          SUBJECT TO COMPLETION, DATED APRIL ___, 1999

                    COMPTEK RESEARCH, INC.
                           $15,000,000
      8 1/2% CONVERTIBLE SUBORDINATED DEBENTURES DUE 2004
                               and
1,578,947 SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THE
                           DEBENTURES

By this prospectus, holders of Comptek Research, Inc.  8 1/2%
Convertible Subordinated Debentures due 2004 are offering to sell
an aggregate principal amount of $15,000,000 of the debentures
and/or up to 1,578,947 shares of our common stock in to which the
debentures are convertible.  The debentures were issued by
Comptek at 100% of the principal amount in a private placement in
March 1999.

Interest on the principal amount of the debentures is payable in
arrears at the annual rate of 8 1/2% on October 1 and April 1 of
each year, beginning October 1, 1999.  The holders of the
debentures may convert any principal amount of a debentures, in
multiples of  $1,000, into common stock at a conversion price of
$9.50 per share, subject to adjustment in certain events.  The
debentures, which are unsecured and rank below our existing and
future senior indebtedness, will mature on April 1, 2004, unless
earlier converted or redeemed.

On April 12, 1999, the closing price of our common stock on the
American Stock Exchange (symbol "CTK") was $8.125  per share.

Although our common stock is traded on the American Stock
Exchange, we do not intend to apply for listing of the debentures
on any securities exchange or for quotation through any automated
quotation system.

We will not receive any proceeds from the sale of the debentures
and the common stock into which the debentures are convertible by
the selling holders.  We will pay all expenses (other than
selling commissions and fees and stock transfer taxes) of the
registration and sale of the debentures and the common stock.
The selling holders may offer the debentures or the shares of
common stock through brokers, dealers or agents or directly to
purchasers.  These transactions may be effected at market prices
prevailing at the time of sale or at privately negotiated prices.

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 12 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.

current filings with the SEC.  This summary is not complete and

before investing in the debentures or common stock.

The Company

We develop and integrate 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
     specializes 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 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.

Comptek's executive offices are located at 2732 Transit Road,
Buffalo, New York 14224-2423.  Our telephone number is (716) 677-
4070.

We maintain a Web site at http://www.comptek.com .  Information

                          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.

DEPENDENCE ON FUTURE MILITARY SPENDING - SUBSTANTIALLY ALL OF OUR
SALES ARE DERIVED FROM MILITARY REQUIREMENTS.

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 have a material
adverse impact on our business, financial condition or results of
operations.

DEPENDENCE ON U.S. GOVERNMENT CONTRACTS; RISKS INHERENT IN U.S.
GOVERNMENT CONTRACTS  - AS A U.S. GOVERNMENT CONTRACTOR WE ARE
SUBJECT TO SPECIALIZED RULES AND REGULATIONS.

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 ("DoD").
As a contractor and subcontractor to the U.S. Government, we are
is 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.

FIXED-PRICE CONTRACTS - OUR PERCENTAGE OF FIXED-PRICE CONTRACTS,
WHICH ARE A HIGHER RISK, IS INCREASING.

For the fiscal year ended March 31, 1998, 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 be materially adversely affected.  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.  For the nine months ended December 25, 1998,
as adjusted to give effect to the business operations acquired
from Amherst Systems, Inc. 37.6% of the our sales would have been
fixed-price.

ABILITY TO ASSIMILATE ACQUISITIONS AND ACQUISITION STRATEGY  -
THE INTEGRATION OF RECENT ACQUISITIONS AND THE MAKING OF FUTURE
ACQUISITIONS COULD ADVERSELY IMPACT OUR CURRENT OPERATIONS.

Our acquisitions of Advanced Systems Development in March 1996,
of PRB Associates in May 1998, and of the business operations of
Amherst Systems, Inc. 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, in the near-term or long-term future, 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 certain
financial risks.  Future acquisitions by us may result in
dilutive issuances of equity securities, the incurrence of
additional debt, reduction of existing cash balances,
amortization expenses related to goodwill and other intangible
assets and other charges to operations that may materially
adversely impact our business, financial condition or results of
operations.

SUBSTANTIAL DEBT; NEED FOR ADDITIONAL FINANCING - 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.

At December 25, 1998, our pro forma bank debt was $33.6 million
and our total pro forma funded debt was $55.6 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.

INTERNATIONAL SALES - OUR ABILITY TO SELL PRODUCTS AND SERVICES
INTERNATIONALLY ARE SUBJECT TO U.S. GOVERNMENT EXPORT CONTROLS.
ALSO, GREATER RISKS ARE INHERENT IN DOING BUSINESS ON AN
INTERNATIONAL LEVEL.

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.
Direct sales to foreign governments and international customers
were 13.4% of total sales in fiscal 1998.  In addition to the
uncertainty as to our ability to maintain and expand an
international presence, there are certain risks inherent in doing
business on an international level, including:

     -    unexpected changes in regulatory requirements;
       
     -    problems and delays in collecting accounts receivable;
       
     -    tariffs and other trade barriers;
       
     -    difficulties in staffing and managing foreign operations;
          and
       
     -    longer payment cycles and political instability.
       
Furthermore, effective patent, copyright, and trade secret
protection may be limited or unavailable under the laws of
certain foreign jurisdictions.  There can be no assurance that
one or more of such factors will not have a material adverse
impact on our business, financial condition or results of
operations.

COMPETITIVE ENVIRONMENT  - IN ADDITION TO COMPETING AGAINST LARGE
DEFENSE CONTRACTORS, SOME SMALL COMPETITORS RECEIVE CERTAIN
PREFERENCE IN BIDDING FOR WHICH WE DO NOT QUALIFY.

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.  For the fiscal year ended March
31, 1998, none of  our sales was attributable to contracts which
were awarded as a small business set-aside.  However,
approximately 10.0% of Amherst Systems, Inc. sales for its fiscal
year ended April 30, 1998 were small business set-aside contracts
or small business innovative research grants.

SUBORDINATION - OUR INDEBTEDNESS WHICH IS SENIOR IN RIGHT OF
PAYMENT TO THE DEBENTURES IS SUBSTANTIAL.

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 December 25,
1998 our pro forma aggregated senior indebtedness would have been
approximately $34.6 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.  By
reason of the subordination of the debentures, 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 of Comptek or an event of
default with respect to such indebtedness permitting the
acceleration thereof, our assets will be available to pay the
amounts due on the debentures only after all senior indebtedness
has been paid in full.

YEAR 2000 ISSUE

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 DoD and its departments
and agencies are our largest customer group, representing 87% of
our  fiscal 1998 net sales.  A failure by the DoD 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.

NEED FOR ADDITIONAL TECHNICAL PERSONNEL

The defense electronics industry, similar to the commercial
electronics and software industries, is experiencing difficulties
in recruiting and retaining technical personnel.  Although this
has not had a material adverse impact on us, there can be no
assurances that we will continue to be able to attract and retain
highly-skilled technical and professional employees.

ABSENCE OF PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

Prior to the filing of the registration statement, there has been
no public market for the debentures and, it is unlikely that an
active or liquid trading market will develop or be sustained. The
market price of the common stock into which the debentures are
convertible could be subject to significant fluctuations in
response to various factors and events, including the liquidity
of the market for the common stock and variations in our
operating results.  In addition, the stock market in recent years
has experienced broad price and volume fluctuations that often
have been unrelated to the operating performance of particular
companies.  These market fluctuations also may adversely affect
the market price of the common stock.

                         USE OF PROCEEDS

Comptek will not receive any proceeds from the sale by any
selling security holder of the debentures or the underlying
common stock.
                                
               RATIO OF EARNINGS TO FIXED CHARGES

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

</TABLE>

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.
                                
                       RECENT DEVELOPMENTS

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 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 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 ("EW") 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.
Contract backlog as of December 25, 1998 was $61.7 million, of
which $36.8 million was funded.

The following table set forth our short-term debt and
consolidated capitalization as of the dates indicated including:

     - The pro forma capitalization of Comptek after giving effect
       to the acquisition of the business operations and related assets
       and liabilities of Amherst Systems; and
       
     - Adjustments to reflect the sales of $15 million of 8 1/2%
       subordinated convertible debentures.

(1)  The terms of the acquisition of the business operations of
  Amherst Systems required us to pay $20.0 million in cash at
  closing.  For the purpose of this pro forma presentation, the
  amount payable at closing has been presented as a liability in
  the acquisition adjustments as a means to isolate the impacts of
  the acquisition from those of the offering of the debentures.

  of our common stock under Comptek's equity incentive plans, (ii)
  outstanding options to purchase 103,000 shares under our stock
  option plan for the non-employee directors; including 3,000
  options which were granted contingent upon approval by
  shareholders at the 1999 Annual Meeting of an increase in plan
  reserves, and (iii) 1,500,000 additional shares of common stock
  reserved for issuance upon conversion of the debentures. A total
  of 328,459 options were exercisable under these plans as of
  December 25, 1998 with exercises prices ranging from $3.25 to
  $17.63.

</TABLE>

                    DESCRIPTION OF DEBENTURES

The 8 1/2% convertible subordinated debentures  were issued under
an indenture, dated as of March 24, 1999, signed by 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 following is a summary of certain provisions of the
debentures and the indenture (forms of each are included as
exhibits to the registration statement) does not purport to be
complete and is qualified in its entirety by reference to the
detailed provisions of the debenture and the indenture, including
the definitions of certain terms therein to which reference is
hereby made, for a complete statement of such provisions.
Wherever particular provisions or sections of the indenture or
terms defined therein are referred to herein, such provisions or
definitions are incorporated herein by reference.

General

The debentures are unsecured general obligations of Comptek,
subject to the rights of holders of senior indebtedness of
Comptek, and convertible into 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.

Form of Debentures

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 not contain any provision requiring us to repurchase the
debentures at the option of the holders thereof 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 credit quality, whether
resulting from any such transaction or from any other cause.  The
registered holder of a debenture may be treated as its owner for
all purposes.

Conversion Rights

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 called for redemption is
converted between a record date for the payment of interest and
the next succeeding interest payment date, such debenture must be
accompanied by funds equal to the interest payable to the
registered holder on such interest payment date on the principal
amount so 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, as set forth in
the indenture, in certain events, including:

     -    the payment of dividends or distributions on Comptek's
          common stock in shares of capital stock;
     
     -    subdivisions or combinations of the common stock into a
          greater or smaller number of shares of common stock;
     
     -    reclassification of the shares of common stock resulting in
          an issuance of any shares of our capital stock;
     
     -    distribution of rights or warrants to all holders of 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.
No adjustment in the conversion price need be made unless such
adjustment would require a change of 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 if Comptek reports
income before extraordinary item and accounting change diluted
earnings per share of less than $0.80 for its fiscal year ending
March 31, 2000.  In such case, the conversion price will be reset
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).  Such reset conversion price 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 or subdivide or combine the common stock or issue by
reclassification of our common stock any shares of our capital
stock or merges with, or transfers or leases substantially all of
its assets to, another corporation or trust, the holders of the
debentures then outstanding will be entitled thereafter to
convert such debentures into the kind and amount of shares of
capital stock, other securities, cash or other assets which they
would have owned immediately after such event had such debentures
been converted 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.

Penalty For Late Delivery of Conversion Shares

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
such third business day being the "Delivery Date."  The penalty
payment will apply to the period beginning on the business day
after the Delivery Date and ending on the day we deliver such
shares of common stock to the holder and will accrue at a rate of
0.50% of the principal amount of the debentures subject to such
conversion notice.

Subordination of Debentures

The indebtedness evidenced by the debentures will be subordinated
and junior in right of payment to the extent set forth in the
indenture to the prior payment in full of amounts then due on all
senior indebtedness. No payment shall be made by us on account of
principal of (or premium if any) or interest on the debentures or
on account of the purchase or other acquisition of debentures, if
there shall have occurred and be continuing a default with
respect to any senior indebtedness permitting the holders to
accelerate the maturity thereof, and such default shall be the
subject of a judicial proceeding, or we shall have received
notice of such default from certain authorized persons, unless
and until such default or event of default shall have been cured
or waived or shall have ceased to exist.  By reason of these
provisions, in the event of default on any senior indebtedness,
whether now outstanding or hereafter issued, and so long as such
default is continuing, payments of principal of (and premium, if
any) and interest on the debentures may not be permitted to be
made until such senior indebtedness is paid in full, or the event
of default on such Senior Indebtedness is cured or waived.

Upon any acceleration of the principal of the debentures or any
distribution of assets of Comptek 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 assets so distributed in respect of the debentures.
By reason of this provision, in the event of insolvency, holders
of the debentures may recover less, ratably, than holders of
senior indebtedness.

"Senior indebtedness" is defined to mean 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, our 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.

Optional Redemption

The debentures will be subject to redemption, as a whole or in
part, at any time or from time to time commencing on or after
March 1, 2002 at our option  on at least 30 days' and not more
than 60 days' prior notice by mail.  The redemption prices
(expressed 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%

Certain Rights to Require Repurchase of Debentures by the
Company

In the event of any Change in Control (as described below) of
Comptek occurring after the date of issuance of the debentures
and on or prior to maturity, each holder of debentures will have
the right, at such holder's option, to require us to repurchase
all or any part of such holder's debentures on the date (the
"Repurchase Date") that is 75 days after the date we give notice
of the Change in Control at a price (the "Repurchase Price")
equal to 101.0% of the principal amount thereof, together with
accrued and unpaid interest to the Repurchase Date.  On or prior
to the Repurchase Date, we are 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 Repurchase Date.  Neither our Board of Directors nor the
trustee, acting alone or together, can modify or waive this
required repurchase of the debentures.

Our failure to repurchase the debentures when required under the
preceding paragraph will 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, Comptek is obligated to mail to all holders a notice of
the event constituting and the date of such Change in Control,
the Repurchase Date, 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 Repurchase
Date, written notice to Comptek (or an agent designated by us for
such purpose) and to the trustee of the holder's exercise of such
right, together with the certificates evidencing the debentures
with respect to which the right is being duly exercised, duly
endorsed for transfer.

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 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 such 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 of which 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 and, thus, the removal of
incumbent management.  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 by means of a merger, tender offer, solicitation, or
otherwise, 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 offerings.

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.

Modification of the Indenture

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;
          
     (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.
          
Events of Default, Notice and Waiver

The following is a summary of certain provisions of the indenture
relating to "Events of Default", notice and waiver.

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 Comptek.

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.

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

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
Comptek to consolidate with or merge into or transfer or lease
substantially all of its assets to another corporation or trust
which assumes the obligations of Comptek under the indenture and
debentures or for any reorganization within the meaning of
Section 368(a)(1)(B) of the Internal Revenue Code of 1986, as
amended (the "Code"); nor is any such 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.

Consolidation, Merger, Sale or Conveyance

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.

Marketability

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.

Governing Law

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

Registration Rights Agreement

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 Conversion Shares have
been sold thereby or 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 by the Purchasers. The
Registration Rights Agreement entitles us to suspend temporarily
the right of holders of Registrable Securities to make
dispositions of Registrable Securities pursuant to the
registration statement if any event shall occur as a result of
which our Board of Directors shall determine that it is
necessary, based on the opinion of counsel for Comptek or for the
holders of a majority of the Registrable Securities, to amend or
supplement this prospectus relating to the registration statement
in order to make this prospectus not misleading in the light of
the circumstances existing at the time it is delivered to a
purchaser, prepare a supplement or post-effective amendment to
the registration statement or the related prospectus or any
document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the
purchasers of the Registrable Securities, the prospectus will not
contain an untrue statement of a material fact or omit to state
any material fact necessary to make the statements therein not
misleading.  Notwithstanding the foregoing, we shall not under
any circumstances be entitled to exercise its right to defer
sales of Registrable Securities except as follows:  we may defer
sales of Registrable Securities for a period not to exceed an
aggregate of 60 days in any 365 day period, and the period in
which sales of Registrable Securities are suspended shall not
exceed 15 days unless we shall deliver to such holders of
Registrable Securities one or more subsequent notices to the
effect set forth above, each of which shall have the effect of
extending the period during which sales of Registrable Securities
are deferred by up to an additional 15 days, or such shorter
period of time as is specified in such subsequent notice.
                                
                         SELLING HOLDERS

The debentures were originally issued by Comptek 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 holders (which term includes their transferees, pledgees
or donees or their successors) 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 following table sets forth information, as of April 22, 1999,
with respect to the selling holders and the respective principal
amounts of debentures beneficially owned by each selling holder
that may be offered pursuant to this prospectus.  The information
is based on information provided by or on behalf of the selling
holders.  The selling holders may offer all, some or none of the
debentures or common stock into which the debentures are
convertible.  Because the selling 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 holders upon termination of any such
sales.  In addition, the selling 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.

</TABLE>

None of the selling holders has had any material relationship
with Comptek or its affiliates within the past three years.  The
selling 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 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 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 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.

                      PLAN OF DISTRIBUTION

The selling holders and their successors (which term includes
their transferees, pledgees or donnes or 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 holders or the purchasers (which 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, (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 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 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 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.  Comptek will not
receive any of the proceeds from this offering.

Comptek's 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.

The selling 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
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 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 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.

To the extent required, the specific debentures or common stock
to be sold, the names of the selling 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 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 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.

                          LEGAL MATTERS

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
Comptek.  As of April 22, 1999, Mr. Head owns less than one
percent of the outstanding shares of the Comptek.

Item 15.  Indemnification of Directors and Officers.

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
     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.

Item 17.  Undertakings

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;

               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.  Filings Incorporating Subsequent Exchange Act Documents by
     Reference.

     The undersigned registrant hereby undertakes that, for
     purposes of determining any liability under the Securities
     Act of 1933, each filing of the registrant's annual report
     pursuant to section 13(a) or section 15(d) of the Securities
     Exchange Act of 1934 that is incorporated by reference in
     this registration statement 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.

III. 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.


                           SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe
that it meets all the requirements for filing on Form S-3 and has
duly caused this registration statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in Buffalo,
New York on April 22, 1999.

                         THE SECURITIES
                                
SECTION 2.1.  Form; Dating; Incorporation of Form in Indenture.
          The aggregate principal amount of Securities which may
be authenticated and delivered under this Indenture is limited to
$20,000,000, except for Securities authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu
of, other Securities pursuant to Sections 2.3, 2.5, 2.6, 2.8, 3.6
or 9.5.

          The Securities shall be known and designated as the 8
1/2% Convertible Subordinated Debentures due 2004 of the Company.
Their fixed maturity shall be April 1, 2004, and they shall bear
interest at the rate per annum of 8 1/2%, from and including the
date of issuance thereof until maturity or earlier redemption,
payable semiannually on April 1 and October 1 commencing October
1, 1999 (each an "Interest Payment Date"), until the principal
thereof is paid or made available for payment.  Subject to
Section 2.10, such interest shall be paid to the Holder in whose
name each Security was registered at the close of business on the
Regular Record Date next preceding each Interest Payment Date.

          The Company may at any time during the 30-day period
following the Initial Issue Date, without the consent of the
Holders of the Securities then outstanding, create and issue
additional Securities, in an aggregate principal amount equal to
an amount that when added to the aggregate principal amount of
Securities previously authenticated and delivered hereunder will
not exceed $20,000,000.  Such Securities shall have the same
terms, conditions, rights and benefits as the Securities issued
on the Initial Issue Date and references in this Indenture to
"Securities" shall be construed accordingly.  Purchasers of
Securities issued after the Initial Issue Date will be required
to pay the Company accrued interest from the Initial Issue Date
until the date of issuance of such Securities.

