              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

                                  (UNAUDITED)





1.   In the opinion of Management, the accompanying unaudited consolidated
     condensed financial statements contain all adjustments, consisting of
     normal recurring items, necessary to present fairly the financial
     position, results of operations and cash flows for the periods shown.  It
     is the Company's policy to end its first three quarterly accounting
     periods on the last Friday of each quarter, which includes thirteen weeks
     of operations.  The fourth quarter ends on March 31.  The financial data
     included herein was compiled in accordance with the same accounting
     policies applied to the Company's audited annual financial statements,
     which should be read in conjunction with these statements.

     The results of operations for the twenty-six weeks ended September 29,
     1995, are not necessarily indicative of the results to be expected for the
     full year.


2.   Costs and estimated earnings in excess of billings on uncompleted
     contracts primarily represent revenue recognized on contracts, including
     retainage, for which billings could not be presented under the terms of
     the contracts at the balance sheet dates.


3.   During the twenty-six weeks ended September 29, 1995, 45,189 common shares
     were sold from the Company's Treasury and 1,274 were purchased.  The total
     number of treasury shares as of September 29, 1995, is 255,859.


4.   The Company granted 182,200 options to purchase stock through its equity
     incentive stock plan during the twenty-six weeks ended September 29, 1995,
     and 5,000 options to purchase stock through its non-employee director
     stock plan for the same period.  Options for 197,806 shares were
     exercisable and 443,785 were outstanding at September 29, 1995.

5.   The Company  reached a settlement with M-Wave, Inc., and its wholly-owned
     subsidiary, Poly Circuits, Inc., effective September 29, 1995.  The
     lawsuit was initiated by the Company in May 1994 against M-Wave and Poly
     Circuits seeking compensation for monetary damages incurred as a result of
     defective printed circuit boards manufactured for the Company and
     installed in the Company's wireless data transmission devices.  The
     Company recorded a charge included in the fiscal 1994 special charge, for
     the costs associated with the program to repair and replace these
     defective boards and the write-off of defective boards remaining in
     inventory.  The settlement received by the Company included $300,000 in
     cash and 20,000 shares of M-Wave stock, recorded at the closing price of
     $9.00 on the date of  transfer. Income of $480,000 was recorded net of
     $3,000 in associated legal fees as of September 29, 1995.  Additionally,
     the Company obtained the right to receive $300,000 in product at no cost
     to the Company.  This value of the product will be recorded by the Company
     if and when the Company exercises this right.

6.   The Company recorded $1,035,000 loss for the second quarter and $1,113,000
     loss for the year-to-date from its equity investment in ARIA.  The second
     quarter represents the first full quarter of operations after the transfer
     of the Commercial segment's net assets to ARIA, which was effective May
     31, 1995.  The Company would have reported $1,588,000 as of September 30,
     1994 and $1,012,000 as of September 29, 1995 earnings before income taxes
     and equity in net loss of affiliate had the transfer occured at the
     beginning of those periods.

     The Company accounts for its investment in ARIA under the equity method of
     accounting.  In applying the equity method of accounting, the Company
     utilizes a measure of its economic contribution percentage in determining
     its recordable share of ARIA losses.  Its percentage of economic
     contribution is generally calculated based on the ratio of assets
     contributed by the Company to the total initial capitalization plus new
     financing of ARIA.  Upon ARIA's attainment of profitable operations, the
     Company will record its share of earnings at the same percentage until
     such

     time as the Company's investment balance is restored to an amount equal to
     its pro rata share of ARIA's underlying equity.

     During the second quarter, the Company purchased from ARIA 12% senior
     subordinated notes in the amount of $1,000,000 with warrants to purchase
     up to 160,000 Class B common shares of ARIA.  Subsequent to quarter-end,
     the Company purchased an additional $500,000 of the same 12% senior
     subordinate notes with warrants to purchase up to 80,000 Class B common
     shares.

    Subsequent to the end of the second quarter, on November 9, 1995, ARIA
    filed a lawsuit in United States District Court, Western District of New
    York, against WinComm, Inc., alleging, among other things, repudiation and
    breach of an agreement (i) to cooperate in the development of a national
    wireless digital data network and (ii) to pay for certain data
    communications equipment and services purchased from ARIA, in an aggregate
    amount of approximately $2 million.  The suit seeks damages and specific
    performance of defendant's promise to make certain FCC licensed frequencies
    available to plaintiff and other compensatory and equitable relief.  The
    proceedings are at a very early stage and the defendant has not yet filed an
    answer.  As of September 30, 1995, ARIA had an outstanding receivable of
    approximately $2 million due from WinComm.  The ultimate outcome of such
    proceedings and the potential impact of the lawsuit and the breakdown of
    ARIA's relationship with WinComm on ARIA's financial statements (including
    its accounts receivable from WinComm) and on the Company's investment in
    ARIA cannot presently be determined.

