                       % SENIOR SUBORDINATED NOTES DUE 2008 
                        INTEREST PAYABLE      AND 

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

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

   The Notes will be general unsecured obligations of L-3 Communications, 
subordinate in right of payment to all existing and future Senior Debt of L-3 
Communications. As of December 31, 1997, after giving pro forma effect to the 
1998 Acquisitions and the Offerings, and application of the net proceeds 
therefrom, L-3 Communications would have had approximately $433.6 million of 
indebtedness outstanding, of which $58.6 million would have been Senior Debt 
(excluding letters of credit). See "Capitalization". 

   Concurrently with the Notes Offering, Holdings is publicly offering in the 
United States and internationally         shares of its Common Stock, par 
value $.01 per share (the "Common Stock"). The closing of the Notes Offering 
is conditioned upon the closing of the offering of Common Stock (the "Common 
Stock Offering" and, together with the Notes Offering, the "Offerings"). 
Prior to the consummation of the Common Stock Offering, affiliates of Lehman 
Brothers Inc. own 49.0% of the outstanding capital stock of Holdings. See 
"Ownership of Capital Stock". 

   FOR A DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED IN 
CONNECTION WITH AN INVESTMENT IN THE NOTES, SEE "RISK FACTORS" BEGINNING ON 
PAGE 10. 
    

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES 
  AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION   NOR HAS THE 
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED 
     UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION 
                    TO THE CONTRARY IS A CRIMINAL OFFENSE.

   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, 
groundand 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

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 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 

                                3           
<PAGE>
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 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 
    

                                4           
<PAGE>
    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 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 vertically enhance its product base through internal research and 
    development efforts as well as selective acquisitions and horizontally add 
    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.

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,

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. 
At March 31, 1998, Messrs. Lanza and LaPenta and certain other members of 
management collectively owned 17.8%; the Lehman Partnership owned 49.0%; and 
Lockheed Martin owned 33.2% of the outstanding capital stock of Holdings.

                                 RISK FACTORS 

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

SUBSTANTIAL LEVERAGE 

   
   The Company is highly leveraged as a result of substantial indebtedness 
incurred in connection with the L-3 Acquisition and the 1998 Acquisitions. 
After giving pro forma effect to the L-3 Acquisition, the 1998 Acquisitions 
and the Offerings, the Company would have had $430.9 million of indebtedness 
outstanding, of which $54.3 million would have been Senior Debt (excluding 
letters of credit), and the Company's ratio of earnings to fixed charges 
would have been 1.3x for the year ended December 31, 1997. The Company may 
incur additional indebtedness in the future, subject to limitations imposed 
by its debt instruments, including the Senior Credit Facilities and the 
Indenture. 

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

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

ACQUISITION STRATEGY 

   The Company's strategy includes pursuing additional acquisitions that will 
complement its business. There can be no assurance, however, that the Company 
will be able to identify additional acquisition candidates on commercially 
reasonable terms or at all or that, if consummated, any anticipated benefits 

                               10           
<PAGE>
will be realized from such future acquisitions. In addition, the availability 
of additional acquisition financing cannot be assured and, depending on the 
terms of such additional acquisitions, could be restricted by the terms of 
the Senior Credit Facilities and/or the Indentures. 

   The process of integrating acquired operations, including the 1998 
Acquisitions, into the Company's existing operations may result in unforeseen 
operating difficulties and may require significant financial and managerial 
resources that would otherwise be available for the ongoing development or 
expansion of the Company's existing operations. Possible future acquisitions 
by the Company could result in the incurrence of additional debt, contingent 
liabilities and amortization expenses related to goodwill and other 
intangible assets, all of which could materially adversely affect the 
Company's financial condition and operating results. 

SIGNIFICANT CUSTOMERS 

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

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

RISKS INHERENT IN GOVERNMENT CONTRACTS 

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

   Companies engaged primarily in supplying defense-related equipment and 
services to government agencies are subject to certain business risks 
peculiar to the defense industry. These risks include, among other things, 
the ability of the Government to: (i) suspend unilaterally the Company from 
receiving new contracts pending resolution of alleged violations of 
procurement laws or regulations, (ii) terminate existing contracts, (iii) 
audit the Company's contract-related costs and fees, including allocated 
indirect costs, and (iv) control and potentially prohibit the export of the 
Company's products. 

   All of the Company's Government contracts are, by their terms, subject to 
termination by the Government either for its convenience or for default of 
the contractor. Termination for convenience provisions provide only for the 
recovery by the Company of costs incurred or committed, settlement expenses 
and profit on work completed prior to termination. Termination for default 
provisions provide for the contractor to be liable for excess costs incurred 
by the Government in procuring undelivered items from another source. In 
addition to the right of the Government to terminate, Government contracts 
are conditioned upon the continuing availability of Congressional 
appropriations. Congress usually appropriates funds for a given program on a 
fiscal-year basis even though contract performance may take 

                               11           
<PAGE>
more than one year. Consequently, at the outset of a major program, the 
contract is usually partially funded, and additional monies are normally 
committed to the contract by the procuring agency only if, as and when 
appropriations are made by Congress for future fiscal years. Foreign defense 
contracts generally contain comparable provisions relating to termination at 
the convenience of the government. 

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

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

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

RISKS ASSOCIATED WITH FIXED PRICE CONTRACTS 

   The Company's products and services are provided primarily through fixed 
price or cost plus contracts. Approximately 64% of the Company's pro forma 
sales in 1997 were attributable to fixed price contracts. The financial 
results of long-term fixed price contracts are recognized using the 
cost-to-cost percentage-of-completion method. As a result, revisions in 
revenues and profit estimates are reflected in the period in which the 
conditions that require such revisions become known and are estimable. The 
risks inherent in long-term fixed price contracts include the difficulty of 
forecasting costs and schedules, contract revenues that are related to 
performance in accordance with contract specifications and potential for 
component obsolescence in connection with long-term procurements. Failure to 
anticipate technical problems, estimate costs accurately or control costs 
during performance of a fixed price contract may reduce the Company's 
profitability or cause a loss. Although the Company believes that adequate 
provisions for losses for its fixed price contracts are reflected in its 
financial statements, no assurance can be given that these provisions are 
adequate or that losses on fixed price and time-and-material contracts will 
not occur in the future. 

TECHNOLOGICAL CHANGE; NEW PRODUCT DEVELOPMENT 

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

                               12           
<PAGE>
Discussion and Analysis of Financial Condition and Results of Operations". 
There can be no assurance that the Company will successfully identify new 
opportunities and continue to have financial resources to develop new 
products in a timely or cost-effective manner, or that products and 
technologies developed by others will not render the Company's products and 
systems obsolete or non-competitive. 

ENTRY INTO COMMERCIAL BUSINESS 

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

COMPETITION 

   The communications equipment industry for defense applications and as a 
whole is highly competitive. Declining defense budgets and increasing 
pressures for cost reductions have precipitated a major consolidation in the 
defense industry. The DoD's increased use of commercial off-the-shelf 
products and components in military equipment is expected to increase the 
entrance of new competitors. In addition, consolidation has resulted in 
delays in contract funding or awards and significant predatory pricing 
pressures associated with increased competition and reduced funding. The 
Company expects that the emergence of merchant suppliers will increase 
competition for OEM business. The Company's ability to compete for defense 
contracts depends to a large extent on the effectiveness and innovativeness 
of its research and development programs, its ability to offer better program 
performance than its competitors at a lower cost to the Government customer 
and its readiness in facilities, equipment and personnel to undertake the 
programs for which it competes. In some instances, programs are sole source 
or work directed by the Government to a single supplier. In such cases, there 
may be other suppliers who have the capability to compete for the programs 
involved, but they can only enter or reenter the market if the Government 
should choose to reopen the particular program to competition. Many of the 
Company's competitors are larger and have substantially greater financial and 
other resources than the Company. See "Business -- Competition". 

LIMITED OPERATING HISTORY 

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

DEPENDENCE ON KEY PERSONNEL 

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

                               13           
<PAGE>
   
highly qualified management and technical personnel. Messrs. Lanza and 
LaPenta invested approximately $18 million to purchase 16.6% of the initial 
capital stock of Holdings. Holdings has entered into employment agreements 
with Messrs. Lanza and LaPenta. See "Management -- Employment Agreements". 
The Company maintains key man life insurance to cover Messrs. Lanza and 
LaPenta. The Company also faces competition for management and technical 
personnel from other companies and organizations. There can be no assurance 
that the Company will continue to be successful in hiring and retaining key 
personnel. See "Management -- Directors and Executive Officers". 
    

ENVIRONMENTAL LIABILITIES 

   The Company's operations are subject to various federal, state and local 
environmental laws and regulations relating to the discharge, storage, 
treatment, handling, disposal and remediation of certain materials, 
substances and wastes used in its operations. The Company continually 
assesses its obligations and compliance with respect to these requirements. 
Management believes that the Company's current operations are in substantial 
compliance with all applicable environmental laws and permits. The Company 
does not believe that its environmental compliance expenditures will have a 
material adverse effect on its financial condition or the results of its 
operations. 

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

BACKLOG 

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

OWNERSHIP OF HOLDINGS AND L-3 COMMUNICATIONS 

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

                               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. 

