(b) Product Development.

(i) During the Earn-Out Period, Purchaser shall use Commercially Reasonable Efforts to develop and obtain Regulatory Approval for the marketing of one or more Products.

The Key Employee may not request more than two (2) such meetings with the Chief Executive Officer of Purchaser in any twelve (12) month period.

(iii) Within twelve (12) months after receiving substantially all Phase I data related to the prospectively defined primary endpoint and all pre-specified endpoints, along with a substantially complete safety and tolerability data set with respect to the first Product contemplated by the Phase II Milestone below, Purchaser, in consultation with Seller, will decide whether or not to continue with a Phase II study plan.

(c) Development Progress Meetings. Purchaser shall maintain, and shall cause its Subsidiaries and Licensees to maintain, reasonable documentation, consistent with Purchaser’s customary practices, regarding development activities relating to the efforts undertaken to achieve the conditions required to satisfy the Milestones.

At each Development Progress Meeting, Purchaser’s representatives shall make a presentation covering material developments since the last meeting and respond to Seller’s inquiries in order to reasonably enable Seller to evaluate Purchaser’s compliance with its obligations hereunder; provided that in no event shall Purchaser be required to prepare any documentation that does not then exist.

(iv) Danish Approval Milestones. Upon receipt by Purchaser of the first Regulatory Approval by the applicable Regulatory Authority in Denmark (other than the EMA) for (A) any Product for which Regulatory Approval has not previously been received from the EMA or any other applicable Regulatory Authority in Denmark, or (B) any Product for a Distinct Indication for which Regulatory Approval has not been previously received by the EMA or any other applicable Regulatory Authority in Denmark (each such approval, a “Danish Approval Milestone”), Purchaser shall pay to Seller two hundred thousand dollars ($200,000) (each, a “Danish Approval Milestone Payment”); provided, however, that in no event shall Purchaser be required to pay for any more than four (4) Danish Approval Milestones (eight hundred thousand dollars ($800,000) total).

Notwithstanding the foregoing, in no event will Purchaser be required to pay more than two hundred twenty-five million eight hundred thousand dollars ($225,800,000) in aggregate Milestone Payments pursuant to this Section 1.7.

(e) Notification; Payment.

(i) Purchaser shall notify Seller in writing of the achievement of a Milestone within forty-five (45) days after such occurrence (the “Notification Date”). If the Notification Date occurs prior to the initial public offering of the Purchaser Common Stock, then (A) such notice shall be accompanied by copies of (x) Purchaser’s financial statements for the most recent fiscal quarter and fiscal year and (y) the most recent investor deck and other similar marketing materials provided to investors and prospective investors of Purchaser and (B) if requested by Seller, Purchaser shall make its Chief Financial Officer available for a meeting (by videoconference or in Purchaser’s offices) to address Seller’s questions regarding such materials and such other information concerning the Purchaser and its business, operations and financial condition as Seller may reasonably request to discuss, at such time and date as shall be mutually agreed upon by Purchaser and Seller.

(ii) Thereafter, Purchaser and Seller will negotiate in good faith to agree upon the proportion of each Milestone Payment to be paid in cash versus shares of Purchaser Common Stock. If no agreement is reached by Purchaser and Seller within thirty (30) days after the Notification Date, fifty percent (50%) of such Milestone Payment shall be paid in cash and fifty percent (50%) of such Milestone Payment shall be paid in Purchaser Common Stock, unless Purchaser elects in its sole discretion to pay one hundred percent (100%) of such Milestone Payment in cash.

(iii) Purchaser shall pay or cause to be paid (x) the cash portion, if any, of the applicable Milestone Payment to Seller within ten (10) Business Days after the determination of the proportion of the applicable Milestone Payment to be paid in cash versus shares of Purchaser Common Stock in accordance with Section 1.7(e)(ii), and (y) the stock portion, if any, of the applicable Milestone Payment to Seller within thirty (30) calendar days after the determination of the proportion of the applicable Milestone Payment to be paid in cash versus shares of Purchaser Common Stock in accordance with Section 1.7(e)(ii). The cash portion, if any, of any such Milestone Payment shall be paid by wire transfer of readily available funds to a bank account or bank accounts designated in writing by Seller. The stock portion, if any, shall be paid by the issuance to Seller of a number of shares of Purchaser Common Stock equal to (A) the applicable Milestone Payment, divided by (B) (1) if the Purchaser Common Stock is publicly traded on a national stock exchange, the average daily VWAP for the thirty (30) trading days immediately preceding the fifteenth (15th) day after the date of achievement of the applicable Milestone, or (2) if the Purchaser Common Stock is not traded on a national stock exchange, the original issue price per share at which shares of Purchaser preferred stock were issued in Purchaser’s last round of preferred stock financing, as set forth in the Purchaser’s Certificate of Incorporation as then in effect (any such shares are referred to herein as “Acquisition Shares”).

(iv) Notwithstanding the foregoing, payment of the stock portion of any Milestone Payment shall be conditioned upon (A) the representations and warranties of Purchaser in Section 3.5 hereof being true, correct and complete as of the Closing Date and as of the date of issuance of such Acquisition Shares; (B) the representations and warranties of Seller in Section 2.24 hereof being true, correct and complete as of the Closing Date and as of the date of issuance of such Acquisition Shares (excluding the representation set forth in clause (c) thereof if, at such time, the Purchaser Common Stock is traded on a national stock exchange); (C) if Purchaser Common Stock is not traded on a national stock exchange, and if required by Purchaser, Seller’s (and if a distribution is to be made of such shares by Seller to the Seller Members, each Seller Member’s (including any Permitted Transferee’s)) execution and delivery to Purchaser of a joinder agreement or counterpart signature page to (1) the Amended and Restated Right of First Refusal and Co-Sale Agreement, dated as of February 13, 2019, by and among Purchaser and the stockholders party thereto, as amended from time to time (the “ROFR Agreement”), making Seller (or such Seller Member) a party to such agreement as a Key Holder, and (2) the Amended and Restated Voting Agreement, dated as of February 13, 2019, by and among Purchaser and the stockholders party thereto, as amended from time to time (the “Voting Agreement”), each in form reasonably satisfactory to Purchaser; and (D) the execution by Seller and each Seller Member (including any Permitted Transferee) of such other documents, agreements, certifications, and representations as Purchaser may reasonably request solely to the extent each such document, agreement, certification and representation is (1) in furtherance of the restrictions on transfer and voting contemplated by this Section 1.7(e)(iv) or (2) determined in good faith by Purchaser to be necessary to satisfy applicable securities Law requirements, including, if a distribution is to be made of such shares by Seller to the Seller Members, representations and warranties from each Seller Member (including each Permitted Transferee) equivalent to those set forth in Section 2.24. In the event that the conditions set forth in clauses (B) – (D) of the immediately preceding sentence have not been satisfied by Seller and, to the extent applicable, the Seller Members (including any Permitted Transferee)

