RECITALS: A. Sellers have certain oil and gas interests that they want to sell to Buyer in accordance with the terms of this Agreement. B. Buyer wants to buy all of Sellers' right, title, and interest in said oil and gas interests in accordance with the terms of this Agreement. NOW THEREFORE, for and in consideration of the terms of this Agreement, the adequacy of which is hereby acknowledged, the parties agree as follows: 1. ASSETS TO BE SOLD AND PURCHASED; RESERVATION OF SURFACE ESTATE. (a) Subject to and in accordance with the terms hereof, Sellers agree to sell and quitclaim to Buyer, without any warranty, representation, or covenant as to title, express or implied, statutory or otherwise, and Buyer agrees to purchase from Sellers, all of Sellers' right, title, and interest, if any, in and to the following real property, fixtures, and personal property, but only insofar as they are attributable to the real property described in Exhibit A hereto (the "PROPERTY"): (i) any and all oil, gas and other mineral interests, including Sellers' right, title, and interest, if any, in all: (A) oil and gas leases and any other mineral leases and related easements and rights-of-way, (B) royalties and overriding royalties, (C) production payments, (D) net profits interests, (E) reversionary mineral interests, (F) unitization, pooling, and communitization agreements, and (G) declarations and orders (including all units formed under orders, rules, regulations, or other official acts of any federal, state, or other authority having jurisdiction, and voluntary unitization agreements, designations and declarations); (ii) all fixtures, equipment, gas pipelines, water disposal gathering lines and related equipment and other personal property, to the extent relating to the wells described in Exhibit B, situated on the Property; and (iii) all contracts; lease files; abstracts and title opinions; production records; well files; permits and licenses; copies of accounting records (but excluding all general financial accounting or tax accounting records that do not pertain exclusively to the Property); electric logs and geological, engineering, and other technical data and records (subject to any contractual or other restrictions relating to the transfer of such data and records); and other files, documents and records 1 5 that directly relate to the Property; provided however, Sellers may retain copies of any or all of the foregoing. Sellers' interests, if any, in the real property, fixtures, and personal property described in subsections (i) and (ii) are sometimes collectively referred to as "OIL AND GAS PROPERTIES," or as an "OIL AND GAS PROPERTY". Sellers' interests, if any, in the Oil and Gas Properties and in the personal property described in subsection (iii) are sometimes collectively called the "ASSETS." (b) Sellers except and reserve a concurrent right to utilize any easements or right-of-way rights in and to the surface estate of the property and all rights of any nature whatsoever appurtenant or otherwise associated therewith, whether said rights-of-way are under said leases or otherwise, and such right, title, and interest does not constitute any part of the Assets. The reservation of these concurrent rights shall be in addition to and not limit the statutory, contractual, or common law rights of Buyer to use the surface estate for the development of the Oil and Gas Property described herein. 2. PURCHASE PRICE; AND TAXES. (a) The purchase price for the Assets ("PURCHASE PRICE") shall be Four Million Dollars ($4,000,000) as adjusted as provided herein. The Purchase Price shall be paid at the Closing (hereinafter defined) as hereinafter provided. Said $4,000,000, without regard to any adjustments, however, is sometimes referred to herein as the "BASE PURCHASE PRICE." (b) Buyer has paid Sellers Four Hundred Thousand Dollars ($400,000) ("DEPOSIT") by check drawn on a national bank in immediately available funds. If for any reason said check should be dishonored, then at Sellers' option, and in addition to any other rights they may have, they may terminate this Agreement. If Buyer and Sellers consummate the purchase and sale of the Assets, the Deposit shall be credited against the Purchase Price. The Deposit shall be returned to Buyer: (i) only if: (A) Sellers refuse to consummate the purchase and sale of the Assets and (B) such refusal would constitute a breach hereof, or (ii) only under the other circumstances, if any, expressly set forth herein. If Buyer fails to consummate the transactions contemplated by this Agreement, or if the transactions contemplated by this Agreement otherwise fail to close on the Closing Date (hereinafter defined), Sellers