STOCK PURCHASE AGREEMENT, dated as of March 29, 2016 (this “Agreement”), between Eisai Inc., a Delaware corporation (“Seller”), and PBM AKX Holdings, LLC, a Delaware limited liability company (“Purchaser”).  Seller and Purchaser are sometimes referred to herein individually as a “Party” and collectively as the “Parties.”

RECITALS

WHEREAS, Seller directly owns all of the issued and outstanding shares of capital stock (the “Shares”) of AkaRx, Inc., a Delaware corporation (the “Company”);

WHEREAS, Purchaser wishes to purchase from Seller, and Seller wishes to sell to Purchaser, at the Closing, the Shares, upon the terms and subject to the conditions of this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual agreements and covenants hereinafter set forth, and intending to be legally bound, Seller and Purchaser hereby agree as follows:

ARTICLE I

PURCHASE AND SALE

SECTION 1.01.                    Purchase and Sale; Consideration.  Upon the terms and subject to the conditions of this Agreement, at the Closing, Seller shall sell, transfer, assign and deliver to Purchaser, and Purchaser shall purchase, acquire and accept from Seller, the Shares.  The purchase and sale of the Shares is referred to in this Agreement as the “Acquisition”.  In consideration for the Shares, Purchaser shall pay to Seller: (a) $5,000,000 (such amount, the “Closing Payment”), payable as set forth in Section 2.02(b), and (b) the Milestone Payments, as and to the extent provided in Section 1.02.

SECTION 1.02.                    Annual Net Sales Milestone Payments.

(a)           For each Calendar Year commencing with the first Calendar Year in which there are any Net Sales, if Net Sales for a Calendar Year fall in any of the ranges specified in the “Annual Net Sales” column of the table below, Purchaser shall, subject to this Section 1.02, pay to Seller (each such payment, a “Milestone Payment” and, collectively with the Closing Payment, the “Cash Payments”) the amount set forth in the “Milestone Payment” column of the table below opposite the Net Sales range in which Net Sales for such Calendar Year falls.

[***] = Portions of this exhibit have been omitted and filed separately with the Securities and Exchange Commission.  Confidential treatment requested under 17 C.F.R. Sections 200.80(b)(4) and  230.406.

Notwithstanding the foregoing, in no event shall the aggregate amount of the Milestone Payments paid to Seller hereunder exceed $135,000,000 (the “Milestone Payment Cap”).  In the event a Milestone Payment otherwise due and payable hereunder would result in an aggregate amount of Milestone Payments greater than $135,000,000 being paid to Seller, then only such portion of the applicable Milestone Payment that would result in the aggregate amount of Milestone Payments equaling $135,000,000 shall be due and payable.  Purchaser shall have the right to set off against, and deduct from, any Milestone Payments owed to Seller under this Section 1.02(a) the aggregate amount of any Services Fees and Out-of-Pocket Costs (as defined in the Transition Services Agreement) actually paid or reimbursed to Seller in cash under the Transition Services Agreement (including through payment of the principal amount of the Note) in excess of the Aggregate Expense Amount (as defined in the Transition Services Agreement) that have not previously been deducted from Milestone Payments pursuant to this sentence.  Purchaser shall not have the right to set off against, or deduct from, any Milestone Payments owed to Seller under this Section 1.02(a) any accrued interest payable under the Transition Services Agreement or the Note.

For the avoidance of doubt, (i) in no event shall more than one Milestone Payment be due and payable for any single Calendar Year, and (ii) no Milestone Payment is payable with respect to any Calendar Year if Net Sales for such Calendar Year are not at least $[***].

(b)           Purchaser shall pay Seller any Milestone Payments due and owing pursuant to Section 1.02(a) within 60 days after the end of each Calendar Year, beginning with the Calendar Year in which there first are Net Sales.

(c)           Notwithstanding anything to the contrary in this Agreement, upon the occurrence of an Insolvency Event with respect to Purchaser or any affiliate of Purchaser that controls Purchaser, 100% of the then-unpaid Milestone Payments that have become payable upon the achievement of any applicable annual Net Sales target pursuant to Section 1.02(a) shall be accelerated and become immediately due and payable; provided, however, that in a case under Title 11 of the Code, if Purchaser assumes this Agreement in accordance with Section 365 of Title 11 of the Code and cures any and all outstanding defaults, including any and all monetary and non-monetary defaults, within five Business Days of entry following an order authorizing such assumption, then any such Milestone Payments shall not be deemed accelerated in accordance with this Section 1.02(c), but shall remain due and payable in accordance with the terms and subject to the conditions set forth in Section 1.02(a) and Section 1.02(b).  Nothing in this Agreement shall be construed, explicitly or implicitly, as consent or agreement by or on behalf of Seller to any proposed action by Purchaser or any of its affiliates in a bankruptcy proceeding, including any proposed assumption, assumption and assignment or other disposition of this Agreement.

(d)           If the Payment Obligors, taken as a whole, cease to engage in the activities required to achieve Net Sales, then Purchaser shall, or shall cause a Payment Obligor to, send written notice thereof to Seller together with a detailed explanation for such cessation of activities.

SECTION 1.03.                    Net Sales Reporting.

(a)           Purchaser shall,  on behalf of itself and the other Payment Obligors to, (i) within 60 days following the date of the First Commercial Sale of a Product by or on behalf of any Payment Obligor in the Territory and within 60 days following the first day of each Calendar Year thereafter, provide to Seller an annual budget setting forth a good faith estimate of the estimated Net Sales of the Products for such Calendar Year, together with information and documentation reasonably supporting the calculations thereof if requested by Seller (for the avoidance of doubt, neither Purchaser nor any Payment Obligor shall be deemed to have made any representation, warranty or agreement with respect to any such budget or the amount of Net Sales that shall be achieved in such Calendar Year),  and (ii) within 60 days after the end of the Calendar Year in which the First Commercial Sale of a Product occurs and within 60 days after the end of each Calendar Year thereafter, deliver to Seller a report (each, a “Net Sales Report”) setting out, in reasonable detail, (A) the aggregate gross amount invoiced by Payment Obligors for the sale of Products, (B) Net Sales, (C) a description (including amounts) of all deductions used to calculate Net Sales and the calculation thereof (with amounts deducted from the aggregate gross amount invoiced set out by subclause of the definition of “Net Sales”), (D) the amount of the Milestone Payments due on such Net Sales (if any), in each case ((A), (B) and (C)), in each applicable country in the Territory during the applicable period (including such amounts expressed in local currency and as converted to United States dollars in accordance with Section 1.04).  The Net Sales Report for each Calendar Year also shall detail the amount, if any, of Services Fees and Out-of-Pocket Costs (each as defined in the Transition Services Agreement) actually reimbursed to Seller under the Transition Services Agreement in excess of the Aggregate Expense Amount (as defined in the Transition Services Agreement) that have not previously been deducted from Milestone Payments pursuant to Section 1.02(a) and the aggregate amount of such Services Fees and Out-of-Pocket Costs to be deducted from the Milestone Payment to be made for such Calendar Year (if any).

(b)           Purchaser shall, and shall cause the other Payment Obligors that are engaged in the sale of Products to, keep reasonable, correct and complete books and records pertaining to the sales of any Product (including with respect to Net Sales thereof throughout the Territory) to the extent required to calculate and verify Milestone Payments payable hereunder (“Net Sales Information”) and shall maintain the Net Sales Information until five years after the last day of the Calendar Year to which such Net Sales Information pertains.  Upon Seller’s request and subject to reasonable advance notice, Purchaser shall, and shall cause each of the other Payment Obligors engaged in the sale of any Product to, permit Seller or its Representatives to inspect their respective books and records relating to the Net Sales Reports during normal business hours in order to confirm the accuracy and completeness of the Net Sales Information and the amount of the Milestone Payments made hereunder.

(c)           Notwithstanding anything to the contrary in this Agreement, Seller shall have 60 days after receipt of a Net Sales Report pursuant to Section 1.03(a) to dispute any of the calculations therein by providing written notice thereof (including a reasonably detailed basis therefor) to Purchaser (such notice, an “Objection Notice”).  If Seller does not deliver an Objection Notice within such 60-day period, it shall be deemed to have irrevocably consented to the applicable Net Sales Report and the calculations therein.  If Seller timely delivers an Objection Notice the Parties shall work in good faith to resolve such dispute.  If the Parties are unable to resolve any such dispute within 30 days after Purchaser’s receipt of an Objection Notice, the matters remaining in dispute shall be submitted for resolution to a nationally recognized independent accounting firm to be mutually agreed upon by Seller and Purchaser (such agreed firm being the “Accountant”).  The Accountant’s determination shall be within the range of values proposed by Purchaser and Seller and the Accountant shall make such determination in accordance with this Agreement.  The decision of the Accountant shall be final and the costs of such Accountant shall be borne by the Parties in inverse proportion to the Parties’ success relative to their respective proposals and the Accountant’s final determination.  Not later than 30 days after such decision and in accordance with such decision, Purchaser shall pay the additional amounts due to Seller, with interest from the date originally due as provided in Section 1.04, or Seller shall reimburse the excess payments to Purchaser, as applicable.

(d)           All information disclosed pursuant to Section 1.03(b) or Section 1.03(c) shall be subject to the confidentiality and non-use provisions set forth in Section 5.03 and the Parties shall cause the Accountant, if any, to enter into a reasonably acceptable confidentiality agreement obligating such person to retain all financial information in confidence pursuant to such confidentiality agreement.

