                                  TO THE
                          1992 STOCK OPTION PLAN
                                    OF
                      SIERRA TUCSON COMPANIES, INC.

     1.   Background.

          Sierra Tucson Companies, Inc. (the "Company") has previously
established a 1992 Stock Option Plan (the "Plan") for the purpose of
advancing the interests of the Company by providing officers, directors and
key employees of the Company and its subsidiaries, as well as non-employee
independent contractors of the Company, with additional incentive for them
to promote the success of the Company's business.  Section 6(b) of the Plan
provides that the aggregate number of shares of the Company's common stock
that may be issued upon the exercise of all options which may be granted
under the Plan will not exceed 750,000.

          The Company believes that it is in its best interests (a) to
increase the maximum number of shares issuable upon the exercise of all
options that may be granted under the Plan to a total of by 750,000 shares
to a total of 1,500,000 shares; (b) to insure that the Plan complies with
the provisions of Rule 16b-3 or its successors as promulgated by the
Securities and Exchange Commission pursuant to Section 16 of the Securities
Exchange Act of 1934.

          Pursuant to Section 13 of the Plan, the Board of Directors of the
Company has approved the amendments to the Plan set forth herein.

     2.   Amendment to Section 5 of the Plan.

          Section 5 of the Plan is amended to add a new paragraph D to read
as follows:

          "D.  Limitation on Number of Options

          No person shall be granted, in any twelve (12) month period,
options to purchase in excess of 200,000 shares of the common stock of the
Company."

     3.   Amendment of Section 6 of the Plan.

          Section 6(b) of the Plan is hereby amended to increase the
aggregate number of shares of the Company's common stock that may be issued
upon the exercise of all options which may be granted under the Plan by
750,000 shares (the "Additional Shares") to an aggregate amount of
1,500,000.

     4.   Rule 16b-3 Compliance.
          A new Section 24 is added to the Plan to read as follows:
<PAGE>

          "24. COMPLIANCE WITH RULE 16b-3
               With respect to the issuance of options hereunder to persons
     subject to Section 16 of the 1934 Act, transactions under this Plan
     are intended to comply with all applicable conditions of Rule 16b-3 or
     its successors under the 1934 Act.  To the extent any provision of
     this Plan or action by the Board or Stock Option Committee in
     administering this Plan fails to so comply, it shall be deemed null
     and void, to the extent permitted by law and deemed advisable by the
     Board or the Stock Option Committee."

     5.   Continued Effect of Plan.

          Except as otherwise amended hereby, the Plan shall remain in full
force and effect.

     6.   Effective Date of Amendment.

          This Amendment became effective upon its adoption by the Board on
February 4, 1995 (the "Effective Date"); provided, however, that the
shareholders of the Company shall approve the amendment to Section 6 of the
Plan as provided in Paragraph 2 above, in accordance with applicable state
law, within twelve (12) months after the initial adoption of this Amendment
by the Board.  Notwithstanding the above, no options to acquire any of the
Additional Shares shall be granted to persons subject to Section 16 of the
1934 Act prior to approval of this Amendment by the shareholders of the
Company.  In the event that the amendment to Section 6 of the Plan is not
approved within said twelve (12) month period, all options to purchase the
Additional Shares shall nonetheless remain valid, but shall constitute Non-
Qualified Options.

     IN WITNESS WHEREOF, the Company has caused this Amendment to be
executed by its duly authorized officers effective as of the Effective
Date.

the Registration Statement.

options that may be granted under the Plan to a total of by 750,000 shares
to a total of 1,500,000 shares; (b) to insure that the Plan complies with
the provisions of Rule 16b-3 or its successors as promulgated by the
Securities and Exchange Commission pursuant to Section 16 of the Securities
Exchange Act of 1934.

          Pursuant to Section 13 of the Plan, the Board of Directors of the
Company has approved the amendments to the Plan set forth herein.

     2.   Amendment to Section 5 of the Plan.

          Section 5 of the Plan is amended to add a new paragraph D to read
as follows:

          "D.  Limitation on Number of Options

          No person shall be granted, in any twelve (12) month period,
options to purchase in excess of 200,000 shares of the common stock of the
Company."

     3.   Amendment of Section 6 of the Plan.

          Section 6(b) of the Plan is hereby amended to increase the
aggregate number of shares of the Company's common stock that may be issued
upon the exercise of all options which may be granted under the Plan by
750,000 shares (the "Additional Shares") to an aggregate amount of
1,500,000.

     4.   Rule 16b-3 Compliance.
          A new Section 24 is added to the Plan to read as follows:
"24. COMPLIANCE WITH RULE 16b-3
               With respect to the issuance of options hereunder to persons
     subject to Section 16 of the 1934 Act, transactions under this Plan
     are intended to comply with all applicable conditions of Rule 16b-3 or
     its successors under the 1934 Act.  To the extent any provision of
     this Plan or action by the Board or Stock Option Committee in
     administering this Plan fails to so comply, it shall be deemed null
     and void, to the extent permitted by law and deemed advisable by the
     Board or the Stock Option Committee."

     5.   Continued Effect of Plan.

          Except as otherwise amended hereby, the Plan shall remain in full
force and effect.

     6.   Effective Date of Amendment.

          This Amendment became effective upon its adoption by the Board on
February 4, 1995 (the "Effective Date"); provided, however, that the
shareholders of the Company shall approve the amendment to Section 6 of the
Plan as provided in Paragraph 2 above, in accordance with applicable state
law, within twelve (12) months after the initial adoption of this Amendment
by the Board.  Notwithstanding the above, no options to acquire any of the
Additional Shares shall be granted to persons subject to Section 16 of the
1934 Act prior to approval of this Amendment by the shareholders of the
Company.  In the event that the amendment to Section 6 of the Plan is not
approved within said twelve (12) month period, all options to purchase the
Additional Shares shall nonetheless remain valid, but shall constitute Non-
Qualified Options.

     IN WITNESS WHEREOF, the Company has caused this Amendment to be
executed by its duly authorized officers effective as of the Effective
Date.
