NOW, THEREFORE, for the consideration, being the mutual benefits and advantages accruing hereunder, the sufficiency of which is hereby acknowledged, the Parties agree as follows: Article 1 - Interest of the Parties ----------------------------------- The costs, risk and liabilities associated with the exploration and development of the Contract Area and the Newfield Lease (including all wells, platforms, pipelines, facilities and equipment associated directly with the specified operations herein) and all oil and gas produced from wells drilled pursuant to the terms hereof, shall be borne and owned, subject to the terms and conditions set out herein, and unless otherwise agreed, by the Parties in accordance with the following percentage working interests ("Working Interests"): Party Working Interests ----- ----------------- Newfield 50.00000% Ridgewood 50.00000%* *Subject to an obligation to pay a disproportionate share of Initial Test Well costs to Casing Point, as further described in Article 3. Participation Agreement-Eugene Island Block 346/347 dated March 15, 2007 Newfield Exploration Company & Ridgewood Energy Corporation - 2 - Article 2 - Operating Agreement ------------------------------- 2.1 Newfield is designated as the Operator of the Contract Area and the Newfield Lease, and all operations conducted on the Contract Area and the Newfield Lease shall be performed in accordance with and shall be subject to the terms and provisions of this Agreement, the Option Agreement, the Farmout Agreement and the Operating Agreement attached hereto as Exhibit "C" ("Operating Agreement"). The Parties shall execute the Operating Agreement simultaneously with this Agreement. 2.2 Notwithstanding anything herein to the contrary, the non-consent penalties set forth in Article XII of the Operating Agreement shall not be applicable to drilling operations on the Initial Test Well, or substitute therefor, prior to the Parties drilling an Earning Well (as hereinafter defined). Article 3 - Initial Test Well ----------------------------- 3.1 On or before May 30, 2007, Newfield shall commence actual drilling operations for the Eugene Island 346 (OCS-G-14482) No. 7 Well at an approximate surface and bottomhole location of 6,150' FSL and 900' FWL of Eugene Island 346 ("Initial Test Well"). The Initial Test Well will be drilled in accordance with Newfield's AFE dated October 27, 2006, and shall be drilled to a proposed total depth of 12,890' TVD/MD, or to a depth sufficient to fully evaluate the "GA-1" Sand, whichever is lesser depth ("Contract Depth"). The "GA-1" Sand correlates to the shale interval which occurs at 10,550' MD (10,459' SSTVD) in the El 346, Anadarko Petroleum Corporation Well No. 1 ST-1 (OCS-G 14482). 3.2 As additional consideration for the opportunity to earn its Working Interest in the Contract Area, the Parties will pay the following percentages of the costs to drill the Initial Test Well to Casing Point (as described in Article 3.3 below): Newfield 0% Ridgewood 100% The dry hole well cost for the Initial Test Well is estimated to be $18,036,673.00 ("Dry Hole Cost") as outlined on the drilling authorization for expenditure ("AFE") for the Initial Test Well attached hereto as Exhibit "D". Ridgewood's disproportionate cost sharing will cease once cumulative costs and expenses for the Initial Test Well, and if drilled, the substitute well therefore, reach Casing Point or $18,000,000.00, whichever occurs first. Thereafter Newfield will bear its 50% and Ridgewood will bear its 50% share of subsequent costs, subject to the non-consent rights set out in the Operating Agreement. Participation Agreement-Eugene Island Block 346/347 dated March 15, 2007 Newfield Exploration Company & Ridgewood Energy Corporation - 3 - 3.3 Casing Point is defined as that point in time when the Initial Test Well, or substitute well therefor, has been drilled to the Contract Depth, and all open-hole logs and all appropriate tests have been performed and delivered to the Parties, and a recommendation is made to (i) set casing and complete the well, (ii) plug and abandon the well or (iii) conduct other operations as provided within the priority of operations outlined within the Operating Agreement. 