for the Purchased Interests shall be (i) U.S. $2,795,788 (the "Cash Payment"),
(ii) the assumption by Buyer of the Assumed Obligations (as defined in Section

Purchase Price shall be allocated to Class III assets as defined in Temporary
Treasury Regulation ss. 1.1060-1T(d)(2)(ii) and among the Purchased Interests in

adjusted in the event Buyer reasonably determines within 90 days of Closing that

      (a) Seller may receive up to a maximum of an additional Five Hundred
Thousand Dollars ($500,000) of Conditional Consideration during the four (4)
year period following the Effective Time provided the Pre-Tax Cash Flow
allocated and distributed to Buyer exceeds certain target levels.

                        (i) Pre-Tax Cash Flow means Buyer's share of
                  Distributable Proceeds (as defined in the applicable Operating
                  Agreements) from the Purchased Interests and the Black Marlin
                  Interests distributed to it pursuant to the applicable
                  Operating Agreement with respect to the revenues realized
                  during the period in question. Capital expenditures shall be
                  deducted from Pre-Tax Cash Flow, provided, however, that if
                  capital expenditures are made in anticipation of the
                  generation of incremental revenue, then the annual economic
                  depreciation amount computed under generally accepted
                  accounting principles plus a 15% pre-tax return on the capital
                  expenditures will instead be deducted from Pre-Tax Cash Flow.

                        (ii) Conditional Consideration shall be paid on an
                  annual basis equal to one hundred percent (100%) of the
                  excess, if any, of the Pre-Tax Cash Flow for each twelve month
                  period following March 1, 1999 above the Adjusted Pre-Tax Cash
                  Flow Annual Target set forth in the following schedule:

      (b) Buyer shall deliver or make available to Seller not later than April 1
of each year, a statement of the Pre-Tax Cash Flow for the twelve month period
ending the last day of February of each year (terminating on February 28, 2003)
and a determination of the Conditional Consideration, if any, to be paid to
Seller. Seller shall have twenty (20) calendar days after the information
specified in the preceding sentence is delivered or made available to them to

examine such information and to present any objections that the Seller may have
to such information, such objections shall be set forth in writing and in
reasonable detail. Thereafter, Seller and Buyer shall promptly meet to discuss
any of the objections raised by the Seller, and shall mutually use good faith
efforts to resolve such objections. If the Seller does not deliver any written
objection to Buyer within such twenty (20) calendar day period, the Seller shall
be deemed to have accepted the determination of the Conditional Consideration
and waived any objection thereto. Any objections by Seller pursuant to this
provision that are not resolved within fifteen (15) calendar days after delivery
of such written objections by the Seller, may be referred to a Arbitrating
Accountant. The decision of the Arbitrating Accountant shall be binding and
conclusive upon both Buyer and Seller. All fees and expenses of the Arbitrating
Accountant will be paid one half by Buyer and one half by Seller. For purposes
of this section, the Arbitrating Accountant will be mutually selected by Buyer
and Seller from a nationally recognized firm of independent public accountants
with offices in Houston, Texas, or if no such selection is made, by the American
Arbitration Association at the request of either party.

      1.04 CUSTOMER CONTRACTS. The sale and purchase of the Purchased Interests
shall include an assignment of undivided 1/6 of 8/8ths interest in and to all of
the agreements described on Schedule 1.04 (the "Customer Contracts") pursuant to
which certain persons have entered into agreements with one or more of the Blue
Dolphin Companies with respect to (a) the transportation, separation,
dehydration, or storage of natural gas, crude oil, and/or condensate through,
by, and/or on certain of the Assets, or (b) the vapor recovery processes
performed by MEI.

