                        L-3 COMMUNICATIONS CORPORATION 

                  8 1/2% SENIOR SUBORDINATED NOTES DUE 2008 

                   INTEREST PAYABLE MAY 15 AND NOVEMBER 15 

   The 8 1/2% Senior Subordinated Notes due 2008 (the "Notes") are being 
offered (the "Notes Offering") by L-3 Communications Corporation ("L-3 
Communications"), a wholly-owned subsidiary of L-3 Communications Holdings, 
Inc. ("Holdings"). The payment of principal, premium, if any, and interest on 
the Notes will be guaranteed (the "Guarantees") on a senior subordinated 
basis by all of L-3 Communications' Restricted Subsidiaries, including 
Hygienetics Environmental Services, Inc., L-3 Communications ILEX Systems, 
Inc. and Southern California Microwave, Inc. (the "Guarantors"), other than 
Foreign Subsidiaries. Interest on the Notes will be payable semi-annually on 
May 15 and November 15 of each year, commencing November 15, 1998. The Notes 
will be redeemable at the option of L-3 Communications, in whole or in part, 
at any time on or after May 15, 2003, at the redemption prices set forth 
herein, plus accrued and unpaid interest, if any, to the date of redemption. 
In addition, prior to May 15, 2001, L-3 Communications may redeem up to 35% 
of the aggregate principal amount of Notes at the redemption price set forth 
herein plus accrued and unpaid interest, if any, through the redemption date 
with the net cash proceeds of one or more Equity Offerings. The Notes will 
not be subject to any mandatory sinking fund. 

   In the event of a Change of Control, each holder of Notes will have the 
right, at the holder's option, to require L-3 Communications to purchase such 
holder's Notes at a purchase price equal to 101% of the principal amount 
thereof, plus accrued and unpaid interest, if any, to the date of purchase. 
See "Description of the Notes". 

   The Notes will be general unsecured obligations of L-3 Communications, 
subordinate in right of payment to all existing and future Senior Debt of L-3 
Communications. As of March 31, 1998, after giving pro forma effect to the 
1998 Acquisitions and the Offerings, and application of the net proceeds 
therefrom, L-3 Communications would have had approximately $441.2 million of 
indebtedness outstanding, of which $34.9 million would have been Senior Debt 
(excluding letters of credit). See "Capitalization". 

   Concurrently with the Notes Offering, Holdings is publicly offering in the 
United States and internationally 6,000,000 shares of its Common Stock, par 
value $.01 per share (the "Common Stock"). The closing of the Notes Offering 
is conditioned upon the closing of the offering of Common Stock (the "Common 
Stock Offering" and, together with the Notes Offering, the "Offerings"). 
Prior to the consummation of the Common Stock Offering, affiliates of Lehman

                                 THE COMPANY 

   L-3 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, 
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. 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 U.S. 
Department of Defense (the "DoD"), selected U.S. government (the 
"Government") intelligence agencies, major aerospace/defense prime 
contractors, foreign governments and commercial customers. In 1997, L-3 had 
pro forma sales of $894.0 million and pro forma EBITDA (as defined in 
footnote 5 under "Selected Financial Information") of $95.1 million. The 
Company's pro forma funded backlog as of December 31, 1997 was $638.1 
million. These results reflect internal growth as well as the execution of 
the Company's strategy of acquiring businesses that complement or extend 
L-3's product lines. 

   The Company's business areas enjoy proprietary technologies and 
capabilities and have leading positions in their respective primary markets. 
Management has organized the Company's operations into two primary business 
areas: Secure Communication Systems and Specialized Communication Products. 
In 1997, the Secure Communication Systems and Specialized Communication 
Products business areas generated approximately $456.0 million and $438.0 
million of pro forma sales, respectively, and $52.3 million and $42.8 million 
of pro forma EBITDA, respectively. In addition, the Company is seeking to 
expand its products and technologies in commercial markets. See "--Emerging 
Commercial Products" below. 

   SECURE COMMUNICATION SYSTEMS. L-3 is the established leader in secure, 
high data rate communications in support of military and other national 
agency reconnaissance and surveillance applications. The Company's Secure 
Communication Systems operations are located in Salt Lake City, Utah, Camden, 
New Jersey and Shrewsbury, New Jersey. These operations are predominantly 
cost plus, sole source contractors supporting long-term programs for the U.S. 
Armed Forces and classified customers. The Company's major secure 
communication programs and systems include: secure data links for airborne, 
satellite, ground-and sea-based information collection and transmission; 
strategic and tactical signal intelligence systems that detect, collect, 
identify, analyze and disseminate information and related support contracts 
for military and national agency intelligence efforts; as well as secure 
telephone and network equipment. The Company believes that it has developed 
virtually every high bandwidth data link used by the military for 
surveillance and reconnaissance in operation today. L-3 is also a leading 
supplier of communication software support services to military and related 
government intelligence markets. In addition to these core Government 
programs, L-3 is leveraging its technology base by 

                                       1
<PAGE>
expanding into related commercial communication equipment markets, including 
applying its high data rate communications and archiving technology to the 
medical image archiving market and its wireless communication expertise to 
develop local wireless loop telecommunications equipment. 

   SPECIALIZED COMMUNICATION PRODUCTS. This business area includes (i) 
Microwave Components, (ii) Avionics and Ocean Systems and (iii) Telemetry, 
Instrumentation and Space Products operations of the Company. 

   Microwave Components. L-3 is the preeminent worldwide supplier of 
commercial off-the-shelf, high performance microwave components and frequency 
monitoring equipment. L-3's microwave products are sold under the 
industry-recognized Narda brand name through a standard catalog to wireless, 
industrial and military communication markets. L-3 also provides 
state-of-the-art communication components including channel amplifiers and 
frequency filters for the commercial communications satellite market. 
Approximately 76% of Microwave Components sales is made to commercial 
customers, including Loral Space & Communications, Ltd., Motorola, Inc. 
("Motorola"), Lucent Technologies Inc. ("Lucent"), AT&T Corp. ("AT&T") and 
Lockheed Martin Corporation ("Lockheed Martin"). 

   Avionics and Ocean Systems. Avionics and Ocean Systems include the 
Company's Aviation Recorders, Display Systems, Antenna Systems and Acoustic 
Undersea Warfare Systems operations. L-3 is the world's leading manufacturer 
of commercial cockpit voice and flight data recorders ("black boxes"). These 
recorders are sold under the Fairchild brand name both on an original 
equipment manufacturer ("OEM") basis to aircraft manufacturers as well as 
directly to the world's major airlines for their existing fleets of aircraft. 
L-3's aviation recorders are also installed on military transport aircraft 
throughout the world. L-3 provides military and high-end commercial displays 
for use on a number of DoD programs including the F-14, V-22, F-117 and E-2C. 
Further, L-3 manufactures high performance surveillance antennas and related 
equipment for U.S. Air Force, U.S. Army and U.S. Navy aircraft including the 
F-15, F-16, AWACS, E-2C and B-2, as well as the U.K.'s maritime patrol 
aircraft. L-3 is also 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. 

   Telemetry, Instrumentation and Space Products. The Company's 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 parameter 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. L-3 is also a leading global satellite communications 
systems and services provider offering systems and services used in satellite 
transmission of voice, video and data. 

   EMERGING COMMERCIAL PRODUCTS. Building upon its core technical expertise 
and capabilities, the Company is seeking to expand into several closely 
aligned commercial business areas and applications. Emerging Commercial 
Products currently include the following three niche markets: (i) medical 
archiving and simulation systems; (ii) local wireless loop telecommunications 
equipment; and (iii) airport security equipment. These commercial products 
were developed based on technology used in the Company's military businesses 
with relatively small incremental financial investments. The Company is 
applying its technical capabilities in high data rate communications and 
archiving technology developed in its Secure Communication Systems business 
area to the medical image archiving market jointly with the General Electric 
Company's ("GE") medical systems business ("GE Medical Systems"). Based on 
secure, high data rate communication technology also developed in its Secure 
Communication Systems business area, the Company has 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 non-existent. L-3 has completed the 
development phase for the local wireless loop telecommunications equipment 
and made its initial shipment in January 1998. In addition, the Federal 
Aviation Administration (the "FAA") has awarded the Company a development 
contract for next 


                                       2
<PAGE>
generation airport security equipment for explosive detection. L-3 has 
shipped two prototype test units and FAA certification testing commenced in 
the first quarter of 1998. To date, revenues generated from L-3's Emerging 
Commercial Products have not been, in the aggregate, material to the Company. 

INDUSTRY OVERVIEW 

   The defense industry has recently 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 digital command and control communications 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. According to Federal Sources, an independent private 
consulting group, the defense budget for command, control, communications and 
intelligence ("C(3)I") is expected to increase from $31.0 billion in the 
fiscal year ended September 30, 1997 to $42.0 billion in the fiscal year 
ended September 30, 2002, a compound annual growth rate of 6.3%. 

   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 businesses by AlliedSignal Inc. ("AlliedSignal"), Ceridian 
Corporation ("Ceridian"), 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 

   In 1997, management 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 

                                       3
<PAGE>
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 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 65% of the Company's 
    total pro forma 1997 sales were generated from sole source contracts. 
    L-3's customer satisfaction and excellent performance record are evidenced 
    by its performance-based award fees exceeding 90% 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 (excluding the 
    1998 Acquisitions) has experienced a contract award win rate in 1997 in 
    excess of 60% 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 and facilities expenses, 
    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. Over 
    the past three years, 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 2,000 
    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. 


                                       4
<PAGE>
     o  MAINTAIN DIVERSIFIED BUSINESS MIX. The Company enjoys a diverse 
    business mix with a limited program exposure, a favorable balance of cost 
    plus and fixed price contracts, a significant sole source follow-on 
    business and an attractive customer profile. The Company's largest 
    program, representing 13% of 1997 pro forma sales, is a long-term, sole 
    source, cost plus contract for the U-2 Program. No other program 
    represented more than 7% of pro forma 1997 sales. Further, the Company's 
    pro forma sales mix of contracts in 1997 was 36% cost plus and 64% 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 62% and commercial and federal 
    (non-DoD) sales accounting for 38% of 1997 pro forma sales. 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, 
    a number of mezzanine companies were sold: 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") and TASC Inc., a 
    subsidiary of Primark Corporation, to Litton Industries, Inc. ("Litton"). 
    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. 

RECENT DEVELOPMENTS 

   Since the formation of the Company in April 1997, the Company has actively 
pursued its acquisition strategy. The Company recently purchased the assets 
and liabilities of three businesses described below which collectively 
comprise the "1998 Acquisitions". The combined purchase price for the 1998

 (6)    EBITDA is defined as operating income plus depreciation expense and 
        amortization expense (excluding the amortization of deferred debt 
        issuance costs) and the nonrecurring, noncash compensation charge of 
        $4.4 million recorded effective April 1, 1997. EBITDA is not a

        operating activities as determined in accordance with generally 
        accepted accounting principles as a measure of profitability or

        management believes it to be a useful indicator of the Company's 
        ability to meet debt service and capital expenditure requirements. 
 (7)    For purposes of this computation, earnings consist of income before

        the pro forma EBITDA and cash interest expense for the year ended 
        December 31, 1997 and the three months ended March 31, 1998 and 
        deducting the pro forma EBITDA and cash interest expense for the

        forma EBITDA for the three months ended March 31, 1997, depreciation 
        expense and amortization expense were $6.0 million and $2.7 million, 
        respectively. The historical ratios have been calculated by adding 
        historical EBITDA and cash interest expense for the nine months ended 
        December 31, 1997 and the three months ended March 31, 1998.

                                 RISK FACTORS 

   Prospective investors should consider carefully, in addition to the other 
information contained in this Prospectus, the following factors before 
deciding to invest in the Notes. 

SUBSTANTIAL LEVERAGE 

   The Company is highly leveraged as a result of substantial indebtedness 
incurred in connection with the L-3 Acquisition and the 1998 Acquisitions. 
After giving pro forma effect to the L-3 Acquisition, the 1998 Acquisitions 
and the Offerings, the Company would have had $441.2 million of indebtedness 
outstanding, of which $34.9 million would have been Senior Debt (excluding 
letters of credit), and the Company's pro forma earnings would have been 
insufficient to cover pro forma fixed charges by $0.2 million for the three 
months ended March 31, 1998. The Company may incur additional indebtedness in 
the future, subject to limitations imposed by its debt instruments, including 
the Senior Credit Facilities and the Indenture. 

   Based upon the current level of operations and anticipated improvements, 
management believes that the Company's cash flow from operations, together 
with proceeds from the Offerings and available borrowings under the Revolving 
Credit Facility, 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, at least for 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 (including the 1997 Notes and 
the Notes) or obtain additional financing. The Company's ability to make 
scheduled principal payments of, to pay interest on or to refinance its 
indebtedness (including the 1997 Notes and the Notes) depends on its future 
performance and financial results, which, to a certain extent, are subject to 
general conditions in or affecting the defense industry and to general 
economic, political, financial, competitive, legislative and regulatory 
factors beyond its control. There can be no assurance that sufficient funds 
will be available to enable the Company to service its indebtedness, 
including the Notes, or make necessary capital expenditures and program and 
other discretionary investments. See "Management's Discussion and Analysis of 
Financial Condition and Results of Operations". 

   The degree to which the Company is leveraged could have important 
consequences to Holders of the Notes, including, but not limited to, the 
following: (i) a substantial portion of the Company's cash flow from 
operations will be required to be dedicated to debt service and will not be 
available for other purposes including capital expenditures, research and 
development expenditures, and program and other discretionary investments; 
(ii) the Company's ability to obtain additional financing in the future could 
be limited; (iii) certain of the Company's borrowings are at variable rates 
of interest, which could result in higher interest expense in the event of 
increases in interest rates; (iv) the Company may be more vulnerable to 
downturns in its business or in the general economy and may be restricted 
from making acquisitions, introducing new technologies and products or 
exploiting business opportunities; and (v) the Senior Credit Facilities and 
the Indentures 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. Failure by the Company 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 the Company. In addition, the degree 
to which the Company is leveraged could prevent it from repurchasing all 
Notes tendered to it upon the occurrence of a Change in Control, which would 
constitute an Event of Default under the Indenture. See "Description of the 
Notes" and "Description of Certain Indebtedness". 

ACQUISITION STRATEGY 

   The Company's strategy includes pursuing additional acquisitions that will 
complement its business. There can be no assurance, however, that the Company 
will be able to identify additional acquisition 

                                       11
<PAGE>
candidates on commercially reasonable terms or at all or that, if 
consummated, any anticipated benefits will be realized from such future 
acquisitions. In addition, the availability of additional acquisition 
financing cannot be assured and, depending on the terms of such additional 
acquisitions, could be restricted by the terms of the Senior Credit 
Facilities and/or the Indentures. 

   The process of integrating acquired operations, including the 1998 
Acquisitions, into the Company's existing operations may result in unforeseen 
operating difficulties and may require significant financial and managerial 
resources that would otherwise be available for the ongoing development or 
expansion of the Company's existing operations. Possible future acquisitions 
by the Company 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 the 
Company's financial condition and operating results. 

SIGNIFICANT CUSTOMERS 

   The Company's sales are predominantly derived from contracts with agencies 
of, and prime contractors to, the Government. Although DoD procurement 
spending has declined from the mid-1980s resulting in delays for some new 
program starts, program stretch-outs and program cancellations, the U.S. 
defense budget began to stabilize in fiscal 1996. In 1997, the Company 
performed under approximately 150 contracts with value exceeding $1.0 million 
for the Government. Pro forma sales in 1997 to the Government, including pro 
forma sales to the Government through prime contractors, were $651.1 million, 
representing approximately 73% of the Company's corresponding sales. The 
Company's largest Government program, a cost plus, sole source contract for 
support of the U-2 Program of the DoD, contributed 13% of pro forma sales for 
1997. No other program represented more than 7% of the Company's pro forma 
sales in 1997. The loss of all or a substantial portion of sales to the 
Government would have a material adverse effect on the Company's income and 
cash flow. See "Management's Discussion and Analysis of Financial Condition 
and Results of Operations" and "Business -- Government Contracts". 

   Pro forma sales by the Company to Lockheed Martin were $81.6 million in 
1997 or 9.1% of the Company's total pro forma sales. The loss of all or a 
substantial portion of such sales to Lockheed Martin would have a material 
adverse effect on the Company's income and cash flow. 

RISKS INHERENT IN GOVERNMENT CONTRACTS 

   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. 
The Company's businesses taken as a whole experienced a substantial decline 
in sales during such period. A significant decline in U.S. military 
expenditures in the future could materially adversely affect the Company's 
sales and earnings. The loss or significant curtailment of a material program 
in which the Company participates could also materially adversely affect the 
Company's future sales and earnings and thus the Company's ability to meet 
its 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, among other things, 
the ability of the Government to: (i) suspend unilaterally the Company from 
receiving new contracts pending resolution of alleged violations of 
procurement laws or regulations, (ii) terminate existing contracts, (iii) 
audit the Company's contract-related costs and fees, including allocated 
indirect costs, and (iv) control and potentially prohibit the export of the 
Company's products. 

   All of the Company's Government contracts are, by their terms, subject to 
termination by the Government either for its convenience or for default of 
the contractor. Termination for convenience provisions provide only for the 
recovery by the Company 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 Government in procuring undelivered items from another source. In 
addition to the right of the Government to terminate, Government contracts 
are conditioned upon the continuing availability of Congressional 
appropriations. Congress usually 

                                       12
<PAGE>
appropriates funds for a given program on a fiscal-year basis even though 
contract performance may take more than one year. Consequently, at the outset 
of a major program, the contract is usually partially funded, and additional 
monies are normally committed to the contract by the procuring agency only 
if, as and when appropriations are made by Congress for future fiscal years. 
Foreign defense contracts generally contain comparable provisions relating to 
termination at the convenience of the government. 

   The Company is subject to audit and review by the Government of its costs 
and performance on, and accounting and general business practices relating 
to, Government contracts. The Company's contract related costs and fees, 
including allocated indirect costs, are subject to adjustment based on the 
results of such audits. In addition, under Government purchasing regulations, 
certain of the Company's costs, including certain financing costs, goodwill, 
portions of research and development costs, and certain marketing expenses 
may not be reimbursable under Government contracts. Further, as a government 
contractor, the Company is also subject to investigation, legal action and/or 
liability that would not apply to a commercial company. 

   The Company is subject to risks associated with the frequent need to bid 
on programs in advance of design completion (which may result in unforeseen 
technological difficulties and/or cost overruns), the substantial time and 
effort required for relatively unproductive design and development, design 
complexity and rapid obsolescence, and the constant necessity for design 
improvement. The Company obtains many of its Government contracts through a 
process of competitive bidding. There can be no assurance that the Company 
will continue to be successful in winning competitively awarded contracts or 
that awarded contracts will generate sufficient sales to result in 
profitability for the Company. See "Business -- Major Customers" and 
"--Government Contracts". 

   In addition to these Government contract risks, many of the Company's 
products and systems require licenses from Government agencies for export 
from the United States, and certain of the Company's products currently are 
not permitted to be exported. There can be no assurance that the Company will 
be able to gain any and all licenses required to export its products, and 
failure to receive the required licenses could materially reduce the 
Company's ability to sell its products outside the United States. 

RISKS ASSOCIATED WITH FIXED PRICE CONTRACTS 

   The Company's products and services are provided primarily through fixed 
price or cost plus contracts. Approximately 64% of the Company's pro forma 
sales in 1997 were attributable to fixed price contracts. The financial 
results of long-term fixed price contracts are recognized using the 
cost-to-cost percentage-of-completion method. As a result, revisions in 
revenues and profit estimates are reflected in the period in which the 
conditions that require such revisions become known and are estimable. The 
risks inherent in 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 potential for 
component 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 the Company's 
profitability or cause a loss. Although the Company believes that adequate 
provisions for losses for its fixed price contracts are reflected in its 
financial statements, no assurance can be given that these provisions are 
adequate or that losses on fixed price and time-and-material contracts will 
not occur in the future. 

TECHNOLOGICAL CHANGE; NEW PRODUCT DEVELOPMENT 

   The communication equipment industry for defense applications and in 
general is characterized by changing technology. The Company's ability to 
compete successfully in this market will depend on its ability to design, 
develop, manufacture, assemble, test, market and support new products and 
enhancements on a timely and cost-effective basis. The Company has 
historically obtained technology from substantial customer-sponsored research 
and development as well as from internally funded research and development; 
however, there can be no assurance that the Company will continue to maintain 
comparable levels of customer-sponsored research and development in the 
future. See "Business -- Research and Development". Substantial funds have 
been allocated to capital expenditures and programs and other 

                                       13
<PAGE>
discretionary investments in the past and will continue to be required in the 
future. See "Management's Discussion and Analysis of Financial Condition and 
Results of Operations". There can be no assurance that the Company will 
successfully identify new opportunities and continue to have financial 
resources to develop new products in a timely or cost-effective manner, or 
that products and technologies developed by others will not render the 
Company's products and systems obsolete or non-competitive. 

ENTRY INTO COMMERCIAL BUSINESS 

   The Company's revenues historically have been derived principally from 
business with the DoD and other government agencies. In addition to 
continuing to pursue this major market area, the Company intends to pursue a 
strategy that leverages its technical capabilities and expertise into related 
commercial markets. Certain of the Company's commercial products, such as 
local wireless loop telecommunications equipment, medical image archiving 
equipment and airport security equipment, have only been recently introduced 
or are in the early stages of development. As such, these new products are 
subject to certain risks, including the need to develop and maintain 
marketing, sales and customer support capabilities, to secure third-party 
manufacturing and distribution arrangements, to obtain certification, to 
respond to rapid technological advances and, ultimately, to customer 
acceptance of these products and product performance. The Company's efforts 
to expand its presence in the commercial market will require significant 
resources including capital and management time. There can be no assurance 
that the Company will be successful in addressing these risks or in 
developing these commercial business opportunities. 

COMPETITION 

   The communications equipment industry for defense applications and as a 
whole is highly competitive. Declining defense budgets and increasing 
pressures for cost reductions have precipitated a major consolidation in the 
defense industry. The DoD's increased use of commercial off-the-shelf 
products and components in military equipment is expected to increase the 
entrance of new competitors. In addition, consolidation has resulted in 
delays in contract funding or awards and significant predatory pricing 
pressures associated with increased competition and reduced funding. The 
Company expects that the emergence of merchant suppliers will increase 
competition for OEM business. 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. Many of the 
Company's competitors are larger and have substantially greater financial and 
other resources than the Company. See "Business -- Competition". 

LIMITED OPERATING HISTORY 

   Prior to the L-3 Acquisition, the Company's operations were conducted as 
divisions of Lockheed Martin, Loral, Unisys Corp. ("Unisys") and GE 
Aerospace. Following the L-3 Acquisition in April 1997, the Company has 
operated independently of Lockheed Martin and has provided many corporate 
services on a stand-alone basis that were previously provided by Lockheed 
Martin, including research and development, marketing, and general and 
administrative services including tax, treasury, management information 
systems, human resources and legal services. Lockheed Martin currently 
provides certain management information systems services to certain divisions 
of the Company. There can be no assurance that the actual corporate services 
costs incurred in operating the Company will not exceed historical charges or 
that the Company will be able to obtain similar services on comparable terms. 

