ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

(a). On September 9, 2004, Blue Dolphin Energy Company (the "Company") issued a press release announcing that it entered into a Note and Warrant Purchase Agreement (the "Purchase Agreement") on September 8, 2004 with certain accredited investors and directors of the Company for the purchase and sale of promissory notes in an aggregate principal amount of $750,000 (the "Promissory Notes") and 2.8 million warrants (the "Warrants") to purchase shares of the Company's common stock, par value $.01 per share (the "Common Stock"), at a price of $0.003 per Warrant. The sale of the Promissory Notes and the first tranche of 1.25 million Warrants closed on September 8, 2004. The closing of the sale of the second tranche of 1.55 million Warrants is subject to stockholder approval, as well as customary closing conditions. The sale of securities pursuant to the Purchase Agreement was made in reliance on the exemptions from the registration requirements of the Securities Act of 1933, as amended (the "Act"), pursuant to Section 4(2) of the Act and Rule 506 of Regulation D. The securities were sold without any general solicitation by the Company or its representatives, and each investor represented to the Company that it is an "accredited investor" under the Act. Pursuant to the terms of the Purchase Agreement, the Company has also agreed to file a registration statement with the Securities and Exchange Commission ("SEC") to register the resale of shares of Common Stock issuable upon exercise of the Warrants.

The Promissory Notes mature on December 7, 2004, and accrue interest at a rate of 12.0% per annum, of which 4% is payable monthly and 8% is payable at maturity. The Promissory Notes are secured by a second lien on the Company's Blue Dolphin Pipeline System. The maturity date of the Promissory Notes will be extended to September 7, 2005, if the Company's stockholders approve the issuance of the second tranche of Warrants. The Company's obligations under the Promissory Notes upon the occurrence of a "Default," as that term is defined in the Promissory Notes, includes the following:

o the failure of the Company to pay principal or interest when due on the Promissory Notes;

o the failure of the Company to comply with its covenants or agreements in the Purchase Agreement, the Promissory Notes or any other ancillary documents; and

o the failure of the Company to pay when due any debt or obligation that exceeds $50,000.

A "Default" also includes other customary provisions, for example, the Company's involvement in any bankruptcy proceeding, merger or other similar extraordinary transaction.

The Warrants are immediately exercisable, have an exercise price of $0.25 per share and will expire five years after their date of issuance. The Warrants contain standard antidilution provisions, as well as provisions that will result in adjustments to the exercise price of the Warrants if the Company issues shares of Common Stock at a price below $0.25, subject to certain exceptions.


The Company expects to use the proceeds from this offering for working capital and general corporate purposes. Without this financing, the Company expected to exhaust its cash and working capital during the fourth quarter 2004. The Company now believes that the proceeds from this offering will satisfy its working capital requirements through the first quarter 2005. However, the Company will still need to obtain additional capital to satisfy its cash and working capital requirements past the first quarter 2005. Additionally, in August 2004 the Company was able to restructure existing indebtedness to Tetra Applied Technologies, Inc., in the amount of $668,000, that was originally due in September and October 2004, to be payable in twelve monthly installments of $55,667 beginning September 1, 2004, plus interest on the outstanding balance at the rate of six percent per annum.

Pursuant to the terms of the Purchase Agreement, the Company appointed Laurence N. Benz and F. Gardner Parker to its board of directors. Messrs. Benz and Parker each purchased a Promissory Note in the aggregate principal amount of $25,000.00. Mr. Benz purchased 41,667 Warrants in the first tranche and will purchase 41,667 Warrants in the second tranche. Mr. Parker purchased 41,663 Warrants in the first tranche and will purchase 341,665 Warrants in the second tranche. Michael S. Chadwick, an existing director, purchased a Promissory Note in the aggregate principal amount of $12,500.00, 20,883 Warrants in the first tranche, and will purchase 20,834 Warrants in the second tranche. In addition, subject to stockholder approval, Messrs. Benz, Chadwick and Parker will each be granted 100,000 Warrants (the "Director Warrants").

In addition to serving on the Company's board of directors, Mr. Chadwick is also a Senior Vice President and Managing Director of Sanders Morris Harris Group, Inc. ("SMH"), a financial services holding company headquartered in Houston, Texas. The Company paid SMH a $25,000.00 fee in connection with this transaction and has agreed to retain SMH as the Company's financial advisor for future strategic acquisitions and other related services. The Company, through one of its wholly-owned subsidiaries, has also entered into a consulting agreement with Mr. Parker. Mr. Parker's consulting agreement with the Company has a term of up to eighteen months. The Company will pay Mr. Parker a monthly fee of $2,000.00 and a bonus that will accrue at the rate of $3,000.00 per month and be payable upon consummation of a merger or acquisition by the Company.

The Company expects to hold a special meeting of stockholders in the fourth quarter of 2004 to seek stockholder approval for the issuance of the second tranche of Warrants and the Director Warrants, the election of directors, including Messrs. Benz and Parker, and other matters. In connection with this transaction, certain directors and executive officers of the Company and one of the Company's significant stockholders, who combined represent approximately 41% of the issued and outstanding shares of Common Stock, entered into a voting agreement (the "Voting Agreement") with the investors in the placement and have agreed to vote in favor of the issuance of the second tranche of Warrants and the Directors Warrants, and the election of Messrs. Benz and Parker at the special meeting and next annual meeting of stockholders.

The above description of the terms of the Promissory Notes and the Warrants is only a summary. A copy of the form of Promissory Note, the form of Warrant, the Purchase Agreement, the consulting agreement between Blue Dolphin Services Co. and Mr. Parker, the


Voting Agreement among the investors in this transaction, members of the board of directors and certain executive officers of the Company and the press release are being filed as exhibits to this report and are incorporated herein by reference.

On September 8, 2004, immediately prior to the transaction reported in item 1.01 above, the Company sold the common stock of its wholly owned subsidiary American Resources Offshore, Inc. ("ARO") to the Company's Chairman and Chief Executive Officer, Ivar Siem, on behalf of those stockholders of the Company who hold a number of shares of Company common stock above a threshold to be determined by Mr. Siem, provided, however, that such threshold shall be set at a level, which will include at a minimum the 30 largest shareholders on a proportionate basis. ARO has no revenue and no assets, except for federal net operating loss carryforwards. The consideration paid to the Company consisted of $1,000 cash, the assumption of the transaction costs, including incremental costs associated with the reporting and disclosure of this transaction incurred by the Company in its filings with the SEC and any other required filings or announcements, and the assumption of any and all liabilities of ARO.

7. Maximum Rate. Regardless of any provision in this Note or in any Loan Document it is the intention of Borrower and Lender that Lender not (a) contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the principal of this Note any amount in excess of the Maximum Rate or the Maximum Amount or (b) receive any unearned interest, in violation of any applicable law. If any acceleration of the maturity of this Note or any payment under this Note or any other Loan Document produces a rate in excess of the Maximum Rate or if Lender shall for any reason receive any such unearned interest or if any transaction contemplated hereby or by any other Loan Document would otherwise be usurious under applicable law, then (i) the aggregate of all interest under applicable usury laws that is contracted for, charged, taken, reserved, received or applied under this Note, the other Loan Documents, or otherwise shall under no circumstances exceed the Maximum Amount, (ii) neither Borrower nor any other Person shall be obligated to pay the amount of such interest to the extent that it is in excess of the Maximum Amount, (iii) any excess or unearned interest shall be deemed to be and shall be treated as a partial prepayment or repayment of principal and any remaining excess or unearned interest will be refunded to Borrower, and (iv) the provisions of this Note and the Loan Documents shall immediately be deemed reformed, without the necessity of the execution of any new document or instrument, so as to comply with all applicable usury laws. In determining whether interest paid or payable exceeds the Maximum Rate or the Maximum Amount, Lender shall, to the maximum extent permitted under applicable law (w) treat all advances under this Note and the other Loan Documents as a single extension of credit, (x) characterize any non-principal payment as an expense, fee or premium rather than as interest, (y) exclude voluntary prepayments or repayments and their effects, and (z) amortize, prorate, allocate and spread the total amount of interest throughout the entire contemplated term of this Note. However, if the Note is paid in full before the end of its full contemplated term, and if the interest received for its actual period of existence exceeds the Maximum Rate or the Maximum Amount, Lender shall refund any excess (and Lender may not, to the extent permitted by law, be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Amount). If the Laws of the State of Texas are applicable for purposes of determining the "Maximum Rate" or the "Maximum Amount," the "Maximum Rate" may not exceed the "weekly ceiling" from time to time in effect under Chapter 303 of the Texas Finance Code, as amended and in effect from time to time.

