MEANS OF IMPLEMENTATION AND POST-EFFECTIVE DATE GOVERNANCE

6.1. Corporate Action .

(a) General . Upon the occurrence of the Effective Date, all actions contemplated by this Plan shall be deemed authorized and approved in all respects, including (i) selection of the directors and officers for the Reorganized Debtors, (ii) the issuance and distribution of the New Common Stock, (iii) entry into the Joint Venture Company LLC Agreement, (iv) entry into the Contribution Agreement, (v) entry into the Management Services Agreement, (vi) entry into the JV Company Credit Facility, (vii) entry into the Exit Loan facility,

23

(viii) the adoption of the Restated Certificates of Incorporation and Restated Bylaws, (ix) entry into the New Stockholders’ Agreement, if any, (x) entry into the Recovery Trust Agreements and (xi) all other actions contemplated by this Plan (whether to occur before or on the Effective Date). All matters provided for in this Plan involving the corporate structure of the Debtors or the Reorganized Debtors, and any corporate action required by the Debtors or the Reorganized Debtors in connection with this Plan, shall be deemed to have occurred and shall be in effect, without any requirement of further action by the Equity Interest Holders, directors or officers of the Debtors or the Reorganized Debtors. On or (as applicable) prior to the Effective Date, the appropriate officers of the Debtors or the Reorganized Debtors, as applicable, shall be authorized and directed to issue, execute and deliver the agreements, documents, securities, and instruments contemplated by this Plan (or necessary or desirable to effect the transactions contemplated by this Plan) in the name of and on behalf of the Reorganized Debtors, including the JV Company Credit Facility Documents and any and all other agreements, documents, securities and instruments relating to the foregoing.

(b) Restated Certificates of Incorporation and Restated Bylaws . The Restated Bylaws and the Restated Certificates of Incorporation attached hereto as Plan Exhibits 9 and 8 , respectively, shall be (i) consistent with the provisions of this Plan and the Bankruptcy Code, and (ii) satisfactory to the Supporting Noteholders and (iii) in form and substance reasonably acceptable to the Creditors’ Committee. On or immediately before the Effective Date, the Reorganized Debtors will file their respective Restated Certificates of Incorporation with the applicable Secretaries of State and/or other applicable authorities in their respective states, provinces or countries of incorporation in accordance with the corporate laws of the respective states, provinces or countries of incorporation. Pursuant to section 1123(a)(6) of the Bankruptcy Code, the Restated Certificates of Incorporation will prohibit the issuance of non-voting equity securities. After the Effective Date, the Reorganized Debtors may amend and restate their respective Restated Certificates of Incorporation and Restated Bylaws and other constituent documents as permitted by the laws of their respective states, provinces or countries of organization and their respective Restated Certificates of Incorporation and Restated Bylaws. The Restated Certificate of Incorporation of Reorganized Delta will, among other things, authorize the New Common Stock and, at the Supporting Noteholders’ discretion and with the Supporting Noteholders’ unanimous consent, contain restrictions on the transfer of the New Common Stock to minimize the likelihood of any potential adverse federal income tax consequences resulting from an ownership change (as defined in section 382 of the Tax Code) in Reorganized Delta. The restrictions will remain in effect until either (a) the board of directors of Reorganized Delta (with the approval of at least 66 2/3% of the shareholders of Reorganized Delta) (as set forth in the Restated Certificate of Incorporation) determines that (i) the “382(l)(5) Exception” (as described below in Section XII.B.2.b of the Disclosure Statement) is not available or not in the best interests of the Company, its affiliates and its shareholders, (ii) an ownership change (as defined in Section 382 of the Tax Code) would not substantially limit Reorganized Delta (or its direct or indirect subsidiaries) ability to use otherwise available tax attributes, or (iii) no significant value attributable to the tax attributes would be preserved from maintaining the transfer restrictions, or (b) such other date determined by the board of directors of Reorganized Delta, and approved by at least 66 2/3% of the shareholders of Reorganized Delta. While in effect, the restrictions will prevent any person who is not a 5% or greater shareholder of Reorganized Delta (a “ 5% Shareholder ” ) at the Effective Date from acquiring sufficient shares to become a 5% Shareholder, unless such person obtains the permission of the board of directors

