ARTICLE 2

Purchase and Sale

2.1 Purchase and Sale of Acquired Assets.

(a) Acquired Assets. Upon the terms and subject to the conditions of this Agreement, at the Closing, OTI will sell, convey, assign, deliver and set over to MSB, and MSB will purchase and accept, all of the right, title, benefit and interest of OTI in, to and under the Acquired Assets, free and clear of all Liens. At the Closing, the sale, conveyance, assignment and delivery of OTI’s right, title, benefit and interest in, to and under the Acquired Assets will be effected pursuant to the General Assignment and Intellectual Property Assignment.

(b) Excluded Assets. Notwithstanding anything to the contrary contained herein, the Acquired Assets do not include, and in no event will MSB acquire any right, title, benefit or interest in, to or under, any of the Excluded Assets.

(c) Assumed Liabilities. Upon the terms and subject to the conditions of this Agreement, at the Closing, MSB will assume and agree to pay, perform and discharge or hold OTI harmless from the Assumed Liabilities. The assumption of the Assumed Liabilities by MSB will be effected pursuant to the Assumption Agreement.

(d) Excluded Liabilities. Notwithstanding anything to the contrary contained herein, the Assumed Liabilities will not include, and in no event will MSB assume, be required to pay, perform, discharge or hold OTI or any OTI Indemnified Parties harmless from the Excluded Liabilities.

(e) Reimbursement for Certain Payments.

(i) All ad valorem Taxes on personal property or any similar Taxes with respect to the Acquired Assets, other than Transfer Taxes (“Property Taxes”) shall be prorated between MSB and OTI as of the Closing Date, computed by multiplying the amount of Property Taxes for the Tax period for which the same are levied by a fraction, the numerator of which is the number of days in such Tax period up to and including the Closing Date and the denominator of which is the number of days in such Tax period. In connection with such proration of Property Taxes, in the event that actual Property Tax figures are not available at the Closing Date, proration of Property Taxes shall be based upon the actual Property Taxes for the preceding fiscal year for which actual Property Tax figures are available, and re-prorated when actual Property Tax figures become available. For the avoidance of doubt, Property Taxes allocated to OTI pursuant to this Section 2.1(e)(i) shall constitute Excluded Liabilities. To the extent one Party makes a payment of Property Taxes allocated to the other Party, such other Party shall promptly reimburse the paying Party upon receipt of written notice that such Property Taxes have been paid.

(ii) If OTI makes payment under any of the Assumed Liabilities (which OTI will have no obligation whatsoever to do), then MSB will reimburse the amount of such payment to OTI that made the payment within five (5) Business Days of receipt by MSB of a demand for reimbursement, together with corresponding documentation of such payment. If MSB makes payment under any of the Excluded Liabilities (which MSB will have no obligation whatsoever to do), then OTI will reimburse the amount of such payment to MSB within five (5) Business Days of receipt by OTI of a demand for reimbursement, together with corresponding documentation of such payment.

2.2 Development and Commercialization of Products. Notwithstanding anything herein to the contrary, as between the Parties from and after the Closing, MSB shall have the sole right to control and conduct the development, manufacture and commercialization of the Products as it deems appropriate in its sole discretion and there are no express or implied obligations with respect thereto.

ARTICLE 3

Consideration

3.1 Purchase Price. MSB shall pay the amounts set forth in Exhibit 3.1 and Exhibit 3.2, in accordance with this Section 3.1 and Section 3.2 below.

(a) Closing Consideration. MSB shall pay to OTI the amounts set forth in paragraph (a) of Exhibit 3.1 as set forth therein.

(b) Contingent Consideration. MSB shall pay to OTI the amounts set forth in paragraph (b) of Exhibit 3.1 as set forth therein.

(i) The Contingent Consideration shall be due and payable ten (10) Business Days following the satisfaction of the conditions precedent to any payment of Contingent Consideration pursuant to Section 3.1(b) to the account designated in writing by OTI reasonably in advance. If the Contingent Consideration is to be paid, in whole or in part, through the issuance of MSB Ordinary Shares, the MSB Ordinary Shares shall be issued to OTI no later than ten (10) Business Days following the satisfaction of the respective conditions precedent to any payment of Contingent Consideration pursuant to Section 3.1(b) (“Contingent Shares Payment Date”).

(ii) The Contingent Consideration, will be payable in cash or, if Mesoblast Limited is admitted to the official list of the ASX at the time the Contingent Consideration is payable, through the issuance to OTI of MSB Ordinary Shares, or a mix thereof, in each case at the sole discretion of MSB, unless and only to the extent that on the date the MSB Ordinary Shares are to be issued under Section 3.1(c)(i) (A) all or a portion of the MSB Ordinary Shares are prohibited from issuance under Listing Rule 7.1 or (B) the issuance of MSB Ordinary Shares to OTI would cause OTI to breach Section 606 of the Corporations Act, in which case such amount of the Contingent Consideration that cannot be paid through the issuance of MSB

