ITEM 1.     BUSINESS

GENERAL

            Comptek Research, Inc. (the "Company") is primarily engaged in 
furnishing computer technology related products and services used in information
evaluation and data communications. The Company's operating activities for the
fiscal year ended March 31, 1996 were concentrated in its Defense Electronics
Systems and Services Segment (the "Defense Segment"). Historically and at the
present time, the Defense Segment designs and develops dedicated systems
software and provides technical support for tactical systems, under prime
contracts and subcontracts, for the U.S. Navy and U.S. Air Force. These systems
provide management information and implement offensive and defensive responses
in combat situations. The Defense Segment also builds command, control,
communications and intelligence (C3I) systems. In addition, the Company designs
and develops shipboard and airborne electronic warfare systems and software for
defensive military applications.

            In March 1996, the Company completed an acquisition of a
privately-held developer of simulation, training and software validation systems
related to electronic warfare for domestic and international markets. The
acquired business operates within the Defense Segment as the Advanced Systems
Division (ASD).

            During the first quarter of fiscal 1996, the Company contributed
substantially all of the net assets utilized in the Company's wireless data
communications business to a newly formed Delaware corporation, which continued
to use the ARIA Wireless Systems, Inc. name, in exchange for stock in that
company. The net assets were substantially all of the Commercial Systems and
Services Segment (the "Commercial Segment"). Previously, during fiscal 1995, the
Commercial Segment designed, developed and manufactured wireless data
communication systems that provided seamlessly integrated, complete wireless
solutions for business-critical communications. Additionally, during fiscal
1995, this segment manufactured other commercial electronic products and
provided microwave service.

DEFENSE ELECTRONICS SYSTEMS AND SERVICES

            Modern military operations are dependent upon the effective use of
the electromagnetic spectrum. Radar is a primary military application used for
critical battlefield functions such as target detection, weapons guidance,
communications and intelligence. This has led to the emergence of increasingly
sophisticated and rapidly evolving electronic surveillance and countermeasures,
which are broadly described as "electronic warfare". The reliance of most modern
offensive weapons systems upon radar targeting and guidance has prompted the
development of defensive surveillance systems which rapidly and reliably detect
and identify hostile weapons and weapons platforms, such as ships, submarines,
aircraft or ground installations, by means of their electromagnetic emissions,
and then activate programmed countermeasures, such as jamming, decoys and other
deceptive electronic responses.

            Electronic warfare is a critical factor in warship survivability in
an age of anti-ship missiles. The Company has been a supplier to the U.S. Navy
of surface electronic warfare systems and software since 1973, beginning with
the AN/SLQ-32 software design and development. The AN/SLQ-32 system is the
primary U. S. Navy electronic warfare system and was used on almost every
warship engaged in the Persian Gulf War including cruisers, destroyers and
frigates. The continuing involvement of the Company in the SLQ-32, coupled with
the production of derivative systems, makes the Company a major force in
shipboard electronic warfare.




                                      -5-

<PAGE>   6



            The Company's involvement in airborne electronic warfare includes
production of test and support equipment, and design and development of
operational software. The Company is currently developing software for the U.S.
Navy EA-6B support aircraft. The Company developed several of the critical
signal processing algorithms used for identifying hostile radars quickly, and
has assisted the U.S. and foreign air forces with the development of improved
software for radar warning receivers. This expertise led to design and
production of specialized support and test equipment used in maintaining the
software in modern digital radar warning receivers and jammers.

            In May 1994, the Company was awarded, in effect, a follow-on to the
current Electronic Combat Mission Support (ECMS) contract managed by Comptek
since April 1989. This contract is for support of the Naval Air Warfare Center,
Weapons Division, located in Point Mugu, CA. This cost-plus-fixed-fee contract
represented approximately $18 million in revenues, 33% of total sales, for
fiscal 1996 and has a potential total sales value of more than $70 million
through fiscal 1999.

            In May 1996, Comptek received a one-year contract with two options
totaling $10 million from the Naval Sea Systems Command (NAVSEA). This
cost-plus-fixed-fee program provides to the U.S. Navy engineering support for
its reliability, maintainability and quality assessment. The Company has
provided these types of services to NAVSEA for more than 20 years. Fiscal 1996
sales generated from this contract were approximately $8 million or 15% of total
sales.

            In addition to building systems, the Company in fiscal 1996
continued to be heavily involved in the development of proprietary special
purpose military products. These products are tangible manifestations of
organically evolved niche technologies.

            For over twenty years, the Company has provided a wide range of
technical and engineering services to the U.S. and foreign governments for both
military and non-military applications. Many of these services build on the
Company's knowledge of Command, Control, Communications and Intelligence
("C(3)I"), particularly in regard to the applications of computers for signal
processing, decision support and training.

            The Company acquired Advanced Systems Development Inc., which is
being integrated into the Defense Segment as the Advanced Systems Division
(ASD), on March 1, 1996. As a result of this acquisition, the Company entered
into the Simulation/Stimulation (Sim/Stim) market. ASD specializes in the
design, development, and manufacture of electronic environment simulators and
stimulators for trainers, jammers and radar warning receiver (RWR) evaluation
subsystems. Simulators can replicate battle environments, aircraft cockpits, or
operator stations to provide effective training at costs significantly less than
necessary for large-scale exercises.

COMMERCIAL SYSTEMS AND SERVICES

            Effective May 31, 1995, the Company, along with the other
shareholders of ARIA Wireless Systems, Inc. (old ARIA), completed a transaction
to reorganize and capitalize a new entity by the same name, ARIA Wireless
Systems, Inc. (ARIA), which succeeded to the commercial telecommunications
business of old ARIA. The Company contributed substantially all of the net
assets of its Commercial Segment to ARIA in exchange for stock in that company.
As a result of this transaction, old ARIA was merged into ARIA and all aspects
of engineering, manufacturing, marketing and sale of the DataMover and related
wireless data communications products were consolidated in ARIA. Previously
these activities were split between the Company's commercial subsidiaries and
old ARIA.

            During the third quarter of fiscal 1996, the Company, in view of
ARIA's continuing losses and related financial position, and after reviewing the
Company's related strategic alternatives, charged the full amount of



                                      -6-

<PAGE>   7



its investment in ARIA, together with any amounts then due from ARIA, to
earnings. The amount of this charge including a subsequent fourth quarter
adjustment, was $6,520,000.

            On April 30, 1996, ARIA filed a voluntary petition in the U. S.
Bankruptcy Court for the Western District of New York, under Chapter 11 of the
Bankruptcy Code to reorganize the corporation. The Company, as a principal
shareholder and a creditor of ARIA, intends to submit a proof of claim for all
sums of money due the Company from ARIA and to closely monitor the bankruptcy
proceedings. The ultimate outcome of these proceedings is not expected to have a
material effect on the Company's financial position.

MARKETING

            The Company's military marketing efforts emphasize its substantial
experience and knowledge in the engineering, software development, testing and
evaluation of computer controlled command and control systems and the
sophisticated software which it has developed for electronic warfare systems.
Additionally, as a result of the acquired operations of the ASD, the Company's
international marketing efforts have increased primarily directed towards
Sim/Stim products of the highest commercial quality. These types of commercial
products are considered by the U.S. Navy as commercial off-the-shelf (COTS)
equipment. These Sim/Stim products are priced based on cost, competition and
future customer potential purchases.

            Marketing is conducted primarily by the Company's own marketing,
technical staffs. In many instances, the Company is invited to bid on a contract
by a contracting office or agency of the U.S. Government. Foreign customers are
covered by the Company's direct marketing forces in conjunction with several
in-country representatives.

CUSTOMERS

            During the fiscal year ended March 31, 1996, approximately 97% of
the Company's revenues were attributable to contracts with departments and
agencies of the U.S. Government (including both prime and subcontracts). The
Company's Defense Segment customers include all of the branches of the U. S.
Armed Forces. Its present prime contractor relationships include Vitro, Tracor,
and Raytheon Corp. The remaining 3% of the Company's revenues were attributable
to the operations of ASD for the period March 1, 1996 (acquisition date) through
fiscal year end March 31, 1996. ASD products have been successfully supplied to
departments and agencies of the U.S. Government and to foreign allied military
forces (both include prime and subcontracts). Foreign customers have primarily
been located in Germany, Australia, Italy, and the United Kingdom.