24

of Reorganized Delta. All 5% Shareholders of Reorganized Delta at the Effective Date shall be permitted to acquire or dispose of shares of Reorganized Delta so long as, in the aggregate, Reorganized Delta does not undergo an “owner shift” (as that term is defined in section 382 of the Tax Code and the Treasury Regulations thereunder) of greater than 33% (as adjusted by the board of directors of Reorganized Delta from time to time to reflect transactions undertaken by Reorganized Delta) (the “ Permitted Owner Shift ” ) in any “testing period” (as that term is defined in section 382 of the Tax Code and the Treasury Regulations thereunder). Each 5% Shareholder at the Effective Date shall not be permitted to cause a greater “owner shift” in any “testing period” than the product of (i) the Permitted Owner Shift and (ii) a fraction equal to such 5% Shareholder’s ownership as of the Effective Date divided by the aggregate ownership of all 5% Shareholders as of the Effective Date (such product, the “ Owner Shift Limit ” ). For any transaction occurring between 5% Shareholders, any resulting “owner shift” shall be allocated equally to each such 5% Shareholder’s Owner Shift Limit. All transfers in violation of the transfer restrictions contained in Reorganized Delta’s certificate of incorporation shall be void ab initio . Any material modification to the originally filed Restated Certificate of Incorporation or Restated Bylaws of Reorganized Delta after the Confirmation Date but prior to the Effective Date may become effective; provided , however that any such modification must be approved by the Supporting Noteholders and the Creditors’ Committee (which approval shall not be withheld unreasonably).

(c) Directors and Officers of the Reorganized Debtors and Reorganized Delta . As of the Effective Date, the term of the current members of the board of directors of the Debtors shall expire, and the New Boards, including the New Delta Board and the New Subsidiary Boards, as well as the officers of each of the Reorganized Debtors shall be appointed in accordance with the Restated Certificates of Incorporation and Restated Bylaws of each Reorganized Debtor. On the Effective Date, the New Delta Board shall consist of five directors. The initial New Delta Board shall be selected as follows: two Directors shall be selected by Whitebox, two Directors shall be selected by ZCOF, and one Director shall be an independent Director jointly selected by unanimous consent of Whitebox, ZCOF and Waterstone Capital Management, L.P., provided that if non-Noteholder shareholders own 20% or more of the New Common Stock of Reorganized Delta, then a sixth Director shall be selected by the non-Noteholder shareholders. Reorganized Delta’s formation documents shall contain provisions for tie-breaking in the event there are an even number of board members. Pursuant to section 1129(a)(5) of the Bankruptcy Code, the Debtors will disclose the identity and affiliations of any Person proposed to serve on the initial New Delta Board and the New Subsidiary Boards, as well as those Persons that serve as an officer of any of the Reorganized Debtors in a Plan Supplement. To the extent any such director or officer is an “insider” under the Bankruptcy Code, the nature of any compensation to be paid to such director or officer will also be disclosed. Each such director and officer shall serve from and after the Effective Date pursuant to the terms of the Restated Certificates of Incorporation, Restated Bylaws and other constituent documents of the Reorganized Debtors.

6.2. The Joint Venture Company . On the Effective Date, Reorganized Delta and the Plan Sponsor shall amend the organizational documents of the Joint Venture Company in accordance with the terms of the Joint Venture Company LLC Agreement, the Contribution Agreement, and the Management Services Agreement. Drafts of the Limited Liability Company Agreement, Contribution Agreement, and the Management Services Agreement are attached hereto as Plan Exhibits 2, 1 and 3 , respectively.