SECTION 1.04.                    Mode of Payment; Interest; Tax Treatment.  Purchaser shall pay to Seller the Milestone Payments by wire transfer of immediately available funds to such bank account or accounts as Seller may from time to time designate by advance written notice to Purchaser.  All payments to be made by Purchaser to Seller under this Agreement shall be made in United States dollars.  For purposes of calculating Net Sales for any Product sold in a currency other than United States dollars, the rate of exchange to be used in computing the currency equivalent in United States dollars due to Seller shall be a well-established and widely recognized rate of exchange used by Purchaser for reporting such sales for United States financial statement purposes, consistently applied.  If Purchaser fails to make any payment pursuant to this Agreement when due, any such late payment shall bear interest at a per annum rate equal to the lesser of (a) the U.S. Prime Rate, as reported in The Wall Street Journal, Eastern Edition, for the first date on which such payment was delinquent, plus two percent, and (b) the maximum interest rate permitted by applicable Law (with such rate being referred to herein as the “Default Rate”), beginning on the first date on which such payment was delinquent and ending on the date on which such payment is made, calculated based on the actual number of days such payment is overdue.  The Milestone Payments shall be treated as an adjustment to the Closing Payment for all Tax purposes, unless otherwise required by applicable Law and unless any portion of such Milestone Payment is required to be treated as interest in respect of deferred consideration for Tax purposes.

SECTION 1.05.                    Diligent Efforts. Commencing upon the Closing Date and ending on the payment to Seller of Milestone Payments in an amount equal to the Milestone Payment Cap, Purchaser shall, shall cause each Affiliated Payment Obligor to, and shall use its commercially reasonable efforts to cause each other Payment Obligor to (i) subject to the last sentence of this Section 1.05, use Diligent Efforts to Exploit the Compound and the Products in order to achieve Net Sales and (ii) except in a manner that is consistent with the normal business practices of Purchaser and the other Payment Obligors, as applicable, not act in a manner that intentionally reduces Net Sales, including by deferring or delaying the receipt or recognition of any sales of any Product in a manner that is inconsistent with the normal business practices of Purchaser and the other Payment Obligors, as applicable; provided, however, that, subject in all cases to Purchaser’s compliance with its obligations under clause (i) of this Section 1.05, (A) Purchaser shall have the right to pursue the Exploitation of the Products in such a manner as Purchaser shall determine in good faith to be in its best interests, and (B) following (but not prior to) the First Commercial Sale, Purchaser shall have the right to discontinue or delay the Development of the Compound and Products in the event that that Purchaser reasonably determines in good faith that, notwithstanding Purchaser’s use of such Diligent Efforts, further investment in Development of Products would not be reasonably likely to generate a positive return on investment on a risk-adjusted basis.  Notwithstanding the foregoing, prior to the First Commercial Sale, Purchaser shall not discontinue or delay the Development of the Compound and Products, including by failing to pay undisputed amounts due under the Transition Services Agreement (provided, that notwithstanding anything herein to the contrary, Purchaser may discontinue or delay such Development at any time if (x) directed to do so on the basis of human safety by any Governmental Entity or the data safety monitoring board for an Ongoing Trial, (y) the Company would not be able to distribute and sell in the United States the Product that is the subject of the Ongoing Trials without infringing any Third Party’s Intellectual Property in existence as of the time of such discontinuation or delay, or (z) [***].

SECTION 1.06.                    Transfer of Products; Change of Control of the Company.  Any Change of Control of the Company or any transfer, sale, license, conveyance or other disposition of all rights in the Compound, all rights in the Products or any other material rights (including Intellectual Property) related to the Compound or a Product by any Payment Obligor shall require that the purchaser of the Equity Interests or assets of the Company pursuant to such Change of Control or the transferee or assignee of such assets or rights, respectively, agree to be bound by the obligations with respect to the Milestone Payments set forth in this Article I and shall be a Payment Obligor for all purposes under this Agreement.  Purchaser shall remain primarily responsible for the payment of the Milestone Payments to Seller notwithstanding any such transfer, sale, license, conveyance or other disposition.

SECTION 1.07.                    Cash-Free; Debt-Free.  At or immediately prior to Closing, Seller shall cause the Company (i) to pay, or make arrangements for payment of, any and all Indebtedness and all payment obligations of the Company that are accrued or otherwise due and owing as of the Closing, and (ii) to distribute any remaining cash and cash equivalents, after payment of the amounts described in clause (i) of this Section 1.07, to Seller.

SECTION 1.08.                    Reversion Right.

(a)           Notwithstanding anything to the contrary contained in this Agreement, in the event that (i) Purchaser (or any person who becomes a Payment Obligor pursuant to Section 1.06) breaches any of its obligations set forth in Section 1.02(a) (or a breach of Section 4.06(a) with respect to a Milestone Payment), Section 1.05 (solely with respect breaches occurring prior to the First Commercial Sale) or Section 1.06, which breach remains uncured at (or is not capable of being cured by) 5:00 p.m., Eastern Time, on the forty-fifth (45th) day following written notice of such breach to Purchaser (or the applicable Payment Obligor) by Seller, or (ii) Purchaser (or any person who becomes a Payment Obligor pursuant to Section 1.06) discontinues the Exploitation of the Compound or any Product prior to the payment to Seller of Milestone Payments in an amount equal to the Milestone Payment Cap, upon written notice (the “Reversion Notice”) to Purchaser (or the applicable Payment Obligor) by Seller (which Reversion Notice may (or may not) be provided by Seller in its sole discretion), Purchaser (or the applicable Payment Obligor) shall, and shall cause its applicable affiliates (including the Company) (Purchaser, any such Payment Obligor and their respective affiliates that own or otherwise hold any rights, interests or assets to be conveyed in the Reversion, each, a “Reversion Seller”) to, as promptly as practicable (but in any event with ninety (90) days of the Reversion Notice), sell, convey, transfer, assign and deliver, without consideration other than Seller or its designated affiliates’ assumption of the Reversion Assumed Liabilities, to Seller or its designated affiliates’, free and clear of all Liens other than Permitted Liens, all of the Reversion Sellers’ right, title and interest in or to, as of the date of the Reversion Notice, all of the following (as elected by Seller) (collectively, the “Reversion Assets”): (A) all rights and assets assigned or contributed to the Company by Seller or any of its affiliates pursuant to this Agreement or any Ancillary Agreement, (B) all Drug Approval Applications and related regulatory and safety documents and data with respect to the Compound or any Product, (C) all inventories of Products, and (D) all rights and assets to the extent assignable (including Intellectual Property, Contracts and Permits) developed or acquired (including by license) by a Reversion Seller after the Closing Date that are used primarily for or that are used in and material to the Exploitation of the Compound or the Products (the “Reversion”).  For the avoidance of doubt, in no event shall the Reversion Assets include, or the Reversion result in the transfer of, any shares of capital stock of, or any other Equity Interest in, the Company to Seller or any of its affiliates.

(b)           In connection with the Reversion, (i) the Reversion Sellers shall, jointly and severally, make representations and warranties for the benefit of Seller or its designated affiliates materially consistent with the representations and warranties set forth in Section 3.01, Section 3.02 and represent and warrant that each of the applicable Reversion Sellers has good and valid title to the Reversion Assets owned by it, free and clear of any Liens other than any Permitted Liens or any license agreements entered into prior to the date of the Reversion Notice (and shall make no other representations and warranties in connection with the Reversion), which representations and warranties shall survive until the fifth anniversary of the closing of the Reversion; (ii) the Reversion Sellers shall be responsible, at their own cost and expense, for obtaining all Consents of Third Parties (including Governmental Entities) necessary for them to consummate the Reversion; (iii) the Reversion Sellers shall provide Seller or its designated affiliates a license materially consistent with the terms of Section 5.08; (iv) the Reversion Sellers shall grant to Seller or its designated affiliates a perpetual, assignable, sublicenseable, non-exclusive, worldwide, royalty-free license to all (A) Intellectual Property held by the Reversion Sellers used in connection with the Exploitation of the Compound or the Products to the extent

not assignable pursuant to Section 1.07(a) and (B) assets or rights that would be Reversion Assets but for the fact that such assets or rights are incapable of being transferred pursuant to applicable Law, in each case, for the Exploitation of the Compound or the Products; (v) Seller or its designated affiliates will assume all liabilities of the Reversion Sellers arising out of the Reversion Assets (but excluding any such liabilities arising out of any noncompliance with Law or any breach or violation of or failure to perform under any Reversion Asset by any Reversion Seller) (collectively, the “Reversion Assumed Liabilities”); (vi) the Reversion Sellers shall, jointly and severally, indemnify, defend and hold harmless the Seller Indemnitees from and against, and compensate and reimburse them for, any and all Losses incurred by such Seller Indemnitees arising out of or resulting from (A) any breach of any of their representations or warranties referenced in clause (i) above or any breach of any covenants made or undertaken in connection with the Reversion and (B) any liabilities of any Reversion Seller other than the Reversion Assumed Liabilities; (vi) if not already expired or terminated, each Ancillary Agreement shall automatically terminate upon the closing of the Reversion; and (vii) each Reversion Seller and Seller or its designated affiliates shall cooperate with one another and use its commercially reasonable efforts to take or cause to be taken in an expeditious manner all actions and to do or cause to be done all things necessary or appropriate to consummate the Reversion and the related transactions contemplated by this Section 1.08(b) as promptly as practicable.

(c)           Seller’s rights under this Section 1.08 shall not limit, diminish or otherwise impair in any respect any other rights or remedies to which Seller is entitled under this Agreement with respect to any breach by Purchaser (or any person who becomes a Payment Obligor pursuant to Section 1.06) of any of its obligations set forth in Section 1.02(a) (or a breach of Section 4.06(a) with respect to a Milestone Payment), Section 1.05 or Section 1.06; provided, however, that Seller shall not be entitled to exercise its right to cause a Reversion under this Section 1.08 and recover money damages or exercise any other rights for any such breach or termination.  If at the time Seller otherwise would be entitled to deliver a Reversion Notice, Purchaser or any Payment Obligor or their respective affiliates is engaged in a bona fide process that would result in the consummation of any transaction subject to Section 1.06 (“Sales Process”), the cure period described in the first sentence of Section 1.08(a)  shall not commence unless and until the termination of such Sales Process without the consummation of any such transaction has occurred.  Purchaser (or any person who becomes a Payment Obligor pursuant to Section 1.06) shall notify Seller in writing promptly upon any such termination of a Sales Process.  In the event any such Sales Process results in the consummation of any transaction subject to Section 1.06, any Reversion Notice automatically shall be deemed withdrawn and Seller shall be entitled to pursue any rights or remedies to which Seller is entitled under this Agreement.  The occurrence of a Sales Process shall not relieve or release Purchaser or any Payment Obligor of any obligations under this Agreement or any Ancillary Agreement.