Ordinary Shares shall be payable to OTI in cash. The MSB Ordinary Shares shall be valued on a per share basis equal to the five (5) consecutive trading day volume weighted average price as calculated by Bloomberg Financial L.P. under the function “VWAP” or other similar manner as notified by MSB to OTI in advance and to which OTI has no reasonable objection (“VWAP”), up to (and including) the trading day immediately prior to the Contingent Shares Payment Date, with respect to the applicable payment of Contingent Consideration, which will be converted to U.S. Dollars using the closing “U.S.-dollar foreign exchange rate” reported by The Wall Street Journal under the Market Data Center tab (U.S. Internet edition, at www.wsj.com) for the Business Day immediately prior to the applicable Contingent Shares Payment Date (the “Issue Price”). To the extent that MSB elects to pay any Contingent Consideration in the form of MSB Ordinary Shares, it shall be a condition to the issuance of such MSB Ordinary Shares that OTI deliver (i) a certificate in form and substance reasonably satisfactory to MSB confirming the accuracy of the representations set forth in Sections 5.1(q) through (s), inclusive, hereof and (ii) the Restriction Agreement (with respect to all of the Contingent Consideration payable in the form of the issue of MSB Ordinary Shares other than any MSB Ordinary Shares which are Non-Holding Period Shares) substantially in the form attached hereto as Exhibit F.

(iii) To the extent that MSB makes any payment hereunder (including pursuant to Section 3.1(c)(iv)) in MSB Ordinary Shares, OTI shall not Transfer such MSB Ordinary Shares prior to the date that is twelve (12) months following the issuance of such MSB Ordinary Shares to OTI (the “Holding Period”) and provided that any subsequent Transfer is registered under, exempt from or not subject to the provisions of Section 5 of the Securities Act of 1933, as amended (the “Securities Act”). OTI confirms that as at the date of this Agreement it has no intention of Transferring any MSB Ordinary Shares during any applicable Holding Period. Any attempted Transfer in violation of the foregoing shall be of no effect and null and void, regardless of whether the purported transferee has any actual or constructive knowledge of the Transfer restrictions set forth in this Agreement, and shall not be recorded on the share register of Mesoblast Limited. Notwithstanding the foregoing, to the extent consistent with applicable Law, MSB may in its sole discretion, designate one or more payments of Contingent Consideration in the form of MSB Ordinary Shares as not subject to a Holding Period by written notice to OTI, in which case, the provisions of this Section 3.1(c)(iii) shall not apply to such issuance of MSB Ordinary Shares, provided that such MSB Ordinary Shares are freely tradeable without further action of OTI. MSB Ordinary Shares which are not subject to a Holding Period pursuant to the preceding sentence are sometimes referred to herein as “Non-Holding Period Shares”.

(iv) Notwithstanding the foregoing, with respect to any issuance of MSB Ordinary Shares as Contingent Consideration other than Non-Holding Period Shares (each such issuance, an “Applicable Issuance”), if the VWAP for the MSB Ordinary Shares for the five consecutive trading day period calculated up to the close of trading on the day immediately prior to the date of the expiration of the Holding Period with respect to such Applicable Issuance (for each Applicable Issuance, the “Holding Period Price”) is below the applicable Issue Price, MSB shall pay to OTI an additional amount equal to (x) the difference between the applicable Issue Price and the Holding Period Price multiplied by (y) the number of MSB Ordinary Shares issued in such Applicable Issuance (the “Additional Consideration”). Such amount of Additional Consideration shall be paid (A) fifty percent (50%) in cash unless agreed otherwise by the Parties in writing and (B) the remaining fifty percent (50%), as determined in MSB’s sole

discretion, in either cash or, if Mesoblast Limited is admitted to the official list of the ASX, through the issuance to OTI of additional MSB Ordinary Shares, unless and only to the extent that on the date the MSB Ordinary Shares are to be issued under this Section 3.1(c)(iv) (I) all or a portion of the MSB Ordinary Shares are prohibited from issuance under Listing Rule 7.1 or (II) the issuance of MSB Ordinary Shares to OTI would cause OTI to breach Section 606 of the Corporations Act, in which case such amount of the Additional Consideration that cannot be paid through the issuance of MSB Ordinary Shares shall be paid to OTI in cash. The additional MSB Ordinary Shares shall be valued at the Holding Period Price for such Applicable Issuance or a mix thereof. For the avoidance of doubt, no adjustment pursuant to this Section 3.1(c)(iv) shall be made with respect to MSB Ordinary Shares issued pursuant to this Section 3.1(c)(iv), regardless of the trading price of MSB Ordinary Shares at any time. Cash payments of Additional Consideration shall be made by wire transfer in immediately available funds to an account designated in writing by OTI to MSB at least five (5) Business Days prior to the date when the payment is due and payments of Additional Consideration to be made in MSB Ordinary Shares shall be made no later than ten (10) Business Days following the expiration of the Holding Period with respect to the Applicable Issuance.

(v) In the event that the MSB Ordinary Shares are listed on a recognized securities exchange as a substitute for the ASX, then the Parties shall discuss, in good faith, the terms of this Section 3.1(c) and Section 5.2(e) in connection with such substituted exchange, provided that the Holding Period shall not be extended.

3.2 Earnout.

(a) In addition to the amounts payable under Section 3.1, potential Earnout payments shall be as set forth on Exhibit 3.2.

(b) Offsets. MSB shall have the right to offset from any Earnout or amounts payable under Section 3.1(b) hereunder any customary and reasonable amounts paid (including royalties and other payments) to third Persons for rights owned or controlled by such third Person for the use of any Acquired Assets, provided that MSB provides written notice to OTI regarding the alleged rights of such third Person prior to any such offset. For clarity, any such offset shall be without limitation or prejudice of any breach of warranty by OTI.

