Mr. James L. Wewers
President, El Dorado Chemical Company
P.O. Box 1373
Oklahoma City, Oklahoma  73101

Re:   Amended and Restated Secured Credit Agreement dated as of January 21,
      1992 (as amended, the "Secured Credit Agreement") among El Dorado
      Chemical Company ("EDC"), Slurry Explosive Corporation ("Slurry"),
      Connecticut Mutual Life Insurance Company, C.M. Life Insurance Company
      and Household Commercial Financial Services, Inc. ("HCFS"), and the
      Second Amended and Restated Working Capital Loan Agreement dated as of
      January 21, 1992 (as amended, the "Working Capital Agreement") between
      EDC, Slurry, and HCFS (collectively, the "Agreements").

Dear Mr. Wewers:

Reference is hereby made to the above-captioned Agreements.  Unless otherwise
defined herein or the context hereof otherwise requires, terms which are
defined or defined by reference in the Agreements or any exhibit thereto shall
have the same meanings when used in this letter as such terms have in the
Agreements.

EDC has informed HCFS that the extremely high recent costs of ammonia, which
EDC requires as a key raw material in its production process, and the extended
duration of this pricing has had a negative impact on EDC's performance during
the last 12 months.  EDC has further indicated that these ammonia costs are
anticipated to remain high for an unspecified additional period of time.  As a
result of this ammonia pricing environment, EDC has informed HCFS that it was
not in compliance with the Fixed Charge Coverage Ratio covenant for the month
of July as stipulated in Section 11.2 of the Secured Credit Agreement and
Section 11B.2 of the Working Capital Agreement and does not anticipate being
in compliance with these covenants during the next 6-12 months.

As requested by EDC, HCFS as Agent and Required Lender hereby amends the
Agreements by replacing the tables in Sections 11.2 of the Secured Credit
Agreement and 11B.2 of the Working Capital Agreement with the following table.

      Period                                          Ratio
July 1, 1994 through June 30, 1995                    2.00:1
July 1, 1995 through July 31, 1995                    2.10:1
August 1, 1995 through August 31, 1995                2.20:1
September 1, 1995 through September 30, 1995          2.30:1
October 1, 1995 through October 31, 1995              2.40:1
November 1, 1995 and Thereafter                       2.50:1


Subject to the terms and conditions herein, we are please to provide this
accommodation to EDC.  This amendment is limited to the specific matter set
forth herein and does not in any other matter waive, amend, or alter the
Agreements or other Loan Documents, the provisions of which shall remain in
full force and effect.

Sincerely,


James J. Russell
Assistant Vice President