(a) The Joint Venture Company LLC Agreement . Pursuant to the Joint Venture Company LLC Agreement, the Joint Venture Company will serve as an operating company owning the oil and gas, surface real estate and related assets formerly owned by each of Delta and the Plan Sponsor in Garfield and Mesa Counties, Colorado. Upon the execution of the Joint Venture Company LLC Agreement, there shall be 1,000,000 authorized membership units and 500,000 issued units. The Plan Sponsor shall own 333,333 (66.66%) and Reorganized Delta shall own 166,667 (33.34%) of the issued units. Each member shall have one vote for each unit that it holds in all matters subject to a vote, and the affirmative act of the members shall require the vote of at least 51% of the outstanding units. The Joint Venture Company LLC Agreement provides for corporate governance of the Joint Venture Company through the Manager and Board of Managers. The initial Manager shall be the Plan Sponsor. The Manager’s duties are set forth in the Management Services Agreement. The Manager shall serve at the pleasure of the Board of Managers, composed of six representatives; four appointed by the Plan Sponsor and two appointed by Reorganized Delta. For all actions taken by members, the member must act through the Board of Managers. Board of Managers decisions shall be binding on the Manager and the Joint Venture Company. The Board of Managers shall have a duty of good faith to the Joint Venture Company but shall owe no other fiduciary duties to the Joint Venture Company.

6.8. Cancellation of Agreements. On the Effective Date, the DIP Facility and the Indentures shall be canceled and shall be of no further force and effect except as to obligations between parties other than the Debtors and their Affiliates and Subsidiaries. The rights of the Indenture Trustee as trustee, paying agent and registrar, including but not limited to, any rights to payment of fees, expenses and indemnification obligations and liens securing such rights to payment including, but not limited to, from or on property distributed under this Plan to the Indenture Trustee, shall survive notwithstanding the cancellation of the Indentures. After the performance by the Indenture Trustee and its representatives, including without limitation its professionals, of any duties that are required under the Plan, the Confirmation Order and the Indentures, the Indenture Trustee and its representatives shall be relieved of and released from all obligations arising under the Indentures.

6.9. Surrender of Existing Securities . Each Holder of a Noteholder Claim shall surrender its note(s) to the Indenture Trustee or in the event such note(s) are held in the name of, or by a nominee of, The Depository Trust Company, the Reorganized Debtors shall seek the cooperation of The Depository Trust Company to provide appropriate instructions to the Indenture Trustee. Each Holder of a Noteholder Claim shall send its note(s) to the Indenture Trustee or The Depository Trust Company shall provide appropriate instructions to the Indenture Trustee, or the loss, theft or destruction of such note shall be established to the reasonable satisfaction of the Indenture Trustee as applicable, which satisfaction may require such Holder to submit (a) a lost instrument affidavit and (b) an indemnity bond holding the Debtors, the Reorganized Debtors, and the Indenture Trustee harmless in respect of such note and any

30

distributions made on account thereof. Upon compliance with this Section 6.8 by a Holder of any Note, such Holder shall, for all purposes under this Plan, be deemed to have surrendered such note. All property in respect of such forfeited distributions, including interest thereon, shall be promptly returned to the Reorganized Debtors by the Indenture Trustee and any such security shall be canceled.

6.10. Cancellation of the Notes and Equity Interests . On the Effective Date, except to the extent otherwise provided in this Plan, all notes, instruments, certificates and other documents evidencing (a) the 3 3/4% Notes, (b) the 7% Notes and (c) the Equity Interests shall be canceled (except as provided in Section 4.13 of this Plan), and the obligations of the Debtors thereunder and in any way related thereto shall be fully satisfied, released and discharged; provided , however , that such cancellation shall not itself alter the obligations or rights of any third parties (apart from the Debtors, their Affiliates and Subsidiaries, the Reorganized Debtors, and the Joint Venture Company). With respect to the Notes, on the Effective Date, except to the extent otherwise provided in this Plan, the Indentures and any similar agreements, including, without limitation, any related note, guaranty or similar instrument of the Debtors shall be deemed to be canceled, as permitted by section 1123(a)(5)(F) of the Bankruptcy Code, and discharged (i) with respect to all obligations owed by the Debtors under any such agreement and (ii) except to the extent provided herein below, with respect to the respective rights and obligations of the Indenture Trustee under the Indentures against the Holders of Noteholder Claims. Solely for the purpose of clause (ii) in the immediately preceding sentence, only the following rights of the Indenture Trustee shall remain in effect after the Effective Date: (A) rights as trustee, paying agent and registrar, including but not limited to any rights to payment of fees, expenses and indemnification obligations and liens securing such rights to payment including, but not limited to, from or on property distributed under this Plan to the Indenture Trustee (but excluding any other property of the Debtors, the Reorganized Debtors or their Estates), (B) rights relating to distributions to be made to the Holders of the 3 3/4% Notes or the 7% Notes by the Indenture Trustee from any source, including, but not limited to, distributions under this Plan including, without limitation, any Liens on distributions to the Holders that may be provided to the Indenture Trustee pursuant to the Indentures (but excluding any other property of the Debtors, the Reorganized Debtors or their Estates), (C) rights relating to representation of the interests of the Holders of the 3 3/4% Notes or the 7% Notes by the Indenture Trustee in the Chapter 11 Cases to the extent not discharged or released by this Plan or any order of the Bankruptcy Court and (D) rights relating to participation by the Indenture Trustee in proceedings and appeals related to this Plan.