(c) Payment. Following the first commercial sale of an Earnout Product and during the Earnout Period, MSB shall provide to OTI a written report for each calendar year showing the Net Sales during such calendar year and the Earnout payable under this Section 3.2 in sufficient detail to allow OTI to verify the amount of Earnout paid by MSB with respect to such calendar year. Such reports shall be due no later than ninety (90) days following the end of each calendar year. The Earnout shown to have accrued by each report provided under this Section 3.2(c) shall be due and payable on the date such report is due. All Earnout payments shall be made in Dollars by electronic wire transfer of immediately available funds to an account designated in writing by OTI to MSB at least five (5) Business Days prior to the date when the payment is due. If any currency conversion is required in connection with the calculation of the Earnout, such conversion shall be made in a manner consistent with MSB’s normal practices used to prepare its audited financial statements for external reporting purposes.

(d) Records and Audits.

(i) MSB will keep complete, true and accurate books and records in sufficient detail for OTI to determine payments due to OTI under this Article 3, including Earnouts. MSB will keep such books and records for at least three (3) years following the end of the calendar year to which they pertain.

(ii) OTI shall have the right during such three (3)-year period to appoint at its expense an independent certified public accountant of nationally recognized standing (the “Accounting Firm”) acceptable to MSB to inspect or audit the relevant records of MSB to verify such amounts were correctly determined. MSB shall make such records available for audit by the Accounting Firm during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from OTI, solely to verify such payments hereunder were correctly determined. Such audit right shall not be exercised by the Auditing Party more than once in any calendar year and may cover a period ending not more than thirty-six (36) months prior to the date of such request. All records made available for audit shall be deemed to be confidential information of MSB. If the amount of paid hereunder was over-reported, OTI shall promptly (but in any event no later than thirty (30) days after the Accounting Firm’s report) make payment to MSB of the over-reported amount, or if the amount paid was under-reported, MSB shall promptly (but in any event no later than thirty (30) days after the Accounting Firm’s report) make payment to OTI of the underreported amount. OTI shall bear the full cost of such audit unless such audit discloses an underreporting of more than the greater of (A) seven percent (7%) of the aggregate amount payable for the term of the audit, and (B) USD $250,000, in which case MSB shall reimburse OTI for all expenses of third Persons incurred in connection with such audit.

(iii) The Accounting Firm will disclose to OTI only whether the payments are correct or incorrect and the specific details concerning any discrepancies. MSB is entitled to require the Accounting Firm to execute a reasonable confidentiality agreement prior to commencing any audit under this Section 3.2. The Accounting Firm shall provide a copy of its report and findings to OTI and MSB simultaneously.

3.3 Taxes. Each Party shall be responsible for its own Tax liabilities arising under this Agreement. Accordingly, OTI shall be liable for all income and other Taxes (including interest) resulting from any payments made by MSB to OTI under this Agreement (“Agreement Payments”). If applicable Law requires the withholding of Taxes, MSB shall make such withholding payments in a timely manner and shall subtract the amount thereof from the payments hereunder, and such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person to whom such amounts would otherwise have been paid. MSB shall promptly (as available) submit to OTI appropriate proof of payment of the withheld Taxes as well as the official receipts within a reasonable period of time. MSB shall provide OTI reasonable assistance in order to allow OTI to obtain the benefit of any applicable present or future treaty against double taxation or refund or reduction in Taxes which may apply to the payments hereunder. Notwithstanding the foregoing, if as a result of a Party assigning this Agreement or changing its domicile additional Taxes become due that would not have otherwise been due hereunder with respect to Agreement Payments, such Party shall be responsible for all such additional Taxes. Notwithstanding anything to the contrary, OTI agrees to pay all Transfer

Taxes with respect to the transactions contemplated by this Agreement. The Parties shall use commercially reasonable efforts to minimize the amount of any Transfer Taxes, including by providing appropriate documentation in connection with any available exemption from or reduction in the amount of such Transfer Taxes.

3.4 Allocation of Consideration. The Parties agree to allocate the amounts paid pursuant to this Article 3 among the Acquired Assets for Tax purposes in accordance with applicable Law and as set forth in Exhibit 3.4. The Parties shall not file any Tax Return or otherwise take any position inconsistent with such allocation unless otherwise required by applicable Law.

This Agreement has been duly executed and delivered by OTI, and (assuming due authorization, execution and delivery by MSB) this Agreement constitutes, and, when so executed and delivered, the Related Agreements and the Restriction Agreement will constitute, a valid and legally binding obligation of OTI, enforceable against it in accordance with its terms, except as enforceability may be affected by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Laws relating to or affecting creditors’ rights generally, and general equitable principles (whether considered in a proceeding in equity or at law).

(i) The execution and delivery of this Agreement does not, the execution of the Related Agreements or the Restriction Agreement will not, and the consummation of the Transactions will not, conflict with or result in any violation of or default under (with or without notice or lapse of time, or both) or give rise to, any payment obligation, or a right of termination, cancellation, modification or acceleration of any obligation or loss of any benefit under (any such event, a “Conflict”) (A) any provision of OTI’s Organizational Documents, (B) any Assigned Contract, or (C) any Law applicable to the Business, the Acquired Assets or the Assumed Liabilities.

Following the Closing, MSB will be permitted to exercise all of its rights under the Assigned Contracts without the payment of any additional amounts or consideration other than ongoing fees, royalties or payments that OTI would otherwise be required to pay pursuant to the terms of such Assigned Contracts had the Transactions not occurred.

