AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) dated as of December 7, 2005, is by and among NATIONAL ENERGY GROUP, INC., a Delaware corporation (the “Company”), AREP OIL & GAS LLC, a Delaware limited liability company (“AREP Oil & Gas”), NEG IPOCO, INC., a Delaware corporation (“IPO Co.”) wholly owned by AREH (as hereafter defined), and, solely for purposes of Sections 3.2, 3.3 and 4.16 of this Agreement, AMERICAN REAL ESTATE HOLDINGS LIMITED PARTNERSHIP, a Delaware limited partnership (“AREH”). Capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in Section 7.8 of this Agreement.

WHEREAS, AREP Oil & Gas owns an aggregate of 5,597,824 shares of common stock, par value $.01 share, of the Company (the “Company Common Stock”), constituting approximately 50.1% of the total outstanding capital stock of the Company, and wishes to include the Company in a series of transactions, including a business combination and concurrent initial public offering, all as contemplated herein.

WHEREAS, the Board of Directors of the Company (the “Company Board”), based on the recommendation of a special committee thereof consisting solely of Xxxxxx X. Xxxx (the “Special Committee”), has (a) determined that the merger of the Company with and into IPO Co. (the “Merger”), with IPO Co. continuing as the surviving corporation, whereby each Share (as defined below) will, upon the terms and subject to the conditions set forth herein, be converted into the right to receive a number of fully paid and nonassessable shares of IPO Co. Common Stock (as defined below) equal to the Exchange Ratio (as defined below), is fair to, and in the best interests of, holders of such Shares (other than AREP Oil & Gas and its affiliates), and (b) approved and adopted this Agreement and the transactions contemplated hereby and declared their advisability.

WHEREAS, AREP Oil & Gas has advised the Company that (i) it is a buyer, and not a seller, as regards its interest in the Company and its affiliates and (ii) it is willing to support the Merger and has no interest in supporting, as a stockholder of the Company, a transaction for the sale of its stock, or any merger or other disposition of the Company or its assets, to a third party.

WHEREAS, the Board of Directors of AREP Oil & Gas and the Board of Directors of IPO Co. have approved this Agreement and have determined that the Agreement and the Merger are advisable and in the best interests of their respective members and stockholders, as the case may be, and AREH, as the sole stockholder of IPO Co., will, immediately following the execution hereof by the parties hereto, approve and adopt this Agreement.

WHEREAS, for Federal income tax purposes it is intended that the Merger qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

NOW, THEREFORE, in consideration of the foregoing premises and the representations, warranties, covenants and agreements herein contained, and intending to be legally bound hereby, the Company, AREP Oil & Gas and IPO Co. hereby agree as follows:

ARTICLE I

THE MERGER

Section 1.1 The Merger. At the Effective Time (as defined below) and upon the terms and subject to the conditions of this Agreement and in accordance with the Delaware General Corporation Law (the “DGCL”), the Company shall be merged with and into IPO Co. (the “Merger”). Following the Merger, IPO Co. shall continue as the surviving corporation (the “Surviving Corporation”) and the separate corporate existence of the Company shall cease. The Merger is intended to qualify as a tax free reorganization under Section 368(a) of the Code.

Section 1.2 Effective Time. Subject to the terms and conditions set forth in this Agreement, on the Closing Date (as defined in Section 1.3), the parties hereto shall (a) cause the Merger to be consummated by filing a duly executed and acknowledged Certificate of Merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware pursuant to Section 251 of the DGCL and (b) make such other filings with the Secretary of State of the State of Delaware as shall be necessary to effect the Merger. The Merger shall become effective at such time as a properly executed copy of the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware in accordance with Section 251 of the DGCL, or such later time as AREP Oil & Gas and the Company may agree upon and as may be set forth in the Certificate of Merger (the time the Merger becomes effective being referred to herein as the “Effective Time”).

Section 1.3 Closing of the Merger. The closing of the Merger (the “Closing”) will take place substantially contemporaneously with the consummation of the IPO Transaction (the “Closing Date”), at the offices of AREP Oil & Gas, located at 000 Xxxxx Xxxxxxx Xxxx, Xx. Xxxxx, XX, unless another time, date or place is agreed to in writing by the parties hereto.

