(ii) If at any time following the Technology Closing Date but prior to the Manufacturing Closing, Seller shall have delivered to Purchaser an aggregate of 250,000 cubic centimeters of Product (including, for avoidance of doubt, any Product delivered in satisfaction of the First Delivery Threshold) (the “Second Delivery Threshold”) in accordance with the terms and provisions of, and subject to the specifications set forth in, the Manufacturing Agreement, Purchaser shall pay to Seller Five Million Dollars ($5,000,000) (the “Second Milestone Payment”).

(iv) If prior to the Manufacturing Closing, Seller shall have delivered to Purchaser an aggregate of 275,000 cubic centimeters of Product (including, for avoidance of doubt, the Product delivered pursuant to the Second Delivery Threshold) in accordance with the terms and provisions of, and subject to the specifications set forth in, the Manufacturing Agreement, at the Manufacturing Closing, Purchaser shall pay to Seller Five Million Dollars ($5,000,000) (the “Fourth Milestone Payment”).

If any payment under this Section 1.5(a) is made in the form of Purchaser Common Stock, then on the date of such payment Purchaser shall provide to Seller (I) a certificate from a duly authorized officer of Purchaser certifying that as of the date of such issuance (x) the Purchaser Common Stock so issued has been duly authorized and is validly issued, fully-paid and non-assessable and, (y) the provisions of Rule 144(c) of the Securities Act, are satisfied and (II) a legal opinion from Purchaser’s legal counsel that such Purchaser Common Stock has been duly authorized and validly issued, is fully paid and non-assessable and that the holding period set forth in Rule 144(b) of the Securities Act has been satisfied. If Purchaser is unable to satisfy the requirement set forth in the immediately preceding sentence, Seller shall be under no obligation to accept Purchaser Common Stock as payment for the Applicable Milestone Payment and Purchaser shall make such Applicable Milestone Payment in the form of cash, in United States dollars of immediately available funds.

(b) Time for Determination; Dispute Mechanism.

(i) As soon as reasonably practicable following each date on which a Milestone is achieved and in any event within five (5) business days of the achievement

of any such Milestone, Purchaser shall pay to Seller the Applicable Milestone Payment for such Milestone; provided, however, that in no event shall Purchaser be liable for the payment of, and Seller shall not be entitled to, any Applicable Milestone Payment for any Milestone that is not achieved on or before the applicable Milestone Expiration Date. At all times following the Manufacturing Closing Date and prior to payment by Purchaser to Seller of the Sixth Milestone Payment pursuant to Section 1.5(a)(vi) hereof, Purchaser shall, as soon as reasonably practicable following each December 31 during such period, deliver to Seller Purchaser’s calculation of the cumulative Net Sales for the period commencing on the day immediately following the Manufacturing Closing Date and up to and including each such December 31.

(ii) If Seller believes that it is entitled to payment of all or any portion of an Applicable Milestone Payment hereunder which Seller has not received within five (5) business days following the achievement of the Milestone for which payment is due, Seller may, not later than twelve (12) months following the achievement of such Milestone, deliver to Purchaser a notice setting forth Seller’s determination that all or a portion of such Applicable Milestone Payment is due under this Agreement (the “Milestone Assessment Notice”). If Seller does not deliver to Purchaser a Milestone Assessment Notice within such twelve (12) month period, then Seller shall have been deemed to agree that the Milestone has not been met and no payment with respect to such Milestone is due to Seller hereunder and Seller shall have no further rights to such Applicable Milestone Payment or any portion thereof; provided, however, that Seller’s failure to deliver a Milestone Assessment Notice within such twelve (12) month period with respect to the Sixth Milestone Payment shall not relieve Purchaser of its obligations to pay the Sixth Milestone Payment (if and when earned) unless Purchaser is materially prejudiced by such delay.

(iii) If Purchaser shall object to Seller’s determination that a Milestone has been achieved as set forth in the Milestone Assessment Notice, then Purchaser shall deliver a dispute notice (a “Milestone Dispute Notice”) to Seller within five (5) business days following Seller’s delivery of the Milestone Assessment Notice. If Purchaser delivers a Milestone Dispute Notice to Seller in connection with the Sixth Milestone Payment under Section 1.5(a)(vi), upon Seller’s reasonable request, Purchaser shall provide Seller with such books of account and records and written evidence as Seller shall reasonably request showing Purchaser’s calculation of the Net Sales of the Business and, upon Seller’s reasonable request and upon two (2) business days prior written notice to Purchaser, Seller or its representative may inspect the gross receipts, credits, sales Tax, Tax reports, costs and any other reports, records or documents reasonably requested by Seller and associated with the Business or the Product for the sole purpose of reviewing, and only to the extent necessary to review, Purchaser’s calculation of Net Sales. A representative of Purchaser, on the one hand, and a representative of Seller, on the other, shall attempt in good faith to resolve any such objections within ten (10) business days of the receipt by Seller of the Milestone Dispute Notice.

