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, pro forma EBITDA (as defined in footnote 8 under "Selected
Financial Information") of $148.4 million, pro forma net income of $26.5
million and pro forma diluted earnings per common share of $0.93. 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,


                                       1
<PAGE>

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 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


                                       2
<PAGE>

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, 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:


                                       3
<PAGE>

      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.

      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
eleven additional businesses for an aggregate cash purchase price including
expenses, net of cash acquired, of $444.0 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,
high-speed transfer switches, fault isolation units, frequency converters and
inverters, voltage transformers and uninterruptible power supply systems. SPD's
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 our bank credit
facilities.

     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


                                       4
<PAGE>

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 commenced a cash tender offer for all of the common stock of
Microdyne. This acquisition is subject to the receipt of a majority of the
outstanding shares of Microdyne's common stock and the approval of our lenders,
regulatory approvals and other customary closing conditions. Microdyne's largest
stockholder has agreed to tender his shares, which amount to approximately 43%
of the total shares outstanding, in the tender offer. We expect to close the
transaction 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. It is expected that the acquisition will be
financed using cash from operations and borrowings under our bank credit
facilities. See "Management's Discussion and Analysis of Results of Operations
and Financial Condition -- Liquidity and Capital Resources".

 (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
     ($0.22 per share) 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, cash interest expense consists of pro
     forma interest expense less amortization of deferred debt issuance costs.
       

 (9) 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.

(10) 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 in this prospectus before investing in shares of common
stock.


WE HAVE A SIGNIFICANT AMOUNT OF DEBT

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


                                       9
<PAGE>

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 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".
Although we have signed an agreement to acquire all of the outstanding common
stock of Microdyne, we cannot assure you that the acquisition will be
completed.


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.

                                       10
<PAGE>

     All of our U.S. government contracts can be terminated 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.


                                       11
<PAGE>

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.


                                       12
<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,


                                       13
<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 Board 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 Communications Corporation, 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 Communications
Corporation 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 these plans to it if Lockheed Martin has
concluded that the liabilities of the Subject Plans would increase
unreasonably. L-3 Communications Corporation has 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. L-3 Communications Corporation has
notified Lockheed Martin of this fact. We have not yet received a response as
to whether Lockheed Martin will exercise its right to cause L-3 Communications
Corporation 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 these plans or any costs associated with the
termination of the Subject Plans, but L-3 Communications Corporation would be
required to reimburse Lockheed Martin for these costs. See "Business -- Pension
Plans". We expect, based in part upon discussions with our consulting
actuaries, that any increase in pension expenses or future funding requirements
from those previously anticipated for the pension plans would not be material.
However, the impact of any increased pension expenses or funding requirements
under this arrangement or the cost to us of any reimbursement of Lockheed
Martin (if these plans were terminated) could be material to us.


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

     As described in "Use of Proceeds", we intend to use the net proceeds of
this offering to repay a substantial portion of our existing indebtedness under
our bank credit facilities. Upon repayment, our borrowing capacity under our
bank credit facilities will be restored and we will have wide discretion over
the use of any funds subsequently reborrowed under our bank credit facilities.
Should the acquisition of Microdyne close, we expect to use our existing cash
balances and to borrow under our bank credit facilities to fund that
acquisition.


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;

                                       14
<PAGE>

      o  repurchase or redeem capital stock;

      o  engage in mergers or consolidations; and

      o  engage in certain transactions with subsidiaries and affiliates.

     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".


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;


                                       15
<PAGE>

     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.


L-3'S OWNERSHIP IS CONCENTRATED

     After this offering, the Lehman Partnership will own 26.0% of the
outstanding voting stock of L-3 (or 24.8% if the underwriters' over-allotment
option is exercised in full). As a result of such ownership and its significant
voting power with respect to actions requiring stockholder approval, the Lehman
Partnership will have the power to influence the business and affairs of L-3.
The concentrated ownership of L-3 may:

     o   prevent L-3 from being acquired in a transaction not supported by its
         principal stockholders;

     o   discourage a proposed merger or tender offer or make it more difficult
         to complete; and

     o   prevent a successful proxy contest.

     See "Ownership of Capital Stock".


THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY

     A number of factors could cause the market price of our common stock to
fluctuate substantially including:

     o   quarterly operating results of L-3 or other similar companies;

     o   changes in general conditions in the economy, the financial markets or
         the defense industry;

     o   natural disasters;

     o   changes in earnings estimates or recommendations by research analysts;
         and

     o   other developments affecting us or our competitors.

     In recent years, the stock market has experienced extreme price and volume
fluctuations. This volatility has had a significant effect on the market prices
of securities issued by many companies for reasons unrelated to the operating
performance of these companies. See "Underwriting".


A NUMBER OF SHARES ARE OR WILL BE AVAILABLE FOR FUTURE SALE

     As of December 31, 1998, there were 27,402,429 shares of common stock
outstanding. After this offering, certain holders of shares of common stock
issued prior to this offering will be entitled to the registration rights
described below, at the expense of L-3. Such shares may also be sold under Rule
144 of the Securities Act, depending on how long they have been held and
subject to restrictions in the case of shares held by affiliates of L-3. We
cannot predict the effect, if any, that future sales of shares, or the
availability of shares for future sale, will have on the market price of the
common stock. Sales of substantial amounts of common stock (including shares
issued upon the exercise of stock options), or the perception that such sales
could occur, may lower the market price for the common stock.

     Messrs. Lanza and LaPenta, Lockheed Martin and the Lehman Partnership who,
after this offering, will hold in the aggregate 14,471,142 shares of common
stock, and Holdings have agreed, that they will not, without the prior written
consent of Lehman Brothers Inc., dispose of any shares of common stock or
securities exercisable or exchangeable for common stock or enter into any
derivative transaction with a similar effect for a period of     days after the
date of this prospectus. The restrictions described in this paragraph do not
apply to:


     o   the sale of common stock to the underwriters in this offering;


     o   the issuance by L-3 of shares of common stock upon the exercise of an
         option or a warrant or the conversion of a security outstanding on the
         date of this prospectus; and


     o   transactions by any person other than L-3 relating to shares of common
         stock or other securities acquired in the market after the completion
         of this offering.


     Pursuant to a stockholders agreement, Messrs. Lanza and LaPenta, Lockheed
Martin, the Lehman Partnership and certain other existing stockholders have the
right, under certain circumstances and subject to certain conditions, to
require L-3 to register their shares of common stock under the Securities Act.
Lockheed Martin has three demand registration rights (two of which the Company
must pay for), the Lehman Partnership has four (three of which the Company must
pay for) and Mr. Lanza and Mr. LaPenta each have one (which the Company must
pay for). In addition, each of these shareholders may include a certain portion
of their shares (at the Company's expense) in a registration which L-3
initiates.


CERTAIN FACTORS MAY DELAY OR PREVENT A CHANGE OF CONTROL TRANSACTION


     Certain provisions of Delaware corporate law and of our charter and
by-laws, in addition to the concentration of ownership in the Lehman
Partnership and Lockheed Martin, may have the effect of discouraging a third
party from trying to acquire L-3. Moreover, these factors could delay or
prevent a transaction or a change in control of L-3 under circumstances that
could otherwise give the holders of common stock the opportunity to sell their
shares for a premium. Certain provisions of Delaware corporate law and of the
Company's charter and by-laws have the effect of making it more difficult to
acquire control of L-3 in a transaction that the board of directors has not
approved. These provisions include the three-class board of directors and the
ability to issue preferred stock. See "Description of Capital Stock".

                                USE OF PROCEEDS


     The net proceeds to the Company from this offering are estimated to be
approximately $149.7 million ($209.5 million if the underwriters'
over-allotment option is exercised in full) based on the closing price per
share of the common stock on December 28, 1998 of $44.625 and after deducting
underwriting discounts and commissions and other estimated offering expenses.


     The Company intends to use the net proceeds of this offering to repay the
existing indebtedness, if any, under the Senior Credit Facilities (as defined
later in this prospectus) and for general corporate purposes, including
potential acquisitions. The borrowings under the Senior Credit Facilities were
used by the Company to fund in part the L-3 Acquisition and the 1998
Acquisitions. The weighted average interest rate under the Senior Credit
Facilities was 7.331% at September 30, 1998. Amounts repaid under the Senior
Credit Facilities will be available to be reborrowed by the Company from time
to time for, among other reasons, general corporate purposes or to finance
future acquisitions. See "Risk Factors--We Have Discretion Over the use of
Funds Raised in the Offering". Affiliates of the underwriters are lenders under
the Senior Credit Facilities and will receive a portion of the net proceeds of
this offering in repayment of amounts outstanding thereunder. See "Description
of Certain Indebtedness -- Senior Credit Facilities". The Company will not
receive any of the proceeds from the shares being sold by the selling
stockholders.



                                DIVIDEND POLICY


     Holdings currently intends to retain its earnings to finance future growth
and, therefore, does not anticipate paying any cash dividends on its common
stock in the foreseeable future. Any determination as to the payment of
dividends will depend upon the future results of operations, capital
requirements and financial condition of Holdings and its subsidiaries and such
other facts as the Board of Directors of Holdings may consider, including any
contractual or statutory restrictions on Holdings' ability to pay dividends.
Moreover, Holdings is a holding company and its ability to pay dividends is
dependent upon receipt of dividends, distributions, advances, loans or other
cash transfers from L-3 Communications Corporation. Certain outstanding debt
instruments of L-3 Communications Corporation limit its ability to pay
dividends or other distributions on its common stock or to make advances, loans
or other cash transfers to Holdings. See "Description of Certain Indebtedness".

       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 Notes Offering in which L-3
Communications Corporation sold $200.0 million of 8% Senior Subordinated Notes
due August 1, 2008 (the "December 1998 Notes"), the net proceeds of which
amounted to $192.8 million after debt issuance costs; (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, Inc. ("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 IPO, the net proceeds of which amounted to $139.5 million and the sale by
L-3 Communications Corporation of $180.0 million of 8 1/2% Senior Subordinated
Notes due May 15, 2008 (the "May 1998 Notes"), the net proceeds of which
amounted to $173.8 million after debt issuance costs, and the amendment of L-3
Communications Corporation'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 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 this offering or to any of the
Company's other acquisitions, including the pending 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.

5. On June 30, 1997, SPD acquired all of the outstanding stock of PPI and
   subsidiaries. The PPI acquisition was financed principally by SPD bank
   borrowings. SPD accounted for the PPI acquisition as a purchase and the
   results of operations of PPI are included in the consolidated SPD
   historical financial statements from the date of acquisition. The
   adjustments related to SPD's financing of its PPI acquisition and the
   related purchase price allocation are included in the pro forma

6. The Financing Transactions included (i) the proceeds from the sale by
   Holdings of 6.9 million shares of its 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 L-3 Communications Corporation
   of the May 1998 Notes, whose proceeds amounted to $173.8 million after
   debt issuance costs of $6.2 million and (iii) the amendment of L-3
   Communications Corporation'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 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.

   The Notes Offering was completed on December 11, 1998. The pro forma
   statements of operations do not reflect interest income on the $43.5
   million pro forma cash balance at September 30, 1998 after the Notes
   Offering.


9.  The pro forma adjustments for the Notes Offering to the balance sheet as of
    September 30, 1998, include (i) a net increase to long-term debt of $45.0
    million reflecting the $200.0 million of December 1998 Notes issued in the
    Notes Offering, and the repayment of $155.0 million of borrowings
    outstanding under the Senior Credit Facilities with the net proceeds of
    the December 1998 Notes, (ii) an increase of $7.2 million to other assets
    representing the bond discount of $0.6 million and underwriting discounts
    and commissions and other estimated expenses associated with the Notes
    Offering of $6.6 million which will be deferred and amortized to interest
    expense over the term of the December 1998 Notes and (iii) an increase to
    cash and cash equivalents of $37.8 million representing the remaining net
    proceeds after the repayment of the borrowings outstanding under the
    Senior Credit Facilities and the payment of the bond discount,
    underwriting discounts and commissions and other estimated expenses
    associated with the Notes Offering.


10. The pro forma adjustments were tax-effected, as appropriate, using a
    statutory (federal, state and foreign) tax rate of 39.0%.

11. Pro forma basic earnings per common share are computed based upon the
    weighted-average shares of common stock outstanding. Pro forma diluted
    earnings per common stock are computed based upon: (a) the weighted
    average shares of common stock and potential common stock outstanding, to
    the extent the potential common stock is not anti-dilutive, giving effect
    to the IPO; and (b) an assumed average market price of common stock for
    all periods between January 1, 1997 and December 31, 1997 of $22.00 per
    share based on the IPO price and of $28.64 per share for the nine months
    ended September 30, 1998 based on the IPO price of $22.00 for the period
    January 1, 1998 to May 19, 1998 (the date of the IPO) and actual average
    market prices of Holdings' common stock for the period May 20, 1998 to
    September 30, 1998, were used for the assumed purchase of common shares
    for treasury.

(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 ($0.22
     per share) 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
     ($0.22 per share) 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, cash interest expense consists of pro
     forma interest expense excluding amortization of deferred debt issuance
     costs.

(10) 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.

(11) 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. 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.


                                       33
<PAGE>

     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, and additional consideration based on the
post-acquisition performance of DBS. The acquisition was financed with
borrowings under the Senior Credit Facilities.

     On December 17, 1998, L-3 Communications 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 commenced a cash tender offer for all of the common stock of Microdyne.
This acquisition is subject to the receipt of a majority of the outstanding
shares of Microdyne's common stock and the approval of the Company's lenders,
regulatory approvals and other customary closing conditions. Microdyne's
largest stockholder has agreed to tender his shares, which amount to
approximately 43% of the total shares outstanding, in the tender offer.
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.
It is expected that the acquisition will be financed using cash from operations
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 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

      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.


     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 ($0.22 per
share) 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 ($0.22 per share) 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 ($0.22 per
share) 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


                                       37
<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


                                       38
<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 ($0.22 per share) 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 L-3 Communications Corporation 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 L-3 Communications
Corporation's Revolving Credit Facility, increased borrowings available to L-3
Communications Corporation, 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 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 December 1998 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 Corporation. The financial covenants under the Senior Credit
Facilities require that (i) L-3 Communications Corporation's 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, as defined, 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 Corporation's
interest coverage ratio, as defined therein, be at least 2.00 for the quarter
ended September 30, 1998 and thereafter increase over time the interest
coverage ratio, as defined, to at least 3.00 for any fiscal quarters ending
September 30, 2002 and thereafter. As of September 30, 1998, L-3 Communications
Corporation 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 1997 Notes, the May 1998 Notes and the
December 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 Offering".


                                       40
<PAGE>

     L-3 Communications Corporation's indebtedness under the Senior Credit
Facilities is guaranteed by many of its subsidiaries and by Holdings. 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 December 1998 Notes is unconditionally guaranteed, on an
unsecured senior subordinated basis, jointly and severally, by many of L-3
Communications Corporation'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.

     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.

     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. Concurrent with the IPO, L-3 Communications
Corporation 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 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.


                                       42
<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 equity of $125.0 million was comprised of $80.0
million in cash contributed by the Lehman Partnership and Senior Management and
a $45.0 million retained interest 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, L-3 Communications Corporation
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 10
3/8% Senior Subordinated Notes of L-3 Communications Corporation (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


                                       43
<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


                                       44
<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.

    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 and 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


                                       47
<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:

      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


                                       52
<PAGE>

   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.

