("EPL") Recipients of Earn Out: As provided in the Merger Agreement and related documents Earn Out Representative: Bruce R. Sidner (or such other person as shall be designated by Gary L. Hall or in his absence in order of designation, Wayne P. Hall or John H. Peper) Maximum Earn Out Value: $50 million Form of Payment: Subject to EPL shareholder approval (if required and for which EPL agrees to seek approval), registered shares of EPL Common Stock, valued as of the Calculation Date to which such payment relates, or at EPL's option, cash; provided, however, that a minimum of 20% of each such payment to each recipient shall be paid in cash, subject to limitations should there exist a default under EPL's then current bank credit facility terms (the aggregate value of all payments made as of each Earn Out Payment Date shall be referred to as the "Earn Out Payment" attributable to that Earn Out Payment Date) Earn Out Term: January 1, 2002 through December 31, 2005 Earn Out Calculation Dates: March 1 (or the first business day thereafter) of each year commencing with 2003 and ending with 2007 (in each instance, as applicable, the "Earn Out Calculation Date") Earn Out Payment Dates: Ten (10) business days following each Earn Out Calculation Date Ring Fenced Properties: Those Oil and Gas Properties listed in Section 3.12 (a) to the Disclosure Schedule (the "Ring Fenced Properties"). Other oil and gas interests (within which oil and/or gas prospect drilling opportunities have been identified) may be acquired and will thereafter be included in the Ring Fenced Properties at the request of the Earn Out Representative, provided that such interest is acquired by utilizing as trade consideration an interest in one or more of the then existing Ring Fenced Properties, and provided further that any such exchange shall be subject to the sole discretion of EPL after taking into account all drilling opportunities then available to EPL Reserves Included in Earn Out Calculation: Those net proved reserves (all categories) attributable to the Ring Fenced Properties (the "Earn Out Reserves") that are not associated with the reservoirs and fault blocks reflected in the Ryder Scott Company reserve report prepared as of November 1, 2001 for Hall-Houston Oil Company and furnished to EPL (the "Excluded Reserves"), including any such net proved reserves as might be sold subsequent to their discovery Earn Out Reserves Valuation: On or before each Earn Out Calculation Date, EPL will cause the Earn Out Reserves booked during the period from January 1, 2002 through December 31 of the calendar year preceding such Earn Out Calculation Date and the pre-tax income attributable thereto from January 1, 2002 forward to be estimated by the Independent Reservoir Engineering Firm (defined as the independent reservoir engineering firm initially selected by EPL and the Earn Out Representative, which shall be selected upon the closing of the Merger, or such other independent reservoir engineering firm as may be mutually agreed upon between EPL and the Earn Out Representative) using, except as otherwise provided under the heading "Earn Out Specific Valuation Criteria", the same criteria and methodology as are used in preparing such reserve estimates for SEC reporting purposes (the "Reserves Valuation") combined with prices and cost escalations as defined in the following section Earn Out Specific Valuation Criteria: The portion of the Earn Out Reserves attributable to each well included in the Reserves Valuation will be discounted back to January 1 of the year in which the initial capital expenditures for such well were recorded in the accounting records of EPL The before tax net present value attributable to each such well will be calculated using mid-year discounting and a 30% per annum discount rate In the event a dry hole or non-commercial well is drilled to test potential Earn Out Reserves, the cost of such well will be included in the Reserves Valuation for the year in which the initial capital expenditures for such well were recorded in the accounting records of EPL All historical cost and revenue information attributable to the Ring Fenced Properties, including revenue from the sale of Earn Out Reserves in place, through December 31 of the calendar year preceding the Earn Out Calculation Date as recorded in the general ledger of EPL, where available, will be used in each Reserves Valuation Oil/condensate and natural gas prices used in each Reserves Valuation for periods subsequent to December 31 of the calendar year preceding the Earn Out Calculation Date to which it relates will equal the arithmetic average of: a) NYMEX Settlements, which are defined as the arithmetic average of the settlement prices for each calendar year for West Texas Intermediate (WTI) light sweet crude oil or Henry Hub natural gas, as applicable, as published by the New York Mercantile Exchange ("NYMEX"), in each instance for the last three trading days of the then prompt NYMEX January natural gas contract during the month of December preceding such Earn Out Calculation Date for which prices are quoted and b) The oil and natural gas price forecast of the agent under EPL's then existing credit facility (the "Bank Facility Price Forecast") most recently available as of December 31 of the calendar year preceding the Earn Out Calculation Date for such year To the extent that annual prices are not quoted by the NYMEX or set forth in the Bank Facility Price Forecast, then the monthly or quarterly prices so quoted or set forth for such calendar year will be converted to the appropriate arithmetic averages that comprise an annual average to be used in the aforementioned price computations, and calendar years for which there are no prices quoted by the NYMEX or set forth in the Bank Facility Price Forecast, the price for the preceding calendar year, escalated as provided below Oil/condensate and natural gas prices used in each Reserves Valuation for periods subsequent to December 31 of the calendar year preceding the Earn Out Calculation Date to which it relates will be adjusted to account for reasonable estimates of transportation and basis adjustment charges to reflect the difference between NYMEX prices and prices received at the sales meter for the reserves in question Future costs and, to the extent provided above, future oil and natural gas prices will be adjusted for the Bank Facility Inflation Forecast (defined as the inflation price forecast of the agent under EPL's then existing credit facility most recently available as of December 31 of the calendar year preceding the Earn Out Calculation Date or, in the absence of such inflation price forecast, 3% per annum) When applicable, operating costs will include a portion of general and administrative expenses allocated directly to the leases and wells under the terms of applicable operating agreements or, in the absence of an operating agreement, under standard COPAS provisions similar to those found in operating agreements applicable to the Ring Fenced Properties for which there are operating agreements (in either instance, "Standard COPAS Provisions"); no deduction will be made for indirect costs such as indirect general administration and overhead expenses other than those provided for under Standard COPAS Provisions. All assumptions furnished to the Independent Reservoir Engineering Firm for purposes of calculating each Reserves Valuation provided for herein shall be determined in good faith and on a basis considered reasonable by EPL, after consultation with the Earn Out Representative or his agents Future lease operating expenses attributable to a structure with more than one well shall be allocated on an active, well-count basis, unless otherwise provided under Standard COPAS Provisions, and no well shall be charged with any existing infrastructure cost, such as facility capital, previously attributable to any other well or wells in which EPL or its subsidiaries (including Hall-Houston Oil Company) have an interest Earn Out Payment Amount as of Each Earn Out Calculation Date: The percentage of the Reserves Valuation set forth below as of the Earn Out Valuation Date in question, less the amounts, if any, of all prior Earn Out Payments made in respect of the Earn Out, shall be paid to each recipient of the Earn Out Consideration as of the Earn Out Payment Date to which it relates: ----------------------------------- ---------------------------- Earn Out Calculation Date Earn Out Percentage ----------------------------------- ---------------------------- ----------------------------------- ---------------------------- March 3, 2003 20% ----------------------------------- ---------------------------- ----------------------------------- ---------------------------- March 1, 2004 30% ----------------------------------- ---------------------------- ----------------------------------- ---------------------------- March 1, 2005 35% ----------------------------------- ---------------------------- ----------------------------------- ---------------------------- March 1, 2006 40% ----------------------------------- ---------------------------- ----------------------------------- ---------------------------- March 1, 2007 50% ----------------------------------- ---------------------------- Capital Commitment to Ring Fenced Properties: Notwithstanding anything herein to the contrary, EPL will agree to commit $13 million of capital (the "Capital Commitment Amount") for the drilling and evaluation of HHOC's interest in four wells to be drilled as designated by the Earn Out Representative to test the oil and gas prospect potential associated with HHOC's current leasehold interest in Green Canyon Blocks 9 and 10 (two wells), East Cameron 378 (one well) and Eugene Island 376 (one well), such capital to be provided so as to permit the drilling of all of such wells to commence on or before June 30, 2003; provided, however, the drilling of any of such wells may be delayed for such period of time as the Earn Out Representative shall determine in his sole discretion but not to extend past December 31, 2005. Drilling Decision Criteria: Except for the drilling of the wells provided for above with the Capital Commitment Amount, EPL's obligation to drill any wells to test any prospect potential associated with the Ring Fenced Properties and develop any reserves associated therewith will be subject to the following non-exclusive list of criteria (provided that decisions with respect thereto will be made consistent with the criteria used in evaluating all exploration and development opportunities then being considered by EPL, acting through its Investment Advisory Committee): A minimum projected after tax rate of return to EPL (before giving consideration to the Earn Out) A maximum projected finding & development cost Notwithstanding the foregoing, EPL may elect to include projects that do not meet the above criteria. Further, all parties recognize that the establishment and interim adjustment, if any, of EPL's annual capital budget shall in all events remain subject to approval by EPL's Board of Directors.

Payment made pursuant to clause (c) above may be made, at the option of the Holder: (x) by cash, money order, certified or bank cashier's check or wire transfer, (y) the surrender to the Company of securities of the Company having a Fair Market Value equal to the aggregate Exercise Price or (z) the delivery of a notice to the Company that the Holder is exercising this Warrant by authorizing the Company to reduce the number of shares of Common Stock subject to this Warrant by the number of shares having an aggregate Fair Market Value equal to the aggregate Exercise Price. The Company shall, as promptly as practicable thereafter, execute and deliver or cause to be executed and delivered, in accordance with such notice, a certificate or certificates representing the aggregate number and type of shares of Common Stock specified in said notice. The share certificate or certificates so delivered shall be in such denominations as may be specified in such notice or, if such notice shall not specify denominations, shall be in the number of shares of Common Stock for which the Warrant is being exercised, and shall be issued in the name of the Holder or such other name or names as shall be designated in such notice, subject to Section 1.4. Such certificate or certificates shall be deemed to have been issued, and such Holder or any other Person so designated to be named therein shall be deemed for all purposes to have become a holder of record of such shares, as of the date the aforementioned notice is received by the Company. If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of the certificate or certificates, deliver to the Holder a new Warrant evidencing the rights to purchase the remaining shares of Common Stock called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or, at the request of the Holder, appropriate notation may be made on this Warrant which shall then be returned to the Holder.

All shares of Common Stock issued upon the exercise of this Warrant shall be validly issued, fully paid and nonassessable and free from all preemptive rights of any stockholder, and from all taxes, liens and charges with respect to the issue thereof (other than transfer taxes).

The Company shall not be required to issue fractions of shares of Common Stock upon exercise of this Warrant. If any fraction of a share would, but for this Section 1.3, be issuable upon any exercise of this Warrant, in lieu of such fractional share the Company shall pay to the Holder, in cash, an amount equal to such fraction of the Fair Market Value per share of outstanding Common Stock of the Company on the Business Day immediately prior to the date of such exercise. 1.4 Share Legends.