3.4 If the Initial Test Well is either, i) unable to reach the Contract Depth due to encountering domal material, heaving shale, saltwater, salt or other impenetrable substance, or suffers any adverse condition (mechanical, structural, stratigraphic or otherwise) in drilling said well, which substance or condition cannot be overcome at a reasonable cost by means considered customary or ordinary in the industry; or, ii) plugged and abandoned as a dry hole, then any Party shall have the right to propose a substitute well in the same manner as provided for and defined in the Farmout Agreement. Ridgewood shall have the option, but not the obligation, to participate in such substitute well; however, if Ridgewood elects not to participate in a substitute well, it shall forfeit its rights under this Agreement, and in the Farmout Agreement. If actual drilling operations are commenced on the substitute well within ninety (90) days from the date of rig release of the Initial Test Well, then said well shall be considered the Initial Test Well for purposes of this Agreement. Article 4 - Assignment and Assumption of Rights ----------------------------------------------- 4.1 Newfield will obtain Apache's written consent to assignment, by Newfield to Ridgewood, of a 50.00% interest in the rights, duties and obligations conferred by the Option Agreement and Farmout Agreement. 4.2 Upon Ridgewood's participation pursuant to the terms and conditions set forth herein and in the Farmout Agreement, and upon the Parties drilling an Earning Well (as defined in the Farmout Agreement) and satisfying the Earning Requirements defined and set out in the Farmout Agreement, the Parties who participated in the Earning Well, and the full satisfaction of the Earning Requirements, shall receive from Apache, an assignment of their respective Working Interest shares of the operating rights interest in the Apache Lease within the Contract Area, from the surface down to the base of the deepest productive interval in said well and its stratigraphic equivalent, plus one hundred (100) feet. In addition, Ridgewood shall be entitled to an assignment of fifty percent (50%) of the Record Title interest in the entirety of the Newfield Lease provided it participates in the drilling of the Initial Test Well or substitute(s) thereof to Contract Depth as defined in the Farmout Agreement. 4.3 The interest assigned to Ridgewood pursuant hereto shall be subject only to the federal 1/6th royalty (subject to any applicable royalty relief granted by the Minerals Management Service), and the Apache ORRI, and shall be free and clear of any other overriding royalty interest, production payments, or other burdens on production.

Well Proposal. a. Within thirty (30) days of full execution of this Option Agreement, Newfield shall hold a technical review meeting in its offices and provide Apache a prospect presentation, detailing Newfield's geological/geophysical evaluation of the Contract Area, including any prospect Newfield has identified and whether or not Newfield plans to drill same on the Contract Area. Said presentation shall include a review of Newfield's licensed seismic data which shall be subject to any restrictions imposed on the data to be shown to Apache by any applicable confidentiality, license or other agreement, under the terms of the Confidentiality Agreement attached hereto as Exhibit "A". b. Within thirty (30) days following the technical review, and after due consultation with Apache, Newfield may propose to Apache the drilling and evaluating of a well (the "Initial Test Well") at a location of its choice on the Contract Area to a minimum depth of 12,000' TVD, or a depth sufficient to test the equivalent shale interval as seen in the El 346 OCS-G 14482 No. 1 ST-1 EXHIBIT "A" Attached to and made a part of that certain Participation Agreement dated effective March 15, 2007, by and between Newfield Exploration Company and Ridgewood Energy Corporation Newfield Exploration Company (281) 847-6000 Fax (281) 405-4242 Apache Corporation September 14, 2006 Page 2 Well, whichever is the lesser depth ("Contract Depth"), and shall provide Apache with a proposed location, objective, cost estimate, AFE and well plan. The proposed target "GA-1" Sand should occur in a correlative position equivalent to a shale interval which occurs at 10,550' MD (-10,459' SSTVD) in the EI 346, Anadarko Petroleum Corporation Well No. 1 ST-1 (OCS-G 14482). Should Newfield not propose the Initial Test Well as provided in this paragraph, this Option Agreement will terminate on the thirtieth (30th) day after the technical review provided for in Paragraph l.a above. c. If Apache elects to participate pursuant to Article 2.a below and Newfield elects to process its production from the Initial Test Well or its substitute at Apache facilities or if the Initial Test Well or its substitute is drilled from an Apache owned platform, Newfield would drill and complete such well and thereafter Apache would become the operator. If Apache elects to farmout pursuant to Article 2.b below and the Initial Test Well is drilled from an Apache operated platform, Newfield would drill and complete such well and Apache would operate the production as a contract operator. 