shall retain the Deposit as liquidated damages. The parties agree that damages in such an event are uncertain in amount and cannot be determined with reasonable certainty in advance, that the amount of the Deposit constitutes a fair and reasonable estimate of (and is not disproportionate to) actual Damages such a breach would cause, and is not a penalty or an inducement to perform. (c) Buyer shall pay any and all sales, use, documentary, and transfer taxes and fees imposed on this transaction, and shall pay all recording and filing fees. 3. WARRANTIES, REPRESENTATIONS, AND COVENANTS. (a) Each party, as to itself only, warrants, represents, and covenants to the other party that: 2 6 (i) It is a corporation duly organized, legally existing and in good standing under the laws of the state of its incorporation, as first set out above. (ii) It is qualified to do business and is, or at Closing will be, in good standing in each state in which the Oil and Gas Properties are located where the laws of such state require a corporation owning the Oil and Gas Properties located in such state to qualify to do business. (iii) It has full power to enter into and perform its obligations under this Agreement; the execution, delivery, and performance of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all requisite corporate action; and this Agreement has been duly executed and delivered. (iv) This Agreement, and the Assignment (hereinafter defined) to be delivered at Closing, will, when executed, delivered, and accepted, constitute each such party's legal, valid and binding obligation, enforceable in accordance with its terms, except as limited by bankruptcy or other laws applicable generally to creditor's rights and as limited by general equitable principles. (v)(A) There are no pending material suits, actions, or other proceedings to which it is a party that affect: (I) the Assets (including, as to Sellers, any actions challenging or pertaining to their title to any Assets), or (II) the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby, and (B) it shall promptly notify the other party of any such material suits, actions, or other proceedings as to which after the date hereof it receives a written threat of assertion. (vi) It shall protect, defend, indemnify, and hold harmless the other party and its affiliates, and their employees, agents, successors and assigns, from and with respect to any and all rights, claims, demands, causes of action, and legal, administrative, or arbitration proceedings, of any and every nature (collectively, "CLAIMS"), and injuries, deaths, damages, and obligations of any and every nature resulting from or that gave rise to any Claim, including liabilities, losses, costs, penalties, expenses, judgments, fines, settlements, interest, reasonable attorney's fees, and other related expenses of any nature (collectively, "DAMAGES") resulting from a breach of its warranties, representations, or covenants; provided however, that Damages shall not include consequential, special, incidental, or punitive damages. (b) Sellers warrant and represent to Buyer that other than: (i) requirements (if any) that consents to assignment of Assets, or waivers of preferential rights to purchase Oil and Gas Properties, be obtained from third parties, or (ii) requirements to obtain consents or approvals from, or to submit notices to or applications to, or actions that must be taken by, governmental entities (in their capacity as lessors of oil and gas leases, grantors of rights-of-way, or otherwise, whether similar to or different from the foregoing) in connection with the sale or conveyance of oil and gas leases, permits, or interests therein, or of rights or interests of the nature of any of the Assets, if the same are customarily obtained contemporaneously with or subsequent to such sale or conveyance; 3 7 neither their execution and delivery of this Agreement, nor its consummation of the transactions contemplated hereby, nor their compliance with the terms hereof, will violate or result in any default under its articles of incorporation or by-laws, or under any agreements to which it is a party or by which it is bound, or violate any federal, state, or local law (including statutory and case law), rule, regulation, ordinance, permit, license, order, judgment, injunction, writ, or decree of any nature (collectively "LAW") applicable to it or to the Assets. (c) Buyer warrants and represents to Sellers that: (i) It is a knowledgeable and experienced purchaser, owner and operator of oil and gas properties, has the ability to evaluate oil and gas properties, and, subject to its rights under Section 6, has been given the opportunity to