                                 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 
Acquisitions was $146.4 million of cash, subject to certain post-closing 
adjustments, and in one case certain additional consideration based on 
post-closing performance. The Company has financed these acquisitions through 
the use of its existing cash balances as well as through borrowings under the 
$375.0 million Senior Credit Facilities (as defined). See "Description of 
Certain Indebtedness -- Senior Credit Facilities." These three businesses 
complement and extend L-3's product offerings. 

Ocean Systems 

   On March 30, 1998, L-3 Communications purchased the assets of the Ocean 
Systems business ("Ocean Systems") of AlliedSignal for $67.5 million in cash. 
In 1997, Ocean Systems had sales of $73.0 million. Ocean Systems is one of 
the world's leading products suppliers of acoustic undersea warfare systems, 
having designed, manufactured and supported a broad range of compact, 
lightweight, high performance acoustic systems for navies around the world 
for over 40 years. Ocean Systems is the leading products supplier of airborne 
dipping sonar systems in the world with substantial market share of the 
sector and systems in service with the U.S. and 20 foreign navies. Ocean 
Systems also produces several sea systems products including towed array 
sonar, integrated side-looking sonar, acoustic jammers, mine detection and 
torpedo defense systems and supplies commercial navigation and hydrographic 
survey systems worldwide. Ocean Systems is further supported by its ELAC 
Nautik GmbH ("ELAC") operations located in Kiel, Germany. ELAC manufactures a 
broad range of naval defense products including submarine, torpedo and 
navigation sonars as well as survey and navigation systems for the 

                                5           
<PAGE>
commercial nautical products industry. Ocean Systems expands L-3's leading 
products and capabilities into the undersea and anti-submarine warfare market 
place. 

ILEX Systems 

   On March 4, 1998, L-3 Communications purchased the assets of ILEX Systems 
("ILEX") for $51.9 million in cash, subject to adjustment based on closing 
net assets, plus additional consideration based on post-closing performance 
of ILEX, which could include the issuance of up to 540,000 shares of Common 
Stock over the next three years. In 1997, ILEX had sales of $63.5 million. 
ILEX is a leading supplier of communication software support services to 
military and related government intelligence markets. ILEX also provides 
environmental consulting, software and systems engineering services and 
complementary products to several commercial markets. ILEX complements L-3's 
Secure Communication Systems business area by adding software expertise in 
critical C(3)I programs and increasing the number of the Company's skilled 
workforce by adding approximately 500 software system engineers and 
scientists. 

Satellite Transmission Systems 

   On February 5, 1998, L-3 Communications purchased the assets of the 
Satellite Transmission Systems division ("STS") of California Microwave, Inc. 
for $27.0 million, subject to adjustment based on closing net assets. For the 
fiscal year ended June 30, 1997, STS had sales of $68.0 million. STS is a 
leading global satellite communications systems and services provider. Its 
customers include foreign post, telephone and telegraph administrations, 
domestic and international prime communications infrastructure contractors, 
telecommunications and satellite service providers, broadcasters and 
media-related companies, government agencies and large corporations. STS 
expands L-3's ability to apply its products and provides networking 
capability to L-3's wireless communications products business. STS also opens 
new opportunities in broader, international markets. 

   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 or 
results of operations of the Company. 

HISTORY 

   
   Holdings and L-3 Communications were formed in April 1997 by Mr. Frank C. 
Lanza, the former President and Chief Operating Officer of Loral Corporation 
("Loral"), Mr. Robert V. LaPenta, the former Senior Vice President and 
Controller of Loral (collectively, "Senior Management"), Lehman Brothers 
Capital Partners III, L.P. and its affiliates (the "Lehman Partnership") and 
Lockheed Martin to acquire (the "L-3 Acquisition") substantially all of the 
assets and certain liabilities of (i) nine business units previously 
purchased by Lockheed Martin as part of its acquisition of Loral in April 
1996 (the "Loral Acquired Businesses") and (ii) one business unit, 
Communication Systems -- East (formerly known as Communication Systems -- 
Camden), purchased by Lockheed Martin as part of its acquisition of the 
aerospace business of GE ("GE Aerospace") in April 1993 (collectively, the 
"Businesses"). L-3 Communications is a wholly-owned subsidiary of Holdings. 
Prior to the consummation of the Common Stock Offering, Messrs. Lanza and 
LaPenta and certain other members of management collectively own 17.8%; the 
Lehman Partnership owns 49.0%; and Lockheed Martin owns 33.2% of the 
outstanding capital stock of Holdings.

       accordance with generally accepted accounting principles as a measure 
       of profitability or liquidity. EBITDA is presented as additional

                                 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 Common Stock. 

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 $415.2 million of indebtedness 
outstanding, of which $36.9 million would have been Senior Debt (excluding 
letters of credit), and the Company's ratio of earnings to fixed charges 
would have been 1.0x 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 Indentures. 
    

   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 or obtain additional 
financing. The Company's ability to make scheduled principal payments of, 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 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, 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. See "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 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 

                               10           
<PAGE>
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 have 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 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 

                               11           
<PAGE>
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 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.

<PAGE>
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 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". 
    

                               13           
<PAGE>
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 38.6% of the outstanding voting stock of Holdings (or 37.4% 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 Common Stock. See 
"Ownership of Capital Stock". 
    

                               14           
<PAGE>
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. 

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 L-3 Communications' ability to finance 
its future operations or capital needs or engage in other business activities 
that may be in the interest of L-3 Communications. In addition, the Senior 
Credit Facilities also require L-3 Communications to maintain compliance with 
certain financial 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 and 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 
Certain Indebtedness".

ABSENCE OF PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE 

   Prior to the Common Stock Offering, there has been no public market for 
the Common Stock. There can be no assurance that an active trading market 
will develop for the Common Stock after the Common Stock Offering or, if 
developed, that such market will be sustained. The initial public offering 
price of the Common Stock will be based on negotiations between the Company 
and the Underwriters and may bear no relationship to the price at which the 
Common Stock will trade after the completion of the Common Stock Offering. 
See "Underwriting" for factors to be considered in determining the initial 
public offering price. In addition, quarterly operating results of the 
Company or other similar companies, changes in general conditions in the 
economy, the financial markets or the defense industry, natural disasters, 
changes in earnings estimates or recommendations by research analysts, or 
other developments affecting the Company or its competitors could cause the 
market price of the Common Stock to fluctuate substantially. In recent years, 
the stock market has experienced extreme price and volume fluctuations. This 
volatility has had a significant effect on the market prices of securities 
issued by many companies for reasons unrelated to the operating performance 
of these companies. 

   The Underwriters have advised the Company that they currently intend to 
make a market with respect to the Common Stock. However, the Underwriters are 
not obligated to do so, and any market-making with respect to the Common 
Stock 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 Common Stock, which may affect its ability to 
continue market-making activities. See "Underwriting". 

SHARES ELIGIBLE FOR FUTURE SALE 

   As of March 31, 1998, the Company had 20,457,142 shares of Common Stock 
outstanding (excluding shares of Common Stock offered hereby). After the 
Common Stock Offering, the holders of shares of Common Stock issued prior to 
the Common Stock Offering will be entitled to certain registration rights 
described below, at the expense of the Company. Such shares may also be sold 
under Rule 144 of the Securities Act, depending on the holding period of such 
securities and subject to restrictions in the case of shares held by persons 
deemed to be affiliates of the Company. No prediction can be made as to the 
effect, if any, that future sales of shares, or the availability of shares 
for future sale, will have on the market price of the Common Stock prevailing 
from time to time. Sales of substantial amounts of Common Stock (including 
shares issued upon the exercise of stock options), or the perception that 
such sales could occur, may adversely affect prevailing market prices for the 
Common Stock. 

   
   All executive officers and directors and the existing stockholders of 
Holdings who, after the Common Stock Offering, will hold in the aggregate 
20,457,142 shares of Common Stock, have agreed, pursuant to lock-up 
agreements, that they will not, without the prior written consent of Lehman 
Brothers Inc., offer, sell, contract to sell or otherwise dispose of any 
shares of Common Stock or securities exercisable or exchangeable for Common 
Stock or enter into any derivative transaction with similar effect as a sale 
of Common Stock for a period of 180 days after the date of this Prospectus. 
The restrictions described in this paragraph do not apply to (i) the sale of 
Common Stock to the Underwriters, (ii) the issuance by Holdings of shares of 
Common Stock upon the exercise of an option or a warrant or the conversion of 
a security outstanding on the date of this Prospectus or (iii) transactions 
by any person other than Holdings relating to shares of Common Stock or other 
securities acquired in open market transactions after the completion of the 
offering of the Common Stock. 
    

   The Company intends to file registration statements under the Securities 
Act to register all shares of Common Stock issuable pursuant to the 1997 
Stock Option Plan. Upon the completion of the 180-day period described above, 
236,250 shares of Common Stock issued under, or issued or issuable upon the 
exercise of awards issued under, such plans and after the effective date of 
such registration statements, generally will be eligible for sale in the 
public market. See "Management -- Executive Compensation". 

                               16           
<PAGE>
   Pursuant to the Stockholders Agreement, certain of the existing 
stockholders have the right, under certain circumstances 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 Agreement 
also provides all of the existing stockholders with certain piggyback 
registration rights. The Stockholders Agreement provides, among other things, 
that the Company will pay expenses in connection with (i) up to two demand 
registrations requested by Lockheed Martin, up to three demand registrations 
requested by the Lehman Partnership and the two demand registrations 
requested by the Senior Management and (ii) any registration in which the 
existing stockholders participate through piggyback registration rights 
granted under such agreement. 

POTENTIAL EFFECT OF CERTAIN ANTI-TAKEOVER PROVISIONS 

   Immediately prior to consummation of the Common Stock Offering, Holdings' 
Certificate of Incorporation and Bylaws will be amended to provide for a 
classified board of directors consisting of three classes and authorize the 
issuance preferred stock. Holdings Certificate of Incorporation and Bylaws 
contain certain other provisions that may discourage or prevent certain types 
of transactions involving an actual or potential change in control of 
Holdings, including transactions in which the stockholders might otherwise 
receive a premium for their shares over the current market prices, and may 
limit the ability of the stockholders to approve transactions that they may 
deem to be in their best interests. In addition, certain provisions of 
Delaware law applicable to the Company, including Section 203 of the Delaware 
General Corporation Law, could have the effect of delaying, deferring or 
preventing a change of control of Holdings. It is possible that the 
provisions in Holdings' Certificate of Incorporation and Bylaws, the 
concentration of ownership in the Lehman Partnership and Lockheed Martin and 
Section 203 of the Delaware General Corporation Law may have the effect of 
delaying, deferring or preventing a change of control of Holdings without 
further action by the stockholders, may discourage bids for Holdings' Common 
Stock at a premium over the market price of the Common Stock and may 
adversely affect the market price of the Common Stock and the voting and 
other rights of the holders of Common Stock. See "Description of Capital 
Stock". 

SUBSTANTIAL AND IMMEDIATE DILUTION 

   
   Purchasers of the Common Stock offered hereby will experience immediate 
and significant dilution in net tangible book value per share of 
approximately $24.86 per share of Common Stock (assuming no exercise of the 
over-allotment option by the Underwriters and an initial public offering 
price of $19.00 per share, which is the midpoint of the range of the 
estimated offering price per share set forth on the cover of this 
Prospectus). See "Dilution". 
    

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 Common Stock Offering are 
estimated to be approximately $96.5 million ($111.3 million if the 
over-allotment option is exercised in full), at an assumed initial public 
offering price of $19.00 per share, which is the midpoint of the range of the 
estimated offering price per share set forth on the cover of this Prospectus, 
after deducting underwriting discounts, commissions and estimated offering 
expenses. 

   The Company intends to use the net proceeds of the Common Stock Offering, 
together with the net proceeds of the Notes Offering, 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".

                                   DILUTION 

   
   As of March 31, 1998, the Company's net tangible deficit defined as total 
stockholders' equity plus common stock subject to repurchase agreement (which 
will convert to Common Stock after the Common Stock Offering), less 
intangibles, was $(12.14) per share. After giving effect to the Common Stock 
Offering (assuming that the Underwriters' over-allotment option is not 
exercised) at an assumed initial offering price of $19.00 per share, which is 
the midpoint of the range of the estimated offering price per share set forth 
on the cover of this Prospectus, and after deducting the Underwriters' 
discounts and commissions and estimated expenses of the Common Stock 
Offering, the pro forma net tangible deficit at March 31, 1998 was $(5.86) 
per share. This amount represents an immediate dilution in pro forma net 
tangible book value of $24.86 per share of Common Stock to new public 
investors. The following table illustrates this dilution:

                               DIVIDEND POLICY 

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

       UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION 

   
   The following unaudited pro forma financial information gives effect to 
the L-3 Acquisition, the 1998 Acquisitions and the Offerings (collectively, 
the "Transactions") as if they had occurred as of January 1, 1997. 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 for the 
1998 Acquisitions. Actual adjustments will be based on final appraisals and 
other analyses of fair values which are in process and adjustment of 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 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, 
   relating to the Predecessor Company 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 and 
   (d) a net increase to interest expense of $1.5 million, comprised of a 
   $0.2 million allocated interest expense reduction related to the Hycor 
   business and a net $1.7 million increase, reflecting pro forma interest 
   expense of $10.2 million based on actual borrowings of $400.0 million and 
   the effective cost of borrowing rate incurred by the Company to finance 
   the L-3 Acquisition less interest expense of approximately $8.5 million 
   included in the historical financial statements of the Predecessor 
   Company. A statutory (federal, state and foreign) tax rate of 39.0% was 
   assumed on these pro forma adjustments. 

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 STS and ILEX purchase prices are subject to adjustment based 
   upon the actual closing net assets 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. 

   
3. The pro forma statements of operations include the following historical 
   financial data for the 1998 Acquisitions: 
   The pro forma statement of operations for the three months ended March 31, 
   1998 includes the following historical data for the periods indicated for 
   the 1998 Acquisitions.

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.

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

7. Pro forma basic earnings per common share are computed based upon the 
   weighted-average number of shares of Common Stock outstanding, giving 
   effect to the Common Stock Offering. Pro forma diluted earnings per Common 
   Stock are computed based upon: (a) the weighted average number of shares 
   of Common Stock and potential Common Stock outstanding, to the extent the 
   potential common stock is not anti-dilutive, giving effect to the Common 
   Stock Offering; and (b) an assumed average market price of Common Stock 
   for the year ended December 31, 1997 and the three months ended March 31, 
   1998 and 1997 of $19.00 per share, based on the midpoint of the estimated 
   initial public offering price of the Common Stock, used for the assumed 
   purchase of common shares for treasury. For purposes of these earnings per 
   share computations, Class B Common Stock of Holdings subject to repurchase 
   agreement has been included in the weighted average number of shares of 
   Common Stock outstanding because the Class B Common Stock converts to 
   Class A Common Stock upon the completion of the Common Stock Offering.

       The amounts shown herein include only those amounts as reflected in the

 (5)   For periods prior to April 1, 1997, interest expense and income tax 
       (benefit) provision were allocated from Lockheed Martin. 
 (6)   EBITDA is defined as operating income plus depreciation expense and 
       amortization expense (excluding the amortization of deferred debt 
       issuance costs). 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. 
 (7)   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. 
 (8)   Earnings were insufficient to cover fixed charges by $0.5 million for 
       the three months ended March 31, 1997. 
 (9)   For purposes of this computation, cash interest expense consists of pro 
       forma interest expense excluding amortization of deferred debt issuance 
       costs. 
(10)   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. 
(11)   Net debt is defined as long-term debt plus current portion of long-term 
       debt less cash and cash equivalents.

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

   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. 

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 

                               32           
    
<PAGE>
   
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.

   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 $13.9 million, of which $5.8 
million is attributable to the Loral Acquired Businesses and $8.1 million to 
Communication Systems -- East. 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 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 39%. 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

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). 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 $63.8 million in the 1997 
period from $51.5 million in the 1996 period. Operating income is not 
directly comparable between the periods as a result of the effects of 
valuation of assets and liabilities in accordance with Accounting Principles 
Opinion No. 16. 

   The sales increase in the 1997 period was primarily attributable to sales 
of the Loral Acquired Businesses which increased by $18.1 million to $531.4 
million in the 1997 period as compared to 

                               34           
<PAGE>
$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 23.9% to $63.8 million in the 1997 period 
from $51.5 million in the 1996 period. Operating income as a percentage of 
sales increased to 9.0% 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 reflected fourth quarter cost of sales of $3.3 
million related to on-going certification efforts for the Company's EDS 
contract. Excluding 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.

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

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

   The increase in 1996 operating income was largely attributable to the 
Loral Acquired Businesses, which contributed $36.9 million of the increase. 
Communication Systems -East operating income in 1996 increased $2.2 million 
primarily due to improved operating performance on the Shipboard Telephone 
Communications ("STC-2") program partially offset by increased costs on the 
Space Station contract. 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. 

                               35           
<PAGE>
   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 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 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, 

                               36           
<PAGE>
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. 

   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.

   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; 
proceeds of $3.0 million from the exercise of stock options 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 nil, 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. 
    

                               39           
<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 
    

                               40           
<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.

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

   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.

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 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 

                               46           
<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 
    

                               47           
<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 supplier 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. 
    

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 STS, ILEX and Ocean Systems. The combined purchase price 
for the 1998 Acquisitions was $146.4 million of cash, subject to certain 
post-closing adjustments, and in one case certain additional consideration 
based on post-closing performance. The Company has financed these 
acquisitions through the use of its existing cash balances as well as through 
borrowings under the $375.0 million Senior Credit Facilities. These three 
businesses complement and extend L-3's product offerings. 

 Ocean Systems 

   On March 30, 1998, L-3 Communications purchased the assets of Ocean 
Systems for $67.5 million in cash. In 1997, Ocean Systems had sales of $73.0 
million. Ocean Systems is one of the world's leading products suppliers of 
acoustic undersea warfare systems, having designed, manufactured and 
supported a broad range of compact, lightweight, high performance acoustic 
systems for navies around the world for over 40 years. Ocean Systems is the

and 20 foreign navies. Ocean Systems also produces several sea systems 
products including towed array sonar, integrated side-looking sonar, acoustic 
jammers, mine detection and torpedo defense systems and supplies commercial 
navigation and hydrographic survey systems worldwide. Ocean Systems is 
further supported by ELAC located in Kiel, Germany. ELAC manufactures a broad 
range of naval defense products including submarine, torpedo and navigation 
sonars as well as survey and navigation systems for the commercial nautical 
products industry. Ocean Systems expands L-3's leading products and 
capabilities into the undersea and anti-submarine warfare market place. 

 ILEX Systems 

   On March 4, 1998, L-3 Communications purchased the assets of ILEX for 
$51.9 million in cash, subject to adjustment based on closing net assets, 
plus additional consideration based on post-closing performance of ILEX which 
could include the issuance of up to 540,000 shares of Common Stock over the 
next three years. In 1997, ILEX had sales of $63.5 million. ILEX is a leading 
supplier of communication software support services to military and related 
government intelligence markets. ILEX also provides environmental consulting, 
software and systems engineering services and complementary products to 
several commercial markets. ILEX complements L-3's Secure Communication 
Systems business area by adding software expertise in critical C(3)I programs 
and increasing the number of the Company's skilled workforce by adding 
approximately 500 software system engineers and scientists.

provides networking capability to L-3's wireless communications products 
business. STS also opens new opportunities in broader, international markets. 

   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 or 
results of operations of the Company. 

HISTORY 

   Holdings and L-3 Communications were formed in April 1997 by Mr. Frank C. 
Lanza, the former President and Chief Operating Officer of Loral, Mr. Robert 
V. LaPenta, the former Senior Vice President and Controller of Loral 
(collectively, "Senior Management"), Lehman Brothers Capital Partners III, 
L.P. and its affiliates (the "Lehman Partnership") and Lockheed Martin to 
acquire (the "L-3 Acquisition") substantially all of the assets and certain 
liabilities of (i) nine business units previously purchased by Lockheed

                               49           
<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

traffic control. The Company also offers on-board, high data rate 
communications systems which provide a data link for carrier battle groups 
which are interoperable with the U.S. Air Force's surveillance/ 
reconnaissance terminal platforms. The Company provides the US Army's Command 
and Control Vehicle ("C(2)V") Mission Module Systems ("MMS"). MMS provides 
the "communications on the move" capability needed for the digital 
battlefield by packaging advanced communications into a modified Bradley 
Fighting Vehicle. The Company is a proven supplier of superior technological 
expertise to the DoD, including its contractors and related government 
intelligence agencies. 

O INFORMATION SECURITY SYSTEMS 

   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. 

SPECIALIZED COMMUNICATION PRODUCTS 

MICROWAVE COMPONENTS 

   L-3 is the preeminent worldwide supplier of commercial off-the-shelf, high 
performance radio frequency ("RF") microwave components, assemblies and 
instruments supplying the wireless communications, industrial and military 
markets. The Company is also a leading provider of state-of-the-art 
space-qualified commercial satellite and strategic military RF products. L-3 
sells many of these components under the well-recognized Narda brand name and 
through the world's most comprehensive catalog of standard, stocked hardware. 
L-3 also sells its products through a direct sales force and an extensive 
network of premier market representatives. Specific catalog offerings include 
wireless products, electro-mechanical switches, power dividers and hybrids, 
couplers/detectors, attenuators, terminations and phase shifters, isolators 
and circulators, adapters, control products, sources, mixers, waveguide 
components, RF safety products, power meters/monitors and custom passive 
products. The Company operates from two sites, Hauppauge, New York ("Narda 
East"), and Sacramento, California ("Narda West"). 

   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. 

                               51           
<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.

   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 

                               52           
<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 
aircraft and rotary joints for the AWAC's and E-2C's antenna. Randtron has 
delivered over 2,000 aircraft sets of antennas and has a current backlog 
through 1999. 

O DISPLAY SYSTEMS 

   L-3 specializes in the design, development and manufacture of ruggedized 
display system solutions for military and high-end commercial applications. 
L-3's current product lines include cathode ray tubes ("CRTs"), the Actiview 
family of active matrix liquid crystal displays ("AMLCD"), and a family of 
high performance Display Processing systems. L-3 manufactures flat-panel 
displays that are used on platforms such as E-2C, F-117, and the LCAC 
(Landing Craft Air Cushion) vehicle. Recent new contracts for flat-panel 
displays include the SH-60J helicopter and the C-130 Senior Scout. L-3 also 
manufactures CRT displays for the E-2C Hawkeye, V-22 Osprey, and F-14 Tomcat 
and electronics used in aircraft anti-lock braking systems. 

O OCEAN SYSTEMS 

   The Company is one of the world's leading suppliers of acoustic undersea 
warfare systems, having designed, manufactured and supported a broad range of 
compact, lightweight, high performance acoustic systems for navies around the 
world for over forty years. This experience spans a wide range of platforms, 
including helicopters, submarines and surface ships, that employ the 
Company's sonar systems and countermeasures. 

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 

                               53           
<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. 

EMERGING COMMERCIAL PRODUCTS 

O MEDICAL ARCHIVING AND SIMULATION SYSTEMS 

   
   The Company markets jointly with GE Medical Systems GEMnet(Trademark), a

technicians to become more productive. EchoNet(Trademark) is a trademark of 
Heartlab, Inc. GEMnet(Trademark) is a trademark of GE. 
    

   The Company has approximately a one-third equity ownership interest in 
Medical Education Technologies, Inc. ("METI"). METI is a medical technology 
company engaged in the development, manufacture and sale of Human Patient 
Simulators ("HPS"). The HPS is a computerized system with a life-like 
mannequin that reacts to medical treatments and interventions similar to a 
human being. Originally oriented to the anesthesiology training and education 
domain, METI has expanded into cardiology, critical care, trauma care, allied 
health care, military medicine and continuing medical education. METI's 
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 

                               54           
<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 

                               55           
<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.

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. 

                               57           
<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 the 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 

   Pursuant to the L-3 Acquisition Agreement, Holdings and L-3 Communications 
assumed certain liabilities relating to defined benefit pension plans for 
present and former employees and retirees of certain businesses which were 
transferred from Lockheed Martin to Holdings and L-3 Communications. Prior to 
the consummation of the L-3 Acquisition, Lockheed Martin received a letter 
from the PBGC which requested information regarding the transfer of such 
pension plans and indicated that the PBGC believed certain of such pension 
plans were underfunded using the PBGC's actuarial assumptions (which 
assumptions result in a larger liability for accrued benefits than the 
assumptions used for financial reporting under FASB 87.) The PBGC 
underfunding is related to the Subject Plans. As of 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, 

                               58           
<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.

   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 a material disruption to 
operations of ELAC or Ocean Systems will not occur.

                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 for 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 

                               60           
<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%.

until their earlier resignation or removal, if any. To the extent there is an

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 for 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 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 description 
       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 1997 fiscal year, Messrs. Robert Millard, Steven Berger 
and John Montague served as members of the Compensation Committee. None of 
these individuals has served at any time as an officer or employee of 

                               67           
<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 affiiliated with the Lehman Partnership which, 
assuming the consummation of the Common Stock Offering and full exercise of 
the over-allotment option, holds 37.4% 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.

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.

                          OWNERSHIP OF CAPITAL STOCK 

   Following the consummation of the Common Stock Offering, the existing 
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 
and as a group.

                     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.

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

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 on a parity or 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,

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

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

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.

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 CAPITAL STOCK 

GENERAL 

   
   As of the date of this Prospectus, the Amended and Restated Certificate of 
Incorporation of Holdings authorizes 25,000,000 shares of Class A Common 
Stock, par value $0.01 per share, 3,000,000 shares of Class B Common Stock, 
par value $0.01 per share, and 3,000,000 shares of Class C Common Stock, par 
value $0.01 per share. Immediately prior to the consummation of the Common 
Stock Offering, Holdings intends to amend its Certificate of Incorporation to 
convert the different classes of common stock into one class, the Common 
Stock, with each outstanding share of Class A and Class B Common Stock being 
converted into one share of Common Stock, and to increase the authorized 
shares to 100,000,000 shares of Common Stock. Unless the context otherwise 
requires, this Prospectus assumes the completion of such conversion of Class 
A and Class B Common Stock into the Common Stock. As of March 31, 1998, the 
outstanding capital stock of Holdings consisted of 20,457,142 shares of 
Common Stock held by 26 stockholders of record. The following summaries of 
certain provisions of the Common Stock do not purport to be complete and are 
subject to, and qualified in their entirety by, the provisions of the Amended 
and Restated Certificate of Incorporation and Bylaws of Holdings, which are 
included as exhibits to the Registration Statement of which this Prospectus 
forms a part, and by applicable law. 
    

COMMON STOCK 

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

PREFERRED STOCK 

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

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW 

   The Company is a Delaware corporation subject to Section 203 of the DGCL 
("Section 203"). Section 203 provides in general that a stockholder acquiring 
more than 15% of the outstanding voting stock of a corporation subject to 
Section 203 (an "Interested Stockholder") but less than 85% of such stock may 
not engage in certain Business Combinations (as defined in Section 203) with 
the corporation for a period of three years subsequent to the date on which 
the stockholder became an Interested 

                               75           
<PAGE>
Stockholder unless (i) prior to such date the corporation's board of 
directors approved either the Business Combination or the transaction in 
which the stockholder became an Interested Stockholder or (ii) the Business 
Combination is approved by the corporation's board of directors and 
authorized by a vote of at least 66 2/3% of the outstanding voting stock of 
the corporation not owned by the Interested Stockholder. A "Business 
Combination" includes mergers, asset sales and other transactions resulting 
in financial benefit to a stockholder. Section 203 could prohibit or delay 
mergers or other takeover or change of control attempts with respect to the 
Company and, accordingly, may discourage attempts that might result in a 
premium over the market price for the shares held by stockholders. 

TRANSFER AGENT AND REGISTRAR 

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

                       SHARES ELIGIBLE FOR FUTURE SALE 

GENERAL 

   Prior to completion of the Common Stock Offering, there has been no public 
market for the Common Stock. Sales of substantial amounts of Common Stock in 
the public market, or the perception that such sales may occur, could 
adversely affect the market price of the Common Stock. 

   
   Upon the consummation of the Common Stock Offering, Holdings will have 
25,957,142 shares of Common Stock issued and outstanding. All of the 
5,500,000 shares of Common Stock to be sold in the Common Stock Offering (and 
any shares sold upon exercise of the U.S. Underwriters' over-allotment 
option) will be freely tradable without restrictions or further registration 
under the Securities Act, except for any shares purchased by an "affiliate" 
of Holdings (as that term is defined in Rule 144 under the Securities Act 
("Rule 144")), which will be subject to the resale limitations of Rule 144. 
The remaining shares of Common Stock outstanding are "restricted securities" 
as that term is defined in Rule 144 and are also subject to certain 
restrictions on disposition. Restricted securities may be sold in the public 
market only if registered or if they qualify for an exemption from 
registration under Rule 144 or Rule 701 under the Securities Act. Sales of 
restricted securities in the public market, or the availability of such 
shares for sale, could have an adverse effect on the price of the Common 
Stock. See "Risk Factors -- Absence of Public Market; Possible Volatility of 
Stock Price", "Risk Factors -- Substantial and Immediate Dilution", "Risk 
Factors -- Shares Eligible for Future Sale" and "Dilution". 
    

RULE 144 

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

   
   All executive officers and directors and the existing stockholders of 
Holdings who, after the Common Stock Offering, will hold in the aggregate 
20,457,142 shares of Common Stock have agreed, pursuant to lock-up 
agreements, that they will not, without the prior written consent of Lehman 
Brothers Inc., offer, sell, contract to sell or otherwise dispose of any 
shares of Common Stock or securities exercisable or exchangeable for Common 
Stock or enter into any derivative transaction with similar effect as a sale 
of Common Stock for a period of 180 days after the date of this Prospectus. 
The restrictions described in this paragraph do not apply to (i) the sale of 
Common Stock to the Underwriters, (ii) the issuance by Holdings 
    

                               76           
<PAGE>
of shares of Common Stock upon the exercise of an option or a warrant or the 
conversion of a security outstanding on the date of this Prospectus or (iii) 
transactions by any person other than Holdings relating to shares of Common 
Stock or other securities acquired in open market transactions after the 
completion of the offering of the Common Stock. 

   The Company intends to file registration statements under the Securities 
Act to register all shares of Common Stock issuable pursuant to the 1997 
Stock Option Plan. Subject to the completion of the 180-day period described 
above, shares of Common Stock issued under, or issued upon the exercise of 
awards issued under such plans and after the effective date of such 
registration statements, generally will be eligible for sale in the public 
market. See "Management -- Executive Compensation". 

REGISTRATION RIGHTS 

   Pursuant to the Stockholders Agreement, certain of the existing 
stockholders have the right, under certain circumstances and subject to 
certain conditions, to require the Company to register under the Securities

                   UNITED STATES FEDERAL TAX CONSIDERATIONS 

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

DIVIDENDS 

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

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

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

GAIN ON DISPOSITION OF COMMON STOCK 

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

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

                               78           
<PAGE>
the sale, which may be offset by United States source capital losses (even 
though the individual is not considered a resident of the United States). If 
a Non-U.S. Holder that is a foreign corporation falls under clause (i) above, 
it will be subject to tax on its gain under regular graduated United States 
federal income tax rates and, in addition, may be subject to the branch 
profits tax equal to 30% of its effectively connected earnings and profits 
within the meaning of the Code for the taxable year, as adjusted for certain 
items, unless it qualifies for a lower rate under an applicable income tax 
treaty. The Company is not and does not anticipate becoming a "U.S. real 
property holding corporation" for United States federal income tax purposes. 

FEDERAL ESTATE TAX 

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

INFORMATION REPORTING AND BACKUP WITHHOLDING 

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

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

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

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

   The U.S. Underwriting Agreement and the International Underwriting 
Agreement (collectively, the "Underwriting Agreements") provide that the 
obligations of the U.S. Underwriters and the International Managers to 
purchase shares of Common Stock are subject to certain conditions, and that 
if any of the foregoing shares of Common Stock are purchased by the U.S. 
Underwriters pursuant to the U.S. Underwriting Agreement or by the 
International Managers pursuant to the International Underwriting Agreement, 
then all the shares of Common Stock agreed to be purchased by the U.S. 
Underwriters and the International Managers, as the case may be, pursuant to 
their respective Underwriting Agreements, 

                               80           
<PAGE>
must be so purchased. The offering price and underwriting discounts and 
commissions per share for the U.S. Offering and the International Offering 
are identical. The closing of the U.S. Offering is a condition to the closing 
of the International Offering and the closing of the International Offering 
is a condition to the closing of the U.S. Offering. 

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

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

   
   Holdings has granted to the U.S. Underwriters options to purchase up to an 
aggregate of 825,000 additional shares of Common Stock, exercisable solely to 
cover over-allotments, at the public offering price less the underwriting 
discounts and commissions shown on the cover page of this Prospectus. Such 
options may be exercised at any time until 30 days after the date of the U.S. 
Underwriting Agreement. To the extent that the over-allotment option is 
exercised, each U.S. Underwriter or International Manager, as the case may 
be, will be committed, subject to certain conditions, to purchase a number of 
additional shares of Common Stock proportionate to such U.S. Underwriter's or 
International Manager's initial commitment as indicated in the preceding 
tables. 
    

   Prior to the Common Stock Offering, there has been no public market for 
the shares of Common Stock. The initial public offering price was negotiated 
between Holdings and the Representatives. Among the factors considered in 
determining the initial public offering price of the shares of Common Stock, 
in addition to prevailing market conditions, were the Company's historical 
performance and capital structure, estimates of business potential and 
earning prospects of the Company, an overall assessment of the Company, an 
assessment of the Company's management and the consideration of the above 
factors in relation to market valuation of companies in related businesses. 

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

   The foregoing limitations do not apply to stabilization transactions or to 
certain other transactions specified in the Underwriting Agreements and the 
Agreement Between U.S. Underwriters and International Managers, including (i) 
certain purchases and sales between U.S. Underwriters and the International 
Managers, (ii) certain offers, sales, resales, deliveries or distributions to 
or through investment advisors or other persons exercising investment 
discretion, (iii) purchases, offers or sales by a U.S. Underwriter who is 
also acting as an International Manager or by an International Manager who is 
also acting as a U.S. Underwriter and (iv) other transactions specifically 
approved by the U.S. Representatives and the Lead Managers. As used herein, 
the term "U.S. Person" means any resident or national of the United States or 
Canada and its provinces, any corporation, partnership or other entity 
created or organized in or under the laws of the United States or Canada and 
its provinces, or any estate 

                               81           
<PAGE>
or trust the income of which is subject to United States or Canadian federal 
income taxation regardless of the source, and the term "United States" means 
the United States of America (including the District of Columbia) and its 
territories, its possessions and other areas subject to its jurisdiction. 

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

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

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

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

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

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

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

   The Common Stock has been approved for listing, subject to notice of 
issuance, on the NYSE under the symbol    . 

   Holdings, all executive officer and director of Holdings and existing 
stockholders of Holdings have agreed that they will not, subject to certain 
limited exceptions, for a period of 180 days from the date of this 
Prospectus, directly or indirectly, offer, sell or otherwise dispose of any 
shares of Common Stock or any securities convertible into or exchangeable or 
exercisable for any such shares of Common Stock or enter into any derivative 
transaction with similar effect as a sale of Common Stock, without the prior 
written consent of Lehman Brothers Inc. The restrictions described in this 
paragraph do not apply to (i) the sale of Common Stock to the Underwriters, 
(ii) the issuance by Holdings of shares of Common Stock upon the exercise of 
an option or a warrant or the conversion of a security outstanding on the 
date of this Prospectus or (iii) transactions by any person other than 
Holdings relating to shares of Common Stock or other securities acquired in 
open market transactions after the completion of the Common Stock Offering. 

   At the request of Holdings, the Underwriters have reserved for sale, at 
the initial offering price, up to 500,000 shares of Common Stock offered 
hereby for directors, officers, employees, business associates, and related 
persons of the Company. The number of shares of Common Stock available for 
sale to the general public will be reduced to the extent such persons 
purchase such reserved shares. Any reserved shares which are not so purchased 
will be offered by the Underwriters to the general public on the same basis 
as the other shares offered hereby. 
    

   Any offer of the shares of Common Stock in Canada will be made only 
pursuant to an exemption from the prospectus filing requirement and an 
exemption from the dealer registration requirement (where such an exemption 
is not available, offers shall be made only by a registered dealer) in the 
relevant Canadian jurisdiction where such offer is made. 

   Purchasers of the shares of Common Stock offered hereby may be required to 
pay stamp taxes and other charges in accordance with the laws and practices 
of the country of purchase, in addition to the offering price set forth on 
the cover hereof. 

   The U.S. Underwriters and the International Managers have informed 
Holdings that they do not intend to sell to, and therefore will not confirm 
the sales of shares of Common Stock offered hereby to any accounts over which 
they exercise discretionary authority without prior written approval of the 
customer. 

   
   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 Notes Offering, and Lehman Brothers Commercial 
Paper Inc., an affiliate of Lehman Brothers Inc., is the Arranger and 
Syndication Agent under the Senior Credit Facilities, a substantial portion 
of which will be refinanced with net proceeds of the Offerings. 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. After the completion of the Common Stock Offering and 
assuming that the Underwriters' over-allotment option is exercised, the 
Lehman Partnership will beneficially own 37.4% of the outstanding capital 
stock of Holdings and will be able to significantly influence the business 
and the affairs of the Company with respect to matters requiring stockholder 
approval. See "Management--Directors and Executive Officer" 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 Common Stock 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 equity securities, the public offering price per share can be no 
higher 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 public offering price for the Common Stock in compliance with the 
requirements of Rule 2720. In connection with the Common

1. BASIS OF PRESENTATION 

   The accompanying condensed consolidated (combined) financial statements 
include the assets, liabilities and results of operations of L-3 
Communications Holdings, Inc., the successor company ("Holdings" and, 
together with its subsidiaries, "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 Communications Corporation ("L-3 Communications") was formed on April 
8, 1997, and is a wholly-owned subsidiary of Holdings. 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. 

   The Company has no assets or liabilities and conducts no operations other 
than through its investment in its wholly-owned subsidiary, L-3 
Communications Corporation. 

   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 
              (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) 

   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 ("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.

   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 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 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. 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 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. 

   In February 1998, Holdings filed a registration statement with the 
Securities and Exchange Commission ("SEC") for the sale of 5.5 million shares 
of Common Stock (the "Common Stock Offering"), and concurrently with the 
Common Stock Offering, L-3 Communications filed a registration statement with 
the SEC for the sale of $150,000 aggregate principal amount of Senior 
Subordinated Notes due 2008 (the "Notes Offering"). 

6. STOCK OPTIONS 

   On March 2, 1998, Messrs. Lanza and LaPenta each exercised options to 
purchase 228,571 shares of Class A Common Stock. The options were granted on 
April 30, 1997 at an exercise price of $6.47. Accordingly, the Company 
received aggregate proceeds of $2,958 for such exercise and issued 457,124 
shares of Class A Common Stock.

   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 Holdings, Inc. 

   We have audited the accompanying (i) consolidated balance sheet of L-3 
Communications Holdings, Inc. and subsidiaries (the "Company") as of December 
31, 1997, and the related consolidated statements of operations, changes in 
shareholders' equity, and cash flows for the nine months then ended, (ii) the 
combined statements of operations and cash flows of the Predecessor Company, 
as defined in Note 1 to the Company's financial statements, for the three 
months ended March 31, 1997 and (iii) combined balance sheet of the 
Predecessor Company as of December 31, 1996 and the related combined 
statements of operations, changes in invested equity and cash flows for the 
year then ended. These financial statements are the responsibility of the 
Company's management. Our responsibility is to express an opinion on these 
financial statements based on our audits. We did not audit the 1996 financial 
statements of the Lockheed Martin Communications Systems Division, which 
statements reflect total assets and sales constituting 35 percent and 30 
percent of the related combined totals. Those statements were audited by 
other auditors whose report has been furnished to us, and our opinion, 
insofar as it relates to the amounts included for the Lockheed Martin 
Communications Systems Division for 1996, is based solely on the report of 
the other auditors. 

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

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

Board of Directors 
Lockheed Martin Corporation: 

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

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

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

               (In thousands, except share and per share data) 
    

1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS 

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

   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 

   L-3 was formed by Mr. Frank C. Lanza, the former President and Chief 
Operating Officer of Loral, Mr. Robert V. LaPenta, the former Senior Vice 
President and Controller of Loral (collectively, the "Equity Executives"), 
Lehman Brothers Capital Partners III, L.P. and its affiliates (the "Lehman 
Partnership") and Lockheed Martin to acquire the Businesses. The Equity 
Executives, the Lehman Partnership and Lockheed Martin own 14.9%, 50.1% and 
34.0% of the Company, respectively. 

   The Company has no assets or liabilities and conducts no operations other 
than through its investment in its wholly-owned subsidiary, L-3 Communication 
Corporation. 

   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. 

                              F-19           
<PAGE>
                      L-3 COMMUNICATIONS HOLDINGS, INC. 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
               (In thousands, except share and per share data) 

    The Company and Lockheed Martin finalized the purchase price adjustment 
pursuant to an amendment to the L-3 Acquisition Agreement dated November 5, 
1997, which also included the assumption by the Company of Lockheed Martin's 
rights and obligations under a contract for the U.S. Army's Command and 
Control Vehicle ("C(2)V") Mission Module Systems ("MMS"), for the production 
of mission communication systems for track vehicles, for which the Company 
received a cash payment of $12,176. 

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

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

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

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

   Had the L-3 Acquisition occurred on January 1, 1996, the unaudited pro 
forma sales, net income, basic earnings per common share and diluted earnings 
per common share for the years ended December 31, 1997 and 1996 would have 
been $703,600 and $16,300, $0.82 and $0.81, and $663,200 and $9,700, $0.49 
and $0.48, 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, net income and earnings per common share data 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. 

                              F-20           
<PAGE>
                      L-3 COMMUNICATIONS HOLDINGS, INC. 
      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
               (In thousands, except share and per share data) 

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

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

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

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

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

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

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

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

   Intangibles of the Predecessor Company include costs allocated to the 
Businesses relating to the Request for Funding Authorization ("RFA"), 
consisting of over 20 restructuring projects to reduce operating costs, 
initiated by General Electric ("GE") Aerospace in 1990 and to the REC Advance 
Agreement ("RAA"), a restructuring plan initiated after Lockheed Martin's 
acquisition of GE Aerospace. The RAA was initiated to close two regional 
electronic manufacturing centers. Restructure costs are reimbursable from the 
U.S. Government if savings can be demonstrated to exceed costs. The total 
cost of restructuring under the RFA and the RAA represented approximately 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 

                              F-21

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
               (In thousands, except share and per share data) 

Systems Division, on a basis that includes manufacturing labor, overhead, and 
direct material less non-hardware subcontracts. At December 31, 1997 and 
1996, approximately $2,313 and $4,400, respectively, of unamortized RFA and 
RAA costs are deferred on the Company's and the Predecessor Company's 
consolidated (combined) balance sheets in other current assets and other 
assets. 

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

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

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

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

   STOCK OPTIONS: In accordance with Accounting Principles Board Opinion No. 
25, "Accounting for Stock Issued to Employees" ("APB 25") and related 
interpretations, compensation expense for stock options is recognized in 
income based on the excess, if any, of 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 the Company's 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

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
               (In thousands, except share and per share data) 

most significant of these estimates and assumptions relate to contract 
estimates of sales and costs, allocations from Lockheed Martin, 
recoverability of recorded amounts of fixed assets and cost in excess of net 
assets acquired, litigation and environmental obligations. Actual results 
could differ from these estimates. 

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

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

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

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

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

4. PREDECESSOR COMPANY ACQUISITION 

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

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

6. NET ASSETS HELD FOR SALE 

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

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

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

</TABLE>


   In connection with the L-3 Acquisition, the Company entered into a credit 
facility (the "Senior Credit Facilities") with a syndicate of banks and 
financial institutions for $275,000 consisting of $175,000 of term loans (the 
"Term Loan Facilities") and a $100,000 revolving credit facility (the 
"Revolving Credit Facility"). The Senior Credit Facilities bear interest, at 
the option of the Company, at rates related to (i) the higher of federal 
funds rate plus 0.50% per annum or the reference rate published by Bank of 
America NT&SA or (ii) LIBOR. At December 31, 1997, such interest rates, based 
on various maturities, ranged from 7.625% to 8.625%. Interest payments vary 
in accordance with the type of borrowing and are made at a minimum every 
three months. The Revolving Credit Facility expires in 2003 and is available 
for ongoing working capital and letter of credit needs. The Term Loans mature 
in installments until the final maturity date in 2006. Approximately $93,428 
of the Revolving Credit Facility is available at December 31, 1997 reflecting 
letters of credit of $6,572 drawn against the Revolving Credit Facility of 
$100,000. In February 1998, the Senior Credit Facilities were amended to, 
among other things, increase

the Revolving Credit Facility to $200,000, waive certain excess cash flow 
prepayments, as defined, otherwise required, and permit the incurrence of up 
to an additional $150,000 of subordinated debt. The Company pays a commitment 
fee of 0.375% per annum on the unused portion of the Revolving Credit 
Facility. 

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

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

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

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

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

9. PREDECESSOR COMPANY'S INTEREST EXPENSE 

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

10. FINANCIAL INSTRUMENTS 

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

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

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

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

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

11. COMMON STOCK 

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

                              F-27

to shareholders agreements, the holders of Classes B and C Common Stock have 
the right to designate themselves as members of the Board of Directors as 
long as they are employees of the Company or any of its subsidiaries. Each 
share of Class B Common Stock will convert, at the option of the Company, 
into a share of Class A common stock immediately prior to an initial public 
offering of equity securities of the Company or upon the occurrence of 
certain other events but not later than April, 2006, and will convert into 
Class C common stock upon certain other events. Holders of Class B Common 
Stock are entitled to share with the holders of Class A Common Stock in 
dividends and liquidating distributions. 

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

because the Businesses were wholly-owned business units of Lockheed Martin 
prior to the L-3 Acquisition. 

13. INCOME TAXES 

THE COMPANY 

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

</TABLE>

   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.

14. STOCK OPTIONS 

THE COMPANY 

   The Company 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, the Company 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 the 
Company. 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, the Company 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 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 the Company 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 the Company's 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.

</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.

   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, the Company has agreed to 
assume certain on-site and off-site environmental liabilities related to 
events or activities occurring prior to the consummation of the L-3 
Acquisition. Lockheed Martin has agreed to retain all environmental 
liabilities for all facilities not used by the Businesses as of April 1997 
and to indemnify fully 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 March 31, 1997 relating 
to certain Company-assumed environmental liabilities and, for the seven years 
thereafter, to pay 40% of certain reasonable operation and maintenance costs 
relating to any environmental

remediation projects undertaken in the first eight years. The Company 
believes that its total liability for known or reasonably probable 
environmental claims, even without consideration of the Lockheed Martin 
indemnification, would not either individually or collectively have a 
material adverse effect upon 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. 

16. PENSIONS AND OTHER EMPLOYEE BENEFITS 

THE COMPANY 

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

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

   The following assumptions were used in accounting for pension plans for 
the Company: 

<TABLE>

Rate of return on plan assets  ...       9.00%            9.00% 
</TABLE>

   In connection with the Company's assumption of certain plan obligations 
pursuant to the L-3 Acquisition, Lockheed Martin has provided the PBGC with 
commitments to assume sponsorship or other forms of financial support under 
certain circumstances. In this connection, the Company has provided certain 
assurances to Lockheed Martin including, but not limited to, (i) continuing 
to fund the pension plans consistent with prior practices and to the extent 
deductible for tax purposes and, where appropriate, recoverable under 
Government contracts, (ii) agreeing to not increase benefits under the 
pension plans without the consent of Lockheed Martin, (iii) restricting the 
Company from a sale of any businesses employing individuals covered by the 
pension plans if such sale would not result in reduction or elimination of 
the Lockheed Martin Commitment with regard to the specific plan and (iv) if 
the pension plans were returned to Lockheed Martin, granting Lockheed Martin 
the right to seek recovery from the Company of those amounts actually paid, 
if any, by Lockheed Martin with regard to the pension plans after their 
return. 

   POST-RETIREMENT HEALTH CARE AND LIFE INSURANCE: In addition to providing 
pension benefits, the Company provides certain health care and life insurance 
benefits for retired employees and dependents at certain locations. 
Participants are eligible for these benefits when they retire from active 
service and meet the eligibility requirements for the Company's pension 
plans. These benefits are funded primarily on a pay-as-you-go basis with the 
retiree generally paying a portion of the cost through contributions, 
deductibles and coinsurance provisions. 

   Post-retirement health care and life insurance costs for the nine months 
ended December 31, 1997 include the following components:

</TABLE>

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

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

THE PREDECESSOR COMPANY 

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

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

matched contributions of participating employees up to a designated level. 
Under these plans the matching contributions for the three months ended March 
31, 1997 and for the years ended December 31, 1996 and 1995 were $1,241, 
$3,940 and $1,478, respectively.

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

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

   In December 1997, pursuant to an agreement among the shareholders of the 
Company effective April 30, 1997, Lockheed Martin and Messrs. Lanza and 
LaPenta sold 236,000 shares to the Company at a price of $6.47 per share 
conditioned upon the Company's immediate resale of such shares to certain 
management investors (other than Messrs. Lanza and LaPenta) at the same $6.47 
price per share. In connection with the resale, the Company made recourse 
loans to certain of those management investors aggregating approximately $679 
which are due in two installments in March 1998 and 1999. These amounts have 
been included in other assets in the Company's accompanying balance sheet.

      NOTES TO CONSOLIDATED (COMBINED) FINANCIAL STATEMENTS--(continued) 
               (In thousands, except share and per share data) 

   
    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. 

20. SUBSEQUENT EVENTS 

   In February 1998, the Company purchased substantially all the assets and 
liabilities of the Satellite Transmission Systems division of California 
Microwave, Inc. The purchase price of $27,000 is subject to adjustment based 
on closing net assets. The Company used cash on hand to fund the purchase 
price. 

   On December 22, 1997, the Company signed a definitive agreement to 
purchase substantially all the assets and liabilities of the Ocean Systems 
division of AlliedSignal Inc. The purchase price of $67,500, subject to 
adjustment based on closing net working capital, will be financed through 
cash on hand and/or borrowings available under the Senior Credit Facilities. 

   In February 1998, the Company entered into a definitive agreement to 
purchase the assets of ILEX Systems ("ILEX") for $51,900 in cash and 
additional consideration based on post-acquisition performance of ILEX. 

   The acquisition of ILEX and Ocean Systems are expected to close during the 
first quarter of 1998. The company plans to finance the purchase prices using 
its cash on hand and available borrowings under its revolving credit 
facility. 

   
   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 of Holdings.

                        REPORT OF INDEPENDENT AUDITORS 

Board of Directors of 
 L-3 Communications Holdings, Inc.: 

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

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

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

1. BACKGROUND AND DESCRIPTION OF BUSINESS 

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

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

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

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

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

2. BASIS OF PRESENTATION 

BASIS OF COMBINATION 

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

             NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued) 
                            (Dollars in thousands) 

 ALLOCATION OF CORPORATE EXPENSES 

   The amount of corporate office expenses reflected in these financial 
statements has been estimated based primarily on the allocation methodology 
prescribed by government regulations pertaining to government contractors, 
which management of the Businesses believes to be a reasonable allocation 
method. 

INCOME TAXES 

   The Businesses were included in the consolidated Federal income tax return 
and certain combined and separate state and local income tax returns of 
Loral. However, for the purposes of these financial statements, the provision 
for income taxes was allocated based upon reported income before income 
taxes. Such provision was recorded through the advances from (repayments to) 
Loral account. 

INTEREST EXPENSE 

   Interest expense has been allocated to the Businesses by applying Loral's 
weighted average consolidated interest rate to the portion of the beginning 
of the period invested equity account deemed to be financed by consolidated 
debt, which amount has been determined based on Loral's debt to equity ratio 
on such date, except that the acquisition of Wideband Systems has been 
assumed to be fully financed by debt. 

STATEMENTS OF CASH FLOWS 

   The Businesses participated in Loral's cash management system, under which 
all cash was received and payments made by Loral. All transactions between 
the Businesses and Loral have been accounted for as settled in cash on the 
date such transactions were recorded by the Businesses. 

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

CONTRACTS IN PROCESS 

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

   Costs accumulated under long-term contracts include direct costs as well 
as manufacturing, overhead, and for government contracts, general and 
administrative, independent research and development and bid and proposal 
costs. Losses on contracts are recognized when determined. Revisions in 
profit estimates are reflected in the period in which the facts which require 
the revision become known. 

DEPRECIATION AND AMORTIZATION 

   Depreciation is provided primarily on the straight-line method over the 
estimated useful lives of the related assets. Leasehold improvements are 
amortized over the shorter of the lease term or the estimated useful life of 
the improvements. The excess of the cost of purchased businesses over the 
fair value of the net assets acquired is being amortized using a 
straight-line method generally over a 40-year period. 

                              F-43           
<PAGE>
                          LORAL ACQUIRED BUSINESSES 
             NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued) 
                            (Dollars in thousands) 

    The carrying amount of cost in excess of net assets acquired is evaluated 
on a recurring basis. Current and future profitability as well as current and 
future undiscounted cash flows, excluding financing costs, of the underlying 
businesses are primary indicators of recoverability. There were no 
adjustments to the carrying amount of cost in excess of net assets acquired 
resulting from these evaluations during the periods presented. 

USE OF ESTIMATES 

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

NEW ACCOUNTING PRONOUNCEMENTS 

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

   Effective January 1, 1994, the Businesses adopted Statement of Financial 
Accounting Standards No. 112, "Employers' Accounting for Postemployment 
Benefits" ("SFAS 112"). SFAS 112 requires that the costs of benefits provided 
to employees after employment but before retirement be recognized on an 
accrual basis. The adoption of SFAS 112 did not have a material impact on the 
results of operations of the Businesses. 

4. ACQUISITIONS 

   Effective May 1, 1995, Loral acquired substantially all the assets and 
liabilities of the Defense Systems operations of Unisys Corporation, which 
included the Wideband Systems Division. The acquisition has been accounted 
for as a purchase. As such, the accompanying combined financial statements 
reflect the results of operations of the Wideband Systems Division from the 
effective date of acquisition, including the amortization of an allocated 
portion of cost in excess of net assets acquired resulting from the 
acquisition. Such allocation was based on the sales and profitability of the 
Wideband Systems Divisions relative to the aggregate sales and profitability 
of the defense systems operations acquired by Loral. The assets and 
liabilities recorded in connection with the purchase price allocation were 
$240,525 and $25,598, respectively. 

   Had the acquisition of the Wideband Systems Division occurred on January 
1, 1995, the unaudited pro forma sales and net income for the year ended 
December 31, 1995 would have been $524,355 and $504,780, respectively. The 
results, which are based on various assumptions, are not necessarily 
indicative of what would have occurred had the acquisition been consummated 
as of January 1, 1995.

6. INCOME TAXES 

   The provision for income taxes was calculated by applying Loral's 
statutory tax rates to the reported pre-tax book income after considering 
items that do not enter into the determination of taxable income and tax 
credits reflected in the consolidated provision which are related to the 
Businesses. It is estimated that deferred income taxes represent 
approximately $714,000 and $2,857,000 of the provisions for income taxes 
reflected in these financial statements for the three months ended March 31, 
1996 and the year ended December 31, 1995. The principal components of 
deferred income taxes are contract accounting methods, property plant and 
equipment, goodwill amortization, and timing of accruals. Substantially all 
of the Businesses' income is from domestic operations. 

   The following is a reconciliation of the statutory rate to the effective 
tax rates reflected in the financial statements:

 8. COMMITMENTS AND CONTINGENCIES 

   The Businesses lease certain facilities and equipment under agreements 
expiring at various dates through 2011. Leases covering major items of real 
estate and equipment contain renewal and/or purchase options which may be 
exercised by the Businesses. Rent expense for the three months ended March 
31, 1996 was $1,063. Rent expense for the year ended December 31, 1995 was 
$4,276. 

   Management is continually assessing its obligations with respect to 
applicable environmental protection laws. While it is difficult to determine 
the timing and ultimate cost to be incurred by the Businesses in order to 
comply with these laws, based upon available internal and external 
assessments, the Businesses believe that even without considering potential 
insurance recoveries, if any, there are no environmental loss contingencies 
that, individually or in the aggregate, would be material to the Businesses' 
operations. The Businesses accrue for these contingencies when it is probable 
that a liability has been incurred and the amount of the loss can be 
reasonably estimated. The Businesses believe that it has adequately accrued 
for future expenditures in connection with environmental matters and that 
such expenditures will not have a material adverse effect on its financial 
position or results of operations. 

   There are a number of lawsuits or claims pending against the Businesses 
and incidental to its business. However, in the opinion of management, the 
ultimate liability on these matters, if any, will not have a material adverse 
effect on the financial position or results of operations of the Businesses. 

9. PENSIONS AND OTHER EMPLOYEE BENEFITS 

PENSIONS 

   The Businesses participate in various Loral-sponsored pension plans both 
contributory and non-contributory covering certain employees. Eligibility for 
participation in these plans varies, and benefits are generally based on 
members' compensation and years of service. Loral's funding policy was 
generally to contribute in accordance with cost accounting standards that 
affect government contractors, subject to the Internal Revenue code and 
regulations thereon. Since the aforementioned pension arrangements were part 
of certain Loral defined benefit or defined contribution plans, no separate 
actuarial data was available for the Businesses. The Businesses have been 
allocated their share of pension costs based upon participation employee 
headcount. Net pension expense, which approximates the amount funded, 
included in the accompanying financial statements was $1,234 and $4,391 for 
the three months ended March 31, 1996 and the year ended December 31, 1995, 
respectively. 

POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS 

   In addition to participating in Loral-sponsored pension plans, the 
Businesses provide certain health care and life insurance benefits for 
retired employees and dependents at certain locations. Participants are 
eligible for these benefits when they retire from active service and meet the 
pension plan eligibility requirements. These benefits are funded primarily on 
a pay-as-you-go basis with the retiree generally paying a portion of the cost 
through contributions, deductibles and coinsurance provisions. Since the 
aforementioned postretirement benefits were part of certain Loral 
postretirement arrangements, no separate actuarial data is available for the 
Businesses. The Businesses have been allocated postretirement benefit costs 
based upon participant employee headcount. Post-retirement benefits costs 
included in the accompanying financial statements were $402 and $1,646 for 
the three months ended March 31, 1996 and the year ended December 31, 1995, 
respectively. 

EMPLOYEE SAVINGS PLANS 

   Under various employee savings plans sponsored by Loral, the Businesses 
matched the contributions of participating employees up to a designated 
level. The extent of the match, vesting terms and the form

of the matching contribution vary among the plans. Under these plans, the 
matching contributions, in cash, common stock or both, for the three months 
ended March 31, 1996 and the year ended December 31, 1995 were $634 and 
$1,879, respectively.

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.

                  NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 
                 SIX MONTHS ENDED DECEMBER 31, 1996 AND 1997 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

BASIS OF PRESENTATION 

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

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

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

USE OF ESTIMATES; RISKS AND UNCERTAINTIES 

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

INVENTORIES AND COST OF PRODUCTS SOLD 

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

3. CORPORATE ALLOCATIONS 

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

   No interest is allocated by CMI to the Division. 

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

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

</TABLE>

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

4. RESTRUCTURING 

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

 5. OTHER 

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

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

                        REPORT OF INDEPENDENT AUDITORS 

The Board of Directors 
California Microwave, Inc. 

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

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

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

                          CALIFORNIA MICROWAVE, INC. 
                        NOTES TO FINANCIAL STATEMENTS 
                   YEARS ENDED JUNE 30, 1995, 1996 AND 1997 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

BASIS OF PRESENTATION 

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

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

USE OF ESTIMATES; RISKS AND UNCERTAINTIES 

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

CASH AND CASH EQUIVALENTS 

   The Division participates in CMI's centralized cash management function; 
accordingly, the Division does not maintain separate cash accounts, other 
than payroll and foreign subsidiary accounts, which are deemed insignificant, 
and its cash disbursements and collections are settled through Division 
equity. 

INVENTORIES AND COST OF PRODUCTS SOLD 

   Inventories are recorded at the lower of cost or market. Project 
inventories are transferred to cost of products sold at the time revenue is 
recognized based on the estimated total manufacturing costs and total 
contract prices under each contract. Losses on contracts are recognized in 
full when the losses become determinable. During the year ended June 30, 
1995, the Division recognized losses of approximately $2,800,000 on such 
contracts. The cost of other inventories is generally based on standard costs 
which approximate actual costs determined by the first-in, first-out method. 

PROPERTY, PLANT AND EQUIPMENT 

   Property, plant and equipment are carried at cost, less accumulated 
depreciation and amortization. Depreciation and amortization charges are 
computed using the straight-line method based on the estimated useful lives 
of the related assets. 

INTANGIBLE ASSETS OF BUSINESS ACQUIRED 

   During 1997, CMI wrote off $1,888,000 of purchased intangible assets, 
principally goodwill, relating to the original acquisition of STS by CMI, 
which was pushed down to the Division's books. 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.

10. 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 
$1,477,000, $1,555,000 and $1,663,000 in 1995, 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 $944,000, $1,437,000 and $1,856,000 in 
1995, 1996, and 1997, respectively.

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

11. RELATED PARTY TRANSACTIONS 

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

12. RESTRUCTURING 

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

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

13. SUBSEQUENT EVENTS 

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

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

                       ILEX SYSTEMS, INC. AND SUBSIDIARY 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
                              DECEMBER 31, 1997 

(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES 

DESCRIPTION OF BUSINESS 

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

PRINCIPLES OF CONSOLIDATION 

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

REVENUE RECOGNITION 

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

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

CASH EQUIVALENTS 

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

FAIR VALUE OF FINANCIAL INSTRUMENTS 

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

INVENTORIES 

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

PROPERTY, PLANT, AND EQUIPMENT 

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

GOODWILL 

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

                              F-72           
<PAGE>
 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-73           
<PAGE>
    The provision for income taxes for the year ended December 31, 1997, 
differs from the federal statutory rate, primarily due to the flow through 
nature of income tax liability to the shareholders and reduction of the 
federal and partial state deferred income tax assets and liabilities as of 
December 31, 1996, resulting from the S corporation election as follows: 

<TABLE>
<CAPTION>
<S>                                        <C>
Federal income tax statutory rate ........    34.0% 
State income tax rate.....................     2.2 
Benefit of federal S corporation 
 election.................................   (28.8) 
                                           -------- 
                                               7.4% 
                                           ======== 
</TABLE>

   The gross deferred tax assets were $13,000 as of December 31, 1997, 
consisting of the state deferred income tax assets and liabilities for those 
states who do not recognize S corporation status. Management considers 
realization of the net deferred tax assets more likely than not due to 
continued profitability of the Company and significant carryback 
opportunities. 

(5) EMPLOYEE BENEFIT PLANS 

   The Company has two Section 401(k) retirement savings plans (the Plans). 
Under the terms of the Plans, employees may make contributions based on a 
percentage of eligible earnings. Company contributions to the Plans are 
discretionary and totaled $359,718 in 1997. 

(6) STOCK OPTION PLAN 

   The Company has 100,000 shares of common stock reserved for issuance under 
its 1992 Incentive Stock Option Plan (the "Plan"). Under the Plan, the 
Company may grant options to employees, officers, and directors. Options are 
granted at prices not less than the fair market value of the Company's common 
stock as determined by the Board of Directors on the grant date. Options vest 
ratably over 48 months and expire 49 months from the date of grant. 

   The Company applies Accounting Principles Board Opinion No. 25 (APB 25) in 
accounting for its stock options. The exercise price for stock options 
granted to employees in 1997 equaled the fair value of the Company's common 
stock at the date of grant. Accordingly, in accordance with APB 25, no 
compensation expense was recognized by the Company. 

   For purposes of pro forma disclosures required by Statement of Financial 
Accounting Standards No. 123 (SFAS 123), the compensation cost of the 
options, based on their estimated fair values, is amortized to expense over 
the vesting periods of the options. The Company's net income for the year 
ended December 31, 1997 would have reduced to the pro forma amounts indicated 
below: 

<TABLE>
<CAPTION>
<S>             <C>
 Net income: 
 As reported  .  $6,854,742 
                ============ 
 Pro forma ....  $6,838,958 
                ============ 
</TABLE>

   On January 1, 1997, the Company had no options outstanding. In July 1997, 
the Company granted 25,000 options at an exercise price of $17.50, all of 
which were outstanding but not exercisable as of December 31, 1997. 

   The weighted-average grant-date fair value of options granted during the 
year ended December 31, 1997 was $3.05 per option. The weighted-average 
remaining contract life of the Company's outstanding stock options was 3.5 
years at December 31, 1997. 

   Pro forma information regarding net income as required by SFAS 123 has 
been determined as if the Company had accounted for its employee stock 
options under the fair value method. The fair value for the options was 
estimated at the date of grant using the minimum value method prescribed in 
SFAS 123, which does not consider the expected volatility of the Company 
stock price, with the following weighted-average assumptions for 1997: risk 
free interest rate of 6.06%; dividend yield of 0%; and weighted-average 
expected option life of 3.25 years.

 (7) COMMITMENTS 

   The Company leases certain facilities under operating leases that expire 
at various dates through 2001. The Company in turn subleases some of these 
facilities. As of December 31, 1997, future minimum lease payments under 
noncancelable operating leases, exclusive of the sublease rentals, are as 
follows:

</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

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-82

                    NOTES TO COMBINED FINANCIAL STATEMENTS

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

                    NOTES TO COMBINED FINANCIAL STATEMENTS

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.

                            (DOLLARS IN THOUSANDS) 

 ALLOCATION OF CORPORATE EXPENSES 

   The amount of allocated corporate expenses reflected in these combined 
financial statements has been estimated based primarily on an allocation 
methodology prescribed by government regulations pertaining to government 
contractors. Corporate expenses allocated to Ocean Systems were $2,258 for 
the year ended December 31, 1997, and are included in general and 
administrative expense in the accompanying combined statement of operations. 

PENSIONS 

   Certain of the Company's employees participate in various AlliedSignal 
sponsored pension plans covering certain employees. Eligibility for 
participation in these plans varies, and benefits are generally based on 
employees' compensation and years of service. 

   AlliedSignal funding policy is generally to contribute in accordance with 
cost accounting standards that affect government contractors subject to the 
Internal Revenue code and regulations. Although the aforementioned pension 
arrangements are part of certain AlliedSignal defined benefit plans, separate 
actuarial estimates were made for the portion allocable to the Company. 
Pension expense included in the accompanying combined statement of operations 
was $1,452 for the year ended December 31, 1997. The pension plan liability 
at December 31, 1997 was fully funded. The Company also has a supplemental 
pension plan for highly compensated employees as defined by IRS rules. The 
liability reflected in the accompanying combined balance sheet was $650 at 
December 31, 1997. Pension expense included in the combined statement of 
operations for the supplemental pension plan was $24 for the year ended 
December 31, 1997. 

   The Company's German employees of ELAC are covered by a separate pension 
plan. Pension costs included the following components for the year ended 
December 31, 1997:

POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS 

   In addition to participating in AlliedSignal pension plans, employees of 
OS are provided varying levels of health care and life insurance benefits for 
retired employees and dependents. Participants are eligible for these 
benefits when they retire from active service and meet the pension plan 
eligibility requirements. These benefits are funded primarily on a 
pay-as-you-go basis with the retiree generally paying of the cost through 
contributions, deductibles and coinsurance provisions. 

   Although the aforementioned postretirement benefits are part of certain 
AlliedSignal postretirement arrangements, separate actuarial estimates were 
made for the portion allocable to the Company. The weighted average discount 
rate utilized in determining the accumulated postretirement benefit 
obligation was 7.25% for 1997. Net postretirement benefit costs included in 
the combined statements of operations was $1,072 for the year ended December 
31, 1997. 

   The net postretirement benefit costs for 1997 included the following 
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 

   Net inventories are comprised of the following components at December 31, 
1997:

                                        ========= 
</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.

of the International Offering. 

   Prior to the Offering, there has been no public market for the Common 
Stock of Holdings. It is currently estimated that the initial public offering 
price will be between $18.00 and $20.00 per share. See "Underwriting" for a 
discussion of factors to be considered in determining the initial public 
offering price. The Common Stock has been approved for listing, subject to 
notice of issuance, on the New York Stock Exchange (the "NYSE") under the 
symbol    . 
    

   Concurrently with the Common Stock Offering, L-3 Communications 
Corporation, a wholly-owned subsidiary of Holdings, is publicly offering (the 
"Notes Offering" and, together with the Common Stock Offering, the 
"Offerings") $150.0 million aggregate principal amount of its    % Senior 
Subordinated Notes due 2008 (the "Notes"). Prior to the consummation of the 
Common Stock Offering, affiliates of Lehman Brothers Inc. own 49.0% of the 
outstanding Common Stock of Holdings. See "Ownership of Capital Stock".

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS. 

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

     (i)  permissive indemnification for expenses (including attorneys' fees), 
    judgments, fines and amounts paid in settlement actually and reasonably 
    incurred by designated persons, including directors and officers of a 
    corporation, in the event such persons are parties to litigation other 
    than stockholder derivative actions if certain conditions are met; 

     (ii)  permissive indemnification for expenses (including attorneys' fees) 
    actually and reasonably incurred by designated persons, including 
    directors and officers of a corporation, in the event such persons are 
    parties to stockholder derivative actions if certain conditions are met; 

     (iii) mandatory indemnification for expenses (including attorneys' fees) 
    actually and reasonably incurred by designated persons, including 
    directors and officers of a corporation, in the event such persons are 
    successful on the merits or otherwise in defense of litigation covered by 
    (i) and (ii) above; and 

     (iv) that the indemnification provided for by Section 145 is not deemed 
    exclusive of any other rights which may be provided under any by-law, 
    agreement, stockholder or disinterested director vote, or otherwise. 

   In addition to the indemnification provisions of the DGCL described above, 
the Registrant's Certificate of Incorporation (the "Certificate of 
Incorporation") provides that the Registrant shall, to the fullest extent 
permitted by the DGCL, (i) indemnify its officers and directors and (ii) 
advance expenses incurred by such officers or directors in relation to any 
action, suit or proceeding. 

   The Registrant's Bylaws (the "Bylaws") require the advancement of expenses 
to an officer or director (without a determination as to his conduct) in 
advance of the final disposition of a proceeding if such person furnishes a 
written affirmation of his good faith belief that he has met the applicable 
standard of conduct and furnishes a written undertaking to repay any advances 
if it is ultimately determined that he is not entitled to indemnification. In 
connection with proceedings by or in the right of the Registrant, the Bylaws 
provide that indemnification shall include not only reasonable expenses, but 
also judgments, fines, penalties and amounts paid in settlement. The Bylaws 
provide that the Registrant may, subject to authorization on a case-by-case 
basis, indemnify and advance expenses to employees or agents to the same 
extent as a director or to a lesser extent (or greater, as permitted by law) 
as determined by the Board of Directors. 

                               II-1           
<PAGE>
    The Bylaws purport to confer upon officers and directors contractual 
rights to indemnification and advancement of expenses as provided therein. 

   The Certificate of Incorporation limits the personal liability of 
directors to the Registrant or its stockholders for monetary damages for 
breach of the fiduciary duty as a director, other than liability as a 
director (i) for breach of duty of loyalty to the Registrant or its 
stockholders, (ii) for acts or omissions not in good faith or which involve 
intentional misconduct or a knowing violation of law, (iii) under Section 174 
of the DGCL (certain illegal distributions) or (iv) for any transaction for 
which the director derived an improper personal benefit. 

   The Registrant maintains officers' and directors' insurance covering 
certain liabilities that may be incurred by officers and directors in the 
performance of their duties. 

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES. 

   Since April 30, 1997, Holdings has sold unregistered securities in the 
amounts, at the times and for the aggregate amounts of consideration listed 
below. The securities were sold directly by Holdings and did not involve any 
underwriter. Holdings considers these securities to have been offered and 
sold in transactions not involving any public offering and, therefore, to be 
exempted from registration under Section 4(2) of the Securities Act. The 
following assumes the conversion of Class B Common Stock into Common Stock 
which will occur upon the consummation of the Common Stock Offering. 

   On April 30, 1997, Holdings issued 10,020,000 shares of Common Stock to 
the Lehman Partnership and 6,980,000 shares of Common Stock to Lockheed 
Martin for aggregate consideration of $109,990,000. On April 30, 1997, 
Holdings issued 1,500,000 shares of Common Stock to each of Messrs. Lanza and 
LaPenta for aggregate consideration of $15,000,000. Of such shares, 226,000 
shares have been repurchased by Holdings. 

   On December 19, 1997, Holdings issued 226,000 shares of Common Stock to 21 
management investors for aggregate consideration of $1,462,220. 

   On March 2, 1998, Holdings issued 228,571 shares of Common Stock to each 
of Messrs. Lanza and LaPenta upon exercise of the first year of vesting under 
their respective stock option agreements for aggregate consideration of 
$2,957,700.

ITEM 17. UNDERTAKINGS. 

   (a) The undersigned Registrant hereby undertakes to provide to the 
Underwriters at the closing specified in the Underwriting Agreements, 
certificates in such denominations and registered in such names as required 
by the Underwriters to permit prompt delivery to each purchaser. 

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

   (c) The undersigned Registrant hereby undertakes that: 

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

     (2) For the purpose of determining any liability under the Securities Act 
    of 1933, each post-effective amendment that contains a form of prospectus 
    shall be deemed to be a new registration statement relating to the 
    securities offered therein, and the offering of such securities at that 
    time shall be deemed to be the initial bona fide offering thereof.

Lender severally agrees to make the loans described in this Section 2.1(a) as
applicable to the Borrower.

               (i) Tranche A Term Loans. Each Tranche A Term Lender severally
          agrees to make a term loan to the Borrower on the Closing Date in an
          aggregate principal amount which does not exceed the amount of such
          Lender's Tranche A Term Loan Commitment. Amounts borrowed under this

               (ii) Tranche B Term Loans. Each Tranche B Term Lender severally
          agrees to make a term loan to the Borrower on the Closing Date in an
          aggregate principal amount which does not exceed the amount of such
          Lender's Tranche B Term Loan Commitment. Amounts borrowed under this
          subsection 2.1(a)(ii) and subsequently repaid may not be reborrowed.

               (iii) Tranche C Term Loans. Each Tranche C Term Lender severally
          agrees to make a term loan to the Borrower on the Closing Date in an
          aggregate principal amount which does not exceed the amount of such
          Lender's Tranche C Term Loan Commitment. Amounts borrowed under this
          subsection 2.1(a)(iii) and subsequently repaid may not be reborrowed.

               (iv) Revolving Credit Loans. Each Revolving Credit Lender
          severally agrees to make revolving credit loans to the Borrower, from
          time to time during the Commitment Period, in an aggregate principal
          amount at any one time outstanding which, when added to the aggregate
          principal amount of outstanding Swing Line Loans made by such Lender
          (or in which such Lender has purchased a participation) and such
          Lender's Revolving Credit Commitment Percentage of the then
          outstanding L/C Obligations, does not exceed the amount of such
          Lender's Revolving Credit Commitment. During the Commitment Period,
          the Borrower may use the Revolving Credit Commitments by borrowing,
          prepaying the Revolving Credit Loans, in whole or in part, and
          reborrowing, all in accordance with the terms and conditions hereof.

          (b) (i) Subject to the terms and conditions hereof, the Swing Line
Lender agrees to make swing line loans (individually, a "Swing Line Loan";

                                       21

<PAGE>





time during the Commitment Period in an aggregate principal amount at any one
time outstanding not to exceed $10,000,000; provided, that no Swing Line Loan
shall be made if, after giving effect thereto and to the simultaneous use of
the proceeds thereof, the aggregate principal amount of Revolving Credit Loans
then outstanding plus the aggregate principal amount of Swing Line Loans then
outstanding, plus the aggregate amount of L/C Obligations then outstanding
would exceed the Revolving Credit Commitments of the Revolving Credit Lenders.
Amounts borrowed by the Borrower under this subsection 2.1(b) may be repaid
and, through but excluding the Termination Date, reborrowed. All Swing Line
Loans shall be made as Base Rate Loans and may not be converted into Eurodollar
Loans. In order to borrow a Swing Line Loan, the Borrower shall give the Swing
Line Lender, with a copy to the Administrative Agent, irrevocable notice (which
notice must be received by the Swing Line Lender prior to 12:00 Noon, New York
City time) on the requested Borrowing Date specifying the amount of the
requested Swing Line Loan which shall be in a minimum amount of $500,000 or
whole multiples of $100,000 in excess thereof. The proceeds of the Swing Line
Loan will be made available by the Swing Line Lender to the Borrower at the
office of the Swing Line Lender by crediting the account of the Borrower at
such office with such proceeds.

               (ii) The Swing Line Loans shall be evidenced by a promissory
note of the Borrower, substantially in the form of Exhibit A-5 (the "Swing Line
Note"), with appropriate insertions, payable to the order of the Swing Line
Lender and representing the obligation of the Borrower to pay the unpaid
principal amount of the Swing Line Loans, with interest thereon as prescribed
in subsection 2.9. The Swing Line Note shall (i) be dated the Closing Date,
(ii) be stated to mature on the Termination Date and (iii) bear interest,
payable on the dates specified in 2.9, for the period from the date thereof to
the Termination Date on the unpaid principal amount thereof from time to time
outstanding at the applicable interest rate per annum specified in subsection
2.9.

               (iii) The Swing Line Lender, at any time in its sole and
absolute discretion, may on behalf of the Borrower (which hereby irrevocably
directs the Swing Line Lender to act on its behalf) request each Lender,
including the Swing Line Lender, to make a Revolving Credit Loan (which shall
be a Base Rate Loan) in an amount equal to such Lender's Commitment Percentage
with respect to Revolving Credit Loans of such Revolving Credit Loan (the
"Refunded Swing Line Loans") outstanding on the date such notice is given.
Unless any of the events described in subsection 8(f) shall have occurred (in
which event the procedures of subsection 2.1(b)(iv) shall apply) each Lender
shall, not later than 12:00 P.M., New York City time, on the Business Day next
succeeding the date on which such notice is given, make available to the Swing
Line Lender in immediately available funds the amount equal to the Revolving
Credit Loan to be made by such Lender. The proceeds of such Revolving Credit
Loans shall be immediately applied to repay the Refunded Swing Line Loans. Upon
any request by the Swing Line Lender to the Lender pursuant to this subsection
2.1(b)(iii), the Administrative Agent shall promptly give notice to the
Borrower of such request.

               (iv) If prior to the making of a Revolving Credit Loan pursuant
to subsection 2.1(b)(iii) one of the events described in subsection 8(f) shall
have occurred, each Lender will, on the date such Loan was to have been made,
purchase an undivided participating interest in the Swing Line Loans in an
amount equal to its Commitment Percentage with respect to



                                       22

<PAGE>





Revolving Credit Loans.  Each Lender will immediately transfer to the Swing
Line Lender, in immediately available funds, the amount of its participation.

               (v) Whenever, at any time after the Swing Line Lender has
received from any Lender such Lender's participating interest in a Swing Line
Loan, the Swing Line Lender receives any payment on account thereof, the Swing
Line Lender will distribute to such Lender its participating interest in such
amount (appropriately adjusted, in the case of interest payments, to reflect
the period of time during which such Lender's participating interest was
outstanding and funded); provided, however, that in the event that such payment
received by the Swing Line Lender is required to be returned, such Lender will
return to the Swing Line Lender any portion thereof previously distributed by
the Swing Line Lender to it.

               (vi) Each Lender's obligation to purchase participating
interests pursuant to subsection 2.1(b)(iv) shall be absolute and unconditional
and shall not be affected by any circumstance, including, without limitation,

Lender or the Borrower may have against the Swing Line Lender, any other Lender
or anyone else for any reason whatsoever, (b) the occurrence or continuance of
any Default or Event of Default; (c) any adverse change in the condition

the Borrower or any other Lender; or (e) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing.

Loans may from time to time be (i) Eurodollar Loans, (ii) Base Rate Loans or
(iii) a combination thereof, as determined by the Borrower and notified to the
Administrative Agent in accordance with subsections 2.2 and 2.7, provided that
no Revolving Credit Loan shall be made as a Eurodollar Loan after the day that
is one month prior to the Termination Date with respect to such Loan.

          2.2 Procedure for Borrowing. The Borrower may borrow under the
Commitments during the Commitment Period on any Business Day, provided that the
Borrower shall give the Administrative Agent irrevocable notice (which notice

borrowing under the Commitments shall be in an amount equal to (x) in the case

multiple of $500,000 in excess thereof (or, if the then Available Commitments
are less than $2,000,000, such lesser amount), (y) in the case of Swing Line
Loans, as provided in subsection 2.1(b)(i) and (z) in the case of Eurodollar

receipt of any such notice from the Borrower, the Administrative Agent shall
promptly notify each Lender thereof. Each Lender will make the amount of its

account of the Borrower at the office of the Administrative Agent specified in

Administrative Agent. Such borrowing will then be made available to the
Borrower by the Administrative Agent crediting the account of the Borrower on
the books of such office with the aggregate of the amounts made available to
the Administrative Agent by the Lenders and in like funds as received by the
Administrative Agent. All notices given by the Borrower under this subsection
2.2 may be made by telephonic notice promptly confirmed in writing.

          2.3 Commitment Fee. The Borrower agrees to pay to the Administrative
Agent for the account of each Revolving Credit Lender a commitment fee for the
period from and including the first day of the Commitment Period to and

Credit Lender during the period for which payment is made, payable quarterly in

dates to occur after the date hereof.

Borrower shall have the right, upon not less than three Business Days' written
notice to the Administrative Agent, to terminate the Revolving Credit
Commitments or, from time to time, to reduce the amount of the Revolving Credit
Commitments ratably among the Revolving Credit Lenders; provided that no such
termination or reduction shall be permitted if, after giving effect thereto and
to any prepayments of the Revolving Credit Loans made on the effective date
thereof, the aggregate principal amount of the Revolving Credit Loans then
outstanding, when added to the then outstanding L/C Obligations and the
outstanding Swing Line Loans, would exceed the Revolving Credit Commitments

become due and payable pursuant to Section 8) (i) for the account of each
Revolving Credit Lender the then unpaid principal amount of each Revolving
Credit Loan of such Lender and (ii) for the account of the Swing


                                       27

<PAGE>




Line Lender (and each other Revolving Credit Lender that has purchased a
participation in then outstanding Swing Line Loans) the then unpaid principal
amount of Swing Line Loans.

                 (e) Interest. The Borrower hereby further agrees to pay
interest on the unpaid principal amount of the Loans from time to time
outstanding from the date such Loans are made until payment in full thereof at
the rates per annum, and on the dates, set forth in subsection 2.9.

                 (f) Recording. Each Lender shall maintain in accordance with
its usual practice an account or accounts evidencing indebtedness of the
Borrower to such Lender resulting from each Loan of such Lender from time to
time, including the amounts of principal and interest payable and paid to such
Lender from time to time under this Agreement.

                 (g) Register. The Administrative Agent shall maintain the
Register pursuant to subsection 10.6(d), and a subaccount therein for each
Lender, in which shall be recorded (i) the amount of each Loan and each
Obligation evidenced by a Note made hereunder, the Type thereof, whether each
such Loan is a Base Rate Loan or a Eurodollar Loan and each Interest Period
applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder
and (iii) both the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

                 (h) Prima Facie Evidence. The entries made in the Register and
the accounts of each Lender maintained pursuant to subsection 2.5(g) shall, to
the extent permitted by applicable law, be prima facie evidence of the
existence and amounts of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Lender or the Administrative Agent
to maintain the Register or any such account, or any error therein, shall not
in any manner affect the obligation of the Borrower to repay (with applicable
interest) the Loans made to the Borrower by such Lender in accordance with the
terms of this Agreement.

                 (i) Notes. The Borrower agrees that the Borrower will execute
and deliver to each Lender a promissory note of the Borrower evidencing (i) the
Tranche A Term Loans of such Lender, substantially in the form of Exhibit A-1
with appropriate insertions as to date and principal amount (a "Tranche A Term
Note"), (ii) the Tranche B Term Loans of such Lender, substantially in the form
of Exhibit A-2 with appropriate insertions as to date and principal amount (a
"Tranche B Term Note"), (iii) the Tranche C Term Loans of such Lender
substantially in the form of Exhibit A-3 with appropriate insertions as to date
and principal amount (a "Tranche C Term Note") and (iv) the Revolving Credit
Loans of such Lender, substantially in the form of Exhibit A-4 with appropriate
insertions as to date and principal amount ("Revolving Credit Note"). A Note
and the Obligation evidenced thereby may be assigned or otherwise transferred
in whole or in part only by registration of such assignment or transfer of such
Note and the Obligation evidenced thereby in the Register (and each Note shall
expressly so provide). Any assignment or transfer of all or part of an
Obligation evidenced by a Note shall be registered in the Register only upon
surrender for registration of assignment or transfer of the Note evidencing
such Obligation, duly endorsed by (or accompanied by a written instrument of
assignment or transfer duly executed by) the holder thereof, and thereupon one
or more new Notes shall be issued to the designated Assignee and the old Note
shall be returned by the Administrative Agent to the Borrower marked
"cancelled." No

assignment of a Note and the Obligation evidenced thereby shall be effective
unless it shall have been recorded in the Register by the Administrative Agent
as provided in this subsection 2.5(i).

                 2.6 Optional Prepayments; Mandatory Prepayments and Reduction
of Commitments. (a) Subject to subsection 2.16, the Borrower may at any time
and from time to time prepay any Loans, in whole or in part, without premium or
penalty, upon irrevocable notice to the Administrative Agent prior to 11:00
A.M., New York City time, three Business Days prior to the date of prepayment,
specifying the date and amount of prepayment, the Type of Loan to be prepaid
(which loans shall be prepaid on a pro rata basis among the applicable Lenders)
and whether the prepayment is of Eurodollar Loans, Base Rate Loans or a
combination thereof, and, if of a combination thereof, the amount allocable to
each. Upon receipt of any such notice the Administrative Agent shall promptly
notify each applicable Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified
therein, together with any amounts payable pursuant to subsection 2.16. Partial
prepayments shall be in an aggregate principal amount of $2,000,000 or a whole
multiple of $1,000,000 in excess thereof.