DEPENDENCE ON KEY PERSONNEL 

   The Company's success depends to a significant degree upon the continued 
contributions of the Company's management, including Messrs. Lanza and 
LaPenta, and its ability to attract and retain other 


                                       14
<PAGE>
highly qualified management and technical personnel. Messrs. Lanza and 
LaPenta invested approximately $18 million to purchase 16.6% of the initial 
capital stock of Holdings. Holdings has entered into employment agreements 
with Messrs. Lanza and LaPenta. See "Management -- Employment Agreements". 
The Company also faces competition for management and technical personnel 
from other companies and organizations. There can be no assurance that the 
Company will continue to be successful in hiring and retaining key personnel. 
See "Management -- Directors and Executive Officers". 

ENVIRONMENTAL LIABILITIES 

   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 applicable environmental laws and permits. The Company 
does not believe that its environmental compliance expenditures will have a 
material adverse effect on its financial condition or the results of its 
operations. 

   In connection with the L-3 Acquisition, the Company has agreed to assume 
certain on-site and off-site environmental liabilities related to events or 
activities occurring prior to the L-3 Acquisition. Lockheed Martin has agreed 
to retain all environmental liabilities for all facilities no longer used by 
the Businesses and to indemnify fully the Company for such prior site 
environmental liabilities. Lockheed Martin has also agreed, for the first 
eight years following April 1997, to pay 50% of all costs incurred by the 
Company above those reserved for on the Company's balance sheet at April 1997 
relating to certain Company-assumed environmental liabilities and, for the 
seven years thereafter, to pay 40% of certain reasonable operation and 
maintenance costs relating to any environmental remediation projects 
undertaken in the first eight years. The Company is aware of environmental 
contamination at two of the facilities acquired from Lockheed Martin that 
will require ongoing remediation. In November 1997, the Company sold one such 
facility located in Sarasota, Florida, while retaining a leasehold interest 
in a portion of that facility, to Dames & Moore/Brookhill LLC ("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. 

BACKLOG 

   The Company's backlog represents orders under contracts which are 
primarily with the Government. The Government enjoys broad rights to modify 
unilaterally or terminate such contracts. Accordingly, most of the Company's 
backlog is subject to modification and termination at the Government's will. 
There can be no assurance that the Company's backlog will become revenues in 
any particular period or at all. Further, there can be no assurance that the 
margins on any contract included in backlog that does become revenue will be 
profitable. 

OWNERSHIP OF HOLDINGS AND L-3 COMMUNICATIONS 

   After giving effect to the Common Stock Offering, the Lehman Partnership 
will own 37.9% of the outstanding voting stock of Holdings (or 36.6% if the 
Underwriters' over-allotment option is exercised in full), which owns all of 
the outstanding common stock of L-3 Communications. By virtue of such 
ownership, the Lehman Partnership will have the power to influence 
significantly the business and the affairs of Holdings and L-3 Communications 
because of its significant voting power with respect to actions requiring 
stockholder approval. The concentration in ownership of Holdings may preclude 
Holdings from being acquired in a transaction not supported by Holdings' 
principal stockholders, may render more difficult or discourage a proposed 
merger or tender offer, may preclude a successful proxy contest or may 
otherwise have an adverse effect on the market price of the Notes. See 
"Ownership of Capital Stock".

PENSION PLAN LIABILITIES 

   Pursuant to the L-3 Acquisition Agreement, Holdings and L-3 Communications 
assumed certain liabilities relating to defined benefit pension plans for 
present and former employees and retirees of certain businesses which were 
transferred from Lockheed Martin to Holdings and L-3 Communications. Prior to 
the consummation of the L-3 Acquisition, Lockheed Martin received a letter 
from the Pension Benefit Guaranty Corporation (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 resulted in a larger 
liability for accrued benefits than the assumptions used for financial 
reporting under Statement of Financial Accounting Standards Board No. 87, 
"Accounting for Pension Costs" ("FASB 87")). The PBGC underfunding is related 
to the Communication Systems--West, Aviation Recorders and Hycor pension 
plans (collectively, the "Subject Plans"). As of December 31, 1997, the 
Company calculated the net funding position of the Subject Plans and believes 
them to be overfunded by approximately $5.9 million under the Employee 
Retirement Income Security Act of 1974, as amended ("ERISA"), assumptions, 
underfunded by approximately $10.2 million under FASB 87 assumptions and, on 
a termination basis, underfunded by as much as $57.5 million under PBGC 
assumptions. 

   L-3 Communications, Lockheed Martin and the PBGC entered into certain 
agreements dated as of April 30, 1997 that include Lockheed Martin providing 
a commitment to the PBGC with regard to the Subject Plans and L-3 
Communications providing certain assurances to Lockheed Martin regarding such 
plans. See "Business -- Pension Plans". 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 Subject Plans would not be material. However, there can be no assurance 
that the impact of any increased pension expenses or funding requirements 
under this arrangement would not be material to the Company. 

SUBORDINATION 

   Obligations of L-3 Communications and the Guarantors under the Notes and 
the Guarantees, respectively, are subordinate and junior in right of payment 
to all existing and future Senior Debt of L-3 Communications and the 
Guarantors, respectively. As of March 31, 1998, on a pro forma basis after 
giving effect to the L-3 Acquisition, the 1998 Acquisitions and the 
Offerings, L-3 Communications would have had approximately $441.2 million of 
indebtedness outstanding, of which $34.9 million would have been Senior Debt 
(excluding letters of credit) all of which would have been guaranteed by the 
Guarantors on a senior basis. Additional Senior Debt may be incurred by L-3 
Communications from time to time, subject to certain restrictions. By reason 
of such subordination, in the event of an insolvency, liquidation, or other 
reorganization of L-3 Communications or the Guarantors, the lenders under the 
Senior Credit Facilities and other creditors who are holders of Senior Debt 
must be paid in full before the holders of the Notes and the Guarantees may 
be paid; accordingly, there may be insufficient assets remaining after 
payment of prior claims to pay amounts due on the Notes or the Guarantees. In 
addition, under certain circumstances, no payments may be made with respect 
to the Notes or the Guarantees if a default exists with respect to certain 
Senior Debt. The Notes and the Guarantees rank on a parity or pari passu with 
the L-3 Communications' 10 3/8% Senior Subordinated Notes due 2007 and the 
guarantees thereof. See "Description of the Notes -- Subordination". 

RESTRICTIONS IMPOSED BY THE SENIOR CREDIT FACILITIES AND THE INDENTURES 

   The Senior Credit Facilities and the Indentures contain a number of 
significant covenants that, among other things, restrict the ability of L-3 
Communications to dispose of assets, incur additional indebtedness, repay 
other indebtedness, pay dividends, make certain investments or acquisitions, 
repurchase or redeem capital stock, engage in mergers or consolidations, or 
engage in certain transactions with subsidiaries and affiliates and otherwise 
restrict corporate activities. There can be no assurance that such 
restrictions will not adversely affect the Company's ability to finance its 
future operations or capital needs or engage in other business activities 
that may be in the interest of the Company. In addition, the Senior Credit 
Facilities also require L-3 Communications to maintain compliance with 
certain financial 

                                       16
<PAGE>
ratios, including total EBITDA to total interest expense and total debt to 
total EBITDA, and limit capital expenditures by L-3 Communications. The 
ability of L-3 Communications to comply with such ratios and limits may be 
affected by events beyond L-3 Communications' control. A breach of any of 
these covenants or the inability of L-3 Communications to comply with the 
required financial ratios or limits could result in a default under the 
Senior Credit Facilities. In the event of any such default, the lenders under 
the Senior Credit Facilities could elect to declare all borrowings 
outstanding under the Senior Credit Facilities, together with accrued 
interest and other fees, to be due and payable, to require L-3 Communications 
to apply all of its available cash to repay such borrowings or to prevent L-3 
Communications from making debt service payments on other indebtedness 
(including the 1997 Notes), any of which would be an Event of Default under 
the Notes. If L-3 Communications were unable to repay any such borrowings 
when due, the lenders could proceed against their collateral. In connection 
with the Senior Credit Facilities, L-3 Communications has granted the lenders 
thereunder a first priority lien on substantially all of its assets. The 
lenders under the Senior Credit Facilities will also have a first priority 
security interest in all of the capital stock of L-3 Communications and its 
subsidiaries. If the indebtedness under the Senior Credit Facilities, the 
1997 Notes or the Notes were to be accelerated, there can be no assurance 
that the assets of L-3 Communications would be sufficient to repay such 
indebtedness in full. See "Description of the Notes" and "Description of 
Certain Indebtedness". 

FRAUDULENT CONVEYANCE 

   A portion of the indebtedness under the Notes and the Guarantees is being 
incurred to repay the interim financing for the 1998 Acquisitions and to 
repay the indebtedness incurred under the Senior Credit Facilities in 
connection with the L-3 Acquisition. Management believes that the 
indebtedness of L-3 Communications represented by the Notes and the 
indebtedness of the Guarantors represented by the Guarantees is being 
incurred for proper purposes and in good faith, and that, based on present 
forecasts and other financial information, after the issuance of the Notes 
and the Guarantees, L-3 Communications and the Guarantors will be solvent, 
will have sufficient capital for carrying on its business and will be able to 
pay its debts as they mature. Notwithstanding management's belief, however, 
under federal and state fraudulent transfer laws, if a court of competent 
jurisdiction in a suit by an unpaid creditor or a representative of creditors 
(such as a trustee in bankruptcy or a debtor-in-possession) were to find 
that, at the time of the incurrence of such indebtedness, any of L-3 
Communications and the Guarantors was insolvent, was rendered insolvent by 
reason of such incurrence, was engaged in a business or transaction for which 
its remaining assets constituted unreasonably small capital, intended to 
incur, or believed that it would incur, debts beyond its ability to pay such 
debts as they matured, or intended to hinder, delay or defraud its creditors, 
and that the indebtedness was incurred for less than reasonably equivalent 
value, then such court could, among other things, (i) void all or a portion 
of L-3 Communications' obligations to the Holders of the Notes or the 
Guarantors' obligations under the Guarantees, the effect of which would be 
that the Holders of the Notes and the Guarantees might not be repaid in full 
and/or (ii) subordinate obligations of L-3 Communications or the Guarantors 
to the Holders of the Notes and the Guarantees to other existing and future 
indebtedness of L-3 Communications or the Guarantors, as the case may be, to 
a greater extent than would otherwise be the case, the effect of which would 
be to entitle such other creditors to which the Notes and the Guarantees were 
not previously subordinated to be paid in full before any payment could be 
made on the Notes and the Guarantees. See "--Substantial Leverage" above. 

LIMITATION ON CHANGE OF CONTROL 

   The Indentures provide that, upon the occurrence of a Change of Control of 
L-3 Communications or Holdings, L-3 Communications will make an offer to 
purchase all of the Notes and the 1997 Notes at a price in cash equal to 101% 
of the aggregate principal amount thereof together with accrued and unpaid 
interest to the date of purchase. The Senior Credit Facilities currently 
prohibit L-3 Communications from repurchasing any Notes or 1997 Notes except 
with the proceeds of one or more Equity Offerings. The Senior Credit 
Facilities also provide that certain change of control events with respect to 
the Company would constitute a default thereunder. Any future credit 
agreements or other agreements relating to Senior Debt to which L-3 
Communications becomes a party may contain similar restrictions and 

                                       17
<PAGE>
provisions. In the event a Change of Control event occurs at a time when L-3 
Communications is prohibited from purchasing the Notes or the 1997 Notes, or 
if L-3 Communications is required to make a Net Proceeds Offer (as defined 
under "Description of the Notes") pursuant to the terms of the Notes or the 
1997 Notes, L-3 Communications could seek the consent of its lenders to the 
purchase of the Notes or the 1997 Notes or could attempt to refinance the 
borrowings that contain such prohibition. If L-3 Communications does not 
obtain such a consent or repay such borrowings, L-3 Communications will 
remain prohibited from purchasing the Notes or the 1997 Notes. In such case, 
L-3 Communications' failure to make such an offer or to purchase tendered 
Notes or the 1997 Notes would constitute an Event of Default under the 
Indenture or the 1997 Indenture. If, as a result thereof, a default occurs 
with respect to any Senior Debt, the subordination provisions in the 
Indenture would likely restrict payments to the holders of the Notes. 
Finally, L-3 Communications' ability to pay cash to the holders of Notes or 
the 1997 Notes upon a purchase may be limited by L-3 Communications' 
then-existing financial resources. There can be no assurance that sufficient 
funds will be available when necessary to make any required purchases. 
Furthermore, the Change of Control provisions may in certain circumstances 
make more difficult or discourage a takeover of the Company. See "Description 
of the Notes --Repurchase at the Option of Holders -- Change of Control". 

LACK OF MARKET FOR THE NOTES 

   There is no existing trading market for the Notes, and there can be no 
assurance regarding the future development of a market for the Notes or the 
ability of the Holders of the Notes to sell their Notes or the price at which 
such Holders may be able to sell their Notes. If such market were to develop, 
the Notes could trade at prices that may be higher or lower than their 
initial offering price depending on many factors, including prevailing 
interest rates, the Company's operating results and the market for similar 
securities. The Underwriters have advised the Company that they currently 
intend to make a market with respect to the Notes. However, the Underwriters 
are not obligated to do so, and any market making with respect to the Notes 
may be discontinued at any time without notice. Because Lehman Brothers Inc. 
is an affiliate of the Company, Lehman Brothers Inc. will be required to 
deliver a current "market-maker" prospectus and otherwise comply with the 
registration requirements of the Securities Act in connection with any 
secondary market sale of the Notes, which may affect its ability to continue 
market-making activities. See "Underwriting". No assurance can be given as to 
the liquidity of or the trading market for the Notes. 

FORWARD LOOKING STATEMENTS 

   This Prospectus contains forward looking statements concerning the 
Company's operations, economic performance and financial condition, including 
in particular, the likelihood of the Company's success in developing and 
expanding its business and the realization of sales from backlog. These 
statements are based upon a number of assumptions and estimates which are 
inherently subject to significant uncertainties and contingencies, many of 
which are beyond the control of the Company, and reflect future business 
decisions which are subject to change. Some of these assumptions inevitably 
will not materialize, and unanticipated events will occur which will affect 
the Company's future results. All such forward looking statements are 
qualified by reference to matters discussed under this section entitled "Risk 
Factors".

                               USE OF PROCEEDS 

   The net proceeds to the Company from the Notes Offering, are estimated to 
be approximately $173.7 million, after deducting underwriting discounts, 
commissions and estimated offering expenses. 

   The Company intends to use the net proceeds of the Notes Offering, 
together with the net proceeds of the Common Stock Offering contributed to 
L-3 Communications, to repay a substantial portion of its existing 
indebtedness under the Senior Credit Facilities and for general corporate 
purposes, including potential acquisitions. The borrowings under the Senior 
Credit Facilities had been used by the Company to fund in part the L-3 
Acquisition and the 1998 Acquisitions. The weighted average interest rate 
under the Term Loan Facilities was 7.91% at April 15, 1998. Amounts repaid 
under the Revolving Credit Facility 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. Affiliates of the Underwriters 
are lenders under the Senior Credit Facilities and will receive a portion of 
the net proceeds of the Offerings in repayment of amounts outstanding 
thereunder. See "Description of Certain Indebtedness -- Senior Credit 
Facilities".

       UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION 

   The following unaudited pro forma financial information gives effect to 
the L-3 Acquisition, the 1998 Acquisitions and the Offerings (collectively, 
the "Transactions"). The Offerings include the Notes Offering and the 
contribution by Holdings to the Company of the proceeds of the Common Stock 
Offering. The pro forma financial information is based on (i) the unaudited 
condensed consolidated financial statements of the Company for the 
three-month period ended March 31, 1998, (ii) the consolidated financial 
statements of the Company for the nine-month period ended December 31, 1997, 
(iii) the Combined Statement of Operations of the Predecessor Company for the 
three-month period ended March 31, 1997 and (iv) the financial statements of 
the 1998 Acquisitions for the year ended December 31, 1997, 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 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 consolidated financial 
statements of the Company for the three-month period ended March 31, 1998, 
(ii) 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, (iii) the 
audited financial statements of STS for the year ended June 30, 1997, (iv) 
the unaudited condensed financial statements of STS as of December 31, 1997 
and for the six months ended December 31, 1997 and 1996, (v) the audited 
consolidated financial statements of ILEX as of December 31, 1997 and for the 
year ended December 31, 1997 and (vi) the audited combined financial 
statements of Ocean Systems as of December 31, 1997 and for the year ended 
December 31, 1997, all of which are included elsewhere herein. 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 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 three months ended March 31, 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 effective cost of borrowing rates 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 for the nine 
   months ended December 31, 1997 which is 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 February 5, 1998, L-3 Communications purchased the assets of STS for 
   $27.0 million of cash. On March 4, 1998, L-3 Communications purchased 
   substantially all the assets of ILEX for $49.2 million of cash (net of 
   acquired cash of $2.7 million) plus additional consideration contingent 
   upon post-acquisition performance of ILEX. On March 30, 1998, L-3 
   Communications purchased the assets of Ocean Systems for $67.5 million of 
   cash. The purchase prices are subject to adjustment based upon the actual 
   closing net assets of STS and ILEX as defined. For purposes of the pro 
   forma financial information, the aggregate purchase prices (including 
   estimated expenses of $2.6 million) for the 1998 Acquisitions of $146.3 
   million were assumed to be financed using cash on hand of $77.5 million 
   and initially using $68.8 million of borrowings under the Revolving Credit 
   Facility. See Note 5 for the pro forma effects of the Offerings on 
   interest expense and long-term debt including the Revolving Credit 
   Facility.

4. The aggregate estimated excess of purchase price over fair value of net 
   assets acquired related to the 1998 Acquisitions is $89.0 million, 
   comprised of $37.2 million and $51.8 million, respectively, for ILEX and 
   Ocean Systems and is being amortized over 40 years resulting in a pro 
   forma charge of $2.2 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 net assets acquired. 

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

 (1)   Reflects the L-3 Acquisition effective April 1, 1997. 
 (2)   Reflects ownership of Loral's Communication Systems -- West and 
       Specialized Communication Products businesses commencing April 1, 1996. 
 (3)   Reflects ownership of Communication Systems -- East by Lockheed Martin 
       effective April 1, 1993. 
 (4)   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. 
 (5)   Includes a nonrecurring, noncash compensation charge of $4.4 million 
       related to the initial capitalization of the Company, effective April 
       1, 1997. 
 (6)   For periods prior to April 1, 1997, interest expense and income tax 
       (benefit) provision were allocated from Lockheed Martin. 
 (7)   EBITDA is defined as operating income plus depreciation expense and 
       amortization expense (excluding the amortization of deferred debt 
       issuance costs) and the nonrecurring, noncash compensation charge of 
       $4.4 million recorded 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. 
 (8)   For purposes of this computation, earnings consist of income before 
       income taxes plus fixed charges. Fixed charges consist of interest on 
       indebtedness plus that portion of lease rental expense representative 
       of the interest element. 
 (9)   Earnings were insufficient to cover fixed charges by $0.5 million for 
       the three months ended March 31, 1997. 
(10)   Pro forma earnings would have been insufficient to cover pro forma 
       fixed charges by $0.2 million for the three months ended March 31, 
       1998. 
(11)   For purposes of this computation, cash interest expense consists of pro 
       forma interest expense excluding amortization of deferred debt issuance 
       costs. 
(12)   These ratios as of and for the three months ended March 31, 1998 are 
       based on the results of operations for the twelve month period ended 
       March 31, 1998. The pro forma ratios have been calculated by adding the 
       pro forma EBITDA and cash interest expense for the year ended December 
       31, 1997 and the three months ended March 31, 1998 and deducting the 
       pro forma EBITDA and cash interest expense for the three months ended 
       March 31, 1997. For purposes of computing pro forma EBITDA for the 
       three months ended March 31, 1997, depreciation expense and 
       amortization expense were $6.0 million and $2.7 million, respectively. 
       The historical ratios have been calculated by adding historical EBITDA 
       and cash interest expense for the nine months ended December 31, 1997 
       and the three months ended March 31, 1998. 
(13)   Net debt is defined as long-term debt plus current portion of long-term 
       debt less cash and cash equivalents.

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

   The matters discussed herein may include "forward-looking statements" as 
defined in the Private Securities Litigation Reform Act of 1995. Such 
statements involve risks and uncertainties which could result in operating 
performance that is materially different from management's projections. The 
section of this Prospectus entitled "Risk Factors" should be read in 
conjunction with this Management's Discussion and Analysis of Financial 
Condition and Results of Operations section. 

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 DoD, selected Government intelligence agencies, major 
aerospace/defense prime contractors, foreign governments and commercial 
customers. The Company operates primarily in one industry segment, electronic 
components and systems. 

   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 recently 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 digital command and control communications 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. According to Federal Sources, an independent private 
consulting group, the defense budget for C(3)I is expected to increase from 
$31.0 billion in the fiscal year ended September 30, 1997 to $42.0 billion in 
the fiscal year ended September 30, 2002, a compound annual growth rate of 
6.3%. 

 ACQUISITION HISTORY 

   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 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". 

   The Company acquired the assets and liabilities of Ocean Systems, ILEX and 
STS on March 30, 1998, March 4, 1998 and February 5, 1998, respectively. 


                                       29

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 herein. 

   The financial statements 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 Ocean Systems, ILEX and STS (collectively, the 
"1998 Acquisitions") from the effective dates of such acquisitions, which 
were March 31, 1998 for Ocean Systems, and February 1, 1998 for ILEX and STS. 
The results of operations presented below exclude the results of operations 
of the 1998 Acquisitions for the years ended December 31, 1997, 1996 and 
1995. 

   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 Lockheed Martin. Therefore, the results of operations 
for the year ended December 31, 1996 reflect the results of operations of the 
Loral Acquired Businesses for the nine months from April 1, 1996 to December 
31, 1996. Accordingly, changes between periods for the year ended December 
31, 1997 and the year ended December 31, 1996 of the Predecessor Company are 
significantly affected by the timing of the L-3 Acquisition and Loral 
Acquired Businesses acquisition. 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. 
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, 
in the purchase accounting for 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. 

   As indicated in Note 6 to the Consolidated (Combined) Financial Statements 
as of December 31, 1997, effective April 1, 1997 the Company has accounted 
for the sale of its Hycor business in accordance with FASB Emerging Issues 
Task Force Issue No. 87-11 "Allocation of Purchase Price to Assets to Be 
Sold". Accordingly, the results of operations of the Hycor business are not 
included in the results of operations of the Company for the three months 
ended March 31, 1998 and the nine months ended December 31, 1997. Hycor is a 
business unit of the Loral Acquired Businesses, and, accordingly, Hycor is 
only included in the results of operations of the Predecessor Company 
beginning on April 1, 1996, the effective date of the Loral Acquired 
Businesses acquisition by Lockheed Martin. On January 29, 1998, the Company 
sold the Hycor business, excluding land and buildings, for $3.5 million in 
cash subject to adjustment based on final closing net assets. 

   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.