(iv) If Purchaser and Seller shall be unable to resolve any such dispute within the ten (10) business day period, either Purchaser or Seller by written notice to the other may demand arbitration in accordance with the procedures set forth in Section 9.1 hereof.

(v) If no Milestone Dispute Notice is delivered within the timeframe set forth above, then Seller’s determination that the Milestone has been achieved, and that some or all of the Applicable Milestone Payment is due hereunder, shall be deemed to be accepted and Purchaser shall pay to Seller those amounts set forth in the Milestone Assessment Notice.

(c) Rights of Set-Off. Purchaser shall have the right to withhold and set-off against any amount otherwise due to be paid (but not yet paid) pursuant to this Section 1.5 the amount of any Losses to which any Purchaser Indemnified Party may be entitled under Article VIII hereof or any other agreement entered into pursuant to this Agreement (the “Rights of Set-Off”); provided, however, that the foregoing shall not apply (i) to the same Loss more than once or (ii) to the extent any such Loss is adjusted as provided for in Section 8.4(b) hereof.

(d) Acknowledgement of Seller and Purchaser. Seller and Purchaser acknowledge that (i) (A) upon the Technology Closing and subject to Purchaser’s express obligations under the Manufacturing Agreement, Purchaser has the right to operate the Business and Purchaser’s other businesses in any way that Purchaser deems appropriate in Purchaser’s sole discretion, and (B) subject to Purchaser’s express obligations under the Manufacturing Agreement, Purchaser has no obligation to operate the Business in order to achieve any Milestone or to achieve or maximize any Applicable Milestone Payment, (ii) there is no assurance that the Seller will achieve all or any Milestones or that Purchaser will achieve the Net Sales Threshold, (iii) the parties solely intend the express provisions of this Agreement and the other Transaction Documents to govern their contractual relationship, (iv) the right of the Seller to payment of any Applicable Milestone Payment, if any, shall not bear any interest unless not timely paid, and (v) the right of the Seller to a portion of any Applicable Milestone Payment, if any, shall not be represented by a certificate or other instrument, shall not represent an ownership interest of Seller in Purchaser or the Business and shall not entitle Seller to any rights common to any holder of any debt or equity security of Purchaser. The Seller hereby waives, on its behalf and on behalf of any of its successors and assigns, any fiduciary duty (but, for avoidance of doubt, not any implied covenant of good faith and fair dealing) of Purchaser to Seller, with respect to the matters contemplated by this Section 1.5.

Section 1.6 Withholding. Purchaser shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to Seller such amounts as Purchaser is required to deduct and withhold under the Code, or any provisions of state or local Tax law, with respect to the making of such payment. Purchaser shall notify Seller of the basis for such withholding no less than 10 business days prior to the proposed withholding and shall consider in good faith any views of Seller that such withholding is not required under the Code, or any provisions of state or local Tax law, with respect to the making of such payment.

Section 1.7 Allocation of Purchase Price. The Initial Purchase Price shall be allocated for Tax purposes among the Transferred Assets in accordance with Section 1060 of the Code. Purchaser shall prepare and deliver to Seller for Seller’s approval, a proposed allocation of the Initial Purchase Price prepared in accordance with the foregoing within 45 days of the Technology Closing; provided, that if Seller withholds its approval to such allocation, Purchaser and Seller shall negotiate in good faith to agree upon the allocation of the Purchase Price within 30 days of Seller’s receipt of Purchaser’s proposed allocation. Each of Purchaser and Seller shall

file IRS Form 8594 with its Federal income Tax Return consistent with such allocation as determined in accordance with the immediately preceding sentence for the Tax year in which this Agreement is consummated. Seller and Purchaser shall report all Tax consequences of the transactions contemplated by this Agreement in a manner consistent with such allocation, and not take any position inconsistent therewith upon examination of any Tax Return, in any refund claim, in any litigation or investigation or otherwise.