SECTION 5.06.                    Publicity.  Other than the press release(s) to be agreed upon in writing by Purchaser and Seller and issued following the execution of this Agreement, neither of Purchaser, on the one hand, nor Seller, on the other hand, will issue or permit any of their respective affiliates to issue any press release, website posting or other public announcement with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), except as may be required by Law or stock exchange rules or regulations (in which case whichever of Purchaser or its affiliates or Seller or its affiliates, as applicable, are required to make the release or statement shall (i) consult with the other Party (whether or not such other Party is named in such release or statement), a reasonable time prior to its issuance to allow the other Party to comment on such release or statement in advance of such issuance, (ii) consider in good faith any comments timely provided by such other Party to such release or statement, and (iii) after such release or statement, provide the other Party with a copy thereof (or summary thereof in the case of oral statements)); provided, however, that Purchaser and its affiliates, on the one hand, and Seller and its affiliates, on the other hand, may, subject to the terms and conditions of this Agreement, make (x) internal announcements to their respective employees and communicate with Governmental Entities regarding this Agreement and the transactions contemplated hereby or by the Ancillary Agreements and (y) announcements and communications with customers, suppliers, distributors or other persons engaged in the Company Business regarding this Agreement and the transactions contemplated hereby or by the Ancillary Agreements, in the case of the preceding clause (y) to the extent such announcements or communications are consistent with the Parties’ prior public disclosures regarding the transactions contemplated by this Agreement.  If Purchaser or Seller or any of their affiliates, based on the advice of its counsel, determines that this Agreement, or any of the other Ancillary Agreements, must be publicly filed with a Governmental Entity, then such Party or its applicable affiliate, prior to making any such filing, shall provide the other Party and its counsel with a redacted version of this Agreement (and any other Ancillary Agreement) which it intends to file, and will consider in good faith any comments provided by such other Party or its counsel and use commercially reasonable efforts to ensure the confidential treatment by such Governmental Entity of those sections specified by such other Party or its counsel for redaction and confidentiality.  Notwithstanding any other provision of this Agreement, the requirements of this Section 5.06 shall not apply to any disclosure of Seller, the Company or Purchaser of any information concerning this Agreement or the transaction contemplated hereby in connection with any dispute between the Parties

SECTION 5.07.                    Resignations.  Seller shall cause each director and officer of the Company to resign in such capacity, such resignations to be effective as of the Closing.

SECTION 5.08.                    Use of Retained Names and Marks; Use of Trademarks by Seller During Transition Period.

(a)           Purchaser hereby acknowledges that Seller or its affiliates (other than the Company) owns all right, title and interest in and to the trademarks, service marks, domain names, logos and names set forth in Section 5.08 of the Seller Disclosure Schedule, together with all variations and acronyms thereof and all trademarks, service marks, domain names, logos, trade names, trade dress, company names and other identifiers of source or goodwill containing, incorporating, based on or associated with any of the foregoing (collectively, the “Retained Names and Marks”), and that, except as expressly provided below, any and all right of the Company to use the Retained Names and Marks shall terminate as of the Closing and to the extent any implied or express rights in any Trademark, Trademark application, or Trademark registration owned by Seller or its affiliates were conveyed to the Company, such rights shall immediately revert to Seller and its affiliates (other than the Company), along with any and all goodwill associated therewith.  Purchaser further acknowledges that it has no rights or interests, and is not acquiring any rights or interests, directly or indirectly, through the Company or otherwise, to use the Retained Names and Marks, except as expressly provided herein.

(b)           The Company, for a period of 45 days after the Closing Date, shall be entitled to use, solely in connection with the operation of the Company Business as operated immediately prior to the Closing, all of the Company’s existing stocks of product labeling, inserts and packaging in existence and used by the Company as of the Closing (collectively, the “Existing Stock”), in each case, containing the Retained Names and Marks, after which period Purchaser shall cause the removal or obliteration of all Retained Names and Marks from such Existing Stock or cease using such Existing Stock.  Upon Seller’s request, Purchaser shall, and shall cause the Company, as applicable, to promptly execute all assignment, transfer and other documents, and take all steps, in each case, that Seller believes are necessary or desirable to confirm, effectuate or otherwise evidence or record Seller’s and its affiliates’ (excluding, after the Closing, the Company) rights, title and interests in and to, and control over, the Retained Names and Marks, and Seller shall pay the associated reasonable out-of-pocket costs and expenses incurred by Purchaser.

(c)           Except as expressly provided in this Section 5.08, no right to use the Retained Names and Marks is granted by Seller or any of its affiliates to Purchaser or its affiliates (including, after the Closing, the Company), whether by implication or otherwise, and nothing hereunder permits Purchaser or its affiliates (including, after the Closing, the Company), to use the Retained Names and Marks in any manner, other than in connection with the Existing Stock as set forth in this Section 5.08, or to register or seek to register, or to permit, cause or assist any Third Party to register or to seek to register, any of the Retained Names and Marks in any jurisdiction.  Purchaser shall not, and shall cause its affiliates (including, after the Closing, the Company), not to, use the Retained Names and Marks in any manner that may damage or tarnish

the reputation of Seller or its affiliates (other than the Company) or the goodwill associated with the Retained Names and Marks.

(d)           Purchaser agrees that neither Seller nor any of its affiliates shall have any responsibility for claims by Third Parties to the extent arising out of, or relating to, the use by the Company of any of the Retained Names and Marks after the Closing.  In addition to any and all other available remedies, Purchaser shall defend, indemnify and hold harmless the Seller Indemnitees from and against, and compensate and reimburse them for, any and all such claims to the extent arising out of the use of the Retained Names and Marks (i) by the Company in accordance with the terms and conditions of this Section 5.08, other than such claims that the Retained Names and Marks infringe the Intellectual Property of any Third Party; or (ii) by Purchaser or any of its affiliates (including, after the Closing, the Company) in violation of or outside the scope permitted by this Section 5.08.  Notwithstanding anything in this Agreement to the contrary, Purchaser hereby acknowledges and agrees that in the event of any breach or threatened breach of this Section 5.08, Seller shall suffer irreparable harm, and Seller, in addition to any other remedies available to it, (A) shall be entitled to a preliminary injunction, temporary restraining order or other equivalent relief restraining Purchaser and any of its affiliates (including, after the Closing, the Company) from any such breach or threatened breach and (B) shall not be required to provide any bond or other security in connection with any such injunction, order or other relief.

SECTION 5.09.                    Contribution of Assets.  Subject to Section 5.10(d) and 5.10(g), effective as of immediately prior to the Closing, Seller, on behalf of itself and each of its affiliates, hereby contributes, assigns, transfers, conveys and delivers to the Company, all of Seller’s and such affiliates’ right, title and interest in and to all of the assets listed in Section 5.09 of the Seller Disclosure Schedule, in each case, free and clear of any Liens, other than Permitted Liens.

SECTION 5.10.                    Further Action.

(a)           On the terms and subject to the conditions of this Agreement (including Section 5.04), each Party shall use its commercially reasonable efforts (except to the extent a higher standard is provided for herein, in which case, the applicable Party shall use efforts that meet such higher standard) to take or cause to be taken in an expeditious manner all actions and to do or cause to be done all things necessary or appropriate to satisfy the conditions to the Closing, to consummate the Acquisition and the transactions contemplated by this Agreement and the Ancillary Agreements and to comply promptly with all legal requirements that may be imposed on it or any of its affiliates with respect to the Closing.  Notwithstanding the foregoing or any other provision of this Agreement, none of Seller, Purchaser or their respective affiliates shall be required to pay or commit to pay any amount to (or incur any obligation in favor of) any person from whom any Consent or waiver may be required in order for the Closing to occur, except as may be expressly required under the terms of the applicable Contract or Law (which will be paid by Seller).  In addition to the foregoing, Purchaser agrees, subject to any applicable obligations of confidentiality, to provide such evidence as to its financial capability, resources and creditworthiness as may be reasonably requested by any Third Party whose Consent is sought hereunder.  Subject to mutually agreed upon confidentiality protections, each of the Parties will

32

cooperate with and furnish to the other Party such necessary information and reasonable assistance as such other Party may reasonably request in connection with the foregoing.

(b)           On or prior the Closing Date, Seller shall prepare, execute and, if required under applicable Law, have notarized (or, as applicable, cause its affiliates to prepare, execute and, if required under applicable Law, have notarized) assignments required to transfer to the Company any Registered IP (other than Trademarks and domain name registrations) and other Owned Intellectual Property (other than Trademarks and domain names).  Within sixty (60) days after the Closing Date, Seller shall grant to the Company, effective as of the Closing Date, perpetual, assignable, sublicenseable, non-exclusive, worldwide, royalty-free licenses in any other Company Intellectual Property as may be reasonably necessary for or related to the Exploitation of the Products and the conduct of the Company Business.  Within sixty (60) days after the Closing Date, Seller shall prepare, execute and, if required under applicable Law, have notarized (or, as applicable, cause its affiliates to prepare, execute and, if required under applicable Law, have notarized) assignments required to transfer to the Company any Trademarks constituting Registered IP.  Within sixty (60) days after the Closing Date, Seller shall grant to the Company, and shall cause its applicable affiliate to grant to the Company, effective as of the Closing Date, a perpetual, assignable (but solely in connection with any assignment subject to Section 1.06), sublicenseable (but solely in connection with the conduct of the Company Business or the Exploitation of any Product), exclusive, worldwide, royalty-free license to use any Trademarks constituting Registered IP that are not transferred to the Company at or prior to the Closing, provided that such license shall automatically terminate and be of no further force or effect upon the assignment of the applicable Trademark to the Company in accordance with this Section 5.10(b).  As between Seller and its affiliates (excluding, after the Closing, the Company), on the one hand, and Purchaser and its affiliates (including, after the Closing, the Company), Seller or its applicable affiliate shall be responsible for filing such Intellectual Property assignments with applicable Governmental Entities.  Seller and its affiliates (including, after the Closing, the Company) shall pay all Third Party filing fees in connection with filing such assignments.

