                   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 RF  Microsystems,  Inc.  ("RFM") as described
below.

Effective August 26, 1997, Advanced Communication Systems, Inc. ("ACS") acquired
all of the outstanding common stock of RFM in exchange for cash consideration of
$5,000,000.   The  acquisition  has  been  accounted  for  as  a  purchase,  and
accordingly,  the total purchase price has been allocated to the acquired assets
and  liabilities  assumed at their  estimated fair values in accordance with the
provisions of Accounting  Principles  Board Opinion No. 16. The estimated excess
of the purchase price over the net assets  acquired is being carried as goodwill
and will be  amortized  over its  estimated  life of 15  years.  The  charge  of
$1,910,000  resulting  from the write-off of purchased  in-process  research and
development  cost has been  excluded from the pro forma  condensed  consolidated
statements of operations.

RFM's  fiscal  year ended is January  31,  while the fiscal year ended of ACS is
September 30. The unaudited pro forma  condensed  consolidated  balance sheet of
ACS as of June 30, 1997, has been prepared by combining the consolidated balance
sheet of ACS as of June 30, 1997,  with the balance  sheet of RFM as of June 30,
1997. The unaudited pro forma condensed consolidated statement of operations for
the fiscal year ended  September 30, 1996, has been prepared by combining  ACS's
consolidated  statement of  operations  for the fiscal year ended  September 30,
1996,  with RFM's  statement of operations  for the twelve months ended December
31, 1996. The unaudited pro forma condensed consolidated statement of operations
for the nine months ended June 30, 1997,  has been  prepared by combining  ACS's
consolidated  statement of  operations  for the nine months ended June 30, 1997,
with RFM's  statement of operations for the nine months ended June 30, 1997. ACS
and RFM, on a combined basis, are referred to herein as the "Company".

The  unaudited  pro forma  condensed  consolidated  balance sheet as of June 30,
1997, has been prepared to reflect the  acquisition of RFM as if it had occurred
on June 30, 1997. The unaudited pro forma condensed  consolidated  statements of
operations,  with  appropriate  adjustments,  have been  prepared to reflect the
acquisition  of RFM as if it  had  occurred  at  the  beginning  of the  periods
presented.

The unaudited pro forma condensed  consolidated  financial  statements have been
prepared by the Company's  management and should be read in conjunction with the
historical financial statements of ACS and RFM and the related notes hereto. 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  occured on the dates  specified,  or of the future
results  of the  combined  Company.  The pro forma  adjustments  are based  upon
available  information  and certain  adjustments the management of ACS  believes
are reasonable.  In the opinion of management,  all  adjustments  have been made
that are  necessary  to present  fairly  the  unaudited  condensed  consolidated
financial statements.

additional amortization expense.

(D) Prior to June 25, 1997,  ACS elected to be treated as an S  Corporation  and
was not subject to federal and state income  taxes.  The pro forma  statement of
operations  data  reflects  federal and state income  taxes based on  applicable
rates as if ACS had not elected S Corporation status for the periods indicated.

(E) The statement of operations presentation excludes the effect of a $1,910,000
charge to operations taken at the time of acquisition for purchased research and
development   costs  related  to  acquired   technology  that  has  not  reached
technological  feasibility and that has no alternative future use. The statement
of operations  presentation also excludes consideration of integration costs and
potential cost savings because ACS has not completed its comprehensive review of
RFM's business, operations, capitalization and management.

additional amortization expense.

(D) Prior to June 25, 1997,  ACS elected to be treated as an S  Corporation  and
was not subject to federal and state income  taxes.  The pro forma  statement of
operations  data  reflects  federal and state income  taxes based on  applicable
rates as if ACS had not elected S Corporation status for the periods indicated.

charge to operations taken at the time of acquisition for purchased research and
development   costs  related  to  acquired   technology  that  has  not  reached
technological  feasibility and that has no alternative future use. The statement
of operations  presentation also excludes consideration of integration costs and
potential cost savings because ACS has not completed its comprehensive review of