2. Apache Option. Apache shall have thirty (30) days from receipt of the proposal under Paragraph 1(b) within which to elect in writing to either: a. To participate in the drilling of the initial Well. If Apache decides to participate, then: (i) The Initial Test Well, subsequent wells and related development costs, if any, within the Contract Area, shall be funded fifty percent (50%) by Newfield and fifty percent (50%) by Apache; and, (ii) If the Initial Test Well, or its Substitute Well (as described in 4.a), is timely drilled to Contract Depth and qualifies as a well capable of producing in paying quantities in accordance with 30 CFR 250.115 or 30 CFR 250.116 and Newfield elects to complete said well, with the intention to produce hydrocarbons to sales (an "Earning Well"), Newfield shall earn an assignment of fifty percent (50%) of Apache's operating rights in the portion of the EI 346 Acreage comprising the Contract Area down to total depth drilled in said well and its stratigraphic equivalent plus one hundred (100) feet. Likewise, Apache shall be entitled to an equivalent assignment of operating rights in and to the Newfield Acreage; and, (iii) All operations will be governed by a mutually acceptable Operating Agreement covering the Contract Area limited in depth from the surface to the Contract Depth or to the top of salt, whichever is shallower, under which Newfield and Apache shall own their respective interests as set out above. The operator would be in accordance with Article 1.c. above. b. Or to farmout to Newfield the EI 346 Acreage within the Contract Area on the following terms and conditions: (i) Newfield shall be designated Operator of the Contract Area, except as to aliquots and/or wellbores associated with Apache's existing Eugene Island Block 346 production operations. In the event the Initial Test Well is drilled from an Apache owned platform, Apache would be designated contract operator of the production in accordance with Article l.c. above; Apache Corporation September 14, 2006 Page 3 (ii) If the Initial Test Well, or its Substitute Well (as described in 4.a.), is an Earning Well, Newfield shall earn an assignment of one hundred percent (100%) of Apache's operating rights in the EI 346 Acreage from the surface down to total depth drilled in said well and its stratigraphic equivalent plus one hundred (100) feet. Apache shall retain a five percent of six-sixths (5.0% of 6/6ths) overriding royalty interest ("ORRI") in the EI 346 Acreage as to those depths included in the assignment of operating rights earned by Newfield. Newfield will also assign to Apache a five percent of six-sixths (5.0% of 6/6ths) ORRI in the Newfield Acreage from the surface down to a total depth drilled in the Earning Well and its stratigraphic equivalent plus one hundred (100) feet. In the event Apache owns less than one hundred percent (100%) of the record title and/or operating rights interest in the EI 346 Acreage comprising the Contract Area, Apache's retained ORRI shall be proportionately reduced; (iii) Newfield will have the option to earn rights to deeper depths in the Contract Area by commencing drilling operations on or before six (6) months from the date on which the drilling rig is released from the Earning Well. Any such additional well to earn the deeper rights shall be drilled in accordance with the terms and conditions of this Option Agreement, except that the Contract Depth shall be revised, as appropriate. Failure to drill or participate in the drilling of an optional deeper test well during said period shall result in loss by Newfield of any option to earn such deeper rights. Notwithstanding anything herein to the contrary, Newfield shall not have the right to earn any depths below the top of salt and any farmout agreement entered into between Apache and Newfield shall be limited to those depths from the surface to the Contract Depth or the top of salt whichever is shallower. 3. Production Handling. Newfield, subject to capacity limitations of the facilities located on Apache's Platform, shall have the option, but not the obligation, to process its Contract Area production through Apache's existing production handling facilities located on the Platform, under the terms of a mutually acceptable production handling agreement which shall incorporate, among other provisions, processing and handling rates of $.15/mcf for gas, $1.00/bbl for oil and condensate, $1.00/bbl for water, and $.05/mcf per stage of compression, if available and a monthly contract operating fee of $10,000.00 for the first well and $5,000.00 for each additional well for a manned -facility or $12,500.00 for the first well and $5,000.00 for each additional well for an unmanned facility (collectively "Fees"). In any month in which there is production from the