ARTICLE 3 SERVICES AGREEMENT 3.1	MOXY Obligation to Use HES Services; Exceptions (a) 	Where MOXY acts as operator of an oil and gas property, MOXY will use HES Services exclusively during the Term hereof, provided that MOXY shall not be required to utilize HES Services with respect to any service or product which (i) 	HES does not generally provide in the Gulf of Mexico and the Gulf Coast area; (ii) 	HES is unwilling or unable to deliver within a time frame which is reasonably acceptable to MOXY; (iii) 	is not in the best interest of economic and efficient recovery of hydrocarbons, it being understood that the determination of the existence of this condition shall not be based primarily on pricing considerations; (iv) 	in MOXY's opinion, unless substantiated otherwise by HES in written materials, will or has the potential to result in substandard performance or higher costs which could adversely impact either productivity or financial performance; (v) 	has been proven to result consistently in substandard well productivity and performance, or substandard wellbore evaluation; (vi) 	is experimental or untested; or (vii)	applies to specific tasks to the extent of: (a) any existing agreements that bind MOXY to use other products or services or limit or prohibit the use of HES Services as provided herein (being those agreements listed on Exhibit "A"), and (b) any new agreements entered into by MOXY on new prospects, that limit or prohibit MOXY from utilizing HES Services; provided, however, MOXY will use commercially reasonable efforts to obtain waivers of such limitations and prohibitions wherever practicable, and MOXY will not enter into new alliances with service providers that conflict with the commitment made by MOXY under this Article 3 to utilize HES Services. HES certifies that based on its knowledge of the market, the Market Rates provided for herein are fully competitive. MOXY believes that these Market Rates will satisfy its obligation under the Texaco Joint Operating Agreement and other agreements to use competitive rates (or similar general term) for products and services. MOXY further agrees to use good faith efforts to uphold such rates as competitive in any third party audits or claims where the competitive nature of such pricing is an issue. The agreement of MOXY as expressed above is not applicable to major construction or other similar projects that are subject to requirements calling for the use of formal bidding procedures. 	(b)	Notwithstanding the provisions of Section 3.1(a) above, where MOXY acts as operator of an oil and gas property and plans to conduct a drilling or other operation pursuant to a turnkey-type contract, MOXY shall specify the use of HES Services under such turnkey-type contract unless the use of such HES Services will have a material adverse impact on the overall attractiveness of such turnkey-type contract, it being understood that overall value as well as pricing shall be taken into consideration. 3.2	Market Rates; Prevailing Terms and Conditions 	HES and its Affiliates shall invoice MOXY for HES Services on the basis of Market Rates, as follows: (a)	For all oilfield services (including but not limited to all wellbore services) that Halliburton Energy Services (or other HES Affiliates) routinely provides and that satisfy the requirements of Section 3.1, the term "Market Rates" means Halliburton Energy Services' Established Book Prices for the general area where the work is being performed (e.g., the Gulf of Mexico, onshore Louisiana/Texas Gulf Coast, etc.), less *********. The oilfield services covered by this subparagraph (a) are listed in Part I of Exhibit "A" to the HES/MOXY Master Service Contract. The ******* discount percentage for these oilfield services using the above described Market Rates definition, for the period from the effective date hereof through June 30, 2000, shall be as set forth on Part I of Exhibit "A" to the HES/MOXY Master Service Contract. HES shall provide MOXY, within thirty (30) days following the end of each calendar quarter, with an update on the ******** discount for all such oilfield services, in accordance with the above described Market Rates definition, together with a written certification as to the correctness of such discounts by a vice-president of Halliburton Energy Services. Such discounts shall be effective as of the first day of the second calendar month of the quarter in which the update is provided. Part I of Exhibit "A" to the HES/MOXY Master Service Contract shall be revised periodically to reflect changes in the listed Services and other modifications, as appropriate. 	(b)	For all other Services that HES or its Affiliates provide and that satisfy the requirements of Section 3.1, the term "Market Rates" means the current competitive market rate *******, mutually agreed upon by HES, or its designee, and MOXY, for the applicable Service. A listing of these Services as contemplated at the time of execution of this Agreement, as well as the Market Rates for these Services, for the period from the effective date hereof through June 30, 2000, shall be as set forth in Part II of Exhibit "A" to the HES/MOXY Master Service Contract. These Market Rates will be renegotiated on a semi-annual basis (unless otherwise mutually agreed) using the Market Rates standard described in this subparagraph (b). With respect to any Services not listed in Part II of Exhibit "A" to the HES/MOXY Master Service Contract, the Parties will negotiate a competitive Market Rate for such Service at the time MOXY proposes the use of the unlisted product or service. The rates recited in Part II of Exhibit "A" to the HES/MOXY Master Service Contract shall be revised whenever necessary to reflect all changes as provided for herein. 	