investigate and evaluate (and has investigated and evaluated) the condition of the Assets to the extent it deems necessary or appropriate and is acquiring the Assets based solely upon its own investigation and evaluation and for its own account, and not with a view to or the intent to make a resale or distribution within the meaning of the Securities Act of 1933 (and the rules and regulations pertaining thereto) or a resale or distribution thereof in violation of any other applicable securities laws. (ii) With respect to any Assets that comprise leases issued by any governmental entity, it is qualified to become the successor lessee of such leases and assumes the risk of being approved as the successor lessee of such leases. (iii) Neither its execution and delivery of this Agreement, nor its consummation of the transactions contemplated hereby, nor its compliance with the terms hereof, will violate or result in any default under its articles of incorporation or by-laws, or under any agreement to which it is a party or by which it is bound, or violate any Law applicable to it or to the Assets. 4. SELLERS' DISCLAIMER OF WARRANTIES, REPRESENTATIONS, AND COVENANTS. (A) WITH RESPECT TO THE ASSETS, THIS AGREEMENT, AND THE TRANSACTIONS CONTEMPLATED HEREBY, SELLERS' WARRANTIES AND REPRESENTATIONS AS EXPRESSLY SET OUT IN SECTION 3 HEREOF AND IN THE ASSIGNMENT EXECUTED PURSUANT HERETO ARE EXCLUSIVE AND IN LIEU OF ANY AND ALL OTHER WARRANTIES, REPRESENTATIONS, AND COVENANTS, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, AND SELLERS DISCLAIM ANY AND ALL OTHER WARRANTIES, REPRESENTATIONS, AND COVENANTS, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE. (B) CONSISTENT WITH AND NOT AS A LIMITATION ON SUBSECTION (A), THE ASSETS SHALL BE PURCHASED, SOLD, AND CONVEYED "AS IS, WHERE IS", WITHOUT ANY WARRANTY, REPRESENTATION, OR COVENANT, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, RELATING TO: (I) THE CONDITION, QUANTITY, QUALITY, FITNESS FOR A PARTICULAR PURPOSE OR ANY PURPOSE, CONFORMITY TO THE MODELS OR SAMPLES OF MATERIALS, OR MERCHANTABILITY OF ANY IMMOVABLE PROPERTY, MOVABLE PROPERTY, EQUIPMENT, INVENTORY, MACHINERY, AND OTHER FIXTURES AND PERSONAL PROPERTY CONSTITUTING PART OF THE ASSETS; 4 8 (II) ANY IMPLIED OR EXPRESS WARRANTY OF FREEDOM FROM REDHIBITORY VICES OR DEFECTS OR OTHER VICES OR DEFECTS, WHETHER KNOWN OR UNKNOWN; (III) ANY AND ALL IMPLIED WARRANTIES, REPRESENTATIONS, OR COVENANTS EXISTING UNDER APPLICABLE LAW NOW OR HEREAFTER IN EFFECT; AND (IV) EXCEPT AS PROVIDED OTHERWISE IN SUBSECTION (A), WITHOUT ANY OTHER WARRANTY, REPRESENTATION, OR COVENANT, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE. (C) CONSISTENT WITH BUT NOT AS A LIMITATION ON SUBSECTIONS (A) AND (B), SELLERS ARE SELLING AND BUYER IS BUYING THE ASSETS WITH ALL DEFECTS AND FAULTS (LATENT OR APPARENT) AND IT ASSUMES THE RISK THAT ADVERSE PAST, PRESENT OR FUTURE PHYSICAL CONDITIONS MAY NOT HAVE BEEN REVEALED BY ITS INVESTIGATIONS. 5. CERTAIN COVENANTS OF SELLERS PENDING CLOSING. Between the date hereof and the Closing Date: (a) Sellers will give Buyer, its attorneys and other representatives, subject to the provisions of the Confidentiality Agreement dated January 20, 2000, heretofore executed by Buyer ("CONFIDENTIALITY AGREEMENT") and subject to any restrictions on access to the Assets imposed by agreements by which Sellers are bound, access at all reasonable times to: (i) the Assets and (ii) Sellers' records and files, to the extent located at Sellers' offices, relating to the Assets (which records and files include those relating to title, division orders, wells, production, accounting, marketing, equipment inventories, and production, severance and ad valorem taxes). Notwithstanding the foregoing, Sellers shall not be obligated to provide Buyer with access to any files or records that it cannot legally provide to Buyer without, in Sellers' opinion, breaching or risking a breach of confidentiality agreements. All such files and records are being made available to Buyer (whether pursuant to this Section or otherwise) as an accommodation, and without representation, warranty, or covenant, express or implied, statutory or otherwise, as to the accuracy and completeness of such materials. (b) To the extent Sellers are the operator of any Oil and Gas Properties, they will continue such operation in the ordinary course of their business; and where they are not the operator of any Oil and Gas Properties, they will continue their actions as a non-operator in the ordinary course of their business. Sellers will not sell or dispose of any portion of the Assets without Buyer's prior consent, which shall not be unreasonably withheld. (c)(i)(A) Sellers