THE COMPANY


     L-3 Communications is a leading merchant supplier of sophisticated secure
communication systems and specialized communication products. We produce
secure, high data rate communication systems, microwave components, avionics
and ocean systems and telemetry, instrumentation and space products. These
systems and products are critical elements of virtually all major
communication, command and control, intelligence gathering and space systems.
Our systems and specialized products are used to connect a variety of airborne,
space, ground- and sea-based communication systems and are used in the
transmission, processing, recording, monitoring and dissemination functions of
these communication systems. Our customers include the U.S. department of
defense, certain U.S. government intelligence agencies, major aerospace and
defense contractors, foreign governments and commercial customers. For the
twelve-month period ended September 30, 1998, we had pro forma sales of
$1,139.7 million and pro forma EBITDA (as defined in footnote 8 under "Selected
Financial Information") of $148.4 million. Our funded backlog as of September
30, 1998 was $813.8 million. These results reflect internal growth and the
execution of our strategy of acquiring businesses that complement or extend our
product lines.


     Our business areas employ proprietary technologies and capabilities and
have leading positions in their respective primary markets. We have organized
our operations into two primary business areas: Secure Communication Systems
and Specialized Communication Products. For the twelve-month period ended
September 30, 1998, the Secure Communication Systems business area generated
approximately $481.5 million of pro forma sales and $61.2 million of pro forma
EBITDA, and the Specialized Communication Products business area generated
$658.2 million of pro forma sales and $87.2 million of pro forma EBITDA. In
addition, we are seeking to expand our products and technologies in commercial
markets as we discuss under "--Emerging Commercial Products" below.


     SECURE COMMUNICATION SYSTEMS. We are the established leader in secure,
high data rate communications for military and other U.S. government
reconnaissance and surveillance applications. Our Secure Communication Systems
operations are located in Salt Lake City, Utah, Camden, New Jersey and
Shrewsbury, New Jersey. These operations are predominantly cost plus, sole
source contractors supporting long-term programs for the U.S. armed forces and
classified customers.


                                       1
<PAGE>

   Our major secure communication programs and systems include:

    o  secure data links for airborne, satellite, ground- and sea-based remote
       platforms for information collection, command and control and
       dissemination to users in real time;

    o  strategic and tactical signal intelligence systems that detect, collect,
       identify, analyze and disseminate information and related support
       contracts for military and intelligence efforts;

    o  secure telephone, fax and network equipment and encryption management;
 

    o  communication software support services to military and related
       government intelligence markets; and

    o  communications systems for surface and undersea platforms and manned
       space flights.

     We believe that we have developed virtually every high bandwidth data link
that is currently used by the military for surveillance and reconnaissance. We
are also a leading supplier of communication software support services to
military and related government intelligence markets. In addition to these core
government programs, we are capitalizing on our technology base by expanding
into related commercial communication equipment markets. For instance, we are
applying our high data rate communications and archiving technology to the
medical image archiving market and our wireless communication expertise to
develop local wireless loop telecommunications equipment for the last mile
interconnect.

     SPECIALIZED COMMUNICATION PRODUCTS. This business area encompasses three
product categories:

     Microwave Components. We are the preeminent worldwide supplier of
commercial off-the-shelf, high-performance microwave components and frequency
monitoring equipment. Our microwave products are sold under the
industry-recognized Narda brand name through a standard catalog to wireless,
industrial and military communication markets. We also provide
state-of-the-art, space-qualified communication components including channel
amplifiers and frequency filters for the commercial communications satellite
market serving major military and commercial frequencies, including Ka band.
Approximately 79% of Microwave Components sales for the nine-month period ended
September 30, 1998 were made to commercial customers, including Loral Space &
Communications, Ltd., Motorola, Inc., Lucent Technologies Inc., AT&T Corp. and
Lockheed Martin Corporation ("Lockheed Martin").

     Avionics and Ocean Products. Avionics and Ocean Products include our
aviation recorders, display systems, antenna systems, acoustic undersea warfare
systems and naval power distribution, conditioning, switching and protection
equipment for naval ships and submarines. We are the world's leading
manufacturer of commercial cockpit voice and flight data recorders (known as
"black boxes"). These recorders are sold under the Fairchild brand name both to
aircraft manufacturers and to the world's major airlines for their existing
fleets of aircraft. Our aviation recorders are also installed on military
transport aircraft throughout the world. We provide military and high-end
commercial displays for use in military aircraft. We also manufacture high
performance surveillance and precision millimeter wave antennas and related
equipment for U.S. Air Force, U.S. Army and U.S. Navy aircraft and are the
leading supplier of ground-based radomes. We are one of the world's leading
product suppliers of acoustic undersea warfare systems and airborne dipping
sonar systems to the U.S. and over 20 foreign navies. We are the only fully
integrated, full-line provider of qualified turnkey electrical power delivery
and management systems for U.S. Navy surface ships and submarines.

     Telemetry, Instrumentation and Space Products. Our Telemetry,
Instrumentation and Space Products operations develop and manufacture
commercial off-the-shelf, real-time data collection and transmission products
and components for missile, aircraft and space-based electronic systems. These
products are used to gather flight data and other critical information and
transmit it from air or space to the ground. Telemetry products are also used
for range safety and training applications to simulate battlefield situations.
We are also a leading global satellite communications systems provider offering
 


                                       2
<PAGE>

systems and services used in the satellite transmission of voice, video and
data through earth stations for uplink and downlink terminals. We provide
global satellite communications systems and services to customers that include
foreign post, telephone and telegraph administrations, domestic and
international prime communications infrastructure contractors,
telecommunications and satellite service providers, broadcasters and
media-related companies, government agencies and large corporations. We also
provide commercial, off-the-shelf satellite control software, telemetry,
tracking and control ("TT&C"), mission processors and software engineering
services to the worldwide military, civilian and commercial satellite markets.

     EMERGING COMMERCIAL PRODUCTS. Building upon our core technical expertise
and capabilities, we are seeking to expand into several closely aligned
commercial business areas and applications. Emerging Commercial Products
currently include the following four niche markets:

    o  medical archiving and simulation systems;

    o  local wireless loop telecommunications equipment;

    o  airport security equipment; and

    o  information network security.

     A majority of these commercial products were developed based on technology
used in our military businesses with relatively small additional expense. We
are applying our technical capabilities in high data rate communications and
archiving technology developed in our Secure Communication Systems business
area to the medical image archiving market together with the General Electric
Company's medical systems business. Based on secure, high data rate
communication technology also developed in our Secure Communication Systems
business area, we have developed local wireless loop telecommunications
equipment that is primarily designed for emerging market countries and rural
areas where voice and data communication infrastructure is inadequate or does
not exist. We have completed the development phase for the local wireless loop
telecommunications equipment and have begun deliveries. In addition, the
Federal Aviation Administration awarded us a development contract for next
generation airport security equipment for explosive detection. On November 23,
1998, we received FAA certification for our eXaminer 3DX (Trade Mark)  6000
system which is the only second-generation system to receive certification and
the only system to generate full, three-dimensional images of all objects in a
piece of baggage. To capitalize on commercial opportunities for the information
security technologies we developed in our Secure Communication Systems business
area, we have also created a new subsidiary focusing on developing and
marketing secure information and communication systems for commercial clients.
This subsidiary acquired a network security software product through a
majority-owned joint venture. We released the third generation of this network
security software, ExpertTM 3.0, on November 9, 1998. Taken together, revenues
generated from our Emerging Commercial Products have not yet been material to
us.

BUSINESS STRATEGY

     We have successfully integrated the business units we acquired from
Lockheed Martin and enhanced our operating efficiency by reducing overhead
expenses and reorganizing our facilities. These efforts resulted in
improvements in sales, profitability and obtaining competitive contracts. We
have used and intend to continue to use our market position, diverse program
base and favorable mix of cost plus to fixed price contracts to enhance our
profitability and to establish L-3 as the premier merchant supplier of
communication systems and products to the major prime contractors in the
aerospace/defense industry as well as the U.S. government. Our strategy to
continue to achieve our objectives includes:

      o   EXPAND MERCHANT SUPPLIER RELATIONSHIPS. Due to our strong
relationships with prime contractors and our independent status, we intend to
grow by expanding our share of current programs, by participating in new
programs and by positioning L-3 Communications as the desired merchant supplier
to more than one bidder on prime contract bids.


                                       3
<PAGE>

      o  SUPPORT CUSTOMER REQUIREMENTS. We will continue to align our research
and development, manufacturing and new business efforts to complement our
customers' requirements, and we will provide state-of-the-art products in order
to maintain and expand current customer relationships as well as to create new
ones.

      o  ENHANCE OPERATING MARGINS. We intend to continue to enhance our
operating margins by reducing overhead expenses and increasing productivity.

      o  LEVERAGE TECHNICAL AND MARKET LEADERSHIP POSITIONS. Our proprietary
technical capabilities have placed us at or near the top market position in
most of our key business areas. We intend to use these capabilities and make
substantial investments in research and development, technical and
manufacturing resources to strengthen our market positions as well as to pursue
commercial opportunities in other areas.

      o  MAINTAIN DIVERSIFIED BUSINESS MIX. We will maintain our favorable mix
of predictable profitability (typical of cost plus contracts) and higher margin
(typical of fixed price contracts) businesses together with our significant
sole source follow-on business and attractive customer profile.

      o  CAPITALIZE ON STRATEGIC ACQUISITION OPPORTUNITIES. We intend to
continue to selectively acquire businesses which (1) have significant market
position in their business areas, (2) offer products that complement and/or
extend our existing products, (3) demonstrate positive future growth prospects
and (4) are accretive to our earnings in the first year of our ownership.


ACQUISITION STRATEGY

   
     Since our formation in April 1997, we have actively pursued our
acquisition strategy. Since completing the L-3 Acquisition, we have purchased
twelve additional businesses for an aggregate cash purchase price including
assumed debt and expenses, net of cash acquired, of approximately $534.0
million, subject to certain post-closing adjustments, and in certain cases
additional consideration based on post-closing performance. We consider and
execute strategic acquisitions on an ongoing basis and may be evaluating
acquisitions or engaged in acquisition negotiations at any given time. We have
reached agreement on or are in discussions regarding a number of potential
acquisition opportunities and expect to use our bank credit facilities to fund
these transactions if we proceed with them. See "Management's Discussion and
Analysis of Results of Operations and Financial Condition -- Liquidity and
Capital Resources".
    


RECENT DEVELOPMENTS

     SPD Technologies, Inc. On August 13, 1998, we acquired all of the
outstanding common stock of SPD Technologies, Inc. ("SPD") for $230.0 million
in cash, subject to certain post-closing adjustments. SPD is the leading
supplier to the U.S. Navy for subsystems that manage, control, distribute,
protect and condition electrical power in surface ships and submarines. SPD's
major products include electronic solid state protection products, switchgear,

     Microdyne Corporation. On December 3, 1998, we signed an agreement to
acquire all of the outstanding common stock of Microdyne Corporation
("Microdyne") for approximately $90.0 million in cash, including the repayment
of Microdyne's debt. For the fiscal year ended September 30, 1998, Microdyne
reported actual revenues of $58.3 million, operating income of $1.3 million and
net income of $0.3 million. On a pro forma basis, including acquisitions
Microdyne made during its 1998 fiscal year as if they had occurred at the
beginning of its fiscal year, Microdyne's revenues would have been

$73.5 million, operating income would have been $3.6 million and net income
would have been $0.9 million. Microdyne's actual earnings before interest,
taxes, depreciation and amortization for the recent fiscal year was $2.9
million. Pro forma earnings before interest, taxes, depreciation and
amortization would have been $11.1 million before non-recurring charges of $5.1
million primarily for the write-off of acquired in-process research and
development costs. Pursuant to the acquisition agreement, one of our
subsidiaries has purchased 91.9% of the common stock of Microdyne in a cash
tender offer. We expect to complete the merger of Microdyne with this
subsidiary in early 1999. Microdyne is a leading global developer and
manufacturer of aerospace telemetry receivers, secure communications and
technical support services, including specialized telemetry high-frequency
radios used in aerospace and satellite communications for data gathering and
analysis. Microdyne also provides products for the government and commercial
signal intelligence markets and support and repair services for electronic
products companies. Microdyne's aerospace telemetry products will enable us to
provide integrated solutions to our space customers' requirements for command,
control, telemetry and tracking. The purchase of shares of Microdyne common
stock was financed using cash and borrowings under our bank credit facilities.

     Proposed Equity Offering. Holdings and certain selling stockholders are
currently contemplating a public offering in the United States and
internationally of 9,250,000 shares (excluding the underwriters' over-allotment
option) of the common stock of Holdings (the "Proposed Equity Offering").
Holdings intends to use the net proceeds of the Proposed Equity Offering to
repay any existing indebtedness under the Senior Credit Facilities (as defined
later in this prospectus) and for general corporate purposes, including
potential acquisitions. On January 5, 1999, Holdings filed a Registration
Statement on Form S-1 (File No. 333-70125) with the SEC in connection with the
Proposed Equity Offering.


HISTORY


     Holdings, which owns all of our common stock, was formed in April 1997 by
Mr. Frank C. Lanza, the former President and Chief Operating Officer of Loral
Corporation ("Loral"), Mr. Robert V. LaPenta, the former Senior Vice President
and Controller of Loral, Lehman Brothers Capital Partners III, L.P. and its
affiliates (the "Lehman Partnership") and Lockheed Martin to acquire (1) nine
business units previously purchased by Lockheed Martin as part of its
acquisition of Loral in April 1996 and (2) one business unit, Communication
Systems -- East (formerly known as Communication Systems -- Camden), purchased
by Lockheed Martin as part of its acquisition of the aerospace business of
General Electric Company in April 1993. In May 1998, Holdings successfully
completed the IPO, raising net proceeds of $139.5 million which Holdings
contributed to us. We raised net proceeds of $173.8 million in a concurrent
debt offering. In December 1998, we raised net proceeds of $193.7 million in
the Old Notes Offering.

                         SUMMARY OF THE EXCHANGE OFFER


The Exchange Offer..........   We are offering to exchange up to $200,000,000
                               aggregate principal amount of our new 8% Series B
                               Senior Subordinated Notes due 2008 which have
                               been registered under the Securities Act (the
                               "Exchange Notes") for a like amount of our
                               outstanding 8% Senior Subordinated Notes due 2008

                               Exchange Notes, the "Notes"). The Exchange Notes
                               are substantially identical to the Old Notes,
                               except that the Exchange Notes are freely
                               transferrable by their holders (other than as
                               provided herein), and are not subject to any
                               covenant regarding registration under the
                               Securities Act.


Interest Payments...........   Interest on the Exchange Notes will accrue from
                               the last interest payment date (February 1 or
                               August 1) on which interest was paid on the Old
                               Notes or, if no interest was paid on the Old
                               Notes, from December 11, 1998 (the "Interest
                               Payment Date").

                               any minimum aggregate principal amount of Old

                               to 5:00 p.m., New York City time, on the

                               Notes will be the four business days after the
                               Expiration Date.


Conditions to the
 Exchange Offer..............  The Exchange Offer is subject to certain
                               customary conditions, which we may waive. We
                               currently expect that each of the conditions will
                               be satisfied and that no waivers will be
                               necessary. See "The Exchange Offer--Certain
                               Conditions to the Exchange Offer". We reserve the
                               right to terminate or amend the Exchange Offer at
                               any time before the Expiration Date if any such

  Income Tax Consequences...   The exchange of notes pursuant to the Exchange
                               Offer will not be a taxable event for federal

                               Rights Agreement") dated as of December 11, 1998
                               among L-3 Communications Corporation, each of the
                               subsidiary guarantors named therein and Lehman
                               Brothers Inc. and NationsBanc Montgomery
                               Securities LLC (the "Initial Purchasers") and,
                               accordingly, there will be no increase in the
                               interest rate on the Old Notes. If you do not
                               tender your Old Notes in the Exchange Offer, you
                               will continue to hold such Old Notes and will be
                               entitled to all the rights and limitations
                               applicable thereto under the Indenture dated as
                               of December 11, 1998 among L-3 Communications
                               Corporation, the subsidiary guarantors named
                               therein and The Bank of New York relating to the
                               Old Notes and the Exchange Notes (the
                               "Indenture"), except for any rights under the
                               Registration Rights Agreement that terminate as a
                               result of the acceptance for exchange of validly
                               tendered Old Notes pursuant to the Exchange
                               Offer. If you do not tender your Old Notes, you
                               will not have any further registration or
                               exchange rights and your Old Notes will continue
                               to be subject to certain restrictions on
                               transfer. Accordingly, the trading market for
                               untendered Old Notes could be adversely affected.


Exchange Agent..............   The Bank of New York is serving as Exchange

Ranking.....................   The Exchange Notes and the subsidiary
                               guarantees are senior subordinated debts.

                               They rank behind all of our and our guarantor
                               subsidiaries' current and future indebtedness
                               (other than trade payables), except indebtedness
                               that expressly provides that it is not senior to
                               these notes and the subsidiary guarantees.

                               Assuming we had completed the offering of the
                               Old Notes and the exchange of the Exchange Notes

                               subsidiary guarantees:

                                 o  would not have been subordinated to any
                                    senior debt (excluding outstanding letters
                                    of credit); and

                                 o  would have ranked equally with $405.0
                                    million of other senior subordinated debt.


Basic Covenants
 of Indenture................  We will issue the Exchange Notes under an
                               indenture among us, the subsidiary guarantors and
                               The Bank of New York, as trustee. The indenture
                               will, among other things, restrict our ability
                               and the ability of our restricted subsidiaries

                                 o  borrow money;

                                 o  pay dividends on or purchase our stock or
                                    our restricted subsidiaries' stock;

                                 o  make investments;

                                 o  use assets as security in other
                                    transactions;

                                 o  sell certain assets or merge with or into
                                    other companies; and

                                 o  enter into transactions with affiliates.

                               Certain of our subsidiaries will not be subject
                               to the covenants in the indenture. For more
                               details, see the section "Description of the
                               Exchange Notes" under the heading "Certain
                               Covenants".

   SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA AND HISTORICAL FINANCIAL DATA

     The summary unaudited pro forma data as of September 30, 1998, for the
nine months ended September 30, 1998 and 1997 and for the year ended December
31, 1997 have been derived from, and should be read in conjunction with, the
unaudited pro forma condensed consolidated financial statements included
elsewhere in this prospectus. The unaudited pro forma condensed statement of
operations and other data reflect the L-3 Acquisition, the 1998 Acquisitions,
the Financing Transactions and the Old Notes Offering as if such transactions
had occurred on January 1, 1997. The unaudited pro forma condensed balance
sheet data reflect the Old Notes Offering as if it had occurred on September
30, 1998.

     The summary historical consolidated (combined) financial data as of and
for the nine months ended December 31, 1997 and the years ended December 31,
1996, 1995 and 1994 and the three months ended March 31, 1997 have been derived
from the audited financial statements for the respective periods. The summary
historical consolidated (combined) financial data as of and for the nine months
ended September 30, 1998 have been derived from the unaudited condensed
consolidated financial statements of the Company. In the opinion of the
Company's management, such unaudited financial statements reflect all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation of the results of operations and financial position as
of the date of and for the period presented. The results of operations for the
nine months ended September 30, 1998 are not necessarily indicative of results
for the full year. The unaudited pro forma condensed financial information may
not be indicative of the financial position and results of operations of the
Company that actually would have occurred had the Transactions (as defined
later in this prospectus) been in effect on the dates indicated or the
financial position and results of operations that may be obtained in the
future.

     The summary financial data should be read in conjunction with
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" and the Consolidated (Combined) Financial Statements of the Company
(Predecessor Company (as defined later in this prospectus)) and the Combined
Financial Statements of the Loral Acquired Businesses (as defined later in this
prospectus) and the unaudited pro forma condensed consolidated financial
information included elsewhere herein. Prior to April 1, 1996, the Predecessor
Company was only comprised of Communication Systems -- East.

(1)  Includes the results of operations of the 1998 Acquisitions from their
     respective effective dates of acquisition.

(2)  Reflects the L-3 Acquisition effective April 1, 1997.

(3)  Reflects ownership of Loral's Communication Systems -- West and Specialized
     Communication Products businesses commencing April 1, 1996.

(4)  Reflects ownership of Communication Systems -- East by Lockheed Martin
     effective April 1, 1993.

(5)  Includes a nonrecurring, noncash compensation charge of $4.4 million
     related to the initial capitalization of the Company, effective April 1,
     1997.

(6)  For periods prior to April 1, 1997, interest expense and income tax
     (benefit) provision were allocated from Lockheed Martin.

(7)  EBITDA is defined as operating income plus depreciation expense and
     amortization expense (excluding the amortization of deferred debt issuance
     costs) and the nonrecurring, noncash compensation charge of $4.4 million
     recorded effective April 1, 1997. EBITDA is not a substitute for operating
     income, net income and cash flow from operating activities as determined in
     accordance with generally accepted accounting principles as a measure of
     profitability or liquidity. EBITDA is presented as additional information
     because management believes it to be a useful indicator of the Company's
     ability to meet debt service and capital expenditure requirements.

(8)  For purposes of this computation, earnings consist of income before income
     taxes plus fixed charges. Fixed charges consist of interest on indebtedness
     plus the amortization of deferred debt issuance costs and that portion of
     lease rental expense representative of the interest element.

(9)  Earnings were insufficient to cover fixed charges by $0.5 million for the
     three months ended March 31, 1997.

(10) For purposes of this computation, cash interest expense consists of pro
     forma interest expense less amortization of deferred debt issuance costs.
       

(11) The ratios at September 30, 1998 are based on the results of operations for
     the twelve-month period ended September 30, 1998. The pro forma ratios at
     September 30, 1998 have been calculated by adding the pro forma EBITDA and
     pro forma cash interest expense for the nine months ended September 30,
     1998 and the three months ended December 31, 1997. For purposes of
     computing pro forma EBITDA for the three months ended December 31, 1997,
     pro forma operating income, depreciation expense and amortization expense
     would have been $32.9 million, $6.3 million and $6.7 million, respectively.
     Pro forma cash interest expense for the twelve-month period ended September
     30, 1998 and the year ended December 31, 1997 would have been $56.1
     million.

(12) Net debt is defined as long-term debt plus current portion of long-term
     debt less cash and cash equivalents.

                                 RISK FACTORS

     You should carefully consider the following risks as well as the other
information contained or incorporated by reference in this prospectus before
deciding to tender Old Notes in the Exchange Offer. The risk factors set forth
below are generally applicable to the Old Notes as well as the Exchange Notes.


OLD NOTES OUTSTANDING AFTER THE EXCHANGE OFFER WILL NOT HAVE REGISTRATION
RIGHTS AND WE EXPECT THE MARKET FOR SUCH OLD NOTES TO BE ILLIQUID

     If you do not exchange your Old Notes for Exchange Notes pursuant to the
Exchange Offer, you will continue to be subject to the restrictions on transfer
of such Old Notes. In general, you may not offer or sell Old Notes unless they
are registered under the Securities Act, except pursuant to an exemption from,
or in a transaction not subject to, the registration requirements of the
Securities Act and applicable state securities laws. We do not currently intend
to register the Old Notes under the Securities Act. Based on interpretations by
the staff of the Commission, we believe that Exchange Notes issued pursuant to
the Exchange Offer may be offered for resale, resold or otherwise transferred
by their holders (unless such holder is an "affiliate" of the Company within
the meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, so long
as the Old Notes were acquired in the ordinary course of the holders' business
and such holders have no arrangement with any person to participate in the
distribution of such Exchange Notes. Each broker-dealer that receives Exchange
Notes for its own account in exchange for Old Notes, where such Old Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. See "Plan of Distribution".
To the extent that Old Notes are tendered and accepted in the Exchange Offer,
the trading market for untendered and tendered but unaccepted Old Notes will be
adversely affected.


YOU CANNOT BE SURE THAT AN ACTIVE TRADING MARKET WILL DEVELOP FOR THE EXCHANGE
   NOTES

     We are offering the Exchange Notes to the holders of the Old Notes. The
Old Notes were offered and sold in December 1998 to a small number of
institutional investors and are eligible for trading in the Private Offerings,
Resale and Trading through Automatic Linkages (PORTAL) Market.

     We do not intend to apply for a listing of the Exchange Notes on a
securities exchange or on any automated dealer quotation system. There is
currently no established market for the Exchange Notes and we cannot assure you
as to the liquidity of markets that may develop for the Exchange Notes, your
ability to sell the Exchange Notes or the price at which you would be able to
sell the Exchange Notes. If such markets were to exist, the Exchange Notes
could trade at prices that may be lower than their principal amount or purchase
price depending on many factors, including prevailing interest rates and the
markets for similar securities. We expect that the Exchange Notes will be
designated for trading in the PORTAL market. The Initial Purchasers have
advised us that they currently intend to make a market with respect to the
Exchange Notes. However, the Initial Purchasers are not obligated to do so, and
any market making with respect to the Exchange Notes may be discontinued at any
time without notice. In addition, such market making activity may be limited
during the pendency of the Exchange Offer or the effectiveness of a shelf
registration statement in lieu thereof. Because Lehman Brothers Inc. is our
affiliate, following consummation of the Exchange Offer, Lehman Brothers Inc.
will be required to deliver a current "market-maker" prospectus and otherwise
comply with the registration requirements of the Securities Act in connection
with any secondary market sale of the Exchange Notes, which may affect its
ability to continue market-making activities.

     The liquidity of, and trading market for, the Exchange Notes also may be
adversely affected by general declines in the market for similar securities.
Such a decline may adversely affect such liquidity and trading markets
independent of our financial performance and prospects.


WE HAVE A SIGNIFICANT AMOUNT OF DEBT

     We incurred substantial indebtedness in connection with our acquisitions.
If the Old Notes Offering had occurred on September 30, 1998, we would have had
$605.0 million of indebtedness


                                       13
<PAGE>

outstanding, none of which would have been senior debt (excluding outstanding
letters of credit), and our ratio of pro forma earnings to pro forma fixed
charges would have been 1.5 to 1.0. In the future we may borrow more money,
subject to limitations imposed by our debt agreements.

     Based upon our current level of operations and anticipated improvements,
we believe that our cash flow from operations, together with proceeds from the
Old Notes Offering and amounts we are able to borrow under our bank credit
facilities, will be adequate to meet our anticipated requirements for working
capital, capital expenditures, research and development expenditures, program
and other discretionary investments, interest payments and scheduled principal
payments for the foreseeable future, at least for the next three years. Our
ability to make scheduled payments of principal and interest on our
indebtedness and to refinance our indebtedness depends on our future
performance. We do not have complete control over our future performance
because it is subject to economic, financial, competitive, regulatory and other
factors affecting the defense industry. It is possible that in the future our
business may not generate sufficient cash flow from operations to allow us to
service our debt and make necessary capital expenditures. If this situation
occurs, we may have to sell assets, restructure debt or obtain additional
equity capital. We cannot be sure that we would be able to do so or do so
without additional expense. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition".

     Our level of indebtedness may have important consequences on your
investment in the Notes. These consequences include:

    o  requiring a substantial portion of our cash flow from operations to be
       used to pay interest and principal on our debt and therefore be
       unavailable for other purposes including capital expenditures, research
       and development and other investments;

    o  limiting our ability to obtain additional financing in the future;

    o  incurring higher interest expense in the event of increases in interest
       rates on our borrowings which have variable interest rates;

    o  heightening our vulnerability to downturns in our business or in the
       general economy and restricting us from making acquisitions, introducing
       new technologies and products or exploiting business opportunities; and

    o  limiting our ability to borrow additional funds, dispose of assets or pay
       cash dividends. Failure to comply with such covenants could result in an
       event of default which, if not cured or waived, could have a material
       adverse effect on our financial position and results of operations due to
       financial and restrictive covenants.

     See "Description of Certain Indebtedness".


OUR ACQUISITION STRATEGY INVOLVES CERTAIN RISKS

     We intend to acquire companies which complement our business. We cannot
assure you, however, that we will be able to identify acquisition candidates on
commercially reasonable terms or at all. If we make additional acquisitions, we
also cannot be sure that any anticipated benefits will actually be realized.
Likewise, we cannot be sure that we will be able to obtain additional financing
for acquisitions. Such additional financing could be restricted by the terms of
our debt agreements.

     The process of integrating acquired operations, including our recent
acquisitions, into our existing operations may result in unforeseen operating
difficulties and may require significant financial and managerial resources
that would otherwise be available for the ongoing development or expansion of
our existing operations. Possible future acquisitions by L-3 could result in
the incurrence of additional debt, contingent liabilities and amortization
expenses related to goodwill and other intangible assets, all of which could
materially adversely affect our financial condition and operating results. We
consider and execute strategic acquisitions on an ongoing basis and may be
evaluating acquisitions or engaged in acquisition negotiations at any given
time. We have reached agreement or are in discussions regarding a number of
potential acquisition opportunities and expect to use borrowings


                                       14
<PAGE>

   
under our bank credit facilities to fund these transactions if we proceed with
them. If all of these potential acquisitions were consummated, they would
require us to use all or substantially all of our currently available borrowing
capacity in 1999 and perhaps seek additional borrowing capacity. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition -- Liquidity and Capital Resources".
    


WE RELY ON A SMALL NUMBER OF SIGNIFICANT CUSTOMERS


     Our sales come mainly from contracts with agencies of, and contractors to,
the U.S. government. For the nine-month period ended September 30, 1998, we had
approximately 300 contracts each with value exceeding $1.0 million for the U.S.
government. Pro forma sales for the nine-month period ended September 30, 1998
to the U.S. government, including sales through prime contractors, were $608.1
million, representing approximately 73% of our corresponding sales. Our largest
U.S. government program, a cost plus, sole source contract for support of the
U-2 program of the defense department, contributed approximately 7% of pro
forma sales for the nine-month period ended September 30, 1998. No other
program represented more than 5% of our pro forma sales for the nine-month
period ended September 30, 1998. The loss of all or a substantial portion of
sales to the U.S. government would have a material adverse effect on our income
and cash flow. See "Management's Discussion and Analysis of Results of
Operations and Financial Condition" and "Business -- Government Contracts".


     Our sales for the nine-month period ended September 30, 1998 to Lockheed
Martin were $51.1 million or approximately 7% of our total sales. The loss of
all or a substantial portion of such sales to Lockheed Martin would have a
material adverse effect on our income and cash flow.


OUR GOVERNMENT CONTRACTS ENTAIL CERTAIN RISKS


     The reduction in the U.S. defense budget in the early 1990s has caused
most defense-related government contractors to experience declining revenues,
increased pressure on operating margins and, in certain cases, net losses. Our
businesses taken as a whole have experienced a substantial decline in sales
during this period. A significant decline in U.S. military expenditures in the
future could materially adversely affect our sales and earnings. The loss or
significant cutback of a large program in which we participate could also
materially adversely affect our future sales and earnings and thus our ability
to meet our financial obligations.


     Companies engaged primarily in supplying defense-related equipment and
services to government agencies are subject to certain business risks peculiar
to the defense industry. These risks include the ability of the U.S. government
to:


    o  suspend us from receiving new contracts pending resolution of alleged
       violations of procurement laws or regulations;


    o  terminate existing contracts;


    o  audit our contract-related costs and fees, including allocated indirect
       costs; and


    o  control and potentially prohibit the export of our products.

                                       15
<PAGE>

     All of our U.S. government contracts are subject to termination by the
U.S. government either for its convenience or if the contractor defaults.
Termination for convenience provisions provide only for our recovery of costs
incurred or committed, settlement expenses and profit on work completed prior
to termination. Termination for default provisions provide for the contractor
to be liable for excess costs incurred by the U.S. government in procuring
undelivered items from another source. In addition to the right of the U.S.
government to terminate, U.S. government contracts are conditioned upon the
continuing approval by Congress of the necessary spending. Congress usually
appropriates funds for a given program on a fiscal-year basis even though
contract performance may take more than one year. Consequently, at the
beginning of a major program, the contract is usually partially funded, and
additional monies are normally committed to the contract only if, as and when
appropriations are made by Congress for future fiscal years. Foreign defense
contracts generally contain similar provisions relating to termination at the
convenience of the government.

     The U.S. government may review our costs and performance on their
contracts, as well as our accounting and general business practices. Based on
the results of such audits, the U.S. government may adjust our contract-related
costs and fees, including allocated indirect costs. In addition, under U.S.
government purchasing regulations, some of our costs, including certain
financing costs, goodwill, portions of research and development costs, and
certain marketing expenses may not be reimbursable under U.S. government
contracts. Further, as a government contractor, we are subject to
investigation, legal action and/or liability that would not apply to a
commercial company.

     We are also subject to risks associated with the following:

    o  the frequent need to bid on programs in advance of the completion of
       their design (which may result in unforeseen technological difficulties
       and/or cost overruns);

    o  the substantial time and effort required for relatively unproductive
       design and development;

    o  design complexity and rapid obsolescence; and

    o  the constant need for design improvement.

We obtain many of our U.S. government contracts through a competitive bidding
process. We cannot assure you that we will continue to win competitively
awarded contracts or that awarded contracts will generate sufficient sales to
result in profitability for L-3. See "Business -- Major Customers" and "--
Government Contracts".

     In addition to these U.S. government contract risks, many of our products
and systems require licenses from U.S. government agencies for export from the
United States, and some of our products are not permitted to be exported. We
cannot be sure of our ability to gain any licenses required to export our
products, and failure to receive required licenses could materially reduce our
ability to sell our products outside the United States.


OUR FIXED PRICE CONTRACTS ENTAIL CERTAIN RISKS

     We provide our products and services primarily through fixed price or cost
plus contracts. Fixed price contracts constituted approximately 71% of our pro
forma sales for the nine-month period ended September 30, 1998. We record sales
and profits on our long-term fixed price contracts by using the
percentage-of-completion methods of accounting. As a result, revisions made to
our estimates of revenues and profits are reflected in the period in which the
conditions that require such revisions become known and can be estimated. The
risks of long-term fixed price contracts include the difficulty of forecasting
costs and schedules, contract revenues that are related to performance in
accordance with contract specifications and the possibility of obsolescence in
connection with long-term procurements. Failure to anticipate technical
problems, estimate costs accurately or control costs during performance of a
fixed price contract may reduce our profitability or cause a loss. Although we
believe that adequate provisions for losses for our fixed price contracts are
reflected in our financial statements, as required under U.S. generally
accepted accounting principles, we cannot assure you that these estimates and
provisions are adequate or that losses on fixed price contracts will not occur
in the future.


                                       16

OUR OPERATIONS INVOLVE RAPIDLY EVOLVING PRODUCTS AND TECHNOLOGICAL CHANGE

     The rapid change of technology is a key feature of the communication
equipment industry for defense applications and in general. To succeed in the
future, we will need to design, develop, manufacture, assemble, test, market
and support new products and enhancements on a timely and cost-effective basis.
Historically, our technology has been developed through customer-sponsored
research and development as well as from internally-funded research and
development. We cannot guarantee that we will continue to maintain comparable
levels of research and development. See "Business -- Research and Development".
In the past we have allocated substantial funds to capital expenditures and
programs and other investments. This practice will continue to be required in
the future. See "Management's Discussion and Analysis of Results of Operations
and Financial Condition". Even so, we cannot assure you that we will
successfully identify new opportunities and continue to have the needed
financial resources to develop new products in a timely or cost-effective
manner. At the same time, products and technologies developed by others may
render our products and systems obsolete or non-competitive.


OUR ENTRY INTO COMMERCIAL BUSINESS IS RISKY

     Our revenues mainly have come from business with the U.S. defense
department and other government agencies. In addition to continuing to pursue
this major market area, we will continue applying our technical capabilities
and expertise to related commercial markets. Some of our commercial products,
such as local wireless loop telecommunications equipment, medical image
archiving equipment, airport security equipment and commercial information
security products, have only recently been introduced. As such, these new
products are subject to certain risks and may require us to:

      o  develop and maintain marketing, sales and customer support
         capabilities;

      o  secure sales and customer support capabilities;

      o  obtain certification;

      o  respond to rapid technological advances; and

      o  obtain customer acceptance of these products and product performance.

Our efforts to expand our presence in the commercial market may require
significant resources including capital and management time. We cannot assure
our success in addressing these risks or in developing these commercial
business opportunities.


WE OPERATE IN A COMPETITIVE INDUSTRY

     The communications equipment industry for defense applications and as a
whole is highly competitive. The defense industry has experienced substantial
consolidation due to declining defense budgets and increasing pressures for
cost reductions. We expect that the U.S. defense department's increased use of
commercial off-the-shelf products and components in military equipment will
encourage new competitors to enter the market. In addition, the consolidation
of the industry has resulted in delays in contract funding and awards and
significant pricing pressures. We also expect that competition for original
equipment manufacturer business will increase due to the emergence of merchant
suppliers. Our ability to compete for defense contracts largely depends on the
following factors:

      o  the effectiveness and innovations of our research and development
         programs;

      o  our ability to offer better performance than our competitors at a lower
         cost to the U.S. government; and

      o  the readiness of our facilities, equipment and personnel to undertake
         the programs for which we compete.


                                       17
<PAGE>

In some instances, programs are sole source or work directed by the U.S.
government to a single supplier. In such cases, other suppliers who may be able
to compete for the programs involved can only enter or reenter the market if
the U.S. government chooses to reopen the particular program to competition.
Many of our competitors are larger than us and have substantially greater
financial and other resources than we have. See "Business -- Competition".


WE DEPEND ON KEY PERSONNEL

     Our future success depends to a significant degree upon the continued
contributions of our management, including Messrs. Lanza and LaPenta, and our
ability to attract and retain other highly qualified management and technical
personnel. We do not maintain any key person life insurance policies for
members of our management. Messrs. Lanza and LaPenta have invested
approximately $18.0 million and currently own approximately 12.4% of the
capital stock of L-3. We have entered into employment agreements with Messrs.
Lanza and LaPenta. See "Management -- Employment Agreements". We face
competition for management and technical personnel from other companies and
organizations. Failure to attract and retain such personnel would damage our
prospects. See "Management -- Directors and Executive Officers".


OUR OPERATIONS ARE SUBJECT TO ENVIRONMENTAL REGULATION

     Our operations are subject to various federal, state and local
environmental laws and regulations relating to the discharge, storage,
treatment, handling, disposal and remediation of certain materials, substances
and wastes used in our operations. We continually assess our obligations and
compliance with these requirements. We believe that our operations are in
substantial compliance with all applicable environmental laws and permits. We
do not expect any material unbudgeted expenditures to remain in compliance with
applicable environmental laws and regulations.

     In connection with the purchase of the Company from Lockheed Martin, we
assumed certain environmental liabilities related to events or activities
occurring prior to the purchase. Lockheed Martin has agreed to retain all
environmental liabilities for all facilities no longer used by us and to
indemnify us fully for such liabilities. Lockheed Martin has also agreed, for
the first eight years following April 1997, to pay 50% of all costs incurred by
us above those reserved for our balance sheet at April 1997 relating to certain
environmental liabilities assumed by us. For the seven years thereafter,
Lockheed Martin has agreed to pay 40% of certain reasonable operation and
maintenance costs relating to any environmental remediation projects undertaken
in the first eight years. Two of the facilities acquired from Lockheed Martin
will require ongoing remediation due to environmental contamination. In
November 1997, we sold one such facility located in Sarasota, Florida, while
retaining a leasehold interest in a portion of that facility, to Dames &
Moore/Brookhill LLC, which agreed to assume responsibility for further
remediation of the Sarasota site. We believe that we have established adequate
reserves for the potential costs associated with the assumed environmental
liabilities. However, we cannot assure you that any costs incurred will be
reimbursable from the U.S. government or covered by Lockheed Martin under the
terms of the acquisition agreement or that our environmental reserves will be
sufficient.


OUR BACKLOG OF ORDERS COULD BE TERMINATED

     We currently have a backlog of orders, mainly under contracts with the
U.S. government. The U.S. government may unilaterally modify or terminate these
contracts. Accordingly, most of our backlog could be modified or terminated by
the U.S. government. We cannot assure you that our backlog will result in
revenues. Further, we cannot be sure that the margins on any contract included
in backlog that does become revenue will be profitable.


WE HAVE PENSION PLAN LIABILITIES

     We have assumed certain liabilities relating to defined benefit pension
plans for present and former employees and retirees of certain businesses which
we acquired. Prior to the L-3 Acquisition,


                                       18
<PAGE>

   
Lockheed Martin received a letter from the Pension Benefit Guaranty Corporation
(the "PBGC"), which requested information regarding the transfer of these
pension plans and indicated that the PBGC believed certain of these pension
plans were underfunded using the PBGC's actuarial assumptions. These
assumptions resulted in a larger liability for accrued benefits than the
assumptions used for financial reporting under Statement of Financial
Accounting Standards No. 87 ("FASB 87"). The PBGC underfunding is related to
the Communication Systems -- West and Aviation Recorders pension plans (the
"Subject Plans"). As of September 30, 1998 we calculated the net funding
position of these plans and believe them to be:
    

      o  overfunded by approximately $4.8 million under the assumptions set
         forth in the Employee Retirement Income Security Act of 1974, as
         amended;
       

      o  underfunded by approximately $28.4 million under FASB 87 assumptions;
         and

      o  underfunded by as much as $70.4 million under PBGC assumptions.

   
     L-3, Lockheed Martin and the PBGC entered into certain agreements dated as
of April 30, 1997 in which Lockheed Martin gave a commitment to the PBGC with
regard to the Subject Plans and L-3 gave certain assurances to Lockheed Martin
regarding these plans. In connection with these agreements, Lockheed Martin has
the option, upon 45 days prior written notice after the occurrence of certain
triggering events, to cause us to transfer sponsorship of the Subject Plans to
it if Lockheed Martin has concluded that the liabilities of the Subject Plans
would increase unreasonably. We have funded and acted in accordance with the
terms of our agreement with Lockheed Martin. As a result of a decrease in the
PBGC-mandated discount rate and the resulting increase in the underlying
liability, a triggering event has occurred. We have notified Lockheed Martin of
this fact. Lockheed Martin has informed us that it has no present intention to
exercise its right to cause us to transfer sponsorship of the Subject Plans. If
Lockheed Martin did assume sponsorship of the Subject Plans, it would be
primarily liable for the costs associated with funding these plans or any costs
associated with the termination of the Subject Plans, but we would be required
to reimburse Lockheed Martin for these costs. See "Business -- Pension Plans".
To date, the impact on pension expense and funding requirements resulting from
this arrangement has not been significant. However, should Lockheed Martin
assume sponsorship of the Subject Plans or if these were terminated, the impact
of any increased pension expenses or funding requirements could be material to
us.
    


WE HAVE DISCRETION OVER THE USE OF FUNDS RAISED IN THE OLD NOTES OFFERING

   
     We used the net proceeds of the Old Notes Offering to repay a substantial
portion of our debt under our bank credit facilities. Our borrowing capacity
has been restored and we have wide discretion over the use of any funds
subsequently reborrowed under our bank credit facilities. We have borrowed
approximately $50.0 million under our bank credit facilities to fund the
acquisition of Microdyne.
    


OUR DEBT AGREEMENTS CONTAIN RESTRICTIONS

     Our debt agreements contain a number of significant provisions that, among
other things, restrict our ability to:

      o  sell assets;

      o  incur more indebtedness;

      o  repay certain indebtedness;

      o  pay dividends;

      o  make certain investments or acquisitions;

      o  repurchase or redeem capital stock;

      o  engage in mergers or consolidations; and

      o  engage in certain transactions with subsidiaries and affiliates.

                                       19
<PAGE>

     These restrictions could hurt our ability to finance our future operations
or capital needs or engage in other business activities that may be in our
interest. In addition, certain of our debt agreements also require us to
maintain compliance with certain financial ratios, including total consolidated
earnings before interest, taxes, depreciation and amortization to total
consolidated cash interest expense and net debt to total consolidated earnings
before interest, taxes, depreciation and amortization, and to limit our capital
expenditures. Our ability to comply with these ratios and limits may be
affected by events beyond our control. A breach of any of these agreements or
our inability to comply with the required financial ratios or limits could
result in a default under those debt agreements. In the event of any such
default, the lenders under those debt agreements could elect to:

      o  declare all debt outstanding, accrued interest and fees to be due and
         payable;

      o  require us to apply all of our available cash to repay the debt; and


      o  prevent us from making debt service payments on other debt.

     If we were unable to repay any such borrowings when due, the lenders under
our bank credit facilities could proceed against their collateral, which
includes a first priority lien on substantially all of our assets and a first
priority security interest in all of our capital stock and the capital stock of
our subsidiaries. If the indebtedness under the existing debt agreements were
to be accelerated, we cannot assure you that our assets would be sufficient to
repay such indebtedness in full. See "Description of Certain Indebtedness".



NOT ALL OF OUR SUBSIDIARIES ARE GUARANTORS

     Most but not all of our subsidiaries will guarantee the notes. In the
event of a bankruptcy, liquidation or reorganization of any of the
non-guarantor subsidiaries, holders of their indebtedness and their trade
creditors will generally be entitled to payment of their claims from the assets
of those subsidiaries before any assets are made available for distribution to
us. Assuming we had completed the Old Notes Offering and the exchange of the
Exchange Notes on September 30, 1998, these Notes would have been effectively
junior to $9.6 million of indebtedness and other liabilities (including trade
payables) of these non-guarantor subsidiaries. The non-guarantor subsidiaries
generated less than one percent of each of our historical consolidated
revenues, net income and cash from operating activities for the twelve-month
period ended September 30, 1998, and held 2% of our consolidated assets as of
September 30, 1998.



WE ARE REQUIRED TO TAKE CERTAIN ACTIONS UPON A CHANGE OF CONTROL

     Upon the occurrence of certain specific kinds of change of control events,
we will be required to offer to repurchase all outstanding Notes. However, it
is possible that we will not have sufficient funds at the time of the change of
control to make the required repurchase of Notes or that restrictions in our
bank credit facilities will not allow such repurchases. In addition, certain
important corporate events, such as leveraged recapitalizations that would
increase the level of our indebtedness, would not constitute a "Change of
Control" under the indenture governing the Notes. See "Description of the
Exchange Notes--Repurchase at the Option of Holders".



THIS PROSPECTUS CONTAINS FORWARD LOOKING STATEMENTS

     Certain of the matters discussed concerning our operations, economic
performance and financial condition, including in particular, the likelihood of
our success in developing and expanding our business and the realization of
sales from backlog, include forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act.
Statements that are predictive in nature, that depend upon or refer to future
events or conditions or that include words such as "expects", "anticipates",
"intends", "plans", "believes", "estimates" and similar expressions are
forward-looking statements. Although we believe that these statements are based
upon reasonable assumptions, we can give no assurance that their goals will be
achieved.

OUR YEAR 2000 COMPLIANCE EFFORTS WILL REQUIRE SUBSTANTIAL RESOURCES AND FAILURE
BY US OR CERTAIN THIRD PARTIES TO BE YEAR 2000 COMPLIANT POSES CERTAIN RISKS


     The inability of business processes to continue to function correctly
after the beginning of the Year 2000 could have serious adverse effects on
companies and entities throughout the world.
Because our business units operate autonomously, each business unit has
undertaken an effort to identify and mitigate Year 2000 issues in their
information systems, products, facilities, suppliers and customers. Our Year
2000 compliance efforts are a composite of our business units' individual Year
2000 compliance efforts coordinated through a company-wide program instituted
to oversee, guide and track our business units' individual Year 2000 compliance
efforts and to facilitate communications between business units regarding Year
2000 compliance methods. Our business operations are also dependent on the Year
2000 readiness of our customers and infrastructure suppliers in areas such as
utilities, communications, transportation and other services.


     Each business unit has appointed a Year 2000 project manager who oversees
a team responsible for performing its Year 2000 efforts in four phases:


      o  first, to define, identify and list possible sources of Year 2000
         issues, including internal systems and products and services sold to
         customers;


      o  second, to analyze and determine the nature and extent of Year 2000
         issues and to develop project plans to address those issues;


      o  third, to implement and execute project plans to fix or replace
         non-compliant items, as appropriate, based upon the anticipated risk
         and its importance; and


      o  fourth, to commence and complete testing, continue monitoring readiness
         and prepare necessary contingency plans.


     The progress of this program is monitored at each business unit with
oversight by management. This oversight includes periodic reviews as well as
visits to each business unit to monitor progress
with the plans. Management plans to have completed the first three phases of
the program for a substantial majority of mission-critical systems within L-3
by the end of March 1999 and to have nearly all significant information
systems, products and facilities in the final phase of the program by mid-1999.
 


     Our total costs associated with our internal Year 2000 compliance efforts
are estimated to be $16.2 million, including $7.1 million of costs which may be
capitalized with the remaining costs expensed as incurred. We have incurred
approximately $6.6 million of such costs to date. Substantially all of the
remaining estimated costs are expected to be incurred in 1999. We cannot assure
you that our Year 2000 compliance efforts will be successful or that we will
not incur substantial costs as a result of failure of our customers or
suppliers to be Year 2000 compliant or as a result of failures of installed
products produced by us or for any other reason.

                                USE OF PROCEEDS


     There will be no proceeds to the Company from the exchange of Notes
pursuant to the Exchange Offer.


     The net proceeds to the Company from the Old Notes Offering, approximately
$193.7 million, after deducting the bond discount, underwriting discounts and
commissions and other estimated offering expenses which aggregated $7.2
million, were used to repay the outstanding borrowings under the Senior Credit
Facilities (as defined later in this prospectus) and increase the Company's
cash balance.

if it had occurred on September 30, 1998. See "Use of Proceeds" and "Unaudited
Pro Forma Condensed Consolidated Financial Information".

(1)   Borrowings under the Senior Credit Facilities outstanding as of September
      30, 1998 were repaid with the proceeds of the Notes Offering.
      Availability under the Senior Credit Facilities at any given time is
      $385.0 million (subject to compliance with covenants), less the amount of
      outstanding borrowings and outstanding letters of credit (which amounted
      to $58.0 million at December 31, 1998).
    



PROPOSED EQUITY OFFERING


     Holdings and certain selling stockholders are currently contemplating the
Proposed Equity Offering. It is intended that Holdings would use the net
proceeds of the Proposed Equity Offering to repay the existing indebtedness
under the Senior Credit Facilities and for general corporate purposes,
including potential acquisitions. On January 5, 1999, Holdings filed a
Registration Statement on Form S-1 (File No. 333--70125) with the SEC in
connection with the Proposed Equity Offering.

       UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION


   
     The following unaudited pro forma statement of operations data gives
effect to the following transactions (collectively, the "Transactions") as if
they had occurred on January 1, 1997: (i) the Old Notes Offering; (ii) the
Company's purchase of all of the outstanding stock of SPD and the acquisitions
by the Company of the assets of the Ocean Systems business ("Ocean Systems") of
Allied Signal, Inc., the assets of ILEX Systems ("ILEX") and the assets of the
Satellite Transmission Systems division ("STS") of California Microwave, Inc.
(collectively, the "1998 Acquisitions"); (iii) the L-3 Acquisition; and (iv)
the contribution by Holdings to the Company of the net proceeds from its common
stock initial public offering which amounted to $139.5 million and the sale by
the Company of $180.0 million of 81/2% Senior Subordinated Notes due May 15,
2008 whose net proceeds amounted to $173.8 million after debt issuance costs,
and the amendment of the Company's Senior Credit Facilities to increase the
available borrowings under the bank credit facilities to $385.0 million
(collectively, the "Financing Transactions"). The pro forma balance sheet data
gives effect to the Old Notes Offering as if it had occurred on September 30,
1998. The pro forma financial information is based on (i) the unaudited
condensed consolidated financial statements of the Company as of September 30,
1998 and for the nine months then ended and the six months ended September 30,
1997, (ii) the consolidated statement of operations of the Company for the nine
months ended December 31, 1997, (iii) the combined statement of operations of
the Predecessor Company for the three months ended March 31, 1997 and (iv) the
statements of operations of the 1998 Acquisitions for the year ended December
31, 1997 and the nine months ended September 30, 1997 and for the periods from
January 1, 1998 to the respective dates of acquisition, using the purchase
method of accounting and the assumptions and adjustments in the accompanying
notes to the unaudited pro forma condensed consolidated financial statements.
The pro forma results do not give effect to the Proposed Equity Offering or to
any of the Company's other acquisitions, including the acquisition of
Microdyne.
    


     The pro forma adjustments are based upon preliminary estimates of purchase
prices and the related purchase price allocations for the 1998 Acquisitions.
Actual adjustments will be based on final appraisals and other analyses of fair
values which are in process. Management does not expect that differences
between the preliminary and final allocations will have a material impact on
the Company's pro forma financial position or results of operations. The pro
forma statement of operations does not reflect any cost savings that management
of the Company believes would have resulted had the Transactions occurred on
January 1, 1997. The pro forma financial information should be read in
conjunction with (i) the unaudited condensed (combined) consolidated financial
statements of the Company as of September 30, 1998, for the nine months ended
September 30, 1998 and the six months ended September 30, 1997, (ii) the
audited consolidated financial statements of SPD for the year ended December
31, 1997, (iii) the unaudited condensed consolidated statements of operations
of SPD for the six months ended June 30, 1998, (iv) the audited consolidated
(combined) financial statements of the Company and the Predecessor Company as
of December 31, 1997 and for the nine months ended December 31, 1997 and the
three months ended March 31, 1997, (v) the audited financial statements of STS
for the year ended June 30, 1997, (vi) the unaudited condensed financial
statements of STS as of December 31, 1997 and for the six months ended December
31, 1997 and 1996, (vii) the audited consolidated financial statements of ILEX
for the year ended December 31, 1997, and (viii) the audited combined financial
statements of Ocean Systems for the year ended December 31, 1997 all of which
are included elsewhere herein in this prospectus. The unaudited pro forma
condensed financial information may not be indicative of the financial position
and results of operations of the Company that actually would have occurred had
the Transactions been in effect on the dates indicated or the financial
position and results of operations that may be obtained in the future.

   NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


     The following facts and assumptions were used in determining the pro forma
effect of the Transactions.


1.  The Company's historical financial statements reflect the results of
    operations of the Company since the effective date of the L-3 Acquisition,
    April 1, 1997, and the Predecessor Company's historical financial
    statements reflect the results of operations of the Predecessor Company
    for the three months ended March 31, 1997. The adjustments made to the pro
    forma statement of operations for the six months ended September 30, 1997
    and for the year ended December 31, 1997, relating to the L-3 Acquisition
    are: (a) the elimination of $1.8 million of sales and $1.8 million of
    costs and expenses related to the Hycor business which was acquired as
    part of the L-3 Acquisition and which has been accounted for as "net
    assets of acquired business held for sale"; (b) a reduction to costs and
    expenses of $0.8 million to record amortization expenses on the excess of
    the L-3 Acquisition purchase price over net assets acquired of $303.2
    million over 40 years, net of the reversal of amortization expenses of
    intangibles included in the Predecessor Company historical financial
    statements; (c) a reduction to costs and expenses of $0.6 million to
    record estimated pension cost on a separate company basis net of the
    reversal of the allocated pension cost included in the Predecessor Company
    historical financial statements; (d) a net increase to interest expense of
    $1.5 million, comprised of a $0.2 million allocated interest expense
    reduction related to the Hycor business and a net $1.7 million increase,
    reflecting pro forma interest expense of $10.2 million based on actual
    borrowings of $400.0 million and the effective cost of borrowing rate
    incurred by the Company to finance the L-3 Acquisition less interest
    expense of approximately $8.5 million included in the historical financial
    statements of the Predecessor Company; and (e) the reversal of a $4.4
    million noncash compensation charge related to the initial capitalization
    of the Company included in the Company's historical results of operations
    effective April 1, 1997 which was nonrecurring in nature. A statutory
    (federal, state and foreign) tax rate of 39.0% was assumed on these pro
    forma adjustments except for adjustment (e), where no tax effect has been
    reflected.


2.  On August 13, 1998, the Company acquired 100% of the stock of SPD for $230.0
    million of cash, subject to adjustment based on closing adjusted net
    assets, as defined. For purposes of the pro forma financial information an
    estimated purchase price of $241.1 million, including expenses (net of
    cash acquired of $0.2 million) was assumed reflecting the contract price
    of $230.0 million and an estimated purchase price adjustment of $11.0
    million based on the estimated closing adjusted net assets of SPD. On
    February 5, 1998, the Company purchased the assets of STS for $27.0
    million of cash subject to adjustment based on final closing net assets.
    For purposes of the pro forma financial information an estimated purchase
    price of $26.2 million including expenses (net of cash acquired of $0.5
    million) was assumed reflecting the contract price of $27.0 million and an
    estimated purchase price reduction of $1.0 million based on the estimated
    closing net assets of STS. On March 4, 1998, the Company purchased
    substantially all the assets of ILEX for $51.9 million of cash, subject to
    adjustment based on closing net assets plus additional consideration
    contingent upon post-acquisition performance of ILEX. For purposes of the
    pro forma financial information an estimated purchase price of $51.5
    million, including expenses (net of cash acquired of $2.4 million) was
    assumed reflecting the contract price of $51.9 million and a purchase
    price adjustment of $1.2 million based on final closing net assets, On
    March 30, 1998, the Company purchased the assets of Ocean Systems for
    $68.6 million of cash including expenses.


   The aggregate purchase prices including expenses, net of cash acquired, for
   the 1998 Acquisitions of $387.4 million were financed with $142.3 million
   of the net proceeds from the Financing Transactions (see Note 6 below),
   $155.0 million of borrowings under the Senior Credit Facilities and $90.1
   million of cash from operations. The 1998 Acquisitions are all included in
   the Company's historical balance sheet as of September 30, 1998.

4.  The aggregate estimated excess of purchase price, including expenses, over
    the estimated fair value of net assets acquired related to the 1998
    Acquisitions of $302.7 million is comprised of $205.1 million, $38.6
    million and $59.0 million, respectively, for SPD, ILEX and Ocean Systems,
    and is being amortized over 40 years resulting in a charge of $7.6 million
    per annum. Based upon preliminary estimates of fair value, the acquisition
    of STS resulted in no goodwill being recorded since the purchase price was
    equal to the fair value of net assets acquired. The preliminary purchase
    price allocation for SPD also includes an adjustment of $5.0 million to
    intangible assets to reflect the estimated value of acquired identifiable
    intangibles which are being amortized over 15 years resulting in a change
    of $0.3 million per annum.

    Adjustments to costs and expenses in the pro forma statements of operations
    relating to the 1998 Acquisitions were comprised of the following:

   The preliminary purchase price allocations for SPD and Ocean Systems include
   estimated increases to contracts in process of $2.0 million and $3.4
   million, respectively, related to valuing certain work-in-process and
   finished goods inventory at their fair values. In addition, the
   preliminary purchase price allocation for Ocean Systems includes an
   estimated $5.1 million adjustment relating to a reduction of contracts in
   process resulting from valuing acquired contracts in process at contract
   price, less the estimated cost to complete and an allowance for normal
   profit margin on the Company's effort to complete such contracts. The
   non-recurring charges to income resulting from the above mentioned
   contracts in process adjustment are not material to the pro forma
   statement of operations. The effects on the balance sheet of these
   adjustments are included in the historical balance sheet of the Company
   as of September 30, 1998.

6.  The Financing Transactions included (i) the contribution by Holdings to the
    Company of the proceeds from its sale of 6.9 million shares of common
    stock in the IPO for $22 per share or $139.5 million, after underwriting
    discounts and commissions and expenses of $12.3 million, (ii) the sale by
    the Company of $180.0 million aggregate principal amount of 8 1/2% Senior
    Subordinated Notes due May 15, 2008 (the "May 1998 Notes"), whose proceeds
    amounted to $173.8 million after debt issuance costs of $6.2 million and
    (iii) the amendment of the Company's Senior Credit Facilities to increase
    the borrowings available thereunder to $385.0 million from $200.0 million.
    The net proceeds from the Financing Transactions of $313.3 million have
    been used to (i) prepay all $171.0 million of borrowings outstanding under
    the term loan facilities and (ii) finance $142.3 million of the aggregate
    purchase prices of the 1998 Acquisitions (see Note 2 above). The Holdings
    IPO and the sale of the May 1998 Notes were completed on May 22, 1998 and
    the amendment to the Senior Credit Facilities was completed on August 19,
    1998. The effect of the Financing Transactions is included in the
    Company's historical balance sheet as of September 30, 1998.

7.  Adjustments to the pro forma statements of operations for the Financing
    Transactions include the elimination of historical interest income of $2.3
    million, $0.6 million and $1.3 million for the nine months ended September
    30, 1998 and 1997 and the year ended December 31, 1997, respectively, to
    reflect the use of cash on hand to partially finance the aggregate
    purchase price of the 1998 Acquisitions.

    proceeds of the Old Notes, (ii) an increase of $7.2 million to other
    assets representing the bond discount of $0.6 million and underwriting

    interest expense over the term of the Notes and (iii) an increase to cash
    and cash equivalents of $37.8 million representing the remaining net

(1)  Includes the results of operations of the 1998 Acquisitions from their
     respective effective dates of acquisition.

(2)  Reflects the L-3 Acquisition effective April 1, 1997.

(3)  Reflects ownership of Loral's Communication Systems -- West and Specialized
     Communication Products businesses commencing April 1, 1996.

(4)  Reflects ownership of Communication Systems -- East by Lockheed Martin
     effective April 1, 1993.

(5)  Reflects ownership of Communications Systems -- East by GE Aerospace. The
     amounts shown herein include only those amounts as reflected in the
     financial records of Communications Systems -- East.

(6)  Includes a nonrecurring, noncash compensation charge of $4.4 million
     related to the initial capitalization of the Company, effective April 1,
     1997.

(7)  For periods prior to April 1, 1997, interest expense and income tax
     (benefit) provision were allocated from Lockheed Martin.

(8)  EBITDA is defined as operating income plus depreciation expense and
     amortization expense (excluding the amortization of deferred debt issuance
     costs) and the nonrecurring, noncash compensation charge of $4.4 million
     recorded on April 1, 1997. EBITDA is not a substitute for operating income,
     net income and cash flow from operating activities as determined in
     accordance with generally accepted accounting principles as a measure of
     profitability or liquidity. EBITDA is presented as additional information
     because management believes it to be a useful indicator of the Company's
     ability to meet debt service and capital expenditure requirements.

(9)  For purposes of this computation, earnings consist of income before income
     taxes plus fixed charges. Fixed charges consist of interest on indebtedness
     plus the amortization of deferred debt issuance costs and that portion of
     lease rental expense representative of the interest element.

(10) Earnings were insufficient to cover fixed charges by $0.5 million for the
     three months ended March 31, 1997.

(11) For purposes of this computation, cash interest expense consists of pro
     forma interest expense excluding amortization of deferred debt issuance
     costs.

(12) The ratios at September 30, 1998 are based on the results of operations for
     the twelve-month period ended September, 1998. The pro forma ratios at
     September 30, 1998 have been calculated by adding the pro forma EBITDA and
     pro forma cash interest expense for the nine months ended September 30,
     1998 and the three months ended December 31, 1997. For purposes of
     computing pro forma EBITDA for the three months ended December 31, 1997,
     pro forma operating income, depreciation expense and amortization expense
     would have been $32.9 million, $6.3 million and $6.7 million, respectively.
     Pro forma cash interest expense for the twelve-month period ended September
     30, 1998 and the year ended December 31, 1997 both would have been $56.1
     million.

(13) Net debt is defined as long-term debt plus current portion of long-term
     debt less cash and cash equivalents.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION


GENERAL

     The Company is a leading merchant supplier of sophisticated secure
communication systems and specialized communication products including secure,
high data rate communication systems, microwave components, avionics and ocean
systems, telemetry, instrumentation and space products. These systems and
products are critical elements of virtually all major communication, command
and control, intelligence gathering and space systems. The Company's systems
and specialized products are used to connect a variety of airborne, space,
ground-and sea-based communication systems and are incorporated into the
transmission, processing, recording, monitoring and dissemination functions of
these communication systems. The Company's customers include the United States
department of defense (the "DoD"), selected United States government (the
"Government") intelligence agencies, major aerospace/defense prime contractors,
foreign governments and commercial customers.

     All domestic government contracts and subcontracts of the Company are
subject to audit and various cost controls, and include standard provisions for
termination for the convenience of the Government. Multi-year Government
contracts and related orders are subject to cancellation if funds for contract
performance for any subsequent year become unavailable. Foreign government
contracts generally include comparable provisions relating to termination for
the convenience of the relevant foreign government.

     The defense industry has undergone significant changes precipitated by
ongoing federal budget pressures and new roles and missions to reflect changing
strategic and tactical threats. Since the mid-1980's, the overall U.S. defense
budget has declined in real dollars. In response, the DoD has focused its
resources on enhancing its military readiness, joint operations and the
value-added capability of digital command and control communications by
incorporating advanced electronics to improve the performance, reduce operating
costs and extend the life expectancy of its existing and future platforms. The
emphasis on system interoperability, force multipliers and providing
battlefield commanders with real-time data is increasing the electronics
content of nearly all of the major military procurement and research programs.
As a result, the DoD's budget for communications and defense electronics is
expected to grow.


 ACQUISITION HISTORY/RECENT DEVELOPMENTS

     The Company was formed to acquire substantially all of the assets of (i)
nine business units previously purchased by Lockheed Martin as part of its
acquisition of Loral in April 1996 (the "Loral Acquired Businesses") which
include eight business units of Loral ("Specialized Communications Products")
and one business unit purchased by Loral as part of its acquisition of the
Defense Systems business of Unisys Corporation ("Unisys") in May 1995
("Communications System -- West"), and (ii) one business unit purchased by
Lockheed Martin as part of its acquisition of the aerospace business of General
Electric Company in April 1993 ("Communication Systems -- East"). Collectively,
the Loral Acquired Businesses and Communications Systems -- East comprise the
"Predecessor Company" or "Businesses".

     During the first quarter of 1998, the Company purchased the assets of
Ocean Systems for $67.5 million of cash, the assets of ILEX for $51.9 million
of cash, subject to adjustment based on closing net assets and additional
consideration based on post-acquisition performance of ILEX, and the assets of
STS for $27.0 million in cash, subject to adjustment based upon closing net
assets.

     SPD Technologies, Inc. On August 13, 1998, the Company acquired all of the
outstanding common stock of SPD for $230.0 million in cash, subject to certain
post-closing adjustments. SPD is the major supplier to the United States Navy
for subsystems that manage, control, distribute, protect and condition
electrical power in surface ships and submarines. SPD's major products include
electronic solid state protection products, switchgear, high-speed transfer
switches, fault isolation units, frequency converters and inverters, voltage
transformers and uninterruptible power supply systems.


                                       36
<PAGE>

SPD's products are installed in every nuclear submarine, aircraft carrier and
surface platform operated by the United States Navy. SPD also provides
shipboard communications and control as well as support service for installed
products. The acquisition was financed using cash from operations and
borrowings under the Senior Credit Facilities.

     Other Acquisitions. Additionally, during the nine months ended September
30, 1998, the Company purchased five other companies for an aggregate purchase
price of $24.8 million of cash, before adjustments, as appropriate, based on
closing date net assets and additional consideration based on post-acquisition
performance. The historical impact of these five other acquisitions
individually or in the aggregate was not material to the results of operations
or financial position of the Company.

   
     On November 12, 1998, L-3 Communications acquired all of the outstanding
stock of DBS Microwave, Inc. ("DBS") for $13.0 million of cash, of which $3.0
million was paid prior to September 30, 1998 subject to adjustment based on
closing net assets, as defined. The acquisition was financed with borrowings
under the Senior Credit Facilities.
    

     On December 17, 1998, the Company acquired all of the outstanding stock of
Electrodynamics Inc. from Carpenter Technology Corporation for $21.5 million in
cash, subject to adjustment based on closing net assets, as defined. The
acquisition was financed by cash on hand and with borrowings under the Senior
Credit Facilities.

   
     Microdyne Corporation. On December 3, 1998, the Company signed an
agreement to acquire all of the outstanding common stock of Microdyne for
approximately $90.0 million in cash, including the repayment of Microdyne's
debt. Pursuant to the acquisition agreement, a subsidiary of L-3 Communications
has purchased 91.9% of the common stock of Microdyne in a cash tender offer. We
expect to complete the merger of Microdyne with this subsidiary in early 1999.
Microdyne is a leading global developer and manufacturer of aerospace telemetry
receivers, secure communications and technical support services, including
specialized telemetry high-frequency radios used in aerospace and satellite
communications for data gathering and analysis. Microdyne also provides
products for the government and commercial signal intelligence markets and
support and repair services for electronic products companies. Microdyne's
aerospace telemetry products will enable us to provide integrated solutions to
our space customers' requirements for command, control, telemetry and tracking.
The purchase of shares of Microdyne common stock was financed using available
cash and borrowings under the Senior Credit Facilities. See "--Liquidity and
Capital Resources".
    


RESULTS OF OPERATIONS

     The following information should be read in conjunction with the Company's
Condensed Consolidated Financial Statements and Consolidated (Combined)
Financial Statements and the notes thereto included in this prospectus, which
reflect the Company's results of operations from the effective date of the L-3
Acquisition, April 1, 1997, and also include the results of operations of SPD,
Ocean Systems, ILEX and STS from the respective effective dates of each of
those acquisitions. Accordingly, the results of operations presented below
exclude the results of operations of the 1998 Acquisitions for periods prior to
their effective dates.

     The financial statements also reflect the results of operations of the
Predecessor Company for the three months ended March 31, 1997 and the years
ended December 31, 1996 and 1995, which include the results of operations of
the Loral Acquired Businesses beginning on April 1, 1996, the effective date of
that acquisition by the Predecessor Company. The results of operations for the
year ended December 31, 1996 include the results of operations of the Loral
Acquired Businesses for the nine months from April 1, 1996 to December 31,
1996. The results of operations for the year ended December 31, 1995 and the
period from January 1 to March 31, 1996 only comprise the results of operations
of Communications Systems -- East. Accordingly, changes between (i) the nine
months ended September 30, 1998 and the nine months ended September 30, 1997,
(ii) the year ended December 31, 1997 and the year ended December 31, 1996 and
(iii) the year ended December 31, 1996 and the year ended December 31, 1995 are
significantly affected by the timings of the 1998


                                       37
<PAGE>

Acquisitions, L-3 Acquisition and Loral Acquired Businesses acquisition.
Furthermore, operating income of the Company and the Predecessor Company are
not directly comparable between periods indicated as a result of the effects of
valuation of assets and liabilities recorded in accordance with Accounting
Principles Board Opinion No. 16 ("APB 16") by the Company and the Predecessor
Company for the purchase accounting of the L-3 Acquisition and Loral Acquired
Businesses acquisition. Interest expense and income taxes expense for the
periods are also not comparable and the impact of interest expense and income
tax expense on the Company is discussed below.

     The results of operations of the Predecessor Company for the three months
ended March 31, 1997 and the years ended December 31, 1996 and 1995, include
certain costs and expenses allocated by Lockheed Martin for corporate office
expenses based primarily on the allocation methodology prescribed by government
regulations pertaining to government contractors. Interest expense was
allocated based on Lockheed Martin's actual weighted average consolidated
interest rate applied to the portion of the beginning of the year invested
equity deemed to be financed by consolidated debt based on Lockheed Martin's
debt to equity ratio on such date. The provision (benefit) for income taxes was
allocated to the Predecessor Company as if it were a separate taxpayer,
calculated by applying statutory rates to reported pre-tax income after
considering items that do not enter into the determination of taxable income
and tax credits related to the Predecessor Company. Also, pension and
post-employment benefit costs were allocated based on employee headcount.
Accordingly, the results of operations and financial position hereinafter of
the Predecessor Company may not be the same as would have occurred had the
Predecessor Company been an independent entity.

 NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER
 30, 1997

     The results of operations for the nine months ended September 30, 1997
(the "1997 Nine-Month Period") were obtained by combining, without adjustment,
the historical results of operations of the Predecessor Company for the three
months ended March 31, 1997 with the historical results of operations of the
Company for the six-month period ended September 30, 1997. Changes between
periods for the nine months ended September 30, 1998 (the "1998 Nine-Month
Period") and the 1997 Nine-Month Period are affected by the timing of the L-3
Acquisition and the 1998 Acquisitions.

     The following table sets forth selected income statement data for the
Company and the Predecessor Company for the periods indicated.

(1)   EBITDA is defined as operating income plus depreciation expense and
      amortization expense (excluding the amortization of debt issuance costs)
      and the nonrecurring, noncash compensation charge. EBITDA is not a
      substitute for operating income, net income or cash flows from operating
      activities as determined in accordance with generally accepted accounting
      principles as a measure of profitability or liquidity. EBITDA is
      presented as additional information because the Company believes it to be
      a useful indicator of the Company's ability to meet debt service and
      capital expenditure requirements.


     Sales increased by $206.6 million to $708.3 million for the 1998
Nine-Month Period from $501.7 million for the 1997 Nine-Month Period. Operating
income for the 1998 Nine-Month Period increased by $27.1 million to $63.6
million from $36.5 million in the 1997 Nine-Month Period. Net income increased
by $15.0 million to $18.7 million from $3.7 million in the 1997 Nine-Month
Period.


                                       38
<PAGE>

     The 1998 Acquisitions contributed sales of $166.1 million to the 1998
Nine-Month Period. The remaining increase during the 1998 Nine-Month Period was
primarily attributable to an increase in production and shipments on the CHBDL,
Raptor and UAV programs and increased sales volumes on STE, aviation recorders,
display systems and RF safety and monitoring products, partially offset by
lower sales volume on commercial telecommunications products. Sales for the
1997 Nine-Month Period also included $1.8 million of sales from the Hycor
business which was sold in 1997 (see Note 6 to the Consolidated (Combined)
Financial Statements as of December 31, 1997).


     Operating income as a percentage of sales ("operating margin") increased
to 9.0% for the 1998 Nine-Month Period from 7.3% for the 1997 Nine-Month
Period. The increase in operating income for the 1998 Nine-Month Period is
principally attributable to (i) improved margins on sales of space
communications and military communication systems, aviation recorders and
display systems and increased sales volume on higher margin RF safety and
monitoring products, partially offset by lower sales volume on commercial
telecommunications products and lower margins from the STS acquired business,
(ii) the negative impact on operating income for the 1997 Nine-Month Period
from the non-recurring, noncash compensation charge of $4.4 million recorded
effective April 1, 1997, related to the initial capitalization of the Company
and (iii) losses incurred during the 1997 Nine-Month Period by the Predecessor
Company on three programs at Communication Systems -- East. The 1998
Acquisitions contributed $10.1 million of operating income to the 1998
Nine-Month Period. Excluding the non-recurring, noncash compensation charge,
operating margin for the 1997 Nine-Month Period was 8.2%.


     EBITDA for the 1998 Nine-Month Period increased by $28.5 million to $90.3
million from $61.8 million in the 1997 Nine-Month Period. EBITDA as a
percentage of sales ("EBITDA margin") increased to 12.7% for the 1998
Nine-Month Period from 12.3% for the 1997 Nine-Month Period. The increases in
EBITDA and EBITDA margin were primarily attributable to the items affecting the
trends in operating income between the 1998 Nine-Month Period and the 1997
Nine-Month Period discussed above, excluding the non-recurring, noncash
compensation charge which is not included in EBITDA.


