In the event Buyer objects to the Estimated Net Working Capital set forth on the Estimated Net Working Capital Statement, Buyer and the Company shall negotiate in good faith to resolve such objections prior to the Closing.

(b) Within ninety (90) calendar days following the Closing Date, Buyer shall cause to be prepared and delivered to the Sellers’ Representative (i) a Closing Date Balance Sheet, (ii) a statement (the “Net Working Capital Statement”) setting forth its calculation of the Closing Date Net Working Capital and the components and calculations thereof, by reference to the Closing Date Balance Sheet, and (iii) a statement (the “Net Working Capital Adjustment Statement”) setting forth the calculation of the amount by which the Closing Date Net Working Capital as shown on the Net Working Capital Statement either (A) exceeds the Estimated Net Working Capital (as such amount may be adjusted below, the “Net Working Capital Excess Amount”) or (B) is less than the Estimated Net Working Capital (as such amount may be adjusted below, the “Net Working Capital Deficiency Amount”).

(c) After receipt of the Net Working Capital Statement and the Net Working Capital Adjustment Statement, the Sellers’ Representative shall have thirty (30) calendar days to review the Net Working Capital Statement and the Net Working Capital Adjustment Statement. Buyer shall give, or cause to be given, to the Sellers’ Representative reasonable access to all documents and records of the Group Companies used in their preparation. Not later than thirty (30) calendar days following the date of receipt of the Net Working Capital Statement and the Net Working Capital Adjustment Statement, the Sellers’ Representative shall provide Buyer with a written notice (a “Working Capital Dispute Notice”) listing those items, if any, to which the Sellers’ Representative takes exception, which notice shall also (i) specifically identify, and provide a reasonably detailed explanation of, the basis upon which the Sellers’ Representative has delivered such list, including, without limitation, the applicable provisions of this Agreement on which the dispute set forth in such Working Capital Dispute Notice is based, (ii) set forth the amount of Closing Date Net Working Capital that the Sellers’ Representative has calculated based on the information contained in the Net Working Capital Statement, and (iii) specifically

identify the Sellers’ Representative’s proposed adjustment(s). Unless the Sellers’ Representative delivers the Working Capital Dispute Notice to Buyer setting forth the specific items disputed by the Sellers’ Representative on or prior to the thirtieth (30th) day following the Sellers’ Representative’s receipt of the Net Working Capital Statement and the Net Working Capital Adjustment Statement, the Sellers’ Representative on behalf of the Sellers shall be deemed to have accepted and agreed to the Net Working Capital Statement and the Net Working Capital Adjustment Statement and such statements (and the calculations contained therein) shall be final, binding and conclusive. If the Sellers’ Representative timely provides Buyer with a Working Capital Dispute Notice, the Sellers’ Representative and Buyer shall, within fifteen (15) days following receipt of such Working Capital Dispute Notice by Buyer (the “Resolution Period”), attempt to resolve their differences with respect to the items specified in the Working Capital Dispute Notice (the “Disputed Items”), and all other undisputed items (and all calculations relating thereto) shall be final, binding and conclusive. Any written resolution by the Sellers’ Representative and Buyer during the Resolution Period as to any Disputed Items shall be final, binding and conclusive.