      1.05 EFFECTIVE TIME. The transfer of the ownership of the Purchased
Interests shall be effective as of 9:00 a.m., Central Standard Time, on the day
of the Black Marlin Closing (the "Effective Time"). All sums owing on account of
the ownership, operation, or use of the Purchased Interests prior to the
Effective Time shall be for the account of and charged to the appropriate Blue
Dolphin Company, and all sums owing on account of the ownership, operation, or
use of the Purchased Interests on or after the Effective Time shall be charged
to and for the account of Buyer. The respective Blue Dolphin Company shall be
entitled to any and all revenues, refunds, sums or amounts attributable to the
ownership, operation, or use of the Purchased Interests prior to the Effective
Time. Buyer shall be entitled to any and all revenues, refunds, sums or amounts
attributable to the ownership, operation, or use of the Purchased Interests on
and after the Effective Time. Nothing set forth in this Section 1.05 shall be
construed, however, to supersede any agreements made pursuant to the Operating
Agreements with respect to the operation of the Assets subsequent to the
Effective Time, which shall be controlling for all such purposes. For purposes
of this Section 1.05, (a) revenues shall be treated as realized with respect to
the storage of crude oil, condensate, and natural gas liquids prior to the
Effective Time to the extent such liquids were in storage in or on the Assets at
the Effective Time and (b) such liquids shall be deemed delivered from storage
on a "FIFO" basis.

      1.06 OTHER AGREEMENTS. At the Closing, Buyer is entering into the (i)
Operating Agreements, and (ii) a purchase rights and participation agreement
identical in form and content to Exhibit 1.06 (the "Purchase Rights Agreement").

                                     CLOSING

      The closing of the transactions contemplated by this Agreement ("Closing")
is taking place simultaneously with the execution of this Agreement. The Closing
will only be effective on, and is contingent upon, the Black Marlin Closing. If
the Black Marlin Closing has not occurred by March 31, 1999, the Closing under
this Agreement and the Closing Agreements (as defined in Section 4.01(b)) shall
be null and void. The Closing pursuant to this Agreement may be revoked by Buyer
prior to the Effective Time if the Purchased Interests are materially damaged,
lost or destroyed prior to the Effective Time if such damage, loss or
destruction is not adequately compensated by insurance.

                                   ARTICLE III

      providing coverage equal to or greater than the coverage cancelled,
      terminated, or lapsed are in full force and effect and written copies
      thereof have been provided to Buyer;

consummate the transactions contemplated hereby. All costs and expenses of
obtaining or effecting any and all of the consents, approvals, orders,
authorizations, waivers, declarations, 

filings, and registrations referred to in this Section shall be borne by the

or amendment at or prior to the Closing shall be waived and no party shall be
entitled to make a claim thereon pursuant to the terms of this Agreement.

      ASSUMPTION AND INDEMNIFICATION

      7.01 ASSUMPTION OF LIABILITIES RELATING TO THE PURCHASED INTERESTS. As of
the Effective Time, Buyer shall assume and agree to pay, perform, and discharge
or cause to be paid, performed, and discharged all duties, obligations, and
liabilities ("Obligations") arising out of, in connection with, or otherwise in
respect of the ownership or operation of the Purchased Interests, whether
primary or secondary, fixed or contingent, arising after the Effective Time,
including a pro rata portion of the duties, obligations, and liabilities of the
Blue Dolphin Companies under the Customer Contracts and the Applicable Operating
Agreements (collectively, the "Assumed Obligations"); provided, however, that
Buyer does not assume any Obligations of the Blue Dolphin Companies associated
with or arising out of matters as to which a Blue Dolphin Company is obligated
to indemnify Buyer pursuant to Section 7.02.

      7.02 INDEMNIFICATION BY THE BLUE DOLPHIN COMPANY. Each Blue Dolphin
Company shall jointly and severally indemnify, defend, and hold harmless Buyer
(and its directors, officers, employees, affiliates, successors, and assigns)
from and against any Obligations based upon, arising out of or otherwise in
respect of (a) any inaccuracy in or breach of any representation, warranty, or
covenant of any Blue Dolphin Company contained in this Agreement; (b) any
Obligations arising out of, in connection with, or otherwise in respect to the
ownership of the Purchased Interests arising before the Effective Time, and (c)
any liability for Taxes the responsibility for the payment of which is retained
by that Blue Dolphin Company pursuant to Section 6.02(c); provided, however,
that the Blue Dolphin Companies shall have no liability under this Section 7.02
with respect to matters described in clause (a) above for Obligations until the
aggregate amount of such Obligations shall exceed the sum of $100,000 and, in
any event only with respect to the amount in excess thereof, subject at all
times, to the provisions of this Article VIII. Notwithstanding anything to the
contrary herein contained, the maximum aggregate 

amount of the obligations of the Blue Dolphin Companies to indemnify Buyer
pursuant to this Section 7.02 shall be the Purchase Price.