ARTICLE II.
REPRESENTATIONS AND WARRANTIES OF SELLER

Seller represents and warrants to Purchaser as of the date hereof as follows:

Section 2.1 Organization, Good Standing and Authority. Seller is duly formed, validly existing and in good standing under the laws of the State of Delaware, and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, except where failure to be qualified or to be in good standing would not materially and adversely affect the Business.

(b) This Agreement and the other Transaction Documents to which it is a party have been approved by all necessary corporate action of Seller and no other corporate proceedings on the part of Seller and, except for the Stockholder Approval, no corporate proceedings on the part of Seller’s stockholders are necessary to authorize the execution and delivery of this Agreement or any other Transaction Document, or the consummation of the transactions contemplated hereby or thereby, under the Delaware General Corporation Law, the Seller Organizational Documents or otherwise.

Section 2.3 Due Execution and Delivery. Seller has all necessary power and authority to execute and deliver this Agreement and the other Transaction Documents to which it is a party and each instrument required hereby and thereby to be executed and delivered by it, and, prior to the Technology Closing, will have all necessary power and authority to carry out its obligations hereunder and thereunder. Seller has duly executed and delivered this Agreement and assuming the due authorization, execution and deliver of this Agreement by Purchaser, this Agreement constitutes (and, when executed and delivered, the Transaction Documents to which it is a party will constitute) the legal, valid and binding obligations of Seller enforceable against it in accordance with its terms, except that such enforcement (a) may be limited by bankruptcy, insolvency, moratorium or similar laws affecting creditors’ rights generally, and (b) is subject to

the availability of equitable remedies, as determined in the discretion of the court before which such a proceeding may be brought.

Section 2.4 Title and Sufficiency of Transferred Assets.

Notwithstanding the foregoing, if at any time prior to obtaining the Stockholder Approval (i) Seller receives an unsolicited bona fide written Asset Acquisition Proposal that did not result from any breach of this Section 4.6, (ii) the Board of Directors of Seller shall have first determined in good faith that such Asset Acquisition Proposal constitutes a Superior Proposal, (iii) the Board of Directors of Seller shall have first determined in good faith, after consultation with outside counsel, that failure to take such action would result in a breach of its fiduciary duties under the Delaware General Corporation Law (“DGCL”), and (iv) Seller shall have notified Purchaser of such determination (a “Notice of Superior Proposal”) and offered to discuss in good faith with Purchaser (and, if Purchaser accepts, thereafter negotiated in good faith), for a period of no less than five (5) business days, any adjustments in the terms and conditions of this Agreement proposed by Purchaser. If, following such notice and discussions, the Board of Directors of Seller (after consultation with its outside counsel and regionally-recognized independent financial advisor) shall have resolved, after taking into account the results of such discussions and proposals by Purchaser, if any, that the Asset Acquisition Proposal remains a Superior Proposal, then Seller may (A) furnish non-public information with respect to Seller to the person or group making such Asset Acquisition Proposal and their representatives pursuant to a customary confidentiality agreement, and (B) participate in discussions or negotiations with such person or group and their respective representatives regarding such Asset Acquisition Proposal, provided, however, that Seller shall provide or make available to Purchaser any material non-public information concerning Seller, the Business or the Transferred Assets that is provided to the person making such Asset Acquisition Proposal or its representatives which was not previously provided or made available to Purchaser.

(c) Seller will promptly inform Purchaser in writing of any Asset Acquisition Proposal (whether or not such Asset Acquisition Proposal shall be determined by the Board of Directors of Seller to constitute a Superior Proposal) received by them and shall provide to Purchaser the name of such third party and the terms of any such Asset Acquisition Proposal.

If Purchaser fails to respond to the Negotiation Notice within said five (5) business day period, or if Seller and Purchaser fail, after good faith efforts, to enter into a written agreement for such Osteocel XC Transaction within thirty (30) days after delivery of Seller’s Negotiation Notice, then neither Purchaser nor Seller shall have a right or be under any obligation to enter into such Osteocel XC Transaction, and Seller (subject to the right of Purchaser to exercise its right pursuant to Section 4.12(a)) may consummate with a third-party a transaction on terms not materially less favorable to Seller, taken as a whole, than the terms contained in the Negotiation Notice. If Purchaser delivers an Affirmative Response Notice to Seller pursuant to this Section 4.12(b), Purchaser shall provide to Seller a draft definitive agreement for the Osteocel XC Transaction.

