The properties, rights and interests specified in the foregoing subsections (a), (b) and (c), except for the Excluded Properties, as defined below, are herein sometimes collectively called the “Oil and Gas Properties,” and individually an “Oil and Gas Property,” and the properties, rights and interests specified in the foregoing subsections (a), (b), (c), (d) and (e), except for the Excluded Properties, are herein sometimes collectively called the “Properties” and individually a “Property”.

Section 2.2. Excluded Properties. The Properties do not include, and there is hereby expressly excepted and excluded therefrom and reserved to Seller:

(a) all rights and chooses in action, arising, occurring or existing in favor of Seller prior to the Effective Date or arising out of the operation of or production from the Oil and Gas Properties prior to the Effective Date (including, but not limited to, any and all contract rights, claims, receivables, revenues, recoupment rights, recovery rights, accounting adjustments, mispayments, erroneous payments or other claims of any nature in favor of Seller and relating and accruing to any time period prior to the Effective Date);

(b) all corporate, financial, tax and legal (other than title) records of Seller;

(d) all hydrocarbon production from or attributable to the Properties with respect to all periods prior to the Effective Date, as described in Section 11.1 and all proceeds attributable thereto;

(e) any refund of costs, taxes or expenses borne by Seller attributable to the period prior to the Effective Date;

(f) Properties excluded from the purchase and sale contemplated by this Agreement under Section 7.5(b);

(g) any other right or interest in and to the Properties to the extent attributable to the period prior to the Effective Date;

(h) copies (but not the originals) of all files (described in Section 10.1);

(i) all deposits, cash, checks, funds and accounts receivable attributable to Seller’s interests in the Properties with respect to any period of time prior to the Effective Date;

(j) all computer or communications software or intellectual property (including tapes, data and program documentation and all tangible manifestations and technical information relating thereto) owned, licensed or used by Seller in its central office, except all such property owned or licensed by Seller and used in the field and all data owned or licensed by Seller and used in connection with the exploration, development, operation or maintenance of the Properties or to prepare the information provided in the virtual data room on the website of Waterous; provided, however, to the extent that Seller is prevented from disclosing or transferring any such property to Buyer, due to obligations to third parties, such property shall be excluded from the Properties and Seller shall provide Buyer with a written notice describing all such property prior to Close;

(k) any vehicles, logo, service ▇▇▇▇, copyright, trade name or trademark of or associated with Seller or any affiliate of Seller or any business of Seller or of any affiliate of Seller; and

(l) any programs, software, property, records, files, information, or data, created or owned by any limited partner of any Seller even if such property has been furnished to Seller.

(m) Any documents withheld or not transferred pursuant to Section 10.1.

These excluded properties, rights and interests specified in the foregoing subsections (a) through (l), inclusive, of this Section 2.2 are collectively referred to as the “Excluded Properties.” Buyer shall not be responsible for, and Seller expressly retains, all liabilities related to the Excluded Properties, whether such liabilities arise before or after the Effective Date. It is understood that certain of the Excluded Properties may not be embraced by the term Properties. The fact that certain properties, rights and interests have been expressly excluded is not intended to suggest that had they not been excluded they would have constituted Properties and shall not be used to interpret the meaning of any word or phrase used in describing the Properties.

ARTICLE III.
Purchase Price

Section 3.1. Purchase Price. The purchase price for the Properties shall be $345,000,000.00 (such amount, unadjusted by any adjustments provided for in this Agreement or agreed to by the parties, being herein called the “Base Purchase Price”). Such Base Purchase Price may be adjusted as provided in Section 6.5 and Article VII hereof (the Base Purchase Price, as so adjusted, and as the same may otherwise be adjusted by mutual agreement of the parties, being herein called the “Purchase Price”). The Purchase Price shall be paid in cash at the Closing as hereinafter provided. Any net amounts paid to or received by Buyer under Sections 11.2, 11.3 or 11.4 for the period beginning on the Effective Date and ending on the Closing Date shall be treated as a reduction in the Purchase Price, and any net amounts paid to or retained by Seller under Sections 11.2, 11.3 or 11.4 for the period beginning on the Effective Date and ending on the Closing Date shall be treated as an increase in the Purchase Price.

Section 3.2. Deposit. Contemporaneously with the execution of this Agreement, Buyer has paid to Seller an amount equal to 5% of the Base Purchase Price (such amount being herein called the “Deposit”). In the event the transaction contemplated hereby is consummated in accordance with the terms hereof, the Deposit shall be applied to the Purchase Price to be paid by Buyer at the Closing. In the event this Agreement is terminated by Buyer or Seller in accordance with Section 8.1 or 8.2 below, the Deposit shall be returned to Buyer or retained by Seller as provided in such Sections. The Deposit shall bear interest at the rate paid by the banking institution at which Seller deposits the Deposit, and if the same is paid to Buyer, or if Buyer receives credit for same against the Purchase Price paid at Closing, such payment, or credit, shall be in the amount of the Deposit plus the amount of such interest. THE PARTIES HEREBY ACKNOWLEDGE THAT THE EXTENT OF DAMAGES TO SELLER OCCASIONED BY THE FAILURE OF THIS TRANSACTION TO BE CONSUMMATED WOULD BE IMPOSSIBLE OR EXTREMELY DIFFICULT TO ASCERTAIN AND THAT THE AMOUNT OF THE DEPOSIT IS A FAIR AND REASONABLE ESTIMATE OF SUCH DAMAGES UNDER THE CIRCUMSTANCES AND DOES NOT CONSTITUTE A PENALTY.

