                  LETTER FOR COMMISSION ONLY -
         NOT TO BE INCLUDED AS PART OF THE EDGAR FILING



June 25, 1999

James M. Daly, Esq.
Assistant Director
United States Securities and Exchange Commission
Division of Corporation Finance
450 Fifth Street, N.W., Mail Stop 4-6
Washington, D.C.  20549

     Re:  Comptek Research, Inc.
          Registration Statement on Form S-2
          File Number 333-77045

Dear Mr. Daly:

This letter is submitted on behalf of Comptek Research, Inc.
("Company") and sets forth the responses of the Company to the
comments of the staff of the Securities and Exchange Commission
("Commission") concerning the Registration Statement on Form S-3,
filed on April 26, 1999 (File No. 333-77045) (the "Registration
Statement"), which were sent by the Commission to the Company by
letter dated May 25, 1999.  The comments of the staff are
reproduced below.

With this response letter, the Company is filing Amendment No. 1
to the Registration Statement ("Amendment No. 1"), which converts
the Registration Statement to Form S-2.  Amendment No. 1 has been
marked to show changes from the initial filing.  Capitalized
terms not defined herein have the same meaning as in Amendment
No. 1.

In addition to addressing the specific comments of the staff, we
have updated all financial information based on the Company's
audited results for the fiscal year ended March 31, 1999, which
were not available at the time of our initial filing.  For
example, the ratio of earnings to fixed charges now includes the
full year for fiscal 1999, rather than the nine month period.
Incorporated by reference is the Company's Form 10-K Report for
the year ended March 31, 1999, in place of the prior year's 10-K
and interim 10-Q Reports.  The Company expects to file the
current 10-K Report on or before June 29, 1999, and, in any
event, will have it filed prior to requesting acceleration of the
effectiveness of the Registration Statement.

Form S-3 Eligibility

Convertible Subordinated Debentures

1.   We note that you seek to register a secondary offering
     consisting of convertible debentures and the related common
     shares issuable upon conversion of the debentures held by
     the selling security holders listed at page 27 of the
     prospectus.  Please note that you can only register a
     secondary offering of outstanding securities, "if securities
     of the same class are listed and registered on a national
     securities exchange or are quoted on the automated quotation
     system of a national securities association."  See
     Instruction I.B.3 of Form S-3.  Accordingly, it appears that
     you can not conduct a secondary offering of the convertible
     debentures covered by this registration statement because
     the offering does not meet the applicable transaction
     requirements of Form S-3.  Revise the registration statement
     accordingly.

     We have amended the Registration Statement to Form S-2.

Common Shares to be Issued Upon Conversion of the Debentures

2.   According to the selling security holder table at page 27,
     CIBC Oppenheimer Corp. and Warburg Pincus Emerging Growth
     Fund propose to sell securities, including the common shares
     to be issued upon conversion of the debentures, in a
     secondary offering covered by this registration statement.
     Please note that any selling security holder that is either
     a registered broker/dealer, or engaged in the activities of
     a broker/dealer, or affiliated in any manner with a
     registered broker/dealer, will be considered a statutory
     "underwriter" in the offering, and the offering will
     constitute a primary offering of securities by the company.
     Revise the prospectus so that each applicable selling
     security holder is identified as an underwriter in the
     offering and register the offering as a primary offering by
     the company.

     CIBC Oppenheimer Corp. does not hold any securities.  We
     have revised the "Plan of Distribution" wherein the
     affiliations of Warburg Pincus Emerging Growth Fund and
     Joseph Stechler & Company Incorporated have been disclosed
     and each of those entities has been identified as an
     underwriter.

Primary Offering by Comptek

3.   As indicated in the comments above, you can not register
     either the debentures or the common shares to be issued upon
     conversion of the debentures as a secondary offering by the
     selling security holders on Form S-3.  In addition, we also
     note that in order to conduct a primary offering of these
     securities on Form S-3, you must satisfy the eligibility
     requirements for a primary offering as described in
     Instruction I.B.1 of the form.  According to this
     instruction, in order to use Form S-3 for a primary
     offering, the aggregate market value of your voting and non-
     voting common equity held by non-affiliates must be $75
     million dollars or more.  Based on this criteria, it appears
     that you do not qualify to use Form S-3 for a primary
     offering.  Please re-file the registration  statement on the
     appropriate form, as Form S-3 is not available for either a
     secondary or primary offering by the company or the selling
     security holders.

     We have amended the Registration Statement to Form S-2.

Plain English Disclosure Compliance

4.   Notwithstanding the unavailability of Form S-3 for this
     offering, we have the following comments on the disclosure
     provided.  Please note that the following comments would
     only apply to a valid secondary offering by selling security
     holders registered on Form S-3.  When you re-file the
     registration statement on the appropriate form, please
     ensure that all portions of the revised registration
     statement are consistent with the plain English rules.

General

5.   Do not use the generic term "Company" in your document.
     This term is not descriptive and may be confusing to the
     reader.  Either use the proper name of the company or use
     pronouns such as "us" or "we" when the company's identity is
     clear from context.  Also, revise the related reference
     under, "About This Prospectus."

     All references to the "Company" have been removed.

6.   Throughout the document, we note you define terms in
     quotation marks and parenthetical phrases. For example, you
     define "DOD," "EW," "Repurchase Price," "Repurchase Date"
     and "Code."  Defined terms should not appear in the forepart
     of the prospectus. These sections include cover page,
     summary or risk factors.  They should also be used
     sparingly, if at all, in the remainder of the document.  In
     most cases, defined terms will not be necessary because they
     are already clear from context or easily explained by a
     brief description in the prospectus.  Revise accordingly.

     We have removed all unnecessary definitions.

7.   We also note that some of the sections in your document
     contain parenthetical phrases that disrupt the flow of
     information and make these sentences very long.  As a
     result, investors will have to read them several times to
     figure out what you are disclosing.  You should attempt to
     eliminate parenthetical phrases throughout your document.
     If the information in the parenthetical phrases is important
     enough to be included in the disclosure, include it in its
     own sentence.

     We have complied with this comment.

8.   As a related matter, we note that some of the sentences in
     your document are too long to understand on the first
     reading because you have embedded lists of information in
     paragraph form.  See, for example, the footnotes to the
     tables in the "Recent Developments" section and page 28
     under "Plan of Distribution."  Rather than include these
     lists in the paragraph, break them out into bullet points,
     with one bullet point for each list item.  Also, avoid using
     small roman numerals throughout your document, as they are
     more difficult to follow than letters or Arabic numbers.

     We have complied with this comment.

9.   Whenever possible, you should minimize the use of footnotes
     in your document.  If the footnotes apply to the entire
     table or chart or to an entire column of information, then
     include it in the narrative discussion.  In most cases, the
     information in the footnotes could be presented in the
     textual disclosure preceding or following the table without
     causing confusion.  Please revise where appropriate. See
     "Recent Developments," and the selling security holder table
     at page 27.

     We have complied with this comment.

Cover Page

10.  Using all capital letters in legends and headings of the
     document makes the information difficult to read.  Except
     for the first word in each sentence, use lower case letters.
     If you want to emphasize information, use methods like
     bolded letters or italics.  Revise the legends and section
     headings throughout the document.

     We have complied with this comment.

11.  Your cover page includes more information than is required
     by Item 501 of Regulation S-K.  For example, you disclose
     information regarding the private placement of the
     debentures, the terms of the debentures, the use of proceeds
     and the plan of distribution.  Only the information required
     by Item 501 and information essential to an investment
     decision should be disclosed on the cover page.  Remove all
     other information from the cover page.  If you believe this
     information is material to the offering, disclose this
     information elsewhere in the prospectus.

     We have complied with this comment.

12.  Please identify the selling security holders on the cover
     page by providing a page reference to the table in the
     prospectus.  Our suggested disclosure for the first sentence
     of this page is, "The selling security holders, as listed on
     page 27, offer for sale."  Any additional information
     regarding the selling security holders should appear under
     the appropriate section of the prospectus.

     We have complied with this comment.

Forward Looking Information

13.  To present the information in the prospectus from an
     investor's perspective, we suggest that you move this
     information so that it appears after the risk factors.

     We have complied with this comment.

14. We also note that the prospectus states that it includes
    forward-looking statements within the meaning of the
    Litigation Reform Act.  Please be advised that we are not
    making any determination as to whether the disclosures,
    including the cautionary language or the placement of
    disclosures, satisfy the requirements of the Litigation
    Reform Act and the applicable sections of the Securities Act
    and the Exchange Act.

    We have complied with this comment.

How to Obtain More Information, pages 2-3

15. We suggest that you move this section to the back of the
document.

    We have complied with this comment.

Summary, Pages 9-11

16. Although the summary is not required to contain all of the
    material information regarding the offering, it can not be
    qualified by a statement such as, "this summary is not
    complete."  Please revise.

    We have complied with this comment.

17. We note the table summarizing the terms of the debentures.
    Please ensure that you use a font size and layout that are
    easy to read.

    We have complied with this comment.

Risk Factors, page 12-15

18. Revise your risk factor subheadings so that you are stating
    a fact or uncertainty about your business and then
    summarizing the risks that may result from these facts and
    events.  For example, the subheading "Fixed-Price Contracts
    - Our Percentage of Fixed-Priced Contracts, Which Are A
    Higher Risk, Is Increasing," does not convey the risk
    associated with fixed-price contracts, as they relate to
    your business.  Review and revise each subheading to ensure
    that it discloses the specific risk that you are discussing
    in the text of the risk factor.  See Item 503(c) of
    Regulation S-K.

    We have complied with this comment.

19. Item 503(c) of Regulation S-K states that registrants should
    not "present risk factors that could apply to any issuer or
    to any offering,"  For example, see "International Sales -
    ." The listed risk factors could apply to nearly any issuer
    in your industry and even other industries.  If you elect to
    retain these risk factors, you must clearly explain how they
    apply to your industry, company, or offering.

    We have complied with this comment.

20. As a related matter, avoid the generic conclusions you make
    in most of your risk factors that the risk discussed would
    have a material adverse effect on your operations or
    financial condition.  Instead, replace the language with
    specific disclosure of how your operations or financial
    results would be affected.

    We have complied with this comment.

Description of Debentures, pages 19-26


21. We note that you seek to qualify the completeness of the
    disclosure in this section "in its entirety" by reference to
    the related documents found outside the prospectus.  Please
    note that the text of the prospectus must be materially
    complete, and all text suggesting that it is not materially
    complete should be modified.

    We have complied with this comment.

22. We note the extensive use of legalese in this section and
    the following sections of the prospectus.  Whenever
    possible, you should avoid the use of legalistic words and
    phrases.  For example, you use the term "such".  "Such" is
    legalese for "this", "these", or "the".  Some other examples
    include legalistic words like "herein," "thereof," "hereby,"
    "therewith," "certain" "hereafter", "thereby" and
    "pursuant."  Please replace all legalistic terms throughout
    your prospectus with concrete, everyday words that mean the
    same thing.

    We have complied with this comment.

23. We also suggest that you rewrite these sections to eliminate
    the unnecessarily long sentences which make the disclosure
    difficult to read and follow.  For example, see the
    discussion of Rule 144 on page 27.  Instead of using long,
    verbose sentences that contain legalese, shorten the
    sentences and use everyday, concrete language.

    We have complied with this comment.

Part II of the Registration Statement, Signatures

24. Please note that the principal executive officer and the
    principal financial or accounting officer must sign the
    registration statement in this capacity.   See Instruction 1
    to Part II, Signatures of Form S-3.

    We have complied with this comment.

Should the staff of the Commission have any comments or questions
regarding Amendment No. 1 or this response letter, please call
the undersigned at (716) 677-4070.

Sincerely,

                    <BOLD><ITALIC>Prospectus

The information in this prospectus is not complete and may be
changed.  The selling security holders may not sell these
securities until the registration statement, filed with the
Securities and Exchange Commission, is effective.  This
prospectus is not an offer to sell these securities and is not
soliciting an offer to buy these securities in any state where
the offer of sale is not permitted.

          Subject To Completion, Dated June ___, 1999

                    Comptek Research, Inc.

1,578,947 Shares Of Common Stock Issuable Upon Conversion Of The
                   Debentures</ITALIC></BOLD>

The selling security holders, as listed on page 20, are offering
for sale our 8 1/2% convertible subordinated debentures and shares
of our common stock into which the debentures are convertible.
The debentures and the shares are being offered on a continuous
basis until at least June __, 2001 or the earlier sale of all the
debentures and shares of common stock.

The debentures and shares of common stock may be sold at market
prices prevailing at the time of sale or at privately negotiated
prices.

On June 14, 1999, the closing price of our common stock on the
American Stock Exchange symbol "CTK" was $8.4375 per share.  We
do not intend to apply for listing of the debentures on any
securities exchange or for quotation through any automated
quotation system.

Eight and one-half percent (8 1/2%) annual interest is payable on
the debentures on October 1 and April 1 each year, beginning
October 1, 1999 until converted to common stock or maturity at
April 1, 2004.  The debentures are convertible into shares of
common stock at the rate of $9.50 per share, subject to
adjustments in certain events.

   <BOLD><ITALIC>Investing in the debentures or the common stock
into which the debentures are convertible involves a high degree
of risk.  See "Risk Factors" commencing on page 7  for a
discussion of some important risks you should consider before
buying any debentures or any shares of common stock.

Neither the Securities and Exchange Commission nor any state
securities commission has approved or disapproved of these
securities or passed upon the accuracy or adequacy of this
prospectus.  Any representation to the contrary is a criminal
offense. </BOLD>

This summary highlights information contained in this prospectus
or incorporated by reference into this prospectus from our
current filings with the SEC. </ITALICS>

<BOLD>Overview</BOLD>

Comptek develops and integrates surveillance and communications
systems used primarily for military applications.  We provide
engineering and project management services for electronic
warfare systems. Our products and services enhance the
operational performance and readiness of existing weapons
systems, as well as extend their useful lives and survivability.
We have been involved in either the development, lifecycle
support or testing of nearly all of the major electronic warfare
systems that have been fielded by either the United States Air
Force or United States Navy since 1974, including systems for B-
1B Lancer and B-2A Spirit bombers; EF-111 Raven, EA-6B Prowler
and F/A-18 Hornet aircraft; and navy surface combatants including
AEGIS class destroyers and cruisers.

Our primary activities are:

*  Tactical Systems.  Comptek is a leading supplier of
  electronic warfare systems used for the processing of intercepted
  radar signals, threat analysis and counter measures.  We also
  provides command and control, mission planning and air combat
  measurement instrumentation systems.

* Electronic Warfare Simulation/Stimulation and Training.  We
  specialize in the design, development and manufacture of
  electronic environment simulators.  We supply stimulators used to
  test military electronics surveillance, equipment including
  electronic warfare systems, radar warning receivers and
  electronic counter-measures equipment.

* Engineering and Technical Services.  We provide a wide range
  of technical and engineering services, including systems design
  and integration, software development and test, project
  management and support for the design, operation, maintenance and
  upgrade of weapon and information systems.

   Our customers include the U.S. Department of Defense, all of
the branches of the United States Armed Forces, and certain
foreign governments.  Our present prime contractor relationships
include the Boeing Company, GEC-Marconi Hazeltine Corporation,
Lockheed Martin Corporation, Northrop Grumman Corporation and the
Raytheon Company.  International customers include the foreign
governments of Australia, Canada, France, Germany, Israel, Italy,
Japan, Sweden, Switzerland and the United Kingdom.

Expansion through acquisitions and increased international
activities have both been, and continue to be, important elements
of our business strategy.  Over the last three years, we have
acquired three private companies.  In March 1996, we acquired
Advanced Systems Development, Inc., a highly-specialized
developer of electronic warfare simulation/stimulation, training
and software validation systems related to electronic
surveillance.  Largely as a result of the acquisition of Advanced
Systems Development, Inc., we substantially increased our
presence in international markets.  Effective May 1, 1998, we
completed our acquisition of PRB Associates, Inc., a leader in
the development of military mission-planning and precision-
targeting systems.  On March 26, 1999, we completed the purchase
of the business operations and substantially all of the related
assets and liabilities of Amherst Systems, Inc., a firm
specializing in simulation/stimulation and evaluation systems for
electronic defense applications.  We paid a purchase price of $30
million and assumed Amherst Systems's long-term debt of $5.1
million.  We paid the purchase price by delivering to Amherst
Systems $20 million in cash and $10 million in subordinated
promissory notes of Comptek.

<PAGE 5>
                  <BOLD><ITALICS>Risk Factors

You should carefully consider the risks and uncertainties
described below and the other information in this prospectus and
in any documents incorporated in the prospectus, before making an
investment decision.<ITALICS>

   We are dependent on future military spending  because
substantially all of our sales are derived from military
requirements.</BOLD>

We are subject to changes in national defense policies and
priorities and changes in government appropriations.  In recent
years, a reduction in the defense budgets of many countries has
caused many defense-related government contractors to experience
declining revenues.  There can be no assurance that a continued
decline in worldwide military spending will not affect our
ability to increase revenues and may result in declines in future
revenues and may have a material adverse impact on our business,
financial condition or results of operations.

