      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 27, 1996, are not necessarily indicative of the
   results to be expected for the full year.

2. During the first quarter of fiscal 1997, the Company adopted
   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".

   The Company's previous policy on impairment was not
   materially different than that prescribed by SFAS 121.  The
   adoption of SFAS 121 on April 1, 1996 did not require any
   impairment to be recognized during the twenty-six weeks ended
   September 27, 1996.

   As permitted by SFAS 123, the Company will continue to apply
   its current accounting policy under Accounting Principles
   Board Opinion No. 25, with respect to stock-based
   compensation.  The adoption of SFAS 123 on April 1, 1996,
   therefore, had no effect on the Company's consolidated
   financial position or results of operations for the twenty-
   six weeks ended September 27, 1996.

3. Receivables include costs and estimated earnings in excess of
   billings on uncompleted contracts which primarily represent
   revenues recognized on contracts, including retainage, for
   which billings could not be presented under the terms of the
   contracts at the balance sheet dates.

4. During the twenty-six weeks ended September 27, 1996, 65,771
   common shares were sold from the Company's Treasury and
   29,500 were purchased.  The total number of treasury shares
   as of September 27, 1996, was 77,193.

5. During the second quarter, the Company issued 202,814
   "repriced" options at the fair market value on the date of
   repricing, or $5.625.  These "repriced" options were given in
   exchange for the surrender of an equal number of previously
   issued options having exercise prices ranging from $13.125 to
   $17.75.  In addition, during the twenty-six weeks ended
   September 27, 1996, the Company issued 100,000 options under
   its Equity Incentive Plan and 15,000 options under its Stock
   Option Plan for Non-Employee Directors.  An aggregate of
   148,000 options expired during such period.  Accordingly,
   options for 374,659 shares were outstanding under the Equity
   Incentive Plan and 63,000 shares were outstanding under the
   Stock Option Plan for the Non-Employee Directors.  A total of
   119,845 shares were exercisable under both plans.

               INDEPENDENT AUDITORS' REVIEW REPORT



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 27, 1996,
and the related consolidated condensed statements of operations,
changes in shareholders' equity, and cash flows for the twenty-
six week periods ended September 27, 1996 and September 29, 1995.
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
obtaining an understanding of the system for the preparation of
interim financial information, applying analytical review
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, 1996, and the
related consolidated statements of operations, shareholders'
equity, and cash flows for each of the years in the three-year
period then ended (not presented herein); and in our report dated
May 14, 1996, we expressed an unqualified opinion on those
consolidated financial statements.  In our opinion, the
information set forth in the accompanying consolidated condensed
balance sheet as of March 31, 1996, is fairly presented, in all
material respects, in relation to the consolidated balance sheet
from which it has been derived.

              MANAGEMENT'S DISCUSSION AND ANALYSIS

FINANCIAL CONDITION

Operating activities were the primary sources of cash during the
six months ended September 27, 1996.   The Company's operations
provided positive cash flow of $1,893,000 for the first half of
fiscal 1997 compared with $340,000 for the first half of fiscal
1996.  Cash flow from operations for the second quarter was
essentially neutral due primarily to the receipt of approximately
$1,000,000 in expected collections after the close of the
quarter.  Receivables during the second quarter increased
$1,297,000 as a result of increased sales for the quarter of
approximately $900,000 and the timing of collections on those
sales.   Cash flow was used to acquire capital equipment, reduce
long term debt, and purchase shares for the treasury.   As of
September 27, 1996, the Company has purchased approximately
30,000 common shares for the treasury.

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

RESULTS OF OPERATIONS

Net sales for the second quarter increased 43% to $18,904,000 as
compared with the second quarter of fiscal 1996.  For the six
months ended September 27, 1996, net sales were $36,913,000, an
increase from fiscal 1996 of  46%.  The increase in net sales is,
in part, the result of activity on the Company's U.S. Navy
contract for Electronic Combat  Mission Support (ECMS).  In the
prior year, the Company experienced low subcontractor sales
volume on this contract.  Sales on the ECMS contract were $10.9
million for the first six months of fiscal 1997 compared with
$7.5 million for the first half of fiscal 1996.  In addition,
approximately half of the sales increase for both the second
quarter and the first six months is the result of the acquisition
of Advanced Systems Development, Inc. (ASDI) in March 1996.