Section 1.4 Effects of the Merger. The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of the Company and IPO Co. shall vest in the Surviving Corporation, and all debts, liabilities, obligations, restrictions and duties of the Company and IPO Co. shall become the debts, liabilities, obligations, restrictions and duties of the Surviving Corporation.

Section 1.5 Organizational Documents. The certificate of incorporation and bylaws of IPO Co. in effect at the Effective Time shall be the certificate of incorporation and bylaws of the Surviving Corporation until amended in accordance with Applicable Law; provided, however, that at the Effective Time, the certificate of incorporation of IPO Co. will be amended to change the name of IPO Co. to a name specified by AREP Oil & Gas. The certificate of incorporation of IPO Co. in effect at the Effective Time shall be substantially in the form attached hereto as Exhibit C.

Section 1.6 Directors, Officers, Managers, etc. The directors, officers and/or managers of IPO Co. at the Effective Time shall be the initial directors, officers and/or managers of the Surviving Corporation, each to hold office in accordance with the organizational

documents of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified.

Section 1.7 Conversion of Shares.

(a) At the Effective Time, each share of Company Common Stock (individually a “Share” and collectively the “Shares”) issued and outstanding immediately prior to the Effective Time (other than Shares held in the Company’s treasury or by any of the Company’s subsidiaries) shall, by virtue of the Merger and without any action on the part of AREP Oil & Gas, IPO Co., the Company or the holder thereof, be converted into the right to receive that fraction of a fully-paid and non-assessable share of common stock, par value $.01 per share, of IPO Co. (“IPO Co. Common Stock”) equal to the Exchange Ratio (as defined below) (the “Merger Consideration”).

(b) The “Exchange Ratio” shall be determined by multiplying 0.00000008936 [i.e., 1 / 11,190,650 (the number of outstanding Shares)] by the Share Amount (as hereafter defined). The “Share Amount” shall mean that number of shares of IPO Co. Common Stock which results in the holders of the Shares receiving, in the aggregate, a 7.990% (the “Percentage”) economic interest in the entire equity of the Enterprise (as hereafter defined) immediately prior to consummation of the IPO Transaction; provided, however, that the parties acknowledge and agree that: (i) the Percentage is based upon the assumption that the Enterprise will be subject to $500 million of net indebtedness (i.e., total indebtedness minus cash) immediately prior to or simultaneously with consummation of the IPO Transaction (after all incurrences and repayments of debt contemplated in Exhibit B hereto and excluding intercompany notes of the members of the Enterprise and their subsidiaries); (ii) to the extent that the Enterprise is subject to less than $500 million of net indebtedness at such time (after all incurrences and repayments of debt contemplated in Exhibit B hereto and excluding intercompany notes of the members of the Enterprise and their subsidiaries), the Percentage will be reduced by subtracting the Adjustment Amount (as hereafter defined) from the Percentage; and (iii) to the extent that the Enterprise is subject to in excess of $500 million of net indebtedness at such time (after all incurrences and repayments of debt contemplated in Exhibit B hereto and excluding intercompany notes of the members of the Enterprise and their subsidiaries), the Percentage will be increased by adding the Adjustment Amount to the Percentage. The “Adjustment Amount” shall mean the product of (x) 0.6322% and (y) that fraction obtained by dividing the positive difference between $500 million and the actual net indebtedness of the Enterprise immediately prior to or simultaneously with consummation of the IPO Transaction (after all incurrences and repayments of debt contemplated in Exhibit B hereto and excluding intercompany notes of the members of the Enterprise and their subsidiaries) by $100 million. Set forth on Schedule 1.7 hereto is an example of how the Percentage shall be calculated. At Closing, the remaining economic interest in the Enterprise will be held, directly or indirectly, by AREH. The term “Enterprise” shall mean a combination or consolidation of entities which includes 100% of the equity interests in each of AREP Oil & Gas, National Onshore, National Offshore and the Company.

