     "If, but only if, the Company does not exercise its option as set forth
     above in this Section 2.3 to buy all the Securities of an affected
     Shareholder other than Welker, then"

     6.  The phrase contained in the last paragraph of Section 2.3 (b) which

Securities" is hereby deleted and replaced by the following "does not exercise
its option to purchase and redeem all of the Securities as set forth above in
this Section 2.3" and the phrase "Section 2.3(e)" in said paragraph shall be
amended to "Section 2.3(d)".

     7.  Section 2.3(d) shall be deleted and shall be replaced by the following:

          "(d) The Company shall give written notice to the affected Management
     Shareholder and the Management Shareholders of the election to exercise its