     Interest expense, net for the Company for the 1998 Nine-Month Period was
$32.9 million, compared to $27.6 million in the 1997 Nine-Month Period for the
Company and the Predecessor Company combined. The increase was attributable to
higher average outstanding debt balances during the 1998 Nine-Month Period,
partially offset by higher interest income for the 1998 Nine-Month Period.


     The effective income tax rate of the Company for the 1998 Nine-Month
Period was 39.1%, reflecting the estimated effective income tax rate for the
year ended December 31, 1998. The effective tax rate for the 1997 Nine-Month
Period for the Company and the Predecessor Company combined was 58.0%, and was
significantly impacted by the $4.4 million non-recurring, noncash compensation
charge recorded effective April 1, 1997 and the Predecessor Company's
amortization of costs in excess of net assets acquired for the three months
ended March 31, 1997, both of which were not deductible for income tax
purposes.

</TABLE>

     Sales for the nine months ended December 31, 1997 as compared to the
corresponding period in 1996 increased by $44.6 million, of which $30.5 million
is attributable to the Loral Acquired Businesses and $14.1 million to
Communication Systems -- East. The increase in sales is attributable to
increased volume in sales of microwave components, CHBDL, UAV programs, F-14
display system contract, power supplies and P3-C Repair Depot.

     Operating income for the nine months ended December 31, 1997 as compared
to the corresponding period in 1996 increased by $9.5 million. The net increase
was comprised of increases of $5.8 million attributable to the Loral Acquired
Businesses and $8.1 million to Communication Systems -- East, partially offset
by a nonrecurring, noncash compensation charge of $4.4 million recorded
effective April 1, 1997, related to the initial capitalization of L-3. The
increase in operating income for the nine months ended December 31, 1997 is
attributable to increased sales, improved operating performance on sales of
aviation recorders, passive microwave components and display systems, the
GEMnet product-line and P3-C Repair Depot sales, partially offset by $3.3
million of cost of sales related to ongoing certification efforts for the
Company's Explosive Detection System ("EDS") contract and lower sales volume on
the U-2 Program.

     Sales and operating income for the three months ended March 31, 1997
increased by $117.7 million and $6.2 million, respectively, as compared to the
corresponding period in 1996. The increases are attributable to the acquisition
of the Loral Acquired Businesses, offset by losses incurred on three programs
by Communication Systems -- East.

     Sales and operating income of the Hycor business which was sold in 1997
for the three months ended March 31, 1997 and the year ended December 31, 1996
were $1.8 million and $0.0 million and $7.5 million and $0.3 million,
respectively (see Note 6 to the Consolidated (Combined) Financial Statements).

     Interest expense, net for the nine months ended December 31, 1997 was
$28.5 million representing interest expense on the Company's outstanding
borrowings (see Note 8 to Consolidated (Combined) Financial Statements as of
December 31, 1997), and amortization of debt issuance costs, less interest
income of $1.4 million. Interest expense for the three months ended March 31,
1997 and the prior period was $8.4 million and $24.2 million, respectively, and
was allocated to the Predecessor Company by applying Lockheed Martin's weighted
average consolidated interest rate to the portion of the Predecessor Company's
invested equity account deemed to be financed by Lockheed Martin's consolidated
debt. The increase in interest expense reflects the Company's higher interest
rates on its third party debt, as compared to the interest rate utilized to
calculate interest expense by the Predecessor Company.

     The income tax provision for the nine months ended December 31, 1997
reflects the Company's effective income tax rate of 46.5%, which was
significantly impacted by the noncash compensation charge of $4.4 million which
is not deductible for income tax purposes. For the three months ended March 31,
1997 and in the prior period, income taxes were allocated to the Predecessor
Company by


                                       40
<PAGE>

Lockheed Martin and the effective income tax rate was significantly impacted by
amortization of costs in excess of net assets acquired, which were not
deductible for income tax purposes. See Note 11 to Consolidated (Combined)
Financial Statements as of December 31, 1997.


SUPPLEMENTAL ANALYSIS OF ANNUAL RESULTS OF OPERATIONS OF THE COMPANY AND THE
   PREDECESSOR COMPANY

     As noted above, the Company's financial statements reflect operations
since the effective date of the L-3 Acquisition, April 1, 1997, and the results
of operations for the year ended December 31, 1996 represent the results of
operations of the Predecessor Company, and include the results of operations of
the Loral Acquired Businesses beginning on April 1, 1996, the effective date of
that acquisition. Accordingly, changes between periods for the year ended
December 31, 1997 to the year ended December 31, 1996 of the Predecessor
Company are significantly affected by the timing of these acquisitions. To
enable investors to better assess the trends in the results of operations and
to facilitate comparisons, the following presentation of results of operations
for the year ended December 31, 1997 were obtained by aggregating, without
adjustment, the historical results of operations of the Predecessor Company for
the period from January 1, 1997 through March 31, 1997 with the historical
results of operations of the Company for the nine months period from April 1,
1997 through December 31, 1997 (together the "1997 period"), and the results of
operations for the year ended December 31, 1996 were obtained by aggregating,
without adjustments, the historical results of operations of the Predecessor
Company for the year ended December 31, 1996 with the historical results of
operations of the Loral Acquired Businesses for the period from January 1, 1996
through March 31, 1996 (together the "1996 period"). All the historical results
were derived from the audited financial statements for respective periods
included herein.

     The following table sets forth historical selected statement of operations
data for the Company, Predecessor Company and the Loral Acquired Businesses for
the periods indicated and the related calendar year results of operation data
derived therefrom.

</TABLE>

     Sales for the 1997 period increased to $705.4 million from $675.3 million
for the 1996 period. Operating income increased to $59.4 million in the 1997
period from $51.5 million in the 1996 period. Operating income is not directly
comparable between the periods as a result of the effects of valuation of
assets and liabilities in accordance with Accounting Principles Opinion No. 16.
 

     The sales increase in the 1997 period was primarily attributable to sales
of the Loral Acquired
Businesses which increased by $18.1 million to $531.4 million in the 1997
period as compared to $513.3 million in the 1996 period. This sales increase
was primarily attributable to increased sales volume on E2-C antenna program,
the E2-C and F-14 display systems and passive microwave components, additional
production and shipments on CHBDL and UAV programs, and partially offset by
lower sales volume on the U-2 Program. Additionally, sales of Communication
Systems -- East increased by $12.0 million to $174.0 million in the current
period from $162.0 million in the 1996 period, and were primarily attributable
to increased sales of power supplies, the GEMnet product line and the P3-C
Repair Depot.

     Operating income increased by $7.9 million or 15.3% to $59.4 million in
the 1997 period from $51.5 million in the 1996 period. Operating margin
increased to 8.4% in the 1997 period as compared


                                       41
<PAGE>

to 7.6% in the 1996 period. The increase in operating income was largely
attributable to cost reductions, increased sales volume of the Loral Acquired
Businesses and operating improvements at Communications Systems -- East.
Operating income for the 1997 period also included (i) a nonrecurring, noncash
compensation charge of $4.4 million recorded effective April 1, 1997, related
to the initial capitalization of L-3 and (ii) fourth quarter cost of sales of
$3.3 million related to on-going certification efforts for the Company's EDS
contract. Excluding the noncash compensation charge and the EDS costs,
operating income would have been $67.1 million for the 1997 period and
operating margin would have been 9.5%.

     EBITDA for the 1997 period increased by $9.2 million to $93.8 million from
$84.6 million for the 1996 period. EBITDA margin increased to 13.3% for the
1997 period from 12.5% for the 1996 period. The increases in EBITDA and EBITDA
margin were attributable to the items affecting the trends in operating income
between the 1997 period and 1996 period discussed above.

</TABLE>

     The results of operations of the Loral Acquired Businesses are reflected
in the results of operations of the Predecessor Company beginning on April 1,
1996, the effective date of that acquisition by Lockheed Martin. During 1996,
sales increased to $543.1 million from $166.8 million in 1995. Operating income
increased to $43.7 million compared with $4.7 million in 1995. Net income
increased to $11.7 million as compared to a net loss of $1.0 million in 1995.
The Loral Acquired Businesses contributed $13.6 million to net income for the
year ended December 31, 1996.

     The sales increase in 1996 was attributable to the sales of the Loral
Acquired Businesses which contributed $381.1 million of the increase. Sales of
Communication Systems -- East decreased in 1996 by $4.8 million as compared to
1995 primarily due to lower volume on Aegis power supplies and SIGINT system
production, partially offset by Local Management Device/Key Processor
("LMD/KP") production startup.

     The increase in 1996 operating income was largely attributable to the
Loral Acquired Businesses, which contributed $36.9 million of the increase.
Communication Systems -- East operating income in 1996 increased $2.2 million
primarily due to improved operating performance on the Shipboard Telephone
Communications ("STC-2") program partially offset by increased costs on the
Space Station contract. Operating margin increased to 8.0% from 2.8%. This
increase is attributable to the improvement in Communication Systems -- East
noted above, higher contract margins and operating improvements in the Loral
Acquired Businesses.

     Allocated interest expense increased to $24.2 million in 1996 from $4.5
million in 1995 due primarily to the acquisition of the Loral Acquired
Businesses, which was assumed to be fully financed by debt, coupled with a
higher debt-to-equity ratio used in the allocation for Communication Systems --
East. See Note 9 to Consolidated (Combined) Financial Statements.

     The effective income tax rate declined to 40% in 1996 as compared to 681%
in 1995. The 1995 effective rate was significantly impacted by non-deductible
amortization of costs in excess of net assets acquired. As a percentage of
income subject to tax, such amortization declined significantly in 1996.

LIQUIDITY AND CAPITAL RESOURCES

     During the third quarter of 1998, the Senior Credit Facilities were
amended to add the Revolving 364 Day Credit Facility (as defined later in this
prospectus) of $185.0 million to the existing Revolving Credit Facility (as
defined later in this prospectus) of $200.0 million. The Revolving 364 Day
Credit Facility expires 364 days after the closing of the amendment, at which
time the Company may (i) request that the creditors extend it for one
additional 364-day period or (ii) exercise an option to convert any or all of
the borrowings outstanding thereunder into term loans which amortize over a
two-year period beginning March 31, 2001, and must be paid in full no later
than March 31, 2003.

     The Revolving 364 Day Credit Facility together with the Company's
Revolving Credit Facility, increased borrowings available to the Company,
before reductions for outstanding letters of credit, to $385.0 million. At
September 30, 1998, available borrowings under the Revolving Credit Facility
and Revolving 364 Day Credit Facility were $28.3 million and $175.0 million,
respectively, after reductions for outstanding borrowings of $145.0 and $10.0
million, respectively, and outstanding letters of credit drawn against the
Revolving Credit Facility of approximately $26.7 million. After giving effect
to the Old Notes Offering, available borrowings under the Senior Credit
Facilities at September 30, 1998 on a pro forma basis would have been $385.0
million, before reductions for outstanding letters of credit.

   
     The Senior Credit Facilities, the Notes, the May 1998 Notes and the 1997
Notes contain financial covenants, which remain in effect so long as any amount
is owed or any commitment to lend exists thereunder by L-3 Communications. The
financial covenants under the Senior Credit Facilities require that (i) L-3
Communications' debt ratio, as defined therein, be less than or equal to 5.00
for the quarter ended September 30, 1998, and that the maximum allowable debt
ratio thereafter decline over time to less than or equal to 3.25 for the
quarters ending September 30, 2002 and thereafter and (ii) L-3 Communications'
interest coverage ratio, as defined therein, be at least 2.00 for the quarter
ended September 30, 1998 and that the interest coverage ratio thereafter
increase over time to at least 3.00 for any fiscal quarters ending September
30, 2002 and thereafter. As of September 30, 1998, L-3 Communications had been
in compliance with these covenants at all times.
    

     The Company has a substantial amount of indebtedness. Based upon the
current level of operations, management believes that the Company's cash flow
from operations, together with available borrowings under the Senior Credit
Facilities, will be adequate to meet its anticipated requirements for working
capital, capital expenditures, research and development expenditures, program
and other discretionary investments, interest payments and scheduled principal
payments for the foreseeable future including at least the next three years.
There can be no assurance, however, that the Company's business will continue
to generate cash flow at or above current levels or that currently anticipated
improvements will be achieved. If the Company is unable to generate sufficient
cash flow from operations in the future to service its debt, it may be required
to sell assets, reduce capital expenditures, refinance all or a portion of its
existing debt or obtain additional financing. The Company's ability to make
scheduled principal payments, to pay interest on or to refinance its
indebtedness depends on its future performance and financial results, which, to
a certain extent, are subject to general conditions in or affecting the defense
industry and to general economic, political, financial, competitive,
legislative and regulatory factors beyond its control. There can be no
assurance that sufficient funds will be available to enable the Company to
service its indebtedness, including the Notes, the 1997 Notes and the May 1998
Notes, or make necessary capital expenditures and program and discretionary
investments.

     The Company has reached agreement or is in discussions regarding a number
of potential acquisition opportunities and expects to use the Senior Credit
Facilities to fund these transactions if the Company proceeds with them. If all
of these potential acquisitions were consummated, they would require the
Company to use all or substantially all of its currently available borrowing
capacity, and perhaps seek additional borrowing capacity, in 1999. See "Risk
Factors--Our Acquisition Strategy Involves Certain Risks" and "--We Have
Discretion Over the use of Funds Raised in the Old Notes Offering".


                                       43
<PAGE>

     The indebtedness under the Senior Credit Facilities is guaranteed by
Holdings and by many of the Company's subsidiaries. The payment of principal
and premium, if any, and interest on the 1997 Notes and May 1998 Notes and
principal and premium or liquidated damages, if any, and interest on the Notes
is unconditionally guaranteed, on an unsecured senior subordinated basis,
jointly and severally, by many of the Company's subsidiaries, all of which are
wholly-owned subsidiaries.

     To mitigate risks associated with changing interest rates on certain of
its debt, the Company entered into interest rate cap and floor contracts (the
"interest rate agreements"). The Company manages exposure to counterparty
credit risk by entering into the interest rate agreements only with major
financial institutions that are expected to perform fully under the terms of
such agreements. Cash payments to (from) the Company and the counterparties are
made at the end of the quarter to the extent due under the terms of the
interest rate agreements. Such payments are recorded as adjustments to interest
expense. The initial costs of the interest rate agreements are capitalized as
deferred debt issuance costs and amortized into interest expense. The impact of
the interest rate agreements on interest expense was not material for the nine
months ended September 30, 1998 or for the nine months ended December 31, 1997.
See Note 10 to the Consolidated (Combined) Financial Statements.


BALANCE SHEET

     The increases from December 31, 1997 to September 30, 1998 in contracts in
process, other current assets, property, plant and equipment, net of
accumulated depreciation and amortization, intangibles, customer advances,
other current liabilities, and pension and post-retirement benefits of $178.6
million, $13.7 million, $34.2 million, $310.9 million, $24.1 million, $21.1
million, and $56.3 million, respectively, are principally related to the
acquired businesses. The increase in other assets of $9.1 million is primarily
attributable to debt issuance costs incurred in connection with the May 1998
Notes and amendments to the Senior Credit Facilities which have been deferred
and are being amortized over the terms of underlying debt.

     Working capital increased by $9.2 million to $141.0 million at September
30, 1998 from $131.8 million at December 31, 1997. Working capital, adjusted to
exclude cash and the current portion of long term debt, increased by $76.0
million from December 31, 1997 to September 30, 1998 and was primarily
attributable to the working capital of the acquired businesses. The Company's
current ratio at September 30, 1998 decreased to 1.6:1 compared with 2.0:1 at
December 31, 1997. The Company's current ratio at December 31, 1997 remained
constant at 2.0:1 as compared to the Predecessor Company's current ratio at
December 31, 1996.

</TABLE>

     NET CASH FROM (USED IN) OPERATING ACTIVITIES: Cash from operating
activities of the Company for the nine months ended September 30, 1998 was
$48.2 million. Earnings after adjustment for non-cash items and deferred income
taxes provided $58.8 million and uses of cash for net changes in operating
assets and liabilities, net of amounts acquired was $10.6 million.

<PAGE>

     Net cash from operating activities for the nine months ended September 30,
1997 was $40.1 million. Earnings after adjustment for noncash items and
deferred income taxes provided $35.3 million. Changes in operating assets and
liabilities, consisting primarily of increases in accrued employment costs and
accrued interest and decreases in accounts payable and other current
liabilities, all attributable to timings of payments contributed $4.8 million.

     NET CASH (USED IN) INVESTING ACTIVITIES: Cash used in investing activities
for the nine months ended September 30, 1998 was $417.8 million and consisted
primarily of $412.5 million, net of cash acquired, paid by the Company for
acquisitions of businesses. The Company typically makes capital expenditures
related primarily to improvement of manufacturing facilities and equipment. The
Company expects that its capital expenditures for 1998 will be approximately
$27.0 million.

     Cash used in investing activities for the nine months ended September 30,
1997 was $483.3 million and consisted primarily of $470.7 million paid by the
Company for the L-3 Acquisition.

     NET CASH FROM FINANCING ACTIVITIES: For the nine months ended September
30, 1998, the Company's cash from financing activities was $297.9 million.

     On May 19, 1998, Holdings sold 6.9 million shares of its common stock in
the IPO representing 25.2% of Holdings' common stock. The net proceeds from the
IPO amounted to $139.5 million after underwriting discounts and commissions and
expenses of $12.3 million and were contributed by Holdings to the Company.
Concurrent with the Holdings IPO, the Company sold $180.0 million in aggregate
principal amount of the May 1998 Notes, whose net proceeds amounted to $173.8
million after debt issuance costs of $6.2 million. The combined net proceeds
from the contribution of the Holdings IPO and the May 1998 Notes of $313.3
million were used to (i) prepay all $171.0 million of borrowings outstanding
under the Term Loan Facilities (as defined), (ii) repay $67.8 million of then
outstanding borrowings under the Revolving Credit Facility which were primarily
made to finance the Ocean Systems acquisition and (iii) partially finance the
SPD acquisition. During the third quarter of 1998, the Company also made
borrowings, net of repayments, under the Senior Credit Facilities of $155.0
million primarily to partially finance the SPD acquisition.

     Cash from financing activities of the Company was $483.0 million for the
nine months ended September 30, 1997, and was primarily due to the debt
incurred and proceeds from the issuance of common stock related to the initial
capitalization of the Company and the financing of the L-3 Acquisition. Cash
from financing activities also included $20.6 million of advances from Lockheed
Martin to the Predecessor Company. Prior to the L-3 Acquisition, the
Predecessor Company participated in the Lockheed Martin cash management system,
under which all cash was received and all payments were made by Lockheed
Martin. For purposes of the statement of cash flows, all transactions with
Lockheed Martin were deemed to have been settled in cash at the time they were
recorded by the Predecessor Company.

</TABLE>

     NET CASH FROM (USED IN) OPERATING ACTIVITIES: Cash provided by operating
activities for the year ended December 31, 1997 was $57.6 million. Earnings
after adjustment for non-cash items and deferred income taxes provided $57.9
million, and uses of cash for net changes in operating assets and liabilities
was $0.3 million.


                                       45
<PAGE>

     Cash provided by operating activities of the Predecessor Company was $30.7
million in 1996 and $9.3 million in 1995. The increase of $21.4 million in 1996
was due primarily to the impact of the Loral Acquired Businesses which were
acquired by Lockheed Martin effective April 1, 1996. Earnings after adjustment
for non-cash items provided $36.7 million, offset by changes in other operating
assets and liabilities. Without the Loral Acquired Businesses, cash provided by
operating activities for Communication Systems--East increased to $13.7 million
in 1996, 46% over 1995.

     NET CASH (USED IN) INVESTING ACTIVITIES:  Cash used in investing
activities for the year ended December 31, 1997 was $462.1 million and
consisted primarily of $466.3 million paid by the Company for the L-3
Acquisition and capital expenditures of $16.2 million, partially offset by
proceeds from the sale of the Company's Sarasota, Florida property of
approximately $9.5 million and cash received from Lockheed Martin of $12.2
million in connection with the Company's assumption of obligations under the
contract for the U.S. Army's Command and Control Vehicle ("C2V") Mission Module
Systems ("MMS").

     During the year ended December 31, 1996, $287.8 million was paid by the
Predecessor Company for the acquisition of the Loral Acquired Businesses. See
Note 4 to the Consolidated (Combined) Financial Statements.

     All transactions between the Businesses and Lockheed Martin have been
accounted as settled in cash at the time such transactions were recorded by the
Businesses. Accordingly, in 1996, cash flows reflect the purchase of the Loral
Acquired Businesses.

     NET CASH FROM (USED IN) FINANCING ACTIVITIES: Cash from financing
activities was $482.0 million for the year ended December 31, 1997, and was
primarily from the debt incurred and proceeds from the issuance of common stock
which were issued to finance the L-3 Acquisition.

     The Company was initially capitalized and the related L-3 Acquisition was
funded by a combination of equity of $125.0 million and debt of $400.0 million
aggregating $525.0 million. The $125.0 million of equity was contributed by
Holdings to the Company. The Holdings equity of $125.0 million was comprised of
$80.0 million in cash contributed to Holdings by the Lehman Partnership and
Senior Management and a $45.0 million retained interest in Holdings by Lockheed
Martin representing partial consideration to Lockheed Martin for its sale of
the Predecessor Company to the Company. In connection with the L-3 Acquisition,
the Company entered into a $275.0 million credit facility consisting of $175.0
million of term loans (the "Term Loan Facilities") and a $100.0 million
revolving credit facility (initially, and as amended, the "Revolving Credit
Facility"). The initial debt balance of $400.0 million consisted of $175.0
million of borrowings under the Term Loan Facilities and the sale of $225.0
million of 103/8% Senior Subordinated Notes (the "1997 Notes") due May 1, 2007.
 

     Prior to the L-3 Acquisition, the Predecessor Company participated in the
Lockheed Martin cash management system, under which all cash was received and
all payments were made by Lockheed Martin. For purposes of the statements of
cash flows, all transactions with Lockheed Martin were deemed to have been
settled in cash at the time they were recorded by the Predecessor Company. Net
cash from (used in) financing activities of the Predecessor Company for the
three months ended March 31, 1997 and the years ended December 31, 1996 and
1995, were approximately $20.6 million, $267.3 million and ($3.8) million,
respectively, and represent advances from (repayments to) Lockheed Martin, the
Predecessor Company's parent company.


BACKLOG

     The Company's funded backlog September 30, 1998 was $813.8 million,
compared with $516.9 million at December 31, 1997 and the Predecessor Company's
funded backlog at December 31, 1996 of $542.5 million. Funded orders, on a pro
forma basis, for the Company for 1997 were $711.5 million. The Predecessor
Company's funded orders for 1996 were $619.5 million. It is expected that
approximately 72% of the backlog at September 30, 1998 will be recorded as
sales over the next twelve-month period. However, there can be no assurance
that the Company's backlog will become revenues in any particular period, if at
all. See "Risk Factors -- Our Backlog of Orders Could be Terminated".
Approximately 70% of the total backlog at September 30, 1998 was directly or
indirectly for defense contracts for end use by the Government. Approximately
$687.7 million of total backlog


                                       46
<PAGE>

at September 30, 1998 was directly or indirectly for U.S. and foreign
government defense contracts, and approximately $15.0 million of total backlog
was directly or indirectly for U.S. and foreign government non-defense
contracts. Foreign customers accounted for approximately $176.3 million of the
total backlog.


RESEARCH AND DEVELOPMENT

     Research and development, including bid and proposal costs ("R&D costs"),
sponsored by the Company on a pro forma basis for the nine-month period ended
September 30, 1998 was $43.5 million. Pro forma R&D costs sponsored by the
Company were $53.0 million for the year ended December 31, 1997, and $53.7
million for the year ended December 31, 1996. R&D costs sponsored by the
Predecessor Company were $12.0 million, $36.5 million and $9.8 million for the
three months ended March 31, 1997 and the years ended December 31, 1996 and
1995, respectively. The Loral Acquired Businesses sponsored R&D costs of $5.6
million for the three months ended March 31, 1996 and $21.4 million for the
year ended December 31, 1995. Accordingly, the Company, Predecessor Company and
the Loral Acquired Businesses, in the aggregate, sponsored R&D costs of $40.9
million, $42.1 million and $31.2 million, respectively, for the years ended
December 31, 1997, 1996 and 1995. Customer-funded research and development was
$117.1 million in 1997, as compared with $153.5 million for 1996. The decrease
in customer-funded research and development in 1997 is due primarily to
research and development programs existing in 1996 which moved into the
production phase during 1997.


CONTINGENCIES

     See Note 9 to the Unaudited Condensed Consolidated (Combined) Financial
Statements as of September 30, 1998 and Note 13 to the Consolidated (Combined)
Financial Statements as of December 31, 1997.


RECENT ACCOUNTING PRONOUNCEMENTS

     In September 1997, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 131,
"Disclosure about Segments of an Enterprise and Related Information". SFAS No.
131 establishes accounting standards for the way that public enterprises report
information about operating segments and requires that those enterprises report
selected information about operating segments in interim financial reports
issued to shareholders. In February 1998, the FASB issued SFAS No. 132,
"Employers' Disclosures about Pensions and Other Postretirement Benefits". SFAS
No. 132 revises employers' disclosures about pension and other postretirement
benefits plans. It does not change the measurement or recognition of those
plans. It standardizes the disclosure requirements for pensions and other
postretirements benefits to the extent practicable, requires additional
information on changes in the benefit obligations and fair values of plan
assets that will facilitate financial analysis, and eliminates certain
disclosures that are no longer as useful as they were when SFAS No. 87
"Employers' Accounting for Pensions", SFAS No. 88 "Employers' Accounting for
Settlements and Curtailments of Defined Benefit Plans and for Termination
Benefits" and SFAS No. 106 "Employers Accounting for Postretirement Benefits
Other Than Pensions" were issued. SFAS 132 suggests combined formats for
presentation of pension and other postretirement benefits disclosures. The
Company is currently evaluating the impact, if any, of SFAS No. 131 and SFAS
No. 132.

     In April 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
98-5, "Reporting on the Costs of Start-Up Activities" ("SOP 98-5"), which
provides guidance on the financial reporting of start-up and organization
costs. It requires costs of start-up activities and organization costs to be
expensed as incurred. SOP 98-5 is effective for fiscal years beginning after
December 15, 1998. The Company is currently evaluating the impact, if any, of
SOP 98-5.

     In September 1998, the FASB issued SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS No. 133 establishes
accounting and reporting standards for derivative


                                       47
<PAGE>

instruments, including certain derivative instruments embedded in other
contracts and for hedging activities. It requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The Company is currently
evaluating the impact, if any, of SFAS No. 133 which is effective for all
quarters of fiscal years beginning after September 15, 1999.


INFLATION

     The effect of inflation on the Company's sales and earnings has not been
significant. Although a majority of the Company's sales are made under
long-term contracts, the selling prices of such contracts, established for
deliveries in the future, generally reflect estimated costs to be incurred in
these future periods. In addition, some contracts provide for price adjustments
through escalation clauses.


YEAR 2000 COMPLIANCE

     The inability of business processes to continue to function correctly
after the beginning of the Year 2000 could have serious adverse effects on
companies and entities throughout the world. Because the Company's business
units operate autonomously, each business unit has undertaken an effort to
identify and mitigate Year 2000 issues in their information systems, products,
facilities, suppliers and customers. The Company's Year 2000 compliance efforts
are a composite of its business units' individual Year 2000 compliance efforts,
coordinated through a company-wide program instituted to oversee, guide and
track its business units' Year 2000 compliance efforts and to facilitate
company-wide communications regarding Year 2000 compliance methods.

     Each business unit has appointed a Year 2000 project manager who oversees
a team responsible for performing its Year 2000 efforts in four phases: (i)
define, identify and inventory possible sources of Year 2000 issues, including
internal systems and products and services sold to customers; (ii) analyze and
determine the nature and extent of Year 2000 issues and develop project plans
to address those issues; (iii) implement and execute project plans to remediate
or replace non-compliant items, as appropriate, based upon assessed risk and
priority; and (iv) commence and complete testing, continue monitoring readiness
and prepare necessary contingency plans. The progress of this program is
monitored at each business unit with oversight by Corporate Management. This
oversight includes periodic reviews as well as visits to each business unit to
monitor progress with the plans. Management plans to complete the first three
phases of the program for a substantial majority of critical systems within the
Company by the end of March 1999 and to have nearly all significant information
systems, products and facilities in the final phase of the program by mid-1999.
 

     The total costs associated with the Company's Year 2000 efforts are
estimated to be $16.2 million, including $7.1 million of capitalizable costs
with the remaining costs expensed as incurred. The Company has incurred
approximately $6.6 million of such costs to date. Substantially all of the
remaining estimated costs are expected to be incurred in 1999.

     The Company believes that the decentralized nature of its systems and its
Year 2000 efforts reduce the risk that its operations will be interrupted by
the failure of any individual internal critical system to be Year 2000
compliant by the end of 1999. The Company's business operations are also
dependent on the Year 2000 readiness of its customers and infrastructure
suppliers in areas such as utilities, communications, transportation and other
services. In those environments, there could be instances of failure that could
cause disruptions in business transaction processes of the Company. The
likelihood and effects of failures in infrastructure systems and in the
customer and supply chains cannot be estimated, but such a failure could
potentially result in a material adverse impact on results of operations,
liquidity or financial position of the Company. The Company continues to
attempt to assess the Year 2000 compliance and readiness of its material
third-party suppliers and customers. Such attempts include written inquiries as
to their Year 2000 certification of compliance. As indicated above, contingency
plans for suppliers, customers and critical systems impacted by Year 2000
issues will be developed in the fourth quarter. These estimates and projections
could change as work progresses.

COMPANY OVERVIEW

     L-3 Communications is a leading merchant supplier of sophisticated secure
communication systems and specialized communication products. We produce
secure, high data rate communication systems, microwave components, avionics
and ocean systems and telemetry, instrumentation and space products. These
systems and products are critical elements of virtually all major
communication, command and control, intelligence gathering and space systems.
Our systems and specialized products are used to connect a variety of airborne,
space, ground- and sea-based communication systems and are used in the
transmission, processing, recording, monitoring and dissemination functions of
these communication systems. Our customers include the U.S. department of
defense, certain U.S. government intelligence agencies, major aerospace and
defense contractors, foreign governments and commercial customers. For the
twelve-month period ended September 30, 1998, we had pro forma sales of
$1,139.7 million and pro forma EBITDA of $148.4 million. Our funded backlog as
of September 30, 1998 was $813.8 million. These results reflect internal growth
and the execution of our strategy of acquiring businesses that complement or
extend our product lines.

     Our business areas employ proprietary technologies and capabilities and
have leading positions in their respective primary markets. We have organized
our operations into two primary business areas: Secure Communication Systems
and Specialized Communication Products. For the twelve-month period ended
September 30, 1998, the Secure Communication Systems business area generated
approximately $481.5 million of pro forma sales and $61.2 million of pro forma
EBITDA, and the Specialized Communication Products business area generated
$658.2 million of pro forma sales and $87.2 million of pro forma EBITDA. In
addition, we are seeking to expand our products and technologies in commercial
markets as we discuss under "--Emerging Commercial Products" below.

     SECURE COMMUNICATION SYSTEMS. We are the established leader in secure,
high data rate communications for military and other U.S. government
reconnaissance and surveillance applications. Our Secure Communication Systems
operations are located in Salt Lake City, Utah, Camden, New Jersey and
Shrewsbury, New Jersey. These operations are predominantly cost plus, sole
source contractors supporting long-term programs for the U.S. armed forces and
classified customers. Our major secure communication programs and systems
include:

    o  secure data links for airborne, satellite, ground- and sea-based remote
       platforms for information collection, command and control and
       dissemination to users in real time;

    o  strategic and tactical signal intelligence systems that detect, collect,
       identify, analyze and disseminate information and related support
       contracts for military and intelligence efforts;

    o  secure telephone, fax and network equipment and encryption management;
 

    o  communication software support services to military and related
       government intelligence markets; and

    o  communications systems for surface and undersea platforms and manned
       space flights.

     We believe that we have developed virtually every high bandwidth data link
that is currently used by the military for surveillance and reconnaissance. We
are also a leading supplier of communication software support services to
military and related government intelligence markets. In addition to these core
government programs, we are capitalizing on our technology base by expanding
into related commercial communication equipment markets. For instance, we are
applying our high data rate communications and archiving technology to the
medical image archiving market and our wireless communication expertise to
develop local wireless loop telecommunications equipment for the last mile
interconnect.

     SPECIALIZED COMMUNICATION PRODUCTS. This business area encompasses three
product categories:

     Microwave Components. We are the preeminent worldwide supplier of
commercial off-the-shelf, high-performance microwave components and frequency
monitoring equipment. Our microwave products are sold under the
industry-recognized Narda brand name through a standard catalog to wireless,
industrial and military communication markets. We also provide
state-of-the-art, space-qualified communication components including channel
amplifiers and frequency filters for the commercial communications satellite
market serving all frequencies, including Ka band. Approximately 79% of
Microwave Components sales for the nine-month period ended September 30, 1998
were made to commercial customers, including Loral Space & Communications,
Ltd., Motorola, Inc., Lucent Technologies Inc., AT&T Corp. and Lockheed Martin.
 

     Avionics and Ocean Products. Avionics and Ocean Products include our
aviation recorders, display systems, antenna systems, acoustic undersea warfare
systems and naval power distribution, conditioning, switching and protection
equipment for naval ships and submarines. We are the world's leading
manufacturer of commercial cockpit voice and flight data recorders (known as
"black boxes"). These recorders are sold under the Fairchild brand name both to
aircraft manufacturers and to the world's major airlines for their existing
fleets of aircraft. Our aviation recorders are also installed on military
transport aircraft throughout the world. We provide military and high-end
commercial displays for use in military aircraft. We also manufacture high
performance surveillance and precision millimeter wave antennas and related
equipment for U.S. Air Force, U.S. Army and U.S. Navy aircraft and are the
leading supplier of ground-based radomes. We are one of the world's leading
product suppliers of acoustic undersea warfare systems and airborne dipping
sonar systems to the U.S. and over 20 foreign navies. We are the only fully
integrated, full-line provider of qualified turnkey electrical power delivery
and management systems for U.S. Navy surface ships and submarines.

     Telemetry, Instrumentation and Space Products. Our Telemetry,
Instrumentation and Space Products operations develop and manufacture
commercial off-the-shelf, real-time data collection and transmission products
and components for missile, aircraft and space-based electronic systems. These
products are used to gather flight data and other critical information and
transmit it from air or space to the ground. Telemetry products are also used
for range safety and training applications to simulate battlefield situations.
We are also a leading global satellite communications systems provider offering
systems and services used in the satellite transmission of voice, video and
data through earth stations for uplink and downlink terminals. We provide
global satellite communications systems and services to customers that include
foreign post, telephone and telegraph administrations, domestic and
international prime communications infrastructure contractors,
telecommunications and satellite service providers, broadcasters and
media-related companies, government agencies and large corporations. We also
provide commercial, off-the-shelf satellite control software, TT&C, mission
processors and software engineering services to the worldwide military,
civilian and commercial satellite markets.

     EMERGING COMMERCIAL PRODUCTS. Building upon our core technical expertise
and capabilities, we are seeking to expand into several closely aligned
commercial business areas and applications. Emerging Commercial Products
currently include the following four niche markets:

    o  medical archiving and simulation systems;

    o  local wireless loop telecommunications equipment;

    o  airport security equipment; and

    o  information network security.

     A majority of these commercial products were developed based on technology
used in our military businesses with relatively small additional expense. We
are applying our technical capabilities in high data rate communications and
archiving technology developed in our Secure Communication Systems business
area to the medical image archiving market together with the General Electric
Company's medical systems business. Based on secure, high data rate
communication technology also


                                       50
<PAGE>

developed in our Secure Communication Systems business area, we have developed
local wireless loop telecommunications equipment that is primarily designed for
emerging market countries and rural areas where voice and data communication
infrastructure is inadequate or does not exist. We have completed the
development phase for the local wireless loop telecommunications equipment and
have begun deliveries. In addition, the Federal Aviation Administration (the
"FAA") awarded us a development contract for next generation airport security
equipment for explosive detection. On November 23, 1998, we received FAA
certification for our eXaminer 3DX (Trade Mark)  6000 system which is the only
second generation system to receive certification and the only system to
generate full, three-dimensional images of all objects in a piece of baggage.
To capitalize on commercial opportunities for the information security
technologies we developed in our Secure Communications Systems business area,
we have also created a new subsidiary focusing on developing and marketing
secure information and communication systems for commercial clients. This
subsidiary acquired a network security software product through a
majority-owned joint venture. We released the third generation of this network
security software, ExpertTM 3.0, on November 9, 1998. Taken together, revenues
generated from our Emerging Commercial Products have not yet been material to
us.

INDUSTRY OVERVIEW


     The defense industry has undergone significant changes precipitated by
ongoing federal budget pressures and new roles and missions to reflect changing
strategic and tactical threats. Since the mid-1980's, the overall U.S. defense
budget has declined in real dollars. In response, the DoD had focused its
resources on enhancing its military readiness, joint operations and digital
command and control communications capabilities by incorporating advanced
electronics to improve the performance, reduce operating cost and extend the
life expectancy of its existing and future platforms. The emphasis on system
interoperability, force multipliers and providing battlefield commanders with
real-time data is increasing the electronics content of nearly all of the major
military procurement and research programs. As a result, the DoD's budget for
communications and defense electronics is expected to grow.


     The industry has also undergone dramatic consolidation resulting in the
emergence of three dominant prime system contractors (The Boeing Company
("Boeing"), Lockheed Martin and Raytheon Company ("Raytheon")). One outgrowth
of this consolidation among the remaining major prime contractors is their
desire to limit purchases of products and sub-systems from one another.
However, there are numerous essential products, components and systems that are
not economical for the major prime contractors to design, develop or
manufacture for their own internal use which creates opportunities for merchant
suppliers such as L-3. As the prime contractors continue to evaluate their core
competencies and competitive position, focusing their resources on larger
programs and platforms, the Company expects the prime contractors to continue
to exit non-strategic business areas and procure these needed elements on more
favorable terms from independent, commercially oriented merchant suppliers.
Recent examples of this trend include divestitures of certain non-core
defense-related businesses by AlliedSignal Inc. ("AlliedSignal"), Lockheed
Martin and Raytheon.


     The prime contractors' focus on cost control is also driving increased use
of commercial off-the-shelf products for upgrades of existing systems and in
new systems. The Company believes the prime contractors will continue to be
under pressure to reduce their costs and will increasingly seek to focus their
resources and capabilities on major systems, turning to commercially oriented
merchant suppliers to produce sub-systems, components and products. Going
forward, successful merchant suppliers will use their resources to complement
and support, rather than compete with the prime contractors. L-3 anticipates
the relationship between the major prime contractors and their primary
suppliers will, as in the automotive and commercial aircraft industry, develop
into critical partnerships encompassing increasingly greater outsourcing of
non-core products and systems by the prime contractors to their key merchant
suppliers and increasing supplier participation in the development of future
programs. Early involvement in the upgrading of existing systems and the design
and engineering of new systems incorporating these outsourced products will
provide merchant suppliers, including the Company, with a competitive advantage
in securing new business and provide the prime contractors with significant
cost reduction opportunities through coordination of the design, development
and manufacturing processes.


BUSINESS STRATEGY


     Management has successfully integrated the business units of Lockheed
Martin it acquired in the L-3 Acquisition and enhanced the Company's operating
efficiency through reduced overhead expenses and facility rationalization.
These efforts resulted in improvements in sales, profitability and competitive
contract award win rates. Going forward, L-3 intends to leverage its market
position, diverse program base and favorable mix of cost plus to fixed price
contracts to enhance its profitability and to establish itself as the premier
merchant supplier of communication systems and products to the major prime
contractors in the aerospace/defense industry as well as the Government. The
Company's strategy to continue to achieve its objectives includes:


                                       55
<PAGE>

      o  EXPAND MERCHANT SUPPLIER RELATIONSHIPS. Management has developed
   strong relationships with virtually all of the prime contractors, the DoD
   and other major government agencies, enabling L-3 to identify business
   opportunities and anticipate customer needs. As an independent merchant
   supplier, the Company anticipates its growth will be driven by expanding
   its share of existing programs and by participating in new programs.
   Management identifies opportunities where it believes it will be able to
   use its strong relationships to increase its business presence and allow
   its customers to reduce their costs. The Company also expects to benefit
   from increased outsourcing by prime contractors who in the past may have
   limited their purchases to captive suppliers and who are now expected to
   view L-3's capabilities on a more favorable basis given its status as an
   independent company. L-3's independent status positions it to be the
   desired merchant supplier to multiple bidders on prime contract bids. As an
   example of the Company's merchant supplier strategy, L-3 equipment is
   included in all three prime contractor bids for the Airborne Standoff Radar
   ("ASTOR") program in the United Kingdom and both prime contractor bids for
   the DoD's Joint Air Surface Standoff Missile ("JASSM") program.


      o  SUPPORT CUSTOMER REQUIREMENTS. A significant portion of L-3's sales
   are derived from high-priority, long-term programs and from programs for
   which the Company has been the incumbent supplier, and in many cases acted
   as the sole provider, over many years. Approximately 60% of the Company's
   total pro forma sales of $834.5 million for the nine-month period ended
   September 30, 1998 were generated from sole source contracts. L-3's
   customer satisfaction and excellent performance record are evidenced by its
   performance-based award fees exceeding 89% on average over the past two
   years. Management believes prime contractors will increasingly award
   long-term, sole source, outsourcing contracts to the merchant supplier they
   believe is most capable on the basis of quality, responsiveness, design,
   engineering and program management support as well as cost. Reflecting
   L-3's strong competitive position, the Company has experienced a contract
   award win rate on a pro forma basis for the nine-month period ended
   September 30, 1998 in excess of 59% on new competitive contracts for which
   it competes and in excess of 90% on contracts for which it is the
   incumbent. The Company intends to continue to align its research and
   development, manufacturing and new business efforts to complement its
   customers' requirements and provide state-of-the-art products.


      o  ENHANCE OPERATING MARGINS. Since the L-3 Acquisition in April 1997,
   management has reduced corporate administrative expenses and facilities
   costs, increased sales and improved competitive contract award win rates.
   Enhancement of operating margins was primarily due to efficient management
   and elimination of significant corporate expense allocations which existed
   prior to the L-3 Acquisition. Pro forma EBITDA (excluding the 1998
   Acquisitions) as a percentage of sales improved from 12.5% in 1996 to 13.4%
   in 1997. Management intends to continue to enhance its operating
   performance by reducing overhead expenses, continuing consolidation and
   increasing productivity.


      o  LEVERAGE TECHNICAL AND MARKET LEADERSHIP POSITIONS. L-3 has developed
   strong, proprietary technical capabilities that have enabled it to capture
   a number one or two market position in most of its key business areas,
   including secure, high data rate communications systems, solid state
   aviation recorders, telemetry, instrumentation and space products, advanced
   antenna systems and high performance microwave components. For the period
   from January 1, 1996 to September 30, 1998, the Company, on a pro forma
   basis, has invested over $150.0 million in Company-sponsored independent
   research and development, including bid and proposal costs, in addition to
   making substantial investments in its technical and manufacturing
   resources. Further, the Company has a highly skilled workforce including
   approximately 2,500 engineers. Management is applying the Company's
   technical expertise and capabilities into several closely aligned
   commercial business areas and applications, such as medical imaging archive
   management, wireless telephony and airport security equipment and will
   continue to explore other similar commercial opportunities.


                                       56
<PAGE>

      o  MAINTAIN DIVERSIFIED BUSINESS MIX. The Company enjoys a diverse
   business mix with a limited program exposure, a favorable balance of cost
   plus and fixed price contracts, a significant sole source follow-on
   business and an attractive customer profile. The Company's largest program,
   representing approximately 7% of $834.5 million pro forma sales for the
   nine-month period ended September 30, 1998, is a long-term, sole source,
   cost plus contract for the U-2 Program. No other program represented more
   than 5% of pro forma sales for the nine-month period ended September 30,
   1998. Further, the Company's pro forma sales mix of contracts for the
   nine-month period ended September 30, 1998 was 29% cost plus and 71% fixed
   price, providing the Company with a favorable mix of predictable
   profitability (cost plus) and higher margin (fixed price) business. L-3
   also enjoys an attractive customer mix of defense and commercial business,
   with DoD related sales accounting for 68% and commercial and federal
   (non-DoD) sales accounting for approximately 32% of pro forma sales of
   $834.5 million for the nine-month period ended September 30, 1998. The
   Company intends to leverage this favorable business profile to expand its
   merchant supplier business base.

      o  CAPITALIZE ON STRATEGIC ACQUISITION OPPORTUNITIES. Recent industry
   consolidation has essentially eliminated traditional middle-tier
   aerospace/defense companies. This level of consolidation is now beginning
   to draw the concern of the DoD and federal anti-trust regulators. In 1997
   and 1998, a number of merchant supplier companies were sold: the Computing
   Devices International division of Ceridian to General Dynamics Corp.
   ("General Dynamics"), Kaman Sciences Corp. ("Kaman Sciences") to ITT
   Industries, Inc. ("ITT"), BDM International, Inc. ("BDM") to TRW Inc.
   ("TRW"), TASC Inc., a subsidiary of Primark Corporation, to Litton
   Industries, Inc. ("Litton") and Tracor, Inc. to GEC Marconi, a unit of The
   General Electric Company, p.l.c. As a result, the Company anticipates that
   the consolidation of the smaller participants in the defense industry will
   create attractive complementary acquisition candidates for L-3 in the
   future as these companies continue to evaluate their core competencies and
   competitive position. L-3 intends to enhance its existing product base
   through internal research and development efforts as well as selective
   acquisitions and add new products to its product base through acquisitions
   in areas synergistic with L-3's present technology. The Company seeks to
   acquire potential targets with the following criteria: (i) significant
   market position in its business area, (ii) product offerings which
   complement and/or extend those of L-3 and (iii) positive future growth and
   earnings prospects.



ACQUISITION STRATEGY

   
     Since L-3's formation in April 1997, the Company has actively pursued its
acquisition strategy. Since completing the L-3 Acquisition, the Company has
purchased twelve additional businesses for an aggregate cash purchase price
including assumed debt and expenses, net of cash acquired, of approximately
$534.0 million, subject to certain post-closing adjustments, and in certain
cases additional consideration based on post-closing performance. The Company
considers and executes strategic acquisitions on an ongoing basis and may be
evaluating acquisitions or engaged in acquisition negotiations at any given
time. The Company has reached agreement on or is in discussions regarding a
number of potential acquisition opportunities and expects to use its bank
credit facilities to fund these transactions if it proceeds with them. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition -- Liquidity and Capital Resources".
    


RECENT DEVELOPMENTS

     SPD Technologies, Inc. On August 13, 1998, the Company acquired all of the
outstanding common stock of SPD for $230.0 million in cash, subject to certain
post-closing adjustments. SPD is the leading supplier to the U.S. Navy for
subsystems that manage, control, distribute, protect and condition electrical
power in surface ships and submarines. SPD's major products include electronic
solid state protection products, switchgear, high-speed transfer switches,
fault isolation units, frequency converters and inverters, voltage transformers
and uninterruptible power supply systems. SPD's


                                       57
<PAGE>

products are installed in every nuclear submarine, aircraft carrier and surface
platform operated by the U.S. Navy. SPD also provides shipboard communications
and control as well as support service for installed products. This acquisition
was financed using cash from operations and borrowings under the Company's bank
credit facilities.

   
     Microdyne Corporation. On December 3, 1998, the Company signed an
agreement to acquire all of the outstanding common stock of Microdyne for
approximately $90.0 million in cash, including the repayment of Microdyne's
debt. For the fiscal year ended September 30, 1998, Microdyne reported actual
revenues of $58.3 million, operating income of $1.3 million and net income of
$0.3 million. On a pro forma basis, including acquisitions Microdyne made
during its 1998 fiscal year as if they had occurred at the beginning of its
fiscal year, Microdyne's revenues would have been $73.5 million, operating
income was $3.6 million and net income was $0.9 million. Microdyne's actual
earnings before interest, taxes, depreciation and amortization for the recent
fiscal year was $2.9 million. Pro forma earnings before interest, taxes,
depreciation and amortization would have been $11.1 million before
non-recurring charges of $5.1 million primarily for the write-off of acquired
in-process research and development costs. Pursuant to the acquisition
agreement, one of the Company's subsidiaries has purchased 91.9% of the common
stock of Microdyne in a cash tender offer. We expect to complete the merger of
Microdyne with this subsidiary in early 1999. Microdyne is a leading global
developer and manufacturer of aerospace telemetry receivers, secure
communications and technical support services, including specialized telemetry
high-frequency radios used in aerospace and satellite communications for data
gathering and analysis. Microdyne also provides products for the government and
commercial signal intelligence markets and support and repair services for
electronic products companies. Microdyne's aerospace telemetry products will
enable us to provide integrated solutions to our space customers' requirements
for command, control, telemetry and tracking. The purchase of shares of
Microdyne common stock was financed using available cash and borrowings under
the Senior Credit Facilities. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition -- Liquidity and Capital
Resources".
    


HISTORY

     Holdings, which owns all of the Company's common stock, was formed in
April 1997 by Mr. Frank C. Lanza, the former President and Chief Operating
Officer of Loral, Mr. Robert V. LaPenta, the former Senior Vice President and
Controller of Loral (collectively, "Senior Management"), the Lehman Partnership
and Lockheed Martin to carry-out the L-3 Acquisition. In May 1998, Holdings
successfully completed the IPO, raising net proceeds of $139.5 million which
Holdings contributed to L-3. The Company raised net proceeds of $173.8 million
in a concurrent debt offering. In December 1998, the Company raised net
proceeds of $193.7 million in the Old Notes Offering.

control guidance systems for remotely-piloted vehicles, L-3 developed its
current family of strategic and tactical data links, including its Modular
Interoperable Data Link ("MIDL") systems and Modular Interoperable Surface
Terminals ("MIST"). MIDL and MIST technologies are considered virtual DoD
standards in terms of data link hardware. The Company's primary focus is spread
spectrum communication (based on CDMA technology), which involves transmitting
a data signal with a high rate noise signal so as to make it difficult to
detect by others, and then re-capturing the signal and removing the noise. The
Company's data links are capable of providing information at over 200 Mb/s.

     L-3 provides these secure high band width products to the U.S. Air Force,
Navy, Army and various Government agencies, many through long-term sole source
programs. The scope of these programs include air-to-ground, air-to-air,
ground-to-air and satellite communications. Government programs include: U-2
Support Program, Common High-Band Width Data Link ("CHBDL"), Battle Group
Passive Horizon Extension System ("BGPHES"), Light Airborne Multi-Purpose
System ("LAMPS"), TriBand SATCOM Subsystem ("TSS"), major unmanned aerial
vehicle ("UAV") programs and Direct Air-Satellite Relay ("DASR").


 o  SATELLITE COMMUNICATION TERMINALS

     L-3 provides ground-to-satellite, high availability, real-time global
communications capability through a family of transportable field terminals to
communicate with commercial, military and international satellites. These
terminals provide remote personnel with anywhere, anytime effective
communication capability and provide communications links to distant forces.
The Company's TriBand SATCOM Subsystem ("TSS") employs a 6.25 meter tactical
dish with a single point feed that provides C, Ku and X band communication to
support the U.S. Army. The Company also offers an 11.3 meter dish which is
transportable on two C-130 aircraft. The SHF Portable Terminal System ("PTS")
is a lightweight (28 lbs.), manportable terminal, which communicates through
DSCS, NATO or SKYNET satellites and brings unprecedented connectivity to small

Military applications include general procurement for test equipment or
electronic surveillance and countermeasure systems. Safety products are
instruments which are used to measure the level of non-ionizing radiation in a
given area, i.e., from an antenna, test set or other emitting source, and
determine whether human exposure limits are within federal standards.

     Narda West designs and manufactures state-of-the-art space-qualified and
wireless components. Space qualified components include channel amplifiers,
linearizers and diplexers/multiplexers, which are used to separate various
signals and direct them to the appropriate other sections of the payload. Narda
West's primary areas of focus are communications satellite payload products.
Channel amplifiers and linearizers constitute Narda West's main satellite
products. Channel amplifiers amplify the weak signals received from earth
stations by a factor of 1 million, and then drive the power amplifier tubes
that broadcast the signal back to earth. These products are sold to satellite
manufacturers and offer lower cost, lower weight and improved performance as
compared to in-house alternatives. On a typical satellite, for which there are
20 to 50 channel amplifiers, Narda West's channel amplifiers offer cost savings
of up to 60% (up to $1 million per satellite) and decrease launch weight by up
to 25 kilograms. Linearizers, used either in conjunction with a channel
amplifier or by themselves, pre-distort a signal to be transmitted back to
earth before it enters a Traveling Wave Tube ("TWT") for amplification. This
pre-distortion is exactly the opposite of the distortion created at peak power
by the TWT and, consequently, has a cancellation effect that keeps the signal
linear over a much larger power band of the tube. This sigificantly increases
the useful output power of the TWT and consequent terrestrial coverage from the
satellite.

     Narda West products include wireless microwave components for cellular and
PCS base station applications. These products include filters used to transmit
and receive channel separation as well as ferrite components which isolate
certain microwave functions, thereby preventing undesired signal interaction.
Other products include a wide variety of high reliability power splitters,
combiners and filters for spacecraft and launch vehicles, such as LLV, Tiros,
THAAD, Mars Surveyor, Peacekeeper, Galileo, Skynet, Cassini, Milstar, Space
Shuttle, LandSat, FltSatCom, GPS, GPS Block IIR, IUS, ACE, SMEX and certain
classified programs. The balance of the operation's business involves wideband
filters used for electronic warfare applications.

     DBS designs and manufactures both broad and narrow band amplifiers and
amplifier-based products in the microwave and millimeter wave frequencies.
These amplifiers are used as low-noise, high-gain components in defense and
communications applications. These devices can be narrow band for communication
needs or broadband for electronic warfare. DBS has an extensive offering of
amplifier designs allowing it to rapidly respond to unique requirements from
its marketplace.

     DBS offers standard packaged amplifiers for use in various automated test
equipment and system applications. It is also developing higher-level
assemblies for specific military applications in which the amplifier serves as
the cornerstone component. For future growth, DBS is at the forefront of
technology in both the design and manufacturing of millimeter range (-20GHz)
amplifier products for use in emerging communication applications such as back
haul radios, LMDS and ground terminals for LEOS. Further, DBS is starting to
penetrate the space qualified communications market with designs applicable to
many LEO communication satellite needs.

and airlines around the world. Recorders are mandated and regulated by various
worldwide agencies for commercial airlines and a large portion of business
aviation aircraft. Management anticipates growth opportunities in Aviation
Recorders as a result of the current high level of orders for new commercial
aircraft. Expansion into the military market shows continued growth
opportunities. L-3 Recorders were recently selected for installation on the
fleet of the Royal Australian Air Force and Royal Australian Army transport
aircraft and are currently being installed on the U.S. Navy C-9 aircraft. There
are two types of recorders: (i) the Cockpit Voice Recorder ("CVR") which
records the last 30 to 120 minutes of crew conversation and ambient sounds from
the cockpit and (ii) the Flight Data Recorder ("FDR") which records the last 25
hours of aircraft flight parameters such as speed, altitude, acceleration,
thrust from each engine and direction of the flight in its final moments.
Recorders are highly ruggedized instruments, designed to absorb the shock
equivalent to that of an object traveling at 268 knots stopping in 18 inches,
fire resistant to 1,100 degrees centigrade and pressure resistant to 20,000
feet undersea for 30 days. Management believes that the Company has the leading
worldwide market position for CVR's and FDR's.


 o  ANTENNA PRODUCTS

     Under the Randtron brand name, L-3 produces high performance antennas
designed for surveillance, high-resolution, ultra-wide frequency bands,
detection of low radar cross section ("LRCS") targets, LRCS installations,
severe environmental applications and polarization diversity. L-3's main
antenna product is a sophisticated 24-foot diameter antenna operational on all
E-2C aircraft. This airborne antenna consists of a 24-foot rotating aerodynamic
radome containing a UHF surveillance radar antenna, IFF antenna and forward and
aft auxiliary antennas. Production of this antenna began in the early 1980s,
and production is planned beyond 2000 for the E-2C, P-3 and C-130 AEW aircraft.
The replacement for this antenna is a very adaptive radar currently under
development for introduction early in the next decade. L-3 also produces
broad-band antennas for a variety of tactical aircraft and rotary joints for
the AWAC's and E-2C's antenna. Randtron has delivered over 2,000 aircraft sets
of antennas and has a current backlog through 1999. L-3 is a leading supplier
of ground-based radomes. Radomes are designed to enclose an antenna system as a
protective shield against the environment as well as to accentuate the
performance of an antenna system. Radomes are used to enclose antenna systems
used for air traffic control, weather radar, defense and scientific purposes.

TELEMETRY, INSTRUMENTATION AND SPACE PRODUCTS

     The Company is a leader in component products and systems used in
telemetry and instrumentation for airborne applications such as satellites,
aircraft, UAVs, launch vehicles, guided missiles, projectiles and targets.
Telemetry involves the collection of data from these platforms, its
transmission to ground stations for analysis, and its further dissemination or
transportation to another platform. A principal use of this telemetry data is
to measure as many as 1,000 different parameters of the platform's operation
(in much the same way as a flight data recorder on an airplane measures various
flight parameters) and transmit this data to the ground.

     Additionally, for satellite platforms, the equipment also acquires the
command uplink that controls the satellite and transmits the necessary data for
ground processing. In these applications, high reliability of components is
crucial because of the high cost of satellite repair and the length of
uninterrupted service required. Telemetry also provides the data to terminate
the flight of missiles and rockets under errant conditions and/or at the end of
a mission. Telemetry and command/control products are currently provided on
missile programs such as AMRAAM, ASRAAM, AIM-9X, JASSM, JDAM, FOTT, ATACMS and
PAC-3, as well as satellite programs such as GPS BLK IIF, GLOBALSTAR,
EARTHWATCH, SBIRS, LUNAR PROSPECTOR, MTSAT, ARTEMIS and Hughes ICO.


 o  AIRBORNE, GROUND AND SPACE TELEMETRY

     The Company provides airborne equipment and data link systems to gather
critical information and to process, format and transmit it to the ground
through communication data links from a communications satellite, spacecraft,
aircraft and/or missile. These products are available in both COTS and custom
configurations and include software and software engineering services. Major
customers are the major defense contractors who manufacture aircraft, missiles,
warheads, launch vehicles, munitions and bombs. Ground instrumentation activity
occurs at the ground station where the serial stream of combined data is
received and decoded in real-time, as it is received from the airborne
platform. Data can be encrypted and decrypted during this process, an
additional expertise that the Company offers. The Company recently introduced
the NeTstar satellite ground station, which collapses racks of satellite RF
receivers, demodulators and related units into a PC.


 o  SPACE PRODUCTS

     L-3 offers value-added solutions that require complex product integration,
rich software content and comprehensive support to its customers. The Company
focuses on the following niches within the satellite ground segment equipment
market: telephony, video broadcasting and multimedia. The Company's customers
include foreign PTT's, domestic and international prime communications
infrastructure contractors, telecommunications or satellite service providers,
broadcasters and media-related companies.

 o  WIRELESS LOOP TELECOMMUNICATIONS EQUIPMENT

     The Company is applying its wireless communication expertise to introduce
local wireless loop telecommunications equipment using a synchronous Code
Division Multiple Access technology ("CDMA") supporting terrestrial and space
based, fixed and mobile communication services. The system's principal targeted
customer base is emerging market countries and rural areas where existing
telecommunications infrastructure is inadequate or non-existent. The Company's
system will have the potential to interface with low earth orbit ("LEO") PCS
systems such as Globalstar, Iridium and/or any local public telephone network.
The Company expects to manufacture for sale certain of the infrastructure
equipment. The Company intends to pursue joint ventures with third parties for
service and distribution capabilities. The Company has entered into product
distribution agreements with Granger Telecom Ltd. for distribution in parts of
Africa, the Middle East and the United Kingdom, and with Unisys for
distribution in parts of Mexico and South America. This same technology is also
being introduced into the Ellipso "big LEO" program to provide the key
communications capability in the ground and user segments. In this program, the
Company will provide the CDMA processing equipment in the Ground Control
Segment and the Ellipso user terminals, both fixed and mobile.


 o  AIRPORT SECURITY EQUIPMENT

     The FAA has awarded the Company a development contract for next generation
airport security equipment for explosive detection. L-3 has teamed with
Analogic Corporation and GE to design and produce an explosive detection system
("EDS") utilizing a dual energy computer tomography ("CT") X-ray system. L-3's
EDS system, the eXaminer 3DX (Trade Mark)  6000, will analyze the contents of
checked baggage at airports for a wide-range of explosive material as specified
by the FAA. On November 23, 1998, L-3 received FAA certification for its
eXaminer 3DX (Trade Mark)  6000 system which is the only second- generation
system to receive certification and the only system to generate full,
three-dimensional images of all objects in a piece of baggage. The eXaminer 3DX
(Trade Mark)  6000 has been certified at 500 bags per hour but eventually will
be capable of inspecting baggage at an average of 675 bags per hour, which will
allow screening of passenger-checked baggage for a large body aircraft, such as
a Boeing 747, in approximately 40 minutes. It can be installed as a stand-alone
unit in a conveyor system or in a mobile van.


 o  INFORMATION NETWORK SECURITY

     The Company is applying its information security capabilites developed at
Communication Systems--East to the commercial markets through the formation of
a new subsidiary, L-3 Communications Secure Information Technology, Inc. ("L-3
Secure Information Technology").


                                       64
<PAGE>

Through a majority-owned joint venture ("L-3 Network Security"), L-3 Secure
Information Technology acquired a network security software business from
Trident Data Systems, which retained a minority interest in L-3 Network
Security.

     In early November 1998, L-3 Network Security announced the release of its
third-generation network security software, Expert (Trade Mark)  3.0, which
automates the sophisticated network risk analysis process. This software was
first developed for the U.S. Air Force and is now used by leading corporations,
consulting firms and government agencies. Expert (Trade Mark)  3.0 allows
network administrators and business managers to measure and manage information
risk by first automatically mapping a user's network, compiling a database of
all systems, applications and services -- including unauthorized modems. Expert
(Trade Mark)  3.0's risk algorithms then quantify the amount of risk present in
all parts of the network and analyze the likelihood of various insider and
outsider threats, linking these threats to actual vulnerabilities present on
the network. Expert (Trade Mark)  3.0's databases contain virtually all
publicly known computer vulnerabilities, researched and verified by L-3's
full-time security team. A comprehensive vulnerability report is provided by
Expert (Trade Mark)  3.0, which permits users to quantify risk measures and to
formulate a basis for information security policy.


MAJOR CUSTOMERS

     The Company's sales are predominantly derived from contracts with agencies
of, and prime contractors to, the Government. Various Government customers
exercise independent purchasing decisions. Sales to the Government generally
are not regarded as constituting sales to one customer. Instead, each
contracting entity is considered to be a separate customer. On a pro forma
basis, for the nine-month period ended September 30, 1998 the Company had
approximately 300 contracts with a value exceeding $1 million. Pro forma sales
to the Government for the nine-month period ended September 30, 1998, including
sales through prime contractors, were $608.1 million. The Company's largest
program is a long-term, sole source cost plus support contract for the U-2
program which contributed pro forma sales for the nine-month period ended
September 30, 1998 of approximately 7%. No other program represented more than
5% of such pro forma sales for the nine-month period ended September 30, 1998.
Sales to Lockheed Martin for the nine-month period ended September 30, 1998
were $51.1 million or approximately 7% of total sales.


RESEARCH AND DEVELOPMENT

     The Company employs scientific, engineering and other personnel to improve
its existing product lines and to develop new products and technologies in the
same or related fields. As of September 30, 1998, the Company employed
approximately 2,500 engineers (of whom more than 18% hold advanced degrees).
The pro forma amounts of research and development performed under
customer-funded contracts and Company-sponsored research projects, including
bid and proposal costs, for the nine-month period ended September 30, 1998 were
$166.8 million.


COMPETITION

     The Company's ability to compete for defense contracts depends to a large
extent on the effectiveness and innovativeness of its research and development
programs, its ability to offer better program performance than its competitors
at a lower cost to the Government customer, and its readiness in facilities,
equipment and personnel to undertake the programs for which it competes. In
some instances, programs are sole source or work directed by the Government to
a single supplier. In such cases, there may be other suppliers who have the
capability to compete for the programs involved, but they can only enter or
reenter the market if the Government should choose to reopen the particular
program to competition. Approximately 60% of the Company's $834.5 million pro
forma sales for the nine-month period ended September 30, 1998 were related to
sole source contracts.

     The Company experiences competition from industrial firms and U.S.
government agencies, some of which have substantially greater resources than
the Company. These competitors include: AlliedSignal, Cubic Corporation, Eaton
Corporation, Globecomm Systems Inc., Harris Corporation, Hughes, Motorola,
Scientific-Atlanta, Inc., Thomson Marconi Sonar Ltd., Titan Corporation and


                                       65
<PAGE>

TRW Inc. A majority of the sales of the Company is derived from contracts with
the Government and its prime contractors, and such contracts are awarded on the
basis of negotiations or competitive bids. Management does not believe any one
competitor or a small number of competitors is dominant in any of the business
areas of the Company. Management believes the Company will continue to be able
to compete successfully based upon the quality and cost competitiveness of its
products and services.


PATENTS AND LICENSES

     Although the Company owns some patents and has filed applications for
additional patents, it does not believe that its operations depend upon its
patents. In addition, the Company's Government contracts generally license it
to use patents owned by others. Similar provisions in the Government contracts
awarded to other companies make it impossible for the Company to prevent the
use by other companies of its patents in most domestic work.


BACKLOG

     As of September 30, 1998, the Company's pro forma funded backlog was
approximately $813.8 million. This backlog provides management with a useful
tool to project sales and plan its business on an on-going basis; however, no
assurance can be given that the Company's backlog will become revenues in any
particular period or at all. Funded backlog does not include the total contract
value of multi-year, cost-plus reimbursable contracts, which are funded as
costs are incurred by the Company. Funded backlog also does not include
unexercised contract options which represent the amount of revenue which would
be recognized from the performance of contract options that may be exercised by
customers under existing contracts and from purchase orders to be issued under
indefinite quantity contracts or basic ordering agreements. Overall,
approximately 72% of the Company's September 30, 1998 funded backlog is
expected to be shipped over the next twelve-month period. Our funded backlog as
of September 30, 1998 was made up of the following:

</TABLE>

GOVERNMENT CONTRACTS

     Approximately 68% of the Company's pro forma sales for the nine-month
period ended September 30, 1998 were made to agencies of the Government or to
prime contractors or subcontractors of the Government.

     Approximately 71% of the Company's pro forma sales mix of contracts for
the nine-month period ended September 30, 1998 were firm fixed price contracts
under which the Company agrees to perform for a predetermined price. Although
the Company's fixed price contracts generally permit the Company to keep
profits if costs are less than projected, the Company does bear the risk that
increased or unexpected costs may reduce profit or cause the Company to sustain
losses on the contract. Generally, firm fixed price contracts offer higher
margin than cost plus type contracts. All domestic defense contracts and
subcontracts to which the Company is a party are subject to audit, various
profit and cost controls and standard provisions for termination at the
convenience of the Government. Upon termination, other than for a contractor's
default, the contractor will normally be entitled to reimbursement for
allowable costs and to an allowance for profit. Foreign defense contracts
generally contain comparable provisions relating to termination at the
convenience of the government. To date, no significant fixed price contract of
the Company has been terminated.

     Companies supplying defense-related equipment to the Government are
subject to certain additional business risks peculiar to that industry. Among
these risks are the ability of the Government to unilaterally suspend the
Company from new contracts pending resolution of alleged violations of
procurement laws or regulations. Other risks include a dependence on
appropriations by the Government, changes in the Government's procurement
policies (such as greater emphasis on


                                       66
<PAGE>

competitive procurements) and the need to bid on programs in advance of design
completion. A reduction in expenditures by the Government for products of the
type manufactured by the Company, lower margins resulting from increasingly
competitive procurement policies, a reduction in the volume of contracts or
subcontracts awarded to the Company or substantial cost overruns would have an
adverse effect on the Company's cash flow.

approximately 3.0 million square feet of manufacturing facilities and
properties.


LEGAL PROCEEDINGS

     From time to time the Company is involved in legal proceedings arising in
the ordinary course of its business. Management believes it is adequately
reserved for these liabilities and that there is no litigation pending that
could have a material adverse effect on the Company's results of operations and
financial condition.


ENVIRONMENTAL MATTERS

     The Company's operations are subject to various federal, state and local
environmental laws and regulations relating to the discharge, storage,
treatment, handling, disposal and remediation of certain materials, substances
and wastes used in its operations. The Company continually assesses its
obligations and compliance with respect to these requirements. Management
believes that the Company's current operations are in substantial compliance
with all existing applicable environmental laws and permits. The Company does
not currently project the need for any material unbudgeted expenditures to
remain in compliance with applicable environmental laws and regulations.


                                       67
<PAGE>

     Pursuant to the L-3 Acquisition agreement, the Company has agreed to
assume certain on-site and off-site environmental liabilities related to events
or activities occurring prior to the L-3 Acquisition. Lockheed Martin has
agreed to retain all environmental liabilities for all facilities no longer
used by the Businesses and to indemnify fully the Company for such prior site
environmental liabilities. Lockheed Martin has also agreed, for the first eight
years following April 1997, to pay 50% of all costs incurred by the Company
above those reserved for on the Company's balance sheet at April 1997 relating
to certain Company-assumed environmental liabilities and, for the seven years
thereafter, to pay 40% of certain reasonable operation and maintenance costs
relating to any environmental remediation projects undertaken in the first
eight years. The Company is aware of environmental contamination at two of the
facilities acquired from Lockheed Martin that will require ongoing remediation.
In November 1997, the Company sold one such facility located in Sarasota,
Florida, while retaining a leasehold interest in a portion of that facility, to
DMB in a transaction in which DMB contractually agreed to assume responsibility
for further remediation of the Sarasota site. Management believes that the
Company has established adequate reserves for the potential costs associated
with the assumed environmental liabilities. However, there can be no assurance
that any costs incurred will be reimbursable from the Government or covered by
Lockheed Martin under the terms of the L-3 Acquisition agreement or that the
Company's environmental reserves will be sufficient.

     In connection with the acquisition of Ocean Systems, the Company has
acquired the stock of ELAC. In November 1998, the Company exercised its option
to purchase the ELAC property. The premises leased by ELAC at the time of the
acquisition have environmental contamination consisting of chlorinated solvents
in the groundwater beneath and adjoining the site. However, Honeywell Inc.
("Honeywell"), the previous owner of ELAC and the owner of the property at the
time of the acquisition, has retained the liability for remediating the ELAC
site and has contractually agreed to indemnify AlliedSignal and ELAC.
Management believes that any necessary remediation will be covered by the
Honeywell indemnification.

     In connection with the acquisition of STS, the Company acquired certain
facilities located in Hauppauge, New York. As part of the acquisition,
California Microwave agreed to retain liability for environmental contamination
occurring prior to the closing date. Subsequent to the acquisition, the Company
performed an environmental assessment of the ground water beneath the site and
determined that the ground water contained chlorinated solvents used by STS
only prior to the closing of the STS acquisition. The Company has tendered the
defense of this matter to California Microwave, which is performing a further
investigation of the ground water contamination. Management believes that any
necessary remediation will be covered by an indemnification from California
Microwave.


PENSION PLANS

     Pursuant to the L-3 Acquisition agreement, Holdings and L-3 Communications
assumed certain liabilities relating to defined benefit pension plans for
present and former employees and retirees of certain businesses which were
transferred from Lockheed Martin to Holdings and L-3 Communications. Prior to
the consummation of the L-3 Acquisition, Lockheed Martin received a letter from
the PBGC which requested information regarding the transfer of such pension
plans and indicated that the PBGC believed certain of such pension plans were
underfunded using the PBGC's actuarial assumptions (which assumptions result in
a larger liability for accrued benefits than the assumptions used for financial
reporting under FASB 87.) The PBGC underfunding is related to the Subject
Plans. As of September 30, 1998, the Company calculated the net funding
position of the Subject Plans and believes them to be overfunded by
approximately $4.8 million under the Employee Retirement Income Security Act of
1974, as amended ("ERISA") assumptions, underfunded by approximately $28.4
million under FASB 87 assumptions and, on a termination basis, underfunded by
as much as $70.4 million under PBGC assumptions.

     With respect to the Subject Plans, Lockheed Martin entered into an
agreement (the "Lockheed Martin Commitment Agreement") among Lockheed Martin,
L-3 and the PBGC dated as of April 30, 1997. The material terms and conditions
of the Lockheed Martin Commitment Agreement include a


                                       68
<PAGE>

commitment by Lockheed Martin to the PBGC to, under certain circumstances,
assume sponsorship of the Subject Plans or provide another form of financial
support for the Subject Plans. The Lockheed Martin Commitment Agreement will
continue with respect to any Subject Plan until such time as such Subject Plan
is no longer underfunded on a PBGC basis for two consecutive years or, at any
time after May 31, 2002, the Company achieves investment grade credit ratings.
Pursuant to the Lockheed Martin Commitment Agreement, the PBGC agreed that it
would take no further action in connection with the L-3 Acquisition.

   
     In return for the Lockheed Martin Commitment, the Company entered into an
agreement with Lockheed Martin, dated as of April 30, 1997, pursuant to which
the Company provided certain assurances to Lockheed Martin including, but not
necessarily limited to, (i) continuing to fund the Subject Plans consistent
with prior practices and to the extent deductible for tax purposes and, where
appropriate, recoverable under Government contracts, (ii) agreeing to not
increase benefits under the Subject Plans without the consent of Lockheed
Martin, (iii) restricting the Company from a sale of any businesses employing
individuals covered by the Subject Plans if such sale would not result in
reduction or elimination of the Lockheed Martin Commitment with regard to the
specific plan and (iv) if the Subject Plans were returned to Lockheed Martin,
granting Lockheed Martin the right to seek recovery from the Company of those
amounts actually paid, if any, by Lockheed Martin with regard to the Subject
Plans after their return. In addition, upon the occurrence of certain events,
Lockheed Martin, at its option, has the right to decide whether to cause the
Company to transfer sponsorship of any or all of the Subject Plans to Lockheed
Martin, even if the PBGC has not sought to terminate the Subject Plans.
Lockheed Martin may exercise this right by giving 45 days prior written notice
to the Company after the occurrence of such triggering events if it has
concluded that the liabilities of the Subject Plans would increase
unreasonably. As a result of a decrease in the PBGC-mandated discount rate and
the resulting decrease in the underlying liability, one of such triggering
events has occurred. The Company has notified Lockheed Martin of this fact.
Lockheed Martin has informed the Company that it has no present intention to
exercise its right to cause the Company to transfer sponsorship of the Subject
Plans. If Lockheed Martin did assume sponsorship of these plans, it would be
primarily liable for the costs associated with funding the Subject plans or any
costs associated with the termination of the Subject Plans but the Company
would be required to reimburse Lockheed Martin for these costs. To date, the
impact on pension expense and funding requirements resulting from this
arrangement has not been significant. However, should Lockheed Martin resume
sponsorship of the Subject Plans or if these plans were terminated, the impact
of any increased pension expenses or funding requirements could be material to
the Company. The Company has performed its obligations under the letter
agreement with Lockheed Martin and the Lockheed Martin Commitment and has not
received any communications from the PBGC concerning actions which the PBGC
contemplates taking in respect of the Subject Plans.
    