(each, for purposes of this Section 1.7(e)(iv), a “default”), within 180 days after determination of the proportion of the applicable Milestone Payment to be paid in cash versus shares of Purchaser Common Stock in accordance with Section 1.7(e)(ii), then (i) Purchaser may provide written notice of such default to the defaulting party and the defaulting party shall have twenty (20) Business Days after delivery thereof in accordance with Section 8.4 to cure such default, (ii) if such default is not cured within such twenty (20) Business Day period, Purchaser may provide a second written notice of default to the defaulting party and unless any such default is cured within twenty (20) Business Days after delivery of such second written notice of default in accordance with Section 8.4, (x) in the case of a default by a Seller Member (including any Permitted Transferee), the stock portion of such Milestone Payment otherwise distributable to such defaulting Seller Member (including any Permitted Transferee) shall be cancelled and permanently forfeited, and (y) in the case of a default by Seller, all of the stock portion of such Milestone Payment shall be cancelled and permanently forfeited. In furtherance thereof, any such Seller Member so defaulting irrevocably waives its entitlement to any equity Milestone Payment received by Seller on behalf of any non-defaulting Seller Members and agrees to execute such further documentation, if any, as may be necessary or appropriate to effect such pro rata waiver.

(v) In addition, the payment date for the stock portion of any such Milestone Payment may be delayed as reasonably necessary to allow Purchaser to comply with or to obtain any governmental, regulatory, board, stockholder or other third-party consents necessary to effect such stock issuance in compliance with all applicable Laws and Purchaser’s then-existing agreements. In the event that Purchaser is unable to do so within 90 days (provided that if Purchaser determines that (A) any consent or approval of any Governmental Entity is necessary in connection with the payment of the stock portion of such Milestone Payment or (B) if Purchaser is then subject to the periodic reporting requirements of the Securities Exchange Act of 1934, as amended, the approval of Purchaser’s stockholders is necessary in connection with the payment of the stock portion of such Milestone Payment, then such period shall be extended to 180 days) after determination of the proportion of the applicable Milestone Payment to be paid in cash versus shares of Purchaser Common Stock in accordance with Section 1.7(e)(ii), Purchaser shall make the applicable payment in full in cash in lieu of stock.

(vi) Each of Purchaser and Seller (A) shall, and shall cause their respective affiliates to, treat all Earn-Out Payments made pursuant to this Agreement as additional Purchase Price for U.S. federal and applicable state and local income tax purposes, and (B) shall not, and shall not cause or permit their respective affiliates to, take any position on any Tax Return or before any Tax authority inconsistent with such treatment, except, in each case, to the extent otherwise required by a change in law after the date hereof or pursuant to a “final determination” by the Internal Revenue Service under Section 1313 of the Code.

(f) Remedies & Limitations.

(i) If Seller believes in good faith that Purchaser has breached its obligations under this Section 1.7, then Seller shall provide Purchaser with written notice thereof, which notice shall specify in reasonable detail the alleged breach (a “Notice of Breach”).

(ii) If Seller reasonably determines that Purchaser has not satisfied or likely will not satisfy the spending requirements set forth in Section 1.7(b)(ii) within the period set forth therein (collectively, the “Spending Requirements”), then Seller shall send Purchaser a written notice of negotiation (the “Negotiation Notice”). Upon receipt by Purchaser of the Negotiation Notice, both parties shall negotiate in good faith for a period of up to three (3) months to determine whether or not a breach of the Spending Requirements has occurred, and, if necessary, the creation of a revised budget and related timeline (the “Revised Spending Requirements”). If the parties adopt the Revised Spending Requirements in lieu of the Spending Requirements, then Purchaser shall be required to effect the spending contemplated

thereby within the time period specified therein. If the parties do not adopt the Revised Spending Requirements, then Purchaser shall remain free to satisfy the original Spending Requirements by completing the expenditures contemplated thereby within the later of (A) the original three years contemplated by the Spending Requirements plus a twelve (12) month cure period, and (B) twelve (12) months after receipt of such Notice of Negotiation. If Purchaser nonetheless breaches either the Spending Requirements or the Revised Spending Requirements, as applicable, then Seller’s sole remedy for such breach shall be for Seller to cause Purchaser to effect an Assignment Transaction pursuant to Section 1.8. To exercise such remedy, Seller must give written notice thereof to Purchaser within three (3) months after the end of the cure period set forth this paragraph.

(iii) If, prior to the earlier of achievement of the Phase II Milestone and a Termination Decision, Purchaser materially breaches its covenant to use Commercially Reasonable Efforts as provided herein, and fails to reasonably remedy any such breach within three (3) months after receipt of a Notice of Breach, then Seller’s sole remedy for such breach shall be either (A) to cause Purchaser to effect an Assignment Transaction pursuant to Section 1.8, or (B) to pursue a breach claim for monetary damages arising from the alleged breach by Purchaser, but not both. To exercise the remedy, Seller must give written notice thereof to Purchaser within three (3) months after the end of the cure period set forth in the immediately preceding sentence.

(iv) If, after the achievement of the Phase II Milestone, Purchaser materially breaches its covenant to use Commercially Reasonable Efforts as provided herein and fails to remedy such breach within three (3) months after receipt of a Notice of Breach, then Seller’s sole remedy shall be to pursue a breach claim for monetary damages arising from the alleged breach by Purchaser. To exercise such remedy, Seller must give written notice thereof to Purchaser within three (3) months after the end of the cure period set forth in the immediately preceding sentence

(v) Except with respect to an Assignment Transaction as provided herein, in no event shall Seller be entitled to pursue specific performance or an injunction as a remedy for any breach of the terms of Section 1.7.

(vi) Disputes pursuant to this Section 1.7 shall be subject to the arbitration provisions set forth in Section 8.8. During any such arbitration process, the time periods set forth in this Section 1.7(f) will be tolled.

(g) Miscellaneous.

(i) Notwithstanding the foregoing, with respect to the decision of whether or not to proceed with development efforts through the Phase II Milestone, Commercially Reasonable Efforts may not give effect to other Purchaser product portfolio opportunities (other than other potential Products opportunities) and related financial considerations that are unique to Purchaser and not shared by other industry participants.

(ii) If Purchaser sells, assigns, exclusively licenses or otherwise transfers all or substantially all of the assets of the Company, as such assets exist on the date hereof, during the Earn-Out Period, Purchaser shall cause the acquirer to agree in writing to fulfill Purchaser’s obligations pursuant to this Section 1.7 and Section 1.8; provided that the provisions of Section 1.8(c) shall continue to apply to Purchaser in addition to such acquirer.