(c)           Notwithstanding the foregoing, to the extent that the Company or any of its affiliates reasonably believe, in good faith, that the transfer of any Registered IP set forth in Section 5.10(c) of the Seller Disclosure Schedule (the “Prohibited Registered IP”) to the Company on or prior to the Closing could jeopardize the validity of such Prohibited Registered IP or to the extent that applicable Law in any jurisdiction (each, a “Prohibited Jurisdiction”) prohibits the transfer of any Prohibited Registered IP to the Company on or prior to the Closing, Seller shall, or shall cause its affiliate that owns the Prohibited Registered IP as of the Closing Date (“Prohibited Registered IP Owner”) to, transfer to the Company, under the provisions of Section 5.10(a) and Section 5.10(b) above, any Prohibited Registered IP at such time as such transfer would not jeopardize the validity of such Prohibited Registered IP or is no longer prohibited by applicable Law in the applicable Prohibited Jurisdictions.  Within sixty (60) days after the Closing Date, Seller shall cause the Prohibited Registered IP Owner to grant to the Company, effective as of the Closing Date, a perpetual, assignable (but solely in connection with any assignment subject to Section 1.06), sublicenseable (but solely in connection with the conduct of the Company Business or the Exploitation of any Product), exclusive, royalty-free license to use the Prohibited Registered IP in the applicable Prohibited Jurisdictions.  Such license shall automatically terminate and be of no further force or effect upon the assignment of

33

the applicable Prohibited Registered IP to the Company in accordance with this Section 5.10.  With respect to any Prohibited Jurisdictions in which use of the Prohibited Registered IP must be established before such transfer may occur, Purchaser shall (i) provide written notification to Seller promptly upon commencement of the Company’s use of the Prohibited Registered IP in each Prohibited Jurisdiction; and (ii) provide Seller such information and specimens, and execute such documents, as may be necessary or appropriate to enable Seller to establish such use with the applicable Governmental Entity.

(d)           For the duration of the license contemplated by this Section 5.10 and until the Prohibited Registered IP is transferred to the Company, all goodwill generated by the Company’s use of the Prohibited Registered IP shall inure to the benefit of the Company.  To preserve the inherent value of the Prohibited Registered IP, Purchaser agrees that it shall, and shall cause the Company to, maintain the quality of the Company Business with respect to which the Prohibited Registered IP is used at a level commensurate with the standards prevailing in the industry applicable to comparable companies.

(e)           Purchaser agrees that neither Seller nor any of its affiliates shall have any responsibility:  (i) to pursue or prevent any infringement of the Prohibited Registered IP by any Third Party; or (ii) except in the event of a breach of any representation or warranty under Article III, for claims by Third Parties arising out of, or relating to, the use by Purchaser or any of its affiliates (including, after the Closing, the Company) of the Prohibited Registered IP.  In addition to any and all other available remedies, and except in the event of a breach of any representation or warranty under Article III, Purchaser shall defend, indemnify and hold harmless the Seller Indemnitees from and against, and compensate and reimburse them for, any and all such claims that may arise out of the use of the Prohibited Registered IP by Purchaser or any of its affiliates (including, after the Closing, the Company).

(f)            Within 60 days after the Closing Date, Seller shall, at Seller’s expense, take such action as may be reasonably necessary to effect the transfer of the domain names listed in Section 5.10(f) of the Seller Disclosure Schedule (the “Specified Domain Names”), to the Company including releasing any “lock” placed on the Specified Domain Names, obtaining the authorization code and providing that code to the Company, confirming the requested transfer upon receipt of a request to do so from the registrar used by the Company for the Specified Domain Names, and executing and delivering all authorizations reasonably necessary to effectuate electronic transfer of the Specified Domain Names.  Seller shall bear all costs charged by any transferring registrar, if any, in connection with the transfer of the Specified Domain Names to Company.

(g)           Notwithstanding the foregoing, with respect to the assets listed on Section 5.10(g) of the Seller Disclosure Schedule (the “TSA Assets”), Seller shall, or shall cause its affiliate that owns the applicable TSA Asset as of the Closing Date (“TSA Asset Owner”) to retain such TSA Asset until such time as such TSA Asset is no longer required to perform any remaining obligations under the Transition Services Agreement, at which time Seller or the TSA Asset Owner shall transfer to the Company, under the provisions of Section 5.10(b), any TSA Asset.  Within sixty (60) days after the Closing Date, Seller shall cause the TSA Asset Owner to grant to the Company, effective as of the Closing Date, a perpetual, assignable (but solely in connection

34

with any assignment subject to Section 1.06), sublicenseable (but solely in connection with the conduct of the Company Business), non-exclusive, worldwide, royalty-free license to use the TSA Asset.  Such license shall automatically terminate and be of no further force or effect upon the assignment of the applicable TSA Asset to the Company in accordance with this Section 5.10.  Until the TSA Assets are transferred to the Company, all goodwill, data, Intellectual Property and other assets generated by Seller’s or the Company’s use of the TSA Asset shall inure to the benefit of and be solely owned by the Company and shall be promptly transferred to the Company upon the creation thereof (unless such goodwill, data, Intellectual Property and other asset is itself a TSA Asset, in which case it shall be transferred to the Company in accordance with and at the time specified by this Section 5.10(g)).

SECTION 5.11.                    Supplemental Disclosure.  Seller may, prior to the Closing Date, deliver to Purchaser modifications, changes or updates to the Seller Disclosure Schedule in order to disclose or take into account facts, matters or circumstances which arise or occur during the Pre-Closing Period.  No updated information provided to Purchaser in accordance with this Section 5.10(g) shall be deemed to cure any breach of representation, warranty or covenant made in this Agreement, except for breaches of the representation and warranties which would have resulted but for such modifications, changes or updates in the Seller Disclosure Schedule where the underlying matter disclosed arises after the date of this Agreement and is contemplated by this Agreement, in which case such breach will be deemed to be cured and will not be indemnifiable under Article VIII.  No such updated information shall be taken into account in determining whether the condition set forth in Section 6.02(a) has been satisfied.

SECTION 5.12.                    Insurance.  The coverage under all insurance policies related to the Company and arranged or maintained by Seller or any of its affiliates is only for the benefit of Seller and such affiliates, and not after the Closing for the benefit of Purchaser, the Company or their respective affiliates.  As of the Closing Date, Purchaser agrees to arrange for its own insurance policies with respect to the Company covering all periods after the Closing and agrees not to seek (and to cause its affiliates, including the Company, not to seek), through any means, to benefit from Seller’s or its affiliates’ insurance policies which may provide coverage for claims relating in any way to the Company and arising after the Closing.

SECTION 5.13.                    Indemnification.

(a)           Purchaser and Seller agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Closing, whether asserted or claimed prior to, at or after the Closing, now existing in favor of the current or former directors or officers of the Company (the “Company Indemnitees”) as provided in the organizational documents of the Company or in any agreement with the Company as in effect on the date of this Agreement shall survive the Closing and shall continue in full force and effect.

(b)           Purchaser shall cause the Company to maintain in effect any and all exculpation, indemnification and advancement of expenses provisions currently existing in the organizational documents of the Company or in any indemnification agreements of the Company with any of the Company Indemnitees, in each case in effect as of the date of this Agreement, for acts or omissions occurring at or prior to the Closing.

35

(c)           In the event the Company or any of its successors or assigns (i) consolidates with or merges into any other person (or engages in any similar transaction) and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in either such case, proper provision shall be made so that the successors and assigns of the Company shall assume all of the obligations set forth in this Section 5.13.  The provisions of this Section 5.13 are intended for the benefit of, and shall be enforceable by, the Company Indemnitees and their respective heirs and representatives.  The rights of all Company Indemnitees under this Section 5.13 are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by Contract, applicable Law or otherwise.

(d)           During the period ending six (6) years after the Closing Date, at Seller’s sole expense, Seller shall maintain in effect its current directors’ and officers’ liability insurance covering acts or omissions of the Company’s officers and directors occurring at or prior to the Closing Date on terms with respect to such coverage, and in amount, not less favorable to such persons than those of such policy in effect on the date hereof (or Seller may substitute therefor policies, issued by reputable insurers, of at least the same coverage with respect to matters occurring prior to the Closing Date).

SECTION 5.14.                    Seller Retained Materials.  Notwithstanding anything to the contrary contained in this Agreement, Purchaser acknowledges and agrees that all of the following shall remain the property of Seller, and neither Purchaser nor any of its affiliates (including, after the Closing, the Company) shall have any interest therein: (a) all records and reports prepared or received by Seller, any of its affiliates or Representatives solely relating to the sale of the Company and the transactions contemplated hereby or by the Ancillary Agreements, including all analyses relating to the Company or Purchaser or its affiliates so prepared or received, and (b) all confidentiality agreements with prospective purchasers of the Company or any portion thereof, and all bids, expressions of interest and related materials received from Third Parties, in each case, with respect to the sale of the Company (“Sale Confidentiality Agreements”).  In addition, Seller shall have the right to retain copies of the documents, materials and data relating to the Company and the conduct of the Company Business prior to the Closing Date, all of which shall become subject to the terms of the Confidentiality Agreement pursuant to Section 5.03.  In the event that Purchaser reasonably believes that any Sale Confidentiality Agreement above has been breached, Purchaser may provide Seller with written notice of such suspected breach, which notice shall include a reasonable description of why Purchaser believes such a breach has occurred, including the identity, if reasonably ascertainable, of the person that Purchaser reasonably believes disclosed or otherwise used confidential information regarding the Compound or Company Business (the “Disclosing Third Party”).  Promptly following its receipt of any such notice, Seller shall inform Purchaser whether it or any of its affiliates entered into a Sale Confidentiality Agreement with the Disclosing Third Party with respect to the sale of the Company.  If Seller did enter into a Sale Confidentiality Agreement with the Disclosing Third Party, Seller shall, at the reasonable direction and sole cost and expense of Purchaser, enforce its rights under such Sale Confidentiality Agreement with respect to such suspected breach, provided, that Seller shall not have any obligation to commence a Proceeding against such Disclosing Third Party.  In the event Purchaser reasonably directs Seller to commence a Proceeding against such Disclosing Third

36

Party and Seller elects not to commence such a Proceeding, Seller shall cooperate with Purchaser to provide Purchaser with all of the rights necessary to commence such Proceeding and enforce the Sale Confidentiality Agreement against the Disclosing Third Party.  Purchaser shall not have the right to settle any such Proceeding or resolve any claims therein, in either case, if such settlement or resolution would adversely affect any rights of Seller or any of its affiliates under any such Sale Confidentiality Agreement in a respect that is unrelated to the Compound or the Company Business.  Purchaser shall reimburse Seller for its reasonable out-of-pocket fees and expenses incurred by it in connection with the enforcement of Seller’s rights under such Sale Confidentiality Agreement with respect to such suspected breach to the extent requested or otherwise approved by Purchaser.