shall review their own records (including all operating agreements, to which they are a party, applicable to the Oil and Gas Properties) to identify: (I) all preferential rights to 5 9 purchase any Assets, (II) all rights to require that consents to assignment of any Assets be obtained, and (III) the parties holding any of such rights. In identifying the foregoing, Sellers shall have no obligation to review anything other than their own records. (B) Sellers will request, from the parties so identified under subsection (A) and from any other third parties identified by Buyer in a Defect Notice (hereinafter defined) given to Sellers by the Defect Date (hereinafter defined) (and in accordance with the documents creating such rights), waivers of the preferential rights to purchase and requirements that consents to assignment be obtained which were so identified. Sellers shall have no obligation hereunder other than to so attempt to identify such preferential rights and requirements for consents to assignment and to so request such waivers, and shall have no obligation to obtain such waivers. Unless Buyer can establish that Sellers failed to fulfill their obligations under this subsection, Buyer shall protect, defend, indemnify and hold Sellers harmless from and against all Claims and Damages arising out of any failure to obtain waivers of preferential rights to purchase or requirements for consents to assignment with respect to any transfer by Sellers to Buyer of any Assets and with respect to any subsequent transfers. (ii) If the holder of a preferential right to purchase an Asset fails or refuses to give such waiver and instead exercises such right, Sellers will tender to such holder (at a price equal to the amount specified in Exhibit B hereto for the wells located on such Asset and for the units in which such Asset participates, reduced appropriately, as determined by Sellers, if less than the entire Asset should be tendered, unless it is determined that a greater or lesser price is required) the interest in the Asset affected by such preferential right. If such interest in such Asset is actually sold to such holder, it will be excluded from the transaction contemplated hereby and the Purchase Price will be reduced by the amount paid to Sellers by the holder exercising such right; provided however, that if the holder of such right believes the Allocated Value (hereinafter defined) is too high, Sellers shall promptly notify Buyer, and Sellers and Buyer shall cooperate to address such assertion by the holder of such right. (d) Notwithstanding anything in this Section to the contrary: (i) Sellers may take any action prohibited by this Section if reasonably necessary under emergency conditions, provided that Buyer is notified as soon as practicable thereafter; (ii) except to the extent a "DEFECT" ( hereinafter defined) may result therefrom, Sellers shall have no liability to Buyer for any incorrect payment of delay rentals, royalties, shut-in royalties or similar payments or for any failure to make such payments; and (iii) Sellers' failure to comply with any of the requirements of this Section shall not be deemed a default by Sellers hereunder or entitle Buyer to not close the transactions contemplated hereby, unless such failure has a materially adverse impact on the value of the Assets taken as a whole. 6. DUE DILIGENCE AND ENVIRONMENTAL REVIEWS. (a)(i) To the extent deemed appropriate by Buyer, it may conduct, at its sole cost and risk, such title examinations and, subject to any restrictions to which Sellers are bound, any other reasonable examinations and investigations as it may choose with respect to the Assets; provided however, environmental examinations and investigations shall be governed by subsection (b). If as a result of such examinations and investigations Buyer identifies any matters that constitute Defects, and if there are any Defects that Buyer is unwilling to waive, Buyer must notify Sellers of such Defects ("DEFECT NOTICE") promptly following its discovery of such Defects, but in no event later than June 23, 2000 ("DEFECT DATE"). 