(iii) The right of Seller to receive any portion of any Earn-Out Payment: (A) is solely a contractual right and is not a security for purposes of any federal or state securities Laws (and shall confer upon such Person only the rights of a general unsecured creditor under applicable state Law), (B) will not be represented by any form of certificate or instrument, (C) is not redeemable, and (D) may not be Transferred and any purported Transfer in violation of this clause shall be null and void.

(iv) Nothing in this Section 1.7 shall (A) create any employment right or entitlement of any Person that is an employee of the Company prior to the Closing Date, or any Person that is an employee of Purchaser after the Closing Date; (B) represent an ownership interest in Purchaser; or (C) create any fiduciary duty on the part of Purchaser to any Person with respect to any Earn-Out Payment. Except as set forth in the development covenants set forth in Section 1.7(b) above and Section 1.7(g)(i), Purchaser assumes no obligation or commitment to cause the realization of any Milestone. In furtherance thereof, Seller acknowledges that the development of the technology acquired hereby consistent with the terms hereof may not result in the realization of any Milestone payments contemplated hereby.

(v) Subject to Section 6.6(f) hereof, any Earn-Out Payment that is payable to Seller shall be reduced by the Offset Amount (as defined below), if any, as of the date immediately prior to the payment date of the Earn-Out Payment.

(vi) Purchaser hereby agrees that if Purchaser or any of its Affiliates, including any other Subsidiaries of Purchaser after the Closing, files for relief under the United States Bankruptcy Code (the “Bankruptcy Code”), or otherwise becomes subject to a Proceeding under the Bankruptcy Code, it shall use its commercially reasonable efforts to obtain as soon as reasonably practicable the entry of an order from the applicable bankruptcy court, pursuant to the provisions of the Bankruptcy Code (including sections 105 and 365 of the Bankruptcy Code), authorizing and directing Purchaser to assume this Agreement and the payments contemplated hereunder. Purchaser and Seller agree that if required pursuant to such an order, the Earn-Out Amount may be paid to Seller in the form of subordinated notes, provided that the unpaid principal amount of such subordinated notes shall accrue interest at a rate per annum equal to the prime rate as published in The Wall Street Journal, in effect on the date such payment is required to be made, compounding quarterly from the date such payment was required to be made through the date such payment was actually received.

Section 1.8 Assignment Transaction; Right of First Negotiation.

(a) Notice of Termination Decision. If Purchaser’s chief executive officer affirmatively determines in his or her discretion to terminate and abandon all development activities with respect to all Products prior to the end of the Earn-Out Period, then he or she will submit such recommendation to Purchaser’s board of directors, and if Purchaser’s board of directors in its discretion affirmatively concurs with such determination in due course (such decision, a “Termination Decision”), Purchaser shall promptly thereafter (and in any event within ten (10) Business Days) send written notice thereof to Seller. If Seller desires to accept the assignment of the assets and assume the related liabilities described in clause (b) below pursuant to the terms thereof (the “Assignment Election”) and/or exercise a right of first negotiation pursuant to clause (c) below (the “Negotiation Election”), Seller shall deliver written notice of its election to do so to Purchaser within three (3) months after receipt of notice of the Termination Decision. If Seller does not provide either such notice within such period, then Purchaser shall have no further obligation with respect to this Section 1.8. As used in Section 1.8(b) below only, the term “Assignor” means Purchaser, as assignor; the term “Assignee” means Seller or its designated assignee, as assignee; and the term “Assignment Transaction” means the transfer of the Assigned Assets (as defined below), the assumption of the Assumed Liabilities (as defined below) and the license of the Licensed Data (as defined below).

(b) Assignment of Assets and Assumption of Liabilities. Subject to the limitations and conditions herein, following receipt of an Assignment Election, the Assignor and Assignee agree to incorporate the following terms and conditions into definitive agreements that effect the Assignment Transaction (the “Definitive Agreements”):

(D) any registered trademark then maintained by Assignor that includes the word “Oscine”.

For the avoidance of doubt, except as expressly set forth above, the Assigned Assets shall not include any assets of Purchaser existing prior to the Closing or arising thereafter, including any assets developed, purchased, acquired or in-licensed by Assignor after the Closing, or any assets of any licensor, partner, acquirer, Affiliate (other than a wholly-owned Subsidiary of Assignor) or parent entity of Assignor.

The foregoing assignment shall be made on an “as is” basis, without representation or warranty from the Assignor of any type, whether express or implied, including the sufficiency of the Acquired Assets for any purposes, or any implied warranty of merchantability, fitness for a particular purposes or non-infringement. The Assigned Assets shall be subject to any and all joint ownership rights or obligations, licenses or other Liens of Assignor (other than any security interest in the assets of Assignor generally) relating to the Assigned Assets as in effect at the time of the Assignment Transaction or arising thereafter. The Assigned Assets shall not include the transfer of any asset or any interest therein which Assignor is unable to effect unilaterally, except to the extent such consent is expressly obtained, as provided below.

(ii) Assumed Liabilities.

The Retained Liabilities shall remain the sole and exclusive Liabilities of Purchaser.

(iii) Licensed Data. Subject to the applicable terms and conditions of this Agreement, Assignor shall agree to license to Assignee on a non-exclusive, royalty-free, worldwide, perpetual basis Assignor’s right and interest, if any, in or to clinical trial data generated by or on behalf of Assignor under a study protocol for any clinical trial investigating the safety or efficacy of any Product and in which such Product is administered to study subjects enrolled under such study protocol (the “Licensed Data”), solely for use of such data by Assignee in the field of treatment of neurologic disorders with therapeutic products that comprise (A) GPCs, including oligodendrocyte progenitor cells or astrocyte progenitor cells, derived from ESCs or iPSCs, (B) cells derived from GPCs derived from ESCs or iPSCs, or (C) oligodendrocytes or astrocytes derived from ESCs or iPSCs (the “Licensed Field”). Assignee shall not be entitled to sell, assign, sublicense or otherwise transfer the Licensed Data, any portion thereof, or any license thereto granted by Assignor pursuant to the foregoing sentence, except that any such license to the Licensed Data shall be (1) sublicensable by Assignee solely in connection with a sublicense of all or substantially all of (a) the Assigned Assets (to the extent then in existence) and (b) the intellectual property rights then in existence that are owned or controlled by Assignee that at any time were the subject of or within the Assigned Assets, in furtherance of Assignee’s research, development and/or commercialization of therapeutic products in the Licensed Field and (2) transferrable by Assignee to an acquiror of all of the Assigned Assets, in each case (1) or (2) with Assignor’s prior written consent, which shall not be withheld if such sublicense complies with the terms and conditions of the license for the Licensed Data. Any such license (and any sublicense or transfer of such license as described in the foregoing sentence) for the Licensed Data shall contain and be subject to confidentiality, non-disclosure and indemnification provisions reasonably acceptable to Assignor. Any such license shall be made on an “as is” basis, without representation or warranty from the Assignor of any type, whether express or implied, including the sufficiency of the Licensed Data for any purposes, or any implied warranty of merchantability, fitness for a particular purposes or non-infringement. The Licensed Data shall be subject to any and all joint ownership rights or obligations, licenses or other Liens of Assignor relating to the Licensed Data as in effect at the time of any such license, including any third party rights created or arising subsequent to the Closing Date. The Licensed Data shall not include any data or any interest therein which Assignor is unable to license unilaterally without violation of any applicable Law or any contractual, privacy, or study subject informed consent restrictions, limitations or obligations, except to the extent any applicable consent or waiver is expressly obtained, as provided below.