(d) If the Sellers’ Representative and Buyer do not resolve all Disputed Items by written resolution by the end of the Resolution Period, then all Disputed Items remaining in dispute shall be submitted within fifteen (15) days following the expiration of the Resolution Period to Deloitte LLP (the “Neutral Arbitrator”); provided that if at such time either the Sellers’ Representative or Buyer shall discover a bona fide conflict with respect to the Neutral Arbitrator or the Neutral Arbitrator resigns or expressly states its refusal for any reason to resolve the Disputed Items in accordance with this Section 2.6, the Parties shall submit the matter to another independent accounting firm of international reputation reasonably acceptable to both the Sellers’ Representative and Buyer to resolve the remaining matters in dispute, and such firm shall be the Neutral Arbitrator for all purposes of this Section 2.6(d). The Neutral Arbitrator shall act as an arbitrator to determine only those Disputed Items remaining in dispute, consistent with this Section 2.6, and shall request a statement from each of the Sellers’ Representative and Buyer regarding such remaining Disputed Items. The Neutral Arbitrator shall consider only those Disputed Items that the Sellers’ Representative on the one hand and Buyer on the other hand are unable to resolve. In resolving any disputed item, the Neutral Arbitrator may not assign a value to any item greater than the greatest value for such item claimed by any Party or less than the smallest value for such item claimed by any Party. The scope of the disputes to be arbitrated by the Neutral Arbitrator is limited to whether the preparation of the Net Working Capital Statement and the Net Working Capital Adjustment Statement were done in accordance with this Agreement, and whether there were mathematical errors in the preparation of the Net Working Capital Statement and the Net Working Capital Adjustment Statement, and the Neutral Arbitrator is not to make any other determination. All fees and expenses relating to the work, if any, to be performed by the Neutral Arbitrator shall be allocated between the Sellers’ Representative and Buyer in the same proportion that the aggregate amount of the Disputed Items so submitted to the Neutral Arbitrator that is unsuccessfully disputed by such Party (as finally determined by the Neutral Arbitrator) bears to the total amount of such Disputed Items so submitted by such Party. In addition, the Parties shall give the Neutral Arbitrator access to all documents, records and employees as reasonably necessary to perform its function as arbitrator. The Neutral Arbitrator shall deliver to the Sellers’ Representative and Buyer a written determination (such determination to include a work sheet

setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Neutral Arbitrator by the Sellers’ Representative and Buyer) of the Disputed Items submitted to the Neutral Arbitrator within thirty (30) days following receipt of such Disputed Items (or as soon thereafter as practicable), which determination shall be final, binding and conclusive, and judgment may be entered on the award.

(e) The final, binding and conclusive Net Working Capital Statement and Net Working Capital Adjustment Statement, in each case, based either upon agreement by the Sellers’ Representative and Buyer, the written determination delivered by the Neutral Arbitrator in accordance with this Section 2.6 or the Sellers’ Representative’s failure to notify Buyer, in accordance with this Section 2.6, of its objections to either the Net Working Capital Statement or the Net Working Capital Adjustment Statement (or any calculations contained therein) shall be the “Conclusive Net Working Capital Statement” and the “Conclusive Net Working Capital Adjustment Statement,” respectively. If either the Sellers’ Representative or Buyer fails to submit a statement regarding any Disputed Items submitted to the Neutral Arbitrator within the time determined by the Neutral Arbitrator or otherwise fails to give the Neutral Arbitrator access as reasonably requested, then the Neutral Arbitrator shall render a decision based solely on the evidence timely submitted and the access afforded to the Neutral Arbitrator by the Sellers’ Representative and Buyer.

(f)(i) Buyer shall pay an aggregate amount, if any, equal to the Net Working Capital Excess Amount, if any, set forth on the Conclusive Net Working Capital Adjustment Statement, which amount shall be paid to the Sellers or (ii) the Sellers’ Representative shall instruct the Escrow Agent to release to Buyer from the Escrow Account an amount equal to the Net Working Capital Deficiency Amount, if any, set forth on the Conclusive Net Working Capital Adjustment Statement. Any required payment under this Section 2.6(f) shall be paid on the third (3^rd) Business Day following the determination of the Conclusive Net Working Capital Statement by (x) check or wire transfer of immediately available funds to each Seller of such Seller’s portion of such amount as set forth on Exhibit 2.3(c) (in the case of a Net Working Capital Excess Amount), or (y) wire transfer to such bank account or accounts as Buyer (in the case of a Net Working Capital Deficiency Amount) may specify. Any Net Working Capital Excess Amount shall be deemed to be an increase in the Transaction Consideration and any Net Working Capital Deficiency Amount shall be deemed to be a decrease in the Transaction Consideration for purposes of this Agreement. In the event the Escrow Amount is insufficient to satisfy any obligations to pay Buyer pursuant to this Section 2.6(f), Buyer shall have the right (in addition to any other rights or remedies available to Buyer under law), but not the obligation, to withhold and off-set such amount from the Subsequent Consideration payments, if any.

