of Seller Confidential Information to any person except those persons to whom such disclosure is necessary to permit Purchaser, Parent and Opco to perform their respective obligations, exercise or enforce their respective rights under this Agreement (or any Ancillary Agreement), or comply with Applicable Law. Purchaser, Parent and Opco shall each treat, and will cause their respective Affiliates and the directors, officers, employees, agents, representatives and advisors of Purchaser, Parent and Opco or any of their Affiliates to treat, Seller Confidential Information as confidential, using the same degree of care as Purchaser,

47

Parent and Opco normally employs to safeguard its own confidential information from unauthorized use or disclosure, but in no event less than a reasonable degree of care.

(d) In the event any Party is requested pursuant to, or required by, Applicable Law to disclose any of any other Party’s Confidential Information (i.e., Seller Confidential Information or Purchaser Confidential Information, as applicable), it will notify the other Party in a timely manner so that such Party may seek a protective order or other appropriate remedy or, in such Party’s sole discretion, waive compliance with the confidentiality provisions of this Agreement. Each Party will co-operate in all reasonable respects, in connection with any reasonable actions to be taken for the foregoing purpose. In any event, the Party requested or required to disclose such Confidential Information may furnish it as requested or required pursuant to Applicable Law (subject to any such protective order or other appropriate remedy) without liability hereunder, provided that such Party furnishes only that portion of the Confidential Information which such Party is advised by a reasoned opinion of its counsel is legally required, and such Party exercises reasonable efforts to obtain reliable assurances that confidential treatment will be accorded such Confidential Information.

(e) Nothing in thisSection 10.1 shall be construed as preventing or in any way inhibiting any Party from complying with Applicable Law governing activities and obligations undertaken pursuant to this Agreement, in any manner which it reasonably deems appropriate, including, for example, by disclosing to Governmental Authorities confidential or other information of the other Party.

Section 10.2Notices. All notices, requests and other communications required or permitted under, or otherwise made in connection with, this Agreement, shall be in writing and shall be deemed to have been duly given (a) when delivered in person, (b) upon confirmation of receipt when transmitted by facsimile transmission, or (c) on the next Business Day if transmitted by national overnight courier (with confirmation of delivery), in each case, addressed as follows:

Section 10.5Further Assurances; Further Cooperation.

From time to time, whether at or after the

49

Closing, (i) Seller shall execute and deliver such further documents or instruments of conveyance, transfer and assignment and take all such other action, at Purchaser’s sole expense, as Purchaser may reasonably require to more effectively convey, transfer and assign to Purchaser any and all ownership, right, title and interest in and to the Purchased Assets, including, without limitation, executing documents or instruments necessary to permit Purchaser to record the transfer, conveyance and/or assignment of any and all Product Intellectual Property with any Governmental Authority and (ii) Purchaser, Parent and Opco will execute and deliver such further instruments and take all such other action, at Seller’s sole expense, as Seller may reasonably require to more effectively assume the Assumed Liabilities. Upon reasonable request and during normal business hours, Purchaser, Parent, Opco and Seller shall cooperate with each other, and shall cause their respective representatives and Affiliates to cooperate with each other, after the Closing to ensure the orderly transition of the Purchased Assets and Assumed Liabilities to Purchaser and to minimize any disruption to the businesses of Seller, Purchaser, Parent and Opco that might result from the transactions contemplated hereby.

Section 10.6Amendments and Waivers.

(a) Any provision of this Agreement may be amended or waived but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each Party to this Agreement or, in the case of a waiver, by the Party against whom the waiver is to be effective. No waiver by any Party hereto of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement or any future occasions.

(b) No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 10.7Expenses. Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement, including all third-party legal, accounting, financial advisory, consulting or other fees and expenses incurred in connection with the transactions contemplated hereby, shall be paid by the Party incurring such cost or expense.

Section 10.8Binding Effect; Benefit; Assignment.

(a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and assigns. Except as provided under this Agreement, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the Parties and their respective successors and assigns.