(iv) Indemnification.

(A) Assignee shall agree to indemnify, hold harmless and reimburse Assignor, its Affiliates and their employees, directors, agents and representatives for any and all Damages incurred or sustained by them, including Damages arising from third party claims, to the extent such Damages arise from or relate to (1) the consummation of the Assignment Transaction, including any failure to obtain any Required Consent, (2) the operation of the business relating to the Assigned Assets or use of the Licensed Data by Assignee after the closing of the Assignment Transaction, and (3) the Assumed Liabilities.

(B) Assignor shall agree to indemnify, hold harmless and reimburse the Assignee, its Affiliates and their employees, directors, agents and representatives for any and all Damages incurred or sustained by them, including Damages arising from third party claims, to the extent such Damages arise from or relate to the operation of the business relating to the Assigned Assets and Licensed Data prior to the closing of the Assignment Transaction (other than the Assumed Liabilities).

(C) The Assignment Transaction shall be permitted by applicable Law, and no Governmental Entity shall have issued or entered any stay, decree, judgment, injunction, statute, rule or regulation which makes the Assignment Transaction illegal or prohibits it;

(D) No Proceeding shall be pending or threatened against the Assignor with respect to the Assigned Assets, the Assumed Liabilities or the Licensed Data; and

To assert any breach contemplated hereby, Assignee must provide written notice to Assignor promptly following the occurrence thereof and in any event prior to such six-month date.

(i) Subject to the limitations and conditions herein, following receipt of a Negotiation Election, Purchaser hereby grants to Seller a right of first negotiation on the terms set forth in this Section 1.8(c) with respect to a license to or assignment of Purchaser’s right, title and interest in and to the following assets, to the extent reasonably necessary or desirable to further any research relating to, or the development of, the Assigned Assets by Assignee following an Assignment Transaction, and all associated liabilities:

(A) all previously granted regulatory approvals, to the extent exclusively possessed by Purchaser or its Subsidiaries, that are solely related to and useful only in connection with the Assigned Assets or any Product;

(D) any modified cell lines, including any master cell bank and any working cell banks, generated by Purchaser or its Subsidiaries in the course of any research or development activities relating to any Product that are solely related to and useful only in connection with the Assigned Assets or any Product.

To the extent not transferred or assigned pursuant to Section 1.8(b), such assets, collectively, are referred to herein as the “Program Assets”. Purchaser and Seller shall negotiate in good faith a term sheet setting forth the terms and conditions of a license to or assignment of the Program Assets (the “Program License”), including the structure and economics thereof, for a period of three (3) months from Purchaser’s receipt of notice of exercise of the Negotiation Election (the “Negotiation Period”). If Purchaser and Seller enter into a term sheet with respect to the Program License on mutually acceptable terms within the Negotiation Period, the Negotiation Period shall be automatically extended for an additional three (3) months, during which period Purchaser and Seller shall negotiate in good faith the definitive documentation for the Program License. If the Program License is not entered into within the Negotiation Period then Purchaser shall have no further obligations pursuant to this Section 1.8(c) and this Section 1.8(c) shall terminate (x) at the end of the Negotiation Period, if Purchaser has not breached, in any material respect, the covenants set forth in this Section 1.8(c), or (y) on the earlier of (A) the date Purchaser shall have cured any such breach and (B) the twentieth (20th) Business Day after receipt of written notice of breach from Seller.

To the extent that the Program Assets include any in-bound license agreement under Section 1.8(c)(i)(C), (1) Purchaser’s obligations under this Section 1.8(c)(i) with respect to such license agreement shall be satisfied by introducing Seller to the licensor and reasonably cooperating with Seller to effect an assignment of such license agreement or termination of such agreement to permit Assignee to enter into a direct license agreement with the licensor and (2) any out-of-pocket costs, expenses or incremental Liabilities, including any termination or other fees, incurred by Purchaser or its Subsidiaries in connection with actions under this Section 1.8(c)(i) with respect to such license agreement shall be at the expense of Seller (on behalf of Assignee); provided, however, that such expenses borne by Seller shall specifically exclude the first $5,000 of out-of-pocket legal fees and disbursements incurred by Purchaser or its Subsidiaries with respect to each such license.

(ii) During the Negotiation Period, Purchaser and Seller shall also discuss the terms and conditions of a non-exclusive license to Purchaser’s right, title and interest in and to the following assets, to the extent necessary or appropriate to further the development of the Assigned Assets by Assignee following an Assignment Transaction, and all associated liabilities:

(B) any other Intellectual Property Rights developed by Purchaser or its Subsidiaries that are derived from and related to the Assigned Assets or any Product, but that also are or may be useful for Purchaser activities other than the Products;

(C) any data then exclusively owned by Purchaser or its Subsidiaries arising directly out of any clinical trial conducted with respect to a Product that also is or may be useful for Purchaser activities other than the Products; and

(D) any modified cell lines, including any master cell bank and any working cell banks, generated by Purchaser or its Subsidiaries in the course of any research or development activities relating to any Product that also are or may be useful for Purchaser activities other than the Products.

Such assets are collectively referred to herein as the “Additional Assets”.

(iii) Notwithstanding the foregoing, (A) neither the Program Assets nor the Additional Assets shall include any assets of any acquirer, Affiliate (other than a wholly-owned Subsidiary of Purchaser) or parent entity of Purchaser; provided, that such assets were not transferred to such entity by Assignor solely for the purpose of avoiding its obligations hereunder, and (B) the parties acknowledge and agree that, subject to compliance with the obligation to negotiate in good faith set forth in Section 1.8(c)(i) above, neither Purchaser nor Seller has any obligation to license the Program Assets or the Additional Assets, whether at fair market value or otherwise.