(c) Each of the parties acknowledge and agree that the structure of the IPO Transaction and the transactions described in Exhibit B have not been determined as of the date of this Agreement but the parties will work together in good faith to ensure that, regardless of the structure of such transactions, the holders of the Shares will receive in the Merger, in the aggregate, the Percentage, it being understood that the percentage interests of such holders in the Enterprise shall be reduced as a result of the issuance of shares of IPO Co. Common Stock pursuant to the IPO Transaction. The dilution resulting from the issuance of shares of IPO Co. Common Stock pursuant to the IPO Transaction will be borne equally by all holders of the IPO Co. Common Stock prior to the IPO Transaction (based upon the number of shares held). Attached as Schedule 1.7 is an example of the proportionate economic interests based on the assumptions set forth therein.

(d) The parties acknowledge and agree that, following consummation of the IPO Transaction, there will be no restrictions or limitations, other than as imposed by applicable law, on any transactions by IPO Co., including, without limitation, any issuances of securities by IPO Co. (whether involving the issuance of shares of IPO Co. Common Stock pursuant to any employee or executive option plan or other equity incentive plan adopted by IPO Co., the issuance of shares of IPO Co. Common Stock in connection with any secondary equity offering, the issuance of shares of IPO Co. Common Stock upon conversion of any convertible equity or debt securities that IPO Co. may issue in the future, or otherwise), or any adjustment, antidilution protection or preemptive right in respect thereof. The receipt of the Percentage is only for purposes of determining the Merger Consideration and is not an ongoing obligation, and neither IPO Co. nor any other person shall have any duty to cause the Percentage to be maintained following the Merger.

(e) The parties further acknowledge and agree that: (i) the structure of the IPO Transaction may involve IPO Co. owning an equity interest in AREP Oil & Gas, with the remaining interest (the “Interest”) as of the Closing owned by AREH or affiliates of AREH which would be convertible into shares of IPO Co. Common Stock based upon AREH’s pro rata ownership in the Enterprise (subject to typical anti-dilution protections) (the “Convertible Option”) as a result of the Interest; (ii) initial capital accounts in AREP Oil & Gas will be set at fair market value; and (iii) at the formation of IPO Co., AREH will be issued a share or shares of non-redeemable Class B Common Stock of IPO Co. which will provide AREH with that percentage of the outstanding voting power of IPO Co. Common Stock equivalent to the number of shares of IPO Co. Common Stock it would obtain upon exercise of the Convertible Option; provided, however, that such Class B Common Stock shall not be entitled to any dividends or liquidation preference (other than a nominal preference not to exceed $1,000 in the aggregate) over the shares of IPO Co. Common Stock. Attached as Schedule 1.7 is an example of AREH’s conversion and voting rights.

(f) At the Effective Time, each Share held in the treasury of the Company immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of any party, be canceled, retired and cease to exist, and no shares of IPO Co. Common Stock shall be delivered with respect thereto.

(g) At the Effective Time, each share of common stock and Class B Common Stock of IPO Co. issued and outstanding immediately prior to the Effective Time shall remain outstanding.

Section 1.8 Dissenters’ Rights. In accordance with Section 262 of the DGCL, the holders of the Shares shall not be entitled to dissenters’ or appraisal rights.

Section 1.9 Exchange of Certificates.

(a) From time to time following the Effective Time, as required by subsections (b) and (c) below, the Surviving Corporation shall deliver to a depository or trust institution of recognized standing selected by AREP Oil & Gas and reasonably acceptable to the Company (the “Exchange Agent”) for the benefit of the holders of Shares for exchange in accordance with this Article I: (i) certificates representing the appropriate number of shares of IPO Co. Common Stock issuable pursuant to Section 1.7 as of the Effective Time; and (ii) cash to be paid in lieu of fractional shares of IPO Co. Common Stock (such shares of IPO Co. Common Stock and such cash, together with any dividends or distributions with respect thereto, are hereinafter referred to as the “Exchange Fund”) pursuant to Section 1.9(f) below, in exchange for outstanding Shares.