Contract Area, if the Fees do not equal or exceed fifteen thousand dollars ($15,000.00) in any calendar month, then a minimum fee of fifteen thousand dollars ($15,000.00) shall be charged to Newfield in lieu of fees based upon throughput for such month, regardless of actual throughput. In any month in which there is no production from the Contract Area, the minimum monthly fee shall not exceed ten thousand dollars ($10,000.00). The Fees shall be adjusted on the first day of April of each year by multiplying the rate currently in use by the percentage increase in the average weekly earnings of Crude Petroleum and Gas Production Workers for the last calendar year compared to the calendar year preceding as shown by the index of average weekly earnings of Crude Petroleum and Gas Production Workers as published by the United States Department of Labor, Bureau of Labor Statistics. The increase in the Fees will be prorated to the date of initial production during the first year of operation. Notwithstanding the above, in the event Apache determines in its sole judgment Apache Corporation September 14, 2006 Page 4 that it is uneconomic to continue to process Newfield's production at Apache's production facilities, then Apache may discontinue the production handling services upon sixty (60) days written notice to Newfield and the parties will attempt to negotiate a sale or platform sublease agreement to allow continued Contract Area production. 4. General Terms and Conditions. Whether Apache agrees to participate or to farmout under Paragraph 2, the parties agree that: a. Newfield will have the option to commence the drilling of another well (a "Substitute Well") in the event the Initial Test Well is unable to reach Contract Depth due to conditions beyond Newfield's control as a prudent operator, within ninety (90) days of the date the rig is released on the well. If the Initial Test Well, or any Substitute Well therefor, reaches Contract Depth but does not qualify as an Earning Well, Newfield shall have ninety (90) days after the plugging and abandonment of such well to commence the drilling of an additional well in an attempt to earn an interest in the Contract Area; and, b. Subject to weather conditions, rig availability and acquiring all necessary permits, Newfield must commence, or cause to be commenced, the drilling of the Initial Test Well within one hundred eighty (180) days after execution of this Option Agreement at a location of its choice on the Contract Area. Drilling of the Initial Test Well shall thereafter continue in a workmanlike manner to Contract Depth with the option to drill the Initial Test Well or subsequent wells to a deeper depth. Newfield's only penalty for failure to commence the Initial Test Well as provided herein shall be loss of all rights to earn an interest in the EI 346 Acreage. c. Newfield shall not earn an interest in nor assume any additional liability associated with any well, platform, facility, or pipeline currently located on the Contract Area, except as may be provided under any production handling agreement or platform sublease agreement that may be entered into pursuant to this Option Agreement. Apache shall retain one hundred percent (100%) of its rights and interests in any such well, platform, facility or pipeline currently located on the EI 346 Acreage including the obligation to abandon same. d. Newfield and Apache, if Apache elects to participate pursuant to Article 2. (a) above, shall not drill and produce, or cause to be drilled and produced, from the Contract Area any reserves that are being produced or capable of being produced by recompletion or other means of recovery from Apache's existing wells in the EI 346 Acreage. Likewise, Apache shall not drill and produce, or cause to be drilled and produced, any new wells on Eugene Island Block 346 which would compete with and drain reserves discovered by any wells drilled pursuant hereto on the Contract Area. Newfield shall not drill and produce or cause to be drilled and produced, any new wells on Eugene Island Block 347 which would compete with and drain reserves discovered by any wells drilled pursuant hereto on the Contract Area, e. Following Apache's election to farmout or participate in the drilling of the Initial Test Well, Newfield and Apache shall in good faith and in a timely manner negotiate and execute a comprehensive farmout agreement or operating agreement, as appropriate, consistent and in line with the terms hereof. Apache Corporation September 14, 2006 Page 5 f. The terms of this Option Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. No assignment shall be effective without the prior written approval of the non-assigning party, which approval shall not be unreasonably withheld. g.