EMPLOYEES

   
     As of December 31, 1998, the Company employed approximately 8,000
full-time and part-time employees. The Company believes that its relations with
its employees are good.
    

     Approximately 540 of the Company's employees at its Communication
Systems--East operation in Camden, New Jersey are represented by four unions,
the Association of Scientists and Professional Engineering Personnel, the
International Federation of Professional and Technical Engineers, the
International Union of Electronic, Electrical, Salaried, Machine and Furniture
Workers and an affiliate of the International Brotherhood of Teamsters. The
collective bargaining agreements for these four unions were successfully
renegotiated in mid-1998 without any disruptions to operations. Three of the
collective bargaining agreements will expire in 2002, and the other agreement
will expire in 2001.

     Approximately 200 employees of Ocean Systems are represented by the United
Auto Workers. The collective bargaining agreement expires in mid-1999.
Approximately 140 of the employees at Ocean Systems' ELAC subsidiary in Kiel,
Germany are represented by the Metal Trade Industrial Workers of the Hamburg
Region and ELAC is represented by the Association of Metal Industry Employers
for Schleswig-Holstein. While the Company has not yet initiated discussions
with representatives of the United Auto Workers, management believes it will be
able to negotiate, without


                                       69
<PAGE>

material disruption to its business, a satisfactory new labor contract with
these employees. However, there can be no assurance that a satisfactory
agreement will be reached with the covered employees or that a material
disruption to operations of Ocean Systems will not occur.


     Approximately 350 of SPD's employees located in Philadelphia, Pennsylvania
are represented by the United Automobile Aerospace and Agricultural Implement
Workers of America, Local 1612 Amalgamated. The four collective bargaining
agreements covering these employees expire in early April 1999, following a six
year labor agreement. While the Company has not yet initiated discussions with
representatives of the union, management believes that it will be able to
negotiate, without material disruption to its business, satisfactory new
collective bargaining agreements. However, there can be no assurance that a
satisfactory agreement will be reached with the covered employees or that a
material disruption to the Company's Philadelphia operations will not occur.
Approximately 20 of SPD's employees located in Anaheim and National City,
California are represented by the International Brotherhood of Electrical
Workers, Local 569, whose collective bargaining agreement expires in late May
2000 and approximately 20 employees are represented by the International
Association of Machinists and Aerospace Workers, Local 389 whose collective
bargaining agreement expires in early February 2000.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Under the L-3 Acquisition agreement, Lockheed Martin has agreed to
indemnify L-3, subject to certain limitations, for Lockheed Martin's breach of
representations and warranties and L-3 has assumed certain obligations relating
to environmental matters and benefits plans. These obligations include certain
on-site and off-site environmental liabilities related to events or activities
of the Businesses occurring prior to the L-3 Acquisition. Lockheed Martin has
agreed to indemnify Holdings, subject to certain limitations, for its breach of
(i) non-environmental representations and warranties up to $50 million (subject
to a $5 million threshold) and (ii) for the first eight years following April
1997, to pay 50% of all costs incurred by the Company above those reserved for
on the Company's balance sheet at April 1997 relating to certain
Company-assumed environmental liabilities and, for the seven years thereafter,
40% of certain reasonable operation and maintenance costs relating to any
environmental remediation projects undertaken in the first eight years (subject
to a $6 million threshold).

     Lockheed Martin provides to certain divisions of the Company certain
management information systems services at Lockheed Martin's fully-burdened
cost but without profit. Holdings, L-3 Communications and Lockheed Martin have
entered into certain subleases of real property and cross-licenses of
intellectual property.

     In addition, Holdings and Lockheed Martin have entered into a Limited
Noncompetition Agreement (the "Noncompetition Agreement") which, for up to
three years from April 1997, in certain circumstances, precludes Lockheed
Martin from engaging in the sale of any products that compete with the products
of the Company that are set forth in the Noncompetition Agreement for
specifically identified application of the products. Under the Noncompetition
Agreement, Lockheed Martin is prohibited, with certain exceptions, from
acquiring any business engaged in the sale of the specified products referred
to in the preceding sentence, although Lockheed Martin may acquire such a
business under circumstances where the exceptions do not apply provided that it
offers to sell such business to L-3 within 90 days of its acquisition. The
Noncompetition Agreement does not, among other exceptions, (i) apply to
businesses operated and managed by Lockheed Martin on behalf of the Government,
(ii) prohibit Lockheed Martin from engaging in any existing businesses and
planned businesses as of the closing of the L-3 Acquisition or businesses that
are reasonably related to existing or planned businesses or (iii) apply to
selling competing products where such products are part of a larger system sold
by Lockheed Martin.

     In the ordinary course of business L-3 sells products to Lockheed Martin
and its affiliates. Sales to Lockheed Martin were $51.1 million, $81.6 million,
$70.7 million and $25.9 million for the nine-month period ended September 30,
1998 and the years ended December 31, 1997, 1996 and 1995, respectively. See
Note 19 to the Consolidated (Combined) Financial Statements.

     Sales of products to Lockheed Martin, excluding those under existing
intercompany work transfer agreements, are made on terms no less favorable than
those which would be available from non-affiliated third party customers. A
significant portion of L-3's sales to Lockheed Martin are either based on
competitive bidding or catalog prices.


STOCKHOLDERS AGREEMENT

     Holdings, Lockheed Martin, the Lehman Partnership and Messrs. Lanza and
LaPenta entered into a stockholders agreement (the "Stockholders Agreement")
which, except for the terms relating to (i) the registration rights, (ii)
provision of services by Lehman Brothers and (iii) the standstill agreement by
Lockheed Martin, terminated upon the completion of the IPO.

   
     Pursuant to the Stockholders Agreement, Messrs. Lanza and LaPenta,
Lockheed Martin and the Lehman Partnership have the right, from time to time
and subject to certain conditions, to require Holdings to register under the
Securities Act shares of common stock held by them. Lockheed Martin, the Lehman
Partnership and each of the Senior Management has three, four and one demand
registration rights, respectively. In addition, the Stockholders Agreement also
provides certain existing stockholders with certain piggyback registration
rights. The Stockholders Agreement provides, among
    


                                       71
<PAGE>

other things, that the Company will pay expenses in connection with (i) up to
two demand registrations requested by Lockheed Martin, up to three demand
registrations requested by the Lehman Partnership and the two demand
registrations requested by the Senior Management and (ii) any registration in
which the existing stockholders participate through piggyback registration
rights granted under such agreement.


     The Stockholders Agreement also provides that Lehman Brothers Inc. has the
exclusive right to provide investment banking services to Holdings for the
five-year period after the closing of the L-3 Acquisition (except that the
exclusivity period is three years as to cash acquisitions undertaken by L-3) so
long as the Lehman Partnership owns at least 10% of Holdings' outstanding
common stock. In the event that Lehman Brothers Inc. agrees to provide any
investment banking services to L-3, it will be paid fees that are mutually
agreed upon based on similar transactions and practices in the investment
banking industry.


     Under the Stockholders Agreement Lockheed Martin is subject to a
standstill arrangement which generally prohibits any increase in its share
ownership percentage over 34.9%.

of Directors divided into three classes. Class I will expire at the annual
meeting of the stockholders to be held in 1999; Class II will expire at the
annual meeting of the stockholders to be held in 2000; and Class III will
expire at the annual meeting of the stockholders to be held in 2001. At each
annual meeting of the stockholders, beginning with the 1999 annual meeting, the
successors to directors whose terms will then expire will be elected to serve
from the time of election and qualification until the third annual meeting
following election and until their successors have been duly elected and
qualified, or until their earlier resignation or removal, if any. To the extent
there is an increase or reduction in the number of directors, increase or
decrease in directorships resulting therefrom will be distributed among the
three classes so that, as nearly as possible, each class will consist of an
equal number of directors.

     Each executive officer and key employee serves at the discretion of the
Board of Directors.


COMMITTEES OF THE BOARD OF DIRECTORS

     The Board of Directors has two standing committees: an Audit Committee and
a Compensation Committee. Currently, the Audit Committee consists of Messrs.
Brand, Fried and Menaker. The Company intends to appoint to the Audit Committee
only persons who qualify as an "independent" director for purposes of the rules
and regulations of the NYSE. The Audit Committee selects and engages, on behalf
of the Company, the independent public accountants to audit the Company's
annual financial statements, and reviews and approves the planned scope of the
annual audit. Currently, Messrs. Millard, Montague and Washkowitz serve as
members of the Compensation Committee. The Compensation Committee establishes
remuneration levels for certain officers of the Company, performs such
functions as provided under the Company's employee benefit programs and
executive compensation programs and administers the 1997 Option Plan for Key
Employees of Holdings.


COMPENSATION OF DIRECTORS

     The affiliated directors of the Company do not receive compensation for
their services as directors. The non-affiliated directors will receive annual
compensation of $25,000 in cash, $5,000 of Holdings' common stock, and a grant
of stock options to 1,500 shares of Holdings common stock. The non-affiliated
directors are entitled to reimbursement for their reasonable out-of-pocket
expenses in connection with their travel to and attendance at meetings of the

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS


     The Company's certificate of incorporation provides that to the fullest
extent permitted by the Delaware General Corporation Law (the "DGCL"), a
director of the Company shall not be liable to the Company or its stockholders
for monetary damages for breach of fiduciary duty as a director. Under the
DGCL, liability of a director may not be limited (i) for any breach of the
director's duty of loyalty to the Company or its stockholders, (ii) for acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law, (iii) in respect of certain unlawful dividend payments or
stock redemptions or repurchases and (iv) for any transaction from which the
director derives an improper personal benefit. The effect of the provisions of
the Company's certificate of incorporation is to eliminate the rights of the
Company and its stockholders (through stockholders' derivative suits on behalf
of the Company) to recover monetary damages against a director for breach of
the fiduciary duty of care as a director (including breaches resulting from
negligent or grossly negligent behavior), except in the situations described in
clauses (i) through (iv) above. This provision does not limit or eliminate the
rights of the Company or any stockholder to seek nonmonetary relief such as an
injunction or rescission in the event of a breach of a director's duty of care.
In addition, the Company's bylaws provide that the Company shall indemnify its
directors, officers, employees and agents against losses incurred by any such
person by reason of the fact that such person was acting in such capacity.


     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that, in
the opinion of the Commission, such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

- ----------
(1)   The grant-date valuation of the options was calculated using the minimum
      value method described in SFAS No. 123. The minimum value is computed as
      the current price of stock at grant date reduced to exclude the present
      value of any expected dividends during the option's expected life minus
      the present value of the exercise price, and does not consider the
      expected volatility of the price of the stock underlying the option. The
      material assumptions underlying the computations are: an average discount
      rate of 6.3%; a dividend yield of 0% and a weighted average expected
      option life of 5.49 years, with the option lives ranging from 2 years to
      10 years.

(2)   Half of the options granted consists of Time Options and half consists of
      Performance Options. See "-- Employment Agreements" for description of
      the terms of these options.

Summary Compensation Table.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Board of Directors of Holdings established a Compensation Committee in
June 1997. During the 1997 fiscal year, Messrs. Robert Millard, Steven Berger
and John Montague served as members of the Compensation Committee. None of
these individuals has served at any time as an officer or employee of Holdings
or L-3 Communications. Mr. Berger resigned from Holdings' Board of Directors
and the Compensation Committee in January 1998 and Mr. Washkowitz was appointed
to the Compensation Committee in March 1998. Prior to the establishment of the
Compensation Committee, all decisions relating to executive compensation were
made by Holdings' Board of Directors. Messrs. Millard and Washkowitz are
affiliated with the Lehman Partnership which holds 36.6% of the Holdings common
stock (prior to the Proposed Equity Offering) and is a party to the
Stockholders Agreement. Pursuant to the Stockholders Agreement, the Lehman
Partnership has the right, from time to time subject to certain conditions, to
require Holdings to register under the Securities Act shares of its common
stock held by them. The Lehman Partnership has the right to request up to four
demand registrations and also has piggyback registration rights. Holdings has
agreed in the Stockholders Agreement to pay expenses in connection with, among
other things, (i) up to three demand registrations requested by the Lehman
Partnership and (ii) any registration in which the existing stockholders
participate through piggyback registration rights granted under such agreement.
The Stockholders Agreement also provides that Lehman Brothers Inc. has the
exclusive right to provide investment banking services to Holdings for the
five-year period after the closing of the L-3 Acquisition (except that the
exclusivity period is three years as to cash acquisitions undertaken by L-3) so
long as the Lehman Partnership owns at least 10% of the outstanding Holdings
common stock. In the event that Lehman Brothers Inc. agrees to provide any
investment banking services to L-3, it will be paid fees that are mutually
agreed upon based on similar transactions and practices in the investment
banking industry.

     No executive officer of Holdings or L-3 Communications serves as a member
of the board of directors or compensation committee of any entity which has one
or more executive officers serving as a member of Holdings' Board of Directors
or Compensation Committee.


1997 STOCK OPTION PLAN

     In April 1997, Holdings adopted the 1997 Option Plan for Key Employees of
Holdings (the "1997 Stock Option Plan") which authorizes the Compensation
Committee to grant options to key employees of Holdings and its subsidiaries.
On March 10, 1998, the 1997 Stock Option Plan was amended to increase the
shares available for option grants to 4,255,815 shares of common stock, of


                                       79
<PAGE>

   
which 3,400,794 had been granted and were outstanding as of December 31, 1998.
The Compensation Committee of the Board of Directors of Holdings, in its sole
discretion, determines the terms of option agreements, including without
limitation the treatment of option grants in the event of a change of control.
The 1997 Stock Option Plan remains in effect for 10 years following the date of
approval.

     On April 30, 1997, Holdings granted each of Messrs. Lanza and LaPenta
options to purchase 1,142,857 shares of common stock. See "-- Employment
Agreements" for a description of the terms of these grants. On July 1, 1997 and
November 11, 1997, the Compensation Committee authorized grants of options to
employees of Holdings and its subsidiaries, other than Messrs. Lanza and
LaPenta, to acquire an aggregate of 689,500 shares of common stock at an
exercise price of $6.47 per share (the "Employee Options"). Each Employee
Option was granted pursuant to an individual agreement that provides (i) 20% of
shares underlying the option will become exercisable on the first anniversary
of the grant date, 50% will become exercisable on the second anniversary of the
grant date and 30% will become exercisable on the third anniversary of the
grant date; provided that, after the IPO 15% of the shares underlying the
option (which would otherwise become exercisable on the second anniversary of
the grant date) became exercisable; (ii) all shares underlying the option will
become exercisable upon certain events constituting a change of control; and
(iii) the option will expire upon the earliest to occur of (A) the tenth
anniversary of the grant date, (B) one year after termination of employment due
to the optionee's death or permanent disability, (C) immediately upon
termination of the optionee's employment for cause and (D) three months after
termination of optionee's employment for any other reason. On March 2, 1998,
each of Mr. Lanza and Mr. LaPenta exercised options to acquire 228,571 shares
of common stock. On May 1, 1998, Holdings granted options to employees of
Holdings and its subsidiaries, other than Messrs. Lanza and LaPenta, to
purchase 282,880 shares of common stock at an exercise price of $22.00 per
share and on terms substantially similar to the Employee Options. On August 13,
1998, Holdings granted options to purchase 142,200 shares of common stock at an
exercise price of $32.75 per share primarily to employees of recently acquired
companies. The terms of such stock options were substantially similar to the
Employee Options except that such options vest in equal installments over a
period of three years.
    


EMPLOYMENT AGREEMENTS

     Holdings entered into an employment agreement (the "Employment
Agreements") effective on April 30, 1997 with each of Mr. Lanza, Chairman and
Chief Executive Officer of Holdings and L-3 Communications, who will receive a
base salary of $750,000 per annum and appropriate executive level benefits, and
Mr. LaPenta, President and Chief Financial Officer of Holdings and L-3
Communications, who will receive a base salary of $500,000 per annum and
appropriate executive level benefits. The Employment Agreements provide for an
initial term of five years, which will automatically renew for one-year periods
thereafter, unless a party thereto gives notice of its intent to terminate at
least 90 days prior to the expiration of the term.

     Upon a termination without cause or resignation for good reason, Holdings
will be obligated, through the end of the term, to (i) continue to pay the base
salary and (ii) continue to provide life insurance and medical and
hospitalization benefits comparable to those provided to other senior
executives; provided, however, that any such coverage shall terminate to the
extent that Mr. Lanza or Mr. LaPenta, as the case may be, is offered or obtains
comparable benefits coverage from any other employer. The Employment Agreements
provide for confidentiality during employment and at all times thereafter.
There is also a noncompetition and non-solicitation covenant which is effective
during the employment term and for one year thereafter; provided, however, that
if the employment terminates following the expiration of the initial term, the
noncompetition covenant will only be effective during the period, if any, that
Holdings pays the severance described above.

     Holdings has granted each of Messrs. Lanza and LaPenta (together, the
"Equity Executives") nonqualified options to purchase, at $6.47 per share of
Holdings' common stock, 1,142,857 shares of Holdings' initial fully-diluted
common stock. In each case, half of the options will be "Time Options" and half
will be "Performance Options" (collectively, the "Options"). The Time Options
became


                                       80
<PAGE>

exercisable with respect to 20% of the shares subject to the Time Options on
March 2, 1998 and will become exercisable each of the second through fifth
anniversaries of the closing of the L-3 Acquisition (the "Closing") if
employment continues through and including such date. The Performance Options
will become exercisable nine years after the Closing, but became exercisable
with respect to up to 20% of the shares subject to the Performance Options on
March 2, 1998 and will become exercisable each of the second through fifth
anniversaries of the Closing, to the extent certain EBITDA targets are
achieved. The Options will become fully exercisable under certain
circumstances, including a change in control. The Option term is ten years from
the Closing; except that if (i) the Equity Executive is fired for cause or
resigns without good reason, the Options will expire upon termination of
employment or (ii) the Equity Executive is fired without cause, resigns for
good reason, dies, becomes disabled or retires, the Options will expire one
year after termination of employment. Unexercisable Options will terminate upon
termination of employment, unless acceleration is expressly provided for. Upon
a change of control, Holdings may terminate the Options, so long as the Equity
Executives are cashed out or permitted to exercise their Options prior to such
change of control.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS



SENIOR CREDIT FACILITIES

     The Senior Credit Facilities have been provided by a syndicate of banks
led by Bank of America National Trust & Savings Association, as administrative
agent. The Senior Credit Facilities provide for (A) $200 million in revolving
credit loans which must be repaid by March 31, 2003 (the "Revolving Credit
Facility") and (B) $185 million in revolving credit loans which must be repaid
by August 12, 1999 (the "Revolving 364 Day Facility" and together with the
Revolving Credit Facility, the "Senior Credit Facilities"); provided that all
or a portion of the Revolving 364 Day Facility may be extended for a period of
364 days following August 12, 1999 with the consent of lenders holding not less
than 50% of the commitments to make 364-day loans (August 12, 1999 or the date
364 days thereafter, the "364 Day Termination Date"); and provided further that
L-3 Communications may convert the outstanding principal amount of any or all
of the loans outstanding under the Revolving 364 Day Facility to term loans on
the 364 Day Termination Date. The Revolving Credit Facility includes borrowing
capacity available for letters of credit and for borrowings on same-day notice
(the "Swingline Loans").

     All borrowings under the Senior Credit Facilities bear interest, at L-3
Communications' option, at either: (A) a "base rate" equal to, for any day, the
higher of: (a) 0.50% per annum above the latest Federal Funds Rate; and (b) the
rate of interest in effect for such day as publicly announced from time to time
by Bank of America National Trust & Savings Association in San Francisco,
California, at its "reference rate" plus a spread ranging from 0.875% to 0.0%
per annum depending on the Company's ratio of debt to EBITDA (as defined in the
Senior Credit Facilities ("Bank EBITDA")) at the time of determination or (B) a
"LIBOR rate" equal to, for any Interest Period (as defined in the Senior Credit
Facilities), the London interbank offered rate of interest per annum for such
Interest Period as determined by the administrative agent, plus a spread
ranging from 1.875% to 0.625% per annum, depending on the Company's ratio of
debt to Bank EBITDA at the time of determination, provided that Swingline Loans
can only bear interest at a "base rate" plus the applicable spread.

     L-3 Communications will pay commitment fees calculated at a rate (A)
ranging from 0.50% to 0.25% per annum on the daily amount of the available
unused commitment under the Revolving Credit Facility and (B) ranging from
0.30% to 0.125% per annum on the daily amount of the available unused
commitment under the Revolving 364 Day Facility, in each case depending on the
Company's ratio of debt to Bank EBITDA in effect on each day. Such commitment
fees will be payable quarterly in arrears and upon termination of the Senior
Credit Facilities.

     L-3 Communications will pay a letter of credit fee calculated at a rate
ranging from (A) 0.9375% to 0.3125% per annum in the case of performance
letters of credit and (B) 1.875% to 0.625% in the case of all other letters of
credit, in each case depending on the Company's ratio of debt to Bank EBITDA at
the time of determination. L-3 Communications will also pay a fronting fee
equal to 0.1250% per annum on the aggregate face amount of all outstanding
letters of credit. Such fees will be payable quarterly in arrears and upon the
termination of the Senior Credit Facilities. In addition, L-3 Communications
will pay customary transaction charges in connection with any letters of
credit. The Senior Credit Facilities provide for the issuance of letters of
credit in currencies other than United States dollars.

     The foregoing debt to Bank EBITDA-dependent rates range from the highest
rate specified if the ratio of debt to Bank EBITDA is greater than 4.75 to 1.0
and the lowest rate specified if such ratio is less than 2.75 to 1.0.

     In the event that the 364 Day loans are converted into term loans, such
term loans shall be repaid by the Borrower in nine (9) consecutive quarterly
installment commencing on March 31, 2001, by funding on each amortization
payment date set forth below an amount necessary to cause the aggregate
principal amount of term loans outstanding on such date to not exceed an amount
equal to the product of (x) the "Applicable Percentage" set forth opposite such
amortization payment date


                                       83

multiplied by (y) the aggregate amount of commitments of lenders to make loans
under the Revolving 364 Day Facility on the 364 Day Termination Date (the
"Applicable Converted Commitment"):

     Borrowings under the Senior Credit Facilities are subject to mandatory
prepayment (i) with the net proceeds of any incurrence of indebtedness and (ii)
with the proceeds of asset sales, in both cases subject to certain exceptions.

     L-3 Communications' obligations under the Senior Credit Facilities are
secured by (i) a pledge by Holdings of the stock of L-3 Communications and (ii)
a pledge by L-3 Communications and its material direct and indirect
subsidiaries of all of the stock of their respective material domestic
subsidiaries and 65% of the stock of L-3 Communications' material first-tier
foreign subsidiaries. In addition, indebtedness under the Senior Credit
Facilities is guaranteed by Holdings and by all of L-3 Communications' direct
and indirect material domestic subsidiaries.

     The Senior Credit Facilities contain customary covenants and restrictions
on L-3 Communications' ability to engage in certain activities. In addition,
the Senior Credit Facilities provide that L-3 Communications must meet or
exceed an interest coverage ratio and must not exceed a leverage ratio. The
Senior Credit Facilities also include customary events of default.

                              THE EXCHANGE OFFER


GENERAL

     The Company hereby offers, upon the terms and subject to the conditions
set forth in this prospectus and in the accompanying Letter of Transmittal
(which together constitute the Exchange Offer), to exchange up to $200 million
aggregate principal amount of Exchange Notes for a like aggregate principal
amount of Old Notes properly tendered on or prior to the Expiration Date and
not withdrawn as permitted pursuant to the procedures described below. The
Exchange Offer is being made with respect to all of the Old Notes.

   
     As of the date of this prospectus, $200 million aggregate principal amount
of the Old Notes is outstanding. This prospectus, together with the Letter of
Transmittal, is first being sent on or about January 20, 1999, to all holders
of Old Notes known to the Company. The Company's obligation to accept Old Notes
for exchange pursuant to the Exchange Offer is subject to certain conditions
set forth under "Certain Conditions to the Exchange Offer" below. The Company
currently expects that each of the conditions will be satisfied and that no
waivers will be necessary.
    


PURPOSE OF THE EXCHANGE OFFER

     The Old Notes were issued on December 11, 1998 (the "Issuance Date") in a
transaction exempt from the registration requirements of the Securities Act.
Accordingly, the Old Notes may not be reoffered, resold, or otherwise
transferred unless so registered or unless an applicable exemption from the
registration and prospectus delivery requirements of the Securities Act is
available.

     In connection with the issuance and sale of the Old Notes, the Company
entered into the Registration Rights Agreement, which requires the Company to
file with the Commission a registration statement relating to the Exchange
Offer not later than 90 days after the date of issuance of the Old Notes, and
to use its best efforts to cause the registration statement relating to the
Exchange Offer to become effective under the Securities Act not later than 150
days after the date of issuance of the Old Notes and the Exchange Offer to be
consummated not later than 30 days after the date of the effectiveness of the
Registration Statement (or, if obligated to file a shelf registration
statement, to use its best efforts to file the shelf registration statement
with the Commission within 30 days after such filing obligation arises and to
cause the shelf registration statement to be declared effective within 90 days
after such obligation arises). A copy of the Registration Rights Agreement has
been filed as an exhibit to the Registration Statement.

     The Exchange Offer is being made by the Company to satisfy its obligations
with respect to the Registration Rights Agreement. The term "holder," with
respect to the Exchange Offer, means any person in whose name Old Notes are
registered on the books of the Company or any other person who has obtained a
properly completed bond power from the registered holder, or any person whose
Old Notes are held of record by The Depository Trust Company. Other than
pursuant to the Registration Rights Agreement, the Company is not required to
file any registration statement to register any outstanding Old Notes. Holders
of Old Notes who do not tender their Old Notes or whose Old Notes are tendered
but not accepted would have to rely on exemptions to registration requirements
under the securities laws, including the Securities Act, if they wish to sell
their Old Notes.

     The Company is making the Exchange Offer in reliance on the position of
the staff of the Commission as set forth in certain interpretive letters
addressed to third parties in other transactions. However, the Company has not
sought its own interpretive letter and there can be no assurance that the staff
would make a similar determination with respect to the Exchange Offer as it has
in such interpretive letters to third parties. Based on these interpretations
by the Staff, the Company believes that the Exchange Notes issued pursuant to
the Exchange Offer in exchange for Old Notes may be offered for resale, resold
and otherwise transferred by a Holder (other than any Holder who is a
broker-dealer or an "affiliate" of the Company within the meaning of Rule 405
of the Securities Act) without further compliance with the registration and
prospectus delivery requirements of the


                                       87
<PAGE>

Securities Act, provided that such Exchange Notes are acquired in the ordinary
course of such Holder's business and that such Holder is not participating, and
has no arrangement or understanding with any person to participate, in a
distribution (within the meaning of the Securities Act) of such Exchange Notes.
See "-- Resale of Exchange Notes". Each broker-dealer that receives Exchange
Notes for its own account in exchange for Old Notes, where such Old Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. See "Plan of Distribution".


TERMS OF THE EXCHANGE

     The Company hereby offers to exchange, subject to the conditions set forth
herein and in the Letter of Transmittal accompanying this prospectus, $1,000 in
principal amount of Exchange Notes for each $1,000 in principal amount of the
Old Notes. The terms of the Exchange Notes are identical in all material
respects to the terms of the Old Notes for which they may be exchanged pursuant
to this Exchange Offer, except that the Exchange Notes will generally be freely
transferable by holders thereof and will not be subject to any covenant
regarding registration. The Exchange Notes will evidence the same indebtedness
as the Old Notes and will be entitled to the benefits of the Indenture. See
"Description of the Exchange Notes".

     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered for exchange.

     The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the
Exchange Notes issued pursuant to the Exchange Offer in exchange for the Old
Notes may be offered for sale, resold or otherwise transferred by any holder
without compliance with the registration and prospectus delivery provisions of
the Securities Act. Instead, based on an interpretation by the staff of the
Commission set forth in a series of no-action letters issued to third parties,
the Company believes that Exchange Notes issued pursuant to the Exchange Offer
in exchange for Old Notes may be offered for sale, resold and otherwise
transferred by any holder of such Exchange Notes (other than any such holder
that is a broker-dealer or is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such holder's business
and such holder has no arrangement or understanding with any person to
participate in the distribution of such Exchange Notes and neither such holder
nor any other such person is engaging in or intends to engage in a distribution
of such Exchange Notes. Since the Commission has not considered the Exchange
Offer in the context of a no-action letter, there can be no assurance that the
staff of the Commission would make a similar determination with respect to the
Exchange Offer. Any holder who is an affiliate of the Company or who tenders in
the Exchange Offer for the purpose of participating in a distribution of the
Exchange Notes cannot rely on such interpretation by the staff of the
Commission and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
Each holder, other than a broker-dealer, must acknowledge that it is not
engaged in, and does not intend to engage in, a distribution of Exchange Notes.
Each broker-dealer that receives Exchange Notes for its own account in exchange
for Old Notes, where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes. See "Plan of Distribution".

     Interest on the Exchange Notes will accrue from the last Interest Payment
Date on which interest was paid on the Old Notes so surrendered or, if no
interest has been paid on such Notes, from December 11, 1998.

     Tendering holders of the Old Notes shall not be required to pay brokerage
commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of the Old Notes
pursuant to the Exchange Offer.

EXPIRATION DATE; EXTENSION; TERMINATION; AMENDMENT

   
     The Exchange Offer will expire at 5:00 p.m., New York City time, on
February 19, 1999, unless the Company, in its sole discretion, has extended the
period of time for which the Exchange Offer is open (such date, as it may be
extended, is referred to herein as the "Expiration Date"). The Expiration Date
will be at least 20 business days after the commencement of the Exchange Offer
in accordance with Rule 14e-1(a) under the Exchange Act. The Company expressly
reserves the right, at any time or from time to time, to extend the period of
time during which the Exchange Offer is open, and thereby delay acceptance for
exchange of any Old Notes, by giving oral or written notice to the Exchange
Agent and by timely public announcement no later than 9:00 a.m. New York City
time, on the next business day after the previously scheduled Expiration Date.
During any such extension, all Old Notes previously tendered will remain
subject to the Exchange Offer unless properly withdrawn.
    

     The Company expressly reserves the right to (i) terminate or amend the
Exchange Offer and not to accept for exchange any Old Notes not theretofore
accepted for exchange upon the occurrence of any of the events specified below
under "Certain Conditions to the Exchange Offer" which have not been waived by
the Company and (ii) amend the terms of the Exchange Offer in any manner which,
in its good faith judgment, is advantageous to the holders of the Old Notes,
whether before or after any tender of the Notes. If any such termination or
amendment occurs, the Company will notify the Exchange Agent and will either
issue a press release or give oral or written notice to the holders of the Old
Notes as promptly as practicable.

     For purposes of the Exchange Offer, a "business day" means any day other
than Saturday, Sunday or a date on which banking institutions are required or
authorized by New York State law to be closed, and consists of the time period
from 12:01 a.m. through 12:00 midnight, New York City time. Unless the Company
terminates the Exchange Offer prior to 5:00 p.m., New York City time, on the
Expiration Date, the Company will exchange the Exchange Notes for the Old Notes
on the Exchange Date.


PROCEDURES FOR TENDERING OLD NOTES

     The tender to the Company of Old Notes by a holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering holder and the Company upon the terms and
subject to the conditions set forth in this prospectus and in the accompanying
Letter of Transmittal.

     A holder of Old Notes may tender the same by (i) properly completing and
signing the Letter of Transmittal or a facsimile thereof (all references in
this prospectus to the Letter of Transmittal shall be deemed to include a
facsimile thereof) and delivering the same, together with the certificate or
certificates representing the Old Notes being tendered and any required
signature guarantees and any other documents required by the Letter of
Transmittal, to the Exchange Agent at its address set forth below on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below) or (ii) complying with the guaranteed delivery procedures
described below.

     The method of delivery of Old Notes, Letters of Transmittal and all other
required documents is at the election and risk of the holders. If such delivery
is by mail, it is recommended that registered mail properly insured, with
return receipt requested, be used. In all cases, sufficient time should be
allowed to insure timely delivery. No Old Notes or Letters of Transmittal
should be sent to the Company.

     If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the Exchange Notes to be issued in exchange therefor
are to be issued (and any untendered Old Notes are to be reissued) in the name
of the registered holder (which term, for the purposes described herein, shall
include any participant in The Depository Trust Company (also referred to as a
"book-entry transfer facility") whose name appears on a security listing as the
owner of Old Notes), the signature of such signer need not be guaranteed. In
any other case, the tendered Old Notes must be endorsed or accompanied by
written instruments of transfer in form satisfactory to the Company and duly
executed by the registered holder, and the signature on the endorsement or
instrument of


                                       89
<PAGE>

transfer must be guaranteed by a bank, broker, dealer, credit union, savings
association, clearing agency or other institution (each an "Eligible
Institution") that is a member of a recognized signature guarantee medallion
program within the meaning of Rule 17Ad-15 under the Exchange Act. If the
Exchange Notes and/or Old Notes not exchanged are to be delivered to an address
other than that of the registered holder appearing on the note register for the
Old Notes, the signature in the Letter of Transmittal must be guaranteed by an
Eligible Institution.

     The Exchange Agent will make a request within two business days after the
date of receipt of this prospectus to establish accounts with respect to the
Old Notes at the book-entry transfer facility for the purpose of facilitating
the Exchange Offer, and subject to the establishment thereof, any financial
institution that is a participant in the book-entry transfer facility's system
may make book-entry delivery of Old Notes by causing such book-entry transfer
facility to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with the book-entry transfer facility's
procedures for such transfer. Although delivery of Old Notes may be effected
through book-entry transfer into the Exchange Agent's account at the book-entry
transfer facility, an appropriate Letter of Transmittal with any required
signature guarantee and all other required documents must in each case be
transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures.

     If a holder desires to accept the Exchange Offer and time will not permit
a Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date or the procedure for book-entry transfer cannot be completed on
a timely basis, a tender may be effected if the Exchange Agent has received at
its address set forth below on or prior to the Expiration Date, a letter,
telegram or facsimile transmission (receipt confirmed by telephone and an
original delivered by guaranteed overnight courier) from an Eligible
Institution setting forth the name and address of the tendering holder, the
names in which the Old Notes are registered and, if possible, the certificate
numbers of the Old Notes to be tendered, and stating that the tender is being
made thereby and guaranteeing that within three business days after the
Expiration Date, the Old Notes in proper form for transfer (or a confirmation
of book-entry transfer of such Old Notes into the Exchange Agent's account at
the book-entry transfer facility), will be delivered by such Eligible
Institution together with a properly completed and duly executed Letter of
Transmittal (and any other required documents). Unless Old Notes being tendered
by the above-described method are deposited with the Exchange Agent within the
time period set forth above (accompanied or preceded by a properly completed
Letter of Transmittal and any other required documents), the Company may, at
its option, reject the tender. Copies of the notice of guaranteed delivery
("Notice of Guaranteed Delivery") which may be used by Eligible Institutions
for the purposes described in this paragraph are available from the Exchange
Agent.

     A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at the book-entry transfer
facility) is received by the Exchange Agent, or (ii) a Notice of Guaranteed
Delivery or letter, telegram or facsimile transmission to similar effect (as
provided above) from an Eligible Institution is received by the Exchange Agent.
Issuances of Exchange Notes in exchange for Old Notes tendered pursuant to a
Notice of Guaranteed Delivery or letter, telegram or facsimile transmission to
similar effect (as provided above) by an Eligible Institution will be made only
against deposit of the Letter of Transmittal (and any other required documents)
and the tendered Old Notes.

     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined
by the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or not to accept any
particular Old Notes which acceptance might, in the judgment of the Company or
its counsel, be unlawful. The Company also reserves the absolute right to waive
any defects or irregularities or conditions of the


                                       90
<PAGE>

Exchange Offer as to any particular Old Notes either before or after the
Expiration Date (including the right to waive the ineligibility of any holder
who seeks to tender Old Notes in the Exchange Offer). The interpretation of the
terms and conditions of the Exchange Offer (including the Letter of Transmittal
and the instructions thereto) by the Company shall be final and binding on all
parties. Unless waived, any defects or irregularities in connection with
tenders of Old Notes for exchange must be cured within such reasonable period
of time as the Company shall determine. Neither the Company, the Exchange Agent
nor any other person shall be under any duty to give notification of any defect
or irregularity with respect to any tender of Old Notes for exchange, nor shall
any of them incur any liability for failure to give such notification.

     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear on the Old
Notes.

     If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.

     By tendering, each holder will represent to the Company that, among other
things, the Exchange Notes acquired pursuant to the Exchange Offer are being
acquired in the ordinary course of business of the person receiving such
Exchange Notes, whether or not such person is the holder, that neither the
holder nor any such other person has an arrangement or understanding with any
person to participate in the distribution of such Exchange Notes and that
neither the holder nor any such other person is an "affiliate," as defined
under Rule 405 of the Securities Act, of the Company, or if it is an affiliate
it will comply with the registration and prospectus requirements of the
Securities Act to the extent applicable.

     Each broker-dealer that receives Exchange Notes for its own account in
exchange for Old Notes where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes. See "Plan of Distribution".


TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

     The Letter of Transmittal contains, among other things, the following
terms and conditions, which are part of the Exchange Offer.

     The party tendering Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The
Transferor represents and warrants that it has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire Exchange
Notes issuable upon the exchange of such tendered Notes, and that, when the
same are accepted for exchange, the Company will acquire good and unencumbered
title to the tendered Old Notes, free and clear of all liens, restrictions,
charges and encumbrances and not subject to any adverse claim. The Transferor
also warrants that it will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the exchange, assignment and transfer of tendered Old
Notes or transfer ownership of such Old Notes on the account books maintained
by a book-entry transfer facility. The Transferor further agrees that
acceptance of any tendered Old Notes by the Company and the issuance of
Exchange Notes in exchange therefor shall constitute performance in full by the
Company of certain of its obligations under the Registration Rights Agreement.
All authority conferred by the Transferor will survive the death or incapacity
of the Transferor and every obligation of the Transferor shall be binding upon
the heirs, legal representatives, successors, assigns, executors and
administrators of such Transferor.


                                       91
<PAGE>

     The Transferor certifies that it is not an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act and that it is
acquiring the Exchange Notes offered hereby in the ordinary course of such
Transferor's business and that such Transferor has no arrangement with any
person to participate in the distribution of such Exchange Notes.

     Each holder, other than a broker-dealer, must acknowledge that it is not
engaged in, and does not intend to engage in, a distribution of Exchange Notes.
Each Transferor which is a broker-dealer receiving Exchange Notes for its own
account must acknowledge that it will deliver a prospectus in connection with
any resale of such Exchange Notes. By so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. In connection with the
offering of the Old Notes, the Company agreed to file and maintain, subject to
certain limitations, a registration statement that would allow Lehman Brothers
Inc. to engage in market-making transactions with respect to the Notes. The
Company has agreed to bear registration expenses incurred under such agreement.
 


WITHDRAWAL RIGHTS

     Tenders of Old Notes may be withdrawn at any time prior to the Expiration
Date.

     For a withdrawal to be effective, a written notice of withdrawal sent by
telegram, facsimile transmission (receipt confirmed by telephone) or letter
must be received by the Exchange Agent at the address set forth herein prior to
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having tendered the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number
or numbers and principal amount of such Old Notes), (iii) specify the principal
amount of Notes to be withdrawn, (iv) include a statement that such holder is
withdrawing his election to have such Old Notes exchanged, (v) be signed by the
holder in the same manner as the original signature on the Letter of
Transmittal by which such Old Notes were tendered or as otherwise described
above (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee under the Indenture
register the transfer of such Old Notes into the name of the person withdrawing
the tender and (vi) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. The Exchange Agent will
return the properly withdrawn Old Notes promptly following receipt of notice of
withdrawal. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the book-entry transfer facility to be credited with the
withdrawn Old Notes or otherwise comply with the book-entry transfer facility
procedure. All questions as to the validity of notices of withdrawals,
including time of receipt, will be determined by the Company and such
determination will be final and binding on all parties.

     Any Old Notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the Exchange Offer. Any Old Notes which
have been tendered for exchange but which are not exchanged for any reason will
be returned to the holder thereof without cost to such holder (or, in the case
of Old Notes tendered by book-entry transfer into the Exchange Agent's account
at the book-entry transfer facility pursuant to the book-entry transfer
procedures described above, such Old Notes will be credited to an account with
such book-entry transfer facility specified by the holder) as soon as
practicable after withdrawal, rejection of tender or termination of the
Exchange Offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures described under "Procedures for Tendering Old Notes" above at
any time on or prior to the Expiration Date.


ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

     Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Company will accept, promptly on the Exchange Date, all Old Notes
properly tendered and will issue the Exchange Notes promptly after such
acceptance. See "Certain Conditions to the Exchange Offer" below. For purposes
of the Exchange Offer, the Company shall be deemed to have accepted properly
tendered Old Notes for exchange when, as and if the Company has given oral or
written notice thereof to the Exchange Agent.


                                       92
<PAGE>

     For each Old Note accepted for exchange, the holder of such Old Note will
receive an Exchange Note having a principal amount equal to that of the
surrendered Old Note.

     In all cases, issuance of Exchange Notes for Old Notes that are accepted
for exchange pursuant to the Exchange Offer will be made only after timely
receipt by the Exchange Agent of certificates for such Old Notes or a timely
book-entry confirmation of such Old Notes into the Exchange Agent's account at
the book-entry transfer facility, a properly completed and duly executed Letter
of Transmittal and all other required documents. If any tendered Old Notes are
not accepted for any reason set forth in the terms and conditions of the
Exchange Offer or if Old Notes are submitted for a greater principal amount
than the holder desires to exchange, such unaccepted or non-exchanged Old Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Old Notes tendered by book-entry transfer into the Exchange Agent's
account at the book-entry transfer facility pursuant to the book-entry transfer
procedures described above, such non-exchanged Old Notes will be credited to an
account maintained with such book-entry transfer facility) as promptly as
practicable after the expiration of the Exchange Offer.

CERTAIN CONDITIONS TO THE EXCHANGE OFFER

     Notwithstanding any other provision of the Exchange Offer, or any
extension of the Exchange Offer, the Company shall not be required to accept
for exchange, or to issue Exchange Notes in exchange for, any Old Notes and may
terminate or amend the Exchange Offer (by oral or written notice to the
Exchange Agent or by a timely press release) if at any time before the
acceptance of such Old Notes for exchange or the exchange of the Exchange Notes
for such Old Notes, any of the following conditions exist:

     (a) any action or proceeding is instituted or threatened in any court or
   by or before any governmental agency or regulatory authority or any
   injunction, order or decree is issued with respect to the Exchange Offer
   which, in the sole judgment of the Company, might materially impair the
   ability of the Company to proceed with the Exchange Offer or have a
   material adverse effect on the contemplated benefits of the Exchange Offer
   to the Company; or

     (b) any change (or any development involving a prospective change) shall
   have occurred or be threatened in the business, properties, assets,
   liabilities, financial condition, operations, results of operations or
   prospects of the Company that is or may be adverse to the Company, or the
   Company shall have become aware of facts that have or may have adverse
   significance with respect to the value of the Old Notes or the Exchange
   Notes or that may materially impair the contemplated benefits of the
   Exchange Offer to the Company; or

     (c) any law, rule or regulation or applicable interpretations of the
   staff of the Commission is issued or promulgated which, in the good faith
   determination of the Company, do not permit the Company to effect the
   Exchange Offer; or

     (d) any governmental approval has not been obtained, which approval the
   Company, in its sole discretion, deems necessary for the consummation of
   the Exchange Offer; or

     (e) there shall have been proposed, adopted or enacted any law, statute,
   rule or regulation (or an amendment to any existing law statute, rule or
   regulation) which, in the sole judgment of the Company, might materially
   impair the ability of the Company to proceed with the Exchange Offer or
   have a material adverse effect on the contemplated benefits of the Exchange
   Offer to the Company; or

     (f) there shall occur a change in the current interpretation by the staff
   of the Commission which permits the Exchange Notes issued pursuant to the
   Exchange Offer in exchange for Old Notes to be offered for resale, resold
   and otherwise transferred by holders thereof (other than any such holder
   that is an "affiliate" of the Company within the meaning of Rule 405 under
   the Securities Act) without compliance with the registration and prospectus
   delivery provisions of the Securities Act provided that such Exchange Notes
   are acquired in the ordinary course of such holders' business and such
   holders have no arrangement with any person to participate in the
   distribution of such Exchange Notes; or


                                       93
<PAGE>

     (g) there shall have occurred (i) any general suspension of, shortening
   of hours for, or limitation on prices for, trading in securities on any
   national securities exchange or in the over-the-counter market (whether or
   not mandatory), (ii) any limitation by any governmental agency or authority
   which may adversely affect the ability of the Company to complete the
   transactions contemplated by the Exchange Offer, (iii) a declaration of a
   banking moratorium or any suspension of payments in respect of banks by
   Federal or state authorities in the United States (whether or not
   mandatory), (iv) a commencement of a war, armed hostilities or other
   international or national crisis directly or indirectly involving the
   United States, (v) any limitation (whether or not mandatory) by any
   governmental authority on, or other event having a reasonable likelihood of
   affecting, the extension of credit by banks or other leading institutions
   in the United States, or (vi) in the case of any of the foregoing existing
   at the time of the commencement of the Exchange Offer, a material
   acceleration or worsening thereof.


     The Company expressly reserves the right to terminate the Exchange Offer
and not accept for exchange any Old Notes upon the occurrence of any of the
foregoing conditions (which represent all of the material conditions to the
acceptance by the Company of properly tendered Old Notes). In addition, the
Company may amend the Exchange Offer at any time prior to the Expiration Date
if any of the conditions set forth above occur. Moreover, regardless of whether
any of such conditions has occurred, the Company may amend the Exchange Offer
in any manner which, in its good faith judgment, is advantageous to holders of
the Old Notes.


     The foregoing conditions are for the sole benefit of the Company and may
be asserted by the Company regardless of the circumstances giving rise to any
such condition or may be waived by the Company in whole or in part at any time
and from time to time in its sole discretion. The failure by the Company at any
time to exercise any of the foregoing rights shall not be deemed a waiver of
any such right and each such right shall be deemed an ongoing right which may
be asserted at any time and from time to time.


     If the Company waives or amends the foregoing conditions, it will, if
required by law, extend the Exchange Offer for a minimum of five business days
from the date that the Company first gives notice, by public announcement or
otherwise, of such waiver or amendment, if the Exchange Offer would otherwise
expire within such five business-day period. Any determination by the Company
concerning the events described above will be final and binding upon all
parties.


     In addition, the Company will not accept for exchange any Old Notes
tendered, and no Exchange Notes will be issued in exchange for any such Old
Notes, if at such time any stop order shall be threatened or in effect with
respect to the Registration Statement of which this Prospectus constitutes a
part or the qualification of the Indenture under the Trust Indenture Act of
1939, as amended. In any such event the Company is required to use every
reasonable effort to obtain the withdrawal of any stop order at the earliest
possible time.


     The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered for exchange.

     DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ON THE LETTER OF
TRANSMITTAL, OR TRANSMISSIONS OF INSTRUCTIONS VIA A FACSIMILE OR TELEX NUMBER
OTHER THAN THE ONES SET FORTH ON THE LETTER OF TRANSMITTAL, WILL NOT CONSTITUTE
A VALID DELIVERY.

SOLICITATION OF TENDERS; FEES AND EXPENSES

     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection therewith.
The Company will also pay brokerage houses and other custodians, nominees and
fiduciaries the reasonable out-of-pocket expenses incurred by them in
forwarding copies of this and other related documents to the beneficial owners
of the Old Notes and in handling or forwarding tenders for their customers.

     The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
approximately $250,000, which includes fees and expenses of the Exchange Agent,
Trustee, registration fees, accounting, legal, printing and related fees and
expenses.

     No person has been authorized to give any information or to make any
representations in connection with the Exchange Offer other than those
contained in this prospectus. If given or made, such information or
representations should not be relied upon as having been authorized by the
Company. Neither the delivery of this prospectus nor any exchange made
hereunder shall, under any circumstances, create any implication that there has
been no change in the affairs of the Company since the respective dates as of
which information is given herein. The Exchange Offer is not being made to (nor
will tenders be accepted from or on behalf of) holders of Old Notes in any
jurisdiction in which the making of the Exchange Offer or the acceptance
thereof would not be in compliance with the laws of such jurisdiction. However,
the Company may, at its discretion, take such action as it may deem necessary
to make the Exchange Offer in any such jurisdiction and extend the Exchange
Offer to holders of Old Notes in such jurisdiction. In any jurisdiction in
which the securities laws or blue sky laws of which require the Exchange Offer
to be made by a licensed broker or dealer, the Exchange Offer is being made on
behalf of the Company by one or more registered brokers or dealers which are
licensed under the laws of such jurisdiction.

TRANSFER TAXES

     The Company will pay all transfer taxes, if any, applicable to the
exchange of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes or Old Notes for


                                       95
<PAGE>

principal amounts not tendered or accepted for exchange are to be delivered to,
or are to be issued in the name of, any person other than the registered holder
of the Old Notes tendered, or if tendered Old Notes are registered in the name
of any person other than the person signing the Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or any other persons) will be payable
by the tendering holder. If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with the Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering holder.


ACCOUNTING TREATMENT

     The Exchange Notes will be recorded at the carrying value of the Old Notes
as reflected in the Company's accounting records on the date of the exchange.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company upon the exchange of Exchange Notes for Old Notes. Expenses incurred in
connection with the issuance of the Exchange Notes will be amortized over the
term of the Exchange Notes.


CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders of Old Notes who do not exchange their Old Notes for Exchange
Notes pursuant to the Exchange Offer will continue to be subject to the
restrictions on transfer of such Old Notes as set forth in the legend thereon.
Old Notes not exchanged pursuant to the Exchange Offer will continue to remain
outstanding in accordance with their terms. In general, the Old Notes may not
be offered or sold unless registered under the Securities Act, except pursuant
to an exemption from, or in a transaction not subject to, the Securities Act
and applicable state securities laws. The Company does not currently anticipate
that it will register the Old Notes under the Securities Act.

     Participation in the Exchange Offer is voluntary, and holders of Old Notes
should carefully consider whether to participate. Holders of Old Notes are
urged to consult their financial and tax advisors in making their own decision
on what action to take.

     As a result of the making of, and upon acceptance for exchange of all
validly tendered Old Notes pursuant to the terms of, this Exchange Offer, the
Company will have fulfilled a covenant contained in the Registration Rights
Agreement. Holders of Old Notes who do not tender their Old Notes in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights and limitations applicable thereto under the Indenture, except for
any such rights under the Registration Rights Agreement that by their terms
terminate or cease to have further effectiveness as a result of the making of
this Exchange Offer. All untendered Old Notes will continue to be subject to
the restrictions on transfer set forth in the Indenture. To the extent that Old
Notes are tendered and accepted in the Exchange Offer, the trading market for
untendered Old Notes could be adversely affected.

     The Company may in the future seek to acquire, subject to the terms of the
Indenture, untendered Old Notes in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise. The Company has
no present plan to acquire any Old Notes which are not tendered in the Exchange
Offer.


RESALE OF EXCHANGE NOTES

     The Company is making the Exchange Offer in reliance on the position of
the staff of the Commission as set forth in certain interpretive letters
addressed to third parties in other transactions. However, the Company has not
sought its own interpretive letter and there can be no assurance that the Staff
would make a similar determination with respect to the Exchange Offer as it has
in such interpretive letters to third parties. Based on these interpretations
by the staff, the Company believes that the Exchange Notes issued pursuant to
the Exchange Offer in exchange for Old Notes may be offered for resale, resold
and otherwise transferred by a Holder (other than any Holder who is a
broker-dealer or an "affiliate" of the Company within the meaning of Rule 405
of the Securities Act)


                                       96
<PAGE>

without further compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that such Exchange Notes are
acquired in the ordinary course of such Holder's business and that such Holder
is not participating, and has no arrangement or understanding with any person
to participate, in a distribution (within the meaning of the Securities Act) of
such Exchange Notes. However, any holder who is an "affiliate" of the Company
or who has an arrangement or understanding with respect to the distribution of
the Exchange Notes to be acquired pursuant to the Exchange Offer, or any
broker-dealer who purchased Old Notes from the Company to resell pursuant to
Rule 144A or any other available exemption under the Securities Act (i) could
not rely on the applicable interpretations of the staff and (ii) must comply
with the registration and prospectus delivery requirements of the Securities
Act. A broker-dealer who holds Old Notes that were acquired for its own account
as a result of market-making or other trading activities may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of Exchange Notes. Each such broker-dealer that
receives Exchange Notes for its own account in exchange for Old Notes, where
such Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge in the Letter of
Transmittal that it will deliver a prospectus in connection with any resale of
such Exchange Notes. See "Plan of Distribution".


     In addition, to comply with the securities laws of certain jurisdictions,
if applicable, the Exchange Notes may not be offered or sold unless they have
been registered or qualified for sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company
has agreed, pursuant to the Registration Rights Agreement and subject to
certain specified limitations therein, to register or qualify the Exchange
Notes for offer or sale under the securities or blue sky laws of such
jurisdictions as any holder of the Exchange Notes reasonably requests. Such
registration or qualification may require the imposition of restrictions or
conditions (including suitability requirements for offerees or purchasers) in
connection with the offer or sale of any Exchange Notes.

                       DESCRIPTION OF THE EXCHANGE NOTES


GENERAL

     The Old Notes were issued and the Exchange Notes offered hereby will be
issued under an indenture dated as of December 11, 1998 (the "Indenture") among
the Company, as issuer, the Guarantors named therein and The Bank of New York,
as trustee (the "Trustee"). The terms of the Exchange Notes include those
stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Exchange Notes are subject to all such terms, and holders of the Exchange Notes
are referred to the Indenture and the Trust Indenture Act for a statement
thereof. The following summary of the material provisions of the Indenture
describes the material terms of the Indenture but does not purport to be
complete and is subject to, and qualified in its entirety by reference to, the
provisions of the Indenture, including the definitions of certain terms
contained therein and those terms made part of the Indenture by reference to
the Trust Indenture Act. For definitions of certain capitalized terms used in
the following summary, see "-- Certain Definitions". The Indenture is an
exhibit to the Registration Statement of which this prospectus is a part.

     For purposes of this summary, the term "Company" refers only to L-3
Communications Corporation and not to any of its Subsidiaries.

     On December 11, 1998, the Company issued $200.0 million aggregate
principal amount of Old Notes under the Indenture. The terms of the Exchange
Notes are identical in all material respects to the Old Notes, except for
certain transfer restrictions and registration and other rights relating to the
exchange of the Old Notes for Exchange Notes. The Trustee will authenticate and
deliver Exchange Notes for original issue only in exchange for a like principal
amount of Old Notes. Any Old Notes that remain outstanding after the
consummation of the Exchange Offer, together with the Exchange Notes, will be
treated as a single class of securities under the Indenture. Accordingly, all
references herein to specified percentages in aggregate principal amount of the
outstanding Exchange Notes shall be deemed to mean, at any time after the
Exchange Offer is consummated, such percentage in aggregate principal amount of
the Old Notes and Exchange Notes then outstanding.

     The Exchange Notes will be general unsecured obligations of the Company
and will rank pari passu in right of payment with the 1997 Notes and the May
1998 Notes and are subordinated in right of payment to all current and future
Senior Debt. At September 30, 1998, on a pro forma basis giving effect to the
Old Notes Offering, the Company would not have had any Senior Debt outstanding
(excluding letters of credit). The Indenture permits the incurrence of
additional Senior Debt in the future. See "-- Certain Covenants -- Incurrence
of Indebtedness and Issuance of Preferred Stock".

     The Indenture provides that the Company's payment obligations under the
Notes are jointly and severally guaranteed (the "Subsidiary Guarantees") by all
of the Company's present and future Restricted Subsidiaries, other than Foreign
Subsidiaries (collectively, the "Guarantors"). The Subsidiary Guarantee of each
Guarantor will be subordinated to the prior payment in full of all Senior Debt
of such Guarantor, which would include the guarantees of amounts borrowed under
the Senior Credit Facilities.

     As of the date of the Indenture, not all of the Company's subsidiaries
were "Restricted Subsidiaries." Cardiovascular Computer Systems, Ltd., L-3
Secure Information Technology and L-3 Network Security are currently
Unrestricted Subsidiaries. In addition, under the circumstances described below
under the subheading "Certain Covenants -- Restricted Payments", the Company is
permitted to designate certain of the Company's subsidiaries as "Unrestricted
Subsidiaries". Unrestricted Subsidiaries are not subject to many of the
restrictive covenants in the Indenture. Unrestricted Subsidiaries do not
guarantee these Notes.


PRINCIPAL, MATURITY AND INTEREST

     The Exchange Notes will be limited in aggregate principal amount to $200.0
million and will mature on August 1, 2008. Interest on the Exchange Notes will
accrue at the rate of 8% per annum


                                       98
<PAGE>

and will be payable semi-annually in arrears on February 1 and August 1,
commencing on February 1, 1999, to Holders of record on the immediately
preceding January 15 and July 15. The Company may issue Additional Notes (the
"Additional Notes") from time to time after the offering of the Exchange Notes.
Any offering of Additional Notes is subject to the covenant described below
under the caption "Certain Covenants -- Incurrence of Indebtedness and Issuance
of Preferred Stock". The Notes and any Additional Notes subsequently issued
under the Indenture would be treated as a single class for all purposes under
the Indenture, including, without limitation, waivers, amendments, redemptions
and offers to purchase. Interest on the Exchange Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from the date of original issuance. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. Principal, premium
and Liquidated Damages, if any, and interest on the Exchange Notes will be
payable at the office or agency of the Company maintained for such purpose
within the City and State of New York or, at the option of the Company, payment
of interest and Liquidated Damages, if any, may be made by check mailed to the
Holders of the Exchange Notes at their respective addresses set forth in the
register of Holders of Exchange Notes; provided that all payments of principal,
premium, interest and Liquidated Damages with respect to Exchange Notes the
Holders of which have given wire transfer instructions to the Company will be
required to be made by wire transfer of immediately available funds to the
accounts specified by the Holders thereof if such Holders shall be registered
Holders of at least $250,000 in principal amount of Exchange Notes. Until
otherwise designated by the Company, the Company's office or agency in New York
will be the office of the Trustee maintained for such purpose. The Exchange
Notes will be issued in denominations of $1,000 and integral multiples thereof.
 


OPTIONAL REDEMPTION

     The Exchange Notes will not be redeemable at the Company's option prior to
August 1, 2003. Thereafter, the Exchange Notes will be subject to redemption at
any time at the option of the Company, in whole or in part, upon not less than
30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Liquidated Damages, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on August 1 of the years
indicated below:




<TABLE>
<CAPTION>
YEAR                                       PERCENTAGE
- ---------------------------------------   -----------
<S>                                       <C>
  2003 ................................   104.000%
  2004 ................................   102.667%
  2005 ................................   101.333%
  2006 and thereafter .................   100.000%
</TABLE>

     Notwithstanding the foregoing, during the first 36 months after the Issue
Date, the Company may on any one or more occasions redeem up to an aggregate of
35% of the Exchange Notes originally issued at a redemption price of 108.000%
of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, to the redemption date, with the net cash proceeds
of one or more Equity Offerings by the Company or the net cash proceeds of one
or more Equity Offerings by Holdings that are contributed to the Company as
common equity capital; provided that at least 65% of the Exchange Notes
originally issued remain outstanding immediately after the occurrence of each
such redemption; and provided, further, that any such redemption must occur
within 120 days of the date of the closing of such Equity Offering.


SUBORDINATION

     The payment of principal of, premium and Liquidated Damages, if any, and
interest on the Exchange Notes will be subordinated in right of payment, as set
forth in the Indenture, to the prior payment in full of all Senior Debt,
whether outstanding on the Issue Date or thereafter incurred.

     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the


                                       99
<PAGE>

Company's assets and liabilities, the holders of Senior Debt will be entitled
to receive payment in full in cash of all Obligations due in respect of such
Senior Debt (including interest after the commencement of any such proceeding
at the rate specified in the applicable Senior Debt, whether or not an
allowable claim in any such proceeding) before the Holders of Exchange Notes
will be entitled to receive any payment with respect to the Exchange Notes, and
until all Obligations with respect to Senior Debt are paid in full, any
distribution to which the Holders of Exchange Notes would be entitled shall be
made to the holders of Senior Debt (except, in each case, that Holders of
Exchange Notes may receive Permitted Junior Securities and payments made from
the trust described under "-- Legal Defeasance and Covenant Defeasance").

     The Company also may not make any payment upon or in respect of the
Exchange Notes (except from the trust described under "-- Legal Defeasance and
Covenant Defeasance") if:

     (i) a default in the payment of the principal of, premium, if any, or
   interest on Designated Senior Debt occurs and is continuing; or

     (ii) any other default occurs and is continuing with respect to
   Designated Senior Debt that permits holders of the Designated Senior Debt
   as to which such default relates to accelerate its maturity (or that would
   permit such holders to accelerate with the giving of notice or the passage
   of time or both) and the Trustee receives a notice of such default (a
   "Payment Blockage Notice") from the Company or the holders of any
   Designated Senior Debt.

     Payments on the Exchange Notes may and shall be resumed:

         (A) in the case of a payment default, upon the date on which such
       default is cured or waived; and

         (B) in case of a nonpayment default, the earlier of the date on which
       such nonpayment default is cured or waived or 179 days after the date on
       which the applicable Payment Blockage Notice is received, unless the
       maturity of any Designated Senior Debt has been accelerated.

     No new period of payment blockage may be commenced unless and until:

     (i) 360 days have elapsed since the effectiveness of the immediately
   prior Payment Blockage Notice; and

     (ii) all scheduled payments of principal, premium and Liquidated Damages,
   if any, and interest on the Exchange Notes that have come due have been
   paid in full in cash.

     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made,
the basis for a subsequent Payment Blockage Notice unless such default shall
have been waived for a period of not less than 90 days.

     The Indenture further requires that the Company promptly notify holders of
Senior Debt if payment of the Exchange Notes is accelerated because of an Event
of Default.

     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency, Holders of Exchange Notes may recover less
ratably than creditors of the Company who are holders of Senior Debt. On a pro
forma basis, after giving effect to the Old Notes Offering, there would not
have been any Senior Debt outstanding at September 30, 1998.


SELECTION AND NOTICE

     If less than all of the Exchange Notes are to be redeemed at any time,
selection of Exchange Notes for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Exchange Notes are listed, or, if the Exchange Notes are
not so listed, on a pro rata basis, by lot or by such method as the Trustee
shall deem fair and appropriate; provided that no Exchange Notes of $1,000 or
less shall be redeemed in part. Notices of redemption shall be mailed by first
class mail at least 30 but not more than 60 days before the redemption date to
each Holder of Exchange Notes to be redeemed at its registered


                                      100
<PAGE>

address. Notices of redemption may not be conditional. If any Note is to be
redeemed in part only, the notice of redemption that relates to such Note shall
state the portion of the principal amount thereof to be redeemed. A new Note in
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Note. Exchange
Notes called for redemption become due on the date fixed for redemption. On and
after the redemption date, interest ceases to accrue on Exchange Notes or
portions of them called for redemption.


MANDATORY REDEMPTION

     Except as set forth below under "-- Repurchase at the Option of Holders",
the Company is not required to make mandatory redemption or sinking fund
payments with respect to the Exchange Notes.


REPURCHASE AT THE OPTION OF HOLDERS

 CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, each Holder of Exchange Notes
will have the right to require the Company to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of such Holder's Exchange Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase (the "Change of Control Payment"). Within ten days following any
Change of Control, the Company will mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Exchange Notes on the date specified in such notice, which date
shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed (the "Change of Control Payment Date"), pursuant to the
procedures required by the Indenture and described in such notice. The Company
will comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Exchange
Notes as a result of a Change of Control.

     On the Change of Control Payment Date, the Company will, to the extent
lawful:

     (i) accept for payment all Exchange Notes or portions thereof properly
   tendered pursuant to the Change of Control Offer;

     (ii) deposit with the Paying Agent an amount equal to the Change of
   Control Payment in respect of all Exchange Notes or portions thereof so
   tendered; and

     (iii) deliver or cause to be delivered to the Trustee the Exchange Notes
   so accepted together with an Officers' Certificate stating the aggregate
   principal amount of Exchange Notes or portions thereof being purchased by
   the Company.

     The Paying Agent will promptly mail to each Holder of Exchange Notes so
tendered the Change of Control Payment for such Exchange Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Exchange Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each such new Exchange
Note will be in a principal amount of $1,000 or an integral multiple thereof.

     The Indenture provides that, prior to mailing a Change of Control Offer,
but in any event within 90 days following a Change of Control, the Company will
either repay all outstanding Senior Debt or offer to repay all Senior Debt and
terminate all commitments thereunder of each lender who has accepted such offer
or obtain the requisite consents, if any, under all agreements governing
outstanding Senior Debt to permit the repurchase of Exchange Notes required by
this covenant. The Company will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

     The Change of Control provisions described above will be applicable
whether or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of


                                      101
<PAGE>

Control, the Indenture does not contain provisions that permit the Holders of
the Exchange Notes to require that the Company repurchase or redeem the
Exchange Notes in the event of a takeover, recapitalization or similar
transaction.

     The Senior Credit Facilities will prohibit the Company from purchasing any
Exchange Notes, and also provides that certain change of control events with
respect to the Company would constitute a default thereunder. Any future credit
agreements or other agreements relating to Senior Debt to which the Company
becomes a party may contain similar restrictions and provisions. In the event a
Change of Control occurs at a time when the Company is prohibited from
purchasing Exchange Notes, the Company could seek the consent of its lenders to
the purchase of Exchange Notes or could attempt to refinance the borrowings
that contain such prohibition. If the Company does not obtain such a consent or
repay such borrowings, the Company will remain prohibited from purchasing
Exchange Notes. In such case, the Company's failure to purchase tendered
Exchange Notes would constitute an Event of Default under the Indenture, the
May 1998 Indenture and 1997 Indenture which would, in turn, constitute a
default under the Senior Credit Facilities. In such circumstances, the
subordination provisions in the Indenture would likely restrict payments to the
Holders of Exchange Notes. See "Risk Factors -- We are Required to Take Certain
Actions Upon a Change of Control". Finally, the Company's ability to pay cash
to the holders of Exchange Notes upon a purchase may be limited by the
Company's then-existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
purchases. Even if sufficient funds were otherwise available, the terms of the
Senior Credit Facilities will prohibit, subject to certain exceptions, the
Company's prepayment of Exchange Notes prior to their scheduled maturity.
Consequently, if the Company is not able to prepay indebtedness outstanding
under the Senior Credit Facilities and any other Senior Debt containing similar
restrictions or obtain requisite consents, the Company will be unable to
fulfill its repurchase obligations if holders of Exchange Notes exercise their
purchase rights following a Change of Control, thereby resulting in a default
under the Indenture, the May 1998 Indenture and 1997 Indenture. Furthermore,
the Change of Control provisions of the Indenture, the May 1998 Indenture and
1997 Indenture may in certain circumstances make more difficult or discourage a
takeover of the Company.

     The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set
forth in the Indenture applicable to a Change of Control Offer made by the
Company and purchases all Exchange Notes validly tendered and not withdrawn
under such Change of Control Offer.

     "Change of Control" means the occurrence of any of the following:

     (i) the sale, lease, transfer, conveyance or other disposition (other
   than by way of merger or consolidation), in one or a series of related
   transactions, of all or substantially all of the assets of the Company and
   its Restricted Subsidiaries taken as a whole to any "person" (as such term
   is used in Section 13(d)(3) of the Exchange Act) other than the Principals
   or their Related Parties (as defined below);

   
     (ii) the adoption of a plan relating to the liquidation or dissolution
   of the Company;
    

     (iii) the consummation of any transaction (including, without limitation,
   any merger or consolidation) the result of which is that any "person" (as
   defined above), other than the Principals and their Related Parties,
   becomes the "beneficial owner" (as such term is defined in Rule 13d-3 and
   Rule 13d-5 under the Exchange Act), directly or indirectly, of more than
   50% of the Voting Stock of the Company (measured by voting power rather
   than number of shares); or

     (iv) the first day on which a majority of the members of the Board of
   Directors of the Company are not Continuing Directors.

     "Continuing Directors" means, as of any date of determination, any member
of the Board of Directors of the Company who:


                                      102
<PAGE>

     (i) was a member of such Board of Directors on May 22, 1998; or

     (ii) was nominated for election or elected to such Board of Directors
   with the approval of a majority of the Continuing Directors who were
   members of such Board at the time of such nomination or election.

     "Principals" means any Lehman Investor, Lockheed Martin Corporation, Frank
C. Lanza and Robert V. LaPenta.

     "Related Party" with respect to any Principal means:

     (i) any controlling stockholder, 50% (or more) owned Subsidiary, or
   spouse or immediate family member (in the case of an individual) of such
   Principal; or

     (ii) any trust, corporation, partnership or other entity, the
   beneficiaries, stockholders, partners, owners or Persons beneficially
   holding a more than 50% controlling interest of which consist of such
   Principal and/or such other Persons referred to in the immediately
   preceding clause (i).

     "Voting Stock" of any Person as of any date means the Capital Stock of
such Person that is at the time entitled to vote in the election of the Board
of Directors of such Person.

     With respect to the disposition of assets, the phrase "all or
substantially all" as used in the Indenture varies according to the facts and
circumstances of the subject transaction and is subject to judicial
interpretation. Accordingly, in certain circumstances there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of the Company, and
therefore it may be unclear as to whether a Change of Control has occurred and
whether the holders have the right to require the Company to purchase the
Notes. In the event that the Company were to determine that a Change of Control
did not occur because not "all or substantially all" of the assets of the
Company and its Restricted Subsidiaries had been sold and the holders of the
Notes disagreed with such determination, the holders and/or the Trustee would
need to seek a judicial determination of the issue.


 ASSET SALES

     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, consummate an Asset Sale unless:

     (i) the Company (or the Restricted Subsidiary, as the case may be)
   receives consideration at the time of such Asset Sale at least equal to the
   fair market value (evidenced by an Officers' Certificate delivered to the
   Trustee which will include a resolution of the Board of Directors with
   respect to such fair market value in the event such Asset Sale involves
   aggregate consideration in excess of $5.0 million) of the assets or Equity
   Interests issued or sold or otherwise disposed of; and

     (ii) at least 80% of the consideration therefor received by the Company
   or such Restricted Subsidiary, as the case may be, consists of cash, Cash
   Equivalents and/or Marketable Securities;

provided, however, that:

         (A) the amount of any Senior Debt of the Company or such Restricted
       Subsidiary that is assumed by the transferee in any such transaction;
       and

         (B) any consideration received by the Company or such Restricted
       Subsidiary, as the case may be, that consists of (1) all or
       substantially all of the assets of one or more Similar Businesses, (2)
       other long-term assets that are used or useful in one or more Similar
       Businesses and (3) Permitted Securities shall be deemed to be cash for
       purposes of this provision.

     Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option:


                                      103
<PAGE>

     (i) to repay Indebtedness under a Credit Facility; or

     (ii) to the acquisition of Permitted Securities, all or substantially all
   of the assets of one or more Similar Businesses, or the making of a capital
   expenditure or the acquisition of other long-term assets in a Similar
   Business.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce Indebtedness under a Credit Facility or otherwise invest
such Net Proceeds in any manner that is not prohibited by the Indenture. Any
Net Proceeds from Asset Sales that are not applied or invested as provided in
the first sentence of this paragraph will be deemed to constitute "Excess
Proceeds". When the aggregate amount of Excess Proceeds exceeds $10.0 million,
the 1997 Indenture provides that the Company will be required to make an offer
to all holders of 1997 Notes (an "Asset Sale Offer") to purchase the maximum
principal amount of 1997 Notes that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal
amount thereof plus accrued and unpaid interest and Liquidated Damages, if any,
to the date of purchase, in accordance with the procedures set forth in the
1997 Indenture. To the extent that the aggregate amount of 1997 Notes tendered
pursuant to an Asset Sale Offer is less than the remaining Excess Proceeds
("Remaining Excess Proceeds") and the sum of:

         (A) such amount of Remaining Excess Proceeds; and

         (B) the Remaining Excess Proceeds from any subsequent Asset Sale
       Offers exceeds $3.0 million,

the Company will be required to make an offer to all Holders of Exchange Notes
and any other Indebtedness that ranks pari passu with the Exchange Notes
(including the May 1998 Notes) that, by its terms, requires the Company to
offer to repurchase such Indebtedness with such Remaining Excess Proceeds (a
"Secondary Asset Sale Offer") to purchase the maximum principal amount of Notes
and pari passu Indebtedness that may be purchased out of such Remaining Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal
amount thereof plus accrued and unpaid interest thereon, if any, to the date of
purchase, in accordance with the procedures set forth in the Indenture. To the
extent that the aggregate amount of Exchange Notes or pari passu Indebtedness
tendered pursuant to a Secondary Asset Sale Offer is less than the Remaining
Excess Proceeds, the Company may use any Remaining Excess Proceeds for general
corporate purposes. If the aggregate principal amount of Exchange Notes or pari
passu Indebtedness surrendered by Holders thereof exceeds the amount of
Remaining Excess Proceeds in a Secondary Asset Sale Offer, the Company shall
repurchase such Indebtedness on a pro rata basis and the Trustee shall select
the Exchange Notes to be purchased on a pro rata basis. Upon completion of such
offer to purchase, the amount of Excess Proceeds shall be reset at zero.

     The Senior Credit Facilities will substantially limit the Company's
ability to purchase subordinated Indebtedness, including the Exchange Notes.
Any future credit agreements relating to Senior Debt may contain similar
restrictions. See "Description of Certain Indebtedness -- Senior Credit
Facilities".