ARTICLE IV.
Representations of Seller

Section 4.1. Representations of Seller. Seller represents to Buyer that as of the date of this Agreement:

To Seller’s Knowledge, Seller is not in material breach of the oil, gas and/or mineral leases, or any material contracts and agreements comprising any part of the Properties (such leases, material contracts, and agreements being herein called the “Basic Documents”) and to Seller’s Knowledge all Basic Documents are set forth on Exhibits A and A-1. All royalties, overriding royalties and other similar payments due and payable on production with respect to any lease have been timely and properly paid, except (i) amounts that are being held in suspense which will not result in grounds for cancellation of Seller’s rights in such lease and (ii) matters which are not reasonably likely to have a material adverse effect on the Properties, taken as a whole.

(g) Commitments, Abandonments or Proposals. Except as set forth in Exhibit 4.1(g), to Seller’s Knowledge; (a) Seller has incurred no expenses, and has made no commitments to make expenditures (including Seller has not entered into any agreements that would obligate Buyer to make expenditures), in connection with the ownership or operation of the Properties after the Effective Date, other than routine expenses incurred in the normal operation of existing ▇▇▇▇▇ on the Oil and Gas Properties; (b) Seller has not abandoned any ▇▇▇▇▇ (or removed any material items of equipment, except those replaced by items of materially equal suitability) on the Oil and Gas Properties since the Effective Date; and (c) no proposals or authorities for expenditures are currently outstanding (whether made by Seller or by any other party) to drill additional ▇▇▇▇▇, or to deepen, plug back, or rework existing ▇▇▇▇▇, or to conduct other operations for which consent is required under the applicable operating or unitization agreement, or to conduct any other operations other than normal operation of existing ▇▇▇▇▇ on the Oil and Gas Properties, or to abandon any ▇▇▇▇▇, on the Oil and Gas Properties.

(l) Production. Except as described in Exhibit 4.1(l) to this Agreement, Seller is not obligated to deliver oil, gas or other minerals produced from the Properties at some future time without then or thereafter receiving payment for the production at less than the prevailing market price.

BUYER IS RELYING SOLELY UPON ITS OWN INSPECTION OF THE PROPERTIES, AND BUYER SHALL ACCEPT ALL OF THE SAME IN THEIR “AS IS”, “WHERE IS” CONDITION.

Section 4.3. Disclosures. The matters set forth on any of the exhibits referred to in Section 4.1 are not necessarily matters that Seller is required to disclose or matters that would constitute a breach of any representation or warranty had such matters not been disclosed.

Seller shall provide Buyer with a description of all such prohibited or privileged data within one week after execution of this Agreement.

BUYER RECOGNIZES AND AGREES THAT ALL MATERIALS, DOCUMENTS, AND OTHER INFORMATION, MADE AVAILABLE TO IT IN CONNECTION WITH THE TRANSACTION CONTEMPLATED HEREBY, WHETHER MADE AVAILABLE PURSUANT TO THIS SECTION OR OTHERWISE, ARE MADE AVAILABLE TO IT AS AN ACCOMMODATION, AND WITHOUT REPRESENTATION OR WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, AS TO THE ACCURACY AND COMPLETENESS OF SUCH MATERIALS, DOCUMENTS, AND OTHER INFORMATION.

THE FOREGOING RELEASE AND INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH CLAIMS, ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY.

Section 6.4. Interim Operation. Seller will continue the operation of the Properties in the ordinary course of its business (or, where Seller is not the operator of a Property, will continue its actions as a non-operator in the ordinary course of its business), and will not sell or otherwise dispose of any portion of the Oil and Gas Properties, except for sales or other dispositions of (i) oil, gas and other minerals in the ordinary course of business after production, or (ii) equipment and other personal property or fixtures in the ordinary course of business where the same has become obsolete, is otherwise no longer necessary for the operation of the Properties, or is replaced by an item or items of at least equal suitability. Should Seller receive (or desire to make) any proposals to drill additional ▇▇▇▇▇ on the Oil and Gas Properties, or to conduct other operations which require consent of nonoperators under the applicable operating agreement, it will notify Buyer of, and consult with Buyer concerning, such proposals, but any decisions with respect to proposals shall be made by Seller in its sole discretion, so long as the decisions are made in the ordinary course of business. Without expanding any obligations which Seller may have to Buyer, it is expressly agreed that Seller shall never have any liability to Buyer with respect to operation of a Property greater than that which it might have as the operator to a non-operator under the applicable operating agreement (or, in the absence of such an agreement, under the AAPL 610 (1989 Revision) form Operating Agreement), IT BEING RECOGNIZED THAT, UNDER SUCH AGREEMENTS AND SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE FOR ITS OWN NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER THAN FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