            As discussed above, a major multi-year omnibus contract with the 
U.S. Navy, Naval Air Warfare Center was awarded to the Company in April 1989
(the four-year follow-on was awarded in May 1994) and accounted for 33% of the
Company's revenues for fiscal 1996 and 38% for fiscal 1995. This
cost-plus-fixed-fee contract required the Company to provide electronic combat
mission support (ECMS) to Naval Air Warfare Center, Weapons Division, Pt. Mugu,
California. Management anticipates that this program will continue to be a
major source of revenue in fiscal 1997. The current contract continues through
August 31, 1998. Additionally, the Company contracted with the U. S. Navy,
Naval Sea Systems Command (NAVSEA) for engineering support for its reliability,
maintainability, and quality assessment and represented 15% of the Company's
sales in fiscal 1996 and 13% of sales in fiscal 1995. No other single contract  
accounted for over 10% of the Company's revenues in fiscal 1996.

            In fiscal 1996, approximately 80% of the Company's military-related
revenues were derived from cost-plus-fee contracts, approximately 11% were
derived from fixed-price contracts, and approximately 9% were derived from
time-and-material contracts. On cost-plus-fee contracts, the Company is
reimbursed fully for certain allowable costs and receives a negotiated fee based
on a percentage of these allowable costs. On



                                      -7-

<PAGE>   8



fixed-price contracts, the price is not subject to adjustment by reason of the
cost incurred in the performance of the contract. With these types of contracts,
the Company assumes the risk that it will not perform at a cost below the fixed
price. Under time-and-materials contracts, the Company is paid for the cost of
materials and receives an hourly rate intended to cover salary costs
attributable to work performed on the contract, related overhead expenses, and
an agreed-upon profit margin.

            Substantially all of the Company's U.S. Government contracts
(including both prime and subcontracts) are multi-year contracts which result
from a competitive bidding process. Government contracts contain provisions
permitting termination at any time at the convenience of the Government upon
payment to the Company of costs incurred plus a profit related to the work
performed to date of termination. All of the Company's contracts contain these
provisions. No material adverse adjustments or loss of revenue occurred during
the last fiscal year as a result of early contract termination. The Company, as
a Government contractor, is subject to various statutes and regulations
governing defense contracts generally, certain of which carry substantial
penalty provisions, including denial of future Government contracts. The
Company's books and records are subject to audit by the Defense Contract Audit
Agency. These audits can result in adjustments to contract costs and fees. A
final audit by the Government has been completed through fiscal 1993.

ENGINEERING AND MANUFACTURING

            The Company's technical personnel generally produce the software
sold by the Company and perform the software engineering services; however, from
time to time, the Company engages subcontractors to perform a limited portion of
this work.

            The Company's systems are manufactured from standard hardware
components and items, such as printed circuit boards and fabricated metal parts,
which are built by the Company or to the Company's specifications by various
suppliers. The Company may also use quality commercial equipment referred to as
commercial off-the-shelf for various systems. Computer hardware is purchased, by
the Company, pursuant to standard original equipment manufacturer (OEM) and
Value Added Reseller (VAR) arrangements which enable the Company to obtain
discounts on these products based on the volume it purchases. In some cases, the
customer furnishes the computer hardware which the Company modifies as part of
the project. The Company tries to have multiple sources for all materials and
components. However, due to the advanced nature of some of the Company's
commercial products, chip designs may be available for short periods from only a
single source.

COMPETITION

            The defense industry is dominated by many large companies, all of
whom have much greater resources than the Company. These competitors include
Tracor, Inc., AAI, Inc., Paramax (Unisys), TRW, Inc., Condor Systems, Inc.,
Lockheed Martin Corporation, Computer Sciences Corporation, Raytheon
Corporation, The Boeing Company, and Hughes Aircraft Company. The size and
reputation of many of these companies may give them an advantage in competing
for contracts. The Company also competes with several small companies which can
sometimes take advantage of special government programs such as small business
set asides. The Company on certain contracts has been able to qualify for small
business status when the standard selected is 750 employees or less.

            There is no single company, however, that competes directly with the
Company with respect to all of the Company's major defense market segments. The
Company competes on the basis of the technical expertise of its engineering
staff, and the performance, reliability and price of its products and services.
Government procurement regulations and recent legislation have placed a great
emphasis on competitive procurements. In addition, political pressures directed
at budget reduction are likely to result in keen competition on available
defense industry procurements.

BACKLOG

            The Company's funded backlog and contract backlog of orders at March
31, 1994, 1995, and 1996 were as follows (in thousands):

</TABLE>

         Funded backlog includes commercial orders and contracts with the U.S.
Government, which are incrementally funded by the procuring Government office or
agency. Contract backlog, which includes funded backlog, represents the
aggregate contract revenues remaining to be earned by the Company at a given
time over the life of the contract, whether or not fully funded. Backlog may not
be indicative of net sales in any particular period because of timing
differences associated with receipt of contracts, modifications and extensions.

RESEARCH AND DEVELOPMENT

         The Company, during fiscal year 1996, continued its efforts to develop
and apply new technology. The Company incurred expenditures of $1,308,000,
$2,356,000, and $1,384,000 for R&D activities in fiscal 1996, 1995, and 1994,
respectively. Approximately $640,000 in fiscal 1996 and $502,000 in fiscal 1995
of these expenses are eligible for reimbursement by the Government as
independent research and development (IR&D).

EMPLOYEES

         The Company believes that its continued success will be largely
dependent upon its ability to continue to attract and retain highly trained
professional and technical personnel. As of March 31, 1996, the Company had 661
employees. Their principal areas of expertise include engineering, electronics,
computer technology and management sciences.

PATENTS AND TRADE SECRETS

         The Company currently holds no patents. The Company intends to consider
the benefits of patents as to products which may be developed. The Company's
personnel and various customers, suppliers and consultants are covered by trade
secret agreements and other similar contractual arrangements.

         The Company is restricted in its use of applicable inventions,
processes and proprietary data developed during the performance of U.S.
Government contracts. Depending upon the category of work, (a) the Government
may acquire title and the Company, at a minimum, reserves a non-exclusive,
royalty-free license, (b) the Company may acquire the principal rights and the
Government takes an irrevocable, non-exclusive, royalty-free license, or (c) the
final determination of rights may be made in the best public interest by a
government contracting officer.

ITEM 3.    LEGAL PROCEEDINGS

           In October 1994, IVD Corporation ("IVD"), a Texas corporation, and
Aicesa S.A. de C.V. ("Aicesa"), a Mexico corporation, initiated an arbitration
proceeding in the International Chamber of Commerce relating to a purported
breach of distributorship agreement by ARIA Wireless Systems, Inc. ("ARIA"). The
petition named Comptek Telecommunications, Inc. ("CTI") as a respondent in
addition to ARIA, alleging ARIA was CTI's alter ego or agent. In November 1994,
CTI filed a petition in the United Stated District Court, Western District of
New York, seeking to permanently stay the arbitration against CTI asserting that
CTI was not a signatory to the contract in dispute, nor was ARIA its alter ego
or agent. By letter dated October 3, 1995, IVD and Aicesa notified the
International Chamber of Commerce that is was dismissing CTI from the
arbitration without prejudice, but would continue to proceed against ARIA. On
December 29, 1995, the District Court on motion of IVD and Aicesa dismissed
CTI's petition for injunctive protection as moot and denied CTI's request for a
protective order limiting the use of information obtained by IVD and Aicesa in
the course of discovery related to the petition.




                                      -11-

<PAGE>   12



           On July 13, 1995, IVD Corporation ("IVD"), 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. On April 8, 1996, this action was dismissed with prejudice.

           The Company reached a settlement with M~Wave, Inc. ("M~Wave"), and
its wholly-owned subsidiary, Poly Circuits, Inc. ("Poly Circuits"), 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 settlement
received by the Company included $300,000 in cash and 20,000 shares of M~Wave
stock. Additionally, the Company obtained the right to receive $300,000 in
product at no cost to the Company. The value of this product will be recorded by
the Company if and when the Company exercises this right.

