ARTICLE 5.

BANKRUPTCY COURT MATTERS

5.1 Competing Transaction. This Agreement is subject to approval by the Bankruptcy Court and the consideration by the Seller of higher or better competing bids in respect of all or any part of the Transferred Assets (whether in combination with other assets of the Seller Group or otherwise) in accordance with the terms of the Bid Procedures Order (each, a “Competing Bid”). From the Agreement Date (and any prior time) and until the Closing, the Seller is permitted to, and to cause its representatives to, initiate contact with, solicit or encourage submission of any inquiries, proposals or offers by, any Person (in addition to Purchaser and its Affiliates and representatives) in connection with any sale or other disposition of the Transferred Assets. In addition, the Seller shall have the authority to respond to any inquiries or offers to purchase all or any part of the Transferred Assets (whether in combination with other assets of the Seller Group or otherwise) and perform any and all other acts related thereto which are required under the Bankruptcy Code, the Bid Procedures Order or other Applicable Law, including supplying information relating to the Business and the assets of the Seller Group to prospective purchasers.

5.2 Bankruptcy Court Filings.

(a) Subject to its right to pursue a Competing Bid in accordance with the Bid Procedures Order, the Seller shall diligently pursue the entry by the Bankruptcy Court of the Sale Order, which Sale Order shall provide for the transfer of the Transferred Assets and the Assumed Liabilities to Purchaser free from all successor or transferee Liability to the fullest extent permitted by Section 363 of the Bankruptcy Code. The Seller shall comply (or obtain an Order from the Bankruptcy Court waiving compliance) with all requirements under the applicable provisions of the Bankruptcy Code, the Federal Rules of Bankruptcy Procedure, and the Local Bankruptcy Rules for the Bankruptcy Court in obtaining the entry of the Sale Order. The Seller further covenants and agrees that, after entry by the Bankruptcy Court of the Sale Order, and provided that the Sale Order becomes a Final Order, the terms of any other proposed order submitted by the Seller to the Bankruptcy Court shall not conflict with, supersede, abrogate, nullify or restrict the terms of this Agreement, or in any way prevent or interfere with the consummation or performance of the Transactions. Purchaser agrees that it will promptly take such actions as are reasonably requested by the Seller to assist in obtaining entry of the Sale Order, including by furnishing affidavits or other documents or information for filing with the Bankruptcy Court for the purposes, among others, of providing necessary assurances of performance by Purchaser under this Agreement and demonstrating that Purchaser is a “good faith” purchaser under Section 363(m) of the Bankruptcy Code. In the event, if the entry of the Sale Order shall be appealed, the Seller and Purchaser shall use their respective commercially reasonable efforts to defend such appeal.

(b) Seller shall use commercially reasonable efforts to provide Purchaser with a reasonable opportunity to review and comment upon all motions, applications, and supporting papers relating to the transactions contemplated by this Agreement prepared by Seller or any Affiliates (including forms of orders and notices to interested parties) prior to the filing thereof in the Bankruptcy Cases; provided that the foregoing shall not require the Seller to take any action that would, in Seller’s reasonable business judgment, threaten to harm the overall value to be produced by the Seller’s in-court sale process.

(c) The form of Sale Order submitted by the Seller to the Bankruptcy Court for approval shall be in a form and substance reasonably acceptable to Purchaser.

(d) Seller shall not seek any modification to the Bid Procedures, Bid Procedures Order, or Sale Order by the Bankruptcy Court that are materially adverse to Purchaser without the prior written consent of Purchaser, which such consent shall not be unreasonably withheld.

31

(e) Each of Purchaser and Seller will promptly take such actions as are reasonably requested by the other party to assist in obtaining entry of the Sale Order, including furnishing affidavits or other documents or information for filing with the Bankruptcy Court for purposes, among others, of providing necessary assurances of performance by Seller of its obligations under this Agreement and demonstrating that Purchaser is a good faith buyer under section 363(m) of the Bankruptcy Code.

(f) Seller shall use commercially reasonable efforts to provide appropriate notice of the hearings on the Sale Order to all Persons entitled to notice, including, but not limited to, all Persons that have asserted Liens on the Transferred Assets, all parties to the Assigned Contracts and all taxing authorities in jurisdictions applicable to Seller and as otherwise required by the Bankruptcy Code and bankruptcy rules.

(g) Within five (5) Business Days of the Auction (subject to the Bankruptcy Court’s availability), if Purchaser is the successful bidder at the Auction (or if there is no Auction), Seller will seek entry of the Sale Order by the Bankruptcy Court.

(h) The Seller and Purchaser agree that, in the event that Purchaser is not the winning bidder at an auction undertaken pursuant to the Bid Procedures Order (the “Auction”), and (i) Purchaser submits the Back-Up Bid at the Auction or (ii) the terms of this Agreement are deemed to constitute a Back-Up Bid, then Purchaser shall be obligated to promptly consummate the Transactions upon the terms and conditions as set forth herein, including the payment of the Purchase Price as the same may be increased by Purchaser at the Auction; provided that the Seller gives written notice to Purchaser on or before the Back-up Termination Date, stating that the Seller (A) failed to consummate the sale of the Transferred Assets with the winning bidder, and (B) terminated the purchase agreement with the winning bidder.

5.3 Assumption of Assigned Contracts.

(a) On June 4, 2024, the Seller filed (or caused to be filed) a notice of assumption (the “Assumption Notice”) with the Bankruptcy Court and served such notice on each counterparty to a Contract listed thereon. The Assumption Notice identified all Contracts that the Seller and Purchaser believe may be assumed and assigned in connection with the sale of the Transferred Assets and set forth a good faith estimate of the amount of Cure Amounts applicable to each such Contract (and if no Cure Amount is estimated to be applicable with respect to any particular Contract, the amount of such Cure Amount designated for such Contract shall be “$0.00”). In accordance with the Bid Procedures Order, the Seller reserves the right to supplement such list of Contracts and provide additional notice of assumption.