The Company received additional funding on the ECMS contract
totaling $18.8 million during the second quarter.  This award,
along with several other smaller awards, has increased the
Company's backlog to over $116 million, a record high. Since,
March 31, 1996, backlog has increased 87%.

Gross margin percentage decreased for the second quarter to 16.2%
from 17.8% for the second quarter last year and 17.6% in the
first quarter of fiscal 1997.  For the first six months, gross
margin percentage decreased to 16.8% in fiscal 1997 from 17.1% in
fiscal 1996.  This decrease is primarily due to the effect of the
ECMS contract.  The margin on this cost-plus technical service
contract is typically lower than the Company's average gross
margin.

During the second quarter the Company continued to integrate the
acquired ASDI administration allowing for the Company to realize
overall cost reduction in Selling, General and Administrative
(SG&A) expenses.  Additionally, the Company experienced lower
than average marketing expenditures due to timing of trade shows
and proposal efforts.  SG&A for the first six months increased by
$433,000, when compared with fiscal 1996.  As a percentage of
sales, year to date SG&A decreased to 10.4% from 13.6% last year
due to the substantial increase in sales base. The current year
dollar increase is due to the acquired operations of ASDI in
March 1996. SG&A for the second quarter, as a percentage of
sales, was 9.9% compared with 12.9% last year and 11.1% for the
first quarter of fiscal 1997. The Company anticipates that SG&A
as a percentage of sales will increase slightly during the third
quarter.

Research and Development (R&D) expenditures for the second
quarter decreased by 32% when compared with the second quarter of
fiscal 1996 and 40% from the first quarter of fiscal 1997.  For
the first six months, R&D decreased by $241,000 when compared
with fiscal 1996.  In the prior year the Company had participated
in a cooperative research and development agreement (CRADA)
project with the U.S. Government which was completed last fiscal
year.  Additionally, in the prior year, the Company had incurred
R&D expenditures associated with the commercial operations prior
to its transfer to ARIA Wireless Systems, Inc. (ARIA).  Early in
the second quarter of fiscal 1997, the Company completed various
significant stages of development and enhancement of proprietary
military products, resulting in the second quarter reduction in
expenditures when compared with the first quarter of fiscal 1997.

Net interest expense increased by $72,000, for the second
quarter, and $214,000 for the first six months of operations, as
a result of long-term debt incurred as a part of the acquisition
of ASDI.  Net interest expense remained relatively constant for
the second quarter when compared with the first quarter of fiscal
1997.

The Company continues to record income taxes (Federal and state)
at the rate of 40%.  The Company's cash payments for taxes in
fiscal 1997 are being reduced due to its available net operating
loss (NOL) carryforward.  A statement of operations' benefit was
recorded by the Company in the periods when this NOL was
generated.

<PAGE 9>

During the second quarter of fiscal 1996, the Company recorded
income of $477,000 as a result of a settlement of litigation
between the Company and M-Wave, Inc. and its wholly-owned
subsidiary, Poly Circuits, Inc. This settlement included $300,000
in cash and 20,000 shares of M-Wave Stock.

In the second quarter of fiscal 1996, the Company recorded a loss
from its investment in ARIA of $1,035,000.  In the third quarter
of fiscal 1996, the value of this investment was written down to
zero.  As a result, this investment has, at this time, no further
negative financial impact on the Company's financial statements.
On April 30, 1996, ARIA filed a voluntary petition in the United
States Bankruptcy Court under Chapter 11 and subsequently has
secured approximately $1 million of debtor-in-possession
financing to facilitate a reorganization.  The Company continues
to closely monitor these proceedings in order to maximize the
Company's investment position.

RECENT ACCOUNTING PRONOUNCEMENTS

The Company adopted 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 Compensations on April 1, 1996.
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 annual financial statements.

