                  On December 5, 1997, Advanced  Communication  Systems, Inc., a
Delaware corporation ("ACS"), filed a Current Report on Form 8-K with respect to
its November 26, 1997,  acquisition (the  "Acquisition")  of all the outstanding
shares of Integrated Systems Control, Inc., a Virginia corporation ("ISC"). Such
Form 8-K was filed  without the  financial  statements  and pro forma  financial

auditor's  report  thereon,  as of September 30, 1997 and 1996,  and the related
statements of income, retained earnings and cash flows for the years then ended,
are included at Exhibit 99(a) and incorporated herein by reference.

                  (b) Pro forma unaudited  financial  information for ACS giving
effect to the  Acquisition  as of and for the fiscal  year ended  September  30,
1997, is included at Exhibit 99(b) and incorporated herein by reference.

                  (c)  Exhibits:

                           99(a)  Audited  balance  sheets  of  ISC,   including
                  independent auditor's report thereon, as of September 30, 1997
                  and 1996,  and the  related  statements  of  income,  retained
                  earnings and cash flows for the years then ended.
                           99(b) Unaudited pro forma  financial  information for
                  ACS giving effect to the Acquisition as of, and for the period
                  ended September 30, 1997.
