14

Objection”). The Notice of Objection shall specify which Final Statement(s) are being disputed and describe in reasonable detail the basis for such disputes.

(c)If the Shareholders do not deliver a Notice of Objection within the time limited therefor, then the Final Statements will be conclusive, final and binding in their entirety on all of the parties. If the Shareholders deliver a Notice of Objection with respect to one or more Final Statements in accordance with Section 2.4(b), then (i) the Final Statement(s) not subject to the Notice of Objection shall be conclusive, final and binding with respect to those items that are not objected to by the Shareholders in the Notice of Objection, (ii) the Shareholders and the Purchaser shall attempt to resolve such disputed items, and (iii) to the extent that the Shareholders and the Purchaser are unable to resolve any such disputes, the items set forth in the Notice of Objection shall be resolved in accordance with the procedures set forth in Section 2.4(d) below.

(d)In the event that the Purchaser and the Shareholders are unable to resolve the disputed items within |||||||||| |||||||||| days after delivery of the Notice of Objection, either the Purchaser or the Shareholders may demand that such disputed items be referred to an accounting firm mutually agreed by the Shareholders and the Purchaser that is not the accounting firm for any of the Company, the Purchaser or any of the Shareholders (the “Accounting Firm”) to finally resolve such disputed items. The Accounting Firm shall act as an expert and not as an arbitrator to determine only the disputed items, and the determination of each disputed item shall be within the range established by the Final Statements and the Notice of Objection, if any. The determination of the Accounting Firm shall be made as promptly as possible and shall be final and binding upon the parties. Each party hereto shall be permitted to submit such data and information to the Accounting Firm as such party deems appropriate. The fees and expenses of the Accounting Firm incurred in resolving the disputed matter shall be borne by each of the Purchaser, on the one hand, and the Shareholders, on the other hand, in proportion to the difference between their respective position(s) on the matter(s) under dispute and the ultimate determined amount.

15

herein to the “Closing Purchase Price” shall mean and refer to the Final Purchase Price, as so determined and adjusted.

(b)General. Neither Purchaser nor any of its Affiliates shall assume any Company Option that is outstanding immediately prior to the Closing, whether or not then exercisable. For the avoidance of doubt, to the extent any holder of Company Options exercises such Company Options prior to the Closing, such holder shall be treated as a Shareholder hereunder with respect to the shares of Company Capital Shares issued in respect of such exercise (which shares shall be deemed issued and outstanding as of immediately prior to Closing for all purposes of this Agreement, unless sold or otherwise transferred prior to the Closing).

Section 2.6Contingent Consideration.

(a)Milestone Payments. Purchaser shall pay to the Shareholders, in accordance with this Section 2.6, the following payments (each, a “Milestone Payment”) upon achievement of the following milestones (each, a “Milestone”):

(i)an amount equal to |||||||||||| ||||||||||||(the “First MilestonePayment”) upon the Company receiving notification from the FDA of the designation of the GLyPharma Product as an orphan drug as documented under 21 C.F.R. §316.24(c) (the “First Milestone”); provided, however, that if the FDA does not deliver a designation of the GLyPharma Product as an orphan drug as provided above prior to the first patient dosing with the GLyPharma Product in a Pivotal Trial as set forth in Section 2.6(a)(iii), the First Milestone Payment shall be forfeited;

(ii)an amount equal to ||||||||||||| |||||||||||||(the “Second MilestonePayment”) upon the Therachon Board’s decision to proceed to a Pivotal Trial of the GLyPharma Product, irrespective of indication. Such decision shall be made as early as practicable on a diligent and timely basis by the Therachon Board following the completion of the planned phase 2a clinical trial of the GLyPharma Product in short bowel syndrome patients dependent on total parenteral nutrition and short bowel syndrome intestinal insufficiency patients and shall depend on the acceptable safety/tolerability/efficacy results of such trials and must be corroborated by no regulatory objections from either the FDA or EMA (the “Second Milestone”); and

(iii)an amount equal to ||||||||||||| |||||||||||||(the “Third MilestonePayment” and together with the Second Milestone Payment, each an “Additional MilestonePayment”) upon the first patient dosing with the GLyPharma Product in a Pivotal Trial, even if deferred pending other studies (the “Third Milestone” and together with the Second Milestone, each an “Additional Milestone”).

16

For the avoidance of doubt, each Milestone may only be achieved one time and each Milestone Payment may only be paid one time, if at all.

(b)Payment Procedure for First Milestone. Upon the achievement of the First Milestone, the First Milestone Payment shall be payable in shares of First Milestone Shares at a price per share equal to either (a) the Private FMV of Therachon Preferred Shares if the Therachon IPO has not occurred as of such payment or (b) the Public FMV of Therachon Ordinary Shares if the Therachon IPO has occurred as of such payment. In the event that the First Milestone Payment is due pursuant to Section 2.6(a)(i), then Therachon shall, as soon as practicable and in no event more than thirty (30) days following such First Milestone Payment becoming due, deliver or cause to be delivered to the Shareholders, such number of shares of First Milestone Shares.