Section 4.13 Brand and Trademarks. Except as expressly provided in this Agreement or in the Manufacturing Agreement, Purchaser shall have no rights to any of Seller’s intellectual property other than the Transferred Technology, and Seller shall have no rights to any of Purchaser’s intellectual property.

Section 4.14 Consents. Prior to the Technology Closing Date, Seller shall use its commercially reasonable efforts to obtain in writing and at its own expense all consents and waivers referred to on Schedule 2.5 hereto. To the extent that an attempted assignment or transfer of any Assumed Contract would constitute a breach thereof, this Agreement shall not constitute an assignment or attempted assignment thereof. In such a case, Seller shall establish with Purchaser any back-to-back arrangement reasonably requested by Purchaser in order to provide for Purchaser the benefits intended to be assigned under any such Assumed Contract (subject to the right of any third party thereunder to terminate such Assumed Contract), including, without limitation, the enforcement by Seller for the benefit of Purchaser, at Purchaser’s sole cost and expense, of any and all rights of Seller against a third party to such Assumed Contract arising out of the breach by such third party or otherwise.

Section 4.15 ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Notification.

(a) Seller and Purchaser shall each promptly prepare, execute and file a notification with the United States Justice Department and the Federal Trade Commission as required by the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (“HSR”). Seller and Purchaser shall cooperate with each other in connection with the preparation of such notification, including sharing information concerning sales and ownership and such other information as may be needed to complete such notification, and providing a copy of such notification to the other prior to filing. Each of Seller and Purchaser shall keep all information about the other obtained in connection with the preparation of such notification confidential. Purchaser and Seller shall each pay one-half of the filing fee required under by the regulations promulgated pursuant to HSR. Purchaser and Seller shall promptly inform the other of any material communication between such party and any governmental entity regarding any of the transactions contemplated hereby. If either party received any formal or informal request for supplemental information or documentary material from any governmental entity with respect to the transactions contemplated hereby, then the recipient of such request shall make, or case to be made, as soon as reasonably practicable, a response in compliance with such request and, in making any such response, the responding party shall consider in good faith the views of the other party hereto. Seller and Purchaser covenant and agree that the Technology Closing shall be subject and conditioned upon the receipt of requisite approvals or the expiration of the applicable waiting period under HSR.

(b) Notwithstanding anything in this Agreement to the contrary, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as violative of any federal, state or foreign statutes, rules, regulations, orders or decrees that are designed to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraining o trade (collectively, “Antitrust Laws”), it is expressly understood and agreed that: (i) Purchaser and Seller shall provide information required by law or governmental regulation and shall use commercially reasonably efforts to substantially comply as promptly as practicable with any “second request” for information pursuant to the Antitrust Laws; (ii) Purchaser and Seller shall use their commercially reasonably efforts to resolve such objections, if any, as may be asserted by any governmental entity with respect to the transactions contemplated by this Agreement under Antitrust Laws; provided, however, that (A) neither Purchaser nor Seller shall have any obligation to litigate or contest any administrative or judicial action or proceeding or any decree, judgment, injunction or other order, whether temporary, preliminary or permanent; and (B) Purchaser shall be under no obligation to make proposals, execute or carry out agreements or submit to orders providing for (1) the sale, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Purchaser or any of its affiliates or the Transferred Assets, or (2) the imposition of any limitation or regulation on the ability of Purchaser or any of its affiliates to freely conduct their business or own such assets.

Section 4.16 Public Announcement. Except as required by law, neither party (nor any director, officer, employee or affiliate of either party) shall make any public announcement, whether written or oral, concerning this Agreement or the subject matter hereof without the prior written consent of the other.

Section 4.17 Bulk Sales Laws. Seller shall comply, in connection with transactions contemplated by this Agreement, with any applicable bulk sales laws and any other applicable bulk sales laws with respect to or requiring notice to Seller’s creditors, in effect as of the Technology Closing Date with respect to the Technology Assets and the Manufacturing Closing Date with respect to the Manufacturing Assets.

Section 4.18 Transfer Taxes. All sales or use, transfer, real property gains, excise, stamp, business and occupation, or other similar Taxes, resulting or arising out of or in connection with the consummation of the transactions contemplated hereby (“Transfer Taxes”) and imposed on Seller shall be paid by Seller and Seller shall promptly discharge such Transfer Taxes when due. All Transfer Taxes imposed on Purchaser other than Transfer Taxes resulting from Seller’s breach of this Section 4.19 shall be paid by Purchaser.