With respect to the negotiation of Market Rates described in subparagraph (b) of this Section 3.2, HES and its Affiliates will act in good faith with respect to the use of their knowledge of competitive market rates that will exist from time to time during the Term, it being intended that the Market Rates determined under Section 3.2(b) will generally be at least as favorable to MOXY as the Market Rates determined under Section 3.2(a) for oilfield services. Notwithstanding the provisions of this Article 3, should the Parties fail to agree, after good faith negotiations, on a negotiated or renegotiated Market Rate under this Section 3.2(b) for particular Services of HES or any of its Affiliates (including Brown & Root Energy Services), then MOXY shall not be obligated to use such Services for the applicable semi-annual period(s). (c)	Except as otherwise provided herein, the terms and conditions governing the performance of services by HES pursuant to this Article 3 are set forth in the HES/MOXY Master Service Contract. In the event services are required of Affiliates of HES, the terms and conditions of the HES/MOXY Master Service Contract shall be applicable to such services pending the execution of a separate master services agreement with such Affiliates, it being understood, however, that such Affiliate master services agreement shall contain substantially the same terms and conditions as the HES/MOXY Master Service Contract including application of Market Rates. Notwithstanding the above, if the services to be provided are of the type that customarily are covered by an agreement designed to address the particular (and usually more complex) requirements for that type of service, such as fabrication and installation services, unusually hazardous services and turnkey services, where a master services agreement is not customarily utilized, then the parties will utilize a mutually acceptable form of agreement specifically addressing the particular requirements for that service. 3.3	MOXY Audit Rights MOXY will have the right, not more frequently than once per calendar quarter, to engage an independent auditing firm (i) to audit the rates and conditions that HES is charging for HES Services; and (ii) to verify whether these rates and conditions are consistent with the terms of this Agreement, including but not limited to the requirements of Section 3.2; provided, however, such audit and verification of the Market Rates established by negotiation pursuant to Section 3.2(b) hereof shall not include any examination or audit of *********. The Parties agree that MOXY has the right to utilize the same independent auditing firm that MOXY uses to audit its own records to conduct the above-described audit. HES may require the firm conducting such audit to agree to treat as confidential and not disclose to MOXY *********. Upon completion of any such audit, the independent auditor shall issue its report to MOXY and HES. In the event the independent auditor determines that HES is not invoicing MOXY at rates or offering conditions consistent with the terms hereof, the independent auditor shall, following consultations with MOXY, advise the Parties of the value of the price discrepancy and the details of the inconsistency. In such event, HES shall have fifteen (15) days following receipt of such advice from the auditors to either: (i) correct the discrepancy through a payment to MOXY and, as appropriate, provide amendments to the applicable service or supply agreements containing an appropriate adjustment of contractual conditions, or (ii) notify MOXY in writing that it contests the findings of the auditor including a detailed list of the items contested and an appropriate explanation of the reasons for its disagreement. In the case of a contest under (ii) above, the Parties will use diligent efforts to promptly and fully resolve the contested items. The same procedures for corrections or notifications that are described above shall apply to MOXY in the event the independent auditor determines that a discrepancy exists in favor of HES. ARTICLE 4 INTEGRATION OF HES TECHNICAL PERSONNEL 4.1	Integration of HES Personnel MOXY and HES will develop an organizational structure involving MOXY and HES employees to manage the tasks associated with exploration, development and producing operations on Prospects and Eligible Properties. MOXY and HES will work together in an integrated team approach on a mutually agreed basis, provided that MOXY shall maintain overall authority concerning all operations and activities relating to such Eligible Properties and Prospects. The provisions of this Article 4 shall apply solely to the utilization of the HES personnel described in this Article 4 and not to the personnel of HES and its Affiliates as described in Article 3 and the HES/MOXY Master Service Contract. 4.2	MOXY to Provide Office Space, Equipment; Conditions Binding HES Personnel HES will provide its technical personnel to MOXY on a full time or part time basis as needed by MOXY and mutually agreed by MOXY and HES. MOXY will provide HES's personnel with office space in MOXY's New Orleans office or in an office where work on Prospects, potential Prospects, or acreage associated therewith is being conducted. In addition, MOXY will provide the necessary office and other facilities, comparable to those provided to MOXY employees and other MOXY consultants, conducting similar types of work, in MOXY's New Orleans offices, in order to allow HES's personnel to work with, consult or advise on matters directly related to the Prospects and potential Prospects. The above described MOXY office space and facilities shall be provided at MOXY's expense. At MOXY's request, HES will remove and replace its personnel and will not remove or reassign key personnel assigned to the work contemplated hereunder without MOXY's approval, which will not be unreasonably withheld. Any HES personnel located in a MOXY designated office will be subject to the rules, guidelines, policies and procedures applicable to MOXY employees resident in MOXY's office. In addition, HES shall require all such HES personnel to comply with the confidentiality provisions of this Agreement (Section 8.1) and with the confidentiality provisions of all farmouts, subleases and other agreements to which MOXY is bound, and HES shall serve as guarantor of such personnel's compliance with these confidentiality obligations. With respect to the provision of services by HES personnel under this Article 4, the insurance and indemnity provisions of the mutually agreed Master Service Contract described in Section 3.2 shall be applicable. 4.3	HES/MOXY Master Consulting Agreement 	The terms and conditions of the HES/MOXY Master Consulting Agreement, including but not limited to the compensation provisions thereof, shall govern the performance of such services. ARTICLE 5 PARTICIPATION PROVISIONS 5.1	Eligible Properties The oil and gas properties that are subject to this Agreement and which may qualify as Prospects hereunder, shall include any exploration properties or prospects in which MOXY holds, acquires, or obtains a right to acquire a working interest during the term of this Agreement (other than as provided in the final sentence of Section 1.2(x) (the "Eligible Properties"). 