The Company, the Owners, Buyer and the Representative may be referred to individually as a “Party” and collectively as the “Parties.” Capitalized terms used but not defined herein shall have the meanings given in Article VIII hereof.

The Owners own beneficially and of record all of the Units (as defined below), which constitute all of the issued and outstanding membership interests of the Company;

The Owners desire to sell to Buyer, and Buyer desires to purchase from the Owners, the Units upon the terms and conditions set forth herein; and

The Company and the Owners acknowledge that Buyer would not enter into this Agreement but for the Owners agreeing to the terms of Section 3.5 hereof.

In consideration of the mutual covenants, agreements and understandings contained herein and intending to be legally bound, the Parties agree as follows:

1.1    Purchase and Sale of the Units. Upon the terms and subject to the conditions contained herein, on the Closing Date, each Owner agrees to sell, and hereby sells, assigns and transfers, to Buyer, free and clear of all Liens, and Buyer agrees to purchase, and hereby purchases from each Owner, all of such Owner’s issued and outstanding membership interests in the Company, which membership interests are as set forth on Schedule 1.1 hereto (the “Units”). Any other unit or membership interest held in the treasury of the Company, each unit of any other class of membership interests of the Company (other than the Units), and any debt or other securities convertible into or exercisable for the purchase of units of the Company, issued and outstanding immediately prior to the Closing, shall be cancelled without payment of any consideration therefor and without any conversion thereof.

1.2    Purchase Price.

(a)    Purchase Price. The total purchase price for the Units will be an amount equal to the sum of: (i) One Million Seven Hundred and Twenty Thousand Dollars ($1,720,000) (the “Cash Amount”), plus (ii) the Milestone Payments, if any (collectively, the “Purchase Price”), as adjusted pursuant to Article VII below.

(b)    Closing Payment and Assumptions. At Closing, Buyer will:

(i)    direct payment of an amount equal to the Company’s Indebtedness as set forth on Schedule 1.2(b)(i) hereof as of the Closing Date pursuant to payoff letter(s) in form reasonably acceptable to Buyer which will cause the release of all Liens (if any) on the Assets (the “Indebtedness Amount”);

(iii)    pay to the Owners via check or wire transfer of immediately available funds to the accounts or addresses designated by the Representative the sum of the following (the “Closing Cash Payment”), which shall be paid to the Owners pro rata based on their ownership of the Units reflected on Schedule 1.1:

b.    the Indebtedness Amount, minus

c.    the Legal Fees Amount in excess of $40,000.

(c)    Milestone Payments. Following Closing, to the extent that the Milestones described in Section 1.3 hereof are achieved such that a payment is due and payable, Buyer shall pay to the Owners, pro rata based on their ownership of the Units reflected on Schedule 1.1, the payments in respect of the Milestones (“Milestone Payments”) as described in Section 1.3. Notwithstanding the foregoing, in the event a Milestone Payment becomes payable due to a Change of Control, then Buyer may, at its option, and in lieu of actually issuing the shares of Buyer Common Stock to which the Owners would be entitled upon the achievement of the First Milestone or Second Milestone, as applicable (the “Milestone Shares”), satisfy such Milestone Payments by providing each Owner with the right to receive the same amount and kind of securities, cash or property as each Owner would have been entitled to receive upon the occurrence of such Change of Control as if such Owner had been, immediately prior to such Change of Control, the holder of the Milestones Shares.

(d)    Purchase Price Obligations. Upon payment of the respective portion of the Purchase Price (including any Milestone Payments) to the accounts or addresses designated by the Representative, as applicable, Buyer shall have no further liability or

obligation to distribute such respective portion of the Purchase Price to any Owner, and the Representative shall be solely responsible for distribution thereof to the Owners and for the payment of any costs and expenses related to such distribution.

