Exhibit 99.1

IN THE UNITED STATES BANKRUPTCY COURT

FOR THE DISTRICT OF DELAWARE

FINAL ORDER ESTABLISHING NOTIFICATION AND HEARING PROCEDURES

FOR TRADING IN EQUITY SECURITIES

Upon consideration of the motion (the “Motion”)² of the Debtors for entry of an order (the “Final Order”) (i) establishing notice and hearing procedures that must be satisfied before certain transfers of common stock of Delta Petroleum Corporation and Amber Resources Company of Colorado or any beneficial interest therein (the “Stock”) are deemed effective; and (ii) allowing for a hearing with respect to the prospective application of such procedures if any official committee of unsecured creditors appointed in these cases (the “Creditors’ Committee”) raises a timely objection; and it appearing that the relief requested is in the best interests of the Debtors’ estates, their creditors, and other parties in interest; and upon consideration of the Young Declaration; and it appearing that this Court has jurisdiction over this matter pursuant to 28 U.S.C. §§ 157 and 1334; and it appearing that this Motion is a core proceeding pursuant to 28 U.S.C. § 157; and adequate notice of the Motion and opportunity for objection having been given; and it appearing that no other notice need be given; and after due deliberation and sufficient cause therefore;

IT IS HEREBY ORDERED THAT:

1. The Motion is GRANTED, as set forth herein.

2. Any purchase, sale, or other transfer of Stock in violation of any of the Procedures set forth herein shall be null and void ab initio as an act in violation of the automatic stay under sections 362 and 105(a) of the Bankruptcy Code.

3. The following procedures shall apply to trading in Stock:

(a) Any person or entity (as defined in Treasury Regulations section 1.382-3(a) for purposes of this these Procedures) who currently is or becomes a Substantial Shareholder (as defined in paragraph (e) below) shall file with this Court, and serve on counsel to the Debtors, a notice of such status, in the form attached to this Final Order as Exhibit “1”, on or before the later of (i) twenty calendar days after the effective date of the notice of entry of this Final Order or (ii) ten calendar days after becoming a Substantial Shareholder.

(b) At least thirty calendar days before effectuating any transfer of equity securities (including Options to acquire such securities, as defined below) that would result in an increase in the amount of Stock beneficially owned by a Substantial Shareholder or would result in a person or entity becoming a Substantial Shareholder, such Substantial Shareholder shall file with this Court, and serve on counsel to the Debtors, advance written notice, in the form attached to this Final Order as Exhibit “2”, of the intended transfer of equity securities.

(c) At least thirty calendar days before effectuating any transfer of equity securities (including Options to acquire such securities) that would result in a decrease in the amount of Stock beneficially owned by a Substantial Shareholder or would result in a person or entity ceasing to be a Substantial Shareholder, such Substantial Shareholder shall file with this Court, and serve on counsel to the Debtors, advance written notice, in the form attached to this Final Order as Exhibit “3”, of the intended transfer of equity securities (the notices required to be filed and served under paragraph (b) and this paragraph (c), each a “Notice of Proposed Transfer”).

(d) The Debtors shall have thirty calendar days after receipt of a Notice of Proposed Transfer to file with this Court and serve on such Substantial Shareholder an objection to any proposed transfer of equity securities described in the Notice of Proposed Transfer on the grounds that such transfer may adversely affect the Debtors’ ability to utilize their Tax Attributes. If the Debtors file an objection, such transaction will not be effective unless approved by a final and nonappealable order of this Court. If the Debtors do not object within such 30-day period, such transaction may proceed solely as set forth in the Notice of Proposed Transfer. Further transactions within the scope of this paragraph must be the subject of additional notices as set forth herein, with an additional 30-day waiting period.

2

(e) For purposes of this these Procedures, (i) a “Substantial Shareholder” is any person or entity which beneficially owns at least 1,371,332 shares in Delta Petroleum Corporation or at least 221,644 shares in Amber Resources Company of Colorado (representing, respectively, approximately 4.75% of all issued and outstanding shares) of Stock, and (ii) “beneficial ownership” (or any variation thereof of Stock and Options to acquire Stock) shall be determined in accordance with applicable rules under Section 382, Treasury Regulations promulgated thereunder, and rulings issued by the Internal Revenue Service, and thus, to the extent provided therein, from time to time shall include, without limitation, (x) direct and indirect ownership (e.g., a holding company would be considered to beneficially own all shares owned or acquired by its subsidiaries), (y) ownership by such holder’s family members and persons acting in concert with such holder (pursuant to a formal or informal understanding) to make a coordinated acquisition of stock, and (z) an Option (as defined below) to acquire Stock. An “Option” to acquire stock includes all interests described in Treasury Regulation section 1.382-4(d)(9), including any contingent purchase, warrant, convertible debt, put, stock subject to risk of forfeiture, contract to acquire stock, or similar interest, regardless of whether it is contingent or otherwise not currently exercisable. For the avoidance of doubt, by operation of the definition of beneficial ownership in clause (ii) of this paragraph, an owner of an Option to acquire Stock may be treated as the owner of such Stock.

