(a) The total consideration for the sale and conveyance of the Assets to Buyer is Buyer's payment of One Hundred Forty-One Million Dollars ($U.S.141,000,000.00), as adjusted in Section 3.1(c) below, (the "Purchase Price"). The cash portion of the Purchase Price, together with and subject to such adjustments, if any, as are expressly provided for elsewhere in this Agreement, shall be paid by Buyer to Seller by means of completed Federal Funds transfers to Seller's account in Apache Canyon Gas, L.L.C., routing number 101000695, account number 9870964996 as follows: (i) Thirty-five Million Dollars ($U.S. 35,000,000.00) and (ii) subject to Section 10.4, Shares of Redeemable Preferred Stock of Buyer with a face value of One Hundred Million Dollars ($U.S.100,000,000.00) pursuant to the provisions set out in EXHIBIT I, ("Preferred Stock"). Also at Closing, subject to Section 10.4, and as a credit to the payment of the Purchase Price, Buyer shall deliver to Seller a certificate or certificates, registered in the name of the Seller 7 or its designee, evidencing ownership of shares of common stock of the Buyer aggregating Six Million Dollars ($US6,000,000.00) of Buyer's common stock (the "Evergreen Stock") calculated as provided in (b) below. The $6,000,000.00 in Evergreen Stock, the Preferred Stock, and the $35,000,000.00 cash paid at Closing, together, constitute the "Initial Payment." (b) The amount of Evergreen Stock to be included in the Initial Payment shall be calculated based on a per-share price equal to the average closing price of the Evergreen Stock for the fifteen trading day period ending the day prior to the Closing. The Evergreen Stock, at Closing, shall not be registered and shall be initially restricted. The terms of Seller's holding of such stock shall be subject to the provisions of EXHIBIT J. (c) On December 29, 2000, the parties shall calculate the simple arithmetic average of the settle prices for NYMEX natural gas futures contracts for the months of January, 2001 through December, 2001, as published in the December 27, 2000, edition of THE WALL STREET JOURNAL under the heading "Natural Gas, (NYM) 10,000 MMBtu.; $ per MMBtu's". If such average equals or exceeds $4.465 per MMBtu, then Buyer shall, on or before January 5, 2001, deliver to Seller a certificate or certificates, registered in the name of the Seller or its designee, evidencing ownership of shares of common stock of the Buyer aggregating Four Million Dollars ($US4,000,000.00) of Buyer's common stock (the Adjustment Stock") calculated as provided in the next sentence. The number of shares of Adjustment Stock shall be calculated based on a per-share price equal to the average closing price of the Adjustment Stock for the fifteen trading day period ending the day prior to the date of delivery of the Adjustment Stock to Seller. The Adjustment Stock, when issued, shall not be registered and shall be initially restricted. The terms of Seller's holding of such stock shall be subject, MUTATIS MUTANDIS, to the provisions of EXHIBIT J. (d) Notwithstanding anything set out herein, if, at December 31, 2000, the Redemption of the Preferred Stock as provided in Section 2.4 of the Amendment to State Terms, set forth in Exhibit I hereof (the "Amendment") has not occurred, the Parties shall make the following calculation: Take the sum of the Dividends received pursuant to Section 2.1 of the Amendment (excluding, however, any Dividends received associated with an increase in Dividends over the initially effective dividend amount of $95 per share per annum set forth in Section 2.1) plus the actual proceeds received by the Seller or its assigns pursuant to that certain production payment reserved in that certain conveyance from Seller to Buyer set forth in Exhibit C ("Production Payment") and covering certain Leases and Lands in Las Animas County, Colorado. If such sum does not equal what Seller would have received had it reserved a production payment equal to the "Applicable Percentage", as defined below, of the Hydrocarbons attributable to such Leases and Lands (instead of the 18.64% that it did reserve), assuming that Seller would have been paid at precisely the same average rate per Mcf, that Seller, in fact, received attributable to is Production Payment reserved in Exhibit C, then Buyer shall be obligated to pay a one- time payment ("December Adjustment"), as an adjustment to the Purchase Price, to Seller equal to the difference between what Seller actually received and what it would have received had it reserved only the Applicable Percentage production payment and had not received, and had not been entitled to receive, any dividend hereunder ("Theoretical Production Payment"). In addition, at the time of the Redemption of the last share of Seller's Preferred Stock, Buyer and Seller shall make the calculation, and Buyer shall be obligated to the payment, if such results from that calculation, as an adjustment to the Purchase Price utilizing the formula set out in the preceding sentence, but calculated from December 8 31, 2000 through the date of the Redemption of the last share of Seller's Preferred Stock ("Final Adjustment") Buyer and Seller both recognize that actual proceeds of the Production Payment may not be paid until the second month after the end of the month in which production occurred. Accordingly, upon each payment required in this Section 3.1(d), the Buyer and Seller shall meet and determine, in good