<BOLD>We are heavily dependent on U.S. Government contracts  and
as a U.S. Government contractor we are subject to specialized
rules and regulations.</BOLD>

Historically in excess of 85.0% of our revenues have been
attributable to contracts with departments and agencies of the
U.S. Government, specifically the Department of Defense.  As a
contractor and subcontractor to the U.S. Government, we are
subject to various laws and regulations that are more restrictive
than those applicable to non-government contractors.  U.S.
Government contracts are subject to special risks, such as:

  *    delay in funding;

  *    early termination;

  *    reduction or modification due to changes in policies or as
     the result of budgetary constraints, political changes or other
     factors that do not depend on Comptek;

  *    the U.S. Government's rights to technical data and to audit
     financial data; and

  *    the ability of U.S. Government and its agencies unilaterally
     to suspend contractors from receiving new contracts pending
     resolution of alleged violations of procurement laws or
     regulations.

   Government agencies often have complex and time-consuming
procurement procedures.  We generally obtain military contracts
through a competitive bidding process in which, in many
instances, numerous bidders participate.  There can be no
assurance that we will continue to be successful in having our
bids accepted which would affect our ability to increase revenues
and may result in declines in future revenues.

<BOLD>Our risk of sustaining a loss is greater with a fixed-price
contract as opposed to a cost-plus contract. Our percentage of
fixed-price contracts is increasing.</BOLD>

For the fiscal year ended March 31, 1999, approximately 29.0% of
our sales were recorded on fixed-price contracts, as opposed to
cost-plus or cost-sharing contracts.  Under fixed-price
contracts, we assume the risk that increased or unexpected costs
may reduce profits or cause a loss.  To the extent that actual
costs exceed the projected costs on which bids or contract prices
are based, Comptek could  sustain a loss under the contract.
Since a majority of the contracts we acquired from Amherst
Systems, Inc. are fixed-price, we expect the percentage of fixed-
price work to increase and therefore increase our exposure to
potential

<PAGE 6>



losses on individual contracts.  For the fiscal year ended March
31, 1999, as adjusted to give effect to the business operations
acquired from Amherst Systems,  40.2% of the our sales would have
been fixed-price.

<BOLD>The integration of our recent acquisitions and the making
of future acquisitions could adversely impact our current
operations.</BOLD>

Our acquisitions of Advanced Systems Development in March 1996,
of PRB Associates in May 1998, and of the business operations of
Amherst Systems in March 1999 are part of a business development
strategy which seeks internally- and externally-generated sales
growth in niche markets.  While there are currently no
commitments with respect to any future acquisitions, we
frequently evaluate the strategic opportunities available to us
and expect to pursue acquisitions of additional complementary
products, technologies or businesses.  Such acquisitions may
result in the diversion of our attention from the day-to-day
business operations and may include numerous other risks,
including:

  *    difficulties in the integration of the operations and
     products:

  *    integration and retention of personnel of the acquired
     companies; and

  *    financial risks,

Future acquisitions by us may result in:

*    dilutive issuances of equity securities;

*    the incurrence of additional debt;

*       reduction of existing cash balances; and

*    amortization expenses related to goodwill and other
  intangible assets and other charges to operations.

<BOLD>To service our substantial debt and make future
acquisitions, we will require a significant amount of cash.  Our
ability to generate cash and borrow on acceptable terms depends
on many factors beyond our control.</BOLD>

At March 31, 1999, our  bank debt was $26.1 million and our total
funded debt was $53.6 million.  Our future growth will depend in
part on additional acquisitions and our ability to obtain
additional financing on acceptable terms.  We will from time to
time seek additional funding through public or private financing,
including equity or debt financing.  If additional funds are
raised by issuing equity securities, our stockholders may
experience dilution.  There can be no assurance that we will be
successful in securing additional financing or that adequate
funding will be available and, if available, will be on terms
that are acceptable to us.  Further, debt may continue to
increase and there can be no assurance that we will generate
sufficient cash flow to meet our principal and interest payment
obligations.

<BOLD>Our ability to sell products and services internationally
are subject to U.S. Government export controls that could
prevent, or significantly delay, our making international sales.
</BOLD>

We have recently placed greater emphasis on international sales
and have increased marketing expenses in order to compete in
international markets.   Our products and services are subject to
export control regulations of the U.S. Government.  In most
instances a specific export license is required for the sale of
our products and services directly to international customers.
Failure to receive, or a delay in receiving, these export
licenses would greatly limit our ability to increase sales.
Direct sales to foreign governments and international customers
were  12.8% of total sales in fiscal 1999.

<PAGE 7>



<BOLD>In addition to competing against large defense contractors
with greater financial resources we also have many small
competitors that receive certain preference in bidding for which
we do not qualify.</BOLD>

The defense industry is dominated by several large companies, all
of whom have much greater resources than we have.  These
competitors include the Boeing Company, Lockheed Martin
Corporation, Raytheon Company, GEC-Marconi Hazeltine Corporation,
Northrop Grumman Corporation, United Industrial Corporation,
Unisys Corporation, Computer Sciences Corporation, TRW, Inc., and
Condor Systems, Inc.  The size and reputation of many of these
companies may give them an advantage in competing for contracts.
We also compete with several small companies that can sometimes
take advantage of special government programs, such as small
business and small disadvantaged business set-asides whereby
competition is limited to qualifying small and small
disadvantaged businesses.  In fiscal 1998 and earlier, we were
able to qualify for small business status when the standard used
was 750 employees or less.  As a result of our acquisition of PRB
Associates, Inc. in May 1998, our total number of employees
increased to approximately 900, which is likely to result in our
not qualifying for small business status in most circumstances,
except where that standard used is 1,500 employees or less. As a
result of the acquisition of Amherst Systems, Inc., we now have
approximately 1,200 employees.  Since we no longer qualify for
these bidding preferences, our competitive bidding position has
been affected and, in certain instances makes it more difficult
for us to win new contracts.

<BOLD>The debentures are subordinated to our current senior
indebtedness and all of future senior indebtedness.</BOLD>

The debentures are expressly subordinated in right of payment to
all of our existing and future senior indebtedness, which
includes current and future borrowing under our bank line of
credit recently increased to $27.0 million.  As of March 31, 1999
our  senior indebtedness was $26.1 million.  Neither the
provisions of the indenture nor the debentures limit our ability
to incur additional senior indebtedness or other indebtedness.
The indenture and the debentures do not contain any financial
covenants or similar restrictions on us.  Therefore, the holders
of the debentures will have no protection, other than rights upon
"Events of Default" as described under "Description of
Debentures," from adverse changes in our financial condition. In
the event of insolvency, bankruptcy, liquidation, reorganization,
dissolution or winding up of our business or upon our default in
payment with respect to any indebtedness our assets will be
available to pay the amounts due on the debentures only after all
senior indebtedness has been paid in full.

<BOLD>A failure of our computer programs, or the computer
programs of our customers or suppliers, to correctly recognize
the Year 2000 could have a material adverse impact on our
business.</BOLD>

Numerous business publications and government reports have
alerted businesses and investors to the potential adverse impact
of computer programs failing to correctly recognize the Year
2000, a situation commonly referred to as the "Year 2000 Issue"
or the "Year 2000 Problem."  We believe we are adequately
addressing modification or replacement of our internal operating
systems and our products.  We do not currently anticipate that we
will incur material expenditures to complete any such
modification or replacement because we believe that a majority of
our systems and products are Year 2000 compliant, although there
can be no assurance in this regard.  A failure of suppliers or
customers to successfully address the Year 2000 Issue, however,
could have a material adverse impact on our business, financial
condition or results of operations.  The Department of Defense
and its agencies are our largest customer group, representing
87.2% of our  fiscal 1999 net sales.  A failure by the Department
of Defense to adequately address the Year 2000 Problem could,
among other things, result in payment delays and contract
administration delays which may result in a need for increased
borrowing and interest expense to satisfy our operational and
capital expenditure needs.

<PAGE 8>

<BOLD>There is currently no liquid market for the debentures and,
since we do not intend to list the debentures on any exchange, we
do not anticipate one will develop.</BOLD>

There has been no public market for the debentures, and we
believe it is unlikely that an active or liquid trading market
will develop or be sustained.

       <ITALIC> <BOLD>Forward-Looking Information</BOLD>

This prospectus includes "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995.
This Act provides a "safe harbor" for forward-looking statements
to encourage companies to provide prospective information about
themselves so long as they identify these statements as forward-
looking and provide meaningful cautionary statements identifying
important factors that could cause actual results to differ from
the projected results.  All statements other than statements of
historical fact we make in the prospectus or in any document
incorporated by reference are forward-looking.  In particular,
the statements herein regarding industry prospects and our future
results of operations or financial position are forward-looking
statements.  Forward-looking statements reflect our current
expectations and are inherently uncertain.  Our actual results
may differ significantly from our expectations.  The above
section entitled "Risk Factors" describes some, but not all, of
the factors that could cause these differences.

            <BOLD>Use Of Proceeds</BOLD></ITALIC>

Comptek will not receive any proceeds from the sale by any
selling security holder of the debentures or the underlying
common stock.

              <BOLD><ITALIC>Ratio Of Earnings To Fixed
                     Charges</BOLD></ITALIC>

The ratio of earnings to fixed charges for each of the periods
indicated is as follows:


                  Fiscal Year Ended March 31,
                       1995  1996   1997   1998   1999
Ratio of
 Earnings               -      -    4.1x   5.5x   3.2x
 (loss) to
 fixed charges
 .

In fiscal 1994, 1995 and 1996 fixed charges exceeded earnings by
$7.5 million, $1.1 million and $8.3 million, respectively.

For these ratios, "earnings (loss)" represents income or loss
before taxes plus fixed charges.  Fixed charges consist of
interest expense, including amortization of debt issuance costs,
and that portion of rental expense we believe to be
representative of interest.

         <BOLD><ITALIC>Recent Developments</BOLD></ITALIC>

In March 1999, we sold $15 million of 8 1/2% convertible
subordinated debentures in a private placement pursuant to
Regulation D under the Securities Act.  We used the net proceeds
of the sale, approximately $13.8 million, as part of the purchase
price of our acquisition of the business operations and related
assets and liabilities of Amherst Systems, Inc. We paid a
purchase price of $30 million and assumed long-term debt of $5.1
million.  We paid the purchase price by delivering to Amherst
Systems $20 million in cash and $10 million in subordinated
promissory notes of Comptek.  These promissory notes, which
mature

<PAGE 9>
on March 26, 2001, bear interest at the rate of 5.5% per year
compounded annually, payable at maturity.  The promissory notes
are unsecured and subordinated to Comptek's senior indebtedness
and the debentures.  At maturity, however, the promissory notes
may be replaced by indebtedness which would be senior to the
debentures.

Amherst Systems is a manufacturer of computer controlled
simulation/stimulation equipment and systems which are used to
test military avionics equipment including radar warning
receivers, radar counter-measures equipment, radars, and infrared
sensor systems.  These systems are also used to train electronic
warfare systems operators.  Amherst Systems also produces
receiver systems used to verify simulation environments.  Amherst
Systems has expertise in the development of large computer
programs for real-time processing, the design of high speed
digital processing hardware, the generation of embedded software
for digital signal processors, the development of wide band
microwave systems, and the development of microwave components.
Amherst Systems has experienced growth in its systems sales as
the systems it tests have grown more accurate and complex
necessitating a corresponding increase in the sophistication of
the Amherst Systems test equipment.  Other factors driving growth
include the increase in sales of new products ranging from
portable units to very large systems installed in test
facilities, systems integration work and sales to overseas
customers.  Sales for the eight months ended December 31, 1998
and for the fiscal year ended April 30, 1998, were $29.2 million
and $31.6 million, respectively.  Amherst Systems customers
include the U.S. Air Force, Navy, and Army and major aerospace
prime contractors such as Lockheed, Boeing, and Northrop Grumman.
Amherst Systems' contract backlog as of March 31, 1999 was $63.7
million, of which $57.2 million was funded.

(1)  Gives effect to the acquisition of the business operations
  of Amherst Systems and the sale of debentures, as if the
  acquisition and the sale had occurred on December 25, 1998.  No
  pro forma effect has been given to the acquisition of PRB
  Associates because Comptek's December 25, 1998 historical
  consolidated balance sheet already reflects such acquisition.

<PAGE 11>

      <BOLD><ITALIC>Description Of Debentures</BOLD></ITALIC>

The 8 1/2% convertible subordinated debentures  were issued under
an indenture, dated as of March 24, 1999, between Comptek and The
Bank of New York, as the trustee under the indenture.  The terms
of the debentures include those stated in the indenture and those
made a part of the indenture by reference to the Trust Indenture
Act of 1939.

The summary of the material terms of the debentures and the
indenture , a form of each is included as an exhibit to the
registration statement, is qualified by reference to the detailed
provisions of the debenture and the indenture, including the
definitions of certain terms to which we make reference in this
summary.

<BOLD>General</BOLD>

   The debentures are unsecured general obligations of Comptek,
subject to the rights of holders of our senior indebtedness, and
convertible into our common stock as described under "Conversion
Rights" below.  The debentures have been issued only in
denominations of $1,000 and multiples thereof and will mature on
April 1, 2004. The debentures bear interest payable semiannually
on April 1 and October 1 of each year, commencing October 1,
1999, at the per annum rate of 8 1/2%.  The first payment will be
for the period from the date of delivery to October 1, 1999.  We
will pay interest on the debentures to the persons who are
registered holders of debentures at the close of business on the
September 15 or March 15 preceding the applicable interest
payment date.  Principal (and premium, if any) and interest will
be payable, the debentures will be convertible and exchangeable,
and transfers thereof will be registrable, at the office or
agency of Comptek maintained for such purposes, initially at the
offices of the trustee.  We may pay principal and interest by
check and may mail an interest check to a holder's registered
address.  Holders must surrender debentures to a paying agent to
collect principal payments.

Initially, The Bank of New York will act as paying agent,
registrar and conversion agent.  We may change any paying agent,
registrar, conversion agent or co-registrar upon prior written
notice to the trustee and may act in any such capacity ourselves.

<BOLD>Form of Debentures</BOLD>

   The debentures are in fully registered form without coupons in
denominations of $1,000 or any multiples thereof.  A holder may
transfer or exchange debentures in accordance with the indenture.
No service charge will be made for any registration or transfer,
exchange or conversion of debentures, except for any tax or other
governmental charges that may be imposed in connection therewith.
The registrar need not transfer or exchange any debentures
selected for redemption.  Also, in the event of a partial
redemption, the registrar need not transfer or exchange any
debentures for a period of 15 days before selecting debentures to
be redeemed.  Except as described in "Certain Rights to Require
Repurchase of Debentures by the Company" below, the indenture
does require us to repurchase the debentures in the event of a
leveraged buyout, recapitalization or similar restructuring of
Comptek, even though our credit worthiness and the market value
of the debentures may decline significantly as a result of such
transaction.  The indenture does not protect holders of the
debentures against any decline in our credit quality.  The
registered holder of a debenture may be treated as its owner for
all purposes.

<BOLD>Conversion Rights</BOLD>

The holders of the debentures are entitled at any time prior to
maturity, subject to prior redemption, to convert the debentures
or portions thereof (which are $1,000 or multiples thereof) into
shares of our common stock at the conversion price of $9.50 per
share subject to adjustments as described below.  No payment or
adjustment will be made for accrued interest on a converted
debenture.  If any debenture not

<PAGE 12>

called for redemption is converted between a record date for the
payment of interest and the next succeeding interest payment
date, the relevant debenture must be accompanied by funds equal
to the interest payable to the registered holder on the next
interest payment date on the principal amount to be converted.
We will not issue fractional interests in shares of common stock
upon conversion of the debentures and instead will deliver a
check for the fractional share based upon the market value of the
common stock on the last trading date prior to the conversion
date.  If the debentures are called for redemption, conversion
rights will expire at the close of business on the redemption
date, unless we default in payment due upon such redemption.

The conversion price is subject to adjustments in certain events,
including:

  *    the payment of dividends or distributions on our common
     stock in shares of capital stock;

  *    subdivisions or combinations of our common stock into a
     greater or smaller number of shares of common stock;

  *    reclassification of the shares of our common stock resulting
     in an issuance of any shares of our capital stock;

  *    distribution of rights or warrants to all holders of our
     common stock entitling them to purchase common stock at less than
     the then current price at that time; and

  *    the distribution to all holders of common stock of assets,
     excluding certain cash dividends and distributions, or debt
     securities or any rights or warrants to purchase securities of
     Comptek; provided, however, that no adjustment will be required
     if holders of the debentures receive notice of and are allowed to
     participate in such transactions.

   No adjustment will be required for rights to purchase common
stock pursuant to a plan we establish for reinvestment of
dividends or interest, or for a change in the par value of the
common stock.  To the extent that debentures become convertible
into cash, no adjustment will be required thereafter as to cash.
We do not have to adjust the conversion price unless the
adjustment would be at least 1.0% in the conversion price;
however, any adjustment that would otherwise be required to be
made shall be carried forward and taken into account in any
subsequent adjustment.  We may voluntarily reduce the conversion
price for a period of time.