                 (b) (i) If, subsequent to the Closing Date, Holdings or any of
its Subsidiaries shall incur or permit the incurrence of any Indebtedness
(other than Indebtedness permitted pursuant to subsection 7.2) 100% of the Net
Proceeds thereof shall be promptly applied toward the prepayment of the Loans
and permanent reduction of the Commitments as set forth in clause (iv) of this
subsection 2.6(b). Nothing in this paragraph (b) shall be deemed to permit any
Indebtedness not permitted by subsection 7.2.

                    (ii) If, subsequent to the Closing Date, Holdings or any of
its Subsidiaries shall receive Net Proceeds from any Asset Sale, such Net
Proceeds shall be promptly applied toward the prepayment of the Loans and
permanent reduction of the Commitments as set forth in clause (iv) of this
subsection 2.6(b); provided that Net Proceeds from any Asset Sales shall not be
required to be so applied to the extent that such Net Proceeds are used by the
Borrower or such Subsidiary to acquire assets to be employed in the business of
the Borrower or its Subsidiaries within 365 days of receipt thereof, but if
such Net Proceeds are not so used, 100% of such Net Proceeds shall be applied
toward the prepayment of the Loans and the permanent reduction of the
Commitments as set forth in clause (iv) of this subsection 2.6(b) on the
earlier of (x) the 366th day after receipt of such Net Proceeds and (y) the
date on which the Borrower has determined that such Net Proceeds shall not be
so used.

                   (iii) If there is Excess Cash Flow for any fiscal year and
the Debt Ratio as of the last day of such fiscal year is greater than 3.5 to
1.0, 75% of such Excess Cash Flow shall be applied toward the prepayment of the
Loans and the permanent reduction of the Commitments as set forth in clause
(iv) of this subsection 2.6(b) on the Excess Cash Flow Payment Date for such
fiscal year. If there is Excess Cash Flow for any fiscal year and the Debt
Ratio as of the last day of such fiscal year is less than or equal to 3.5 to
1.0, 50% of such Excess Cash Flow shall be applied toward the prepayment of the
Loans and the permanent reduction of the Commitments as set forth in clause
(iv) of this subsection 2.6(b) on the Excess Cash Flow Payment Date for such
fiscal year.

                 (iv) Any mandatory prepayments of the Loans pursuant to
subsection 2.6 shall be applied (x) to the Tranche A Term Loans, the Tranche B
Term Loans and the Tranche C Term Loans on a pro rata basis to reduce the
unpaid scheduled installments of principal of each such Tranche of Term Loans
on a pro rata basis, and (y) thereafter to the permanent reduction of the
Revolving Credit Commitment; provided that, in the case of Tranche B Term Loans
and Tranche C Term Loans, so long as any Tranche A Term Loans are outstanding,
each of the Tranche B Term Lenders and the Tranche C Term Lenders shall have
the right to waive such Lender's right to receive any portion of such
prepayment. The Administrative Agent shall notify the Tranche B Term Lenders
and the Tranche C Term Lenders of such receipt and the amount of the prepayment
to be applied to each such Lender's Term Loans; provided, that the Borrower
shall use its reasonable efforts to notify the Tranche B Term Lenders and the
Tranche C Term Lenders of such waivable mandatory prepayment three (3) Business
Days prior to the payment to the Administrative Agent of such waivable
mandatory prepayment (it being understood that the Borrower shall have no
liabilities for failing to so notify such Lenders). In the event any such
Tranche B Term Lender or Tranche C Term Lender desires to waive such Lender's
right to receive any such waivable mandatory prepayment, such Lender shall so
advise the Administrative Agent no later than the close of business on the
Business Day immediately following the date of such notice from the
Administrative Agent. In the event that any such Lender waives such Lender's
right to any such waivable mandatory prepayment, the Administrative Agent shall
apply 50% of the amount so waived by such Lender to prepay the Tranche A Term
Loans to reduce unpaid scheduled installments of principal of the Tranche A
Term Loans on a pro rata basis. The Administrative Agent shall return the
remainder of the amount so waived by such Lender to the Borrower. Revolving
Credit Commitment reductions made pursuant to subsections 2.6(b)(i), (ii) and
(iii) shall be applied to each Lender's Revolving Credit Commitment on a pro
rata basis and shall reduce permanently such Commitments.

                 (v) If after giving effect to any reduction of the Revolving
Credit Commitments under subsection 2.4, 2.5 or 2.6 the aggregate outstanding
principal amount of Swing Line Loans plus the aggregate outstanding principal
amount of Revolving Credit Loans plus the aggregate outstanding amount of L/C
Obligations shall exceed the aggregate amount of the Revolving Credit
Commitments, such reduction shall be accompanied by prepayment in the amount of
such excess to be applied (x) first, to the outstanding Swing Line Loans and
(y) second, to outstanding Revolving Credit Loans (in each case, together with
any amounts payable under subsection 2.16)); provided that if the aggregate
principal amount of Swing Line Loans and Revolving Credit Loans then
outstanding is less than the amount of such excess (because Letters of Credit
constitute a portion of such excess), the Borrower shall immediately, without
notice or demand, to the extent of the balance of such excess, replace
outstanding Letters of Credit and/or deposit an amount (but in no event greater
than such balance) in a cash collateral account satisfactory to the
Administrative Agent established for the benefit of the Revolving Credit
Lenders.

                 2.7 Conversion and Continuation Options. (a) The Borrower may
elect from time to time to convert Eurodollar Loans to Base Rate Loans, by
giving the Administrative Agent prior irrevocable notice of such election on or
before 11:00 A.M. New York City time, on the Business Day immediately preceding
the date of the proposed conversion and of the amount and Type of Loan to be
converted, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto.


                                       30

<PAGE>





The Borrower may elect from time to time to convert Base Rate Loans (other than
Swing Line Loans) to Eurodollar Loans by giving the Administrative Agent prior
irrevocable notice of such election on or before 11:00 A.M., New York City
time, on the third Business Day immediately preceding the date of the proposed
conversion and of the amount and Type of Loan to be converted. Any such notice
of conversion to Eurodollar Loans shall specify the length of the initial
Interest Period or Interest Periods therefor. Upon receipt of any such notice
the Administrative Agent shall promptly notify each applicable Lender thereof.
All or any part of outstanding Eurodollar Loans and Base Rate Loans may be
converted as provided herein, provided that (i) no Loan may be converted into a
Eurodollar Loan when any Event of Default has occurred and is then continuing
and (ii) no Loan may be converted into a Eurodollar Loan after the date that is
one month prior to the Termination Date with respect to such Loan.

                 (b) Any Eurodollar Loans may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection
1.1, of the length of the next Interest Period to be applicable to such Loans
and of the amount and Type of Loan to be converted, provided that no Eurodollar
Loan may be continued as such (i) when any Event of Default has occurred and is
then continuing or (ii) after the date that is one month prior to the
Termination Date with respect to such Loan and provided, further, that if the
Borrower shall fail to give such notice or if such continuation is not
permitted such Loans shall be automatically converted to Base Rate Loans on the
last day of such then expiring Interest Period.

                 (c) All notices given by Borrower under this subsection 2.7
may be made by telephonic notice promptly confirmed in writing.

                 2.8 Minimum Amounts and Maximum Number of Tranches. All
borrowings, conversions and continuations of Loans hereunder and all selections
of Interest Periods hereunder shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, the aggregate principal
amount of the Loans comprising each Eurodollar Tranche shall be equal to
$5,000,000 or a whole multiple of $1,000,000 in excess thereof. In no event
shall there be more than 10 Eurodollar Tranches outstanding at any time.

                 2.9 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
day plus the Applicable Margin.

                 (b) Each Base Rate Loan shall bear interest at a rate per
annum equal to the Base Rate plus the Applicable Margin.

                 (c) If all or a portion of (i) any principal of any Loan, (ii)
any interest payable thereon, (iii) any commitment fee or (iv) any other amount
payable hereunder shall not be paid when due (whether at the stated maturity,
by acceleration or otherwise), the principal of the Loans and any such overdue
interest, commitment fee or other amount shall bear interest at a rate per
annum which is (x) in the case of principal, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this subsection plus
2% or (y) in the case of any such overdue interest, commitment fee or other
amount, the rate described in paragraph (b) of this



                                       31

<PAGE>





subsection plus 2%, in each case from the date of such non-payment until such
overdue principal, interest, commitment fee or other amount is paid in full (as
well after as before judgment).

                 (d) Interest shall be payable with respect to each Loan in
arrears on each Interest Payment Date and on the Termination Date with respect
to such Loan, provided that interest accruing pursuant to paragraph (c) of this
subsection shall be payable from time to time on demand.

                 2.10 Computation of Interest and Fees. (a) Interest on Base
Rate Loans and fees shall be calculated on the basis of a 365- (or 366-, as the
case may be) day year for the actual days elapsed; all other interest shall be
calculated on the basis of a 360-day year for the actual days elapsed. The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of each determination of a Eurodollar Rate. Any change in the interest
rate on a Loan resulting from a change in the Base Rate or the Eurocurrency
Reserve Requirements shall become effective as of the opening of business on
the day on which such change becomes effective. The Administrative Agent shall
as soon as practicable notify the Borrower and the Lenders of the effective
date and the amount of each such change in interest rate.

                 (b) Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to subsection
2.9(a) or (c).

                 2.11  Inability to Determine Interest Rate.  If prior to the
first day of any Interest Period:

                 (a) the Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances affecting the eurodollar market, adequate
         and reasonable means do not exist for ascertaining the Eurodollar Rate
         for such Interest Period, or

                 (b) the Administrative Agent shall have received notice from
         the Required Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Loans during such
         Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to
the Borrower and the Lenders as soon as practicable thereafter. If such notice
is given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as Base Rate Loans, (y) any Loans that were to
have been converted on the first day of such Interest Period to Eurodollar
Loans shall be converted to or continued as Base Rate Loans and (z) any
outstanding Eurodollar Loans shall be converted, on the first day of such
Interest Period, to Base Rate Loans. Until such notice has been withdrawn in
writing by the Administrative Agent (which the Administrative Agent agrees to
do when the Administrative Agent has determined, or has been instructed by the
Required Lenders that, the circumstances that prompted the



                                       32

<PAGE>





delivery of such notice no longer exist), no further Eurodollar Loans shall be
made or continued as such, nor shall the Borrower have the right to convert
Loans to Eurodollar Loans.

                 2.12 Pro Rata Treatment and Payments. (a) Each borrowing by
the Borrower from the Revolving Credit Lenders hereunder, each payment by the
Borrower on account of any commitment fee hereunder and any reduction of the
Revolving Credit Commitments of Revolving Credit Lenders shall be made pro rata
according to the respective Commitment Percentages of the Revolving Credit
Lenders. Each payment (including each prepayment) by the Borrower on account of
principal of and interest on any Term Loans or the Revolving Credit Loans shall
be made pro rata according to the respective outstanding principal amounts of
such Loans then held by the Lenders. All payments (including prepayments) to be
made by the Borrower hereunder in respect of any Loan, whether on account of
principal, interest, Reimbursement Obligations, fees or otherwise, shall be
made without set off or counterclaim and shall be made prior to 11:00 A.M., New
York City time, on the due date thereof to the Administrative Agent, for the
account of the Lenders with respect to such Loans, at the Administrative
Agent's office specified in subsection 10.2, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
applicable Lenders promptly upon receipt in like funds as received. If any
payment hereunder becomes due and payable on a day other than a Business Day,
such payment shall be extended to the next succeeding Business Day, and, with
respect to payments of principal, interest thereon shall be payable at the then
applicable rate during such extension.

                 (b) Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make
the amount that would constitute its Commitment Percentage of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent on such
Borrowing Date, and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrower a corresponding amount. If such
amount is not made available to the Administrative Agent by the required time
on the Borrowing Date therefor, such Lender shall pay to the Administrative
Agent, on demand, such amount with interest thereon at a rate equal to the
daily average Federal Funds Effective Rate for the period until such Lender
makes such amount immediately available to the Administrative Agent. A
certificate of the Administrative Agent submitted to any Lender with respect to
any amounts owing under this subsection shall be conclusive in the absence of
manifest error. If such Lender's Commitment Percentage of such borrowing is not
made available to the Administrative Agent by such Lender within three Business
Days of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans hereunder, on demand, from the Borrower. The failure of any
Lender to make any Loan to be made by it shall not relieve any other Lender of
its obligation hereunder to make its Loan on such Borrowing Date.

                 2.13 Illegality. Notwithstanding any other provision herein,
if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be cancelled and (b) such Lender's Loans then outstanding as



                                       33

<PAGE>





Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans
on the respective last days of the then current Interest Periods with respect
to such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of
the then current Interest Period with respect thereto, the Borrower shall pay
to such Lender such amounts, if any, as may be required pursuant to subsection
2.16. If circumstances subsequently change so that any affected Lender shall
determine that it is no longer so affected, such Lender will promptly notify
the Borrower and the Administrative Agent, and upon receipt of such notice, the
obligations of such Lender to make or continue Eurodollar Loans or to convert
Base Rate Loans into Eurodollar Loans shall be reinstated.

                 2.14 Requirements of Law. (a) If the adoption of or any change
in any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                      (i) shall subject any Lender to any tax of any kind
         whatsoever with respect to this Agreement, any Note, any Letter of
         Credit, any Application or any Eurodollar Loan made by it, or change
         the basis of taxation of payments to such Lender in respect thereof
         (except for Non-Excluded Taxes covered by subsection 2.15 and changes
         in the rate of net income taxes (including branch profits taxes and
         minimum taxes) or franchise taxes (imposed in lieu of net income
         taxes) of such Lender);

                      (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the Eurodollar Rate
         hereunder; or

                    (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting
into, continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender
upon written demand such additional amount or amounts as will compensate such
Lender for such increased cost or reduced amount receivable; provided that
before making any such demand, each Lender agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions and
so long as such efforts would not be disadvantageous to it, in its reasonable
discretion, in any legal, economic or regulatory manner) to designate a
different Eurodollar lending office if the making of such designation would
allow the Lender or its Eurodollar lending office to continue to perform its
obligations to make Eurodollar Loans or to continue to fund or maintain
Eurodollar Loans and avoid the need for, or reduce the amount of, such
increased cost. If any Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the Borrower, through the
Administrative Agent, of the event by reason of which it has become so
entitled. If the Borrower so



                                       34

<PAGE>





notifies the Administrative Agent within five Business Days after any Lender
notifies the Borrower of any increased cost pursuant to the foregoing
provisions of this Section, the Borrower may convert all Eurodollar Loans of
such Lender then outstanding into Base Rate Loans in accordance with the terms
hereof. Each Lender shall notify the Borrower within 120 days after it becomes
aware of the imposition of such costs; provided that if such Lender fails to so
notify the Borrower within such 120-day period, such Lender shall not be
entitled to claim any additional amounts pursuant to this subsection for any
period ending on a date which is prior to 120 days before such notification.

                 (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such adoption, change or compliance (taking into consideration such
Lender's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a prompt written request therefor, the Borrower shall promptly pay to
such Lender such additional amount or amounts as will compensate such Lender
for such reduction. Each Lender shall notify the Borrower within 120 days after
it becomes aware of the imposition of such additional amount or amounts;
provided that if such Lender fails to so notify the Borrower within such
120-day period, such Lender shall not be entitled to claim any additional
amount or amounts pursuant to this subsection for any period ending on a date
which is prior to 120 days before such notification.

                 (c) If any Lender becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Borrower
(with a copy to the Administrative Agent) of the event by reason of which it
has become so entitled. A certificate as to any additional amounts payable
pursuant to this subsection, showing the calculation thereof in reasonable
detail, submitted by such Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
agreements in this subsection shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                 2.15 Taxes. (a) Except as provided in this subsection 2.15,
all payments made by the Borrower under this Agreement and any Notes shall be
made free and clear of, and without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority
("Taxes"), excluding Taxes on net income (including, without limitation, branch
profits taxes and minimum taxes) and franchise taxes (imposed in lieu of net
income taxes) imposed on any Agent or any Lender as a result of a present or
former connection between any Agent or such Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely
from such Agent or such Lender having



                                       35

<PAGE>





executed, delivered or performed its obligations or received a payment under,
or enforced, this Agreement or any Note). If any such non-excluded taxes,
levies, imposts, duties, charges, fees deductions or withholdings
("Non-Excluded Taxes") are required to be withheld from any amounts payable to
any Agent or any Lender hereunder or under any Note, the amounts so payable to
such Agent or such Lender shall be increased to the extent necessary to yield
to such Agent or such Lender (after payment of all Non-Excluded Taxes) interest
or any such other amounts payable hereunder at the rates or in the amounts
specified in this Agreement, provided, however, that the Borrower shall not be
required to increase any such amounts payable to any Lender that is not
organized under the laws of the United States of America or a state thereof
with respect to any Taxes that are imposed on amounts payable to such Lender at
the time such Lender becomes a party to this Agreement or that are attributable
to such Lender's failure to comply with the requirements of paragraph (b) of
this subsection. Whenever any Non-Excluded Taxes are payable by the Borrower,
as promptly as possible thereafter, the Borrower shall send to the relevant
Agent for its own account or for the account of such Lender, as the case may
be, a certified copy of an original official receipt, if any, received by the
Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded
Taxes when due to the appropriate taxing authority or fails to remit to the
relevant Agent the required receipts or other required documentary evidence,
the Borrower shall indemnify the Agents and the Lenders for any incremental
taxes, interest or penalties that may become payable by any Agent or any Lender
as a result of any such failure. The agreements in this subsection shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

                 (b) Each Lender, Assignee and Participant that is not a
citizen or resident of the United States of America, a corporation, partnership
created or organized in or under the laws of the United States of America, any
estate that is subject to U.S. federal income taxation regardless of the source
of its income or any trust which is subject to the supervision of a court
within the United States and the control of a United States fiduciary as
described in Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall
deliver to the Borrower and the Administrative Agent, and if applicable, the
assigning Lender (or, in the case of a Participant, to the Lender from which
the related participation shall have been purchased) on or before the date on
which it becomes a party to this Agreement (or, in the case of a Participant,
on or before the date on which such Participant purchases the related
participation) either:

                 (A) two duly completed and signed copies of either Internal
         Revenue Service Form 1001 (relating to such Non-U.S. Lender and
         entitling it to a complete exemption from withholding of U.S. Taxes on
         all amounts to be received by such Non-U.S. Lender pursuant to this
         Agreement and the other Credit Documents) or Form 4224 (relating to
         all amounts to be received by such Non-U.S. Lender pursuant to this
         Agreement and the other Credit Documents), or successor and related
         applicable forms, as the case may be; or

                 (B) in the case of a Non-U.S. Lender that is not a "bank"
         within the meaning of Section 881(c)(3)(A) of the Code and that does
         not comply with the requirements of clause (A) hereof, (x) a statement
         in the form of Exhibit F (or such other form of statement as shall be
         reasonably requested by the Borrower from time to time) to the effect
         that such Non-U.S. Lender is eligible for a complete



                                       36

<PAGE>





         exemption from withholding of U.S. Taxes under Code Section 871(h) or
         881(c), and (y) two duly completed and signed copies of Internal
         Revenue Service Form W-8 or successor and related applicable form (it
         being understood and agreed that no Participant and, without the prior
         written consent of the Borrower described in clause (B) of the proviso
         to the first sentence of subsection 10.6(c), no Assignee shall be
         entitled to deliver any forms or statements pursuant to this clause
         (B), but rather shall be required to deliver forms pursuant to clause
         (A) of this subsection 2.15(b)).

Further, each Non-U.S. Lender agrees (i) to deliver to the Borrower and the
Administrative Agent, and if applicable, the assigning Lender (or, in the case
of a Participant, to the Lender from which the related participation shall have
been purchased) two further duly completed and signed copies of such Forms 1001
or 4224, as the case may be, or successor and related applicable forms, on or
before the date that any such form expires or becomes obsolete and promptly
after the occurrence of any event requiring a change from the most recent
form(s) previously delivered by it to the Borrower (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) in accordance with applicable U.S. laws and regulations and (ii) in
the case of a Non-U.S. Lender that delivers a statement in the form of Exhibit
F (or such other form of statement as shall have been requested by the
Borrower), to deliver to the Borrower and the Administrative Agent, and if
applicable, the assigning Lender, such statement on an annual basis on the
anniversary of the date on which such Non-U.S. Lender became a party to this
Agreement and to deliver promptly to the Borrower and the Administrative Agent,
and if applicable, the assigning Lender, such additional statements and forms
as shall be reasonably requested by the Borrower from time to time unless, in
any such case, any change in law or regulation has occurred subsequent to the
date such Lender became a party to this Agreement (or in the case of a
Participant, the date on which such Participant purchased the related
participation) which renders all such forms inapplicable or which would prevent
such Lender (or Participant) from properly completing and executing any such
form with respect to it and such Lender promptly notifies the Borrower and the
Administrative Agent (or, in the case of a Participant, the Lender from which
the related participation shall have been purchased) if it is no longer able to
deliver, or if it is required to withdraw or cancel, any form or statement
previously delivered by it pursuant to this subsection 2.15(b). Each Non-U.S.
Lender agrees to indemnify and hold harmless the Borrower from and against any
taxes, penalties, interest or other costs or losses (including, without
limitation, reasonable attorneys' fees and expenses) incurred or payable by the
Borrower as a result of the failure of the Borrower to comply with its
obligations to deduct or withhold any U.S. Taxes from any payments made
pursuant to this Agreement to such Non-U.S. Lender or the Administrative Agent
which failure resulted from the Borrower's reliance on any form, statement,
certificate or other information provided to it by such Non-U.S. Lender
pursuant to clause (B) or clause (ii) of this subsection 2.15(b). The Borrower
hereby agrees that for so long as a Non-U.S. Lender complies with this
subsection 2.15(b), the Borrower shall not withhold any amounts from any
payments made pursuant to this Agreement to such Non-U.S. Lender, unless the
Borrower reasonably determines that it is required by law to withhold or deduct
any amounts from any payments made to such Non-U.S. Lender pursuant to this
Agreement. A Non-U.S. Lender shall not be required to deliver any form or
statement pursuant to the immediately preceding sentences in this subsection
2.15(b) that such Non-U.S. Lender is not legally able to deliver (it being
understood and agreed that the Borrower shall withhold or deduct such amounts
from any



                                       37

<PAGE>





payments made to such Non-U.S. Lender that the Borrower reasonably determines
are required by law and that payments resulting from a failure to comply with
this paragraph (b) shall not be subject to payment or indemnity by the Borrower
pursuant to subsection 2.15(a)). If any Credit Party other than the Borrower
makes any payment to any Non-U.S. Lender under any Credit Document, the
foregoing provisions of this subsection 2.15 shall apply to such Non-U.S.
Lender and such Credit Party as if such Credit Party were the Borrower (but a
Non-U.S. Lender shall not be required to provide any form or make any statement
to any such Credit Party unless such Non-U.S. Lender has received a request to
do so from such Credit Party and has a reasonable time to comply with such
request).

                 (c) If a Lender shall become aware that it is entitled to
receive a refund (whether by way of a direct payment or by offset) in respect
of a Non-Excluded Tax paid by the Borrower, which refund, in the good faith
judgment of such Lender, is allocable to such payment made pursuant to this
Section, it shall promptly notify the Borrower of the availability of such
refund and shall, within 30 days after the receipt of a request from the
Borrower, apply for such refund at the Borrower's sole expense. If any Lender
receives such refund (as described in the preceding sentence), it shall repay
the amount of such refund (together with any interest received thereon) to the
Borrower if all the payments due under this Section has been paid in full.

                 2.16 Indemnity. The Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any loss or expense which such Lender may
sustain or incur as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment of Eurodollar
Loans on a day which is not the last day of an Interest Period with respect
thereto (but excluding loss of margin). Such indemnification under this
subsection 2.16 may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans
provided for herein (but excluding loss of margin) over (ii) the amount of
interest (as reasonably determined by such Lender) which would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank eurodollar market. Each Lender
claiming any payment pursuant to this subsection 2.16 shall do so by giving
notice thereof to the Borrower and the Administrative Agent (showing
calculation of the amount claimed in reasonable detail) within 60 Business Days
after a failure to borrow, convert or continue Eurodollar Loans, or to prepay,
after notice or after a prepayment of Eurodollar Loans on a day which is not
the last day of an Interest Period therefor. This covenant shall survive the
termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder.

                 2.17 Replacement of Lenders. If at any time (a) the Borrower
becomes obligated to pay additional amounts described in subsections 2.13, 2.14
or 2.15 as a result of any condition described in such



                                       38

<PAGE>





subsections, or any Lender ceases to make Eurodollar Loans pursuant to
subsection 2.13, (b) any Lender becomes insolvent and its assets become subject
to a receiver, liquidator, trustee, custodian or other Person having similar
powers or (c) any Lender becomes a "Nonconsenting Lender" (hereinafter
defined), then the Borrower may, on ten Business Days' prior written notice to
the Administrative Agent and such Lender, replace such Lender by causing such
Lender to (and such Lender shall) assign pursuant to subsection 10.6 all of its
rights and obligations under this Agreement to a Lender or other entity
selected by the Borrower and acceptable to the Administrative Agent for a
purchase price equal to the outstanding principal amount of such Lender's Loans
and all accrued interest and fees and other amounts payable hereunder
(including amounts payable under subsection 2.16 as though such Loans were
being paid instead of being purchased); provided that (i) the Borrower shall
have no right to replace the Administrative Agent, (ii) neither the
Administrative Agent nor any Lender shall have any obligation to the Borrower
to find a replacement Lender or other such entity, (iii) in the event of a
replacement of a Nonconsenting Lender or a Lender to which the Borrower becomes
obligated to pay additional amounts pursuant to this subsection 2.17, in order
for the Borrower to be entitled to replace such a Lender, such replacement must
take place no later than 180 days after (A) the date the Nonconsenting Lender
shall have notified the Borrower and the Administrative Agent of its failure to
agree to any requested consent, waiver or amendment or (B) the Lender shall
have demanded payment of additional amounts under one of the subsections
described in this subsection 2.17, as the case may be, and (iv) in no event
shall the Lender hereby replaced be required to pay or surrender to such
replacement Lender or other entity any of the fees received by such Lender
hereby replaced pursuant to this Agreement. In the case of a replacement of a
Lender to which the Borrower becomes obligated to pay additional amounts
pursuant to this subsection 2.17, the Borrower shall pay such additional
amounts to such Lender prior to such Lender being replaced and the payment of
such additional amounts shall be a condition to the replacement of such Lender.
In the event that (x) the Borrower or the Administrative Agent has requested
the Lenders to consent to a departure or waiver of any provisions of the Credit
Documents or to agree to any amendment thereto, (y) the consent, waiver or
amendment in question requires the agreement of all Lenders in accordance with
the terms of subsection 10.1 and (z) the Required Lenders have agreed to such
consent, waiver or amendment, then any Lender who does not agree to such
consent, waiver or amendment shall be deemed a "Nonconsenting Lender."

                 2.18 Certain Fees. The Company agrees to pay to the
Administrative Agent, for its own account, a non-refundable administration fee
in an amount previously agreed to with the Administrative Agent, payable in
advance on the Closing Date and annually in advance on each anniversary thereof
prior to the earlier of (x) the Final Maturity Date and (y) the payment in full
of all Loans and all other amounts owing under this Agreement.

                 2.19 Certain Rules Relating to the Payment of Additional
Amounts. (a) Upon the request, and at the expense, of the Borrower, each Lender
to which the Borrower is required to pay any additional amount pursuant to
Section 2.14 or 2.15 shall reasonably afford the Borrower the opportunity to
contest, and reasonably cooperate with the Borrower in contesting, the
imposition of any Non-Excluded taxes giving rise to such payment; provided that
(i) such Lender shall not be required to afford the Borrower the opportunity to
so contest unless the Borrower shall have confirmed in writing to such Lender
its obligation to pay such amounts



                                       39

<PAGE>





pursuant to this Agreement and (ii) the Borrower shall reimburse such Lender
for its reasonable attorneys' and accountants' fees and disbursements incurred
in so cooperating with the Borrower in contesting the imposition of such
Non-Excluded Taxes.

                 (b) Each Lender agrees that if it makes any demand for payment
under subsection 2.14 or 2.15(a), or if any adoption or change of the type
described in subsection 2.13 shall occur with respect to it, it will use
reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions and so long as such efforts would not be
disadvantageous to it, as determined in its reasonable discretion) to designate
a different lending office if the making of such a designation would allow the
Lender to continue to make and maintain Eurodollar Loans and would reduce or
obviate the need for the Borrower to make payments under subsection 2.14 or
2.15(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 2.13.


                         SECTION 3.  LETTERS OF CREDIT

                 3.1 L/C Commitment. (a) Subject to the terms and conditions
hereof, the Issuing Lender, in reliance on the agreements of the Revolving
Credit Lenders set forth in subsection 3.4(a), agrees to issue letters of
credit ("Letters of Credit") for the account of the Borrower on any Business
Day during the Commitment Period in such form as may be approved from time to
time by the Issuing Lender; provided that the Issuing Lender shall have no
obligation to issue any Letter of Credit if, after giving effect to such
issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the
Available Commitment with respect to Revolving Credit Loans of all Revolving
Credit Lenders less the aggregate principal amount of the Swing Line Loans then
outstanding would be less than zero.

                 (b) Each Letter of Credit shall (i) be denominated in Dollars,
(ii) be a standby letter of credit issued to support obligations of the
Borrower or any of its Subsidiaries, contingent or otherwise and (iii) expire
no later than the earlier of (x) the date that is 12 months after the date of
its issuance and (y) the fifth Business Day prior to the Revolving Loan
Termination Date; provided that any Letter of Credit with an expiration date
occurring up to twelve months after such Letter of Credit's date of issuance
may be automatically renewable for subsequent 12-month periods (but in no event
later than the fifth Business Day prior to the Revolving Loan Termination
Date).

                 (c) Each Letter of Credit shall be subject to the Uniform
Customs and, to the extent not inconsistent therewith, the laws of the State of
New York.

                 (d) The Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would conflict with, or
cause the Issuing Lender or any L/C Participant to exceed any limits imposed
by, any applicable Requirement of Law or any policies of the Issuing Lender.

                 3.2 Procedure for Issuance of Letters of Credit. The Borrower
may from time to time request that the Issuing Lender issue a Letter of Credit
at any time prior to the fifth Business Day prior to the Revolving Loan
Termination Date by delivering to the Issuing Lender with a copy to the



                                       40

<PAGE>





Administrative Agent at its address for notices specified herein an Application
therefor, completed to the satisfaction of the Issuing Lender, and such other
certificates, documents and other papers and information as the Issuing Lender
may reasonably request. Upon receipt of any Application, the Issuing Lender
will process such Application and the certificates, documents and other papers
and information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall the Issuing Lender be required to issue any
Letter of Credit earlier than three Business Days after its receipt of the
Application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of
such Letter of Credit to the Borrower and the Administrative Agent (with copies
for each Lender) promptly following the issuance thereof.

                 3.3 Fees, Commissions and Other Charges. (a) The Borrower
shall pay to the Administrative Agent, for the account of the Issuing Lender
and the L/C Participants, a letter of credit fee with respect to each Letter of
Credit, computed for the period from and including the date of issuance of such
Letter of Credit to the expiration date of such Letter of Credit at a rate per
annum equal to the Applicable Margin then in effect for Eurodollar Loans, of
the aggregate face amount of Letters of Credit outstanding, payable in arrears
on each L/C Fee Payment Date and on the Revolving Loan Termination Date. Such
fee shall be payable to the Administrative Agent to be shared ratably among the
Revolving Credit Lenders in accordance with their respective Commitment
Percentages with respect to Revolving Credit Loans. In addition, the Borrower
shall pay to the Administrative Agent, for the sole account of the Issuing
Lender, a fee equal to 0.1250% per annum of the aggregate face amount of
outstanding Letters of Credit payable quarterly in arrears on each L/C Fee
Payment Date and on the Revolving Loan Termination Date.

                 (b) In addition to the foregoing fees and commissions, the
Borrower shall pay or reimburse the Issuing Lender for such normal and
customary costs and expenses as are incurred or charged by the Issuing Lender
in issuing, effecting payment under, amending or otherwise administering any
Letter of Credit.

                 (c) The Administrative Agent shall, promptly following its
receipt thereof, distribute to the Issuing Lender and the L/C Participants all
fees and commissions received by the Administrative Agent for their respective
accounts pursuant to this subsection.

                 3.4 L/C Participation. (a) The Issuing Lender irrevocably
agrees to sell and hereby sells to each L/C Participant, and, to induce the
Issuing Lender to issue Letters of Credit hereunder, each L/C Participant
irrevocably agrees to accept and purchase and hereby accepts and purchases from
the Issuing Lender, on the terms and conditions hereinafter stated, for such
L/C Participant's own account and risk an undivided interest equal to such L/C
Participant's Commitment Percentage with respect to Revolving Credit Loans from
time to time in effect in the Issuing Lender's obligations and rights under
each Letter of Credit issued hereunder and the amount of each draft paid by the
Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably
agrees with the Issuing Lender that, if a draft is paid under any Letter of
Credit for which the Issuing Lender is not



                                       41

<PAGE>





reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at
the Issuing Lender's address for notices specified herein an amount equal to
such L/C Participant's then Commitment Percentage with respect to Revolving
Credit Loans of the amount of such draft, or any part thereof, which is not so
reimbursed; provided that, if such demand is made prior to 11:00 A.M., New York
City time, on a Business Day, such L/C Participant shall make such payment to
the Issuing Lender prior to the end of such Business Day and otherwise such L/C
Participant shall make such payment on the next succeeding Business Day.

                 (b) If any amount required to be paid by any L/C Participant
to the Issuing Lender pursuant to subsection 3.4(a) in respect of any
unreimbursed portion of any payment made by the Issuing Lender under any Letter
of Credit is paid to the Issuing Lender within three Business Days after the
date such payment is due, such L/C Participant shall pay to the Issuing Lender
on demand an amount equal to the product of (i) such amount, times (ii) the
daily average Federal funds rate, as quoted by the Issuing Lender, during the
period from and including the date such payment is required to the date on
which such payment is immediately available to the Issuing Lender, times (iii)
a fraction the numerator of which is the number of days that elapse during such
period and the denominator of which is 360. If any such amount required to be
paid by any L/C Participant pursuant to subsection 3.4(a) is not in fact made
available to the Issuing Lender by such L/C Participant within three Business
Days after the date such payment is due, the Issuing Lender shall be entitled
to recover from such L/C Participant, on demand, such amount with interest
thereon calculated from such due date at the rate per annum applicable to Base
Rate Loans hereunder. A certificate of the Issuing Lender submitted to any L/C
Participant with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.

                 (c) Whenever, at any time after the Issuing Lender has made
payment under any Letter of Credit and has received from any L/C Participant
its pro rata share of such payment in accordance with subsection 3.4(a), the
Issuing Lender receives any payment related to such Letter of Credit (whether
directly from the Borrower or otherwise, including proceeds of collateral
applied thereto by the Issuing Lender), or any payment of interest on account
thereof, the Issuing Lender will, if such payment is received prior to 11:00
A.M., New York City time, on a Business Day, distribute to such L/C Participant
its pro rata share thereof prior to the end of such Business Day and otherwise
the Issuing Lender will distribute such payment on the next succeeding Business
Day; provided, however, that in the event that any such payment received by the
Issuing Lender and distributed to the L/C Participants shall be required to be
returned by the Issuing Lender, each such L/C Participant shall return to the
Issuing Lender the portion thereof previously distributed by the Issuing Lender
to it.

                 3.5 Reimbursement Obligation of the Borrower. (a) The Borrower
agrees to reimburse the Issuing Lender on the same Business Day on which the
Issuing Lender notifies the Borrower of the date and amount of a draft
presented under any Letter of Credit and paid by the Issuing Lender provided
such notice is received by 1:00 P.M., New York City time, on such Business Day,
and the next Business Day if such notice is received after such time. The
Issuing Lender shall provide notice to the Borrower on each Business Day on
which a draft is presented and paid by the Issuing Lender indicating the amount
of (i) such draft so paid and (ii) any taxes, fees,



                                       42

<PAGE>





charges or other costs or expenses incurred by the Issuing Lender in connection
with such payment. Each such payment shall be made to the Issuing Lender at its
address for notices specified herein in lawful money of the United States of
America and in immediately available funds.

                 (b) Interest shall be payable on any and all amounts remaining
unpaid by the Borrower under this subsection from the date a draft presented
under any Letter of Credit is paid by the Issuing Lender until payment in full
(i) at the rate which would be payable on any Loans that are Base Rate Loans at
such time until such payment is required to be made pursuant to subsection
3.5(a), and (ii) thereafter, at the rate which would be payable on any Loans
that are Base Rate Loans at such time which were then overdue.

                 3.6 Obligations Absolute. (a) The Borrower's obligations under
subsection 3.5(a) shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Borrower may have or have had against the Issuing Lender, any
L/C Participant or any beneficiary of a Letter of Credit.

                 (b) The Borrower also agrees with the Issuing Lender that the
Issuing Lender shall not be responsible for, and the Borrower's Reimbursement
Obligations under subsection 3.5(a) shall not be affected by, among other
things, (i) the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged (unless the Issuing Lender has knowledge of such
invalidity, fraud or forgery), or (ii) any dispute between or among the
Borrower and any beneficiary of any Letter of Credit or any other party to
which such Letter of Credit may be transferred or (iii) any claims whatsoever
of the Borrower against any beneficiary of such Letter of Credit or any such
transferee.

                 (c) Neither the Issuing Lender nor any L/C Participant shall
be liable for any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit, except for errors or omissions caused by
the Issuing Lender's gross negligence or willful misconduct.

                 (d) The Borrower agrees that any action taken or omitted by
the Issuing Lender under or in connection with any Letter of Credit or the
related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards of care specified in
the Uniform Commercial Code of the State of New York, shall be binding on the
Borrower and shall not result in any liability of the Issuing Lender or any L/C
Participant to the Borrower.

                 3.7 Letter of Credit Payments. If any draft shall be presented
for payment under any Letter of Credit, the Issuing Lender shall promptly
notify the Borrower and the Administrative Agent of the date and amount
thereof. If any draft shall be presented for payment under any Letter of
Credit, the responsibility of the Issuing Lender to the Borrower in connection
with such draft shall, in addition to any payment obligation expressly provided
for in such Letter of Credit, be limited to determining that the documents
(including each draft) delivered under such Letter of Credit in connection with
such presentment appear on their face to be in conformity with such Letter of
Credit.



                                       43

                 3.8 Application. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall govern and control.

                  SECTION 4.  REPRESENTATIONS AND WARRANTIES

                 To induce the Agents, the Issuing Lender, the Swing Line
Lender and the Lenders to enter into this Agreement and to make the Loans and
issue or participate in the Letters of Credit, the Borrower hereby represents
and warrants to the Agents, the Issuing Lender, the Swing Line Lender and each
Lender that:

                 4.1 Financial Condition. (a) The combined balance sheets of
the Lockheed Martin Predecessor Businesses as at December 31, 1996 and December
31, 1995 and the related combined statements of operations and changes in
invested equity and cash flows for each of the three years in the period ended
December 31, 1996, audited by Coopers & Lybrand L.L.P., copies of which have
heretofore been furnished to each Lender, present fairly, in all material
respects, in accordance with GAAP the combined financial condition of the
Lockheed Martin Predecessor Businesses as of such dates, and the combined
results of their operations and changes in invested equity and cash flows for
each of the years in the period ended December 31, 1996. All such financial
statements have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such auditors and as
disclosed therein). To the best of the Borrower's knowledge, none of the
Lockheed Martin Predecessor Businesses had, at the date of each balance sheet
referred to above, any material Guarantee Obligation, contingent liability or
liability for taxes, or any long-term lease or unusual forward or long-term
commitment, including, without limitation, any material interest rate or
foreign currency swap or exchange transaction, which is not reflected in the
foregoing statements or in the notes thereto or expressly permitted to be
incurred hereunder. To the best of the Borrower's knowledge, during the period
from December 31, 1996 to and including the date hereof there has been no sale,
transfer or other disposition by the Lockheed Martin Predecessor Businesses of
any material part of its business or property (except as disclosed in the
Transaction Documents) other than pursuant to the Asset Contribution and no
purchase or other acquisition of any business or property (including any
capital stock of any other Person) material in relation to the consolidated
financial condition of the Lockheed Martin Predecessor Businesses at December
31, 1996.

                 (b) The combined statements of operations and cash flows for
the three months ended March 31, 1996 and the years ended December 31, 1995 and
1994 of the Loral Acquired Businesses, audited by Coopers & Lybrand L.L.P.,
copies of which have heretofore been furnished to each Lender, present fairly,
in all material respects, in accordance with GAAP the combined results of
operations and cash flows of the Loral Acquired Businesses for the three months
ended March 31, 1996, and the years ended December 31, 1995 and 1994. All such
financial statements have been prepared in accordance with GAAP applied
consistently throughout the periods involved (except as approved by such
accountants and as disclosed therein). To the best of the Borrower's knowledge,
during the period from December 31, 1996 to and including the date hereof,
there has been no sale, transfer or other disposition by any of the Loral
Acquired Businesses of any material part of its business or property (except as
disclosed in the Transaction Documents) other than pursuant to the Asset
Contribution and no purchase or other acquisition of any business or property
(including any capital stock of any



                                       44

<PAGE>





other Person) material in relation to the consolidated financial condition of
Loral Acquired Businesses at December 31, 1996.

                 (c) The unaudited pro forma condensed consolidated financial
statements of the Borrower, as of December 31, 1996 and for the year then
ended, certified by a Responsible Officer (the "Pro Forma Financial
Statements"), copies of which have been furnished to each Lender, comprise the
unaudited combined financial statements of (x) the Lockheed Martin Predecessor
Businesses as of December 31, 1996 and for the year then ended and (y) the
Loral Acquired Businesses for the three months ended March 31, 1996, adjusted
to give effect (as if such events had occurred on such dates) to the Asset
Contribution and each of the other transactions contemplated by the Transaction
Documents. The Pro Forma Financial Statements have been prepared based on good
faith assumptions in accordance with Regulation S-X under the Securities
Exchange Act of 1934, as amended, and based on the best information available
to the Borrower, as of the date of delivery thereof, and reflect on a pro forma
basis the financial position and results of operations of the Borrower and its
Subsidiaries, as of December 31, 1996, and for the year then ended.

                 4.2 No Change. Since December 31, 1996 there has been no
development, event or circumstance which has had or could reasonably be
expected to have a Material Adverse Effect.

                 4.3 Corporate Existence; Compliance with Law. Each of
Holdings, the Borrower and its Subsidiaries (a) is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, (b) has the corporate power and authority, and the legal right,
to own and operate its property, to lease the property it operates as lessee
and to conduct the business in which it is currently engaged, (c) is, or will
be on or before the date set forth in subsection 6.12, duly qualified as a
foreign corporation and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of property or the conduct of its
business requires such qualification, except to the extent that the failure to
so qualify could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect and (d) is in compliance with all Requirements of Law
except to the extent that the failure to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

                 4.4 Corporate Power; Authorization; Enforceable Obligations.
Each of Holdings, the Borrower and its Subsidiaries has the corporate power and
authority, and the legal right, to make, deliver and perform the Credit
Documents to which it is a party and, in the case of the Borrower, to borrow
hereunder and has taken all necessary corporate action to authorize the
borrowings on the terms and conditions of this Agreement and to authorize the
execution, delivery and performance of such Credit Documents and Transaction
Documents. No consent or authorization of, filing with, notice to or other act
by or in respect of, any Governmental Authority or any other Person is required
in connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of the Credit Documents and Transaction
Documents to which the Borrower and each other Credit Party is a party, except
those referred to in subsections 4.17 and 6.13 and those set forth on Schedule
4.4. This Agreement has been, and each other Credit Document and Transaction
Document will be, duly executed and delivered on behalf of the Borrower and
each other Credit Party. This Agreement constitutes, and each other Credit
Document and Transaction Document to which it is a party when executed and
delivered will constitute,



                                       45

<PAGE>





a legal, valid and binding obligation of each Credit Party thereto enforceable
against each such Credit Party, as the case may be, in accordance with its
terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered
in a proceeding in equity or at law) and an implied covenant of good faith and
fair dealing.

                 4.5 No Legal Bar. Except as set forth on Schedule 4.5 or as
could not reasonably be expected to, individually or in the aggregate, have a
Material Adverse Effect, the execution, delivery and performance of each Credit
Document, the borrowing and use of the proceeds of the Loans and the
consummation of the transactions contemplated by the Credit Documents and the
Transaction Documents: (a) will not violate any Requirement of Law or any
Contractual Obligation applicable to or binding upon Holdings, the Borrower or
any Subsidiary of the Borrower or any of their respective properties or assets
and (b) will not result in the creation or imposition of any Lien on any of its
properties or assets pursuant to any Requirement of Law applicable to it or any
of its Contractual Obligations, except for the Liens arising under the Security
Documents.

                 4.6 No Material Litigation. Except as set forth on Schedule
4.6, no litigation by, investigation by, or proceeding of or before any
arbitrator or any Governmental Authority is pending or, to the knowledge of the
Borrower, overtly threatened by or against the Borrower or any of its
Subsidiaries or against any of its or their respective properties or revenues
(including after giving effect to the Asset Contribution and the other
transactions contemplated by the Transaction Documents) with respect to any
Credit Document or any of the transactions contemplated hereby or thereby or
which could reasonably be expected to have a Material Adverse Effect.

                 4.7 No Default. Neither Holdings, the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which could reasonably be expected to have a
Material Adverse Effect. No Default or Event of Default has occurred and is
continuing.

                 4.8 Ownership of Property; Liens. Each of Holdings, the
Borrower and its Subsidiaries (i) has good record and insurable title in fee
simple to all the real property listed on Schedule 4.8, (ii) has good record
and insurable title in fee simple to, or a valid leasehold interest in, all its
other material real property, (iii) has good title to, or a valid leasehold
interest in, all its other material property and (iv) none of such property in
clauses (i) through (iii) is or shall be subject to any Lien except as
permitted by subsection 7.3.

                 4.9 Intellectual Property. Holdings, the Borrower and each of
its Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not reasonably be expected to have a Material Adverse Effect (the
"Intellectual Property"). To the best of the Borrower's knowledge, and except
as set forth on Schedule 4.9, no claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim which could reasonably be
expected to have a Material Adverse



                                       46

<PAGE>





Effect. The use of such Intellectual Property by Holdings, the Borrower and its
Subsidiaries does not infringe on the rights of any Person, except for such
claims and infringements that, in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

                 4.10 Taxes. Except as set forth on Schedule 4.10, each of
Holdings, the Borrower and its Subsidiaries has filed or caused to be filed all
material tax returns which, to the knowledge of the Borrower, are required to
be filed and has paid all taxes shown to be due and payable on said returns or
on any assessments made against it or any of its property and all other
material taxes, fees or other charges imposed on it or any of its property by
any Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of Holdings, the Borrower or its Subsidiaries, as the case may be); no
tax Lien has been filed, and, to the knowledge of the Borrower, no claim is
being asserted, with respect to any such tax, fee or other charge.

                 4.11 Federal Regulations. No part of the proceeds of any Loans
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation G or
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect.

                 4.12 ERISA. The Borrower has provided to the Agents a true and
correct copy of all Agreements, arrangements and understandings relating to the
transfer of Plans from the Seller to the Borrower (the "Transfer Agreements").
The Transfer Agreements are in full force and effect and have not been waived
or modified without the consent of the Agents (which shall not be unreasonably
withheld) except to the extent any such waiver or modification, singly or in
the aggregate, could not be reasonably expected to have a Material Adverse
Effect. Except as could not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect, no Reportable Event has occurred
with respect to any Single Employer Plan, all contributions required to be made
with respect to a Plan have been timely made; none of the Borrower or any of
its Subsidiaries nor any Commonly Controlled Entity has incurred any material
liability to or on account of a Plan pursuant to Section 409, 502(i), 502(1),
515, 4062, 4063, 4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a)(29),
4971, 4975 or 4980 of the Code or expects to incur any liability (including any
indirect, contingent or secondary liability) under any of the foregoing
Sections with respect to any Plan; no termination or, or institution of
proceedings to terminate or appoint a trustee to administer, a Single Employer
Plan has occurred; and each Plan has complied in all material respects with the
applicable provisions of ERISA and the Code (except that with respect to any
Multiemployer Plan, such representation is deemed made only to the knowledge of
the Borrower). No "accumulated funding deficiency" (within the meaning of
Section 412 of the Code or Section 302 of ERISA), extension of any amortization
period (within the meaning of Section 412 of the Code) or Lien in favor of the
PBGC or a Plan has arisen or has occurred during the five-year period prior to
the date on which this representation is made or deemed made with respect to
any Single Employer Plan. As of the last annual valuation date prior to the
date on which this representation is made or deemed made, the fair market value
of the assets available for benefits under each Single Employer Plan did not
exceed the actuarial present value of all accumulated benefit obligations under
such Plan by more than $20,000,000, all



                                       47

<PAGE>




as determined in accordance with Statement of Financial Accounting Standards
No. 87. Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan for which there is
any outstanding liability, and neither the Borrower nor any Commonly Controlled
Entity would become subject to any liability under ERISA if the Borrower or any
such Commonly Controlled Entity were to withdraw completely from all
Multiemployer Plans as of the valuation date most closely preceding the date on
which this representation is made or deemed made in an amount which would be
reasonably likely to have a Material Adverse Effect. To the best knowledge of
the Borrower, no such Multiemployer Plan is in Reorganization or Insolvent.

                 4.13 Investment Company Act; Other Regulations. None of the
Borrower or any of its Subsidiaries is an "investment company," or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended. None of the Borrower or any of its
subsidiaries is not subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board of Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness.

                 4.14 Subsidiaries. After giving effect to the consummation of
the Transaction, the Subsidiaries of the Borrower and their respective
jurisdictions of incorporation shall be as set forth on Schedule 4.14.

                 4.15 Purpose of Loans. The proceeds of the Loans shall be used
by the Borrower (i) to finance a portion of the Transaction and related fees
and expenses in an aggregate amount not to exceed $185,000,000 and (ii) for
working capital purposes in the ordinary course of business of the Borrower and
its Subsidiaries.

                 4.16  Environmental Matters.

                 Except insofar as any exception to any of the following, or
any aggregation of such exceptions, is not reasonably likely to result in a
Material Adverse Effect:

                 (a) The facilities and properties owned, leased or operated
         Holdings, by the Borrower or any of its Subsidiaries (the
         "Properties") do not contain, and have not previously contained, any
         Materials of Environmental Concern in amounts or concentrations which
         (i) constitute or constituted a violation of, or (ii) could reasonably
         be expected to give rise to liability under, any applicable
         Environmental Law.

                 (b) None of Holdings, the Borrower nor any of its Subsidiaries
         has received any written notice of violation, alleged violation,
         non-compliance, liability or potential liability regarding
         environmental matters or compliance with Environmental Laws with
         regard to any of the Properties or the Business, nor does the Borrower
         have knowledge or reason to believe that any such notice will be
         received or is being threatened.

                 (c) Materials of Environmental Concern have not been
         transported or disposed of from the Properties in violation of, or in
         a manner or to a location which could reasonably be expected to give
         rise to liability under, any applicable Environmental Law, nor have
         any Materials of Environmental Concern been generated, treated,



                                       48

<PAGE>





         stored or disposed of at, on or under any of the Properties in
         violation of, or in a manner that could reasonably be expected to give
         rise to liability under, any applicable Environmental Law.

                 (d) No judicial proceeding or governmental or administrative
         action is pending or, to the knowledge of the Borrower, threatened,
         under any Environmental Law to which Holdings, the Borrower or any
         Subsidiary is or, to the knowledge of the Borrower, will be named as a
         party or with respect to the Properties or the Business, nor are there
         any consent decrees or other decrees, consent orders, administrative
         orders or other orders, or other administrative or judicial
         requirements outstanding under any Environmental Law with respect to
         the Properties or the Business.

                 (e) There has been no release or threat of release of
         Materials of Environmental Concern at or from the Properties, or
         arising from or related to the operations of Holdings, the Borrower or
         any Subsidiary in connection with the Properties or otherwise in
         connection with the Business, in violation of or in amounts or in a
         manner that could reasonably give rise to liability under any
         applicable Environmental Laws.

                 (f) The Properties and all operations at the Properties are in
         compliance, and have in the last 3 years been in compliance, in all
         material respects with all applicable Environmental Laws, and there is
         no contamination at, under or about the Properties or violation of any
         applicable Environmental Law with respect to the Properties or the
         business operated by Holdings, the Borrower or any of its Subsidiaries
         (the "Business") which could materially interfere with the continued
         operation of the Properties or materially impair the fair saleable
         value thereof.

                 (g) Holdings, the Borrower and its Subsidiaries hold and are
         in compliance with all Environmental Permits necessary for their
         operations.

                 4.17 Collateral Documents. (a) Upon execution and delivery
thereof by the parties thereto, each of the Borrower Pledge and Security
Agreement, the Subsidiary Pledge and Security Agreement and the Parent Pledge
and Security Agreement will be effective to create in favor of the
Administrative Agent, for the ratable benefit of the Lenders, a legal, valid
and enforceable security interest in the pledged stock described therein and,
when stock certificates representing or constituting the pledged stock
described therein are delivered to the Administrative Agent, such security
interest shall, subject to the existence of Permitted Liens, constitute a
perfected first lien on, and security interest in, all right, title and
interest of the pledgor party thereto in the pledged stock described therein.

                 (b) Upon execution and delivery thereof by the parties
thereto, each of the Borrower Pledge and Security Agreement, the Subsidiary
Pledge and Security Agreement and the Parent Pledge and Security Agreement will
be effective to create in favor of the Administrative Agent, for the ratable
benefit of the Lenders, a legal, valid and enforceable security interest in the
collateral described therein. Uniform Commercial Code financing statements have
been filed in each of the jurisdictions listed on Schedule 4.17, each such
Agreement has been filed in each of the government



                                       49

<PAGE>





offices listed on Schedule 4.17 or arrangements have been made for such filing
in such jurisdictions, and upon such filings, and upon the taking of possession
by the Administrative Agent of any such collateral the security interests in
which may be perfected only by possession, such security interests will,
subject to the existence of liens as permitted by the definition of Permitted
Liens, constitute perfected first priority liens on, and security interests in,
all right, title and interest of the debtor party thereto in the collateral
described therein, except, in the case of each of the Borrower Pledge and
Security Agreement, the Subsidiary Pledge and Security Agreement and the Parent
Pledge and Security Agreement, to the extent that a security interest cannot be
perfected therein by the filing of a financing statement or the taking of
possession under the Uniform Commercial Code of the relevant jurisdiction.

                 (c) Upon (a) execution and delivery of the Mortgages by the
parties thereto, (b) the recording of such Mortgages in the jurisdiction listed
on Schedule 4.17 and (c) the payment of any required mortgage recording taxes,
each of the Mortgages will be effective to create in favor of the
Administrative Agent, for the ratable benefit of the Lenders, a legal, valid
and enforceable lien on the real property described therein and such liens
will, as of the Closing Date, subject to the existence of liens as permitted by
clauses (a), (e), (f) and (g) of the definition of Permitted Liens, constitute
first priority liens on the real property described therein.

                 4.18 Accuracy and Completeness of Information. No fact is
known to Holdings, the Borrower or any of its Subsidiaries which has had or
could reasonably be expected to have a Material Adverse Effect, which has not
been disclosed to the Lenders by Holdings, the Borrower or its Subsidiaries in
writing prior to the date hereof. No document furnished or statement made in
writing to the Lenders by Holdings, the Borrower, any Subsidiary or any party
to any of the Transaction Documents in connection with the negotiation,
preparation or execution of this Agreement or any of the other Credit
Documents, taken as a whole, (including the Confidential Offering Memorandum
dated April 1997 relating to this facility but excluding all projections
(including industry forecasts and statistical data) and pro forma financial
statements (whether or not contained therein) which shall have been prepared in
good faith and based upon reasonable assumptions) contains any untrue statement
of a material fact or omits to state any such material fact necessary in order
to make the statements contained therein not misleading in the context in which
such statements are made. The Equity Documents constitute all of the agreements
relating to the Equity Investment and the Subordinated Debt Documents
constitute all of the agreements relating to the Subordinated Debt.

                 4.19 Solvency. On the Closing Date and after giving effect to
the Asset Contribution and the other transactions contemplated by the
Transaction Documents including borrowings hereunder on such date and the
incurrence of all other Indebtedness and Guarantee Obligations being incurred
on such date, the Borrower is "Solvent," in that (a) the property, at a fair
valuation, of Holdings and its Subsidiaries, individually and taken together as
a single entity, will exceed their debts, (b) the present fair salable value of
the assets of Holdings and its Subsidiaries, individually and taken together as
a single entity, is not less than the amount that will be required to pay their
probable liabilities as such debts become absolute and matured, and (c) the
Borrower does not intend to, and does not believe that Holdings and its
Subsidiaries, individually and taken together as a single



                                       50

<PAGE>





entity, will, incur debts or liabilities beyond the their ability to pay as
such debts and liabilities mature. For purposes of this subsection, "debt"
means "liability on a claim" and "claim" means any (i) right to payment,
whether or not such a right is reduced to judgment, liquidated, unliquidated,
fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable,
secured, or unsecured or (ii) right to an equitable remedy for breach of
performance if such breach gives rise to a right to payment, whether or not
such right to an equitable remedy is reduced to judgment, fixed, contingent,
matured, unmatured, disputed, undisputed, secured, or unsecured.

                 4.20 Labor Matters. There are no strikes pending or, to the
Borrower's knowledge, overtly threatened against Holdings, the Borrower or any
of its Subsidiaries which, individually or in the aggregate, could reasonably
be expected to have a Material Adverse Effect. The hours worked and payments
made to employees of Holdings, the Borrower and each of its Subsidiaries (and
their predecessors) have not been in violation of the Fair Labor Standards Act
or any other applicable Requirement of Law, except to the extent such
violations could not, or in the aggregate, be reasonably expected to have a
Material Adverse Effect.

                 4.21 Transaction Documents. To the best of the Borrower's
knowledge, the representations and warranties contained in the Transaction
Documents, taken as a whole, are true and correct in all material respects as
of the Closing Date. On the Closing Date, the Asset Contribution will have been
consummated in accordance with the Transaction Documents.


                       SECTION 5.  CONDITIONS PRECEDENT

                 5.1 Conditions to Initial Loans. The agreement of each Lender
to make the initial extension of credit requested to be made by it is subject
to the satisfaction, immediately prior to or concurrently with the making of
such extension of credit (including the making of any Loan or the issuance of
any Letter of Credit) on the Closing Date, of the following conditions
precedent:

                 (a) Credit Documents. The Administrative Agent shall have
         received (i) this Agreement, (ii) the Guarantees, (iii) the Mortgages
         and (iv) the Security Documents, in each case executed, duly
         acknowledged and delivered by duly authorized officers of each party
         thereto, with a counterpart or a conformed copy for each Lender.
         Notwithstanding the foregoing, no Foreign Subsidiary of Holdings or
         the Borrower shall be required to execute a Subsidiary Guarantee or
         Subsidiary Pledge and Security Agreement, and no more than 65% of the
         capital stock of or equity interests in any Foreign Subsidiary of the
         Borrower, Holdings or any of their Subsidiaries, or any other of their
         Subsidiaries if more than 65% of the assets of such Subsidiary are
         securities of foreign companies (such determination to be made on the
         basis of fair market value), shall be required to be pledged
         hereunder.

                 (b) Related Agreements. The Administrative Agent shall have
         received, with a copy for each Lender, true and correct copies,
         certified as to authenticity by the Borrower, of each of the
         Transaction Documents and such other documents or instruments as may
         be reasonably requested by the Administrative Agent, including,



                                       51

<PAGE>





         without limitation, a copy of any debt instrument, security agreement
         or other material contract to which the Borrower or any of its
         Subsidiaries may be a party (after giving effect to the Asset
         Contribution).

                 (c) Asset Contribution. The Asset Contribution shall have been
         consummated pursuant to the Transaction Agreement, and no material
         provision of the Transaction Agreement shall have been amended,
         supplemented, waived or otherwise modified without the prior written
         consent of the Agents. The Agents shall be reasonably satisfied with
         the aggregate amount of fees and expenses payable by the Borrower and
         its Subsidiaries in connection with the transactions contemplated
         hereby and by the Transaction Documents.

                 (d) Capitalization; Capital Structure (i) After giving effect
         to the Asset Contribution and the other transactions contemplated by
         the Transaction Documents, the Borrower shall have the capital
         structure set forth in the Pro Forma Financial Statements.

                      (ii) The Subordinated Debt Documents shall have been
         executed and delivered by the parties thereto (and shall be in form
         and substance reasonably satisfactory to the Agents), shall be in full
         force and effect and none of the provisions thereof shall have been
         amended, waived, supplemented or otherwise modified without the prior
         written consent of the Agents; and the Borrower shall have issued the
         Subordinated Debt in a principal amount, and received gross proceeds
         in the amount of $225,000,000.

                    (iii) The Equity Documents shall have been executed and
         delivered by the parties thereto (and shall be in form and substance
         reasonably satisfactory to the Agents), shall be in full force and
         effect and none of the provisions thereof shall have been amended,
         waived, supplemented or otherwise modified without the prior written
         consent of the Agents; and the Borrower shall have received at least
         $79,850,000 in net cash proceeds in accordance with the terms of the
         Equity Documents.

                 (e) Fees. The Agents, the Arranger and the Lenders shall have
         received all fees, expenses and other consideration required to be
         paid on or before the Closing Date.

                 (f) Lien Searches. The Administrative Agent shall have
         received the results of a search of Uniform Commercial Code, tax and
         judgment filings made with respect to each of the Borrower and its
         Subsidiaries (after giving effect to the Asset Contribution) and,
         without duplication, the Lockheed Martin Predecessor Businesses and
         the Loral Acquired Businesses in the jurisdictions set forth on
         Schedule 4.17 together with copies of financing statements disclosed
         by such searches, and such searches shall disclose no Liens on any
         assets encumbered by any Security Document, except for Liens permitted
         hereunder or, if unpermitted Liens are disclosed, the Administrative
         Agent shall have received satisfactory evidence of the release of such
         Liens.

                 (g) Consents, Authorizations and Filings, etc. Except for the
         financing statements contemplated by the Security Documents and



                                       52

<PAGE>




         the filing of the Security Documents and the Assignment Consent, all
         consents, authorizations and filings, if any, required in connection
         with the execution, delivery and performance by the Credit Parties,
         and the validity and enforceability against the Credit Parties, of the
         Credit Documents to which any of them is a party, shall have been
         obtained or made, and such consents, authorizations and filings shall
         be in full force and effect, except such consents, authorizations and
         filings, the failure to obtain which would not have a Material Adverse
         Effect.

                 (h) Insurance. The Lenders shall have received (i) a
         reasonably satisfactory schedule describing all insurance maintained
         by the Borrower and its Subsidiaries (after giving effect to the Asset
         Contribution) pursuant to subsection 6.5, and (ii) binders (or other

business; and keep all property useful and necessary in its business in good

of the Borrower or such Subsidiary, as the case may be, it is in its best
economic interest not to preserve and maintain such rights, privileges or
franchises, and (ii) such failure to preserve and maintain such privileges,
rights or franchises would not materially adversely affect the rights of the

and Requirements of Law except to the extent that failure to comply therewith
could not, in the aggregate, be reasonably expected to have a Material Adverse
Effect.

financially sound and reputable insurance companies insurance on all its
property in at least such amounts and against at least such risks (but

Subsidiaries to maintain, to the extent obtainable on commercially reasonable
terms, (i) property and casualty insurance on all real and personal property on

compensation shall be paid to the Borrower or the Subsidiary; provided that:
(A) the Borrower or the Subsidiary will use such proceeds, condemnation award
or other compensation to repair, restore or replace the assets which were the
subject of such claim within 6 months (or in the case of real property, 12
months) after receipt thereof (and a Responsible Officer shall deliver a
certificate specifying in reasonable detail such usage not later than the last
day of such relevant period), and (B) if, at the time of the receipt of such
proceeds, condemnation award or other compensation, an Event of Default has
occurred and is continuing, the aggregate amount of all such proceeds,
condemnation award or other compensation shall be paid to the Administrative
Agent and held as collateral for application in accordance with the Security
Documents; and provided further that, to the extent that any amount of such

the Administrative Agent and held as Collateral for application in accordance
with the Security Documents.

                 6.14 Maintenance of Collateral; Alterations. Refrain from
committing any waste on any Collateral, except in the ordinary course of its
business, or make any material change in the use of any Collateral, provided
that any Credit Party may sell or lease to any other Person all or any portion
of any item of Collateral that the Borrower has determined in good faith is not
used or useful in such Credit Party's operating business. Each Credit Party
granting a security interest in Collateral constituting real property
represents and warrants that, to the best of its knowledge: (a) such Collateral
is served by all utilities required or necessary for the current use thereof;
(b) all streets (or public rights-of-way) necessary to serve such Collateral
are completed and serviceable and have been dedicated and accepted as such by

(or rights-of-way); and (c) such Credit Party has access to such Collateral
from public roads (or rights-of-way), either directly or by insurable easements
(or rights-of-way), sufficient to allow such Credit Parties to conduct its
business at such Collateral in accordance with sound commercial and industrial
practices. The Credit Parties shall, at all times, maintain all non-possessory
collateral and all real estate collateral that is materially useful or
necessary in their respective businesses, in good operating order, condition
and repair, ordinary wear and tear and damage by fire and/or other casualty or
taking by condemnation excepted, and in accordance with all applicable laws,
rules and regulations, (including, without limitation, Environmental Laws) the
failure to comply with which would have a material adverse effect on the value
or usefulness of such Collateral, except where the necessity of compliance
therewith is contested in good faith by appropriate proceedings. Each Credit
Party shall do what is deemed commercially reasonable to maintain and preserve
the value of the Collateral.

         days from the entry thereof; or

                 (i) (i) Any of the Security Documents shall cease, for any
         reason, to be in full force and effect (unless released by the
         Administrative Agent at the direction of the requisite Lenders or as
         otherwise permitted under this Agreement or the other Credit
         Documents), or the Borrower or any other Credit Party which is a



                                       79

<PAGE>





         party to any of the Security Documents shall so assert or (ii) the
         Lien created by any of the Security Documents shall cease to be
         enforceable and of the same effect and priority purported to be
         created thereby (and, if such invalidity is such so as to be amenable
         to cure without materially disadvantaging the position of the
         Administrative Agent and the Lenders, as the case may be, as secured
         parties thereunder, the Credit Party shall have failed to cure such
         invalidity within 30 days after notice from the Administrative Agent);
         or

                 (j) the Guarantee Obligation of any Credit Party under the
         Credit Documents 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 Credit Party or any Person acting on behalf of
         any Credit Party, shall deny or disaffirm its obligations under such
         Guarantee Obligation;

                 (k) There shall have occurred a Change in Control; or

                 (l) either (i) the novation of any Government Contract
         existing on the date of this Agreement shall not be complete and
         effective prior to October 31, 1998 if such failures, individually or
         in the aggregate, could reasonably be expected to have a Material
         Adverse Effect, (ii) the consent to assignment of claims under any
         Government Contract (other than any Restricted Government Contract)
         existing on the date of this Agreement to the Administrative Agent on
         behalf of the Lenders shall not have been obtained prior to October
         31, 1998 if such failures, individually or in the aggregate, could
         reasonably be expected to have a Material Adverse Effect, or (iii) the
         Governmental Authority authorized to approve any such novation or
         consent to any such assignment requires a condition to the
         effectiveness to any such novation or consent which, if agreed to by
         the Company, could reasonably be expected to have a Material Adverse
         Effect;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) of this Section above with respect to
the Borrower, automatically the Commitments shall immediately terminate and the
Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement (including, without limitation, all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters
of Credit shall have presented the documents required thereunder) and the Notes
shall immediately become due and payable, and (B) if such event is any other
Event of Default, either or both of the following actions may be taken: (i)
with the consent of the Required Lenders, the Administrative Agent may, or upon
the request of the Required Lenders, the Administrative Agent shall, by notice
to the Borrower declare the Commitments to be terminated forthwith, whereupon
the Commitments shall immediately terminate; and (ii) with the consent of the
Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice of default to the
Borrower, declare the Loans hereunder (with accrued interest thereon) and all
other amounts owing under this Agreement (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) and the Notes to be due and payable forthwith, whereupon the same
shall immediately become due and payable.

         With respect to all Letters of Credit with respect to which
presentment for honor shall not have occurred at the time of an acceleration
pursuant to the preceding paragraph, the Borrower shall at such time deposit in
a cash collateral account opened by the Administrative Agent an amount equal to
the aggregate then undrawn and unexpired amount of such Letters of Credit. The
Borrower hereby grants to the Administrative Agent, for the benefit of the
Issuing Lender and the L/C Participants, a security interest in such cash
collateral to secure all obligations of the Borrower under this Agreement and
the other Credit Documents. Amounts held in such cash collateral account shall
be applied by the Administrative Agent to the payment of drafts drawn under
such Letters of Credit, and the unused portion thereof after all such Letters
of Credit shall have expired or been fully drawn upon, if any, shall be applied
to repay other obligations of the Borrower hereunder and under the Notes. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations
of the Borrower hereunder and under the Notes shall have been paid in full, the
balance, if any, in such cash collateral account shall be returned to the
Borrower. The Borrower shall execute and deliver to the Administrative Agent,
for the account of the Issuing Lender and the L/C Participants, such further
documents and instruments as the Administrative Agent may request to evidence
the creation and perfection of the within security interest in such cash
collateral account.

         EXCEPT AS EXPRESSLY PROVIDED ABOVE IN THIS SECTION, PRESENTMENT,
DEMAND, PROTEST AND ALL OTHER NOTICES OF ANY KIND ARE HEREBY EXPRESSLY
WAIVED.


                     SECTION 9.  THE AGENTS; THE ARRANGER

                 9.1 Appointment. Each Lender hereby irrevocably designates and
appoints each of the Agents as the agent of such Lender under this Agreement
and the other Credit Documents, and each such Lender irrevocably authorizes
each of the Agents, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Credit Documents and to exercise
such powers and perform such duties as are expressly delegated to such Agent by
the terms of this Agreement and the other Credit Documents, together with such
other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Agreement, none of the Agents shall
have any duties or responsibilities, except those expressly set forth herein,
or any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Credit Document or otherwise exist against any
of the Agents.

                 9.2 Delegation of Duties. The Agents may execute any of their
duties under this Agreement and the other Credit Documents by or through agents
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. None of the Agents shall be responsible for
the negligence or misconduct of any agents or attorneys in-fact selected by it
with reasonable care.

                 9.3 Exculpatory Provisions. Neither any of the Agents nor any
of their officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any



                                       81

<PAGE>





other Credit Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any officer thereof contained in this Agreement or any other Credit Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by such Agent under or in connection with, this Agreement
or any other Credit Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other
Credit Document or for any failure of the Borrower to perform its obligations
hereunder or thereunder. None of the Agents shall be under any obligation to
any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Credit Document, or to inspect the properties, books or records of the
Borrower.

                 9.4 Reliance by Agents. The Agents shall be entitled to rely,
and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to
be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Borrower), independent accountants and other
experts selected by such Agent. The Agents may deem and treat the payee of any
Note as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with such
Agent. Except as expressly provided in this Agreement, the Agents shall be
fully justified in failing or refusing to take any action under this Agreement
or any other Credit Document unless it shall first receive such advice or
concurrence of the Required Lenders as it deems appropriate or it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Agents shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Credit
Documents in accordance with a request of the Required Lenders, and such
request and any action taken or failure to act pursuant thereto shall be
binding upon all the Lenders and all future holders of the Loans.

                 9.5 Notice of Default. No Agent shall be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless such Agent has received notice from a Lender or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that any Agent
receives such a notice, such Agent shall give notice thereof to the Lenders.
Each Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders; provided that
unless and until such Agent shall have received such directions, such Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders.

                 9.6 Non-Reliance on Agents and Other Lenders. Each Lender
expressly acknowledges that neither any of the Agents nor any of their
officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by any of the
Agents hereafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any representation or warranty by any of the



                                       82

<PAGE>





Agents to any Lender. Each Lender represents to each of the Agents that it has,
independently and without reliance upon any of the Agents or any other Lender,
and based on such documents and information as it has deemed appropriate, made
its own appraisal of and investigation into the business, operations, property,
financial and other condition and credit worthiness of the Borrower and made
its own decision to make its Loans hereunder and enter into this Agreement.
Each Lender also represents that it will, independently and without reliance
upon any of the Agents or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Credit Documents, and to make such investigation
as it deems necessary to inform itself as to the business, operations,
property, financial and other condition and credit worthiness of the Borrower.
Except for notices, reports and other documents expressly required to be
furnished to the Lenders by any of the Agents hereunder (or copies of which
have been provided to the Administrative Agent pursuant to this Agreement),
none of the Agents shall have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or credit worthiness of
the Borrower which may come into the possession of such Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

                 9.7 Indemnification. The Lenders agree to indemnify each of
the Agents in their respective capacities as such (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Commitment Percentages with respect to
all Types of Loans in effect on the date on which indemnification is sought,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Loans) be imposed on, incurred by or asserted
against any of the Agents in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Credit Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any of the
Agents under or in connection with any of the foregoing provided that no Lender
shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting solely from such Agent's gross negligence
or willful misconduct. The agreements in this subsection shall survive the
payment of the Loans and all other amounts payable hereunder.

                 9.8 Agents, in Their Individual Capacities. The Agents and
their respective Affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Borrower as though the Agents
were not acting in such capacities hereunder and under the other Credit
Documents. With respect to the Loans made or renewed by it and any Note issued
to it and with respect to any Letter of Credit issued or participated in by it,
each Agent shall have the same rights and powers under this Agreement and the
other Credit Documents as any Lender and may exercise the same as though it
were not an Agent, and the terms "Lender" and "Lenders" shall include the
Agents in their individual capacities.

                 9.9  Successor Administrative Agent, Syndication Agents and
Documentation Agent.  The Administrative Agent, the Syndication Agent or the



                                       83

<PAGE>





Documentation Agent may resign as Administrative Agent, Syndication Agent or
Documentation Agent, as the case may be, upon 30 days' notice to the Lenders.
If the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Credit Documents or if Syndication Agent or the
Documentation Agent shall resign as Syndication Agent or Documentation Agent
under this Agreement and the other Credit Documents, then the Required Lenders
shall appoint from among the Lenders a successor agent for the Lenders, which
successor agent (provided that it shall have been approved by the Borrower,
which approval shall not be unreasonably withheld), shall succeed to the
rights, powers and duties of the Administrative Agent or a Syndication Agent or
the Documentation Agent, as the case may be, hereunder. Effective upon such
appointment and approval, the term "Administrative Agent" or a "Syndication
Agent" or "Documentation Agent," as the case may be, shall mean or include such
successor agent, and the former Administrative Agent's or Syndication Agent's
or Documentation Agent's, as the case may be, rights, powers and duties as
Administrative Agent or Syndication Agent or Documentation Agent, as the case
may be, shall be terminated, without any other or further act or deed on the
part of such former Administrative Agent or Syndication Agent or Documentation
Agent, as the case may be, or any of the parties to this Agreement or any
holders of the Loans. After any retiring Administrative Agent's or Syndication
Agent's or Documentation Agent's resignation as Administrative Agent or
Syndication Agent or Documentation Agent, as the case may be, the provisions of
this Section 9 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Administrative Agent or Syndication Agent or
Documentation Agent, as the case may be, under this Agreement and the other
Credit Documents.

                 9.10 The Arranger. Except as expressly set forth herein, the
Arranger, in its capacity as such, shall have no duties or responsibilities,
and shall incur no liabilities, under this Agreement or the other Credit
Documents.


                          SECTION 10.  MISCELLANEOUS

                 10.1 Amendments and Waivers. Neither this Agreement nor any
other Credit Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection. The Required Lenders may, or, with the written consent of the
Required Lenders, the Administrative Agent may, from time to time, (a) enter
into with the Borrower written amendments, supplements or modifications hereto
and to the other Credit Documents for the purpose of adding any provisions to
this Agreement or the other Credit Documents or changing in any manner the
rights of the Lenders or of the Borrower hereunder or thereunder or (b) waive,
on such terms and conditions as the Required Lenders or the Administrative
Agent, as the case may be, may specify in such instrument, any of the
requirements of this Agreement or the other Credit Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver
and no such amendment, supplement or modification shall (i) reduce the amount
or extend any scheduled date of maturity of any Loan, extend the expiration of
any Letter of Credit beyond the Revolving Credit Termination Date, or reduce
the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof, in each case without the consent of each
Lender affected thereby, or increase the commitment of any Lender or extend the
expiry of the commitment of any Lender without the consent of such Lender, or
(ii) amend, modify or waive any



                                       84

<PAGE>





provision of this subsection or reduce the percentage specified in the
definition of Required Lenders or Requisite Class Lenders, or consent to the
assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement and the other Credit Documents, in each case without the
written consent of all the Lenders, or (iii) release all or substantially all
of the Collateral or release all or substantially all of the Credit Parties
from their Guarantee Obligations under the Credit Document without the consent
of all Lenders, or (iv) amend, modify or waive any provision of Section 9
without the written consent of the then Agents, (v) amend, modify or waive any
provision of subsection 2.1(b), any other provision of this Agreement relating
to the Swing Line Loans or the Swing Line Note without the written consent of
the Swing Line Lender, or (vi) amend, modify or waive any provision of this
Agreement or any other Credit Document which would directly and adversely
affect the Arrangers or the Agents or the Issuing Lender or the Swing Line
Lender without the written consent of the Arranger, the Agents or the Issuing
Lender or the Swing Line Lender, as the case may be. In addition to the
foregoing, no amendment, modification, termination or waiver of any provision
of subsection 2.5 or subsection 2.6 which has the effect of changing any
interim scheduled payments, voluntary or mandatory prepayments (or the
applications thereof) or Commitment reductions applicable to any Class (an
"Affected Class") in a manner that disproportionately disadvantages such Class
relative to the other Class shall be effective without the written concurrence
of the Requisite Class Lenders of the Affected Class (it being understood and
agreed that any amendment, modification, termination or waiver of any provision
which only postpones or reduces any interim scheduled payment, voluntary or
mandatory prepayment or Commitment reduction from those set forth in subsection
2.6 with respect to only one Class shall be deemed to not disproportionately
disadvantage the other Class and, therefore, shall not require the consent of
Requisite Class Lenders of such other Class). Any such waiver and any such
amendment, supplement or modification shall apply equally to each of the
Lenders and shall be binding upon the Borrower, the Lenders, the Agents and the
Issuing Lender and all future holders of the Loans. Any extension of a Letter
of Credit by the Issuing Lender shall be treated hereunder as issuance of a new
Letter of Credit. In the case of any waiver, the Borrower, the Lenders and the
Agents and the Issuing Lender shall be restored to their former positions and
rights hereunder and under the other Credit Documents, and any Default or Event
of Default waived shall be deemed to be cured and not continuing; no such
waiver shall extend to any subsequent or other Default or Event of Default or
impair any right consequent thereon.

                 10.2 Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by
facsimile transmission) and, unless otherwise expressly provided herein, shall

Borrower shall have an obligation hereunder to the Lender or any Agent with
respect to any indemnified liabilities incurred by any Agents, Arranger or the
Issuing Lender or any Lender as a result of any Materials of Environmental
Concern that are first manufactured, emitted, generated, treated, released,
spilled, stored or disposed of on, at or from any Property or any violation of
any Environmental Law, which in any case first occurs on or with respect to
such Property (i) after the Property is transferred to any Agent, Arranger,
Issuing Lender or any Lender or their successors or assigns by foreclosure
sale, deed in lieu of foreclosure, or similar transfer or, following such
transfer, (ii) in connection with, but prior to, the sale, leasing or other
transfer of such Property by such Agent, Arranger, Issuing Lender, or any
Lender or their successors or assigns to one or more third parties; provided,
however, that the Borrower shall have no obligation hereunder to any Agent or
the Issuing Lender or any Lender with respect to otherwise indemnified
liabilities arising from the gross negligence or willful misconduct of such
Agent or the Issuing Lender or any such Lender, or with respect to otherwise
indemnified liabilities following the sale, leasing or other transfer of such
Property to one or more third parties. The agreements in this subsection shall
survive repayment of the Loans and all other amounts payable hereunder.

                 10.6 Successors and Assigns; Participation and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Agents and their respective successors and assigns,
except that the Borrower may not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

                 (b) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time sell to one or more banks or
other entities ("Participants") participating interests in any Loan owing to
such Lender or any other interest of such Lender hereunder and under the other
Credit Documents. In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement to
the other parties to this Agreement shall remain unchanged, such Lender shall
remain solely responsible for the performance thereof, such Lender shall remain
the holder of any such Loan for all purposes under this Agreement and the other
Credit Documents, and the Borrower and the Agents shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Credit Documents. No Lender
shall be entitled to create in favor of any Participant, in the participation
agreement pursuant to which such Participant's participating interest shall be
created or otherwise, any right to vote on, consent to or approve any matter
relating to this Agreement or any other Credit Document except for those
specified in clauses (i) and (ii) of the proviso to subsection 10.1. The
Borrower agrees that if amounts outstanding under this Agreement are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall, to the maximum
extent permitted by applicable law, be deemed to have the right of setoff in
respect of its participating interest in amounts owing under this Agreement to
the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement; provided that, in purchasing
such participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in subsection 10.7(a)
as fully as if it were a Lender hereunder. The Borrower also agrees that each
Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16
with respect to its participation in the Letters of Credit, the Commitments and
the Loans outstanding from time to time as if it was a Lender; provided that in
the case of subsection 2.15, such Participant shall have complied with the
requirements of said Section; provided, further, that no Participant shall be
entitled to receive any greater amount pursuant to any such subsection than the
transferor Lender would have been entitled to receive in respect of the amount
of the participation transferred by such transferor Lender to such Participant
had no such transfer occurred.

                 (c) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time and from time to time assign to
any Lender, any affiliate thereof or, in the case of Lender that is an
investment fund which is regularly engaged in making, purchasing or investing
in loans or securities, any other such fund which is under common management
with such Lender, or, with the consent of the Borrower and the Agents (which in
each case shall not be unreasonably withheld), to an additional bank, fund
which is regularly engaged in making, purchasing or investing in loans or
securities, or financial institution (an "Assignee") all or any part of its
rights and obligations under this Agreement and the other Credit Documents
pursuant to an Assignment and Acceptance, substantially in the form of Exhibit
G, executed by such Assignee, such



                                       88

<PAGE>





assigning Lender (and, in the case of an Assignee that is not then a Lender or
an affiliate thereof, by the Borrower and the Agents) and delivered to the
Administrative Agent for its acceptance and recording in the Register with a
copy to the Syndication Agent, provided that, in the case of any such
assignment to an additional bank or financial institution, (A) either (x) such
assignment is of all the rights and obligations of the assigning Lender or (y)
the sum of the aggregate principal amount of the Loans, the aggregate amount of
the L/C Obligations and the aggregate amount of the unused Commitments being
assigned and, if such assignment is of less than all of the rights and
obligations of the assigning Lender, the sum of the aggregate principal amount
of the Loans, the aggregate amount of the L/C Obligations and the aggregate
amount of the unused Commitments remaining with the assigning Lender are each
not less than $5,000,000 (or such lesser amount as may be agreed to by the
Borrower and the Agents) and (B) each Assignee which is a Non-U.S. Lender shall
comply with the provisions of clause (A) of subsection 2.15(b) hereof, or, with
the prior written consent of the Borrower, which shall not be unreasonably
withheld, the provisions of clause (B) of subsection 2.15(b) hereof (and, in
either case, with all of the other provisions of subsection 2.15(b) hereof).
Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance, (x) the
Assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with a Commitment as set forth therein and (y) the assigning Lender
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such assigning Lender
shall cease to be a party hereto). Notwithstanding any provision of this
paragraph (c) and paragraph (f) of this subsection, the consent of the Borrower
shall not be required for any assignment which occurs at any time when any of
the events described in Section 8(f) shall have occurred and be continuing.

                 (d) The Administrative Agent, on behalf of the Borrower, shall
maintain at the address of the Administrative Agent referred to in subsection
10.2 a copy of each Assignment and Acceptance delivered to it and a register
(the "Register") for the recordation of the names and addresses of the Lenders
and Commitments of and principal amounts of the Loans of each Type owing to,
each Lender from time to time and the registered owners of the Obligations
evidenced by the Notes. The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register as the
owner of a Loan, a Note or other Obligation hereunder as the owner thereof for
all purposes of this Agreement and the other Credit Documents, notwithstanding
any notice to the contrary. Any assignment of any Loan or other obligation
evidenced by a Note shall be effective only upon appropriate entries with
respect thereto being made in the Register. Any assignment or transfer of all
or part of an Obligation evidenced by a Note shall be registered in the
Register only upon surrender for registration of assignment or transfer of the
Note evidencing such Obligation, duly endorsed by (or accompanied by a written
instrument of assignment or transfer duly executed by) the holder thereof, and
thereupon one or more new Notes shall be issued to the designated Assignee and
the old Note shall be returned by the Administrative Agent to the Borrower
marked "cancelled."

                 (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof, by the Borrower and the Agents)
together with payment to the Administrative Agent of a registration and
processing fee of $3,000 (provided that no such payment shall be required
whenever LCPI or BOA is the assigning Lender), the Administrative Agent shall
(i) promptly accept such Assignment and Acceptance and (ii) on the effective
date determined pursuant thereto record the information contained therein in
the Register and give notice of such acceptance and recordation to the Lenders
and the Borrower.