(c)Payment Procedure for Additional Milestones. Upon the achievement of the Additional Milestone, the Additional Milestone Payments shall be payable, at Therachon’s sole and absolute discretion, in either cash or shares of Additional Milestone Shares, except that the Additional Milestone Payments shall include at least || ||of the value of such milestone payment in Additional Milestone Shares, at a price per share equal to either (a) if the Therachon IPO has not occurred as of such payment the greater of (x) the Private FMV of Therachon Preferred Shares or ||||||| ||||||| or (b) the Public FMV of Therachon Ordinary Shares if the Therachon IPO has occurred as of such payment. In the event that an Additional Milestone Payment is due pursuant to Section 2.6(a)(ii) or (iii), then Therachon shall, as soon as practicable and in no event more than |||||| |||||| days following such Additional Milestone Payment becoming due, deliver or cause to be delivered to the Shareholders, such number of shares of Additional Milestone Shares and a sufficient amount of cash in U.S. dollars to be paid in connection with such Additional Milestone Payments by wire transfer of immediately available funds to an account designated by the Shareholders at least |||| |||| Business Days prior to the date of payment.

(d)Diligence. Purchaser shall, and shall cause its Affiliates to, (i) act in good faith and use Commercially Reasonable Efforts to achieve the Milestones, where “CommerciallyReasonable Efforts” means such commercially reasonable efforts as are typically used by a similarly situated pharmaceutical company in comparable circumstances for the development and commercialization of prescription pharmaceutical products of similar commercial potential at a similar stage in product lifecycle, taking into consideration the safety and efficacy of such product, its competitiveness compared to alternative third party products, the proprietary position of the product (including scope and duration of relevant patents), the scope, timing and likelihood of regulatory approval, the regulatory status of the product, whether the product is subject to a clinical hold, recall or market withdrawal, and the anticipated reimbursability and pricing of the product, and (ii) refrain from taking any action in bad faith or without reasonable basis which is intended to prevent, or the primary effect of which is to prevent, the realization of the achievement of any of the Milestones. Without restricting the generality of the foregoing, any failure of the Therachon Board to act in accordance with this Section 2.6(d) shall be deemed to be a breach of this Section 2.6(d) by Therachon.

(e)Milestone Prepayment; Form of Consideration. Notwithstanding anything to the contrary herein, upon the occurrence of an Acceleration Event, Therachon (A) in the case of an Acceleration Event contemplated by paragraphs (a) or (b) of the definition of “Acceleration Event” (hereinafter referred to as a “Therachon-level Acceleration Event”), may elect to make any

17

remaining Milestone Payments to the Shareholders either prior to or when the relevant Milestone has been achieved, and (B) in the case of an Acceleration Event contemplated by paragraph (c) of the definition of “Acceleration Event” (hereinafter referred to as a “GLyPharma-level AccelerationEvent”), shall make any remaining Milestone Payments to the Shareholders on or prior to the occurrence the Acceleration Event. The Purchaser shall provide written notice to the Shareholders in the case of a Therachon-level Acceleration Event at least 10 days prior to the occurrence of a Therachon-level Acceleration Event, whether (i) the Purchaser elects to make one or more remaining Milestone Payments in connection therewith or (ii) the Purchaser elects to make one or more remaining Milestone Payments only following the achievement of such Milestones. The Purchaser shall provide written notice to the Shareholders in the case of a GLyPharma-level Acceleration Event at least |||| |||| prior to the occurrence of a GLyPharma-level Acceleration Event, indicating that the conditions for a GLyPharma-level Acceleration Event have been satisfied and that the Milestone Payments are being accelerated pursuant to this Section 2.6(e) upon the closing of such transaction. Any such payment of Milestone Payments that are paid prior to being earned pursuant to this Section 2.6(e) is hereinafter referred to as the “MilestonePrepayment”. Any Milestone Prepayment shall be made in the same form (cash and shares) as contemplated by this Agreement as if the respective Milestones had been achieved immediately prior to the closing of such transaction; provided, however, that with respect to a GLyPharma-level Acceleration Event such Milestone Prepayment shall be paid in cash. The parties agree and acknowledge that any Milestone Prepayment shall be treated as a Milestone Payment for purposes of this agreement, and that upon any Milestone Prepayment, the Shareholders shall not be entitled to the equivalent Milestone Payments if such applicable Milestones are achieved. Therachon agrees that any sale or disposition of the GLyPharma Product that is not a GLyPharma-level Acceleration Event or a Therachon-level Acceleration Event, by it or its Affiliates, directly or indirectly, pursuant to an asset sale or sale of ||| ||| of the outstanding capital shares of the Company or any other Therachon Affiliates, prior to the earlier of (A) the date on which the Therachon Board decides not to proceed to a Pivotal Trial of the GLyPharma Product, irrespective of indication, and (B) the payment of the last Milestone Payment provided herein, shall require the purchaser of the GLyPharma Product to assume and be responsible for the obligation to pay the Milestone Payments to Sellers if and when earned, with consideration of equivalent value to those contemplated herein. Therachon and Sellers agree that any merger or consolidation that constitutes a Therechon-level Acceleration Event but that does not result in a Milestone Prepayment, shall require that the prospective purchaser assume the obligation to make the Milestone Payments to the Sellers when such Milestone has been achieved as contemplated by this Agreement; provided, however, that any such Additional Milestone Shares that are earned following such transaction shall be the same type of securities as were granted to the holders of Therachon Series A Preferred Shares, if any; provided, further, that the total consideration payable to Sellers shall be comprised of the same ratio of cash and stock as were paid to the holders of Therachon Series A Preferred Shares.