          The Securities shall be redeemable as provided in
Article 3.

          The Securities shall be subordinated in right of
payment to Senior Indebtedness, to the extent provided in
Article 11.

          The Securities shall be convertible as provided in
Article 10.

          The Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A
which is incorporated in and made part of this Indenture.  The
Securities may have notations, legends or endorsements required
by law, stock exchange rules, agreements to which the Company is
subject, or usage.  The Company shall approve the form of the
Securities and any notation, legend or endorsement on them.  Each
Security shall be dated the date of its authentication.

          The terms and provisions contained in the Securities
shall constitute, and are hereby expressly made, a part of this
Indenture and to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound
thereby.

          All Securities will be issued in fully registered form
in denominations of U.S. $1,000 and integral multiples thereof
(the "Registered Securities"), which Securities shall be in
substantially the form of Exhibit A hereto.  The Registered
Securities which are Restricted Securities are hereinafter
collectively referred to as "Registered Accredited Investor
Securities."

SECTION 2.2.  Execution and Authentication.
          Two Officers shall sign the Securities for the Company
by manual or facsimile signature.

          If one or both of the Officers whose signatures are on
a Security no longer holds that office at the time the Trustee
authenticates the Security, the Security shall nevertheless be
valid.

          A Security shall not be valid until the Trustee
manually signs the certificate of authentication on the Security.
Such signature shall be conclusive evidence that the Security has
been authenticated under this Indenture.  Notwithstanding the
foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and
the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 2.9, for all purposes of this
Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

          The Trustee shall authenticate Securities for original
issue in the aggregate principal amount of up to $20,000,000 upon
the execution of the Indenture and a written order or orders of
the Company signed by two Officers or by an Officer and an
Assistant Treasurer of the Company (a "Company Order").

          The Trustee may appoint an authenticating agent to
authenticate Securities.  An authenticating agent may
authenticate Securities whenever the Trustee may do so.  Each
reference in this Indenture to authentication by the Trustee
includes authentication by such agent.  An authenticating agent
has the same rights as an Agent to deal with the Company or an
Affiliate.

          The Securities shall be issuable only in registered
form without coupons.  The Securities shall be issuable only in
denominations of $1,000 principal amount and any whole multiples
thereof.

SECTION 2.3.  Registrar and Agents.
          The Company shall maintain an office or agency where
Securities may be presented for registration of transfer or for
exchange ("Registrar"), an office or agency where Securities may
be presented for payment ("Paying Agent"), an office or agency
where Securities may be presented for conversion ("Conversion
Agent") and an office or agency where notices and demands to or
upon the Company in respect of the Securities and this Indenture
may be served.  The Registrar shall keep a register of the
Securities (the "Security Register") and of their transfer and
exchange.  The Company may have one or more co-registrars, one or
more additional Paying Agents and one or more additional
Conversion Agents.  The Company or any Subsidiary may act as
Paying Agent and/or Conversion Agent.  The term "Paying Agent"
includes any additional paying agent and the term "Conversion
Agent" includes any additional conversion agent.

          The Company may change any Paying Agent, Registrar,
Conversion Agent or Co-Registrar on sixty (60) days' prior
written notice to the Trustee.  The Company shall notify the
Trustee in writing of the name and address of any such Agent.  If
the Company fails to maintain a Registrar, Paying Agent,
Conversion Agent or agent for service of notices and demands, or
fails to give the foregoing notice, the Trustee shall act as
such.

          The Company initially appoints the Trustee as
Registrar, Paying Agent, Conversion Agent and agent for service
of notices and demands.

SECTION 2.4.  Paying Agent to Hold Money in Trust.
          At least one Business Day prior to each due date of the
principal of, premium if any, and interest on any Securities, the
Company shall deposit with each Paying Agent a sum in immediately
available funds sufficient to pay such principal, premium, if
any, and interest so becoming due.  The Company shall require
each Paying Agent other than the Trustee to agree in writing that
it will hold in trust for the benefit of Holders of Securities or
the Trustee all money held by the Paying Agent for the payment of
principal of, premium if any, or interest on the Securities and
to notify the Trustee of any default by the Company (or any other
obligor on the Securities) in making any such payment.  If the
Company or a Subsidiary acts as Paying Agent, it shall on or
before each due date of the principal of, premium, if any, or
interest on any Securities segregate the money and hold it as a
separate trust fund.  The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and the
Trustee may at any time during the continuance of any payment
default, upon written request to a Paying Agent, require such
Paying Agent to forthwith pay in immediately available funds to
the Trustee all sums so held in trust by such Paying Agent.  Upon
doing so, the Paying Agent (if other than the Company or a
Subsidiary thereof) shall have no further liability for the
money.

          The final installment of principal of and premium, if
any, on each Security shall be payable only upon surrender of
such Security at the office or agency of the Company maintained
for such purpose.  Payments of principal and premium, if any, and
interest on a Security shall be made at the office or agency of
the Company maintained for such purpose, or, in the case of any
such payments other than the final payment of principal and
premium, if any, at the Company's option, by check mailed to the
Person entitled thereto at such Person's address last appearing
on the Security Register maintained by the Registrar.

SECTION 2.5.  Transfer and Exchange.
          (1)  When a Security is presented to the Registrar or a
co-registrar with a request to register the transfer thereof, the
Registrar or co-registrar shall register the transfer as
requested, and when Securities are presented to the Registrar or
a co-registrar with a request to exchange them for an equal
principal amount of Securities of other authorized denominations,
the Registrar shall make the exchange as requested provided that
every Security represented or surrendered for registration of
transfer or exchange shall be duly endorsed and accompanied by a
written instrument of transfer satisfactory to the Company and
the Registrar duly executed by the Holder or such Holder's
attorney-in-fact duly authorized in writing; provided, further,
that the Registrar or co-registrar, as the case may be, shall not
register the transfer of such Security if such Security is a
Restricted Security unless the conditions in Section 2.5(2)
hereof shall have been satisfied.  The Holder of each Security,
including each Restricted Security, by such Holder's acceptance
thereof, agrees to be bound by the transfer restrictions set
forth herein and in the legend on such Security.

          (2)  Whenever any Restricted Security is presented or
surrendered for registration of transfer or exchange for a
Security registered in a name other than that of the Holder, no
registration of transfer or exchange shall be made unless:

                    (a)  The registered Holder presenting such
          Restricted Security for transfer shall have certified
          to the Trustee in writing that the registered Holder is
          transferring the Restricted Security to the Company; or
          
                    (b)  The Trustee has received written
          certification from the registered Holder, and a written
          opinion of counsel acceptable in form and substance to
          the Company and the Trustee, indicating that the
          transfer is being made pursuant to an available
          exemption from, or a transaction not otherwise subject
          to, the registration requirements of the Securities
          Act.
          
          For purposes of this Section 2.5(2), such certification
to the Trustee in writing shall be in the form of the Transfer
Notice set forth on the reverse of such Security.  The Trustee
shall be fully protected in relying on, and may assume
conclusively the correctness of the statement made in, any
certificate given pursuant to the Section 2.5(2).

          (3)  Each certificate evidencing Restricted Securities
shall bear a legend in substantially this following form:

          THIS SECURITY HAS BEEN ACQUIRED BY THE HOLDER FOR THE
          PURPOSE OF INVESTMENT AND NOT WITH A VIEW TO OR FOR
          SALE IN CONNECTION WITH ANY DISTRIBUTION.  THIS
          SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED

          HEREIN MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE
          EXEMPTION THEREFROM.  EACH PURCHASER OF THIS SECURITY
          IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON AN
          EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE
          SECURITIES ACT.  THE HOLDER OF THIS SECURITY, BY ITS
          ACCEPTANCE HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES
          FOR THE BENEFIT OF THE COMPANY THAT: (I) IT HAS
          ACQUIRED A "RESTRICTED" SECURITY WHICH HAS NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT; (II) IT WILL NOT
          OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT
          (A) TO COMPTEK RESEARCH, INC., (B) PURSUANT TO A
          REGISTRATION STATEMENT WHICH HAS BEEN DECLARED
          EFFECTIVE UNDER THE SECURITIES ACT, OR (C) IN
          ACCORDANCE WITH RULE 144 UNDER THE SECURITIES ACT OR
          PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE
          REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, (AND
          CONFIRMED IN AN OPINION OF COUNSEL ACCEPTABLE IN FORM
          AND SUBSTANCE TO THE ISSUER OF THIS SECURITY IF THE
          ISSUER SO REQUESTS) AND, IN EACH CASE, IN ACCORDANCE
          WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF THE
          UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION; AND
          (III) IT WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED
          TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF
          THE RESALE RESTRICTIONS SET FORTH IN (II) ABOVE.
          
Subject to compliance with Section 2.5(6) hereof, the above
legend may be removed from a certificate when it no longer
evidences a Security which is a Restricted Security.

          (4)  To permit registrations of transfers and
exchanges, the Company shall issue and the Trustee or any
authenticating agent shall authenticate Securities at the
Registrar's or co-registrar's request.  No service charge to any
Holder shall be made for any registration of transfer or exchange
of Securities but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may
be imposed in relation thereto, but this provision shall not
apply to any exchange pursuant to Section 2.8, 3.6, 9.5 or 10.2
not involving any transfer.

          (5)  The Registrar shall not be required (i) to issue,
register the transfer of or exchange Securities during a period
beginning at the opening of business 15 days before the day of
any selection of Securities for redemption under Section 3.2 and
ending at the close of business on the day of selection, or
(ii) to register the transfer or exchange of any Security so
selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

          (6)  Any Restricted Security as to which the
restrictions on transfer set forth in Section 2.5(2) hereof shall
have expired in accordance with their terms or shall have
terminated may, upon surrender of such Restricted Security for
exchange to the Trustee in accordance with the provisions of this
Section 2.5(6) (accompanied, in the event that such restrictions
on transfer have terminated by reason of a transfer pursuant to
Rule 144 (or any successor provision), by an opinion of counsel
reasonably acceptable to the Company, addressed to the Company
and the Trustee and in form and scope reasonably satisfactory to
the Company, to the effect that the transfer of such Restricted
Security has been made in compliance with Rule 144 (or such
successor provision)), be exchanged for a new Security, of like
tenor and aggregate principal amount, which shall not bear the
restrictive legend required by Section 2.5(3) hereof.  The
Company shall promptly inform the Trustee in writing of the
effective date of any registration statement registering the
Securities under the Securities Act.

           (7) All notices and communications to be given to the
Holders and all payments to be made to Holders under the
Securities shall be given or made only to the registered Holders
as shown on the list of Holders maintained by the Registrar and
otherwise in accordance with the provisions of this Indenture.

          The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under
applicable law with respect to any transfer of any interest in
any Security other than to require delivery of such certificates
and other documentation or evidence as are expressly required by,
and to do so if and when expressly required by, the terms of this
Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof.

SECTION 2.6.  Replacement Securities.
          If a mutilated Security is surrendered to the Trustee
or if the Holder of a Security presents evidence to the
satisfaction of the Company and the Trustee that the Security has
been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a new Security in replacement
of and substitution for such Security if the requirements of the
Trustee and the Company are met.  An indemnity bond may be
required by the Company or the Trustee that is sufficient in the
judgment of the Company to protect the Company and is sufficient
in the judgment of the Trustee to protect the Trustee or any
Agent from any loss which it may suffer if a Security is replaced
pursuant to this Section 2.6.  The Company and the Trustee may
charge for their respective expenses incurred in replacing a
Security.

          In case any such mutilated, destroyed, lost or stolen
Security has become or is about to become due and payable, the
Company in its sole discretion may, instead of issuing a new
Security, pay or authorize the payment or convert or authorize
the conversion of such Security.

          Every new Security issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute
an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security shall be at
any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any
and all other Securities duly issued hereunder.

SECTION 2.7.  Outstanding Securities.
          Securities outstanding at any time are all Securities
theretofore authenticated and delivered under this Indenture
except: (a) Securities theretofore canceled by the Trustee or
delivered to the Trustee for cancellation; and (b) Securities in
exchange for or in lieu of which other Securities have been
authenticated and delivered pursuant to this Indenture, other
than any Securities in respect of which there shall have been
presented to the Trustee proof satisfactory to it that such
Securities are held by a bona fide purchaser in whose hands such
Securities are valid obligations of the Issuer; provided, that in
determining whether the Securityholders of the requisite
principal amount of outstanding Securities are present at a
meeting of Securityholders for quorum purposes or have voted or
taken or concurred in any action under this Indenture, including
the making of any request, demand, authorization, direction,
notice, consent or waiver hereunder, Securities owned by the
Company or any other obligor upon the Securities or any Affiliate
of the Company or such other obligor shall be disregarded and
deemed not outstanding, except that, in determining whether the
Trustee shall be protected in relying upon any such determination
as to the presence of a quorum or upon any such request, demand,
authorization, direction, notice, consent or waiver, only
Securities which a Trust Officer of the Trustee actually knows to
be so owned shall be disregarded.

          If a Security is replaced pursuant to Section 2.6, it
ceases to be outstanding until the Trustee receives proof
satisfactory to it that the replaced Security is held by a bona
fide purchaser.

          If the Paying Agent (other than the Company or a
Subsidiary) holds on a Redemption Date or maturity date money
deposited with it by or on behalf of the Company sufficient to
pay the principal of, premium, if any, and accrued interest on
Securities payable on that date, then on and after that date such
Securities cease to be outstanding and interest on them ceases to
accrue.

          A Security does not cease to be outstanding because the
Company or an Affiliate holds the Security.

SECTION 2.8.  Temporary Securities.
          Until definitive Securities are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary
Securities.  Temporary Securities shall be substantially in the
form of definitive Securities but may have non-material
variations that the Company considers appropriate for temporary
Securities.  Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Securities
in exchange for temporary Securities upon written order of the
Company signed by two Officers.  Until so exchanged, temporary
Securities represent the same rights as definitive Securities.
Upon request of the Trustee, the Company shall provide an
Officers' Certificate to the effect that the temporary Securities
meet the requirements of the second sentence of this Section 2.8.

SECTION 2.9.  Cancellation.
          The Company at any time may deliver Securities to the
Trustee for cancellation.  The Registrar, the Paying Agent and
the Conversion Agent shall forward to the Trustee any Securities
surrendered to them for transfer, exchange, payment or
conversion.  The Trustee shall cancel all Securities surrendered
for transfer, exchange, payment or conversion and destroy
canceled Securities and deliver a certificate of such destruction
to the Company unless the Company directs the Trustee in writing
prior to such destruction to deliver canceled Securities to the
Company.  Subject to Sections 2.6, 3.6 and the second paragraph
of Section 10.2, the Company may not issue Securities to replace
Securities that it has previously paid or delivered to the
Trustee for cancellation or that a Securityholder has converted
pursuant to Article 10 hereof.

SECTION 2.10.  Defaulted Interest.
          If the Company defaults in a payment of interest on
Securities when the same becomes due and payable and such default
continues for a period of 30 days, it shall pay the defaulted
interest to the Persons who are Holders of the Securities on a
subsequent special record date.  After the deposit by the Company
with the Trustee of money sufficient to pay such defaulted
interest, the Trustee shall fix the special record date and
payment date.  Each such special record date shall be not less
than 10 days prior to such payment date.  Each such payment date
shall be not more than 60 days after the deposit by the Company
of money to pay the defaulted interest.  At least 15 days before
the special record date, the Company shall mail to each Holder of
a Security, with a copy to the Trustee, a notice that states the
special record date, the payment date, and the amount of
defaulted interest to be paid.

SECTION 2.11.  Securityholder Lists.
          The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of
the names and addresses of Securityholders, a copy of which list
shall be provided to the Company upon its written request.  If
the Trustee is not the Registrar, the Registrar shall furnish to
the Trustee at least seven Business Days prior to each semiannual
interest payment date and at such other times as the Trustee may
reasonably request in writing a list in such form and as of such
date as the Trustee may require of the names and addresses of
Securityholders upon which the Trustee may conclusively rely.
The Trustee may destroy any such list upon receipt of a
replacement list.  The Paying Agent will solicit from each
Securityholder a certification of social security number or
taxpayer identification number in accordance with its customary
practice and as required by law, unless the Paying Agent is in
possession of such certification.  Each Paying Agent is
authorized to impose back-up withholding with respect to payments
to be made to Securityholders to the extent required by law.

SECTION 2.12.  Persons Deemed Owners.
          Prior to registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of
such Security and neither the Company, the Trustee nor any Agent
of the Company or the Trustee shall be affected by notice to the
contrary.

                          ARTICLE III.
                           REDEMPTION
                                
SECTION 3.1.  Notices to Trustee.
          If the Company wants to redeem the Securities pursuant
to the optional redemption provisions of Paragraph 5 of the
Securities, it shall notify the Trustee of the Redemption Date
and the principal amount of Securities to be redeemed.  The
notice shall be given to the Trustee in writing at least 60 days
prior to the Redemption Date (unless a shorter notice period
shall be satisfactory to the Trustee in its discretion) and
accompanied by an Officers' Certificate stating that the
redemption complies with the provisions of this Indenture.
Redemptions provided for in Paragraph 5 of the Securities shall
be effected as provided in said Paragraph 5 or as otherwise
agreed upon by the Company and the Trustee.

SECTION 3.2.  Selection of Securities to be Redeemed.
          If less than all the Securities are to be redeemed, the
Trustee shall select the Securities to be redeemed by lot or by
any other method that the Trustee considers fair and appropriate
under the circumstances.  The Trustee shall promptly notify the
Company of the Securities to be so called for redemption.  The
Trustee shall make the selection from Securities outstanding and
not previously called for redemption.  The Trustee may select for
redemption portions of the principal of Securities that have
denominations larger than $1,000 principal amount.  Securities
and portions of them it selects shall be in principal amounts of
$1,000 or multiples thereof.  Provisions of this Indenture that
apply to Securities called for redemption also apply to portions
of Securities called for redemption.  The Trustee's selection of
Securities for redemption by any method authorized by this
Section 3.2 shall be conclusively deemed reasonable.

          Upon any redemption of less than all the Securities,
the Company and the Trustee, for the purpose of selecting
Securities to be redeemed, may treat as outstanding any
Securities surrendered for conversion during the period of 15
days next preceding the selection of the Securities and need not
treat as outstanding any Security authenticated and delivered
during such period in exchange for the unconverted portion of any
Security converted in part during such period.

SECTION 3.3.  Notice of Redemption by the Company.
          At least 30 days but not more than 60 days before a
Redemption Date, the Company shall mail a notice of redemption by
first-class mail to each Holder of Securities to be redeemed,
with a copy to the Trustee.