(d) Governmental Approvals and Filings.

(iv) OTI possesses all Regulatory Authorizations necessary to its conduct of the Business as currently conducted. The Regulatory Authorizations set forth in Section 5.1(g)(iv) of the Disclosure Schedules constitute all of the Regulatory Authorizations used in, or held for use in, the Business by OTI, as of the date hereof. Each such Regulatory Authorization is validly and presently in effect (and except as disclosed in Section 5.1(g)(iv) of the Disclosure Schedules, the continuing validity and effectiveness of such Regulatory Authorization will not be affected by the consummation of the Transactions), and OTI is not in default under any such Regulatory Authorization in any material respect. There are no Actions pending, nor to the Knowledge of OTI, threatened, that seek the revocation, cancellation, suspension, failure to renew or adverse modification of any such Regulatory Authorizations.

(h) Assigned Contracts.

OTI has made available to MSB true and complete copies of each such Contract, together with all amendments, waivers and supplements thereto.

(iv) Except as set forth on Section 5.1(h)(iv) of the Disclosure Schedule, no amounts are or will be due to any third Person under any Assigned Contract as a result of the conduct of the Business after the Closing.

(i) Legal Proceedings; Orders. Except as set forth on Section 5.1(i) of the Disclosure Schedules, there are no Actions pending against or, to the Knowledge of OTI, threatened against, the Business or any Acquired Assets. There is no claim pending or, to the Knowledge of OTI, threatened, against any Person who has a contractual right or a right pursuant to applicable Law to indemnification from OTI related to facts and circumstances involving the Business or the Acquired Assets. There are no Actions pending against, or to the Knowledge of OTI, threatened against, the Business, the Products or any of the Acquired Assets that would reasonably be expected to prevent or delay the ability of OTI to enter into and perform its obligations under this Agreement or consummate the Transactions.

Upon the consummation of the Transactions, MSB will acquire good, valid title to, or a valid leasehold or license interest in, the Acquired Assets, free and clear of all Liens, except for Permitted Liens. Without limiting the foregoing, neither Genzyme Corporation nor any of its Affiliates has any right, title or interest (including any Lien) with respect to any of the Acquired Assets.

(ii) The Scheduled Assets constitute all of the assets, properties and rights that are necessary and sufficient to conduct the Business in substantially the manner as conducted by OTI.

(iii) The material items of Tangible Personal Property have been maintained in accordance with OTI’s normal practice and are in good repair and usable condition for the conduct of the Business as currently conducted, ordinary wear and tear and aging excepted.

(k) Compliance with Law.

(i) OTI has not been in violation of, or is not the subject of any Action with respect to the violation of, any Law or Order, and has not received any FDA Form 483, “warning letters,” or “untitled letters,” or other similar notice of inspectional observations or deficiencies from any Governmental or Regulatory Authority in connection with the Business. No Action is pending, or to the Knowledge of OTI, threatened, with respect to any violation of any Law or Order by OTI, and OTI is and has been in compliance in all material respects with all Laws and Orders, in each case relating to the conduct of the Business (including, privacy and export laws), or pertaining to the Acquired Assets or Assumed Liabilities.

confidentiality. The Parties will each provide the other with such assistance as may reasonably be requested in connection with the preparation of any Tax Return relating to the Business or Acquired Assets, or the audit or other examination by any Tax authority or judicial or administrative proceeding relating to or liability for Taxes arising out of the conduct of the Business or ownership of the Acquired Assets.

If, at any time and from time to time after the Closing, MSB identifies to OTI in writing any specific asset, property or right that it reasonably determines (i) is within the definition of Acquired Assets but has not been delivered to MSB pursuant to Section 6.1 or otherwise and (ii) in MSB’s reasonable judgment, is, or is likely to be, material to the continued conduct of the Business, including the development, manufacture or commercialization of any Product, then OTI shall use commercially reasonable efforts to promptly deliver such asset to MSB (or, if undeliverable, provide MSB with the benefit thereof). Similarly, if, at any time and from time to time after the Closing, OTI identifies to MSB any specific asset, property or right in writing that it reasonably determines that (A) is not within the definition of Acquired Assets but has been inadvertently delivered to MSB pursuant to Section 4.2 or otherwise and (B) in OTI’s reasonable judgment, is, or is likely to be, material to the continued conduct of the Excluded Business conducted by OTI as of the date hereof, then MSB shall use commercially reasonable efforts to promptly reconvey such asset, property or right to OTI (or, if the reconveyance is impractical, provide OTI with the benefit thereof).

If a Person entitled to indemnification under this Article 7 (the “Indemnified Party”) intends to make a claim for Damages (any, a “Claim”) against the Party obligated to provide such indemnification (the “Indemnifying Party”), then the Indemnified Party will give written notice (a “Claim Notice”) to the Indemnifying Party promptly after the Indemnified Party becomes aware and appreciates that any fact, condition or event is likely to give rise to Damages for which indemnification may be sought under this Article 7. Each Claim Notice must describe in reasonable detail the nature and amount of the Claim, the basis of the Indemnified Party’s request for indemnification under this Agreement and all material

information in the Indemnified Party’s possession relating to such Claim, including any fact, condition or event giving rise to the Damages giving rise to the Claim. The failure to give such prompt written notice shall not relieve the Indemnifying Party of its indemnification obligations hereunder, except to the extent the Indemnifying Party is materially prejudiced thereby. Notwithstanding the foregoing, a Claim Notice that relates to a representation or warranty that is subject to the survival period set forth in Section 7.3 must be made within such survival period, whether or not the Indemnifying Party is prejudiced by any failure to give a Claim Notice relating thereto. Notwithstanding anything to the contrary contained herein, with respect to any Claim that is not a Third-Party Claim, “Damages” shall exclude all indirect, consequential and punitive damages and the Indemnified Party shall have no right to recover any such damages.