(b) On or before the date that is three (3) Business Days before the Closing Date (the “Designation Deadline”), Purchaser shall provide to the Seller a Contracts List, which shall identify all Contracts that Purchaser elects to have assumed and assigned to Purchaser on the Closing Date (and with respect to the Existing Manufacturing Contracts, assumed and assigned to Purchaser which will be automatically effective as of the applicable Existing Manufacturing Contract Transfer Date without further notice). For the avoidance of doubt, Purchaser shall be entitled, with the agreement of Seller, to add, or, in the sole discretion of Purchaser, to remove, any Contracts from the Contracts List at any time (or multiple times) prior to the Designation Deadline by providing to the Seller by email a copy of the amended Contracts List. Any Contracts List that Purchaser delivers to the Seller prior to the Designation Deadline shall be deemed to replace and supersede any Contracts List that Purchaser had previously delivered to Seller. For the avoidance of doubt, only those Contracts that are identified on the Contracts List as of the Designation Deadline shall constitute Assigned Contracts and will be assumed by the Seller and assigned to Purchaser pursuant to the Sale Order. The Seller shall file such motions or pleadings as may be appropriate or necessary to assume and assign the Assigned Contracts and to determine the amount of the Cure Amounts; provided that nothing herein shall preclude the Seller from filing one or more motions to reject any Contracts that are not identified on the Contracts List as of the Designation Deadline.

32

(c) Notwithstanding any provision in this Agreement to the contrary, a Contract shall not be an Assigned Contract hereunder and shall not be assigned to, or assumed by, Purchaser to the extent that such Contract is (i) deemed rejected under Section 365 of the Bankruptcy Code, (ii) the subject of an objection to assignment or assumption or requires the consent of any Governmental Authority or other third party (other than, and in addition to, the Bankruptcy Court) in order to permit the assumption and assignment by the applicable Seller to Purchaser of such Contract pursuant to Section 365 of the Bankruptcy Code, and such objection has not been resolved or such consent has not been obtained prior to the thirtieth (30th) day following the Closing Date (as such period may be extended by mutual agreement of Seller and Purchaser), or (iii) terminated by any party thereto other than Seller, or terminates or expires by its terms, on or prior to such time as it is to be assumed by and assigned to Purchaser as an Assigned Contract hereunder and is not continued or otherwise extended upon assumption. In no event shall the failure to assign to Purchaser any Contract in accordance with subsections (i) through (iii) above reduce the Purchase Price payable to Seller or constitute a failure to satisfy the conditions precedent of Seller under Section 8.3.

(d) Subject to the terms of Section 2.5, Section 2.8, Section 5.3(a) and Section 5.3(b), and subject to the entry of an order (which may be the Sale Order) of the Bankruptcy Court authorizing the assignment to Purchaser of the Assigned Contracts, Purchaser shall make provision for the payment of the Purchaser Cure Amounts for Assumed Contracts, and Seller shall make provision for the payment of the Seller Cure Amounts for Assumed Contracts, in cash at Closing in accordance with the Sale Order.

(e) Notwithstanding any provision in this Agreement to the contrary, from and after the date of the Assumption Notice through the Closing Date, the Seller will not reject or take any action (or fail to take any action that would result in rejection by operation of Applicable Law) to reject, withdraw, repudiate or disclaim any Assigned Contract unless (i) Purchaser has provided its prior written consent; or (ii) Purchaser has removed such Assigned Contract from the list of Assigned Contracts.

5.4 Disputed Contracts. In the event of an objection by a Contract counterparty to the Cure Amount asserted by Seller with regard to any Contract on the Contract List (such contract, a “Disputed Contract”), Seller shall either settle the objection of such party or shall litigate such objection under procedures as established by the Bankruptcy Court. In no event shall the Seller settle a Cure Amount objection with regard to any potential Assigned Contract without the express written consent (such consent not to be unreasonably withheld) of Purchaser (with an email consent being sufficient). In the event that a dispute regarding the Cure Amounts with respect to a Contract has not been resolved as of the Closing, the parties shall nonetheless remain obligated to consummate the transactions contemplated by this Agreement. Upon entry of an Order of the Bankruptcy Court (if necessary) determining any Cure Amount and authorizing the assumption and assignment to Purchaser of such Disputed Contract after the Closing, which order shall be in form and substance acceptable to Purchaser (a “Disputed Contract Order”), Purchaser shall have the option to designate the Disputed Contract as an Assigned Contract or an Excluded Contract (regardless of whether such contract was identified on the Contracts List). If Purchaser elects to designate the Disputed Contract as an Excluded Contract, (a) such Disputed Contract shall automatically be deemed to be an Excluded Contract for all purposes under the Sale Order and this Agreement, and (b) Purchaser shall not be obligated to pay any Cure Amount or liabilities associated with such Disputed Contract. If Purchaser elects to designate the Disputed Contract as an Assigned Contract, such Disputed Contract shall be deemed an Assigned Contract for all purposes hereunder and, for the avoidance of doubt, Purchaser shall assume the Disputed Contract and shall be responsible for paying the associated Purchaser Cure Amount (if any) with respect to such Disputed Contract; and (if applicable) Seller shall be responsible for paying all related Seller Cure Amounts; provided, however, that if Purchaser does not designate such Disputed Contract as either an Excluded Contract or an Assigned Contract within five (5) Business Days after the date of the Disputed Contract Order (or such later date as agreed by the Seller and Purchaser), (a) such Disputed Contract shall automatically be deemed to be an Excluded Contract for all purposes under the Sale Order and this Agreement, and (b) Purchaser shall not be obligated to pay any Cure Amount or liabilities associated with such Disputed Contract.