5.2	Identification and Development of Prospects During the Term hereof, MOXY will continue to evaluate Eligible Properties for their commercial potential as Prospects. In this connection, MOXY will, as it deems appropriate, develop and assess geological and geophysical data, conduct exploration activities, acquire oil and gas interests (or the right to do so), and drill Initial Test Wells. 5.3	Designation of Prospect, Election Point Notification Subject to the provisions of Section 6.5 hereof, MOXY shall issue an Election Point Notification to HES whenever during the Term hereof MOXY proposes to develop a Prospect for the production of oil and/or gas. MOXY's obligation to issue an Election Point Notification to HES shall also extend to any Prospect where an Initial Test Well encounters commercial hydrocarbons prior to the end of the Term and MOXY proposes to commence development of the Prospect within six months following the expiration of the Term. The Election Point Notification shall include: (a)	Description of the Prospect. A description of the Prospect (in accordance with Section 1.2(x)), together with a summary of the geological and geophysical data, well logs, production tests (if applicable) and other information which MOXY deems relevant. (b)	Development Plan. A Development Plan that describes the required scope of the development activities and operations that MOXY anticipates to produce the Prospect hydrocarbons. The Development Plan may be amended or supplemented, at any time, by mutual agreement of the Parties. The Parties further acknowledge that the failure to agree on any amendment or supplement of the Development Plan that represents a material alteration thereof will not prevent MOXY from proposing or conducting further operations respecting a Prospect, pursuant to the applicable Operating Agreement, and HES's participation with respect thereto shall be governed by Section 5.6(b). If the Development Plan includes one or more exploration wells (and facilities related thereto), then MOXY shall segregate and reasonably allocate for each such exploration well on an incremental cost basis (including costs such as the cost of additional platform slots or larger facilities), the costs thereof included within such Development Plan. (c)	Estimate of Initial Participation Payment. A statement containing an estimate of the total amount of the costs and expenses that will constitute the Initial Participation Payment. (d)	Statement of Interests that MOXY Program Participants Hold in the Prospect. A Statement of Interests that (i) advises HES of the interests that MOXY Program Participants hold in the Prospect; and (ii) describes the HES Share, as it would apply to exploration costs, development costs, and revenues, both before Prospect Pay-Out and after Prospect Pay-Out. Exhibit "C" contains a form of Election Point Notification. Prior to issuing the Election Point Notification with accompanying materials to HES on a Prospect, MOXY will make available to HES in MOXY's offices or other mutually agreed location(s) all data and information in MOXY's possession and control relating to the Prospect in order to assist HES in making an informed decision regarding participation in such Prospect. Notwithstanding the foregoing, HES acknowledges that MOXY has no obligation to make available data or information that does not exist, is unavailable or as to which MOXY is prohibited from disclosing to HES, and that MOXY makes no representations or warranties relating to any geologic maps or other materials reflecting interpretations by the personnel of MOXY, its consultants or others. HES also acknowledges that MOXY shall not be obligated to generate or produce data, information or materials that it is not producing for its own purposes in connection with making its own decision regarding development of the Prospect. The types of materials that the Parties anticipate being made available, depending on the particular Prospect involved, are shown on Part II of Exhibit "C". 5.4	Exercise of Option, Issuance of Acceptance HES shall have ten (10) days from receipt of an Election Point Notification (or thirty (30) days if the total cost to HES for participation in the Development Plan (including the Initial Participation Payment) is more than $20,000,000) to advise MOXY, in writing: (a) 	that it will participate in the Prospect (the "Acceptance"), in which event it will have the rights and obligations set forth below in this Agreement as to the Prospect, including but not limited to, those described in Sections 5.5 through 5.7; or (b) 	that it will not participate in the Prospect, in which event HES will have no rights or obligations as to such Prospect except that the provisions of Article 5.8 will be applicable. Failure of HES to make an election within the time period identified above shall constitute an election not to participate. Notwithstanding anything to the contrary contained in this Agreement, in the event the Development Plan for a Prospect includes one or more exploration wells (and facilities related thereto), HES may, at the same time that it makes its primary election for the Prospect, elect to not participate in the costs associated with one or more of such exploration well(s) (including the facility costs allocated thereto). In the event of such an election not to participate in one or more exploration well(s), HES will have no rights or obligations with respect to such well(s) and facilities and the production attributable thereto, with the Prospect in which HES participates being defined by the proviso in Section 1.2(x). 