(d) Miscellaneous. Purchaser shall not effect any sale, assignment, license or other transfer of the Assigned Assets, or any portion thereof, the sole or primary purpose of which is to avoid an Assignment Transaction. Except as set forth in the immediately preceding sentence, nothing in this Section 1.8 shall impose or imply any limitation, condition or restriction on the ability of Purchaser or its Affiliates to develop, commercialize or exploit any of the assets or business acquired pursuant to this Agreement, it being acknowledged and agreed that Purchaser shall remain free to operate its business in its discretion. In furtherance thereof, except as set forth in the first sentence of this Section 1.8(d), nothing in

this Section 1.8 shall (i) impose or imply any requirement by Purchaser to maintain exclusive ownership of any asset contemplated hereby; or (ii) prohibit or limit Purchaser from (A) amending any agreement with a third party relating to any of the assets contemplated hereby, (B) entering into any research, development, licensing, partnering or other commercial arrangements with respect to the assets contemplated hereby or limit the terms that Purchaser may agree to with respect thereto; (C) granting any lien or security interest or otherwise encumbering any of the assets contemplated hereby; or (D) transferring or selling any or all of the assets contemplated hereby or the sale of Purchaser, subject to the limitations of Section 1.7(g)(ii). In furtherance thereof, Seller acknowledges that the operation of the business by Purchaser after the Closing may diminish or even extinguish the value of the assets and related business covered by this Section 1.8 and the ability of Purchaser to effectively assign, sell or transfer the assets contemplated hereby.

Seller and the Seller Members shall maintain the confidentiality of, and not disclose to any third party, without the consent of Purchaser, the existence and terms of this Agreement and the transactions contemplated hereby (including any claim or dispute arising out of or related to this Agreement, or the interpretation, making, performance, breach or termination hereof and the reasons therefor) or any other nonpublic, confidential or proprietary information concerning the transactions contemplated hereby or the Company except (i) to its or their respective legal, accounting and financial advisors that are bound by confidentiality restrictions, (ii) to the extent such information was previously publicly disclosed by Purchaser, (iii) to the extent such disclosure is required by applicable Law, in which case the party required to disclose such information shall promptly notify Purchaser of such disclosure and cooperate at Purchaser’s expense with Purchaser to the extent practicable so as to seek to limit the information disclosed to the information required by applicable Law to be disclosed and will, to the extent practicable and at Purchaser’s expense, seek to obtain a protective order over, or confidential treatment of, such information, and (iv) for disclosures in dispute resolution proceedings to the courts or arbitrators involved in such proceedings and to other Persons involved in such proceedings (e.g., attorneys and expert witnesses) that are bound by confidentiality obligations; provided, that such proceedings are brought in compliance with this Agreement, including Section 6.6 or Section 8.8, as applicable.

Section 4.3 Tax Matters.

(a) Purchaser shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company for any Pre-Closing Tax Period that are required to be filed after the Closing Date taking into account any applicable extensions. Such Tax Returns shall be prepared, subject to the requirements of applicable Law, in accordance with past practice of the Company and, in the case of the United States federal income tax return Form 1120, shall be subject to Seller’s approval (which approval shall not be unreasonably withheld or delayed) and shall be delivered to Seller at least fifteen (15) calendar days prior to the due date (or if less than fifteen (15) days remain before filing is due, one third (¹⁄₃) of the days remaining between Closing and the filing due date to the extent feasible) for review and approval. Within five (5) Business Days following the delivery of such Tax Return to Seller, the Seller shall notify

Purchaser of any dispute of any item contained therein, which notice shall set forth in reasonable detail the basis for such dispute. If Seller fails to notify Purchaser of any dispute within such five (5) Business Day period, such Tax Return shall be deemed to be accepted by Seller. If Seller notifies Purchaser in writing of any objection regarding such Tax Return within the time periods set forth in this Section 4.3(a), Purchaser and Seller shall cooperate in good faith to resolve such dispute as promptly as possible. If Purchaser and Seller are unable to resolve the dispute within five (5) Business Days after receipt of such objection, Seller shall submit such disputed items to a nationally recognized accounting firm reasonably acceptable to both the Seller and Purchaser (for purposes of this Section 4.3, the “Independent Accountants”) for resolution. The Independent Accountants shall, within forty-five (45) calendar days following its selection, deliver to Purchaser and Seller a written report setting forth its determination as to such disputed items (and only such disputed items), and its determinations will be conclusive and binding upon the parties thereto for the purposes hereof. If the Independent Accountants cannot resolve the dispute before the Tax Return that is the subject of a disagreement is due, such Tax Return shall be filed as prepared by Purchaser, subject to an amendment of the Tax Return upon resolution. The fees and disbursements of the Independent Accountants shall be apportioned equally (50/50) between Seller (on behalf of the Seller Members), on the one hand, and Purchaser, on the other hand.

(b) For purposes of this Agreement, in the case of any Taxes of the Company that are payable with respect to any Tax period beginning prior to the Closing Date and ending after the Closing Date (a “Straddle Period”), the portion of any such Taxes that relates to the Pre-Closing Tax Period shall: (i) in the case of real, personal and intangible property Taxes (and any other Taxes not based on or measured by income or receipts), equal the amount of such Tax for the entire period multiplied by a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending at the end of the day that is the Closing Date and the denominator of which is the number of days in such Straddle Period; and (ii) in the case of all other Taxes, equal the amount due for such other Taxes as if the Company had performed an interim closing of the books as of the close of business on the Closing Date. For purposes of clause (ii) of the preceding sentence, any exemption, deduction, credit or other item (including the effect of any graduated rates of Tax) that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the total amount of such item allocated to the Straddle Period times a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

(c) Purchaser shall be responsible for, and shall have sole discretion with respect to, all Tax Returns required to be filed by the Company with respect to any taxable period that begins after the Closing Date.

(d) Purchaser and Seller shall provide each other with such cooperation and assistance as may be reasonably requested by either of them in connection with any audit or other examination by any Tax Authority, or any judicial or administrative proceedings relating to liability for Taxes, until the seventh (7th) anniversary of the Closing Date, and each will retain and provide the other with any records or information which may be necessary for such Tax Return Audit, or examination, proceedings or determination. Notwithstanding the foregoing or any other provision herein to the contrary, in no event will Seller be entitled to review or otherwise have access to any Tax Return, or information related thereto, of Purchaser or its Affiliates (other than in respect of the Company for any Pre-Closing Tax Period).

