If the parties are unable to reach agreement on such terms, the matter will be resolved in accordance with the dispute resolution procedures set forth in Exhibit “B” attached hereto

ARTICLE III - ALLOCATION

3.1 Available Gas and Gallons

(a) For each monthly period, Seller’s “available Gas” at each delivery point shall be determined on a component basis by multiplying the monthly delivered volume in MCF at such delivery point by the mole fraction of each component contained therein, as determined from the Gas sample analysis set forth in Article 8, SETTLEMENT TESTS, then deducting the component volume in MCF of unprocessed Gas used for fuel which is attributable to Seller’s available Gas, as determined in Article 3.4.

(b) For each monthly period, Seller’s “available gallons” of Product for each delivery point shall be determined on a component basis by dividing the available Gas for each component at each delivery point, as determined in Article 3.1(a) by the applicable Cubic Foot per Gallon physical constant as published in GPA publication 2145-94 or the most current revision. The physical constant for Normal Hexane shall be used for the Hexanes Plus Component.

3.2 Allocation of Products

(a) For each monthly period, the “actual net Plant production” of each Product in gallons shall be the total deliveries of that Product delivered from Buyer’s Plant.

(b) Seller’s allotment of the actual net Plant production of each Product shall be determined by multiplying Seller’s available gallons of such Product from all delivery points by a fraction, the numerator of which is the actual net Plant production of that Product and the denominator of which is the available gallons of such Product from all delivery points.

3.3 Allocation of Residue Gas

(a) For each monthly period, Seller’s allotment of the total Residue Gas sold from Buyer’s Plant, hereinafter referred to as Seller’s “allocated Residue”, shall be determined by multiplying each component of Seller’s available Gas as determined in Article 3.1(a) by a fraction, the numerator of which is the sum of each applicable component

(2) CONFIDENTIAL TREATMENT HAS BEEN REQUESTED BY RESACA EXPLOITATION, INC. FOR CERTAIN PORTIONS OF THIS DOCUMENT. CONFIDENTIAL PORTIONS HAVE BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. OMITTED PORTIONS ARE INDICATED IN THIS AGREEMENT WITH “*****”.

volume in MCF for Residue Gas sold, for Residue Gas used for fuel, and for Residue Gas returned to lease(s) from Buyer’s Plant and the denominator of which is each applicable component volume in MCF of the available Gas from all delivery points.

(b) Seller’s “allocated Residue Gas available for sale” shall be the sum of the following; each component of Seller’s allocated Residue as determined in Article 3.3(a) multiplied by the applicable Btu per Cubic Foot physical constant as published in GPA publication 2145-94 or the most current update, less Seller’s allocated fuel in MMBtu’s as determined in Article 3.4.

3.4 Allocation of Fuel

Buyer at its sole discretion shall have the right to utilize either processed or unprocessed Gas as fuel.

(a) The volume of processed Gas used as fuel, converted to MMBtu’s using the same conversion factors as in Paragraph 3.3(b), allocated to Seller’s available Gas shall be determined by multiplying the fuel volume in MMBtu by a fraction, the numerator of which is Seller’s available Gas utilizing the facilities utilizing processed Gas as fuel, the denominator of which is the available Gas from all delivery points utilizing the facilities utilizing processed Gas as fuel.

(b) The volume of unprocessed Gas used as fuel shall be determined by multiplying the component volume in MCF of the unprocessed Gas utilized as fuel by such facilities, by a fraction, the numerator of which is Seller’s available Gas or monthly delivered volume in MCF whichever is applicable, the denominator of which is the available Gas or monthly delivered volume in MCF from all delivery points utilizing the facilities utilizing unprocessed Gas as fuel.

(c) If Buyer utilizes Residue Gas or Gas furnished by a third party for fuel, such Gas value or volume shall be allocated as in Article 3.4(a) herein.

3.5 Allocation of Electrical Power

In the event Buyer elects to utilize electrical power in the operation of compressors at the processing Plant or located in the field, such electrical power costs will be allocated to Seller’s Gas by multiplying the total electrical power cost times a factor, the numerator of which is the volume of Gas delivered hereunder utilizing such compressors and the denominator of which is the total volume of Gas utilizing such compressors. Seller’s allocated electrical cost will then be subtracted from the net proceeds from the sale of Residue Gas attributable to the Gas delivered by Seller before dividing the Residue income between Buyer and Seller as provided in Article 2.2.