                 (f) The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
subject to the provisions of subsection 10.15, any and all financial
information in such Lender's possession concerning the Borrower and its
Affiliates which has been delivered to such Lender by or on behalf of the
Borrower pursuant to this Agreement or which has been delivered to such Lender
by or on behalf of the Borrower in connection with such Lender's credit
evaluation of the Borrower and its Affiliates prior to becoming a party to this
Agreement.

                 (g) If, pursuant to this subsection 10.6, any interest in this
Agreement or any Loan is transferred to any Transferee which would be a
Non-U.S. Lender upon the effectiveness of such transfer, the assigning Lender
shall cause such Transferee, concurrently with the effectiveness of such
transfer, (i) to represent to the assigning Lender (for the benefit of the
assigning Lender, the Administrative Agent and the Borrower) that under
applicable law and treaties no U.S. Taxes will be required to be withheld by
the Administrative Agent, the Borrower or the assigning Lender with respect to
any payments to be made to such Transferee in respect of the Loans, (ii) to
furnish to the assigning Lender (and, in the case of any Assignee registered in
the Register, the Administrative Agent and the Borrower such Internal Revenue
Service Forms required to be furnished pursuant to subsection 2.15(b) and (iii)
to agree (for the benefit of the assigning Lender, the Administrative Agent and
the Borrower) to be bound by the provisions of subsection 2.15(b).

                 (h) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

                 10.7 Adjustments; Set-off. (a) If any Lender (a "benefitted
Lender") shall at any time receive any payment of all or part of its Loans or
the Reimbursement Obligations owing to it, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by
set-off, pursuant to events or proceedings of the nature referred to in Section
8(f), or otherwise), in a greater proportion than any such payment to or
collateral received by any other Lender, if any, in respect of such other
Lender's Loans or the Reimbursement Obligations owing to it, or interest
thereon, such benefitted Lender shall purchase for cash from the other Lenders
a participating interest in such portion of each such other Lender's Loans or
the Reimbursement Obligations owing to it, or shall provide such other Lenders
with the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefitted Lender to



                                       90

<PAGE>





share the excess payment or benefits of such collateral or proceeds ratably
with each of the Lenders; provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such benefitted Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery, but without interest.

                 (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower. Each Lender agrees
promptly to notify the Borrower and the Administrative Agent after any such
set-off and application made by such Lender, provided that the failure to give
such notice shall not affect the validity of such set-off and application.

                 10.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission), and all of said counterparts taken
together shall be deemed to constitute one and the same instrument. A set of
the copies of this Agreement signed by all the parties shall be lodged with the
Borrower and the Administrative Agent.

                 10.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                 10.10 Integration. This Agreement and the other Credit
Documents represent the agreement of the Borrower, the Agents and the Lenders
with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by any Agent or any Lender relative
to subject matter hereof not expressly set forth or referred to herein or in
the other Credit Documents.

OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

         aggregate outstanding principal amount of Revolving Credit Loans plus
         the aggregate outstanding amount of L/C Obligations shall exceed the
         aggregate amount of the Revolving Credit Commitments, such reduction

         Loans and (y) second, to outstanding Revolving Credit Loans (in each

         provided that if the aggregate principal amount of Swing Line Loans
         and Revolving Credit Loans then outstanding is less than the amount of
         such excess (because Letters of Credit constitute a portion of such
         excess), the Borrower shall immediately, without notice or demand, to
         the extent of the balance of such excess, replace outstanding Letters
         of Credit and/or deposit an amount (but in no event greater than such

         (such deposit to be in Dollars with respect to Domestic L/Cs and the
         applicable Alternative Currency with respect to Foreign L/Cs). The
         Borrower hereby grants to the Administrative Agent, for the benefit of
         the Issuing Lender and the L/C Participants, a security interest in
         such cash collateral to secure all obligations of the Borrower under
         this Agreement and the other Credit Documents. Any amounts deposited
         in such accounts shall be released to the Borrower on any Calculation
         Date on which the aggregate outstanding principal amount of Swing Line
         Loans plus the aggregate outstanding principal amount of Revolving
         Credit Loans plus the aggregate outstanding amount of L/C Obligations
         equals or is less than the aggregate amount of the Revolving Credit
         Commitments; provided that no Default or Event of Default has occurred
         and is continuing."

         (m) Subsection 2.12(a) of the Credit Agreement is hereby amended by
(i) deleting the phrase ", fees or otherwise," in the third sentence of such
subsection and inserting the phrase "(whether in respect of Domestic L/Cs or
Foreign L/Cs), fees, expenses or otherwise," therefor and (ii) inserting at the
end of the third sentence of such subsection the phrase "; provided, that, with
respect to any Reimbursement Obligations of the Borrower arising from the
presentment to the Issuing Lender of a draft under a Foreign L/C, the Borrower
may make payment in the applicable Alternative Currency if such payment is
received by the Issuing Bank on the date such draft is paid by the Issuing
Bank".

         (n) Section 3 of the Credit Agreement is hereby stricken in its
entirety and amended to read as follows:

                          "SECTION 3 LETTERS OF CREDIT

                           3.1 L/C Commitment. (a) Subject to the terms and
         conditions hereof, the Issuing Lender, in reliance on the agreements
         of the Revolving Credit Lenders set forth in subsection 3.4(a), agrees
         to issue letters of credit ("Letters of Credit") for the account of
         the Borrower on any Business Day during the Commitment Period in such
         form as may be approved from time to time by the Issuing Lender;
         provided that the Issuing Lender shall have no obligation to issue any
         Letter of Credit if, after giving effect to such issuance, (i) the L/C
         Obligations would exceed the L/C Commitment, (ii) the Foreign L/C
         Obligations would exceed the Foreign L/C Sublimit or (iii) the
         Available Commitment with respect to Revolving Credit Loans of all
         Revolving Credit Lenders less the aggregate principal amount of the
         Swing Line Loans then outstanding would be less than zero.

                           (b) Each Domestic L/C shall (i) be denominated in
         Dollars, (ii) be a standby letter of credit issued to support
         obligations of the Borrower or any of its Subsidiaries, contingent or
         otherwise and (iii) expire no later than the fifth Business Day prior
         to the Revolving Loan Termination Date.

                           (c) Each Foreign L/C shall (i) be denominated in an
         Alternative Currency, (ii) be a standby letter of credit issued to
         support obligations of the Borrower or any of its Subsidiaries,
         contingent or otherwise, and (iii) expire no later than the fifth
         Business Day prior to the Revolving Loan Termination Date. For
         purposes of this Agreement, the amount deemed outstanding under each
         Foreign L/C at any time, and the amount of the Borrower's
         Reimbursement Obligations under subsection 3.5 for any amounts paid by
         the Issuing Lender in connection with any Foreign L/C, shall be the
         Dollar Equivalent, as determined on the most recent Calculation Date,
         of (x) such Letter of Credit or (y) the Reimbursement Amount (as
         defined in Subsection 3.5(a)), as applicable.

                           (d) Each Letter of Credit shall be subject to the
         Uniform Customs and, to the extent not inconsistent therewith,
         Domestic L/Cs shall also be subject to the laws of the State of New
         York.

                           (e) The Issuing Lender shall not at any time be
         obligated to issue any Letter of Credit hereunder if (i) such issuance
         would conflict with, or cause the Issuing Lender or any L/C
         Participant to exceed any limits imposed by, any applicable
         Requirement of Law or any policies of the Issuing Lender or (ii) in
         the case of any Foreign L/C, it has determined that it cannot provide
         such Letter of Credit in the applicable Alternative Currency.

                           3.2 Procedure for Issuance of Letters of Credit. The
         Borrower may from time to time request that the Issuing Lender issue a
         Letter of Credit at any time prior to the fifth Business Day prior to
         the Revolving Loan Termination Date by delivering to the Issuing
         Lender with a copy to the Administrative Agent at its address for
         notices specified herein an Application therefor, completed to the
         satisfaction of the Issuing Lender, and such other certificates,
         documents and other papers and information as the Issuing Lender may
         reasonably request. Upon receipt of any Application, the Issuing
         Lender will process such Application and the certificates, documents
         and other papers and information delivered to it in connection
         therewith in accordance with its customary procedures and shall
         promptly issue the Letter of Credit requested thereby (but in no event
         shall the Issuing Lender be required to issue any Letter of Credit
         earlier than three Business Days after its receipt of the Application
         therefor and all such other certificates, documents and other papers
         and information relating thereto) by issuing the original of such
         Letter of Credit to the beneficiary thereof or as otherwise may be
         agreed by the Issuing Lender and the Borrower. The Issuing Lender
         shall furnish a copy of such Letter of Credit to the Borrower and the
         Administrative Agent (with copies for each Lender) promptly following
         the issuance thereof.

                           3.3 Fees, Commissions and Other Charges. (a) The
         Borrower shall pay to the Administrative Agent, for the account of the
         Issuing Lender and the L/C Participants, a letter of credit fee with
         respect to each Letter of Credit, computed for the period from and
         including the date of issuance of such Letter of Credit to the
         expiration

                                       7


<PAGE>



         date of such Letter of Credit at a rate per annum equal to the
         Applicable Margin then in effect for Eurodollar Loans, of the Dollar
         Equivalent of the aggregate face amount of Letters of Credit
         outstanding, payable in arrears on each L/C Fee Payment Date and on
         the Revolving Loan Termination Date; provided, that, with respect to
         any Foreign L/C, the Dollar Equivalent of the face amount of such
         Letter of Credit shall be recalculated on each Calculation Date during
         the period that such Letter of Credit is outstanding. Such fee shall
         be payable to the Administrative Agent to be shared ratably among the
         Revolving Credit Lenders in accordance with their respective
         Commitment Percentages with respect to Revolving Credit Loans. In
         addition, the Borrower shall pay to the Issuing Lender, for its sole
         account, a fee equal to 0.1250% per annum of the Dollar Equivalent of
         the aggregate face amount of outstanding Letters of Credit payable
         quarterly in arrears on each L/C Fee Payment Date and on the Revolving
         Loan Termination Date; provided, that, with respect to any Foreign
         L/C, the Dollar Equivalent of the face amount of such Letter of Credit
         shall be recalculated on each Calculation Date during the period that
         such Letter of Credit is outstanding.

                           (b) In addition to the foregoing fees and
         commissions, the Borrower shall pay or reimburse the Issuing Lender
         for such normal and customary costs and expenses as are incurred or
         charged by the Issuing Lender in issuing, effecting payment under,
         amending or otherwise administering any Letter of Credit.

                           (c) The Administrative Agent shall, promptly
         following its receipt thereof, distribute to the Issuing Lender and
         the L/C Participants all fees and commissions received by the
         Administrative Agent for their respective accounts pursuant to this
         subsection.

                           3.4 L/C Participation. (a) The Issuing Lender
         irrevocably agrees to sell and hereby sells to each L/C Participant,
         and, to induce the Issuing Lender to issue Letters of Credit
         hereunder, each L/C Participant irrevocably agrees to accept and
         purchase and hereby accepts and purchases from the Issuing Lender, on
         the terms and conditions hereinafter stated, for such L/C
         Participant's own account and risk an undivided interest equal to such
         L/C Participant's Commitment Percentage with respect to Revolving
         Credit Loans from time to time in effect in the Issuing Lender's
         obligations and rights under each Letter of Credit issued hereunder
         and the amount of each draft paid by the Issuing Lender thereunder.
         Each L/C Participant unconditionally and irrevocably agrees with the
         Issuing Lender that, if a draft is paid under any Letter of Credit for
         which the Issuing Lender is not reimbursed in full by the Borrower in
         accordance with the terms of this Agreement, such L/C Participant
         shall pay to the Issuing Lender upon demand in Dollars at the Issuing
         Lender's address for notices specified herein an amount equal to such
         L/C Participant's then Commitment Percentage with respect to Revolving
         Credit Loans of the Dollar Equivalent of the amount of such draft
         (determined on the date such draft is paid), or any part thereof,
         which is not so reimbursed; provided that, if such demand is made
         prior to 11:00 A.M., New York City time, on a Business Day, such L/C
         Participant shall make such payment to the Issuing Lender prior to the
         end of

                                       8


<PAGE>



         such Business Day and otherwise such L/C Participant shall make such
         payment on the next succeeding Business Day.

                           (b) If any amount required to be paid by any L/C
         Participant to the Issuing Lender pursuant to subsection 3.4(a) in
         respect of any unreimbursed portion of any payment made by the Issuing
         Lender under any Letter of Credit is paid to the Issuing Lender within
         three Business Days after the date such payment is due, such L/C
         Participant shall pay to the Issuing Lender on demand an amount equal
         to the product of (i) such amount, times (ii) the daily average
         Federal Funds Effective Rate, as quoted by the Issuing Lender, during
         the period from and including the date such payment is required to the
         date on which such payment is immediately available to the Issuing
         Lender, times (iii) a fraction the numerator of which is the number of
         days that elapse during such period and the denominator of which is
         360. If any such amount required to be paid by any L/C Participant
         pursuant to subsection 3.4(a) is not in fact made available to the
         Issuing Lender by such L/C Participant within three Business Days
         after the date such payment is due, the Issuing Lender shall be
         entitled to recover from such L/C Participant, on demand, such amount
         with interest thereon calculated from such due date at the rate per
         annum applicable to Base Rate Loans hereunder. A certificate of the
         Issuing Lender submitted to any L/C Participant with respect to any
         amounts owing under this subsection shall be conclusive in the absence
         of manifest error.

                           (c) Whenever, at any time after the Issuing Lender
         has made payment under any Letter of Credit and has received from any
         L/C Participant its pro rata share of such payment in accordance with
         subsection 3.4(a), the Issuing Lender receives any payment related to
         such Letter of Credit (whether directly from the Borrower or
         otherwise, including proceeds of collateral applied thereto by the
         Issuing Lender), or any payment of interest on account thereof, the
         Issuing Lender will, if such payment is received prior to 11:00 A.M.,
         New York City time, on a Business Day, distribute to such L/C
         Participant its pro rata share thereof prior to the end of such
         Business Day and otherwise the Issuing Lender will distribute such
         payment on the next succeeding Business Day; provided, however, that
         in the event that any such payment received by the Issuing Lender and
         distributed to the L/C Participants shall be required to be returned
         by the Issuing Lender, each such L/C Participant shall return to the
         Issuing Lender the portion thereof previously distributed by the
         Issuing Lender to it.

                           3.5 Reimbursement Obligation of the Borrower. (a)
         The Borrower agrees to reimburse the Issuing Lender on the same
         Business Day on which the Issuing Lender notifies the Borrower of the
         date and amount of a draft presented under any Letter of Credit and
         paid by the Issuing Lender provided such notice is received by 1:00
         P.M., New York City time, on such Business Day, and the next Business
         Day if such notice is received after such time. The Issuing Lender
         shall provide notice to the Borrower on each Business Day on which a
         draft is presented indicating the Dollar Equivalent of the amount of
         (i) such draft so paid (and, in the case of a Foreign L/C, the amount
         of such draft so paid stated in the applicable Alternative Currency)
         and (ii) any

                                       9


<PAGE>



         taxes, fees, charges or other costs or expenses incurred by the
         Issuing Lender in connection with such payment ((i) and (ii)
         collectively with any interest accruing pursuant to paragraph (b)
         below, the "Reimbursement Amount"). Each such payment shall be made to
         the Issuing Lender at its address for notices specified herein in
         lawful money of the United States of America and in immediately
         available funds; provided, that, with respect to any Reimbursement
         Obligations of the Borrower arising from the presentment to the
         Issuing Lender of a draft under a Foreign L/C, the Borrower may make
         payment in the applicable Alternative Currency if such payment is
         received by the Issuing Bank on the date such draft is paid by the
         Issuing Bank.

                           (b) Interest shall be payable on the Dollar
         Equivalent of any and all amounts remaining unpaid by the Borrower
         under this subsection from the date a draft presented under any Letter
         of Credit is paid by the Issuing Lender until payment in full (i) at
         the rate which would be payable on any Loans that are Base Rate Loans
         at such time until such payment is required to be made pursuant to
         subsection 3.5(a), and (ii) thereafter, at the rate which would be
         payable on any Loans that are Base Rate Loans at such time which were
         then overdue.

                           (c) For the avoidance of doubt, subject to the
         provisos in the third sentence of subsection 2.12(a) and the last
         sentence of subsection 3.5(a) of this Agreement, all payments due from
         the Borrower hereunder in respect of Foreign L/Cs (and Reimbursement
         Obligations in connection therewith) shall be made in Dollars as
         provided in subsection 2.12 of this Agreement.

                           3.6 Obligations Absolute. (a) The Borrower's
         obligations under subsection 3.5(a) shall be absolute and
         unconditional under any and all circumstances and irrespective of any
         set-off, counterclaim or defense to payment which the Borrower may
         have or have had against the Issuing Lender, any L/C Participant or
         any beneficiary of a Letter of Credit.

                           (b) The Borrower also agrees with the Issuing Lender
         that the Issuing Lender shall not be responsible for, and the
         Borrower's Reimbursement Obligations under subsection 3.5(a) shall not
         be affected by, among other things, (i) the validity or genuineness of
         documents or of any endorsements thereon, even though such documents
         shall in fact prove to be invalid, fraudulent or forged (unless the
         Issuing Lender has knowledge of such invalidity, fraud or forgery),
         (ii) any dispute between or among the Borrower and any beneficiary of
         any Letter of Credit or any other party to which such Letter of Credit
         may be transferred, or (iii) any claims whatsoever of the Borrower
         against any beneficiary of such Letter of Credit or any such
         transferee.

                           (c) Neither the Issuing Lender nor any L/C
         Participant shall be liable for any error, omission, interruption or
         delay in transmission, dispatch or delivery of any message or advice,
         however transmitted, in connection with any Letter of Credit, except

                                       10


<PAGE>



         for errors or omissions caused by the Issuing Lender's gross
         negligence or willful misconduct.

                           (d) The Borrower agrees that any action taken or
         omitted by the Issuing Lender under or in connection with any Letter
         of Credit or the related drafts or documents, if done in the absence
         of gross negligence or willful misconduct and in accordance with the
         standards of care specified in the Uniform Commercial Code of the
         State of New York, shall be binding on the Borrower and shall not
         result in any liability of the Issuing Lender or any L/C Participant
         to the Borrower.

                           3.7 Letter of Credit Payments. If any draft shall be
         presented for payment under any Letter of Credit, the Issuing Lender
         shall promptly notify the Borrower and the Administrative Agent of the
         date and the Dollar Equivalent of the amount thereof (and, in the case
         of a Foreign L/C, the amount thereof stated in the applicable
         Alternative Currency). If any draft shall be presented for payment
         under any Letter of Credit, the responsibility of the Issuing Lender
         to the Borrower in connection with such draft shall, in addition to
         any payment obligation expressly provided for in such Letter of
         Credit, be limited to determining that the documents (including each
         draft) delivered under such Letter of Credit in connection with such
         presentment appear on their face to be in conformity with such Letter
         of Credit.

                           3.8 Application. To the extent that any provision of
         any Application related to any Letter of Credit is inconsistent with
         the provisions of this Section 3, the provisions of this Section 3
         shall govern and control.

                           3.9 Determination of Exchange Rate. On each
         Calculation Date with respect to each outstanding Foreign L/C, the
         Issuing Bank shall determine the Exchange Rate as of such Calculation
         Date with respect to the applicable Alternative Currency and shall
         promptly notify the Administrative Agent and the Borrower thereof and
         of the Dollar Equivalent of all Foreign L/Cs outstanding on such
         Calculation Date. The Exchange Rate so determined shall become
         effective on such Calculation Date and shall remain effective until
         the next succeeding Calculation Date."

         (o) Subsection 4.21 of the Credit Agreement is hereby amended by
inserting at the end of the first sentence of such subsection the phrase "and,
upon consummation of the issuance of the New Subordinated Notes, the
representations and warranties contained in the New Subordinated Debt Documents
will be true and correct in all material respects as of the date of the
respective agreements".

         (p) Subsection 5.2(a) of the Credit Agreement is hereby amended by

         that the Foreign L/C Obligations exceed the Foreign L/C Sublimit based
         on the most recent Calculation Date (such excess, the "Foreign L/C
         Overdrawn Amount"), deposit an amount equal to the Foreign L/C
         Overdrawn Amount in Dollars in a cash collateral account opened by the
         Administrative Agent established for the benefit of the Revolving
         Credit Lenders; provided, that the Borrower shall not be required to
         make such deposits in such cash collateral account if (i) the Foreign
         L/C Overdrawn Amount is equal to or less than 10% of the Foreign L/C
         Sublimit, (ii) the Available Commitments with respect to Revolving

         compliance with its obligations under this Agreement. The Borrower
         hereby grants to the Administrative Agent, for the benefit of the
         Issuing Lender and the L/C Participants, a security interest in such
         cash collateral to secure all obligations of the Borrower under this
         Agreement and the other Credit Documents. Any amounts deposited in

         Subordinated Notes; provided that, to the extent that any of the Net
         Proceeds of the New Subordinated Notes are used by the Borrower to
         prepay any of the Loans, such prepayments shall be subject to the
         provisions of Subsection 2.6(iv) of this Agreement (notwithstanding
         the fact that such Net Proceeds are not otherwise required to be
         applied to the prepayment of the Loans);"

         (af) The following shall be added to the Credit Agreement as
subsection 10.16 thereof:

                  "10.16 Conversion of Currencies. (a) If, for the purpose of
         obtaining judgment in any court, it is necessary to convert a sum
         owing hereunder in one currency into another currency, each party
         hereto agrees, to the fullest extent that it may effectively do so,
         that the rate of exchange used shall be that at which in accordance
         with normal banking procedures in the relevant jurisdiction the first
         currency could be purchased with such other currency on the Business
         Day immediately preceding the date on which final judgment is given.

                  (b) The obligations of the Borrower in respect of any sum due
         to any party hereto or any holder of the obligations owing hereunder

         currency (the "Judgment Currency") other than the currency in which
         such sum is stated to be due hereunder (the "Agreement Currency"), be
         discharged only to the extent that, on the Business Day following
         receipt by the Applicable Creditor of any sum adjudged to be so due in
         the Judgment Currency, the Applicable Creditor may in accordance with
         normal banking procedures in the relevant jurisdiction purchase the
         Agreement Currency with the Judgment Currency; if the amount of the
         Agreement Currency so purchased is less than the sum originally due to
         the Applicable Creditor in the Agreement Currency, the Borrower
         agrees, as a separate obligation and notwithstanding any such
         judgment, to indemnify the Applicable Creditor against such loss. The
         obligations of the Borrower contained in this subsection 10.16 shall
         survive the termination of this Agreement and the payment of all other
         amounts owing hereunder."

amended Schedule I attached hereto.

         SECTION 2. WAIVERS

and complete payment and performance by each of the other Credit Parties when

            2.1(c) Holdings agrees that the Guaranteed Obligations may at any
time and from time to time exceed the amount of the liability of Holdings

            2.1(d) The guarantee contained in this Section 2 shall remain in

no Loans or Letters of Credit may be outstanding).

            2.1(e) No indefeasible payment made by any Credit Party or any other
Person or received or collected by any of the Agents or the Lenders by virtue of
any action or proceeding or any set-off or appropriation or application at any
time or from time to time in reduction of or in payment of the Guaranteed
Obligations shall be deemed to release the liability of Holdings hereunder, and
Holdings shall, notwithstanding any such payment (other than any payment made by
Holdings in respect of the Guaranteed Obligations or any payment received or
collected from Holdings in respect of the Guaranteed Obligations), remain liable
for the Guaranteed Obligations up to the maximum liability of Holdings hereunder
until the Guaranteed Obligations are paid in full, no Loan or Letter of Credit
shall be outstanding and the Commitments are terminated.

            2.2 No Subrogation. Notwithstanding any payment made by Holdings

Credit Parties on account of the Guaranteed Obligations are paid in full, no
Letter of Credit shall be outstanding and the Commitments are terminated. If any
amount shall be paid to Holdings on account of such

                                       3
<PAGE>

subrogation rights at any time when all of the Guaranteed Obligations shall not
have been paid in full, such amount shall be held by Holdings in trust for the
Agents and the Lenders, segregated from other funds of Holdings. and shall,
forthwith upon receipt by Holdings, be turned over to the Administrative Agent
in the exact form received by Holdings (duly indorsed by Holdings to the
Administrative Agent, if required), to be applied against the Guaranteed
Obligations, whether matured or unmatured, in such order as the Required Lenders
may determine.

            2.3 Amendments, etc. with respect to the Guaranteed Obligations.
Holdings shall remain obligated hereunder notwithstanding that, without any
reservation of rights against Holdings and without notice to or further assent
by Holdings, any demand for payment of any of the Guaranteed Obligations made by
any of the Agents or Lenders may be rescinded by such Agent or Lender and any of
the Guaranteed Obligations continued, and the Guaranteed Obligations, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by any of the Agents
or Lenders, and the Credit Agreement, the other Credit Documents and any other
documents executed and delivered in connection therewith may be amended,
restated, modified, supplemented or terminated, in whole or in part, as the
Administrative Agent (or the Required Lenders or all Lenders, as the case may
be) may deem advisable from time to time, and any collateral security, guarantee
or right of offset at any time held by any of the Agents or Lenders for the
payment of the Guaranteed Obligations may be sold, exchanged, waived,
surrendered or released. None of the Agents or Lenders shall have any obligation
to protect, secure, perfect or insure any Lien at any time held by it as
security for the Guaranteed Obligations or for the guarantee contained in this
Section 2 or any property subject thereto.

            2.4 Guarantee Absolute and Unconditional. Holdings waives any and
all notice of the creation, renewal, extension or accrual of any of the
Guaranteed Obligations and notice of or proof of reliance by any of the Agents
or Lenders upon the guarantee contained in this Section 2 or acceptance of the
guarantee contained in this Section 2; the Guaranteed Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon the guarantee
contained in this Section 2; and all dealings between the Credit Parties, on the
one hand, and the Agents and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon the
guarantee contained in this Section 2. Holdings waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon any
of the Credit Parties with respect to the Guaranteed Obligations. Holdings
understands and agrees that the guarantee contained in this Section 2 shall be
construed as a continuing, absolute and unconditional guarantee of payment
without regard to (a) the validity or enforceability of the Credit Agreement,
this Agreement or any other Credit Document, any of the Guaranteed Obligations
or any other collateral security therefor or guarantee or right of offset with
respect thereto at any time or from time to time held by any of the Agents or
Lenders, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by
any of the other Credit Panics or any other Person against any of the Agents or
the Lenders, or (c) any other circumstance whatsoever (with or without notice to
or knowledge of any of the Credit Parties) which constitutes, or might be
construed to constitute, an equitable or legal discharge of any of the other
Credit Parties for the Guaranteed Obligations, or of Holdings under the
guarantee contained in this Section 2, in bankruptcy or in any other instance.
When making any demand hereunder or otherwise pursuing its rights and remedies
hereunder against Holdings, any of the Agents or Lenders may, but shall be under
no obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against any of the other Credit Parties or any other
Person or against any collateral security or guarantee for the Guaranteed
Obligations or any right of offset with respect thereto, and any failure by the
any of the Agents or Lenders

                                       4
<PAGE>

to make any such demand. to pursue such other rights or remedies or to collect
any payments from any of the other Credit Parties or any other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of any of the other Credit Parties or any other
Person or any such collateral security, guarantee or right of offset, shall not
relieve Holdings of any obligation or liability hereunder, and shall not impair
or affect the rights and remedies, whether express, implied or available as a
matter of law, of any of the Agents or Lenders against Holdings. For the

                  2.1(a) Each of the Guarantors hereby, jointly and severally,
      unconditionally and irrevocably, guarantees to the Administrative Agent,
      for the ratable benefit of the Lenders and the Agents and their respective
      successors, indorsees, transferees and assigns, the prompt and complete
      payment and performance by each of the other Credit Parties when due
      (whether at the stated maturity, by acceleration or otherwise) of such
      other Credit Party's Obligations (collectively, the "Guaranteed
      Obligations"). The liability of the Guarantors hereunder shall be joint
      and several with the Obligations of all other Guarantors.

                  2.1(b) Anything herein or in any other Credit Document to the
      contrary notwithstanding, the maximum liability of each Guarantor
      hereunder and under the other Credit Documents shall in no event exceed

      applicable federal and state laws relating to the insolvency of debtors
      without rendering such Guarantor insolvent.

                  2.1(c) Each Guarantor agrees that the Guaranteed Obligations
      may at any time and from time to time exceed the amount of the liability
      of such Guarantor hereunder without impairing the guarantee contained in
      this Section 2 or affecting the rights and remedies of the


                                       2
<PAGE>

      Administrative Agent, on behalf of the other Agents and the Lenders
      hereunder.

                  2.1(d) The guarantee contained in this Section 2 shall remain
      in full force and effect until all the Guaranteed Obligations and the
      obligations of each Guarantor under this Agreement shall have been
      satisfied by payment in full, no Letter of Credit shall be outstanding and
      the Commitments shall be terminated, notwithstanding that from time to
      time during the term of the Credit Agreement, no Loans or Letters of
      Credit may be outstanding.

                  2.1(e) No indefeasible payment made by any Credit Party or any
      other Person or received or collected by any of the Agents or the Lenders
      by virtue of any action or proceeding or any set-off or appropriation or
      application at any time or from time to time in reduction of or in payment
      of the Guaranteed Obligations shall be deemed to release the liability of
      any Guarantor hereunder, and each Guarantor shall, notwithstanding any
      such payment (other than any payment made by such Guarantor in respect of
      the Guaranteed Obligations or any payment received or collected from such
      Guarantor in respect of the Guaranteed Obligations), remain liable for the
      Guaranteed Obligations up to the maximum liability of such Guarantor
      hereunder until the Guaranteed Obligations are paid in full, no Loan or
      Letter of Credit shall be outstanding and the Commitments are terminated.

            2.2 Right of Contribution. Each Guarantor hereby agrees that to the
extent that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder which has not paid
its proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 2.3. The provisions of
this Section 2.2 shall in no respect limit the obligations and liabilities of
any Guarantor to the Administrative Agent and the Lenders, and each Guarantor
shall remain jointly and severally liable to the Administrative Agent and the
Lenders for the full amount guaranteed by such Guarantor hereunder.

            2.3 No Subrogation. Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
any of the Agents or Lenders, no Guarantor shall be entitled to be subrogated to
any of the rights of any of the Agents or Lenders against the Other Credit
Parties or any collateral security or guarantee or right of offset held by any
of the Agents or Lenders for the payment of all or any portion of the Guaranteed
Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from any of the Other Credit Parties or any other
Guarantor in respect of payments made by such Credit Party hereunder, until all
amounts owing to the Agents and the Lenders by the other Credit Parties on
account of any of the Obligations are paid in full, no Letter of Credit shall be
outstanding and the Commitments are terminated. If any amount shall be paid to
any Guarantor on account of such subrogation rights at any time when all of the
Guaranteed Obligations shall not have been paid in full, such amount shall be
held by such Guarantor in trust for the Agents and the Lenders, segregated from
other funds of such Guarantor, and shall, forthwith upon receipt by such
Guarantor, be turned over to the Administrative Agent in the exact form received
by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent,
if required), to be applied against the Guaranteed Obligations, whether matured
or unmatured, in such order as the Administrative Agent may determine.

            2.4 Amendments. etc. with respect to the Guaranteed Obligations.
Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of


                                       3
<PAGE>

the Guaranteed Obligations made by any of the Agents or Lenders may be rescinded
by such Agent and any of the Guaranteed Obligations continued, and the
Guaranteed Obligations, or the liability of any other Person upon or for any
part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by any of the Agents or Lenders, and the Credit
Agreement, the other Credit Documents and any other documents executed and
delivered in connection therewith may be amended, restated, modified,
supplemented or terminated, in whole or in part, as the Administrative Agent (or
the Required Lenders or all Lenders, as the case may be) may deem advisable from
time to time, and any collateral security guarantee or right of offset at any
time held by any of the Agents or Lenders for the payment of the Guaranteed
Obligations may be sold, exchanged, waived, surrendered or released. None of the
Agents or Lenders shall have any obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Guaranteed
Obligations or for the guarantee contained in this Section 2 or any property
subject thereto.

            2.5 Guarantee Absolute and Unconditional. Each Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Guaranteed Obligations and notice of or proof of reliance by any of the Agents
or Lenders upon the guarantee contained in this Section 2 or acceptance of the
guarantee contained in this Section 2; the Guaranteed Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon the guarantee
contained in this Section 2; and all dealings between the Borrower and any of
the Guarantors, on the one hand, and the Agents and the Lenders, on the other
hand, likewise shall be conclusively presumed to have been had or consummated in
reliance upon the guarantee contained in this Section 2. Each Guarantor waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon any of the Credit Parties with respect to the Guaranteed
Obligations. Each Guarantor understands and agrees that the guarantee contained
in this Section 2 shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity or enforceability of the
Credit Agreement, this Agreement or any other Credit Document, any of the
Guaranteed Obligations or any other collateral security therefor or guarantee or
right of offset with respect thereto at any time or from time to time held by
any of the Agents or Lenders, (b) any defense, set-off or counterclaim (other
than a defense of payment or performance) which may at any time be available to
or be asserted by any of the other Credit Parties or any other Person against
any of the Agents or Lenders, or (c) any other circumstance whatsoever (with or
without notice to or knowledge of any of the Credit Parties) which constitutes,
or might be construed to constitute, an equitable or legal discharge of any of
the Credit Parties for the Guaranteed Obligations, or of such Guarantor under
the guarantee contained in this Section 2, in bankruptcy or in any other
instance. When making any demand hereunder or otherwise pursuing its rights and
remedies hereunder against any Guarantor, any of the Agents or Lenders may, but
shall be under no obligation to, make a similar demand on or otherwise pursue
such rights and remedies as it may have against any of the other Credit Parties,
any other Guarantor or any other Person or against any collateral security or
guarantee for the Guaranteed Obligations or any right of offset with respect
thereto, and any failure by any of the Agents or Lenders to make any such
demand, to pursue such other rights or remedies or to collect any payments from
any of the other Credit Parties, any other Guarantor or any other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of any of the other Credit Parties, any other
Guarantor or any other Person or any such collateral security, guarantee or
right of offset, shall not relieve any Guarantor of any obligation or liability
hereunder, and shall not impair or affect the rights and remedies, whether
express, implied or available as a matter of law, of any of the Agents or
Lenders against any Guarantor. For the purposes hereof "demand" shall include
the commencement and continuance of any legal proceedings.

            2.6 Reinstatement. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Guaranteed Obligations is rescinded
or must otherwise be restored or returned by and of the Agents or Lenders upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of any of
the Credit Parties, or upon or as a result of the appointment of a receiver,

the Borrower's knowledge shall, for the purposes of this Section 3.1, be deemed
to be a reference to such Guarantor's knowledge.

                              SECTION 4. COVENANTS

such Guarantor shall take, or shall refrain from taking, as the case may be,

or to refrain from taking such action by any of the Credit Parties.

instrument pursuant to Section 5.1), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default. No failure to exercise, nor any delay in
exercising, on the part of any of the Agents or Lenders, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by any of the Agents or Lenders of any right or remedy hereunder on any
one occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent, on behalf of the other Agents and the Lenders, would
otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

            To induce the Agents and the Lenders to enter into the Credit
Agreement and to induce the Agents and the Lenders to make their respective
extensions of credit to or for the benefit of the Borrower thereunder, Holdings

      valid perfected security interests in all of the Collateral in favor of
      the Administrative Agent, for the ratable benefit of the Agents and the
      Lenders, as collateral security for the Obligations, enforceable in
      accordance with the terms hereof against all creditors of Holdings and any
      Persons purporting to purchase any Collateral from Holdings, subject to
      the effects of bankruptcy, insolvency, fraudulent conveyance,
      reorganization, moratorium and other similar laws relating to or affecting
      creditors' rights generally, general equitable principles (whether
      considered in a proceeding in equity or at law) and an implied covenant of
      good faith and fair dealing; and

                  3.3(b) are prior to all other Liens on the Collateral in
      existence on the date hereof except for unrecorded Liens and other Liens
      or permitted by the Credit Agreement which have priority over the Liens on

                  3.6(b) All the shares of the Pledged Stock have been duly and
      validly issued and are fully paid and nonassessable.

                  3.6(c) Holdings is the record and beneficial owner of, and has
      good and marketable title to, the Pledged Stock pledged by it hereunder,
      free of any and all Liens or options in favor of, or claims of, any other
      Person, except the security interest created by this Agreement and other
      Liens permitted by the Credit Agreement which have priority by operation
      of law.

paid in full, no Letter of Credit shall be outstanding and the Commitments shall
have terminated:

            4.1 Covenants in Credit Agreement. Holdings shall take, or shall
refrain from taking, as the case may be, each action that is necessary to be
taken or not taken, as the case may be, so that no Default or Event of Default
is caused by the failure to take such action or to refrain from taking such
action by any of the Credit Parties.

            4.2 Delivery of Instruments and Chattel Paper. If any amount payable
under or in connection with any of the Collateral shall be or become evidenced
by any Instrument or Chattel Paper,

<PAGE>

such Instrument or Chattel Paper shall be promptly delivered to the
Administrative Agent, duly indorsed in a manner satisfactory to the
Administrative Agent, to be held as Collateral pursuant to this Agreement.

            4.3 Payment of Obligations. Holdings will pay and discharge or
otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all material taxes, assessments and governmental charges or levies
imposed upon the Collateral or in respect of income or profits therefrom, as
well as all material claims of any kind (including, without limitation, claims
for labor, materials and supplies) against or with respect to the Collateral,
except that no such charge need be paid if the amount or validity thereof is
currently being contested in good faith by appropriate proceedings, reserves in
conformity with GAAP with respect thereto have been provided on the books of
Holdings and such proceedings could not reasonably be expected to result in the
sale, forfeiture or loss of any material portion of the Collateral or any
interest therein.

            4.4 Maintenance of Perfected Security Interest; Further
Documentation.

                  4.4(a) Holdings shall maintain the security interest created
      by this Agreement as a perfected security interest having at least the
      priority described in subsection 3.3 and shall defend such security
      interest against the claims and demands of all Persons whomsoever.

                  4.4(b) Holdings will furnish to the Agents and the Lenders
      from time to time statements and schedules further identifying and
      describing the Collateral and such other reports in connection with the
      Collateral as the Administrative Agent may reasonably request, all in
      reasonable detail.

                  4.4(c) At any time and from time to time, upon the written
      request of the Administrative Agent, and at the sole expense of Holdings,
      Holdings will promptly and duly execute and deliver, and have recorded,
      such further instruments and documents and take such further actions as
      the Administrative Agent may reasonably request for the purpose of
      obtaining or preserving the full benefits of this Agreement and of the
      rights and powers herein granted, including, without limitation, the
      filing of any financing or continuation statements under the Uniform
      Commercial Code (or other similar laws) in effect in any jurisdiction with
      respect to the security interests created hereby.

            4.5 Changes in Locations, Name, etc. Holdings will not, except upon
15 days' prior written notice to the Administrative Agent and delivery to the
Administrative Agent of all additional executed financing statements and other
documents reasonably requested by the Administrative Agent to maintain the
validity, perfection and priority of the security interests provided for herein,
change its name, identity or corporate structure to such an extent that any
financing statement filed by the Administrative Agent in connection with this
Agreement would become misleading.

            4.6 Notices. Holdings will advise the Agents and the Lenders
promptly, in reasonable detail, of:

                  4.6(a) any Lien (other than security interests created hereby
      or Liens permitted under the Credit Agreement) on any of the Collateral
      which would adversely affect the ability of the Administrative Agent to
      exercise any of its remedies hereunder, and


                                       8
<PAGE>

                  4.6(b) of the occurrence of any other event of which it is
      aware which could reasonably be expected to have a material adverse effect
      on the enforceability, or perfection or priority of, the security
      interests purported to be created hereby.

            4.7 Pledged Securities.

                  4.7(a) If Holdings shall become entitled to receive or shall
      receive any stock certificate (including, without limitation, any
      certificate representing a stock dividend or a distribution in connection
      with any reclassification, increase or reduction of capital or any
      certificate issued in connection with any reorganization), option or
      rights in respect of the Capital Stock of any Issuer, whether in addition
      to, in substitution of, as a conversion of, or in exchange for, any shares
      of the Pledged Stock, or otherwise in respect thereof, Holdings shall
      accept the same as the agent of the Agents and the Lenders, hold the same
      in trust for the Agents and the Lenders and deliver the same forthwith to
      the Administrative Agent in the exact form received, duly indorsed by
      Holdings to the Administrative Agent, if required, together with an
      undated stock power covering such certificate duly executed in blank by
      Holdings and with, if the Administrative Agent so requests, signature
      guaranteed, to be held by the Administrative Agent, subject to the terms
      hereof, as additional collateral security for the Obligations. Any sums
      paid upon or in respect of the Pledged Stock upon the liquidation or
      dissolution of any Issuer shall be paid over to the Administrative Agent
      to be held by it hereunder as additional collateral security for the
      Obligations, and in case any distribution of capital shall be made on or
      in respect of the Pledged Stock or any property shall be distributed upon
      or with respect to the Pledged Stock pursuant to the recapitalization or
      reclassification of the capital of any Issuer or pursuant to the
      reorganization thereof, the property so distributed shall, unless
      otherwise subject to a perfected security interest in favor of the
      Administrative Agent, be delivered to the Administrative Agent to be held
      by it hereunder as additional collateral security (or except as provided
      in the Credit Agreement) for the Obligations. Except as provided in the
      Credit Agreement, if any sums of money or property so paid or distributed
      in respect of the Pledged Stock under circumstances described in this
      Section 4.7(a) shall be received by Holdings, Holdings shall, until such
      money or property is paid or delivered to the Administrative Agent, hold
      such money or property in trust for the Lenders, segregated from other
      funds of Holdings, as additional collateral security for the Obligations.

                  4.7(b) Except as provided in the Credit Agreement, without the
      price written consent of the Administrative Agent, Holdings will not (i)
      vote to enable, or take any other action to permit, any Issuer to issue

      (iii) create, incur or permit to exist any Lien or option in favor of, or
      any claim of any Person with respect to, any of the Pledged Stock or
      Proceeds thereof, or any interest therein, except for the security
      interests created by this Agreement or (iv) enter into any agreement or
      undertaking restricting the right or ability of Holdings or the
      Administrative Agent to sell, assign or transfer any of the Pledged Stock
      or Proceeds thereof.

                         SECTION 5. REMEDIAL PROVISIONS

            5.1 Pledged Stock.

                  5.1(a) Unless an Event of Default shall have occurred and be
      continuing and the Administrative Agent shall have given notice to
      Holdings of the Administrative Agent's intent to exercise its
      corresponding rights pursuant to subsection 5.3(b), Holdings shall be
      permitted to receive all cash dividends paid in respect of the Pledged
      Stock and all payments made in respect of the Pledged Notes, in each case
      paid in the normal course of business of the relevant Issuer and
      consistent with past practice, to the extent permitted in the Credit
      Agreement, and to exercise all voting and corporate rights with respect to
      the Pledged Stock; provided, however, that no vote shall be cast or
      corporate right exercised or other action taken which, in the
      Administrative Agent's reasonable judgment, would materially impair the
      Collateral or which would result in any violation of any provision of the
      Credit Agreement, this Agreement or any other Credit Document.

                  5.1(b) If an Event of Default shall occur and be continuing
      and the Administrative Agent shall give notice of its intent to exercise
      such rights to Holdings, (i) the Administrative Agent shall have the right
      to receive any and all cash dividends, payments or other Proceeds paid in
      respect of the Pledged Stock and make application thereof to Obligations
      in such order as the Administrative Agent may determine, and (ii) any or
      all of the Pledged Stock shall be registered in the name of the
      Administrative Agent or its nominee, and the Administrative Agent or its
      nominee may thereafter exercise (x) all voting, corporate and other rights
      pertaining to such Pledged Stock at any meeting of shareholders of the
      relevant Issuer or Issuers or otherwise and (y) any and all rights of
      conversion, exchange and subscription and any other rights, privileges or
      options pertaining to such Pledged Stock as if it were the absolute owner
      thereof (including, without limitation, the right to exchange at its
      discretion any and all of the Pledged Stock upon the merger,
      consolidation, reorganization, recapitalization or other fundamental
      change in the corporate structure of any Issuer, or upon the exercise by
      Holdings or the Administrative Agent of any right, privilege or option
      pertaining to such Pledged Stock, and in connection therewith, the right
      to deposit and deliver any and all of the Pledged Stock with any
      committee, depositary, transfer agent, registrar or other designated
      agency upon such terms and conditions as the Administrative Agent may
      determine), all without liability except to account for property actually
      received by it, but the Administrative Agent shall have no duty to
      Holdings to exercise any such right, privilege or option and shall not be
      responsible for any failure to do so or delay in so doing.

                  5.1(c) Holdings hereby authorizes and instructs each Issuer of
      any Pledged Stock pledged by Holdings hereunder to (i) comply with any
      instruction received by it from the Administrative Agent in writing that
      (x) states that an Event of Default has occurred and is continuing and (y)
      is otherwise in accordance with the terms of this Agreement, without any
      other or further instructions from Holdings, and Holdings agrees that each
      Issuer shall be fully protected in so complying, and (ii) unless otherwise
      expressly permitted hereby, pay any dividends or other payments with
      respect to the Pledged Stock directly to the Administrative Agent.

            5.2 Proceeds to be Turned Over To Administrative Agent. In addition
to the rights of the Agents and the Lenders specified in subsection 5.1 with
respect to payments of Receivables, if an Event of Default shall occur and be
continuing, all Proceeds received by Holdings consisting of cash,


                                       10
<PAGE>

checks and other near-cash items shall be held by Holdings in trust for the
Agents and the Lenders, segregated from other funds of Holdings, and shall,
forthwith upon receipt by Holdings, be turned over to the Administrative Agent
in the exact form received by Holdings (duly indorsed by Holdings to the
Administrative Agent, if required). All Proceeds received by the Administrative
Agent hereunder shall be held by the Administrative Agent in a Collateral
Account maintained under its sole dominion and control. All Proceeds while held
by the Administrative Agent in a Collateral Account (or by Holdings in trust for
the Administrative Agent and the Lenders) shall continue to be held as
collateral security for all the Obligations and shall not constitute payment
thereof until applied as provided in subsection 5.5.

            5.3 Application of Proceeds. At such intervals as may be agreed upon
by Holdings and the Administrative Agent, or, if an Event of Default shall have
occurred and be continuing, at any time at the Administrative Agent's election,
the Administrative Agent may apply all or any part of Proceeds held in any
Collateral Account in payment of the Obligations in such order as required by
the Credit Agreement, and any part of such funds which are not required as
collateral security for the Obligations shall be paid over from time to time by
the Administrative Agent to Holdings or to whomsoever may be lawfully entitled
to receive the same. Any balance of such Proceeds remaining after the
Obligations shall have been paid in full, no Letters of Credit shall be
outstanding and the Commitments shall have terminated shall be paid over to
Holdings or to whomsoever may be lawfully entitled to receive the same.

            5.4 Code and Other Remedies. If an Event of Default shall occur and
be continuing. the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted to them in this Agreement
and in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the New York UCC
or any other applicable law. Without limiting the generality of the foregoing,
the Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon the Borrower or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of any of the Agents or Lenders or elsewhere
upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption
of any credit risk. Any Agents or Lenders shall have the right upon any such
public sale or sales, and, to the extent permitted by law, upon any such private
sale or sales, to purchase the whole or any part of the Collateral so sold, free
of any right or equity of redemption in the Borrower, which right or equity is
hereby waived and released. Holdings further agrees, at the Administrative
Agent's request, to assemble the Collateral and make it available to the
Administrative Agent at places which the Administrative Agent shall reasonably
select, whether at Holdings' premises or elsewhere. The Administrative Agent
shall apply the net proceeds of any action taken by it pursuant to this
subsection 5.6, after deducting all reasonable costs and expenses of every kind
incurred in connection therewith or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of the
Agents and the Lenders hereunder, including, without limitation, reasonable
attorneys' fees and disbursements, to the payment in whole or in part of the
Obligations, in such order as the Administrative Agent may elect, and only after
such application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9-504(1)(c) of the New York UCC, need the Administrative Agent account for


                                       11
<PAGE>

the surplus, if any, to Holdings. To the extent permitted by applicable law,
Holdings waives all claims, damages and demands it may acquire against any
Agents or Lenders arising out of the exercise by them of any rights hereunder.
If any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 15 days before such sale or other disposition.

            5.5 Registration Rights.

                  5.5(a) If the Administrative Agent shall determine to exercise
      its right to sell any or all of the Pledged Stock pursuant to subsection
      5.6, and if in the opinion of the Administrative Agent it is necessary or
      advisable to have the Pledged Stock, or that portion thereof to be sold,
      registered under the provisions of the Securities Act, Holdings will cause
      the Issuer thereof to (i) execute and deliver, and cause the directors and
      officers of such Issuer to execute and deliver, all such instruments and
      documents, and do or cause to be done all such other acts as may be, in
      the opinion of the Administrative Agent, necessary or advisable to
      register the Pledged Stock, or that portion thereof to be sold, under the
      provisions of the Securities Act, (ii) use its commercially reasonable
      efforts to cause the registration statement relating thereto to become
      effective and to remain effective for a period of one year from the date
      of the first public offering of the Pledged Stock, or that portion thereof
      to be sold, and (iii) make all amendments thereto and/or to the related
      prospectus which, in the opinion of the Administrative Agent, are
      necessary or advisable, all in conformity with the requirements of the
      Securities Act and the rules and regulations of the Securities and
      Exchange Commission applicable thereto. Holdings agrees to cause such
      Issuer to comply with the provisions of the securities or "Blue Sky" laws
      of any and all jurisdictions which the Administrative Agent shall
      designate and to make available to its security holders, as soon as
      practicable, an earnings statement (which need not be audited) which will
      satisfy the provisions of Section 11(a) of the Securities Act.

                  5.5(b) Holdings recognizes that the Administrative Agent may
      be unable to effect a public sale of any or all the Pledged Stock, by
      reason of certain prohibitions contained in the Securities Act and
      applicable state securities laws or otherwise, and may be compelled to
      resort to one or more private sales thereof to a restricted group of
      purchasers which will be obliged to agree, among other things, to acquire
      such securities for their own account for investment and not with a view
      to the distribution or resale thereof. Holdings acknowledges and agrees
      that any such private sale may result in prices and other terms less
      favorable than if such sale were a public sale and, notwithstanding such
      circumstances, agrees that any such private sale shall be deemed to have
      been made in a commercially reasonable manner. The Administrative Agent
      shall be under no obligation to delay a sale of any of the Pledged Stock
      for the period of time necessary to permit the Issuer thereof to register
      such securities for public sale under the Securities Act, or under
      applicable state securities laws, even if such Issuer would agree to do
      so.

                  5.5(c) Holdings agrees to use its commercially reasonable
      efforts to do or cause to be done all such other acts as may be necessary
      to make such sale or sales of all or any portion of the Pledged Stock
      pursuant to this subsection 5.7 valid and binding and in compliance with
      any and all other applicable Requirements of Law. Holdings further agrees
      that a breach of any of the covenants contained in this subsection 5.7
      will cause irreparable injury to the Agents and the Lenders, that the
      Agents and the Lenders have no adequate remedy at law in respect of such
      breach and, as a consequence, that each and every covenant contained in
      this subsection 5.7 shall


                                       12
<PAGE>

      be specifically enforceable against Holdings, and Holdings hereby waives
      and agrees not to assert any defenses against an action for specific
      performance of such covenants except for a defense that no Event of
      Default has occurred under the Credit Agreement.

            5.6 Waiver; Deficiency. Holdings waives and agrees not to assert any
rights or privileges which it may acquire under Section 9-112 of the New York
UCC. Holdings shall remain liable for any deficiency if the proceeds of any sale
or other disposition of the Collateral are insufficient to pay its Obligations
and the fees and disbursements of any attorneys employed by the Administrative
Agent or any Lender to collect such deficiency.

            (along with the goodwill of the business to which any such

of this Agreement shall be sufficient as a financing statement or other filing
or recording document or instrument for filing or recording in any jurisdiction.

      accordance with the terms hereof against all creditors of the Borrower and
      any Persons purporting to purchase any Collateral from the Borrower,
      subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
      reorganization, moratorium and other similar laws relating to or affecting
      creditors' rights generally, general equitable principles (whether
      considered in a proceeding in equity or at law) and an implied covenant of
      good faith and fair dealing; and

                  3.2(b) are prior to all other Liens on the Collateral in
      existence on the date hereof except for unrecorded Liens and other Liens

      validly issued and are fully paid and nonassessable.

                  3.5(c) Each of the Pledged Notes constitutes the legal, valid
      and binding obligation of the obligor with respect thereto, enforceable in
      accordance with its terms, subject to the effects of bankruptcy,
      insolvency, fraudulent conveyance, reorganization, moratorium and other
      similar laws relating to or affecting creditors' rights generally, general
      equitable principles (whether considered in a proceeding in equity or at
      law) and an implied covenant of good faith and fair dealing.

                  3.5(d) The Borrower is the record and beneficial owner of, and
      has good and marketable title to, the Pledged Securities pledged by it

      request of the Administrative Agent, and at the sole expense of the
      Borrower, the Borrower will promptly and duly execute and deliver, and

      in connection with this Agreement would become misleading.

            4.6 Notices. The Borrower will advise the Agents and the Lenders
promptly, in reasonable detail, of:

                  4.6(a) any Lien (other than security interests created hereby
      or Liens permitted under the Credit Agreement) on any of the Collateral
      which would adversely affect the ability of the Administrative Agent to
      exercise any of its remedies hereunder; and

                  4.6(b) of the occurrence of any other event of which it is
      aware which could reasonably be expected to have a material adverse effect

      Obligations. Any sums paid upon or in respect of the Pledged Securities

      of money or property so paid or distributed in respect of the Pledged
      Securities under circumstances described in this Section 4.7(a) shall be

      property in trust for the Lenders, segregated from other funds of the
      Borrower, as additional collateral security for the Obligations.

                  4.7(b) Except as provided in the Credit Agreement, without the
      prior written consent of the Administrative Agent, the Borrower will not

      other securities convertible into or granting the right to purchase or
      exchange for any stock or other equity securities of any nature of any
      Issuer, (ii) sell, assign, transfer, exchange, or otherwise dispose of, or
      grant any option with respect to, the Pledged Securities or Proceeds
      thereof (except pursuant to a transaction expressly permitted by the
      Credit Agreement), (iii) create, incur or permit to exist any Lien or

      Borrower will not (i) grant any extension of the time of payment of any
      Receivable, (ii) compromise or settle any Receivable for less than the
      full amount thereof, (iii) release, wholly or partially, any Person liable
      for the payment of any Receivable, (iv) allow any credit or discount
      whatsoever on any Receivable or (v) amend, supplement or modify any
      Receivable in any manner that could adversely affect the value thereof.

                  4.8(b) The Borrower will deliver to the Administrative Agent a
      copy of each material demand, notice or document received by it that

      Contracts) and (y) take all such other action as the Administrative Agent
      reasonably deems necessary to comply with the provisions of the Assignment
      of Claims Act of 1940, as amended, and the Borrower shall, upon written

      such Notices of Assignment executed by the appropriate officer or officers
      of the appropriate Government Authority; (iv) with respect to each
      contract, agreement or transaction pursuant to which any State or any
      political subdivision thereof is a party, execute and deliver all notices

      of such State to ensure that the Administrative Agent has a valid and
      perfected first priority security interest in such contract, agreement or
      transaction to the extent required by the terms of the Credit Agreement;
      and (v) execute and file such financing or continuation statements, or
      amendments thereto, and such other instruments or notices, as may be
      necessary, or as the Administrative Agent may reasonably request, in order
      to perfect and preserve the pledge, assignment and security interest
      granted or purported to be granted hereby.

            4.9 Contracts.

                  4.9(a) The Borrower will perform and comply in all material
      respects with all its obligations under its material Contracts.

                  4.9(b) The Borrower will not amend, modify, terminate or waive
      any provision of any material Contract in any manner which could
      reasonably be expected to materially adversely affect the value of such
      material Contract as Collateral.

                  4.9(c) The Borrower will exercise promptly and diligently each
      and every right which it may have under each material Contract (other than
      any right of termination).

                  4.9(d) The Borrower will deliver to the Administrative Agent a
      copy of each material demand, notice or document received by it relating
      in any way to any material Contract that questions the validity or
      enforceability of such material Contract.

                  4.9(e) The Borrower represents and warrants that the
      Government Contracts referenced on Schedule 6 constitute all Government
      Contracts having a value equal to or in excess of $1.0 million to which
      the Borrower is a party on the date hereof.

                  4.9(f) The Borrower will, when required under Section 6.13 of

      Person from time to time such documents, instruments, certificates or
      reports and take such further steps relating to the Collateral consisting
      of the Receivables in respect of Government Contracts which (i) the
      Administrative Agent deems necessary to perfect, preserve or protect its


                                       12

      security interest in such Collateral or (ii) shall be necessary to comply

                  4.9(g) The Borrower hereby covenants and agrees that it will
      not enter any Restricted Government Contracts unless the Borrower
      determines in good faith that it must agree to a prohibition on the
      assignment of Receivables arising under such Government Contract in order
      to obtain such Government Contract and gives the Administrative Agent
      written notice that it has entered into such Restricted Government
      Contract.

            4.10 Intellectual Property.

                  4.10(a) The Borrower (either itself or through licensees) will
      (i) continue to use each material Trademark on each and every trademark
      class of goods applicable to its current line as reflected in its current
      catalogs, brochures and price lists in order to maintain such Trademark in
      full force free from any claim of abandonment for non-use, except where
      the failure to do so could not, individually or in the aggregate, be
      expected to have a Material Adverse Effect, (ii) maintain as in the past
      the quality of products and services offered under such material
      Trademark, (iii) use such material Trademark with the appropriate notice
      of registration and all other notices and legends required by applicable
      Requirements of Law, (iv) not adopt or use any mark which is confusingly
      similar or a colorable imitation of such material Trademark unless the
      Administrative Agent, for the ratable benefit of the Lenders, shall obtain
      a perfected security interest in such mark pursuant to this Agreement, (v)
      not do any act or knowingly omit to do any act whereby such material
      Trademark may become invalidated or impaired in any way, and (vi) use
      reasonable efforts to prevent any licensee or sublicensee thereof from

      act, whereby any material Patent may become forfeited, abandoned or
      dedicated to the public and will use reasonable efforts to prevent any

      material Patent may become forfeited, abandoned or dedicated to the
      public.

                  4.10(c) The Borrower will not do any act or knowingly omit to
      do any act and will use reasonable efforts to prevent any licensee or
      sublicensee thereof from doing any act or knowingly omitting to do any act
      whereby any material portion of the material Copyrights may become
      invalidated or otherwise impaired. The Borrower will not do any act and
      will use reasonable efforts to prevent any sublicensee from doing any act
      whereby any material portion of the Copyrights may fall into the public
      domain.

                  4.10(d) The Borrower (either itself or through licensees) will

      infringe the intellectual property rights of any other Person.

                  4.10(e) The Borrower will notify the Administrative Agent and
      the Lenders immediately if it knows that any application or registration
      relating to any material Intellectual Property may become forfeited,
      abandoned or dedicated to the public, or of any material adverse
      determination or development (including, without limitation, the
      institution of, or any such


                                       13
<PAGE>

      determination or development in, any proceeding in the United States
      Patent and Trademark Office, the United States Copyright Office or any
      court or tribunal in any country) regarding the Borrower's ownership of,
      or the validity of, any material Intellectual Property or the Borrower's
      right to register the same or to own and maintain the same.

                  4.10(f) Whenever the Borrower, either by itself or through any
      agent, employee, licensee or designee, shall file an application for the
      registration of any Intellectual Property with the United States Patent
      and Trademark Office, the United States Copyright Office or any similar
      office or agency in any other country or any political subdivision
      thereof, the Borrower shall report such filing to the Administrative Agent
      within 30 Business Days after the last day of the fiscal quarter in which
      such filing occurs. Upon request of the Administrative Agent, the Borrower
      shall execute and deliver, and have recorded, any and all agreements,
      instruments, documents, and papers as the Administrative Agent may
      reasonably request to evidence the Agents' and the Lenders' security
      interest in any Copyright, Patent or Trademark and the goodwill and
      general intangibles of the Borrower relating thereto or represented
      thereby.

                  4.10(g) The Borrower will take all reasonable and necessary
      steps, including, without limitation, in any proceeding before the United
      States Patent and Trademark Office, the United States Copyright Office or
      any similar office or agency in any other country or any political
      subdivision thereof, to maintain and pursue each application (and to
      obtain the relevant registration) and to maintain each registration of the
      material Intellectual Property, including, without limitation, filing of
      any necessary applications for renewal, affidavits of use and affidavits
      of incontestability, and paying all necessary fees, except to the extent
      the failure to do so could not, individually or in the aggregate, be
      expected to have a Material Adverse Effect.

                  4.10(h) In the event that any material Intellectual Property
      is infringed, misappropriated or diluted by a third party, the Borrower
      shall (i) take such actions as the Borrower shall reasonably deem
      appropriate under the circumstances to protect such Intellectual Property
      and (ii) if such Intellectual Property is of material economic value to
      the Borrower and its Subsidiaries taken as a whole, promptly notify the
      Administrative Agent after it learns thereof and sue for infringement,
      misappropriation or dilution, seek injunctive relief where appropriate and
      recover any and all damages for such infringement, misappropriation or
      dilution.

                         SECTION 5. REMEDIAL PROVISIONS

            5.1 Certain Matters Relating to Receivables.

                  5.1(a) The Administrative Agent shall have the right to make
      test verifications of the Receivables in any manner and through any medium
      that it reasonably considers advisable, and the Borrower shall furnish all
      such assistance and information as the Administrative Agent may require in
      connection with such test verifications. At any time and from time to
      time, upon the Administrative Agent's request and at the expense of the
      Borrower, the Borrower shall cause independent public accountants or
      others satisfactory to the Administrative Agent to furnish to the
      Administrative Agent reports showing reconciliations, aging and test
      verifications of, and trial balances for, the Receivables.


                                       14
<PAGE>

                  5.1(b) The Administrative Agent hereby authorizes the Borrower
      to collect the Borrower's Receivables, subject to the Administrative
      Agent's direction and control, and the Administrative Agent may curtail or
      terminate said authority at any time after the occurrence and during the
      continuance of an Event of Default. If required by the Administrative
      Agent at any time after the occurrence and during the continuance of an
      Event of Default, any payments of Receivables, when collected by the
      Borrower, (i) shall be forthwith (and, in any event, within two Business
      Days) deposited by the Borrower in the exact form received, duly indorsed
      by the Borrower to the Administrative Agent if required, in a Collateral
      Account maintained under the sole dominion and control of the
      Administrative Agent, subject to withdrawal by the Administrative Agent
      for the account of the Lenders only as provided in subsection 5.5, and
      (ii) until so turned over, shall be held by the Borrower in trust for the
      Agents and the Lenders, segregated from other funds of the Borrower. Each
      such deposit of Proceeds of Receivables shall be accompanied by a report
      identifying in reasonable detail the nature and source of the payments
      included in the deposit. In addition, the Administrative Agent shall have
      the right at any time, upon the occurrence and during the continuance of
      an Event of Default and upon written notice to the Borrower of its
      intention to do so, to require the Borrower to prepare notices of
      assignment for each Government Contract for which it has not previously
      delivered a notice of assignment pursuant to Section 6.13 of the Credit
      Agreement and to file such notices of assignment (and any notice of
      assignment delivered to the Administrative Agent pursuant to Section 6.13
      of the Credit Agreement) with the appropriate contracting officer of the
      appropriate Government Authority and to otherwise notify the account
      debtors or obligors under any Receivables of the assignment of such
      Receivables to the Administrative Agent and to direct such account debtors
      or obligors to make payment of all amounts due or to become due to the
      Borrower thereunder directly to the Administrative Agent and, upon such
      notification and at the expense of the Borrower, to enforce collection of
      any such Receivables, and to adjust, settle or compromise the amount or
      payment thereof, in the same manner and to the same extent as the Borrower
      might have done. After receipt by the Borrower of the notice from the
      Administrative Agent referred to in the proviso to the preceding sentence,
      (i) all amounts and proceeds (including instruments) received by the
      Borrower in respect of the Receivables shall be received in trust for the
      benefit of the Administrative Agent, the Agents, the Lenders, the Issuing
      Banks and the other Holders hereunder, shall be segregated from other
      funds of the Borrower and shall be forthwith paid over to the
      Administrative Agent in the same form as so received (with any necessary
      indorsement) to be applied to the Obligations in accordance with Section 8
      of the Credit Agreement and (ii) the Borrower shall not adjust, settle or
      compromise the amount or payment of any Account, release wholly or partly
      any account debtor or obligor thereof, or allow any credit or discount
      thereon.

                  5.1(c) At the Administrative Agent's request, the Borrower
      shall deliver to the Administrative Agent all original and other documents
      evidencing, and relating to, the agreements and transactions which gave
      rise to the Receivables, including, without limitation, all original
      orders, invoices and shipping receipts.

            5.2 Communications with Obligors; Borrower Remains Liable.

                  5.2(a) The Administrative Agent in its own name or in the name
      of others may at any time after the occurrence and during the continuance
      of an Event of Default communicate with obligors under the Receivables and
      parties to the Contracts to verify with them to the


                                       15
<PAGE>

      Administrative Agent's satisfaction the existence, amount and terms of any
      Receivables or Contracts.

                  5.2(b) Upon the request of the Administrative Agent at any
      time after the occurrence and during the continuance of an Event of
      Default, the Borrower shall notify obligors on the Receivables and parties
      to the Contracts that the Receivables and the Contracts have been assigned
      to the Administrative Agent for the ratable benefit of the Lenders and
      that payments in respect thereof shall be made directly to the
      Administrative Agent.

                  5.2(c) Anything herein to the contrary notwithstanding, the
      Borrower shall remain liable under each of the Receivables and Contracts
      to observe and perform all the conditions and obligations to be observed
      and performed by it thereunder, all in accordance with the terms of any
      agreement giving rise thereto. Neither the Administrative Agent nor any
      Lender shall have any obligation or liability under any Receivable (or any
      agreement giving rise thereto) or Contract by reason of or arising out of
      this Agreement or the receipt by any Agent or Lender of any payment
      relating thereto, nor shall any Agent or Lender be obligated in any manner
      to perform any of the obligations of the Borrower under or pursuant to any
      Receivable (or any agreement giving rise thereto) or Contract, to make any
      payment, to make any inquiry as to the nature or the sufficiency of any
      payment received by it or as to the sufficiency of any performance by any
      party thereunder, to present or file any claim, to take any action to
      enforce any performance or to collect the payment of any amounts which may
      have been assigned to it or to which it may be entitled at any time or
      times.

            5.3 Pledged Stock.

            5.3(a) Unless an Event of Default shall have occurred and be
      continuing and the Administrative Agent shall have given notice to the
      Borrower of the Administrative Agent's intent to exercise its
      corresponding rights pursuant to subsection 5.3(b), the Borrower shall be
      permitted to receive all cash dividends paid in respect of the Pledged
      Stock and all payments made in respect of the Pledged Notes, in each case
      paid in the normal course of business of the relevant Issuer and
      consistent with past practice, to the extent permitted in the Credit
      Agreement, and to exercise all voting and corporate rights with respect to
      the Pledged Securities; provided, however, that no vote shall be cast or
      corporate right exercised or other action taken which, in the
      Administrative Agent's reasonable judgment, would materially impair the
      Collateral or which would result in any violation of any provision of the
      Credit Agreement, this Agreement or any other Credit Document.

                  5.3(b) If an Event of Default shall occur and be continuing
      and the Administrative Agent shall give notice of its intent to exercise
      such rights to the Borrower, (i) the Administrative Agent shall have the
      right to receive any and all cash dividends, payments or other Proceeds
      paid in respect of the Pledged Securities and make application thereof to
      the Borrower Obligations in such order as the Administrative Agent may
      determine, and (ii) any or all of the Pledged Securities shall be
      registered in the name of the Administrative Agent or its nominee, and the
      Administrative Agent or its nominee may thereafter exercise (x) all
      voting, corporate and other rights pertaining to such Pledged Securities
      at any meeting of shareholders of the relevant Issuer or Issuers or
      otherwise and (y) any and all rights of conversion, exchange and
      subscription and any other rights, privileges or options pertaining to
      such Pledged Securities as if it were the


                                       16
<PAGE>

      absolute owner thereof (including, without limitation, the right to
      exchange at its discretion any and all of the Pledged Securities upon the
      merger, consolidation, reorganization, recapitalization or other
      fundamental change in the corporate structure of any Issuer, or upon the
      exercise by the Borrower or the Administrative Agent of any right,
      privilege or option pertaining to such Pledged Securities, and in
      connection therewith, the right to deposit and deliver any and all of the
      Pledged Securities with any committee, depositary, transfer agent,
      registrar or other designated agency upon such terms and conditions as the
      Administrative Agent may determine), all without liability except to
      account for property actually received by it, but the Administrative Agent
      shall have no duty to the Borrower to exercise any such right, privilege
      or option and shall not be responsible for any failure to do so or delay
      in so doing.

                  5.3(c) The Borrower hereby authorizes and instructs each
      Issuer of any Pledged Securities pledged by the Borrower hereunder to (i)
      comply with any instruction received by it from the Administrative Agent
      in writing that (x) states that an Event of Default has occurred and is
      continuing and (y) is otherwise in accordance with the terms of this
      Agreement, without any other or further instructions from the Borrower,
      and the Borrower agrees that each Issuer shall be fully protected in so
      complying, and (ii) unless otherwise expressly permitted hereby, pay any
      dividends or other payments with respect to the Pledged Securities
      directly to the Administrative Agent.

            5.4 Proceeds to be Turned Over To Administrative Agent. In addition
to the rights of the Agents and the Lenders specified in subsection 5.1 with
respect to payments of Receivables, if an Event of Default shall occur and be
continuing, all Proceeds received by the Borrower consisting of cash, checks and
other near-cash items shall be held by the Borrower in trust for the Agents and
the Lenders, segregated from other funds of the Borrower, and shall, forthwith
upon receipt by the Borrower, be turned over to the Administrative Agent in the
exact form received by the Borrower (duly indorsed by the Borrower to the
Administrative Agent, if required). All Proceeds received by the Administrative
Agent hereunder shall be held by the Administrative Agent in a Collateral
Account maintained under its sole dominion and control. All Proceeds while held
by the Administrative Agent in a Collateral Account (or by the Borrower in trust
for the Administrative Agent and the Lenders) shall continue to be held as
collateral security for all the Obligations and shall not constitute payment
thereof until applied as provided in subsection 5.5.

            5.5 Application of Proceeds. At such intervals as may be agreed upon
by the Borrower and the Administrative Agent, or, if an Event of Default shall
have occurred and be continuing, at any time at the Administrative Agent's
election, the Administrative Agent may apply all or any part of Proceeds held in
any Collateral Account in payment of the Obligations in such order as required
by the Credit Agreement, and any part of such funds which are not required as
collateral security for the Obligations shall be paid over from time to time by
the Administrative Agent to the Borrower or to whomsoever may be lawfully
entitled to receive the same. Any balance of such Proceeds remaining after the
Obligations shall have been paid in full, no Letters of Credit shall be
outstanding and the Commitments shall have terminated shall be paid over to the
Borrower or to whomsoever may be lawfully entitled to receive the same.

            5.6 Code and Other Remedies. If an Event of Default shall occur and
be continuing, the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted to them in this Agreement
and in any other instrument or agreement securing, evidencing


                                       17
<PAGE>

or relating to the Obligations, all rights and remedies of a secured party under
the New York UCC or any other applicable law. Without limiting the generality of
the foregoing, the Administrative Agent, without demand of performance or other
demand, presentment, protest, advertisement or notice of any kind (except any
notice required by law referred to below) to or upon the Borrower or any other
Person (all and each of which demands, defenses, advertisements and notices are
hereby waived), may in such circumstances forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, lease, assign, give option or options to purchase, or otherwise
dispose of and deliver the Collateral or any part thereof (or contract to do any
of the foregoing), in one or more parcels at public or private sale or sales, at
any exchange, broker's board or office of any of the Agents or Lenders or
elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. Any Agents or Lenders shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold, free of any right or equity of redemption in the Borrower, which right
or equity is hereby waived and released. The Borrower further agrees, at the
Administrative Agent's request, to assemble the Collateral and make it available
to the Administrative Agent at places which the Administrative Agent shall
reasonably select, whether at the Borrower's premises or elsewhere. The
Administrative Agent shall apply the net proceeds of any action taken by it
pursuant to this subsection 5.6, after deducting all reasonable costs and
expenses of every kind incurred in connection therewith or incidental to the
care or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Agents and the Lenders hereunder, including,
without limitation, reasonable attorneys' fees and disbursements, to the payment
in whole or in part of the Obligations, in such order as the Administrative
Agent may elect, and only after such application and after the payment by the
Administrative Agent of any other amount required by any provision of law,
including, without limitation, Section 9-504(1)(c) of the New York UCC, need the
Administrative Agent account for the surplus, if any, to the Borrower. To the
extent permitted by applicable law, the Borrower waives all claims, damages and
demands it may acquire against any Agents or Lenders arising out of the exercise
by them of any rights hereunder. If any notice of a proposed sale or other
disposition of Collateral shall be required by law, such notice shall be deemed
reasonable and proper if given at least 15 days before such sale or other
disposition.

            5.7 Registration Rights.

                  5.7(a) If the Administrative Agent shall determine to exercise
      its right to sell any or all of the Pledged Stock pursuant to subsection
      5.6, and if in the opinion of the Administrative Agent it is necessary or
      advisable to have the Pledged Stock, or that portion thereof to be sold,
      registered under the provisions of the Securities Act, the Borrower will
      cause the Issuer thereof to (i) execute and deliver, and cause the
      directors and officers of such Issuer to execute and deliver, all such
      instruments and documents, and do or cause to be done all such other acts
      as may be, in the opinion of the Administrative Agent, necessary or
      advisable to register the Pledged Stock, or that portion thereof to be
      sold, under the provisions of the Securities Act, (ii) use its
      commercially reasonable efforts to cause the registration statement
      relating thereto to become effective and to remain effective for a period
      of one year from the date of the first public offering of the Pledged
      Stock, or that portion thereof to be sold, and (iii) make all amendments
      thereto and/or to the related prospectus which, in the opinion of the
      Administrative Agent, are necessary or advisable, all in conformity with
      the requirements of the Securities Act and the rules and regulations of
      the Securities and Exchange Commission applicable thereto. The Borrower
      agrees to cause such Issuer to comply with the provisions of the
      securities or "Blue Sky" laws of


                                       18
<PAGE>

      any and all jurisdictions which the Administrative Agent shall designate
      and to make available to its security holders, as soon as practicable, an
      earnings statement (which need not be audited) which will satisfy the
      provisions of Section 11(a) of the Securities Act.

                  5.7(b) The Borrower recognizes that the Administrative Agent
      may be unable to effect a public sale of any or all the Pledged Stock, by
      reason of certain prohibitions contained in the Securities Act and
      applicable state securities laws or otherwise, and may be compelled to
      resort to one or more private sales thereof to a restricted group of
      purchasers which will be obliged to agree, among other things, to acquire
      such securities for their own account for investment and not with a view
      to the distribution or resale thereof. The Borrower acknowledges and
      agrees that any such private sale may result in prices and other terms
      less favorable than if such sale were a public sale and, notwithstanding
      such circumstances, agrees that any such private sale shall be deemed to
      have been made in a commercially reasonable manner. The Administrative
      Agent shall be under no obligation to delay a sale of any of the Pledged
      Stock for the period of time necessary to permit the Issuer thereof to
      register such securities for public sale under the Securities Act, or
      under applicable state securities laws, even if such Issuer would agree to
      do so.

                  5.7(c) The Borrower agrees to use its commercially reasonable
      efforts to do or cause to be done all such other acts as may be necessary
      to make such sale or sales of all or any portion of the Pledged Stock
      pursuant to this subsection 5.7 valid and binding and in compliance with
      any and all other applicable Requirements of Law. The Borrower further
      agrees that a breach of any of the covenants contained in this subsection
      5.7 will cause irreparable injury to the Agents and the Lenders, that the
      Agents and the Lenders have no adequate remedy at law in respect of such
      breach and, as a consequence. that each and every covenant contained in
      this subsection 5.7 shall be specifically enforceable against the
      Borrower, and the Borrower hereby waives and agrees not to assert any
      defenses against an action for specific performance of such covenants
      except for a defense that no Event of Default has occurred under the
      Credit Agreement.

            5.8 Waiver; Deficiency. The Borrower waives and agrees not to assert
any rights or privileges which it may acquire under Section 9-112 of the New
York UCC. The Borrower shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Administrative Agent or any Lender to collect such deficiency.

                       SECTION 6. THE ADMINISTRATIVE AGENT

            6.1 Administrative Agent's Appointment as Attorney-in-Fact, etc.

                  6.1(a) The Borrower hereby irrevocably constitutes and
      appoints the Administrative Agent and any officer or agent thereof, with
      full power of substitution, as its true and lawful attorney-in-fact with
      full irrevocable power and authority in the place and stead of the
      Borrower and in the name of the Borrower or in its own name, for the
      purpose of carrying out the terms of this Agreement, to take any and all
      appropriate action and to execute any and all documents and instruments
      which may be necessary or desirable to accomplish the purposes of this
      Agreement, and, without limiting the generality of the foregoing, the
      Borrower hereby gives


                                       19
<PAGE>

      the Administrative Agent the power and right, on behalf of the Borrower,
      without notice to or assent by the Borrower, to do any or all of the
      following:

                  (i) in the name of the Borrower or its own name, or otherwise,
      take possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Receivable or Contract or with respect to any other Collateral and file
      any claim or take any other action or proceeding in any court of law or
      equity or otherwise deemed appropriate by the Administrative Agent for the
      purpose of collecting any and all such moneys due under any Receivable or
      Contract or with respect to any other Collateral whenever payable;

                  (ii) in the case of any Intellectual Property, execute and
      deliver, and have recorded, any and all agreements, instruments, documents
      and papers as the Administrative Agent may request to evidence the Agents'
      and the Lenders' security interest in such Intellectual Property and the
      goodwill and general intangibles of the Borrower relating thereto or
      represented thereby;

                  (iii) pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repairs or any insurance
      called for by the terms of this Agreement and pay all or any part of the
      premiums therefor and the costs thereof;

                  (iv) execute, in connection with any sale provided for in
      subsection, 5.6 or 5.7, any endorsements, assignments or other instruments
      of conveyance or transfer with respect to the Collateral; and

                  (v)(A) direct any party liable for any payment under any of
      the Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Administrative Agent or as the Administrative
      Agent shall direct; (B) ask or demand for, collect, and receive payment of
      and receipt for, any and all moneys, claims and other amounts due or to
      become due at any time in respect of or arising out of any Collateral; (C)
      sign and indorse any invoices, freight or express bills, bills of lading,
      storage or warehouse receipts, drafts against debtors, assignments,
      verifications, notices and other documents in connection with any of the
      Collateral; (D) commence and prosecute any suits, actions or proceedings
      at law or in equity in any court of competent jurisdiction to collect the
      Collateral or any portion thereof and to enforce any other right in
      respect of any Collateral; (E) defend any suit, action or proceeding
      brought against the Borrower with respect to any Collateral; (F) settle,
      compromise or adjust any such suit, action or proceeding and, in
      connection therewith, give such discharges or releases as the
      Administrative Agent may reasonably deem appropriate; (G) assign any
      Copyright, Patent or Trademark (along with the goodwill of the business to
      which any such Copyright, Patent or Trademark pertains), throughout the
      world for such term or terms, on such conditions, and in such manner, as
      the Administrative Agent shall in its sole discretion determine; and (H)
      generally, sell, transfer, pledge and make any agreement with respect to
      or otherwise deal with any of the Collateral as fully and completely as
      though the Administrative Agent were the absolute owner thereof for all
      purposes, and do, at the Administrative Agent's option and the Borrower's
      expense, at any time, or from time to time, all acts and things which the
      Administrative Agent deems necessary to protect,


                                       20
<PAGE>

      preserve or realize upon the Collateral and the Agents' and the Lenders'
      security interests therein and to effect the intent of this Agreement, all
      as fully and effectively as the Borrower might do.

            Anything in this subsection 6.1(a) to the contrary notwithstanding,
the Administrative Agent agrees that it will not exercise any rights under the
power of attorney provided for in this subsection 6.1(a) unless an Event of
Default shall have occurred and be continuing.

                  6.1(b) If the Borrower fails to perform or comply with any of
      its agreements contained herein, the Administrative Agent, at its option,
      but without any obligation so to do, may perform or comply, or otherwise
      cause performance or compliance, with such agreement.

                  6.1(c) The expenses of the Administrative Agent incurred in
      connection with actions undertaken as provided in this subsection 6.1,
      together with interest thereon at a rate per annum equal to the rate per
      annum at which interest would then be payable on past due Base Rate Loans
      under the Credit Agreement, from the date of payment by the Administrative
      Agent to the date reimbursed by the Borrower, shall be payable by the
      Borrower to the Administrative Agent on demand.

                  6.1(d) The Borrower hereby ratifies all that said attorneys
      shall lawfully do or cause to be done by virtue hereof. All powers,
      authorizations and agencies contained in this Agreement are coupled with
      an interest and are irrevocable until this Agreement is terminated and the
      security interests created hereby are released.

            6.2 Duty of Administrative Agent. The Administrative Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the New York UCC or
otherwise, shall be to deal with it in the same manner as the Administrative
Agent deals with similar property for its own account. Neither the
Administrative Agent, any Lender nor any of their respective officers,
directors, employees or agents shall be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Borrower or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Agents and the Lenders hereunder are solely to protect the
Agents' and the Lenders' interests in the Collateral and shall not impose any
duty upon any Agents or Lenders to exercise any such powers. The Agents and the
Lenders shall be accountable only for amounts that they actually receive as a
result of the exercise of such powers, and neither they nor any of their
officers, directors, employees or agents shall be responsible to the Borrower
for any act or failure to act hereunder, except for their own gross negligence
or willful misconduct.

            6.3 Execution of Financing Statements. Pursuant to Section 9-402 of
the New York UCC and any other applicable law, the Borrower authorizes the
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with respect to the Collateral without the
signature of the Borrower in such form and in such offices as the Administrative
Agent reasonably determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement. A photographic or other reproduction
of this Agreement shall be sufficient as a financing statement or other filing
or recording document or instrument for filing or recording in any jurisdiction.


                                       21

            6.4 Authority of Administrative Agent. The Borrower acknowledges
that the rights and responsibilities of the Administrative Agent under this
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as among the Agents and the
Lenders, be governed by the Credit Agreement and by such other agreements with
respect thereto as may exist from time to time among them, but, as among the
Agents and the Borrower, the Administrative Agent shall be conclusively presumed
to be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and the Borrower shall not be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                            SECTION 7. MISCELLANEOUS

            7.1 Amendments in Writing. None of the terms or provisions of this
Agreement may be waived, amended, restated, supplemented or otherwise modified
except in accordance with subsection 10.1 of the Credit Agreement.

            7.2 Notices. All notices, requests and demands to or upon the Agents
or the Borrower hereunder shall be effected in the manner provided for in
subsection 10.2 of the Credit Agreement.

            7.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default. No failure to exercise, nor any delay in
exercising, on the part of any of the Agents or Lenders, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by any of the Agents or Lenders of any right or remedy hereunder on any
one occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent, on behalf of the other Agents and the Lenders, would
otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

            7.4 Enforcement Expenses; Indemnification.

                  7.4(a) The Borrower agrees to pay or reimburse each of the
      Lenders and the Agents for all its reasonable costs and expenses incurred
      in collecting against the Borrower or otherwise enforcing or preserving
      any rights under this Agreement and the other Credit Documents to which
      the Borrower is a party, including, without limitation, the reasonable
      fees and disbursements of counsel to the Administrative Agent and of
      counsel to each of the other Agents and Lenders.

                  7.4(b) The Borrower agrees to pay, and to save the Agents and
      the Lenders harmless from, any and all liabilities with respect to, or
      resulting from any delay in paying, any and all stamp, excise, sales or
      other taxes which may be payable or determined to be payable with respect
      to any of the Collateral or in connection with any of the transactions
      contemplated by this Agreement.


                                       22
<PAGE>

                  7.4(c) The Borrower agrees to pay, and to save the Agents and
      the Lenders harmless from, any and all liabilities, obligations, losses,
      damages, penalties, actions, judgments, suits, costs, expenses or
      disbursements of any kind or nature whatsoever with respect to the
      execution, delivery, enforcement, performance and administration of this
      Agreement to the extent the Borrower would be required to do so pursuant
      to subsection 10.5 of the Credit Agreement.

                  7.4(d) The agreements in this subsection 7.4 shall survive
      repayment of the Obligations and all other amounts payable under the
      Credit Agreement and the other Credit Documents.

            7.5 Successors and Assigns. This Agreement shall be binding upon the
successors and assigns of the Borrower and shall inure to the benefit of the
Agents and the Lenders and their successors and assigns; provided that the
Borrower may not assign, transfer or delegate any of its rights or obligations
under this Agreement without the prior written consent of the Administrative
Agent.

            7.6 Set-Off. The Borrower hereby irrevocably authorizes each of the
Agents and Lenders at any time and from time to time pursuant to subsection
10.7(a) of the Credit Agreement shall have occurred and be continuing, without
notice to the Borrower, any such notice being expressly waived by the Borrower,
to set-off and appropriate and apply any and all deposits (general or special,
time or demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Agent or Lender to or for the credit or the account of the
Borrower, or any part thereof in such amounts as such Agent or Lender may elect,
against and on account of the obligations and liabilities of the Borrower to
such Agent or Lender hereunder and claims of every nature and description of
such Agent or Lender against the Borrower, in any currency, whether arising
hereunder, under the Credit Agreement, any other Credit Document or otherwise,
as such Agent or Lender may elect, whether or not any Agent or Lender has made
any demand for payment and although such obligations, liabilities and claims may
be contingent or unmatured. Each of the Agents and Lenders shall notify the
Borrower promptly of any such set-off and the application made by such Agent or
Lender of the proceeds thereof, provided that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of the
Agent and Lender under this subsection 7.6 are in addition to other rights and
remedies (including, without limitation, other rights of set-off) which such
Agent or Lender may have.