2.7. Escrow Amount.

(a) Escrow Amount. At the Closing, $500,000 of cash and 185,687 shares of Buyer Common Stock (together, the “Escrow Amount”) shall be deposited into an escrow account (the “Escrow Account”) established with ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ Bank, National Association (the “Escrow Agent”) to be held by the Escrow Agent, pursuant to the terms of the escrow agreement attached as Exhibit B hereto (the “Escrow Agreement”), to serve as a source of payment for any amount due to Buyer for any claim for Damages for which any Buyer Indemnified Party is entitled to recovery pursuant to Article VII and amounts payable to Buyer

pursuant to Section 2.6(f). In connection with such deposit of the Escrow Amount into the Escrow Account with the Escrow Agent, each Seller shall be deemed to have received and deposited with the Escrow Agent such Seller’s pro-rata interest in the Escrow Account as determined as of the Closing by reference to Exhibit 2.3(c), without any act of such Stockholder.

(b) Release of Escrow Amount. Promptly following the Escrow Expiration Date, the Escrow Agent shall distribute to the Sellers’ Representative, who shall proceed to distribute to the Sellers in accordance with the percentage amounts to which each Seller is entitled under this Agreement and the Escrow Agreement, as set forth on Exhibit 2.3(c), the Escrow Amount then remaining in the Escrow Account (including accrued interests and other income) to such accounts designated by the Sellers minus the aggregate dollar amount of claims for Damages made by all Buyer Indemnified Parties pursuant to Article VII hereof (the “Aggregate Outstanding Claims”) which are then outstanding and unresolved (such amount of the retained Escrow Amount, as it may be further reduced after the Escrow Expiration Date by distributions to the Sellers’ Representative as set forth below and recoveries by the Buyer Indemnified Parties pursuant to Article VII hereof and the Escrow Agreement, the “Retained Escrow Amount”). For purposes of clarification, in the event that the amount of the Aggregate Outstanding Claims exceeds the remaining Escrow Amount, all the remaining Escrow Amount shall be retained in the Escrow Account as the Retained Escrow Amount. In the event and to the extent that after the Escrow Expiration Date any outstanding claim made by any Buyer Indemnified Party pursuant to Article VII hereof is resolved against such Buyer Indemnified Party, the Escrow Agent shall distribute to the Sellers’ Representative, who shall proceed to distribute to the Sellers in accordance with the percentage amounts to which each Seller is entitled under this Agreement and the Escrow Agreement, as set forth on Exhibit 2.3(c), to such accounts designated by the Sellers an aggregate amount of the Retained Escrow Amount equal to the amount of the outstanding claim resolved against such Buyer Indemnified Party; provided, however, that such distribution shall only be made to the extent that the Retained Escrow Amount remaining after such distribution would be sufficient to cover the amount of the Aggregate Outstanding Claims that are still unresolved at such time. In the event and to the extent that after the Escrow Expiration Date any outstanding claim made by any Buyer Indemnified Party pursuant to Article VII hereof is resolved in favor of such Buyer Indemnified Party, such Buyer Indemnified Party shall be entitled to recover pursuant to Article VII hereof an amount equal to the amount of the outstanding claim resolved in favor of such Buyer Indemnified Party.

(c) Escrow Agent Fees and Expenses. Any administrative fees and expenses of the Escrow Agent shall be paid by Buyer. During the period in which the Escrow Amount (including any Retained Escrow Amount) is retained in the Escrow Account, all interest or other income earned from any investment of the Escrow Amount (the “Escrow Earnings”) shall be retained as additional amounts in the Escrow Account.

(d) Per Share Price. Any shares of Company Common Stock used to satisfy any claims made against the Escrow Account, or otherwise released from the Escrow Account, shall be valued at the Per Share Price.

2.8. Sellers’ Representative.

(a) Appointment. As used in this Agreement, the term “Sellers’ Representative” shall mean Sofinnova Capital V FCPR, or any Person appointed as a successor Sellers’ Representative pursuant to Section 2.8(b) hereof. Sofinnova Capital V FCPR hereby accepts his, her or its appointment as the initial Sellers’ Representative. Effective upon the Closing, without any further action by any other Person, the Sellers’ Representative shall be appointed and constituted in respect of each Seller, as his, her or its agent, to act in his, her or its name, place and stead, as such Seller’s attorney-in-fact, as more fully set forth in Section 2.8(c).