- ------------ 
(1)    EBITDA is defined as operating income plus depreciation expense and 
       amortization expense (excluding the amortization of debt issuance 
       costs). 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 to $186.6 million for the three months ended March 31, 
1998 (the "1998 First Quarter") from $158.9 million for the three months 
ended March 31, 1997 (the "1997 First Quarter"). Operating income increased 
to $14.1 million in the 1998 First Quarter from $7.9 million in the 1997 
First Quarter. Net income increased to $2.6 million in the 1998 First Quarter 
from a net loss of $0.3 million in the 1997 First Quarter. 

   ILEX and STS contributed sales of $16.9 million to the 1998 First Quarter. 
The remaining increase of $10.8 million was primarily attributable to an 
increase in production and shipments on the CHBDL and UAV programs and 
increased sales volumes on the E2-C and F-14 display systems and RF safety 
products, partially offset by lower sales volume on the U-2 Program. 

   Operating income increased by $6.2 million to $14.1 million in the 1998 
First Quarter from $7.9 million in the 1997 First Quarter. Operating income 
as a percentage of sales increased to 7.6% for the 1998 First Quarter 
compared to 5.0% for the 1997 First Quarter. The increase in operating 
margins for the 1998 First Quarter is attributable to improved operating 
performance on sales of aviation recorders and display systems and increased 
sales volume on the CHBDL program and RF safety products, partially offset by 
lower sales volume on the U-2 Program. Also, the 1997 First Quarter operating 
income was negatively impacted by losses incurred on three programs by 
Communication Systems --East. ILEX and STS contributed $0.3 million of 
operating income to the 1998 First Quarter. 

   EBITDA for the 1998 First Quarter increased by $5.9 million to $21.6 
million from $15.7 million in the 1997 First Quarter. EBITDA as a percentage 
of sales ("EBITDA margin") increased to 11.6% for the 1998 First Quarter 
compared to 9.9% for the 1997 First Quarter. The increases in EBITDA and 
EBITDA margin were attributable to the items affecting the trends in 
operating income between the 1998 First Quarter and the 1997 First Quarter 
discussed above. 

   Sales and operating income of the Hycor business included in the 
Predecessor Company's results of operations for the 1997 First Quarter were 
$1.8 million and $0.0 million, respectively. 

   Net interest expense for the 1998 First Quarter was $9.8 million 
representing interest expense on the Company's borrowings under the Senior 
Credit Facilities and the 10 3/8% senior subordinated notes, and related 
amortization of debt issuance cost, less interest income of $0.8 million. 
Interest expense for the 1997 First Quarter of $8.4 million 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 income tax provision for the 1998 First Quarter reflects the Company's 
estimated effective income tax rate of 39%. In the 1997 First Quarter, income 
taxes were allocated to the Predecessor Company by 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.

</TABLE>

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

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

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

   Sales and operating income of the Hycor business included in the 
Predecessor Company's results of operations 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. 

   Net interest expense 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 and interest expense of $0.6 million allocated to the Hycor 
business net assets held for sale. 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 



                                       32
<PAGE>
interest expense reflects higher interest rates on the 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 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 (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 (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.

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

   Sales for the 1997 period increased to $705.4 million from $675.3 million 
for the 1996 period. Operating income increased to $63.1 million in the 1997 
period from $51.5 million in the 1996 period. 

                                       33
<PAGE>
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 income as a 
percentage of sales increased to 8.4% in the 1997 period as compared to 7.6% 
in the 1996 period. The increase in operating income was largely attributable 
to cost reductions, increased sales volume of the Loral Acquired Businesses 
and operating improvements at Communications Systems -- East. Operating 
income for the 1997 period also included (i) a nonrecurring, noncash 
compensation charge of $4.4 million recorded effective April 1, 1997, related 
to the initial capitalization of L-3 and (ii) fourth quarter cost of sales of 
$3.3 million related to on-going certification efforts for the Company's EDS 
contract. Excluding the noncash compensation charge and these EDS costs, 
operating income would have been $67.1 million for the 1997 period and 
operating income as a percentage of sales would have been 9.5%. 

   EBITDA for the 1997 period increased by $9.2 million to $93.8 million from 
$84.6 million from 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. 


                                       34
<PAGE>
   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. As a percentage of sales, operating income 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 

 THE L-3 ACQUISITION 

   Effective April 1, 1997, the Company purchased the Businesses from 
Lockheed Martin for $503.8 million, after a purchase price adjustment of 
$21.2 million and acquisition costs of $8.0 million. On November 5, 1997 the 
L-3 Acquisition Agreement was amended to finalize the purchase price 
adjustment which amounted to $21.2 million of which $15.9 million was 
received on April 30, 1997 and $5.3 million was received on November 7, 1997, 
plus interest thereon. The amendment 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 ("C(2)V") Mission Module Systems 
("MMS"), for which the Company received a cash payment of $12.2 million from 
Lockheed Martin. 

 FINANCING 

   The L-3 Acquisition was funded by a combination of debt and equity 
aggregating $525.0 million. The equity of $125.0 million was comprised of 
$80.0 million in cash contributed to Holdings by the Lehman Partnership and 
Senior Management and a $45.0 million retained interest in Holdings by 
Lockheed Martin representing partial consideration to Lockheed Martin for its 
sale of the Businesses to the Company. In connection with the L-3 
Acquisition, the Company entered into a $275.0 million credit facility 
consisting of $175.0 million of term loans (the "Term Loan Facilities") and a 
$100.0 million revolving credit facility (the "Revolving Credit Facility") 
(collectively, the "Senior Credit Facilities"). The initial debt balance of 
$400.0 million consisted of $175.0 million of borrowings under the Term Loan 
Facilities and $225.0 million of 10 3/8% Senior Subordinated Notes (the "1997 
Notes") due May 1, 2007. 

   The required principal payments under the Term Loans Facilities are: $5.0 
million in 1998, $11.0 million in 1999, $19.0 million in 2000, $25.0 million 
in 2001, $33.2 million in 2002, $20.0 million in 2003, and $25.2 million in 
2004, $24.9 million in 2005, and $8.7 million in 2006. Interest payments on 
the Term Loan Facilities vary in accordance with the type of borrowings and 
are made at a minimum every three months. At December 31, 1997, the Senior 
Credit Facilities also included a $100.0 million Revolving Credit Facility. 
In February 1998, the Senior Credit Facilities were amended to, among other 
things, increase the amount available under the revolving credit facility to 
$200.0 million, waive certain excess cash flow prepayments, as defined, 
otherwise required, and permit the incurrence of up to an additional $150.0 
million of subordinated debt. Other than upon a change of control or the 
occurrence of certain asset sales, L-3 Communications will not be required to 
repurchase the 1997 Notes until maturity on May 1, 2007. L-3 Communications 
is required to make semi-annual interest payments with respect to the 1997 
Notes. 

   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 

                                       35
<PAGE>
under the Revolving Credit Facility, 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, or make necessary capital 
expenditures and program and discretionary investments. 

   On November 5, 1997, L-3 Communications 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 L-3 
Communications, 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, L-3 Communications may 
redeem up to 35% of the aggregate principal amount of the 1997 Notes at a 
redemption price of 109.375% of the principal amount thereof, plus accrued 
and unpaid interest to the redemption date with the net cash proceeds of one 
or more equity offerings by Holdings that are contributed to L-3 
Communications as common equity capital. See "Risk Factors -- Substantial 
Leverage". 

   The Senior Credit Facilities and the 1997 Notes contain financial 
covenants, which remain in effect so long as any amount is owed thereunder by 
L-3 Communications. The financial covenants under the Senior Credit 
Facilities require that (i) L-3 Communications' 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) L-3 Communications' 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 
ending after June 30, 2002. At December 31, 1997, L-3 Communications was and 
has been in compliance with these covenants at all times. 

   To mitigate risks associated with changing interest rates on certain of 
its debt, the Company entered into the 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 December 31, 1997. See 
Note 10 to the Consolidated (Combined) Financial Statements. 

1998 ACQUISITIONS 

   On March 30, 1998, the Company purchased the assets of Ocean Systems for 
$67.5 million of cash. On March 4, 1998, the Company purchased 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. On February 5, 1998, the Company purchased the assets of STS for $27.0 
million in cash, subject to adjustment based upon closing net assets. 

   The Company financed the 1998 Acquisitions using cash on hand and 
borrowings under the Revolving Credit Facility. 

                                       36
<PAGE>
   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. As of the date hereof, the Company has 
completed, has reached agreement on or is in discussions regarding certain 
acquisitions, in addition to the 1998 Acquisitions, that are either 
individually or in the aggregate not material to the financial condition of 
results of operations of the Company.

</TABLE>

   NET CASH FROM (USED IN) OPERATING ACTIVITIES: Cash provided by operating 
activities of the Company for the three months ended March 31, 1998 was $11.1 
million. Earnings after adjustment for non-cash items provided $12.3 million, 
offset by uses of cash caused by changes in operating assets and liabilities 
of $1.3 million, net of amounts acquired. Increases in contracts in process 
of $21.3 million during the three months ended March 31, 1998 were partially 
offset by increases of $19.8 million primarily in operating liabilities. 

   Net cash used in operating activities of the Predecessor Company was $16.3 
million for the three months ended March 31, 1997, resulting primarily from 
the increase in contracts in process and decrease in current liabilities. 
Cash flows used by the Loral Acquired Businesses was $10.2 million. Cash used 
for operating activities by Communication Systems -- East amounted to $6.1 
million. 

   The Company's current ratio at March 31, 1998 decreased to 1.4:1 compared 
with 2.0:1 at December 31, 1997. 

   NET CASH (USED IN) INVESTING ACTIVITIES: Cash used in investing activities 
for the three months ended March 31, 1998 consisted primarily of $151.4 
million, net of cash acquired of $2.7 million, paid by the Company for 
acquisitions, of which $146.3 million pertained to the 1998 Acquisitions. 
Cash proceeds from assets held for sale was $4.8 million. Cash used for 
capital expenditures was $2.3 million and $4.3 million, respectively, for the 
three months ended March 31, 1998 and the three months ended March 31, 1997. 
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. 

   NET CASH FROM FINANCING ACTIVITIES: For the three months ended March 31, 
1998, the Company's cash from financing activities was $69.2 million, and was 
comprised of borrowings under the Revolving Credit Facility of $67.8 million; 
the contribution from Holdings of the proceeds of $3.0 million from the 
exercise of stock options of Holdings on March 2, 1998 by Mr. Lanza and Mr. 
LaPenta; scheduled debt payments under the Term Loan Facilities of $1.0 
million; and, debt issuance costs of $0.6 million which were incurred in 
connection with the February 1998 amendment to the Senior Credit Facilities. 

   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 financing activities of the Predecessor Company for the three 
months ended March 31, 1997 was $20.6 million, and represent advances from 
Lockheed Martin, the Predecessor Company's parent company.

</TABLE>

   NET CASH FROM (USED IN) OPERATING ACTIVITIES: Cash provided by operating 
activities of the Company for the nine months ended December 31, 1997 was 
$73.9 million. Cash provided by operations benefited from improved operating 
results, effective management of contracts in process and increases in 
accrued employment costs. Contracts in process declined by $18.2 million to 
$167.2 million from April 1, 1997 to December 31, 1997, and was primarily 
attributable to collections of and reductions in the levels of commercial and 
affiliate receivables. 

   Net cash used in operating activities of the Predecessor Company was $16.3 
million for the quarter ended March 31, 1997, resulting primarily from the 
increase in contracts in process and decrease in current liabilities. Cash 
flows used by the Loral Acquired Businesses was 10.2 million. Cash used for 
operating activities by Communication Systems -- East amounted to $6.1 
million. 

   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. 

   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 (USED IN) INVESTING ACTIVITIES:  Cash used in investing 
activities for the nine months ended December 31, 1997 consisted primarily of 
$466.3 million paid by the Company for the L-3 Acquisition (See Note 1 to 
Consolidated (Combined) Financial Statements); offset by proceeds from the 
sale of the Company's Sarasota, Florida property of approximately $9.5 
million and cash received in connection with the assumption of obligations 
under the C(2)V MMS contract from Lockheed Martin of $12.2 million. 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. In addition, for the nine 
months ended December 31, 1997 and the three months ended March 31, 1997, 
$11.9 million and $4.3 million, respectively, was used for capital 
expenditures, and $5.1 million and $0.0 million, respectively, for purchase 
of investments. 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. 

   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 of the Company was $461.4 million for the nine months ended 
December 31, 1997, and was due to the debt incurred and proceeds from the 
issuance of common stock which were issued to finance the L-3 Acquisition. 
See "--Financing" above. Net cash from financing activities also reflects the 
payment of debt issue costs of $15.6 million and $3.0 million of scheduled 
debt payments of the Term Loan Facilities. 


                                       38
<PAGE>
   Prior to the L-3 Acquisition, the Businesses 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 at December 31, 1997 totaled $516.9 million, 
as compared with 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 86.0% of the backlog at 
December 31, 1997 will be recorded as sales during 1998. However, there can 
be no assurance that the Company's backlog will become revenues in any 
particular period, if at all. See "Risk Factors -- Backlog". Approximately 
81% of the total backlog at December 31, 1997 was directly or indirectly for 
defense contracts for end use by the Government. Approximately $434.0 million 
of total backlog was directly or indirectly for U.S. and foreign government 
defense contracts, and approximately $19.5 million of total backlog was 
directly or indirectly for U.S. and foreign government non-defense contracts. 
Foreign customers account for approximately $34.6 million of the total 
backlog. 

RESEARCH AND DEVELOPMENT 

   Research and development, including bid and proposal, costs ("R&D costs") 
sponsored by the Company was $28.9 million for the nine months ended December 
31, 1997. 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 March 31, 1998 and Note 13 to the Consolidated (Combined) 
Financial Statements as of December 31, 1997. 

RECENT ACCOUNTING PRONOUNCEMENTS 

   In June 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 business 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 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 


                                      39
<PAGE>
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 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. 

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 CONVERSION 

   Under the Company's decentralized structure, each division maintains 
and/or outsources its computer-based data processing functions. While each 
division is responsible for its own computer-based functions, in late 1997 a 
corporate-wide Year 2000 program (the "Program") was instituted for purposes 
of overseeing Year 2000 compliance efforts. The Program's major phases 
include (i) identification of areas requiring update, which began in late 
1997; (ii) assessment of required actions and related impacts, which 
commenced in the first quarter of 1998; (iii) development of update schedule 
and cost estimates, which is scheduled to be concluded in the second quarter 
of 1998 and (iv) implementation of such plan, including follow-up testing, 
which is scheduled to commence during the second quarter of 1998 and be 
completed by mid-1999. Through December 31, 1997, the costs incurred in 
connection with the Program were not material. While these cost estimates 
have not been finalized, based upon the type of systems employed by the 
Company, costs of the Program are not expected to be material to the results 
of operations, liquidity or capital resources of the Company.

                                   BUSINESS 

COMPANY OVERVIEW 

   L-3 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, 
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. 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 DoD, 
selected Government intelligence agencies, major aerospace/defense prime 
contractors, foreign governments and commercial customers. In 1997, L-3 had 
pro forma sales of $894.0 million and pro forma EBITDA of $95.1 million. The 
Company's pro forma funded backlog as of December 31, 1997 was $638.1 
million. These results reflect internal growth as well as the execution of 
the Company's strategy of acquiring businesses that complement or extend 
L-3's product lines. 

   The Company's business areas enjoy proprietary technologies and 
capabilities and have leading positions in their respective primary markets. 
Management has organized the Company's operations into two primary business 
areas: Secure Communication Systems and Specialized Communication Products. 
In 1997, the Secure Communication Systems and Specialized Communication 
Products business areas generated approximately $456.0 million and $438.0 
million of pro forma sales, respectively, and $52.3 million and $42.8 million 
of pro forma EBITDA, respectively. In addition, the Company is seeking to 
expand its products and technologies in commercial markets. See " -- Emerging 
Commercial Products" below. 

   SECURE COMMUNICATION SYSTEMS. L-3 is the established leader in secure,

aligned commercial business areas and applications. Emerging Commercial 
Products currently include the following three niche markets: (i) medical 
archiving and simulation systems; (ii) local wireless loop telecommunications 
equipment; and (iii) airport security equipment. These commercial products 
were developed based on technology used in the Company's military businesses 
with relatively small incremental financial investments. The Company is 
applying its technical capabilities in high data rate communications and 
archiving technology developed in its Secure Communication Systems business 
area to the medical image archiving market jointly with GE Medical Systems. 
Based on secure, high data rate communications technology also developed in 
its Secure Communication Systems business area, the Company has 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 non-existent. L-3 has completed 
the development phase for the local wireless loop telecommunications 
equipment and made its initial shipment in January 1998. In addition, the FAA 
has awarded the Company a development contract for next generation airport 
security equipment for explosive detection. L-3 has shipped two prototype 
test units and FAA certification testing commenced in the first quarter of 
1998. To date, revenues generated from L-3's Emerging Commercial Products 
have not been, in the aggregate, material to the Company.

INDUSTRY OVERVIEW 

   The defense industry has recently 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 digital command and control communications 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. According to Federal Sources, an independent private 
consulting group, the defense budget for C(3)I is expected to increase from 
$31.0 billion in the fiscal year ended September 30, 1997 to $42.0 billion in 
the fiscal year ended September 30, 2002, a compound annual growth rate of 
6.3%. 

   The industry has also undergone dramatic consolidation resulting in the 
emergence of three dominant prime system contractors (Boeing, Lockheed Martin 
and 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 businesses by 
AlliedSignal, Ceridian, 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 

   In 1997, management 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 existing 

                                       45
<PAGE>
    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 ASTOR program in the United Kingdom 
    and both prime contractor bids for the DoD's 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 65% of the Company's 
    total pro forma 1997 sales were generated from sole source contracts. 
    L-3's customer satisfaction and excellent performance record are evidenced 
    by its performance-based award fees exceeding 90% 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 (excluding the 
    1998 Acquisitions) has experienced a contract award win rate in 1997 in 
    excess of 60% 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 and facilities expenses, 
    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. Over 
    the past three years, 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 2,000 
    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 13% of 1997 pro forma sales, is a long-term, sole 
    source, cost plus contract for the U-2 Program. No other program 
    represented more than 7% of 1997 sales on a pro forma basis, assuming the 
    L-3 Acquisition had occurred on January 1, 1997. Further, the Company's 
    pro forma sales mix of contracts in 1997 was 36% cost plus and 64% 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 

                                       46
<PAGE>
    attractive customer mix of defense and commercial business, with DoD 
    related sales accounting for 62% and commercial and federal (non-DoD) 
    sales accounting for 38% of 1997 pro forma sales. 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, 
    a number of merchant companies were sold: Computing Devices International 
    division of Ceridian to General Dynamics, Kaman Sciences to ITT, BDM to 
    TRW and TASC Inc., a subsidiary of Primark Corporation, to Litton. 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.

                                       48
<PAGE>
   During the 1980s, largely based on its prior experience with command and 
control guidance systems for remotely-piloted vehicles, L-3 developed its 
current family of strategic and tactical data links, including its Modular 
Interoperable Data Link ("MIDL") systems and Modular Interoperable Surface 
Terminals ("MIST"). MIDL and MIST technologies are considered virtual DoD 
standards in terms of data link hardware. The Company's primary focus is 
spread spectrum communication (based on CDMA technology), which involves 
transmitting a data signal with a high rate noise signal so as to make it 
difficult to detect by others, and then re-capturing the signal and removing 
the noise. The Company's data links are capable of providing information at 
over 200 Mb/s. 

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

o SATELLITE COMMUNICATION TERMINALS 

   L-3 provides ground-to-satellite, high availability, real-time global 
communications capability through a family of transportable field terminals 
to communicate with commercial, military and international satellites. These 
terminals provide remote personnel with anywhere, anytime effective 
communication capability and provide communications links to distant forces. 
The Company's TriBand SATCOM Subsystem ("TSS") employs a 6.25 meter tactical 
dish with a single point feed that provides C, Ku and X band communication to 
support the U.S. Army. The Company also offers an 11.3 meter dish which is 
transportable on two C-130 aircraft. The SHF Portable Terminal System ("PTS") 
is a lightweight (28 lbs.), manportable terminal, which communicates through 
DSCS, NATO or SKYNET satellites and brings unprecedented connectivity to 
small military tactical units and mobile command posts. L-3 delivered 14 of 
these terminals for use by NATO forces in Bosnia. 

o SPACE COMMUNICATIONS AND SATELLITE CONTROL 

   Continuing L-3's tradition of providing communications for every manned 
U.S. space flight since Mercury, the Company is currently designing and 
testing three communication subsystems for the International Space Station 
("ISS"). These systems will control all ISS radio frequency ("RF") 
communications and external video activities. The Company also provides 
solid-state recorders and memory units for data capture, storage, transfer 
and retrieval for space applications. The standard NASA tape recorder, which 
was developed and produced by the Company, has completed over four million 
hours of service without a mission failure. Current programs include 
recorders for the National Oceanic & Atmospheric Administration ("NOAA") 
weather satellites, the Earth Observing Satellite ("EOS"), AM spacecraft and 
Landsat-7 Earth-monitoring spacecraft. The Company also provides space and 
satellite system simulation, satellite operations and computer system

   The Company provides integrated, computer controlled switching systems for 
the interior and exterior voice and data needs of today's Navy military 
vessels. The Company's products include Integrated Voice Communication 
Systems ("IVCS") for Aegis cruisers and destroyers and the Integrated Radio 
Room ("IRR") for Trident class submarines, the first computer controlled 
communications center in a submarine. These products integrate the intercom, 
tactical and administrative communications network into one system accessing 
various types of communication terminals throughout the ship. The Company's 
MarCom 2000 secure digital switching system is in development for the Los 
Angeles class attack submarine and provides an integrated approach to the 
specialized voice and data communications needs of a shipboard environment 
for internal and external communications, command and control and air 

                               49

   The Company has produced more than 100,000 secure telephone units ("STU 
III") which are in use today by the U.S. Armed Forces to provide secure 
telephone capabilities for classified confidential communication over public 
commercial telephone networks. The Company has begun producing the 
next-generation digital, ISDN-compatible STE. STE provides clearer voice and 
thirteen-times faster data/fax transmission capability than the STU III. STE 
also supports secure conference calls and secure video teleconferencing. STE 
uses a CryptoCard security system which consists of a small, portable, 
cryptographic module mounted on a PCMCIA card holding the algorithms, keys 
and personalized credentials to identify its user for secure communications 
access. The Company also provides LMD/KP which is the workstation component 
of the Government's Electronic Key Management System ("EKMS"), the next 
generation of information security systems. EKMS is the Government system to 
replace current "paper" secret keys used to secure government communications 
with "electronic" secret keys. LMD/KP is the component of the EKMS which 
produces and distributes the electronic keys. L-3 also develops specialized 
strategic and tactical SIGINT systems to detect, acquire, collect, and 
process information derived from electronic sources. These systems are used 
by classified customers for intelligence gathering and require high speed 
digital signal processing and high density custom hardware designs. 

o TACTICAL SECURITY SYSTEMS 

   The Company manufactures the IREMBASS, an unattended ground sensor system 
which uses sensors placed along likely avenues of enemy approach or intrusion 
in a battlefield environment. The sensors respond to seismic and acoustic 
disturbances, infrared energy and magnetic field changes and thus detect 
enemy activities. IREMBASS is currently in use by U.S. Special Operations 
Forces, the U.S. Army's Light Divisions and several foreign governments. The 
Company also provides the Intrusion Detection Early Warning System ("IDEWS"), 
a sensor system designed for platoon-level physical security applications. 
Weighing less than two pounds, this sensor system is ideal for covert 
perimeter intrusion detection, border protection and airfield or military 
installation security.