                          ----------------------------

The Board of Directors and Shareholders
Comptek Research, Inc.:


We have reviewed the consolidated condensed balance sheet of Comptek Research,
Inc. and subsidiaries as of September 29, 1995, and the related consolidated
condensed statements of operations, shareholders' equity, and cash flows for
the thirteen and twenty six week periods ended September 29, 1995 and September
30, 1994.  These consolidated condensed financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit in
accordance with generally accepted auditing standards, the objective of which
is the expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the consolidated condensed financial statements referred to above
for them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Comptek Research, Inc.  and
subsidiaries as of March 31, 1995, and the related consolidated statements of
operations shareholders' equity, and cash flows for the year then ended (not
presented herein); and in our report dated May 9, 1995, except as to note 13
which is as of May 31, 1995, we expressed an unqualified opinion on those
consolidated financial statements.  Our report also contained an explanatory
paragraph referring to an uncertainty as to the ultimate outcome of an
arbitration proceeding involving a Company subsidiary and its investee which
seeks approximately $7.2 million in damages.  In our opinion, the information
set forth in the accompanying consolidated condensed balance sheet as of March
31, 1995, is fairly stated, in all material aspects, in relation to the
consolidated balance sheet from which it has been derived.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS


FINANCIAL CONDITION
- - -------------------
The Company's operations provided cash flow, for the second quarter, of
$999,000 compared with the net use of cash of  $679,000 during the first
quarter of fiscal year 1996.   This improvement is the result of the transfer
of the Company's Commercial Segment and its operating cashflow requirements to
ARIA Wireless Systems, Inc. ("ARIA").    Cash flows from operations in the
prior year were $950,000 higher due to collections of accounts receivable
during that period.

The cash flow from operations and financing activities,  provided cash for the
Company to purchase from ARIA 12% senior subordinated notes in the principal
amount of $1,000,000 with warrants to purchase up to 160,000 class B common
shares of ARIA.  Subsequent to quarter end, the Company purchased an additional
$500,000 of the same 12% senior subordinated notes from ARIA with warrants to
purchase up to an additional 80,000 class B common shares of ARIA.

The Company anticipates cash flow from operations and available funds from the
revolving credit agreement to be sufficient to satisfy operational and capital
expenditure needs of the Company for the remainder of the fiscal year.

Additionally, effective May 31, 1995, the Company completed a transaction which
transferred the net assets of the Company's Commercial segment to ARIA.  As a
result, all commercial telecommunications business activities are accounted for
using the equity method of accounting.

RESULTS OF OPERATIONS
- - ---------------------
Net sales for the second quarter were $13,228,000, a 16% decrease when compared
with the second quarter 1995. This decrease is primarily due to a lower than
previously experienced subcontractor activity on a U.S. Navy contract for
Electronic Combat Mission Support (ECMS).  When compared with the first
quarter of 1996, second quarter sales increased by 10% primarily due to
improving subcontractor activity levels on the same contract.  It is
anticipated that these levels will continue to improve over the remainder of
the fiscal year 1996.  Backlog at the end of the quarter was $70.1 million, an
increase of 25% from $56.3 at June 30, 1995.  During the second quarter the
Company received funding for the next contract year on the ECMS contract.
Backlog at the end of the first and second quarter consists entirely of Defense
Segment contracts.

Gross margin percentage (net sales minus cost of sales) year to date increased
to 17% compared with 14% for the same period in the prior year.  Increases in
gross margin are the result of reduced ECMS subcontractor work, which typically
provides relatively low profit margins.  Additionally, the gross margin for the
second quarter of fiscal 1996 increased due to the completion of a contract, by
the Defense segment, earlier than anticipated.  Also, the prior year's second
quarter gross margin was negatively affected by losses on commercial products.

During the second quarter, the Company elected to substantially increase
spending on selling and marketing efforts geared toward attracting new
customers in both foreign and domestic markets.  Such efforts included the
introduction of proprietary military products developed by the Company.  As a
result, Selling, General and Administrative (S,G&A) expense as a percent of
sales increased to 13% for the second quarter 1996 from 8% in the second
quarter 1995.  Similarly, year-to-date S,G&A as a percentage of sales increased
to 13.6% from 10% for the same period in the prior year.

Research and Development (R&D) decreased for the second quarter 1996 by
46% to $294,000 when compared with the second quarter 1995 of $544,000.  The
Company during the first quarter of 1996 transferred to ARIA the operations of
the Commercial segment.  The Commercial segment in the prior year accounted for
$460,000 of the Company's R&D spending.  The Defense R&D segment spending
increased in the current year second quarter by $210,000 and $373,000 year to
date, when compared with the prior year.  The additional expenditures are
associated with the participation in a development project with the U.S.
government as well as continuing development efforts





                                     -10-

<PAGE>   11

associated with the Segment's proprietary military products.  Overall R&D       
spending is anticipated to be less in fiscal 1996 as compared with fiscal 1995.