CERTAIN COVENANTS


 RESTRICTED PAYMENTS

     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly:

     (i) declare or pay any dividend or make any other payment or distribution
   on account of the Company's or any of its Restricted Subsidiaries' Equity
   Interests (including, without limitation, any payment in connection with
   any merger or consolidation involving the Company) or to the direct or
   indirect holders of the Company's or any of its Restricted Subsidiaries'
   Equity Interests in their capacity as such (other than (A) dividends or
   distributions payable in Equity Interests (other than Disqualified Stock)
   of the Company or (B) dividends or distributions by a Restricted


                                      104
<PAGE>

   Subsidiary so long as, in the case of any dividend or distribution payable
   on or in respect of any class or series of securities issued by a
   Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, the
   Company or a Restricted Subsidiary receives at least its pro rata share of
   such dividend or distribution in accordance with its Equity Interests in
   such class or series of securities);

     (ii) purchase, redeem or otherwise acquire or retire for value (including
   without limitation, in connection with any merger or consolidation
   involving the Company) any Equity Interests of the Company or any direct or
   indirect parent of the Company;

     (iii) make any payment on or with respect to, or purchase, redeem,
   defease or otherwise acquire or retire for value any Indebtedness that is
   subordinated to the Exchange Notes except a payment of interest or
   principal at Stated Maturity; or

     (iv) make any Restricted Investment (all such payments and other actions
   set forth in clauses (i) through (iv) above being collectively referred to
   as "Restricted Payments"),

   unless, at the time of and after giving effect to such Restricted Payment:

         (a) no Default or Event of Default shall have occurred and be
       continuing or would occur as a consequence thereof; and

         (b) the Company would, at the time of such Restricted Payment and
       after giving pro forma effect thereto as if such Restricted Payment had
       been made at the beginning of the applicable four-quarter period, have
       been permitted to incur at least $1.00 of additional Indebtedness
       pursuant to the Fixed Charge Coverage Ratio test set forth in the first
       paragraph of the covenant described below under caption "Incurrence of
       Indebtedness and Issuance of Preferred Stock"; and

         (c) such Restricted Payment, together with the aggregate amount of all
       other Restricted Payments made by the Company and its Restricted
       Subsidiaries since April 30, 1997 (excluding Restricted Payments
       permitted by clauses (ii) through (vii) of the next succeeding paragraph
       or of the kind contemplated by such clauses that were made prior to the
       date of the Indenture), is less than the sum of:

            (i) 50% of the Consolidated Net Income of the Company for the
          period (taken as one accounting period) from July 1, 1997 to the end
          of the Company's most recently ended fiscal quarter for which
          internal financial statements are available at the time of such
          Restricted Payment (or, if such Consolidated Net Income for such
          period is a deficit, less 100% of such deficit); plus

            (ii) 100% of the aggregate net cash proceeds received by the
          Company since April 30, 1997 from a contribution to its common equity
          capital or the issue or sale of Equity Interests of the Company
          (other than Disqualified Stock) or of Disqualified Stock or debt
          securities of the Company that have been converted into such Equity
          Interests (other than Equity Interests (or Disqualified Stock or
          convertible debt securities) sold to a Subsidiary of the Company and
          other than Disqualified Stock or convertible debt securities that
          have been converted into Disqualified Stock); plus

            (iii) to the extent that any Restricted Investment that was made
          after April 30, 1997 is sold for cash or otherwise liquidated or
          repaid for cash, the amount of cash received in connection therewith
          (or from the sale of Marketable Securities received in connection
          therewith); plus

            (iv) to the extent not already included in such Consolidated Net
          Income of the Company for such period and without duplication;

                (A) 100% of the aggregate amount of cash received as a dividend
              from an Unrestricted Subsidiary;


                                      105
<PAGE>

                (B) 100% of the cash received upon the sale of Marketable
              Securities received as a dividend from an Unrestricted
              Subsidiary; and

                (C) 100% of the net assets of any Unrestricted Subsidiary on
              the date that it becomes a Restricted Subsidiary.

     As of September 30, 1998, the amount that would have been available to
   the Company for Restricted Payments pursuant to this paragraph (c) would
   have been $158.7 million.

     The foregoing provisions will not prohibit:

     (i) the payment of any dividend within 60 days after the date of
   declaration thereof, if at said date of declaration such payment would have
   complied with the provisions of the Indenture;

     (ii) the redemption, repurchase, retirement, defeasance or other
   acquisition of any subordinated Indebtedness or Equity Interests of the
   Company in exchange for, or out of the net cash proceeds of the
   substantially concurrent sale (other than to a Subsidiary of the Company)
   of, other Equity Interests of the Company (other than any Disqualified
   Stock); provided that the amount of any such net cash proceeds that are
   utilized for any such redemption, repurchase, retirement, defeasance or
   other acquisition shall be excluded from clause (c) (ii) of the preceding
   paragraph;

     (iii) the defeasance, redemption, repurchase or other acquisition of
   subordinated Indebtedness (other than intercompany Indebtedness) in
   exchange for, or with the net cash proceeds from an incurrence of,
   Permitted Refinancing Indebtedness;

     (iv) the repurchase, retirement or other acquisition or retirement for
   value of common Equity Interests of the Company or Holdings held by any
   future, present or former employee, director or consultant of the Company
   or any Subsidiary or Holdings issued pursuant to any management equity plan
   or stock option plan or any other management or employee benefit plan or
   agreement; provided, however, that the aggregate amount of Restricted
   Payments made under this clause (iv) does not exceed $1.5 million in any
   calendar year and provided further that cancellation of Indebtedness owing
   to the Company from members of management of the Company or any of its
   Restricted Subsidiaries in connection with a repurchase of Equity Interests
   of the Company will not be deemed to constitute a Restricted Payment for
   purposes of this covenant or any other provision of the Indenture;

     (v) repurchases of Equity Interests deemed to occur upon exercise of
   stock options upon surrender of Equity Interests to pay the exercise price
   of such options;

     (vi) payments to Holdings (A) in amounts equal to the amounts required
   for Holdings to pay franchise taxes and other fees required to maintain its
   legal existence and provide for other operating costs of up to $500,000 per
   fiscal year and (B) in amounts equal to amounts required for Holdings to
   pay federal, state and local income taxes to the extent such income taxes
   are actually due and owing; provided that the aggregate amount paid under
   this clause (B) does not exceed the amount that the Company would be
   required to pay in respect of the income of the Company and its
   Subsidiaries if the Company were a stand alone entity that was not owned by
   Holdings; and

     (vii) other Restricted Payments in an aggregate amount since May 22, 1998
   not to exceed $20.0 million.

     The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries (except to the
extent repaid in cash) in the Subsidiary so designated will be deemed to be
Restricted Payments at the time of such designation and will reduce the amount
available for Restricted Payments under the first paragraph of this covenant.
All such outstanding Investments will be deemed to constitute


                                      106
<PAGE>

Investments in an amount equal to the fair market value of such Investments at
the time of such designation. Such designation will only be permitted if such
Restricted Payment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined by the
Board of Directors whose resolution with respect thereto shall be delivered to
the Trustee. Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by the covenant "Restricted Payments" were computed.


 INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK

     The Indenture provides that the Company will not, and will not permit any
of its Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (including
Acquired Debt) and that the Company will not issue any Disqualified Stock and
will not permit any of its Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company and any Restricted Subsidiary may incur
Indebtedness (including Acquired Debt) or issue shares of preferred stock if
the Fixed Charge Coverage Ratio for the Company's most recently ended four full
fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is
incurred or such preferred stock is issued would have been at least 2.0 to 1.0,
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred, or
the preferred stock had been issued, as the case may be, at the beginning of
such four-quarter period.

     The foregoing limitation will not apply to the incurrence of any of the
following items of Indebtedness (collectively, "Permitted Debt"):

     (i) the incurrence by the Company of additional Indebtedness under Credit
   Facilities (and the guarantee thereof by the Guarantors) in an aggregate
   principal amount outstanding pursuant to this clause (i) at any one time
   (with letters of credit being deemed to have a principal amount equal to
   the maximum potential liability of the Company and its Restricted
   Subsidiaries thereunder), including all Permitted Refinancing Indebtedness
   then outstanding incurred to refund, refinance or replace any other
   Indebtedness incurred pursuant to this clause (i), not to exceed $375.0
   million less the aggregate amount of all Net Proceeds of Asset Sales
   applied to repay any such Indebtedness pursuant to the covenant described
   above under the caption "--Asset Sales";

     (ii) the incurrence by the Company and its Restricted Subsidiaries of the
   Existing Indebtedness;

     (iii) the incurrence by the Company and the Guarantors of $200.0 million
   in aggregate principal amount of each of the Old Notes and the Exchange
   Notes and the Subsidiary Guarantees thereof;

     (iv) the incurrence by the Company or any of its Restricted Subsidiaries
   of Indebtedness represented by Capital Lease Obligations, mortgage
   financings or purchase money obligations, in each case incurred for the
   purpose of financing all or any part of the purchase price or cost of
   construction or improvement of property, plant or equipment used in the
   business of the Company or such Restricted Subsidiary, in an aggregate
   principal amount, including all Permitted Refinancing Indebtedness then
   outstanding incurred to refund, refinance or replace any other Indebtedness
   incurred pursuant to this clause (iv), not to exceed $30.0 million at any
   time outstanding;


                                      107
<PAGE>

     (v) the incurrence by the Company or any of its Restricted Subsidiaries
   of Indebtedness in connection with the acquisition of assets or a new
   Restricted Subsidiary; provided that such Indebtedness was incurred by the
   prior owner of such assets or such Restricted Subsidiary prior to such
   acquisition by the Company or one of its Restricted Subsidiaries and was
   not incurred in connection with, or in contemplation of, such acquisition
   by the Company or one of its Restricted Subsidiaries; and provided further
   that the principal amount (or accreted value, as applicable) of such
   Indebtedness, together with any other outstanding Indebtedness incurred
   pursuant to this clause (v), does not exceed $10.0 million;

     (vi) the incurrence by the Company or any of its Restricted Subsidiaries
   of Permitted Refinancing Indebtedness in exchange for, or the net proceeds
   of which are used to refund, refinance or replace, Indebtedness that was
   permitted by the Indenture to be incurred (other than intercompany
   Indebtedness or Indebtedness incurred pursuant to clause (i) above);

     (vii) Indebtedness incurred by the Company or any of its Restricted
   Subsidiaries constituting reimbursement obligations with respect to letters
   of credit issued in the ordinary course of business in respect of workers'
   compensation claims or self-insurance, or other Indebtedness with respect
   to reimbursement type obligations regarding workers' compensation claims;
   provided, however, that upon the drawing of such letters of credit or the
   incurrence of such Indebtedness, such obligations are reimbursed within 30
   days following such drawing or incurrence;

     (viii) Indebtedness arising from agreements of the Company or a
   Restricted Subsidiary providing for indemnification, adjustment of purchase
   price or similar obligations, in each case, incurred or assumed in
   connection with the disposition of any business, assets or a Subsidiary,
   other than guarantees of Indebtedness incurred by any Person acquiring all
   or any portion of such business, assets or a Subsidiary for the purpose of
   financing such acquisition; provided, however, that:

         (A) such Indebtedness is not reflected on the balance sheet of the
       Company or any Restricted Subsidiary (contingent obligations referred to
       in a footnote to financial statements and not otherwise reflected on the
       balance sheet will not be deemed to be reflected on such balance sheet
       for purposes of this clause (A)); and

         (B) the maximum assumable liability in respect of all such
       Indebtedness shall at no time exceed the gross proceeds including
       noncash proceeds (the fair market value of such noncash proceeds being
       measured at the time received and without giving effect to any
       subsequent changes in value) actually received by the Company and its
       Restricted Subsidiaries in connection with such disposition;

     (ix) the incurrence by the Company or any of its Restricted Subsidiaries
   of intercompany Indebtedness between or among the Company and any of its
   Restricted Subsidiaries; provided, however, that:

         (A) if the Company is the obligor on such Indebtedness, such
       Indebtedness is expressly subordinated to the prior payment in full in
       cash of all Obligations with respect to the Exchange Notes; and

         (B)(1) any subsequent issuance or transfer of Equity Interests that
       results in any such Indebtedness being held by a Person other than the
       Company or one of its Restricted Subsidiaries and (2) any sale or other
       transfer of any such Indebtedness to a Person that is not either the
       Company or one of its Restricted Subsidiaries shall be deemed, in each
       case, to constitute an incurrence of such Indebtedness by the Company or
       such Restricted Subsidiary, as the case may be;

     (x) the incurrence by the Company or any of the Guarantors of Hedging
   Obligations that are incurred for the purpose of:

         (A) fixing, hedging or capping interest rate risk with respect to any
       floating rate Indebtedness that is permitted by the terms of the
       Indenture to be outstanding; or


                                      108
<PAGE>

         (B) protecting the Company and its Restricted Subsidiaries against
       changes in currency exchange rates;

     (xi) the guarantee by the Company or any of the Guarantors of
   Indebtedness of the Company or a Restricted Subsidiary of the Company that
   was permitted to be incurred by another provision of this covenant;

     (xii) the incurrence by the Company's Unrestricted Subsidiaries of
   Non-Recourse Debt, provided, however, that if any such Indebtedness ceases
   to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
   deemed to constitute an incurrence of Indebtedness by a Restricted
   Subsidiary of the Company that was not permitted by this clause (xii), and
   the issuance of preferred stock by Unrestricted Subsidiaries;

     (xiii) obligations in respect of performance and surety bonds and
   completion guarantees provided by the Company or any Restricted
   Subsidiaries in the ordinary course of business; and

     (xiv) the incurrence by the Company or any of its Restricted Subsidiaries
   of additional Indebtedness in an aggregate principal amount (or accreted
   value, as applicable) at any time outstanding, including all Permitted
   Refinancing Indebtedness then outstanding incurred to refund, refinance or
   replace any other Indebtedness incurred pursuant to this clause (xiv), not
   to exceed $50.0 million.

     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xiv) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify, or later reclassify, such item
of Indebtedness in any manner that complies with this covenant. Accrual of
interest, the accretion of accreted value and the payment of interest in the
form of additional Indebtedness will not be deemed to be an incurrence of
Indebtedness for purposes of this covenant.


 LIENS

     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur,
assume or suffer to exist any Lien securing Indebtedness on any asset now owned
or hereafter acquired, or any income or profits therefrom or assign or convey
any right to receive income therefrom, except Permitted Liens.


 ANTILAYERING PROVISION

     The Indenture provides that (i) the Company will not incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the Exchange Notes, and (ii) no Guarantor will
incur, create, issue, assume, guarantee or otherwise become liable for any
Indebtedness that is subordinate or junior in right of payment to any Senior
Debt of a Guarantor and senior in any respect in right of payment to any of the
Subsidiary Guarantees.


 DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES

     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to:

     (i)(A) pay dividends or make any other distributions to the Company or
   any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with
   respect to any other interest or participation in, or measured by, its
   profits, or (B) pay any indebtedness owed to the Company or any of its
   Restricted Subsidiaries;

       (ii) make loans or advances to the Company or any of its Restricted
Subsidiaries; or

                                      109
<PAGE>

     (iii) transfer any of its properties or assets to the Company or any of
   its Restricted Subsidiaries,

except for such encumbrances or restrictions existing under or by reason of:

         (A) the provisions of security agreements that restrict the transfer
       of assets that are subject to a Lien created by such security
       agreements;

         (B) the provisions of agreements governing Indebtedness incurred
       pursuant to clause (v) of the second paragraph of the covenant described
       above under the caption "-- Incurrence of Indebtedness and Issuance of
       Preferred Stock";

         (C) the Indenture, the Notes, the May 1998 Indenture, the May 1998
       Notes, the 1997 Indenture and the 1997 Notes;

         (D) applicable law;

         (E) any instrument governing Indebtedness or Capital Stock of a Person
       acquired by the Company or any of its Restricted Subsidiaries as in
       effect at the time of such acquisition (except to the extent such
       Indebtedness was incurred in connection with or in contemplation of such
       acquisition), which encumbrance or restriction is not applicable to any
       Person, or the properties or assets of any Person, other than the
       Person, or the property or assets of the Person, so acquired, provided
       that, in the case of Indebtedness, such Indebtedness was permitted by
       the terms of the Indenture to be incurred;

         (F) by reason of customary non-assignment provisions in leases entered
       into in the ordinary course of business and consistent with past
       practices;

         (G) purchase money obligations for property acquired in the ordinary
       course of business that impose restrictions of the nature described in
       clause (iii) above on the property so acquired;

         (H) Permitted Refinancing Indebtedness, provided that the restrictions
       contained in the agreements governing such Permitted Refinancing
       Indebtedness are no more restrictive than those contained in the
       agreements governing the Indebtedness being refinanced;

         (I) contracts for the sale of assets, including, without limitation,
       customary restrictions with respect to a Subsidiary pursuant to an
       agreement that has been entered into for the sale or disposition of all
       or substantially all of the Capital Stock or assets of such Subsidiary;

         (J) agreements relating to secured Indebtedness otherwise permitted to
       be incurred pursuant to the covenants described under "Limitations on
       Incurrence of Indebtedness and Issuance of Preferred Stock" and "Liens"
       that limit the right of the debtor to dispose of the assets securing
       such Indebtedness;

         (K) restrictions on cash or other deposits or net worth imposed by
       customers under contracts entered into in the ordinary course of
       business; or

         (L) customary provisions in joint venture agreements and other similar
       agreements entered into in the ordinary course of business.

 MERGER, CONSOLIDATION OR SALE OF ASSETS

     The Indenture provides that the Company may not consolidate or merge with
or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially
all of its properties or assets in one or more related transactions, to another
corporation, Person or entity unless:

     (i) the Company is the surviving corporation or the entity or the Person
   formed by or surviving any such consolidation or merger (if other than the
   Company) or to which such sale, assignment, transfer, lease, conveyance or
   other disposition shall have been made is a corporation organized or
   existing under the laws of the United States, any state thereof or the
   District of Columbia;


                                      110
<PAGE>
     (ii) the entity or Person formed by or surviving any such consolidation
   or merger (if other than the Company) or the entity or Person to which such
   sale, assignment, transfer, lease, conveyance or other disposition shall
   have been made assumes all the obligations of the Company under the
   Exchange Notes and the Indenture pursuant to a supplemental indenture in a
   form reasonably satisfactory to the Trustee;

   
     (iii) immediately after such transaction no Default or Event of Default
   exists; and
    

     (iv) except in the case of a merger of the Company with or into a Wholly
   Owned Restricted Subsidiary of the Company, the Company or the entity or
   Person formed by or surviving any such consolidation or merger (if other
   than the Company), or to which such sale, assignment, transfer, lease,
   conveyance or other disposition shall have been made, after giving pro
   forma effect to such transaction as if such transaction had occurred at the
   beginning of the most recently ended four full fiscal quarters for which
   internal financial statements are available immediately preceding such
   transaction either:

         (A) would be permitted to incur at least $1.00 of additional
       Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth
       in the first paragraph of the covenant described above under the caption
       "-- Incurrence of Indebtedness and Issuance of Preferred Stock"; or

         (B) would have a pro forma Fixed Charge Coverage Ratio that is greater
       than the actual Fixed Charge Coverage Ratio for the same four-quarter
       period without giving pro forma effect to such transaction.

     Notwithstanding the foregoing clause (iv):

     (i) any Restricted Subsidiary may consolidate with, merge into or
   transfer all or part of its properties and assets to the Company; and

     (ii) the Company may merge with an Affiliate that has no significant
   assets or liabilities and was incorporated solely for the purpose of
   reincorporating the Company in another State of the United States so long
   as the amount of Indebtedness of the Company and its Restricted
   Subsidiaries is not increased thereby.


 TRANSACTIONS WITH AFFILIATES

     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, make any payment to, or sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into or make or amend any
transaction, contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of, any Affiliate (each of the foregoing, an
"Affiliate Transaction"), unless:

     (i) such Affiliate Transaction is on terms that are no less favorable to
   the Company or the relevant Restricted Subsidiary than those that would
   have been obtained in a comparable transaction by the Company or such
   Restricted Subsidiary with an unrelated Person; and

   
     (ii) the Company delivers to the Trustee:
    

         (A) with respect to any Affiliate Transaction or series of related
       Affiliate Transactions involving aggregate consideration in excess of
       $5.0 million, a resolution of the Board of Directors set forth in an
       Officers' Certificate certifying that such Affiliate Transaction
       complies with clause (i) above and that such Affiliate Transaction has
       been approved by a majority of the disinterested members of the Board of
       Directors; and

         (B) with respect to any Affiliate Transaction or series of related
       Affiliate Transactions involving aggregate consideration in excess of
       $15.0 million, an opinion as to the fairness to the Holders of such
       Affiliate Transaction from a financial point of view issued by an
       accounting, appraisal or investment banking firm of national standing.

     The foregoing provisions will not prohibit:

                                      111
<PAGE>

     (i) any employment agreement entered into by the Company or any of its
   Restricted Subsidiaries in the ordinary course of business;

   
     (ii) any transaction with a Lehman Investor;

     (iii) any transaction between or among the Company and/or its Restricted
   Subsidiaries;
    

     (iv) transactions between the Company or any of its Restricted
   Subsidiaries, on the one hand, and Lockheed Martin or any of its
   Subsidiaries or a Permitted Joint Venture, on the other hand, on terms that
   are not materially less favorable to the Company or the applicable
   Restricted Subsidiary of the Company than those that could have been
   obtained from an unaffiliated third party; provided that (A) in the case of
   any such transaction or series of related transactions pursuant to this
   clause (iv) involving aggregate consideration in excess of $5.0 million but
   less than $25.0 million, such transaction or series of transactions (or the
   agreement pursuant to which the transactions were executed) was approved by
   the Company's Chief Executive Officer or Chief Financial Officer and (B) in
   the case of any such transaction or series of related transactions pursuant
   to this clause (iv) involving aggregate consideration equal to or in excess
   of $25.0 million, such transaction or series of related transactions (or
   the agreement pursuant to which the transactions were executed) was
   approved by a majority of the disinterested members of the Board of
   Directors;

     (v) any transaction pursuant to and in accordance with the provisions of
   the Transaction Documents as the same are in effect on the Issue Date; and

     (vi) any Restricted Payment that is permitted by the provisions of the
   Indenture described above under the caption "-- Restricted Payments".


 PAYMENTS FOR CONSENT

     The Indenture provides that neither the Company nor any of its
Subsidiaries will, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
any Exchange Notes for or as an inducement to any consent, waiver or amendment
of any of the terms or provisions of the Indenture or the Exchange Notes unless
such consideration is offered to be paid or is paid to all Holders of the
Exchange Notes that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.


 REPORTS

     Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on
an annual and quarterly basis on forms provided for such annual and quarterly
reporting pursuant to rules and regulations promulgated by the Commission, the
Indenture requires the Company to file with the Commission (and provide the
Trustee and Holders with copies thereof, without cost to each Holder, within 15
days after it files them with the Commission):

     (a) within 90 days after the end of each fiscal year, annual reports on
   Form 10-K (or any successor or comparable form) containing the information
   required to be contained therein (or required in such successor or
   comparable form);

     (b) within 45 days after the end of each of the first three fiscal
   quarters of each fiscal year, reports on Form 10-Q (or any successor or
   comparable form);

     (c) promptly from time to time after the occurrence of an event required
   to be therein reported, such other reports on Form 8-K (or any successor or
   comparable form); and

     (d) any other information, documents and other reports which the Company
   would be required to file with the Commission if it were subject to Section
   13 or 15(d) of the Exchange Act;


                                      112
<PAGE>

provided, however, the Company shall not be so obligated to file such reports
with the Commission if the Commission does not permit such filing, in which
event the Company will make available such information to prospective
purchasers of Exchange Notes, in addition to providing such information to the
Trustee and the Holders, in each case within 15 days after the time the Company
would be required to file such information with the Commission, if it were
subject to Sections 13 or 15(d) of the Exchange Act.


 FUTURE SUBSIDIARY GUARANTEES

     The Company's payment obligations under the Exchange Notes is jointly and
severally guaranteed by all of the Company's existing and future Restricted
Subsidiaries, other than Foreign Subsidiaries. The Indenture provides that if
the Company or any of its Subsidiaries shall acquire or create a Subsidiary
(other than a Foreign Subsidiary or an Unrestricted Subsidiary) after the Issue
Date, then such Subsidiary shall execute a Subsidiary Guarantee and deliver an
opinion of counsel, in accordance with the terms of the Indenture. The
Subsidiary Guarantee of each Guarantor ranks pari passu with the guarantees of
the May 1998 Notes and the 1997 Notes and is subordinated to the prior payment
in full of all Senior Debt of such Guarantor, which would include the
guarantees of amounts borrowed under the Senior Credit Facilities. The
obligations of each Guarantor under its Subsidiary Guarantee is limited so as
not to constitute a fraudulent conveyance under applicable law.

     The Indenture provides that no Guarantor may consolidate with or merge
with or into (whether or not such Guarantor is the surviving Person) another
Person (except the Company or another Guarantor) unless:

     (i) subject to the provisions of the following paragraph, the Person
   formed by or surviving any such consolidation or merger (if other than such
   Guarantor) or to which such sale, assignment, transfer, lease, conveyance
   or other disposition shall have been made assumes all the obligations of
   such Guarantor pursuant to a supplemental indenture in form and substance
   reasonably satisfactory to the Trustee, under the Notes and the Indenture;

     (ii) immediately after giving effect to such transaction, no Default or
   Event of Default exists; and

       (iii) the Company:

         (A) would be permitted by virtue of the Company's pro forma Fixed
       Charge Coverage Ratio, immediately after giving effect to such
       transaction, to incur at least $1.00 of additional Indebtedness pursuant
       to the Fixed Charge Coverage Ratio test set forth in the covenant
       described above under the caption "-- Incurrence of Indebtedness and
       Issuance of Preferred Stock"; or

         (B) would have a pro forma Fixed Charge Coverage Ratio that is greater
       than the actual Fixed Charge Coverage Ratio for the same four-quarter
       period without giving pro forma effect to such transaction.

     Notwithstanding the foregoing paragraph:

     (i) any Guarantor may consolidate with, merge into or transfer all or
   part of its properties and assets to the Company; and

     (ii) any Guarantor may merge with an Affiliate that has no significant
   assets or liabilities and was incorporated solely for the purpose of
   reincorporating such Guarantor in another State of the United States so
   long as the amount of Indebtedness of the Company and its Restricted
   Subsidiaries is not increased thereby.

     The Indenture provides that in the event of a sale or other disposition of
all of the assets of any Guarantor, by way of merger, consolidation or
otherwise, or a sale or other disposition of all of the capital stock of any
Guarantor, then such Guarantor (in the event of a sale or other disposition, by
way of such a merger, consolidation or otherwise, of all of the capital stock
of such Guarantor) or the corporation acquiring the property (in the event of a
sale or other disposition of all of the assets of


                                      113
<PAGE>

such Guarantor) will be released and relieved of any obligations under its
Subsidiary Guarantee; provided that the Net Proceeds of such sale or other
disposition are applied in accordance with the applicable provisions of the
Indenture. See "-- Repurchase at Option of Holders -- Asset Sales".


EVENTS OF DEFAULT AND REMEDIES

     The Indenture provides that each of the following constitutes an Event of
Default:

     (i) default for 30 days in the payment when due of interest or Liquidated
   Damages on the Exchange Notes (whether or not prohibited by the
   subordination provisions of the Indenture);

     (ii) default in payment when due of the principal of or premium, if any,
   on the Exchange Notes (whether or not prohibited by the subordination
   provisions of the Indenture);

     (iii) failure by the Company to comply with the provisions described
   under the captions "-- Change of Control", "-- Asset Sales" or "-- Merger,
   Consolidation or Sale of Assets";

     (iv) failure by the Company for 60 days after notice to comply with any
   of its other agreements in the Indenture or the Exchange Notes;

     (v) default under any mortgage, indenture or instrument under which there
   may be issued or by which there may be secured or evidenced any
   Indebtedness for money borrowed by the Company or any of its Restricted
   Subsidiaries (or the payment of which is guaranteed by the Company or any
   of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
   exists, or is created after the Issue Date, which default results in the
   acceleration of such Indebtedness prior to its express maturity and, in
   each case, the principal amount of any such Indebtedness, together with the
   principal amount of any other such Indebtedness the maturity of which has
   been so accelerated, aggregates $10.0 million or more;

     (vi) failure by the Company or any of its Restricted Subsidiaries to pay
   final judgments aggregating in excess of $10.0 million, which judgments are
   not paid, discharged or stayed for a period of 60 days;

     (vii) certain events of bankruptcy or insolvency with respect to the
   Company or any of its Restricted Subsidiaries; and

     (viii) except as permitted by the Indenture, any Subsidiary Guarantee
   shall be held in any judicial proceeding to be unenforceable or invalid.

     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Exchange
Notes may declare all the Exchange Notes to be due and payable immediately;
provided, however, that so long as any Designated Senior Debt is outstanding,
such declaration shall not become effective until the earlier of:

     (i) the day which is five Business Days after receipt by the
   Representatives of Designated Senior Debt of such notice of acceleration;
   or

     (ii) the date of acceleration of any Designated Senior Debt.

Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Company or any
Restricted Subsidiary, all outstanding Exchange Notes will become due and
payable without further action or notice. Holders of the Exchange Notes may not
enforce the Indenture or the Exchange Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Exchange Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Exchange Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest)
if it determines that withholding notice is in their interest.

     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the


                                      114
<PAGE>

premium that the Company would have had to pay if the Company then had elected
to redeem the Exchange Notes pursuant to the optional redemption provisions of
the Indenture, an equivalent premium shall also become and be immediately due
and payable to the extent permitted by law upon the acceleration of the
Exchange Notes. If an Event of Default occurs prior to August 1, 2003 by reason
of any willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding the prohibition on redemption of the
Exchange Notes prior to August 1, 2003, then the premium specified in the
Indenture shall also become immediately due and payable to the extent permitted
by law upon the acceleration of the Exchange Notes.

     The Holders of a majority in aggregate principal amount of the Exchange
Notes then outstanding by notice to the Trustee may on behalf of the Holders of
all of the Exchange Notes waive any existing Default or Event of Default and
its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Exchange Notes.
 

     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.


NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator or stockholder of the
Company, as such, shall have any liability for any obligations of the Company
under the Exchange Notes and the Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder of
Exchange Notes by accepting an Exchange Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Exchange Notes. Such waiver may not be effective to waive liabilities under
the federal securities laws and it is the view of the Commission that such a
waiver is against public policy.


LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Exchange Notes ("Legal
Defeasance") except for:

     (i) the rights of Holders of outstanding Exchange Notes to receive
   payments in respect of the principal of, premium and Liquidated Damages, if
   any, and interest on such Exchange Notes when such payments are due from
   the trust referred to below;

     (ii) the Company's obligations with respect to the Exchange Notes
   concerning issuing temporary Exchange Notes, registration of Exchange
   Notes, mutilated, destroyed, lost or stolen Exchange Notes and the
   maintenance of an office or agency for payment and money for security
   payments held in trust;

     (iii) the rights, powers, trusts, duties and immunities of the Trustee,
   and the Company's obligations in connection therewith; and

     (iv) the Legal Defeasance provisions of the Indenture.

     In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company released with respect to certain covenants that
are described in the Indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or
Event of Default with respect to the Exchange Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the
Exchange Notes.

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     (i) the Company must irrevocably deposit with the Trustee, in trust, for
   the benefit of the Holders of the Exchange Notes, cash in U.S. dollars,
   non-callable Government Securities, or a


                                      115
<PAGE>

   combination thereof, in such amounts as will be sufficient, in the opinion
   of a nationally recognized firm of independent public accountants, to pay
   the principal of, premium and Liquidated Damages, if any, and interest on
   the outstanding Exchange Notes on the stated maturity or on the applicable
   redemption date, as the case may be, and the Company must specify whether
   the Exchange Notes are being defeased to maturity or to a particular
   redemption date;

     (ii) in the case of Legal Defeasance, the Company shall have delivered to
   the Trustee an opinion of counsel in the United States reasonably
   acceptable to the Trustee confirming that:

         (A) the Company has received from, or there has been published by, the
       Internal Revenue Service a ruling; or

         (B) since the Issue Date, there has been a change in the applicable
       federal income tax law, in either case to the effect that, and based
       thereon such opinion of counsel shall confirm that, the Holders of the
       outstanding Exchange Notes will not recognize income, gain or loss for
       federal income tax purposes as a result of such Legal Defeasance and
       will be subject to federal income tax on the same amounts, in the same
       manner and at the same times as would have been the case if such Legal
       Defeasance had not occurred;

     (iii) in the case of Covenant Defeasance, the Company shall have
   delivered to the Trustee an opinion of counsel in the United States
   reasonably acceptable to the Trustee confirming that the Holders of the
   outstanding Exchange Notes will not recognize income, gain or loss for
   federal income tax purposes as a result of such Covenant Defeasance and
   will be subject to federal income tax on the same amounts, in the same
   manner and at the same times as would have been the case if such Covenant
   Defeasance had not occurred;

     (iv) no Default or Event of Default shall have occurred and be continuing
   on the date of such deposit (other than a Default or Event of Default
   resulting from the borrowing of funds to be applied to such deposit) or
   insofar as Events of Default from bankruptcy or insolvency events are
   concerned, at any time in the period ending on the 91st day after the date
   of deposit;

     (v) such Legal Defeasance or Covenant Defeasance will not result in a
   breach or violation of, or constitute a default under any material
   agreement or instrument (other than the Indenture) to which the Company or
   any of its Subsidiaries is a party or by which the Company or any of its
   Subsidiaries is bound;

     (vi) the Company must have delivered to the Trustee an opinion of counsel
   to the effect that after the 91st day following the deposit, the trust
   funds will not be subject to the effect of any applicable bankruptcy,
   insolvency, reorganization or similar laws affecting creditors' rights
   generally;

     (vii) the Company must deliver to the Trustee an Officers' Certificate
   stating that the deposit was not made by the Company with the intent of
   preferring the Holders of Exchange Notes over the other creditors of the
   Company with the intent of defeating, hindering, delaying or defrauding
   creditors of the Company or others; and

     (viii) the Company must deliver to the Trustee an Officers' Certificate
   and an opinion of counsel, each stating that all conditions precedent
   provided for relating to the Legal Defeasance or the Covenant Defeasance
   have been complied with.


TRANSFER AND EXCHANGE

     A Holder may transfer or exchange Exchange Notes in accordance with the
Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company is not required to transfer or exchange
any Note selected for redemption. Also, the Company is not required to transfer
or exchange any Note for a period of 15 days before a selection of Exchange
Notes to be redeemed.


                                      116
<PAGE>

     The registered Holder of a Note will be treated as the owner of it for all
purposes.

AMENDMENT, SUPPLEMENT AND WAIVER

     Except as provided in the next two succeeding paragraphs, the Indenture or
the Exchange Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the Exchange Notes then
outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for, Exchange Notes), and
any existing default or compliance with any provision of the Indenture or the
Exchange Notes may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Exchange Notes (including consents
obtained in connection with a tender offer or exchange offer for Exchange
Notes).

     Without the consent of each Holder affected, an amendment or waiver may
not (with respect to any Notes held by a non-consenting Holder):

     (i) reduce the principal amount of Exchange Notes whose Holders must
   consent to an amendment, supplement or waiver;

     (ii) reduce the principal of or change the fixed maturity of any Note or
   alter the provisions with respect to the redemption of the Exchange Notes
   (other than provisions relating to the covenants described above under the
   caption "-- Repurchase at the Option of Holders");

     (iii) reduce the rate of or change the time for payment of interest on
   any Note;

     (iv) waive a Default or Event of Default in the payment of principal of
   or premium and Liquidated Damages, if any, or interest on the Exchange
   Notes (except a rescission of acceleration of the Exchange Notes by the
   Holders of at least a majority in aggregate principal amount of the
   Exchange Notes and a waiver of the payment default that resulted from such
   acceleration);

     (v) make any Note payable in money other than that stated in the Exchange
   Notes;

     (vi) make any change in the provisions of the Indenture relating to waivers
   of past Defaults or the rights of Holders of Exchange Notes to receive
   payments of principal of or premium and Liquidated Damages, if any, or
   interest on the Exchange Notes;

     (vii) waive a redemption payment with respect to any Note (other than a
   payment required by one of the covenants described above under the caption
   "-- Repurchase at the Option of Holders"); or

     (viii) make any change in the foregoing amendment and waiver provisions.
 

     In addition, any amendment to the provisions of Article 10 of the
Indenture (which relates to subordination) requires the consent of the Holders
of at least 75% in aggregate principal amount of the Exchange Notes then
outstanding if such amendment would adversely affect the rights of Holders of
Exchange Notes.

     Notwithstanding the foregoing, without the consent of any Holder of
Exchange Notes, the Company and the Trustee may amend or supplement the
Indenture or the Exchange Notes to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated
Exchange Notes, to provide for the assumption of the Company's obligations to
Holders of Exchange Notes in the case of a merger or consolidation, to make any
change that would provide any additional rights or benefits to the Holders of
Exchange Notes or that does not adversely affect the legal rights under the
Indenture of any such Holder, or to comply with requirements of the Commission
in order to effect or maintain the qualification of the Indenture under the
Trust Indenture Act.

CONCERNING THE TRUSTEE

     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain


                                      117
<PAGE>

property received in respect of any such claim as security or otherwise. The
Trustee is permitted to engage in other transactions; however, if it acquires
any conflicting interest it must eliminate such conflict within 90 days, apply
to the Commission for permission to continue or resign.

     The Holders of a majority in principal amount of the then outstanding
Exchange Notes have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. The Indenture provides that in case an Event of
Default shall occur (which shall not be cured), the Trustee will be required,
in the exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any Holder of Exchange Notes, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.


ADDITIONAL INFORMATION

     Anyone who receives this prospectus may obtain a copy of the Indenture and
Registration Rights Agreement without charge by writing to L-3 Communications
Corporation, 600 Third Avenue, New York, New York 10016, Attention: Vice
President -- Finance.


BOOK-ENTRY, DELIVERY AND FORM

     The certificates representing the Exchange Notes will be issued in fully
registered form and will be deposited with the Trustee as custodian for the
Depository Trust Company, New York, New York (the "Depository") and registered
in the name of a nominee of the Depository.

     The Notes may be presented for registration of transfer and exchange at
the offices of the Registrar.


DEPOSITORY PROCEDURES

     The Depository has advised the Company that the Depository is a
limited-purpose trust company created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the
clearance and settlement of transactions in those securities between
Participants through electronic book-entry changes in accounts of Participants.
The Participants include securities brokers and dealers (including the Initial
Purchasers), banks, trust companies, clearing corporations and certain other
organizations. Access to the Depository's system is also available to other
entities such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly (collectively, "Indirect Participants"). Persons who are not
Participants may beneficially own securities held by or on behalf of the
Depository only through the Participants or Indirect Participants. The
ownership interest and transfer of ownership interest of each actual purchaser
of each security held by or on behalf of the Depository are recorded on the
records of the Participants and Indirect Participants.

     The Depository has also advised the Company that pursuant to procedures
established by it, (i) upon deposit of the Global Exchange Notes, the
Depository will credit the accounts of Participants designated by the Initial
Purchasers with portions of the principal amount of Global Exchange Notes and
(ii) ownership of such interests in the Global Exchange Notes will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depository (with respect to Participants) or by Participants
and the Indirect Participants (with respect to other owners of beneficial
interests in the Global Exchange Notes).

     Investors in the Global Note may hold their interests therein directly
through the Depository, if they are Participants in such system, or indirectly
through organizations (including Euroclear and CEDEL) that are Participants in
such system. Investors in the Regulation S Global Note must initially hold
their interests therein through Euroclear or CEDEL, if they are participants in
such systems, or indirectly through organizations that are participants in such
systems. After the expiration of the Restricted Period (but not earlier),
investors may also hold interests in the Regulation S Global Note


                                      118
<PAGE>

through organizations other than Euroclear and CEDEL that are Participants in
the Depository system. Euroclear and CEDEL will hold interests in the
Regulation S Global Note on behalf of their Participants through customers'
securities accounts in their respective names on the books of their respective
depositories, which are Morgan Guaranty Trust Company of New York, Brussels
office, as operator of Euroclear, and Citibank, N.A. as operator of CEDEL. The
depositories, in turn, will hold such interests in the Regulation S Global Note
in customers' securities accounts in the depositories' names on the books of
the Depository. All interests in a Global Note, including those held through
Euroclear or CEDEL, may be subject to the procedures and requirements of the
Depository. Those interests held by Euroclear or CEDEL may be also be subject
to the procedures and requirements of such system.

     The laws of some states require that certain persons take physical
delivery in definitive form of securities that they own. Consequently, the
ability to transfer beneficial interest in a Global Note to such persons may be
limited to that extent. Because the Depository can act only on behalf of
Participants, which in turn act on behalf of Indirect Participants and certain
banks, the ability of a person having a beneficial interest in a Global Note to
pledge such interest to persons or entities that do not participate in the
Depository system, or otherwise take actions in respect of such interests, may
be affected by the lack of physical certificate evidencing such interests. For
certain other restrictions on the transferability of the Notes see, "--
Exchange of Book-Entry Notes for Certificated Notes".

     EXCEPT AS DESCRIBED BELOW, OWNERS OF INTERESTS IN THE GLOBAL EXCHANGE
NOTES WILL NOT HAVE EXCHANGE NOTES REGISTERED IN THEIR NAMES, WILL NOT RECEIVE
PHYSICAL DELIVERY OF EXCHANGE NOTES IN CERTIFICATED FORM AND WILL NOT BE
CONSIDERED THE REGISTERED OWNERS OR HOLDERS THEREOF UNDER THE INDENTURE FOR ANY
PURPOSE.

     Payments in respect of the principal and premium and Liquidated Damages,
if any, and interest on a Global Note registered in the name of the Depository
or its nominee will be payable by the Trustee to the Depository or its nominee
in its capacity as the registered Holder under the Indenture. Under the terms
of the Indenture, the Company and the Trustee will treat the persons in whose
names the Exchange Notes, including the Global Exchange Notes, are registered
as the owners thereof for the purpose of receiving such payments and for any
and all other purposes whatsoever. Consequently, neither the Company, the
Trustee nor any agent of the Company or the Trustee has or will have any
responsibility or liability for (i) any aspect of the Depository's records or
any Participant's or Indirect Participant's records relating to or payments
made on account of beneficial ownership interests in the Global Exchange Notes,
or for maintaining, supervising or reviewing any of the Depository's records or
any Participant's or Indirect Participant's records relating to the beneficial
ownership interests in the Global Exchange Notes or (ii) any other matter
relating to the actions and practices of the Depository or any of its
Participants or Indirect Participants.

     The Depository has advised the Company that its current practices, upon
receipt of any payment in respect of securities such as the Exchange Notes
(including principal and interest), is to credit the accounts of the relevant
Participants with the payment on the payment date, in amounts proportionate to
their respective holdings in principal amount of beneficial interests in the
relevant security such as the Global Exchange Notes as shown on the records of
the Depository. Payments by Participants and the Indirect Participants to the
beneficial owners of Exchange Notes will be governed by standing instructions
and customary practices and will not be the responsibility of the Depository,
the Trustee or the Company. Neither the Company nor the Trustee will be liable
for any delay by the Depository or its Participants in identifying the
beneficial owners of the Exchange Notes, and the Company and the Trustee may
conclusively rely on and will be protected in relying on instructions from the
Depository or its nominee as the registered owner of the Exchange Notes for all
purposes.

     Except for trades involving only Euroclear and CEDEL participants,
interests in the Global Exchange Notes will trade in the Depository's Same-Day
Funds Settlement System and secondary market trading activity in such interests
will, therefore, settle in immediately available funds, subject in all cases to
the rules and procedures of the Depository and its participants.


                                      119
<PAGE>

     Transfers between Participants in the Depository will be effected in
accordance with the Depository's procedures, and will be settled in same-day
funds. Transfers between participants in Euroclear and CEDEL will be effected
in the ordinary way in accordance with their respective rules and operating
procedures.

     Subject to compliance with the transfer restrictions applicable to the
Exchange Notes described herein, crossmarket transfers between Participants in
the Depository, on the one hand, and Euroclear or CEDEL participants, on the
other hand, will be effected through the Depository in accordance with the
Depository's rules on behalf of Euroclear or CEDEL, as the case may be, by its
respective depository; however, such cross-market transactions will require
delivery of instructions to Euroclear or CEDEL, as the case may be, by the
counterparty in such system in accordance with the rules and procedures and
within the established deadlines (Brussels time) of such system. Euroclear or
CEDEL, as the case may be, will, if the transaction meets its settlement
requirements, deliver instructions to its respective depository to take action
to effect final settlement on its behalf by delivering or receiving interests
in the relevant Global Exchange Note in the Depository, and making or receiving
payment in accordance with normal procedures for same-day fund settlement
applicable to the Depository. Euroclear participants and CEDEL participants may
not deliver instructions directly to the Depositaries for Euroclear or CEDEL.

     Because of time zone differences, the securities accounts of a Euroclear
or CEDEL participant purchasing an interest in a Global Exchange Note from a
Participant in the Depository will be credited, and any such crediting will be
reported to the relevant Euroclear or CEDEL participant, during the securities
settlement processing day (which must be a business day for Euroclear or CEDEL)
immediately following the settlement date of the Depository. Cash received in
Euroclear or CEDEL as a result of sales of interests in a Global Exchange Note
by or through a Euroclear or CEDEL participant to a Participant in the
Depository will be received with value on the settlement date of the Depository
but will be available in the relevant Euroclear or CEDEL cash account only as
of the business day for Euroclear or CEDEL following the Depository's
settlement date.

     The Depository has advised the Company that it will take any action
permitted to be taken by a Holder of Exchange Notes only at the direction of
one or more Participants to whose account the Depository interests in the
Global Exchange Notes are credited and only in respect of such portion of the
aggregate principal amount of the Exchange Notes as to which such Participant
or Participants has or have given direction. However, if there is an Event of
Default under the Exchange Notes, the Depository reserves the right to exchange
Exchange Global Notes for legended Exchange Notes in certificated form, and to
distribute such Exchange Notes to its Participants.

     The information in this section concerning the Depository, Euroclear and
CEDEL and their book-entry systems has been obtained from sources that the
Company believes to be reliable, but the Company takes no responsibility for
the accuracy thereof.

     Although the Depository, Euroclear and CEDEL have agreed to the foregoing
procedures to facilitate transfers of interests in the Global Note among
participants in the Depository, Euroclear and CEDEL, they are under no
obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. None of the Company, the Initial
Purchasers or the Trustee will have any responsibility for the performance by
the Depository, Euroclear or CEDEL or their respective participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.


 EXCHANGE OF BOOK-ENTRY NOTES FOR CERTIFICATED NOTES

     A Global Note is exchangeable for definitive Exchange Notes in registered
certificated form if (i) the Depository (A) notifies the Company that it is
unwilling or unable to continue as depository for the Global Note and the
Company thereupon fails to appoint a successor depository or (B) has ceased to
be a clearing agency registered under the Exchange Act or (ii) the Company, at
its option, notifies the Trustee in writing that it elects to cause issuance of
the Exchange Notes in certificated form. In addition, beneficial interests in a
Global Note may be exchanged for certificated Exchange Notes upon


                                      120
<PAGE>

request but only upon at least 20 days prior written notice given to the
Trustee by or on behalf of the Depository in accordance with customary
procedures. In all cases, certificated Exchange Notes delivered in exchange for
any Global Note or beneficial interest therein will be registered in names, and
issued in any approved denominations, requested by or on behalf of the
Depository (in accordance with its customary procedures).


 CERTIFICATED EXCHANGE NOTES

     Subject to certain conditions, any person having a beneficial interest in
the Global Note may, upon request to the Trustee, exchange such beneficial
interest for Exchange Notes in the form of certificated Notes. Upon any such
issuance, the Trustee is required to register such certificated Exchange Notes
in the name of, and cause the same to be delivered to, such person or persons
(or the nominee of any thereof). In addition, if (i) the Company notifies the
Trustee in writing that the Depository is no longer willing or able to act as a
depository and the Company is unable to locate a qualified successor within 90
days or (ii) the Company, at its option, notifies the Trustee in writing that
it elects to cause the issuance of Exchange Notes in the form of certificated
Exchange Notes under the Indenture, then, upon surrender by the Global Note
Holder of its Global Note, Exchange Notes in such form will be issued to each
person that the Global Note Holder and the Depository identify as being the
beneficial owner of the related Exchange Notes.

     Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depository in identifying the beneficial owners of
Exchange Notes and the Company and the Trustee may conclusively rely on, and
will be protected in relying on, instructions from the Global Note Holder or
the Depository for all purposes.


 SAME DAY SETTLEMENT AND PAYMENT

     The Indenture requires that payments in respect of the Exchange Notes
represented by the Global Note (including principal, premium, if any, interest
and Liquidated Damages, if any) be made by wire transfer of immediately
available funds to the accounts specified by the Global Note Holder. With
respect to certificated Exchange Notes, the Company will make all payments of
principal, premium, if any, interest and Liquidated Damages, if any, by wire
transfer of immediately available funds to the accounts specified by the
Holders thereof or, if no such account is specified, by mailing a check to each
such Holder's registered address. The Company expects that secondary trading in
the certificated Exchange Notes will also be settled in immediately available
funds.


REGISTRATION RIGHTS; LIQUIDATED DAMAGES

     The Company, the Guarantors and the Initial Purchasers entered into the
Registration Rights Agreement on or prior to the Issue Date. Pursuant to the
Registration Rights Agreement, the Company and the Guarantors agreed to file
with the Commission the Exchange Offer Registration Statement on the
appropriate form under the Securities Act with respect to the Exchange Notes.
Upon the effectiveness of the Exchange Offer Registration Statement, the
Company will offer to the Holders of Transfer Restricted Securities pursuant to
the Exchange Offer who are able to make certain representations the opportunity
to exchange their Transfer Restricted Securities for Exchange Notes. If:

     (i) the Company and the Guarantors are not required to file the Exchange
   Offer Registration Statement or permitted to consummate the Exchange Offer
   because the Exchange Offer is not permitted by applicable law or Commission
   policy; or

     (ii) any Holder of Transfer Restricted Securities notifies the Company
   prior to the 20th day following consummation of the Exchange Offer that:

         (A) it is prohibited by law or Commission policy from participating in
       the Exchange Offer; or


                                      121
<PAGE>

         (B) that it may not resell the Exchange Notes acquired by it in the
       Exchange Offer to the public without delivering a prospectus and the
       prospectus contained in the Exchange Offer Registration Statement is not
       appropriate or available for such resales; or

         (C) that it is a broker-dealer and owns Old Notes acquired directly
       from the Company or an affiliate of the Company,

the Company and the Guarantors will file with the Commission a Shelf
Registration Statement to cover resales of the Exchange Notes by the Holders
thereof who satisfy certain conditions relating to the provision of information
in connection with the Shelf Registration Statement. The Company and the
Guarantors will use their best efforts to cause the applicable registration
statement to be declared effective as promptly as possible by the Commission.

     For purposes of the foregoing, "Transfer Restricted Securities" means each
Old Note until:

     (i) the date on which such Old Note has been exchanged by a person other
   than a broker-dealer for an Exchange Note in the Exchange Offer;

     (ii) following the exchange by a broker-dealer in the Exchange Offer of
   an Old Note for an Exchange Note, the date on which such Exchange Note is
   sold to a purchaser who receives from such broker-dealer on or prior to the
   date of such sale a copy of the prospectus contained in the Exchange Offer
   Registration Statement;

     (iii) the date on which such Old Note has been effectively registered
   under the Securities Act and disposed of in accordance with the Shelf
   Registration Statement; or

     (iv) the date on which such Old Note is distributed to the public
   pursuant to Rule 144 under the Act.

       The Registration Rights Agreement provides that:

     (i) the Company and the Guarantors will file an Exchange Offer
   Registration Statement with the Commission on or prior to 90 days after the
   Issue Date;

     (ii) the Company and the Guarantors will use their best efforts to have
   the Exchange Offer Registration Statement declared effective by the
   Commission on or prior to 150 days after the Issue Date;

     (iii) unless the Exchange Offer would not be permitted by applicable law
   or Commission policy, the Company and the Guarantors will commence the
   Exchange Offer and use their best efforts to issue on or prior to 30
   business days after the date on which the Exchange Offer Registration
   Statement was declared effective by the Commission, new Exchange Notes in
   exchange for all new Exchange Notes tendered prior thereto in the Exchange
   Offer; and

     (iv) if obligated to file the Shelf Registration Statement, the Company
   and the Guarantors will use their best efforts to file the Shelf
   Registration Statement with the Commission on or prior to 30 days after
   such filing obligation arises and to cause the Shelf Registration Statement
   to be declared effective by the Commission on or prior to 90 days after
   such obligation arises.

       If:

         (A) the Company and the Guarantors fail to file any of the
       Registration Statements required by the Registration Rights Agreement on
       or before the date specified above for such filing;

         (B) any of such Registration Statements is not declared effective by
       the Commission on or prior to the date specified for such effectiveness
       (the "Effectiveness Target Date");

         (C) the Company and the Guarantors fail to consummate the Exchange
       Offer within 30 business days of the Effectiveness Target Date with
       respect to the Exchange Offer Registration Statement; or


                                      122
<PAGE>

         (D) the Shelf Registration Statement or the Exchange Offer
       Registration Statement is declared effective but thereafter ceases to be
       effective or usable in connection with resales of Transfer Restricted
       Securities during the periods specified in the Registration Rights
       Agreement (each such event referred to in clauses (A) through (D) above
       a "Registration Default"),


then the Company and the Guarantors will pay Liquidated Damages to each Holder
of Old Notes, with respect to the first 90-day period immediately following the
occurrence of the first Registration Default in an amount equal to $.05 per
week per $1,000 principal amount of Old Notes held by such Holder. The amount
of the Liquidated Damages will increase by an additional $.05 per week per
$1,000 principal amount of Old Notes with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum amount
of Liquidated Damages of $.50 per week per $1,000 principal amount of Old
Notes. All accrued Liquidated Damages will be paid by the Company and the
Guarantors on each Damages Payment Date to the Global Note Holder by wire
transfer of immediately available funds or by federal funds check and to
Holders of certificated Old Notes by wire transfer to the accounts specified by
them or by mailing checks to their registered addresses if no such accounts
have been specified. Following the cure of all Registration Defaults, the
accrual of Liquidated Damages will cease.


     Holders of Old Notes will be required to make certain representations to
the Company and the Guarantors (as described in the Registration Rights
Agreement) in order to participate in the Exchange Offer and will be required
to deliver information to be used in connection with the Shelf Registration
Statement and to provide comments on the Shelf Registration Statement within
the time periods set forth in the Registration Rights Agreement in order to
have their Old Notes included in the Shelf Registration Statement and benefit
from the provisions regarding Liquidated Damages set forth above.

obligation or otherwise, or redeemable at the option of the Holder thereof, in

the terms of such Capital Stock provide that the Company may not repurchase or
redeem any such Capital Stock pursuant to such provisions unless such

caption "-- Certain Covenants -- Restricted Payments"; and provided further,
that if such Capital Stock is issued to any plan for the benefit of employees
of the Company or its Subsidiaries or by any such plan to such employees, such

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE

     The exchange of Old Notes for Exchange Notes will not constitute a
recognition event for federal income tax purposes. Consequently, no gain or
loss will be recognized by holders upon receipt of the Exchange Notes. For
purposes of determining gain or loss upon the subsequent sale or exchange of
Exchange Notes, a Holder's basis in Exchange Notes will be the same as such
Holder's basis in the Old Notes exchanged therefor. Holders will be considered
to have held the Exchange Notes from the time of their original acquisition of
the Old Notes.

     IN ANY EVENT, PERSONS CONSIDERING THE EXCHANGE OF OLD NOTES FOR EXCHANGE
NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED STATES
FEDERAL INCOME TAX CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS AS WELL
AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTIONS.


                             PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. This
prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Old Notes where such Old Notes were acquired as a result of
market-making activities or other trading activities. To the extent any such
broker-dealer participates in the Exchange Offer and so notifies the Company,
or causes the Company to be so notified in writing, the Company has agreed that
a period of 180 days after the date of this prospectus, it will make this
prospectus, as amended or supplemented, available to such broker-dealer for use
in connection with any such resale, and will promptly send additional copies of
this prospectus and any amendment or supplement to this prospectus to any
broker-dealer that requests such documents in the Letter of Transmittal.

     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at prevailing market prices at the time of resale, at prices
related to such prevailing market prices or at negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
such broker-dealer or the purchasers or any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, and any profit on any
such resale of Exchange Notes and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that, by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

     The Company has agreed to pay all expenses incident to the Exchange Offer
(other than commissions and concessions of any broker-dealers), subject to
certain prescribed limitations, and will indemnify the holders of the Old Notes
against certain liabilities, including certain liabilities that may arise under
the Securities Act.

     By its acceptance of the Exchange Offer, any broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer hereby agrees to notify the
Company prior to using the prospectus in connection with the sale or transfer
of Exchange Notes, and acknowledges and agrees that, upon receipt of notice
from the Company of the happening of any event which makes any statement in
this prospectus untrue in any material respect or which requires the making of
any changes in this prospectus in order to make the statements therein not
misleading or which may impose upon the Company disclosure obligations that may
have a material adverse effect on the Company (which notice the Company agrees
to deliver promptly to such broker-dealer), such broker-dealer will


                                      136
<PAGE>

suspend use of this prospectus until the Company has notified such
broker-dealer that delivery of this prospectus may resume and has furnished
copies of any amendment or supplement to this prospectus to such broker-dealer.

     Certain legal matters will be passed upon for the Company by Simpson

in April 1993 (collectively, the "Business" or the "Predecessor Company"). The
combined financial statements of the Predecessor Company reflect the
Businesses' results of operations and cash flows included in Lockheed Martin's
historical financial statements. Significant intercompany and inter-business
transactions and balances have been eliminated.

     The Company is a wholly owned subsidiary of L-3 Comunications Holdings,
Inc. ("Holdings"). Holdings owns all of the authorized, issued and outstanding
common stock, par value $0.01 per share, of L-3 Communications. Holdings has no
other assets or liabilities and conducts no operations other than through its
subsidiary, L-3. Certain obligations of the Company have been fully, jointly
and severally guaranteed by substantially all of its subsidiaries.
Non-guarantor subsidiaries are not significant to the consolidated financial
position, results of operations and cash flows of the Company.

     The accompanying unaudited condensed consolidated (combined) financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information and with the instructions to Form
10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission
("SEC"); accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. The combined statement of operations for the three months ended
March 31, 1997 has been derived from the audited financial statements of the
Predecessor Company for such period. In the opinion of management, all
adjustments (consisting of normal recurring accruals) considered necessary for
a fair presentation of the results for the interim periods presented have been
included. The results of operations for the interim periods are not necessarily
indicative of results for the full year. For further information, the interim
financial statements should be read in conjunction with the Company's
Consolidated (Combined) Financial Statements as of December 31, 1997 and notes
thereto included in L-3 Communications' Annual Report on Form 10-K for fiscal
year ended December 31, 1997, as amended by Form 10-K/A.

     The Company is a supplier of sophisticated secure communications systems
and specialized communication products including secure, high data rate
communication systems, microwave components, avionics and ocean systems,
telemetry, instrumentation and space products. The Company's customers include
the Department of Defense (the "DoD"), selected U.S. Government intelligence
agencies, major aerospace/defense prime contractors and commercial customers.

     Substantially all the Company's products are sold to agencies of the U.S.
Government, primarily the DoD, to foreign government agencies or to prime
contractors or subcontractors thereof. All domestic government contracts and
subcontracts of the Businesses are subject to audit and various cost controls,
and include standard provisions for termination for the convenience of the U.S.
Government. Multi-year U.S. Government contracts and related orders are subject
to cancellation if funds for contract performance for any subsequent year
become unavailable. Foreign government contracts generally include comparable
provisions relating to termination for the convenience of the government.

2. COMMON STOCK INITIAL PUBLIC OFFERING


     On May 19, 1998, Holdings sold 6.9 million shares of its Common Stock in
an Initial Public Offering ("IPO") representing 25.2% of Holdings' Common
Stock. The net proceeds of the IPO amounted to $139,500 and were contributed by
Holdings to L-3 Communications. After the completion of the IPO, the Lehman
Partnership and Lockheed Martin owned 36.6% and 24.9%, respectively, of the
outstanding shares of Holdings' Common Stock.


3. ACQUISITIONS


     On August 13, 1998, the Company purchased all of the outstanding stock of
SPD Technologies, Inc. ("SPD") for $230,000 of cash, subject to adjustment
based on final closing adjusted net assets. On March 30, 1998 the Company
purchased the assets of the Ocean Systems business ("Ocean Systems") of
AlliedSignal, Inc. for $67,500 of cash. On March 4, 1998, the Company purchased
the assets of ILEX Systems ("ILEX") for $51,900 of cash, subject to adjustment
based on closing net assets, and additional consideration based on
post-acquisition performance of ILEX. On February 5, 1998, the Company
purchased the assets of Satellite Transmission Systems division ("STS") of
California Microwave, Inc. for $27,000 of cash, subject to adjustment based
upon closing net assets.


     Additionally, during the nine months ended September 30, 1998, the Company
purchased five other companies for an aggregate purchase price of $24,750 paid
in cash, before adjustments, as appropriate, based on closing date net assets
and additional consideration based on post-acquisition performance. These
acquisitions, both individually and in the aggregate are not expected to have a
material effect on the results of operations or financial position of the
Company.


     The Company financed the above-mentioned acquisitions using cash from
operations, the contribution by Holdings to the Company of the net proceeds
from Holdings IPO and borrowings. All of the acquisitions have been accounted
for as purchase business combinations and are included in the Company's results
of operation from their effective dates.


     The assets and liabilities recorded in connection with the acquisitions of
SPD, Ocean Systems, ILEX and STS are based upon preliminary estimates. Actual
adjustments will be based on the final purchase prices and the final appraisals
and other analyses of fair values which are in process. Management does not
expect that differences between the preliminary and final purchase price
allocations will have a material impact on the Company's financial position or
results of operations. The assets and liabilities recorded in connection with
the acquisitions of SPD, Ocean Systems, ILEX and STS were $318,825 and $77,557,
$136,670 and $68,000, $58,370 and $3,939, and $34,471 and $6,949, respectively.
 


     Had the L-3 Acquisition and the SPD, Ocean Systems, ILEX and STS
acquisitions and the related financing transactions occurred on January 1,
1997, the unaudited pro forma sales and net income for the nine months ended
September 30, 1998 and 1997 would have been $834,500, $17,400, and $758,700 and
$2,800, respectively. The pro forma results are based on various assumptions
and are not necessarily indicative of what would have occurred had the
acquisitions and the related financing transactions been consummated on January
1, 1997.

     In February 1998, an amendment to the Senior Credit Facilities increased
the Revolving Credit Facility thereunder to $200,000. During the third quarter
of 1998, the Senior Credit Facilities were further amended to add a Revolving
364 Day Credit Facility for $185,000. The Revolving 364 Day Credit Facility
expires 364 days after the closing of the amendment, at which time the Company
may (i) request that the creditors extend it for one additional 364 day period
or (ii) exercise an option to convert any or all of the borrowings outstanding
thereunder into term loans which amortize over a two year period beginning
March 31, 2001, and must be paid in full no later than March 31, 2003.
Accordingly, borrowings under the Revolving 364 Day Credit Facility are
classified as a long term obligation. Approximately $28,330 of the Revolving
Credit Facility and $175,000 of the Revolving 364 Day Credit Facility are
available at September 30, 1998, net of outstanding letters of credit of
$26,670 drawn against the Revolving Credit Facility. The Revolving Credit
Facility and the Revolving 364 Day Credit Facility comprise the Revolving
Credit Facilities.

   
     In May 1998, L-3 Communications sold $180,000 of 8 1/2% Senior Subordinated
Notes (the "May 1998 Notes") due May 15, 2008 with interest payable
semi-annually on May 15 and November 15 of each year, commencing November 15,
1998. The May 1998 Notes are redeemable at the option of L-3 Communications, in
whole or in part, at any time on or after May 15, 2003, at various redemption
prices plus accrued and unpaid interest to the applicable redemption date. In
addition, prior to

May 15, 2001, L-3 Communications may redeem up to 35% of the aggregate
principal amount of May 1998 Notes at a redemption price of 108.500% of the
principal amount thereof, plus accrued and unpaid interest to the redemption
date with the net cash proceeds of one or more equity offerings by Holdings
that are contributed to L-3 Communications as common equity capital.

   
     The Senior Credit Facilities, the $225,000 of 10 3/8% Senior Subordinated
Notes due May 1, 2007 (the "1997 Notes") and the May 1998 Notes agreements
contain financial and restrictive covenants that limit, among other things, the
ability of the Company to borrow additional funds, dispose of assets, or pay
cash dividends. The Senior Credit Facilities contain financial covenants which
require that (i) the Company's debt ratio, as defined, be less than or equal to
5.00 for the quarter ended September 30, 1998, and that the maximum allowable
debt ratio, as defined therein, thereafter declines over time to less than or
equal to 3.25 for the quarters ending September 30, 2002 and thereafter, and
(ii) the Company's interest coverage ratio, as defined, be greater than or
equal to 2.00 for the quarter ended September 30, 1998, and that the minimum
allowable interest coverage ratio, as defined therein, thereafter increases
over time to greater than or equal to 3.00 for the quarters ending September
30, 2002 and thereafter. Through and at September 30, 1998 the Company was in
compliance with these covenants at all times.
    

     The indebtedness under the Senior Credit Facilities is guaranteed by
Holdings and by certain of L-3 Communications' direct domestic subsidiaries.
The payment of principal, premium, if any, and interest on the 1997 Notes and
May 1998 Notes is unconditionally guaranteed, on an unsecured senior
subordinated basis, jointly and severally, by substantially all of L-3
Communications' domestic subsidiaries, all of which are wholly-owned
subsidiaries.


6. STOCK OPTIONS

     On May 1, 1998, Holdings granted options to certain employees of the
Company to purchase 285,370 shares of Common Stock at an exercise price of
$22.00 per share and on terms substantially similar to the 1997 Options granted
in 1997.

     On August 14, 1998, Holdings granted options to certain employees of the
Company to purchase 142,200 shares of Common Stock at an exercise price of
$32.75 per share and on terms substantially similar to the 1997 Options granted
in 1997.

     During the nine months ended September 30, 1998, the Company recorded an
income tax benefit of $524 directly to shareholders' equity related to the
exercise of Holdings' stock options.

     Prior to the L-3 Acquisition, the Predecessor Company participated in the
Lockheed Martin cash management system, under which all cash was received and
all payments were made by Lockheed Martin. For purposes of the statement of
cash flows, all transactions with Lockheed Martin were deemed to have been
settled in cash at the time they were recorded by the Predecessor Company.

8. NEW ACCOUNTING PRONOUNCEMENTS

     On January 1, 1998 the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 130, "Reporting Comprehensive Income". SFAS No. 130
established standards for reporting and display of comprehensive income and its
components (revenue, expenses, gains and losses) in a full set of general
purpose financial statements. For the nine months ended September 30, 1998,
comprehensive income was $19,038 and was comprised of net income of $18,690 and
other comprehensive income of $348 relating to foreign currency translations.
For the nine months ended September 30, 1997, there were no differences between
net income and comprehensive income.

     In September 1997, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 131, "Disclosure about Segments of an Enterprise and Related
Information". SFAS No. 131 establishes accounting standards for the way that
public enterprises report information about operating segments and requires
that those enterprises report selected information about operating segments in
interim financial reports issued to shareholders. In February 1998, the FASB
issued SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits". SFAS No. 132 revises employers' disclosures about
pension and other postretirement benefits plans. It does not change the
measurement or recognition of those plans. It standardizes the disclosure
requirements for pensions and other postretirements benefits to the extent
practicable, requires additional information on changes in the benefit
obligations and fair values of plan assets that will facilitate financial
analysis, and eliminates certain disclosures that are no longer as useful as
they were when SFAS No. 87 "Employers' Accounting for Pensions", SFAS No. 88
"Employers' Accounting for Settlements and Curtailments of Defined Benefit
Plans and for Termination Benefits" and SFAS No. 106 "Employers Accounting for
Postretirement Benefits Other Than Pensions" were issued. SFAS 132 suggests
combined formats for presentation of pension and other postretirement benefits
disclosures. The Company is currently evaluating the impact, if any, of SFAS
No. 131 and SFAS No. 132.

     In April 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of Position
98-5, "Reporting on the Costs of Start-Up Activities" ("SOP 98-5"), which
provides guidance on the financial reporting of start-up and organization
costs. It requires costs of start-up activities and organization costs to be
expensed as incurred. SOP 98-5 is effective for fiscal years beginning after
December 15, 1998. The Company is currently evaluating the impact, if any, of
SOP 98-5.

     In September 1998, the FASB issued SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS No. 133 establishes
accounting and reporting standards for derivative instruments, including
certain derivative instruments embedded in other contracts and for hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. The Company is currently evaluating the impact, if
any, of SFAS No. 133 which is effective for all quarters of fiscal years
beginning after June 15, 1999.


9. CONTINGENCIES

     Management is continually assessing the Company's obligations with respect
to applicable environmental protection laws. While it is difficult to determine
the timing and ultimate cost to be incurred by the Company in order to comply
with these laws, based upon available internal and external assessments with
respect to those environmental loss contingencies of which management of the
Company is aware, the Company believes that even without considering potential
insurance


                                      F-12
<PAGE>

                        L-3 COMMUNICATIONS CORPORATION

                   (COMBINED) FINANCIAL STATEMENTS--CONTINUED

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
recoveries, if any, there are no environmental loss contingencies that,
individually or in the aggregate, would be material to the Company's result of
operations. The Company accrues for these contingencies when it is probable
that a liability has been incurred and the amount of the loss can be reasonably
estimated.


     The Company is engaged in providing products and services under contracts
with the U.S. Government and to a lesser degree, under contracts with foreign
governments, some of which are funded by the U.S. Government. All such
contracts are subject to extensive legal and regulatory requirements, and,
periodically, agencies of the U.S. Government investigate whether such
contracts were and are being conducted in accordance with these requirements.
Under government procurement regulations, an indictment of the Company by a
Federal grand jury could result in the Company being suspended for a period of
time from eligibility for awards of new government contracts. A conviction
could result in debarment from contracting with the federal government for a
specified term.


     The Company is periodically subject to litigation, claims or assessments
and various contingent liabilities (including environmental matters) incidental
to its business. With respect to those investigative actions, items of
litigation, claims or assessments of which they are aware, management of the
Company believes that, after taking into account certain provisions that have
been made with respect to these matters, the ultimate resolution of any such
investigative actions, items of litigation, claims or assessments would not
have a material adverse effect on the financial position or result of
operations of the Company.


10. SUBSEQUENT EVENTS


   
     On November 12, 1998, L-3 Communications acquired all the outstanding
stock of DBS Microwave Inc. ("DBS") for $13,000 of cash subject to adjustment
based on closing net assets, as defined. The acquisition was financed with
borrowings under the Revolving Credit Facilities.
    


     On December 11, 1998, L-3 Communications completed the sale of $200,000 of
its 8% Senior Subordinated Notes due August 1, 2008 in a private placement
offering.


     On December 17, 1998, L-3 Communications acquired all of the outstanding
stock of Electrodynamics Inc. from Carpenter Technology Corporation for $21,500
in cash, subject to adjustment based on closing net assets, as defined. The
acquisition was financed with cash on hand and borrowings under the Senior
Credit Facilities.

To the Board of Directors of
 L-3 Communications Corporation


     We have audited the accompanying (i) consolidated balance sheet of L-3
Communications Corporation and subsidiaries (the "Company") as of December 31,
1997, and the related consolidated statements of operations, changes in
shareholders' equity, and cash flows for the nine months then ended, (ii)  the

These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. We did not audit the 1996 financial statements of the Lockheed
Martin Communications Systems Division, which statements reflect total assets
and sales constituting 35 percent and 30 percent of the related combined
totals. Those statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts included
for the Lockheed Martin Communications Systems Division for 1996, is based
solely on the report of the other auditors.


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


     In our opinion, the financial statements referred to above (i) present
fairly in all material respects the consolidated financial position of the
Company and subsidiaries as of December 31, 1997 and their consolidated results
of operations and cash flows for the nine months then ended, and (ii) based on
our audit and the report of other auditors for 1996, present fairly in all
material respects the combined financial position of the Predecessor Company as
of December 31, 1996 and their combined results of operations and cash flows
for the year then ended and the three months ended March 31, 1997, in
conformity with generally accepted accounting principles.

                         REPORT OF INDEPENDENT AUDITORS


Board of Directors
Lockheed Martin Corporation:


     We have audited the combined balance sheet of Lockheed Martin
Communications Systems Division, as defined in Note 1 to the financial
statements, as of December 31, 1996, and the related combined statements of
operations, changes in shareholders' equity and invested equity, and cash flows
for the two years in the period ended December 31, 1996. These financial
statements are the responsibility of the Division's and Lockheed Martin
Corporation's management. Our responsibility is to express an opinion on these
financial statements based on our audits.


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


     In our opinion, the combined financial statements referred to above
present fairly, in all material respects, the combined financial position of
Lockheed Martin Communications Systems Division at December 31, 1996 (not
presented separately herein), and the combined results of its operations and
its cash flows for the year ended December 31, 1996 (not presented separately
herein), and the results of its operations and its cash flows for the year
ended December 31, 1995, in conformity with generally accepted accounting
principles.

                        L-3 COMMUNICATIONS CORPORATION

             NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS

     The accompanying consolidated financial statements include the assets,
liabilities and results of operations of L-3 Communications Corporation,
successor company, ("L-3", "L-3 Communications" or the "Company"), a wholly
owned subsidiary of L-3 Communications Holdings, Inc. ("Holdings") following
the change in ownership (see Note 2) effective as of April 1, 1997 and for the
period from April 1, 1997 to December 31, 1997. Prior to April 1, 1997, the
statements comprise substantially all of the assets and liabilities and results
of operations of (i) nine business units previously purchased by Lockheed
Martin Corporation ("Lockheed Martin") as part of its acquisition of Loral
Corporation ("Loral") in April 1996 (the "Loral Acquired Businesses"), and (ii)
one business unit, Communications Systems -- East purchased by Lockheed Martin
as part of its acquisition of the aerospace business of GE in April 1993
(collectively, the "Businesses" or the "Predecessor Company"). The combined
financial statements of the Predecessor Company reflect the Businesses' assets,
liabilities and results of operations included in Lockheed Martin's historical
financial statements. Intercompany accounts between Lockheed Martin and the
Businesses have been included in Invested Equity. The assets and operations of
the semiconductor product line and certain other facilities which are not
material have been excluded from the combined financial statements. Significant
intercompany and inter-business transactions and balances have been eliminated.
 

     The Company is a wholly owned subsidiary of Holdings which owns all the
authorized, issued and outstanding common stock, par value $0.01 per share, of
the Company. Holdings has no other assets or liabilities and conducts no other
business other than through the Company. Certain obligations of the Company
have been fully, jointly and severally guaranteed by substantially all of its
subsidiaries. Non-guarantor subsidiaries are not significant to the
consolidated financial position and results of operations of the Company.

     The Company is a supplier of sophisticated secure communication systems
and specialized communication products including secure, high data rate
communication systems, microwave components, avionics, recorders, telemetry and
space products. The Company's customers include the Department of Defense (the
"DoD"), selected U.S. government intelligence agencies, major aerospace/defense
prime contractors and commercial customers. The Company operates primarily in
one industry segment, electronic components and systems.