8. Conditions to Advance. Lender shall advance to Borrower all of the proceeds under this Note in a single advance upon execution and delivery to Lender of each of the following documents in form and substance satisfactory to Lender (i) this Note, (ii) the Mortgage, (iii) the Note and Warrant Purchase Agreement, (iv) the Warrants, (v) the Voting Agreement, (vi) a letter agreement among Borrower, the Collateral Agent designated in the

9. Representations. Borrower does hereby certify, warrant and represent unto, and agrees with, Lender as follows: (i) the Salvage Contract and Prior Lien Instruments are in good standing and, to the best knowledge and belief of Borrower, no uncured breaches or defaults exist thereunder; (ii) the unpaid unpaid balance of the Salvage Contract on this date is $668,000; (iii) no amount other than the outstanding amount under the Salvage Contract is claimed to be owing or secured by the Prior Line Instruments; and (iv) upon the occurrence of an event of default under the Salvage Contract, the Prior Lien Instruments or any other agreement or instrument secured by any Prior Lien Instrument, Borrower shall provide Collateral Agent with written notice of such default within three
(3) Business Days of knowledge of such default.

10. Negative Covenant. During the term of this Note, without prior consent of the Collateral Agent, Borrower will not allow any material change to be made in the character of its business, nor will it allow any Subsidiary to make any material change to be made in the character of any of their businesses.

11. Default. The term "DEFAULT" means the occurrence of any one or more of the following events:

(A)

5

(f) Any warrant of attachment, sequestration or similar proceeding against Borrower or any Subsidiary's assets is not stayed within 10 days or diligently contested in good faith by appropriate proceedings diligently pursued with adequate reserves being made in accordance with GAAP.

(g) Any representation or warranty made to Lender (or its representatives) by Borrower or such grantor or obligor or contained in any Loan Document, at any time proves to have been incorrect, incomplete or misleading when made.

(i) Borrower or such Subsidiary breaches or defaults under any term, condition, provision, representation or warranty contained in any agreement, including any agreement with Lender (other than this Note and the other Loan Documents), and the effect of such breach or default could reasonably be expected to result in a Material Adverse Effect on the consolidated financial condition of Borrower and Borrower fails for 5 Business Days to commence and thereafter diligently pursue a cure.

Borrower shall promptly pay upon demand (a) all reasonable costs, fees and expenses paid or incurred by Lender in connection with the negotiation, preparation, delivery and execution of this Note and the Loan Documents, including those incurred in connection with the preparation, execution and delivery of collateral documents, and any related or subsequent amendment, waiver or consent (including in each case, the reasonable fees and expenses of Lender's counsel), (b) all due diligence, closing, and post-closing costs including filing fees, recording costs, lien searches, corporate due diligence, third-party expenses, appraisals (if required by Lender), title insurance (if required by Lender), environmental surveys (if required by Lender), and other related due diligence, closing and post-closing costs and expenses, and (c) all costs, fees and expenses of Lender incurred in connection with the enforcement of this Note and the Loan Documents or the exercise of any rights arising under the Loan Documents (including reasonable attorneys' fees, expenses and costs paid or incurred in connection with any negotiation, workout or restructure and any action taken in connection with any Debtor Relief Laws), all of which shall be a part of the Obligation and shall accrue interest, if not paid upon demand, at the Default Rate until repaid.

18. Remedies of Lender. Lender shall have all rights, remedies, and recourse granted in this Note and all other Loan Documents and those available at law or equity and the same (a) shall be cumulative and concurrent, (b) may be pursued separately, successively, or concurrently against Borrower or any other liable party or against any one or more of them in such order as Lender, in its sole discretion, shall determine, (c) may be exercised as often as occasion therefor shall arise, it being agreed by Borrower and any other liable party that the exercise or failure to exercise any of the same shall in no event be construed as a waiver or release thereof or of any other right, remedy, or recourse, and (d) are intended to be, and shall be, nonexclusive.

19. Subordination. Anything herein or any Loan Document to the contrary, the security interests created under the Mortgage shall be subordinate to the security interests granted by Blue Dolphin Pipeline Company to MCNIC Offshore Pipeline & Processing Company ("MCNIC") in and to the "Collateral" as defined in and pursuant to that certain Pledge and Security Agreement dated February 1, 2002 ("MCNIC SECURITY AGREEMENT"). Should an event of default occur pursuant to the terms of the MCNIC Security Agreement, such act shall constitute an event of default hereunder. In such event and to the extent MCNIC commences any remedial action under the MCNIC Security Agreement, the Collateral Agent on behalf of the Investors may, at its option, cure the default under the MCNIC Security Agreement.

Should the Collateral, as defined in the MCNIC Security Agreement, be sold by virtue of a foreclosure sale (or other sale) authorized pursuant to the terms of the MCNIC Security Agreement, and should such sale be for an amount in excess of the indebtedness secured by the MCNIC Security Agreement, such residue, up to the amount of the indebtedness under the "Notes," as defined in the Mortgage (including any authorized fees and expenses) shall be paid directly by MCNIC to Collateral Agent for the ratable benefit of the Investors.

SECTION 1. EXERCISE OF WARRANTS.

(a) The Warrants may be exercised in whole or in part, at any time or from time to time, during the Exercise Period, by presentation and surrender to the Company at its address set forth in SECTION 8 of this Warrant Certificate (or the delivery of a customary affidavit of loss with indemnity) with the Election To Exercise, attached hereto as EXHIBIT A duly completed and executed, and (i) payment in full of the Exercise Price, for the number of Warrants being exercised by wire transfer in immediately available funds, bank draft or cashier's check, or (ii) without payment of any additional consideration through a "cashless" or "net-issue" exercise of each such Warrant ("Cashless Exercise"); in a Cashless Exercise, the holder shall exchange each Warrant subject to a Cashless Exercise for that number of Warrant Shares determined by multiplying the number of Warrant Shares issuable hereunder by a fraction, the numerator of which shall be the difference between (x) the Price (for the trading day preceding such presentation and surrender), and (y) the Exercise Price for each such Warrant, and the denominator of which shall be the Price (for the trading day preceding such presentation and surrender); and the Election to Exercise shall set forth the calculation upon which the Cashless Exercise is based, or (iii) a combination of (i) and (ii) above. If the holder of this Warrant Certificate at any time exercises less than all the Warrants, the Company shall issue to such a holder a warrant certificate identical in form to this Warrant Certificate, but evidencing a number of Warrants equal to the number of Warrants originally represented by this Warrant Certificate less the number of Warrants previously exercised. Likewise, upon the presentation and surrender of this Warrant Certificate to the Company at its address set forth in SECTION 8 and at the request of the holder, the Company will, without expense, at the option of the holder, issue to the holder in substitution for this Warrant Certificate one or more warrant certificates in identical form and for an aggregate number of Warrants equal to the number of Warrants evidenced by this Warrant Certificate.

2

(b) To the extent that the Warrants have not been exercised at or prior to the Expiration Date, such Warrants shall expire and the rights of the holder shall become void and of no effect.

(c) Upon surrender of this Warrant Certificate in conformity with the foregoing provisions, the Company shall transfer to the holder of this Warrant Certificate appropriate evidence of ownership of the shares of Common Stock or other securities or property (including any money) to which the holder is entitled, registered or otherwise placed in, or payable to the order of, the name or names of the holder or such transferee as may be directed in writing by the holder, and shall deliver such evidence of ownership and any other securities or property (including any money) to the Person or Persons entitled to receive the same, together with an amount in cash in lieu of any fraction of a share.