(b) Third-Party Claim.

(i) Without limiting the Indemnified Party’s obligations under Section 7.2(a), if the Claim for which indemnification is being sought arises from any Action brought by a third Person (a “Third-Party Claim”) against the Indemnified Party, then the Claim Notice therefor shall include copies of all material written evidence thereof and all filings that have been made by such third Person in connection therewith and served on the Indemnified Party, and shall indicate the estimated amount, if reasonably practicable, of the Damages that have been or may be incurred by the Indemnified Party.

(ii) Subject to the conditions of this Section 7.2(b)(ii), the Indemnifying Party shall have the right to control the conduct of the defense of any Third Party Claim, at the Indemnifying Party’s expense and using counsel selected by the Indemnifying Party to which the Indemnified Party has no reasonable objection. Notwithstanding the foregoing, the Indemnifying Party shall not be permitted to control the conduct of the defense of any Third Party Claim unless (A) within 30 days (or such longer period of time as the Indemnified Party and the Indemnifying Party may mutually agree in writing) after the Indemnified Party’s delivery of a written notice of a Third-Party Claim pursuant to Section 7.2(b)(i), the Indemnifying Party gives written notice to the Indemnified Party that it intends to assume and conduct the defense and settlement of such Third-Party Claim; (B) the Indemnifying Party acknowledges in writing to the Indemnified Party (to the extent capable of being acknowledged based on the information provided) that there exists an indemnification obligation by the Indemnifying Party relating to such Third-Party Claim; (C) the amount reasonably claimed in such Third-Party Claim, together with any amounts that are reasonably necessary to satisfy any unsatisfied Claim made by the Indemnified Party is less than or equal to the then applicable limitations of liability for indemnification with respect to such Third-Party Claim as provided herein; (D) such Third-Party Claim does not involve criminal or regulatory enforcement action or seek an injunction or other equitable relief against the Indemnified Party or any of its affiliates; (E) no legal conflict exists between the Indemnified Party and the Indemnifying Party in connection with the defense of such Third-Party Claim; (F) the conduct of the defense of, settlement of or an adverse resolution with respect to such Third-Party Claim would not reasonably be expected to be adverse in any material respect to the Indemnified Party’s or any of its affiliates’ reputation, business or operations; and (G) the Indemnified Party actively and diligently conducts the defense of such Third Party Claim. The Indemnifying Party will lose any previously acquired right to control the defense of any Third-Party Claim if for any reason any of the foregoing conditions set forth in clause (B) through clause (G) of the preceding

sentence are no longer satisfied, and the Indemnified Party will have the right to take over the control of such defense.

(iii) If the Indemnifying Party is exercising a right to control the conduct of the defense of a Third-Party Claim, the Indemnified Party shall have the right to participate in the defense of such Third-Party Claim at its own expense and with its own counsel and the Indemnifying Party shall keep the Indemnified Party reasonably informed as to the progress of such Third-Party Claim. The Indemnifying Party may not consent to the entry of any judgment or enter into any compromise or settlement with respect to any Third Party Claim without the prior written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed) unless the Indemnifying Party is exercising a right to control the conduct of the defense of a Third-Party Claim and the terms, conditions and existence of such judgment, compromise or settlement are confidential and such judgment, compromise or settlement (A) provides for the payment by the Indemnifying Party of money as sole relief for the claimant; (B) results in a dismissal with prejudice of such Third-Party Claim, including a full and general release of the Indemnified Party and its Affiliates from all liabilities arising or relating to, or in connection with, the Third-Party Claim; and (C) includes an affirmative statement that there is no finding or admission of any violation of any law or the rights of any person or entity, and has no adverse effect on any other claims that may be made against the Indemnified Party. The Indemnified Parties will have no liability with respect to any compromise or settlement of, or the entry of any judgment arising from, any Third-Party Claim effected without the Indemnified Party’s consent.

(iv) If the Indemnifying Party elects not to control or is not entitled to control the conduct of the defense of a Third-Party Claim, then the Indemnified Party shall have the right to control the conduct of the defense of the Third Party Claim, at the Indemnifying Party’s expense and using counsel selected by the Indemnified Party to which the Indemnifying Party has no reasonable objection. In such event, the Indemnifying Party shall have the right to participate in the defense of such Third-Party Claim at its own expense and with its own counsel, and the Indemnified Party shall keep the Indemnifying Party reasonably informed as to the progress of such Third-Party Claim. If the Indemnified Party is exercising a right to control the conduct of the defense of a Third-Party Claim, then except with the written consent of the Indemnifying Party (which shall not be unreasonably withheld, conditioned or delayed), the Indemnified Party may not consent to the entry of any judgment or enter into any compromise or settlement with respect to any Third Party Claim without the prior written consent of the Indemnifying Party (not to be unreasonably withheld, conditioned or delayed).