(b) Election and Replacement. From and after the Closing Date until the date when all obligations under this Agreement have been discharged (including all indemnification obligations under Article VII hereof), the Sellers who are entitled to receive in excess of 50% of the Transaction Consideration (the “Majority”), may, from time to time upon written notice to the Sellers’ Representative and Buyer, remove any Sellers’ Representative (including any appointed by Buyer as provided below) or appoint a new Sellers’ Representative to fill any vacancy created by the death, incapacitation, resignation or removal of any Sellers’ Representative. In the event of a vacancy, the Sellers will promptly appoint a successor Sellers’ Representative hereunder. A copy of any appointment by the Majority of any successor Sellers’ Representative shall be provided to Buyer promptly after it shall have been effected.

In connection with the investigation by Buyer of the Company, Buyer has received from the Sellers or the Company certain projections, forward-looking statements and other forecasts and certain business plan information. Buyer acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that Buyer is familiar with such uncertainties and that Buyer is taking full responsibility for making their own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to them. Accordingly, Buyer acknowledges that the Sellers and the Company make no representation or warranty with respect to such estimates, projections, forecasts or plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans) and the Buyer has not relied on any such estimates, projections, forecasts or plans.

5.10. Buyer Common Stock. The shares of Buyer Common Stock included in the Share Consideration, when issued to the Sellers in accordance with the terms and conditions of this Agreement, will be duly authorized and validly issued, fully paid and nonassessable.

(b) At or prior to the Closing, Buyer shall purchase a six (6) year non-cancellable “tail” prepaid directors’ and officers’ liability insurance policy covering the Covered Persons, which provides at least the same coverage and amounts and containing terms and conditions which are no less favorable to the Covered Persons than the policies maintained as of the date hereof (the “D&O Tail”), effective as of the Closing.

6.9. Tax Matters.

(a) The Parties shall cooperate fully, as and to the extent reasonably requested by any of them, in connection with the filing of Tax Returns pursuant to this Agreement and any audit, litigation or other proceeding with respect to Taxes.

The Buyer agrees to use commercially reasonable efforts to use any available Tax credit that may reduce Pre-Closing Taxes consistent with Applicable Law.

(b) Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated by this Agreement (including Italian Tax on Financial Transactions pursuant to article 1, par. 491 of law 228 of December 24, 2012), if any, shall be borne and paid by Buyer. Buyer shall prepare and timely file all Tax Returns required to be filed in respect of

any such charges. For avoidance of doubt, the Parties hereby expressly agree and acknowledge that this provision shall not be applicable to any capital gain tax possibly due under any Applicable Law in connection with this Agreement, it being understood that such possible capital gain tax, if due, shall be solely and entirely borne by the Sellers.

6.10. Development and Commercialization of the Development Products.

(a) Buyer may direct, modify and terminate the clinical development or commercialization of any Development Product or the Development Compound or any products related thereto at any time, based upon its assessment, in its sole discretion, due to scientific, technical, regulatory or commercial reasons, including (a) safety or efficacy concerns, including adverse events of any Development Product or the Development Compound, (b) concerns relating to the present or future marketability or profitability of any Development Product or the Development Compound, (c) reasons related to Intellectual Property coverage of any Development Product or the Development Compound or (d) existing and anticipated competition that renders the clinical development or commercialization of any Development Product or the Development Compound no longer commercially practicable.

(c) Subject to Section 6.10(a), following the Closing, Buyer shall use commercially reasonable efforts to achieve each of the Milestones and to develop and commercialize the Development Compound in the United States. Buyer agrees that it will not, and will not permit its Affiliates (including after the Closing, the Group Companies) to, take any action with the primary intent of preventing or materially delaying the achievement of any Milestone.

(d) Buyer shall cause the Company to comply with all of its obligations, and cause the Company to use commercially reasonable efforts to enforce its rights, under the Collaboration and License Agreement and the Group Companies’ agreements with Advenchen Laboratories, LLC.