     Substantially all the Company's products are sold to agencies of the U.S.
Government, primarily the DoD, to foreign government agencies or to prime
contractors or subcontractors thereof. All domestic government contracts and
subcontracts of the Businesses are subject to audit and various cost controls,
and include standard provisions for termination for the convenience of the U.S.
Government. Multi-year U.S. Government contracts and related orders are subject
to cancellation if funds for contract performance for any subsequent year
become unavailable. Foreign government contracts generally include comparable
provisions relating to termination for the convenience of the government.


2. CHANGE IN OWNERSHIP TRANSACTION

     Holdings was formed by Mr. Frank C. Lanza, the former President and Chief
Operating Officer of Loral, Mr. Robert V. LaPenta, the former Senior Vice
President and Controller of Loral (collectively, the "Equity Executives"),
Lehman Brothers Capital Partners III, L.P. and its affiliates (the "Lehman
Partnership") and Lockheed Martin to acquire the Businesses. On December 31,
1997, the Equity Executives, the Lehman Partnership and Lockheed Martin owned
approximately 14.9%, 50.1% and 34.0% of Holdings, respectively.

     On March 28, 1997, Lanza, LaPenta, the Lehman Partnership, L-3, and
Lockheed Martin entered into a Transaction Agreement (the "L-3 Acquisition
Agreement") whereby Holdings would acquire


                                      F-21
<PAGE>

                        L-3 COMMUNICATIONS CORPORATION

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
the Businesses from Lockheed Martin (the "L-3 Acquisition"). Also included in
the acquisition is a semiconductor product line of another business and certain
leasehold improvements in New York City which were not material. Pursuant to
the L-3 Acquisition Agreement, L-3 acquired the Businesses from Lockheed Martin
for $525,000, comprising $458,779 of cash, after a $21,221 reduction related to
a purchase price adjustment, and $45,000 of common equity, representing a 34.9%
interest in Holdings retained by Lockheed Martin, plus acquisition costs of
$8,000.

     The Company and Lockheed Martin finalized the purchase price adjustment
pursuant to an amendment to the L-3 Acquisition Agreement dated November 5,
1997, which also included the assumption by the Company of Lockheed Martin's
rights and obligations under a contract for the U.S. Army's Command and Control
Vehicle ("C2V") Mission Module Systems ("MMS"), for the production of mission
communication systems for track vehicles, for which the Company received a cash
payment of $12,176.

     In connection with the L-3 Acquisition Agreement, the Company anticipated
entering into a transition services agreement with Lockheed Martin pursuant to
which Lockheed Martin would provide to L-3 and its subsidiaries (and L-3 would
provide to Lockheed Martin) certain corporate services of a type previously
provided at costs consistent with past practices until December 31, 1997 (or,
in the case of Communications Systems -- East (formerly known as Communications
Systems -- Camden), for a period of up to 18 months after the Closing).
Lockheed Martin is providing L-3 the services contemplated by the proposed
transaction services agreement in the absence of any executed agreement. The
parties also entered into supply agreements which reflect previously existing
inter-company work transfer agreements or similar support arrangements upon
prices and other terms consistent with previously existing arrangements.
Holdings, the Company and Lockheed Martin have entered into certain subleases
of real property and cross-licenses of intellectual property.

     Pursuant to the L-3 Acquisition Agreement the Company also assumed certain
obligations relating to environmental liabilities and benefit plans.

     In accordance with Accounting Principles Board Opinion No. 16, the
acquisition of the Businesses by Holdings and L-3 has been accounted for as a
purchase business combination effective as of April 1, 1997. The purchase cost
(including the fees and expenses related thereto) was allocated to the tangible
and intangible assets and liabilities of the Company based upon their
respective fair values. The assets and liabilities recorded in connection with
the purchase price allocation were $664,800 and $164,400, respectively. The
excess of the purchase price over the fair value of net assets acquired of
$303,200 was recorded as goodwill, and is being amortized on a straight-line
basis over a period of 40 years. As a result of the 34.9% ownership interest
retained by Lockheed Martin, the provisions of Emerging Issues Task Force Issue
Number 88-16 were applied in connection with the purchase price allocation,
which resulted in the recognition of a deemed distribution of $9,000.

     In connection with the determination of the fair value of assets acquired
and pursuant to the provisions of Accounting Principles Board Opinion No. 16,
the Company has valued acquired contracts in process at contract price, less
the estimated cost to complete and an allowance for the Company's normal profit
on its effort to complete such contracts.

     Had the L-3 Acquisition occurred on January 1, 1996, the unaudited pro
forma sales and net income for the years ended December 31, 1997 and 1996 would
have been $703,600 and $11,890 and $663,200 and $5,290, respectively. The pro
forma results, which are based on various assumptions, are not necessarily
indicative of what would have occurred had the acquisition been consummated on
January 1, 1996. The 1997 and 1996 pro forma sales and net income data have
been adjusted to (i) include the operations of the Loral Acquired Businesses
from January 1, 1996 (Note 4) and (ii) exclude the operations of the Hycor
business net assets held for sale from January 1, 1996 (Note 6).

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     CASH AND CASH EQUIVALENTS: Cash equivalents consist of highly liquid
investments with a maturity of three months or less at time of purchase.

     STATEMENTS OF CASH FLOWS: Changes in operating assets and liabilities are
net of the impact of acquisitions and final purchase price allocations. The
Predecessor Company participated in Lockheed Martin's cash management system,
under which all cash was received and payments were made by Lockheed Martin.
All transactions between the Predecessor Company and Lockheed Martin have been
accounted for as settled in cash at the time the transactions were recorded by
the Predecessor Company.

     REVENUE RECOGNITION: Sales on production-type contracts are recorded as
units are shipped; profits applicable to such shipments are recorded pro rata,
based upon estimated total profit at completion of the contract. Sales and
profits on cost reimbursable contracts are recognized as costs are incurred.
Sales and estimated profits under other long-term contracts are recognized
under the percentage of completion method of accounting using the cost-to-cost
method. Amounts representing contract change orders or claims are included in
sales only when they can be reliably estimated and their realization is
probable.

     Losses on contracts are recognized when determined. Revisions in profit
estimates are reflected in the period, on a cumulative catch-up basis, in which
the facts, requiring the revision, become known.

     CONTRACTS IN PROCESS: Costs accumulated on contracts in process include
direct costs, as well as manufacturing overhead, and for government contracts,
general and administrative costs, independent research and development costs
and bid and proposal costs. In accordance with industry practice, contracts in
process contain amounts relating to contracts and programs with long
performance cycles, a portion of which may not be realized within one year.

     PROPERTY, PLANT AND EQUIPMENT:  Property, plant and equipment are stated
at cost. Depreciation is provided primarily on the straight-line method over
the estimated useful lives of the related assets. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life of
the improvements.

     COST IN EXCESS OF NET ASSETS ACQUIRED: The excess of the cost of the L-3
Acquisition over the fair value of the net assets acquired is being amortized
using a straight-line method over a 40 year period. Accumulated amortization of
the Company amounted to $5,741 at December 31, 1997.

     The carrying amount of cost in excess of net assets acquired is evaluated
on a recurring basis. Current and future profitability as well as current and
future undiscounted cash flows, excluding financing costs, of the acquired
businesses are primary indicators of recoverability. For the nine months ended
December 31, 1997, there was no reduction to the carrying amount of the cost in
excess of net assets acquired resulting from these evaluations.

     PREDECESSOR COMPANY INTANGIBLES: Intangibles, primarily the excess of the
cost of Businesses over the fair value of the net assets acquired, was
amortized using a straight-line method primarily over a 40-year period. Other
intangibles were amortized over their estimated useful lives which range from
11 to 15 years. Amortization expense of the Businesses was $2,655 for the three
months ended March 31, 1997; $10,115 and $6,086 for the years ended December
31, 1996 and 1995, respectively. Accumulated amortization was $26,524 at
December 31, 1996.

     Intangibles of the Predecessor Company include costs allocated to the
Businesses relating to the Request for Funding Authorization ("RFA"),
consisting of over 20 restructuring projects to reduce operating costs,
initiated by General Electric ("GE") Aerospace in 1990 and to the REC Advance


                                      F-23

                        L-3 COMMUNICATIONS CORPORATION

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
Agreement ("RAA"), a restructuring plan initiated after Lockheed Martin's
acquisition of GE Aerospace. The RAA was initiated to close two regional
electronic manufacturing centers. Restructure costs are reimbursable from the
U.S. Government if savings can be demonstrated to exceed costs. The total cost
of restructuring under the RFA and the RAA represented approximately 15% of the
estimated savings to the U.S. Government and, therefore, a deferred asset has
been recorded by Lockheed Martin. The deferred asset is being allocated to all
the former GE Aerospace sites, including the Communications Systems Division,
on a basis that includes manufacturing labor, overhead, and direct material
less non-hardware subcontracts. At December 31, 1997 and 1996, approximately
$2,313 and $4,400, respectively, of unamortized RFA and RAA costs are deferred
on the Company's and the Predecessor Company's consolidated (combined) balance
sheets in other current assets and other assets.

     The carrying values of the Predecessor Company intangibles were reviewed
if the facts and circumstances indicated potential impairment of their carrying
value. If this review indicated that intangible assets were not recoverable, as
determined based on the undiscounted cash flows of the entity acquired over the
remaining amortization period, the Businesses carrying values related to the
intangible assets were reduced by the estimated shortfall of cash flows.

     INCOME TAXES: The Company provides for income taxes using the liability
method prescribed by the Financial Accounting Standards Board ("FASB")
Statement No. 109, "Accounting for Income Taxes." Under the liability method,
deferred income tax assets and liabilities reflect tax carryforwards and the
net tax effects of temporary differences between the carrying amounts of assets
and liabilities for financial reporting and income tax purposes, as determined
under enacted tax laws and rates. The financial effect of changes in tax laws
or rates is accounted for in the period of enactment.

     PREDECESSOR COMPANY INCOME TAXES: The Predecessor Company was included in
the consolidated Federal income tax return and certain combined and separate
state and local income tax returns of Lockheed Martin. However, for purposes of
these financial statements, the provision for income taxes has been allocated
to the Predecessor Company based upon reported combined income before income
taxes. Income taxes, current and deferred, are considered to have been paid or
charged to Lockheed Martin and are recorded through the invested equity account
with Lockheed Martin. The principal components of the deferred taxes are
contract accounting methods, property, plant and equipment, goodwill
amortization and timing of accruals.

     RESEARCH AND DEVELOPMENT: Research and development costs sponsored by the
Company and the Predecessor Company include research and development, bid and
proposal costs related to government products and services. These costs
generally are allocated among all contracts and programs in progress under U.S.
Government contractual arrangements. Customer-sponsored research and
development costs incurred pursuant to contracts are accounted for as direct
contract costs.

     STOCK OPTIONS: In accordance with Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations, compensation expense for stock options is recognized in income
based on the excess, if any, of Holdings' fair value of the stock at the grant
date of the award or other measurement date over the amount an employee must
pay to acquire the stock. The exercise price for stock options granted to
employees equals or exceeds the fair value of the Holdings common stock at the
date of grant, thereby resulting in no recognition of compensation expense by
the Company. The Company has adopted the disclosure -- only provisions of SFAS
No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123").

     DERIVATIVE FINANCIAL INSTRUMENTS: In the normal course of financing
operations, the Company enters into interest rate cap and floor transactions
for interest rate protection purposes, and not for speculative or trading
purposes. Cash payments to and from the Company and the counterparties are
recorded as a component of interest expense. The initial cost of these
arrangements are deferred and amortized as interest expense.

     USE OF ESTIMATES: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses
during the reporting period. The most significant of these estimates and
assumptions relate to contract estimates of sales and costs, allocations from
Lockheed Martin, recoverability of recorded amounts of fixed assets and cost in
excess of net assets acquired, litigation and environmental obligations. Actual
results could differ from these estimates.

     EARNINGS PER SHARE: Earnings per share data is not presented since the
Company and the Predecessor company are wholly owned subsidiaries.

     ACCOUNTING PRONOUNCEMENTS: In June 1997, the FASB issued Statement of
Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
Income" and SFAS No. 131, "Disclosure about Segments of an Enterprise and
Related Information". SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components (revenues, expenses, gains
and losses) in full set general purpose financial statements. SFAS No. 131
establishes accounting standards for the way that public business enterprises
report selected information about operating segments and requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. In February 1998, the FASB issued
SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits". SFAS No. 132 revises employers' disclosures about pension and other
postretirement benefits plans. It does not change the measurement or
recognition of those plans. It standardizes the disclosure requirements for
pensions and other postretirement benefits to the extent practicable, requires
additional information on changes in the benefit obligations and fair values of
plan assets that will facilitate financial analysis, and eliminates certain
disclosures that are no longer as useful as they were when SFAS No. 87
"Employers' Accounting for Pensions", SFAS No. 88 "Employers' Accounting for
Settlements and Curtailments of Defined Benefit Pension Plans and for
Termination Benefits", and SFAS No. 106 "Employers' Accounting for
Postretirement Benefits Other Than Pensions", were issued. SFAS No. 132
suggests combined formats for presentation of pension and other postretirement
benefit disclosures. SFAS No. 130, SFAS No. 131 and SFAS No. 132 are required
to be adopted by 1998. The Company is currently evaluating the impact, if any,
of SFAS No. 130, SFAS No. 131 and SFAS No. 132.

     Effective January 1, 1996, the Businesses adopted SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets To Be
Disposed Of" ("SFAS 121"). SFAS 121 establishes the accounting standards for
the impairment of long-lived assets, certain intangible assets and cost in
excess of net assets acquired to be held and used for long-lived assets and
certain intangible assets to be disposed of. The impact of adopting SFAS 121
was not material.

     Effective in December 1997 the Company adopted the provisions of SFAS No.
128, "Earnings Per Share" ("SFAS 128") and No. 129, "Disclosure of Information
About Capital Structure" ("SFAS 129").

     RECLASSIFICATIONS:  Certain reclassifications have been made to conform
prior-year amounts to the current-year presentation.


4. PREDECESSOR COMPANY ACQUISITION

     Effective April 1, 1996, Lockheed Martin acquired substantially all the
assets and liabilities of the defense businesses of Loral, including the
Wideband Systems Division and the Products Group which are included in the
Businesses. The acquisition of the Wideband Systems Division and Products Group
businesses (the "Loral Acquired Businesses") has been accounted for as a
purchase by Lockheed

Martin Communications Systems -- Camden Division ("Division"). The acquisition
has been reflected in the financial statements based on the purchase price
allocated to those acquired businesses by Lockheed Martin. The assets and
liabilities recorded in connection with the purchase price allocation were
$401,000 and $113,200, respectively. As such, the accompanying combined
financial statements for periods prior to April 1, 1997 reflect the results of
operations of the Division and the Loral Acquired Businesses from the effective
date of acquisition including the effects of an allocated portion of cost in
excess of net assets acquired resulting from the acquisition.

6. NET ASSETS HELD FOR SALE

     The Company has accounted for the allocation of purchase price and the net
assets of its Hycor business in accordance with the FASB's Emerging Issues Task
Force Issue 87-11 "Allocation of Purchase Price to Assets to be Sold" ("EITF
87-11"). Accordingly, the net assets related to the Hycor business as of April
1, 1997 are included in the accompanying consolidated balance sheet as "Net
assets held for sale". The fair value assigned to such net assets is based upon
management's estimate of the proceeds from the sale of the Hycor business less
the estimated income from operations for such business during the holding
period of April 1, 1997 through January 29, 1998 (the "holding

period"), plus interest expense on debt allocated to such net assets during the
holding period. On January 29, 1998, the Company sold the Hycor business,
excluding land and buildings for $3,500 in cash subject to adjustment based on
final closing net assets. In accordance with EITF 87-11, loss from the
operations of the Hycor business of $108 and interest expense of $552 on the
debt allocated to the Hycor net assets have been excluded from the Company's
consolidated statements of operations for the nine months ended December 31,
1997. Management of the Company expects that any gain or loss realized on the
ultimate disposition of the Hycor business will not have a material impact on
the original purchase price allocation.

     Also included in net assets held for sale at December 31, 1997 is a
Company property located in Atlanta, Georgia.

</TABLE>

     In connection with the L-3 Acquisition, the Company entered into a credit
facility (the "Senior Credit Facilities") with a syndicate of banks and
financial institutions for $275,000 consisting of $175,000 of term loans (the
"Term Loan Facilities") and a $100,000 revolving credit facility (the
"Revolving Credit Facility"). The Senior Credit Facilities bear interest, at
the option of the Company, at rates related to (i) the higher of federal funds
rate plus 0.50% per annum or the reference rate published by Bank of America
NT&SA or (ii) LIBOR. At December 31, 1997, such interest rates, based on
various maturities, ranged from 7.625% to 8.625%. Interest payments vary in
accordance with the type of borrowing and are made at a minimum every three
months. The Revolving Credit Facility expires in 2003 and is available for
ongoing working capital and letter of credit needs. The Term Loans mature in
installments until the final maturity date in 2006. Approximately $93,428 of
the Revolving Credit Facility is available at December 31, 1997 reflecting
letters of credit of $6,572 drawn

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
against the Revolving Credit Facility of $100,000. In February 1998, the Senior
Credit Facilities were amended to, among other things, increase the Revolving
Credit Facility to $200,000, waive certain excess cash flow prepayments, as
defined, otherwise required, and permit the incurrence of up to an additional
$150,000 of subordinated debt. The Company pays a commitment fee of 0.375% per
annum on the unused portion of the Revolving Credit Facility.

     In April 1997, the Company issued $225,000 of 10 3/8% senior subordinated
notes (the "1997 Notes") due May 1, 2007 with interest payable semi-annually on
May 1 and November 1 of each year, commencing November 1, 1997. On November 5,
1997, the Company completed its exchange offer relating to the 1997 Notes and
the holders of the 1997 Notes received registered securities. The 1997 Notes
are redeemable at the option of the Company, in whole or in part, at any time
on or after May 1, 2002, at various redemption prices plus accrued and unpaid
interest to the applicable redemption date. In addition, prior to May 1, 2000,
the Company may redeem up to 35% of the aggregate principal amount of 1997
Notes at a redemption price of 109.375% of the principal amount thereof, plus
accrued and unpaid interest to the redemption date with the net cash proceeds
of one or more equity offerings by Holdings that are contributed to the Company
as common equity capital.

     The Senior Credit Facilities and the 1997 Notes agreement contain
financial and restrictive covenants that limit, among other things, the ability
of the Company to borrow additional funds, dispose of assets, or pay cash
dividends. At December 31, 1997, none of the Company's retained earnings were
available to pay dividends. The Senior Credit Facilities contain financial
covenants, which remain in effect so long as any amount is owed by the Company
thereunder. These financial covenants require that (i) the Company's debt
ratio, as defined, be less than or equal to 5.50 for the quarter ended December
31, 1997, and that the maximum allowable debt ratio, as defined, thereafter be
further reduced to less than or equal to 3.1 for the quarters ending after June
30, 2002, and (ii) the Company's interest coverage ratio, as defined, be at
least 1.85 for the quarter ended December 31, 1997, and thereafter increasing
the interest coverage ratio, as defined, to at least 3.10 for any fiscal
quarters ended after June 30, 2002. At December 31, 1997, the Company was in
compliance with these covenants.

     In connection with the Senior Credit Facilities, the Company has granted
the lenders a first priority lien on substantially all of the Company's assets,
including the stock of L-3 Communications Corporation.

     The aggregate principal payments for debt, excluding borrowings under the
Revolving Credit Facility, for the five years ending December 31, 1998 through
2002 are: $5,000, $11,000, $19,000, $25,000 and $33,200, respectively.

     The costs related to the issuance of debt have been deferred and are being
amortized as interest expense over the term of the related debt using a method
that approximates the effective interest method.



9. PREDECESSOR COMPANY'S INTEREST EXPENSE

     Interest expense has been allocated to the Predecessor Company by applying
Lockheed Martin's weighted average consolidated interest rate to the portion of
the beginning of the period invested equity account deemed to be financed by
consolidated debt, which has been determined based on Lockheed Martin's debt to
equity ratio on such date, except that the acquisition of the Loral Acquired
Businesses has been assumed to be fully financed by debt. Management of the
Businesses believes that this allocation methodology is reasonable.

10. FINANCIAL INSTRUMENTS

     The Company's financial instruments consist primarily of cash and cash
equivalents, billed contract receivables, other billed receivables (principally
commercial and affiliates), trade accounts payable, customer advances, debt
instruments, and interest rate cap and interest rate floor contracts. The book
values of cash and cash equivalents, billed contract receivables, other billed
receivables (principally commercial and affiliates), trade accounts payable and
customer advances are considered to be representative of their respective fair
values at December 31, 1997 due to the short-term maturities or expected
settlement dates of these instruments.

     The Company's debt instruments consist of term loans and 1997 Notes (Note
8). The carrying values of the term loans approximate fair value because they
are variable-rate loans which bear interest at current market rates.

     The 1997 Notes are registered, unlisted public debt which is traded in the
over-the-counter market. The fair value of such debt at December 31, 1997 was
estimated to be approximately $243,000, based on trading activity on December
31, 1997.

     To mitigate risks associated with changing interest rates on certain of
its debt, the Company entered into the interest rate agreements. The fair
values of the interest rate caps and interest rate floors (collectively, the
"interest rate agreements") were estimated by discounting expected cash flows
using quoted market interest rates. The Company manages exposure to
counterparty credit risk by entering into the interest rate agreements only
with major financial institutions that are expected to fully perform under the
terms of such agreements. The notional amounts are used to measure the volume
of these agreements and do not represent exposure to credit loss. The impact of
the interest rate agreements was not material to interest expense for the nine
months ended December 31, 1997. Information with respect to the interest rate
agreements is as follows:

</TABLE>

     At December 31, 1996, the Predecessor Company's financial instruments
consisted primarily of billed contract receivables, other billed receivables
(principally commercial and affiliates), trade accounts payable and customer
advances. The book value of billed contract receivables, other billed
receivables (principally commercial and affiliates), trade accounts payable and
customer advances approximated their respective fair values at December 31,
1996, due to the short-term maturities or expected settlement dates of those
instruments.

11. NONCASH COMPENSATION CHARGE

     Holdings' Class A Common Stock and Class B Common Stock were issued at per
share prices of $6.47 and $5.00, respectively. The aggregate difference in
issuance prices of $4,410 has been accounted for as a noncash compensation
charge to expense effective on April 1, 1997, related to the initial
capitalization of L-3.

     At December 31, 1997, the Company had $2,969 of tax credit carryforwards,
primarily related to U.S. federal net operating losses and research and
experimentation tax credits which expire, if unused, in 2012. The Company
believes that these carryforwards will be available to reduce future income tax
liabilities and has recorded these carryforwards as non-current deferred tax
assets.


PREDECESSOR COMPANY

     The (benefit) provision for income taxes for the Predecessor Company was
calculated by applying statutory tax rates to the reported income (loss) before
income taxes after considering items that do not enter into the determination
of taxable income and tax credits reflected in the consolidated provision of
Lockheed Martin, which are related to the Businesses. Substantially all the
income of the Businesses are from domestic operations. For the three months
ended March 31, 1997, it is estimated that the benefit for deferred taxes
represents $1,315. For the years ended December 31, 1996 and 1995, it is
estimated that the (benefit) provision for deferred taxes represents ($2,143)
and $3,994, respectively.

     The effective income tax rate of the Predecessor Company differs from the
statutory Federal income tax rate for the following reasons:

13. STOCK OPTIONS

THE COMPANY

     Holdings sponsors an option plan for key employees of the Company,
pursuant to which options to purchase up to 3,255,815 shares of Holdings common
stock have been authorized for grant.

     On April 30, 1997, Holdings adopted the 1997 Option Plan for key employees
and granted to the Equity Executives nonqualified options to purchase, at $6.47
per share, 2,285,714 shares of Class A common stock of Holdings. In each case,
half of the options are "Time Options" and half are "Performance Options"
(collectively, the "Options"). The Time Options become exercisable with respect
to 20% of the shares subject to the Time Options on each of the first five
anniversaries if employment continues through and including such date. The
Performance Options become exercisable nine years after the grant date, but may
become exercisable earlier with respect to up to 20% of the shares subject to
the Performance Options on each of the first five anniversaries, to the extent
certain defined targets are achieved. The Options, which have a ten year term,
become fully exercisable under certain circumstances, including a change in
control.

     On July 1, 1997 and November 11, 1997, Holdings granted nonqualified
options to certain officers and other employees of Holdings to purchase at
$6.47 per share 689,500 shares of Class A common

stock of Holdings (collectively, the "1997 Options"). Generally, the 1997
Options vest over a three-year period and expire ten years from the date of
grant.

     The exercise price for Holdings' stock options granted to employees in
1997 equaled the estimated fair value of Holdings' common stock at the date of
grant. Accordingly, in accordance with APB 25, no compensation expense was
recognized by Holdings.

     Pro forma information regarding net earnings as required by SFAS 123 has
been determined as if Holdings had accounted for its employee stock options
under the fair value method. Because Holdings is a nonpublic entity the fair
value for the options was estimated at the date of grant using the minimum
value method prescribed in SFAS 123, which does not consider the expected
volatility of Holdings' stock price, with the following weighted-average
assumptions for 1997: risk-free interest rate of 6.3%; dividend yield of 0%;
and weighted-average expected option life of 5.49 years.

     For purposes of pro forma disclosures, the compensation cost of the
options based on their estimated fair values is amortized to expense over
vesting periods of the options. The Company's net income for the nine months
ended December 31, 1997 would have decreased to the pro forma amounts indicated
below:

</TABLE>

     The weighted-average grant-date fair value of options granted during the
nine months ended December 31, 1997 was $1.82 per option. The weighted average
remaining contract life of the Company outstanding stock options was 9.37 years
at December 31, 1997.


PREDECESSOR COMPANY

     During the three months ended March 31, 1997 and the years ended December
31, 1996 and 1995, certain employees of the Predecessor Company participated in
Lockheed Martin's stock option plans. All stock options granted had 10 year
terms and vested over a two year service period. Exercise prices of options
awarded in both years were equal to the market price of the stock on the date
of grant. Pro forma information regarding net earnings (loss) as required by
SFAS No. 123 has been determined as if the Predecessor Company had accounted
for its employee stock options under the fair value method. The fair value for
these options was estimated at the date of grant using a Black-Scholes option
pricing model with the following weighted-average assumptions for the three
months ended March 31, 1997, and the years ended December 31, 1996 and 1995,
respectively: risk-free interest rates of 5.58%, 5.58% and 6.64%; dividend
yield of 1.70%; volatility factors related to

the expected market price of the Lockheed Martin's common stock of .186, .186
and .216; weighted-average expected option life of five years. The
weighted-average fair values of options granted during 1997, 1996 and 1995 were
$17.24, $17.24 and $16.09, respectively.

     For the purposes of pro forma disclosures, the options' estimated fair
values are amortized to expense over the options' vesting periods. The
Predecessor Company's pro forma net loss for the three months ended March 31,
1997 and the years ended December 31, 1996 and 1995 were ($386), $11,531, and
($1,040), respectively.

     Real estate lease commitments have been reduced by minimum sublease
rentals of $22,106 due in the future under noncancellable subleases.

     Leases covering major items of real estate and equipment contain renewal
and or purchase options which may be exercised by the Company and Predecessor
Company. Rent expense, net of sublease income from other Lockheed Martin
entities was $7,330 for the Company for the nine months ended December 31,
1997; $2,553 for the Predecessor Company for the three months ended March 31,
1997 and $8,495 and $4,772 for the Predecessor Company for the years ended
December 31, 1996 and 1995, respectively.

     The Company is and the Predecessor Company has been engaged in providing
products and services under contracts with the U.S. Government and to a lesser
degree, under foreign government contracts, some of which are funded by the
U.S. Government. All such contracts are subject to extensive legal and
regulatory requirements, and, from time to time, agencies of the U.S.
Government investigate whether such contracts were and are being conducted in
accordance with these requirements. Under government procurement regulations,
an indictment of the Company and the Predecessor Company by a federal grand
jury could result in the Company and the Predecessor Company being suspended
for a period of time from eligibility for awards of new government contracts. A
conviction could result in debarment from contracting with the federal
government for a specified term.

     The decline in the U.S. defense budget since the mid-1980s has resulted in
program delays, cancellations and scope reduction for defense contracts in
general. These events may or may not have an effect on the Company's programs;
however, in the event that U.S. Government expenditures for products of the
type manufactured by the Company are reduced, and not offset by greater
commercial sales or other new programs or products, or acquisitions, there may
be a reduction in the volume of contracts or subcontracts awarded to the
Company.

     Pursuant to the L-3 Acquisition Agreement, Holdings and the Company has
agreed to assume certain on-site and off-site environmental liabilities related
to events or activities occurring prior to the consummation of the L-3
Acquisition. Lockheed Martin has agreed to retain all environmental liabilities
for all facilities not used by the Businesses as of April 1997 and to indemnify
fully Holdings for such prior site environmental liabilities. Lockheed Martin
has also agreed, for the first eight years following April 1997 to pay 50% of
all costs incurred by Holdings above those reserved for on the Company's
balance sheet at March 31, 1997 relating to certain Company-assumed
environmental liabilities and, for the seven years thereafter, to pay 40% of
certain reasonable operation and maintenance costs relating to any
environmental remediation projects undertaken in the first eight years. The
Company believes that its total liability for known or reasonably probable
environmental claims, even without consideration of the Lockheed Martin
indemnification, would not either individually or collectively have a material
adverse effect upon Holdings' financial condition or upon the results of its
operations.

     Management continually assesses the Company's obligations with respect to
applicable environmental protection laws. While it is difficult to determine
the timing and ultimate cost to be incurred by the Company in order to comply
with these laws, based upon available internal and external assessments, with
respect to those environmental loss contingencies of which management is aware,
the Company believes that even without considering potential insurance
recoveries, if any, there are no environmental loss contingencies that,
individually or in the aggregate, would be material to the Company's results of
operations. The Company accrues for these contingencies when it is probable
that a liability has been incurred and the amount of the loss can be reasonably
estimated.

     The Company and the Predecessor Company have been periodically subject to
litigation, claims or assessments and various contingent liabilities (including
environmental matters) incidental to its business. With respect to those
investigative actions, items of litigation, claims or assessments of which they
are aware, management of the Company is of the opinion that the probability is
remote that, after taking into account certain provisions that have been made
with respect to these matters, the ultimate resolution of any such
investigative actions, items of litigation, claims or assessments will have a
material adverse effect on the financial position or results of operations of
the Company and the Predecessor Company.


15. PENSIONS AND OTHER EMPLOYEE BENEFITS


THE COMPANY

     PENSIONS: The Company maintains a number of pension plans, both
contributory and noncontributory, covering certain employees. Eligibility for
participation in these plans varies and benefits are generally based on
members' compensation and years of service. The Company's funding policy is
generally to contribute in accordance with cost accounting standards that
affect government contractors, subject to the Internal Revenue Code and
regulations thereon. Plan assets are invested primarily in U.S. government and
agency obligations and listed stocks and bonds.

     Pension expense for the nine months ended December 31, 1997 includes the
following components:

</TABLE>

     The following assumptions were used in accounting for pension plans for
the Company:

   Rate of return on plan assets .............       9.00%               9.00%
</TABLE>

     In connection with the Company's assumption of certain plan obligations
pursuant to the L-3 Acquisition, Lockheed Martin has provided the PBGC with
commitments to assume sponsorship or other forms of financial support under
certain circumstances. In this connection, the Company has provided certain
assurances to Lockheed Martin including, but not limited to, (i) continuing to
fund the pension plans consistent with prior practices and to the extent
deductible for tax purposes and, where appropriate, recoverable under
Government contracts, (ii) agreeing to not increase benefits under the pension
plans without the consent of Lockheed Martin, (iii) restricting the Company
from a sale of any businesses employing individuals covered by the pension
plans if such sale would not result in reduction or elimination of the Lockheed
Martin Commitment with regard to the specific plan and (iv) if the pension
plans were returned to Lockheed Martin, granting Lockheed Martin the right to
seek recovery from the Company of those amounts actually paid, if any, by
Lockheed Martin with regard to the pension plans after their return.

     POST-RETIREMENT HEALTH CARE AND LIFE INSURANCE: In addition to providing
pension benefits, the Company provides certain health care and life insurance
benefits for retired employees and dependents at certain locations.
Participants are eligible for these benefits when they retire from active
service and meet the eligibility requirements for the Company's pension plans.
These benefits are funded primarily on a pay-as-you-go basis with the retiree
generally paying a portion of the cost through contributions, deductibles and
coinsurance provisions.

     Post-retirement health care and life insurance costs for the nine months
ended December 31, 1997 include the following components:

</TABLE>

     Actuarial assumptions used in determining the December 31, 1997
accumulated post-retirement benefit obligation include a discount rate of
7.25%, an average rate of compensation increase of 5.0% and an assumed health
care cost trend rate of 6.5% in 1997 decreasing gradually to a rate of 4.5% by
the year 2001. The discount rate used at April 1, 1997 was 7.50%. The other
assumptions did not change from April 1, 1997. Increasing the assumed health
care cost trend rate by 1% would change the accumulated post-retirement
benefits obligation at December 31, 1997 by approximately $2,218 and the
aggregate service and interest cost components for the nine months ended
December 31, 1997 by approximately $81 and $113, respectively.

     EMPLOYEE SAVINGS PLAN: Under its various employee savings plans, the
Company matches the contributions of participating employees up to a designated
level. The extent of the match, vesting terms and the form of the matching
contribution vary among the plans. Under these plans, the Company's matching
contributions, in cash, for the nine months ended December 31, 1997 was $3,742.
 


THE PREDECESSOR COMPANY

     Certain of the Businesses for the Predecessor Company participated in
various Lockheed Martin-sponsored pension plans covering certain employees.
Eligibility for participation in these plans varies, and benefits are generally
based on members' compensation and years of service. Lockheed Martin's funding
policy was generally to contribute in accordance with cost accounting standards
that affect government contractors, subject to the Internal Revenue Code and
regulations. Since the aforementioned pension arrangements are part of certain
Lockheed Martin defined benefit plans, no separate actuarial data is available
for the portion allocable to the Businesses. Therefore, no liabilities or
assets are reflected in the accompanying combined financial statements of the
Predecessor Company as of December 31, 1996. The Businesses have been allocated
pension costs based upon participant employee headcount. Net pension expense
included in the accompanying combined financial statements of the Predecessor
Company was $1,848 for the three months ended March 31, 1997, and $7,027 and
$4,134, for the years ended December 31, 1996 and 1995, respectively.

     In addition to participating in Lockheed Martin-sponsored pension plans,
certain of the Businesses of the Predecessor Company provided varying levels of
health care and life insurance benefits for retired employees and dependents.
Participants were eligible for these benefits when they retired from active
service and met the pension plan eligibility requirements. These benefits are
funded primarily on a pay-as-you-go basis with the retiree generally paying a
portion of the cost through contributions, deductibles and coinsurance
provisions. Since the aforementioned postretirement benefits are part of
certain Lockheed Martin postretirement arrangements, no separate actuarial data
is available for the portion allocable to the Businesses. Accordingly, no
liability is reflected in the accompanying combined financial statements as of
combined December 31, 1996 and 1995. The Businesses have been allocated
postretirement benefits cost based on participant employee

headcount. Postretirement benefit costs included in the accompanying combined
financial statements was $616 for the three months ended March 31, 1997 and
$2,787 and $2,124 for the years ended December 31, 1996 and 1995, respectively.
Under various employee savings plans sponsored by Lockheed Martin, the
Predecessor Company matched contributions of participating employees up to a
designated level. Under these plans the matching contributions for the three
months ended March 31, 1997 and for the years ended December 31, 1996 and 1995
were $1,241, $3,940 and $1,478, respectively.

18. OTHER TRANSACTIONS WITH LOCKHEED MARTIN

     The Company and the Predecessor Company sell products to Lockheed Martin
and its affiliates, net sales for which were $60,402 for the nine months ended
December 31, 1997; $21,171 for the three months ended March 31, 1997 and
$70,658 and $25,874 for the years ended December 31, 1996 and 1995,
respectively. Included in Contracts in Process are receivables from Lockheed
Martin and its affiliates of $8,846 and $10,924 at December 31, 1997 and 1996,
respectively.

     Lockheed Martin provides the Company information systems and other
services and previously provided similar services to the Predecessor Company
for which the Company and the Predecessor Company were charged $13,690, $4,210,
$20,901 and $20,508 for the nine months ended December 31, 1997, the three
months ended March 31, 1997 and the years ended December 31, 1996 and 1995,
respectively.

expenses related to these services have been allocated to the Businesses, the
combined financial position, results of operations and cash flows presented in
the accompanying combined financial statements would not be the same had the
Businesses been independent entities.

     The amount of allocated corporate expenses to the Predecessor Company and
reflected in these combined financial statements was estimated based primarily
on an allocation methodology prescribed by government regulations pertaining to
government contractors. Allocated costs to the Businesses were $5,208 for the
three months ended March 31, 1997, and $10,057 and $2,964 for the years ended
December 31, 1996 and 1995, respectively.

                        REPORT OF INDEPENDENT AUDITORS

Board of Directors of
 L-3 Communications Corporation:


     We have audited the accompanying combined statements of operations and
cash flows for the Loral Acquired Businesses as defined in Note 1 (the
"Businesses") for the three months ended March 31, 1996 and the year ended
December 31, 1995. These financial statements are the responsibility of the
Businesses' management. Our responsibility is to express an opinion on these
financial statements based on our audits.


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


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined results of the operations and cash flows
of the Businesses for the three months ended March 31, 1996 and the year ended
December 31, 1995, in conformity with generally accepted accounting principles.

1. BACKGROUND AND DESCRIPTION OF BUSINESS

     On January 31, 1997, Lockheed Martin Corporation ("Lockheed Martin"),
Lehman Brothers Holdings Inc. ("Lehman"), Frank C. Lanza ("Lanza") and Robert
V. LaPenta ("LaPenta") entered into a Memorandum of Understanding ("MOU")
regarding the transfer of certain businesses of Lockheed Martin to a newly
formed corporation ("Newco") to be owned by Lockheed Martin, Lehman, Lanza and
LaPenta. The businesses proposed to be transferred (the "Loral Acquired
Businesses" or "Businesses") include Lockheed Martin's Wideband Systems
Division and the Products Group, comprised of ten autonomous operations, all of
which were acquired by Lockheed Martin effective April 1, 1996 as part of the
acquisition by Lockheed Martin of the defense electronics business of Loral
Corporation ("Loral"). Also included in the transaction is the acquisition of a
semiconductor product line of another business and certain leasehold
improvements in New York City.

     The Businesses are leading suppliers of sophisticated secure communication
systems, microwave communication components, avionic and instrumentation
products and other products and services to major aerospace and defense
contractors as well as the U.S. Government. The Businesses operate primarily in
one industry segment, communication systems and products.

     Substantially all the Businesses' products are sold to agencies of the
United States Government, primarily the Department of Defense, to foreign
government agencies or to prime contractors or subcontractors thereof. All
domestic government contracts and subcontracts of the Businesses are subject to
audit, various cost controls and include standard provisions for termination
for the convenience of the government. Multi-year government contracts and
related orders are subject to cancellation if funds for contract performance
for any subsequent year become unavailable. Foreign government contracts
generally include comparable provisions relating to termination for the
convenience of the government.

     The decline in the U.S. defense budget since the mid 1980s has resulted in
program delays, cancellations and scope reductions for defense contractors in
general. These events may or may not have an effect on the Businesses'
programs; however, in the event that expenditures for products of the type
manufactured by the Businesses are reduced, and not offset by greater foreign
sales or other new programs or products, or acquisitions, there may be a
reduction in the volume of contracts or subcontracts awarded to the Businesses.
 

     The Businesses' operations, as presented herein, include allocations and
estimates of certain expenses of Loral based upon estimates of services
performed by Loral that management of the Businesses believe are reasonable.
Such services include treasury, cash management, employee benefits, taxes, risk
management, internal audit and general corporate services. Accordingly, the
results of operations and cash flows as presented herein may not be the same as
would have occurred had the Businesses been independent entities.


2. BASIS OF PRESENTATION


BASIS OF COMBINATION

     The accompanying combined financial statements reflect the Businesses'
assets, liabilities and operations included in Loral Corporation's historical
financial statements that will be transferred to Newco. All significant
intercompany transactions and amounts have been eliminated. The combined
financial statements do not include the operations of telecommunications switch
product line which will not be transferred and was exited in 1995. Also, the
assets and operations of the semiconductor product line and certain other
facilities which are not material to the Businesses have been excluded from the
financial statements.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
                            (DOLLARS IN THOUSANDS)
 
ALLOCATION OF CORPORATE EXPENSES

     The amount of corporate office expenses reflected in these financial
statements has been estimated based primarily on the allocation methodology
prescribed by government regulations pertaining to government contractors,
which management of the Businesses believes to be a reasonable allocation
method.


INCOME TAXES

     The Businesses were included in the consolidated Federal income tax return
and certain combined and separate state and local income tax returns of Loral.
However, for the purposes of these financial statements, the provision for
income taxes was allocated based upon reported income before income taxes. Such
provision was recorded through the advances from (repayments to) Loral account.
 


INTEREST EXPENSE

     Interest expense has been allocated to the Businesses by applying Loral's
weighted average consolidated interest rate to the portion of the beginning of
the period invested equity account deemed to be financed by consolidated debt,
which amount has been determined based on Loral's debt to equity ratio on such
date, except that the acquisition of Wideband Systems has been assumed to be
fully financed by debt.


STATEMENTS OF CASH FLOWS

     The Businesses participated in Loral's cash management system, under which
all cash was received and payments made by Loral. All transactions between the
Businesses and Loral have been accounted for as settled in cash on the date
such transactions were recorded by the Businesses.


3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


CONTRACTS IN PROCESS

     Sales on long-term production-type contracts are recorded as units are
shipped; profits applicable to such shipments are recorded pro rata, based upon
estimated total profit at completion of the contract. Sales and profits on cost
reimbursable contracts are recognized as costs are incurred. Sales and
estimated profits under other long-term contracts are recognized under the
percentage of completion method of accounting using the cost-to-cost method.
Amounts representing contract change orders or claims are included in sales
only when they can be reliably estimated and realization is probable. Incentive
fees and award fees enter into the determination of contract profits when they
can be reliably estimated.

     Costs accumulated under long-term contracts include direct costs as well
as manufacturing, overhead, and for government contracts, general and
administrative, independent research and development and bid and proposal
costs. Losses on contracts are recognized when determined. Revisions in profit
estimates are reflected in the period in which the facts which require the
revision become known.


DEPRECIATION AND AMORTIZATION

     Depreciation is provided primarily on the straight-line method over the
estimated useful lives of the related assets. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life of
the improvements. The excess of the cost of purchased businesses over the fair
value of the net assets acquired is being amortized using a straight-line
method generally over a 40-year period.

<PAGE>

                           LORAL ACQUIRED BUSINESSES

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
                            (DOLLARS IN THOUSANDS)
 
     The carrying amount of cost in excess of net assets acquired is evaluated
on a recurring basis. Current and future profitability as well as current and
future undiscounted cash flows, excluding financing costs, of the underlying
businesses are primary indicators of recoverability. There were no adjustments
to the carrying amount of cost in excess of net assets acquired resulting from
these evaluations during the periods presented.


USE OF ESTIMATES


     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Businesses' management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses
during the reporting period. The most significant of these estimates and
assumptions relate to contract estimates of sales and costs, cost allocations
from Loral, including interest and income taxes, recoverability of recorded
amounts of fixed assets and cost in excess of net assets acquired, litigation
and environmental obligations. Actual results could differ from these
estimates.


NEW ACCOUNTING PRONOUNCEMENTS


     Effective January 1, 1996, the Businesses adopted Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets to Be Disposed Of" ("SFAS 121"). SFAS 121 establishes the accounting
standards for the impairment of long-lived assets, certain intangible assets
and cost in excess of net assets and certain intangible assets to be disposed
of. The impact of adopting SFAS 121 was not material.


     Effective January 1, 1994, the Businesses adopted Statement of Financial
Accounting Standards No. 112, "Employers' Accounting for Postemployment
Benefits" ("SFAS 112"). SFAS 112 requires that the costs of benefits provided
to employees after employment but before retirement be recognized on an accrual
basis. The adoption of SFAS 112 did not have a material impact on the results
of operations of the Businesses.


4. ACQUISITIONS


     Effective May 1, 1995, Loral acquired substantially all the assets and
liabilities of the Defense Systems operations of Unisys Corporation, which
included the Wideband Systems Division. The acquisition has been accounted for
as a purchase. As such, the accompanying combined financial statements reflect
the results of operations of the Wideband Systems Division from the effective
date of acquisition, including the amortization of an allocated portion of cost
in excess of net assets acquired resulting from the acquisition. Such
allocation was based on the sales and profitability of the Wideband Systems
Divisions relative to the aggregate sales and profitability of the defense
systems operations acquired by Loral. The assets and liabilities recorded in
connection with the purchase price allocation were $240,525 and $25,598,
respectively.


     Had the acquisition of the Wideband Systems Division occurred on January
1, 1995, the unaudited pro forma sales and net income for the year ended
December 31, 1995 would have been $524,355 and $504,780, respectively. The
results, which are based on various assumptions, are not necessarily indicative
of what would have occurred had the acquisition been consummated as of January
1, 1995.

6. INCOME TAXES


     The provision for income taxes was calculated by applying Loral's
statutory tax rates to the reported pre-tax book income after considering items
that do not enter into the determination of taxable income and tax credits
reflected in the consolidated provision which are related to the Businesses. It
is estimated that deferred income taxes represent approximately $714,000 and
$2,857,000 of the provisions for income taxes reflected in these financial
statements for the three months ended March 31, 1996 and the year ended
December 31, 1995. The principal components of deferred income taxes are
contract accounting methods, property plant and equipment, goodwill
amortization, and timing of accruals. Substantially all of the Businesses'
income is from domestic operations.


     The following is a reconciliation of the statutory rate to the effective
tax rates reflected in the financial statements:

8. COMMITMENTS AND CONTINGENCIES

     The Businesses lease certain facilities and equipment under agreements
expiring at various dates through 2011. Leases covering major items of real
estate and equipment contain renewal and/or purchase options which may be
exercised by the Businesses. Rent expense for the three months ended March 31,
1996 was $1,063. Rent expense for the year ended December 31, 1995 was $4,276.

     Management is continually assessing its obligations with respect to
applicable environmental protection laws. While it is difficult to determine
the timing and ultimate cost to be incurred by the Businesses in order to
comply with these laws, based upon available internal and external assessments,
the Businesses believe that even without considering potential insurance
recoveries, if any, there are no environmental loss contingencies that,
individually or in the aggregate, would be material to the Businesses'
operations. The Businesses accrue for these contingencies when it is probable
that a liability has been incurred and the amount of the loss can be reasonably
estimated. The Businesses believe that it has adequately accrued for future
expenditures in connection with environmental matters and that such
expenditures will not have a material adverse effect on its financial position
or results of operations.

     There are a number of lawsuits or claims pending against the Businesses
and incidental to its business. However, in the opinion of management, the
ultimate liability on these matters, if any, will not have a material adverse
effect on the financial position or results of operations of the Businesses.


9. PENSIONS AND OTHER EMPLOYEE BENEFITS


PENSIONS

     The Businesses participate in various Loral-sponsored pension plans both
contributory and non-contributory covering certain employees. Eligibility for
participation in these plans varies, and benefits are generally based on
members' compensation and years of service. Loral's funding policy was
generally to contribute in accordance with cost accounting standards that
affect government contractors, subject to the Internal Revenue code and
regulations thereon. Since the aforementioned pension arrangements were part of
certain Loral defined benefit or defined contribution plans, no separate
actuarial data was available for the Businesses. The Businesses have been
allocated their share of pension costs based upon participation employee
headcount. Net pension expense, which approximates the amount funded, included
in the accompanying financial statements was $1,234 and $4,391 for the three
months ended March 31, 1996 and the year ended December 31, 1995, respectively.
 


POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS

     In addition to participating in Loral-sponsored pension plans, the
Businesses provide certain health care and life insurance benefits for retired
employees and dependents at certain locations. Participants are eligible for
these benefits when they retire from active service and meet the pension plan
eligibility requirements. These benefits are funded primarily on a
pay-as-you-go basis with the retiree generally paying a portion of the cost
through contributions, deductibles and coinsurance provisions. Since the
aforementioned postretirement benefits were part of certain Loral
postretirement arrangements, no separate actuarial data is available for the
Businesses. The Businesses have been allocated postretirement benefit costs
based upon participant employee headcount. Post-retirement benefits costs
included in the accompanying financial statements were $402 and $1,646 for the
three months ended March 31, 1996 and the year ended December 31, 1995,
respectively.

EMPLOYEE SAVINGS PLANS


     Under various employee savings plans sponsored by Loral, the Businesses
matched the contributions of participating employees up to a designated level.
The extent of the match, vesting terms and the form of the matching
contribution vary among the plans. Under these plans, the matching
contributions, in cash, common stock or both, for the three months ended March
31, 1996 and the year ended December 31, 1995 were $634 and $1,879,
respectively.


10. SALES TO PRINCIPAL CUSTOMERS


     The Businesses operate primarily in one industry segment, electronic
components and systems. Sales to principal customers are as follows:

11. RELATED PARTY TRANSACTIONS


     The Businesses had a number of transactions with Loral and its affiliates.
Management believes that the arrangements are as favorable to the Businesses as
could be obtained from unaffiliated parties. The following describe the related
party transactions.


     Loral allocated certain operational, administrative, legal and other
services to the Businesses. Costs allocated to the Businesses were $1,827 and
$6,535 for the three months ended March 31, 1996 and the year ended December
31, 1995, respectively. The Businesses sold products to Loral and its
affiliates. Net sales to Loral were $14,840 for the three months ended March
31, 1996 and were $54,600 in 1995. Net sales to Space Systems/Loral were $2,471
for the three months ended March 31, 1996 and were $4,596 in 1995. Net sales to
K&F Industries were $1,173 for the three months ended March 31, 1996 and were

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     SPD Technologies Inc. ("SPD") and Subsidiaries (the "Company") develop,
manufacture and market electrical power delivery systems and components and
vehicular control systems, focused on switching and distribution and frequency
and voltage conversion for military, commercial marine, rail transportation,
utility and commercial specialty markets in the United States and overseas.
SPD's products encompass the entire electrical distribution (power delivery)
system utilized on self-contained power systems such as ships and rail cars.

     In January 1997, SPD Holdings Inc., a company formed by an investor group
and certain minority stockholders of SPD Technologies Inc., the predecessor
company, acquired all of the outstanding stock of the Company. The acquisition
was accounted for as a purchase and was financed by the issuance of common and
preferred stock and bank borrowings. As a result of certain minority
shareholders of the predecessor company acquiring ownership in SPD Holdings
Inc., the Company recorded a carryover basis adjustment to stockholders' equity
of $(2,151,000). During 1997, SPD Holdings Inc. changed its name to SPD
Technologies Inc.

     The accompanying unaudited condensed financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the

accruals) considered necessary for a fair presentation have been included.

Board of Directors
SPD Technologies Inc.:


     We have audited the accompanying consolidated balance sheet of SPD
Technologies Inc. and Subsidiaries as of December 31, 1997, and the related
consolidated statements of earnings and cash flows for the year then ended.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audit.


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


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of SPD
Technologies Inc. and Subsidiaries as of December 31, 1997, and the
consolidated results of their operations and their consolidated cash flows for
the year then ended in conformity with generally accepted accounting

                    SPD TECHNOLOGIES INC. AND SUBSIDIARIES

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997


NOTE A--BUSINESS AND SUMMARY OF ACCOUNTING POLICIES

     SPD Technologies Inc. ("SPD") and Subsidiaries (the "Company") develop,
manufacture and market electrical power delivery systems and components and
vehicular control systems, focused on switching and distribution and frequency
and voltage conversion for military, commercial marine, rail transportation,
utility and commercial specialty markets in the United States and overseas.
SPD's products encompass the entire electrical distribution (power delivery)
system utilized on self-contained power systems such as ships and rail cars.

     In January 1997, SPD Holdings Inc., a company formed by an investor group
and certain minority stockholders of SPD Technologies Inc., the predecessor
company, acquired all of the outstanding stock of the Company. The acquisition
was accounted for as a purchase and was financed by the issuance of common and
preferred stock and bank borrowings. As a result of certain minority
shareholders of the predecessor company acquiring ownership in SPD Holdings
Inc., the Company recorded a carryover basis adjustment to stockholders' equity
of $(2,151,000). During 1997, SPD Holdings Inc. changed its name to SPD
Technologies Inc.

     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying consolidated financial statements follows:


1. PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of SPD and its
wholly-owned subsidiaries, SPD Electrical Systems, Inc., SPD Switchgear Inc.,
PacOrd Inc., Henschel, Inc., Power Paragon Inc. and its wholly-owned
subsidiaries. All material intercompany accounts and transactions have been
eliminated.


2. REVENUE RECOGNITION

     Revenues for production-type contracts are recognized as units are shipped
or are substantially ready to be shipped subject to customer inspection.
Revenues on long-term, production-type contracts, service contracts and
engineering and development contracts are recognized on the
percentage-of-completion method, whereunder the estimated sales value is
determined on the basis of contract milestones achieved and costs are
recognized on the basis of contract percentage completions (as measured by
applying the most recent estimated profit margin for the entire contract at
completion to the revenues recognized based on contractual milestones
achieved).

     The Company believes its approach is conservative and generally results in
lower revenues and gross profits in the early stages of a contract when
estimates are more susceptible to change.

     Sales under cost reimbursement contracts are recorded as costs are
incurred and include estimated earned fees proportionate to total estimated
costs. The fees under certain government contracts may be increased or
decreased in accordance with cost or performance incentive provisions, which
measure actual performance against established targets or other criteria. Such
incentive fee awards or penalties are included in sales at the time the amounts
can be reasonably determined.

     Generally, sales and earnings on long-term government contracts are
determined on a contract-by-contract basis, based on estimates that are
reviewed and revised periodically and adjustments to recognized sales and
earnings resulting from such revisions are recorded on a cumulative basis in
the period in which they are identified. Provisions for anticipated losses are
made in the period in which they first become determinable.

3. CASH AND CASH EQUIVALENTS

     The Company classifies all highly liquid investments with original
maturities of less than three months as cash equivalents.

NOTE A--BUSINESS AND SUMMARY OF ACCOUNTING POLICIES (CONTINUED)
 
4. INVENTORIES

     Inventories are stated at the lower of cost or market with appropriate
provision to reduce excess and obsolete inventory to net realizable values.
Generally, the Company values inventory at cost, which approximates actual on a
first-in, first-out basis and the weighted moving average method. One
subsidiary values inventory related to government contracts to include all
costs identified with the contract and an allocation of all other indirect
costs, including marketing, general and administrative, and other expenses.


5. PROPERTY, PLANT AND EQUIPMENT

     Depreciation and amortization of property, plant and equipment are
computed by the straight-line method over the estimated useful lives of the
assets for financial reporting purposes and straight-line and accelerated
methods for tax reporting purposes.


6. INTANGIBLE ASSETS

     Goodwill is being amortized on a straight-line basis over forty years.
Deferred financing costs are being amortized over the five-year term of the
loan agreement. The Company evaluates goodwill on an annual basis for possible
impairment based on the expected future cash flows of the businesses acquired.


7. INCOME TAXES

     Deferred income taxes arise from temporary differences between income tax
and financial reporting and principally relate to postretirement benefits other
than pensions, pension costs, depreciation, inventory and various accrued
expenses.


8. FOREIGN CURRENCY TRANSLATION

     The assets and liabilities of the Company's German subsidiaries are
translated into U.S. dollars at current exchange rates in effect at the
reporting date. Income statement items are generally translated at average
exchange rates prevailing during the year. The resulting translation
adjustments are recorded as a separate component of stockholders' equity. Gains
or losses resulting from foreign currency transactions are included in the
consolidated statement of earnings as incurred.


9. ACCOUNTING ESTIMATES

     In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure
of contingent assets and liabilities at the date of the financial statements
and revenues and expenses during the reporting period. Actual results could
differ from those estimates.


NOTE B--ACQUISITION OF POWER PARAGON INC.

     At the close of business on June 30, 1997, SPD acquired all of the
outstanding stock of Power Paragon Inc. ("PPI") and subsidiaries (formerly
known as PTS Holdings, Inc. and subsidiaries). PPI develops and manufactures
electrical power systems and components for military and commercial specialty
applications in the United States and overseas. The acquisition was financed
principally by bank borrowings. The acquisition has been accounted for as a
purchase and, accordingly, the results of

operations of PPI are included in the consolidated financial statements from
the date of acquisition. In lieu of cash, certain minority stockholders of PPI
exchanged options for the purchase of stock in PPI for options to purchase
shares of the Company's common stock. The fair value of the PPI options
exchanged, totalling approximately $2,324,000, was recorded as additional
paid-in capital at the date of the acquisition.

NOTE E--LONG-TERM DEBT (CONTINUED)
 
     Substantially all of the assets and capital stock of the Company's
subsidiaries are pledged as collateral for borrowings under the term and
revolving loans. The loan agreement limits the payment of dividends and
provides for mandatory prepayments based upon excess cash flow, as defined. The
agreement also contains various restrictive financial covenants including
interest coverage and leverage ratios and limitations on annual capital
expenditures. Commencing January 1, 1998, the Company has the option to elect a
fixed rate of interest based on LIBOR. At December 31, 1997, approximately
$16,000,000 is available on the revolving loan payable.

     The following is a summary of the annual maturities of long-term debt:

NOTE F--COMMITMENTS AND CONTINGENCIES

     The Company conducts a substantial portion of its business utilizing
leased facilities and equipment with terms lasting through June 2009. The terms
of one principal facility lease include an option to purchase the leased
premises based on 50% of the fair market value of the land and 100% of the fair
market value of the building. The Company can renew the lease for two
additional five-year terms.

     At December 31, 1997, future minimum payments under noncancellable
operating leases with remaining terms of more than one year were as follows:

     Rent expense for operating leases was approximately $3,344,000 for the
year ended December 31, 1997.

     As a defense contractor for the U.S. Government, the books, records and
other supporting documentation of the Company used to establish certain
contract prices are subject to audit to determine the allowability and
reasonableness of costs. The Company routinely undergoes audits by the
Government on both a pre-award and post-award basis.

NOTE F--COMMITMENTS AND CONTINGENCIES (CONTINUED)
 
     The Company contributed approximately $1,000 in 1997 to multiemployer
pension plans for employees covered by collective bargaining agreements. Under
the Multiemployer Pension Plan Amendments Act of 1980, if the plan terminates
or the Company withdraws, the Company could be subject to a "withdrawal
liability."


NOTE G--PREFERRED STOCK AND COMMON STOCK WARRANT AND OPTIONS

     The preferred stock has a stated value of $100 per share and provides for
cumulative dividends at 8%. All shares of preferred stock are subject to
mandatory redemption at the stated value in the event of a sale of securities
of the Company or a sale of substantially all of the assets or a significant
subsidiary of the Company.

     In connection with the acquisition discussed in Note A, the Company issued
a warrant for the purchase of 1,000 shares of common stock at an exercise price
of $1.00 to the principal stockholder of the Company. The warrant expires on
December 31, 2006.

     In connection with the acquisition discussed in Note B, the Company issued
options for the purchase of 4,397 shares of the Company's common stock at an
exercise price of $68.37 per share. The options are exercisable in four years
or if the Company is acquired. The Company issued additional options to acquire
an aggregate of 14,740 Class B Nonvoting common shares to employees and
directors. The options are exercisable at $1.00 per share and expire on July 1,
2007. These options become exercisable only upon the closing of an initial
public offering or a sale of the Company for an amount in excess of a "minimum
threshold amount." One-half of the options vest in 12 1/2% increments over the
initial four-year period. The remaining one-half of the options vest in four
equal installments beginning on December 31, 1998, based upon the attainment of
certain performance goals.

     The Company has determined that a compensation charge will be recorded
once it is determined that it is likely that the options will become
exercisable, as defined above. The amount of the compensation charge will be
based upon the difference between the fair value of the shares of the Company's
common stock at the date of exercise and the exercise price. No compensation
charge has been recorded as of December 31, 1997.

</TABLE>

     The weighted average discount rates used in determining the present value
of the projected benefit obligations was 8.15%. The projected rate of increase
in future compensation levels was 5% - 5.5%. The expected long-term rate of
return on assets was 8% - 9.5%. The Company's policy is to fund pension cost
under its pension plan to the extent necessary under the Employee Retirement
Income Security Act of 1974. For the year ended December 31, 1997, the Company
recorded actuarial and other gains on its pension plans totalling approximately
$3,239,000 principally resulting from better than projected performance of plan
assets.


2. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS


     Certain subsidiaries of the Company have a defined benefit postretirement
plan that provides medical benefits for retirees. The Company does not fund
retiree benefits in advance. In 1993, the predecessor company established plan
cost maximums to account for and control future medical costs more effectively.
The Company requires that the projected future cost of providing postretirement
benefits, principally health care, be accrued over the period earned rather
than expensed as claims are incurred.


     Net periodic postretirement benefit cost for the year ended December 31,
1997, included the following components:



<TABLE>

                                                                               ------------
   Net periodic postretirement benefit cost ...............................    $     91,000

</TABLE>

     Cost was determined by application of the terms of the medical plan,
including the effects of established maximums on covered costs, together with
relevant actuarial assumptions and health care cost trend rates projected at
annual rates progressively declining from 12% in 1995. Future benefits for
union-represented employees will be capped at the limits in effect for December
31, 1996. The effect of a 1% annual increase in these assumed cost trend rates
would increase the accumulated postretirement benefit obligation by
approximately $919,000 in 1997; the annual costs would not be materially
affected. For the year ended December 31, 1997, the Company recognized prior
service costs of approximately $4,362,000 relating to additional costs of
salaried employees whose employer contributions do not have a cap and
approximately $6,476,000 of net gains resulting from various underwriting
changes including lower expected medical cost premiums as a result of more
salaried employees choosing HMO's.

</TABLE>

     Measurement of the accumulated postretirement benefit obligation was based
on an assumed discount rate of 8.15% in 1997. The health care cost trend rate
for salaried employees was 9% in 1997.


3. EMPLOYEES' SAVINGS AND PROFIT-SHARING PLAN

     The Company maintains various employee 401(k) savings plans. The Company
contributes a guaranteed minimum of eligible employee contributions. Additional
company contributions are voluntary and at the discretion of the Board of
Directors. Profit-sharing expense was approximately $754,000 for the year ended
December 31, 1997.


4. SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

     The Company has two supplemental executive retirement plans which are
nonqualified plans maintained primarily for the purpose of providing additional
deferred compensation for a select group of management or highly compensated
employees, as defined by the Employee Retirement Income Security Act of 1974.
Participation in, benefits under, and the duration of the plans are subject to
the Company's discretion.

     Participants in the plans accrue benefits each fiscal year based on the
Company's discretionary contribution for each participant. The Company has
accrued $132,000 of estimated yearly contributions to be paid for the year
ended December 31, 1997.

     In conjunction with the establishment of the plans, the Company
established rabbi trusts to aid in the payment of plan benefits. The trusts are
revocable and the assets contributed to the trusts can only be used to pay
participant benefits, with certain exceptions. Although the rabbi trusts
established are revocable by the Company, the trust agreements provide that,
after a change in control, the rabbi trusts shall not be revocable until all
protected benefits have been paid in full. The assets held in the trusts at
December 31, 1997 (included in other assets) amounted to approximately
$576,000. Earnings on trust assets are allocated to participants' accounts and
are included in the trust assets amount.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



Board of Directors
SPD TECHNOLOGIES INC.:


     We have audited the accompanying consolidated balance sheets of SPD
Technologies Inc. and Subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of earnings and accumulated deficit and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.


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


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of SPD
Technologies Inc. and Subsidiaries as of December 31, 1996 and 1995, and the
consolidated results of their operations and their consolidated cash flows for
the years then ended in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          DECEMBER 31, 1996 AND 1995


NOTE A--BUSINESS AND SUMMARY OF ACCOUNTING POLICIES

     SPD Technologies, Inc. ("SPD") and Subsidiaries (the "Company") develop,
manufacture and service circuit protection systems, ship control systems and
combat systems, and perform overhaul and repairs for naval vessels primarily
under fixed-price contracts. At December 31, 1996, Merrill Lynch Capital Corp.
("MLCC") owned 77.9% of the Company. Reference is made to Note L.

     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying consolidated financial statements follows:


1. PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of SPD and its
wholly-owned subsidiaries, SPD Switchgear Inc., PacOrd Inc. and Henschel, Inc.
All material intercompany accounts and transactions have been eliminated. In
1996, the Company purchased the minority interest of Henschel, Inc. for
$21,912.


2. REVENUE RECOGNITION

     Substantially all of the Company's revenues and accounts receivable arise
from contracts with the U.S. Navy or its suppliers.

     Production-type contracts, not classified as long-term, provide a
substantial portion of the Company's revenues. Revenues are recognized as units
are shipped or are substantially ready to be shipped subject to customer
inspection. Revenues on long-term, production-type contracts, service contracts
and engineering and development contracts are recognized on the
percentage-of-completion method. Under the Company's methodology, revenues and
gross profit are recognized based on billings rather than on a level-of-effort
basis. The Company believes its approach is more conservative and generally
results in lower revenues and gross profits in the early stages of a contract
when estimates are more susceptible to change. Provisions for anticipated
losses are made in the period in which they first become determinable.


3. INVENTORIES

     Inventories are stated at the lower of cost or market, with appropriate
provision to reduce excess and obsolete inventory to net realizable values. In
general, cost is currently adjusted standard cost, which approximates actual
cost on a first-in, first-out basis, and the weighted moving average method.


4. EQUIPMENT AND LEASEHOLD IMPROVEMENTS

     Depreciation and amortization are computed by the straight-line method
over their estimated useful lives for financial reporting purposes and
straight-line and accelerated methods for tax reporting purposes.


5. INCOME TAXES

     Deferred income taxes arise from temporary differences between income tax
and financial reporting and principally relate to postretirement benefits other
than pensions, pension costs, depreciation, inventory and various accrued
expenses.


6. ACCOUNTING ESTIMATES

     In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure
of contingent assets and liabilities at the date of the financial statements
and revenues and expenses during the reporting period. Actual results could
differ from those estimates.

NOTE B--INVENTORIES

     Inventories primarily relate to production-type contracts and include
expenditures for materials, purchased parts and work-in-process beyond what is
required for recorded orders. These expenditures are incurred primarily to help
maintain stable production schedules.

     Inventories consist of the following:

NOTE D--REVOLVING CREDIT FACILITY

     During 1995, the Company entered into a $15,000,000 revolving credit
facility with a financial institution which expires on November 29, 1998.
Borrowings are based upon eligible accounts receivable and inventory of the
Company, as defined. Borrowings bear interest at the lender's prime rate plus
 .50% (9% at December 31, 1996).

     The agreement contains certain restrictive covenants, including, among
other matters, the requirement to maintain certain financial ratios, and
restricts the payment of dividends. Borrowings under this facility are
collateralized by the Company's inventories and accounts receivable. Available
borrowings under this credit arrangement are subject to a 0.37 percent
commitment fee.

</TABLE>

     Total rental expense for operating leases was approximately $1,875,000 and
$1,787,000 for the years ended December 31, 1996 and 1995, respectively.

     As a defense contractor for the U.S. Government, the books, records and
other supporting documentation of the Company used to establish certain
contract prices are subject to audit to determine the allowability and
reasonableness of costs. The Company routinely undergoes audits by the
Government on both a pre-award and post-award basis.


NOTE G--COMMON STOCK AND INCENTIVE STOCK OPTIONS

     In 1995, the Company sold 2,355 shares of common stock previously held in
treasury to two employees and a director.

     The Company has options outstanding to key executives for the purchase of
954 shares of common stock at an exercise price of $1.00 per share. The options
expire on December 31, 2002.

     The weighted average discount rates used in determining the present value
of the projected benefit obligations was 8.15% in 1996 and 1995. The projected
rate of increase in future compensation levels was 5.0% for both years. The
expected long-term rate of return on assets was 9.5% for both years. Prior
service costs are amortized using a straight-line method over the average
remaining service period of employees expected to receive benefits under the
plan. The Company's policy is to fund pension cost under its pension plan to
the extent necessary under the Employee Retirement Income Security Act of 1974.
 


2. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

     The Company has a defined benefit postretirement plan that provides
medical benefits for retirees. The Company does not fund retiree benefits in
advance. In 1992, the Company established plan cost maximums to account for and
control future medical costs more effectively. The Company requires that the
projected future cost of providing postretirement benefits, principally health
care, be accrued over the period earned rather than expensed as claims are
incurred.

     Net periodic postretirement benefit cost for the years ended December 31,
1996 and 1995, included the following components:

     Cost was determined by application of the terms of the medical plan,
including the effects of established maximums on covered costs, together with
relevant actuarial assumptions and health care cost trend rates projected at
annual rates progressively declining from 12% in 1995. Future benefits will be
capped at the limits in effect for December 31, 1996. The effect of a 1% annual
increase in these assumed cost trend rates would increase the accumulated
postretirement benefit obligation by approximately $-0- in 1996 and $32,000 in
1995; the annual costs would not be materially affected. In addition to net
periodic postretirement cost, the Company recognized an actuarial gain of
$3,000 in 1995.

     The following tables provide information on the status of the plan at
December 31, 1996 and 1995.

     Measurement of the accumulated postretirement benefit obligation was based
on an assumed discount rate of 8.15% in 1996 and 1995. The health care cost
trend rate was 0% in 1996 and 12% in 1995.


3. EMPLOYEES' SAVINGS AND PROFIT-SHARING PLAN

     The Company maintains an hourly and salaried employees' savings plan. The
Company contributes a guaranteed minimum of eligible employee contributions.
Additional company contributions of up to 25% of eligible employee
contributions are voluntary and at the discretion of the Board of Directors.
Profit-sharing expense was approximately $642,000 and $506,000 for the years
ended December 31, 1996 and 1995, respectively.


4. MULTIEMPLOYER PLAN

     The Company contributed $1,000 in 1996 and 1995 to multiemployer pension
plans for employees covered by collective bargaining agreements. These plans
are not administered by the Company and contributions are determined in
accordance with provisions of the negotiated labor contract. Information with
respect to the Company's proportionate share of the excess, if any, of the
actuarially computed value of vested benefits over the total of the pension
plans' net assets is not available from the plans' administrators.

                           CALIFORNIA MICROWAVE, INC.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

                  SIX MONTHS ENDED DECEMBER 31, 1996 AND 1997


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


BASIS OF PRESENTATION


     The accompanying unaudited financial statements include the operations of
the Satellite Transmission Systems Division ("STS" or the "Division") of
California Microwave, Inc. ("CMI" or the "Company"). The Division is a global
satellite communication systems integrator providing hardware, software and
services for turnkey projects to large commercial customers, principally
domestic and foreign telephone companies and major common carriers and to the
U.S. and foreign governments.


     These financial statements are presented as if the Division had existed as
an entity separate from CMI during the periods presented and include the
historical assets, liabilities, sales and expenses that are directly related to
the Division's operations. However, these financial statements are not
necessarily indicative of the financial position and results of operations
which would have occurred had the Division been an independent entity.


     The accompanying unaudited condensed financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the six-month periods ended December 31, 1996 and 1997
are not necessarily indicative of the results that may be expected for the
years ended June 30, 1997 and 1998. For further information, refer to the
financial statements and footnotes thereto included in the Division's financial
statements for the year ended June 30, 1997.


USE OF ESTIMATES; RISKS AND UNCERTAINTIES


     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Significant estimates are used in determining the
collectibility of accounts receivable, warranty costs, inventory realization,
profitability on long-term contracts, restructuring reserves, recoverability of
property, plant and equipment, and contingencies. Actual results could differ
from estimates.


INVENTORIES AND COST OF PRODUCTS SOLD


     Inventories are recorded at the lower of cost or market. Project
inventories are transferred to cost of products sold at the time revenue is
recognized based on the estimated total manufacturing costs and total contract
prices under each contract. Losses on contracts are recognized in full when the
losses become determinable. The cost of other inventories is generally based on
standard costs which approximate actual costs determined by the first-in,
first-out method.

3. CORPORATE ALLOCATIONS


     CMI allocates corporate expenses on a value-added basis to each division,
which CMI believes results in a reasonable allocation of such costs. The
accompanying financial statements reflect charges for general corporate
administrative expenses incurred by CMI which amounted to approximately
$832,000 and $793,000 for the six months ended December 31, 1996 and 1997,
respectively.


     No interest is allocated by CMI to the Division.


     The Division is charged for its proportional share of CMI's self-insured
medical plan. Such charges amounted to $1,015,000 and $732,000 for the six
months ended December 31, 1996 and 1997, respectively.


     In addition, there were direct charges from CMI as follows:

</TABLE>

     The Division believes that the direct charges from CMI were reasonable
during the periods presented.


4. RESTRUCTURING


     During fiscal 1997, a comprehensive review of the Division's operations
was performed, including a review of inventory levels, product development and
migration plans and facility and personnel needs. It was determined to focus
the Division on potentially higher margin products. This resulted in the
write-down of certain inventories and the restructuring of the Division's
operations. During the six month period ended December 31, 1996 inventory and
other charges of $10,300,000, arising from this review, were included in cost
of products sold. During February 1997, additional charges of $800,000 relating
to excess facilities and severance were recorded. There are no remaining cash
outlays associated with the restructuring at December 31, 1997.

5. OTHER


     In November 1997, the Division recorded a $1 million charge to cost of
sales relating to a contract with a customer in Sudan. The President of the
United States imposed economic sanctions on Sudan which banned U.S. companies
from doing business in Sudan and as a result, the Division could not continue
to perform under the existing contract. Based upon this, the contract was
terminated and the Division has been released from further performance
requirements.


     On December 19, 1997, L-3 Communications Corporation, an unrelated party,
reached an agreement to purchase from CMI substantially all of the assets of
the Division, and to assume certain of the liabilities of the Division, for
approximately $27 million in cash. The final purchase price is subject to
adjustment based on the net assets of the Division at the closing date of the
transaction.

                         REPORT OF INDEPENDENT AUDITORS


The Board of Directors
California Microwave, Inc.


     We have audited the accompanying balance sheets of the Satellite
Transmission Systems Division of California Microwave, Inc. (the "Company") as
of June 30, 1997 and 1996, and the related statements of operations and cash
flows for each of the three years in the period ended June 30, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.


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


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Satellite Transmission
Systems Division of California Microwave, Inc., as of June 30, 1997 and 1996,
and the results of its operations and its cash flows for each of the three
years in the period ended June 30, 1997 in conformity with generally accepted
accounting principles.

                  SATELLITE TRANSMISSION SYSTEMS DIVISION OF
                           CALIFORNIA MICROWAVE, INC.

                         NOTES TO FINANCIAL STATEMENTS

                    YEARS ENDED JUNE 30, 1995, 1996 AND 1997


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


BASIS OF PRESENTATION

     The accompanying financial statements include the operations of the
Satellite Transmission Systems Division ("STS" or the "Division") of California
Microwave, Inc. ("CMI" or the "Company"). The Division is a global satellite
communication systems integrator providing hardware, software and services for
turnkey projects to large commercial customers, principally domestic and
foreign telephone companies and major common carriers and to the U.S. and
foreign governments.

