2.5 Non-Assignment of Assets. Notwithstanding any other provision of this Agreement to the contrary, this Agreement shall not constitute an agreement to assign or transfer and shall not affect the assignment or transfer of any Purchased Asset if (i) an attempted assignment or transfer thereof, without the approval, authorization or consent of, or granting or issuance of any license or permit by, any third party thereto or a Governmental Body (each such action, a “Necessary Consent”), would constitute a breach, default or violation thereof or of any Law or Order or in any way adversely affect

-30-

the rights of Purchaser thereunder and (ii) the Bankruptcy Court has not entered an Order providing that such Necessary Consent is not required. In such event, such assignment or transfer is subject to such Necessary Consent being obtained, and the Sellers shall use their commercially reasonable efforts to obtain the Necessary Consents with respect to any such Purchased Asset or any claim or right or any benefit arising thereunder for the assignment or transfer thereof to Purchaser as Purchaser may reasonably request. For the avoidance of doubt, any asset that would be a Purchased Asset but is not assigned in accordance with this Section 2.5 shall not be considered a “Purchased Asset” for purposes hereof unless and until such asset is assigned to Purchaser following the Closing Date upon receipt of the Necessary Consent and Bankruptcy Court approval. If such Necessary Consent is not obtained, or if an attempted assignment or transfer thereof would be ineffective or would adversely affect the rights of Purchaser to such Purchased Asset following the Closing, the Sellers shall cooperate with Purchaser in any reasonable arrangement to provide for Purchaser to obtain the benefits and assume the obligations thereunder in accordance with this Agreement, including subcontracting, sub‑licensing, or sub-leasing to Purchaser, or under which the applicable Seller would enforce for the benefit of Purchaser all of its rights thereunder.

2.6 Contract Designation; Cure Costs.

(a) Section 2.6 of the Seller Disclosure Schedule sets forth each Executory Contract and the Sellers’ good faith estimate of the amount of the Cure Costs payable in respect of each such Executory Contract (and if no Cure Cost is estimated to be payable in respect of any particular Executory Contract, the amount of such Cure Cost designated for such Contract shall be “$0.00”). On the date that is no later than fourteen (14) days prior to the Sale Hearing, the Sellers shall deliver a written notice in a form reasonably acceptable to Purchaser of the proposed assignments of the Executory Contracts and the proposed Cure Costs for each Executory Contract to all non-debtor parties of Executory Contracts, which notice shall notify each non-debtor party of (i) the proposed Cure Cost for such Executory Contract and (ii) an objection deadline for such non-debtor party to object to the proposed Cure Cost. Subject to the limitations set forth in the DIP Credit Agreement, to the extent that any objections are received from such non-debtor parties in response to such notice, the Sellers shall use their commercially reasonable efforts to resolve such disputes with the applicable non-debtor party. Notwithstanding anything herein to the contrary, at any time prior to the date that is five (5) days after the judicial or non-judicial (i.e., by agreement) resolution of any dispute with a non-debtor party to a Executory Contract relating to Cure Cost or adequate assurance with respect to any particular Executory Contract as to which a cure objection has been timely filed, Purchaser shall be entitled, in its sole discretion, to add any Executory Contract to the schedule of Excluded Contracts on Section 1.1(d) of the Seller Disclosure Schedule and remove such Executory Contract from the schedule of Executory Contracts on Section 1.1(e) of the Seller Disclosure Schedule by providing written notice thereof to the Sellers, and any Executory Contract so added shall be deemed to be an “Excluded Contract” and shall not be deemed to be a “Purchased Contract” or an “Executory Contract” for all purposes hereunder without further action by the parties.

-31-

(b) The Sellers shall give written notice to Purchaser prior to the submission by any Seller Entity of any motion in its Bankruptcy Case to assume or reject any Contract related to the Business together with a copy of the proposed Order authorizing the assumption or rejection of such Contract; provided, that in no event shall any Seller Entity seek to reject, or reject, any Contract related to the Business prior to the Closing Date unless prior written approval has been obtained from Purchaser; and provided, further, that the Sellers shall not seek to reject, or reject, any Contract that is an Executory Contract.

(c) To the extent that any Executory Contract requires the payment of Cure Costs in order to be assigned to Purchaser and assumed pursuant to section 363 and 365 of the Bankruptcy Code, the Cure Costs related to such Executory Contract shall be paid by the Purchaser. Purchaser shall not be required to make any payment of Cure Costs for, or otherwise have any Liabilities with respect to, any Contract that is not an Executory Contract. Purchaser shall provide adequate assurance of future performance on its behalf and on behalf of its designees as required under the Bankruptcy Code, including section 365(f)(2)(B) thereof.