5.5	HES Share of Prospect Costs and Revenues Provided that HES has elected to participate in a Prospect in accordance with the provisions of Article 5.4(a) above, HES shall pay the HES Share of costs and expenses and shall receive the HES Share of revenues, as follows: 5.5.1	The Initial Participation Payment (a) 	HES shall pay MOXY for the HES Share of the costs and expenses for lease acquisition, exploration, development and operating costs incurred during all periods prior to the Election Point, regardless of whether MOXY has received all invoices, which costs and expenses shall include but are not limited to all payments or reimbursements made for: (i) the acquisition of rights and interests in, and facilities and platforms associated with, the Prospect (including all costs, expenses and financial obligations, including without limitation, such items as lease bonuses or purchase costs and rentals, bonds, and pre-paid reclamation costs but excluding such items as debt service and related costs), (ii) the acquisition, licensing and/or processing of geological, geophysical and other data and analyses obtained by MOXY for its evaluation of the Prospect (including the actual retainers for MOXY's technical consultants including but not limited to CLK Company, L.L.C.); (iii) the conduct of surveys, site preparation and permitting; (iv) the securing of access or surface or facilities use rights and/or platform space; and (v) the drilling, logging, coring and testing, as applicable, of the well(s) constituting the Initial Test Well including temporary abandonment or completion costs. All prior exploration expenditures, lease and land acquisition costs, seismic data costs and other similar items relating to the lease(s) on which the Prospect is located shall be charged to the Prospect unless MOXY has a prior or concurrent development of proven reserves on a portion of the lease(s) that is not part of the Prospect, in which event an appropriate allocation of costs shall be made. With respect to the package of properties acquired by MOXY from Shell Offshore Inc. in December 1999, MOXY shall, following consultation with HES, make a reasonable and equitable allocation of the costs of such acquisition to the properties covered thereby in accordance with generally accepted accounting principles. With respect to the amount of the reimbursements to which MOXY is entitled in accordance with the foregoing provisions of this Section 5.5.1(a), to the extent that HES is obligated to obtain a data use license for the activities contemplated under this Agreement related to a Prospect with respect to the same geophysical or seismic data as to which MOXY already holds a license, and HES pays licensing fees in order to obtain the required license, HES will receive a credit for the amount of such data license fees up to but not exceeding the amount of the reimbursement to which MOXY would otherwise be entitled for data license costs on the Prospect in question for the same geophysical or seismic data. MOXY shall issue an invoice(s) to HES following its Acceptance under Section 5.4 for the costs and expenses described above and constituting the Initial Participation Payment. Within ten (10) days following HES's receipt of any such invoice, HES shall pay to MOXY or to the Collateral Account for the benefit of MOXY as provided in Section 6.2(a)(ii), whichever is appropriate, the amount of such invoice by wire transfer of immediately available funds. In order to facilitate the calculation provided for in Section 6.2(a)(ii), each MOXY invoice shall list separately: (i) the development costs, and (ii) all other costs. The amounts invoiced by MOXY under this paragraph shall be subject to adjustment to take into account deferred billings by suppliers and service providers and other appropriate adjustments following the issuance of the original invoice. (b) 	The HES Share of these costs and expenses shall be equal to 20% of the aggregate costs and expenses of all MOXY Program Participants, but without reduction for the benefit of any disproportionate cost sharing by Laid Off Interest Participants. (c) 	HES shall have the right to audit the above described costs and expenses in accordance with the provisions of the applicable COPAS accounting procedure. 	5.5.2	Development and Operating Costs (a) 	Before Prospect Pay-Out, the HES Share shall be equal to 20% of the aggregate costs and expenses incurred on behalf of all MOXY Program Participants associated with the Prospect during all periods following the Election Point, excluding costs and expenses allocable to (i) any parties holding interests in the Prospect who are not MOXY Program Participants and (ii) the working interest of a farm-out party who elects to participate in the development of the Prospect. However, in any case, HES shall bear only 6% of the Plugging and Abandonment costs relating to a Prospect that are incurred on behalf of all MOXY Program Participants; except that where such Plugging and Abandonment costs are incurred prior to Prospect Pay-Out, HES shall bear 20% of the Plugging and Abandonment costs relating to any well on the Prospect that are incurred on behalf of all MOXY Program Participants and 6% of all other Plugging and Abandonment costs that are incurred on behalf of all MOXY Program Participants. (b) 	After Prospect Pay-Out, the HES Share of the costs and expenses shall be reduced from 20% to 6% of any costs and expenses that are incurred on behalf of all MOXY Program Participants. 5.5.3	Revenues (a) 	Before Prospect Pay-Out, the HES Share of revenue shall be equal to 20% of the revenue attributable to the working interests of all MOXY Program Participants in the Prospect (subject to the royalties, overriding royalties, net profits, and other burdens and conditions applicable to such interests, including, but not limited to, the overriding royalty payable to MOXY's technical consultant, CLK Company, L.L.C.). However, the HES Share of revenue before Prospect Pay-Out shall not be based on the revenue allocable to (i) any parties holding interests in the Prospect who are not MOXY Program Participants; (ii) any farm-out party who elects to participate in the development of the Prospect; and (iii) a farm-out party having a working interest in the Prospect, after payout is achieved under such farm-out (subject to any applicable burdens and conditions). (b) 	After Prospect Pay-Out, the HES Share of revenue shall be 6% of the revenue attributable to the working interests of all MOXY Program Participants in the Prospect (subject to such royalties, overriding royalties, net profits, and other burdens and conditions applicable to such interests). However, the HES Share of revenue after Prospect Pay-Out shall not be based on the revenue allocable to (i) any parties holding interests in the Prospect who are not MOXY Program Participants; (ii) any farm-out party who elects to participate in the development of the Prospect; and (iii) a farm-out party having a working interest in the Prospect, after payout is achieved under such farm-out (subject to any applicable burdens and conditions). As used in this Section 5.5.3, the words "burdens and conditions" shall be those burdens and conditions affecting MOXY's ownership interest in the Prospect. 