     These financial statements are presented as if the Division had existed as
an entity separate from CMI during the periods presented and include the
historical assets, liabilities, sales and expenses that are directly related to
the Division's operations. However, these financial statements are not
necessarily indicative of the financial position and results of operations
which would have occurred had the Division been an independent entity.


USE OF ESTIMATES; RISKS AND UNCERTAINTIES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Significant estimates are used in determining the
collectibility of accounts receivable, warranty costs, inventory realization,
profitability on long-term contracts, restructuring reserves, recoverability of
property, plant and equipment, and contingencies. Actual results could differ
from estimates.


CASH AND CASH EQUIVALENTS

     The Division participates in CMI's centralized cash management function;
accordingly, the Division does not maintain separate cash accounts, other than
payroll and foreign subsidiary accounts, which are deemed insignificant, and
its cash disbursements and collections are settled through Division equity.


INVENTORIES AND COST OF PRODUCTS SOLD

     Inventories are recorded at the lower of cost or market. Project
inventories are transferred to cost of products sold at the time revenue is
recognized based on the estimated total manufacturing costs and total contract
prices under each contract. Losses on contracts are recognized in full when the
losses become determinable. During the year ended June 30, 1995, the Division
recognized losses of approximately $2,800,000 on such contracts. The cost of
other inventories is generally based on standard costs which approximate actual
costs determined by the first-in, first-out method.


PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are carried at cost, less accumulated
depreciation and amortization. Depreciation and amortization charges are
computed using the straight-line method based on the estimated useful lives of
the related assets.


INTANGIBLE ASSETS OF BUSINESS ACQUIRED

     During 1997, CMI wrote off $1,888,000 of purchased intangible assets,
principally goodwill, relating to the original acquisition of STS by CMI, which
was pushed down to the Division's books.

                  SATELLITE TRANSMISSION SYSTEMS DIVISION OF
                           CALIFORNIA MICROWAVE, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
The intangible assets consisted of the excess of the purchase price paid for
STS over the net tangible assets acquired and was amortized using the
straight-line method over 30 years. During 1997, CMI determined that the excess
purchase price was not recoverable due to a significant reduction in sales by
the Division in 1997 as compared to prior periods and appropriately reduced the
carrying value.


OTHER LONG-LIVED ASSETS

     In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed of," the Division records impairment losses on long-lived assets
used in operations when events and circumstances indicate that the assets might
be impaired and the undiscounted cash flows estimated to be generated by those
assets are less than the carrying amount of such assets. Other than as
described above related to purchased intangibles, no such losses have been
incurred.


REVENUE RECOGNITION, RECEIVABLES AND CREDIT RISK

     Revenue from product sales is recognized at the time of shipment. Sales on
certain long-term, small quantity, high unit value contracts are recognized at
the completion of significant project milestones, which are generally contract
line items. Scheduled billings and retainages under certain contracts
(principally export contracts) have deferred billing provisions resulting in
unbilled accounts receivable (included in accounts receivable) of $7,426,000
and $4,425,000 at June 30, 1996 and 1997, respectively. The unbilled receivable
at June 30, 1997, is expected to be collected within one year.

     The Division manufactures and sells satellite communications products,
systems and turnkey telecommunications networks to large commercial customers,
principally domestic and foreign telephone companies and major common carriers,
and to the U.S. government. The Division generally requires no collateral, but
generally requires letters of credit, denominated in U.S. dollars, from its
foreign customers.

     During 1996 and 1997, the Division periodically transferred certain
international accounts receivable to CMI. CMI insures these receivables under a
credit insurance program and then sells the receivables, without recourse, at
prevailing discount rates. The Division retains the responsibility to collect
and service these amounts. Outstanding customer receivables transferred to CMI
through Division equity amounted to approximately $421,000 and $2,100,000
during 1996 and 1997, respectively.

     The Division charged to operations $150,000, $100,000 and $750,000 for its
provision for doubtful accounts in 1995, 1996 and 1997, respectively.


WARRANTY

     The Company generally warrants its products for a period of 12 to 24
months from completion of contract or shipment. Warranty expense was
approximately $679,000, $753,000 and $688,000 for 1995, 1996 and 1997,
respectively.


INCOME TAXES

     Income taxes reflect an allocation of CMI's income tax expense (benefit)
calculated based on CMI's effective tax rate. All deferred tax assets and
liabilities relating to the Division are included in intercompany balances with
CMI and are accounted for within Division equity (see Note 7). On a

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
stand-alone basis, income tax benefit (expense) for the year ended June 30,
1997 would not be material due to the existence of net operating loss
carryforwards at the Division level and the need for a full valuation allowance
on any resulting net deferred tax asset. Such net operating losses have been
fully utilized by CMI.


FISCAL YEAR

     The Division's fiscal year ends on the Saturday closest to June 30, and
includes 52 weeks in fiscal 1995, 1996 and 1997. For 1995, 1996 and 1997, the
fiscal years ended on July 1, 1995, June 29, 1996 and June 28, 1997,
respectively. For clarity of presentation, the financial statements are
reported as ending on a calendar month end.

</TABLE>

     The Division believes that the direct charges from CMI were reasonable
during the periods presented.


11. RELATED PARTY TRANSACTIONS

     Included in net sales are product sales to other divisions of CMI. These
sales totaled $3,584,000, $640,000 and $1,800,000 for 1995, 1996 and 1997,
respectively. In addition, there is approximately $2,363,000, $2,937,000 and
$776,000 of purchases from another division of CMI which is included in ending
inventory and $2,139,000, $3,576,000 and $1,129,000 due to this division which
is included in accounts payable at June 30, 1995, 1996 and 1997, respectively.


12. RESTRUCTURING

     In June 1995, a decision was made to close the Division's Melbourne,
Florida facility as well as to perform a review of personnel needs at the
Division's operations. Pursuant to these decisions, approximately $2.4 million
of restructuring charges were recorded, including approximately $600,000 to
reflect the facility at its net realizable value. There are no remaining cash
outlays associated with the restructuring at June 30, 1997.

     In December 1996 and January 1997, a comprehensive review of the
Division's operations was performed, including a review of inventory levels,
product development and migration plans and facility and personnel needs. It
was determined to focus the Division on potentially higher margin products.
This resulted in the write-down of certain inventories and the restructuring of
the Division's operations. Inventory and other charges of $10,300,000, arising
from this review, were included in cost of products sold and excess facilities
and severance charges of $800,000 were included in restructuring. There are no
remaining cash outlays associated with the restructuring at June 30, 1997.


13. SUBSEQUENT EVENTS

     In November 1997, the Division recorded a $1 million charge to cost of
sales relating to a contract with a customer in Sudan. The President of the
United States imposed economic sanctions on Sudan which banned U.S. companies
from doing business in Sudan, and as a result the Division could not continue
to perform under the existing contract. Based upon this, the contract was
terminated and the Division has been released from further performance
requirements.

     On December 19, 1997, L-3 Communications Corporation, an unrelated party,
reached an agreement to purchase from CMI substantially all of the assets of
the Division, and to assume certain of the liabilities of the Division, for
approximately $27 million in cash. The final purchase price is subject to
adjustment based on the net assets of the Division at the closing date of the
transaction.

                       ILEX SYSTEMS, INC. AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997


(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

     ILEX Systems, Inc. (the "Company") provides services and products
primarily in four areas: environmental consulting services to private and
public sector customers; software consulting services to the federal government
and its contractors; supervisory control and data acquisition products and
services to the electrical utility industry; and secured communications
products, principally to the federal government and its agencies. The majority
of the Company's revenues are derived from its software consulting services.


PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the financial
statements of the Company and its wholly owned subsidiary. All significant
intercompany balances and transactions have been eliminated in consolidation.


REVENUE RECOGNITION

     The Company's consulting services are generally performed on time- and
materials-based contracts for the federal government and its contractors.
Accordingly, revenues are recognized as services are performed. Equipment sales
revenues are recognized upon shipment. Unbilled accounts receivable comprise
charges for services and materials provided to customers that have not been
invoiced.

     The Company does not require collateral for its receivables. Reserves are
maintained for potential credit losses.


CASH EQUIVALENTS

     Cash equivalents of $1,879,285 as of December 31, 1997, consist
principally of money market investments. For purposes of the accompanying
consolidated statement of cash flows, the Company considers all highly liquid
debt instruments with remaining maturities of three months or less when
acquired to be cash equivalents.


FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying value of financial instruments in the Company's consolidated
financial statements approximates fair value due to the short-term maturities
of these instruments.


INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out basis) or
market.


PROPERTY, PLANT, AND EQUIPMENT

     Property, plant, and equipment are stated at cost. Depreciation is
calculated using the straight-line method over the estimated useful lives of
the assets (generally five years). Leasehold improvements are amortized
straight-line over the shorter of the lease term or the estimated useful life
of the asset.


GOODWILL

     Goodwill, which represents the excess of purchase price over the fair
value of net assets acquired, is amortized on a straight-line basis over the
expected periods to be benefited of 10 to 15 years. The Company assesses the
recoverability of goodwill by determining whether the amortization of the
goodwill balance over its remaining life can be recovered through undiscounted
future operating cash flows of the acquired operation.


                                     F-103

INCOME TAXES

     The Company elected S corporation status on March 17, 1997, effective
January 1, 1997. Federal and the majority of state income taxes on the income
of S corporations are generally payable by the individual shareholders rather
than the Company.

     Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.


USE OF ESTIMATES

     The Company's management has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these consolidated financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.


(2) INVENTORIES

     Inventories consisted of the following as of December 31, 1997:

                                                         ========
</TABLE>

(3) LINE OF CREDIT AND LONG-TERM DEBT

     The Company has a $5,000,000 line of credit with a bank that is due on
demand. Interest is payable at the bank's prime rate (8.5% as of December 31,
1997) and is secured by trade accounts receivable, inventories, and other
assets. Borrowings outstanding under the line of credit were $-0- as of
December 31, 1997. The line of credit contains certain restrictive financial
covenants, including a minimum level of net worth and cash flow to debt ratio.
As of December 31, 1997, the Company was in compliance with all such covenants.
 

     The Company has an unsecured promissory note payable to a former
shareholder that was issued in conjunction with the repurchase of shares of
common stock in 1992. The note bears interest at 10% with payments of $6,000
per month, including interest, through December 1998. As of December 31, 1997,
the principal balance of this note was $62,833.


(4) INCOME TAXES

     The provision for income taxes for the year ended December 31, 1997,
consisted of the following:

</TABLE>

                                     F-104
<PAGE>

     The provision for income taxes for the year ended December 31, 1997,
differs from the federal statutory rate, primarily due to the flow through
nature of income tax liability to the shareholders and reduction of the federal
and partial state deferred income tax assets and liabilities as of December 31,
1996, resulting from the S corporation election as follows:



<TABLE>
<CAPTION>
<S>                                                               <C>
            Federal income tax statutory rate .................       34.0%
            State income tax rate .............................        2.2
            Benefit of federal S corporation election .........      (28.8)
                                                                     -----
                                                                       7.4%
                                                                     =====
</TABLE>

     The gross deferred tax assets were $13,000 as of December 31, 1997,
consisting of the state deferred income tax assets and liabilities for those
states who do not recognize S corporation status. Management considers
realization of the net deferred tax assets more likely than not due to
continued profitability of the Company and significant carryback opportunities.
 


(5) EMPLOYEE BENEFIT PLANS

     The Company has two Section 401(k) retirement savings plans (the Plans).
Under the terms of the Plans, employees may make contributions based on a
percentage of eligible earnings. Company contributions to the Plans are
discretionary and totaled $359,718 in 1997.


(6) STOCK OPTION PLAN

     The Company has 100,000 shares of common stock reserved for issuance under
its 1992 Incentive Stock Option Plan (the "Plan"). Under the Plan, the Company
may grant options to employees, officers, and directors. Options are granted at
prices not less than the fair market value of the Company's common stock as
determined by the Board of Directors on the grant date. Options vest ratably
over 48 months and expire 49 months from the date of grant.

     The Company applies Accounting Principles Board Opinion No. 25 (APB 25) in
accounting for its stock options. The exercise price for stock options granted
to employees in 1997 equaled the fair value of the Company's common stock at
the date of grant. Accordingly, in accordance with APB 25, no compensation
expense was recognized by the Company.

     For purposes of pro forma disclosures required by Statement of Financial
Accounting Standards No. 123 (SFAS 123), the compensation cost of the options,
based on their estimated fair values, is amortized to expense over the vesting
periods of the options. The Company's net income for the year ended December
31, 1997 would have reduced to the pro forma amounts indicated below:


<TABLE>
<S>                         <C>
   Net income:
    As reported .........    $6,854,742
                             ==========
    Pro forma ...........    $6,838,958
                             ==========
</TABLE>

     On January 1, 1997, the Company had no options outstanding. In July 1997,
the Company granted 25,000 options at an exercise price of $17.50, all of which
were outstanding but not exercisable as of December 31, 1997.


     The weighted-average grant-date fair value of options granted during the
year ended December 31, 1997 was $3.05 per option. The weighted-average
remaining contract life of the Company's outstanding stock options was 3.5
years at December 31, 1997.

     Pro forma information regarding net income as required by SFAS 123 has
been determined as if the Company had accounted for its employee stock options
under the fair value method. The fair value for the options was estimated at
the date of grant using the minimum value method prescribed in SFAS 123, which
does not consider the expected volatility of the Company stock price, with the
following weighted-average assumptions for 1997: risk free interest rate of
6.06%; dividend yield of 0%; and weighted-average expected option life of 3.25
years.


                                     F-105

(7) COMMITMENTS


     The Company leases certain facilities under operating leases that expire
at various dates through 2001. The Company in turn subleases some of these
facilities. As of December 31, 1997, future minimum lease payments under
noncancelable operating leases, exclusive of the sublease rentals, are as
follows:

                        REPORT OF INDEPENDENT AUDITORS



To the Board of Directors of
 L-3 Communications Corporation


     We have audited the accompanying combined balance sheet of AlliedSignal
Ocean Systems, a wholly owned operation of AlliedSignal, Inc. ("Ocean
Systems"), as of December 31, 1997 and the related combined statements of
operations, equity and cash flows for the year then ended. These financial
statements are the responsibility of Ocean System's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.


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


     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of Ocean Systems as
of December 31, 1997, and the combined results of their operations and cash
flows for the year ended December 31, 1997, in conformity with generally
accepted accounting principles.

                            (DOLLARS IN THOUSANDS)


1. BACKGROUND AND DESCRIPTION OF BUSINESS

     The Ocean Systems business ("Ocean Systems" or the "Company") is a wholly
owned operation of AlliedSignal Inc. ("AlliedSignal") comprised of the Ocean
Systems Division ("OS"), and AlliedSignal ELAC Nautik GmbH ("ELAC"). The OS
Division headquarters and principal operations, including one manufacturing
site, are located in Sylmar, California, a suburb of Los Angeles. OS also
operates marketing offices located in Canada ("ASCI") and England ("BOSL"). OS
was acquired through AlliedSignal's merger with the Bendix Corporation in 1982.
ELAC is a wholly owned subsidiary of AlliedSignal Deutschland ("AS
Deutschland") and is a separate legal entity located in Kiel, Germany. ELAC was
acquired from Honeywell Inc. in 1994.

     On December 22, 1997, L-3 Communications Corporation, a wholly owned
subsidiary of L-3 Communications Holdings, Inc. ("L-3") entered into a
definitive Purchase Agreement with AlliedSignal to acquire substantially all
the net assets excluding land and buildings, and assumed certain of the
liabilities of OS and purchased the outstanding capital stock of ELAC from AS
Deutschland.

     Ocean Systems develops, manufactures and sells sophisticated sonar
detection and tracking devices for underwater use. The Company's customers
include the U.S. Government, foreign governments, defense industry prime
contractors and commercial customers. The Company operates primarily in one
industry segment, electronic sonar components and systems.

     All domestic government contracts and subcontracts of Ocean Systems are
subject to audit and various cost controls, and Government contracts and
related orders are subject to cancellation if funds for contract performance
for any subsequent year become unavailable. Foreign government contracts
generally include comparable provisions relating to termination for the
convenience of the foreign government.

     The decline in the U.S. defense budget since the late 1980s has resulted
in program delays, cancellations and scope reduction for defense contracts in
general. These events may or may not have an effect on the Company's programs;
however, in the event that U.S. Government expenditures for products of the
type manufactured by the Company are reduced, and not offset by greater foreign
sales or other new programs or products, or acquisitions, there may be a
reduction in the volume of contracts or subcontracts awarded to the Company.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICES

BASIS OF PRESENTATION AND USE OF ESTIMATES

     The accompanying combined financial statements reflect the assets,
liabilities and operations of Ocean Systems including OS and ELAC which are
combined herein as they are entities under common control and management. All
significant intercompany accounts and transactions have been eliminated.

     The preparation of financial statements in conformity with generally
accepted accounting principals requires the Company's management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the combined financial statements and the reported amounts of revenue and
expenses during the reporting period. The most significant of these estimates
and assumptions relate to contract estimates of sales and costs, excess and
obsolete inventory reserves, warranty reserves, pension estimates and
recoverability of recorded amounts of fixed assets. Actual results could differ
from these estimates.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
                             (DOLLARS IN THOUSANDS)
 
REVENUE RECOGNITION

     Under fixed-price contracts, sales and related costs are recorded upon
delivery and customer acceptance. Sales and related costs under
cost-reimbursable contracts are recorded on the percentage of completion
method. Anticipated future losses on contracts are charged to income when
identified. Revisions in profit estimates are reflected in the period in which
the facts, which require the revision, become known.


ACCOUNTS RECEIVABLE

     Management assesses the credit risk and records an allowance for
uncollectable accounts as considered necessary based on several factors
including, but not limited to, an analysis of specific customers, historical
trends, current economic conditions and other information. The U.S. Navy
comprises a significant portion of Ocean System's revenues. The Company's other
customers include the navies of many foreign countries. The Company's credit
risk is affected by conditions or occurrences within the U.S. Government and
economic conditions of the countries in which the Company operates or has
customers. Sales are made on unsecured, customer-specific credit terms, which
may include extended terms.


INVENTORIES

     Inventories are valued at the lower of cost or market using the average
cost method. Inventories consist of raw materials and supplies, work in process
and finished goods. An excess and obsolete inventory reserve has been
established primarily for raw materials and parts that have not been allocated
to firm contracts. The excess and obsolete inventory reserve is based on
estimates of future usage of inventory on hand.

     Costs accumulated under cost-reimbursable contracts include direct costs,
as well as manufacturing overhead. In accordance with industry practice, these
amounts are included in current assets.


PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are stated at historical cost net of
accumulated depreciation. For financial purposes, property, plant and equipment
is generally depreciated on the straight line method using estimated useful
lives ranging from 3 to 20 years. Leasehold improvements are amortized over the
shorter of the lease term or the estimated useful life of the improvements.
Interest costs incurred during the construction of plant and equipment are
capitalized using an imputed interest rate approximating 8%. Interest costs
capitalized during 1997 amounted to $57.


CAPITALIZED SOFTWARE

     Capitalized software primarily represents costs incurred related to the
purchase and implementation of the Company's MRP II business system.
Capitalized software is reported at historical cost less accumulated
amortization. Amortization is based on the estimated useful service life not to
exceed five years. Amortization of capitalized software was $1,078 for the year
ended December 31, 1997. Accumulated amortization was $2,368 at December 31,
1997.

GOODWILL

     Goodwill represents the excess of the cost of the purchased business over
the net assets acquired and is being amortized on a straight-line basis over 40
years. This excess relates primarily to the allocated portion of goodwill
arising out of the AlliedSignal merger with Bendix in 1982 and was allocated to
OS based on the proportionate percentage of OS pretax earnings to the total
Bendix Aerospace Group pretax earnings at the time of the AlliedSignal
acquisition from Bendix. Amortization expense was $70 for the year ended
December 31, 1997. Accumulated amortization was $980 at December 31, 1997.

     The carrying amounts of intangible assets are reviewed if the facts and
circumstances indicate potential impairment of their carrying value. If this
review indicates that intangible assets are not recoverable, as determined
based on the undiscounted cash flows of the entity acquired over the remaining
amortization period, the Company's carrying values related to the intangible
assets are reduced to the fair value of the asset.


RESEARCH AND DEVELOPMENT AND SIMILAR COSTS

     Research and development costs sponsored by the Company include research
and development and bid and proposal efforts related to government products and
services. Customer-sponsored research and development costs incurred are
included in contract costs.


FOREIGN OPERATIONS AND FOREIGN CURRENCY TRANSLATION

     The Company's major foreign operation is ELAC located in Germany with the
Deutsche mark as its functional currency. Assets and liabilities are translated
at current exchange rates at the end of the period. Income and expenses are
translated using the monthly average exchange rates. The effect of the
unrealized rate fluctuations on translating foreign currency assets and
liabilities into U.S. dollars are accumulated as a separate component of equity
in the accompanying combined balance sheet.

     There are no material foreign currency gains or losses for the year ended
December 31, 1997 as the Company's U.S. sales to foreign customers are
denominated in U.S. dollars. ASCI Canadian sales are denominated in Canadian
dollars and the ELAC foreign sales are denominated in Deutsche marks.


FINANCIAL INSTRUMENTS

     At December 31, 1997, the carrying value of the Company's financial
instruments, such as receivables, accounts payable and accrued liabilities,
approximate fair value, based on the short-term maturities of these
instruments.


INCOME TAXES

     The benefit for income taxes for OS was computed by applying statutory tax
rates to the reported loss before income taxes after considering items that do
not enter into the determination of taxable income and tax credits reflected in
the consolidated provision of AlliedSignal which are related to OS. Income
taxes for OS are assumed to have been settled with AlliedSignal at December 31,
1997 and there are no separate tax attributes related to OS. For ELAC, separate
tax attributes that relate specifically to ELAC have been considered in
computing taxes.


3. TRANSACTIONS WITH ALLIEDSIGNAL

     Ocean Systems relies on AlliedSignal for certain services, including
treasury, cash management, employee benefits, taxes, risk management, internal
audit, financial reporting, legal, contract

administration and general corporate services. Although certain assets,
liabilities and expenses related to these services have been allocated to the
Company, the combined financial position, results of operations and cash flows
presented in the accompanying combined financial statements would not be the
same as would have occurred had the Company been an independent entity. The
following describes the related party transactions.


ALLOCATION OF CORPORATE EXPENSES


     The amount of allocated corporate expenses reflected in these combined
financial statements has been estimated based primarily on an allocation
methodology prescribed by government regulations pertaining to government
contractors. Corporate expenses allocated to Ocean Systems were $2,258 for the
year ended December 31, 1997, and are included in general and administrative
expense in the accompanying combined statement of operations.


PENSIONS


     Certain of the Company's employees participate in various AlliedSignal
sponsored pension plans covering certain employees. Eligibility for
participation in these plans varies, and benefits are generally based on
employees' compensation and years of service.


     AlliedSignal funding policy is generally to contribute in accordance with
cost accounting standards that affect government contractors subject to the
Internal Revenue code and regulations. Although the aforementioned pension
arrangements are part of certain AlliedSignal defined benefit plans, separate
actuarial estimates were made for the portion allocable to the Company. Pension
expense included in the accompanying combined statement of operations was
$1,452 for the year ended December 31, 1997. The pension plan liability at
December 31, 1997 was fully funded. The Company also has a supplemental pension
plan for highly compensated employees as defined by IRS rules. The liability
reflected in the accompanying combined balance sheet was $650 at December 31,
1997. Pension expense included in the combined statement of operations for the
supplemental pension plan was $24 for the year ended December 31, 1997.


     The Company's German employees of ELAC are covered by a separate pension
plan. Pension costs included the following components for the year ended
December 31, 1997:

POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS


     In addition to participating in AlliedSignal pension plans, employees of
OS are provided varying levels of health care and life insurance benefits for
retired employees and dependents. Participants are eligible for these benefits
when they retire from active service and meet the pension plan eligibility
requirements. These benefits are funded primarily on a pay-as-you-go basis with
the retiree generally paying of the cost through contributions, deductibles and
coinsurance provisions.


     Although the aforementioned postretirement benefits are part of certain
AlliedSignal postretirement arrangements, separate actuarial estimates were
made for the portion allocable to the Company. The weighted average discount
rate utilized in determining the accumulated postretirement benefit obligation
was 7.25% for 1997. Net postretirement benefit costs included in the combined
statements of operations was $1,072 for the year ended December 31, 1997.

EMPLOYEE SAVINGS PLANS

     Ocean Systems North American operation also has a supplemental savings
plan in which the Company matches the contributions of participating employees
up to a designated level. Under this plan, the matching contributions, in cash,
were $54 for the year ended December 31, 1997 and the liability recorded at
December 31, 1997 was $562.


INTEREST EXPENSE

     Interest expense has been allocated to the Company by applying
AlliedSignal's weighted average consolidated interest rate to the portion of
the beginning of the period equity account deemed to be financed by
consolidated debt, which has been determined based on AlliedSignal's debt to
equity ratio on such date. Management of the Company believes that this
allocation methodology is reasonable.

     The allocated interest expense was calculated using the following equity
balance and interest rate, for the year ended December 31, 1997:


<TABLE>

</TABLE>

     Allocated interest expense for the year ended December 31, 1997 amounted
to $552 and is included in interest expense, net in the accompanying combined
statement of operations.


INCOME TAXES

     The Company will be included in the consolidated Federal income tax
return, foreign tax returns and certain combined and separate state and local
income tax returns of AlliedSignal for 1997. Income taxes for OS are considered
to have been settled with AlliedSignal at December 31, 1997 and are recorded
through the invested equity account with AlliedSignal as there are no separate
stand alone tax attributes related to OS.

     ELAC participates in the AlliedSignal Deutschland GmbH profit pooling
agreement for corporate income tax and municipal trade tax. Since entering into
this agreement ELAC has not paid German taxes, as any profits or losses of ELAC
are transferred to AlliedSignal Deutschland. For purposes of these combined
financial statements, the tax attributes that relate to ELAC prior to entering
into the pooling agreement have been considered in computing the separate ELAC
tax computations as these attributes will remain with ELAC after the
termination of the pooling agreement after the acquisition by L-3.

operating loss ("NOL") carryovers amounted to $953 and $1,180, respectively,
and may be carried forward indefinitely.


     At December 31, 1997, deferred tax assets related to ELAC's German trade
tax and corporate income tax NOL carryovers amounted to $468. A full valuation
is recorded against the deferred tax asset.


     The valuation allowance for deferred taxes was based on ELAC's historical
losses from operations and its current year loss. In addition, certain aspects
of the acquisition could limit the utilization of a portion or all of these NOL
carryovers. Accordingly, management believes currently there is not enough
historical information to support that it is more likely than not that ELAC
will realize the future tax benefit of these NOL carryovers.


7. EQUITY


     Invested equity represents the equity contributed to OS by AlliedSignal
and related accumulated results of operations of OS. ELAC common stock
represents the one share of common stock held by AS Deutschland. ELAC's
retained earnings includes the impact of ELAC's accumulated operating losses,
and repayments to AlliedSignal offset by the effects of the amortization of
negative goodwill associated with the ELAC acquisition from Honeywell.


8. SALES TO PRINCIPAL CUSTOMERS


     The Company operates primarily in one industry segment, electronic sonar
components and systems. Sales to principal customers are as follows for the
year ended December 31, 1997:

9. COMMITMENTS AND CONTINGENCIES

     The Company leases certain facilities and equipment under agreements
expiring at various dates through 2011. At December 31, 1997, future minimum
payments for noncancellable operating leases with initial or remaining terms in
excess of one year are $933 for 1998, $340 for 1999, $161 for 2000, $35 for
2001 and $7 for 2002.

     Leases covering major items of real estate and equipment contain renewal
and or purchase options which may be exercised by the company. Rent expense,
net of sublease income from other AlliedSignal entities, was $1,342 for the
year ended December 31, 1997.

     Management is continually assessing the Company's obligations with respect
to applicable environmental protection laws. While it is difficult to determine
the timing and ultimate cost to be incurred by the Company in order to comply
with these laws, based upon available internal and external assessments, with
respect to those environmental loss contingencies of which management of the
Company is aware, the Company believes that even without considering potential
insurance recoveries, if any, there are no environmental loss contingencies
that individually or in the aggregate, would be material to the Company's
combined financial position, cash flows and results of operations. The Company
accrues for these contingencies when it is probable that a liability has been
incurred and the amount of the loss can be reasonably estimated.

     The Company is engaged in providing products and services under contracts
with the U.S. Government and foreign government agencies. All such contracts
are subject to extensive legal and regulatory requirements, and, from time to
time, agencies of the U.S. Government investigate whether such contracts were
and are being conducted in accordance with these requirements. Under government
procurement regulations, an indictment of the Company by a federal grand jury
could result in the Company being suspended for a period of time from
eligibility for awards of new government contracts. A conviction could result
in debarment from contracting with federal government for a specified term.

     The Company is also periodically subject to periodic review or audit by
agencies of the U.S. Government. At December 31, 1997, there are several
pending issues with these agencies that are incidental to the Company's
business. One of these reviews was critical of the Company's procedures for
maintaining control of Government owned property in the Company's custody. The
Company is responsible and liable for $93 million of Government-owned property
in its possession. With respect to this and other U.S. Government matters, the
Company's management believes the ultimate resolution of any such matters will
not have a material adverse effect on the combined financial position, cash
flows or results of operations of the Company.

                             (DOLLARS IN THOUSANDS)
 
     The Company is periodically subject to litigation, claims or assessments
and various contingent liabilities (including environmental matters) incidental
to their business. With respect to those investigative actions, items of
litigation, claims or assessments of which they are aware, management of the
Company is of the opinion that the probability is remote that, after taking
into account certain provisions that have been made with respect to these
matters, the ultimate resolution of any such investigative actions, items of
litigation, claims or assessments will have a material adverse effect on the
combined financial position, cash flows or results of operations of the
Company.

                     TRADING MARKET FOR THE EXCHANGE NOTES


     There is no existing trading market for the Exchange Notes, and there can
be no assurance regarding the future development of a market for the Exchange
Notes or the ability of the Holders of the Exchange Notes to sell their
Exchange Notes or the price at which such Holders may be able to sell their
Exchange Notes. If such market were to develop, the Exchange Notes could trade
at prices that may be higher or lower than their initial offering price
depending on many factors, including prevailing interest rates, the Company's
operating results and the market for similar securities. Although it is not
obligated to do so, Lehman Brothers Inc. intends to make a market in the
Exchange Notes. Any such market-making activity may be discontinued at any
time, for any reason, without notice at the sole discretion of Lehman Brothers
Inc. No assurance can be given as to the liquidity of or the trading market for
the Exchange Notes.


     Lehman Brothers Inc. may be deemed to be an affiliate of the Company and,
as such, may be required to deliver a prospectus in connection with its
market-making activities in the Exchange Notes. Pursuant to the Registration
Rights Agreement, the Company agreed to file and maintain a registration
statement that would allow Lehman Brothers Inc. to engage in market-making
transactions in the Exchange Notes. Subject to certain exceptions set forth in
the Registration Rights Agreement, the registration statement will remain
effective for as long as Lehman Brothers Inc. may be required to deliver a
prospectus in connection with market-making transactions in the Exchange Notes.
The Company has agreed to bear substantially all the costs and expenses related
to such registration statement.

     This prospectus is to be used by Lehman Brothers Inc. in connection with
offers and sales of the Exchange Notes in market-making transactions effected
from time to time. Lehman Brothers Inc. may act as a principal or agent in such
transactions, including as agent for the counterparty when acting as principal
or as agent for both counterparties, and may receive compensation in the form
of discounts and commissions, including from both counterparties when it acts
as agent for both. Such sales will be made at prevailing market prices at the
time of sale, at prices related thereto or at negotiated prices.


     Affiliates of Lehman Brothers Inc. currently own 36.6% of the Parent
Common Stock. See "Ownership of Capital Stock". Lehman Brothers Inc. has
informed the Company that it does not intend to confirm sales of the Exchange
Notes to any accounts over which it exercises discretionary authority without
the prior specific written approval of such transactions by the customer.


     The Company has been advised by Lehman Brothers Inc. that, subject to
applicable laws and regulations, Lehman Brothers Inc. currently intends to make
a market in the Exchange Notes following completion of the Exchange Offer.
However, Lehman Brothers Inc. is not obligated to do so and any such
market-making may be interrupted or discontinued at any time without notice. In
addition, such market-making activity will be subject to the limits imposed by
the Securities Act and the Exchange Act. There can be no assurance that an
active trading market will develop or be sustained. See "Risk Factors --
Trading Market for the Exchange Notes".


     Lehman Brothers Inc. has provided investment banking services to the
Company in the past and may provide such services and financial advisory
services to the Company in the future. Lehman Brothers Inc. acted as purchasers
in connection with the initial sale of the Notes and received an underwriting
discount of approximately $5.65 million in connection therewith. See "Certain
Transactions".


     Lehman Brothers Inc. and the Company have entered into a registration
rights agreement with respect to the use by Lehman Brothers Inc. of this

registration expenses incurred under such agreement, and the Company agreed to

                    INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law (the "DGCL") provides
for, among other things:

     a. permissive indemnification for expenses (including attorneys' fees),
   judgments, fines and amounts paid in settlement actually and reasonably
   incurred by designated persons, including directors and officers of a
   corporation, in the event such persons are parties to litigation other than
   stockholder derivative actions if certain conditions are met;

     b. permissive indemnification for expenses (including attorneys' fees)
   actually and reasonably incurred by designated persons, including directors
   and officers of a corporation, in the event such persons are parties to
   stockholder derivative actions if certain conditions are met;

     c. mandatory indemnification for expenses (including attorneys' fees)
   actually and reasonably incurred by designated persons, including directors
   and officers of a corporation, in the event such persons are successful on
   the merits or otherwise in defense of litigation covered by a. and b.
   above; and

     d. that the indemnification provided for by Section 145 is not deemed
   exclusive of any other rights which may be provided under any by-law,
   agreement, stockholder or disinterested director vote, or otherwise.

     In addition to the indemnification provisions of the DGCL described above,
the Registrant's certificate of incorporation (the "Certificate of
Incorporation") authorizes indemnification of the Registrant's officers and
directors, subject to a case-by-case determination that they acted in good
faith and in a manner they reasonably believed to be in or not opposed to the
best interests of the Company, and in the case of any criminal proceeding, they
had no reasonable cause to believe their conduct was unlawful. In the event
that a Change in Control (as defined in the Certificate of Incorporation) shall
have occurred, the proposed indemnitee director or officer may require that the
determination of whether he met the standard of conduct be made by special
legal counsel selected by him. In addition, whereas the DGCL would require
court-ordered indemnification, if any, in cases in which a person has been
adjudged to be liable to the Registrant, the Certificate of Incorporation also
permits indemnification in such cases if and to the extent that the reviewing
party determines that such indemnity is fair and reasonable under the
circumstances.

     The Certificate of Incorporation requires the advancement of expenses to
an officer or director (without a determination as to his conduct) in advance
of the final disposition of a proceeding if such person furnishes a written
affirmation of his good faith belief that he has met the applicable standard of
conduct and furnishes a written undertaking to repay any advances if it is
ultimately determined that he is not entitled to indemnification. In connection
with proceedings by or in the right of the Registrant, the Certificate of
Incorporation provides that indemnification shall include not only reasonable
expenses, but also penalties, fines and amounts paid in settlement. Unless
ordered by a court, such indemnification shall not include judgments. Under the
Certificate of Incorporation, no officer or director is entitled to
indemnification or advancement of expenses with respect to a proceeding brought
by him against the Registrant other than a proceeding seeking or defending such
officer's or director's right to indemnification or advancement of expenses.
Finally, the Certificate of Incorporation provides that the Company may,
subject to authorization on a case by case basis, indemnify and advance
expenses to employees or agents to the same extent as a director or to a lesser
extent (or greater, as permitted by law) as determined by the Board of
Directors.

     The Certificate of Incorporation purports to confer upon officers and
directors contractual rights to indemnification and advancement of expenses as
provided therein. In addition, as permitted by the


                                      II-1
<PAGE>
DGCL, the Registrant has entered into indemnity agreements with its directors
and selected officers that provide contract rights substantially identical to
the rights to indemnification and advancement of expenses set forth in the
Certificate of Incorporation, as described above.

     The Certificate of Incorporation limits the personal liability of
directors to the Registrant or its stockholders for monetary damages for breach
of the duty as a director, other than liability as a director (i) for breach of
duty of loyalty to the Registrant or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL (certain illegal
distributions), or (iv) for any transaction for which the director derived an
improper personal benefit.

     The Registrant maintains officers' and directors' insurance covering
certain liabilities that may be incurred by officers and directors in the
performance of their duties.

ITEM 22. UNDERTAKINGS.

     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 thereto, which, individually or in the aggregate,
   represent a fundamental change in the information set forth in the
   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.

     (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 therein, 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.

     The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed to be underwriters, in addition to the information
called for by the other Items of the applicable form.

     The Registrant undertakes that every prospectus (i) that is filed pursuant
to the immediately preceding undertaking or (ii) that purports to meet the
requirements of section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes 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
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     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 foregoing provisions, 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 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,


                                      II-5
<PAGE>

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.


     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

duly caused the Registration Statement or amendments thereto to be signed on
its behalf by the undersigned, thereunto duly authorized, on January 19, 1999.

redemption shall be given by first class mail, postage paid, mailed not less
than 15 days nor more than 60 days prior to the redemption date to each holder
of record of the shares of Preferred Stock at such holders's address as the
same appears on the stock register of the Corporation; provided, however, that

said notice or except as to the holder whose notice was defective. Each such
notice shall state: (i) the redemption date; (ii) the total number of shares of
Preferred Stock to be redeemed and the number of shares of Preferred Stock to
be redeemed from such holder; (iii) the redemption price; (iv) the place or

redemption date (unless default shall be made by the Corporation in providing
money for the payment of the redemption price of the shares of Preferred Stock
called for redemption), dividends on the shares of Preferred Stock so called
for redemption shall cease to accrue, and said shares shall no longer be deemed
to be outstanding and shall have the status of authorized but unissued shares
of Preferred Stock and all rights of the holders thereof as stockholders of the
Corporation (except the right to receive from the Corporation the redemption
price and any accrued and unpaid dividends without interest) shall cease. Upon
surrender in accordance with said notice of the certificates for any shares so
redeemed (properly endorsed or assigned for transfer, if the Board of Directors
of the Corporation shall so require and the notice shall so state), such shares
shall be redeemed by this Corporation at the redemption price.

         8. Voting Rights. The Holders of record of shares of Preferred
Stock shall not be entitled to any voting rights except as otherwise provided
by law.

         9.  Consents.  Without the affirmative vote of the holders of at least

                                   ARTICLE I

                         Shareholders' Meetings; Voting

         Section 1.1 Annual Meetings. An annual meeting of shareholders shall
be held for the election of directors on the first Monday in May of each year,
if not a legal holiday, and, if a legal holiday, then on the next day not a
legal holiday, at 10:00 o'clock in the forenoon at such time and place either
within or without the State of Delaware as may be designated by the Board of
Directors from time to time. Any other proper business may be transacted at
the annual meeting.

         Section 1.2. Special Meetings. Special meetings of shareholders may be
called at any time by the Chairman of the Board, the President, the Board of
Directors, or as provided in Section 2.2, to be held at such date, time and
place either within or without the State of Delaware as may be stated in the
notice of the meeting. A special meeting of shareholders shall be called by the
Secretary upon the written request, stating the purpose of the meeting, of
shareholders who together own of record at least ten percent (10%) of the
outstanding shares of stock entitled to vote at such meeting.

         Section 1.3. Notice of Meetings. Whenever shareholders are required
or permitted to take any action at a meeting, a written notice of the meeting
shall be given which shall state the place, date and hour of the meeting, and,
in the case of a special meeting, the purpose or purposes for which the meeting
is called. Unless otherwise provided by law, the written notice of any meeting
shall be given not less than ten nor more than sixty days before the date of
the meeting to each shareholder entitled to vote at such meeting. If mailed,
such notice shall be deemed to be given when deposited in the United States
mail, postage prepaid, directed to the shareholder at his address as it appears
on the records of the Corporation. The Corporation shall, at the written
request of any shareholder, cause such notice to such shareholder to be
confirmed to such other address and/or by such other means as such shareholder
may reasonably request, provided that if such written request is received after
the date any such notice is mailed, such request shall be effective for
subsequent notices only.

         Section 1.4. Adjournments. Any meeting of shareholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the Corporation may

 
<PAGE>


transact any business which might have been transacted at the original meeting.
If the adjournment is for more than thirty days, or if after the adjournment a
new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each shareholder of record entitled to Vote at the
meeting.

         Section 1.5. Quorum. At each meeting of shareholders, except where
otherwise provided by law or the certificate of incorporation or these by-laws,
the holders of a majority of the outstanding shares of each class of stock
entitled to vote at the meeting, present in person or represented by proxy,
shall constitute a quorum. With respect to any matter on which shareholders
vote separately as a class, the holders of a majority of the outstanding shares
of such class shall constitute a quorum for a meeting with respect to such
matter. Two or more classes or series of stock shall be considered a single
class for purposes of determining existence of a quorum for any matter to be
acted on if the holders thereof are entitled or required to vote together as a
single class at the meeting on such matter. In the absence of a quorum the
shareholders so present may, by majority vote, adjourn the meeting from time
to time in the manner provided by Section 1.4 of these by-laws until a quorum
shall attend.

         Section 1.6. Organization. Meetings of shareholders shall be presided
over by the Chairman of the Board, or in his absence by the President, or in
his absence by a Vice President, or in the absence of the foregoing persons by
a chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the chairman of the meeting may
appoint any person to act as secretary of the meeting.

         Section 1.7. Voting; Proxies. Unless otherwise provided in the
certificate of incorporation, each shareholder entitled to vote at any meeting
of shareholders shall be entitled to one vote for each share of stock held by
him which has voting power upon the matter in question. Each shareholder
entitled to vote at a meeting of shareholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person
or persons to act for him by proxy, but no such proxy shall be voted or acted
upon after three years from its date, unless the proxy provides for a longer
period. A duly executed proxy shall be irrevocable if it states that it is
irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support in irrevocable power. A shareholder may revoke any
proxy which is not irrevocable by attending the meeting and voting in person or
by filing an instrument in writing revoking the proxy or another duly executed
proxy bearing a later date with the Secretary of the Corporation. Voting at
meetings of shareholders need not be by written ballot and need not be
conducted by inspectors unless the holders of a majority of the outstanding
shares of any class of stock entitled to vote thereon present in person or by
proxy at such meeting shall so determine. At all meetings of shareholders for
the election of directors, such election and all other elections and questions
shall, unless otherwise provided by law or by the certificate of incorporation
or these by-laws, be decided by the vote of the holders of a majority of the
outstanding shares off all classes of stock entitled to vote thereon present in
person or by proxy at the meeting, voting as a single class.

         Section 1.8. Fixing Date for Determination of Shareholders of Record.
In order that the Corporation may determine the shareholders entitled to notice
of or to vote at any meeting of shareholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board
of Directors may fix, in advance, a record date, which shall not be more than
sixty nor less than ten days before the date of such meeting, nor more than
sixty days prior to any other action. If no record date is fixed: (1) the
record date for determining shareholders entitled to notice of or to vote at a
meeting of shareholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held; (2) the record date for determining shareholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the Board is necessary, shall be the day on which the first written consent
is expressed; and (3) the record date for determining shareholders for any
other purpose shall be at the close of business on the day on which the Board
adopts the resolution relating thereto. A determination of shareholders of
record entitled to notice of or to vote at a meeting of shareholders shall
apply to any adjournment of the meeting, provided, however, that the Board may
fix a new record date for the adjourned meeting.

         Section 1.9. List of Shareholders Entitled to Vote. The Secretary
shall prepare and make, at least ten days before every meeting of shareholders,
a, complete list of the shareholders entitled to vote at the meeting, arranged
in alphabetical order, and showing the address of each shareholder and the
number of shares registered in the name of each shareholder. Such list shall be
open to the examination of any shareholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten days
prior to the meeting, either at a place within the city where the meeting is to
be held, which place shall be specified in the notice of the meeting, or, if
not so specified, at the place where the meeting is to be held. The list shall
also be produced and kept at the time and place of the meeting during the
whole time thereof and may be inspected by my shareholder who is present.

         Section 1.10. Consent of Shareholders in Lieu of Meeting. To the
extent provided by any statute at the time in force, whenever the vote of
shareholders at a meeting thereof is required or permitted to be taken for or
in connection with any corporate action, by any statute, by the certificate of
incorporation or by these by-laws, the meeting and prior notice thereof and
vote of shareholders may be dispensed with if the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted shall consent in writing to such corporate
action without a meeting by less than unanimous written consent and notice
thereof shall be given to those shareholders who have not consented in writing.

of the Corporation shall be managed by or under the direction of the Board of
Directors, except as may be otherwise provided by law or in the certificate of
incorporation. The number of Directors which shall constitute the whole Board
of Directors shall not be less than one (1) nor more than eight (8). Within
such limits, the number of directors may be fixed from time to time by vote of
the shareholders or of the Board of Directors, at any regular or special
meeting, subject to the provisions of the certificate of incorporation.

         Section 2.2. Election: Term of Office, Resignation; Removal;
Vacancies; Special Elections. Except as otherwise provided in this Section 2.2,
the directors shall be elected annually at the annual meeting of the
shareholders. Each director (whenever elected) shall hold office until the
annual meeting of shareholders or any special meeting of shareholders called to
elect directors next succeeding his election and until his successor is elected
and qualified or until his earlier resignation or removal, except as provided
in the certificate of incorporation. Any director may resign at any time upon
written notice to the Board of Directors or to the Chairman of the Board or to
the President of the Corporation. Such resignation shall take effect at the
time specified therein, and unless otherwise specified therein no acceptance of
such resignation shall be necessary to make it effective. Any director may be
removed with or without cause at any time upon the affirmative vote of the
holders of a majority of the outstanding shares of stock of the Corporation
entitled to vote for the election of such director, given at a special meeting
of such shareholders called for the purpose. If any vacancies shall occur in
the Board of Directors, by reason of death, resignation, removal or otherwise,
or if the authorized number of directors shall be increased, the directors then
in office shall continue to act, and such vacancies may be filled by a majority
of the directors then in office, though less than a quorum; provided, however,
that whenever the holders of any class or classes of stock or series thereof
are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series shall be filled by a majority of the directors
elected by such class or classes or series thereof then in office though less
than a quorum or by a sole remaining director so elected. Any such vacancies or
newly created directorships may also be filled upon the affirmative vote of the
holders of a majority of the outstanding shares of stock of the Corporation
entitled to vote for the election of directors, given at a special meeting of
the shareholders called for the purpose.

         Section 2.3. Regular Meetings. Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware
and at such times as the Board may from time to time determine, and if so
determined notice thereof need not be given.

         Section 2.4. Special Meetings Special meetings of the Board of
Directors may be held at any time or place within or without the State of
Delaware whenever called by the Chairman of the Board, by the President or by
any two directors. Reasonable notice thereof shall be given by the person or
persons calling the meeting.

         Section 2.5. Telephonic Meetings Permitted. Unless otherwise
restricted by the certificate of incorporation or these by-laws, any member of
the Board of Directors, or any committee designated by the Board, may
participate in a meeting of the Board or of such committee, as the case may be,
by means of a conference telephone or similar communications equipment by means
of which all persons participating in the meeting can hear each other, and

     were not such director or officer of such other corporation, or not so
     interested.

     directors may be ratified by a vote of a majority of the shares having
     voting powers at any meeting of stockholders, or at any special meeting
     called for such purpose, and such ratification shall, so far as permitted

the question; except in any case where a larger vote is required by law, by the

Shares of the capital stock of the corporation belonging to the corporation
shall not be voted upon directly or indirectly.

         Persons holding stock in a fiduciary capacity shall be entitled to
vote the shares so held, or to give any consent permitted by law, and persons
whose stock is pledged shall be entitled to vote, or to give any consent
permitted by law, unless in the transfer by the pledgor on the books of the

thereon or give any such consent.

         The secretary shall prepare and make, at least ten days before
every election of directors, a complete list of the stockholders entitled to
vote at said election, arranged in alphabetical order, and showing the address
of each stockholder and the number of shares registered in the name of each

during ordinary business hours, at the place where said election is to be
held, for said ten days, and shall be produced and kept at the time and place
of election during the whole time thereof, and subject to the inspection of any
stockholder who may be present. The original or duplicate stock ledger shall be
the only evidence as to who are stockholders entitled to examine such list or
to vote in person or by proxy at such election.

until the next annual meeting of the stockholders and until his successor is
elected and qualified, or until he sooner dies, resigns or is removed or
replaced.

         Regular meetings of the board of directors may be held without call or
formal notice at such places either within or without the State of Delaware and
at such times as the board may from time to time determine. A regular meeting
of the board of directors may be held without call or formal notice immediately
after and at the same place as the annual meeting of the stockholders.

         Special meetings of the board of directors may be held at any time and
at any place either within or without the State of Delaware when called by the

call or formal notice if each director then in office waives notice before or
after the meeting. A waiver of notice in writing, signed by a director entitled
to such notice, whether before or after the time of the meeting, shall be
deemed equivalent to such notice to him. In any case it shall be deemed
sufficient notice to a director to send notice by mail at least forty-eight
hours or by telegram at least twenty-four hours before the meeting addressed to
him at his usual or last known business or residence address or to give notice
to him in person either by telephone or by handing him a written notice at

election or for the consideration of any question shall consist of three
directors, but any meeting may be adjourned from time to time by a majority of
the votes cast upon the question, whether or not a quorum is present, and the
meeting may be held as adjourned without further notice. When a quorum is
present at any meeting, the votes of a majority of the directors present and
voting shall be requisite and sufficient for election to any office, and a
majority of the directors present and voting shall decide any question brought
before such meeting, except in any case where a larger vote is required by law,
by the certificate of incorporation or by these by-laws. Any action required of
the board of directors may be taken by a written and unanimous consent of all
directors then in office.

and the president, or in lieu of the president, a vice president or the
treasurer or an assistant treasurer or the secretary or an assistant secretary
of the corporation, certifying the number of shares owned by him in the
corporation; provided, however, that where such certificate is signed (1) by a
transfer agent or an assistant transfer agent or (2) by a transfer clerk acting
on behalf of the corporation and a registrar, the signatures of the chairman of
the board, president, vice president, treasurer, assistant treasurer, secretary
or assistant secretary may be facsimile. In case any officer or officers who
shall have signed, or whose facsimile signature or signatures shall have been
used on, any such certificate or certificates shall cease to be such officer or
officers of the corporation, whether because of death, resignation or
otherwise, before such certificate or certificates shall have been delivered by
the corporation, such certificate or certificates may nevertheless be adopted
by the corporation and be issued and delivered as though the person or persons
who signed such certificate or certificates or whose facsimile signature or
signatures have been used thereon had not ceased to be such officer or officers
of the corporation, and any such issue and delivery shall be regarded as an


                                      10

adoption by the corporation of such certificate or certificates. Certificates
of stock shall be in such form as shall, in conformity to law, be prescribed

certificate of stock and to the shares represented thereby shall be transferred
only by delivery of the certificate properly endorsed, or by delivery of the
certificate accompanied by a written assignment of the same, or a written power
of attorney to sell, assign or transfer the same or the shares represented
thereby, properly executed; but the person registered on the books of the
corporation as the owner of shares shall have the exclusive right to receive
dividends thereon and, except as provided in Article VII with respect to stock
which has been pledged, to vote thereon as such owner or to give any consent
permitted by law, and shall be held liable for such calls and assessments, if
any, as may lawfully be made thereon, and except only as may be required by
law, may in all respects be treated by the corporation as the exclusive owner
thereof. It shall be the duty of each stockholder to notify the corporation of
his post office address.

or exchange of capital stock shall go into effect or for a period of not
exceeding fifty days in connection with obtaining the consent of stockholders

books as aforesaid, the board of directors may fix in advance a date, not
exceeding fifty days preceding the date of any meeting of stockholders, or any
other of the above mentioned events, or a date in connection with obtaining
such consent, as a record date for the determination of the stockholders
entitled to notice of, or to vote at, any such meeting and any adjournment
thereof, or entitled to receive payment of any such dividend, or to any such
allotment of rights, or to exercise the rights in respect of any such change,
conversion or exchange of capital

stock, or to give such consent, and in such case such stockholders and only
such stockholders as shall be stockholders of record on the date so fixed shall
be entitled to such notice of, and to vote at, such meeting and any adjournment
thereof, or to receive payment of such dividend, or to receive such allotment
of rights, or to exercise such rights, or to give such consent, as the case may
be, notwithstanding any transfer of any stock on the books of the corporation
after any such record date fixed as aforesaid.

transfers, contracts, bonds, notes, checks, drafts and other obligations made,
accepted or endorsed by the corporation shall be signed by the president or by
one of the vice presidents or by the treasurer.

                                 INDEMNIFICATION

         Section 1. Power to Indemnify in Actions, Suits or Proceedings other
than those by or in the Right of the Corporation. Subject to Section 3 of this
Article XXIX, the corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director or officer of the corporation,
or is or was serving at the request of the corporation as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interest of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         Section 2. Power to Indemnify in Actions, Suits or Proceedings by or
in the Right of the Corporation. Subject to Section 3 of this Article XXIX, the
corporation shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by
or in the right of the corporation to procure a judgment in its favor by reason
of the fact that he is or was a director or officer of the corporation, or is
or was serving at the request of the corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interest of the corporation; except that no indemnification
shall be made in

                                      14

<PAGE>

respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
or such other court shall deem proper.

         Section 3. Authorization of Indemnification. Any indemnification under
this Article XXIX (unless ordered by a court) shall be made by the corporation
only as authorized in the specific case upon a determination that
indemnification of the director or officer is proper in the circumstances
because he has met the applicable standard of conduct set forth in Section 1 or
Section 2 of this Article XXIX, as the case may be. Such determination shall be
made (i) by the Board of Directors by a majority vote consisting of directors
who were not parties to such action, suit or proceeding, or (ii) if a quorum of
the Board of Directors is not obtainable, by the stockholders. To the extent,
however, that a director or officer of the corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding described
above, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith, without the necessity of
authorization in the specific case.

         Section 4. Good Faith Defined. For purposes of any determination under
Section 3 of this Article XXIX, a person shall be deemed to have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, or, with respect to any criminal action or
proceeding, to have had no reasonable cause to believe his conduct was
unlawful, if his action is based on the records or books of account of the
corporation or another enterprise, or on information supplied to him by the
officers of the corporation or another enterprise in the course of their
duties, or on the advice of legal counsel for the corporation or another
enterprise or on information or records given or reports made to the
corporation or another enterprise by an independent certified public accountant
or by an appraiser or other expert selected with reasonable care by the
corporation or another enterprise. The term "another enterprise" as used in
this Section 4 shall mean any other corporation or any partnership, joint
venture, trust or other enterprise of which such person is or was serving at
the request of the corporation as a director, officer, employee or agent. The
provisions of this Section 4 shall not be

                                       15

<PAGE>


deemed to be exclusive or to limit in any way the circumstances in which a
person may be deemed to have met the applicable standard of conduct set forth
in Sections 1 or 2 of this Article XXIX, as the case may be.

         Section 5. Indemnification by a Court. Notwithstanding any contrary
determination in the specific case under Section 3 of this Article XXIX, and
notwithstanding the absence of any determination thereunder, any director or
officer may apply to any court of competent jurisdiction in the State of
Delaware for indemnification to the extent otherwise permissible under Sections
1 and 2 of this Article XXIX. The basis of such indemnification by a court
shall be a determination by such court that indemnification of the director or
officer is proper in the circumstances because he has met the applicable
standards of conduct set forth in Sections 1 or 2 of this Article XXIX, as the
case may be. Notice of any application for indemnification pursuant to this
Section 5 shall be given to the corporation promptly upon the filing of such
application.

         Section 6. Expenses Payable in Advance. Expenses incurred in
defending or investigating a threatened or pending action, suit or proceeding,
may be paid by the corporation in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of
the director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized in this Article XXIX.

         Section 7. Non-exclusivity and Survival of Indemnification. The
indemnification and advancement of expenses provided by or granted pursuant to
this Article XXIX shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
any by-law, agreement, contract, vote of stockholders or disinterested
directors or pursuant to the direction (howsoever embodied) of any court of
competent jurisdiction or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office, it
being the policy of the corporation that indemnification of the persons
specified in Sections 1 and 2 of this Article XXIX shall be made to the
fullest extent permitted by law. The provisions of this Article XXIX shall not
be deemed to preclude the indemnification of any person who is specified in
Sections 1 or 2 of this Article XXIX but whom the corporation has the
obligation to indemnify under the provisions of the General Corporation Law of
the State of Delaware, or otherwise. The indemnification and advancement of
expenses provided by, or granted pursuant to, this Article XXIX shall, unless
otherwise provided when authorized or ratified, continue as to a person who has

                                      16

<PAGE>


ceased to be a director or officer and shall inure to the benefit of the heirs,
executors and administrators of such person.

         Section 8. Insurance. The corporation may purchase and maintain
insurance on behalf of any person who is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
corporation would have the power or the obligation to indemnify him against
such liability under the provisions of this Article XXIX.

         Section 9. Meaning of "Corporation" for Purposes of Article XXIX. For
purposes of this Article XXIX, references to "the corporation" shall include,
in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors and officers so that any person who is or
was a director or officer of such constituent corporation, or is or was
serving at the request of such constituent corporation as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article XXIX with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

<PAGE>




         SECTION 6. SHAREHOLDERS ACTING WITHOUT A MEETING - DIRECTORS. Any 
action which may be taken at a meeting of the Shareholders may be taken without
a meeting, or notice of meeting if authorized by a writing signed by all of the
shareholders entitled to vote at a meeting for such purpose, and filed with the
Secretary of the corporation, provided, further, that while ordinarily
Directors can only be elected by unanimous written consent under Sec. 603 (d),
if the Directors fail to fill a vacancy, then a Director to fill that vacancy
may be elected by the written consent of persons holding a majority of shares
entitled to vote for the election of Directors.

         SECTION 7. OTHER ACTIONS WITHOUT A MEETING. Unless otherwise provided
in the General Corporation Law or the Articles, any action which may be taken
at any annual or special meeting of Shareholders may be taken without a meeting
and without prior notice, if a consent in writing, setting forth the action so
taken, signed by the holders or outstanding shares having not less than the
minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.

         Unless the consents of all Shareholders entitled to vote have been
solicited in writing,

         (1) Notice of any Shareholder approval pursuant to Secs. 310, 317, 
1201 or 2007 without a meeting by less than unanimous written consent shall be
given at least ten (10) days before the consummation of the action authorized by
such approval, and

         (2) Prompt notice shall be given of the taking of any other corporate
action approved by Shareholders without a meeting by less than unanimous
written consent, to each of those Shareholders entitled to vote who have not
consented in writing.

         Any Shareholder giving a written consent, or the Shareholder's
proxyholders, or a transferee of the shares of a personal representative of the
Shareholder or their respective proxy-holders, may revoke the consent by a
writing received by the corporation prior to the time that written consents of
the number of shares required to authorize the proposed action have been filed
with the Secretary of the corporation, but may not do so thereafter. Such
revocation is effective upon its receipt by the Secretary of the corporation.

         SECTION 8. QUORUM. The holders of a majority of the shares entitled to
vote thereat, present in person, or represented by proxy, shall constitute a
quorum at all meetings of the Shareholders for the transaction of business

these By-Laws. If, however, such majority shall not be present or represented
at any meeting of the Shareholders, the Shareholders entitled to vote thereat,
present in person, or by proxy, shall have the power to adjourn the meeting
from time to

                                    PAGE 11



<PAGE>




time, until the requisite amount of voting shares shall be present. At such
adjourned meeting at which the requisite amount of voting shares shall be
represented, any business may be transacted which might have been transacted
at a meeting as originally notified.

         If a quorum be initially present, the Shareholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
Shareholders to leave less than a quorum, if any action taken is approved by a
majority of the Shareholders required to initially constitute a quorum.

         SECTION 9. VOTING. Only persons in whose names shares entitled to vote
stand on the stock records of the corporation on the day of any meeting of
Shareholders, unless some other day be fixed by the Board of Directors for the
determination of Shareholders of record, and then on such other day, shall be
entitled to vote at such meeting.

         Provided the candidate's name has been placed in nomination prior to
the voting and one or more Shareholder has given notice at the meeting prior to
the voting of the Shareholder's intent to cumulate the Shareholder's votes,
every Shareholder entitled to vote at any election for Directors of any
corporation for profit may cumulate their votes and give one candidate a number
of votes equal to the number of Directors to be elected multiplied by the
number of votes to which his or her shares are entitled, or distribute his or
her votes on the same principle among as many candidates as he or she thinks
fit.

         The candidates receiving the highest number of votes up to the number
of Directors to be elected are elected.

         The Board of Directors may fix a time in the future not exceeding
thirty (30) days preceding the date of any meeting of Shareholders or the date
fixed for the payment of any dividend or distribution, or for the allotment of
rights, or when any change or conversion or exchange of shares shall go into 
effect, as a record date for the termination of the Shareholders entitled to
notice of and to vote at any such meeting, or entitled to receive any such
dividend or distribution, or any allotment of rights, or to exercise the rights
in respect to any such change, conversion or exchange of shares. In such case
only Shareholders of record on the date so fixed shall be entitled to notice
of and to vote at such meeting, or to receive such dividends, distribution or
allotment of rights, or to exercise such rights, as the case may be
notwithstanding any transfer of any share on the books of the corporation after
any recorded date fixed as aforesaid. The Board of Directors may close the
books of the corporation against transfers of shares during the whole or any
part of such period.

the Secretary of the corporation.

         SECTION 11. ORGANIZATION. The President, or in the absence of the
President, any Vice President, shall call the meeting of the Shareholders to
order, and shall act as Chairman of the meeting. In the absence of the
President and all of the Vice Presidents, Shareholders shall appoint a chairman
for such meeting. The Secretary of the corporation shall act as Secretary of
all meetings of the Shareholders, but in the absence of the Secretary at any
meeting of the Shareholders, the presiding Officer may appoint any person to
act as Secretary of the meeting.

         SECTION 12. INSPECTORS OF ELECTION. In advance of any meeting of
Shareholders the Board of Directors may, if they so elect, appoint inspectors
of election to act at such meeting or any adjournment thereof. If inspectors of
election be not so appointed, or if any persons so appointed fail to appear or
refuse to act, the chairman of any such meeting may, and on the request of any
Shareholder or his or her proxy shall, make such appointment at the meeting in
which case the number of inspectors shall be either one (1) or three (3) as
determined by a majority of the Shareholders represented at the meeting.

         SECTION 13. SHAREHOLDERS' AGREEMENTS.

         Notwithstanding the above provisions, in the event this corporation
elects to become a close corporation, an agreement between two (2) or more
Shareholders thereof, if in writing and signed by the parties thereof, may
provide that in exercising any voting rights the shares held by them shall be
voted as provided therein or in Sec. 706, and may otherwise modify these
provisions as to Shareholders' meetings and actions.

         SECTION 14. EFFECT OF SHAREHOLDERS' AGREEMENTS. Any shareholders'
Agreement authorized by Sec. 300 (b), shall only be effective to modify the
terms of these By-Laws if this corporation elects to become a close corporation
with appropriate filing of or amendment to its Articles as required by Sec. 202
and shall terminate when this corporation ceases to be a close corporation.
Such an agreement cannot waive or alter Secs. 158, (defining close
corporations), 202 (requirements of Articles of Incorporation) 500 and 501
relative to distributions, 1100 et. seq. (merger), 1201 (e) (reorganization) or
Chapters 15 (Records and Reports), 16 (Rights of Inspection), 18 (Involuntary
Dissolution) or 22 (Crimes and Penalties). Any other provisions of the Code or
these By-Laws may be altered or waived thereby, but to the extent they are not
so altered or waived, these By-Laws shall be applicable.

of such form and device as the Board of Directors may designate and shall state
the name of the record holder of the shares represented thereby; its number;
date of issuance; the number of shares for which it is issued; a statement of
the rights, privileges, preferences and restrictions, if any; a statement as to
the redemption or conversion, if any; a statement of liens or restrictions upon

collectible by personal action, a plain statement of such facts.

         All certificates shall be signed in the name of the corporation by the
Chairman of the Board of Vice Chairman of the Board or the President or Vice
President and by the Chief Financial Officer or an Assistant Treasurer or the
Secretary or any Assistant Secretary, certifying the number of shares and the
class or series of shares owned by the Shareholder.

         Any or all of the signatures on the certificate may be facsimile. In
case any Officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed on a certificate shall have ceased to be
that Officer, transfer agent, or registrar before that certificate is issued,
it may be issued by the corporation with the same effect as if that person were
an Officer, transfer agent, or registrar at the date of issue.

         SECTION 2. TRANSFER ON THE BOOKS. Upon surrender to the Secretary or
transfer agent of the corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

         SECTION 3. LOST OR DESTROYED CERTIFICATES. Any person claiming a
certificate of stock to be lost or destroyed shall make an affidavit or
affirmation of that fact and shall, if the Directors so require, give the
corporation a bond of indemnity, in the form and with one or more sureties
satisfactory to the Board, in at least double the value of the stock
represented by said certificate, whereupon a new certificate may be issued in
the same tenor and for the same number of shares as the one alleged to be lost
or destroyed.

deletion.

         SECTION 8. PROVISION RESTRICTING TRANSFER OF SHARES. Before there can
be a valid sale or transfer of any of the shares of this corporation by the
holders thereof, the holder of the shares to be sold or transferred shall
first give notice in writing to be Secretary of this Corporation of his or
her intention to sell or transfer such shares. Said notice shall specify the
number of shares to be sold or transferred, the price per share and the terms
upon which such holder intends to make such sale or transfer. The Secretary
shall within five (5) days thereafter, mail or deliver a copy of said notice to
each of the other Shareholders of record of this corporation. Such notice may
be delivered to such Shareholders personally or may be mailed to the last known
addresses of such Shareholders, as the same may appear on the books of this
corporation. Within    days after the mailing or delivery of said notices to 
such Shareholders, any such Shareholder or Shareholders desiring to acquire any
part or all of the shares referred to in said notice shall deliver by mail or
otherwise to the Secretary of this corporation a written offer or offers to
purchase a specified number or numbers of such shares at the price and upon the
terms stated in said notice.

         If the total number of shares specified in such offers exceeds the
number of shares referred to in said notice, each offering Shareholder shall be
entitled to purchase such proportion of the shares referred to in said notice
to the Secretary, as the number of shares of this corporation, which he or she
holds, bears to the total number of shares held by all Shareholders desiring to
purchase the shares referred to in said notice to the Secretary.

         If all of the shares referred to in said notice to the Secretary are
not disposed of under such apportionment, each Shareholder desiring to purchase
shares in a number in excess of his or her proportionate share, as provided
above, shall be entitled to purchase such proportion of those shares which
remain thus undisposed of, as the total number of shares which he or she holds
bears to the total number of shares held by all of the Shareholders desiring to
purchase shares in excess of those to which they are entitled under such
apportionment.

         The aforesaid right to purchase the shares referred to in the
aforesaid notice to the Secretary shall apply only if all of the share referred
to in said notice are purchased. Unless all of the shares referred to in said
notice to the Secretary are purchased, as aforesaid, in accordance with offers
made within said days, the Shareholder desiring to sell or transfer may dispose
of all shares of stock referred to in said notice to the Secretary to any
person or persons whomsoever; provided, however, that he or she shall not sell
or transfer such shares at a lower price or on terms more favorable to the
purchaser or transferee than those specified in said notice to Secretary.

said corporation shall be null and void unless the terms, conditions and 
provisions of this section are strictly observed and followed.

         SECTION 9. PLEDGED OR HYPOTHECATED SHARES. Any Shareholder desiring to
borrow money on or hypothecate any or all of the shares of stock held by such
Shareholder shall first mail notice in writing to the Secretary of this
corporation of his or her intention to do so. Said notice shall specify the
number of shares to be pledged or hypothecated, the amount to be borrowed per
share, the terms, rate of interest, and other provisions upon which each
Shareholder intends to make such loan or hypothecation. The Secretary shall,
within five (5) days thereafter, mail or deliver a copy of said notice to each
of the other Shareholders of record of this corporation. Such notice may be
delivered to such Shareholder personally, or may be mailed to the last known
addresses of such Shareholders as the same may appear on the books of this
corporation. Within fifteen (15) days after the mailing or delivering of said
notice to said Shareholders, any such Shareholder or Shareholders desiring to
lend any part or all of the amount sought to be borrowed, as set forth in said
notice, at the terms therein specified, shall deliver by mail, or otherwise, to
the Secretary of this corporation a written offer or offers to lend a certain
amount of money for the term, at the rate of interest, and upon the other
provisions specified in said notice.

         If the total amount of money subscribed in such offers exceeds the
amount sought to be borrowed, specified in said notice, each offering
Shareholder shall be entitled to lend such proportion of the amount sought to
be borrowed, as set forth in said notice, as the number of shares which he or
she holds bears to the total number of shares held by all such Shareholders
desiring to lend all or part of the amount specified in said notice.

         If the entire amount of monies sought to be borrowed, as specified in
said notice, is not subscribed as set forth in the preceding paragraphs, each
Shareholder desiring to lend an amount in excess of his or her proportionate
share, as specified in the preceding paragraph, shall be entitled to lend such
proportion of the subscribed amount as the total number of share which he or
she holds bears to the total number of shares held by all of the Shareholders
desiring to lend an amount in excess of that to which they are entitled under
such apportionment. If there be but one Shareholder so desiring to lend, such
Shareholder shall be entitled to lend up to the full amount sought to be
borrowed.

         If none, or only a part of the amount sought to be borrowed, as
specified in said notice, is subscribed as aforesaid, in accordance with offers
made within said fifteen (15) day period, the Shareholder desiring to borrow
may borrow from any person or persons he or she may so desire as to any or all
shares of stock held by him or her which have not been covered by lending
Shareholders; provided, however, that said Shareholders shall not borrow any
lesser amount, or any amount on terms less favorable to the borrower, than
those specified in said notice to the Secretary.

         Any pledge or hypothecation, or other purported transfer as security
for a loan of the shares of this corporation, shall be null and void unless the
terms, conditions and provisions of these By-Laws are strictly observed and
followed.

pursuant to Section 4(a) shall be reduced by the aggregate Shareholder Set-Off

mutilated, the Company shall issue a new certificate in place of such mutilated
certificate. In case any such certificate shall be lost, stolen or destroyed,

designated thereby with power so to act, issue a new certificate for capital
stock in the place of any such lost, stolen or destroyed certificate. The
applicant for any substituted certificate or certificates shall surrender any
mutilated certificate or, in the case of any lost, stolen or destroyed
certificate, furnish satisfactory proof of such loss, theft or destruction of

with an acceptable surety or sureties and in such sum as will be sufficient to
indemnify the Company against any claim that may be made against it on account

of any rights, or to exercise any rights in respect of any change, conversion or
exchange of stock or for the purpose of any other lawful action.

            (b) If no record date is fixed by the Board of Directors:

            (i) The record date for determining stockholders entitled to notice
      of or to vote at a meeting of stockholders shall be at the close of
      business on the day next preceding the day on which notice is given, or if
      notice is waived at the close of business on the day next preceding the
      day on which the meeting is held;

            (ii) The record date for determining stockholders entitled to
      express consent to corporate action in writing without a meeting when no

party or is threatened to be made a carry to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, including any action, suit or proceeding by or in the right of
the Corporation, by reason of the fact that he is or was a director, officer,
employee, or agent of the authorization, or is or was serving at the request of
the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, including in
any capacity with respect to an employee benefit plan, shall be indemnified by
the Corporation against any and all liability, expenses (including attorney's

<PAGE>

the fullest extent permitted by the Delaware General Corporation Law, as the
same exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than permitted by such law prior to such
amendment). Such indemnification shall continue as to a person who has ceased to
be a director, officer, employee or agent of the Corporation and shall inure to
the benefit of his heirs, executors and administrators.

            5.02 Advance of Expenses. The Corporation shall have the right, but
not the obligation, to pay expenses incurred by any Director or officer of the

advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director or officer to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Corporation as authorized in this Section 5. Such expenses
incurred by other employees and agents may also be so paid upon such terms and
conditions, as the Board of Directors deems appropriate.

            5.03 Non-Exclusivity. The right to indemnification and payment of
expenses provided in Section 5 shall not be deemed to be exclusive of any other
rights to which the person seeking indemnification or payment of expenses may be
entitled under


                                      -11-

these Bylaws or any agreement by or with the Corporation, by vote of
stockholders or disinterested directors of the Corporation, or otherwise.

            5.04 Joint Indemnification. The amounts to be paid for or on behalf
of any person by the Corporation as indemnification under these bylaws or
applicable law with respect to any matter shall be reduced by the amount such
person is entitled to receive as indemnification for the same matter from any
other source.

            5.05 Insurance. The Corporation may, at its own expense, maintain
insurance to protect itself and any Director, officer, employee or agent of the
Corporation, or another corporation, partnership, joint venture, trust or other
enterprise against any liability, expense, judgment or loss, whether or not the
Corporation would have the power to indemnify such person against such
liability, expense, judgment, fine or loss under the Delaware General
Corporation Law.

                                      -12-

physically or mentally incapacitated or shall disappear, as a result of which a
quorum of stockholders or directors cannot be readily convened or communicated
with, for the purposes of action believed to be necessary or desired by a
majority of the remaining stockholders or directors:

                  (a) A meeting of the stockholders or directors may be called
by any member thereof in the manner otherwise provided for in these Bylaws;

                  (b) The stockholders or directors, as the case may be, who are
not rendered unavailable as aforesaid shall be deemed to be the entirety of the
body of stockholders or of the Board of Directors for all purposes, and their
actions, if otherwise in conformity with these Bylaws and applicable law, shall
be as valid and effective as if taken with the participation and assent of the
persons so rendered unavailable.

            The minutes of every emergency meeting held, and every written
consent executed, under authority of this Section 6 shall be distributed to the
missing person or persons as promptly as practicable. In no event shall any
action be taken under this Section 6 by less than two of the stockholders or two

incurred by him in connection with any such action, suit or proceeding to the

otherwise.

            5.04 Joint Indemnification. The amounts to be paid for or on behalf

other source.

            5.05 Benefits to Survive. The indemnification and advancement of
expenses provided by, or granted pursuant to, this section shall, unless

investigative, including any action by or in the right of the Corporation, by
reason of the fact that he is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, including in any capacity with respect to an
employee benefit plan, shall be indemnified by the Corporation against any and
all liability, expenses (including attorney's fees), judgments and losses

<PAGE>

suit or proceeding to the fullest extent permitted by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the

prior to such amendment). Such indemnification shall continue as to a person who

shall inure to the benefit of his heirs, executors and administrators.

final disposition of such action, suit, or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Section 5. Such expenses incurred by other
employees and agents may also be so paid upon such terms and conditions, if any,
as the Board of Directors deems appropriate.

