The Purchase Price shall be adjusted as follows: a. UPWARD ADJUSTMENTS TO THE PURCHASE PRICE. The Purchase Price shall be adjusted upward by the amount of all actual costs and expenses attributable to the Assets and incurred with respect to an event or activity occurring subsequent to the Effective Time and paid by Seller, including capital expenses, lease rentals, lease maintenance costs, royalties, water disposal charges, surface damages and/or rental expenses, Taxes (as that term is defined in Article 10), drilling expenses, workover expenses, geological, geophysical and other exploration expenditures that are attributable to the maintenance and operation of the Assets, but, as to overhead charges, limited to those overhead charges incurred under the terms of the Contract Operator Agreement between GeoMet Operating Company, Inc. and KLT Gas Inc. dated December 19, 1999, effective May 1, 1999 (the "PROPERTY EXPENSES"). The Purchase Price shall be adjusted upward by the proceeds of production occurring before the Effective Time and received by Buyer, net of royalties and taxes measured by production, plus an amount equal to production from the Assets that occurred before the Effective Time but, because such production is in pipelines or in processing, had not been sold as of the Effective Time, times the price for which production from the Assets was sold immediately prior to the Effective Time. To the extent that there are any pipeline imbalances, if the net of such imbalances is an overdelivery imbalance (that is, at the Effective Time, Seller has delivered more gas to the pipeline than the pipeline has redelivered for Seller), the Purchase Price shall be adjusted upward by the first-of-the month price of spot gas delivered to pipelines for Colorado Interstate Gas Company (Rocky Mountains) as reported in Inside F.E.R.C.'s GAS MARKET REPORT for the month in which the Effective Time occurs times the net overdelivery imbalance in MMbtus. In the event such publication shall cease to be published, the parties shall select a comparable publication. b. DOWNWARD ADJUSTMENTS TO THE PURCHASE PRICE. The Purchase Price shall be adjusted downward by the amount of all Property Expenses that remain unpaid by Seller and that have been paid by Buyer, that are incurred with respect to an event or activity occurring prior to the Effective Time, and an amount equal to the sum of all adjustments provided for in this Agreement for Title Defects, Environmental Defects, and Casualty Losses (as those terms are hereinafter defined). The Purchase Price shall be adjusted downward by the proceeds of production occurring on or after the Effective Time and received by Seller, net of royalties and taxes measured by production. To the extent that there are any pipeline imbalances, if the net of such imbalances is an underdelivery imbalance (that is, at the Effective Time, Seller has delivered less gas to the pipeline than the pipeline has redelivered for Seller), the Purchase Price shall be adjusted downward by the first-of-the-month price of -5- spot gas delivered to pipelines for Colorado Interstate Gas Company (Rocky Mountains) as reported in Inside F.E.R.C.'s GAS MARKET REPORT for the month in which the Effective Time occurs times the net underdelivery imbalance in MMbtus. In the event such publication shall cease to be published, the parties shall select a comparable publication. c. PRELIMINARY SETTLEMENT STATEMENT. The Purchase Price shall be adjusted at Closing pursuant to the "PRELIMINARY SETTLEMENT STATEMENT" prepared by Seller and submitted to Buyer three Business Days prior to the Closing Date for Seller's comment and review. "BUSINESS DAY" means a day on which commercial banks located in Denver, Colorado are open for business. The Preliminary Settlement Statement shall set forth all Purchase Price adjustments and associated calculations but only to the extent the adjustments provided for in Sections 2.3.a. and 2.3.b. are known at the time the Preliminary Settlement Statement is prepared, with the resulting amount being called THE "CLOSING AMOUNT." d. FINAL SETTLEMENT STATEMENT. After Closing, the Purchase Price shall be adjusted pursuant to a "FINAL SETTLEMENT STATEMENT" prepared by Seller and delivered by Seller to Buyer on or before 120 days following the Closing Date, setting forth each adjustment or payment that was not finally determined as of the Closing and showing the calculation of such adjustment and the resulting Purchase Price. On or before 15 Business Days after Buyer's receipt of Seller's proposed Final Settlement Statement, Buyer shall deliver to Seller a "written report" containing Buyer's proposed changes to the Final Settlement Statement. The parties shall agree with respect to the changes proposed by Buyer no later than 15 Business Days after receipt of Buyer's "written report," and the date on which the Final Purchase Price is established shall be called the "FINAL SETTLEMENT DATE." Any payments due from one party to the other as a result of the Final Settlement Statement shall be made within five days of the Final Settlement Date. i. In addition to the foregoing, the