faith, their best estimate of what cash payments Seller is likely to receive from the Production Payment, but attributable to the particular time period set out above, after the relevant date and take that sum into consideration in calculating each of the one-time adjustments provided for hereunder. If Buyer and Seller cannot agree, then the average of the actual proceeds received in the three calendar months next preceding the Adjustment (whether the December Adjustment or the Final Adjustment) shall be used for making such estimate. The Final Adjustment shall be made contemporaneously and as a condition of the Redemption; provided, however, nothing herein shall prohibit Buyer from making the Redemption of the last share of Seller's Preferred Stock on or before December 31, 2000, in which case there shall be only on Adjustment. The Buyer and Seller shall meet within 120 days of each Adjustment to make a final determination of the correct amount of each one-time dividend. If, on the other hand, the Production Payment and the Dividends paid actually exceed the Theoretical Production Payment, then Seller shall refund the excess amount to Buyer. The term "Redemption" has the meaning ascribed to it in the Amendment. (e) As used above, the "Applicable Percentage" means: i. Initially 59.47%. The Applicable Percentage will remain 59.47% if the preferential purchase right applicable to the Lorencito properties (as described under the terms of that certain Agreement for Purchase and Sale between Buyer and Seller of even date herewith) is NOT exercised by the holder thereof. ii. If that preferential right is exercised by the holder thereof, then Buyer, within 10 days following the closing on the exercise of that preferential right, shall make a Redemption of $20 million worth of Seller's Preferred Stock, and upon that Redemption, the Applicable Percentage shall be 56.8%. 3.2 PURCHASE PRICE CREDITS. (a) Within 10 days after December 31, 2000, the parties shall exchange information with respect to revenues received from production and other operating sources (excluding interest income), from or attributable to the Assets for periods on or after the Effective Date received by Seller plus $150,000.00 ("Buyer's Credits") and shall calculate all exploration, production, development, operating, overhead, general and administrative and other costs paid or incurred by Seller with respect to the Assets for such period charged under applicable operating agreements or, if no operating agreement is applicable, then under the most recent COPAS Accounting Procedure Joint Operations ("Seller's Credits") excluding all non-cash charges attributable to depletion, depreciation, bad debt losses, lease abandonment, etc.; provided that Seller shall have no obligation to make any payment that would constitute a Seller's Credit after the Effective Time. Only items of revenue, cost and expense attributable to the Assets shall be included in the foregoing calculations. If Seller's Credits exceed Buyer's Credits, the difference shall be due 9 Seller by Buyer. If Buyer's Credits exceed Seller's Credits, the difference shall be due Buyer by Seller. Prior to the end of the ten day period beginning with December 31, 2000, Seller shall furnish Buyer with an estimated accounting showing the amount of Seller's Credits and the amount of Buyer's Credits. The amount of the final credit, as adjusted, shall be paid in cash on final adjustment by the party owing it. If within such time period, the parties are unable to agree as to whether an item of income or expense belongs in the period before or after the Effective Time, or is properly included in Seller's Credits or Buyer's Credits, or as to any other accounting matters, then such item or matter may be submitted for determination to a mutually acceptable accounting firm in accordance with Section 12.2 hereof. Final settlement shall be made within ten (10) business days following agreement by the Buyer and Seller or final determination by said accounting firm (which final determination shall be binding upon Buyer and Seller). (b) Seller and Buyer or representatives of each shall determine the amount of the Hydrocarbons existing in storage tanks, gathering lines, pipelines, gasoline plants, and other facilities as of the Effective Date using the point or points of delivery to Seller's purchasers as a zero reference point. Seller shall receive a credit in the final adjustment of the Purchase Price as provided for in paragraph (a) above equal to an amount calculated by multiplying the volume of such Hydrocarbons by (i) in the case of oil, the posted price in the field, as of the Effective Time (or if none, a mutually agreeable price) or (ii) in the case of gas, the prevailing spot market price net of transportation and basis differential at the location of the Subject Interests, as of the Effective Time 3.3 PURCHASE PRICE ALLOCATIONS. Seller and Buyer mutually agree to allocate the Purchase Price among the Assets as set forth in EXHIBIT B attached hereto. Seller and Buyer agree that said allocation as set forth in EXHIBIT B is the proper allocation of the Purchase Price in accordance with the fair market value of the Assets, and that said allocation of the Purchase Price of the Assets as set forth in EXHIBIT B shall apply for purposes of Sections 755 and 1060 of the Internal Revenue Code of 1986 (as amended and together with any regulations promulgated thereunder, the "Code").