          The notice shall identify the Securities to be redeemed
and shall state:

               (1)       the Redemption Date;

               (2)       the Redemption Price;

                         (3)  the Conversion Price;
                    
               (4)       the name and address of the Paying Agent
          and the Conversion Agent;
          
               (5)       that Securities called for redemption
          may be converted at any time before the close of
          business on the Redemption Date and, if not converted
          prior to the close of business on the Redemption Date,
          the right of conversion will be lost;
          
               (6)       that Holders who want to convert
          Securities must satisfy the requirements of Paragraph 8
          thereof;
          
               (7)       that Securities called for redemption
          must be surrendered to the Paying Agent to collect the
          Redemption Price;
          
               (8)       that interest on Securities called for
          redemption ceases to accrue on and after the Redemption
          Date; and
          
               (9)       if any Security is being redeemed in
          part, the portion of the principal amount of such
          Security to be redeemed and that, after the Redemption
          Date, upon surrender of such Security, a new Security
          or Securities in principal amount equal to the
          unredeemed portion thereof will be issued.
          
          At the Company's written request, the Trustee shall
give the notice of redemption in the Company's name and at the
Company's expense.  If a CUSIP number is listed in such notice or
printed on the Security, the notice shall state that no
representation is made as to the correctness or accuracy of such
CUSIP number.

SECTION 3.4.  Effect of Notice of Redemption.
          Once notice of redemption is mailed, Securities called
for redemption become due and payable on the applicable
Redemption Date and at the applicable Redemption Price.  Upon
surrender to the Paying Agent, such Securities shall be paid at
the Redemption Price, plus accrued interest to the Redemption
Date.

SECTION 3.5.  Deposit of Redemption Price.
          On or before the Redemption Date, the Company shall
deposit with the Paying Agent (or if the Company or a Subsidiary
is the Paying Agent, shall segregate and hold in trust or cause
such Subsidiary to segregate and hold in trust) in immediately
available funds money sufficient to pay the Redemption Price of
and accrued interest on all Securities to be redeemed on that
date.  The Trustee or the Paying Agent shall return to the
Company any money so deposited not required for that purpose.

SECTION 3.6.  Securities Redeemed in Part.
          Upon surrender of a Security that is redeemed in part,
the Trustee shall authenticate for the Holder, at the expense of
the Company, a new Security equal in principal amount to the
unredeemed portion of the Security surrendered.

                            COVENANTS
                                
SECTION 4.1.  Payment of the Securities.
          The Company shall pay the principal of, premium, if
any, and interest on the Securities on the dates and in the
manner provided in the Securities and this Indenture.  An
installment of principal, premium, if any, or interest shall be
considered paid on the date it is due if the Trustee or Paying
Agent (if other than the Company or a Subsidiary) holds on that
date money designated for and sufficient to pay the installment.
The Company shall pay interest on overdue principal and premium,
if any, at the rate borne by the Security; it shall pay interest,
including post-petition interest in the event of a proceeding
under any Bankruptcy Law, on overdue installments of interest at
the same rate to the extent lawful.

SECTION 4.2.  Commission Reports.
          The Company shall file with the Trustee, promptly after
filing with the Commission, copies of the annual reports and of
the information, documents and other reports (or copies of such
portions of any of the foregoing as the Commission may by rules
and regulations prescribe) which the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act.  The Company shall also comply with the other
provisions of TIA  314(a).

          So long as the Securities remain outstanding, the
Company shall cause its annual reports to stockholders
(containing audited financial statements) and any other financial
reports furnished by it to stockholders to be mailed to the
Holders at their addresses appearing in the Security Register
maintained by the Registrar.

SECTION 4.3.  Waiver of Stay, Extension or Usury Laws.
          The Company expressly waives (to the extent that it may
lawfully do so) any stay or extension law or any usury law or
other law that would prohibit or forgive the Company from paying
all or any portion of the principal of, premium, if any, or
interest on Securities as contemplated herein or in such
Securities, wherever enacted, now or at any time hereafter in
force, or that may affect the covenants or the performance of
this Indenture or the provisions of such Securities, and the
Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law
had been enacted.

SECTION 4.4.  Notice of Default.
          The Company will, so long as any Securities are
outstanding, deliver to the Trustee, within 10 days of becoming
aware of any Default or Event of Default in the performance of
any covenant, agreement or condition in this Indenture, an
Officers' Certificate specifying such Default or Event of
Default, the period of existence thereof and what action the
Company is taking or proposes to take with respect thereto.

SECTION 4.5.  Compliance Certificates.
          The Company will deliver to the Trustee, within 120
days after the end of each fiscal year of the Company (which as
of the date hereof is March 31), a written statement signed by
the principal executive officer, principal financial officer or
principal accounting officer of the Company, stating, as to each
signer thereof:

               (1)  that a review of the activities of the
          Company during such year and of performance under this
          Indenture has been made under his or her supervision;
          
               (2)  that to the best of his or her knowledge,
          based on such review, the Company has kept, observed,
          performed and fulfilled in all material respects each
          and every condition and covenant contained in this
          Indenture throughout such year, or, if there has been a
          default in the fulfillment of any such condition or
          covenant, specifying each such default known to him or
          her and the nature and status thereof; and
          
               (3)  the conversion price (as described in
          Article 10 of this Indenture) then in effect.
          
          The Company will give the Trustee written notice of a
change in the fiscal year of the Company, within a reasonable
time after such change is effected.

SECTION 4.6.  Limitation on Dividends and Other Distributions.
          The Company will not declare or pay any dividends or
make any distribution to holders of its Capital Stock (other than
dividends or distributions payable in Capital Stock of the
Company), or purchase, redeem or otherwise acquire or retire for
value any of its Capital Stock or permit any Subsidiary to
purchase, redeem or otherwise acquire or retire for value any of
the Company's Capital Stock if at the time of any of the
aforementioned actions an Event of Default has occurred and is
continuing or would exist immediately after giving effect to such
action.

          Notwithstanding the foregoing, the provisions of this
Section 4.6 will not prevent (i) the payment of any dividend
within 60 days after the date of declaration when the payment
would have complied with the foregoing provisions on the date of
declaration; or (ii) the retirement of any shares of the
Company's Capital Stock by exchange for, or out of the proceeds
of the substantially concurrent sale (other than to a Subsidiary)
of, other shares of its Capital Stock.

          SECTION 4.7. Investment Company Act of 1940.

          The Company is not, nor will it become, an "investment
company" or "promoter" or "principal underwriter" for an
"investment company," as such terms are defined in the Investment
Company Act of 1940, as amended, and the rules and regulations
thereunder.

          SECTION 4.8. Due Execution, Delivery and Performance of
the Indenture.

          The Company's execution, delivery and performance of
this Indenture and the Company's issuance of the Securities (a)
have been duly authorized under New York law by all requisite
corporate action by the Company, and (b) will not violate (1) any
law or the Articles of Incorporation or Bylaws, each as amended,
of the Company or of any subsidiaries of the Company.

          SECTION 4.9. Maintenance of Corporate Existence.

          While the Securities are outstanding, the Company shall
maintain its corporate existence.

          SECTION 4.10.  Failure to Timely Deliver Certificates
Upon Conversion.  If the Holder of any Security or Securities has
strictly complied with the conversion requirements set forth in
Article X of this Indenture, in the Security and in the form of
conversion notice attached to the Security and has not received
certificates for the shares of Common Stock such Holder is
entitled to receive in accordance with such conversion within
three (3) Business Days after the date of delivery of the
properly executed conversion notice and the Securities subject to
conversion, all as provided in Article X of this Indenture, in
the Security and in the form of conversion notice attached to the
Security (the third Business Day following the date of such
delivery being the "Delivery Date"), then, beginning with the
Business Day following the Delivery Date, the Company shall pay
to such Holder, in cash, a penalty payment calculated as follows:
The penalty payment will apply to the period beginning on the
Business Day after the Delivery Date and ending on the day the
Company delivers, or causes the delivery of, the certificates for
the shares of Common Stock subject to such conversion to the

SECTION 5.1.  When Company May Merge, etc.
          The Company shall not consolidate with or merge into,
or transfer all or substantially all of its assets to, another
Person in any transaction in which the Company is not the
continuing or surviving entity, unless (i) the resulting,
surviving or transferee Person is a corporation which assumes by
supplemental indenture, in form satisfactory to the Trustee, all
the obligations of the Company under the Securities and this
Indenture or is a reorganization within the meaning of Section
368(a)(1)(B) of the Internal Revenue Code of 1986, as amended;
(ii) such corporation is organized and existing under the laws of
the United States, a State thereof or the District of Columbia
although it in turn may be owned by a foreign entity;
(iii) immediately after giving effect to such transaction no
Default or Event of Default shall have happened and be continuing
and the Officers' Certificate referred to in the following clause
reflects that such Officers are not aware of any such Default or
Event of Default that shall have happened and be continuing, and
(iv) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indenture
comply with this Indenture, and thereafter all obligations of the
Company shall terminate.

SECTION 5.2.  Successor Corporation or Trust Substituted.
          Upon any consolidation or merger, or any transfer of
all or substantially all of the assets of the Company in
accordance with Section 5.1, the successor corporation formed by
such consolidation or into which the Company is merged or to
which such transfer is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor
corporation has been named as the Company herein; the Company
shall thereupon be relieved of any further obligation or
liability hereunder or upon the Securities; and the Company as
the predecessor corporation may thereupon or at any time
thereafter be dissolved, wound up or liquidated.  Such successor
corporation thereupon may cause to be signed, and may issue
either in its own name or in the name of Comptek Research, Inc.,
any or all of the Securities issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation,
instead of the Company, and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities which previously
shall have been signed and delivered by the Officers to the
Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and
delivered to the Trustee for that purpose.  All the Securities so
issued shall in all respects have the same legal rank and benefit
under this Indenture as the Securities theretofore or thereafter
issued in accordance with the terms of this Indenture as though
all such Securities had been issued at the date of the execution
hereof.

SECTION 6.1.  Events of Default.
          An "Event of Default", wherever used herein, means any
one of the following events (whatever the reason for such Event
of Default and whether it shall be occasioned by the provisions
of Article 11 or be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order or

or governmental body):

          payable and such default continues for a period of 30
          days or more;
          
               (2)  the Company defaults in the payment of the

          other material covenants, agreements or conditions in
          the Securities or this Indenture and such default
          continues for the period and after the notice specified
          in the last paragraph of this Section 6.1;
          
               (4)  there shall be a material default under any
          bond, debenture, note or other evidence of Indebtedness
          or under any mortgage, indenture or other instrument
          under which there may be issued or by which there may
          be secured or evidenced any Indebtedness of the Company
          or any Subsidiary, whether any such Indebtedness now
          exists or shall hereafter be created, if (a) either
          (i) such event of default results from the failure to
          pay any such Indebtedness at maturity or (ii) as a
          result of such event of default, the maturity of such
          Indebtedness has been accelerated prior to its stated
          maturity and such acceleration was not rescinded or
          annulled or the accelerated amount paid or discharged
          within ten days after notice to the Company of such
          acceleration, and (b) the principal amount of such
          Indebtedness, together with the principal amount of any
          other such Indebtedness in default for failure to pay
          principal or interest thereon, or the maturity of which
          has been so accelerated, aggregates $20,000,000 or
          more;
          
               (5)  the Company pursuant to or within the meaning
          of any Bankruptcy Law:
          
                         (a)  commences a voluntary case or
               proceeding,
               
                         (b)  consents to the entry of an order
               for relief against it in an involuntary case or
               proceeding,
               
                         (c)  consents to the appointment of a
               Custodian of it or for all or any substantial part
               of its property,
               
                         (d)  makes a general assignment for the
               benefit of its creditors; or
               
                         (e)  admits in writing its inability to
               pay its debts generally.
               
               (6)  a court of competent jurisdiction enters an
          order or decree under any Bankruptcy Law:
          
                         (a)  for relief against the Company in
               an involuntary case or proceeding,
               
                         (b)  appointing a Custodian of the
               Company or for all or substantially all of its
               property, or
               
                         (c)  ordering the liquidation of the
               Company,
               
          and the order or decree remains unstayed and in effect
          for 90 days.
          
               (7)  a Custodian shall be appointed out of Court
          with respect to the Company or all or any substantial
          part of its properties.
          
          A default under clause (3) is not an Event of Default
until the Trustee notifies the Company, or the Holders of a
majority in principal amount of the Securities then outstanding
notify the Company and the Trustee in writing, of the default and
the Company does not cure the default within 60 days after
receipt of such notice.  The notice must specify the default,
demand that it be remedied and state that the notice is a "Notice
of Default." The Trustee shall give such notice to the Company
only if directed to do so in writing by the Holders of a majority
in principal amount of the Securities then outstanding.  Such
notice by the Trustee shall not be deemed to be a certification
by the Trustee as to whether an Event of Default has occurred.

SECTION 6.2.  Acceleration.
          If an Event of Default (other than an Event of Default
specified in Section 6.1(5) or 6.1(6)) occurs and is continuing,
the Trustee by notice to the Company, or the Holders of a
majority in principal amount of the Securities then outstanding
by notice to the Company and the Trustee, may declare to be due
and payable immediately the principal amount of the Securities
plus accrued interest to the date of acceleration.  Upon any such
declaration, such amount shall be due and payable immediately,
and upon payment of such amount all of the Company's obligations
with respect to the Securities, other than obligations under
Section 7.7, shall terminate.  If an Event of Default specified
in Section 6.1(5) or 6.1(6) occurs, all unpaid principal and
accrued interest on the Securities then outstanding shall become
and be immediately due and payable without any declaration or the
act on the part of the Trustee or any Holder.  The Holders of a
majority in principal amount of the outstanding Securities by
written notice to the Trustee may rescind an acceleration and its
consequences if (x) all existing Events of Default, other than
the non-payment of the principal of the Securities, which have
become due solely by such declaration of acceleration, have been
cured or waived, (y) to the extent the payment of such interest
is lawful, interest on overdue installments of interest and
overdue principal and premium, if any, which has become due
otherwise than by such declaration of acceleration, has been
paid, and (z) the rescission would not conflict with any judgment
or decree of a court of competent jurisdiction.  The Trustee may
rely upon such notice of rescission without any independent
investigation as to the satisfaction of conditions (x), (y) and
(z).

SECTION 6.3.  Other Remedies.
          If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of and premium, if
any, or interest on the Securities or to enforce the performance
of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does
not possess any of the Securities or does not produce any of them
in the proceeding.  A delay or omission by the Trustee or any
Securityholder in exercising any right or remedy accruing upon an
Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.
No remedy is exclusive of any other remedy.  All available
remedies are cumulative.

SECTION 6.4.  Waiver of Defaults and Events of Default.
          Subject to Section 9.2, the Holders of a majority in
principal amount of the Securities then outstanding, on behalf of
all the Securityholders, by written notice to the Trustee may
waive a Default or Event of Default with respect to the
Securities and its consequences.  When a Default or Event of
Default is waived, it is considered to be cured and ceases to
exist; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.5.  Control by Majority.

          The Holders of a majority in principal amount of the
Securities then outstanding may direct in writing the time,
method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power
conferred on it.  The Trustee, however, may refuse to follow any
direction that conflicts with law or this Indenture, or that the
Trustee determines may be unduly prejudicial to the rights of
other Securityholders, it being understood that (subject to
Section 7.1) the Trustee shall have no duty to ascertain whether
or not such actions or forbearances are unduly prejudicial to
such Securityholders, or that may involve the Trustee in personal
liability or for which the Trustee does not have indemnification
reasonably satisfactory to the Trustee pursuant to Sections
7.1(5) and 7.2(6); provided that, the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent
with such direction.

SECTION 6.6.  Rights of Holders to Receive Payment.
Subject to Article 11, notwithstanding any other provision of
this Indenture, the right of any Securityholder to receive
payment of principal of, premium, if any, and interest on the
Security, on or after the respective due dates expressed in the
Security, or to bring suit for the enforcement of any such
payment on or after such respective dates, is absolute and
unconditional and shall not be impaired or affected without the
consent of the Holder.

          Notwithstanding any other provision of this Indenture,
the right of any Holder of any Security to convert such Security
or to bring suit for the enforcement of such right shall not be
impaired or affected without the written consent of the Holder.

SECTION 6.7.  Collection Suit by Trustee.

          If an Event of Default in payment of interest or
principal, and premium, if any, specified in Section 6.1(1) or
(2) occurs and is continuing, the Trustee may recover judgment in
its own name and as trustee of an express trust against the
Company or any other obligor on the Securities for the whole
amount of unpaid principal, and premium, if any, and accrued
interest remaining unpaid on the Securities, together with
interest on overdue principal, and premium, if any, and to the
extent that payment of such interest is lawful, interest on
overdue installments of interest, in each case at the rate borne
by the Securities and such further amount as shall be sufficient
to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

SECTION 6.8.  Trustee May File Proofs of Claim.
          The Trustee may file such proofs of claim and other
papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and the Holders of
Securities allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Securities), its creditors
or its property and shall be entitled and empowered to collect
and receive any monies or other property payable or deliverable
on any such claims and to distribute the same.  Any Custodian in
any such judicial proceeding is hereby authorized by each
Securityholder to make such payments to the Trustee, and in the
event that the Trustee shall consent to the making of such
payments directly to the Holders of Securities, to pay to the
Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section
7.7.

          Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on
behalf of any Securityholder any plan or reorganization,
arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Securityholder in any such
proceedings.

SECTION 6.9.  Priorities.
          If the Trustee collects any money pursuant to this
Article 6, it shall pay out the money in the following order:

          FIRST:    to the Trustee amounts due under Section 7.7;

          SECOND:   to holders of any Senior Indebtedness as
required by Article 11;

          THIRD:    to the Holders of the Securities for amounts
          due and unpaid on the Securities for principal,
          premium, if any, Repurchase Price, if any, and
          interest, ratably, without preference or priority of
          any kind, according to the amounts due and payable on
          the Securities for principal, premium, if any, and
          interest, respectively; and
          
          FOURTH:   to the Company.
          
          The Trustee may fix a record date and payment date for
any payment to Holders of Securities pursuant to this Section
6.9.

SECTION 6.10.  Undertaking for Costs.
          In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the
suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including
reasonable attorney's fees, against any party litigant in the
suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section 6.10
does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.6 or a suit by Holders of more than 10% in
principal amount of the Securities then outstanding or a suit by
any holder of Senior Indebtedness.

SECTION 6.11.  Limitation on Suits.
          A Securityholder may not pursue any remedy with respect
to this Indenture or the Securities unless:

               (1)  the Holder gives to the Trustee written
          notice stating that an Event of Default is continuing;
          
               (2)  the Holders of at least 25% in aggregate
          principal amount of the Securities at the time
          outstanding make a written request to the Trustee to
          pursue the remedy or initiate proceedings in respect of
          an Event of Default;
          
               (3)  such Holder or Holders offer to the Trustee
          security or indemnity against any loss, liability or
          expense satisfactory to the Trustee;
          
               (4)  the Trustee does not comply with the request
          within 60 days after receipt of notice, the request and
          the offer of security or indemnity; and
          
               (5)  the Holders of a majority in aggregate
          principal amount of the Securities at the time
          outstanding do not give the Trustee a direction
          inconsistent with the request during such 60-day
          period.
          
          A Securityholder may not use this Indenture to
prejudice the rights of any other Securityholder or to obtain a
preference or priority over any other Securityholder.  Rights and
Remedies available to the SecurityHolder under this Indenture are
cumulative.  Any delay or omission with respect to a Right or
Remedy shall not constitute waiver of such Right or Remedy.