The right to indemnification or other remedy based on the representations, warranties, covenants and agreements herein shall not be affected by any investigation conducted with respect to, or any knowledge (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or agreement.

7.2. Indemnification.

(a)(i) Subsequent to the Closing, subject to the provisions of this Article VII, including the limitations described below in Section 7.5, each of Buyer and its respective Affiliates (including, after the Closing, the Group Companies) and each of its and their respective officers, directors, employees, stockholders and agents (the “Buyer Indemnified Parties”) shall be indemnified and reimbursed by the Sellers severally (in accordance with their respective Pro Rata Percentages) from and against any and all damage, claim, loss, cost, liability or expense, including interest, penalties, reasonable attorneys’ fees and expenses of investigation, response action, removal action or remedial action (collectively, “Damages”) incurred by such Buyer Indemnified Party that arise out of (v) any breach of any representation or warranty made by the Company in Article III; (w) any failure to perform any covenant or obligation made by the Company in this Agreement; (x) any Pre-Closing Taxes; or (y) any Buyer Indemnified Party’s enforcement of its rights under this Section 7.2(a)(i).

(ii) Subsequent to the Closing, subject to the provisions of this Article VII, including the limitations described below in Section 7.5, the Buyer Indemnified Parties shall be indemnified and reimbursed by the Sellers, severally and not jointly, from and against any and all Damages incurred by such Buyer Indemnified Party that arise out of (x) any breach of any representation or warranty made by such Seller in Article IV; (y) any failure to perform any covenant or obligation made by such Seller in or pursuant to this Agreement; or (z) any Buyer Indemnified Party’s enforcement of its rights under this Section 7.2(a)(ii).

(iii) Subsequent to the Closing, subject to the provisions of this Article VII, including the limitations described below in Section 7.5, Buyer shall indemnify and reimburse each Seller and its respective Affiliates and each of its and their respective officers, directors, employees, stockholders and agents (the “Seller Indemnified Parties” and collectively with the Buyer Indemnified Parties, the “Covered Parties”) from and against any and all Damages asserted against, suffered, sustained, accrued or incurred by such Seller Indemnified Party arising out of (x) any breach of any representation or warranty made by Buyer in Article V; (y) any failure to perform any covenant or obligation made by Buyer in or pursuant to this Agreement; or (z) any Seller Indemnified Party’s enforcement of its rights under this Section 7.2(a)(iii).

(b) The term “Damages” as used in this Article VII is not limited to matters asserted by third parties against the Covered Parties, but includes Damages actually incurred or sustained by such persons in the absence of third-party claims, and payments by a Covered Party shall not be a condition precedent to recovery, and shall be net of any insurance proceeds or other recoveries actually received that relate to the event giving rise to such Damages. Notwithstanding the foregoing, the term “Damages” shall not include any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income, or loss of business reputation or opportunity, except, in each case, for any such damages awarded to a third party in third-party claims.

7.3. Notice of Claims. Any Covered Party seeking indemnification hereunder shall, within the relevant limitation period provided for in Section 7.1 above, give to the Party which is obligated pursuant to this Article VII to provide indemnification as set forth herein (the “Indemnifying Party”) a notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to any claims for indemnification hereunder and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the provision of this Agreement or any agreement, certificate or instrument executed pursuant hereto or in connection herewith upon which such claim is based; provided that a Claim Notice in respect of any action at law or suit in equity by or against a third Person as to which indemnification shall be sought shall be given promptly after the action or suit is commenced; and provided further that failure to give such notice shall not affect such Covered Party’s right to indemnification hereunder except to the extent the Indemnifying Party shall have been materially prejudiced by such failure.