33

5.5 Previously Unknown and Previously Excluded Contracts.

(a) If at any time, prior to the earlier of confirmation of a plan in the Chapter 11 Cases or entry of an order dismissing the Chapter 11 Cases, it is discovered that a Contract material to the operation of the Business should have been identified on the Assumption Notice but was not so listed (any such Contract, a “Previously Unknown Contract”), Seller shall, promptly following the discovery thereof (but in no event later than five (5) Business Days following the discovery thereof), notify Purchaser in writing of such Previously Unknown Contract and provide Purchaser with a copy of such Previously Unknown Contract and the Cure Amount (if any) in respect thereof. Purchaser shall thereafter deliver written notice to Seller (email being sufficient), no later than ten (10) Business Days following such notice of such Previously Unknown Contract from Seller, if Purchaser elects for such Previously Unknown Contract to be an Assigned Contract. If Purchaser elects for a Previously Unknown Contract to be an Assigned Contract in accordance with this Section, then to the extent not previously filed and served, Seller shall file and serve an assignment and assumption notice on the Contract counterparty to such Previously Unknown Contract (a “Supplemental Assignment Notice”) notifying such Contract counterparty of Seller’s intention to assume and assign to Purchaser such Previously Unknown Contract, including the proposed Cure Amount (if any). Such notice shall state that such Contract counterparty shall have fourteen (14) days to object to the assumption and assignment of the Contract to Purchaser (the “Supplemental Assignment Notice Objection Deadline”). Following expiration of the Supplemental Assignment Notice Objection Deadline and, if no objections are received, Seller shall submit a proposed order (in form and substance reasonably acceptable to Purchaser) to the Bankruptcy Court under certification of counsel authorizing the assumption and assignment of such Contract to Purchaser and, upon the entry of such an order, such Contract shall be deemed an Assigned Contract for all purposes under this Agreement and the Sale Order. If such Contract counterparty objects to the proposed assumption and assignment, the Contract at issue shall be deemed a Disputed Contract for all purposes under this Agreement.

(b) At any time prior to the earlier of confirmation of a plan in the Chapter 11 Cases or entry of an order dismissing the Chapter 11 Cases, Purchaser may elect to take an assignment of any Excluded Contract that has not yet been assumed and assigned pursuant to an order of the Bankruptcy Court (a “Previously Excluded Contract”) by sending a written notice to Seller (email being sufficient) of such election. If Purchaser elects for a Previously Excluded Contract to be an Assigned Contract in accordance with this Section, then to the extent not previously filed and served, Seller shall file and serve a Supplemental Assignment Notice on the Contract counterparty to such Previously Excluded Contract. Such Supplemental Assignment Notice Objection Deadline shall state that such Contract counterparty shall have fourteen (14) days to object to the assumption and assignment of the Contract to Purchaser. Following expiration of the Supplemental Assignment Notice Objection Deadline and if no objections are received, Seller shall submit a proposed order (in form and substance reasonably acceptable to Purchaser) to the Bankruptcy Court under certification of counsel authorizing the assumption and assignment of such Contract to Purchaser and, upon the entry of such an order, such Contract shall be deemed an Assigned Contract for all purposes under this Agreement and the Sale Order and, subject to Section 7.15 with respect to Cross-Over Contracts, the Purchaser shall be responsible for satisfying or paying any Cure Amounts or other Liabilities with respect to such Contract, whether or not such Cure Amounts or other Liabilities exceed the Purchaser Cure Amounts. For the avoidance of doubt, the Cross-Over Contracts are not Previously Excluded Contracts. If such Contract counterparty objects to the proposed assumption and assignment, the Contract at issue shall be deemed a Disputed Contract for all purposes under this Agreement.

34

(c) Seller and Purchaser agree that the Sale Order shall contain language approving the assumption and assignment procedures with respect to Disputed Contracts, Previously Unknown Contracts and Previously Excluded Contracts as set forth in Sections 5.3(b), 5.4 and 5.5 hereof.

Seller shall file the information required of a former owner, and Purchaser shall file the information required of a new owner, at each party’s own expense. Both Purchaser and the Seller also agree to use all commercially reasonable efforts to take any actions required by the Governmental Authority or other government/health agencies to effect the transfer of the Lonafarnib IND and other similar regulatory approval and authorization documents for jurisdictions outside of the United States from the Seller to Purchaser, and hereby further agree to cooperate with each other in order to effectuate the foregoing transfer of the Lonafarnib IND. The parties agree to use all commercially reasonable efforts to complete the filing of the transfer of the Lonafarnib IND and other similar regulatory approval and authorization documents for jurisdictions outside of the United States within ten (10) days from the Closing Date.

Purchaser and the Seller shall cooperate in good faith to prepare a joint press release to be issued on the Closing Date, the terms of which shall be mutually agreed upon by the parties.

6.7 Update of Schedules; Knowledge of Breach. From time to time prior to the Closing, the Seller may supplement or amend the Schedules with respect to any matter first arising after the Agreement Date that would have been required to be set forth or described in such Schedules. Any such supplemental or amended disclosure shall not be deemed to have cured any such breach of representation or warranty for purposes of determining whether or not the conditions set forth in Section 8.2(a) have been satisfied. From and after the Closing, references to the Schedules shall be references to the Schedules as supplemented, modified and/or updated. If, prior to the Closing, Purchaser shall have reason to believe that any breach of a representation or warranty of the Seller has occurred (other than through notice from the Seller), Purchaser shall promptly so notify the Seller, in reasonable detail. Nothing in this Agreement, including this Section 6.7, shall imply that the Seller is making any representation or warranty as of any date other than the Closing Date (other than representations and warranties that are expressly made as of an earlier date).

Seller will use reasonable efforts to not, and to ensure that its Affiliates do not (A) sell, assign, transfer, convey, deliver or otherwise divest its interests in any of the Existing Manufacturing Contracts to a Third Party in a manner that adversely affects, or would reasonably be expected to adversely affect, Purchaser’s rights or obligations under this Agreement or Purchaser’s ability to Commercialize any Lonafarnib Antiviral Products, (B) amend any of the Existing Manufacturing Contracts in a manner that adversely affects the rights granted to Purchaser under this Agreement or Purchaser’s ability to Commercialize any Lonafarnib Antiviral Products, or (C) undertake any action that would constitute a material breach of, and allow the Third Party that is a party to any Existing Manufacturing Contract to terminate, any Existing Manufacturing Contract, in each case, with respect to any Lonafarnib Antiviral Product.