                          ARTICLE VII.
                             TRUSTEE
                                
SECTION 7.1.  Duties of Trustee.
          (1)  The duties and responsibilities of the Trustee
shall be as provided by the TIA.  If an Event of Default has
occurred and is continuing, the Trustee shall exercise its rights
and powers vested in it by this Indenture and use the same degree
of care and skill in their exercise as a prudent Person would
exercise or use under the circumstances in the conduct of his own
affairs.

          (2)  Except during the continuance of an Event of
Default and after the curing or waiving of all such Events of
Default which may have occurred:

               (a)  The Trustee need perform only those duties
          that are specifically set forth in this Indenture, and
          the Trustee shall not be liable except for the
          performance of such duties as are specifically set
          forth in this Indenture, and no others, and no implied
          covenants or obligation shall be read into this
          Indenture against the Trustee.
          
               (b)  In the absence of bad faith on its part, the
          Trustee may conclusively rely, as to the truth of the
          statements and the correctness of the opinions
          expressed therein, upon any statements, certificates or
          opinions furnished to the Trustee and conforming to the
          requirements of this Indenture.  The Trustee, however,
          shall examine the certificates and opinions to
          determine whether or not they conform to the
          requirements of this Indenture.
          
          (3)  The Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act, or
its own willful misconduct, except that:

               (a)  This paragraph does not limit the effect of
          paragraph (2) of this Section 7.1.
          
               (b)  The Trustee shall not be liable for any error
          in judgment made in good faith by a Trust Officer,
          unless it is proved that the Trustee was negligent in
          ascertaining the pertinent facts.
          
               (c)  The Trustee shall not be liable with respect
          to any action it takes or omits to take in good faith
          in accordance with a direction received by it pursuant
          to Section 6.5.
          
               (d)  No provision of this Indenture shall require
          the Trustee to expend or risk its own funds or
          otherwise incur any financial liability in the
          performance of any of its duties hereunder or in the
          exercise of any of its rights or powers, if it shall
          have reasonable grounds for believing that repayment of
          such funds or adequate indemnity against such risk or
          liability is not reasonably assured to it.
          
          (4)  Every provision of this Indenture that in any way
relates to the Trustee is subject to paragraphs (1), (2) and (3)
of this Section 7.1 and subject to Sections 315 and 316 of the
TIA.

          (5)  Subject to subsection (3), the Trustee may refuse
to perform any duty or exercise any right or power unless,
subject to the provisions of the TIA, it receives indemnity
satisfactory to it against any loss, liability, expense or fee.

          (6)  The Trustee shall not be liable for interest on
any money received by it.  Money held in trust by the Trustee
need not be segregated from other funds except to the extent
required by law.

SECTION 7.2.  Rights of Trustee.
          (1)  The Trustee may rely on and shall be protected in
acting or refraining from acting upon any document believed by it
to be genuine and to have been signed or presented by the proper
Person.  The Trustee need not investigate any fact or matter
stated in the document.

          (2)  Before the Trustee acts or refrains from acting,
it may require an Officers' Certificate or an Opinion of Counsel,
or both, which shall conform to Section 13.5.  The Trustee shall
not be liable for any action it takes or omits to take in good
faith in reliance on such Officers' Certificate or Opinion of
Counsel.

          (3)  The Trustee may act through agents or attorneys
and shall not be responsible for the misconduct or negligence of
such agents or attorneys appointed with due care and shall not be
responsible for their supervision.

          (4)  The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be
authorized or within its rights or powers.

          (5)  The Trustee may consult with counsel of its choice
and the written advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by the Trustee
hereunder in good faith and reliance thereon.

          (6)  The Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by this
Indenture at the request or direction of any of the Holders of
Securities pursuant to this Indenture, unless such Holders shall
have offered to the Trustee security or indemnity satisfactory to
the Trustee against the costs, expenses and liabilities which
might be incurred by it in compliance with such request or
direction.

SECTION 7.3.  Individual Rights of Trustee.
          The Trustee in its individual or any other capacity may
become the owner or pledgee of Securities and may otherwise deal
with the Company or its Affiliates with the same rights it would
have if it were not Trustee.  Any Agent may do the same with like
rights.  The Trustee, however, is subject to Sections 7.10 and
7.11.

SECTION 7.4.  Trustee's Disclaimer.
          The Trustee makes no representation as to the validity
or adequacy of this Indenture or the Securities, it shall not be
accountable for the Company's use of the proceeds from the
Securities, and it shall not be responsible for any statement of
the Company in the Indenture or any statement in the Securities
other than its certificate of authentication or in any document
used in the sale of the Securities other than any statement in
writing provided by the Trustee expressly for use in such
document.

SECTION 7.5.  Notice of Defaults.
          If a Default or Event of Default occurs and is
continuing and if such Default or Event of Default is actually
known to the Trustee, the Trustee shall mail to each Holder of
Securities notice of the Default or Event of Default within 90
days after it becomes known to the Trustee.  Except in the case
of a default in payment of principal of, premium, if any, or
interest on any Security, the Trustee may withhold the notice if
and so long as a committee of its Trust Officers in good faith
determines that withholding the notice is in the interests of
Holders of Securities.  Notwithstanding anything to the contrary
expressed in this Indenture, the Trustee shall not be deemed to
have knowledge of any Event of Default hereunder unless and until
a Trust Officer shall have actual knowledge thereof, or shall
have received written notice thereof from the Company at its
principal Corporate Trust Office as specified in Section 13.2.
The Trustee shall not be deemed to have actual knowledge of an
Event of Default hereunder, except in the case of an Event of
Default under Sections 6.1(1) or 6.1(2) (provided that the
Trustee is the Paying Agent), until a Trust Officer receives
written notice thereof from the Company or any Securityholder
that such a Default or an Event of Default has occurred.

SECTION 7.6.  Reports by Trustee to Holders.
          Within 60 days after each May 15 beginning with May 15
of the first year in which Securities are outstanding hereunder,
the Trustee, if required by the provisions of TIA  313(a), shall
mail to each Securityholder a brief report dated as of May 15 of
such year that complies with TIA  313(a).  The Trustee also
shall comply with TIA  313(b),  313(c) and  313(d).

          A copy of each report at the time of its mailing to
Securityholders shall be filed with the Securities and Exchange
Commission and each securities exchange, if any, on which the
Securities are listed.  The Company agrees to notify the Trustee
in writing whenever the Securities become listed or delisted on
or from any securities exchange.

SECTION 7.7.     Compensation and Indemnity
          The Company shall pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation for
its services (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an
express trust).  The Company shall reimburse the Trustee upon
request for all reasonable disbursements, expenses and advances
incurred or made by it.  Such expenses may include, but shall not
be limited to, the reasonable compensation, disbursements and
expenses of the Trustee's agents, consultants and counsel.

          The Company shall indemnify and defend the Trustee and
its officers, directors, stockholders, agents and employees for,
and hold them harmless against, any loss or liability incurred by
it in connection with the acceptance or administration of this
trust, including the costs and expenses of defending themselves
against any claim or liability in connection with the Securities
or the exercise or performance of any of the Trustee's powers or
duties hereunder.  The Trustee shall notify the Company promptly
of any claim asserted against the Trustee for which it may seek
indemnity; provided, however, that any failure to so notify the
Company shall not relieve the Company of its indemnity
obligations hereunder except to the extent the Company's ability
to defend such claim shall be prejudiced thereby.  The Company
shall assume the defense of any such claim at the Company's
expense with counsel reasonably satisfactory to the Trustee;
provided, however, that if the Trustee is advised by counsel that
the interests of the Company and the Trustee conflict, the
Trustee shall have the right to retain separate counsel at the
expense of the Company.

          The Company need not reimburse the Trustee for any
expense or indemnify it against any loss or liability incurred by
it through the Trustee's proven negligence or willful misconduct.
The Company shall not be liable for any settlement of any claim
or action effected without the Company's consent, which consent
shall not be unreasonably withheld.  To secure the Company's
payment obligations in this Section, the Trustee shall have a
lien prior to the Securities on all money or property held or
collected by the Trustee or any Paying Agent.

          When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 6.1 occurs, the
expenses and the compensation for the services are intended to
constitute expenses of administration under any applicable
bankruptcy or comparable law.  The provisions of this Section
shall survive termination of this Indenture.

SECTION 7.8.  Replacement of Trustee.
          A resignation or removal of the Trustee and appointment
of a successor Trustee shall become effective only upon the
successor Trustee's acceptance of appointment as provided in this
Section 7.8.

          The Trustee may resign by so notifying the Company in
writing at least 30 days prior to the date such resignation shall
become effective as specified therein.  The Holders of a majority
in principal amount of the Securities then outstanding may remove
the Trustee by so notifying the Trustee in writing and may
appoint a successor Trustee with the Company's written consent,
which consent will not be unreasonably withheld.  The Company may
remove the Trustee if:

               (1)  the Trustee fails to comply with Section
          7.10;
          
               (2)  the Trustee is adjudged a bankrupt or an
          insolvent;
          
               (3)  a receiver or other public officer takes
          charge of the Trustee or its property; or
          
               (4)  the Trustee otherwise becomes incapable of
          acting.
          
          If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company shall
promptly appoint a successor Trustee, unless a successor Trustee
is appointed by the Holders in accordance with this Indenture.

          If a successor Trustee does not take office within 45
days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Company or the Holders of a majority in
principal amount of the Securities then outstanding may petition
any court of competent jurisdiction for the appointment of a
successor Trustee.

          If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor
Trustee.

          A successor Trustee shall deliver a written acceptance
of its appointment to the retiring Trustee and to the Company.
Immediately after that, the retiring Trustee shall, upon payment
of its fees and expenses, transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided
for in Section 7.7, the resignation or removal of the retiring
Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this
Indenture.  Notwithstanding the replacement of the Trustee
pursuant to this Section 7.8, the Company's obligations under
Section 7.7 shall continue for the benefit of the retiring
Trustee with respect to its administration of the trusts
hereunder, including without limitation, the rights of the
retiring Trustee to indemnification and its rights to receive
expenses incurred by it and compensation earned by it under or
pursuant to the Indenture.  A successor Trustee shall mail notice
of its succession to each Holder of Securities.

SECTION 7.9.  Successor Trustee by Merger, etc.
          If the Trustee consolidates with, merges or converts
into, or transfers all or substantially all of its corporate
trust assets to, another corporation, the successor corporation
without any further act shall be the successor Trustee.

SECTION 7.10.  Eligibility; Disqualification.
          This Indenture shall always have a Trustee who
satisfies the requirements of TIA  310(a)(1).  The Trustee shall
have a combined capital and surplus of at least $50,000,000 as
set forth in its most recent published annual report of
condition.  The Trustee shall comply with TIA  310(b), including
the optional provision permitted by the second sentence of TIA
 310(b)(9).  The Trustee shall be organized in the United States
or any state thereof, shall be authorized to execute the
corporate trustee powers and shall be subject to supervision or
regulation by a federal or state authority.

SECTION 7.11.  Preferential Collection of Claims Against Company.
          The Trustee is subject to TIA  311(a), excluding any
creditor relationship listed in TIA  311(b).  A Trustee who has
resigned or been removed shall be subject to TIA  311(a) to the
extent indicated therein.

                          ARTICLE VIII.
             SATISFACTION AND DISCHARGE OF INDENTURE

Securities, and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and
discharge of such indebtedness; provided that the following
conditions shall have been satisfied:

               (1)  the Company has deposited or caused to be
          deposited with the Trustee irrevocably as trust funds
          in trust, specifically pledged as security for, and
          dedicated solely to, the benefit of the Holders of the
          Securities, with reference to this Section 8.1,
          (a) money or (b) U.S. Government Obligations or (c) a
          combination thereof, sufficient, in the opinion of a
          nationally recognized firm of independent public
          accountants expressed in a written certification
          thereof delivered to the Trustee, to pay and discharge
          the entire indebtedness on all the Securities for
          principal, premium, if any, and interest, if any, to
          the maturity date of the Securities as such principal,
          premium, if any, or interest becomes due and payable in
          accordance with the terms of this Indenture and the
          Securities;
          
               (2)  the Company has paid or caused to be paid all
          other sums payable hereunder by the Company in

          entire Indebtedness on the Securities and the discharge
          of this Indenture and the termination of the Company's
          obligations hereunder have been complied with.
          
          "U.S. Government Obligations" means direct, non-
callable obligations of, or non-callable obligations guaranteed
by, the United States of America for the timely payment of which
obligation or guarantee the full faith and credit of the United
States of America is pledged.

SECTION 8.2.  Satisfaction and Discharge of Indenture.
          In addition to its rights under Section 8.1, the
Company may terminate all of its obligations under this Indenture
when:

               (1)  all of the Securities theretofore
          authenticated and delivered (other than (a) Securities
          which have been destroyed, lost or stolen and which
          have been replaced or paid as provided in Section 2.6
          hereof and (b) Securities for whose payment money has
          theretofore been deposited with the Trustee or the
          Paying Agent in trust or segregated and held in trust
          by the Company and thereafter repaid to the Company or
          discharged from such trust, as provided in Section 2.4
          and Section 8.6 hereof) have been delivered to the

               (2)  the Company has paid or caused to be paid all
          other sums payable hereunder by the Company in
          connection with the outstanding Securities, including
          all fees and expenses of the Trustee.
          
SECTION 8.3.  Survival of Certain Obligations.
          Notwithstanding the satisfaction and discharge of this
Indenture pursuant to Section 8.1, the respective obligations of
the Company specified in Sections 2.3, 2.4, 2.5, 2.6, 2.11, 4.1,
7.7, 8.5, 8.6, 8.7 and in Article 10 shall survive until the
Securities are no longer outstanding, and after the Securities
are no longer outstanding, or upon compliance with Section 8.2,
only the obligations of the Company in such Sections 7.7 and 8.6
shall survive.  Nothing contained in this Article 8 shall
abrogate any of the obligations or duties of the Trustee under
this Indenture.

SECTION 8.4.  Application of Trust Money.
          (1)  Subject to the provisions of Section 8.6, all
money and U.S. Government Obligations deposited with the Trustee
for the Securities pursuant to Section 8.1 or Section 8.2, and
all money received by the Trustee in respect of U.S. Government
Obligations deposited with the Trustee for the Securities
pursuant to Section 8.1 or Section 8.2 shall be held in trust and
reinvested by the Trustee in (a) U.S. Government Obligations or
(b) beneficial interests in one or more mutual funds which invest
all or substantially all of their assets in U.S. Government
Obligations and which are rated in the highest applicable rating
category by a nationally-recognized statistical rating
organization in accordance with the Company's written
instructions and applied by the Trustee in accordance with the
provisions of the Securities and this Indenture, to the payment,
either directly or through any Paying Agent (including the
Company or any Subsidiary acting as Paying Agent) as the Trustee
may determine, to the Persons entitled thereto, of the principal,
premium, if any, and interest, if any, on the Securities; but
such money need not be segregated from other funds except to the
extent required by law.  Money and U.S. Government Obligations so
held in trust are not subject to the subordination provisions of
Article 11.

          (2)  The Trustee shall deliver or pay to the Company
from time to time upon the Company's written request any U.S.
Government Obligations or money held by it as provided in Section
8.1 or Section 8.2 which, in the written opinion of a nationally
recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are then
in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such U.S.
Government Obligations, or money, were deposited or received.

SECTION 8.5.  Paying Agent to Repay Monies Held.
          Upon the satisfaction and discharge of this Indenture,
all monies then held by any Paying Agent under the provisions of
this Indenture shall, upon written demand of the Company, be
repaid to it or paid to the Trustee, and thereupon such Paying
Agent shall be released from all further liability with respect
to such monies.

SECTION 8.6.  Return of Unclaimed Monies.
          Any monies deposited with or paid to the Trustee or any
Paying Agent for the Securities, or then held by the Company in
trust, for the payment of any principal, premium, if any, and
interest, if any, on the Securities and not applied but remaining
unclaimed by the Holders of the Securities for two years after
the date upon which the principal of, premium, if any, and
interest, if any, on the Securities, as the case may be, shall
have become due and payable, shall, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or
unclaimed property law, be repaid to the Company by such Trustee
or any Paying Agent on written demand by the Company or (if then
held by the Company or any Affiliate) shall be discharged from
such trust; and the Holders of the Securities entitled to receive
such payment shall thereafter look only to the Company for the
payment thereof; provided, however, that, before being required
to make any such repayment, the Trustee may, or shall at the
written request of the Company, at the expense of the Company,
cause to be published once in an authorized newspaper in the same
city in which the place of payment with respect to the Securities
shall be located and in an authorized newspaper in the City of
New York, or mail to each such Holder, a notice (in such form as
may be deemed appropriate by the Trustee) that said monies remain
unclaimed and that, after a date named therein, any unclaimed
balance of said monies then remaining will be returned to the
Company.

SECTION 8.7.  Reinstatement.
          If the Trustee or Paying Agent is unable to apply any
money or U.S. Government Obligations in accordance with Section
8.1 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.1 until such time as the Trustee or Paying
Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 8.4; provided, however,
that if the Company has made any payment of principal of,
premium, if any, or interest on the Securities because of the
reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

SECTION 8.8.  Indemnity for Government Obligations.
          The Company shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against U.S.
Government Obligations deposited with the Trustee pursuant hereto
or the principal and interest received on such U.S. Government
Obligations.

                           ARTICLE IX.
                     AMENDMENTS AND WAIVERS
                                
SECTION 9.1.  Amendments and Waivers Without Consent of Holders.
          The Company, when authorized by Board Resolution, and
the Trustee at any time and from time to time, may amend or
supplement this Indenture, (any such amendment or supplement to
be in a form satisfactory to the Trustee) or the Securities
without notice to or consent of any Securityholder for any of the
following purposes:

               (1)  to comply with Section 5.1; or
          
               (2)  to provide for uncertificated Securities in
          addition to or in place of certificated Securities; or
          
               (3)  to cure any ambiguity, defect or
          inconsistency, or to make any other change that does
          not adversely affect the interests or rights of the
          Holders of Securities; or
          
               (4)  to add to the covenants of the Company, for
          the benefit of the Holders or to surrender any right or
          power herein conferred upon the Company; or
          
               (5)  to add any Event of Default.
          
          The Trustee shall be entitled to receive upon request
an Officers' Certificate and an Opinion of Counsel to its
satisfaction with respect to any supplement to this Indenture
without consent of the Holders that all conditions precedent have
been satisfied.

SECTION 9.2.  Amendments and Waivers with Consent of Holders.
          With the written consent of the Holders of not less
than 66-2/3% in aggregate principal amount of the Securities at
the time outstanding, the Company, when authorized by Board
Resolution, and the Trustee may amend or supplement this
Indenture (any such amendment or supplement to be in a form
satisfactory to the Trustee) or the Securities for the purpose of
adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of any supplemental
indenture or of modifying in any manner the rights of the Holders
of the Securities.  The Holders of a majority in principal amount
of the Securities then outstanding may waive compliance in a
particular instance by the Company with any provision of this
Indenture or the Securities without notice to any Securityholder.
Subject to Section 9.4, without the consent of each Holder of
Securities affected, however, an amendment, supplement or waiver,
including a waiver pursuant to Section 6.4, may not:

               (1)  reduce the amount of Securities whose Holders
          must consent to an amendment or waiver;
          
               (2)  reduce the rate of or extend the time for
          payment of interest on any Security;
          
               (3)  reduce the principal of or extend the fixed
          maturity of any Security;
          
               (4)  waive (except unless theretofore cured) a
          default in the payment of the principal of (and
          premium, if any on), interest on or redemption amounts
          with respect to any Security;
          
               (5)  make any Security payable in currency other
          than that stated in the Security;
          
               (6)  make any change in Sections 6.4, 6.6 or 9.2;
          
               (7)  make any change that adversely affects the
          right to convert any Security;
          
               (8)  make any change in Article 11 that adversely
          affects the rights of any Securityholder; or
          
               (9)  impair the right of any Holder to institute
          any suit or proceeding.
          