For the avoidance of doubt, after the performance by the Indenture Trustee and its representatives, including without limitation its professionals, of any duties that are required under the Plan, the Confirmation Order and the Indentures, the Indenture Trustee and its representatives shall be relieved of and released from all obligations arising under the Indentures. The rights of the Indenture Trustee as trustee, paying agent and registrar, including but not limited to, any rights to payment of fees, expenses and indemnification obligations and liens securing such rights to payment including, but not limited to, from or on property distributed under this Plan to the Indenture Trustee, shall survive notwithstanding the cancellation of the Indentures.

6.12. Compromise of Controversies . In consideration for the distributions and other benefits provided under this Plan, the provisions of this Plan constitute a good faith compromise and settlement of all Claims and controversies resolved under this Plan and the entry of the Confirmation Order shall constitute the Bankruptcy Court’s approval of such compromises and settlements under Bankruptcy Rule 9019.

6.13. Restructuring Transactions . On or prior to the Effective Date, any Debtor and, after the Effective Date, any Reorganized Debtor, may enter into or undertake any Restructuring Transactions and may take such actions as may be determined by such Debtor or Reorganized Debtor to be necessary or appropriate to effect such Restructuring Transactions. The actions to effect the Restructuring Transactions may include, without limitation: (i) the execution and delivery of appropriate agreements or other documents of merger, consolidation, conversion, restructuring, recapitalization, disposition, liquidation or dissolution containing terms that are consistent with the terms herein and that satisfy the requirements of applicable law and such other terms to which the applicable entities may agree; (ii) the execution and delivery of appropriate instruments of transfer, assignment, assumption, disposition, or delegation of any asset, property, right, liability, duty or obligation on terms consistent with the terms herein and having such other terms to which the applicable entities may agree; (iii) the filing of appropriate certificates or articles of merger, consolidation, conversion or dissolution (or similar instrument) pursuant to applicable law; and (iv) all other actions which the applicable entities may determine to be necessary or appropriate, including making filings or recordings that may be required by applicable law in connection with such transactions.

In each case in which the surviving, resulting or acquiring person in any such Restructuring Transaction is a successor to a Debtor or Reorganized Debtor, such surviving, resulting or acquiring person will perform the obligations of the applicable Debtor or Reorganized Debtor pursuant to this Plan to pay or otherwise satisfy the Allowed Claims against such Debtor or Reorganized Debtor, except as provided in any contract, instrument or other agreement or document effecting a disposition to such surviving, resulting or acquiring person, which may provide that another Debtor or Reorganized Debtor will perform such obligations. Implementation of the Restructuring Transactions shall not affect any distributions, discharges, exculpations, releases or injunctions set forth in this Plan.

The Restructuring Transactions shall be authorized and approved by the Confirmation Order pursuant to, among other provisions, sections 1123 and 1141 of the

32

Bankruptcy Code and section 303 of title 8 of the Delaware Code, if applicable, without any further notice, action, third-party consents, court order or process of any kind, except as otherwise set forth herein or in the Confirmation Order.