Section 6.5. Preferential Rights and Consents. Seller will use reasonable efforts, consistent with industry practices in transactions of this type, to identify, with respect to all material Oil and Gas Properties, (i) all preferential rights to purchase (“Preferential Rights”) and requirements that consents to assignment (“Consents”) be obtained which would be applicable to the transactions contemplated hereby and (ii) the names and addresses of parties holding such rights; in attempting to identify such Preferential Rights and Consents, and the names and addresses of such parties holding the same, Seller shall in no event be obligated to go beyond its own records. Seller will request, from the parties so identified (and in accordance with the documents creating such rights), execution of Consents and/or waivers of Preferential Rights so identified. Seller shall have no obligation other than to so attempt to identify such Preferential Rights or Consents and to so request such execution of Consents and/or waivers of Preferential Rights (including, without limitation, Seller shall have no obligation to Buyer to assure that such Consents or waivers of Preferential Rights are obtained). Buyer has allocated an amount of the Base Purchase Price to each Property as shown on Schedule I. If a party from whom a waiver of a Preferential Right is requested refuses to give such waiver, and the period of time to exercise such Preferential Right has not expired, such Preferential Right shall not constitute a Defect, but Seller may elect to exclude the Property affected by such Preferential Right and to reduce the Base Purchase Price by an amount calculated in the manner provided in Section 7.5 (b). Upon the exercise of any Preferential Rights after the Closing with respect to any Property conveyed to Buyer, Buyer will tender the required interest in such Property affected by such unwaived Preferential Right, at the allocated portion (“Allocated Amount”) of the Base Purchase Price set forth on Schedule I for such affected Property (or portion thereof) to the holder, or holders, of such right. In return for tendering the Property to such holder(s), Buyer shall collect and retain such amount from such purchaser.

ARTICLE VII.
Due Diligence Review

Section 7.1. Review By Buyer. Should, as a result of Buyer’s examinations and investigations, or otherwise, one or more matters come to Buyer’s attention which would constitute a Defect (as below defined), and should there be one or more of such Defects which Buyer is unwilling to waive and close the transaction contemplated hereby notwithstanding the fact that such Defects exist, Buyer shall notify Seller in writing of such Defects (such Defects of which Buyer so provides notice are herein called “Asserted Defects”) as soon as the same are identified by Buyer, but in no event later than September 20, 2004 (“Defect Deadline”). Such notification shall include, for each Asserted Defect, (i) a description of the Asserted Defect and the ▇▇▇▇▇ and/or units listed on Schedule I to which it relates and all supporting documentation reasonably necessary to fully describe the basis for the Defect or, if the supporting documentation is contained in Seller’s files, sufficient information to enable Seller to expeditiously locate such supporting documentation, (ii) for each applicable well or unit, the size of any variance from “Net Revenue Interest” or “Working Interest” which does or could result from such Asserted Defect and (iii) the amount by which Buyer would propose to adjust the Base Purchase Price. Any Defect with respect to which Buyer fails to so give Seller notice will be deemed waived for all purposes, including if applicable as a condition to Close. Buyer’s sole and exclusive rights and remedies with respect to any matter that constitutes a Defect shall be those set forth in this Article VII and Buyer shall not be shall not be entitled to indemnification or any other remedy with respect to any Defect. All access to Seller’s records and the Properties in connection with such due diligence shall be subject and pursuant to Section 6.1 (including, without limitation, the exculpation and indemnification provisions contained in Section 6.3).

Section 7.2. Nature of Defects . The term “Defect” as used in this Section shall mean the following:

(a) NRI or WI Variances. Seller’s ownership of the Properties is such that, with respect to a well or unit listed on Schedule I hereto, it (i) entitles Seller to receive a decimal share of the oil, gas and other hydrocarbons produced from such unit, or from currently producing completions in such well which is less than the decimal share set forth on Schedule I in connection with such well or unit in the column headed “Net Revenue Interest” or (ii) causes Seller to be obligated to bear a decimal share of the cost of operation of the currently producing completions in such well or unit greater than the decimal share set forth on Schedule I in connection with such well or unit in the column headed “Working Interest” (without at least a proportionate increase in the share of production to which Seller is entitled to receive from such well or unit).

(b) Liens. Seller’s ownership of an Oil and Gas Property is subject to a lien other than (i) a lien for taxes which is not yet delinquent or (ii) a mechanic’s or materialmen’s lien (or other similar lien), or a lien under an operating agreement or similar agreement, to the extent the same relates to expenses incurred in the normal course of business which are not yet delinquent or (iii) liens which will be released at or before Closing (the liens described in (i), (ii) and (iii) of this Section 7.2(b) are herein called “Excluded Liens”).

(c) Consents. Seller’s ownership of an Oil and Gas Property is subject to a requirement that Consent be obtained and any assignment without such Consent either is void or could reasonably be expected to terminate or result in forfeiture of Seller’s interest in the Property unless such Consent or a waiver of such Consent is obtained with respect to the transaction contemplated hereby.

(d) Imperfections in Title. Seller’s ownership of a Property which is real property is subject to an imperfection in title which, if asserted, would cause a Defect, as defined in Section 7.2 (a) above, to exist, and such imperfection in title is not such as would normally be waived by persons engaged in the oil and gas business when purchasing producing properties.

(e) Environmental Matters. Except as disclosed on Exhibit 7.2(e), the operations on any Property which is real property is in violation of Applicable Environmental Laws (below defined) in any material respect (“Applicable Environmental Laws” shall mean all federal, state or local laws, rules, orders or regulations pertaining to health or the environment, including those relating to waste materials and/or hazardous substances).