Exhibit D to Merger Agreement [FORM OF DEBT EXCHANGE AGREEMENT] DEBT EXCHANGE AGREEMENT (this "Agreement"), dated as of December 16, 2001, is by and among Energy Partners, Ltd., a Delaware corporation ("Buyer"), and each of the parties listed on Schedule I to this Agreement (each, a "Holder" and together, the "Holders"). W I T N E S S E T H : - - - - - - - - - - WHEREAS, each Holder is a holder of an evidence of indebtedness of Hall-Houston Oil Company (the "Company"), bearing interest and with the maturity or maturities set forth opposite such Holder's name on Schedule I (each a "Note" and collectively the "Notes"); WHEREAS, together the Holders hold $80,155,618 in principal amount of such indebtedness of the Company; WHEREAS, pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated as of December 16, 2001, by and among Buyer, a wholly owned subsidiary of Buyer and the Company, a copy of which is attached hereto as Annex I, it is a condition to the consummation of the Merger (as defined in the Merger Agreement) that Buyer enter into this Agreement with Holders of at least 80% of the Note Indebtedness (as defined below) to exchange such Holders' Notes and all related interest, fees and penalties, if any, accrued and unpaid thereon to the Effective Date (as defined in the Merger Agreement) (together, the "Note Indebtedness") for (i) 5 shares of Series D Exchangeable Convertible Preferred Stock liquidation value $100 per share (the "Preferred Stock"), of Buyer, per $1,000 principal amount of Notes; (ii) $500 aggregate principal amount of Buyer's 11% Senior Subordinated Notes due 2009 (the "Exchange Notes") per $1,000 principal amount of Notes; (iii) cash in full payment of "Nominal Overriding Royalty Interests" provided for in documentation relating to certain series of Notes; and (iv) cash in an amount equal to the accrued and unpaid interest to the Closing (as defined below) on the Notes (such cash amounts provided for in (iii) and (iv), the "Cash Consideration" and, together with the Exchange Notes and the Preferred Stock, the "Exchange Consideration"). NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and promises herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. Exchange of Note Indebtedness for the Exchange Consideration. Each Holder shall acquire from Buyer at the Closing (as defined below), and Buyer shall issue and deliver to each Holder, the Exchange Consideration applicable to such Holder's Note Indebtedness in exchange for all Notes representing Note Indebtedness. The failure of any Holder to execute this Agreement or to perform its obligations hereunder shall not affect the performance obligations hereunder of any other Holder. Buyer may pay cash in lieu of issuing Preferred Stock and Exchange Notes in amounts less than $500. 2. The Closing. The closing of the exchange of the Note Indebtedness for the Exchange Consideration contemplated hereby (the "Closing") shall take place at a location mutually -2- agreeable to Buyer and Company, at 9:00 a.m. local time on January 8, 2002 or such later time and date determined by Buyer, which shall be immediately prior to the closing pursuant to the Merger Agreement (the "Closing Date"). Prior to the Closing each Holder shall have delivered to the Custodian (the "Custodian") specified in the Custody Agreement and Power of Attorney in the form attached hereto as Annex II (the "Custody Agreement") the Notes held by such Holder in accordance with the provisions of the Custody Agreement. At the Closing Buyer shall deliver to the Custodian, for the benefit of each Holder, (i) certificates, in the name of such Holder or its successors, assigns or designees, evidencing the acquisition by such Holder of the Preferred Stock allocable to such Holder; (ii) the Exchange Notes made payable to such Holder or its successors, assigns or designees, allocable to such Holder; and (iii) by check or wire transfer of immediately available funds, cash in an amount equal to the Cash Consideration allocable to such Holder. Simultaneously at the Closing the Custodian shall deliver to Buyer the Notes held by each Holder with the appropriate notation that such Notes have been canceled. Upon the exchange of the Exchange Consideration for the Notes, such Holder hereby releases, fully acquits and forever discharges the Company, its subsidiaries, stockholders, officers, directors, successors and assigns from any and all debt, late fees, prepayment fees, penalties, interest and causes of action with respect to the Note Indebtedness. 3. Representations and Warranties of Buyer. The representations and warranties of Buyer in Article IV of the Merger Agreement are incorporated herein for the benefit of the Holders. 4. Post-Closing Covenants of Buyer. 4.1. Maintenance of Authorized Shares. Buyer shall at all times reserve authorized shares of Common Stock sufficient to permit the conversion of all shares of Preferred Stock in accordance with the terms thereof. 4.2. Registration and Listing. If any shares of Common Stock required to be reserved for purposes of conversion of the shares of Preferred Stock as provided in the Certificate of Designation of the Preferred Stock require registration with or approval of any governmental authority under any Federal or state or other applicable law or listing subject to issuance on the national securities exchange on which the Common Stock is quoted or listed, in each case before such Common Stock may be issued or delivered upon conversion, Buyer will in good faith and as expeditiously as possible endeavor to cause such Common Stock to be duly registered, approved or listed, as the case may be. 4.3. Financial Statements. At any time that Buyer is not subject to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, Buyer shall deliver to each Holder: (a) as soon as available, but not later than 100 days after the end of each fiscal year of Buyer, a copy of the audited consolidated balance sheet of Buyer and its subsidiaries as of the end of such year and the related consolidated statements of income and cash flows for such fiscal year, setting forth in each case in comparative form the figures for the previous year, all in reasonable detail and accompanied by a management summary and analysis of the operations of Buyer and its subsidiaries for such fiscal year and by the opinion of KPMG LLP (or any successor thereto) or another nationally recognized independent public accounting firm, which report shall state that such consolidated financial statements present fairly the fi- -3- nancial position for the periods indicated in conformity with generally accepted accounting principles, applied on a basis consistent with prior years; (b) as soon as available, but in any event not later than 50 days after the end of each of the first three fiscal quarters of each year, the unaudited consolidated balance sheet of Buyer and its subsidiaries, and the related consolidated statements of income and cash flow for such quarter and for the period commencing on the first day of the fiscal year and ending on the last day of such quarter, all certified by Buyer's Chief Financial Officer; and (c) to the extent not covered above, as soon as practicable any materials delivered to all stockholders of Buyer. 5. Representations and Warranties of the Holders. Each Holder, severally and not jointly, represents and warrants to Buyer as follows: 5.1. Ownership. Such Holder is the sole owner of such Holder's Notes free and clear of any lien, claim, security interest, or other encumbrance of any kind or nature whatsoever and has the complete power to transfer and deliver such Holder's Notes to Buyer, as contemplated by this Agreement, free and clear of all liens, claims, security interests, mortgages, charges, options, pledges and encumbrances (collectively, "Encumbrances"). Upon transfer to Buyer by such Holder of its Notes, Buyer will have good and marketable title to such Notes, free and clear of all Encumbrances. 5.2. Holder Status. Such Holder is an Accredited Investor within the meaning of Rule 501(a) under the Securities Act of 1933, as amended (the "Securities Act"), and the shares of Preferred Stock, the shares of Common Stock issuable upon conversion of the Preferred Stock, and the Exchange Notes (together, the "Securities") to be acquired by such Holder pursuant to this Agreement are being acquired for its own account without a view toward distribution and such Holder will not offer, sell, transfer, pledge, hypothecate or otherwise dispose of the Securities unless pursuant to a transaction either registered under, or exempt from registration under, the Securities Act. 5.3. Private Placement. (a) Such Holder understands that (i) the exchange of the Securities hereby is intended to be exempt from registration under the Securities Act and (ii) there is only a limited market for the Securities, and there can be no assurance that any Holder will be able to sell or dispose of the Securities to be acquired by such Holder. (b) Such Holder's financial situation is such that such Holder can afford to bear the economic risk of holding the Securities acquired hereunder for an indefinite period of time, and such Holder can afford to suffer the complete loss of the investment in the Securities. (c) Such Holder's knowledge and experience in financial and business matters is such that it is capable of evaluating the merits and risks of the investment in the Securities, or such Holder has been advised by a representative possessing such knowledge and experience. (d) Such Holder understands that the Securities acquired hereunder are a speculative investment which involves a high degree of risk of loss of the entire investment therein, and that -4- for an indefinite period following the date hereof there will be no public market for the Securities and that, accordingly, it may not be possible for such Holder to sell the Securities in case of emergency or otherwise. (e) Such Holder and its representatives, including to the extent it deems appropriate its professional, financial, tax and other advisors, have reviewed all documents provided to them in connection with its investment in the Securities, and such Holder understands and is aware of the risk related to such investment. (f) Such Holder and its representatives have been given the opportunity to examine all documents and to ask questions of, and to receive answers from, Buyer and its representatives concerning the terms and conditions of the acquisition of the Securities and related matters and to obtain all additional information which such Holder or its representatives deem necessary. (g) (i) Such Holder understands that the Securities have not been registered under the Securities Act. Such Holder acknowledges that the Securities are "restricted securities" as defined in Rule 144 under the Securities Act and must be held indefinitely unless subsequently registered under the Securities Act (and any applicable state blue sky laws) or unless an exemption from such registration is available. Such Holder acknowledges that the certificates representing the Securities shall bear a legend substantially as follows, and agrees to comply with such legend: "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION AND MAY NOT BE SOLD, OFFERED FOR SALE OR OTHERWISE TRANSFERRED UNLESS REGISTERED OR QUALIFIED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR UNLESS THE ISSUER RECEIVES AN OPINION OF COUNSEL (WHO MAY BE AN EMPLOYEE OF THE HOLDER) REASONABLY SATISFACTORY TO THE ISSUER THAT REGISTRATION, QUALIFICATION OR OTHER SUCH ACTIONS ARE NOT REQUIRED UNDER SAID ACT. THE OFFERING OF THIS SECURITY HAS NOT BEEN REVIEWED OR APPROVED BY ANY STATE SECURITIES ADMINISTRATOR." (ii) Such Holder, if an executive officer of the Company or one of its subsidiaries on the Closing Date, acknowledges that the shares of Preferred Stock to be acquired by such Holder pursuant to this Agreement and the shares of Common Stock issuable upon conversion of such Preferred Stock shall bear a legend substantially as follows, and agrees to comply with such legend: "THIS SECURITY IS ALSO SUBJECT TO RESTRICTIONS ON TRANSFER CONTAINED IN AN AGREEMENT BETWEEN THE ISSUER AND SUCH HOLDER." 5.4. Authorization. Such Holder, having full right, power and authority to do so, has duly executed and delivered this Agreement and, assuming due execution and delivery hereof by Buyer, this Agreement is the valid and binding obligation of such Holder, enforceable against such -5- Holder in accordance with its terms, except to the extent the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors' rights generally and by general principles of equity. 6.

The holders of the Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for such purpose, dividends payable in accordance with this Section 3. Dividends on the Preferred Stock shall be cumulative and shall accrue semiannually in arrears on June 30 and December 31 (each, a "Dividend Accrual Date") of each year (each six-month period (or such period from the date of original issue until July 15, 2002) expiring on a Dividend Accrual Date being referred to herein as a "Dividend Period"). Dividends on any shares of the Preferred Stock shall be cumulative and shall accrue (whether or not declared and whether or not there shall be funds legally available for the payment of dividends) on and from the date of issue of such shares of the Preferred Stock; provided, however, that dividends in Dividend Shares paid in accordance with Section 3.2 shall be cumulative and shall accrue on and from the Dividend Accrual Date in the Dividend Period in which such dividend accrued, regardless of when such Dividend Shares were actually issued. Dividends payable on the Preferred Stock for any period less than a full Dividend Period shall be computed on the basis of the ratio of the number of days in such partial period to the actual number of days in such full Dividend Period. The date that any dividend shall be paid pursuant to this Section 3.1 is referred to herein as a "Dividend Payment Date." (b) Arrearages. Additional dividends shall accrue with respect to any dividends (including dividends payable pursuant to this sentence) not paid by the Dividend Accrual Date on which such dividend accrues or in the manner provided in Section 3.2. Such additional dividends shall accrue whether or not declared, at the Dividend Rate compounded semiannually, and shall be payable in the same manner and at such times as provided in Section 3.1 and 3.2 hereof with respect to dividends on each outstanding share of Preferred Stock. (c) Fractional Shares. Each fractional share of Preferred Stock outstanding or accrued as a Dividend Share shall be entitled to a ratably proportionate amount of all dividends accruing with respect to each outstanding share of Preferred Stock pursuant to Section 3.1 hereof, and all dividends with respect to such fractional shares shall be fully cumulative and shall accrue (whether or not declared and whether or not there shall be funds legally available for the payment of dividends) and shall be payable in the same manner and at such times as provided for in Sections 3.1 and 3.2 hereof with respect to dividends on each outstanding share of Preferred Stock. 3.2 Form of Payment. -4- (a) Cash. Any dividends accrued on the Preferred Stock on or prior to January 15, 2006 shall when declared be payable in cash at the Dividend Rate per share of Preferred Stock on the stated value of $100. (b) Dividend Shares. Any dividends accrued on the Preferred Stock after January 15, 2006 and on or before January 14, 2009 shall when declared be payable, at the option of the Company, either in cash at the Dividend Rate per share of Preferred Stock on the stated value of $100, or by issuing Dividend Shares having an aggregate stated value equal to the Dividend Rate per share of Preferred Stock on the stated value of $100. 3.3 Record Date. To the extent permitted by applicable law, the Board of Directors shall fix a record date for the determination of holders of the Preferred Stock entitled to receive payment of a dividend declared thereon, which record date shall be not more than 30 days prior to the applicable Dividend Payment Date. 3.4 Restricted Payments. (a) No dividends shall be declared or paid or set apart for payment on the Preferred Stock for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the outstanding Parity Stock for all dividend periods for the Parity Stock terminating on or prior to the date of payment of such dividends. No full dividends shall be declared or paid or set aside for payment on any Parity Stock for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Preferred Stock for all Dividend Periods terminating on or prior to the date of payment of such full cumulative dividends. When dividends are not paid in full, as aforesaid, upon the shares of Preferred Stock and of any other series of Parity Stock, all dividends declared upon shares of Preferred Stock and of any other series of Parity Stock shall be declared pro rata so that the amount of dividends declared per share on the Preferred Stock and such other series of Parity Stock shall in all cases bear to each other the same ratio that accrued dividends per share on the shares of the Preferred Stock and such other series of Parity Stock bear to each other. (b) Unless full cumulative dividends on the Preferred Stock have been paid prior to or on the date of the declaration of dividends on Junior Stock, no dividend shall be declared or paid or set aside for payment or other distribution declared or made upon the Junior Stock. 3.5 Failure to Pay Dividends. If and whenever two consecutive or three total semiannual dividends payable on Preferred Stock have not been paid in full, the number of directors then constituting the Board of Directors shall be increased by one and the holders of a majority of the outstanding shares of Preferred Stock, voting as a single class, shall be entitled to elect the additional director to serve on the Board of Directors at any annual meeting of stockholders or special meeting held in place thereof, or at a special meeting of the holders of the Preferred Stock called as hereinafter provided. Whenever all arrears in dividends on the Preferred Stock then outstanding shall have been paid, then the right of the holders of the Preferred Stock to elect such additional director shall cease -5- (but subject always to the same provisions for the vesting of such voting rights in the case of any similar future arrearage in two consecutive or three total semiannual dividends) and the terms of office of the person elected as director by the holders of the Preferred Stock shall forthwith terminate and the number of the Board of Directors shall be reduced accordingly. At any time after such voting power shall have been so vested in the holders of shares of Preferred Stock, the secretary of the Company may, and upon the written request of any holder of Preferred Stock (addressed to the secretary at the principal office of the Company) shall, call a special meeting of the holders of the Preferred Stock of the Company for the election of the director to be elected by them as herein provided, such call to be made by notice similar to that provided in the Bylaws of the Company for a special meeting of the stockholders or as required by law. If any such special meeting required to be called as above provided shall not be called by the secretary within 20 days after receipt of any such request, then any holder of shares of Preferred Stock may call such meeting, upon the notice above provided, and for that purpose shall have access to the stock books of the Company. The director elected at any such special meeting shall hold office until the next annual meeting of the stockholders or special meeting held in lieu thereof if such office shall not have previously terminated as above provided. If any vacancy shall occur of the director elected by the holders of the Preferred Stock, a successor shall be elected by the Board of Directors, upon the nomination of the holders of the Preferred Stock, to serve until the next annual meeting of the stockholders or special meeting held in place thereof if such office shall not have previously terminated as provided above. SECTION 4. Redemption. 4.1 Optional Redemption. The Company may, at its option on or after January 15, 2005, redeem shares of Preferred Stock, in whole but not in part, at any time, at a redemption price per share equal to $100 plus accrued and unpaid dividends to the date of redemption. 4.2 Redemption Mechanics. (a) Notice. At such time as the Company shall redeem shares of Preferred Stock, notice of such redemption shall be given by first class mail, postage prepaid, mailed not less than 15 nor more than 60 days prior to the redemption date, to each holder of record of the shares to be redeemed, at such holder's address as the same appears on the stock register of the Company. Each such notice shall state: (i) the redemption date; (ii) the number of shares of Preferred Stock to be redeemed; (iii) the redemption price; (iv) the place or places where certificates for such shares are to be surrendered for payment of the redemption price; (v) that dividends on the shares to be redeemed will cease to accrue on such redemption date; and (vi) a description of the conversion rights of the Preferred Stock. (b) Surrender. Notice having been mailed as aforesaid, from and after the redemption date (unless default shall be made by the Company in providing money for the payment of the redemption price) dividends on the shares of Preferred Stock so called for redemption shall cease to accrue, said shares shall no longer be deemed to be outstanding, and all rights of the holders thereof as stockholders of the Company (except the right to receive from the Company the redemption price -6- plus accrued and unpaid dividends to the redemption date) shall cease. Upon surrender in accordance with said notice of the certificates for any shares so redeemed (properly endorsed or assigned for transfer, if the Board shall so require and the notice shall so state), such shares shall be redeemed by the Company at the redemption price aforesaid. 4.3 Status of Preferred Stock After Redemption. Any shares of Preferred Stock that shall at any time have been redeemed or purchased by the Company shall, after such redemption, have the status of authorized but unissued shares of preferred stock, without designation as to series until such shares are once more designated as part of a particular series by the Board. SECTION 5. Exchange. 5.1 Exchange of Preferred Stock for Exchange Notes. The Company may, at its option, subject to the conditions set forth below, on any scheduled Dividend Payment Date, exchange the Preferred Stock, in whole but not in part, together with any accrued and unpaid dividends, for an equal principal amount of Exchange Notes; provided that on the date of such exchange there is no contractual impediment to such exchange. 5.2 Form of Exchange Notes. Upon any exchange pursuant to Section 5.1, holders of outstanding shares of Preferred Stock will be entitled to receive $100 principal amount of Exchange Notes for each $100 stated value of Preferred Stock and accrued and unpaid dividends thereon held by them. The Exchange Notes will be issued in registered form, without coupons. Exchange Notes issued in exchange for Preferred Stock and accrued and unpaid dividends thereon will be issued in principal amounts of $1,000 and integral multiples thereof to the extent possible, and will also be issued in principal amounts less than $1,000 so that each holder of Preferred Stock will receive certificates representing the entire amount of Exchange Notes to which such holder's shares of Preferred Stock and accrued and unpaid dividends thereon entitle such holder; provided that the Company may pay cash in lieu of issuing an Exchange Note in a principal amount less than $1,000. The person entitled to receive the Exchange Notes issuable upon such exchange will be treated for all purposes as the registered holder of such Exchange Notes. 5.3 Exchange Mechanics. (a) Notice. At such time as the Company shall exchange shares of Preferred Stock, notice of such exchange shall be given by first class mail, postage prepaid, mailed not less than 15 nor more than 60 days prior to the exchange date, to each holder of record of the shares to be exchanged, at such holder's address as the same appears on the stock register of the Company. Each such notice shall state: (i) the exchange date; (ii) the number of shares of Preferred Stock to be exchanged; (iii) the place or places where certificates for such shares are to be surrendered for exchange; (iv) that dividends on the shares to be exchanged will cease to accrue on such exchange date; and (v) a description of the conversion rights of the Preferred Stock. (b) Surrender. Notice having been mailed as aforesaid, from and after the exchange date, dividends on the shares of Preferred Stock so called for exchange shall cease to accrue, said shares shall no longer be deemed to be outstanding, and all rights of the holders thereof as stock- -7- holders of the Company (except the right to receive from the Company the Exchange Notes) shall cease. Upon surrender in accordance with said notice of the certificates for any shares so exchanged (properly endorsed or assigned for transfer, if the Board shall so require and the notice shall so state), such shares shall be exchanged by the Company. 5.4 Status of Preferred Stock After Exchange. Any shares of Preferred Stock that shall at any time have been exchanged or purchased by the Company shall, after such exchange, have the status of authorized but unissued shares of preferred stock, without designation as to series until such shares are once more designated as part of a particular series by the Board. SECTION 6. Liquidation. In the event of any complete liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, the holders of shares of Preferred Stock shall each be entitled to receive out of the assets of the Company legally available for distribution to its stockholders before any distribution shall be made to the holders of Junior Stock of the Company, for each share of Preferred Stock an amount equal to $100 plus accrued and unpaid dividends to the date of payment. If, upon any liquidation, dissolution or winding up of the Company, the assets of the Company, or the proceeds thereof, shall be insufficient to pay in full the preferential amounts as to which the Preferred Stock and any other series of Parity Stock would be entitled, then such assets or the proceeds thereof shall be distributed among holders of Preferred Stock and the holders of any Parity Stock ratably in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. SECTION 7. Conversion. 7.1 (a) Right of Holder to Convert. Provided that full cumulative dividends on the Preferred Stock have been or contemporaneously are declared and paid to the date of conversion, each share of Preferred Stock shall be convertible at the option of the record holder thereof at any time prior to the close of business on the date prior to the redemption date for such share, into the number of shares of fully paid and nonassessable shares of Common Stock determined by dividing $100 by the Conversion Price in effect at the time of conversion. (b) Mechanics of Conversion by Holders of Preferred Stock. In order for any holder of the Preferred Stock to convert the same into Common Stock, such holder shall present in person or by registered mail, return receipt requested with postage prepaid thereon, at the principal office of the Company, the certificate representing such share to the Company by the close of business on the date prior to the redemption date accompanied by written notice to the Company that such holder elects to convert all or a specified number of shares and stating therein its name or the name or names of its nominees in which such holder wishes the certificate or certificates for Common Stock to be issued. The Company shall, as soon as practicable thereafter, issue and deliver to such holder of the Preferred Stock, or to its nominee or nominees, a certificate or certificates representing the number of shares of Common Stock to which such holder shall be entitled as aforesaid, and if less than the full number of shares of the Preferred Stock evidenced by such surrendered certificate or certificates are being converted, a new certificate or certificates, of like tenor, for the number of shares of the Preferred Stock evidenced by such surrendered certificate less the number of such shares being converted. -8- 7.2 Adjustments to Conversion Price for Stock Dividends, Subdivisions and Combinations. In case at any time or from time to time the Company shall (i) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock (whether by distribution of Common Stock or otherwise) or (ii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect immediately after the happening of any such event shall be proportionately decreased, in case of the happening of events described in subparagraph (i) above, or proportionately increased, in case of the happening of events described in subparagraph (ii) above. In case at any time or from time to time the Company shall declare a dividend or make a distribution on the Common Stock payable in shares of its capital stock (other than shares of Common Stock) or capital stock of any subsidiary of the Company or any other assets (other than cash), then the Company shall make appropriate provision to provide the Holder, upon exercise of this Warrant, of the aggregate number and kind of shares which the Holder would have received if the Holder had exercised this Warrant immediately prior to the record date for such dividend or distribution; provided that no adjustment shall be made if such dividend or distribution is not actually made. 7.3 Merger, Consolidation or Disposition of Assets. In case the Company shall merge or consolidate into another corporation, or shall sell, transfer or otherwise dispose of all or substantially all of its property, assets or business to another corporation, then each holder of a share of the Preferred Stock shall have the right thereafter to convert such shares only into the kind and amount of shares of stock and other securities and property receivable upon or deemed to be held following such merger, consolidation, sale, transfer or other disposition of assets by a holder of a number of shares of the Common Stock of the Company into which such shares of Preferred Stock could have been converted immediately prior to such merger, consolidation, sale, transfer or other disposition of assets. In case of any such merger, consolidation, sale, transfer or other disposition of assets, the successor acquiring corporation shall expressly assume the due and punctual observance and performance of each and every covenant and condition hereof to be performed and observed by the Company and all of the obligations and liabilities hereunder, subject to such modification as shall be necessary to provide for adjustments to the Conversion Price which shall be as nearly equivalent as practicable to the adjustments provided for in this Section 7.3.