7.3 Survival. The representations and warranties contained in Sections 5.1(a) (“Organization and Existence”), 5.1(b) (“Authority and Approval”), 5.1(j)(i) (Title), 5.1(m) (“No Brokers”), 5.2(a) (“Organization and Existence”), 5.2(b) (“Authority and Approval”), and 5.2(g) (“No Brokers”) (with respect to each Party, the “Fundamental Representations”) will survive the Closing until sixty (60) calendar days after the expiration of the applicable statute of limitations and the representations and warranties set forth in Sections 5.1(l) (“Intellectual Property”) and 5.1(o)(iv) will survive until thirty-six (36) months following the Closing Date. All other representations and warranties contained in this Agreement will survive the Closing for a period ending upon the earlier of (a) the completion of MSB’s audit of the first fiscal year that ends following the Closing or (b) the date that is eighteen (18) months following the Closing Date (the

“Survival Date”), at which time they shall terminate, be void and of no further force or effect. No indemnification will be payable for any Claim for Damages pursuant to Section 7.1(a)(i) or Section 7.1(b)(i) with respect to any inaccuracy or breach of any representation or warranty after termination of the applicable survival period specified in this Section 7.3, except with respect to Claims made prior to such termination pursuant to Section 7.2 but not then resolved (such representation or warranty surviving with respect to such Claim until resolution of such Claim).

7.4 Limitations. The rights to indemnification under Sections 7.1(a) and 7.1(b) are subject to the following limitations:

(a) Cap. The aggregate amount which all MSB Indemnified Parties will be entitled to receive for all claims under Section 7.1(a) is limited to ten percent (10%) of the value of all consideration (whether cash or MSB Ordinary Shares) actually paid by MSB to OTI pursuant to Sections 3.1 and 3.2 (the “Cap”). For such purposes, the value of any MSB Ordinary Shares shall be deemed the amount against which such MSB Ordinary Shares were issued pursuant to Section 3.1 or 3.2, as applicable.

(b) Deductible. OTI will have no obligation to indemnify any MSB Indemnified Parties for any Claims under Section 7.1(a) until the aggregate amount of all Damages incurred by MSB Indemnified Parties for which a Claim is brought under Section 7.1(a), exceeds $250,000 (the “Deductible Amount”), and thereafter OTI shall only be liable for Damages in excess of the Deductible Amount, subject to the Cap.

(c) Exclusions from Sections 7.4(a) and 7.4(b) Limitations. The limitations under Sections 7.4(a) and 7.4(b) will not apply with respect to (i) any Claims for indemnification under Section 7.1(a)(i) with respect to any misrepresentation or breach by OTI of any Fundamental Representations, or (ii) any Claims for indemnification under Section 7.1(b)(i) with respect to any misrepresentation or breach by MSB of any Fundamental Representation; provided, however, that (1) the aggregate amount which all MSB Indemnified Parties will be entitled to receive with respect to any misrepresentation or breach of a Fundamental Representation, when taken together with all other Claims under Section 7.1(a)(i) and (ii), shall be limited to the amount actually received by OTI pursuant to Sections 3.1 and 3.2; (2) the aggregate amount which all MSB Indemnified Parties will be entitled to receive with respect to any Claims for indemnification under Section 7.1(a)(iii), shall not be capped; (3) the aggregate amount which all OTI Indemnified Parties will be entitled to receive with respect to any misrepresentation or breach of a Fundamental Representation, when taken together with all other Claims under Section 7.1(b)(i) and (ii), shall be limited to the amount actually received by OTI pursuant to Sections 3.1 and 3.2; (4) the aggregate amount which all of OTI Indemnified Parties will be entitled to receive with respect to any Claims for indemnification under Sections 7.1(b)(iii), shall not be capped; and (5) MSB shall have the right to offset any Claims that would have been indemnifiable by OTI hereunder but for the Cap (any “Excess Damages”) against ten (10%) of the amounts payable to OTI under Sections 3.1 and 3.2 until such time as such Excess Damages have been fully offset.

(d) Other Limitations. Notwithstanding anything to the contrary contained in this Agreement or otherwise, the Parties expressly intend and agree as follows:

(i) The amount of any Damages incurred by an Indemnified Party shall be reduced by any amount actually recovered by such Indemnified Party with respect thereto under any insurance coverage (net any costs and expenses, including the present value of any insurance premium increases); provided, however, that no Indemnified Party shall be obligated to seek any such proceeds, benefits or recoveries.

(ii) The indemnification provisions provided for in this Article 7 will be the exclusive remedy for any breach of any representation, warranty, covenant, or agreement contained in this Agreement; provided, however, that nothing in this Agreement shall limit the rights or remedies of any Indemnified Party in connection with (A) any fraud in connection with this Agreement, the Related Agreements or the Restriction Agreement (including the negotiation or execution hereof or thereof), (B) any Related Agreement or the Restriction Agreement or (C) seeking any equitable remedies.

(iii) Each Indemnified Party shall use commercially reasonable efforts to mitigate any Damages which are the subject of Claims hereunder.

7.5 Resolution of Indemnification Disputes. If an Indemnifying Party disputes or contests the basis or amount of any Claim set forth in a Claim Notice delivered by an Indemnified Party in accordance with the provisions of Article 7, the dispute will be resolved as set forth in this Section 7.5 below.