   Re:  Purchase of 43,683 Treasury Shares

Dear Sirs:

This letter agreement (the "Agreement") sets forth the terms and
conditions of the purchase by the undersigned (the "Subscriber")
of 43,683 shares (the "Shares") of the Common Stock of Comptek
Research, Inc. (the "Corporation") from the Corporation's
treasury (the "Offering").  The parties hereto agree as follows:

   1. PURCHASE AND SALE.

   (a)  PURCHASE AND SALE OF SHARES.  Subject to the terms and
conditions of this Agreement, the Subscriber hereby subscribes to
purchase, and the Corporation hereby sells to the Subscriber,
43,683 Shares at a purchase price of $5.00 per Share.

   (b)  DELIVERY.  The Subscriber is delivering herewith a
personal check in the amount of $218,415, representing the
aggregate purchase price of the Subscriber's Shares as payment
therefor.  As soon as practicable, the Corporation shall deliver
to the Subscriber a certificate or certificates representing the
number of Shares the Subscriber is purchasing.

   2. REPRESENTATIONS AND WARRANTIES OF THE CORPORATION.  The
Corporation hereby represents and warrants to the Subscriber
that:

   (a)  INCORPORATION.  The Corporation is a corporation duly
organized and validly existing and in good standing under the
laws of New York and has all requisite corporate power and
authority to carry on its business.

   (b)  AUTHORIZATION.  All corporate action on the part of the
Corporation, its officers and directors necessary for the
authorization, execution, delivery and performance of all
obligations of the Corporation under this Agreement and for the
authorization, issuance and delivery of the Shares being sold
hereunder has been or shall be taken prior to the delivery of the
Shares, and this Agreement, when executed and delivered shall
constitute a binding and enforceable obligation of the
Corporation.

   (c)  VALIDITY OF SECURITIES.  The Shares to be purchased and
sold pursuant to this Agreement, when issued, sold and delivered
in accordance with its terms for the consideration expressed
herein, shall be duly and validly issued, fully paid and non-
assessable.

   3. REPRESENTATIONS BY SUBSCRIBER.  The Subscriber hereby
represents and warrants to the Corporation that:

   (a)  The Subscriber is acquiring the Shares for his own
account as principal, for investment and not with a view to
resale or distribution of all or any part of the Shares except in
accordance with and as provided for in this Agreement.

   (b)  Immediately prior to the purchase, the Subscriber has
such knowledge and experience in financial and business matters
that he is capable of evaluating the risks and merits of the
prospective investment.

   (c)  The Subscriber has been informed as to, and is familiar
with, the business activities of the Corporation.  The Subscriber
has been provided with copies of the Corporation's 1996 Annual
Report to Shareholders, the Corporation's proxy statement used in
connection with the solicitation of proxies for its 1996 Annual
Meeting of Shareholders and the Corporation's Form 10-K Report
for fiscal year 1996.

   (d)  The Subscriber has had an opportunity to ask questions
of, and receive answers from, appropriate representatives of the
Corporation concerning the Corporation, its business, and the
terms and conditions of the Offering, and to obtain such
additional information as the Subscriber deems necessary to
verify the accuracy and adequacy of the information it has
obtained.  The Subscriber fully understands that this Offering
has not been registered under the Securities Act of 1933 (the
"Securities Act") in reliance upon exemptions therefrom, and,
accordingly, to the

<PAGE 15>

extent that he is not supplied with information which would have
been contained in a registration statement filed under the
Securities Act, he it must rely on his own access to such
information.

   (e)  The Subscriber affirms that he is an "accredited
investor" as that term is defined and construed pursuant to Rule
501 under the Securities Act because the Subscriber is an
executive officer of the Corporation.

   (f)  The Subscriber fully understands and agrees that the
Subscriber must bear the economic risk of his investment in the
Shares for an indefinite period of time because, among other
reasons, the Shares have not been registered under the Securities
Act, and, therefore, cannot be sold, pledged, assigned or
otherwise disposed of unless they are subsequently registered
under the Securities Act or, in the opinion of counsel acceptable
to the Corporation, an exemption from such registration is
available.