Conversion (a) (i) Right of Holder to Convert. Each Note shall be convertible at the option of the record holder thereof at any time prior to the close of business on the date prior to the redemption or maturity date for such note, into the number of shares of fully paid and nonassessable shares of common stock of the Company, par value $0.01 per share ("Common Stock"), determined by dividing the principal amount of the Note by $8.54, as adjusted from time to time as set forth in paragraph (b) of this Section 2 (the "Conversion Price") in effect at the time of conversion. (ii) Mechanics of Conversion by Holders of Note. In order for any holder of a Note to convert the same into Common Stock, such holder shall present in person or by registered mail, return receipt requested with postage prepaid thereon, at the principal office of the Company, such Note to the Company by the close of business on the date prior to the redemption or maturity date for such Note accompanied by written notice to the Company that such holder elects to convert all or a specified aggregate principal amount of such Note and stating therein its name or the name or names of its nominees in which such holder wishes the certificate or certificates for Common Stock to be issued.

In case at any time or from time to time the Company shall declare a dividend or make a distribution on the Common Stock payable in shares of its capital stock (other than shares of Common Stock) or capital stock of any subsidiary of the Company or any other assets (other than cash), then the Company shall make appropriate provision to provide the Holder, upon exercise of this Warrant, of the aggregate number and kind of shares which the Holder would have received if the Holder had exercised this Warrant immediately prior to the record date for such dividend or distribution; provided that no adjustment shall be made if such dividend or distribution is not actually made. (c) Merger, Consolidation or Disposition of Assets. In case the Company shall merge or consolidate into another corporation, or shall sell, transfer or otherwise dispose of all or substantially all of its property, assets or business to another corporation, then each holder of a Note shall have the right thereafter to convert such Note only into the kind and amount of shares of stock and other securities and property receivable upon or deemed to be held following such merger, consolidation, sale, transfer or other disposition of assets by a holder of a number of shares of the Common Stock of the Company into which such Note could have been converted immediately prior to such merger, consolidation, sale, transfer or other disposition of assets.

(e) Certificate as to Adjustments.

(f) Notices of Record Date.

Remedies Not Waived. No course of dealing between the Company and the holder of this Note or any delay on the part of the holder hereof in exercising any rights hereunder shall operate as a waiver of any right of any holder of this Note. 17.

(iii) In the event the Company shall default in the payment when due, whether at maturity, at a date fixed for mandatory prepayment, by acceleration or otherwise, of any Senior Indebtedness, and for so long as such default shall continue, the Company will not make, directly or indirectly, to the holder of this Note (and no holder shall accept, receive or retain) any payment or distribution of any kind or character of or on account of all or any part of the indebtedness evidenced by this Note. (iv) Upon receipt by the Company of notice from the holder or holders of any Senior Indebtedness of an event of default (including with respect to any Obligation as defined in the Credit Agreement), no holder of a Note may take action (A) to accelerate or collect payment of this Note, (B) in its capacity as a holder of a Note, commence or join with any other creditor in commencing in any bankruptcy or similar proceeding or (C) to pursue any other remedy with respect to a Note prior to the earlier of (I) the Maturity Date, (II) the payment in full in cash of all Senior Indebtedness or (III) the occurrence of an event specified in paragraph (d) or paragraph (e) of Section 13; provided, however, the holder of a Note will not be prohibited from attending meetings of creditors or filing proofs of claim. -10- Upon request of any holder of Senior Indebtedness, the holder of this Note will reaffirm its obligations under this Section 17.

Subject to the rights, if any, under this Section 17 of holders of Senior Indebtedness to receive cash, property, stock or obligations otherwise payable or deliverable to the holder of this Note, nothing herein shall, as between the holder of this Note and the Company, either impair the obligation of the Company, which is unconditional and absolute, to pay the holder hereof the principal hereof and interest hereon in accordance with the terms and provisions of this Note or prevent the holder of this Note from exercising all remedies otherwise permitted by applicable law or upon default hereunder. (c) No holder of any Senior Indebtedness need at any time give the holder of this Note notice of any kind of the creation or existence of any Senior Indebtedness, nor of the amount or terms thereof, all such notice being expressly waived.

Suits for Enforcement.

Remedies Not Waived. No course of dealing between the Company and the holder of this Note or any delay on the part of the holder hereof in exercising any rights hereunder shall operate as a waiver of any right of any holder of this Note. -7- 16.

(iv) Upon receipt by the Company of notice from the holder or holders of any Senior Indebtedness of an event of default (other than a payment default described in paragraph (iii) above) under any Senior Indebtedness or any event which, with the giving of notice or passage of time, or both, if required, would become such an event of default (and which notice shall specify that it is a Payment Blockage Notice delivered pursuant to this Section 16(a)(iv)), as such event of default is defined therein or in any instrument under which it is outstanding, and such event of default or other such event shall not have been cured or waived in writing or shall not have ceased to exist, no direct or indirect payment or distribution shall be made by the Company with respect to this Note (or accepted, received or retained by any holder hereof) during the period (the "Payment Blockage Period") lasting 180 days from the receipt of such notice by the Company (except as hereinafter provided in this Section 16(a)(iv)).

(c) No holder of any Senior Indebtedness need at any time give the holder of this Note notice of any kind of the creation or existence of any Senior Indebtedness, nor of the amount or terms thereof, all such notice being expressly waived. Also, each holder of Senior Indebtedness may at any time from time to time, without the consent of or notice to any holder of this Note, without incurring responsibility to the holder of this Note, and without impairing or releasing the subordination provisions of this Note (i) renew, refund, refinance, increase or extend the maturity of any Senior Indebtedness, or any part thereof, or otherwise revise, amend or alter the terms and conditions thereof, including without limitation, increasing the amount thereof, (ii) sell, exchange, release or otherwise deal with any property by whomsoever at any time pledged, mortgaged, or otherwise hypothecated or subjected to a lien to secure any Senior Indebtedness, and (iii) exercise or refrain from exercising any rights against the Company and others, including the holder of this Note. (d) In case that, despite the subordination provisions of this Note, any payment or distribution shall be paid or delivered to the holder of this Note in violation or contravention of the -9- terms of this Note before all Senior Indebtedness shall have been paid in full in cash and any and all commitments of the holders of Senior Indebtedness to extend credit to or for the account of the Company shall have terminated or expired, such payment or distribution shall be held in trust for and immediately paid and delivered ratably to the holders of Senior Indebtedness (or their duly authorized representatives), until all Senior Indebtedness shall have been paid in full in cash and the commitments, if any, of all holders of Senior Indebtedness to extend credit to or for the account of the Company shall have terminated or expired. (e) The holders of the Notes hereby undertake and agree for the benefit of the holders of Senior Indebtedness that, upon the occurrence of any of the events set forth in clauses (iii) and (iv) of Section 16(a), the holders shall take any actions reasonably requested by any holder of Senior Indebtedness to effectuate the full benefit of the provisions contained herein.