INITIAL TEST WELL ----------------- Subject to rig availability, weather conditions and acquiring all necessary permits, Newfield will commence or cause to be commenced the drilling of the OCS-G 14482 Well No. 7 ("Initial Test Well"), on or before May 30, 2007, at a surface and bottomhole location of 6,150' FSL and 900' FWL of Eugene Island Block 346. The well will be drilled in accordance with Newfield's AFE dated October 27, 2006, and to a proposed total depth of 12,890' TVD/MD or to a depth sufficient to fully evaluate the "GA-1" Sand whichever is lesser depth ("Contract Depth"). The "GA-1" Sand correlates to the shale interval which occurs at 10,550' MD (10,459' SSTVD) in the El 346, Anadarko Petroleum Corporation Well No. 1 ST-1 (OCS-G 14482). Newfield shall not commence operations under this Agreement until Apache has received a fully executed copy of this Agreement, Newfield has been designated as Operator for conducting operations under this Agreement, and Newfield has acquired all the necessary permits. The Initial Test Well, Subsequent Well(s) (defined in Section II below) or any Substitute Well (defined in Section II below) drilled under the terms of this Agreement, shall be drilled free of any cost and/or liability of any kind or character to Apache, and all risk, liability, costs or expenses incurred in connection with drilling, testing, completing, operating and associated tie-in of said well or wells and/or plugging or abandoning said well or wells shall be borne solely by Newfield. Newfield shall not be obligated to drill or commence drilling the Initial Test Well or any other well under the terms of this Agreement. If Newfield fails Newfield Exploration Company February 28, 2007 Page 3 of 20 to timely commence drilling the Initial Test Well, Newfield will suffer no penalty other than the forfeiture of all rights under this Agreement. II. SUBSTITUTE WELL and SUBSEQUENT WELL(S) -------------------------------------- If, during the drilling of the Initial Test Well, or a Substitute Well (defined in this paragraph), Newfield is unable to reach Contract Depth due to conditions beyond Newfield's control, which in the opinion of a reasonably prudent Operator under the same or similar conditions would render further drilling impracticable or hazardous, and such condition prevents further drilling of the well, Newfield may commence a "Substitute Well", provided actual drilling of this Substitute Well is commenced within ninety (90) days after release of the drilling rig used for the Initial Test Well or any Substitute Well, and is drilled pursuant to all the terms and provisions of this Agreement applicable to the well for which it is substituted. If the Initial Test Well or any Substitute Well therefore, reaches Contract Depth but does not qualify as an Earning Well as described in Section III below, Newfield shall have the continuing right to drill "Subsequent Well(s)" on the Contract Area provided that each such Subsequent Well shall be subject to all the terms and provisions of this Agreement, and further provided that Newfield commences actual drilling operations on such Subsequent Well within ninety (90) days from plugging and abandonment of the prior well. In the event Newfield does not commence a Substitute Well or Subsequent Well within the applicable ninety (90) day period, this Agreement and Contract Area and all the terms and conditions contained herein shall terminate except for Newfield's obligation to plug and abandon any wells and/or platforms drilled and/or installed on the Contract Area by Newfield, Newfield will have the option to earn rights to deeper depths in the Contract Area by commencing drilling operations on or before one hundred eighty (180) days from the date on which the drilling rig is released from the Earning Well. Any such "Additional Well" to earn the deeper rights shall be drilled in accordance with the terms and conditions of this Agreement. Failure to drill or participate in the drilling of an Additional Well during said period shall result in loss by Newfield of any option to earn such deeper rights. Notwithstanding anything contained herein to the contrary, Newfield shall not have the right to earn any depths below the Deepest Earning Depth (defined in Section III below). Notwithstanding anything herein to the contrary, Newfield shall not have the right to drill any Substitute Well, Subsequent Well or Additional Well from Apache's Eugene Island Block 346 "A" platform ("Platform") located at 3,298' FNL and 3,543' FWL of Eugene Island 346. III. INTEREST EARNED --------------- Should Newfield drill the Initial Test Well or a Subsequent Well (or a Substitute Well for either the Initial Test Well or a Subsequent Well) to the Contract Depth, comply with the terms of this Agreement, and obtain MMS Newfield Exploration Company February 28, 2007 Page 4 of 20 determination that said well is a well capable of commercial production as provided under 30 CFR ss.250 115 or 116 and Newfield commences actual production within one hundred eighty (180) days of release of the drilling