(f)Return of Rights to GLyPharma if Cessation of Development. In the event that Therachon’s Board decides, in good faith, to cease or discontinue all development activities with regard to the GLyPharma Product prior to the Second Milestone Payment, Therachon shall cause its Affiliates, including the Company, to, (i) assign all rights, title and interest in and to the GLyPharma Product held by it or its Affiliates, including under the License Agreement, to the Shareholders or such entity as the Shareholders may direct, and (ii) grant Shareholders or such entity as they may direct, by transfer or assignment, all right, title and interest in and to: (A) all data relating to non-clinical and clinical studies conducted on, and all filings made with regulatory agencies

18

specifically with respect to, the GLyPharma Product; and (ii) any regulatory approvals and regulatory documentation specifically relating to the GLyPharma Product. In consideration of the grant and transfer of rights by Therachon pursuant to this section, Shareholders shall pay to Therachon a |||||||||||| |||||||||||| royalty on all net sales of the GLyPharma Product sold by the Shareholders, its affiliates, licensees, sublicensees or any other entity to which the Shareholders transfer the GLyPharma Product, up to an amount equal to ||| ||| of the documented development costs incurred by Therachon after the Closing Date with regard to the GLyPharma Product (excluding, for greater certainty, any such amounts as are paid for through Net Working Capital held by the Company immediately following the Closing). To avoid doubt, this section is solely applicable if a decision is made to cease or not continue development activities prior to payment of the Second Milestone Payment and shall not apply to any other milestone or Therachon Board decision.

Section 2.7No Further Ownership Rights in Company Capital Shares. From and after the Closing, the holders of shares of Company Capital Shares outstanding immediately prior to the Closing shall cease to have any rights with respect to such shares, except as otherwise provided for herein or by applicable Legal Requirements.

Section 2.8Lost, Stolen or Destroyed Certificates. In the event that any Company Certificates shall have been lost, stolen or destroyed, the Purchaser shall cause to be paid in exchange for such lost, stolen or destroyed Company Certificates, upon the making of an affidavit of that fact by the holder thereof, such payment of consideration as set out on Schedule A; provided, however, that Purchaser may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Company Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Purchaser with respect to the Company Certificates alleged to have been lost, stolen or destroyed.

Section 2.9Taking of Necessary Action; Further Action. If at any time after the Closing Date any further action is necessary or desirable to carry out the purposes of this Agreement and to vest Purchaser with full right, title and possession to the Purchased Equity, the officers and directors of Purchaser and the Company are fully authorized in the name of their respective entities or otherwise to take, and will take, all such lawful and necessary action, so long as such action is not inconsistent with this Agreement.

Section 2.10Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) imposed on any Person with respect to the transactions contemplated by this Agreement shall be borne and paid by such Person.

Section 2.11Escrow. On the Closing Date, Purchaser shall deliver to the Escrow Agent, as a contribution to the Escrow Account, the Escrow Amount, which shall be available to compensate Purchaser (on behalf of itself or any other Purchaser Indemnified Persons) for Damages pursuant to the indemnification obligations of the Company and Shareholders set forth in Article VIII of this Agreement, the Escrow Agreement and pursuant to Section 2.4(e) for any Purchase Price Deficit. The Escrow Amount shall be held by the Escrow Agent in accordance with the terms of this Agreement and the terms of the Escrow Agreement. As promptly as practicable following the date that is 18 months following the Closing Date (the “Escrow Release Date”), the

Escrow Agent shall disburse to the Shareholders any amount then remaining in the Escrow Account less the portion of the Escrow Amount required to address (x) all unsatisfied or disputed claims for indemnification specified in any claim notice delivered to the Escrow Agent prior to the Escrow Release Date in accordance with Article VIII, and (y) any pending dispute with respect to the determination of Final Purchase Consideration which, if determined in favor of Purchaser in accordance with Section 2.4(e), would result in a Purchase Price Deficit. Any portion of the Escrow Amount held following the Escrow Release Date with respect to pending but unresolved claims for indemnification or a Purchase Price Deficit that is not awarded to Purchaser upon the resolution of such claims shall be disbursed within ||||| ||||| Business Days following final resolution of such claims to the Shareholders.