(b) Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party hereto (other than to an Affiliate of the Party) without the prior written consent of the other Party hereto (which consent shall not be unreasonably withheld) and any attempt to do so will be void;provided,however, that after the Closing, such prior written

50

consent will not be required with respect to any assignment by any Party (a) to an Affiliate of such Party so long as such Party remains bound by the terms hereof, or (b) in connection with a reorganization, merger, statutory share exchange, consolidation or similar change of control transaction involving the Seller or sale or transfer of all or substantially all of the assets of Seller, or, in the case of Purchaser, a sale or transfer, regardless of form, involving all or substantially all of the assets associated with the Product Business. Except with respect toSection 8.14(a) of this Agreement which shall not apply to non-affiliated successors or assigns of Seller, and except with respect toSection 8.14(b) of this Agreement which shall not apply to non-affiliated successors or assigns of Purchaser, Parent and Opco, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties hereto and their respective successors and permitted assigns. For the avoidance of doubt, all obligations pursuant toSection 8.14(a) shall automatically and immediately terminate and cease to be enforceable against any non-affiliated successor or assign of Seller and all obligations pursuant toSection 8.14(b) shall automatically and immediately terminate and cease to be enforceable against any non-affiliated successor of Parent, Purchaser or Opco. Any attempt to assign this Agreement in violation of thisSection 10.8(b) shall be void. Subject to thisSection 10.8(b), any permitted assignee shall assume all obligations of its assignor under this Agreement pursuant to a written instrument reasonably acceptable to the other Parties. In addition, nothing in this Agreement shall preclude Purchaser from providing its lenders with a security interest in its rights under this Agreement in accordance with the terms of their security and collateral agreements in connection with any credit facility provided by such lenders to Purchaser or preclude such lenders from foreclosing upon such security interest in accordance with the terms of such security and collateral agreements (including, without limitation, by means of the sale of the assets or stock of Purchaser to a Third Party including Purchaser’s rights and responsibilities under this Agreement), and any such action by such lenders shall not be deemed to be a change of control for purposes of this Agreement.

(c) Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the Parties and their respective successors and permitted assigns any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 10.9Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of laws that would require the application of the laws of any other jurisdiction.

Section 10.10Jurisdiction. The Parties hereto agree that any Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal court located in the State of Delaware or any Delaware state court, and each of the Parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such Proceeding in any such court or that any such Proceeding brought in any such court has been brought in an inconvenient forum. Process in any such Proceeding may be served on any Party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each Party agrees that service of process on such party as provided inSection 10.2 shall be deemed effective service of process on such Party.

51

Section 10.11Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 10.12Arbitration.

(a) With respect to any dispute, controversy or claim arising from or related to this Agreement or the breach thereof that is not an Excluded Claim (“Dispute”), such Dispute shall first be referred to an executive officer from each Party for attempted resolution by good faith negotiations. Any such Dispute shall be submitted to such senior executives no later than thirty (30) days following such request by any Party. Such executives shall attempt in good faith to resolve any such Dispute within thirty (30) days after the submission of the Dispute. In the event the executives are unable to resolve the Dispute, the Parties shall otherwise negotiate in good faith and use reasonable efforts to settle. If the Parties do no fully settle, and a Party wishes to pursue the matter, each such Dispute shall be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes of the American Arbitration Association (“AAA”), and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

(b) The arbitration shall be conducted by a panel of three (3) persons experienced in the pharmaceutical business: within thirty (30) days after initiation of arbitration, each of Purchaser and Seller shall select one person to act as arbitrator and the two selected arbitrators shall select a third arbitrator within thirty (30) days of their appointment. If the arbitrators selected by Purchaser and Seller are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the AAA. The place of arbitration shall be San Francisco, California, and all proceedings and communications shall be in English.

(c) Any Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Any Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration.

(d) Except to the extent necessary to confirm an award or as may be required by law, no Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of each Party. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable Delaware statute of limitations.

(e) For clarity, thisSection 10.12 shall not apply to any Excluded Claim with the result that Excluded Claims shall not be subject to resolution by arbitration in the absence of a separate agreement between the Parties to do so.

52

Section 10.13Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each Party shall have received a counterpart hereof signed by the other Party. Until and unless each Party has received a counterpart hereof signed by the other Party hereto, this Agreement shall have no effect, and no Party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication). The exchange of a fully executed Agreement or any Ancillary Agreement (in counterparts or otherwise) by electronic transmission in .PDF format or by facsimile shall be sufficient to bind the Parties to the terms and conditions hereof and thereof.

Section 10.14Entire Agreement. This Agreement, the Ancillary Agreements, the Confidentiality Agreement and each of the documents, instruments and agreements delivered in connection with the transactions contemplated by this Agreement, including each of the Exhibits, the Schedules, and the Seller Disclosure Schedule, constitute the entire agreement between the Parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the Parties with respect to the subject matter of this Agreement.

Section 10.15Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 10.16Time is of the Essence. Time is of the essence with respect to the performance of this Agreement.