5.5.4	Reinstatement of Prospect Pay-Out The Parties acknowledge the possibility of a situation where Prospect Pay-Out occurs prior to the completion of a significant portion of the development activities contemplated in the Development Plan for a Prospect. In the event this situation occurs and MOXY has previously advised HES of the possibility of such occurrence in the Development Plan, the pre- Prospect Pay-Out status and interests of the Parties shall be reinstated and the further costs will be assessed against Prospect Pay-Out, and the subsequent revenues (including the revenues from both the original development, as well as the new development) will be combined for Prospect Pay-Out purposes. 5.5.5	Plugging and Abandonment Costs For Certain Properties In the event that HES elects to participate in a Prospect on Eugene Island Block 193, Eugene Island Block 208, or Eugene Island Block 215 (the "Blocks"), HES shall bear 20% of the aggregate costs and expenses of all MOXY Program Participants (but without reduction for the benefit of any disproportionate cost sharing by Laid Off Interest Participants) of the Plugging and Abandonment costs that MOXY has obligated itself to incur in connection with the acquisition from Texaco of rights in these Blocks, it being understood and agreed that, as to these Blocks: i) the HES Share of any Plugging and Abandonment costs is in the nature of the acquisition costs described in Section 5.5.1(a)(i), and ii) MOXY shall charge HES for these Plugging and Abandonment costs (based upon MOXY's book value of the Plugging and Abandonment liability in accordance with generally accepted accounting principles at the time of the HES election) as part of the amounts included in the invoice(s) for the Initial Participation Payment. HES shall be relieved of all further responsibility for Plugging and Abandonment costs associated with any such wells, platforms or other facilities upon its payment of its share thereof through its Initial Participation Payment. The Parties will apply the same formula with respect to the Plugging and Abandonment costs of any wells, platforms or other facilities existing at the time of acquisition on Prospects where all or a substantial part of the consideration for acquisition is MOXY's agreement to assume Plugging and Abandonment costs associated with such wells, platforms or other facilities. 5.6	Form of Operating Agreement, Elections by Parties (a) 	The Operating Agreement, attached hereto as Exhibit "E", as appropriately modified to conform to the requirements of each Prospect, shall apply to the development of those Prospects in which HES has elected to participate. However, for those Prospects where another form of operating agreement is otherwise applicable (an "Alternative Operating Agreement"), then the terms of such Alternative Operating Agreement shall apply as between MOXY and HES, and HES shall have the right to exercise elections thereunder, except as otherwise provided in this Agreement. The Parties acknowledge that HES will never be a direct party to any Alternative Operating Agreement and that, in the case of a Prospect where an Alternative Operating Agreement applies, HES's rights and obligations will be defined by this Agreement and the Alternative Operating Agreement. Moreover, as between MOXY and HES, to the extent that the terms of this Agreement conflict with the terms of the Operating Agreement or an Alternative Operating Agreement, the terms of this Agreement shall control. (b) 	HES commits to participate in any and all operations that relate to the implementation of the Development Plan (as originally proposed or as revised by the Parties) for the Prospects in which HES has elected to participate, except (i) where a proposed operation represents a material alteration in the scope of the Development Plan (as originally proposed or as revised by the Parties) or (ii) where the expenditures on any operation that are approved by an AFE exceed the original AFE amount by 100% or more. For clarification, the drilling of any well, the setting of any facilities, the re-working or re-completion of any well, or similar significant expenditures which are proposed to be carried out prior to Prospect Pay-Out and were not included in the Development Plan (as originally proposed or as revised by the Parties) shall be deemed to be a material alteration to the scope of the Development Plan. In those cases, HES shall be entitled to non-consent the additional expenditures for such operation. Where HES determines to non-consent pursuant to (i) or (ii) above, it automatically forfeits and shall be deemed to have assigned to MOXY, without compensation, its interest in such operation (though not in the Prospect). Where HES's decision to non-consent is based on the option provided in sub-part (ii) above, then the amount that HES expended on the operation, before it made the non-consent election, shall not constitute a part of the total expenditures for purposes of calculating Prospect Pay-Out. Notwithstanding the above, HES shall be obligated to participate in those operations for which a non-consent election is not applicable under the applicable Operating Agreement or Alternative Operating Agreement, including, but not limited to, Plugging and Abandonment operations. In the event that (i) an Alternative Operating Agreement applies, and (ii) MOXY advises HES that it plans to decline to participate in an operation thereunder, then MOXY shall offer HES the opportunity to participate in such operation in accordance with the terms of the Alternative Operating Agreement by bearing and paying the share of costs of such operation attributable to the interests of both HES and MOXY (excluding the interests of any MOXY Program Participants who may be separately participating in such operation). Should HES elect to participate on this basis before Prospect Pay-Out, then MOXY shall, on HES's behalf, elect to participate in such operation under the Alternative Operating Agreement, and MOXY shall automatically forfeit and shall be deemed to have assigned to HES, without compensation, its interest in such operation only. The costs of such operation incurred by HES and the revenues therefrom shall not be credited toward Prospect