(a) An Indemnifying Party may object to a claim for indemnification set forth in a Claim Notice by delivering to the Indemnified Party seeking indemnification a written statement of objection to the claim made in the Claim Notice (an “Objection Notice”); provided, however, that, to be effective, such Objection Notice must (A) be delivered to the Indemnified Party prior to the 60th day following the receipt of the applicable Claim Notice (such deadline, the “Objection Deadline” for such Claim Notice and the Claims for indemnification contained therein) and (B) set forth in reasonable detail the nature of the objections to the Claims in respect of which the objection is made.

(b) If the Indemnifying Party does not object in writing (as provided in Section 7.5(a)) to the Claims contained in such Claim Notice prior to the Objection Deadline for such Claim Notice, the Indemnifying Party shall be deemed to have delivered an Objection Notice on the Objection Deadline.

(c) In case an Indemnifying Party timely delivers, or is deemed to have delivered, an Objection Notice in accordance with Section 7.5(a), the Indemnifying Party and the Indemnified Parties shall attempt in good faith to agree upon the rights of the respective Parties with respect to each of such Claims. If the Indemnifying Party and the Indemnified Parties reach an agreement, a memorandum setting forth such agreement shall be prepared and signed by all applicable Parties (any claims covered by such an agreement, “Settled Claims”). Any amounts required to be paid as a result of a Settled Claim shall be paid by the Indemnifying Party to the Indemnified Parties pursuant to the Settled Claim within 30 days of the applicable claim becoming a Settled Claim, subject to Section 7.4.

(d) If no such agreement can be reached after good faith negotiation prior to 45 days after delivery of an Objection Notice, then upon the expiration of such 45-day period either the Indemnifying Party or the Indemnified Parties may demand arbitration of the matter unless the amount of the Damages that is at issue is the subject of a pending litigation with a third Person, in which event arbitration shall not be commenced until such amount is ascertained or both Parties agree to arbitration, and in either such event the matter shall be settled by arbitration conducted pursuant to Section 9.2.

(e) The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to the validity and amount of any claim in such Claim Notice shall be final, binding, and conclusive upon the Parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s). Within 30 days of a decision of the arbitrator(s) requiring payment by an Indemnifying Party to an Indemnified Party, such Indemnifying Party shall make the payment to such Indemnified Party, subject to Section 7.4.

7.6 Tax Treatment. The Parties agree to treat all indemnification payments made pursuant to this Article 7 as adjustments to the purchase price for all Tax purposes.

ARTICLE 8

Non-Competition

8.1 General. OTI acknowledges that an important part of the benefit that MSB will receive in connection with the Transactions is the ability to conduct the Business free from competition from OTI, either directly or indirectly through a legal entity which OTI controls, is controlled by or is under common control with. In order that MSB may enjoy such benefits, for a period of eight (8) years from the Closing Date (the “Exclusivity Period”), OTI shall not, directly or indirectly through a legal entity which OTI controls, is controlled by or is under common control with, develop, manufacture or commercialize (including seeking Marketing Authorizations for), or authorize, license or otherwise assist any third Person in developing, manufacturing or commercializing (including providing access or right of reference to filings of OTI with any Governmental or Regulatory Authority), or supply to any third Person, any product containing or derived from any ceMSC or any other culture expanded stem cell that can progress to more than one (1) mesenchymal lineage. Additionally, OTI hereby waives any and all of its rights to enforce the terms of any non-competition or similar agreement with any former employee of OTI solely with respect to any such former employee’s employment with MSB beginning after the Closing Date.

8.2 Enforceability. If any Governmental or Regulatory Authority determines that the foregoing restrictions are too broad or otherwise unreasonable under applicable Law in a particular country, the Governmental or Regulatory Authority is hereby requested and authorized by the Parties to revise the foregoing restrictions to include the maximum restrictions allowable under applicable Law in such country. Each of the Parties acknowledges, however, that this Article 8 has been negotiated by the Parties and that the restrictions set forth in Section 8.1 including the Exclusivity Period is reasonable in light of the circumstances pertaining to the Parties.

8.3 Equitable Relief. Notwithstanding any other provision of this Agreement, it is understood and agreed that the remedy of indemnification pursuant to Article 7 and other remedies at law would be inadequate in the case of any breach of the covenants contained in this Article 8, and, accordingly, MSB shall be entitled to equitable relief, including the remedy of specific performance, with respect to any breach or attempted breach of such covenants.

ARTICLE 9

Miscellaneous

9.1 Governing Law and Jurisdiction. This Agreement will be governed by and be construed in accordance with the Laws of the State of New York, without regard however to the conflicts of laws principles thereof.

9.2 Resolution of Conflicts; Arbitration. Except as set forth in Section 7.5, any claim or dispute arising out of or related to this Agreement, or the interpretation, making, performance, breach or termination thereof, shall (except as specifically set forth in this Agreement) be finally settled by binding arbitration in New York, New York in accordance with the then current Commercial Arbitration Rules of the American Arbitration Association and judgment upon the award rendered may be entered in any court having jurisdiction thereof. The arbitrator(s) shall have the authority to grant any equitable and legal remedies that would be available in any judicial proceeding instituted to resolve a dispute.

(a) Selection of Arbitrators. Such arbitration shall be conducted by a single arbitrator chosen by mutual agreement of MSB and OTI. Alternatively, at the request of either Party before the commencement of arbitration, the arbitration shall be conducted by three independent arbitrators, none of whom shall have any competitive interests with MSB or OTI. MSB and OTI shall each select one arbitrator. The two arbitrators so selected shall select a third arbitrator.