            7.7 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            7.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            7.9 Section Headings. The Section headings used in this Agreement
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

      the Administrative Agent, for the ratable benefit of the Agents and the
      Lenders, as collateral security for the Obligations, enforceable in
      accordance with the terms hereof against all creditors of such Grantor and
      any Persons purporting to purchase any Collateral from such Grantor,

      validly issued and are fully paid and nonassessable.

                  3.7(c) Each of the Pledged Notes constitutes the legal, valid
      and binding obligation of the obligor with respect thereto, enforceable in
      accordance with its terms, subject to the effects of bankruptcy,
      insolvency, fraudulent conveyance, reorganization, moratorium and other
      similar laws relating to or affecting creditors' rights generally, general
      equitable principles (whether considered in a proceeding in equity or at
      law) and an implied covenant of good faith and fair dealing.

Grantor shall take, or shall refrain from taking, as the case may be, each

      from time to time reasonably request.

            4.4 Payment of Obligations. Such Grantor will pay and discharge or
otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all material taxes, assessments and governmental charges or levies
imposed upon the Collateral or in respect of income or profits therefrom, as
well as all material claims of any kind (including, without limitation, claims
for labor, materials and supplies) against or with respect to the Collateral,
except that no such charge need be paid if the amount or validity thereof is
currently being contested in good faith by appropriate proceedings, reserves in
conformity with GAAP with respect thereto have been provided on the books of

      from time to time statements and schedules further identifying and

      Collateral as the Administrative Agent may reasonably request, all in
      reasonable detail.

                  4.5(c) At any time and from time to time, upon the written
      request of the Administrative Agent, and at the sole expense of such
      Grantor, such Grantor will promptly and duly execute and deliver, and have
      recorded, such further instruments and documents and take such further
      actions as the Administrative Agent may reasonably request for the purpose
      of obtaining or preserving the full benefits of this Agreement and of the
      rights and powers herein granted, including, without limitation, the

      in connection with this Agreement would become misleading.

            4.7 Notices. Such Grantor will advise the Agents and the Lenders
promptly, in reasonable detail, of:

                  4.7(a) any Lien (other than security interests created hereby
      or Liens permitted under the Credit Agreement) on any of the Collateral
      which would adversely affect the ability of the Administrative Agent to
      exercise any of its remedies hereunder; and

                  4.7(b) of the occurrence of any other event of which it is
      aware which could reasonably be expected to have a material adverse effect
      on the enforceability, or perfection or priority of, the security

      to, in substitution of, as a conversion of, or in exchange for, any shares
      of the Pledged Stock, or otherwise in respect thereof, such Grantor shall
      accept the same as the agent of the Agents and the Lenders, hold the same
      in trust for the Agents and the Lenders and deliver the same forthwith to
      the Administrative Agent in the exact form received, duly indorsed by such
      Grantor to the Administrative Agent, if required, together with an undated

      Grantor and with, if the Administrative Agent so requests, signature
      guaranteed, to be held by the Administrative Agent, subject to the terms
      hereof, as additional collateral security for the Obligations. Any sums
      paid upon or in respect of the Pledged Securities upon the liquidation or
      dissolution of any Issuer shall be paid over to the Administrative Agent
      to be held by it hereunder as additional collateral security for the
      Obligations, and in case any distribution of capital shall be made on or

      Credit Agreement, if any sums of money or property so paid or distributed
      in respect of the Pledged Securities under circumstances described in this
      Section 4.8(a) shall be received by such Grantor, such Grantor shall,
      until such money or property is paid or delivered to the


                                       11
<PAGE>

      Administrative Agent, hold such money or property in trust for the
      Lenders, segregated from other funds of such Grantor, as additional
      collateral security for the Obligations.

                  4.8(b) Except as provided in the Credit Agreement, without the
      prior written consent of the Administrative Agent, such Grantor will not
      (i) vote to enable, or take any other action to permit, any Issuer to
      issue any stock or other equity securities of any nature or to issue any
      other securities convertible into or granting the right to purchase or
      exchange for any stock or other equity securities of any nature of any
      Issuer, (ii) sell, assign, transfer, exchange, or otherwise dispose of, or
      grant any option with respect to, the Pledged Securities or Proceeds
      thereof (except pursuant to a transaction expressly permitted by the
      Credit Agreement), (iii) create, incur or permit to exist any Lien or
      option in favor of, or any claim of any Person with respect to, any of the

      any agreement or undertaking restricting the right or ability of such
      Grantor or the Administrative Agent to sell, assign or transfer any of the
      Pledged Securities or Proceeds thereof.

                  4.8(c) In the case of each Grantor which is an Issuer, such
      Issuer agrees that (i) it will be bound by the terms of this Agreement
      relating to the Pledged Securities issued by it and will comply with such
      terms insofar as such terms are applicable to it, (ii) it will notify the
      Administrative Agent promptly in writing of the occurrence of any of the
      events described in subsection 5.8(a) with respect to the Pledged
      Securities issued by it and (iii) the terms of subsections 6.3(c) and 6.7

                  4.9(c) Upon the written request of the Required Lenders upon
      the occurrence and during the continuance of an Event of Default, each

      of Claims Act of 1940, as amended, and each Grantor shall, upon written
      request of the Administrative Agent, promptly use its best efforts to have
      such Notices of Assignment


                                       12

      Government Authority; (iv) with respect to each contract, agreement or
      transaction pursuant to which any State or any political subdivision
      thereof is a party, execute and deliver all notices which are required
      under, and comply in all other respects with, the laws of such State to

                  4.10(b) Such Grantor will not amend, modify, terminate or
      waive any provision of any material Contract in any manner which could
      reasonably be expected to materially adversely affect the value of such

      a copy of each material demand, notice or document received by it relating

      to obtain such Government Contract and gives the Administrative Agent
      written notice that it has entered into such Restricted Government
      Contract.

      (i) continue to use each material Trademark on each and every trademark
      class of goods applicable to its current line as reflected in its current
      catalogs, brochures and price lists in order to maintain such Trademark in

      the quality of products and services offered under such material
      Trademark, (iii) use such material Trademark with the appropriate notice
      of registration and all other notices and legends required by applicable

      not do any act or knowingly omit to do any act whereby such material
      Trademark may become invalidated or impaired in any way, and (vi) use

                  4.11(b) Such Grantor will not do any act, or omit to do any
      act, whereby any material Patent may become forfeited, abandoned or
      dedicated to the public and will use reasonable efforts to prevent any
      sublicensee from doing any act, or omitting to do any act, whereby any
      material Patent may become forfeited, abandoned or dedicated to the
      public.

                  4.11(c) Such Grantor will not do any act or knowingly omit to
      do any act and will use reasonable efforts to prevent any licensee or
      sublicensee thereof from doing any act or knowingly omitting to do any act

      will use reasonable efforts to prevent any sublicensee from doing any act

                  4.11(e) Such Grantor will notify the Administrative Agent and
      the Lenders immediately if it knows that any application or registration

      institution of, or any such determination or development in, any
      proceeding in the United States Patent and Trademark Office, the United
      States Copyright Office or any court or tribunal in any country) regarding
      such Grantor's ownership of, or the validity of, any material Intellectual
      Property or such Grantor's right to register the same or to own and
      maintain the same.

                  4.11(f) Whenever such Grantor, either by itself or through
      any agent, employee, licensee or designee, shall file an application for

      agreements, instruments, documents, and papers as the Administrative Agent
      may reasonably request to evidence the Agents' and the Lenders' security
      interest in any Copyright, Patent or Trademark and the goodwill and
      general intangibles of such Grantor relating thereto or represented
      thereby.

                  4.11(g) Such Grantor will take all reasonable and necessary

      obtain the relevant registration) and to maintain each registration of the
      material Intellectual Property, including, without limitation, filing of
      any necessary applications for renewal, affidavits of use and affidavits
      of incontestability and paying all necessary fees, except to the extent
      the failure to do so could not, individually or in the aggregate, be
      expected to have a Material Adverse Effect.

                  4.11(h) In the event that any material Intellectual Property
      is infringed, misappropriated or diluted by a third party, such Grantor
      shall (i) take such actions as such Grantor shall reasonably deem
      appropriate under the circumstances to protect such Intellectual Property
      and (ii) if such Intellectual Property is of material economic value to
      the Borrower and its Subsidiaries taken as a whole, promptly notify the
      Administrative Agent after it learns thereof and sue for infringement,
      misappropriation or dilution, seek injunctive relief where appropriate and
      recover any and all damages for such infringement, misappropriation or
      dilution. 

                         SECTION 5. REMEDIAL PROVISIONS

            5.1 Certain Matters Relating to Receivables.

                  5.1(a) The Administrative Agent shall have the right to make
      test verifications of the Receivables in any manner and through any medium
      that it reasonably considers advisable, and each Grantor shall furnish all
      such assistance and information as the Administrative Agent may require in
      connection with such test verifications. At any time and from time to
      time, upon the Administrative Agent's request and at the expense of the
      relevant Grantor, such Grantor shall cause independent public accountants
      or others satisfactory to the Administrative Agent to furnish to the
      Administrative Agent reports showing reconciliations, aging and test
      verifications of, and trial balances for, the Receivables.

                  5.1(b) The Administrative Agent hereby authorizes each Grantor
      to collect such Grantor's Receivables, subject to the Administrative
      Agent's direction and control, and the Administrative Agent may curtail or
      terminate said authority at any time after the occurrence and during the
      continuance of an Event of Default. If required by the Administrative
      Agent at any time after the occurrence and during the continuance of an
      Event of Default, any payments of Receivables, when collected by any
      Grantor, (i) shall be forthwith (and, in any event, within two Business
      Days) deposited by such Grantor in the exact form received, duly indorsed
      by such Grantor to the Administrative Agent if required, in a Collateral
      Account maintained under the sole dominion and control of the
      Administrative Agent, subject to withdrawal by the Administrative Agent
      for the account of the Lenders only as provided in subsection 5.5, and
      (ii) until so turned over, shall be held by such Grantor in trust for the
      Agents and the Lenders, segregated from other


                                       15
<PAGE>

      funds of such Grantor. Each such deposit of Proceeds of Receivables shall
      be accompanied by a report identifying in reasonable detail the nature and
      source of the payments included in the deposit. In addition, the
      Administrative Agent shall have the right at any time, upon the occurrence
      and during the continuance of an Event of Default and upon written notice
      to such Grantor of its intention to do so, to require the Grantor to
      prepare notices of assignment for each Government Contract for which it
      has not previously delivered a notice of assignment pursuant to Section
      6.13 of the Credit Agreement and to file such notices of assignment (and
      any notice of assignment delivered to the Administrative Agent pursuant to
      Section 6.13 of the Credit Agreement) with the appropriate contracting
      officer of the appropriate Government Authority and to otherwise notify
      the account debtors or obligors under any Receivables of the assignment of
      such Receivables to the Administrative Agent and to direct such account
      debtors or obligors to make payment of all amounts due or to become due to
      the Grantor thereunder directly to the Administrative Agent and, upon such
      notification and at the expense of the Grantor, to enforce collection of
      any such Receivables, and to adjust, settle or compromise the amount or
      payment thereof, in the same manner and to the same extent as the Grantor
      might have done. After receipt by the Grantor of the notice from the
      Administrative Agent referred to in the proviso to the preceding sentence,
      (i) all amounts and proceeds (including instruments) received by the
      Grantor in respect of the Receivables shall be received in trust for the
      benefit of the Administrative Agent, the Agents, the Lenders, the Issuing
      Banks and the other Holders hereunder, shall be segregated from other
      funds of the Grantor and shall be forthwith paid over to the
      Administrative Agent in the same form as so received (with any necessary
      indorsement) to be applied to the Obligations in accordance with Section 8
      of the Credit Agreement and (ii) the Grantor shall not adjust, settle or
      compromise the amount or payment of any Account, release wholly or partly
      any account debtor or obligor thereof, or allow any credit or discount
      thereon.

                  5.1(c) At the Administrative Agent's request, each Grantor
      shall deliver to the Administrative Agent all original and other documents
      evidencing, and relating to, the agreements and transactions which gave
      rise to the Receivables, including, without limitation, all original
      orders, invoices and shipping receipts.

            5.2 Communications with Obligors; Grantors Remain Liable.

                  5.2(a) The Administrative Agent in its own name or in the name
      of others may at any time after the occurrence and during the continuance
      of an Event of Default communicate with obligors under the Receivables and
      parties to the Contracts to verify with them to the Administrative Agent's
      satisfaction the existence, amount and terms of any Receivables or
      Contracts.

                  5.2(b) Upon the request of the Administrative Agent at any
      time after the occurrence and during the continuance of an Event of
      Default, each Grantor shall notify obligors on the Receivables and parties
      to the Contracts that the Receivables and the Contracts have been assigned
      to the Administrative Agent for the ratable benefit of the Lenders and
      that payments in respect thereof shall be made directly to the
      Administrative Agent.

                  5.2(c) Anything herein to the contrary notwithstanding, each
      Grantor shall remain liable under each of the Receivables and Contracts to
      observe and perform all the conditions and obligations to be observed and
      performed by it thereunder, all in accordance with


                                       16
<PAGE>

      the terms of any agreement giving rise thereto. Neither the Administrative
      Agent nor any Lender shall have any obligation or liability under any
      Receivable (or any agreement giving rise thereto) or Contract by reason of
      or arising out of this Agreement or the receipt by any Agent or Lender of
      any payment relating thereto, nor shall any Agent or Lender be obligated
      in any manner to perform any of the obligations of any Grantor under or
      pursuant to any Receivable (or any agreement giving rise thereto) or
      Contract, to make any payment, to make any inquiry as to the nature or the
      sufficiency of any payment received by it or as to the sufficiency of any
      performance by any party thereunder, to present or file any claim, to take
      any action to enforce any performance or to collect the payment of any
      amounts which may have been assigned to it or to which it may be entitled
      at any time or times.

            5.3 Pledged Stock.

                  5.3(a) Unless an Event of Default shall have occurred and be
      continuing and the Administrative Agent shall have given notice to the
      relevant Grantor of the Administrative Agent's intent to exercise its
      corresponding rights pursuant to subsection 5.3(b), each Grantor shall be
      permitted to receive all cash dividends paid in respect of the Pledged
      Stock and all payments made in respect of the Pledged Notes, in each case
      paid in the normal course of business of the relevant Issuer and
      consistent with past practice, to the extent permitted in the Credit
      Agreement, and to exercise all voting and corporate rights with respect to
      the Pledged Securities; provided, however, that no vote shall be cast or
      corporate right exercised or other action taken which, in the
      Administrative Agent's reasonable judgment, would materially impair the
      Collateral or which would result in any violation of any provision of the
      Credit Agreement, this Agreement or any other Credit Document.

                  5.3(b) If an Event of Default shall occur and be continuing
      and the Administrative Agent shall give notice of its intent to exercise
      such rights to the relevant Grantor or Grantors, (i) the Administrative
      Agent shall have the right to receive any and all cash dividends, payments
      or other Proceeds paid in respect of the Pledged Securities and make
      application thereof to the Obligations in such order as the Administrative
      Agent may determine, and (ii) any or all of the Pledged Securities shall
      be registered in the name of the Administrative Agent or its nominee, and
      the Administrative Agent or its nominee may thereafter exercise (x) all
      voting, corporate and other rights pertaining to such Pledged Securities
      at any meeting of shareholders of the relevant Issuer or Issuers or
      otherwise and (y) any and all rights of conversion, exchange and
      subscription and any other rights, privileges or options pertaining to
      such Pledged Securities as if it were the absolute owner thereof
      (including, without limitation, the right to exchange at its discretion
      any and all of the Pledged Securities upon the merger, consolidation,
      reorganization, recapitalization or other fundamental change in the
      corporate structure of any Issuer, or upon the exercise by any Grantor or
      the Administrative Agent of any right, privilege or option pertaining to
      such Pledged Securities, and in connection therewith, the right to deposit
      and deliver any and all of the Pledged Securities with any committee,
      depositary, transfer agent, registrar or other designated agency upon such
      terms and conditions as the Administrative Agent may determine), all
      without liability except to account for property actually received by it,
      but the Administrative Agent shall have no duty to any Grantor to exercise
      any such right, privilege or option and shall not be responsible for any
      failure to do so or delay in so doing.


                                       17
<PAGE>

                  5.3(c) Each Grantor hereby authorizes and instructs each
      Issuer of any Pledged Securities pledged by such Grantor hereunder to (i)
      comply with any instruction received by it from the Administrative Agent
      in writing that (x) states that an Event of Default has occurred and is
      continuing and (y) is otherwise in accordance with the terms of this
      Agreement, without any other or further instructions from such Grantor,
      and each Grantor agrees that each Issuer shall be fully protected in so
      complying, and (ii) unless otherwise expressly permitted hereby, pay any
      dividends or other payments with respect to the Pledged Securities
      directly to the Administrative Agent.

            5.4 Proceeds to be Turned Over To Administrative Agent. In addition
to the rights of the Agent and the Lenders specified in subsection 5.1 with
respect to payments of Receivables, if an Event of Default shall occur and be
continuing, all Proceeds received by any Grantor consisting of cash, checks and
other near-cash items shall be held by such Grantor in trust for the Agents and
the Lenders, segregated from other funds of such Grantor, and shall, forthwith
upon receipt by such Grantor, be turned over to the Administrative Agent in the
exact form received by such Grantor (duly indorsed by such Grantor to the
Administrative Agent, if required). All Proceeds received by the Administrative
Agent hereunder shall be held by the Administrative Agent in a Collateral
Account maintained under its sole dominion and control. All Proceeds while
held by the Administrative Agent in a Collateral Account (or by such Grantor in
trust for the Administrative Agent and the Lenders) shall continue to be held as
collateral security for all the Obligations and shall not constitute payment
thereof until applied as provided in subsection 5.5.

            5.5 Application of Proceeds. At such intervals as may be agreed upon
by the Borrower and the Administrative Agent, or, if an Event of Default shall
have occurred and be continuing, at any time at the Administrative Agent's
election, the Administrative Agent may apply all or any part of Proceeds held in
any Collateral Account in payment of the Obligations in such order as required
by the Credit Agreement, and any part of such funds which are not required as
collateral security for the Obligations shall be paid over from time to time by
the Administrative Agent to the Borrower or to whomsoever may be lawfully
entitled to receive the same. Any balance of such Proceeds remaining after the
Obligations shall have been paid in full, no Letters of Credit shall be
outstanding and the Commitments shall have terminated shall be paid over to the
Borrower or to whomsoever may be lawfully entitled to receive the same.

            5.6 Code and Other Remedies. If an Event of Default shall occur and
be continuing, the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted to them in this Agreement
and in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the New York UCC
or any other applicable law. Without limiting the generality of the foregoing,
the Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of any of the Agents or Lenders or elsewhere
upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption
of any credit risk. Any Agents or


                                       18
<PAGE>

Lenders shall have the right upon any such public sale or sales, and, to the
extent permitted by law, upon any such private sale or sales, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of
redemption in any Grantor, which right or equity is hereby waived and released.
Each Grantor further agrees, at the Administrative Agent's request, to assemble
the Collateral and make it available to the Administrative Agent at places which
the Administrative Agent shall reasonably select, whether at such Grantor's
premises or elsewhere. The Administrative Agent shall apply the net proceeds of
any action taken by it pursuant to this subsection 5.6, after deducting all
reasonable costs and expenses of every kind incurred in connection therewith or
incidental to the care or safekeeping of any of the Collateral or in any way
relating to the Collateral or the rights of the Agents and the Lenders
hereunder, including, without limitation, reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Obligations, in such
order as the Administrative Agent may elect, and only after such application and
after the payment by the Administrative Agent of any other amount required by
any provision of law, including, without limitation, Section 9-504(1)(c) of the
New York UCC, need the Administrative Agent account for the surplus, if any, to
any Grantor. To the extent permitted by applicable law, each Grantor waives all
claims, damages and demands it may acquire against any Agents or Lenders arising
out of the exercise by them of any rights hereunder. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least 15 days before such sale
or other disposition.

            5.7 Registration Rights.

                  5.7(a) If the Administrative Agent shall determine to exercise
      its right to sell any or all of the Pledged Stock pursuant to subsection
      5.6, and if in the opinion of the Administrative Agent it is necessary or
      advisable to have the Pledged Stock, or that portion thereof to be sold,
      registered under the provisions of the Securities Act, the relevant
      Grantor will cause the Issuer thereof to (i) execute and deliver, and
      cause the directors and officers of such Issuer to execute and deliver,
      all such instruments and documents, and do or cause to be done all such
      other acts as may be, in the opinion of the Administrative Agent,
      necessary or advisable to register the Pledged Stock, or that portion
      thereof to be sold, under the provisions of the Securities Act, (ii) use
      its commercially reasonable efforts to cause the registration statement
      relating thereto to become effective and to remain effective for a period
      of one year from the date of the first public offering of the Pledged
      Stock, or that portion thereof to be sold, and (iii) make all amendments
      thereto and/or to the related prospectus which, in the opinion of the
      Administrative Agent, are necessary or advisable, all in conformity with
      the requirements of the Securities Act and the rules and regulations of
      the Securities and Exchange Commission applicable thereto. Each Grantor
      agrees to cause such Issuer to comply with the provisions of the
      securities or "Blue Sky" laws of any and all jurisdictions which the
      Administrative Agent shall designate and to make available to its security
      holders, as soon as practicable, an earnings statement (which need not be
      audited) which will satisfy the provisions of Section 11(a) of the
      Securities Act.

                  5.7(b) Each Grantor recognizes that the Administrative Agent
      may be unable to effect a public sale of any or all the Pledged Stock, by
      reason of certain prohibitions contained in the Securities Act and
      applicable state securities laws or otherwise, and may be compelled to
      resort to one or more private sales thereof to a restricted group of
      purchasers which will be obliged to agree, among other things, to acquire
      such securities for their own account for investment and not with a view
      to the distribution or resale thereof. Each Grantor acknowledges and
      agrees that any such private sale may result in prices and other terms
      less favorable than if


                                       19
<PAGE>

      such sale were a public sale and, notwithstanding such circumstances,
      agrees that any such private sale shall be deemed to have been made in a
      commercially reasonable manner. The Administrative Agent shall be under no
      obligation to delay a sale of any of the Pledged Stock for the period of
      time necessary to permit the Issuer thereof to register such securities
      for public sale under the Securities Act, or under applicable state
      securities laws, even if such Issuer would agree to do so.

                  5.7(c) Each Grantor agrees to use its commercially reasonable
      efforts to do or cause to be done all such other acts as may be necessary
      to make such sale or sales of all or any portion of the Pledged Stock
      pursuant to this subsection 5.7 valid and binding and in compliance with
      any and all other applicable Requirements of Law. Each Grantor further
      agrees that a breach of any of the covenants contained in this subsection
      5.7 will cause irreparable injury to the Agents and the Lenders, that the
      Agents and the Lenders have no adequate remedy at law in respect of such
      breach and, as a consequence, that each and every covenant contained in
      this subsection 5.7 shall be specifically enforceable against such
      Grantor, and such Grantor hereby waives and agrees not to assert any
      defenses against an action for specific performance of such covenants
      except for a defense that no Event of Default has occurred under the
      Credit Agreement.

            5.8 Waiver; Deficiency. Each Grantor waives and agrees not to assert
any rights or privileges which it may acquire under Section 9-112 of the New
York UCC. Each Grantor shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Administrative Agent or any Lender to collect such deficiency.

                       SECTION 6. THE ADMINISTRATIVE AGENT

            6.1 Administrative Agent's Appointment as Attorney-in-Fact, etc.

                  6.1(a) Each Grantor hereby irrevocably constitutes and
      appoints the Administrative Agent and any officer or agent thereof, with
      full power of substitution, as its true and lawful attorney-in-fact with
      full irrevocable power and authority in the place and stead of such
      Grantor and in the name of such Grantor or in its own name, for the
      purpose of carrying out the terms of this Agreement, to take any and all
      appropriate action and to execute any and all documents and instruments
      which may be necessary or desirable to accomplish the purposes of this
      Agreement, and, without limiting the generality of the foregoing, each
      Grantor hereby gives the Administrative Agent the power and right, on
      behalf of such Grantor, without notice to or assent by such Grantor, to do
      any or all of the following:

                        (i) in the name of such Grantor or its own name, or
            otherwise, take possession of and indorse and collect any checks,
            drafts, notes, acceptances or other instruments for the payment of
            moneys due under any Receivable or Contract or with respect to any
            other Collateral and file any claim or take any other action or
            proceeding in any court of law or equity or otherwise deemed
            appropriate by the Administrative Agent for the purpose of
            collecting any and all such moneys due under any Receivable or
            Contract or with respect to any other Collateral whenever payable;


                                       20
<PAGE>

                        (ii) in the case of any Intellectual Property, execute
            and deliver, and have recorded, any and all agreements, instruments,
            documents and papers as the Administrative Agent may request to
            evidence the Agents' and the Lenders' security interest in such
            Intellectual Property and the goodwill and general intangibles of
            such Grantor relating thereto or represented thereby;

                        (iii) pay or discharge taxes and Liens levied or placed
            on or threatened against the Collateral, effect any repairs or any
            insurance called for by the terms of this Agreement and pay all or
            any part of the premiums therefor and the costs thereof;

                        (iv) execute, in connection with any sale provided for
            in subsection 5.6 or 5.7, any endorsements, assignments or other
            instruments of conveyance or transfer with respect to the
            Collateral; and

                        (v)(A) direct any party liable for any payment under any
            of the Collateral to make payment of any and all moneys due or to
            become due thereunder directly to the Administrative Agent or as the
            Administrative Agent shall direct; (B) ask or demand for, collect,
            and receive payment of and receipt for, any and all moneys, claims
            and other amounts due or to become due at any time in respect of or
            arising out of any Collateral; (C) sign and indorse any invoices,
            freight or express bills, bills of lading, storage or warehouse
            receipts, drafts against debtors, assignments, verifications,
            notices and other documents in connection with any of the
            Collateral; (D) commence and prosecute any suits, actions or
            proceedings at law or in equity in any court of competent
            jurisdiction to collect the Collateral or any portion thereof and to
            enforce any other right in respect of any Collateral; (E) defend any
            suit, action or proceeding brought against such Grantor with
            respect to any Collateral; (F) settle, compromise or adjust any such
            suit, action or proceeding and, in connection therewith, give such
            discharges or releases as the Administrative Agent may reasonably
            deem appropriate; (G) assign any Copyright, Patent or Trademark
            (along with the goodwill of the business to which any such
            Copyright, Patent or Trademark pertains), throughout the world for
            such term or terms, on such conditions, and in such manner, as the
            Administrative Agent shall in its sole discretion determine; and (H)
            generally, sell, transfer, pledge and make any agreement with
            respect to or otherwise deal with any of the Collateral as fully and
            completely as though the Administrative Agent were the absolute
            owner thereof for all purposes, and do, at the Administrative
            Agent's option and such Grantor's expense, at any time, or from time
            to time, all acts and things which the Administrative Agent deems
            necessary to protect, preserve or realize upon the Collateral and
            the Agents' and the Lenders' security interests therein and to
            effect the intent of this Agreement, all as fully and effectively as
            such Grantor might do.

            Anything in this subsection 6.1(a) to the contrary notwithstanding,
the Administrative Agent agrees that it will not exercise any rights under the
power of attorney provided for in this subsection 6.1(a) unless an Event of
Default shall have occurred and be continuing.

                  6.1(b) If any Grantor fails to perform or comply with any of
      its agreements contained herein, the Administrative Agent, at its option,
      but without any obligation so to do, may perform or comply, or otherwise
      cause performance or compliance, with such agreement.


                                       21
<PAGE>

                  6.1(c) The expenses of the Administrative Agent incurred in
      connection with actions undertaken as provided in this subsection 6.1,
      together with interest thereon at a rate per annum equal to the rate per
      annum at which interest would then be payable on past due Base Rate Loans
      under the Credit Agreement, from the date of payment by the Administrative
      Agent to the date reimbursed by the relevant Grantor, shall be payable by
      such Grantor to the Administrative Agent on demand.

                  6.1(d) Each Grantor hereby ratifies all that said attorneys
      shall lawfully do or cause to be done by virtue hereof. All powers,
      authorizations and agencies contained in this Agreement are coupled with
      an interest and are irrevocable until this Agreement is terminated and the
      security interests created hereby are released.

            6.2 Duty of Administrative Agent. The Administrative Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the New York UCC or
otherwise, shall be to deal with it in the same manner as the Administrative
Agent deals with similar property for its own account. Neither the
Administrative Agent, any Lender nor any of their respective officers,
directors, employees or agents shall be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of any Grantor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Agents and the Lenders hereunder are solely to protect the
Administrative Agents' and the Lenders' interests in the Collateral and shall
not impose any duty upon any Agents or Lender to exercise any such powers. The
Agents and the Lenders shall be accountable only for amounts that they actually
receive as a result of the exercise of such powers, and neither they nor any of
their officers, directors, employees or agents shall be responsible to any
Grantor for any act or failure to act hereunder, except for their own gross
negligence or willful misconduct.

            6.3 Execution of Financing Statements. Pursuant to Section 9-402 of
the New York UCC and any other applicable law, each Grantor authorizes the
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with respect to the Collateral without the
signature of such Grantor in such form and in such offices as the Administrative
Agent reasonably determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement. A photographic or other reproduction
of this Agreement shall be sufficient as a financing statement or other filing
or recording document or instrument for filing or recording in any jurisdiction.

            6.4 Authority of Administrative Agent. Each Grantor acknowledges
that the rights and responsibilities of the Administrative Agent under this
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as among the Agents and the
Lenders, be governed by the Credit Agreement and by such other agreements with
respect thereto as may exist from time to time among them, but, as among the
Agents and the Grantors, the Administrative Agent shall be conclusively presumed
to be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and no Grantor shall be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                            SECTION 7. MISCELLANEOUS

or any Grantor hereunder shall be effected in the manner provided for in
subsection 10.2 of the Credit Agreement.

            7.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default. No failure to exercise, nor any delay in
exercising, on the part of any of the Agents or Lenders, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by any of the Agents or Lenders of any right or remedy hereunder on any
one occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent, on behalf of other Agents and the Lenders, would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

            7.4 Enforcement Expenses; Indemnification.

                  7.4(a) Each Grantor agrees to pay or reimburse each of the
      Lenders and the Agents for all its reasonable costs and expenses incurred
      in collecting against such Grantor or otherwise enforcing or preserving
      any rights under this Agreement and the other Credit Documents to which
      such Grantor is a party, including, without limitation, the reasonable
      fees and disbursements of counsel to the Administrative Agent and of
      counsel each of the other Agents and Lenders.

                  7.4(b) Each Grantor agrees to pay, and to save the Agents and
      the Lenders harmless from, any and all liabilities with respect to, or
      resulting from any delay in paying, any and all stamp, excise, sales or
      other taxes which may be payable or determined to be payable with respect
      to any of the Collateral or in connection with any of the transactions
      contemplated by this Agreement.

                  7.4(c) Each Grantor agrees to pay, and to save the Agents and
      the Lenders harmless from, any and all liabilities, obligations, losses,
      damages, penalties, actions, judgments, suits, costs, expenses or
      disbursements of any kind or nature whatsoever with respect to the
      execution, delivery, enforcement, performance and administration of this
      Agreement to the extent the Borrower would be required to do so pursuant
      to subsection 10.5 of the Credit Agreement.

                  7.4(d) The agreements in this subsection 7.4 shall survive
      repayment of the Obligations and all other amounts payable under the
      Credit Agreement and the other Credit Documents.

            7.5 Successors and Assigns. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of the
Agents and the Lenders and their

<PAGE>

successors and assigns; provided that no Grantor may assign, transfer or
delegate any of its rights or obligations under this Agreement without the
prior written consent of the Administrative Agent.

            7.6 Set-Off. Each Grantor hereby irrevocably authorizes each of the
Agents and Lenders at any time and from time to time pursuant to subsection
10.7(a) of the Credit Agreement shall have occurred and be continuing, without
notice to such Grantor or any other Grantor, any such notice being expressly
waived by each Grantor; to set-off and appropriate and apply any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by Agent or Lender to or for the credit or
the account of such Grantor, or any part thereof in such amounts as such Agent
or Lender may elect, against and on account of the obligations and liabilities
of such Grantor to such Agent or Lender hereunder and claims of every nature and
description of such Agent or Lender against such Grantor, in any currency,
whether arising hereunder, under the Credit Agreement, any other Credit Document
or otherwise, as such Agent or Lender may elect, whether or not any Agent or
Lender has made any demand for payment and although such obligations,
liabilities and claims may be contingent or unmatured. Each of the Agents and
Lenders shall notify such Grantor promptly of any such set-off and the
application made by such Agent or Lender of the proceeds thereof, provided that
the failure to give such notice shall not affect the validity of such set-off
and application. The rights of each Agent and Lender under this subsection 7.6
are in addition to other rights and remedies (including, without limitation,
other rights of set-off) which such Agent or Lender may have.

            7.7 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            7.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            7.9 Section Headings. The Section headings used in this Agreement
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            7.10 Integration. This Agreement and the other Credit Documents
represent the agreement of the Grantors, the Agents and the Lenders with respect
to the subject matter hereof and thereof, and there are no promises,
undertakings, representations or warranties by any of the Agents or Lenders
relative to subject matter hereof and thereof not expressly set forth or
referred to herein or in the other Credit Documents.

CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

<PAGE>

pursuant to plans and specifications approved by Mortgagee, in its reasonable
discretion, within ninety (90) days from the date of such condemnation, damage
or destruction, and shall complete the same with reasonable diligence and as
promptly as may be practicable after Mortgagee approves the plans and
specifications. Any Loss Proceeds received in connection with such condemnation,
damage or destruction shall be payable to Mortgagee to be applied in accordance
with the following provisions:

            (i) If the Loss Proceeds received are less than $50,000, then such
proceeds shall be given to Mortgagor to be held in trust for Mortgagee and the
Lenders and applied only for the purpose of repairing, restoring, replacing or
rebuilding the Mortgaged Property. Any excess held by Mortgagor, after such
restoration, may be retained by Mortgagor.

            (ii) In all other cases, the net amount of the Loss Proceeds on
account of such condemnation, damage or destruction to the Mortgaged Property,
after reimbursement out of such proceeds for any costs and expenses (including
reasonable attorneys' fees and disbursements) for collection thereof (such net
proceeds and deposits, and any other deposits made therein as provided below,
being herein collectively called the "Fund") shall be received and held by
Mortgagee and applied in accordance with the following provisions:

                  (A) If the net amount of Loss Proceeds shall be insufficient
to pay the entire cost of restoring the Mortgaged Property (as estimated by a
registered architect or professional engineer reasonably satisfactory to
Mortgagee, which estimate shall be delivered to Mortgagee before the
commencement of any such work), Mortgagor shall, prior to allowing such work to
commence, deposit the amount of the deficiency into the Fund, and thereafter
from time to time such additional amounts as shall be needed to meet any
increases in estimates made by said registered architect or professional
engineer. If the net amount of said proceeds shall be insufficient to pay the
entire cost of such work, Mortgagor shall pay and be responsible for the
deficiency.

                  (B) Mortgagor shall be entitled out of the Fund to ninety
percent (90%) of the cost of making temporary repairs or doing other work to
protect the Mortgaged Property pending adjustment of the insurance loss or the
making of permanent repairs, restoration, replacements or rebuilding.

                  (C) Mortgagor shall be entitled out of the Fund to payments
from time to time as the work progresses in amounts equal to a maximum of ninety
percent (90%) of the cost of labor and material incorporated into and used in
such work and architects' and engineers' fees, provided and upon condition that
(1) the work shall have been done in accordance with the plans and
specifications therefor, any other requirements contained in this Section, (2)
the remaining amount of the Fund shall be sufficient to pay in full for all of
the remaining work, and (3) a certificate of an independent registered architect
or professional engineer satisfactory to Mortgagee stating that such conditions
have been met shall have been delivered to Mortgagee.

                  (D) Mortgagor shall be entitled out of the Fund to the
remaining ten percent (10%) of the cost of labor and material incorporated into
and used in such work and architects' and engineers' fees when such work shall
have been fully completed and paid for and a certificate of an independent
registered architect or professional engineer satisfactory to Mortgagee stating
that such conditions have been met shall have been delivered to Mortgagee.

                  (E) At Mortgagee's request, Mortgagor shall furnish to
Mortgagee at the time of any such progress or final payment, a title search or
other evidence reasonably satisfactory to


                                        6
<PAGE>

Mortgagee (including waivers of lien agreements from the general contractor
supervising such work, or in the absence of a general contractor, all
contractors, materialmen and others providing labor or services in connection
therewith) that the Mortgaged Property and the interests therein of Mortgagee
and Mortgagor shall be free from (1) liens for labor performed or claimed to
have been performed or materials supplied or claimed to have been supplied,
unless the same are bonded, and (2) chattel mortgages, conditional sales
contacts, title retention agreements, security interests and agreements,
financing agreements, financing statements and any similar agreements, in
connection with such work. Notwithstanding any provision to the contrary,
Mortgagor shall not be entitled to any amount out of the Fund (x) while any such
lien or other encumbrance shall remain unsatisfied of record, unless in the case
of a lien the same is bonded or (y) during the continuance of any Event of
Default.

                  (F) If any of such Loss Proceeds shall remain after the full
completion of, and payment for, such repairs, restoration, replacements or
rebuilding, the excess shall be paid to Mortgagor.

            1.9 Inspection. Mortgagee and any persons authorized by Mortgagee

reasonable times upon reasonable notice.

system and protective services charges which are furnished to the Mortgaged
Property, whether public or private.

            1.11 Action by Mortgagee to Preserve Mortgaged Property. Should
Mortgagor fail to make any payment or do any act as and in the manner provided
in this Mortgage, Mortgagee without obligation so to do and without notice to or
demand upon Mortgagor and without releasing Mortgagor from any obligation, may
make or do the same in such manner and to such extent as it may deem necessary
therefor. Mortgagor shall, upon demand therefor by Mortgagee pay all reasonable
costs and expenses incurred by Mortgagee in connection with the exercise by
Mortgagee of the foregoing rights (including, without limitation, reasonable
attorneys' fees and expenses) together with interest thereon from the date of
each such expenditure until paid, calculated at the Default Rate and the same
shall be deemed part of the indebtedness secured by this Mortgage.

            SECTION 2. DEFAULT

            2.1 Remedies. (a) Upon the occurrence of any Event of Default, in
addition to any other rights and remedies Mortgagee may have pursuant to the
Credit Documents, or as provided by law, and without limitation, (a) if such
event is an Event of Default specified in clause (a) or (b) of Section 8 of the
Credit Agreement, automatically the indebtedness secured hereby and all other
amounts owing under this Mortgage and the other Credit Documents immediately
shall become due and payable, and (b) if such event is any other Event of
Default, by `notice to Mortgagor, Mortgagee may declare the indebtedness secured
hereby and all other amounts payable under this Mortgage and the other Credit
Documents to be immediately due and payable. Except as expressly provided above
in this Section, presentment, demand, protest and all other notices of any kind
are hereby expressly waived. In addition, upon the occurrence of any Event of
Default, Mortgagee may immediately take such action, without notice or demand,
as it deems advisable to protect and enforce its rights against Mortgagor and in
and to the Mortgaged Property, including, without limitation, the following
actions, each of which may be pursued concurrently or otherwise, at such time
and in such manner as Mortgagee may determine, in its sole discretion, without
impairing or otherwise affecting the other rights and remedies of Mortgagee:


                                        7
<PAGE>

            (i) Mortgagee may, to the extent permitted by applicable law, (A)
      institute and maintain an action of mortgage foreclosure against all or
      any part of the Mortgaged Property, (B) institute and maintain an action
      on the Notes, or (C) take such other action at law or in equity for the
      enforcement of this Mortgage or any of the Credit Documents as the law may
      allow. Mortgagee may proceed in any such action to final judgment and
      execution thereon for all sums due hereunder, together with interest
      thereon at the Default Rate and all costs of suit, including, without
      limitation, reasonable attorneys' fees and disbursements. Interest at the
      Default Rate shall be due on any judgment obtained by Mortgagee from the
      date of judgment until actual payment is made of the full amount of the
      judgment.

            (ii) Mortgagee may personally, or by its agents, attorneys and
      employees and without regard to the adequacy or inadequacy of the
      Mortgaged Property or any other collateral as security for the
      indebtedness and obligations secured hereby enter into and upon the
      Mortgaged Property and each and every part thereof and exclude Mortgagor
      and its agents and employees therefrom without liability for trespass,
      damage or otherwise (Mortgagor hereby agreeing to surrender possession of
      the Mortgaged Property to Mortgagee upon demand at any such time) and use,
      operate, manage, maintain and control the Mortgaged Property and every
      part thereof. Following such entry and taking of possession, Mortgagee
      shall be entitled, without limitation, (x) to lease all or any part or
      parts of the Mortgaged Property for such periods of time and upon such
      conditions as Mortgagee may, in its discretion, deem proper, (y) to
      enforce, cancel or modify any Lease and (z) generally to execute, do and
      perform any other act, deed, matter or thing concerning the Mortgaged
      Property as Mortgagee shall deem appropriate as fully as Mortgagor might
      do.

            (b) The holder of this Mortgage, in any action to foreclose it,
shall be entitled to the appointment of a receiver. In case of a foreclosure
sale, the Mortgaged Property may be sold, at Mortgagee's election, in one parcel
or in more than one parcel and Mortgagee is specifically empowered, (without
being required to do so, and in its sole and absolute discretion) to cause
successive sales of portions of the Mortgaged Property to be held.

            (c) In the event of any breach of any of the covenants, agreements,
terms or conditions contained in this Mortgage, and notwithstanding to the
contrary any exculpatory or non-recourse language which may be contained herein,
Mortgagee shall be entitled to enjoin such breach and obtain specific
performance of any covenant, agreement, term or condition and Mortgagee shall
have the right to invoke any equitable right or remedy as though other remedies
were not provided for in this Mortgage.

            2.2. Appointment of Receiver. If an Event of Default shall have
occurred and be continuing, Mortgagee, shall, as a matter of right, be entitled
to the appointment of a receiver for the Mortgaged Property, and Mortgagor
hereby consents to such appointment and waives notice of any application
therefor.

            2.3 Remedies, etc. Cumulative. Each right, power and remedy of
Mortgagee provided for herein and now or hereafter existing at law or in equity
or by statute or otherwise shall be cumulative, and the exercise by Mortgagee of
any one or more of such rights, powers or remedies shall not preclude the
simultaneous or later exercise by Mortgagee of any or all such other rights,
powers or remedies.

            SECTION 3. MISCELLANEOUS


                                        8
<PAGE>

            3.1 Agreement. This Mortgage has been executed and delivered
pursuant to the Credit Agreement and is entitled to the benefits thereof.

            3.2 Notices. All notices, requests, demands and other communications
hereunder shall be given as provided in the Credit Agreement.

            3.3 No Oral Modification. This Mortgage may not be changed or
terminated orally.

            3.4 Terms Subject to Applicable Law. All rights, powers and remedies
provided herein may be exercised only to the extent that the exercise thereof
does not violate any applicable law, and are intended to be limited to the
extent necessary so that they will not render this Mortgage invalid,
unenforceable or not entitled to be recorded, registered or filed under any
applicable law. In the event any one or more of the terms contained in this
Mortgage shall be held to be invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other term
hereof.

            3.5 Successors and Assigns. All terms of this Mortgage shall run
with the land and bind Mortgagor, its successors and assigns, and all persons
claiming under or through Mortgagor or any such successor or assign and shall
inure to the benefit of Mortgagee, and its successors and assigns.

            3.6 Warranty of Title. Mortgagor represents that it has good and
marketable fee simple title to the Mortgaged Property, subject only to the
permitted exceptions shown on the title insurance policy delivered to the
Mortgagee pursuant to subsection 5.1(r) of the Credit Agreement and to other
Liens permitted under Section 7.3 of the Credit Agreement, and has the right to
mortgage the Mortgaged Property. Mortgagor will warrant and defend to Mortgagee
such title and the lien and interest of this Mortgage as a valid and enforceable
first mortgage thereon.

            3.7 Multiple Security. If (a) the Premises shall consist of one or
more parcels, whether or not contiguous and whether or not located in the same
county, or (b) in addition to this Mortgage, Mortgagee shall now or hereafter
hold or be the beneficiary of one or more additional mortgages, liens, deeds of
trust or other security (directly or indirectly) for the indebtedness secured
hereby upon other property in the State in which the Premises are located
(whether or not such property is owned by Mortgagor or by others) or (c) both
the circumstances described in clauses (a) and (b) shall be true, then to the
fullest extent permitted by law, Mortgagee may, at its election, commence or
consolidate in a single trustee's sale or foreclosure action, as the case may
be, all sale or foreclosure proceedings against all such collateral securing the
indebtedness secured hereby (including the Mortgaged Property), which action may
be brought or consolidated in the courts of, or sale conducted in, any county in
which any of such collateral is located. Mortgagor acknowledges that the right
to maintain a consolidated sale or foreclosure action is a specific inducement
to Mortgagee and the Lenders to extend the indebtedness secured hereby, and
Mortgagor expressly and irrevocably waives any objections to the commencement or
consolidation of the sale or foreclosure proceedings in a single action and any
objections to the laying of venue or based on the grounds of forum non
conveniens which it may now or hereafter have. Mortgagor further agrees that if
Mortgagee shall be prosecuting one or more sales, foreclosure or other
proceedings against a portion of the Mortgaged Property or against any
collateral other than the Mortgaged Property, which collateral directly or
indirectly secures the indebtedness secured hereby, or if Mortgagee shall have
obtained a judgment of foreclosure and sale or similar judgment against such
collateral (or, in the case


                                        9
<PAGE>

of sale, shall have met the statutory requirements therefor with respect to such
collateral), then, whether or not such proceedings are being maintained or
judgments were obtained in or outside the State in which the Premises are
located, Mortgagee may commence or continue any sale or foreclosure proceedings
and exercise its other remedies granted in this Mortgage against all or any part
of the Mortgaged Property and Mortgagor waives any objections to the
commencement or continuation of a foreclosure of this Mortgage or exercise of
any other remedies hereunder based on such other proceedings or judgments, and
waives any right to seek to dismiss, stay, remove, transfer or consolidate
either any action under this Mortgage or such other proceedings on such basis.
The commencement or continuation of proceedings to sell the Mortgaged Property,
to foreclose this Mortgage or the exercise of any other rights hereunder or the
recovery of any judgment by Mortgagee or the occurrence of any sale in any such
proceedings shall not prejudice, limit or preclude Mortgagee's right to commence
or continue one or more sales, foreclosure or other proceedings or obtain a
judgment against any other collateral (either in or outside the State in which
the Premises are located) which directly or indirectly secures the indebtedness
secured hereby, and Mortgagor expressly waives any objections to the
commencement of, continuation of, or entry of a judgment in such other sales,
foreclosure or proceedings or exercise of any remedies in such sales,
foreclosure or proceedings based upon any action or judgment connected to this
Mortgage, and Mortgagor also waives any right to seek to dismiss, stay, remove,
transfer or consolidate either such other sales, foreclosures or proceedings or
any sale or action under this Mortgage on such basis.

            3.8. Receipt of Copy. Mortgagor acknowledges that it has received a
true copy of this Mortgage.

            3.9. Future Advances. State Specific Clauses. [Insert additional

            (b) Subject to subsection (c) below, in the event of damage to or
destruction of the Trust Property, or in the event of a partial condemnation of
the Trust Property, all Loss Proceeds shall be paid to Grantor, and Grantor

            (c) If pursuant to Section 6.5(b) of the Credit Agreement Loss
Proceeds are required to be paid to the Administrative Agent and held as
collateral for application in accordance with the Security Documents, such Loss
Proceeds shall be applied, and repair and restoration shall be undertaken, as
follows: Grantor shall commence to repair and restore the Trust Property
pursuant to plans and specifications approved by Beneficiary, in its reasonable
discretion, within ninety (90) days from the date of such condemnation, damage
or destruction, and shall complete the same with reasonable diligence and as
promptly as may be practicable after Beneficiary approves the plans and
specifications. Any Loss Proceeds received in connection with such condemnation,
damage or destruction shall be payable to Beneficiary to be applied in
accordance with the following provisions:

            (i) If the Loss Proceeds received are less than $50,000, then such
proceeds shall be given to Grantor to be held in trust for Beneficiary and the
Lenders and applied only for the purpose of repairing, restoring, replacing or
rebuilding the Trust Property. Any excess held by Grantor, after such
restoration, may be retained by Grantor.

            (ii) In all other cases, the net amount of the Loss Proceeds on
account of such condemnation, damage or destruction to the Trust Property, after
reimbursement out of such proceeds for any costs and expenses (including
reasonable attorneys' fees and disbursements) for collection thereof (such net
proceeds and deposits, and any other deposits made therein as provided below,
being herein collectively called the "Fund") shall be received and held by
Beneficiary and applied in accordance with the following provisions:

                  (A) If the net amount of Loss Proceeds shall be insufficient
to pay the entire cost of restoring the Trust Property (as estimated by a
registered architect or professional engineer reasonably satisfactory to
Beneficiary, which estimate shall be delivered to Beneficiary before the
commencement of any such work), Grantor shall, prior to allowing such work to
commence, deposit the amount of the deficiency into the Fund, and thereafter
from time to time such additional amounts as shall be needed to meet any
increases in estimates made by said registered architect or professional
engineer. If the net amount of said proceeds shall be insufficient to pay the
entire cost of such work, Grantor shall pay and be responsible for the
deficiency.

                  (B) Grantor shall be entitled out of the Fund to ninety
percent (90%) of the cost of making temporary repairs or doing other work to
protect the Trust Property pending adjustment of the insurance loss or the
making of permanent repairs, restoration, replacements or rebuilding.

                  (C) Grantor shall be entitled out of the Fund to payments from
time to time as the work progresses in amounts equal to a maximum of ninety
percent (90%) of the cost of labor and material incorporated into and used in
such work and architects' and engineers' fees, provided and upon condition that
(1) the work shall have been done in accordance with the plans and
specifications therefor, any other requirements contained in this Section, (2)
the remaining amount of the Fund shall be sufficient to pay in full for all of
the remaining work, and (3) a certificate of an independent registered architect
or professional engineer satisfactory to Beneficiary stating that such
conditions have been met shall have been delivered to Beneficiary.

                  (D) Grantor shall be entitled out of the Fund so the remaining
ten percent (10%) of the cost of labor and material incorporated into and used
in such work and architects' and engineers' fees when such work shall have been
fully completed and paid for and a certificate of an


                                        5
<PAGE>

independent registered architect or professional engineer satisfactory to
Beneficiary stating that such conditions have been met shall have been delivered
to Beneficiary.

                  (E) At Beneficiary's request, Grantor shall furnish to
Beneficiary at the time of any such progress or final payment, a title search or
other evidence reasonably satisfactory to Beneficiary (including waivers of lien
agreements from the general contractor supervising such work, or in the absence
of a general contractor, all contractors, materialmen and others providing labor
or services in connection therewith) that the Trust Property and the interests
therein of Beneficiary and Grantor shall be free from (1) liens for labor
performed or claimed to have been performed or materials supplied or claimed to
have been supplied, unless the same are bonded, and (2) chattel mortgages,
conditional sales contacts, title retention agreements, security interests and
agreements, financing agreements, financing statements and any similar
agreements, in connection with such work. Notwithstanding any provision to the
contrary, Grantor shall not be entitled to any amount out of the Fund (x) while
any such lien or other encumbrance shall remain unsatisfied of record, unless in
the case of a lien the same is bonded or (y) during the continuance of any Event
of Default.

                  (F) If any of such Loss Proceeds shall remain after the full
completion of, and payment for, such repairs, restoration, replacements or
rebuilding, the excess shall be paid to Grantor.

            1.9 Inspection. Beneficiary and any persons authorized by
Beneficiary shall have the right to enter and inspect the Trust Property at all
reasonable times upon reasonable notice.

            1.10 Utilities. Grantor shall pay when due all utility, sprinkler
system and protective services charges which are furnished to the Trust
Property, whether public or private.

            1.11 Action by Mortgagee to Preserve Trust Property. Should Grantor
fail to make any payment or do any act as and in the manner provided in this
Deed of Trust, Beneficiary without obligation so to do and without notice to or
demand upon Grantor and without releasing Grantor from any obligation, may make
or do the same in such manner and to such extent as it may deem necessary
therefor. Grantor shall, upon demand therefor by Beneficiary pay all reasonable
costs and expenses incurred by Beneficiary in connection with the exercise by
Beneficiary of the foregoing rights (including, without limitation, reasonable
attorneys' fees and expenses) together with interest thereon from the date of
each such expenditure until paid, calculated at the Default Rate and the same
shall be deemed part of the indebtedness secured by this Deed of Trust.

            SECTION 2. DEFAULT

            2.1 Remedies. (a) Upon the occurrence of any Event of Default, in
addition to any other rights and remedies Beneficiary may have pursuant to the
Credit Documents, or as provided by law, and without limitation, (a) if such
event is an Event of Default specified in clause (a) or (b) of Section 8 of the
Credit Agreement, automatically the indebtedness secured hereby and all other
amounts owing under the Deed of Trust and the other Credit Documents immediately
shall become due and payable, and (b) if such event is any other Event of
Default, by notice to Grantor, Beneficiary may declare the indebtedness secured
hereby and all other amounts payable under this Deed of Trust and the other
Credit Documents to be immediately due and payable. Except as expressly provided
above in this Section, presentment, demand, protest and all other notices of any
kind are hereby expressly waived. In addition, upon the occurrence of any Event
of Default, Beneficiary may immediately take such action, without notice or
demand, as it deems advisable to


                                        6
<PAGE>

protect and enforce its rights against Grantor and in and to the Trust Property,
including, without limitation, the following actions, each of which may be
pursued concurrently or otherwise, at such time and in such manner as
Beneficiary may determine, in its sole discretion, without impairing or
otherwise affecting the other rights and remedies of Beneficiary:

            (i) Beneficiary may, to the extent permitted by law, elect to cause
      the Trust Property or any part thereof to be sold as follows: The Trustee,
      his successor or substitute, is authorized and empowered and it shall be
      his special duty at the request of Beneficiary to enter and take
      possession of the Trust Property, and before or after such entry to
      [INSERT STATE SPECIFIC REQUIREMENTS FOR SALE] advertise the sale of the
      Trust Property for ___ days by ___ weekly notices in some newspaper
      published in the county where such sale is to be made and to sell the
      Trust Property or any part thereof situated in the State(s) of [________]
      at the [courthouse door of any county] in the State(s) of
      [_______________] in which any part of the Trust Property is situated, at
      public vendue to the highest bidder for cash between the hours of
      [__________________] of the day fixed in the notice. Said sale shall be
      free from equity of redemption, statutory right of redemption, homestead,
      dower, and all other rights and exemptions of every kind, all of which are
      hereby waived, and the Trustee shall execute a conveyance to the purchaser
      and deliver possession to the purchaser, which Grantor binds itself shall
      be given without obstruction, hindrance or delay. Any sale made by the
      Trustee hereunder may be as an entirety or in such parcels or parts as
      Beneficiary may request, and any sale may be adjourned by announcement at
      the time and place appointed for such sale without further notice except
      as may be required by law. The sale by the Trustee of less than the whole
      of the Trust Property shall not exhaust the power of sale herein granted,
      and the Trustee is specifically empowered to make successive sale or sales
      under such power until the whole of the Trust Property shall be sold; and,
      if the proceeds of such sale of less then the whole of the Trust Property
      shall be less than the aggregate of the indebtedness secured hereby and
      the expense of executing this trust as provided herein, this Deed of Trust
      and the lien hereof shall remain in full force and effect as to the unsold
      portion of the Trust Property just as though no sale had been made;
      provided, however, that Grantor shall never have any right to require the
      sale of less than the whole of the Trust Property but Beneficiary shall
      have the right, at its sole election, to request the Trustee to sell less
      than the whole of the Trust Property. After each sale, the Trustee shall
      make to the purchaser or purchasers at such sale good and sufficient
      conveyances, conveying the property so sold to the purchaser or purchasers
      with general warranty of title as then possessed by the Trustee, and after
      each sale the Trustee shall receive the proceeds of said sale or sales and
      apply the same as herein provided. The power of sale granted herein shall
      not be exhausted by any sale held hereunder by the Trustee or his
      substitute or successor, and such power of sale may be exercised from time
      to time and as many times as the Beneficiary may deem necessary until all
      the Trust Property has been duly sold and all secured indebtedness has
      been fully paid. In the event any sale hereunder is not completed or is
      defective in the opinion of the Beneficiary, such sale shall not exhaust
      the power of sale hereunder and the Beneficiary shall have the right to
      cause a subsequent sale or sales to be made hereunder. Any and all
      statements of fact or other recitals made in any deed or deeds given by
      the Trustee or any successor or substitute appointed hereunder as to
      nonpayment of the indebtedness secured hereby or as to the occurrence of
      any default, or as to Beneficiary having declared all such indebtedness to
      be due and payable, or as to the request to sell, or as to notice of time,
      place and terms of sale and the properties to be sold having been duly
      given, or as to the refusal, failure or inability to act of the Trustee or
      any substitute or successor, or as to the appointment of any substitute or
      successor, shall be taken as prima facie evidence of the truth of the
      facts so stated and


                                        7
<PAGE>

      recited. [The Trustee, his successor or substitute, may appoint or
      delegate any one or more persons as agent to perform any act or acts
      necessary or incident to any sale held by the Trustee, including the
      posting of notices and the conduct of sale, but in the name and on behalf
      of the Trustee, his successor or substitute.] This Deed of Trust shall be
      effective as a mortgage as well as a deed of trust and upon the occurrence
      of a default may be foreclosed as to any of the Trust Property in any
      manner permitted by the laws of the State[s] of [_____________] or of any
      other state in which any part of the Trust Property is situated, and any
      foreclosure suit may be brought by the Trustee or by Beneficiary. In the
      event a foreclosure hereunder shall be commenced by the Trustee, or his
      substitute or successor, Beneficiary may at any time before the sale of
      the Trust Property direct the said Trustee to abandon the sale, and may
      then institute suit for the collection of the indebtedness and obligations
      secured hereby, and for the foreclosure of the lien of this Deed of Trust.
      It is agreed that if Beneficiary should institute a suit for the
      collection of the secured indebtedness and for the foreclosure of the lien
      of this Deed of Trust, Beneficiary may at any time before the entry of a
      final judgment in said suit dismiss the same, and require the Trustee, his
      substitute or successor to sell the property in accordance with the
      provisions of this Deed of Trust.

            (ii) Beneficiary may, to the extent permitted by applicable law, (A)
      institute and maintain an action of judicial foreclosure against all or
      any part of the Trust Property, (B) institute and maintain an action on
      the Subsidiaries' Guarantee, or (C) take such other action at law or in
      equity for the enforcement of this Deed of Trust or any of the Credit
      Documents as the law may allow. Beneficiary may proceed in any such action
      to final judgment and execution thereon for all sums due hereunder,
      together with interest thereon at the Default Rate and all costs of suit,
      including, without limitation, reasonable attorneys' fees and
      disbursements. Interest at the Default Rate shall be due on any judgment
      obtained by Beneficiary from the date of judgment until actual payment is
      made of the full amount of the judgment.

            (iii) Beneficiary may personally, or by its agents, attorneys and
      employees and without regard to the adequacy or inadequacy of the Trust
      Property or any other collateral as security for the indebtedness and
      obligations secured hereby enter into and upon the Trust Property and each
      and every part thereof and exclude Grantor and its agents and employees
      therefrom without liability for trespass, damage or otherwise (Grantor
      hereby agreeing to surrender possession of the Trust Property to
      Beneficiary upon demand at any such time) and use, operate, manage,
      maintain and control the Trust Property and every part thereof. Following
      such entry and taking of possession, Beneficiary shall be entitled,
      without limitation, (x) to lease all or any part or parts of the Trust
      Property for such periods of time and upon such conditions as Beneficiary
      may, in its discretion, deem proper, (y) to enforce, cancel or modify any
      lease on such property and (z) generally to execute, do and perform any
      other act, deed, matter or thing concerning the Trust Property as
      Beneficiary shall deem appropriate as fully as Grantor might do.

            (b) Beneficiary, in any action to foreclose this Deed of Trust in a
judicial procedure or in connection with the exercise of any non-judicial power
of sale by Trustee, shall be entitled to the appointment of a receiver. In case
of a trustee's sale or foreclosure sale, the Trust Property may be sold, at
Beneficiary's election, in one parcel or in more than one parcel and Beneficiary
is specifically empowered (without being required to do so, and in its sole and
absolute discretion) to cause successive sales of portions of the Trust Property
to be held.


                                        8
<PAGE>

            (c) In the event of any breach of any of the covenants, agreements,
terms or conditions contained in this Deed of Trust, Beneficiary or Trustee
shall be entitled to enjoin such breach and obtain specific performance of any
covenant, agreement, term or condition and Beneficiary and Trustee shall have
the right to invoke any equitable right or remedy as though other remedies were
not provided for in this Deed of Trust.

            2.2. Appointment of Receiver. If an Event of Default shall have
occurred and be continuing, Beneficiary, shall, as a matter of right, be
entitled to the appointment of a receiver for the Trust Property, and Grantor
hereby consents to such appointment and waives notice of any application
therefor.

            2.3 Remedies, etc. Cumulative. Each right, power and remedy of
Beneficiary provided for herein and now or hereafter existing at law or in
equity or by statute or otherwise shall be cumulative, and the exercise by
Beneficiary of any one or more of such rights, powers or remedies shall not
preclude the simultaneous or later exercise by Beneficiary of any or all such
other rights, powers or remedies.

            SECTION 3. MISCELLANEOUS

            3.1 Agreement. This Deed of Trust has been executed and delivered
pursuant to the Credit Agreement and is entitled to the benefits thereof.

            3.2 Notices. All notices, requests, demands and other communications
hereunder shall be given as provided in the Credit Agreement, except that
notices to Trustee shall be given at the address set forth at the beginning of
this Deed of Trust.

            3.3 No Oral Modification. This Deed of Trust may not be changed or
terminated orally.

            3.4 Terms Subject to Applicable Law. All rights, powers and remedies
provided herein may be exercised only to the extent that the exercise thereof
does not violate any applicable law, and are intended to be limited to the
extent necessary so that they will not render this Deed of Trust invalid,
unenforceable or not entitled to be recorded, registered or filed under any
applicable law. In the event any one or more of the terms contained in this Deed
of Trust shall be held to be invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other term
hereof.

            3.5 Successors and Assigns. All terms of this Deed of Trust shall
run with the land and bind Grantor, its successors and assigns, and all persons
claiming under or through Grantor or any such successor or assign and shall
inure to the benefit of Trustee and Beneficiary, and their respective successors
and assigns.

            3.6 Warranty of Title. Grantor represents that it has good and
marketable fee simple title to the Trust Property, subject only to the permitted
exceptions shown on the title insurance policy delivered to the Beneficiary
pursuant to subsection 5.1(r) of the Credit Agreement and to other Liens
permitted under Section 7.3 of the Credit Agreement, and has the right to
mortgage the Trust Property. Grantor will warrant and defend to Beneficiary such
title and the lien and interest of this Deed of Trust as a valid and enforceable
first deed of trust thereon.

<PAGE>

            3.7 Successor Trustee. Beneficiary shall have the right to appoint a
substitute, or a successor trustee, to act as Trustee hereunder by written
designation. Such right shall extend to the appointment of other successor and
substitute trustees successively until the indebtedness hereby secured has been
paid in full or until the Trust Property is sold hereunder, and each substitute
and successor trustee shall succeed to all of the rights and powers of the
original Trustee named herein. [ADD ADDITIONAL STATE SPECIFIC REQUIREMENTS]

            3.8 Multiple Security. If (a) the Premises shall consist of one or
more parcels, whether or not contiguous and whether or not located in the same
county, or (b) in addition to this Deed of Trust, Beneficiary shall now or
hereafter hold or be the beneficiary of one or more additional mortgages, liens,
deeds of trust or other security (directly or indirectly) for the indebtedness
secured hereby upon other property in the State in which the Premises are
located (whether or not such property is owned by Grantor or by others) or (c)
both the circumstances described in clauses (a) and (b) shall be true, then to
the fullest extent permitted by law, Beneficiary may, at its election, commence
or consolidate in a single trustee's sale or foreclosure action, as the case may
be, all sale or foreclosure proceedings against all such collateral securing the
indebtedness secured hereby (including the Trust Property), which action may be
brought or consolidated in the courts of, or sale conducted in, any county in
which any of such collateral is located. Grantor acknowledges that the right to
maintain a consolidated sale or foreclosure action is a specific inducement to
Beneficiary and the Lenders to extend the indebtedness secured hereby, and
Grantor expressly and irrevocably waives any objections to the commencement or
consolidation of the sale or foreclosure proceedings in a single action and any
objections to the laying of venue or based on the grounds of forum non
conveniens which it may now or hereafter have. Grantor further agrees that if
Trustee or Beneficiary shall be prosecuting one or more sales, foreclosure or
other proceedings against a portion of the Trust Property or against any
collateral other than the Trust Property, which collateral directly or
indirectly secures the indebtedness secured hereby, or if Beneficiary shall have
obtained a judgment of foreclosure and sale or similar judgment against such
collateral (or, in the case of a trustee's sale, shall have met the statutory
requirements therefor with respect to such collateral), then, whether or not
such proceedings are being maintained or judgments were obtained in or outside
the State in which the Premises are located, Beneficiary may commence or
continue any sale or foreclosure proceedings and exercise its other remedies
granted in this Deed of Trust against all or any part of the Trust Property and
Grantor waives any objections to the commencement or continuation of a sale of
the Premises or foreclosure of this Deed of Trust or exercise of any other
remedies hereunder based on such other proceedings or judgments, and waives any
right to seek to dismiss, stay, remove, transfer or consolidate either any
action under this Deed of Trust or such other proceedings on such basis. The
commencement or continuation of proceedings to sell the Trust Property in a
trustee's sale, to foreclose this Deed of Trust or the exercise of any other
rights hereunder or the recovery of any judgment by Beneficiary or the
occurrence of any sale by the Trustee in any such proceedings shall not
prejudice, limit or preclude Beneficiary's right to commence or continue one or
more sales, foreclosure or other proceedings or obtain a judgment against (or,
in the case of a trustee's sale, to meet the statutory requirements for, any
such sale of) any other collateral (either in or outside the State in which the
Premises are located) which directly or indirectly secures the indebtedness
secured hereby, and Grantor expressly waives any objections to the commencement
of, continuation of, or entry of a judgment in such other sales, foreclosure or
proceedings or exercise of any remedies in such sales, foreclosure or
proceedings based upon any action or judgment connected to this Deed of Trust,
and Grantor also waives any right to seek to dismiss, stay, remove, transfer or
consolidate either such other sales, foreclosure or proceedings or any sale or
action under this Deed of Trust on such basis.

            In connection with this opinion, we have examined originals or

kind, that (a) the Loan Documents constitute the valid and legally binding
obligations of each party to

the Loan Documents other than the Loan Parties, enforceable against such parties
in accordance with their respective terms, and (b) the execution, delivery and
performance by each Loan Party of each Loan Document to which it is a party do
not (i) contravene, or require any order, consent, approval, license,
authorization, validation, filing, recording, registration or exemption not
obtained or made under, any applicable provision of any law, statute, rule or
regulation (other than any law, statute, rule or regulation of the United States
of America or the State of New York and the Delaware General Corporation Law) or
any order, writ, injunction or decree of any court or other governmental
authority binding upon such Loan Party or (ii) contravene, or require any
consent not obtained under, any contractual obligation applicable to or binding
upon such Loan Party (other than the Transaction Documents).

            Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that:

            1. The Borrower has been duly incorporated and is validly existing
      and in good standing under the laws of the State of Delaware with
      corporate power and authority to conduct its business as now conducted and
      to own, or hold under lease, its assets and to enter into the Credit
      Agreement, the Notes, the Borrower Pledge and Security Agreement, and the
      Mortgages (collectively, the "Borrower Credit Documents") and perform its
      obligations thereunder. Based solely on certificates from public
      officials, we confirm that the Borrower is qualified to do business in
      each State where such qualification is required, except where the failure
      to be so qualified could not reasonably be expected to have a Material
      Adverse Effect.

            2. Holdings has been duly incorporated and is validly existing and
      in good standing under the laws of the State of Delaware with corporate
      power and authority to conduct its business as now conducted and to own,
      or hold under lease, its assets and to enter into the Parent Guarantee and
      the Parent Pledge and Security Agreement (collectively, the "Guarantor
      Documents") and perform its obligations

      thereunder. Based solely on certificates from public officials, we confirm
      that Holdings is qualified to do business in New York.

            3. The execution, delivery and performance of the Borrower Credit
      Documents have been duly authorized by all necessary corporate action of
      the Borrower, and the Borrower Credit Documents have been duly executed
      and delivered by the Borrower.

            4. The execution, delivery and performance of the Guarantor
      Documents have been duly authorized by all necessary corporate action of
      Holdings, and the Guarantor Documents have been duly executed and
      delivered by Holdings.

            5. Each of the Borrower Credit Documents (other than any Mortgage
      which by its terms is governed by the laws of a jurisdiction other than
      New York State) constitutes a legally valid and binding obligation of the
      Borrower, enforceable against the Borrower in accordance with its terms.

            6. Each of the Guarantor Documents constitutes a legally valid and
      binding obligation of Holdings, enforceable against Holdings in accordance
      with its terms.

            7. The execution and delivery of the Borrower Credit Documents by
      the Borrower, the borrowing and granting of security interests by the
      Borrower under the Borrower Credit Documents and the consummation of the
      Transaction on the date hereof do not: (a) violate any federal or New York
      statute, rule or regulation applicable to the Borrower or the Delaware
      General Corporation Law (including, without limitation, Regulation G, T, U
      or X of the Board of Governors of the Federal Reserve System, but
      excluding any government procurement statute or regulations issued
      pursuant thereto, as to which we understand that you have obtained the
      opinion of Fried, Frank, Harris, Schriver & Jacobsen), (b) violate the
      provisions of its certificate of incorporation or by-laws, (c) result in
      (i) the breach of or a default under any of the Transaction Documents to
      which the Borrower is a party or (ii) the creation of any lien under any
      of the Transaction Documents to which the Borrower is a party, except for
      liens arising under the Security Documents (as defined below), or (d)
      require any consents, approvals, authorizations, registrations,
      declarations or filings by the Borrower under any federal or New York
      State statute, rule or regulation applicable to the Borrower, except (i)
      the filing of the Financing Statements (as defined below) naming the
      Borrower as the debtor, (ii) approvals required by the Hart-Scott-Rodino
      Antitrust Improvements Act which have been obtained, (iii) the consents
      under the Assignment of Claims Act and (iv) those other consents,
      approvals, authorizations, registrations, declarations and filings
      required under any federal or New York State statute, rule or regulation
      and listed on Schedule 4.4 to the Credit Agreement.

            8. The execution and delivery of the Guarantor Documents by
      Holdings, the making of the guarantee and granting of the security
      interests by Holdings under the Guarantor Documents and the consummation
      of the Transaction on the date hereof do not: (a) violate any federal or
      New York statute, rule or regulation applicable to Holdings or the
      Delaware General Corporation Law (including, without limitation.
      Regulation G, T, U or X of the Board of Governors of the Federal Reserve
      System, but excluding any government procurement statute or regulations
      issued pursuant thereto, as to which we understand that you have obtained
      the opinion of Fried, Frank, Harris, Schriver & Jacobsen), (b) violate the
      provisions of its certificate of incorporation or by-laws, (c) result in
      (i) the breach of or a default under any of the Transaction Documents to
      which Holdings is a party or (ii) the creation of any lien under any of
      the Transaction Documents to which Holdings is a party, except for liens
      arising under the Security Documents (as defined below), or (d) require
      any consents, approvals, authorizations, registrations, declarations or
      filings by Holdings under any federal or state statute, rule or regulation
      applicable to Holdings, except (i) the filing of the Financing Statements
      (as defined below) naming Holdings as the debtor, (ii) approvals required
      by the Hart-Scott-Rodino Antitrust Improvements Act which have been
      obtained, (iii) the consents under the Assignment of Claims Act and (iv)
      those other consents, approvals, authorizations, registrations,
      declarations and filings required under any federal or New York State
      statute, rule or regulation and listed on Schedule 4.4 to the Credit
      Agreement.

            9. The provisions of the Borrower Pledge and Security Agreement are
      effective to create valid security interests in favor of the
      Administrative Agent in that portion of the collateral described in the
      Borrower Pledge and Security Agreement which is subject to Article 9 of
      the New York UCC (the "Borrower Collateral") as security for the payment,
      to the extent set forth therein, of all obligations of the Borrower to the
      Agents and the Lenders under the Borrower Credit Documents.

            10. The provisions of the Parent Pledge and Security Agreement are
      effective to create valid security interests in favor of the
      Administrative Agent in that portion of the collateral described in the
      Parent Pledge and Security Agreement which is subject to Article 9 of the
      New York UCC (the "Parent Collateral" and, together with the Borrower
      Collateral, the "Collateral") as security for the payment, to the extent
      set forth therein, of all obligations of the Holdings to the Agents and
      the Lenders under the Guarantor Documents.

            11. The UCC-1 financing statements naming the Borrower as debtor
      which are attached hereto as Exhibit A (the "Borrower Financing
      Statements") and the UCC-1 financing statements naming Holdings as debtor
      which are attached hereto

      as Exhibit B (the "Holdings Financing Statements"; the Borrower Financing
      Statements and the Holdings Financing Statements, collectively, the
      "Financing Statements") are in appropriate form for filing in the Office
      of the Secretary of State of New York, the Office of the New York City
      Register and the Office of the Suffolk County Clerk (collectively, the
      "Filing Offices"). Upon the proper filing of the Financing Statements in
      the Filing Offices, the security interest in favor of the Administrative
      Agent in the Collateral will be perfected to the extent a security
      interest in such Collateral can be perfected by filing a financing
      statement under the provisions of the New York UCC.

            12. Assuming the Administrative Agent takes possession of and holds
      the shares of capital stock listed on Schedule 1 to the Parent Pledge and
      Security Agreement (the "Pledged Shares"), delivered to the Administrative
      Agent pursuant to the Parent Pledge and Security Agreement, with undated
      stock powers duly indorsed in blank, in the State of New York, the Parent
      Pledge and Security Agreement will create a valid and perfected security
      interest in favor of the Administrative Agent in the rights in such
      Pledged Shares which Holdings has or has actual authority to convey, as
      security for the payment, to the extent set forth in the Parent Pledge and
      Security Agreement, of all obligations of Holdings to the Lenders under
      the Guarantor Documents.

            13. The Borrower's authorized capital stock consists of 100 shares
      of common stock, all of which have been duly authorized and validly
      issued, are fully paid and nonassessable, are free of preemptive rights
      and, based solely on our review of the Borrower's stock records, are owned
      of record by Holdings free and clear of all liens, claims, charges, or
      encumbrances other than Liens created or permitted by the Security
      Documents. Holdings has no direct or indirect Subsidiaries other than the
      Borrower.

            14. Assuming the Mortgage covering the Borrower's real property
      located in Hauppauge, New York (the "New York Mortgage") is recorded in
      the appropriate public records and that all necessary mortgage recording
      taxes have been paid, the New York Mortgage will constitute a valid and
      enforceable lien on the property described therein, securing the
      Borrower's obligations under the Notes.

            15. The Borrower is not an "investment company" as such term is
      defined in the Investment Company Act of 1940, as amended.

            16. Holdings is not an "investment company" as such term is defined
      in the Investment Company Act of 1940, as amended.

            17. The choice of New York law to govern each Loan Document in which
      such choice is stipulated is a valid and effective choice of law under the
      laws of the State of New York.

            Our opinions in paragraphs 5 and 6 above are subject to the effects
of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing. Our opinions in
paragraphs 5 and 6 above are also subject to the qualification that certain
remedial and exculpatory provisions of, and waivers of rights contained in, the
Borrower Pledge and Security Agreement, the Parent Pledge and Security Agreement
and the New York Mortgage (together, the "Security Documents") are or may be
unenforceable in whole or in part under the laws of the State of New York, but
such laws do not, in our opinion, make the remedies afforded by the Security
Documents inadequate for the practical realization of the benefits intended to
be provided thereby.

            Our opinions in paragraph 9, 10 and 11 above are limited to Article
9 of the New York UCC and our opinion in paragraph 12 above is limited to
Article 8 of the New York UCC and therefore those opinion paragraphs do not
address (i) the laws of jurisdictions other than New York, (ii) the laws of New
York except for Article 8 or 9, as the case may be, of the New York UCC, (iii)
collateral of a type not subject to Article 8 or 9, as the case may be, of the
New York UCC and (iv) what law governs perfection of the security interests
granted in the collateral covered by this opinion letter under New

York UCC ss. 9-103. Our opinions in paragraphs 9, 10, 11 and 12 above should be
interpreted in accordance with the Special Report by the TriBar Opinion
Committee: U.C.C. Security Interest Opinions. 49 Bus. Law. 359 (1993).

            With your permission, we express no opinion as to (a) the perfection
of the Administrative Agent's security interests in Pledged Securities with
respect to which a security interest may be perfected only through methods other
than the possession of certificates representing the Pledged Securities; (b) any
provision of the Loan Documents which is intended (i) to establish any standard
as the measure of the performance by any party thereto of such party's
obligations of good faith, diligence, fair dealing, reasonableness or care or
the fulfillment of the duties imposed on any secured creditor with respect to
the disposition or redemption of collateral, accounting for surplus proceeds of
collateral or accepting collateral in discharge of liabilities owed to any
creditor or unsecured creditor or (ii) to permit modification thereof only by
means of an agreement in writing signed by the parties thereto; (c) except as
set forth in paragraphs 9, 10, 11 and 12 above, the attachment, creation,
perfection, enforceability or priority of any liens or security interests
purported to be granted under the Loan Documents; (d) any provision of the Loan
Documents (i) requiring payment of attorneys' fees, except to the extent a court
determines such fees to be reasonable or (ii) waiving objections based on forum
non-conveniens; (e) the effect of the compliance or noncompliance with any
federal or state laws or regulations applicable to the Lenders or their
affiliates because of their legal or regulatory status or the nature of their
businesses; (f) any provision of the

Loan Documents insofar as it purports to grant a right of setoff in respect of
any Loan Party's or its subsidiaries' assets (i) to any person other than a
creditor of such Loan Party or subsidiary, as the case may be, or (ii) to any
Lender in an amount greater than the amount owing by such Loan Party or
subsidiary, as the case may be, to such Lender; (g) the right, title or interest
of any person in or to, or the condition of title or ownership of, or the
existence of, any property purported to be subject to the Loan Documents; (h)
Section 2.9(c) of the Credit Agreement (and corresponding provisions in each of
the other Loan Documents) insofar as they relate to post-judgment or default
interest rates or interest on overdue amounts; (i) any provision of the Loan
Documents which purports to require that any collateral or property be held in
trust or imposes fiduciary duties on any party thereto; (j) any provisions of
any Loan Document that provides that a Loan Party's liability thereunder shall
not be affected by action or failure to act on the part of the beneficiaries of
any Loan Document or by amendments or waivers of provisions of documents
governing the guaranteed or secured obligations; (k) with respect to the
validity, binding effect or enforceability of any provision of any Loan Document
which purports to authorize you to sign or file financing statements or other
documents without the signature of the applicable Loan Party (except to the
extent a secured party may execute and file financing statements without the
signature of the debtor under Section 9-402(2) of the New York UCC); (l) as to
the enforceability of the indemnification provisions of the Loan Documents
insofar as said provisions contravene public policy; and (m) the enforceability
of the provisions of any agreement or document to the extent

that such provisions constitute a waiver of illegality as a defense to
performance of contract obligations or any other defense to performance which
cannot, as a matter of law, be effectively waived.

            We wish to point out that (a) in the case of property that becomes
collateral under the Loan Documents after the date hereof, Section 552 of Title
11 of the United States Bankruptcy Code limits the extent to which property
acquired by a debtor after the commencement of a case under the Bankruptcy Code
may be subject to a security interest arising from a security agreement entered
into by the debtor before the commencement of such case and (b) the perfection
of the Administrative Agent's security interest in proceeds is limited to the
extent set forth in 9-306 of the New York UCC.

            In addition, we express no opinion as to the enforceability of any
provision of any Loan Document whereby any Loan Party purports to submit to the
subject matter jurisdiction of the United States District Court for the Southern
District of New York. We note the limitations of 28 U.S.C. ss. 1332 on federal
court jurisdiction where diversity of citizenship is lacking, and we also note
that such submissions cannot supersede that court's discretion in determining
whether to transfer an action from one federal court to another under 28 U.S.C.
ss. 1404(a).

            We are members of the Bar of the State of New York and we express no
opinion as to the laws of any jurisdiction other than the federal laws of the
United States of America, the laws of the State of New York and the General
Corporation Law of the State of Delaware. We express no opinion as to the
enforceability, attachment, creation,

The Lenders Listed on Schedule I hereto

Ladies and Gentlemen:

      We are acting as special counsel to L-3 Communications Corporation, a
Delaware corporation (the "Company"), regarding Federal Government contract
matters, in connection with the Credit Agreement dated April 30, 1997. We are
delivering this opinion pursuant to Section 5.1(p)(i) of the Credit Agreement.
Capitalized terms used herein have the meaning given them in the Credit
Agreement unless such terms are otherwise defined herein.

      Since we have acted only as special counsel to the Company, we have
limited knowledge of the affairs of the Company. This opinion is therefore based
on such knowledge of the affairs of the Company as we may have acquired in the
course of the instant representation. We convened our review on February 20,
1997 and, as instructed by the client, completed the review by February 25,
1997. In connection with our engagement, we visited Communications Systems,
Camden, NJ; Wideband, Salt Lake City, Utah; Advanced Recorders, Sarasota,
Florida; Conic, San Diego, California; and Display Systems, Atlanta, Georgia;
Telemetry & Instrumentation, San Diego, California and Randtron, Menlow Park,
California. We did not visit Hycor, Microcom and Narda East and West. In
connection with this review, we reviewed only those contracts specified on
Exhibit A. Accordingly, the opinions set forth below are limited only to those
contracts.

      To the extent that it may be relevant to the opinions expressed herein, we
have assumed that the parties to the agreements described herein (other than the
parties whose actions are the

subject of our opinions) have the power to enter into and perform such
agreements and that such agreements have been duly authorized, executed and
delivered by, and constitute legal, valid and binding obligations of, such
parties.

      We have examined and relied upon the originals, or certified, conformed or
reproduced copies of all records, documents, certificates or other instruments
as in our judgment are necessary or appropriate to enable us to render the
opinions expressed below. In all such examinations we have assumed the
genuineness of all signatures on original or certified, conformed or
reproduction copies and the conformity to original or certified copies of all
copies submitted to us as conformed or reproduction copies. As to various
questions of fact relevant to such opinions, we have relied upon, and assumed
the accuracy of, certificates of public officials and oral or written statements
or certificates of officers or representatives of the Company and others.

      Based upon and subject to the foregoing, and further subject to the
limitations and qualifications below, we are of the opinion that as of the date
hereof:

                  (i) None of the execution, delivery or performance by the Loan
            Parties of the Credit Agreement or the transactions contemplated
            thereby, compliance by the Loan Parties with the provisions of the

            transactions contemplated thereby: (i) with respect to U.S.
            Government procurement matters (limited to our review of the

            administrative agency or other federal governmental body, agency or
            official having authority over government procurement matters
            (except for those governmental consents, approvals, authorizations
            or other orders of, or registrations or filings with, any federal
            court, federal regulatory body, U.S. administrative agency or other
            federal governmental body, agency or official having authority over
            federal government procurement matters contemplated in the

                               MATERIAL LITIGATION


      o     Universal Navigation Corp., et al. v. Loral Corporation, et al.: the
            Borrower's Aviation Recorders operation ("Aviation Recorders") is
            subject to a suit by Universal Avionics Systems Corporation
            ("Universal"). Universal is seeking to recover at least $15 million
            in damages it alleges it incurred as a result of certain actions by
            Aviation Recorders in the cockpit voice recorder ("CVR") business.
            If this matter were determined adversely to the Borrower in a
            non-appealable final judgment, the Borrower could also be subject to
            treble damages. Universal's complaint contains the following claims:
            (i) antitrust claims alleging that Aviation Recorders has attempted
            to monopolize the CVR business by, among other things, its
            institution and maintenance of a bid protest, "petitioning" of the
            Federal Aviation Administration and foreign aviation authorities
            regarding CVR certification requirements and its marketing
            activities, and (ii) Lanham Act and common law claims arising out of
            alleged false statements regarding Universal's or Aviation
            Recorders' CVRs. Management believes that there are substantial
            defenses to Universal's claims and intends to defend itself
            vigorously.

I.    The following are instances in which Lockheed Martin does not own, free
      and clear of all Liens all right, title and interest in Intellectual
      Property used primarily in the Business:

      1.    Unisys has not yet provided Assignment documents for a number of
            patents and patent applications developed at Wideband Systems.

      2.    Allegation by Purdue that Unisys/Loral (Wideband Systems) has
            infringed two Purdue patents (4,191,031 and 4,222,115); Loral sent
            a response on 3/1/96 denying any infringement; no further
            correspondence has been received from Purdue.