Purchaser agrees with each Seller as follows: (a) Until the Closing, Purchaser shall comply with the Confidentiality Agreements (as such term is defined in the Agreement and Plan of Merger referred to in clause (e) of Section 6.1, except as otherwise permitted in this Section 4.2(a), which Confidentiality Agreements shall be deemed by Sellers and Purchaser to cover the transactions contemplated by this Agreement. 18 After the Closing nothing contained in this Agreement or the Confidentiality Agreements shall restrict the right of Purchaser, as between Purchaser and any Seller, to use or disclose information regarding the Interests. Notwithstanding anything contained in this Section 4.2(a) to the contrary and insofar as it relates to the Interests, Purchaser may disclose any of the information subject to the first sentence of this Section 4.2(a) or covered by the Confidentiality Agreements to the extent (i) necessary to enforce, or seek redress for breach of, this Agreement, (ii) required by applicable law or the rules of a national securities exchange, (iii) necessary for financing, reserve engineering or accounting purposes, (iv) to comply with any law or legal process, or (v) otherwise previously made public (without breach of the preceding sentence of this Section 4.2(a) or of the Confidentiality Agreements). In addition, Seller acknowledges and agrees that Purchaser may issue one or more press releases and may make other public statements with respect to this Agreement or the transactions contemplated by this Agreement. If a proposed press release or other public statement will contain information not previously disclosed, Purchaser shall provide HHOC, pursuant to the Agreement and Plan of Merger referred to in clause (e) of Section 6.1, with any and all proposed forms of press release or other public statement and consult with HHOC before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated by this Agreement and shall not issue any such press release or make any such public statement prior to providing the proposed form of such press release or public statements and having such consultation; provided, however, that Purchaser may, without providing the proposed form of such press release or public statement or consulting with HHOC, issue such a press release or make such a public statement if required by applicable law or the rules of a national securities exchange if Purchaser has used reasonable efforts to provide HHOC with the proposed form of press release or public statement and consult with HHOC but has been unable to do so in a timely manner. (b) Purchaser shall remain qualified under applicable laws and regulations, including the rules and regulations of the MMS, to own and operate federal oil and gas leases in the Outer Continental Shelf, Gulf of Mexico and shall be, as of the Closing, in good standing with, and authorized and qualified by, all governmental agencies with jurisdiction or cognizance over operations on the Outer Continental Shelf, Gulf of Mexico. (c) Purchaser shall take or cause to be taken all reasonable actions within its control as may be necessary or advisable to consummate and make effective the purchase of the Interests and the transactions contemplated by this Agreement and to assure that, as of the Closing Date, it will not be under any material corporate, legal or contractual restriction that would prohibit or delay the timely consummation of such transactions. (d) Purchaser shall take or cause to be taken all reasonable actions to cause all the representations and warranties of Purchaser contained in this Agreement to be true and correct on and as of the Closing Date, other than such as are made as of a specific date. 19 (e) Purchaser shall notify each Seller promptly (i) upon learning of any change in fact or circumstance that causes any representation or warranty of Purchaser contained in this Agreement to no longer be accurate and complete or (ii) if Purchaser fails to perform or comply with any covenant or agreement contained in this Agreement or it is reasonably anticipated that Purchaser will be unable to perform or comply with any covenant or agreement contained in this Agreement. ARTICLE V REVIEW BY PURCHASER 5.1. Due Diligence. Purchaser may conduct, prior to the Closing and at its cost, such further review of data and information pertaining to the Interests and title examination and other examinations and investigations in respect of the Interests as Purchaser desires. 5.2. Access to Interests. Following the execution of this Agreement and until the Closing, Seller shall provide Purchaser and its representatives access to the Interests and the right to observe operations and inspect any and all of the Interests, the Equipment and improvements and fixtures included in the Interests, to the extent that such Seller has the legal right to grant such access and right. All visits by Purchaser or by others on behalf of Purchaser to any facilities associated with any of the Leases shall be scheduled by mutual consent of Purchaser and HHOC, subject to Purchaser providing to HHOC reasonable advance notice of the locations that Purchaser wishes to visit and the proposed times. Any Seller or HHOC may accompany Purchaser and its representatives during their site visits. Entry onto any Interest will be (i) subject to valid third-party restrictions, if any, existing under the terms of the Contracts, and to industrial safety, hygiene, and drug and alcohol requirements of any Seller or the relevant operator and (ii) at the sole risk and expense of Purchaser. Each Seller shall use reasonable efforts to arrange for Purchaser access to, and the right to observe operations on and inspect, any Interests requested by Purchaser with respect to which such Seller alone does not have the right to grant such access and rights. Each Seller shall use reasonable efforts to identify for Purchaser, upon request, any third-party restrictions to which Purchaser may be subject in exercising its rights to enter upon any of the Interests. PURCHASER AGREES TO PROTECT, INDEMNIFY, DEFEND AND HOLD HARMLESS EACH SELLER AND ITS CO-OWNERS, FARMORS AND CONTRACTORS, ITS AND THEIR RESPECTIVE SUBCONTRACTORS, AND ITS AND THEIR RESPECTIVE DIRECTORS, MANAGERS, OFFICERS, EMPLOYEES, AGENTS, REPRESENTATIVES AND INVITEES FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS AND DEMANDS IN CONNECTION WITH PERSONAL INJURIES, INCLUDING DEATH, AND PROPERTY DAMAGE ARISING OUT OF OR RELATING TO THE ACCESS OF PURCHASER AND ITS REPRESENTATIVES TO THE INTERESTS, THE EQUIPMENT AND IMPROVEMENTS AND FIXTURES INCLUDED IN THE INTERESTS. 5.3. Environmental Assessment. (a) Purchaser may conduct, prior to the Closing and at its cost, an environmental assessment of any of the Interests. 20 (b) PURCHASER ACKNOWLEDGES THAT PORTIONS OF THE INTERESTS MAY BE CONTAMINATED WITH NATURALLY OCCURRING RADIOACTIVE MATERIALS ("NORM"), AND, UPON THE CLOSING, PURCHASER HEREBY ACCEPTS, WITH RESPECT TO THE INTERESTS, FULL RESPONSIBILITY FOR COMPLYING WITH ALL LEGAL REQUIREMENTS APPLICABLE TO NORM. 5.4. Imbalances. Upon the occurrence of the Closing, but effective as of the Effective Time, Purchaser shall succeed to and assume the position of each Seller with respect to all Imbalances related to the Interests and described in Schedule 3.1(n). As a result of such succession, Purchaser shall be (i) entitled to receive any and all benefits which any Seller would have been entitled to receive by virtue of such position (including rights to produce and receive volumes of production in excess of volumes which it would otherwise be entitled to produce and receive by virtue of ownership of the Interests and rights to receive cash balancing payments), (ii) obligated to suffer any detriments which any Seller would have been obligated to suffer by virtue of such position (including the obligation to deliver to others production volumes which would have otherwise been attributable to its ownership of any of the Interests, to deliver production to purchasers thereof without receiving full payment therefor, or to make cash balancing payments or to repay take or pay payments) and (iii) responsible for any and all royalty obligations with respect to such Imbalances (including any of such arising out of royalties having been paid on an "entitlements" basis rather than a "receipts" basis). EACH SELLER, SEVERALLY AND NOT JOINTLY, SHALL PROTECT, DEFEND INDEMNIFY AND HOLD PURCHASER HARMLESS FROM AND AGAINST ANY OBLIGATIONS, LOSSES OR LIABILITIES ARISING OUT OF ANY IMBALANCES ALLOCABLE TO SUCH SELLER THAT EXIST ON THE EFFECTIVE TIME, OTHER THAN THOSE DESCRIBED IN SCHEDULE 3.1(N). 5.5. Defensible Title. (a) "Defensible Title" means such title and ownership of each Seller (pursuant to instruments filed with and, to the extent required, approved by the MMS and filed of record in the appropriate parish records or, in the case of those instruments not yet approved by the MMS or not in approvable form and listed in Schedule 3.1(a), pursuant to instruments filed with the MMS and filed of record in the appropriate parish record or, as to assignments to each Seller of those of the Interests of such Seller relating to East Cameron Block 196, pursuant to instruments in the possession of such Seller) that, in each case (i) will entitle Purchaser, as the successor to each Seller, to receive and retain, now and, except as the result of any action by Purchaser subsequent to the Closing, in the future, without suspension, reduction or termination, not less than the relevant Net Revenue Interest of such Seller listed in Schedule 1-A of Substances produced under the terms of the Leases (or other property denominated in Schedule 1-A) and the proceeds from the sale thereof through plugging, abandonment and salvage of all Wells comprising or included in such Interests of such Seller and all Wells now or hereafter producing from or attributable to such Interests of such Seller; (ii) will obligate Purchaser, as the successor to such Seller to bear, now and, except as the result of any action by Purchaser subsequent to the Closing, in the future, a percentage of costs and expenses related to the maintenance, operation and development of the Leases (or other property denominated in Schedule 1-A) not greater than 21 the relevant Working Interest of such Seller listed in Schedule 1-A, through plugging, abandonment and salvage of all Wells comprising or included in such Interests of such Seller and all Wells now or hereafter producing from or attributable to such Interests of such Seller, unless the circumstances causing the Working Interest of such Seller to be greater will cause the corresponding Net Revenue Interest of such Seller to increase in the same proportion; and (iii) is free of all claims, liens, security interests, encumbrances, irregularities and defects, except for Permitted Encumbrances (as defined below in this Section 5.5). (b) "Permitted Encumbrances" are: (i) lessor's royalties, overriding royalties, production payments, net profits interests, reversionary interests and similar burdens measured by or payable out of production of Substances or proceeds from the sale thereof and other obligations that, in any case, do not, and will not, reduce, now or, except as the result of any action by Purchaser subsequent to the Closing, in the future, the relevant Net Revenue Interest of Purchaser, as the successor in title to each Seller, below the relevant Net Revenue Interest of such Seller listed in Schedule 1-A or increase, now or, except as the result of any action by Purchaser subsequent to the Closing, in the future, the relevant Working Interest of Purchaser, as the successor in title to each Seller, above the relevant Working Interest of such Seller listed in Schedule 1-A (unless the circumstance causing such Working Interest of such Seller to increase will cause the corresponding Net Revenue Interest of such Seller to increase at least in the same proportion); (ii) third-party consents which are obtained prior to the Closing from the appropriate persons or entities; (iii) mechanics', materialmen's, operator's and non-operators', tax and similar liens or charges arising in the ordinary course of business related to an Interest, if such liens or charges secure payments not yet due; (iv) all consents from, notices to, approvals by or other actions by any governmental authority in connection with the sale or transfer of the Interests of any Seller by such Seller to Purchaser pursuant to this Agreement if such matters are customarily and appropriately obtained after the sale or transfer; (v) rights of a governmental entity to control or regulate the Interests, together with all applicable laws, rules and regulations; (vi) easements, rights-of-way, surface leases and other surface use restrictions if such restrictions will not materially adversely affect the use, value or operation of the Interests; and 22 (vii) to the extent not included in any of the foregoing clauses (i) - (vii), the Contracts. 5.6. Casualty Loss. If, subsequent to the execution of this Agreement but prior to the Closing, all or any portion of an Interest is damaged or destroyed (each such instance a "Casualty Loss"), this Agreement shall remain in full force and effect notwithstanding any such damage or destruction. Purchaser may, to the extent insurance proceeds are not committed, used or applied prior to the Closing Date to repair, restore or replace such damaged Interests, require each Seller, at the Closing, to (i) assign to Purchaser the right of such Seller to receive all insurance proceeds owed to such Seller by reason of such Casualty Loss, less any reasonable costs and expenses incurred by such Seller in collecting such proceeds and (ii) pay to Purchaser all insurance proceeds theretofore paid to such Seller by reason of such destruction, less any reasonable costs and expenses incurred by such Seller in collecting such proceeds. Notwithstanding the foregoing, any insurance proceeds (or any rights thereto) by reason of any Casualty Loss which are held by or owed to any Seller for the account or benefit of any third party joint interest owners shall not be paid or assigned by such Seller to Purchaser pursuant to this Section 5.6 but shall instead be transferred to the successor operator or other party responsible therefor pursuant to the terms of the applicable operating or other agreement. No Seller shall compromise or settle a Casualty Loss without the consent of Purchaser. 5.7. No Warranty of Merchantability or Fitness. Except as otherwise specifically set forth in this Agreement, no Seller makes any warranties, express or implied, including the warranty of merchantability and the implied warranty of fitness for a particular purpose, regarding the Equipment and other like personal property located on or included in the Interests of any Seller and such are to be sold on an "as is, where is", basis and condition.

ARTICLE VIII TERMINATION 8.1. Termination. This Agreement and the transactions contemplated by this Agreement may be terminated in the following situations: (a) by Sellers or Purchaser, if the Merger Agreement shall have terminated in accordance with its terms; and (b) by Sellers and Purchaser pursuant to written agreement. 8.2. Liabilities Upon Termination. (a) Notwithstanding anything provided to the contrary in this Agreement, upon the failure by Purchaser to fulfill any undertaking or commitment provided for herein on the part of Purchaser that is required to be fulfilled on or prior to the Closing Date, each Seller, at its sole option, shall be entitled to any remedy available at law or in equity. (b) Notwithstanding anything provided to the contrary in this Agreement, upon failure of Sellers to fulfill any undertaking or commitment provided for herein on the part of Sellers that is required to be fulfilled on or prior to the Closing Date, Purchaser, at its sole option, shall be entitled to any remedy available at law or in equity. (c) NOTWITHSTANDING ANYTHING CONTAINED TO THE CONTRARY IN ANY OTHER PROVISION OF THIS AGREEMENT, SELLERS AND PURCHASER AGREE THAT THE RECOVERY BY EITHER PARTY HERETO OF ANY DAMAGES SUFFERED OR INCURRED BY IT AS A RESULT OF ANY BREACH BY THE OTHER PARTY OF ANY OF ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS UNDER THIS AGREEMENT SHALL BE LIMITED TO THE ACTUAL DAMAGES SUFFERED OR INCURRED BY THE NON-BREACHING PARTY AS A RESULT OF THE BREACH BY THE BREACHING PARTY OF ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS HEREUNDER, AND IN NO EVENT SHALL THE BREACHING PARTY BE LIABLE TO THE NON-BREACHING PARTY FOR ANY INDIRECT, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES SUFFERED OR INCURRED BY THE NON-BREACHING PARTY AS A RESULT OF THE BREACH BY THE BREACHING PARTY OF ANY OF ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS HEREUNDER. ARTICLE IX OBLIGATIONS AFTER CLOSING 27 9.1. Post-Closing Adjustments. As soon as practicable after the Closing, but in any event within ninety (90) days after the Closing, Purchaser shall cause HHOC to prepare and submit to each Seller a statement, substantially in the form of Exhibit A (the "Final Settlement Statement"), containing adjustments to the Purchase Price contemplated by the provisions of Section 2.2 and the resulting Adjustment Amount for each Seller, together with such supporting documentation as is reasonably necessary to support the adjustments shown therein. Purchaser shall cause HHOC to give representatives of each Seller reasonable access to the premises of HHOC and to the books and records of HHOC for purposes of reviewing the calculation of any such adjustments and will cause appropriate personnel of HHOC to assist each Seller and representatives of any Seller, at no cost to such Seller, in verification of such calculations. The Final Settlement Statement shall become final and binding on Sellers and Purchaser as to the calculation of the Adjusted Purchase Price forty five (45) days following the date the Final Settlement Statement is received by Sellers, except to the extent that, prior to the expiration of such forty five (45) day period, any Seller shall deliver to Purchaser notice, as hereinafter required, of its disagreement with the contents of the Final Settlement Statement. Such notice shall be in writing and set forth all disagreements of any Seller with respect to any portion of the Final Settlement Statement, together with any changes thereto proposed by such Seller, and shall include an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary to support, such changes. If any Seller has timely delivered such a notice of disagreement to Purchaser, then, upon written agreement between Purchaser and Sellers resolving all disagreements set forth in such notice, the Final Settlement Statement shall become final and binding upon Purchaser and Sellers as to the calculation of the Adjusted Purchase Price. If the Final Settlement Statement has not become final and binding by the seventy fifth (75th) day following its receipt by Sellers, then Purchaser or Sellers may submit to a nationally-recognized firm of certified public accountants which neither serves as the auditors for nor provides consulting services to HHOC or any Sellers or Purchaser or such other independent public accounting firm mutually satisfactory to Sellers and Purchaser for resolution any unresolved disagreements of Sellers set forth in the notice from Sellers to Purchaser. The fees and expenses of such accounting firm in making such determination shall be shared equally by Purchaser, on the onehand, and Sellers, on the other. Upon resolution of such unresolved disagreements of Purchaser, the Final Settlement Statement (including any revisions thereto as are so resolved or agreed) shall be conclusive, final and binding upon Purchaser and Sellers as to the calculation of the Adjusted Purchase Price. Payment of any net amount due to Sellers or Purchaser, as the case may be, on the basis thereof shall be made within five (5) days after the Final Settlement Statement (as so resolved or agreed) becomes final and binding on the parties hereto (the "Final Settlement Date"). 9.2. Subsequent Adjustments. Sellers and Purchaser recognize that either Sellers or Purchaser may receive funds or pay expenses after the Final Settlement Date which are properly the property or obligation of the other. Upon receipt of net proceeds or payment of net expenses due to or payable by the other party hereto, whichever occurs first, Sellers or Purchaser, as the case may be, shall submit a statement to the other party hereto showing the relevant items of 28 income and expense. Payment of any net amount due by Sellers or Purchaser, as the case may be, on the basis thereof shall be made within ten (10) days of receipt of the statement. 9.3. Reservation of Claims. Except as provided in this Agreement, each Seller is entitled to all claims related to the Interests of such Seller prior to the Effective Time regardless of when payment is made. Except as provided in this Agreement, Purchaser is entitled to all claims related to the Interests which arise after the Effective Time. 9.4. Files and Records. Upon the Closing, subject to the provisions of Section 1.2(f), Sellers shall permit Purchaser, at the expense of Purchaser, to take possession of originals, or with respect to accounting records relating to periods prior to the Closing Date, copies, of all Records in the possession or control of any Seller or HHOC and relating to the Interests. Each Seller shall have the right to copy (at the expense of such Seller) and retain a copy of all such files, records and data. Insofar as any Seller reasonably believes such Records may be needed or useful in connection with federal, state or local regulatory or tax matters or resolution of existing disputes or contract compliance issues with third parties or for any other appropriate purposes, such Seller shall have the right to make, at the expense of such Seller, and retain copies of Records subsequent to the delivery of such Records to Purchaser; provided, however, any such copies of Records retained by such Seller shall be confidential and proprietary to Purchaser to the extent the relevant Records were theretofore maintained as such by such Seller, and to such extent and except as provided herein to the contrary, such Seller may not divulge any matters contained therein or any other information provided by Purchaser to such Seller pursuant to the terms of this Agreement, without the prior express written consent of Purchaser, except (a) as required by applicable law, (b) as required by order of any court, (c) to the extent otherwise previously made public (other than by disclosure in breach of this Agreement) or (d) as is necessary to enforce, or seek redress for breach of, this Agreement. Except as may be otherwise required by any of the Contracts or applicable law, Purchaser shall be obligated to maintain the Records for a period of seven years following the Closing Date; provided, however, Purchaser shall not be obligated to maintain any Records that relate in all material respects to any of the Interests that cease to be owned by Purchaser if Purchaser has obligated its successors and assigns of such Records to maintain and allow access to such Records for the remainder of such seven-year period; and provided further, however, Purchaser shall not be required to retain any Records that it has offered to deliver to Sellers. 9.5. Further Assurances. After the Closing, Sellers and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary or advisable to carry out their obligations under this Agreement or any other document delivered pursuant hereto. In particular, Sellers and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary and advisable to (a) make all filings, registrations, and recordings which must be made with respect to the Leases in the records of the MMS and all appropriate counties, parishes, and state agencies and offices in order that the records maintained by the MMS and the appropriate state agencies and the appropriate records of the relevant parishes and counties shall accurately reflect the transfer of the Interests to Purchaser, (b) enable 29 Sellers to take promptly all actions over which Sellers have control to allow Purchaser to be designated as the operator with respect to those Interests as to which any Seller or HHOC is the operator as of the Effective Time, and (c) obtain prompt and unconditional approvals of transfers of the Leases by the MMS. To the extent required by the MMS, Purchaser agrees to take promptly any and all actions necessary to post with the MMS any supplemental bonds and provide any and all documentation that may be required by the MMS to evidence the financial responsibility of Purchaser under applicable federal regulations and MMS policies. 9.6. Assumption and Indemnity. (a) Upon the Closing, Purchaser hereby assumes responsibility for and agrees to pay, perform and discharge all of the following (collectively, the "Assumed Obligations"): (i) all duties and obligations of Sellers arising out of or in connection with the ownership or operation of the Interests on or after the Closing Date, including (A) all costs, expenses, liabilities, claims and obligations assumed or otherwise agreed to be paid by Purchaser pursuant to the terms of this Agreement, excluding, however, any Environmental Liabilities (as defined below in this Section 9.6(a), such Environmental Liabilities, to the extent assumed by Purchaser, being exclusively addressed in clause (ii) below in this Section 9.6(a) and (B) all obligations regarding site clearance, plugging, abandoning, and removing all existing and any future Wells, platforms, facilities and pipelines located on or used in connection with the Interests in accordance with the requirements of all applicable governmental authorities and the terms of all applicable Leases and Contracts (such obligations in this clause (B) being the "Abandonment and Clean-up Obligations"); (ii) all Environmental Liabilities (as defined below in this Section 9.6(a)), whether accruing prior to, on or after the Closing Date; and (iii) the prompt and complete payment, performance and discharge of all obligations and liabilities of Sellers attributable to or arising out of any of the Leases and any of the Contracts listed on Schedule 1-C (the "Assumed Contracts") for the period from and after the Closing, to the extent such liabilities and obligations are (A) attributable to or arise out of the ownership, use or operation of the Interests, (B) attributable to the period of time on or after the Closing Date, and (C) are not the result of any default of or failure to perform by any Seller under any of the Assumed Contracts as to any point in time prior to the Closing; provided, however, notwithstanding anything contained in clauses (i), (ii) or (iii) of this Section 9.6(a) to the contrary, Purchaser shall not assume and shall have no liability (contingent or otherwise) whatsoever with respect to the Retained Obligations (as defined in Section 9.6(b)) or any matter 30 with respect to which any Seller has indemnified Purchaser pursuant to clause (ii) of Section 9.6(d). (a) The term "Environmental Liabilities," as used herein, shall mean all costs, expenses, liabilities, and obligations attributable to the Interests and arising out of or in connection with any violation of Environmental Laws or any Environmental Non-Violation of Laws Matters (as defined below in this Section 9.6(a). The term "Environmental Non-Violation of Laws Matters," as used herein, shall mean any cost, expense, liability or obligation with respect to the Interests (x) resulting from or attributable to actual, threatened, or alleged emissions, discharges, or releases of Hazardous Substances (as defined below in this Section 9.6(a)) into ambient air, surface water, groundwater or land, (y) resulting from or attributable to the manufacture, processing, distribution, use, treatment, storage, disposal, transport, or handling of Hazardous Substances, or (z) otherwise arising under or related to Environmental Laws. The term "Hazardous Substances" shall have the meaning given such term in the Comprehensive Environmental, Response, Compensation, and Liability Act of 1980. (b) Each Seller, severally and not jointly, shall retain responsibility for and agrees to pay, perform and discharge all costs, expenses, liabilities, claims and obligations (excluding, however, Abandonment and Clean-up Obligations, Environmental Liabilities) arising out of or in connection with the ownership or operation of the Interests of such Seller prior to the Closing Date (the "Retained Obligations"). (c) To the extent Purchaser wishes to make adjustments to any audits with respect to any of the Interests relating to any period prior to the Effective Time, Purchaser shall do so only with the prior written consent of any affected Seller.