7.4. Third Person Claims. If a claim by a third Person is made against a Covered Party, and if such party intends to seek indemnity with respect thereto under this Article VII, such Covered Party shall promptly notify the Indemnifying Party in writing of such claims, setting forth such claims in reasonable detail. The Indemnifying Party shall have twenty (20) days following receipt of such notice to deliver to the Covered Party a written acknowledgement that such claim is an indemnifiable claim under this Article VII, that it shall undertake, conduct and control (in accordance with the terms hereof), through counsel of their own choosing and at their own expense, the settlement or defense thereof, and the Covered Party shall cooperate with them in connection therewith; provided, that, the Covered Party may participate in such settlement or defense through counsel chosen by such Covered Party and paid at its own expense, provided further that, if in the reasonable opinion of counsel for Indemnifying Party, there is a reasonable likelihood of a conflict of interest between the Indemnifying Party and the Covered Party, the Indemnifying Party shall be responsible for reasonable fees and expenses of one counsel to such Covered Party in connection with such defense. The Covered Party shall not pay or settle any such claim without the consent of the Sellers’ Representative with respect to claims where the Sellers are the Indemnifying Party and Buyer where Buyer is the Indemnifying Party. If the Indemnifying Party does not deliver to the Covered Party a written acknowledgement that such claim is an indemnifiable claim under this Article VII within such twenty (20) days, the Covered Party shall have the right to undertake the defense, compromise or settlement of the claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement. The Indemnifying Party shall not, except with the consent of the Covered Party, enter into any settlement that is not exclusively monetary paid entirely by the Indemnifying Party and does not include as an unconditional term thereof the giving by the person or persons asserting such claim

to all Covered Parties of an unconditional release from all liability with respect to such claim or consent to entry of any judgment. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to control any claim relating to Taxes of Buyer or its Subsidiaries, or the Group Companies for any Tax period ending after the Closing Date and shall not be entitled to settle, either administratively or after the commencement of litigation, any claim for Taxes which could adversely affect the liability of Buyer or its Subsidiaries, or the Group Companies for Taxes for any Tax period (or portion thereof) after the Closing Date, without the prior written consent of Buyer.

7.5. Limitations on Indemnity; Payments Out of Subsequent Consideration.

(a) Notwithstanding anything expressed or implied in this Article VII to the contrary, no Covered Party shall be entitled to make a claim for indemnification pursuant to Sections 7.2(a)(i)(v), 7.2(a)(ii)(x) or 7.2(a)(iii)(x) of this Agreement unless and until the aggregate of all Damages suffered by such Covered Party hereunder exceeds $1,000,000 (the “Deductible Amount”), at which point the Covered Party shall only be entitled to indemnification for amounts in excess of the Deductible Amount. Notwithstanding the foregoing, no Deductible Amount shall apply to (i) the Company’s representations and warranties set forth in Sections 3.1, 3.2, 3.3, 3.4, 3.11 and 3.23 hereof (ii) any Seller’s representations and warranties set forth in Sections 4.1, 4.2, 4.7, 4.8, 4.9, 4.10, 4.11, and 4.12 hereof, or (iii) Buyer’s representations and warranties set forth in Sections 5.1, 5.2 and 5.7.

(b) In the event of a claim for indemnification or reimbursement under Section 7.2(a)(i), the amount of the related Damages (after taking into account the limitations of Section 7.5(a)) shall be paid pursuant to and solely by means of deductions, first, from the Escrow Account and then, to the extent that the amount of the Damages are in excess of the amount available in the Escrow Account or the Escrow Agreement has terminated pursuant to its terms, as an offset against the Subsequent Consideration payments, if any, when payable; provided that with respect to claims for indemnification pursuant to Section 7.2(a)(i)(v), Damages shall be indemnifiable up to an aggregate maximum amount of $20,000,000 (which amount shall include all deductions from the Escrow Account and offsets against Subsequent Consideration payments); provided, further, however, with respect to claims related to breaches of Seller’s representations and warranties set forth in Section 3.4, Damages shall be indemnifiable up to an aggregate maximum amount (after taking into account all other claims for indemnification under this Agreement) of up to the aggregate consideration paid by Buyer to the Sellers, and Buyer may seek recovery directly against each Seller up to an amount (after taking into account all other claims for indemnification under this Agreement) equal to the portion of the aggregate consideration paid by Buyer to such Seller pursuant to this Agreement.