6 10 Buyer may not give notice of any Defects after the Defect Date, and must accept all Defects, if any, discovered after the Defect Date. (ii) To be effective, a Defect Notice must include: (A) a brief description of the matter constituting the alleged Defect, (B) the title opinion, expert's report, or other documentation on which the alleged Defect is based, (C) such supporting documents reasonably necessary for Sellers to determine if a Defect actually exists, and (D) Buyer's estimate of the diminution in the sum to be paid at Closing resulting from such alleged Defect. Alleged Defects for which Buyer provides a valid Defect Notice no later than the Defect Date are herein called "ASSERTED DEFECTS." (iii) Except for Asserted Defects, all matters that might otherwise constitute a Defect are waived for all purposes hereof. With respect to any Asserted Defect, Sellers shall have the right but not the obligation to: (A) attempt to cure it prior to Closing, (B) require that the Closing take place, deposit in an escrow account the portion of the Purchase Price paid by Buyer and attributable to the Asset having the Asserted Defect, and attempt to cure such Asserted Defect within thirty (30) days after the Closing, and Sellers' right under this clause (B) may be exercised at any time before the Closing; or (C) elect not to cure the Asserted Defect and adjust the Purchase Price as provided in Section 7. If Sellers, on or before the Closing, exercise any such right as to an Asserted Defect, then such Asserted Defect shall be deemed to have been cured. (iv) With respect to any Oil and Gas Property, if a title opinion or any other materials reviewed by Buyer indicates Sellers have a "NET REVENUE INTEREST" (hereinafter defined) greater than that specified on Exhibit B, then Buyer shall promptly inform Sellers of the same, but in any event at least five (5) days prior to the Closing. If Sellers or Buyer determine that Sellers are entitled to a Net Revenue Interest in any Asset in excess of that set forth on Exhibit B ("NRI INCREASE"), notice shall promptly be given to the other party, and the adjustments to be made under Section 7 shall include adjustments which are the subject of such notice. (b)(i)(A) To the extent, if any, that Sellers have the right to grant Buyer the right to do so, Buyer may, upon at least four (4) day's notice to Sellers, enter upon the Oil and Gas Properties to conduct an environmental assessment of the Assets at Buyer's sole cost and risk. (B) Consistent with but not as a limitation on the foregoing, Buyer shall protect, defend, indemnify, and hold Sellers and anyone else owning an interest in the Oil and Gas Properties harmless from and against any Claims and Damages resulting from the presence or activities of Buyer or its agents on the Oil and Gas Properties in the course of conducting its assessment activities. (ii)(A) In conducting its assessment, and subject to subsection (i), Buyer may enter upon the Oil and Gas Properties, without disrupting operations thereon, and inspect the same, conduct soil and water tests and borings, and generally conduct such tests, examinations, investigations, and studies as may be necessary or appropriate for the preparation of appropriate engineering and other reports in relation to the Oil and Gas Properties, their condition, and the presence of Hazardous Substances (hereinafter defined). Any such assessment shall be concluded no later than June 26, 2000 ("ENVIRONMENTAL ASSESSMENT DATE"). If there are any Oil and Gas Properties as to which Sellers do not have the right to grant Buyer the right to conduct an assessment, or if as a result of Buyer's environmental assessment any particular Oil and Gas Property is determined to be in material violation of environmental Laws, then Buyer, no later than the 7 11 Environmental Assessment Date, may notify Sellers that Buyer wants to exclude such Oil and Gas Property from this Agreement (and such notice, if and to the extent regarding a violation of environmental Laws, shall provide in reasonable detail the Law that was violated, the manner in which such Law was violated, and sufficient information to substantiate the violation), in which event said Oil and Gas Property shall be excluded and the Purchase Price shall be reduced, with such reduction in the Purchase Price being determined as provided in Section 7. After the Environmental Assessment Date: (I) Buyer may not request that any Oil and Gas Property be excluded from this Agreement due to Sellers not having the right to grant Buyer the right to conduct an environmental assessment as to such Oil and Gas Property or due to any violation of environmental Laws as to such Oil and Gas Property, and (II) Buyer shall be deemed to have inspected the Oil and Gas Properties or waived its right to inspect the Oil and Gas Properties for all purposes and satisfied itself as to their physical and environmental condition, both surface and subsurface, including conditions specifically related to the presence or release of any substance or material defined or designated as hazardous or toxic waste, hazardous or toxic material, hazardous or toxic substance, or other similar term, by any Law relating to the environment (collectively, "HAZARDOUS SUBSTANCES"). (B) Sellers have been