   (g)  The Subscriber understands that no federal or state
agency has passed upon the offering of the Shares or made any
finding or determination as to the fairness of the offering the
Shares.


   4. BROKERS' FEES.  The Corporation and the Subscriber
represent and agree that the transactions contemplated by this
Agreement have been carried on by the parties directly and
without the intervention of any other person in such manner as to
give rise to any valid claim against either party for a finder's
fee, brokerage commission or other similar payment.

      5.    RESTRICTION ON TRANSFERABILITY OF SHARES, COMPLIANCE
      WITH SECURITIES ACT OF 1933.

   (a)  RESTRICTIONS ON TRANSFERABILITY.  The Shares shall not be
transferable except upon the conditions specified in this Section
5, which conditions are intended to ensure compliance with the
provisions of the Securities Act in respect of the transfer of
the Shares.

   (b)  CERTAIN DEFINITIONS.  As used in this Section 5, the
following terms shall have the following respective meanings:

      "COMMISSION" shall mean the Securities and Exchange
Commission or any other federal agency at the time administering
the Securities Act and the Exchange Act.

      "EXCHANGE ACT" shall mean the Securities Exchange Act of
1934, as amended, or any successor federal statute, and the rules
and regulations of the Commission thereunder, all as the same
shall be in effect at the time.

      "SECURITIES ACT" shall mean the Securities Act of 1933, as
amended, or any successor federal statute, and the rules and
regulations of the Commission thereunder, all as the same shall
be in effect at the time.

      "REGISTRATION STOCK" shall mean those Shares designated by
the Subscriber pursuant to Section 5(d) as includable in the
registration to be made by the Corporation hereunder.

      "REGISTRATION EXPENSES" shall mean all expenses incurred by
the Corporation in complying with Subsection 6(d), including,
without limitation, printing expenses, fees and disbursements of
counsel to the Corporation, the fees and expenses in connection
with all registrations or exemption from registration under
federal securities law and state securities law affecting the
transfer of the Registration Stock ("Blue Sky Expenses") in New
York, and the expenses of any regular or special audits incident
to or required by any such registration (and including the
compensation of regular employees of the Corporation involved in
such registration).

      "SELLING EXPENSES" shall mean all underwriting discounts
and selling commissions applicable to the sales, and any state or
federal transfer taxes payable with respect to the sales, of the
Registration Stock, all Blue Sky Expenses for any state other
than New York, any state or federal transfer taxes payable with
respect to the sales of Registration Stock, and all fees and

   (c)  SHARES TO BE LEGENDED.  A restrictive legend in
substantially the following form will be imprinted on the
certificates evidencing the Shares and stop transfer orders or
other appropriate instructions to such effect will be maintained

Corporation or its transfer agent:

               "The Shares represented by this Certificate have not been
               registered under the Securities Act of 1933 (the "Act").  The
               Shares have been acquired for
<PAGE 16>

               investment and may not be sold, transferred, pledged or
               otherwise disposed of in the absence of an effective
               Registration Statement for the Shares under the Act or an
               opinion of counsel satisfactory to the issuer that the proposed
               disposition of the Shares will not violate Section 5 of the
               Act."

     The transfer of the Shares on the books and records of the
Corporation will only be effected in accordance with such legend.

     (d)  REQUIRED REGISTRATION. Upon notice by the Subscriber to
the Corporation, given not less than four months after the date
of this Agreement and at such time as the Subscriber is not
entitled to sell the Shares publicly without registration under
Rule 144 or another available exemption to the registration
requirements of the Securities Act, of the Subscriber's desire to
sell all or some of the Shares pursuant to an effective
registration statement under the Securities Act, the Corporation
shall forthwith proceed to:

          (i)  prepare and file with the Commission a
registration statement on Form S-3 (a successor form) with
respect to the Registration Stock, use its best efforts to cause
it to become and remain effective until the earlier of such time
as Subscriber is entitled to sell the Shares under Rule 144, or
other available exemption;

