Additionally, subject to Section 2.6(e), each Commitment Party shall have the right to Transfer all or any portion of its Commitments to any creditworthy Related Purchaser, provided, that such Commitment Party shall (i) provide written notice to the Company of such Transfer as far in advance thereof as practicable and (ii) deliver to the Company, the Rights Offering Subscription Agent and Milbank a joinder to this Agreement, substantially in the form attached hereto as Exhibit B, executed by such Commitment Party and such Related Purchaser. (c) Subject to Section 2.6(e), each Commitment Party shall have the right to Transfer all or any portion of its Commitments to any other Commitment Party or such other Commitment Party’s Related Purchaser (each, an “Existing Commitment Party Purchaser”), provided, that (i) such Existing Commitment Party Purchaser or such Existing Commitment Party Purchaser’s Affiliate or Affiliated Fund shall have been a Commitment Party as of immediately prior to such Transfer and (ii)(1) to the extent such Existing Commitment Party Purchaser is not a Commitment Party hereunder, such Commitment Party shall deliver to the Company, the Rights Offering Subscription Agent and Milbank a joinder to this Agreement, substantially in the form attached hereto as Exhibit C-1, executed by such Commitment Party and such Existing Commitment Party Purchaser and (2) to the extent such Existing Commitment Party Purchaser is already a Commitment Party hereunder, such Commitment Party shall deliver to the Company, the Rights Offering Subscription Agent and Milbank an amendment to this Agreement, substantially in the form attached hereto as Exhibit C-2, executed by such Commitment Party and such Existing Commitment Party Purchaser.

A Commitment Party shall have the right to Transfer all or any portion of its Commitments to any other Person pursuant to the terms of this Agreement whether or not it is making a simultaneous transfer of a corresponding amount of the Note Claims. For the avoidance of doubt, it is the intent of the Parties that a Transfer of the Commitments pursuant to this Section 2.6 will represent a transfer of proportional portions of the Rights Offering Backstop Commitment and the 4(a)(2) Backstop Commitment and that, accordingly, any Transfer of such Commitment Party’s Rights Offering Backstop Commitment or 4(a)(2) Backstop Commitment shall be permitted only if coupled by a proportional Transfer of the other.

Any Transfer made (or attempted to be made) in violation of this Agreement shall be deemed null and void ab initio and of no force or effect, regardless of any prior notice provided to the Parties or any Commitment Party, and shall not create (or be deemed to create) any obligation or liability of any other Commitment Party or any Debtor to the purported transferee or limit, alter or impair any agreements, covenants, or obligations of the proposed transferor under this Agreement. After the Closing Date, nothing in this Agreement shall limit or restrict in any way the ability of any Commitment Party (or any permitted transferee thereof) to Transfer any of the Common Units or any interest therein. (f) Any Person that is Transferred a Joinder Commitment by a Joinder Commitment Party in compliance with the terms of this Section 2.6 shall be a Joinder Commitment Party with respect to such Commitment, as applicable, for all purposes herein.

Such purchase shall be effected by making a payment to the agent for the Exit Term Loan for the benefit of such lenders pursuant to Section 2.5(d). The obligations of the Exit Term Loan Commitment Parties to purchase such Exit Term Loans as described in this Section 2.7 shall be referred to as the “Exit Term Loan Backstop Commitment”. To the extent a Joinder Commitment Party agrees to backstop their Required Exit Term Loan Share of the Exit Term Loan Backstop Commitment by the Required Exit Term Loan Commitment Date, the Exit Term Loan Backstop Commitment of each Senior Commitment Party shall be ratably reduced and Schedule 2 shall be amended to add the Exit Term Loan Backstop Commitment of such Joinder Commitment Party, provided that before and after such adjustment, the sum of the Exit Term Loan Backstop Commitments shall equal $31,250,000.