1.3    Milestones.

(a)    First Milestone. Upon the earlier to occur of (i) the later of (A) six (6) months following the Closing Date, and (B) the Date of Enrollment of the first patient in the first Clinical Trial, (ii) a Change of Control, (iii) entry into of a Strategic Collaboration Agreement by Buyer or an Affiliate thereof, or (iv) termination of the BioVascular License Agreement, Buyer shall issue to the Owners, in the case of a Change of Control, immediately prior to closing of such Change of Control, and otherwise within one (1) business day of the occurrence of such event, an aggregate of two million (2,000,000) shares of Buyer Common Stock, subject to adjustments in accordance with Section 1.3(c) hereof, as applicable (the “First Milestone”).

(b)    Second Milestone. Upon the earlier to occur of (i) the Date of Enrollment of the first patient in the first Phase 3 Clinical Trial, (ii) the acceptance for filing by the FDA of a New Drug Application submitted by or on behalf of Buyer or an Affiliate or licensee or development partner thereof in respect of the Product Candidate, (iii) a Change of Control, so long as Buyer or an Affiliate has not terminated the development of the Product Candidate and terminated the BioVascular License Agreement, or (iv) entry into of a Strategic Collaboration Agreement by Buyer or an Affiliate thereof, Buyer shall issue to the Owners, in the case of a Change of Control, immediately prior to closing of such Change of Control, and otherwise within one (1) business day of the occurrence of such event, an aggregate of two million (2,000,000) shares of Buyer Common Stock, subject to adjustments in accordance with Section 1.3(c) hereof, as applicable (the “Second Milestone”).

(c)    Stock Consideration Adjustments.

(i)    The aggregate number of shares issued to the Owners in respect of the First Milestone or the Second Milestone, as applicable, shall in each case, be increased or decreased, as applicable, if, and only if: (x) the Average Closing Price of one share of Buyer Common Stock (1) with respect to a Change of Control, on the day of the first public announcement or public filing relating to such Change of Control, or (2) with respect to any other event resulting in the corresponding Milestone Payment becoming due and payable, the day on which the applicable Milestone is achieved, is less than $4.84 per share (as appropriately adjusted pursuant to Section 1.3(c)(ii) below), then Buyer shall issue to the Owners the number of shares of Buyer Common Stock equal to, in the aggregate, Nine Million Six Hundred and Eighty Thousand Dollars ($9,680,000) divided by such Average Closing Price (rounded to the nearest whole share); or (y) the Average Closing Price of one share of Buyer Common Stock (1) with respect to a Change of Control, on the day of the first public announcement or public filing relating to such Change of Control, or (2) with respect to any other event resulting in the corresponding Milestone Payment

becoming due and payable, the day on which the applicable Milestone is achieved, is greater than $6.84 per share (as appropriately adjusted pursuant to Section 1.3(c)(ii) below), then the Buyer shall issue to the Owners the number of shares of Buyer Common Stock equal, in the aggregate, to Thirteen Million Six Hundred and Eighty Thousand Dollars ($13,680,000) divided by such Average Closing Price (rounded to the nearest whole share). Notwithstanding the foregoing, in no event shall the aggregate number of shares of Buyer Common Stock issuable with respect to each of the First Milestone or Second Milestone exceed 3,000,000 shares of Buyer Common Stock.

(ii)    The number of shares issuable or issued to the Owners pursuant to any provision hereunder and any determination of Average Closing Price shall be subject to appropriate adjustment by virtue of any stock split, stock dividend, combination, recapitalization or similar event affecting Buyer Common Stock generally.

(iii)    Notwithstanding anything to the contrary contained herein, under no circumstances shall Buyer be permitted to satisfy any Milestone Payment with shares of Buyer Common Stock unless such issuance of Buyer Common Stock has been approved by the requisite vote of Buyer’s stockholders in accordance with Rule 5635(a) of the NASDAQ Listing Rules. If Buyer is prohibited or otherwise restricted from distributing Buyer Common Stock, or Buyer otherwise determines that an issuance of Buyer Common Stock is not desirable, it shall not be relieved of its obligation to make the applicable Milestone Payment and such payment shall be made all in cash or in a combination of cash and Buyer Common Stock, as determined by Buyer in its sole discretion. The amount of any cash payment required to be made pursuant to this Section 1.3(c)(iii) shall be determined by multiplying (1) the number of shares of Buyer Common Stock in lieu of which such cash payment is being made, by (2) the Fair Market Value of one share of Buyer Common Stock with respect to the business day on which the applicable cash payment will be made (or the next succeeding business day, if such cash payment will be made other than on a business day).