performing environmental remediation operations with respect to substances that had been deposited or otherwise disposed in nine (9) pits in the portion of the Oil and Gas Properties known as Bagley Field. The nature of such operations has been, and is, using windmill powered pumps to remove Benzene from the water. The nine (9) pits for which such operations are currently being conducted are listed on Exhibit D. Such environmental remediation operations will not be completed as of the Closing Date, and as of the Effective Date, Sellers shall be responsible for all environmental remediation work and any costs associated therewith regarding said nine (9) pits. Sellers shall protect, defend, indemnify, and hold Buyer harmless from any claims, fines, or damages associated with the performance of environmental remediation operations on pits described in Exhibit D herein. Notwithstanding anything herein to the contrary, the Purchase Price shall not be reduced, and no Oil and Gas Property may be excluded, due to any matters relating to the need to continue environmental remediation operations with respect to said nine (9) pits. Sellers reserve the right to continue, at no cost to Sellers, disposing of produced water from field remediation operations, into the O. G. State No. 2 disposal well. Buyer shall have the right to test Sellers' water from these operations. (iii)(A) Buyer shall provide Sellers with a copy of any environmental assessment and other reports, and all supporting data and other documentation, promptly upon completion of the assessment. Buyer shall keep any data or information acquired by such examinations and the results of all analyses of such data and information strictly confidential and shall not disclose them to anyone without Sellers' prior written approval, which need not be given by Sellers. (B) The consent required by subsection (A) shall not apply to a disclosure to a governmental agency that Buyer believes upon written advice of counsel is required by Law; provided however, that in such event, Buyer shall give notice to Sellers (which notice shall describe in a reasonably detailed manner the legal grounds on which such advice is based) at least ten (10) days prior to making such disclosure, and shall take into account any comments Buyer may receive from Sellers. Sellers shall have the right to contest the need to disclose any information, and Buyer shall protect, defend, indemnify, and hold 8 12 Sellers harmless from any Claims or Damages resulting from any disclosure that was not required by Law. Sellers shall protect, defend, indemnify, and hold Buyer harmless from Sellers' acts with respect to (1) withholding consent in accordance with subsection (A) herein, or (2) exercising Sellers' right to contest the need to disclose any information contemplated herein. (c) As used herein, "DEFECT" means any matter, other than a "PERMITTED ENCUMBRANCE" (hereinafter defined), which causes one or more of the following to be a correct statement: (i) Sellers' ownership of an Asset is such that, with respect to a well or unit listed on Exhibit B, such ownership: (A) is insufficient to entitle it to receive a decimal share of the oil, gas and other hydrocarbons produced from, or allocated to, such well or unit that is at least equal to the decimal share set forth on Exhibit B in the column "Net Revenue Interest" or (B) obligates it to bear a decimal share of the cost of operating such well or unit ("OPERATING INTEREST") greater than the decimal share set forth on Exhibit B in the column "Operating Interest" without a proportionate increase in the corresponding Net Revenue Interest set forth on such Exhibit; (ii) Sellers' ownership of an Oil and Gas Property is subject to an outstanding and valid mortgage, deed of trust, other lien or encumbrance, or other adverse claim or imperfection in title, which if asserted would cause either subsection (i)(A) or (i)(B) to be a correct statement; or (iii) Sellers have inaccurately and materially represented or failed to represent the amount of any gas imbalances. (iv) Any product sales contracts that have not been disclosed to Buyer before closing. (d) As used herein, "PERMITTED ENCUMBRANCE" shall mean any and all of the following: (i) The conditions, restriction, exceptions, reservations, limitations and all other terms contained in the agreements and instruments in the chain of title that creates or reserves to Sellers their interest in any Asset, provided that the same do not reduce Sellers' Net Revenue Interest in the affected Asset to less than that set forth on Exhibit B; (ii) Royalties, overriding royalties (including those specifically described on Exhibit A), division