The provisions for the payment of the Commitment Premium and Expense Reimbursement, and the indemnification provided herein, are an integral part of the 27

transactions contemplated by this Agreement and without these provisions the Commitment Parties would not have entered into this Agreement. Section 3.2 Payment of Commitment Premium. The Commitment Premium shall be fully earned, nonrefundable and non-avoidable upon entry of the BCA Approval Order and shall be paid by the Debtors, free and clear of any withholding or deduction for any applicable Taxes, on the Closing Date as set forth above. For the avoidance of doubt, to the extent payable in accordance with the terms of this Agreement, the Commitment Premium will be payable regardless of the amount of Unsubscribed Units (if any) actually purchased. The Company shall satisfy its obligation to pay the Commitment Premium on the Closing Date, in lieu of any cash payment, by issuing the number of additional Common Units (rounding down to the nearest whole unit solely to avoid fractional units) to each Commitment Premium Party equal to such Commitment Premium Party’s Commitment Premium Share Amount; provided, that if the Closing does not occur, the Commitment Premium shall be payable in cash and only to the extent provided in (and in accordance with) Section 9.4. The Commitment Premium and the Expense Reimbursement shall, pursuant to the BCA Approval Order, constitute allowed administrative expenses of the Debtors’ estate under sections 503(b) and 507 of the Bankruptcy Code. Section 3.3 Expense Reimbursement. (a) In accordance with and subject to the BCA Approval Order, the Debtors agree to pay, in accordance with Section 3.3(b) below, all reasonable and documented out-of- pocket fees and expenses (including travel costs and expenses) of the following attorneys, accountants, other professionals, advisors, and consultants incurred on behalf of the Commitment Parties: (i) Milbank as primary counsel to the Senior Commitment Parties, (ii) Xxxxxx Xxxxxx LLP, as co-counsel to the Senior Commitment Parties, (iii) X.X.

The Expense Reimbursement shall, pursuant to the BCA Approval Order, constitute allowed administrative expenses against each of the Debtors’ estates under sections 503(b) and 507 of the Bankruptcy Code. For the avoidance of doubt, the amount payable pursuant to this Section 3.3 shall be determined without duplication of recovery under the Restructuring Support Agreement. (b) The Expense Reimbursement accrued through the date on which the BCA Approval Order is entered shall be paid in accordance with the DIP Orders and BCA Approval Order as promptly as reasonably practicable after the date of the entry of the BCA Approval Order. The Expense Reimbursement shall thereafter be payable on a monthly basis by the Debtors in accordance with the BCA Approval Order; provided, that the Debtors’ final payment shall be made contemporaneously with the Closing or the termination of this Agreement pursuant to Article IX. 28

The Indemnifying Party shall not, without the prior written consent of an Indemnified Person (which consent shall be granted or withheld, conditioned or delayed 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 58

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, on the other hand, shall be deemed to be in the same proportion as (a) the total value received or proposed to be received by the Company pursuant to the issuance and sale of the Unsubscribed Units in the Rights Offering or the sale of the 4(a)(2) Backstop Commitment Units in the 4(a)(2) Backstop Commitment Investment contemplated by this Agreement and the P lan bears to (b) the Commitment Premium paid or proposed to be paid to the Commitment Parties. 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. Section 8.5 Treatment of Indemnification Payments. All amounts paid by an Indemnifying Party to an Indemnified Person under this Article VIII shall, to the extent permitted by applicable Law, be treated as adjustments to the Per Unit 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 Commitment Parties would not have entered into this Agreement. The BCA Approval Order shall provide that 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 that the Company may comply with the requirements of this Article VIII without further Order of the Bankruptcy Court. Section 8.6 No Survival. All representations, warranties, covenants and agreements made in this Agreement shall not survive the Closing Date except for covenants and agreements that by their terms are to be satisfied after the Closing Date, which covenants and agreements shall survive until satisfied in accordance with their terms. ARTICLE IX TERMINATION Section 9.1 Consensual Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing Date by mutual written consent of the Company and the Requisite Commitment Parties. Section 9.2 Automatic Termination. Notwithstanding anything to the contrary in this Agreement, unless and until there is an unstayed Order of the Bankruptcy Court providing that the giving of notice under and/or termination of this Agreement in accordance with its terms is not prohibited by the automatic stay imposed by section 362 of the Bankruptcy Code, and except as otherwise provided in this Section 9.2, at which point this Agreement may be terminated by the Requisite Commitment Parties upon written notice to the Company upon the occurrence of any of the following Events, this Agreement shall terminate automatically without any further action or notice by any Party at 5:00 p.m., New York City time on the fifth Business Day following the occurrence of any of the following Events; provided that, 59