Section 4.19 Termination of Certain Contracts. At or prior to the Technology Closing Date, Seller shall deliver to each party to those Contracts identified on Schedule 2.9(c) a notice of termination, which termination shall be effective as of the date set forth opposite each such Contract on Schedule 2.9(c). Notwithstanding the foregoing, Seller shall give any such notice of termination following the Technology Closing Date within two (2) business days of receipt of a written request of Purchaser to earlier deliver such notice of termination. Seller acknowledges that Seller’s failure to comply with the provisions of this Section 4.20 shall be a material breach of this Agreement for purposes of Section 5.2(b) hereof.

Section 4.20 Preparation of Proxy Statement; Stockholder Meeting.

(a) As promptly as reasonably practicable following the date of this Agreement, Seller shall prepare and file with the Securities and Exchange Commission (the “SEC”) a proxy statement relating to the approval of the transactions contemplated by this Agreement by Seller’s stockholders (as amended or supplemented from time to time, the “Proxy Statement”) and Seller shall use its reasonable best efforts to respond as promptly as practicable to any comments of the SEC with respect thereto and to cause the Proxy Statement to be mailed to Seller’s stockholders as promptly as reasonably practicable following the date of this Agreement. Seller shall promptly notify Purchaser upon the receipt of any comments from the SEC or its staff or any request from the SEC or its staff for amendments or supplements to the Proxy Statement and shall provide Purchaser with copies of all correspondence between Seller and its representatives, on the one hand, and the SEC and its staff, on the other hand. Notwithstanding anything to the contrary stated above, prior to filing or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, Seller shall (i) provide Purchaser the reasonable opportunity to review and comment on such document or response prior to any filing of such document or response to any comments of the SEC and consider in good faith Purchaser’s comments, (ii) include in such document or response all comments reasonably proposed by Purchaser with respect to any statement or information specifically relating to the Purchaser.

(b) Seller shall, as promptly as reasonably practicable following the date of this Agreement (taking into consideration regulatory review processes and timing therefore), establish a record date for, duly call, give notice of, convene and hold a meeting of its stockholders (the “Stockholders Meeting”) for the purpose of obtaining the affirmative vote of

the holders of a majority of the outstanding shares of Seller’s common stock, par value $0.001 per share, in favor of approval of the transactions contemplated by this Agreement (the “Stockholder Approval”). Seller shall cause the Stockholders Meeting to be held as promptly as reasonably practicable after the date of this Agreement. Except as set forth in Section 4.6(b), Seller shall, through its board of directors, recommend to its stockholders that they approve this Agreement and the transactions contemplated hereby, and shall include such recommendation in the Proxy Statement (“Seller Board Recommendation”).

(c) Except as set forth in this Section 4.20(c), the Board of Directors of Seller shall not (i) withdraw or modify in a manner adverse to Purchaser, or publicly propose to withdraw or modify in a manner adverse to Purchaser, the Seller Board Recommendation; (ii) approve or recommend any letter of intent, agreement in principle, acquisition agreement, option agreement or similar agreement constituting or relating to, or that is intended to be or would reasonably be likely to result in, any Asset Acquisition Proposal; or (iii) approve or recommend, or publicly propose to approve, endorse or recommend, any Asset Acquisition Proposal. Notwithstanding the foregoing, if, prior to receipt of the Stockholder Approval, the Board of Directors of Seller determines in good faith that an unsolicited bona fide written Alternative Proposal received by Seller constitutes a Superior Proposal (after compliance with the notification and negotiation provisions set forth herein), the Board of Directors of Seller may withdraw, modify or qualify its Seller Board Recommendation (a “Change in Seller Board Recommendation”) and may recommend such Superior Proposal.

Except as set forth in Section 8.6 with respect to third party Actions, in the event of any Purchaser Claim, Purchaser shall notify Seller and such notice shall be in writing and shall describe with reasonable specificity the nature and amount of such Purchaser Claim (a “Purchaser Notice of Claim”). A delay on the part of a Purchaser Indemnified Party in giving Seller a Purchaser Notice of Claim shall relieve Seller from its obligations under this Section 8.1 only to the extent that Seller is materially prejudiced thereby. A Purchaser Notice of Claim may be delivered at any time during the applicable survival period for such claim as set forth in Section 8.3 of this Agreement.