Section 7.3. Permitted Matters and Encumbrances. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall not constitute a Defect, a breach of any covenant, representation or warranty of Buyer or a failure to satisfy a condition to Buyer’s obligation to Close and shall not be asserted as such: defects or irregularities arising out of lack of corporate authorization or a variation in corporate name, unless Buyer provides affirmative evidence that such corporate action was not authorized and results in another person’s superior claim of title to the relevant Property; defects or irregularities that have been cured or remedied by applicable statutes of limitation or statutes for prescription; defects or irregularities in the chain of title consisting of the failure to recite marital status in documents or omissions of heirship proceedings; defects or irregularities in title which for a period of 5 years or more has not delayed or prevented Seller (or Seller’s predecessor, if owned by Seller less than 5 years) from receiving its Net Revenue Interest share of the proceeds of production or causes it to bear a share of expenses and costs greater than its Working Interest share from any unit or well; defects or irregularities resulting from or related to probate proceedings or the lack thereof which defects or irregularities have been outstanding for 2 years or more; a gas imbalance (e.g., a situation where Seller and its predecessor in title to the Properties have taken more or less gas from a well or unit than ownership of the Properties would entitle them to receive); conventional rights of reassignment normally actuated by an intent to abandon or release a lease and requiring notice to the holders of such rights and any other defect or irregularity as would normally be waived by persons engaged in the oil and gas business when purchasing producing properties.

Section 7.4. Seller's Response to Asserted Defects. In the event that Buyer notifies Seller of Asserted Defects:

(a) Cure. Seller may (but shall have no obligation to) attempt to cure, prior to Closing, one of more Asserted Defects.

(b) Adjustment. Notwithstanding any election made under Section 7.4(a), Seller may also elect to have one or more Asserted Defects, of the type not specified in Section 7.6, handled under Section 7.5 below.

Section 7.5. Resolution of Uncured Defects. In the event that, as a part of the due diligence reviews provided for in Section 7.1 above, Asserted Defects, that are not of the type specified in Section 7.6, are presented to Seller and Seller is unable or unwilling to cure such Asserted Defects prior to Closing, or in the event that Buyer or Seller has elected (pursuant to Section 13.1) to treat an Oil and Gas Property affected by a casualty loss as if it was an Oil and Gas Property affected by an Asserted Defect, then:

(a) Agree Upon Adjustment. Buyer and Seller shall, with respect to each Property affected by such matters, attempt to agree upon an appropriate downward adjustment of the Base Purchase Price to account for such matters; and

(b) Excluded Property. With respect to each Property as to which Buyer and Seller are unable to agree upon appropriate adjustment with respect to all such matters affecting such Property, such Property will be excluded from the transaction contemplated hereby, and the Base Purchase Price will be reduced by the “Allocated Amount” attributed on Schedule I to the ▇▇▇▇▇ located on such Property plus the “Allocated Amount” attributed on Schedule I to the units in which such Property participates (but in the case of such units, limited to the portion of such “Allocated Amount” which is proportionate to the portion of Seller’s interest in such units, respectively, which is attributable to such Property).

Section 7.6. Adjustment For Certain Uncured Defects. In the event that Buyer raises as an Asserted Defect one of the following types of Defects, the Purchase Price shall be adjusted as set forth below:

(a) NRI Variance/Proportionate Price Reductions. If the Asserted Defect is a Defect described in clause (i) of Section 7.2(a): a downward adjustment equal to the amount determined by multiplying the “Allocated Amount” set forth for such well or unit on Schedule I by a fraction (A) the numerator of which is an amount equal to the “Net Revenue Interest” shown on Schedule I for such well or unit less the decimal share to which Seller would be entitled to as a result of its ownership interest in such well or unit which is unaffected by such Defect and (B) the denominator of which is the “Net Revenue Interest” shown for such well or unit on Schedule I. Notwithstanding subsection (b) below, a Defect to which such subsection is applicable may, at Seller’s election, be treated as a Defect under this subsection.

(b) Liens/Payoff Amount. If the Asserted Defect is a Defect described in Section 7.2(b): a downward adjustment equal to the amount of the debt secured by such lien.

Section 7.7. Possible Upward Adjustments. Should Seller determine (or should Buyer, in the course of its due diligence reviews contemplated by Section 7.1 above, determine) that the ownership of the Properties by Seller entitles Seller to a decimal share of the production from a well or unit listed on Schedule I greater than the decimal share shown for such well or unit under the column headed “Net Revenue Interest” on such Schedule I, then such party shall propose an upward adjustment to the Base Purchase Price to account for such fact, in which case such adjustment shall be handled in the same manner as provided in Section 7.5 above with respect to adjustments for Asserted Defects. The party making such determination shall notify the other party no later than September 20, 2004.

Section 7.8. Limitations on Adjustments. If the Base Purchase Price reduction with respect to a particular Asserted Defect which would result from the above provided for procedure does not exceed $20,000.00 no adjustment shall be made for such Asserted Defect. If the Base Purchase Price reduction (or increase), which would result from the above provided for procedure, as applied to Defects set forth in Section 7.2(a) through (d) for which an adjustment is to be made (and to all upward adjustments under Section 7.7) does not exceed $7,500,000 (“Title Deductible”) as to such Defects and as applied to the Defects set forth in Section 7.2(e)for which adjustments are to be made does not exceed $7,500,000 (“Environmental Deductible”) as to such Defects, then no adjustment of the Base Purchase Price shall occur, and none of the Properties which would be excluded by such procedure shall be excluded. If the Base Purchase Price reduction (or increase) which would result from the above provided for procedure as applied to all Asserted Defects for which an adjustment is to be made (and to all upward adjustments under Section 7.7 exceeds, respectively, the Title Deductible or the Environmental Deductible, the Base Purchase Price shall be adjusted by the amount by which such reduction (or increase) exceeds the Environmental Deductible or Title Deductible, respectively.

(c) Buyer will bear all drilling costs, reworking costs, and all other capital expenditures which are incurred in connection with the development, exploration or operation of the Properties after the earlier of the Effective Date or the date of this Agreement.