orders, reversionary interests, production payments, net profits interests and similar burdens affecting any Oil and Gas Property if the net cumulative effect of such burdens does not reduce Sellers' Net Revenue Interest in the affected Asset to less than that set forth on Exhibit B; (iii) Preferential rights to purchase, requirements that third party consents be obtained for assignments, and agreements of a similar nature, with respect to which waivers or consents shall have been obtained from the appropriate parties, or the appropriate time period for asserting such rights shall have expired without an exercise of such rights; (iv) Taxes and assessments which are not yet delinquent or which are being contested by Sellers in good faith; (v) Conditional rights of reassignment requiring ninety (90) days or less notice to the holder of such rights; the conditions which have not occurred or will not occur prior to Closing. 9 13 (vi) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect to surface operations, pipelines, logging, canals, ditches, reservoirs or the like; conditions, covenants or other restrictions; easements for streets, alleys, highways, pipelines, telephone lines, power lines, railways and other easements or rights-of-way on, over or with respect of any Asset which do not materially and adversely affect the Asset affected thereby or its current use; (vii) Any obligations or duties affecting an Asset to any municipality or public authority with respect to any franchise, grant, license or permit and all applicable Laws of any governmental authority; (viii) Existing operating agreements, unit agreements, gas purchase contracts and any and all other agreements that are typical in the oil and gas exploration, development, production or extraction business or in the business of processing of gas and gas condensate or production for the extraction of proper products therefrom, to the extent that the same do not reduce Sellers' Net Revenue Interest in the affected Asset to less than that set forth on Exhibit B; (ix) Any other defect or imperfection in title which would customarily be waived by a reasonable person engaged in the business of owning and operating oil and gas properties; and (x) Any other matter waived or deemed to be waived by Buyer pursuant to the provisions of subsection (a). (e) With respect to all Assets conveyed to Buyer hereunder: (I) BUYER SHALL BE DEEMED TO HAVE: (A) INSPECTED, OR TO HAVE WAIVED ITS RIGHT TO INSPECT, THE ASSETS FOR ALL PURPOSES, AND (B) SATISFIED ITSELF AS TO THEIR PHYSICAL AND ENVIRONMENTAL CONDITION, BOTH SURFACE AND SUBSURFACE, INCLUDING CONDITIONS SPECIFICALLY RELATED TO THE PRESENCE, RELEASE, OR DISPOSAL OF SOLID WASTES, ASBESTOS, OTHER MANMADE FIBERS, NATURALLY OCCURRING RADIOACTIVE MATERIALS, AND OTHER HAZARDOUS SUBSTANCES IN, ON, OR UNDER THE OIL AND GAS PROPERTIES. (II) BUYER SHALL BE DEEMED TO HAVE RELIED SOLELY ON ITS OWN INSPECTION OF THE ASSETS, AND AS PROVIDED IN SECTION 4, SELLERS ARE SELLING AND BUYER IS BUYING ALL ASSETS "AS IS, WHERE IS." CONSISTENT WITH BUT NOT AS A LIMITATION ON THE FOREGOING, SELLERS MAKE NO WARRANTY, REPRESENTATION, OR COVENANT, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, AS TO THE ACCURACY OR COMPLETENESS OF ANY DATA, REPORTS, RECORDS, PROJECTIONS, INFORMATION, OR OTHER MATERIALS NOW, HERETOFORE, OR HEREAFTER FURNISHED OR MADE AVAILABLE TO BUYER IN CONNECTION WITH THIS AGREEMENT, INCLUDING PRICING ASSUMPTIONS OR QUALITY OR QUANTITY OF HYDROCARBON RESERVES (IF ANY) ATTRIBUTABLE TO THE ASSETS OR THE ABILITY OR POTENTIAL OF THE ASSETS TO PRODUCE HYDROCARBONS OR THE ENVIRONMENTAL CONDITION OF THE ASSETS OR ANY OTHER MATERIALS 10 14 FURNISHED OR MADE AVAILABLE TO BUYER BY OR ON BEHALF OF SELLERS. ANY AND ALL SUCH DATA, REPORTS, RECORDS, PROJECTIONS, INFORMATION, AND OTHER MATERIALS FURNISHED BY OR ON BEHALF OF SELLERS TO BUYER ARE PROVIDED TO BUYER AS A CONVENIENCE AND SHALL NOT CREATE OR GIVE RISE TO ANY LIABILITY OF OR AGAINST SELLERS, AND ANY RELIANCE ON OR USE OF THE SAME SHALL BE AT BUYER'S SOLE RISK. 7. CERTAIN PURCHASE PRICE ADJUSTMENTS. (a) If in connection with the due diligence review under Section 6 either: Asserted Defects are presented to Sellers and Sellers are unable or unwilling to cure such Asserted Defects prior to Closing, Buyers have elected 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, or an NRI Increase occurs, or an Oil and Gas Property is excluded under Section 6(b)(ii), or 6(c) then: (i)(A) If the Asserted Defect is a mortgage, deed of trust, lien, encumbrance or other charge which is undisputed and liquidated in amount, then the adjustment shall be the amount necessary to be paid to remove the Asserted Defect from