                                  EXHIBIT A

                          AMENDMENT TO LOAN DOCUMENTS


A.   The "Loan Documents" that are the subject of this Amendment include
     the following (as any of the foregoing have previously been amended,
     modified or otherwise supplemented):

     1.   Amended and Restated Loan Agreement dated as of June 30, 1996 (the
          "Agreement")

     2.   Extension Letter dated May 31, 1997

     3.   Amended and Restated Committed Line of Credit Note dated June 30,
          1996 (the "Note")

     4.   Amended and Restated Security Agreement dated as of June 30, 1996
          (the "Security Agreement")

     5.   Equipment Security Agreement dated August 15, 1996 (the "Equipment
          Security Agreement")

     6.   Assumption Agreement dated as of April 30, 1997.


B.   The Loan Documents are hereby amended as follows:

     1.   The Expiration Date, as set forth in the Note, is hereby extended
          from June 30, 1998 to June 29, 1999, or such later date as may be
          designated by the Bank by written notice from the Bank to the
          Borrower, effective on July 1, 1998.

     2.   A new Section 3.15 is added to the Agreement to read as follows:

          "Section 3.15. Year 2000.  The Borrower has reviewed the areas
          within its business and operations which could be adversely affected
          by, and has developed or is developing a program to address on a
          timely basis the risk that certain computer applications used by the
          Borrower may be unable to recognize and perform properly date-
          sensitive functions involving dates prior to and after December 31,
          1999 (the "Year 2000 Problem").  The Year 2000 Problem will not
          result, and is not reasonably expected to result, in any material
          adverse effect on the business, properties, assets, financial
          condition, results of operations or prospects of the Borrower, or the
          ability of the Borrower to duly and punctually pay or perform its
          obligations hereunder and under the other Loan Documents."

     3.   The financial and other covenants contained in the Addendum to the
          Agreement are hereby amended and restated in their entirety as set
          forth in Schedule I attached hereto and made a part hereof.

     4.   The Security Agreement and the Equipment Security Agreement are
          hereby cancelled and of no further force or effect. The Bank agrees
          to deliver to the Borrower (for filing by the Borrower), UCC-3
          termination statements for all security interests filed by the Bank
          against the assets of the Borrower as security for the Obligations.