(d) The Company shall not be required to issue a fractional share of Common Stock upon the exercise of Warrants. As to any fraction of a share which the Warrant holder would otherwise be entitled to purchase upon such exercise, the Company may pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Price per share of Common Stock on the date of exercise.

SECTION 2. ANTIDILUTION ADJUSTMENTS. The shares of Common Stock purchasable on exercise of the Warrants are shares of Common Stock as constituted as of the Issuance Date. The number and kind of securities purchasable upon the exercise of the Warrants, and the Exercise Price, shall be subject to adjustment from time to time upon the happening of certain events, as follows:

(a) Mergers, Consolidations and Reclassifications. In case of any reclassification or change of outstanding securities issuable upon exercise of the Warrants at any time after the Issuance Date (other than a change in par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination to which
SECTION 2(b) applies), or in case of any consolidation or merger of the Company with or into any entity or other person (other than a merger with another entity or other person in which the Company is the surviving corporation and which does not result in any reclassification or change in the securities issuable upon exercise of this Warrant Certificate), the holder of the Warrants shall have, and the Company, or such successor corporation or other entity, shall covenant in the constituent documents effecting any of the foregoing transactions that such holder does have the right to obtain, upon the exercise of the Warrants, in lieu of each share of Common Stock, other securities, money or other property theretofore issuable upon exercise of a Warrant, the kind and amount of shares of stock, other securities, money or other property receivable upon such reclassification, change, consolidation or merger by a holder of the shares of Common Stock, other securities, money or other property issuable upon exercise of a Warrant if the Warrants had been exercised immediately prior to such reclassification, change, consolidation or merger. The constituent documents effecting any such reclassification, change, consolidation or merger shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided in this

3

SECTION 2(a). The provisions of this SECTION 2(a) shall similarly apply to successive reclassifications, changes, consolidations or mergers.

(b) Subdivisions and Combinations. If the Company, at any time after the Issuance Date, shall subdivide its shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision shall be proportionately reduced, and the number of shares of Common Stock purchasable upon exercise of the Warrants shall be proportionately increased, as at the effective date of such subdivision, or if the Company shall take a record of holders of its Common Stock for such purpose, as at such record date, whichever is earlier. If the Company, at any time after the Issuance Date, shall combine its shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased, and the number of shares of Common Stock purchasable upon exercise of the Warrants shall be proportionately reduced, as at the effective date of such combination, or if the Company shall take a record of holders of its Common Stock for purposes of such combination, as at such record date, whichever is earlier.

(c) Dividends and Distributions. If the Company at any time after the Issuance Date shall declare a dividend on its Common Stock payable in stock or other securities of the Company to the holders of its Common Stock, the holder of this Warrant Certificate shall, without additional cost, be entitled to receive upon any exercise of a Warrant, in addition to the Common Stock to which such holder would otherwise be entitled upon such exercise, the number of shares of stock or other securities which such holder would have been entitled to receive if he had been a holder immediately prior to the record date for such dividend (or, if no record date shall have been established, the payment date for such dividend) of the number of shares of Common Stock purchasable on exercise of such Warrant immediately prior to such record date or payment date, as the case may be.

(d) Adjustments of Exercise Price. This SECTION 2(d) shall govern adjustments to the Exercise Price for the transactions described herein.

(i) If (x) the Company at any time after the Issuance Date and prior to the expiration of eighteen months after the Issuance Date shall issue any additional shares of Common Stock (otherwise than as provided in subsections (a) through (c) of SECTION 2; pursuant to any Employee Benefit Plan (defined below); or pursuant to any security or evidence of indebtedness which is convertible into or exchangeable for Common Stock ("CONVERTIBLE SECURITY") or any warrant, option or other right to subscribe for or purchase common stock or any Convertible Security, other than pursuant to Employee Benefit Plans, (together with Convertible Securities hereinafter referred to as "COMMON STOCK EQUIVALENT") outstanding as of the Issuance Date) or upon the issuance of any such Common Stock, any adjustments shall previously have been made pursuant to SECTION
2(d)(ii), and (y) the New Stock Issuance Price (defined below) of such additional shares is less than the Exercise Price then in effect, then the Exercise Price upon each such issuance shall be adjusted to the New Stock Issuance Price of such additional shares. The "New Stock Issuance Price" shall be determined by

4

dividing the total amount of consideration received by the Company for such issue or sale by the number of shares of Common Stock issued or sold.

(ii) If the Company at any time after the Issuance Date and prior to the expiration of eighteen months after the Issuance Date, issues any Common Stock Equivalent (otherwise than as provided in subsections (a) through (c) of SECTION 2; or pursuant to any Common Stock Equivalent outstanding as of the Issuance Date) and the New CSE Exercise Price (defined below) of such Common Stock Equivalents is less than the Exercise Price then in effect, then the Exercise Price upon each such issuance shall be adjusted to the New CSE Exercise Price of such Common Stock Equivalents. The "New CSE Exercise Price" shall be determined by dividing (x) the total amount, if any, received or receivable by the Company as consideration for the issuance of such Common Stock Equivalents, plus the minimum aggregate amount of additional consideration payable to the Company upon the exercise, conversion or exchange of such Common Stock Equivalents, plus, in the case of any such Common Stock Equivalents which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange of such Convertible Securities, by (y) the total maximum number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Common Stock Equivalents.

No adjustments of the Exercise Price shall be made under this SECTION 2(d) upon the issuance of any additional shares of Common Stock that (w) are issued pursuant to any grant or award made prior to the Issuance Date under any thrift plan, stock purchase plan, stock bonus plan, stock option plan, employee stock ownership plan, incentive or profit sharing arrangement or other benefit or compensation plan for the benefit of the Company's officers, directors and/or employees ("EMPLOYEE BENEFIT PLANS") that has been approved by the Board of Directors of the Company or its compensation committee and that otherwise would cause an adjustment under this SECTION 2(d); (x) are issued pursuant to any grant or award made on or after the Issuance Date under any Employee Benefit Plan if the "Exercise Price" of any such issuance is not less than the lesser of the Exercise Price as determined above and the "Fair Market Value," as defined under the applicable Employee Benefit Plan, on the date of Board or compensation committee authorization; (y) are issued pursuant to any Common Stock Equivalent (as hereinafter defined) if such Common Stock Equivalent was issued prior to this Warrant Certificate; or (z) are issued pursuant to a public offering by the Company.

(e) Miscellaneous. The following provisions shall be applicable to the making of adjustments in the Exercise Price hereinbefore provided in this SECTION 2.

(i) The consideration received by the Company shall be deemed to be the following: (x) to the extent that any additional shares of Common Stock or any Common Stock Equivalent shall be issued for cash consideration, the consideration received by the Company therefor, or, if such additional shares of Common

5

Stock or Common Stock Equivalent are offered by the Company for subscription, the subscription price, or, if such additional shares of Common Stock or Common Stock Equivalent are sold to underwriters or dealers for public offering without a subscription offering, the public offering price, in any such case excluding any amounts paid or receivable for accrued interest or accrued dividends and without deduction of any compensation, discounts, commissions or expenses paid or incurred by the Company for and in the underwriting of, or otherwise in connection with, the issue thereof; and (y) to the extent that such issuance shall be for a consideration other than cash, then, except as herein otherwise expressly provided, the fair value of such consideration at the time of such issuance as determined in good faith by the Board of Directors, as evidenced by a certified resolution of the Board of Directors delivered to the holder of this Warrant Certificate setting forth such determination. The consideration for any additional shares of Common Stock issuable pursuant to any Common Stock Equivalent shall be the consideration received by the Company for issuing such Common Stock Equivalent, plus the additional consideration payable to the Company upon the exercise, conversion or exchange of such Common Stock Equivalent. In case of the issuance at any time of any additional shares of Common Stock or Common Stock Equivalent in payment or satisfaction of any dividend upon any class of stock other than Common Stock, the Company shall be deemed to have received for such additional shares of Common Stock or Common Stock Equivalent (which shall not be deemed to be a dividend payable in, or other distribution of, Common Stock under SECTION 2(c)consideration equal to the amount of such dividend so paid or satisfied. In the event additional shares of Common Stock or Common Stock Equivalents are issued together with other shares or securities or other assets of the Company or its subsidiaries for consideration which covers both, the consideration for such shares of Common Stock and Common Stock Equivalents shall be computed based on the respective portions of such consideration so received, computed as provided in this SECTION 2(e)(i) as determined and allocated in good faith by the Board of Directors of the Company.