   Narda East represents approximately 65% of L-3's microwave sales volume, 
offering high performance microwave components, networks and instruments to 
the wireless, industrial and military communications markets. Narda East's 
products can be divided into three major categories: passive components, 
higher level wireless assemblies/monitoring systems and safety instruments. 

                                       50
<PAGE>
   Passive components are generally purchased in narrow frequency 
configurations by wireless OEM equipment manufacturers and service providers. 
Similar components are purchased in wide frequency configurations by first 
tier military equipment suppliers. Commercial applications for Narda 
components are primarily in cellular or PCS base stations. Narda also 
manufactures higher level assemblies for wireless base stations and the 
paging industry. These products include communication antenna test sets, 
devices that monitor reflected power to determine if a cellular base station 
antenna 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. RF safety 
products are instruments which are used to measure the level of non-ionizing 
radiation in a given area, i.e., from an antenna, test set or other emitting 
source, and determine whether human exposure limits are within federal 
standards. 

   Narda West designs and manufactures state-of-the-art space-qualified and 
wireless components. Space qualified components include channel amplifiers 
for satellite transponder control 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 constitute Narda West's main 
satellite product. These components 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 versus in-house alternatives. On a typical satellite, for which 
there are 20 to 50 channel amps, Narda West's channel amps offer cost savings 
of up to 60% (up to $1 million per satellite) and decrease launch weight by 
up to 25 kilograms. 

   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 
is of an historical nature and involves wideband filters used for electronic 
warfare applications. 

AVIONICS AND OCEAN SYSTEMS 

o  AVIATION RECORDERS 

   L-3 manufactures commercial solid-state crash-protected aviation recorders 
("black boxes") under the Fairchild brand name, and has delivered over 40,000 
flight recorders to airplane manufacturers and airlines around the world. 
Recorders are mandated and regulated by various worldwide agencies for 
commercial airlines and a large portion of business aviation aircraft. 
Management anticipates growth opportunities in Aviation Recorders as a result 
of the current high level of orders for new commercial aircraft. Expansion 
into the military market shows continued growth opportunities. L-3 Recorders 
were recently selected for installation on the fleet of the Royal Australian 
Air Force and Royal Australian Army transport aircraft and are currently 
being installed on the U.S. Navy C-9 aircraft. There are two types of 
recorders: (i) the Cockpit Voice Recorder ("CVR") which records the last 30 
to 120 minutes of crew conversation and ambient sounds from the cockpit and 
(ii) the Flight Data Recorder ("FDR") which records the last 25 hours of 
aircraft flight parameters such as speed, altitude, acceleration, thrust from 
each engine and direction of the flight in its final moments. Recorders are 
highly ruggedized instruments, designed to absorb the shock equivalent to 
that of an object traveling at 268 knots stopping in 18 inches, fire 
resistant to 1,100 degrees centigrade and pressure resistant to 20,000 feet 
undersea for 30 days. Management believes that the Company has the leading 
worldwide market position for CVR's and FDR's. 

o  ANTENNA SYSTEMS 

   Under the Randtron brand name, L-3 produces high performance antennas 
designed for surveillance, high-resolution, ultra-wide frequency bands, 
detection of low radar cross section ("LRCS") targets, LRCS 

                                       51
<PAGE>
installations, severe environmental applications and polarization diversity. 
L-3's main antenna product is a sophisticated 24-foot diameter antenna 
operational on all E-2C aircraft. This airborne antenna consists of a 24-foot 
rotating aerodynamic radome containing a UHF surveillance radar antenna, IFF 
antenna and forward and aft auxiliary antennas. Production of this antenna 
began in the early 1980s, and production is planned beyond 2000 for the E-2C, 
P-3 and C-130 AEW aircraft. The replacement for this antenna is a very 
adaptive radar currently under development for introduction early in the next 
decade. L-3 also produces broad-band antennas for a variety of tactical

TELEMETRY, INSTRUMENTATION AND SPACE 

   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 and MTSAT. 

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. 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 

                                       52
<PAGE>
from the airborne platform. Data can be encrypted and decrypted during this 
process, an additional expertise that the Company offers. The Company 
recently introduced the NeTstar satellite ground station, which collapses 
racks of satellite RF receivers, demodulators and related units into a PC. 

o  SPACE PRODUCTS 

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

target customers for its HPS include medical schools throughout the world, 
colleges with registered nursing programs, community colleges and state, 
local and volunteer emergency medical service organizations. 

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 

                                       53
<PAGE>
produce an explosive detection system ("EDS") utilizing a dual energy 
computer tomography ("CT") X-ray system. L-3's EDS system, the eXaminer 
3DX(Trademark) 6000, will analyze the contents of checked baggage at airports 
for a wide-range of explosive material as specified by the FAA. The eXaminer 
3DX(Trademark) 6000 will inspect 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. L-3 
has shipped two prototype test units and FAA certification testing commenced 
in the first quarter of 1998. 

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. In 1997, the 
Company performed under approximately 150 contracts with value exceeding $1 
million for the Government. Pro forma 1997 sales to the Government, including 
sales through prime contractors, were $651.1 million. Pro forma sales to 
Lockheed Martin were $81.6 million in 1997. The Company's largest program is 
a long-term, sole source cost plus support contract for the U-2 Program which 
contributed sales on a pro forma basis assuming the L-3 Acquisition had 
occurred on January 1, 1995, of 13%, 14%, and 14%, respectively, for 1997, 
1996 and 1995. No other program represented more than 7% of such pro forma 
sales for 1997, 1996 and 1995. 

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 December 31, 1997, the Company employed 
approximately 2,000 engineers (of whom over 20% 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 1997 were $150.2 million and $46.2 million, respectively. 

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 65% of the Company's 
1997 pro forma sales 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, AMP, Inc., Aydin 
Corporation, Cubic Corporation, GTE Corporation, Harris Corporation, Hughes, 
Motorola and Titan Corporation. A majority of the sales of the Company is 
derived from contracts with the Government and its prime contractors, and 
such contracts are awarded on the basis of negotiations or competitive bids. 
Management does not believe any one competitor or a small number of 
competitors is dominant in any of the business areas of the Company. 
Management believes the Company will continue to be able to compete 
successfully based upon the quality and cost competitiveness of its products 
and services. 

PATENTS AND LICENSES 

   Although the Company owns some patents and has filed applications for 
additional patents, it does not believe that its operations depend upon its 
patents. In addition, the Company's Government contracts 

                                       54
<PAGE>
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 December 31, 1997, the Company's pro forma funded backlog was 
approximately $638.1 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. Backlog is a more relevant predictor of future sales in the 
Secure Communication Systems business area. Current funded backlog in Secure 
Communication Systems as of December 31, 1997 was $306.0 million, of which 
approximately 93% is expected to be shipped in 1998. The Company believes 
backlog is a less relevant factor in the Specialized Communication Products 
business area given the nature of its catalog and commercial oriented 
business. Overall, approximately 85% of the Company's December 31, 1997 
funded backlog is expected to be shipped in 1998.

</TABLE>

GOVERNMENT CONTRACTS 

   Approximately 73% of the Company's 1997 pro forma sales were made to 
agencies of the Government or to prime contractors or subcontractors of the 
Government. 

   Approximately 64% of the Company's pro forma 1997 sales mix of contracts 
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 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 financial condition and 
its results of operations. 

                                       56
<PAGE>
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 believe that its environmental compliance expenditures will 
have a material adverse effect on its financial condition or results of its 
operations. 

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

   In connection with the acquisition of Ocean Systems, the Company has 
acquired the stock of ELAC. The premises currently leased by ELAC 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 current owner of the 
property, 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. 

PENSION PLANS 

   In connection with the L-3 Acquisition, Holdings and L-3 Communications 
assumed certain liabilities relating to defined benefit pension plans for 
present and former employees and retirees of certain businesses which were 
transferred from Lockheed Martin to Holdings and L-3 Communications. Prior to 
the consummation of the L-3 Acquisition, Lockheed Martin received a letter 
from the PBGC which requested information regarding the transfer of such 
pension plans and indicated that the PBGC believed certain of such pension 
plans were underfunded using the PBGC's actuarial assumptions (which 
assumptions result in a larger liability for accrued benefits than the 
assumptions used for financial reporting under FASB 87). The PBGC 
underfunding is related to the Subject Plans. As of December 31, 1997, the 
Company calculated the net funding position of the Subject Plans and believes 
them to be overfunded by approximately $5.9 million under ERISA assumptions, 
underfunded by approximately $10.2 million under FASB 87 assumptions and, on 
a termination basis, underfunded by as much as $57.5 million under PBGC 
assumptions. 

   With respect to the Subject Plans, Lockheed Martin entered into an 
agreement (the "Lockheed Martin Commitment Agreement") among Lockheed Martin, 
L-3 and the PBGC dated as of April 30, 1997. The material terms and 
conditions of the Lockheed Martin Commitment Agreement include a commitment 
by Lockheed Martin to, under certain circumstances, assume sponsorship of the 
Subject Plans or provide another form of financial support for the Subject 
Plans. The Lockheed Martin Commitment Agreement will continue with respect to 
any Subject Plan until such time as such Subject Plan is no longer 
underfunded on a PBGC basis for two consecutive years or, at any time after 
May 31, 

                                       57
<PAGE>
2002, the Company achieves investment grade credit ratings. Pursuant to the 
Lockheed Martin Commitment Agreement, the PBGC agreed that it would take no 
further action in connection with the L-3 Acquisition. 

   In return for the Lockheed Martin Commitment, the Company entered into an 
agreement with Lockheed Martin, dated as of April 30, 1997, pursuant to which 
the Company provided certain assurances to Lockheed Martin including, but not 
necessarily limited to, (i) continuing to fund the Subject Plans consistent 
with prior practices and to the extent deductible for tax purposes and, where 
appropriate, recoverable under Government contracts, (ii) agreeing to not 
increase benefits under the Subject Plans without the consent of Lockheed 
Martin, (iii) restricting the Company from a sale of any businesses employing 
individuals covered by the Subject Plans if such sale would not result in 
reduction or elimination of the Lockheed Martin Commitment with regard to the 
specific plan and (iv) if the Subject Plans were returned to Lockheed Martin, 
granting Lockheed Martin the right to seek recovery from the Company of those 
amounts actually paid, if any, by Lockheed Martin with regard to the Subject 
Plans after their return. In addition, upon the occurrence of certain events, 
Lockheed Martin, at its option, will have the right to decide whether to 
assume sponsorship of any or all of the Subject Plans, even if the PBGC has 
not sought to terminate the Subject Plans. The Company has performed its 
obligations under the letter agreement with Lockheed Martin and the Lockheed 
Martin Commitment and has not received any communications from the PBGC 
concerning actions which the PBGC contemplates taking in respect of the 
Subject Plans. 

EMPLOYEES 

   As of December 31, 1997, the Company employed approximately 6,100 
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. Three of the four collective bargaining agreements expire in 
mid-1998. While the Company has not yet initiated discussions with 
representatives of these unions, management believes it will be able to 
negotiate, without material disruption to its business, satisfactory new 
collective bargaining agreements 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 the Company's Camden operations 
will not occur. 

   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. The labor contract expires in mid-1998. While the 
Company has not yet initiated discussions with representatives of these 
unions, management believes it will be able to negotiate, without 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 material disruption to 
operations of ELAC or Ocean Systems will not occur.

<PAGE>
                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS 

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

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

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

   In the ordinary course of business L-3 sells products to Lockheed Martin 
and its affiliates. Pro forma and aggregated sales to Lockheed Martin were 
$81.6 million, $70.7 million and $25.9 million for 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 the terms relating to (i) the registration rights, (ii) 
provision of services by Lehman Brothers Inc. and (iii) the standstill 
agreement by Lockheed Martin, terminates upon the consummation of the Common 
Stock Offering. Prior to the consummation of the Common Stock Offering, the 
Lehman Partnership is entitled to designate a majority of the members of the 
Board of Directors provided that it holds at least 35% of the capital stock 
of Holdings and remains the single largest shareholder. 

   Pursuant to the Stockholders Agreement, certain of the existing 
stockholders have the right, from time to time on or after the 180-day period 
following the completion of the initial public offering and subject to 
certain conditions, to require the Company 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 

                                       59
<PAGE>
Agreement also provides certain 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 through piggyback registration rights 
granted under such agreement. 

   The Stockholders Agreement also provides that Lehman Brothers Inc. has the 
exclusive right to provide investment banking services to Holdings for the 
five-year period after the closing of the L-3 Acquisition (except that the 
exclusivity period is three years as to cash acquisitions undertaken by L-3) 
so long as the Lehman Partnership owns at least 10% of the outstanding 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%.

<PAGE>
   Upon closing of the Common Stock Offering, the Company's certificate of 
incorporation will provide 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 will select and 
engage, on behalf of the Company, the independent public accountants to audit 
the Company's annual financial statements, and will review and approve 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 of Key Employees of Holdings. 

COMPENSATION OF DIRECTORS 

   The current directors of the Company do not receive compensation for their 
services as directors. Any non-affiliated directors will receive directors' 
fees and reimbursements 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. 

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 the 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 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 descriptions 
       of the terms of these options.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION 

   The Board of Directors of Holdings established a Compensation Committee in 
June 1997. During the last 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 

                                       66
<PAGE>
Holdings or L-3 Communications. Mr. Berger resigned from Holdings' Board of 
Directors and the Compensation Committee in January 1998 and Mr. Washkowitz 
was appointed to the Compensation Committee in March 1998. Prior to the 
establishment of the Compensation Committee, all decisions relating to 
executive compensation were made by Holdings' Board of Directors. Messrs. 
Millard and Montague are affiliated with the Lehman Partnership which, 
assuming the consummation of the Common Stock Offering and full exercise of 
the over-allotment option, holds 36.6% of the Common Stock and is a party to 
the Stockholders Agreement. Pursuant to the Stockholders Agreement, the 
Lehman Partnership has the right, from time to time on or after the 180-day 
period following that completion of the initial public offering and subject 
to certain conditions, to require the Company to register under the 
Securities Act shares of Common Stock held by them. The Lehman Partnership 
has the right to request up to four demand registrations and also has 
piggyback registration rights. The Company has agreed in the Stockholders 
Agreement to pay expenses in connection with, among other things, (i) up to 
three demand registrations requested by the Lehman Partnership and (ii) any 
registration in which the existing stockholders participate through piggyback 
registration rights granted under such agreement. The Stockholders Agreement 
also provides that Lehman Brothers Inc. has the exclusive right to provide 
investment banking services to Holdings for the five-year period after the 
closing of the L-3 Acquisition (except that the exclusivity period is three 
years as to cash acquisitions undertaken by L-3) so long as the Lehman 
Partnership owns at least 10% of the outstanding Common Stock. In the event 
that Lehman Brothers Inc. agrees to provide any investment banking services 
to L-3, it will be paid fees that are mutually agreed upon based on similar 
transactions and practices in the investment banking industry. 

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

1997 STOCK OPTION PLAN 

   In April 1997, Holdings adopted the 1997 Option Plan for Key Employees of 
Holdings (the "1997 Stock Option Plan") which authorizes the Compensation 
Committee to grant options to key employees of Holdings and its subsidiaries. 
On March 10, 1998, the 1997 Stock Option Plan was amended to increase the 
shares available for option grants to 4,255,815 shares of Common Stock, of 
which 3,246,084 had been granted as of March 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, in the event of an initial 
public offering of Common Stock, 15% of the shares underlying the option 
(which would otherwise become exercisable on the second anniversary of the 
grant date) will become exercisable on the earlier to occur of (A) the 
completion of the initial public offering of the Common Stock and (B) the 
first anniversary of the grant date; (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. 


                                       67

EMPLOYMENT AGREEMENTS 

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

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

   Holdings has granted each of Messrs. Lanza and LaPenta (collectively, the 
"Equity Executives") nonqualified options to purchase, at $6.47 per share of 
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 will 
become exercisable with respect to 20% of the shares subject to the Time 
Options on March 2, 1998 and 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 will become exercisable earlier 
with respect to up to 20% of the shares subject to the Performance Options on 
March 2, 1998 and 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 (i) if 
the Equity Executive is fired for cause or resigns without good reason, the 
Options expire upon termination of employment; (ii) if the Equity Executive 
is fired without cause, resigns for good reason, dies, becomes disabled or 
retires, the Options 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.

2,944,000 shares of Class B Common Stock of Holdings will convert to Common 
Stock. Assuming such conversion, as of March 31, 1998, there were 20,457,142 
shares of Common Stock outstanding. The following table sets forth certain 
information regarding the beneficial ownership of the shares of the Common 
Stock of Holdings, as of March 31, 1998, by each person who beneficially owns 
more than five percent of the outstanding shares of Common Stock of Holdings 
and by the directors and certain executive officers of Holdings, individually

                     DESCRIPTION OF CERTAIN INDEBTEDNESS 

SENIOR CREDIT FACILITIES 

   The Senior Credit Facilities have been provided by a syndicate of banks 
and other financial institutions led by Lehman Commercial Paper Inc., as 
Arranger and Syndication Agent. The Senior Credit Facilities provide for 
$175.0 million in term loans (the "Term Loan Facilities") and for $200.0 
million in revolving credit loans (the "Revolving Credit Facility" and, 
together with the Term Loan Facilities, the "Senior Credit Facilities"). The 
Revolving Credit Facility includes borrowing capacity available for letters 
of credit and for borrowings on same-day notice (the "Swingline Loans"). The 
Term Loans, originally funded on April 30, 1997, comprised of a Tranche A 
Term Loan ($100.0 million), which had an initial maturity of six years, a 
Tranche B Term Loan ($45.0 million), which had an initial maturity of eight 
years, and a Tranche C Term Loan ($30.0 million), which had an initial 
maturity of nine years. The Revolving Loan Termination Date (as defined 
therein) is March 31, 2003. 

   All borrowings under the Senior Credit Facilities bear interest, at L-3 
Communications' option, at either: (A) a "base rate" equal to, for any day, 
the higher of: (a) 0.50% per annum above the latest Federal Funds Rate; and 
(b) the rate of interest in effect for such day as publicly announced from 
time to time by Bank of America NT&SA, as Administrative Agent, in San 
Francisco, California, as its "reference rate" plus (i) in the case of the 
Tranche A Term Loan, the Revolving Credit Facility and the Swingline Loans, a 
debt to EBITDA-dependent rate ranging from 0.50% to 1.25% per annum, (ii) in 
the case of the Tranche B Term Loan, a rate of 1.50% per annum or (iii) in 
the case of the Tranche C Term Loan, a rate of 1.75% per annum or (B) a 
"LIBOR rate" equal to, for any Interest Period (as defined in the Senior 
Credit Facilities), with respect to LIBOR Loans comprising part of the same 
borrowing, the London interbank offered rate of interest per annum for such 
Interest Period as determined by the Administrative Agent, plus (i) in the 
case of the Tranche A Term Loan and the Revolving Credit Facility, a debt to 
EBITDA-dependent rate ranging from 1.50% to 2.25% per annum, (ii) in the case 
of the Tranche B Term Loan, a rate of 2.50% per annum or (iii) in the case of 
the Tranche C Term Loan, a rate of 2.75% per annum. 

   L-3 Communications will pay a commitment fee calculated at a debt to 
EBITDA-dependent rate ranging from 0.375% to 0.50% per annum of the available 
unused commitment under the Revolving Credit Facility, in each case in effect 
on each day. Such fee will be payable quarterly in arrears and upon 
termination of the Revolving Credit Facility. 

   L-3 Communications will pay a letter of credit fee calculated at a debt to 
EBITDA-dependent rate ranging from 1.50% to 2.25% per annum of the face 
amount of each letter of credit and a fronting fee calculated at a rate equal 
to 0.125% per annum of the face amount of each letter of credit. Such fees 
will be payable quarterly in arrears and upon the termination of the 
Revolving Credit Facility. In addition, L-3 Communications will pay customary 
transaction charges in connection with any letters of credit. 

   The foregoing debt to EBITDA-dependent rates range from the low rate 
specified if the ratio of debt to EBITDA is less than 3.75 to 1.0 to the high 
rate specified if such ratio is at least equal to 4.75 to 1.0. 

   The Term Loans are subject to the following amortization schedule:

   Borrowings under the Senior Credit Facilities are subject to mandatory 
prepayment (i) with the net proceeds of any incurrence of indebtedness with 
certain exceptions to be agreed, (ii) with the proceeds of certain asset 
sales and (iii) on an annual basis with (A) 75% of the Company's excess cash 
flow (as defined in the Senior Credit Facilities) if the ratio of the 
Company's debt to EBITDA is greater than 3.5 to 1.0 or (B) 50% of such excess 
cash flow if the ratio is less than 3.5 to 1.0. 

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

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

amount of its 10 3/8% Senior Subordinated Notes due 2007 (the "1997 Notes"). 
The 1997 Notes are subject to the terms and conditions of an Indenture (the 
"1997 Indenture") dated as of April 30, 1997 between L-3 Communications and 
The Bank of New York, as trustee, a copy of which was filed as an exhibit to 
L-3 Communications' Registration Statement on Form S-4 relating to the 1997 
Notes. The 1997 Notes are subject to all of the terms and conditions of the 
1997 Indenture. The following summary of the material provisions of the 1997 
Indenture does not purport to be complete, and is subject to, and qualified 
in its entirety by reference to, all of the provisions of the 1997 Indenture 
and those terms made a part of the 1997 Indenture by the Trust Indenture Act 
of 1939, as amended. All terms defined in the 1997 Indenture and not 
otherwise defined herein are used below with the meanings set forth in the 
1997 Indenture. 

   General. The 1997 Notes will mature on May 1, 2007 and bear interest at 10 
3/8% per annum, payable semi-annually on May 1 and November 1 of each year. 
The 1997 Notes are general unsecured obligations of L-3 Communications and 
are subordinated in right of payment to all existing and future Senior Debt 
of L-3 Communications and rank pari passu with the Notes. The 1997 Notes will 
be unconditionally guaranteed, on an unsecured senior subordinated basis, 
jointly and severally, by all of L-3 Communications' future Restricted 
Subsidiaries other than Foreign Subsidiaries. 

   Optional Redemption. The 1997 Notes are subject to redemption at any time, 
at the option of L-3 Communications, in whole or in part, on or after May 1, 
2002 at redemption prices (plus accrued and unpaid interest) starting at 
105.188% of principal (plus accrued and unpaid interest) during the 12-month 
period beginning May 1, 2002 and declining annually to 100% of principal 
(plus accrued and unpaid interest) on May 1, 2005 and thereafter. 

   In addition, prior to May 1, 2000, L-3 Communications may redeem up to 35% 
of the aggregate principal amount of the 1997 Notes with the net proceeds of 
one or more Equity Offerings (as defined in the Indentures), to the extent 
such proceeds are contributed (within 120 days of any such offering) to L-3 
Communications as common equity, at a price equal to 109.375% of the 
principal (plus accrued and unpaid interest) provided that at least 65% of 
the original aggregate principal amount of the 1997 Notes remains outstanding 
thereafter. 