The Subject Interests are subject to a secured loan in favor of BankOne, N.A. Agent, which will be released at or prior to closing. 7.2 BUYER'S TITLE REVIEW. (a) For 45 calendar days after Closing, Buyer may at Buyer's sole cost and expense commence and diligently pursue such examination of title to the Subject Interests as Buyer desires. Seller shall fully cooperate with Buyer and shall make available to Buyer at Seller's offices in Overland Park, Kansas, all documents, records and material in Seller's possession (except to the extent disclosure of same is prohibited pursuant to agreements with third parties) and all assistance reasonably necessary to assist Buyer in determining the validity of Seller's title in and to the Subject Interests. In no event, however, does Seller warrant or represent the sufficiency, completeness or accuracy of such documents, records and materials, and Buyer's reliance thereon shall be at Buyer's sole risk and expense. Immediately upon completion of Buyer's title review of each property, Buyer shall notify Seller of any Title Defects associated with such property in accordance with Section 7.4 below. Buyer will conclude Buyer's title review and give notice to Seller of all asserted Title Defects not later than five (5) days after the send of said 45 day period. To be effective, Buyer's written notice of a Title Defect must include (i) a brief description of the matter constituting the asserted Title Defect and (ii) supporting documents reasonably necessary for Seller (or a title attorney or examiner hired by Seller) to verify the existence of such asserted Title Defect. 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) Upon receipt of the notice set forth under Section 7.2(a) Seller shall have the right, but not the obligation, for 10 calendar days to cure all or any portion of asserted Title Defects, such curative costs to be borne solely by Seller. If Buyer elects to waive or is deemed to have waived any asserted or unasserted Title Defects, such waived or unasserted Title Defects shall be deemed Permitted Encumbrances hereunder. If Seller within the time provided above is unable, elects not, or refuses, to cure such asserted Title Defects, Buyer may, subject to Section 7.4 below, by written notice delivered to Seller not later than two (2) business days after the end of such period, and as Buyer's sole and exclusive remedy and only if the thresholds of Section 12.9 have been met, elect to have Seller refund to Buyer, a portion of the Purchase Price by an amount attributable to the reserves to which title has failed as mutually agreed upon by the parties and based upon the allocations made pursuant to Section 3.3, and Buyer shall reconvey such portion of the Subject Interests to Seller. Failure by Buyer to timely assert a claim for an adjustment to the Purchase Price shall be deemed an election by Buyer to waive such claim and retain the interest covered by the asserted but uncured Title Defect. In the event Buyer and Seller are unable to agree upon the amount of the downward adjustment of the Purchase Price attributable to a Title Defect for the purposes of the foregoing, then the same shall be submitted for determination to a mutually acceptable reservoir engineering firm whose determination shall be final. 15 7.3 TITLE DEFECTS. For the purposes of this Agreement, a portion of the Subject Interests shall be deemed to have a "Title Defect" if any one or more of the following statements is untrue in any material respect with respect to such portion of the Subject Interests as of the Effective Time: (i) Seller has Defensible Title thereto. (ii) All royalties, rentals, Pugh clause payments, shut-in gas payments and other payments due with respect to such portion of the Subject Interests have been properly and timely paid, except for payments held in suspense for title or other reasons which are customary in the industry and which will not result in grounds for cancellation of Seller's rights in such portion of the Subject Interests. (iii) Except as set forth in any of the Exhibits hereto, Seller is not in default under the material terms of any leases, farmout agreements or other contracts or agreements respecting such portion of the Subject Interests which could (1) materially interfere with the operation; value or use thereof, (2) materially prevent Seller from receiving the proceeds of production attributable to Seller's interest therein, or (3) result in cancellation of Seller's interest therein. (iv) There is no lien, charge, encumbrance, defect or objection (other than a Permitted Encumbrance) against, in or to Seller's title thereto or right or interest therein, and no fact or circumstance relative thereto exists of such significance that a reasonable and prudent person engaged in the business of the ownership, development and operation of oil