          To secure a consent of the Holders under this Section,
it shall not be necessary for the Holders to approve the
particular form of any proposed amendment or waiver; rather, it
shall be sufficient if such consent approves the substance
thereof.

          After an amendment under this Section becomes
effective, the Company shall mail to Securityholders a notice
briefly describing such amendment.

SECTION 9.3.  Compliance with Trust Indenture Act.
          Every amendment or supplement to this Indenture or the
Securities shall comply with the TIA as then in effect.

SECTION 9.4.  Revocation and Effect of Consents.
          Subject to this Indenture, each amendment, supplement
or waiver evidencing other action shall become effective in
accordance with its terms.  Until an amendment, supplement or
waiver becomes effective, a consent to it by a Holder of a
Security is a continuing consent by the Holder even if notation
of the consent is not made on any Security.  Any such Holder or
subsequent Holder, however, may revoke the consent as to his
Security or portion of a Security, if the Trustee receives the
notice of revocation before the date the amendment, waiver or
other action becomes effective.

          The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled
to consent to any amendment, supplement or waiver.  If a record
date is fixed, then notwithstanding the provisions of the
immediately preceding paragraph, those Persons who were Holders
at such record date (or their duly designated proxies) and only
those Persons, shall be entitled to consent to such amendment,
supplement or waiver or to revoke any consent previously given,
whether or not such Persons continue to be Holders after such
record date.  No consent shall be valid or effective for more
than 90 days after such record date unless consent from Holders
of the principal amount of Securities then outstanding required
hereunder for such amendment, supplement or waiver to be
effective shall have also been given and not revoked within such
90-day period.

          After an amendment, waiver or other action becomes
effective, pursuant to Section 9.1 or Section 9.2, as the case
may be, it shall bind every Holder of a Security.

SECTION 9.5.  Notation on or Exchange of Securities.
          If an amendment, supplement or waiver changes the terms
of a Security, the Trustee may request the Holder of the Security
to deliver it to the Trustee.  The Trustee may place an
appropriate notation on the Security about the changed terms and
return it to the Holder.  Alternatively, if the Company or the
Trustee so determine, the Company in exchange for the Security
shall issue and the Trustee shall authenticate a new Security
that reflects the changed terms the cost and expense of which
will be borne by the Company.

SECTION 9.6.  Trustee to Sign Amendments, etc.
          The Trustee need not sign any amendment that adversely
affects its rights or interests, as determined by the Trustee in
its sole discretion.  In signing or refusing to sign any
amendment the Trustee shall be entitled to receive and shall be
fully protected in relying upon, an Opinion of Counsel stating
that such amendment is authorized or permitted by this Indenture.
The Company may not sign an amendment until its Board of
Directors approves it.


                           ARTICLE X.
                    CONVERSION OF SECURITIES
                                
SECTION 10.1.  Right of Conversion; Conversion Price.
          Subject to the provisions of Paragraph 8 of the
Securities, the Holder of any Security or Securities shall have
the right, at such Holder's option, at any time after the
effective date of the Registration Statement and before the close
of business on April 1, 2004 (except that, with respect to any
Security or portion of a Security which shall be called for
redemption, such right shall terminate at the close of business
on the Redemption Date fixed for redemption of such Security or
portion of a Security unless the Company shall default in payment
due upon redemption thereof), to convert, subject to the terms
and provisions of this Article 10, the principal of any such
Security or Securities or any portion thereof which is $1,000
principal amount or an integral multiple thereof into shares of
common stock of the Company, $.02 par value per share ("Common
Stock"), initially at the conversion price per share of $9.50 or,
in case an adjustment of such price has taken place pursuant to
the provisions of Section 10.4, then at the price as last
adjusted (such price or adjusted price being referred to herein
as the "conversion price"), upon surrender of the Security or
Securities, the principal of which is so to be converted,
accompanied by written notice of conversion duly executed, to the
Company, at any time during usual business hours at the office or
agency maintained by it for such purpose, and, if so required by
the Conversion Agent or Registrar, accompanied by a written
instrument or instruments of transfer in form satisfactory to the
Conversion Agent or Registrar duly executed by the Holder or his
duly authorized representative in writing.  For convenience, the
conversion of any portion of the principal of any Security or
Securities into shares of Common Stock is hereinafter sometimes
referred to as the conversion of such Security or Securities.

SECTION 10.2.  Issuance of Shares on Conversion.
          As promptly as practicable after the surrender, as
herein provided, of any Security or Securities for conversion,
the Company shall deliver or cause to be delivered at its said
office or agency, to or upon the written order of the Holder of
the Security or Securities so surrendered, certificates
representing the number of fully paid and nonassessable shares of
Common Stock into which such Security or Securities may be
converted in accordance with the provisions of this Article 10.
Such conversion shall be deemed to have been made as of the close
of business on the date that such Security or Securities shall
have been surrendered for conversion by delivery thereof with a
written notice of conversion duly executed, so that the rights of
the Holder of such Security or Securities as a Securityholder
shall cease at such time and, subject to the following provisions
of this paragraph, the Person or Persons entitled to receive the
shares of Common Stock upon conversion of such Security or
Securities shall be treated for all purposes as having become the
record holder or holders of such shares of Common Stock at such
time and such conversion shall be at the conversion price in
effect at such time; provided, however, that no such surrender on
any date when the stock transfer books of the Company shall be
closed shall be effective to constitute the Person or Persons
entitled to receive the shares of Common Stock upon such
conversion as the record holder or holders of such shares of
Common Stock on such date, but such surrender shall be effective
to constitute the Person or Persons entitled to receive such
shares of Common Stock as the record holder or holders thereof
for all purposes at the close of business on the next succeeding
day on which such stock transfer books are open; and provided,
further, that in such event such conversion shall be at the
conversion price in effect on the date that such Security or
Securities shall have been surrendered for conversion by delivery
thereof, as if the stock transfer books of the Company had not
been closed.  The Company shall give or cause to be given to the
Trustee written notice whenever the stock transfer books of the
Company shall be closed.

          Upon Conversion of any Security which is converted in
part only, the Company shall execute and the Trustee shall
authenticate and deliver to or on the order of the Holder
thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in principal amount equal
to the unconverted portion of such Security.

SECTION 10.3.  No Adjustment for Interest or Dividends.
          No payment or adjustment in respect of interest on the
Securities or dividends on the shares of Common Stock shall be
made upon the conversion of any Security or Securities; provided,
however, that if a Security or any portion thereof shall be
converted subsequent to any Regular Record Date and on or prior
to the next succeeding Interest Payment Date, the interest
falling due on such Interest Payment Date shall be payable on
such Interest Payment Date notwithstanding such conversion, and
such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name such Security is
registered at the close of business on such Regular Record Date
and Securities surrendered for conversion during the period from
the close of business on any Regular Record Date to the opening
of business on the corresponding Interest Payment Date must be
accompanied by payment of an amount equal to the interest payable
on such Interest Payment Date.

SECTION 10.4.  Adjustment of Conversion Price.
          (1)  In case the Company shall pay or make a dividend
or other distribution on any class of Capital Stock of the
Company in shares of Common Stock, the conversion price in effect
at the opening of business on the day following the date fixed
for the determination of stockholders entitled to receive such
dividend or other distribution shall be reduced by multiplying
such conversion price by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding at the close
of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the
total number of shares constituting such dividend or other
distribution, such reduction to become effective immediately
after the opening of business on the day following the date fixed
for such determination.

          (2)  In case the Company shall issue rights or warrants
to all or substantially all holders of its shares of Common Stock
entitling them to subscribe for or purchase shares of Common
Stock (or securities convertible into or exchangeable for Common
Stock) at a price per share (or having a conversion or exchange
price per share) less than the current market price per share
(determined as provided in paragraph (6) of this Section 10.4) of
the shares of Common Stock on the date fixed for the
determination of stockholders entitled to receive such rights or
warrants, the conversion price in effect at the opening of
business on the day following the date fixed for such
determination shall be reduced by multiplying such conversion
price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on
the date fixed for such determination plus the number of shares
of Common Stock which the aggregate of the subscription price of
the total number of shares of Common Stock so offered for
subscription or purchase (or the aggregate conversion of exchange
price of the convertible or exchangeable securities so offered)
would purchase at such current market price and the denominator
shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination plus
the number of shares of Common Stock so offered for subscription
or purchase, such reduction to become effective immediately after
the opening of business on the day following the date fixed for
such determination.  In the event that all of the shares of
Common Stock subject to such rights or warrants have not been
issued when such rights or warrants expire, then the conversion
price shall promptly be readjusted to the conversion price which
would then be in effect had the adjustment upon the issuance of
such rights or warrants been made on the basis of the actual
number of shares of Common Stock issued upon the exercise of such
rights or warrants.  No adjustment will be required for rights to
purchase Common Stock pursuant to a Company plan for reinvestment
of dividends or interest, or for a change in the par value of the
Common Stock.  For the purposes of this paragraph (2), the number
of shares of Common Stock at any time outstanding shall not
include shares held in the treasury of the Company but shall
include shares issuable in respect of scrip certificates issued
in lieu of fractions of shares of Common Stock.  The Company will
not issue any rights or warrants in respect of shares of Common
Stock held in the treasury of the Company.

          (3)  In case the outstanding shares of Common Stock
shall be subdivided into a greater number of shares, the
conversion price in effect at the opening of business on the day
following the day upon which such subdivision becomes effective
shall be proportionately reduced, and, conversely, in case
outstanding shares of Common Stock shall each be combined into a
smaller number of shares, the conversion price in effect at the
opening of business on the day following the day upon which such
combination becomes effective shall be proportionately increased,
such reduction or increase, as the case may be, to become
effective immediately after the opening of business on the day
following the day upon which such subdivision or combination
becomes effective.

          (4)  In case the Company shall, by dividend or
otherwise, distribute to all or substantially all holders of
shares of Common Stock evidences of indebtedness or assets
(including securities, but excluding any (a) rights or warrants
referred to in paragraph (2) of this Section 10.4, (b) any
dividend or distribution not prohibited by Section 4.6 hereof and
(c) any dividend or distribution referred to in paragraph (1) of
this Section 10.4), the conversion price shall be adjusted so
that the same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the close of
business on the day fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the
numerator shall be the current market price per share (determined
as provided in paragraph (6) of this Section) of the shares of
Common Stock on the date fixed for such determination less the
then fair market value as determined by the Board of Directors of
the Company (whose determination shall be conclusive and
described in a resolution of the Board of Directors of the
Company filed with the Trustee) of the portion of the assets or
evidences of indebtedness so distributed allocable to one share
of Common Stock and the denominator shall be such current market
price per share of the shares of Common Stock, such adjustment to
become effective immediately prior to the opening of business on
the day following the date fixed for the determination of
stockholders entitled to receive such distribution.

          (5)  In case the shares of Common Stock shall be
changed into the same or a different number of shares of any
class or classes of stock, whether by capital reorganization,
reclassification, or otherwise (other than a subdivision or
combination of shares or a stock dividend described in paragraph
(1) or (3) of this Section 10.4, or a consolidation, merger or
sale of assets described in Section 10.10), then and in each such
event the Holders of Securities shall have the right thereafter
to convert such Securities into the kind and amount of shares of
stock and other securities and property receivable upon such
reorganization, reclassification or other change, by holders of
the number of shares of Common Stock into which such Securities
might have been converted immediately prior to such
reorganization, reclassification or change.

          (6)  In case the Company shall report income before
extraordinary item and accounting charge diluted earnings per
share of less than $0.80 for its fiscal year ending March 31,
2000, the conversion price, as of 8:00 a.m. EST, in effect on the
Business Day following the day on which the Company files its
Annual Report on Form 10-K with respect to such fiscal year shall
be $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 of this Section 10.4).

          (7)  For the purpose of any computation under
paragraphs (2) and (4) of this Section, the current market price
per share of Common Stock on any date shall be deemed to be the
average of the Closing Prices for the 15 consecutive Business
Days selected by the Company commencing not more than 30 and not
less than 20 Business Days before the date in question.

          (8)  No adjustment in the conversion price shall be
required unless such adjustment (plus any adjustments not
previously made by reason of this paragraph (8)) would require an
increase or decrease of at least 1% in such price; provided,
however, that any adjustments which by reason of this paragraph
(8) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.  All
calculations under this paragraph (8) shall be made to the
nearest cent.

          (9)  The Company may, but shall not be required to,
make such reductions in the conversion price, in addition to
those required by paragraph (1), (2), (3), (4), (5) and (6) of
this Section 10.4 as the Company's Board of Directors considers
to be advisable in order to avoid or diminish any income tax to
any holders of shares of Common Stock resulting from any dividend
or distribution of stock or issuance of rights or warrants to
purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reason.  The Company's
Board of Directors shall  have the power to resolve any ambiguity
or correct any error in the adjustments made pursuant to this
Section 10.4 and its actions in so doing shall be final and
conclusive.

          (10) The adjustments provided for in this Section 10.4
shall be made successively whenever any event listed above shall
occur.

SECTION 10.5.  Notice of Adjustment of Conversion Price.
          Whenever the conversion price for the Securities is
adjusted as herein provided:

               (1)  the Company shall compute the adjusted
          conversion price in accordance with Section 10.4 and
          shall prepare an Officers' Certificate setting forth
          the adjusted conversion price and showing in reasonable
          detail the facts upon which such adjustment is based
          and the computation thereof, and such certificate shall
          forthwith be filed at each office or agency maintained
          for the purpose of conversion of the Securities
          pursuant to Section 2.3 and with the Trustee; and
          
               (2)  a notice stating that the conversion price
          has been adjusted and setting forth the adjusted
          conversion price shall as soon as practicable be mailed
          by the Company to all Holders of the Securities at
          their last addresses as they shall appear in the
          Security Register.
          
               (3)  If the conversion price is adjusted and the
          Company fails to file an Officers' Certificate with the
          Trustee as provided by Section 10.5(1) and the Trustee
          is acting as the Conversion Agent, the Trustee shall be
          entitled to rely conclusively on the conversion price
          set forth in the Officer's Certificate most recently
          received by the Trustee (or as set forth in the
          Securities and this Indenture if the conversion price
          shall not have been adjusted).
          
SECTION 10.6.  Notice of Certain Corporate Action.
          (1)  In case:

               (a)  the Company shall authorize the granting to
          holders of its shares of Common Stock of rights or
          warrants entitling them to subscribe for or purchase
          any shares of Capital Stock of any class or of any
          other rights; or
          
               (b)  of any reclassification of the shares of
          Common Stock of the Company, or of any consolidation or
          merger to which the Company is a party and for which
          approval of any stockholders of the Company is
          required, or of the sale or transfer of all or
          substantially all of the assets of the Company; or
          
               (c)  of the voluntary or involuntary dissolution,
          liquidation or winding up of the Company;
          
then the Company shall cause to be filed at each office or agency
maintained for the purpose of conversion of the Securities
pursuant to Section 2.3 and shall cause to be mailed to the
Trustee and all Holders of the Securities at their last addresses
as they shall appear in the Security Register, at least 20 days
(or 10 days in any case specified in clause (a) or (b) above)
prior to the applicable record date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for
the purpose of such dividend, distribution, rights or warrants,
or, if a record is not to be taken, the date as of which the
Holders of shares of Common Stock of record to be entitled to
such dividend, distribution, rights or warrants are to be
determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation
or winding up is expected to become effective, and the date as of
which it is expected that holders of shares of Common Stock of
record shall be entitled to exchange their shares of Common Stock
for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.  Such notice shall also
state whether such transaction will result in any adjustment in
the conversion price applicable to the Securities and, if so,
shall state what the adjusted conversion price will be and when
it will become effective.  Neither the failure to give the notice
required by this Section, nor any defect therein, to any
particular Holder shall affect the sufficiency of the notice or
the legality or validity of any such dividend, distribution,
right, warrant, reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution or winding-up, or the vote on
any action authorizing such with respect to the other holders.

          (2)  In case the Company or any Affiliate of the
Company shall propose to engage in a "Rule 13e-3 Transaction" as
defined in the Commission's Rule 13e-3 under the Exchange Act,
the Company shall, no later than the date on which any
information with respect to such Rule 13e-3 Transaction is first
required to be given to the Commission or any other Person
pursuant to such Rule 13e-3, cause to be mailed to all Holders at
their last addresses as they shall appear in the Security
Register, a copy of all information required to be given to the
holders of the Company's Capital Stock pursuant to such Rule 13e-
3.  The information required to be given under this paragraph
shall be in addition to and not in lieu of any other information
required to be given by the Company pursuant to this Section 10.6
or any other provision of the Securities or this Indenture.

SECTION 10.7.  Taxes on Conversions.
          The Company will pay any and all stamp or similar taxes
that may be payable in respect of the issuance or delivery of
shares of Common Stock on conversion of the Securities pursuant
hereto.  The Company shall not, however, be required to pay any
tax which may be payable in respect of any transfer involved in
the issuance and delivery of shares of Common Stock in a name
other than that of the Holder of the Security or Securities to be
converted, and no such issuance or delivery shall be made unless
and until the Person requesting such issuance has paid to the
Company the amount of any such tax, or has established to the
satisfaction of the Company that such tax has been paid.

SECTION 10.8.  Fractional Shares.
          No fractional shares or scrip representing fractional
shares shall be issued upon any conversion of the Securities.  If
any such conversion would otherwise require the issuance of a
fractional share an amount equal to such fraction multiplied by
the current market price per share of Common Stock (determined as
provided in paragraph (6) of Section 10.4) on the day of
conversion shall be paid to the Holder in cash by the Company.

SECTION 10.9.  Cancellation of Converted Securities.
          All Securities delivered for conversion shall be
delivered to the Trustee or the Conversion Agent to be canceled
by or at the direction of the Trustee or the Conversion Agent,
which shall dispose of the same as provided in Section 2.9.

SECTION 10.10.  Provisions in Case of Consolidation, Merger or
Sale of Assets.
          (1)  In case of any consolidation of the Company with,
or merger of the Company into, any Person, or in case of any
merger of another Person into the Company (other than a
consolidation or merger which does not result in any
reclassification, conversion, exchange or cancellation of
outstanding shares of Common Stock), or in case of any sale or
transfer of all or substantially all of the assets of the
Company, the Person formed by such consolidation or resulting
from such merger or which acquires such assets, as the case may
be, shall execute and deliver to the Trustee a supplemental
indenture providing that the Holder of each Security then
outstanding shall have the right thereafter, during the period
such Security shall be convertible as specified in Section 10.1
to convert such Security only into the kind and amount of
securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number
of shares of Common Stock into which such Security might have
been converted immediately prior to such consolidation, merger,
sale or transfer.  Such supplemental indenture shall provide for
adjustments which, for events subsequent to the effective date of
such supplemental indenture, shall be as nearly equivalent as may
be practicable to the adjustments provided for in this Article
10.  The above provisions of this Section 10.10 shall similarly
apply to successive consolidations, mergers, sales or transfers.