SUBORDINATION 

   
   Obligations of L-3 Communications and the Guarantors under the Notes and 
the Guarantees, respectively, are subordinate and junior in right of payment 
to all existing and future Senior Debt of L-3 Communications and the 
Guarantors, respectively. As of December 31, 1997, on a pro forma basis after 
giving effect to the L-3 Acquisition, the 1998 Acquisitions and the 
Offerings, L-3 Communications would have had approximately $433.6 million of 
indebtedness outstanding, of which $58.6 million would have been Senior Debt 
(excluding letters of credit) all of which would have been guaranteed by the 
Guarantors on a senior basis. Additional Senior Debt may be incurred by L-3 
Communications from time to time, subject to certain restrictions. By reason 
of such subordination, in the event of an insolvency, liquidation, or other 
reorganization of L-3 Communications or the Guarantors, the lenders under the 
Senior Credit Facilities and other creditors who are holders of Senior Debt 
must be paid in full before the holders of the Notes and the Guarantees may 
be paid; accordingly, there may be insufficient assets remaining after 
payment of prior claims to pay amounts due on the Notes or the Guarantees. In 
addition, under certain circumstances, no payments may be made with respect 
to the Notes or the Guarantees if a default exists with respect to certain 
Senior Debt. The Notes and the Guarantees rank on a parity or pari passu with 
the L-3 Communications' 10 3/8% Senior Subordinated Notes due 2007 and the 
guarantees thereof. See "Description of the Notes -- Subordination". 
    

RESTRICTIONS IMPOSED BY THE SENIOR CREDIT FACILITIES AND THE INDENTURES 

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

                               15           
<PAGE>
   
ratios, including total EBITDA to total interest expense and total debt to 
total EBITDA, and limit capital expenditures by L-3 Communications. The 
ability of L-3 Communications to comply with such ratios and limits may be 
affected by events beyond L-3 Communications' control. A breach of any of 
these covenants or the inability of L-3 Communications to comply with the 
required financial ratios or limits could result in a default under the 
Senior Credit Facilities. In the event of any such default, the lenders under 
the Senior Credit Facilities could elect to declare all borrowings 
outstanding under the Senior Credit Facilities, together with accrued 
interest and other fees, to be due and payable, to require L-3 Communications 
to apply all of its available cash to repay such borrowings or to prevent L-3 
Communications from making debt service payments on other indebtedness 
(including the 1997 Notes), any of which would be an Event of Default under 
the Notes. If L-3 Communications were unable to repay any such borrowings 
when due, the lenders could proceed against their collateral. In connection 
with the Senior Credit Facilities, L-3 Communications has granted the lenders 
thereunder a first priority lien on substantially all of its assets. The 
lenders under the Senior Credit Facilities will also have a first priority 
security interest in all of the capital stock of L-3 Communications and its 
subsidiaries. If the indebtedness under the Senior Credit Facilities, the 
1997 Notes or the Notes were to be accelerated, there can be no assurance 
that the assets of L-3 Communications would be sufficient to repay such 
indebtedness in full. See "Description of the Notes" and "Description of 
Certain Indebtedness". 
    

FRAUDULENT CONVEYANCE 

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

LIMITATION ON CHANGE OF CONTROL 

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

                               16           
<PAGE>
   
provisions. In the event a Change of Control event occurs at a time when L-3 
Communications is prohibited from purchasing the Notes or the 1997 Notes, or 
if L-3 Communications is required to make a Net Proceeds Offer (as defined 
under "Description of the Notes") pursuant to the terms of the Notes or the 
1997 Notes, L-3 Communications could seek the consent of its lenders to the 
purchase of the Notes or the 1997 Notes or could attempt to refinance the 
borrowings that contain such prohibition. If L-3 Communications does not 
obtain such a consent or repay such borrowings, L-3 Communications will 
remain prohibited from purchasing the Notes or the 1997 Notes. In such case, 
L-3 Communications' failure to make such an offer or to purchase tendered 
Notes or the 1997 Notes would constitute an Event of Default under the 
Indenture or the 1997 Indenture. If, as a result thereof, a default occurs 
with respect to any Senior Debt, the subordination provisions in the 
Indenture would likely restrict payments to the holders of the Notes. 
Finally, L-3 Communications' ability to pay cash to the holders of Notes or 
the 1997 Notes upon a purchase may be limited by L-3 Communications' 
then-existing financial resources. There can be no assurance that sufficient 
funds will be available when necessary to make any required purchases. 
Furthermore, the Change of Control provisions may in certain circumstances 
make more difficult or discourage a takeover of the Company. See "Description 
of the Notes --Repurchase at the Option of Holders -- Change of Control". 
    

LACK OF MARKET FOR THE NOTES 

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

FORWARD LOOKING STATEMENTS 

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

                               USE OF PROCEEDS 

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

   
   The Company intends to use the net proceeds of the Notes Offering, 
together with the net proceeds of the Common Stock Offering contributed to 
L-3 Communications, to repay a substantial portion of its existing 
indebtedness under the Senior Credit Facilities and for general corporate 
purposes, including potential acquisitions. The borrowings under the Senior 
Credit Facilities had been used by the Company to fund in part the L-3 
Acquisition and the 1998 Acquisitions. The weighted average interest rate 
under the Term Loan Facilities was 7.99% at February 24, 1998. Amounts repaid 
under the Revolving Credit Facility will be available to be reborrowed by the 
Company from time to time for, among other reasons, general corporate 
purposes or to finance future acquisitions. Affiliates of the Underwriters 
are lenders under the Senior Credit Facilities and will receive a portion of 
the net proceeds of the Offerings in repayment of amounts outstanding 
thereunder. See "Description of Certain Indebtedness -- Senior Credit 
Facilities".

       UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION 

   
   The following unaudited pro forma financial information gives effect to 
the L-3 Acquisition, the 1998 Acquisitions and the Offerings (collectively, 
the "Transactions"). The Offerings include the Notes Offering and the 
contribution by Holdings to the Company of the proceeds of the Common Stock 
Offering. The unaudited pro forma condensed consolidated statement of 
operations gives effect to the Transactions as if they had occurred as of 
January 1, 1997. The unaudited pro forma condensed consolidated balance sheet 
gives effect to the Transactions as if they had occurred as of December 31, 
1997. The pro forma financial information is based on (i) the consolidated 
financial statements of the Company for the nine-month period ended December 
31, 1997, (ii) the Combined Statement of Operations of the Predecessor 
Company for the three-month period ended March 31, 1997 and (iii) 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 price. 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 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, (ii) the audited financial statements of STS for the year 
ended June 30, 1997, (iii) the unaudited condensed financial statements of 
STS as of December 31, 1997 and for the six months ended December 31, 1997 
and 1996, (iv) the audited consolidated financial statements of ILEX as of 
December 31, 1997 and for the year ended December 31, 1997 and (v) 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 
   effective cost of borrowing rates incurred by the Company to finance the 
   L-3 Acquisition less interest expense of approximately $8.5 million 
   included in the historical financial statements of the Predecessor 
   Company. 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 purchase prices are subject to adjustment based upon the actual 
   closing net assets of STS and ILEX as defined. For purposes of the pro 
   forma financial information, the aggregate purchase prices (including 
   estimated expenses of $2.6 million) for the 1998 Acquisitions of $146.3 
   million were assumed to be financed using cash on hand of $77.5 million 
   and initially using $68.8 million of borrowings under the Revolving Credit 
   Facility. See Note 5 for the pro forma effects of the Offerings on 
   interest expense and long-term debt including the Revolving Credit 
   Facility.

4. The aggregate estimated excess of purchase price over fair value of net 
   assets acquired related to the 1998 Acquisitions is $89.0 million, 
   comprised of $37.2 million and $51.8 million, respectively, for ILEX and 
   Ocean Systems and is being amortized over 40 years resulting in a pro 
   forma charge of $2.2 million per annum. Based upon preliminary estimates of 
   fair value, the acquisition of STS resulted in no goodwill being recorded 
   since the purchase price was equal to the net assets acquired. The pro 
   forma balance sheet includes a net increase to costs in excess of 
   net assets acquired of $86.8 million after eliminating acquired cost in 
   excess of net assets acquired of $2.2 million included in the 1998 
   Acquisitions historical financial statements. 