           The Company is involved in various other legal proceedings and claims
which have arisen in the ordinary course of business that have not been finally
adjudicated. These actions when ultimately concluded and determined will not, in
the opinion of management, have a material adverse effect on the Company's
financial position.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

         During fiscal 1996, the Company's operating activities were primarily
concentrated in the Defense Electronics Systems and Services Segment. In this
context, the Company, during the fourth quarter, completed an acquisition of a
niche defense products company, Advanced Systems Development, Inc. (ASDI).
During the third quarter, the Company initiated an intensive review of its
non-operating investment in ARIA Wireless Systems, Inc. (ARIA). As a result of
this review and the financial difficulties encountered by ARIA, the Company's
investment in ARIA was written down to zero. On April 30, 1996, ARIA filed a
voluntary petition in the United Stated Bankruptcy Court under Chapter 11 of the
Bankruptcy Code to reorganize the corporation. The Company will closely monitor
these proceedings in order to maximize the Company's investment position.

<PAGE>   14



FISCAL YEAR 1996 COMPARED WITH FISCAL YEAR 1995

         Transactional activities relating to the Company's Commercial Systems
and Services Segment and its investment in ARIA, had a significant impact on the
Company's fiscal 1996 financial performance. During the first quarter, the
Company, along with the other shareholders of a predecessor corporation
responsible for the marketing and sale of wireless data communication products,
which was also named ARIA Wireless Systems, Inc. (old ARIA), completed a
transaction to reorganize and capitalize ARIA. As a result of this transaction,
old ARIA was merged into ARIA and all aspects of research and development,
engineering, manufacturing, marketing and sale of the DataMover and related
wireless data communications products were consolidated into ARIA. This
transaction affected several aspects of the Company's financial statements as
the Company contributed its remaining Commercial Segment net assets to ARIA in
exchange for stock in that company. Losses associated with the ARIA investment
were $8.98 million in fiscal 1996, and include the Company's equity share of
ARIA's operating losses and the complete write-down of the Company's remaining
investment balance. The Company recorded a similar loss of $1.03 million in
fiscal year 1995 that represented the Company's pro rata share of ARIA's
operating losses during that period.

          Net sales for fiscal 1996 decreased 4.6% from fiscal 1995 to $55.2
million. The elimination of Commercial Segment sales accounted for approximately
half of the total decrease. The capitalization of ARIA during the first quarter
resulted in ARIA as successor to the commercial telecommunications business
activities previously split between Comptek Telecommunications Inc. (CTI), and
old ARIA.

         Delays in subcontractor activity on a U.S. Navy contract for Electronic
Combat Mission Support (ECMS) during the first half of the fiscal year affected
the Defense Electronics Systems and Services Segment's net sales during the
year. This contract represented approximately 33% of the Company's net sales in
1996, compared with 38% in 1995. Total Company backlog at March 31, 1996
increased from the prior year to $62 million, or 11%, primarily due to the
acquisition of ASDI in March 1996. This acquisition is expected to further the
Company's focus on international markets for defense products. On May 2, 1996,
the Company received from the U.S. Navy a contract modification for work
performed on the ECMS contract valued at $26.8 million. The modification
resulted in the Company receiving full funding for the performance period
through August 1998. The Company's backlog, as of May 16, 1996, was
approximately $100 million.

         Gross margins (net sales less cost of sales) increased to 16.8%, from
14.6% in the prior year, primarily due to the current year sales mix. Decreasing
lower margin subcontractor sales on the ECMS contract and the completion of work
earlier than anticipated on a higher margin defense contract, produced overall
higher margins for the year. Additionally, the Commercial Segment, in the prior
year, negatively impacted gross margins.

         The Defense Segment during fiscal 1996 placed greater emphasis on
selling and marketing with a view toward attracting new customers in both
foreign and domestic markets and introducing new proprietary military products.
Accordingly, Selling, General and Administrative expenses (S, G&A), increased
by 17.6% to $7.5 million. Additionally, the Company recorded costs associated
with the reorganization of executive management. S, G&A as a percentage of
sales increased to 14% in fiscal 1996, from 11% in fiscal 1995.

         The first quarter transfer of the Commercial Segment's operations to
ARIA resulted in a decrease of the Company's Research and Development (R&D)
spending. A net reduction in R&D of $1.1 million includes a decrease of $1.5
million in the Commercial Segment, offset in part by an increase of
approximately $400,000 in the Defense Segment. During fiscal 1996 the Defense
Segment concentrated on the development of new proprietary military products and
elected to participate in a Government research and development project.

         Income of $477,000 was recorded, net of associated legal fees, as a 
result of the settlement of litigation between the Company and M~Wave, Inc., and
its wholly-owned subsidiary, Poly Circuits, Inc. (Poly

Circuits). The lawsuit was initiated by the Company against Poly Circuits
seeking compensation for monetary damages incurred as a result of defective
printed circuit boards manufactured for the Company which were 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, Inc. common stock.

         In March 1996, the Company completed an acquisition of ASDI, a
privately-held developer of simulation, training and software validation systems
related to electronic warfare for domestic and international markets. The
acquisition was completed by merger of ASDI into Comptek Federal Systems, Inc.,
a wholly-owned subsidiary of the Company. This transaction was accounted for as
a purchase and, accordingly the assets, liabilities and results of operations
have been consolidated with those of the Company since the acquisition date of
March 1, 1996. The results of operations for the one month ending March 31,
1996, were not material to the Company's consolidated fiscal 1996 financial
results. The Company, however, anticipates that the acquired operations will
have a material impact on the Company's financial results in the future. See
note 11 to the consolidated financial statements for further information.

         Other expense, primarily net interest expense, increased to $218,000 in
fiscal 1996, from $73,000 in fiscal 1995. This increase is due to a higher
average outstanding debt balance, compared with the prior year, coupled with
increases in the LIBOR borrowing rate which have occurred since April 1, 1995.
The Company expects interest expense to increase significantly during fiscal
year 1997 as a result of the increase in long term debt used to finance the
acquisition of ASDI.

         The Company anticipates that the U.S. Department of Defense, the
principal customer group for its Defense Segment, will continue to reduce
overall spending in real dollars. The Company expects this trend to affect
virtually all defense contractors in varying degrees. Additionally, the
Government, specifically DoD, continues to place emphasis on audit and
investigative activities which present risks of unanticipated financial exposure
for companies with substantial activity in Government contract work. The audit
process is an on-going one which includes post-award reviews and audits of
compliance with various procurement requirements. Government regulations provide
that under certain circumstances a contractor may be fined, penalized, have its
progress payments withheld or be debarred from contracting with the Government.
The Company believes that it maintains adequate internal systems to assure
compliance with these requirements and therefore does not anticipate a material
adverse financial impact from the various and on-going procurement reviews. The
DoD also audits the books and records of the Company which can result in
adjustments to contract costs and fees. These audits have been completed for all
fiscal years through 1993, without material adjustments. However, there are no
assurances that future adjustments will not be required.

         The Company's Government contracts are subject to termination at the
Government's convenience, without cause. If a Government contract were
terminated for convenience, the Company would typically, be reimbursed for its
allowable costs to the date of termination and be paid a proportionate amount of
the stipulated profit or fee for the work actually performed. The Company has
not been materially adversely affected by the termination of any government
contract.

FISCAL YEAR 1995 COMPARED WITH FISCAL YEAR 1994

          Net sales declined 8% in fiscal 1995 as a result of the Commercial
Systems and Service Segment's sale of its Industrial Systems Service, Inc. (ISS)
operations and the discontinuation of the Segment's microwave systems and
service business. Both businesses combined represented almost 10% of the
Company's net sales for fiscal 1994. On a comparable basis without ISS and
microwave sales, net sales for the Company increased 1% in 1995 over 1994.




                                      -15-

         The Commercial Segment's wireless data communications sales increased
65% in fiscal 1995 to $1.8 million. Additionally, management was able to resolve
a number of DataMover product performance issues, the most significant of which
resulted from a defective vendor-supplied circuit board. Costs to correct this
defect were $1,153,000, $982,000 of which had been accrued in fiscal 1994.