(d)    Registration Rights. Any shares of Buyer Common Stock received by the Owners pursuant to the First Milestone or Second Milestone hereunder, as applicable, shall be subject to the rights and obligations set forth in a Registration Rights Agreement by and between Buyer and the Owners (the “Registration Rights Agreement”).

(e)    Non-Transferability of Rights. None of the rights of any Owner to receive the First Milestone Payment or the Second Milestone Payment shall be assignable or transferable except through a testamentary disposition, by the laws of descent and distribution upon the death of such Owner, as applicable, or as otherwise permitted in the Registration Rights Agreement. Any attempted assignment, transfer, conveyance, or other disposition (other than as aforesaid) of any interest in the rights of any Owner to receive the First Milestone Payment or the Second Milestone Payment shall be void.

(f)    Third Milestone. Upon the FDA’s written approval of a New Drug Application in respect of the Product Candidate submitted by or on behalf of Buyer or an Affiliate or licensee or development partner thereof, Buyer shall pay to the Owners an aggregate amount equal to Three Million Dollars ($3,000,000) in cash by check or wire transfer of immediately available funds to one or more accounts or addresses designated by the Representative (the “Third Milestone”).

From and after the Closing and continuing for so long as any payments may become payable under this Section 1.3, Buyer shall, or Buyer shall cause one or more of its Affiliates to, (i) use its (or their) Commercially Reasonable Efforts to achieve the First Milestone on or before the first anniversary of the Closing Date, and (ii) otherwise use its (or their) Commercially Reasonable Efforts to develop the Product Candidate, including, without limitation, with respect to the Company’s performance under the BioVascular License Agreement. In the event that the Buyer, or one or more of its Affiliates, has not achieved the First Milestone on or before the first anniversary of the Closing Date (the “First Milestone Deadline”), Buyer shall be required to make the Milestone Payment in respect of the First Milestone on such date; provided, however, that in the event of [**********************************************************************************************************************************************] (each, a “Delay Event”), the First Milestone Deadline will be extended by an amount of time equal to the duration of such Delay Event.

(h)    Withholding. Buyer will be entitled to deduct and withhold from the final Purchase Price including, for the avoidance of doubt, any Milestone Payment, any withholding taxes or other amounts required under the Code or any applicable Law to be deducted and withheld. To the extent that any such amounts are so properly deducted or withheld, such amounts will be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

1.4    Post-Closing Cooperation. Each Owner agrees from time to time after the Closing Date, at Buyer’s reasonable request, to execute, acknowledge, and deliver to Buyer such other instruments of conveyance and transfer and will take such other actions and execute and deliver such other documents, certifications, and further assurances as Buyer may reasonably require in order to vest more effectively in Buyer, or to put Buyer more fully in possession of, all membership or other equity interests of the Company and any of the Company’s rights or assets used in the Business.

(i)    Tax Periods Beginning Before and Ending After the Closing Date. Buyer shall prepare or cause to be prepared and timely file or cause to be timely filed any Tax Returns of the Company for Tax periods that begin before the Closing Date and end after the Closing Date (“Straddle Tax Periods”).

(j)    Payment of Taxes. The Owners shall be responsible for and shall indemnify Buyer from and against, any Tax of the Company that is attributable to a Pre-Closing Tax Period or to that portion of Straddle Tax Period that ends on the Closing Date, in each case to the extent that such Tax exceeds the amount (if any) reflected as a current liability for such Tax in the Unaudited Balance Sheet (as defined below). Within five (5) days prior to the due date for the payment of any such Tax, if the amount of such Tax for which the Owners are responsible pursuant to this Section 3.3 exceeds the amount reflected as a current liability for such Tax in the Unaudited Balance Sheet, the Owners shall pay to Buyer an amount equal to such excess.