(e) Purchaser shall notify Seller in writing within fifteen (15) calendar days from receipt of written notice by Purchaser or its Affiliates (including on or after the Closing Date, the Company) of any pending or threatened assessment or claim in any audit, litigation or other proceeding relating to any Tax Return or Taxes of the Company for any taxable period on or before the Closing Date

and any Straddle Period (a “Tax Contest”). Purchaser shall have the right to control any such Tax Contests, including the settlement or other disposition thereof, provided, that (i) Seller shall have the right to participate, at its own expense, in any such Tax Contests that may give rise to an indemnification claim pursuant to Article VI, (ii) Purchaser shall consider in good faith any reasonable comments of Seller with respect to the conduct of such Tax Contests, (iii) Purchaser shall keep Seller reasonably informed of the status of such matter (including providing the Seller with copies of all material written correspondence with a taxing authority regarding such matter) and (iv) Purchaser shall have the right to settle, adjust or compromise any Tax Contest without the consent of the Seller; provided, however, that if Purchaser settles, adjusts or compromises any Tax Contest without the consent of the Seller, such action shall not be deemed conclusive of the existence of an indemnifiable claim or the amount of Damages for purposes of Article VI and no amounts shall be payable by the Seller Members pursuant to Article VI until a Notice of Claim is delivered pursuant to Section 6.6 and any portion of the Claimed Amount set forth therein is determined in accordance with the terms of Section 6.6 to constitute an Agreed Amount, Stipulated Amount and/or Award Amount, in which case any such amount shall be payable in accordance with Section 6.6. Failure to comply with this section shall not affect Purchaser’s right to indemnification pursuant to Article VI except to the extent such failure actually prejudices Seller’s rights with respect to such Tax Contest.

(f) Seller shall be entitled to all refunds of Taxes of the Company paid in respect of any Pre-Closing Tax Period, but only to the extent such refunds are actually received in cash or applied against cash Taxes actually payable. To the extent that any such amounts are received after the Closing by Purchaser or any of its Affiliates (including, after the Closing, the Company), Purchaser shall pay (or cause to be paid) to Seller such amounts, net of any reasonable out-of-pocket expenses incurred in obtaining such refund.

To the extent that indemnifiable Damages exceed or may exceed the Holdback Amount and any Earn-Out Payment then payable pursuant to Section 1.7, they shall, subject to the limitations set forth in this Section 6.4 and Section 6.6, be recoverable in any manner permitted by applicable Law; provided, however, than Damages arising from or relating to any inaccuracy in or breach of the Intellectual Property Reps shall be satisfied solely in accordance with the first sentence of this clause (b), except in the case of any knowing and intentional misrepresentation or fraud by Seller with respect thereto, which may be recoverable in any manner permitted hereunder.

(c) The amount of any Damages for which indemnification is provided under this Article VI shall take account of and be reduced, to the extent necessary to prevent double recovery by an Indemnified Party, by (i) any indemnification or contribution payments actually recovered by such Indemnified Party from any third party, net of any expenses reasonably incurred in connection with the recovery of such amounts, and (ii) the amount of any insurance proceeds actually received by such Indemnified Party in respect thereof, net of any out-of-pocket expenses reasonably incurred in connection with the recovery of such amounts, in each case only to the extent that such amounts are recovered as a result of and reasonably related to the facts and circumstances giving rise to such Damages (each source identified in clauses (i) and (ii), a “Collateral Source”). In the event that any Damages become payable to an Indemnified Party pursuant to this Article VI or otherwise, such Damages shall become immediately due and payable, regardless of whether amounts payable from a Collateral Source, if applicable, have been determined. Notwithstanding the foregoing, no Indemnified Party shall have any obligation to pursue any Collateral Source with respect to any Damages or indemnification pursuant to this Article VI.

(d) No Indemnified Party shall have any right to indemnification pursuant to Section 6.1(a)(i) or Section 6.1(a)(v) in respect of Taxes of the Company to the extent such claim arises out of or is attributable to Purchaser or its Affiliates (including, after the Closing, the Company) having, after the Closing: (A) filed an amended income Tax Return of the Company with respect to a Pre-Closing Tax Period for which an income Tax Return was filed prior to the Closing, or (B) made, changed or revoked a Tax election with retroactive effect to a Pre-Closing Tax Period, except, in either case, as reasonably required to cause the Company’s Tax Returns and/or Tax elections to comply with all applicable Laws.

(e) Seller and the Seller Members shall not have any right of contribution, indemnification or right of advancement from Purchaser or any of its Affiliates with respect to any Damages claimed by an Indemnified Party.

Section 6.5 Defense of Third Party Claims(a) . In the event of the assertion or commencement by any Person of any claim or Proceeding with respect to which an Indemnified Party may be entitled to indemnification pursuant to this Article VI, such Indemnified Party shall have the right, at its election, to proceed with the defense of such claim or Proceeding on its own. If such Indemnified Party so proceeds with the defense of any such claim or Proceeding:

(a) subject to the other provisions of this Article VI, all expenses (including attorney’s fees) relating to the defense of such claim or Proceeding (and all amounts due pursuant to any settlement, adjustment or compromise with respect to such claim or Proceeding) shall be borne and paid exclusively by the Seller Members;

(b) Seller and the Seller Members shall make available to the Indemnified Party any documents and materials in their possession or control that may be necessary to the defense of such claim or Proceeding;

(c) the Indemnified Party shall consult with Seller regarding, and Seller will be entitled to participate in the defense of, any such claim or Proceeding on behalf of the Seller Members at the sole cost and expense of the Seller (on behalf of the Seller Members) (but not to appear of record or communicate with the Person asserting any such claim or Proceeding or its Representatives), and to receive, upon request copies of all pleadings, notices and settlement offers related thereto; and

(d) the Indemnified Party shall have the right to settle, adjust or compromise such claim or Proceeding without the consent of the Seller; provided, however, that if the Indemnified Party settles, adjusts or compromises any claim or Proceeding without the consent of the Seller, such action shall not be deemed conclusive of the existence of an indemnifiable claim or the amount of Damages for purposes of this Article VI and the Seller Members’ obligation to indemnify any Indemnified Party in connection with such claim or Proceeding shall be subject to the last sentence of this Section 6.5(d).