         The Defense Electronics Systems and Services Segment's sales increased
slightly during fiscal 1995 to $56 million, from $55.5 million in fiscal 1994.
The Defense Segment market continues to expand domestically despite the decline
in DoD spending. In the first quarter of fiscal 1995 a $70 million follow-on
contract for Electronic Combat Mission Support (ECMS) was awarded. This contract
contributed approximately 38% of the Company's net sales in 1995 compared with
36% in 1994. International markets continue to be a focal point as interest in
defense products grows. Total Company backlog at March 31, 1995 was $55.7
million, a 40% increase from the prior year. The increase is primarily the
result of contracts awarded to the Company's Defense Segment.

         The Commercial Segment's disposal and discontinuance of its low margin
businesses, as well as an increase in the Defense Segment's sales of higher
margin contracts, improved the cost of sales as a percentage of net sales during
1995. Cost of sales decreased to 85% of net sales, compared with 88% in 1994.

         The decrease in SG&A for fiscal 1995 is attributable, in part, to the
Company's restructuring efforts. Specifically, the sale of ISS and the microwave
business discontinuance contributed to this decrease. SG&A expense as a
percentage of net sales decreased to 11% in fiscal 1995, from 14% in fiscal
1994.

         Consistent with its focus on product development, the Company increased
R&D spending during 1995 by 70% to $2,356,000, from $1,384,000 in 1994. The
Commercial Segment increased R&D spending by 95%, or $834,000, to $1,716,000.
This increase is primarily due to the development of a new product line which is
an extension of the DataMover technology. The Defense Segment increased R&D
spending by 27%, or $138,000, to $640,000 as a result of increased emphasis on
new products for existing markets.

         During the third quarter, the Commercial Segment completed the sale of
the ISS operations located in Erie, Pennsylvania. This sale was generally in
accordance with the disposal plan adopted in fiscal 1994, except that the sale
occurred approximately six months earlier than expected. The Company received
$1,387,000 in cash and $900,000 in promissory notes. The underlying net assets
of this operation had been included in the assets of business held for sale in
the 1994 Consolidated Balance Sheet. The $4.4 million special charge, recorded
in fiscal 1994, included $1,467,000 for the estimated loss on sale and the
anticipated losses from operations pending the completion of the sale. The
Company recorded a $331,000 reversal of this charge in the third quarter of
fiscal 1995 to reflect the final accounting for the sale.

         Other expense, primarily net interest expense, decreased in fiscal 1995
to $73,000, from $266,000 in fiscal 1994. The decrease was a result of a lower
average outstanding balance on the Company's credit facility as positive cash
flow was used to reduce debt. Additionally, interest income was received on
outstanding notes receivable.

         The Company recorded a loss for its minority share in the Company's
investee, old ARIA of $1,033,000 for 1995 compared with a loss of $116,000 for
1994. Beginning with the fiscal 1995 fourth quarter, when old ARIA began to
generate a stockholders' deficiency, the Company as its most significant
economic stakeholder began to record 100% of old ARIA's operating results as
equity in net loss. Fiscal 1995 losses were primarily attributable to lower than
anticipated sales, increased domestic and international marketing efforts,
settlement of litigation, and establishment of reserves for accounts receivable.
The Commercial Segment's sales to old ARIA during fiscal 1995 were $1,196,000
compared to $1,123,000 in the prior year. Total due from old ARIA was $2,350,000
(including loans and accounts receivable) at March 31, 1995.

LIQUIDITY AND CAPITAL RESOURCES

         The Company reported positive cash flow from operations in fiscal 1996
of $814,000, a $374,000 increase from the prior year of $440,000, and a decrease
when compared with fiscal year 1994 of $1,477,000. Increases in receivables and
inventories were significant uses of cash during the year, while other current
assets provided cash. Inventory increases are directly related, to the
Commercial Segment activities through May 31, 1995, when substantially all of
the Commercial Segment's net assets were contributed as a part of the ARIA
combination. Receivable increases are associated with the Defense Segment and
the increase in sales during the fourth quarter of fiscal 1996.

         The Company funded the operations of the Commercial Segment through May
31, 1995. The Company also provided operating cash to ARIA through the purchase
of senior subordinated notes totaling $1,827,000. Expenditures for equipment and
leasehold improvements decreased to $889,000 in the current year. This reduction
was primarily due to the Commercial Segment and ARIA combination. The Company
received cash as a result of the settlement of litigation and the principal
payments on a note receivable taken in the sale of Industrial Systems Services,
Inc., Erie operations.

         The Company acquired ASDI, effective March 1, 1996, and used
approximately $370,000 in cash and acquired cash of approximately $69,000. In
connection with the acquisition, the Company established a new credit facility
with its current lender which consists of a $5,000,000 five year term loan used
to reduce ASDI's existing financing facility and a $10,000,000 revolving credit
agreement. The Company, at March 31, 1996, had $3,500,000 outstanding on the
revolving credit facility, compared to $2,100,000 at March 31, 1995. The Company
used financing available under its facility to fund the cash requirements for
the fiscal year noted above. Accordingly, the Company's total debt to equity
ratio increased to 2:1 at March 31, 1996, from .9:1 at March 31, 1995. Also,
affecting this ratio is the decrease in equity due to the losses recorded as a
result of the write-down of the ARIA investment. The Company anticipates the
cash flows from operations and available borrowing capacity will be sufficient
to cover working capital, capital expenditure demands and the repayment of long
term debt in the coming year.

RECENT ACCOUNTING PRONOUNCEMENTS

         Statement of Financial Accounting Standards (SFAS) No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of, and SFAS No. 123, Accounting for Stock-Based Compensation are
required to be adopted in fiscal 1997. The Company's policy on impairment is
not materially different than that prescribed by SFAS 121. As permitted by SFAS
123, the Company will continue to apply its current accounting policy under
Accounting Principles Board Opinion No. 25 and will include the necessary
disclosures in the 1997 financial statements.

INFLATION

         Inflation has, and continues to have, minimal effect upon the Company's
results. Where competitive conditions and government regulations permit, the
Company seeks to reduce the potential impact of inflation by negotiating price
escalations into contracts.

COMPTEK RESEARCH, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 1996, 1995 and 1994

(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
================================================================================

(a)   CONSOLIDATION
The consolidated financial statements include the accounts of Comptek Research,
Inc. and its wholly-owned subsidiaries (the Company). All significant
intercompany balances and transactions are eliminated in consolidation.

(b)   REVENUE RECOGNITION
The Company's operations consist of furnishing computer-technology-related
products and services used in information evaluation and data communications.

The Defense Electronics Systems and Services Segment generally provides computer
software and hardware to the U.S. Government under prime contracts and
subcontractual arrangements. Costs are accumulated for each contract with
uncompleted contracts, at the balance sheet dates, recorded on a
percentage-of-completion basis whereby costs and estimated earnings are deemed
sales based on estimates as the work is performed. Certain contracts have terms
extending beyond the Company's financial reporting year. Revisions in costs and
estimated earnings are reflected in the year when the additional data becomes
known. Estimated losses on contracts are recorded as identified.

Sales of commercial products are recorded upon shipment.

(c)   CASH EQUIVALENTS
Cash equivalents consist of liquid, short-term investments with an original
maturity of three months or less.

(d)   INVENTORIES
Inventories are stated at the lower of cost (first-in, first-out) or market (net
realizable value).

(e)   EQUIPMENT AND LEASEHOLD IMPROVEMENTS
Depreciation is recorded on the straight-line method over the estimated useful
lives of the assets. Machinery and equipment and furniture and fixtures are
depreciated over estimated useful lives of five to ten years. Improvements to
leased property are depreciated over the lesser of the life of the lease or the
life of the improvement.

(f)   INTANGIBLE ASSETS ARISING FROM BUSINESS ACQUISITIONS
These assets, consisting of the excess of cost over the fair value of assets
acquired, are carried at the lower of cost or net realizable value, and are
amortized on the straight-line method over the period of estimated benefit,
generally ranging from 15 and 20 years. Net realizable value of intangibles is
determined based on the projected undiscounted future operating cash flows of
the underlying business. The assessment of the recoverability of intangibles
will be impacted if estimated future operating cash flows are not achieved.