      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


                                       53
<PAGE>

   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 eleven additional businesses for an aggregate cash purchase price
including expenses, net of cash acquired, of $444.0 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 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


                                       54
<PAGE>

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 commenced a cash tender offer for all of the common stock of
Microdyne. This acquisition is subject to the receipt of a majority of the
outstanding shares of Microdyne's common stock and the approval of our lenders,
regulatory approvals and other customary closing conditions. Microdyne's
largest stockholder has agreed to tender his shares, which amount to
approximately 43% of the total shares outstanding, in the tender offer. We
expect to close the transaction 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. It is expected that the
acquisition will be financed using cash from operations and borrowings under
the bank credit facilities. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition -- Liquidity and Capital
Resources".

                                       57
<PAGE>

is working and whether the base station radios are operating at peak power
levels. 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

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 significantly 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.

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  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"). 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.


                                       61
<PAGE>

     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 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.


                                       62
<PAGE>

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


                                       63
<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.

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.

     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%


                                       64
<PAGE>

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
Corporation 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
Corporation. 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 Communications Corporation and the PBGC dated as of April 30, 1997. The
material terms and conditions of the Lockheed Martin Commitment Agreement
include a 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


                                       65

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, L-3 Communications
Corporation entered into an agreement with Lockheed Martin, dated as of April
30, 1997, pursuant to which L-3 Communications Corporation 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 increase in the
underlying liability, one of such triggering events has occurred. L-3
Communications Corporation has notified Lockheed Martin of this fact. The
Company has not yet received a response as to whether Lockheed Martin will
exercise its right to cause L-3 Communications Corporation 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 L-3 Communications Corporation would be required to reimburse
Lockheed Martin for these costs. The Company expects, based in part upon
discussions with its consulting actuaries, that any increase in pension
expenses or future funding requirements from those previously anticipated for
the pension plans would not be material. However notwithstanding this
expectation, the impact of any increased pension expenses or funding
requirements under this arrangement 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 September 30, 1998, the Company employed approximately 7,800
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


                                       66
<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 Corporation 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, certain of the existing
stockholders 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 other things, that the Company will pay


                                       68
<PAGE>

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%.

     The Company's certificate of incorporation provides for a classified Board
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
Board of Directors or committees thereof. In addition, the non-affiliated
directors will be compensated $1,000 per meeting attended, including committee
meetings, up to a maximum of $2,000 per day.

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 Corporation. 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 will
hold 26.0% of the Holdings common stock after this offering (or 24.8% if the
underwriters' over-allotment option is exercised in full) 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 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 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 Corporation 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
which 3,402,784 had been granted 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 285,370 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
 


                                       77
<PAGE>

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 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.

PRINCIPAL STOCKHOLDERS


     As of December 31, 1998, there were 27,402,429 shares of Holdings' common
stock outstanding. The following table sets forth as of September 30, 1998

                         DESCRIPTION OF CAPITAL STOCK


GENERAL

     The current certificate of incorporation of Holdings authorizes
100,000,000 shares of common stock. As of December 31, 1998, the outstanding
capital stock of Holdings consisted of 27,402,429 shares of common stock held
by 85 stockholders of record. The following summaries of certain provisions of
the common stock do not purport to be complete and are subject to, and
qualified in their entirety by, the provisions of the certificate of
incorporation and bylaws of Holdings, which are included as exhibits to the
Registration Statement of which this prospectus forms a part, and by applicable
law.


COMMON STOCK

     Holders of common stock are entitled to one vote per share on all matters
to be voted upon by the stockholders of Holdings, and do not have cumulative
voting rights. The holders of common stock are entitled to receive ratably such
dividends, if any, as may be declared from time to time by the Board of
Directors out of funds legally available for that purpose, subject to
preferences that may be applicable to any outstanding preferred stock and any
other provisions of Holdings' certificate of incorporation. Holdings does not,
however, anticipate paying any cash dividends in the foreseeable future.
Holders of common stock have no preemptive or other rights to subscribe for
additional shares. No shares of common stock are subject to redemption or a
sinking fund. In the event of any liquidation, dissolution or winding up of
Holdings, after payment of the debts and other liabilities of Holdings, and
subject to the rights of holders of shares of preferred stock, holders of
common stock are entitled to share pro rata in any distribution to the
stockholders. All of the outstanding shares of common stock are, and the shares
offered hereby will be, fully paid and nonassessable. See "Risk Factors --
L-3's Ownership is Concentrated", "Dividend Policy" and "Shares Eligible for
Future Sale".


PREFERRED STOCK

     The Board of Directors is authorized, without further vote or action by
holders of common stock, to issue 25,000,000 shares of preferred stock in one
or more series and to designate the rights, preferences, limitations,
restrictions of and upon shares of each series, including voting, redemption
and conversion rights. The Board of Directors may also designate dividend
rights and preferences in liquidation. It is not possible to state the effect
of the authorization and issuance of any series of preferred stock upon the
rights of the holders of common stock until the Board of Directors determines
the specific terms, rights and preferences of such a series of preferred stock.
However, such effects might include, among other things, restricting dividends
on the common stock, diluting the voting power of the common stock or impairing
the liquidation rights of such shares without further action by holders of
common stock. In addition, under certain circumstances, the issuance of
preferred stock may render more difficult or tend to discourage a merger,
tender offer or proxy contest, the assumption of control by a holder of a large
block of Holdings' securities or the removal of incumbent management, which
could thereby depress the market price of Holdings' common stock.


SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

     Holdings is a Delaware corporation subject to Section 203 of the DGCL
("Section 203"). Section 203 provides in general that a stockholder acquiring
more than 15% of the outstanding voting stock of a corporation subject to
Section 203 (an "Interested Stockholder") but less than 85% of such stock may
not engage in certain Business Combinations (as defined in Section 203) with
the corporation for a period of three years subsequent to the date on which the
stockholder became an Interested Stockholder unless (i) prior to such date the
corporation's board of directors approved either the Business Combination or
the transaction in which the stockholder became an Interested Stockholder or
(ii) the Business Combination is approved by the corporation's board of
directors and authorized by a vote of at least 66 2/3% of the outstanding
voting stock of the corporation not owned by the Interested Stockholder. A
"Business Combination" includes mergers, asset sales and other transactions
resulting in financial benefit to a stockholder. Section 203 could prohibit or
delay mergers or other takeover or change of control attempts with respect to
the Company and, accordingly, may discourage attempts that might result in a
premium over the market price for the shares held by stockholders.


TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is First Chicago
Trust Company of New York.

                      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 Corporation 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 Corporation's 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 L-3 Communications Corporation'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 L-3 Communications Corporation'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 Corporation 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
L-3 Communications Corporation'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 Corporation 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 L-3 Communications Corporation's
ratio of debt to Bank EBITDA at the time of determination. L-3 Communications
Corporation 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 Corporation 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


                                       81

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

     The Senior Credit Facilities contain customary covenants and restrictions
on L-3 Communications Corporation's ability to engage in certain activities. In
addition, the Senior Credit Facilities provide that L-3 Communications
Corporation 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.

GENERAL

     Upon the consummation of this offering, Holdings will have 30,902,429
shares of common stock issued and outstanding. All of the 9,250,000 shares of
common stock to be sold in this offering (and any shares sold upon exercise of
the underwriters' over-allotment option) will be freely tradable without
restrictions or further registration under the Securities Act, except for any
shares purchased by an "affiliate" of Holdings (as that term is defined in Rule
144 under the Securities Act ("Rule 144")), which will be subject to the resale
limitations of Rule 144. After the completion of this offering, the Company
will have 14,707,142 shares of common stock outstanding which are "restricted
securities" as that term is defined in Rule 144 and are also subject to certain
restrictions on disposition. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rule 144 or Rule 701 under the Securities Act. Sales of restricted
securities in the public market, or the availability of such shares for sale,
could have an adverse effect on the price of the Common Stock. See "Risk
Factors -- The Price of our Common Stock may Fluctuate Significantly" and "Risk
Factors -- A Number of Shares are or Will be Available for Future Sale".


                                       86
<PAGE>

RULE 144


     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are required to be aggregated) who has beneficially owned shares
of common stock for at least one year, including a person who may be deemed an
"affiliate" of Holdings, is entitled to sell, within any three-month period, a
number of shares that does not exceed the greater of 1% of the total number of
shares of the class of stock sold or the average weekly reported trading volume
of the class of stock being sold during the four calendar weeks preceding such
sale. A person who is not deemed an "affiliate" of Holdings at any time during
the three months preceding a sale and who has beneficially owned shares for at
least two years is entitled to sell such shares under Rule 144 without regard
to the volume limitations described above. As defined in Rule 144, an
"affiliate" of an issuer is a person that directly or indirectly through the
use of one or more intermediaries controls, is controlled by, or is under
common control with, such issuer. The foregoing summary of Rule 144 is not
intended to be a complete description thereof.


     Messrs. Lanza and LaPenta, Lockheed Martin and the Lehman Partnership who,
after this offering, will hold in the aggregate 14,471,142 shares of common
stock, and Holdings have agreed, pursuant to lock-up agreements, that they will
not, without the prior written consent of Lehman Brothers Inc., offer, sell,
contract to sell or otherwise dispose of any shares of common stock or
securities exercisable or exchangeable for common stock or enter into any
derivative transaction with similar effect as a sale of common stock for a
period of     days after the date of this prospectus. The restrictions
described in this paragraph do not apply to (i) the sale of common stock to the
underwriters in this offering, (ii) the issuance by Holdings of shares of
common stock upon the exercise of an option or a warrant or the conversion of a
security outstanding on the date of this prospectus or (iii) transactions by
any person other than Holdings relating to shares of common stock or other
securities acquired in open market transactions after the completion of this
offering of the common stock.

respectively. In addition, the Stockholders Agreement also provides all of the
existing stockholders with certain piggyback registration rights. The
Stockholders Agreement provides, among 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

               CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS

     The following summary accurately describes certain United States federal
income and estate tax consequences that may be relevant to the purchase,
ownership and disposition of common stock by a Non-U.S. Holder. For this
purpose, a "Non-U.S. Holder" is any person who is, for United States federal
income tax purposes, a foreign corporation, a non-resident alien individual, a
foreign partnership or a foreign estate or trust. This discussion does not
address all aspects of United States federal income and estate taxes and does
not deal with foreign, state and local consequences that may be relevant to
such Non-U.S. Holders in light of their personal circumstances. Furthermore,
this discussion is based on provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), existing and proposed regulations promulgated thereunder
and administrative and judicial interpretations thereof, as of the date hereof,
all of which are subject to change. EACH PROSPECTIVE PURCHASER OF COMMON STOCK
IS ADVISED TO CONSULT A TAX ADVISOR WITH RESPECT TO CURRENT AND POSSIBLE FUTURE
TAX CONSEQUENCES OF ACQUIRING, HOLDING AND DISPOSING OF COMMON STOCK AS WELL AS
ANY TAX CONSEQUENCES THAT MAY ARISE UNDER THE LAWS OF ANY U.S. STATE,
MUNICIPALITY OR OTHER TAXING JURISDICTION.


DIVIDENDS

     Dividends paid to a Non-U.S. Holder of common stock generally will be
subject to withholding of United States federal income tax at a 30% rate or
such lower rate as may be specified by an applicable income tax treaty.
However, dividends that are effectively connected with the conduct of a trade
or business by the Non-U.S. Holder within the United States and, where a tax
treaty applies, are attributable to a United States permanent establishment of
the Non-U.S. Holder, are not subject to the withholding tax, but instead are
subject to United States federal income tax on a net income basis at applicable
graduated individual or corporate rates. Certain certification and disclosure
requirements must be complied with in order to be exempt from withholding under
such effectively connected income exemption. Any such effectively connected
dividends received by a foreign corporation may be subject to an additional
"branch profits tax" at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty.

     Until December 31, 1999, dividends paid to an address outside the United
States are presumed to be paid to a resident of such country (unless the payer
has knowledge to the contrary) for purposes of the withholding tax discussed
above and, under the current interpretation of United States Treasury
regulations, for purposes of determining the applicability of a tax treaty
rate. However, a Non-U.S. Holder of common stock who wishes to claim the
benefit of an applicable treaty rate (and avoid back-up withholding as
discussed below) for dividends paid after December 31, 1999, will be required
to satisfy applicable certification and other requirements.

     A Non-U.S. Holder of common stock eligible for a reduced rate of United
States withholding tax pursuant to an income tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
Internal Revenue Service (the "IRS").


GAIN ON DISPOSITION OF COMMON STOCK

     A Non-U.S. Holder generally will not be subject to United States federal
income tax with respect to gain recognized on a sale or other disposition of
common stock unless (i) the gain is effectively connected with a trade or
business of the Non-U.S. Holder in the United States, and, where a tax treaty
applies, is attributable to a United States permanent establishment of the
Non-U.S. Holder, (ii) in the case of a Non-U.S. Holder who is an individual and
holds the common stock as a capital asset, such holder is present in the United
States for 183 or more days in the taxable year of the sale or other
disposition and certain other conditions are met, or (iii) the Company is or
has been a "U.S. real property holding corporation" for United States federal
income tax purposes.

     An individual Non-U.S. Holder described in clause (i) above will be
subject to tax on the net gain derived from the sale under regular graduated
United States federal income tax rates. An individual Non-U.S. Holder described
in clause (ii) above will be subject to a flat 30% tax on the gain derived from
the sale, which may be offset by United States source capital losses (even
though the individual


                                       88
<PAGE>

is not considered a resident of the United States). If a Non-U.S. Holder that
is a foreign corporation falls under clause (i) above, it will be subject to
tax on its gain under regular graduated United States federal income tax rates
and, in addition, may be subject to the branch profits tax equal to 30% of its
effectively connected earnings and profits within the meaning of the Code for
the taxable year, as adjusted for certain items, unless it qualifies for a
lower rate under an applicable income tax treaty. The Company believes it is
not, and does not anticipate becoming, a "U.S. real property holding
corporation" for United States federal income tax purposes.


FEDERAL ESTATE TAX


     Common stock held by an individual Non-U.S. Holder at the time of death
will be included in such holder's gross estate for United States federal estate
tax purposes, unless an applicable estate tax treaty provides otherwise.


INFORMATION REPORTING AND BACKUP WITHHOLDING


     The Company must report annually to the IRS and to each Non-U.S. Holder
the amount of dividends paid to such Non-U.S. Holder and the tax withheld with
respect to such dividends, regardless of whether withholding was required.
Copies of the information returns reporting such dividends and withholding may
also be made available to the tax authorities in the country in which the
Non-U.S. Holder resides under the provisions of an applicable income tax
treaty.


     Under current law, backup withholding at the rate of 31% generally will
not apply to dividends paid to a Non-U.S. Holder at an address outside the
United States (unless the payer has knowledge that the payee is a U.S. person).
Under the Final Regulations, however, a Non-U.S. Holder will be subject to
back-up withholding unless applicable certification requirements are met.