      3.    Unisys claims that it should have retained ownership to two patent
            applications which Loral claimed ownership to; these are on the
            Transferred Asset List (08/606,285 and 08/606,378); Lockheed Martin
            has taken the position that they are owned by Lockheed Martin.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors of
 Lockheed Martin Corporation:

      We have audited the accompanying combined balance sheet of the Lockheed
Martin Predecessor Businesses, as defined in Note 1 to the financial statements,
(the "Businesses") as of December 31, 1996 and the related combined statements
of operations and changes in invested equity and cash flows for the year then
ended. These financial statements are the responsibility of the Businesses,
management. Our responsibility is to express an opinion on these financial
statements based on our audit. We did not audit the financial statements of the
Communications Systems Division, which statements represent total assets and
sales constituting 35 percent and 30 percent of the related combined totals.
These 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
Communication Systems Division, is based solely on the report of the other
auditors.

      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 tax 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 and the report of other auditors provide a reasonable
basis for our opinion.

      In our opinion, based on our audit and the report of the other auditors,
the financial statements referred to above present fairly, in all material
respects, the combined financial position of the Lockheed Martin Predecessor
Businesses as of December 31, 1996 and their combined results of operations and
cash flows for the year then ended, in conformity with generally accepted
accounting principles.

Board of Directors
Lockheed Martin Corporation

We have audited the combined balance sheets of Lockheed Martin Communications
Systems Division, as defined in Note 1 to the financial statements, as of
December 31, 1996 and 1995, and the related combined statements of operations
and changes in invested equity, and cash flows for each of the three 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 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 tax basis, evidence supporting

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 1995, 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 each of the
two years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                             (Dollars in thousands)


1. Background and Description of Businesses

      On January 31, 1997, Lockheed Martin Corporation ("Lockheed Martin"),
Lahman Brothers Holdings Inc. ("Lehman"), Frank C. Lanza ("Lanza") and Robert V.
LaPenta ("LaPenta") entered into a Memorandum of Understanding regarding the
transfer of certain businesses of Lockheed Martin to a newly formed corporation
"Newco" owned by Lockheed Martin, Lehman, Lanza and LaPenta. The businesses
proposed to be transferred include Lockheed Martin's Wideband Systems, Division,
Communications Systems Division and Products Group, comprising eleven autonomous
operations (collectively the "Lockheed Martin Predecessor Businesses" or the
"Businesses"). Also included in the transaction is the acquisition of a
semiconductor product line of another business and certain leasehold
improvements in New York City.

      Effective April 1, 1996, Lockheed Martin acquired substantially all the
assets and liabilities of the defense businesses of Loral Corporation (Loral),
including the Wideband Systems Division and the Products Group. The acquisition
of the Wideband Systems Division and Products Group businesses (the "Acquired
Businesses") has been accounted for as a purchase by Lockheed Martin
Communications Systems Division ("Division"). The acquisition has been reflected
in these financial statements based on the purchase price allocated to those
acquired businesses by Lockheed Martin. As such, the accompanying combined
financial statements reflect the results of operations of the Division and the
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 assets and liabilities recorded in connection with the
purchase price allocation were $400,993 and $113,190, respectively.

      Had the acquisition of Wideband Systems Division and the Products Group
occurred on January 1, 1995, the unaudited pro forma sales and net income for
the years ending December 31, 1996 and 1995 would have been $675,596 and
$14,351, and $691,136 and $4,790, 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, 1995.

      The Businesses are suppliers of sophisticated secure communication systems
and specialized communication products including secure, high data rate
communication systems, commercial fixed wireless communication products,
microwave components, avionic displays and recorders and instrument products.
The Company's consumers included the Department of Defense, selected U.S.
government intelligence agencies, major aerospace/defense prime contractors and
commercial customers. The Businesses operate primarily in one industry segment,
electronic components and systems.

      Substantially all the Businesses' 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 permission 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.

      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 Businesses' programs;
however, in the event that U.S. Government expenditures for products of the type
manufactured by the Businesses 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 Businesses.

2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

      The accompanying combined financial statements reflect the Businesses'
assets, liabilities and operations included in Lockheed Martin's historical
financial statements that will be transferred to Newco. Intercompany accounts
between Lockheed Martin and the Businesses have been included in invested
equity. Significant inter-business transactions and balances have been
eliminated. The assets and operations of the semiconductor product line and
certain other facilities, which are not material to the combined financial
statements, have been excluded from the combined financial statements.

      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, 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.

Sales and Earnings

      Sales and profits on cost reimbursable contracts are recognized as costs
are incurred. Sales and estimated profits under 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. Sales under short-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. Amounts representing
contract change orders or claims are included in sales only when they can be
reliably estimated and realization is probable. 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.

Contracts in Process

      Costs accumulated under long-term contracts 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. Contracts in process contain ILLEGIBLE relating to contracts and
programs for which the related operating cycles are longer that one year. In
accordance with industry practice, these amounts are included in current assets.

Property, Plant and Equipment

      Property, plant and equipment are stated at cost. Depreciation is provided
primarily using an accelerated method over the estimated useful lives (5 to 20
years) of the related assets. Leasehold improvements are amortized over the
shorter of the lease term or the estimated useful life of the improvements.

Intangibles

      Intangibles, primarily 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 primarily over a 40-year period. Other intangibles are


                                       7
<PAGE>

                     LOCKHEED MARTIN PREDECESSOR BUSINESSES
               NOTES TO COMBINED FINANCIAL STATEMENTS--(continued)
                             (Dollars in thousands)


amortized over their estimated useful lives which range from 11-15 years.
Amortization expense was $10,115, $6,086 and $6,086 for 1996, 1995, and 1994,
respectively. Accumulated amortization was $26,524 and $16,738 at December 31,
1996 and 1995, respectively.

      Intangibles 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. As of
December 31, 1996 and 1995, approximately $4,400 and $7,500, respectively of
unamortized RFA and RAA costs were recorded on the Businesses' combined balance
sheet in other current assets and other assets.

      The carrying values 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 required over the remaining
amortization period, the Division's carrying values related to the intangible
assets are reduced by the estimated shortfall of cash flows.

Research and Development and Similar Costs

      Research and development costs sponsored by the Businesses include
research and development and bid and proposal effort related to government
products and services. These costs are 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 contract costs.

Financial Instruments

      At December 31, 1996, the carrying value of the Businesses' financial
instrument, such as receivables, accounts payable and accrued liabilities,
approximate fair value, based on the short-term maturities of these instruments.

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 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 required 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 January 1, 1994, the Businesses adopted Statement of Financial
Accounting Standards No. 112, "Employers' Accounting for Postretirement
Benefits" ("SFAS 112"). SFAS 112 requires that the cost 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 combined
results of operations of the Businesses.

3. Transactions with Lockheed Martin

      The Business rely 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 Businesses, 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
Businesses been independent entities. The following describes the related party
transactions.

Sales of Products

      The Businesses sell products to Lockheed Martin and its affiliates, not
sales for which were $70,658, $25,874, and $9,983 in 1996, 1995 and 1994,
respectively, included in Contracts in Process are receivables from Lockheed
Martin and its affiliates of $10,924 and $30 at December 31, 1996 and 1995,
respectively.

Allocation of Corporate Expenses

      The amount of allocated corporate expenses reflected in these combined
financial statements has been estimated primarily on an allocation methodology
prescribed by government regulations pertaining to government contractors.
Allocated costs to the Businesses were $10,057, $2,964 and $4,141 in 1996, 1995
and 1994, respectively.

Pensions

      Certain of the Businesses participate 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 is 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 liability or asset is reflected in the accompanying
combined financial statements. The Businesses have been allocated pension costs
based upon participant employee headcount. Net pension expense included in the
accompanying financial statements was $7,027, $4,134, and $3,675 in 1996, 1995
and 1994, respectively.

Postretirement Health Care and Life Insurance Benefits

      In addition to participating in Lockheed Martin-sponsored pension plans,
certain of the Businesses provide varying levels of health care and life
insurance benefits for retired employees and dependents. Participants are
eligible for these benefits when they retire from 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 [ILLEGIBLE] 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 financial statements. The Businesses have been
allocated postretirement benefits cost based on participant employee headcount.

Employee Savings Plans

      Under the various employee savings plans sponsored by Lockheed Martin, the
Businesses match the contributions of participating employees up to a designated
level. The extent of the match, vesting terms and the form of the matching
contributions vary among the plans. Under the plans, the matching contributions,
in cash, common stock or both, for 1996, 1995 and 1994 were $3,940, $1,478, and
$1,842, respectively.

Interest Expenses

      Interest expense has been allocated to the Businesses 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 defense business
of Loral Corporation ("Loral") has been assumed to be fully financed by debt.

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

                                            For the years ended December 31,

Income Taxes

      The Businesses are 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 is computed as if the Businesses were a separate taxpayer;
accordingly, the provision for income taxes is 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 recognized 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.

Statement of Cash Flows

      The Businesses participate in Lockheed Martin's cash management system,
under which all cash is received and payments are made by Lockheed Martin. All
transactions between the Businesses and Lockheed Martin have been accounted for
as settled in cash at the time such transactions were recorded by the
Businesses.

                                                 ========            =======

      The U.S. Government has title to, or a security interest in, inventories
to which program payments are applied. Unbilled contract receivables represent
accumulated costs and profits earned but not yet billed to customers at
year-end. The Businesses believe that substantially all such amounts will be
billed and collected within one year.

The following data has been used in the determination of cost of sales:

6. Income Taxes

      The provision for income taxes was calculated by applying statutory tax
rates to the reported pretax income 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.
For the years ended December 31, 1996, 1995 and 1994, it is estimated that the
provision for deferred taxes represent ($2,143), $3,994 and $1,252,
respectively. Substantially all the income of the Businesses are from domestic
operations.

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

                                                            1996    1995   1994
                                                            ----    ----   ----
Statutory Federal income tax rate                             35%     34%    34%
Amortization of cost in excess of net assets acquired          2     529     31
Research and development and other tax credits                (2)
State and local income taxes, net of Federal
 income tax benefits and state and local income tax credits    6     101     12
Foreign sales corporation tax benefit                         (1)
Other, net                                                            17      1
                                                             ---     ---    ---
Effective income tax rates                                    40%    681%    78%
                                                             ===     ===    ===

         The difference between the statutory Federal income tax rate and the
effective income tax rate in 1995 and 1994 is primarily due to the amortization
of cost in excess of net assets acquired which is not deductible for income tax
purposes.

7. Sales to Principal Customers

         The Businesses operate primarily in one industry segment, electronic
components and systems. Sales to principal customers are as follows:

8. Commitments and Contingencies

      The Businesses lease certain facilities and equipment under agreements
expiring at various dates through 2011. At December 31, 1996, future minimum
payments for noncancellable operating leases with initial or remaining terms in
excess of one year are $11,400 for each of the years 1992 through 2001, and
$12,300 in total thereafter.

      Leases covering major items of real estate and equipment contain renewal
and or purchase options which may be exercised by the Businesses. Rent expense,
net of sublease income from other Lockheed Martin entities, was $8,495, $4,772,
and $5,597 in 1996, 1995 and 1994, respectively.

                             (Dollars in thousands)

      Management is continually assessing the Businesses' 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, with respect to those environmental loss contingencies of which
management of the Businesses is aware, 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' results of 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 are 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 Businesses by a federal
grand jury could result in the Businesses 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 Businesses are 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
Businesses 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, terms of
litigation, claims or assessments will have a material adverse effect on the
financial position of results of the Businesses.

                         Report of Independent Auditors

Board of Directors
Lockheed Martin Corporation

We have audited the accompanying combined statement of net tangible assets of
the L-3 Communications Holdings, Inc. Acquired-Entities (as defined in Note 1)
as of December 31, 1996. This combined statement of net tangible assets is the
responsibility of Lockheed Martin Corporation's and the L-3 Communications
Holdings, Inc. Acquired-Entities' management. Our responsibility is to express
an opinion on the combined statement of net tangible assets 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 combined statement of net tangible assets is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined statement of net tangible
assets. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
combined statement of net tangible assets presentation. We believe that our
audit provides a reasonable basis for our opinion.

As described in Note 1, the accompanying combined statement of net tangible
assets as of December 31, 1996 has been prepared for the purpose of complying
with, and on the basis of, accounting practices specified in the Transaction
Agreement (as defined in Note 1). The combined statement of net tangible assets
is not intended to be a presentation in conformity with generally accepted
accounting principles, nor is the statement intended to be a compete
presentation of the L-3 Communications Holdings, Inc. Acquired-Entities'
combined assets, liabilities and net tangible assets.

In our opinion, the combined statement of net tangible assets referred to above
presents fairly, in all material respects, the net tangible assets of the L-3
Communications Holdings, Inc. Acquired-Entities at December 31, 1996, on the
basis of accounting described in Notes 1 and 2. The accompanying combined
statement of net tangible assets has been prepared assuming that the L-3
Communications Holdings, Inc. Acquired-Entities will continue as a going
concern.

This report is intended solely for the information and use of the parties
associated with the Transaction Agreement and should not be used for any other
purpose.

2. Summary of Significant Accounting Policies

Assumption Regarding Going Concern

The accompanying combined statement of net tangible assets has been prepared
assuming that the L-3 Communications Acquired-Entities will continue as a going
concern.

Use of Estimates

The preparation of the combined statement of net tangible assets requires
management to make estimates and assumptions that affect reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
December 31, 1996. The most significant of these estimates and assumptions
relate to contract estimates of total costs at completion and revenues in the
earnings recognition process, and commitments and contingencies. Actual results
could differ from those estimates.

As discussed in Note 1, the Transaction Agreement establishes the amount
reported for certain assets and liabilities. These amounts have been agreed to
by and among Lockheed Martin, Lehman, the Individual Purchasers and L-3
Communications and are not necessarily management's estimate of their value in
accordance with generally accepted accounting principles.

Revenue Recognition

The following L-3 Communications Acquired-Entities generally record revenues and
anticipated profits under long-term contracts on a percentage of completion
cost-to-cost basis of accounting where revenues and profits are recorded based
on the ration of costs incurred to estimated total costs at completion:

      o Wideband Systems,
      o Communications Systems,
      o Display Systems,
      o Microcom, and
      o Hycor.


                                                                               7

         Notes to Combined Statement of Net Tangible Assets (continued)

2. Summary of Significant Accounting Polices (continued)

Revenue Recognition (continued)

The following L-3 Communications Acquired-Entities generally record revenues and
profits on products and services essentially under commercial terms and
conditions as units are shipped or specified tasks are completed; or on a
percentage of completion basis, using units of delivery as to measurement basis
for effort expended:

      o     Advanced Recorders,

      o     Conic,

      o     Telemetry & Instrumentation

      o     Randtron,

      o     Microwave-Narda East, end

      o     Microwave-Narda West.

For all L-3 Communications Acquired-Entities, revenues under
cost-reimbursement-type contracts are recorded as costs are incurred. Applicable
estimated profits are included in earnings in the proportion that incurred costs
bear to total estimated costs.

Revenues and earnings on contracts are based, in part, on estimates. These
estimates are revised periodically and adjustments to revenues and earnings
resulting from such revisions are recorded on a cumulative basis in the period
of revision. Incentives or penalties and awards applicable to performance on
contracts are considered in estimating revenues and profit rates and are
recorded when there is sufficient information to assess anticipated contract
performance. Amounts representing contract change orders, claims or other items
are included in revenues only when they can be reliably estimated and
realization is probable.

Any anticipated losses on contracts or programs are charged to earnings when
identified. Such losses encompass all costs, including general and
administrative expenses for L-3 Communications Acquired-Entities that include
general and administrative expenses in inventory, allocable to the contracts.
The L-3 Communications Acquired-Entities that expense general and administrative
expenses as incurred exclude such costs in determining anticipated losses.
Revenue arising from change orders or the claims process is not recognized
either as income or as an offset against a potential loss until it can be
reliably estimated and its realization is probable.


                                                                               8

         Notes to Combined Statement of Net Tangible Assets (continued)

2. Summary of Significant Accounting Polices (continued)

General and Administrative Expenses

The following L-3 Communications Acquired-Entities allocate general and
administrative expenses to contracts in process and therefor are included in
operating costs and expenses at the time of revenue recognition:

      o     Wideband Systems,

      o     Communications Systems,

      o     Display Systems,

      o     Conic, and

      o     Randtron.

The following L-3 Communications Acquired-Entities charge general and
administrative expenses to operations as incurred:

      o     Advanced Recorders,

      o     Telemetry & Instrumentation

      o     Microcom,

      o     Hycor,

      o     Microwave-Narda East, end

      o     Microwave-Narda West.

Lockheed Martin's corporate general and administrative costs attributed to the
L-3 Communications Acquired-Entities are charged to the individual entity in
accordance with allocation methodologies determined by Lockheed Martin and
applied to Lockheed Martin's various business units. Such expenses could vary
significantly if the L-3 Communications Acquired-Entities are operating as an
unaffiliated entity.

Research and Development Costs

Customer-sponsored research and development costs are accounted for as direct
costs. Reimbursable company-sponsored research and development costs are
accounted for in accordance with the Acquired-Entities' policy for general and
administrative expenses.


                                                                               9

2. Summary of Significant Accounting Policies (continued)

Contracts in Process

Contracts in process are stated at the lower of cost or estimated net realizable
value, except for those items specifically addressed in the Transaction
Agreement. Costs on contracts in process represent recoverable costs incurred
for production; allocable operating overhead; and, based on entity policy,
research and development and general and administrative expanses, less amounts
attributed to cost of sales. Pursuant to contract provisions, agencies of the
U.S. Government and other customers have title to, or a security interest in,
certain inventories as a result of progress payments and advances. In accordance
with industry practice, contracts in process contain amounts relating to
contracts with long production cycles, a portion of which may not be realized
within one year.

Property, Plant and Equipment

Property, plant and equipment are stated at historical book value. Depreciation
is provided primarily using 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 improvement.

Certification Costs

As part of the normal course of doing business, the Advanced Recorders entity is
required to incur certification costs prior to the production of new products.
Advanced Recorders' policy is to capitalize these costs and amortize them on a
straight-line basis over a 10 year period. As of December 31, 1996,
approximately $3.4 million of unamortized certification costs are included in
the combined statement of net tangible assets.

Financial Instruments

At December 31, 1996, the carrying value of the L-3 Communications financial
instruments such as receivables, accounts payable and accrued liabilities
approximate fair vale, based on the short-term maturities of these instruments.


                                                                              10

2. Summary of Significant Accounting Policies (continued)

Concentration of Credit Risk

The L-3 Communications Acquired-Entities conduct business with the U.S.
Government and commercial enterprises. Financial instruments which potentially
expose the L-3 Communications Acquired-Entities to concentrations of credit risk
consist primarily of commercial receivables. To minimize this risk, ongoing
credit evaluations of commercial customers' financial condition are performed.
In addition, the L-3 Communications Acquired-Entities maintain allowances for
potential credit losses and such losses, in the aggregate, have not exceeded
management expectations. None of the L-3 Communications Acquired-Entities'
commercial receivables are individually significant.

Intercompany Accounts Receivable, Net

All accounts receivable from and accounts payable to Lockheed Martin entities
are deemed to be valid and realizable from and payable to the appropriate
Lockheed Martin entities.

3. Contracts in Process

Contracts in process reflected in the combined statement of net tangible assets
consist of the following as of December 31, 1996 (in thousands):

  Work in process                               $ 169,667
  Progress billing receivable                       4,631
  Less--Advances and progress payments            (43,260)

                                                =========
                                        
Work in process includes finished goods and raw materials held in inventory. In
addition, work in process includes unbilled costs incurred plus estimated
earnings that will be billed to the customer upon the completion of certain
milestones. Revenue which has not yet been billed is included in unbilled
receivables, some of which will not be billed within one year.

Under the contractual arrangements by which progress payments are received, the
U.S. Government asserts that it has a security interest in the contracts process
identified by the related contracts.


                                                                              11

5. Income Taxes

The accompanying combined statement of net tangible assets excludes the L-3
Communications Acquired-Entities' assets and liabilities relating to federal and
state income taxes, as discussed in Note 1.

6. Commitments and Contingencies

The L-3 Communications Acquired-Entities are 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 the
L-3 Communications Acquired-Entities were and are being conducted in accordance
with these requirements. Under government regulations, an indictment of an L-3
Communications Acquired-Entity could result in the L3 Communications
Acquired-Entity 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 L-3 Communications Acquired-Entities are 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 L-3 Communications Acquired-Entities are of the
opinion that, after taking into account certain provisions that have been made
with respect to these matters, pushdowns and matters addressed specifically in
the Transaction Agreement, the probability is remote that the ultimate
resolution of any such investigative actions, items of litigation, claims or
assessments will have a material adverse effect on the combined net tangible
assets of the L-3 Communications Acquired-Entities.

and substance to Lockheed Martin and Newco confirming that such consent is not
required.

            (d) If such consent, waiver or confirmation is not obtained with
respect to any such Government Contract or other Contract, as among the parties
hereto, Newco will obtain through a subcontracting arrangement or otherwise, and

Affiliated Transferor's) obligations, any and all claims, rights and benefits of
Lockheed Martin (or the applicable Affiliated Transferor) against a third party
thereto arising from any such Government Contract or Contract (including the
right to elect to terminate such Government Contract or Contract in accordance
with the terms thereof upon the request of Newco). Lockheed Martin (or the
applicable Affiliated Transferor) will promptly pay to Newco when received all
monies received by Lockheed Martin (or the applicable Affiliated Transferor)
under any Transferred Asset or any claim, right or benefit arising thereunder
not transferred pursuant to this Section 2.03.

                ADDITIONAL MATTERS RELATING TO THE CALCULATION OF
                               NET TANGIBLE ASSETS


      The Net Tangible Assets on the December Statement and the determination of
the Proposed Final Net Tangible Asset Amount and the Final Net Tangible Asset
Amount shall be in accordance with the terms and conditions of the Agreement and
in accordance with GAAP, except as provided in the December Statement and this
Attachment VI. The Proposed Final Net Tangible Asset Amount and the Final Net
Tangible Asset Amount will be determined on a basis consistent with the manner
in which the December Statement was prepared as disclosed in the notes to the
December Statement or as otherwise set forth in this Attachment VI. Therefore,
the Net Tangible Assets on the December Statement and the determination of the
Proposed Final Net Tangible Asset Amount and the Final Net Tangible Asset Amount
may differ from the closing balances of Lockheed Martin and the Business Units
on December 31, 1996 and at the close of business on the Effective Date or the
Closing Date, and the opening balances of Newco on the Closing Date for tax and
financial reporting purposes.

      Except as otherwise set forth in this Attachment VI, all principles,
classifications, methods, practices, assumptions and policies used in the
preparation of the December Statement (regardless of whether such principles,
classifications, methods, practices, assumptions and policies are in accordance
with GAAP) will be used or applied in the determination of the Proposed Final
Net Tangible Asset Amount and the Final Net Tangible Asset Amount. Accounting
pronouncements (as defined in Statement of Auditing Standards No. 69) not used
in the preparation of the December Statement will not be used in the
determination of the Proposed Final Net Tangible Asset Amount or the Final Net
Tangible Asset Amount. Except as otherwise set forth in this Attachment VI, the
estimates used in the determination of the Proposed Final Net Tangible Asset
Amount and the Final Net Tangible Asset Amount will be made on a basis
consistent with the principles, policies, methods, practices, factors and
underlying data used in making estimates in the preparation of the December
Statement.

      Following are additional agreements and clarifications with respect to the
determination of the Net Tangible Assets on the December Statement and the
determination of the Proposed Final Net Tangible Asset Amount and the Final Net
Tangible Asset Amount:

      Adjustment of Reserves and Valuation Accounts. In the determination of the
Proposed Final Net Tangible Asset Amount and the Final Net Tangible Asset
Amount, except as otherwise set forth in this Attachment VI, the amount of any
reserves or valuation accounts shall be determined by applying methods,
practices, assumptions, policies, factors and underlying data consistent with


                                                                  EXECUTION COPY
                                      VI-1
<PAGE>

those used in determining the reserves or valuation accounts included in the
December Statement, and there shall be no changes made to any reserves or
valuation accounts (including, without limitation, contract reserves, purchase
accounting reserves, allowances for bad debts, inventory reserves of any kind,
warranty reserves and other reserves), except to the extent that such changes
are required by changes in facts and events occurring after December 31, 1996
and before the Effective Date, it being further understood that there shall be
no increase in the Proposed Final Net Tangible Asset Amount or the Final Net
Tangible Asset Amount as a result of any reversal or other usage of reserves
unless such reversal or usage arises out of facts or events that occur after
December 31, 1996; provided, however, that notwithstanding the foregoing any
reversal or other usage of the Advanced Recorders IR & VLDS Inventory Reserve of
$1,100,000 million, the Advanced Recorders IR & VLDS Capitalized G&A reserve of
$800,000 or the Advanced Recorders IR & VLDS fixed asset reserve of $1,030,000
in connection with any sale of all or a portion of such business to a third
party prior to the Effective Date will result in a corresponding increase in the
Proposed Final Net Tangible Asset Amount or the Final Net Tangible Asset Amount.

      Inventory. For purposes of determining the Proposed Final Net Tangible
Asset Amount and the Final Net Tangible Asset Amount, the parties have agreed
contractually that an inventory observation, by the independent auditors as of
the Effective Date, will not be conducted. Furthermore, in the determination of
the Proposed Final Net Tangible Asset Amount and the Final Net Tangible Asset
Amount, the raw materials and finished goods inventory relating to the Business
shall be recorded at an amount equal to their book value as included in the
December Statement, except to the extent that changes are required by normal
business activities (purchases, transfers to/from work in process or cost of
sales relief resulting from shipment of products) occurring after December 31,
1996 but before the close of business on the Effective Date, in each case
calculated in accordance with the policies and practices reflected in the
December Statement, it being understood, however, that there shall be no changes
relating to the valuation, existence, or lack of existence of raw materials and
finished goods inventory.

      Reserves for Environmental Liabilities. The amount of the reserves for
Environmental Liabilities included in the December Statement shall be fixed at
$3.2 million and the amount used in the determination of the Proposed Final Net
Tangible Asset Amount and the Final Net Tangible Asset Amount shall be fixed at
$6.0 million.

      Exclusion of Certain Reserves and Liabilities. There shall not be included
in the Net Tangible Assets in the December Statement or in the determination of
the Proposed Final Net Tangible Asset Amount and the Final Net Tangible Asset
Amount any reserve or any liability to the extent such reserve or liability (i)
arises out of, results from or relates to an Excluded Asset or Excluded
Liability, (ii) arises out of, results from or relates to any action taken by
Newco or any of the Purchasers, including but


                                                                  EXECUTION COPY
                                      VI-2

not limited to any actions taken in connection with the Contemplated
Transactions, (iii) arises out of, results from or relates to any actions taken
or contemplated to be taken by Newco, Lockheed Martin, any of the Purchasers or
any of their Affiliates, contemporaneously with or subsequent to the Closing, or
(iv) is indemnified against by Lockheed Martin.

      Estimates at Completion ("EAC"). In the determination of the Proposed
Final Net Tangible Asset Amount and the Final Net Tangible Asset Amount, there
shall be no changes made to the EACs from those EACs used in the preparation of
the December Statement, except to the extent that such changes are required by
changes in facts and events occurring after December 31, 1996 and before the
Effective Date.

      Loss Contracts. In the determination of the Proposed Final Net Tangible
Asset Amount and the Final Net Tangible Asset Amount, there shall be no changes
made to the provisions for loss contracts from those used in the preparation of
the December Statement, except to the extent that such changes are required by
changes in facts and events occurring after December 31, 1996 and before the
Effective Date.

      Due Diligence Costs; Organization of Newco. There shall be no amount
accrued or reserved for in connection with the determination of the Proposed
Final Net Tangible Asset Amount and the Final Net Tangible Asset Amount for any
obligations or liabilities incurred in connection with Newco's, Lockheed
Martin's or the Purchaser's due diligence efforts in connection with the
Contemplated Transactions, including without limitation any fees and expenses of
the counsel, independent accountants or other agents, advisors or consultants of

                                   THE NOTES

Section 2.01.  Form and Dating.

          The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A-1 or A-2 hereto. The Notes may be issued
in the form of Definitive Notes or Global Notes, as specified by the Company.
The Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. Each Note shall be dated the date of its
authentication. The Notes shall be in denominations of $1,000 and integral
multiples thereof.

          The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby. However, to the extent any
provision of any Note conflicts with the express provisions of this Indenture,
the provisions of this Indenture shall govern and be controlling.

          Notes issued in global form shall be substantially in the form of
Exhibit A-1 or A-2 attached hereto (including the Global Note Legend and the
"Schedule of Exchanges in the Global Note" attached thereto). Notes issued in
definitive form shall be substantially in the form of Exhibit A-1 or A-2
attached hereto (but without the Global Note Legend and without the "Schedule
of Exchanges of Interests in the Global Note" attached thereto). Each Global
Note shall represent such of the outstanding Notes as shall be specified
therein and each shall provide that it shall represent the aggregate principal
amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from
time to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of a Global Note to reflect the amount of any
increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby shall be made by the Trustee or the Note Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

          Notes offered and sold in reliance on Regulation S shall be issued
initially in the form of the Regulation S Temporary Global Note (attached
hereto as Exhibit A-2 and bearing the legend set forth in Section
2.06(g)(iii) hereof), which shall be deposited on behalf of the purchasers of
the Notes represented thereby with the Trustee, at its New York office, as
custodian for the Depositary, and registered in the name of the Depositary or
the nominee of the Depositary for the accounts of designated agents holding
on behalf of Euroclear or Cedel Bank, duly executed by the Company and
authenticated by the Trustee as hereinafter provided.  The Restricted Period

                                       24

<PAGE>

shall be terminated upon the receipt by the Trustee of (i) a written
certificate from the Depositary, together with copies of certificates from
Euroclear and Cedel Bank certifying that they have received certification of
non-United States beneficial ownership of 100% of the aggregate principal
amount of the Regulation S Temporary Global Note (except to the extent of any
beneficial owners thereof who acquired an interest therein during the
Restricted Period pursuant to another exemption from registration under the
Securities Act and who will take delivery of a beneficial ownership interest in
a 144A Global Note or an IAI Global Note, all as contemplated by Section
2.06(a)(ii) hereof), and (ii) an Officers' Certificate from the Company.
Following the termination of the Restricted Period, beneficial interests in the
Regulation S Temporary Global Note shall be exchanged for beneficial interests
in Regulation S Permanent Global Notes pursuant to the Applicable Procedures.
Simultaneously with the authentication of Regulation S Permanent Global Notes,
the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate
principal amount of the Regulation S Temporary Global Note and the Regulation S
Permanent Global Notes may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depositary or its
nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

          The provisions of the "Operating Procedures of the Euroclear System"
and "Terms and Conditions Governing Use of Euroclear" and the "General Terms
and Conditions of Cedel Bank" and "Customer Handbook" of Cedel Bank shall be
applicable to interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by the Agent Members through
Euroclear or Cedel Bank.

Section 2.02.  Execution and Authentication.

          Two Officers shall sign the Notes for the Company by manual or
facsimile signature. The Company's seal shall be reproduced on the Notes and
may be in facsimile form.

          If an Officer whose signature is on a Note no longer holds that
office at the time a Note is authenticated, the Note shall nevertheless be
valid.

          A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

          The Trustee shall, upon a written order of the Company signed by two
Officers, authenticate Notes for original issue up to the aggregate principal
amount stated in paragraph 4 of the Notes. The aggregate principal amount of
Notes outstanding at any time may not exceed such amount except as provided in
Section 2.07 hereof.

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

                                       25

Section 2.03.  Registrar and Paying Agent.

          The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent"). The
Registrar shall keep a register of the Notes and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrar and
the term "Paying Agent" includes any additional paying agent. The Company may
change any Paying Agent or Registrar without notice to any Holder. The Company
shall notify the Trustee in writing of the name and address of any Agent not a
party to this Indenture. If the Company fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such. The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.

          The Company initially appoints The Depository Trust Company ("DTC")
to act as Depositary with respect to the Global Notes.

          The Company initially appoints the Trustee to act as the Registrar
and Paying Agent and to act as Note Custodian with respect to the Global Notes.

Section 2.04.  Paying Agent to Hold Money in Trust.

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Company in making any such
payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent.
Upon any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Notes.

Section 2.05.  Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee
is not the Registrar, the Company shall furnish to the Trustee at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Company shall otherwise comply with TIA Section 312(a).

Section 2.06.  Transfer and Exchange.

          (a)  Transfer and Exchange of Global Notes.  A Global Note may not
be transferred as a whole except by the Depositary to a nominee of the

                                       26

<PAGE>

Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Notes will be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 120 days after the date of
such notice from the Depositary or (ii) the Company in its sole discretion
determines that the Global Notes (in whole but not in part) should be exchanged
for Definitive Notes and delivers a written notice to such effect to the
Trustee; provided that in no event shall the Regulation S Temporary Global Note
be exchanged by the Company for Definitive Notes prior to (x) the expiration of
the Restricted Period and (y) the receipt by the Registrar of any certificates
required pursuant to Rule 903 under the Securities Act. Upon the occurrence of
either of the preceding events in (i) or (ii) above, Definitive Notes shall be
issued in such names as the Depositary shall instruct the Trustee. Global Notes
also may be exchanged or replaced, in whole or in part, as provided in Sections
2.07 and 2.11 hereof. Every Note authenticated and made available for delivery
in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant
to Section 2.07 or 2.11 hereof, shall be authenticated and made available for
delivery in the form of, and shall be, a Global Note. A Global Note may not be
exchanged for another Note other than as provided in this Section 2.06(a),
however beneficial interests in a Global Note may be transferred and exchanged
as provided in Section 2.06(b), (c) or (f) hereof.

          (b) Transfer and Exchange of Beneficial Interests in the Global
Notes. The transfer and exchange of beneficial interests in the Global Notes
shall be effected through the Depositary, in accordance with the provisions of
this Indenture and the procedures of the Depositary therefor. Beneficial
interests in the Restricted Global Notes shall be subject to restrictions on
transfer comparable to those set forth herein to the extent required by the
Securities Act. The Trustee shall have no obligation to ascertain the
Depositary's compliance with any such restrictions on transfer. Transfers of
beneficial interests in the Global Notes also shall require compliance with
either subparagraph (i) or (ii) below, as applicable, as well as one or more of
the other following subparagraphs as applicable:

          (i) Transfer of Beneficial Interests in the Same Global Note.
     Beneficial interests in any Restricted Global Note may be transferred to
     Persons who take delivery thereof in the form of a beneficial interest in
     the same Restricted Global Note in accordance with the transfer
     restrictions set forth in the Private Placement Legend; provided, however,
     that prior to the expiration of the Restricted Period transfers of
     beneficial interests in the Temporary Regulation S Global Note may not be
     made to a U.S. Person or for the account or benefit of a U.S. Person
     (other than an Initial Purchaser). Beneficial interests in any
     Unrestricted Global Note may be transferred only to Persons who take
     delivery thereof in the form of a beneficial interest in an Unrestricted
     Global Note. No written orders or instructions shall be required to be
     delivered to the Registrar to effect the transfers described in this
     Section 2.06(b)(i).

         (ii)  All Other Transfers and Exchanges of Beneficial Interests in
     Global Notes.  In connection with all transfers and exchanges of
     beneficial interests (other than transfers of beneficial interests in a

                                       27

<PAGE>

     Global Note to Persons who take delivery thereof in the form of a
     beneficial interest in the same Global Note), the transferor of such
     beneficial interest must deliver to the Registrar either (A) (1) a written
     order from a Participant or an Indirect Participant given to the
     Depositary in accordance with the Applicable Procedures directing the
     Depositary to credit or cause to be credited a beneficial interest in the
     specified Global Note in an amount equal to the beneficial interest to be
     transferred or exchanged and (2) instructions given in accordance with the
     Applicable Procedures containing information regarding the Participant
     account to be credited with such increase or (B) (1) a written order from
     a Participant or an Indirect Participant given to the Depositary in

     cause to be issued a Definitive Note in an amount equal to the beneficial
     interest to be transferred or exchanged and (2) instructions given by the
     Depositary to the Registrar containing information regarding the Person in
     whose name such Definitive Note shall be registered to effect the transfer
     ore exchange referred to in (1) above; provided that in no event shall
     Definitive Notes be issued upon the transfer or exchange of beneficial
     interests in the Regulation S Temporary Global Note prior to (x) the
     expiration of the Restricted Period and (y) the receipt by the Registrar
     of any certificates required pursuant to Rule 903 under the Securities
     Act. Upon an Exchange Offer by the Company in accordance with Section
     2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be
     deemed to have been satisfied upon receipt by the Registrar of the
     instructions contained in the Letter of Transmittal delivered by the
     Holder of such beneficial interests in the Restricted Global Notes. Upon
     satisfaction of all of the requirements for transfer or exchange of
     beneficial interests in Global Notes contained in this Indenture, the
     Notes and otherwise applicable under the Securities Act, the Trustee shall
     adjust the principal amount of the relevant Global Note(s) pursuant to
     Section 2.06(h) hereof.

        (iii) Transfer of Beneficial Interests to Another Restricted Global
     Note. Beneficial interests in any Restricted Global Note may be
     transferred to Persons who take delivery thereof in the form of a
     beneficial interest in another Restricted Global Note if the Registrar
     receives the following:

               (A) if the transferee will take delivery in the form of a
          beneficial interest in the 144A Global Note, then the transferor must
          deliver a certificate in the form of Exhibit B hereto, including the
          certifications in item (1) thereof;

          deliver (x) a certificate in the form of Exhibit B hereto, including
          the certifications in item (3) thereof, (y) to the extent required by
          item 3(d) of Exhibit B hereto, an Opinion of Counsel in form
          reasonably acceptable to the Company to the effect that such transfer
          is in compliance with the Securities Act and such beneficial interest
          is being transferred in compliance with any

          requirements of the Securities Act other than Rule 144A under the
          Securities Act, Rule 144 under the Securities Act or Rule 904 under
          the Securities Act, a certificate from the transferee in the form of

     or transferred to Persons who take delivery thereof in the form of a
     beneficial interest in the Unrestricted Global Note if:

          Person who is an affiliate (as defined in Rule 144) of the Company;

          Dealer pursuant to the Exchange Offer Registration Statement in

               (D) the Registrar receives the following:

                    (1) if the holder of such beneficial interest in a
          Restricted Global Note proposes to exchange such beneficial interest
          for a beneficial interest in the Unrestricted Global Note, a
          certificate from such holder in the form of Exhibit C hereto,
          including the certifications in item (1)(a) thereof;

                    (2) if the holder of such beneficial interest in a

     NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL
     BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON."


          (h) Cancellation and/or Adjustment of Global Notes. At such time as
all beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
cancelled in whole and not in part, each such Global Note shall be returned to
or retained and cancelled by the Trustee in accordance with Section 2.11
hereof. At any time prior to such cancellation, if any beneficial interest in a
Global Note is exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Note or for
Definitive Notes, the principal amount of Notes represented by such Global Note
shall be reduced accordingly and an endorsement shall be made on such Global
Note, by the Trustee or by the Depositary at the direction of the Trustee, to
reflect such reduction; and if the beneficial interest is being exchanged for
or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note, such other Global Note shall be
increased accordingly and an endorsement shall be made on such Global Note, by
the Trustee or by the Depositary at the direction of the Trustee, to reflect
such increase.

          (i)  General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Company
     shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon the Company's order or at the Registrar's request.

         (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 4.10, 4.15 and 9.05 hereof).

        (iii) The Registrar shall not be required to register the transfer of
     or exchange any Note selected for redemption in whole or in part, except
     the unredeemed portion of any Note being redeemed in part.

                                       38

<PAGE>

         (iv) All Global Notes and Definitive Notes issued upon any
     registration of transfer or exchange of Global Notes or Definitive Notes
     shall be the valid obligations of the Company, evidencing the same debt,
     and entitled to the same benefits under this Indenture, as the Global
     Notes or Definitive Notes surrendered upon such registration of transfer
     or exchange.

          (v) The Company shall not be required (A) to issue, to register the
     transfer of or to exchange Notes during a period beginning at the opening
     of business 15 days before the day of any selection of Notes for
     redemption under Section 3.02 hereof and ending at the close of business
     on the day of selection, (B) to register the transfer of or to exchange
     any Note so selected for redemption in whole or in part, except the
     unredeemed portion of any Note being redeemed in part or (C) to register
     the transfer of or to exchange a Note between a record date and the next
     succeeding Interest Payment Date.

         (vi) Prior to due presentment for the registration of a transfer of
     any Note, the Trustee, any Agent and the Company may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of and interest on
     such Notes and for all other purposes, and none of the Trustee, any Agent
     or the Company shall be affected by notice to the contrary.

        (vii) The Trustee shall authenticate Global Notes and Definitive Notes
     in accordance with the provisions of Section 2.02 hereof.

Section 2.07.  Replacement Notes.

          If any mutilated Note is surrendered to the Trustee, or the Company
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Note, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate
a replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company, an indemnity bond must be supplied by the Holder that
is sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Note is replaced. The Company may charge for its
expenses in replacing a Note.

          Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

Section 2.08.  Outstanding Notes.

          The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note.

                                       39

<PAGE>

          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to
be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

          If the principal amount of any Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

          If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

Section 2.09.  Treasury Notes.

          In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company, shall be
considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that a Trustee knows are so owned
shall be so disregarded.

Section 2.10.  Temporary Notes.

          Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon a written order
of the Company signed by two Officers of the Company. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Notes in exchange for
temporary Notes.

          Holders of temporary Notes shall be entitled to all of the benefits
of this Indenture.

Section 2.11.  Cancellation.

          The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee and no one else shall cancel all Notes surrendered for registration
of transfer, exchange, payment, replacement or cancellation and shall destroy
cancelled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all cancelled Notes shall be
delivered to the Company. The Company may not issue new Notes to replace Notes
that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12.  Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are

                                       40

<PAGE>

Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee
in writing of the amount of defaulted interest proposed to be paid on each Note
and the date of the proposed payment. The Company shall fix or cause to be
fixed each such special record date and payment date, provided that no such
special record date shall be less than 10 days prior to the related payment
date for such defaulted interest. At least 15 days before the special record
date, the Company (or, upon the written request of the Company, the Trustee in
the name and at the expense of the Company) shall mail or cause to be mailed to
Holders a notice that states the special record date, the related payment date
and the amount of such interest to be paid.

Section 2.13.  CUSIP Numbers.

          The Company in issuing the Notes may use CUSIP numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption
and that reliance may be placed only on the other identification numbers
printed on the Notes, and any such redemption shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the
Trustee of any change in the CUSIP numbers.

                           REDEMPTION AND PREPAYMENT

Section 3.01.  Notices to Trustee.

          If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant
to which the redemption shall occur, (ii) the redemption date, (iii) the
principal amount of Notes to be redeemed and (iv) the redemption price.

Section 3.02.  Selection of Notes to Be Redeemed.

          If less than all of the Notes are to be redeemed at any time,
selection of Notes for redemption shall be made by the Trustee in compliance
with the requirements of the principal national securities exchange, if any, on
which the Notes are listed, or, if the Notes are not so listed, on a pro rata
basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided that no Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Notes to be redeemed at its
registered address. Notices of redemption may not be conditional. If any Note
is to be redeemed in part only, the notice of redemption that relates to such
Note shall state the portion of the principal amount thereof to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof shall be
issued in the name of the Holder thereof upon cancellation of the original
Note. Notes called for redemption become due on the date fixed for redemption.
On and after the redemption date, interest ceases to accrue on Notes or
portions of them called for redemption.

          The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for

                                       41

<PAGE>

partial redemption, the principal amount thereof to be redeemed. Notes and
portions of Notes selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

Section 3.03.  Notice of Redemption.

          Subject to the provisions of Section 3.09 hereof, at least 30 days
but not more than 60 days before a redemption date, the Company shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Notes are to be redeemed at its registered address.

          The notice shall identify the Notes to be redeemed (including CUSIP
Numbers, if any) and shall state:

          (a)  the redemption date;

          (b)  the redemption price;

          (c) if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the
     redemption date upon surrender of such Note, a new Note or Notes in
     principal amount equal to the unredeemed portion shall be issued upon
     cancellation of the original Note;

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

          (e)  that Notes called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (f) that, unless the Company defaults in making such redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the redemption date;

          (g)  the paragraph of the Notes and/or Section of this Indenture
     pursuant to which the Notes called for redemption are being redeemed;
     and

          (h) that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on the
     Notes.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that
the Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph.

Section 3.04.  Effect of Notice of Redemption.

          Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the

                                       42

<PAGE>

redemption date at the redemption price.  A notice of redemption may not be
conditional.

Section 3.05.  Deposit of Redemption Price.

          Prior to 11:00 a.m. on the Business Day prior to the redemption date,
the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest on all Notes to
be redeemed on that date. The Trustee or the Paying Agent shall promptly return
to the Company any money deposited with the Trustee or the Paying Agent by the
Company in excess of the amounts necessary to pay the redemption price of, and
accrued interest on, all Notes to be redeemed.

          If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof.

Section 3.06.  Notes Redeemed in Part.

          Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

Section 3.07.  Optional Redemption.

          (a) Except as set forth in clause (b) of this Section 3.7, the Notes
shall not be redeemable at the Company's option prior to May 1, 2002.
Thereafter, the Notes shall be subject to redemption at any time at the option
of the Company, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages
thereon, if any, to the applicable redemption date, if redeemed during the
twelve-month period beginning on May 1 of the years indicated below:

            Year                                       Percentage
            ----                                       ----------
            2002  . . . . . . . . . . . . . . . . .    105.188%
            2003  . . . . . . . . . . . . . . . . .    103.458%

            2005 and thereafter   . . . . . . . . .    100.000%

          (b) Notwithstanding the foregoing clause (a), during the first 36
months after the Issue Date, the Company may on any one or more occasions
redeem up to an aggregate of 35% of the Notes originally issued at a redemption
price of 109.375% of the principal amount thereof, plus accrued and unpaid
interest and Liquidated Damages thereon, if any, to the redemption

                                       43

<PAGE>

date, with the net cash proceeds of one or more Equity Offerings by the Company
or the net cash proceeds of one or more Equity Offerings by Holdings that are
contributed to the Company as common equity capital; provided that at least 65%
of the Notes originally issued remain outstanding immediately after the
occurrence of each such redemption; and provided, further, that any such
redemption must occur within 120 days of the date of the closing of such Equity
Offering.

Section 3.08.  Mandatory Redemption.

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

Section 3.09.  Offer to Purchase by Application of Excess Proceeds.

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

          The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

          If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Company shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

               (a) that the Asset Sale Offer is being made pursuant to this
     Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale
     Offer shall remain open;

               (b)  the Offer Amount, the purchase price and the Purchase
     Date;

               (c)  that any Note not tendered or accepted for payment shall
     continue to accrete or accrue interest;

               (d) that, unless the Company defaults in making such payment,
     any Note accepted for payment pursuant to the Asset Sale Offer shall cease
     to accrete or accrue interest after the Purchase Date;

                                       44

<PAGE>

               (e) that Holders electing to have a Note purchased pursuant to
     an Asset Sale Offer may only elect to have all of such Note purchased and
     may not elect to have only a portion of such Note purchased;

               (f) that Holders electing to have a Note purchased pursuant to
     any Asset Sale Offer shall be required to surrender the Note, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Note completed, or transfer by book-entry transfer, to the Company, a
     depositary, if appointed by the Company, or a Paying Agent at the address
     specified in the notice at least three days before the Purchase Date;

               (g) that Holders shall be entitled to withdraw their election if
     the Company, the depositary or the Paying Agent, as the case may be,
     receives, not later than the expiration of the Offer Period, a facsimile
     transmission or letter setting forth the name of the Holder, the principal
     amount of the Note the Holder delivered for purchase and a statement that
     such Holder is withdrawing his election to have such Note purchased;

               (h) that, if the aggregate principal amount of Notes surrendered
     by Holders exceeds the Offer Amount, the Company shall select the Notes to
     be purchased on a pro rata basis (with such adjustments as may be deemed
     appropriate by the Company so that only Notes in denominations of $1,000,
     or integral multiples thereof, shall be purchased); and

               (i) that Holders whose Notes were purchased only in part shall
     be issued new Notes equal in principal amount to the unpurchased portion
     of the Notes surrendered (or transferred by book-entry transfer).

          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 3.09. The Company, the Depositary or
the Paying Agent, as the case may be, shall promptly (but in any case not later
than five days after the Purchase Date) mail or deliver to each tendering
Holder an amount equal to the purchase price of the Notes tendered by such
Holder and accepted by the Company for purchase, and the Company shall promptly
issue a new Note, and the Trustee, upon written request from the Company shall
authenticate and mail or deliver such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered. Any Note not
so accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company shall publicly announce the results of the Asset Sale
Offer on the Purchase Date.

          Other than as specifically provided in this Section 3.09, any
purchase pursuant to this Section 3.09 shall be made pursuant to the provisions
of Sections 3.01 through 3.06 hereof.

          The Company shall pay or cause to be paid the principal of, premium,
if any, and interest on the Notes on the dates and in the manner provided in
the Notes. Principal, premium, if any, and interest shall be considered paid on
the date due if the Paying Agent, if other than the Company or a Subsidiary
thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. The Company shall
pay all Liquidated Damages, if any, in the same manner on the dates and in the
amounts set forth in the Registration Rights Agreement.

          The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal at the applicable
interest rate on the Notes to the extent lawful; it shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law)
on overdue installments of interest and Liquidated Damages (without regard to
any applicable grace period) at the same rate to the extent lawful.

Section 4.02.  Maintenance of Office or Agency.

          The Company shall maintain in the Borough of Manhattan, The City of
New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may
be served. The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee.

          The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

          The Company hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section
2.03.

Section 4.03.  Reports.

          Whether or not required by the rules and regulations of the
Securities and Exchange Commission (the "Commission"), so long as any Notes are
outstanding, the Company shall furnish to the Holders of Notes:

                                       46

<PAGE>

     required to be contained in a filing with the Commission on Forms 10-Q and
     10-K if the Company were required to file such Forms, including a
     "Management's Discussion and Analysis of Financial Condition and Results
     of Operations" that describes the financial condition and results of
     operations of the Company and its consolidated Subsidiaries (showing in
     reasonable detail, either on the face of the financial statements or in
     the footnotes thereto and in Management's Discussion and Analysis of
     Financial Condition and Results of Operations, the financial condition and
     results of operations of the Company and its Restricted Subsidiaries
     separately from the financial condition and results of operations of the
     Unrestricted Subsidiaries of the Company) and, with respect to the annual
     information only, a report thereon by the Company's certified independent
     accountants, and

          (b) all current reports that would be required to be filed with the
     Commission on Form 8-K if the Company were required to file such reports,
     in each case within the time periods specified in the Commission's rules
     and regulations.

          In addition, whether or not required by the rules and regulations of
the Commission, following the consummation of the Exchange Offer contemplated
by the Registration Rights Agreement, the Company shall file a copy of all such
information and reports with the Commission for public availability within the
time periods set forth in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available
to securities analysts and prospective investors upon request. In addition, the
Company and the Subsidiary Guarantors have agreed that, for so long as any
Notes remain outstanding and are required to bear the Private Placement Legend,
they shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act.

          Subject to the provisions of Article 7, delivery of such reports,
information and documents to the Trustee is for informational proposes only and
the Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

Section 4.04.  Compliance Certificate.

          (a) The Company shall deliver to the Trustee, within 90 days after
the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Company and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained
in this Indenture and is not in default in the performance or observance of any
of the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with

                                       47

<PAGE>

respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action the Company is taking
or proposes to take with respect thereto.

          (b) So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by
a written statement of the Company's independent public accountants (who shall
be a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

          (c) The Company shall, so long as any of the Notes are outstanding,
deliver to the Trustee, as soon as possible and in any event within five
Business Days after any Officer becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with
respect thereto.

Section 4.05.  Taxes.

          The Company shall pay, and shall cause each of its Subsidiaries to
pay, prior to delinquency, all material taxes, assessments, and governmental
levies except such as are contested in good faith and by appropriate
proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders of the Notes.

Section 4.06.

          Intentionally omitted.

Section 4.07.  Restricted Payments.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or
make any other payment or distribution on account of the Company's or any of
its Restricted Subsidiaries' Equity Interests (including, without limitation,
any payment in connection with any merger or consolidation involving the
Company) or to the direct or indirect holders of the Company's or any of its
Restricted Subsidiaries' Equity Interests in their capacity as such (other than
(A) dividends or distributions payable in Equity Interests (other than
Disqualified Stock) of the Company or (B) dividends or distributions by a
Restricted Subsidiary so long as, in the case of any dividend or distribution
payable on or in respect of any class or series of securities issued by a
Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, the
Company or a Restricted Subsidiary receives at least its pro rata share of such
dividend or distribution in accordance with its Equity Interests in such class
or series of securities); (ii) purchase, redeem or otherwise acquire or retire
for value (including without limitation, in connection with any merger or
consolidation involving the Company) any Equity Interests of the Company

                                       48

<PAGE>

or any direct or indirect parent of the Company; (iii) make any payment on or
with respect to, or purchase, redeem, defease or otherwise acquire or retire
for value any Indebtedness that is subordinated to the Notes except a payment
of interest or principal at Stated Maturity; or (iv) make any Restricted
Investment (all such payments and other actions set forth in clauses (i)
through (iv) above being collectively referred to as "Restricted Payments"),
unless, at the time of and after giving effect to such Restricted Payment:

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

          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have
     been permitted to incur at least $1.00 of additional Indebtedness pursuant
     to the Fixed Charge Coverage Ratio test set forth in the first paragraph
     of Section 4.09; and

          (c) such Restricted Payment, together with the aggregate amount of
     all other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the Issue Date (excluding Restricted Payments permitted
     by clauses (ii) through (vii) of the next succeeding paragraph), 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 the beginning of the
     first fiscal quarter commencing after the Issue Date to the end of the
     Company's most recently ended fiscal quarter for which internal financial
     statements are available at the time of such Restricted Payment (or, if
     such Consolidated Net Income for such period is a deficit, less 100% of
     such deficit), plus (ii) 100% of the aggregate net cash proceeds received
     by the Company from a contribution to its common equity capital or the
     issue or sale since the Issue Date 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 the Issue Date is sold for cash
     or otherwise liquidated or repaid for cash, the amount of cash received in
     connection therewith (or from the sale of Marketable Securities received
     in connection therewith), plus (iv) to the extent not already included in
     such Consolidated Net Income of the Company for such period and without
     duplication, (A) 100% of the aggregate amount of cash received as a
     dividend from an Unrestricted Subsidiary, (B) 100% of the cash received
     upon the sale of Marketable Securities received as a dividend from an
     Unrestricted Subsidiary, and (C) 100% of the net assets of any
     Unrestricted Subsidiary on the date that it becomes a Restricted
     Subsidiary.

     The foregoing provisions shall not prohibit: (i) the payment of any
dividend within 60 days after the date of declaration thereof, if at said date
of declaration such payment would have complied with the provisions of this
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
in exchange for, or out of the net cash proceeds of the substantially
concurrent sale (other than to a Subsidiary of the Company) of, other Equity

                                       49

<PAGE>

Interests of the Company (other than any Disqualified Stock); provided that the
amount of any such net cash proceeds that are utilized for any such redemption,
repurchase, retirement, defeasance or other acquisition shall be excluded from
clause (c) (ii) of the preceding paragraph; (iii) the defeasance, redemption,
repurchase or other acquisition of subordinated Indebtedness (other than
intercompany Indebtedness) in exchange for, or with the net cash proceeds from
an incurrence of, Permitted Refinancing Indebtedness; (iv) the repurchase,
retirement or other acquisition or retirement for value of common Equity
Interests of the Company or Holdings held by any future, present or former
employee, director or consultant of the Company or any Subsidiary or Holdings
issued pursuant to any management equity plan or stock option plan or any other
management or employee benefit plan or agreement; provided, however, that the
aggregate amount of Restricted Payments made under this clause (iv) does not
exceed $1.5 million in any calendar year and provided further that cancellation
of Indebtedness owing to the Company from members of management of the Company
or any of its Restricted Subsidiaries in connection with a repurchase of Equity
Interests of the Company shall not be deemed to constitute a Restricted Payment
for purposes of this covenant or any other provision of this Indenture; (v)
repurchases of Equity Interests deemed to occur upon exercise of stock options
upon surrender of Equity Interests to pay the exercise price of such options;
(vi) payments to Holdings (A) in amounts equal to the amounts required for
Holdings to pay franchise taxes and other fees required to maintain its legal
existence and provide for other operating costs of up to $500,000 per fiscal
year and (B) in amounts equal to amounts required for Holdings to pay federal,
state and local income taxes to the extent such income taxes are actually due
and owing; provided that the aggregate amount paid under this clause (B) does
not exceed the amount that the Company would be required to pay in respect of
the income of the Company and its Subsidiaries if the Company were a stand
alone entity that was not owned by Holdings; and (vii) other Restricted
Payments in an aggregate amount since the Issue Date not to exceed $20.0
million.

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

          The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined by the
Board of Directors whose resolution with respect thereto shall be delivered to
the Trustee. Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by Section 4.07 were computed.

               Subsidiaries.

          The Company shall not, and shall not permit any of its Restricted

exist or become effective any encumbrance or restriction on the ability of any

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

Company or any of its Restricted Subsidiaries as in effect at the time of such

with or in contemplation of such acquisition), which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person, so acquired,
provided that, in the case of Indebtedness, such Indebtedness was permitted by
the terms of this Indenture to be incurred, (F) by reason of customary
non-assignment provisions in leases entered into in the ordinary course of
business and consistent with past practices, (G) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions
of the nature described in this clause (iii) on the property so acquired, (H)
Permitted Refinancing Indebtedness, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are no more
restrictive than those contained in the agreements governing the Indebtedness
being refinanced, (I) contracts for the sale of assets, including, without
limitation, customary restrictions with respect to a Subsidiary pursuant to an
agreement that has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Subsidiary, (J)

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.

     The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect
to (collectively, "incur") any Indebtedness (including Acquired Debt) and that
the Company shall not issue any Disqualified Stock and shall not permit any of
its Subsidiaries to issue any shares of preferred stock; provided, however,
that the Company and any Restricted Subsidiary may incur Indebtedness
(including Acquired Debt) or issue shares of preferred stock if the Fixed
Charge Coverage Ratio for the Company's most recently ended four

                                       51

<PAGE>

full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is
incurred or such preferred stock is issued would have been at least 2.0 to 1.0,
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred, or
the preferred stock had been issued, as the case may be, at the beginning of
such four-quarter period.

          The provisions of the first paragraph of this Section 4.09 shall not
apply to the incurrence of any of the following items of Indebtedness
(collectively, "Permitted Debt"):

          (i) the incurrence by the Company of term Indebtedness under Credit

     the aggregate principal amount of all term Indebtedness outstanding under
     all Credit Facilities after giving effect to such incurrence, including
     all Permitted Refinancing Indebtedness incurred to refund, refinance or
     replace any other Indebtedness incurred pursuant to this clause (i), does
     not exceed an amount equal to $175.0 million less the aggregate amount of

     and letters of credit (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) under Credit Facilities (and
     the guarantee thereof by the Guarantors); provided that the aggregate
     principal amount of all revolving credit Indebtedness outstanding under
     all Credit Facilities after giving effect to such incurrence, including
     all Permitted Refinancing Indebtedness incurred to refund, refinance or
     replace any other Indebtedness incurred pursuant to this clause (ii), does
     not exceed an amount equal to $100.0 million less the aggregate amount of
     all Net Proceeds of Asset Sales applied to repay any such Indebtedness
     (including any such Permitted Refinancing Indebtedness) pursuant to

     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
     incurred to refund, refinance or replace any other Indebtedness incurred
     pursuant to this clause (v), not to exceed $30.0 million at any time

<PAGE>

     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 (vi), does not exceed $10.0
     million;

        (vii) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the

     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;

         (ix) 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

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

          (x) 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;

                                       53

<PAGE>

         (xi) 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

     Indebtedness of the Company or a Restricted Subsidiary of the Company that
     was permitted to be incurred by another provision of this Section
     4.09;

       (xiii) 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 (xiii),
     and the issuance of preferred stock by Unrestricted Subsidiaries;

        (xiv)  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

         (xv) 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 incurred to refund, refinance or
     replace any other Indebtedness incurred pursuant to this clause (xv), not
     to exceed $50.0 million.

          For purposes of determining compliance with this Section 4.09, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xv) above or is
entitled to be incurred pursuant to the first paragraph of this Section 4.09,
the Company shall, in its sole discretion, classify such item of Indebtedness
in any manner that complies with this covenant. Accrual of interest, the
accretion of accreted value and the payment of interest in the form of
additional Indebtedness shall not be deemed to be an incurrence of Indebtedness
for purposes of this Section 4.09.

Section 4.10.  Asset Sales.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time
of such Asset Sale at least equal to the fair market value (evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee) 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

                                       54

<PAGE>

long-term assets that are used or useful in one or more Similar Businesses and
(3) Permitted Securities shall be deemed to be cash for purposes of this
provision.

          Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option, (i) to repay
Indebtedness under a Credit Facility, or (ii) to the acquisition of Permitted
Securities, all or substantially all of the assets of one or more Similar
Businesses, or the making of a capital expenditure or the acquisition of other
long-term assets in a Similar Business. Pending the final application of any
such Net Proceeds, the Company may temporarily reduce Indebtedness under a
Credit Facility or otherwise invest such Net Proceeds in any manner that is not
prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not
applied or invested as provided in the first sentence of this paragraph shall
be deemed to constitute "Excess Proceeds". When the aggregate amount of Excess
Proceeds exceeds $10.0 million, the Company shall be required to make an offer
to all Holders of Notes (an "Asset Sale Offer") to purchase the maximum
principal amount of Notes that may be purchased out of the Excess Proceeds, at
an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest and Liquidated Damages thereon, if
any, to the date of purchase, in accordance with the procedures set forth in
this Indenture. To the extent that the aggregate amount of Notes tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company
may use any remaining Excess Proceeds for general corporate purposes. If the
aggregate principal amount of Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes to be purchased
on a pro rata basis. Upon completion of such offer to purchase, the amount of
Excess Proceeds shall be reset at zero.

Section 4.11.  Transactions with Affiliates.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless
(i) such Affiliate Transaction is on terms that are no less favorable to the
Company or the relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (ii) the Company delivers to the
Trustee (A) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $3.0
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 $10.0 million, an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing.

          The foregoing provisions shall not prohibit: (i) any employment
agreement entered into by the Company or any of its Restricted Subsidiaries in
the ordinary course of business; (ii) any transaction with a Lehman

                                       55

<PAGE>

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, 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 $1.0 million but less than $25.0 million, such transaction or series
of transactions (or the agreement pursuant to which the transactions were
executed) was approved by the Company's Chief Executive Officer or Chief
Financial Officer and (B) in the case of any such transaction or series of
related transactions pursuant to this clause (iv) involving aggregate
consideration equal to or in excess of $25.0 million, such transaction or
series of related transactions (or the agreement pursuant to which the
transactions were executed) was approved by a majority of the disinterested
members of the Board of Directors; (v) any transaction pursuant to and in
accordance with the provisions of the Transaction Documents as the same are in
effect on the Issue Date; and (vi) any Restricted Payment that is permitted by
the provisions of Section 4.07.

Section 4.12.  Liens.

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

Section 4.13.  Future Subsidiary Guarantees

          If the Company or any of its Subsidiaries shall acquire or create a
Subsidiary (other than a Foreign Subsidiary or an Unrestricted Subsidiary)
after the Issue Date, then such Subsidiary shall execute a Subsidiary
Guarantee, in the form of the Supplemental Indenture attached hereto as Exhibit
E, and the Form of Notation on Senior Subordinated Note, attached hereto as
Exhibit F, and deliver an opinion of counsel as to the validity of such
Subsidiary Guarantee, in accordance with the terms of this Indenture. The
Subsidiary Guarantee of each Guarantor will be subordinated to the prior
payment in full of all Senior Debt of such Guarantor, which would include the
guarantees of amounts borrowed under the Senior Credit Facilities. The
obligations of each Guarantor under its Subsidiary Guarantee will be limited so
as not to constitute a fraudulent conveyance under applicable law.

          No Guarantor may consolidate with or merge with or into (whether or
not such Guarantor is the surviving Person) another Person (except the Company
or another Guarantor) unless (i) subject to the provisions of the following
paragraph, the Person formed by or surviving any such consolidation or merger
(if other than such Guarantor) or to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of such Guarantor pursuant to a supplemental indenture in form and
substance reasonably satisfactory to the Trustee, under the Notes and this
Indenture; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; (iii) the Company (A) would be permitted by virtue
of the Company's pro forma Fixed Charge Coverage Ratio, immediately after
giving effect to such transaction, to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test

                                       56

<PAGE>

set forth in Section 4.09 or (B) would have a pro forma Fixed Charge Coverage
Ratio that is greater than the actual Fixed Charge Coverage Ratio for the same
four-quarter period without giving pro forma effect to such transaction.

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

          In the event of a sale or other disposition of all of the assets of
any Guarantor, by way of merger, consolidation or otherwise, or a sale or other
disposition of all of the capital stock of any Guarantor, then such Guarantor
(in the event of a sale or other disposition, by way of such a merger,
consolidation or otherwise, of all of the capital stock of such Guarantor) or
the corporation acquiring the property (in the event of a sale or other
disposition of all of the assets of such Guarantor) will be released and
relieved of any obligations under its Subsidiary Guarantee; provided that the
Net Proceeds of such sale or other disposition are applied in accordance with
the applicable provisions of Section 4.10.


Section 4.14.  Corporate Existence.

          Subject to Article 5 hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any such Restricted Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and its Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Restricted Subsidiaries, if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and its Restricted Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

Section 4.15.  Offer to Repurchase Upon Change of Control.

          (a) Upon the occurrence of a Change of Control, each Holder of Notes
shall have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
date of purchase (the "Change of Control Payment"). Within ten days following
any Change of Control, the Company shall mail a notice to each Holder
describing the transaction or transactions that constitute the Change of
Control and offering to repurchase Notes on the date specified in such notice,
which date shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the "Change of Control Payment Date"). Such notice,
which shall govern the terms of the Change of Control offer, shall state: (i)
that the Change of Control Offer is being made pursuant to

                                       57

<PAGE>

this Section 4.15 and that all Notes tendered will be accepted for payment;
(ii) the purchase price and the purchase date; (iii) that any Note not tendered
will continue to accrue interest; (iv) that, unless the Company defaults in the
payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest after
the Change of Control Payment Date; (v) that Holders electing to have any Notes
purchased pursuant to a Change of Control Offer will be required to surrender
the Notes, with the form entitled "Option of Holder to Elect Purchase" on the
reverse of the Notes completed, to the Paying Agent at the address specified in
the notice prior to the close of business on the third Business Day preceding
the Change of Control Payment Date; (vi) that Holders will be entitled to
withdraw their election if the Paying Agent receives, not later than the close
of business on the second Business Day preceding the Change of Control Payment
Date, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of Notes delivered for purchase, and a
statement that such Holder is withdrawing his election to have the Notes
purchased; and (vii) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered, which unpurchased portion must be equal to $1,000 in
principal amount or an integral multiple thereof. The Company shall comply with
the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws and regulations are
applicable in connection with the repurchase of Notes in connection with a
Change of Control.

          (b) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (i) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so tendered and (iii) deliver or cause to be delivered to
the Trustee the Notes so accepted together with an Officers' Certificate
stating the aggregate principal amount of Notes or portions thereof being
purchased by the Company. The Paying Agent shall promptly mail to each Holder
of Notes so tendered the Change of Control Payment for such Notes, and the
Trustee shall promptly authenticate and mail (or cause to be transferred by
book entry) to each Holder a new Note equal in principal amount to any
unpurchased portion of the Notes surrendered, if any; provided that each such
new Note shall be in a principal amount of $1,000 or an integral multiple
thereof. Prior to mailing a Change of Control Offer, but in any event within 90
days following a Change of Control, the Company shall either repay all
outstanding Senior Debt or offer to repay all Senior Debt and terminate all
commitments thereunder of each lender who has accepted such offer or obtain the
requisite consents, if any, under all agreements governing outstanding Senior
Debt to permit the repurchase of Notes required by this Section 4.15. The
Company shall publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date.

Section 4.16.  No Senior Subordinated Debt.

          The Company shall not incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Senior Debt and senior in any respect in right of
payment to the Notes. No Guarantor shall incur, create, issue, assume,
guarantee or otherwise become liable for any Indebtedness that is subordinate

                                       58

<PAGE>

or junior in right of payment to any Senior Debt of a Guarantor and senior in
any respect in right of payment to any of the Subsidiary Guarantees.

Section 4.17.  Payments for Consent.

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

Section 5.01.  Merger, Consolidation, or Sale of Assets.

          The Company may not consolidate or merge with or into (whether or not
the Company is the surviving corporation), or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets in one or more related transactions, to another corporation, Person or
entity unless (i) the Company is the surviving corporation or the entity or the
Person formed by or surviving any such consolidation or merger (if other than
the Company) or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made is a corporation organized or existing
under the laws of the United States, any state thereof or the District of
Columbia; (ii) the entity or Person formed by or surviving any such
consolidation or merger (if other than the Company) or the entity or Person to
which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made assumes all the obligations of the Company under the Notes
and this Indenture pursuant to a supplemental indenture in a form reasonably
satisfactory to the Trustee; (iii) immediately after such transaction no
Default or Event of Default exists; and (iv) except in the case of a merger of
the Company with or into a Wholly Owned Restricted Subsidiary of the Company,
the Company or the entity or Person formed by or surviving any such
consolidation or merger (if other than the Company), or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made, after giving pro forma effect to such transaction as if such transaction
had occurred at the beginning of the most recently ended four full fiscal
quarters for which internal financial statements are available immediately
preceding such transaction either (A) would be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the first paragraph of Section 4.09 or (B) would have a pro
forma Fixed Charge Coverage Ratio that is greater than the actual Fixed Charge
Coverage Ratio for the same four-quarter period without giving pro forma effect
to such transaction.

          Notwithstanding clause (iv) in the immediately foregoing paragraph,
(i) any Restricted Subsidiary may consolidate with, merge into or transfer all
or part of its properties and assets to the Company and (ii) the Company may
merge with an Affiliate that has no significant assets or liabilities and was
incorporated solely for the purpose of reincorporating the Company in

                                       59

<PAGE>

another State of the United States so long as the amount of Indebtedness of the
Company and its Restricted Subsidiaries is not increased thereby.

Section 5.02.  Successor Corporation Substituted.

          Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the
assets of the Company in accordance with Section 5.01 hereof, the successor
corporation formed by such consolidation or into or with which the Company is
merged or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), and may
exercise every right and power of the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the
obligation to pay the principal of and interest on the Notes except in the case
of a sale of all of the Company's assets that meets the requirements of Section
5.01 hereof.


                                  ARTICLE 6
                            DEFAULTS AND REMEDIES

          (e) a default occurs under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Restricted Subsidiaries), whether such Indebtedness or guarantee now
exists, or is created after the date of this Indenture, which default results
in the acceleration of such Indebtedness prior to its express maturity and, in
each case, the principal amount of such Indebtedness, together with the
principal amount of any other such Indebtedness, together with the principal

                                       60

<PAGE>

amount of any other such Indebtedness, the maturity of which has been so
accelerated, aggregates $10.0 million or more;

          (g) the Company or any of its Significant Subsidiaries or any group
of Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary pursuant to or within the meaning of Bankruptcy Law:

          (i)  commences a voluntary case,

         (ii)  consents to the entry of an order for relief against it in an
     involuntary case,

        (iii)  consents to the appointment of a Custodian of it or for all or
     substantially all of its property,

         (iv)  makes a general assignment for the benefit of its creditors,
     or

          (v)  generally is not paying its debts as they become due;

          (h) a court of competent jurisdiction enters an order or decree under
any Bankruptcy Law that:

          (i) is for relief against the Company or any of its Significant
     Subsidiaries or any group of Subsidiaries that, taken as a whole, would
     constitute a Significant Subsidiary in an involuntary case;

         (ii) appoints a Custodian of the Company or any of its Significant
     Subsidiaries or any group of Subsidiaries that, taken as a whole, would
     constitute a Significant Subsidiary or for all or substantially all of the

     group of Subsidiaries that, taken as a whole, would constitute a
     Significant Subsidiary; or

     consecutive days; or

          (i) Except as permitted herein, any Subsidiary Guarantee shall be
held in any judicial proceeding to be unenforceable or invalid.

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

                                       61

Section 6.02.  Acceleration.

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

          In the case of any Event of Default occurring by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding payment of the premium that the Company
would have had to pay if the Company then had elected to redeem the Notes
pursuant to the optional redemption provisions of this Indenture, an equivalent
premium shall also become and be immediately due and payable to the extent
permitted by law upon the acceleration of the Notes. If an Event of Default
occurs prior to May 1, 2002 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 1, 2002, then the
premium specified below shall also become immediately due and payable to the
extent permitted by law upon the acceleration of the Notes during the
twelve-month period ending on May 1 of the years indicated below:

            Year                                       Percentage
            ----                                       ----------
            1997  . . . . . . . . . . . . . . . . .    115.562%
            1998  . . . . . . . . . . . . . . . . .    113.833%
            1999  . . . . . . . . . . . . . . . . .    112.104%
            2000  . . . . . . . . . . . . . . . . .    110.375%
            2001  . . . . . . . . . . . . . . . . .    108.646%
            2002  . . . . . . . . . . . . . . . . .    106.917%

Section 6.03.  Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and interest on the Notes or to enforce the performance of any provision
of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. All remedies
are cumulative to the extent permitted by law.

                                       62

<PAGE>

Section 6.04.  Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the
Holders of all of the Notes waive an existing Default or Event of Default and
its consequences hereunder, except a continuing Default or Event of Default in
the payment of the principal of, premium and Liquidated Damages, if any, or
interest on, the Notes (including in connection with an offer to purchase)
(provided, however, that the Holders of a majority in aggregate principal
amount at maturity of the then outstanding Notes may rescind an acceleration
and its consequences, including any related payment default that resulted from
such acceleration). Upon any such waiver, such Default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

Section 6.06.  Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture

receipt of the request and the offer and, if requested, the provision of
indemnity; and

          (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

respective dates, shall not be impaired or affected without the consent of such
Holder.

custodian in any such judicial proceeding is hereby authorized by each Holder

consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the

reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

Section 7.01.  Duties of Trustee.

          (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

          (i) the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

         (ii) in the absence of bad faith or negligence on its part, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture. However, the Trustee shall examine the certificates and
     opinions to determine whether or not they conform to the requirements of

                                       65

<PAGE>

     this Indenture (but need not confirm or investigate the accuracy of
     mathematical calculations or other facts stated therein).

          (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

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

     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05 hereof.

this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section.

expend or risk its own funds or incur any liability. The Trustee shall be under

the request of any Holders, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability
or expense.

received by it except as the Trustee may agree in writing with the Company.

an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall
not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may
consult with counsel and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection from liability

rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities

default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Notes and this Indenture.

          (i) Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company.

Section 7.03.  Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with
like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11

paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be

                                       67

<PAGE>

the case of a Default or Event of Default in payment of principal of, premium,
if any, or interest on any Note, the Trustee may withhold the notice if and so
long as a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of the Holders of the Notes.

Section 7.06.  Reports by Trustee to Holders of the Notes.

          Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports
as required by TIA Section 313(c).

exchange on which the Notes are listed in accordance with TIA Section 313(d).
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

          The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred
or made by it in addition to the compensation for its services. Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

          The Company shall indemnify the Trustee or any predecessor Trustee
against any and all losses, liabilities or expenses incurred by it arising out
of or in connection with the acceptance or administration of its duties under
this Indenture, including the costs and expenses of enforcing this Indenture
against the Company (including this Section 7.07) and defending itself against
any claim (whether asserted by the Company or any Holder or any other person)
or liability in connection with the exercise or performance of any of its
powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company
of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable fees and expenses of such counsel. The
Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld.

and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 7.07, except with respect to funds held in

Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and

discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

Section 7.08.  Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's

office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office,
the Holders of a majority in principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

          If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Notes of at least 10% in principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

          If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note may petition any court of competent

                                       69

<PAGE>

jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

corporation, the successor corporation without any further act shall be the
successor Trustee.

Section 7.10.  Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or
state authorities and that has a combined capital and surplus of at least $50
million as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

Section 7.11.  Preferential Collection of Claims Against Company.

Section 8.02.  Legal Defeasance and Discharge.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall
be deemed to have paid and discharged the entire Indebtedness represented by
the outstanding Notes, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 8.05 hereof and the other Sections of this
Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of outstanding Notes to receive solely from the trust fund described in
Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (b) the Company's obligations with respect to such Notes
under Sections 2.06, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and the Company's
obligations in connection therewith and (d) this Article 8. Subject to
compliance with this Article 8, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof.

Section 8.03.  Covenant Defeasance.

          Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15
and 4.16 and Article 5 hereof with respect to the outstanding Notes on and
after the date the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"), and the Notes shall thereafter be deemed not
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Notes shall not be deemed outstanding
for accounting purposes). For this purpose, Covenant Defeasance means that,
with respect to the outstanding Notes, the Company may omit to comply with and
shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference
in any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 6.01 hereof, but, except as specified above, the remainder of
this Indenture and such Notes shall be unaffected thereby. In addition, upon
the Company's exercise under Section 8.01 hereof of the option applicable to
this Section 8.03 hereof, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not
constitute Events of Default.

for the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be

applicable federal income tax law, in either case to the effect that, and based

hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound;

          (f) the Company shall have delivered to the Trustee an opinion of
counsel to the effect that on the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,

                                       72

insolvency, reorganization or similar laws affecting creditors' rights
generally;

          (g) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders over any other creditors of the Company or
with the intent of defeating, hindering, delaying or defrauding any other
creditors of the Company; and

          (h) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

Section 8.05.  Deposited Money and Government Securities to be Held in Trust;
               Other Miscellaneous Provisions.

          Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent
required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the
outstanding Notes.

          Anything in this Article 8 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

Section 8.06.  Repayment to Company.

          Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium, if
any, or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as a
secured creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof,

                                       73

<PAGE>

shall thereupon cease; provided, however, that the Trustee or such Paying
Agent, before being required to make any such repayment, may at the expense of
the Company cause to be published once, in the New York Times and The Wall
Street Journal (national edition), notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

Section 8.07.  Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02
or 8.03 hereof, as the case may be, by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
8.02 or 8.03 hereof, as the case may be; provided, however, that, if the
Company makes any payment of principal of, premium, if any, or interest on any
Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.


                                  ARTICLE 9
                       AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of Notes.

          Notwithstanding Section 9.02 of this Indenture, the Company and the
Trustee may amend or supplement this Indenture or the Notes without the consent
of any Holder of a Note:

          (a)  to cure any ambiguity, defect or inconsistency;

          (b)  to provide for uncertificated Notes in addition to or in place
of certificated Notes;

          (c)  to provide for the assumption of the Company's obligations to
the Holders of the Notes in the case of a merger or consolidation pursuant to
Article 5 hereof;

          (d) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the
legal rights hereunder of any Holder of the Note; or

          (e) to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA.

          Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company in
the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be

                                       74

<PAGE>

obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

Section 9.02.  With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10
and 4.15 hereof) and the Notes may be amended or supplemented with the consent
of the Holders of at least a majority in principal amount of the Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange offer for the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, or interest on the
Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes (including consents obtained in connection with a
tender offer or exchange offer for the Notes).

          Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee shall join with the Company in the execution
of such amended or supplemental Indenture unless such amended or supplemental
Indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to consent to any indenture
supplemental hereto. If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided, that unless such consent shall
have become effective by virtue of the requisite percentage having been
obtained prior to the date which is 180 days after such record date, any such
consent previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.

          It shall not be necessary for the consent of the Holders of Notes
under this Section 9.02 to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Notes. However, without the consent

                                       75

<PAGE>

of each Holder affected, an amendment or waiver may not (with respect to any
Notes held by a non-consenting Holder):

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

          (b) reduce the principal of or change the fixed maturity of any Note
or alter or waive any of the provisions with respect to the redemption of the
Notes except as provided above with respect to Sections 4.10 and 4.15 hereof;

          (c)  reduce the rate of or change the time for payment of interest,
including default interest, on any Note;

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

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

          (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of or interest on the Notes; or

          (g) waive a redemption payment with respect to any Note (other than a
payment required by Sections 3.09, 4.10 and 4.15 hereof).

          (h) make any change in Section 6.04 or 6.07 hereof or in the
foregoing amendment and waiver provisions.

Section 9.03.  Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

Section 9.04.  Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment
becomes effective. An amendment, supplement or waiver becomes effective in
accordance with its terms and thereafter binds every Holder.

Section 9.05.  Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated.  The Company in

                                       76

<PAGE>

exchange for all Notes may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall
not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06.  Trustee to Sign Amendments, etc.

          The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01) shall be
fully protected in relying upon, an Officer's Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.


                                  ARTICLE 10
                                 SUBORDINATION

Section 10.01. Agreement to Subordinate.

          The Company agrees, and each Holder by accepting a Note agrees, that
the Indebtedness evidenced by the Notes is subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
in full of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for
the benefit of the holders of Senior Debt.

Section 10.02. Liquidation; Dissolution; Bankruptcy.

          Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities, the holders of Senior Debt shall be entitled to receive
payment in full in cash of all Obligations due in respect of such Senior Debt
(including interest after the commencement of any such proceeding at the rate
specified in the applicable Senior Debt, whether or not an allowable claim in
any such proceeding) before the Holders of Notes will be entitled to receive
any payment with respect to the Notes, and until all Obligations with respect
to Senior Debt are paid in full, any distribution to which the Holders of Notes
would be entitled shall be made to the holders of Senior Debt (except, in each
case, that Holders of Notes may receive Permitted Junior Securities and
payments made from the trust described under Article 8).

Section 10.03. Default on Designated Senior Debt.

          The Company may not make any payment or distribution to the Trustee
or any Holder in respect of Obligations with respect to the Notes and may not
acquire from the Trustee or any Holder any Notes for cash or property (other
than (i) securities that are subordinated to at least the same extent as the
Notes to (a) Senior Indebtedness and (b) any securities issued in exchange

                                       77

<PAGE>

for Senior Indebtedness and (ii) payments and other distributions made from any
defeasance trust created pursuant to Section 8.01 hereof) until all principal
and other Obligations with respect to the Senior Indebtedness have been paid in
full if:

          (i) a default in the payment of any principal or other Obligations
     with respect to Designated Senior Indebtedness occurs and is continuing
     beyond any applicable grace period in the agreement, indenture or other
     document governing such Designated Senior Indebtedness; or

         (ii) a default, other than a payment default, on Designated Senior
     Indebtedness occurs and is continuing that then permits holders of the
     Designated Senior Indebtedness to accelerate its maturity and the Trustee
     receives a notice of the default (a "Payment Blockage Notice") from a
     Representative with respect to such Designated Senior Debt. If the Trustee
     receives any such Payment Blockage Notice, no subsequent Payment Blockage
     Notice shall be effective for purposes of this Section unless and until
     (i) at least 365 days shall have elapsed since the effectiveness of the
     immediately prior Payment Blockage Notice and (ii) all scheduled payments
     of principal, premium, if any, and interest on the Notes that have come
     due have been paid in full in cash. No nonpayment default that existed or
     was continuing on the date of delivery of any Payment Blockage Notice to
     the Trustee shall be, or be made, the basis for a subsequent Payment
     Blockage Notice unless such default shall have been waived or cured for a
     period of not less than 180 days.

          The Company may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

          (1)  the date upon which the default is cured or waived, or

          (2) in the case of a default referred to in Section 10.03(ii) hereof,
     179 days pass after notice is received if the maturity of such Designated
     Senior Indebtedness has not been accelerated,

if this Article otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

Section 10.04. Acceleration of Securities.

          If payment of the Securities is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Debt of the
acceleration.

Section 10.05. When Distribution Must Be Paid Over.

          In the event that the Trustee or any Holder receives any payment of
any Obligations with respect to the Notes at a time when the Trustee or such
Holder, as applicable, has actual knowledge that such payment is prohibited by
Article 10 hereof, such payment shall be held by the Trustee or such Holder, in
trust for the benefit of, and shall be paid forthwith over and delivered, upon
written request, to, the holders of Senior Debt as their interests may appear
or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of all Obligations with
respect to Senior Debt remaining unpaid to the extent

                                       78

<PAGE>

necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders
of Senior Debt.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically
set forth in this Article 10, and no implied covenants or obligations with
respect to the holders of Senior Debt shall be read into this Indenture against
the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt shall
be entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or negligence of the Trustee.

Section 10.06. Notice by Company.

          The Company shall promptly notify the Trustee and the Paying Agent of
any facts known to the Company that would cause a payment of any Obligations
with respect to the Notes to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt as
provided in this Article 10.

          The Trustee shall be entitled to rely on the delivery to it of a
written notice by a person representing himself to be a holder of Senior
Indebtedness (or a trustee or agent on behalf of such holder) to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee or
agent on behalf of any such holder). In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of
any person as holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article 10, the Trustee may request such person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Senior Indebtedness held by such person, the extent to which such
person is entitled to participate in such evidence is not furnish, the Trustee
may defer any payment which it may be required to make for the benefit of such
person pursuant to the terms of this Indenture pending judicial determination
as to the rights of such person to receive such payment.

Section 10.07. Subrogation.

          After all Senior Debt is paid in full and until the Notes are paid in
full, Holders of Notes shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt
to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders of Notes have been applied to
the payment of Senior Debt. A distribution made under this Article 10 to
holders of Senior Debt that otherwise would have been made to Holders of Notes
is not, as between the Company and Holders, a payment by the Company on the
Notes.

Section 10.08. Relative Rights.

          This Article 10 defines the relative rights of Holders of Notes and
holders of Senior Debt. Nothing in this Indenture shall:

                                       79

<PAGE>

          (1) impair, as between the Company and Holders of Notes, the
     obligation of the Company, which is absolute and unconditional, to pay
     principal of and interest on the Notes in accordance with their terms;

          (2) affect the relative rights of Holders of Notes and creditors of
     the Company other than their rights in relation to holders of Senior Debt;
     or

          (3) prevent the Trustee or any Holder of Notes from exercising its
     available remedies upon a Default or Event of Default, subject to the
     rights of holders and owners of Senior Debt to receive distributions and
     payments otherwise payable to Holders of Notes.