PEPER UNDER THIS SECTION 9.6 (SUCH SELLERS BEING THE "GARY HALL GROUP") SHALL BE JOINT AMONG THEM, AS WELL AS SEVERAL) SHALL PROTECT, DEFEND, RELEASE, INDEMNIFY AND HOLD HARMLESS PURCHASER AND THE SHAREHOLDERS, DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS OF PURCHASER AND THE HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS, AND ASSIGNS OF ANY OF THE FOREGOING (EACH A "PURCHASER INDEMNIFIED PARTY") FROM ANY DAMAGES WHICH MAY BE ALLEGED AGAINST ANY PURCHASER INDEMNIFIED PARTY, ARISING OR ACCRUING WITH RESPECT TO (A) ANY REPRESENTATION OR WARRANTY (OTHER THAN ANY BREACH OF A REPRESENTATION OR WARRANTY BY SUCH SELLER AS TO COMPLIANCE WITH ENVIRONMENTAL LAWS OR ENVIRONMENTAL PERMITS OR THE EXISTENCE OF ABANDONMENT AND CLEAN-UP OBLIGATIONS OR ENVIRONMENTAL LIABILITIES) MADE BY SUCH SELLER IN OR PURSUANT TO THIS AGREEMENT BEING UNTRUE OR INCORRECT IN ANY MATERIAL RESPECT, (B) ANY FAILURE BY SUCH SELLER TO PERFORM ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT EXECUTED BY IT IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR (C) THE RETAINED OBLIGATIONS OF SUCH SELLER.

(e) Neither any Seller Indemnified Party nor any Purchaser Indemnified Party shall be entitled to indemnification under this Section 9.6 unless the aggregate of all amounts for which indemnity would otherwise be due to the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, exceeds $250,000 in the aggregate, in which case the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, shall be entitled to recover in full with respect to all such amounts. This threshold does not apply to (and shall not be satisfied by) defaults related to the payment of money or other liquidated amounts. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL PURCHASER OR ANY SELLER BE LIABLE HEREUNDER FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, STATUTORY, REMOTE OR SPECULATIVE DAMAGES. FURTHER NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, EXCEPT AS TO THE MEMBERS OF THE GARY HALL GROUP, THE LIABILITY OF EACH OF WHICH UNDER THIS SECTION 9.6 SHALL NOT EXCEED THE SUM OF THE VALUE OF THE CONSIDERATION RECEIVED BY ALL SUCH SELLERS HEREUNDER DETERMINED AS PROVIDED BELOW IN THIS SECTION 9.6, NO SELLER SHALL BE OBLIGATED TO PROVIDE INDEMNIFICATION UNDER THIS SECTION 9.6 EXCEEDING IN THE AGGREGATE AS TO ALL CLAIMS FOR SUCH INDEMNIFICATION, AN AMOUNT EQUAL TO THE VALUE OF THE CONSIDERATION RECEIVED BY SUCH SELLER HEREUNDER DETERMINED AS PROVIDED BELOW IN THIS SECTION 9.6. FOR PURPOSES OF THE FOREGOING SENTENCE, THE VALUE OF THE CONSIDERATION RECEIVED BY EACH SELLER SHALL BE THE SUM OF THE BUYER WARRANTS RECEIVED BY SUCH SELLER (VALUED AT $0.75 PER BUYER WARRANT) AND THE EARNOUT PAYMENTS ACTUALLY MADE TO SUCH SELLER. TO THE EXTENT ANY CLAIM AGAINST A SELLER UNDER THIS SECTION 9.6 EXCEEDS THE THEN EXISTING MAXIMUM LIABILITY OF SUCH SELLER UNDER THIS SECTION 9.6, PURCHASER SHALL 32 HAVE THE RIGHT TO SET OFF ANY SUCH UNSATISFIED CLAIM AGAINST FUTURE EARNOUT PAYMENTS DUE TO SUCH SELLER. SIMILARLY, NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, PURCHASER SHALL NOT BE OBLIGATED TO PROVIDE INDEMNIFICATION UNDER THIS SECTION 9.6 TO ANY SELLER AND ITS RELATED SELLER INDEMNIFIED PARTIES EXCEEDING IN THE AGGREGATE AN AMOUNT EQUAL TO THE MAXIMUM LIABILITY OF THE RELEVANT SELLER UNDER THIS SECTION 9.6. 9.7 Express Negligence. THE DEFENSE, INDEMNIFICATION AND HOLD HARMLESS PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE DAMAGES IN QUESTION AROSE SOLELY OR IN PART FROM THE ACTIVE, PASSIVE OR CONCURRENT NEGLIGENCE, OR OTHER FAULT (INCLUDING STRICT LIABILITY), OF ANY SELLER INDEMNIFIED PARTY OR PURCHASER INDEMNIFIED PARTY. PURCHASER AND EACH SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS. 9.8. Indemnification Procedure. All claims for indemnification under the provisions of Section 9.6 shall be asserted and resolved pursuant to the provisions of this Section 9.8. Any person or entity claiming indemnification hereunder is hereinafter referred to as the "Indemnified Party" and any person or entity against whom such claims are asserted hereunder is hereinafter referred to as the "Indemnifying Party." In the event that any Damages are asserted against or sought to be collected from an Indemnified Party by a third party, such Indemnified Party shall, with reasonable promptness, provide to the Indemnifying Party a written notice of claim specifying, in reasonable detail, the specific nature of and specific basis of the Damages and the estimated amount of such Damages and including a copy of all papers served with respect to such claim (if any) and the basis of such claim for indemnification under the provisions of Section 9.6 (each a "Claim Notice"). Notwithstanding the preceding sentence, failure of an Indemnified Party to give notice hereunder shall not release the Indemnifying Party from its obligations under the provisions of Section 9.6, except to the extent the Indemnifying Party is actually prejudiced by such failure to give notice; provided that, the Indemnifying Party shall not be obligated to defend, indemnify or otherwise hold harmless an Indemnified Party with respect to a third party claim until a Claim Notice meeting the foregoing requirements is furnished to the Indemnifying Party by the party seeking indemnity hereunder. The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of any Claim Notice (the "Notice Period") in which to notify the Indemnified Party whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Damages. If the Indemnifying Party fails to so notify the Indemnified Party during the Notice Period, the Indemnifying Party shall be deemed to have elected to dispute such liability. The Indemnified Party shall have the duty to defend such third party claim by all appropriate proceedings, and with counsel of its own choosing, which proceedings shall be promptly settled or prosecuted to a final conclusion. If the Indemnifying Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. If requested by the Indemnified Party, the Indemnifying Party agrees to cooperate with the Indemnified Party and its counsel in contesting any Damages that the Indemnified Party elects to contest. No claim may be settled or otherwise compromised 33 without the prior written consent of the Indemnifying Party. If the Indemnifying Party disputes whether a third party claim is an indemnified claim under the provisions of Section 9.6, the determination of whether the Indemnified Party is entitled to indemnification under the provisions of Section 9.6 shall be resolved pursuant to arbitration as provided in Section 10.16. 9.9 Allocation of Proceeds. Sellers shall receive all proceeds from the sale of Substances physically produced or allocable to the Interests prior to the Effective Time. Purchaser shall receive all proceeds from the sale of Substances physically produced or allocable to the Interests on or after the Effective Time. 9.10. Termination of Confidentiality Agreements. Effective upon the Closing, the obligations of Purchaser under the Confidentiality Agreements, insofar and only insofar as they relate to the Interests, are terminated. ARTICLE X MISCELLANEOUS 10.1. Notices. All notices required or permitted under this Agreement shall be effective upon receipt if personally delivered, if mailed by registered or certified mail, postage prepaid, or if delivered by telegram, telecopy or facsimile if directed to the relevant party hereto as follows: To any Seller: [Name of relevant Seller] c/o Hall-Houston Oil Company 700 Louisiana, Suite 2100 Houston, Texas 77002 Telephone: (713) 228-0711 Fax: (713) 225-7600 Attn: John H.

Any party hereto may give written notice to the others, in the aforesaid manner, of a change in the address or individual to whom delivery to such party shall be made. 10.2 Expenses. Except as otherwise provided in this Agreement, all fees, costs and expenses incurred by any party hereto in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the party hereto incurring them. 10.3. Amendment. This Agreement may not be altered or amended, nor may any rights hereunder be waived, except by a written instrument executed by each of the parties hereto. No waiver of any provision of this Agreement shall be construed as a continuing waiver of the same provision or of any other provision of this Agreement. 10.4. Assignment. Except as provided in the following sentence of this Section 10.4, neither party hereto may assign or delegate any of its rights or duties hereunder without the prior written consent of the other party hereto. Purchaser shall have the right, without obtaining the prior written consent of Sellers, to assign the rights of Purchaser hereunder to HHOC or an Affiliate (as defined below in this Section 10.4) of Purchaser; provided, however, no such assignment shall relieve Purchaser of any of its obligations under this Agreement. In connection with any such assignment by Purchaser to HHOC made prior to the Closing, Sellers agree to enter into an amendment to this Agreement, in form mutually satisfactory to Sellers and HHOC and approved by Purchaser, substituting shares of a new series of preferred stock of HHOC (the "New HHOC Preferred Stock") as the purchase price to be paid for the Interests, amending the provisions of Section 2.3 and Section 7.2 accordingly, and committing Sellers, in connection with the closing of the merger which is the subject of the Merger Agreement, to exchange such shares of the New HHOC Preferred Stock for the Securities Consideration and the Earnout Consideration as set forth in Section 2.1, which shall be allocable among Sellers as set forth in Schedule 2.1. The term "Affiliate" as used herein shall mean, as to the person or entity specified, any person or entity controlling, controlled by or under common control with such specified person or entity. The concept of control, controlling or controlled by as used in the aforesaid context means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of another, whether through the ownership of voting securities, by contract or otherwise. No person or entity shall be deemed an Affiliate of any person or entity by reason of the exercise or existence of rights, interests or remedies under this Agreement. 10.5. Conditions. The inclusion in this Agreement of conditions to the obligations of each Seller or Purchaser at the Closing shall not, in and of itself, be a covenant of any party hereto to satisfy the conditions to the obligations of any other party hereto at the Closing. 10.6. References. References in this Agreement to Schedule, Exhibit, Article, or Section numbers shall be to Schedules, Exhibits, Articles, or Sections of this Agreement, unless 35 expressly stated to the contrary. References in this Agreement to "hereby," "herein," "hereinafter," "hereinabove," "hereinbelow," "hereof," "hereunder" and words of similar import shall be to this Agreement in its entirety and not only to the particular Schedule, Exhibit, Article, or Section in which such reference appears. Specific enumeration herein shall not exclude the general and, in such regard, references in this Agreement to "includes" or "including" shall mean "includes, without limitation," or "including, without limitation," as the case may be. Except as otherwise indicated, references in this Agreement to statutes, sections, or regulations are to be construed as including all statutory or regulatory provisions consolidating, amending, replacing, succeeding, or supplementing the statute, section, or regulation referred to. References in this Agreement to "writing" include printing, typing, lithography, facsimile reproduction, and other means of reproducing words in a tangible visible form. References in this Agreement to agreements and other contractual instruments shall be deemed to include all exhibits and appendices attached thereto and all subsequent amendments and other modifications to such instruments, but only to the extent such amendments and other modifications are not prohibited by the terms of this Agreement. References in this Agreement to persons or entities include their respective successors and permitted assigns. 10.7. Articles and Sections. This Agreement, for convenience only, has been divided into Articles and Sections; and it is understood that the rights and other legal relations of the parties hereto shall be determined from this instrument as an entirety and without regard to the aforesaid division into Articles and Sections and without regard to headings prefixed to such Articles or Sections. 10.8. Number and Gender. Whenever the context requires, reference herein made to the single number shall be understood to include the plural; and likewise, the plural shall be understood to include the singular. Definitions of terms defined in the singular or plural shall be equally applicable to the plural or singular, as the case may be, unless otherwise indicated. Words denoting sex shall be construed to include the masculine, feminine and neuter, when such construction is appropriate; and specific enumeration shall not exclude the general but shall be construed as cumulative. 10.9. Incorporation of Schedules and Exhibits. The Schedules and Exhibits attached to this Agreement are incorporated herein and shall be considered a part of this Agreement for all purposes. 10.10. Counterparts. This Agreement may be executed in counterparts, each of which shall be an original and which, taken together, shall constitute the same instrument. 10.11. Governing Law. EXCEPT TO THE EXTENT THE LAWS OF ANOTHER JURISDICTION MANDATORILY GOVERN ANY ASPECT OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE 36 STATE OF LOUISIANA, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF SUCH LAWS REGARDING CONFLICT OF LAWS. 10.12. Integration. THIS AGREEMENT AND THE DOCUMENTATION TO BE EXECUTED AND DELIVERED AT THE CLOSING CONSTITUTE THE ENTIRE UNDERSTANDING BETWEEN SELLER AND PURCHASER CONCERNING THE SUBJECT MATTER OF THIS AGREEMENT AND SUPERSEDE ALL NEGOTIATIONS, DISCUSSIONS, REPRESENTATIONS, PRIOR AGREEMENTS AND UNDERSTANDINGS, WHETHER ORAL OR WRITTEN, EXCEPT THE CONFIDENTIALITY AGREEMENT. 10.13. Parties in Interest. Except as otherwise expressly provided herein, this Agreement is binding upon and shall inure to the benefit of Seller and Purchaser and their respective successors, representatives, and permitted assigns. Except as otherwise expressly provided herein, no other person or entity is intended to have any benefits, rights or remedies under this Agreement nor shall any person or entity other than Purchaser and Seller be entitled to any claim, cause of action, remedy, or right of any kind under this Agreement. 10.14. Severability. If any provision of this Agreement is found to be illegal or unenforceable, the other terms of this Agreement shall remain in effect and this Agreement shall be construed as if the illegal or unenforceable provision had not been included. 10.15. Survival. The covenants, agreements, representations, warranties and indemnities contained in this Agreement shall survive the Closing of the transactions contemplated hereby; provided, however, except as to the representations and warranties made by each Seller in Sections 3.1(a), (b), (c), (d) and (e), the representations and warranties made by each Seller in this Agreement and indemnities by each Seller associated therewith shall survive the Closing for eighteen months only. 10.16. Arbitration. Except as provided in Section 9.1 and below in this Section 10.16, any dispute, controversy or claim arising out of or in relation to or in connection with this Agreement, including any dispute as to the construction, validity, interpretation, enforceability or breach of this Agreement, shall be exclusively and finally settled by arbitration in accordance with this Section 10.16. Any party may submit such a dispute, controversy or claim to arbitration by notice to the other involved party and the administrator for the American Arbitration Association ("AAA"). The arbitration proceedings shall be conducted in New Orleans, Louisiana, in accordance with the Commercial Arbitration Rules of the American Arbitration Association as in effect on the date hereof. The arbitration shall be heard and determined by three arbitrators. Each side shall appoint an arbitrator of its choice within twenty (20) days of the submission of the notice of arbitration. The party-appointed arbitrators shall in turn appoint a presiding arbitrator for the tribunal within twenty (20) days following the appointment of the second party-appointed arbitrator. If the party-appointed arbitrators cannot reach agreement on a presiding arbitrator for the tribunal and/or one party fails to appoint its party-appointed arbitrator within the applicable period, the AAA shall act as appointing authority to appoint an independent 37 arbitrator with at least ten (10) years experience in the legal and/or commercial aspects of the petroleum exploration and production industry. None of the arbitrators shall have been an employee or consultant to either party to the arbitration or any of their respective Affiliates, or have any financial interest in the dispute, controversy or claim. All decisions of the arbitral tribunal shall be by majority vote. The arbitrators may not award consequential, punitive or similar damages except those claimed by persons other than Sellers and Purchaser for which responsibility is being allocated among the parties. Expenses in connection with the arbitration and the compensation and expenses of the arbitrators shall be borne in such manner as may be specified in the arbitral award. Privileges protecting attorney-client communications and attorney work product from compelled disclosure or use in evidence, as recognized by the Federal Rules of Civil Procedure, shall apply to and be binding in any arbitration proceeding conducted under this Section 10.16. This Section 10.16 does not apply to any dispute, controversy or claim in which the claimant seeks injunctive, declaratory or other equitable relief, and each party hereto reserves its right to bring such action in court, which the parties hereto agree shall be exclusively the U.S. Federal Courts sitting in the Eastern District of Louisiana and each party hereto irrevocably consents to personal jurisdiction in any and all such tribunals.