3.6 Allocation Change

Buyer, at its sole discretion may at any time and from time to time change the existing allocation procedure set forth herein, to accommodate changes in industry practices or standards.

ARTICLE IV - TERM

4.1 Effective Date

This Contract will become effective on the date first set forth above and will remain in full force and effect for the life of the Interests (or any extension or renewal thereto) described in Exhibit “A” hereto.

4.2 Termination

9.2 Standards

(a) All Gas volumes measured hereunder shall be computed to a standard pressure base of fourteen and sixty-five one-hundredths (14.65) pounds per square inch absolute at a standard base temperature of sixty degrees Fahrenheit (60ºF). For purposes of measurement computations the average atmospheric pressure shall be assumed to be thirteen and two-tenths (13.2) pounds per square inch and the average flowing temperature shall be assumed to be sixty degrees Fahrenheit (60ºF). All orifice coefficient computations shall be made in accordance with published procedures adopted as American National Standard, “Orifice Metering of Natural Gas, “published as ANSI/API 2530 as amended or revised from time to time, except that the Xxxxxxxx Number, Expansion, and Manometer Factors shall each be considered as unity, and only those Gas volumes measured at pressures of 100 pounds per square inch gauge or greater shall be corrected for deviation from Xxxxx’x Law.

(b) Notwithstanding the foregoing, at Buyer’s option the flowing temperature of the Gas may be determined by means of a recording thermometer installed by and at the expense of Buyer. In the event Buyer elects to exercise such option, the average recorded temperature of the Gas delivered during each month shall be deemed to be the temperature of such Gas so delivered during such month or if Buyer elects to use the capabilities of an electronic flow recorder then the flowing temperature shall be deemed to be the temperature of such Gas so delivered during such month.

9.3 Frequency of Calibration

Buyer shall test the meter installed at each delivery point semiannually

9.4 Accuracy

(a) Said meter, or meters, shall be open to inspection during Buyer’s normal working hours by Seller in the presence of Buyer. In case any question arises as to the accuracy of the meter measurement, said meter, or meters, shall be tested upon the demand of either party. The expense of such tests shall be borne by the party demanding same if the meter is found to be correct and by Buyer if found incorrect. A registration within 2% of correct shall be considered correct.

Seller may, at any time, without liability to Buyer clean out, deepen, or abandon any well or xxxxx on the above-described lands or may use any efficient, modern, or improved method for the production of oil. Before any well or xxxxx are taken out of service for any reason whatsoever, Seller agrees to first shut off the same from communication with Buyer’s Gathering System.

ARTICLE XVIII - SCOPE

18.1

In the event this Contract covers more than one lease or well, this Contract shall be construed as a separate contract as to each lease or well.

ARTICLE XIX - TAXES

19.1 Responsibility

Seller shall bear all taxes imposed upon Seller with respect to the Gas delivered hereunder prior to delivery to Buyer and any processing taxes imposed upon the processing of Seller’s Gas and Buyer shall bear all taxes imposed upon Buyer with respect to such Gas after delivery thereof to Buyer (except processing taxes). If required by law or requested by Seller, Buyer shall remit Seller’s taxes to the proper authority and deduct the amount so paid from Buyer’s payment to Seller.

ARTICLE XX - LAWS AND REGULATIONS

20.1

This Contract and all provisions herein shall be subject to and performed in accordance with all present and future, applicable and valid orders, laws, rules and regulations of any duly constituted federal, state or local governmental authority now or hereafter having jurisdiction over the parties, their facilities, the Gas delivered hereunder or this Contract. This Contract shall be governed by and interpreted in accordance with the laws of the State of Texas, notwithstanding any conflict of laws or rules which may require or permit the application of the laws of another jurisdiction.

ARTICLE XXI - PAYMENT

21.1 Time and Examination

Payment shall be mailed by Buyer not later than the last day of each month for all Gas purchased hereunder during the preceding month, and a statement showing full details of the account shall be transmitted to Seller. Examination by Seller of the accounting records kept by Buyer respecting said Gas account shall be permitted by Buyer at any and all reasonable business hours and to the extent necessary to verify the accuracy of any statement, charge, computation, or demand made under or pursuant to this Contract.