            5.03 Non-Exclusivity. The right to indemnification and payment of
expenses provided in Section 5 shall not be deemed to be exclusive of any other
rights to which the person seeking indemnification or payment of expenses may be
entitled under these By-Laws or any agreement by or with the Corporation, by
vote of stockholders or disinterested directors of the Corporation, or
otherwise.

            5.04 Joint Indemnification. The amounts to be paid for or on behalf
of any person by the Corporation as indemnification under these By-Laws or
applicable law with


                                      -10-
<PAGE>

respect to any matter shall be reduced by the amount such person is entitled to
receive as indemnification for the same matter from any other source.

            5.05 Benefits to Survive. The indemnification and advancement of
expenses provided by, or granted pursuant to, this section shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the

            5.06 Insurance. The Corporation may, at its own expense, maintain
insurance to protect itself and any Director, officer, employee or agent of the
Corporation, or another corporation, partnership, joint venture, trust or other

change of government in the nation, state, or similar political entity in which
a stockholder or director is then present, or if such person shall become
physically or mentally incapacitated or shall disappear, as a result of which a
quorum of stockholders or directors cannot be readily convened or communicated
with, for


                                      -11-

by any member thereof in the manner otherwise provided for in these By-Laws;

all Directors, shall fill vacancies in the Executive Committee, but during the
temporary absence of a member of the Executive Committee, the remaining members
of the Committee may appoint a member of the board of Directors to act in his
place. The Executive Committee may fix its own rules of proceeding, and shall
meet at such times, in such places, and upon such notice as may be provided by
such rules or by resolution of the Board of Directors. The presence of a
majority of the members of the Executive Committee shall constitute a quorum for
the transaction of business. The affirmative vote of a majority of the members
of the Committee


                                      -6-
<PAGE>

present at a meeting shall be necessary for the adoption of any resolution. The
Executive Committee shall have such powers, authority and duties as may properly
be assigned to it by the Board of Directors. Unless the Board of Directors
otherwise directs, during the intervals between the meetings of the Board of
Directors, the Executive Committee shall possess and may exercise all of the
powers of the Board of Directors in the management of the business and affairs
of the Corporation, except the power to declare dividends, issue stock or to
approve and recommend to stockholders any action requiring stockholder approval.
The Executive Committee shall exercise such powers in a manner which it shall
deem in the best interests of the Corporation in all cases in which specific
directions shall not have been given by the Board of Directors. All actions by
the Executive Committee shall be reported to the Board of Directors at its
meeting next succeeding such action.

            3.02 Other Committees. The Board of Directors may designate one or
more additional committees consisting of one or more Directors which shall have
such powers, authority and duties as may properly be assigned to them by the
Board of Directors. A majority of all Directors shall fill any vacancies
existing in any such committees, but during the temporary absence of any member
of any such committee, the remaining members of the committee may appoint a
member of the Board of Directors to act in his place. Any such committee
appointed by the Board of Directors may fix its own rules of proceedings and
shall meet at such time and place and upon such notice as may be provided by
such rules or by resolution of the Board of Directors. All actions by any such
committee shall be reported to the Board of Directors at its meeting next

Directors may from time to time determine. Officers shall be elected at each
annual meeting of the Board of Directors. Each officer shall serve at the

Directors as set forth in these Bylaws shall not invalidate any action taken by
an officer of the Corporation who has been duly elected and not replaced by the

then in the order of their election) shall perform the duties of the President
and, when so acting, shall have all the powers of and be subject to all the
restrictions upon the President. The Vice-Presidents shall perform such other
duties and have such powers as the Board of Directors or the President may from
time to time prescribe.

Assistant Secretary, or if there be more than one, the Assistant Secretaries in
the order determined by the Board of Directors (or if there be no such
determination, then in the order of their election) shall, in the absence of the
Secretary or in the event of his inability or refusal to act, perform the duties
and exercise the powers of the Secretary and shall perform such other duties and

SECTION 5. INDEMNIFICATION

            5.01 General Right to Indemnification. Every person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or


                                      -9-
<PAGE>

proceeding, whether civil, criminal, administrative or investigative, including
any action by or in the right of the Corporation, by reason of the fact that he
is or was a director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, including in any capacity with respect to an employee benefit plan,
shall be indemnified by the Corporation against any and all liability, expenses
(including attorney's fees), judgments and losses actually and reasonably
incurred by him in connection with any such action, suit or proceeding to the
fullest extent permitted by the Delaware General Corporation Law, as the same
exists or may hereafter be amended (but, in the case of any such amendment, only
to the extent that such amendment permits the Corporation to provide broader
indemnification rights than permitted by such law prior to such amendment). Such
indemnification shall continue as to a person who has ceased to be a director,
officer, employee or agent of the Corporation and shall inure to the benefit of
his heirs, executors and administrators.

            5.02 Advance of Expenses. The Corporation shall have the right, but
not the obligation, to pay expenses incurred by an officer or Director in
defending a civil or criminal action, suit, or proceeding in advance of the
final disposition of such action, suit, or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Section 5. Such expenses incurred by other
employees and agents may also be so paid upon such terms and conditions, if any,
as the Board of Directors deems appropriate.

<PAGE>

            5.03 Non-Exclusivity. The right to indemnification and payment of
expenses provided in Section 5 shall not be deemed to be exclusive of any other
rights to which the person seeking indemnification or payment of expenses may be
entitled under these By-Laws or any agreement by or with the Corporation, by
vote of stockholders or disinterested directors of the Corporation, or
otherwise.

            5.04 Joint Indemnification. The amounts to be paid for or on behalf
of any person by the Corporation as indemnification under these By-Laws or
applicable law with respect to any matter shall be reduced by the amount such
person is entitled to receive as indemnification for the same matter from any
other source.

            5.05 Benefits to Survive. The indemnification and advancement of
expenses provided by, or granted pursuant to, this section shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such a person.

            5.06 Insurance. The Corporation may, at its own expense, maintain
insurance to protect itself and any Director, officer, employee or agent of the
Corporation, or another corporation, partnership, joint venture, trust or other
enterprise against any liability, expense, judgment or loss, whether or not the
Corporation would have the power to indemnify such person against such
liability, expense, judgment, fine or loss under the Delaware General
Corporation Law.

                                     OFFICES

      Section 1. The registered office shall be in the City of Wilmington,
County of New Castle, State of Delaware.

      Section 2. The Corporation may also have offices at such other places both
within and without the State of Delaware as the Board of Directors may from time
to time determine or the business of the Corporation may require.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

      Section 1. Meetings of stockholders shall be held at any place within or
outside the State of Delaware designated by the Board of Directors. In the
absence of any such designation, stockholders' meetings shall be held at the
principal executive office of the Corporation.

      Section 2. The annual meeting of stockholders shall be held each year on a
date and a time designated by the Board of Directors. At each annual meeting
directors shall be elected and any other proper business may be transacted.

      Section 3. A majority of the stock issued and outstanding and entitled to
vote at any meeting of stockholders, the holders of which are present in person
or represented by proxy, shall constitute a quorum for the transaction of
business except as otherwise provided by law, by the Certificate of
Incorporation, or by these By-Laws. A quorum, once established, shall not be
broken by the withdrawal of enough votes to leave less than a quorum and the
votes


                                       1
<PAGE>

present may continue to transact business until adjournment. If, however, such
quorum shall not be present or represented at any meeting of the stockholders, a
majority of the voting stock represented in person or by proxy may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented. At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
notified. If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote thereat.

      Section 4. When a quorum is present at any meeting, the vote of the
holders of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the statutes, or
the Certificate of Incorporation, or these By-Laws, a different vote is required
in which case such express provision shall govern and control the decision of
such question.

      Section 5. At each meeting of the stockholders, each stockholder having
the right to vote may vote in person or may authorize another person or persons
to act for him by proxy appointed by an instrument in writing subscribed by such
stockholder and bearing a date not more than three years prior


                                       2
<PAGE>

to said meeting, unless said instrument provides for a longer period. All
proxies must be filed with the Secretary of the Corporation at the beginning of
each meeting in order to be counted in any vote at the meeting. Each stockholder
shall have one vote for each share of stock having voting power, registered in
his name on the books of the Corporation on the record date set by the Board of
Directors as provided in Article V, Section 6 hereof. All elections shall be had
and all questions decided by a plurality vote.

      Section 6. Special meetings of the stockholders, for any purpose, or
purposes, unless otherwise prescribed by statute or by the Certificate of
Incorporation, may be called by the President and shall be called by the
President or the Secretary at the request in writing of a majority of the Board
of Directors, or at the request in writing of stockholders owning a majority in
amount of the entire capital stock of the Corporation, issued and outstanding,
and entitled to vote. Such request shall state the purpose or purposes of the
proposed meeting. Business transacted at any special meeting of stockholders
shall be limited to the purposes stated in the notice.

      Section 7. Whenever stockholders are required or permitted to take any
action at a meeting, a written notice of the meeting shall be given which notice
shall state the place, date and hour of the meeting, and, in the case of a
special meeting, the purpose or purposes for which the meeting is called. The
written notice of any meeting shall be given to


                                       3
<PAGE>

each stockholder entitled to vote at such meeting not less than ten nor more
than sixty days before the date of the meeting. If mailed, notice is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the Corporation.

      Section 8. The officer who has charge of the stock ledger of the
Corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

      Section 9. Unless otherwise provided in the Certificate of Incorporation,
any action required to be taken at any annual or special meeting of stockholders
of the Corporation, or any action which may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent


                                       4
<PAGE>

in writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

                                   ARTICLE III

                                    DIRECTORS

      Section 1. The number of directors which shall constitute the whole Board
shall be not less than one (1) and not more than five (5). The exact number of
directors shall be determined by resolution of the Board, and the initial number
of directors shall be one (1). The directors need not be stockholders. The
directors shall be elected at the annual meeting of the stockholders, except as
provided in Section 2 of this Article, and each director elected shall hold
office until his successor is elected and qualified; provided, however, that
unless otherwise restricted by the Certificate of Incorporation or by law, any
director or the entire Board of Directors may be removed, either with or without
cause, from the Board of Directors at any meeting of stockholders by a majority
of the stock represented and entitled to vote thereat.

      Section 2. Vacancies on the Board of Directors by reason of death,
resignation, retirement, disqualification, removal from office, or otherwise,
and newly created


                                        5
<PAGE>

directorships resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office, although less than
a quorum, or by a sole remaining director. The directors so chosen shall hold
office until the next annual election of directors and until their successors
are duly elected and shall qualify, unless sooner replaced by a vote of the
shareholders. If there are no directors in office, then an election of directors
may be held in the manner provided by statute. If, at the time of filling any
vacancy or any newly created directorship, the directors then in office shall
constitute less than a majority of the whole Board (as constituted immediately
prior to any such increase), the Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent of the total number of
the shares at the time outstanding having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors then
in office.

      Section 3. The property and business of the Corporation shall be managed
by or under the direction of its Board of Directors. In addition to the powers
and authorities by these By-Laws expressly conferred upon them, the Board may
exercise all such powers of the Corporation and do all such lawful acts and
things as are not by statute or by the Certificate of Incorporation or by these
By-Laws directed or required to be exercised or done by the stockholders.


                                       6
<PAGE>

      Section 4. The directors may hold their meetings and have one or more
offices, and keep the books of the Corporation outside of the State of Delaware.

      Section 5. Regular meetings of the Board of Directors may be held without
notice at such time and place as shall from time to time be determined by the
Board.

      Section 6. Special meetings of the Board of Directors may be called by the
President on forty-eight hours' notice to each director, either personally or by
mail or by telegram; special meetings shall be called by the President or the
Secretary in like manner and on like notice on the written request of two
directors.

      Section 7. At all meetings of the Board of Directors a majority of the
authorized number of directors shall be necessary and sufficient to constitute a
quorum for the transaction of business, and the vote of a majority of the
directors present at any meeting at which there is a quorum, shall be the act of
the Board of Directors, except as may be otherwise specifically provided by
statute, by the Certificate of Incorporation or by these By-Laws. If a quorum
shall not be present at any meeting of the Board of Directors, the directors
present thereat may adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present. If only one
director is authorized, such sole director shall constitute a quorum. At any
meeting, a director shall have the right to be accompanied by counsel


                                        7
<PAGE>

provided that such counsel shall agree to any confidentiality restrictions
reasonably imposed by the Corporation.

      Section 8. Unless otherwise restricted by the Certificate of Incorporation
or these By-Laws, any action required or permitted to be taken at any meeting of
the Board of Directors or of any committee thereof may be taken without a
meeting, if all members of the Board or committee, as the case may be, consent

                               SPD HOLDINGS, INC.

                                    ARTICLE I

                         Shareholders' Meetings; Voting

            Section 1.1. Annual Meetings. An annual meeting of shareholders
shall be held for the election of directors on the first Monday in May of each
year, if not a legal holiday, and, if a legal holiday, then on the next day not
a legal holiday, at 10:00 o'clock in the forenoon at such time and place either
within or without the State of Delaware as may be designated by the Board of
Directors from time to time. Any other proper business may be transacted at the
annual meeting.

            Section 1.2. Special Meetings. Special meetings of shareholders may
be called at any time by the Chairman of the Board, the President, the Board of
Directors, or as provided in Section 2.2, to be held at such date, time and
place either within or without the State of Delaware as may be stated in the
notice of the meeting. A special meeting of shareholders shall be called by the
Secretary upon the written request, stating the purpose of the meeting, of
shareholders who together own of record at least ten percent (10%) of the
outstanding shares of stock entitled to vote at such meeting.

            Section 1.3. Notice of Meetings. Whenever shareholders are required
or permitted to take any action at a meeting, a written notice of the meeting
shall be given which shall state the place, date and hour of the meeting, and,
in the case of a special meeting, the purpose or purposes for which the meeting
is called. Unless otherwise provided by law, the written notice of any meeting
shall be given not less than ten nor more than sixty days before the date of the
meeting to each shareholder entitled to vote at such meeting. If mailed, such
notice shall be deemed to be given when deposited in the United States mail,
postage prepaid, directed to the shareholder at his address as it appears on the
records of the Corporation. The Corporation shall, at the written request of any
shareholder, cause such notice to such shareholder to be confirmed to such other
address and/or by such other means as such shareholder may reasonably request,
provided that if such written request is received after the date any such notice
is mailed, such request shall be elective for subsequent notices only.

            Section 1.4. Adjournments. Any meeting of shareholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the Corporation may
<PAGE>

transact any business which might have been transacted at the original meeting.
If the adjournment is for more than thirty days, or if after the adjournment a
new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each shareholder of record entitled to vote at the
meeting.

            Section 1.5. Quorum. At each meeting of shareholders, except where
otherwise provided by law or the certificate of incorporation or these by-laws,
the holders of a majority of the outstanding shares of each class of stock
entitled to vote at the meeting, present in person or represented by proxy,
shall constitute a quorum. With respect to any matter on which shareholders vote
separately as a class, the holders of a majority of the outstanding shares of
such class shall constitute a quorum for a meeting with respect to such matter.
Two or more classes or series of stock shall be considered a single class for
purposes of determining existence of a quorum for any matter to be acted on if
the holders thereof are entitled or required to vote together as a single class
at the meeting on such matter. In the absence of a quorum the shareholders so
present may, by majority vote, adjourn the meeting from time to time in the
manner provided by Section 1.4 of these by-laws until a quorum shall attend.

            Section 1.6. Organization. Meetings of shareholders shall be
presided over by the Chairman of the Board, or in his absence by the President,
or in his absence by a Vice President, or in the absence of the foregoing
persons by a chairman designated by the Board of Directors, or in the absence of
such designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the chairman of the meeting may
appoint any person to act as secretary of the meeting.

            Section 1.7. Voting; Proxies. Unless otherwise provided in the
certificate of incorporation, each shareholder entitled to vote at any meeting
of shareholders shall be entitled to one vote for each share of stock held by
him which has voting power upon the matter in question. Each shareholder
entitled to vote at a meeting of shareholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three years from its date, unless the proxy provides for a longer period.
A duly executed proxy shall be irrevocable if it states that it is irrevocable
and if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power. A shareholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy or another duly executed proxy bearing
a later date with the Secretary of the Corporation. Voting at meetings of
shareholders need not be by written ballot and need not be conducted by
inspectors unless the holders of a majority of the outstanding shares of any
class of stock entitled to vote thereon present in person or by proxy at such
meeting shall so determine. At all meetings of shareholders for the election of
directors, such election and all other elections and questions shall, unless
otherwise provided by law or by the certificate of incorporation or these
by-laws, be decided by the vote of the holders of a majority of the outstanding
shares of all classes of stock entitled to vote thereon present in person or by
proxy at the meeting, voting as a single class.

            Section 1.8. Fixing Date for Determination of Shareholders of
Record. In order that the Corporation may determine the shareholders entitled to
notice of or to vote at any meeting of shareholders or any adjournment thereof,
or to express consent to corporate action in writing without a meeting, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix, in advance, a record date, which shall not be
more than sixty nor less than ten days before the date of such meeting, nor more
than sixty days prior to any other action. If no record date is fixed: (1) the
record date for determining shareholders entitled to notice of or to vote at a
meeting of shareholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held; (2) the record date for determining shareholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the Board is necessary, shall be the day on which the first written consent
is expressed; and (3) the record date for determining shareholders for any other
purpose shall be at the close of business on the day on which the Board adopts
the resolution relating thereto. A determination of shareholders of record
entitled to notice of or to vote at a meeting of shareholders shall apply to any
adjournment of the meeting; provided, however, that the Board may fix a new
record date for the adjourned meeting.

            Section 1.9. List of Shareholders Entitled to Vote. The Secretary
shall prepare and make, at least ten days before every meeting of shareholders,
a complete list of the shareholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each shareholder and the number
of shares registered in the name of each shareholder. Such list shall be open to
the examination of any shareholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any shareholder who is present.

            Section 1.10. Consent of Shareholders in Lieu of Meeting. To the
extent provided by any statute at the time in force, whenever the vote of
shareholders at a meeting thereof is required or permitted to be taken for or in
connection with any corporate action, by any statute, by the certificate of
incorporation or by these by-laws, the meeting and prior notice thereof and vote
of shareholders may be dispensed with if the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted shall consent in writing to such corporate action without
a meeting by less than unanimous written consent and notice thereof shall be
given to those shareholders who have not consented in writing.

            Section 2.1. Powers; Number; Qualifications. The business and
affairs of the Corporation shall be managed by or under the direction of the
Board of Directors, except as may be otherwise provided by law or in the
certificate of incorporation. The number of Directors which shall constitute the
whole Board of Directors shall not be less than one (1) nor more than eight (8).
Within such limits, the number of directors may be fixed from time to time by
vote of the shareholders or of the Board of Directors, at any regular or special
meeting, subject to the provisions of the certificate of incorporation.

            Section 2.2. Election; Term of Office; Resignation; Removal;
Vacancies; Special Elections. Except as otherwise provided in this Section 2.2,
the directors shall be elected annually at the annual meeting of the
shareholders. Each director (whenever elected) shall hold office until the

elect directors next succeeding his election and until his successor is elected
and qualified or until his earlier resignation or removal, except as provided in
the certificate of incorporation. Any director may resign at any time upon
written notice to the Board of Directors or to the Chairman of the Board or to
the President of the Corporation. Such resignation shall take effect at the time
specified therein, and unless otherwise specified therein no acceptance of such
resignation shall be necessary to make it effective. Any director may be removed
with or without cause at any time upon the affirmative vote of the holders of a
majority of the outstanding shares of stock of the Corporation entitled to vote
for the election of such director, given at a special meeting of such
shareholders called for the purpose. If any vacancies shall occur in the Board
of Directors, by reason of death, resignation, removal or otherwise, or if the
authorized number of directors shall be increased, the directors then in office
shall continue to act, and such vacancies may be filled by a majority of the
directors then in office, though less than a quorum; provided, however, that
whenever the holders of any class or classes of stock or series thereof are
entitled to elect one or more directors by the provisions of the certificate of
incorporation, vacancies and newly created directorships of such class or
classes or series shall be filled by a majority of the directors elected by such
class or classes or series thereof then in office though less than a quorum or
by a sole remaining director so elected. Any such vacancies or newly created
directorships may also be filled upon the affirmative vote of the holders of a
majority of the outstanding shares of stock of the Corporation entitled to vote
for the election of directors, given at a special meeting of the shareholders
called for the purpose.

            Section 2.3. Regular Meetings. Regular meetings of the Board of

Delaware whenever called by the Chairman of the Board, by the President or by
any two directors. Reasonable notice thereof shall be given by the person or
persons calling the meeting.

            Section 2.5. Telephonic Meetings Permitted. Unless otherwise
restricted by the certificate of incorporation or these by-laws, any member of
the Board of Directors, or any committee designated by the Board, may
participate in a meeting of the Board or of such committee, as the case may be,
by means of a conference telephone or similar communications equipment by means
of which all persons participating in the meeting can hear each other, and
participation in a meeting pursuant to this by-law shall constitute presence in
person at such meeting.

            Section 2.6. Quorum; Vote Required for Action. At all meetings of
the Board of Directors the presence of a majority of the total number of
directors shall constitute a quorum for the transaction of business. The vote of
at least a majority of the directors present at any meeting at which a quorum is
present shall be necessary to constitute and shall be the act of the Board
unless the certificate of incorporation or these by-laws shall otherwise
provide. In case at any meeting of the Board a quorum shall not be present, the
members of the Board present may adjourn the meeting from time to time until a
quorum shall attend.

            Section 2.7. Organization. Meetings of the Board of Directors shall
be presided over by the Chairman of the Board, or in his absence by the
President, or in their absence by a chairman chosen at the meeting. The
Secretary shall act as secretary of the meeting, but in his absence the chairman
of the meeting may appoint any person to act as secretary of the meeting.

            Section 2.8. Action by Directors Without a Meeting. Unless otherwise
restricted by the certificate of incorporation or these by-laws, any action
required or permitted to be taken at any meeting of the Board of Directors, or
of any committee thereof, may be taken without a meeting if all members of the
Board or such committee, as the case may be, consents thereto in writing, and
the writing or writings an flied with the minutes of proceedings of the Board or
committee.

                                   ARTICLE III

                                   Committees

passed by a majority of the total number of directors, designate one or more
committees, each committee to consist of one or more of the directors of the
Corporation. Any such committee, to the extent provided in the resolution of the
Board, and unless otherwise restricted by the certificate of incorporation or
these by-laws, shall have and may exercise all


                                       -5-

the powers and authority of the Board in the management of the business and
affairs of the Corporation, to the full extent permitted by law.

            Section 3.2. Committee Rules. Unless the Board of Directors
otherwise provides, each committee designated by the Board may adopt, amend and
repeal rules for the conduct of its business. In the absence of a provision by
the Board or a provision in the rules of such committee to the contrary, the
entire authorized number of members of such committee shall constitute a quorum
for the transaction of business, the vote of all such members present at a
meeting shall be the act of such committee, and in other respects each committee
shall conduct its business pursuant to Article II of these by-laws.

                                   ARTICLE IV

removal. Any officer may resign at any time upon written notice to the Board or
to the President of the Corporation. Such resignation shall take effect at the
time specified therein, and unless otherwise specified therein no acceptance of
such resignation shall be necessary to make it effective. The Board may remove
any officer with or without cause at any time, provided that such action by the
Board shall require the vote of a majority of the whole Board. Any such removal
shall be without prejudice to the contractual rights of such officer, if any,
with the Corporation, but the election of an officer shall not of itself create
contractual rights. Any vacancy occurring in any office of the Corporation by
death, resignation, removal or otherwise shall or may be filled for the
unexpired portion of the term by the Board at any regular or special meeting in
the manner provided in Section 4.1 for election of officers following the annual

owned by him in the Corporation. If such certificate is manually signed by one

she is the legal representative, is or was a director, officer, employee or
agent of the Corporation or any predecessor of the Corporation, or serves or
served any other enterprise as a director, officer, employee or agent at the
request of the Corporation or any predecessor of the Corporation.

            The Corporation shall pay any expenses reasonably incurred by a
director or officer in defending a civil or criminal action, suit or proceeding
in advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such director or officer to repay
such amount if it shall ultimately be determined that he or she is not entitled
to be indemnified by the Corporation under this Article or otherwise. The
Corporation may, by action of its Board of Directors, provide for the payment of
such expenses incurred by employees and agents of the Corporation as it deems
appropriate.

            The rights conferred on any person under this Article shall not be
deemed exclusive of any other rights that such person may have or hereafter
acquire under any statute, provision of the Corporation's Certificate of
Incorporation, by-law, agreement, vote of shareholders or disinterested
directors or otherwise. All tights to indemnification and to the advancement of
expenses under this Article shall be deemed to be provided by a contract between
the Corporation and the director, officer, employee or agent who serves in such
capacity at any time while these By-Laws and any other relevant provisions of
the Delaware General Corporation Law and any other applicable law, if any, are
in effect. Any repeal or modification thereof shall not affect any rights or
obligations then existing.

            For purposes of this Article, references to the "Corporation" shall
be deemed to include any subsidiary of the Corporation now or hereafter
organized under the laws of the State of Delaware.

L-3 Communications Corporation
600 Third Avenue, 34th Floor
New York, NY  10016

Ladies and Gentlemen:

                  We have acted as counsel to L-3 Communications Corporation, a
Delaware corporation (the "Company"), and to Hygienetics Environmental Services,
Inc., a Delaware corporation, L-3 Communications ILEX Systems, Inc., a Delaware
corporation, Southern California Microwave, a California corporation, L-3
Communications SPD Technologies, Inc., a Delaware corporation, L-3
Communications ESSCO, Inc., a Delaware corporation, L-3 Communications Storm
Control Systems, Inc., a California corporation, L-3 Communications DBS
Microwave, a California corporation, SPD Electrical Systems, Inc., a Delaware
corporation, SPD Switchgear Inc., a Delaware corporation, Pac Ord Inc., a
Delaware corporation, Henschel Inc., a Delaware corporation, Power Paragon,
Inc., a Delaware corporation, and SPD Holdings, Inc., a Delaware corporation
(individually, a "Guarantor" and collectively, the "Guarantors"), in connection
with the Registration Statement on Form S-4 (the "Registration Statement") filed
by the Company and the Guarantors with the Securities and Exchange Commission
(the "Commission") under the Securities Act of 1933, as amended, relating to the
issuance by the Company of $200,000,000 aggregate principal amount of Series B
8% Senior Subordinated Notes Due



<PAGE>






2008 (the "Exchange Notes") and the issuance by the Guarantors of guarantees
(the "Guarantees"), to be indorsed by the Guarantors on the Exchange Notes. The
Exchange Notes and the Guarantees will be issued under an indenture (the
"Indenture") among the Company, the Guarantors and the Bank of New York, as
Trustee. The Exchange Notes will be offered by the Company in exchange for
$200,000,000 aggregate principal amount of its outstanding 8% Senior
Subordinated Notes due 2008 (the "Notes").

                  We have examined the Registration Statement and the Indenture,
which has been filed with the Commission as an exhibit to the Registration
Statement. We also have examined the originals, or duplicates or certified or
conformed copies, of such records, agreements, instruments and other documents
and have made such other and further investigations as we have deemed relevant
and necessary in connection with the opinions expressed herein. As to questions
of fact material to this opinion, we have relied upon certificates of public
officials and of officers and representatives of the Company and the Guarantors.

                  In such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the due incorporation and
valid existence of the Guarantors, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as duplicates or certified or conformed copies, and the
authenticity of the originals of such latter documents.

                  Based upon the foregoing, and subject to the qualifications
and limitations stated herein, we are of the opinion that:



                                        2

<PAGE>






                  1. Assuming the Indenture has been duly authorized and validly
         executed and delivered by the parties thereto, when (a) the Board of
         Directors of the Company, a duly constituted and acting committee of
         such Board or duly authorized officers of the Company has or have taken
         all necessary corporate action to approve the issuance and terms of the
         Exchange Notes, the terms of the exchange and related matters and (b)
         the Exchange Notes have been duly executed, authenticated, issued and
         delivered in accordance with the provisions of the Indenture upon the
         exchange, the Exchange Notes will constitute valid and legally binding
         obligations of the Company enforceable against the Company in
         accordance with their terms.

                  2. Assuming the Indenture has been duly authorized and validly
         executed and delivered by the parties thereto, when (a) the Board of
         Directors of each Guarantor, a duly constituted and acting committee of
         each such Board or duly authorized officers of each Guarantor have
         taken all necessary corporate action to approve the issuance and terms
         of the Guarantees and related matters, (b) the Exchange Notes have been
         duly executed, authenticated, issued and delivered in accordance with
         the provisions of the Indenture upon the exchange and (c) the
         Guarantees have been duly indorsed on the Exchange Notes, the
         Guarantees will constitute valid and legally binding obligations of the
         Guarantors enforceable against the Guarantors in accordance with their
         terms.

                  Our opinion set forth above is subject to the effects of (i)
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, (ii)
general equitable principles (whether


                                        3

<PAGE>





considered in a proceeding in equity or at law) and (iii) an implied covenant of
good faith and fair dealing.

                  We are members of the Bar of the State of New York and we do
not express any opinion herein concerning any law other than the law of the
State of New York, the federal law of the United States and the Delaware General
Corporation Law.

                  We hereby consent to the filing of this opinion letter as
Exhibit 5 to the Registration Statement and to the use of our name under the
caption "Legal Matters" in the Prospectus included in the Registration
Statement.

                                                  Very truly yours, 
                                                  /s/ Simpson Thacher & Bartlett
                                                  SIMPSON THACHER & BARTLETT

multiples thereof.

                  The terms and provisions contained in the Notes shall
constitute, and are hereby expressly made, a part of this Indenture and the
Company and the Trustee, by their execution and delivery of this Indenture,

form of Exhibit A attached hereto (including the Global Note Legend and the

Interests in the Global Note" attached thereto). Each Global Note shall
represent such of the outstanding Notes as shall be specified therein and each

principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented
thereby shall be made by the Trustee or the Note Custodian, at the direction of
the Trustee, in accordance with instructions given by the Holder thereof as

                  If an Officer whose signature is on a Note no longer holds
that office at the time a Note is authenticated, the Note shall nevertheless be
valid.

                  A Note shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

Registrar.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal, premium, or interest on the Notes, and will notify the
Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee. Upon payment over to the Trustee,
the Paying Agent (if other than the Company or a Subsidiary) shall have no
further liability for the money. If the Company or a Subsidiary acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent. Upon any bankruptcy or
reorganization proceedings relating to the Company, the Trustee shall serve as
Paying Agent for the Notes.

SECTION 2.05. HOLDER 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 all Holders and shall otherwise comply with TIA ss. 312(a). If the
Trustee is not the Registrar, the Company shall furnish to the Trustee at least
five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Company shall otherwise comply with TIA ss. 312(a).

SECTION 2.06. TRANSFER AND EXCHANGE.

                  (a) Transfer and Exchange of Global Notes. A Global Note may
not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Notes will be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 120 days after the date of
such notice from the Depositary or (ii) the Company in its sole discretion
determines that

                                      20
<PAGE>


the Global Notes (in whole but not in part) should be exchanged for Definitive
Notes and delivers a written notice to such effect to the Trustee. Upon the
occurrence of either of the preceding events in (i) or (ii) above, Definitive
Notes shall be issued in such names as the Depositary shall instruct the
Trustee. Global Notes also may be exchanged or replaced, in whole or in part,
as provided in Sections 2.07 and 2.11 hereof. Every Note authenticated and made
available for delivery in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to Section 2.07 or 2.11 hereof, shall be
authenticated and made available for delivery in the form of, and shall be, a
Global Note. A Global Note may not be exchanged for another Note other than as
provided in this Section 2.06(a), however beneficial interests in a Global Note
may be transferred and exchanged as provided in Section 2.06(b), (c) or (f)
hereof.

                  (b) Transfer and Exchange of Beneficial Interests in the
Global Notes. The transfer and exchange of beneficial interests in the Global
Notes shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the procedures of the Depositary therefor. The
Trustee shall have no obligation to ascertain the Depositary's compliance with
any such restrictions on transfer. Transfers of beneficial interests in the
Global Notes also shall require compliance with either subparagraph (i) or (ii)
below, as applicable, as well as one or more of the other following
subparagraphs as applicable:

                  (i) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Unrestricted Global Note may be
         transferred only to Persons who take delivery thereof in the form of a
         beneficial interest in an Unrestricted Global Note. No written orders
         or instructions shall be required to be delivered to the Registrar to
         effect the transfers described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial
         Interests in Global Notes. In connection with all transfers and
         exchanges of beneficial interests (other than transfers of beneficial
         interests in a Global Note to Persons who take delivery thereof in the
         form of a beneficial interest in the same Global Note), the transferor
         of such beneficial interest must deliver to the Registrar either (A)
         (1) a written order from a Participant or an Indirect Participant
         given to the Depositary in accordance with the Applicable Procedures
         directing the Depositary to credit or cause to be credited a
         beneficial interest in the specified Global Note in an amount equal to
         the beneficial interest to be transferred or exchanged and (2)
         instructions given in accordance with the Applicable Procedures
         containing information regarding the Participant account to be
         credited with such increase or (B) (1) a written order from a
         Participant or an Indirect Participant given to the Depositary in
         accordance with the Applicable Procedures directing the Depositary to
         cause to be issued a Definitive Note in an amount equal to the
         beneficial interest to be transferred or exchanged and (2)
         instructions given by the Depositary to the Registrar containing
         information regarding the Person in whose name such Definitive Note
         shall be registered to effect the transfer or exchange referred to in
         (1) above. Upon satisfaction of all of the requirements for transfer
         or exchange of beneficial interests in Global Notes contained in this
         Indenture, the Notes and otherwise 


                                      21
<PAGE>

         applicable under the Securities Act, the Trustee shall adjust
         the principal amount of the relevant Global Note(s) pursuant
         to Section 2.06(h) hereof.

                  (c) Transfer or Exchange of Beneficial Interests for 
         Definitive Notes.

                  (iii) If any holder of a beneficial interest in an
         Unrestricted Global Note proposes to exchange such beneficial interest
         for a Definitive Note or to transfer such beneficial interest to a
         Person who takes delivery thereof in the form of a Definitive Note,
         then, upon satisfaction of the conditions set forth in Section
         2.06(b)(ii), the Trustee shall cause the aggregate principal amount of
         the applicable Global Note to be reduced accordingly pursuant to
         Section 2.06(h) hereof, and the Company shall execute and the Trustee
         shall authenticate and deliver to the Person designated in the
         instructions a Definitive Note in the appropriate principal amount.
         Definitive Notes issued in exchange for a beneficial interest pursuant
         to this Section 2.06(c)(iii) shall be registered in such names and in
         such authorized denominations as the holder shall instruct the
         Registrar through instructions from the Depositary and the Participant
         or Indirect Participant. The Trustee shall deliver such Definitive
         Notes to the Persons in whose names such Notes are so registered.

                  (d) Transfer or Exchange of Definitive Notes for 
         Beneficial Interests.

                  (iv) A Holder of Unrestricted Definitive Notes may exchange
         such Notes for a beneficial interest in the Unrestricted Global Note
         or transfer such Definitive Notes to a Person who takes delivery
         thereof in the form of a beneficial interest in the Unrestricted
         Global Note. Upon receipt of a request for such an exchange or
         transfer, the Trustee shall cancel the Unrestricted Definitive Notes
         and increase or cause to be increased the aggregate principal amount
         of the Unrestricted Global Note.

                  If any such exchange or transfer from a Definitive Note to a
beneficial interest is effected pursuant to subparagraphs (i) above at a time
when an Unrestricted Global Note has not yet been issued, the Company shall
issue and, upon receipt of an authentication order in accordance with Section
2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global
Notes in an aggregate principal amount equal to the principal amount of
beneficial interests transferred pursuant to subparagraphs (ii)(B), (ii)(D) or
(iii) above.

                  (e) Transfer and Exchange of Definitive Notes. Upon request
by a Holder of Definitive Notes and such Holder's compliance with the
provisions of this Section 2.06(e), the Registrar shall register the transfer
or exchange of Definitive Notes. Prior to such registration of transfer or
exchange, the requesting Holder shall present or surrender to the Registrar the
Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or
by his attorney, duly authorized in writing. In addition, the requesting Holder
shall provide any additional certifications, documents and information, as
applicable, pursuant to the provisions of this Section 2.06(e).

                                      22
<PAGE>

                  (v) A Holder of Unrestricted Definitive Notes may transfer
         such Notes to a Person who takes delivery thereof in the form of an
         Unrestricted Definitive Note. Upon receipt of a request for such a
         transfer, the Registrar shall register the Unrestricted Definitive
         Notes pursuant to the instructions from the Holder thereof.

                  (f) Legends. The following Global Note Legend shall appear on
the face of all Global Notes issued under this Indenture:

         "THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
         INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE
         BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO
         ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY
         MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.07
         OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT
         NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (III) THIS
         GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT
         TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE
         TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT
         OF THE COMPANY."

                  (g) Cancellation and/or Adjustment of Global Notes. At such
time as all beneficial interests in a particular Global Note have been
exchanged for Definitive Notes or a particular Global Note has been redeemed,
repurchased or canceled in whole and not in part, each such Global Note shall
be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 hereof. At any time prior to such cancellation, if any beneficial
interest in a Global Note is exchanged for or transferred to a Person who will
take delivery thereof in the form of a beneficial interest in another Global
Note or for Definitive Notes, the principal amount of Notes represented by such
Global Note shall be reduced accordingly and an endorsement shall be made on
such Global Note, by the Trustee or by the Depositary at the direction of the
Trustee, to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note
shall be increased accordingly and an endorsement shall be made on such Global
Note, by the Trustee or by the Depositary at the direction of the Trustee, to
reflect such increase.

                  (h) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Global Notes
         and Definitive Notes upon the Company's order or at the Registrar's
         request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Note or to a Holder of a Definitive
         Note for any registration of transfer or 



                                      23
<PAGE>

         exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax or similar governmental
         charge payable in connection therewith (other than any such
         transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 2.10, 3.06, 4.10,
         4.15 and 9.05 hereof).

                  (iii) The Registrar shall not be required to register the
         transfer of or exchange any Note selected for redemption in whole or
         in part, except the unredeemed portion of any Note being redeemed in
         part.

                  (iv) All Global Notes and Definitive Notes issued upon any
         registration of transfer or exchange of Global Notes or Definitive
         Notes shall be the valid obligations of the Company, evidencing the
         same debt, and entitled to the same benefits under this Indenture, as
         the Global Notes or Definitive Notes surrendered upon such
         registration of transfer or exchange.

                  (v) The Company shall not be required (A) to issue, to
         register the transfer of or to exchange Notes during a period
         beginning at the opening of business 15 days before the day of any
         selection of Notes for redemption under Section 3.02 hereof and ending
         at the close of business on the day of selection, (B) to register the
         transfer of or to exchange any Note so selected for redemption in
         whole or in part, except the unredeemed portion of any Note being
         redeemed in part or (C) to register the transfer of or to exchange a
         Note between a record date and the next succeeding Interest Payment
         Date.

                  (vi) Prior to due presentment for the registration of a
         transfer of any Note, the Trustee, any Agent and the Company may deem
         and treat the Person in whose name any Note is registered as the
         absolute owner of such Note for the purpose of receiving payment of
         principal of and interest on such Notes and for all other purposes,
         and none of the Trustee, any Agent or the Company shall be affected by
         notice to the contrary.

                  (vii) The Trustee shall authenticate Global Notes and
         Definitive Notes in accordance with the provisions of Section 2.02
         hereof.

SECTION 2.07. REPLACEMENT NOTES.

                  If any mutilated Note is surrendered to the Trustee, or the
Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the
Trustee, upon the written order of the Company signed by two Officers of the
Company, shall authenticate a replacement Note if the Trustee's requirements
are met. If required by the Trustee or the Company, an indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Trustee and
the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

                                      24
<PAGE>

                  Every replacement Note is an additional obligation of the
Company and shall be entitled to all of the benefits of this Indenture equally
and proportionately with all other Notes duly issued hereunder.

SECTION 2.08. OUTSTANDING NOTES.

                  The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those canceled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Note
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. Except as set forth in Section
2.09 hereof, a Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Note.

                  If a Note is replaced pursuant to Section 2.07 hereof, it
ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Note is held by a bona fide purchaser.

                  If the principal amount of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to
accrue.

                  If the Paying Agent (other than the Company, a Subsidiary or
an Affiliate of any thereof) holds, on a redemption date or maturity date,
money sufficient to pay Notes payable on that date, then on and after that date
such Notes shall be deemed to be no longer outstanding and shall cease to
accrue interest.

SECTION 2.09. TREASURY NOTES.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company,
shall be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that a Trustee knows are so owned
shall be so disregarded.

SECTION 2.10. TEMPORARY NOTES.

                  Until Definitive Notes are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Notes upon a written
order of the Company signed by two Officers of the Company. Temporary Notes
shall be substantially in the form of Definitive Notes but may have variations
that the Company considers appropriate for temporary Notes and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate Definitive Notes in exchange
for temporary Notes.

                  Holders of temporary Notes shall be entitled to all of the
benefits of this Indenture.

                                      25
<PAGE>

SECTION 2.11. CANCELLATION.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee and no one else shall cancel all Notes surrendered for registration
of transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes shall be delivered
to the Company. The Company may not issue new Notes to replace Notes that it
has paid or that have been delivered to the Trustee for cancellation.

SECTION 2.12. DEFAULTED INTEREST.

                  If the Company defaults in a payment of interest on the
Notes, it shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the Persons who
are Holders on a subsequent special record date, in each case at the rate
provided in the Notes and in Section 4.01 hereof. The Company shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on
each Note and the date of the proposed payment. The Company shall fix or cause
to be fixed each such special record date and payment date, provided that no
such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest. At least 15 days before the special
record date, the Company (or, upon the written request of the Company, the
Trustee in the name and at the expense of the Company) shall mail or cause to
be mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

SECTION 2.13. CUSIP NUMBERS.

                  The Company in issuing the Notes may use CUSIP numbers (if
then generally in use), and, if so, the Trustee shall use CUSIP numbers in
notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Notes or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Notes, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company will promptly notify the
Trustee of any change in the CUSIP numbers.

                                   ARTICLE 3.
                           REDEMPTION AND PREPAYMENT

SECTION 3.01. NOTICES TO TRUSTEE.

                  If the Company elects to redeem Notes pursuant to the
optional redemption provisions of Section 3.07 hereof, it shall furnish to the
Trustee, at least 30 days but not more than 60 days before a redemption date,
an Officers' Certificate setting forth (i) the clause of this 


                                      26
<PAGE>


Indenture pursuant to which the redemption shall occur, (ii) the redemption
date, (iii) the principal amount of Notes to be redeemed and (iv) the
redemption price.

SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED.

                  If less than all of the Notes are to be redeemed at any time,
selection of Notes for redemption shall be made by the Trustee in compliance
with the requirements of the principal national securities exchange, if any, on
which the Notes are listed, or, if the Notes are not so listed, on a pro rata
basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided that no Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Notes to be redeemed at its
registered address. Notices of redemption may not be conditional. If any Note
is to be redeemed in part only, the notice of redemption that relates to such
Note shall state the portion of the principal amount thereof to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof shall be
issued in the name of the Holder thereof upon cancellation of the original
Note. Notes called for redemption become due on the date fixed for redemption.
On and after the redemption date, interest ceases to accrue on Notes or
portions of them called for redemption.

                  The Trustee shall promptly notify the Company in writing of
the Notes selected for redemption and, in the case of any Note selected for
partial redemption, the principal amount thereof to be redeemed. Notes and
portions of Notes selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

SECTION 3.03. NOTICE OF REDEMPTION.

                  Subject to the provisions of Section 3.09 hereof, at least 30
days but not more than 60 days before a redemption date, the Company shall mail
or cause to be mailed, by first class mail, a notice of redemption to each
Holder whose Notes are to be redeemed at its registered address.

                  The notice shall identify the Notes to be redeemed (including
CUSIP Numbers, if any) and shall state:

                  (a) the redemption date;

                  (b) the redemption price;

                  (c) if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption
date upon surrender of such Note, a new Note or Notes in principal amount equal
to the unredeemed portion shall be issued upon cancellation of the original
Note;

                                      27
<PAGE>


                  (d) the name and address of the Paying Agent;

                  (e) that Notes called for redemption must be surrendered to
the Paying Agent to collect the redemption price;

                  (f) that, unless the Company defaults in making such
redemption payment, interest on Notes called for redemption ceases to accrue on
and after the redemption date;

                  (g) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the Notes called for redemption are being redeemed;
and

                  (h) that no representation is made as to the correctness or
accuracy of the CUSIP number, if any, listed in such notice or printed on the
Notes.

                  At the Company's request, the Trustee shall give the notice
of redemption in the Company's name and at its expense; provided, however, that
the Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph.

SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

                  Once notice of redemption is mailed in accordance with
Section 3.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date at the redemption price. A notice of redemption
may not be conditional.

SECTION 3.05. DEPOSIT OF REDEMPTION PRICE.

                  Prior to 11:00 a.m. on the Business Day prior to the
redemption date, the Company shall deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption price of and accrued interest on
all Notes to be redeemed on that date. The Trustee or the Paying Agent shall
promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest on, all Notes to be redeemed.

                  If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof.

                  Except as set forth under Sections 4.10 and 4.15, the Company

SECTION 3.09. OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

                  In the event that, pursuant to Section 4.10 hereof, the

(an "Asset Sale Offer"), it shall follow the procedures specified below.

                                      29
<PAGE>

                  The Asset Sale Offer shall remain open for a period of 20
Business Days following its commencement and no longer, except to the extent
that a longer period is required by applicable law (the "Offer Period"). No
later than five Business Days after the termination of the Offer Period (the
"Purchase Date"), the Company shall purchase the principal amount of Notes
required to be purchased pursuant to Section 4.10 hereof (the "Offer Amount")
or, if less than the Offer Amount has been tendered, all Notes tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased shall be
made in the same manner as interest payments are made.

                  If the Purchase Date is on or after an interest record date
and on or before the related interest payment date, any accrued and unpaid
interest shall be paid to the Person in whose name a Note is registered at the
close of business on such record date, and no additional interest shall be
payable to Holders who tender Notes pursuant to the Asset Sale Offer.

                  Upon the commencement of an Asset Sale Offer, the Company
shall send, by first class mail, a notice to the Trustee and each of the
Holders, with a copy to the Trustee. The notice shall contain all instructions
and materials necessary to enable such Holders to tender Notes pursuant to the
Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The
notice, which shall govern the terms of the Asset Sale Offer, shall state:

                  (a) that the Asset Sale Offer is being made pursuant to this
Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale
Offer shall remain open;

                  (b) the Offer Amount, the purchase price and the Purchase
Date;

                  (c) that any Note not tendered or accepted for payment shall
continue to accrete or accrue interest;

                  (d) that, unless the Company defaults in making such payment,
any Note accepted for payment pursuant to the Asset Sale Offer shall cease to
accrete or accrue interest after the Purchase Date;

                  (e) that Holders electing to have a Note purchased pursuant
to an Asset Sale Offer may only elect to have all of such Note purchased and
may not elect to have only a portion of such Note purchased;

                  (f) that Holders electing to have a Note purchased pursuant
to any Asset Sale Offer shall be required to surrender the Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Note
completed, or transfer by book-entry transfer, to the Company, a depositary, if
appointed by the Company, or a Paying Agent at the address specified in the
notice at least three days before the Purchase Date;

                  (g) that Holders shall be entitled to withdraw their election
if the Company, the depositary or the Paying Agent, as the case may be,
receives, not later than the expiration of the Offer Period, a facsimile
transmission or letter setting forth the name of the Holder, the 


                                      30
<PAGE>

principal amount of the Note the Holder delivered for purchase and a statement
that such Holder is withdrawing his election to have such Note purchased;

                  (h) that, if the aggregate principal amount of Notes
surrendered by Holders exceeds the Offer Amount, the Company shall select the
Notes to be purchased on a pro rata basis (with such adjustments as may be
deemed appropriate by the Company so that only Notes in denominations of
$1,000, or integral multiples thereof, shall be purchased); and

                  (i) that Holders whose Notes were purchased only in part
shall be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered (or transferred by book-entry transfer).

                  On or before the Purchase Date, the Company shall, to the
extent lawful, accept for payment, on a pro rata basis to the extent necessary,
the Offer Amount of Notes or portions thereof tendered pursuant to the Asset
Sale Offer, or if less than the Offer Amount has been tendered, all Notes
tendered, and shall deliver to the Trustee an Officers' Certificate stating
that such Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 3.09. The Company, the Depositary or
the Paying Agent, as the case may be, shall promptly (but in any case not later
than five days after the Purchase Date) mail or deliver to each tendering
Holder an amount equal to the purchase price of the Notes tendered by such
Holder and accepted by the Company for purchase, and the Company shall promptly
issue a new Note, and the Trustee, upon written request from the Company shall
authenticate and mail or deliver such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered. Any Note not
so accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company shall publicly announce the results of the Asset Sale
Offer on the Purchase Date.

                  Other than as specifically provided in this Section 3.09, any
purchase pursuant to this Section 3.09 shall be made pursuant to the provisions
of Sections 3.01 through 3.06 hereof.

SECTION 4.01. PAYMENT OF NOTES.

                  The Company shall pay or cause to be paid the principal of,
premium, if any, and interest on the Notes on the dates and in the manner
provided in the Notes. Principal, premium, if any, and interest shall be
considered paid on the date due if the Paying Agent, if other than the Company
or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date
money deposited by the Company in immediately available funds and designated
for and sufficient to pay all principal, premium, if any, and interest then
due.

                  The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal at
the rate equal to 1% per annum in excess of the


                                      31
<PAGE>


then applicable interest rate on the Notes to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY.

                  The Company shall maintain in the Borough of Manhattan, The
City of New York, an office or agency (which may be an office of the Trustee or
an affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may
be served. The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee.

                  The Company may also from time to time designate one or more
other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

                  The Company hereby designates the Corporate Trust Office of
the Trustee as one such office or agency of the Company in accordance with
Section 2.03.

SECTION 4.03. REPORTS.

                  Notwithstanding that the Company may not be subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise
report on an annual and quarterly basis on forms provided for such annual and
quarterly reporting pursuant to rules and regulations promulgated by the SEC,
the Company shall file with the SEC (and provide the Trustee and Holders with
copies thereof), without cost to each Holder, within 15 days after it files
them with the SEC:

comparable form);

                  (d) any other information, documents and other reports which
the Company would be required to file with the SEC if it were subject to
Section 13 or 15(d) of the Exchange Act; provided, however, the Company shall
not be so obligated to file such reports with the SEC if the SEC does not
permit such filing, in which event the Company will make available such
information to prospective purchasers of Notes, in addition to providing such
information to the Trustee and the Holders, in each case within 15 days after
the time the Company would be required to file such information with the SEC,
if it were subject to Sections 13 or 15(d) of the Exchange Act.

                  Subject to the provisions of Article 7, delivery of such
reports, information and documents to the Trustee is for informational purposes
only and the Trustee's receipt of such shall not constitute constructive notice
of any information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

SECTION 4.04. COMPLIANCE CERTIFICATE.

                  (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled
each and every covenant contained in this Indenture and is not in default in
the performance or observance of any of the terms, provisions and conditions of
this Indenture (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which he or she may have
knowledge and what action the Company is taking or proposes to take with
respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action the Company is taking
or proposes to take with respect thereto.

                  (b) So long as not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
year-end financial statements delivered pursuant to Section 4.03(a) above shall
be accompanied by a written statement of the Company's independent public
accountants (who shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial
statements, nothing has come to their attention that would lead them to believe
that the Company has violated any provisions of Article 4 or Article 5 hereof
or, if any such violation has occurred, specifying the nature and period of
existence thereof, it being understood that such accountants shall not be
liable directly or indirectly to any Person for any failure to obtain knowledge
of any such violation.

                                      33
<PAGE>

                  (c) The Company shall, so long as any of the Notes are
outstanding, deliver to the Trustee, as soon as possible and in any event
within five Business Days after any Officer becoming aware of any Default or
Event of Default, an Officers' Certificate specifying such Default or Event of
Default and what action the Company is taking or proposes to take with respect
thereto.

SECTION 4.05. TAXES.

                  The Company shall pay, and shall cause each of its
Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies except such as are contested in good faith and by
appropriate proceedings or where the failure to effect such payment is not
adverse in any material respect to the Holders of the Notes.

SECTION 4.06. [INTENTIONALLY OMITTED]

SECTION 4.07. RESTRICTED PAYMENTS.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any
dividend or make any other payment or distribution on account of the Company's
or any of its Restricted Subsidiaries' Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation
involving the Company) or to the direct or indirect holders of the Company's or
any of its Restricted Subsidiaries' Equity Interests in their capacity as such
(other than (A) dividends or distributions payable in Equity Interests (other
than Disqualified Stock) of the Company or (B) dividends or distributions by a
Restricted Subsidiary so long as, in the case of any dividend or distribution
payable on or in respect of any class or series of securities issued by a
Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, the
Company or a Restricted Subsidiary receives at least its pro rata share of such
dividend or distribution in accordance with its Equity Interests in such class
or series of securities); (ii) purchase, redeem or otherwise acquire or retire
for value (including without limitation, in connection with any merger or
consolidation involving the Company) any Equity Interests of the Company or any
direct or indirect parent of the Company; (iii) make any payment on or with
respect to, or purchase, redeem, defease or otherwise acquire or retire for
value any Indebtedness that is subordinated to the Notes except a payment of
interest or principal at Stated Maturity; or (iv) make any Restricted
Investment (all such payments and other actions set forth in clauses (i)
through (iv) above being collectively referred to as "Restricted Payments"),
unless, at the time of and after giving effect to such Restricted Payment:

                  (a) no Default or Event of Default shall have occurred and 
         be continuing or would occur as a consequence thereof; and

                  (b) the Company would, at the time of such Restricted Payment
         and after giving pro forma effect thereto as if such Restricted
         Payment had been made at the beginning of the applicable four-quarter
         period, have been permitted to incur at least

                                      34
<PAGE>

         $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage
         Ratio test set forth in the first paragraph of Section 4.09; and

                  (c) such Restricted Payment, together with the aggregate
         amount of all other Restricted Payments made by the Company and its
         Restricted Subsidiaries since April 30, 1997 (excluding Restricted
         Payments permitted by clauses (ii) through (vii) of the next
         succeeding paragraph or of the kind contemplated by such clauses that
         were made prior to the date of the Indenture), is less than the sum of
         (i) 50% of the Consolidated Net Income of the Company for the period
         (taken as one accounting period) from July 1, 1997 to the end of the
         Company's most recently ended fiscal quarter for which internal
         financial statements are available at the time of such Restricted
         Payment (or, if such Consolidated Net Income for such period is a
         deficit, less 100% of such deficit), plus (ii) 100% of the aggregate
         net cash proceeds received by the Company since April 30, 1997 from a
         contribution to its common equity capital or the issue or sale of
         Equity Interests of the Company (other than Disqualified Stock) or of
         Disqualified Stock or debt securities of the Company that have been
         converted into such Equity Interests (other than Equity Interests (or
         Disqualified Stock or convertible debt securities) sold to a
         Subsidiary of the Company and other than Disqualified Stock or
         convertible debt securities that have been converted into Disqualified
         Stock), plus (iii) to the extent that any Restricted Investment that
         was made after April 30, 1997 is sold for cash or otherwise liquidated
         or repaid for cash, the amount of cash received in connection
         therewith (or from the sale of Marketable Securities received in
         connection therewith), plus (iv) to the extent not already included in
         such Consolidated Net Income of the Company for such period and
         without duplication, (A) 100% of the aggregate amount of cash received
         as a dividend from an Unrestricted Subsidiary, (B) 100% of the cash
         received upon the sale of Marketable Securities received as a dividend
         from an Unrestricted Subsidiary, and (C) 100% of the net assets of any
         Unrestricted Subsidiary on the date that it becomes a Restricted
         Subsidiary.

                  The foregoing provisions shall not prohibit: (i) the payment
of any dividend within 60 days after the date of declaration thereof, if at
said date of declaration such payment would have complied with the provisions
of this Indenture; (ii) the redemption, repurchase, retirement, defeasance or
other acquisition of any subordinated Indebtedness or Equity Interests of the
Company in exchange for, or out of the net cash proceeds of the substantially
concurrent sale (other than to a Subsidiary of the Company) of, other Equity
Interests of the Company (other than any Disqualified Stock); provided that the
amount of any such net cash proceeds that are utilized for any such redemption,
repurchase, retirement, defeasance or other acquisition shall be excluded from
clause (c) (ii) of the preceding paragraph; (iii) the defeasance, redemption,
repurchase or other acquisition of subordinated Indebtedness (other than
intercompany Indebtedness) in exchange for, or with the net cash proceeds from
an incurrence of, Permitted Refinancing Indebtedness; (iv) the repurchase,
retirement or other acquisition or retirement for value of common Equity
Interests of the Company or Holdings held by any future, present or former
employee, director or consultant of the Company or any Subsidiary or Holdings
issued pursuant to any management equity plan or


                                      35
<PAGE>

stock option plan or any other management or employee benefit plan or
agreement; provided, however, that the aggregate amount of Restricted Payments
made under this clause (iv) does not exceed $1.5 million in any calendar year
and provided further that cancellation of Indebtedness owing to the Company
from members of management of the Company or any of its Restricted Subsidiaries
in connection with a repurchase of Equity Interests of the Company shall not be
deemed to constitute a Restricted Payment for purposes of this covenant or any
other provision of this Indenture; (v) repurchases of Equity Interests deemed
to occur upon exercise of stock options upon surrender of Equity Interests to
pay the exercise price of such options; (vi) payments to Holdings (A) in
amounts equal to the amounts required for Holdings to pay franchise taxes and
other fees required to maintain its legal existence and provide for other
operating costs of up to $500,000 per fiscal year and (B) in amounts equal to
amounts required for Holdings to pay federal, state and local income taxes to
the extent such income taxes are actually due and owing; provided that the
aggregate amount paid under this clause (B) does not exceed the amount that the
Company would be required to pay in respect of the income of the Company and
its Subsidiaries if the Company were a stand alone entity that was not owned by
Holdings; and (vii) other Restricted Payments in an aggregate amount since the
Issue Date not to exceed $20.0 million.

                  The Board of Directors of the Company may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if such designation
would not cause a Default. For purposes of making such determination, all
outstanding Investments by the Company and its Restricted Subsidiaries (except
to the extent repaid in cash) in the Subsidiary so designated shall be deemed
to be Restricted Payments at the time of such designation and shall reduce the
amount available for Restricted Payments under the first paragraph of this
covenant. All such outstanding Investments shall be deemed to constitute
Investments in an amount equal to the fair market value of such Investments at
the time of such designation. Such designation shall only be permitted if such
Restricted Payment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

                  The amount of all Restricted Payments (other than cash) shall
be the fair market value on the date of the Restricted Payment of the asset(s)
or securities proposed to be transferred or issued by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined by the
Board of Directors whose resolution with respect thereto shall be delivered to
the Trustee. Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by Section 4.07 were computed.

SECTION 4.08. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary to (i)(A) pay dividends or make any other
distributions to the Company or any of its Restricted Subsidiaries (1) on its
Capital Stock or (2) with respect to any other interest or participation in, or
measured by, its profits, or (B)


                                      36
<PAGE>

pay any indebtedness owed to the Company or any of its Restricted Subsidiaries,
(ii) make loans or advances to the Company or any of its Restricted
Subsidiaries, or (iii) transfer any of its properties or assets to the Company
or any of its Restricted Subsidiaries, except for such encumbrances or
restrictions existing under or by reason of (A) the provisions of security
agreements that restrict the transfer of assets that are subject to a Lien
created by such security agreements, (B) the provisions of agreements governing
Indebtedness incurred pursuant to clause (v) of the second paragraph of Section
4.09, (C) this Indenture, the Notes, and the 1997 Indenture and the 1997 Notes,

of a Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except to the extent such Indebtedness
was incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties
or assets of any Person, other than the Person, or the property or assets of
the Person, so acquired, provided that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be incurred, (F)
by reason of customary non-assignment provisions in leases entered into in the
ordinary course of business and consistent with past practices, (G) purchase
money obligations for property acquired in the ordinary course of business that
impose restrictions of the nature described in this clause (iii) on the
property so acquired, (H) Permitted Refinancing Indebtedness, provided that the
restrictions contained in the agreements governing such Permitted Refinancing
Indebtedness are no more restrictive than those contained in the agreements
governing the Indebtedness being refinanced, (I) contracts for the sale of
assets, including, without limitation, customary restrictions with respect to a
Subsidiary pursuant to an agreement that has been entered into for the sale or
disposition of all or substantially all of the Capital Stock or assets of such
Subsidiary, (J) agreements relating to secured Indebtedness otherwise permitted
to be incurred pursuant to 4.09 and 4.12 that limit the right of the debtor to
dispose of the assets securing such Indebtedness, (K) restrictions on cash or
other deposits or net worth imposed by customers under contracts entered into
in the ordinary course of business, or (L) customary provisions in joint
venture agreements and other similar agreements entered into in the ordinary
course of business.

SECTION 4.09. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

                  The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (including
Acquired Debt) and that the Company shall not issue any Disqualified Stock and
shall not permit any of its Subsidiaries to issue any shares of preferred
stock; provided, however, that the Company and any Restricted Subsidiary may
incur Indebtedness (including Acquired Debt) or issue shares of preferred stock
if the Fixed Charge Coverage Ratio for the Company's most recently ended four
full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is
incurred or such preferred stock is issued would have been at least 2.0 to 1.0,
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred, or
the preferred stock had been issued, as the case may be, at the beginning of
such four-quarter period.

                  The provisions of the first paragraph of this Section 4.09
shall not apply to the incurrence of any of the following items of Indebtedness
(collectively, "Permitted Debt"):

                  (i) the incurrence by the Company of additional Indebtedness
         under Credit Facilities (and the guarantee thereof by the Guarantors)
         in an aggregate principal amount outstanding pursuant to this clause
         (i) at any one time (with letters of credit being deemed to have a
         principal amount equal to the maximum potential liability of the
         Company and its Restricted Subsidiaries thereunder), including all
         Permitted Refinancing Indebtedness then outstanding incurred to
         refund, refinance or replace any other Indebtedness incurred pursuant
         to this clause (i), not to exceed $375.0 million less the aggregate
         amount of all Net Proceeds of Asset Sales applied to repay any such
         Indebtedness pursuant to Section 4.10;

                  (ii) the incurrence by the Company and its Restricted
         Subsidiaries of the Existing Indebtedness;

                  (iii) the incurrence by the Company and the Guarantors of
         $180.0 million in aggregate principal amount of the Notes and the
         Subsidiary Guarantees thereof;

                  (iv) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness represented by Capital Lease Obligations,
         mortgage financings or purchase money obligations, in each case
         incurred for the purpose of financing all or any part of the purchase
         price or cost of construction or improvement of property, plant or
         equipment used in the business of the Company or such Restricted
         Subsidiary, in an aggregate principal amount, including all Permitted
         Refinancing Indebtedness then outstanding incurred to refund,
         refinance or replace any other Indebtedness incurred pursuant to this
         clause (iv), not to exceed $30.0 million at any time outstanding;

                  (v) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness in connection with the acquisition of
         assets or a new Restricted Subsidiary; provided that such Indebtedness
         was incurred by the prior owner of such assets or such Restricted
         Subsidiary prior to such acquisition by the Company or one of its
         Restricted Subsidiaries and was not incurred in connection with, or in
         contemplation of, such acquisition by the Company or one of its
         Restricted Subsidiaries; and provided further that the principal
         amount (or accreted value, as applicable) of such Indebtedness,
         together with any other outstanding Indebtedness incurred pursuant to
         this clause (v), does not exceed $10.0 million;

                  (vi) the incurrence by the Company or any of its Restricted
         Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or
         the net proceeds of which are used to refund, refinance or replace,
         Indebtedness that was permitted by this Indenture to be incurred
         (other than intercompany Indebtedness or Indebtedness incurred
         pursuant to clause (i) above);

                                      38
<PAGE>

                  (vii) Indebtedness incurred by the Company or any of its
         Restricted Subsidiaries constituting reimbursement obligations with
         respect to letters of credit issued in the ordinary course of business
         in respect of workers' compensation claims or self-insurance, or other
         Indebtedness with respect to reimbursement type obligations regarding
         workers' compensation claims; provided, however, that upon the drawing
         of such letters of credit or the incurrence of such Indebtedness, such
         obligations are reimbursed within 30 days following such drawing or
         incurrence;

                  (viii) Indebtedness arising from agreements of the Company or
         a Restricted Subsidiary providing for indemnification, adjustment of
         purchase price or similar obligations, in each case, incurred or
         assumed in connection with the disposition of any business, assets or
         a Subsidiary, other than guarantees of Indebtedness incurred by any
         Person acquiring all or any portion of such business, assets or a
         Subsidiary for the purpose of financing such acquisition; provided,
         however, that (A) such Indebtedness is not reflected on the balance
         sheet of the Company or any Restricted Subsidiary (contingent
         obligations referred to in a footnote to financial statements and not
         otherwise reflected on the balance sheet shall not be deemed to be
         reflected on such balance sheet for purposes of this clause (A)) and
         (B) the maximum assumable liability in respect of all such
         Indebtedness shall at no time exceed the gross proceeds including
         noncash proceeds (the fair market value of such noncash proceeds being
         measured at the time received and without giving effect to any
         subsequent changes in value) actually received by the Company and its
         Restricted Subsidiaries in connection with such disposition;

                  (ix) the incurrence by the Company or any of its Restricted
         Subsidiaries of intercompany Indebtedness between or among the Company
         and any of its Restricted Subsidiaries; provided, however, that (A) if
         the Company is the obligor on such Indebtedness, such Indebtedness is
         expressly subordinated to the prior payment in full in cash of all
         Obligations with respect to the Notes and (B)(1) any subsequent
         issuance or transfer of Equity Interests that results in any such
         Indebtedness being held by a Person other than the Company or one of
         its Restricted Subsidiaries and (2) any sale or other transfer of any
         such Indebtedness to a Person that is not either the Company or one of
         its Restricted Subsidiaries shall be deemed, in each case, to
         constitute an incurrence of such Indebtedness by the Company or such
         Restricted Subsidiary, as the case may be;

                  (x) the incurrence by the Company or any of the Guarantors of
         Hedging Obligations that are incurred for the purpose of (A) fixing,
         hedging or capping interest rate risk with respect to any floating
         rate Indebtedness that is permitted by the terms of this Indenture to
         be outstanding or (B) protecting the Company and its Restricted
         Subsidiaries against changes in currency exchange rates;

                  (xi) the guarantee by the Company or any of the Guarantors of
         Indebtedness of the Company or a Restricted Subsidiary of the Company
         that was permitted to be incurred by another provision of this Section
         4.09;

                                      39
<PAGE>

                  (xii) the incurrence by the Company's Unrestricted
         Subsidiaries of Non-Recourse Debt, provided, however, that if any such
         Indebtedness ceases to be Non-Recourse Debt of an Unrestricted
         Subsidiary, such event shall be deemed to constitute an incurrence of
         Indebtedness by a Restricted Subsidiary of the Company that was not
         permitted by this clause (xii), and the issuance of preferred stock by
         Unrestricted Subsidiaries;

                  (xiii) obligations in respect of performance and surety bonds
         and completion guarantees provided by the Company or any Restricted
         Subsidiaries in the ordinary course of business; and

                  (xiv) the incurrence by the Company or any of its Restricted
         Subsidiaries of additional Indebtedness in an aggregate principal
         amount (or accreted value, as applicable) at any time outstanding,
         including all Permitted Refinancing Indebtedness then outstanding
         incurred to refund, refinance or replace any other Indebtedness
         incurred pursuant to this clause (xiv), not to exceed $50.0 million.

                  For purposes of determining compliance with this Section
4.09, in the event that an item of Indebtedness meets the criteria of more than
one of the categories of Permitted Debt described in clauses (i) through (xiv)
above or is entitled to be incurred pursuant to the first paragraph of this
Section 4.09, the Company shall, in its sole discretion, classify, or later
reclassify, such item of Indebtedness in any manner that complies with this
covenant. Accrual of interest, the accretion of accreted value and the payment
of interest in the form of additional Indebtedness shall not be deemed to be an
incurrence of Indebtedness for purposes of this Section 4.09.

SECTION 4.10. ASSET SALES.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company (or
the Restricted Subsidiary, as the case may be) receives consideration at the
time of such Asset Sale at least equal to the fair market value (evidenced by
an Officers' Certificate delivered to the Trustee which will include a
resolution of the Board of Directors with respect to such fair market value in
the event such Asset Sale involves aggregate consideration in excess of $5.0
million) of the assets or Equity Interests issued or sold or otherwise disposed
of and (ii) at least 80% of the consideration therefor received by the Company
or such Restricted Subsidiary, as the case may be, consists of cash, Cash
Equivalents and/or Marketable Securities; provided, however, that (A) the
amount of any Senior Debt of the Company or such Restricted Subsidiary that is
assumed by the transferee in any such transaction and (B) any consideration
received by the Company or such Restricted Subsidiary, as the case may be, that
consists of (1) all or substantially all of the assets of one or more Similar
Businesses, (2) other long-term assets that are used or useful in one or more
Similar Businesses and (3) Permitted Securities shall be deemed to be cash for
purposes of this provision.

                  Within 365 days after the receipt of any Net Proceeds from an
Asset Sale, the Company may apply such Net Proceeds, at its option, (i) to
repay Indebtedness under a Credit

                                      40
<PAGE>

Facility, or (ii) to the acquisition of Permitted Securities, all or
substantially all of the assets of one or more Similar Businesses, or the
making of a capital expenditure or the acquisition of other long-term assets in
a Similar Business. Pending the final application of any such Net Proceeds, the
Company may temporarily reduce Indebtedness under a Credit Facility or
otherwise invest such Net Proceeds in any manner that is not prohibited by this
Indenture. Any Net Proceeds from Asset Sales that are not applied or invested
as provided in the first sentence of this paragraph shall be deemed to
constitute "Excess Proceeds". When the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company shall make an offer to all holders of 1997
Notes (an "Asset Sale Offer") to purchase the maximum principal amount of 1997
Notes that may be purchased out of the Excess Proceeds, at an offer price in
cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest to the date of purchase, in accordance with the procedures
set forth in the 1997 Indenture. To the extent that the aggregate amount of
1997 Notes tendered pursuant to an Asset Sale Offer is less than the remaining
Excess Proceeds ("Remaining Excess Proceeds") and the sum of (A) such amount of
Remaining Excess Proceeds and (B) the Remaining Excess Proceeds from any
subsequent Asset Sale Offers exceeds $3.0 million, the Company will be required
to make an offer to all Holders of Notes and any other Indebtedness that ranks
pari passu with the Notes that, by its terms, requires the Company to offer to
repurchase such Indebtedness with such Remaining Excess Proceeds (a "Secondary
Asset Sale Offer") to purchase the maximum principal amount of Notes and pari
passu Indebtedness that may be purchased out of such Remaining Excess Proceeds,
at an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest thereon, if any, to the date of
purchase, in accordance with the procedures set forth in this Indenture. To the
extent that the aggregate amount of Notes or pari passu Indebtedness tendered
pursuant to a Secondary Asset Sale Offer is less than the Remaining Excess
Proceeds, the Company may use any Remaining Excess Proceeds for general
corporate purposes. If the aggregate principal amount of Notes or pari passu
Indebtedness surrendered by Holders thereof exceeds the amount of Remaining
Excess Proceeds in a Secondary Asset Sale Offer, the Company shall repurchase
such Indebtedness on a pro rata basis and the Trustee shall select the Notes to
be purchased on a pro rata basis. Upon completion of such offer to purchase,
the amount of Excess Proceeds shall be reset at zero.

SECTION 4.11. TRANSACTIONS WITH AFFILIATES.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless (i) such Affiliate Transaction is on terms that are no less favorable to
the Company or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (ii) the Company delivers to the
Trustee (A) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $5.0
million, a resolution of the Board of Directors set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with clause (i)
above and 


                                      41
<PAGE>


that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors and (B) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $15.0 million, an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing.

                  The foregoing provisions shall not prohibit: (i) any
employment agreement entered into by the Company or any of its Restricted
Subsidiaries in the ordinary course of business; (ii) any transaction with a
Lehman Investor; (iii) any transaction between or among the Company and/or its
Restricted Subsidiaries; (iv) transactions between the Company or any of its
Restricted Subsidiaries, on the one hand, and Lockheed Martin or any of its
Subsidiaries or a Permitted Joint Venture, on the other hand, on terms that are
not materially less favorable to the Company or the applicable Restricted
Subsidiary of the Company than those that could have been obtained from an
unaffiliated third party; provided that (A) in the case of any such transaction
or series of related transactions pursuant to this clause (iv) involving
aggregate consideration in excess of $5.0 million but less than $25.0 million,
such transaction or series of transactions (or the agreement pursuant to which
the transactions were executed) was approved by the Company's Chief Executive
Officer or Chief Financial Officer and (B) in the case of any such transaction
or series of related transactions pursuant to this clause (iv) involving
aggregate consideration equal to or in excess of $25.0 million, such
transaction or series of related transactions (or the agreement pursuant to
which the transactions were executed) was approved by a majority of the
disinterested members of the Board of Directors; (v) any transaction pursuant
to and in accordance with the provisions of the Transaction Documents as the
same are in effect on the Issue Date; and (vi) any Restricted Payment that is
permitted by the provisions of Section 4.07.

SECTION 4.12. LIENS.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien securing Indebtedness on any asset now owned or
hereafter acquired, or any income or profits therefrom or assign or convey any
right to receive income therefrom, except Permitted Liens.

SECTION 4.13. FUTURE SUBSIDIARY GUARANTEES.

                  If the Company or any of its Subsidiaries shall acquire or
create a Subsidiary (other than a Foreign Subsidiary or an Unrestricted
Subsidiary) after the Issue Date, then such Subsidiary shall execute a
Subsidiary Guarantee, in the form of the Supplemental Indenture attached hereto
as Exhibit B, and the Form of Notation on Senior Subordinated Note, attached
hereto as Exhibit C, and deliver an opinion of counsel as to the validity of
such Subsidiary Guarantee, in accordance with the terms of this Indenture. The
Subsidiary Guarantee of each Guarantor will be subordinated to the prior
payment in full of all Senior Debt of such Guarantor, which would include the
guarantees of amounts borrowed under the Senior Credit Facilities. The
obligations of each Guarantor under its Subsidiary Guarantee will be limited so
as not to constitute a fraudulent conveyance under applicable law.