(b) Not later than two (2) Business Days after the Effective Time, AREP Oil & Gas shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding Shares (the “Certificates”) and whose shares were converted into the right to receive shares of IPO Co. Common Stock pursuant to Section 1.7: (i) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected and risk of loss and title to the Certificates shall pass only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as AREP Oil & Gas and the Company may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of IPO Co. Common Stock, together with any dividends or distributions with respect thereto, and, if applicable, cash to be paid for fractional shares of IPO Co. Common Stock. Upon surrender of a Certificate for exchange and cancellation to the Exchange Agent together with such letter of transmittal duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be issued a certificate representing that number of whole shares of IPO Co. Common Stock and, if applicable, a check representing the cash consideration to which such holder is entitled on account of a fractional share of IPO Co. Common Stock that such holder has the right to receive pursuant to the provisions of this Article I and any dividends or other distributions to which such holder is entitled pursuant to Section 1.9(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, a certificate representing the proper number of shares of IPO Co. Common Stock and a check representing the amount of consideration payable in lieu of fractional shares and any dividends or other distributions to which such holder is entitled pursuant to Section 1.9(c), shall be issued to a transferee if the Certificate representing such Shares is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and

by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 1.9, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of IPO Co. Common Stock and cash in lieu of any fractional shares of IPO Co. Common Stock as contemplated by this Section 1.9 and any other distributions to which such holder is entitled pursuant to Section 1.9(c).

(c) No dividends or other distributions declared or made after the Effective Time with respect to IPO Co. Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of IPO Co. Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 1.9(f), until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of Applicable Law, following surrender of any such Certificate there shall be paid to the record holder of the certificates representing whole shares of IPO Co. Common Stock issued in exchange therefor without interest (i) promptly, the amount of any cash payable in lieu of a fractional share of IPO Co. Common Stock to which such holder is entitled pursuant to Section 1.9(f) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such number of whole shares of IPO Co. Common Stock and (ii) at the appropriate payment date the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of IPO Co. Common Stock.

(d) In the event that any Certificate for Shares shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange therefor upon the making of an affidavit of that fact by the holder of such shares of IPO Co. Common Stock and cash in lieu of fractional shares, if any, as may be required pursuant to this Agreement; provided, however, that AREP Oil & Gas or the Exchange Agent may, in its discretion, require the delivery of a suitable bond or indemnity.

(e) All shares of IPO Co. Common Stock issued upon the surrender for exchange of Shares in accordance with the terms hereof (including any cash paid pursuant to Section 1.9(c) or 1.9(f)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such Shares; subject, however, to IPO Co.’s obligation to pay any dividends or make any other distributions with a record date prior to the date of this Agreement that remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of IPO Co. of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to IPO Co. for any reason, they shall be canceled and exchanged as provided in this Article I.

(f) No fractions of a share of IPO Co. Common Stock shall be issued in the Merger but in lieu thereof each holder of Shares otherwise entitled to a fraction of a share of IPO Co. Common Stock (based upon the aggregate number of shares of IPO Co. Common Stock that would have been issued to such holder absent this provision) shall upon surrender of his or her Certificate or Certificates be entitled to receive an amount of

cash (without interest) determined by multiplying the closing price for IPO Co. Common Stock, as reported by the securities exchange or quotation service on which shares of IPO Co. Common Stock are traded or quoted, on the first Business Day immediately following the Effective Time that such a quote is available, by the fractional share interest to which such holder would otherwise be entitled. For example, if a holder would receive, in the aggregate 100.25 shares of IPO Co. Common Stock in exchange for his aggregate holdings of Company Common Stock, then he would be entitled to receive cash in respect of 0.25 shares of IPO Co. Common Stock. The parties acknowledge that payment of the cash consideration in lieu of issuing fractional shares was not separately bargained for consideration, but merely represents a mechanical rounding off for purposes of simplifying the corporate and accounting complexities that would otherwise be caused by the issuance of fractional shares. From time to time after the Effective Time, as promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional share interests who have surrendered their Certificates to the Exchange Agent, the Exchange Agent shall so notify IPO Co., and IPO Co. shall deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional share interests subject to and in accordance with the terms of Sections 1.9(b) and (c).

(g) Any portion of the Exchange Fund that remains undistributed to the holders of Shares upon the expiration of one (1) year after the Effective Time shall be delivered to IPO Co. upon demand and any holders of Shares who have not theretofore complied with this Article 1 shall thereafter look only to IPO Co. as general creditors for payment of their claim for IPO Co. Common Stock and cash in lieu of fractional shares, as the case may be, and any applicable dividends or distributions with respect to IPO Co. Common Stock.

(h) Neither the Surviving Corporation nor IPO Co. shall be liable to any holder of Shares or IPO Co. Common Stock for such shares (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Applicable Law.