(g)   INVESTMENT IN EQUITY AFFILIATE
Given ARIA's financial and operational status, the Company, during fiscal 1996,
fully wrote-down its investment in ARIA (note 12). Previously, the Company used
the equity method of accounting and, when ARIA's cumulative losses exceeded its
contributed capital, recorded 100% of ARIA's losses as equity in loss, as the
Company was ARIA's principal investor.




                                      -22-

<PAGE>   23



(h)   INCOME TAXES
Deferred tax assets and liabilities are provided on temporary differences
between the book and tax basis of assets and liabilities and for net operating
loss and credit carryforwards. Deferred taxes are adjusted at each balance sheet
date to the amounts expected to be paid or received in the future, based upon
current tax laws. The tax effects of deductions attributable to employees'
disqualifying dispositions of shares obtained from incentive stock options are
reflected in additional paid-in capital.

(i)   FAIR VALUE OF FINANCIAL INSTRUMENTS
The estimated fair value of all financial instruments approximate their carrying
amounts in the balance sheet.


(j)   USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
related to the reporting of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

(k)   SHARE DATA
Earnings per share data are based on the weighted average number of shares of
common stock and dilutive common stock equivalents outstanding during the year.

(l)   RECLASSIFICATION
Certain reclassifications have been made to the 1995 and 1994 consolidated
financial statements to conform to the 1996 presentation.


(2)   RECEIVABLES
- --------------------------------------------------------------------------------

Receivables consist of:

Unbilled contract receivables are comprised primarily of amounts of revenue
recognized on contracts for which billings have not been presented under the
terms of the contracts at the balance sheet dates. It is anticipated that such
unbilled amounts at March 31, 1996, will be received upon presentment of
billings or completion of contracts. Substantially all unbilled amounts are
expected to be collected within one year. On March 31, 1996, $12.6 million of
receivables were from U.S.

In May 1995, the Company contributed net assets with a book value of
approximately $7 million to ARIA in connection with its recapitalization. As a
result of ARIA's continuing losses, and the Company's intense review of its
strategic alternatives with respect to ARIA, the Company fully wrote-down its
investment in ARIA during fiscal 1996 (note 12).

</TABLE>

The Company, as a result of the acquisition of Advanced Systems Development,
Inc. (ASDI) (note 11), established a new credit facility with its lender which
consists of a maximum borrowing line of $10,000,000 under a revolving credit
agreement and a five year term loan of $5,000,000, both secured by substantially
all of the Company's assets.

(a)    The revolving credit agreement provides for interest at the prime rate
       plus 1/4% or 2.50% above LIBOR (at the Company's option) and a fee of
       1/4% of any unused portion of the line. Borrowings under this agreement
       mature March 31, 1998, at which time the Company has the option to
       convert the borrowings into a four year term loan, with principal and
       interest payable monthly at prime plus 1/2%.

(b)    The five year term loan provides for interest at 8.5%, with principal and
       interest payable monthly and matures on March 31, 2001.

Both agreements, among other things, stipulate that the Company maintain minimum
levels of working capital and tangible net worth, not exceed certain prescribed
levels of capital expenditures and prohibits the payment of cash dividends.

Total interest expense was $260,000, $138,000 and $266,000 in 1996, 1995 and
1994, respectively.

Assuming conversion of the revolving credit note to term debt, the maturities of
long-term debt at March 31, 1996 are: $1,051,000 in 1997, $1,126,000 in 1998,
$1,929,000 in 1999, $1,892,0000 in 2000, $1,875,000 in 2001, and $804,000
thereafter.

(7)    SHAREHOLDERS' EQUITY
- --------------------------------------------------------------------------------

Pursuant to the Company's Equity Incentive Plan, options to purchase shares have
been granted to certain key employees. The Company may award up to 948,000
shares in the form of stock options, restricted stock, performance shares and
other equity awards under this plan. Through March 31, 1996, stock options and
equity awards related to incentive compensation have been issued pursuant to
this plan.



                                      -25-

All options are exercisable at a price not below market at date of grant, have a
term of ten years and become exercisable in either equal quarterly or equal
annual increments over a period of one to five years. During 1996, options to
purchase 58,726 shares became exercisable. Options for 188,680 shares were
exercisable at March 31, 1996.

</TABLE>


During fiscal 1996, $340,000 in deferred tax liabilities were transferred to
ARIA in connection with the combination of the Company's commercial
telecommunications business and ARIA (note 12). Of the remaining change in net
deferred tax assets, $183,000 was charged to operations and $12,000 was credited
directly to shareholders' equity as a result of the tax benefit of disqualifying
option exercises.

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will be realized. Management primarily considers the effect of taxable
temporary differences and projected future earnings in making this assessment.

At March 31, 1996, the Company's net operating loss carryforward ($3,189,000 of
Federal and $827,000 of state) expires from 2009 to 2010. The general business
credits of $614,000 expire from 2004 to 2012. The Company also has $220,000 of
alternative minimum tax credit carryforwards available with no expiration date.


(10)  LEASE COMMITMENTS
- --------------------------------------------------------------------------------

The Company conducts its operations from leased facilities and uses certain
equipment primarily under operating lease arrangements. All leases expire prior
to the year 2002. Real estate taxes, insurance and maintenance expenses are
obligations of the Company. It is expected that in the normal course of
business, leases that expire will be renewed or replaced. Total rental expense
was $1,439,000 in 1996, $1,594,000 in 1995, and $1,816,000 in 1994.

(11)   ACQUISITION
- --------------------------------------------------------------------------------

Effective March 1, 1996, the Company acquired all of the outstanding stock of
ASDI, a privately-held developer of simulation, training and software validation
systems for electronic warfare which were sold into both domestic and
international markets. The purchase price consisted of $369,843 in cash,
forgiveness of a note of $22,019 and 623,892 shares of the Company's common
stock. If the average market value of the Company's common stock falls below
$5.08 for the thirty day period prior to March 7, 1997, the Company will be
required to pay such shortfall on 623,892 shares, to the former stockholders of
ASDI in either cash or stock.

The acquisition was accounted for as a purchase and the excess of purchase price
over the estimated fair value of net assets acquired was approximately
$4,574,000 and is being amortized on a straight-line basis over 20 years (note
5). Because information required to determine the estimated fair value of all of
the net assets is incomplete at this time, management's estimates may differ
from the final allocation. The consolidated financial statements include the
operations of ASDI from March 1, 1996.

The following unaudited pro forma results of operations for the years ended
March 31, 1996 and 1995 assumes the ASDI acquisition occurred as of the
beginning of each of the periods:

(12)   INVESTMENT IN EQUITY AFFILIATE
- --------------------------------------------------------------------------------

Effective May 31, 1995, the shareholders of ARIA, including the Company,
completed a transaction to reorganize and capitalize a new entity, which
continued to use the ARIA Wireless Systems, Inc. name. The Company contributed
approximately $7 million of net assets to ARIA in connection with this
transaction.




                                      -29-

<PAGE>   30



During the third quarter of fiscal 1996, the Company, after considering ARIA's
continuing losses and financial condition, and after reviewing the Company's
related strategic alternatives, charged the full amount of its investment in
ARIA, together with any amounts then due from ARIA, to earnings. The amount of
this charge, including additional fourth quarter adjustments, was $6,520,000 and
has been included in the loss associated with ARIA on the 1996 Consolidated
Statements of Operations. In addition, on April 30, 1996, ARIA filed a voluntary
petition under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy
Court for the Western District of New York. The Company, through certain of its
subsidiaries, is a principal shareholder and a creditor of ARIA. The Company
intends to submit a proof of claim for all sums of money due the Company from
ARIA and to closely monitor the bankruptcy proceedings. The ultimate outcome of
these proceedings is not expected to have a material effect on the Company's
financial position.