Final Settlement Statement shall provide for the following: (x) the Gross Revenues from sales of natural gas produced from the Assets during the period from 7:00 a.m. on July 1, 2000 through 6:59 a.m. on October 1, 2000 shall be reduced by all royalty payments and other lease burdens in existence on July 1, 2000, and appearing of record in Las Animas County, Colorado, or in the Records made available to Buyer prior to the date of this Agreement, Taxes, gathering charges, lease operating expenses, and capital expenditures related to such production. "GROSS REVENUES" are the actual proceeds from natural gas production from the Assets during such period. (y) If the net amount from (x) exceeds $600,000, the Purchase Price will be adjusted downward by the amount of such excess. 2.4 GAS PRICE ADJUSTMENT TO PURCHASE PRICE. a. GENERAL. In addition to the Purchase Price adjustments described in Section 2.3, an additional adjustment to the Purchase Price, in accordance with this Section 2.4, shall be made as of January 1, 2003, based on the Benchmark Price (hereinafter defined), as determined in accordance with this Section 2.4. "BENCHMARK PRICE" shall mean the "fixed" natural gas price, expressed in MMbtus, quoted by a Designated Market-Maker -6- (hereinafter defined), acting in a commercially reasonable manner, for a fixed/floating forward swap for a notional quantity of 10,000 MMbtu per day with monthly settlements and having a term of 5 years that such Designated Market-Maker would be willing to enter into on January 1, 2003 with a creditworthy counterparty and with a floating price based upon Inside F.E.R.C.'S GAS MARKET REPORT for the first of the month delivered to pipeline index for "Colorado Interstate Gas Company -- Rocky Mountains" (the "RELEVANT INDEX"). If the Relevant Index no longer exists on January 1, 2003, then such Index shall be replaced by an index that, in the commercially reasonable opinion of the Designated Market-Maker, most accurately reflects the fair market value of natural gas delivered in the Rocky Mountain region during such 5- year period. "DESIGNATED MARKET-MAKER" shall mean one of the following entities (or the affiliate of such an entity, whose primary business is in the making of markets for swaps and other derivatives or like natural gas price risk management products): Bank One, NA; J. Aron (Goldman Sachs); Enron Corporation; Bankers Trust; and Bank of America. b. DETERMINATION OF BENCHMARK PRICE. On the last Business Day of 2002, between 2:15 p.m. and 3:00 p.m. Central Standard Time, Buyer and Seller shall each obtain a written quote (which shall indicate the time such quote was given on the face of such writing) from a Designated Market-Maker that will serve as the basis for the Benchmark Price. By not later than the end of such Business Day, each party shall have transmitted a copy of the written quote to the other party. The Benchmark Price shall then be determined by taking the arithmetical average of the Buyer's quote and the Seller's quote. If either party fails timely to obtain such written quote, and/or to timely provide it to the other party, then the Benchmark Price shall be determined solely on the basis of the quote obtained by the party who timely (i) obtained such quote and (ii) provided it to the other party. If both parties fail to timely (i) obtain such quote and (ii) provide such quote to the other party, then Buyer and Seller shall endeavor to obtain such quote and provide such quote to the other party on the first Business Day of 2003, until such quote has been timely obtained and provided to the other party by at least one of the parties. c. AMOUNT OF GAS PRICE ADJUSTMENT TO PURCHASE PRICE. The following chart sets forth (i) the amount of any post-closing purchase price adjustment payable under this Section 2.4, (ii) the party to whom such payment is to be made and (iii) the relevant Benchmark Price to be used in determining the amount of such payment, and the party to whom such payment shall be due: BENCHMARK PRICE PARTY RECEIVING AMOUNT OF (PER MMBTU) PAYMENT PAYMENT (less than or Buyer $5 million equal to) $2.56 (greater than) Seller $1 million $2.56 but (equal to or less than) $2.66 (greater than) Seller $2 million $2.66 but (equal to or less than) $2.77 (greater than) Seller $3 Million $2.77 but (equal to or less than) $2.87 -7- BENCHMARK PRICE PARTY RECEIVING AMOUNT OF (PER MMBTU) PAYMENT PAYMENT (greater than) Seller $4 million $2.87 but (less than) $2.97 (equal to or Seller $5 million greater than) $2.97 but (less than) $3.07 $3.07 or higher Seller $6 million d. PAYMENT OF PURCHASE PRICE ADJUSTMENT. The purchase price adjustment calculated in accordance with Section 2.4.c above, shall be paid to the appropriate party, as determined in accordance with Section 2.4.c, in immediately available funds by not later than January 31, 2003. Past due payments shall bear interest until paid at the lesser of (i) the Reference Rate (defined below) or (ii) the highest rate permitted by applicable law. "REFERENCE RATE" shall mean the rate announced by Bank One, NA, as the rate it charges to its most favored commercial