(i) Each of IPO Co. and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state or local tax Law. To the extent that amounts are so withheld by IPO Co. or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by IPO Co. or the Exchange Agent, as the case may be.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company hereby represents and warrants to AREP Oil & Gas and IPO Co., subject to the exceptions set forth in the Disclosure Schedule (the “Company Disclosure Schedule”) delivered by the Company to AREP Oil & Gas and IPO Co. in accordance with Section 4.10 (which exceptions shall specifically identify a Section, Subsection or clause of a single Section or Subsection hereof, as applicable, to which such exception relates) that:

Section 2.1 Organization.

(a) Each of the Company and its subsidiaries is duly organized, validly existing and, except as set forth in Section 2.1 of the Company Disclosure Schedule, in good standing under the laws of the jurisdiction of its incorporation or organization and has all requisite power and authority to own, lease and operate its properties and to carry on its businesses as now being conducted. Except as set forth in Section 2.1(a) of the Company Disclosure Schedule, the Company has no operating subsidiaries other than those incorporated in a state of the United States.

(b) Except as set forth in Section 2.1(b) of the Company Disclosure Schedule, each of the Company and its subsidiaries is duly qualified or licensed and in good standing to do business in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary, except in such jurisdictions where the failure to be so duly qualified or licensed and in good standing would not, individually or in the aggregate, have a Material Adverse Effect on the Company. When used in connection with the Company or its subsidiaries, the term “Material Adverse Effect on the Company” means any circumstance, change in, or effect on the Company and its subsidiaries, taken as a whole, that is, or is reasonably likely in the future to be, materially adverse to the operations, financial condition, earnings or results of operations, or the business (financial or otherwise), of the Company and its subsidiaries, taken as a whole, provided that none of the following shall be deemed, either alone or in combination, to constitute a Material Adverse Effect on the Company: (i) a change in the market price or trading volume of the Company Common Stock; (ii) a failure by the Company to meet internal earnings or revenue projections or the revenue or earnings predictions of equity analysts, or any other revenue or earnings predictions or expectations, for any period ending (or for which earnings are released) on or after the date of this Agreement and prior to the Effective Date, provided further that this Section 2.1(b)(ii) shall not exclude any underlying change, effect, event, occurrence, state of facts or developments which resulted in such failure to meet such estimates, predictions or expectations; (iii) conditions affecting the oil and gas industry as a whole or the U.S. economy as a whole; or (iv) any disruption of customer or supplier relationships arising primarily out of or resulting primarily from actions contemplated by the parties in connection with the announcement of this Agreement and the transactions contemplated hereby, to the extent so attributable.

Section 2.2 Capitalization.

(a) The authorized capital stock of the Company consists of Fifteen Million (15,000,000) Shares, of which, as of the date of this Agreement, 11,190,650 Shares were issued and outstanding and One Million (1,000,000) shares of preferred stock, no shares of which are outstanding. All of the outstanding Shares have been validly issued and are fully paid, nonassessable and free of preemptive rights. As of the date of this Agreement, there are outstanding (i) no shares of capital stock or other voting securities of the Company, except as set forth above, (ii) no securities of the Company or any of its subsidiaries convertible into or exchangeable or exercisable for shares of capital stock or other securities of the Company, (iii) no options, preemptive or other rights to acquire from the Company or any of its subsidiaries, and, except as described in the Company SEC Reports (as defined below), no obligations of the Company or any of its subsidiaries to issue any capital stock, voting securities or securities convertible into or exchangeable or exercisable for capital stock or other securities of the Company and (iv) no equity equivalent interests in the ownership or earnings of the Company or its subsidiaries or other similar rights other than as set forth in the limited liability company operating agreement of NEG Holding LLC (collectively “Company Securities”). Except as set forth in Section 2.2(a) of the Company Disclosure Schedule, as of the date of this Agreement, there are no outstanding rights or obligations of the Company or any of its subsidiaries to repurchase, redeem or otherwise acquire any Company Securities. There are no stockholder agreements, voting trusts or other agreements or understandings to which the Company is a party or by which it is bound relating to the voting or registration of any shares of capital stock of the Company.