SECTION 5.15.                    Solvency After Closing.  After the Closing, Purchaser agrees that it shall not, and that it shall cause its affiliates (including the Company) not to, take or fail to take any action that could result in a determination pursuant to applicable Law that, after giving effect to the transactions contemplated by this Agreement (or after giving effect to such transactions and to such other subsequent actions or omissions), Purchaser or any of its affiliates (including the Company) (a) was insolvent at the time of the Closing, (b) became insolvent as a result of the transactions contemplated by this Agreement, (c) was left with unreasonably small capital with which to engage in its business or (d) incurred debts beyond its ability to pay such debts as they mature, such that the payment of the Closing Payment or the Milestone Payments may be deemed a “fraudulent conveyance” or impermissible dividend or distribution under applicable Law or otherwise subject to claims of any creditors of Purchaser or any of its affiliates (including the Company) or their respective trustees in bankruptcy proceedings.

SECTION 5.16.                    Non-Competition.

(a)           Other than in connection with the performance of Seller’s obligations under the Ancillary Agreements, during the period that commences on the Closing Date and ends on the earlier of (i) the [***] anniversary of the Closing Date and (ii) the [***] anniversary of the date on which the first New Drug Application is approved with respect to a Product, Seller shall not, and shall not permit any of its affiliates (including the Company) to, directly or indirectly: (A) engage in or assist any other person in engaging in (including through the grant of a license or other right) the Restricted Business anywhere in the Territory or (B) have an ownership interest in any person that engages in the Restricted Business in the Territory.  Notwithstanding the foregoing, Seller or any of its affiliates may own, directly or indirectly, securities of any person engaged in the Restricted Business if (i) Seller or its affiliate is not a controlling person of, or a member of a group (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934) which controls such person and (ii) Seller and its affiliates collectively do not, directly or indirectly, own more than five percent (5%) of any class of securities of such person.

(b)           During the period that commences on the Closing Date and ends on the earlier of (i) the date on which Seller has been paid Milestone Payments in an amount equal to the Milestone Payment Cap and (ii) the date on which all Payment Obligors cease engaging in activities required to achieve Net Sales, Purchaser shall not, and shall not permit the Company or any of its Affiliated Payment Obligors to, directly or indirectly: (A) engage in or assist any other person in engaging in (including through the grant of a license or other right) the Restricted

Business anywhere in the Territory; or (B) have an ownership interest in any person that engages in the Restricted Business in the Territory.  Notwithstanding the foregoing, Purchaser may own, directly or indirectly, securities of any person engaged in the Restricted Business if (i) Purchaser or its affiliate is not a controlling person of, or a member of a group (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934) which controls such person and (ii) Purchaser and its affiliates collectively do not, directly or indirectly, own more than five percent (5%) of any class of securities of such person.

SECTION 5.17.                    Privileged Matters.

(a)           Each of the Parties acknowledges and agrees that each of Covington & Burling LLP (“Covington”) and Squire Patton Boggs (US) LLP (“Squire”) has acted as counsel to Seller and its affiliates in connection with the negotiation of this Agreement and any consummation of the transactions contemplated by this Agreement and the Ancillary Agreements.  In that capacity, each of Covington and Squire has engaged or may engage in communications with (i) other counsel to Seller (including internal counsel), (ii) Seller, (iii) the Company, and (iv) advisors and consultants to any of the foregoing that relate to the negotiation, documentation or consummation of the transactions contemplated by this Agreement and the Ancillary Agreements (“Deal Communications”).

(b)           In connection with the foregoing, Purchaser consents and agrees to Covington and Squire representing Seller and its affiliates after the Closing, including with respect to disputes in which the interests of Seller and its affiliates may be directly adverse to the interests of Purchaser and its affiliates, and even though Covington and Squire may have represented the Company in a matter substantially related to any such dispute, or may be handling ongoing matters for Seller and its affiliates.  Purchaser further consents and agrees to the use by Covington, Squire and Seller and its affiliates in connection with any such representation of any information known or obtained in connection with the representations described in Section 5.17(a).

(c)           In connection with the representation of Seller or one or more of its affiliates consistent with the foregoing, Purchaser irrevocably waives any conflict of interest arising from or in connection with (i) Covington’s and Squire’s prior representation of the Company and (ii) Covington’s and Squire’s representation of Seller and its affiliates prior to and after the Closing.

(d)           Subject to Section 5.17(e), Purchaser, on the one hand, and Seller, on the other hand, acknowledge and agree that the information relating to or arising out of the legal advice or services that have been or will be provided prior to the Closing Date for the benefit of both (i) Seller and its affiliates (other than the Company) and (ii) the Company, shall be subject to a shared privilege between Seller and such affiliates (other than the Company), on the one hand, and the Company, on the other hand, and, subject to the immediately following sentence, Seller and such affiliates and the Company shall have equal right to assert all such shared privileges in connection with privileged information under any Law and no such shared privilege may be waived after the Closing by (A) Seller or its affiliates without the prior written consent of Purchaser or the Company or (B) by the Company, Purchaser or any of their respective affiliates without the prior written consent of Seller.

(e)           Purchaser acknowledges and agrees, on its own behalf and on behalf of its directors, stockholders, members, partners, officers, employees and affiliates, that all Deal Communications shall be deemed to be retained, owned and controlled collectively by Seller and shall not pass to or be claimed by Purchaser or, following the Closing, the Company, even if such Deal Communications are in the Company’s possession.  All Deal Communications that are subject to the attorney-client privilege or the attorney work product privilege shall remain privileged after the Closing (the “Privileged Deal Communications”), with the privilege belonging solely to Seller and not Purchaser.

(f)            In the event that a dispute arises between Purchaser or Company and a Third Party, Purchaser and Company shall, at Seller’s sole cost and expense, assert the attorney-client privilege to prevent the disclosure of Privileged Deal Communications to such Third Party.  In the event that Purchaser is asked by any Third Party, for example in connection with a Proceeding, to access or obtain any of the Privileged Deal Communications, Purchaser shall immediately (and, in any event, within three Business Days) notify Seller in writing (including by making specific reference to this Section 5.17(f)).  Purchaser further agrees to use commercially reasonable efforts to assist Seller, at Seller’s sole cost and expense, in connection with any attempt to prevent the disclosure of any Privileged Deal Communications to a Third Party.

(g)           Prior to the Closing, Seller, the Company, Company Subsidiary or any of their respective affiliates or Representatives shall take action to remove from the premises of the Company (or any offsite back-up or other facilities) any Deal Communications, including by segregating, copying, deleting, erasing, exporting or otherwise taking possession of any Deal Communications.

SECTION 5.18.                    Exclusive Dealing.

(a)           During the Pre-Closing Period, neither Seller nor the Company shall, nor shall either of them authorize or permit any of its Representatives to, directly or indirectly, (i) take any action to solicit, initiate, or knowingly facilitate or encourage, the submission of any Acquisition Proposal, (ii) engage in any discussions or negotiations with any Third Party regarding an Acquisition Proposal or enter into any Contract with respect to an Acquisition Proposal, (iii) furnish or cause to be furnished, to any person, any information concerning the business, operations, properties or assets of the Company in connection with an Acquisition Proposal, or (iv) otherwise cooperate in any way with, or knowingly assist or participate in, or knowingly facilitate or encourage, any effort or attempt by any other person to do or seek any of the foregoing.  For purpose of this Agreement, “Acquisition Proposal” means, other than the transactions contemplated by this Agreement, any offer or proposal by a Third Party relating to any acquisition or purchase, direct or indirect, whether by way of asset purchase, equity purchase, merger, consolidation, share exchange, business combination or otherwise, of a material portion of the assets of the Company, or any Equity Interest in the Company, or any other transaction the consummation of which would reasonably be expected to frustrate the purposes of, impede, prevent or materially delay the transactions contemplated by this Agreement.

(b)           The Company shall immediately cease and cause to be terminated any existing discussions or negotiations with any persons (other than Purchaser and its affiliates and Representatives) conducted heretofore with respect to any Acquisition Proposal, other than to inform such persons of this Agreement.  Each of Seller and the Company agrees not to release, or permit to be released, any Third Party from the confidentiality provisions of any agreement which was entered into in connection with the consideration of an Acquisition Proposal.

SECTION 5.19.                    Right of Negotiation.  In the event that Purchaser or any of its affiliates (including, following the Closing, the Company) desires to grant to one or more Third Parties rights to Exploit (including rights to distribute) any Product in one or more of Japan, the People’s Republic of China, the Republic of Korea, or the Republic of China (Taiwan) (each, a “Subject Territory”), then Purchaser shall provide Seller with written notice (a “Third Party Offer Notice”) that Purchaser is soliciting offers from Third Parties for such rights.  Neither Purchaser nor any of its affiliates (including the Company) shall enter into any agreement with respect to such rights with any Third Party until 30 days (or such longer period as the Parties may agree) after delivery of the Third Party Offer Notice to Seller.  If, within such 30 day (or such longer) period, Seller or any of its affiliates delivers to Purchaser a good faith, bona fide, written offer proposing financial and other terms for such rights, then Purchaser shall negotiate such offer with Seller exclusively and in good faith for a period of 45 days (or such longer period as the Parties may agree) (the “Negotiation Period”) and Purchaser shall not discuss or enter into any agreement with respect to such rights with any Third Party during the Negotiation Period.  Notwithstanding the foregoing, Seller shall not have a right of negotiation under this Section 5.19 with respect to any bona fide grant by Purchaser or any of its affiliates (including, following the Closing, the Company) to a Third Party of rights to Exploit (including rights to distribute) any Product in a Subject Territory and any one or more of the following: (i) the United States, (ii) the United Kingdom, (iii) Germany, (iv) France, (v) Spain, (vi) Italy, or (vii) Australia together with two or more of Argentina, Mexico and Brazil.