(b)Refunds or Credits. Purchaser shall be entitled to all Refundable Tax Credits and non-refundable Tax credits with respect to any period ending on or prior to the Closing Date.

(c)Tax Returns. Purchaser shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company for any taxable year or period that ends on or before the Closing Date that are due (including extensions) after the Closing Date and for any Straddle Period. Those Tax Returns will be prepared in accordance with the Company’s past practice unless Purchaser determines that past practice was not in accordance with applicable Legal Requirements. At least 30 days prior to the filing of each such Tax Return with respect to Pre-Closing Tax Periods or Straddle Periods, Purchaser shall provide copies of such Tax Return to the Shareholders for the Shareholders’ review and comment and Purchaser shall consider in good faith the Shareholders’ comments to such Tax Return.

The Shareholders agree (i) to retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Tax Authority, and (ii) to give Purchaser reasonable written notice prior to transferring, destroying or discarding any such books and records and, if Purchaser so requests, the Shareholders shall allow Purchaser to take possession of such books and records prior to such transfer, destruction or discarding.

(e)Contests. In the case of any notice of Tax deficiency, proposed Tax adjustment, Tax assessment, Tax audit, Tax examination or other administrative or court proceeding, suit, dispute or other claim with respect to Taxes (a “Tax Claim”) relating to any Tax period ending on or before the Closing Date that, if determined adversely to the Company would be grounds for a claim for indemnity pursuant to this Section 6.4, Purchaser shall upon receipt of such Tax Claim, promptly, but no later than 15 days, inform the Shareholders of such Tax Claim and the Shareholders (at their sole cost and expense) shall have the right to control the conduct of such Tax Claim and shall have the right to settle such Tax Claim; provided, however, (i) that Purchaser may fully participate in the dispute of such Tax Claim, (ii) the Shareholders shall keep Purchaser timely informed with respect to the commencement, status and nature of any such Tax Claim and (iii) the Shareholders shall not settle, compromise or dispose of any Tax Claim without the consent of Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed.

The failure by Purchaser to provide the notice contemplated by this Section 6.4(e) shall not affect the Shareholders’ indemnification obligations under Article VII.

(f)Adjustment to Consideration. Any indemnification payment under ArticleVIII shall, to the extent such payment can be properly so characterized under applicable Tax law, be treated as an adjustment to the consideration payable hereunder.

(g)Pre-Closing Tax Period Actions. No Purchaser Indemnified Person will: (i) file or amend any Tax Return of the Company with respect to any Pre-Closing Tax Period or Straddle Period or (ii) permit the Company to make any Tax election that has retroactive effect to any Tax Return for a Pre-Closing Tax Period or Straddle Period, in each case, except (x) as permitted by Section 6.4(c), or (y) with the prior written consent of the Shareholders (which will not be unreasonably withheld, conditioned or delayed).

(b)Acknowledgement of Scope. The Shareholders acknowledge that the restrictions contained in this Section 6.6 are reasonable and necessary to protect the legitimate interests of Purchaser and constitute a material inducement to Purchaser to enter into this Agreement and consummate the transactions contemplated by this Agreement. Without limiting Section 9.5, in the event that any covenant contained in this Section 6.6 should ever be adjudicated to exceed the time, geographic, product or service or other limitations permitted by Legal Requirements in any jurisdiction, then any court is expressly empowered and directed to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service or other limitations permitted by applicable Legal Requirements. The covenants contained in this Section 6.6 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

(c)Third Party Acquirer.

The applicable

55

Indemnified Person shall be entitled to be indemnified for the reasonable fees and expenses of counsel for any period during which the Indemnifying Person has not assumed the defense of any such Third Party Claim in accordance herewith. If the Indemnifying Person delivers a Defense Notice requesting to assume the defense of the Third Party Claim, and the Indemnified Person consents to such assumption, such Indemnified Person will cooperate with and make available to the Indemnifying Person such assistance and materials as the Indemnifying Person may reasonably request, all at the sole expense of the Indemnifying Person, and the Indemnified Person shall have the right at its expense to participate in the defense assisted by counsel of its own choosing.

If the fees and expenses of counsel to the Indemnified Person are determined to be recoverable Damages in accordance herewith, in no event shall the Indemnifying Persons be responsible for the fees and expenses of more than one counsel (in addition to any required local counsel).