3.4    Non-Competition and Non-Solicitation by the Owners.

(a)    Non-Competition. For a period of [***] years after the Closing Date, each Owner (except with respect to performance of an Owner’s obligations under the Consulting Agreements and any other agreements between an Owner and the Company or Buyer, as applicable) will not, directly or indirectly, (i) engage in [***] (a “Competing Business”) , or (ii) invest in, own, manage, operate, finance, control, advise, render services to or guarantee the obligations of any Person engaged in or planning to become engaged in any Competing Business; provided, however, that each Owner may purchase or otherwise acquire up to (but not more than) [***]% of any class of the securities of any Person engaged in or planning to become engaged in a Competing Business (but may not otherwise participate in the activities of such Person).

(b)    Non-Solicitation and Non-Hire. For a period of five (5) years after the Closing Date, each Owner will not, directly or indirectly:

(i)    solicit the business of any Person who is a customer of Buyer or its Affiliates with respect to a Competing Business;

(ii)    cause, induce or attempt to cause or induce any customer, supplier, licensee, licensor, franchisee, employee, consultant or other business relation of Buyer or its Affiliates (A) to cease doing business with such parties, (B) to deal with any competitor of Buyer or its Affiliates, or (C) in any way interfere with its relationship with such parties, in the case of (B) and (C), in connection with a Competing Business;

(iii)    cause, induce or attempt to cause or induce any customer, supplier, licensee, licensor, franchisee, employee, consultant or other business relation of the Company on the Closing Date or within the year preceding the Closing Date (A) to cease doing business with Buyer or its Affiliates, (B) to deal with any competitor of Buyer or its Affiliates, or (C) in any way interfere with its relationship with such parties, in the case of (B) and (C), in connection with a Competing Business; or

(iv)    hire, retain or attempt to hire or retain any employee of Buyer or its Affiliates or in any way interfere with the relationship between Buyer and its Affiliates and any of their respective employees.

(c)    Modification of Covenant. If a final judgment of a court or tribunal of competent jurisdiction determines that any term or provision contained in this Section 3.4 is invalid or unenforceable, then the Parties agree that the court or tribunal will have the power to reduce the scope, duration or geographic area of the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision. This Section 3.4 will be enforceable as so modified after the expiration of the time within which the judgment may be appealed. Each Owner acknowledges this Section 3.4 is reasonable and necessary to protect and preserve Buyer’s and its Affiliates’ legitimate business interests and that such party will not challenge the enforceability of such restrictions.

3.5    Confidentiality by Owners. Each Owner will (i) for a period of five (5) years from the Closing Date, keep confidential and not disclose to others, all proprietary, non-public information of Buyer and the Company (collectively, the “Protected Information”) and (ii) not use any of the Protected Information for such Owner’s own direct or indirect benefit, or the direct or indirect benefit of any third party, except that such Owner may use such information to the extent necessary to perform its duties and obligations, or to enforce such Owner’s rights, under this Agreement or any other agreement between an Owner and Buyer, as applicable. The foregoing shall not prohibit disclosures compelled to be made by any requirement of Law or pursuant to any legal, regulatory or investigative proceeding before any court, or governmental or regulatory authority, agency or

commission so long as such Owner provides prior written notice to Buyer so that Buyer may seek a protective order or other remedy to protect the confidentiality of the Protected Information and/or waive such Owner’s compliance with this Section 3.5, provided that all such information so disclosed (other than in a way which makes it generally available to the public) shall remain Protected Information for all other purposes. If such protective order, other remedy or waiver is not obtained by the time such Owner is required to comply, such Owner may furnish only that portion of the Protected Information that it is legally compelled, in the opinion of counsel, to disclose and shall request, at Buyer’s expense, that such Protected Information be accorded confidential treatment (if such procedure is available), including redaction of any payment terms specified herein. Each Owner further agrees to take appropriate measures to prevent any such prohibited disclosure of Protected Information by his, her or its present and future employees, officers, agents, subsidiaries, or consultants. Notwithstanding the foregoing, no data or information constitutes “Protected Information” if such data or information is publicly known and in the public domain through means that do not involve a breach by an Owner of any covenant or obligation set forth in this Agreement or any other agreement between an Owner and the Buyer, as applicable.