rig, or failing to obtain this determination, should Newfield elect to complete the well and equip same for the production of oil and/or gas in commercial quantities and Newfield commences actual production within one hundred eighty (180) days of release of the drilling rig, then said well shall be deemed the "Earning Well" and Apache shall execute and deliver an "Assignment" assigning to Newfield an interest in the operating rights to the Farmout Area. The Assignment shall: A. Be prepared by Apache and delivered to Newfield within sixty (60) days of a well being deemed an Earning Well, with the effective date of the Assignment being the date that the well is deemed an Earning Well. B. Be without warranty of title, statutory, express or implied, other than by, through and under Apache, and subject to all terms and conditions contained in all contracts (including but not limited to that certain Oil Purchase and Sale Agreement between Anadarko Petroleum Corporation and Texaco Trading and Transportation Inc. dated December 23, 1995) and agreements (recorded and unrecorded) attributable to the assigned interest, to the MMS reserved royalty interest, and the overriding royalty interest reserved by Apache as provided in Section III.(F) below and any overriding royalty interest or similar burdens affecting the Contract Area and filed of record as of December 5, 2006. Newfield acknowledges that it has reviewed Apache's files and is familiar with the Apache Lease and all agreements relating to the Farmout Area and takes cognizant of all matters relating to same. C. Be subject to the approval of the authorized officer of the MMS. D. Convey to Newfield one hundred percent (100%) of Apache's interest in and to the operating rights in the Farmout Area, from the surface down to the stratigraphic equivalent of the total depth drilled in the Earning Well plus one-hundred feet (100'), but in no event deeper than the top of salt. "Deepest Earning Depth" is defined as Contract Depth plus one hundred feet (100') or the top of salt, whichever is shallower. E. Reserve to Apache all rights to drill through the Farmout Area in order to explore, develop and/or operate all rights owned by Apache below the Contract Area or on lands pooled, or to be pooled, unitized or communitized therewith. F. Reserve to Apache an overriding royalty interest in the Apache Lease, including the Earning Well, of five percent of six-sixths (5.0% of 6/6ths) of all liquid and/or gaseous hydrocarbon substances produced and/or saved, either through testing or production on the Apache Lease. Simultaneously with Apache's execution of the Assignment, Newfield shall assign to Apache an overriding royalty interest of five percent of Newfield Exploration Company February 28, 2007 Page 5 of 20 six-sixths (5 0% of 6/6ths) of all liquid and/or gaseous hydrocarbon substances produced and/or saved, either through testing or production on the Newfield Lease. Both the overriding royalty reserved by Apache on the Apache Lease and the overriding royalty assigned to Apache on the Newfield Lease shall be collectively referred to as the overriding royalty interest ("ORRI"). G. Apache's ORRI shall be computed in the same manner and paid at the same time as the Lessor's royalty under the Apache Lease and the Newfield Lease and shall be free and clear of all royalty (other than MMS royalty), overriding royalty, and other burdens associated with production and all costs and expenses of drilling and production, except that the ORRI shall be charged with and bear its proportionate part of ad valorem, production, severance, excise, and other similar taxes on production. In the event the interest owned by Apache in the Farmout Area is less than a full leasehold interest, then the overriding royalty interest retained by Apache in the Apache Lease and the interest earned by Newfield shall each be proportionately reduced. H. Newfield shall not earn an interest in nor assume any additional liability associated with any well, platform, facility or pipeline currently located on the Farmout Area, except as provided in the PHA, as herein defined. Newfield shall not drill and produce or cause to be drilled and produced, from the Contract Area, any reserves that are being produced or capable of being produced from Apache's existing wells in the Contract Area or wells drilled in the Contract Area pursuant to this Agreement by recompletion of existing wells or the drilling of new wells for reserves that are capable of being produced in existing wells. Apache shall not drill and produce or cause to be drilled and produced, any new wells or the sidetrack of an existing well on the Contract Area, which would compete with and drain reserves discovered by any wells drilled hereunder pursuant to this Agreement. I. In the event Newfield fails to commence production from the Earning Well within one (1) year from rig release on the Earning Well then, unless Newfield can demonstrate a good faith effort on its part in attempting to initiate the sale of production from the Contract Area, the Contract Area shall