ARTICLE VII

PROVISIONS GOVERNING DISTRIBUTIONS;

TREATMENT OF DISPUTED CLAIMS

7.1. Date of Distributions on Account of Allowed Claims . Unless otherwise provided herein, any distributions and deliveries to be made under this Plan shall be made on the Effective Date or as soon as practicable thereafter. In the event that any payment or act under this Plan is required to be made or performed on a date that is not a Business Day, then the making of such payment or the performance of such act may be completed on the next succeeding Business Day, but shall be deemed to have been completed as of the required date.

7.2. Sources of Cash for Plan Distribution . Except as otherwise provided in this Plan or Confirmation Order, all Cash required for the payments to be made hereunder to Delta’s prepetition and administrative creditors shall be obtained from the Cash proceeds drawn from the JV Company Credit Facility, the Exit Loan and Delta and Reorganized Delta’s operations and Cash on hand, and all Cash required for the payments to be made hereunder to the prepetition and administrative creditors of all Debtors other than Delta shall be obtained from the Cash proceeds available in such Debtor’s Estate, all as set forth in the flow of funds memorandum agreed upon by the Debtors, the Creditors’ Committee (which agreement shall not be withheld unreasonably) and the Supporting Noteholders, a form of which shall be filed as a Plan Supplement.

7.3. Time Bar to Cash Payments. Checks issued in respect of Allowed Claims shall be null and void if not negotiated within one hundred eighty (180) days after the date of issuance thereof. Requests for reissuance of any voided check shall be made directly to the Disbursement Agent by the Holder of the Allowed Claim to whom such check was originally issued. Any Claim in respect of such a voided check shall be made on or before the first anniversary of the date on which such distribution or payment was made. If no Claim is made as provided in the preceding sentence, all Claims in respect of voided checks shall be discharged and forever barred and such unclaimed distributions shall revert to the Reorganized Debtors, notwithstanding any federal or state escheat laws to the contrary.

33

7.4. Disbursement Agent . The Disbursement Agent, or such other Person designated by the Recovery Trustee as Disbursement Agent, shall make all distributions under this Plan on the Effective Date. A Disbursement Agent shall not be required to give any bond or surety or other security for the performance of its duties unless otherwise ordered by the Bankruptcy Court.

7.5. Record Date for Distribution . Except as otherwise required to comply with the provisions of the Claims Trading Order, distributions shall only be made to the record Holders of Allowed Claims as of the Confirmation Date. On the Confirmation Date, at the close of business for the relevant register, all registers maintained by the Debtors and the Reorganized Debtors, and each of their respective agents, successors and assigns, shall be deemed closed for purposes of determining whether a Holder of such a Claim is a record Holder entitled to distributions under this Plan. The Debtors and the Reorganized Debtors, and all of their respective agents, successors and assigns shall have no obligation to recognize, for purposes of distributions pursuant to or in any way arising from this Plan (or for any other purpose), any Claims that are transferred after the Confirmation Date. Instead, they shall be entitled to recognize only those record Holders set forth in the registers as of the Confirmation Date, irrespective of the number of distributions made under this Plan or the date of such distributions. Furthermore, if a Claim is transferred twenty (20) or fewer calendar days before the Confirmation Date, the Disbursement Agent shall make distributions to the transferee only if the transfer form or other appropriate writing contains an unconditional and explicit certification and waiver of any objection to the transfer by the transferor. Notwithstanding anything in this Section 7.5 to the contrary, (i) distributions to Holders of Allowed Claims under section 502(h) of the Bankruptcy Code shall be made to the Holder of such Claim after a Final Order has been entered by the Court that deems such Claim as Allowed and (ii) distributions may be made to Holders of Allowed Claims who acquired their Claims after the Confirmation Date pursuant to the “Sell-Down Procedures” set forth in the Claims Trading Order.

If any dispute arises as to the identity of a Holder of an Allowed Claim that is entitled to receive a distribution pursuant to this Plan, the Disbursement Agent or the servicers, as applicable, may, in lieu of making such distribution to such Person, make the distribution into an escrow account until the disposition thereof is determined by Final Order or by written agreement among the interested parties to such dispute.