   Other adjustments to the pro forma balance sheet include reductions to 
   cash of $82.4 million representing the use of $77.5 million of the 
   Company's historical cash and $2.7 million of acquired cash assumed to 
   have been used to fund partially the 1998 Acquisitions and the elimination 
   of $2.2 million of cash and other current liabilities included in the 1998 
   ILEX historical financial statements to reflect the assumed settlement of 
   distributions payable to the ILEX shareholders. Contracts-in-process pro 
   forma adjustments include a net reduction of $2.5 million to reflect $1.0 
   million of accounts receivable not acquired relating to ILEX, an inventory 
   write-up to fair value of $3.5 million primarily related to finished goods 
   at Ocean Systems and a reduction of $5.0 million relating to the valuation 
   of acquired contracts-in-process at contract price, less the estimated 
   cost to complete and an allowance for normal profit margin on the 
   Company's effort to complete such contracts. The pro forma balance sheet 
   includes a reduction to fixed assets of $3.4 million to eliminate net book 
   value of the Ocean Systems Sylmar facility which will not be acquired by 
   L-3 Communications. The fair value of other fixed assets is not expected 
   to differ materially from their historical carrying amounts. The pro forma 
   statement of operations does not reflect any adjustments related to the 
   inventory write-up and the valuation of acquired contracts-in-process 
   since such adjustments are neither recurring nor material.

   of interest income included in the historical financial statements of the 
   Company to reflect the use of cash on hand to fund partially the purchase 
   price for the 1998 Acquisitions and (b) an increase to interest expense of 
   $5.2 million on debt incurred to fund the remaining purchase prices for 
   the 1998 Acquisitions. Pro forma adjustments for the Offerings reflect a 
   decrease to interest expense of $1.9 million to reflect the reduction in 
   debt from the use of proceeds. The details of interest expense, after such 
   pro forma adjustments follow:

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

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

GENERAL 

   
   The Company is a leading merchant supplier of sophisticated secure 
communication systems and specialized communication products including 
secure, high data rate communication systems, microwave components, avionics 
and ocean systems, telemetry, instrumentation and space products. These 
systems and products are critical elements of virtually all major 
communication, command and control, intelligence gathering and space systems. 
The Company's systems and specialized products are used to connect a variety 
of airborne, space, groundand 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". 

                               27

RESULTS OF OPERATIONS 

   The following information should be read in conjunction with Consolidated 
(Combined) Financial Statements and the notes thereto. 

   
   The Company's financial statements reflect operations since the effective 
date of the L-3 Acquisition, April 1, 1997; and the Predecessor Company's 
results of operations for the three months ended March 31, 1997 and the year 
ended December 31, 1996 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 to 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 acquisitions. See Note 4 to the Consolidated (Combined) 
Financial Statements. The results of operations for the year ended December 
31, 1995 and the period from January 1 to March 31, 1996 represent the 
results of the Predecessor Company, which 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 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 acquisitions. Interest expense and 
income taxes expense for the periods are 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, 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 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 presented below exclude the results of 
operations of the 1998 Acquisitions for the year ended December 31, 1997. 

   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.

</TABLE>

 YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996 

   
   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 nil, 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), 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 
acquired, which were not deductible for income tax purposes. See Note 11 to 
Consolidated (Combined) Financial Statements.

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.

</TABLE>

   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 $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 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 management believes it to be a 
useful indicator of the Company's ability to meet debt service and capital 
expenditure requirements. EBITDA for the 1997 period increased by $9.2 
million to $93.8 million from $84.6 million from the 1996 period. EBITDA 
margin, defined as EBITDA as a percentage of sales, 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. 

 YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 

   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. 

   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 
    

                               31           
<PAGE>
   
and Senior Management and a $45.0 million retained interest in Holdings by 
Lockheed Martin representing partial consideration to Lockheed Martin for the 
L-3 Acquisition. In connection with its sale of the Businesses to the Company,
 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, 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 and the 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. 

                               32           
<PAGE>
   
   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 to interest 
expense was not material for the nine months ended December 31, 1997. See 
Note 10 to the Consolidated (Combined) Financial Statements.

</TABLE>

   NET CASH PROVIDED BY (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 

                               33           
<PAGE>
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 PROVIDED BY 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. 

   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. 

 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 has financed the 1998 Acquisitions using its cash on hand and 
available borrowings under its 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. 

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 13 to the Consolidated (Combined) Financial Statements. 

RECENT ACCOUNTING PRONOUNCEMENTS 

   In June 1997, the Financial Accounting Standards Board ("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 a full set general purpose financial 
statements. 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 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. 130, 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 update 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.

   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 

                               40           
<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 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.

<PAGE>
     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, 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 vertically enhance its product base through internal research and 
    development efforts as well as selective acquisitions and horizontally add 
    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 
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 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. 
    

 Satellite Transmission Systems 

   
   On February 5, 1998, L-3 Communications purchased the assets of 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, 
    

                               42

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, telecommunication 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, 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, 
purchased by Lockheed Martin as part of its acquisition of GE Aerospace in 
April 1993 (collectively, the "Businesses"). L-3 Communications is a

<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")

"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.

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

   Narda West designs and manufactures state-of-the-art space-qualified and 
wireless components. Space qualified components include channel amplifiers 
for satellite transponder control and diplexers/ multiplexers, which are used 
to separate various signals and direct them to the appropriate other sections 
of the payload. Narda West's primary areas of focus are communications 
satellite payload products. Channel amplifiers constitute Narda West's main 
satellite product. These components amplify the weak signals received from 
earth stations by a factor of 1 million, and then drive the power amplifier 
tubes that broadcast the signal back to earth. These products are sold to 
satellite manufacturers and offer lower cost, lower weight and improved 
performance versus in-house alternatives. On a typical satellite, for which 
there are 20 to 50 channel amps, Narda West's channel amps offer cost savings 
of up to 60% (up to $1 million per satellite) and decrease launch weight by 
up to 25 kilograms. 

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

AVIONICS AND OCEAN SYSTEMS 

O  AVIATION RECORDERS 

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

O  ANTENNA SYSTEMS 

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

                               46           
<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 

                               47           
<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.

   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 

                               48           
<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 

                               49           
<PAGE>
generally license it to use patents owned by others. Similar provisions in 
the Government contracts awarded to other companies make it impossible for 
the Company to prevent the use by other companies of its patents in most 
domestic work. 

BACKLOG 

   As of December 31, 1997, the Company's pro forma funded backlog was 
approximately $638.1 million. This backlog provides management with a useful 
tool to project sales and plan its business on an on-going basis; however, no 
assurance can be given that the Company's backlog will become revenues in any 
particular period or at all. Funded backlog does not include the total 
contract value of multi-year, cost-plus reimbursable contracts, which are 
funded as costs are incurred by the Company. Funded backlog also does not 
include unexercised contract options which represent the amount of revenue 
which would be recognized from the performance of contract options that may 
be exercised by customers under existing contracts and from purchase orders 
to be issued under indefinite quantity contracts or basic ordering 
agreements. Backlog is a more relevant predictor of future sales in the 
Secure Communication Systems business area. Current funded backlog in Secure 
Communication Systems as of December 31, 1997 was $306.0 million, of which 
approximately 93% is expected to be shipped in 1998. The Company believes 
backlog is a less relevant factor in the Specialized Communication Products 
business area given the nature of its catalog and commercial oriented 
business. Overall, approximately 85% of the Company's December 31, 1997 
funded backlog is expected to be shipped in 1998.

</TABLE>

GOVERNMENT CONTRACTS 

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

   Approximately 64% of the Company's pro forma 1997 sales mix of contracts 
were firm fixed price contracts under which the Company agrees to perform for 
a predetermined price. Although the Company's fixed price contracts generally 
permit the Company to keep profits if costs are less than projected, the 
Company does bear the risk that increased or unexpected costs may reduce 
profit or cause the Company to sustain losses on the contract. Generally, 
firm fixed price contracts offer higher margin than cost plus type contracts. 
All domestic defense contracts and subcontracts to which the Company is a 
party are subject to audit, various profit and cost controls and standard 
provisions for termination at the convenience of the Government. Upon 
termination, other than for a contractor's default, the contractor will 
normally be entitled to reimbursement for allowable costs and to an allowance 
for profit. Foreign defense contracts generally contain comparable provisions 
relating to termination at the convenience of the government. To date, no 
significant fixed price contract of the Company has been terminated. 

   Companies supplying defense-related equipment to the Government are 
subject to certain additional business risks peculiar to that industry. Among 
these risks are the ability of the Government to unilaterally suspend the 
Company from new contracts pending resolution of alleged violations of 
procurement laws or regulations. Other risks include a dependence on 
appropriations by the Government, changes in the Government's procurement 
policies (such as greater emphasis on competitive procurements) and the need 
to bid on programs in advance of design completion. A reduction in 
expenditures by the Government for products of the type manufactured by the 
Company, lower margins resulting from increasingly competitive procurement 
policies, a reduction in the volume of contracts or subcontracts awarded to 
the Company or substantial cost overruns would have an adverse effect on the 
Company's cash flow.

LEGAL PROCEEDINGS 

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

                               51           
<PAGE>
ENVIRONMENTAL MATTERS 

   
   The Company's operations are subject to various federal, state and local 
environmental laws and regulations relating to the discharge, storage, 
treatment, handling, disposal and remediation of certain materials, 
substances and wastes used in its operations. The Company continually 
assesses its obligations and compliance with respect to these requirements. 
Management believes that the Company's current operations are in substantial 
compliance with all existing applicable environmental laws and permits. The 
Company does not believe that its environmental compliance expenditures will 
have a material adverse effect on its financial condition or results of its 
operations. 
    

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

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

PENSION PLANS 

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

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

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

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

EMPLOYEES 

   
   As of December 31, 1997, the Company employed approximately 6,100 
full-time and part-time employees. The Company believes that its relations 
with its employees are good. 
    