SECTION 5.21.                    Closing Payment Funds.   During the Pre-Closing Period, Purchaser shall at all times maintain cash on hand that is sufficient to enable it to pay the Closing Payment to Seller and consummate the Acquisition and the other transactions contemplated by this Agreement to be consummated at the Closing.

such termination and (ii) that no such termination shall relieve a Party from any liability arising out of any breach of this Agreement by such Party of any representation or warranty of such Party contained herein or any covenant or agreement of such Party contained herein prior to such termination.

ARTICLE VIII

INDEMNIFICATION; SURVIVAL

SECTION 8.01.                    Indemnification by Seller.  Subject to this Article VIII and Section 10.06, from and after the Closing, Seller shall indemnify Purchaser and its affiliates and each of their respective officers and directors (the “Purchaser Indemnitees”) from and against, and compensate and reimburse them for, any and all losses, damages, fines, penalties and amounts paid in settlement, and reasonable Third Party costs and expenses incurred in connection therewith, including reasonable Third Party legal fees and expenses in connection with any Proceeding (collectively, “Losses”), incurred by such Purchaser Indemnitees, to the extent arising out of or resulting from any of the following:

(a)           any breach of any representation or warranty of Seller or any Seller affiliate contained in this Agreement or in any Ancillary Agreement other than the Note and the Security Agreement (solely to the extent such Ancillary Agreement does not include indemnification provisions that cover such breach) (disregarding for purposes of calculating Losses pursuant to this Article VIII any “material”, “in all material respects” or similar materiality qualification contained in any representation and warranty);

(b)           any breach of any covenant or agreement of Seller or any Seller affiliate contained in this Agreement or any Ancillary Agreement other than the Note and the Security Agreement (solely to the extent such Ancillary Agreement does not include indemnification provisions that cover such breach);

45

of Seller or any of its affiliates (including the Company), in either case, with respect to the Compound or Products or (ii) any claim by or on behalf of any Third Party with respect to any Ongoing Trial or any other clinical trial conducted by or on behalf of Seller or any of its affiliates (including the Company) with respect to the Compound or Products for personal injury, death or property damage arising out of such Ongoing Trial or other clinical trial, in each case ((i) and (ii)), to the extent relating to circumstances or events that arose or occurred prior to the Closing Date.

SECTION 8.02.                    Indemnification by Purchaser.  Subject to this Article VIII and Section 10.06, from and after the Closing, Purchaser shall indemnify Seller and its respective affiliates and each of their respective officers and directors (the “Seller Indemnitees”) from and against any and all Losses incurred by such Seller Indemnitees, to the extent arising out of or resulting from any of the following:

(a)           any breach of any representation or warranty of Purchaser contained in this Agreement or any Ancillary Agreement other than the Note and the Security Agreement (solely to the extent such Ancillary Agreement does not include indemnification provisions that cover such breach) (disregarding for purposes of calculating Losses pursuant to this Article VIII any “material”, “in all material respects” or similar materiality qualification contained in any representation and warranty);

(b)           any breach of any covenant of Purchaser contained in this Agreement or any Ancillary Agreement other than the Note and the Security Agreement (solely to the extent such Ancillary Agreement does not include indemnification provisions that cover such breach); and

(c)           any actions taken or omissions with respect to the Company or the Company Business by Purchaser or any of its affiliates, in each case, after the Closing (but excluding any Losses of a type for which any Purchaser Indemnitee is indemnified pursuant to Section 8.01 or under any Ancillary Agreement,  even if the amount of such Losses exceeds the amount of indemnification available under Section 8.01 or any such Ancillary Agreement).

SECTION 8.03.                    Indemnification Procedures.

(a)           Third Party Claims.  If any Purchaser Indemnitee or Seller Indemnitee (the “Indemnified Party”) receives written notice of the commencement of any Proceeding or the assertion of any claim by a Third Party or the imposition of any penalty or assessment (in each case other than with respect to Taxes, for which Section 9.03 and Section 9.04 apply) for which indemnity may be sought under Section 8.01 or Section 8.02 (a “Third Party Claim”), and such Indemnified Party intends to seek indemnity pursuant to this Article VIII, the Indemnified Party shall promptly (but no later than 30 days after receiving such notice) provide the other Party (the “Indemnifying Party”) with written notice of such Third Party Claim, stating the nature, basis, the amount thereof (to the extent known or estimated, which amount shall not be conclusive of the final amount of such Third Party Claim), the method of computation thereof (to the extent known or estimated), any other remedy sought thereunder, any relevant time constraints relating thereto, and, to the extent practicable, any other material details pertaining thereto, along with copies of the relevant documents evidencing such Third Party Claim and the basis for indemnification sought.  Failure of the Indemnified Party to give such notice within such 30 day

[***] = Portions of this exhibit have been omitted and filed separately with the Securities and Exchange Commission.  Confidential treatment requested under 17 C.F.R. Sections 200.80(b)(4) and  230.406.

46

period will not relieve the Indemnifying Party from its indemnification obligations hereunder, except to the extent that the Indemnifying Party is actually prejudiced thereby.  The Indemnifying Party will have 15 days from receipt of any such notice of a Third Party Claim to give notice to the Indemnified Party whether, with respect to a Third Party Claim (or portion thereof to the extent such Third Party Claim included multiple claims and such claims may be separately defended) it is assuming and controlling the defense, appeal or settlement proceedings thereof with counsel of the Indemnifying Party’s choice.  If the Indemnifying Party assumes the defense of a Third Party Claim (or portion thereof), it will be conclusively established for purposes of this Agreement that the claims made in that Third Party Claim with respect to which the Indemnifying Party has assumed the defense (except any such claims that are assumed by the Indemnifying Party solely because such claims cannot reasonably be separated from the claims that the Indemnifying Party proposes to assume) are within the scope of and subject to indemnification (provided, that the Indemnifying Party’s assumption of the defense of a Third Party Claim shall not conclusively establish the amount of any Losses from such Third Party Claims that are within the scope of and subject to indemnification hereunder).  The foregoing notwithstanding, the Indemnifying Party shall not be entitled to control the defense of any Third Party Claim if (i) in the case of any claim for indemnification by a Purchaser Indemnitee, such claim is with respect to a Proceeding (A) that, if determined in a manner adverse to such Purchaser Indemnitee, would reasonably be expected to adversely impact (including the withdrawal or suspension or likelihood of approval by the applicable Governmental Entity of) any Drug Approval Application with respect to the Compound or any Product, (B) regarding material Company Intellectual Property, (C) regarding ownership of the Company, the Shares or any asset(s) of the Company that are material (either individually or in the aggregate), or (D) that, if determined in a manner adverse to such Purchaser Indemnitee, would prohibit Purchaser from engaging in the Company Business, (ii) the applicable Indemnified Party has been advised by outside legal counsel that a material conflict of interest exists between the Indemnifying Parties and such Indemnified Party with respect to such Third Party Claim, (iii) the Indemnifying Party has failed to deliver timely notice that it is assuming the defense of such Third Party Claim or is failing to adequately prosecute or defend such Third Party Claim, or (iv) such Third Party Claim seeks an injunction or other equitable relief against such Indemnified Party.  So long as the Indemnifying Party has assumed or controls the defense, appeal or settlement proceedings of the Third Party Claim in accordance herewith, (A) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in (but not control) the defense, appeal or settlement proceedings of the Third Party Claim, (B) the Indemnified Party will not admit any liability, file any papers or consent to the entry of any judgment or enter into any settlement agreement, compromise or discharge with respect to the Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed, and (C) the Indemnifying Party will not admit to any wrongdoing by the Indemnified Party.  The Indemnifying Party shall not have the right to settle any Third Party Claim (including any Third Party Claim for which the amount payable in settlement exceeds the Cap) without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, unless such settlement, compromise or consent (I) includes an unconditional release of the Indemnified Party from all liability arising out of such claim, (II) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnified Party, (III) does not require the payment of any amount in excess of the Cap, and (IV) does not contain any equitable order, judgment or term which in any

[***] = Portions of this exhibit have been omitted and filed separately with the Securities and Exchange Commission.  Confidential treatment requested under 17 C.F.R. Sections 200.80(b)(4) and  230.406.

47

manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s affiliates.  As to any Third Party Claim with respect to which the Indemnifying Party does not elect to assume control of the defense, (i) any and all costs and expenses incurred by the Indemnified Party in connection with the defense, appeal or settlement of such Third Party Claim shall be deemed to be Losses recoverable by such Indemnified Party pursuant to this Article VIII, and (ii) the Indemnified Party will afford the Indemnifying Party an opportunity to participate in (but not control) such defense, at its cost and expense, and will consult with the Indemnifying Party prior to settling or otherwise disposing of any of the same. The Parties will act in good faith in responding to, defending against, settling or otherwise dealing with Third Party Claims.  The Parties will also cooperate in any such defense, appeal or settlement proceedings, and give each other reasonable access to all information relevant thereto; provided, that neither Party will be required to furnish any such information which would (in the reasonable judgment of such Party upon advice of counsel) be reasonably likely to (A) waive any privileges, including the attorney-client privilege, held by such Party or any of its affiliates or (B) breach any duty of confidentiality owed to any person (whether such duty arises contractually, statutorily or otherwise) or any Contract with any other person or violate any applicable Law (provided, that such Party shall use reasonable best efforts to obtain any required Consents and take such other reasonable action (such as the entry into a joint defense agreement or other arrangement to avoid loss of attorney-client privilege) to permit such access).  The Indemnified Party shall seek the consent (which shall not be unreasonably withheld, conditioned or delayed) of the Indemnifying Party prior to the settlement of any Third Party Claim or consent to the entry of any judgment with respect to a Third Party Claim; provided, however, that with respect to any settlement of a Third Party Claim entered into or any judgment of a Third Party Claim that was consented to without the Indemnifying Party’s prior written consent, such settlement or judgment shall not, in itself, be conclusive of the Indemnifying Party’s liability therefor, but, for the avoidance of doubt, shall not in any way limit an Indemnified Party’s right to make a claim with respect to the subject matter thereof in accordance with this Article IX.