Pay-Out for that Prospect. Should HES elect to participate on this basis after Prospect Pay-Out, then MOXY shall, on HES's behalf, elect to participate in such operation under the Alternative Operating Agreement, and the applicable non-consent penalty shall apply with respect to that operation as between MOXY and HES. For purposes of this Section 5.6(b), the term "operations" means any activity (including any purchase) that is customarily subject to approval under an Authority for Expenditure under the applicable Operating Agreement. (c) 	Except as otherwise expressly provided in this Agreement, the rights and obligations of HES under this Agreement as well as the above provisions regarding the conditions associated with the ownership of oil and gas interests shall be subject to the provisions of all agreements entered into between MOXY and third parties governing such interests. The foregoing language of this paragraph (c) is not intended to allow MOXY to take actions which benefit MOXY while adversely affecting the interests of HES. 5.7	 HES's Interest Not Reduced 	After commencement of drilling of any Initial Test Well, MOXY shall not reduce the ********* (as described in Section 5.9) in the Prospect to which HES would be entitled at the time of an Election Point Notification without HES's prior written approval, unless required to do so by agreements existing at the time of such commencement; provided, however, if that Initial Test Well does not establish oil or gas reserves sufficient for commercial development (using MOXY's generally applicable parameters for commercial development), then the above described protection of HES's Share will no longer be applicable; and provided further that HES's Share shall not be reduced for the interest of a Laid Off Interest Participant whose status is determined under Section 1.2(o)(ii). 5.8	HES's Obligations Regarding Prospects in Which it Has Declined to Participate For all Prospects in which HES declines to participate, HES will: (i) continue to maintain the confidentiality of all data and information provided or to which it has had access, as set forth in Section 8.1, and (ii) not acquire any interests in such Prospect without offering such interest to MOXY at HES's actual cost, for a period of three years following the termination of this Agreement. However, subpart (ii) above shall not apply with respect to any such Prospect for which (x) HES has declined to participate and (y) HES wishes to undertake an "integrated solutions" project which would enable HES to acquire an interest in such Prospect; provided that HES obtains MOXY's written concurrence that such arrangement will not cause MOXY to violate the terms of any agreements that are binding on MOXY, which concurrence shall not be unreasonably withheld by MOXY. 5.9	Nature of HES's Interest 	HES shall hold a ********* with respect to those portions of any lease(s) included in a Prospect in which HES elects to participate and makes the Initial Participation Payment. Notwithstanding the fact that HES may not hold legal title to its interest in said lease(s), HES will acquire *********. In addition, HES shall look only to the mineral proceeds and income from its ******** for the return of its investment. This ********* is intended to be an economic interest, as defined in U.S. Treasury Regulation Section 1.611-1(b). Notwithstanding HES's ********* pursuant to the terms of the applicable operating agreement, HES designates MOXY as its marketing agent for the time being. Pursuant to this agency, MOXY shall have full authority to administer each such interest for the benefit of HES, including, but not limited to, the authority to (i) market and sell the oil, gas, and other hydrocarbons attributable to such interest in accordance with sound oil and gas marketing practices and consistent with the standards upon which it markets and sells its own production of like quantity and quality and under similar circumstances; (ii) hold in trust for, and remit to HES any proceeds it receives attributable to the sale of such hydrocarbons in the month following the month that MOXY receives the proceeds; and (iii) provide access to HES to review all contracts, agreements or other documents executed under the authority granted in this Agreement and to audit such activities at such time as requested by HES. MOXY will obtain HES's consent prior to entering into any sales contract that has a term exceeding one year. 	In connection with HES's ********* as set forth above, and to better assure HES that its ********* will be protected from MOXY's creditors, MOXY agrees that such ********* shall be secured by a first priority lien on such ********* in favor of HES. Such lien shall be evidenced by a Deed of Trust or Mortgage in the forms attached hereto as Exhibit "F-1" and Exhibit "F-2", as appropriate, with a Financing Statement in the form attached hereto as Exhibit "G-1" or Exhibit "G-2", as appropriate. Said Deed of Trust/Mortgage and Financing Statement shall be executed by MOXY and delivered to HES simultaneous with the receipt by MOXY of the Initial Participation Payment for the Prospect and may be recorded immediately thereafter by HES. The foregoing provisions of this paragraph shall be inapplicable to Prospects where MOXY ********* working interest to HES rather than HES holding a *********. 	Notwithstanding any of the foregoing, in the event a preferential right to purchase is determined to exist with respect to HES's interest hereunder in a Prospect and such preferential right is exercised on any Prospect in which HES has elected to participate, all revenues received by MOXY from the exercise of such preferential right to purchase shall be paid to HES, BUT ONLY TO THE EXTENT required to reimburse HES for the amount of the Initial Participation Payment made by HES and for other costs and expenses subsequently paid by HES under the Participation Agreement or applicable operating agreement for such Prospect and, in the event HES has decided to participate in the Prospect where MOXY has either provided insufficient information to HES regarding the applicable preferential right to purchase or where MOXY has provided HES with a misinterpretation of the applicable preferential right provision(s), MOXY shall also pay to HES interest on the above described reimbursable amounts calculated from the date such amounts were paid by HES through the date of reimbursement by MOXY at the published prime commercial lending rate of Chase Manhattan Bank for loans in New York in effect from time to time (such rate to be adjusted simultaneously with each change in such prime commercial lending rate) and calculated on the basis of a 365-day year; and MOXY shall have no other obligation or liability to HES with respect to any such Prospect or as a result of the exercise of such preferential right to purchase. 