   Approximately 540 of the Company's employees at its Communication Systems 
- -- East operation in Camden, New Jersey are represented by four unions, the 
Association of Scientists and Professional Engineering Personnel, the 
International Federation of Professional and Technical Engineers, the 
International Union of Electronic, Electrical, Salaried, Machine and 
Furniture Workers and an affiliate of the International Brotherhood of 
Teamsters. Three of the four collective bargaining agreements expire in 
mid-1998. While the Company has not yet initiated discussions with 
representatives of these unions, management believes it will be able to 
negotiate, without material disruption to its business, satisfactory new 
collective bargaining agreements with these employees. However, there can be 
no assurance that a satisfactory agreement will be reached with the covered 
employees or that a material disruption to the Company's Camden operations 
will not occur. 

   Approximately 200 employees of Ocean Systems are represented by the United 
Auto Workers. The collective bargaining agreement expires in mid-1999. 
Approximately 140 of the employees at Ocean Systems' ELAC subsidiary in Kiel, 
Germany are represented by the Metal Trade Industrial Workers of the Hamburg 
Region and ELAC is represented by the Association of Metal Industry Employers 
for Schleswig-Holstein. The labor contract expires in mid-1998. While the 
Company has not yet initiated discussions with representatives of these 
unions, management believes it will be able to negotiate, without material 
disruption to its business, a satisfactory new labor contract with these 
employees. However, there can be no assurance that a satisfactory agreement 
will be reached with the covered employees or that material disruption to 
operations of ELAC or Ocean Systems will not occur.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS 

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

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

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

   In the ordinary course of business L-3 sells products to Lockheed Martin 
and its affiliates. Pro forma and aggregated sales to Lockheed Martin were 
$81.6 million, $70.7 million and $25.9 million for the years ended December 
31, 1997, 1996 and 1995, respectively. See Note 19 to the Consolidated 
(Combined) Financial Statements. 

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

STOCKHOLDERS AGREEMENT 

   Holdings, Lockheed Martin, the Lehman Partnership and Messrs. Lanza and 
LaPenta entered into a stockholders agreement (the "Stockholders Agreement") 
which, except the terms relating to (i) the registration rights, (ii) 
provision of services by Lehman Brothers Inc. and (iii) the standstill 
agreement by Lockheed Martin, terminates upon the consummation of the Common 
Stock Offering. Prior to the consummation of the Common Stock Offering, the 
Lehman Partnership is entitled to designate a majority of the members of the 
Board of Directors provided that it holds at least 35% of the capital stock 
of Holdings and remains the single largest shareholder. 

   Pursuant to the Stockholders Agreement, certain of the existing 
stockholders have the right, from time to time on or after the 180-day period 
following the completion of the initial public offering and subject to 
certain conditions, to require the Company to register under the Securities 
Act shares of Common Stock held by them. Lockheed Martin, the Lehman 
Partnership and each of the Senior Management has three, four and one demand 
registration rights, respectively. In addition, the Stockholders 

                               54           
<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). 
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%.

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

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

COMMITTEES OF THE BOARD OF DIRECTORS 

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

COMPENSATION OF DIRECTORS 

   The current directors of the Company do not receive compensation for their 
services as directors. Any non-affiliated directors will receive directors' 
fees and reimbursements for their reasonable out-of-pocket expenses in 
connection with their travel to and attendance at meetings of the board of 
directors or committees thereof. 

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS 

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

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

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

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION 

   The Board of Directors of Holdings established a Compensation Committee in 
June 1997. During the last fiscal year, Messrs. Robert Millard, Steven Berger 
and John Montague served as members of the Compensation Committee. None of 
these individuals has served at any time as an officer or employee of 
Holdings or L-3 Communications. Mr. Berger resigned from Holdings' Board of 
Directors and the Compensation Committee in January 1998. Prior to the 
establishment of the Compensation Committee, all decisions relating to 
executive compensation were made by Holdings' Board of Directors. For a 
description of the transactions between the Company and entities affiliated 
with members of the Compensation Committee, see "Certain Relationships and 
Certain Transactions". 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
   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 228,571 options.
    

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 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' 

                               62           
<PAGE>
   
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 

   
   All outstanding capital stock of L-3 Communications is owned by Holdings. 
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.

       partnerships. Such individuals disclaim any such beneficial ownership. 

                     DESCRIPTION OF CERTAIN INDEBTEDNESS 

SENIOR CREDIT FACILITIES 

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

   All borrowings under the Senior Credit Facilities bear interest, at L-3 
Communications' option, at either: (A) a "base rate" equal to, for any day, 
the higher of: (a) 0.50% per annum above the latest Federal Funds Rate; and 
(b) the rate of interest in effect for such day as publicly announced from 
time to time 

                               64

by Bank of America NT&SA, as Administrative Agent, in San Francisco, 
California, as its "reference rate" plus (i) in the case of the Tranche A 
Term Loan, the Revolving Credit Facility and the Swingline Loans, a debt to 
EBITDA-dependent rate ranging from 0.50% to 1.25% per annum, (ii) in the case 
of the Tranche B Term Loan, a rate of 1.50% per annum or (iii) in the case of 
the Tranche C Term Loan, a rate of 1.75% per annum or (B) a "LIBOR rate" 
equal to, for any Interest Period (as defined in the Senior Credit 
Facilities), with respect to LIBOR Loans comprising part of the same 
borrowing, the London interbank offered rate of interest per annum for such 
Interest Period as determined by the Administrative Agent, plus (i) in the 
case of the Tranche A Term Loan and the Revolving Credit Facility, a debt to 
EBITDA-dependent rate ranging from 1.50% to 2.25% per annum, (ii) in the case 
of the Tranche B Term Loan, a rate of 2.50% per annum or (iii) in the case of 
the Tranche C Term Loan, a rate of 2.75% per annum. 

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

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

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

   The Term Loans are subject to the following amortization schedule:

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

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

10 3/8% SENIOR SUBORDINATED NOTES DUE 2007 

   L-3 Communications has outstanding $225.0 million in aggregate principal 
amount of its 10 3/8% Senior Subordinated Notes due 2007 (the "1997 Notes"). 
The 1997 Notes are subject to the terms and conditions of an Indenture (the 
"1997 Indenture") dated as of April 30, 1997 between L-3 Communications and 
The Bank of New York, as trustee, a copy of which was filed as an exhibit to 
L-3 Communications' Registration Statement on Form S-4 relating to the 1997 
Notes. The 1997 Notes are subject to all of the terms and conditions of the 
1997 Indenture. The following summary of the material provisions of the 1997 
Indenture does not purport to be complete, and is subject to, and qualified 
in its entirety by reference to, all of the provisions of the 1997 Indenture 
and those terms made a part of the 1997 Indenture by the Trust Indenture Act 
of 1939, as amended. All terms defined in the 1997 Indenture and not 
otherwise defined herein are used below with the meanings set forth in the 
1997 Indenture. 

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

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

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

   Change of Control. Upon the occurrence of a Change of Control, each holder 
of the 1997 Notes may require L-3 Communications to repurchase all or a 
portion of such holder's 1997 Notes at a purchase price equal to 101% of the 
principal amount thereof (plus accrued and unpaid interest). Generally, a 
Change of Control means the occurrence of any of the following: (i) the 
disposition of all or substantially all of L-3 Communications' assets to any 
person, (ii) the adoption of a plan relating to the liquidation or 
dissolution of L-3 Communications, (iii) the consummation of any transaction 
in which a person other than the Principals and their Related Parties becomes 
the beneficial owner of more than 50% of the voting stock of L-3 
Communications, or (iv) the first day on which a majority of the members of 
the Board of Directors of L-3 Communications are not Continuing Directors. 

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

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

   Events of Default. Events of Default under the 1997 Indenture include the 
following: (i) a default for 30 days in the payment when due of interest on 
the 1997 Notes; (ii) default in payment when due of 

                               66           
<PAGE>
the principal of or premium, if any, on the Notes; (iii) failure by L-3 
Communications to comply with certain provisions of the 1997 Indenture 
(subject, in some but not all cases, to notice and cure periods); (iv) 
default under Indebtedness for money borrowed by L-3 Communications or any of 
its Restricted Subsidiaries in excess of $10.0 million; (v) failure by L-3 
Communications or any Restricted Subsidiary that would be a Significant 
Subsidiary to pay final judgments aggregating in excess of $10.0 million, 
which judgments are not paid, discharged or stayed for a period of 60 days; 
(vi) except as permitted by the Indenture, any Subsidiary Guarantee shall be 
held in any judicial proceeding to be unenforceable or invalid or shall cease 
for any reason to be in full force and effect or any Guarantor, or any Person 
acting on behalf of any Guarantor, shall deny or disaffirm its obligations 
under its Subsidiary Guarantee; or (vii) certain events of bankruptcy or 
insolvency with respect to L-3 Communications or any of its Restricted 
Subsidiaries. 

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

                           DESCRIPTION OF THE NOTES 

GENERAL 

   The Notes will be issued under an indenture dated as of       , 1998 (the 
"Indenture") between the Company, as issuer, and                       , as 
trustee (the "Trustee"). The terms of the Notes include those stated in the 
Indenture and those made part of the Indenture by reference to the Trust 
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The Notes are 
subject to all such terms, and holders of the Notes are referred to the 
Indenture and the Trust Indenture Act for a statement thereof. The following 
summary of the material provisions of the Indenture describes the material 
terms of the Indenture but does not purport to be complete and is subject to, 
and qualified in its entirety by reference to, the provisions of the 
Indenture, including the definitions of certain terms contained therein and 
those terms made part of the Indenture by reference to the Trust Indenture 
Act. For definitions of certain capitalized terms used in the following 
summary, see "--Certain Definitions". 