   Change of Control. Upon the occurrence of a Change of Control, each holder 
of the 1997 Notes may require L-3 Communications to repurchase all or a 
portion of such holder's 1997 Notes at a purchase price equal to 101% of the 
principal amount thereof (plus accrued and unpaid interest). Generally, a 
Change of Control means the occurrence of any of the following: (i) the 
disposition of all or substantially all of L-3 Communications' assets to any 
person, (ii) the adoption of a plan relating to the liquidation or 
dissolution of L-3 Communications, (iii) the consummation of any transaction 
in which a person other 

                                       71
<PAGE>
than the Principals and their Related Parties becomes the beneficial owner of 
more than 50% of the voting stock of L-3 Communications, or (iv) the first 
day on which a majority of the members of the Board of Directors of L-3 
Communications are not Continuing Directors. 

   Subordination. The 1997 Notes are general unsecured obligations of L-3 
Communications and are subordinate to all existing and future Senior Debt of 
L-3 Communications. The 1997 Notes will rank senior in right of payment to 
all subordinated Indebtedness of L-3 Communications. Any Subsidiary 
Guarantees would be general unsecured obligations of the Guarantors and are 
subordinated to the Senior Debt and to the guarantees of Senior Debt of such 
Guarantors. The Subsidiary Guarantees rank senior in right of payment to all 
subordinated Indebtedness of the Guarantors. 

   Certain Covenants. The 1997 Indenture contains a number of covenants 
restricting the operations of L-3 Communications, which, among other things, 
limit the ability of L-3 Communications to incur additional Indebtedness, pay 
dividends or make distributions, sell assets, issue subsidiary stock, 
restrict distributions from Subsidiaries, create certain liens, enter into 
certain consolidations or mergers and enter into certain transactions with 
affiliates. 

   Events of Default. Events of Default under the 1997 Indenture include the 
following: (i) a default for 30 days in the payment when due of interest on 
the 1997 Notes; (ii) default in payment when due of the principal of or 
premium, if any, on the 1997 Notes; (iii) failure by L-3 Communications to 
comply with certain provisions of the 1997 Indenture (subject, in some but 
not all cases, to notice and cure periods); (iv) default under Indebtedness 
for money borrowed by L-3 Communications or any of its Restricted 
Subsidiaries in excess of $10.0 million; (v) failure by L-3 Communications or 
any Restricted Subsidiary that would be a Significant Subsidiary to pay final 
judgments aggregating in excess of $10.0 million, which judgments are not 
paid, discharged or stayed for a period of 60 days; (vi) except as permitted 
by the Indenture, any Subsidiary Guarantee shall be held in any judicial 
proceeding to be unenforceable or invalid or shall cease for any reason to be 
in full force and effect or any Guarantor, or any Person acting on behalf of 
any Guarantor, shall deny or disaffirm its obligations under its Subsidiary 
Guarantee; or (vii) certain events of bankruptcy or insolvency with respect 
to L-3 Communications or any of its Restricted Subsidiaries. 

   Upon the occurrence of an Event of Default, with certain exceptions, the 
Trustee or the holders of at least 25% in principal amount of the then 
outstanding 1997 Notes may accelerate the maturity of all the 1997 Notes as 
provided in the 1997 Indenture.

                           DESCRIPTION OF THE NOTES 

GENERAL 

   The Notes will be issued under an indenture dated as of May 22, 1998 (the 
"Indenture") between the Company, as issuer, and The Bank of New York, as 
trustee (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 (the "Trust Indenture Act"). The Notes are 
subject to all such terms, and holders of the Notes are referred to the 
Indenture and the Trust Indenture Act for a statement thereof. The following 
summary of the material provisions of the Indenture describes the material 
terms of the Indenture but does not purport to be complete and is subject to, 
and qualified in its entirety by reference to, the provisions of the 
Indenture, including the definitions of certain terms contained therein and 
those terms made part of the Indenture by reference to the Trust Indenture 
Act. For definitions of certain capitalized terms used in the following 
summary, see "--Certain Definitions". 

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

   The Notes will be general unsecured obligations of the Company and will 
rank pari passu in right of payment with the 1997 Notes and will be 
subordinated in right of payment to all current and future Senior Debt. At 
March 31, 1998, on a pro forma basis giving effect to the 1998 Acquisitions 
and the Offerings, the Company would have had Senior Debt of approximately 
$34.9 million outstanding (excluding letters of credit). The Indenture will 
permit the incurrence of additional Senior Debt in the future. See "--Certain 
Covenants -- Incurrence of Indebtedness and Issuance of Preferred Stock". 

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

PRINCIPAL, MATURITY AND INTEREST 

   The Notes will be limited in aggregate principal amount to $250.0 million, 
of which $180.0 million will be issued in the Notes Offering. The Notes will 
mature on May 15, 2008. Interest on the Notes will accrue at the rate of 8 
1/2% per annum and will be payable semi-annually in arrears on May 15 and 
November 15, commencing on November 15, 1998, to Holders of record on the 
immediately preceding May 1 and November 1. 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 original issuance. Interest will be computed 
on the basis of a 360-day year comprised of twelve 30-day months. Principal, 
premium, if any, and interest on the Notes will be payable at the office or 
agency of the Company maintained for such purpose within the City and State 
of New York or, at the option of the Company, payment of interest may be made 
by check mailed to the Holders of the Notes at their respective addresses set 
forth in the register of Holders of Notes; provided that all payments of 
principal, premium and interest with respect to Notes the Holders of which 
have given wire transfer instructions to the Company will be required to be 
made by wire transfer of immediately available funds to the accounts 
specified by the Holders thereof if such Holders shall be registered Holders 
of at least $250,000 in principal amount of Notes. Until otherwise designated 
by the Company, the Company's office or agency in New York will be the office 
of the Trustee maintained for such purpose. The Notes will be issued in 
denominations of $1,000 and integral multiples thereof. 

OPTIONAL REDEMPTION 

   The Notes will not be redeemable at the Company's option prior to May 15, 
2003. Thereafter, the Notes will be subject to redemption at any time at the 
option of the Company, in whole or in part, upon not less than 30 nor more 
than 60 days' notice, at the redemption prices (expressed as percentages 


                                       73
<PAGE>
of principal amount) set forth below plus accrued and unpaid interest to the 
applicable redemption date, if redeemed during the twelve-month period 
beginning on May 15 of the years indicated below: 

<TABLE>
<CAPTION>
 YEAR                  PERCENTAGE 
- --------------------  ------------ 
<S>                   <C>
2003 ................    104.250% 
2004 ................    102.833% 
2005 ................    101.417% 
2006 and thereafter      100.000% 
</TABLE>

   Notwithstanding the foregoing, during the first 36 months after the Issue 
Date, the Company may on any one or more occasions redeem up to an aggregate 
of 35% of the Notes originally issued at a redemption price of 108.500% of 
the principal amount thereof, plus accrued and unpaid interest to the 
redemption date, with the net cash proceeds of one or more Equity Offerings 
by the Company or the net cash proceeds of one or more Equity Offerings by 
Holdings that are contributed to the Company as common equity capital; 
provided that at least 65% of the Notes originally issued remain outstanding 
immediately after the occurrence of each such redemption; and provided, 
further, that any such redemption must occur within 120 days of the date of 
the closing of such Equity Offering. 

SUBORDINATION 

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

   Upon any distribution to creditors of the Company in a liquidation or 
dissolution of the Company or in a bankruptcy, reorganization, insolvency, 
receivership or similar proceeding relating to the Company or its property, 
an assignment for the benefit of creditors or any marshalling of the 
Company's assets and liabilities, the holders of Senior Debt will be entitled 
to receive payment in full in cash of all Obligations due in respect of such 
Senior Debt (including interest after the commencement of any such proceeding 
at the rate specified in the applicable Senior Debt, whether or not an 
allowable claim in any such proceeding) before the Holders of 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, 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 
"--Legal Defeasance and Covenant Defeasance"). 

   The Company also may not make any payment upon or in respect of the Notes 
(except from the trust described under "--Legal Defeasance and Covenant 
Defeasance") if (i) a default in the payment of the principal of, premium, if 
any, or interest on Designated Senior Debt occurs and is continuing or (ii) 
any other default occurs and is continuing with respect to Designated Senior 
Debt that permits holders of the Designated Senior Debt as to which such 
default relates to accelerate its maturity (or that would permit such holders 
to accelerate with the giving of notice or the passage of time or both) and 
the Trustee receives a notice of such default (a "Payment Blockage Notice") 
from the Company or the holders of any Designated Senior Debt. Payments on 
the Notes may and shall be resumed (A) in the case of a payment default, upon 
the date on which such default is cured or waived and (B) in case of a 
nonpayment default, the earlier of the date on which such nonpayment default 
is cured or waived or 179 days after the date on which the applicable Payment 
Blockage Notice is received, unless the maturity of any Designated Senior 
Debt has been accelerated. No new period of payment blockage may be commenced 
unless and until (i) 360 days have elapsed since the effectiveness of the 
immediately prior Payment Blockage Notice and (ii) all scheduled payments of 
principal, premium, 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 for a period of not less 
than 90 days. 

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

                                       74
<PAGE>
   As a result of the subordination provisions described above, in the event 
of a liquidation or insolvency, Holders of Notes may recover less ratably 
than creditors of the Company who are holders of Senior Debt. On a pro forma 
basis, after giving effect to the Offerings and the 1998 Acquisitions, the 
principal amount of Senior Debt outstanding (excluding letters of credit) at 
March 31, 1998 would have been approximately $34.9 million. 

SELECTION AND NOTICE 

   If less than all of the Notes are to be redeemed at any time, selection of 
Notes for redemption will be made by the Trustee in compliance with the 
requirements of the principal national securities exchange, if any, on which 
the 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 will 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. 

MANDATORY REDEMPTION 

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

REPURCHASE AT THE OPTION OF HOLDERS 

 CHANGE OF CONTROL 

   Upon the occurrence of a Change of Control, each Holder of Notes will have 
the right to require the Company to repurchase all or any part (equal to 
$1,000 or an integral multiple thereof) of such Holder's Notes pursuant to 
the offer described below (the "Change of Control Offer") at an offer price 
in cash equal to 101% of the aggregate principal amount thereof plus accrued 
and unpaid interest to the date of purchase (the "Change of Control 
Payment"). Within ten days following any Change of Control, the Company will 
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"), pursuant to the procedures required by the Indenture 
and described in such notice. The Company will comply with the requirements 
of Rule 14e-1 under the Exchange Act and any other securities laws and 
regulations thereunder to the extent such laws and regulations are applicable 
in connection with the repurchase of the Notes as a result of a Change of 
Control. 

   On the Change of Control Payment Date, the Company will, to the extent 
lawful, (i) accept for payment all 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 will promptly mail 
to each Holder of Notes so tendered the Change of Control Payment for such 
Notes, and the Trustee will 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 will be in a principal amount of $1,000 or an 
integral multiple thereof. 

   The Indenture will provide that, prior to mailing a Change of Control 
Offer, but in any event within 90 days following a Change of Control, the 
Company will either repay all outstanding Senior Debt or offer to repay all 
Senior Debt and terminate all commitments thereunder of each lender who has 
accepted such 

                                       75
<PAGE>
offer or obtain the requisite consents, if any, under all agreements 
governing outstanding Senior Debt to permit the repurchase of Notes required 
by this covenant. The Company will publicly announce the results of the 
Change of Control Offer on or as soon as practicable after the Change of 
Control Payment Date. 

   The Change of Control provisions described above will be applicable 
whether or not any other provisions of the Indenture are applicable. Except 
as described above with respect to a Change of Control, the Indenture does 
not contain provisions that permit the Holders of the Notes to require that 
the Company repurchase or redeem the Notes in the event of a takeover, 
recapitalization or similar transaction. 

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

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

   "Change of Control" means the occurrence of any of the following: (i) the 
sale, lease, transfer, conveyance or other disposition (other than by way of 
merger or consolidation), in one or a series of related transactions, of all 
or substantially all of the assets of the Company and its Restricted 
Subsidiaries taken as a whole to any "person" (as such term is used in 
Section 13(d)(3) of the Exchange Act) other than the Principals or their 
Related Parties (as defined below), (ii) the adoption of a plan relating to 
the liquidation or dissolution of the Company, (iii) the consummation of any 
transaction (including, without limitation, any merger or consolidation) the 
result of which is that any "person" (as defined above), other than the 
Principals and their Related Parties, becomes the "beneficial owner" (as such 
term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), 
directly or indirectly, of more than 50% of the Voting Stock of the Company 
(measured by voting power rather than number of shares) or (iv) the first day 
on which a majority of the members of the Board of Directors of the Company 
are not Continuing Directors. 

   "Continuing Directors" means, as of any date of determination, any member 
of the Board of Directors of the Company who (i) was a member of such Board 
of Directors on the Issue Date or (ii) was nominated for election or elected 
to such Board of Directors with the approval of a majority of the Continuing 
Directors who were members of such Board at the time of such nomination or 
election. 

                                       76
<PAGE>
   "Principals" means any Lehman Investor, Lockheed Martin Corporation, Frank 
C. Lanza and Robert V. LaPenta. 

   "Related Party" with respect to any Principal means (i) any controlling 
stockholder, 50% (or more) owned Subsidiary, or spouse or immediate family 
member (in the case of an individual) of such Principal or (ii) any trust, 
corporation, partnership or other entity, the beneficiaries, stockholders, 
partners, owners or Persons beneficially holding a more than 50% controlling 
interest of which consist of such Principal and/or such other Persons 
referred to in the immediately preceding clause (i). 

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

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

 ASSET SALES 

   The Indenture will provide that the Company will not, and will not permit 
any of its Restricted Subsidiaries to, consummate an Asset Sale unless (i) 
the Company (or the Restricted Subsidiary, as the case may be) receives 
consideration at the time of such Asset Sale at least equal to the fair 
market value (evidenced by an Officers' Certificate delivered to the Trustee 
which will include a resolution of the Board of Directors with respect to 
such fair market value in the event such Asset Sale involves aggregate 
consideration in excess of $5.0 million) of the assets or Equity Interests 
issued or sold or otherwise disposed of and (ii) at least 80% of the 
consideration therefor received by the Company or such Restricted Subsidiary, 
as the case may be, consists of cash, Cash Equivalents and/or Marketable 
Securities; provided, however, that (A) the amount of any Senior Debt of the 
Company or such Restricted Subsidiary that is assumed by the transferee in 
any such transaction and (B) any consideration received by the Company or 
such Restricted Subsidiary, as the case may be, that consists of (1) all or 
substantially all of the assets of one or more Similar Businesses, (2) other 
long-term assets that are used or useful in one or more Similar Businesses 
and (3) Permitted Securities shall be deemed to be cash for purposes of this 
provision. 

   Within 365 days after the receipt of any Net Proceeds from an Asset Sale, 
the Company may apply such Net Proceeds, at its option, (i) to repay 
Indebtedness under a Credit Facility, or (ii) to the acquisition of Permitted 
Securities, all or substantially all of the assets of one or more Similar 
Businesses, or the making of a capital expenditure or the acquisition of 
other long-term assets in a Similar Business. Pending the final application 
of any such Net Proceeds, the Company may temporarily reduce Indebtedness 
under a Credit Facility or otherwise invest such Net Proceeds in any manner 
that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales 
that are not applied or invested as provided in the first sentence of this 
paragraph will be deemed to constitute "Excess Proceeds". When the aggregate 
amount of Excess Proceeds exceeds $10.0 million, the 1997 Indenture provides 
that the Company will be required to make an offer to all holders of 1997 
Notes (an "Asset Sale Offer") to purchase the maximum principal amount of 
1997 Notes that may be purchased out of the Excess Proceeds, at an offer 
price in cash in an amount equal to 100% of the principal amount thereof plus 
accrued and unpaid interest to the date of purchase, in accordance with the 
procedures set forth in the 1997 Indenture. To the extent that the aggregate 
amount of 1997 Notes tendered pursuant to an Asset Sale Offer is less than 
the remaining Excess Proceeds ("Remaining Excess Proceeds") and the sum of 
(A) such amount of Remaining Excess Proceeds and (B) the Remaining Excess 
Proceeds from any subsequent Asset Sale Offers exceeds $3.0 million, the 
Company will be required to make an offer to all Holders of Notes and any 
other Indebtedness that ranks pari passu with the Notes that, by its terms, 
requires the Company to offer to 

                                       77
<PAGE>
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. Upon 
completion of such offer to purchase, the amount of Excess Proceeds shall be 
reset at zero. 

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

CERTAIN COVENANTS 

 RESTRICTED PAYMENTS 

   The Indenture will provide that the Company will not, and will not permit 
any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or 
pay any dividend or make any other payment or distribution on account of the 
Company's or any of its Restricted Subsidiaries' Equity Interests (including, 
without limitation, any payment in connection with any merger or 
consolidation involving the Company) or to the direct or indirect holders of 
the Company's or any of its Restricted Subsidiaries' Equity Interests in 
their capacity as such (other than (A) dividends or distributions payable in 
Equity Interests (other than Disqualified Stock) of the Company or (B) 
dividends or distributions by a Restricted 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 
    the covenant described below under caption "Incurrence of Indebtedness and 
    Issuance of Preferred Stock"; and 

     (c) such Restricted Payment, together with the aggregate amount of all 
    other Restricted Payments made by the Company and its Restricted 
    Subsidiaries since April 30, 1997 (excluding Restricted Payments permitted 
    by clauses (ii) through (vii) of the next succeeding paragraph or of the 
    kind contemplated by such clauses that were made prior to the date of the 
    Indenture), is less than the sum of (i) 50% of the Consolidated Net Income 
    of the Company for the period (taken as one accounting period) from July 
    1, 1997 to the end of the Company's most recently ended fiscal quarter for 
    which internal financial statements are available at the time of such 
    Restricted Payment (or, if such Consolidated Net Income for such period is 
    a deficit, less 100% of such deficit), plus (ii) 100% 


                                       78
<PAGE>
    of the aggregate net cash proceeds received by the Company since April 30, 
    1997 from a contribution to its common equity capital or the issue or sale 
    of Equity Interests of the Company (other than Disqualified Stock) or of 
    Disqualified Stock or debt securities of the Company that have been 
    converted into such Equity Interests (other than Equity Interests (or 
    Disqualified Stock or convertible debt securities) sold to a Subsidiary of 
    the Company and other than Disqualified Stock or convertible debt 
    securities that have been converted into Disqualified Stock), plus (iii) 
    to the extent that any Restricted Investment that was made after April 30, 
    1997 is sold for cash or otherwise liquidated or repaid for cash, the 
    amount of cash received in connection therewith (or from the sale of 
    Marketable Securities received in connection therewith), plus (iv) to the 
    extent not already included in such Consolidated Net Income of the Company 
    for such period and without duplication, (A) 100% of the aggregate amount 
    of cash received as a dividend from an Unrestricted Subsidiary, (B) 100% 
    of the cash received upon the sale of Marketable Securities received as a 
    dividend from an Unrestricted Subsidiary, and (C) 100% of the net assets 
    of any Unrestricted Subsidiary on the date that it becomes a Restricted 
    Subsidiary. As of December 31, 1997 (without giving effect to the Common 
    Stock Offering), the amount that would have been available to the Company 
    for Restricted Payments pursuant to this paragraph (c) would have been 
    $6.8 million. 

   The foregoing provisions will not prohibit: 

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

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

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

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

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

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

     (vii) other Restricted Payments in an aggregate amount since the Issue 
    Date not to exceed $20.0 million. 

   The Board of Directors of the Company may designate any Restricted 
Subsidiary to be an Unrestricted Subsidiary if such designation would not 
cause a Default. For purposes of making such 


                                       79
<PAGE>
determination, all outstanding Investments by the Company and its Restricted 
Subsidiaries (except to the extent repaid in cash) in the Subsidiary so 
designated will be deemed to be Restricted Payments at the time of such 
designation and will reduce the amount available for Restricted Payments 
under the first paragraph of this covenant. All such outstanding Investments 
will be deemed to constitute Investments in an amount equal to the fair 
market value of such Investments at the time of such designation. Such 
designation will only be permitted if such Restricted Payment would be 
permitted at such time and if such Restricted Subsidiary otherwise meets the 
definition of an Unrestricted Subsidiary. 