Section 8.2 Indemnification by Purchaser. Purchaser hereby agrees to indemnify, defend and save harmless Seller and its directors, officers, employees, affiliates, agents, advisors, representatives, stockholders and assigns (collectively, the “Seller Indemnified Parties”) from, against and in respect of any and all Losses incurred or suffered by any Seller Indemnified Party arising out of, or related to, the following (each, a “Seller Claim”):

Except as set forth in Section 8.6 with respect to third party Actions, in the event of any Seller Claim, Seller shall notify Purchaser and such notice shall be in writing and shall describe with reasonable specificity the nature and amount of such Seller Claim (a “Seller Notice of Claim”). A delay on the part of a Seller Indemnified Party in giving Purchaser a Seller Notice of Claim shall relieve Purchaser from its obligations under this Section 8.2 only to the extent that Purchaser is materially prejudiced thereby. A Seller Notice of Claim may be delivered at any time during the applicable survival period for such claim as set forth in Section 8.3 of this Agreement.

Section 8.3 Survival. If the Technology Closing occurs, all representations and warranties of Purchaser and Seller contained herein or in any other Transaction Document or document, certificate or other instrument required to be delivered hereunder or thereunder in connection with the transactions contemplated hereby shall survive the Technology Closing and shall continue until eighteen months (18) months after the Manufacturing Closing, provided that the representations and warranties set forth in Section 2.6 (Taxes), Section 2.9(c) (Disposition of Certain Contracts), Section 2.15 (Intellectual Property), Section 2.18 (Authorizations; Regulatory Compliance), Section 2.20 (Environmental), Section 2.22 (Brokers), shall survive until sixty (60) days after the expiration of the applicable statutes of limitations (including any extensions or waivers thereof) (the “Specified Representations”); provided, further, that the representations and warranties on which any Claims for indemnification are based shall continue in effect until final resolution of such claims and such expiration thereof shall not effect the right of any Indemnified Party to seek indemnification for Losses pursuant to Article 8 hereof.

Section 8.4 Limitations. Notwithstanding anything contained in this Agreement to the contrary:

(a) Neither party shall be liable or be obligated to make any payment in respect of Losses suffered by an Indemnified Party under Section 8.1(a) (other than the representations and warranties set forth in Section 2.4 hereof), 8.1(b), 8.2(a) or 8.2(b) hereof (as the case may be) until the aggregate of all Losses suffered by such Indemnified Party under this Article VIII exceeds Two Hundred Fifty Thousand Dollars ($250,000) (the “Basket Amount”); after which such other party shall be entitled to recover all such Losses (subject to the General Cap Amount); provided that in no event shall the aggregate indemnity amount payable by any indemnifying party pursuant to Section 8.1(a), 8.1(b) or 8.2(a) hereof (other than with respect to any Specified Representations) exceed Fifteen Million Dollars ($15,000,000) (the “General Cap Amount”).

(b) Neither party shall be liable or be obligated to make any payment in respect of Losses suffered by an Indemnified Party under (i) Section 8.1(a) with respect to any Specified Representation (other than the representations set forth in Section 2.9(c) hereof), or (ii) Section 8.2(b) (the “Special Cap Liabilities”) until the aggregate of all Losses suffered by such Indemnified Party under this Article VIII exceeds the Basket Amount, after which such other party shall be entitled to recover all such Losses (subject to the Special Cap Amount), provided

that in no event shall the aggregate indemnity amount payable by any indemnifying party with respect to the Special Cap Liabilities and liability under Section 8.1(a) with respect to the representations set forth in Section 2.9(c) hereof, when taken together with all Losses paid or payable to an Indemnified Party pursuant to Section 8.4(a) above, exceed Twenty Million Dollars ($20,000,000) plus any Applicable Milestone Payments that become payable (prior to Purchaser’s Rights of Set-Off) pursuant to Section 1.5 hereof; provided, however, that in no event shall the aggregate indemnity amount for Losses payable by any Indemnifying Party under this Section 8.4(b), when taken together with all Losses paid or payable by an Indemnifying Party pursuant to Section 8.4(a), exceed Thirty Five Million Dollars ($35,000,000) (the “Special Cap Amount”).

(c) Each party’s liability and obligation to make any payment in respect of Losses suffered by an Indemnified Party under (i) Sections 8.1(c) and 8.1(d) or (ii) Sections 8.2(c) and 8.2(d) shall be unlimited.