(iii)The Indemnifying Party shall not be entitled to settle or compromise any Third Party Claim if it is otherwise not entitled to control the defense of such Third Party Claim. With respect to Third Party Claims which the Indemnifying Party is entitled to control the defense of, the Indemnifying Person shall not, without the prior written consent of the applicable Indemnified Person (i) settle or compromise a Third Party Claim or consent to the entry of any Proceeding which does not include an unconditional release by the claimant or plaintiff of such Indemnified Person from all liability in respect of the Third Party Claim; (ii) settle or compromise any Third Party Claim if the settlement imposes equitable remedies or other obligations on such Indemnified Person; or (iii) settle or compromise any Third Party Claim if the result is to admit civil or criminal liability or culpability on the part of such Indemnified Person. If the Indemnifying Person has not assumed the control of the defense of a Third Party Claim or is not entitled to control the defense of a Third Party Claim, the Indemnified Person shall have the right, subject to Section 8.4(b)(ii), to defend such Third Party Claim; provided, however, that the Indemnified Person shall not settle, compromise or discharge, or admit any liability with respect to, any such Third Party Claim without the prior written consent of the Indemnifying Person (such consent not to be unreasonably withheld, conditioned or delayed).

(c)Claims Against Shareholders.

(i)Upon receipt of a Claim Notice, the Shareholders or, in the case of a Claim Notice with respect to a Direct Shareholder Claim, the applicable Principal Shareholder, may object to any Claim Notice by delivering written notice to Purchaser, with a copy to the Escrow Agent, of the Shareholders’ objection or, in respect of a Direct Shareholder Claim, the applicable Principal Shareholder’s objection (the “ShareholderObjection Notice”). Such Shareholder Objection Notice must describe the grounds for such objection in reasonable detail.

56

(ii)If an Shareholder Objection Notice is not delivered by the Shareholders, or in the case of a Claim Notice with respect to a Direct Shareholder Claim, the Principal Shareholder, to Purchaser (with a copy of the Escrow Agent) within thirty (30) days after delivery by Purchaser of the Claims Notice, such failure to so object will be an irrevocable acknowledgment by the Shareholders that the Indemnified Persons are entitled to indemnification under Section 8.2 for the Damages sought pursuant to the Claim Notice in accordance with this Article VIII.

(iii)If Purchaser delivered the Claim Notice to the Escrow Agent and the Shareholders and no Shareholder Objection Notice was delivered to the Escrow Agent within forty-five (45) days of the delivery of the Claim Notice, or a Shareholder Objection Notice was delivered to the Escrow Agent within forty-five (45) days of the delivery of the Claim Notice, but such Shareholder Objection Notice states that it was, or admits liability, only with respect to a portion of the Damages claimed in the Claim Notice, the Escrow Agent will deliver to Purchaser as soon as practicable cash from the Escrow Fund having a value equal to (1) the amount of the Damages set forth in such Claims Notice, if no Shareholder Objection Notice was delivered to the Escrow Agent, or (2) the amount of the portion of the Damages set forth in such Claim Notice to which no objection was made, if a Shareholder Objection Notice was delivered to the Escrow Agent, except that, to the extent that the amount of the Damages set forth in the Claim Notice (or portion thereof) is an estimate, Purchaser (on behalf of itself or any other Indemnified Person) will not be so entitled to receive, and the Escrow Agent will not deliver, funds in respect of such portions of such estimated Damages unless and until the amount of such estimated Damages is finally determined.

(iv)If the Shareholders or, in the case of a Claim Notice with respect to a Direct Shareholder Claim the applicable Shareholder, objects in writing to any Claim Notice within forty-five (45) days after delivery of such Claim Notice, Purchaser and the Shareholders or the Principal Shareholder, as applicable, will attempt in good faith to agree upon the rights of Purchaser and the Shareholders with respect to each such claim. If Purchaser and the Shareholders or Shareholder, as applicable, should so agree, a memorandum setting forth such agreement will be prepared and signed by both parties. To the extent that an Indemnity Claim is recoverable from the Escrow Account pursuant to the terms of this Agreement, and Purchaser elects to recover from the Escrow Account such amounts, a copy of the memorandum setting forth the agreement will be delivered to the Escrow Agent. The Escrow Agent will be entitled to rely on any such memorandum and will distribute cash as soon as practicable from the Escrow Account in accordance with the terms thereof.

(v)If no such agreement can be reached after good-faith negotiation and after forty-five (45) days after delivery of a Shareholder Objection Notice, either Purchaser or the Shareholders or, in the case of an Indemnity Claim with respect to a Direct Shareholder Claim, the applicable Principal Shareholder, may refer the matter to arbitration for resolution in accordance with Section 9.6. If the amount of the Damages so determined is an estimate, then the amount the Damages will be required to be paid within ten days of the date that the amount of the Damages is finally determined.

57

Section 8.5No Right of Contribution. The Shareholders shall not make any claim for contribution from the Company with respect to any indemnity claims arising under or in connection with this Agreement to the extent that Purchaser, the Company or any Purchaser Indemnified Person is entitled to indemnification under Section 8.2(a) for such claim, and Shareholders hereby waive any such right of contribution from the Company it has or may have in the future.