It is agreed that, in making such adjustments:

(i) oil which was produced from the Oil and Gas Properties and which was, on the Effective Date, stored in tanks located on the Oil and Gas Properties (or located elsewhere but used by Seller to store oil produced from, or attributable to, the Oil and Gas Properties prior to delivery to oil purchasers) and above pipeline connections shall be deemed to have been produced before the Effective Date,

(ii) ad valorem and similar taxes assessed for periods prior to the Effective Date shall be borne by Seller and ad valorem taxes assessed for periods on or after the Effective Date shall be borne by Buyer (ad valorem and similar taxes shall be considered assessed for the period for which they are stated to be assessed, even if the same are based on production or other activities occurring in prior periods),

(iii) ad valorem and similar taxes assessed with respect to a period which the Effective Date splits shall be prorated based on the number of days in such period which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period after the Effective Date),

(iv) the provisions of Section 15.3 shall be given effect as if the same had taken effect on the Effective Date,

(v) casualty losses shall be handled in accordance with Section 3.1,

(vi) delay rentals, salt water disposal payments, surface use payments and right-of-way rentals shall be attributable to the period for which they are paid and prorated based upon the Effective Date, and

(vii) no consideration shall be given to the local, state or federal income tax liabilities of any party.

Section 11.2. Initial Adjustment at Closing. At least 5 days before the Closing Date, Seller shall provide to Buyer a statement showing its computations of the amount of the adjustments provided for in Section 11.1 above based on amounts which prior to such time have actually been paid or received by Seller. Buyer and Seller shall attempt to agree upon such adjustments prior to Closing, provided that if agreement is not reached, Seller’s computation shall be used at Closing, subject to further adjustment under Section 11.3 below. If the amount of adjustments so determined which would result in a credit to Buyer exceed the amount of adjustments so determined which would result in a credit to Seller, Buyer shall, as provided in Section 9.3 above, receive a credit at Closing for the amount of such excess, and if the converse is true, then, as provided in Section 9.3 above, the amount to be paid by Buyer to Seller at Closing shall be increased by the amount of such excess.

Section 11.3. Adjustment Post Closing. On or before 90 days after Closing, Buyer and Seller shall review any additional information which may then be available pertaining to the adjustments provided for in Section 11.1 above, shall determine if any additional adjustments should be made beyond those made at Closing (whether the same be made to account for expenses or revenues not considered in making the adjustments made at Closing, or to correct errors made in the adjustments made at Closing), and shall make any such adjustments by appropriate payments from Seller to Buyer or from Buyer to Seller. During the period between Closing and the point in time when such post closing adjustment has been agreed to, each party shall, on a monthly basis, pay over to the other any revenue received by it with respect to the Properties which was, under Section 11.1 above, allocated to such party; such payments shall be considered in making such post closing adjustment.

Section 11.4. Additional Adjustments. Should any additional adjustments provided for in Section 11.1 be required after such adjustments under Section 11.3are concluded, such adjustments shall be made by appropriate payments from Buyer to Seller or from Seller to Buyer.

Section 11.5. Imbalance Adjustments. At Closing, Buyer and Seller shall, based upon data available at that time, determine (i) the total amount of “overproduction” of gas as of the Effective Date with respect to the ▇▇▇▇▇ and units listed on Schedule I (e.g. volumes of gas, measured in Mcf, taken from such ▇▇▇▇▇ and units by the Seller and its predecessors in title to the Properties in excess of those volumes which the ownership of the Properties would entitle them to receive) and (ii) total amount of “underproduction” of gas as of the Effective Date with respect to ▇▇▇▇▇ and units listed in Schedule I (e.g. the amount by which the volumes of gas, measured in Mcf, from such ▇▇▇▇▇ and units which the ownership of the Properties by Seller and its predecessors in title thereto would entitle them to take exceeds the volumes taken from such ▇▇▇▇▇ and units by Seller and such predecessors). If the total amount of overproduction (as so determined) exceeds the total amount of underproduction (as so determined) Buyer shall, as provided in Section 9.3 above, receive a credit against the Purchase Price equal to $3 per Mcf times such excess. If the total amount of underproduction (as so determined) exceeds the total amount of overproduction (as so determined), then, as provided in Section 9.3 above, the amount to be paid by Buyer to Seller at Closing shall be increased by an amount equal to $3 per Mcf times such excess. There shall be no adjustment for overproduction or underproduction if the net amount does not exceed a value of $25,000 based upon the $3 per Mcf valuation.

ARTICLE XII.
Assumption and Indemnification

Section 12.1. Assumption and Indemnification By Buyer. From and after the Closing, Buyer shall assume, indemnify and hold Seller (and its partners, members, and all their affiliates, and all their respective directors, officers and employees ) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and consultants’ and attorneys’fees) of any kind or character (individually a “Seller’s Indemnified Loss” and collectively “Seller’s Indemnified Losses”) arising out of

(a) any misrepresentation or breach of any warranty, covenant or agreement of Buyer contained in this Agreement, or any certificate delivered at the Closing,

(b) the ownership and/or operation of the Properties regardless of whether the same accrued or otherwise arose before or after the Closing (including, without limitation, those arising under the contracts and agreements described in Section 2.1(d) above), provided that Buyer is not obligated to indemnify Seller under this subparagraph (b) for any Buyer’s Indemnified Loss to the extent that Seller is obligated to indemnify Buyer for such Buyer’s Indemnified Loss pursuant to this Agreement,

(c) the condition (“Condition of the Properties”) of the Properties on the date of Closing (including, without limitation, within such matters all obligations to properly plug and abandon, or replug and re-abandon, ▇▇▇▇▇ located on the Properties, to restore the surface of the Properties and to comply with, or to bring the Properties into compliance with, applicable environmental laws, rules, regulations and orders, including conducting any remediation activities which may be required on or otherwise in connection with activities on the Properties), regardless of whether such condition or the events giving rise to such condition arose or occurred before or after the Closing, or

(d) any Defect, except for any right of Buyer under Article VII to an adjustment to the Base Purchase Price for such Defect or to exclude a Property for such Defect and to receive a reduction in the Base Purchase Price to account for the exclusion of such Property.