(b) All of the outstanding capital stock of the Company’s subsidiaries owned by the Company is owned, directly or indirectly, free and clear of any Lien or any other limitation or restriction (including any restriction on the right to vote or sell the same except as may be provided as a matter of Applicable Law). Except as set forth in Section 2.2(b) of the Company Disclosure Schedule, there are no (i) securities of the Company or any of its subsidiaries convertible into or exchangeable or exercisable for, (ii) options to acquire or (iii) other rights to acquire from the Company or any of its subsidiaries, any capital stock or other ownership interests in or any other securities of any subsidiary of the Company, and there exists no other contract, understanding, arrangement or obligation (whether or not contingent) providing for the issuance or sale, directly or indirectly, of any such capital stock. There are no outstanding contractual obligations of the Company or its subsidiaries to repurchase, redeem or otherwise acquire any outstanding shares of capital stock or other ownership interests in any subsidiary of the Company. For purposes of this Agreement, “Lien” means, with respect to any asset (including any security), any mortgage, lien, pledge, charge, security interest or encumbrance of any kind in respect of such asset; provided, however, that the term “Lien” shall not include (i) statutory liens for taxes that are not yet due and payable or are being contested in good faith by appropriate proceedings and are disclosed in Section 2.2(b) of the Company Disclosure Schedule or that are otherwise not material, (ii) statutory or common law liens to secure obligations to landlords, lessors or renters under leases or rental agreements confined to the premises rented, (iii) deposits or pledges made in connection with, or to secure payment of, workers’ compensation, unemployment

insurance, old age pension or other social security programs mandated under Applicable Laws, (iv) statutory or common law liens in favor of carriers, warehousemen, mechanics and materialmen, to secure claims for labor, materials or supplies and other like liens, and (v) restrictions on transfer of securities imposed by applicable state and federal securities laws.

(c) The Shares constitute the only class of equity securities of the Company or its subsidiaries registered or required to be registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

[DATE]

Ladies and Gentlemen:

The undersigned, a holder of shares of common stock, par value $0.01 per share, of National Energy Group, Inc., a Delaware corporation (the “Company”), is entitled to receive in exchange for such shares, in connection with the merger (the “Merger”) of the Company with and into NEG IPOCO, INC., a Delaware corporation (“IPO Co.”), shares of Common Stock, par value $.01 per share, of IPO Co. (“IPO Co. Common Stock”). The undersigned acknowledges that the undersigned may be deemed an “affiliate” of the Company as that term is defined for purposes of Rule 145 (“Rule 145”) promulgated under the Securities Act of 1933, as amended (the “Act”), although nothing contained herein should be construed as an admission of such fact or as a waiver of any rights the undersigned may have to object to any claim that the undersigned is such an affiliate on or after the date of this letter.

If in fact the undersigned is an “affiliate” of the Company under the Act, the undersigned’s ability to sell, assign or transfer the IPO Co. Common Stock received by the undersigned pursuant to the Merger may be restricted unless such transaction is registered under the Act or an exemption from such registration is available. The undersigned understands that such exemptions are limited and the undersigned has obtained advice of counsel as to the nature and conditions of such exemptions, including information with respect to the applicability to the sale of such securities of Rules 144 and 145(d) promulgated under the Act. The undersigned understands that, except as set forth in the Agreement and Plan of Merger, dated as of December 7, 2005, among AREP Oil & Gas, IPO Co. and the Company, IPO Co. is under no obligation to register the sale, transfer or other disposition of the IPO Co. Common Stock by, or on behalf of, the undersigned or to take any other action necessary in order to make compliance with an exemption from such registration available; provided, however, that IPO Co. will use commercially reasonable efforts to file the reports required to be filed by it under the Securities Exchange Act of 1934, as amended, to the extent required to enable the undersigned to sell IPO Co. Common Stock in accordance with Rules 144 and 145 promulgated under the Act.

The undersigned hereby represents to and covenants with IPO Co. that the undersigned will not sell, assign, transfer or otherwise dispose of any of the IPO Co. Common Stock received by the undersigned pursuant to the Merger except (i) pursuant to an effective registration statement under the Act, (ii) in conformity with the volume and other applicable limitations of Rules 144 and 145 promulgated under the Act or (iii) in a transaction which, in the opinion of counsel reasonably satisfactory to IPO Co. or as described in a “no-action” or interpretive letter from the Staff of the Securities and Exchange Commission, is not required to be registered under the Act.