(b)           Other Claims.

(i)            As soon as reasonably practicable after an Indemnified Party becomes aware of any claim that does not involve a Third Party Claim (and is not with respect to Taxes, for which Section 9.03 and Section 9.04 apply) that might result in Losses for which such Indemnified Party may be entitled to indemnification under this Article VIII (a “Direct Claim”), the Indemnified Party shall provide written notice (a “Claim Notice”) to the Indemnifying Party: stating the nature, basis, the amount thereof (to the extent known or estimated, which amount shall not be conclusive of the final amount of such Direct Claim), the method of computation thereof (to the extent known or estimated) and, to the extent practicable, any other material details pertaining thereto, along with copies of the relevant documents evidencing such Direct Claim and the basis for indemnification sought.  Failure of the Indemnified Party to give such Claim Notice will not relieve the Indemnifying Party from its indemnification obligations hereunder, except to the extent that the Indemnifying Party is actually prejudiced thereby.

(ii)           Following receipt of a Claim Notice from an Indemnified Party, the Parties shall have 30 days to make such investigation of the claim as the Parties reasonably deem necessary or desirable.  For the purposes of such investigation, each Party agrees to make

[***] = Portions of this exhibit have been omitted and filed separately with the Securities and Exchange Commission.  Confidential treatment requested under 17 C.F.R. Sections 200.80(b)(4) and  230.406.

48

available to the other Party or its Representatives such information relied upon by such other Party to substantiate the claim and all other information in its possession or under its control that the other Party reasonably requests.

(iii)          Within such 30-day period, an Indemnifying Party may object to any claim set forth in such Claim Notice by delivering written notice to the Indemnified Party of the Indemnifying Party’s objection (an “Indemnification Objection Notice”).  Such Indemnification Objection Notice must describe the grounds for such objection in reasonable detail.  If an Indemnification Objection Notice is not delivered by the Indemnifying Party to the Indemnified Party within 30 days after receipt by the Indemnifying Party of the Claim Notice (the “Indemnification Objection Period”), such failure to so object shall be an acknowledgment by the Indemnifying Party that the Indemnified Party is entitled to indemnification under Article VIII for the full amount of the Losses set forth in such Claim Notice.

(iv)          If an Indemnifying Party shall object in writing during the Indemnification Objection Period to any claim or claims by an Indemnified Party made in any Claim Notice, the Indemnifying Party and the Indemnified Party shall attempt in good faith for 20 days (or any mutually agreed upon extension thereof) thereafter to agree in writing upon the rights of the respective Parties with respect to each of such claims.  If no such written agreement can be reached after good faith negotiation, each of the Indemnifying Party and the Indemnified Party may take action to resolve the objection in accordance with Section 10.10, Section 10.11, Section 10.12 and Section 10.13.

SECTION 8.04.                    Limitations on Indemnification. Notwithstanding anything to the contrary contained in this Agreement, (x) except with respect to the Specified Representations and the representations and warranties set forth in Section 3.11, (a) Seller shall not have any liability under Section 8.01(a) unless the aggregate liability for Losses suffered by Purchaser Indemnitees thereunder exceeds $200,000 (the “Deductible”), and then only to the extent of such excess and (b) Seller’s aggregate maximum liability under Section 8.01(a) shall not exceed an amount equal to fifteen percent (15%) of the of the aggregate amount of Cash Payments that Purchaser has actually paid to Seller (the “Cap”) (it being understood that, so long as a Purchaser Indemnitee makes a claim for indemnification pursuant to Section 8.01(a) within the time proscribed pursuant to Section 8.08, the fact that the Losses recoverable in respect of such claim exceed such Cap as of a particular time shall not preclude such Purchaser Indemnitee from recovering such Losses to the extent such Cap increases by virtue of Purchaser making one or more Milestone Payments) and (y) (a) the aggregate maximum liability of Seller under Section 8.01(a) or Purchaser under Section 8.02(a), in each case, shall not exceed the aggregate amount of Cash Payments that Purchaser has actually paid to Seller, (b) subject to Section 8.09, neither Party shall have any liability for an otherwise indemnifiable Loss that is contingent unless and until such contingent Loss becomes an actual Loss of the Indemnified Party and is due and payable, so long as the claim for such Loss was timely submitted pursuant to the provisions of this Article VIII; (c) neither Party shall be liable for any Losses to the extent the Purchaser Indemnitees or the Seller Indemnitees, as applicable, failed to mitigate such Losses in accordance with applicable Laws (provided, that, for clarity, this clause (c) shall only relieve a Party to the extent of any Losses that would not have been incurred had such Purchaser Indemnitees or Seller Indemnitees, as applicable, mitigated in accordance with applicable Laws); (d) neither Party shall be liable for any Loss to the extent arising from (i) a change in accounting or taxation Law, policy or practice made after the Closing, other than a change required to comply with any Law, policy or practice in effect on the date of this Agreement, or (ii) any Law not in force on the date of the Closing or any change in Law which takes effect retroactively or occurs as a result of any increase in the rates of taxation

in force on the Closing Date;  (e) neither Party shall be liable for any otherwise indemnifiable Loss arising out of any breach of any representation, warranty, covenant or agreement of such Party unless a claim therefore is asserted in writing (as provided in Section 8.03) by the Indemnified Party timely in accordance with Section 8.08, failing which such claim shall be waived and extinguished; and (f) Seller’s aggregate maximum liability under Section 8.01 with respect to Excluded Losses recovered in a Third Party Claim shall not exceed an amount equal to the aggregate amount of Cash Payments that Purchaser has actually paid to Seller (the “Excluded Losses Cap”) (it being understood that, so long as a Purchaser Indemnitee makes a claim for indemnification pursuant to Section 8.01 within the time proscribed pursuant to Section 8.08, the fact that the Excluded Losses recoverable in respect of such Third Party Claim exceed the Excluded Losses Cap as of a particular time shall not preclude such Purchaser Indemnitee from recovering such Excluded Losses to the extent such Excluded Losses Cap increases by virtue of Purchaser making one or more Milestone Payments).

SECTION 8.05.                    Calculation of Indemnity Payments.

(a)           The amount of any Loss for which indemnification is provided under this Article VIII or Article IX shall be net of any amounts actually recovered by the Indemnified Party (including under insurance policies) with respect to such Loss.

(b)           If an Indemnified Party recovers an amount from a Third Party in respect of Losses that are the subject of indemnification hereunder after all or a portion of such Losses have been paid by an Indemnifying Party pursuant to this Article VIII, then the Indemnified Party shall promptly remit to the Indemnifying Party the excess (if any) of (i) (A) the amount paid by the Indemnifying Party in respect of such Losses plus (B) the amount received by the Indemnified Party in respect thereof over (ii) the full amount of the Losses (but not to exceed the amount paid by the Indemnifying Party in respect of such Losses).

(c)           Neither Party shall be entitled to any payment, adjustment or indemnification more than once with respect to the same matter.

SECTION 8.06.                    Remedies.  Except as expressly provided in this Agreement and for actual fraud, from and after the Closing, each Party’s sole and exclusive remedy with respect to any and all claims relating to or arising out of this Agreement, the Company, the Shares or the transactions contemplated by this Agreement shall be pursuant to the indemnification provisions set forth in this Article VIII or Article IX and the remedies in Section 10.13, in each case, except for such remedies as may be available under the provisions of the Ancillary Agreements.  In furtherance of the foregoing, each Party hereby waives, from and after the Closing, any and all rights, claims and causes of action relating to or arising out of this Agreement, the Company, the Shares or the transactions contemplated by this Agreement, whether based on warranty, in contract, in tort (including negligence or strict liability) or otherwise, that such Party or any other Purchaser Indemnitee or Seller Indemnitee may have against the other Party, any of its affiliates or any other person, arising under or based upon any Law, except (i) pursuant to the indemnification provisions set forth in this Agreement, including in Article VIII or Article IX, and the remedies in Section 10.13, and (ii) claims and causes of action relating to actual fraud.

SECTION 8.07.                    Tax Treatment of Indemnification.  For all Tax purposes, Purchaser and Seller agree to treat any indemnity payment under this Agreement as an adjustment to the Cash Payments unless a final determination of a Taxing Authority (which shall include the execution of an IRS Form 870-AD or successor form) provides otherwise.

SECTION 8.08.                    Survival.  The covenants, agreements, representations and warranties contained in this Agreement shall survive the Closing solely for purposes of Section 8.01 and Section 8.02 and shall terminate at the close of business on the [***] anniversary of the

Closing Date; provided, that (a) the Specified Representations shall survive until the [***] ([***]) anniversary of the Closing Date, (b) the representations and warranties in Section 3.09(a), Section 3.09(b), Section 3.09(d), Section 3.09(e), Section 3.09(g), Section 3.14(a), Section 3.14(h), Section 3.14(i) and Section 3.15(b) shall survive until the [***], (c) the representations and warranties in Section 3.11 shall survive until [***] ([***]) days after the expiration of the statute of limitations applicable to the subject matter thereof and (d) the covenants or agreements contained in this Agreement which by their terms contemplate performance after the Closing Date shall survive the Closing until the expiration of the term of the undertaking set forth in such agreements and covenants.  After the Closing, neither Party shall have any liability or obligation of any nature with respect to any representation or warranty after the termination thereof unless a notice of a breach thereof giving rise to a right of indemnity shall have been given to the Party against whom such indemnity may be sought prior to the termination thereof.  It is the express intent of the parties that each survival period contemplated by this Section 8.08 may be longer than the statute of limitations that may then apply, and by contract, the applicable statute of limitations is hereby increased.

