Each Company Plan, other than any Multiemployer Plan (and each related trust, insurance Contract or fund), is in material compliance with its terms and with all applicable Laws, including ERISA and the Code. Each Company Plan, other than any Multiemployer Plan (and each related trust, if any), which is intended to be qualified under Section 401(a) of the Code has received a determination letter from the IRS to the effect that it meets the requirements of Sections 401(a) and 501(a) of the Code; no ERISA Event has occurred or is reasonably expected to occur; no ERISA Plan has an Unfunded Current Liability in an amount that exceeds $1,000,000 with respect to any single ERISA Plan and that exceeds $1,500,000 with respect to all ERISA Plans in the aggregate; all contributions required to be made with respect to a Company Plan have been or will be timely made (except as disclosed on Section 4.21(a) of the Company Disclosure Schedule); using actuarial assumptions and computation methods consistent with Part 1 of subtitle E of Title IV of ERISA, the Company and its Subsidiaries and ERISA Affiliates would have no material liabilities to any Multiemployer Plans in the event of a complete withdrawal therefrom; each group health plan (as defined in Section 607(1) of ERISA or Section 4980B(g)(2) of the Code) that covers or has covered employees or former employees of the Company, any of its Subsidiaries, or any ERISA Affiliate has at all times during the past three years been operated in material compliance with the provisions of Part 6 of subtitle B of Title I of ERISA and Section 4980B of the Code.

All material contributions required to be made with respect to a Foreign Pension Plan have been or will be timely made. Neither the Company nor any of its Subsidiaries has incurred any material obligation in connection with the termination of or withdrawal from any Foreign Pension Plan. Neither the Company nor any of its Subsidiaries maintains or contributes

to any Foreign Pension Plan the obligations with respect to which would in the aggregate reasonably be expected to have a Material Adverse Effect.  

Section 4.22 Disclosure Controls and Procedures. Based upon the most recent evaluation by the Chief Executive Officer and Chief Financial Officer of the Company of the Company’s internal control over financial reporting, there are no (a) significant deficiencies or material weaknesses in the design or operation of the Company’s internal control over financial reporting which are reasonably likely to adversely affect its ability to record, process, summarize and report financial data or (b) fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting.

Other than as a result of the filing of the Chapter 11 Proceedings or the Recognition Proceedings, neither the Company nor any of its Subsidiaries nor, to the Knowledge of the Company, any other party to any Material Contract, is in material default or breach under the terms thereof. The Company has provided or made available to the Plan Sponsors true, correct and complete copies of each Material Contract as of the date hereof.

The Company will not directly or indirectly use the proceeds from this Agreement (including the Emergence Equity Purchase, the Additional Capital Commitment or the sale of the Additional Capital Commitment Units), or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person, for the purpose of financing the activities of any Person that, to the Knowledge of the Company, is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the United States Treasury Department.

Section 4.27 No Broker’s Fees. Neither the Company nor any of its Subsidiaries is a party to any Contract with any Person (other than this Agreement) that would give rise to a valid claim against the Plan Sponsors for a brokerage commission, finder’s fee or like payment in connection with the Emergence Equity Purchase, the Additional Capital Commitment or the sale of the Emergence Equity Units or the Additional Capital Commitment Units or the transactions contemplated hereby or thereby.

As of the date hereof, to the Knowledge of the Company, neither the Company nor any of its Subsidiaries has received notice from any insurer or agent of such insurer with respect to any material insurance policies of the Company and its Subsidiaries of cancellation or termination of such policies, other than such notices

which are received in the ordinary course of business or for policies that have expired in accordance with their terms.

Any purported Transfer of Votable Claims or Additional Claims not in accordance with this Section 6.5 will be void ab initio.

Any such applicable Reorganized Holdings Corporate Document or similar agreement shall be adopted on the Effective Date and shall be deemed to be valid, binding and enforceable in accordance with its terms, and each Plan Sponsor shall be bound thereby.

None of the Company or any of its affiliates (as defined in Rule 501(b) of Regulation D promulgated under the Securities Act) or any other Person acting on its or their behalf will solicit offers for, or offer or sell, any Emergence Equity Units or Additional Capital Commitment Units by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D promulgated under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED ON [DATE OF ISSUANCE], HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY OTHER APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN AVAILABLE EXEMPTION FROM REGISTRATION THEREUNDER.”

In the event that any such Emergence Equity Units are uncertificated, such units shall be subject to a restrictive notation substantially similar to the Legend in the stock ledger or other appropriate records maintained by the Company or agent and the term “Legend” shall include such restrictive notation. The Company shall remove the Legend (or restrictive notation, as applicable) set forth above from the certificates evidencing any such Emergence Equity Units (or the Company’s stock records, in the case of uncertified units) at any time after the restrictions described in such Legend cease to be applicable, including, as applicable, when such units may be sold under Rule 144. The Company may reasonably request such opinions, certificates or other evidence that such restrictions no longer apply.