The conversion price shall also be adjusted downward to $8.50 (or
such other amount reflecting a 10.5% reduction to the then
current conversion price if an adjustment to the conversion price
had previously been made pursuant to the provisions outlined
above) if we report income before extraordinary item and
accounting change diluted earnings per share of less than $0.80
for our fiscal year ending March 31, 2000.  This adjustment would
take effect, if at all, at 8:00 a.m. as of the next business day
following the day on which we filed our Annual Report on Form 10-
K for the fiscal year ending March 31, 2000.

If we:

  *    pay dividends on our common stock in shares of capital
     stock;

  *    subdivide or combine the common stock;


  *    issue by reclassification of our common stock any shares of
     our capital stock; or

<PAGE 13>

  *    merge with, or transfer or lease substantially all of our
     assets to, another corporation or trust

The holders of the debentures then outstanding will be entitled
to convert their debentures into the kind and amount of shares of
capital stock, other securities, cash or other assets which they
would have owned immediately if they had converted their
debentures before the effective date of the transaction.

Any debentures called for redemption, unless surrendered for
conversion on or before the close of business on the redemption
date, are subject to being purchased from the holder of such
debentures at the redemption price by one or more investment
banks or other purchasers who may agree with us to purchase such
debentures and convert them into Comptek's common stock.

<BOLD>Penalty For Late Delivery of Conversion Shares</BOLD>

   Holders of the debentures will be entitled to receive a
penalty payment from us if, upon delivering a properly executed
conversion notice and the debenture to be converted, we fail to
deliver, or cause to be delivered, the shares of our common stock
for which the debenture is being converted within three business
days after delivery of the conversion notice and the debentures.
The penalty payment will apply to the period beginning on the
business day after delivery was due and ending on the day we
actually make delivery.   The penalty payment would accrue at a
rate of 0.50% of the principal amount of the debentures.

<BOLD>Subordination of Debentures</BOLD>

   The indebtedness evidenced by the debentures is subordinated
and junior in right of payment to the prior payment in full of
all of our senior indebtedness. We will not pay principal of (or
premium if any) or interest on the debentures, if there shall
have occurred and be continuing a default with respect to any of
our senior indebtedness, unless and until such default or event
of default shall have been cured or waived or shall have ceased
to exist.

Upon any acceleration of the principal of the debentures or any
distribution of our assets upon any receivership, dissolution,
winding-up, liquidation, reorganization or similar proceedings of
Comptek, whether voluntary or involuntary, or in bankruptcy or
insolvency, all amounts due or to become due upon all senior
indebtedness must be paid in full before the holders of the
debentures or the trustee are entitled to receive or retain any
of our assets.  Because of this provision, in the event of
insolvency, holders of the debentures may recover less, ratably,
than holders of senior indebtedness.

"Senior indebtedness" is the principal, premium, if any, interest
on and all other amounts payable under or in respect of  our
indebtedness, other than indebtedness owed to one of our
subsidiaries, indebtedness which is expressly pari passu with the
debentures or indebtedness which is expressly subordinated to the
debentures.   There is no limit on the amount of senior
indebtedness that we may incur.

<PAGE 14>

<BOLD>Optional Redemption</BOLD>

   At our option we may redeem the debentures, as a whole or in
part, at any time or from time to time commencing on or after
March 1, 2002.   We must give holders of the debentures at least
30 days' and not more than 60 days' prior notice by mail.  The
redemption prices  as a percentage of principal amount, are as
follows for the 12-month period beginning on or after March 1 of
the following years:

                                        Redemption
               Year                       Price

               2002                       103.4%
               2003                       101.7%
               2004 and thereafter        100.0%

<BOLD>Certain Rights to Require Repurchase of Debentures by the
Company</BOLD>

   In the event of any Change in Control (as described below) of
Comptek occurring on or prior to maturity, each holder of
debentures will have the right, to require us to repurchase all
or any part of such holder's debentures.  We would have to
repurchase the debentures 75 days after the date we give notice
of the Change in Control at a price equal to 101.0% of the
principal amount, together with accrued and unpaid interest to
the date of repurchase.  On or prior to the date of repurchase,
we would be required to deposit with the trustee or a paying
agent an amount of money sufficient to pay the repurchase price
of the debentures that are to be repaid on the date of
repurchase.

Our failure to repurchase the debentures  under these
circumstances, would result in an event of default under the
indenture, whether or not such repurchase is permitted by the
subordination provisions of the indenture.

On or before the 15th day after the occurrence of a Change in
Control, we would be obligated to mail to all holders of the
debentures a notice of:

  *    the event constituting and the date of such Change in
     Control,

  *    the date on which the repurchase will be made,

  *    the date by which the repurchase right must be exercised,

  *    the repurchase price for debentures, and

  *    the procedures that a holder must follow to exercise a
     repurchase right.

To exercise the repurchase right, a holder of a debenture must
deliver, on or before the 10th day prior to the date of
repurchase, written notice to us (or an agent designated by us
for such purpose) and to the trustee of the holder's desire to
exercise the right, together with the certificates evidencing the
debentures, duly endorsed for transfer.

<PAGE 15>

A "Change in Control" will occur when:

     (1)  all, or substantially all, of Comptek's assets are sold as
       an entirety to any person or related group of persons;

     (2)  there shall be consummated any consolidation or merger of
       Comptek

          (A)  in which Comptek is not the continuing or surviving
            corporation (other than a consolidation or merger with a wholly-
            owned subsidiary of Comptek in which all common shares
            outstanding immediately prior to the effectiveness thereof are
            changed into or exchanged for the same consideration) or

          (B)  pursuant to which the common stock is converted into cash,
            securities, other property, in each case other than a
            consolidation or merger of Comptek in which the holders of the
            common stock immediately prior to the consolidation or merger
            have, directly or indirectly, at least a majority of the common
            stock of the continuing or surviving corporation immediately
            after such consolidation or merger; or

     (3)  any person, or any persons acting together that would
       constitute a "group" for purposes of Section 13(d) of the
       Exchange Act, together with any affiliates thereof, acquires
       beneficial ownership (as defined in Rule 13d-3 under the Exchange
       Act) of at least 50.0% of the total voting power of all classes
       of capital shares of Comptek entitled to vote generally in the
       election of directors of Comptek.

Notwithstanding clause (3) above, a Change in Control will not be
deemed to have occurred solely by virtue of Comptek; any
subsidiary; any employee share purchase plan, share option plan,
or other share incentive plan or program; retirement plan or
automatic dividend reinvestment plan; or any substantially
similar plan of Comptek or any subsidiary or any person holding
our securities for or pursuant to the terms of any such employee
benefit plan, filing or becoming obligated to file a report under
or in response to Schedule 13D or Schedule 14D-1 (or any
successor schedule, form, or report) under the Exchange Act, as
amended, disclosing beneficial ownership by it of shares or
securities of Comptek, whether at least 50.0% of the total voting
power referred to in clause (3) above or otherwise.  A
recapitalization or a leveraged buyout or similar transaction
involving members of management or their affiliates will
constitute a Change in Control if it meets the foregoing
definition.

Notwithstanding the foregoing, a Change in Control as described
above will not be deemed to have occurred if:

  *    the current market price of the common stock on the date of
     a Change in Control is at least equal to 105.0% of the conversion
     price of the debentures in effect immediately preceding the time
     of such Change in Control;

  *    all of the consideration (excluding cash payments for
     fractional shares) in the transaction giving rise to such Change
     in Control to the holders of common stock consists of shares of
     common stock that are, or immediately upon issuance will be,
     listed on a national securities exchange or quoted on the Nasdaq
     National Market, and as a result of such transaction the
     debentures will become convertible solely into such shares of
     common stock;  or

  *    the consideration in the transaction giving rise to such
     Change in Control to the holders of common stock consists of cash
     or securities that are, or immediately upon issuance will be,
     listed on a national securities exchange or quoted on the Nasdaq
     National Market, or a

  <PAGE 16>

     combination of cash and such securities, and the aggregate
     fair market value of such consideration (which, in the case
     of such securities, will be equal to the average of the
     daily closing prices of such securities during the 10
     consecutive trading days commencing with the sixth trading
     day following consummation of such transaction) is at least
     105.0% of the conversion price of the debentures in effect
     on the date immediately preceding the closing date of such
     transaction.

   There is no definition of the phrase "all or substantially
all" as applied to our assets and used in the definition of
Change in Control in the indenture, and there is no clear
definition of the phrase under applicable law.  As a result of
the uncertainty of the meaning of this phrase, in the event we
were to sell a significant amount of our assets, the holders and
us may disagree over whether the sale gives rise to the right of
holders to require us to repurchase the debentures.  In that
event, the holders would likely not be able to require us to
repurchase unless and until the disagreement were resolved in
favor of the holders.

The right to require us to repurchase debentures as a result of a
Change in Control could create an event of default under senior
indebtedness.  As a result, any repurchase could, absent a
waiver, be blocked by the subordination provisions of the
debentures.  See "Subordination of  Debentures" above.  Our
ability to pay cash to the holders upon a repurchase may also be
limited by certain financial covenants contained in our senior
indebtedness.

In the event a Change in Control occurs and the holders exercise
their rights to require us to repurchase debentures, we intend to
comply with applicable tender offer rules under the Exchange Act,
including Rules 13e-4 and 14e-1, as then in effect, with respect
to any such purchase.  The Change in Control purchase feature of
the debentures may in certain circumstances make more difficult
or discourage a takeover of Comptek.  The Change in Control
purchase feature, however, is not the result of management's
knowledge of any specific effort to accumulate common stock or to
obtain control of Comptek, or part of a plan by management to
adopt a series of anti-takeover provisions.  Instead, the Change
in Control purchase feature is a standard term contained in other
similar debt securities.

The foregoing provisions would not necessarily afford holders of
debentures protection in the event of highly leveraged or other
transactions involving Comptek that may adversely affect holders
of debentures.

<BOLD>Modification of the Indenture</BOLD>

Under the indenture, with certain exceptions, our rights and
obligations with respect to the debentures and the rights of
holders of the debentures may only be modified by us and the
trustee with the written consent of the holders of not less than
66-2/3% in principal amount of the outstanding debentures.
However, without the consent of each holder of any debenture
affected, an amendment, waiver or supplement may not:

     (a)  reduce the amount of debentures whose holders may consent to
          an amendment;

     (b)  reduce the rate or change the time of payment of interest on
          any debenture;

     (c)  reduce the principal of or change the fixed maturity of any
          debenture;

     (d)  make any debenture payable in money other than that stated
          in the debenture;

     (e)  change the provisions of the indenture regarding the right
          of the holders of a majority of the debenture to waive defaults
          under the indenture or impair the right of any holder of
          debentures to institute suit for the enforcement of any payment
          of principal and interest on the debentures on and after their
          respective due dates;

<PAGE 17>

     (f)  make any change that adversely affects the right to convert
          any debenture;

     (g)  make any change to the subordination or seniority of the
          debentures that adversely affects the rights of any holder; or

     (h)  impair the right, as limited in the indenture, of any holder
          to institute any suit or proceeding.

<BOLD>Events of Default, Notice and Waiver</BOLD>

The following are "Events of Default" under the indenture with
     respect to the debentures:

     (a)  default in the payment of interest on the debentures when
          due and payable which continues for 30 days;


     (b)  default in the payment of principal of (and premium, if any,
          on) the debentures when due and payable, at maturity, upon
          redemption or otherwise;

     (c)  our failure to perform any other covenant contained in the
          indenture or the debentures which continues for 60 days after
          notice as provided in the indenture;

     (d)  acceleration of any indebtedness for money borrowed
          (including obligations under leases required to be capitalized on
          the balance sheet of the lessee under generally accepted
          accounting principles but not including any indebtedness or
          obligation for which recourse is limited to property purchased)
          in an aggregate principal amount in excess of $20.0 million,
          whether existing on the date of the execution of the indenture or
          thereafter created, if such indebtedness is not paid or such
          acceleration is not annulled within ten days after notice to us
          of such acceleration; and

     (e)     certain events of bankruptcy, insolvency or
          reorganization relating to us.

If an Event of Default occurs and is continuing with respect to
the debentures, either the trustee or the holders of at least a
majority in principal amount of the debentures may declare all of
the debentures to be due and payable immediately.

   If any Events of Default have occurred and are continuing or
would exist immediately after giving effect to such action, we
will not (i) declare or pay any dividends or make any
distribution to holders of our capital stock or (ii) purchase,
redeem or otherwise acquire or retire for value any of our common
stock, or any warrants, rights or options, to purchase or acquire
any shares of our common stock (other than the debentures or any
other convertible indebtedness of ours that is neither secured
nor subordinated to the debentures).

The trustee may require indemnity reasonably satisfactory to it
before it enforces the indenture or the debentures. Subject to
certain limitations, holders of a majority in principal amount of
the debentures may direct the trustee in its exercise of any
trust or power.  The trustee may withhold from holders of the
debentures notice of any default (except a default in payment of
principal or interest) if it determines that withholding notice
is in their interests.  We are required to file with the trustee
annually an officer's statement as to the absence of defaults in
fulfilling any of its obligations under the indenture.

No consent of the holders of the debentures is required for (1)
Comptek to consolidate with or merge into or transfer or lease
substantially all of its assets to another corporation or trust
which assumes the

<PAGE 18>

obligations of Comptek under the indenture and debentures or  (2)
for any reorganization within the meaning of Section 368(a)(1)(B)
of the Internal Revenue Code of 1986, as amended; no consent of
holders of the debentures required for any amendment of the
indenture or the debentures by Comptek or the trustee to:

  *    cure any ambiguity, defect or inconsistency, or to provide
     for uncertificated debentures in addition to certified
     debentures, or

  *    to make any change that does not adversely affect the right
     of a holder of a debenture.

<BOLD>Consolidation, Merger, Sale or Conveyance</BOLD>

   The indenture provides that Comptek may not merge or
consolidate with, or sell or convey all, or substantially all, of
its assets to another person unless:

  *    such person is a company or a trust;

  *    such person assumes by supplemental indenture all the
     obligations of Comptek under the debentures and the indenture;
     and

  *    immediately after the transaction no default or Event of
     Default shall exist.

<BOLD>Marketability</BOLD>

At present there is no public market for the debentures, and it
is not likely that a market will develop. The debentures were
initially sold pursuant to exemptions from registration under the
Securities Act.  We filed a registration statement under the
Securities Act relating to the resale of the debentures and the
underlying shares of common stock.  However, there can be no
assurance that we will be able to maintain the effectiveness of
the current registration statement as required.  The absence of
such an effective registration statement may limit any holder's
ability to sell the debentures or the underlying shares of common
stock or could adversely affect the price at which the debentures
or the underlying shares of common stock can be sold.

<BOLD>Governing Law</BOLD>

The indenture and the debentures are governed by and construed in
accordance with the laws of the State of New York.

<BOLD>Registration Rights Agreement</BOLD>

Pursuant to a registration rights agreement entered into by us in
connection with the initial sale of the debentures, the
debentures and the underlying shares of common stock have been
registered under the Securities Act with the SEC.  We have also
agreed to prepare and file such amendments and supplements to the
registration statement as may be necessary to keep the
registration statement effective until :

  *       Two years from the effective date of the registration
     statement, or

  *    Such shorter period when all the debentures and the shares
     of common stock offered hereby have been sold thereby, or

<PAGE 19>

  *    Until the debentures and the Conversion Shares are no
     longer, by reason of Rule 144 promulgated under the Securities
     Act or any other rule of similar effect, required to be
     registered for the sale thereof.

              <BOLD>Selling Security Holders</BOLD>

The debentures were originally issued by  us and sold to the
initial purchasers in  transactions exempt from the registration
requirements of the Securities Act.   We reasonably believed that
each such person was an "accredited investors," as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act. Selling
security holders ( may from time to time offer and sell pursuant
to this prospectus any or all of the debentures and common stock
into which the debentures are convertible. The term "selling
security holders" includes their transferees, pledgees or donees
or their successors

The following table sets forth information, as of June 16, 1999,
with respect to the selling security holders and the respective
principal amounts of debentures beneficially owned by each  that
may be offered pursuant to this prospectus.  The information is
based on information provided by or on behalf of the selling
security holders.  The selling security holders may offer all,
some or none of the debentures or common stock into which the
debentures are convertible.  Because the selling security holders
may offer all or some portion of the debentures or the common
stock, no estimate can be given as to the amount of the
debentures or the common stock that will be held by the selling
security holders upon termination of any such sales.  In
addition, the selling security holders identified below may have
sold, transferred or otherwise disposed of all or a portion of
their debentures since the date on which they provided the
information regarding their debentures in transactions exempt
from the registration requirements of the Securities Act.

None of the selling security holders has had any material
relationship with Comptek or its affiliates within the past three
years.  The selling security holders purchased all of the
debentures in a private transactions exempt from the registration
requirements of the Securities Act.  All of the debentures were
"restricted securities" under the Securities Act prior to this
registration.

The selling security holders have represented to us that they
purchased the debentures for their own account for investment
only and not with a view toward selling or distributing them,
except pursuant to sales registered under the Securities Act or
exemptions.  Comptek agreed with the selling security holders to
file the registration statement to register the resale of the
debentures and the underlying shares of common stock.  Comptek
agreed to prepare and file all necessary amendments and
supplements to the registration statement to keep it effective
until the earlier of (1) two years from the effective date of the
registration statement and (2) the date on which the debentures
and the common stock into which the debentures are convertible no
longer qualify as "Registrable Securities" under the Registration
Rights Agreement.