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

   The Notes will be general unsecured obligations of the Company and will 
rank pari passu in right of payment with the 1997 Notes and will be 
subordinated in right of payment to all current and future Senior Debt. At 
December 31, 1997, on a pro forma basis giving effect to the 1998 
Acquisitions and the Offerings, the Company would have had Senior Debt of 
approximately $58.6 million outstanding (excluding letters of credit). The 
Indenture will permit the incurrence of additional Senior Debt in the future. 
See "--Certain Covenants -- Incurrence of Indebtedness and Issuance of 
Preferred Stock". 

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

PRINCIPAL, MATURITY AND INTEREST 

   The Notes will be limited in aggregate principal amount to $250.0 million, 
of which $150.0 million will be issued in the Notes Offering. The Notes will 
mature on       , 2008. Interest on the Notes will accrue at the rate of    % 
per annum and will be payable semi-annually in arrears on        and       , 
commencing on       , 1998, to Holders of record on the immediately preceding 
     and      . Interest on the Notes will accrue from the most recent date 
to which interest has been paid or, if no interest has been paid, from the 
date of original issuance. Interest will be computed on the basis of a 
360-day year comprised of twelve 30-day months. Principal, premium, if any, 
and interest on the Notes will be payable at the office or agency of the 
Company maintained for such purpose within the City and State of New York or, 
at the option of the Company, payment of interest may be made by check mailed 
to the Holders of the Notes at their respective addresses set forth in the 
register of Holders of Notes; provided that all payments of principal, 
premium and interest with respect to Notes the Holders of which have given 
wire transfer instructions to the Company will be required to be made by wire 
transfer of immediately available funds to the accounts specified by the 
Holders thereof if such Holders shall be registered Holders of at least 
$250,000 in principal amount of Notes. Until otherwise designated by the 
Company, the Company's office or agency in New York will be the office of the 
Trustee maintained for such purpose. The Notes will be issued in 
denominations of $1,000 and integral multiples thereof. 

OPTIONAL REDEMPTION 

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

                               68           
<PAGE>
of principal amount) set forth below plus accrued and unpaid interest to the 
applicable redemption date, if redeemed during the twelve-month period 
beginning on        of the years indicated below: 

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

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

SUBORDINATION 

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

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

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

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

                               69           
<PAGE>
   As a result of the subordination provisions described above, in the event 
of a liquidation or insolvency, Holders of Notes may recover less ratably 
than creditors of the Company who are holders of Senior Debt. On a pro forma 
basis, after giving effect to the Offerings and the 1998 Acquisitions, the 
principal amount of Senior Debt outstanding (excluding letters of credit) at 
December 31, 1997 would have been approximately $58.6 million. 

SELECTION AND NOTICE 

   If less than all of the Notes are to be redeemed at any time, selection of 
Notes for redemption will be made by the Trustee in compliance with the 
requirements of the principal national securities exchange, if any, on which 
the Notes are listed, or, if the Notes are not so listed, on a pro rata 
basis, by lot or by such method as the Trustee shall deem fair and 
appropriate; provided that no Notes of $1,000 or less shall be redeemed in 
part. Notices of redemption shall be mailed by first class mail at least 30 
but not more than 60 days before the redemption date to each Holder of Notes 
to be redeemed at its registered address. Notices of redemption may not be 
conditional. If any Note is to be redeemed in part only, the notice of 
redemption that relates to such Note shall state the portion of the principal 
amount thereof to be redeemed. A new Note in principal amount equal to the 
unredeemed portion thereof will be issued in the name of the Holder thereof 
upon cancellation of the original Note. Notes called for redemption become 
due on the date fixed for redemption. On and after the redemption date, 
interest ceases to accrue on Notes or portions of them called for redemption. 

MANDATORY REDEMPTION 

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

REPURCHASE AT THE OPTION OF HOLDERS 

 CHANGE OF CONTROL 

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

   On the Change of Control Payment Date, the Company will, to the extent 
lawful, (i) accept for payment all Notes or portions thereof properly 
tendered pursuant to the Change of Control Offer, (ii) deposit with the 
Paying Agent an amount equal to the Change of Control Payment in respect of 
all Notes or portions thereof so tendered and (iii) deliver or cause to be 
delivered to the Trustee the Notes so accepted together with an Officers' 
Certificate stating the aggregate principal amount of Notes or portions 
thereof being purchased by the Company. The Paying Agent will promptly mail 
to each Holder of Notes so tendered the Change of Control Payment for such 
Notes, and the Trustee will promptly authenticate and mail (or cause to be 
transferred by book entry) to each Holder a new Note equal in principal 
amount to any unpurchased portion of the Notes surrendered, if any; provided 
that each such new Note will be in a principal amount of $1,000 or an 
integral multiple thereof. 

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

                               70           
<PAGE>
offer or obtain the requisite consents, if any, under all agreements 
governing outstanding Senior Debt to permit the repurchase of Notes required 
by this covenant. The Company will publicly announce the results of the 
Change of Control Offer on or as soon as practicable after the Change of 
Control Payment Date. 

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

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

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

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

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

                               71           
<PAGE>
   "Principals" means any Lehman Investor, Lockheed Martin Corporation, Frank 
C. Lanza and Robert V. LaPenta. 

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

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

   With respect to the disposition of assets, the phrase "all or 
substantially all" as used in the Indenture varies according to the facts and 
circumstances of the subject transaction and is subject to judicial 
interpretation. Accordingly, in certain circumstances there may be a degree 
of uncertainty in ascertaining whether a particular transaction would involve 
a disposition of "all or substantially all" of the assets of the Company, and 
therefore it may be unclear as to whether a Change of Control has occurred 
and whether the holders have the right to require the Company to purchase the 
Notes. 
    

 ASSET SALES 

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

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

                               72           
<PAGE>
with the procedures set forth in the Indenture. To the extent that the 
aggregate amount of Notes or pari passu Indebtedness tendered pursuant to a 
Secondary Asset Sale Offer is less than the Remaining Excess Proceeds, the 
Company may use any Remaining Excess Proceeds for general corporate purposes. 
If the aggregate principal amount of Notes or pari passu Indebtedness 
surrendered by Holders thereof exceeds the amount of Remaining Excess 
Proceeds in a Secondary Asset Sale Offer, the Company shall repurchase such 
Indebtedness on a pro rata basis and the Trustee shall select the Notes to be 
purchased on a pro rata basis. Upon completion of such offer to purchase, the 
amount of Excess Proceeds shall be reset at zero. 

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

CERTAIN COVENANTS 

 RESTRICTED PAYMENTS 

   The Indenture will provide that the Company will not, and will not permit 
any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or 
pay any dividend or make any other payment or distribution on account of the 
Company's or any of its Restricted Subsidiaries' Equity Interests (including, 
without limitation, any payment in connection with any merger or 
consolidation involving the Company) or to the direct or indirect holders of 
the Company's or any of its Restricted Subsidiaries' Equity Interests in 
their capacity as such (other than (A) dividends or distributions payable in 
Equity Interests (other than Disqualified Stock) of the Company or (B) 
dividends or distributions by a Restricted Subsidiary so long as, in the case 
of any dividend or distribution payable on or in respect of any class or 
series of securities issued by a Restricted Subsidiary other than a Wholly 
Owned Restricted Subsidiary, the Company or a Restricted Subsidiary receives 
at least its pro rata share of such dividend or distribution in accordance 
with its Equity Interests in such class or series of securities); (ii) 
purchase, redeem or otherwise acquire or retire for value (including without 
limitation, in connection with any merger or consolidation involving the 
Company) any Equity Interests of the Company or any direct or indirect parent 
of the Company; (iii) make any payment on or with respect to, or purchase, 
redeem, defease or otherwise acquire or retire for value any Indebtedness 
that is subordinated to the Notes except a payment of interest or principal 
at Stated Maturity; or (iv) make any Restricted Investment (all such payments 
and other actions set forth in clauses (i) through (iv) above being 
collectively referred to as "Restricted Payments"), unless, at the time of 
and after giving effect to such Restricted Payment: 

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

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

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

                               73           
<PAGE>
    convertible debt securities) sold to a Subsidiary of the Company and other 
    than Disqualified Stock or convertible debt securities that have been 
    converted into Disqualified Stock), plus (iii) to the extent that any 
    Restricted Investment that was made after April 30, 1997 is sold for cash 
    or otherwise liquidated or repaid for cash, the amount of cash received in 
    connection therewith (or from the sale of Marketable Securities received 
    in connection therewith), plus (iv) to the extent not already included in 
    such Consolidated Net Income of the Company for such period and without 
    duplication, (A) 100% of the aggregate amount of cash received as a 
    dividend from an Unrestricted Subsidiary, (B) 100% of the cash received 
    upon the sale of Marketable Securities received as a dividend from an 
    Unrestricted Subsidiary, and (C) 100% of the net assets of any 
    Unrestricted Subsidiary on the date that it becomes a Restricted 
    Subsidiary. As of December 31, 1997 (without giving effect to the Common 
    Stock Offering), the amount that would have been available to the Company 
    for Restricted Payments pursuant to this paragraph (c) would have been 
    $6.8 million. 