(d) The amount of any Losses indemnifiable by either party pursuant to this Article VIII shall be adjusted to reflect the value of any insurance proceeds actually received (net of any deductibles, retention or self-insurance) by the Indemnified Party or its successors or assigns in respect of such Losses provided, however, that no Indemnified Party shall have any obligation to pursue such insurance proceeds or recovery from third persons. If any such proceeds or recoveries are received by an Indemnified Party (or any of its affiliates) with respect to any Claims after a party hereto has made a payment to the Indemnified Party with respect to such Claim, the Indemnified Party (or such affiliate) shall pay to such party the amount of such proceeds or recoveries (up to the amount of such party’s payment with respect to such Claim).

(e) No Indemnified Party shall be entitled to recover under this Article VIII an amount in respect of Losses, or otherwise obtain reimbursement or restitution from any party to this Agreement, more than once in respect of the same Loss.

Section 8.5 Resolution of Notice of Claim. Each Purchaser Notice of Claim and Seller Notice of Claim (each, a “Notice of Claim”) delivered hereunder shall be resolved as follows:

(a) If, within thirty (30) days after a Notice of Claim is received by the indemnifying party, the indemnifying party does not contest such Notice of Claim in writing to the Indemnified Party, the indemnifying party shall be conclusively deemed to have consented to the recovery by the Indemnified Party of the full amount of Losses (subject to the limits contained in this Article VIII) specified in the Notice of Claim in accordance with this Article VIII, and the indemnifying party shall be obligated to pay to the Indemnified Party the total amount of Losses set forth in the Notice of Claim within fifteen (15) days following such thirty (30) day period.

(b) Following the delivery of a Notice of Claim to an indemnifying party, the indemnifying party shall be given such access as they may reasonably require during the Indemnified Party’s normal business hours (or such other times as the parties may agree) to those books and records of the Indemnified Party relating to the Claim in the possession of, and/or under the control of, the Indemnified Party, and access to such personnel or representatives of

the Indemnified Party as they may reasonably require for the purposes of determining whether to contest all or any portion of a Notice of Claim.

(c) If the indemnifying party gives the Indemnified Party written notice contesting all or any portion of a Notice of Claim (a “Contested Claim”) within the thirty (30) day period specified in Section 8.5(a) above, then such Contested Claim shall be resolved by either (i) a written settlement agreement or memorandum executed by the Indemnified Party and the indemnifying party or (ii) in the absence of such a written settlement agreement within fifteen (15) days following receipt by the Indemnified Party of the written notice from the indemnifying party, by binding arbitration between the Indemnified Party and indemnifying party in accordance with the terms and provisions of Section 9.1 below. The decision of the arbitrators as to the validity and amount of any claim in any disputed Notice of Claim shall be binding and conclusive upon the parties to this Agreement, and the Indemnified Party shall be entitled to act in accordance with and in reliance on such decision, and the indemnifying party shall be obligated to pay to the Indemnified Party the total amount of Losses as determined by the arbitrator within fifteen (15) days following such decision.

(d) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Seller and Purchaser shall instruct the arbitrators to determine and set forth in judgment of the arbitrators the non-prevailing party to an arbitration and such non-prevailing party shall pay its own expenses, the fees of each arbitrator, the administrative fee of the American Arbitration Association, and the expenses, including, without limitation, the reasonable attorneys’ fees and costs, incurred by the prevailing party to the arbitration. The arbitration panel shall be authorized to determine which party to the arbitration is the prevailing party and which party is the non-prevailing party.

(e) Any amounts owed to any Purchaser Indemnified Party following the resolution of a Purchaser Claim, as determined by this Section 8.5, shall be satisfied, at the sole discretion of Purchaser, by payment of Seller to Purchaser, from any earned but unpaid portion of the Maximum Milestone Amount.

Section 8.6 Third Party Actions. In the event any Action is instituted against an Indemnified Party, which involves a Claim for which indemnification may be sought, the Indemnified Party will, promptly after receipt of notice of any such Action, notify the indemnifying party of the commencement thereof. The failure to so notify the indemnifying party of the commencement of any such Action will relieve the indemnifying party from liability in connection therewith only to the extent that such failure materially and adversely affects the ability of the indemnifying party to defend the interests of the indemnifying party in such Action. Except as set forth on Schedule 8.6 hereto, the Indemnified Party shall have the right to control the defense or settlement of such Action; provided that the indemnifying party and its counsel (at such party’s sole expense) may participate in (but not control the conduct of) the defense of such Action, but only to the extent that such participation does no affect any privilege relating to the Indemnified Party. Any settlement by the Indemnified Party of any such Action with third party claimants, or any judgment by any governmental entity with respect to such Action with third party claimants, shall be determinative of the amount of Losses relating to such matter for purposes of this Article VIII.