44

(b) Seller will provide to Purchaser, within thirty (30) days following the end of a Calendar Quarter, an invoice for each preceding Calendar Quarter, which will include all fees, costs and expenses incurred by Seller in connection with, or other amounts due under, any Existing Manufacturing Contract to the extent such fees, costs, expenses or amounts relate to any Lonafarnib Antiviral Product or any Third Party services provided under such Existing Manufacturing Contracts to the extent related to any Lonafarnib Antiviral Product. Purchaser will pay each invoice no later than thirty (30) days after receipt. If Purchaser fails to pay the full amount of any invoice within such thirty (30) day period, then Seller may, upon reasonable notice to Purchaser, suspend its obligations hereunder to provide any and all services or other benefits under such Existing Manufacturing Contracts until such time as all invoices have been paid in full.

(c) As of each Existing Manufacturing Contract Date, except with respect to rights exercised by Seller on behalf of, or obligations delegated to, Purchaser pursuant to Section 7.11(a), or payments invoiced to Purchaser under Section 7.11(b) that have not been paid in full, the representations and warranties of Seller under Section 3.8 solely with respect to the Existing Manufacturing Contracts shall be true and correct in all respects as of applicable Existing Manufacturing Contract Date as though made at and as of such time.

7.12 Zokinvy Buyer Agreement. Following the Closing, Purchaser shall negotiate in good faith with the Zokinvy Buyer a Zokinvy Buyer Agreement which addresses the following matters: (a) the determination and allocation of Cross-Field Sales (as defined in the Merck License Agreement); (b) a safety data exchange agreement for the exchange of safety data relating to the Zokinvy Product and Lonafarnib Antiviral Products and responsibility for maintaining the Global Safety Databases; (c) a grant by Purchaser to the Zokinvy Buyer of a license to the Transferred Regulatory Information and Transferred Data to replace the license granted to Seller under Section 7.7, (d) a license and right of reference to, and right to access and receive copies of, the INDs and NDAs, including all modules thereof, related to the Zokinvy Product and all data related thereto directly from the Zokinvy Buyer, and letters of authorization in furtherance thereof; (e) a co-existence agreement for trademarks containing the word “Eiger”; and (f) supply by Purchaser to the Zokinvy Buyer of the Zokinvy Product under Purchaser’s rights under the Existing Manufacturing Contracts after the Existing Manufacturing Contract Transfer Date for such Existing Manufacturing Contract.

7.13 Joint Ownership of General Licensed Product Regulatory Information, General Licensed Product Data, and General Business Books and Records. As of the Closing Date, Seller shall assign, and hereby assigns, its entire right, title, and interest in and to all General Licensed Product Regulatory Information, General Licensed Product Data, and General Business Books and Records to Purchaser and the Zokinvy Buyer as equal joint owners, subject to and conditioned solely upon the agreement of Purchaser and the Zokinvy Buyer with respect to such joint ownership (the “Joint Ownership Agreement”). Such assignment shall be effective automatically and without further notice immediately and solely upon the effectiveness of the Joint Ownership Agreement. Following the Closing, Purchaser shall use good faith efforts to negotiate with the Zokinvy Buyer the Joint Ownership Agreement. Unless otherwise required under Applicable Law, including any Order or Final Order, Seller shall not grant any Third Party any license or right to, or sell, transfer, encumber, or distribute, any of its right, title, or interest in any General Licensed Product Regulatory Information, General Licensed Product Data, or General Business Books and Records without the prior written agreement of both Seller and the Zokinvy Buyer. Any breach of this Section 7.13 by Seller shall be deemed a material breach of this Agreement and entitle the Purchaser to seek specific performance.

45

7.14 Virology Collaborator Confirmation Letters. Within thirty (30) days after the Closing Date, the Seller and Purchaser shall use commercially reasonable efforts to obtain a Virology Collaborator Confirmation Letter from each Virology Collaborator.

7.15 Cross-Over Contracts.

(a) From the Agreement Date until the Plan Consummation Date, the Seller Group shall not, and shall cause its Affiliates not, to reject, amend, modify, sell, assign, license, transfer, convey, deliver or otherwise divest its interests in any of the agreements on Schedule 7.15 (the “Cross-Over Contracts”) in a manner that adversely affects, or would reasonably be expected to adversely affect, Purchaser’s rights or obligations under this Agreement, or Purchaser’s ability to Develop or Commercialize any Lonafarnib Antiviral Products.

(b) Except for those Cross-Over Contracts rejected, transferred, assigned or terminated by the Seller Group without violating Section 7.15(a), the Seller Group shall, upon Purchaser’s written request, transfer and assign, and hereby transfers and assigns, automatically and without further notice, to the Purchaser, each other Cross-Over Contract, effective on the date that is the earliest to occur of (a) the date that each and every Cross-Over Contract Benefited Party of such Cross-Over Contract obtains (i) a new agreement with the applicable counterparty of such Cross-Over Contract for substantially the same services as those then being provided to Seller by such counterparty under such Cross-Over Contract, or (ii) an agreement with a Third Party such that such services then being provided under such Cross-Over Contract to such Cross-Over Benefited Party are no longer needed by such Cross-Over Benefited Party, (b) the date Purchaser and all Cross-Over Contract Benefited Parties of such Cross-Over Contract agree to such transfer and assignment of such Cross-Over Contract, and (c) the date all Cross-Over Benefited Parties are no longer receiving any services under such Cross-Over Contract; and upon such transfer and assignment, such Cross-Over Contract shall be deemed an Assigned Contract for all purposes under this Agreement; the Purchaser shall be responsible for paying the associated Purchaser Cure Amount (if any) with respect to such Cross-Over Contract; and (if applicable) Seller shall be responsible for paying all related Seller Cure Amounts.