   The foregoing provisions will not prohibit: 

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

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

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

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

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

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

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

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

                               74           
<PAGE>
paragraph of this covenant. All such outstanding Investments will be deemed 
to constitute Investments in an amount equal to the fair market value of such 
Investments at the time of such designation. Such designation will only be 
permitted if such Restricted Payment would be permitted at such time and if 
such Restricted Subsidiary otherwise meets the definition of an Unrestricted 
Subsidiary. 

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

 INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK 

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

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

     (i) the incurrence by the Company of Indebtedness under Credit Facilities 
    (and the guarantee thereof by the Guarantors); provided that the aggregate 
    principal amount of all Indebtedness outstanding under all Credit 
    Facilities (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) 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 $375.0 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 the 
    covenant described above under the caption "--Asset Sales"; 

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

     (iii) the incurrence by the Company and the Guarantors of $150.0 million 
    in aggregate principal amount of the Notes and the Subsidiary Guarantees 
    thereof; 

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

     (v) the incurrence by the Company or any of its Restricted Subsidiaries 
    of Indebtedness in connection with the acquisition of assets or a new 
    Restricted Subsidiary; provided that such Indebtedness was incurred by the 
    prior owner of such assets or such Restricted Subsidiary prior to 

                               75           
<PAGE>
    such acquisition by the Company or one of its Restricted Subsidiaries and 
    was not incurred in connection with, or in contemplation of, such 
    acquisition by the Company or one of its Restricted Subsidiaries; and 
    provided further that the principal amount (or accreted value, as 
    applicable) of such Indebtedness, together with any other outstanding 
    Indebtedness incurred pursuant to this clause (v), does not exceed $10.0 
    million; 

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

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

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

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

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

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

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

                               76           
<PAGE>
     (xiii) obligations in respect of performance and surety bonds and 
    completion guarantees provided by the Company or any Restricted 
    Subsidiaries in the ordinary course of business; and 

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

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

 LIENS 

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

 ANTILAYERING PROVISION 

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

 DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES 

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

 MERGER, CONSOLIDATION OR SALE OF ASSETS 

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

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

 TRANSACTIONS WITH AFFILIATES 

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

                               78           
<PAGE>
$5.0 million, a resolution of the Board of Directors set forth in an 
Officers' Certificate certifying that such Affiliate Transaction complies 
with clause (i) above and that such Affiliate Transaction has been approved 
by a majority of the disinterested members of the Board of Directors and (B) 
with respect to any Affiliate Transaction or series of related Affiliate 
Transactions involving aggregate consideration in excess of $15.0 million, an 
opinion as to the fairness to the Holders of such Affiliate Transaction from 
a financial point of view issued by an accounting, appraisal or investment 
banking firm of national standing. 

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

 PAYMENTS FOR CONSENT 

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

 REPORTS 

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

                               79           
<PAGE>
 FUTURE SUBSIDIARY GUARANTEES 

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

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

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

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

EVENTS OF DEFAULT AND REMEDIES 

   The Indenture will provide that each of the following constitutes an Event 
of Default: (i) default for 30 days in the payment when due of interest on 
the Notes (whether or not prohibited by the subordination provisions of the 
Indenture); (ii) default in payment when due of the principal of or premium, 
if any, on the Notes (whether or not prohibited by the subordination 
provisions of the Indenture); (iii) failure by the Company to comply with the 
provisions described under the captions "--Change of Control", "--Asset 
Sales" or "--Merger, Consolidation or Sale of Assets"; (iv) failure by the 
Company for 60 days after notice to comply with any of its other agreements 
in the Indenture or the Notes; (v) default under any mortgage, indenture or 
instrument under which there may be issued or by which there may be secured 
or evidenced any Indebtedness for money borrowed by the Company or any of its 
Restricted Subsidiaries (or the payment of which is guaranteed by the Company 
or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee 
now exists, or is created after the Issue Date, which default results in the 
acceleration of such Indebtedness prior to its express maturity and, in each 
case, the principal amount of 

                               80           
<PAGE>
any such Indebtedness, together with the principal amount of any other such 
Indebtedness the maturity of which has been so accelerated, aggregates $10.0 
million or more; (vi) failure by the Company or any of its Restricted 
Subsidiaries to pay final judgments aggregating in excess of $10.0 million, 
which judgments are not paid, discharged or stayed for a period of 60 days; 
(vii) certain events of bankruptcy or insolvency with respect to the Company 
or any of its Restricted Subsidiaries; and (viii) except as permitted by the 
Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding 
to be unenforceable or invalid. 

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

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

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

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

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS 

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

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

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

                               81           
<PAGE>
Notes and the maintenance of an office or agency for payment and money for 
security payments held in trust, (iii) the rights, powers, trusts, duties and 
immunities of the Trustee, and the Company's obligations in connection 
therewith and (iv) the Legal Defeasance provisions of the Indenture. In 
addition, the Company may, at its option and at any time, elect to have the 
obligations of the Company released with respect to certain covenants that 
are described in the Indenture ("Covenant Defeasance") and thereafter any 
omission to comply with such obligations shall not constitute a Default or 
Event of Default with respect to the Notes. In the event Covenant Defeasance 
occurs, certain events (not including non-payment, bankruptcy, receivership, 
rehabilitation and insolvency events) described under "Events of Default" 
will no longer constitute an Event of Default with respect to the Notes. 

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

TRANSFER AND EXCHANGE 

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

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

                               82           
<PAGE>
AMENDMENT, SUPPLEMENT AND WAIVER 

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

   Without the consent of each Holder affected, an amendment or waiver may 
not (with respect to any Notes held by a non-consenting Holder): (i) reduce 
the principal amount of Notes whose Holders must consent to an amendment, 
supplement or waiver, (ii) reduce the principal of or change the fixed 
maturity of any Note or alter the provisions with respect to the redemption 
of the Notes (other than provisions relating to the covenants described above 
under the caption "--Repurchase at the Option of Holders"), (iii) reduce the 
rate of or change the time for payment of interest on any Note, (iv) waive a 
Default or Event of Default in the payment of principal of or premium, if 
any, or interest on the Notes (except a rescission of acceleration of the 
Notes by the Holders of at least a majority in aggregate principal amount of 
the Notes and a waiver of the payment default that resulted from such 
acceleration), (v) make any Note payable in money other than that stated in 
the Notes, (vi) make any change in the provisions of the Indenture relating 
to waivers of past Defaults or the rights of Holders of Notes to receive 
payments of principal of or premium, if any, or interest on the Notes, (vii) 
waive a redemption payment with respect to any Note (other than a payment 
required by one of the covenants described above under the caption 
"--Repurchase at the Option of Holders") or (viii) make any change in the 
foregoing amendment and waiver provisions. In addition, any amendment to the 
provisions of Article 10 of the Indenture (which relates to subordination) 
will require the consent of the Holders of at least 75% in aggregate 
principal amount of the Notes then outstanding if such amendment would 
adversely affect the rights of Holders of Notes. 

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

CONCERNING THE TRUSTEE 

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

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

CERTAIN DEFINITIONS 

   Set forth below are certain defined terms used in the Indenture. Reference 
is made to the Indenture for a full disclosure of all such terms, as well as

                   UNITED STATES FEDERAL TAX CONSIDERATIONS 

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

STATED INTEREST ON NOTES 

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

SALE, EXCHANGE AND RETIREMENT OF NOTES 

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

NON-U.S. HOLDERS 

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

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

                               93           
<PAGE>
     (b) no withholding of U.S. federal income tax will be required with 
    respect to any gain or income realized by a Non-U.S. Holder upon the sale, 
    exchange, retirement or other disposition of a Note; and 

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

   To satisfy the requirement referred to in (a)(iv) above, the beneficial 
owner of such Note, or a financial institution holding the Note on behalf of 
such owner, must provide, in accordance with specified procedures, a paying 
agent of the Company with a statement to the effect that the beneficial owner 
is not a U.S. person. Currently, these requirements will be met if (i) the 
beneficial owner provides his name and address, and certifies, under 
penalties of perjury, that he is not a U.S. person (which certification may 
be made on an IRS Form W-8 (or successor form)) or (ii) a financial 
institution holding the Note on behalf of the beneficial owner certifies, 
under penalties of perjury, that such statement has been received by it and 
furnishes a paying agent with a copy thereof. Under recently finalized 
Treasury regulations (the "Final Regulations"), the statement requirement 
referred to in (a)(iv) above may also be satisfied with other documentary 
evidence for interest paid after December 31, 1998 with respect to an 
offshore account or through certain foreign intermediaries. 

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

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

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

INFORMATION REPORTING AND BACKUP WITHHOLDING 

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

                               94           
<PAGE>
   No information reporting or backup withholding will be required with 
respect to payments made by the Company or any paying agent to Non-U.S. 
Holders if a statement described in (a)(iv) under "--Non-U.S. Holders" has 
been received and the payor does not have actual knowledge that the 
beneficial owner is a U.S. person. 

