ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

Lone Star International Energy, Inc. (Company) consummated the acquisition of

effective April 2, 1997 all of the authorized, issued and outstanding stock of

was owned beneficially and/or of record by Cline. As consideration, the Company
issued to Calvin D. Cline a total of 3,333,333 unregistered Rule 144 Restricted

and consideration paid were based on an arms length foundation.

At closing, ERR became a wholly owned subsidiary of the Company, and Calvin D.

he will serve as President and a Director of ERR.  The Employment and Service
Contract provides for a five year primary term with automatic rollovers of five
year terms.  Initial compensation under the Employment and Service Contract was
$250,000.00 Annually.

ERR was recently formed Texas Corporation, and had no historical operations.
ERR is the owner of certain intellectual property and patents which have been
issued by the United States Patent office, and/or Applications for Patents are
currently pending.  Included as assets of ERR are Patent No. 5,490,398 dated
February 13, 1996, Patent application pending, serial No. 08/586,630 approved
to issue by the United States Patent office and two patents filed on an

Maritime industry and the prototype production of the Absorption Refrigeration
System designed for the utility industry.  The Company will also own any
amendments, revisions, or modifications of the Patents developed by Calvin D.
Cline and ERR.

this time.  These valuations will be provided in an amended Form 8-K Report to
be filed.

notices giving rise to or evidencing the Intellectual Property and the Leases
are valid, in full force and effect and, to the best knowledge of the
Representing Shareholder and ERR, are enforceable in accordance with their
terms against any adverse party.  There has not occurred any event that would
constitute a breach or default by ERR of any material covenant or condition of
giving rise to any of the Intellectual Property or Lease, nor has there
occurred any event that with the passage of time or the giving of notice or
both would constitute such a breach or default.  None of the Intellectual
Property or Leases imposes any restrictions that would materially interfere

Representing Shareholder or ERR, threatened eminent challenge to any aspect of

       nor any trust

       created thereunder, nor any trustee or administrator thereof, has
       knowingly engaged in a transaction in connection with which ERR is
       subject to the imposition of either a civil penalty assessed pursuant to
       Section 502(i) of ERISA or a tax imposed pursuant to Section 4975 of the
       Internal Revenue Code of 1986, as amended (the "Internal Revenue Code");

       not been satisfied in full, other than liability for premiums that are
       not yet due and payable to the Pension Benefit Guaranty Corporation, and
       there exist no facts or circumstances which are expected to result in
       such liability; (D) in accordance with Financial Accounting Standards
       Board Statement No. 87, the aggregate assets of all ERISA Pension Plans
       that are subject to Title IV of ERISA exceed the present value of the
       aggregate accumulated benefit obligations (vested and non-vested)
       accrued under all such plans as of January 1, 1988; and (E) ERR has not
       announced any plan or legally binding commitment to create any
       additional Company Plans or to modify or change any of the Company Plans
       except as required by law.  The Internal Revenue Service has issued a
       letter for each ERISA Pension Plan determining that each plan is exempt
       from United States federal income tax under Section 409(a) and 501(a) of
       the Internal Revenue Code and there has been no occurrence since the
       date of any such determination letter which has adversely affected such
       qualification.

              (c) Each Company Plan that is an "employee benefit plan," as such
       term is defined in Section 3(3) of ERISA (each an "Employee Benefit
       Plan") complies in all material respects with all applicable
       requirements of ERISA and of the Internal Revenue Code, and other
       applicable laws.  Neither ERR, nor any of its directors, officers,
       employees or agents has, with respect to any Employee Benefit Plan,
       engaged in any "prohibited transaction" as such term is defined in
       Section 4975 of the Internal Revenue Code or Section 406 of ERISA, or
       any conduct that would result in any taxes or penalties on prohibited
       transactions under Section 4975 of the Internal Revenue Code or under
       Section 502(i) of ERISA or in breach of fiduciary duty liability under
       Section 409 of ERISA, which in the aggregate could be material to the
       business, financial condition or results of operations of ERR.  No
       withdrawal liability has been incurred by or asserted against ERR with
       respect to any Employee Benefit Plan which is a "multi-employer plan"
       (as defined in Section 3(37) of ERISA).

              (d) Except as set forth in SCHEDULE 2.24, ERR is not a party to
       or obligated under any agreement, stock option, plan, contract or other
       arrangement pursuant to which compensation, property or benefits will
       become payable as a result of the consummation of the transactions
       contemplated.

              (a)    Employer reserves the right to terminate this agreement if
                     Employee willfully and substantially breaches or

                     any physical or mental disability that would prevent the
                     performance of his duties under this agreement.  Such a
                     termination shall be effected by given sixty (60) days'
                     written notice of termination to Employee.  Termination
                     pursuant to this provision shall not prejudice Employee's
                     rights to continued compensation pursuant to Section 4.02
                     and 4.03 of this agreement.

the benefit of creditors occurs, or upon the voluntary winding up or
liquidation of its business by Employer hereto, whether or not with the aid and
assistance of any court.