      7.03 INDEMNIFICATION BY BUYER. Buyer shall indemnify, defend, and hold
harmless each of the Blue Dolphin Companies (and their respective directors,
officers, employees, affiliates, successors, and assigns) from and against any
Obligations based upon, arising out of or otherwise in respect of (a) any
inaccuracy in or breach of any representation, warranty, or covenant of Buyer
contained in this Agreement; (b) any liability for Taxes the responsibility for
the payment of which is assumed by Buyer pursuant to Section 6.04(b) and (c)
hereof; and (c) the Assumed Obligations.

      7.04 NOTICE OF ASSERTED LIABILITY. Promptly after receipt by any party
hereto (the "Indemnitee") of notice of any demand, claim, or circumstance which,
with the lapse of time, would give rise to a claim or the commencement (or
threatened commencement), or any action, proceeding, or investigation (an
"Asserted Liability") that may result in an Obligation, the Indemnitee shall
give notice thereof (the "Claims Notice") to the other party hereto (the
"Indemnifying Party"). The Claims Notice shall describe the Asserted Liability
in reasonable detail, and shall indicate the amount (estimated, if necessary) of
the Obligation that has been or may be suffered by the Indemnitee.
Notwithstanding the foregoing, no party shall have any liability for claims
arising pursuant to Section 7.02(a) or 7.03(a) unless a Claims Notice has been
delivered within the appropriate time period indicated in Section 8.01.

      7.05 OPPORTUNITY TO DEFEND. The Indemnifying Party may elect to compromise
or defend, at its own expense and by its own counsel, any Asserted Liability and
if it does so the Indemnifying Party shall have the right to make all judgments
and decisions in respect of the handling of the defense of such Asserted
Liability and the settlement or compromise of the Asserted Liability, subject to
the provisions of this Section 7.05. If the Indemnifying Party elects to defend
such Asserted Liability, it shall within 30 days of the Claims Notice (or
sooner, if the nature of the Asserted Liability so requires) notify the
Indemnitee of its intent to do so, and the Indemnitee shall cooperate, as
requested by and at the expense of the Indemnifying Party, in the compromise of,
or defense against, such Asserted Liability. If the Indemnifying Party elects
not to defend the Asserted Liability, fails to notify the Indemnitee of its
election as herein provided or contests its obligation to indemnify under this
Agreement, the Indemnitee may pay, compromise, or defend such Asserted
Liability. Notwithstanding the foregoing, neither the Indemnifying Party nor the
Indemnitee may settle or compromise any claim subject to indemnification over
the objection of the other, provided, however, that consent to settlement or
compromise shall not be unreasonably withheld. In any event, the Indemnitee and
the Indemnifying Party may participate, at their own expense, in the defense of
such Asserted Liability. If the Indemnifying Party chooses to defend any claim,
the Indemnitee shall make available to the Indemnifying Party any books,
records, or other documents within its control that are necessary or appropriate
for such defense.

      7.06 NEGLIGENCE AND STRICT LIABILITY WAIVER. The indemnification provided
for in this Article VIII shall be applicable regardless of whether Obligations
in question arose solely or in part from the active, passive, or concurrent
negligence of any Indemnitee (or under any theory of strict liability) prior to
the Effective Time or after the Effective Time, as the case may be.

      7.07 EXCLUSIVE REMEDY. After the Closing, and to the extent permitted by
applicable law, the rights and remedies expressly set forth in this Agreement
and in the Closing Agreements shall be the exclusive rights and remedies of the
parties hereto with respect to losses or claims relating to the transactions
consummated pursuant to this Agreement.

three (3) years after the Effective Time with respect to any intentional and
willful misrepresentations set forth herein, after which time no claim or suit
may be brought with respect to the same and provided, however, that the
representations and warranties with respect to the Omega Pipeline shall expire
at the Closing.

      8.02 DUE DILIGENCE REVIEW. Buyer acknowledges that it has assumed the
responsibility for conducting its own due diligence review with respect to the
Assets and the transactions contemplated hereby. Buyer acknowledges that it has
been provided full access to such information as it has requested from the Blue