          (ii) prepare and file with the Commission such
amendments and supplements to such registration statement and
prospectus used in connection therewith as may be necessary to
keep such registration statement effective, and to comply with
the provisions of the Securities Act with respect to delivery of
prospectuses for the period during which the information
contained in the prospectus would not have to be updated pursuant
to Section 10(a)(3) of the Securities Act; provided, however,
that if at any time during such period of effectiveness the
Corporation shall request that the Subscriber withhold its Shares
of Registration Stock from sale because of the Corporation's
temporary inability to furnish the Subscriber with a prospectus
meeting the requirements of the Securities Act (other than as a
result of the application of Section 10(a)(3) of the Securities
Act), the Subscriber shall refrain from selling such Registration
Stock on the condition that the Corporation shall file such
amendments and supplements to such registration statement and
prospectus issued in connection therewith as may be necessary in
order to permit the sale of the Registration Stock to the public
in compliance with the Securities Act for an additional amount of
time equal to the period of time that the Subscriber was required
to refrain from selling such Registration Stock;

          (iii)     furnish to the Subscriber such number of
copies of a prospectus in conformity with the requirements of the
Securities Act, and such other documents, as the Subscriber may
reasonably request in order to facilitate the public sale or
other disposition of the Registration Stock owned by the
Subscriber; and

          (iv) use its best efforts to register or qualify the
Registration Stock covered by such registration statement under
such other securities or blue sky laws of such jurisdictions as
the Subscriber shall reasonably request (not exceeding five in
number unless otherwise agreed by the Corporation) as shall be
reasonably appropriate for the distribution of the Registration
Stock covered by such registration statement, provided that the
Corporation shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general
consent to service of process in any such states or jurisdiction,
and do any and all other acts and things which may be necessary
or desirable to enable the Subscriber to consummate the public
sale or other disposition of the Registration Stock in such
jurisdictions;

     (e)  INDEMNIFICATION BY THE CORPORATION.  In the event of
any registration of any Registration Stock under the Securities
Act, the Corporation shall, and hereby does, indemnify and hold
harmless in the case of any registration statement filed pursuant
to Section 5, the Subscriber, each other person who participates
as an underwriter in the offering or sale of Registration Shares
and each other person, if any, who controls such seller or any
such underwriter within the meaning of Section 15 of the
Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which the Subscriber or any
such director or officer or underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any
registration statement under which the Registration Shares were
registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated
therein or necessary to make the statements therein in light of
the circumstances in which they were made not misleading, and the
Corporation shall reimburse the Subscriber, and each such
underwriter and controlling person for any legal or any other
expenses reasonably incurred by them in connection with
investigating or

<PAGE 17>

defending any such loss, claim, liability, action or proceeding;
provided that the Corporation shall not be liable in any such
case to the extent that any such loss, claim, damage, liability
(or action or proceeding in respect thereof) or expense arises
out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such
registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information
furnished to the Corporation by or on behalf of the Subscriber or
such underwriter, as the case may be, specifically stating that
it is for use in the preparation thereof; and provided further
that the Corporation shall not be liable to any person who
participates as an underwriter in the offering or sale of
Registration Stock or any other person, if any, who controls such
underwriter within the meaning of the Securities Act, in any such
case to the extent that any such loss, claim, damage, liability
(or action or proceeding in respect thereof) or expense arises
out of such person's failure to send or give a copy of the final
prospectus, as the same may be then supplemented or amended, to
the person asserting an untrue statement or alleged untrue
statement or omission or alleged omission at or prior to the
written confirmation of the sale of Registration Stock to such
person if such statement or omission was corrected in such final
prospectus.

     (f)  INDEMNIFICATION BY THE SUBSCRIBER.  In the event of any
registration of Registration Stock under Section 5(d), the
Subscriber shall, and hereby does indemnify and hold harmless (in
the same manner and to the same extent as set forth in Section
5(e)) the Corporation, each director of the Corporation, each
officer of the Corporation and each other person, if any, who
controls the Corporation within the meaning of Section 15 of the
Securities Act, with respect to any statement or alleged
statement in or omission or alleged omission from such
registration statement, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, if such statement or alleged
statement or omission or alleged omission was made in reliance
upon and in conformity with information about the Subscriber
furnished to the Corporation by the Subscriber for use in the
preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or
supplement.