terminate and Newfield will reassign to Apache any interest assigned to Newfield in the Farmout Area. J. Upon the total cessation of production from all wells drilled under this Agreement for a consecutive period of one hundred twenty days (120) days, during which period of time no operations are being conducted on the Contract Area in a good faith effort to re-establish production, the Contract Area shall terminate and at the request of Apache Newfield will re-assign to Apache any interest earned under this Agreement unless Newfield can demonstrate to Apache that reasonable circumstances exist which prohibit Newfield from conducting operations to re-establish production, but that Newfield is preparing to conduct such operations no later than one hundred fifty (150) days following such total cessation of production. Additionally, Apache will re-assign to Newfield any Newfield Exploration Company February 28, 2007 Page 6 of 20 overriding royalty interest previously assigned to Apache by Newfield pursuant to III. F. above. K. Any interest assigned from Newfield to Apache shall be free and clear of any liens, claims, encumbrances or any other burdens created by, through or under Newfield, but shall be subject to the interests reserved herein by Apache and all burdens of record as of December 5, 2006. IV. PRODUCTION HANDLING ------------------- Newfield, subject to capacity limitations of the facilities located on the Platform, shall have the option, but not the obligation, to process its production from the Contract Area ("Farmout Production") through Apache's existing production handling facilities located on the Platform, under the terms of a mutually acceptable production handling agreement ("PHA") which shall incorporate, among other provisions, processing and handling rates of $.15/mcf for gas, $1.00/bbl for oil and condensate, $1.00/bbl for water, and $.05/mcf per stage of compression, if available and a monthly contract operating fee of $10,000.00 for the first well and $5,000.00 for each additional well for a manned facility or $12,500.00 for the first well and $5,000.00 for each additional well for an unmanned facility (collectively "Fees"). In any month in which there is Farmout Production, if the Fees do not equal or exceed fifteen thousand dollars ($15,000.00) in any calendar month, then a minimum fee of fifteen thousand dollars ($15,000.00) shall be charged to Newfield in lieu of fees based upon throughput for such month, regardless of actual throughput. In any month in which there is no Farmout Production, the minimum monthly fee shall not exceed ten thousand dollars ($10,000.00). The Fees shall be adjusted on the first day of April of each year by multiplying the rate currently in use by the percentage increase in the average weekly earnings of Crude Petroleum and Gas Production Workers for the last calendar year compared to the calendar year preceding as shown published by the United States Department of Labor, Bureau of Labor Statistics. The increase in the Fees will be prorated to the date of initial Farmout Production during the first year of operation. Notwithstanding the above, in the event Apache determines in its sole judgment that it is uneconomic to continue to process Newfield's Farmout Production at Apache's production facilities, then Apache may discontinue the production handling services upon sixty (60) days written notice to Newfield and the parties will attempt to negotiate a sale or platform sublease agreement to all continued Farmout Production from wells drilled pursuant to this Agreement. The PHA shall provide that in the event such an agreement cannot be reached, then Apache shall designate Newfield as operator of the necessary Platform and facilities to enable Newfield to continue to process and handle its Farmout Production and in lieu of any fees under the PHA, Newfield shall bear and pay all actual LOE incurred in operating and maintaining the relevant Platform and facilities until Newfield's Farmout Production has depleted and Newfield has plugged and abandoned its wells at which time Apache shall be responsible for the plugging and abandonment of its wells and for the removal of its Platform. Newfield shall be responsible for all maintenance and repairs of the Platform, the facilities and its wells during Newfield's operation of the Platform and facilities. Newfield shall also be responsible for emergency and spill response as Newfield Exploration Company February 28, 2007 Page 7 of 20 required by regulatory authorities and shall be responsible for regulatory report while such Platform and facilities are operated by Newfield. NEWFIELD SHALL DEFEND, INDEMNIFY, RELEASE AND HOLD HARMLESS APACHE FROM AND AGAINST ANY SUCH DUTIES, RESPONSIBILITIES AND LIABILITIES. In the event installation of additional facilities for the separation, dehydration, compression, water disposal, measurement and sales ("Processing") of the Farmout Production or any modifications or upgrades to the Platform are necessary for the Processing of the Farmout Production, Newfield will incur all costs