(ii) Upon the expiration of the right to convert, exchange or exercise any Common Stock Equivalent the issuance of which effected an adjustment in the Exercise Price, if any such Common Stock Equivalent shall not have been converted, exercised or exchanged, the number of shares of Common Stock deemed to be issued and outstanding because they were issuable upon conversion, exchange or exercise of any such Common Stock Equivalent shall no longer be computed as set forth above, and the Exercise Price shall forthwith be readjusted and thereafter be the price which it would have been (but reflecting any other adjustments in the Exercise Price made pursuant to the provisions of SECTION 2(d) after the issuance of such Common Stock Equivalent) had the adjustment of the Exercise Price made upon the issuance or sale of such Common Stock Equivalent been made on the basis of the issuance only of the number of additional shares of Common Stock actually issued upon exercise, conversion or exchange of such Common Stock Equivalent and thereupon only the number of additional shares of Common Stock actually so issued shall be deemed to have been issued and only the consideration actually received by the Company (computed as in this
SECTION 2(e)(i)) shall be deemed to have been received by the Company.

6

(iii) The number of shares of Common Stock at any time outstanding shall not include any shares thereof then directly or indirectly owned or held by or for the account of the Company or its wholly owned subsidiaries.

(iv) Upon each adjustment of the Exercise Price as a result of the calculations made in SECTION 2(d), hereof, this Warrant shall thereafter evidence the right to purchase, at the adjusted Exercise Price, the number of shares of Common Stock obtained by (x) multiplying the number of shares covered by this Warrant immediately prior to such adjustment of the number of shares by the Exercise Price in effect immediately prior to such adjustment of the Exercise Price, and (y) dividing the product so obtained by the Exercise Price in effect immediately after such adjustment of the Exercise Price.

(v) For the purpose of this SECTION 2 the term "shares of Common Stock" shall mean shares of (x) the class of stock designated as the Common Stock at the date hereof, or (y) any other class of stock resulting from successive changes or reclassifications of such shares consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. If at any time, because of an adjustment pursuant to SECTION 2(a), the Warrants shall entitle the holders to purchase any securities other than shares of Common Stock, thereafter the number of such other securities so purchasable upon exercise of each Warrant and the Exercise Price of such securities shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in this SECTION 2.

(f) Calculation of Exercise Price. The Exercise Price in effect from time to time shall be calculated to four decimal places and rounded to the nearest thousandth.

(g) NASDAQ Matters. Notwithstanding anything to the contrary herein, any adjustment to the Exercise Price that would require stockholder approval pursuant to the NASDAQ Market Rules shall be subject to the Company's obtaining such requisite approval.

SECTION 3. NOTICE OF ADJUSTMENTS. Whenever the Exercise Price or the number of shares of Common Stock is required to be adjusted as provided in
SECTION 2, the Company shall forthwith compute the adjusted Exercise Price or the number of shares of Common Stock issuable and shall prepare and mail to the holder hereof a certificate setting forth such adjusted Exercise Price or such number of shares of Common Stock, showing in reasonable detail the facts upon which the adjustment is based.

SECTION 4. NOTICES TO WARRANT HOLDERS. In the event:

(a) the Company authorizes any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or the conveyance or sale of all or substantially all of the assets of the Company, or any reclassification or change of the Common Stock or other securities

7

issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value or as result of a subdivision or combination), or a tender offer or exchange offer for shares of Common Stock (or other securities issuable upon the exercise of the Warrants); or

(b) the Company declares any dividend (or any other distribution) on the Common Stock or any other class of its capital stock; or

(c) the Company authorizes the granting to the holders of Common Stock or any other class of its capital stock of rights or warrants to subscribe for or purchase any shares of any class or series of capital stock or any other securities convertible into or exchangeable for shares of stock; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; then the Company shall cause to be sent to the holder hereof, at least 30 days prior to the applicable record date hereinafter specified, or promptly in the case of events for which there is no record date, a written notice stating (x) the date for the determination of the holders of record of shares of Common Stock (or other securities issuable upon the exercise of the Warrants) entitled to receive any such dividends or other distribution, (y) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock
(or other securities issuable upon the exercise of the Warrants), or (z) the date on which any of the events specified in subsections (a)-(d) is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock (or other securities issuable upon the exercise of the Warrants) shall be entitled to exchange such shares for securities or other property, if any, deliverable upon any such event. Failure to give such notice or any defect therein shall not affect the legality or validity of any such event, or the vote upon any such action.

SECTION 5. REPORTS TO WARRANT HOLDERS. The Company will cause to be delivered, by first-class mail, postage prepaid, to holder at such holder's address appearing hereon, or such other address as the holder shall specify, a copy of any reports delivered by the Company to the holders of Common Stock.

SECTION 6. COVENANTS OF THE COMPANY. The Company covenants and agrees that:

(a) Until the Expiration Date, the Company shall at all times reserve and keep available, out of the aggregate of its authorized but unissued Common Stock (and other securities), for the purpose of enabling it to satisfy any obligation to issue shares of Common Stock (and other securities) upon the exercise of the Warrants, the number of shares of Common Stock (and other securities) issuable upon the exercise of such Warrants.

(b) The Company shall pay all expenses, taxes and other charges payable in connection with the preparation, issuance and delivery of new warrant certificates on transfer of the Warrants.

8

(c) All Common Stock (and other securities) which may be issued upon exercise of the Warrants shall upon issuance be validly issued, fully paid, non-assessable and free from all preemptive rights and all taxes, liens and charges with respect to the issuance thereof, and will not be subject to any restrictions on voting or transfer thereof except as set forth in the Note and Warrant Purchase Agreement, any stockholders agreement and except for restrictions arising under state or federal securities laws.

(d) All original issue taxes payable in respect of the issuance of shares of Common Stock to the registered holder hereof upon the exercise of the Warrants shall be borne by the Company; provided, however, that the Company shall not be required to pay any tax or charge imposed in connection with any transfer involved in the issuance of any certificates representing shares of Common Stock (and other securities) in any name other than that of the registered holder hereof, and in such case the Company shall not be required to issue or deliver any certificate representing shares of Common Stock (and other securities) until such tax or other charge has been paid or it has been established to the Company's satisfaction that no such tax or charge is due.

(e) As soon as practicable after the receipt from the holder of this Warrant Certificate of notice of the intent to exercise of a number of warrants sufficient to require a filing under the Hart Scott-Rodino Antitrust Improvements Act of 1976 and the rules, regulations and formal interpretations thereunder, as amended from time to time (the "HSR ACT") (and after the receipt, if applicable, of the notice referred to in Rule 803.5 of the HSR Act), but in any event no later than the 15 Business Days after receipt of such notice(s), the Company will (i) if required by the HSR Act, prepare and file with Antitrust Division of the Department of Justice (the "DOJ") and the Federal Trade Commission (the "FTC") the Notification and Report Form (accompanied by all documentary attachments contemplated thereby) required by the HSR ACT, (ii) upon request of the holder, request early termination of the waiting period imposed by the HSR Act, and (iii) coordinate and cooperate with the holder in responding to formal and informal requests for additional information and documentary material from the DOJ and the FTC in connection with such filing. Notwithstanding the foregoing, if the holder is required to file with the DOJ and FTC the Notification and Report Form solely as a result of its holding and/or purchasing shares of Common Stock issued pursuant to this Warrant (with no regard to any other securities held by such holder or its affiliates) and the holder certifies such fact to the Company in writing, the Company agrees to promptly reimburse the holder for all fees and expenses for the preparation and filing of such form, including all legal expenses and filing fees.

(f) The Company will not change the par value of the Common Stock from par value $0.01 per share to any higher par value which exceeds the Exercise Price then in effect, and will reduce the par value of the Common Stock upon any event described in SECTION 2 that would, but for this provision, reduce the Exercise Price below the par value of the Common Stock.