7.6. Delivery of Distributions . Subject to Bankruptcy Rule 9010, all distributions to Holders of Allowed Claims shall be made at the address of such Holder as set forth in the books and records of the Debtors as of the Record Date. In the event that any distribution to any Holder is returned as undeliverable, the Disbursement Agent shall use reasonable efforts to determine the current address of such Holder, but no distribution to such Holder shall be made unless and until the Disbursement Agent has determined the then current address of such Holder, at which time such distribution shall be made to such Holder without interest; provided , however , that such distributions shall be deemed unclaimed property under section 347(b) of the Bankruptcy Code at the expiration of one year from the Effective Date. After such date, all unclaimed property or interest in property shall revert to the Reorganized Debtors and the Claim of any other Holder to such property or interest in property shall be discharged and forever barred notwithstanding any applicable federal or state escheat, abandoned or unclaimed property laws to the contrary.

34

7.7. Objections to and Estimations of Claims; Resolution of Disputed Claims.

(a) On and after the Effective Date, the Recovery Trustee, the Reorganized Debtors and any creditor, may continue to attempt to consensually resolve any disputes regarding the amount of any Claim and shall have the right, but not the obligations, to object to the allowance of any Claim and may file with the Court any other appropriate motion or adversary proceeding with respect thereto. All such objections may be litigated to Final Order. The Recovery Trustee shall retain the rights and defenses the Debtors or their Estates had with respect to any Claim or Equity Interest immediately prior to the Effective Date, subject to the provisions of this Plan.

(b) All objections to Claims shall be filed with the Bankruptcy Court by the Claims Objection Deadline in accordance with its local rules, and a copy of the objection must be served on the Holder of the subject Claim before the expiration of the Claims Objection Deadline; otherwise such Claims shall be deemed Allowed in accordance with section 502 of the Bankruptcy Code. The objection shall notify the Holder of the subject Claim of the deadline for responding to such objection. The Claims Objection Deadline can be extended up to an additional ninety (90) days by the Recovery Trustee filing a notice with the Court and thereafter as permitted by order of the Bankruptcy Court, upon notice and a hearing.

(c) Within thirty (30) days after service of an objection, the Holder whose Claim was objected to must, in accordance with the local rules of the Bankruptcy Court, serve and file a written response to the objection with the Bankruptcy Court and serve a copy on the Disbursement Agent, the Recovery Trustee, the Reorganized Debtors, any objecting creditor and the notice parties for the Debtors and the Supporting Noteholders identified in section 12.18 of this Plan. Failure to serve and file a written response within the thirty (30) day time period may result in the Bankruptcy Court granting the relief demanded in the Claim objection without further notice or hearing.

(d) Before the Effective Date, the Debtors or any objecting creditors may (but are not required to) at any time request that the Bankruptcy Court estimate any Disputed Claim pursuant to § 502(c) of the Bankruptcy Code, that is contingent or unliquidated or any Disputed Claim arising from a right to an equitable remedy or breach of performance for any reason, regardless of whether any party previously has objected to such Claim or whether the Bankruptcy Court has ruled on any such objection. From and after the Effective Date, the Recovery Trustee, the Reorganized Debtors or any objecting creditor may (but are not required to) at any time request that the Bankruptcy Court estimate any Disputed Claim pursuant to § 502(c) of the Bankruptcy Code, that is contingent or unliquidated or any Disputed Claim arising from a right to an equitable remedy or breach of performance for any reason, regardless of whether any party previously has objected to such Claim or whether the Bankruptcy Court has ruled on any such objection. With respect to any request for estimation, the Bankruptcy Court shall retain jurisdiction to estimate any such Claim at any time, including during the litigation of any objection to any Claim or during the pendency of any appeal relating to such objection. Notwithstanding any provision otherwise in this Plan, a Claim that has been expunged from the Claims Register, but that either is subject to appeal or has not been the subject of a Final Order, shall be deemed to be estimated for distribution purposes at zero ($0) dollars, unless otherwise

35

ordered by the Bankruptcy Court. In the event that the Bankruptcy Court estimates any contingent or unliquidated Claim, that estimated amount shall constitute a maximum limitation on such Claim for all purposes under this Plan (including for purposes of distributions), and the relevant party may elect to pursue any supplemental proceedings to object to any distribution under this Plan on such Claim. All of the aforementioned objection, estimation and resolution procedures are intended to be cumulative and not exclusive of one another. Claims may be estimated and subsequently compromised, settled, withdrawn, recharacterized or resolved by any mechanism approved by the Bankruptcy Court.