     Payment of the proceeds of a sale of common stock by or through a United
States office of a broker is subject to both backup withholding and information
reporting unless the beneficial owner certifies under penalties of perjury that
it is a Non-U.S. Holder or otherwise establishes an exemption. In general,
backup withholding and information reporting will not apply to a payment of the
proceeds of a sale of common stock by or through a foreign office of a broker.
If, however, such broker is, for United States federal income tax purposes a
U.S. Person, a controlled foreign corporation, or a foreign person that derives
50% or more of its gross income for a certain period from the conduct of a
trade or business in the United States or for taxable years beginning after
December 31, 1999, a foreign partnership, in which one or more U.S. Persons, in
the aggregate, own more than 50% of the income or capital interests in the
partnership or which is engaged in a trade or business in the United States,
such payments will be subject to information reporting, but not backup
withholding, unless (i) such broker has documentary evidence in its records
that the beneficial owner is a Non-U.S. Holder and certain other conditions are
met, or (ii) the beneficial owner otherwise establishes an exemption.


     Any amounts withheld under the backup withholding rules may be allowed as
a refund or a credit against such holder's U.S. federal income tax liability
provided the required information is furnished to the IRS.

     The U.S. Underwriting Agreement and the International Underwriting
Agreement (together, the "Underwriting Agreements") provide that the
obligations of the U.S. Underwriters and the International Managers to purchase
shares of common stock are subject to certain conditions, and that if any of
the foregoing shares of common stock are purchased by the U.S. Underwriters
pursuant to the U.S. Underwriting Agreement or by the International Managers
pursuant to the International Underwriting Agreement, then all the shares of
common stock agreed to be purchased by the U.S.

<PAGE>

Underwriters and the International Managers, as the case may be, pursuant to
their respective underwriting agreements, must be so purchased. The offering
price and underwriting discounts and commissions per share for the U.S.
offering and the international offering are identical. The closing of the U.S.
offering is a condition to the closing of the international offering and the
closing of the international offering is a condition to the closing of the U.S.
offering.

     Holdings and the selling stockholders have been advised by the
Representatives that the U.S. Underwriters and the International Managers
propose to offer the shares of common stock directly to the public at the
public offering price set forth on the cover page of this prospectus, and to
certain selected dealers (who may include the U.S. Underwriters and the
International Managers) at such public offering price less a selling concession
not in excess of $   per share. The selected dealers may reallow a concession
not in excess of $   per share to certain brokers and dealers. After this
offering, the public offering price, the concession to selected dealers and the
reallowance may be changed by the U.S. Underwriters and the International
Managers.

     Holdings and the selling stockholders have agreed to indemnify, under
certain circumstances, the U.S. Underwriters and the International Managers
against certain liabilities, including liabilities under the Securities Act,
and to contribute, under certain circumstances, to payments that the U.S.
Underwriters and the International Managers may be required to make in respect
thereof.

     Holdings has granted to the U.S. Underwriters an option to purchase up to
an aggregate 1,110,000 additional shares of common stock and has granted to the
International Managers an option to purchase up to 277,500 additional shares of
common stock, in each case exercisable solely to cover over-allotments, at the
public offering price less the underwriting discounts and commissions shown on
the cover page of this prospectus. Such options may be exercised at any time
until 30 days after the date of the Underwriting Agreements. To the extent that
the over-allotment option is exercised, each U.S. Underwriter or International
Manager, as the case may be, will be committed, subject to certain conditions,
to purchase a number of additional shares of common stock proportionate to such
U.S. Underwriter's or International Manager's initial commitment as indicated
in the preceding tables.

     The U.S. Underwriters and the International Managers have entered into an
Agreement Between U.S. Underwriters and International Managers pursuant to
which each U.S. Underwriter has agreed that, as part of the distribution of the
shares of common stock offered in the U.S. offering, (i) it is not purchasing
any such shares for the account of anyone other than a U.S. Person (as defined
below), and (ii) it has not offered or sold, will not offer, sell, resell or
deliver, directly or indirectly, any such shares or distribute any prospectus
relating to the U.S. offering to anyone other than a U.S. Person. In addition,
pursuant to such agreement, each International Manager has agreed that, as part
of the distribution of the shares of common stock offered in the international
offering, (i) it is not purchasing any such shares for the account of a U.S.
Person, and (ii) it has not offered or sold, and will not offer, sell, resell
or deliver, directly or indirectly, any of such shares or distribute any
prospectus relating to the international offering to any U.S. Person.

     The foregoing limitations do not apply to stabilization transactions or to
certain other transactions specified in the Underwriting Agreements and the
Agreement Between U.S. Underwriters and International Managers, including (i)

     Pursuant to the Agreement Between the U.S. Underwriters and the
International Managers, sales may be made between the U.S. Underwriters and the
International Managers of such a number of shares of common stock as may be
mutually agreed. The price of any shares so sold shall be the public offering
price as then in effect for the shares of common stock being sold by the U.S.
Underwriters and the International Managers less an amount equal to the selling
concession allocable to such shares of common stock, unless otherwise
determined by mutual agreement. To the extent that there are sales between the
U.S. Underwriters and the International Managers pursuant to the Agreement
Between the U.S. Underwriters and the International Managers the number of
shares of common stock available for sale by the U.S. Underwriters or by the
International Managers may be more or less than the amount specified on the
cover page of the this prospectus.


     Until the distribution of the common stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase shares of common stock. As an exception to
these rules, the Representatives are permitted to engage in certain
transactions that stabilize the price of the common stock. Such transactions
may consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of the common stock.


     If the Underwriters create a short position in the common stock in
connection with this offering (i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus), the Representatives
may reduce that short position by purchasing common stock in the open market.
The Representatives also may elect to reduce any short position by exercising
all or part of the over-allotment options described herein.


     The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that, if the Representatives purchase
shares of common stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the common stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group
members who sold those shares as part of this offering.


     In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
this offering.


     Neither the Company nor any of the Underwriters makes any representation
or prediction as to the direction or magnitude of any effect that the
transactions described above may have on the price of the common stock. In
addition, neither the Company nor any of the Underwriters makes any
representation that the Representatives will engage in such transactions or
that such transactions, once commenced, will not be discontinued without
notice.


     Each International Manager has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the date of issue of
the shares of common stock, will not offer or sell any shares of Common Stock
to persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995, (ii) it has complied and will comply with all
applicable provisions of the Financial Services Act 1986 with respect to
anything done by it in relation to the shares of common stock in, from or
otherwise involving the United Kingdom and (iii) it has only issued or passed
on, and will only issue or pass on to any person in the United Kingdom any
document received by it in connection with the issue of the shares of common
stock if that person is of a kind described in Article 11(3) of the Financial
Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 or is a
person to whom such document may otherwise be issued or passed upon.

exceptions, for a period of     days from the date of this prospectus, directly
or indirectly, offer, sell or otherwise dispose of any shares of common stock

written approval of the customer.

     Lehman Brothers Inc. has provided investment banking, financial advisory
and other services to the Company, for which services Lehman Brothers Inc. has
received customary fees. In addition, certain of the selling stockholders are
affiliates of Lehman Brothers Inc. Furthermore, Lehman Brothers Commercial
Paper Inc., an affiliate of Lehman Brothers Inc., is a lender under the Senior
Credit Facilities. After the completion of this offering and assuming that the
Underwriters' over-allotment option is exercised, the Lehman Partnership will
beneficially own 24.8% of the outstanding capital stock of Holdings and will be
able to significantly influence the business and the affairs of the Company
with respect to matters requiring stockholder approval. See "Management --
Directors and Executive Officers" and "Ownership of Capital Stock".

     Each of Bear, Stearns & Co. Inc., Credit Suisse First Boston Corporation,
Morgan Stanley & Co. Incorporated and C.E. Unterberg, Towbin and certain of
their respective affiliates provided investment banking services to the Company
in connection with the IPO, for which services each received customary fees.

     Under Rule 2720 ("Rule 2720") of the Conduct Rules of the National
Association of Securities Dealers, Inc. ("NASD"), the Company is considered an
affiliate of Lehman Brothers Inc. This offering is being conducted in
accordance with Rule 2720.

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)



1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS


     The accompanying unaudited condensed consolidated (combined) financial
statements include the assets, liabilities and results of operations of L-3
Communications Holdings, Inc. ("Holdings", and together with its subsidiaries,
"L-3" or the "Company"), the successor company, following the change in
ownership effective as of April 1, 1997. Prior to April 1, 1997, the statements
comprise the 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 and (ii) one business unit,
Communication Systems-East, purchased by Lockheed Martin as part of its
acquisition of the aerospace business of GE 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.


     Holdings has no other assets or liabilities and conducts no operations
other than through its wholly-owned subsidiary, L-3 Communications Corporation
("L-3 Communications").


     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.

     Immediately prior to the IPO, each authorized share of Holdings Class A
Common Stock, Class B Common Stock and Class C Common Stock was converted into
one class of common stock, the Common Stock. Each outstanding share of Class A
and Class B Common Stock was converted into one share of Holdings Common Stock.
There was no outstanding Class C Common Stock. The authorized Holdings Common
Stock was increased to 100,000,000 shares.


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 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, net income and diluted earnings per share
for the nine months ended September 30, 1998 and 1997 would have been $834,500,
$17,400 and $0.61 and $758,700, $2,800 and $0.10, 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.

</TABLE>

     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.

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

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 6, 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, and additional consideration based on the
post-acquisition performance of DBS. 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

acquisition was financed with cash on hand and borrowings under the Senior
Credit Facilities.

                        REPORT OF INDEPENDENT AUDITORS


To the Board of Directors of
 L-3 Communications Holdings, Inc.


     We have audited the accompanying (i) consolidated balance sheet of L-3
Communications Holdings, Inc. 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
combined statements of operations and cash flows of the Predecessor Company, as
defined in Note 1 to the Company's financial statements, for the three months
ended March 31, 1997 and (iii) combined balance sheet of the Predecessor
Company as of December 31, 1996 and the related combined statements of
operations, changes in invested equity 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 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.

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 HOLDINGS, INC.

             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 Holdings, Inc.,
("Holdings", and together with its subsidiaries, "L-3", or the "Company"), the
successor company 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.

     Holdings has no other assets or liabilities and conducts no operations
other than through its subsidiary, L-3 Communications Corporation ("L-3
Communications").

     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

     L-3 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 the Company, 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 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

                       L-3 COMMUNICATIONS HOLDINGS, INC.

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

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


                                      F-23
<PAGE>

                       L-3 COMMUNICATIONS HOLDINGS, INC.

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


                                      F-24
<PAGE>

                       L-3 COMMUNICATIONS HOLDINGS, INC.

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
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: In accordance with SFAS No. 128, "Earnings per Share",
basic earnings per share is computed by dividing net income attributable to
common stockholders by the weighted-average number of common shares outstanding
during the period. Diluted earnings per share ("diluted EPS") is computed by
dividing net income attributable to common stockholders adjusted for any other
changes to net income that would result from the assumed issuance of the
dilutive potential common shares by the weighted-average number of common
shares outstanding adjusted to include the number of additional common shares
that would have been outstanding if the dilutive potential common shares had
been issued.

     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


                                      F-25

                       L-3 COMMUNICATIONS HOLDINGS, INC.

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

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
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 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 the Company 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.

     Interest expense of the Predecessor Company was calculated using the
following balances and interest rates:

</TABLE>

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. COMMON STOCK

     The Company's Class A Common Stock possesses full voting rights and Class
B Common Stock and Class C Common Stock possess no voting rights except as
otherwise required by law. However,

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
pursuant to shareholders agreements, the holders of Classes B and C Common
Stock have the right to designate themselves as members of the Board of
Directors as long as they are employees of the Company or any of its
subsidiaries. Each share of Class B Common Stock will convert, at the option of
the Company, into a share of Class A common stock immediately prior to an
initial public offering of equity securities of the Company or upon the
occurrence of certain other events but not later than April, 2006, and will
convert into Class C common stock upon certain other events. Holders of Class B
Common Stock are entitled to share with the holders of Class A Common Stock in
dividends and liquidating distributions.


     The Equity Executives are the holders of the Class B Common Stock which
has a par value of $0.01 per share and have the right until the effective date
of an initial public offering to require the Company to repurchase the Class B
Common Stock under certain circumstances. Accordingly, the Class B Common Stock
has been classified on the consolidated balance sheet as "common stock subject
to repurchase agreement" and excluded from shareholders' equity as of December
31, 1997. At December 31, 1997, 3,000,000 shares of the Class B Common Stock
were authorized and 2,944,000 were outstanding.


     The Company's 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 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:

14. 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:

   Options exercisable, December 31, 1997 .........          --               --
</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.

15. COMMITMENTS AND CONTINGENCIES

     The Company and the Predecessor Company lease certain facilities and
equipment under agreements expiring at various dates through 2011. At December
31, 1997, the Company's future minimum payments for noncancellable operating
leases with initial or remaining terms in excess of one year are as follows:

     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.


16. 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:

   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:

for the Company at December 31, 1997:

   Accrued post-retirement health care and life insurance costs .........    $18,256

</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

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.

19. 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

Martin and its affiliates of $8,846 and $10,924 at December 31, 1997 and 1996,

including treasury, cash management, employee benefits, taxes, risk management,
internal audit, financial reporting, contract administration and general
corporate services. Although certain assets, liabilities and expenses related

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.

                        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.


                                      F-45
<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.

</TABLE>

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

                    SIX MONTHS ENDED JUNE 30, 1998 AND 1997


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

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

     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

                  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.

     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 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.

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:

     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

NOTE H--POSTRETIREMENT BENEFITS (CONTINUED)
 
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.

     The following table provides information on the status of the plan at
December 31, 1997:

</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.

                    SPD TECHNOLOGIES INC. AND SUBSIDIARIES

                  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.


NOTE E--LONG-TERM DEBT

     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.

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.

                  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:

     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.

                           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.

                   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

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.

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.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
ILEX Systems, Inc.:


     We have audited the accompanying consolidated balance sheet of ILEX
Systems, Inc. and subsidiary as of December 31, 1997, and the related
consolidated statements of income, shareholders' equity, and cash flows for the
year then ended. These consolidated financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ILEX
Systems, Inc. and subsidiary as of December 31, 1997, and the results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

                       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.

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>

<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>
<CAPTION>
<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.

(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:

                      $2,401,307
                      ==========
</TABLE>

     Rent expense, exclusive of sublease rentals, was approximately $1,081,636
in 1997. Sublease rental income was approximately $186,733 in 1997.


(8) SIGNIFICANT CUSTOMERS


     For the year ended December 31, 1997, sales to a single customer
represented 26% of revenues. The outstanding accounts receivable and unbilled
receivable balances for this customer as of December 31, 1997, were $1,257,875
and $2,228,650, respectively.


(9) SUBSEQUENT EVENT


     In January 1998, shareholders of the Company agreed to sell all of their
common stock for approximately $50,000,000, subject to certain adjustments,
plus additional consideration based on post-acquisition performance. The sale
closed on February 27, 1998.

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.


CONTRACTS IN PROCESS

     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.

                             (DOLLARS IN THOUSANDS)
 
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.


     The net postretirement benefit costs for 1997 included the following

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>
<CAPTION>
<S>                                   <C>
  Equity ..........................   $5,751
  Interest Rate ...................    9.6%
</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.

</TABLE>

     For the year ended December 31, 1997, there were no general and
administrative, independent research and development, or bid and proposal costs
charged to inventory.


     Contracts in process, amounting to $793 as of December 31, 1997, include
accumulated inventoried costs and profits on cost or cost-reimbursement
contracts, principally with the U.S. Government. The U.S. Government has title
to, or a security interest in, inventories to which progress payments are
applied. The Company believes that substantially all such amounts will be
billed and collected within one year.