          (2)  The Trustee shall not be under any responsibility
to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount
of shares of stock or securities or property receivable by
Holders upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale or
conveyance or to any adjustment to be made with respect thereto.

SECTION 10.11.  Disclaimer by Trustee of Responsibility for
Certain Matters.
          The Trustee and each Conversion Agent (other than the
Company or any Subsidiary) shall not at any time be under any
duty or responsibility to any Holder of the Securities to
determine whether any facts exist which may require any
adjustment of the conversion price, how it should be calculated
or what it should be, or with respect to the nature or extent of
any such adjustment when made, or with respect to the method
employed, or herein or in any supplemental indenture provided to
be employed, in making the same.  The Trustee and each Conversion
Agent (other than the Company or any Subsidiary) shall not be
accountable with respect to the validity, value, kind or amount
of any shares of Common Stock, or of any securities or property,
which may at any time be issued or delivered upon the conversion
of any Security; and it makes no representation with respect
thereto.  The Trustee and each Conversion Agent (other than the
Company or any Subsidiary) shall not be responsible for any
failure of the Company to issue, transfer or deliver any shares
of Common Stock or stock certificates or other securities or
property upon the surrender of any Security for the purpose of
conversion or, subject to Section 7.1, to comply with any of the
covenants of the Company contained in this Article 10.

SECTION 10.12.  Covenant to Reserve Shares.
          The Company covenants that it will at all times reserve
and keep available, free from preemptive rights, out of its
authorized shares of Common Stock, solely for the purpose of
issuance upon conversion of the Securities as herein provided,
such number of shares of Common Stock as shall then be issuable
upon the conversion of all outstanding Securities.  The Company
covenants that all shares of Common Stock which shall be so
issuable shall be, when issued, duly and validly issued and fully
paid and non-assessable.  For purposes of this Section 10.12, the
number of shares of Common Stock which shall be deliverable upon
the conversion of all outstanding Securities shall be computed as
if at the time of computation all outstanding Securities were
held by a single holder.

                           ARTICLE XI.
                    SUBORDINATION; SENIORITY
                                
SECTION 11.1.  Securities Subordinated to Senior Indebtedness.
          (1)  The Company agrees, and each Holder of the
Securities by his acceptance thereof likewise agrees, that the
payment of the principal of, premium, if any, and interest on the
Securities (all of the foregoing, a "Payment or Distribution") is
subordinated and junior in right of payment, to the extent and in
the manner provided in this Article 11, except as provided in
Article 8, to the prior payment in full in cash of all Senior
Indebtedness whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed.

          A Payment or Distribution shall include any asset of
any kind or character, and may consist of cash, securities or
other property, by set-off or otherwise, and shall include,
without limitation, any purchase, redemption or other acquisition
of Securities or the making of any deposit of funds or securities
pursuant to this Indenture (including, without limitation, any
deposit pursuant to Article 8 hereof).

          (2)  The Senior Indebtedness of the Company shall
continue to be Senior Indebtedness and entitled to the benefit of
these subordination provisions irrespective of any amendment,
modification or waiver of any term of any instrument relating to
refinancing of the Senior Indebtedness.

          (3)  All the provisions of this Indenture and the
Securities shall be subject to the provisions of this Article 11
so far as they may be applicable thereto, except that nothing in
this Article 11 shall apply to claims for, or payments to, the
Trustee under or pursuant to Section 7.7.

          (4)  No right of any holder of any Senior Indebtedness
to enforce subordination as herein provided shall at any time or
in any way be affected or impaired by any failure to act on the
part of the Company, any Paying Agent, the Holders of the
Securities, the Trustee or the holders of the Senior
Indebtedness, or by any noncompliance by the Company, any Paying
Agent, the Holders of the Securities or the Trustee with any of
the terms, provisions and covenants of the Securities or this
Indenture, regardless of any knowledge thereof that any such
holder of Senior Indebtedness may have or be otherwise charged
with.

SECTION 11.2.  Company Not to Make Payments with Respect to
Securities in Certain Circumstances.
          No Payment or Distribution shall be made by the
Company, the Trustee or any Paying Agent on account of principal
of, premium, if any, or interest on the Securities, whether upon
stated maturity, upon redemption or acceleration, or otherwise,
or on account of the purchase or other acquisition of Securities,
whether upon stated maturity, upon redemption or acceleration, or
otherwise, if there shall have occurred and be continuing a
default with respect to any Senior Indebtedness permitting the
acceleration thereof or with respect to the payment of any Senior
Indebtedness and (a) such default is the subject of a judicial
proceeding or (b) written notice of such default has been given
to the Company by any holder or holders of any 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
Securities or any payment by the Company or distribution of
assets of the Company of any kind or character, whether in cash,
property or securities, to creditors upon any dissolution or
winding up or liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become
due upon all Senior Indebtedness shall first be paid in full in
cash, or payment thereof provided for to the satisfaction of the
holders thereof, before any Payment or Distribution is made on
account of the redemption price or principal of (and premium, if
any) or interest on the Securities; and (subject to the power of
a court of competent jurisdiction to make other equitable
provision, which shall have been determined by such court to give
effect to the rights conferred in this Article upon the Senior
Indebtedness and the holders thereof with respect to the
Securities or the Holders thereof or the Trustee, by a lawful
plan of reorganization or readjustment under applicable law) upon
any such dissolution or winding up or liquidation or
reorganization, any Payment or Distribution by the Company or
distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than securities of
the Company as reorganized or readjusted or securities of the
Company or any other company, trust or corporation provided for
by a plan of reorganization or readjustment, the payment of which
is junior or otherwise subordinate,  at least to the extent
provided in this Article 11 with respect to the Securities to the
payment of all Senior Indebtedness at the time outstanding and to
the payment of all securities issued in exchange therefor to the
holders of the Senior Indebtedness at the time outstanding, and
the rights of the holders of Senior Indebtedness of the Company
are not altered by such plan of reorganization or readjustment),
to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article 11, shall be
paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such Payment or
Distribution directly to the holders of Senior Indebtedness of
the Company or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any
instruments evidencing any Senior Indebtedness may have been
issued, as their respective interests may appear, to the extent
necessary to pay all Senior Indebtedness in full in cash, after
giving effect to any concurrent payment or distribution to or for
the holders of Senior Indebtedness, before any Payment or
Distribution is made to the Holders of the Securities or to the
Trustee, except that the Trustee will have a lien for the payment
of its fees and expenses.

          In the event that, notwithstanding the foregoing, any
Payment or Distribution by the Company of any kind or character,
(whether such payment shall be in cash, property or securities)
which is prohibited by the foregoing, shall have been made to the
Trustee or the Holders of the Securities before all Senior
Indebtedness is paid in full in cash, or provision is made for
such payment to the satisfaction of the holders thereof, and if
such fact shall then have been or thereafter be made known to a
Trust Officer of the Trustee or, as the case may be, such Holder,
then and in such event such Payment or Distribution shall be paid
over by the Trustee (if the Notice required by Section 11.5 has
been timely received by the Trustee) or such Holder or delivered
to the holders of Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior
Indebtedness may have been issued, as their respective interests
may appear, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all
Senior Indebtedness in full in cash, after giving effect to any
concurrent Payment or Distribution to or for the holders of such
Senior Indebtedness, and, until so delivered, the same shall be
held in trust by any Holder of a Security as the property of the
holders of Senior Indebtedness.

          The consolidation of the Company with, or the merger of
the Company into, another Person or the liquidation or
dissolution of the Company following the conveyance or transfer
of its property as an entirety, or substantially as an entirety,
to another corporation upon the terms and conditions provided in
Article 5 shall not be deemed a dissolution, winding up,
liquidation or reorganization for the purposes of this Section
11.2 if such other Person shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated
in Article 5.  Nothing in this Section shall apply to claims of,
or payments to, the Trustee under or pursuant to Section 7.7.

          The holders of Senior Indebtedness may, at any time and
from time to time, without the consent of or notice to the
Holders of the Securities, without incurring responsibility to
the Holders of the Securities and without impairing or releasing
the obligations of the Holders of the Securities hereunder to the
holders of Senior Indebtedness: (i) change the manner, place or
terms of payment or change or extend the time of payment of, or
renew or alter, Senior Indebtedness, or otherwise amend in any
manner Senior Indebtedness or any instrument evidencing the same
or any agreement under which Senior Indebtedness is outstanding;
(ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness;
(iii) release any Person liable in any manner for the collection
of Senior Indebtedness; (iv) apply any amounts received to any
liability (other than Subordinated Indebtedness) of the Company
owing to holders of Senior Indebtedness; and/or (v) exercise or
refrain from exercising any rights against the Company and any
other Person.

SECTION 11.3.  Subrogation of Securities.
          Subject to the payment in full in cash of all amounts
then due (whether by acceleration of the maturity thereof or
otherwise) on account of all Senior Indebtedness at the time
outstanding, the Holders of the Securities shall be subrogated to
the rights of the holders of Senior Indebtedness to receive
Payments or Distributions of cash, property or securities of the
Company applicable to the Senior Indebtedness until the principal
of, premium, if any, and interest on the Securities shall be paid
in full; and, for the purposes of such subrogation, no Payments
or Distributions to the holders of Senior Indebtedness to which
the Holders of the Securities or the Trustee would be entitled
except for the provisions of this Article 11, and no payments
over pursuant to the provisions of this Article 11 to the holders
of Senior Indebtedness by Holders of the Securities or the
Trustee, shall, as between the Company, the Company's creditors
other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness.  It is understood that the
provisions of this Article 11 are and are intended solely for the
purpose of defining the relative rights of the Holders of the
Securities, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

          Nothing contained in this Article 11 or elsewhere in
this Indenture or in the Securities is intended to or shall
impair, as among the Company, its creditors other than the
holders of Senior Indebtedness, and the Holders of the
Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the
principal of, premium, if any, and interest on the Securities as
and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative
rights of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the
rights, if any, under this Article 11 of the holders of Senior
Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.  Nothing
in this Article 11 shall prevent conversions of Securities
pursuant to Article 10.

          Upon any payment or distribution of assets of the
Company referred to in this Article 11, the Trustee, subject to
the provisions of Section 7.1, and the Holders of the Securities
shall be entitled to rely upon any order or decree made by any
court of competent jurisdiction in which any dissolution, winding
up, liquidation or reorganization proceedings are pending, or
certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the
Securities, for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to
this Article 11.
          
SECTION 11.4.  Authorization by Holders of Securities.
          Each holder of a Security by his acceptance thereof
authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate, as
between the Holder of the Security and the holders of Senior
Indebtedness, the subordination provided in this Article 11 and
appoints the Trustee his attorney-in-fact for any and all such
purposes including, without limitation, to execute, verify,
deliver and file any proofs of claim which any holder of Senior
Indebtedness may at any time require in order to prove and
realize upon any rights or claims pertaining to the Securities
and to effectuate the full benefit of the subordination contained
herein.  If the Trustee shall fail to do so prior to 30 days
prior to the expiration of the period for filing such claims, any
such holder of Senior Indebtedness shall be deemed to be
irrevocably appointed the agent and attorney-in-fact of the
Holder to execute, verify, deliver and file any such proofs of
claim; provided that no holder of Senior Indebtedness shall incur
any liability for any failure to exercise its right to file any
such proofs of claim.

SECTION 11.5.  Notices to Trustee.
          The Company shall give prompt written notice to the
Trustee of any fact known to it which would prohibit the making
of any payment of moneys to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article 11.
Notwithstanding the provisions of this Article 11 or any other
provision of this Indenture, the Trustee shall not be charged
with knowledge of the existence of any facts which would prohibit
the making of any payment of moneys to or by the Trustee in
respect of the Securities pursuant to the provisions of this
Article 11 unless and until a Trust Officer of the Trustee shall
have received at its Corporate Trust Office written notice
thereof from the Company or a holder or holders of Senior
Indebtedness or from any trustee or agent therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to
the provisions of Section 7.1, shall be entitled in all respects
to assume that no such facts exist; provided, however, that if a
Trust Officer of the Trustee shall not have received at least
three Business Days prior to the date upon which by the terms
hereof any such moneys may become payable for any purpose
(including, without limitation, the payment of the principal of,
premium, if any, or interest on any Security) with respect to
such moneys the notice provided for in this Section 11.5, then,
anything herein contained to the contrary notwithstanding, the
Trustee shall have the full power and authority to receive such
moneys and to apply the same to the purpose for which they were
received and shall not be affected by any notice to the contrary
which may be received by it within three Business Days prior to
such date or at any time thereafter.

          The Trustee shall be entitled to rely conclusively on
the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such notice has been
given by a holder of Senior Indebtedness or a trustee or agent on
behalf of any such holder.  In the event that the Trustee
determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Indebtedness held by such Person, the
extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the
rights of such Person under this Article 11, and if such evidence
is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such
Person to receive such payment.

SECTION 11.6.  Trustee's Relation to Senior Indebtedness.
          The Trustee in its individual capacity shall be
entitled to all the rights set forth in this Article 11 in
respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness, and
nothing in Section 7.11 or elsewhere in this Indenture shall
deprive the Trustee of any of its rights as such holder.

          With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this
Article 11, and no implied covenants or obligations with respect
to the holders of Senior Indebtedness shall be read into this
Indenture against the Trustee.  The Trustee shall not owe any
fiduciary duty to the holders of Senior Indebtedness and shall
not be liable to any such holder if it shall mistakenly pay over
or distribute to Holders of the Securities or the Company or any
other Person money or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article 11 or
otherwise.

SECTION 11.7.  No Impairment of Subordination.
          No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at
any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company, the Trustee or the
Holder of any of the Securities or by any act, or failure to act,
in good faith, by any such holder of Senior Indebtedness, or by
any noncompliance by the Company, the Trustee or the Holder of
any of the Securities with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof which any
such holder may have or otherwise be charged with.

SECTION 11.8.  Article 11 Not To Prevent Events of Default.
          The failure to make a payment on account of principal
of, premium, if any, or interest on the Securities by reason of
any provision in this Article 11 shall not be construed as
preventing the occurrence of an Event of Default with respect to
such Securities under Section 6.1.

SECTION 11.9.  Paying Agents other than the Trustee.
          In any case at any time any Paying Agent other than the
Trustee shall have been appointed by the Company and be then
acting hereunder, the term "Trustee" as used in this Article 11
shall in such case (unless the context shall otherwise require)
be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if
such Paying Agent were named in this Article 11 in addition to or
in place of the Trustee.

SECTION 11.10.  Securities Senior to Subordinated Indebtedness.
          The indebtedness represented by the Securities will be
senior and prior in right of payment to all Subordinated
Indebtedness, to the extent and in the manner provided in such
Subordinated Indebtedness.

                          ARTICLE XII.
                   RIGHT TO REQUIRE REPURCHASE
                                
SECTION 12.1  Right to Require Repurchase.
          In the event that there shall occur a Change in Control
(as defined in Section 12.5), each Holder shall have the right,
at such Holder's option, to require the Company to purchase, and
upon the exercise of such right, the Company shall, subject to
the provisions of Article XI, purchase, all or any part of such
Holder's Notes on the date (the "Repurchase Date") that is 75
days after the date the Company gives notice of the Change in
Control as contemplated in Section 12.2(1) at a price (the
"Repurchase Price") equal to 101% of the principal amount
thereof, together with accrued and unpaid interest to the
Repurchase Date. In connection with the exercise of the
repurchase right by a Holder prior to a Redemption Date, a
Holder's right to exercise his repurchase right shall terminate
at the close of business on the Business Day prior to the
Redemption Date.
          
SECTION 12.2.  Notice; Method of Exercising Repurchase Right.
          (1)  On or before the 15th day after the occurrence of
a Change in Control, the Company or, at the request of the
Company, the Trustee (in the name and at the expense of the
Company), shall give notice of the occurrence of the Change in
Control and of the repurchase right set forth herein arising as a
result thereof by first-class mail, postage prepaid, to each
Holder of the Notes at such Holder's address appearing in the
Note Register. The Company shall also deliver a copy of such
notice of a repurchase right to the Trustee.

               Each notice of a repurchase right shall state:

               (a)  the event constituting the Change in Control
and the date thereof;

               (b)  the Repurchase Date;

               (c)  the date by which the repurchase right must
be exercised;

               (d)  the Repurchase Price; and

               (e)  the procedures a Holder must follow to
exercise a repurchase right.

          No failure of the Company to give the foregoing notice
shall limit any Holder's right to exercise a repurchase right.
The Trustee shall have no affirmative obligation to determine if
there shall have occurred a Change in Control.

          (2)  To exercise a repurchase right, a Holder shall
deliver to the Company (or an agent designated by the Company for
such purpose in the notice referred to in (1) above) and to the
Trustee on or before the tenth day prior to the Repurchase Date
(a) written notice of the Holder's exercise of such right, which
notice shall set forth the name of the Holder, the principal
amount of the Note or Notes (or portion of a Note) to be
repurchased and a statement that an election to exercise the
repurchase right is being made thereby and (b) the Note or Notes
with respect to which the repurchase right is being exercised,
duly endorsed for transfer to the Company. Such written notice
shall be irrevocable. If the Repurchase Date falls between any
Regular Record Date and the next succeeding Interest Payment
Date, Notes to be repurchased must be accompanied by payment from
the Holder of an amount equal to the interest thereon which the
registered Holder thereof is to receive on such Interest Payment
Date. A Holder that fails to exercise a repurchase right in
accordance with the terms hereof shall waive such repurchase
right but the rights of such Holder to receive principal of and
interest on the Notes and all other rights of such Holder under
this Indenture shall not be affected thereby.

          (3)  In the event a repurchase right shall be exercised
in accordance with the terms hereof, the Company shall on the
Repurchase Date pay or cause to be paid in cash to the Holder
thereof the Repurchase Price of the Note or Notes as to which the
repurchase right has been exercised. In the event that a
repurchase right is exercised with respect to less than the
entire principal amount of a surrendered Note, the Company shall
execute and deliver to the Trustee and the Trustee shall
authenticate for issuance in the name of the Holder a new Note or
Notes in the aggregate principal amount of the unrepurchased
portion of such surrendered Note.

SECTION 12.3.  Deposit Of Repurchase Price.
          On or prior to the Repurchase Date, the Company shall
deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 2.4) an amount (in immediately
available funds) of money sufficient to pay the Repurchase Price
of the Notes which are to be repaid on the Repurchase Date.

SECTION 12.4.  Notes Not Repurchased On Repurchase Date.
          If any Note surrendered for repurchase shall not be so
paid on the Repurchase Date, the principal shall, until paid,
bear interest to the extent permitted by applicable law from the
Repurchase Date at the rate per annum borne by such Note.

          SECTION 12.5.  "Change In Control" Defined.