Section 8.6Source of Recovery. Purchaser and the Shareholders hereby expressly acknowledge and agree that Purchaser shall have the right, but not the obligation, to receive payment for its Damages, as finally determined in accordance herewith and in accordance with the Proportionate Shares, against the Escrow Account or any Milestone Payment that may be or become due or that has been made, and with respect to Fundamental Representations and claims for indemnification under Section 8.2(b) only, directly against the Shareholders, (i) any and all Damages owed to any Purchaser Indemnified Person pursuant to this Article VIII (for greater certainty, subject to the limitations set out therein) and (ii) any and all amounts otherwise owed to the Purchaser or its Affiliates pursuant to this Agreement. In the event that Milestone Shares have been issued to the Shareholders as part of a Milestone Payment, for purposes of satisfying any indemnification claim by resort to the Milestone Shares, each Milestone Share shall be valued at a price per share (determined as of the business day immediately prior to the cancellation of such shares as provided below) equal to either (a) if the Therachon IPO has not occurred as of the date of the Claim Notice the greater of (x) the Private FMV of Therachon Preferred Shares or (y) ||| |||||| ||| or (b) the Public FMV of Therachon Ordinary Shares if the Therachon IPO has occurred as of the date of the Claim Notice. For the purpose of illustration, if a Purchaser Indemnified Person is owed ||||||||||| ||||||||||| in Damages, the Shareholders have been issued Milestone Shares, the Therachon IPO has occurred, and the Public FMV of Therachon Ordinary Shares is |||||||| |||||||| then Therachon shall be entitled to require the Shareholders to transfer to it free of charge and thereafter cancel ||| |||||| ||| Milestone Shares held by the Shareholders (in accordance with the Proportionate Shares) as satisfaction for such Damages for the matters specified in the Claim Notice. The details of any such payment, including whether Milestone Shares shall serve as satisfaction for Damages and the amount of Milestone Shares to be cancelled, shall be specified in the Claim Notice pursuant to Section 8.4(a). Upon the resolution of a dispute, whether through arbitration, agreement, settlement or otherwise, in favor of the Purchaser Indemnified Party in which Milestone Shares are to be cancelled as satisfaction for Damages, such Milestone Shares shall either (i) be automatically cancelled on the books and share ledger of Therachon without any further action by any party if the Therachon IPO has not occurred or (ii) Therachon shall provide instructions to its transfer agent to immediately cancel such shares on its books and share ledger if the Therachon IPO has occurred.

Section 8.7Effect of Investigation; Reliance. The right to indemnification, payment of Damages or any other remedy will not be affected by any investigation conducted, or any knowledge acquired (or capable of being acquired) at any time (except as expressly disclosed in this Agreement or the Company Disclosure Schedule as of the date hereof), whether before or after the execution and delivery of this Agreement, with respect to the accuracy or inaccuracy of or compliance with, any representation, warranty, covenant or agreement made by any party hereto. The waiver of any condition based on the accuracy of any such representation or warranty, or on the performance of or compliance with any such covenant or agreement, will not affect the right to indemnification, payment of Damages, or any other remedy based on any such representation,

58

warranty, covenant or agreement. No Indemnified Person shall be required to show reliance on any representation, warranty, certificate or other agreement in order for such Indemnified Person to be entitled to indemnification hereunder.

Section 8.8Seller Supermajority Powers and Responsibilities.

(a)Each Shareholder appoints the holders of a Proportionate Share constituting at least 2/3 of the aggregate of all Proportionate Shares (the “Seller Supermajority”) as such Shareholder’s mandataries with the powers and authority to act on behalf of all Shareholder as set forth in this Section 8.8, and the Seller Supermajority hereby accepts such appointment. The Seller Supermajority, acting together, shall be the exclusive mandataries for and on behalf of the Shareholders, and may bind all the Shareholders, to (1) authorize deliveries to Purchaser of cash or other property from the Escrow Account and legally bind each Shareholder to pay cash directly to Purchaser in satisfaction of claims asserted by Purchaser (on behalf of itself or any other Indemnified Person, including by not objecting to such claims), other than in connection with Direct Shareholder Claims; (2) object to such claims, other than in connection with Direct Shareholder Claims; (3) consent or agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with Legal Requirements with respect to, such claims, other than in connection with Direct Shareholder Claims; (4) take all actions necessary or appropriate in the judgment of the Seller Supermajority for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Person under any circumstance, other than in connection with Direct Shareholder Claims, (5) execute for and on behalf of each Shareholder any waiver or extension to this Agreement in connection with such claims, other than Direct Shareholder Claims. This appointment of mandatary is coupled with an interest and will be irrevocable and will not be terminated by any Shareholder or by operation of any Legal Requirement, and any action taken by the Seller Supermajority will be as valid as if such event had not occurred, regardless of whether or not any Shareholder or the Seller Supermajority will have received any notice thereof. The Seller Supermajority shall be the sole and exclusive means of asserting or addressing any of the above, and no Shareholder shall have any right to act on its own behalf with respect to any such matters, other than any claim or dispute against the Seller Supermajority. The Seller Supermajority agree to take such reasonable steps as are practicable to consult with the other Shareholders prior to taking any of the actions permitted to them under this Section 8.8. The Seller Supermajority agree to provide to the other Shareholders a summary of their acts and of all funds authorized by them to be disbursed from the Escrow Account pursuant to this Section 8.8, containing such details as are reasonably requested, upon reasonable request by the other Shareholders.