(k) No representation or warranty of Purchaser contained in this Agreement and no statement contained in any certificate or schedule furnished or to be furnished by or on behalf of Purchaser or any of its representatives pursuant thereto contains or will contain any untrue statement of a material fact, or omits or will omit to state any material fact necessary, in light of the circumstances under which it was or will be made, in order to make the statements herein or therein not misleading or necessary in order to fully and fairly provide the information required to be provided in any such document, certificate or schedule. ARTICLE IV COVENANTS 4.1. Covenants of Seller. Each Seller, severally and not jointly, covenants and agrees with Purchaser as follows: (a) Following execution of this Agreement and until the Closing, such Seller shall (i) notify Purchaser of any suit, arbitration, inquiry, proceeding, audit, claim, demand or investigation becoming known to such Seller which might adversely affect any of the Interests of such Seller and (ii) use reasonable efforts to obtain any consents, waivers, and approvals required of third persons, governmental authorities or other entities in connection with consummation of the transactions contemplated by this Agreement. (b) Following execution of this Agreement, such Seller shall not, without the consent of Purchaser (i) create a lien, security interest or other encumbrance on any of the Interests of such Seller; (ii) sell or dispose of any of the Interests of such Seller, other than Substances sold, consumed or produced in the ordinary course of business; or (iii) waive, compromise or settle any claim that diminishes or adversely burdens any Interest of such Seller. (c) Following the execution of this Agreement and until the Closing, such Seller shall provide Purchaser and its attorneys, employees, accountants, engineers, consultants and agents (collectively "representatives") access, during normal business hours and at the offices of HHOC, to (and the right to copy, at the expense of Purchaser) the records pertaining to the ownership of the Interests of such Seller (including title files and production, severance and ad valorem tax records), insofar as any of such are in the possession or control of such Seller or HHOC or insofar as such Seller or HHOC has access thereto, and to the extent, in each case, that such Seller or HHOC may do so without violating legal constraints or any legal obligation, for the purpose of the conducting, by or at the direction of Purchaser, of due diligence reviews of the Interests of such Seller. Subsequent to the Closing, such Seller shall cooperate with Purchaser in any efforts by Purchaser to obtain (at the expense of Purchaser) such additional title information as Purchaser may reasonably require. (d) At or prior to the Closing, with respect to matters that are not Permitted Encumbrances (as defined in Section 5.2), such Seller shall cause the owners and holders of any -8- liens, security interests and other encumbrances filed of record against any of the Interests of such Seller to execute and deliver such releases and other instruments, in form and substance reasonably satisfactory to Purchaser, as shall be necessary or appropriate to release of record, or to the extent not of record, known to such Seller, all liens, security interests, and other encumbrances filed against any of the Interests of such Seller. (e) Such Seller shall take or cause to be taken all reasonable actions within its control as may be necessary or advisable to consummate and make effective the purchase of the Interests of such Seller and the transactions contemplated by this Agreement and to assure that, as of the Closing Date, it will not be under any material organizational, legal or contractual restriction that would prohibit or delay the timely consummation of such transactions. (f) Such Seller shall take or cause to be taken all reasonable actions to cause all the representations and warranties of such Seller contained in this Agreement to be true and correct on and as of the Closing Date, other than those as are made as of a specific date. To the extent the conditions precedent to the obligations of Purchaser are within the control of such Seller, such Seller shall cause such conditions to be satisfied on or prior to the Closing Date and, to the extent the conditions precedent to the obligations of Purchaser are not within the control of such Seller, such Seller shall take or cause to be taken all such commercially reasonable actions as may be necessary to cause such conditions to be satisfied on or prior to the Closing Date. (g) Such Seller shall notify Purchaser promptly (i) upon learning of any change in fact or circumstance that causes any representation or warranty of such Seller contained in this Agreement to no longer be accurate and complete or (ii) if such Seller fails to perform or comply with any covenant or agreement contained in this Agreement or it is reasonably anticipated that such Seller will be unable to perform or comply with any covenant or agreement contained in this Agreement. 4.2. Covenants of Purchaser. Purchaser agrees with each Seller as follows: (a) Until the Closing, Purchaser shall comply with the Confidentiality Agreements (as such term is defined in the Agreement and Plan of Merger referred to in clause (e) of Section 6.1), except as otherwise permitted in this Section 4.2(a), which Confidentiality Agreements shall be deemed by Sellers and Purchaser to cover the transactions contemplated by this Agreement. After the Closing nothing contained in this Agreement or the Confidentiality Agreements shall restrict the right of Purchaser, as between Purchaser and any Seller, to use or disclose information regarding the Interests. Notwithstanding anything contained in this Section 4.2(a) to the contrary and insofar as it relates to the Interests, Purchaser may disclose any of the information subject to the first sentence of this Section 4.2(a) or covered by the Confidentiality Agreements to the extent (i) necessary to enforce, or seek redress for breach of, this Agreement, (ii) required by applicable law or the rules of a national securities exchange, (iii) necessary for financing, reserve engineering or accounting purposes, (iv) to comply with any law or legal process, or (v) otherwise previously made public (without breach of the preceding sentence of this Section 4.2(a) or of the Confidentiality Agreements). In addition, each Seller acknowledges and agrees that Purchaser may issue one or more press releases and may make other public statements with respect to this Agreement or -9- the transactions contemplated by this Agreement. If a proposed press release or other public statement will contain information not previously disclosed, Purchaser shall provide HHOC, pursuant to the Agreement and Plan of Merger referred to in clause (e) of Section 6.1, with any and all proposed forms of press release or other public statement and consult with HHOC before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated by this Agreement and shall not issue any such press release or make any such public statement prior to providing the proposed form of such press release or public statements and having such consultation; provided, however, that Purchaser may, without providing the proposed form of such press release or public statement or consulting with HHOC, issue such a press release or make such a public statement if required by applicable law or the rules of a national securities exchange if Purchaser has used reasonable efforts to provide HHOC with the proposed form of press release or public statement and consult with HHOC but has been unable to do so in a timely manner. (b) Purchaser shall take or cause to be taken all reasonable actions within its control as may be necessary or advisable to consummate and make effective the purchase of the Interests and the transactions contemplated by this Agreement and to assure that, as of the Closing Date, it will not be under any material corporate, legal or contractual restriction that would prohibit or delay the timely consummation of such transactions. -14- (c) Purchaser shall take or cause to be taken all reasonable actions to cause all the representations and warranties of Purchaser contained in this Agreement to be true and correct on and as of the Closing Date, other than such as are made as of a specific date. (d) Purchaser shall notify each Seller promptly (i) upon learning of any change in fact or circumstance that causes any representation or warranty of Purchaser contained in this Agreement to no longer be accurate and complete or (ii) if Purchaser fails to perform or comply with any covenant or agreement contained in this Agreement or it is reasonably anticipated that Purchaser will be unable to perform or comply with any covenant or agreement contained in this Agreement. ARTICLE V REVIEW BY PURCHASER 5.1. Due Diligence. Purchaser may conduct, prior to the Closing and at its cost, such further review of data and information pertaining to the Interests and title examination and other examinations and investigations in respect of the Interests as Purchaser desires. 5.2. Defensible Title. (a) "Defensible Title" means such title and ownership of each Seller (pursuant to instruments filed with and, to the extent required, approved by the MMS and filed of record in the appropriate county or parish records or, in the case of those instruments not yet approved by the MMS or not in approvable form and listed in Schedule 3.1(a), pursuant to instruments filed with the MMS and filed of record in the appropriate county or parish records) that, in each case (i) will entitle Purchaser, as the successor to each Seller, to receive and retain now and, except as the result of any action by Purchaser subsequent to the Closing, in the future, without suspension, reduction or termination, not less than the relevant ORI amount of such Seller listed in Schedule 1-A of Substances produced under the terms of the relevant Lease and the proceeds from the sale thereof for the duration of such Lease and (ii) is free of all claims, liens, security interests, encumbrances, irregularities and defects, except for Permitted Encumbrances (as defined below in this Section 5.2). (b) "Permitted Encumbrances" are: (i) mechanics', materialmen's, operator's and non-operators', tax and similar liens or charges arising in the ordinary course of business related to an Interest, if such liens or charges secure payments not yet due; (ii) all consents from, notices to, approvals by or other actions by any governmental authority in connection with the sale or transfer of the Interests of any Seller by such Seller to Purchaser pursuant to this Agreement if such matters are customarily and appropriately obtained after the sale or transfer; -15- (iii) rights of a governmental entity to control or regulate the Interests, together with all applicable laws, rules and regulations; and (iv) easements, rights-of-way, surface leases and other surface use restrictions if such restrictions will not materially adversely affect the use, value or operation of the Interests. 5.3. Waiver of Consumer Rights. To the extent sale of any of the Interests is mandatorily governed by the laws of the State of Texas, Purchaser waives its rights under the Texas Deceptive Trade Practices-Consumer Protection Act, Section 17.41 et seq., Texas Business & Commerce Code, a law that gives consumers special rights and protections. After consultation with an attorney selected by Purchaser, Purchaser voluntarily consents to this waiver. In order to evidence its ability to grant such waiver, Purchaser hereby represents and warrants to each Seller that Purchaser (i) is in the business of seeking or acquiring, by purchase or lease, goods or services for commercial or business use, (ii) has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of the transaction contemplated hereby and (iii) is not in a significantly disparate bargaining position.

(b) Notwithstanding anything provided to the contrary in this Agreement, upon failure of Sellers to fulfill any undertaking or commitment provided for herein on the part of Sellers that is -19- required to be fulfilled on or prior to the Closing Date, Purchaser, at its sole option, shall be entitled to any remedy available at law or in equity.