THE FOREGOING ASSUMPTIONS AND INDEMNIFICATIONS SHALL APPLY WHETHER OR NOT SUCH DUTIES, OBLIGATIONS OR LIABILITIES, OR SUCH CLAIMS, ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY.

Section 12.2. Indemnification By Seller. From and after Closing, Seller shall indemnify and hold Buyer (and its directors, officers and employees) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including without limitation court costs and consultants and attorneys fees) (individually a “Buyer’s Indemnified Loss “and collectively “Buyer’s Indemnified Losses”) arising out of

(a) any misrepresentation or breach of any warranty, covenant or agreement of Seller contained in this Agreement, or any certificate delivered at the Closing, or

(b) the ownership or operation of the Properties by Seller prior to the Closing, provided that Seller is not obligated to indemnify Buyer for the Condition of the Properties or for any Defect, and

However, Seller shall not be obligated to indemnify Buyer for Buyer’s Indemnified Losses except to the extent that the aggregate of all of Buyer’s Indemnified Losses exceeds $4,000,000.00.

Section 12.3. Notice of Claim. If indemnification pursuant to Section 12.1 or 12.2 is sought, the party seeking indemnification (the “Indemnitee”) shall give written notice to the indemnifying party of an event giving rise to the obligation to indemnify, describing in reasonable detail the factual basis for such claim, and shall allow the indemnifying party to assume and conduct the defense of the claim or action with counsel reasonably satisfactory to the Indemnitee, and cooperate with the indemnifying party in the defense thereof; provided, however, that the omission to give such notice to the indemnifying party shall not relieve the indemnifying party from any liability which it may have to the Indemnitee, except to the extent that the indemnifying party is prejudiced by the failure to give such notice and as otherwise provided in Section 15.1. The Indemnitee shall have the right to employ separate counsel to represent the Indemnitee if the Indemnitee is advised by counsel that an actual conflict of interest makes it advisable for the Indemnitee to be represented by separate counsel and the reasonable expenses and fees of such separate counsel shall be paid by the indemnifying party.

Section 12.4. No Commissions Owed. Seller agrees to indemnify and hold Buyer (and its partners and its and their affiliates, and the respective officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorneys fees) of any kind or character arising out of or resulting from any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Seller with any broker or finder in connection with this Agreement or the transaction contemplated hereby. Buyer agrees to indemnify and hold Seller (and its partners and its and their affiliates and the respective officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorneys fees) of any kind or character arising out of or resulting from any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Buyer with any broker or finder in connection with this Agreement or the transaction contemplated hereby.

ARTICLE XIII.
Casualty Losses

Section 13.1. Casualty Loss. In the event of damage by fire or other casualty to the Properties prior to the Closing, this Agreement shall remain in full force and effect, and in such event:

(a) Oil and Gas Properties. As to each such Property so damaged which is an Oil and Gas Property, then (unless Seller elects to repair such damage, which Seller shall have no obligation to do, in which case all rights to insurance proceeds, and claims against third parties, related thereto shall belong to Seller), (i) at the election of either Buyer or Seller, such Property shall be treated as if it had an Asserted Defect associated with it and the procedure provided for in Section 7.5 shall be applicable thereto (in which case, unless Buyer and Seller agree to the contrary, all rights to insurance proceeds, and claims against third parties, related thereto shall belong to Seller), or, (ii) if no such election is made by Buyer or Seller, the Purchase Price will not be adjusted, and Seller shall, at Seller’s election, either collect (and when collected pay over to Buyer) any insurance claims related to such damage, or assign to Buyer such insurance claims, and, in either event, Buyer shall take title to the Property affected by such loss without reduction of the Purchase Price.

(b) Other Properties. As to each such Property so damaged which is other than an Oil and Gas Property, Seller shall, at Seller’s election, either (i) repair such damage or replace such Property, (ii) collect (and when collected pay over to Buyer) any insurance claims related to such damage, or (iii) assign to Buyer any insurance claims related to such damage. Whether Seller elects either (i), (ii) or (iii) under this Section 13.1(b), Buyer shall take title to the Property (or the replacement property to the extent Seller elects to replace such Property under(i) ) affected by such loss without reduction of the Purchase Price and

Seller shall maintain its existing insurance coverage, and in the event of a loss which is not covered by insurance, Seller shall have no obligation to Buyer with respect thereto; provided that, if Buyer so requests, and if Seller has not repaired the damage or replaced the Property and if Buyer has not elected option (i) in Section 13.1(a) above, Seller will assign any rights it may have against third parties with respect to such damage.