3.6    Confidentiality by Buyer. Except as required pursuant to any applicable Laws, from and after the Closing Date, Buyer shall not intentionally disclose, and shall not permit any of its Affiliates to disclose intentionally, any documents or other information related to a Third-Party Claim, the defense of which has been assumed by an Owner pursuant to Section 7.3(a).

3.7    Enforcement of Covenants. The Parties agree that the remedy of damages at law for the breach of any of the covenants contained in Section 3.4 and Section 3.5 is an inadequate remedy and that each Owner will not challenge the enforceability or reasonableness of the covenants set forth in Section 3.4 or Section 3.5 hereof. In recognition of the irreparable harm that a violation by the Owner of any of the covenants, agreements or obligations arising under Section 3.4 or Section 3.5 would cause Buyer or its Affiliates, each Owner agrees that in addition to any other remedies or relief afforded by law, an injunction against a violation or violations may be issued against the Owner without posting a bond or other security. In the event of an action to enforce the covenants in Sections 3.4 and 3.5, the prevailing party as finally determined by a court of competent jurisdiction will be entitled to be reimbursed for actual attorney’s fees incurred by such party with respect to such action. Should any Owner violate any of the terms of the restrictive covenant obligations set forth in Section 3.4 or Section 3.5 hereof, the period of the obligation at issue will be extended by the period of time that such Owner (as applicable) was in violation of such obligation.

(ix)    The Owners, severally and not jointly (based on each such Owner’s pro rata ownership of the Units reflected on Schedule 1.1), agree that they will indemnify, defend and hold harmless the Buyer Indemnified Parties from, against and in respect of any Losses arising out of, resulting from or in connection with: (i) any breach of any representation or warranty made by the Company or the Owners contained in Article IV of this Agreement or in any certificate delivered on behalf of the Company in connection herewith; (ii) the breach of any covenant or agreement of the Company made in this Agreement; and (iii) any Taxes owed by the Company that are the responsibility of the Owners pursuant to Section 3.3 hereof.

(c)    Limitations on Indemnification. Notwithstanding anything to the contrary herein:

(i)    No Owner will be liable for indemnification under either Section 7.2(b)(i) and 7.2(b)(ii) unless the aggregate amount of Losses under such Sections exceeds Thirty-Seven Thousand and Five Hundred Dollars ($37,500) (the “Threshold”), at which time the Owner or Owners, as applicable, will be obligated to indemnify the Buyer Indemnified Parties, with respect to the aggregate amount of all such Losses under such Sections from the first dollar. Notwithstanding the foregoing, the Threshold will not apply to any claim arising out of a breach of a Fundamental Rep, a SOL Rep or fraud or intentional misrepresentation.

(ii)    The total amount of indemnification payments that an Owner can be required to make to the Buyer Indemnified Parties pursuant to this Agreement shall not exceed, at any time, the amount of fifty percent (50%) of the value of any unpaid Milestone Payments which then become due and payable by Buyer to such Owner in accordance with the terms of this Agreement (the “Cap”). For purposes of the preceding sentence, the value of any cash payments to such Owner shall be the dollar amount thereof, and the value of a share of Buyer Common Stock issued to such Owner shall be the Fair Market Value of one share of Buyer Common Stock with respect to the business day on which the Milestone that resulted in the obligation to issue such Buyer Common Stock to such Owner is achieved (or the next succeeding business day, if such Milestone is achieved other than on a business day). Notwithstanding the foregoing, the Cap will not apply to any claim arising out of fraud or intentional misrepresentation.

(iii)    An Indemnified Party's ability to seek indemnity will not be affected by any investigation, inquiry, knowledge, or examination (whether actual,

constructive or imputed) by the Party seeking indemnification with respect to the accuracy or inaccuracy of or compliance with or performance of, any representation, warranty, covenant, agreement or obligation.