6. INCOME TAXES


     The effective tax rate differs from the statutory federal income tax rate
for the following reasons:



<TABLE>
<S>                                                          <C>

           State taxes net of federal benefit ............     (6.0)%
           Foreign losses with no tax benefit ............      6.7 %
           Foreign sales corporation tax benefit .........     (4.5)%
           Other, net ....................................     (0.5)%
                                                             ------
                                                              (39.3)%
                                                             ======
</TABLE>

     At December 31, 1997, the German trade tax and corporate income tax net
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:

</TABLE>

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.

     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.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law (the "DGCL") provides
for, among other things:

     (i) 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;

     (ii) 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;

     (iii) 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 (i) and (ii)
   above; and

     (iv) 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") provides that the Registrant shall, to the fullest extent
permitted by the DGCL, (i) indemnify its officers and directors and (ii)
advance expenses incurred by such officers or directors in relation to any
action, suit or proceeding.

     The Registrant's Bylaws (the "Bylaws") require 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 Bylaws
provide that indemnification shall include not only reasonable expenses, but
also judgments, fines, penalties and amounts paid in settlement. The Bylaws
provide that the Registrant 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.


                                      II-1
<PAGE>

     The Bylaws purport to confer upon officers and directors contractual
rights to indemnification and advancement of expenses as provided therein.


     The Certificate of Incorporation limits the personal liability of
directors to the Registrant or its stockholders for monetary damages for breach
of the fiduciary 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 15. RECENT SALES OF UNREGISTERED SECURITIES.


     On April 30, 1997, L-3 Communications issued 100 shares of its common
stock to Holdings for aggregate consideration of $125 million. The securities
were sold directly by L-3 Communications and did not involve any underwriter.
L-3 Communications considers these securities to have been offered and sold in
a transaction not involving any public offering and, therefore, to be exempted
from registration under Section 4(2) of the Securities Act.


     On December 11, 1998, L-3 Communications Corporation issued $200.0 million
in aggregate principal amount of its 8% Senior Subordinated Notes due August 1,
2008. The securities were sold to Lehman Brothers Inc. and NationsBanc
Montgomery Securities LLC. L-3 Communications considers these securities to be
exempted from registration under the Securities Act.

ITEM 17. UNDERTAKINGS.


     (a) 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, 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.


     (b) The undersigned Registrant hereby undertakes that:


     (1) For purposes of determining any liability under the Securities Act of
   1933, the information omitted from the form of prospectus filed as part of
   this Registration Statement in reliance upon Rule 430A and contained in a
   form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
   (4) or 497(h) under the Securities Act shall be deemed to be part of this
   Registration Statement as of the time it was declared effective.


     (2) For the purpose of determining any liability under the Securities Act
   of 1933, each post-effective amendment that contains a form of prospectus
   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.

462(b) under the Securities Act of 1933, as amended, and any and all amendments
(including post-effective amendments) and exhibits thereto, and any and all
applications and other documents relating thereto, with the Securities and
Exchange Commission, with full power and authority to perform and do any and
all acts and things whatsoever which any such attorney or substitute may deem

benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal, premium or Liquidated Damages, if any, or interest on the

such payment. While any such default continues, the Trustee may require a

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.

Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05. HOLDER LISTS.

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).

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 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,

restrictions on transfer comparable to those set forth herein to the extent
required by the Securities Act. 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.

         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Restricted
         Period transfers of beneficial interests in the Regulation S Global
         Note may not be made to a U.S. Person or for the account or benefit of
         a U.S. Person (other than an Initial Purchaser). 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

         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 


<PAGE>
                                                                             34


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.

                  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 


<PAGE>
                                                                             35


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.

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 Indenture

<PAGE>
                                                                             36


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;

                  (d)      the name and address of the Paying Agent;


<PAGE>
                                                                             37


                  (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.

SECTION 3.06. NOTES REDEEMED IN PART.

                  Upon surrender of a Note that is redeemed in part, the
Company shall issue and, upon the Company's written request, the Trustee shall
authenticate for the Holder at the expense of the 

<PAGE>
                                                                             38


Company a new Note equal in principal amount to the unredeemed portion of the 
Note surrendered.

SECTION 3.07. OPTIONAL REDEMPTION.

                  (a) Except as set forth in clause (b) of this Section 3.7,
the Notes shall not be redeemable at the Company's option prior to December 1,
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 and
Liquidated Damages thereon, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on December 1 of the years
indicated below:

 YEAR.......................................................PERCENTAGE
 2003.........................................................104.000%
 2004.........................................................102.667%
 2005.........................................................101.333%
 2006 and thereafter..........................................100.000%

                  (b) Notwithstanding the foregoing clause (a), 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 Notes originally issued at a
redemption price of 108.000% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages thereon, 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 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.

SECTION 3.08. MANDATORY REDEMPTION.

                  Except as set forth under Sections 4.10 and 4.15, the Company
is not required to make mandatory redemption or sinking fund payments with
respect to the Notes.

SECTION 3.09. OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

                  In the event that, pursuant to Section 4.10 hereof, the
Company shall be required to commence an offer to all Holders to purchase Notes
(an "Asset Sale Offer"), it shall follow the procedures specified below.

                  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.


<PAGE>
                                                                             39


                  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 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).


<PAGE>
                                                                             40


                  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.

                                   COVENANTS

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

                  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 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 and Liquidated Damages (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 


<PAGE>
                                                                             41

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

event required to be therein reported, such other reports on Form 8-K (or any

                  (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

of any information contained therein or determinable from 


<PAGE>

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.

                  (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

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 4.07. 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 $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

                                                                             44


         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 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 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 


<PAGE>
                                                                             45


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) 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, the 1997 Indenture, the 1997
Notes, the May 1998 Notes Indenture and the May 1998 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 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,

                                                                             46


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
         $200.0 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 


<PAGE>
                                                                             47


         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);

                  (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;


<PAGE>
                                                                             48


                  (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;

                  (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 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 (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 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 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.

                                                                             51


                  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 date of the Indenture, then such Subsidiary shall execute
a Subsidiary Guarantee, in the form of the Supplemental Indenture attached
hereto as Exhibit E, and the Form of Notation on Senior Subordinated Note,
attached hereto as Exhibit F, 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.

                  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

                                                                             52


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.

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 and Liquidated Damages thereon, if any, 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 


<PAGE>
                                                                             53


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 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 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.

                  (a) the Company defaults in the payment when due of interest
on, or Liquidated Damages, if any, with respect to, the Notes and such default
continues for a period of 30 days (whether or not prohibited by the
subordination provisions of this Indenture);

                  (e) a default occurs 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 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

                                                                             56

                                    (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;

                  Significant Subsidiary or for all or substantially all of the
                  property of the Company or any of its Significant
                  Subsidiaries or any group of Subsidiaries that, taken as a
                  whole, would constitute a Significant Subsidiary; or

                                    (iii) orders the liquidation of the Company
                  or any of its Significant Subsidiaries or any group of
                  Subsidiaries that, taken as a whole, would constitute a
                  Significant Subsidiary;

                  and the order or decree remains unstayed and in effect for 60
                  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

<PAGE>
                                                                             57


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 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 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 Notes prior to August 1, 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 December 1 of the years indicated below:

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

                                                                             58


                                                                        
Default or Event of Default in the payment of the principal of, premium and
Liquidated Damages, if any, 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.

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
Liquidated Damages, if any, 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

                                                                             59


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 Liquidated Damages, if any, and interest
remaining unpaid 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

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.

own affairs.

                  (b) Except during the continuance of an Event of Default:

                                    (i) the duties of the Trustee shall be

                  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).

                                    (i) this paragraph does not limit the
                  effect of paragraph (b) of this Section;

                  any error of judgment made in good faith by a Responsible

                  in ascertaining the pertinent facts; and

                                    (iii) the Trustee shall not be liable with

                  Section 6.05 hereof.

                  (d) Whether or not therein expressly so provided, every

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.

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

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

dated as of such reporting date that complies with TIA ss. 313(a) (but if no

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.

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
counsel. The Company need not pay for any settlement made without its consent,

survive the satisfaction and discharge of this Indenture.

Event of Default specified in Section 6.01(g) or (h) hereof occurs, the

313(b)(2) to the extent applicable.

                                    (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

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.

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

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 

<PAGE>
                                                                             66


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, 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 and Liquidated Damages, 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;

                  (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 

<PAGE>
                                                                             68



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.

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.

                                                                             69


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.

                                   ARTICLE 9.
                        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;

                  (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 

<PAGE>
                                                                             70



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 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;
<PAGE>
                                                                             71


                  (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.

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.
<PAGE>
                                                                             72


                  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.

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

<PAGE>
                                                                             73



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:

                                    (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 

<PAGE>
                                                                             74



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 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:

                                                                             75


                                    (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.

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.

                                 MISCELLANEOUS

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
control.

Section 11.02. Notices.

                  Any notice or communication by the Company or the Trustee to
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
shall mail a copy to the Trustee and each Agent at the same time.

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

satisfactory to the Trustee (which shall include the statements set forth in

conditions precedent and covenants, if any, provided for in this Indenture
relating to the proposed action have been satisfied; and

                                                                             78


                  (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
opinion has read such covenant or condition;

                  (b) a brief statement as to the nature and scope of the

she has made such examination or investigation as is necessary to enable him to

Person, such condition or covenant has been satisfied.

Section 11.06. Rule by Trustee and Agents.

                  The Trustee may make reasonable rules for action by or at a
meeting of Holders. The Registrar or Paying Agent may make reasonable rules and
set reasonable requirements for its functions.

Section 11.07. 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 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.

USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES,
WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

Section 11.09. No Adverse Interpretation of other Agreements.

                  This Indenture may not be used to interpret any other
indenture, loan or debt agreement of the Company or its Subsidiaries or of any
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

                  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%
per annum from December 11, 1998 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Company will pay interest and Liquidated Damages, if
any, semi-annually on February 1 and August 1 of each year, 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 February 1, 1999. 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) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the January 15 or July 15 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 and
Liquidated Damages, 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 and Liquidated Damages 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 and
Liquidated Damages 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.


                                      A-3
<PAGE>

     4. INDENTURE. The Company issued the Notes under an Indenture dated as of
December 11, 1998 ("Indenture") among the Company, the Guarantors named therein
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 $300.0 million in aggregate principal
amount, plus amounts, if any, issued to pay Liquidated Damages on outstanding
Notes as set forth in Paragraph 2 hereof.

     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 August 1,
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 and
Liquidated Damages thereon, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on August 1 of the years
indicated below:

        YEAR                                        PERCENTAGE
        2003....................................    104.000%
        2004....................................    102.667%
        2005....................................    101.333%
        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% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages thereon, 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 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.



                                      A-4
<PAGE>

     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 (an "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 (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 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.

                                      A-5
<PAGE>

     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.

     12. DEFAULTS AND REMEDIES. An "Event of Default" occurs if: (i) default
for 30 days in the payment when due of interest on, or Liquidated Damages with
respect to, 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 


                                      A-6
<PAGE>

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
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 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 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 


                                      A-7
<PAGE>

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. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES. In
addition to the rights provided to Holders of Notes under the Indenture,
Holders of Transferred Restricted Securities shall have all the rights set
forth in the A/B Exchange Registration Rights Agreement dated as of December
11, 1998, between the Company and the parties named on the signature pages
thereof (the "Registration Rights Agreement").

     18. 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.

     19. 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 and/or the Registration Rights Agreement.
Requests may be made to:

                  (i)  the principal of, premium and interest on
                       the Notes will be promptly paid in full
                       when due, whether at maturity, by
                       acceleration, redemption or otherwise, and
                       interest on the overdue principal of,

                       thereunder or under the Indenture will be
                       promptly paid in full, all in accordance
                       with the terms thereof; and

                  similar law.

3. EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEES.

         (a)      To evidence its Subsidiary Guarantee set forth in this
                  Supplemental Indenture, the Guaranteeing Subsidiary hereby
                  agrees that a notation of such Subsidiary Guarantee
                  substantially in the form of Exhibit F to the Indenture shall
                  be endorsed by an officer of such Guaranteeing Subsidiary on
                  each 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 endorse on each Note a notation of such Subsidiary
                  Guarantee.

         (c)      If an Officer whose signature is on this Supplemental
                  Indenture or on the Subsidiary Guarantee no longer holds that
                  office at the time the Trustee authenticates the Note on
                  which a Subsidiary Guarantee is endorsed, the Subsidiary
                  Guarantee shall be valid nevertheless.

         (d)      The delivery of any Note by the Trustee, after the
                  authentication thereof under the Indenture, shall constitute
                  due delivery of the Subsidiary Guarantee set forth in this
                  Supplemental Indenture on behalf of the Guaranteeing
                  Subsidiary.

         (e)      The Guaranteeing Subsidiary hereby agrees that its
                  obligations hereunder shall be unconditional, regardless of
                  the validity, regularity or enforceability of the Notes or
                  the Indenture, the absence of any action to enforce the same,
                  any waiver or consent by any Holder of the Notes with respect
                  to any provisions of the Notes or the Indenture, the recovery
                  of any judgment against the Company, any action to enforce
                  the same or any other circumstance which might otherwise
                  constitute a legal or equitable discharge or defense of a
                  guarantor.

         (f)      The Guaranteeing Subsidiary hereby waives diligence,
                  presentment, demand of payment, filing of claims with a court
                  in the event of insolvency or bankruptcy of the Company, any
                  right to require a proceeding first against the Company,
                  protest, notice and all demands whatsoever and covenants that
                  its Subsidiary Guarantee made pursuant to this 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, liquidator or other
                  similar official acting in relation to either the Company or
                  the Guaranteeing 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
                  Guaranteeing Subsidiary, on the one hand, and the Holders and
                  the Trustee, on the other hand:

                  (i)    the maturity of the obligations guaranteed
                         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

                                      E-3

                  (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
                        the purpose of the Subsidiary Guarantee
                        made pursuant to this Supplemental
                        Indenture.

           (i)    The Guaranteeing Subsidiary shall have the right to 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 pursuant to this Supplemental
                  Indenture.

        4. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

                            in the Notes shall prevent any
                            consolidation or merger of the Guaranteeing
                            Subsidiary with or into the Company or any
                            other Guaranteeing Subsidiary or shall
                            prevent any transfer, sale or conveyance of
                            the property of the Guaranteeing Subsidiary
                            as an entirety or substantially as an
                            entirety, to the Company or any other

                            other Guaranteeing Subsidiary (in each
                            case, whether or not affiliated with the
                            Guaranteeing Subsidiary), or successive

                            expressly 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

                           corporation which shall have acquired such
                           property and (ii) immediately after giving
                           effect to such consolidation, merger, sale

                           in form to the Trustee, of the Subsidiary
                           Guarantee made pursuant to this
                           Supplemental Indenture and the due and
                           punctual performance of all of the
                           covenants and conditions of the Indenture
                           and this Supplemental Indenture to be
                           performed by the Guaranteeing Subsidiary,
                           such successor corporation shall succeed to
                           and be substituted for the 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

                           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.

                           its obligations under its
                           Subsidiary Guarantee. Any
                           Guaranteeing Subsidiary not
                           released from its obligations

                           Guaranteeing Subsidiary under the
                           Indenture as provided in Article 10.

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 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.