and gas properties with knowledge of all the facts and appreciation of their legal significance would be unwilling to accept and pay for the Subject Interest or portion thereof which is affected thereby. Notwithstanding the foregoing, loss of any Subject Interest or portion thereof following the Effective Time due to (i) any election or decision made by Seller in accordance with Article VIII or (ii) expiration of the primary or secondary term of a lease shall not constitute a Title Defect as long as Seller shall not have breached the provisions of Article VIII. Subject to Section 14.1 below, the failure of any governmental office to approve or consent to any assignment or other conveyance of a Subject Interest filed with such office shall not constitute a Title Defect; provided that such office has not expressly and specifically refused to grant such consent or approval as a result of the existence of a Title Defect. 7.4 TITLE INDEMNIFICATION. Notwithstanding any other provisions of this Article VII, Seller shall have the option to execute and deliver to Buyer a title indemnity whereby Seller shall keep Buyer indemnified from and against any and all liability, loss, costs (including legal costs), suits, judgments, causes of action, claims or damages arising or incurred in connection with any uncured Title Defects, to the extent the same relate to acts, omissions or other matters occurring prior to the Effective Time and only with respect to such uncured Title Defects. The title indemnity shall be limited to the amount determined in accordance with this Article VII with respect to the particular Asset for which the indemnity is given. If Seller provides such a title indemnity, the relevant uncured Title Defects shall be deemed to be cured and removed for the purposes of this Agreement. ARTICLE VIII 16 COVENANTS OF SELLER 8.1 COVENANTS OF SELLER PENDING CLOSING. From and after the date of execution of this Agreement and until the Closing, except as otherwise consented to by Buyer in writing and subject to Section 8.2 below and the terms of the Material Contracts, Seller shall: (a) Subject to Seller's right to obtain Seller's Credits pursuant to Section 3.2, continue to operate the Assets owned by it for the account of Buyer in a manner consistent with past practices; (b) Maintain in full force and effect all policies of insurance covering the Assets now maintained by Seller; (c) Use reasonable efforts to preserve in full force and effect all material leases, operating agreements, easements, rights-of-way, permits, licenses, contracts and other material agreements included in the Incidental Rights which relate to the Assets in which it owns an interest and perform all material obligations of Seller in or under any such agreement relating to such Assets; (d) Not enter into any agreement or arrangement granting any preferential right to purchase any of the Assets or requiring the consent of any person to the transfer and assignment of any of the Assets hereunder, except in connection with the performance by Seller of an obligation or agreement existing on the date hereof or pursuant to this Agreement; (e) Not dedicate, sell, farm out, encumber or dispose of any Assets without Buyer's written consent except (i) sales of oil and gas production in the ordinary course of business and (ii) as to a portion of the Assets that do not, in the aggregate, constitute a material portion of the Assets; and (f) Maintain all material equipment included in the Assets in accordance with customary industry operating practices and procedures.

Notwithstanding the foregoing, Seller shall not be obligated to pay any lease rental or other payment or to elect to participate in any operation if the third party operator of the property involved recommends that such action not be taken.

If an invoice or other evidence of an obligation is received which under the terms of this Article XI is partially the obligation of Seller and partially the obligation of Buyer, then the parties shall consult each other and each shall promptly pay its portion of such obligation to the obligee, provided that if either party hereto shall fail promptly to pay its portion of such obligation to the obligee, the other party hereto shall have the right (but not the obligation) to pay such portion of such obligation, whereupon the defaulting party shall promptly reimburse such other party for the defaulting party's portion so paid, plus interest on said amounts until reimbursed, at the rate applicable under Article III above. 11.5 SELLER OPERATED PROPERTIES.

This reservation is not intended to reserve any rights to claim Section 29 credits with respect to production occurring after the Effective Date, but rather is to assure Seller's right to such credits prior to the Effective Date.

ARTICLE XII SETTLEMENT OF PRORATIONS 12.1 ACCOUNTING.
