     THEREFORE,  in consideration of the premises,  the parties hereby agree, as
follows:

     1. Effective  September 1, 1997,  Section 1 of the Employment  Agreement is
hereby  amended by  deleting  all of Section 1 thereof and  substituting  in its
place the following:

     The  Employee  shall be employed on a  full-time  basis as Chief  Executive
Officer of the Company  and shall  perform  such  duties as the chief  executive
officer of the Company would normally  perform,  subject to the direction of the
Chairman of the Board of Directors of the Company (the "Chairman"), provided the
Chairman is a full-time  employee of the  Company,  and the Board of  Directors.
Until such time as the Company  employs a  President,  the  Employee  shall also
perform the duties of President of the Company,  subject to the direction of the
Chairman,  provided the Chairman is a full-time employee of the Company, and the
Board of Directors.  The Employee  understands that the position of President is
temporary  until such time as the Board of  Directors  elects a President of the
Company.  The  Employee  and the  Chairman  have on the date  hereof  executed a
memorandum of understanding  which  delineates the division of  responsibilities
between the Employee and the Chairman.

     2. Except as herein modified, the Employment Agreement shall remain in full
force and effect  according to its original  terms and  conditions as amended by
Amendment One thereto.


     IN WITNESS WHEREOF,  the parties have hereunto  executed this Amendment Two