(iv)    The amount of any Losses for which indemnification is provided for under this Agreement shall be reduced by (i) any amounts actually received by an Indemnified Party as a result of any indemnification, contribution or other payment by any third party, (ii) Tax benefits actually realized by an Indemnified Party in respect of the Losses giving rise to such indemnification, and (iii) any insurance proceeds or other amounts actually recovered or received by the Indemnified Party from third parties with respect to such Losses. If an Indemnified Party recovers any amount with respect to any Loss that was previously satisfied by an Indemnifying Party such Indemnified Party shall promptly pay such amount to the Indemnifying Party.

7.3    Indemnification Procedures.

(o)    Third Party Claims.

(i)    If the facts that give rise to any indemnification hereunder will involve any actual or threatened claim or demand (hereinafter referred to as a “Third-Party Claim”) by a party other than a Party hereto, its affiliates, or their respective successors or assigns, the Party entitled to indemnification (the “Indemnified Party”) will give the Party obligated to provide indemnification hereunder (the “Indemnifying Party”) written notice of such claim (the “Third-Party Notice”), including the nature and basis of such Third-Party Claim and the amount of Losses thereof to the extent known, promptly after the Indemnified Party will have received notice thereof from the third-party making such claim. Such Third-Party Notice shall be accompanied by copies of all relevant documentation with respect to such Third-Party Claim, including any summons, complaint or other pleading that may have been served, any written demand or any other document or instrument. The Indemnified Party’s failure or delay in providing the Third-Party Notice will not relieve the Indemnifying Party of its obligations under this Article VII (provided that such Third-Party Notice is received by the Indemnifying Party prior to the expiration of the Survival Period applicable to the underlying claims) except to the extent that the Indemnifying Party is materially prejudiced as a result thereof.

(ii)    The Indemnifying Party will have twenty (20) business days from receipt of the Third-Party Notice to provide the Indemnified Party with notice that it wishes to assume the defense of the Third-Party Claim, in which event the Indemnified Party will have the right to participate in the defense at its own expense. If the Indemnifying Party fails to give the Indemnified Party timely notice, the Indemnified Party will have the right to defend against the Third-Party Claim.

(iii)    If the Indemnifying Party assumes the defense of a Third-Party Claim, the Indemnifying Party will not agree to any settlement, compromise or discharge of the Third-Party Claim without the Indemnified Party’s prior written consent (not to be unreasonably conditioned, withheld or delayed), unless such settlement, compromise or discharge includes an unconditional release of the Indemnified Party from all liability in respect of such claim. If the Indemnifying Party does not assume the defense of the Third-Party Claim, the Indemnified Party may make any settlement, compromise or discharge of the Third-Party Claim without the Indemnifying Party’s prior written consent and seek indemnification pursuant to this Article VII for Losses resulting from such Third-Party Claim in accordance with the provisions, and subject to the limitations, of this Article VII.

(iv)    Notwithstanding anything herein to the contrary, Indemnifying Party will not have the right to assume or continue the defense or handling of such Third-Party Claim unless: (i) the Indemnifying Party will unconditionally agree in writing that it is liable for indemnifying the Indemnified Party for all Losses arising out of such Third-Party Claim in accordance with the provisions, and subject to the limitations, of this Article VII, (ii) the claim does not relate to taxes, criminal or regulatory action, and (iii) the Indemnifying Party conducts the defense actively and diligently.

(v)    The parties shall, in connection with the defense of any Third-Party Claim, make available to each other and their counsel and accountants all books and records and information reasonably related to such Third-Party Claim, keep each other fully apprised as to the details and progress of all proceedings relating thereto and render to each other such assistance as may be reasonably required for the proper and adequate defense of any Third-Party Claim; provided, that the covenants and agreements contained in this Section 7.3(a) shall in no event be, or be deemed to be, a waiver by any party of any right to assert the attorney-client or other applicable privilege.