(c) Notwithstanding the foregoing Sections 7.15(a) and 7.15(c), (x) the IQVIA Contracts shall be Assigned Contracts upon the occurrence of the Satisfactory IQVIA Cure Resolution, and (y) the Cross-Over Contracts that are not IQVIA Contracts (the “Other Cross-Over Contracts”) shall be Assigned Contracts upon the occurrence of the Satisfactory Other Cure Resolution, provided that if the Satisfactory IQVIA Cure Resolution does not occur by the Plan Consummation Date, the IQVIA Contract shall be Excluded Contracts, and if the Satisfactory Other Cure Resolution does not occur by the Plan Consummation Date, the Other Cross-Over Contracts shall be Excluded Contracts. “Satisfactory IQVIA Cure Resolution” means a resolution of the cure objection with respect to the IQVIA Contracts that provides for a Cure Amount of no greater than $2,000,000 or that is otherwise acceptable to Purchaser in its sole discretion. “Satisfactory Other Cure Resolution” means a resolution of the cure objections with respect to the Other Cross-Over Contracts that provides for a Cure Amount either (i) in the aggregate with the Cure Amount of the Satisfactory IQVIA Cure Resolution, of no greater than $2,000,000, or (ii) if in excess of (i), that is otherwise acceptable to Purchaser in its sole discretion. In the event that the a Cross-Over Contract becomes an Excluded Contract, Purchaser agrees to use commercially reasonable efforts to preserve the Transferred Data, including the Global Safety Databases, and fully transfer and transition the Transferred Data and Transferred Regulatory Information to Purchaser, and shall not instruct the counterparties to the IQVIA Contracts to delete or remove the Transferred Data from the Global Safety Databases.

46

(d) For the avoidance of doubt, after the Closing Date, when any Cross-Over Contract becomes an Assumed Contract, the Seller and Purchaser shall each promptly pay or cause to be paid all Purchaser Cure Amounts and Seller Cure Amounts (if any) for such Assumed Contract.

7.16 Confirmation Letters. Within seven (7) Business Days after Purchaser’s written request provided to Seller after the Closing, Seller and its Affiliates shall provide a letter of confirmation to Purchaser for delivery by Purchaser to any Person that possesses or otherwise holds any Transferred Assets that confirms that Purchaser acquired and is the exclusive owner of the relevant Transferred Assets held by such Person in a form reasonably acceptable to Purchaser. Purchaser will have the right to provide any such letter of confirmation to any Person.

9.3 Termination Fee and Expense Reimbursement.

(a) Subject to limitations set forth in the Bid Procedures Order, in consideration of Purchaser having expended considerable time and expense in connection with this Agreement and the negotiation thereof, and the identification and quantification of assets to be included in the Transferred Assets, and to compensate Purchaser as a stalking-horse bidder, the Seller shall pay in cash to Purchaser, by wire transfer of immediately available funds to the account specified by Purchaser to the Seller in writing, an amount equal to the Termination Fee in the event that this Agreement is terminated pursuant to any of Sections 9.1(b)-(f) or 9.1(h)-(i) in which case the Termination Fee shall be due and payable simultaneously with any termination of this Agreement; provided that Purchaser shall not be entitled to the fee described in this Section 9.3(a) to the extent Purchaser is in material breach of this Agreement at the time this Agreement is terminated pursuant to Sections 9.1(b)-(f) or 9.1(h)-(i) if Seller has provided notice of such material breach to Purchaser and such material breach has remained uncured for more than five (5) Business Days after Purchaser’s receipt of such notice. The Seller’s obligation to pay the Termination Fee pursuant to this Section 9.3(a) shall survive termination of this Agreement and shall constitute an administrative expense of the Seller under section 364(c)(1) of the Bankruptcy Code with priority over any and all administrative expenses of the kind, including those specified in section 503(b) or 507(b) of the Bankruptcy Code.

(b) Subject to limitations set forth in the Bid Procedures Order, in consideration of Purchaser having expended considerable time and expense in connection with this Agreement and the negotiation thereof, and the identification and quantification of assets to be included in the Transferred Assets, if this Agreement is terminated in accordance with the terms set forth in any of Sections 9.1(b)-(f) or 9.1(h)-(i), then the Seller shall pay to Purchaser in cash not later than two (2) Business Days following receipt of documentation supporting the request for reimbursement of costs, fees and expenses, the Expense Reimbursement, in an amount not to exceed $224,000, by wire transfer of immediately available funds to an account specified by Purchaser to the Seller in writing; provided that Purchaser shall not be entitled to the fee described in this Section 9.3(b) to the extent Purchaser is in material breach of this Agreement at the time this Agreement is terminated pursuant to Sections 9.1(b)-(f) or 9.1(h)-(i) if Seller has provided notice of such material breach to Purchaser and such material breach has remained uncured for more than five (5) Business Days after Purchaser’s receipt of such notice. The Seller’s obligation to pay the Expense Reimbursement pursuant to this Section 9.3(b) shall survive termination of this Agreement and shall constitute an administrative expense of Seller under section 364(c)(1) of the Bankruptcy Code with priority over any and all administrative expenses of the kind, including those specified in section 503(b) or 507(b) of the Bankruptcy Code.

50

(c) The Seller agrees and acknowledges that Purchaser’s due diligence, efforts, negotiation, and execution of this Agreement have involved substantial investment of management time and have required significant commitment of financial, legal, and other resources by Purchaser, and that such due diligence, efforts, negotiation, and execution have provided value to the Seller and, in the Seller’s reasonable business judgment, is necessary for the preservation of the value of the Seller’s estate. The Seller further agrees and acknowledges that the Termination Fee and the Expense Reimbursement are not a penalty, but rather represent liquidated damages that are reasonable in relation to Purchaser’s efforts, Purchaser’s lost opportunities from pursuing the Transactions, and the magnitude of the Transactions. The provision of the Termination Fee and the Expense Reimbursement is an integral part of this Agreement, without which Purchaser would not have entered into this Agreement.