SECTION 8.09.                    Right of Offset.

(a)           In the event that a Purchaser Indemnitee has made a claim in accordance with Section 8.03, subject to the limitations of this Article VIII, Purchaser shall have the right and option (but not the obligation) to offset the amount of such claim (or, if not then known, Purchaser’s good faith estimate of thereof) against any portion of the amounts payable to Seller under this Agreement, including, but not limited to, amounts payable as Milestone Payments pursuant to Section 1.02 hereof, and thereby recoup such amounts (subject to the next sentence) reducing the amounts otherwise payable to Seller.  If such claim has not been finally determined, then, with respect to any amount of such claim in dispute for which Purchaser elects to exercise its offset right in accordance with the preceding sentence, Purchaser shall deposit such amount into an escrow account pursuant to a customary escrow agreement with an independent financial institution, in each case, reasonably satisfactory to Seller.  Such escrow agreement shall provide for the release of the amount in dispute as promptly as practicable after, and in accordance with, the final determination of such claim.

(b)           Subject to Section 8.06, such right of offset, unless and until exercised, shall not limit any injunctive relief or other rights or remedies to which Purchaser is entitled under this Agreement.  In the event Purchaser exercises the right of offset under this Section 8.09 with respect to all or a portion of a claim made by a Purchaser Indemnitee under Section 8.03, the exercise of such right shall be the sole and exclusive remedy available to the Purchaser Indemnitees with respect to such claim or portion thereof made by a Purchaser Indemnitee under Section 8.03.  For the avoidance of doubt, the exercise of such right of offset with respect to a portion of any such claim shall not limit any Purchaser Indemnitee’s rights or remedies with respect to the remaining portion of such claim.

SECTION 9.01.                    Tax Covenants.

(a)           Transfer Taxes.  Each of Purchaser and Seller shall cooperate in timely making all filings, returns, reports and forms as may be required in connection with Purchaser’s payment of Transfer Taxes.  Seller or Purchaser, as applicable, shall execute and deliver all instruments and certificates necessary to enable the other to comply with any filing requirements relating to any such Transfer Taxes.  Transfer Taxes shall be paid by the Party upon whom such Transfer Taxes are levied as a matter of law.

(b)           Except as required by applicable Law, Purchaser covenants that it will not cause or permit the Company or any affiliate of Purchaser (i) to take any action or fail to take any action on or after the Closing Date other than in the ordinary course of business, including the distribution of any dividend or the effectuation of any redemption, (ii) to make any election or deemed election under Sections 338 or 336(e) of the Code or any comparable election under applicable Law with respect to the Company, or (iii) to make or change any Tax election, amend any Tax Return or take any Tax position on any Tax Return, take any action, fail to take any action or enter into any merger, restructuring or other transaction, in each case that would reasonably be expected to give rise to any Tax liability, or reduce any Tax asset, of Seller or any affiliate of Seller in respect of any Pre-Closing Tax Period.

SECTION 9.02.                    Tax Filings and Other Tax Matters.

(a)           Pre-Closing Tax Period Tax Returns.  Seller (or its affiliates) shall prepare and timely file (or cause to be prepared and timely filed) the following Tax Returns on a basis consistent with existing procedures for preparing such Tax Returns and pay Taxes shown as due thereon: (i) all Tax Returns of the Company due on or prior to the Closing Date; (ii) all Income Tax Returns of the Company due after the Closing Date in the case of a combined, consolidated or unitary Income Tax Return that includes an affiliate of Seller which is not being transferred pursuant to this Agreement; and (iii) in the case of the Company, any other Income Tax Return for a taxable period of the Company ending on or before the Closing Date but filed thereafter; provided, that Seller shall deliver any Tax Return described in clause (iii) to Purchaser at least 30 days before it is due for review and comment.

(b)           Straddle Period Tax Returns.

(i)            As to any Tax Return of the Company for a tax period that begins before and ends after the Closing Date (a “Straddle Period”), Purchaser shall cause the Company to prepare and timely file (or cause to be prepared and timely filed) such Tax Return and pay all Taxes due with respect thereto; provided, however, that Seller shall reimburse Purchaser for any amount owed by Seller with respect to such Tax Return in accordance with Section 9.03; provided, further, however, as to any Tax Return for which Seller may be liable for an indemnity under Section 9.03: (A) Purchaser shall deliver any such Tax Return to Seller at least 30 days before it is due, and (B) Seller shall have the right to examine and comment on any such Tax Return prior to the filing thereof.

(ii)           Seller and Purchaser shall make (or cause any of their respective affiliates to make) any election available under Law to treat the Closing Date as the end of a relevant taxable period.

52

(c)           Cooperation.  Seller and Purchaser shall reasonably cooperate, and shall cause their respective affiliates and Representatives reasonably to cooperate, in preparing and filing all Tax Returns of the Company, including maintaining and making available to each other all records necessary in connection with Taxes and in resolving all disputes and audits with respect to all taxable periods relating to Taxes.  Seller and its affiliates will need access, from time to time after the Closing Date, to certain accounting and Tax records and information held by Purchaser or its affiliates (including the Company) to the extent such records and information pertain to events occurring prior to the Closing.  Therefore, Purchaser shall, and shall cause each of its affiliates (including the Company) to, (i) properly retain and maintain such records until such time as Seller agrees that such retention and maintenance is no longer necessary (which period shall not exceed six (6) years from the date on which the applicable Tax Return is filed) and (ii) allow Seller and its affiliates and Seller’s and its affiliates’ respective Representatives, at times and dates mutually acceptable to the Parties, to inspect, review and make copies of such records as Seller may deem necessary or appropriate from time to time, such activities to be conducted during normal business hours and at Seller’s expense.

(d)           Refunds and Credits.  Any refund or credit of Taxes that is related to the Company and is for, relates to, or arises from, any Pre-Closing Tax Period (or other Taxes which Seller has paid under Section 9.03 or Section 8.01) shall be for the account of Seller.  Any other refund or credit of Taxes relating to the Company shall be for the account of Purchaser.  Purchaser shall, if Seller so requests and at Seller’s expense, file for and obtain or cause the Company to file for and obtain any refunds or credits to which Seller is entitled under this Section 9.02(d).  Purchaser and the Company shall permit Seller to control the prosecution of any such refund claim.  If Seller pays (or causes the Company to pay prior to the Closing) estimated Income Taxes for any Straddle Period in excess of the amount ultimately determined to be due for the portion of such Straddle Period ending on the Closing Date, and Purchaser obtains the benefit of such excess payment, Purchaser shall promptly refund such excess to Seller.

(e)           Tax Sharing Agreements.  Seller shall cause any Tax sharing agreement to which the Company is a party to be terminated on or prior to the Closing Date.  After the Closing Date, neither Party to any such Tax sharing agreement shall have any rights or obligations under any such Tax sharing agreement.

SECTION 9.03.                    Tax Indemnification.

(a)           From and after the Closing, Seller shall indemnify and hold harmless Purchaser Indemnitees from and against (i) all liability for Taxes of the Company for the Pre-Closing Tax Period, (ii) all liability of the Company for Taxes of another entity that was a member of an affiliated, combined, consolidated or unitary group of which the Company was a member on or before the Closing Date as a result of Treasury Regulation § 1.1502-6 or any similar provision of state, provincial, local or foreign Law, and (iii) all liability for reasonable legal fees and expenses attributable to any item in clause (i) or (ii) above.  Notwithstanding the foregoing, Seller shall not indemnify or hold harmless any Purchaser Indemnitee from any liability for Taxes to the extent attributable to a breach by Purchaser of Section 9.01(b) or of any other obligation under this Agreement.

53

(b)           In the case of any Straddle Period, the amount of any Taxes based on or measured by income, sales, use, receipts, or other similar items of the Company for the Pre-Closing Tax Period or Post-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date, and the amount of any other Taxes of the Company for a Straddle Period which relate to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in the Straddle Period (with the remaining Taxes for such period allocable to the Post-Closing Tax Period).

SECTION 9.04.                    Procedures Relating to Indemnification of Tax Claims.

(a)           If one Party is responsible for the payment of Taxes pursuant to Section 8.01, Section 8.02, or Section 9.03 (the “Tax Indemnifying Party”), and the other Party to this Agreement (the “Tax Indemnified Party”) receives a notice of deficiency, proposed adjustment, adjustment, assessment, audit, examination, suit, dispute or other claim (a “Tax Claim”) with respect (in whole or in part) to such Taxes, the Tax Indemnified Party shall promptly notify the Tax Indemnifying Party in writing of such Tax Claim.  No failure or delay on the part of the Tax Indemnified Party to give notice to the Tax Indemnifying Party shall reduce or otherwise affect the obligations or liabilities of the Tax Indemnifying Party pursuant to this Agreement, except to the extent that the Tax Indemnifying Party is actually prejudiced thereby.

(b)           The Tax Indemnifying Party shall assume and control the applicable audit or examination and the defense of a Tax Claim involving any Taxes for which it has an obligation to indemnify the Tax Indemnified Party pursuant to Section 8.01, Section 8.02 or Section 8.03, and the Tax Indemnified Party and its affiliates agree to cooperate reasonably with the Tax Indemnifying Party in pursuing such contest, including execution of any powers of attorney in favor of the Tax Indemnifying Party.  Notwithstanding anything to the contrary contained in this Agreement, the Tax Indemnifying Party shall keep the Tax Indemnified Party informed of all material developments and events relating to such Tax Claim, and the Tax Indemnified Party, at its own cost and expense and with its own counsel, shall have the right to participate in (but not control) the applicable audit or examination and defense of such Tax Claim.

(c)           In no case shall any Tax Indemnified Party settle or otherwise compromise (or extend the statute of limitations or period of assessment or reassessment for) any Tax Claim without the Tax Indemnifying Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed.  Neither Party shall settle a Tax Claim relating solely to Income Taxes of the Tax Indemnified Party or any of its subsidiaries for a Straddle Period without the other Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed.