Section 8.2 Indemnification Procedure. Promptly after receipt by an Indemnified Person of notice of the commencement of any claim, challenge, litigation, investigation or proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnifying Party in respect thereof, notify the Indemnifying Party in writing of the commencement thereof; provided, however, that (a) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have hereunder except to the extent it has been materially prejudiced by such failure and (b) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this ARTICLE VIII. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein, and, to the extent that it may elect by written notice delivered to such Indemnified Person, to assume the defense thereof, with counsel acceptable to such Indemnified Person; provided, however, that if the parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party and based on advice of such Indemnified Person’s counsel there are legal defenses available to such Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Indemnified Claims. Upon receipt of notice from the Indemnifying Party to such Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel acceptable to the Indemnified Person, the Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such Indemnified Person in connection with the defense thereof (other than reasonable costs of investigation) unless (i) such Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local counsel is required) and that all such expenses shall be reimbursed as they occur), (ii) the Indemnifying Party shall not have employed counsel acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after notice of commencement of the Indemnified Claims, (iii) the Indemnifying Party shall have failed or is failing to defend such claim, and is provided written notice of such failure by the Indemnified Person and such failure is not reasonably cured within ten (10) Business Days of receipt of such notice, or (iv) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person. Notwithstanding anything herein to the contrary, the Company and its Subsidiaries shall have sole control over any Tax controversy or Tax audit and shall be permitted to settle any liability for Taxes of the Company and its Subsidiaries.

Section 8.3 Settlement of Indemnified Claims. The Indemnifying Party shall not be liable for any settlement of any Indemnified Claims effected without its written consent (which consent shall not be unreasonably withheld). If any settlement of any Indemnified Claims is consummated with the written consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and against any and all Losses by reason of such settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, the provisions of this ARTICLE VIII. The Indemnifying Party shall not, without the prior

written consent of an Indemnified Person (which consent shall be granted or withheld in the Indemnified Person’s sole discretion), effect any settlement of any pending or threatened Indemnified Claims in respect of which indemnity or contribution has been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such Indemnified Person in form and substance satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such Indemnified Claims and (ii) such settlement does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

Section 8.4 Contribution. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 8.1, then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a result of such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons with respect to any Plan Sponsor, on the other hand, shall be deemed to be in the same proportion as the total value received or proposed to be received by the Company pursuant to the issuance and sale of the Emergence Equity Units contemplated by this Agreement and the Plan bears to such Plan Sponsor’s Purchase Percentage of the aggregate Purchase Price. The Indemnifying Parties also agree that no Indemnified Person shall have any liability based on their comparative or contributory negligence or otherwise to the Indemnifying Parties, any Person asserting claims on behalf of or in right of any of the Indemnifying Parties, or any other Person in connection with an Indemnified Claim except to the extent (a) as to a Defaulting Plan Sponsor and its Related Parties, caused by a Plan Sponsor Default by such Plan Sponsor (as found by a final, non-appealable judgment of a court of competent jurisdiction), or (b) found by a final, non-appealable judgment of a court of competent jurisdiction to arise from the bad faith, willful misconduct or gross negligence of such Indemnified Person.

Section 8.5 Treatment of Indemnification Payments. All amounts paid by the Indemnifying Party to an Indemnified Person under this ARTICLE VIII shall, to the extent permitted by applicable Law, be treated as adjustments to the Purchase Price for all Tax purposes. The provisions of this ARTICLE VIII are an integral part of the transactions contemplated by this Agreement and without these provisions the Plan Sponsors would not have entered into this Agreement, and the obligations of the Company under this ARTICLE VIII shall constitute allowed administrative expenses of the Debtors’ estate under Sections 503(b) and 507 of the Bankruptcy Code and are payable without further Order of the Bankruptcy Court, and the Company may comply with the requirements of this ARTICLE VIII without further Order of the Bankruptcy Court.

Section 8.6 No Survival.

To the extent that all amounts due in respect of the Termination Fee and the Expense Reimbursement pursuant to this Section 9.2 have actually been paid by the Debtors to the Plan Sponsors, the Plan Sponsors shall not have any additional recourse against the Debtors for any obligations or liabilities relating to or arising from this Agreement, except for liability for willful or intentional breach of this Agreement pursuant to Section 9.2.

The terms and conditions of this Agreement (other than the conditions set forth in Section 7.1 and Section 7.3, the waiver of which shall be governed solely by ARTICLE VII and the termination right set forth in Section 9.1(e), the waiver of which shall require each Plan Sponsor's prior written consent) may be waived (y) by the Debtors only by a written instrument executed by the Company and (z) by the Plan Sponsors only by a written instrument executed by the Requisite Plan Sponsors on behalf of, and which waiver shall be binding on all, Plan Sponsors. Notwithstanding anything to the contrary contained in this Agreement, the Plan Sponsors set forth on Schedule 2 may agree, among themselves, with the prior written consent of the Company (not to be unreasonably withheld), to reallocate their Purchase Percentages, without any consent or approval of any other Party; provided, however, for the avoidance of doubt, any such agreement among such Plan Sponsors shall require the consent or approval of all Plan Sponsors affected by such reallocation. No delay on the part of any Party in exercising any right, power or privilege pursuant to this Agreement will operate as a waiver thereof, nor will any waiver on the part of any Party of any right, power or privilege pursuant to this Agreement, nor will any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. Except as otherwise provided in this Agreement, the rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any Party otherwise may have at law or in equity.

Section 10.11 Headings. The headings in this Agreement are for reference purposes only and will not in any way affect the meaning or interpretation of this Agreement.

Section 10.12 Specific Performance. The Parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof, including if any of the Parties fails to take any action required of it hereunder to consummate the transactions contemplated by this Agreement, and that the Parties shall be entitled to seek an injunction or injunctions without proof of damages or posting a bond or other security to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Unless otherwise expressly stated in this Agreement, no right or remedy described or provided in this Agreement is intended to be exclusive or to preclude a Party from pursuing other rights and remedies to the extent available under this Agreement, at law or in equity. The right of specific performance and other equitable relief is an integral part of the transactions contemplated by this Agreement and without that right, neither the Company nor the Plan Sponsors would have entered into this Agreement.