ARTICLE IX OBLIGATIONS AFTER CLOSING 9.1. Post-Closing Adjustments. Sellers and Purchaser acknowledge that the amount of all adjustments to the Purchase Price under Section 2.2 may not be available prior to the Closing. As soon as practicable after the Closing, but in any event within ninety (90) days after the Closing, Purchaser shall cause HHOC to prepare and submit to each Seller a statement containing adjustments to the Purchase Price contemplated by the provisions of Section 2.2 that were not finally determined as of the Closing (the "Final Settlement Statement") and such supporting documentation as is reasonably necessary to support the adjustments shown therein. Purchaser shall cause HHOC to give representatives of each Seller reasonable access to the premises of HHOC and to the books and records of HHOC for purposes of reviewing the calculation of any such adjustments and will cause appropriate personnel of HHOC to assist each Seller and representatives of any Seller, at no cost to such Seller, in verification of such calculations. The Final Settlement Statement shall become final and binding on Sellers and Purchaser as to the calculation of the Adjusted Purchase Price forty five (45) days following the date the Final Settlement Statement is received by Sellers, except to the extent that, prior to the expiration of such forty five (45) day period, any Seller shall deliver to Purchaser notice, as hereinafter required, of its disagreement with the contents of the Final Settlement Statement. Such notice shall be in writing and set forth all disagreements of any Seller with respect to any portion of the Final Settlement Statement, together with any changes thereto proposed by such Seller, and shall include an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary to support, such changes. If any Seller has timely delivered such a notice of disagreement to Purchaser, then, upon written agreement between Purchaser and Sellers resolving all disagreements set forth in such notice, the Final Settlement Statement shall become final and binding upon Purchaser and Sellers as to the calculation of the Adjusted Purchase Price. If the Final Settlement Statement has not become final and binding by the seventy fifth (75th) day -20- following its receipt by Sellers, then Purchaser or Sellers may submit to a nationally-recognized firm of certified public accountants which neither serves as the auditors for nor provides consulting services to HHOC or any Sellers or Purchaser or such other independent public accounting firm mutually satisfactory to Sellers and Purchaser for resolution any unresolved disagreements of Sellers set forth in the notice from Sellers to Purchaser. The fees and expenses of such accounting firm in making such determination shall be shared equally by Purchaser, on the onehand, and Sellers, on the other. Upon resolution of such unresolved disagreements of Purchaser, the Final Settlement Statement (including any revisions thereto as are so resolved or agreed) shall be conclusive, final and binding upon Purchaser and Sellers as to the calculation of the Adjusted Purchase Price. Payment of any net amount due to Sellers or Purchaser, as the case may be, on the basis thereof shall be made within five (5) days after the Final Settlement Statement (as so resolved or agreed) becomes final and binding on the parties hereto (the "Final Settlement Date"). 9.2. Subsequent Adjustments. Sellers and Purchaser recognize that either Sellers or Purchaser may receive funds or pay expenses after the Final Settlement Date which are properly the property or obligation of the other. Upon receipt of net proceeds or payment of net expenses due to or payable by the other party hereto, whichever occurs first, Sellers or Purchaser, as the case may be, shall submit a statement to the other party hereto showing the relevant items of income and expense. Payment of any net amount due by Sellers or Purchaser, as the case may be, on the basis thereof shall be made within ten (10) days of receipt of the statement. 9.3. Reservation of Claims. Except as provided in this Agreement, each Seller is entitled to all claims related to the Interests of such Seller prior to the Effective Time regardless of when payment is made. Except as provided in this Agreement, Purchaser is entitled to all claims related to the Interests which arise after the Effective Time. 9.4. Files and Records. Upon the Closing, subject to the provisions of Section 1.2(d), Sellers shall permit Purchaser, at the expense of Purchaser, to take possession of originals, or with respect to accounting records relating to periods prior to the Closing Date, copies, of all Records in the possession or control of any Seller or HHOC and relating to the Interests. Each Seller shall have the right to copy (at the expense of such Seller) and retain a copy of all such files, records and data. Insofar as any Seller reasonably believes such Records may be needed or useful in connection with federal, state or local regulatory or tax matters or resolution of existing disputes or contract compliance issues with third parties or for any other appropriate purposes, such Seller shall have the right to make, at the expense of such Seller, and retain copies of Records subsequent to the delivery of such Records to Purchaser; provided, however, any such copies of Records retained by such Seller shall be confidential and proprietary to Purchaser to the extent the relevant Records were theretofore maintained as such by such Seller, and to such extent and except as provided herein to the contrary, such Seller may not divulge any matters contained therein or any other information provided by Purchaser to such Seller pursuant to the terms of this Agreement, without the prior express written consent of Purchaser, except (a) as required by applicable law, (b) as required by order of any court, (c) to the extent otherwise -21- previously made public (other than by disclosure in breach of this Agreement) or (d) as is necessary to enforce, or seek redress for breach of, this Agreement. Except as may be otherwise required by any of the Contracts or applicable law, Purchaser shall be obligated to maintain the Records for a period of seven years following the Closing Date; provided, however, Purchaser shall not be obligated to maintain any Records that relate in all material respects to any of the Interests that cease to be owned by Purchaser if Purchaser has obligated its successors and assigns of such Records to maintain and allow access to such Records for the remainder of such seven-year period; and provided further, however, Purchaser shall not be required to retain any Records that it has offered to deliver to Sellers. 9.5. Further Assurances. After the Closing, Sellers and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary or advisable to carry out their obligations under this Agreement or any other document delivered pursuant hereto. In particular, Sellers and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary and advisable to make all filings, registrations, and recordings which must be made with respect to the ORIs in the records of the MMS and all appropriate counties, parishes, and state agencies and offices in order that the records maintained by the MMS and the appropriate state agencies and the appropriate records of the relevant parishes and counties shall accurately reflect the transfer of the Interests to Purchaser. 9.6. Assumption and Indemnity. (a) Upon the Closing, Purchaser hereby assumes responsibility for and agrees to pay, perform and discharge all duties and obligations of Sellers arising out of or in connection with the ownership of the Interests on or after the Closing Date (collectively, the "Assumed Obligations"). (b) Each Seller, severally and not jointly, shall retain responsibility for and agrees to pay, perform and discharge all costs, expenses, liabilities, claims and obligations arising out of or in connection with the ownership of the Interests of such Seller prior to the Closing Date (the "Retained Obligations"). (c) To the extent Purchaser wishes to make adjustments to any audits with respect to any of the Interests relating to any period prior to the Effective Time, Purchaser shall do so only with the prior written consent of any affected Seller. (d) IN THE EVENT THAT THE CLOSING OCCURS, EXCEPT AS TO MATTERS WAIVED IN WRITING BY THE PARTY HERETO AGAINST WHICH THE WAIVER IS SOUGHT TO BE ENFORCED, (I) PURCHASER SHALL PROTECT, DEFEND, RELEASE, INDEMNIFY AND HOLD HARMLESS EACH SELLER AND THE TRUSTEES, BENEFICIARIES, EMPLOYEES, AND AGENTS OF EACH SELLER AND THE HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS, AND ASSIGNS OF ANY OF THE FOREGOING (EACH A "SELLER INDEMNIFIED PARTY") FROM AND AGAINST ANY AND ALL DAMAGES, CLAIMS, LOSSES, DEMANDS, FINES, PENALTIES, JUDGMENTS (INCLUDING INTEREST), -22- COSTS, EXPENSES, ENVIRONMENTAL LIABILITIES, AND OTHER LIABILITIES, DIRECT, CONTINGENT, OR OTHERWISE, INCLUDING CONSULTANT AND ATTORNEYS' FEES AND COSTS OF COURT ("DAMAGES") WHICH MAY BE ALLEGED AGAINST ANY SELLER INDEMNIFIED PARTY, ARISING OR ACCRUING WITH RESPECT TO (A) ANY REPRESENTATION OR WARRANTY MADE BY PURCHASER IN OR PURSUANT TO THIS AGREEMENT BEING UNTRUE OR INCORRECT IN ANY MATERIAL RESPECT, (B) ANY FAILURE BY PURCHASER TO PERFORM ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT EXECUTED BY IT IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR (C) THE ASSUMED OBLIGATIONS AND (II) EACH SELLER, SEVERALLY AND NOT JOINTLY, SHALL PROTECT, DEFEND, RELEASE, INDEMNIFY AND HOLD HARMLESS PURCHASER AND THE SHAREHOLDERS, DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS OF PURCHASER AND THE HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS, AND ASSIGNS OF ANY OF THE FOREGOING (EACH A "PURCHASER INDEMNIFIED PARTY") FROM ANY DAMAGES WHICH MAY BE ALLEGED AGAINST ANY PURCHASER INDEMNIFIED PARTY, ARISING OR ACCRUING WITH RESPECT TO (A) ANY REPRESENTATION OR WARRANTY MADE BY SUCH SELLER IN OR PURSUANT TO THIS AGREEMENT BEING UNTRUE OR INCORRECT IN ANY MATERIAL RESPECT, (B) ANY FAILURE BY SUCH SELLER TO PERFORM ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT EXECUTED BY IT IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR (C) THE RETAINED OBLIGATIONS OF SUCH SELLER. THE TERM "DAMAGES," AS USED IN THIS SECTION 9.6, SHALL NOT INCLUDE (X) ANY AMOUNT WHICH WAS TAKEN INTO ACCOUNT AS AN ADJUSTMENT TO THE PURCHASE PRICE PURSUANT TO ANY APPLICABLE PROVISION OF THIS AGREEMENT OR (Y) COSTS AND EXPENSES OF EITHER PARTY HERETO AS DESCRIBED IN SECTION 10.2. (e) Neither any Seller Indemnified Party nor any Purchaser Indemnified Party shall be entitled to indemnification under this Section 9.6 unless the aggregate of all amounts for which indemnity would otherwise be due to the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, exceeds $150,000 in the aggregate, in which case the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, shall be entitled to recover in full with respect to all such amounts. This threshold does not apply to (and shall not be satisfied by) defaults related to the payment of money or other liquidated amounts. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL PURCHASER OR ANY SELLER BE LIABLE HEREUNDER FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, STATUTORY, REMOTE OR SPECULATIVE DAMAGES FURTHER NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NEITHER OF SELLERS NOR PURCHASER SHALL BE OBLIGATED TO PROVIDE INDEMNIFICATION TO THE OTHER UNDER THIS SECTION 9.6 EXCEEDING IN THE AGGREGATE AS TO ALL CLAIMS FOR SUCH INDEMNIFICATION, THE AMOUNT SET FORTH BELOW FOR SUCH PARTY: CLAIMS AGAINST OR BY HALL-HOUSTON 1996 EXPLORATION AND DEVELOPMENT FACILITY -23- OVERRIDING ROYALTY TRUST $ 1,923,000 CLAIMS AGAINST OR BY HALL-HOUSTON OIL COMPANY 2000 EXPLORATION AND DEVELOPMENT FACILITY OVERRIDING ROYALTY TRUST $ 2,530,000 9.7. Express Negligence. THE DEFENSE, INDEMNIFICATION AND HOLD HARMLESS PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE DAMAGES IN QUESTION AROSE SOLELY OR IN PART FROM THE ACTIVE, PASSIVE OR CONCURRENT NEGLIGENCE, OR OTHER FAULT (INCLUDING STRICT LIABILITY), OF ANY SELLER INDEMNIFIED PARTY OR PURCHASER INDEMNIFIED PARTY. PURCHASER AND EACH SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS. 9.8. Indemnification Procedure. All claims for indemnification under the provisions of Section 9.6 shall be asserted and resolved pursuant to the provisions of this Section 9.8. Any person or entity claiming indemnification hereunder is hereinafter referred to as the "Indemnified Party" and any person or entity against whom such claims are asserted hereunder is hereinafter referred to as the "Indemnifying Party." In the event that any Damages are asserted against or sought to be collected from an Indemnified Party by a third party, such Indemnified Party shall, with reasonable promptness, provide to the Indemnifying Party a written notice of claim specifying, in reasonable detail, the specific nature of and specific basis of the Damages and the estimated amount of such Damages and including a copy of all papers served with respect to such claim (if any) and the basis of such claim for indemnification under the provisions of Section 9.6 (each a "Claim Notice"). Notwithstanding the preceding sentence, failure of an Indemnified Party to give notice hereunder shall not release the Indemnifying Party from its obligations under the provisions of Section 9.6, except to the extent the Indemnifying Party is actually prejudiced by such failure to give notice; provided that, the Indemnifying Party shall not be obligated to defend, indemnify or otherwise hold harmless an Indemnified Party with respect to a third party claim until a Claim Notice meeting the foregoing requirements is furnished to the Indemnifying Party by the party seeking indemnity hereunder. The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of any Claim Notice (the "Notice Period") in which to notify the Indemnified Party whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Damages. If the Indemnifying Party fails to so notify the Indemnified Party during the Notice Period, the Indemnifying Party shall be deemed to have elected to dispute such liability. The Indemnified Party shall have the duty to defend such third party claim by all appropriate proceedings, and with counsel of its own choosing, which proceedings shall be promptly settled or prosecuted to a final conclusion. If the Indemnifying Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense.