(d) Notwithstanding anything to the contrary herein, Purchaser may from time to time prior to the Closing in its sole discretion designate any Purchased Contract as an Excluded Contract by providing written notice thereof to the Sellers. Such Contract (i) shall be added to the schedule of Excluded Contracts on Section 1.1(d) of the Seller Disclosure Schedule and to the extent applicable, removed from the schedule of Executory Contracts on Section 1.1(e) of the Seller Disclosure Schedule, and (ii) shall be deemed to be an “Excluded Contract” and shall not be deemed to be a “Purchased Contract,” or an “Executory Contract” for all purposes hereunder, in each case, without further action by the parties.

2.7 Further Conveyances and Assumptions. From time to time following the Closing, the Sellers and Purchaser shall, and shall cause their respective Affiliates to, execute, acknowledge and deliver all such further conveyances, notices, assumptions, assignments, releases and other instruments, and shall take such further actions, as may be reasonably necessary or appropriate to assure fully to Purchaser and its respective successors or assigns, all of the properties, rights, titles, interests, estates, remedies, powers and privileges intended to be conveyed to Purchaser under this Agreement and to assure fully to each Seller and its Affiliates and their successors and assigns, the assumption of the liabilities and obligations intended to be assumed by Purchaser under this Agreement, and to otherwise make effective the transactions contemplated hereby; provided, that nothing in this Section 2.7 shall require Purchaser or any of its Affiliates to assume any Liabilities other than the Assumed Liabilities.

2.8 Assignment to Affiliates of Purchaser. Prior to the Closing, Purchaser shall have the right to assign its rights to receive all or any part of the Purchased Assets and its obligations to assume all or any part of the Assumed Liabilities, in each

-32-

case to one or more Affiliates of Purchaser by providing written notice to the Company and each such designated Affiliate shall be deemed to be a Purchaser for all purposes hereunder and under the Ancillary Agreements, except that no such assignment shall relieve Purchaser of any of its obligations hereunder.

In the event that the entry of the Bidding Procedures Order or the Sale Order is appealed or a stay pending appeal is sought, the Sellers shall oppose the appeal or the stay pending appeal and seek the dismissal of any appeal (including a petition for certiorari, motion for rehearing, reargument, reconsideration or revocation). Notwithstanding the foregoing, any resulting changes to this Agreement or any Ancillary Agreement or resulting changes to the Bidding Procedure Order and the Sale Order shall be subject to Purchaser’s, the Trustee’s and the Required Lenders’ approval in their sole discretion.

to defend any Legal Proceedings which would prevent the condition to Closing described in Section 9.4(a) from being satisfied, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Body with respect thereto vacated or reversed, and shall cooperate with each other in connection with the foregoing.

(b) If after the Closing (i) Purchaser holds any Excluded Assets or Excluded Liabilities or (ii) any Seller Entity holds any Purchased Assets or Assumed Liabilities (including any proceeds, accounts receivable, notes receivable, income, revenues, monies and other items attributable to the Purchased Assets), Purchaser or the applicable Seller Entity, shall promptly transfer (or cause to be transferred) such assets or assume (or cause to be assumed) such Liabilities to or from (as the case may be) the other party.

(a) The Sellers shall maintain until Closing all existing insurance policies relating to the Business or the Purchased Assets (the “Seller Policies”), at their sole cost and expense. If, between the date hereof and the Closing, any of the Purchased Assets shall be damaged or destroyed by fire, theft, vandalism or other casualty event, or become subject to any condemnation or eminent domain proceeding, the Sellers

-71-

shall promptly notify Purchaser in writing of such fact and Purchaser shall have the option to (a) acquire such Purchased Assets on an “as is” basis and take an assignment from the Sellers of any and all insurance proceeds payable to the Sellers in respect of such event, (b) elect to exclude such Purchased Asset from this Agreement, or (c) in the event such event would have a Seller Material Adverse Effect, terminate this Agreement and the transactions contemplated hereby.

(b) Purchaser shall replace signage at Wells to the extent required by applicable Law.