ARTICLE XV.
Miscellaneous Matters

Section 15.1. Survival of Provisions. All representations and warranties contained in this Agreement, or in any certificate delivered at Closing shall survive the Closing and the delivery of the Conveyance but only for a period (“Survival Period”) of six (6) months from the Closing. All covenants of Seller or Buyer contained in this Agreement, or in any certificate delivered at the Closing shall survive the Closing and the delivery of the Conveyance, except for (a) any covenant which by its terms terminates as of a specific date and (b) the covenants set forth in Section 12.2, (and any other covenants to indemnify Buyer) which shall only survive for the Survival Period. Notice of any claim for indemnification by Buyer arising during the Survival Period must be given to the other party, within 90 days after such claim arises, as a condition precedent to the right to ▇▇▇ to enforce such claim for indemnification. Buyer may bring a suit to enforce any claim for indemnification under this Agreement, arising during the Survival Period, for a period of two (2) years after the cause of action arose with respect to any matter for which Buyer shall have given Seller written notice as provided herein.

Section 15.2. Further Assurances. After the Closing, Seller shall execute and deliver, and shall otherwise cause to be executed and delivered, from time to time, such further instruments, notices, division orders, transfer orders and other documents, and do such other and further acts and things, as may be reasonably necessary to more fully and effectively grant, convey and assign the Properties to Buyer.

Section 15.3. Gas Imbalances, Makeup Obligations. Without limitation on any other provision of this Agreement, it is expressly understood and agreed that, upon the occurrence of Closing, but effective as of the Effective Date, Buyer shall succeed to and assume the position of Seller with respect to all gas imbalances and make-up obligations related to the Properties (regardless of whether such imbalances or make-up obligations arise at the wellhead, pipeline, gathering system or other level, and regardless of whether the same arise under contract or otherwise). As a result of such succession, Buyer shall (i) be entitled to receive any and all benefits which Seller would have been entitled to receive by virtue of such position (including, without limitation, rights to produce and receive volumes of production in excess of volumes which it would otherwise be entitled to produce and receive by virtue of ownership of the Properties and rights to receive cash balancing payments), and (ii) be obligated to suffer any detriments which Seller would have been obligated to suffer by virtue of such position (including, without limitation, the obligation to deliver to others production volumes which would have otherwise been attributable to its ownership of the Properties, to deliver production to purchasers hereof without receiving full payment therefor, or to make cash balancing payments or to repay take or pay payments) and (iii) shall be responsible for any and all royalty obligations with respect to such imbalances (including, without limitation, any of the same arising out of royalties having been paid on an “entitlement” basis rather than a “receipts” basis).

Section 15.4. Waiver of Consumer Rights. Buyer hereby waives its rights under the Texas Deceptive Trade Practices — Consumer Protection Act, Section 17.41 et seq., Business and Commerce Code, a law that gives consumers special rights and protections, and any similar law in any other state to the extent such Act or similar law would otherwise apply. After consultation with an attorney of Buyer’s own selection, Buyer voluntarily consents to this waiver. To evidence Buyer’s ability to grant such waiver, Buyer represents to Seller that it (a) is in the business of seeking or acquiring, by purchase or lease, goods or services for commercial or business use, (b) has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of the transactions contemplated hereby, (c) is not in a significantly disparate bargaining position, and (d) has consulted with, and is represented by, an attorney of Buyer’s own selection in connection with this transaction, and such attorney was not directly or indirectly identified, suggested, or selected by Seller or an agent of Seller.

Section 15.5. Parties Bear Own Expenses/No Special Damages. Each party shall bear and pay all expenses (including, without limitation, legal fees) incurred by it in connection with the transaction contemplated by this Agreement. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY NEITHER PARTY SHALL HAVE ANY OBLIGATIONS WITH RESPECT TO THIS AGREEMENT, OR OTHERWISE IN CONNECTION HEREWITH, FOR ANY SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES.

Section 15.6. No Sales Taxes. No sales, transfer or similar tax will be collected at Closing from Buyer in connection with this transaction. If, however, this transaction is later deemed to be subject to sales, transfer or similar tax, for any reason, Buyer agrees to be solely responsible, and shall indemnify and hold Seller (and its affiliates, and its and their directors, officers, employees, attorneys, contractors and agents) harmless, for any and all sales, transfer or other similar taxes (including related penalty, interest or legal costs) due by virtue of this transaction on the Properties transferred pursuant hereto and the Buyer shall remit such taxes at that time. Seller and Buyer agree to cooperate with each other in demonstrating that the requirements for exemptions from such taxes have been met.

Section 15.7. Entire Agreement. This Agreement contains the entire understanding of the parties hereto with respect to subject matter hereof and supersedes all prior agreements, understandings, negotiations, and discussions among the parties with respect to such subject matter; provided that any Confidentiality Agreement executed by Buyer and Seller, or any representative of Seller, in connection with the transaction contemplated hereby remains in full force and effect and is not superseded or modified by this Agreement.

Section 15.8. Amendments, Waivers. This Agreement may be amended, modified, supplemented, restated or discharged (and provisions hereof may be waived) only by an instrument in writing signed by the party against whom enforcement of the amendment, modification, supplement, restatement or discharge (or waiver) is sought.

Section 15.9. Choice of Law. Without regard to principles of conflicts of law, this Agreement shall be construed and enforced in accordance with and governed by the laws of the state of Texas applicable to contracts made and to be performed entirely within such state and the laws of the United States of America, except that, to the extent that the law of a state in which a portion of the Properties is located (or which is otherwise applicable to a portion of the Properties) necessarily governs, the law of such state shall apply as to that portion of the property located in (or otherwise subject to the laws of) such state.