the Requisite Commitment Parties may waive such termination or extend any applicable dates in accordance with Section 10.7: (a) the Closing Date has not occurred by 11:59 p.m., New York City time on July 6, 2017 (as it may be extended pursuant to this Section 9.2(a) or Section 2.3, the “Outside Date”), unless prior thereto the Effective Date occurs and each of the Transactions have been consummated; provided, that the Outside Date may be waived or extended with the prior written approval of the Requisite Commitment Parties; provided, further, that if any Commitment Party does not consent to a waiver or extension of the Outside Date beyond 5:00 p.m., New York City time on February 24, 2018 the (“End Date”) within seven (7) days of a written request being made either by the Company or by any other Commitment Party for such a waiver or extension (which request was made no later than the date seven (7) days prior to the Outside Date and has not been withdrawn) and such waiver or extension is duly approved by the Requisite Commitment Parties, such Commitment Party shall be deemed a Non-Consenting Commitment Party who has elected to withdraw from its Commitments and Exit Term Loan Backstop Commitment, as applicable, pursuant to Section 6.16 (Withdrawal of Commitment Party) and shall no longer be a party to this Agreement or the Restructuring Support Agreement (and, for the avoidance of doubt, such Commitment Party shall not be entitled to receive any portion of the Commitment Premium); (b) the Restructuring Support Agreement is terminated as to the Debtors or the Consenting Senior Note Holders (as defined in the Restructuring Support Agreement) in accordance with its terms; (c) the Company or any of the other Debtors files any motion, application or adversary proceeding (or any of the Company, any of the other Debtors or other Restructuring Support Party supports any such motion, application, or adversary proceeding filed or commenced by any third party) (i) challenging the validity, enforceability, or priority of, or seeking avoidance or subordination of the Note Claims, or (ii) asserting any other cause of action against and/or with respect to or relating to such claims; (d) (i) the Company or the other Debtors shall have breached any representation, warranty, covenant or other agreement made by the Company or the other Debtors in this Agreement or any such representation or warranty shall have become inaccurate and such breach or inaccuracy would, individually or in the aggregate, cause a condition set forth in Section 7.1(k) (Representations and Warranties), Section 7.1(l) (Covenants) or Section 7.1(m) (Material Adverse Effect) not to be satisfied, (ii) the Commitment Parties shall have delivered written notice of such breach or inaccuracy to the Company, (iii) such breach or inaccuracy is not cured by the Company or the other Debtors by the tenth (10th) Business Day after receipt of such notice, and (iv) as a result of such failure to cure, any condition set forth in Section 7.1(k) (Representations and Warranties), Section 7.1(l) (Covenants), or Section 7.1(m) (Material Adverse Effect) is not capable of being satisfied; provided, that, this Agreement shall not terminate automatically pursuant to this Section 9.2(d) if the Commitment Parties are then in willful or intentional breach of this Agreement; (e) any Law or final and non-appealable Order shall have been enacted, adopted or issued by any Governmental Entity that prohibits the implementation of the Plan or 60

the Transactions or the transactions contemplated by this Agreement or the other Transaction Agreements, in a way that cannot be remedied by the Debtors in a manner reasonably acceptable to the Requisite Commitment Parties; (f) (i) the Debtors have materially breached their obligations under Section 6.13 (Alternative Transactions); (ii) the Bankruptcy Court approves or authorizes an Alternative Transaction; or (iii) any of the Debtors enters into any Contract providing for the consummation of any Alternative Transaction or files any motion or application seeking authority to propose, join in or participate in the formation of, any actual or proposed Alternative Transaction; (g) the Company or any other Debtor (i) amends or modifies, or files a pleading seeking authority to amend or modify, the Definitive Documentation in a manner that is materially inconsistent with this Agreement; (ii) suspends or revokes the Transaction Agreements; or (iii) publicly announces its intention to take any such action listed in sub-clauses (i) or (ii) of this subsection; (h) any of the BCA Approval Order, P lan Solicitation Order or Confirmation Order is terminated, reversed, stayed, dismissed, vacated, or reconsidered, or any such Order is modified or amended after entry without the prior written consent (not to be unreasonably withheld, conditioned or delayed) of the Requisite Commitment Parties in a manner that prevents or prohibits the consummation of the transactions contemplated by this Agreement or the other Transaction Agreements in a way that cannot be remedied by the Debtors in a manner reasonably acceptable to the Requisite Commitment Parties; (i) any of the Orders approving the Exit RBL Facility, the Exit Term Loans, this Agreement, the Rights Offering Procedures, the Plan or the Disclosure Statement or the Confirmation Order are reversed, stayed, dismissed, vacated or reconsidered or modified or amended without the acquiescence or written consent (not to be unreasonably withheld, conditioned or delayed) of the Requisite Commitment Parties (and such action has not been reversed or vacated within thirty (30) calendar days after its issuance) in a manner that prevents or prohibits the consummation of the Restructuring Transactions contemplated in this Agreement or any of the Definitive Documents in a way that cannot be remedied by the Debtors subject to the reasonable satisfaction of the Requisite Commitment Parties; or (j) an acceleration of the obligations or termination of commitments under the DIP Facility. Section 9.3 Termination by the Company.