the affected Oil and Gas Property; (B) If there is: (I) an Asserted Defect or NRI Increase that represents a discrepancy between the Net Revenue Interest that Sellers are entitled to receive from any Oil and Gas Property and the Net Revenue Interest stated on Exhibit B, and (II) an Operating Interest change proportionate to the change in the Net Revenue Interest resulting from the Asserted Defect or NRI Increase, then the amount of the adjustment shall be the product of the value allocated by Buyer (and Buyer represents said value was allocated in good faith) to such Oil and Gas Property as set forth on Exhibit B ("ALLOCATED VALUE") multiplied by a fraction, the numerator of which shall be the change in the Net Revenue Interest and the denominator of which shall be the Net Revenue Interest set forth on Exhibit B; and (C) If an Oil and Gas Property is excluded under Section 6(b)(ii) or 6(c), then the Purchase Price shall be reduced by the Allocated Value of the Wells located on such Oil and Gas Property. (ii) If the Asserted Defect represents an obligation, encumbrance, burden, discrepancy or charge upon or other defect in title to the affected Oil and Gas Property of a type not described in subsections (i)(A) or (i)(B), the adjustment amount shall be determined by taking into account the Allocated Value of the Oil and Gas Property so affected, the portion of the Oil and Gas Property affected by the Asserted Defect, the legal effect of the Asserted Defect, the potential economic effect of the Asserted Defect over the life of the affected Oil and Gas Property and such other factors as are necessary to make a proper evaluation of the value of the Asserted Defect; provided further, that if the parties cannot agree upon an appropriate adjustment in light of the foregoing factors, then subject to subsection (b), either Buyer or Sellers may elect to exclude such Oil and Gas Property from the transaction contemplated hereby, and the Purchase Price will be reduced by the Allocated Value of the wells located on such Oil and Gas Property and the units in which the related Oil and Gas Property participates. 11 15 (iii) Notwithstanding anything herein to the contrary: (A) the aggregate reduction attributable to the effect of all Asserted Defects related to a given Oil and Gas Property shall not exceed the Allocated Value of the Wells located on such Oil and Gas Property; and (B) no reduction shall be made with respect to an Asserted Defect if the diminution in the Allocated Value regarding such Oil and Gas Property resulting therefrom regarding said asset will not exceed Twelve Thousand Five Hundred Dollars ($12,500.00). (b)(i) If the aggregate Purchase Price reductions which would result under subsections (a) and (c) do not exceed two percent (2%) of the Base Purchase Price, then the Purchase Price shall not be adjusted, and none of the Oil and Gas Properties which would be excluded by such procedure shall be excluded. (ii) If the aggregate Purchase Price reductions which would result under subsections (a) and (c) exceed two percent (2%) of the Base Purchase Price, the Purchase Price shall be adjusted by the amount by which such decreases exceed two percent (2%) of the Base Purchase Price. If the Purchase Price increase which would result under subsection (a) exceeds two percent (2%) of the Base Purchase Price, the Purchase Price shall be adjusted by the amount by which such increase exceeds two percent (2%) of the Base Purchase Price. (c) If Buyer, prior to the Defect Date, provides Sellers with evidence reasonably satisfactory to Sellers that the disposal well operated by Sellers in the Bagley Field does not pass the mechanical integrity test required by Law, then: (i) prior to Closing, Sellers shall repair said disposal well so as to bring it into compliance with Law, or (ii) the Base Purchase Price shall be reduced by an amount equal to that necessary to bring said disposal well into compliance with Law. (d) If the net aggregate amount of all Purchase Price reductions under this Agreement, regardless of the reason for such reductions, exceeds five percent (5%) of the Base Purchase Price, either party may terminate this Agreement by giving notice to the other party within ten (10) days of the date it was determined that the Purchase Price reduction would exceed said five percent (5%), in which event this Agreement shall terminate and the Deposit shall be returned to Buyer. Upon such termination, the parties shall have no further obligations to one another hereunder (other than the indemnification obligations under Sections 3(a)(vi) and 6(b), and the obligations under and Sections 11(c), 14 and 19 - 26, which will survive such termination).