          For purposes of this Article, "Change In Control" means
any of the following events that occur after the date of this
Indenture and on or prior to Maturity:

          (1)  all or substantially all of the Company'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 the Company (a) in which the Company is not the
continuing or surviving corporation (other than a consolidation
or merger with a wholly-owned subsidiary of the Company in which
all Common Stock outstanding immediately prior to the
effectiveness thereof are changed into or exchanged for the same
consideration) or (b) pursuant to which the Common Stock are
converted into cash, securities or other property, in each case
other than a consolidation or merger of the Company 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 shares of the continuing or surviving
corporation immediately after such consolidation or merger; or

          (3)  any person, or any persons acting together which
would constitute a "group" for purposes of Section 13(d) of the
Securities Exchange Act of 1934 (a "Group"), together with any
Affiliates thereof, shall acquire beneficial ownership (as
defined in Rule 13d-3 under the Securities Exchange Act of 1934)
of at least 50% of the total voting power of all classes of
capital shares of the Company entitled to vote generally in the
election of directors of the Company.

          Notwithstanding anything to the contrary set forth in
this definition, a Change in Control shall not be deemed to have
occurred:

          (A)  under paragraph (3) above, solely by virtue of the
Company, 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 the Company or any Subsidiary or any Person
holding securities of the Company 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
Securities Exchange Act of 1934 disclosing beneficial ownership
by it of shares or securities of the Company, whether at least
50% of the total voting power referred to in paragraph (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; or

          (B)  under paragraphs (1), (2) or (3) above if:

               (i)  the Current Market Price of the Common Stock
on the date the Change in Control shall have occurred is at least
equal to 105% of the Conversion Price in effect immediately
preceding the time of such Change in Control; or

               (ii) 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
common shares 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 Notes
become convertible solely into such common shares; or

               (iii)     the consideration in the transaction
giving rise to such Change in Control to the holders of Common
Stock consists of cash, securities that are, or immediately upon
issuance will be, listed on a national securities exchange or
quoted on the Nasdaq National Market, or a combination of cash
and such securities, and the aggregate fair market value of such
consideration (which, in the case of such securities, shall be
equal to the average of the daily Closing Prices of such
securities during the ten consecutive Trading Days commencing
with the sixth Trading Day following consummation of such
transaction) is at least 105% of the Conversion Price in effect
on the date immediately preceding the closing date of such
transaction.

          If a Change in Control shall have occurred under
paragraph (2) above, the Company shall deliver the Officers'
Certificate and Opinion of Counsel called for under Section 13.4
as well as the notices called for under Section 10.5.

          For purposes of this definition of Change of Control,
"Current Market Price" on any date means the average daily
Closing Prices for the five consecutive Trading Days selected by
the Company commencing not more than ten Trading Days before, and
ending not later than, the date in question; "Closing Price" for
any Trading Day means the last reported sale price (or, if none
on any day, the mean between the bid and asked quotations on such
day) of the securities in question for such date, in either case
on the New York Stock Exchange or, if the securities are not
listed or admitted to trading on such exchange, on the principal
national securities exchange on which such securities are listed
or admitted to trading or, if not listed or admitted to trading
on any national securities exchange, on The Nasdaq National
Market or, if the securities are not listed or admitted to
trading on any national securities exchange or quoted on the
Nasdaq National Market, the average of the closing bid and asked
prices in the over-the-counter market as furnished by any New
York Stock Exchange member firm selected by the Company for such
purpose; and "Trading Day", with respect to any stock exchange or
securities market, means any Monday, Tuesday, Wednesday, Thursday
or Friday on which such stock exchange or securities market is
open for business.

Holder shall have no claim therefor against any party hereto.

                     COMPTEK RESEARCH, INC.
       8-1/2% Convertible Subordinated Debenture Due 2004
                                
         1.   Interest.  Comptek Research, Inc., a New York
corporation (the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown
above.  The Company will pay interest semiannually on April 1 and
October 1 of each year beginning October 1, 1999.  Interest on
the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from
March 24, 1999; provided that, if there is no existing Default in
the payment of interest, and if this Security is authenticated
between a record date referred to on the face hereof and the next
succeeding interest payment date, interest shall accrue from such
interest payment date.  Interest will be computed on the basis of
a 360 day year of twelve 30-day months.

         2.   Method of Payment.  The Company will pay interest
on the Securities (except defaulted interest) to the persons who
are the registered Holders of the Securities at the close of
business on the September 15 or March 15 immediately preceding
the interest payment date.  Holders must surrender Securities to
a Paying Agent to collect principal and premium payments.  The
Company will pay principal, premium and interest in money of the
United States that at the time of payment is legal tender for
payment of public and private debts.  The Company, however, may
pay principal, premium and interest by its check payable in such
money.  It may mail an interest check to a Holder's registered
address.

         The payment of principal of and premium, if any, on this
Security shall be payable only upon surrender of this Security at
the office or agency of the Paying Agent in the Borough of
Manhattan, City and State of New York.  Payments of principal of,
premium, if any, and interest on this Security shall be made at
the office or agency of the Trustee maintained in the Borough of
Manhattan, City and State of New York, or, in the case of any
such payments other than the payment of principal and premium, if
any, at the Company's option, by check mailed to the Person
entitled thereto at such Person's address last appearing on the
Company's register.

         3.   Registrar and Agents.  Initially, The Bank of New
York will act as Registrar, Paying Agent, Conversion Agent and
agent for service of notices and demands.  The Company may change
any Registrar, co-registrar, Paying Agent, Conversion Agent and
agent for service of notices and demands without notice.  The
Company or any of its Subsidiaries may act as Paying Agent or
Conversion Agent.  The address of The Bank of New York is 101
Barclay Street, New York, New York 10286.

         4.   Indenture; Limitations.  The Company issued the
Securities under an Indenture, dated as of March 24, 1999 (the
"Indenture"), between the Company and The Bank of New York, as
trustee (the "Trustee").  Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein.  The
terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code  77aaa-77bbbb) as in effect
on the date of the Indenture.  The Securities are subject to all
such terms, and the Holders of the Securities are referred to the
Indenture and said Act for a statement of them.

         The Securities are general unsecured obligations of the
Company limited to $20,000,000 principal amount.  The Indenture
imposes certain limitations on the ability of the Company to,
among other things, make payments in respect of its Capital
Stock, merge or consolidate with any other Person and sell,
lease, transfer or otherwise dispose of its properties or assets.

         5.   Optional Redemption by the Company.  The Company
may, at its option, at any time on or after March 1, 2002, redeem
all of the Debentures or some of them, on at least 30 days' but
not more than 60 days' written notice to each holder of
Debentures to be redeemed at his or her registered address, at
the redemption prices set forth below.  The redemption prices
(expressed 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%
                                      
The Debentures may not be so redeemed before March 1, 2002.

          6.  Certain Rights to Require Repurchase of Debentures
by the Company.  In the event that there shall occur a Change in
Control of the Company, each Holder shall have the right, at such
Holder's option, to require the Company to purchase, all or any
part of such Holder's Notes, 75 days after the date the Company
gives notice of the Change in Control as contemplated in the
Indenture, at a price equal to 101% of the principal amount
thereof, together with accrued and unpaid interest.

          7.  Notice of Redemption.  Notice of redemption will be
mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of Securities to be redeemed at
his registered address.  Securities in denominations larger than
$1,000 principal amount may be redeemed in part, but only in
whole multiples thereof.  On and after the Redemption Date
interest ceases to accrue on Securities or portions of them
called for redemption.

         8.   Conversion.  A Holder of a Security may convert
such Security into shares of common stock of the Company after
the effective date of the Registration Statement and before the
close of business on April 1, 2004.  If the Security is called
for redemption, the Holder may convert it at any time before the
close of business on the date fixed for such redemption.  The
initial conversion price is $9.50 per share, subject to
adjustment in certain events.  To determine the number of shares
issuable upon conversion of a Security, divide the principal
amount to be converted by the conversion price in effect on the
conversion date.  The Company will deliver a check for any
fractional share.

          To convert a Security, a Holder must (1) complete and
sign the conversion notice on the back of the Security,
(2) surrender the Security to the Conversion Agent, (3) furnish
appropriate endorsements and transfer documents if required by
the Registrar or Conversion Agent and (4) pay any transfer or
similar tax if required.  No payment or adjustment is to be made
on conversion for interest accrued hereon or for dividends on
shares of common stock issued on conversion; provided, however,
that if a Security is surrendered for conversion after the record
date for a payment of interest and on or before the interest
payment date, then, notwithstanding such conversion, the interest
falling due to such interest payment date will be paid to the
Person in whose name the Security is registered at the close of
business on such record date and any Security surrendered for
conversion during the period from the close of business on any
regular record date to the opening of business on the
corresponding interest payment date must be accompanied by
payment of an amount equal to the interest payable on such
interest payment date.  A Holder may convert a portion of a
Security if the portion is $1,000 principal amount or an integral
multiple thereof.

          If the Company is a party to a consolidation or merger
or a transfer or lease of all or substantially all of its assets,
the right to convert a Security into shares of common stock may
be changed into a right to convert it into securities, cash or
other assets of the Company or another Person.

          9.  Subordination.  This Security is subordinated to
all Senior Indebtedness of the Company.  To the extent and in the
manner provided in the Indenture, Senior Indebtedness must be
paid before any payment may be made to any Holders of Securities.
Any Securityholder by accepting this Security agrees to such
subordination and authorizes the Trustee to give it effect.

          In addition to all other rights of Senior Indebtedness
described in the Indenture, the Senior Indebtedness shall
continue to be Senior Indebtedness and entitled to the benefits
of the subordination provisions irrespective of any amendment,
modification or waiver of any term of any instrument relating to
the Senior Indebtedness or extension or renewal of the Senior
Indebtedness.

          10. Denominations, Transfer, Exchange.  The Securities
issued under the Indenture are in the aggregate principal amount
of up to $20,000,000.  The Securities are in registered form
without coupons in denominations of $1,000 principal amount and
integral multiples thereof.  A Holder may register the transfer
of or exchange Securities in accordance with the Indenture.  The
Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any
taxes and fees required by law or permitted by the Indenture.
The Registrar need not register the transfer of or exchange any
Securities selected for redemption or register the transfer of or
exchange any Securities for a period of 15 days before a
selection of Securities to be redeemed.

          11. Persons Deemed Owners.  The registered Holder of a
Security may be treated as its owner for all purposes.

          12. Unclaimed Money.  If money for the payment of
principal or interest on any Securities remains unclaimed for two
years, the Trustee and the Paying Agent will pay the money back
to the Company at its written request.  After that, Holders may
look only to the Company for payment.

          13. Discharge Prior to Redemption or Maturity.  The
Indenture will be discharged and canceled except for certain
sections thereof upon payment of all the Securities, or upon the
irrevocable deposit with the Trustee of funds or U.S. Government
Obligations maturing on or before such payment date or Redemption
Date, sufficient to pay principal, premium, if any, and interest
on such payment or redemption.

          14. Amendment and Waiver.  Subject to certain
exceptions, without notice to the Holders of the Securities, the
Indenture or the Securities may be amended with the consent of
the Holders of at least 66-2/3% in principal amount of the
Securities then outstanding and any existing default or
compliance with any provision may be waived with the consent of
the Holders of a majority in principal amount of the Securities
then outstanding.  Without the consent of or notice to any
Securityholder, the Company may amend or supplement the Indenture
or the Securities to, among other things, provide for
uncertificated Securities, to cure any ambiguity, defect or
inconsistency or make any other change that does not adversely
affect the rights of any Securityholder.

          15. Successors.  When a successor assumes all the
obligations of its predecessor under the Securities and the
Indenture, the predecessor will be released from those
obligations.

          16. Defaults and Remedies.  If an Event of Default, as
defined in the Indenture (other than a Event of Default relating
to bankruptcy of the Company), occurs and is continuing, the
Trustee or the Holders of a majority in principal amount of
Securities may declare all the Securities to be due and payable
immediately in the manner and with the effect provided in the
Indenture.  If an Event of Default relating to bankruptcy of the
Company occurs, then all Securities shall become immediately due
and payable without any declaration or act on the part of the
Trustee or any Holder.  Holders of Securities may not enforce the
Indenture or the Securities except as provided in the Indenture.
The Trustee may require indemnity satisfactory to it, subject to
the provisions of the TIA, before it enforces the Indenture or
the Securities.  Subject to certain limitations, Holders of a
majority in principal amount of the Securities then outstanding
may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of Securities notice of any
continuing default (except a default in payment of principal or
interest) if it determines that withholding notice is in their
interests.  The Company is required to file periodic reports with
the Trustee as to the absence of any Default or Event of Default.

          17. Trustee Dealings with the Company.  The Bank of New
York, the Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may
otherwise deal with the Company or its Affiliates, as if it were
not Trustee.

          18. No Recourse Against Others.  No stockholder,
director, officer or incorporator, as such, past, present or
future, of the Company or any successor corporation shall have
any liability for any obligation of the Company under the
Securities or the Indenture or for any claim based on, in respect
of or by reason of, such obligations or their creation.  Each
Holder of a Security by accepting a Security waives and releases
all such liability.  The waiver and release are part of the
consideration for the issuance of the Securities.

         19.  Authentication.  This Security shall not be valid
until the Trustee signs the certificate of authentication on the
other side of this Security.

         20.  Abbreviations.  Customary abbreviations may be used
in the name of a Securityholder or an assignee, such as: TEN COM
(=tenants in common), TEN ENT (=tenants by the entireties), JT
TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=Custodian), and U/G/M/A (=Uniform
Gifts to Minors Act).

         The Company will furnish to any Securityholder upon
written request and without charge a copy of the Indenture.  It
also will furnish the text of this Security in larger type.
Requests may be made to:  Comptek Research, Inc., 2732 Transit

Period of Usability

     Subject  to the provisions of Section 4 hereof, the  Company
shall  use  its  best  efforts  to file  a  "shelf"  Registration
Statement  (a  "Shelf Registration") on Form  S-3  or  any  other
appropriate form pursuant to Rule 415 (or similar rule  that  may
be  adopted  by  the SEC) under the Securities Act  for  all  the
Registrable  Securities, which form shall be  available  for  the
sale  of  the  Registrable  Securities  in  accordance  with  the
intended  method or methods of distribution thereof, as  promptly
as  practicable after the Closing and in any event not later than
30  days  after the Closing and to cause such Shelf  Registration
Statement  to  be declared effective as promptly  as  practicable
after  the Closing and in any event not later than 90 days  after
the Closing.

     The  Company  agrees  to use its best efforts  to  keep  the
Registration  Statement  continuously effective  and  usable  for
resale  of Registrable Securities until two (2) years   from  the
Effective  Date or such shorter period which will terminate  when
all  the  Registrable  Securities covered  by  such  Registration
Statement  have been sold pursuant to such Registration Statement
or  when  all  Registrable Securities otherwise  have  been  sold
pursuant  to Rule 144 or are freely tradeable in essentially  the
same   manner   as   contemplated  in  Section   4   below   (the
"Effectiveness Period").

4.   Registration Procedures

     In  connection  with  the Company's  obligation  to  file  a
Registration  Statement  as provided in  Section  3  hereof,  the
Company will as expeditiously as possible:

     (a)  before filing a Registration Statement or Prospectus or any
amendments or supplements thereto, furnish to Purchaser  and  the
holders   of   the   Registrable  Securities  covered   by   such
Registration Statement a copy of all such documents  proposed  to
be  filed,  which  documents will be subject  to  the  review  of
Purchaser  and  such holders and the Company will  not  file  any
Registration Statement or amendment thereto or any Prospectus  or
any  supplement  thereto to which the holders of  a  majority  in
aggregate principal amount of the Registrable Securities  covered
by  such Registration Statement shall reasonably object (provided
that  the  Company may assume, for the purposes of the  foregoing
that any holder of Registrable Securities has no objection if the
Company  has  not  received notice from such holder  within  five
business days after delivery of such documents to such holder);

     (b)  prepare and file with the SEC such amendments and post-
effective  amendments  to the Registration  Statement,  and  such
supplements to the Prospectus, as may be required by  the  rules,
regulations  or instructions applicable to the registration  form
utilized  by  the Company or by the Securities Act or  rules  and
regulations  thereunder  for  shelf  registration  or   otherwise
necessary  to keep the Registration Statement effective  for  the
applicable period and cause the Prospectus as so supplemented  to
be  filed  pursuant  to Rule 424 under the  Securities  Act;  and
comply with the provisions of the Securities Act with respect  to
the  disposition  of all securities covered by such  Registration
Statement  during  the applicable period in accordance  with  the
intended methods of disposition by the sellers thereof set  forth
in such Registration Statement or supplement to the Prospectus;

     (c)  notify Purchaser and the holders of Registrable Securities
promptly, and confirm such advice in writing:

          (1)  when the Prospectus or any Prospectus supplement or post-
     effective amendment has been filed, and, with respect to the
     Registration Statement or any post-effective amendment, when the
     same has become effective;
     
          (2)  of the issuance by the SEC of any stop order suspending the
     effectiveness of the Registration Statement or the initiation of
     any proceedings for that purpose;
     
          (3)  of the receipt by the Company of any notification with
     respect to the suspension of the qualification of the Registrable
     Securities for sale in any jurisdiction or the initiation or
     threatening of any proceeding for such purpose; and
     
          (4)  of the happening of any event which makes any statement made
     in the Registration Statement, the Prospectus or any document
     incorporated therein by reference untrue or which requires the
     making  of  any  changes in the Registration Statement,  the
     Prospectus or any document incorporated therein by reference in
     order to make the statements therein not misleading.
     
