                                   (Unaudited)

1.   Basis of Presentation

The accompanying  condensed  consolidated  balance sheet as of December 31, 1997
and the statements of operations  and cash flows for all periods  presented have
been prepared by Advanced Communication Systems, Inc. ("the Company"),  and have
not been audited.  These  financial  statements,  in the opinion of  management,
include all adjustments,  consisting of normal recurring adjustments,  necessary
for a fair  presentation  of the financial  position,  results of operations and
cash flows for all periods  presented.  These condensed  consolidated  financial
statements should be read in conjunction with the financial statements and notes
thereto for the fiscal year ended  September  30, 1997 included in the Company's
Annual  Report on Form  10-K.  Interim  operating  results  are not  necessarily
indicative of operating results for the full year.

2.   Management's Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
reported  amounts of revenues and expenses during the reporting  period.  Actual
results could differ from those estimates.

3.   Provision for Income Taxes

Prior to June 25, 1997,  the Company  elected to be treated as an S  corporation
and was not subject to federal and certain state income taxes.  As a result,  no
provision for federal or state income taxes has been included in the  historical
statements of operations prior to June 25, 1997. On June 25, 1997, in connection
with the  initial  public  offering  the S  corporation  status was  terminated,
thereby  subjecting  future  income of the Company to federal  and state  income
taxes at the  corporate  level.  Subsequent  to June 25,  1997,  the Company has
provided  for federal and state  income taxes in the  statements  of  operations
based on the effective tax rate.

4.   Pro Forma Net Income Per Share

Pro forma net income is based on the assumption that the Company's S corporation
status was  terminated  at the  beginning of the year.  Pro forma net income per
share has been  computed  by  dividing  pro  forma  net  income by the pro forma
weighted average number of common shares outstanding during the period.

5.  Recently Issued Financial Accounting Standards

The Company  adopted the  Financial  Accounting  Standards  Board  Statement  of
Financial Accounting Standards (SFAS) No. 128, Earnings per Share, for the three
months ended  December  31,  1997.  SFAS No. 128 requires the Company to present
basic and  diluted  net income  per share on the face of the  income  statement.
Basic  net  income  per  share  is  computed  by  dividing  net  income  by  the
weighted-average number of common shares outstanding for the period. Diluted net
income  per  share  is  computed  by  dividing  net  income  by  the  sum of the
weighted-average number of common shares outstanding for the period end plus the
assumed exercise of all dilutive securities,  such as stock options. Diluted net
income per share for the periods  presented is not materially  different for net
income per share reported under Accounting Principles Board Opinion No. 15.

6. Acquisition

Effective  October 31, 1997, the Company acquired all of the outstanding  shares
of common stock of Integrated  Systems Control,  Inc.  ("ISC"),  in exchange for
475,000 shares of the Company's common stock. 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 fair
market value of the assets  acquired is being  classified as intangible  assets,
principally goodwill, and will be amortized over its estimated useful life of 30
years.

The  following  unaudited  pro  forma  summary  presents  information  as if the
acquisition  had occurred at the  beginning  of each fiscal year.  The pro forma
information  does not  necessarily  reflect the actual  results  that would have
occurred nor is it necessarily indicative of future results of operations of the
combined companies.

Three Months Ended December 31, 1997 Compared to Three Months Ended 
December 31, 1996 

Revenues increased 56.3%, or $5.1 million, to $14.2 million for the three months
ended  December  31, 1997,  from $9.1  million for the same period in 1996.  The
increase  was  principally  due to an increase in  revenues  from  communication
systems,  primarily  under  contracts  with the U.S.  Navy,  resulting  from the
Company's acquisitions of RF Microsystems, Inc. and ISC.

Direct costs include labor costs,  related fringe benefits,  subcontract  costs,
material  costs and other  non-overhead  costs  directly  related to a contract.
Direct costs  increased to $9.1 million for the three months ended  December 31,
1997 from $6.0  million for the same period in 1996 due  primarily  to increased
revenues  from  the  Company's  acquisitions.   Direct  costs,  expressed  as  a
percentage of revenues,  decreased to 64.4% for the three months ended  December
31, 1997 from 66.6% for the same period in 1996,  primarily due to a decrease in
the  proportion  of revenues  coming from systems  integration  services.  These
services have higher direct costs than the other services the Company  provides
because  the  contracts  generally  require  the  Company to  purchase  hardware
components as part of the services.

Indirect, general and administrative expenses include fringe benefits, overhead,
selling  and  administrative  costs,  depreciation  and  amortization,  bid  and
proposal costs and research and development expenses. Indirect expense increased
to $3.9 million for the three  months ended  December 31, 1997 from $2.4 million
for the same period in 1996.  The increase was due primarily to the higher level
of revenues  discussed above.  Indirect  expenses,  expressed as a percentage of
revenues,  increased to 27.8% from 26.9% for the three months ended December 31,
1997, due to the higher  proportion of  communication  systems  revenues,  which
typically have higher associated indirect expenses.

Income from  operations  increased  88.7%,  to $1.1 million for the three months
ended  December 31, 1997,  from $586,000 for the same period in 1996,  primarily
due to increased  communication systems revenues from U.S. Navy contracts.  As a
percentage of revenues,  income from operations  increased to 7.8% for the three
months ended December 31, 1997, from 6.5% for the comparable period in the prior
year,  principally  attributable  to  increased  revenues  from fixed  price and
time-and-materials type contracts which typically carry higher margins.

Other expense,  net,  consists of interest  expense,  offset in part by interest
income  from  short-term  deposits  of cash.  Interest  expense  was $89,000 and
$64,000  for  the  three  month  periods  ended  December  31,  1997  and  1996,
respectively. Interest income was $11,000 and $16,000 for the three months ended
December 31, 1997 and 1996, respectively.

The Company's  effective tax rate was 36.4% for the three months ended  December
31, 1997.  The  Company's  pro forma  effective tax rate was 39.0% for the three
months ended December 31, 1996.

Liquidity and Capital Resources

The Company used cash from  operating  activities  of $4.0 million for the three
months ended December 31, 1997,  resulting primarily from net income,  increases
in contract  receivables and decreases in accrued expenses and accounts payable.
The increase in contract  receivables was due to increased revenues from the two
large U.S. Navy  contracts  awarded to the Company  during fiscal 1997.  For the
three months  ended  December  31,  1996,  the Company used cash from  operating
activities  which  amounted to $336,000,  resulting  primarily  from net income,
increases in contract  receivables,  decreases in accounts payable and partially
offset by increases in accrued expenses.

The  principal  use of cash for  investing  activities  was for the  purchase of
computers and equipment.  These purchases  totaled $235,000 and $187,000 for the
three  months  ended  December  31, 1997 and 1996,  respectively.  Further,  the
Company invested $239,000 in software development costs for its latest Microsoft
Exchange-based  product,  ISALTS 2000,  in the three  months ended  December 31,
1997.

The Company currently has a lines of credit with commercial banks under which it
can  borrow up to a maximum of $6.5  million.  As of  December  31,  1997,  $2.6
million was outstanding  under these  facilities.  One of the Company's lines of
credit for $5.0 million is due to expire in February 1998. The Company is in the
process of replacing this facility.