The fees and expenses of such accounting firm in making such determination shall be shared equally by Purchaser and Seller. Upon resolution of such unresolved disagreements of Seller, the Final Settlement Statement (including any revisions thereto as are so resolved or agreed) shall be conclusive, final and binding upon Purchaser and Seller as to the calculation of the Adjusted Purchase Price. Payment of any net amount due to Seller or Purchaser, as the case may be, on the basis thereof shall be made within five (5) days after the Final Settlement Statement (as so resolved or agreed) becomes final and binding on the parties hereto (the "Final Settlement Date"). 9.2 Subsequent Adjustments. Seller and Purchaser recognize that either Seller or Purchaser may receive funds or pay expenses after the Final Settlement Date which are properly the property or obligation of the other. Upon receipt of net proceeds or payment of net expenses due to or payable by the other party hereto, whichever occurs first, Seller or Purchaser, as the case may be, shall submit a statement to the other party hereto showing the relevant items of income and expense. Payment of any net amount due by Seller or Purchaser, as the case may be, on the basis thereof shall be made within ten (10) days of receipt of the statement. 9.3 Reservation of Claims. Except as provided in this Agreement, Seller is entitled to all claims related to the Interests prior to the Effective Time regardless of when payment is made. Except as provided in this Agreement, Purchaser is entitled to all claims related to the Interests which arise after the Effective Time. 9.4 Files and Records. Upon the Closing, subject to the provisions of Section 1.2(d), Seller shall permit Purchaser, at the expense of Purchaser, to take possession of originals, or with respect to accounting records relating to periods prior to the Closing Date, copies, of all Records in the possession or control of Seller or HHOC and relating to the Interests. Seller shall have the right to copy (at the expense of Seller) and retain a copy of all such files, records and data. Insofar as Seller reasonably believes such Records may be needed or useful in connection with federal, state or local regulatory or tax matters or resolution of existing disputes or contract compliance issues with third parties or for any other appropriate purposes, Seller shall have the right to make, at the expense 16 of Seller, and retain copies of Records subsequent to the delivery of such Records to Purchaser; provided, however, any such copies of Records retained by Seller shall be confidential and proprietary to Purchaser to the extent the relevant Records were theretofore maintained as such by Seller, and to such extent and except as provided herein to the contrary, Seller may not divulge any matters contained therein or any other information provided by Purchaser to Seller pursuant to the terms of this Agreement, without the prior express written consent of Purchaser, except (a) as required by applicable law, (b) as required by order of any court, (c) to the extent otherwise previously made public (other than by disclosure in breach of this Agreement) or (d) as is necessary to enforce, or seek redress for breach of, this Agreement. Except as may be otherwise required by any of the Contracts or applicable law, Purchaser shall be obligated to maintain the Records for a period of seven years following the Closing Date; provided, however, Purchaser shall not be obligated to maintain any Records that relate in all material respects to any of the Interests that cease to be owned by Purchaser if Purchaser has obligated its successors and assigns of such Records to maintain and allow access to such Records for the remainder of such seven-year period; and provided further, however, Purchaser shall not be required to retain any Records that it has offered to deliver to Seller. 9.5 Further Assurances. After the Closing, Seller and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary or advisable to carry out their obligations under this Agreement or any other document delivered pursuant hereto. In particular, Seller and Purchaser agree to execute and deliver such instruments and take such other actions as may be necessary and advisable to make all filings, registrations, and recordings which must be made with respect to the ORIs in the records of the MMS and all appropriate counties, parishes, and state agencies and offices in order that the records maintained by the MMS and the appropriate state agencies and the appropriate records of the relevant parishes and counties shall accurately reflect the transfer of the Interests to Purchaser. 9.6 Assumption and Indemnity. (a) Upon the Closing, Purchaser hereby assumes responsibility for and agrees to pay, perform and discharge all duties and obligations of Seller arising out of or in connection with the ownership of the Interests on or after the Closing Date (collectively, the "Assumed Obligations"). (b) Seller, severally and not jointly, shall retain responsibility for and agrees to pay, perform and discharge all costs, expenses, liabilities, claims and obligations arising out of or in connection with the ownership of the Interests prior to the Closing Date (the "Retained Obligations"). (c) To the extent Purchaser wishes to make adjustments to any audits with respect to any of the Interests relating to any period prior to the Effective Time, Purchaser shall do so only with the prior written consent of Seller. (d) IN THE EVENT THAT THE CLOSING OCCURS, EXCEPT AS TO MATTERS WAIVED IN WRITING BY THE PARTY HERETO AGAINST WHICH THE WAIVER IS SOUGHT TO BE ENFORCED, (I) 17 PURCHASER SHALL PROTECT, DEFEND, RELEASE, INDEMNIFY AND HOLD HARMLESS SELLER AND THE TRUSTEES, BENEFICIARIES, EMPLOYEES, AND AGENTS OF SELLER AND THE HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS, AND ASSIGNS OF ANY OF THE FOREGOING (EACH A "SELLER INDEMNIFIED PARTY") FROM AND AGAINST ANY AND ALL DAMAGES, CLAIMS, LOSSES, DEMANDS, FINES, PENALTIES, JUDGMENTS (INCLUDING INTEREST), COSTS, EXPENSES, ENVIRONMENTAL LIABILITIES, AND OTHER LIABILITIES, DIRECT, CONTINGENT, OR OTHERWISE, INCLUDING CONSULTANT AND ATTORNEYS' FEES AND COSTS OF COURT ("DAMAGES") WHICH MAY BE ALLEGED AGAINST ANY SELLER INDEMNIFIED PARTY, ARISING OR ACCRUING WITH RESPECT TO (A) ANY REPRESENTATION OR WARRANTY MADE BY PURCHASER IN OR PURSUANT TO THIS AGREEMENT BEING UNTRUE OR INCORRECT IN ANY MATERIAL RESPECT, (B) ANY FAILURE BY PURCHASER TO PERFORM ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT EXECUTED BY IT IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR (C) THE ASSUMED OBLIGATIONS AND (II) SELLER SHALL PROTECT, DEFEND, RELEASE, INDEMNIFY AND HOLD HARMLESS PURCHASER AND THE SHAREHOLDERS, DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS OF PURCHASER AND THE HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS, AND ASSIGNS OF ANY OF THE FOREGOING (EACH A "PURCHASER INDEMNIFIED PARTY") FROM ANY DAMAGES WHICH MAY BE ALLEGED AGAINST ANY PURCHASER INDEMNIFIED PARTY, ARISING OR ACCRUING WITH RESPECT TO (A) ANY REPRESENTATION OR WARRANTY MADE BY SELLER IN OR PURSUANT TO THIS AGREEMENT BEING UNTRUE OR INCORRECT IN ANY MATERIAL RESPECT, (B) ANY FAILURE BY SELLER TO PERFORM ANY COVENANT OR AGREEMENT SET FORTH IN THIS AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT EXECUTED BY IT IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR (C) THE RETAINED OBLIGATIONS. THE TERM "DAMAGES," AS USED IN THIS SECTION 9.6, SHALL NOT INCLUDE (X) ANY AMOUNT WHICH WAS TAKEN INTO ACCOUNT AS AN ADJUSTMENT TO THE PURCHASE PRICE PURSUANT TO ANY APPLICABLE PROVISION OF THIS AGREEMENT OR (Y) COSTS AND EXPENSES OF EITHER PARTY HERETO AS DESCRIBED IN SECTION 10.2. (e) Neither any Seller Indemnified Party nor any Purchaser Indemnified Party shall be entitled to indemnification under this Section 9.6 unless the aggregate of all amounts for which indemnity would otherwise be due to the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, exceeds $50,000 in the aggregate, in which case the Seller Indemnified Parties or the Purchaser Indemnified Parties, as the case may be, shall be entitled to recover in full with respect to all such amounts. This threshold does not apply to (and shall not be satisfied by) defaults related to the payment of money or other liquidated amounts. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL PURCHASER OR SELLER BE LIABLE HEREUNDER FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL, STATUTORY, REMOTE OR SPECULATIVE DAMAGES FURTHER NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NEITHER SELLERS NOR PURCHASER SHALL BE OBLIGATED TO PROVIDE INDEMNIFICATION UNDER THIS SECTION 9.6 EXCEEDING IN THE AGGREGATE AS TO ALL CLAIMS FOR SUCH INDEMNIFICATION, $1,000,000. 9.7 Express Negligence. THE DEFENSE, INDEMNIFICATION AND HOLD HARMLESS PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE 18 DAMAGES IN QUESTION AROSE SOLELY OR IN PART FROM THE ACTIVE, PASSIVE OR CONCURRENT NEGLIGENCE, OR OTHER FAULT (INCLUDING STRICT LIABILITY), OF ANY SELLER INDEMNIFIED PARTY OR PURCHASER INDEMNIFIED PARTY. PURCHASER AND SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS. 9.8 Indemnification Procedure. All claims for indemnification under the provisions of Section 9.6 shall be asserted and resolved pursuant to the provisions of this Section 9.8. Any person or entity claiming indemnification hereunder is hereinafter referred to as the "Indemnified Party" and any person or entity against whom such claims are asserted hereunder is hereinafter referred to as the "Indemnifying Party." In the event that any Damages are asserted against or sought to be collected from an Indemnified Party by a third party, such Indemnified Party shall, with reasonable promptness, provide to the Indemnifying Party a written notice of claim specifying, in reasonable detail, the specific nature of and specific basis of the Damages and the estimated amount of such Damages and including a copy of all papers served with respect to such claim (if any) and the basis of such claim for indemnification under the provisions of Section 9.6 (each a "Claim Notice"). Notwithstanding the preceding sentence, failure of an Indemnified Party to give notice hereunder shall not release the Indemnifying Party from its obligations under the provisions of Section 9.6, except to the extent the Indemnifying Party is actually prejudiced by such failure to give notice; provided that, the Indemnifying Party shall not be obligated to defend, indemnify or otherwise hold harmless an Indemnified Party with respect to a third party claim until a Claim Notice meeting the foregoing requirements is furnished to the Indemnifying Party by the party seeking indemnity hereunder. The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of any Claim Notice (the "Notice Period") in which to notify the Indemnified Party whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Damages. If the Indemnifying Party fails to so notify the Indemnified Party during the Notice Period, the Indemnifying Party shall be deemed to have elected to dispute such liability. The Indemnified Party shall have the duty to defend such third party claim by all appropriate proceedings, and with counsel of its own choosing, which proceedings shall be promptly settled or prosecuted to a final conclusion. If the Indemnifying Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. If requested by the Indemnified Party, the Indemnifying Party agrees to cooperate with the Indemnified Party and its counsel in contesting any Damages that the Indemnified Party elects to contest. No claim may be settled or otherwise compromised without the prior written consent of the Indemnifying Party. If the Indemnifying Party disputes whether a third party claim is an indemnified claim under the provisions of Section 9.6, the determination of whether the Indemnified Party is entitled to indemnification under the provisions of Section 9.6 shall be resolved pursuant to arbitration as provided in Section 10.16. 9.9 Allocation of Proceeds. Seller shall receive all proceeds from the sale of Substances physically produced or allocable to the Interests prior to the Effective Time. Purchaser shall receive all proceeds from the sale of Substances physically produced or allocable to the Interests on or after the Effective Time. 19 9.10 Termination of Confidentiality Agreements. Effective upon the Closing, the obligations of Purchaser under the Confidentiality Agreements, insofar and only insofar as they relate to the Interests, are terminated. ARTICLE X MISCELLANEOUS 10.1 Notices.

THIS AGREEMENT AND THE DOCUMENTATION TO BE EXECUTED AND DELIVERED AT THE CLOSING CONSTITUTE THE ENTIRE UNDERSTANDING BETWEEN SELLER AND PURCHASER CONCERNING THE SUBJECT MATTER OF THIS AGREEMENT AND SUPERSEDE ALL NEGOTIATIONS, DISCUSSIONS, REPRESENTATIONS, PRIOR AGREEMENTS AND UNDERSTANDINGS, WHETHER ORAL OR WRITTEN, EXCEPT THE CONFIDENTIALITY AGREEMENT. 10.13 Parties in Interest. Except as otherwise expressly provided herein, this Agreement is binding upon and shall inure to the benefit of Seller and Purchaser and their respective successors, representatives, and permitted assigns.

The covenants, agreements, representations, warranties and indemnities contained in this Agreement shall survive the Closing of the transactions contemplated hereby; provided, however, except as to the representations and warranties made by each Seller in Sections 3.1(a), (b), (c), (d) and (e), the representations and warranties made by each Seller in this Agreement and indemnities by each Seller associated therewith shall survive the Closing for eighteen months only. 22 10.16 Arbitration. Except as provided in Section 9.1 and below in this Section 10.16, any dispute, controversy or claim arising out of or in relation to or in connection with this Agreement, including any dispute as to the construction, validity, interpretation, enforceability or breach of this Agreement, shall be exclusively and finally settled by arbitration in accordance with this Section 10.16.

The arbitration shall be heard and determined by three arbitrators. Each side shall appoint an arbitrator of its choice within twenty (20) days of the submission of the notice of arbitration. The party-appointed arbitrators shall in turn appoint a presiding arbitrator for the tribunal within twenty (20) days following the appointment of the second party-appointed arbitrator. If the party-appointed arbitrators cannot reach agreement on a presiding arbitrator for the tribunal and/or one party fails to appoint its party-appointed arbitrator within the applicable period, the AAA shall act as appointing authority to appoint an independent arbitrator with at least ten (10) years experience in the legal and/or commercial aspects of the petroleum exploration and production industry. None of the arbitrators shall have been an employee or consultant to either party to the arbitration or any of their respective Affiliates, or have any financial interest in the dispute, controversy or claim. All decisions of the arbitral tribunal shall be by majority vote. The arbitrators may not award consequential, punitive or similar damages except those claimed by persons other than Seller and Purchaser for which responsibility is being allocated between the parties. Expenses in connection with the arbitration and the compensation and expenses of the arbitrators shall be borne in such manner as may be specified in the arbitral award. Privileges protecting attorney-client communications and attorney work product from compelled disclosure or use in evidence, as recognized by the Federal Rules of Civil Procedure, shall apply to and be binding in any arbitration proceeding conducted under this Section 10.16. This Section 10.16 does not apply to any dispute, controversy or claim in which the claimant seeks injunctive, declaratory or other equitable relief, and each party hereto reserves its right to bring such action in court, which the parties hereto agree shall be exclusively the U.S. Federal Courts sitting in the Eastern District of Louisiana and each party hereto irrevocably consents to personal jurisdiction in any and all such tribunals.

Notwithstanding the foregoing, no Indemnifying Shareholder shall have any liability under this Section 5(a) unless the Damages otherwise compensable under this Section 5(a) exceed $1,000,000. Notwithstanding the foregoing, except as provided in the succeeding sentence, in no event shall any Indemnifying Shareholder's aggregate liability under this Section 5 exceed the value of the Merger Consideration exclusive of any Earnout received by such Indemnifying Shareholder; provided, that solely for purposes of this Section 5, each Warrant received by an Indemnifying Shareholder shall be valued at $.75.

Any additional consideration that certain In- -7- demnifying Shareholders may receive in respect of New Company Preferred Stock as contemplated by Section 5.10 of the Merger Agreement shall be excluded from the calculations of aggregate liability under this Section 5. (b) Survival. Each of the representations and warranties contained in Article III of the Merger Agreement will survive the Closing and remain in full force and effect until (a) in the case of all representations and warranties contained in Sections 3.1, 3.2, 3.3, 3.5, 3.8, 3.15 and 3.20 of the Merger Agreement and Sections 6(a)-(c) of this Agreement, three years following the Effective Date, and (b) in the case of all other representations and warranties, eighteen months following the Effective Date, at which respective times such representations and warranties shall expire. The covenants and agreements contained herein shall survive the Closing and remain in effect in accordance with their terms. (c) Defense of Claims. (i) Promptly, but in any event not later than twenty calendar days after receipt by any member of the Buyer Group (in any such case, the "Beneficiary"), of notice of any claim or potential claim or the commencement of any Action by any Person that is not a party to this Agreement or a member of the Buyer Group (a "Third Party Claim"), which could give rise to a right to indemnification pursuant to Section 5(a), the Beneficiary shall give the party who may become obligated to provide indemnification hereunder (the "Indemnitor") written notice describing the Third Party Claim in reasonable detail. (ii) Any claim by a Beneficiary on account of Damages that does not result from a Third Party Claim (a "Direct Claim") shall be asserted by giving the Indemnitor reasonably prompt written notice thereof, but in any event not later than 45 calendar days after the Beneficiary becomes aware of such Direct Claim. The remedies available to the Beneficiary for any Direct Claim shall remain subject to the applicable terms and provisions of this Section 5 (including, without limitation, Section 5(b) hereof). (iii) A failure to give timely notice or to include any specified information in any notice as provided in Section 5(c)(i) or (ii) hereof will not affect the rights or obligations of any party hereunder except and only to the extent that, as a result of such failure, any party which was entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise damaged as a result of such failure. (d) Subrogation. Upon making any payment pursuant to Section 5(a), the Indemnitor shall, to the extent of such payment, be subrogated to all rights of the Beneficiary against any third party that is not an Affiliate of the Beneficiary in respect of the Damages to which the payment relates; provided, however, that (i) the Indemnitor shall then be in material compliance with its obligations under this Agreement in respect of such Damages and (ii) until the Beneficiary recovers full payment of its Damages, any and all claims of the Indemnitor against any such third party on account of such payment will be subordinated in right of payment to the Beneficiary's rights against such third party, and the Indemnitor shall postpone any of its remedies against any such third party with respect to such payment. Without limiting the generality or effect of any other provision hereof, each such -8- Beneficiary and Indemnitor shall duly execute upon request all instruments reasonably necessary to evidence and perfect the above-described subrogation and subordination rights. 6. Representations and Warranties of Principal Shareholders. Each Principal Shareholder hereby severally and not jointly (and solely with respect to itself and the Subject Instruments by such Principal Shareholder) represents and warrants to Buyer as follows: (a) Ownership of Subject Instruments.

Upon the request of any Holder of Registrable Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. SECTION 2.5. Indemnification. (a) In the event of registration of Registrable Securities under the Securities Act pursuant to this Agreement, the Company will, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, the seller of such Registrable Securities covered by the Shelf Registration Statement, its directors and officers or general and -6- limited partners (and the directors and officers thereof) (each, a "Person"), and each other Person, if any, who controls such seller within the meaning of the Securities Act, against any and all losses, claims, damages or liabilities, joint or several, and expenses (including fees of counsel and any amounts paid in any settlement approved by the Company (which such approval shall not be unreasonably withheld or delayed)) to which such seller may become subject under the Securities Act, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof), or expenses arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement under which such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (together with the documents incorporated by reference or filed with the Commission) and any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Company shall not be liable to any such seller in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding, whether commenced or threatened, in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or amendment thereof or supplement thereto or in any such Prospectus in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of any such seller expressly for use in the preparation thereof. (b) The Company, as a condition to including Registrable Securities in the Shelf Registration Statement filed in accordance with this Agreement, shall have received an undertaking reasonably satisfactory to it from the prospective seller of such Registrable Securities to indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) of this Section 2.5) the Company and its directors and officers and all other prospective sellers and their directors, officers, general and limited partners and respective controlling Persons (within the meaning of the Securities Act) with respect to any statement or alleged statement in or omission or alleged omission from the Shelf Registration Statement, any Prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or information has been furnished in writing to the Company or its representative by or on behalf of such seller expressly for use in the preparation of the Shelf Registration Statement or such Prospectus, amendment or supplement; provided, however, that the aggregate amount which any such seller or prospective seller shall be required to pay pursuant to such undertaking shall be limited to the amount of the net proceeds received by such Person upon the sale of the Registrable Securities pursuant to the Shelf Registration Statement giving rise to such claim. Such indemnity shall remain in full force and effect following the transfer of such securities by such seller. (c) As soon as possible after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 2.5 such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as pro- -7- vided herein shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 2.5, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to such indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 2.5 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof unless the indemnifying party has failed to assume the defense of such claim or to employ counsel reasonably satisfactory to such indemnified party. No indemnifying party will consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimants or plaintiffs to such indemnified party of an unconditional release from all liability in respect to such claim or litigation. No indemnifying party will be liable for any settlement effected without its prior written consent, which consent will not be unreasonably withheld or delayed. (d) If the indemnification provided for in this Section 2.5 is unavailable or insufficient to hold harmless an indemnified party under Section 2.5(a) or (b), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in Section 2.5(a) or (b) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand in connection with statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue or alleged untrue statements or omissions. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 2.5(d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this Section 2.5(d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 2.5(c) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim (which shall be limited as provided in Section 2.5(d) if the indemnifying party has assumed the defense of any such action in accordance with the provisions thereof) which is the subject of this Section 2.5(d). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Promptly after receipt by an indemnified party under this Section 2.5(d) of notice of the commencement of any action against such party in respect of which a claim for contribution may be made against an indemnifying party under this Section 2.5(d), such indemnified party shall notify the indemnifying party in writing of the commencement thereof if the notice specified in Section 2.5(c) has not been given with respect to such action; provided that the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise under this Section 2.5(d), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. Notwithstanding -8- anything in this Section 2.5(d) to the contrary, no indemnifying party (other than the Company) shall be required pursuant to this Section 2.5(d) to contribute any amount in excess of the proceeds received by such indemnifying party from the sale of Registrable Securities in the offering to which the losses, claims, damages or liabilities of the indemnified parties relate.