21.2 Claim Period

All statements and/or invoices rendered to Seller under the terms of this Contract during any calendar year shall be conclusively presumed to be true and correct after twenty-four (24) months following the end of any such calendar year unless Seller within such twenty-four month period makes a written claim on Buyer for adjustment. Failure to make a claim for adjustment within such period shall presumptively establish the correctness of such statements

and/or invoices and shall preclude the making of claims for adjustment thereon in any manner whatsoever, whether by filing an action in a court of law or otherwise. The making of a written claim for adjustment against Buyer by any method other than the initiation of the Alternative Dispute Resolution Procedures set forth in Exhibit “B” shall not operate to suspend the running of the applicable statute of limitations for such claim. This paragraph shall only operate to bar claims for adjustment made by Seller (or any agent of Seller) against Buyer; it shall not operate to bar claims for adjustment made by Buyer (or any agent of Buyer) against Seller.

21.3 Receiver of Statements

If the lease or well(s) described herein are owned by two or more parties, the Gas purchase statement will be sent to the Operator thereof and payment of any sums due Seller hereunder shall be made to the party designated as Operator of such lease or well(s) who shall make proper distribution to Seller, or at the written request of any working interest owner and subject to Article 11.2, Buyer may make payment of any sums due such working interest owner directly to such owner.

ARTICLE XXII - ASSIGNMENT

22.1 Conveyance

The provisions of this Contract shall be binding upon and inure to the benefit of the parties hereto, their heirs, successors and assigns. If Seller assigns or conveys all or any part of the leases or other properties covered hereby, Seller shall provide in any instrument of assignment or conveyance that the leases or other properties are assigned or conveyed subject to the terms and conditions of this Contract and that the party or parties to whom such assignment or conveyance is made shall be bound by the terms of this Contract.

22.2 Notification

Seller shall make a concerted effort to notify Buyer of any assignment of all or any portion of the leases or properties covered hereby.

Nothing else in this Contract to the contrary, Seller agrees that in the event it fails to comply with this paragraph, Buyer shall have the right, at its option, to refuse to accept delivery of Seller’s Gas during any period of such non-compliance.

ALTERNATIVE DISPUTE RESOLUTION PROCEDURES

1. Initiation of Procedures. Either party desiring to initiate the dispute resolution procedures set forth herein with respect to a Dispute not resolved in the ordinary course of business (the “initiating Party”) must give written notice of the Dispute (the “Dispute Notice”) to the other party (the “Non-initiating Party”). The Dispute Notice shall include (i) a statement of that party’s position and a summary of arguments supporting that position, and (ii) the name and title of the executive who will represent that party, and of any other person who will accompany the executive, in the negotiations under Article 2 below.

2. Negotiation Between Executives. If one party has given a Dispute Notice under Article l above, the Parties shall attempt in good faith to resolve the Dispute within forty-five (45) days following receipt of the Dispute Notice by the Non-Initiating Party by negotiation between executives who have authority to settle the Dispute and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement or the matter In Dispute. Within fifteen (15) days after receipt of the Dispute Notice, the Non-Initiating Party shall submit to the other a written response. The response will include (i) a statement of that party’s position and a summary of arguments supporting that position, and (ii) the name and title of the executive who will represent that party and of any other person who will accompany the executive. Within forty-five (45) days following receipt of the Dispute Notice by the Non-Initiating Party, the executives of both Parties will meet at a mutually acceptable time and place, and thereafter, as often as they reasonably deem necessary, to attempt to resolve the Dispute.

3. Mediation. If the Dispute has not been resolved by negotiation under the Article 2 above within forty-five (45) days following receipt of the Dispute Notice by the Non-Initiating Party or If the Non-Initiating Party fails to respond within the required fifteen (15) day period, either party may initiate the mediation procedure of this Article 3 by giving written notice to the other party (“Mediation Notice”). The Parties will endeavor to settle the Dispute by mediation within sixty (60) days of the Mediation Notice under the then current Center for Public Resources (“CPR”) Model Mediation Procedure for Business Disputes. If the Parties have not agreed upon a mediator within seven (7) days after the Mediation Notice, either party may request CPR assistance in the selection of a mediator under its guidelines. Unless otherwise agreed to by the Parties, no discovery shall be allowed during the sixty (60) day mediation period. The cost of the mediator will be shared equally between the Parties, unless otherwise agreed to in writing by the Parties.