5.10	Drainage Should MOXY participate in a well or wells outside the Prospect area (such well or wells being referred to as "Drainage Well(s)") which Drainage Well(s) are completed in a zone or zones that are producing or are behind pipe in a Prospect well and in which HES owns rights hereunder, then MOXY and HES shall, in good faith, agree on measures which protect HES's interest in the reserves which would have been produced from the Prospect well in the absence of the Drainage Well(s) (for instance, the formation of a unit that includes both wells with participation based on the individual well reserves). ARTICLE 6 GUARANTY PROVISIONS 6.1	Halliburton Guaranty of Tranche B Indebtedness (a)	Commitment. Halliburton is guaranteeing on a senior basis (the "Guaranty"), MOXY's obligations, including principal, interest and fees thereof, under Annex I (the "Tranche B Credit Facility") of the Amended and Restated Credit Agreement dated as of the date of this Agreement among MOXY, Chase Bank of Texas, National Association (together with successor agents, the "Agent") and the Lenders (the "Lenders") signatory thereto (the "Credit Agreement"). The principal balance of the Tranche B Credit Facility shall not exceed an outstanding balance of the lesser of $50,000,000 or the amount determined in accordance with Section 6.2. The Tranche B Indebtedness will be subordinated to MOXY's Senior Debt (initially the Tranche A Indebtedness) on the basis set forth in the Tranche B Credit Facility. Halliburton agrees that it will not amend, modify or consent to any waiver of the Guaranty without the prior written consent of MOXY, if such amendment, modification or waiver would reduce the amount available to MOXY under the Tranche B Credit Facility. (b)	Guaranty Fee. While the Guaranty is in effect, MOXY shall pay to Halliburton, within fifteen days of the end of each calendar quarter, a guaranty fee equal to the product of (a) the sum of (i) one percent (1%) per annum on the average outstanding balance of the Tranche B Indebtedness during such quarter plus (ii) one half percent (1/2%) per annum on the average available but unused portion of the Aggregate Tranche B Commitments, during such quarter, and (b) a number, the numerator of which is the number of days in the quarter and the denominator of which is 360. MOXY will provide Halliburton with such information as is necessary to substantiate the calculation of the fee. 6.2	Amount Guaranteed (a)	Aggregate Tranche B Commitments Reduction. The Aggregate Tranche B Commitments will be reduced in each of the following circumstances: (i) 	If MOXY makes voluntary reductions to the Aggregate Tranche B Commitments pursuant to Section 2.03(b) of the Tranche B Credit Facility. (ii)	Each time HES pays to MOXY (or to the Collateral Account for the benefit of MOXY) an Initial Participation Payment in accordance with Article 5, MOXY shall reduce the Aggregate Tranche B Commitments by the amount of such Initial Participation Payment reduced by the amount attributable to development costs. MOXY hereby directs HES to make such payments to the Collateral Account described in Section 2.07(c) of the Tranche B Credit Facility. (iii)	On the fourth Business Day following December 31, 2001, the Aggregate Tranche B Commitments shall be reduced to an amount equal to the Aggregate Maximum Tranche B Credit Amounts on such date. (iv)	Notwithstanding anything herein to the contrary, the Aggregate Tranche B Commitments shall be reduced by MOXY to zero on December 31, 2003. 	(b)	Aggregate Maximum Tranche B Credit Amount Adjustment. The Aggregate Maximum Tranche B Credit Amount will be adjusted within four (4) Business Days after each Shortfall Measurement Date to an amount equal to $50,000,000 minus the Shortfall, if any, on the date of such calculation minus the amount by which the Aggregate Tranche B Commitments have been reduced as of such date by (i) MOXY's voluntary reduction or termination of Aggregate Tranche B Commitments under Section 2.03(b) of the Tranche B Credit Facility, and (ii) amounts HES has paid to MOXY under Section 2.03(c) of the Tranche B Credit Facility. (c)	Mandatory Repayments of the Tranche B Indebtedness. In the event the aggregate principal amount outstanding under the Tranche B Indebtedness ever exceeds either the Aggregate Maximum Tranche B Credit Amount or the Aggregate Tranche B Commitments, MOXY agrees to promptly pay to the Lenders of the Tranche B Indebtedness any amounts required such that the aggregate principal amount outstanding under the Tranche B Indebtedness does not exceed either the Aggregate Maximum Tranche B Credit Amount as adjusted pursuant to Subsection (b) above or the Aggregate Tranche B Commitments as reduced pursuant to Subsection (a) above. 6.3	Reimbursement Obligations 	Upon the terms and subject to the conditions set forth in that certain Indemnity Agreement by and between MOXY and Halliburton of even date herewith, MOXY agrees to pay Halliburton an amount equal to any amount paid by Halliburton pursuant to the Guaranty plus costs and interest on such amounts as specified in the Tranche B Credit Facility. 6.4	Information to be Provided by MOXY to Halliburton Until the Tranche B Credit Facility is terminated, MOXY, at its expense, shall provide to Halliburton: (a) copies of all material, correspondence and documentation that MOXY provides to the agent or the lenders pursuant to any Senior Debt and the Tranche B Credit Facility, (b) all correspondence and documentation received by MOXY from the agent or lenders pursuant to any Senior Debt and the Tranche B Credit Facility, (c) a written report which sets forth the principal balance outstanding and the letter of credit exposure under both any Senior Debt and the Tranche B Credit Facility as of each calendar month, including the borrowings and repayments during such month, and (d) notice of any borrowings under any Conventional Senior Debt that results in amendment of the Tranche B Credit Facility Articles VIII and IX covenants and any modification of Conventional Senior Debt covenants incorporated into the Tranche B Credit Facility and copies of all such covenants and amendments. The documents required by (a) and (b) will be mailed within three business days of dispatch or receipt of the original correspondence, as applicable. The report required by (c) will be delivered on the third business day of the month succeeding the month for which the report is prepared. The notice and copies required by (d) will be delivered within three business days of the applicability of the Conventional Senior Debt covenants to the Tranche B Credit Facility or the amendment of such covenants. 