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

 INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK 

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

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

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

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

     (iii) the incurrence by the Company and the Guarantors of $180.0 million 
    in aggregate principal amount of the Notes and the Subsidiary Guarantees 
    thereof; 

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


                                       80
<PAGE>
     (v) the incurrence by the Company or any of its Restricted Subsidiaries 
    of Indebtedness in connection with the acquisition of assets or a new 
    Restricted Subsidiary; provided that such Indebtedness was incurred by the 
    prior owner of such assets or such Restricted Subsidiary prior to such 
    acquisition by the Company or one of its Restricted Subsidiaries and was 
    not incurred in connection with, or in contemplation of, such acquisition 
    by the Company or one of its Restricted Subsidiaries; and provided further 
    that the principal amount (or accreted value, as applicable) of such 
    Indebtedness, together with any other outstanding Indebtedness incurred 
    pursuant to this clause (v), does not exceed $10.0 million; 

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

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

     (viii) Indebtedness arising from agreements of the Company or a 
    Restricted Subsidiary providing for indemnification, adjustment of 
    purchase price or similar obligations, in each case, incurred or assumed 
    in connection with the disposition of any business, assets or a 
    Subsidiary, other than guarantees of Indebtedness incurred by any Person 
    acquiring all or any portion of such business, assets or a Subsidiary for 
    the purpose of financing such acquisition; provided, however, that (A) 
    such Indebtedness is not reflected on the balance sheet of the Company or 
    any Restricted Subsidiary (contingent obligations referred to in a 
    footnote to financial statements and not otherwise reflected on the 
    balance sheet will not be deemed to be reflected on such balance sheet for 
    purposes of this clause (A)) and (B) the maximum assumable liability in 
    respect of all such Indebtedness shall at no time exceed the gross 
    proceeds including noncash proceeds (the fair market value of such noncash 
    proceeds being measured at the time received and without giving effect to 
    any subsequent changes in value) actually received by the Company and its 
    Restricted Subsidiaries in connection with such disposition; 

     (ix) the incurrence by the Company or any of its Restricted Subsidiaries 
    of intercompany Indebtedness between or among the Company and any of its 
    Restricted Subsidiaries; provided, however, that (A) if the Company is the 
    obligor on such Indebtedness, such Indebtedness is expressly subordinated 
    to the prior payment in full in cash of all Obligations with respect to 
    the Notes and (B)(1) any subsequent issuance or transfer of Equity 
    Interests that results in any such Indebtedness being held by a Person 
    other than the Company or one of its Restricted Subsidiaries and (2) any 
    sale or other transfer of any such Indebtedness to a Person that is not 
    either the Company or one of its Restricted Subsidiaries shall be deemed, 
    in each case, to constitute an incurrence of such Indebtedness by the 
    Company or such Restricted Subsidiary, as the case may be; 

     (x) the incurrence by the Company or any of the Guarantors of Hedging 
    Obligations that are incurred for the purpose of (A) fixing, hedging or 
    capping interest rate risk with respect to any floating rate Indebtedness 
    that is permitted by the terms of the Indenture to be outstanding or (B) 
    protecting the Company and its Restricted Subsidiaries against changes in 
    currency exchange rates; 

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

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


                                       81
<PAGE>
     (xiii) obligations in respect of performance and surety bonds and 
    completion guarantees provided by the Company or any Restricted 
    Subsidiaries in the ordinary course of business; and 

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

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

 LIENS 

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

 ANTILAYERING PROVISION 

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

 DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES 

   The Indenture will provide that the Company will not, and will not permit 
any of its Restricted Subsidiaries to, directly or indirectly, create or 
otherwise cause or suffer to exist or become effective any encumbrance or 
restriction on the ability of any Restricted Subsidiary to (i)(A) pay 
dividends or make any other distributions to the Company or any of its 
Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any 
other interest or participation in, or measured by, its profits, or (B) pay 
any indebtedness owed to the Company or any of its Restricted Subsidiaries, 
(ii) make loans or advances to the Company or any of its Restricted 
Subsidiaries or (iii) transfer any of its properties or assets to the Company 
or any of its Restricted Subsidiaries, except for such encumbrances or 
restrictions existing under or by reason of (A) the provisions of security 
agreements that restrict the transfer of assets that are subject to a Lien 
created by such security agreements, (B) the provisions of agreements 
governing Indebtedness incurred pursuant to clause (v) of the second 
paragraph of the covenant described above under the caption "--Incurrence of 
Indebtedness and Issuance of Preferred Stock", (C) the Indenture, the Notes, 
and the 1997 Indenture and the 1997 Notes, (D) applicable law, (E) any 
instrument governing Indebtedness or Capital Stock of a Person acquired by 
the Company or any of its Restricted Subsidiaries as in effect at the time of 
such acquisition (except to the extent such Indebtedness was incurred in 
connection with or in contemplation of such acquisition), which encumbrance 
or restriction is not applicable to any Person, or the properties or assets 
of any Person, other than the Person, or the property or assets of the 
Person, so acquired, provided that, in the case of Indebtedness, such 
Indebtedness was permitted by the terms of the Indenture to be incurred, (F) 
by reason of customary non-assignment provisions in leases entered into in 
the ordinary course of business and consistent with past practices, (G) 
purchase money obligations for property acquired in the ordinary course of 
business that impose 

                                       82
<PAGE>
restrictions of the nature described in clause (iii) above on the property so 
acquired, (H) Permitted Refinancing Indebtedness, provided that the 
restrictions contained in the agreements governing such Permitted Refinancing 
Indebtedness are no more restrictive than those contained in the agreements 
governing the Indebtedness being refinanced, (I) contracts for the sale of 
assets, including, without limitation, customary restrictions with respect to 
a Subsidiary pursuant to an agreement that has been entered into for the sale 
or disposition of all or substantially all of the Capital Stock or assets of 
such Subsidiary, (J) agreements relating to secured Indebtedness otherwise 
permitted to be incurred pursuant to the covenants described under 
"Limitations on Incurrence of Indebtedness and Issuance of Preferred Stock" 
and "Liens" that limit the right of the debtor to dispose of the assets 
securing such Indebtedness, (K) restrictions on cash or other deposits or net 
worth imposed by customers under contracts entered into in the ordinary 
course of business, or (L) customary provisions in joint venture agreements 
and other similar agreements entered into in the ordinary course of business. 

 MERGER, CONSOLIDATION OR SALE OF ASSETS 

   The Indenture will provide that the Company may not consolidate or merge 
with or into (whether or not the Company is the surviving corporation), or 
sell, assign, transfer, lease, convey or otherwise dispose of all or 
substantially all of its properties or assets in one or more related 
transactions, to another corporation, Person or entity unless (i) the Company 
is the surviving corporation or the entity or the Person formed by or 
surviving any such consolidation or merger (if other than the Company) or to 
which such sale, assignment, transfer, lease, conveyance or other disposition 
shall have been made is a corporation organized or existing under the laws of 
the United States, any state thereof or the District of Columbia; (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 the 
Indenture pursuant to a supplemental indenture in a form reasonably 
satisfactory to the Trustee; (iii) immediately after such transaction no 
Default or Event of Default exists; and (iv) except in the case of a merger 
of the Company with or into a Wholly Owned Restricted Subsidiary of the 
Company, the Company or the entity or Person formed by or surviving any such 
consolidation or merger (if other than the Company), or to which such sale, 
assignment, transfer, lease, conveyance or other disposition shall have been 
made, after giving pro forma effect to such transaction as if such 
transaction had occurred at the beginning of the most recently ended four 
full fiscal quarters for which internal financial statements are available 
immediately preceding such transaction either (A) would be permitted to incur 
at least $1.00 of additional Indebtedness pursuant to the Fixed Charge 
Coverage Ratio test set forth in the first paragraph of the covenant 
described above under the caption "--Incurrence of Indebtedness and Issuance 
of Preferred Stock" or (B) would have a pro forma Fixed Charge Coverage Ratio 
that is greater than the actual Fixed Charge Coverage Ratio for the same 
four-quarter period without giving pro forma effect to such transaction. 

   Notwithstanding the foregoing clause (iv), (i) any Restricted Subsidiary 
may consolidate with, merge into or transfer all or part of its properties 
and assets to the Company and (ii) the Company may merge with an Affiliate 
that has no significant assets or liabilities and was incorporated solely for 
the purpose of reincorporating the Company in another State of the United 
States so long as the amount of Indebtedness of the Company and its 
Restricted Subsidiaries is not increased thereby. 

 TRANSACTIONS WITH AFFILIATES 

   The Indenture will provide that the Company will not, and will not permit 
any of its Restricted Subsidiaries to, make any payment to, or sell, lease, 
transfer or otherwise dispose of any of its properties or assets to, or 
purchase any property or assets from, or enter into or make or amend any 
transaction, contract, agreement, understanding, loan, advance or guarantee 
with, or for the benefit of, any Affiliate (each of the foregoing, an 
"Affiliate Transaction"), unless (i) such Affiliate Transaction is on terms 
that are no less favorable to the Company or the relevant Restricted 
Subsidiary than those that would have been obtained in a comparable 
transaction by the Company or such Restricted Subsidiary with an unrelated 
Person and (ii) the Company delivers to the Trustee (A) with respect to any 
Affiliate 

                                       83
<PAGE>
Transaction or series of related Affiliate Transactions involving aggregate 
consideration in excess of $5.0 million, a resolution of the Board of 
Directors set forth in an Officers' Certificate certifying that such 
Affiliate Transaction complies with clause (i) above and that such Affiliate 
Transaction has been approved by a majority of the disinterested members of 
the Board of Directors and (B) with respect to any Affiliate Transaction or 
series of related Affiliate Transactions involving aggregate consideration in 
excess of $15.0 million, an opinion as to the fairness to the Holders of such 
Affiliate Transaction from a financial point of view issued by an accounting, 
appraisal or investment banking firm of national standing. 

   The foregoing provisions will not prohibit: (i) any employment agreement 
entered into by the Company or any of its Restricted Subsidiaries in the 
ordinary course of business; (ii) any transaction with a Lehman Investor; 
(iii) any transaction between or among the Company and/or its Restricted 
Subsidiaries; (iv) transactions between the Company or any of its Restricted 
Subsidiaries, on the one hand, and Lockheed Martin or any of its Subsidiaries 
or a Permitted Joint Venture, on the other hand, on terms that are not 
materially less favorable to the Company or the applicable Restricted 
Subsidiary of the Company than those that could have been obtained from an 
unaffiliated third party; provided that (A) in the case of any such 
transaction or series of related transactions pursuant to this clause (iv) 
involving aggregate consideration in excess of $5.0 million but less than 
$25.0 million, such transaction or series of transactions (or the agreement 
pursuant to which the transactions were executed) was approved by the 
Company's Chief Executive Officer or Chief Financial Officer and (B) in the 
case of any such transaction or series of related transactions pursuant to 
this clause (iv) involving aggregate consideration equal to or in excess of 
$25.0 million, such transaction or series of related transactions (or the 
agreement pursuant to which the transactions were executed) was approved by a 
majority of the disinterested members of the Board of Directors; (v) any 
transaction pursuant to and in accordance with the provisions of the 
Transaction Documents as the same are in effect on the Issue Date; and (vi) 
any Restricted Payment that is permitted by the provisions of the Indenture 
described above under the caption "--Restricted Payments".

   The Indenture will provide that neither the Company nor any of its 
Subsidiaries will, directly or indirectly, pay or cause to be paid any 
consideration, whether by way of interest, fee or otherwise, to any Holder of 
any Notes for or as an inducement to any consent, waiver or amendment of any 
of the terms or provisions of the 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. 

 REPORTS 

   Notwithstanding that the Company may not be subject to the reporting 
requirements of Section 13 or 15(d) of the Exchange Act or otherwise report 
on an annual and quarterly basis on forms provided for such annual and 
quarterly reporting pursuant to rules and regulations promulgated by the 
Commission, the Indenture will require the Company to file with the 
Commission (and provide the Trustee and Holders with copies thereof, without 
cost to each Holder, within 15 days after it files them with the Commission), 
(a) within 90 days after the end of each fiscal year, annual reports on Form 
10-K (or any successor or comparable form) containing the information 
required to be contained therein (or required in such successor or comparable 
form); (b) within 45 days after the end of each of the first three fiscal 
quarters of each fiscal year, reports on Form 10-Q (or any successor or 
comparable form); (c) promptly from time to time after the occurrence of an 
event required to be therein reported, such other reports on Form 8-K (or any 
successor or comparable form); and (d) any other information, documents and 
other reports which the Company would be required to file with the Commission 
if it were subject to Section 13 or 15(d) of the Exchange Act; provided, 
however, the Company shall not be so obligated to file such reports with the 
Commission if the Commission does not permit such filing, in which event the 
Company will make available such information to prospective purchasers of 
Notes, in addition to providing such information to the Trustee and the 
Holders, in each case within 15 days after the time the Company would be 
required to file such information with the Commission, if it were subject to 
Sections 13 or 15(d) of the Exchange Act.

 FUTURE SUBSIDIARY GUARANTEES 

   The Company's payment obligations under the Notes will be jointly and 
severally guaranteed by all of the Company's existing and future Restricted 
Subsidiaries, other than Foreign Subsidiaries. The Indenture will provide 
that if the Company or any of its Subsidiaries shall acquire or create a 
Subsidiary (other than a Foreign Subsidiary or an Unrestricted Subsidiary) 
after the Issue Date, then such Subsidiary shall execute a Subsidiary 
Guarantee and deliver an opinion of counsel, in accordance with the terms of 
the Indenture. The Subsidiary Guarantee of each Guarantor will rank pari 
passu with the guarantees of the Original Notes 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. 

   The Indenture will provide that no Guarantor may consolidate with or merge 
with or into (whether or not such Guarantor is the surviving Person) another 
Person (except the Company or another Guarantor) unless (i) subject to the 
provisions of the following paragraph, the Person formed by or surviving any 
such consolidation or merger (if other than such Guarantor) or to which such 
sale, assignment, transfer, lease, conveyance or other disposition shall have 
been made assumes all the obligations of such Guarantor pursuant to a 
supplemental indenture in form and substance reasonably satisfactory to the 
Trustee, under the Notes and the Indenture; (ii) immediately after giving 
effect to such transaction, no Default or Event of Default exists; and (iii) 
the Company (A) would be permitted by virtue of the Company's pro forma Fixed 
Charge Coverage Ratio, immediately after giving effect to such transaction, 
to incur at least $1.00 of additional Indebtedness pursuant to the Fixed 
Charge Coverage Ratio test set forth in the covenant described above under 
the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock" or 
(B) would have a pro forma Fixed Charge Coverage Ratio that is greater than 
the actual Fixed Charge Coverage Ratio for the same four-quarter period 
without giving pro forma effect to such transaction. 

   Notwithstanding the foregoing paragraph, (i) any Guarantor may consolidate 
with, merge into or transfer all or part of its properties and assets to the 
Company and (ii) any Guarantor may merge with an Affiliate that has no 
significant assets or liabilities and was incorporated solely for the purpose 
of reincorporating such Guarantor in another State of the United States so 
long as the amount of Indebtedness of the Company and its Restricted 
Subsidiaries is not increased thereby. 

   The Indenture will provide that in the event of a sale or other 
disposition of all of the assets of any Guarantor, by way of merger, 
consolidation or otherwise, or a sale or other disposition of all of the 
capital stock of any Guarantor, then such Guarantor (in the event of a sale 
or other disposition, by way of such a merger, consolidation or otherwise, of 
all of the capital stock of such Guarantor) or the corporation acquiring the 
property (in the event of a sale or other disposition of all of the assets of 
such Guarantor) will be released and relieved of any obligations under its 
Subsidiary Guarantee; provided that the Net Proceeds of such sale or other 
disposition are applied in accordance with the applicable provisions of the 
Indenture. See "--Repurchase at Option of Holders -- Asset Sales". 

EVENTS OF DEFAULT AND REMEDIES 

   The Indenture will provide that each of the following constitutes an Event 
of Default: (i) default for 30 days in the payment when due of interest on 
the Notes (whether or not prohibited by the subordination provisions of the 
Indenture); (ii) default in payment when due of the principal of or premium, 
if any, on the Notes (whether or not prohibited by the subordination 
provisions of the Indenture); (iii) failure by the Company to comply with the 
provisions described under the captions "--Change of Control", "--Asset 
Sales" or "--Merger, Consolidation or Sale of Assets"; (iv) failure by the 
Company for 60 days after notice to comply with any of its other agreements 
in the Indenture or the 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 

                                       85
<PAGE>
any such Indebtedness, together with the principal amount of any other such 
Indebtedness the maturity of which has been so accelerated, aggregates $10.0 
million or more; (vi) failure by the Company or any of its Restricted 
Subsidiaries to pay final judgments aggregating in excess of $10.0 million, 
which judgments are not paid, discharged or stayed for a period of 60 days; 
(vii) certain events of bankruptcy or insolvency with respect to the Company 
or any of its Restricted Subsidiaries; and (viii) except as permitted by the 
Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding 
to be unenforceable or invalid. 

   If any Event of Default occurs and is continuing, the Trustee or the 
Holders of at least 25% in principal amount of the then outstanding Notes may 
declare all the Notes to be due and payable immediately; provided, however, 
that so long as any Designated Senior Debt is outstanding, such declaration 
shall not become effective until the earlier of (i) the day which is five 
Business Days after receipt by the Representatives of Designated Senior Debt 
of such notice of acceleration or (ii) the date of acceleration of any 
Designated Senior Debt. Notwithstanding the foregoing, in the case of an 
Event of Default arising from certain events of bankruptcy or insolvency, 
with respect to the Company or any Restricted Subsidiary, all outstanding 
Notes will become due and payable without further action or notice. Holders 
of the Notes may not enforce the Indenture or the Notes except as provided in 
the Indenture. Subject to certain limitations, Holders of a majority in 
principal amount of the then outstanding Notes may direct the Trustee in its 
exercise of any trust or power. The Trustee may withhold from Holders of the 
Notes notice of any continuing Default or Event of Default (except a Default 
or Event of Default relating to the payment of principal or interest) if it 
determines that withholding notice is in their interest. 

   In the case of any Event of Default occurring by reason of any willful 
action (or inaction) taken (or not taken) by or on behalf of the Company with 
the intention of avoiding payment of the premium that the Company would have 
had to pay if the Company then had elected to redeem the Notes pursuant to 
the optional redemption provisions of the Indenture, an equivalent premium 
shall also become and be immediately due and payable to the extent permitted 
by law upon the acceleration of the Notes. If an Event of Default occurs 
prior to May 15, 2003 by reason of any willful action (or inaction) taken (or 
not taken) by or on behalf of the Company with the intention of avoiding the 
prohibition on redemption of the Notes prior to May 15, 2003, then the 
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. 

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

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS 

   No director, officer, employee, incorporator or stockholder of the 
Company, as such, shall have any liability for any obligations of the Company 
under the Notes and the Indenture or for any claim based on, in respect of, 
or by reason of, such obligations or their creation. Each Holder of 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. 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

   The Company may, at its option and at any time, elect to have all of its 
obligations discharged with respect to the outstanding Notes ("Legal 
Defeasance") except for (i) the rights of Holders of outstanding Notes to 
receive payments in respect of the principal of, premium, if any, and 
interest on such Notes when such payments are due from the trust referred to 
below, (ii) the Company's obligations with respect to the Notes concerning 
issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or 
stolen 

                                       86
<PAGE>
Notes and the maintenance of an office or agency for payment and money for 
security payments held in trust, (iii) the rights, powers, trusts, duties and 
immunities of the Trustee, and the Company's obligations in connection 
therewith and (iv) the Legal Defeasance provisions of the Indenture. In 
addition, the Company may, at its option and at any time, elect to have the 
obligations of the Company released with respect to certain covenants that 
are described in the Indenture ("Covenant Defeasance") and thereafter any 
omission to comply with such obligations shall not constitute a Default or 
Event of Default with respect to the Notes. In the event Covenant Defeasance 
occurs, certain events (not including non-payment, bankruptcy, receivership, 
rehabilitation and insolvency events) described under "Events of Default" 
will no longer constitute an Event of Default with respect to the Notes. 

   In order to exercise either Legal Defeasance or Covenant Defeasance, (i) 
the Company must irrevocably deposit with the Trustee, in trust, for the 
benefit of the Holders of the Notes, cash in U.S. dollars, non-callable 
Government Securities, or a combination thereof, in such amounts as will be 
sufficient, in the opinion of a nationally recognized firm of independent 
public accountants, to pay the principal of, premium, if any, and interest on 
the outstanding Notes on the stated maturity or on the applicable redemption 
date, as the case may be, and the Company must specify whether the Notes are 
being defeased to maturity or to a particular redemption date; (ii) in the 
case of Legal Defeasance, the Company shall have delivered to the Trustee an 
opinion of counsel in the United States reasonably acceptable to the Trustee 
confirming that (A) the Company has received from, or there has been 
published by, the Internal Revenue Service a ruling or (B) since the Issue 
Date, there has been a change in the applicable federal income tax law, in 
either case to the effect that, and based thereon such opinion of counsel 
shall confirm that, the Holders of the outstanding Notes will not recognize 
income, gain or loss for federal income tax purposes as a result of such 
Legal Defeasance and will be subject to federal income tax on the same 
amounts, in the same manner and at the same times as would have been the case 
if such Legal Defeasance had not occurred; (iii) in the case of Covenant 
Defeasance, the Company shall have delivered to the Trustee an opinion of 
counsel in the United States reasonably acceptable to the Trustee confirming 
that the Holders of the outstanding Notes will not recognize income, gain or 
loss for federal income tax purposes as a result of such Covenant Defeasance 
and will be subject to federal income tax on the same amounts, in the same 
manner and at the same times as would have been the case if such Covenant 
Defeasance had not occurred; (iv) no Default or Event of Default shall have 
occurred and be continuing on the date of such deposit (other than a Default 
or Event of Default resulting from the borrowing of funds to be applied to 
such deposit) or insofar as Events of Default from bankruptcy or insolvency 
events are concerned, at any time in the period ending on the 91st day after 
the date of deposit; (v) such Legal Defeasance or Covenant Defeasance will 
not result in a breach or violation of, or constitute a default under any 
material agreement or instrument (other than the Indenture) to which the 
Company or any of its Subsidiaries is a party or by which the Company or any 
of its Subsidiaries is bound; (vi) the Company must have delivered to the 
Trustee an opinion of counsel to the effect that after the 91st day following 
the deposit, the trust funds will not be subject to the effect of any 
applicable bankruptcy, insolvency, reorganization or similar laws affecting 
creditors' rights generally; (vii) the Company must deliver to the Trustee an 
Officers' Certificate stating that the deposit was not made by the Company 
with the intent of preferring the Holders of Notes over the other creditors 
of the Company with the intent of defeating, hindering, delaying or 
defrauding creditors of the Company or others; and (viii) the Company must 
deliver to the Trustee an Officers' Certificate and an opinion of counsel, 
each stating that all conditions precedent provided for relating to the Legal 
Defeasance or the Covenant Defeasance have been complied with. 

TRANSFER AND EXCHANGE 

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

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

                                       87
<PAGE>
AMENDMENT, SUPPLEMENT AND WAIVER 

   Except as provided in the next two succeeding paragraphs, 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 Notes then outstanding 
(including, without limitation, consents obtained in connection with a 
purchase of, or tender offer or exchange offer for, 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 (including consents obtained in connection with a 
tender offer or exchange offer for Notes). 

   Without the consent of each Holder affected, an amendment or waiver may 
not (with respect to any Notes held by a non-consenting Holder): (i) reduce 
the principal amount of Notes whose Holders must consent to an amendment, 
supplement or waiver, (ii) reduce the principal of or change the fixed 
maturity of any Note or alter the provisions with respect to the redemption 
of the Notes (other than provisions relating to the covenants described above 
under the caption "--Repurchase at the Option of Holders"), (iii) reduce the 
rate of or change the time for payment of interest on any Note, (iv) waive a 
Default or Event of Default in the payment of principal of or premium, 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 Notes and a waiver of the payment default that resulted from such 
acceleration), (v) make any Note payable in money other than that stated in 
the Notes, (vi) make any change in the provisions of the Indenture relating 
to waivers of past Defaults or the rights of Holders of Notes to receive 
payments of principal of or premium, if any, or interest on the Notes, (vii) 
waive a redemption payment with respect to any Note (other than a payment 
required by one of the covenants described above under the caption 
"--Repurchase at the Option of Holders") or (viii) make any change in the 
foregoing amendment and waiver provisions. In addition, any amendment to the 
provisions of Article 10 of the Indenture (which relates to subordination) 
will require the 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. 

   Notwithstanding the foregoing, without the consent of any Holder of Notes, 
the Company and the Trustee may amend or supplement the Indenture or the 
Notes 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 Notes 
in the case of a merger or consolidation, to make any change that would 
provide any additional rights or benefits to the Holders of Notes or that 
does not adversely affect the legal rights under the Indenture of any such 
Holder, or to comply with requirements of the Commission in order to effect 
or maintain the qualification of the Indenture under the Trust Indenture Act. 

CONCERNING THE TRUSTEE 

   The Indenture contains certain limitations on the rights of the Trustee, 
should it become a creditor of the Company, to obtain payment of claims in 
certain cases, or to realize on certain property received in respect of any 
such claim as security or otherwise. The Trustee will be permitted to engage 
in other transactions; however, if it acquires any conflicting interest it 
must eliminate such conflict within 90 days, apply to the Commission for 
permission to continue or resign. 

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

                   UNITED STATES FEDERAL TAX CONSIDERATIONS 

   Based on the advice of Simpson Thacher & Bartlett, the following summary 
accurately describes the material U.S. federal income tax consequences that 
may be relevant to the purchase, ownership and disposition of the Notes as of 
the date hereof by U.S. Holders as described below. Except where noted, it 
deals only with Notes held as capital assets by initial purchasers that 
purchase the Notes at their issue price and does not deal with special 
situations, such as those of dealers in securities or currencies, financial 
institutions, tax-exempt entities, life insurance companies, persons holding 
Notes as a part of a hedging constructive sale or conversion transaction or a 
straddle or holders of Notes whose "functional currency" is not the U.S. 
dollar. Furthermore, the discussion below is based upon the provisions of the 
Internal Revenue Code of 1986, as amended (the "Code"), and regulations, 
rulings and judicial decisions thereunder as of the date hereof, and such 
authorities may be repealed, revoked or modified so as to result in federal 
income tax consequences different from those discussed below. In addition, 
except as otherwise indicated, the following does not consider the effect of 
any applicable foreign, state, local or other tax laws or estate or gift tax 
considerations. PERSONS CONSIDERING THE PURCHASE, OWNERSHIP OR DISPOSITION OF 
NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL INCOME TAX 
CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS, AS WELL AS ANY 
CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION. 