(f) The Debtors, their counsel, counsel for Lender, and counsel for the Creditors’ Committee shall keep all information provided in any notices delivered pursuant to the Procedures strictly confidential and shall not disclose the contents thereof to any person (including any member of the Creditors’ Committee), except (i) to the extent necessary to respond to a petition or objection filed with the Court, (ii) to the extent otherwise required by law, or (iii) to the extent that the information contained therein is already available to the public; provided, however, that the Debtors may disclose the contents thereof to their financial advisors, who shall keep all such notices strictly confidential in the same manner as the Debtors are required to do so, subject to further Court order. To the extent confidential information is necessary to respond to a petition or objection filed with the Court, such confidential information shall be filed under seal or in redacted form.

(g) Any purchase, sale, or other transfer of Stock in violation of any of the Procedures set forth herein shall be null and void ab initio as an act in violation of the automatic stay under sections 362 and 105(a) of the Bankruptcy Code.

4. The Debtors alone (if no Creditors’ Committee has been appointed), with the consent of the Creditors’ Committee (if a Creditors’ Committee has been appointed) or pursuant to order of this Court may waive, in writing, any and all restrictions, stays, and notification procedures contained in this Final Order; provided, however, that any such waiver shall be filed with this Court.

3

5. Any notice required by this Final Order to be served by Substantial Shareholders, if effected prior to the filing of a proof of claim by a Substantial Shareholder, will not limit the right of a creditor to assert any and all claims, whether or not such claims are in addition to or differ from those listed on the notice, in a proof of claim filed in accordance with any future orders of this Court.

6. The Debtors shall serve the Notice of Order setting forth the procedures authorized herein substantially in the form annexed to the Motion as Exhibit “B” on: (a) the Office of the United States Trustee for the District of Delaware; (b) counsel for Macquarie Bank Limited, the administrative agent under the Debtors’ pre-petition secured credit facility; (c) counsel to Whitebox Advisors LLC, the proposed DIP Lender to the Debtors; (d) those parties listed on the list of creditors holding the thirty (30) largest unsecured claims against the Debtors (on a consolidated basis), as identified in their chapter 11 petitions, (e) the Securities and Exchange Commission; (f) the Internal Revenue Service; (g) local taxing authorities; (h) any statutory committee appointed under section 1102 of the Bankruptcy Code; (i) the transfer agents for any Stock; and (j) all parties that have requested notice in these chapter 11 cases. Notice served pursuant to the preceding sentence shall be via first class mail, postage prepaid. The Debtors shall also file a copy of this Order as an exhibit to a report on Form 8-K filed with the Securities and Exchange Commission. No further notice of entry of this Order need be served by the Debtors.

7. Any transfer agent(s) for any Stock having notice hereof shall provide such Notice of Order to all holders of such Stock in excess of 500,000 shares in Delta Petroleum Corporation or 100,000 shares in Amber Resources Company of Colorado registered with such transfer; provided, that, if any transfer agent provides the Debtors with the name and addresses

4

of all holders of such Stock, the Debtors shall deliver the Notice of Order to such holders. Any such registered holder must, in turn, provide such Notice of Order to any holder for whose account such registered holder holds such Stock in excess of 500,000 shares in Delta Petroleum Corporation or 100,000 shares in Amber Resources Company of Colorado, and so on down the chain of ownership.

8. Any person or entity or broker or agent acting on such person or entity’s behalf who sells an aggregate amount of at least 500,000 shares in Delta Petroleum Corporation or 100,000 shares in Amber Resources Company of Colorado (or an Option with respect thereto) to another person or entity shall provide a copy of the Notice of Order to such purchaser of such Stock or to any broker or agent acting on such purchaser’s behalf.

9. Nothing herein shall preclude any person or entity that desires to purchase or transfer any stock or from requesting relief from this Final Order in this Court subject to the Debtors’ rights to oppose such relief.

10. The requirements set forth in this Order are in addition to the requirements of Rule 3001(e) of the Federal Rules of Bankruptcy Procedure and applicable securities, corporate, and other laws, and do not excuse compliance therewith.

11. The terms and conditions of this Order shall be immediately effective and enforceable upon its entry.

12. This Court retains jurisdiction with respect to all matters arising from or related to the implementation of this Order.