customers. It is specifically understood and agreed that all payments under this Section 2.4 shall be determined solely on the basis of the Benchmark Price, without reference to any other factors, including but not limited to any quantities of Hydrocarbons that shall have been produced, or that may be producible from, the Assets. e. KLT GUARANTY AGREEMENT. KLT agrees to guarantee any and all post-closing purchase price adjustments in favor of Buyer payable under Section 2.4, and execute and deliver to Buyer a Guaranty Agreement substantially in the form of Exhibit E. 2.5 ALLOCATED VALUES. Seller and Buyer agree to allocate the Purchase Price among the Assets as set forth in EXHIBIT B ("ALLOCATED VALUES"). Seller and Buyer agree that the Allocated Values have been made in accordance with the fair market value of the Assets and shall apply for the purpose of Section 1060 of the Internal Revenue Code of 1986 (as amended and together with any regulations promulgated thereunder, the "CODE"). Seller and Buyer agree (and each agrees to cause its affiliates) to report the federal, state and local income and other tax consequences of the transaction contemplated herein, and in particular to report the information required under Section 1060(b) of the Code in a manner consistent with the Allocated Values. Seller and Buyer further agree (and each agrees to cause its affiliates) to not take any tax position inconsistent with the Allocated Values in connection with the examination of tax returns, refund claims or litigation, investigations or other proceedings involving tax returns. ARTICLE 3 DUE DILIGENCE REVIEW 3.1 ACCESS TO RECORDS. Prior to Closing and subject to Section 9.7, Seller will disclose and make available to Buyer and its representatives at Seller's office and at the offices of Seller's representatives and during Seller's normal business hours, all Records in Seller's possession or control relating to the Assets for the purpose of permitting Buyer to perform its due diligence review including, but not limited to, all well, lease, unit and title files and title opinions. Seller agrees to cooperate with Buyer in Buyer's efforts to obtain, at Buyer's sole expense, such additional -8- information relating to the Assets as Buyer may reasonably request. Seller is not required to provide records or data which Seller is prevented by contractual obligations with third parties from disclosing. 3.2 NO REPRESENTATION OR WARRANTY. Except as to the Material Agreements, Seller makes no representation or warranty as to the accuracy or completeness of the Records. Buyer agrees that any conclusions drawn from the Records shall be the result of its own independent review and judgment and shall not be based on interpretations or analysis in Seller's files.

Other than matters which are violative of Seller's special warranty set out in EXHIBIT H, any matters not described in a written Notice of Title Defect as provided above shall conclusively be deemed to have been waived and accepted by Buyer, and shall be deemed Permitted Encumbrances hereunder. b. DEFECT ADJUSTMENTS AND THRESHOLDS. The parties shall proceed as follows: i. Seller shall have the option of attempting to cure such Title Defects to the satisfaction of Buyer on or before the Closing Date, which option shall be communicated to Buyer no later than 5:00 p.m. Mountain Time on October 18, 2000; ii. Seller may contest the Defect Value by so notifying Buyer. If Buyer and Seller are unable to agree on the Defect Value (agreement shall result in the "ACTUAL DEFECT VALUE"), then Seller or Buyer may submit such Defect Value dispute to a mutually agreeable, duly licensed, petroleum engineering, geological, or accounting firm, in accordance with the expertise required to determine the Actual Defect Value, which firm shall determine the Actual Defect Value and such determination shall be final and binding upon Seller and Buyer.

If Seller does not elect to cure or is unable to cure such Title Defects to the satisfaction of Buyer on or before the Closing Date or such later date as is mutually agreed to by the parties, Buyer shall have the option to either accept assignment of the Asset affected by such Title Defect, and the Purchase Price shall be adjusted downward by the Defect Value or Actual Defect Value, as applicable, or to exclude such Asset from this Agreement (collectively, the "EXCLUDED ASSETS"). If Buyer elects to exclude such Assets, the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of the Excluded Assets; iv. There shall be no reduction to the Purchase Price under Section 4.4.b.iii unless Seller's share of a proposed reduction as to any single incident exceeds $50,000.00; this shall be determined on an incident by incident basis. In addition, if Seller's share of the proposed reduction under Section 4.4.b.iii as to any single incident exceeds $50,000.00, there shall be no reduction to the Purchase Price until such time as the total of these excess amounts (over $50,000.00) exceeds $500,000.00 (the "TITLE THRESHOLD AMOUNT") but, in such event, the Purchase Price reduction shall be inclusive of the Title Threshold Amount.