                          EXHIBIT F

FORM OF NOTATION ON SENIOR SUBORDINATED NOTE RELATING TO SUBSIDIARY GUARANTEE

                  Pursuant to the Indenture (the "Indenture") dated as of
December 11, 1998 among L-3 Communications Corporation, the Guarantors named
therein and The Bank of New York, as trustee (the "Trustee"), each Guarantor
(i) has jointly and severally unconditionally guaranteed (a) the due and
punctual payment of the principal of, and premium, interest and Liquidated
Damages 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 and
Liquidated Damages 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 Guarantor would constitute or result in a violation
of any applicable fraudulent conveyance or similar law of any relevant
jurisdiction, the liability of such Guarantor 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 Guarantor, as such, shall have
any liability for any obligations of the Company or any Guarantor under the
Notes, any Subsidiary Guarantee, the Indenture, any supplemental indenture
delivered pursuant to the Indenture by such Guarantor 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
Guarantor 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.

         3.1 Unless the Exchange Offer shall not be permissible under
applicable law or Commission policy (after the procedures set forth in Section
6(a) below have been complied with), the Company and the Guarantors shall (i)
cause to be filed with the Commission as soon as practicable after the Closing
Date, but in no event later than 90 days after the Closing Date, a Registration
Statement under the Act relating to the Series B Notes (including the
Subsidiary Guarantees) and the Exchange Offer, (ii) use all commercially
reasonable efforts to cause such Registration Statement to become effective at
the earliest possible time, but in no event later than 150 days after the
Closing Date (which 150-day period shall be extended for a number of days equal
to the number of business days, if any, the Commission is officially closed
during such period), (iii) in connection with the foregoing, file (A) all
pre-effective amendments to such Registration Statement as may be necessary in
order to cause such Registration Statement to become effective, (B) if
applicable, a post-effective amendment to such Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings in connection
with the registration and qualification of the Series B Notes (including the
Subsidiary Guarantees) to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer,
and (iv) upon the effectiveness of such Registration Statement, commence the
Exchange Offer. The Exchange Offer shall be on the appropriate form permitting
registration of the Series B Notes (including the Subsidiary Guarantees) to be
offered in exchange for the Transfer Restricted Securities and to permit
resales of Notes held by Broker-Dealers as contemplated by Section 3(c) below.

         3.2 The Company and the Guarantors shall cause the Exchange Offer

applicable federal and state securities laws to

                                      -4-
                                                                    

<PAGE>





Consummate the Exchange Offer; provided, however, that in no event shall such
period be less than 20 business days. The Company and the Guarantors shall
cause the Exchange Offer to comply with all applicable federal and state
securities laws. No securities other than the Notes (including the Subsidiary
Guaranteess) shall be included in the Exchange Offer Registration Statement.
The Company and the Guarantors shall use their best efforts to cause the
Exchange Offer to be Consummated on the earliest practicable date after the
Exchange Offer Registration Statement has become effective, but in no event
later than 30 business days thereafter.

         3.3 The Company and the Guarantors shall indicate in a "Plan of
Distribution" section contained in the Prospectus contained in the Exchange
Offer Registration Statement that any Broker-Dealer who holds Series A Notes
that are Transfer Restricted Securities and that were acquired for its own
account as a result of market-making activities or other trading activities
(other than Transfer Restricted Securities acquired directly from the Company),
may exchange such Series A Notes pursuant to the Exchange Offer; however, such
Broker-Dealer may be deemed to be an "underwriter" within the meaning of the
Act and must, therefore, deliver a Prospectus meeting the requirements of the
Act in connection with any resales of the Series B Notes received by such
Broker-Dealer in the Exchange Offer, which Prospectus delivery requirement may
be satisfied by the delivery by such Broker-Dealer of the Prospectus contained
in the Exchange Offer Registration Statement. Such "Plan of Distribution"
section shall also contain all other information with respect to such resales
by Broker-Dealers that the Commission may require in order to permit such
resales pursuant thereto, but such "Plan of Distribution" shall not name any
such Broker-Dealer or disclose the amount of Notes held by any such
Broker-Dealer except to the extent required by the Commission.

         The Company and the Guarantors shall use all commercially reasonable
efforts to keep the Exchange Offer Registration Statement continuously
effective, supplemented and amended as required by the provisions of Section
6(d) below to the extent necessary to ensure that it is available for resales
of Notes acquired by Broker-Dealers for their own accounts as a result of
market-making activities or other trading activities, and to ensure that it
conforms with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of 180 days from the date on which the Exchange Offer Registration
Statement is declared effective.

         The Company and the Guarantors shall provide sufficient copies of the
latest version of such Prospectus to Broker-Dealers promptly upon request at
any time during such 180 day period in order to facilitate such resales.

                  SECTION 4. SHELF REGISTRATION; MARKET-MAKER
                                   PROSPECTUS

         4.1 Shelf Registration. If (i) the Company and the Guarantors are not
required to file an Exchange Offer Registration Statement or to Consummate the
Exchange Offer because the Exchange Offer is not permitted by applicable law or
Commission policy (after the procedures set forth in Section 6(a) below have
been complied with) or (ii) if any Holder of Transfer Restricted Securities
that is a "qualified institutional buyer," as such term is defined in Rule 144A
under the Act or an institutional "accredited investor," as such term is
defined in Rule 501(a)(1), (2), (3) and

                                      -5-
                                                                    

<PAGE>



(7) under the Act shall notify the Company prior to the 20th business day
following the Consummation of the Exchange Offer that such Holder alone or
together with holders who hold in the aggregate at least $1.0 million in
principal amount of Series A Notes (A) is prohibited by applicable law or
Commission policy from participating in the Exchange Offer, or (B) may not
resell the Series B Notes acquired by it in the Exchange Offer to the public
without delivering a prospectus and that the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder, or (C) is a Broker-Dealer and holds Series A Notes
acquired directly from the Company or one of its affiliates, then the Company
and the Guarantors shall

          (x) cause to be filed a shelf Registration Statement pursuant to Rule
     415 under the Act, which may be an amendment to the Exchange Offer
     Registration Statement (in either event, the "Shelf Registration
     Statement") on or prior to the earliest to occur of (1) the 30th day after
     the date on which the Company determines that it is not required to file
     the Exchange Offer Registration Statement, or permitted to Consummate the
     Exchange Offer and (2) the 30th day after the date on which the Company
     receives notice from a Holder of Transfer Restricted Securities as
     contemplated by clause (ii) of paragraph (a) above (such earliest date
     being the "Shelf Filing Deadline"), which Shelf Registration Statement
     shall provide for resales of all Transfer Restricted Securities the
     Holders of which shall have provided the information required pursuant to
     Section 4(b) hereof; and

          (y) use all commercially reasonable efforts to cause such Shelf
     Registration Statement to be declared effective by the Commission on or
     before the 90th day after the Shelf Filing Deadline.

The Company and the Guarantors shall use all commercially reasonable efforts to
keep such Shelf Registration Statement continuously effective, supplemented and
amended as required by the provisions of Sections 6(b) and (d) hereof to the
extent necessary to ensure that it is available for resales of Notes by the
Holders of Transfer Restricted Securities entitled to the benefit of this
Section 4(a), and to ensure that it conforms with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years following the
Closing Date or such shorter period that will terminate when all Notes covered
by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or become eligible for resale pursuant to Rule 144
without volume or other restrictions.

         4.2 Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 10 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. No Holder of Transfer Restricted Securities shall
be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until
such Holder shall have used its best efforts to provide all such reasonably
requested information. Each Holder as to which any Shelf Registration Statement
is being effected agrees to furnish promptly to the Company all information
required to be disclosed in order to make the information previously furnished
to the Company by such Holder not materially misleading.

         4.3 Market-Maker Prospectus. The Company and the Guarantors
acknowledge that any Restricted Broker-Dealer holding Broker-Dealer Transfer
Restricted Securities may not

                                      -6-
                                                                    

<PAGE>





resell such Broker-Dealer Transfer Restricted Securities without delivering a
Prospectus. Consequently, on the date that the Exchange Offer Registration
Statement is filed with the Commission, the Company and the Guarantors shall
file a Registration Statement (which may be the Exchange Offer Registration
Statement or the Shelf Registration Statement if permitted by the rules and
regulations of the Commission) and shall use their best efforts to cause such
Registration Statement to be declared effective by the Commission on or prior
to the Consummation of the Exchange Offer. The Company and the Guarantors shall
use all commercially reasonable efforts to keep such Registration Statement
continuously effective, supplemented and amended as required by the provisions
of Sections 6(c) and (d) hereof to the extent necessary to ensure that it is
available for resales of Broker-Dealer Transfer Restricted Securities by
Restricted Broker-Dealers, and to ensure that it conforms with the requirements
of this Agreement, the Act and the policies, rules and regulations of the
Commission as announced from time to time, until such time as all Restricted
Broker-Dealers determine in their judgment that they are no longer required to
deliver a Prospectus in connection with sales of Broker-Dealer Transfer
Restricted Securities. The Prospectus included in such Registration Statement
is referred to in this Agreement as a "Market-Maker Prospectus."

         SECTION 5. LIQUIDATED DAMAGES

         If (i) any of the Registration Statements required by this Agreement
is not filed with the Commission on or prior to the date specified for such
filing in sections 3(a), 4(a), and 4(c), as applicable, (ii) any of such
required Registration Statements has not been declared effective by the
Commission on or prior to the date specified for such effectiveness in sections
3(a), 4(a), and 4(c), as applicable, (the "Effectiveness Target Date"), (iii)
the Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) any Registration Statement required by this Agreement is
filed and declared effective but shall thereafter cease to be effective or fail
to be usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself immediately declared effective (each such event referred to
in clauses (i) through (iv), a "Registration Default"), the Company and the
Guarantors jointly and severally agree to pay liquidated damages to each Holder
of Transfer Restricted Securities with respect to the first 90-day period
immediately following the occurrence of such Registration Default, in an amount
equal to $.05 per week per $1,000 principal amount of Transfer Restricted
Securities held by such Holder for each week or portion thereof that the
Registration Default continues. The amount of the liquidated damages shall
increase by an additional $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities 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 Transfer
Restricted Securities. All accrued liquidated damages shall be paid to Record
Holders by the Company and the Guarantors by wire transfer of immediately
available funds or by federal funds check on each Damages Payment Date, as
provided in the Indenture. Following the cure of all Registration Defaults
relating to any particular Transfer Restricted Securities, the accrual of
liquidated damages with respect to such Transfer Restricted Securities will
cease.

         All payment obligations of the Company and the Guarantors set forth in
the preceding paragraph that are outstanding with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer
Restricted Security shall survive until such time as all such payment

                                      -7-
                                                                    

<PAGE>



obligations with respect to such Security shall have been satisfied in full.

         SECTION 6. REGISTRATION PROCEDURES

         6.1 Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company and the Guarantors shall comply with all of the
provisions of Section 6(d) below, shall use all commercially reasonable efforts
to effect such exchange to permit the sale of Transfer Restricted Securities
being sold in accordance with the intended method or methods of distribution
thereof, and shall comply with all of the following provisions:

          (a) If in the reasonable opinion of counsel to the Company and the
     Guarantors there is a question as to whether the Exchange Offer is
     permitted by applicable law, the Company and the Guarantors hereby agree
     to seek a no-action letter or other favorable decision from the Commission
     allowing the Company and the Guarantors to Consummate an Exchange Offer
     for such Series A Notes. The Company and the Guarantors hereby agree to
     pursue the issuance of such a decision to the Commission staff level but
     shall not be required to take commercially unreasonable action to effect a
     change of Commission policy. The Company and the Guarantors hereby agree
     however, to (A) participate in telephonic conferences with the Commission,
     (B) deliver to the Commission staff an analysis prepared by counsel to the
     Company and the Guarantors setting forth the legal bases, if any, upon
     which such counsel has concluded that such an Exchange Offer should be
     permitted and (C) diligently pursue a resolution (which need not be
     favorable) by the Commission staff of such submission.

          (b) As a condition to its participation in the Exchange Offer
     pursuant to the terms of this Agreement, each Holder of Transfer
     Restricted Securities shall furnish, upon the request of the Company,
     prior to the Consummation thereof, a written representation to the Company
     and the Guarantors (which may be contained in the letter of transmittal
     contemplated by the Exchange Offer Registration Statement) to the effect
     that (A) it is not an affiliate of the Company, (B) it is not engaged in,
     and does not intend to engage in, and has no arrangement or understanding
     with any person to participate in, a distribution of the Series B Notes to
     be issued in the Exchange Offer and (C) it is acquiring the Series B Notes
     in its ordinary course of business. In addition, all such Holders of
     Transfer Restricted Securities shall otherwise cooperate in the Company's
     and the Guarantors' preparations for the Exchange Offer. Each Holder
     hereby acknowledges and agrees that any Broker-Dealer and any such Holder
     using the Exchange Offer to participate in a distribution of the
     securities to be acquired in the Exchange Offer (1) could not under
     Commission policy as in effect on the date of this Agreement rely on the
     position of the Commission enunciated in Morgan Stanley and Co., Inc.
     (available June 5, 1991) and Exxon Capital Holdings Corporation (available
     May 13, 1988), as interpreted in the Commission's letter to Shearman &
     Sterling dated July 2, 1993, and similar no-action letters (including any
     no-action letter obtained pursuant to clause (i) above), and (2) must
     comply with the registration and prospectus delivery requirements of the
     Act in connection with a secondary resale transaction and that such a
     secondary resale transaction should be covered by an effective
     Registration Statement containing the selling security holder information
     required by Item 507 or 508, as applicable, of Regulation S-K if the
     resales are of Series B Notes obtained by such Holder in exchange for
     Series A Notes acquired by such Holder directly from the Company.

                                      -8-
                                                                    

<PAGE>





          (c) Prior to effectiveness of the Exchange Offer Registration
     Statement, the Company and the Guarantors shall provide a supplemental
     letter to the Commission (A) stating that the Company and the Guarantors
     are registering the Exchange Offer in reliance on the position of the
     Commission enunciated in Exxon Capital Holdings Corporation (available May
     13, 1988), Morgan Stanley and Co., Inc. (available June 5, 1991) and, if
     applicable, any no-action letter obtained pursuant to clause (i) above and
     (B) including a representation that neither the Company nor any Guarantor
     has entered into any arrangement or understanding with any Person to
     distribute the Series B Notes to be received in the Exchange Offer and
     that, to the best of the Company's and each Guarantor's information and
     belief, each Holder participating in the Exchange Offer is acquiring the
     Series B Notes in its ordinary course of business and has no arrangement
     or understanding with any Person to participate in the distribution of the
     Series B Notes received in the Exchange Offer.

         6.2 (a) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company and the Guarantors shall comply with all
the provisions of Section 6(d) below and shall use all commercially reasonable
efforts to effect such registration to permit the sale of the Transfer
Restricted Securities being sold in accordance with the intended method or
methods of distribution thereof, and pursuant thereto the Company and the
Guarantors will as expeditiously as possible prepare and file with the
Commission a Registration Statement relating to the registration on any
appropriate form under the Act, which form shall be available for the sale of
the Transfer Restricted Securities in accordance with the intended method or
methods of distribution thereof.

Statement filed pursuant to Section 4(c) of this Agreement, the Company and the
Guarantors will comply with all of the provisions of Section 6(d) below (other

Restricted Broker-Dealers determine in their judgment that they are no longer
required to deliver Market-Maker Prospectuses in connection with sales of

shall use all commercially reasonable efforts to deliver Market-Maker
Prospectuses to all Restricted Broker-Dealers immediately upon the
effectiveness of the Registration Statement and from time to time thereafter
upon request, in such quantities as such Restricted Broker-Dealer shall
require.