An Indemnified Party will give the Seller notice after it has been served in connection with the commencement of any such claim or Proceeding against any Indemnified Party; provided, however, that any failure on the part of any Indemnified Party to so notify the Seller will not limit any of the obligations of Seller or the Seller Members, or any of the rights of any Indemnified Party, under this Article VI, except to the extent such failure materially prejudices the defense of such Proceeding. If an Indemnified Party does not elect to proceed with the defense of any such Proceeding, the Seller may proceed with the defense of such Proceeding with counsel reasonably satisfactory to the Indemnified Party or Indemnified Parties; provided, however, that the Seller may not settle or compromise any such Proceeding without the prior written consent of the Indemnified Party or Indemnified Parties, unless such settlement (x) is limited to monetary damages that are fully indemnified and paid to Purchaser and does not provide for injunctive or other non-monetary relief affecting any Indemnified Party, (y) does not include any finding or admission of violation of Law or the rights of any Person by any Indemnified Party or affect any other claim that may be made against any Indemnified Party, and (z) includes an unconditional release of each Indemnified Party from all liabilities in connection with such Proceeding. No amounts shall be payable by the Seller Members pursuant to this Section 6.5 until a Notice of Claim is delivered pursuant to Section 6.6 and any portion of the Claimed Amount set forth therein is determined in accordance with the terms of Section 6.6 to constitute an Agreed Amount, Stipulated Amount and/or Award Amount, in which case any such amount shall be payable in accordance with Section 6.6.

(e) The above provisions of this Section 6.5 shall not apply to any Third Party Claim that is a Tax Contest (which, for the avoidance of doubt, shall be governed by Section 4.3(e)).

Section 6.6 Claim Procedures. Any claim for indemnification pursuant to this Article VI will be brought and resolved exclusively in accordance with this Section 6.6.

(a) Notice of Claims for Indemnification. If any Indemnified Party has incurred or suffered or believes that it may incur or suffer, Damages for which it is or may be entitled to be held harmless, indemnified, compensated or reimbursed under this Article VI, such Indemnified Party may deliver a notice of claim (a “Notice of Claim”) to Seller. Each Notice of Claim shall: (i) state that such

Indemnified Party believes that such Indemnified Party is or may be entitled to indemnification, compensation or reimbursement under Article VI of the Agreement; (ii) contain a brief description of the circumstances supporting such Indemnified Party’s belief that such Indemnified Party is so entitled to indemnification; and (iii) if practicable, contain a non-binding, preliminary, good faith estimate of the aggregate dollar amount of actual and potential Damages that have arisen and may arise as a result of such circumstances (the aggregate amount of such estimate, as it may be modified in good faith by such Indemnified Party from time to time, being referred to as the “Claimed Amount”).

(b) Objecting to Claims for Indemnification. During the thirty (30) day period commencing upon delivery by an Indemnified Party to Seller of a Notice of Claim (the “Dispute Period”), Seller may deliver to the Indemnified Party who delivered the Notice of Claim a written response (the “Response Notice”) in which Seller: (i) agrees that the full Claimed Amount is owed to the Indemnified Party; (ii) agrees that part, but not all, of the Claimed Amount (the “Agreed Amount”) is owed to the Indemnified Party; or (iii) indicates that no part of the Claimed Amount is owed to the Indemnified Party. If the Response Notice is delivered in accordance with clause (ii) or (iii) of the preceding sentence, the Response Notice shall also contain a brief description of the facts and circumstances supporting Seller’s claim that only a portion or no part of the Claimed Amount is owed to the Indemnified Party, as the case may be. Any part of the Claimed Amount that is not agreed to be owed to the Indemnified Party pursuant to the Response Notice (or the entire Claimed Amount, if Seller asserts in the Response Notice that no part of the Claimed Amount is owed to the Indemnified Party) is referred to herein as the “Contested Amount” (it being understood that the Contested Amount shall be modified from time to time to reflect any good faith modifications by the Indemnified Party to the Claimed Amount). If a Response Notice is not received by the Indemnified Party prior to the expiration of the Dispute Period, then Seller shall be conclusively deemed to have agreed that the full Claimed Amount is owed to the Indemnified Party.

(i) If Seller delivers a Response Notice to the Indemnified Party agreeing that the full Claimed Amount is owed to the Indemnified Party or Seller does not deliver a Response Notice during the Dispute Period, then: (A) the lesser of the Then Remaining Holdback Amount (as defined below) and the entire Claimed Amount shall be deducted from the Holdback Amount; and (B) if the Then Remaining Holdback Amount is less than the Claimed Amount, the Seller Members shall, within ten (10) Business Days following the earlier of the delivery of such Response Notice or the expiration of the Dispute Period, pay the amount of such shortfall to Purchaser. The “Then Remaining Holdback Amount” shall mean the amount by which the Holdback Amount exceeds the sum of all amounts previously deemed or determined to be due and owing to any Indemnified Party pursuant to this Article VI.

(ii) If Seller delivers a Response Notice to the Indemnified Party during the Dispute Period agreeing that less than the full Claimed Amount is owed to the Indemnified Party, then: (A) the lesser of the Then Remaining Holdback Amount and the entire Agreed Amount shall be deducted from the Holdback Amount; and (B) if the Then Remaining Holdback Amount is less than the Agreed Amount, the Seller Members shall, within ten (10) Business Days following the delivery of such Response Notice, pay the amount of such shortfall to Purchaser, subject to the limitations set forth in Section 6.4.

(d) Resolution of Contested Amounts.

(i) If Seller delivers a Response Notice to the Indemnified Party during the Dispute Period indicating that there is a Contested Amount, Seller and the Indemnified Party shall attempt in good faith to resolve the dispute related to the Contested Amount. If the Indemnified Party and Seller resolve such dispute, then their resolution of such dispute shall be binding on Seller, the Seller

Member and such Indemnified Party and a settlement agreement stipulating the amount owed to the Indemnified Party (the “Stipulated Amount”) shall be signed by the Indemnified Party and Seller. Upon execution of a settlement agreement in favor an Indemnified Party, (A) the lesser of the Then Remaining Holdback Amount and the entire Stipulated Amount shall be deducted from the Holdback Amount; and (B) if the Then Remaining Holdback Amount is less than the Stipulated Amount, the Seller Members shall, within ten (10) Business Days following the execution of such settlement agreement, or such shorter period of time as may be set forth in the settlement agreement, pay the amount of such shortfall to Purchaser, subject to the limitations set forth in Section 6.4.