STATED INTEREST ON NOTES 

   It is expected that the Notes will not be issued with original issue 
discount, therefore, interest on a Note will generally be taxable to a U.S. 
Holder as ordinary income from domestic sources at the time it is paid or 
accrued in accordance with the U.S. Holder's method of accounting for tax 
purposes. As used herein, a "U.S. Holder" means a holder of a Note that is 
(i) a citizen or resident of the United States, (ii) a corporation or 
partnership created or organized in or under the laws of the United States or 
any political subdivision thereof, (iii) an estate the income of which is 
subject to U.S. federal income taxation regardless of its source, or (iv) a 
trust which is subject to the supervision of a court within the United States 
and the control of one or more U.S. persons as described in Section 
7701(a)(30) of the Code. A "Non-U.S. Holder" is a holder of a Note that is 
not a U.S. Holder. 

SALE, EXCHANGE AND RETIREMENT OF NOTES 

   A U.S. Holder's tax basis in a Note will, in general, be the U.S. Holder's 
cost therefor. Upon the sale, exchange, retirement or other disposition of a 
Note, a U.S. Holder will recognize gain or loss equal to the difference 
between the amount realized upon the sale, exchange, retirement or other 
disposition and the tax basis of the Note. Such gain or loss will be capital 
gain or loss and will be long-term capital gain or loss if at the time of 
sale, exchange, retirement or other disposition the Note has been held for 
more than one year. Under recently enacted legislation, capital gains of 
individuals derived in respect of capital assets held for more than one year 
are eligible for reduced rates of taxation which may vary depending upon the 
holding period of such capital assets. Prospective investors should consult 
their own tax advisors with respect to the tax consequences of the new 
legislation. The deductibility of capital losses is subject to limitations. 

NON-U.S. HOLDERS 

   Under present U.S. federal income and estate tax law, and subject to the 
discussion below concerning backup withholding: 

     (a) no withholding of U.S. federal income tax will be required with 
    respect to the payment by the Company or any paying agent of principal, 
    premium, if any, or interest on, if any, in respect of a Note owned by a 
    Non-U.S. Holder (the "Portfolio Interest Exception"), provided (i) that 
    the beneficial owner does not actually or constructively own 10% or more 
    of the total combined voting power of all classes of stock of the Company 
    entitled to vote within the meaning of section 871(h)(3) of the Code and 
    the regulations thereunder, (ii) the beneficial owner is not a controlled 
    foreign corporation that is related to the Company through stock 
    ownership, (iii) the beneficial owner is not a bank whose receipt of 
    interest on a Note is described in section 881(c)(3)(A) of the Code and 
    (iv) the beneficial owner satisfies the statement requirement (described 
    generally below) set forth in section 871(h) and section 881(c) of the 
    Code and the regulations thereunder. 

                                       98
<PAGE>
     (b) no withholding of U.S. federal income tax will be required with 
    respect to any gain or income realized by a Non-U.S. Holder upon the sale, 
    exchange, retirement or other disposition of a Note; and 

     (c) a Note beneficially owned by an individual who at the time of death 
    is a Non-U.S. Holder will not be subject to U.S. federal estate tax as a 
    result of such individual's death, provided that such individual does not 
    actually or constructively own 10% or more of the total combined voting 
    power of all classes of stock of the Company entitled to vote within the 
    meaning of section 871(h)(3) of the Code and provided that the interest 
    payments with respect to such Note would not have been, if received at the 
    time of such individual's death, effectively connected with the conduct of 
    a U.S. trade or business by such individual. 

   To satisfy the requirement referred to in (a)(iv) above, the beneficial 
owner of such Note, or a financial institution holding the Note on behalf of 
such owner, must provide, in accordance with specified procedures, a paying 
agent of the Company with a statement to the effect that the beneficial owner 
is not a U.S. person. Currently, these requirements will be met if (i) the 
beneficial owner provides his name and address, and certifies, under 
penalties of perjury, that he is not a U.S. person (which certification may 
be made on an IRS Form W-8 (or successor form)) or (ii) a financial 
institution holding the Note on behalf of the beneficial owner certifies, 
under penalties of perjury, that such statement has been received by it and 
furnishes a paying agent with a copy thereof. Under recently finalized 
Treasury regulations (the "Final Regulations"), the statement requirement 
referred to in (a)(iv) above may also be satisfied with other documentary 
evidence for interest paid after December 31, 1999 with respect to an 
offshore account or through certain foreign intermediaries. 

   If a Non-U.S. Holder cannot satisfy the requirements of the Portfolio 
Interest Exception described in (a) above, payments on a Note made to such 
Non-U.S. Holder will be subject to a 30% withholding tax unless the 
beneficial owner of the Note provides the Company or its paying agent, as the 
case may be, with a properly executed (i) IRS Form 1001 (or successor form) 
claiming an exemption from withholding under the benefit of a tax treaty or 
(ii) IRS Form 4224 (or successor form) stating that interest paid on the Note 
is not subject to withholding tax because it is effectively connected with 
the beneficial owner's conduct of a trade or business in the United States. 
Under the Final Regulations, Non-U.S. Holders will generally be required to 
provide IRS Form W-8 in lieu of IRS Form 1001 and IRS Form 4224, although 
alternative documentation may be applicable in certain situations. 

   If a Non-U.S. Holder is engaged in a trade or business in the United 
States and payment on a Note is effectively connected with the conduct of 
such trade or business, the Non-U.S. Holder, although exempt from the 
withholding tax discussed above, will be subject to U.S. federal income tax 
on such payment on a net income basis in the same manner as if it were a U.S. 
Holder. In addition, if such holder is a foreign corporation, it may be 
subject to a branch profits tax equal to 30% of its effectively connected 
earnings and profits for the taxable year, subject to adjustments. For this 
purpose, such payment on a Note will be included in such foreign 
corporation's earnings and profits. 

   Any gain or income realized upon the sale, exchange, retirement or other 
disposition of a Note generally will not be subject to U.S. federal income 
tax unless (i) such gain or income is effectively connected with a trade or 
business in the United States of the Non-U.S. Holder, or (ii) in the case of 
a Non-U.S. Holder who is an individual, such individual is present in the 
United States for 183 days or more in the taxable year of such sale, 
exchange, retirement or other disposition, and certain other conditions are 
met. 

INFORMATION REPORTING AND BACKUP WITHHOLDING 

   In general, information reporting requirements will apply to payments on a 
Note and to the proceeds of sale of a Note made to U.S. Holders other than 
certain exempt recipients (such as corporations). A 31% backup withholding 
tax will apply to such payments if the U.S. Holder fails to provide a 
taxpayer identification number or certification of foreign or other exempt 
status or fails to report in full dividend and interest income. 

                                       99
<PAGE>
   No information reporting or backup withholding will be required with 
respect to payments made by the Company or any paying agent to Non-U.S. 
Holders if a statement described in (a)(iv) under "--Non-U.S. Holders" has 
been received and the payor does not have actual knowledge that the 
beneficial owner is a U.S. person. 

   In addition, backup withholding and information reporting will not apply 
if payments on a Note are paid or collected by a foreign office of a 
custodian, nominee or other foreign agent on behalf of the beneficial owner 
of such Note, or if a foreign office of a broker (as defined in applicable 
Treasury regulations) pays the proceeds of the sale of a Note to the owner 
thereof. If, however, such nominee, custodian, agent or broker is, for U.S. 
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 certain 
periods 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 
custodian, nominee, agent or broker has documentary evidence in its records 
that the beneficial owner is not a U.S. person and certain other conditions 
are met or (ii) the beneficial owner otherwise establishes an exemption. 

   Payments on a Note paid to the beneficial owner of a Note by a U.S. office 
of a custodian, nominee or agent, or the payment by the U.S. office of a 
broker of the proceeds of sale of a Note, will be subject to both backup 
withholding and information reporting unless the beneficial owner provides 
the statement referred to in (a)(iv) above and the payor does not have actual 
knowledge that the beneficial owner is a U.S. person or otherwise establishes 
an exemption. 

   Any amounts withheld under the backup withholding rules will 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.

</TABLE>

   The Underwriting Agreement provides that the obligations of the 
Underwriters to purchase the Notes are subject to the approval of certain 
legal matters by their counsel and to certain conditions, and that if any 
Notes are purchased by the Underwriters pursuant to the Underwriting 
Agreement, all of the Notes agreed to be purchased by the Underwriters 
pursuant to the Underwriting Agreement must be so purchased. 

   In the Underwriting Agreement, L-3 Communications has agreed to indemnify 
the Underwriters against certain liabilities, including liabilities under the 
Securities Act, or to contribute to payments that the Underwriters may be 
required to make in respect thereof. 

   In order to facilitate the Notes Offering, the Underwriters may engage in 
transactions that stabilize, maintain, or otherwise affect the price of the 
Notes. Specifically, the Underwriters may overallot in connection with the 
Notes Offering, creating a short position in the Notes for their own account. 
In addition, to cover overallotments or to stabilize the price of the Notes, 
the Underwriters may bid for and purchase Notes in the open market. Any of 
these activities may stabilize or maintain the market price of the Notes 
above independent market levels. 

   Lehman Brothers Inc. has provided investment banking, financial advisor 
and other services to the Company, for which services Lehman Brothers Inc. 
has received fees. In addition, Lehman Brothers Inc. is acting as lead 
underwriter for the concurrent Common Stock Offering, and Lehman Brothers 
Commercial Paper Inc., an affiliate of Lehman Brothers Inc., is the Arranger 
and Syndication Agent under the Senior Credit Facilities. After the 
completion of the Common Stock Offering and assuming that the Underwriters' 
over-allotment option is exercised, the Lehman Partnership will beneficially 
own 36.6% of the outstanding capital stock of Holdings. By virtue of such 
ownership, the Lehman Partnership will be able to significantly influence the 
business and affairs of the Company with respect to matters requiring 
stockholder approval. See "Management -- Directors and Executive Officers" 
and "Ownership of Capital Stock". 

   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 Notes Offering is being conducted 
in accordance with Rule 2720, which provides that, among other things, when 
an NASD member participates in the underwriting of an affiliate's debt 
securities, the yield at which such debt securities is to be distributed to 
the public can be no lower than that recommended by a "qualified independent 
underwriter" meeting certain standards ("QIU"). In accordance with this 
requirement, C.E. Unterberg, Towbin has assumed the responsibilities of 
acting as QIU and will recommend a yield for the Notes in compliance with the 
requirements of Rule 2720. In connection with the Notes Offering, C.E. 
Unterberg, Towbin is performing due diligence investigations and reviewing 
and participating in the preparation of this Prospectus and the Registration 
Statement of which this Prospectus forms a part. C.E. Unterberg, Towbin will 
receive $10,000 as compensation for its services as QIU. 

   Bank of America NT&SA, an affiliate of BancAmerica Robertson Stephens, 
acts as the Administrative Agent and a lender under the Senior Credit 
Facilities. See "Description of Certain Indebtedness -- Senior Credit 
Facilities". Bank of America NT&SA and Lehman Brothers Commercial Paper Inc. 
will receive a portion of the net proceeds of the Offerings in repayment of 
indebtedness outstanding under the Senior Credit Facilities.

                  NOTES TO UNAUDITED CONDENSED CONSOLIDATED 
                       (COMBINED) FINANCIAL STATEMENTS 
                            (DOLLARS IN THOUSANDS) 

1. BASIS OF PRESENTATION 

   The accompanying condensed consolidated (combined) financial statements 
include the assets, liabilities and results of operations of L-3 
Communications Corporation, the successor company ("L-3" or the "Company") 
following the change in ownership (see Note 2) effective as of April 1, 1997. 
Prior to April 1, 1997, the statements comprise substantially all of the 
assets and certain liabilities 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, 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' 
results of operations and cash flows included in Lockheed Martin's historical 
financial statements. Significant inter-company and inter-business 
transactions and balances have been eliminated. 

   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 Regulations 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. All significant intercompany 
balances and transactions have been eliminated. 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 notes to these Unaudited Condensed Consolidated 
Financial Statements as of March 31, 1998 and Company's Consolidated 
(Combined) Financial Statements as of December 31, 1997 and notes thereto. 

2. CHANGE IN OWNERSHIP TRANSACTION 

   L-3 was formed on April 8, 1997, and is a wholly-owned subsidiary of L-3 
Communications Holdings, Inc. ("Holdings"). Holdings and L-3 Communications 
were 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. The Company was capitalized with 
an equity contribution from Holdings of $125,000. 

   On March 28, 1997, Lanza, LaPenta, the Lehman Partnership, Holdings, 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"). Pursuant to the L-3 Acquisition Agreement on 
April 30, 1997 (closing date), Holdings acquired the Businesses from Lockheed 
Martin for $525,000, comprised of $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. Also pursuant to the Transaction Agreement, 
Lockheed Martin, on behalf and at the direction of Holdings, transferred the 
Businesses to the Company. The Acquisition was financed with the debt 
proceeds of $400,000 (see Note 5) and capital contributions of $125,000 from 
Holdings, including the $45,000 retained by Lockheed Martin.

                  NOTES TO UNAUDITED CONDENSED CONSOLIDATED 
                       (COMBINED) FINANCIAL STATEMENTS 
                            (DOLLARS IN THOUSANDS) 

   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 production of mission 
communication systems for track vehicles, for which the Company received a 
cash payment of $12,176. The assets and liabilities recorded in connection 
with the L-3 Acquisition 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 
EITF 88-16 were applied in connection with the purchase price allocation, 
which resulted in recording net assets acquired at 34.9% of Lockheed Martin's 
carrying values in the Businesses and 65.1% at fair value, and the 
recognition of a deemed distribution of $9,000. 

3. ACQUISITIONS 

   On March 30, 1998 the Company purchased the assets of the Ocean Systems 
business ("Ocean Systems") of Allied Signal, 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 in cash, 
subject to adjustment based upon closing net assets. On January 13, 1998, the 
Company purchased all of the stock of Southern California Microwave, Inc. 
("SCM") for $4,600 subject to adjustment based on closing net assets, and 
additional consideration based on post-acquisition performance of SCM. 

   The Company has financed the acquisitions using its cash on hand and 
available borrowings under its Revolving Credit Facility. The Ocean Systems, 
ILEX, STS and SCM acquisitions have been accounted for as purchase business 
combinations and are included in the Company's results of operation from 
their effective dates of March 31, 1998, February 1, 1998, February 1, 1998 
and January 1, 1998, respectively. 

   The assets and liabilities recorded in connection with the purchase price 
allocations for the acquisitions of Ocean Systems, ILEX, STS and SCM are 
based upon preliminary estimates. Actual adjustments will be based on final 
appraisals and other analyses of fair values which are in process and the 
final purchase prices. Management does not expect that differences between 
the preliminary and final 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 preliminary purchase price 
allocations for the acquisitions of Ocean Systems, ILEX, STS and SCM were 
$139,901 and $72,093, $58,349 and $4,238, $33,956 and $6,624, and $5,088 and 
$251, respectively. 

   Had the L-3 Acquisition and the Ocean Systems, ILEX and STS acquisitions 
occurred on January 1, 1997, the unaudited pro forma sales, net loss and loss 
per share for the three months ended March 31, 1998 and 1997 would have been 
$207,300, $(100) and $(0.00) and $189,200, $(7,300) and $(0.29), 
respectively. The pro forma results are based on various assumptions and are 
not necessarily indicative of what would have occurred had the acquisitions 
been consummated on January 1, 1997.

</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"). 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 in the 
Senior Credit Facilities, otherwise required, and permit the incurrence of up 
to an additional $150,000 of subordinated debt. The Revolving Credit Facility 
expires in 2003 and is available for ongoing working capital and letter of 
credit needs. Approximately $114,400 of the Revolving Credit Facility is 
available at March 31, 1998 reflecting $67,800 of borrowings and letters of 
credit of $17,800 drawn against the Revolving Credit Facility of $200,000. 

   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 March 31, 1998, 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 March 31, 1998, and that the maximum allowable debt ratio, as 
defined therein, 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 therein, be at least 1.85 for the quarter ended 
March 31, 1998, and thereafter increasing the interest coverage ratio, as 
defined therein, to at least 3.10 for any fiscal quarters ended after June 
30, 2002. At March 31, 1998, the Company was in compliance with these 
covenants. 

   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.

                            (DOLLARS IN THOUSANDS) 

   In February 1998, the Company filed a registration statement with the 
Securities and Exchange Commission ("SEC") for the sale of $150,000 aggregate 
principal amount of Senior Subordinated Notes due 2008 (the "Notes 
Offering"), and concurrently with the Notes Offering, Holdings filed a 
registration statement with the SEC for the sale of 5.5 million shares of 
common stock. 

6. STOCK OPTIONS 

   On March 2, 1998, Messrs. Lanza and LaPenta each exercised options to 
purchase 228,571 shares of Holdings' Class A Common Stock. The options were 
granted on April 30, 1997 at an exercise price of $6.47. Holdings contributed 
aggregate proceeds of $2,958 for such exercise of stock options to the 
Company, which the Company has recorded to additional paid-in capital in the 
accompanying balance sheet.

   Supplemental disclosures to the Condensed Consolidated (Combined) 
Statement of Cash Flows are as follows:

</TABLE>

   During the quarter ended March 31, 1998, the Company credited a current 
income tax benefit of $451 directly to shareholders' equity related to the 
tax benefit from the exercise of stock options. 

8. ACCOUNTING POLICIES 

   On January 1, 1998, the Company adopted Statement of Financial Accounting 
Standards ("SFAS") No. 130, "Reporting Comprehensive Income." SFAS No. 130 
establishes standards for reporting and display of comprehensive income and 
its components (revenues, expenses, gains and losses) in a full set of 
general purpose financial statements. For the three months ended March 31, 
1998 and 1997, there were no differences between net income and comprehensive 
income. 

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 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 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, 
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 investigate 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.

                        REPORT OF INDEPENDENT AUDITORS 

To the Board of Directors of 
 L-3 Communications Corporation: 

   We have audited the accompanying (i) consolidated balance sheet of L-3 
Communications Corporation and subsidiaries (the "Company") as of December 
31, 1997, and the related consolidated statements of operations, changes in 
shareholders' equity, and cash flows for the nine months then ended, (ii) the 
combined statements of operations and cash flows of the Predecessor Company, 
as defined in Note 1 to the 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 period 
ended December 31, 1995, in conformity with generally accepted accounting 
principles.

            NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS 
                            (Dollars in thousands) 

1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS 

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

   The Company is a 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 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 
and various cost controls, and include standard provisions for termination 
for the convenience of the U.S. Government. Multi-year U.S. Government 
contracts and related orders are subject to cancellation if funds for 
contract performance for any subsequent year become unavailable. Foreign 
government contracts generally include comparable provisions relating to 
termination for the convenience of the government. 

2. CHANGE IN OWNERSHIP TRANSACTION 

   Holdings and L-3 were 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. The 
Company was capitalized with an equity contribution from Holdings of 
$125,000. 

   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 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 

                              F-19           
<PAGE>
                        L-3 COMMUNICATIONS CORPORATION 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
                            (Dollars in thousands) 

assumption by the Company of Lockheed Martin's rights and obligations under a 
contract for the production of mission communication systems for track 
vehicles, for which the Company received cash of $12,176. 

   In connection with the L-3 Acquisition Agreement, Holdings and 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 Communication Systems 
- -- East (formerly known as Communication 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 have been adjusted to (a) include the operations of the Loral Acquired 
Businesses from January 1, 1996 (Note 3) and (b) exclude the operations of 
the Hycor business net assets held for sale from January 1, 1996 (Note 6). 

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

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

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

                        L-3 COMMUNICATIONS CORPORATION 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
                            (Dollars in thousands) 

   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 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 

                              F-21           
<PAGE>
                        L-3 COMMUNICATIONS CORPORATION 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
                            (Dollars in thousands) 

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 
asset 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 the Company's 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 Holdings common 
stock at the date of grant, thereby resulting in no recognition of 
compensation expense by the Company. The Company has adopted the disclosure 
- -only provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" 
("SFAS 123"). 

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

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

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

   ACCOUNTING PRONOUNCEMENTS: In June 1997, the FASB issued Statement of 
Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive 
Income" and SFAS No. 131, "Disclosure about Segments of an Enterprise and 
Related Information." SFAS No. 130 establishes standards for reporting and 
display of comprehensive income and its components (revenues, expenses, gains 
and losses) in full set general purpose financial statements. SFAS No. 131 
establishes accounting standards for the way that public business enterprises 
report selected information about operating segments and requires that those 
enterprises report selected information about operating segments in interim 
financial reports issued to shareholders. In February 1998, the FASB issued 
SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement 
Benefits." SFAS No. 132 revises employers' disclosures about pension and 
other postretirement benefits plans. It does not change the measurement or 
recognition of those plans. It standardizes the disclosure requirements for 
pensions and other postretirement benefits to the extent practicable, 
requires additional information on changes in the benefit obligations and 
fair values of plan assets that will facilitate financial analysis, and 
eliminates certain disclosures that are no longer as useful as they were when 
SFAS No. 87 "Employers' Accounting for Pensions", SFAS No. 88 "Employers' 
Accounting for Settlements and Curtailments of Defined Benefit Pension Plans 
and for Termination Benefits" and SFAS No. 106 "Employers' Accounting for 
Postretirement Benefits Other Than Pensions" were issued. SFAS No. 132 
suggests combined formats for presentation of pension and other 
postretirement benefits disclosures. SFAS No. 130 and 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 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. 
129, "Disclosure of Information about Capital Structure" ("SFAS 129"). 

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

4. PREDECESSOR COMPANY ACQUISITION 

   Effective April 1, 1996, Lockheed Martin acquired substantially all the 
assets and liabilities of the defense businesses of Loral, including the 
Wideband Systems Division and the Products Group which are included in the 
Businesses. The acquisition of the Wideband Systems Division and Products 
Group businesses (the "Loral Acquired Businesses") has been accounted for as 
a purchase by Lockheed Martin Communications Systems -- Camden Division 
("Division"). The acquisition has been reflected in the financial statements 
based on the purchase price allocated to those acquired businesses by 
Lockheed Martin. The assets and liabilities recorded in connection with the 
purchase price allocation were $401,000 and $113,200, respectively. As such, 
the accompanying condensed 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.

   The U.S. Government has title to or a secured interest in, inventory to 
which progress payments are applied. Unbilled contract receivables represent 
accumulated costs and profits earned but not yet billed to customers. The 
Company believes that substantially all such amounts will be billed and 
collected within one year.

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.