(e) The Debtors, the Disbursement Agent or the Recovery Trustee , as applicable, may set off against any Claim, and the payments made pursuant to this Plan in respect of such Claim, any claims of any nature whatsoever that any of the Debtors or the Recovery Trustee (as assignee of such claims) may have against the Holder of the Claim, but neither the failure to do so nor the allowance of such Claim shall constitute a waiver or release by the Debtors or the Recovery Trustee of any claims or rights against the Holder of the Claim; provided , however , that any claimant shall have the right to object to any such setoff made by the Debtors. Any payment in respect of a disputed, unliquidated, or contingent Claim shall be returned promptly to the Disbursement Agent in the event and to the extent such Claims are determined by the Bankruptcy Court or any other court of competent jurisdiction not to be Allowed Claims.

(f) Notwithstanding any other provision of this Plan and except as otherwise agreed by the relevant parties, the Disbursement Agent shall not be required to make any partial payments or partial distributions to a Person, estate or trust with respect to a Disputed Claim until all such disputes in connection with such Disputed Claim have been resolved by settlement or Final Order. To the extent that there is any Holder of a Claim that is the subject of a Cause of Action, the Disbursement Agent shall have the authority to withhold any distribution to such Holder of a Claim until such Cause of Action is subject to final nonappealable order or otherwise is settled or adjudicated in the Bankruptcy Court.

(g) The holder of a Disputed Claim is not entitled to recover unless a Disputed Claim becomes an Allowed Claim and in such event any Holder of a Disputed Claim may only be entitled to receive a distribution on its Allowed Claim from the Disputed Claim Reserve.

(h) The Disbursement Agent shall establish and maintain the Disputed Claim Reserve as a separate reserve in order to satisfy Disputed Claims upon the resolution of such claims. Property of the Estate deposited into the Disputed Claim Reserve shall be distributed to the holders of Disputed Claims when such Disputed Claims become Allowed Claims. Any funds remaining in the Disputed Claim Reserve after all Disputed Claims are resolved shall be transferred to Reorganized Delta.

7.8. Noteholder Claims and DIP Facility Claims . (a) The Indenture Trustee shall be deemed to be the Holder of all Noteholder Claims, for purposes of distributions to be made hereunder, and all distributions on account of such notes shall be made to or at the direction of the Indenture Trustee. The Indenture Trustee shall hold or direct such distributions for the benefit of the Holders of Allowed Noteholder Claims. As soon as practicable following compliance with the requirements set forth in Section 6.9 of this Plan, the Indenture Trustee shall

7.11. Fractional Shares . No fractional shares of New Common Stock shall be distributed and no Cash shall be distributed in lieu of such fractional shares.

7.13. Exemption from Securities Law . The issuance of the New Common Stock and any other securities issued pursuant to this Plan and any subsequent sales, resales or transfers, or other distributions of any such securities shall be exempt from any federal or state securities laws registration requirements to the fullest extent permitted by section 1145 of the Bankruptcy Code.

7.15. No Postpetition Interest on Claims . Unless otherwise specifically provided for in this Plan or the Confirmation Order, or required by applicable bankruptcy law, to the extent a Claim is not paid in full on the Effective Date, postpetition interest shall not accrue or be paid on any Claims, and no Holder of a Claim shall be entitled to interest accruing on or after the Petition Date on such Claim. For the avoidance of doubt, Administrative Claims of tax authorities (including any Administrative Claims of the Internal Revenue Service for any federal taxes, which shall accrue interest at the rate and in the manner established under 26 U.S.C. §§ 6621 and 6622), shall accrue interest at the rate and in the manner specified by the applicable tax regulation.

