EXHIBIT 99.2 [BLUE DOLPHIN EXPLORATION COMPANY LETTERHEAD] May 21, 1999 AMERICAN RESOURCES OFFSHORE, INC. 160 Morgan Street Versailles, KY 40383 Gentlemen: The purpose of this letter (this "Letter of Intent") is to set forth certain non-binding understandings and certain binding agreements between Blue Dolphin Exploration Company ("BDEX"), a Delaware corporation, and American Resources Offshore, Inc. ("ARO"), a Delaware corporation, with respect to the possible acquisition (the "Possible Acquisition") of certain shares of capital stock, and assets of ARO, on the terms set forth below. The following numbered paragraphs of this Letter of Intent (collectively, the "Non-binding Provisions") reflect our mutual understanding of the matters described in them, but BDEX and ARO each acknowledge that the Non-binding Provisions are not intended to create or constitute any legally binding obligation between them and neither BDEX nor ARO shall have any liability to the other with respect to the Non-binding Provisions until a fully integrated, definitive agreement (the "Definitive Agreement"), and other related documents, are prepared, authorized, executed and delivered by and between BDEX and ARO. In this Letter of Intent, ARO and BDEX are sometimes referred to as the "Parties". PART ONE To facilitate the negotiation of a Definitive Agreement, the Parties request that BDEX's counsel prepare an initial draft thereof. The execution of any such Definitive Agreement would be subject to the satisfactory completion of BDEX's ongoing investigation of ARO's business, and would also be subject to approval by the respective Parties' board of directors. Based on the information currently known to BDEX, it is proposed that the Definitive Agreement include the following terms: 1. BASIC TRANSACTION. ARO is authorized to issue 50,000,000 shares of $.00001 par value common stock and 3,000,000 shares of preferred stock, of which 10,420,000 common shares and 230,000 shares of preferred stock are issued and outstanding. ARO will take such action to convert the preferred stock of its officers and directors to common stock, to enable BDEX to have a 75% ownership interest in ARO upon the completion of the transactions contemplated herein (the "Shares"). BDEX shall be entitled to anti-dilutive rights in the event any preferred shares, warrants or options issued by ARO prior to the Closing remain outstanding and have not been cancelled pursuant to Article 3 b. The parties intend that the closing of the proposed transaction will occur on or before September 30, 1999 (the "Closing") with an effective date of January 1, 1999 (the "Effective Date"). ARO shall provide corporate managerial services to BDEX for a period of eighteen (18) months from the date of Closing, for a monthly fee of thirty five thousand dollars ($35,000). 2. PURCHASE-PRICE. Based on the information known to BDEX on the date hereof, the purchase price for (i) the Shares, and (ii) 80% of ARO's interest in the offshore Gulf Coast properties, will be Thirty Three Million Seven Hundred Fifty Thousand Dollars ($33,750,000), less Net Revenues received for American Resources Offshore, Inc. May 21, 1999 Page 2 production from the effective date to the date of Closing, as defined Exhibit "A". It is understood that BDEX shall have no obligations with regard to the acquisition or disposition of the ARO Appalachian properties. 3. OTHER TERMS. At or prior to the Closing: a. ARO shall take all appropriate action to have fully satisfied and been released from all monetary obligations (excluding obligations to ARO's bank and TECO Oil & Gas, Inc. ("TECO"), which are being assigned to BDEX), including but not limited to (i) accounts payable, and joint interest billings, (except for those arising in the ordinary course of business from the effective date until Closing and as to which purchase price adjustments are made), or those incurred with written approval of BDEX, (ii) all employment agreements, and (iii) office lease agreements. b. Existing Management and Board Members shall agree to a voting trust to support the terms and conditions of the transaction contemplated herein and terminate any options or warrants issued to them by ARO. c. ARO shall take all appropriate action to divest itself of all Appalachian assets and dissolve all subsidiaries prior to the Closing. d. Separate assignments in favor of BDEX executed by TECO and ARO's bank of their respective claims, contract rights and security interests as to ARO are to be delivered to BDEX. The Definitive Agreement would provide for BDEX to