         6.4 General Provisions. In connection with any Registration Statement
and any Prospectus required by this Agreement to permit the sale or resale of

Broker-Dealers) and Broker-Dealer Transfer Restricted Securities, the Company
and the Guarantors shall:

          (a) use all commercially reasonable efforts to keep such Registration
     Statement continuously effective and provide all requisite financial
     statements (including, if required by the Act or any regulation
     thereunder, financial statements of any Guarantors) for the period
     specified in Section 3 or 4 of this Agreement, as applicable; upon the
     occurrence of any event that would cause any such Registration Statement
     or the Prospectus contained therein (A) to contain a material misstatement
     or omission or (B) not to be effective and usable for resale of Transfer
     Restricted Securities or Broker-Dealer Transfer

                                      -9-

Restricted Securities during the period required by this Agreement, the Company
and the Guarantors shall file promptly an appropriate amendment to such
Registration Statement, in the case of clause (A), correcting any such
misstatement or omission, and, in the case of either clause (A) or (B), use all
commercially reasonable efforts to cause such amendment to be declared
effective and such Registration Statement and the related Prospectus to become
usable for their intended purpose(s) as soon as practicable thereafter.
Notwithstanding the foregoing, at any time after Consummation of the Exchange
Offer, the Company and the Guarantors may allow the Shelf Registration
Statement or Market-Maker Prospectus and the related Registration Statement to
cease to become effective and usable if (x) the board of directors of the
Company determines in good faith that it is in the best interests of the
Company not to disclose the existence of or facts surrounding any proposed or
pending material corporate transaction involving the Company and the
Guarantors, and the Company notifies the Holders within two business days after
the Board of Directors makes such determination, or (y) the Prospectus
contained in the Shelf Registration Statement or the Market-Maker Prospectus,
as the case may be, contains an untrue statement of the material fact or omits
to state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading; provided
that the two-year period referred to in Section 4(a) hereof during which the
Shelf Registration Statement is required to be effective and usable shall be
extended by the number of days during which such Registration Statement was not
effective or usable pursuant to the foregoing provisions;

          (b) prepare and file with the Commission such amendments and
     post-effective amendments to the Registration Statement as may be
     necessary to keep the Registration Statement effective for the applicable
     period set forth in Section 3 or 4 hereof, as applicable; cause the
     Prospectus to be supplemented by any required Prospectus supplement, and
     as so supplemented to be filed pursuant to Rule 424 under the Act, and to
     comply fully with the applicable provisions of Rules 424 and 430A under
     the Act in a timely manner; and comply with the provisions of the Act with
     respect to the disposition of all securities covered by such Registration
     Statement during the applicable period in accordance with the intended
     method or methods of distribution by the sellers thereof set forth in such
     Registration Statement or supplement to the Prospectus;

          (c) advise the underwriter(s), if any, and selling Holders of
     Transfer Restricted Securities and, following the Consummation of the
     Exchange Offer, Holders of Broker Dealer Transfer Restricted Securities,
     promptly and, if requested by such Persons, to confirm such advice in
     writing, (A) when the Prospectus or any Prospectus supplement or
     post-effective amendment has been filed, and, with respect to any
     Registration Statement or any post-effective amendment thereto, when the
     same has become effective, (B) of any request by the Commission for
     amendments to the Registration Statement or amendments or supplements to
     the Prospectus or for additional information relating thereto, (C) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement under the Act or of the suspension by any
     state securities commission of the qualification of the Transfer
     Restricted Securities or Broker-Dealer Transfer Restricted Securities, as
     applicable, for offering or sale in any jurisdiction, or the initiation of
     any proceeding for any of the preceding purposes, (D) of the existence of
     any fact or the happening of any event that makes any statement of a
     material fact made in the Registration Statement, the Prospectus, any
     amendment or supplement thereto, or any document

                                      -10-

     incorporated by reference therein untrue, or that requires the making of
     any additions to or changes in the Registration Statement or the
     Prospectus in order to make the statements therein not misleading. If at
     any time the Commission shall issue any stop order suspending the
     effectiveness of the Registration Statement, or any state securities
     commission or other regulatory authority shall issue an order suspending
     the qualification or exemption from qualification of the Transfer
     Restricted Securities or Broker-Dealer Transfer Restricted Securities, as
     applicable, under state securities or Blue Sky laws, the Company and the
     Guarantors shall use all commercially reasonable efforts to obtain the
     withdrawal or lifting of such order at the earliest possible time;

          (d) furnish to each of the selling Holders of Transfer Restricted

     initial filing of such Registration Statement), which documents will be
     subject to the review of such Holders and underwriter(s), if any, for a
     period of at least five business days, and the Company and the Guarantors
     will not file any such Registration Statement or Prospectus or any
     amendment or supplement to any such Registration Statement or Prospectus
     (including all such documents incorporated by reference) if a selling
     Holder of Transfer Restricted Securities or a Holder of Broker-Dealer
     Transfer Restricted Securities, as applicable, covered by such
     Registration Statement or the underwriter(s), if any, shall not have had
     an opportunity to participate in the preparation thereof;

          (e) promptly prior to the filing of any document that is to be
     incorporated by reference into a Registration Statement or Prospectus,
     provide copies of such document to the selling Holders or the Holders of
     Broker-Dealer Transfer Restricted Securities, as applicable, and to the
     underwriter(s), if any, make the Company's and the Guarantors'
     representatives available for discussion of such document and other
     customary due diligence matters, and include such information in such
     document prior to the filing thereof as such selling Holders or the
     Holders of Broker-Dealer Transfer Restricted Securities, as applicable, or
     underwriter(s), if any, reasonably may request;

          (f) make available at reasonable times at the Company's principal

     certify to the Company and the Guarantors that they have a current
     intention to sell Transfer Restricted Securities or Broker-Dealer Transfer
     Restricted Securities pursuant to a Shelf Registration Statement or

     Offer, the Holders of Broker-Dealer Transfer Restricted Securities, such
     financial and other information of the Company and the Guarantors as
     reasonably requested and cause the Company's and the Guarantors' officers,
     directors and employees to respond to such inquiries as shall be
     reasonably necessary, in the reasonable judgment of counsel to such
     Holders, to conduct a reasonable investigation; provided, however, that
     each such party shall be required to maintain in confidence and not to
     disclose to any other person any

     being confidential, until such time as (A) such information becomes a
     matter of public record (whether by virtue of its inclusion in such
     Registration Statement or otherwise), or (B) such person shall be required
     so to disclose such information pursuant to the subpoena or order of any
     court or other governmental agency or body having jurisdiction over the

               Shelf Registration Statement signed by (y) the respective
               Chairman of the Board, the respective President or any Vice

               Shelf Registration Statement, as the case may be, of counsel for
               the Company covering the matters set forth in paragraphs (c) (d)
               and (e) of Section 7 of the Purchase Agreement and such other
               matter as such parties may reasonably request, and in any event
               including a statement to the effect that such counsel has
               participated in conferences with officers and other
               representatives of the Company, representatives of the
               independent public accountants for the Company, the Initial

               of such Registration Statement and the related Prospectus and
               have considered the matters required to be stated therein and
               the statements contained therein, although such counsel has not
               independently verified the accuracy, completeness or fairness of
               such statements; and that such counsel advises that, on the
               basis of the foregoing (relying as to materiality to a large
               extent upon facts provided to such counsel by officers and other
               representatives of the Company and without independent check or
               verification), no facts came to such counsel's attention that
               caused such counsel to believe that the applicable Registration
               Statement, at the time such Registration Statement or any
               post-effective amendment thereto became effective, and, in the
               case of the Exchange Offer Registration Statement, as of the
               date of Consummation, contained an untrue statement of a
               material fact or omitted to state a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading, or that the Prospectus contained in such
               Registration Statement as of its date and, in the case of the
               opinion dated the date of Consummation of the Exchange Offer, as
               of the date of Consummation, contained an untrue statement of a
               material fact or omitted to state a material fact necessary in
               order to make the statements therein, in light of the
               circumstances under which they were made, not misleading. Such
               counsel may state further that such counsel assumes no
               responsibility for, and has not independently verified, the
               accuracy, completeness or fairness of the financial statements,
               notes and schedules and other financial data included in any
               Registration Statement contemplated by this Agreement or the
               related Prospectus; and

                    (3) a customary comfort letter, dated as of the date of
               Consummation of the Exchange Offer or the date of effectiveness
               of the Shelf Registration Statement, as the case may be, from
               the Company's independent accountants, in the customary form and
               covering matters of the type customarily covered in comfort
               letters by underwriters in connection with primary underwritten
               offerings, and affirming the matters set forth in the comfort
               letters delivered pursuant to Section 7 of the Purchase
               Agreement, without exception;

               (B) set forth in full or incorporated by reference in the
          underwriting agreement, if any, the indemnification provisions and
          procedures of Section 8 hereof with respect to all parties to be
          indemnified pursuant to said Section; and

               (C) deliver such other documents and certificates as may be
          reasonably requested by such parties to evidence compliance with
          clause (A) above and with any customary conditions contained in the
          underwriting agreement or other agreement entered into by the Company
          and the Guarantors pursuant to this clause (x), if any.

     Transfer Restricted Securities, as applicable, under the securities or
     Blue Sky laws of such jurisdictions as the selling Holders of Transfer

     underwriter (including any "qualified independent underwriter") that is
     required to be retained in accordance with the rules and regulations of
     the NASD;

                                      -15-
                                                                    

<PAGE>



          (r) otherwise use their best efforts to comply with all applicable
     rules and regulations of the Commission, and make generally available to
     its security holders, as soon as practicable, a consolidated earnings
     statement meeting the requirements of Rule 158 (which need not be audited)
     for the twelve-month period (A) commencing at the end of any fiscal
     quarter in which Transfer Restricted Securities are sold to underwriters
     in a firm or best efforts Underwritten Offering or (B) if not sold to
     underwriters in such an offering, beginning with the first month of the
     Company's first fiscal quarter commencing after the effective date of the
     Registration Statement;

          (s) cause the Indenture to be qualified under the TIA not later than
     the effective date of the first Registration Statement required by this
     Agreement, and, in connection therewith, cooperate with the Trustee and
     the Holders of Notes to effect such changes to the Indenture as may be
     required for such Indenture to be so qualified in accordance with the
     terms of the TIA; and execute, and use all commercially reasonable efforts
     to cause the Trustee to execute, all documents that may be required to
     effect such changes and all other forms and documents required to be filed
     with the Commission to enable such Indenture to be so qualified in a
     timely manner;

          (t) provide promptly to each Holder upon request each document filed
     with the Commission pursuant to the requirements of Section 13 and Section
     15 of the Exchange Act; and

          (u) cause each Additional Guarantor upon the creation or acquisition
     by the Company of such Additional Guarantor, to execute a counterpart to
     this Agreement in the form attached hereto as Annex A and to deliver such
     counterpart, together with an opinion of counsel as to the enforceability
     thereof against such entity, to the Initial Purchasers no later than five
     business days following the execution thereof.

          Each Holder agrees by acquisition of a Transfer Restricted Security
or Broker-Dealer Transfer Restricted Securities, as applicable, that, upon
receipt of any notice from the Company of the existence of any fact of the kind
described in Section 6(d)(iii)(D) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities or Broker-Dealer
Transfer Restricted Security pursuant to the applicable Registration Statement
until such Holder's receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 6(d)(xvi) hereof, or until it is advised in
writing (the "Advice") by the Company that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus. If so directed by the Company,
each Holder will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies then in such Holder's possession, of the
Prospectus covering such Transfer Restricted Securities or Broker-Dealer
Transfer Restricted Security, as applicable, that was current at the time of
receipt of such notice. In the event the Company shall give any such notice,
the time period regarding the effectiveness of such Registration Statement set
forth in Section 3 or 4 hereof, as applicable, shall be extended by the number
of days during the period from and including the date of the giving of such
notice pursuant to Section 6(d)(iii)(D) hereof to and including the date when
each selling Holder covered by such Registration Statement shall have received
the copies of the supplemented or amended Prospectus contemplated by Section
6(d)(xv) hereof or shall have received the Advice.

          The Company and the Guarantors may require each Holder of Transfer
Restricted Securities or Broker-Dealer Transfer Restricted Securities as to
which any registration is being

                                      -16-
                                                                    

<PAGE>





effected to furnish to the Company such information regarding such Holder and
such Holder's intended method of distribution of the applicable Transfer
Restricted Securities or Broker-Dealer Transfer Restricted Securities as the
Company may from time to time reasonably request in writing, but only to the
extent that such information is required in order to comply with the Act. Each
such Holder agrees to notify the Company as promptly as practicable of (i) any
inaccuracy or change in information previously furnished by such Holder to the
Company or (ii) the occurrence of any event, in either case, as a result of
which any Prospectus relating to such registration contains or would contain an
untrue statement of a material fact regarding such Holder or such Holder's
intended method of distribution of the applicable Transfer Restricted
Securities or Broker-Dealer Transfer Restricted Securities or omits to state
any material fact regarding such Holder or such Holder's intended method of
distribution of the applicable Transfer Restricted Securities or Broker-Dealer
Transfer Restricted Securities required to be stated therein or necessary to
make the statements therein not misleading and promptly to furnish to the
Company any additional information required to correct and update any
previously furnish to the Company any additional information required to
correct and update any previously furnished information or required so that
such Prospectus shall not contain, with respect to such Holder or the
distribution of the applicable Transfer Restricted Securities or Broker-Dealer
Transfer Restricted Securities an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading.

         SECTION 7. REGISTRATION EXPENSES

         All expenses incident to the Company's and the Guarantors' performance
of or compliance with this Agreement will be borne by the Company regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses (including
filings made by any Initial Purchaser or Holder with the NASD (and, if
applicable, the fees and expenses of any "qualified independent underwriter"
and its counsel that may be required by the rules and regulations of the
NASD)); (ii) all fees and expenses of compliance with federal securities and
state Blue Sky or securities laws; (iii) all expenses of printing (including
printing certificates for the Series B Notes to be issued in the Exchange Offer
and printing of Prospectuses), messenger and delivery services; (iv) all fees
and disbursements of counsel for the Company and the Guarantors and the Holders
of Transfer Restricted Securities; and (v) all fees and disbursements of
independent certified public accountants of the Company (including the expenses
of any special audit and comfort letters required by or incident to such
performance).

          The Company will, in any event, bear its and the Guarantors' internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company or the Guarantors.

