15

pertinent Insurance Contracts and applicable law.

43. Section V.J of the Plan is modified and restated as follows:

V.J Establishment of Reserves and Provisions Governing Same

Prior to the Confirmation Effective Date, the Debtors shall File a motion to establish any reserves and procedures related thereto that they deem necessary or advisable (which motion shall include, among other things, (a) certain relief with respect to the Claims Oversight Committee, consistent with Section VI.A hereof and (b) provision for payment by the Reorganized Debtors from any reserve established for the payment of Administrative Claims of the reasonable and documented post-Effective Date fees and expenses incurred by the First Lien Agent and First Lien Lenders in connection with (i) the preparation, Filing and prosecution thereof and (ii) the resolution of Claims (other than General Unsecured Claims) for which reserves are established in connection therewith), after consultation with counsel to the Creditors’ Committee and counsel to the First Lien Agent, to make Distributions to holders of Allowed Claims or otherwise to satisfy related obligations under the Plan. Such motion shall be in form and substance (a) reasonably acceptable to the Creditors’ Committee and (b) satisfactory to the First Lien Agent and the First Lien Lenders (except as it relates to General Unsecured Claims and the Claims Oversight Committee), and the Debtors shall diligently prosecute such motion after its Filing. Any Distributions held in reserve pursuant to this Section V.J shall be held in escrow until distributed pursuant to the Plan.

The Disbursing Agent shall vote, and shall be deemed to vote, any Reorganized ANR Common Stock and any NewCo Common Stock held by it in any reserve in its capacity as Disbursing Agent in the same proportion as all outstanding shares of Reorganized ANR Common Stock or NewCo Common Stock, as applicable, properly cast in a shareholder vote.

Cash dividends and other distributions received by the Disbursing Agent on account of any Reorganized ANR Common Stock and any NewCo Common Stock held in any reserve pursuant to this Section V.J will (a) be deposited in a segregated bank account in the name of the Disbursing Agent for the benefit of holders of the applicable Allowed Claims; (b) be accounted for separately; and (c) not constitute property of the Reorganized Debtors.

Any reserve established for Disputed Claims is intended to be treated, for U.S. federal income Tax purposes, as a disputed ownership fund within the meaning of Treasury Regulations section 1.468B-9(b)(1).

17

44. Section VI.B of the Plan is modified and restated as follows:

VI.B. Treatment of Disputed Claims

1. Tort Claims

At the Debtors’ or, after the Effective Date, the Reorganized Debtors’ option, any unliquidated Tort Claim (as to which a proof of Claim or request for payment of an Administrative Claim was timely Filed in the Chapter 11 Cases) not resolved through a Final Order of the Bankruptcy Court will be determined and liquidated in the administrative or judicial tribunal(s) in which it is pending on the Effective Date or, if no action was pending on the Effective Date, in any administrative or judicial tribunal of appropriate jurisdiction. The Debtors or the Reorganized Debtors, as applicable, may exercise the above option by service upon the holder of the applicable Tort Claim of a notice informing the holder of such Tort Claim that the Debtors or the Reorganized Debtors have exercised such option. Upon a Debtor’s or Reorganized Debtor’s service of such notice, the automatic stay provided under section 362 of the Bankruptcy Code or, after the Effective Date, the discharge injunction, will be deemed modified, without the necessity for further Bankruptcy Court approval, solely to the extent necessary to allow the parties, including any Insurer, to determine or liquidate the Tort Claim in the applicable administrative or judicial tribunal(s). Notwithstanding the foregoing, at all times prior to or after the Effective Date, to the fullest extent permitted by law, the Bankruptcy Court will retain jurisdiction, if any, relating to Tort Claims, including the Debtors’ right to have such Claims liquidated or estimated in the Bankruptcy Court (or the District Court) pursuant to section 157(b)(2)(B) of title 28 of the United States Code, as may be applicable. Subject to Section VI.A, any Tort Claim determined and liquidated pursuant to a judgment obtained in accordance with this Section VI.B.1 and applicable nonbankruptcy law that is no longer appealable or subject to review, and any Tort Claim that is settled by an Insurer in accordance with the terms of applicable Insurance Contracts, will be deemed an Allowed Category 1 General Unsecured Claim against the applicable Debtor in such liquidated amount, provided that only the amount of such Allowed Claim that is less than or equal to the Debtor’s self-insured retention or deductible in connection with any applicable Insurance Contract or is not otherwise satisfied from proceeds of insurance payable to the holder of such Allowed Claim under the Debtors’ Insurance Contracts will be treated as an Allowed Claim for the purposes of Distributions under the Plan. In no event will a Distribution be made under the Plan to the holder of a Tort Claim on account of any portion of an Allowed Claim in excess of the applicable Debtor’s deductible or self-insured retention under any applicable Insurance Contract. In the event a Tort Claim is determined and liquidated pursuant to a settlement, judgment or order that is obtained in accordance with this Section VI.B.1 and is no longer appealable or subject to review, and applicable nonbankruptcy law provides for no recovery against the applicable Debtor, such Tort Claim will be deemed expunged without the necessity for further Bankruptcy Court approval upon the applicable Debtor’s service of a copy of such judgment or order upon the holder of such Tort Claim, provided, however, that nothing in this sentenceSection VI.B.1 shall, or shall be deemed to, modify, alter or otherwise affect the rights of any Insurer under any Insurance Contract. Nothing contained in this Section VI.B.1 will constitute or be deemed a waiver

18

of any claim, right or Cause of Action that a Debtor may have against any Person or entity in connection with or arising out of any Tort Claim, including but not limited to any rights under section 157(b)(5) of title 28 of the United States Code. All claims, demands, rights, defenses and Causes of Action that the Debtors or the Reorganized Debtors may have against any Person in connection with or arising out of any Tort Claim are expressly retained and preserved.

45. Section VI.C.3 of the Plan is modified and restated as follows:

VI.C.3 Authority to Prosecute Objections

Subject to Section VI.A, on or after the Effective Date, only the Reorganized Debtors will have the authority to File, settle, compromise, withdraw or litigate to judgment objections to Claims. On or after the Effective Date, the Reorganized Debtors, and only the Reorganized Debtors, may settle or compromise any Disputed Claim or any objection or controversy relating to any Claim without approval of the Bankruptcy Court. Notwithstanding the foregoing, (a) the First Lien Lenders shall have the right to object to any proof of Claim or request for payment of Administrative Claim seeking allowance of any Claim that is not a General Unsecured Claim, (b) the Reorganized Debtors shall provide the First Lien Lenders with five Business Days’ notice of any proposed Filing, settlement, compromise, withdrawal or litigation to judgment of any objection to any request for payment of Administrative Claims and (c) the First Lien Lenders shall have three Business Days following receipt of such notice to provide the Reorganized Debtors with consent to any such action (with such consent not to be unreasonably withheld).