8.10 Confidentiality.

The Sellers acknowledge and agree that from and after the Closing, all non-public information relating to the Business, including the Purchased Assets and the Assumed Liabilities, shall be valuable and proprietary to Purchaser and its Affiliates. The Sellers agree that, from and after the Closing, no Seller shall, and the Sellers shall cause the other Seller Entities not to, disclose to any Person any information relating to Purchaser and its Affiliates, or the Business, including the Purchased Assets and the Assumed Liabilities, except as required by Law or as otherwise becomes available in the public domain other than through any action by any Seller in violation of its obligations under this Section 8.10; provided, that the Sellers shall use their commercially reasonable efforts, and shall cause the other Seller Entities to use their commercially reasonable efforts, consistent with such applicable Law requirement to consult with Purchaser with respect to the text thereof to the extent practicable. The Sellers acknowledge and agree that the remedies at law for any breach or threatened

-72-

breach of this Section 8.10 by any Seller Entity are inadequate to protect Purchaser and its respective Affiliates and that the damages resulting from any such breach are not readily susceptible to being measured in monetary terms. Accordingly, without prejudice to any other rights or remedies otherwise available to Purchaser or its respective Affiliates, each party acknowledges and agrees that upon any breach or threatened breach by a Seller Entity of the terms and conditions of this Section 8.10, Purchaser and its respective Affiliates, as applicable shall be entitled to seek immediate injunctive relief and to an order restraining any threatened or future breach from any court of competent jurisdiction without proof of actual damages or posting of any bond in connection with any such remedy. The provisions of this Section 8.10 shall survive the Closing.

8.11 Employee Matters.

(a) The Sellers shall promptly update the list of Employees made available to Purchaser pursuant to Section 5.14(a) and Section 5.14(a) of the Seller Disclosure Schedule to reflect any and all employment or service hirings or terminations occurring prior to the Closing Date, with the final such update to occur no later than five (5) Business Days prior to the Closing Date (it being understood that the Sellers will inform Purchaser in writing of the termination of employment or services of an Employee or Service Provider following the date hereof).

All Offered Employees who (A) accept the offer of employment from Purchaser or one of its Affiliates and (B) commence employment with Purchaser or one of its Affiliates as of immediately following the Closing shall be referred to herein as the “Transferred Employees.” Unless a written acceptance of an offer of employment is required by applicable Law, an Offered Employee who is actively at work with Purchaser or one of its Affiliates as of the Closing Date and continues employment shall be deemed to have accepted the offer of employment from Purchaser or one of its Affiliates, unless such Offered Employee specifically declines such offer of employment.

(c) The employment of each Transferred Employee with Purchaser or one of its Affiliates shall commence immediately upon the Closing and shall be deemed, for all purposes, consistent with applicable Law and except as otherwise expressly provided herein, to have occurred with no interruption or break in service and no termination of employment; provided, however, that any Inactive Employee shall not

-73-

be considered a Transferred Employee unless and until such Inactive Employee returns to active status pursuant to the following sentence, and notwithstanding anything herein to the contrary, Purchaser and its Affiliates shall only be responsible for Liabilities relating to the Inactive Employee from and after the date such Inactive Employee becomes a Transferred Employee. The employment of any Inactive Employee with Purchaser or one of its Affiliates, as applicable, shall be effective upon his or her return to active work, provided that the Inactive Employee reports to work with Purchaser or one of its Affiliates, as applicable, within fifteen (15) days after the end of any such approved leave and, to the extent permitted by applicable Law, in no event later than one hundred twenty (120) days following the Closing Date, and, as of such date, such Inactive Employee shall be a Transferred Employee. Each Transferred Employee shall be hired on an “at will” basis unless otherwise agreed by Purchaser.

(d) The Sellers shall terminate, or shall cause to be terminated, the employment of all Transferred Employees effective as of the Closing or, with respect to any Inactive Employee who becomes a Transferred Employee after the Closing Date in accordance with Section 8.11(c), upon their return to active work with Purchaser or one of its Affiliates, as applicable. Subject to, and effective as of, the Closing, the Sellers hereby waive and release each of the Transferred Employees from any and all contractual, common law or other restrictions enforceable by the Sellers and their respective Affiliates on the employment, activities or other conduct of such individuals after their termination of employment with the Sellers except with respect to obligations related to confidentiality and trade secrets. Prior to the Closing Date, and to the extent necessary to implement this sentence, the Sellers shall cause to be taken all actions as may be reasonably required to amend any Employee Benefit Plan and take or cause to be taken all other action as may be reasonably required to provide that severance or separation payments shall not be payable to any Transferred Employee on account of such employee’s termination of employment with the Sellers and its Affiliates.

(f) Effective as of the Closing, Purchaser or one of its Affiliates shall assume sponsorship of each of the Employee Benefit Plans listed on Section 8.11(f) of the Seller Disclosure Schedule (the “Transferred Benefit Plans”), and any trusts,

-74-

insurance policies or third-party administrator contracts related to the Transferred Benefit Plans shall be assigned to Purchaser or one of its Affiliates effective as of the Closing.