(ii) If Seller and the Indemnified Party are unable to resolve the dispute relating to any Contested Amount during the thirty (30)-day period commencing upon the delivery of the Response Notice to the Indemnified Party, then either the Indemnified Party or Seller may submit the claim described in the Notice of Claim to arbitration to be settled by binding arbitration in New York, New York or San Francisco, California in accordance with the JAMS Comprehensive Arbitration Rules and Procedures then in effect. Arbitration will be conducted by one arbitrator, mutually selected by the Indemnified Party and Seller; provided, however, that if the Indemnified Party and Seller fail to mutually select an arbitrator within fifteen (15) days after such dispute is submitted to arbitration, then the arbitrator shall be selected by JAMS in accordance with its Comprehensive Arbitration Rules and Procedures then in effect. The parties agree to use commercially reasonable efforts to cause the arbitration hearing to be conducted within seventy-five (75) days after the appointment of the arbitrator, and to use commercially reasonable efforts to cause the decision of the arbitrator to be furnished within fifteen (15) days after the conclusion of the arbitration hearing. The arbitrator’s authority shall be confined to deciding: (a) whether the Indemnified Party is entitled to recover the Contested Amount (or a portion thereof), and the portion of the Contested Amount the Indemnified Party is entitled to recover; and (b) the non-prevailing party in the arbitration. The final decision of the arbitrator shall include the dollar amount of the award to the Indemnified Party, if any (the “Award Amount”), shall be furnished to Seller and the Indemnified Party in writing and shall constitute a conclusive determination of the issue(s) in question, binding upon Seller and the Indemnified Party. The non-prevailing party in any such arbitration shall pay the reasonable expenses (including attorneys’ fees) of the prevailing party, and the fees and expenses associated with the arbitration (including the arbitrators’ fees and expenses). If an Indemnified Party is found to be the prevailing party in any arbitration, the amount of the fees and expenses of such Indemnified Party payable by the non-prevailing party pursuant to the immediately preceding sentence shall be added to the Award Amount. The non-prevailing party shall be determined solely by the arbitrator. Upon determination of an Award Amount in accordance with this Section 6.6(d): (A) the lesser of the Then Remaining Holdback Amount and the entire Award Amount shall be deducted from the Holdback Amount; and (B) if the Then Remaining Holdback Amount is less than the Award Amount, the Seller Members shall, within ten (10) Business Days following the delivery of the final decision of the arbitrator (or such shorter period as may be set forth in such final decision), pay the amount of such shortfall to Purchaser, subject to the limitations set forth in Section 6.4.

(e) Holdback Release.

(i) No later than the Holdback Release Date, Purchaser shall reasonably and in good faith determine the aggregate amount, as of the Holdback Release Date, of any Claimed Amounts and Contested Amounts associated with all claims contained in Notices of Claim that have not been finally resolved and paid prior to such date (the “Unresolved Claims”) and shall release the amount, if any, by which the Then Remaining Holdback Amount exceeds the aggregate amount of Unresolved Claims (the “Holdback Release Amount”) from the Holdback Amount and pay such amount to Seller in accordance with Section 1.2(b); provided, however, that if at such time there are any Unresolved Claims for which known or potential Damages cannot yet reasonably be estimated, the Holdback Release Amount shall be zero dollars ($0.00). The portion of the Then Remaining Holdback Amount retained by Purchaser pursuant to this Section 6.6(e)(i) is referred to as the “Retained Amount”.

(ii) Following the Holdback Release Date, within ten (10) Business Days after the final resolution of all Unresolved Claims and the delivery to all Indemnified Parties of all amounts to be delivered to such Persons with respect to all Unresolved Claims from the Retained Amount, if any, Purchaser shall release the amount, if any, by which the Retained Amount exceeds the aggregate of all amounts delivered to Indemnified Parties following the Holdback Release Date (the “Remaining Retained Amount”) from the Holdback Amount and pay such amount to Seller in accordance with Section 1.2(b); provided, however, that if the Remaining Retained Amount is less than the amount to be delivered to the Indemnified Parties with respect to such Unresolved Claim, then the Seller Members shall, within ten (10) Business Days following the resolution of such Unresolved Claims, pay the amount of such shortfall to Purchaser, subject to the limitations set forth in Section 6.4.

(f) Set-Off and Payment of Claimed Amounts. All payments by the Seller Members described in this Section 6.6(f) shall be subject to the limitations on indemnity set forth in Article VI.

(i) Purchaser shall have the right to set off and apply against any Earn-Out Payment an amount up to the amount by which all Claimed Amounts specified in any Notice of Claim delivered by Purchaser hereunder prior to the date of the Earn-Out Payment against which such set off is applied exceed the Then-Remaining Holdback Amount if, (x) such amount has not otherwise been paid to Purchaser by the Seller Members and (y) such amount continues to be owed to or recoverable by any Indemnified Party pursuant to this Article VI (the “Offset Amount”). Notwithstanding the foregoing, Purchaser shall first reduce the Claimed Amounts by any portion thereof recovered from any Collateral Source before calculating the Offset Amount in accordance with this Section 6.6(f)(i).

(ii) In the event Purchaser exercises its set off rights pursuant to this Section 6.6(f) and withholds an Offset Amount from any Earn-Out Payment, Purchaser shall notify Seller thereof in writing (the “Offset Notification”) no later than the day that such Earn-Out Payment is due. The Offset Notification shall set forth in reasonable detail the basis for Purchaser exercising its set off rights pursuant to this Section 6.6(f). Upon the final resolution of all claims for indemnification with respect to which an Offset Notification is delivered in accordance with the provisions of this Article VI, Purchaser shall cause Seller to be paid the amount, if any, by which the Offset Amount exceeds the amount of Damages to which Purchaser has been deemed or determined to be entitled in connection with such resolution pursuant to this Article VI.

Section 6.7 Exclusive Remedy. The parties agree that after the Closing, this Article VI will constitute the sole remedy of any Indemnified Party for recovery of Damages incurred or sustained by the Indemnified Parties pursuant to this Agreement. Purchaser and Seller agree to the matter specifically set forth on Schedule 6.7. Notwithstanding anything herein to the contrary, nothing in this Article VI shall (a) limit or in any way restrict the representations, warranties and covenants of (i) the Assignee under Section 1.8 of this Agreement, (ii) Seller or any Seller Member under Article IV of this Agreement, or (iii) Purchaser, Seller or any Seller Member under any Ancillary Agreement, or (b) limit the rights or remedies of Purchaser or any other Indemnified Party with respect to equitable remedies for non-monetary damages, including specific performance, injunctive and other equitable relief.

Section 6.8 Authority of Seller. The Seller Members authorize, designate and appoint Seller to act as the sole and exclusive agent, attorney-in-fact and representative of each of the Seller Members to, and Seller is hereby authorized and directed to, take such actions and exercise such rights, power and authority as are authorized, delegated and granted to Seller under this Article VI, including

pursuant to Section 6.6, and to exercise such rights, power and authority as are incidental to the foregoing. Any such actions taken, exercises of rights, power or authority, and decision or determination made by Seller consistent therewith shall be absolutely and irrevocably binding on each of the Seller Members as if such Person personally had taken such action, exercised such rights, power or authority or made such decision or determination in such Person’s individual capacity.

Section 6.9 No Double Recovery. Notwithstanding anything to the contrary herein, no party shall be entitled to indemnification for Damages under any provision of this Agreement for any amount to the extent such party has previously been indemnified for Damages for such amount under any other provision of this Agreement.