(13)     LEGAL PROCEEDINGS
- --------------------------------------------------------------------------------

In October 1994, IVD Corporation ("IVD"), a Texas corporation, and Aicesa S.A.
de C.V. ("Aicesa"), a Mexico corporation, initiated an arbitration proceeding in
the International Chamber of Commerce relating to a purported breach of
distributorship agreement by ARIA Wireless Systems, Inc. ("ARIA"). The petition
named Comptek Telecommunications, Inc. ("CTI") as a respondent in addition to
ARIA, alleging ARIA was CTI's alter ego or agent. In November 1994, CTI filed a
petition in the United Stated District Court, Western District of New York,
seeking to permanently stay the arbitration against CTI asserting that CTI was
not a signatory to the contract in dispute, nor was ARIA its alter ego or agent.
By letter dated October 3, 1995, IVD and Aicesa notified the International
Chamber of Commerce that is was dismissing CTI from the arbitration without
prejudice, but would continue to proceed against ARIA. On December 29, 1995, the
District Court on motion of IVD and Aicesa dismissed CTI's petition for
injunctive protection as moot and denied CTI's request for a protective order
limiting the use of information obtained by IVD and Aicesa in the course of
discovery related to the petition.

On July 13, 1995, IVD Corporation ("IVD"), a Texas corporation, and Aicesa S.A.
de C.V. ("Aicesa"), a Mexico corporation, 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. On April 8, 1996, this action was
dismissed with prejudice.

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 settlement received by the Company
included $300,000 in cash and 20,000 shares of M~Wave stock. Additionally, the
Company obtained the right to receive $300,000 in product at no cost to the
Company. The value of this product will be recorded by the Company if and when
the Company exercises this right. The settlement income is included in the 1996
special credit.

The Company is involved in various other legal proceedings and claims which have
arisen in the ordinary course of business that have not been finally
adjudicated. These actions when ultimately concluded and determined will not, in
the opinion of management, have a material adverse effect on the Company's
financial position.


(14)    SPECIAL CHARGE
- --------------------------------------------------------------------------------

The 1994 special charge includes $1,467,000 for the anticipated loss on disposal
of a subsidiary. The disposal occurred in fiscal 1995 at a final loss which was
$331,000 less than that provided for in 1994. The 1994 special charge also
includes $1,877,000 for warranty cost associated with faulty vendor-supplied
printed circuit boards and $1,089,000 for the discontinuation of its microwave
services business. The warranty matter resulted in a claim against the vendor
which was resolved in 1996 (note 13).

(15)  SEGMENT INFORMATION
- --------------------------------------------------------------------------------


The Company contributed substantially all of the operating assets of its
Commercial Systems and Service Segment to ARIA on May 31, 1995 (note 12).
Accordingly, during fiscal 1996, the Company operated principally in one
industry segment, Defense Electronics Systems and Services.

Prior to fiscal 1996, the Company reported information for two principal
industry segments: (1) Defense Electronics Systems and Services, and (2)
Commercial Systems and Services. The Defense Electronics Systems and Service
Segment provides electronic warfare and battle management systems to the U.S.
Department of Defense and allied military services. This Segment held contracts
with the U.S. Navy, Naval Air Systems Command for Electronic Combat Missions
Systems (ECMS) which contributed 33% of sales in 1996, 38% in 1995 and 36% in
1994. The Defense Segment also held contracts with the U.S. Navy, Naval Sea
Systems Command (NAVSEA) which accounted for 15% of sales in 1996, 13% in 1995
and in 1994. No other single customer accounted for more than 10% of sales
during such periods. The Commercial Systems and Service Segment provided
wireless data communications products and services to the financial industry and
other commercial customers throughout the world.

Corporate, general and administrative costs were allocated to each segment on a
pro rata basis.

                          INDEPENDENT AUDITORS' REPORT

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



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

       We have audited the accompanying consolidated balance sheets of Comptek
Research, Inc. and subsidiaries as of March 31, 1996 and 1995, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the years in the three-year period ended March 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

       We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

       In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Comptek
Research, Inc. and subsidiaries at March 31, 1996 and 1995, and the results of
their operations and their cash flows for each of the years in the three-year
period ended March 31, 1996, in conformity with generally accepted accounting
principles.

          Independent Auditors' Report on Financial Statement Schedules
          -------------------------------------------------------------





The Board of Directors
Comptek Research, Inc.:

Under date of May 14, 1996, we reported on consolidated balance sheets of
Comptek Research, Inc., and subsidiaries as of March 31, 1996 and 1995, and the
related consolidated statements of earnings, shareholders' equity and cash flows
for each of the years in the three-year period ended March 31, 1996. In
connection with our audits of the aforementioned consolidated financial
statements, we also have audited the related financial statement schedule as
listed in item 14(a)(2) of this annual report on Form 10-K. This financial
statement schedule is the responsibility of the Company's management. Our
responsibility is to express an opinion on this financial statement schedule
based on our audit.

In our opinion, such financial statement schedule, when considered in relation
to the basic consolidated financial statements taken as a whole, presents
fairly, in all material respects, the information set forth therein.

                             COMPTEK RESEARCH, INC.
                UNDER SECTION 805 OF THE BUSINESS CORPORATION LAW


         WE, THE UNDERSIGNED, William K. LaSala and Christopher A. Head, being 
respectively the President and the Secretary of Comptek Research, Inc. (the

         1. The name of the Corporation is Comptek Research, Inc.

                                      -1-
<PAGE>   11



                  (A) The Preferred Shares authorized hereby may be issued (i)
in such series and with such voting powers, full or limited, or no voting
powers, and such designations, preferences and relative, participating, optional
or other special rights, and with such qualifications, limitations or
restrictions thereon, as the Board of Directors shall fix by resolution, and
(ii) in such number of shares in each series as the Board of Directors, by
resolution or resolutions, shall fix; provided that the aggregate number of all
Preferred Shares issued does not exceed the number of Preferred Shares
authorized hereby.

                  (B) Holders of Common Shares shall be entitled to such
dividend, liquidation and voting rights and such other rights and privileges as
are provided by the Business Corporation Law, subject to the rights of holders
of Preferred Shares issued pursuant to the provisions of paragraph (A) above.

         B. Paragraph FIFTH of the Certificate of Incorporation which sets forth

                  110 Broadway
                  Buffalo, NY    14203

                  Attn:    The President

         C. A new paragraph EIGHTH of the Certificate of Incorporation is hereby
added to read as follows:


EIGHTH: The business and affairs of the Corporation shall be managed by a Board
of Directors consisting of not less than six (6) persons. The exact number of
directors shall be fixed from time to time by the Board of Directors pursuant to
a resolution adopted by the affirmative vote of a majority of the entire Board


                                      -2-

<PAGE>   12

of Directors. As used in this Certificate of Incorporation, the term "entire
Board of Directors" means the total authorized number of directors which the
Corporation would have if there were no vacancies.

         (A) At the 1986 Annual Meeting of Shareholders, the directors shall be
divided into three classes, as nearly equal in number as possible, with the term
of office of the first class to expire at the 1987 Annual Meeting of
Shareholders, the term of office of the second class to expire at the 1988
Annual Meeting of Shareholders and the term of office of the third class to
expire at the 1989 Annual Meeting of Shareholders. Commencing with the 1987
Annual Meeting of Shareholders, directors elected to succeed those directors
whose terms have thereupon expired shall be elected for a term of office to
expire at the third Annual Meeting of Shareholders after their election.

         (B) If the number of directors is increased to nine or more, the
directors shall be divided into three classes at the next succeeding Annual
Meeting of Shareholders following such increase, with each class to consist of
at least three directors and the difference in the number of directors in any
two classes not to exceed one. If necessary, one director from the class whose
term does not expire at the next succeeding Annual Meeting of Shareholders, to
be nominated pursuant to a resolution adopted by the affirmative vote of a
majority of the entire Board of Directors, will be elected for a term of office
to expire at the second succeeding Annual Meeting of Shareholders after his
election so as to ensure that each class will consist of at least three
directors. Thereafter, directors elected to succeed those directors whose terms
have thereupon expired shall be elected for a term of office to expire at the
third succeeding Annual Meeting of Shareholders after their election. If the
number of directors is decreased to eight or less, the directors shall be
divided into two classes at the next succeeding Annual Meeting of Shareholders,
with both classes to consist of at least three directors and the difference in
the number of directors in both classes not to exceed one, but in no case will
the decrease in the number of directors shorten the term of any incumbent
director. Thereafter, directors elected to succeed those directors whose terms
have thereupon expired shall be elected for a term of office to expire at the
second succeeding Annual Meeting of Shareholders after their election. Any
increase or decrease in the number of directors which does not cause a change in
the number of classes shall be 


                                      -3-

<PAGE>   13

apportioned among the classes so as to maintain or attain, if possible, the
equality of the number of directors in the classes, but in no case will a
decrease in the number of directors shorten the term of any incumbent director.
If such equality is not possible, the increase or decrease shall be apportioned
among the classes in such a way that the difference in the number of directors
in any two classes shall not exceed one.