(g) Purchaser shall be responsible for all workers’ compensation claims relating to any Transferred Employees if the incident or alleged incident giving rise to the claim occurred on or after the Closing Date. The Sellers shall be responsible for all workers’ compensation claims relating to any Transferred Employees if the incident or alleged incident giving rise to the claim occurred prior to the Closing Date.

(h) With respect to any accrued but unused vacation or paid time-off benefits (“Accrued PTO”) to which any Transferred Employee is entitled pursuant to the vacation policy or other arrangement applicable to such Transferred Employee immediately prior to the Closing as reflected in the list of Employees made available to Purchaser pursuant to Section 5.14(a), Purchaser shall, or shall cause its Affiliate to, either (A) allow such Transferred Employee to use such Accrued PTO or (B) to the extent permitted by applicable Law, pay or cause Seller to pay any or all of the value of such Accrued PTO to such Transferred Employee in cash.

(i) Nothing herein, express or implied, shall confer upon any other Persons (including any current or former employee of the Seller, Purchaser or any of their respective Affiliates) any rights or remedies hereunder, including any right to employment or continued employment for any specified period or continued participation in any Employee Benefit Plan or other benefit plan, or any nature or kind whatsoever under or by reason of this Agreement. Nothing herein restricts or precludes the right of Purchaser to terminate the employment of any Transferred Employee.

With respect to any Periodic Non-Income Taxes that are assessed on, or in respect of, the Purchased Assets and attributable to any period that ends on or prior to the Closing Date, if Purchaser pays such Periodic Non-Income Taxes, as promptly as practicable after delivery to the applicable Seller of proof of such payment, such Seller shall pay to Purchaser the amount of such Periodic Non-Income Taxes paid by Purchaser.

(b) With respect to any Periodic Non-Income Taxes that are assessed on, or in respect of, the Purchased Assets and attributable to any period which

11.3 Injunctive Relief.

(a) The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement or the Ancillary Agreements (as applicable) were not performed in accordance with their specific terms or were otherwise breached, and that damages at law may be an inadequate remedy for the breach of any of the covenants, promises and agreements contained in this Agreement or the Ancillary Agreements (as applicable), and, accordingly, any party hereto shall be entitled to injunctive relief to prevent any such breach, and to specifically enforce specifically the terms and provisions of this Agreement or the Ancillary Agreements (as applicable), including without limitation specific performance of such covenants, promises or agreements or an order enjoining a party from any threatened, or from the continuation of any actual, breach of the covenants, promises or agreements contained in this Agreement or the Ancillary Agreements (as applicable).

If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby 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, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the

No assignment of this Agreement or of any rights or obligations hereunder may be made by either the Sellers or Purchaser (by operation of law or otherwise) without the prior written consent of the other parties hereto (and in the case of any assignment by a Seller, such assignment shall also require the prior written consent of the Required Lenders) and any attempted assignment without the required consents shall be void; provided, however, that (a) Purchaser may assign some or all of its rights or delegate some or all of its obligations hereunder to one or more of its Affiliates and (b) the Sellers may assign some or all of their rights or delegate some or all of their obligations hereunder to successor entities (including any liquidating trust) pursuant to a Chapter 11 plan confirmed by the Bankruptcy Court. No assignment of any obligations hereunder shall relieve the parties hereto of any such obligations. Upon any such permitted assignment, the references in this Agreement to the Sellers or Purchaser shall also apply to any such assignee unless the context otherwise requires.

11.11 Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner or equityholder of the parties to this Agreement shall have any liability for any obligations or liabilities of the Sellers or Purchaser, as applicable, under this Agreement or any agreement entered into in connection herewith of or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby and thereby. Any claim or cause of action based upon, arising out of, or related to this Agreement or any agreement, document or instrument contemplated hereby may only be brought against Persons that are expressly named as parties hereto or thereto, and then only with respect to the specific obligations set forth herein or therein. Other than the parties hereto, no other party shall have any liability or obligation for any of the representations, warranties, covenants, agreements, obligations or liabilities of any party under this Agreement or the agreements, documents or instruments contemplated hereby or of or for any Legal Proceeding based on, in respect of, or by reason of, the transactions contemplated hereby or thereby (including the breach, termination or failure to consummate such transactions), in each case whether based on contract, tort, fraud, strict liability, other Laws or otherwise and whether by piercing the corporate veil, by a claim by or on behalf of a party hereto or another Person or otherwise.