Income of $477,000 was recorded during the second quarter as a result of the
settlement of litigation between the Company and M-Wave, Inc., and its
wholly-owned subsidiary, Poly Circuits, Inc.  The Company received $300,000 in
cash and 20,000 shares of M-Wave, Inc. stock, recorded at the close price of
$9.00 on the date of transfer.  The Company also obtained the right to receive
$300,000 in products at no cost to the Company.  Refer to note 5 for additional
information regarding this settlement.

The Company recorded a $1,035,000 loss for the second quarter from its equity
investment in ARIA which, as a result of the combination effective May 31,
1995, represents all of the commercial telecommunications business activities
for the second quarter 1996.  The Company recorded a loss of $1,640,000
year-to-date for all of the commercial telecommunications business, compared
with a loss of $1,757,000 for the same period in 1995.  ARIA sales were
$1,635,000 and  $3,638,000 for the quarter and year to date ended September 29,
1995, respectively.  ARIA reported net losses for the same periods of
$1,135,000 and $1,213,000.  ARIA continues to provide total communication
service solutions to end users through the sale of equipment and enhances this
with its offering of Private Data Digital Network (PDDN) services .  Such
services are intended to provide a recurring revenue stream but will require
significant capital expenditures in the near term.

The Company has been advised that on November 9, 1995, ARIA filed a lawsuit
against WinComm, Inc., a Florida corporation, seeking damages and specific
performance for breach of an agreement to cooperate in the development of a
national wireless digital data network.  The breakdown of the business
relationship between ARIA and WinComm could have a substantial adverse effect
on ARIA's offering of PDDN services, its financial condition and statements,
and its future financial performance. Refer to note 6 for additional
information regarding ARIA and this litigation.

As of September 29, 1995, the Company's balance sheet reflects an investment in
ARIA of $7 million of the Company's total assets of $20 million.  The Company's
ability to recover its investment in ARIA is dependent upon, among other
things, the future profitability of ARIA and its ability to obtain additional
financing.



                          PART II.  OTHER INFORMATION

ITEM 2.  LEGAL PROCEEDINGS

On July 13, 1995, IVD Corporation ("IVD"), a Texas corporation, and Aicesa S.A.
de C.V. ("Aicesa") commenced an action in New York Supreme Court in Erie
County, New York, against the Company's subsidiary Comptek Telecommunications,
Inc. ("CTI"), ARIA Wireless Systems, Inc.  ("ARIA"), and Daniel Dominguez.  IVD
and Aicesa allege that CTI and the other named defendants have defamed the
plaintiffs and thereby injured plaintiffs' business reputation and professional
and other economic interests.  The plaintiffs seek $4,800,000 in actual
damages, in addition to unspecified punitive damages and costs, disbursements,
and attorneys' fees.  The complaint relates to the sale and distribution of
wireless data communications products known as the "DataMover(R)" in Mexico.

Previously, in October 1994, IVD and Aicesa asserted a defamation claim,
together with other breach of contract and tort claims, against CTI and ARIA in
arbitration proceedings before the International Chamber of Commerce seeking
damages in excess of $12,000,000, plus attorneys' fees and costs.  Following a
ruling by the New York Supreme Court, Erie County, in February 1995 that the
alleged defamation was not an arbitrable matter, the plaintiffs withdrew that
count of their request for arbitration, and reduced their asserted damages in
the arbitration proceedings to $7,200,000.

CTI and each of the other defendants have filed respective answers to the
complaint denying all material allegations.  CTI intends to vigorously defend
this lawsuit and believes that the other defendants will also interpose a
vigorous defense.

<PAGE>   12
Currently pending before the United States District Court for the Western
District of New York is a petition by CTI requesting the court to permanently
stay the IVD and Aicesa-initiated arbitration proceedings against CTI.  By
letter dated October 3, 1995, IVD and Aicesa notified the International Chamber
of Commerce that it was dismissing CTI from the arbitration without prejudice,
but would continue to proceed against ARIA.  Shortly thereafter, IVD and Aicesa
filed a motion in U.S. District Court seeking to dismiss CTI's petition as
moot.  CTI intends to oppose this motion and seek a judicial determination to
preclude IVD and Aicesa from any future reinstatement of CTI in the arbitration
proceedings before the International Chamber of Commerce.

The ultimate outcome of these proceedings and their effect, if any, on the
Company's financial position, however, cannot presently be determined.