Section 15.10. Time of Essence. Time is of the essence in this Agreement.

Section 15.11. No Assignment. Neither party shall have the right to assign its rights under this Agreement, without the prior written consent of the other party first having been obtained.

Section 15.12. Successors and Assigns. Subject to the limitation on assignment contained in Section 15.11 above, the Agreement shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns.

Section 15.13. No Press Releases. Except as may be required under applicable law, prior to Closing neither party shall make any public announcement with respect to the transaction contemplated hereby without the consent of the other party.

Section 15.14. Counterpart Execution, Fax Execution. This instrument may be executed in a number of identical counterparts, each of which for all purposes is to be deemed an original, and all of which constitute collectively, one instrument. It is not necessary that each party hereto execute the same counterpart so long as identical counterparts are executed by each such party hereto. However, this Agreement shall not be binding on any party unless and until it has been executed and delivered by Buyer and CQ, SPA, EnerQuest and Baytech. This instrument may be validly executed and delivered by facsimile or other electronic transmission.

Section 15.15. Exclusive Remedy. The sole and exclusive remedy of Buyer against Seller or any of its respective directors, partners, officers, employees, and agents ( and including, specifically, Waterous International (USA), Inc. and its directors, officers, and agents) with respect to the Properties or this Agreement shall be pursuant to the express provisions of this Agreement. Without limitation of the foregoing, if the Closing occurs the sole and exclusive remedy of Buyer, for any and all (a) claims relating to any representations, warranties, covenants and agreements that is contained in this Agreement or in any certificate delivered at Closing and that survive the Closing, (b) other claims pursuant to or in connection with this Agreement and (c) other claims relating to the Properties and the purchase and sale thereof, shall be any right to indemnification from such claims that is expressly provided in this Agreement, and if no such right of indemnification is expressly provided, then such claims are hereby waived to the fullest extent permitted by law. If the Closing occurs, Buyer shall also be deemed to have waived, to the fullest extent permitted under applicable law, any right to contribution against Seller (including, without limitation, any contribution claim arising under any applicable environmental law) and any and all other rights, claims and causes of action it may have against Seller arising under or based on any federal, state or local statute, law, ordinance, rule or regulation or common law or otherwise. If the Closing does not occur due to the breach of Seller, (i) to the extent permitted by applicable law, the sole and exclusive remedy of Buyer shall be the right to specific performance under applicable law (ii) Buyer shall not be entitled to recover any monetary damages and (iii) therefore Seller agrees that in such event Buyer’s legal remedies will be inadequate and that the Properties are unique. If the foregoing limitation of Buyer’s remedy to specific performance should for any reason be legally unenforceable, then the sole and exclusive remedy of Buyer in such event shall instead be any right to recover actual, direct damages for such breach, provided that in no event shall Buyer be entitled to recover an amount in excess of an amount equal to the Deposit.

Section 15.16. Maximum Limit on Seller’s Indemnity Obligations. Anything to the contrary notwithstanding, in no event shall the Seller be obligated under this Agreement to indemnify Buyer for an aggregate amount in excess of ten percent (10%) of the Purchase Price.

Section 15.17. Imputed Knowledge and Waiver. Anything to the contrary notwithstanding, if Buyer owns any interest in any Property or acts as a operator with respect to any Property (regardless of whether or not it also owns an interest in such Property) Buyer shall be deemed to have knowledge of any Defect or breach of any representation or warranty by Seller with respect to such Property, and shall not be entitled (and hereby waives any right ) (a) to give a notice of an Asserted Defect with respect to such Property, (b) to refuse to close because of the existence of any such Defect or breach or (c) to indemnity or any other remedy with respect to any such Defect or breach.

Section 15.18. Seller’s Obligations Several Not Joint. Anything to the contrary notwithstanding, the obligations and liability of CQ, SPA, EnerQuest and Baytech, arising under and in connection with this Agreement shall several and not joint. All representations, warranties, covenants, rights and obligations of “Seller” under this Agreement relating to the Properties are made by CQ, SPA, EnerQuest and Baytech, severally with respect only to the interest owned by each, respectively, in the Properties. The representations, warranties, covenants, rights and obligations relating to the organization of “Seller”, are made individually by each only as to its business organization.

Section 15.19. Seller’s Representative. CQ, SPA, EnerQuest and Baytech hereby appoint CQ to serve as their representative and agent (“Seller’s Representative”) for all purposes in connection with the rights and duties of the Seller under this Agreement including without limitation the waiver and amendment of the rights and duties of Seller under this Agreement; the giving and receiving of notices and requests; the making of adjustments to the Base Purchase Price and, after the Closing, to the Purchase Price; the receiving of the Deposit, the Purchase Price and any adjustments to the Purchase Price in favor of Seller and any other payments due Seller under this Agreement; the allocating, and distributing of the Deposit, the Purchase Price, adjustments to the Purchase Price and any other payments due the Seller, among CQ, SPA, EnerQuest and Baytech; and doing and receiving all things provided for concerning Seller in this Agreement. CQ agrees to act as the Seller’s Representative on behalf of all the parties Seller, provided that CQ may resign as Seller’s Representative at any time upon written notice to Buyer and all the other parties Seller. Buyer shall be both entitled and obligated to act and shall act in reliance upon any and all acts and things done and performed by or agreements made with respect to all matters dealt with herein by Seller’s Representative on behalf of CQ, SPA, EnerQuest and Baytech as fully and effectively as though each had done, performed, made or executed the same.

IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the date set forth above.