     (d)  make every reasonable effort to obtain the withdrawal of any
order  suspending the effectiveness of the Registration Statement
at the earliest possible moment;

     (e)   furnish, without charge, to Purchaser and each selling
holder of Registrable Securities, at least one conformed copy  of
the  Registration  Statement  and  any  post-effective  amendment
thereto,  including  financial  statements  and  schedules,   all
documents  incorporated  therein by reference  and  all  exhibits
(including those incorporated by reference);

     (f)  deliver to Purchaser and each selling holder of Registrable
Securities  without  charge, as many  copies  of  the  Prospectus
(including  each  preliminary prospectus) and  any  amendment  or
supplement  thereto as such Persons may reasonably  request;  the
Company consents to the use of the Prospectus or any amendment or
supplement  thereto by each of Purchaser and the selling  holders
of  Registrable  Securities in connection with the  offering  and
sale  of the Registrable Securities covered by the Prospectus  or
any amendment or supplement thereto;

     (g)   at  least  14 days prior to filing of the Registration
Statement, use its best efforts to furnish by certified  mail  to
the  beneficial  holders of the Registrable  Securities,  at  the
addresses of record specified on the transfer books held  by  the
Trustee, notice of the Company's intention to file a Registration
Statement  and request that all holders of Registrable Securities
desiring  to  sell their Registrable Securities pursuant  to  the
Registration Statement notify the Company promptly in writing;

     (h)   cooperate  with Purchaser and the selling  holders  of
Registrable  Securities to facilitate the timely preparation  and
delivery  of certificates representing Registrable Securities  to
be sold and not bearing any restrictive legends;

     (i)  use its best efforts to cause the Registrable Securities
covered  by the Registration Statement to be registered  with  or
approved by such governmental agencies or authorities as  may  be
necessary  to enable the seller or sellers thereof to  consummate
the   disposition   of  such  Registrable  Securities   in   such
jurisdictions within the United States of America as the  sellers
may  specify in response to inquiries to be made by the  Company,
provided  that  the  Company  will not  be  required  to  qualify
generally to do business in any jurisdiction where it is not then
so  qualified  or to take any action which would  subject  it  to
general service of process in any such jurisdiction where  it  is
not then so subject;

     (j)  if any event shall occur as a result of which the Board of
Directors  of  the Company shall determine that it is  necessary,
based  on  the  opinion of counsel for the  Company  or  for  the
holders of a majority of the Registrable Securities, to amend  or
supplement  the  Prospectus in order to make the  Prospectus  not
misleading in the light of the circumstances existing at the time
it  is  delivered to a purchaser, prepare a supplement  or  post-
effective amendment to the Registration Statement or the  related
Prospectus  or any document incorporated therein by reference  or
file any other required document so that, as thereafter delivered
to  the  purchasers of the Registrable Securities, the Prospectus
will  not contain an untrue statement of a material fact or  omit
to  state  any  material fact necessary to  make  the  statements
therein not misleading;

     (k)  obtain a CUSIP number for all Registrable Securities (unless
already obtained), not later than the Effective Date;

     (l)  make available for inspection during normal business hours
by  a  representative of the holders of a majority of Registrable
Securities  and  any  attorney  or accountant  retained  by  such
representative,  all  material  financial  and   other   records,
pertinent and material corporate documents and properties of  the
Company,   and  cause  the  Company's  officers,  directors   and
employees to supply all material information reasonably requested
by  such  representative or any such attorney  or  accountant  in
connection  with  the Registration Statement; provided  that  all
such records, information or documents shall be kept confidential
by such Persons unless disclosure of such records, information or
documents  is  required by court or administrative  order  or  is
generally  available  to the public other than  as  a  result  of
disclosure in violation of this paragraph (l);

(m)  otherwise use its best efforts to comply with all applicable
rules and regulations of the SEC, and make generally available to
their security holders an earning statement satisfying the
provisions of Section 11(a) of the Securities Act (in accordance
with Rule 158 thereunder or otherwise), no later than 45 days
after the end of the 12-month period (or 90 days, if such period
is a fiscal year) beginning with the first month of the Company's
first fiscal quarter commencing after the Effective Date, which
statements shall cover said 12-month period;
(n)  cause the Indenture to be qualified under the Trust
Indenture Act of 1939, as amended from time to time (the "TIA"),
and, in connection therewith, cooperate with the Trustee under
the Indenture and the holders of the Debentures to effect such
changes to the Indenture as may be required for the Indenture to
be so qualified in accordance with the terms of the TIA and
execute, and use their best efforts to cause the Trustee to
execute, all documents as may be required to effect such changes,
and all other forms and documents required to be filed with the
SEC to enable the Indenture to be so qualified in a timely
manner; and
(o)  if at any time an event of the kind described in Section
4(j) shall occur, promptly notify Purchaser and the holders of
Registrable Securities that the use of the Prospectus must be
discontinued.
     Each  selling holder of Registrable Securities as  to  which
any  registration is being effected agrees, as a condition to the
registration  obligations with respect to  such  holder  provided
herein, to furnish to the Company such information regarding  the
distribution of such securities as the Company may from  time  to
time reasonably request.

     Each  holder of Registrable Securities agrees by acquisition
of  such Registrable Securities that, upon receipt of any  notice
from  the  Company described in paragraph 4(o), such holder  will
forthwith discontinue disposition of Registrable Securities until
such  holder's  receipt  of the copies  of  the  supplemented  or
amended Prospectus contemplated by Section 4(j) hereof, or  until
it is advised in writing by the Company (which notice the Company
shall  give as promptly as reasonably possible), that the use  of
the  Prospectus may be resumed, and has received  copies  of  any
additional  or  supplemental filings which  are  incorporated  by
reference in the Prospectus, and, if so directed by the  Company,
such  holder  will  deliver  to the  Company  (at  the  Company's
expense)  all  copies, other than permanent file copies  then  in
such   holder's  possession,  of  the  Prospectus  covering  such
Registrable  Securities current at the time of  receipt  of  such
notice.

     Notwithstanding any other provision in this  Agreement,  the
Company shall not under any circumstances be entitled to exercise
its  rights  under  Section 4(j) to defer  sales  of  Registrable
Securities  except  as follows: the Company may  defer  sales  of
Registrable  Securities in accordance with  Section  4(j)  for  a
period not to exceed an aggregate of sixty (60) days in any three
hundred  sixty  five (365) day period, and the  period  in  which
sales  of  Registrable Securities are suspended shall not  exceed
fifteen  (15)  days  unless the Company  shall  deliver  to  such
holders  of Registrable Securities one or more subsequent notices
to  the  effect  set forth above, each of which  shall  have  the
effect  of extending the period during which sales of Registrable
Securities are deferred by up to an additional fifteen (15) days,
or such shorter period of time as is specified in such subsequent
notice.

5.   Registration Expenses

     (a)  All expenses (other than Selling Expenses) incident to the
Company's  performance  of  or compliance  with  this  Agreement,
including without limitation:

          (1)  all registration, filing and listing fees;
     
          (2)  fees and expenses of compliance with securities or blue sky
     laws (including reasonable fees and disbursements of one counsel
     in connection with blue sky qualifications of the Registrable
     Securities and determination of their eligibility for investment
     under the laws of such jurisdictions as the holders of a majority
     in principal amount of the Registrable Securities being sold may
     reasonably designate);
     
          (3)  printing, messenger, telephone and delivery expenses;
     
          (4)  fees and disbursements of counsel for the Company;
     
          (5)  fees and disbursements of all independent certified public
     accountants of the Company (including the expenses of any special
     audit necessary to satisfy the requirements of the Securities Act
     and any "cold comfort" letters required by or incident to such
     performance);
     
          (6)  securities acts liability insurance if the Company so
     desires;
     
          (7)  fees and expenses of other Persons retained by the Company;
     and
     
          (8)  fees and expenses associated with any NASD filing required
     to be made in connection with the Registration Statement
     
(all  such  expenses being herein called "Registration Expenses")
will  be  borne  by  the  Company,  regardless  of  whether   the
Registration Statement becomes effective.

     The  Company  will, in any event, pay its internal  expenses
(including, without limitation, all salaries and expenses of  its
officers  and  employees performing legal or accounting  duties),
the  expense of any annual audit, the fees and expenses  incurred
in connection with the listing of the securities to be registered
on  a  securities exchange, rating agency fees and the  fees  and
expenses  of  any Person, including special experts, retained  by
the Company.

6.   Indemnification and Contribution

     (a)  Indemnification by the Company.  The Company agrees, to
indemnify   and   hold  harmless  each  holder   of   Registrable
Securities,  its officers, directors, employees  and  agents  and
each Person who controls such holder within the meaning of either
Section  15  of the Securities Act or Section 20 of the  Exchange
Act (each such person being sometimes hereinafter referred to  as
an  "Indemnified  Holder") from and against all  losses,  claims,
damages, liabilities and expenses (including reasonable costs  of
investigation  and legal expenses) arising out of or  based  upon
any  untrue  statement or alleged untrue statement of a  material
fact contained in any Registration Statement or Prospectus or  in
any  amendment  or  supplement  thereto  or  in  any  preliminary
prospectus,  or  arising out of or based  upon  any  omission  or
alleged omission to state therein a material fact required to  be
stated  therein or necessary to make the statements  therein  not
misleading,  except  insofar  as such  losses,  claims,  damages,
liabilities or expenses arise out of or are based upon  any  such
untrue  statement  or omission or allegation thereof  based  upon
information  furnished  to the Company by  such  holder,  or  its
representatives,  for use therein; provided,  however,  that  the
Company  shall not be liable in any such case to the extent  that
any such loss, claim, damage, liability or expense arises out  of
or  is based upon an untrue statement or alleged untrue statement
or   omission   or  alleged  omission  made  in  any  preliminary
prospectus if (i) such holder failed to send or deliver a copy of
the   Prospectus  with  or  prior  to  the  delivery  of  written
confirmation of the sale of Registrable Securities and  (ii)  the
Prospectus   would  have  corrected  such  untrue  statement   or
omission;  and provided further, that the Company  shall  not  be
liable  in any such case to the extent that any such loss, claim,
damage,  liability or expense arises out of or is based  upon  an
untrue  statement  or  alleged untrue statement  or  omission  or
alleged  omission in the Prospectus, if such untrue statement  or
alleged  untrue  statement,  omission  or  alleged  omission   is
corrected in an amendment or supplement to the Prospectus and if,
having  previously been furnished by or on behalf of the  Company
with copies of the Prospectus as so amended or supplemented, such
holder  thereafter fails to deliver such Prospectus as so amended
or  supplemented, prior to or concurrently with  the  sale  of  a
Registrable  Security to the person asserting such  loss,  claim,
damage,  liability  or  expense who  purchased  such  Registrable
Security  which  is the subject thereof from such  holder.   This
indemnity will be in addition to any liability which the  Company
may   otherwise   have.    The  Company   will   also   indemnify
underwriters,  selling  brokers,  dealer  managers  and   similar
securities   industry   professionals   participating   in    the
distribution,  their officers and directors and each  Person  who
controls  such Persons (within the meaning of Section 15  of  the
Securities  Act or Section 20 of the Exchange Act)  to  the  same
extent  as provided above with respect to the indemnification  of
the holders of Registrable Securities.

     If  any  action  or  proceeding (including any  governmental
investigation  or  inquiry) shall be brought or asserted  against
any  Indemnified  Holder  in respect of which  indemnity  may  be
sought  from the Company, such Indemnified Holder shall  promptly
notify the Company in writing (but the omission to so notify  the
Company  shall not relieve it of any liability that it  may  have
against   any  Indemnified  Holder  otherwise  than  under   this
subsection  unless the Company has been materially prejudiced  by
such  delay),  and the Company shall assume the defense  thereof,
including  the  employment of counsel reasonably satisfactory  to
such  Indemnified  Holder  and  the  payment  of  all  reasonable
expenses.    Indemnified   Holders   shall   have   the    right,
collectively, to employ their own counsel in any such action  and
to  participate in the defense thereof, but the fees and expenses
of  such  counsel shall be the expense of the Indemnified Holders
unless (a) the Company shall have failed to assume the defense of
such  action or proceeding or (b) the named parties to  any  such
action  or  proceeding (including any impleaded parties)  include
the  Indemnified  Holders and the Company,  and  the  Indemnified
Holders shall have been advised by counsel that there may be  one
or more legal defenses available to the Indemnified Holders which
are  different  from  or  additional to those  available  to  the
Company  (in  which case, if the Indemnified Holders  notify  the
Company in writing that they elect to employ their own counsel at
the  expense of the Company, the Company shall not have the right
to  assume the defense of such action or proceeding on behalf  of
the  Indemnified Holders, it being understood, however, that  the
Company  shall  not, in connection with any one  such  action  or
proceeding  or  separate  but substantially  similar  or  related
actions  or proceedings in the same jurisdiction arising  out  of
the  same general allegations or circumstances, be liable for the
reasonable  fees and expenses of more than one separate  firm  of
attorneys  at  any  time for the Indemnified Holders  which  firm
shall  be  designated  in  writing  by  the  Indemnified  Holders
representing  at  least  a  majority of the  aggregate  principal
amount of the outstanding Debentures).  The Company shall not  be
liable  for  any  settlement  of any such  action  or  proceeding
effected  without  its written consent, but if settled  with  its
written  consent,  or  if  there be  a  final  judgment  for  the
plaintiff in any such action or proceeding, the Company agrees to
indemnify  and  hold harmless the Indemnified  Holders  from  and
against  any  loss or liability by reason of such  settlement  or
judgment.   The  Company  shall not, without  the  prior  written
consent of the Indemnified Holders, effect any settlement of  any
pending  or  threatened  proceeding  in  respect  of  which   any
Indemnified  Holder is or could have been a party  and  indemnity
could  have  been  sought hereunder by such  Indemnified  Holder,
unless such settlement includes an unconditional release of  such
Indemnified  Holder  from all liability or claims  that  are  the
subject matter of such proceeding.

     (b)  Indemnification by Holder of Registrable Securities.  Each
holder  of  Registrable Securities agrees to indemnify  and  hold
harmless   the  Company,  its  respective  directors,   officers,
employees  and agents and each Person, if any, who  controls  the
Company within the meaning of either Section 15 of the Securities
Act  or Section 20 of the Exchange Act to the same extent as  the
foregoing  indemnity from the Company to such  holder,  but  only
with respect to information relating to such holder furnished  in
writing  by such holder, or its representatives, for use  in  any
Registration  Statement  or  Prospectus,  or  any  amendment   or
supplement thereto, or any preliminary prospectus.  In  case  any
action or proceeding shall be brought against the Company or  its
respective directors, officers, employees or agents or  any  such
controlling person, in respect of which indemnity may  be  sought
against  a  holder of Registrable Securities, such  holder  shall
have the rights and duties given the Company, and the Company  or
its  respective directors, officers, employees or agents or  such
controlling person shall have the rights and duties given to each
holder  by  the  preceding paragraph.   In  no  event  shall  the
liability   of  any  selling  holder  of  Registrable  Securities
hereunder  be  greater in amount than the dollar  amount  of  the
proceeds received by such holder upon the sale of the Registrable
Securities giving rise to such indemnification obligation.   Each
holder    of   Registrable   Securities   will   also   indemnify
underwriters,  selling  brokers,  dealer  managers  and   similar
securities   industry   professionals   participating   in    the
distribution,  their officers and directors and each  Person  who
controls  such Persons (within the meaning of Section 15  of  the
Securities  Act or Section 20 of the Exchange Act)  to  the  same
extent  as provided above with respect to the indemnification  of
the   Company.   The  Company  and  each  holder  of  Registrable
Securities   shall  be  entitled  to  receive  indemnities   from
underwriters,  selling  brokers,  dealer  managers  and   similar
securities   industry   professionals   participating   in    the
distribution, to the same extent as provided above  with  respect
to   information  so  furnished  in  writing  by   such   Persons
specifically  for  inclusion  in any Prospectus  or  Registration
Statement.

     (c)  Contribution.  If the indemnification provided for in this
Section  6  is unavailable to an indemnified party under  Section
6(a)  or  Section 6(b) hereof (other than by reason of exceptions
provided  in  those Sections) in respect of any  losses,  claims,
damages,  liabilities or expenses referred to therein, then  each
applicable  indemnifying  party, in  lieu  of  indemnifying  such
indemnified party, shall contribute to the amount paid or payable
by  such  indemnified party as a result of such  losses,  claims,
damages,  liabilities or expenses, (i) in such proportion  as  is
appropriate  to  reflect the relative benefits  received  by  the
Company from the sale of the Debentures to Purchaser pursuant  to
the  Purchase  Agreement  on the one  hand  and  each  holder  of
Registrable  Securities  from  the offering  of  the  Registrable
Securities  by  such holder, on the other hand, or  (ii)  if  the
allocation  provided  by clause (i) above  is  not  permitted  by
applicable  law, in such proportion as is appropriate to  reflect
not  only  the relative benefits referred to in clause (i)  above
but  also  the relative fault of the Company on the one hand  and
each  holder of Registrable Securities on the other in connection
with  the  statements or omissions that resulted in such  losses,
claims,  damages, or liabilities, as well as the  other  relevant
equitable considerations.  The relative benefits received by  the
Company on the one hand and each holder of Registrable Securities
on  the other shall be deemed to be in the same proportion as the
aggregate amount paid by Purchaser to the Company pursuant to the
Purchase  Agreement for the Registrable Securities  purchased  by
such holder that were sold pursuant to the Registration Statement
bears  to  the difference (the "Difference") between  the  amount
such  holder paid for the Registrable Securities that  were  sold
pursuant to the Registration Statement and the amount received by
such  holder  from  such  sale.   The  relative  fault  shall  be
determined  by  reference  to, among other  things,  whether  the
untrue  or  alleged untrue statement of a material  fact  or  the
omission or alleged omission to state a material fact relates  to
information supplied by the Company or the particular holder  and
the  parties'  relative intent, knowledge, access to  information
and  opportunity to correct or prevent such untrue  statement  or
omission.   The Company and the holders of Registrable Securities
agree  that  it  would not be just and equitable if contributions
pursuant to this subsection (c) were to be determined by pro rata
allocation  or  by any other method of allocation that  does  not
take  account of the equitable consideration referred to  in  the
first  sentence of this subsection (c).  The amount  paid  by  an
indemnified party as a result of the losses, claims,  damages  or
liabilities referred to in the first sentence of this  subsection
(c)  shall  be  deemed  to include any legal  or  other  expenses
reasonably incurred by such indemnified party in connection  with
investigation  or defending against any action or claim  that  is
the   subject  of  this  subsection  (c).   Notwithstanding   the
provision  of  this  subsection (c), each holder  of  Registrable
Securities  shall  not be required to contribute  any  amount  in
excess  of the amount by which the Difference exceeds the  amount
of  any  damages that such holder has otherwise been required  to
pay  by  reason  of  such untrue or alleged untrue  statement  or
omission  or  alleged omission.  No person guilty  of  fraudulent
misrepresentation  (within the meaning of Section  11(f)  of  the
Securities  Act),  shall  be entitled to  contribution  from  any
person who was not guilty of such fraudulent misrepresentation.

7.   Rule 144

     During  the  Effectiveness Period and for  so  long  as  the
Company is subject to the reporting requirements of Section 13 or
15  of the Exchange Act, the Company covenants that it will  file
the  reports required to be filed by it under the Securities  Act
and  Section 13(a) or 15(d) of the Exchange Act and the rules and
regulations adopted by the SEC thereunder.  If the Company is not
subject to the reporting requirements of Section 13 or 15 of  the
Exchange Act, the Company also covenants that it will provide the
information  required  pursuant  to  Rule  144A(d)(4)  under  the
Securities  Act  upon  the request of any holder  of  Registrable
Securities  which continues to be "restricted securities"  within
the  meaning of Rule 144(a)(3) under the Securities  Act  and  it
will  take  such further action as any holder of such Registrable
Securities  may  reasonably request, all to the  extent  required
from  time  to time to enable such holder to sell its Registrable
Securities  without registration under the Securities Act  within
the  limitation of the exemptions provided by (a) Rule 144  under
the  Securities  Act, as such Rule may be amended  from  time  to
time,  so  long  as  such provision does not require  the  public
filing  of information relating to the Company which the  Company
is  not  otherwise required to file, or (b) any similar  rule  or
regulation hereafter adopted by the SEC that does not require the
public  filing of information relating to the Company.  Upon  the
request of any holder of Registrable Securities, the Company will
deliver to such holder a written statement as to whether  it  has
complied with such requirements.

8.   Miscellaneous

     (a)  No Inconsistent Agreements.  The Company will not on or
after  the  date of this Agreement enter into any agreement  with
respect to their securities which is inconsistent with the rights
granted  to  the  holders  of  Registrable  Securities  in   this
Agreement or otherwise conflicts with the provisions hereof.  The
rights granted to the holders of Registrable Securities hereunder
do not in any way conflict with and are not inconsistent with the
rights  granted to the holders of the Company's securities  under
any such agreements.

     (b)  Adjustments Affecting Registrable Securities.  The Company
will  not  take any action, or permit any change to  occur,  with
respect  to  the  Registrable Securities  which  would  adversely
affect  the  ability of the holders of Registrable Securities  to
include  such Registrable Securities in a registration undertaken
pursuant to this Agreement.