         (C) Subject to the rights of the holders of any series of Preferred
Stock or any other class of capital stock of the Corporation (other than the
Common Stock) then outstanding, vacancies in any class of directors resulting
from death, resignation, retirement, disqualification, removal from office or
other cause shall, if occurring prior to the expiration of the term of office of
such class, be filled only by the affirmative vote of a majority of the
remaining directors of the entire Board of Directors then in office, although
less than a quorum, or by the sole remaining director. Any director so elected
shall hold office until the next Annual Meeting of Shareholders and until his
successor is elected and qualified.

         (D) Whenever the holders of any one or more series of Preferred Stock
issued by the Corporation shall have the right, voting separately by series, to
elect directors at an annual or a special meeting of shareholders, the election,
term of office, filling of vacancies and other features of such directorships
shall be governed by this Paragraph 8 unless expressly otherwise provided by the
resolution or resolutions providing for the creation of such series.

         (E) Subject to the rights of holders of any series of Preferred Stock
or any other class of capital stock of the Corporation (other than the Common
Stock) then outstanding, (i) any director, or the entire Board of Directors, may
be removed by the shareholders from office at any time prior to the expiration
of his term of office, but only for cause, and only by the affirmative vote of
the holders of record of outstanding shares representing a majority of the
voting power of all of the outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors, and (ii)
any director may be removed from office by the affirmative vote of a majority of
the entire Board of Directors, at any time prior to the expiration of his term
of office, but only for cause.


                                      -4-

<PAGE>   14

         (F) Notwithstanding any other provision of this Certificate of
Incorporation and subject to the other provision of this Paragraph 8, the Board
of Directors shall determine the rules and procedures that shall affect the
directors' power to manage and direct the business and affairs of the
Corporation. Without limiting the foregoing, the Board of Directors shall
designate and empower committees of the Board of Directors, shall elect and
empower the officers of the Corporation, may appoint and empower other officers
and agents of the Corporation, and shall determine the time and place of, and
the notice requirements for, Board meetings, as well as quorum and voting
requirements for, and the manner of taking, Board action, and no By-Law shall be
adopted by shareholders which shall modify the foregoing.

         (G) The affirmative vote of the holders of record of outstanding shares
representing at least eighty percent (80%) of the voting power of all of the
outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors shall be required to amend, alter or
repeal, or adopt any provision or provisions inconsistent with, any provisions
of this Paragraph 8 including this subparagraph (G); provided, however, that
this subparagraph (G) shall not apply to, and such eighty percent (80%) vote
shall not be required for, any amendment, alteration, repeal or adoption of any
inconsistent provision or provisions, declared advisable by the Board of
Directors by the affirmative vote of two-thirds of the entire Board of
Directors.

         D. A new paragraph NINTH of the Certificate of Incorporation is hereby
added to read as follows:

NINTH:  (A) In addition to any affirmative vote required by law or this 
Certificate of Incorporation, and except as otherwise expressly provided in
paragraph (B) of this paragraph 9,

defined) of $4,000,000 or more, or

                  (iii) the issuance or transfer by the Corporation or any
Subsidiary (in one transaction or a series of transactions) or any securities of
the Corporation or any Subsidiary, or both, to (a) an Interested Shareholder or
(b) any other person (whether or not itself an Interested Shareholder) which is,
or after such issuance or transfer would be, an Affiliate or Associate of an
Interested Shareholder in exchange for cash, securities or other property (or a
combination thereof) having an aggregate Fair Market Value of $4,000,000 or
more, other than the issuance of securities upon the conversion of convertible
securities of the Corporation or any Subsidiary which were not acquired by such
Interested Shareholder (or such Affiliate or Associate) from the Corporation or

stock split), or recapitalization of the Corporation, or any merger or
consolidation of the Corporation with any of its Subsidiaries or any other

person (whether or not itself an Interested Shareholder) which is, or after such

fiduciary obligation imposed by law.

         (F) The fact that any Business Combination complies with provisions of
subparagraph ("C") of this Paragraph 9 shall not be construed to impose any
fiduciary duty, obligation or responsibility on the Board of Directors, or any
member thereof, to approve such Business Combination or recommend its adoption
or approval to the shareholders of the Corporation, nor shall such compliance
limit, prohibit or otherwise restrict in any manner the Board of Directors, or

any inconsistent provision or provisions, declared advisable by the Board of
Directors by the affirmative vote of two-thirds of the entire Board of Directors

Board of Directors of Comptek Research, Inc. acting by unanimous written consent
dated June 11, 1986.

                 4.       FRANK J. PERPIGLIA.  Except to the extent it is
otherwise provided in this Agreement and in consideration of the covenants made
in this Agreement, the Employee hereby releases and waives any and all claims
the Employee now has, ever had, can or shall have against the Corporation, its
employees, officers and directors, whether known or unknown, including based
upon any facts that may be discovered subsequent to the date of this Agreement,

and irrevocably agrees to indemnify and hold the Employee free and harmless
against all claims, liabilities, damages, losses, costs and expenses (other
than with respect to personal income taxes) incurred by the Employee, including
the reasonable fees and expenses of attorneys, accountants and investigators of
any claim, or threatened claims, or the defense of any suits and/or
proceedings, relating to or arising, directly or indirectly, out of the

claim, for which the Employee seeks indemnification under this Agreement, the
Corporation shall have the reasonable right to (i) direct the defense of such
claim, (ii) select counsel, and (iii) settle the claim on such terms as the
Corporation deems appropriate.  Anything contained in this Agreement to the
contrary notwithstanding, the Corporation shall not be liable under this
Agreement to make any payment in connection with any such indemnified claim
made against the Employee to the extent the Employee has already received
payment or some other person or entity has on behalf of the Employee already
remitted payment of the amount otherwise indemnifiable hereunder.

Agreement constitutes the entire agreement of the parties hereto with respect
to the subject matter hereof and supersedes any and all prior agreements or
understandings, both written and oral, among the parties with respect to such
subject matter.  Any amendment or modification of this Agreement shall be

                             COMPTEK RESEARCH, INC.

                                JOHN R. CUMMINGS


         THIS AMENDMENT, made as of the 31st day of March 1996, by and between
JOHN R. CUMMINGS, residing at 43 Hemlock Hill, Orchard Park, New York, 14127,
("Employee") and COMPTEK RESEARCH, INC., a New York Corporation having its
office and principal place of business at 2732 Transit Road, Buffalo, New York
14224 (the "Corporation").

                                  WITNESSETH:

         WHEREAS, Employee and the Corporation entered into an Employment
Agreement dated April 1, 1994 (the "Employment Agreement"); and

         WHEREAS, Employee and the Corporation wish to amend such Employment
Agreement, (the "Amendment to Agreement") as provided for herein;

          NOW, THEREFORE, in consideration of the mutual covenants and
obligations contained herein, the parties hereto agree as follows:

         1.    TERM OF EMPLOYMENT.  The Employee's term of employment by the
Corporation as its President and Chief Executive Officer shall be deemed to end
as of the date hereof.  The Employee shall continue as the Corporation's
Chairman of the Board of Directors.