Section 8.7 Exclusive Remedy. If the Technology Closing occurs, except for the rights of Purchaser set forth in Section 9.1(b) hereto, following the Technology Closing the right of the parties hereto to demand and receive indemnification pursuant to this Article VIII shall be the sole and exclusive remedy exercisable by a party with respect to this Agreement or the transactions contemplated hereby except for the right to seek specific performance of any of the agreements contained herein, and except in the case of fraud or intentional misrepresentation.

Section 8.8 Reliance. No Indemnified Party shall be required to show reliance on any representation, warranty, certificate or other agreement in order for such Indemnified Party to be entitled to indemnification hereunder.

Section 8.9 Tax Treatment of Indemnity Payments. Any payment pursuant to this Article VIII shall be considered an adjustment to the initial Purchase Price for Tax purposes, to the maximum extent permitted by law.

ARTICLE IX.
MISCELLANEOUS

(a) Any dispute, controversy, difference or claim arising out of, relating to or in connection with this Agreement, any other Transaction Document, any transaction hereunder or thereunder or breach hereof or thereof shall be finally settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (the “Rules”) then in effect by one (1) arbiter appointed with the consent of both Seller and Purchaser (and in the event such consent cannot be obtained within thirty (30) days following the request by Seller or Purchaser for the consent of the other, in accordance with the Rules). The arbiter’s award shall be final and binding, and, in all instances, be subject to the limitations set forth in Article VIII hereof. Judgment upon the award rendered by the arbiter may be entered in any court having jurisdiction thereof. The arbitration shall take place in the ▇▇▇▇ County in the State of Illinois, or such other place as the parties may agree. The arbiter’s award shall be in writing and shall include (i) a provision that the prevailing party in the arbitration shall recover its costs of the arbitration and reasonable attorneys’ fees from the other party, and (ii) the amount of such costs and fees.

(b) Notwithstanding subsection (a), (i) either party may, if it believes that it requires or is entitled to injunctive relief, file a civil action in any court having jurisdiction seeking injunctive relief, (ii) Purchaser shall be entitled to specific performance to remedy any breach by Seller of its representations and warranties contained in Section 2.4 (Title and Sufficiency of Transferred Assets) and the covenants contained in Section 4.1 (Further Assurances) and shall be entitled to file a civil action in any court having jurisdiction seeking such relief and (iii) Purchaser shall be entitled to specific performance and shall be entitled to file a civil action in any court having jurisdiction seeking such relief if Seller is in breach of its obligations under Section 4.6 (No Other Bids) hereof or if following the termination of the Manufacturing Agreement, Purchaser has requested that the Manufacturing Closing take place and the

Manufacturing Assets be transferred to Purchaser in accordance with the terms of this Agreement and Seller has not, within ten (10) business days following such request, delivered and transferred the Manufacturing Assets to Purchaser. Any claim to or demand for monetary damages shall, however, be governed exclusively by the provisions for arbitration set forth in subsection (a).

Section 9.2 Merger Clause. This Agreement, the other Transaction Documents and the agreements, documents and instruments to be executed and delivered in connection herewith and therewith contain the final, complete and exclusive statement of the agreement between the parties with respect to the transactions contemplated herein and all other prior or contemporaneous oral communications (including, for avoidance of doubt, communications in connection with the preparation of this Agreement and the other Transaction Documents) and agreements, and all prior written communications (including, for avoidance of doubt, written drafts of this Agreement and the other Transaction Documents) and agreements, with respect to the subject matter hereof are merged herein and superseded.

No course of dealing and no failure or delay on the part of any party hereto in exercising any right, power or remedy conferred by this Agreement shall operate as a waiver thereof or otherwise prejudice such party’s rights, powers and remedies. The failure of either party to this Agreement to require the performance of a term or obligation under this Agreement or the waiver by the other party to this Agreement of any breach hereunder shall not prevent subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach hereunder. No single or partial exercise of any right, power or remedy conferred by this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

Section 9.4 Notices.
