                   UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS


                              BASIS OF PRESENTATION

The accompanying unaudited pro forma condensed consolidated financial statements
give effect to the acquisition of SEMCOR, Inc. ("SEMCOR"), as described below.

Effective June 10, 1998, Advanced Communication Systems, Inc. ("ACS"), acquired
all of the outstanding common stock of SEMCOR for the preliminary purchase price
of $38 million, which consisted of $37 million in cash and $1 million in ACS
common stock. In addition, ACS will pay the shareholders up to $1.2 million for
certain income tax liabilities incurred as a result of the acquisition. The
preliminary purchase price is subject to adjustment based on the net equity
shown on the closing date balance sheet. The acquisition has been accounted for
as a purchase, and accordingly, the total purchase price has been allocated
among the acquired assets in accordance with the provisions of Accounting
Principles Board Opinion No. 16. The excess of the purchase price over the net
fair market value of the assets acquired is being classified as intangible
assets, principally goodwill, which will be amortized over its estimated useful
life.

The unaudited pro forma condensed consolidated balance sheet as of March 31,
1998, has been prepared to reflect the acquisition of SEMCOR as if it had
occurred on March 31, 1998, by combining the consolidated balance sheet of ACS
as of March 31, 1998, with the balance sheet of SEMCOR as of March 31, 1998. The
unaudited pro forma condensed consolidated statement of operations for the year
ended September 30, 1997, with appropriate adjustments, has been prepared by
combining the consolidated statement of operations of ACS for the period ended
September 30, 1997, with the historical results of operations of RF
Microsystems, Inc. ("RFM") for the nine months ended June 30, 1997, the audited
statement of income of Integrated Systems Control, Inc. ("ISC") for the twelve
months ended September 30,1997, the audited statement of operations of AMI for
the twelve months ended December 31, 1997, and the audited statement of income
of SEMCOR for the twelve months ended December 31, 1997, to reflect the
acquisitions of AMI, ISC, RFM and SEMCOR as if they had occurred at the
beginning of the period presented. The unaudited pro forma condensed
consolidated statement of operations for the nine months ended June 30, 1998,
with appropriate adjustments, has been prepared by combining the consolidated
statement of operations of ACS for the nine months ended June 30, 1998, with the
historical pre-acquisition results of operations of AMI for the four months
beginning October 1, 1997 through January 31, 1998, and the historical
pre-acquisition results of operations of SEMCOR for the period beginning October
1 1997 through June 9, 1998, to reflect the acquisitions of AMI and SEMCOR as if
they had occurred at the beginning of the period presented.

The unaudited pro forma condensed consolidated financial statements have been
prepared by the ACS's management and should be read in conjunction with the
historical financial statements of ACS and AMI and the related notes thereto.
The unaudited pro forma condensed consolidated statements of operations are not
necessarily indicative of the results of operations that may have actually
occurred had the acquisition occurred on the dates specified, or of the future
results of the combined companies. The pro forma adjustments are based upon
available information and certain adjustments that the management of ACS
believes are reasonable. In the opinion of ACS's management, all adjustments
have been made that are necessary to present fairly the unaudited pro forma
condensed consolidated financial statements.