Information concerning the selling security holders may change
from time to time and any such changed information will be set
forth in supplements to this prospectus if and when necessary.
In addition, the per share conversion price, and, therefore, the
number of shares of common stock issuable upon conversion of the
debentures, is subject to adjustment under certain circumstances.
Accordingly, the aggregate principal amount of debentures and the
number of shares of common stock into which the debentures are
convertible may increase or decrease.

                <BOLD>Plan Of Distribution</BOLD>

The selling security holders and their successors  may sell the
debentures and the common stock into which the debentures are
convertible directly to purchasers or through underwriters,
broker-dealers or agents, who may receive compensation in the
form of discounts, concessions or commissions from the selling
security holders.   These discounts, concessions or commission as
to any particular underwriter, broker-dealer or agent may be in
excess of those customary in the types of transactions involved.

The debentures and the common stock into which the debentures are
convertible may be sold in one or more transactions:
  *    at fixed prices;

  *    at prevailing market prices at the time of sale;

  *    at prices related to such prevailing market prices;

  *    at varying prices determined at the time of sale; or

  *    at negotiated prices.

Such sales may be effected in transactions; which may involve
crosses or block transactions:

     (1)  on any national securities exchange or quotation service on
          which the debentures or the common stock may be listed or quoted
          at the time of sale;

     (2)  in the over-the-counter market;

     <PAGE 21>

     (3)   in transactions otherwise than on such exchanges or
          services or in the over-the-counter market;

     (4)   through the writing of options  (whether such options are
          listed on an options exchange or otherwise); or

     (5)   through the settlement of short sales.

In connection with the sale of the debentures and the common
stock into which the debentures are convertible or otherwise, the
selling security holders may enter into hedging transactions with
broker-dealers or other financial institutions which may in turn
engage in short sales of the debentures or the common stock into
which the debentures are convertible and deliver these securities
to close out such short positions, or loan or pledge the
debentures or the common stock into which the debentures are
convertible to broker-dealers that in turn may sell these
securities.

The aggregate proceeds to the selling security holders from the
sale of the debentures or common stock into which the debentures
are convertible offered by them hereby will be the purchase price
of such debentures or common stock less discounts and
commissions, if any.  Each of the selling security holders
reserves the right to accept and, together with their agents from
time to time, to reject, in whole or in part, any proposed
purchase of debentures or common stock to be made directly or
through agents.  We will not receive any of the proceeds from
this offering.

Our common stock is listed on the American Stock Exchange.  We do
not intend to list the debentures for trading on any national
securities exchange or on the Nasdaq National Market and can give
no assurance about the development of any trading market for the
debentures.

In order to comply with the securities laws of some states, if
applicable, the debentures and common stock into which the
debentures are convertible may be sold in such jurisdictions only
through registered or licensed brokers or dealers.  In addition,
in some states the debentures and common stock into which the
debentures are convertible may not be sold unless they have been
registered or qualified for sale or an exemption from
registration or qualification requirements is available and is
complied with.

   Both Warburg Pincus Emerging Growth Fund and Joseph Stechler &
Company, Incorporated are affiliated with a registered broker-
dealer and because of such affiliation will be "underwriters"
within the mening of Section 2(11) of the Securities Act.  Each
of  the other selling security holders and any underwriters,
broker-dealers or agents that participate in the sale of the
debentures and common stock into which the debentures are
convertible may be "underwriters" within the meaning of Section
2(11) of the Securities Act.  Any discounts, commission,
concessions or profit they earn on any resale of the shares may
be underwriting discounts and commissions under the Securities
Act.  Selling security holders who are "underwriters" within the
meaning of Section 2(11) of the Securities will be subject to the
prospectus delivery requirements of the Securities Act.  The
selling security holders have acknowledged that they understand
their obligations to comply with the provisions of the Exchange
Act and the rules thereunder relating to stock manipulation,
particularly Regulation M, and have agreed that they will not
engage in any transaction in violation of such provisions.

In addition, any securities covered by this prospectus which
qualify for sale pursuant to Rule 144 of the Securities Act may
be sold under Rule 144 rather than pursuant to this prospectus.
A selling security holder may not sell any debentures or common
stock described herein and may not transfer, devise or gift such
securities by other means not described in this prospectus.

<PAGE 22>

To the extent required, the specific debentures or common stock
to be sold, the names of the selling security holders, the
respective purchase  prices and public offering prices, the names
of any agent, dealer or underwriter, and any applicable
commissions or discounts with respect to a particular offer will
be set forth in an accompanying prospectus supplement or, if
appropriate, a post-effective amendment to the registration
statement of which this prospectus is a part.

The Registration Rights Agreement provides for cross-
indemnification of the selling security holders and Comptek and
their respective directors, officers and controlling persons
against certain liabilities in connection with the offer and sale
of the debentures and the common stock, including liabilities
under the Securities Act.  Comptek will pay substantially all of
the expenses incurred by the selling security holders and Comptek
incident to the offering and sale of the debentures and the
common stock, provided that each selling holder will be
responsible for payment of commission, concessions and discounts
of underwriters, broker dealers or agents.

                   <BOLD>Legal Matters</BOLD>

The validity of the debentures and shares of common stock offered
hereby will be passed upon by Christopher A. Head,  General
Counsel for Comptek.  Mr. Head is an executive officer of

<BOLD>Item 15. Indemnification of Directors and Officers.</BOLD>

Article IX. of the Company's By-laws provides as follows:

     Every person who is or was a director, officer or
     employee of the corporation, or of any other
     corporation which he served as such at the request of
     the corporation, may in accordance with the second
     paragraph of this Article IX be indemnified by the
     corporation against any and all liability and
     reasonable expense that may be incurred by him in
     connection with or resulting from any claim, action,
     suit or proceeding (whether brought by or in the right
     of the corporation or such other corporation or
     otherwise), civil or criminal, or in connection with an
     appeal relating thereto, in which he may be involved,
     as a party or otherwise, by reason of his being or
     having been a director, officer or employee of the
     corporation or such other corporation, or by reason of
     any action taken or not taken in his capacity as such
     director, officer or employee, whether or not he
     continues to be such at the time such liability or
     expense shall have been incurred, provided such person
     acted, in good faith, in a manner he reasonably
     believed to be in or not opposed to the best interests
     of the corporation or such other corporation, as the
     case may be, and, in addition in any criminal action or
     proceeding, had no reasonable cause to believe that his
     conduct was unlawful.  As used in this Article IX, the
     terms "liability" and "expense" shall include, but
     shall not be limited to, court costs, counsel fees and
     disbursements and amounts of judgements, fines or
     penalties against, and amounts paid in settlement by, a
     director, officer or employee.  The termination of any
     claim, action, suit or proceeding, civil or criminal,
     by judgment, settlement (whether with or without court
     approval), conviction or upon a pleas of guilty or nolo
     contendere, or its equivalent, shall not create a

     <PAGE 26>

     presumption that a director, officer or employee did
     not meet the standards of conduct set forth in this
     paragraph.

     Expenses incurred with respect to any claim, action,
     suit or proceeding of the character described in the
     first paragraph of this Article IX may be advanced by
     the corporation prior to the final disposition thereof
     upon receipt of any undertaking by or on behalf of the
     recipient to repay such amount unless it shall
     ultimately be determined that he is entitled to
     indemnification under this Article IX.

     The rights of indemnification provided in this Article
     IX shall be in addition to any other rights to which
     any such director, officer or employee may otherwise be
     entitled by contract, as a matter of law, by vote of
     the stockholders, or otherwise; and in the event of any
     such person's death, such rights shall extend to his
     heirs and legal representatives.

Paragraph TENTH of the Company's Certificate of Incorporation
provides as follows:

     TENTH: No director shall be personally liable to the
     Corporation or any shareholder for damages for any
     breach of duty as a director, except for (a) the
     liability of any director if a judgment or other final
     adjudication adverse to him establishes that (i) his
     acts or omissions were in bad faith or involved
     intentional misconduct or a knowing violation of law or
     (ii) he personally gained in fact a financial profit or
     other advantage to which he was not legally entitled or
     (iii) his acts violated Section 719 of the New York
     Business Corporation Law, or (b) the liability of any
     director for any act or omission prior to the adoption
     of this paragraph TENTH.  Any repeal or modification of
     this paragraph TENTH by the shareholders of the
     corporation shall not, unless otherwise required by
     law, adversely affect any right or protection of a
     director existing at the time of such repeal or
     modification with respect to acts or omissions
     occurring prior to such repeal or modification.  If the
     New York Business Corporation Law is amended after
     approval by the shareholders of this paragraph TENTH to
     authorize corporate action further eliminating or
     limiting the personal liability of directors, then the
     liability of a director of the corporation shall be
     eliminated or limited to the fullest extent permitted
     by New York Business Corporation Law, as amended from
     time to time.

Section 722 of the New York Business Corporation Law (the "BCL")
permits indemnification against judgments, fines and amounts paid
in settlement and reasonable expenses, including attorneys' fees,
actually and necessarily incurred as a result of legal actions or
proceedings.  Under Section 723 of the BCL, if a litigant is
successful in the defense of such an action or proceeding, he or
she is automatically entitled to indemnification.  Otherwise,
indemnification will depend upon whether or not the director or
officer has lived up to an appropriate standard of conduct in the
performance of his or her duties.

<BOLD>Item 17. Undertakings</BOLD>

I.   Rule 415 Offering.  The undersigned registrant hereby
undertakes:

     1.   To file, during any period in which offers or sales are
          being made, a post-effective amendment to this
          registration statement:

          (i)  To include any prospectus required by Section
               10(a)(3) of the Securities Act  of 1933;

          (ii) To reflect in the prospectus any facts or events
               arising after the effective date of the
               registration statement (or the most recent post-
               effective amendment thereof) which, individually
               or in the aggregate, represent a fundamental
               change in the information set forth in the
               registration statement.  Notwithstanding the
               foregoing, any increase or decrease in volume of
               securities offered (if the total dollar value of
               securities offered would not exceed that which was
               registered) and any deviation from the low or high
               end of the estimated maximum offering range may be
               reflected in the form of prospectus filed with the
               Commission pursuant to Rule 424(b), in the
               aggregate, the changes in volume and price
               represent no more than a 20% change in the maximum
               aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the
               effective registration statement.

          (iii)To include any material information with respect
               to the plan of distribution not previously
               disclosed in the registration statement or any
               material change to such information in the
               registration statement;

<PAGE 29>

               Provided, however, that paragraphs (i) and (ii)
               above do not apply if the information required to
               be included in a post-effective amendment by those
               paragraphs is contained in periodic reports filed
               by the registrant pursuant to Section 13 or
               Section 15(d) of the Securities Exchange Act of
               1934 that are incorporated by reference in this
               registration statement.

     2.   That for the purpose of determining any liability under
          the Securities Act of 1933, each such post-effective
          amendment shall be deemed to be a new registration
          statement relating to the securities offered pursuant
          to this registration statement, and the offering of
          such securities at that time shall be deemed to be the
          initial bona fide offering thereof.

     3.   To remove from registration by means of a post-
          effective amendment any of the securities being
          registered which remain unsold at the termination of
          the offering.

   II.    Acceleration of Effectiveness - Indemnification
     Undertaking.

     Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors,
     officers and controlling persons of the registrant pursuant
     to the provisions described under Item 15 above, or
     otherwise, the registrant has been advised that in the
     opinion of the Securities and Exchange Commission such
     indemnification is against public policy as expressed in the
     Act and is, therefore, unenforceable.  In the event that a
     claim for indemnification against such liabilities (other
     that than the payment by the registrant of expenses incurred
     or paid by a director, officer or controlling person of the
     registrant in the successful defense of any action, suit or
     proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being
     registered, the registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling
     precedent, submit to a court of appropriate jurisdiction the
     question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed
     by the final adjudication of such issue.

                          EXHIBIT 10.2

                     1994 STOCK OPTION PLAN
                               FOR
                     NON-EMPLOYEE DIRECTORS,
                           AS AMENDED


           ARTICLE 1 - ESTABLISHMENT, PURPOSE, AND DURATION

1.1   Establishment of the Plan.  Comptek Research, Inc., a New
      York corporation with its corporate headquarters located at
      2732 Transit Road, Buffalo, NY 14224 ("Comptek"), hereby
      establishes a stock option plan for non-employee members of
      its Board of Directors (the "Plan").  All options granted
      under the Plan will be Nonqualified Stock Options ("NQSO").

      Upon ratification by affirmative vote of a majority of
      Shares voting at Comptek's 1994 Annual Meeting of
      Shareholders, the Plan shall become effective as of
      December 10, 1993, (the "Effective Date") and shall remain
      in effect as provided in 1.3 herein.  Options may be
      granted prior to shareholder ratification of the Plan;
      provided, however, that in the event shareholder
      ratification of the Plan is not obtained at Comptek's 1994
      Annual Meeting of Shareholders, this Plan shall
      automatically terminate and all outstanding Options granted
      shall become null and void.

1.2   Purpose of the Plan.  The purpose of the Plan is to attract
      and retain the services of experienced and knowledgeable
      independent directors for the benefit of Comptek and its
      shareholders, and to encourage share ownership by members
      of the Board of Directors of Comptek who are not employees,
      in order to promote long-term shareholder value through
      ownership of common stock.

1.3   Duration of the Plan.  Subject to the right of the Board of
      Directors of Comptek to terminate the Plan at any time
      pursuant to Article 7 hereof, the Plan shall remain in
      effect until all Shares subject to the Plan shall have been
      purchased or acquired according to the Plan's provisions.
      However, in no event may an Option be granted under the
      Plan on or after December 9, 2003.


                       ARTICLE 2 - DEFINITIONS

Whenever used in the Plan, the following terms shall have the
meaning set forth below:

(a)   "Agreement" shall mean any written agreement, contract, or
      other instrument or document evidencing any Option granted
      pursuant to the Plan.

(b)   "Board" means the Board of Directors of Comptek Research,
      Inc., as constituted from time to time.

(c)   "Change in Control" means any of the following events:

      (i) The acquisition by any person (within the meaning of in
          Sections 13(d) or 14(d) of the Exchange Act) of
          beneficial ownership (within the meaning of Rule 13d-3
          promulgated under the Exchange Act) of thirty-three
          percent (33%) or more of the combined voting power of
          Comptek's then outstanding voting securities; or

      (ii)     The individuals who, as of the date hereof, are
          members of the Board (the "Incumbent Board"), cease for
          any reason to constitute a majority of the Board.  For
          purposes of this definition, if the election, or
          nomination for election by Comptek's shareholders, of
          any new Director was approved by a vote of a majority
          of the Incumbent Board, such new Director shall be
          deemed a member of the Incumbent Board; or

      (iii)     Approval by shareholders of Comptek of (a) a
          merger or consolidation involving Comptek if the
          shareholders of Comptek, immediately before such merger
          or consolidation, do not as a result of such merger or
          consolidation, own, directly or indirectly more than
          sixty-seven percent (67%) of the combined voting power
          of the then outstanding voting securities of the
          corporation resulting from such merger of consolidation
          in substantially the same proportion as their ownership
          of the combined voting power of the voting securities
          of Comptek outstanding immediately before such merger
          or consolidation, or (b) a complete liquidation or
          dissolution of Comptek or an agreement for the sale or
          other disposition of all or substantially all of the
          assets of Comptek.

      Notwithstanding the foregoing, a Change in Control shall
      not be deemed to occur pursuant to subsection (i), solely
      because thirty-three percent (33%) or more of the combined
      voting power of Comptek's then outstanding securities is
      acquired by (A) a trustee or other fiduciary holding
      securities under one or more employee benefit plans
      maintained by Comptek or any of its Subsidiaries or (B) any
      corporation which, immediately prior to such acquisition,
      is owned directly or indirectly by the shareholders of
      Comptek in the same proportion as their ownership of stock
      in Comptek immediately prior to such acquisition.

      Committee in good faith, upon receipt of sufficient
      competent medical advice from one or more individuals,
      selected by the Committee, who are qualified to give
      professional medical advice.

(h)   "Eligible Director" means a member of the Board who is not
      an employee of Comptek or any of its Subsidiaries.

(i)  "Exchange Act" means the Securities Exchange Act of 1934, as
      amended from time to time.

(j)   "Fair Market Value" of a Share of common stock shall be (i)
      the closing sale price of a Share of common stock as
      reported on the principal securities exchange on which
      Shares of common stock are then listed or admitted to

                      ARTICLE 3 - ADMINISTRATION


3.1   The Committee.  The Board shall appoint a committee to be
      known as the Directors' Stock Option Plan Committee (the
      "Committee"), which shall consist of at least three
      Directors to administer the Plan as contemplated by Rule
      16b-3 pursuant to the Exchange Act, or any successor or
      replacement rule.  Committee members shall receive no
      additional compensation for such service.  Eligible
      Directors who are eligible for options under the Plan may
      vote on matters affecting the administration of the Plan
      and may serve as members of the Committee.