(c) In the event of a claim for indemnification or reimbursement under Section 7.2(a)(ii), the amount of the related Damages (after taking into account the limitations of Section 7.5(a)) shall be paid directly from the applicable Seller. In addition, Buyer may choose to deduct from the Escrow Amount up to such Seller’s share of the Escrow Amount as set forth on Exhibit 2.3(c) or withhold from the Subsequent Consideration payable to such Seller, if any, up to such Seller’s share of the Subsequent Consideration as set forth on Exhibit 2.3(c). Each Seller’s liability for payments pursuant to Section 7.2(a)(ii)(x) shall be limited to an aggregate amount (after taking into account all other claims for indemnification under this Agreement) equal to the portion of the aggregate consideration received by Seller pursuant to this Agreement.

(d) In the event of a claim for indemnification or reimbursement under Section 7.2(a)(iii), the amount of the related Damages (after taking into account the limitations of Section 7.5(a)) shall be paid directly by Buyer. Buyer’s liability for payments pursuant to Section 7.2(a)(iii)(x) shall in no event exceed the Transaction Consideration that would have been paid absent such breach.

(e) Notwithstanding anything herein to the contrary, in all cases determining whether there has been a breach of a representation or warranty for purposes of Section 7.2(a)(i)(v), 7.2(a)(ii)(x) or 7.2(a)(iii)(x), or in determining the amount of any Damages with respect to such breach, such representations and warranties (other than the representations and warranties in Sections 3.6(x), 3.7, 3.9, 3.17 and 3.24) shall be read without regard to any materiality qualifier (including, without limitation, any reference to Material Adverse Effect) contained therein.

(f) To the extent permitted by Applicable Law, any payment made by a Person indemnifying a Covered Party pursuant to this Article VII shall be treated on the Parties’ Tax Returns as an adjustment to the Transaction Consideration for all Tax purposes.

(g) Any payment of Damages made pursuant to this Article VII shall be paid by the Indemnifying Party without reduction for any tax benefits available to the Covered Party. To the extent that the Covered Party recognizes tax benefits as a result of any payment of Damages made pursuant to this Article VII, the Covered Party shall pay the amount of such tax benefits (but not in excess of such payment of Damages made pursuant to this Article VII) to the Indemnifying Party as such tax benefits are actually recognized by the Covered Party. For this purpose, the Covered Party shall be deemed to recognize a tax benefit with respect to a taxable year if, and to the extent that, the Covered Party’s cumulative liability for Taxes through the end of such taxable year, calculated by excluding any Tax items attributable to the payment of Damages made pursuant to this Article VII from all taxable years, exceeds the Covered Party’s actual cumulative liability for Taxes through the end of such taxable year, calculated by taking into account any Tax items attributable to the payment of Damages made pursuant to this Article VII for all taxable years (to the extent permitted by relevant Tax law and treating such Tax items as the last items claimed for any taxable year).

7.6. Remedies. The remedies in this Article VII shall be the sole and exclusive remedies of the Parties with respect to any breach of the respective representations, warranties, covenants and agreements pursuant to this Agreement or otherwise arising out of this Agreement, regardless of the theory or cause of action pled, except for the remedies of specific performance, injunction and other equitable relief; provided, however, that no Party hereto shall be deemed to have waived any rights, claims, causes of action or remedies if and to the extent actual fraud is proven on the part of a Party by another Party hereto or such rights, claims, causes of action or remedies may not be waived under Applicable Law.

Any Party may, from time to time, by notice pursuant to this Section 8.2, designate any other address to which any such notice to such Party shall be sent; provided that any such notice shall be deemed to have been delivered upon receipt.

8.3. Choice of Law. This Agreement shall be construed, interpreted and the rights of the Parties determined in accordance with the laws of the State of New York, as applied to agreements among New York residents entered into and wholly to be performed within the State of New York (without reference to any choice of law rules that would require the application of the laws of any other jurisdiction).