43

Parties, if any, and (c) the commencement of such litigation against the ZCOF Parties has been approved in advance by a majority of the Wapiti Trust Oversight Board, which majority shall include the vote of Whitebox, provided that to the extent Whitebox votes against the commencement of such litigation against the ZCOF Parties and the Recovery Trustee disagrees with such determination, then the Recovery Trustee is hereby authorized to file a motion with the Bankruptcy Court seeking a finding that such determination not to pursue the litigation against the ZCOF Parties was not reasonable and upon such a finding, the Bankruptcy Court shall order the Wapiti Trust to pursue such litigation against the ZCOF Parties; provided further , however , that the ZCOF Parties reserve all rights and defenses, at law and in equity to defend against any and all actions and no release of any party provided for herein shall prejudice the ZCOF Parties’ rights or defenses. Such release, waiver and discharge shall not operate as a release, waiver or discharge of any Released Party in respect of any express contractual obligation of any such party effective from and after the Effective Date, provided that no Person who votes to reject this Plan will receive the benefit of a release.

10.8. Consensual Releases By Holders of Claims . Except for the right to enforce this Plan, each Holder of a Claim who affirmatively votes to accept this Plan and does not indicate its preference to opt-out of the releases contained in this Section 10.8 on its ballot shall for good and adequate consideration, be deemed to forever release, waive and discharge the Released Parties, to the fullest extent permitted by applicable law, of and from any and all Claims, demands, causes of action and the like, existing as of the Effective Date or thereafter arising from any act, omission, event, or other occurrence that occurred on or prior to the Effective Date, whether direct or derivative, liquidated or unliquidated, fixed or contingent, matured or unmatured, disputed or undisputed, known or unknown, foreseen or unforeseen, at law, in equity or otherwise that is based on, relates to, or in any manner arises from, in whole or in part, the Debtors, the Debtors’ restructuring, the Chapter 11 Cases, the purchase, sale or rescission of the purchase or sale of any security of the Debtors, the subject matter of, or the transactions or events giving rise to, any Claim that is treated in this Plan, the business or contractual arrangements between the Debtors and any Released Party relating to the restructuring of Claims prior to or in the Chapter 11 Cases or the negotiation, formulation or preparation of this Plan, or any related agreements, instruments or other documents (except for any liability that results from bad faith, willful misconduct or gross negligence as determined by a Final Order). Holders of Claims not voting to accept this Plan are not granting the releases contained in this Section 10.8. For the avoidance of doubt, to the extent the Holder of a Claim in a voting Class votes to accept this Plan with respect to that Claim and does not opt-out of the releases under section 10.8 of this Plan, and such Holder also holds a Claim in a non-voting Class, any release granted as a result of such Holder’s vote with respect to its voting Class Claim shall not be deemed a release of such Holder’s non-voting Class Claim. Notwithstanding the foregoing, in the event that this Plan is not confirmed, no party shall be deemed to have released or shall release any claims or be released hereby. Furthermore, notwithstanding the foregoing, such release, waiver and discharge shall not operate as a release, waiver or discharge of any Released Party in respect of any express contractual obligation of any such Released Party incurred in connection with this Plan or of any express contractual obligation of any non-Debtor party due to any other non-Debtor party.

10.9. Abrogation of Successor Liability . To the extent permitted pursuant to applicable law, the transfer of property of the Debtors to the Joint Venture Company, the

10.15. No Acquisition of a Majority of Voting Interests.

Notwithstanding any such holding, alteration or interpretation, the remaining terms and provisions of this Plan shall remain in full force and effect and shall in no way be affected, impaired or invalidated by such holding, alteration or interpretation.

12.16. No Admissions . If the Effective Date does not occur, this Plan shall be null and void in all respects, and nothing contained in this Plan shall (a) constitute a waiver or release of any Claims by or against, or any Equity Interests in, the Debtors, (b) prejudice in any manner the rights of the Debtors or any other party in interest or (c) constitute an admission of any sort by the Debtors or other party in interest.

12.17. Reservation of Rights. Except as expressly set forth herein, this Plan shall have no force and effect unless and until the Bankruptcy Court has entered the Confirmation Order and the Effective Date has occurred. The filing of this Plan, any statement or provision contained in this Plan, or the taking of any action by the Debtors or any other party with respect to this Plan shall not be and shall not be deemed to be an admission or waiver of any rights of the Debtors or any other party with respect to Claims or Equity Interests or any other matter.