(p)    Direct Claims

(i)    Any Indemnified Party seeking indemnification hereunder (the “Claimant”) (other than for a Third-Party Claim which is governed by Section 7.3(a) above) must give the Indemnifying Party from whom indemnification is claimed prompt written notice of the claim for Losses (a “Demand”) stating the aggregate amount of the Losses or a good faith estimate thereof, in each case to the extent known or determinable at such time. The Indemnified Party’s failure or delay in providing the Demand will not relieve the Indemnifying Party of its obligations under this Article VII (provided that such Demand is received by the Indemnifying Party prior to the expiration of the Survival Period applicable to the underlying claims) except to the extent that the Indemnifying Party is materially prejudiced as a result thereof.

(ii)    Upon receipt of a Demand by an Indemnifying Party, such Indemnifying Party shall have twenty (20) business days (the “Indemnity Notice Period”), to review and respond by written notice to such Demand (the “Return Notice”) to the Claimant. If the Return Notice does not contest the Demand, or if no Return Notice is delivered to the Claimant by the expiration of the Indemnity Notice Period, then, the Demand shall be conclusively determined in the Indemnified Party’s favor for purposes of this Article VII, and the Indemnified Party shall be indemnified by the Indemnifying Party for the amount of the Losses stated in such Demand on demand or, in the case of any notice in which the Losses (or any portion thereof) are estimated, on such later date when the amount of such Losses (or such portion thereof) becomes finally determined.

(iii)    If the Return Notice given by the Indemnifying Party disputes the claim or claims asserted in a Demand or the amount of Losses thereof (a “Disputed Claim”), then the Claimant and the Indemnifying Parties shall make a reasonable good faith effort to resolve their differences for a period of twenty (20) business days following the receipt by the Claimant of the Return Notice asserting a Disputed Claim. If the Indemnifying Party and the Indemnified Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both such parties. If no such agreement can be reached after good faith negotiation within twenty (20) business days after delivery of a Return Notice, the matter set forth in the applicable Demand will be resolved in accordance with Section 9.7 hereof.

7.4    Offset. Buyer will have the right to set off the indemnification obligations of the Owners pursuant to, and subject to the limitations of, this Article VII against the Milestone Payments; provided, that in the event that Buyer proposes to offset any such amount or right against the Milestone Payments, (a) Buyer shall provide prior written notice of the proposed offset to the Representative specifying in reasonable detail the actual amount of Losses, or Buyer’s good faith, reasonable estimate of such Losses, and the proposed offset and basis thereof and (b) Buyer shall be obligated to pay to the Owners any such amount that is not subject to a pending, or finally determined, offset claim pursuant to this Section 7.4. Upon final determination of the actual amount of Losses and corresponding offset permitted pursuant to this Article VII, Buyer promptly, but in any event within five (5) business days, shall pay to the Owners the excess of the value of any amounts previously withheld pursuant to this Section 7.4 over the actual amount of Losses subject to indemnification hereunder. The maximum number of shares subject to offset pursuant to this Section 7.4 shall be equal to 50% of the aggregate number of shares issuable to the Owners upon achievement of the applicable Milestone then subject to offset as determined in accordance with Section 1.3 hereof. For purposes of determining the number of shares of Buyer Common Stock required to satisfy any indemnifiable Losses of Indemnified Parties, each share of Buyer Common Stock shall be valued at the Fair Market Value of one share of Buyer Common Stock with respect to the business day on which Buyer makes such offset following final determination of the actual amount of Losses (or the next succeeding business day, if such offset is to be made other than on a business day). The Owner’s indemnification obligations pursuant to this Article VII shall be satisfied exclusively by set off against the Milestone Payments pursuant to this Section 7.4. Unless and until

any shares of Buyer Common Stock subject to offset pursuant to this Section 7.4 actually are issued to the Owners and no longer subject to offset, such shares shall remain the property of Buyer.

7.5    Sole and Exclusive Remedy. Except with respect to claims based on fraud or intentional misrepresentation and the right of a Party to seek specific performance for a breach or threatened breach of covenant, the indemnification rights of the Indemnified Parties under this Article VII shall be the sole and exclusive remedy of the Indemnified Parties with respect to claims resulting from or relating to this Agreement.