</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 a rate related to (i) the higher of federal 
funds rate plus 0.50% per annum or the reference rate published by Bank of 
America NT&SA or (ii) LIBOR. At December 31, 1997, such interest rates, based 
on various maturities, ranged from 7.625% to 8.625%. Interest payments vary 
in accordance with the type of borrowing and are made at a minimum every 
three months. The Revolving Credit Facility expires in 2003 and is available 
for ongoing working capital and letter of credit needs. The Term Loans mature 
in installments until the final maturity date in 2006. Approximately $93,428 
of the Revolving Credit Facility is available at December 31, 1997 reflecting 
letters of credit of $6,572 drawn 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

                            (Dollars in thousands) 

Notes and the holders of the 1997 Notes received registered securities. The 
1997 Notes are redeemable at the option of the Company, in whole or in part, 
at any time on or after May 1, 2002, at various redemption prices plus 
accrued and unpaid interest to the applicable redemption date. In addition, 
prior to May 1, 2000, the Company may redeem up to 35% of the aggregate 
principal amount of 1997 Notes at a redemption price of 109.375% of the 
principal amount thereof, plus accrued and unpaid interest to the redemption 
date with the net cash proceeds of one or more equity offerings by Holdings 
that are contributed to the Company as common equity capital. 

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

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

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

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

9. PREDECESSOR COMPANY'S INTEREST EXPENSE 

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

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

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:

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

11. NONCASH COMPENSATION CHARGE 

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

12. INCOME TAXES

   Pretax income of the Company for the nine months ended December 31, 1997

   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.

13. STOCK OPTIONS 

THE COMPANY 

   Holdings sponsors an option plan for key employees, pursuant to which 
options to purchase up to 3,255,815 shares of 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 the Company 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 vesting 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 the Company. 

   Pro forma information regarding net earnings as required by SFAS 123 has 
been determined as if the Company 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's 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.

14. COMMITMENTS AND CONTINGENCIES 

THE COMPANY 

   The Company and Predecessor Company leases 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:

</TABLE>

   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 have 
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 

                              F-31           
<PAGE>
                        L-3 COMMUNICATIONS CORPORATION 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
                            (Dollars in thousands) 

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 the Company's financial 
condition or upon the results of its operations. 

   Management continually assesses the Company's obligations with respect to 
applicable environmental protection laws. While it is difficult to determine 
the timing and ultimate cost to be incurred by the Company in order to comply 
with these laws, based upon available internal and external assessments, with 
respect to those environmental loss contingencies of which management is 
aware, the Company believes that even without considering potential insurance 
recoveries, if any, there are no environmental loss contingencies that, 
individually or in the aggregate, would be material to the Company's results 
of operations. The Company accrues for these contingencies when it is 
probable that a liability has been incurred and the amount of the loss can be 
reasonably estimated. 

   The Company and the Predecessor Company have been periodically subject to 
litigation, claims or assessments and various contingent liabilities 
(including environmental matters) incidental to its business. With respect to 
those investigative actions, items of litigation, claims or assessments of 
which they are aware, management of the Company is of the opinion that the 
probability is remote that, after taking into account certain provisions that 
have been made with respect to these matters, the ultimate resolution of any 
such investigative actions, items of litigation, claims or assessments will 
have a material adverse effect on the financial position or results of 
operations of the Company and the Predecessor Company. 

15. PENSIONS AND OTHER EMPLOYEE BENEFITS 

THE COMPANY 

   PENSIONS: Holdings and the Company maintain a number of pension plans, 
both contributory and noncontributory, covering certain employees. 
Eligibility for participation in these plans varies and benefits are 
generally based on members' compensation and years of service. The Company's 
funding policy is generally to contribute in accordance with cost accounting 
standards that affect government contractors, subject to the Internal Revenue 
Code and regulations thereon. Plan assets are invested primarily in U.S. 
government and agency obligations and listed stocks and bonds. 

   Pension expense for the nine months ended December 31, 1997 includes the 
following components:

</TABLE>

   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.

   Actuarial assumptions used in determining the December 31, 1997 
accumulated post-retirement benefit obligation include a discount rate of 
7.25%, an average rate of compensation increase of 5.0% and an assumed health 
care cost trend rate of 6.5% in 1997 decreasing gradually to a rate of 4.5% 
by the year 2001. The discount rate used at April 1, 1997 was 7.50%. The 
other assumptions did not change from April 1, 1997. Increasing the assumed 
health care cost trend rate by 1% would change the accumulated 
post-retirement benefits obligation at December 31, 1997 by approximately 
$2,218 and the aggregate service and interest cost components for the nine 
months ended December 31, 1997 by approximately $81 and $113, respectively. 

   EMPLOYEE SAVINGS PLAN: Under its various employee savings plans, the 
Company matches the contributions of participating employees up to a 
designated level. The extent of the match, vesting terms and the form of the 
matching contribution vary among the plans. Under these plans, the Company's 
matching contributions, in cash, for the nine months ended December 31, 1997 
was $3,742. 

THE PREDECESSOR COMPANY 

   Certain of the Businesses for the Predecessor Company participated in 
various Lockheed Martin-sponsored pension plans covering certain employees. 
Eligibility for participation in these plans varies, and benefits are 
generally based on members' compensation and years of service. Lockheed 
Martin's funding policy was generally to contribute in accordance with cost 
accounting standards that affect government contractors, subject to the 
Internal Revenue Code and regulations. Since the aforementioned pension 
arrangements are part of certain Lockheed Martin defined benefit plans, no 
separate actuarial data is available for the portion allocable to the 
Businesses. Therefore, no liabilities or assets are reflected in the 
accompanying combined financial statements of the Predecessor Company as of 
December 31, 1996. The Businesses have been allocated pension costs based 
upon participant employee headcount. Net pension expense included in the 
accompanying combined financial statements of the Predecessor Company was 
$1,848 for the three months ended March 31, 1997, and $7,027 and $4,134, for 
the years ended December 31, 1996 and 1995, respectively. 

   In addition to participating in Lockheed Martin-sponsored pension plans, 
certain of the Businesses of the Predecessor Company provided varying levels 
of health care and life insurance benefits for retired

employees and dependents. Participants were eligible for these benefits when 
they retired from active service and met the pension plan eligibility 
requirements. These benefits are funded primarily on a pay-as-you-go basis 
with the retiree generally paying a portion of the cost through 
contributions, deductibles and coinsurance provisions. Since the 
aforementioned postretirement benefits are part of certain Lockheed Martin 
postretirement arrangements, no separate actuarial data is available for the 
portion allocable to the Businesses. Accordingly, no liability is reflected 
in the accompanying combined financial statements as of combined December 31, 
1996 and 1995. The Businesses have been allocated postretirement benefits 
cost based on participant employee headcount. Postretirement benefit costs 
included in the accompanying combined financial statements was $616 for the 
three months ended March 31, 1997 and $2,787 and $2,124 for the years ended 
December 31, 1996 and 1995, respectively. Under various employee savings 
plans sponsored by Lockheed Martin, the Predecessor Company matched 
contributions of participating employees up to a designated level. Under 
these plans the matching contributions for the three months ended March 31, 
1997 and for the years ended December 31, 1996 and 1995 were $1,241, $3,940 
and $1,478, respectively.

ended March 31, 1997 and $70,658 and $25,874 for the years ended December 31, 
1996 and 1995, respectively. Included in Contracts in Process are receivables 
from Lockheed Martin and its affiliates of $8,846 and $10,924 at December 31, 
1997 and 1996, respectively. 

   Lockheed Martin provides the Company information systems and other 
services and previously provided similar services to the Predecessor Company 
for which the Company and the Predecessor Company was charged $13,690, 
$4,210, $20,901 and $20,508 for the nine months ended December 31, 1997, the 
three months ended March 31, 1997 and the years ended December 31, 1996 and 
1995, respectively. 

   The Predecessor Company relied on Lockheed Martin for certain services, 
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 to these services have been allocated to the Businesses, the combined 
financial position, results of operations and cash flows presented in the 
accompanying combined financial statements would not be the same had the 
Businesses been independent entities. 

   The amount of allocated corporate expenses to the Predecessor Company and 
reflected in these combined financial statements was estimated based 
primarily on an allocation methodology prescribed by government regulations 
pertaining to government contractors. Allocated costs to the Businesses were 
$5,208 for the three months ended March 31, 1997, and $10,057 and $2,964 for 
the years ended December 31, 1996 and 1995, respectively.

                        REPORT OF INDEPENDENT AUDITORS 

Board of Directors of 
 L-3 Communications Corporation: 

   We have audited the accompanying combined statements of operations and 
cash flows for the Loral Acquired Businesses as defined in Note 1 (the 
"Businesses") for the three months ended March 31, 1996 and the year ended 
December 31, 1995. These financial statements are the responsibility of the 
Businesses' management. Our responsibility is to express an opinion on these 
financial statements based on our audits. 

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

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the combined results of the operations and cash 
flows of the Businesses for the three months ended March 31, 1996 and the 
year ended December 31, 1995, in conformity with generally accepted 
accounting principles.

1. BACKGROUND AND DESCRIPTION OF BUSINESS 

   On January 31, 1997, Lockheed Martin Corporation ("Lockheed Martin"), 
Lehman Brothers Holdings Inc. ("Lehman"), Frank C. Lanza ("Lanza") and Robert 
V. LaPenta ("LaPenta") entered into a Memorandum of Understanding ("MOU") 
regarding the transfer of certain businesses of Lockheed Martin to a newly 
formed corporation ("Newco") to be owned by Lockheed Martin, Lehman, Lanza 
and LaPenta. The businesses proposed to be transferred (the "Loral Acquired 
Businesses" or "Businesses") include Lockheed Martin's Wideband Systems 
Division and the Products Group, comprised of ten autonomous operations, all 
of which were acquired by Lockheed Martin effective April 1, 1996 as part of 
the acquisition by Lockheed Martin of the defense electronics business of 
Loral Corporation ("Loral"). Also included in the transaction is the 
acquisition of a semiconductor product line of another business and certain 
leasehold improvements in New York City. 

   The Businesses are leading suppliers of sophisticated secure communication 
systems, microwave communication components, avionic and instrumentation 
products and other products and services to major aerospace and defense 
contractors as well as the U.S. Government. The Businesses operate primarily 
in one industry segment, communication systems and products. 

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

   The decline in the U.S. defense budget since the mid 1980s has resulted in 
program delays, cancellations and scope reductions for defense contractors in 
general. These events may or may not have an effect on the Businesses' 
programs; however, in the event that expenditures for products of the type 
manufactured by the Businesses are reduced, and not offset by greater foreign 
sales or other new programs or products, or acquisitions, there may be a 
reduction in the volume of contracts or subcontracts awarded to the 
Businesses. 

   The Businesses' operations, as presented herein, include allocations and 
estimates of certain expenses of Loral based upon estimates of services 
performed by Loral that management of the Businesses believe are reasonable. 
Such services include treasury, cash management, employee benefits, taxes, 
risk management, internal audit and general corporate services. Accordingly, 
the results of operations and cash flows as presented herein may not be the 
same as would have occurred had the Businesses been independent entities. 

2. BASIS OF PRESENTATION 

BASIS OF COMBINATION 

   The accompanying combined financial statements reflect the Businesses' 
assets, liabilities and operations included in Loral Corporation's historical 
financial statements that will be transferred to Newco. All significant 
intercompany transactions and amounts have been eliminated. The combined 
financial statements do not include the operations of telecommunications 
switch product line which will not be transferred and was exited in 1995. 
Also, the assets and operations of the semiconductor product line and certain 
other facilities which are not material to the Businesses have been excluded 
from the financial statements.

                            (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-42           
<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.

5. OPERATING EXPENSES 

   The following expenses have been included in the statements of operations:

</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

11. RELATED PARTY TRANSACTIONS 

   The Businesses had a number of transactions with Loral and its affiliates. 
Management believes that the arrangements are as favorable to the Businesses 
as could be obtained from unaffiliated parties. The following describe the 
related party transactions. 

   Loral allocated certain operational, administrative, legal and other 
services to the Businesses. Costs allocated to the Businesses were $1,827 and 
$6,535 for the three months ended March 31, 1996 and the year ended December 
31, 1995, respectively. The Businesses sold products to Loral and its 
affiliates. Net sales to Loral were $14,840 for the three months ended March 
31, 1996 and were $54,600 in 1995. Net sales to Space Systems/Loral were 
$2,471 for the three months ended March 31, 1996 and were $4,596 in 1995. Net 
sales to K&F Industries were $1,173 for the three months ended March 31, 1996 
and were $2,415 in 1995.

                 SIX MONTHS ENDED DECEMBER 31, 1996 AND 1997 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

BASIS OF PRESENTATION 

   The accompanying unaudited financial statements include the operations of 
the Satellite Transmission Systems Division ("STS" or the "Division") of 
California Microwave, Inc. ("CMI" or the "Company"). The Division is a global 
satellite communication systems integrator providing hardware, software and 
services for turnkey projects to large commercial customers, principally 
domestic and foreign telephone companies and major common carriers and to the 
U.S. and foreign governments. 

   These financial statements are presented as if the Division had existed as 
an entity separate from CMI during the periods presented and include the 
historical assets, liabilities, sales and expenses that are directly related 
to the Division's operations. However, these financial statements are not 
necessarily indicative of the financial position and results of operations 
which would have occurred had the Division been an independent entity. 

   The accompanying unaudited condensed financial statements have been 
prepared in accordance with generally accepted accounting principles for 
interim financial information and Article 10 of Regulation S-X. Accordingly, 
they do not include all of the information and footnotes required by 
generally accepted accounting principles for complete financial statements. 
In the opinion of management, all adjustments (consisting of normal recurring 
accruals) considered necessary for a fair presentation have been included. 
Operating results for the six-month periods ended December 31, 1996 and 1997 
are not necessarily indicative of the results that may be expected for the 
years ended June 30, 1997 and 1998. For further information, refer to the 
financial statements and footnotes thereto included in the Division's 
financial statements for the year ended June 30, 1997. 

USE OF ESTIMATES; RISKS AND UNCERTAINTIES 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the amounts reported in the financial statements and 
accompanying notes. Significant estimates are used in determining the 
collectibility of accounts receivable, warranty costs, inventory realization, 
profitability on long-term contracts, restructuring reserves, recoverability 
of property, plant and equipment, and contingencies. Actual results could 
differ from estimates. 

INVENTORIES AND COST OF PRODUCTS SOLD 

   Inventories are recorded at the lower of cost or market. Project 
inventories are transferred to cost of products sold at the time revenue is 
recognized based on the estimated total manufacturing costs and total 
contract prices under each contract. Losses on contracts are recognized in 
full when the losses become determinable. The cost of other inventories is 
generally based on standard costs which approximate actual costs determined 
by the first-in, first-out method.

3. CORPORATE ALLOCATIONS 

   CMI allocates corporate expenses on a value-added basis to each division, 
which CMI believes results in a reasonable allocation of such costs. The 
accompanying financial statements reflect charges for general corporate 
administrative expenses incurred by CMI which amounted to approximately 
$832,000 and $793,000 for the six months ended December 31, 1996 and 1997, 
respectively. 

   No interest is allocated by CMI to the Division. 

   The Division is charged for its proportional share of CMI's self-insured 
medical plan. Such charges amounted to $1,015,000 and $732,000 for the six 
months ended December 31, 1996 and 1997, respectively. 

   In addition, there were direct charges from CMI as follows:

                            ====== ====== 
</TABLE>

   The Division believes that the direct charges from CMI were reasonable 
during the periods presented. 

4. RESTRUCTURING 

   During fiscal 1997, a comprehensive review of the Division's operations 
was performed, including a review of inventory levels, product development 
and migration plans and facility and personnel needs. It was determined to 
focus the Division on potentially higher margin products. This resulted in 
the write-down of certain inventories and the restructuring of the Division's 
operations. During the six month period ended December 31, 1996 inventory and 
other charges of $10,300,000, arising from this review, were included in cost 
of products sold. During February 1997, additional charges of $800,000 
relating to excess facilities and severance were recorded. There are no 
remaining cash outlays associated with the restructuring at December 31, 
1997.

5. OTHER 

   In November 1997, the Division recorded a $1 million charge to cost of 
sales relating to a contract with a customer in Sudan. The President of the 
United States imposed economic sanctions on Sudan which banned U.S. companies 
from doing business in Sudan and as a result, the Division could not continue 
to perform under the existing contract. Based upon this, the contract was 
terminated and the Division has been released from further performance 
requirements. 

   On December 19, 1997, L-3 Communications Corporation, an unrelated party, 
reached an agreement to purchase from CMI substantially all of the assets of 
the Division, and to assume certain of the liabilities of the Division, for 
approximately $27 million in cash. The final purchase price is subject to 
adjustment based on the net assets of the Division at the closing date of the 
transaction.

                        REPORT OF INDEPENDENT AUDITORS 

The Board of Directors 
California Microwave, Inc. 

   We have audited the accompanying balance sheets of the Satellite 
Transmission Systems Division of California Microwave, Inc. (the "Company") 
as of June 30, 1997 and 1996, and the related statements of operations and 
cash flows for each of the three years in the period ended June 30, 1997. 
These financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these financial 
statements based on our audit. 

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

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of the Satellite 
Transmission Systems Division of California Microwave, Inc., as of June 30, 
1997 and 1996, and the results of its operations and its cash flows for each 
of the three years in the period ended June 30, 1997 in conformity with 
generally accepted accounting principles.

                        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. The intangible

                  NOTES TO FINANCIAL STATEMENTS (CONTINUED) 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  (Continued) 
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

   The Division believes that the direct charges from CMI were reasonable

11. RELATED PARTY TRANSACTIONS 

   Included in net sales are product sales to other divisions of CMI. These 
sales totaled $3,584,000, $640,000 and $1,800,000 for 1995, 1996 and 1997, 
respectively. In addition, there is approximately $2,363,000, $2,937,000 and 
$776,000 of purchases from another division of CMI which is included in 
ending inventory and $2,139,000, $3,576,000 and $1,129,000 due to this 
division which is included in accounts payable at June 30, 1995, 1996 and 
1997, respectively. 

12. RESTRUCTURING 

   In June 1995, a decision was made to close the Division's Melbourne, 
Florida facility as well as to perform a review of personnel needs at the 
Division's operations. Pursuant to these decisions, approximately $2.4 
million of restructuring charges were recorded, including approximately 
$600,000 to reflect the facility at its net realizable value. There are no 
remaining cash outlays associated with the restructuring at June 30, 1997. 

   In December 1996 and January 1997, a comprehensive review of the 
Division's operations was performed, including a review of inventory levels, 
product development and migration plans and facility and personnel needs. It 
was determined to focus the Division on potentially higher margin products. 
This resulted in the write-down of certain inventories and the restructuring 
of the Division's operations. Inventory and other charges of $10,300,000, 
arising from this review, were included in cost of products sold and excess 
facilities and severance charges of $800,000 were included in restructuring. 
There are no remaining cash outlays associated with the restructuring at June 
30, 1997. 

13. SUBSEQUENT EVENTS 

   In November 1997, the Division recorded a $1 million charge to cost of 
sales relating to a contract with a customer in Sudan. The President of the 
United States imposed economic sanctions on Sudan which banned U.S. companies 
from doing business in Sudan, and as a result the Division could not continue 
to perform under the existing contract. Based upon this, the contract was 
terminated and the Division has been released from further performance 
requirements. 

   On December 19, 1997, L-3 Communications Corporation, an unrelated party, 
reached an agreement to purchase from CMI substantially all of the assets of 
the Division, and to assume certain of the liabilities of the Division, for 
approximately $27 million in cash. The final purchase price is subject to 
adjustment based on the net assets of the Division at the closing date of the 
transaction.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
                              DECEMBER 31, 1997 

(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES 

DESCRIPTION OF BUSINESS 

   ILEX Systems, Inc. (the "Company") provides services and products 
primarily in four areas: environmental consulting services to private and 
public sector customers; software consulting services to the federal 
government and its contractors; supervisory control and data acquisition 
products and services to the electrical utility industry; and secured 
communications products, principally to the federal government and its 
agencies. The majority of the Company's revenues are derived from its 
software consulting services. 

PRINCIPLES OF CONSOLIDATION 

   The accompanying consolidated financial statements include the financial 
statements of the Company and its wholly owned subsidiary. All significant 
intercompany balances and transactions have been eliminated in consolidation. 

REVENUE RECOGNITION 

   The Company's consulting services are generally performed on time-and 
materials-based contracts for the federal government and its contractors. 
Accordingly, revenues are recognized as services are performed. Equipment 
sales revenues are recognized upon shipment. Unbilled accounts receivable 
comprise charges for services and materials provided to customers that have 
not been invoiced. 

   The Company does not require collateral for its receivables. Reserves are 
maintained for potential credit losses. 

CASH EQUIVALENTS 

   Cash equivalents of $1,879,285 as of December 31, 1997, consist 
principally of money market investments. For purposes of the accompanying 
consolidated statement of cash flows, the Company considers all highly liquid 
debt instruments with remaining maturities of three months or less when 
acquired to be cash equivalents. 

FAIR VALUE OF FINANCIAL INSTRUMENTS 

   The carrying value of financial instruments in the Company's consolidated 
financial statements approximates fair value due to the short-term maturities 
of these instruments. 

INVENTORIES 

   Inventories are stated at the lower of cost (first-in, first-out basis) or 
market. 

PROPERTY, PLANT, AND EQUIPMENT 

   Property, plant, and equipment are stated at cost. Depreciation is 
calculated using the straight-line method over the estimated useful lives of 
the assets (generally five years). Leasehold improvements are amortized 
straight-line over the shorter of the lease term or the estimated useful life 
of the asset. 

GOODWILL 

   Goodwill, which represents the excess of purchase price over the fair 
value of net assets acquired, is amortized on a straight-line basis over the 
expected periods to be benefited of 10 to 15 years. The Company assesses the 
recoverability of goodwill by determining whether the amortization of the 
goodwill balance over its remaining life can be recovered through 
undiscounted future operating cash flows of the acquired operation. 

                              F-71

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>

                                 ========== 
</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>

</TABLE>

                              F-72           
<PAGE>
   (Continued) 
   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: 

<TABLE>

                 $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.

                        REPORT OF INDEPENDENT AUDITORS 

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

   We have audited the accompanying combined balance sheet of AlliedSignal 
Ocean Systems, a wholly owned operation of AlliedSignal, Inc. ("Ocean 
Systems"), as of December 31, 1997 and the related combined statements of 
operations, equity and cash flows for the year then ended. These financial 
statements are the responsibility of Ocean System's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audit. 

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

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the combined financial position of Ocean Systems as 
of December 31, 1997, and the combined results of their operations and cash 
flows for the year ended December 31, 1997, in conformity with generally 
accepted accounting principles.

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. 

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 

                              F-81

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. 

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

   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 
components:

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.

STATEMENT OF CASH FLOWS 

   The company participates in the AlliedSignal cash management system, under 
which all cash is received and payments are made by AlliedSignal. All 
transactions between the Company and AlliedSignal have been accounted for as 
settled in cash at the time such transactions were recorded by the Company. 

4. INVENTORIES AND CONTRACTS IN PROCESS

</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. 

5. PROPERTY, PLANT AND EQUIPMENT 

   Property, plant and equipment at December 31, 1997 are comprised of the 
following components:

6. INCOME TAXES 

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

<TABLE>
<CAPTION>
<S>                                    <C>
 Statutory federal income tax rate ....  (35.0)% 
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.