         2.    DUTIES AND RESPONSIBILITIES.  Effective April 1, 1996, Employee
shall no longer have responsibility for the executive management of the
Corporation and its affairs.  Employee





\AGR\AMEND96.JRC                        -1-
<PAGE>   3
shall act as the Corporation's Chairman of the Board of Directors and have such
duties and responsibilities as may be assigned to the Chairman in accordance
with the Corporation's by-laws and resolutions adopted by the Board of
Directors.  Employee shall no longer be required to devote his full business
time to the promotion of the business of the Corporation, but will continue to
provide valuable skills and services to the Corporation.

         3.    COMPENSATION.  Effective April 1, 1996, Employee shall be deemed
to be a non-employee Director of the Corporation and be entitled to all
compensation and benefits from time to time provided to non-employee directors
of the Corporation.  The Corporation shall pay to Employee a Base Salary of not
less than $135,000 for the period April 1, 1996 through December 31, 1996,
payable in approximately equal installments at such intervals as the
Corporation pays the salaries of its executive employees generally.  On January
1, 1997, and on the first day of each month thereafter through March 1, 1998,
the Corporation shall pay to Employee the amount of $15,000 per month in
consideration for his non-competition with the Corporation.

         4.    BENEFITS AND EXPENSES.  Employee will be entitled to
reimbursement for all reasonable travel and other business expenses incurred by
him in connection with services by him to the Corporation.  Employee will be
included in any group medical, dental, and life insurance plans which the
Corporation may have in force from time to time for its executive personnel
through March 31, 1998.  If Employee cannot be included under the terms of such
plan because of a change in his employment status, then the Corporation shall
provide to Employee a substantially equivalent plan or benefit in lieu thereof.
Such medical, dental, and life insurance benefits and any resulting payments
thereunder, shall be in addition to his Base Salary and shall include any
additional amount as may be necessary to provide the Employee with the
after-tax equivalent of such Benefits as provided to executives of the
Corporation.  Except as expressly set forth in this Amendment to Agreement, and
vacation accrued prior to April 1, 1996, there will be no other benefits or
cash payments to Employee pursuant to the Employment Agreement dated April 1,
1994, including, but not limited to incentive compensation.

<PAGE>   4
         5.    DEATH OR DISABILITY.  In the event of the Employee's death or
disability, the Corporation shall continue to be obligated to make the payments
provided for in this Amendment to Agreement to the Employee or his estate, as
the case may be.

         6.    NON-COMPETITION AND NON-SOLICITATION.  The time periods provided
for in paragraphs 6 (Non-Competition) and 9 (Non-Solicitation and
Non-Interference) of the Employment Agreement are hereby amended to continue in
full force in effect through March 31, 1998.

         7.    GENERAL.  Except to the extent amended by this Amendment to
Agreement or in a conflict with the Amendment to Agreement, the Employment
Agreement shall continue in full force and effect.  In the event of any
conflict between the terms of the Employment Agreement and this Amendment to
Agreement, then this Amendment to Agreement shall govern.

         IN WITNESS WHEREOF, Employee has hereunto set his hand and seal, and
the Corporation has caused these presents to be executed by a duly authorized
officer of the Corporation and its corporate seal to be affixed hereto, the day
and year first above written.

Portion, the Borrower shall have the option of repaying the outstanding
principal amount of any Revolving Loan to the Bank in advance in full or part
at any time and from time to time without any premium or penalty.

                 e.       INTEREST.  From and including the date the first
Revolving Loan is made to but not including the date the outstanding principal
amount of each Revolving Loan is repaid in full, the Borrower shall pay to the
Bank interest, calculated on the basis of a 360-day year for the actual number
of days of each year (365 or 366, as applicable), on the aggregate outstanding
principal amounts of all Revolving Loans at a rate per year that shall (i) on
each day beginning before the maturity, whether by acceleration or otherwise,

rounded, if necessary, to the next higher .0625%, that is the rate obtained by
dividing (I) the total of (1) the Applicable Margin and (2) the Libor Rate for
such Libor Rate Period by (II) expressed as a decimal, the difference between
100% and the maximum percentage of reserve requirement (including any
emergency, supplemental or other marginal percentage of reserve requirement)

Bank's Prime Rate; provided, however, that (1) such interest shall not be
charged as provided in clause (i)(B) of this sentence with respect to any Libor
Rate Portion if before the Libor Rate Period Commencement Date on which the
Libor Rate Period for such Libor Rate Portion begins (a) any Governmental
Authority asserts that it is unlawful, or the Bank determines that it is
unlawful, for the Bank to charge interest on such Libor Rate Portion at a rate
determined by reference to the Libor Rate, (b) the Bank determines that United
States dollar deposits in immediately available funds are not available for
such Libor Rate Period to the Bank or any participant in such Libor Rate
Portion to the extent of its interest in such Libor Rate Portion or (c) the
Bank determines that information

necessary to determine the rate to be charged pursuant to such clause (i)(B) is
unavailable, (2) such interest shall cease to be charged as provided in such

Authority asserts that it is unlawful, or the Bank determines that it is
unlawful, for the Bank to continue to charge interest on such Libor Rate
Portion at a rate determined by reference to the Libor Rate, (3) in no event
shall such interest be payable at a rate in excess of the maximum rate
permitted by applicable law and (4) solely to the extent necessary to result in
such interest not being payable at a rate in excess of such maximum rate, any
amount that would be treated as part of such interest under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled and, if received by the Bank, shall be refunded to the
Borrower, it being the intention of the Bank and the Borrower that such
interest not be payable at a rate in excess of such maximum rate.  Except as
otherwise provided in Section 2c of this Agreement, (i) a payment of such
interest shall become due on the first day of each calendar month, beginning on
the first day of the first calendar month following the calendar month in which
the first Revolving Loan is made, except for any of such interest payable with
respect to any Libor Rate Portion, and (ii) all of such interest payable with
respect to any Libor Rate Portion shall become due on the day after the last
day in the Libor Rate Period for such Libor Rate Portion.

                 f.       LATE CHARGE.  If any of the principal amount of any
Revolving Loan is not repaid, or any interest owing pursuant to this Agreement

date it becomes due, whether by acceleration or otherwise, the Borrower shall
pay to the Bank on demand made by the Bank a late charge of the greater of (i)

calendar quarter containing the date of this Agreement and ending before the
calendar quarter containing the day before the Revolving Loan Maturity Date or
(iii) beginning on the first day of the calendar quarter containing the day
before the Revolving Loan Maturity Date and ending on such day, the Borrower
shall pay to the Bank on demand made by the Bank a non-usage fee equal to the
product obtained by multiplying (A) the difference between $10,000,000 and the
daily average during such period of the aggregate outstanding principal amounts
of all Revolving Loans first by (B) 1/4% and then by (C) the fraction obtained
by dividing the number of days in such period by 360; provided, however, that
(I) in no event shall there be payable any such non-usage fee that would
result in interest being payable on the outstanding principal amount of any
<PAGE>   35
                                     - 26 -



Revolving Loan at a rate in excess of the maximum rate permitted by applicable
law and (II) solely to the extent necessary to result in such interest not
being payable at a rate in excess of such maximum rate, any amount that would
be treated as part of such interest under a final judicial interpretation of
applicable law shall be deemed to have been a mistake and automatically
canceled and, if received by the Bank, shall be refunded to the Borrower, it
being the intention of the Bank and the Borrower that such interest not be
payable at a rate in excess of such maximum rate.

calculated on the basis of a 360-day year for the actual number of days of each
year (365 or 366, as applicable), on such outstanding principal amount at a
rate per year that shall (i) on each day beginning before the maturity, whether
by acceleration or otherwise, of such outstanding principal amount be, as
selected by the Borrower before Term Loan II is made, (A) the total of (I) 1/2%
and (II) the rate in effect such day as the Bank's Prime Rate or (B) the total
of (I) 3% and (II) the most recent rate (as published by THE WALL STREET

                                     - 39 -



necessary to result in such interest not being payable at a rate in excess of
such maximum rate, any amount that would be treated as part of such interest
under a final judicial interpretation of applicable law shall be deemed to have
been a mistake and automatically canceled and, if received by the Bank, shall
be refunded to the Borrower, it being the intention of the Bank and the
Borrower that such interest not be payable at a rate in excess of such maximum
rate.  Except as otherwise provided in Section 4b or 4c of this Agreement,