                                      -17-
                                                                    

<PAGE>



         SECTION 8. INDEMNIFICATION

         8.1 The Company and the Guarantors shall, jointly and severally,
indemnify and hold harmless each Holder of Transfer Restricted Securities or
Broker Dealer Transfer Restricted Securities, its officers and employees and
each person, if any, who controls any such Holders, within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to purchases, sales and
registration of Notes), to which that Holder, officer, employee or controlling
person may become subject, under the Securities Act or otherwise, insofar as
such loss, claim, damage, liability or action arises out of, or is based upon,
(i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any Registration Statement or Prospectus or in any amendment
or supplement thereto or (B) in any blue sky application or other document
prepared or executed by the Company or any Guarantor (or based upon any written
information furnished by the Company or any Guarantor) specifically for the
purpose of qualifying any or all of the Notes under the securities laws of any
state or other jurisdiction (any such application, document or information
being hereinafter called a "Blue Sky Application"), (ii) the omission or
alleged omission to state in any Registration Statement or Prospectus, or in
any amendment or supplement thereto, or in any Blue Sky Application any
material fact required to be stated therein or necessary to make the statements
therein not misleading or (iii) any act or failure to act or any alleged act or
failure to act by any Holder in connection with, or relating in any manner to,
the Notes or the offering contemplated hereby, and which is included as part of
or referred to in any loss, claim, damage, liability or action arising out of
or based upon matters covered by clause (i) or (ii) above (provided that the
Company and the Guarantors shall not be liable under this clause (iii) to the
extent that it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be
taken by such Holder through its gross negligence or willful misconduct), and
shall reimburse each Holder and each such officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by that Holder, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Guarantors shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Registration Statement or Prospectus, or in any
such amendment or supplement, or in any Blue Sky Application, in reliance upon
and in conformity with written information concerning such Holder furnished to
the Company by or on behalf of any Holder specifically for inclusion therein.
The foregoing indemnity agreement is in addition to any liability which the
Company and the Guarantors may otherwise have to any Holder or to any officer,
employee or controlling person of that Holder.

         8.2 Each Holder, severally and not jointly, shall indemnify and hold
harmless the Company and the Guarantors, their respective officers and
employees, each of their respective directors, and each person, if any, who
controls the Company or the Guarantors within the meaning of the Securities
Act, from and against any loss, claim, damage or liability, joint or several,
or any action in respect thereof, to which the Company, the Guarantors or any
such director, officer or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained (A) in any Registration Statement
or Prospectus, or in any amendment or supplement thereto, or (B) in any Blue
Sky Application or (ii) the omission or

                                      -18-
                                                                    

<PAGE>





alleged omission to state in any Registration Statement or Prospectus, or in
any amendment or supplement thereto, or in any Blue Sky Application any
material fact required to be stated therein or necessary to make the statements
therein not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information concerning such
Holders furnished to the Company by or on behalf of that Holder specifically
for inclusion therein, and shall reimburse the Company, the Guarantors and any
such director, officer or controlling person for any legal or other expenses
reasonably incurred by the Company, the Guarantors or any such director,
officer or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action
as such expenses are incurred. The foregoing indemnity agreement is in addition
to any liability which any Holder may otherwise have to the Company, the
Guarantors or any such director, officer, employee or controlling person.

         8.3 Promptly after receipt by an indemnified party under this Section
8 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however,
that the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 8. If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation;
provided, however, any indemnified party shall have the right to employ
separate counsel in any such action and to participate in the defense thereof
but the fees and expenses of such counsel shall be at the expense of the
indemnified party unless (i) the employment thereof has been specifically
authorized by the indemnifying party in writing, (ii) such indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party and in the reasonable judgment of such
counsel it is advisable for such indemnified party to employ separate counsel
or (iii) the indemnifying party has failed to assume the defense of such action
and employ counsel reasonably satisfactory to the indemnified party, in which
case, if such indemnified party notifies the indemnifying party in writing that
it elects to employ separate counsel at the expense of the indemnifying party
shall not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to one local
counsel) at any time for all such indemnified parties, if the indemnified
parties under this Section 8 consist of any Initial Purchaser or any of their
respective officers, employees or controlling persons, or by the Company, if
the indemnified parties under this Section consist of the Company, the
Guarantors or any of their respective directors, officers, employees or
controlling persons. No indemnifying party shall (i) without the prior written
consent

                                      -19-
                                                                    

<PAGE>



of the indemnified parties (which consent shall not be unreasonably withheld),
settle or compromise or consent to the entry of any judgment with respect to
any pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the consent of the indemnifying party or if
there be a final judgment of the plaintiff in any such action, the indemnifying
party agrees to indemnify and hold harmless any indemnified party from and
against any loss or liability by reason of such settlement or judgment.

         8.4 If the indemnification provided for in this Section 8 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Guarantors, on the one hand, and the Holders on
the other, from the offering of the Notes or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Guarantors, on the one
hand and the Holders on the other with respect to the statements or omissions
which resulted in such loss, claim, damage or liability, or action in respect
thereof, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Guarantors, on the one hand and the
Holders on the other with respect to such offering shall be deemed to be in the
same proportion as the total net proceeds from the offering of the Series A
Notes purchased under the Purchase Agreement (before deducting expenses)
received by the Company and the Guarantors, on the one hand, and the total
discounts and commissions received by the Holders with respect to the Series A
Notes purchased under this Agreement, on the other hand, bear to the total
gross proceeds from the offering of the Series A Notes under the Purchase
Agreement, in each case as set forth in the table on the cover page of the
Offering Memorandum. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact relates to information supplied by
the Company, the Guarantors or the Holders, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Company, the Guarantors and the Holders agree
that it would not be just and equitable if contributions pursuant to this
Section 8(d) were to be determined by pro rata allocation (even if the Holders
were treated as one entity for such purpose) or by any other method of
allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section shall be deemed to include, for purposes of
this Section 8(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 8(d), no Holder shall
be required to contribute any amount in excess of the amount by which the net
proceeds received by it in connection with its sale of Notes exceeds the amount
of any damages which such Holder has otherwise paid or become liable to pay by
reason of any untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not

                                      -20-
                                                                    

<PAGE>





guilty of such fraudulent misrepresentation. The Holders' obligations to
contribute as provided in this Section 8(d) are several and not joint.

         SECTION 9. RULE 144A

         The Company and each Guarantor hereby agrees with each Holder of
Transfer Restricted Securities, during any period in which the Company or such
Guarantor is not subject to Section 13 or 15(d) of the Exchange Act within the
two-year period following the Closing Date, and each Holder of Broker-Dealer
Transfer Restricted Securities, for so long as any Broker-Dealer Transfer
Restricted Securities remain outstanding, to make available to any Holder or
beneficial owner of Transfer Restricted Securities or any Holder or
Broker-Dealer Transfer Restricted Securities, in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
from such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A.

         SECTION 10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

         No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities or Broker-Dealer Transfer Restricted Securities, as applicable, on
the basis provided in any underwriting arrangements approved by the Persons
entitled hereunder to approve such arrangements and (b) completes and executes
all reasonable questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up letters and other documents required under the terms of
such underwriting arrangements.

         SECTION 11. SELECTION OF UNDERWRITERS

         The Holders of Transfer Restricted Securities covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering at such Holders' expense. In any such
Underwritten Offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders
of a majority in aggregate principal amount of the Transfer Restricted
Securities included in such offering; provided, that such investment bankers
and managers must be reasonably satisfactory to the Company.

         SECTION 12. MISCELLANEOUS

         12.1 Remedies. The Company and the Guarantors agree that monetary
damages (including the liquidated damages contemplated hereby) would not be
adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Agreement and hereby agree to waive the defense in any
action for specific performance that a remedy at law would be adequate.

         12.2 No Inconsistent Agreements. Neither the Company nor any Guarantor
will, on or after the date of this Agreement, enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the

                                      -21-
                                                                    

<PAGE>



provisions hereof. Except as disclosed in the Final Offering Memorandum,
neither the Company nor any Guarantor has previously entered into any agreement
granting any registration rights with respect to its securities to any Person.
The rights granted to the Holders hereunder do not in any way conflict with and
are not inconsistent with the rights granted to the holders of the Company's or
any Guarantor's securities under any agreement in effect on the date hereof.

         12.3 Adjustments Affecting the Notes. The Company and the Guarantors
will not take any action, or permit any change to occur, with respect to the
Notes that would materially and adversely affect the ability of the Holders to
Consummate any Exchange Offer.

         12.4 Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given unless the Company has obtained the
written consent of Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities. Notwithstanding the foregoing, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders whose securities are being tendered pursuant to the Exchange
Offer and that does not affect directly or indirectly the rights of other
Holders whose securities are not being tendered pursuant to such Exchange Offer
may be given by the Holders of a majority of the outstanding principal amount
of Transfer Restricted Securities being tendered or registered.

         12.5 Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

(the "Closing Date"), in the form of Exhibit A hereto, for so long as such
Series A Notes constitute "Transfer Restricted Securities" (as defined in the
Registration Rights Agreement). Pursuant to the Registration Rights Agreement,
the Company and the Guarantors will agree to file with the Securities and
Exchange Commission (the "Commission") under the circumstances set forth
therein, (i) a registration statement under the Securities Act (the "Exchange
Offer Registration Statement") relating to the Company's 8% Senior Subordinated
Notes due 2008 (the "Series B Notes" and, together with the Series A Notes, the
"Notes") to be offered in exchange for the Series A Notes, (such offer to
exchange being referred to collectively as the "Registered Exchange Offer") and
(ii) a shelf registration statement pursuant to Rule 415 under the Securities
Act (the "Shelf Registration Statement") relating to the resale by certain
holders of the Series A Notes, and to use their best efforts to cause such
Registration Statements to be declared effective. This Agreement, the Notes,
the Guarantees (as defined herein), the Indenture and the Registration Rights
Agreement are hereinafter referred to collectively as the "Operative
Documents." This is to confirm the agreements concerning the purchase of the
Series A Notes from the Company by you.

by the Company and each of the Guarantors, and when duly executed by the proper

by the Initial Purchasers) and delivered by the Company and each Guarantor,

Guarantor, enforceable against the Company and each Guarantor in accordance
with its terms, subject to the effects of bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) or an implied covenant of good
faith and fair dealing and except as rights to indemnity and contribution
thereunder may be limited by Federal or state securities laws or principles of
public policy.

the Company and when duly executed by the Company in accordance with the terms
of the Indenture and, assuming due authentication of the Series A Notes by the
Trustee, upon delivery to the Initial Purchasers against payment therefor in
accordance with the terms hereof will constitute valid and binding obligations
of the Company entitled to the benefits of the Indenture and enforceable
against the Company in accordance with their terms, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and

in any jurisdiction, or the initiation or threatening of any proceeding for
such purpose by the Commission or any state securities commission or other
regulatory authority, and (ii) the happening of any event that makes any
statement of a material fact made in the Offering Memorandum untrue or which
requires the making of any additions to or changes in the Offering Memorandum
in order to make the statements therein, in light of the circumstances under
which they were made, not misleading. The Company shall use all commercially
reasonable efforts to prevent the issuance of any stop order or order
suspending the qualification or exemption of the Series A Notes or Series A
Guarantees under any state securities or Blue Sky laws and, if at any time any
state securities commission shall issue any stop order suspending the
qualification or exemption of the Series A Notes or Series A Guarantees under
any state securities or Blue Sky laws, the Company shall use every reasonable
effort to obtain the withdrawal or lifting of such order at the earliest
possible time.

         each such subsidiary's stock ledger and minute book, all such shares
         are held of record by the Company and/or a subsidiary of the Company;

                  (iii) The Indenture has been duly authorized, executed and
         delivered by the Company and, assuming that the Indenture is the valid
         and legally binding obligation of the

                  (ix) To such counsel's knowledge, there are no contracts or
         documents of a character required by the Securities Act or by the

         with all of the provisions of this Agreement and the other Operative

         and thereby will not breach or result in a default under any
         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument which was filed as an exhibit to the Company's most
         recent Registration Statement on Form S-1 or is identified as such on
         a list provided to such counsel to which the Company or any of its
         subsidiaries is a party or by which the Company or any of its
         subsidiaries is bound or to which any of the property or assets of the
         Company or any of its subsidiaries is subject, nor will such actions
         violate the Certificate of Incorporation or By-Laws or other
         organizational documents of the Company or any of its subsidiaries or
         any federal or New York statute, the Delaware Limited Liability
         Company Act or the Delaware General Corporation Law or any rule or
         regulation that has been issued pursuant to any federal or New York
         statute, the Delaware Limited Liability Company Act or the Delaware
         General Corporation Law or any order known to such counsel issued
         pursuant to any federal or New York statute, the Delaware Limited
         Liability Company Act or the Delaware General Corporation Law by any
         court or governmental agency or body or court having jurisdiction over
         the Company or any of its subsidiaries or any of their properties or
         assets; and no consent, approval, authorization, order, registration
         or qualification of or with any federal or New York governmental
         agency or body or any Delaware governmental agency or body acting
         pursuant to the Delaware Limited Liability Company Act, the Delaware
         General Corporation Law or, to such counsel's knowledge, any federal
         or New York court or any Delaware court acting pursuant to the
         Delaware Limited Liability Company Act, the Delaware General
         Corporation Law is required for issuance and sale of the Notes by the
         Company (and the guarantee of such Notes by the Guarantors), except
         for the registration under the Securities Act of the Series B Notes in
         accordance with the Registration Rights Agreement and the
         qualification of the Indenture under the 1939 Act, and such consents,
         approvals, authorizations, registrations or qualifications as may be


                                      18
<PAGE>


         required state securities or Blue Sky laws in connection with the
         purchase and distribution of the Series A Notes and Series A
         Guarantees by the Initial Purchasers. The opinions set forth in this
         paragraph are based upon our consideration of only those statutes,
         rules and regulations which, in such counsel's experience, are
         normally applicable to securities underwriting transactions.

                  (xiii) No registration of the Series A Notes under the
         Securities Act and no qualification of the Indenture under the 1939
         Act is required for the offer and sale of the Series A Notes by the
         Company to the Initial Purchasers or the reoffer and resale of the
         Series A Notes by the Initial Purchasers to the initial purchasers
         therefrom solely in the manner contemplated by the Offering
         Memorandum, the Purchase Agreement and the Indenture.

         In rendering such opinion, such counsel may state that its opinion is
         limited to matters governed by the federal laws of the United States
         and the laws of the State of New York, the Delaware Limited Liability
         Company Act and the Delaware General Corporation Law.

         Such counsel shall also have furnished to the Initial Purchasers a
         written statement, addressed to the Initial Purchasers and dated the
         Closing Date. Such counsel has not independently verified the
         accuracy, completeness or fairness of the statements made or included
         in the Offering Memorandum and take no responsibility therefor, except
         as and to the extent set forth in paragraph (vii) above. In the course
         of the preparation by the Company of the Offering Memorandum, such
         counsel participated in conferences with certain officers and
         employees of the Company, with representatives of
         PricewaterhouseCoopers LLP, Ernst & Young LLP, KPMG Peat Marwick LLP,
         Grant Thornton LP and with counsel to the Company. Based upon such
         counsel's examination of the Offering Memorandum, such counsel's
         investigations made in connection with the preparation of the Offering
         Memorandum and such counsel's participation in the conferences
         referred to above, such counsel has no reason to believe that the
         Offering Memorandum, as of its date and as of the Closing Date,
         contains or contained any untrue statement of a material fact or omits
         or omitted to state any material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, except that in each case such counsel need
         not express belief with respect to the financial statements or other
         financial data contained in the Offering Memorandum.