4. Arbitration. If the Dispute has not been resolved by mediation under the Article 3 above within the required sixty (60) day period or if either party fails and/or refuses to participate in such mediation procedures, either party may request that the matter be resolved through arbitration by submitting a written notice (the “Arbitration Notice”) to the other. Any arbitration that is conducted hereunder shall be governed by the Federal Arbitration Act, 9 U.S.C § 1 et seq., as amended, and will not be governed by the arbitration acts, statutes, or rules of any other jurisdiction.

5. Arbitration Procedure. The Arbitration Notice shall name the noticing party’s arbitrator and shall contain a statement of the issue(s) presented for arbitration. Within fifteen (15) Days of receipt of an Arbitration Notice, the other party shall name its arbitrator by written notice to the other and may designate any additional issue(s) for arbitration. The two named arbitrators shall select the third arbitrator within fifteen (15) Days after the date on which the second arbitrator was named. Should the two arbitrators fail to agree on the selection of the third arbitrator, either party shall be entitled to request the Senior Judge of the United States District Court for the Southern District of Texas to select the third arbitrator. Should either party fail and/or refuse to name its arbitrator within the required fifteen (15) day period, the other party shall be entitled to request the Senior Judge of the United States District Court for the Southern District of Texas to select the arbitrator for such party. All arbitrators shall be qualified by education or experience within the natural gas liquids portion of the energy industry to decide the issues presented for arbitration. No arbitrator shall be: a current or former director, officer, or employee of either party or its Affiliates; an attorney (or member of a law firm) who has rendered legal services to either party or its Affiliates within the preceding three Years; or an owner of significant shares (more than 2%) of the common stock of either party, or its Affiliates.

6. Arbitration Hearing. The three arbitrators shall commence the arbitration proceedings within twenty-five (25) Days following the appointment of the third arbitrator. The arbitration proceedings shall be held at a mutually acceptable site and if the Parties are unable to agree on a site, the arbitrators shall select the site. The arbitrators shall have the authority to establish rules and procedures governing the arbitration proceedings, including, without limitation, rules concerning discovery. Each party shall have the opportunity to present its evidence at the hearing. The arbitrators may call for the submission of pre-hearing statements of position and legal authority, but no post-hearing briefs shall be submitted. The arbitration panel shall not have the authority to award incidental, consequential, special, punitive or exemplary damages. In addition, if an issue under consideration is limited to a determination of an amount of money owed by one party to the other, each party shall submit to the arbitration panel a final offer of its proposed resolution of the Dispute. The arbitration panel shall be charged to select from the two proposals the one which the panel finds to be the most reasonable and consistent with the terms and conditions of this Agreement, and the arbitration panel shall not average the Parties’ proposals or otherwise craft its own remedy. All evidence submitted in an arbitration proceeding, transcripts of such proceedings, and all documents submitted by the Parties in an arbitration proceeding shall be kept confidential and shall not be disclosed to any third party by either party hereto.

7. Arbitration Decision and Costs. The decision of the arbitrators or a majority of them, shall be in writing and shall be final and binding upon the Parties as to the issue(s) submitted. The cost of the hearing shall be shared equally by the Parties, and each party shall be responsible for its own expenses and those of its counsel or other representatives. Each party hereby irrevocably waives, to the fullest extent permitted by law, any objection it may have to the arbitrability of any such Disputes and further agrees that a final determination in any such arbitration proceeding shall be conclusive and binding upon each party.

8. Enforcement of Award. Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. The prevailing party shall be entitled to reasonable attorneys’ fees in any contested court proceeding brought to enforce or collect any award of judgment rendered by the arbitrators.