In the event of any loss described in Section 4.5.b., Seller shall either (i) at the Closing pay to Buyer all sums paid to Seller by reason of such destruction less any costs and expenses incurred by Seller in collecting same, or (ii) commit, use, or apply such sums (less any costs and expenses incurred by Seller in collecting same) to repair, restore or replace such damaged or taken Assets. To the extent the insurance proceeds, condemnation awards or other payments are not committed, used or applied by Seller prior to the Closing Date to repair, restore or replace such damaged or taken Assets, Seller shall at the Closing pay to Buyer all sums paid to Seller by reason of such destruction or taking, less any costs and expenses incurred by Seller in collecting same. In addition and to the extent such proceeds, awards or payments have not been committed, used or applied by Seller in repair, restoration or replacement as aforesaid, Seller shall assign, transfer and set over unto Buyer, without recourse against Seller, all of the right, title and interest of Seller in and to any claims against third parties with respect to the event or circumstance causing such loss and any unpaid insurance proceeds, condemnation awards or other payments arising out of such destruction or taking, less any costs and expenses incurred by Seller in collecting same. Any such funds which have been committed by Seller for repair, restoration or replacement as aforesaid shall be paid by Seller for such purposes or, at Seller's option, delivered to Buyer upon Seller's receipt from Buyer of adequate assurance and indemnity from Buyer that Seller shall incur no liability or expense as a result of such commitment.

The indemnifications contained in Section 15.3 shall be implemented as follows: a. COVERAGE. Such indemnity shall extend to all Losses suffered or incurred by the indemnified party. b. CLAIM NOTICE. The party seeking indemnification under the terms of this Agreement ("INDEMNIFIED PARTY") shall submit a written "CLAIM NOTICE" to the other party ("INDEMNIFYING PARTY") which, to be effective, must state: (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with supporting documentation, and (iii) a list identifying to the extent reasonably possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by the -31- Indemnifying Party to the extent required herein within 30 days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs. c. INFORMATION. Within 20 days after the Indemnified Party receives notice of a claim or legal action that may result in a Loss for which indemnification may be sought under this Article 15 ("CLAIM"), the Indemnified Party shall give written notice of such Claim to the Indemnifying Party. If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with respect to such Claim. At the election of the Indemnifying Party made within 60 days after receipt of such notice, the Indemnified Party shall permit the Indemnifying Party to assume control of such Claim (to the extent only that such Claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party's choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is entitled to be indemnified hereunder without its consent. If the Indemnifying Party elects to assume control, (i) any expense incurred by the Indemnified Party thereafter for investigation or defense of the matter shall be borne by the Indemnified Party, and (ii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter. In the absence of such an election, the Indemnified Party will use its best efforts to defend, at the Indemnifying Party's expense, any claim, legal action or other matter to which such other party's indemnification under this Article 15 applies until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to assume such defense within the time period provided above, settle the same in the Indemnified Party's reasonable discretion at the Indemnifying Party's expense. If such a Claim requires immediate action, both the Indemnified Party and the Indemnifying Party will cooperate in good faith to take appropriate action so as not to jeopardize defense of such Claim or either party's position with respect to such Claim. d. DISPUTE. Other than with respect to a Claim based on an issue for which another method of dispute resolution is provided in this Agreement, if the existence of a valid Claim or amount to be paid by an Indemnifying Party is in dispute, the parties agree to submit determination of the existence of a valid Claim or the amount to be paid pursuant to the Claim Notice to binding arbitration in Colorado, such arbitration to be conducted as follows: The arbitration proceeding shall be governed by Colorado law and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA"), with discovery to be conducted in accordance with the Federal Rules of Civil Procedure, and with any disputes over the scope of discovery to be determined by the arbitrators. The arbitration shall be before a three person panel of neutral arbitrators, consisting of one person from each of the following categories: (1) an attorney who has practiced in the area of oil and gas law for at least ten years; (2) a retired judge at the Colorado or United States District Court or Appellate Court level; and (3) a person with at least ten years of oil and gas industry experience as a petroleum engineer. The AAA shall -32- submit a list of persons meeting the criteria outlined above for each category of arbitrator, and the parties shall select one person from each category in the manner established by the AAA. If the parties cannot agree, AAA shall select the arbitrator(s) on which the parties cannot agree. The arbitrators will have not authority to