3.2   Authority of the Committee.  The Committee shall have full
      power except as limited by law or by the Certificate of
      Incorporation or Bylaws of Comptek, and subject to the
      provisions herein, to administer the Plan, and to construe
      and interpret the Plan and any agreement or instrument
      entered into under the Plan.  The Committee, however, shall
      have no discretion with respect to the eligibility or
      selection of directors to receive Options under the Plan,
      the number of shares of stock subject to any such Options,
      of the Plan, or the purchase price thereunder, the vesting
      period, or the timing of Option grants  The Committee shall
      not have the authority to take any action which would
      result in the loss of eligibility of grants under the Plan
      for the "formula based" exemption under Rule 16b-
      3(c)(ii)(A) of the Exchange Act. The determination of the
      Committee in the administration of the Plan, as described
      herein, shall be final and conclusive and binding upon all
      persons including, without limitation, Comptek, its
      shareholders and persons granted options under the Plan.
      The Secretary of Comptek shall be authorized to implement
      the Plan in accordance with its terms and to take such
      actions of a ministerial nature as shall be necessary to
      effectuate the intent and purposes thereof.

3.3   No Guaranteed Term of Office.  Nothing in this Plan or any
      modification hereof, and no grant of an Option, or any term
      thereof, shall be deemed an agreement or condition
      guaranteeing to any Eligible Director any particular term
      of office or limiting the right of Comptek, the Board, or
      the shareholders to terminate the term of office of any
      Eligible Director under the circumstances set forth in the
      Comptek's Certificate of Incorporation or By-Laws, or as
      otherwise provided by law.


                ARTICLE 4 - SHARES SUBJECT TO THE PLAN

4.1   Number of Shares.  Subject to adjustment as provided in
      Section 4.2 herein, the total number of Shares available
      for grant under the Plan shall be 100,000 Shares.  The
      Shares may be authorized but unissued Shares, reacquired
      Shares or a combination thereof.

4.2   Adjustments in Available Shares and Options.  In the event
      of any merger, reorganization, consolidation,
      recapitalization, separation, liquidation, stock dividend,
      split-up, share combination, or other change in the capital
      structure of Comptek affecting the Shares, such adjustment
      shall be made in the number of Shares which may be granted
      under the Plan, and in the number of and/or price of Shares
      subject to outstanding Options under the Plan, as may be
      determined to be appropriate and equitable by the
      Committee, in its sole discretion, to prevent dilution or
      enlargement of rights under the Plan or any Option;
      provided that the number of Shares subject to any Option
      shall always be a whole number.

                      ARTICLE 5 - STOCK OPTIONS

5.1   Grant of Options.
          Subject to the terms and provisions of the Plan, an
      Option to purchase 10,000 Shares will automatically be
      granted on December 10, 1993, to each then-Eligible
      Director.  Each director who becomes an Eligible Director
      after December 10, 1993, will automatically be granted
      options on 10,000 Shares at the time he becomes a non-
      employee member of the Board of Directors.  Each Eligible
      Director shall automatically receive an additional Option
      to purchase 1,000 Shares, effective at the close of
      business five (5) business days after the 1994 Annual
      Meeting of Shareholders and each Annual Meeting thereafter,
      provided the individual in all respects continues to be an
      Eligible Director.  Further, each Eligible Director or
      director who becomes an Eligible Director, shall
      automatically receive an option to purchase 5,000 Shares as
      of the beginning of the calendar quarter immediately
      following such director first acquiring ownership of at
      least 5,000 Shares.  Provided, however, (i) any Eligible
      Director who already owns at least 5,000 Shares as of July
      25, 1997, shall automatically receive such 5,000 Share
      option-grant as of October 1, 1997, and (ii) each director
      who becomes an Eligible Director after July 25, 1997, and
      then owns at least 5,000 Shares shall automatically receive
      such 5,000 Share option-grant as of the beginning of the
      calendar quarter immediately following such director
      becoming an Eligible Director.  As provided in Section 4.1
      herein, at no time shall more than 100,000 Shares be
      available for grant under the Plan.

5.2   Option Certificate.  Each Option grant shall be evidenced
      by an Option Certificate that shall specify the Option
      Price, the Option duration, the number of Shares to which
      the Option pertains, and such other provisions as the
      Committee shall determine.

5.3   Option Price.  The Option Price for each Share subject to
      the Option shall be equal to one hundred percent (100%) of
      the Fair Market Value of a Share on the date the Option is
      granted.

5.4   Duration of Options.  Each Option shall expire on the tenth
      (10th) anniversary date of its grant.

5.5   Exercise of Options.  Subject to Sections 5.7 and 5.10
      hereof, and all other restrictions and conditions set forth
      in this Plan, Options granted under the Plan shall be
      exercisable one (1) year after the date of grant.

5.6   Payment.  Options shall be exercised by the delivery of a
      written notice of exercise to the Secretary of Comptek,
      setting forth the number of Shares with respect to which
      the Option is to be exercised, accompanied by full payment
      for the Shares.

      The Option Price upon exercise of any Option shall be
      payable to Comptek in full either:  (a) in cash or its
      equivalent, or (b) by tendering previously acquired Shares
      having an aggregate Fair Market Value at the time of
      exercise equal to the total Option Price.

      As soon as practicable after receipt of a written
      notification of exercise and full payment, Comptek shall
      deliver to the Participant, in the name or names designated
      by the Participant, Share certificates in an appropriate
      amount based upon the number of Shares purchased under the
      Option(s).

5.7   Termination of Membership on Comptek's Board of Directors.

      (a) Termination by Death.  If the service on the Board by a
          Participant is terminated by reason of death, all
          outstanding Options granted to that Participant shall
          remain exercisable at any time prior to the expiration
          date, or for one (1) year after the date of death,
          whichever period is shorter, by such person or persons
          as shall have been named as the Participant's
          beneficiary, or by such persons that have acquired the
          Participant's rights under the Option by will or by the
          laws of descent and distribution.

      (b) Termination by Disability.  If the service on the Board
          by a Participant is terminated by reason of Disability,
          all outstanding Options granted to that Participant
          shall remain exercisable at any time prior to their
          expiration date, or for one (1) year after the date of
          such termination, whichever period of shorter.

      (c) Termination of Director's Service for Other Reasons.
          If the service on the Board by a Participant shall
          terminate for any reason other than the reasons set
          forth in subsections (a) and (b) of this Section 5.7,
          all outstanding Options granted to that Participant
          shall remain exercisable for a period ending on the
          expiration date of the Option or for six (6) months
          after such termination, whichever period is shorter.

5.8   Forfeiture of Options.  Unless an Option is otherwise
      exercisable pursuant to Section 5.7 hereof, no Option may
      be exercised unless the Participant is a member of the
      Board at the time of exercise and shall have been
      continuously in office since the grant of the Option.

5.9   Nontransferability of Options.  No Option granted under the
      Plan may be sold, transferred, pledged, assigned, or
      otherwise alienated or hypothecated, except in accordance
      with the Participant's beneficiary designation, by will, or
      by the laws of descent and distribution, or pursuant to the
      requirements of a Qualified Domestic Relations Order.
      Further, all Options granted to a Participant under the
      Plan shall be exercisable during his lifetime only by such
      Participant or his guardian or legal representative.

5.10  Change in Control.  Upon the occurrence of a Change in
      Control, unless otherwise specifically prohibited by the
      terms of applicable law or regulation, any and all Options
      granted hereunder shall become immediately exercisable.


                 ARTICLE 6 - BENEFICIARY DESIGNATION

Each Participant under the Plan may, from time to time, name any
beneficiary or beneficiaries (who may be named contingently or
successively) to whom any benefit under the Plan shall accrue in
case of his death.  Each such designation shall revoke all prior
designations by the same Participant, shall be in a form
prescribed by Comptek, and will be effective only when filed by
the Participant in writing with the Secretary of Comptek during
the Participant's lifetime.  In the absence of any such
designation, benefits remaining at the Participant's death shall
accrue to the Participant's estate.


         ARTICLE 7 - AMENDMENT, MODIFICATION, AND TERMINATION

Amendment, Modification, and Termination.  The Plan may be
amended at any time and from time to time by the Board as the
Board shall deem advisable; provided, however, that no amendment
shall become effective without shareholder approval if such
shareholder approval is required by law, rule or regulation; and
provided further, to the extent required by Rule 16b-3 under
Section 16 of the Exchange Act, in effect from time to time, Plan
provisions relating to the amount, price and timing of Options
shall not be amended more than once every six months, except that
the foregoing shall not preclude any amendment to comport with
changes in the Internal Revenue Code of 1986, the Employee
Retirement Income Security Act of 1974 or the rules thereunder in
effect from time to time.  No amendment of the Plan shall
materially and adversely affect any right of any participant with
respect to any Option theretofore granted without such
Participant's written consent.

                       ARTICLE 8 - WITHHOLDING

8.1   Tax Withholding.  Comptek shall have the power and the
      right as set forth in this Article 9 to deduct or withhold,
      or require a Participant to remit to Comptek, an amount
      sufficient to satisfy any and all Federal, state, and
      local, taxes (including the Participant's FICA obligation)
      required by law to be withheld with respect to any taxable
      event arising out of or as a result of this Plan.

8.2   Share Withholding.  With respect to tax withholding
      required upon the exercise of Options, or upon any other
      taxable event hereunder, a Participant may elect, subject
      to the approval of the Board, in its discretion, to satisfy
      the withholding requirement, in whole or in part, by having
      Comptek withhold a number of Shares, the Fair Market Value
      of which, in itself or when added to a cash payment made by
      the Participant to Comptek, equals the amount of tax
      required to be withheld.  Any such election shall be made
      in conformity with Rule 16b-3e promulgated under the
      Exchange Act, including all requirements as to the timing
      of the election and the exercise thereof.


                        ARTICLE 9 - SUCCESSORS

All obligations of Comptek under the Plan, with respect to
Options granted hereunder, shall be binding on any successor to
Comptek, whether the existence of such successor is the result of
a direct or indirect purchase, merger, consolidation or
otherwise, of all or substantially all of the business and/or
assets of Comptek.


                   ARTICLE 10 - LEGAL CONSTRUCTION

10.1  Gender and Number.  Except where otherwise indicated by the
      context, any masculine term used herein also shall include
      the feminine; the plural shall include the singular and the
      singular shall include the plural.

10.2  Requirements of Law.  The granting of Options and the
      issuance of Shares under the Plan shall be subject to all
      applicable laws, rules and regulations, and to such
      approvals by any governmental agencies or national
      securities exchanges as may be required.

10.3  Securities Law Compliance.  Transactions under this Plan
      are intended to comply with all applicable conditions of
      Rule 16b-3 of the Exchange Act.

10.4  Governing Law.  To the extent not preempted by Federal law
      (or foreign law, in the case of grants to Employees who are
      not United States residents), the Plan, and any agreement
      hereunder, shall be construed in accordance with and
      governed by the laws of the State of New York.

10.5  Severability.  In the event any provision of the Plan or
      any action taken thereunto shall be held illegal or invalid
      for any reason, the illegality or invalidity shall not
      affect the remaining parts of the Plan, and the Plan shall
      be construed and enforced as if the illegal or invalid
      provision had not been included, and the illegal or invalid
      action shall be deemed null and void.

     FOR VALUE RECEIVED, the undersigned, John J. Sciuto,
residing at 6392 Black Walnut Court, East Amherst, New York 14051

following dates: (i) January  31, 2004; (ii) the ninetieth (90th)
day after the day on which Borrower ceases to be employed by

     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

between the Payment Date and the date of repayment of the entire
Aggregate Past Due Balance and a 360-day year.

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

     Each of the following occurrences shall constitute an event
of default (AEvent 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 payment of principal outstanding on this Promissory Note as
provided for in the Loan Agreement, dated as of the date hereof,
(the "1999 Loan Agreement") by and between Comptek and the
Borrower; (b) an Event of Default or failure to pay any amount
under the Promissory Note dated July 9, 1996 by Borrower to
Comptek.

     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.

     Anything in the foregoing to the contrary notwithstanding,
it is understood and agreed that this Note is evidence solely
for, and there shall be payable hereunder only, so much of said
principal sum of and
__________________________________________________  00/100
Dollars ($_________________ ) as shall have been advanced by
Comptek to John J. Sciuto pursuant to the 1999 Loan Agreement.

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

                       CHARLES E. DOWDELL



THIS AGREEMENT, made as of the 18th day of March, 1999, by and
between CHARLES E. DOWDELL, residing at 5121 Donnington Road,
Clarence, NY 14031 (hereinafter "Employee"), and COMPTEK-AMHERST,
INC., a New York corporation which is a wholly-owned subsidiary
of Comptek Research, Inc., having its office and principal place
of business at 30 Wilson Road, Williamsville, New York
(hereinafter called the "Corporation").

                     W I T N E S S E T H :

     WHEREAS,  immediately  prior  to  the  execution   of   this
Agreement, Employee was employed as President of Amherst Systems,
Inc.,  and it is the intention of the parties that he be employed
by the Corporation in such position; and

     WHEREAS, Employee acknowledges that he has and will continue
to  develop  specialized knowledge of, and personal relationships
with,   the  Corporation's  customers  and  their  products   and
operations; and

     WHEREAS, this Agreement is one of several similar agreements
by and between the Corporation and certain key executives; and

     WHEREAS,  it  is the intention of the parties to  have  this
Agreement  and such similar Agreements construed in a  consistent
manner in accordance with the laws of the State of New York; and

     WHEREAS,  the  Corporation wishes to be  reasonably  assured
that  Employee will continue as an employee and desires to retain
his services, realizing that if he were to enter into competition
with the Corporation it would suffer financial loss; and

     WHEREAS,  concurrently with the execution  and  delivery  of
this  Agreement, Comptek Research, Inc. ("Buyer")  is  purchasing
certain  assets  from  Amherst Systems,  Inc.,  ("Amherst"),  the
Corporation and Employee wish to provide for continued employment
of  Employee  with the Corporation upon the terms and  conditions
set forth in this Agreement;

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

     1.     Term  of Employment.  The Corporation hereby  employs
Employee  and Employee agrees to work for the Corporation  for  a
period  of  three (3) years beginning March 18, 1999, and  ending
March  31,  2002,  subject, however, to  earlier  termination  as
provided in paragraphs 4, 5, 11, and 12.

     2.     Duties  and Responsibilities.  Employee  agrees  that
during  the  term  of  this  Agreement  his  principal  area   of
responsibility shall be that of executive level management of the
Corporation.   Employee shall devote his full business  time  and
best efforts, skills, and ability to promote the business of  the
Corporation  and perform for the Corporation such duties  as  are
customarily  performed  by  a management  or  executive  employee
having responsibility in such areas, and such other duties as may
be  assigned to him by the Chairman of the Board of Directors  of
the  Corporation and serve as an officer and/or a director of the
Corporation if duly elected.  Employee shall have such power  and
authority  as  shall  reasonably be required  to  enable  him  to
perform  his  duties hereunder in an efficient  manner;  provided
that  in  the  exercising of such power  and  authority  and  the
performance of such duties, he shall at all times be  subject  to
the  supervision and direction of the Chairman of the Board,  and
the  authority  and  control of the Board of  Directors,  of  the
Corporation.

     3.    Remuneration.

(a)   So long as Employee is employed by the Corporation, he will
be paid a salary at such rate as may be fixed from time to time
by the Board of Directors of the Corporation, but not less than
One Hundred Sixty-seven Thousand Six Hundred Twenty-seven and
20/100 Dollars ($167,627.20) per year (his current "Base
Salary"), payable in approximately equal installments at such
intervals as the Corporation pays the salaries of its executive
employees generally.

     (b)    It  is understood that temporary disability (of  less
than  six  (6) months in duration) will not result in termination
of  Employee's employment, during which period of time Employee's
then Base Salary shall continue in effect.

     (c)    Employee  will be entitled to reimbursement  for  all
reasonable  travel and other business expenses incurred  by  him.
Employee  will  be included in any group life insurance,  medical
insurance, pension, profit-sharing plans or other benefits  which
the  Corporation  may have in force from time  to  time  for  its
executive  personnel, provided, however, group medical  insurance
will  not  be materially less favorable to Employee than  is  the
case  as  of the date of this Agreement.  Such benefits  and  any
resulting  payments thereunder shall be in addition to  his  Base
Salary  and  shall continue in force during any  period  of  Base
Salary continuation.


     4.    Death Benefits.

     (a)    If  Employee should die while still in the employ  of
the  Corporation,  the  Corporation will pay  to  his  designated
beneficiary

           (i) his Base Salary in effect at the time of death for
               the  balance  of  the  month in  which  his  death
               occurs, plus

           (ii)      in each of the first twelve months following
               the  month  in which his death occurs,  an  amount
               equal to one twelfth (1/12) of his Base Salary  in
               effect at the time of death.

     (b)   If the designated beneficiary is not alive at the time
of the making of any of such payments, the payments shall be made
in  equal shares to such of the children of  Employee as shall be
surviving at the time of each of such payments; or, if   Employee
has  no surviving designated beneficiary or children at the  time
of the making of any such payments, then a lump sum payment shall
be  made to Employee's estate in accordance with paragraph 13  of
this Agreement.