(b)Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Seller Supermajority that is within the scope of the Seller Supermajority’s authority under Section 8.8(a) shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all Shareholders and shall be final, binding and conclusive upon each of them. Each Indemnified Person and the Escrow Agent shall be entitled to rely upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Shareholder. Each Indemnified Person and the

59

Escrow Agent are unconditionally and irrevocably relieved from any liability to any person for any acts done by them in accordance with any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent or instruction of the Seller Supermajority.

(c)All expenses, if any, incurred by the Seller Supermajority in connection with the performance of their duties under this Section 8.8 (the “Representative Expenses”) will be borne and paid by the Shareholders according to their respective Proportionate Shares. Representative Expenses will be paid first out of amounts that would otherwise be distributed to the Shareholders in the custody of the Supermajority Shareholders and second directly by the other Shareholders. No bond will be required of the Seller Supermajority, and the Seller Supermajority will not receive any compensation for their services.

(d)The Seller Supermajority shall not be liable to any Shareholder for any act done or omitted hereunder as the Seller Supermajority while acting in good faith and any act done or omitted in accordance with the advice of counsel or other expert shall be conclusive evidence of such good faith. The Shareholders shall indemnify the Seller Supermajority and hold them harmless against the other Shareholder’s Proportionate Share of and any loss, liability, damage, claim, suit, penalty, cost or expense (including fees and expenses of counsel) incurred without gross negligence or bad faith on the part of the Seller Supermajority and arising out of or in connection with the acceptance or administration of their duties hereunder.

(e)The Seller Supermajority shall have reasonable access to information about the Company and the reasonable assistance of the Company’s former officers and employees for purposes of performing his duties and exercising his rights hereunder, except that no Indemnified Person shall be required to provide any information that is subject to a legal privilege or a protective order or the disclosure of which would violate any Legal Requirements. The Seller Supermajority shall treat confidentially and not use or disclose the terms of this Agreement, the Company Disclosure Schedule, the Purchaser Disclosure Schedule or any non-public information from or about Therachon, Purchaser, the Company or any Indemnified Person and their respective Affiliates to anyone, except that the Seller Supermajority may disclose the terms or information to the other Shareholders or their own employees, attorneys, accountants, financial advisors, agents or authorized representatives on a need-to-know basis, as long as the Person agrees to treat such information confidentially.

(f)The Sellers each waive the provisions of Articles 2146, the third sentence of Article 2179 and Article 2184 of the Civil Code of Quebec with respect to the activities of the mandataries pursuant to this Section 8.8.

Section 9.2Interpretation. When a reference is made in this Agreement to Sections or Schedules, such references shall be to a Section of or Schedule to this Agreement unless otherwise indicated. The words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.” The phrase “made available,” “delivered” or “provided” in this Agreement means that the information referred was (i) provided in writing to Purchaser or its Representatives or (ii) included in the Company’s electronic data room. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. The Exhibits to this Agreement and the Company Disclosure Schedule are hereby incorporated and made a part hereof and are an integral part of this Agreement, and the Company Disclosure Schedule is subject to the rules of construction and interpretation set forth therein. Any capitalized terms used in any schedule or exhibit but not otherwise defined therein shall be defined as set forth in this Agreement. Any reference in this Agreement to “$” or “dollars” means United States dollars, unless expressly stated otherwise.

Section 9.3Counterparts. This Agreement may be executed in two or more counterparts (including by PDF or other electronic transmission), all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto, it being understood that all parties hereto need not sign the same counterpart.

Section 9.4Entire Agreement; Nonassignability; Parties in Interest. This Agreement, the Confidentiality Agreement and the documents and instruments and other agreements specifically referred to herein or therein or delivered pursuant hereto, including the Exhibits and Schedules hereto, including the Company Disclosure Schedule: (i) constitute the entire agreement among the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof, (ii) shall not create or be deemed to create any third party beneficiary rights in any Person not a party to this Agreement or such other agreement, (iii) except by operation of the Agreement, shall not be assigned by operation of law or otherwise except as otherwise specifically provided; provided, however, that each of the Shareholders and Purchaser may (a) assign any or all of its rights and interests hereunder to one or more of its Affiliates, and (b) designate one or more of its Affiliates to perform its obligations hereunder (in any or all of which cases Purchaser or the assigning Shareholder, as the case may be, nonetheless shall remain responsible for the performance of all of its obligations hereunder), and (iv) shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns (which permitted assigns, in the case of Purchaser, shall be its Affiliates only).

Section 9.5Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will

62

achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

Section 9.6Arbitration.