8.4. Entire Agreement; Amendments and Waivers. This Agreement, together with the other documents and instruments referred to herein and all exhibits and schedules hereto, constitutes the entire agreement among the Parties pertaining to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties. This Agreement may be amended or modified only by a written agreement executed and delivered by duly authorized officers of Buyer and the Sellers’ Representative. This Agreement may not be modified or amended except as provided in the immediately preceding sentence and any purported amendment by any Party or Parties effected in a manner which does not comply with this Section 8.4 shall be void. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

8.5. Counterparts. This Agreement may be executed by facsimile and in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

8.6. Severability. If any provision of this Agreement is deemed or held to be illegal, invalid or unenforceable, this Agreement shall be considered divisible and inoperative as to such provision to the extent it is deemed to be illegal, invalid or unenforceable, and in all other respects this Agreement shall remain in full force and effect; provided, however, that if any provision of this Agreement is deemed or held to be illegal, invalid or unenforceable the Parties agree to replace such illegal, invalid or unenforceable provision with a provision that is legal, valid and enforceable that achieves the original intent of the Parties as closely as possible. Further, should any provision contained in this Agreement ever be reformed or rewritten by any judicial body of competent jurisdiction, such provision as so reformed or rewritten shall be binding upon all Parties hereto.

8.7. Headings. The headings of the Articles and Sections herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

8.8. Schedules. The schedules and the exhibits referenced in this Agreement are a material part hereof and shall be treated as if fully incorporated into the body of the Agreement.

8.9. No Third Party Beneficiaries. Except as provided in Section 6.8, nothing expressed or referred to in this Agreement shall be construed to give any Person other than the Parties to this Agreement (and their successors and assigns) any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

8.10. Specific Performance. The Parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the Parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity without the necessity of demonstrating the inadequacy of monetary damages or posting bond with respect thereto.

8.11. No Strict Construction. The Parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

8.12. Expenses. Except as otherwise specifically provided in this Agreement, (a) Buyer shall pay its own fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby, (b) the Sellers shall pay their own fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby, and (c) the aggregate Transaction Expenses of the Group Companies due and payable prior to the Closing which remain unpaid at the Closing shall be paid by Buyer.

8.13. Arbitration.

(a) Each of the Parties agrees that any claims, disputes or disagreements arising under, or in connection with this Agreement including without limitation the construction, performance or breach of this Agreement will be referred exclusively to, and shall be finally settled by, a tribunal of arbitrators which will apply the Rules of the International Chamber of Commerce (ICC) which are deemed to form part of this Agreement.

(b) There shall be three arbitrators, one selected by the party initiating the arbitration (either Sellers’ Representative on behalf of Sellers or Buyer, as applicable) in the request for arbitration, the second selected by mutual agreement of the other party (either Sellers’ Representative on behalf of Sellers or Buyer, as applicable) within 20 days of the delivery of the request for arbitration, and the third (who shall act as chairperson of the arbitration tribunal) selected by the two party appointed arbitrators within 20 days of the selection of the second arbitrator. In the event that the respondent fails to select an arbitrator, or if the two party appointed arbitrators are unable or fail to agree upon the third arbitrator, the International Court of Arbitration of the International Chamber of Commerce shall designate the remaining arbitrator(s) required to comprise the tribunal. The claimant in the arbitration shall provide a copy of the request for arbitration to the respondent at the time such request is submitted to the Secretariat of the International Chamber of Commerce.

(c) The place of arbitration shall be London, United Kingdom. The language of the arbitral proceedings and of all submissions and written evidence shall be English; provided, however, that a Party, at its expense, may provide for translation or simultaneous interpretation into a language other than English.

(d) The arbitrators shall issue an award within nine months of the submission of the request for arbitration of any dispute.

(e) It is expressly understood and agreed by the parties that the rulings and award of the tribunal shall be conclusive and binding on the parties, their successors and permitted assigns. Judgment on the award rendered by the tribunal may be entered in any court having jurisdiction thereof.

(f) The parties agree that any arbitration shall be conducted in a confidential manner. The parties shall (i) not publicly disclose any information regarding the arbitration or any award issued in the arbitration, except as may be required by Applicable Law; and (ii) keep all material used or exchanged in the arbitration confidential and agree that any such material shall be used solely for the purposes of the arbitration, and shall not be used for any business, commercial, competitive or other purpose.

(g) The party that does not prevail in the arbitration proceeding shall pay the arbitrator’s fees and any administrative fees of arbitration.
