September 23, 2005 CONSENT AND WAIVER Gentlemen: Reference is made to that certain Securities Purchase Agreement dated as of February 22, 2005 among Consolidated Energy, Inc., a Wyoming corporation (the "Company") and the Purchasers (the "Purchasers") named therein, as amended through the date hereof (the "Purchase Agreement"), the 6% Senior Secured Convertible Notes Due 2008 of Consolidated Energy, Inc. in favor of the holders thereof (the "Senior Notes"), and the other Transaction Documents. Capitalized terms, unless otherwise herein defined, shall have the meanings assigned to them in the Purchase Agreement. Cordillera Fund L.P. (the "Bridge Lender") desires to extend credit to the Company pursuant to a Promissory Note dated September 23, 2005 (the "Bridge Note"). In order to induce the Bridge Lender to extend credit to the Company, the Bridge Lender requires the Purchasers to consent to the Company executing the Bridge Note, incurring the indebtedness under the Bridge Note, and entering into and consummating the transactions and issuance of securities referenced in the Bridge Note (collectively, the "Bridge Loan Transactions"). The undersigned hereby consent to the Company entering into the Bridge Loan Transactions, and hereby waive, on the date hereof and until resolution of the Bridge Loan Transactions, the application of any of the provisions of the Transaction Documents that would be operative by virtue of the Bridge Loan Transactions, including, without limitation, those set forth in Section 3.12, Section 3.15(a) and Section 3.15(b) of the Purchase Agreement, Section 3(c)(ii) of each Senior Note, and Section 6 of each Warrant. The undersigned understand that the Bridge Lender is relying on this letter in order to enter into and consummate the Bridge Loan Transactions and would not do so but for the consent and waivers granted hereunder. Any failure by the Company or the Bridge Lender to comply with the terms of the Subordination Agreement dated September 23, 2005, shall be deemed to be an Event of Default under the Senior Notes (as defined in the Senior Notes) and shall entitle the holders of the Senior Notes to all remedies and actions granted by the Purchase Agreement and Senior Notes. It is agreed that no shares included in any registration statement filed in accordance with the Purchase Agreement for the benefit of the Purchasers, shall be allocated to satisfy any rights or claims asserted in connection with the Bridge Note, except those shares added to any registration statement for the purpose of satisfying the Bridge Note. 1 Each of the holders of the Senior Notes further acknowledges and agrees that this letter agreement shall serve as an endorsement to each of the Senior Notes. This letter agreement shall not constitute a waiver of any other provision of the Transaction Documents nor be construed as an agreement by the Purchasers to waive any provisions of the Transaction Documents for any other transaction or for any other purpose. To the extent this letter agreement constitutes an amendment of the Transaction Documents, the parties by their signature hereon consent and agree to such amendment of the Transaction Documents. This letter agreement may be executed in a number of counterparts, all of which taken together shall constitute one and the same instrument.