SECTION 7. NO RIGHTS AS STOCKHOLDER. The holder of the Warrants shall not, by virtue of holding such Warrants, be entitled to any rights of a stockholder of the Company either

9

at law or in equity, and the rights of the holder of the Warrants are limited to those expressed herein.

ARTICLE III.
REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to the Investors, as of the date hereof, that:

3.1 Corporate Organization. The Company is a corporation duly incorporated, validly existing, and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to own, lease, and operate its properties and to carry on its business in all material respects as now being conducted. No actions or proceedings to dissolve the Company are pending or, to the best knowledge of the Company, threatened. The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is necessary, except where the failure to so qualify or to be in good standing would not reasonably be expected to have a Material Adverse Effect on the Company.

3.2 Capitalization of the Company.

(a) As of the date hereof, the authorized capital stock of the Company consists of 10,000,000 shares of Common Stock and 2,500,000 shares of preferred stock, $0.10 par value, 210,526 of which are designated as Series A Preferred Stock.

(b) Except as set forth above in subparagraph (a) of this Section 3.2, there are outstanding (i) no shares of capital stock or other voting securities of the Company; (ii) no securities of the Company convertible into or exchangeable for shares of capital stock or other voting securities of the Company; (iii) no options or other rights to acquire from the Company, and no obligation of the Company to issue or sell, any shares of capital stock or other voting securities of the Company or any securities of the Company convertible into or exchangeable for such capital stock or voting securities; and (iv) no equity equivalents, interests in the ownership or earnings, or other similar rights of or with respect to the Company.

(c) Neither the execution of this Agreement nor the performance of the Company's obligations hereunder, nor the consummation of any other transaction currently contemplated by the Company or any of its Subsidiaries, will trigger or cause any adjustment under any anti-dilution provisions or any other similar provisions contained in any agreement as currently in effect that have the effect of (i) causing a decrease in any exercise price or conversion price in any security exercisable for or convertible into shares of Common Stock (a "Common Stock Equivalent"), or (ii) causing an increase in the number of shares of Common Stock that may be acquired upon conversion or exercise of a Common Stock Equivalent.

3.3 Authority Relative to This Agreement. Subject to the Company obtaining the Stockholder Approval required by the rules, regulations and interpretations of the Nasdaq Stock Market, Inc. with respect to the issuance of the Additional Warrants, the Company has requisite corporate power and authority to execute, deliver, and perform this Agreement and to execute, deliver, and where applicable, perform the Ancillary Documents to which it is a party and to consummate the transactions contemplated hereby and thereby.

("Nasdaq") with respect to the issuance of the Additional Warrants, the execution, delivery and performance by the Company of this Agreement and the execution, delivery, and where applicable, performance by it of the Ancillary Documents to which it is a party, and the consummation by it of the transactions contemplated hereby and thereby, have been (or prior to the Closing will have been) duly authorized by all necessary corporate action of the Company. Notwithstanding the foregoing, the Company has requisite corporate power and authority to perform the Company's obligations pursuant to Article V, and such performance has been duly authorized by all necessary corporate action of the Company. This Agreement has been duly executed and delivered by the Company and constitutes, and each Ancillary Document executed or to be executed by the Company has been, or when executed will be, duly executed and delivered by the Company and constitutes, or when executed and delivered will constitute, a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except that such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, and similar laws affecting creditors' rights generally, and (ii) general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

3

3.4 Noncontravention. The execution, delivery, and performance by the Company of this Agreement and the execution, delivery, and where applicable, the performance by it of Ancillary Documents to which it is a party and the consummation by it of the transactions contemplated hereby and thereby do not and will not (i) conflict with or result in a violation of any provision of the Company's Certificate of Incorporation, as amended, or the Company's Bylaws, as amended, or the charter, bylaws or other governing instruments of any Subsidiary, (ii) conflict with or result in a violation of any provision of, or constitute (with or without the giving of notice or the passage of time or both) a default under, or give rise (with or without the giving of notice or the passage of time or both) to any loss of material benefit, or of any right of termination, cancellation, or acceleration under, any Material Agreement, (iii) result in the creation or imposition of any Encumbrance upon the properties of the Company or any Subsidiary or (iv) assuming compliance with the matters referred to in Section 3.5, violate any Applicable Law binding upon the Company or any Subsidiary, except, in the case of clauses (ii), (iii) and (iv) above, for any such conflicts, violations, defaults, terminations, cancellations, accelerations, or Encumbrances which would not, or would not reasonably be likely to, individually or in the aggregate, have a Material Adverse Effect on the Company.

3.5 Consents and Approvals. No consent, approval, order, or authorization of, or declaration, filing, or registration with, any Governmental Entity is required to be obtained or made by the Company or any Subsidiary in connection with the execution, delivery, or performance by the Company of this Agreement and the execution, delivery, and where applicable, performance of Ancillary Documents to which it is a party or the consummation of the transactions contemplated hereby and thereby, other than (i) compliance with any applicable requirements of the Securities Act, (ii) compliance with any applicable requirements of the Exchange Act, (iii) compliance with any applicable state securities laws; (iv) compliance with any applicable rules, regulations, interpretations or other requirements of Nasdaq; (v) compliance with any applicable requirements of the HSR Act as a result of the exercise of any of the Warrants, and (vi) with respect to the Additional Warrants, filing of the Amended and Restated Certificate of Incorporation.

3.6 Authorization of Issuance; Reservation of Shares. The issuance, sale and delivery of the Notes and the Warrants in accordance with this Agreement, and the issuance and delivery of the Warrant Shares upon exercise of the Warrants, have been duly authorized by all necessary corporate action on the part of the Company. Subject to the Company obtaining the Stockholder Approval, the Warrant Shares issuable upon exercise of an Additional Warrant have been duly and validly reserved and, when issued upon exercise of an Additional Warrant, will be duly and validly issued, fully paid and nonassessable. The issuances of the Warrants are not subject to any preemptive or similar rights.

4

3.7 Financial Condition. Each of the consolidated balance sheets included in or incorporated by reference into the Company Reports (including the related notes and schedules) fairly presents in all material respects the consolidated financial position of the Company and its Subsidiaries as of its date, and each of the consolidated statements of income, cash flows and changes in shareholders' equity included in or incorporated by reference into the Company Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, stockholders' equity, and cash flow of the Company for the periods set forth therein (subject, in the case of unaudited statements, to (x) such exceptions as may be permitted by Form 10-QSB and Regulation S-B of the SEC and (y) normal year end audit adjustments), in each case in accordance with generally accepted accounting principles consistently applied during the periods involved, except as may be noted therein. Except as and to the extent set forth on the most recent consolidated balance sheet of the Company and its Subsidiaries included in the Company Reports, including all notes thereto, as of the date of such balance sheet, neither the Company nor any of its Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) that would be required to be reflected on, or reserved against in, a balance sheet of the Company or in the notes thereto prepared in accordance with generally accepted accounting principles consistently applied, other than liabilities or obligations which do not and are not reasonably likely to have, individually or in the aggregate, a Material Adverse Effect on the Company. Since June 30, 2004, there has been no change or event having or reasonably likely to have a Material Adverse Effect on the Company, except as set forth in the Disclosure Letter delivered by the Company to the Investors contemporaneously with the execution and delivery of this Agreement (the "Disclosure Letter").

3.8 Litigation. Except as disclosed in the Company's annual report on Form 10-KSB for the fiscal year ended December 31, 2003, or quarterly reports on Form 10-QSB for the quarters ended March 31, 2004 and June 30, 2004, filed with the SEC (collectively, the "Company Reports") or as set forth in the Disclosure Letter, as of the date hereof there is no Proceeding or other action of any nature pending or, to the knowledge of the Company, threatened against or affecting the Company or any Subsidiary which may reasonably have a Material Adverse Effect on the Company.

3.9 ERISA.

(a) The Company and each ERISA Affiliate have complied in all material respects with ERISA and, where applicable, the Code regarding each Plan. Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code.

(b) No act, omission or transaction has occurred which could result in imposition on the Company or any ERISA Affiliate (whether directly or indirectly) of an amount of $10,000 or more as (i) either a civil penalty assessed pursuant to section 502(c), (i) or (1) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under section 409 of ERISA.