     5.      Termination  of  Employment  Due   to   Illness   or
Disability.

     (a)    In the event of the disability or illness of Employee
rendering  him  substantially unable to  render  service  to  the
Corporation of the character contemplated by this Agreement for a
period  in  excess of six (6) months, the Corporation shall  have
the  right to terminate this Agreement upon giving not less  than
thirty (30) days' advance written notice given after such six (6)
month period of its intention to terminate Employee.  If Employee
shall  have  resumed his duties hereunder within such  thirty-day
period  and shall have continuously performed his duties  for  at
least  two  (2)  consecutive months thereafter,  such  notice  of
termination  shall  be  deemed of no force  or  effect  and  this
Agreement shall thereupon continue in full force, as though  such
notice  of  termination  had not been  given.   In  the  event  a
question arises hereunder as to Employee's incapacity to  perform
his  regular  duties, Employee shall be examined by  a  physician
selected  by  the Corporation and  Employee, and such physician's
determination  shall be final and conclusive and binding  on  all
parties for the purposes hereof.

     (b)    Upon  termination of his employment because  of  such
illness  or disability, the Corporation shall pay to Employee  in
each  of the first twelve months following the effective date  of
such  termination,  a monthly termination payment  equal  to  one
twelfth  (1/12) of his Base Salary in effect at the time of  such
termination.

     (c)     In   the  event  of  Employee's  death  after   such
termination on account of such illness or disability, but  before
the  completion of the making of the payments to which he  became
entitled  as provided for above, the Corporation shall make  such
payments  to   Employee's  designated  beneficiary;  or,  if  the
designated beneficiary is not alive at the time of the making  of
any  of such payments, the payments shall be made in equal shares
to  such of the children of Employee as shall be surviving at the
time  of  each of such payments; or, if Employee has no surviving
designated beneficiary or children at the time of the  making  of
any  such payments, then a lump sum payment shall be made to  the
Employee's  estate  in  accordance  with  paragraph  13  of  this
Agreement.

     6.     Non-Competition.  It is understood  and  agreed  that
during the term of his employment by the Corporation, and, in the
event  that he resigns or is discharged, for a period of one  (1)
year   following  the  effective  date  of  termination  of   his
employment by the Corporation, for whatever reason, or the period
of  time  remaining  on  the  Non-Competition  Agreement  between
Employee  and  Buyer, whichever is longer in  duration,  Employee
shall  not engage directly or indirectly in any business  in  the
continental United States which is substantially similar  to  the
business  of the Corporation, either as a proprietor, stockholder
(other  than  as  a holder of less than 5% of any  class  of  the
securities  of  a  corporation registered  under  the  Securities
Exchange Act of 1934, as amended), partner, officer, employee  or
otherwise, unless the Corporation has first consented in  writing
thereto.   In  addition to the foregoing covenants,  it  is  also
understood and agreed that during the greater of (i) one (1) year
following   Employee's  termination  of   employment   with   the
Corporation,  for  whatever reason, or (ii) the  length  of  time
remaining pursuant to any noncompetition agreement by and between
the  Corporation  (or  any  affiliate  of  the  Corporation)  and
Employee in effect, or to be put into effect, as of the  date  of
this   Agreement,  Employee  shall  not  solicit   any   of   the
Corporation's customers with which he dealt while he was employed
by  the  Corporation, either on behalf of himself  or  any  other
person or entity engaged in any business substantially similar to
the business of the Corporation, unless the Corporation has first
consented in writing thereto.

     7.     Trade  Secrets.   In  the course  of  performing  his
duties,  Employee will be engaged in the development, manufacture
and  sale of a variety of computer hardware and software products
based  upon  experimental and inventive work, and  Employee  will
receive,  and  acknowledges  that he has  received,  confidential
information  of  the  Corporation including, without  limitation,
information  not  available  to  competitors  relating   to   the
Corporation's  existing and contemplated products,  manufacturing
procedures,    methods,   machines,   computations,   technology,
formulae,  trade  secrets,  know-how,  research  and  development
programs,  discoveries,  improvements and  ideas  (regardless  of
whether or not patentable), customer information, all of which is
hereinafter referred to as "Trade Secrets."  Employee agrees that
he  will not, either during his employment or subsequent  to  the
termination  of  his employment by the Corporation,  directly  or
indirectly  disclose,  publish or  otherwise  divulge  any  Trade
Secrets to anyone outside the Corporation or use such information
in  any  manner  which  would adversely affect  the  business  or
business  prospects  of  the Corporation, without  prior  written
authorization  from the Corporation to do so.   Without  limiting
the  generality  of  the foregoing, Employee  agrees  that  while
employed  by the Corporation he will not, except with  the  prior
written  consent  of a duly authorized superior  officer  of  the
Corporation,  disclose or otherwise divulge to  any  unauthorized
person,  any  Trade  Secrets and that if,  at  the  time  of  the
termination  of  his  employment by  the  Corporation  he  is  in
possession   of   any   documents  or  other  written   materials
constituting,  containing or reflecting Trade  Secrets,  he  will
return and surrender all such documents and written materials  to
the  Corporation  upon leaving its employ.  The restrictions  and
protection provided for in this paragraph shall be in addition to
any protection afforded to Trade Secrets by law or equity.

     8.     Inventions.   Employee agrees  that  all  inventions,
discoveries and improvements, and all new ideas for manufacturing
and  marketing  products of the Corporation, which  Employee  has
conceived  or  may  conceive while employed by  the  Corporation,
whether during or outside business hours, on the premises of  the
Corporation or elsewhere, alone or in collaboration with  others,
or  which he has acquired or may acquire from others, and whether
or  not  the  same  can be patented or registered  under  patent,
copyright,  or trademark laws, shall be and become the  sole  and
exclusive  property  of  the  Corporation.   Employee  agrees  to
promptly  disclose  and  fully  acquaint  the  President  or  the
Chairman   of  the  Board  of  the  Corporation  with  any   such
inventions,  discoveries, improvements and  ideas  which  he  has
conceived,  made or acquired, and shall, at the  request  of  the
Corporation,  make a written disclosure of the same  and  execute
such applications, assignments, and other written instruments  as
may  reasonably be required to grant to the Corporation sole  and
exclusive  right, title and interest thereto and therein  and  to
enable  the Corporation to obtain and maintain patent, copyright,
and trademark protection therefor.

     9.   Non-Solicitation and Non-Interference.  For a period of
one  (1)  year  following Employee's termination  of  employment,
Employee shall not, directly or indirectly, on his own behalf  of
another  person or entity (i) contact, solicit, offer to hire  or
hire  any person who was, within a period of six months prior  to
such  termination, employed by the Corporation; (ii)  communicate
nor  have  contact  with the Corporation's employees,  customers,
suppliers, other persons with whom the Corporation may then  have
business  relations which communication or contact may  interfere
with   or   otherwise  interrupt  the  Corporation's  operations,
employment or business relationships with such persons, or  (iii)
by any means issue or communicate any private or public statement
which  may  be  critical or disparaging of the  Corporation,  its
products, services, officers, directors or employees.

     10.     Enforcement   of   Covenants.    The   Corporation's
obligation to make any or all of the payments provided for  under
this  Agreement is conditioned upon and shall cease and terminate
in  the  event of  a material breach by Employee of  any  of  the
covenants  contained  herein.  Employee  acknowledges  that  such
payments   are   full   and   adequate   compensation   for   his
non-competition with the Corporation.

     The Corporation, however, shall not cease to perform any  of
its  covenants  made  under  this  Agreement,  including  without
limitation  the  payment  of money, until  any  alleged  material
breach  of this Agreement by Employee has been adjudicated  by  a
court of competent jurisdiction.

     Employee understands and agrees that because of the personal
relationships with the Corporation's customers which he  has  and
will  continue to form during his employment, and because of  the
specialized  knowledge which he will develop of the Corporation's
and   of   its  customers'  products,  services,  or  operations,
potential irreparable damage would result to the Corporation from
his  competing  with  it  or  divulging  its  Trade  Secrets   as
restricted  by  this Agreement.  Accordingly, Employee  expressly
agrees that in addition to any and all remedies available to  it,
the  Corporation shall have the remedies of money damages  and  a
restraining order, or an injunction, and of any other appropriate
equitable  relief, without the necessity of posting any  bond  or
surety,  in  the  event that there is a breach of  any  covenants
contained in this Agreement.

     11.    Termination  of Employment by the  Corporation.   The
Corporation  may,  of  its  own  volition,  terminate  Employee's
employment  at  any  time, other than on account  of  illness  or
disability,  upon  giving  at least  thirty  (30)  days'  advance
written  notice  to  Employee of the date when  such  termination
shall  become  effective.   In  the event  of  such  termination,
Employee during his life shall be entitled to receive, so long as
he  shall  not breach (and shall not have breached)  any  of  the
provisions of this Agreement, or have been terminated for  cause,
monthly  payments for a period of twelve months  next  succeeding
the  effective  date of termination, each payment  equal  to  one
twelfth  (1/12) of his Base Salary in effect at the time of  such
termination.   Employee's  employment  shall  be  deemed  to   be
terminated  for cause where the Corporation determines,  in  good
faith, that there has been continuing neglect by Employee of  his
duties  hereunder, continuing after written notice and  a  thirty
(30)  day  period  in  which to cure, or  willful   and  material
misconduct on his part in connection with the performance of such
duties,  where  Employee  suffers  a  loss  of  his/her  security
clearance  at  the level which is in effect at the date  of  this
Agreement, or  where Employee has been convicted of a felony or a
misdemeanor   involving  moral  turpitude.   If  the  Corporation
terminates  Employee's  employment for cause,  Employee  will  be
entitled  to receive his Base Salary only through the  date  such
termination of employment is effective.

     12.    Termination of Employment by Employee.  Employee may,
of  his  own volition, terminate his employment at any time  upon
giving  at least thirty (30) days' advance written notice to  the
President  or  the  Chairman of the Board  of  Directors  of  the
Corporation  of  the  date  when such  termination  shall  become
effective.   If Employee terminates his employment, Employee will
be entitled to receive his Base Salary only through the date such
termination of employment is effective.

     13.    Designation  of Beneficiary; Lump  Sum  Payments.   A
designated  beneficiary entitled to receive the benefits  payable
following  the  death of Employee under paragraph 4,  or  payable
following  the death of Employee after termination of  employment
under  paragraph 5, shall be named in a written designation filed
with  the Secretary of the Corporation.  Such written designation
may  be  revoked or amended by Employee at any time.  If no  such
written  designation  of  beneficiary shall  be  filed  with  the
Secretary of the Corporation, or if the designated beneficiary is
not  alive at the time of any payment to be made, the same  shall
be  paid  in equal shares to such of the children of Employee  as
shall be surviving at the time of such payment.  If Employee  has
no  surviving designated beneficiary or children at the  time  of
any payment to be made under paragraph 4 or paragraph 5, the same
shall  be paid to Employee's estate in cash.  In determining  the
eligibility  and  status of persons entitled to receive  payments
under  paragraphs 4 and 5 of this Agreement, the Corporation  may
rely  on  its  records and the good faith determinations  of  its
officers.   In  no event shall the Corporation be liable  to  any
person  for any sums paid to any other persons pursuant  to  such
records and determinations.

     14.     Assignments,   etc.   Neither   Employee   nor   any
beneficiary  designated to receive payments under this  Agreement
shall have any power to transfer, assign, anticipate, mortgage or
otherwise  encumber  in  advance  any  of  the  benefits  payable
hereunder, nor shall such benefits be subject to seizure for  the
payment  of  any  debts  or  judgments  or  any  of  them  or  be
transferable  by  operation in law in the  event  of  bankruptcy,
insolvency  or  otherwise.   The  Corporation  may  assign   this
Agreement,  at its sole discretion, to its parent, subsidiary  or
any affiliated entity.

     15.     Participation  in  Other  Plans.   Nothing  in  this
Agreement  shall  affect any right which Employee  may  otherwise
have  to  participate in, or under any other retirement  plan  or
agreement which the Corporation may now or hereafter provide.

     16.    Binding Agreement.  This Agreement shall  be  binding
upon  the  parties hereto, their heirs, executors, administrators
or successors.

     17.    Revocation.  This Agreement may be amended or revoked
at any time only by mutual written agreement of the parties.

     18.   Cumulative Remedies.  Any of the remedies provided for
herein shall be in addition to any remedy available to either  of
the parties at law or equity.

     19.    Savings Clause.  If any part of this Agreement  shall
be  determined  to be unreasonable in duration or in  area,  then
this  Agreement  is intended to and shall extend  only  for  such
period  of  time  and  in  such  area  as  is  determined  to  be
reasonable.

     20.    New  York Law.  This Agreement shall be construed  in
accordance  with  and governed by the laws of the  State  of  New
York.

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

acceleration or otherwise, of such aggregate outstanding

principal amounts be (A) except for any Libor Rate Portion for

Revolving Loans if such a day falls in any Libor Rate Period for

such Libor Rate Portion, the rate per year, expressed as a

percentage, that is the rate in effect such day as the Bank's

Prime Rate or (B) for any Libor Rate Portion for Revolving Loans

if such day falls in any Libor Rate Period for such Libor Rate

Portion, the rate per year, expressed as a percentage, that is

the total of (I) the Applicable Margin and (II) the rate obtained

by dividing (1) the Libor Rate for such Libor Rate Period by (2)

expressed as a decimal, the difference between 100% and the

Libor Rate Portion for Revolving Loans during any Libor Rate

Period for such Libor Rate Portion if before such Libor Rate

Period begins (a) any Governmental Authority asserts that it is

unlawful, or the Bank determines that it is unlawful, for the

Bank to charge interest with respect to such Libor Rate Portion

during such Libor Rate Period at a rate determined by reference

to a Libor Rate, (b) the Bank determines that sufficient United

States dollar deposits 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

clause (i)(B), and shall begin to be charged as provided in such

clause (i)(A), with respect to any Libor Rate Portion for

Revolving Loans during any Libor Rate Period for such Libor Rate

Portion if any Governmental Authority asserts that it is

unlawful, or the Bank determines that it is unlawful, for the

Bank to continue to charge interest with respect to such Libor

Rate Portion during such Libor Rate Period at a rate determined

by reference to a 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 after 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 for Revolving Loans for

any Libor Rate Period for such Libor Rate Portion, and (ii) all

of such interest payable with respect to any Libor Rate Portion

for Revolving Loans for any Libor Rate Period for such Libor Rate

Portion shall become due on the day after the last day in such

Libor Rate Period.

proceeds of the initial private placement of subordinated

debentures referred to in Section 6c of this Agreement.



          g.   Late Charge.   If any of the principal amount of

any Revolving Loan is not repaid, or any interest payable

pursuant to this Agreement in connection with any Revolving Loan

is not paid, within ten days after the 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) 5% thereof or (ii) $50.



          h.   Non-Usage Fee.   For each period (i) beginning on

the date of this Agreement and ending on the last day of the

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 (I) $27,000,000 minus the

total of (1) the daily average during such period of the

aggregate face amounts of all letters of credit issued for the

account of any Related Entity by the Bank and outstanding at any

time during such period and (2) the daily average during such

period of the aggregate amounts of all draws under any letter of

credit issued for the account of any Related Entity by the Bank

for which the Bank had not been reimbursed at any time during

such period and (II) the daily average during such period of the

aggregate outstanding principal amounts of all Revolving Loans

first by (B) the Applicable Margin 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 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.

Borrower shall pay the amount of such deduction or withholding as

required by such Law.  No such repayment or payment shall be

received by the Bank at such office after 2:00 p.m. eastern

United States time on any day shall be deemed to have been

made or requested to be made prior to such Libor Rate Period

Commencement Date to which such Libor Rate Election relates;

provided, however, that (I) such Libor Rate Period may not extend

beyond the Revolving Loan Maturity Date, (II) such Libor Rate

Election may not change any election made pursuant to any prior

Libor Rate Election and (III) such Libor Rate Election need not

be honored by the Bank if (1) such Libor Rate Election is

received by the Bank more than five or less than three Libor Rate

Business Days before such Libor Rate Period Commencement Date,

(2) any Event of Default occurs or exists before or on such Libor

Rate Period Commencement Date or (3) the total of the dollar

amounts specified in clause (iii) of this sentence is not at

least $100,000.  Each Libor Rate Period shall end on the day

before the numerically corresponding day (or, if there is no

numerically corresponding day, the last day) of the calendar

month that is the number of months (one month, two months, three

months or six months) corresponding to the option elected

pursuant to such Libor Rate Election, except that, if such

numerically corresponding day (or such last day) is not a Libor

Rate Business Day, such Libor Rate Period shall end on the day

before the first Libor Rate Business Day following such

numerically corresponding day (or such last day) unless such

first Libor Rate Business Day does not fall in the same calendar

month as such numerically corresponding day (or such last day),

in which case such Libor Rate Period shall end on the day before

the Libor Rate Business Day immediately preceding such

numerically corresponding day (or such last day).  The Bank may

treat as made by the Borrower and rely upon, and the Borrower

shall be bound by, any Libor Rate Election relating to any

Revolving Loan that the Bank believes in good faith to be valid

and to have been made in the name or on behalf of the Borrower by

any officer of the Borrower, and the Bank shall not incur any

liability to the Borrower or any other Person as a direct or

indirect result of honoring such Libor Rate Election.



          k.   Extension of Revolving Loan Maturity Date.   At

least 30 but not more than 90 days before the Revolving Loan

Maturity Date, the Borrower may request that the Revolving Loan

Exhibit B attached to and made a part of this Agreement.  If

prior to the Revolving Loan Maturity Date the Bank executes and

delivers to the Borrower such extension request, the Revolving

Loan Maturity Date shall automatically be extended to the date

specified in such extension request.  If the Bank does not so

execute and deliver such extension request, the Revolving Loan

Maturity Date shall remain the same.