associated with such modifications and/or upgrades. In the event Apache's production of oil and gas from the Platform is interrupted for a period exceeding forty-eight (48) consecutive hours for each interruption as a result of Newfield's operations including but not limited to construction, installation, maintenance, well abandonment operations or removal of any facilities which belong to Newfield, then Newfield shall make a payment ("Downtime Fee") to Apache within thirty (30) days of receipt of a bill with supporting information from Apache. The Downtime Fee is to be calculated according to the number of hours of downtime per downtime event exceeding forty-eight (48) consecutive hours on the basis of Apache's average daily production for the previous forty-five (45) days and on the basis of the average published commodity price, for like kind and grade of product, which would have been received during such downtime period, as follows: (A x B) x (C) divided by (45 x 24) Where: A = number of hours of downtime after consecutive forty-eight (48) hour free period B = total daily production for previous forty-five (45) days C = Apache's average commodity sale price during downtime period V. INFORMATION REQUIREMENTS ------------------------ Newfield shall deliver to Apache, free of cost, the information set out in Exhibit "A", attached hereto, and all other geological and geophysical, engineering, technical, production test, exploratory, and reservoir information, and any logs or other information and data that Newfield might acquire from the Initial Test Well or any other well drilled by Newfield on the Contract Area but only to the extent that such information is not restricted by licensing agreements. Delivery of such information to Apache shall be a condition of Newfield earning the Assignment provided for in Section III. VI. CONFIDENTIALITY --------------- A. The term "Confidential Information" shall include any geological, geophysical, engineering, technical, production test, exploratory, or reservoir information, or any logs or other information delivered to Newfield Exploration Company February 28, 2007 Page 8 of 20 Apache by Newfield pursuant to Section V above.

Each Party shall use at least the same degree of care in protecting the Confidential Information as it uses in protecting its own proprietary materials. B. Apache shall not have any obligation to limit disclosure or use of any portion of Confidential Information which: 1. Is already in Apache's possession prior to receipt hereunder; 2. Is now in or hereafter becomes publicly available through no fault of Apache; 3. Is disclosed to Apache without obligation of confidence by a third party which has the right to make such disclosure; or 4. Is independently developed by or for Apache without reference to Confidential Information received under this Agreement. C. Any Party may make Confidential Information available to third parties without the consent of the other Party as follows: 1. To a consultant or engineering firm for hydrocarbon reserve or other technical evaluation, analysis or interpretation or for reprocessing, provided that such consultant or engineering firm is not allowed to retain a copy of the Confidential Information after completion of its services and agrees in writing to treat it as confidential. 2. To show, but not provide copies, to a third party with which a Party is negotiating sale of all or part of its interest in the Contract Area, or a possible merger or consolidation or sale of its business operations; provided that such third party or parties agree in writing, to hold all such Confidential Information in confidence. In the event of completion of a transaction contemplated by this Section VI.C.2., a copy of all Confidential Information may be provided to the successor in interest of such Party and such Party may also retain copies of the Confidential Information with all the rights and obligations which it had prior to the completion of the transaction. 3.

VII. CONSENT TO ASSIGN ----------------- Except for assignments to affiliates of Newfield, internal partners of Newfield or financial institutions as part of a financing arrangement, Newfield may not assign any rights Agreement without the prior written consent of Apache, and any assignment made without such consent shall be void. Such request shall contain the name, address and percentage of participation of the proposed assignee. Should Newfield request Apache's consent to assign to a willing and financially able party, Apache's consent shall not be unreasonably withheld. Notwithstanding Apache's consent to assign, Newfield shall remain fully liable to Apache for the performance of all obligations incurred prior to the effective date of the Assignment under this Agreement. All assignments shall be made expressly subject to this Agreement and Apache shall not be under any obligation to recognize any assignment of this Agreement pursuant to the terms hereof unless and until it has received from Newfield a true and correct copy of same and assignee has ratified this Agreement.