(a)Any disputes or differences between the parties hereto arising out of this Agreement or the transactions contemplated hereby, including any dispute between any Indemnitee and any Indemnifying Party under Article VIII, which the parties are unable to resolve themselves shall be submitted to and resolved by arbitration pursuant to the rules of arbitration set forth in the Civil Code of Québec and the Code of Civil Procedure (Québec), subject to the terms as herein provided. Such arbitration shall be conducted before one arbitrator. If the Parties are unable to agree on a single arbitrator within ten (10) Business Days after expiration of the ten (10) Business Day period following the Claim Notice referred to in Section 8.4(a) the Indemnifying Party and the Indemnitee shall each designate one independent third party who would be qualified to act as an arbitrator hereunder (a “Party Selection Nominee”). Within ten (10) Business Days after the appointment of the Party Selection Nominees, the two Party Selection Nominees shall designate an arbitrator mutually acceptable to them, who is neither of the Party Selection Nominees and is not affiliated with any party in interest to such arbitration and who has substantial professional experience with regard to corporate legal matters. If the Party Selection Nominee chosen by the Indemnifying Party and Party Selection Nominee chosen by the Indemnitee fail to agree upon the arbitrator within such ten (10) Business Day period, the arbitrator shall be appointed by a Judge of the courts of Québec sitting in the Judicial District of Montréal as soon as practicable who is not affiliated with any party in interest to such arbitration and who has substantial professional experience with regard to corporate legal matters.

(b)The arbitrator shall consider the dispute at issue at Montréal, Québec, at a mutually agreed upon time within thirty (30) days (or such longer period as may be acceptable to the Indemnifying Party and the Indemnitee) of the designation of the arbitrator. Notwithstanding the foregoing, the relevant Indemnifying Party and the Indemnitee agree that they will attempt, and they intend that they and the arbitrator should use their best efforts in that attempt, to conclude the arbitration proceeding and have a final decision from the arbitrator within ninety (90) days from the date of selection of the arbitrator; provided, however, that the arbitrator shall be entitled to extend such 90-day period one or more times to the extent necessary for such arbitrator to place a dollar value on any claim that may be unliquidated. The arbitrators shall immediately deliver a decision with respect to the dispute to each of the parties, who shall promptly act in accordance therewith. Each Indemnifying Party and the Indemnitee Party to such arbitration agrees that any decision of the arbitrator shall be final, conclusive and binding and no appeal shall lie therefrom. It is specifically understood and agreed that any party may enforce any award rendered pursuant to the arbitration provisions of this Section 9.6 by bringing suit in any court of competent jurisdiction.

(c)All fees, costs and expenses (including attorneys’ fees and expenses) incurred by the party that prevails in any such arbitration commenced pursuant to this Section 9.6 or any judicial action or proceeding seeking to enforce the agreement to arbitrate disputes as set forth in this Section 9.6 or seeking to enforce any order or award of any arbitration commenced pursuant to this Section 9.6 may be assessed against the party or parties that do not prevail in such arbitration in such manner as the arbitrator or the court in such judicial action, as the case may be,

63

may determine to be appropriate under the circumstances. All costs and expenses attributable to the arbitrator shall be allocated among the parties to the arbitration in such manner as the arbitrator shall determine to be appropriate under the circumstances.

Section 9.7Governing Law; Venue. EXCEPT AS SET FORTH IN Section 2.4 WITH RESPECT TO RESOLUTION OF CERTAIN DISPUTES RELATING TO ANY POST- CLOSING ADJUSTMENT, THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF QUÉBEC AND OF CANADA APPLICABLE THEREIN, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF. EACH OF THE PARTIES HERETO IRREVOCABLY CONSENTS TO THE EXCLUSIVE JURISDICTION AND VENUE OF ARBITRATION PROVIDED AT Section 9.6 WITH THE EXCEPTION OF PROVISIONAL MEASURES, SUCH AS INJUNCTIVE RELIEF, SAFEGUARD ORDERS OR SEIZURE BEFORE JUDGMENT, WHICH WILL BE THE EXCLUSIVE JURISDICTION OF THE COURTS OF QUÉBEC IN THE JUDICIAL DISTRICT OF MONTRÉAL. EACH OF THE PARTIES, AGREES THAT PROCESS MAY BE SERVED UPON THEM IN ANY MANNER AUTHORIZED BY THE LAWS OF QUÉBEC FOR SUCH PERSONS, AND WAIVES AND COVENANTS NOT TO ASSERT OR PLEAD ANY OBJECTION THAT THEY MIGHT OTHERWISE HAVE TO SUCH JURISDICTION AND SUCH PROCESS.

Section 9.8Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

Section 9.9Specific Performance. The parties hereto agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties hereto shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity and without proof of actual damages or the requirement to post bond; provided that, notwithstanding the foregoing, from and after the Closing, Article VIII shall govern with respect to Indemnity Claims.