     (g)  COOPERATION, FURNISHING OF INFORMATION.  It shall be a
condition precedent to the obligation of the Corporation to take
any action pursuant to Section 5(d) that the Subscriber shall
furnish to the Corporation promptly such information regarding
the Subscriber, the Shares held by the Subscriber, and the
intended method of disposition of the Registration Stock as the
Corporation shall reasonably request and as shall be required in
connection with the registrations to be undertaken by the
Corporation.

     (h)  EXPENSE.  The Corporation shall pay all Registration
Expenses, as defined herein, and the Subscriber shall pay all
Selling Expenses, as defined herein, required in connection with
a registration of the Registration Stock.

     6.   MISCELLANEOUS.

     (a)  APPLICABLE LAW.  This Agreement shall be construed in
accordance with and governed by the laws of the State of New
York.

     (b)  STATE IN WHICH OFFERED.  The Shares are offered to and
will be purchased by the Subscriber in the State of New York.

     (c)  BINDING EFFECT.  Except as otherwise provided herein,
this Agreement shall be binding upon and inure to the benefit of
the parties and their successors, legal representatives and
assigns.

     (d)  NO ASSIGNMENTS.  The Subscriber agrees that except as
provided herein neither it nor its legal representatives will
sell, assign, encumber or transfer, in any manner whatsoever,
this Agreement or its rights under this Agreement.

entire agreement between the parties pertaining to the subject
matter hereof and supersedes any prior understandings, oral or
written.

      Loan Agreement between Comptek Federal Systems, Inc.
          (subsidiary of Registrant) and John J. Sciuto

<PAGE 20>
                         LOAN AGREEMENT

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


     AGREEMENT dated as of July 9, 1996, by and between Comptek
Federal Systems, Inc., a New York Corporation, having its
principal office at 2732 Transit Road, Buffalo, New York 14224
("Comptek"), and John J. Sciuto, residing at 6392 Black Walnut
Court, East Amherst, New York 14051 (the "Borrower").

                           WITNESSETH:

     In consideration of the mutual covenants contained herein
and for other good and valuable consideration, the parties hereto
agree as follows:

     1.   Loan.

     Comptek hereby agrees, on the terms and conditions set forth
herein, to loan to Borrower the principal amount of two hundred
eighteen thousand four hundred fifteen dollars ($218,415).  Such
loan shall be evidenced by and repayable with interest in
accordance with a Promissory Note of the Borrower payable to the
order of Comptek in the form of Exhibit A attached hereto (the
"Promissory Note").

     2.   Security Interest.

     The Borrower hereby agrees concurrently with the execution
and delivery of the Promissory Note to grant a security interest
to Comptek in 43,683 shares of Common Stock of Comptek Research,
Inc. and to deliver to Comptek the stock certificate or
certificates representing such shares together with a stock
transfer power signed in blank to be held by Comptek as security
for the payment of all indebtedness and other obligations of
Borrower under the Promissory Note until the loan provided for in
this Agreement is repaid in full.

     3.   Application of Incentive Compensation.

     The Borrower hereby agrees to pay over to Comptek to be
applied against the outstanding balance of principal and interest
on the Promissory Note a minimum of twenty-five percent (25%) of
the gross amount of any incentive compensation paid to the
Borrower by Comptek or any of its affiliates, such payment by the
Borrower to be made within ten (10) days of the Borrower's
receipt of such incentive compensation.

          4.   Election to Apply Additional Incentive Compensation
     Amounts.

     In addition to the amount specified in paragraph 3, the
Borrower may, at his sole election, direct that a greater
percentage of any incentive compensation payable to him be
applied to the Promissory Note.  In the event that the Borrower
elects with respect to any fiscal year to have an amount of
incentive compensation equal to at least fifty percent (50%) of
the gross amount applied to the Promissory Note, Comptek agrees
to (i) gross-up the amount of the incentive compensation payment
applied to the Promissory Note by fifty percent (50%) to
accommodate any tax liability imposed upon Borrower in connection
with such incentive compensation payment and (ii) pay a tax bonus
in the amount of fifty percent (50%) of any imputed interest upon
the Promissory Note for such fiscal year to accommodate any tax
liabilities imposed upon the Borrower based upon the rate of
interest being charged on the loan.  Such election by the
Borrower, to be effective must be irrevocable and made at least
six (6) months prior to the end of the fiscal year for which such
incentive compensation is payable.