(d) the BCA Approval Order, Plan Solicitation Order, or Confirmation Order is terminated, reversed, stayed, dismissed, vacated, or reconsidered, or any such Order is modified or amended after entry without the prior acquiescence or written consent (not to be unreasonably withheld, conditioned or delayed) of the Company in a manner that prevents or prohibits the consummation of the Restructuring Transactions contemplated in this Agreement or any of the Definitive Documents in a way that cannot be remedied by the Commitment Parties subject to the reasonable satisfaction of the Debtors; (e) the Restructuring Support Agreement is terminated in accordance with its terms; (f) any of the Orders approving the Exit RBL Facility, the Exit Term Loans, this Agreement, the Rights Offering Procedures, the Plan or the Disclosure Statement or the Confirmation Order are reversed, stayed, dismissed, vacated or reconsidered or modified or amended without the acquiescence or consent (not to be unreasonably withheld, conditioned or delayed) of the Company (and such action has not been reversed or vacated within thirty (30) calendar days after its issuance) in a manner that prevents or prohibits the consummation of the Restructuring Transactions contemplated in this Agreement or any of the Definitive Documents in a way that cannot be remedied by the Commitment Parties subject to the reasonable satisfaction of the Debtors; or 62

(g) the Closing Date has not occurred by the earlier of (i) the Outside Date (as the same may be extended pursuant to Section 9.2(a) or Section 2.3), and (ii) the date that is two hundred seventy (270) days from the date hereof, in either case, unless prior thereto the Effective Date occurs and each of the Transactions have been consummated; provided, that the Company shall not have the right to terminate this Agreement pursuant to this Section 9.3(g) if it is then in material breach of this Agreement. Section 9.4 Effect of Termination. (a) Upon termination of this Agreement pursuant to this Article IX, this Agreement shall forthwith become void and there shall be no further obligations or liabilities on the part of the Parties; provided, that (i) the obligations of the Debtors to pay the Expense Reimbursement pursuant to Article III and to satisfy their indemnification obligations pursuant to Article VIII shall survive the termination of this Agreement and shall remain in full force and effect, in each case, until such obligations have been satisfied, (ii) the provisions set forth in Article VIII, this Section 9.4 and Article X shall survive the termination of this Agreement in accordance with their terms and (iii) subject to Section 10.10 (Damages), nothing in this Section 9.4 shall relieve any Party from liability for its gross negligence or any willful or intentional breach of this Agreement. For purposes of this Agreement, “willful or intentional breach” means a breach of this Agreement that is a consequence of an act undertaken by the breaching Party with the knowledge that the taking of such act would, or would reasonably be expected to, cause a breach of this Agreement. (b) The Debtors shall make payments to the Commitment Premium Parties or their designees based upon their respective Commitment Premium Share Amount on the date of payment, by wire transfer of immediately available funds to such accounts as the Requisite Commitment Parties may designate, if this Agreement is terminated as follows: (i) upon termination pursuant to: (A) Section 9.2(c) (Adversary Proceeding), Section 9.2(d) (Breach) (unless such termination is the result of a breach not within the control of the Debtors) or Section 9.2(f) (Alternative Transactions); (B) Section 9.2(a) (Outside Date) where the failure of the Closing Date to occur prior to the Outside Date results from the Company’s breach of this Agreement (it being understood that a failure of the Closing Date to occur prior to the Outside Date arising from events not within the control of the Debtors (such as, for example, the failure to satisfy the condition set forth in Section 7.1(t) (Hedging) notwithstanding the Company’s compliance with its obligations under Section 6.14) shall not constitute a termination covered by this clause (B)); or (C) Section 9.2(b) (Restructuring Support Agreement) or Section 9.3(e) (Restructuring Support Agreement), in either case as a result of (x) a termination of the Restructuring Support Agreement pursuant to Section 9(c) thereof or (y) a termination of the Restructuring Support Agreement by the Required Consenting Senior Note Holders (as defined therein) arising from a breach of the Restructuring Support Agreement by the Debtors unless such breach is the result of (I) actions of the Bankruptcy Court not arising from any action or omission by the Debtors or (II) any other events not within the control of the Debtors (such as, for example, the failure to meet any Milestone (as defined in the Restructuring 63