9. Tolling and Performance. Except as otherwise provided in these procedures, all applicable statutes of limitation and defenses based upon the passage of time and all contractual limitation periods specified in this Agreement, if any, will be tolled while the procedures specified herein are pending. The Parties will take all actions necessary to effectuate the tolling of any applicable statute of limitation or contractual limitation periods. All deadlines specified herein may be extended by mutual written agreement of the Parties. Each party is required to continue to perform its obligations under this Agreement pending final resolution of any Dispute, unless to do so would be impossible or impracticable under the circumstances. Notwithstanding the foregoing, the statute of limitations of the State of Texas applicable to the commencement of a lawsuit will apply to the commencement of an arbitration under this Agreement, except that no defenses will be available based upon the passage of time during any negotiation or mediation called for by these procedures.

Attn: Contract Administration

RE:	GAS DELIVERED AND SOLD BY COMPANY TO VERSADO GAS PROCESSORS, L.L.C. (“VERSADO”) AT VERSADO’S XXXXXX PLANT (“PLANT”) LOCATED IN LEA COUNTY, NEW MEXICO.

Gentlemen:

Versado is currently gathering and processing gas (“Gas”) from Company pursuant to purchase and/or processing contract(s) and/or agreement(s) (collectively, and as amended, the “Contract(s)”). The Gas is processed under the terms of the Contract(s) at the Plant. The residue gas remaining after processing (“Residue”) is delivered to El Paso Natural Gas Company (“EPNG”).

EPNG has notified Versado that it currently contemplates that effective November 1, 2008 and extending through December 31, 2008 (“Curtailment Period”) EPNG will severely curtail its receipt of Residue from the Plant and will only accept 30MMscf/d of Residue (“Base Residue”) from the Plant. This curtailment is being done in order to facilitate modifications to be made by EPNG to EPNG’s system. Notwithstanding the foregoing, for purposes of this letter agreement the Curtailment Period will be deemed to commence on November 1, 2008 and continue through the later of the date that EPNG ceases the referenced curtailment, or December 31, 2008.

Versado is evaluating a project to install pipeline and appurtenant facilities and set rental compression (collectively, the “Project”) at or near the Plant which will, in our judgment, allow Versado to deliver into EPNG some or all of any Residue exceeding the Base Residue and available at the tailgate of the Plant “(Excess Residue”). The Project will

require a substantial investment in compression, pipelines and necessary appurtenances for the Plant. Versado believes it is in the best interest of all the producers, including Company, delivering Gas into Versado’s systems that feed Gas into the Plant (collectively, “Producers”), to participate in the Project, rather than curtailing their Gas deliveries to Versado in order to meet EPNG’s directives. The actual cost of the Project’s installation and construction is estimated to be $290,000 and the Project’s actual rental costs for the compression equipment are estimated to be $407,400 for the two months.

Versado, subject to the provisions hereof, is prepared to move forward with the installation, construction and subsequent operation of the Project. Versado would propose that, in return therefore, it receive from Company a fee (“Excess Residue Handling Fee”), computed and paid, or deducted from any proceeds otherwise due Company from the Contract(s), on a monthly basis relevant to Gas delivered during the Curtailment Period, equal to the following:

1. Company’s pro-rata share [“Pro-Rata Share”] (determined by the percentage Company’s wellhead thousand standard cubic feet per month (“WH mscf/m”) gas delivered to Versado’s Plant bears to all wellhead WH mscf/m gas delivered to Versado’s Plant times eighty-five percent) of installation and constructions costs relevant to the Project, and

2. Company’s Pro-Rata Share of compression rental costs.

The Excess Residue Handling Fee would be chargeable on all Gas delivered during the Curtailment Period.

Versado’s obligation to proceed with the Project shall be subject to Versado’s determination, in the exercise of reasonable commercial judgment, that Producers (together controlling a quantity of Gas adequate to make the Project financially justifiable) have entered in agreements with Versado similar in substance to this letter agreement.

This letter agreement shall constitute an amendment to each of the Contract(s). In the event of any conflict between the terms contained in this letter agreement and those contained in any of the Contract(s) as previously written, the terms contained in this letter agreement shall control.

If the foregoing is acceptable to Company, please execute both originals hereof in the space provided. Please return one fully executed original to Targa by no later than October 15, 2008 and retain one for your records.

	Sincerely,


	/s/ Xxxxx Xxxxx