ARTICLE 10.

GENERAL PROVISIONS

10.1 Survival of Representations, Warranties and Covenants. All covenants and agreements contained in this Agreement that by their term are to be performed in whole or in part, or which prohibit actions, subsequent to Closing shall, solely to the extent such covenants and agreements are to be performed, or prohibit actions, subsequent to Closing, survive the Closing in accordance with their terms until fully performed or satisfied. All other covenants and agreements contained herein, and all representations and warranties contained herein or in any certificated deliveries hereunder shall not survive Closing and shall therefor terminate, including any Action for damages in respect of any breach or inaccuracy thereof. Notwithstanding the foregoing, the provisions of Section 2.9(c), Section 6.2, Section 9.2, this ARTICLE 10 and the Confidentiality Agreement shall survive the Closing. For the avoidance of doubt, nothing in this Section 10.1 shall affect the survival of the covenants or representations or warranties of Seller under the Sublicense Agreement or its related agreements.

10.2 Entire Agreement. This Agreement, including the Exhibits and Schedules hereto, the Confidentiality Agreement and the Related Documents, contain the entire understanding of the parties hereto with respect to the subject matter contained herein and therein. This Agreement supersedes all prior and contemporaneous agreements, arrangements, contracts, discussions, negotiations, undertakings and understandings (including any letters of intent or term sheets), whether written or oral, among the parties with respect to such subject matter (other than, for the avoidance of doubt, the Confidentiality Agreement and the Related Documents) or any prior course of dealings. The parties hereto have voluntarily agreed to define their rights, Liabilities and obligations respecting the Transactions exclusively in contract pursuant to the express terms and conditions of this Agreement, the Confidentiality Agreement and the Related Documents, and the parties hereto expressly disclaim that they are owed any duties or entitled to any remedies not expressly set forth in this Agreement, the Confidentiality Agreement and the Related Documents. Furthermore, the parties each hereby acknowledge that this Agreement, the Confidentiality Agreement and the Related Documents embody the justifiable expectations of sophisticated parties derived from arm’s-length negotiations, and all parties to this Agreement, the Confidentiality Agreement and the Related Documents specifically acknowledge that no party has any special relationship with another party that would justify any expectation beyond that of an ordinary purchaser and an ordinary seller in an arm’s-length transaction. The sole and exclusive remedies for any Related Claims shall be those remedies available at law or in equity for breach of contract only (as such contractual remedies have been further limited or excluded pursuant to the express terms of this Agreement); and the parties hereby agree that neither party hereto shall have any remedies or cause of action (whether in contract or in tort or otherwise) of any statements, communications, disclosures, failures to disclose, representations or warranties not set forth in this Agreement.

10.3 Amendment; No Waiver. This Agreement and the Related Documents may be amended, supplemented or changed, and any provision hereof or thereof can be waived, only by a written instrument making specific reference to this Agreement (and, if applicable, the Related Documents) executed by the party against whom enforcement of any such amendment, supplement, modification or waiver is sought.

51

The waiver by any party of a breach of any provision of this Agreement or the Related Documents shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any party to exercise, and no delay in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall a single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

10.4 Severability; Specific Versus General Provisions. Whenever possible, each provision of this Agreement and the Related Documents shall be interpreted in such manner as to be effective and valid under Applicable Law, but if any term or other provision of this Agreement or the Related Documents is invalid, illegal, or incapable of being enforced by any Applicable Law or public policy, all other terms or provisions of this Agreement and the Related Documents shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, in whole or in part, such term or provision is hereby deemed modified to give effect to the original written intent of the parties to the greatest extent consistent with being valid and enforceable under Applicable Law. No party hereto shall assert, and each party shall cause its respective Affiliates or related parties not to assert, that this Agreement or any part hereof is invalid, illegal or unenforceable. Notwithstanding anything to the contrary, to the extent that a representation, warranty, covenant or agreement of the Seller contained in this Agreement or the Schedules (each, a “Provision”) addresses a particular issue with specificity (a “Specific Provision”), and no breach by the Seller exists under such Specific Provision, the Seller shall not be deemed to be in breach of any other Provision (with respect to such issue) that addresses such issue with less specificity than the Specific Provision, and if such Specific Provision is qualified or limited by the Seller’s Knowledge, or in any other manner, no other Provision shall supersede or limit such qualification in any manner.

10.5 Expenses and Obligations. Except as otherwise provided in this Agreement, all costs and expenses incurred by the parties hereto in connection with the Transactions, including the costs, expenses and disbursements of counsel and accountants, shall be borne solely and entirely by the party that has incurred such expenses; provided, however, that Purchaser shall pay, or promptly reimburse the Seller for, any filing fees which relate to any required governmental filing or notification and Purchaser shall pay any Transfer Taxes.

10.6 Notices. All notices, consents, waivers, and other communications under this Agreement or the Related Documents shall be in writing and will be deemed to have been duly given (a) if personally delivered, on the date of delivery, (b) if delivered by express courier service of national standing for next day delivery (with charges prepaid), on the Business Day following the date of delivery to such courier service, (c) if delivered by electronic mail (unless the sender receives an automated message that the email has not been delivered) on the date of transmission if on a Business Day before 5:00 p.m. local time of the business address of the recipient party (otherwise on the next succeeding Business Day) and (d) if deposited in the United States mail, first-class postage prepaid, on the date of delivery, in each case to the appropriate addresses or email addresses set forth below (or to such other addresses as a party may designate by notice to the other parties in accordance with this Section 10.6):

(a) Without limiting any party’s right to appeal any Order of the Bankruptcy Court, (i) the Bankruptcy Court shall retain exclusive jurisdiction to interpret and/or enforce the terms of this Agreement and to decide any claims or disputes which may arise or result from, or be connected with, this Agreement, any Related Document, any breach or default hereunder or thereunder, or the Transactions, and (ii) any and all proceedings related to the foregoing shall be filed and maintained only in the Bankruptcy Court, and the parties hereby consent to and submit to the jurisdiction and venue of the Bankruptcy Court and shall receive notices at such locations as indicated in Section 10.6; provided, however, that if the Bankruptcy Cases have closed, the parties agree to irrevocably submit to the exclusive jurisdiction of the United States District Court for the Northern District of Texas over all Related Claims, and each party hereto hereby irrevocably agrees that all Related Claims may be heard and determined in such courts. The parties hereto hereby irrevocably and unconditionally waive, to the fullest extent permitted by Applicable Law, any objection which they may now or hereafter have to the laying of venue of any such Related Claim brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Law.