(c) No Plan that is subject to Title IV of ERISA or any trust created under any such Plan has been terminated since September 2, 1974. No liability to the Pension Benefit Guaranty Corporation in excess of $10,000 (other than for the payment of current premiums which are not

5

past due) by the Company or any ERISA Affiliate has been or is expected by the Company or any ERISA Affiliate to be incurred with respect to any Plan.

(d) Full payment when due has been made of all amounts which the Company or any ERISA Affiliate is required under the terms of each Plan or applicable law to have paid as contributions to such Plan, and no accumulated funding deficiency in an amount of $10,000 or more (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to any Plan.

(e) The actuarial present value of the benefit liabilities under each Plan which is subject to Title IV of ERISA does not, as of the end of the Company's most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities by $10,000 or more. The term "actuarial present value of the benefit liabilities" shall have the meaning specified in section 4041 of ERISA.

(f) None of the Company or any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by the Company or any ERISA Affiliate in its sole discretion at any time without any material liability (other than run off liability in the ordinary course of payment of benefits or as mandated by Applicable Law).

(g) None of the Company or any ERISA Affiliate sponsors, maintains or contributes to, or has at any time in the preceding six calendar years, sponsored, maintained or contributed to, any Multiemployer Plan.

(h) None of the Company or any ERISA Affiliate is required to provide security under section 401(a)(29) of the Code due to a Plan amendment that results in an increase in current liability for the Plan.

(i) The Disclosure Letter lists all Plans that the Company or any ERISA Affiliate has had at any time in the prior six (6) years.

3.10 Taxes. Except as described in the Disclosure Letter, the Company has filed all United States Federal income tax returns and all other tax returns which are required to be filed by it and has paid all taxes due pursuant to such returns or pursuant to any assessment received by the Company, except for any taxes which are being contested in good faith and by proper proceedings and against which adequate reserves are being maintained. The charges, accruals and reserves in respect of taxes and other governmental charges set forth on the face of the most recent balance sheet included in the most recent Company Report are, in the opinion of the Company, adequate. No tax lien has been filed and, to the knowledge of the Company, no claim is being asserted with respect to any such tax, fee or other charge, except for any taxes, fees or other charges which are being contested in good faith and by proper proceedings and against which adequate reserves are being maintained.

6

3.11 Titles, etc.

(a) Except as set forth in the Company Reports or in the Disclosure Letter, each of the Company and the Subsidiaries has good and defensible title, or valid leasehold interests to its assets and Properties, including, without limitation, the Oil and Gas Properties, free and clear of all Liens, other than Excepted Liens, except for minor defects and irregularities in title that are not substantial in character, amount, or extent. Except for immaterial divergences, after giving full effect to the Excepted Liens, the Company owns, in all material respects, the net interests in production attributable to the Hydrocarbon Interests, and the ownership of such Hydrocarbon Interests shall not in any material respect obligate the Company to bear the costs and expenses relating to the maintenance, development and operations of each such Hydrocarbon Interest in an amount in excess of the working interest of such Hydrocarbon Interest (without a corresponding increase in net revenue interest).

(b) All leases, licenses, permits, authorizations and agreements necessary for the conduct of the business of the Company and the Subsidiaries are valid and subsisting, in full force and effect and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such leases, licenses, permits, authorizations and agreements, which would have a Material Adverse Effect on the conduct of the business of the Company or its Subsidiaries.

(c) The Properties, including, without limitation, the Oil and Gas Properties, presently owned, leased or licensed by the Company and the Subsidiaries, including, without limitation, all easements, licenses, permits, authorizations and rights of way, include all Properties necessary to permit the Company and the Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the Closing Date.

(d) Except as described in the Disclosure Letter, all of the Properties of the Company and the Subsidiaries which are reasonably necessary for the operation of their business are in good working condition in all material respects and are maintained in accordance with prudent business standards.

3.12 No Material Misstatements. Taken as a whole, the written information, statements, exhibits, certificates, documents and reports furnished to the Investors by the Company or any Subsidiary in connection with the negotiation of this Agreement do not contain any material misstatement of fact or omit to state a material fact or any fact necessary to make the statements contained therein not materially misleading in the light of the circumstances in which made and with respect to the Company or any Subsidiary.

the Company or any Subsidiary prior to, or on, each Closing Date in connection with the transactions contemplated hereby.

8

(b) Without limitation of clause (a) above, no Property owned, leased or operated by the Company or any of its Subsidiaries, including, without limitation, any Oil and Gas Property of the Company or any of its Subsidiaries, nor the operations currently conducted thereon or, to the best knowledge of the Company, by any prior owner or operator of such Property or operation, are in violation of or subject to any existing, pending or threatened Proceeding by or before any court or Governmental Entity or the subject of any remedial obligations under applicable Environmental Laws;

(c) All notices, permits, licenses or similar authorizations, if any, required to be obtained or filed by the Company or any of its Subsidiaries in connection with the operation or use of any and all Property of the Company and each of its Subsidiaries, including without limitation present, or to the best of Company's knowledge, past treatment, storage, disposal or release of a hazardous substance or solid waste into the environment, have been duly obtained or filed, and the Company and each Subsidiary are in substantial compliance with the terms and conditions of all such applicable notices, permits, licenses and similar authorizations;

3.18 Compliance with the Law. Neither the Company nor any Subsidiary has violated any Governmental Requirement or failed to obtain any license, permit, franchise or other governmental authorization necessary for the ownership of any of its Properties, including, without limitation, its Oil and Gas Properties, or the conduct of its business, which violation or failure would have (in the event such violation or failure were asserted by any Person through appropriate action) a Material Adverse Effect. Except for such acts or failures to act as would not have a Material Adverse Effect, the Properties, including, without limitation, the Oil and Gas Properties (and properties unitized therewith), have been maintained, operated and developed in a good and workmanlike manner and in conformity with all applicable laws and all rules, regulations and orders of all duly constituted authorities having jurisdiction and in conformity with the provisions of agreements and other instruments comprising a part of the Properties, including, without limitation, all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties; specifically in this connection, but subject to the Material Adverse Effect qualification set forth above, (i) after the date hereof, no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) prior to the date hereof, and (ii) none of the wells comprising a part of the Oil and Gas Properties (or properties unitized therewith) are deviated from the vertical more than the maximum permitted by applicable laws, regulations, rules and orders, and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on properties unitized therewith, such unitized properties).

Section 3.18 does not apply to compliance with ERISA or applicable Environmental Laws, which are instead subject to Section 3.9 and Section 3.17, respectively.

3.19 Insurance. The Disclosure Letter contains an accurate and complete description of all material policies of fire, liability, workmen's compensation and other forms of insurance owned or held by the Company and each Subsidiary as of the date hereof. Except as set forth in the Disclosure Letter, all such policies are in full force and effect, all premiums with respect thereto covering all periods up to and including the date hereof and the Additional Closing Date have been, or will be, paid, and no notice of cancellation or termination has been received with respect to any such policy. Such policies are sufficient for compliance with all requirements of law and of all agreements to which the Company or any Subsidiary is a party; are valid, outstanding and enforceable policies; provide adequate insurance coverage in at least such amounts and against at least such risks (but including in any event public liability) as are usually insured against in the same general area by companies engaged in the same or a similar business for the assets and operations of the Company and each Subsidiary; will remain in full force and effect through the respective dates set forth in the Disclosure Letter with the payment of additional premiums; and, except as set forth in the Disclosure Letter, will not in any way be affected by, or terminate or lapse by reason of, the transactions contemplated by this Agreement. There are no material risks that the Company, the Subsidiaries or their respective Board of Directors or officers have designated as being self-insured. Neither the Company nor any Subsidiary has been refused any insurance with respect to its assets or operations, nor has its

10

coverage been limited below usual and customary policy limits, by an insurance carrier to which it has applied for any such insurance or with which it has carried insurance during the last three years.