          If the Company fails because of this Article 10 to pay principal of
or interest on a Note on the due date, the failure is still a Default or Event
of Default.

Section 10.09. Subordination May Not Be Impaired by Company.

          No right of any holder of Senior Debt to enforce the subordination of
the Indebtedness evidenced by the Notes shall be impaired by any act or failure
to act by the Company or any Holder or by the failure of the Company or any
Holder to comply with this Indenture.

Section 10.10. Distribution or Notice to Representative.

          Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

          Upon any payment or distribution of assets of the Company referred to
in this Article 10, the Trustee and the Holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Holders
of Notes for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of the Senior Debt and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
10.

Section 10.11. Rights of Trustee and Paying Agent.

          Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least three Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Notes to violate this Article 10. Only the Company or a
Representative may give the notice. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07
hereof.

                                       80

<PAGE>

          The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee.  Any Agent
may do the same with like rights.

Section 10.12. Authorization to Effect Subordination.

          Each Holder of Notes, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the credit agents are hereby authorized to file an appropriate
claim for and on behalf of the Holders of the Notes.

Section 10.13. Amendments.

          The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of at least 75% in aggregate
principal amount of the Notes then outstanding if such amendment would
adversely affect the rights of Holders of Notes.

Section 11.03. Communication by Holders of Notes with Other Holders of Notes.

          Holders may communicate pursuant to TIA Section 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The
Company, the Trustee, the Registrar and anyone else shall have the protection
of TIA Section 312(c).

satisfactory to the Trustee (which shall include the statements set forth in
Section 11.05 hereof) stating that, in the opinion of the signers, all
conditions precedent and covenants, if any, provided for in this Indenture
relating to the proposed action have been satisfied; and

          (b) an Opinion of Counsel in form and substance reasonably

Section 11.05. Statements Required in Certificate or Opinion.

          Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than a certificate
provided pursuant to TIA Section 314(a)(4)) shall comply with the provisions of
TIA Section 314(e) and shall include:

          (a)  a statement that the Person making such certificate or opinion
has read such covenant or condition;

          (b) a brief statement as to the nature and scope of the examination
or investigation upon which the statements or opinions contained in such
certificate or opinion are based;

          (c) a statement that, in the opinion of such Person, he or she has
made such examination or investigation as is necessary to enable him to express
an informed opinion as to whether or not such covenant or condition has been
satisfied; and

          (d) a statement as to whether or not, in the opinion of such Person,

Section 11.06. Rules by Trustee and Agents.

          The Trustee may make reasonable rules for action by or at a meeting

Company, as such, shall have any liability for any obligations of the Company
under the Notes and this Indenture or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

TO CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES, WITHOUT

Indenture.

Section 11.11. Severability.

          In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

     1. Interest. L-3 Communications Corporation, a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 10
3/8% per annum from April 30, 1997 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Company will pay interest and Liquidated Damages, if
any, semi-annually on May 1 and November 1 of each year, or if any such day is
not a Business Day, on the next succeeding Business Day (each an "Interest
Payment Date"), with the same force and effect as if made on the date for such
payment. Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be November 1, 1997. The
Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue principal and premium, if any, from time
to time on demand at the rate then in effect to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

     2. Method of Payment. The Company will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the April 15 or October 15 next
(whether or not a Business Day) preceding the Interest Payment Date, even if
such Notes are cancelled after such record date and on or before such Interest
Payment Date, except as provided in Section 2.12 of the Indenture with respect
to defaulted interest. The Notes will be payable as to principal, premium and
Liquidated Damages, if any, and interest at the office or agency of the Company
maintained for such purpose within The City and State of New York, or, at the
option of the Company, payment of interest and Liquidated Damages may be made
by check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and interest, premium and
Liquidated Damages on, all Global Notes and all other Notes the Holders of
which shall have provided wire transfer instructions to the Company or the
Paying Agent if such Holders shall be registered Holders of at least $250,000
in principal amount of the Notes. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

     3.  Paying Agent and Registrar.  Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar.  The
Company may change any Paying Agent or Registrar without notice to any
Holder.  The Company or any of its Subsidiaries may act in any such capacity.

     4.  Indenture.  The Company issued the Notes under an Indenture dated as
of April 30, 1997 ("Indenture") between the Company and the Trustee.  The
terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939, as amended
(15 U.S. Code Sections 77aaa-77bbbb).  The Notes are subject to all such

                                       89

<PAGE>

terms, and Holders are referred to the Indenture and such Act for a statement
of such terms. To the extent any provision of this Note conflicts with the
express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Notes are obligations of the Company limited to
$225.0 million in aggregate principal amount, plus amounts, if any, issued to
pay Liquidated Damages on outstanding Notes as set forth in Paragraph 2 hereof.

     5.  Optional Redemption.

          (a) Except as set forth in clause (b) of this paragraph 5, the Notes
shall not be redeemable at the Company's option prior to May 1, 2002.
Thereafter, the Notes shall be subject to redemption at any time at the option
of the Company, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages
thereon, if any, to the applicable redemption date, if redeemed during the
twelve-month period beginning on May 1 of the years indicated below:

            Year                                       Percentage
            ----                                       ----------
            2002  . . . . . . . . . . . . . . . . .    105.188%
            2003  . . . . . . . . . . . . . . . . .    103.458%
            2004    . . . . . . . . . . . . . . . .    101.729%
            2005 and thereafter   . . . . . . . . .    100.000%

          (b) Notwithstanding the foregoing, during the first 36 months after
the date of the Indenture, the Company may on any one or more occasions redeem
up to an aggregate of 35% of the Notes originally issued at a redemption price
of 109.375% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages thereon, if any, to the redemption date, with the net
cash proceeds of one or more Equity Offerings by the Company or the net cash
proceeds of one or more Equity Offerings by Holdings that are contributed to
the Company as common equity capital; provided that at least 65% of the Notes
originally issued remain outstanding immediately after the occurrence of each
such redemption; and provided, further, that any such redemption must occur
within 120 days of the date of the closing of such Equity Offering.

     6.  Mandatory Redemption.

     Except as set forth in paragraph 7 below, the Company shall not be
required to make mandatory redemption payments with respect to the Notes.

     7.  Repurchase at Option of Holder.

     (a) If there is a Change of Control, the Company shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of aggregate principle amount thereof plus accrued and
unpaid interest, if any, to the date of purchase (in either case, the "Change
of Control Payment"). Within 10 days following any Change of Control, the
Company shall mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture.

                                       90

<PAGE>

     (b) If the Company or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess
Proceeds exceeds $10.0 million, the Company shall commence an offer to all
Holders of Notes (as "Asset Sale Offer") pursuant to Section 3.09 of the
Indenture to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% thereof on the date fixed for the closing of such offer or 100%
of the principal amount thereof plus accrued and unpaid interest, if any, to
the date fixed for the closing of such offer, in accordance with the procedures
set forth in the Indenture. To the extent that the aggregate amount of Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Subsidiary) may use such deficiency for general corporate
purposes. If the aggregate principal amount of Notes surrendered by Holders
thereof exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

     8. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions
thereof called for redemption.

     9. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided
in the Indenture. The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and
the Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date
and the corresponding Interest Payment Date.

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

     11. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such

                                       91

<PAGE>

Holder, or to comply with the requirements of the Commission in order to effect
or maintain the qualification of the Indenture under the Trust Indenture Act.

     12. Defaults and Remedies. An "Event of Default" occurs if: (i) default
for 30 days in the payment when due of interest on, or Liquidated Damages with
respect to, the Notes (whether or not prohibited by the subordination
provisions of the Indenture); (ii) default in payment when due of the principal
of or premium, if any, on the Notes (whether or not prohibited by the
subordination provisions of the Indenture); (iii) failure by the Company to
comply with the covenants contained in sections 4.10, 4.15 or 5.10 of the
Indenture; (iv) failure by the Company for 60 days after notice to comply with
any of its other agreements in the Indenture or the Notes; (v) default under
any mortgage, indenture or instrument under which there may be issued or by
which there may be secured or evidenced any Indebtedness for money borrowed by
the Company or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries) whether such
Indebtedness or guarantee now exists, or is created after the Issue Date, which
default results in the acceleration of such Indebtedness prior to its express
maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness the maturity
of which has been so accelerated, aggregates $10.0 million or more; (vi)
failure by the Company or any of its Restricted Subsidiaries to pay final
judgments aggregating in excess of $10.0 million, which judgments are not paid,
discharged or stayed for a period of 60 days; (vii) certain events of
bankruptcy or insolvency with respect to the Company or any of its Significant
Subsidiaries; and (viii) except as permitted by the Indenture, any Subsidiary
Guarantee shall be held in any judicial proceeding to be unenforceable or
invalid.

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

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

                                       92

<PAGE>

prior to May 1, 2002 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 1, 2002, then the premium
specified in the Indenture shall also become immediately due and payable to the
extent permitted by law upon the acceleration of the Notes.

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

     13. Trustee Dealings with Company. The Trustee, in its individual or any

for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

     14. No Recourse Against Others. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

     15.  Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

     17. Additional Rights of Holders of Transfer Restricted Securities. In
addition to the rights provided to Holders of Notes under the Indenture,
Holders of Transferred Restricted Securities shall have all the rights set
forth in the A/B Exchange Registration Rights Agreement dated as of April 30,
1997, between the Company and the parties named on the signature pages thereof
(the "Registration Rights Agreement").

     18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     19. The internal law of the State of New York shall govern and be used to
construe this Note, without regard to the principles of conflicts of laws.

<PAGE>

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. Interest. L-3 Communications Corporation, a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 10
3/8% per annum from April 30, 1997 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Company will pay interest and Liquidated Damages, if
any, semi-annually on May 1 and November 1 of each year, or if any such day is
not a Business Day, on the next succeeding Business Day (each an "Interest
Payment Date"), with the same force and effect as if made on the date for such
payment. Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be November 1, 1997. The
Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue principal and premium, if any, from time
to time on demand at the rate then in effect to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

          Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Senior Subordinated Notes under the Indenture.

     2. Method of Payment. The Company will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the April 15 or October 15
(whether or not a Business Day) next preceding the Interest Payment Date, even
if such Notes are cancelled after such record date and on or before such
Interest Payment Date, except as provided in Section 2.12 of the Indenture with
respect to defaulted interest. The Notes will be payable as to principal,
premium, interest and Liquidated Damages at the office or agency of the Company
maintained for such purpose within The City and State of New York, or, at the
option of the Company, payment of interest and Liquidated Damages may be made
by check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and interest, premium and
Liquidated Damages on, all Global Notes and all other Notes the Holders of
which shall have provided wire transfer instructions to the Company or the
Paying Agent if such Holders shall be registered Holders of at least $25,000 in
principal amount of the Notes. Such payment shall be in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts.

                                      100

<PAGE>

     3.  Paying Agent and Registrar.  Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar.  The
Company may change any Paying Agent or Registrar without notice to any
Holder.  The Company or any of its Subsidiaries may act in any such capacity.

     4. Indenture. The Company issued the Notes under an Indenture dated as of
April 30, 1997 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and
be controlling. The Notes are obligations of the Company limited to $225.0
million in aggregate principal amount, plus amounts, if any, issued to pay
Liquidated Damages on outstanding Notes as set forth in Paragraph 2 hereof.

     5.  Optional Redemption.

          The Notes shall not be redeemable at the Company's option prior to
May 1, 2002. Thereafter, the Notes shall be subject to redemption at any time
at the option of the Company, in whole or in part, upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages
of principal amount) set forth below plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on May 1 of the years
indicated below:

            Year                                       Percentage
            ----                                       ----------
            2002  . . . . . . . . . . . . . . . . .    105.188%
            2003  . . . . . . . . . . . . . . . . .    103.458%
            2004    . . . . . . . . . . . . . . . .    101.729%
            2005 and thereafter   . . . . . . . . .    100.000%

          Notwithstanding the foregoing, during the first 36 months after the
date of the Indenture, the Company may on any one or more occasions redeem up
to an aggregate of 35% of the Notes originally issued at a redemption price of
109.375% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the redemption date, with the net cash
proceeds of one or more Equity Offerings by the Company or the net cash
proceeds of one or more Equity Offerings by Holdings that are contributed to
the Company as common equity capital; provided that at least 65% of the Notes
originally issued remain outstanding immediately after the occurrence of each
such redemption; and provided, further, that any such redemption must occur
within 120 days of the date of the closing of such Equity Offering.

     6.  Mandatory Redemption.

     Except as set forth in paragraph 7 below, the Company shall not be
required to make mandatory redemption payments with respect to the Notes.

     7.  Repurchase at Option of Holder.

     (a) If there is a Change of Control, the Company shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part

                                      101

<PAGE>

(equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a
purchase price equal to 101% thereof on the date of purchase or 101% of the
aggregate principal amount at maturity thereof plus accrued and unpaid
interest, if any, to the date of purchase (in either case, the "Change of
Control Payment"). Within 10 days following any Change of Control, the Company
shall mail a notice to each Holder setting forth the procedures governing the
Change of Control Offer as required by the Indenture.

     (b) If the Company or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess
Proceeds exceeds $10.0 million, the Company shall commence an offer to all
Holders of Notes (as "Asset Sale Offer") pursuant to Section 3.09 of the
Indenture to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% thereof on the date fixed for the closing of such offer or 100%
of the principal amount thereof plus accrued and unpaid interest, if any, to
the date fixed for the closing of such offer, in accordance with the procedures
set forth in the Indenture. To the extent that the aggregate amount of Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Subsidiary) may use such deficiency for general corporate
purposes. If the aggregate principal amount of Notes surrendered by Holders
thereof exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

     8. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions
thereof called for redemption.

     9. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000.
The transfer of Notes may be registered and Notes may be exchanged as provided
in the Indenture. The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and
the Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date
and the corresponding Interest Payment Date.

          This Regulation S Temporary Global Note is exchangeable in whole or
in part for one or more Global Notes only (i) on or after the termination of
the 40-day restricted period (as defined in Regulation S) and (ii) upon
presentation of certificates (accompanied by an Opinion of Counsel, if
applicable) required by Article 2 of the Indenture. Upon exchange of this
Regulation S Temporary Global Note for one or more Global Notes, the Trustee
shall cancel this Regulation S Temporary Global Note.

                                      102

<PAGE>

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

     11. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act.

     12. Defaults and Remedies. An "Event of Default" occurs if: (i) default
for 30 days in the payment when due of interest on, or Liquidated Damages with
respect to, the Notes (whether or not prohibited by the subordination
provisions of the Indenture); (ii) default in payment when due of the principal
of or premium, if any, on the Notes (whether or not prohibited by the
subordination provisions of the Indenture); (iii) failure by the Company to
comply with the covenants contained in sections 4.10, 4.15 or 5.10 of the
Indenture; (iv) failure by the Company for 60 days after notice to comply with
any of its other agreements in the Indenture or the Notes; (v) default under
any mortgage, indenture or instrument under which there may be issued or by
which there may be secured or evidenced any Indebtedness for money borrowed by
the Company or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries) whether such
Indebtedness or guarantee now exists, or is created after the Issue Date, which
default results in the acceleration of such Indebtedness prior to its express
maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness the maturity
of which has been so accelerated, aggregates $10.0 million or more; (vi)
failure by the Company or any of its Restricted Subsidiaries to pay final
judgments aggregating in excess of $10.0 million, which judgments are not paid,
discharged or stayed for a period of 60 days; (vii) certain events of
bankruptcy or insolvency with respect to the Company or any of its Significant
Subsidiaries; and (viii) except as permitted by the Indenture, any Subsidiary
Guarantee shall be held in any judicial proceeding to be unenforceable or
invalid.

     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately; provided, however,
that so long as any Designated Senior Debt is outstanding, such declaration
shall not become effective until the earlier of (i) the day which is five
Business Days after receipt by the Representatives of Designated Senior Debt of
such notice of acceleration or (ii) the date of acceleration of any Designated
Senior Debt. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, with respect to the
Company or any Restricted Subsidiary, all outstanding

                                      103

<PAGE>

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
1, 2002 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 1, 2002, 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

risk of our or its investment.

          5. We are acquiring the Notes or Book-Entry Interests purchased by us

  Form of Supplemental Indenture to Be Delivered by Guaranteeing Subsidiary



          Supplemental Indenture (this "Supplemental Indenture"), dated as of
________________, between __________________ (the "Guaranteeing Subsidiary"), a
subsidiary of L-3 Communications Corporation (or its permitted successor), a
Delaware corporation (the "Company"), and The Bank of New York, as trustee
under the indenture referred to below (the "Trustee").

                              W I T N E S S E T H

          WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (the "Indenture"), dated as of April 30, 1997 providing
for the issuance of an aggregate principal amount of up to $225,000,000 of
10 3/8% Senior Notes due 2007 (the "Notes");

          WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Subsidiary Guarantee"); and

          WHEREAS, pursuant to Section 4.13 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

          NOW THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

     1.   Capitalized Terms.  Capitalized terms used herein without
definition shall have the meanings assigned to them in the Indenture.

     2.   Agreement to Guarantee.  The Guaranteeing Subsidiary hereby agrees
as follows:

          (a)  The Guaranteeing Subsidiary, jointly and severally with all
               other Guaranteeing Subsidiaries, if any, unconditionally
               guarantees to each Holder of a Senior Note authenticated and
               delivered by the Trustee and to the Trustee and its successors
               and assigns, regardless of the validity and enforceability of
               the Indenture, the Notes or the Obligations of the Company under
               the Indenture or the Notes, that:

          (i)  the principal of, premium and interest on the Notes will be
               promptly paid in full when due, whether at maturity, by
               acceleration, redemption or otherwise, and interest on the
               overdue principal of, premium and interest on the Notes, to
               the extent lawful, and all other Obligations of the Company to
               the Holders or the Trustee thereunder or under the Indenture
               will be promptly paid in full, all in accordance with the
               terms thereof; and

                                      119

<PAGE>

          (ii) in case of any extension of time for payment or renewal of any
               Notes or any of such other Obligations, that the same will be
               promptly paid in full when due in accordance with the terms of
               the extension or renewal, whether at stated maturity, by
               acceleration or otherwise.

          (b)  Notwithstanding the foregoing, in the event that this Subsidiary
               Guarantee would constitute or result in a violation of any
               applicable fraudulent conveyance or similar law of any relevant
               jurisdiction, the liability of the Guaranteeing Subsidiary under
               this Supplemental Indenture and its Subsidiary Guarantee shall
               be reduced to the maximum amount permissible under such
               fraudulent conveyance or similar law.

     3.   Execution and Delivery of Subsidiary Guarantees.

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

          (b)  Notwithstanding the foregoing, the Guaranteeing Subsidiary
               hereby agrees that its Subsidiary Guarantee set forth herein
               shall remain in full force and effect notwithstanding any
               failure to endorse on each Senior Note a notation of such
               Subsidiary Guarantee.

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

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

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

          (f)  The Guaranteeing Subsidiary hereby waives diligence,
               presentment, demand of payment, filing of claims with a court in
               the event of insolvency or bankruptcy of the Company, any right
               to require a proceeding first against the Company, protest,
               notice and all demands whatsoever and covenants that

                                      120

<PAGE>

               its Subsidiary Guarantee made pursuant to this Supplemental
               Indenture will not be discharged except by complete performance
               of the obligations contained in the Notes and the Indenture.

          (g)  If any Holder or the Trustee is required by any court or
               otherwise to return to the Company or the Guaranteeing
               Subsidiary, or any Custodian, Trustee, liquidator or other
               similar official acting in relation to either the Company or
               the Guaranteeing Subsidiary, any amount paid by either to the
               Trustee or such Holder, the Subsidiary Guarantee made pursuant
               to this Supplemental Indenture, to the extent theretofore
               discharged, shall be reinstated in full force and effect.

          (h)  The Guaranteeing Subsidiary agrees that it shall not be entitled
               to any right of subrogation in relation to the Holders in
               respect of any obligations guaranteed hereby until payment in
               full of all obligations guaranteed hereby. The Guaranteeing
               Subsidiary further agrees that, as between the Guaranteeing
               Subsidiary, on the one hand, and the Holders and the Trustee, on
               the other hand:

               (i)  the maturity of the obligations guaranteed hereby may be
                    accelerated as provided in Article 6 of the Indenture for
                    the purposes of the Subsidiary Guarantee made pursuant to
                    this Supplemental Indenture, notwithstanding any stay,
                    injunction or other prohibition preventing such
                    acceleration in respect of the obligations guaranteed
                    hereby; and

               (ii) in the event of any declaration of acceleration of such
                    obligations as provided in Article 6 of the Indenture, such
                    obligations (whether or not due and payable) shall
                    forthwith become due and payable by the Guaranteeing
                    Subsidiary for the purpose of the Subsidiary Guarantee made
                    pursuant to this Supplemental Indenture.

          (i)  The Guaranteeing Subsidiary shall have the right to seek
               contribution from any other non-paying Guaranteeing Subsidiary
               so long as the exercise of such right does not impair the rights
               of the Holders or the Trustee under the Subsidiary Guarantee
               made pursuant to this Supplemental Indenture.

     4.   Guaranteeing Subsidiary May Consolidate, Etc. on Certain Terms.

          (a)  Except as set forth in Articles 4 and 5 of the Indenture,
               nothing contained in the Indenture, this Supplemental
               Indenture or in the Notes shall prevent any consolidation or
               merger of the Guaranteeing Subsidiary with or into the Company
               or any other Guaranteeing Subsidiary or shall prevent any
               transfer, sale or conveyance of the property of the
               Guaranteeing Subsidiary as an entirety or substantially as an
               entirety, to the Company or any other Guaranteeing Subsidiary.

          (b)  Except as set forth in Article 4 of the Indenture, nothing
               contained in the Indenture, this Supplemental Indenture or in
               the Notes shall prevent any consolidation or merger of the

                                      121

<PAGE>

               Guaranteeing Subsidiary with or into a corporation or
               corporations other than the Company or any other Guaranteeing
               Subsidiary (in each case, whether or not affiliated with the
               Guaranteeing Subsidiary), or successive consolidations or
               mergers in which a Guaranteeing Subsidiary or its successor or
               successors shall be a party or parties, or shall prevent any
               sale or conveyance of the property of a Guaranteeing Subsidiary
               as an entirety or substantially as an entirety, to a corporation
               other than the Company or any other Guaranteeing Subsidiary (in
               each case, whether or not affiliated with the Guaranteeing
               Subsidiary) authorized to acquire and operate the same;
               provided, however, that the Guaranteeing Subsidiary hereby
               covenants and agrees that (i) subject to the Indenture, upon any
               such consolidation, merger, sale or conveyance, the due and
               punctual performance and observance of all of the covenants and
               conditions of the Indenture and this Supplemental Indenture to
               be performed by such Guaranteeing Subsidiary, shall be expressly
               assumed (in the event that the Guaranteeing Subsidiary is not
               the surviving corporation in the merger), by supplemental
               indenture satisfactory in form to the Trustee, executed and
               delivered to the Trustee, by the corporation formed by such
               consolidation, or into which the Guaranteeing Subsidiary shall
               have been merged, or by the corporation which shall have
               acquired such property and (ii) immediately after giving effect
               to such consolidation, merger, sale or conveyance no Default or
               Event of Default exists.

          (c)  In case of any such consolidation, merger, sale or conveyance
               and upon the assumption by the successor corporation, by
               supplemental indenture, executed and delivered to the Trustee
               and satisfactory in form to the Trustee, of the Subsidiary
               Guarantee made pursuant to this Supplemental Indenture and the
               due and punctual performance of all of the covenants and
               conditions of the Indenture and this Supplemental Indenture to
               be performed by the Guaranteeing Subsidiary, such successor
               corporation shall succeed to and be substituted for the
               Guaranteeing Subsidiary with the same effect as if it had been
               named herein as the Guaranteeing Subsidiary; provided that,
               solely for purposes of computing Consolidated Net Income for
               purposes of clause (b) of the first paragraph of Section 4.07
               in the Indenture, the Consolidated Net Income of any Person
               other than Central Tractor Farm & Country, Inc. and its
               Restricted Subsidiaries shall only be included for periods
               subsequent to the effective time of such merger,
               consolidation, combination or transfer of assets.  Such
               successor corporation thereupon may cause to be signed any or
               all of the Subsidiary Guarantees to be endorsed upon the Notes
               issuable under the Indenture which theretofore shall not have
               been signed by the Company and delivered to the Trustee.  All
               the Subsidiary Guarantees so issued shall in all respects have
               the same legal rank and benefit under the Indenture and this
               Supplemental Indenture as the Subsidiary Guarantees
               theretofore and thereafter issued in accordance with the terms
               of the Indenture and this Supplemental Indenture as though all
               of such Subsidiary Guarantees had been issued at the date of
               the execution hereof.

     5.   Releases.

               (a) Concurrently with any sale of assets (including, if
               applicable, all of the Capital Stock of the Guaranteeing
               Subsidiary), all Liens, if any, in favor of the Trustee in the
               assets sold thereby shall be released; provided that in the
               event of an Asset Sale, the Net Proceeds from such sale or other
               disposition are treated in accordance with the provisions of
               Section 4.10 of the Indenture. If the assets sold in such sale
               or other disposition include all or substantially all of the
               assets of the Guaranteeing Subsidiary or all of the Capital
               Stock of the Guaranteeing Subsidiary, then the Guaranteeing
               Subsidiary (in the event of a sale or other disposition of all
               of the Capital Stock of such Guaranteeing Subsidiary) or the
               Person acquiring the property (in the event of a sale or other
               disposition of all or substantially all of the assets of such
               Guaranteeing Subsidiary) shall be released from and relieved of
               its obligations under this Supplemental Indenture and its
               Subsidiary Guarantee made pursuant hereto; provided that in the
               event of an Asset Sale, the Net Proceeds from such sale or other
               disposition are treated in accordance with the provisions of
               Section 4.10 of the Indenture. Upon delivery by the Company to
               the Trustee of an Officers' Certificate to the effect that such
               sale or other disposition was made by the Company or the
               Guaranteeing Subsidiary, as the case may be, in accordance with
               the provisions of the Indenture and this Supplemental Indenture,
               including without limitation, Section 4.10 of the Indenture, the
               Trustee shall execute any documents reasonably required in order
               to evidence the release of the Guaranteeing Subsidiary from its
               obligations under this Supplemental Indenture and its Subsidiary
               Guarantee made pursuant hereto. If the Guaranteeing Subsidiary
               is not released from its obligations under its Subsidiary
               Guarantee, it shall remain liable for the full amount of
               principal of and interest on the Notes and for the other
               obligations of such Guaranteeing Subsidiary under the Indenture
               as provided in this Supplemental Indenture.

               (b) Upon the designation of a Guaranteeing Subsidiary as an
               Unrestricted Subsidiary in accordance with the terms of the
               Supplemental Indenture, such Guaranteeing Subsidiary shall be
               released and relieved of its obligations under its Subsidiary
               Guarantee and this Supplemental Indenture. Upon delivery by the
               Company to the Trustee of an Officers' Certificate and an
               Opinion of Counsel to the effect that such designation of such
               Guaranteeing Subsidiary as an Unrestricted Subsidiary was made
               by the Company in accordance with the provisions of this
               Supplemental Indenture, also including without limitation
               Section 4.07 of the Indenture, the Trustee shall execute any
               documents reasonably required in order to evidence the release
               of such Guaranteeing Subsidiary from its obligations under its
               Subsidiary Guarantee. Any Guaranteeing Subsidiary not released
               from its obligations under its Subsidiary Guarantee shall remain
               liable for the full amount of principal of and interest on the
               Notes and for the other obligations of any

                                      123

<PAGE>

               Guaranteeing Subsidiary under the Indenture as provided in
               Article 10.

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

     7.   NEW YORK LAW TO GOVERN.  THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

     8. Counterparts The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

     9.   Effect of Headings.  The Section headings herein are for
convenience only and shall not affect the construction hereof.

 Form of Notation on Senior Subordinated Note Relating to Subsidiary Guarantee


          Each Guaranteeing Subsidiary (as defined in the Supplemental
Indenture (the "Supplemental Indenture") among _______________ and
_________________, (i) has jointly and severally unconditionally guaranteed (a)
the due and punctual payment of the principal of, premium and interest on the
Notes, whether at maturity or an interest payment date, by acceleration, call
for redemption or otherwise, (b) the due and punctual payment of interest on
the overdue principal and premium of, and interest on the Notes, and (c) in

other obligations, the same will be promptly paid in full when due in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise and (ii) has agreed to pay any and all
costs and expenses (including reasonable attorneys' fees) incurred by the
Trustee or any Holder in enforcing any rights under this Subsidiary Guarantee.

          Notwithstanding the foregoing, in the event that the Subsidiary
Guarantee of any Guaranteeing Subsidiary would constitute or result in a
violation of any applicable fraudulent conveyance or similar law of any
relevant jurisdiction, the liability of such Guaranteeing Subsidiary under its
Subsidiary Guarantee shall be reduced to the maximum amount permissible under
such fraudulent conveyance or similar law.

          No past, present or future director, officer, employee, agent,
incorporator, stockholder or agent of any Guaranteeing Subsidiary, as such,
shall have any liability for any obligations of the Company or any Guaranteeing
Subsidiary under the Notes, any Subsidiary Guarantee, Indenture, any
supplemental indenture delivered pursuant to the Indenture by such Guaranteeing
Subsidiary or any Subsidiary Guarantees, or for any claim based on, in respect
of or by reason of such obligations or their creation. Each Holder by accepting
a Senior Note waives and releases all such liability.

          This Subsidiary Guarantee shall be binding upon each Guaranteeing
Subsidiary and its successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any
transfer or assignment of rights by any Holder or the Trustee, the rights and
privileges herein conferred upon that party shall automatically extend to and
be vested in such transferee or assignee, all subject to the terms and
conditions hereof.

          This Subsidiary Guarantee shall not be valid or obligatory for any
purpose until the certificate of authentication on the Senior Note upon which
this Subsidiary Guarantee is noted have been executed by the Trustee under

                              EMPLOYMENT AGREEMENT

         AGREEMENT, made April 30, 1997 by and between L-3 Communications
Holdings, Inc., a Delaware corporation (the "Company") and Frank C. Lanza (the
"Executive").


                                    RECITALS


         In order to induce Executive to serve as the Chairman and Chief
Executive Officer of the Company, the Company desires to provide Executive with
compensation and other benefits on the terms and conditions set forth in this
Agreement.

         Executive is willing to accept such employment and perform services
for the Company, on the terms and conditions hereinafter set forth.

         It is therefore hereby agreed by and between the parties as follows:

         1. Employment.

         1.1 Subject to the terms and conditions of this Agreement, the Company
agrees to employ Executive during the Term hereof as its Chairman and Chief
Executive Officer. In his capacity as the Chairman and Chief Executive Officer
of the Company, Executive shall report to the Board of Directors of the Company
(the "Board") and shall have the customary powers, responsibilities and
authorities of chairmen and chief executive officers of corporations of the
size, type and nature of the Company, as it exists from time to time, and as
are assigned by the Board.

         1.2 Subject to the terms and conditions of this Agreement, Executive
hereby accepts employment as the Chairman and Chief Executive Officer of the
Company commencing as of the date hereof (the "Commencement Date") and agrees
to devote his full business time and efforts to the

                                       1

<PAGE>

performance of services, duties and responsibilities in connection therewith,
subject at all times to review and control of the Board. In addition, during
the Initial Term and any Renewal Term, (i) the Company agrees to nominate
Executive for election to the Board and use its best efforts to cause his
election to the Board and Executive agrees to serve on the Board of the Company
and (ii) during the Term of Employment, Executive also agrees to serve, if
elected, as an officer and/or director of any Subsidiary of the Company,
without the payment of any additional compensation therefor. Upon the
termination of Executive's employment for any reason, Executive shall resign as
a member of the Board of the Company or any Subsidiary of the Company.

         1.3 Nothing in this Agreement shall preclude Executive from engaging
in charitable work and community affairs, from managing any investment made by
him with respect to which Executive is not substantially involved with the
management or operation of the entity in which Executive has invested (provided
that no such investment in publicly traded equity securities or other property
may exceed 5% of the equity of any entity, without the prior approval of the
Board) or from serving, subject to the prior approval of the Board, as a member
of boards of directors or as a trustee of any other corporation, association or
entity, to the extent that any of the above activities do not materially
interfere with the performance of his duties hereunder. For purposes of the
preceding sentence, any approval by the Board required therein shall not be
unreasonably withheld.

         2. Term of Employment. Executive's term of employment under this
Agreement (the "Term of Employment") shall commence on the Commencement Date
and, subject to the terms hereof, shall terminate on the earlier of (i) the
fifth anniversary of the Commencement Date (the "Initial Term") or (ii)
termination of Executive's employment pursuant to this Agreement.
Notwithstanding the foregoing, subsequent to the Initial Term, Executive's

                                       2

<PAGE>

Term of Employment under this Agreement shall automatically renew annually for
one year renewal terms (the "Renewal Term") unless either party shall deliver
to the other written notice, at least 90 days prior to the expiration of the
Initial Term or any Renewal Term, that the Term of Employment shall not be
extended. In such event, the Term of Employment will end at its then scheduled
expiration date and shall not be further extended except by written agreement
of the Company and Executive.

         3. Compensation.

         3.1 Salary. During the Initial Term of Executive's employment under
the terms of this Agreement, the Company shall pay Executive a base salary
("Base Salary") at an initial rate of $750,000 per annum. Base Salary shall be
payable in accordance with the ordinary payroll practices of the Company.
During the Term of Employment, the Board shall, in good faith, review, at least
annually, the Executive's Base Salary in accordance with the Company's
customary procedures and practices regarding the salaries of senior executives
and may, if determined by the Board to be appropriate, increase Executive's
Base Salary following such review. Increases in the rate of salary, once
granted, shall not be subject to revocation or decrease thereafter, and "Base
Salary" for all purposes herein shall be deemed to be a reference to such
higher amount.

         4. Employee Benefits.

         4.1 Equity and Stock Options. Simultaneously with the execution of
this Agreement, the Company and Executive are entering into the Subscription
Agreement, the Option Agreement and the Stockholders' Agreement in the forms
attached hereto as Exhibits A, B and C, respectively (the "Ancillary
Documents"). Executive shall not be eligible to receive any stock option or
other equity incentive other than as set forth in the Ancillary Documents.

                                       3

<PAGE>

         4.2 Employee Benefit Programs, Plans and Practices. The Company shall
provide Executive while employed hereunder with coverage under such employee
benefits (commensurate with his position in the Company and to the extent
permitted under any employee benefit plan) in accordance with the terms
thereof, which the Company makes available to its senior executives.

         4.3 Vacation. Executive shall be entitled to twenty (20) business days
paid vacation each calendar year, which shall be taken at such times as are
consistent with Executive's responsibilities hereunder. Any vacation days not
taken during the calendar year in which they are accrued may be carried over
into the next subsequent year.

         5. Expenses. Subject to prevailing Company policy or such guidelines
as may be established by the Board, the Company will reimburse Executive for
all reasonable expenses incurred by Executive in carrying out his duties.

         6. Termination of Employment.

         6.1 Termination Not for Cause or for Good Reason. (a) The Company or
Executive may terminate Executive's Term of Employment at any time for any
reason by written notice at least thirty (30) days in advance. If Executive's
employment is terminated (i) by the Company other than for Cause (as defined in
Section 6.2(b) hereof), Disability (as defined in Section 6.3 hereof) or death
or (ii) by Executive for Good Reason (as defined in Section 6.1(b) hereof)
prior to the end of the Initial Term or any Renewal Term, the Company shall
continue to pay Executive's Base Salary through the end of the Initial Term or
the Renewal Term (the "Continuation Period"), as the case may be, with such
payments to be made in accordance with the terms of Section 3.1. (the
"Severance Payments"). In addition, the Company shall continue to provide
Executive during the Continuation Period with life insurance, medical and
hospitalization benefits (collectively, the "Continuation Benefits") comparable
to those provided to other senior executives; provided, however,

                                       4

<PAGE>

that any such coverage shall terminate to the extent that Executive is offered
or obtains comparable life insurance, medical or hospitalization benefits
coverage from any other employer during the Continuation Period.
Notwithstanding the foregoing, if Executive breaches any provision of Section
11 hereof, the remaining balance of the Severance Payments and any Continuation
Benefits shall be forfeited. Executive shall be entitled to receive the
benefits, if any, provided under the employee benefit programs, plans and
practices referred to in Section 4.2, in accordance with their terms.

         (b) For purposes of this Agreement, "Good Reason" shall mean any of
the following (without Executive's express prior written consent):

         (i) A reduction by the Company in Executive's Base Salary (in which
     event Severance Payments shall be made based upon Executive's Base Salary
     in effect prior to any such reduction); or

         (ii) Any material diminution or material adverse change in Executive's
     titles, duties or responsibilities, unless due to a promotion or increased
     responsibility of Executive.

         (c) Termination by Executive for Good Reason shall be made by delivery
to the Company by Executive of written notice, given at least 45 days prior to
such termination, which sets forth the conduct believed to constitute Good
Reason; provided, however, that the Company shall have the opportunity to cure
the Good Reason during the first 30 days of such notice period and if the Good
Reason is cured within such 30-day period, Executive's notice of termination
shall be deemed withdrawn. If no notice is given within 90 days of the event
giving rise to Good Reason, the Good Reason shall be deemed waived.

         6.2 Voluntary Termination by Executive; Discharge for Cause. (a) In
the event that Executive's employment is terminated (i) by the Company for
Cause, as hereinafter defined or (ii) by Executive other than for Good Reason,
Disability or death, Executive shall only be entitled to receive (A) any Base
Salary accrued but unpaid prior to such termination and (B) any

                                       5

<PAGE>

benefits provided under the employee benefit programs, plans and practices
referred to in Section 4.2 hereof, in accordance with their terms. After the
termination of Executive's employment under this Section 6.2, the obligations
of the Company under this Agreement to make any further payments, or provide
any benefits specified herein, to Executive shall thereupon cease and
terminate.

         (b) As used herein, the term "Cause" shall be limited to (i) gross
neglect of or willful and continuing refusal by Executive to substantially
perform Executive's duties hereunder (other than due to death or Disability, as
such term is defined in Section 6.3 hereof), (ii) any breach of the provisions
of Section 11 of this Agreement by Executive, (iii) willfully engaging in
conduct that is demonstrably injurious to the Company or the Company's
subsidiaries or affiliates by Executive or (iv) conviction of, or plea of nolo
contendere, by Executive to (a) any felony or (b) a misdemeanor involving moral
turpitude. Termination of Executive pursuant to this Section 6.2 shall be made
by delivery to Executive of written notice, given at least 30 days prior to
such Termination, from the Board specifying the particulars of the conduct by
Executive set forth in any of clauses (i) through (iv) above. Termination shall
be effected by a majority vote of the Board at a meeting at which Executive
shall have had the opportunity (along with counsel) to be heard unless within
30 days after receiving such notice, Executive shall have cured Cause to the
reasonable satisfaction of the Board; provided, however, that no cure shall be
possible if termination for Cause is made pursuant to this Section 6.2(b)(ii)
or (iv). As long as Executive is on the Board, he shall reasonably cooperate to
cause a valid Board meeting to occur.

         6.3 Disability. In the event of the Disability (as defined below) of
Executive during the Term of Employment, the Company may terminate Executive's
Term of Employment upon written notice to Executive (or

                                       6

<PAGE>

Executive's personal representative, if applicable) effective upon the date of
receipt thereof (the "Disability Commencement Date"). The obligation of the
Company to make any further payments under this Agreement shall, except for
earned but unpaid Base Salary, cease as of the Disability Commencement Date;
provided, however, that Executive shall continue to receive payments equal to
Executive's Base Salary otherwise payable under this Agreement for a period
equal to the lesser of (i) six months after the date of the occurrence of the
incapacity causing Executive's Disability and (ii) the number of months
otherwise remaining in the Term of Employment, in either case, reduced by the
amount of any disability payments otherwise payable to Executive under any
insurance program of the Company. The term "Disability," for purposes of this
Agreement, shall mean Executive's absence from the full-time performance of
Executive's duties pursuant to a reasonable determination made in accordance
with the Company's disability plan that Executive is disabled as a result of
incapacity due to physical or mental illness that lasts, or is reasonably
expected to last, for at least six months.

         6.4 Death. In the event of Executive's death during his Term of
Employment hereunder or at any time thereafter while payments are still owing
to Executive under the terms of this Agreement, all obligations of the Company
to make any further payments, other than the obligation to pay any accrued but
unpaid Base Salary or remaining payments that were payable to Executive by
reason of his termination of employment under Section 6.1 to which Executive
was entitled at the time of his death, shall terminate upon Executive's death,
and benefits shall become payable under the Company's life and accidental death
insurance program in accordance with its terms. Benefits under all other
employee benefit programs, plans and practices shall be paid in accordance with
their terms.

         6.5 No Further Notice or Compensation. Executive understands and
agrees that he shall not be entitled to any further notice or compensation

                                       7

<PAGE>

upon Termination of Employment under this Agreement, other than amounts
specified in this Section 6 and the Ancillary Documents. Executive shall not
have any obligation to seek comparable employment following such termination or
resignation, nor shall any compensation received from any subsequent employment
reduce the Company's obligations hereunder.

         6.6 Executive's Duty to Provide Materials. Upon the termination of the
Term of Employment for any reason, Executive or his estate shall surrender to
the Company all correspondence, letters, files, contracts, mailing lists,
customer lists, advertising materials, ledgers, supplies, equipment, checks,
and all other materials and records of any kind that are the property of the
Company or any of its subsidiaries or affiliates, that may be in Executive's
possession or under his control, including all copies of any of the foregoing;
provided, however, Executive shall not be required to surrender his personal
rolodex, telephone book, appointment book and personal materials acquired by
Executive prior to the date hereof.

         7. Notices. All notices or communications hereunder shall be in
writing, addressed as follows:

         To the Company:

actual date of sending shall constitute the time at which notice was given.

         8. Separability. If any provision of this Agreement shall be declared
to be invalid or unenforceable, in whole or in part, such invalidity or
unenforceability shall not affect the remaining provisions hereof which shall
remain in full force and effect.

         9. Assignment. This contract shall be binding upon and inure to the
benefit of the heirs and representatives of Executive and the assigns and
successors of the Company, but neither this Agreement nor any rights or
obligations hereunder shall be assignable or otherwise subject to hypothecation
by Executive (except by will or, in the case of the Options, by trust for the
benefit of Executive's spouse and/or children or by operation of the laws of
intestate succession) or by the Company, except that the Company may assign
this Agreement to any successor (whether by merger, purchase or otherwise) to
all or substantially all of the stock, assets or businesses of the Company, if
such successor expressly agrees to assume the obligations of the Company
hereunder.

         10. Amendment. This Agreement may only be amended by written agreement
of the parties hereto.

         11. Nondisclosure of Confidential Information: Non-Competition. (a)
While employed by the Company, and at any time thereafter, the Executive shall
not, without the prior written consent of the Company, use, divulge, disclose
or make accessible to any other person, firm, partnership, corporation or other
entity any Confidential Information pertaining to the business of the Company
or any of its affiliates, except (i) while employed

                                       9

<PAGE>

by the Company, in the business of and for the benefit of the Company or (ii)
when required to do so by applicable law, by a court, by any governmental
agency, or by any administrative body or legislative body (including a
committee thereof); provided, however, that Executive shall give reasonable
notice under the circumstances to the Company that he has been notified that he
will be required to so disclose as soon as possible after receipt of such
notice in order to permit the Company to take whatever action it reasonably
deems necessary to prevent such disclosure and Executive shall cooperate with
the Company to the extent that it reasonably requests him to do so. For
purposes of this Section 11(a), "Confidential Information" shall mean
non-public information concerning the financial data, strategic business plans,
product development (or other proprietary product data), customer lists,
marketing plans and other non-public, proprietary and confidential information
of the Company, its subsidiaries, its affiliates or customers, that, in any
case, is not otherwise available to the public (other than by Executive's
breach of the terms hereof).

         (b) In consideration of the Company's obligations under this
Agreement, Executive agrees that during the period of his employment hereunder
and for a period of twelve (12) months thereafter, without the prior written
consent of the Board, (A) he will not, directly or indirectly, either as
principal, manager, agent, consultant, officer, stockholder, partner, investor,
lender or employee or in any other capacity, carry on, be engaged in or have
any financial interest in, any entity which is in competition with the business
of the Company or its subsidiaries and (B) he shall not, on his own behalf or
on behalf of any person, firm or company, directly or indirectly, solicit or
offer employment to any person who is or has been employed by the Company or
its subsidiaries at any time during the twelve (12) months immediately
preceding such solicitation; provided, however, that if the Executive's
employment terminates following the

                                       10

<PAGE>

expiration of the Initial Term, this subsection 11(b) shall only be effective
during the period, if any, that the Company pays the Executive the Severance
Payments.

         (c) For purposes of this Section 11, an entity shall be deemed to be
in competition with the Company if it is principally involved in the purchase,
sale or other dealing in any property or the rendering of any service
purchased, sold, dealt in or rendered by the Company as a part of the business
of the Company within the same geographic area in which the Company effects
such sales or dealings or renders such services. Notwithstanding this
subsection 11(c) or subsection 11(b), nothing herein shall (i) prohibit
Executive from serving as an officer, employee or independent consultant of any
business unit or subsidiary which would not otherwise be in competition with
the Company or its subsidiaries, but which business unit is a part of, or which
subsidiary is controlled by, or under common control with, an entity that would
be in competition with the Company or its subsidiaries, so long as Executive
does not engage in any activity which is in competition with any business of
the Company or its subsidiaries or (ii) be construed so as to preclude
Executive from investing in any publicly or privately held company, provided
Executive's beneficial ownership of any class of such company's securities does
not exceed 5% of the outstanding securities of such class.

         (d) Executive agrees that this covenant not to compete is reasonable
under the circumstances and will not interfere with his ability to earn a
living or to otherwise meet his financial obligations. Executive and the
Company agree that if in the opinion of any court of competent jurisdiction
such restraint is not reasonable in any respect, such court shall have the
right, power and authority to excise or modify such provision or provisions of
this covenant as to the court shall appear not reasonable and to enforce the
remainder of the covenant as so amended. Executive agrees that any breach of
the covenants contained in this Section 11 would

                                       11

<PAGE>

irreparably injure the Company. Accordingly, Executive agrees that, in the
event the Company determines that Executive has breached the covenants
contained in this Section 11, the Company may, in addition to pursuing any
other remedies it may have in law or in equity, cease making any payments
otherwise required by this Agreement and obtain an injunction against Executive
from any court having jurisdiction over the matter restraining any further
violation of this Agreement by Executive.

         12. Beneficiaries; References. Executive shall be entitled to select
(and change, to the extent permitted under any applicable law) a beneficiary or
beneficiaries to receive any compensation or benefit payable hereunder
following Executive's death, and may change such election, in either case by
giving the Company written notice thereof. In the event of Executive's death or
a judicial determination of his incompetence, reference in this Agreement to
Executive shall be deemed, where appropriate, to refer to his beneficiary,
estate or other legal representative. Any reference to the masculine gender in
this Agreement shall include, where appropriate, the feminine.

         13. Survivorship. The respective rights and obligations of the parties
hereunder shall survive any termination of this Agreement to the extent
necessary to the intended preservation of such rights and obligations. The
provisions of this Section 13 are in addition to the survivorship provisions of
any other section of this Agreement.

         14. Dispute Resolution; Legal Fees. Any dispute or controversy arising
under or in connection with this Agreement shall be resolved by the court with
the appropriate jurisdiction in the State of New York. The prevailing party
shall be entitled to be reimbursed for any reasonable legal fees and other fees
and expenses which may be incurred in respect of enforcing its respective
rights under this Agreement.

                                       12

<PAGE>

         15. Governing Law. This Agreement shall be construed, interpreted and
governed in accordance with the laws of the State of New York, without
reference to rules relating to conflicts of law.

         16. Effect on Prior Agreements. This Agreement and the Ancillary
Documents contain the entire understanding between the parties hereto and
supersedes in all respects any prior or other agreement or understanding, both
written and oral, between the Company, any affiliate of the Company or any
predecessor of the Company or affiliate of the Company and Executive.

may be disposed of without registration under the Securities Act in reliance on
Rule 144, such disposition can be made only in limited amounts in accordance

converted into such other class of Common Stock), the Company will file the
reports required to be filed by it under the Securities Act and the Exchange Act
to the extent required from time to time to enable the Purchaser to sell shares
of Class B Common Stock or the Option Shares, as the case may be (or Class C

converted into such other class of Common Stock) are to be disposed of in
accordance with Rule 144 under the Securities Act or otherwise, the Purchaser
shall promptly notify the Company of such intended disposition and deliver to
the Company at or prior to the time of such disposition such documentation as
the Company may reasonably request in connection with such sale and, in the case
of a disposition in accordance with Rule 144, an executed copy of Form 144
required to be filed with the SEC (if required by Rule 144). Anything to the

foregoing, the Company shall not be required to purchase for cash any shares of
Common Stock pursuant to Section 4.1 or 4.2 if (a) such purchase would be or
would result in a violation by the Company or any of its subsidiaries of (i) the
terms of any debt agreements or other documents related thereto to which the
Company or any of its subsidiaries is a party or (ii) applicable law or (b) the
Board of Directors (excluding Messrs. Lanza and LaPenta or their respective
nominees) unanimously determines that such purchase would be reasonably likely
to materially impact the Company's available cash, require unsuitable additional
debt to be incurred or otherwise have a material adverse effect on the financial
condition of the Company. If the Company is precluded from paying for all or any
portion of the shares of Common Stock in cash pursuant to the preceding
sentence, the Company shall issue a subordinated note to the Purchaser in
respect of the shares not purchased for cash or a member of the Purchaser's
Group which note shall be repaid in cash (i) from the proceeds obtained by

                                                                              11


the Company from the sale of Common Stock in an Initial Public Offering and (ii)
at such time that the Board of Directors determines that the conditions
described in the preceding sentence no longer exist; provided, that such note
shall (A) bear pay-in-kind interest at a rate per annum which, in the opinion of
an independent, mutually acceptable nationally-recognized investment banking
firm, will result in such note having a fair market value on the date of
issuance equal to the aggregate principal amount thereof, (B) be payable in full
on April 30, 2007 except as otherwise provided herein, (C) be subordinated to
the Company's obligations under any guarantee of any bank credit obligations of
its subsidiaries and (D) contain such other covenants, events of default and
other terms and conditions customary for notes of that kind. If in connection
with the exercise of rights pursuant to Section 4.1 or 4.2, the Company is
required to issue a subordinated note, at the request of the Purchaser (or the
holders of not less than a majority of the total number of shares of Class B
Common Stock, Class C Common Stock and Option Shares held by the Purchaser's
Group), the Company (by action of the Board of Directors) will in good faith
endeavor to cause L-3 Communications Corporation ("L-3") to purchase the shares
to be purchased pursuant to Section 4.1 or 4.2 in exchange for the issuance of a
subordinated note so long as such purchase is permitted by the terms of any debt
agreements or other documents related thereto to which L-3 or any of its
subsidiaries is a party; provided that in no event shall the Company (or the
Board) be required to cause L-3 to purchase such shares unless in its judgment
such purchase on the terms set forth herein would not have a material adverse
impact on L-3's ability to raise debt financing on commercially reasonable
terms. Any subordinated note issued by L-3 pursuant to the foregoing shall
contain such covenants, events of default and other terms and conditions
customary for notes of that kind, including terms described in (A)-(C) above,
except that (i) interest on such note shall be payable in cash and (ii) such
note shall be payable in full on August 15, 2007 except as otherwise provided
herein and shall be subordinated to L-3's obligations under any bank credit
obligations or senior subordinated debt. In the event that the Company is
precluded from paying for all or any portion of the shares of Common Stock in
cash because such purchase would be or would result in a violation by the
Company or any of its subsidiaries of the terms of any debt agreements or other
documents related thereto to which the Company or any of the subsidiaries is a
party, the Company shall use its reasonable best efforts to obtain, or cause any
such subsidiary to obtain, a waiver under such debt agreements or other
agreements of such term or terms to allow the Company to pay for all or any
portion of the shares of Common Stock in cash.

            4.4 Termination of Put/Call Rights. The rights and obligations set
forth in this Section 4 shall lapse upon a Public Offering.

5. Shares Subject to Forfeiture

            5.1 Forfeiture Events. If prior to the third anniversary of the
Closing Date, there is a Termination of Employment of the Purchaser for Cause or
the Purchaser resigns without Good Reason or retires, then all of the Shares
Subject to Forfeiture shall be forfeited (whether or not then held by Purchaser)
(each such event, a "Forfeiture Event").

            5.2 Lapse of Forfeiture Restrictions. (a) The Shares Subject to
Forfeiture shall no longer be subject to forfeiture upon the earliest to occur
of the following events (each such event, a "Restriction Lapse"): (i) the date
of death of the Purchaser; (ii) the date of Disability of the Purchaser; (iii)
the date that the Purchaser resigns for Good Reason or is terminated without
Cause; (iv) the date that the Company consummates a Public Offering at a FMV per
Share of at least $6.47; (v) the date of the closing of a transaction resulting
in a Change of Control or any other transaction involving the acquisition by a
Person other than an Affiliate of Lehman of shares of Class A Common Stock
representing 10% or more of the Class A Common Stock held by Lehman and LBHI
(and their Permitted Transferees, as such term is defined in the Stockholders
Agreement) on the Closing Date), in each case yielding a price per share in such
transaction of at least $6.47; (vi) the first date following a Public Offering
that the FMV per Share based on the average of the closing sales prices for the
20 trading days prior to such date equals or exceeds $6.47; or (vii) the date of
consummation of a transaction referred to in Section 5.1(ii)(c). Shares Subject
to Forfeiture shall be deemed no longer subject to forfeiture immediately prior
to the occurrence of the Restriction Lapse referred to in clause (iv) or (v) of
this Section 5.2.

            (b) Notwithstanding the foregoing, the Shares Subject to Forfeiture
shall no longer be subject to forfeiture on the date that is nine years after
the Closing Date (but only to the extent that the Shares Subject to Forfeiture
have not previously been forfeited). Any such lapse of the restrictions on the
Shares Subject to Forfeiture pursuant to this Section 5.2(b) shall be a
"Restriction Lapse".

            5.3 Conversion. (a) Upon the later to occur of (i) the consummation
of the Initial Public Offering and (ii) such time as there shall have occured a
Forfeiture Event or Restriction Lapse as to both of the Initial Holders of Class
B Common Stock, all of the Class B Common Stock held by the Purchaser's Group
shall be converted to shares of Class A Common Stock in accordance with the
terms of the Certificate of Incorporation of the Company.

            (b) Upon the occurrence of a Forfeiture Event or Restriction Lapse
with respect to the Purchaser that occurs prior to both the consummation of the
Initial Public Offering and the occurrence of a Forfeiture Event or Restriction
Lapse with
<PAGE>

                                                                              13


respect to the other Initial Holder of Class B Common Stock, all of the Class B
Common Stock held by the Purchaser's Group shall be converted to shares of Class
C Common Stock in accordance with the terms of the Certificate of Incorporation
of the Company.

6. Miscellaneous.

            6.1 Recapitalization, Exchanges, Etc., Affecting Common Stock. The
provisions of this Agreement shall apply, to the full extent set forth herein,
to any and all shares of capital stock of the Company or any successor or assign
of the Company (whether by merger, consolidation, sale of assets or otherwise)
which may be issued in respect or upon conversion of, in exchange for, or in
substitution of the Class B Common Stock purchased pursuant hereto (or the Class
A Common Stock or Class C Common Stock to which such Class B Common Stock has
been converted, as the case may be) and the Option Shares, by reason of any
stock dividend, stock split, reverse stock split, combination, recapitalization,
reclassification, merger, consolidation or otherwise. In the event that any of
the foregoing events shall occur, then and in each such case, the number of
shares and price per share of Class B Common Stock purchased pursuant to this
Agreement (or the Class A Common Stock or Class C Common Stock to which such
Class B Common Stock has been converted, as the case may be) and any terms of
this Agreement referring to such number of shares or price per share and the
number of Option Shares received by the Purchaser upon the exercise of any
Options shall, in each such case, be equitably and appropriately adjusted.

            6.2 Binding Effect. The provisions of this Agreement shall be
binding upon and accrue to the benefit of the parties hereto and their
respective heirs, legal representatives, successors and assigns. In the case of
a transferee permitted under Section 3.2 hereof, such transferee shall be deemed
to be the Purchaser hereunder; provided, however, that no transferee (including,
without limitation, transferees referred to in Section 3.2 hereof) shall derive
any rights under this Agreement unless and until such transferee has delivered
to the Company a valid undertaking and becomes bound by the terms of this
Agreement.

            6.3 Amendment. This Agreement may be amended only by a written
instrument signed by the Company and holders of a majority of the Class B Common
Stock purchased pursuant hereto and the Option Shares, and any such amendment
shall be effective against the Company and all holders of the Class B Common
Stock and Option Shares.

            6.4 Applicable Law. The laws of the State of New York shall govern
the interpretation, validity and performance of the terms of this Agreement.

                              EMPLOYMENT AGREEMENT


         AGREEMENT, made April 30, 1997 by and between L-3 Communications
Holdings, Inc., a Delaware corporation (the "Company") and Robert V. LaPenta
(the "Executive").


                                    RECITALS


         In order to induce Executive to serve as the President and Chief
Financial Officer of the Company, the Company desires to provide Executive with
compensation and other benefits on the terms and conditions set forth in this
Agreement.

         Executive is willing to accept such employment and perform services
for the Company, on the terms and conditions hereinafter set forth.

         It is therefore hereby agreed by and between the parties as follows:

         1. Employment.

         1.1 Subject to the terms and conditions of this Agreement, the Company
agrees to employ Executive during the Term hereof as its President and Chief
Financial Officer. In his capacity as the President and Chief Financial
Executive Officer of the Company, Executive shall report to the Chief Executive
Officer (the "CEO") and shall have the customary powers, responsibilities and
authorities of presidents and chief financial officers of corporations of the
size, type and nature of the Company, as it exists from time to time, and as
are assigned by the CEO.

         1.2 Subject to the terms and conditions of this Agreement, Executive
hereby accepts employment as the President and Chief Financial Officer of the
Company commencing as of the date hereof (the "Commencement Date") and agrees
to devote his full business time and efforts to the

                                       1

<PAGE>

performance of services, duties and responsibilities in connection therewith,
subject at all times to review and control of the CEO. In addition, during the
Initial Term and any Renewal Term, (i) the Company agrees to nominate Executive
for election to the Board of Directors of the Company (the "Board") and use its
best efforts to cause his election to the Board and Executive agrees to serve
on the Board of the Company and (ii) during the Term of Employment, Executive
also agrees to serve, if elected, as an officer and/or director of any
Subsidiary of the Company, without the payment of any additional compensation
therefor. Upon the termination of Executive's employment for any reason,
Executive shall resign as a member of the Board of the Company or any
Subsidiary of the Company.

         1.3 Nothing in this Agreement shall preclude Executive from engaging
in charitable work and community affairs, from managing any investment made by
him with respect to which Executive is not substantially involved with the
management or operation of the entity in which Executive has invested (provided
that no such investment in publicly traded equity securities or other property
may exceed 5% of the equity of any entity, without the prior approval of the
Board) or from serving, subject to the prior approval of the Board, as a member
of boards of directors or as a trustee of any other corporation, association or
entity, to the extent that any of the above activities do not materially
interfere with the performance of his duties hereunder. For purposes of the
preceding sentence, any approval by the Board required therein shall not be
unreasonably withheld.

         2. Term of Employment. Executive's term of employment under this
Agreement (the "Term of Employment") shall commence on the Commencement Date
and, subject to the terms hereof, shall terminate on the earlier of (i) the
fifth anniversary of the Commencement Date "Initial Term") or (ii) termination
of Executive's employment pursuant to this Agreement. Notwithstanding the
foregoing, subsequent to the Initial Term, Executive's

                                       2

<PAGE>

Term of Employment under this Agreement shall automatically renew annually for
one year renewal terms (the "Renewal Term") unless either party shall deliver
to the other written notice, at least 90 days prior to the expiration of the
Initial Term or any Renewal Term, that the Term of Employment shall not be
extended. In such event, the Term of Employment will end at its then scheduled
expiration date and shall not be further extended except by written agreement
of the Company and Executive.

         3. Compensation.

         3.1 Salary. During the Initial Term of Executive's employment under
the terms of this Agreement, the Company shall pay Executive a base salary
("Base Salary") at an initial rate of $500,000 per annum. Base Salary shall be
payable in accordance with the ordinary payroll practices of the Company.
During the Term of Employment, the Board shall, in good faith, review, at least
annually, the Executive's Base Salary in accordance with the Company's
customary procedures and practices regarding the salaries of senior executives
and may, if determined by the Board to be appropriate, increase Executive's
Base Salary following such review. Increases in the rate of salary, once
granted, shall not be subject to revocation or decrease thereafter, and "Base
Salary" for all purposes herein shall be deemed to be a reference to such
higher amount.

         4. Employee Benefits.

         4.1 Equity and Stock Options. Simultaneously with the execution of
this Agreement, the Company and Executive are entering into the Subscription
Agreement, the Option Agreement and the Stockholders' Agreement in the forms
attached hereto as Exhibits A, B and C, respectively (the "Ancillary
Documents"). Executive shall not be eligible to receive any stock option or
other equity incentive other than as set forth in the Ancillary Documents.

                                       3

<PAGE>

         4.2 Employee Benefit Programs, Plans and Practices. The Company shall
provide Executive while employed hereunder with coverage under such employee
benefits (commensurate with his position in the Company and to the extent
permitted under any employee benefit plan) in accordance with the terms
thereof, which the Company makes available to its senior executives.

         4.3 Vacation. Executive shall be entitled to twenty (20) business days
paid vacation each calendar year, which shall be taken at such times as are
consistent with Executive's responsibilities hereunder. Any vacation days not
taken during the calendar year in which they are accrued may be carried over
into the next subsequent year.

         5. Expenses. Subject to prevailing Company policy or such guidelines
as may be established by the Board, the Company will reimburse Executive for
all reasonable expenses incurred by Executive in carrying out his duties.

         6. Termination of Employment.

         6.1 Termination Not for Cause or for Good Reason. (a) The Company or
Executive may terminate Executive's Term of Employment at any time for any
reason by written notice at least thirty (30) days in advance. If Executive's
employment is terminated (i) by the Company other than for Cause (as defined in
Section 6.2(b) hereof), Disability (as defined in Section 6.3 hereof) or death
or (ii) by Executive for Good Reason (as defined in Section 6.1(b) hereof)
prior to the end of the Initial Term or any Renewal Term, the Company shall
continue to pay Executive's Base Salary through the end of the Initial Term or
the Renewal Term (the "Continuation Period"), as the case may be, with such
payments to be made in accordance with the terms of Section 3.1. (the
"Severance Payments"). In addition, the Company shall continue to provide
Executive during the Continuation Period with life insurance, medical and
hospitalization benefits (collectively, the "Continuation Benefits") comparable
to those provided to other senior executives; provided, however,

                                       4

<PAGE>

that any such coverage shall terminate to the extent that Executive is offered
or obtains comparable life insurance, medical or hospitalization benefits
coverage from any other employer during the Continuation Period.
Notwithstanding the foregoing, if Executive breaches any provision of Section
11 hereof, the remaining balance of the Severance Payments and any Continuation
Benefits shall be forfeited. Executive shall be entitled to receive the
benefits, if any, provided under the employee benefit programs, plans and
practices referred to in Section 4.2, in accordance with their terms.

         (b) For purposes of this Agreement, "Good Reason" shall mean any of
the following (without Executive's express prior written consent):

          (i) A reduction by the Company in Executive's Base Salary (in which
     event Severance Payments shall be made based upon Executive's Base Salary
     in effect prior to any such reduction); or

         (ii) Any material diminution or material adverse change in Executive's
     titles, duties or responsibilities, unless due to a promotion or increased
     responsibility of Executive.

         (c) Termination by Executive for Good Reason shall be made by delivery
to the Company by Executive of written notice, given at least 45 days prior to
such termination, which sets forth the conduct believed to constitute Good
Reason; provided, however, that the Company shall have the opportunity to cure
the Good Reason during the first 30 days of such notice period and if the Good
Reason is cured within such 30-day period, Executive's notice of termination
shall be deemed withdrawn. If no notice is given within 90 days of the event
giving rise to Good Reason, the Good Reason shall be deemed waived.

         6.2 Voluntary Termination by Executive; Discharge for Cause. (a) In
the event that Executive's employment is terminated (i) by the Company for
Cause, as hereinafter defined or (ii) by Executive other than for Good Reason,
Disability or death, Executive shall only be entitled to receive (A) any Base
Salary accrued but unpaid prior to such termination and (B) any

                                       5

<PAGE>

benefits provided under the employee benefit programs, plans and practices
referred to in Section 4.2 hereof, in accordance with their terms. After the
termination of Executive's employment under this Section 6.2, the obligations
of the Company under this Agreement to make any further payments, or provide
any benefits specified herein, to Executive shall thereupon cease and
terminate.

         (b) As used herein, the term "Cause" shall be limited to (i) gross
neglect of or willful and continuing refusal by Executive to substantially
perform Executive's duties hereunder (other than due to death or Disability, as
such term is defined in Section 6.3 hereof), (ii) any breach of the provisions
of Section 11 of this Agreement by Executive, (iii) willfully engaging in
conduct that is demonstrably injurious to the Company or the Company's
subsidiaries or affiliates by Executive or (iv) conviction of, or plea of nolo
contendere, by Executive to (a) any felony or (b) a misdemeanor involving moral
turpitude. Termination of Executive pursuant to this Section 6.2 shall be made
by delivery to Executive of written notice, given at least 30 days prior to
such Termination, from the Board specifying the particulars of the conduct by
Executive set forth in any of clauses (i) through (iv) above. Termination shall
be effected by a majority vote of the Board at a meeting at which Executive
shall have had the opportunity (along with counsel) to be heard unless within
30 days after receiving such notice, Executive shall have cured Cause to the
reasonable satisfaction of the Board; provided, however, that no cure shall be
possible if termination for Cause is made pursuant to this Section 6.2(b)(ii)
or (iv). As long as Executive is on the Board, he shall reasonably cooperate to
cause a valid Board meeting to occur.

         6.3 Disability. In the event of the Disability (as defined below) of
Executive during the Term of Employment, the Company may terminate Executive's
Term of Employment upon written notice to Executive (or

                                       6

<PAGE>

Executive's personal representative, if applicable) effective upon the date of
receipt thereof (the "Disability Commencement Date"). The obligation of the
Company to make any further payments under this Agreement shall, except for
earned but unpaid Base Salary, cease as of the Disability Commencement Date;
provided, however, that Executive shall continue to receive payments equal to
Executive's Base Salary otherwise payable under this Agreement for a period
equal to the lesser of (i) six months after the date of the occurrence of the
incapacity causing Executive's Disability and (ii) the number of months
otherwise remaining in the Term of Employment, in either case, reduced by the
amount of any disability payments otherwise payable to Executive under any
insurance program of the Company. The term "Disability," for purposes of this
Agreement, shall mean Executive's absence from the full-time performance of
Executive's duties pursuant to a reasonable determination made in accordance
with the Company's disability plan that Executive is disabled as a result of
incapacity due to physical or mental illness that lasts, or is reasonably
expected to last, for at least six months.

         6.4 Death. In the event of Executive's death during his Term of

unenforceability shall not affect the remaining provisions hereof which shall
remain in full force and effect.

         9. Assignment. This contract shall be binding upon and inure to the
benefit of the heirs and representatives of Executive and the assigns and
successors of the Company, but neither this Agreement nor any rights or
obligations hereunder shall be assignable or otherwise subject to hypothecation
by Executive (except by will or, in the case of the Options, by trust for the
benefit of Executive's spouse and/or children or by operation of the laws of
intestate succession) or by the Company, except that the Company may assign
this Agreement to any successor (whether by merger, purchase or otherwise) to
all or substantially all of the stock, assets or businesses of the Company, if
such successor expressly agrees to assume the obligations of the Company
hereunder.

         10. Amendment. This Agreement may only be amended by written agreement
of the parties hereto.

         11. Nondisclosure of Confidential Information; Non-Competition. (a)
While employed by the Company, and at any time thereafter, the Executive shall
not, without the prior written consent of the Company, use, divulge, disclose
or make accessible to any other person, firm, partnership, corporation or other
entity any Confidential Information pertaining to the business of the Company
or any of its affiliates, except (i) while employed

                                       9

<PAGE>

by the Company, in the business of and for the benefit of the Company or (ii)
when required to do so by applicable law, by a court, by any governmental
agency, or by any administrative body or legislative body (including a
committee thereof); provided, however, that Executive shall give reasonable
notice under the circumstances to the Company that he has been notified that he
will be required to so disclose as soon as possible after receipt of such
notice in order to permit the Company to take whatever action it reasonably
deems necessary to prevent such disclosure and Executive shall cooperate with
the Company to the extent that it reasonably requests him to do so. For
purposes of this Section 11(a), "Confidential Information" shall mean
non-public information concerning the financial data, strategic business plans,
product development (or other proprietary product data), customer lists,
marketing plans and other non-public, proprietary and confidential information
of the Company, its subsidiaries, its affiliates or customers, that, in any
case, is not otherwise available to the public (other than by Executive's
breach of the terms hereof).

         (b) In consideration of the Company's obligations under this
Agreement, Executive agrees that during the period of his employment hereunder
and for a period of twelve (12) months thereafter, without the prior written
consent of the Board, (A) he will not, directly or indirectly, either as
principal, manager, agent, consultant, officer, stockholder, partner, investor,
lender or employee or in any other capacity, carry on, be engaged in or have
any financial interest in, any entity which is in competition with the business
of the Company or its subsidiaries and (B) he shall not, on his own behalf or
on behalf of any person, firm or company, directly or indirectly, solicit or
offer employment to any person who is or has been employed by the Company or
its subsidiaries at any time during the twelve (12) months immediately
preceding such solicitation; provided, however, that if the Executive's
employment terminates following the

                                       10

<PAGE>

expiration of the Initial Term, this subsection 11(b) shall only be effective
during the period, if any, that the Company pays the Executive the Severance
Payments.

         (c) For purposes of this Section 11, an entity shall be deemed to be
in competition with the Company if it is principally involved in the purchase,
sale or other dealing in any property or the rendering of any service
purchased, sold, dealt in or rendered by the Company as a part of the business
of the Company within the same geographic area in which the Company effects
such sales or dealings or renders such services. Notwithstanding this
subsection 11(c) or subsection 11(b), nothing herein shall (i) prohibit
Executive from serving as an officer, employee or independent consultant of any
business unit or subsidiary which would not otherwise be in competition with
the Company or its subsidiaries, but which business unit is a part of, or which
subsidiary is controlled by, or under common control with, an entity that would
be in competition with the Company or its subsidiaries, so long as Executive
does not engage in any activity which is in competition with any business of
the Company or its subsidiaries or (ii) be construed so as to preclude
Executive from investing in any publicly or privately held company, provided
Executive's beneficial ownership of any class of such company's securities does
not exceed 5% of the outstanding securities of such class.

         (d) Executive agrees that this covenant not to compete is reasonable
under the circumstances and will not interfere with his ability to earn a
living or to otherwise meet his financial obligations. Executive and the
Company agree that if in the opinion of any court of competent jurisdiction
such restraint is not reasonable in any respect, such court shall have the
right, power and authority to excise or modify such provision or provisions of
this covenant as to the court shall appear not reasonable and to enforce the
remainder of the covenant as so amended. Executive agrees that any breach of
the covenants contained in this Section 11 would

                                       11

<PAGE>

irreparably injure the Company. Accordingly, Executive agrees that, in the
event the Company determines that Executive has breached the covenants
contained in this Section 11, the Company may, in addition to pursuing any
other remedies it may have in law or in equity, cease making any payments
otherwise required by this Agreement and obtain an injunction against Executive
from any court having jurisdiction over the matter restraining any further
violation of this Agreement by Executive.

         12. Beneficiaries; References. Executive shall be entitled to select
(and change, to the extent permitted under any applicable law) a beneficiary or
beneficiaries to receive any compensation or benefit payable hereunder
following Executive's death, and may change such election, in either case by
giving the Company written notice thereof. In the event of Executive's death or
a judicial determination of his incompetence, reference in this Agreement to
Executive shall be deemed, where appropriate, to refer to his beneficiary,
estate or other legal representative. Any reference to the masculine gender in
this Agreement shall include, where appropriate, the feminine.

         13. Survivorship. The respective rights and obligations of the parties
hereunder shall survive any termination of this Agreement to the extent
necessary to the intended preservation of such rights and obligations. The
provisions of this Section 13 are in addition to the survivorship provisions of
any other section of this Agreement.

         14. Dispute Resolution; Legal Fees. Any dispute or controversy arising
under or in connection with this Agreement shall be resolved by the court with
the appropriate jurisdiction in the State of New York. The prevailing party
shall be entitled to be reimbursed for any reasonable legal fees and other fees
and expenses which may be incurred in respect of enforcing its respective
rights under this Agreement.

                                       12

<PAGE>

         15. Governing Law. This Agreement shall be construed, interpreted and
governed in accordance with the laws of the State of New York, without
reference to rules relating to conflicts of law.

         16. Effect on Prior Agreements. This Agreement and the Ancillary
Documents contain the entire understanding between the parties hereto and
supersedes in all respects any prior or other agreement or understanding, both
written and oral, between the Company, any affiliate of the Company or any
predecessor of the Company or affiliate of the Company and Executive.

         17. Withholding. The Company shall be entitled to withhold from
payment any amount of withholding required by law.

         18. Survival. Notwithstanding the expiration of the term of this
Agreement, the provisions of Section 11 hereunder shall remain in effect as
long as is reasonably necessary to give effect thereto in accordance with the
terms hereof.

         19. Counterparts. This Agreement may be executed in two or more
counterparts, each of which will be deemed an original.

of the Class B Common Stock and the Option Shares have not been registered under
the Securities Act; (b) the Class B Common Stock and the Option Shares must be
held indefinitely and the Purchaser must continue to bear the economic risk of
the investment in the Class B Common Stock unless the offer and sale of such
Class B Common Stock or Option Shares is subsequently registered under the
Securities Act and all applicable state securities laws or an exemption from
such registration is available; (c) there is no established market for the Class
B Common Stock or Option Shares and it is not anticipated that there will be any
public market for the Class B Common Stock or Option Shares in the foreseeable
future; (d) Rule 144 promulgated under the Securities Act is not presently
available with respect to the sale of any securities of the Company, and, except
as set forth in Section 3.6, the Company has made no covenant to make such Rule
available; (e) when and if shares of the Class B Common Stock or Option Shares
may be disposed of without registration under the Securities Act in reliance on
Rule 144, such disposition can be made only in limited amounts in accordance
with the terms and conditions of such Rule; (f) if the Rule 144 exemption is not
available, public offer or sale without registration will require compliance
with Regulation A or the availability of an exemption under the Securities Act;
(g) a restrictive legend in the form heretofore set forth shall be placed on the
certificates representing the Class B Common Stock or Option Shares; and (h) a
notation shall be made in the appropriate records of the Company indicating that
the Class B Common Stock and the Option Shares are subject to restrictions on
transfer and, if the Company should at some time in the future engage the
services of a securities transfer agent, appropriate stop-transfer instructions
will be issued to such transfer agent with respect to the Class B Common Stock
and the Option Shares.

            3.6 Rule 144. If the Company shall have filed a registration
statement with respect to the Class B Common Stock or the Option Shares pursuant
to the requirements of Section 12 of the Exchange Act or a registration
statement with respect to the Class B Common Stock or the Option Shares pursuant
to the requirements of the Securities Act (or a registration statement shall
have been filed, in either case, with respect to the Class A Common Stock or
Class C Common Stock if any shares of the Class B Common Stock have been
converted into such other class of Common Stock), the Company will file the
reports required to be filed by it under the Securities Act and the Exchange Act
to the extent required from time to time to enable the Purchaser to sell shares
of Class B Common Stock or the Option Shares, as the case may be (or Class C
Common Stock or Class A Common Stock if any shares of the Class B Common Stock
have been converted into such other class of Common Stock), without registration
under the Securities Act within the limitation of the exemptions provided

<PAGE>
                                                                               8


by (a) Rule 144 under the Securities Act, as such Rule may be amended from time
to time, or (b) any similar rule or regulation hereafter adopted by the SEC. If
any shares of Class B Common Stock or Option Shares (or Class A Common Stock or
Class C Common Stock if any shares of the Class B Common Stock have been
converted into such other class of Common Stock) are to be disposed of in
accordance with Rule 144 under the Securities Act or otherwise, the Purchaser
shall promptly notify the Company of such intended disposition and deliver to
the Company at or prior to the time of such disposition such documentation as
the Company may reasonably request in connection with such sale and, in the case
of a disposition in accordance with Rule 144, an executed copy of Form 144
required to be filed with the SEC (if required by Rule 144). Anything to the
contrary contained in this Section 3.6 notwithstanding, the Company may
deregister any of its securities under the Exchange Act if it is then permitted
to do so pursuant to the Exchange Act.

            3.7 Additional Investment Representations. The Purchaser further
represents and warrants that (a) in making his decision to purchase the Common
Stock hereby subscribed for or exercise his options to purchase the Option
Shares, the Purchaser has relied upon independent investigations made by him
and, to the extent believed by the Purchaser to be appropriate, his
representatives, including his own professional, financial, tax and other
advisors; and (b) the Purchaser has been given the opportunity to examine all
documents and to ask questions of, and to receive answers from, the Company and
its representatives concerning the terms and conditions of the purchase of the
Class B Common Stock and to obtain any additional information which the
Purchaser deems necessary.

            3.8 Other Agreements. On the date hereof, the Stockholders
Agreement, in the form previously delivered to the Purchaser, will be entered
into by the Company, the Purchaser and other parties thereto.

            (c) In the event of any Termination of Employment for Cause or

may only be exercised by holders of not less than a majority of the total shares
of Class B Common Stock or Class C Common Stock, as the case may be, and Option
Shares held by the Purchaser's Group and the decision to exercise such rights
will be binding upon each member of the Purchaser's Group. If the Purchaser's
Group desires to exercise its rights pursuant to this Section 4.2 following any
Termination of Employment, the Purchaser's Group shall give written notice of
such intent to the Company no later than the earlier of (i) 90 days after the
Company gives notice that it will not exercise its rights under Section 4.1 and
(ii) 15 days after the expiration of the Company's rights under Section 4.1. The
closing of such purchase shall take place at the principal office of the Company
within 30 days after the giving of such written notice to the Company. The
Purchaser's Group's rights to put under this Section 4.2 may not be exercised in
part.

            4.3 Payment of Purchase Price by the Company. Notwithstanding the
foregoing, the Company shall not be required to purchase for cash any shares of
Common Stock pursuant to Section 4.1 or 4.2 if (a) such purchase would be or
would result in a violation by the Company or any of its subsidiaries of (i) the
terms of any debt agreements or other documents related thereto to which the
Company or any of its subsidiaries is a party or (ii) applicable law or (b) the
Board of Directors (excluding Messrs. Lanza and LaPenta or their respective
nominees) unanimously determines that such purchase would be reasonably likely
to materially impact the Company's available cash, require unsuitable additional
debt to be incurred or otherwise have a material adverse effect on the financial
condition of the Company. If the Company is precluded from paying for all or any
portion of the shares of Common Stock in cash pursuant to the preceding
sentence, the Company shall issue a subordinated note to the Purchaser in
respect of the shares not purchased for cash or a member of the Purchaser's
Group which note shall be repaid in cash (i) from the proceeds obtained by

<PAGE>
                                                                              11


the Company from the sale of Common Stock in an Initial Public Offering and (ii)
at such time that the Board of Directors determines that the conditions
described in the preceding sentence no longer exist; provided, that such note
shall (A) bear pay-in-kind interest at a rate per annum which, in the opinion of
an independent, mutually acceptable nationally-recognized investment banking
firm, will result in such note having a fair market value on the date of
issuance equal to the aggregate principal amount thereof, (B) be payable in full
on April 30, 2007 except as otherwise provided herein, (C) be subordinated to
the Company's obligations under any guarantee of any bank credit obligations of
its subsidiaries and (D) contain such other covenants, events of default and
other terms and conditions customary for notes of that kind. If in connection
with the exercise of rights pursuant to Section 4.1 or 4.2, the Company is
required to issue a subordinated note, at the request of the Purchaser (or the
holders of not less than a majority of the total number of shares of Class B
Common Stock, Class C Common Stock and Option Shares held by the Purchaser's
Group), the Company (by action of the Board of Directors) will in good faith
endeavor to cause L-3 Communications Corporation ("L-3") to purchase the shares
to be purchased pursuant to Section 4.1 or 4.2 in exchange for the issuance of a
subordinated note so long as such purchase is permitted by the terms of any debt
agreements or other documents related thereto to which L-3 or any of its
subsidiaries is a party; provided that in no event shall the Company (or the
Board) be required to cause L-3 to purchase such shares unless in its judgment
such purchase on the terms set forth herein would not have a material adverse
impact on L-3's ability to raise debt financing on commercially reasonable
terms. Any subordinated note issued by L-3 pursuant to the foregoing shall
contain such covenants, events of default and other terms and conditions
customary for notes of that kind, including terms described in (A) - (C) above,
except that (i) interest on such note shall be payable in cash and (ii) such
note shall be payable in full on August 15, 2007 except as otherwise provided
herein and shall be subordinated to L-3's obligations under any bank credit
obligations or senior subordinated debt. In the event that the Company is
precluded from paying for all or any portion of the shares of Common Stock in
cash because such purchase would be or would result in a violation by the
Company or any of its subsidiaries of the terms of any debt agreements or other
documents related thereto to which the Company or any of the subsidiaries is a
party, the Company shall use its reasonable best efforts to obtain, or cause any
such subsidiary to obtain, a waiver under such debt agreements or other
agreements of such term or terms to allow the Company to pay for all or any
portion of the shares of Common Stock in cash.

             4.4 Termination of Put/Call Rights. The rights and obligations set
forth in this Section 4 shall lapse upon a Public Offering.

                                                                              12


5. Shares Subject to Forfeiture

            5.1 Forfeiture Events. If prior to the third anniversary of the
Closing Date, there is a Termination of Employment of the Purchaser for Cause or
the Purchaser resigns without Good Reason or retires, then all of the Shares
Subject to Forfeiture shall be forfeited (whether or not then held by Purchaser)
(each such event, a "Forfeiture Event").

            5.2 Lapse of Forfeiture Restrictions. (a) The Shares Subject to
Forfeiture shall no longer be subject to forfeiture upon the earliest to occur
of the following events (each such event, a "Restriction Lapse"): (i) the date
of death of the Purchaser; (ii) the date of Disability of the Purchaser; (iii)
the date that the Purchaser resigns for Good Reason or is terminated without
Cause; (iv) the date that the Company consummates a Public Offering at a FMV per
Share of at least $6.47; (v) the date of the closing of a transaction resulting
in a Change of Control or any other transaction involving the acquisition by a
Person other than an Affiliate of Lehman of shares of Class A Common Stock
representing 10% or more of the Class A Common Stock held by Lehman and LBHI
(and their Permitted Transferees, as such term is defined in the Stockholders
Agreement) on the Closing Date), in each case yielding a price per share in such
transaction of at least $6.47; (vi) the first date following a Public Offering
that the FMV per Share based on the average of the closing sales prices for the
20 trading days prior to such date equals or exceeds $6.47; or (vii) the date of
consummation of a transaction referred to in Section 5.1(ii) (c). Shares Subject
to Forfeiture shall be deemed no longer subject to forfeiture immediately prior
to the occurrence of the Restriction Lapse referred to in clause (iv) or (v) of
this Section 5.2.

            (b) Notwithstanding the foregoing, the Shares Subject to Forfeiture
shall no longer be subject to forfeiture on the date that is nine years after
the Closing Date (but only to the extent that the Shares Subject to Forfeiture
have not previously been forfeited). Any such lapse of the restrictions on the
Shares Subject to Forfeiture pursuant to this Section 5.2(b) shall be a
"Restriction Lapse".

            5.3 Conversion. (a) Upon the later to occur of (i) the consummation
of the Initial Public Offering and (ii) such time as there shall have occured a
Forfeiture Event or Restriction Lapse as to both of the Initial Holders of Class
B Common Stock, all of the Class B Common Stock held by the Purchaser's Group
shall be converted to shares of Class A Common Stock in accordance with the
terms of the Certificate of Incorporation of the Company.

            (b) Upon the occurrence of a Forfeiture Event or Restriction Lapse
with respect to the Purchaser that occurs prior to both the consummation of the
Initial Public Offering and the occurrence of a Forfeiture Event or Restriction
Lapse with

<PAGE>
                                                                              13


respect to the other Initial Holder of Class B Common Stock, all of the Class B
Common Stock held by the Purchaser's Group shall be converted to shares of Class
C Common Stock in accordance with the terms of the Certificate of Incorporation
of the Company.

6. Miscellaneous.

            6.1 Recapitalization, Exchanges, Etc., Affecting Common Stock. The
provisions of this Agreement shall apply, to the full extent set forth herein,
to any and all shares of capital stock of the Company or any successor or assign
of the Company (whether by merger, consolidation, sale of assets or otherwise)
which may be issued in respect or upon conversion of, in exchange for, or in
substitution of the Class B Common Stock purchased pursuant hereto (or the Class
A Common Stock or Class C Common Stock to which such Class B Common Stock has
been converted, as the case may be) and the Option Shares, by reason of any
stock dividend, stock split, reverse stock split, combination, recapitalization,
reclassification, merger, consolidation or otherwise. In the event that any of
the foregoing events shall occur, then and in each such case, the number of

Agreement (or the Class A Common Stock or Class C Common Stock to which such
Class B Common Stock has been converted, as the case may be) and any terms of
this Agreement referring to such number of shares or price per share and the
number of Option Shares received by the Purchaser upon the exercise of any
Options shall, in each such case, be equitably and appropriately adjusted.