(b) Discovery. The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the Parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing Parties about the subject matter of the dispute. The arbitrator, or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions for discovery abuses, including attorneys’ fees and costs, to the same extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification.

(c) Decision. The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to any claim or dispute (including the validity and amount of any indemnification claim set forth in a Claim Notice) shall be final, binding, and conclusive upon the Parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s).

(d) Other Relief. The Parties may apply to a court of competent jurisdiction for a temporary restraining order, preliminary injunction or other interim or conservatory relief, as necessary, without breach of this arbitration provision and without abridgement of the powers of the arbitrator(s).

(e) Costs and Expenses. The Parties agree that each Party shall pay its own costs and expenses (including counsel fees) of any such arbitration, and each Party waives its right to seek an order compelling the other Party to pay its portion of its costs and expenses (including counsel fees) for any arbitration.

9.3 Notices. All notices and other communications hereunder will be in writing and will be deemed to have been duly given when delivered in person, by facsimile, receipt confirmed, or on the next Business Day when sent by overnight courier or on the third Business Day after being sent when sent by registered or certified mail (postage prepaid, return receipt requested) to the respective Party at the following addresses (or at such other address for a Party as will be specified by like notice):

9.4 Amendments.

(a) This Agreement may be amended, superseded, canceled, renewed, or extended, and the terms hereof may be waived, only by a written instrument signed by the Parties hereto or, in the case of a waiver, by the Party against whom the waiver is to be effective. Neither the failure nor any delay by any Party in exercising any right, power or privilege under this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable Law (i) no claim or right arising out of this Agreement can be discharged by one Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party, (ii) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given, and (iii) no notice to or demand on one Party will be deemed to be a waiver of any obligation of such Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement.

(b) A failure or omission of any Party to insist, in any instance, upon strict performance by another Party of any term or provision of this Agreement or to exercise any of its rights hereunder will not be deemed a modification of any term or provision hereof or a waiver or relinquishment of the future performance of any such term or provision by such Party, nor will such failure or omission constitute a waiver of the right of such Party to insist upon future

performance by another Party of any such term or provision or any other term or provision of this Agreement.

9.5 Entire Agreement. This Agreement, together with the Disclosure Schedules, all Exhibits and Schedules hereto and the documents, agreements, certificates and instruments referred to herein and therein, constitutes the entire agreement between the Parties and with respect to the subject matter hereof and supersedes all prior representations, warranties, agreements, and understandings, oral or written, with respect to such matters (including the LOI and the Confidentiality Agreement dated as of 8 January 2013 between Mesoblast Limited and OTI) and other than any written agreement of the Parties that expressly provides that it is not superseded by this Agreement. The Parties acknowledge that OTI and Mesoblast Limited have entered into and delivered that certain Guarantee simultaneously herewith pursuant to which Mesoblast Limited agrees to guarantee the performance of MSB hereunder, all on the terms and conditions set forth therein (the “Guarantee”).

9.6 No Assignment; Binding Effect. This Agreement is not assignable by any Party without the prior written consent of the other Party. Notwithstanding the foregoing, MSB shall be permitted, without the consent of OTI, to assign this Agreement (a) to its Affiliates or to perform this Agreement, in whole or in part, through its Affiliates, provided that MSB shall be primarily liable and responsible for performance by any such Affiliate hereunder, or (b) to any successor or third Person that acquires all or substantially all of the assets to which this Agreement relates by sale, transfer, merger, reorganization, operation of law or otherwise; provided that the assignee agrees in writing to be bound to the terms and conditions of this Agreement. In the event of an assignment permitted under this Section 9.6, the assigning Party shall notify the other Party in writing of such assignment. This Agreement shall be binding upon and shall inure to the benefit of the Parties and their successors and permitted assigns. Any assignment not in accordance with this Section 9.6 shall be null and void.

9.7 Invalidity. In the event that any provision of this Agreement is declared to be void or unenforceable, the remainder of this Agreement will not be affected thereby and will remain in full force and effect to the extent feasible in the absence of the void and unenforceable declaration. The Parties furthermore agree to execute and deliver such amendatory contractual provisions to accomplish lawfully as nearly as possible the goals and purposes of the provision so held to be void or unenforceable.

9.8 Counterparts. This Agreement may be executed in multiple counterparts, each in hardcopy and each of which will be deemed an original but all of which together will constitute one and the same instrument.

9.9 Incorporation by Reference. The Disclosure Schedules and other Schedules and Exhibits and the documents referenced therein constitute integral parts of this Agreement and are hereby incorporated by reference herein.

9.10 Time of the Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

9.11 Specific Performance. The Parties agree that irreparable damages would occur in the event any provision of this Agreement is not performed in accordance with the terms hereof and each of the Parties will be entitled to specific performance of the terms hereof or injunctive relief, in addition to any other remedy at law or in equity that may be available under applicable Law.

9.12 No Third Party Beneficiaries. Except for Article 7 as provided therein, the terms and provisions of this Agreement are intended solely for the benefit of the Parties hereto and their respective successors and permitted assigns, and it is not the intention of the Parties hereto to confer third Person beneficiary rights upon any other Person.

9.13 Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated hereby are consummated, each Party hereto will pay its own costs and expenses incurred in connection with the negotiation, execution and closing of this Agreement, the Related Agreements, the Restriction Agreement, other agreements and documents contemplated hereby and the Transactions.
