9.        Amendment to Schedule of Subsidiaries.  Schedule 1 to the Credit
Agreement is hereby amended to delete Lido Atlantic Trading Company,
Inc., Oil Field Systems Corporation and American Onshore Petroleum
Company, Inc. due to the merger of such Subsidiaries out of
existence.

10.       Revocation of Exchange Letters.  Reference is hereby made to (a)
that certain letter dated September 17, 1993, from Peter E. Lorenzen,
Vice President and General Counsel of Borrower addressed to the Banks
(the "Exchange Notice Letter"), pursuant to which the Banks were
notified of Borrower's intention to issue the First Convertible
Debentures in exchange for the First Convertible Stock (the
"Exchange"), and (b) the letter agreement (the "Collateral Waiver
Letter") dated as of October 6, 1993, by and between Borrower and
Banks regarding the Banks limited waiver of the right contained in
Section 5.1(b) of the Credit Agreement to require the grant of
certain Liens in connection with the Exchange.  Borrower has notified
Banks that it did not complete the Exchange and that it does not
currently intend to complete the Exchange.  As such, Borrower hereby
rescinds the Exchange Notice and Banks and Borrower hereby mutually
rescind the Collateral Waiver Letter, in each case to the same extent
as if such letters had never been executed or delivered.  As a result
of the foregoing, in the event Borrower elects to complete an
exchange of the First Preferred Stock for the First Convertible
Debentures in the future, it will be necessary for Borrower to again
comply with the requirements of Section 9.1 and 5.1(b) of the Credit
Agreement.

          the applicable Restricted Subsidiaries') corporate secretary,
          and (b) an opinion of Peter E. Lorenzen, Esq., in form and
          substance acceptable to the Banks, opining with respect to the
          matters set forth in Paragraph 12 hereof and such other
          materials as Agent shall reasonably request.

hereby certifies to each Bank that each representation and warranty
of it and the Restricted Subsidiaries contained in the Credit
Agreement and the other Loan Papers (after giving effect to this
Amendment) is true and correct on the date hereof and will be true
and correct on the Effective Date; provided, however, that the