Rate Portion for Term Loan I and (iii) the date and amount of

to make and no error by the Bank in making any annotation on such

attached schedule or any such similar schedule or loan account

shall affect the obligation of the Borrower to repay the

principal amount of Term Loan I, the obligation of the Borrower

to pay interest on the outstanding principal amount of Term

Loan I or any other obligation of the Borrower to the Bank

pursuant to this Agreement.



          c.   Repayment.   The Borrower shall repay the

pursuant to this Agreement in connection with Term Loan I and

remaining unpaid and all other amounts payable by the Borrower to

the Bank pursuant to this Agreement in connection with Term Loan

I and remaining unpaid.  Each such repayment in part shall be

applied to the installments of the principal amount of Term Loan

I in the inverse order of such installments becoming due.

I is made to but not including the date the outstanding principal

subsequent to the last day described in clause (i) of this

sentence be the rate per year, expressed as a percentage, that is

the total of (A) 3% and (B) the rate in effect such subsequent

day as the Bank's Prime Rate; provided, however, that (1) such

interest shall not be charged as provided in clause (i)(B) of

this sentence, and shall be charged as provided in clause (i)(A)

of this sentence, with respect to any Libor Rate Portion for Term

Loan I during any Libor Rate Period for such Libor Rate Portion

if before such Libor Rate Period begins (a) any Governmental

Authority asserts that it is unlawful, or the Bank determines

that it is unlawful, for the Bank to charge interest with respect

to such Libor Rate Portion during such Libor Rate Period at a

rate determined by reference to a Libor Rate, (b) the Bank

determines that sufficient United States dollar deposits are not

available for such Libor Rate Period to the Bank or any

pursuant to such clause (i)(B) is unavailable, (2) such interest

shall cease to be charged as provided in such clause (i)(B), and

that it is unlawful, for the Bank to continue to charge interest

with respect to such Libor Rate Portion during such Libor Rate

Period at a rate determined by reference to a 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 3c or 3d 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

Portion for Term Loan I for any Libor Rate Period for such Libor

Rate Portion, and (ii) all of such interest payable with respect

to any Libor Rate Portion for Term Loan I for any Libor Rate

Period for such Libor Rate Portion shall become due on the day

after the last day in such Libor Rate Period.



          f.   Late Charge.   If any of the principal amount of

Term Loan I is not repaid, or any interest payable pursuant to

this Agreement in connection with Term Loan I is not paid, within

ten days after the 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) 5% thereof or

          g.   General Provisions as to Repayment and Payment.

Borrower to the Bank pursuant to this Agreement in connection

with Term Loan I shall be made in lawful money of the United

States and immediately available funds at the banking office of

the Bank located at One Fountain Plaza, Buffalo, New York, or at

such other office of the Bank as may at any time and from time to

time be specified in any notice given to the Borrower by the

Bank.  Such repayment or payment shall be made without any setoff

or counterclaim and free and clear of and without any deduction

or withholding for any tax, assessment, fee, charge, fine or

penalty imposed by any Governmental Authority; provided, however,

that, if such deduction or withholding is required by any Law,

(i) such repayment or payment shall include such additional

amount as is necessary to result in the net amount of such

repayment or payment after such deduction or withholding not

being less than the amount of such repayment or payment without

such deduction or withholding, (ii) the Borrower shall make such

deduction or withholding and (iii) the Borrower shall pay the

amount of such deduction or withholding as required by such Law.

No such repayment or payment shall be deemed to have been

received by the Bank until received by the Bank at the office of

the Bank determined in accordance with the second preceding

sentence, and any such repayment or payment received by the Bank

at such office after 2:00 p.m. eastern United States time on any

day shall be deemed to have been received by the Bank at the time

such office opens for business on the next business day of the

Bank.  If the time by which any of the principal amount of Term

Loan I is to be repaid is extended by operation of law or

otherwise, the Borrower shall pay interest on the outstanding

portion thereof during such period of extension as provided in

Section 3e of this Agreement.



          h.   Libor Rate Election.   At any time and from time

to time, the Borrower may irrevocably make a Libor Rate Election

relating to Term Loan I that specifies (i) the Libor Rate

Business Day that is to be the Libor Rate Period Commencement

Date for the Libor Rate Period elected pursuant to such Libor

Rate Election, (ii) whether a one-month, two-month, three-month

or six-month option is elected as to the length of such Libor

Rate Period and (iii) expressed as a dollar amount, the portion

of the outstanding principal amount of Term Loan I to which such

Libor Rate Election relates; provided, however, that (I) such

Libor Rate Period may not extend beyond the date the last

installment of the principal amount of Term Loan I is scheduled

to become due, (II) such Libor Rate Election may not change any

election made pursuant to any prior Libor Rate Election and

(III) such Libor Rate Election need not be honored by the Bank if

(1) such Libor Rate Election is received by the Bank more than

five or less than three Libor Rate Business Days before such

Libor Rate Period Commencement Date, (2) any Event of Default

occurs or exists before or on such Libor Rate Period Commencement

Date or (3) the dollar amount specified in clause (iii) of this

sentence is not at least $100,000.  Each Libor Rate Period shall

end on the day before the numerically corresponding day (or, if

there is no numerically corresponding day, the last day) of the

calendar month that is the number of months (one month, two

months, three months or six months) corresponding to the option

elected pursuant to such Libor Rate Election, except that, if

such numerically corresponding day (or such last day) is not a

Libor Rate Business Day, such Libor Rate Period shall end on the

day before the first Libor Rate Business Day following such

numerically corresponding day (or such last day) unless such

first Libor Rate Business Day does not fall in the same calendar

month as such numerically corresponding day (or such last day),

in which case such Libor Rate Period shall end on the day before

the Libor Rate Business Day immediately preceding such

numerically corresponding day (or such last day).  The Bank may

treat as made by the Borrower and rely upon, and the Borrower

shall be bound by, any Libor Rate Election relating to Term

Loan I that the Bank believes in good faith to be valid and to

have been made in the name or on behalf of the Borrower by any

officer of the Borrower, and the Bank shall not incur any

liability to the Borrower or any other Person as a direct or

indirect result of honoring such Libor Rate Election.



          4.   TERM LOAN II.



          a.   Making and Obtaining Term Loan II.   Upon and

subject to each term and condition of this Agreement, on the

Revolving Loan Maturity Date, the Bank shall make Term Loan II to

the Borrower, and the Borrower shall obtain Term Loan II from the

Bank.  The principal amount of Term Loan II shall be equal to the

lesser of (i) the aggregate outstanding principal amounts of all

Revolving Loans or (ii) $27,000,000.



          b.   Term Loan II Note.   The Bank shall set forth on

the schedule attached to and made a part of the Term Loan II Note

referred to in clause (iii) of Section 5d of this Agreement or

any similar schedule or loan account (including, but not limited

to, any similar schedule or loan account maintained in

computerized records) annotations evidencing (i) each Libor Rate

Portion for Term Loan II, (ii) each Libor Rate Period, Libor Rate

Period Commencement Date, Libor Rate and rate of interest for

each Libor Rate Portion for Term Loan II and (iii) the date and

amount of each payment applied to any Libor Rate Portion for Term

Loan II.  Each such annotation shall, in the absence of manifest

error, be conclusive and binding upon the Borrower.  No failure

of the Bank to make and no error by the Bank in making any

annotation on such attached schedule or any such similar schedule

or loan account shall affect the obligation of the Borrower to

repay the principal amount of Term Loan II, the obligation of the

Borrower to pay interest on the outstanding principal amount of

Term Loan II or any other obligation of the Borrower to the Bank

pursuant to this Agreement.



          c.   Repayment.   The Borrower shall repay the

principal amount of Term Loan II to the Bank in 48 installments,

with the first of such installments to become due on the first

day of the first calendar month after the calendar month in which

Term Loan II is made and one of such installments to become due

on the first day of each succeeding calendar month through the

first day of the forty-eighth calendar month after the calendar

month in which Term Loan II is made, when the Borrower shall

repay the outstanding principal amount of Term Loan II to the

Bank and pay to the Bank all interest payable pursuant to this

Agreement in connection with Term Loan II and remaining unpaid

and all other amounts payable by the Borrower to the Bank

pursuant to this Agreement in connection with Term Loan II and

remaining unpaid.  Such installments shall either be equal in

amount or consist of installments equal in amount followed by one

installment as nearly equal in amount to the others as possible.



          d.   Optional Repayment in Advance.   Except during any

Libor Rate Period for any Libor Rate Portion for Term Loan II,

the Borrower shall have the option of repaying the outstanding

principal amount of Term Loan II to the Bank in advance in full

or part at any time and from time to time; provided, however,

that (i) the amount of any such repayment in part shall be an

integral multiple of $10,000 and (ii) upon making any such

repayment in full the Borrower shall pay to the Bank all interest

payable pursuant to this Agreement in connection with Term Loan

II and remaining unpaid and all other amounts payable by the

Borrower to the Bank pursuant to this Agreement in connection

with Term Loan II and remaining unpaid.  Each such repayment in

part shall be applied to the installments of the principal amount

of Term Loan II in the inverse order of such installments

becoming due.



          e.   Interest.   From and including the date Term Loan

II is made to but not including the date the outstanding

principal amount of Term Loan II 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 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 (A) except for any Libor Rate

Portion for Term Loan II if such a day falls in any Libor Rate

Period for such Libor Rate Portion, the rate per year, expressed

as a percentage, that is the rate in effect such day as the

Bank's Prime Rate or (B) for any Libor Rate Portion for Term Loan

II if such day falls in any Libor Rate Period for such Libor Rate

Portion, the rate per year, expressed as a percentage, that is

the total of (I) the Applicable Margin and (II) the rate obtained

by dividing (1) the Libor Rate for such Libor Rate Period by (2)

expressed as a decimal, the difference between 100% and the

maximum percentage of reserve requirement (including, but not

limited to, any emergency, supplemental or other marginal

percentage of reserve requirement) for such day specified by

Regulation D of the Board of Governors of the Federal Reserve

System for the Bank with respect to eurocurrency liabilities and

(ii) on each day subsequent to the last day described in clause

(i) of this sentence be the rate per year, expressed as a

percentage, that is the total of (A) 3% and (B) the rate in

effect such subsequent day as the Bank's Prime Rate; provided,

however, that (1) such interest shall not be charged as provided

in clause (i)(B) of this sentence, and shall be charged as

provided in clause (i)(A) of this sentence, with respect to any

Libor Rate Portion for Term Loan II during any Libor Rate Period

for such Libor Rate Portion if before such Libor Rate Period

begins (a) any Governmental Authority asserts that it is

unlawful, or the Bank determines that it is unlawful, for the

Bank to charge interest with respect to such Libor Rate Portion

during such Libor Rate Period at a rate determined by reference

to a Libor Rate, (b) the Bank determines that sufficient United

States dollar deposits 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

clause (i)(B), and shall begin to be charged as provided in such

clause (i)(A), with respect to any Libor Rate Portion for Term

Loan II during any Libor Rate Period for such Libor Rate Portion

if any Governmental Authority asserts that it is unlawful, or the

Bank determines that it is unlawful, for the Bank to continue to

charge interest with respect to such Libor Rate Portion during

such Libor Rate Period at a rate determined by reference to a

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 4c or 4d 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 after the calendar month in which Term Loan II is

made, except for any of such interest payable with respect to any

Libor Rate Portion for Term Loan II for any Libor Rate Period for

such Libor Rate Portion, and (ii) all of such interest payable

with respect to any Libor Rate Portion for Term Loan II for any

Libor Rate Period for such Libor Rate Portion shall become due on

the day after the last day in such Libor Rate Period for such

Libor Rate Portion.



          f.   Late Charge.   If any of the principal amount of

Term Loan II is not repaid, or any interest payable pursuant to

this Agreement in connection with Term Loan II is not paid,

within ten days after the 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) 5%

thereof or (ii) $50.

States and immediately available funds at the banking office of

the Bank located at One Fountain Plaza, Buffalo, New York, or at

such other office of the Bank as may at any time and from time to

Bank.  Such repayment or payment shall be made without any setoff

or counterclaim and free and clear of and without any deduction

or withholding for any tax, assessment, fee, charge, fine or

penalty imposed by any Governmental Authority; provided, however,

that, if such deduction or withholding is required by any Law,

Bank and reflected in a document filed by the Borrower with the

Securities and Exchange Commission.  No pending or threatened

claim, audit, investigation or action or other legal proceeding

by or before any Governmental Authority or before any arbitrator

renders invalid or questions the validity of any Acquisition

Agreement or Loan Document or any action taken or to be taken

pursuant to any Acquisition Agreement or Loan Document.  No

audit, investigation or action or other legal proceeding referred

respect or omits to state any fact necessary to make any

statement of fact contained therein not incorrect or misleading

in any material respect.  No Related Entity has failed to

Related Entity can foresee) will or might have any Material

Systems to confirm that such Systems are Year 2000 Compliant and

LESSOR:                            LESSEE:

Witnesseth:

                              I

SMPMA  hereby leases to PRB its facilities located at  43865

and  this  lease comprise two physical structures containing
75,510  +/- square feet and adjoining parking lots  and  all

                             II



The  term of this lease is for a period of three years, from
May  1,  1998  to  April  30, 2001.  This  lease  is  hereby
declared  as  subject  to a financing document  executed  in
connection with a commercial loan issued by Nations Bank, NA
to SMPMA in order to finance the costs of the acquisition of
the real and personal property leased hereunder.  This lease
replaces  the  lease  dated March 1, 1997  which  is  hereby
terminated effective as of May 1, 1998.

                             III


PRB  shall pay to SMPMA, at the address specified herein  or
furnished pursuant hereto, during the lease term, a  "triple
net" annual rental of $1,200,609.00 (hereinafter called  net
rent)  in  equal monthly installments of $100,050.75.   Rent
shall be prorated for any partial months during the term  of
the lease.





All  rent  payments are to be made by PRB to  SMPMA  at  the
address  contained herein or provided pursuant  hereto,  and
are due and payable on the first day of each month for which
said rent applies.

                             IV

It  is  the  intention of the parties that the  rent  herein
specified shall be net to SMPMA in each year during the term
of  this lease, that all costs, expenses and obligations  of
every  kind  relating to the leased property including,  but
not  limited to, real estate and personal property taxes and
grounds  maintenance of the access drive and areas  adjacent
to the subject building, and maintenance of the facility and
systems,  except  as provided in Article  XII  below  or  as
otherwise specifically provided in this lease shall be  paid
by  PRB,  and that SMPMA shall be indemnified by PRB against
such cost, expenses and obligations.  The net rent shall  be
paid   to   SMPMA  without  notice  or  demand  and  without
abatement,   deduction  or  setoff   except   as   otherwise
specifically  provided in this lease.  PRB is not  obligated
to make any mortgage or loan payments incurred by SMPMA.

                              V

From  the  date hereof until the termination of this  lease,
PRB shall keep the leased premises and property insured,  at
its  sole  expense,  against claims for personal  injury  or
property  damage under a policy of general public  liability
insurance  with limits of at least $1,000,000/1,000,000  for
bodily  injury  and  $250,000  for  property  damage.   Such
policies  shall name PRB, SMPMA, and Nations Bank,  N.A.  as
the  insureds.   Prior to occupancy, PRB  shall  deliver  to
SMPMA,   and  Nations  Bank  binders  of  properly  endorsed
policies certifying that such insurance is in full force and
effect.

From  the date hereof until the termination hereof PRB shall
keep   the  building  and  the  building  service  equipment
covered,  at its sole expense, by fire and extended coverage
insurance in an amount equal to 100% of the full replacement
cost  of  the  building and the building service  equipment.
Any  policy  providing such coverage shall contain  the  so-
called  special coverage all risk endorsement and  the  full
replacement cost endorsement.

All  insurance  required to be maintained by  PRB  shall  be
effected  by  valid  and  enforceable  policies  issued   by
insurers of recognized responsibility satisfactory to SMPMA.

All policies of insurance shall name PRB, SMPMA, and Nations
Bank, N.A. as the insured as their respective interests  may
appear.   If  SMPMA so requires, the policies  of  insurance
shall  be  payable  to the holder of any  mortgage,  as  the
interest  of such holder may appear, pursuant to a  standard
mortgage  clause.  All such policies shall,  to  the  extent
obtainable, provide that any loss shall be payable to  SMPMA
or  to the holder of any mortgage notwithstanding any act or
negligence of PRB which might otherwise result in forfeiture
of  such insurance.  All such policies shall, to the  extent
obtainable  contain an agreement by the insurers  that  such
policies shall not be canceled without at least thirty days'
prior  written  notice to SMPMA and to  the  holder  of  any
mortgage to whom loss hereunder may be payable.