release the assigned rights at a point sufficiently subsequent to the Closing to enable BDEX to confirm that ARO has complied fully with its representations, warranties and obligations under the Definitive Agreement provided that a material breach has not occurred. e. BDEX agrees that production marketing positions listed in Exhibit "B" entered into by ARO since the Effective Date shall be deemed to be in the ordinary course of business. ARO agrees that any production marketing positions not listed on Exhibit "B" shall not be deemed to be in the ordinary course of business and that BDEX shall have no responsibility whatsoever therefore, and that the settlement costs for such positions shall not be made from the Net Revenues attributable to the period from the Effective Date to the Closing. f. ARO shall notify BDEX of any authority for expenditures ("AFE") received by ARO, and ARO shall attempt to farmout on best terms, failing which it shall not consent to the AFE unless (i) it receives written consent and approval from BDEX, or (ii) ARO's Bank advances the necessary capital to fund the AFE. If BDEX approves the AFE it shall advance the necessary capital to fund the AFE and shall be entitled to a first lien on the assets to secure repayment of this advance. The property which is the subject matter of the AFE shall be deemed to be included as property to be conveyed (as described below), to Fidelity Oil Holdings, Inc. ("Fidelity"), or owned by the surviving entity without any additional compensation. American Resources Offshore, Inc. May 21, 1999 Page 3 g. ARO shall immediately take steps to terminate its joint venture agreements with Houston Energy on terms and conditions agreed to and approved by BDEX. IN CONNECTION WITH THE CLOSING, 80% OF THE OFFSHORE GULF COAST PROPERTIES OF ARO, AS DESCRIBED IN PARAGRAPH 2. (II), WILL BE ASSIGNED TO FIDELITY WITH AN EFFECTIVE DATE OF JANUARY 1, 1999, FOR NO ADDITIONAL CONSIDERATION TO ARO. 4. DEFINITIVE AGREEMENT. ARO will make comprehensive representations and warranties to BDEX, and will provide comprehensive covenants, indemnities and other protections for the benefit of BDEX. If a Definitive Agreement is not executed by June 15, 1999, or the Parties have not extended this Letter of Intent by mutual agreement in writing, this Letter of Intent shall automatically expire as of June 15, 1999, at 5:00 P.M. Central Daylight Time. The consummation of the contemplated transaction by BDEX would be subject to the satisfaction of various conditions, including, but not limited to: a. ARO has no knowledge of any Environmental Liability relating to or arising out of the companies' assets except as disclosed at or prior to the Effective Date. This warranty shall not apply to (a) any liability relating to the (i) plugging and abandonment of wells and (ii) associated site restoration (except to the extent that it involves the removal of Hazardous Substances therefrom); or (b) each individual claim in respect of Environmental Liability of less than $25,000 up to a maximum aggregate of $250,000. b. A limited warranty to the effect that there are no title defects, liens, claims, or encumbrances occurring by, through or under ARO or any of its subsidiaries, or relating to events or actions which occurred prior to Closing, which would have a material adverse effect on the value of the companies' assets, but with full substitution and subrogation of BDEX in and to all representations and warranties of every kind and character heretofore given or made to ARO or its subsidiaries and their predecessors in title by others with respect thereto. c. BDEX will perform standard due diligence to: (i) confirm the oil and gas reserve report information provided to BDEX by ARO, (ii) confirm the accuracy of the title to the properties owned by ARO as represented in said reserve reports, and (iii) determine the financial condition and pending legal matters of ARO. The Definitive Agreement will contain default and remedy provisions typical of a transaction of this type. PART TWO The following paragraphs of this letter (the "Binding Provisions") are the legally binding and enforceable agreements of BDEX and ARO. 1. ACCESS.

Notwithstanding the foregoing, BDEX's exclusive rights shall terminate prior to the end of the ninety day period if during such period ARO receives an unsolicited offer and ARO's Board of Directors determines in good faith, based on the advice of outside counsel, that its failure to accept such an unsolicited offer would constitute a breach of the Board of Directors' fiduciary duty; and b.