   In addition, backup withholding and information reporting will not apply 
if payments on a Note are paid or collected by a foreign office of a 
custodian, nominee or other foreign agent on behalf of the beneficial owner 
of such Note, or if a foreign office of a broker (as defined in applicable 
Treasury regulations) pays the proceeds of the sale of a Note to the owner 
thereof. If, however, such nominee, custodian, agent or broker is, for U.S. 
federal income tax purposes, a U.S. person, a controlled foreign corporation 
or a foreign person that derives 50% or more of its gross income for certain 
periods from the conduct of a trade or business in the United States, or, for 
taxable years beginning after December 31, 1998, a foreign partnership, in 
which one or more U.S. persons, in the aggregate, own more than 50% of the 
income or capital interests in the partnership or which is engaged in a trade 
or business in the United States, such payments will be subject to 
information reporting (but not backup withholding), unless (i) such 
custodian, nominee, agent or broker has documentary evidence in its records 
that the beneficial owner is not a U.S. person and certain other conditions 
are met or (ii) the beneficial owner otherwise establishes an exemption. 
Under the Final Regulations, backup withholding will not apply to such 
payments absent actual knowledge that the payee is a U.S. person. 

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

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

   The underwriters named below (the "Underwriters") have severally agreed, 
subject to the terms and conditions of the underwriting agreement (the form 
of which has been filed as an exhibit to the Registration Statement of which 
this Prospectus is a part) (the "Underwriting Agreement"), to purchase from 
L-3 Communications, and L-3 Communications has agreed to sell to the 
Underwriters, the aggregate principal amount of Notes set forth opposite 
their respective names below.

</TABLE>

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

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

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

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

   Because Lehman Brothers Inc. is an "affiliate" of the Company under the 
Conduct Rules of the National Association of Securities Dealers, Inc. (the 
"NASD") and Lehman Brothers Commercial Paper Inc. and BancAmerica Robertson 
Stephens are lenders under the Senior Credit Facilities and may receive 
significant portions of the proceeds from the Offerings,           will act 
as "qualified independent underwriter". In accordance with the Conduct Rules 
of the NASD, the yield at which the Notes will be distributed to the public 
will be established at a yield no lower than that recommended by 
in its capacity as a qualified independent underwriter. 

   
   Bank of America NT&SA, an affiliate of BancAmerica Robertson Stephens, 
acts as the Administrative Agent and a lender under the Senior Credit 
Facilities. See "Description of Certain Indebtedness -- Senior Credit 
Facilities".

                        REPORT OF INDEPENDENT AUDITORS 

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

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

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

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

Board of Directors 
Lockheed Martin Corporation 

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

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

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

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

1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS 

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

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

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

2. CHANGE IN OWNERSHIP TRANSACTION 

   Holdings and L-3 were formed by Mr. Frank C. Lanza, the former President 
and Chief Operating Officer of Loral, Mr. Robert V. LaPenta, the former 
Senior Vice President and Controller of Loral (collectively, the "Equity 
Executives"), Lehman Brothers Capital Partners III, L.P. and its affiliates 
(the "Lehman Partnership") and Lockheed Martin to acquire the Businesses. The 
Company was capitalized with an equity contribution from Holdings of 
$125,000. 

   On March 28, 1997, Lanza, LaPenta, the Lehman Partnership, L-3, and 
Lockheed Martin entered into a Transaction Agreement (the "L-3 Acquisition 
Agreement") whereby Holdings would acquire the Businesses from Lockheed 
Martin (the "L-3 Acquisition"). Also included in the acquisition is a 
semiconductor product line of another business and certain leasehold 
improvements in New York City which were not material. Pursuant to the L-3 
Acquisition Agreement, L-3 acquired the Businesses from Lockheed Martin for 
$525,000, comprising $458,779 of cash, after a $21,221 reduction related to a 
purchase price adjustment, and $45,000 of common equity, representing a 34.9% 
interest in Holdings retained by Lockheed Martin, plus acquisition costs of 
$8,000. 

   The Company and Lockheed Martin finalized the purchase price adjustment 
pursuant to an amendment to the L-3 Acquisition Agreement dated November 5, 
1997, which also included the

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

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

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

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

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

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

   Had the L-3 Acquisition occurred on January 1, 1996, the unaudited pro 
forma sales and net income for the years ended December 31, 1997 and 1996 
would have been $703,600 and $16,300, and $663,200 and $9,700, respectively. 
The pro forma results, which are based on various assumptions, are not 
necessarily indicative of what would have occurred had the acquisition been 
consummated on January 1, 1996. The 1997 and 1996 pro forma sales and net 
income have been adjusted to (a) include the operations of the Loral Acquired 
Businesses from January 1, 1996 (Note 3) and (b) exclude the operations of 
the Hycor business net assets held for sale from January 1, 1996 (Note 6). 

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

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

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

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

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

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

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

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

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

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

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

   Intangibles of the Predecessor Company include costs allocated to the 
Businesses relating to the Request for Funding Authorization ("RFA"), 
consisting of over 20 restructuring projects to reduce operating costs, 
initiated by General Electric ("GE") Aerospace in 1990 and to the REC Advance 
Agreement ("RAA"), a restructuring plan initiated after Lockheed Martin's 
acquisition of GE Aerospace. The RAA was initiated to close two regional 
electronic manufacturing centers. Restructure costs are reimbursable from the 
U.S. Government if savings can be demonstrated to exceed costs. The total 
cost of restructuring under the RFA and the RAA represented approximately 15% 
of the estimated savings to the U.S. Government and, therefore, a deferred 
asset has been recorded by Lockheed Martin. The deferred asset is being 
allocated to all the former GE Aerospace sites, including the Communications 
Systems Division, on a basis that includes manufacturing labor, overhead, and 
direct material less non-hardware subcontracts. At December 31, 1997 and 
1996, approximately $2,313 and $4,400, respectively, of unamortized RFA and 
RAA costs are deferred on the Company's and the Predecessor Company's 
consolidated (combined) balance sheets in other current assets and other 
assets. 

   The carrying values of the Predecessor Company intangibles were reviewed 
if the facts and circumstances indicated potential impairment of their 
carrying value. If this review indicated that

 intangible assets were not recoverable, as determined based on the 
undiscounted cash flows of the entity acquired over the remaining 
amortization period, the Businesses carrying values related to the intangible 
asset were reduced by the estimated shortfall of cash flows. 

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

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

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

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

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

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

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

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

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

   Effective in December 1997 the Company adopted the provisions of SFAS No. 
129, "Disclosure of Information about Capital Structure" ("SFAS 129"). 

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

4. PREDECESSOR COMPANY ACQUISITION 

   Effective April 1, 1996, Lockheed Martin acquired substantially all the 
assets and liabilities of the defense businesses of Loral, including the 
Wideband Systems Division and the Products Group which are included in the 
Businesses. The acquisition of the Wideband Systems Division and Products 
Group businesses (the "Loral Acquired Businesses") has been accounted for as 
a purchase by Lockheed Martin Communications Systems -- Camden Division 
("Division"). The acquisition has been reflected in the financial statements 
based on the purchase price allocated to those acquired businesses by 
Lockheed Martin. The assets and liabilities recorded in connection with the 
purchase price allocation were $401,000 and $113,200, respectively. As such, 
the accompanying condensed combined financial statements for periods prior to 
April 1, 1997 reflect the results of operations of the Division and the Loral 
Acquired Businesses from the effective date of acquisition including the 
effects of an allocated portion of cost in excess of net assets acquired 
resulting from the acquisition.

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 $3.5 million 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.

   In connection with the L-3 Acquisition, the Company entered into a credit 
facility (the "Senior Credit Facilities") with a syndicate of banks and 
financial institutions for $275,000 consisting of $175,000 of term loans (the 
"Term Loan Facilities") and a $100,000 revolving credit facility (the 
"Revolving Credit Facility"). The Senior Credit Facilities bear interest, at 
the option of the Company, at a rate related to (i) the higher of federal 
funds rate plus 0.50% per annum or the reference rate published by Bank of 
America NT&SA or (ii) LIBOR. At December 31, 1997, such interest rates, based 
on various maturities, ranged from 7.625% to 8.625%. Interest payments vary 
in accordance with the type of borrowing and are made at a minimum every 
three months. The Revolving Credit Facility expires in 2003 and is available 
for ongoing working capital and letter of credit needs. The Term Loans mature 
in installments until the final maturity date in 2006. Approximately $93,428 
of the Revolving Credit Facility is available at December 31, 1997 reflecting 
letters of credit of $6,572 drawn against the Revolving Credit Facility of 
$100,000. In February 1998, the Senior Credit Facilities were amended to, 
among other things, increase the Revolving Credit Facility to $200,000, waive 
certain excess cash flow prepayments, as defined, otherwise required and 
permit the incurrence of up to an additional $150,000 of subordinated debt. 
The Company pays a commitment fee of 0.375% per annum on the unused portion 
of the Revolving Credit Facility. 
    

   In April 1997, the Company issued $225,000 of 10 3/8% senior subordinated 
notes (the "1997 Notes") due May 1, 2007 with interest payable semi-annually 
on May 1 and November 1 of each year, commencing November 1, 1997. On 
November 5, 1997, the Company completed its exchange offer relating to the 
1997

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.

through 2002 are: $5,000, $11,000, $19,000, $25,000 and $33,200, 
respectively. 
    