            6.2 Binding Effect. The provisions of this Agreement shall be
binding upon and accrue to the benefit of the parties hereto and their
respective heirs, legal representatives, successors and assigns. In the case of
a transferee permitted under Section 3.2 hereof, such transferee shall be deemed
to be the Purchaser hereunder; provided, however, that no transferee (including,
without limitation, transferees referred to in Section 3.2 hereof) shall derive
any rights under this Agreement unless and until such transferee has delivered
to the Company a valid undertaking and becomes bound by the terms of this
Agreement.

            6.3 Amendment. This Agreement may be amended only by a written
instrument signed by the Company and holders of a majority of the Class B Common
Stock purchased pursuant hereto and the Option Shares, and any such amendment
shall be effective against the Company and all holders of the Class B Common
Stock and Option Shares.

            6.4 Applicable Law. The laws of the State of New York shall govern
the interpretation, validity and performance of the terms of this Agreement.

under the Lease and any rights to extend or renew the Lease) and the Assignee
accepts from the Assignor all of the Assignor's right, title and interest in,

          2. Assumption of Lease Obligation. Assignee assumes and agrees to
perform and fulfill all terms, covenants, conditions and obligations required
to be performed and fulfilled by the Assignor under the Lease, including,
without limitation, the obligation to make all payments due or payable on
behalf of the Assignor under the Lease as they become due and payable.

          3. Representations of Assignor and Landlord. The Assignor and the
Landlord represent to the Assignee as follows:

          (a) The Lease attached hereto as Exhibit A is a true, correct and
complete copy of the Lease (including all modifications, amendments and
supplements thereof) and the same are the only agreements between Landlord and
the Assignor with respect to the subject matter thereof.

          (b) The Lease is in full force and effect and, except for the
modifications, amendments and supplements included in Exhibit A, the Lease has
not been modified, amended or supplemented.

          (c) Except as set forth on Exhibit B, no default by the Assignor or
the Landlord has occurred and is continuing under the Lease, and no event has
occurred and is continuing which with the giving of notice or the lapse of time
or both would constitute a default thereunder.

          (d) No minimum or base rent or other rental has been paid in advance
(except for the current month).

          (e) The monthly amount of base rent due under the Lease as of May 1,

          The Landlord hereby consents to the Assignor's assignment of the
Lease to the Assignee and the Assignee's assumption of the Lease. Landlord's
consent to the Assignor's assignment of the Lease to the Assignee shall not be
deemed to release the Assignor from any of its obligations under the Lease or
to alter any provision of the Lease and/or the primary liability of the
Assignor for the payment of minimum or base rent or any additional rent due
under the Lease or for the performance of any other obligations to be performed
by the Assignor under the Lease.

inure to the benefit of the parties hereto, and their respective heirs,

shall not be construed to permit any future assignments of the Lease or
subletting of the Premises except as permitted by the Lease.

so executed, shall constitute a binding agreement.

          7. Governing Law. This Assignment shall be governed by and construed
in accordance with the laws of the state in which the Premises are located.

                                     LEASE


                 LEASE, dated as of May 5, 1995, between UNISYS CORPORATION, a
Delaware corporation having an office at Township Line and Union Meeting Roads,
Blue Bell, Pennsylvania 19424 ("Lessor") and LORAL CORPORATION, a New York
corporation having an office at 600 Third Avenue, New York, New York 10016
("Lessee").

                             W I T N E S S E T H :

                 WHEREAS, Lessor is the owner of the real property, including
improvements thereon (collectively, the "Property") referenced on Schedule A
hereto; and

                 WHEREAS, Lessor desires to lease to Lessee, and Lessee desires
to hire from Lessor, certain premises at the Property upon the terms and
conditions hereinafter set forth;

                 NOW, THEREFORE, in consideration of the mutual covenants
hereinafter provided, Lessor and Lessee hereby agree as follows:

                 1.  Demised Premises.

                 1.1. Lessor hereby leases to Lessee, and Lessee hereby leases
and hires from Lessor, the Demised Premises, as defined in Schedule B hereto,
together with the non-exclusive right to use the common areas of the Property
and such other rights as are necessary or desirable to provide Sublessee with
substantially the same rights and benefits as have been generally afforded to
and enjoyed by the Defense Systems unit of Unisys Corporation ("Defense
Systems") prior to the date hereof (including, without limitation, rights of
ingress and egress, parking consistent with past practice or otherwise as set
forth in the Rider attached to this Sublease, and access to public and private
utilities) for the lease term hereinafter stated and for the Base Rent and
Additional Rent (both as hereinafter defined) set forth herein, upon and
subject to all of the terms and provisions hereinafter provided or incorporated
in this Lease by reference.

                 1.2. Lessee agrees to accept the Demised Premises on the
Commencement Date (as hereinafter defined) in its "as is" condition and Lessor
shall not be obligated to perform any work or furnish any materials in, to or
about the Demised Premises in order to prepare the Demised Premises for
occupancy by Lessee or otherwise. Lessee hereby releases Lessor from any and
all liability resulting from (i) any latent or patent defects in the Demised
Premises, (ii) the failure of the Demised Premises to comply with any legal
requirements applicable thereto or (iii) the status of the title to the Demised
Premises, provided that the foregoing release of liability is not intended to
limit or otherwise affect any liability that Lessor or any affiliate of Lessor
may have to Lessee or any affiliate of Lessee which arises under any of the
other terms and conditions of this Lease or under the terms and conditions of
any other agreement. Lessee acknowledges that, except as expressly set forth
herein or as expressly set forth in any separate document, Lessor has made no
statements, representations, covenants or warranties with respect to (x) the
condition or manner of construction of the Property or any improvements
constructed in the Demised Premises, (y) the uses or purposes for which the
Demised Premises may be lawfully occupied or (z) any encumbrances, covenants,
restrictions or agreements affecting title

                                       15

<PAGE>

to the Property or the Demised Premises. Lessee also agrees that, in executing
this Lease, it has not relied upon or been induced by any statements,
representations, covenants or warranties of any person other than those, if
any, set forth expressly in this Lease or in any other separate agreements by
or between Lessor and/or Lessee or any of their respective affiliates.

                 2.  Term.

                 2.1. (a) The term of this Lease shall commence on the date
hereof (the "Commencement Date") and, unless earlier terminated or extended as
herein provided, shall expire on the Expiration Date. As used in this Lease,
(i) "Term" shall mean the term of this Lease, and (ii) "Expiration Date" shall
mean the Scheduled Expiration Date, as defined in Schedule C hereto; provided
that in the event of a termination of this Lease pursuant to the terms hereof
prior to the Scheduled Expiration Date, the "Expiration Date" shall mean such
date of termination of this Lease.

                 (b) References in this Lease to the "termination" of this
Lease include the stated expiration of the Term and any earlier termination
thereof pursuant to the provisions of this Lease, or by law. Except as
otherwise expressly provided in this Lease with respect to those obligations of
Lessee which by their nature or under the circumstances can only be, or under
the provisions of this Lease may be, performed after the termination of this
Lease, the Term and estate granted hereby shall end at noon on the date of
termination of this Lease as if such date were the Expiration Date, and neither
party shall have any further obligation or liability to the other after such
termination. Notwithstanding the foregoing, any liability of Lessor or Lessee
to make any payment under this Lease, including, without limitation, amounts
payable by Lessee as Base Rent or Additional Rent hereunder (both as
hereinafter defined), which shall have accrued prior to the termination of this
Lease shall survive the termination of this Lease.

                 3.  Rent.

                 3.1.  The rent ("Rent") payable during the Term under this
Lease shall consist of the following:

                 (a)  the Base Rent, as defined in Schedule C hereto.

                 (b) additional rent ("Additional Rent") in an amount equal to
any and all other sums payable by Lessee to Lessor under this Lease.

                 3.2. Except as otherwise specifically provided in this Lease
(a) all payments of Base Rent shall be in equal monthly installments and shall
be made in advance on the first (1st) day of each month during the Term,
without notice (provided that if the amount of Base Rent is required to be
calculated by Lessor in accordance with Schedule C hereof, then Lessor shall
give Lessee prior written notice of such calculation, which notice shall
include an explanation of the basis for such calculation and reasonable backup
documentation relating thereto), and (b) all payments of Additional Rent shall
be made within 30 days after written notice from Lessor, in each case by check
payable to the order of "UNISYS CORPORATION" and addressed to Unisys
Corporation, P.O. Box 500, Blue Bell, Pennsylvania 19424-0003, Attention:
Disbursement & Control Dept., or to such other person or at such other place as
Lessor may from time to time designate in writing.

                                       16

<PAGE>

                 3.3. Lessee shall pay all Rent when due, in lawful money of
the United States which shall be legal tender for the payment of all debts,
public and private, at the time of payment. All sums due and payable by Lessor
or Lessee pursuant to the terms of this Lease that are not paid within five (5)
days of the due date therefor shall from and after the due date bear interest
at an annual percentage rate of ten percent (10%). All interest accrued and
payable by Lessee under this subsection as hereinabove provided shall be deemed
to be Additional Rent payable hereunder and due at such time or times as the
rent with respect to which such interest shall have accrued shall be payable
under this Lease.

                 3.4. Lessee agrees to pay, an Additional Rent, any revenue tax
or charge, occupancy tax, business privilege tax, business use tax or any other
tax that may be levied against the Demised Premises or Lessee's use or
occupancy thereof during the Term; provided, however, that in no event shall
Lessee be obligated to pay any income tax that is imposed upon and/or payable
by Lessor, and provided further that payments made by Lessee pursuant to this
Section 3.4 shall not be duplicative of amounts paid by Lessee pursuant to any
other provision of this Lease.

                 3.5. In the event that Lessee shall dispute any calculation of
Rent charged to Lessee by Lessor, then Lessee shall send to Lessor a written
notice, within 30 days of receipt by Lessee of such charge, setting forth the
basis for Lessee's dispute. Lessor and Lessee shall thereupon use reasonable
and good faith efforts to resolve such dispute. If the parties are unable to
resolve such dispute within 30 days after submission by Lessee of its dispute
notice, then the parties shall designate an independent certified public
accountant mutually acceptable to both parties (the "Independent Accountant")
to resolve such dispute and the fees and charges of the Independent Accountant
shall be shared equally by the parties. Both parties shall provide the
Independent Accountant with all information reasonably requested by the
Independent Accountant in connection with its review of such dispute, and both
parties shall request that the Independent Accountant complete its work
expeditiously and issue a written report to both parties setting forth its
determination. The written determination of the Independent Accountant shall be
final and shall be binding upon both Lessor and Lessee. All disputes to be
resolved pursuant to this Section 3.5 shall be so resolved in accordance with
the principles and standards set forth in Section 3.6 below.

                 3.6. All calculations by Lessor of Base Rent, Additional Rent
and any other amounts that are payable by Lessee hereunder shall be made in
accordance with Lessor's past practices during calendar year 1994 with respect
to Defense Systems, and all charges and allocations relating to the Demised
Premises and all accounting practices utilized by Lessor with respect to
amounts charged to Lessee under this Lease (including the capitalization,
amortization and expensing of costs incurred and funds expended) shall also be
made in such manner.

                 4.  Use.

                 4.1. Lessee shall occupy and use the Demised Premises solely
for manufacturing, light assembly, engineering, research and development,
office and warehouse and such other uses as may be approved by Lessor (which
approval shall not be unreasonably withheld, delayed or conditioned), provided
that any such use shall be subject in all respects to the other terms and
provisions of this Lease, and subject to any and all

                                       17

<PAGE>

laws, statutes, ordinances, orders, regulations and requirements of all
federal, state and local governmental, public or quasi-public authorities,
whether now or hereafter in effect, which may be applicable to or in any way
affect the Demised Premises or any part thereof and all requirements,
obligations and conditions of all instruments of record on the date of this
Lease affecting the Demised Premises (collectively, "Legal Requirements").

                 5.  Services.

                 5.1. It is the intent of the parties that Lessor shall
continue to provide to Lessee all services generally and customarily provided
by Unisys Corporation to the occupants of the Demised Premises prior to the
Commencement Date, together with any other services that may be appropriate
under the circumstances from time to time (such services being hereinafter
referred to collectively as the "Services"). In connection with the foregoing,
such Services shall include, without limitation, each of the services set forth
on Schedule D hereto, and such Services shall not include any of those items
set forth on Schedule D-1 hereto. Lessee shall pay to Lessor, in consideration
for the Services and as Additional Rent, an amount equal to Lessor's actual
costs in, to or for the benefit of the Demised Premises or Lessee which shall
be determined in accordance with the principles set forth in Section 3.6 above
("Actual Costs"). On a quarterly basis, Lessor shall provide to Lessee a
written statement, in reasonable detail, setting forth such Actual Costs for
Services. In the event that Lessee disputes Lessor's statement of Actual Costs,
such dispute shall be resolved in accordance with Section 3.5 hereof.

                 5.2. It is the intent of the parties that Lessee shall
continue to provide to Lessor, during the Term hereof, all reasonable services
generally and customarily provided by Defense Systems, prior to the
Commencement Date, to any other portions of the Property. Lessee shall perform
such services, and Lessor shall pay to Lessee a proportionate share of Lessee's
actual costs incurred in performing such services. On a quarterly basis, Lessee
shall provide to Lessor a written statement, in reasonable detail, setting
forth such costs. In the event of a dispute with respect to such costs, such
dispute shall be resolved in accordance with Section 3.5 hereof.

                 5.3. In the event that telephone switching equipment or other
telecommunications equipment utilized by Lessor or Lessee is located within the
premises occupied by the other party, then the party occupying such premises
shall grant the other party reasonable access to such telephone switching
equipment or other telecommunications equipment and other areas reasonably
required for such telecommunications use, subject in each case to reasonable
security requirements of the party granting such access.

                 5.4. The provisions of this Section shall survive the
expiration or earlier termination of this Lease.

                 6.  Alterations; Demising Costs; Signage.

                 6.1. As used herein, the term "Alterations" shall mean,
collectively, any alterations, modifications installations, additions or
improvements to the Demised Premises. Without the prior written consent of
Lessor in each instance, which consent shall not be unreasonably withheld
conditioned or delayed, Lessee shall not make any (a) structural Alterations or
(b) non-structural Alterations having a design and construction cost in

                                       18

<PAGE>

excess of $50,000 on a per project basis. Any Alterations consented to by
Lessor, or otherwise permitted under this Lease, shall be performed by Lessee,
at its sole cost and expense, in a good and workmanlike manner. Lessor shall
have the right to post notices of non-responsibility and similar notices, as
Lessor shall reasonably deem appropriate, on the Demised Premises while
Alterations are occurring.

                 6.2. Lessor and Lessee shall use reasonable and good faith
efforts to reach a mutual agreement as to whether any Alterations are necessary
and appropriate in order to separate the Demised Premises from the premises in
the Property occupied by Lessor. In the event that the parties reach such a
mutual agreement, then Lessor shall perform such agreed upon Alterations, and
Lessee shall, within 30 days after written demand by Lessor, reimburse Lessor
for one-half of the costs and expenses relating to such Alterations. Lessor may
request payment of Lessee's share of such costs, and (if requested) Lessee
shall pay its share of such costs, as such costs are incurred by Lessor during
the course of design and construction of such Alterations. Lessor shall require
that (a) any contractors or subcontractors performing any such work maintain
reasonable and appropriate liability insurance and (b) any such insurance
policies shall name Lessor and Lessee as additional insureds.

                 6.3. Lessee shall have the right to install reasonable and
appropriate signage, both at the entrance to the Demised Premises and in the
common areas of the Property, indicating Lessee's occupancy of the Demised
Premises, provided that the location, size and design of any such signage shall
be subject to the prior written consent of Lessor, which consent shall not be
unreasonably withheld or delayed.

                 6.4. In the event that the Demised Premises are measured or
re-measured pursuant to the terms of this Lease (inclusive of the Rider, if
any, and Schedule's attached hereto), Lessor and Lessee shall each pay one-half
(1/2) of the costs and expenses relating to such measurement or remeasurement.

                 7.  Maintenance and Repair.

                 7.1. Except as provided to the contrary in Schedule D and
Schedule D-1 attached hereto, Lessor shall, at its sole cost and expense,
maintain the Premises in reasonably satisfactory repair and condition, except
for ordinary wear and tear, and will make all structural and nonstructural
repairs which may be required by law or required to keep the Premises in
reasonably satisfactory repair and condition, except for ordinary wear and
tear, and Lessor's Actual Costs for providing such maintenance and repair
Services shall be charged to Lessee as Additional Rent in accordance with
Section 5.1 hereof.

                 8.  Insurance.

                 8.1. Lessee, at Lessee's sole expense, shall maintain for the
benefit of Lessor such policies of insurance (and in such form) with respect to
the Demised Premises which shall be reasonably satisfactory to Lessor as to
coverage and insurer (who shall be licensed to do business in the State in
which the Demised Premises are located) provided that such insurance shall at a
minimum include comprehensive general liability insurance protecting and
indemnifying Lessor and Lessee against any and all claims and liabilities for
injury or damage to persons or property occurring

                                       19

<PAGE>

upon, in or about the Demised Premises, and the public portions of the
Property, caused by or resulting from or in connection with any act or omission
of Lessee or Lessee's employees, agents or invitees. Lessor shall be named as
an additional insured under any such policies of insurance obtained by Lessee,
and no such policy shall be subject to termination or modification unless at
least thirty (30) days' prior written notice (or ten (10) days' prior written
notice, if such termination results from Lessee's failure to pay the premiums
for such insurance) shall have been given by the applicable insurance company
to Lessor. Upon execution of this Lease by Lessee and at least thirty (30) days
prior to the expiration date of such policies, Lessee shall furnish to Lessor a
certificate or certificates of insurance confirming that the required insurance
is in full force and effect with all premiums paid current. Nothing contained
herein shall limit, or prohibit, Lessee from providing such coverage through
"blanket" policies of insurance and/or self-insuring therefor in a manner that
is consistent with the general corporate practices of Lessee.

                 8.2. Nothing contained in this Lease shall relieve Lessee from
any liability as a result of damage from fire or other casualty, but each party
shall look first to any insurance in its favor before making any claim against
the other party for recovery for loss or damage resulting from fire or other
casualty. To the extent that such insurance is in force and collectible and to
the extent permitted by law, Lessor and Lessee each hereby releases and waives
all right to recovery against the other or anyone claiming through or under the
other by way of subrogation or otherwise. The foregoing release and waiver
shall be in force only if the insurance policies of Lessor and Lessee provide
that such release or waiver does not invalidate the insurance; each party
agrees to use reasonable efforts to include such a provision in its applicable
insurance policies. If the inclusion of said provision would involve an
additional expense, either party, at its sole expense, may require such
provision to be inserted in the other's policy.

                 9.  Assignment, Subletting and Encumbrances.

                 9.1. Lessee shall not sublease or mortgage, pledge or
otherwise encumber all or any part of the Demised Premises, assign or mortgage
this Lease (by operation of law or otherwise) or permit the Demised Premises to
be used or occupied by anyone other than Lessee, Lessee's divisions and other
Affiliates and Lessee's licensees, invitees, customers and vendors, without the
prior written consent of Lessor in each instance, which consent shall not be
unreasonably withheld, conditioned or delayed; provided, however, that Lessee,
upon at least 30 days' prior written notice to Lessor, may assign this Lease or
sublet all or part of the Demised Premises to (A) an Affiliate of Lessee, (B)
an entity into which Lessee is merged or consolidated, and (C) an entity which
acquires all or substantially all of the business or operations of Lessee. Any
consent by Lessor as hereinabove required shall not excuse Lessee from its
obligation to obtain the express written consent of Lessor to any further
action or matter with respect to which the consent of Lessor is hereinabove
required and Lessee shall not be released from any of its obligations
hereunder. The term "Affiliate", as used in this Section 9.1, shall have the
same meaning as is set forth in the Asset Purchase Agreement.

                 10.  Liens.

                 10.1.  Lessee shall not suffer or permit any mechanic's,
materialman's, vendor's, supplier's, laborer's or other similar liens

                                       20

<PAGE>

(collectively, "mechanic's liens") to be filed against the Demised Premises, or
any part thereof, nor against Lessee's interest therein, by reason of work,
labor, services or materials supplied or claimed to have been supplied to
Lessee (except for mechanic's liens for payments that are not yet delinquent or
for payments that Lessee is contesting in good faith and in a diligent manner).
If any mechanic's lien described in the preceding sentence shall at any time be
filed against the Demised Premises, or any part thereof, or Lessee's interest
therein, Lessee shall, within forty-five (45) days after notice of the filing
thereof, cause the same to be discharged of record by payment, deposit, bond,
order of a court of competent jurisdiction or otherwise, or provide Lessor with
reasonable assurances as to Lessee's ability to satisfy such lien. If Lessee
shall fail to cause such lien to be discharged within such forty-five (45) day
period, then, in addition to any other right or remedy of Lessor, Lessor may,
but shall not be obligated to, discharge the same either by paying the amount
claimed to be due or by procuring the discharge of such lien by deposit or by
bonding proceedings, and in any such event Lessor shall be entitled to
reimbursement from Lessee for any reasonable costs expended by Lessor.

                 11.  Default.

                 11.1.  (a)  Each of the following shall constitute an Event
of Default hereunder:

                      (i)   if Lessee shall fail to pay when due any Rent or
any other amount Lessee may be required to pay hereunder, and Lessee shall fail
to remedy such default within seven (7) business days after written notice
thereof has been given to Lessee by Lessor, provided that an Event of Default
shall not be deemed to have occurred hereunder if Sublessee shall have timely
disputed in good faith its obligation to pay such Rent or the amount thereof;
or

                      (ii)  if Lessee shall default in the observance or
performance of any term, covenant or condition of this Lease on Lessee's part
to be observed, performed or complied with (other than the payment of Base Rent
and Additional Rent and other amounts payable hereunder) and Lessee shall fail
to remedy such default within thirty (30) days after written notice to cure,
or, if such default is of such a nature that for reasons beyond Lessee's
control it cannot be completely remedied within said period of thirty (30)
days, then if Lessee (A) shall not promptly institute and thereafter diligently
prosecute to completion all steps necessary to remedy the same and (B) shall
not remedy the same within a reasonable time after the date of default; or

                    (iii) if any event shall occur or any contingency shall
arise whereby this Lease or the estate hereby granted or the unexpired balance
of the Term would, except as expressly permitted herein, by operation of law or
otherwise, devolve upon or pass to any person or entity other than Lessee, and
Lessee shall fail to remedy such default within sixty (60) days after written
notice thereof has been given to Lessee by Lessor;

                 (b) Upon the occurrence of any such Event of Default, Lessor
may, in addition to exercising any other available rights or remedies available
to Lessor under law, give to Lessee notice of its intention to end the Term at
the expiration of three (3) days from the date of the giving of such notice,
and, in the event such notice is given, this Lease and the Term and estate
hereby granted (whether or not the Term shall have commenced)

                                       21

<PAGE>

shall terminate upon the expiration of said three (3) days with the same force
and effect as if that day were the Expiration Date, provided, however, that
Lessor and Lessee shall remain liable for the performance of their respective
obligations hereunder which survive the termination of this Lease and for
damages as provided in this Lease.

                 11.2. Notwithstanding anything to the contrary set forth
herein, this Lease shall immediately terminate if any of the following events
shall occur with respect to Lessee: (a) if Lessee shall (i) have applied for or
consented to the appointment of a receiver, trustee or liquidator, or other
custodian of Lessee, or any of its properties or assets, (ii) have made a
general assignment for the benefit of creditors, (iii) have commenced a
voluntary case for relief as a debtor under the United States Bankruptcy Code,
or any other applicable federal or state laws, or filed a petition to take
advantage of any bankruptcy, reorganization, insolvency, readjustment of debts,
dissolution or liquidation law or statute or an answer admitting the material
allegations of a petition filed against it in any proceeding under any such
law, or (iv) be adjudicated a bankrupt or insolvent; or (b) if without the
acquiescence or consent of Lessee, an order, judgment or decree shall have been
entered by any court of competent jurisdiction approving as properly filed a
petition seeking relief under the United States Bankruptcy Code, or any other
applicable federal or state laws, or any bankruptcy, reorganization,
insolvency, readjustment of debts, dissolution or liquidation law or statute
with respect to Lessee, or all or a substantial part of their respective
properties or assets, and such order, judgment or decree shall have continued
unstayed and in effect for any period of not less than ninety (90) days.
Neither Lessee, nor any person claiming through or under Lessee or by reason of
any statute or order of court shall, after such termination, be entitled to
possession of the Demised Premises but shall forthwith quit and surrender the
Demised Premises. Without limiting any of the foregoing provisions of this
Section 10.2, if pursuant to the United States Bankruptcy Code, or any other
applicable federal or state laws, Lessee is permitted to assign this Lease,
Lessee agrees that adequate assurance of future performance by an assignee
expressly permitted under such law shall be deemed to mean evidence in the form
of financial statements prepared and certified by a certified public accountant
that the assignee will have a net worth, after excluding the value of the
leasehold, sufficient to meet the remaining obligations under this Lease.

                 11.3. In the event of any breach by Lessee or any persons
claiming through or under Lessee of any of the terms, covenants or conditions
contained in this Lease, Lessor, after the giving of any notice required by the
terms of this Lease and the expiration of any notice and cure periods
hereunder, (a) shall be entitled to enjoin such breach and (b) shall have the
right to invoke any right and remedy available at law or in equity or by
statute or otherwise. The provisions of this Section 11.3 shall survive the
expiration or sooner termination of this Lease.

                 11.4. If this Lease and the Term shall terminate as provided
in Section 11.1 or in Section 11.2 above, or by or under any summary proceeding
or any other action or proceeding or if Lessor shall re-enter the Demised
Premises as hereinabove provided or by or under any summary proceeding or any
other action or proceeding, then in any of said events:

                 (a) Lessee shall pay to Lessor all Base Rent, Additional Rent
and other amount payable by Lessee hereunder to the date upon which this

                                       22

<PAGE>

Lease and the Term shall have terminated or to the date of re-entry upon the
Demised Premises by Lessor, as the case may be;

                 (b) Lessor shall be entitled to retain all monies, if any,
paid by Lessee to Lessor, whether as advance Rent, security or otherwise, but
such monies shall be credited by Lessor against any Rent due at the time of
such termination or re-entry or, at Lessor's option, against any damages
payable by Lessee;

                 (c) Lessee shall be liable for and shall pay to Lessor, as
damages, any deficiency between the Base Rent and Additional Rent payable
hereunder for the period which otherwise would have constituted the unexpired
portion of the Term (conclusively presuming the Base Rent and Additional Rent
to be at the same rate as was payable for the year immediately preceding such
termination or re-entry less any Additional Rent for such one-year period
payable to Lessor by Lessee pursuant to Section 5.1 above) and the net amount,
if any, of rents ("Net Rent") collected under any reletting effected by Lessor
for any part of such period (after first deducting from the rents collected
under any such reletting all of Lessor's reasonable expenses in connection with
the termination of this Lease or Lessor's re-entry upon the Demised Premises
and in connection with such reletting including all reasonable repossession
costs, brokerage commissions, legal expenses, attorneys' fees, alteration or
similar costs and other expenses of preparing the Demised Premises for such
reletting);

                 (d) In the event that Lessor shall not have collected any
monthly deficiencies as aforesaid, Lessor shall be entitled to recover from
Lessee, and Lessee shall pay to Lessor, on demand, as and for liquidated and
agreed final damages, a sum equal to the amount by which the Base Rent and
Additional Rent payable hereunder for the period which otherwise would have
constituted the unexpired portion of the Term (conclusively presuming the Base
Rent and Additional Rent to be at the same rate as was payable for the year
immediately preceding such termination or re-entry less any Additional Rent for
such one-year period payable to Sublessor by Sublessee pursuant to Section 5.1
above) exceeds the then fair and reasonable rental value of the Demised
Premises for the same period, both discounted to present value at the rate of
eight percent (8%) per annum. If before presentation of proof of such
liquidated damages to any court, commission or tribunal, the Demised Premises,
or any part thereof, shall have been relet by Lessor for the period which
otherwise would have constituted the unexpired portion of the Term, or any part
thereof, the amount of rent upon such reletting shall be deemed, prima facie,
to be the fair and reasonable rental value for the part or the whole of the
Demised Premises so relet during the term of the reletting; and

                 (e) In no event shall Lessee be entitled to receive any excess
of Net Rent over the sums payable by Lessee to Lessor hereunder, and in no
event shall Lessee be entitled in any suit for the collection of damages
pursuant to this Article to a credit in respect of any Net Rent from a
reletting except to the extent actually received by Lessor prior to the
commencement of such suit.

                 11.5. If a default by Lessee shall have occurred and be
continuing with respect to any obligations of Lessee under this Lease, Lessor
may, at its option, upon reasonable prior notice to Lessee (unless Lessor
reasonably believes there to be an emergency threatening Lessor's property
outside the Demised Premises, or threatening substantial damage to Lessor's
interest in the Demised Premises as Lessor, in which event no notice shall be

                                       23

<PAGE>

required and Lessor may act immediately), perform such obligations for the
account of, and at the expense of, Lessee. The sums so paid or incurred by
Lessor, in its sole discretion, together with interest at the rate specified in
Section 3.3 hereof, costs and damages shall be due from and paid by Lessee, as
Additional Rent, upon Lessee's receipt of written demand therefor from Lessor.

                 11.6. Nothing herein contained shall be construed as limiting
or precluding the recovery by Lessor against Lessee of any sums or damages to
which, in addition to the damages particularly provided above, Lessor may
lawfully be entitled by reason of any default hereunder on the part of Lessee;
provided, however, that in no event shall Lessor or Lessee be entitled to
special or consequential damages with respect to any matter arising hereunder
or relating hereto.

                 12.  Indemnification.

                 12.1. Lessee shall indemnify and hold harmless Lessor and its
employees and agents from and against any and all loss, cost, liability, claim,
damage and expense, including, without limiting the generality of the
foregoing, reasonable attorneys' fees and expenses and court costs, penalties
and fines incurred in connection with or arising from any injury to Lessee or
for any damage to, or loss (by theft or otherwise) of, any of the property of
Lessee, irrespective of the cause of such injury, damage or loss and whether
occurring in or about the Demised Premises or the Property.

                 12.2. Lessee shall indemnify and hold harmless Lessor and its
officers, directors, shareholders and employees from and against any and all
loss, cost, liability, claims, damage and expenses, including, without limiting
the generality of the foregoing, reasonable attorneys' fees and expenses and
court costs, penalties and fines, whether or not due to third party claims,
suits or proceedings, incurred in connection with or arising from (a) any
default by Lessee in the observance or performance of, or compliance with, any
of the terms, covenants or conditions of this Lease on Lessee's part to be
observed, performed or complied with, (b) the use or occupancy or manner of use
or occupancy of the Demised Premises by Lessee or any of its agents, employees
or contractors, or the exercise by Lessee or any of its agents, employees or
contractors, of any rights granted to Lessee hereunder, (c) any acts, omissions
or negligence of Lessee or any of its agents, employees or contractors, in or
about the Demised Premises or the Property either prior to, during, or after
the termination of this Lease or (d) the condition of the Demised Premises, but
only to the extent that Lessee fails to perform any of its obligations
hereunder with respect to the condition of the Demised Premises. If any action
or proceeding shall be brought against Lessor by reason of any such claim,
Lessee shall be given prompt notice thereof and, upon notice from Lessor, shall
resist and defend such action or proceeding at Lessee's sole expense and employ
counsel therefor reasonably satisfactory to Lessor. Lessee shall pay to Lessor
on demand all sums which may be owing to Lessor by reason of the provisions of
this subsection. Lessee's obligations under this subsection shall survive the
Expiration Date or earlier termination of this Lease.

                 12.3. Lessor shall indemnify and hold harmless Lessee and
Lessee's officers, directors, shareholders and employees from and against any
and all loss, cost, liability, claims, damage and expenses, including, without
limiting the generality of the foregoing, reasonable attorneys' fees and
expenses and court costs, penalty and fines, whether or not due to third

                                       24

<PAGE>

party claims, suits or proceedings, incurred in connection with or arising from
(a) any default by Lessor in the observance or performance of, or compliance
with, any of the terms, covenants or conditions of this Lease on Lessor's part
to be observed, performed or complied with, or (b) the gross negligence or
wilful misconduct of Lessor (in its capacity as lessor hereunder) or any of its
agents, employees or contractors (retained by Lessor in its capacity as lessor
hereunder), in or about the Demised Premises or the Property either prior to,
during, or after the termination of this Lease. If any action or proceeding
shall be brought against Lessee by reason of any such claim, Lessor shall be
given prompt notice thereof and, upon notice from Lessee, shall resist and
defend such action or proceeding at Lessor's sole expense and employ counsel
therefor reasonably satisfactory to Lessee. Lessor shall pay to Lessee on
demand all sums which may be owed to Lessee by reason of the provisions of this
subsection. Lessor's obligations under this subsection shall survive the
Expiration Date or earlier termination of this Lease.

                 12.4. Lessor shall not be liable for any loss or damage to
property of Lessee or any of its employees, guests, invitees or licensees by
reason of theft or otherwise. Lessor shall not be liable for any injury or
damage to persons or property resulting from fire, explosion, falling plaster,
steam, gas, electricity, water, rain or leaks from any part of the Demised
Premises or from the pipes, appliances or plumbing works or from the roof,
street or subsurface or from any other place or by dampness or by any other
cause of whatsoever nature, unless such injury or damage has been shown to have
been due solely to the gross negligence or willful act or omission of Lessor,
its affiliates, or the officers, directors, employees or agents of Lessor or
its affiliates in the course of their employment. Subject to the foregoing, all
property of Lessee or others kept or stored on the Demised Premises shall be so
kept or stored at the risk of Lessee only.

                 12.5. Notwithstanding anything in this Section 12 to the
contrary, neither party shall be required to indemnify the other party (an
"indemnitee") against the indemnitee's own negligence or wilful misconduct.

                 13.  Hazardous Materials.

                 13.1. Lessee shall not cause or permit any Hazardous Material
(as hereinafter defined) to be brought upon, kept or used in or about the
Demised Premises by the agents, principals, employees, assigns, sublessees,
contractors, subcontractors, consultants or invitees of Lessee, except in full
compliance with applicable Legal Requirements. If Lessee breaches the
obligations stated in the preceding sentence, or if the introduction or release
of a Hazardous Material on the Demised Premises caused or permitted by Lessee
(or the aforesaid others) results in contamination of the Demised Premises or
any surrounding area(s), or if contamination of the Demised Premises or any
surrounding area(s) by Hazardous Material otherwise occurs for which Lessee is
legally, actually or factually liable or responsible (other than liability
which arises solely as a result of the tenancy created hereby or solely as a
result of Lessor's mere occupancy of the Demised Premises), then Lessee shall
fully and completely indemnify, defend and hold harmless Lessor (or any party
claiming by, through or under Lessor) from any and all claims, judgments,
damages, penalties, fines, costs, liabilities, expenses or losses, including,
without limitation: (i) diminution in the value of the Demised Premises; (ii)
any asserted damage to the Property or to neighboring properties or the
occupants of the Property or neighboring properties, and (iii) any sums paid in
settlement of claims,

                                       25

<PAGE>

reasonable attorneys' fees, consultants fees and expert fees which arise or
arose before, during or after the term of this Lease as a consequence of such
contamination. This indemnification includes, without limitation, costs
incurred in connection with any investigation or site conditions or any
clean-up, remedial, removal or restoration work required by any federal, state
or local governmental agency or political subdivision because of Hazardous
Materials present in the soil or ground water on or under the Demised Premises
for which Lessee is responsible pursuant to the terms of this Lease. Without
limiting the foregoing, if the introduction or release of any Hazardous
Materials on, under or about the Demised Premises or any other surrounding
area(s) caused or permitted by Lessee (or the aforesaid others) results in any
contamination of the Demised Premises, Lessee shall immediately take all
actions at its sole expense as are necessary or appropriate to return the
Demised Premises to the condition existing prior to the introduction by Lessee
of any such Hazardous Materials thereto; provided that the prior written
approval (which approval shall not be unreasonable withheld, conditioned or
delayed) of such actions by Lessor shall be first obtained. The foregoing
obligations and responsibilities shall survive the expiration or earlier
termination of this Lease.

                 13.2. As used herein, the term "Hazardous Materials" means any
hazardous or toxic substance, material or waste, including, but not limited to,
those substances, materials, and wastes listed in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended by
the Superfund Amendments and Reorganization Act of 1986 (42 U.S.C. Section 9601
et seq., as amended), the Federal Clean Water Act, the Federal Clean Air Act,
the Federal Resource Conservation and Recovery Act, the Federal Toxic
Substances Control Act, the United States Department of Transportation
Hazardous Materials Table (49 CFR 172.101) or by the Environmental Protection
Agency as hazardous substances (40 CFR Part 301 and amendments thereto), and
all substances, materials and wastes that are defined as "toxic", "hazardous"
or "extremely hazardous" or are otherwise regulated under any applicable local,
state or federal law. In furtherance of, and not in limitation of the
foregoing, the term "Hazardous Materials" shall include asbestos,
asbestos-containing materials and petroleum.

                 13.3. Lessor and Lessee acknowledge and agree that the Asset
Purchase Agreement shall govern all matters relating to the presence of
Hazardous Materials in, on, under and about the Demised Premises prior to the
execution and delivery hereof.

                 14.  Right to Inspect.

                 14.1. Lessor and the authorized representatives of Lessor
shall have the right to enter upon the Demised Premises upon reasonable advance
notice to Lessee at all reasonable times during usual business hours (and at
any time without notice in the case of an emergency) for the purpose of
inspecting the same, conducting an environmental review of Lessee's business
operations or exhibiting the same to prospective purchasers, tenants or
mortgagees.

                 15.  Eminent Domain.

                 15.1. If all of the Demised Premises are taken by exercise of
the power of eminent domain (or conveyed by Lessor in lieu of such exercise)
this Lease will terminate on a date (the "termination date") which

                                       26

<PAGE>

is the earlier of the date upon which the condemning authority takes possession
of the Demised Premises or the date on which title to the Demised Premises is
vested in the condemning authority. If more than 25% of the rentable area of
the Demised Premises is so taken, or if Lessee's rights of access to the
Demised Premises or Lessee's use of parking facilities at the Property are
materially impaired as a result of such a taking, then Lessee will have the
right to cancel this Lease by written notice to Lessor given within 20 days
after the termination date. If less than 25% of the rentable area of the
Demised Premises is so taken, or if the Lessee does not cancel this Lease
according to the preceding sentence, the Base Rent will be abated in the
proportion of the rentable area of the Demised Premises so taken to the
rentable area of the Demised Premises immediately before such taking, and
Lessee's Share will be appropriately recalculated. If 25% or more of the
Property is so taken, Lessor may cancel this Lease by written notice to Lessee
given within 30 days after the termination date. In the event of any such
taking, the entire award will be paid to Lessor and Lessee will have no right
or claim to any part of such award; however, Lessee will have the right to
assert a claim against the condemning authority in a separate action, so long
as Lessor's award is not otherwise reduced, for Lessee's moving expenses and
leasehold improvements owned by Lessee.

                 16.  Damage and Destruction.

                 16.1. If the Demised Premises or the Property are damaged by
fire or other insured casualty, Lessor will give Lessee written notice of the
time which will be needed to repair such damage, as determined by Lessor in its
reasonable judgment, and the election (if any) which Lessor has made according
to this Section 16. Such notice will be given before the 30th day (the "notice
date") after the fire or other insured casualty.

                 16.2. If the Demised Premises or the building are damaged by
fire or other insured casualty to an extent which may be repaired within 120
days after the notice date, as reasonably determined by Lessor, Lessor will
promptly begin to repair the damage after the notice date and will diligently
pursue the completion of such repair. In that event this Lease will continue in
full force and effect except that Base Rent and (as appropriate) Additional
Rent will be abated on a pro rata basis from the date of the damage until the
date of the completion of such repairs (the "repair period") based on the
proportion of the rentable area of the Demised Premises that Lessee is unable
to use during the repair period.

                 16.3. If the Demised Premises or the Property are damaged by
fire or other insured casualty to an extent that may not be repaired within 120
days after the notice date, as reasonably determined by Lessor, then (a) Lessor
may cancel this Lease as of the date of such damage by written notice given to
Lessee on or before the notice date or (b) Lessee may cancel this Lease as of
the date of such damage by written notice given to Lessor within 10 business
days after Lessor's delivery of a written notice that the repairs cannot be
made within such 120-day period. If neither Lessor nor Lessee so elects to
cancel this Lease, Lessor will diligently proceed to repair the Property and
the Demised Premises, and Base Rent and (as appropriate) Additional Rent will
be abated on a pro rata basis during the repair period based on the proportion
of the rentable area of the Demised Premises that Lessee is unable to use
during the repair period.

                 16.4.  Notwithstanding the provisions of this Section 16, if
a material portion of the Demised Premises or the Property is damaged by an

                                       27

<PAGE>

uninsured casualty, or if the proceeds of insurance are insufficient to pay for
the repair of any material damage to the Demised Premises or the Property,
Lessor will have the option to repair such damage or cancel this Lease as of
the date of such casualty by written notice to Lessee on or before the notice
date, provided, however, that such termination shall not be effective if
Lessee, within 10 days after its receipt of such notice, delivers to Lessor the
written agreement of Lessee (in form and substance reasonably satisfactory to
Lessor) to pay or reimburse Lessor for the uninsured portion of the cost of
such repairs.

                 16.5. If any such damage by fire or other casualty is the
result of the negligence or wilful misconduct of Lessee, its agents,
contractors, employees, or invitees, there will be no abatement of Base Rent or
Additional Rent as otherwise provided for in this Section 16. Lessee will have
no rights to terminate this Lease on account of any damage to the Demised
Premises or the Property except as set forth in this Lease.

                 17.  Remedies Cumulative.

                 17.1. Each right and remedy of Lessor under this Lease shall
be cumulative and be in addition to every other right and remedy of Lessor
under this Lease and now or hereafter existing at law or in equity, by statute
or otherwise.

                 18.  Quiet Enjoyment.

                 18.1. Lessor covenants that, as long as Lessee shall pay the
Base Rent and Additional Rent and all other amounts Lessee shall be required to
pay hereunder and shall duly observe, perform and comply with all of the terms,
covenants and conditions of this Lease on its part to be observed, performed or
complied with, Lessee shall, subject to all of the terms of this Lease,
peaceably have, hold and enjoy the Demised Premises during the Term without
molestation or hindrance by Lessor.

                 19.  Release of Lessor.

                 19.1. The term "Lessor", as used in this Lease so far as
covenants or obligations on the part of Lessor are concerned, shall be limited
to mean and include only the owner or owners at the time in question of the
Property, and in the event of any transfer or transfers of the fee interest in
the Property, Lessor herein named shall be automatically freed and relieved
from and after the date of such transfer of all liability with respect to the
performance of any covenants or obligations on the part of Lessor contained in
this Lease thereafter to be performed; provided, however, that no Lessor shall
be freed or relieved from any of its obligations or liabilities hereunder which
first arise or accrue prior to the transfer of such Lessor's interest in the
Property.

                 20.  Surrender of Demised Premises.

                 20.1. Lessee shall, no later than the termination of this
Lease and in accordance with all of the terms of this Lease, vacate and
surrender to Lessor the Demised Premises, together with all Alterations, in
similar order, condition and repair as the same were in as of the Commencement
Date, and broom clean, reasonable wear and tear, damages resulting from a
casualty for which Lessee is not responsible, and other items the repair or
remediation of which is the responsibility of Lessor

                                       28

<PAGE>

excepted. Tenant's obligation to observe or perform this covenant shall
survive the termination of this Lease.

                 20.2. Notwithstanding any provision of law or any judicial
decision to the contrary, no notice shall be required to terminate the Term on
the Expiration Date, and the Term shall expire on the Expiration Date without
notice being required from either party. In the event that Lessee remains
beyond the Expiration Date, it is the intention of the parties and it is hereby
agreed that a tenancy at sufferance shall arise at a monthly rent equal to 150%
of the monthly Base Rent in effect at the expiration of the Term. It is further
agreed that Lessee shall indemnify and hold harmless Lessor from and against
any and all liability, claims, demands, expenses, damages and judgments (other
than consequential or special damages) incurred by Lessor as a result of
Lessee's retaining possession, which indemnification obligation shall survive
the Expiration Date.

                 21.  Notices.

                 21.1. All notices, consents, approvals or other communications
(collectively, a "Notice") required to be given under this Lease or pursuant to
law shall be in writing and, unless otherwise required by law, shall be
delivered personally or by overnight courier service or given by registered or
certified mail, return receipt requested, postage prepaid, to the parties at

hereunder and perform all of the other covenants and agreements hereunder on
the part of Lessee to be performed shall in no way be affected, impaired or
excused because Lessor is unable to fulfill any of its obligations under this
Lease expressly or impliedly to be performed by Lessor or because Lessor is
unable to make, or is delayed in making, any repairs, additions, alterations,
improvements or decorations or is unable to supply or is delayed in supplying

separate agreement.

allocated to the Demised Premises. Lessor shall, as soon as practicable after

                        LIMITED NONCOMPETITION AGREEMENT

     This Limited Noncompetition Agreement between Lockheed Martin Corporation
("Lockheed Martin") and L-3 Communications Corporation ("L-3") is dated as of
April 30, 1997 with reference to the following:

                                   Recitals

     WHEREAS, Lockheed Martin, Lehman Brothers Capital Partners III, L.P.,
Frank C. Lanza, Robert V. LaPenta and L-3 Communications Holdings, Inc.
("Holdings") have entered into a Transaction Agreement dated as of March 28,
1997 (as amended by Amendment No. 1 to Transaction Agreement dated as of
April 11, 1997, and as it may be further amended from time to time, the
"Transaction Agreement"); and

     WHEREAS, the Transaction Agreement contemplates that the business and
assets of certain business elements of Lockheed Martin, the Business Units,
will be sold upon the terms and subject to the conditions of the Transaction
Agreement to Holdings; and

     WHEREAS, Section 12.01 of the Transact on Agreement provides that the
obligations of Lockheed Martin, Holdings and the Purchasers to consummate the
Closing are subject to the satisfaction (or waiver) of certain enumerated
conditions one of which (contained with Section 12.01(e)) is that Lockheed
Martin and Holdings shall have executed and delivered the noncompetition
agreement contemplated by Section 9.09 of the Transaction Agreement; and

     WHEREAS, Holdings will conduct the businesses sold to it under the
Transaction Agreement through L-3, a wholly-owned subsidiary of Holdings.

     NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements of the parties contained herein, Lockheed Martin and
L-3 agree as follows:

     1. Capitalized terms used but not defined in this Limited Noncompetition
Agreement shall have the meanings ascribed to them in the Transaction
Agreement.

     2. Subject to the provisions of Paragraph 3, Paragraph 4, Paragraph 5 and
Paragraph 6 hereof, the Lockheed Martin Companies shall not sell products
anywhere in the world in competition with products of L-3 listed on "Attachment
A" hereto, or being supplied as of the Closing Date by the Business in
connection with its Performance of the specific programs listed on "Attachment
A" hereto (collectively, the "competing businesses"), in each instance for the
applications listed opposite the product or program listed on Attachment A and
for a period of three years commencing as of the Closing Date.

     3. The provisions of Paragraph 2 shall prohibit the acquisition by
Lockheed Martin or any of its Affiliates of all or any part of a business or
Person (whether through the acquisition of assets, securities or other
ownership interest, the effecting of a merger, business combination,
reorganization, exchange or recapitalization or other similar transaction)

                                       1

<PAGE>

(the "Acquired Business") with any Person where a primary purpose of the
acquisition is the avoidance of the prohibitions of Paragraph 2. For purposes
of the foregoing, in the case of any such acquisition by Lockheed Martin or any
of its Affiliates where the competing business conducted by the Acquired
Business represents greater than 35% of the revenues of the Acquired Business
for its most recently completed fiscal year, a primary purpose of the
transaction shall be deemed to be the avoidance of the prohibitions of
Paragraph 2. Notwithstanding the provisions of the preceding sentence, the
provisions of Paragraph 2 shall not prohibit the acquisition by Lockheed Martin
or any of its Affiliates of an Acquired Business where the competing business
conducted by the Acquired Business represents greater than 35% of the revenues
of the Acquired Business (a "Disqualifying Acquisition," and the portion of the
Acquired Business that is a competing business being the "Disqualified
Business"), provided that Lockheed Martin or any of its Affiliates offers to
sell and assign the Disqualified Business (and associated liabilities) obtained
and assumed in the Disqualifying Acquisition for cash to L-3 within 90 days of
the consummation of the Disqualifying Acquisition at the fair market value of
such Disqualified Business (and associated liabilities) with the benefit of
substantially similar representations, warranties and indemnification periods
from the fair market value of such Disqualified Business (and associated
liabilities), L-3 and such Lockheed Martin or their representatives shall meet
within 15 days of the date such offer is made and attempt mutually to determine
in good faith such fair market value. If L-3 and Lockheed Martin are unable to
determine a mutually acceptable fair market value within 20 days after their
initial meeting, L-3 and Lockheed Martin shall mutually engage (and share
equally in the fees and expenses of) an investment banking firm to determine
within 20 days of such firm's engagement the fair market value of the
Disqualified Business (and associated liabilities), which determination shall
be binding upon L-3 and Lockheed Martin for purposes of Lockheed Martin's offer
to L-3 as contemplated herein. Lockheed Martin shall not be obligated to keep
its offer to L-3 open for more than 20 days after final determination of the
fair market value of the Disqualified Business and its assumption of the
associated liabilities within 75 days of such acceptance, otherwise Lockheed
Martin and its Affiliates shall be permitted to keep and operate, or divest,
such Disqualified Business (and associated liabilities) in Lockheed Martin's
sole discretion.

     4.   The prohibitions of Paragraph 2 shall not apply to:

          (a)  businesses operated and managed by Lockheed Martin or its
Affiliates on behalf of the U.S. Government; or

          (b) Acquired Businesses where the acquisition is permitted under
Paragraph 3; provided that in the case of any such acquisition (i) the
competing business was being conducted by the Acquired Business as of the
closing of the acquisition of the Acquired Business or (ii) Lockheed Martin or
the Acquired Business can affirmatively demonstrate that the Acquired Business
was considering entering the competing business as of the closing of the
acquisition of the Acquired Business, or (iii) the competing business is
reasonably related to the businesses referenced in either or both of the
preceding clauses (i) or (ii); or

          (c) the acquisition by Lockheed Martin or any of its Affiliates of
not greater than twenty percent of the voting securities of any Person engaged
in a competing business; or

                                       2

<PAGE>

          (d) the acquisition by Lockheed Martin or any of its Affiliates of
any non-voting securities of any Person engaged in a competing business.

     5. Notwithstanding the provisions of Paragraph 2, nothing in this Limited
Noncompetition Agreement shall prevent Lockheed Martin or any of its Affiliates
from:

          (a) continuing to engage without impediment in any business,
including but not limited to the unrestricted sale of products related to that
business, conducted by Lockheed Martin or any of its Affiliates as of Closing
(other than businesses conducted by Lockheed Martin solely through the Business
Units), any such business being hereinafter referred to as an "Existing
Business"; or

          (b) entering into any business and thereafter engaging without
impediment in such business, including but not limited to the unrestricted sale
of products related to that business where Lockheed Martin can affirmatively
demonstrate that, as of the Closing, Lockheed Martin or any of its Affiliates
or any business element thereof (excluding the Business Units) was considering
entering such business, any such business being hereinafter referred to as a
"Planned Business"; or

          (c) entering into any business and thereafter engaging without
impediment in such business, including but not limited to the unrestricted sale
of products related to that business, where such business is reasonably related
to either or both an Existing Business or a Planned Business.

     6. For the purposes of Paragraph 2, the sale by Lockheed Martin or its
Affiliates (including, without limitation, any Acquired Business) of systems
manufactured, assembled, fabricated or integrated by Lockheed Martin or its
Affiliates (which systems may themselves be subsystems or components of larger
systems) where the system manufactured, assembled, fabricated or integrated by
Lockheed Martin or its Affiliates (A) includes as one or more subsystems,
components, subcomponents or other parts of the system products sold by (i) L-3
or (ii) third-party sources other than L-3 or (B) where such system includes as
one or more subsystems, components, subcomponents or other parts of the system
products manufactured, assembled, fabricated or integrated by Lockheed Martin
or its Affiliates shall be deemed not to be a sale in competition with products
sold by L-3 and, therefore, is permitted under Paragraph 2; provided, however,
that, if sale of the product manufactured, assembled, fabricated or integrated
is not permitted by any of the exceptions to Paragraph 2 other than by clause
(B) of this Paragraph 6, then prior to manufacturing the subsystem, component,
subcomponent or other part of the system Lockheed Martin shall in its good
faith business judgment (which may include, but is not limited to,
consideration of the optimum combination of performance, schedule, quality,
cost, customer preference, ability to provide a total solution and/or turnkey
system and other factors considered relevant to the decision by the Lockheed
Martin company making the make/buy decision) consider procuring the item from
L-3 and provided further that items manufactured by Lockheed Martin or any of
its Affiliates in reliance on the exception provided by clause (B) of this
Paragraph 6 may only be sold during the term of this Limited Noncompetition
Agreement as part of a system qualifying for the exception provided by clause
(B) of this Paragraph 6.

     7.   Lockheed Martin acknowledges that in the event of its or its
Subsidiaries' breach of the covenants contained in this Limited

                                       3

<PAGE>

Noncompetition Agreement, money damages would be an inadequate remedy.
Accordingly, without prejudice to the rights of L-3 also to seek such damages
or other remedies available to it, L-3 may seek, and Lockheed Martin shall not
contest the appropriateness of injunctive or other equitable relief in any
proceeding that L-3 may bring to enforce the covenants contained in this
Limited Noncompetition Agreement. No waiver of any breach of the covenants
contained in this Limited Noncompetition Agreement shall be implied from
forbearance or failure of L-3 to take action in respect thereof.

     8. Lockheed Martin and L-3 agree that, if any provision of this Limited
Noncompetition Agreement should be adjudicated to be invalid or unenforceable,
such provision shall be deemed deleted herefrom with respect, and only with
respect, to the operation of such provision in the particular jurisdiction in
which such adjudication was made. To the extent any such provisions may be
valid and enforceable in such jurisdiction by limitations on the scope of the
activities, geographical area or time period covered, L-3 and Lockheed Martin
agree that such provision instead shall be deemed limited to the extent, and
only to the extent, necessary to make such provision enforceable to the fullest
extent permissible under the laws and public policies in such jurisdiction.

     9.   All notices, requests and other communications to any party
hereunder shall be in writing (including telecopy or similar writing) and

   electronic and physical material, registration and system management and 
   audit support. The LMD has been hosted on 486-based personal computers and 
   on the compartmented mode workstation. The KP performs cryptographic 
   functions and electronically transfers keys from the KP to end-user 
   equipment. 

o  Network Security. Information is increasingly becoming the critical 
   competitive advantage in both military and industrial operations. As we 
   become more reliant on the systems that gather and deliver information, we 
   also must become better able to defend these assets against attack. The 
   terms "hacker" and "virus" are relatively recent additions to computer 
   jargon; "information warfare" is a relatively new focus of the DoD. 
   Communications Systems is staying on the cutting edge through numerous 
   research and development efforts, such as: (1) intelligent agents required 
   to analyze a computer network for vulnearability problems and to report 
   the problems to a central controller; (2) a high performance, scaleable

of the Assets (the "Closing") and the assumption of the Assumed Liabilities
shall take place at 10:00 A.M. local time on the 26th day of January, 1998 at
the offices of Whitman Breed Abbott & Morgan LLP, 200 Park Avenue, New York, NY

conditions set forth in this Agreement, Buyer agrees to pay to Seller at the
Closing an aggregate of U.S. $27 million, subject to adjustment as provided for

of the other party.  The parties shall in good faith exercise reasonable
efforts to support such reported allocations in any audit proceedings initiated
by any taxing authority.

extent based on or arising out of or based upon product liability with respect

                 2.6      Consent of Third Parties.  Notwithstanding anything
to the contrary in this Agreement, this Agreement shall not constitute an
agreement to assign or transfer any Governmental Approval, instrument,
contract, lease, permit or other agreement or arrangement or any claim, right
or benefit arising thereunder or resulting therefrom if an assignment or
transfer or an attempt to make such an assignment or transfer without the
consent of a third party would constitute a breach or violation thereof or
affect adversely the rights of Buyer or Seller thereunder; and any transfer or
assignment to Buyer by Seller of any interest under any such Governmental
Approval, instrument, contract, lease, permit or other agreement or arrangement

instrument, contract, lease, permit or other agreement or arrangement on behalf
of Buyer, (iii) cooperate with Buyer in any lawful arrangement to provide that
Buyer shall receive the benefits under any such Governmental Approval,

account of Buyer any rights of Seller arising from such Government Approval,
instrument, contract, lease, permit or other agreement or arrangement, provided
that Buyer shall undertake to pay or satisfy the corresponding liabilities for
the enjoyment of such benefit to the extent Buyer would have been responsible
therefor if such consent or approval had been obtained.  Nothing in this
Section 2.6 shall be deemed a waiver by Buyer of its right to receive an
effective assignment of all of the Assets.

                 2.7      Adjustment of Purchase Price.

                          (a)     Calculation of Adjustment.  The Purchase
Price shall be (i) increased by the amount that the Closing Date Net Assets (as
hereinafter defined), are greater than $25,099,080 (which amount is the book
value of the net assets as shown on the adjusted September Balance Sheet (the
"Target Net Assets"); or (ii) decreased by the amount that the Closing Date Net
Assets are less than the Target Net Assets.  The term "Closing Date Net Assets"
as used herein shall mean the book value of the Assets set forth on the Final
Closing


                                      -8-
<PAGE>

Statement of Net Assets (as hereinafter defined) in excess of the amount of the
Assumed Liabilities set forth on the Final Closing Statement of Net Assets,
determined in accordance with the procedures set forth below.  The amount of
any decrease or increase to the Purchase Price pursuant to this Section 2.7(a)
plus interest from and including the Closing Date to but excluding the date of
payment at the Prime Rate (as hereinafter defined) shall be paid by Seller or
Buyer, as the case may be, by wire transfer in immediately available funds
within five (5) business days after the Final Closing Statement of Net Assets
is agreed to by Seller and Buyer or is determined by the Neutral Auditor (as
hereinafter defined).  For purposes of this Agreement, "Prime Rate" means the
prime rate of interest in effect on the Closing Date as stated in the "Money
Rates" section of the Wall Street Journal.

                          (b)     Preparation of Closing Statement of Net
Assets.  As soon as practicable, and in any event within sixty (60) days after
the Closing Date, Seller shall cause Ernst & Young LLP ("E&Y") to prepare an
audited statement of net assets for the Business consisting of the Assets and
the Assumed Liabilities, as of the close of business on the Closing Date
determined on a pro forma basis as if the parties hereto had not consummated
the transactions contemplated by this Agreement (the "Closing Statement of Net
Assets"), to be prepared in accordance with United States generally accepted
accounting principles ("GAAP") applied on a basis consistent with the September
30, 1997 Financial Statements (including the September Balance Sheet) through
full application of the policies and procedures used in preparing the September
30, 1997 Financial Statements (including the September Balance Sheet) and
taking into account the type of adjustments included in the September Balance
Sheet set forth in Schedule 3.4, and with changes in contract estimates at
completion ("EAC's") and estimates to complete ("ETC's") determined on a basis
consistent with the method used for the determination of the September 30, 1997
Financial Statements (including the September Balance Sheet); provided that,
for purposes of the Closing Statement of Net Assets, the cash and cash
equivalents held in non-US bank accounts for the benefit of the STS Division
shall be transferred to Buyer and shall be reflected as assets of the STS
Division and shall be included in the calculation of any Purchase Price
adjustment required by this Section.  The Closing Statement of Net Assets shall
be accompanied by the report of E&Y thereon and by a certificate of Seller's
Chief Financial Officer, each of which shall state that the Closing Statement
of Net Assets presents fairly, in all material respects, the Assets and Assumed
Liabilities presented on such statement as provided for in this Agreement at
the Closing Date in conformity with GAAP consistently applied with the
September 30, 1997 Financial Statements, except that it does not contain all
the notes required by GAAP.  Buyer shall provide Seller, E&Y and the Neutral
Auditor such access to the Books and Records as may reasonably be required for
the preparation and/or review of the Closing 


                                      -9-
<PAGE>

Statement of Net Assets. All fees and expenses of E&Y relating to the
preparation of the Closing Statement of Net Assets shall be borne equally by
Seller and Buyer.

                          (c)     Review of Closing Statement of Net Assets.
After receipt of the Closing Statement of Net Assets, Buyer shall have thirty
(30) days to review it.  Buyer and its authorized representatives shall have
full access to all Books and Records and appropriate employees of the Seller
and its accountants to the extent required to complete their review of the
Closing Statement of Net Assets including work papers used in preparation
thereof. Unless the Buyer delivers written notice to Seller on or prior to the
30th day after receipt of the Closing Statement of Net Assets specifying in
reasonable detail all disputed items and the basis therefor, the parties shall
be deemed to have accepted and agreed to the Closing Statement of Net Assets.
If Buyer so notifies the Seller of an objection to the Closing Statement of Net
Assets, the parties shall, within thirty (30) days following the date of such
notice (the "Resolution Period") attempt to resolve their differences and any
resolution by them as to any disputed amount shall be final, binding,
conclusive and nonappealable for all purposes under this Agreement.

                          (d)     Resolution.  If at the conclusion of the
Resolution Period the parties have not reached an agreement on the objections,
then all amounts remaining in dispute may, at the election of either party, be
submitted to Price Waterhouse or another large international accounting firm
not otherwise engaged by either party (the "Neutral Auditor").  Each party
agrees to execute, if requested by the Neutral Auditor, a reasonable engagement
letter.  All fees and expenses relating to the work, if any, to be performed by
the Neutral Auditor shall be borne equally by Seller and Buyer, unless the
Neutral Auditor finds one party acted in bad faith in which case that party
pays all.  Except as provided in the preceding sentence, all other costs and
expenses incurred by the parties in connection with resolving any dispute
hereunder before the Neutral Auditor shall be borne by the party incurring such
cost and expense.  The Neutral Auditor shall act as an arbitrator to determine,
based solely on the presentations by Seller and Buyer, and not by independent
review, only those issues still in dispute.  The Neutral Auditor's
determination shall be made within thirty (30) days of its engagement (which
engagement shall be made no later than five (5) business days after the
election by either party to submit the objections to the Neutral Auditor) or as
soon thereafter as possible, shall be set forth in a written statement
delivered to Seller and Buyer and shall be final, binding, conclusive and
nonappealable for all purposes hereunder.  The term "Final Closing Statement of
Net Assets," as hereinafter used, shall mean the definitive Closing Statement
of Net Assets agreed to by Seller and Buyer in accordance with Section 2.7(c)
or the definitive Closing Statement of Net Assets resulting


                                      -10-

from the determination made by the Neutral Auditor in accordance with this
Section 2.7(d) (in addition to those items theretofore agreed to by Seller and
Buyer).

The execution and delivery by Seller of this Agreement, and the consummation of
the transactions contemplated hereby, have been duly authorized by all
requisite corporate action of Seller.  Seller has duly executed and delivered
this Agreement.  This Agreement is a legal, valid and binding obligation of
Seller, enforceable against it in accordance with its terms, except as such

conveyance and similar laws affecting creditor's rights generally and by
general equitable principles.

                 3.2      Corporate Status.

                          (a)     Seller is a corporation duly organized,

                          (b)     Seller is duly qualified or licensed to do
business and is in good standing in each of the jurisdictions in which the
operation of the Business or the character of the properties owned, leased or
operated by it in connection with the Business makes such qualification or

Schedule 3.2(b).

                          (c)     Seller has delivered to Buyer complete and

in a violation of or a default under (with or without the giving of notice or
the lapse of time or both), or result in the acceleration of or give rise to

necessary to operate the Business consistent with past practice.  On the date
hereof and at the Closing, all Intellectual Property Licenses are or will be in

infringed by third parties.  Except as set forth on Schedule 3.16(d), there is

pending or, to the knowledge of Seller, threatened, that challenges the rights

of Business.  Seller has, or on the Closing Date will have, good and marketable
fee simple title to the Owned Real Property indicated on Schedule 3.18(a) as
being owned by it, free and clear of all Liens other than Permitted Liens.
There are no outstanding options or rights of first refusal to purchase the
Owned Real Property, or any


                                      -19-

                                  (ii)     For a period of six months from the
Closing Date (the "Window Period"), Seller shall and hereby irrevocably grants,
effective as of the Closing Date, on a fully-paid, royalty-free basis, the
Buyer the right to use the California Microwave Logo and the California
Microwave Name in connection with the operation of the Business as currently
conducted including, during the Window Period, to (A) use any molds or castings
included in the equipment or machinery included in the Assets despite the
appearance thereon and on the products manufactured therewith of the Name
California Microwave or the California Microwave Logo, (B) market and sell all
such products produced by the Business and (C) use any other assets on hand
included in the Assets, including, without limitation, any catalogs, invoices,
packaging material or stationery, bearing the California Microwave Name or
California Microwave Logo.  Immediately upon the expiration of the Window
Period, Buyer shall cease to use in any manner the Name California Microwave or
the California Microwave Logo incorporating such Name and remove or obliterate
such Name or the California Microwave Logo from any molds, castings, products
or other assets and clearly and prominently mark the new name of the Business
thereon.  At all times following the Closing, Buyer shall indicate that neither
Buyer nor the Business are affiliated with Seller or any of its affiliates.

                          (e)     Substitute Letters of Credit and Bonds.
Buyer shall use commercially reasonable efforts to furnish as of the Closing or
as soon as practicable thereafter, its own letters of credit or performance or
surety bonds in substitution for the letters of credit and bonds referred to in
Schedule 5.2(e)


                                      -30-

attached hereto and agrees to reimburse Seller for any out-of-pocket bank fees
or charges incurred by Seller by reason of any of the same remaining
outstanding from and after 30 days after the Closing Date.

                          (f)     Reimbursement of Certain Severance
Obligations.  Schedule 5.2(f) lists three severance agreements heretofore
entered into between Seller and each of Messrs. Maloney, Strean and Pinto (each
an "Executive"), respectively (each a "Severance Agreement").  If (i) an
Executive becomes employed by Buyer as of the Closing Date as a Transferred
Employee, (ii) there shall occur thereafter a termination by such Executive of
his employment with Buyer for Good Reason (as defined below) within one year
after the Closing Date, and (iii) as a result of the termination of employment
of the type described in clause (ii) above, Seller shall be obligated to make
any cash payment to such Executive pursuant to the provisions of the Severance
Agreement with such Executive, then Buyer shall reimburse Seller for any such
cash payment it so makes to such Executive, such reimbursement to occur
promptly upon receipt by Buyer of evidence of the making of such payment;
provided, however, that the reimbursement obligation of Buyer to Seller under
this Section 5.2(f) with respect to any Executive shall not in any event exceed
the amount that would have been payable to such Executive under his retention
incentive agreement that is listed on Schedule 2.4(a) in the event of an
involuntary termination by Buyer without cause of the employment of such
Executive after the Closing; provided further, however, Buyer shall have no
reimbursement obligation to Seller under this Section 5.2(f) if Buyer otherwise
is obligated to make a payment to the Executive under his retention incentive
agreement pursuant to Section 2.4(a).

                 As used herein, "Good Reason" means the occurrence of any of
the following:  (x) the assignment to the Executive in question of duties
inconsistent with, or a substantial alteration in the nature or status of, such
Executive's responsibilities with respect to the Business at the STS Division
immediately before the Closing; (y) a reduction in the Employee's base salary
or in the benefits that Buyer is required to provide such Executive pursuant to
Section 7.2; or (z) such Executive's relocation to a work site requiring an
increase in one-way commute from such Executive's residence of more than 35
miles.

                      EMPLOYEES AND EMPLOYEE BENEFIT PLANS

                 7.1      Employment of Seller's Employees.  Buyer intends to

Date.  Buyer will provide or establish a cash incentive bonus program(s) based
on the achievement of financial targets to those Transferred Employees who
currently are eligible for cash incentive bonus program(s) of Seller based on
the achievement of financial targets, which cash incentive program(s) of Buyer
shall be comparable in the aggregate to such cash incentive bonus program(s) of
Seller.


                                  ARTICLE VIII
                                  TERMINATION

                 8.1      Termination.  This Agreement may be terminated at any
time prior to the Closing Date:

                          (a)     by the written agreement of Buyer and Seller;

                          (b)     by either Seller or Buyer by written notice

Buyer;

                          (c)     by Buyer by written notice to Seller if (i)

apparent that any of such conditions will not be, fulfilled by 5:00 p.m.
California time on February 15, 1998, unless such failure shall be due to the
failure of Buyer to


                                      -36-
<PAGE>

perform or comply with any of the covenants, agreements or conditions hereof to
be performed or complied with by it prior to the Closing; or

                          (d)     by Seller by written notice to Buyer if (i)
the representations and warranties of Buyer shall not have been true and
correct in all material respects as of the date when made or (ii) if any of the
conditions set forth in Section 6.1 or 6.3 shall not have been, or if it
becomes apparent that any of such conditions will not be, fulfilled by 5:00

the failure of Seller to perform or comply with any of the covenants,
agreements or conditions hereof to be performed or complied with by it prior to
the Closing.

                 8.2      Effect of Termination.  In the event of the

specified in Section 10.2 and except for any liability resulting from such

                 9.1      By Seller.  Subject to the terms and conditions of
this Article IX, Seller covenants and agrees to defend, indemnify and hold
harmless Buyer, its officers, directors, employees, agents, advisers,
representatives and Affiliates (collectively, the "Buyer Indemnitees") from and
against, and pay or reimburse Buyer Indemnitees for, any and all claims,
liabilities, obligations, losses, fines, costs, proceedings, deficiencies or
damages (whether absolute, accrued, conditional or otherwise and whether or not
resulting from third party claims), including out-of-pocket expenses and
reasonable attorneys' fees incurred in the investigation or defense of any of
the same or in asserting any of their respective rights hereunder
(collectively, "Losses"), resulting from or arising out of:

                            (i)   Any misrepresentation or breach of any
warranty of Seller contained in this Agreement; provided that any claim for
indemnification by Buyer under this clause (i) may be made no later than 18
months from and after the Closing Date, excepting only that any claim for
misrepresentation or breach of warranty under Sections 3.6, 3.10(a), 3.18(a),

                                      -37-
<PAGE>

                           (ii)   any failure of Seller to perform any covenant

                          (iii)   any Excluded Liabilities;

Employees except, with respect to Transferred Employees, to the extent assumed
by Buyer pursuant to Article VII; and

                            (v)   any product liability claim with respect to
products manufactured by Seller and sold prior to the Closing.

                 Seller shall not be required to indemnify Buyer Indemnitees
with respect to any claim for indemnification resulting from or arising out of
matters described in clauses (i) and (v) above pursuant to this Section unless
and until the aggregate amount of all claims against Seller exceeds $270,000
and then only to the extent such aggregate amount exceeds $270,000.  Claims
thereafter may be asserted regardless of amount.  Seller's maximum liability to
Buyer Indemnitees under clauses (i) and (v) of this Section shall not exceed
$13,750,000.

                 9.2      By Buyer.  Subject to the terms and condition of this
Article IX, Buyer covenants and agrees to defend, indemnify and hold harmless
Seller and its officers, directors, employees, agents, advisers,
representatives and Affiliates (collectively, the "Seller Indemnitees") from
and against any and all Losses resulting from or arising out of:

                            (i)   any misrepresentation or breach of warranty
of Buyer contained in this Agreement or in any Schedule of Buyer; provided that
any claim for indemnification by Seller under this paragraph (i) may be made no
later than 18 months from and after the Closing Date;

                           (ii)   any failure of Buyer to perform any covenant
or agreement made or contained in the Agreement or fulfill any other obligation
in respect thereof;

                          (iii)   the Assumed Liabilities;

                           (iv)   claims made on or drawings under any of the
letters of credit or performance or surety bonds referred to in Schedule 5.2(e)
attached hereto;


                                      -38-
<PAGE>

                            (v)   the use by Buyer of any Seller tradenames or
trademarks after the Closing Date other than as permitted or contemplated by
Section 5.2(d); and

                           (vi)   the operation of the Business by Buyer or
Buyer's ownership, operation or use of the Assets following the Closing Date
except to the extent that such Loss is the result of any action of Seller prior
to the Closing.

                 Buyer shall not be required to indemnify Seller Indemnitees
with respect to any claim for indemnification resulting from or arising out of
matters described in clause (i) above pursuant to this Section unless and until
the aggregate amount of all claims against Buyer exceeds $270,000 and then only
to the extent such aggregate amount exceeds $270,000.  Buyer's maximum
liability to Seller Indemnitees under clause (i) of this Section shall not
exceed $13,750,000.

                 9.3      Adjustments to Indemnification Payments.  Any payment
made by Seller to Buyer Indemnitees, on the one hand, or by Buyer to Seller
Indemnitees, on the other hand, pursuant to this Article IX in respect of any
claim shall be net of any insurance proceeds realized by and paid to the
Indemnified Party in respect of such claim.  The Indemnified Party shall use
its reasonable efforts to make insurance claims relating to any claim for which
it is seeking indemnification pursuant to this Article IX; provided that the
Indemnified Party shall not be obligated to make such an insurance claim if the
Indemnified Party in its reasonable judgment believes that the cost of pursuing
such an insurance claim together with any corresponding increase in insurance
premiums or other chargebacks to the Indemnified Party, as the case may be,
would exceed the value of the claim for which the Indemnified Party is seeking
indemnification.

                 9.4      Indemnification Procedures.  In the case of any claim
asserted by a third party against a party entitled to indemnification under
this Agreement (the "Indemnified Party"), notice shall be given by the
Indemnified Party to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual
knowledge of any claim as to which indemnity may be sought, and the Indemnified
Party shall permit the Indemnifying Party (at the expense of such Indemnifying
Party) to assume the defense of any third party claim or any litigation with a
third party resulting therefrom, provided that (i) the counsel for the
Indemnifying Party who shall conduct the defense of such claim or litigation 
shall be reasonably satisfactory to the Indemnified Party, (ii) the Indemnified
Party may participate in such defense at such Indemnified Party's expense, and
(iii) the omission by any Indemnified Party to give notice as provided herein
shall not relieve the


                                      -39-
<PAGE>

Indemnifying Party of its indemnification obligation under this Agreement except
and only to the extent that such Indemnifying Party is materially damaged as a
result of such failure to give notice. Except with the prior written consent of
the Indemnified Party, no Indemnifying Party, in the defense of any such claim
or litigation, shall consent to entry of any judgment or enter into any
settlement that provides for injunctive or other nonmonetary relief affecting
the Indemnified Party or that does not include as an unconditional term thereof
the giving by each claimant or plaintiff to such Indemnified Party of a release
from all liability with respect to such claim or litigation. In the event that
the Indemnified Party shall in good faith determine that the conduct of the
defense of any claim subject to indemnification hereunder or any proposed
settlement of any such claim by the Indemnifying Party might be expected to
affect adversely the Indemnified Party's Tax liability or the ability of Buyer
to conduct its business, or that the Indemnified Party may have available to it
one or more defenses or counterclaims that are inconsistent with one or more of
those that may be available to the Indemnifying Party in respect of such claim
or any litigation relating thereto, the Indemnified Party shall have the right
at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the

                          (g)     Assignment.  This Agreement shall not be

                          (h)     No Third Party Beneficiaries.  Except as
provided in Section 8.2 with respect to indemnification of Indemnified Parties
hereunder, nothing in this Agreement shall confer any rights upon any person or
entity other than the parties hereto and their respective heirs, successors and
permitted assigns.

                          (i)     Amendment; Waivers, etc.  No amendment,
modification or discharge of this Agreement, and no waiver hereunder, shall be
valid or binding unless set forth in writing and duly executed by the party
against whom enforcement of the amendment, modification, discharge or waiver is
sought.  Any such waiver shall constitute a waiver only with respect to the
specific matter described in such writing and shall in no way impair the rights
of the party granting such waiver in any other respect or at any other time.
Neither the waiver by any of the parties hereto of a breach of or a default
under any of the provisions of this Agreement, nor the failure by any of the
parties, on one or more occasions, to enforce any of the provisions of this
Agreement or to exercise any right or privilege hereunder, shall be construed
as a waiver of any other breach or default of a similar nature, or as a waiver
of any of such provisions, rights or privileges hereunder.

                 10.6     Arbitration Procedure.

                          (a)     Buyer and Seller agree that the arbitration
procedure set forth below shall be the sole and exclusive method for resolving
and remedying any and all disputes regarding claims for money damages based
upon, arising out of or in any way connected with this Agreement or the
transactions contemplated herein (the "Disputes").  Nothing in this Section
10.6 shall prohibit a party hereto from instituting litigation to enforce any
Final Determination (as defined below).  The parties hereby agree and
acknowledge that, except as otherwise provided in this Section 10.6 or in the
Commercial Arbitration Rules of the American Arbitration Association as in
effect from time to time, the arbitration procedures and any Final
Determination hereunder shall be governed by and shall be enforced pursuant to
the Uniform Arbitration Act as in effect in the State of New York.

                          (b)     In the event that any party asserts that
there exists a Dispute, such party shall deliver a written notice to each other
party involved therein specifying the nature of the asserted Dispute and
requesting a meeting to attempt to resolve the same.  If no such resolution is
reached within 45 days after such delivery of such notice, the party delivering
such notice of Dispute (the "Disputing Person") may, within 75 days after
delivery of such notice, commence arbitration hereunder by delivering to each
other party involved therein a notice of arbitration (a "Notice of
Arbitration") and by filing a copy of such Notice of Arbitration with the New
York City office of the American


                                      -51-
<PAGE>

Arbitration Association.  Such Notice of Arbitration shall specify the matters
as to which arbitration is sought, the nature of any Dispute, the claims of
each party to the arbitration and the amount and nature of damages or other
relief sought to be recovered as a result of any alleged claim and any other
matters required by the Commercial Arbitration Rules of the American
Arbitration Association as in effect from time to time to be included therein.

                          (c)     Buyer and Seller each shall select one
arbitrator expert in the subject matter of the Dispute (the arbitrators so
selected shall be referred to herein as "Buyer's Arbitrator" and "Seller's
Arbitrator," respectively).  In the event that either party fails to select an
arbitrator as set forth herein within 30 days after the delivery of a Notice of
Arbitration, then the matter shall be resolved by the arbitrator selected by
the other party.  Seller's Arbitrator and Buyer's Arbitrator shall select a
third independent, neutral arbitrator expert in the subject matter of the
Dispute, and the three arbitrators so selected shall resolve the Dispute
according to the procedures set forth in this Section 10.6. If Seller's
Arbitrator and Buyer's Arbitrator are unable to agree on a third arbitrator
within 20 days after their selection, Seller's Arbitrator and Buyer's
Arbitrator shall each prepare a list of three independent arbitrators.
Seller's Arbitrator and Buyer's Arbitrator shall each have the opportunity to
designate as objectionable and eliminate one arbitrator from the other
arbitrator's list within ten days after submission thereof, and the third
arbitrator shall then be selected by lot from the arbitrators remaining on the
lists submitted by Seller's Arbitrator and Buyer's Arbitrator.

                          (d)     The arbitrators selected pursuant to Section
10.6(c) shall determine the allocation of the costs and expenses of
arbitration.

                          (e)     The arbitration shall be conducted in New
York City, under the Commercial Arbitration Rules of the American Arbitration
Association as in effect from time to time, except as otherwise set forth
herein or as modified by the agreement of Buyer and Seller.  The arbitrators
shall conduct the arbitration such that a final result, determination, finding,
judgment and/or award (the "Final Determination") is made or rendered as soon
as practicable, but in no event later than 120 days after the delivery of the
Notice of Arbitration nor later than ten days following completion of the
arbitration.  The Final Determination shall be made in writing, shall state the
basis for such determination and shall be agreed upon and signed by the sole
arbitrator or by at least two of the three arbitrators (as the case may be).
The Final Determination shall be final and binding on all parties, and there
shall be no appeal from or reexamination of the Final Determination, except for
fraud, perjury, evident partiality or misconduct by an arbitrator prejudicing
the rights of any party and to correct manifest clerical errors.

<PAGE>

                          (f)     Buyer and Seller may enforce any Final
Determination in any state or federal court having jurisdiction over the
Dispute.  For the purpose of any action or proceeding instituted with respect
to any Final Determination, each party hereto hereby irrevocably submits to the
jurisdiction of such courts, irrevocably consents to the service of process by
registered mail or personal service and hereby irrevocably waives, to the
fullest extent permitted by law, any objection which it may have or hereafter
have as to personal jurisdiction, the laying of the venue of any such action or
jurisdiction, the laying of the venue of any such action or proceeding brought
in any such court and any claim that any such action or proceeding brought in
any court has been brought in an inconvenient form.

                 10.7     Attorneys Fees.  In the event any party hereto
initiates any legal action arising out of or in connection with this Agreement,
the prevailing party shall be entitled to recover from the other party all
reasonable attorneys' fees, expert witness fees and expenses incurred by the
prevailing party in connection therewith.

                 10.8     Liability for Transfer Taxes.  Buyer and Seller shall
each be responsible for and pay in a timely manner 50% of all sales (including,
without limitation, bulk sales), use, value added, documentary, stamp, gross
receipts, registration, transfer, conveyance, excise, recording, license and
other similar Taxes and fees ("Transfer Taxes"), arising out of or in
connection with or attributable to the transactions effected pursuant to this
Agreement.  Each party hereto shall prepare and timely file all Tax Returns
required to be filed in respect of Transfer Taxes (including, without
limitation, all notices required to be given with respect to bulk sales taxes)
that are the primary responsibility of such party under applicable law;
provided, however, that such party's


                                      -53-
<PAGE>

preparation of any such Tax Returns shall be subject to the other party's
approval, which approval shall not be withheld or delayed unreasonably.

                 IN WITNESS WHEREOF, the parties have duly executed this
Agreement as of the date first above written.

reasonable steps to maintain the confidentiality of the same. Notwithstanding
the foregoing, either party may disclose such information (i) by judicial or
administrative process or by other requirements of law, (ii) if the same
hereafter is in the public domain through no fault of such party, or (iii) if
the same is later acquired by such party from another source and the other party
is not aware that such source is under an obligation to another Person to keep
such information confidential.

      ARTICLE VI. INFRINGEMENT.

provision of this Agreement by either party, the other party, may, in addition
to all other remedies, immediately obtain and enforce injunctive relief
prohibiting the breach or compelling specific performance without the

                            STS SUPPLY AGREEMENT

      THIS STS SUPPLY AGREEMENT (this "Agreement") is dated ____________ __,
1998 and is entered into between California Microwave, Inc., a Delaware
corporation ("CMI"), and L-3 Communications Corporation, a Delaware corporation
("L-3").

                                  RECITALS

      A. CMI and L-3 have entered into an asset purchase agreement dated as of
December 19, 1997 (the "Purchase Agreement") with respect to the acquisition by
L-3 from CMI of certain assets of the business of designing, integrating and
installing satellite communications systems in the United States and certain
other countries (such business is the "STS Division").

      B. CMI and L-3 each desire to continue at favored customer prices certain
supply arrangements currently in effect between the STS Division of CMI, on
the one hand, and other subsidiaries and divisions of CMI, on the other hand,
after the date of closing (the "Closing Date") of the purchase by L-3 of the
assets of CMI contemplated by the Purchase Agreement.

      NOW THEREFORE, as a condition to the closing of the transactions
contemplated by the Purchase Agreement, and in consideration of the mutual
covenants, representations and warranties made herein, and of the mutual
benefits to be derived hereby, the parties hereto agree as follows:

      1. Supply of Products by CMI. Upon the terms and subject to the conditions
hereof, for two years from the Closing Date, CMI shall, or shall cause its
subsidiaries (including EF Data Corp. ("EF Data")) to, sell to L-3, and L-3
shall purchase from CMI and/or its subsidiaries the following products and
subassemblies (the "STS Products") needed in operating the STS Division's
business after the Closing Date that CMI or EF Data currently supplies to the
STS Division: satellite communications modems, codecs, transceivers, converters,
Verticom "brick" converter modules (the "Brick Modules"), the ICU-64 Channel
Unit for LYNXX (the "LYNXX"), the PL/5617-1 Modulator card for PROGENY (the
"Card") (the Brick Modules, the LYNXX and the Card are the "Source Products")
and network products. Without limiting the obligation of L-3 to purchase STS
Products under the preceding sentence, the quantities of STS Products to be
purchased by L-3 pursuant to this Section shall be at the sole discretion of L-3
and no minimum quantities of STS Products are required to be purchased
hereunder, Notwithstanding the preceding two sentences, if CMI provides written
notice to L-3 specifying any STS Products subject to this Section that CMI
intends to discontinue making or selling, CMI will be relieved of any obligation
to sell to L-3 any such product as of one year from the date that CMI so
notifies L-3.


                                      -1-
<PAGE>

      2. Provision of Services by L-3. For two years from the Closing Date, CMI
shall exclusively engage L-3 to provide the following services (the "Services")
to CMI for the benefit of CMI's customers that have requested CMI to arrange for
the procurement of satellite communications system engineering and/or satellite
communications systems integration services for commercial (ie, non-U.S.
government) projects or for foreign governmental authorities projects: system
design, integration, installation and/or program management. Without limiting
the obligation of CMI to purchase the Services under the preceding sentence, the
quantities of Services to be purchased by CMI pursuant to this Section shall be
at the sole discretion of CMI and no minimum quantities of Services are required
to be purchased hereunder. Notwithstanding the preceding two sentences, if L-3
provides written notice to CMI specifying any Services subject to this Section
that L-3 intends to discontinue providing, L-3 will be relieved of any
obligation to provide to CMI any such Services as of one year from the date that
L-3 so notifies CMI.