Support Agreement) notwithstanding the fact that the Company has taken all reasonably necessary actions to comply with the Milestone and has otherwise complied with its obligations under the Restructuring Support Agreement, it being understood and agreed that in the event that revisions or modifications to the Plan are required to render it confirmable, the failure of the Parties to agree to such modifications or amendments or the failure of the Parties to agree on the resolution of any blank or bracketed terms in the P lan prior to the Outside Date shall not constitute a termination covered by this clause (C)); then, in the case of each of clauses (A), (B) and (C), the Company shall pay the Commitment Premium, in cash, on or prior to the second (2nd) Business Day following such termination; and (ii) if the Company shall terminate this Agreement pursuant to Section 9.3(c) (Fiduciary Duties), then the Company shall pay the Commitment Premium, in cash, concurrently with such termination. To the extent that all amounts due in respect of the Commitment Premium pursuant to this Section 9.4(b) have actually been paid by the Debtors to the Commitment Premium Parties in connection with a termination of this Agreement, the Commitment Parties 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 gross negligence or willful or intentional breach of this Agreement pursuant to Section 9.4(a). Except as set forth in this Section 9.4(b), the Commitment Premium shall not be payable upon the termination of this Agreement. ARTICLE X GENERAL PROVISIONS Section 10.1 Notices.

Exhibit A-1 1145 Rights Offering Procedures See attached.

VANGUARD NATURAL RESOURCES, LLC (THE “COMPANY”), ON BEHALF OF VNR FINANCE CORP. (AS REORGANIZED PURSUANT TO AND UNDER THE PLAN, OR ANY SUCCESSOR THERETO) 1145 RIGHTS OFFERING PROCEDURES The 1145 Rights Offering Equity is being distributed and issued by the Debtors without registration under the Securities Act of 1933, as amended (the “Securities Act”)1, in reliance upon the exemption provided in Section 1145 of the Bankruptcy Code. None of the rights being offered in the 1145 Rights Offering (the “Rights”) or the 1145 Rights Offering Equity issuable upon exercise of such rights distributed pursuant to these offering procedures (the “1145 Rights Offering Procedures”) have been or will be registered under the Securities Act, nor any state or local law requiring registration for offer and sale of a security. The record ownership of the Rights is not transferable. The Disclosure Statement (as defined below) has previously been distributed in connection with the Debtors’ solicitation of votes to accept or reject the Plan (as defined below) and that document sets forth important information, including risk factors, that should be carefully read and considered by each 1145 Eligible Holder (as defined below) prior to making a decision to participate in the 1145 Rights Offering. Additional copies of the Disclosure Statement are available upon request from Prime Clerk LLC (the “Rights Offering Subscription Agent”). The 1145 Rights Offering is being conducted by the Company on behalf of Reorganized VNR in good faith and in compliance with the Bankruptcy Code. In accordance with Section 1125(e) of the Bankruptcy Code, a debtor or any of its agents that participate, in good faith and in compliance with the applicable provisions of the Bankruptcy Code, in the offer, issuance, sale, or purchase of a security offered or sold under the plan of the debtor, of an affiliate participating in a joint plan with the debtor, or of a newly organized successor to the debtor under the plan, is not liable, on account of such participation, for violation of any applicable law, rule, or regulation governing the offer, issuance, sale or purchase of securities. 1 Terms used and not defined herein shall have the meaning assigned to them in the Joint Plan of Reorganization of Vanguard Natural Resources, LLC, et al., Pursuant to Chapter 11 of the Bankruptcy Code (as may be amended, modified, or supplemented from time to time, the “Plan”).