In the event of a sale or other disposition by the undersigned of IPO Co. Common Stock received by the undersigned in the Merger pursuant to Rule 145, the undersigned will supply IPO Co. with evidence reasonably satisfactory to IPO Co. of compliance with Rule 145. The undersigned understands that IPO Co. may instruct its transfer agent to withhold the transfer of shares of IPO Co. Common Stock sold or disposed of by the undersigned, subject to receipt of such evidence of compliance. Following such receipt, IPO Co. shall instruct the transfer agent to effectuate the transfer of the IPO Co. Common Stock sold or disposed of by the undersigned.

The undersigned acknowledges and agrees that there will be placed on certificates representing IPO Co. Common Stock (or on confirmations and account statements for shares of IPO Co. Common Stock held in book-entry form) received by the undersigned in the Merger or held by a transferee thereof a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIES AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH THE REQUIREMENTS OF RULE 145 OR PURSUANT TO A REGISTRATION STATEMENT UNDER THAT ACT OR AN EXEMPTION FROM SUCH REGISTRATION.”

The undersigned acknowledges and agrees that the legend and stop orders set forth above will be removed (i) upon receipt of evidence or representations satisfactory to IPO Co. that the IPO Co. Common Stock represented by such certificates are being or have been sold in a transaction made in conformity with the provisions of Rule 145 (as such rule may be hereafter amended) or if such certificates are being or have been sold in a transfer registered under the Act or (ii) upon receipt of an opinion in form and substance reasonably satisfactory to IPO Co. from counsel reasonably satisfactory to IPO Co. to the effect that such legends are no longer required for purposes of the Act.

The undersigned acknowledges that (i) the undersigned has carefully read this letter and understands the requirements hereof and the limitations imposed upon the distribution, sale, transfer or other disposition of securities and (ii) the receipt by AREP Oil & Gas of this letter is an inducement and a condition to AREP Oil & Gas’s obligations to consummate the Merger.

Very truly yours,

[STOCKHOLDER]

To the maximum extent permitted by applicable Delaware law, in the event that a director, officer or employee of the Corporation who is also a Founding Stockholder or Specified Party acquires knowledge of a potential transaction or matter that may be a corporate opportunity or otherwise is then exploiting any corporate opportunity, subject to Section 3(b) of this Article Tenth, the Corporation shall have no interest in such corporate opportunity and no expectation that any corporate opportunity be offered to the Corporation, any such interest or expectation being hereby renounced, so that, as a result of such renunciation, and for the avoidance of doubt, such Founding Stockholder or Specified Party (i) shall have no duty to communicate or present such corporate opportunity to the Corporation, (ii) shall have the right to hold any such corporate opportunity for its own account or to recommend, sell, assign or transfer such corporate opportunity to persons other than the Corporation and (iii) shall not breach any fiduciary duty to the Corporation by reason of the fact that such Founding Stockholder or Specified Party pursues or acquires any such corporate opportunity for itself or directs, sells, assigns or transfers such corporate opportunity to another person or does not communicate information regarding such corporate opportunity to the Corporation.

b. Notwithstanding the provisions of Sections 2 and 3(a) of this Article Tenth, the Corporation does not renounce any interest or expectation it may have in any corporate opportunity that is offered to any Founding Stockholder or Specified Party, if such opportunity is expressly offered to such Founding Stockholder or Specified Party solely in, and as a direct result of, his or her capacity as a director, officer or employee of the Corporation.

c. No amendment or repeal of this Section 3 of this Article Tenth shall apply to or have any effect on the liability or alleged liability of any Founding Stockholder or Specified Party for or with respect to any corporate opportunity of which such Founding Stockholder or Specified Party becomes aware prior to such amendment or repeal.

4. Certain Matters Deemed Not Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this Article Tenth, a corporate opportunity shall not be deemed to belong to the Corporation, and the Corporation hereby renounces any interest therein, if it is a business opportunity that the Corporation is not financially able, contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectation.