      3. SIVAM Project.

            (a) It is the understanding of the parties that in connection with
the SIVAM project proposals, as currently proposed or as may otherwise be
amended (the "SIVAM Proposals"), L-3 shall have exclusive access to and
communication with Raytheon Corporation ("Raytheon"), whether oral or written,
exclusive of CMI or any of its subsidiaries (including, without limitation,
CMI's Microwave Networks division (the "MN Division"), CMI's Microwave Data
Systems division ("Data Systems") and EF Data, with respect to or in connection
with the SIVAM Project including, without limitation, any proposal, discussion,
marketing, negotiation, pricing, settlement, procurement, arrangement or
understanding with respect to the SIVAM Project.

            (b) From the Closing Date to December 31, 1998 (the "Supply
Period"), CMI shall, and shall cause its subsidiaries (including EF Data) to,
deliver to L-3 the products specified in the SIVAM Proposals (the "SIVAM
Products") in accordance with the quantities, product specifications and time
period proposed by such divisions in the SIVAM Proposals, and L-3 shall
purchase, during such Supply Period, the SIVAM Products from such divisions or
subsidiaries in accordance with the SIVAM Proposals, provided that:

                  (i) CMI accepts the terms and conditions of and performs its
duties under, as subcontractor to L-3, the contract or agreement awarded by
Raytheon to L-3 for the SIVAM Project, including, without limitation, payments
made under a vendor trust arrangement generally required by Raytheon; and

                  (ii) the pricing for each SIVAM Product quoted by CMI
(including EF Data, the MN Division and Data Systems) is competitive with, and
in no event more than 5% above, any proposal made in good faith by a legitimate
party which seeks to sell such SIVAM Product to L-3 and which agrees to perform
the duties and obligations as a subcontractor to L-3 under


                                      -2-
<PAGE>

the SIVAM Project with respect to such Product. In the event that L-3 is
permitted to purchase a SIVAM Product from a party other than CMI or EF Data
pursuant to this clause (ii) because that product has not met the conditions set
forth in this clause (ii), L-3 will remain obligated to purchase from CMI all of
the other SIVAM Products so long as those products meet the conditions in this
clause (ii) and clause (i) above and subject to the other terms and conditions
hereof.

      As used herein, the term "Product" shall mean a STS Product or a SIVAM
Product.

      4. Prices.

            (a) Source Products. CMI shall sell (or cause its subsidiaries to
sell) each Source Product to L-3 at the unit price (the "Unit Price") listed for
such Source Products on Schedule 4(a) attached hereto. The prices set forth in
Schedule 4(a) are not subject to increase during the first six months from the
Closing Date. Thereafter, CMI, or its subsidiaries, may increase such prices,
except that in no event shall (i) the Unit Price of any Source Product be less
favorable than the unit price given to other customer for such Source Product in
like quantities and (ii) any such increase in price increase the gross margin
percentage of CMI or its subsidiaries with respect to such Source Product from
its current gross margin percentage thereon. Upon L-3's written request, CMI
will provide L-3 with reasonable access during normal business hours to the
books and records of CMI and its subsidiaries for the sole purpose of
verifying the gross margin percentages with respect to the Source Products.

            (b) STS Products. CMI shall sell (or cause its subsidiaries to
sell) the STS Products, other than the Source Products, at prices no less
favorable than the prices given to other customers of such products in like
quantities.

            (c) Services. L-3 shall provide the Services to CMI at prices no
less favorable than the prices given to other customers of such Services in like
quantities.

      5. Additional Terms and Conditions.

            (a) CMI Terms and Conditions. Any sale of the STS Products by CMI or
any of its subsidiaries under this Agreement shall be subject to and governed by
the then-current standard terms and conditions (including as to warranty) of
CMI (or its subsidiaries), which terms and conditions shall be no less
favorable that those given to other customers for the same or similar products.

            (b) L-3 Terms and Conditions. Any sale of the Services by L-3 under
this Agreement shall be subject to and governed by the then-current standard
terms and conditions (including as to warranty) of L-3, which terms


                                      -3-
<PAGE>

and conditions shall be no less favorable that those given to other customers
for the same or similar services.

       6. Specifications. CMI shall, or cause its subsidiaries to, manufacture
and deliver the STS Products in accordance with the electrical, mechanical,
physical, environmental and other specifications as in effect as of the Closing
Date, or if the STS Product is a non-standard product, then according to the
specifications agreed to in writing by L-3 and CMI from time to time. In the
event an improvement or a technical change in the specifications of the STS
Products is made by CMI, CMI shall be required to provide the STS Products which
meet such improved or changed specifications; provided, however, that no such
improvement or change in specifications shall be made to LYNXX without the prior
written consent of L-3. CMI shall, or cause its subsidiaries to, manufacture and
deliver the SIVAM Products to L-3 in accordance with the specifications therefor
in the SIVAM Proposals.

       7. Maintenance of Standards. If CMI fails to maintain the quality,
delivery or performance standards currently applicable to the Products, or fails
to achieve standards of quality or performance specified by CMI with respect to
new variations of the standard Products, then L-3 shall have such remedies as
may be provided in the then-current standard terms and conditions of CMI, and,
if CMI fails to cure any such deficiency in any Product within 60 days after
written notice thereof by L-3, L-3 shall no longer be obligated to purchase such
Product pursuant to this Agreement.

       8. Ordering. Each order by L-3 for STS Products (a "Purchase Order") will
specify the STS Products, the quantity, the appropriate specifications
corresponding to such STS Products (if necessary), and the date of delivery,
provided that the number of days from the date of the Purchase Order through the
date of delivery is at least 60 days. Notwithstanding the foregoing, the parties
hereafter may agree in writing to use a blanket purchase agreement with specific
agreed call out schedules in lieu of the foregoing ordering mechanism. Orders by
L-3 for SIVAM Products shall be made in accordance with the SIVAM Proposals.

      9. Delivery.

            (a) All STS Products will be delivered freight paid F.O.B. (CMI's
(or its subsidiary's) plant).

            (b) L-3 reserves the right to inspect the STS Products and to
confirm the quantity of the STS Products within 30 days from the date of
delivery. Any claims for discrepant deliveries shall be reported by L-3 to CMI
in writing within such 30-day period. If L-3 fails to make such a claim within
the time specified, such order will be deemed accepted by L-3. Upon CMI
receiving notice from L-3 of such discrepancy, L-3 will have such remedies as
may be provided in the then-current standard terms and conditions of CMI.


                                      -4-

SIVAM Proposal.

      10. Raw and Packaging Materials. CMI will purchase and supply all raw
materials and packaging materials necessary for the manufacture of the STS
Products. CMI will be responsible for the sampling and testing of all such raw
materials and packaging materials and for ensuring an adequate inventory of such
raw materials and packaging materials to supply the STS Products.

      11. Terms of Sale. With respect to any Products or Services sold
hereunder, the selling party will invoice the other party at the time of
delivery or provision. Each invoice will be itemized in reasonable detail. The
non-selling party will pay to the selling party the amount of such invoice
within 60 days of the date of such invoice.

      12. Confidentiality. Each party will preserve the confidentiality of the
other party's Confidential Information (defined below), will not use same except
in connection with the performance of its obligations hereunder, and will return
same upon request by the other party. This Section will survive expiration or
earlier termination of this Agreement for a period of three years thereafter.
"Confidential Information" means all proprietary information (including but not
limited to formulas, compilations, data, know-how, specifications, techniques,
inventions, devices, projections, drawings and plans, whether of a technical,
operational, financial or other nature) which hereafter is, or in the past has
been, disclosed in writing and marked as confidential by either party (the
"Disclosing Party") to the other party (the "Receiving Party"), and which is of
such a nature that its value would be impaired if disclosed to third parties,
but shall not include any such information that: (i) becomes part of the public
domain through no fault of the Receiving Party; (ii) at the time of receipt is
known to the Receiving Party as shown by its written records; (iii) becomes
known to the Receiving Party from another source and the Receiving Party is not
aware that such source is under an obligation to another Person to keep such
information confidential; or (iv) is required to be disclosed by the Receiving
Party as a result of judicial or administrative process or by other requirements
of law.

      13. Indemnity.

            (a) With respect to any Products or Services sold hereunder, the
selling party agrees to indemnify and hold the other party and its affiliates
and their respective officers, directors, employees and agents, harmless from
and against any damages, liabilities, losses, expenses, (including, without
limitation, reasonable attorneys' fees) and amounts paid in settlement of any
claim, of any kind or nature whatsoever, which may be sustained or suffered as a
result of the infringement or alleged infringement of the copyrights or


                                      -5-
<PAGE>

U.S. patents of third parties or the breach by CMI of its represention in the
fourth sentence of Section 3.16 of the Purchase Agreement, and to defend, at its
expense, any actions, claims or suits against purchasing party based upon such
infringement or alleged infringement. If the use of any products furnished
hereunder is enjoined as a result of such a suit, the selling party at its
option, and at no expense to the other party, shall obtain for the other party
the right to use said products, substitute an equivalent product reasonably
acceptable to selling party and extend this indemnity thereto, or accept the
return of products and reimburse the other party the purchase price thereof,
less a charge for reasonable wear and tear. This indemnity does not extend to
any suit based upon any infringement or alleged infringement of any patent or
copyright to the extent due to the combination of any products furnished by the
selling party and other elements not supplied by or on behalf of the selling
party nor does it extend to any products to the extent such products infringe as
a result of the other party's design or formula.

            (b) The purchasing party agrees to notify the selling party in
writing of any suit. At its request and at its expense the selling party shall
have the right to control the defense of said suit. Except with the prior
written consent of the purchasing party, no selling party, in the defense of any
such claim or litigation, shall consent to entry of any judgment or enter into
any settlement that provides for injunctive or other nonmonetary relief
affecting the purchasing party or that does not include as an unconditional term
thereof the giving by each claimant or plaintiff to such purchasing party of a
release from all liability with respect to such claim or litigation. In the
event that the purchasing party shall in good faith determine that the conduct
of the defense of any claim subject to indemnification hereunder or any proposed
settlement of any such claim by the selling party might be expected to affect
adversely the purchasing party's tax liability or the ability of the purchasing
party to conduct its business, or that the purchasing party may have available
to it one or more defenses or counterclaims that are inconsistent with one or
more of those that may be available to the selling party in respect of such
claim or any litigation relating thereto, the purchasing party shall have the
right at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the
selling party, provided that if the purchasing party does so take over and
assume control, the purchasing party shall not settle such claim or litigation
without the written consent of the selling party, such consent not to be
unreasonably withheld. In the event that the selling party does not accept the
defense of any matter as above provided, the purchasing party shall have the
full right to defend against any such claim or demand and shall be entitled to
settle or agree to pay in full such claim or demand. In any event, the selling
party and the purchasing party shall cooperate in the defense of any claim or
litigation subject to this Section and the records of each shall be available to
the other with respect to such defense.

            (c) The foregoing Sections 13(a) and (b) state the entire liability
of the selling party for patent or copyright infringement. This Section will
survive the expiration or earlier termination of this Agreement.

United States Export Control Administration Regulations, the United States

other party for Products or Services previously delivered or provided hereunder,

Services) shall be excused to the extent that such failure is attributable to
any cause beyond the reasonable control of the defaulting party, including,
without limitation, acts of God, fires, earthquakes, wars, sabotage, accidents,
embargo, riots, labor disputes, actions of any government or


                                      -7-

governmental agency or failure of same to act where action is required, and the

party shall give notice to the other party without delay of the occurrence of
the event or circumstances in question.

construed to constitute either as a partner, agent or employee of the other.
Neither party is authorized to act for or bind the other except as specifically
provided herein.

            (b) The failure of a party at any time to require performance by the
other party of any provision hereof shall in no way affect the right of the
party thereafter to enforce same against the other party, nor shall waiver by
either party of the breach of any provision hereof be taken or held to be a
waiver of any succeeding breach of such provision or as a waiver of the

            (c) If any term or provision of this Agreement is invalid, illegal
or incapable of being enforced by any rule of law or public policy, such
provisions will be narrowed (or deleted, if necessary) to the minimum extent

except by a writing signed by both of the parties.

            (f) This Agreement may be executed with counterpart signature pages

            (g) The agreements that comprise this Agreement, the Purchase

                                  SCHEDULE 3.5

                                   LIABILITIES

1. In connection with a sales agreement entered into between Seller and a
classified U.S. government entity on September 8, 1988, Seller received a
letter dated April 25, 1997 from the federal government making conflicting
claims regarding an overpayment. The letter claims an overpayment of
approximately $39,000 and an overpayment of $1,026,993. Seller believes that no
overpayment was made and is currently presenting accounting records to the
federal government to substantiate its position.

2. Patrick & Co. claimed, by letter dated September 18, 1997, that Seller pay
it a commission of 2% (equalling approximately $290,000) on the total value of
the Contract between the Government of the Islamic Republic of Pakistan and
California Microwave-Satellite Transmission Systems dated March 17, 1996,
concerning the supply of satellite earth station equipment. Patrick & Co.
asserts that it arranged for the customer's financing of the transaction and in
return is entitled to a commission promised by Seller. Seller believes that it
did not promise a commission and that Patrick & Co. did not successfully
arrange the customer financing.

3. Nu Vision Manufacturing claimed $143,702.37 against Seller by letter dated
December 31, 1996. This claim arose with respect to Blanket Purchase Order No.
138326, dated January 11, 1995. Seller believes that the claim has no merit. In
June 1997, Nu Vision lowered its demand to approximately $70,000, and Seller,
at that time, offered to settle for $10,000 in order to clear the matter.
Seller has not received any communications from Nu Vision Manufacturing or its
counsel since the June, 1997 meeting.

4. In connection with Job Number 6367 in the Sudan, all work has been
terminated effective December 3, 1997, due to an Executive Order of President
Clinton imposing an embargo against Sudan. Seller has withdrawn all of its
personel in the Sudan. Consequently, there is no further activity under the
contract. $1,000,000 with respect to this contract was written off in October,
1997.

5. In connection with Job Number 6495 with Romsat, Romsat still has not
obtained the necessary financing to purchase the remaining equipment under the
relevant contract. If Romsat does not obtain such financing, Seller may have to
write off $175,000 of accounts receivable and dispose of the remaining $1.2
million in inventory earmarked for the Romsat project.

                                      TAXES

1. Income tax returns have not yet been filed in Malaysia for fiscal years 1996
and 1997 and in Singapore for fiscal years 1997. Seller obtained an extension
of the due date for both filings in Malaysia to September 1997. Seller is
working with its accountants, Ernst & Young, to bring the filings up to date.
Seller does not believe that it owes any income tax in either jurisdiction.

                                  SCHEDULE 3.7

                               ABSENCE OF CHANGES

1. Schedule 3.7

      In October, 1997, Seller decreased the opening backlog for fiscal year
1998 by $3,617,440. Most of the reduction in backlog is attributable to the
following three accounts:

      The orders with respect to Alphastar (Job 1026) and TeeCom (Alphastar's
parent company) (Job 6438) booked on March 21, 1997 and April 11, 1997,
respectively, will be reduced by approximately $2.4 million and $341,000,
respectively, due to the declaration of bankruptcy by those companies.

      The order with respect to Onatel (Job 6280) booked on May 12, 1993 will
be reduced by approximately $240,000. The customer has stated it does not need
the product and Seller is unwilling to risk its personnel in a country engaged
in a civil war.

                           ATTACHMENT TO SCHEDULE 3.15

                             WARRANTIES AND REPAIRS

      (A) Terms of Warranty - California Microwave, Inc. - Satellite
Transmission Systems Division ("CM-STS") warrants that the Equipment furnished
will be free from defects in design, material and workmanship and will conform
to the contract specifications for a period of one (1) year commencing from the
date the Equipment is accepted under a Provisional or Final Acceptance. If not
accepted, the Warranty Period shall commence thirty (30) days after delivery.
This warranty shall survive acceptance and payment.

      At any time within the Warranty Period, CM-STS shall, at its facilities
in Hauppauge, New York, at its option and at its own expense, correct or
replace, within 60 days (if materials are available within a reasonable time),
any part of the Work which is defective in design, materials, or workmanship,
provided Buyer gives CM-STS prompt written notice of such defect and pays all
costs of shipment to CM-STS facility. Shipments by CM-STS of repaired or
replacement equipment to Buyer will be F.O.B. destination, freight prepaid. The
foregoing shall not apply to, and CM-STS shall have no obligation in respect
of, (i) defects in goods caused by improper operation, maintenance or
modification by Buyer or (ii) goods which have been subject to any unauthorized
repair. In this event, Buyer will be charged CM-STS' standard labor rates and
material costs. Any applicable import taxes or duties will be the
responsibility of Buyer.

      Should the defective equipment be a fixed part of the earth station,
field warranty service may be necessary. In this case, unless otherwise agreed
upon, CM-STS will begin onsite repairs within five (5) days of receipt of
notice of defective equipment and make every effort to begin repairs within
twenty-four (24) hours of arrival and inspection, pending availability of
vendor material. Buyer shall reimburse CM-STS for all per diem and travel
expenses associated with field warranty service. CM-STS will bear the costs of
materials and labor during the on-site repairs, unless the failure is caused by
Buyer. In this event, Buyer will be charged CM-STS' standard field man/day
rates and material costs.

      THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER WARRANTIES,
EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE, AND OF ANY
OTHER OBLIGATIONS OR LIABILITY ON CM-STS' PART. UNDER NO CIRCUMSTANCES WILL
CM-STS BE LIABLE FOR ANY LOSS, DAMAGE, EXPENSE OR CONSEQUENTIAL DAMAGES ARISING
IN CONNECTION WITH USE, OR INABILITY TO USE, THE EQUIPMENT, SERVICES OR
DOCUMENTATION.

      The Warranty Period for a11 work which is repaired or replaced under this
Warranty shall extend until the later of the expiration of the Warranty Period,
or ninety (90) days following the completion of the repair.

      (B) Return Procedures - CM-STS products are warranted against defects in
materials and workmanship in accordance with the terms of this Warranty. CM-STS
will, at its option, repair or replace products which prove to be defective
during the warranty period, provided they are returned to CM-STS, and provided
that the preventative maintenance procedures are followed. Repairs necessitated
by misuse are not covered by this warranty. Before any product is returned for
repair and/or adjustment, authorization from CM-STS is required. Instructions
as to how and where the product should be shipped may be obtained from CM-STS
Customer Service Department (516) 272-5600.

The following information, as a minimum, is required:

      1)    Complete name and address of customer location returning material.
      2)    Name, position, and telephone number of individual returning
            equipment.
      3)    Name and telephone number of individual to contact in case of
            questions regarding material.
      4)    "Ship to" address for return of repaired material.
      5)    Whether or not equipment is within warranty.
      6)    Description, part number and serial number of failed unit. When
            reporting failure of HPA components, the EPA serial number is
            required.

      CM-STS Customer Service Desk will advise customer of a Return
Authorization (RMA) number which should be prominently displayed on the outside
of the container adjacent to address label. (Absence of this number may delay
acceptance or repair.) Products returned to CM-STS for repair must be sent
prepaid. CM-STS reserves the right to reject any warranty claim on any item
that has been tampered with or altered in any way. Returned products should be
carefully packaged in the original container or an equivalent, and unless
otherwise indicated, shipped to:

      When any product is returned for examination and inspection, or for any
other reason, the customer and its shipping agency is responsible for all
damage resulting from improper packing, mishandling and loss in transit.

      Repairs or replacements required for non-warranty equipment will not be
initiated without prior customer approval and issuance of purchase order to
cover this effort.

      This warranty is valid only for CM-STS originally supplied equipment. For
"In Warranty" and "Out of Warranty" equipment, CM-STS assumes no responsibility
whatsoever for operation, maladjustment or failure of equipment which results
from any repair or replacement supplied by third parties without prior approval
from CM-STS.

      By returning a product, the owner grants CM-STS permission to open and/or
disassemble the product as required for evaluation. In all cases, CM-STS has
sole responsibility for determining the cause and nature of failure, and the
CM-STS determination shall be final.

      If it is found that a CM-STS product has been returned without cause and
is still serviceable, the customer will be notified, the product returned to
the customer and a charge for test and evaluation will be levied.

      No customer shall initiate a warranty repair or warranty field service
visit with any CM-STS vendor without prior approval from CM-STS Customer
Service Desk.

      Unnecessary expense and loss of time can often be avoided by customer
adherence to the above procedures.

      CM-STS request that our international customers advise Customer Service
by FAX of equipment being returned for repair. In turn, Customer Service will
FAX the RMA number and any special instructions to the customer. Upon shipment,
please provide the following information:

      1)    The airline carrier the equipment was shipped on.
      2)    The date of shipment.
      3)    The flight number and airway bill number.

The CM-STS FAX number is (516) 272-5500.

      All customs documents should indicate that the equipment is being
returned for repair. All customs duties, taxes, levies and other official costs
paid by CM-STS related to the equipment clearing process will be invoiced back
to the customer. Please enclose a copy of the export form with the equipment.
This will ensure that the documentation field by CM-STS for the return shipment
will carry the same information. Customer Service will FAX shipment information
to the customer when the repaired equipment is returned.

      (C) Out of Warranty Repairs - With respect to repairs to equipment
purchased by Buyer after the expiration of the Warranty Period specified above,
CM-STS agrees to provide repair service at Buyer's expense on all equipment
ordered hereunder. Equipment to be repaired under this section shall be
returned by Buyer to CM-STS' facility in Hauppauge, New York (freight prepaid).
Unless otherwise agreed upon, CM-STS will ship the repaired unit which shall
meet the unit's established specifications within thirty (30) days (if
materials are available within a reasonable time) after receipt of the
defective unit. Repaired units will be warranted for ninety (90) days from due
date of shipment.

      If equipment returned for repair is determined to be beyond repair,
CM-STS will so notify Buyer and, if agreed to by Buyer, ship a replacement unit
within a reasonable time of such agreement. The Buyer agrees to pay for such
replacement unit, and it shall be warranted for one (1) year from date of
shipment. If requested by the Buyer, CM-STS will take the necessary steps to
dispose of unrepairable equipment.

      Transportation costs of equipment for repair will be borne by Buyer and
units shall be adequately packed so as to prevent shipping and transportation
damage. All transportation costs associated with the return of repaired and
replacement equipment will be borne by the Buyer. CM-STS will provide support
and repair service for the equipment supplied over the design life of the
equipment as long as such repair service remains available from the applicable
equipment vendor.

estimates to complete ("ETC's") determined on a basis consistent with the method
used for the determination of the September Balance Sheet, and will, at the

preparation of the Closing Statement of Net Assets. Buyer shall be responsible

Buyer shall pay to the Seller in aggregate for any such fiscal year an amount in
cash (subject to Section II.4(c)) equal to the product of (i) $3,000,000 for
1998, $3,300,000 for 1999 and $3,630,000 for 2000 and (ii) a percentage (the

$8,800,000 for 1998, $10,300,000 for 1999 and $12,300,000 for 2000, respectively

No Additional Consideration will be due to the Seller under this Section II.4 in
respect of any fiscal year if the Percentage for that fiscal year shall be less
than 60%. "EBIT" means for any fiscal year operating income of the Acquired
Company before interest and income taxes; provided that for purposes of
calculating EBIT there shall be eliminated (i) the effect of any purchase
accounting adjustments (including any increase in depreciation or amortization

the Acquired Assets for accounting purposes) in connection with the acquisition
of the Company, (ii) all costs and expenses paid in connection with financing
and refinancing the purchase of the Company, (iii) all operating income, if any,
attributable to the SWEATS contract, (iv) all gains (or losses) from
extraordinary items and investments, (v) the cumulative effect of changes in
accounting principles and (vi) the effect (whether revenue or expense) as a
result of any allocation by Buyer of any Buyer-incurred general and
administration expenses or management fees (but only to the extent such
allocation of expenses or fees exceeds amounts which would be an expense of the
operation of the Acquired Company on a stand-alone basis consistent with the
Company's method of operation prior to February 10, 1998). In the event of the
disposition or discontinuation of any of the Acquired Company's current
businesses or operations or the addition of any business or operation to the
Acquired Company, the target EBIT amount referred to above shall be adjusted
appropriately (determined in good faith by the Buyer, in consultation with the
Seller) to reflect such disposition, discontinuation or addition, for purposes
of calculating the Percentage.

      (b) For each of the 1998, 1999 and 2000 fiscal years, Buyer shall, no
later than 45 days following the availability of financial statements for such
period, prepare and deliver to Seller a report (the "EBIT Report") reflecting in
reasonable detail Buyer's calculation of EBIT for the applicable fiscal year
(including any adjustments to Buyer's financial statements made in connection
with such calculation), together with a copy of the financial statements from
which such calculation is derived. EBIT will be calculated in accordance with
GAAP applied on a basis consistent with the Financial Statements (as defined in
Section II.6) and with changes to EAC's and ETC's determined on a basis
consistent with the methods used in the Financial Statements.

      (c) Any payment of Additional Consideration with respect to any fiscal
year shall be payable to the Seller within 30 days after the date on which the
calculation of EBIT for such fiscal year shall have been finally determined
pursuant to this Section II.4 and Section II.5; provided that no such payment of
Additional Consideration (except portions thereof as to which Early Cash Payment
Elections (as defined in Section II.4(e)) have been received by Buyer in
accordance with Section II.4(e)) with respect to any fiscal year shall be
payable by Buyer pursuant to this Section II.4 prior to the earlier of (i) the
date 60 days following the completion of the initial sale to the public pursuant
to an effective registration statement (other than a registration statement on
Form S-4 or Form S-8 or any similar or successor form) (the "Initial Public
Offering") filed under the Securities Act of 1933, as amended (the "Securities
Act"), of shares of the Class A Common Stock, par value $.0l per share of L-3
Communications Holdings Inc. ("Holdings") (or such other class of common stock
of Holdings issued to the holders of such Class A Common Stock in connection
with a reclassification thereof) ("Class A Common Stock") and (ii) September 30,
2001. Seller shall not be permitted to elect to receive shares in lieu of
Additional Consideration for any fiscal year in an amount less than $250,000
unless the Seller is electing to receive shares for all of such Additional
Consideration for such fiscal year. Each cash payment pursuant to this Section
II.4 shall be made by wire transfer of immediately


                                       -9-
<PAGE>

available funds to the account designated by the Seller in a written notice to
Buyer given at least 5 Business Days prior to the date of payment.

      (d) Prior to the date of any payment of Additional Consideration pursuant
to Section II.4(b) (other than payments pursuant to Early Cash Payment
Elections), Buyer shall offer the Seller the opportunity to elect to receive, in
lieu of such payment, any Additional Consideration in the form of shares of
Freely Tradable (as defined below) Class A Common Stock. Such offer of such
shares shall be made in a transaction meeting the requirements of the Securities
Act (and any applicable state securities laws). The number of shares of Class A
Common Stock to be delivered if the Seller elects to receive such shares
pursuant to such offer shall be determined by dividing (i) the amount of such
payment of Additional Consideration by (ii) $20 to the extent such Additional
Consideration relates to fiscal 1998, $22 to the extent such Additional
Consideration relates to fiscal 1999 and $24.20 to the extent such Additional
Consideration relates to fiscal 2000. In the event of any change in the
outstanding Class A Common Stock by reason of stock split, stock combination,
reclassification or similar event, the number of shares to be delivered pursuant
to the preceding sentence shall be adjusted appropriately (e.g., if the
outstanding shares of Class A Common Stock are split on a two-for-one basis, the
$20, $22 and $24.20 amounts referred to in clause (ii) would be adjusted to be
$10, $11 and $12.10, respectively). In the event that the Initial Public
Offering is not completed by August 1, 2001, no offer to elect to receive shares
of Class A Common Stock shall be made pursuant to this Section II.4(d). If the
Seller elects to receive shares pursuant to this Section II.4(d) such shares
will be delivered by registered mail to the address designated by the Seller in
a written notice to Buyer given at least five (5) Business Days prior to the
date of delivery. No fractional shares of Class A Common Stock will be issuable
pursuant to this Section II.4. In lieu thereof, any person who would otherwise
be entitled to a fractional share pursuant to the provisions hereof shall
receive an amount in cash equal to the amount of Additional Consideration which
would have been payable in cash with respect to such fraction. For purposes of
this Section II.4, "Freely Tradable" shall mean Class A Common Stock which (a)
may be sold (without legal restriction) to any member of the public, including a
sale by or through a securities exchange and/or broker-dealer, without the
necessity of (I) obtaining an opinion of counsel, obtaining permission or

respect to the Closing Statement of Net Assets, the Auditor to the extent
required to complete their review of the Closing Statement of Net Assets or the
EBIT Report, as applicable, including Auditor work papers used in preparation or
the Closing Statement of Net Assets. Unless the Buyer delivers written notice to
the Seller, or the Seller delivers written notice to Buyer, on or prior to, the
30th day after receipt of the Closing Statement of Net Assets or the EBIT Report
specifying in reasonable detail all disputed items and the basis therefor, the
parties shall be deemed to have accepted and agreed to the Closing Statement of
Net Assets or the EBIT Report. The parties shall, within thirty (30) days
following the date of such notice (the "Resolution Period"), attempt to resolve
their differences and any resolution by them as to any

<PAGE>

disputed amount shall be final, binding, conclusive and nonappealable for all
purposes under this Agreement.

      (b) Resolution. If at the conclusion of the Resolution Period the parties
have not reached an agreement on the objections, then all amounts remaining in
dispute may, at the election of either party, be submitted to Price Waterhouse
or another large international accounting firm not otherwise engaged by either
party (the "Neutral Auditor"). Each party agrees to execute if requested by the
Neutral Auditor, a reasonable engagement letter. All fees and expenses relating
to the work, if any, to be performed by the Neutral Auditor shall be borne
equally by the Seller and Buyer, unless the Neutral Auditor finds one party
acted in bad faith in which case that party pays all such fees and expenses.
Except as provided in the preceding sentence, all other costs and expenses
incurred by the parties in connection with resolving any dispute hereunder
before the Neutral Auditor shall be borne by the party incurring such cost and
expense. The Neutral Auditor shall act as an arbitrator to determine, based
solely on the presentations by the Seller and Buyer, and not by independent
review, only those issues still in dispute. The Neutral Auditor's determination
shall be made within thirty (30) days of its engagement (which engagement shall
be made no later than five (5) business days after an election by either party
to submit the objections to the Neutral Auditor) or as soon thereafter as
possible, shall be set forth in a written statement delivered to the Seller and
Buyer and shall be final, binding, conclusive and nonappealable for all purposes
hereunder. The term "Final Closing Statement of Net Assets" shall mean the
definitive Closing Statement of Net Assets agreed to in accordance with Section
II.5(a) or the definitive Closing Statement of Net Assets resulting from the
determination made by the Neutral Auditor in accordance with this Section
II.5(b).

                                   ARTICLE VI

                   COVENANTS REGARDING POST CLOSING ACTIVITIES

      VI.1 Employee Matters.

      (a) Immediately following the Closing on the Closing Date, Buyer shall
offer employment at will in a similar position to each employee of the Business
who on the Closing Date is employed by the Acquired Company or on an approved
leave of absence (the "Employees") at a rate of base compensation and salary
equal to not less than one hundred percent (100%) of their base compensation and
salary immediately prior to the Closing Date; provided, however, that nothing
herein shall interfere with or otherwise impair any right of Buyer to terminate
the employment of any employee at any time. Buyer shall assume the
responsibility for all obligations and liabilities arising out of or in any way
connected with its employment of the Employees or the termination thereof,
including, without limitation, any and all claims for wrongful discharge,
discrimination or other violations of law or for payment under any employee
benefit plans for claims incurred after the Closing on the Closing Date. Buyer
shall also offer to Employees participation in benefit programs in accordance
with Buyer's employee benefit plans and other fringe benefits which programs
shall be, at a minimum, substantially comparable, in the aggregate, to the
Company Plans (excluding for these purposes any Company Plans providing equity
awards or equity based awards) and shall be eligible to participate in said
employee benefit plans and other fringe benefits of Buyer immediately and on the
same basis as such plans and benefits are offered to new employees of Buyer;
provided, however, that payment of any deductibles under the Company Plans by
such Employees will be credited under Buyer's plans during 1998; provided,
further, that Buyer may change, amend or terminate any such Company Plans at any
time following the Closing Date. In addition, Buyer agrees that any preexisting
condition clause in any of the Acquired Company's health or disability insurance
coverage shall not be applicable to the Employees to the extent allowable.

      (b) Buyer shall assume and be responsible for all sums then due any
Employee who accepts Buyer's offer of employment, which sums shall include,
without limitation, salary, wages, overtime, bonuses, accrued and unused
vacation time and any other payments due pursuant to any agreements between the
Acquired Company and such Employee payable after the Closing Date or as required
by applicable law. All Employees who accept Buyer's offer of employment shall
receive credit for years of service with or as granted by the Acquired Company.

      (c) Any former employee of the Acquired Company (or their dependents) who
becomes eligible for health continuation coverage under the Acquired Company's
major medical plan by virtue of his or her failure to accept Buyer's offer of
employment being tantamount to a qualifying event, for the entitlement to such
coverage, shall have available health continuation coverage satisfying the
requirements of Section 4870 B of the Code and Section 601 through 608 of ERISA
after the Closing through health benefit plans maintained by Buyer or its
affiliates.

      (d) Buyer covenants and agrees that it will assume and be responsible for
any obligations after the Closing Date to Employees who are on workers'
compensation or a similar leave of absence from the Acquired Company on the
Closing Date to the extent such obligations


                                      -29-
<PAGE>

are (i) pursuant to fully insured Company Plans, or (ii) fully accrued on the
Closing Statement of Net Assets.

      VI.2 Seller's Indemnification.

      (a) Seller's Indemnification. Subject to the limitation of Section
VI.2(c), Seller shall indemnify, defend and hold Buyer and its affiliates (and
their respective officers, directors, employees and agents), harmless from any
liability, damages, deficiency, loss, cost or expense (including but not limited
to reasonable attorney's fees and any expenses of investigation in connection
with any claim hereunder) actually incurred or paid by Buyer and its affiliates
(or their respective officers, directors, employees and agents), arising out of
or resulting from (i) the inaccuracy of any representation or the breach of any
warranty made in this Agreement by Seller to Buyer; (ii) any failure of Seller
to perform or comply with any of its covenants and agreements set forth in this
Agreement; (iii) any Liability of the Seller or any of its affiliates or the
Company or any of its affiliates other than Assumed Liabilities; or (iv) any
Government Bid, Government Contract or Government Disclosure; provided, however,
that Seller shall only indemnify Buyer and its affiliates for the first
$10,000,000 of claims related to any Government Bid, Government Contract or
Government Disclosure. Notwithstanding anything to the contrary contained
herein, the Buyer shall be permitted to offset any amounts which would otherwise
become payable to the Seller under Section 11.4 against amounts owing by the
Seller under this Section VI.2(iv); provided that such right of offset shall
only be exercisable with respect to Additional Consideration if notice of the
exercise of such right is delivered to the Seller by the Buyer prior to the date
on which the calculation of EBIT with respect to such Additional Consideration
shall have been finally determined and agreed to pursuant to Section II.5.

      (b) Tax Indemnification. Seller shall indemnify and hold harmless the
Buyer and its affiliates (and their respective officers, directors, employees
and agents) from and against any and all Taxes for or in respect of each of the
following (excluding, in all cases, Taxes included within the definition of
Assumed Liabilities):

            (i) any and all Taxes with respect to any taxable period or a
      portion thereof, of the Company (or any predecessor) ending on or before
      the close of business on the date three Business Day's prior to the
      Closing Date;

            (ii) with respect to any and all Taxes of any member of a
      consolidated, combined or unitary group of which the Company (or any
      predecessor) is or was a member on or prior to the close of business on
      the date three Business Days prior to the Closing Date by reason of the
      liability of the Company pursuant to Treasury Regulation Section
      1.1502-6(a) (or any analogous or similar state, local or foreign law or
      regulation), as a transferee or successor, by contract, or otherwise;

            (iii) any Taxes arising out of a breach of the representations and
      warranties contained in Section III.15; and

            (iv) any payments required to be made after the Closing Date under
      any Tax sharing, Tax indemnity, Tax allocation or similar contracts
      (whether or not written), to


                                      -30-
<PAGE>

      which the Company or any predecessor was obligated, or was a party, on or
      prior to the close of business on the date three Business Days prior to
      the Closing Date.

      (c) Notification; Control of Proceedings. Buyer shall promptly give to the
Seller written notice if it becomes aware of any liability, loss, damage, claim,
cost and expense with respect to which indemnity may be asserted; provided that
the failure to give prompt notice will not release the Seller from liability
hereunder, except to the extent they are actually prejudiced thereby. If any
claim is made by a third person or an action or proceeding commenced for which
Buyer shall seek indemnity from Seller, Buyer shall give to the Seller
reasonable written notice of the claim and request Seller to defend the same.
Seller shall have the right to defend against such liability at their expense,
and shall give written notice to Buyer of the commencement of such defense with
reasonable promptness after the giving of the written notice of the claim by
Buyer. Buyer shall be entitled to participate with Seller in such defense, but
shall not be entitled in any way to release, waive, settle, modify or pay such
claim without the written consent of the Seller, if Seller have assumed such
defense. In the event Seller does not assume the defense of the matter as
provided above, or does not notify Buyer of its election to defend such a matter
within 30 days, Buyer shall have the full right to defend against such liability
in such manner as it may deem appropriate. In the event Seller shall assume the
defense, Buyer shall cooperate in the defense of such action, and the records of
each shall be available to the other with respect to such defense, provided,
however, that the Seller shall not, in the defense of any such action, consent
to the entry of any judgment or enter into any settlement where such entry of
judgment or settlement does not include a provision releasing the Buyer from all
liability with respect to such action or that provides for a remedy other than
the payment of money damages, except with the written consent of Buyer, such
consent not to be unreasonably withheld or delayed.

      (d) Limitation on Indemnification. Notwithstanding the provisions of
Sections VI.2(a) (except with respect to (A) clauses (ii), (iii) and (iv) of
Section VI.2(a) and (B) Taxes as provided under Section VI.2(b)), (i) Seller
shall not be liable to Buyer on account of any breach of any warranty or
representation by Seller in this Agreement until the aggregate amount of all
claims against Seller for which indemnification would have been available
hereunder but for the application of the limitation set forth in this clause (i)
for all breaches exceeds one percent (1%) of the Cash Purchase Price and then
only for the amount by which such aggregate cumulative liability is in excess of
one percent (1%) of the Cash Purchase Price; and (ii) in no event shall Seller's
obligations to Buyer under Section VI.2(a)(i) exceed, in the aggregate,
$5,000,000.

      (e) Survival. The indemnification obligations of Seller under this Section
VI.2 (except with respect to indemnification pursuant to Section VI.2(a)(ii),
(iii) and (iv)) shall terminate on June 30, 1999 as to any claim not asserted
prior to such date, except that the indemnification obligations of Seller for
(x) a breach of Sections III.1, III.2, III.3, III.5 and III.15 and (y) for Taxes
under Section VI.2(b) shall not terminate until the expiration of the sixty-day
period after the expiration of the applicable statute of limitations as to any
claim not asserted prior to such date and that the indemnification obligations
of Seller for a breach of Sections III.4, III.11 and III.16 shall terminate
three (3) years after the date hereof as to any claim not asserted prior to such
date. The indemnification obligations of Seller (I) under Section VI.2(a)(ii)
shall terminate ten (10) years after the date hereof and (II) under Section
VI.2(a)(iv) shall terminate on June 30, 2000, in each case as to any claim not
asserted prior to such date.


                                      -31-
<PAGE>

      (f) Indemnification Provisions for Benefit of Seller.

            (i) In the event Buyer breaches (or in the event any third party
      alleges facts that, if true, would mean Buyer has breached) any of its
      representations, warranties, and covenants contained in this Agreement or
      in any of the Transaction Documents, then the Buyer agrees to indemnify
      Seller and its affiliates (and their respective officers, directors,
      employees and agents) from and against the entirety of any Losses (up to
      but not in excess of the Cash Purchase Price) Seller or its affiliates
      (and their respective officers, directors, employees and agents) may
      suffer through and after the date of the claim for indemnification
      (including any Losses Seller or its affiliates (and their respective
      officers, directors, employees and agents) may suffer after the end of any
      applicable survival period) resulting from, arising out of, or caused by
      the breach (or the alleged breach).

            (ii) Notwithstanding anything to the contrary herein contained, (i)
      Buyer will indemnify, defend and hold harmless Seller and its affiliates
      (and their respective officers, directors, employees and agents) from and
      against any Losses as a result of claims based on or arising from any
      Assumed Liabilities or the operation of the Business after the Closing
      Date and (ii) such indemnification shall not be limited in time or amount
      or subject to any deductible or cap.

            (iii) Seller or its affiliates shall with reasonable promptness give
      to the Buyer written notice if it becomes aware of any Losses with respect
      to which indemnity may be asserted; provided that the failure to give
      prompt notice will not release the Buyer from liability thereunder, except
      to the extent they are actually prejudiced thereby. If any claim is made
      by a third person or an action or proceeding commenced for which Seller or
      other indemnified parties shall seek indemnity from Buyer, Seller or its
      affiliates shall give to Buyer reasonable written notice of the claim and
      request Buyer to defend the same. Buyer shall have the right to defend
      against such liability at their expense, and shall give written notice to
      Seller of the commencement of such defense with reasonable promptness
      after the giving of the written notice of the claim by Seller or its
      affiliates. Seller or other indemnified parties shall be entitled to
      participate with Buyer in such defense, but shall not be entitled in any
      way to release, waive, settle, modify or pay such claim without the
      written consent of the Buyer, if Buyer has assumed such defense. In the
      event Buyer does not assume the defense of the matter as provided above,
      or does not notify Seller of their election to defend such a matter within
      30 days, Seller or other indemnified parties shall have the full right to
      defend against such liability in such manner as it or they may deem
      appropriate. In the event Buyer shall assume the defense, Seller or other
      indemnified parties shall cooperate in the defense of such action, and the
      records of each shall be available to the other with respect to such
      defense, provided, however, that the Buyer shall not, in the defense of
      any such action, consent to the entry of any judgment or enter into any
      settlement where such entry of judgment or settlement does not include a
      provision releasing the Seller or other indemnified parties from all
      liability with respect to such action or that provides for a remedy other
      than the payment of money damages, except with the written consent of
      Seller or other indemnified parties.

            (iv) The indemnification obligations of Buyer under this Section
      VI.2(f) shall not terminate until the expiration of the applicable statute
      of limitations; provided, however,


                                      -32-
<PAGE>

      that the indemnification obligations of Buyer related to any failure of
      Seller to perform or comply with any of its covenants and agreements set
      forth in this Agreement shall terminate ten years from the date hereof as
      to any claim not asserted prior to such date.

      VI.3 Contracts Requiring Consent to Assignment. Notwithstanding anything
in this Agreement, neither this Agreement nor any document or instrument
delivered pursuant hereto shall constitute an assignment of any claim, contract,
agreement, license, lease, commitment, sales order or purchase order or any
claim or right or any benefit arising thereunder or resulting therefrom if an
attempted assignment thereof without the consent of any other Person would
constitute a breach thereof or in any way adversely affect the rights to be
assigned. Until such consent is obtained, or if an attempted assignment
thereunder would be ineffective or would affect the rights of Seller or any
affiliate thereunder so that the Buyer would not in fact receive all such
rights, Seller and the Buyer will cooperate with each other (and, to the extent
required, Seller shall cause its affiliates to cooperate with the Buyer) to
provide for the Buyer the benefits of, and to permit the Buyer to assume all
liabilities under, any such claim, contract, agreement, license, lease,
commitment, sales order or purchase order, including enforcement at the request
and expense of the Buyer for the benefit of the Buyer of any and all rights of
Seller or any affiliate against a third party thereto arising out of the breach
or cancellation thereof by such third party; and any transfer or assignment to
the Buyer by Seller or any affiliate of any property or property rights or any
contract or agreement which shall require the consent or approval of any third
party shall be made subject to such consent or approval being obtained. The
parties shall each use their best efforts to obtain any required consent to
assignment.

      VI.4 Company Plans. From and after the Closing, Buyer agrees to assume
Seller's obligations under and become the plan sponsor of each of the Company
Plans in effect immediately prior to the Closing Date and Buyer shall be
entitled to all rights, obligations and duties of Seller under such Company
Plans and Seller shall cause any assets, set-aside or otherwise, pertaining to
the Company Plans to be transferred to Buyer; such assets shall include, but not
be limited to, qualified trusts, VEBAs, and grantor trusts and insurance
policies. Notwithstanding anything to the contrary herein contained, the
assumption of such obligations is not intended to and shall not be construed to
impair the right or ability of Buyer to unilaterally amend or terminate any such
benefit plans and other fringe benefits, or any Company Plan in effect
immediately prior to the Closing Date, at any time after the Closing Date.

      VI.5 Research and Experimental Expenses. Seller will use its reasonable
best efforts to cause to be furnished to Buyer as soon as reasonably
practicable, but in no event more than 180 days after Closing, all information
reasonably requested relating to the base period research expenses and any other
information to allow Buyer to claim research and experimental credits in
accordance with the relevant sections of the Code and treasury regulations
promulgated thereunder.

Harris (see Section III.28 below). The Company also owns some warrants and
common stock of TWA, and some common stock of Continental Airlines which it

                                   Litigation

      The Subsidiary entered into an Agreement with the Florsheim Group, Inc.
(Florsheim) for the survey, engineering and construction management of the
abatement and demolition of the former headquarters building of Florsheim in
Chicago, IL. The Subsidiary subcontracted the abatement and demolition phases of
the project to EHC, Inc. (EHC), who subsequently subcontracted a portion of the
demolition to MasterCraft, Inc. (MasterCraft). The subcontract Agreement
executed between the Subsidiary and EHC includes a provision restricting EHC and
their subcontractors from filing mechanic liens against the property, as well as
a provision to indemnify and hold the Subsidiary harmless from any and all
damages associated with EHC's actions of those of its subcontractors. A work
quality issue arose between EHC and MasterCraft, resulting in EHC terminating
the subcontract Agreement. MasterCraft then filed suit against EHC, claiming
contract breach by improper contract termination. The suit also named the
Subsidiary, Florsheim, and other project development and financing entities, and
includes a demand for damages for $51,000.

      The Subsidiary has answered these charges, and has contacted plaintiff's
counsel to investigate terminating the action against the Subsidiary. Plaintiff
did not object to this approach, and may decide to accept that proposal at a
hearing on the matter scheduled for February 17, 1998. The Subsidiary has also
contacted EHC regarding its obligations to accept defense cost and other
financial responsibilities, which it admits. The Subsidiary management
anticipates that the Subsidiary will ultimately be dismissed from the action.

      GlobalLink Software Licenses

      GlobalLink is an AlliedSignal corporate initiative that focused on
upgrading the desktop and server infrastructure and software at all divisions to
a common level of performance. These upgrades would allow AlliedSignal to roll
out corporate based software applications and economize on desktop support given
the common software / infrastructure.

      Ocean Systems did not receive any hardware improvements from this
initiative. The division did receive, and is being charged, for software
products covered under GlobalLink umbrella. These software products include all
of the following (note that some of these products are not actually in use at
this division but are being assessed none the less):

o 32-bit Desktop Operating System        o LANdesk (Electronic (NT or W95
                                           Inventory Tool - NOT USED)
o Netscape                               o Microsoft Exchange (Email 
o McAfee VirusScan                         Client Licenses - NOT USED)
o Netware 4.1 (Network Operating System  o Attachmate (IBM Connectivity
  -NOT USED)                               Tools)
o Managewise (Remote Desktop             o Office97
  Management Tool - NOT USED)            o Server Tools

This software was purchased at $278 / seat in 1996 and is being amortized over
three-years ($74,319 per year).

If licenses were not part of the sale, the impact to Ocean Systems is as
follows:

o     Little or no impact related to current desktop operating system as most
      are already owned
o     Requires procurement of replacement WEB tool (Netscape) and virus
      protection (McAfee)
o     Impact related to IBM connectivity would depend on new owner IBM access
      requirements
o     Future impact related to desktop upgrades (NT, Office97, Microsoft
      Exchange)

Basis of Premium Charge


1 of 2
<PAGE>

Prior to renewal each year, the Risk Management Department sends each operation
a form to be completed. The form indicates the number of vehicles by category.
Premium is then charged on the number of vehicles in each of five classes
(automobiles, vans, trucks, tractors and buses) as well as three experience rate
levels relating to the operation's past losses.

Short-Term Leased Vehicles
(Less than one year)

For automobiles rented/leased with the Corporate American Express Card within
the United States, no matter which leasing company is used to lease a short-term
vehicle, the insurance waiver for the collision deductible should be accepted.
If not rented/leased with the Corporate American Express Card, it will be up to
the individual operating unit's management to decide whether or not the employee
waives or accepts the waiver for collision deductible. This decision should be
based on the costs/benefits of the operating unit's rental experience.

Use of Personal Automobile on Company Business

The AlliedSignal Inc. Corporate Risk Management Program does not provide
coverage for physical damage to an employee's vehicle or for the employee's
liability to third parties. An employee using their own automobile on company
business must look to their own personal insurance carrier for coverage.

At the discretion of Corporate Management the Corporate Automobile Liability
Policy will provide liability insurance in excess of the employee's personal
automobile liability limits while an employee is using his personal car on
company business.

Local Automobile Insurance Guidelines

Automobile insurance is broken down into 2 main categories:

1.    Automobile Liability for bodily injury and property damage to others

2.    Physical damage to the vehicle to include collision, theft, etc.

The purchase of physical damage insurance is prohibited by Corporate policy.

As respects automobile liability, this subject can be broken down into two more
categories:

A.    Liability arising out of the use of owned or leased vehicles

B.    Liability arising out of the use of vehicles not owned, hired or leased by
      AlliedSignal. This category includes vehicles that are owned by
      AlliedSignal employees and used on company business with the permission of
      the company.

In item "A" above, the owned or leased vehicles must carry local automobile
liability insurance. In most countries, the local vehicle registration laws
require that the operating unit maintain automobile liability insurance for
those vehicles.

Non-owned vehicle coverage is provided as an adjunct to our general liability
program. Such coverage wilt also normally be provided on an admitted basis as
part of the locally issued general or automobile liability policies. It is
important to note, however, that this coverage does not extend to personal use
of employees' vehicles. It is intended to protect AlliedSignal and may,
depending on the discretion of the Risk Management Department, be extended as
excess coverage to its employees as respects liability arising from employees
using personal cars on company business. Therefore, it is imperative that all
employees continue to maintain their own personal automobile insurance.

With respect to the Zurich-American USA policy, it extends on a broader and
excess basis to all categories of automobile liability indicated above, over a
minimum primary limit of $25,000 or the local statutory limit, whichever is
greater.

On the subject of rented automobiles, the major rental firms with whom we deal
provide liability insurance as part of the rental agreement. Our international
program provides insurance protection for both AlliedSignal and the employee,
while on company business, for coverage in excess of that offered by the
automobile contract.

The Zurich-American program does not mandate that the local admitted automobile
insurance be placed with the Zurich-American network facility in the various
countries. However, with all other factors being equal, we strongly encourage
the use of the Zurich-American for the admitted automobile liability program.
Whether or not the Zurich-American is used, the J&H local facility is to be the
broker for the automobile insurances.

OCEAN CARGO INSURANCE INCLUDING WAR RISK

Insurance Company

Fireman's Fund Insurance Company

within the US & Canada), by vessel and air freight for account of AlliedSignal
Inc. and its overseas customers on merchandise incidental to the business of the
insured.

Valuation of goods normally includes prepaid or advanced or guaranteed freight
or other charges incurred prior to shipment, plus 10%. Policy provides for
certain alternative valuation clauses.

Limits of Liability

1.    $15,000,000 per any one vessel or conveyance including aircraft.

      $400,000 per any one household effects shipment

      $50,000 per package shipped by mail or parcel post and $50,000 in any one
      package and/or baggage while in the custody of a messenger whether an
      employee of AlliedSignal Inc. or otherwise.

2.    Shipments originating within the United States and Canada are excluded if
      the destination is also within the US or Canada.

3.    War Risk applies only while goods are carried on overseas vessels or
      aircraft. It does not apply prior to being on-board or after arrival at
      intended port of discharge.

4.    War Risk does not cover loss or damage caused by or resulting from
      commandeering, preemption, requisition, nationalization or seizure or
      destruction under quarantine or customs regulations.

5.    Geographical Limits - coverage is on the basis known as "World to World",
      i.e., from ports and places in the world to ports and places in the world.

6.    All merchandise with exception of Dry Bulk Cargo and Liquid Bulk Cargo is
      insured for "All Risks" conditions. Intracompany shipments are subject to
      a $5,000 deductible. Note, in view of the sensitive nature of our
      products, under deck stowage should always be requested from the Steamship
      Companies.


1 of 6
<PAGE>

Dry Bulk Cargo is insured for "All Risks". However, claims for leakage and/or
shortage and/or loss in weight are subject to a one-half (.5%) deductible
applied to the insured value of the entire shipment.

Bulk Liquid Products are insured:

"All Risks" excluding shortage, leakage, and/or contamination unless caused by
or arising out of the vessel being stranded, sunk, burnt, or in collision.
Contamination resulting from stress of weather is covered.

Claims are payable subject to deductible for normal shortage.

Options are given to cover Bulk Liquid Cargo for:

      a.    "All Risks" excluding unexplained shortage and/or loss in weight.
            Claims for differences between shipped and outturn weights are
            subject to a .5% deductible applied to contents of each tank.

      b.    "All Risks" including coverage for all shortage and/or loss in
            weight subject to deductible of .5% applied to contents of each
            tank.

            Warranties are in effect with respect to tank cleanliness, loading
            and survey requirements.

7.    Temporary detention coverage is provided for goods during interruption of
      transit and in temporary storage for repacking, consolidation, inspection,
      storage or allocation for up to 60 days.

8.    Duty coverage on imports included where required.

9.    Sixty (60) days notice of cancellation.

10.   Foreign storage coverage is provided for goods in storage up to $500,000
      each unnamed location. The risks of Earthquake and Flood are excluded at
      unnamed locations; but these risks may be restored if location is named
      within thirty (30) days of receipt of merchandise. A specific endorsement
      must be secured to name the location and respective limit. Prompt notice
      must be given when goods are placed in storage indicating location, amount
      and goods at risk.

11.   Contingency - For Exports Only

      Depending on the Contracts of Sale, the buyer will arrange their own
      Marine insurance, thus AlliedSignal will not insure the shipment on behalf
      of the buyer under the Corporation's Ocean Marine Insurance Policy. For
      one reason or another, title in the goods may revert to the seller, i.e.,
      by exercise of rights of stoppage in transit or rejection of the goods by
      the buyer. Or the buyer might refuse to pay for the merchandise because of
      loss and/or damage.

      In order to protect AlliedSignal's interest in the preceding, AlliedSignal
      has the option provided such option is exercised prior to any known or
      reported loss to insure all goods and/or merchandise sold to others
      whereby AlliedSignal is not obligated to provide Ocean Cargo insurance for
      the Contingency Interest of AlliedSignal Inc.


2 of 6
<PAGE>

      This coverage will indemnify AlliedSignal for loss incurred due to perils
      insured against under the Corporation's Ocean Marine Insurance Policy.

12.   Exhibitions

      All goods and/or merchandise property of AlliedSignal Inc. while on tour
      and/or display in exhibitions, showrooms and/or trade shows or otherwise
      including all incidental transit are covered under the Marine Insurance
      Program. Excluding exhibitions, showrooms and/or trade shows, etc., in the
      United States.

      The limit of this coverage is $100,000. Excess coverage provided under
      foreign property program.

13.   Increased Value/Difference in Conditions - For Imports Only

      Depending on the Contracts of Sale, AlliedSignal will purchase various
      merchandise from vendors located outside the United States in which the
      Seller will arrange the Ocean Marine Insurance. Thus in the event of loss
      or damage, AlliedSignal will have to rely on the Sellers insurance to be
      reimbursed for the loss.

      In order to fully protect AlliedSignal's interest, AlliedSignal has the
      option, provided such option is exercised prior to any known or reported
      loss, to insure all goods and/or merchandise purchased by AlliedSignal on
      Cost, Insurance, Freight (C.I.F.) or other terms of purchase whereby the
      Marine insurance is provided by the seller or others for Difference in
      Conditions and Increased Value as stated in the Corporation's Ocean Marine
      Insurance Policy.

Policy Period

5/1/94 until cancelled.

Notice and Handling of Claims

In the event of loss:

- -     Make every reasonable effort to minimize the loss. Act as a prudent
      uninsured cargo owner would. Reasonable expenses incurred in minimizing a
      loss are recoverable.

- -     Take proper delivery exceptions and file claim against the transportation
      carrier. Do the necessary to preserve insurer's recovery rights against
      the carrier.

- -     Promptly report the loss to AlliedSignal's Risk Management Department
      (domestic shipment and imports) or insurer's settling agent (exports).

INTERNATIONAL SHIPMENTS

Import Shipments (From Foreign to U.S.)

      Inspect Cargo

      Before accepting your shipment from the carrier, carefully inspect the
      cargo. If damages or shortages are observed, make the appropriate notation
      on the delivery receipt. If damage is


3 of 6
<PAGE>

      suspected but not readily apparent, note on the delivery receipt "Subject
      to Inspection." At this time, take any practical steps to minimize the
      loss.

File Claim on Carrier

      Promptly file written claim against the transportation carrier. (See
      sample claim letter).

      Prompt notice is very important as claims can be disallowed within a short
      period. For example, a claim for damage to an air shipment must be filed
      within seven days. FAILURE TO FILE PROMPTLY AGAINST THE CARRIER MAY
      PREJUDICE YOUR INSURANCE CLAIM.

File Insurance Claim

Promptly report the loss to AlliedSignal's Risk Management Department who will
in turn notify insurer.

If the loss exceeds $5,000 or involves unusual circumstances, the initial report
should be made by telephone, so that insurer might arrange to have a surveyor
inspect the damages promptly. The surveyor issues his report to insurer relating
the nature, cause and extent of loss.

Regardless of the amount of the loss, do not dispose of any damaged cargo until
settlement is agreed or advised to do so by the surveyor.

Claims Documentation

Cargo claims are essentially adjusted on the basis of documentation. It is your
obligation to demonstrate your claim by providing the Risk Management Department
with documentation which shows the loss was incurred during transit and which
substantiates the values being claimed.

The following documents are required for claims on imports:

- - File an itemized statement as to the amount claimed
- - Bills of Lading (Ocean, Air and Inland). If claim is for non-delivery of an
  entire shipment all original ocean bills of lading are required.
- - Commercial Invoice
- - Packing List
- - Consumption Entry Report (if duty is insured).
- - Copy of claim against the carrier and reply, if any.
- - Delivery Receipt showing exceptions.
- - Trailer Interchange Receipt (for containerized shipments).
- - Carrier's confirmation of non-delivery (when claiming non-delivery of an
  entire shipping package).
- - Repair/reconditioning invoices or estimates.

This list includes the documents commonly needed to demonstrate a cargo claim.
Be sure to submit any other documentation which would substantiate your claim.

General Average

In case a General Average is reported, the Average Adjusters require either a
cash deposit or a General Average Guarantee from an Underwriter authorized to do
business in the country where security is


4 of 6
<PAGE>

taken.

The cargo generally will not be released until the Average Adjusters receive the
Average Bond or Average Agreement and the General Average Guarantee.

Be prepared to furnish identification of the Average Adjuster, details of the
casualty, description and value of cargo, the Bill of Lading number and date,
and identification of the insurance declaration. Alexander & Alexander will then
arrange for the Underwriter to issue a General Average Guarantee or to post a
cash deposit.

The documentation required is as follows:

a. Invoice
b. Bill of Lading
c. Copy of the signed Average Bond or Average Agreement
d. Insurance Certificate or Insurance Declaration

After the cargo is released for delivery and the documentary requirements
fulfilled all subsequent claim negotiations will be between the Average Adjuster
and Underwriter.

Export (U.S. to Foreign) and Foreign (Foreign to Foreign) Shipments

On shipments terminating in foreign countries, the consignee basically follows
the same claim procedure as you do for imports. Instead of reporting the loss to
AlliedSignal's Risk Management Department, however, the consignee contacts the
insurer's survey agent as listed on the Special Marine Policy which he receives
with the shipping documentation.

The consignee pays the survey fee and submits his claim (including the survey
fee) to the nearest insurer settling agent shown on the Special Marine Policy.
He submits the Special Marine Policy and the survey report in addition to those
documents listed above for import shipments.

This claim procedure is clearly outlined on the reverse of the Special Marine
Policy.

HOUSEHOLD AND PERSONAL EFFECTS SHIPMENTS

Employees household goods and personal effects moves are insured against all
risks of physical loss or damage from an external cause up to the value declared
on AlliedSignal's relocation forms.

Domestic and Foreign to U.S. Moves

      Inspect Cargo

      Before accepting delivery, inspect your goods and note any apparent
      damages on the delivery receipt. If you do not have an opportunity to make
      a thorough inspection, sign the receipt with the notation "Subject to
      further inspection."

      File Claim Against the Moving Company

      In the event of damage or shortage, promptly notify the moving company by
      telephone and then follow-up with a written notice of claim. Under a
      special arrangement with the insurer, the moving


5 of 6
<PAGE>

      company will inspect the damages and settle the claim directly with you.

      Claims Documentation

      The following documents should usually be submitted to the moving company:

       -   Bill of Lading
       -   Valued Inventory
       -   Packing List/Inventory
       -   Delivery Receipt
       -   Repair Bill or Estimates
       -   Completed Claim Form (supplied by the moving company)
    
Foreign Moves

In the event of loss or damage to your goods when delivered to a foreign
destination, secure the above claim documentation (Household and Personal
Effects Shipments) and forward to the Risk Management Department.

GENERAL REMARKS

These procedures will serve as a guideline for everyday cargo claims handling.
If you encounter any difficulties in handling a particular claim, contact the
Risk Management Department for assistance.

You should also be sure to promptly notify the Risk Management Department of any
serious cargo loss.

GLOBAL PROPERTY DAMAGE AND BUSINESS INTERRUPTION

Insurance Company

The insurance company is American International Underwriters for Allied's
International locations. In North America the primary insurers are Reliance,
Houston Casualty, National Union and Protection Mutual. These same insurers,
plus other U.S. & European insurers participate both in the primary layer, as
well as the excess layers.

Coverage

This is a blanket policy* covering the Corporation against loss or damage, on a
replacement cost basis**, to real and personal property, or the property of
others for which the Corporation is responsible at locations worldwide
(including while in transit). The policy insures against all risk of direct
physical loss or damage from any external cause, including boiler and machinery
breakdown and is subject to normal exclusions such as wear and tear, gradual
deterioration, extremes of temperature, war, nuclear and other exclusions
commonly considered uninsurable or the subject of other insurance such as
employee dishonesty.

The Policy covers Boiler and Machinery up to the full limit per occurrence. This
policy also provides business interruption insurance and contingent business
interruption insurance which is designed to pay for loss of profits and
continuing costs which result from damage to insured property and/or to those of
a supplier or receiver by an insured peril.

The policy has been extended to cover damage to electronic data processing
equipment; and for costs of reproducing media from duplicates or originals only.
Some limited amount of full reproduction expenses is provided. Included therein
is business interruption and/or extra expense coverage which provide for
reimbursement for loss of income and/or the assurance of funds to meet the
additional expenses incurred in returning to normal operations following an
Insured incident.

The policy automatically (subject to reporting to underwriters in a certain time
frame) covers new and acquired property and the interest of any company or
corporation which during the period of the policy is merged with, becomes a
subsidiary of, or becomes controlled by Allied or any subsidiary of Allied.

* This policy covers all Allied Signal's locations on a blanket basis (except
certain EMS locations, which are covered for $1.2 Billion each occurrence) which
means the entire amount of insurance can be applied to a single location.

** In the event of loss or damage to real and/or personal property which is not
repaired, rebuilt or replaced, such property will be valued at Actual Cash
Value.

inventory and estimated business interruption values as of December 31 each
year. In addition, loss experience is considered in expensing the cost of the
Insurance based upon each business area's proportion of total values.

Notice of Loss

The proper reporting of claims is important as it effects:

o     The speed of loss settlement

o     The prejudicing of your rights against the insurance company caused by
      reporting delays, thereby violating the insurance policy conditions.

o     The proper adjusting of the claim amount..

For all losses that may result in an insurable claim you should notify the
Corporate Risk Management Department and if the loss occurs outside North
America, you should immediately notify your local insurance broker when:

o     The claims could exceed $10,000

o     There is a possibility that the claim will be denied by the local
      insurance company

o     There is a dispute as to the settlement amount of the claim

All losses should be reported to the local broker and the Corporate Risk
Manager. Those claims insured by the Corporate Ocean Maine Cargo program should
be reported in accordance with the procedures set forth by the Corporate Risk
Management Department and reported to the Corporate ocean marine cargo broker in
New York.

which is allocated annually. Included in the administrative cost are Travelers'
engineering services (inspections, schools, etc.), state taxes, special fund
assessments, cost of excess insurance and expense and profit of Travelers.
Secondly, there is a quarterly charge that includes claim losses based upon
total incurred liability, up to a maximum of $250,000 per occurrence and a
claims administration fee. Claim losses include all new claims filed during the
current period plus increase and/or decrease in the incurred liability for prior
periods. Claims and the incurred liability appear on the quarterly loss run. The
claims administration fee is 11% for accidents occurring prior to April 1, 1986,
and 8% after April 1, 1986.

Locations in State Funds (Wyoming, West Virginia, Nevada, North Dakota) pay
premium directly to a division of the respective State Governments. The State
Agency is responsible for payment of statutory benefits and administration of
the claims.

The cost of this premium is allocated based upon payroll and estimated claims
costs.

For accidents that occur on or after April 1, 1996, Kemper Insurance Company is
the workers' compensation claims administrator for locations in Arizona, Florida
and New Jersey. Travelers Insurance retains responsibility for claims that
occurred in these states before April 1, 1996. Travelers also retains
responsibility for claims in all other states.

The following Claims Service Requirements (CSR) will be followed by both the
Travelers Insurance Company and Kemper Insurance Company in administering our
claim files. Travelers refers to these instructions as Special Account
Communication (SAC). Kemper uses the title National Account Claim Bulletin.

ALLIEDSIGNAL CLAIM SERVICE REQUIREMENTS (CSR)

Acknowledgement - Workers' Compensation


2 of 8
<PAGE>

The Workers' Compensation system has been programmed to produce a claim
acknowledgment printout. All claim acknowledgments will be mailed to: The
location submitting the loss.

Adjuster Notes - Workers' Compensation

Instant access to your claim information is available through our adjuster notes
facility. The customer will see the development of the specific claim especially
in the two key areas of reserve rationale and action plan for resolution.
Sharing of information is the key.

Quarterly Contact - Workers' Compensation

We have agreed with both AlliedSignal officials and the producer that Workers'
Compensation supervisory personnel will maintain a program of open
communications between Travelers, Kemper and AlliedSignal personnel in
conjunction with our handling of Workers' Compensation cases. Each AlliedSignal
location will have a Workers' Compensation coordinator, designated by the plant
manager, who will be our contact. The Claim Supervisor file handler handling
Workers' Compensation claims should maintain at least quarterly contact with the
Workers' Compensation coordinator designated at each location, so that cases of
interest may be reviewed, or any other topics can be discussed.

File Review Meetings - Workers' Compensation

AlliedSignal Inc. has agreed to hold file review meetings as needed. If
requested by AlliedSignal, these file review meetings will be held to discuss
open claim files designated by the customer or recommended by Travelers/Kemper
as cases significant in nature. After each file is discussed, a joint action
plan should be agreed to and made part of the file. These meetings should take
place in our office or the AlliedSignal location.

Requests for Special Reports or Services

Occasionally, the AlliedSignal Workers' Compensation Coordinator will ask for
special reports or implementation of a program/service that is beyond the
services outlined in these instructions. While close local communications are
encouraged, any such arrangement (to be performed on a routine basis) should be
submitted to the Claim Account Executive for discussion with AlliedSignal Risk
Management. This will assure continuity in the services provided AlliedSignal
Inc.

Annual Visitations

On an annual basis, a personal visit will be made to the AlliedSignal location
to review the CSR instructions, application of best practices, communications
and any problem areas. During these meetings a detailed review of the CSR
instructions should be completed to insure we are in compliance. This visitation
should be completed during the first quarter and may be part of a regular
quarterly meeting. The AlliedSignal Inc. annual visitation form must be
completed and sent to the Claim Account Executive.

"Red Flag" Claims - Workers' Compensation

There will be occasions when the field office will receive notification from the
customer expressing special interest in a claim. This will be termed a "Red
Flag" claim by AlliedSignal. This special interest may be expressed at the time
of first notice, or at any other time while the claim remains open. When a claim
is submitted by the AlliedSignal location and a form letter is attached to the
first report identifying


3 of 8
<PAGE>

the claim as a "RED FLAG" case, we have agreed to the following special handling
guidelines:

o     Acknowledge receipt of the case to the AlliedSignal representative who
      submitted it.

o     The claim handler will initiate a telephone call to the AlliedSignal
      representative to establish a game plan for investigation and management
      of the case. The claim handler will outline in a letter to AlliedSignal
      location the proposed investigation and action to be completed.

o     As the case develops, we will maintain communications with the
      AlliedSignal location.

o     After completion of the investigation, we will discuss the case by
      telephone with the AlliedSignal location and explain our decision on
      compensability. If there is a difference of opinion on compensability and
      agreement cannot be reached, the AlliedSignal location will contact Tim
      Cummings and Travelers offices should contact the Claim Account Executive.

If any problems or disagreements arise, notify the Claim Account Executive.

Employer's Liability Claims - Workers' Compensation

Any time an employer's liability claim is established, acknowledgment of the
claim should be sent to: (I-1).

Independent Medical Exams and Medical Consultation Referrals After 60 Days of
Disability - Workers' Compensation

When an employee has been disabled or is anticipated to be disabled for 60 days
or more an independent medical examination or medical consultation referral
should be considered. The supervisor managing the claims should discuss the
feasibility of an independent exam or consultation with the location submitting
the claim. If the location submitting the claim AGREES NOT to schedule IME or
refer the employee for a medical consultation the claim file should be
documented accordingly.

Medical Services Department

AlliedSignal Inc. has an in house Medical Services Department which is available
for consultation on any claim. This medical staff is a valuable resource and we
should take advantage of their service. Members of this department may contact
you directly on selected cases. If you or our medical vendor require the
assistance of AlliedSignal's medical staff, contact (I-1).

Some of the locations, especially the larger ones with a medical representative
are interested in receiving copies of the medical reports. We should attempt to
accommodate the customers needs for this medical information.

Alternative and Modified Work - Workers' Compensation

AlliedSignal Inc. has put in place an aggressive alternative and modified work
program in all their locations. Before making any lost time benefit payments you
should discuss with the AlliedSignal location whether the injured worker has
returned or will return to alternative or modified work. Continuous contact with
the AlliedSignal Workers' Compensation coordinator should be maintained on any
employee who is receiving lost time benefits to return these employees to work.


4 of 8
<PAGE>

The process for returning employees to Alternative Work at AlliedSignal is to
determine the capabilities of the employee. The AlliedSignal location will
determine what restrictions they can accommodate. It is most important the
AlliedSignal location know the current capabilities of every disabled employee.
The AlliedSignal location representative is to be kept current on the medical
status of disabled employees. Every effort should be made to set target dates
for return to regular or alternative work.

o     The purpose of this process is to aggressively track for return to work,
      employees on temporary total disability. If the nature of the claim allows
      for a more rapid assessment and finalization of the claim, we would
      certainly encourage you to identify your recommendations to AlliedSignal.
      If an employee is paid Temporary Total benefits, we will provide the
      following:

After 90 and 180 days on temporary total disability, identify in a report to the
location Workers' Compensation Coordinator, copy T. Cummings the following
information. Send a copy of the 90 day report to the Plant Manager.

      90 Days of Temporary Total

      -     Basis for disability - Why is the employee out of work?

      -     What efforts have been made to find alternative work?

      -     When will the employee be returning to work?

      -     Identify the chances of the employee ever returning to alternative
            work, regular job or permanent modified job at AlliedSignal. What
            can the locations do to provide temporary or permanent job modified
            job at AlliedSignal. What can the locations do to provide temporary
            or permanent job modification?

      -     Should we consider Rehabilitation/Retraining?

      -     Provide an action plan to return the employee to work or to resolve
            the claim.

      -     If the location has determined that they cannot take this employee
            back to work, we need to identify to the locations the possible cost
            of this claim. What are the alternatives for resolving this claim
            and the cost structure of each?

      180 of Temporary Total

      -     Same information as in 90 day report.

      -     At this time, the report must identify the specific action with a
            time table and the financial consequence that will be taken to
            resolve this claim.

      -     Subsequent reports as determined by the claim and the time table for
            resolution.

Vocational Rehabilitation - Workers' Compensation

Before assigning a case for vocational rehabilitation we will discuss the
reason(s) for the vocational rehabilitation with the location submitting the
loss. The AlliedSignal location may have other pertinent information concerning
the injured party that will assist in the vocational rehabilitation process.

Claim Checks - Temporary Total, Permanent Partial & Temporary Partial
Workers' Compensation

All checks issued in payment of Temporary Total, Permanent Partial and Temporary
Partial disability benefits are to be made payable to the injured employee and
mailed to the customer at the customer's location reporting the loss. If that
practice is not permitted in the state involved, mail the check to the employee
and furnish the insured's location the Workers' Compensation payment summary.

Serious Catastrophic Injuries - Workers' Compensation

AlliedSignal Risk Management Department should be notified immediately. The
following injuries are examples, but are not intended to be all encompassing.

Fatalities.
Amputation Of One Or More Extremities.
Severe Brain Or Brain Stem Injury.
Second Or Third Degree Burns.
Heart Cases.
Disability Of 60 Days.

including facts of the accident, nature and extent of injuries as well as
pertinent investigation details to: The location submitting the loss, copies to
(I-1) and (B).

The insured has agreed to utilize our regular panel and staff attorneys in
defense of law suits. However, on certain cases the customer may prefer to use
their own outside counsel for cases in litigation. We have agreed to accommodate
these exception requests.

If you feel that working with the law firm chosen by the customer will prove to
be a problem, contact the Claim Account Executive. If a decision is made to
change and assigned Defense Attorney, concurrence must be received from
AlliedSignal's Risk Management Department. Direct a letter outlining the facts
for the basis of the proposed change to: (I-1), copy to the Claim Account
Executive.

to review the case with the customer, before settlement negotiations are
initiated. This is to be accomplished by letter, setting forth details of the
case, and explaining our intentions for handling. This letter is to be directed
to: The location submitting the loss.

Actuarial Methods and Assumptions

================================================================================

Actuarial Valuation for Accounting Purposes

Actuarial Cost Method
Projected Unit Credit Cost Method*.

Market-Related Value of Assets

Market-related value equals fair market value adjusted for investment earnings
and losses.  Such investment experience is reflected in market-related value as
follows:

o  Actual earnings on fixed-income investments are reflected immediately;

o  Expected earnings on other assets are reflected immediately;

o  Actual earnings on other assets less expected earnings on other assets are
   reflected ratably over three years--one-third in the year folowing the
   gain or loss, two-thirds in the second year following, and 100% in all
   subsequent years.

The Company reported that fixed income investments represented 28.3% and 29.3%
of total trust assets as of December 31, 1996 and December 31, 1995,
respectively. The Company also reported 1996 rates of return of 8.2% for the
fixed income segment and 16.6% for the total trust. Based on this information,a
1996 rate of return of 19.9% was calculated for the other assets of the trust.

Actuarial Assumptions

(1) Discount Rate: 7.00% compounded annually.

(2) Expected Long-Term Rate of Return on Assets: 10% per year.

(3) Compensation Increases**: Present compensation is assumed to increase 5%
    per year to retirement.

(4) Retirement: For Salaried plan, an average retirement age of approximately 
    61, with incidence at specific ages as follows:

=======================================================
Age       Probability             Age       Probability
=======================================================
 55                5%              61               20% 
 56                6%              62               30% 
 57                7%              63               20% 
 58                8%              64               30% 
 59                9%              65              100%
 60               10%                                     

*Standard Unit Credit for non-pay-related plan.
**Pay-related plan only.

                                Schedule 6.5(b)

Actuarial Methods and Assumptions (continued)

================================================================================

      For Bendix Hourly: The assumed retirement age is based upon the early
      retirement provisions of the particular location according to the
      following:

      (a)   For units providing "30-and-out" retirements, the retirement age is
            the later of age 56 or the completion of 30 years of service but not
            later than age 62 with ten years of service;

      (b)   Age 64 for units providing unreduced benefits at age 62;

      (c)   Otherwise, age 65.

      All early retirements are assumed to be voluntary. No involuntary
      retirements or plant shutdowns are assumed.

(5)   Mortality:

      Nondisabled Lives     1971 Group Annuity
      Disabled Lives        1977 Railroad Board

(6)   Withdrawal:

      (a)   Salaried Plan: Table B-1 (See Page 3).

      (b)   Hourly Plan: Table B-2 (See Page 3).

(7)   Disability: Table B-3 (See Page 3).

(8)   Social Security: Future wage indices are based on an increase of 4.5% per
      year. Past wages are estimated on the basis of Social Security Index
      Factors. Future cost of living increases are assumed to be 4% per year.

(9)   Marital Status: With regard to any preretirement surviving spouse annuity
      provisions of the plan, the assumption is made that the male of the couple
      is three years older than the female and that 85% of male participants and
      65% of female participants are married.

(10)  IRC Section 415 Limits: Reflect the single and dual plan limits based on
      estimated, defined contribution account balances, and percentage of
      employees electing joint and survivor payment forms. This limit is
      projected at an assumed 4% annual cost-of-living incrase rate.

(11)  IRC Section 401(a)(17) Pay Limit: $160,000 for 1997. This limit is
      projected at an assumed 4% annual cost-of-living increase rate.

Basis of Premium Charge


3 of 6
<PAGE>

Values for property damage and business interruption are completed and submitted
to the Risk Management Department annually. Premium is determined on the basis
of trended building, machinery and equipment replacement values, together with
inventory and estimated business interruption values as of December 31 each
year. In addition, loss experience is considered in expensing the cost of the
Insurance based upon each business area's proportion of total values.

Notice of Loss

The proper reporting of claims is important as it effects:

      o     The speed of loss settlement
      o     The prejudicing of your rights against the insurance company caused
            by reporting delays, thereby violating the insurance policy
            conditions.
      o     The proper adjusting of the claim amount.

For all losses that may result in an insurable claim you should notify the
Corporate Risk Management Department and if the loss occurs outside North
America, you should immediately notify local insurance brook when:

      o     The claims could exceed $10,000
      o     There is a possibility that the claim will be denied by the local
            insurance company
      o     There is a dispute as to the settlement amount of the claim

All losses should be reported to the local broker and the Corporate Risk
Manager. Those claims insured by the Corporate Ocean Maine Cargo program should
be reported in accordance with the procedures set forth by the Corporate Risk
Management Department and reported to the Corporate ocean marine cargo broker in
New York.

                              ASSIGNMENT AGREEMENT

      THIS ASSIGNMENT AGREEMENT dated as of March 4, 1998 is entered into by
and between L-3 COMMUNICATIONS CORPORATION, a Delaware corporation
("Assignee"), and FAP TRUST, a Connecticut trust ("Assignor").

                                   WITNESSETH

      WHEREAS, Assignor is a party to a Stock Purchase Agreement dated as of
February 9, 1998 (the "Stock Purchase Agreement") pursuant to which Seller
intends to acquire all of the outstanding capital stock of Ilex Systems, Inc.
(the "Company"); and

      WHEREAS, pursuant to the Stock Purchase Agreement, Assignor, the Company,
all of the stockholders of the Company (the "Sellers") and The First National
Bank of Chicago, a national banking association ("Escrow Agent"), have entered
into that certain Escrow Agreement dated as of February __, 1998 (the "Escrow
Agreement") for the purpose of establishing a fund to satisfy certain
indemnification obligations of the Sellers that may arise under the Stock
Purchase Agreement and to facilitate the payment of the cash purchase price
adjustment contemplated thereby; and

      WHEREAS, Assignor and Assignee have entered into an Asset Purchase
Agreement dated as of February 10, 1998 (the "Asset Purchase Agreement")
pursuant to which Assignee will acquire substantially all of the assets and
assume substantially all of the liabilities of the Company; and

      WHEREAS, in connection with the Asset Purchase Agreement and the
transactions contemplated thereby, Assignor desires to assign to Assignee its
entire right, title and interest in, under and to the Escrow Agreement, and
Assignee desires to take such assignment from Assignor, all upon the terms and
conditions set forth below:

      NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

      1. Assignment of the Escrow Agreement. Assignor hereby assigns to
Assignee all of Assignor's right, title and interest in, under and to the
Escrow Agreement, and Assignee hereby assumes all of Assignor's duties and
obligations under the Escrow Agreement.

      2. Assertion of Claims Under the Escrow Agreement. Assignor and Assignee
understand that any and all claims which Assignee may have under the Escrow
Agreement will in most instances, but not in all, be based on facts and
circumstances that constitute both breaches of certain representations,
warranties and covenants of Assignor contained in the Asset Purchase Agreement
and breaches of similar representations, warranties and




<PAGE>


covenants of the Company and the Sellers contained in the Stock Purchase
Agreement. Accordingly, Assignor and Assignee agree as follows:

            (i) For purposes of this Section 2, capitalized terms used but not
      otherwise defined herein shall have the respective meanings given to them
      in the Escrow Agreement.

            (ii) Assignor shall promptly provide written notice to Assignee
      upon its becoming aware of any facts or circumstances that give rise to a
      breach of representation, warranty or covenant under the Stock Purchase
      Agreement. Assignee shall promptly provide written notice to Assignor
      upon its becoming aware of any facts or circumstances that give rise to a
      breach of representation, warranty or covenant under the Asset Purchase
      Agreement.

            (iii) Assignee agrees that it will promptly provide Escrow Agent
      with a Notice of Claim in all instances where Assignee's claims pursuant
      to the Asset Purchase Agreement may also be asserted by Assignor pursuant
      to the Stock Purchase Agreement (a "Matching Claim"). The following
      procedure shall be followed by Assignor and Assignee in connection with
      each Matching Claim:

                  (a) Upon submission by Assignee to Escrow Agent of a Notice
            of Claim with respect to any Matching Claim, Assignee shall direct
            Escrow Agent in writing to make any disbursements required in
            respect thereof directly to Assignee; and

                  (b) Upon the determination of the amount, if any, payable to
            Assignee with respect to such Matching Claim, whether by
            negotiation or litigation, and disbursement by Escrow Agent to
            Assignee of such amount out of the Escrow Fund in respect of any
            Matching Claim, Assignee agrees that such Matching Claim shall be
            deemed fully paid and satisfied and neither Assignor nor Escrow
            Agent shall have any further liability to Assignee with respect to
            such Matching Claim, nor shall Assignee have any right to seek any
            additional payments out of the Escrow Fund pursuant to the Asset
            Purchase Agreement with respect to such Matching Claim.

            (iv) In consideration of the mutual promises contained in this
      Agreement, Assignee agrees that it will, if known, provide Escrow Agent
      with a Notice of Claim in respect of any and all claims that may be
      asserted by Assignor pursuant to the Stock Purchase Agreement but may not
      be asserted by Assignee pursuant to the Asset Purchase Agreement (an
      "Assignor Claim"). The following procedure shall be followed by Assignor
      and Assignee in connection with each Assignor Claim:

                  (a) Upon submission by Assignee to Escrow Agent of a Notice
            of Claim with respect to any Assignor Claim, Assignee shall direct
            Escrow Agent in writing to make any disbursements required in
            respect thereof directly to Assignee; and


                                      -2-


<PAGE>


                  (b) Upon determination of the amount, if any, payable to
            Assignee with respect to such Assignor Claim, whether by
            negotiation or litigation, and disbursement by Escrow Agent to
            Assignee of such amount out of the Escrow Fund in respect of any
            Assignor Claim, Assignee shall within two business days thereafter
            remit to Assignor by certified check or wire transfer to an account
            designated by Assignor in writing an amount equal to the amounts
            disbursed to Assignee with respect to such Assignor Claim, and
            Assignor agrees that its claim shall be deemed fully paid and
            satisfied upon receipt of such certified check or wire transfer and
            that neither Assignee nor Escrow Agent shall have any further
            liability to Assignor with respect to that claim, nor shall
            Assignor have any right to seek any additional payments out of the
            Escrow Fund pursuant to the Stock Purchase Agreement with respect
            to that claim. Assignee shall not in any way be responsible to
            Assignor with respect to any such claim except for the requirement
            to deliver to Assignor amounts disbursed to Assignee with respect
            to such claim from the Escrow Fund.

            (v) Assignee agrees to pursue any Matching Claim only under the
      claims procedures set forth in this Agreement and the Escrow Agreement.

            (vi) Assignee shall promptly deliver to Assignor copies of any and
      all Award Notices, Notices of Claims, Notices of Releases, Objections and
      Withdrawal Notices received by it pursuant to Section 5 of the Escrow
      Agreement.

            (vii) Assignor and Assignee shall cooperate with each other
      regarding the submission of any and all Notices of Claims to Escrow Agent
      in connection with the Escrow Agreement, and each of them agree to take
      any and all such reasonable actions that either of them deem necessary or
      appropriate to otherwise effectuate the purpose and intent of this
      Section 2.

      3. Counterparts. This Agreement may be executed in multiple counterparts,
each of which shall be deemed to be an original but all of which together shall
constitute one and the same instrument.

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

      5. Arbitration. Any dispute under this Agreement which is not settled by

rules then in effect of the Judicial Arbitration and Mediation Service. Each
party shall bear its own costs and attorneys' and witness' fees. The prevailing
party in any arbitration, as determined by the arbitration panel, shall be

party's costs and reasonable attorneys' fees. In making any such award, the
arbitration panel shall take into consideration the outcome of the proceeding
and the reasonableness of the conduct of each such party in connection with the
dispute, in light of