1145 Eligible Holders should note the following times relating to the 1145 Rights Offering: Date Calendar Date Event Record Date………………………. June 7, 2017 The date and time fixed by the Company for the determination of the holders eligible to participate in the 1145 Rights Offering. Subscription Commencement Date .. June 12, 2017 Commencement of the 1145 Rights Offering. Subscription Expiration Deadline … 4:00 p.m. Central Time on June 30, 2017 The deadline for 1145 Eligible Holders to subscribe for 1145 Rights Offering Equity. An 1145 Eligible Holder’s applicable 1145 Beneficial Holder Subscription Form(s) (as defined below) must be received by the 1145 Eligible Holder’s Nominee (as defined below) in sufficient time to allow such Nominee to deliver the Master 1145 Subscription Form (as defined below) to the Rights Offering Subscription Agent by the Subscription Expiration Deadline. 1145 Eligible Holders who are not Backstop Parties must deliver the aggregate Purchase Price (as defined below) by the Subscription Expiration Deadline. 1145 Eligible Holders who are Backstop Parties must deliver the aggregate Purchase Price no later than the deadline specified in the

Funding Notice (as defined below) in accordance with the terms of the Backstop Agreement.

To 1145 Eligible Holders and Nominees of 1145 Eligible Holders: On May 31, 2017, the Debtors filed the Plan with the United States Bankruptcy Court for the Southern District of Texas and the Disclosure Statement Relating to the Joint Plan of Reorganization of Vanguard Natural Resources, LLC, et al., Pursuant to Chapter 11 of the Bankruptcy Code (as may be amended from time to time in accordance with its terms, the “Disclosure Statement”). Pursuant to the Plan, each holder of an Allowed Senior Notes Claim as of the Record Date (as defined in the 1145 Beneficial Holder Subscription Form) (each such holder, an “1145 Eligible Holder”) has a right to participate in the 1145 Rights Offering, in accordance with the terms and conditions of these 1145 Rights Offering Procedures. Pursuant to the Plan, in the 1145 Rights Offering, each 1145 Eligible Holder will receive rights to subscribe for its pro rata portion of a rights offering of 1145 Rights Offering Equity in an aggregate amount of $10,176,081 provided that it timely and properly executes and delivers the attached 1145 Beneficial Holder Subscription Form (with accompanying IRS Form W-9 or appropriate IRS Form W-8, as applicable) (the “1145 Beneficial Holder Subscription Form”) to the Rights Offering Subscription Agent or its Nominee, as applicable, in advance of the Subscription Expiration Deadline. Included with the 1145 Beneficial Holder Subscription Form, each such Nominee will receive a Master 1145 Subscription Form (a “Master 1145 Subscription Form”) which it shall use to summarize the Rights exercised by each 1145 Eligible Holder that timely returns the applicable properly filled out 1145 Beneficial Holder Subscription Form(s) to such Nominee. 1145 Beneficial Holder Subscription Forms should only be returned directly to the Rights Offering Subscription Agent if the 1145 Eligible Holder is the direct holder of record on the books of the applicable indenture trustee and does not hold its Allowed Senior Notes Claim through a Nominee. Please note that all 1145 Beneficial Holder Subscription Forms must be returned to the applicable Nominee in sufficient time to allow such Nominee to process and deliver the Master 1145 Subscription Form and copies of all 1145 Beneficial Holder Subscription Forms, and the accompanying IRS Forms prior to the Subscription Expiration Deadline. To the extent of any discrepancy between the Master 1145 Subscription Form and the 1145 Beneficial Holder Subscription Form(s) regarding the 1145 Eligible Holder’s principal amount, the Master 1145 Subscription Form shall govern. While the amount of time necessary for a Nominee to process and deliver the Master 1145 Subscription Form to the Rights Offering Subscription Agent will vary from Nominee to Nominee, 1145 Eligible Holders are urged to consult with their Nominees to determine the necessary deadline to return their 1145 Beneficial Holder Subscription Forms. Failure to submit such 1145 Beneficial Holder Subscription Forms on a timely basis will result in forfeiture of an 1145 Eligible Holder’s rights to participate in the 1145 Rights Offering. None of the Company, the Rights Offering Subscription Agent or any of the Backstop Parties will have any liability for any such failure. No 1145 Eligible Holder shall be entitled to participate in the 1145 Rights Offering unless the aggregate Purchase Price (as defined below) for the 1145 Rights Offering Equity it subscribes for is received by the Rights Offering Subscription Agent (i) in the case of an 1145 Eligible Holder that is not a Backstop Party, by the Subscription Expiration Deadline, and (ii)