                                      42
<PAGE>

                  No Guarantor may consolidate with or merge with or into
(whether or not such Guarantor is the surviving Person) another Person (except
the Company or another Guarantor) unless (i) subject to the provisions of the
following paragraph, the Person formed by or surviving any such consolidation
or merger (if other than such Guarantor) or to which such sale, assignment,
transfer, lease, conveyance or other disposition shall have been made assumes
all the obligations of such Guarantor pursuant to a supplemental indenture in
form and substance reasonably satisfactory to the Trustee, under the Notes and
this Indenture; (ii) immediately after giving effect to such transaction, no
Default or Event of Default exists; (iii) the Company (A) would be permitted by
virtue of the Company's pro forma Fixed Charge Coverage Ratio, immediately
after giving effect to such transaction, to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.09 or (B) would have a pro forma Fixed Charge Coverage Ratio that is
greater than the actual Fixed Charge Coverage Ratio for the same four-quarter
period without giving pro forma effect to such transaction.

                  Notwithstanding the foregoing paragraph, (i) any Guarantor
may consolidate with, merge into or transfer all or part of its properties and
assets to the Company and (ii) any Guarantor may merge with an Affiliate that
has no significant assets or liabilities and was incorporated solely for the
purpose of reincorporating such Guarantor in another State of the United States
so long as the amount of Indebtedness of the Company and its Restricted
Subsidiaries is not increased thereby.

                  In the event of a sale or other disposition of all of the
assets of any Guarantor, by way of merger, consolidation or otherwise, or a
sale or other disposition of all of the capital stock of any Guarantor, then
such Guarantor (in the event of a sale or other disposition, by way of such a
merger, consolidation or otherwise, of all of the capital stock of such
Guarantor) or the corporation acquiring the property (in the event of a sale or
other disposition of all of the assets of such Guarantor) will be released and
relieved of any obligations under its Subsidiary Guarantee; provided that the
Net Proceeds of such sale or other disposition are applied in accordance with
the applicable provisions of Section 4.10.

SECTION 4.14. CORPORATE EXISTENCE.

                  Subject to Article 5 hereof, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect (i)
its corporate existence, and the corporate, partnership or other existence of
each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any such Restricted Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and its Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Restricted Subsidiaries, if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and its Restricted Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

                                      43

SECTION 4.15. OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

                  (a) Upon the occurrence of a Change of Control, each Holder
of Notes shall have the right to require the Company to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101 % of the aggregate principal amount thereof
plus accrued and unpaid interest to the date of purchase (the "Change of
Control Payment"). Within ten days following any Change of Control, the Company
shall mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and offering to repurchase Notes on the
date specified in such notice, which date shall be no earlier than 30 days and
no later than 60 days from the date such notice is mailed (the "Change of
Control Payment Date"). Such notice, which shall govern the terms of the Change
of Control offer, shall state: (i) that the Change of Control Offer is being
made pursuant to this Section 4.15 and that all Notes tendered will be accepted
for payment; (ii) the purchase price and the purchase date; (iii) that any Note
not tendered will continue to accrue interest; (iv) that, unless the Company
defaults in the payment of the Change of Control Payment, all Notes accepted
for payment pursuant to the Change of Control Offer shall cease to accrue
interest after the Change of Control Payment Date; (v) that Holders electing to
have any Notes purchased pursuant to a Change of Control Offer will be required
to surrender the Notes, with the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Notes completed, to the Paying Agent at the
address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; (vi) that Holders
will be entitled to withdraw their election if the Paying Agent receives, not
later than the close of business on the second Business Day preceding the
Change of Control Payment Date, a telegram, telex, facsimile transmission or
letter setting forth the name of the Holder, the principal amount of Notes
delivered for purchase, and a statement that such Holder is withdrawing his
election to have the Notes purchased; and (vii) that Holders whose Notes are
being purchased only in part will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered, which unpurchased portion
must be equal to $1,000 in principal amount or an integral multiple thereof.
The Company shall comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of Notes
in connection with a Change of Control.

                  (b) On the Change of Control Payment Date, the Company shall,
to the extent lawful, (i) accept for payment all Notes or portions thereof
properly tendered pursuant to the Change of Control Offer, (ii) deposit with
the Paying Agent an amount equal to the Change of Control Payment in respect of
all Notes or portions thereof so tendered and (iii) deliver or cause to be
delivered to the Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company. The Paying Agent shall promptly mail to each
Holder of Notes so tendered the Change of Control Payment for such Notes, and
the Trustee shall promptly authenticate and mail (or cause to be transferred by
book entry) to each Holder a new Note equal in principal amount to any
unpurchased portion of the Notes surrendered, if any; provided that each such
new Note shall be


                                      44
<PAGE>

in a principal amount of $1,000 or an integral multiple thereof. Prior to
mailing a Change of Control Offer, but in any event within 90 days following a
Change of Control, the Company shall either repay all outstanding Senior Debt
or offer to repay all Senior Debt and terminate all commitments thereunder of
each lender who has accepted such offer or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Debt to permit the
repurchase of Notes required by this Section 4.15. The Company shall publicly
announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

SECTION 4.16. NO SENIOR SUBORDINATED DEBT.

                  The Company shall not incur, create, issue, assume, guarantee
or otherwise become liable for any Indebtedness that is subordinate or junior
in right of payment to any Senior Debt and senior in any respect in right of
payment to the Notes. No Guarantor shall incur, create, issue, assume,
guarantee or otherwise become liable for any Indebtedness that is subordinate
or junior in right of payment to any Senior Debt of a Guarantor and senior in
any respect in right of payment to any of the Subsidiary Guarantees.

SECTION 4.17. PAYMENTS FOR CONSENT.

                  Neither the Company nor any of its Subsidiaries shall,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any Holder of any Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Notes unless such consideration is offered
to be paid or is paid to all Holders of the Notes that consent, waive or agree
to amend in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.

SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

                  The Company may not consolidate or merge with or into
(whether or not the Company is the surviving corporation), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets in one or more related transactions, to another
corporation, Person or entity unless (i) the Company is the surviving
corporation or the entity or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United
States, any state thereof or the District of Columbia; (ii) the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company under the Notes and this Indenture pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee; (iii)
immediately after such transaction no Default or Event 


                                      45
<PAGE>


of Default exists; and (iv) except in the case of a merger of the Company with
or into a Wholly Owned Restricted Subsidiary of the Company, the Company or the
entity or Person formed by or surviving any such consolidation or merger (if
other than the Company), or to which such sale, assignment, transfer, lease,
conveyance or other disposition shall have been made, after giving pro forma
effect to such transaction as if such transaction had occurred at the beginning
of the most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding such transaction
either (A) would be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of Section 4.09 or (B) would have a pro forma Fixed Charge
Coverage Ratio that is greater than the actual Fixed Charge Coverage Ratio for
the same four-quarter period without giving pro forma effect to such
transaction.

                  Notwithstanding clause (iv) in the immediately foregoing
paragraph, (i) any Restricted Subsidiary may consolidate with, merge into or
transfer all or part of its properties and assets to the Company and (ii) the
Company may merge with an Affiliate that has no significant assets or
liabilities and was incorporated solely for the purpose of reincorporating the
Company in another State of the United States so long as the amount of
Indebtedness of the Company and its Restricted Subsidiaries is not increased
thereby.

SECTION 5.02. SUCCESSOR CORPORATION SUBSTITUTED.

                  Upon any consolidation or merger, or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of
the assets of the Company in accordance with Section 5.01 hereof, the successor
corporation formed by such consolidation or into or with which the Company is
merged or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), and may
exercise every right and power of the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the
obligation to pay the principal of and interest on the Notes except in the case
of a sale of all of the Company's assets that meets the requirements of Section
5.01 hereof.

                                   ARTICLE 6.
                             DEFAULTS AND REMEDIES

instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company
or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee
now exists, or is created after the date of this Indenture, which default
results in the acceleration of such Indebtedness prior to its express maturity
and, in each case, the principal amount of such Indebtedness, together with the
principal amount of any other such Indebtedness, together with the principal
amount of any other such Indebtedness, the maturity of which has been so
accelerated, aggregates $10.0 million or more;

                  (f) the Company or any of its Restricted Subsidiaries is

<PAGE>

                  (i) is for relief against the Company or any of its
         Significant Subsidiaries or any group of Subsidiaries that, taken as a
         whole, would constitute a Significant Subsidiary in an involuntary
         case;

         consecutive days; or

                  (iv) Except as permitted herein, any Subsidiary Guarantee
         shall be held in any judicial proceeding to be unenforceable or
         invalid.

                  The Holders of a majority in aggregate principal amount of
the Notes then outstanding by notice to the Trustee may on behalf of the
Holders of all of the Notes waive any existing Default or Event of Default and
its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Notes.

SECTION 6.02. ACCELERATION.

                  If any Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the then outstanding
Notes may declare all the Notes to be due and payable immediately; provided,
however, that so long as any Designated Senior Debt is outstanding, such
declaration shall not become effective until the earlier of (i) the day which
is five Business Days after receipt by the Representatives of Designated Senior
Debt of such notice of acceleration or (ii) the date of acceleration of any
Designated Senior Debt. Notwithstanding the foregoing, in the case of an Event
of Default arising from certain events of bankruptcy or insolvency, with
respect to the Company or any Restricted Subsidiary, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce this Indenture or the Notes except as provided in this
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Notes notice
of any continuing Default or Event of Default (except a Default or Event of
Default relating to the payment of principal or interest) if it determines that
withholding notice is in their interest.

                  In the case of any Event of Default occurring by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding payment of the premium that the Company
would have had to pay if the Company then had elected 


                                      48
<PAGE>


to redeem the Notes pursuant to the optional redemption provisions of this
Indenture, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law upon the acceleration of the Notes. If
an Event of Default occurs prior to May 15, 2003 by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding the prohibition on redemption of the Notes prior to
May 15, 2003, then the premium specified below shall also become immediately
due and payable to the extent permitted by law upon the acceleration of the
Notes during the twelve-month period ending on May 1 of the years indicated
below:

         YEAR                                           PERCENTAGE
         ----                                           ----------
         1998............................................112.752%
         1999............................................111.335%
         2000............................................109.918%
         2001............................................108.500%
         2002............................................107.084%
         2003............................................105.667%


SECTION 6.03. OTHER REMEDIES.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal, premium,
if any, and interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder of a Note 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. All
remedies are cumulative to the extent permitted by law.

SECTION 6.04. WAIVER OF PAST DEFAULTS.

                  Holders of not less than a majority in aggregate principal
amount of the then outstanding Notes by notice to the Trustee may on behalf of
the Holders of all of the Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default
in the payment of the principal of, premium, or interest on, the Notes
(including in connection with an offer to purchase) (provided, however, that
the Holders of a majority in aggregate principal amount at maturity of the then
outstanding Notes may rescind an acceleration and its consequences, including
any related payment default that resulted from such acceleration). Upon any
such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default
or impair any right consequent thereon.

                                      49
<PAGE>

SECTION 6.05. CONTROL BY MAJORITY.

                  Holders of a majority in principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability.

SECTION 6.06. LIMITATION ON SUITS.

                  A Holder of a Note may pursue a remedy with respect to this
Indenture or the Notes only if:

                  (a) the Holder of a Note gives to the Trustee written notice
of a continuing Event of Default;

                  (b) the Holders of at least 25% in principal amount of the
then outstanding Notes make a written request to the Trustee to pursue the
remedy;

                  (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

                  (d) the Trustee does not comply with the request within 60
days after receipt of the request and the offer and, if requested, the
provision of indemnity; and

                  (e) during such 60-day period the Holders of a majority in
principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

SECTION 6.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, premium and
interest on the Note, on or after the respective due dates expressed in the
Note (including in connection with an offer to purchase), or to bring suit for
the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default specified in Section 6.01(a) or (b)
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium and interest remaining unpaid


                                      50
<PAGE>

on the Notes and interest on overdue principal and, to the extent lawful,
interest 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 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

                  The Trustee is authorized to 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 the Notes allowed in any judicial proceedings relative to
the Company (or any other obligor upon the Notes), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder
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, 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 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

SECTION 6.10. PRIORITIES.

                  If the Trustee collects any money pursuant to this Article,
it shall pay out the money in the following order:

                  First: to the Trustee, its agents and attorneys for amounts
due under Section 7.07 hereof, including payment of all compensation, expense
and liabilities incurred, and all advances made, by the Trustee and the costs
and expenses of collection;

                  Second: to Holders of Notes for amounts due and unpaid on the
Notes for principal, premium and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for
principal, premium and interest, respectively; and

                  Third: to the Company or to such party as a court of
competent jurisdiction shall direct.

                                      51
<PAGE>

                  The Trustee may fix a record date and payment date for any
payment to Holders of Notes pursuant to this Section 6.10.

SECTION 6.11. 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 a 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 attorneys' 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 does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.

                                   ARTICLE 7.

SECTION 7.01. DUTIES OF TRUSTEE.

                  (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

                  (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture
         and no others, and no implied covenants or obligations shall be read
         into this Indenture against the Trustee; and

                  (ii) in the absence of bad faith or negligence on its part,
         the Trustee may conclusively rely, as to the truth of the statements
         and the correctness of the opinions expressed therein, upon
         certificates or opinions furnished to the Trustee and conforming to
         the requirements of this Indenture. However, the Trustee shall examine
         the certificates and opinions to determine whether or not they conform
         to the requirements of this Indenture (but need not confirm or
         investigate the accuracy of mathematical calculations or other facts
         stated therein).

                  (c) The Trustee may not be relieved from liabilities for its
own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

         of this Section;

<PAGE>

                  (ii) the Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer, unless it is
         proved that the Trustee was negligent in ascertaining the pertinent
         facts; and

                  (iii) 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 6.05 hereof.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject
to paragraphs (a), (b), and (c) of this Section.

                  (e) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or incur any liability. The Trustee shall be
under no obligation to exercise any of its rights and powers under this
Indenture at the request of any Holders, unless such Holder shall have offered
to the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

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

SECTION 7.02. RIGHTS OF TRUSTEE.

                  (a) The Trustee may conclusively rely 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 such
document.

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel or both. 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. The Trustee may
consult with counsel and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection from liability
in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon.

                  (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent
appointed with due care.

or omits to take in good faith that it believes to be authorized or within the
rights or powers conferred upon it by this Indenture.

<PAGE>

                  (e) Unless otherwise specifically provided in this Indenture,
any demand, request, direction or notice from the Company shall be sufficient
if signed by an Officer of the Company.

                  (f) 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 unless such Holders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or
direction.

                  (g) The Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by
it hereunder.

                  (h) The Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact
such a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Notes and this Indenture.

                  (i) Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company.

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may otherwise deal with the Company or
any Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with
like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11
hereof.

SECTION 7.04. TRUSTEE'S DISCLAIMERS.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes,
it shall not be accountable for the Company's use of the proceeds from the
Notes or any money paid to the Company or upon the Company's direction under
any provision of this Indenture, it shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee,
and it shall not be responsible for any statement or recital herein or any
statement in the Notes or any other document in connection with the sale of the
Notes or pursuant to this Indenture other than its certificate of
authentication.

                  If a Default or Event of Default occurs and is continuing and
if it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it occurs.
Except in the case of a Default or Event of Default in payment of principal of,
premium, if any, or interest on any Note, the Trustee may withhold the notice
if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of
the Notes.

SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

                  Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA ss. 313(a) (but if no
event described in TIA ss. 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA ss. 313(b)(2). The Trustee shall also transmit by mail
all reports as required by TIA ss. 313(c).

                  A copy of each report at the time of its mailing to the
Holders of Notes shall be mailed to the Company and filed with the SEC and each
stock exchange on which the Notes are listed in accordance with TIA ss. 313(d).
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

SECTION 7.07. COMPENSATION AND INDEMNITY.

                  The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred
or made by it in addition to the compensation for its services. Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

                  The Company shall indemnify the Trustee or any predecessor
Trustee against any and all losses, liabilities or expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this
Indenture against the Company (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company or any Holder or any
other person) or liability in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent any such loss,
liability or expense may be attributable to its negligence or bad faith. The
Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve
the Company of its obligations hereunder. The Company shall defend the claim
and the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such

                                      55
<PAGE>


counsel. The Company need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld.

                  The obligations of the Company under this Section 7.07 shall
survive the satisfaction and discharge of this Indenture.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(g) or (h) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses
of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.

                  The Trustee shall comply with the provisions of TIA ss.
313(b)(2) to the extent applicable.

SECTION 7.08. 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.

                  The Trustee may resign in writing at any time and be
discharged from the trust hereby created by so notifying the Company. The
Holders of Notes of a majority in principal amount of the then outstanding
Notes may remove the Trustee by so notifying the Trustee and the Company in
writing. The Company may remove the Trustee if:

                  (a) the Trustee fails to comply with Section 7.10 hereof;

                  (b) the Trustee is adjudged a bankrupt or an insolvent or an
order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

                  (c) a Custodian or public officer takes charge of the Trustee
or its property; or

                  (d) the Trustee 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. Within one year after the successor Trustee takes office,
the Holders of a majority in principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

                  If a successor Trustee does not take office within 30 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company, or the Holders of Notes of at least 10% in principal amount of the
then outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

                  If the Trustee, after written request by any Holder of a Note
who has been a Holder of a Note for at least six months, fails to comply with
Section 7.10, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

                                      56
<PAGE>

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, 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. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

                  If the Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Trustee.

SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

                  There shall at all times be a Trustee hereunder that is a
corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise
corporate trustee power, that is subject to supervision or examination by
federal or state authorities and that has a combined capital and surplus of at
least $50 million as set forth in its most recent published annual report of
condition.

                  This Indenture shall always have a Trustee who satisfies the
requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA
ss. 310(b).

SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                  The Trustee is subject to TIA ss. 311(a), excluding any
creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or
been removed shall be subject to TIA ss. 311(a) to the extent indicated
therein.

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

                  The Company may, at the option of its Board of Directors
evidenced by a resolution set forth in an Officers' Certificate, at any time,
elect to have either Section 8.02 or 8.03 hereof be

                                      57
<PAGE>

applied to all outstanding Notes upon compliance with the conditions set forth
below in this Article 8.

SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.02, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Notes
on the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall
be deemed to have paid and discharged the entire Indebtedness represented by
the outstanding Notes, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 8.05 hereof and the other Sections of this
Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of outstanding Notes to receive solely from the trust fund described in
Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (b) the Company's obligations with respect to such Notes
under Sections 2.06, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and the Company's
obligations in connection therewith and (d) this Article 8. Subject to
compliance with this Article 8, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof.

SECTION 8.03. COVENANT DEFEASANCE.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.03, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
4.13, 4.15 and 4.16 and Article 5 hereof with respect to the outstanding Notes
on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed
not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 6.01 hereof, but, except as
specified above, the remainder of this Indenture and such Notes shall be
unaffected thereby. In addition, upon the Company's exercise under Section 8.01
hereof of the option applicable to this Section 8.03 hereof, 

                                      58
<PAGE>


subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(d) through 6.01(f) hereof shall not constitute Events of Default.

SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

                  The following shall be the conditions to the application of
either Section 8.02 or 8.03 hereof to the outstanding Notes:

                  In order to exercise either Legal Defeasance or Covenant
Defeasance:

                  (a) the Company must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders, cash in United States dollars,
non-callable Government Securities, or a combination thereof, in such amounts
as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Notes on the stated date for payment thereof or on
the applicable redemption date, as the case may be;

                  (b) in the case of an election under Section 8.02 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Legal Defeasance had not occurred;

                  (c) in the case of an election under Section 8.03 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Covenant Defeasance had not occurred;

                  (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of
Default resulting from the incurrence of Indebtedness all or a portion of the
proceeds of which will be used to defease the Notes pursuant to this Article 8
concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

                  (e) such Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any
of its Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound;

                                      59
<PAGE>

                  (f) the Company shall have delivered to the Trustee an
opinion of counsel to the effect that on the 91st day following the deposit,
the trust funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally;

                  (g) the Company shall have delivered to the Trustee an
Officers' Certificate stating that the deposit was not made by the Company with
the intent of preferring the Holders over any other creditors of the Company or
with the intent of defeating, hindering, delaying or defrauding any other
creditors of the Company; and

                  (h) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE
              HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be segregated from other
funds except to the extent required by law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or
the principal and interest received in respect thereof other than any such tax,
fee or other charge which by law is for the account of the Holders of the
outstanding Notes.

                  Anything in this Article 8 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon the
request of the Company any money or non-callable Government Securities held by
it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

                                      60
<PAGE>

SECTION 8.06. REPAYMENT TO COMPANY.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of,
premium, if any, or interest on any Note and remaining unclaimed for two years
after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Company on its request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Note shall
thereafter, as a secured creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in The New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

SECTION 8.07. REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or non-callable Government Securities in accordance with Section
8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Indenture and The Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if
the Company makes any payment of principal of, premium, if any, or interest on
any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES.

                  Notwithstanding Section 9.02 of this Indenture, the Company
and the Trustee may amend or supplement this Indenture or the Notes without the
consent of any Holder of a Note:

                  (a) to cure any ambiguity, defect or inconsistency;

                  (b) to provide for uncertificated Notes in addition to or in
place of certificated Notes;

                  (c) to provide for the assumption of the Company's
obligations to the Holders of the Notes in the case of a merger or
consolidation pursuant to Article 5 hereof;

                                      61
<PAGE>

                  (a) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely
affect the legal rights hereunder of any Holder of the Note; or

                  (b) to comply with requirements of the SEC in order to effect
or maintain the qualification of this Indenture under the TIA.

                  Upon the request of the Company accompanied by a resolution
of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company in
the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES.

                  Except as provided below in this Section 9.02, the Company
and the Trustee may amend or supplement this Indenture (including Section 3.09,
4.10 and 4.15 hereof) and the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding (including consents obtained in connection with a tender offer
or exchange offer for the Notes), and, subject to Sections 6.04 and 6.07
hereof, any existing Default or Event of Default (other than a Default or Event
of Default in the payment of the principal of, premium, if any, or interest on
the Notes, except a payment default resulting from an acceleration that has
been rescinded) or compliance with any provision of this Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Notes (including consents obtained in connection with a
tender offer or exchange offer for the Notes).

                  Upon the request of the Company accompanied by a resolution
of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee shall join with the Company in the execution
of such amended or supplemental Indenture unless such amended or supplemental
Indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided, that unless such consent shall
have become effective by


                                      62
<PAGE>

virtue of the requisite percentage having been obtained prior to the date which
is 180 days after such record date, any such consent previously given shall
automatically and without further action by any Holder be canceled and of no
further effect.

                  It shall not be necessary for the consent of the Holders of
Notes under this Section 9.02 to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                  After an amendment, supplement or waiver under this Section
becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver may not (with respect to any Notes
held by a non-consenting Holder):

                  (a) reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver;

                  (b) reduce the principal of or change the fixed maturity of
any Note or alter or waive any of the provisions with respect to the redemption
of the Notes except as provided above with respect to Sections 4.10 and 4.15
hereof;

                  (c) reduce the rate of or change the time for payment of
interest, including default interest, on any Note;

                  (d) waive a Default or Event of Default in the payment of
principal of or premium, if any, or interest on the Notes (except a rescission
of acceleration of the Notes by the Holders of at least a majority in aggregate
principal amount of the then outstanding Notes and a waiver of the payment
default that resulted from such acceleration);

                  (e) make any Note payable in money other than that stated in
the Notes;

                  (f) make any change in the provisions of this Indenture
relating to waivers of past Defaults or the rights of Holders of Notes to
receive payments of principal of or interest on the Notes; or

                  (g) waive a redemption payment with respect to any Note
(other than a payment required by Sections 3.09, 4.10 and 4.15 hereof).

                  (h) make any change in Section 6.04 or 6.07 hereof or in the
foregoing amendment and waiver provisions.

                                      63
<PAGE>

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment or supplement to this Indenture or the Notes
shall be set forth in a amended or supplemental Indenture that complies with
the TIA as then in effect.

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent
Holder of a Note may revoke the consent as to its Note if the Trustee receives
written notice of revocation before the date the waiver, supplement or
amendment becomes effective. An amendment, supplement or waiver becomes
effective in accordance with its terms and thereafter binds every Holder.

SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES.

                  The Trustee may place an appropriate notation about an
amendment, supplement or waiver on any Note thereafter authenticated. The
Company in exchange for all Notes may issue and the Trustee shall authenticate
new Notes that reflect the amendment, supplement or waiver.

                  Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01) shall be
fully protected in relying upon, an Officer's Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                  ARTICLE 10.
                                 SUBORDINATION

SECTION 10.01. AGREEMENT TO SUBORDINATE.

                  The Company agrees, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Notes is subordinated in right
of payment, to the extent and in the manner provided in this Article 10, to the
prior payment in full in cash of all Senior Debt (whether outstanding on the
date hereof or hereafter created, incurred, assumed or guaranteed), and that
the subordination is for the benefit of the holders of Senior Debt.

                                      64

SECTION 10.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

                  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Company or its
property, an assignment for the benefit of creditors or any marshalling of the
Company's assets and liabilities, the holders of Senior Debt shall be entitled
to receive payment in full in cash of all Obligations due in respect of such
Senior Debt (including interest after the commencement of any such proceeding
at the rate specified in the applicable Senior Debt, whether or not an
allowable claim in any such proceeding) before the Holders of Notes will be
entitled to receive any payment with respect to the Notes, and until all
Obligations with respect to Senior Debt are paid in full in cash, any
distribution to which the Holders of Notes would be entitled shall be made to
the holders of Senior Debt (except, in each case, that Holders of Notes may
receive Permitted Junior Securities and payments made from the trust described
under Article 8).

SECTION 10.03. DEFAULT ON DESIGNATED SENIOR DEBT.

                  The Company may not make any payment or distribution to the
Trustee or any Holder in respect of Obligations with respect to the Notes and
may not acquire from the Trustee or any Holder any Notes for cash or property
(other than (i) securities that are subordinated to at least the same extent as
the Notes to (a) Senior Debt and (b) any securities issued in exchange for
Senior Debt and (ii) payments and other distributions made from any defeasance
trust created pursuant to Section 8.01 hereof) until all principal and other
Obligations with respect to the Senior Debt have been paid in full if:

                  (i) a default in the payment of any principal or other
         Obligations with respect to Designated Senior Debt occurs and is
         continuing; or

                  (ii) a default, other than a payment default, on Designated
         Senior Debt occurs and is continuing that then permits holders of the
         Designated Senior Debt to accelerate its maturity and the Trustee
         receives a notice of the default (a "Payment Blockage Notice") from
         the Company or a Representative with respect to such Designated Senior
         Debt. If the Trustee receives any such Payment Blockage Notice, no
         subsequent Payment Blockage Notice shall be effective for purposes of
         this Section unless and until (i) at least 360 days shall have elapsed
         since the effectiveness of the immediately prior Payment Blockage
         Notice and (ii) all scheduled payments of principal, premium, if any,
         and interest on the Notes that have come due have been paid in full in
         cash. No nonpayment default that existed or was continuing on the date
         of delivery of any Payment Blockage Notice to the Trustee shall be, or
         be made, the basis for a subsequent Payment Blockage Notice unless
         such default shall have been waived or cured for a period of not less
         than 90 days.

                  The Company may and shall resume payments on and
distributions in respect of the Notes and may acquire them upon the earlier of:

                                      65
<PAGE>

                                    (1) the date upon which the default is
                  cured or waived, or

                                    (2) in the case of a default referred to in
                  Section 10.03(ii) hereof, 179 days pass after notice is
                  received if the maturity of such Designated Senior Debt has
                  not been accelerated,

if this Article otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

SECTION 10.04. ACCELERATION OF SECURITIES.

                  If payment of the Securities is accelerated because of an
Event of Default, the Company shall promptly notify holders of Senior Debt of
the acceleration.

SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER.

                  In the event that the Trustee or any Holder receives any
payment of any Obligations with respect to the Notes at a time when the Trustee
or such Holder, as applicable, has actual knowledge that such payment is
prohibited by Article 10 hereof, such payment shall be held by the Trustee or
such Holder, in trust for the benefit of, and shall be paid forthwith over and
delivered, upon written request, to, the holders of Senior Debt as their
interests may appear or their Representative under the indenture or other
agreement (if any) pursuant to which Senior Debt may have been issued, as their
respective interests may appear, for application to the payment of all
Obligations with respect to Senior Debt remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders
of Senior Debt.

                  With respect to the holders of Senior Debt, the Trustee
undertakes to perform only such obligations on the part of the Trustee as are
specifically set forth in this Article 10, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt, and shall not be liable to any
such holders if the Trustee shall pay over or distribute to or on behalf of
Holders or the Company or any other Person money or assets to which any holders
of Senior Debt shall be entitled by virtue of this Article 10, except if such
payment is made as a result of the willful misconduct or negligence of the
Trustee.

SECTION 10.06. NOTICE BY COMPANY

                  The Company shall promptly notify the Trustee and the Paying
Agent of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes to violate this Article 10, but failure
to give such notice shall not affect the subordination of the Notes to the
Senior Debt as provided in this Article 10.

                  The Trustee shall be entitled to rely on the delivery to it
of a written notice by a person representing himself to be a holder of Senior
Debt (or a trustee or agent on behalf of such

                                      66
<PAGE>

holder) to establish that such notice has been given by a holder of Senior Debt
(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 holder of Senior Debt to participate in any
payment or distribution pursuant to this Article 10, the Trustee may request
such person to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Debt held by such person, the extent to which such
person is entitled to participate in such evidence is not furnish, the Trustee
may defer any payment which it may be required to make for the benefit of such
person pursuant to the terms of this Indenture pending judicial determination
as to the rights of such person to receive such payment.

SECTION 10.07. SUBROGATION.

                  After all Senior Debt is paid in full in cash and until the
Notes are paid in full, Holders of Notes shall be subrogated (equally and
ratably with all other Indebtedness pari passu with the Notes) to the rights of
holders of Senior Debt to receive distributions applicable to Senior Debt to
the extent that distributions otherwise payable to the Holders of Notes have
been applied to the payment of Senior Debt. A distribution made under this
Article 10 to holders of Senior Debt that otherwise would have been made to
Holders of Notes is not, as between the Company and Holders, a payment by the
Company on the Notes.

SECTION 10.08. RELATIVE RIGHTS.

                  This Article 10 defines the relative rights of Holders of
Notes and holders of Senior Debt. Nothing in this Indenture shall:

                                    (1) impair, as between the Company and
                  Holders of Notes, the obligation of the Company, which is
                  absolute and unconditional, to pay principal of and interest
                  on the Notes in accordance with their terms;

                                    (2) affect the relative rights of Holders
                  of Notes and creditors of the Company other than their rights
                  in relation to holders of Senior Debt; or

                                    (3) prevent the Trustee or any Holder of
                  Notes from exercising its available remedies upon a Default
                  or Event of Default, subject to the rights of holders and
                  owners of Senior Debt to receive distributions and payments
                  otherwise payable to Holders of Notes.

                  If the Company fails because of this Article 10 to pay
principal of or interest on a Note on the due date, the failure is still a
Default or Event of Default.

SECTION 10.09. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

                  No right of any holder of Senior Debt to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any Holder to comply with this Indenture.

                                      67
<PAGE>

SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

                  Whenever a distribution is to be made or a notice given to
holders of Senior Debt, the distribution may be made and the notice given to
their Representative.

                  Upon any payment or distribution of assets of the Company
referred to in this Article 10, the Trustee and the Holders of Notes shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Notes for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior Debt
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 10.

SECTION 10.11. RIGHTS OF TRUSTEE AND PAYING AGENT.

                  Notwithstanding the provisions of this Article 10 or any
other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment or distribution by the Trustee, and the Trustee and the Paying Agent
may continue to make payments on the Notes, unless the Trustee shall have
received at its Corporate Trust Office at least three Business Days prior to
the date of such payment written notice of facts that would cause the payment
of any Obligations with respect to the Notes to violate this Article 10. Only
the Company or a Representative may give the notice. Nothing in this Article 10
shall impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

                  The Trustee in its individual or any other capacity may hold
Senior Debt with the same rights it would have if it were not Trustee. Any
Agent may do the same with like rights.

SECTION 10.12. AUTHORIZATION TO EFFECT SUBORDINATION.

                  Each Holder of Notes, by the Holder's acceptance thereof,
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination as provided
in this Article 10, and appoints the Trustee to act as such Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding
referred to in Section 6.09 hereof at least 30 days before the expiration of
the time to file such claim, the credit agents are hereby authorized to file an
appropriate claim for and on behalf of the Holders of the Notes.

SECTION 10.13. AMENDMENTS.

                  The provisions of this Article 10 shall not be amended or
modified without the written consent of the holders of at least 75% in
aggregate principal amount of the Notes then outstanding if such amendment
would adversely affect the rights of Holders of Notes.

SECTION 11.01. TRUST INDENTURE ACT CONTROLS.

                  If any provision of this Indenture limits, qualifies or
conflicts with the duties imposed by TIA ss.318(c), the imposed duties shall

the others is duly given if in writing and delivered in Person or mailed by

above within the time prescribed, it is duly given, whether or not the
addressee receives it.

                  If the Company mails a notice or communication to Holders, it

SECTION 11.03. COMMUNICATIONS BY HOLDERS OF NOTES WITH OTHER HOLDERS OF NOTES.

                  Holders may communicate pursuant to TIA ss. 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The
Company, the Trustee, the Registrar and anyone else shall have the protection
of TIA ss. 312(c).

SECTION 11.04. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

                  Upon any request or application by the Company to the Trustee
to take any action under this Indenture, the Company shall furnish to the
Trustee:

                  (a) an Officers' Certificate in form and substance reasonably
satisfactory to the Trustee (which shall include the statements set forth in
Section 11.05 hereof) stating that, in the opinion of the signers, all
conditions precedent and covenants, if any, provided for in this Indenture
relating to the proposed action have been satisfied; and

                  (b) an Opinion of Counsel in form and substance reasonably
satisfactory to the Trustee (which shall include the statements set forth in
Section 11.05 hereof) stating that, in the opinion of such counsel, all such
conditions precedent and covenants have been satisfied.

SECTION 11.05. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

                  Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than a certificate
provided pursuant to TIA ss. 314(a)(4)) shall comply with the provisions of TIA
ss. 314(e) and shall include:

                  (a) a statement that the Person making such certificate or

of the Company, as such, shall have any liability for any obligations of the
Company under the Notes and this Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder of
Notes by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Notes. Such
waiver may not be effective to waive liabilities under the federal securities
laws and it is the view of the Commission that such a waiver is against public
policy. SECTION 11.08. GOVERNING LAW.

                  THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE
USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES,

other Person. Any such indenture, loan or debt agreement may not be used to
interpret this Indenture.

SECTION 11.10. SUCCESSORS.

                  All agreements of the Company in this Indenture and the Notes
shall bind its successors. All agreements of the Trustee in this Indenture
shall bind its successors.

SECTION 11.11. SEVERABILITY.

                  In case any provision in this Indenture or in the Notes shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

SECTION 11.12. COUNTERPART ORIGINALS.

Each signed copy shall be an original, but all of them together represent the
same agreement.

SECTION 11.13. TABLE OF CONTENTS, HEADINGS, ETC.

                   8 1/2% Senior Subordinated Notes due 2008

[THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE
BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY
CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated

         1. INTEREST. L-3 Communications Corporation, a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Note
at 8 1/2% per annum from May 22, 1998 until maturity. The Company shall pay
interest semi-annually in arrears on May 15 and November 15, commencing on
November 15, 1998, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"), with the same force
and effect as if made on the date for such payment. Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
November 15. The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium,
if any, from time to time on demand at a rate that is 1% per annum in excess of
the rate then in effect; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace
periods) from time to time on demand at the same rate to the extent lawful.
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 Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the May 1 or November 1 next (whether or not a
Business Day) preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest

Payment Date, except as provided in Section 2.12 of the Indenture with respect
to defaulted interest. The Notes will be payable as to principal, premium, if
any, and interest at the office or agency of the Company maintained for such
purpose within The City and State of New York, or, at the option of the
Company, payment of interest may be made by check mailed to the Holders at
their addresses set forth in the register of Holders; provided that payment by
wire transfer of immediately available funds will be required with respect to
principal of and interest, premium on, all Global Notes and all other Notes the
Holders of which shall have provided wire transfer instructions to the Company
or the Paying Agent if such Holders shall be registered Holders of at least
$250,000 in principal amount of the Notes. Such payment shall be in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of May 22, 1998 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code ss.ss. 77aaa-77bbbb). The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms. To
the extent any provision of this Note conflicts with the express provisions of
the Indenture, the provisions of the Indenture shall govern and be controlling.
The Notes issuable under the Indenture are obligations of the Company limited
to $250.0 million in aggregate principal amount.

         5. OPTIONAL REDEMPTION.

                  (a) Except as set forth in clause (b) of this paragraph 5,
the Notes shall not be redeemable at the Company's option prior to May 15,
2003. Thereafter, the Notes shall be subject to redemption at any time at the
option of the Company, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest thereon, to
the applicable redemption date, if redeemed during the twelve-month period
beginning on May 15 of the years indicated below:

           YEAR                                           PERCENTAGE
           ----                                           ----------
           2003.........................................    104.250%
           2004.........................................    102.833%
           2005.........................................    101.417%
           2006 and thereafter..........................    100.000%


                                      A-3
<PAGE>

                  (b) Notwithstanding the foregoing, during the first 36 months
after the date of the Indenture, the Company may on any one or more occasions
redeem up to an aggregate of 35% of the Notes originally issued at a redemption
price of 108.500% of the principal amount thereof, plus accrued and unpaid
interest to the redemption date, with the net cash proceeds of one or more
Equity Offerings by the Company or the net cash proceeds of one or more Equity
Offerings by Holdings that are contributed to the Company as common equity
capital; provided that at least 65% of the Notes originally issued remain
outstanding immediately after the occurrence of each such redemption; and
provided, further, that any such redemption must occur within 120 days of the
date of the closing of such Equity Offering.

         6. MANDATORY REDEMPTION.

                  Except as set forth in paragraph 7 below, the Company shall
not be required to make mandatory redemption payments with respect to the
Notes.

         7. REPURCHASE AT OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company shall be
required to make an offer (a "Change of Control Offer") to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of each Holder's
Notes at a purchase price equal to 101% of aggregate principal amount thereof
plus accrued and unpaid interest, if any, to the date of purchase (in either
case, the "Change of Control Payment"). Within 10 days following any Change of
Control, the Company shall mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture.

                  (b) If the Company or a Subsidiary consummates any Asset
Sales, within five Business Days of each date on which the aggregate amount of
Excess Proceeds exceeds $10.0 million, the Company shall commence an offer to
all holders of 1997 Notes (as "Asset Sale Offer") pursuant to Section 3.09 of
the Indenture to purchase the maximum principal amount of 1997 Notes that may
be purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
to the date of purchase, in accordance with the procedures set forth in the
1997 Indenture. To the extent that the aggregate amount of 1997 Notes tendered
pursuant to an Asset Sale Offer is less than the remaining Excess Proceeds
("Remaining Excess Proceeds") and the sum of (A) such amount of Remaining
Excess Proceeds and (B) the Remaining Excess Proceeds from any subsequent Asset
Sale Offers exceeds $3.0 million, the Company will be required to make an offer
to all Holders of Notes and any other Indebtedness that ranks pari passu with
the Notes that, by its terms, requires the Company to offer to repurchase such
Indebtedness with such Remaining Excess Proceeds (a "Secondary Asset Sale
Offer") to purchase the maximum principal amount of Notes and pari passu
Indebtedness that may be purchased out of such Remaining Excess Proceeds, at an
offer price in cash in an amount equal to 100% of the principal amount thereof
plus accrued and unpaid interest thereon, if any, to the date of purchase, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Notes or pari passu Indebtedness tendered pursuant to a
Secondary Asset Sale Offer is less than the Remaining Excess Proceeds, the
Company may use any Remaining Excess 


                                      A-4
<PAGE>

Proceeds for general corporate purposes. If the aggregate principal amount of
Notes or pari passu Indebtedness surrendered by Holders thereof exceeds the
amount of Remaining Excess Proceeds in a Secondary Asset Sale Offer, the
Company shall repurchase such Indebtedness on a pro rata basis and the Trustee
shall select the Notes to be purchased on a pro rata basis. Holders of Notes
that are the subject of an offer to purchase will receive an Asset Sale Offer
from the Company prior to any related purchase date and may elect to have such
Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Notes.

         8. 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
whose Notes are to be redeemed at its registered address. Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided
in the Indenture. The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and
the Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date
and the corresponding Interest Payment Date.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act.

                                      A-5

         12. DEFAULTS AND REMEDIES. An "Event of Default" occurs if: (i)
default for 30 days in the payment when due of interest on the Notes (whether
or not prohibited by the subordination provisions of the Indenture); (ii)
default in payment when due of the principal of or premium, if any, on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (iii) failure by the Company to comply with the covenants contained
in sections 4.10, 4.15 or 5.10 of the Indenture; (iv) failure by the Company
for 60 days after notice to comply with any of its other agreements in the
Indenture or the Notes; (v) default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists,
or is created after the Issue Date, which default results in the acceleration
of such Indebtedness prior to its express maturity and, in each case, the
principal amount of any such Indebtedness, together with the principal amount
of any other such Indebtedness the maturity of which has been so accelerated,
aggregates $10.0 million or more; (vi) failure by the Company or any of its
Restricted Subsidiaries to pay final judgments aggregating in excess of $10.0
million, which judgments are not paid, discharged or stayed for a period of 60
days; (vii) certain events of bankruptcy or insolvency with respect to the
Company or any of its Significant Subsidiaries; and (viii) except as permitted
by the Indenture, any Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid.

         If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately; provided, however,
that so long as any Designated Senior Debt is outstanding, such declaration
shall not become effective until the earlier of (i) the day which is five
Business Days after receipt by the Representatives of Designated Senior Debt of
such notice of acceleration or (ii) the date of acceleration of any Designated
Senior Debt. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, with respect to the
Company or any Restricted Subsidiary, all outstanding Notes will become due and
payable without further action or notice. Holders of the Notes may not enforce
the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have
had to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to May
15, 2003 by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to May 15, 2003, then the


                                      A-6
<PAGE>

premium specified in the Indenture shall also become immediately due and
payable to the extent permitted by law upon the acceleration of the Notes.

         The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all
of the Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Notes.

         13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, 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 the Trustee.

         14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

         15. AUTHENTICATION. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

         17. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         18. GOVERNING LAW. The internal law of the State of New York shall
govern and be used to construe this Note, without regard to the principles of
conflicts of laws.

         The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture. Requests may be made to:

                           Subsidiary Guarantee substantially in the form of
                           Exhibit C to the Indenture shall be endorsed by an
                           officer of such Guaranteeing Subsidiary on each
                           Senior Note authenticated and delivered by the
                           Trustee after the date hereof.

                  (b)      Notwithstanding the foregoing, the Guaranteeing
                           Subsidiary hereby agrees that its Subsidiary
                           Guarantee set forth herein shall remain in full
                           force and effect notwithstanding any failure to

                           Supplemental Indenture or on the Subsidiary
                           Guarantee no longer holds that office at the time
                           the Trustee authenticates the Senior Note on which a
                           Subsidiary Guarantee is endorsed, the Subsidiary
                           Guarantee shall be valid nevertheless.

                  (d)      The delivery of any Senior Note by the Trustee,

                           obligations hereunder shall be unconditional,
                           regardless of the validity, regularity or
                           enforceability of the Notes or the Indenture, the

                           circumstance which might otherwise constitute a
                           legal or equitable discharge or defense of a
                           guarantor.

                           presentment, demand of payment, filing of claims
                           with a court in the event of insolvency or

                           Supplemental Indenture will not be discharged except
                           by complete performance of the obligations contained
                           in the Notes and the Indenture.

                  (g)      If any Holder or the Trustee is required by any
                           court or otherwise to return to the Company or the
                           Guaranteeing Subsidiary, or any Custodian, Trustee,

                           Subsidiary, any amount paid by either to the Trustee
                           or such Holder, the Subsidiary Guarantee made
                           pursuant to this Supplemental Indenture, to the
                           extent theretofore discharged, shall be reinstated
                           in full force and effect.

                  (h)      The Guaranteeing Subsidiary agrees that it shall not
                           be entitled to any right of subrogation in relation
                           to the Holders in respect of any obligations
                           guaranteed hereby until payment in full of all
                           obligations guaranteed hereby. The Guaranteeing
                           Subsidiary further agrees that, as between the

                                    hereby may be accelerated as provided in
                                    Article 6 of the Indenture for the purposes
                                    of the Subsidiary Guarantee made pursuant
                                    to this Supplemental Indenture,
                                    notwithstanding any stay, injunction or
                                    other prohibition preventing such
                                    acceleration in respect of the obligations
                                    guaranteed hereby; and

                           (ii)     in the event of any declaration of
                                    acceleration of such obligations as
                                    provided in Article 6 of the Indenture,
                                    such obligations (whether or not due and
                                    payable) shall forthwith become due and
                                    payable by the Guaranteeing Subsidiary for

                                    Indenture.

                           seek contribution from any other non-paying
                           Guaranteeing Subsidiary so long as the exercise of
                           such right does not impair the rights of the Holders
                           or the Trustee under the Subsidiary Guarantee made

                           successors shall be a party or parties, or shall

                           assumed (in the event that the Guaranteeing
                           Subsidiary is not the surviving corporation in the
                           merger), by supplemental indenture satisfactory in
                           form to the Trustee, executed and delivered to the
                           Trustee, by the corporation formed by such
                           consolidation, or into which the Guaranteeing
                           Subsidiary shall have been merged, or by the
                           corporation which shall have acquired such property

                           or Event of Default exists.

                  (c)      In case of any such consolidation, merger, sale or
                           conveyance and upon the assumption by the successor

                           Guaranteeing Subsidiary with the same effect as if
                           it had been named herein as the Guaranteeing
                           Subsidiary. Such successor corporation thereupon may
                           cause to be signed any or all of the Subsidiary
                           Guarantees to be endorsed upon the Notes issuable
                           under the Indenture which theretofore shall not have

                           Trustee. All the Subsidiary Guarantees so issued
                           shall in all respects have the same legal rank and
                           benefit under the Indenture and this Supplemental
                           Indenture as the Subsidiary Guarantees theretofore
                           and thereafter issued in accordance with the terms
                           of the Indenture and this Supplemental Indenture as
                           though all of such Subsidiary Guarantees had been
                           issued at the date of the execution hereof.

                           obligations of such Guaranteeing Subsidiary under
                           the Indenture as provided in this Supplemental
                           Indenture.

                  (b)      Upon the designation of a Guaranteeing Subsidiary as
                           an Unrestricted Subsidiary in accordance with the
                           terms of the Supplemental Indenture, such
                           Guaranteeing Subsidiary shall be released and
                           relieved of its obligations under its Subsidiary
                           Guarantee and this Supplemental Indenture. Upon
                           delivery by the Company to the Trustee of an
                           Officers' Certificate and an Opinion of Counsel to
                           the effect that such designation of such
                           Guaranteeing Subsidiary as an Unrestricted
                           Subsidiary was made by the Company in accordance
                           with the provisions of this Supplemental Indenture,
                           also including without limitation Section 4.07 of
                           the Indenture, the Trustee shall execute any
                           documents reasonably required in order to evidence
                           the release of such Guaranteeing Subsidiary from its
                           obligations under its Subsidiary Guarantee. Any
                           Guaranteeing Subsidiary not released from its
                           obligations under its Subsidiary Guarantee shall
                           remain liable for the full amount of principal of
                           and interest on the Notes and for the other
                           obligations of any Guaranteeing Subsidiary under the
                           Indenture as provided in Article 10.

         6. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the
Company or any Guaranteeing Subsidiary under the Notes, any Subsidiary
Guarantees, the Indenture or this Supplemental Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Notes by accepting a Senior Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Notes. Such waiver may not be effective to waive liabilities under the
federal securities laws and it is the view of the Commission that such a waiver
is against public policy.

         7. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

         8. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         9. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         10. THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiary and the
Company.

                                   EXHIBIT C

 FORM OF NOTATION ON SENIOR SUBORDINATED NOTE RELATING TO SUBSIDIARY GUARANTEE

                  Pursuant to the Supplemental Indenture (the "Supplemental

Subsidiary Guarantee shall be reduced to the maximum amount permissible under
such fraudulent conveyance or similar law.

                  No past, present or future director, officer, employee,
agent, incorporator, stockholder or agent of any Guaranteeing Subsidiary, as
such, shall have any liability for any obligations of the Company or any
Guaranteeing Subsidiary under the Notes, any Subsidiary Guarantee, Indenture,
any supplemental indenture delivered pursuant to the Indenture by such
Guaranteeing Subsidiary or any Subsidiary Guarantees, or for any claim based
on, in respect of or by reason of such obligations or their creation. Each

for any purpose until the certificate of authentication on the Note upon which

<PAGE>



         1. INTEREST. L-3 Communications Corporation, a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Note
at 8 1/2% per annum from May 22, 1998 until maturity. The Company shall pay
interest semi-annually in arrears on May 15 and November 15, commencing on
November 15, 1998, or if any such day is not a Business Day, on the next
succeeding Business Day (each an "Interest Payment Date"), with the same force
and effect as if made on the date for such payment. Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
November 15. The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium,
if any, from time to time on demand at a rate that is 1% per annum in excess of
the rate then in effect; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace
periods) from time to time on demand at the same rate to the extent lawful.
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 Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the May 1 or November 1 next (whether or not a
Business Day) preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Notes will be payable as to principal, premium, if any, and
interest at the office or agency of the Company maintained for such purpose
within The City and State of New York, or, at the option of the Company,
payment of interest may be made by check mailed to the Holders at their
addresses set forth in the register of Holders; provided that payment by wire
transfer of immediately available funds will be required with respect to
principal of and interest, premium on, all Global Notes and all other Notes the
Holders of which shall have provided wire transfer instructions to the Company
or the Paying Agent if such Holders shall be registered Holders of at least
$250,000 in principal amount of the Notes. Such payment shall be in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of May 22, 1998 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code ss.ss. 77aaa-77bbbb). The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such 

                                       2
<PAGE>

terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and
be controlling. The Notes issuable under the Indenture are obligations of the
Company limited to $250.0 million in aggregate principal amount.

         5.       OPTIONAL REDEMPTION.

                  (a) Except as set forth in clause (b) of this paragraph 5,
the Notes shall not be redeemable at the Company's option prior to May 15,
2003. Thereafter, the Notes shall be subject to redemption at any time at the
option of the Company, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest thereon, to
the applicable redemption date, if redeemed during the twelve-month period
beginning on May 15 of the years indicated below:

     YEAR                                               PERCENTAGE
     2003............................................     104.250%
     2004............................................     102.833%
     2005............................................     101.417%
     2006 and thereafter.............................     100.000%


                  (b) Notwithstanding the foregoing, during the first 36 months
after the date of the Indenture, the Company may on any one or more occasions
redeem up to an aggregate of 35% of the Notes originally issued at a redemption
price of 108.500% of the principal amount thereof, plus accrued and unpaid
interest to the redemption date, with the net cash proceeds of one or more
Equity Offerings by the Company or the net cash proceeds of one or more Equity
Offerings by Holdings that are contributed to the Company as common equity
capital; provided that at least 65% of the Notes originally issued remain
outstanding immediately after the occurrence of each such redemption; and
provided, further, that any such redemption must occur within 120 days of the
date of the closing of such Equity Offering.

         6.       MANDATORY REDEMPTION.

                  Except as set forth in paragraph 7 below, the Company shall
not be required to make mandatory redemption payments with respect to the
Notes.

         7.       REPURCHASE AT OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company shall be
required to make an offer (a "Change of Control Offer") to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of each Holder's
Notes at a purchase price equal to 101% of aggregate principal amount thereof
plus accrued and unpaid interest, if any, to the date of purchase (in either
case, the "Change of Control Payment"). Within 10 days following any Change of
Control, the 


                                       3
<PAGE>

Company shall mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture.

                  (b) If the Company or a Subsidiary consummates any Asset
Sales, within five Business Days of each date on which the aggregate amount of
Excess Proceeds exceeds $10.0 million, the Company shall commence an offer to
all holders of 1997 Notes (as "Asset Sale Offer") pursuant to Section 3.09 of
the Indenture to purchase the maximum principal amount of 1997 Notes that may
be purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
to the date of purchase, in accordance with the procedures set forth in the
1997 Indenture. To the extent that the aggregate amount of 1997 Notes tendered
pursuant to an Asset Sale Offer is less than the remaining Excess Proceeds
("Remaining Excess Proceeds") and the sum of (A) such amount of Remaining
Excess Proceeds and (B) the Remaining Excess Proceeds from any subsequent Asset
Sale Offers exceeds $3.0 million, the Company will be required to make an offer
to all Holders of Notes and any other Indebtedness that ranks pari passu with
the Notes that, by its terms, requires the Company to offer to repurchase such
Indebtedness with such Remaining Excess Proceeds (a "Secondary Asset Sale
Offer") to purchase the maximum principal amount of Notes and pari passu
Indebtedness that may be purchased out of such Remaining Excess Proceeds, at an
offer price in cash in an amount equal to 100% of the principal amount thereof
plus accrued and unpaid interest thereon, if any, to the date of purchase, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Notes or pari passu Indebtedness tendered pursuant to a
Secondary Asset Sale Offer is less than the Remaining Excess Proceeds, the
Company may use any Remaining Excess Proceeds for general corporate purposes.
If the aggregate principal amount of Notes or pari passu Indebtedness
surrendered by Holders thereof exceeds the amount of Remaining Excess Proceeds
in a Secondary Asset Sale Offer, the Company shall repurchase such Indebtedness
on a pro rata basis and the Trustee shall select the Notes to be purchased on a
pro rata basis. Holders of Notes that are the subject of an offer to purchase
will receive an Asset Sale Offer from the Company prior to any related purchase
date and may elect to have such Notes purchased by completing the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Notes.

         8. 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
whose Notes are to be redeemed at its registered address. Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided
in the Indenture. The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and
the Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any 


                                       4
<PAGE>

Note being redeemed in part. Also, it need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be
redeemed or during the period between a record date and the corresponding
Interest Payment Date.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act.

         12. DEFAULTS AND REMEDIES. An "Event of Default" occurs if: (i)
default for 30 days in the payment when due of interest on the Notes (whether
or not prohibited by the subordination provisions of the Indenture); (ii)
default in payment when due of the principal of or premium, if any, on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (iii) failure by the Company to comply with the covenants contained
in sections 4.10, 4.15 or 5.10 of the Indenture; (iv) failure by the Company
for 60 days after notice to comply with any of its other agreements in the
Indenture or the Notes; (v) default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists,
or is created after the Issue Date, which default results in the acceleration
of such Indebtedness prior to its express maturity and, in each case, the
principal amount of any such Indebtedness, together with the principal amount
of any other such Indebtedness the maturity of which has been so accelerated,
aggregates $10.0 million or more; (vi) failure by the Company or any of its
Restricted Subsidiaries to pay final judgments aggregating in excess of $10.0
million, which judgments are not paid, discharged or stayed for a period of 60
days; (vii) certain events of bankruptcy or insolvency with respect to the
Company or any of its Significant Subsidiaries; and (viii) except as permitted
by the Indenture, any Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid.

         If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately; provided, however,
that so long as any Designated Senior Debt is outstanding, such declaration
shall not become effective until the earlier of (i) the day which is 


                                       5
<PAGE>

five Business Days after receipt by the Representatives of Designated Senior
Debt of such notice of acceleration or (ii) the date of acceleration of any
Designated Senior Debt. Notwithstanding the foregoing, in the case of an Event
of Default arising from certain events of bankruptcy or insolvency, with
respect to the Company or any Restricted Subsidiary, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of
the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have
had to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to May
15, 2003 by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to May 15, 2003, then the premium specified in
the Indenture shall also become immediately due and payable to the extent
permitted by law upon the acceleration of the Notes.

         The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all
of the Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Notes.

         13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, 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 the Trustee.

         14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

         15. AUTHENTICATION. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

         17. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         18. GOVERNING LAW. The internal law of the State of New York shall
govern and be used to construe this Note, without regard to the principles of
conflicts of laws.

         The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture. Requests may be made to:

                              SUBSIDIARY GUARANTEE

                  Pursuant to the Supplemental Indenture (the "Supplemental
Indenture") dated as of May 22, 1998 among The Bank of New York, as trustee
(the "Trustee"), and Hygienetics Environmental Services, Inc., a Delaware
corporation, L-3 Communications ILEX Systems, Inc., a Delaware corporation and
Southern California Microwave, Inc., a California corporation (the
"Guaranteeing Subsidiaries"), each Guaranteeing Subsidiary (i) has jointly and
severally unconditionally guaranteed (a) the due and punctual payment of the
principal of, premium and interest on the Notes, whether at maturity or an
interest payment date, by acceleration, call for redemption or otherwise, (b)
the due and punctual payment of interest on the overdue principal and premium
of, and interest on the Notes, and (c) in case of any extension of time of
payment or renewal of any Notes or any of such other obligations, the same will
be promptly paid in full when due in accordance with the terms of the extension
or renewal, whether at stated maturity, by acceleration or otherwise and (ii)
has agreed to pay any and all costs and expenses (including reasonable
attorneys' fees) incurred by the Trustee or any Holder in enforcing any rights
under this Subsidiary Guarantee.

                  Notwithstanding the foregoing, in the event that the
Subsidiary Guarantee of any Guaranteeing Subsidiary would constitute or result
in a violation of any applicable fraudulent conveyance or similar law of any
relevant jurisdiction, the liability of such Guaranteeing Subsidiary under its
Subsidiary Guarantee shall be reduced to the maximum amount permissible under
such fraudulent conveyance or similar law.

                  No past, present or future director, officer, employee,
agent, incorporator, stockholder or agent of any Guaranteeing Subsidiary, as
such, shall have any liability for any obligations of the Company or any
Guaranteeing Subsidiary under the Notes, any Subsidiary Guarantee, Indenture,
any supplemental indenture delivered pursuant to the Indenture by such
Guaranteeing Subsidiary or any Subsidiary Guarantees, or for any claim based
on, in respect of or by reason of such obligations or their creation. Each
Holder by accepting a Note waives and releases all such liability.

                  This Subsidiary Guarantee shall be binding upon each
Guaranteeing Subsidiary and its successors and assigns and shall inure to the
benefit of the successors and assigns of the Trustee and the Holders and, in
the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges herein conferred upon that party shall automatically
extend to and be vested in such transferee or assignee, all subject to the
terms and conditions hereof.

                  This Subsidiary Guarantee shall not be valid or obligatory
for any purpose until the certificate of authentication on the Note upon which
this Subsidiary Guarantee is noted have been executed by the Trustee under the
Indenture by the manual signature of one of its authorized officers.
Capitalized terms used herein have the meaning assigned to them in the
Indenture.

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undersigned is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Old Notes that were acquired
as result of market-making activities or other trading activities, it
acknowledges that it will deliver a prospectus in connection with any resale of
such Exchange Notes; however, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. Any holder who is an
"affiliate" of the Company or who has an arrangement or understanding with
respect to the distribution of the Exchange Notes to be acquired pursuant to
the Exchange Offer, or any broker-dealer who purchased Old Notes from the
Company to resell pursuant to Rule 144A under the Securities Act or any other
available exemption under the Securities Act must comply with the registration
and prospectus delivery requirements under the Securities Act.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY


LADIES AND GENTLEMEN:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the above-described principal amount
of the Old Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of the Old Notes tendered herewith, the undersigned
hereby exchanges, assigns and transfers to, or upon the order of, the Company
all right, title and interest in and to such Old Notes. The undersigned hereby
irrevocably constitutes and appoints the Exchange Agent the true and lawful
agent and attorney-in-fact of the undersigned (with full knowledge that said
Exchange Agent acts as the agent of the Company, in connection with the
Exchange Offer) to cause the Old Notes to be assigned, transferred and
exchanged. The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the Old Notes and to acquire
Exchange Notes issuable upon the exchange of such tendered Old Notes, and that,
when the same are accepted for exchange, the Company will acquire good and
unencumbered title to the tendered Old Notes, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim.
The undersigned also warrants that it will, upon request, execute and deliver
any additional documents deemed by the Exchange Agent or the Company to be
necessary or desirable to complete the exchange, assignment and transfer of
tendered Old Notes or transfer ownership of such Old Notes on the account books
maintained by the book-entry transfer facility. The undersigned further agrees
that acceptance of any and all validly tendered Old Notes by the Company and
the issuance of Exchange Notes in exchange therefor shall constitute
performance in full by the Company of its obligations under the Registration
Rights Agreement (as defined in the Prospectus) and that the Company shall have
no further obligations or liabilities thereunder except as provided in the
first paragraph of Section 2 of said agreement.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Exchange Offer -- Certain Conditions to the
Exchange Offer." The undersigned recognizes that as a result of these
conditions (which may be waived, in whole or in part, by the Company), as more
particularly set forth in the Prospectus, the Company may not be required to
exchange any of the Old Notes tendered hereby and, in such event, the Old Notes
not exchanged will be returned to the undersigned at the address shown above.
In addition, the Company may amend the Exchange Offer at any time prior to the
Expiration Date if any of the conditions set forth under "The Exchange Offer --
Certain Conditions to the Exchange Offer" occur.

     By tendering, each holder of Old Notes represents that the Exchange Notes
acquired in the exchange will be obtained in the ordinary course of such
holder's business, that such holder has no arrangement with any person to
participate in the distribution of such Exchange Notes, that such holder is not
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act and that such holder is not engaged in, and does not intend to
engage in, a distribution of the Exchange Notes. Any holder of Old Notes using
the Exchange Offer to participate in a distribution of the Exchange Notes (i)
cannot rely on the position of the staff of the Securities and Exchange
Commission (the "Commission") enunciated in its interpretive letter with
respect to Exxon Capital Holdings Corporation (available April 13, 1989) or
similar letters and (ii) must comply with the registration and prospectus
requirements of the Securities Act in connection with a secondary resale
transaction.

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undersigned is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Old Notes that were acquired
as a result of market-making activities or other trading activities, it
acknowledges that it will deliver a prospectus in connection with any resale of
such Exchange Notes, however, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned and every obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned. Tendered Old Notes may be withdrawn at any time
prior to the Expiration Date in accordance with the terms of this Letter of
Transmittal. See Instruction 2.

     Certificates for all Exchange Notes delivered in exchange for tendered Old
Notes and any Old Notes delivered herewith but not exchanged, and registered in
the name of the undersigned, shall be delivered to the undersigned at the
address shown below the signature of the undersigned.

                                 INSTRUCTIONS


         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER


1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

     A holder of Old Notes may tender the same by (i) properly completing and
signing this Letter of Transmittal or a facsimile hereof (all references in the
Prospectus to the Letter of Transmittal shall be deemed to include a facsimile
thereof) and delivering the same, together with the certificate or certificates
representing the Old Notes being tendered and any required signature guarantees
and any other document required by this Letter of Transmittal, to the Exchange
Agent at its address set forth above on or prior to the Expiration Date (or
complying with the procedure for book-entry transfer described below) or (ii)
complying with the guaranteed delivery procedures described below.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE OLD NOTES AND
ANY OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER, AND
EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED MADE ONLY WHEN
ACTUALLY RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. IF SUCH DELIVERY IS BY
MAIL, IT IS SUGGESTED THAT REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERTY INSURED, BE USED. IN ALL CASES SUFFICIENT TIME SHOULD BE ALLOWED TO
PERMIT TIMELY DELIVERY. NO OLD NOTES OR LETTERS OF TRANSMITTAL SHOULD BE SENT
TO THE COMPANY.

     If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the Exchange Notes to be issued in exchange therefor
are to be issued (and any untendered Old Notes are to be reissued) in the name
of the registered holder (which term, for the purposes described herein, shall
include any participant in The Depository Trust Company (also referred to as a
"book-entry transfer facility") whose name appears on a security listing as the
owner of Old Notes), the signature of such signer need not be guaranteed. In
any other case, the tendered Old Notes must be endorsed or accompanied by
written instruments of transfer in form satisfactory to the Company and duly
executed by the registered holder, and the signature on the endorsement or
instrument of transfer must be guaranteed by a bank, broker, dealer, credit
union, savings association, clearing agency or other institution (each an
"Eligible Institution") that is a member of a recognized signature guarantee
medallion program within the meaning of Rule 17Ad-15 under the Securities
Exchange Act of 1934, as amended. If the Exchange Notes and/or Old Notes not
exchanged are to be delivered to an address other than that of the registered
holder appearing on the note register for the Old Notes, the signature on the
Letter of Transmittal must be guaranteed by an Eligible Institution.

     The Exchange Agent will make a request within two business days after the
date of receipt of this Prospectus to establish accounts with respect to the
Old Notes at the book-entry transfer facility for the purpose of facilitating
the Exchange Offer, and subject to the establishment thereof, any financial
institution that is a participant in the book-entry transfer facility's system
may make book-entry delivery of Old Notes by causing such book-entry transfer
facility to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with the book-entry transfer facility's
procedures for such transfer. Although delivery of Old Notes may be effected
through book-entry transfer into the Exchange Agent's account at the book-entry
transfer facility, an appropriate Letter of Transmittal with any required
signature guarantee and all other required documents must in each case be
transmitted to and received or confirmed by the Exchange Agent on or prior to
the Expiration Date, or, if the guaranteed delivery procedures described below
are complied with, within the time period provided under such procedures.

     If a holder desires to accept the Exchange Offer and time will not permit
a Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date or the procedure for book-entry transfer cannot be completed on
a timely basis, a tender may be effected if the Exchange Agent has received on
or prior to the Expiration Date, a letter, telegram or facsimile transmission
(receipt confirmed by telephone and an original delivered by guaranteed
overnight courier) from an Eligible Institution setting forth the name and
address of the tendering holder, the names in which the Old Notes are
registered and, if possible, the certificate numbers of the Old Notes to be
tendered, and stating that the tender is being made thereby and guaranteeing
that within three business days after the Expiration Date, the Old Notes in
proper form for transfer (or a confirmation of book-entry transfer of such Old
Notes into the Exchange Agent's account at the book-entry transfer facility),
will be delivered by such Eligible Institution together with a properly
completed and duly executed Letter of Transmittal (and any other required
documents). Unless Old Notes being tendered by the above-described method are
deposited with the Exchange Agent within the time period set forth above
(accompanied or preceded by a properly completed Letter of Transmittal and any
other required documents), the Company may, at its option, reject the tender.


                                       6
<PAGE>

Copies of the notice of guaranteed delivery ("Notice of Guaranteed Delivery")
which may be used by Eligible Institutions for the purposes described in this
paragraph are available from the Exchange Agent.

     A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at the book- entry transfer
facility) is received by the Exchange Agent, or (ii) a Notice of Guaranteed
Delivery or letter, telegram or facsimile transmission to similar effect (as
provided above) from an Eligible Institution is received by the Exchange Agent.
Issuances of Exchange Notes in exchange for Old Notes tendered pursuant to a
Notice of Guaranteed Delivery or letter, telegram or facsimile transmission to
similar effect (as provided above) by an Eligible Institution will be made only
against deposit of the Letter of Transmittal (and any other required documents)
and the tendered Old Notes.

     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear on the Old
Notes.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance
of the Old Notes for exchange.


2. PARTIAL TENDERS; WITHDRAWALS.

     If less than the entire principal amount of Old Notes evidenced by a
submitted certificate is tendered, the tendering holder should fill in the
principal amount tendered in the box entitled "Principal Amount Tendered." A
newly issued certificate for the principal amount of Old Notes submitted but
not tendered will be sent to such holder as soon as practicable after the
Expiration Date. All Old Notes delivered to the Exchange Agent will be deemed
to have been tendered unless otherwise clearly indicated.

     For a withdrawal to be effective, a written notice of withdrawal sent by
telegram, facsimile transmission (receipt confirmed by telephone) or letter
must be received by the Exchange Agent at the address set forth herein prior to
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having tendered the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number
or numbers and principal amount of such Old Notes), (iii) specify the principal
amount of Old Notes to be withdrawn, (iv) include a statement that such holder
is withdrawing his election to have such Old Notes exchanged, (v) be signed by
the holder in the same manner as the original signature on the Letter of
Transmittal by which such Old Notes were tendered or as otherwise described
above (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee under the Indenture
register the transfer of such Old Notes into the name of the person withdrawing
the tender and (vi) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. The Exchange Agent will
return the properly withdrawn Old Notes promptly following receipt of notice of
withdrawal. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the book-entry transfer facility to be credited with the
withdrawn Old Notes or otherwise comply with the book-entry transfer facility
procedure. All questions as to the validity of notices of withdrawals,
including, time of receipt, will be determined by the Company and such
determination will be final and binding on all parties.

     Any Old Notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the Exchange Offer. Any Old Notes which
have been tendered for exchange but which are not exchanged for any reason will
be returned to the holder thereof without cost to such holder (or, in the case
of Old Notes tendered by book-entry transfer into the Exchange Agent's account
at the book-entry transfer facility pursuant to the book-entry transfer
procedures described above, such Old Notes will be credited to an account with
such book-entry transfer facility specified by the holder) as soon as
practicable after withdrawal, rejection of tender or termination of the
Exchange Offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures described under the caption "Procedures for Tendering Old
Notes" in the Prospectus at any time on or prior to the Expiration Date.


3. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
 ENDORSEMENTS; GUARANTEE OF SIGNATURES.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Old Notes tendered hereby, the signature must correspond with the name(s)
written on the face of the certificates without alteration, enlargement or any
change whatsoever.


                                       7
<PAGE>

     If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

     If a number of Old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many separate copies of this
Letter of Transmittal as there are different registrations of Old Notes.

     When this Letter of Transmittal is signed by the registered holder or
holders (which term, for the purposes described herein, shall include the
book-entry transfer facility whose name appears on a security listing as the
owner of the Old Notes) of Old Notes listed and tendered hereby, no
endorsements of certificates or separate written instruments of transfer or
exchange are required.

     If this Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear(s) on the Old
Notes.

     If this Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority so
to act must be submitted.

     Endorsements on certificates or signatures on separate written instruments
of transfer or exchange required by this Instruction 3 must be guaranteed by an
Eligible Institution.

     Signatures on this Letter of Transmittal need not be guaranteed by an
Eligible Institution, provided the Old Notes are tendered: (i) by a registered
holder of such Old Notes, for the holder of such Old Notes; or (ii) for the
account of an Eligible Institution.


4.  TRANSFER TAXES.

     The Company shall pay all transfer taxes, if any, applicable to the
transfer and exchange of Old Notes pursuant to the Exchange Offer. If, however,
certificates representing Exchange Notes or Old Notes for principal amounts not
tendered or accepted for exchange are to be delivered to, or are to be issued
in the name of, any person other than the registered holder of the Old Notes
tendered, or if tendered Old Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax
is imposed for any reason other than the exchange of Old Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exception
therefrom is not submitted herewith the amount of such transfer taxes will be
billed directly to such tendering holder.

     Except as provided in this Instruction 4, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.


5. WAIVER OF CONDITIONS.

     The Company reserves the right to waive in its reasonable judgment, in
whole or in part, any of the conditions to the Exchange Offer set forth in the
Prospectus.


6. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.

     Any holder whose Old Notes have been mutilated, lost, stolen or destroyed,
should contact the Exchange Agent at the address indicated above for further
instructions.


7. SUBSTITUTE FORM W-9.

     Each holder of Old Notes whose Old Notes are accepted for exchange (or
other payee) is required to provide a correct taxpayer identification number
("TIN"), generally the holder's Social Security or federal employer
identification number, and with certain other information, on Substitute Form
W-9, which is provided under "Important Tax Information" below, and to certify
that the holder (or other payee) is not subject to backup withholding. Failure
to provide the information on the Substitute Form W-9 may subject the holder
(or other payee) to a $50 penalty imposed by the Internal Revenue Service and
31% federal income tax backup withholding on payments made in connection with
the Exchange Notes. The box in Part 3


                                       8
<PAGE>

of the Substitute Form W-9 may be checked if the holder (or other payee) has
not been issued a TIN and has applied for a TIN or intends to apply for a TIN
in the near future. If the box in Part 3 is checked and a TIN is not provided
by the time any payment is made in connection with the Exchange Notes, 31% of
all such payments will be withheld until a TIN is provided.


8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal, may be
directed to the Exchange Agent at the address and telephone number set forth
above. In addition, all questions relating to the Exchange Offer, as well as
requests for assistance or additional copies of the Prospectus and this Letter
of Transmittal, may be directed to L-3 Communications Corporation, 600 Third
Avenue, New York, New York 10016, attention: Corporate Secretary (telephone:
(212) 697-1111).

     IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE HEREOF (TOGETHER WITH
CERTIFICATES FOR OLD NOTES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER
REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE
EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.


                           IMPORTANT TAX INFORMATION

     Under U.S. federal income tax law, a holder of Old Notes whose Old Notes
are accepted for exchange may be subject to backup withholding unless the
holder provides The Bank of New York (as payor) (the "Paying Agent"), through
the Exchange Agent, with either (i) such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 attached hereto,
certifying that the TIN provided on Substitute Form W-9 is correct (or that
such holder of Old Notes is awaiting a TIN) and that (A) the holder of Old
Notes has not been notified by the Internal Revenue Service that he or she is
subject to backup withholding as a result of a failure to report all interest
or dividends or (B) the Internal Revenue Service has notified the holder of Old
Notes that he or she is no longer subject to backup withholding; or (ii) an
adequate basis for exemption from backup withholding. If such holder of Old
Notes is an individual, the TIN is such holder's social security number. If the
Paying Agent is not provided with the correct taxpayer identification number,
the holder of Old Notes may be subject to certain penalties imposed by the
Internal Revenue Service.

     Certain holders of Old Notes (including, among others, all corporations
and certain foreign individuals) are not subject to these backup withholding
and reporting requirements. Exempt holders of Old Notes should indicate their
exempt status on Substitute Form W-9. In order for a foreign individual to
qualify as an exempt recipient, the holder must submit a Form W-8, signed under
penalties of perjury, attesting to that individual's exempt status. A Form W-8
can be obtained from the Paying Agent. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
more instructions.

     If backup withholding applies, the Paying Agent is required to withhold
31% of any such payments made to the holder of Old Notes or other payee. Backup
withholding is not an additional tax. Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.

     The box in Part 3 of the Substitute Form W-9 may be checked if the
surrendering holder of Old Notes has not been issued a TIN and has applied for
a TIN or intends to apply for a TIN in the near future. If the box in Part 3 is
checked, the holder of Old Notes or other payee must also complete the
Certificate of Awaiting Taxpayer Identification Number below in order to avoid
backup withholding. Notwithstanding that the box in Part 3 is checked and the
Certificate of Awaiting Taxpayer Identification Number is completed, the Paying
Agent will withhold 31% of all payments made prior to the time a properly
certified TIN is provided to the Paying Agent.

     The holder of Old Notes is required to give the Paying Agent the TIN
(e.g., social security number or employer identification number) of the record
owner of the Old Notes. If the Old Notes are in more than one name or are not
in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

 has not been issued to me, and either (1) I have mailed or delivered an
 application to receive a taxpayer identification number to the appropriate
 Internal Revenue Service Center or Social Security Administration Office or
 (2) I intend to mail or deliver an application in the near future. I
 understand that if I do not provide a taxpayer identification number by the

 will be withheld until I provide a taxpayer identification number.