3.22 Gas Imbalances. As of the date hereof, on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Company's or any Subsidiary's Hydrocarbon Interests which would require the Company or such Subsidiary to deliver five percent (5%) or more of the monthly production from the Company's and its Subsidiaries' Hydrocarbons produced on a monthly basis from the Hydrocarbon Interests, at some future time without then or thereafter receiving full payment therefor.

3.23 Brokerage Fees. The Company has not retained any financial advisor, broker, agent, or finder or paid or agreed to pay any financial advisor, broker, agent, or finder on account of the sale by the Company and the purchase by the Investors of the Notes and the Warrants pursuant to this Agreement, except for Sanders Morris Harris, Inc. ("SMH").

3.24 SEC Filings. During the preceding three (3) years, the Company has complied in all material respects with its obligations to file with the SEC all forms, reports, schedules, statements and other documents required to be filed by it under the Securities Act and the Exchange Act.

The SEC Filings, at the time filed, complied in all material respects with all applicable requirements of federal securities laws. None of the SEC Filings, including, without limitation, any financial statements or schedules included therein, at the time filed or as same may have been amended, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading.

5.12 Registration of Warrant Shares.

(a) The Company shall prepare and file with the SEC a registration statement on Form S-3, or any similar short-form registration under the Securities Act (the "Form S-3"), to register for resale from time to time, the Common Stock representing the Warrant Shares and the Director Warrants (the "Registrable Securities") promptly, but in no event more than 60 days following the Company's first Form 10-KSB filing after the Closing Date, and use its best efforts to cause the Form S-3 to become effective and remain effective for the period described in Section 5.12(c)(ii). As used herein, "register," "registered" and "registration" refer to a registration effected by preparing and filing the Form S-3, a registration statement or similar document (a "Registration Statement") in compliance with the Securities Act, and the declaration or order of effectiveness of such Registration Statement.

If the Company at any time proposes to file on its behalf and/or on behalf of any of its security holders other than the Investors ("Demanding Security Holders") a Registration Statement under the Securities Act on any form (other than a Registration Statement filed on Form S-4, Form S-8 or any similar or successor form or any other Registration Statement relating to an offering of securities solely to the Company's existing security holders or employees) to register the offer and sale of its Common Stock for cash, it will give written notice to the Investors at least twenty (20) days before the anticipated date of initial filing with the SEC of such Registration Statement, which notice shall set forth the Company's intention to effect such a registration, the class or series and number of equity securities proposed to be registered and the intended method

19

of disposition of the securities proposed to be registered by the Company. The notice shall offer to include in such filing all of the Registrable Securities.

(i) If any Investor desires to have Registrable Securities registered under this Section 5.12(b), it shall advise the Company in writing within fifteen (15) days after the date of receipt of such offer from the Company, setting forth the amount of such Registrable Securities for which registration is requested. The Company shall thereupon include in such filing the number of Registrable Securities for which registration is so requested, subject to the next sentence, and shall use commercially reasonable efforts to effect registration under the Securities Act of such Registrable Securities. If the managing underwriter of a proposed public offering shall advise the Company in writing that, in its opinion, the distribution of the Registrable Securities requested to be included in the registration concurrently with the securities being registered by the Company or any Demanding Security Holder would materially and adversely affect the distribution of such securities by the Company or such Demanding Security Holders, then all selling security holders (but not the Company or the Demanding Security Holders) shall reduce the amount of Registrable Securities of each intended to be distributed through such offering on a pro rata basis to the greatest aggregate amount that, in the opinion of such managing underwriter, would not materially and adversely affect the distribution of such securities.

(ii) Nothing in this Section 5.12(b) shall preclude the Company from discontinuing the registration of its securities being affected on its behalf under this Section 5.12(b) at any time prior to the effective date of the registration relating thereto.

(b) In connection with the Company's registration obligations pursuant to this Section 5.12, the Company shall keep each Registration Statement continuously effective to permit the sale of Registrable Securities covered by such Registration Statement in accordance with the intended method or methods of distribution thereof specified in such Registration Statement or in the related prospectus(es), and shall:

(i) prepare and file with the SEC a Registration Statement with respect to such securities and use commercially reasonable efforts to cause such Registration Statement to become and remain effective for the period described in paragraph (f) below;

(ii) prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all securities covered by such Registration Statement until such time as all of such securities have been disposed of in a public offering;

(iii) furnish to such selling security holders such number of copies of a summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents, as

20

such selling security holders may reasonably request to facilitate the disposition of all Registrable Securities covered by the Registration Statement;

(iv) use commercially reasonable efforts to register or qualify the securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions within the United States as each holder of such securities shall reasonably request (provided, however, the Company shall not be obligated to qualify as a foreign corporation to do business under the laws of any jurisdiction in which it is not then qualified to file any general consent to service or process), and do such other reasonable acts and things as may be required of it to enable such holder to consummate the disposition in such jurisdiction of the securities covered by such Registration Statement;

(v) use commercially reasonable efforts to cause all Registrable Securities covered by each Registration Statement to be listed on the Nasdaq SmallCap Market, or, if the Common Stock of the Company is not listed thereon, on any national securities exchange, or inter-dealer quotations system (including Nasdaq) if any, on which the Common Stock is then listed or authorized for trading; and

(vi) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC or over-the-counter market where the Common Stock is then listed.

(c) All expenses incurred in complying with this Section 5.12, including, without limitation, all registration and filing fees (including all expenses incident to filing with the NASD), printing expenses, fees and disbursements of counsel for the Company, expenses of any special audits incident to or required by any such registration and expenses of complying with the securities or blue sky laws of any jurisdictions pursuant to Section 5.12(b)(iv), shall be paid by the Company.

(d) With respect to any Registration Statement filed or to be filed pursuant to this Section 5.12, if the Company's Board of Directors determines that, in its good faith judgment, it would (because of the existence of, or in anticipation of, any acquisition or corporate reorganization or other transaction, financing activity, stock repurchase or other development involving the Company, or the unavailability for reasons substantially beyond the Company's control of any required financial statements, or any other event or condition of similar significance to the Company) be disadvantageous (a "Material Development Condition") to the Company or its stockholders for such a Registration Statement to become effective or to be maintained effective or for sales of Registrable Securities to continue pursuant to the Registration Statement, the Company shall, notwithstanding any other provisions of this Agreement, be entitled, upon the giving of a written notice that a Material Development Condition has occurred (a "Delay Notice") from an officer of the Company to all affected holders of Registrable Securities, (i) to cause sales of Registrable Securities pursuant to such Registration Statement to cease, (ii) to cause such Registration Statement to be withdrawn and the effectiveness of such Registration Statement terminated, or (iii) in the event no such Registration Statement has yet been filed or declared effective, to delay filing or effectiveness of any such Registration Statement until, in the good faith judgment of the Company's Board

21

of Directors, such Material Development Condition no longer exists (notice of which the Company shall promptly deliver to all affected holders of Registrable Securities). Notwithstanding the foregoing provisions of this Section 5.12(e):
(1) in no event may any cessation or delay by the Company pursuant to this
Section 5.12(e) be for a period of more than one hundred twenty (120) consecutive days from the giving of the Delay Notice with respect to a Material Development Condition, as above provided, and in no event may such right be exercised by the Company on more than two (2) occasions during any period of twelve (12) consecutive months; and (2) in the event a Registration Statement is filed and subsequently withdrawn by reason of any existing or anticipated Material Development Condition as hereinbefore provided, the Company shall cause a new Registration Statement covering the same Registrable Securities as those covered by the original Registration Statement to be filed with the SEC as soon as practicable after such Material Development Condition expires or, if sooner, as soon as practicable after such 120 day period expires.

(e) The registration rights granted under this Section 5.12 shall terminate as to each Investor when all of the Registrable Securities of such Investor (i) shall have been effectively registered under the Securities Act and disposed of in a public offering pursuant to a Registration Statement, (ii) shall have been sold pursuant to Rule 144 (or any successor provision) under the Securities Act, (iii) shall have been otherwise transferred and a new certificate for such Warrant Shares not bearing a legend restricting further transfer shall have been delivered by the Company, (iv) with respect to a particular Investor, at any time when all of such Investor's remaining Warrant Shares can be sold in a single transaction in compliance with Rule 144 under the Securities Act, or (v) when the Warrants, and all of the associated Warrant Shares, shall have ceased to be outstanding.