in the case of an 1145 Eligible Holder that is a Backstop Party, no later than the deadline specified in a written notice (a “Funding Notice”) delivered by or on behalf of the Debtors to the Backstop Parties in accordance with Section 2.4 of the Backstop Agreement (the “Backstop Funding Deadline”), provided that the Backstop Parties may deposit their aggregate Purchase Price in the Escrow Account (as defined below), in accordance with the terms of the Backstop Agreement. No interest is payable on any advanced funding of the Purchase Price. If the 1145 Rights Offering is terminated for any reason, the aggregate Purchase Price previously received by the Rights Offering Subscription Agent will be returned to 1145 Eligible Holders as provided in Section 6 hereof. No interest will be paid on any returned Purchase Price. Any 1145 Eligible Holder who is not a Backstop Party submitting payment via its Nominee must coordinate such payment with its Nominee in sufficient time to allow the Nominee to forward such payment to the Rights Offering Subscription Agent by the Subscription Expiration Deadline. In order to participate in the 1145 Rights Offering, an 1145 Eligible Holder must complete all of the steps outlined below. If all of the steps outlined below are not completed by the Subscription Expiration Deadline or the Backstop Funding Deadline, as applicable, an 1145 Eligible Holder shall be deemed to have forever and irrevocably relinquished and waived its right to participate in the 1145 Rights Offering. 1. 1145 Rights Offering 1145 Eligible Holders have the right, but not the obligation, to participate in the 1145 Rights Offering. 1145 Eligible Holders shall receive rights to subscribe for their pro rata portion of the 1145 Rights Offering Equity. Subject to the terms and conditions set forth in the Plan and these 1145 Rights Offering Procedures, each 1145 Eligible Holder is entitled to subscribe for up to:  1.550362 1145 Rights Offering Equity per $1,000 of principal amount of the 8 3/8% Senior Notes due 2019; and  1.569156 1145 Rights Offering Equity per $1,000 of principal amount of the 7.875% Senior Notes due 2020; in each case at a purchase price of $15 per share (the “Purchase Price”). The difference in the number of 1145 Rights Offering Equity that an 1145 Eligible Holder is entitled to subscribe for with respect to each series of Senior Notes is to take into account the differing amounts of pre-petition accrued and unpaid interest thereon. There will be no over-subscription privilege in the 1145 Rights Offering. Any 1145 Rights Offering Equity that are unsubscribed by the 1145 Eligible Holders entitled thereto will not be offered to other 1145 Eligible Holders but will be purchased by the applicable Backstop Parties in accordance with the Backstop Agreement. Subject to the terms and conditions of the Backstop Agreement, each Backstop Party is obligated to

purchase its pro rata portion of the applicable 1145 Rights Offering Equity. Any 1145 Eligible Holder that subscribes for 1145 Rights Offering Equity and is deemed to be an “underwriter” under 1145(b) of the Bankruptcy Code will be subject to restrictions under the Securities Act on its ability to resell those securities. Resale restrictions are discussed in more detail in Article XII of the Disclosure Statement, entitled “Certain Securities Law Matters.” SUBJECT TO THE TERMS AND CONDITIONS OF THE 1145 RIGHTS OFFERING PROCEDURES AND THE BACKSTOP AGREEMENT IN THE CASE OF ANY BACKSTOP PARTY, ALL SUBSCRIPTIONS SET FORTH IN THE APPLICABLE 1145 BENEFICIAL HOLDER SUBSCRIPTION FORM(S) ARE IRREVOCABLE. 2. Subscription Period The 1145 Rights Offering will commence on the Subscription Commencement Date and will expire at the Subscription Expiration Deadline. Each 1145 Eligible Holder intending to purchase 1145 Rights Offering Equity in any 1145 Rights Offering must affirmatively elect to exercise its Rights in the manner set forth in the applicable 1145 Beneficial Holder Subscription Form by the Subscription Expiration Deadline. Any exercise of Rights by an 1145 Eligible Holder after the Subscription Expiration Deadline will not be allowed and any purported exercise received by the Rights Offering Subscription Agent after the Subscription Expiration Deadline, regardless of when the documents or payment relating to such exercise were sent, will not be honored, except that the Company shall have the discretion, with the consent of the Senior Commitment Parties holding at least two-thirds of the aggregate Backstop Commitments (as identified in Schedule 1 to the Backstop Agreement) as of the date on which such consent is solicited (the “Requisite Commitment Parties”), to allow any exercise of Rights after the Subscription Expiration Deadline. The Subscription Expiration Deadline may be extended with the consent of the Requisite Commitment Parties, or as required by law.