award punitive damages or any other damages not measured by the prevailing party's actual damages, and may not, in any event, make any ruling, finding or award that does not conform to the terms and conditions of the Agreement. The arbitrators shall conduct a hearing no later than 30 days after submission of the matter to arbitration. At the hearing, the parties shall present such evidence and witnesses as they may choose, with or without counsel. Adherence to formal rules of evidence shall not be required but the arbitration panel shall consider any evidence and testimony that it determines to be relevant, in accordance with procedures that it determines to be appropriate. Any award entered in the arbitration shall be made in writing and any payment due pursuant to the arbitration shall be made within 15 days of the arbitrators' award. The award of the arbitrators need not be accompanied by a reasoned opinion. The arbitrator shall award to the prevailing party, if any, as determined by the arbitrator, all of its costs and fees. "Costs and fees" means all reasonable pre-award expenses of an arbitration, including the arbitrators' fees, administrative fees, travel expenses, out-of- pocket expenses such as copying, telephone, court costs, witness fees, and attorneys fees. The award may be filed in a court of competent jurisdiction and may be enforced by any party as a final judgment of such court. 15.5 NO INSURANCE; SUBROGATION. The indemnifications provided in this Article 15 shall not be construed as a form of insurance. Buyer and Seller hereby waive for themselves, their successors or assigns, including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Buyer and Seller shall obtain waiver of such subrogation from their respective insurers. 15.6 RESERVATION AS TO NON-PARTIES. Nothing herein is intended to limit or otherwise waive any recourse Buyer or Seller may have against any non-party for any obligations or liabilities that may be incurred with respect to the Assets.

Any party may, by written notice so delivered to the other parties, change the address or individual to which delivery shall thereafter be made. 16.4 AMENDMENTS. Except for waivers specifically provided for in this Agreement, this Agreement may not be amended nor any rights hereunder waived except by an instrument in writing signed by the party to be charged with such amendment or waiver and delivered by such party to the party claiming the benefit of such amendment or waiver. 16.5 ASSIGNMENT. Prior to Closing, neither Seller nor Buyer shall assign all or any portion of its respective rights or delegate all or any portion of its respective duties hereunder without the prior written consent of the other party; provided, however, Seller reserves the right to exchange the Assets for property of like kind and qualifying use within the meaning of Section 1031 of the Internal Revenue Code of 1986 and the regulations promulgated thereunder. Seller expressly reserves the right to assign its rights, but not its obligations, hereunder to a "qualified intermediary" as provided in Section 1.103(k)-1(g)(4) of the U.S. Treasury Regulations on or before the Closing Date. Buyer agrees to take all actions reasonably required of it, including, but not limited to, executing and delivering documents, to permit Seller to effect the exchange described in this Section. 16.6 RESERVATION OF RIGHT TO QUALIFY UNDER SECTION 29 OF THE CODE. Seller hereby retains, and Buyer consents thereto, the right to seek qualification of certain of the Assets under Section 29 of the Internal Revenue Code of 1986, as amended, as gas produced from coal seams under Section 503 of the Natural Gas Policy Act of 1978 (and including any successor or similar state or federal legislation) before the Federal Energy Regulatory Commission, or its successor agency. This reservation is not intended to reserve any rights to claim Section 29 credits with respect -34- to production occurring after the Effective Time, but rather is to assure Seller's right to such credits prior to the Effective Time. Buyer agrees to cooperate fully with Seller and to permit access to Buyer's records at all reasonable times to permit Seller to complete this qualification process. 16.7 HART-SCOTT-RODINO ACT. Seller and Buyer agree that no Hart-Scott-Rodino Act filing is necessary with respect to the transaction contemplated by this Agreement. 16.8 ANNOUNCEMENTS. Buyer and Seller agree that prior to making any press releases and other public announcements concerning this Agreement and the transaction contemplated thereby, the party desiring to make such public announcement shall consult with the other party and exercise its best efforts to agree upon the text of any public announcement to be made solely by Buyer or Seller. Seller agrees that the inclusion in Buyer's public announcement of the Purchase Price and estimated reserves attributable to the Assets is not objectionable. 16.9 HEADINGS. The headings of the Articles and Sections of this Agreement are for guidance and convenience of reference only and shall not limit or otherwise affect any of the terms or provisions of this Agreement. 16.10 COUNTERPARTS. This Agreement may be executed by Buyer, Seller, and KLT in any number of counterparts, each of which shall be deemed an original instrument, but all of which together shall constitute one and the same instrument. Execution can be evidenced by fax signatures with original signature pages to follow in due course. 16.11 REFERENCES. References made in this Agreement, including use of a pronoun, shall be deemed to include, where applicable, masculine, feminine, singular or plural, individuals, partnerships or corporations.