                             VI

Subject to the terms of Article XII below, PRB shall, at all
times  during  the  term, and at its own expense,  make  all
necessary  repairs and replacements to the  leased  property
and   to   the  pipes,  heating  system,  plumbing   system,

appliances   and   appurtenances  belonging   thereto,   all
equipment  used in connection with the leased property,  and
the  sidewalks, curbs, parking areas and driveway  adjoining
or  appurtenant  to the leased property.  Such  repairs  and
replacements shall be of good quality and class.  On default

replacements  for  the  Tenant's account,  and  the  expense
thereof  shall  constitute and be collectable as  additional
rent.

                             VII

The  Landlord  shall not be liable for injury or  damage  to
persons  or  property occurring within the leased  property,
unless  caused  by  or  resulting from the  affirmative  and
willful  negligence of the Landlord or any of the Landlord's
agents,   servants,  or  employees  in  the   operation   or
maintenance   of  the  leased  property  or   the   building
containing the leased property.

Except  where  caused  by  the  Landlord's  affirmative  and
willful act of negligence, the Landlord shall not be  liable
for  any  failure or water supply, gas, or electric current;
or  for any injury or damage to person or property caused by
gasoline,  oil,  steam, gas, or electricity,  or  hurricane,
tornado, flood, wind, or similar storms or disturbances,  or
water, rain, or snow which may leak or flow from the street,
sewer, gas mains, or any subsurface area or from any part of
the  building  or  buildings; or for any  interference  with
light or air.

                            VIII

If  Tenant  defaults in any condition or  covenant  of  this
Lease  or  in performing the same and fails to correct  such
default within ten (10) days of written notice thereof  from
Landlord,  the  Landlord may at its  option  terminate  this
Lease,  provided if such default, other than  a  default  in
payment  of rent, cannot be rectified within said  ten  (10)
day  notice period, Tenant shall be deemed to have  complied
if  Tenant  shall  have  commenced to correct  such  default
during such notice period and shall diligently complete such
correction until compliance is had.

In  the  event of a default in the payment of  rent  or  any
installment thereof for ten (10) days after the same is due,
Landlord  may  at  its option without  notice  of  any  kind
terminate  this lease or avail itself of the  right  to  re-
enter  and  take  possession of the  premises  by  force  or
otherwise  or  by any process of law or equity,  all  notice
(including notice to quit) being hereby waived by Tenant and
in  the  event  of such a reentry Landlord  may  re-let  the
premises and the rent obtained from such re-letting shall be
deemed  the  reasonable rental value hereof and  the  Tenant
hereunder shall remain liable to Landlord for any deficiency
in  the rent herein reserved for the remainder of the  term.
Additionally, in the event of a default hereunder  which  is
not  cured  within  10  days after  notice  to  Tenant,  the
Landlord may accelerate the due dates of all rental payments
due  from  the  Tenant to the Landlord under this  Lease  by
requiring the payments of all such sums by the Tenant to the
Landlord.   All amounts of rent required to be paid  by  the
Tenant  to the Landlord under the Lease shall be immediately
due  and  payable  on the date specified in  the  Landlord's
notice.

Should  a  receiver or receivers be appointed  or  should  a
Trustee  in  Bankruptcy be appointed for the assets  of  the
Tenant,  or  should  the Tenant make an assignment  for  the
benefit  of  his creditors, then this Lease  should  not  be
construed  as  an  asset  in the  hands  of  such  receiver,
receivers,  trustee or assignee, but the Landlord  shall  be
entitled  to  re-enter and take possession  and  cancel  and
annul this Lease at its option.  Tenant shall be liable  for
any  attorney's  fees incurred by Landlord in  pursuing  its
rights under this lease after a default by Tenant.

                             IX

The  Tenant  shall  not  have  the  privilege  or  right  of
assigning  or  transferring this Lease,  or  subleasing  any
portion or portions of the premises, without first obtaining
the prior written consent of the Landlord.

                              X

Tenant  agrees that if such property is sold or disposed  of
in  any  manner whatsoever, including a sale at foreclosure,
that  Tenant  shall continue to be bound  to  the  successor
owners  under  the same terms and conditions  as  set  forth
above  and  will attorn to and acknowledge the purchaser  as
Landlord under this Lease, unless the holder of the Deed  of
Trust  shall,  at  or prior to the sale or  within  60  days
thereafter,  notify  the Tenant in  writing  to  vacate  and
surrender the leased premises within 90 days from  the  date
of  sale,  then and in the event of such notice, this  Lease
shall terminate and expire at the end of such 90 day period.

                             XI

This  lease  contains  the  entire  agreement  between   the
parties, and any executory agreement hereafter made shall be
ineffective to change, modify, or discharge it in  whole  or
in  part, unless such executory agreement is in writing  and
signed by both parties.
                             XII



Capital expenditures incurred to repair (if the same is
deemed a capital expenditure under applicable Federal income
tax regulations) (the "Regulations") or replace existing
equipment, machinery or structures shall be amortized using
the straight line method over the useful life of the repair
or replacement as determined by the Regulations, with rent
due under this lease to cover only the percentage of the
capital expenditures which is equal to the percentage of the
useful life of the repair or replacement which will occur
during the term of this lease.  Tenant will not incur any
capital expenditures for which Landlord would have any
liability under the terms of this Article XII without the
prior written consent of the Landlord, such consent not to
be unreasonably withheld or delayed.  Notwithstanding the
foregoing terms of this Article XII, Landlord shall not be
obligated to make any contribution for a repair or
replacement required due to the negligence of the Tenant
(including failure to properly service or maintain equipment
or machinery) or which is covered by insurance which Tenant
is obligated to maintain under this lease.

     Section 3. Representations and Warranties by Sublessee.
     The Sublessee makes the following representations and
warranties to the Agency, the Bondholder and the Sublessor:

     (a) The Sublessee is a corporation duly organized, validly

Delaware, is not in violation of any provision of its certificate
of incorporation or by-laws, and is qualified to do business and

necessary, including the State.

     (b) The execution, delivery and performance of this Sublease
Agreement and the consummation of the transactions herein
contemplated have been duly authorized by all requisite corporate
action on the part of the Sublessee and will not violate any
provision of law, any order of any court or agency of government,
or the certificate of incorporation or by-laws of the Sublessee,
or any indenture, agreement or other instrument to which the
Sublessee is a party or by which it or any of its property is
bound, or be in conflict with or result in a breach of or
constitute (with due notice and/or lapse of time) a default under
any such indenture, agreement or other instrument or result in the

                              - 9 -



nature whatsoever other than Permitted Encumbrances (as defined in

     (c) The assistance of the Agency in the financing of a
portion of the costs of the Project and the leasing thereof to

Agreement and as a qualified "project" in accordance with and as
defined under the Act.

     (e) The completion of the Project did not result in the

one or more of such plants or facilities of the Sublessee within
the State.

     (f) This Sublease Agreement constitutes the legal, valid
and binding obligation of the Sublessee enforceable against the
Sublessee in accordance with its terms.



     Section 4. Lease of Facility and Rent.
     The Sublessor hereby leases to the Sublessee and the
Sublessee hereby leases from the Sublessor the Facility for and
during the term herein provided and upon and subject to the terms
and conditions herein set forth. The Sublessee shall at all

                              - 10 -


times during the term of this Sublease Agreement occupy, use and
operate the Facility as a research facility in accordance with
the provisions of the Act as a qualified "project" and for the
general purposes specified in the recitals to this Sublease
Agreement, except that upon the occurrence of damage,
destruction, or condemnation, the Sublessee need not so occupy,
use and operate the Facility for a period not to exceed one year.

     The term of this Sublease Agreement shall commence on the
date of the execution and delivery of this Sublease Agreement and
shall expire on May 31, 2004, unless sooner terminated pursuant to
the terms of this Sublease Agreement. Provided that the Sublessee
is not in default hereunder, the Sublessee shall have the option
of extending the term for two additional periods of three years
each (each such period being a "Renewal Term"). To exercise its
option as to either such Renewal Term, the Sublessee must give
written notice to the Sublessor at least six (6) months prior to
the expiration of the initial term or the Renewal Term, as the
case may be. The rent for each Renewal Term shall be as set forth
in this Section 4. If the Sublessee does not exercise its option
as to any Renewal Term, this Sublease Agreement shall expire at
the end of the initial term or the initial Renewal Term, as the
case may be and the Sublessee's option as to any remaining Renewal
Term shall be void.

     In the event that the Lease Agreement expires or is
terminated prior to the term of this Sublease Agreement or any of

                              - 11 -


the Renewal Terms, as the case may be, and the Sublessor acquires
fee title to the Facility, the Sublessee and the Sublessor shall
be deemed to have entered into a new lease agreement for the
balance of the term hereof on the same terms and conditions set
forth herein, modified, however, to take into account the
termination of the Lease Agreement. The Sublessor and the
Sublessee agree to execute and deliver a new lease agreement
reflecting such new lease.

     During the initial term of this Sublease Agreement or any
Renewal Term, as the case may be, the Sublessee agrees to make
rental payments to the Sublessor, or its designee, as set forth
below. Such payments shall be made in immediately available
funds on the first day of each month.

                              - 12 -


charge of two percent (2%) of such installment and interest at a
rate of 12% per year from the due date to the date paid.



     Section 5. Grant of Security Interest; Assignment of
Sublease Agreement.
     In order to secure the payment of sublease rentals and all
the obligations of the Sublessee hereunder, the Sublessee hereby
grants a security interest to the Sublessor in all of the
Sublessee's right, title, if any, and interest in and to the
fixtures constituting part of the Facility Realty and the Facility
Equipment and the proceeds thereof.
     The Sublessee acknowledges, agrees and consents to (i) the
assignment by the Sublessor pursuant to the Lease Agreement of all
of its right, title and interest in and to this Sublease Agreement
to the Agency and the subsequent assignment of substantially all
of the Agency's right, title and interest in this Sublease
Agreement to the Bondholder pursuant to the Indenture; and (ii)
the assignment by Sublessor to Bondholder pursuant to the
collateral lease assignment.



     Section 6. Dissolution or Merger of Sublessee; Restrictions
on Sublessee.
    The  Sublessee covenants and agrees that at all times during
the term of this Sublease Agreement, it will (i) maintain its

dissolve or otherwise dispose of all or substantially all of its
property, business or assets remaining after the execution and
delivery of this Sublease Agreement, and (iv) not consolidate with

corporations to consolidate with or merge into it. The Sublessee
may, however, without violating the foregoing, consolidate with or
merge into another corporation, or permit one or more corporations
to consolidate with or merge into it, or sell or otherwise
transfer all or substantially all of its property, business or
assets to another such corporation (and thereafter liquidate,
wind-up or dissolve or not, as the Sublessee may elect) if (i) the
Sublessee is the surviving, resulting or transferee corporation,
as the case may be, or (ii) in the event that the Sublessee is not
the surviving, resulting or transferee corporation, as the case
may be, such corporation (A) is a solvent corporation subject to
service of process in the State and either organized under the
laws of the State, or organized under the laws of any other state
of the United States and duly qualified to do business as a
foreign corporation in the State, (B) assumes in writing all of
the obligations of the Sublessee contained in this Sublease
Agreement and all other Security

Documents (as defined in the Indenture) to which the Sublessee
shall be a party and in the opinion of counsel, who is acceptable
to the Bondholder, (x) such corporation shall be bound by all of
the terms applicable to the Sublessee of this Sublease Agreement
and all other Security Documents to which the predecessor
Sublessee corporation shall have been a party, and (y) such action
does not legally impair the security for the Bondholder afforded
by the Security Documents, and (C) has a net worth (as determined
in accordance with generally accepted accounting principles and
certified by an independent public accountant) after the merger,
consolidation, sale or transfer at lease equal to that of the
Sublessee immediately prior to such merger, consolidation, sale or
transfer.



     Section 7. Financial Statements and No-Default
Certificates.
     (a) The Sublessee agrees to furnish to the Agency and the
Bondholder as soon as available and in any event within ninety
(90) days after the end of each of its Fiscal Years, financial
statements of the Sublessee audited by an independent certified
public accountant.
     (b) The Sublessee shall deliver to the Agency and the
Bondholder with each delivery required by Section 7 (a) hereof, a
certificate of an Authorized Representative of the Sublessee as to
whether or not, as of the close of such preceding Fiscal Year

                              - 15 -


of the Sublessee, and at all times during such Fiscal Year, the
Sublessee was in compliance with all the provisions which relate
to the Sublessee in this Sublease Agreement and in any other
Security Document to which it shall be a party, and if such
Authorized Representative shall have obtained knowledge of any
default in such compliance or notice of such default, he shall
disclose in such certificate such default or defaults or notice
thereof and the nature thereof, whether or not the same shall
constitute an Event of Default hereunder, and any action proposed
to be taken by the Sublessee with respect thereto. In addition,
upon twenty (20) days prior request by the Agency or the
Bondholder, the Sublessee will execute, acknowledge and deliver to
the Agency and the Bondholder a certificate of an Authorized
Representative of the Sublessee either stating that to his
knowledge no default or breach exists hereunder or specifying each
such default or breach of which he has knowledge.



     Section 8. Liability .
     The Sublessee shall defend, indemnify and hold harmless the
Sublessor, the Bondholder and the Agency, and their respective

members, agents and employees from and against all causes of
action, claims, damages, losses and expenses, including bodily
injury or death, or damage to or destruction of property, arising
from or out of the Sublessee's use or occupancy of this Premises
or arising from any negligent act or omission of the Sublessee or

relieve the Sublessee from liability for payment of rent or other
sums due hereunder, or from being bound by any of the terms,
conditions, covenants and agreement of this Sublease Agreement.

Bondholder consent to any proposed assignment, subletting,
encumbrance, or granting of a right of use or occupancy, such

further assignment, subletting, encumbrance or granting of a
right of use or occupancy.

reasonably require, certifying that this Sublease Agreement is
unmodified and in full force and effect (or if there have been
modifications that the same is in full force and effect as
modified and stating the modifications), the dates to which the
rent and other charges have been paid, whether or not to the best
of the executing party's knowledge the other par ty is in default
hereunder, and if so, specifying the nature of the default, and
such other matters as may be required by the Sublessor, the
Sublessee, the Agency or the Bondholder.

                              - 21 -


to enforce performance and observance of this Sublease Agreement

     (a) In the event that at any time during the term of this
Sublease Agreement the whole or part of the Facility shall be
damaged or destroyed, or taken or condemned by a competent
authority for any public use or purpose, or by agreement between
the Agency and those authorized to exercise such right, or if the
temporary use of the Facility shall be so taken by condemnation or
agreement (a "Loss Event"):
          (i) The Agency shall have no obligation to rebuild,
replace, repair or restore the Facility,
          (ii) The Sublessee shall give written notice within ten
(10) days of the occurrence of a Loss Event to the Agency and the
Sublessor and the Bondholder, generally describing the nature and

Renewal Fund and the Sublessee shall either:
          (i) At its own cost and expense (except to the extent
paid from the Net Proceeds deposited in the Renewal Fund as
provided below and in the Indenture), promptly and diligently
rebuild, replace, repair or restore the Facility to substantially

                              - 22 -



its condition immediately prior to the Loss Event, or to a
condition of at least equivalent value, operating efficiency and
function, regardless of whether or not the Net Proceeds derived
from the Loss Event shall be sufficient to pay the cost thereof,
and the Sublessee shall not by reason of payment of any such
excess costs be entitled to any reimbursement from the Agency,
the Sublessor or the Bondholder, nor shall the rent or other

obligations under this Sublease shall cease as of the later of
the dates the Sublessor is so notified or the date the Sublessor
quits the Facility.
     Not later than ninety (90) days after the occurrence of a
Loss Event, the Sublessee shall advise the Agency and the
Bondholder in writing of the action to be taken by the Sublessee
under this Section 5.1(b), a failure to so timely notify being
deemed an election in favor of subdivision (i) above.
     If the Sublessee shall elect to or shall otherwise be
required to rebuild, replace, repair or restore the Facility as
set forth in subdivision (i) above, the Bondholder shall disburse

                              - 23 -


the Net Proceeds from the Renewal Fund in the manner set forth in
the Indenture to pay or reimburse the Sublessee, at the election
of the Sublessee, either as such work progresses or upon the
completion thereof, provided, however, the amounts so disbursed
by the Bondholder to the Sublessee shall not exceed the actual
cost of such work.
     (c) All such rebuilding, replacements, repairs or
restorations shall:
          (i) Automatically be deemed a part of the Facility and
owned by the Agency and be subject to this Sublease Agreement and
the lien and security interest of the Indenture,
          (ii) Be in accordance with plans and specifications and
cost estimates approved in writing by the Bondholder (which

or adjustment of any claim or demand on account of any Loss
Event, and the settlement, compromising, arbitration or
adjustment of any such claim or demand shall be subject:

arbitrations or adjustments of less than $250,000, to the
approval of the Sublessee (such approval not to be unreasonably
withheld), and
          (ii) In the case of all such settlements, compromises,
arbitrations or adjustments of $250,000 or more, to the approval
of the Sublessor and of the Sublessee and the Bondholder (such
approvals not to be unreasonably withheld).
     (g) The Sublessee (either on behalf of itself or any further
Sublessees) shall be entitled to any insurance proceeds or
condemnation award, compensation or damages attributable to
improvements, machinery, equipment or other property installed on
or about the Facility Realty but which, at the time of such damage
or taking, is not part of the Facility and is owned by the
Sublessee or any further Sublessees.