53

(b) Each of the parties hereto hereby consents to process being served by any party to this Agreement in any Related Claim by the delivery of a copy thereof in accordance with the provisions of Section 10.6 (other than by email) along with a notification that service of process is being served in conformance with this Section 10.9(b). Nothing in this Agreement will affect the right of any party to serve process in any other manner permitted by Applicable Law.

10.10 Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT, THE RELATED DOCUMENTS OR ANY RELATED CLAIMS IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY EXPRESSLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING OR RELATED CLAIM BROUGHT BY OR AGAINST IT, DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE RELATED DOCUMENTS OR ANY RELATED CLAIMS.

10.11 Rights Cumulative. All rights and remedies of each of the parties under this Agreement and the Related Documents will be cumulative, and the exercise of one or more rights or remedies will not preclude the exercise of any other right or remedy available under this Agreement, the Related Documents or Applicable Law.

10.12 Assignment. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors by operation of law and permitted assigns of the parties hereto. No assignment of this Agreement or any of the rights, interests or obligations under this Agreement may be made by any party hereto at any time, whether or not by operation of law, without the prior written consent of the Seller and Purchaser, and any attempted assignment without the required consent shall be void; provided, however, that (a) Purchaser may assign (i) any of its rights or delegate any of its duties under this Agreement to any of its Affiliates, and (ii) its rights, but not its duties, under this Agreement to any of its financing sources and (b), the Seller may assign any of its rights or delegate any of its duties under this Agreement (i) to any of its Affiliates, (ii) to any creditor or group of creditors pursuant to an order of the Bankruptcy Court entered in the Bankruptcy Cases, including Seller’s rights to payment hereunder and rights and ability to enforce the terms of this Agreement and (iii) for collateral security purposes to any lender of the Seller or its Affiliates; provided, further, however, that, in each case, such assignment shall not release Purchaser from its obligations under this Agreement and the Seller shall have no obligation to pursue remedies against any assignee of Purchaser before proceeding against Purchaser for any breach of Purchaser’s obligations hereunder.

10.13 Specific Enforcement; Remedies. The parties hereto agree that irreparable damage (for which monetary relief, even if available, would not be an adequate remedy) would occur in the event that any of the provisions of this Agreement were not performed by the parties hereto in accordance with their specific terms or were otherwise breached. It is accordingly agreed that (i) Purchaser, on the one hand, and the Seller, on the other hand, shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction without proof of damages or otherwise and that this shall include the right of the Seller to cause Purchaser to fully perform the terms of this Agreement to the fullest extent permissible pursuant to this Agreement and Applicable Laws and to thereafter cause this Agreement and the Transactions to be consummated on the terms and subject to the conditions thereto set forth in this Agreement, and (ii) the right of specific performance and other equitable relief is an integral part of the Transactions and without that right, neither the Seller nor Purchaser would have entered into this Agreement. Remedies shall be cumulative and not exclusive and shall be in addition to any other remedies which any party may have under this Agreement. Each of the parties hereto hereby (A) waives any defenses in any action for specific performance, including the defense that a remedy at law would be adequate, (B) waives any requirement under any Applicable Law to post a bond or other security as a prerequisite to obtaining equitable relief and (C) agrees not to assert that a remedy of specific performance or other equitable relief is unenforceable, invalid, contrary to law or

54

inequitable for any reason, and not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. Notwithstanding anything to the contrary, in no event shall this Section 10.13 be used, alone or together with any other provision of this Agreement, to require the Seller to remedy any breach of any representation or warranty of the Seller.

10.14 Third-Party Beneficiaries. Except as set forth in ARTICLE 2 (with respect to the Seller), Section 10.15 (with respect to the Nonparty Affiliates), Section 10.16 (with respect to the released parties identified therein), Section 10.17 (with respect to the Sellers’ Group Members) and the next sentence, nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto any rights or remedies of any nature whatsoever under or by reason of this Agreement. From and after the Closing, all of the Persons identified as third-party beneficiaries in the first sentence of this Section 10.14 shall be entitled to enforce such provisions and to avail themselves of the benefits of any remedy for any breach of such provisions, all to the same extent as if such Persons were parties to this Agreement. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with this Agreement without notice or Liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any party hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the Agreement Date or as of any other date.

10.15 No Personal Liability of Directors, Officers and Owners. All Related Claims may be made only against (and are those solely of) the entities that are expressly identified as parties in the preamble to this Agreement (the “Contracting Parties”). No Person who is not a Contracting Party, including any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, representative or assignee of, or any financial advisor or lender to, any Contracting Party, or any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, representative or assignee of, or any financial advisor or lender to, any of the foregoing (collectively, “Nonparty Affiliates”), shall have any Liability pursuant to any Related Claim; and, to the maximum extent permitted by Applicable Law, each Contracting Party hereby waives and releases all such Liabilities, claims, causes of action, and obligations against any such Nonparty Affiliates. Without limiting the foregoing, to the maximum extent permitted by Applicable Law, (a) each Contracting Party hereby waives and releases any and all rights, claims, demands, or causes of action that may otherwise be available at Applicable Law or in equity, or granted by statute, to avoid or disregard the entity form of a Contracting Party or otherwise impose Liability of a Contracting Party on any Nonparty Affiliate, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise; and (b) each Contracting Party disclaims any reliance upon any Nonparty Affiliates with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement or the Related Documents.