5. Certain Definitions. For purposes of this Article Tenth only, (i) the term “Corporation” shall mean the Corporation and all corporations, limited liability companies, partnerships, joint ventures, associations and other entities in which the Corporation beneficially owns (directly or indirectly) fifty percent (50%) or more of the outstanding voting stock, voting

power or similar voting interests, except that for purposes of determining those persons who are directors of the Corporation, such term shall mean the Corporation without regard to any other entities in which it may hold an interest, (ii) the term “Founding Stockholder” shall mean American Real Estate Partners, L.P. (“AREP”) and its affiliates (other than the Corporation) and any other persons in which AREP or any such affiliate has any direct or indirect voting or economic interest, (iii) the term “affiliate”, when used with reference to any person, shall mean a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such person, (iv) the term “control” (including the terms controlling, controlled by and under common control with) means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting securities, by contract, or otherwise, and (v) the term “person” shall mean an individual, partnership, limited partnership, limited liability company, corporation, trust, estate, association or any other entity.

6. Expiration of Certain Provisions.

Neither the alteration, amendment, change or repeal of any provision of this Article Tenth nor the adoption of any provision of this Certificate of Incorporation inconsistent with any provision of this Article Tenth shall eliminate or reduce the effect of this Article Tenth in respect of any matter occurring, or any cause of action, suit or claim that, but for this Article Tenth, would accrue or arise prior to such alteration, amendment, repeal or adoption.

7. Deemed Notice. Any person or entity purchasing or otherwise acquiring any interest in any shares of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article Tenth.

Calculation of Percentage

all numbers below are hypothetical assumptions used solely for the purpose of this example

Assumptions for Merger

1. Following the Merger, capital accounts in AREP Oil & Gas will be reflected at Fair Market Value.

2. Assume that, following the Merger, (i) the NEG Holding LLC interest is contributed to AREP Oil & Gas and (ii) capital accounts in AREP Oil & Gas are as follows: (x) AREH, $920, and (y) IPO Co., $80.

3. Assume that net indebtedness of the Enterprise is $500 million immediately prior to or simultaneously with the consummation of the IPO Transaction.

Result

Stock held in IPO Co. would be as follows: (i) AREH, 25,050,001 common; (ii) NEG public holders, 24,949,999 common; and (iii) XXXX, 0 Class B Common.

Assumptions for IPO

IPO Co. raises $380 and contributes this amount to AREP Oil & Gas and issues 232,485,878 shares of common stock to its new public stockholders (the “New Holders”).

Result

A. The capital accounts in AREP Oil & Gas are as follows: (i) AREH, $920; and (ii) IPO Co., $460. Following $250 distribution to AREH, AREH’s capital account is reduced to $670.

B. The holders of IPO Co. stock are as follows:

(i) AREH, 25,050,001 common
(ii) NEG public holders, 24,949,999 common
(iii) New Holders, 232,485,878 common
(iv) XXXX, 0 Class B Common

C. The interest of AREH in AREP Oil & Gas is convertible into 411,432,340 shares of IPO Co. Common Stock (the “Convertible Amount”). The Class B Common share is entitled to a number of votes as a common holder equal to the Convertible Amount.

Debt Adjustment

If net indebtedness of the Enterprise is not $500 million immediately prior to or simultaneously with the consummation of the IPO Transaction, then the Percentage shall be adjusted in accordance with the following examples:

Example 1

If net indebtedness of the Enterprise is $500 million immediately prior to or simultaneously with consummation of the IPO Transaction, then the Percentage shall be 7.990%

Example 2

If net indebtedness of the Enterprise is $430 million immediately prior to or simultaneously with consummation of the IPO Transaction, then the Percentage shall be calculated as follows:

7.990 — (0.6322 x 70/100) = 7.54746%

Example 3

If net indebtedness of the Enterprise is $350 million immediately prior to or simultaneously with consummation of the IPO Transaction, then the Percentage shall be calculated as follows:

7.990 — (0.6322 x 150/100) = 7.0417%

Example 4

If net indebtedness of the Enterprise is $570 million immediately prior to or simultaneously with consummation of the IPO Transaction, then the Percentage shall be calculated as follows:

7.990 + (0.6322 x 70/100) = 8.43254%

Example 5

If net indebtedness of the Enterprise is $650 million immediately prior to or simultaneously with consummation of the IPO Transaction, then the Percentage shall be calculated as follows:

7.990 + (0.6322 x 150/100) = 8.9383%