6.5	When Guaranty Amount Reduces to Zero; Election Rights Terminate 	Notwithstanding anything in this Agreement to the contrary, MOXY's obligation to offer to HES and HES's right to make Elections shall terminate on the earlier of: (i) the expiration of the Term (as extended for purposes only of MOXY's obligations to issue Election Point Notifications on certain Prospects, where applicable, by the six month extension period described in the introductory paragraph of Section 5.3 and, in connection therewith, for purposes of HES's participation rights arising out of any such Election Point Notifications), or (ii) the date following the date on which the maximum Guaranty amount reduces to zero by operation of Section 6.2, if applicable. 6.6	Halliburton Acknowledgement 	Halliburton expressly acknowledges that it has reviewed the Tranche B Security Documents and the Tranche B Credit Facility, including, without limitation, Sections 12.04, 12.19 and Sections 3.03 through 3.18 thereof, that it agrees to all such provisions and that it authorizes and consents to the waivers and releases provided in Sections 3.12 and 12.04(b)(i) of the Tranche B Credit Facility by the Agent and the Lenders without the need for any further consent, approval or other action on the part of Halliburton. 6.7	Legal Opinion 	As a condition precedent to the execution and delivery by Halliburton of the Guaranty, MOXY will cause Jones, Walker, Waechter, Poitevent, Carrere & Denegre, L.L.P. to deliver to Halliburton a legal opinion addressed to Halliburton in the form delivered to the Agent and the Lenders pursuant to the Credit Facility. 6.8	Certificates to be Delivered to Agent 	MOXY covenants and agrees to deliver to the Agent under the Tranche B Credit Facility in a timely manner all certificates required by Section 2.03(c) and (d) of the Tranche B Credit Facility. 6.9	Representations and Warranties. MOXY represents and warrants that on the date hereof, (x) there are no wells being drilled, deepened, plugged back or reworked, and no other operations are being conducted with respect to Brazos A-19 for which consent is required under the applicable operating agreement (or for which operations other than normal operations of existing wells on Brazos A-19 are being conducted); and (y) there are no proposals currently outstanding (whether made by MOXY or any other party) to drill, deepen, plug back or rework wells, or to conduct any such other operations, or to abandon any wells on Brazos A-19 (nor are there any such proposals that have been approved either by MOXY or any other party, with respect to which the operations covered thereby have not been commenced). 6.10	Covenant With Respect to Brazos A-19. From the date hereof until the earlier of: (a) the payment in full of the Tranche B Indebtedness and the termination of all Tranche B Commitments, or (b) the release or subordination of the Liens on Brazos A-19 securing the Tranche B Indebtedness in accordance with the final two sentences of Section 12.19 of the Credit Agreement, MOXY will not, without prior written consent of HES, initiate any proposal to abandon any well producing from Brazos A-19 (or any property unitized therewith) so long as such well is capable (or is subject to being made capable through drilling, reworking or other operations in such well that would be commercially feasible to conduct based upon MOXY's reasonable judgment which in turn shall be based upon an economic evaluation of Brazos A-19 and the particular operation being considered) of producing oil, gas or other hydrocarbons or other minerals in commercial quantities (as determined in consultation with HES). In any case, the above described covenant of MOXY is not applicable to the permanent abandonment of the Brazos Block A-19 JC No. 1 Well. 6.11	Covenant Relating to Brazos A-19 Non-Consent Options. (a)	From the date hereof until the earlier of: (a) the payment in full of the Tranche B Indebtedness and the termination of all Tranche B Commitments, or (b) the release or subordination of the Liens on Brazos A-19 securing the Tranche B Indebtedness in accordance with the final two sentences of Section 12.19 of the Credit Agreement, for any operation relating to the drilling or completion of a well on Brazos A-19 (or any property unitized therewith) for which MOXY has determined to non-consent pursuant to the applicable operating or other agreement governing Brazos A-19 (the "Option"), MOXY shall, no later than ten (10) days (or no later than 24 hours in the event a rig is on location) prior to the expiration of the Option, notify HES of MOXY's intent not to exercise the Option (such declaration of intent not to exercise the option being hereinafter referred to as a "Notice of Non-Consent"). Upon receipt of a Notice of Non-Consent, HES shall have the right to elect to participate in the operation to the extent of MOXY's interest therein (an "Election to Consent"), subject to HES's obligation to fund the operation to the full extent of MOXY's funding requirements under the applicable operating agreement. HES may exercise an Election to Consent by providing notice of its Election to Consent to MOXY not later than 2 business days (i.e. excluding Saturdays, Sundays and Federal holidays) (or no later than 12 hours in the event a rig is on location) prior to the expiration of the Option. If HES fails to provide notice to MOXY of its Election to Consent prior to the applicable deadline above, HES shall be deemed to have elected not to exercise the Election to Consent for that drilling or completion operation. Upon timely receipt of HES's notice of Election to Consent, MOXY shall promptly exercise its Option with regard to the applicable drilling or completion operation for the benefit of HES as set forth below.