10.16 General Release.

(a) Effective as of the Closing, the Seller, on behalf of itself, its Affiliates and each of their respective successors and assigns (each of the foregoing, a “Seller Releasing Party”), hereby fully, irrevocably and unconditionally releases and forever discharges Purchaser and its respective past and present directors, managers, officers, employees, agents, stockholders, members, representatives and Affiliates from and against, and covenants that it will not (directly or indirectly) assert any claim or proceeding of any kind before any Governmental Authority based upon, any and all claims, Actions, causes of action, suits, rights, agreements, Liabilities and demands whatsoever and all consequences thereof, known or unknown, actual or potential, suspected or unsuspected, fixed or contingent, both in law and in equity, whether existing as of the Closing or arising thereafter, that a Seller Releasing Party

55

has or may have, now or in the future, arising out of, relating to, or resulting from any act or omission, error, negligence, breach of contract, tort, violation of law, matter or cause whatsoever from the beginning of time to the Closing Date. The foregoing sentence shall not be deemed to be a release or waiver by a Seller Releasing Party of any Action it may have under this Agreement or any of the other Related Documents.

(b) Effective as of the Closing, Purchaser, on behalf of itself, its Affiliates and each of their respective successors and assigns (each of the foregoing, a “Purchaser Releasing Party”), hereby fully, irrevocably and unconditionally releases and forever discharges the Seller, the Seller’s Affiliates and its and their respective past and present directors, managers, officers, agents, stockholders, members, representatives and Affiliates from and against, and covenants that it will not (directly or indirectly) assert any claim or proceeding of any kind before any Governmental Authority based upon, all claims, Actions, causes of action, suits, rights, agreements, Liabilities and demands whatsoever and all consequences thereof, known or unknown, actual or potential, suspected or unsuspected, fixed or contingent, both in law and in equity, whether existing as of the Closing or arising thereafter, that a Purchaser Releasing Party has or may have, now or in the future, arising out of, relating to, or resulting from any act or omission, error, negligence, breach of contract, tort, violation of law, matter or cause whatsoever from the beginning of time to the Closing Date. The foregoing sentence shall not be deemed to be a release or waiver by a Purchaser Releasing Party of any Action it may have under this Agreement or any of the other Related Documents.

10.17 Legal Representation. Purchaser and the Seller acknowledge and agree that the Law Firm has represented the Seller Group in connection with the negotiation, preparation, execution, delivery and performance of this Agreement and the Related Documents and the consummation of the Transactions, and that the Seller, its Affiliates and its partners, officers, directors and representatives (the “Seller Group Members”) have a reasonable expectation that the Law Firm will represent them in connection with any Action involving any Seller Group Member, on the one hand, and Purchaser or any of its Affiliates and representatives (the “Purchaser Group Members”), on the other hand, arising under this Agreement, the Related Documents or the Transactions. Purchaser hereby, on behalf of itself and the other Purchaser Group Members, irrevocably: (a) acknowledges and agrees that any attorney-client privilege, solicitor-client privilege, work product or other attorney-client or solicitor-client confidential information (“Attorney-Client Information”) arising from communications prior to the Closing between the Seller (including any one or more officers, directors or stockholders of such Seller), on the one hand, and the Law Firm, on the other hand, is not included in the property, rights, privileges, powers, franchises and other interests that are possessed by or vested in the Business or the Transferred Assets, that any such Attorney-Client Information shall be deemed property of, and controlled solely by, such Seller for the benefit and on behalf of the Seller Group Members and, upon request, convey and transfer any Attorney-Client Information to the Seller; (b) acknowledge and agree that the Seller Group Members shall have the right to retain, or cause the Law Firm to retain, any such documentation or information in the possession of the Law Firm or such Seller Group Members at the Closing; (c) agree not to access, retain or use any documentation or information constituting Attorney-Client Information and that no Purchaser Group Member shall have any right to waive any attorney-client privilege or other right to confidentiality with respect to such Attorney-Client Information; (d) disclaim the right to assert a waiver by any Seller Group Member with regard to the attorney-client privilege, solicitor-client privilege or other right to confidentiality with respect to such Attorney-Client Information solely due to the fact that such documentation or information is physically in the possession of Purchaser after the Closing; (e) consent to the Law Firm’s representation after the Closing of any Seller Group Member in any Action that may relate to a Purchaser Group Member or the Transactions and consent to and waive any conflict of interest arising therefrom without the need for any future waiver or consent; and (f) consent to the disclosure by the Law Firm to any Seller Group Member of any documentation or information obtained by the Law Firm during the course of its representation of Seller or any Affiliate prior to the Closing, whether related to this Agreement, the Related Documents, the Transactions or otherwise, whether or not such disclosure is made prior to or after the Closing and whether

56

or not the documentation or information disclosed is subject to any attorney-client privilege, solicitor-client privilege or confidentiality obligation to any Seller Group Member, any Affiliate of the Seller or any other Person. In the event that any Action arises after the Closing between any Purchaser Group Member and a Person other than a Seller Group Member, such Purchaser Group Member shall not disclose any documentation or information that is subject to an attorney-client privilege or other rights of confidentiality referenced in this Section 10.17 without the prior written consent of the applicable Seller; provided, however, that if such Purchaser Group Member is required by judicial order or other legal process to make such disclosure, such Purchaser Group Member shall promptly notify the applicable Seller in writing of such requirement (without making disclosure) and shall provide such Seller with such cooperation and assistance as shall be necessary to enable such Seller to prevent disclosure by reason of such attorney-client privilege, solicitor-client privilege or other rights of confidentiality. This Section 10.17 is for the benefit of the Seller Group Members and such Persons are intended third-party beneficiaries of this Section 10.17.