(f) Except as contemplated in this Agreement as required by applicable securities laws, the Common Stock registered pursuant to the Registration Statement shall not be subject to any blackout, suspension or other trading restrictions. The Company shall give notice to the holders of Registrable Securities by email and/or facsimile of the Company's request for acceleration and of the effectiveness of the Registration Statement with the SEC, respectively, on the respective days that each of those events occur.

(g) The prospectus included in the Registration Statement (the "Prospectus") shall not be considered to be "current" at any time when, by reason of occurrence of any event or by reason of the passage of time, the Prospectus does not meet the requirements of Section 10 of the Securities Act, or the Prospectus contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus shall disclose that holders of Registrable Securities may elect to resell Registrable Securities without registration of such sales under the Registration Statement, by making such sales under and as permitted by Rule 144 of the SEC under the Act.

(h) Each Investor agrees in connection with any registration of the Company's securities upon the request of the Company and the underwriters managing any underwritten offering of the Company's securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Securities (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time not to exceed one hundred twenty

22

(120) days from the effective date of such registration as the Company and the underwriters may specify, so long as all officers and directors of the Company are bound by a comparable obligation provided, however, that nothing herein shall prevent any Investor from making a distribution of Registrable Securities to the partners or shareholders thereof that is otherwise in compliance with applicable securities laws, so long as such distributees agree to be so bound.

5.13 Confidentiality. Each Investor hereto agrees to treat all non-public information concerning the Company and its affiliates and Subsidiaries which was furnished by or on behalf of the Company, whether furnished before, on or after the date hereof confidential.

BLUE DOLPHIN ENERGY COMPANY

NEWS RELEASE

FOR IMMEDIATE RELEASE September 9, 2004

HOUSTON, TEXAS - BLUE DOLPHIN ENERGY COMPANY (NASDAQ SYMBOL: BDCO)

BLUE DOLPHIN ENERGY ANNOUNCES $750,000 DEBT FINANCING

Blue Dolphin Energy Company announced today that it has entered into an agreement with certain accredited investors and directors for the placement of promissory notes in an aggregate principal amount of $750,000 and 2.8 million warrants, at a price of $0.003 per warrant, to purchase shares of the Company's common stock. The sale of the promissory notes and the first tranche of 1.25 million warrants closed on September 8, 2004, and the second tranche of 1.55 million warrants is subject to stockholder approval, as well as customary closing conditions. The Company intends to hold a special meeting of its stockholders as soon as practicable to vote on, among other matters, the issuance of the second tranche of warrants.

The warrants have an exercise price of $0.25 per share and expire five years after their date of issuance. The promissory notes mature on December 7, 2004, and accrue interest at a rate of 12% per annum, of which 4% is payable monthly and 8% is payable at maturity. The promissory notes are secured by a second lien on the Company's Blue Dolphin Pipeline System. The maturity date of the promissory notes will be extended to September 7, 2005, if the Company's stockholders approve the issuance of the second tranche of warrants. In connection with this transaction, the directors, certain officers and a large stockholder, who combined represent approximately 41% of the Company's issued and outstanding common stock, have agreed to vote in favor of the issuance of the warrants in the second tranche, among other matters, pursuant to a voting agreement.

Pursuant to the terms of the agreement, the Company appointed F. Gardner Parker and Laurence N. Benz to its board of directors and has agreed to grant each of, subject to stockholder approval, Messrs. Parker and Benz and Michael S. Chadwick, an existing director, warrants to acquire 100,000 shares of the Company's common stock with an exercise price of $0.25 per share and a term of five years. Messrs. Parker and Benz each purchased a promissory note in the aggregate principal amount of $25,000. Mr. Parker purchased 41,663 warrants, and will purchase, subject to stockholder approval, 341,665 warrants in the second tranche. Mr. Benz purchased 41,667 warrants, and will purchase subject to stockholder approval, 41,667 warrants in the second tranche. Mr. Chadwick purchased a promissory note in the aggregate principal amount of $12,500, purchased 20,833 warrants, and will purchase, subject to stockholder approval, 20,834 warrants in the second tranche.

Mr. Chadwick is also a Senior Vice President and a Managing Director of Sanders Morris Harris Group, Inc. Several of the other investors that purchased securities in this placement are also affiliates of Sanders Morris Harris. Additionally, the Company paid Sanders Morris Harris a $25,000 fee in connection with this transaction and has agreed to retain Sanders Morris Harris as a financial advisor to identify strategic acquisition opportunities and assist the Company in evaluating and negotiating the terms of potential strategic transactions. In connection with its engagement, Sanders Morris Harris will assist the Company in formulating, evaluating and implementing possible alternatives for enhancing stockholder value.

Additionally, in August 2004, we restructured existing indebtedness to a vendor in the amount of $668,000 originally due in September and October 2004 to be payable in twelve monthly installments of $55,667 beginning September 1, 2004, plus interest on the outstanding balance at the rate of six percent per annum. The Company expects to use the proceeds from this offering for working capital and general corporate purposes. Without this financing, the Company expected to exhaust its cash and working capital during the fourth quarter 2004. The Company now believes that the proceeds from this offering will satisfy its working capital requirements through the first quarter 2005. However, the Company will still need to obtain additional capital to satisfy its cash and working capital requirements past the first quarter 2005. The Company has been seeking financing and selling


assets over the past several years to provide cash to meet obligations associated with the abandonment of an offshore oil and gas property and for its operating activities. Ivar Siem, Chairman of the Company, welcomes the addition of Messrs. Parker and Benz to the Board and said that "the financing will allow the Company to continue to operate and pursue the portfolio of opportunities currently being evaluated ".

The securities offered and sold in the private placement have not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. As part of the terms of the private placement, the Company is obligated to file a registration statement to register for resale under the Securities Act the shares of common stock underlying the warrants issued in the private placement.

The Company intends to file a proxy statement with the Securities and Exchange Commission (the "SEC") in connection with a special meeting of stockholders (the "Special Meeting") to vote on (i) the proposed issuance of the second tranche of 1.55 million warrants to purchase shares of the Company's common stock, (ii) the issuance of warrants to certain of the Company's directors (iii) the election of directors, and (iv) the amendment and restatement of the Company's certificate of incorporation. In conjunction with the transaction, the directors, certain officers and a large stockholder of the Company, who combined represent approximately 41% of the Company's outstanding common stock, have agreed to vote in favor of the issuance of the second tranche of warrants and other matters pursuant to a voting agreement with the investors. The Company and certain other persons named below may be deemed to be participants in the solicitation of proxies to approve these proposed matters. Participants in this solicitation may include the directors of the Company (Laurence N. Benz, Michael S. Chadwick, Harris A. Kaffie, F. Gardner Parker, Ivar Siem and James M. Trimble); and the executive officers of the Company (Mr. Siem, Michael J. Jacobson and G. Brian Lloyd). As of September 8, 2004, except for (i) Mr. Parker who may be deemed to beneficially own approximately 40.7% of the Company's outstanding common stock,
(ii) Mr. Siem who may be deemed to beneficially own approximately 14.1% of the Company's outstanding common stock, (iii) Mr. Kaffie who may be deemed to beneficially own approximately 11.8% of the Company's' outstanding common stock, and (iv) Mr. Jacobson who may be deemed to beneficially own approximately 2.9% of the Company's outstanding common stock, no participant may be deemed to beneficially own more than 1% of the Company's outstanding common stock. Additional information about the interests of the Company's directors and officers is contained in the Company's annual report on Form 10-KSB/A for the fiscal year ended December 31, 2003 filed with the SEC and will be in the proxy statement to be filed with the SEC in connection with the Special Meeting.

Certain of the statements included in this press release, which express a belief, expectation or intention, as well as those regarding future financial performance or results, or which are not historical facts, are "forward-looking" statements as that term is defined in the Securities Act of 1933, as amended and the Securities Exchange Act of 1934, as amended. The words "expect", "plan", "believe", "anticipate", "project", "estimate", and similar expressions are intended to identify forward-looking statements.