3. Delivery of Subscription Documents Each 1145 Eligible Holder may exercise all or any portion of such 1145 Eligible Holder’s Rights, but subject to the terms and conditions contained herein. In order to facilitate the exercise of the Rights, beginning on the Subscription Commencement Date, the applicable 1145 Beneficial Holder Subscription Form and these 1145 Rights Offering Procedures will be sent to each 1145 Eligible Holder, together with appropriate instructions for the proper completion, due execution and timely delivery of the executed 1145 Beneficial Holder Subscription Form and the payment of the applicable aggregate Purchase Price for its 1145 Rights Offering Equity. Distribution by the Rights Offering Subscription Agent of the 1145 Beneficial Holder Subscription Form and these procedures to the Nominees reflected on the securities position report provided by DTC as of the Record Date (with instructions to forward such documents to the Nominees’ beneficial holder clients) and/or posting of these procedures and 1145 Beneficial Holder Subscription Form on DTC’s LENS Noticing System shall constitute valid and sufficient delivery of such documents, and satisfy the obligations of the Rights Offering Subscription Agent with respect thereto. Nominees may utilize an agent to distribute the 1145 Subscription Form and these procedures to their beneficial holder clients and seek reasonable reimbursement of the costs associated therewith by submitting a timely invoice to the Rights Offering Subscription Agent. 4. Exercise of Rights (a) In order to validly exercise its Rights, each 1145 Eligible Holder that is not a Backstop Party must: i. return duly completed and executed applicable 1145 Beneficial Holder Subscription Form(s) to the Rights Offering Subscription Agent or its Nominee, as applicable, so that, if applicable, such documents may be transmitted to the Rights Offering Subscription Agent by the Nominee, so that such documents are actually received by the Rights Offering Subscription Agent by the Subscription Expiration Deadline; and ii. at the same time it returns its 1145 Beneficial Holder Subscription Form(s) to its Nominee, but in no event later than the Subscription Expiration Deadline, arrange for the payment by its Nominee of, the applicable Purchase Price to the Rights Offering Subscription Agent by wire transfer ONLY of immediately available funds in accordance with the instructions included in the applicable 1145 Beneficial Holder Subscription Form(s).

The Debtors intend that the 1145 Rights Offering Equity will be issued to the 1145 Eligible Holders and/or to any party that an 1145 Eligible Holder so designates in the 1145 Beneficial Holder Subscription Form(s), in book-entry form, and that DTC, or its nominee, will be the holder of record of such 1145 Rights Offering Equity. To the extent DTC is unwilling or unable to make the 1145 Rights Offering Equity eligible on the DTC system, the 1145 Rights Offering Equity will be issued directly to the 1145 Eligible Holder or its designee. 8. Fractional Shares No fractional rights or 1145 Rights Offering Equity will be issued in the 1145 Rights Offering.

Please note that all Accredited Investor Beneficial Holder Subscription Forms must be returned to the applicable Nominee in sufficient time to allow such Nominee to process and deliver the Master Accredited Investor Subscription Form and copies of all Accredited Investor Beneficial Holder Subscription Forms, and the accompanying IRS Forms and Accredited Investor Questionnaires prior to the Subscription Expiration Deadline.

In so doing, and subject to the consent of the Requisite Commitment Parties, the Debtors may execute and enter into agreements and take further action that the Debtors determine in good faith is necessary and appropriate to effectuate and implement the Accredited Investor Rights Offering and the issuance of the Accredited Investor Rights Offering Equity.