     5.   Use of Proceeds.

     The Borrower agrees that the principal amount of the loan
will be used solely to purchase shares of Comptek Research, Inc.

<PAGE 21>

     6.   Further Actions.

     Promptly upon the request of Comptek, the Borrower shall
execute and deliver, or cause to be executed and delivered, each
writing, and take or cause to be taken each other action, that
Comptek shall deem necessary or desirable in connection with the
transaction and security interest contemplated by this Agreement

     7.   Governing Law.

     This Agreement shall be governed by the laws of the State of
New York, without giving effect to the principles of conflicts of
law.

     IN WITNESS WHEREOF, the parties have caused this Agreement
to be duly executed as of the day and year first above written.

$218,415  Buffalo, New York
                                                     July 9, 1996


     FOR VALUE RECEIVED, the undersigned, John J. Sciuto,
residing at 6392 Black Walnut Court, East Amherst, New York 14051
(the "Borrower"), HEREBY PROMISES TO PAY to the order of COMPTEK
FEDERAL SYSTEMS, INC.,  a New York, corporation ("Comptek"), at
the offices of Comptek, 2732 Transit Road, Buffalo, New York
14224, the principal amount of TWO HUNDRED EIGHTEEN THOUSAND,
FOUR HUNDRED FIFTEEN DOLLARS ($218,415) in lawful money of the
United States on or before the Final Payment Date as specified
herein.  The "Final Payment Date" shall be deemed to be the
earliest to occur of the following dates: (i) July 8, 2001; (ii)
the ninetieth (90th) day after the day on which Borrower ceases
to be employed by either Comptek  or one of its affiliates; (iii)
the tenth (10th) day after the date of an Event of Default (as
defined herein).

     The Borrower further agrees to pay interest, as hereinafter
provided, in like money at such office on the unpaid principal
amount hereof from time to time outstanding, and on any other
amount payable by the Borrower hereunder to the extent permitted
by applicable law, from the date hereof through and including the
Payment Date, at the rate of three and seven-tenths percent
(3.7%) per annum, based on actual days outstanding and a 360-day
year.

     The Borrower hereby agrees to pay principal and interest due
hereunder no later than the Final Payment Date.  If any principal
or accrued interest remain unpaid after the Payment Date (the
"Aggregate Past Due Balance"), the Borrower agrees to pay
interest on the Aggregate Past Due Balance at the rate of twelve
percent (12%) per annum based on the actual days outstanding
between the Payment Date and the date of repayment of the entire
Aggregate Past Due Balance and a 360-day year.

     This Promissory Note is secured by shares of Common Stock of
Comptek Research, Inc. owned by or hereinafter acquired by
Borrower.

     The Borrower may prepay at any time, without penalty, any
amounts due hereunder.

     Each of the following occurrences shall constitute an event
of default ("Event of Default"): (a) failure of Borrower to apply
at least twenty-five percent (25%) of the gross amount of any
incentive compensation payment received by Borrower from Comptek
or its affiliates, while this Promissory Note is outstanding, to
the

<PAGE 23>

payment of principal outstanding on this Promissory Note as
provided for in Loan Agreement, dated as of the date hereof by
and between Comptek and the Borrower; (b) the sale or other
transfer by Borrower of any shares of Common Stock of Comptek
Research, Inc., pledged as security on this Promissory Note.

     This Promissory Note shall be governed by, and construed and
interpreted in accordance with, the laws of the State of New
York, without regards to conflicts of law principles, except as
preempted by Federal law.

     The failure to assert any right hereunder shall not be
deemed a waiver of such right.