         (d) Christopher C. Cambria, General Counsel of the Company, shall have
furnished to the Initial Purchasers his written opinion, as General Counsel to
the Company, addressed to the Initial Purchasers and dated the Closing Date, in
form and substance reasonably satisfactory to the Initial Purchasers, to the
effect that:

                  (i) To such counsel's knowledge, the Company and each of its
         subsidiaries have good and marketable title to all property (real and
         personal) described in the Offering Memorandum as being owned by them,
         free and clear of all liens, claims, security interests or other
         encumbrances except such as are described in the Offering Memorandum
         or, to the extent that any such liens, claims, security interests or
         other encumbrances would not have a Material Adverse Effect



                                      19
<PAGE>

         (individually or in the aggregate) and all the material property
         described in the Offering Memorandum as being held under lease by the
         Company and its subsidiaries is held by them under valid, subsisting
         and enforceable leases, with only such exceptions as would not have a
         Material Adverse Effect (individually or in the aggregate);

                  (ii) To such counsel's knowledge and except as otherwise
         disclosed in the Offering Memorandum, there are no legal or
         governmental proceedings pending or threatened, against the Company or
         any of its subsidiaries or to which the Company or any of its
         subsidiaries is a party or of which any property or assets of the
         Company or any of its subsidiaries is the subject which, if determined
         adversely to the Company or any of its subsidiaries, are reasonably
         likely to cause a Material Adverse Effect;

                  (iii) To such counsel's knowledge and except as otherwise
         disclosed in the Offering Memorandum, there are no contracts,
         agreements or understandings between the Company and any person
         granting such person the right to require the Company to include such
         person's securities in the securities registered pursuant to the
         Exchange Offer Registration Statement or the Shelf Registration
         Statement;

                  (iv) None of the issue and sale of the Notes and Guarantees
         being delivered on such Closing Date by the Company and the Guarantors
         and the compliance by the Company and the Guarantors, as applicable,
         with all of the provisions of this Agreement and the consummation of
         the transactions contemplated hereby and thereby requires any consent,
         approval, authorization or other order of, or registration or filing
         with, any federal court, federal regulatory body, federal
         administrative agency or other federal governmental official having
         authority over government procurement matters (provided, that the
         opinion contained in this paragraph (iv) may be delivered by other
         counsel reasonably satisfactory to the Initial Purchasers).

         (e) The Initial Purchasers shall have received from Latham & Watkins,
counsel for the Initial Purchasers, such opinion or opinions, dated the Closing
Date, with respect to the issuance and sale of the Series A Notes, the Series A
Guarantees, the Offering Memorandum and other related matters as the Initial
Purchasers may reasonably require, and the Company shall have furnished to such
counsel such documents as they reasonably request for the purpose of enabling
them to pass upon such matters.

         (f) On the Closing Date, the Initial Purchasers shall have received
from PricewaterhouseCoopers LLP, a letter, in form and substance satisfactory
to the Initial Purchasers, addressed to the Initial Purchasers (i) confirming
that they are independent public accountants under Rule 101 of the AICPA's Code

                  (i) The representations and warranties of the Company and the
         Guarantors in Section 1 are true and correct as of the Closing Date;
         the Company and the Guarantors have complied with all their agreements
         contained herein; and the conditions set forth in Sections 7(a) and
         7(k) have been fulfilled; and

                  (ii) They have carefully examined the Offering Memorandum
         and, in their opinion (A) the Offering Memorandum as of its date and
         as of the Closing Date, did not include any untrue statement of a
         material fact and did not omit to state a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, and (B) since the date of the Offering Memorandum, no
         event has occurred which should have been set forth in a supplement or
         amendment to the Offering Memorandum.

         (k) (i) Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included in
the Offering Memorandum any material loss or interference with its business
from fire, explosion, flood or other calamity, whether or not covered by
insurance, or from any labor dispute or court or governmental action, order or
decree, otherwise than as set forth or contemplated in the Offering Memorandum
or (ii) since such date there shall not have been any change in the capital
stock or long-term debt of the Company or any of its


                                      21
<PAGE>

subsidiaries or any change, or any development involving a prospective change,
in or affecting the business, management, financial position, stockholders'
equity or results of operations of the Company and its subsidiaries taken as a
whole, otherwise than as set forth or contemplated in the Offering Memorandum,
the effect of which, in any such case described in clause (i) or (ii), is, in
the judgment of the Initial Purchasers, so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the
delivery of the Notes and the Guarantees being delivered on the Closing Date on
the terms and in the manner contemplated in the Offering Memorandum.

         (l) Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Company's debt
securities by any "nationally recognized statistical rating organization," as
that term is defined by the Commission for purposes of Rule 436(g)(2) under the
Securities Act and (ii) no such organization shall have publicly announced that
it has under surveillance or review, with possible negative implications, its
rating of any of the Company's debt securities.

         (m) Subsequent to the execution and delivery of this Agreement there
shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange or the American Stock Exchange or in
the over-the-counter market, or trading in any securities of the Company on any
exchange or in the over-the-counter market, shall have been suspended or
minimum prices shall have been established on any such exchange or such market
by the Commission, by such exchange or by any other regulatory body or
governmental authority having jurisdiction, (ii) a banking moratorium shall
have been declared by Federal or state authorities, (iii) the United States
shall have become engaged in hostilities, there shall have been an escalation
in hostilities involving the United States or there shall have been a
declaration of a national emergency or war by the United States or (iv) there
shall have occurred such a material adverse change in general economic,
political or financial conditions (or the effect of international conditions on
the financial markets in the United States shall be such) as to make it, in the
judgment of the Initial Purchasers, impracticable or inadvisable to proceed
with the public offering or delivery of the Notes being delivered on the
Closing Date on the terms and in the manner contemplated in the Offering
Memorandum.

         All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably
satisfactory to counsel for the Initial Purchasers.

         8. Indemnification and Contribution.

         (a) The Company and the Guarantors shall jointly and severally
indemnify and hold harmless each Initial Purchaser, its officers and employees
and each person, if any, who controls any Initial Purchaser within the meaning
of the Securities Act, from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof (including, but not limited
to, any loss, claim, damage, liability or action relating to purchases and
sales of Notes and Guarantees), to which that Initial Purchaser, officer,
employee or controlling person may become subject, under the Securities Act or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained (A) in the Offering Memorandum or in any amendment or
supplement thereto or (B) in any blue sky


                                      22
<PAGE>

application or other document prepared or executed by the Company (or based
upon any written information furnished by the Company) specifically for the
purpose of qualifying any or all of the Series A Notes under the securities
laws of any state or other jurisdiction (any such application, document or
information being hereinafter called a "Blue Sky Application"), (ii) the
omission or alleged omission to state in the Offering Memorandum, or in any
amendment or supplement thereto, or in any Blue Sky Application any material
fact required to be stated therein or necessary to make the statements therein
not misleading or (iii) any act or failure to act or any alleged act or failure
to act by any Initial Purchaser in connection with, or relating in any manner
to, the Notes or the offering contemplated hereby, and which is included as
part of or referred to in any loss, claim, damage, liability or action arising
out of or based upon matters covered by clause (i) or (ii) above (provided that
the Company and the Guarantors shall not be liable under this clause (iii) to
the extent that it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be
taken by such Initial Purchaser through its gross negligence or willful
misconduct), and shall reimburse each Initial Purchaser and each such officer,
employee or controlling person promptly upon demand for any legal or other
expenses reasonably incurred by that Initial Purchaser, officer, employee or
controlling person in connection with investigating or defending or preparing
to defend against any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the Company and the Guarantors
shall not be liable in any such case to the extent that any such loss, claim,
damage, liability or action arises out of, or is based upon, any untrue
statement or alleged untrue statement or omission or alleged omission made in
the Offering Memorandum, or in any such amendment or supplement, or in any Blue
Sky Application, in reliance upon and in conformity with written information
concerning such Initial Purchaser furnished to the Company by or on behalf of
any Initial Purchaser specifically for inclusion therein. The foregoing
indemnity agreement is in addition to any liability which the Company and the
Guarantors may otherwise have to any Initial Purchaser or to any officer,
employee or controlling person of that Initial Purchaser.

         (b) Each Initial Purchaser, severally and not jointly, shall indemnify
and hold harmless the Company, the Guarantors, their officers and employees,
each of their directors, and each person, if any, who controls the Company and
the Guarantors within the meaning of the Securities Act, from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Company, the Guarantors or any such director, officer or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in the Offering Memorandum or in any amendment or supplement
thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged
omission to state in the Offering Memorandum, or in any amendment or supplement
thereto, or in any Blue Sky Application any material fact required to be stated
therein or necessary to make the statements therein not misleading, but in each
case only to the extent that the untrue statement or alleged untrue statement
or omission or alleged omission was made in reliance upon and in conformity
with written information concerning such Initial Purchaser furnished to the
Company by or on behalf of that Initial Purchaser specifically for inclusion
therein, and shall reimburse the Company, the Guarantors and any such director,
officer or controlling person for any legal or other expenses reasonably
incurred by the Company, such Guarantor or any such director, officer or
controlling person in connection with investigating or defending or preparing
to defend against any such loss, claim, damage, liability or action as such
expenses are incurred. The foregoing indemnity agreement is in

                                      23
<PAGE>


addition to any liability which any Initial Purchaser may otherwise have to the
Company, the Guarantors or any such director, officer, employee or controlling
person.

         (c) Promptly after receipt by an indemnified party under this Section
8 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however,
that the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 8. If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation;
provided, however, any indemnified party shall have the right to employ
separate counsel in any such action and to participate in the defense thereof
but the fees and expenses of such counsel shall be at the expense of the
indemnified party unless (i) the employment thereof has been specifically
authorized by the indemnifying party in writing, (ii) such indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party and in the reasonable judgment of such
counsel it is advisable for such indemnified party to employ separate counsel
or (iii) the indemnifying party has failed to assume the defense of such action
and employ counsel reasonably satisfactory to the indemnified party, in which
case, if such indemnified party notifies the indemnifying party in writing that
it elects to employ separate counsel at the expense of the indemnifying party
shall not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to one local
counsel) at any time for all such indemnified parties, which firm shall be
designated in writing by Lehman Brothers Inc., if the indemnified parties under
this Section 8 consist of any Initial Purchaser or any of their respective
officers, employees or controlling persons, or by the Company, if the
indemnified parties under this Section consist of the Company, the Guarantors
or any of the Company's or the Guarantors' directors, officers, employees or
controlling persons. No indemnifying party shall (i) without the prior written
consent of the indemnified parties (which consent shall not be unreasonably
withheld), settle or compromise or consent to the entry of any judgment with
respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified parties are actual or potential parties to such
claim or action) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action, suit or proceeding, or (ii) be liable for any settlement
of any such action effected without its written consent (which consent shall
not be unreasonably withheld), but if settled with the consent of the
indemnifying party or if there be a final judgment of


                                      24
<PAGE>

the plaintiff in any such action, the indemnifying party agrees to indemnify
and hold harmless any indemnified party from and against any loss or liability
by reason of such settlement or judgment.

         (d) If the indemnification provided for in this Section 8 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Guarantors on the one hand and the Initial
Purchasers on the other from the offering of the Series A Notes and the Series
A Guarantees or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company and the Guarantors on the one hand and the
Initial Purchasers on the other with respect to the statements or omissions
which resulted in such loss, claim, damage or liability, or action in respect
thereof, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Guarantors on the one hand and the
Initial Purchasers on the other with respect to such offering shall be deemed
to be in the same proportion as the total net proceeds from the offering of the
Series A Notes purchased under this Agreement (before deducting expenses)
received by the Company and the Guarantors, on the one hand, and the total
discounts and commissions received by the Initial Purchasers with respect to
the Series A Notes and the Series A Guarantees purchased under this Agreement,
on the other hand, bear to the total gross proceeds from the offering of the
Series A Notes under this Agreement, in each case as set forth in the table on
the cover page of the Offering Memorandum. The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company, the Guarantors or the Initial
Purchasers, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the Guarantors and the Initial Purchasers agree that it would not
be just and equitable if contributions pursuant to this Section 8(d) were to be
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the loss, claim,
damage or liability, or action in respect thereof, referred to above in this
Section shall be deemed to include, for purposes of this Section 8(d), any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8(d), no Initial Purchaser shall
be required to contribute any amount in excess of the amount by which the total
price at which the Series A Notes purchased by it was resold to Eligible
Purchasers exceeds the amount of any damages which such Initial Purchaser has
otherwise paid or become liable to pay by reason of any untrue or alleged
untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Initial Purchasers'
obligations to contribute as provided in this Section 8(d) are several in
proportion to their respective underwriting obligations and not joint.

                                      25
<PAGE>

         (e) The Initial Purchasers severally confirm and the Company and the
Guarantors acknowledge that the last paragraph on the cover page, the
stabilization legend on page iii and the last two paragraphs under the caption
"Plan of Distribution" constitute the only information concerning such Initial
Purchasers furnished in writing to the Company by or on behalf of the Initial
Purchasers specifically for inclusion in the Offering Memorandum.

         9. Termination. The obligations of the Initial Purchasers hereunder
may be terminated by Lehman Brothers Inc. by notice given to and received by
the Company prior to delivery of and payment for the Series A Notes and the
Series A Guarantees if, prior to that time, any of the events described in
Sections 7(k), 7(m) or 7(n), shall have occurred, the lenders under the Senior
Credit Agreement shall not have consented to the issuance and sale of the Notes
and the use of proceeds therefrom or if the Initial Purchasers shall decline to
purchase the Series A Notes for any reason permitted under this Agreement. The
obligations of the Company and the Guarantors hereunder may be terminated by
the Company by notice given to and received by Lehman Brothers Inc. prior to
delivery of and payment for the Series A Notes and the Series A Guarantees if,
prior to that time, the lenders under the Senior Credit Agreement shall not
have consented to the issuance and sale of the Notes and the use of proceeds
therefrom.

         10. Reimbursement of Initial Purchasers' Expenses. If the Company and
the Guarantors shall fail to tender the Series A Notes and the Series A
Guarantees for delivery to the Initial Purchasers by reason of any failure,
refusal or inability on the part of the Company and the Guarantors to perform
any agreement on its part to be performed, or because any other condition of
the Initial Purchasers' obligations hereunder required to be fulfilled by the
Company and the Guarantors is not fulfilled, the Company and the Guarantors
will reimburse the Initial Purchasers for all reasonable out-of-pocket expenses
(including fees and disbursements of counsel) incurred by the Initial
Purchasers in connection with this Agreement and the proposed purchase of the
Series A Notes and the Series A Guarantees, and upon demand the Company and the
Guarantors shall pay the full amount thereof to Lehman Brothers Inc.

         11. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

                  (a) if to the Initial Purchasers, shall be delivered or sent

         Any such statements, requests, notices or agreements shall take effect
at the time of receipt thereof. The Company shall be entitled to act and rely
upon any request, consent, notice or agreement given or made on behalf of the
Initial Purchasers by Lehman Brothers Inc.

the Company and the Guarantors contained in this Agreement shall also be deemed
to be for the benefit of the person or persons, if any, who control any Initial
Purchaser within the meaning of Section 15 of the Securities Act and (B) the
indemnity agreement of the Initial Purchasers contained in Section 8(c) of this
Agreement shall be deemed to be for the benefit of directors of the Company and
the Guarantors and any person controlling the Company and the Guarantors within

intended or shall be construed to give any person, other than the persons
referred to in this Section 12, any legal or equitable right, remedy or claim

         13. Survival. The respective indemnities, representations, warranties
and agreements of the Company, the Guarantors and the Initial Purchasers
contained in this Agreement or made by or on behalf on them, respectively,
pursuant to this Agreement, shall survive the delivery of and payment for the
Notes and the Guarantees and shall remain in full force and effect, regardless
of any investigation made by or on behalf of any of them or any person
controlling any of them.

         14. Definition of the Terms "Business Day" and "Subsidiary." For