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

9. PREDECESSOR COMPANY'S INTEREST EXPENSE 

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

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

10. FINANCIAL INSTRUMENTS 

   The Company's financial instruments consist primarily of cash and cash 
equivalents, billed contract receivables, other billed receivables 
(principally commercial and affiliates), trade accounts payable, customer 
advances, debt instruments, and interest rate cap and interest rate floor 
contracts. The book values of cash and cash equivalents, billed contract 
receivables, other billed receivables (principally

commercial and affiliates), trade accounts payable and customer advances are 
considered to be representative of their respective fair values at December 
31, 1997 due to the short-term maturities or expected settlement dates of 
these instruments. 

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

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

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

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

THE COMPANY 

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

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

PREDECESSOR COMPANY 

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

12. STOCK OPTIONS 

THE COMPANY 

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

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

   
   On July 1, 1997 and November 11, 1997, Holdings granted nonqualified 
options to certain officers and other employees of the Company to purchase at 
$6.47 per share 689,500 shares of Class A common stock of Holdings 
(collectively, the "1997 Options"). Generally, the 1997 Options vest over a 
three-year vesting period and expire ten years from the date of grant. 

   The exercise price for Holdings' stock options granted to employees in 
1997 equaled the estimated fair value of Holdings' common stock at the date 
of grant. Accordingly, in accordance with APB 25, no compensation expense was 
recognized by the Company. 

   Pro forma information regarding net earnings as required by SFAS 123 has 
been determined as if the Company had accounted for its employee stock 
options under the fair value method. Because Holdings is a nonpublic entity 
the fair value for the options was estimated at the date of grant using the 
minimum value method prescribed in SFAS 123, which does not consider the 
expected volatility of Holdings' stock price, with the following 
weighted-average assumptions for 1997: risk-free interest rate of 6.3%; 
dividend yield of 0%; and weighted-average expected option life of 5.49 
years.

    For purposes of pro forma disclosures, the compensation cost of the 
options based on their estimated fair values is amortized to expense over 
vesting periods of the options. The Company's net income for the nine months 
ended December 31, 1997 would have decreased to the pro forma amounts 
indicated below:

   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, Holdings and the Company have 
agreed to assume certain on-site and off-site environmental liabilities 
related to events or activities occurring prior to the consummation of the 
L-3 Acquisition. Lockheed Martin has agreed to retain all environmental 
liabilities for all facilities not used by the Businesses as of April, 1997 
and to indemnify fully Holdings for such prior site environmental 
liabilities. Lockheed Martin has also agreed, for the first eight years 
following April 1997 to pay 50% of all costs incurred by Holdings above those 
reserved for on the Company's balance sheet at March 31, 1997 relating to 
certain Company-assumed environmental liabilities and, for the seven

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. 

14. PENSIONS AND OTHER EMPLOYEE BENEFITS 

THE COMPANY 

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

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

</TABLE>

   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.

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

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

THE PREDECESSOR COMPANY 

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

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

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

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

   Lockheed Martin provides the Company information systems and other 
services and previously provided similar services to the Predecessor Company 
for which the Company and the Predecessor Company was charged certain amounts
for the nine months ended December 31, 1997, the three months ended 
March 31, 1997 and the years ended December 31, 1996 and 1995.

   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. 

18. 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 common stock for a 
proposed maximum aggregate offering of $100,000.

                        REPORT OF INDEPENDENT AUDITORS 

Board of Directors of 
 L-3 Communications Corporation: 

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

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

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

1. BACKGROUND AND DESCRIPTION OF BUSINESS 

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

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

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

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

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

2. BASIS OF PRESENTATION 

BASIS OF COMBINATION 

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

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

ALLOCATION OF CORPORATE EXPENSES 

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

INCOME TAXES 

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

INTEREST EXPENSE 

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

STATEMENTS OF CASH FLOWS 

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

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

CONTRACTS IN PROCESS 

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

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

DEPRECIATION AND AMORTIZATION 

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

                              F-33           
<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.

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

</TABLE>

6. INCOME TAXES 

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

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

8. COMMITMENTS AND CONTINGENCIES 

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

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

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

9. PENSIONS AND OTHER EMPLOYEE BENEFITS 

PENSIONS 

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

POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS 

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

EMPLOYEE SAVINGS PLANS 

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

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

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

BASIS OF PRESENTATION 

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

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

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

USE OF ESTIMATES; RISKS AND UNCERTAINTIES 

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

INVENTORIES AND COST OF PRODUCTS SOLD 

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

3. CORPORATE ALLOCATIONS 

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

   No interest is allocated by CMI to the Division. 

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

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

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

4. RESTRUCTURING 

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

5. OTHER 

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

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

                        REPORT OF INDEPENDENT AUDITORS 

The Board of Directors 
California Microwave, Inc. 

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

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

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

                          CALIFORNIA MICROWAVE, INC. 

                        NOTES TO FINANCIAL STATEMENTS 

                   YEARS ENDED JUNE 30, 1995, 1996 AND 1997 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

BASIS OF PRESENTATION 

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

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

USE OF ESTIMATES; RISKS AND UNCERTAINTIES 

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

CASH AND CASH EQUIVALENTS 

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

INVENTORIES AND COST OF PRODUCTS SOLD 

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

PROPERTY, PLANT AND EQUIPMENT 

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

INTANGIBLE ASSETS OF BUSINESS ACQUIRED 

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

                              F-50

                  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.

   The Division had revenues from one customer representing 17.3%, 31.5% and 
11% of total revenues in 1995, 1996 and 1997, respectively. 

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-62           
<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>

(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:

                                               $550,000

</TABLE>

                              F-63           
<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:

     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:

   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.

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

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-72

                    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

</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

</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

 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)%

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.

Communications Corporation (the "Company" or "L-3") have been issued by the 
Company. The payment of principal, premium, if any, and interest on the Notes 
is guaranteed (the "Guarantees") on a senior subordinated basis by all of L-3 
Communications' Restricted Subsidiaries, including Hygienetics Environmental
Services, Inc., L-3 Communications ILEX Systems, Inc. and Southern California
Microwave, Inc. (the "Guarantors"), other than Foreign Subsidiaries. 

   Interest on the Notes will be payable semi-annually on     and      of 
each year, commencing    , 1998. The Notes will be redeemable at the option 
of the Company, in whole or in part, at any time on or after   , 2003, at the 
redemption prices set forth herein, plus accrued and unpaid interest to the 
date of redemption. In addition, prior to      , 2001, the Company may redeem 
up to 35% of the aggregate principal amount of Notes at the redemption price 
set forth herein plus accrued and unpaid interest through the redemption date 
with the net cash proceeds of one or more Equity Offerings. The Notes will 
not be subject to any mandatory sinking fund. In the event of a Change of 
Control, each holder of Notes will have the right, at the holder's option, to 
require the Company to purchase such holder's Notes at a purchase price equal 
to 101% of the principal amount thereof, plus accrued and unpaid interest to 
the date of purchase. See "Description of the Notes". The Company's ability 
to pay cash to the holders of Notes upon a purchase may be limited by the 
Company's then existing financial resources. There can be no assurance that 
sufficient funds will be available when necessary to make any required 
purchases. 

   The Notes will be general unsecured obligations of the Company, 
subordinate in right of payment to all existing and future Senior Debt of the 
Company. As of December 31, 1997, after giving pro forma effect to the 
Offerings, application of the net proceeds therefrom and borrowings under the 
Senior Credit Facilities, the Company would have had approximately $433.6 
million of indebtedness outstanding, of which $58.6 million would have been 
Senior Debt (excluding letters of credit). See "Capitalization".

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS. 

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

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

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

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

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

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

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

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

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

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

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES. 

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

ITEM 17. UNDERTAKINGS. 

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

   (b) The undersigned Registrant hereby undertakes that: 

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

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

               (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

          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,

<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

               (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

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

Borrower of such request.

have occurred, each Lender will, on the date such Loan was to have been made,

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

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

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

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



                                       28

<PAGE>




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.



                                       29

<PAGE>




                 (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.

                 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

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

6.13(b) has changed, it shall give written notice of such change to the
Administrative Agent. Upon the occurrence and during the continuance of an
Event of Default, the Administrative Agent may, and shall at the direction of
the Required Lenders, transmit any such notice of assignment received by it

                 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
the appropriate governmental entities or such Collateral is served by insurable
easements (or rights-of-way) for ingress and egress to and from such streets
(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.

                 6.15  Arrangements with the Seller.

                 (a) As promptly as practicable, but in any event within 90
         days following the Closing Date, the Borrower shall have delivered to
         the Administrative Agent the Supply Agreement, the License Agreement
         and the Interim Services Agreement (each as defined in the Transaction
         Agreement) executed and delivered by the Seller and the Borrower which
         shall be reasonably satisfactory in form and substance to the Agents;
         and

                 (b) As promptly as practicable, but in any event within 120
         days following the Closing Date, the Borrower shall have delivered to
         the Administrative Agent the executed consents of the lessors of the
         real property leased by the Seller (which leaseholds constitute
         Transferred Assets (as defined in the Transaction Agreement)) to the
         transfer of such leaseholds to the Borrower, which consents shall be
         reasonably satisfactory in form and substance to the Agents.

         other action seeking issuance of a warrant of attachment, execution,
         distraint or similar process against all or any substantial part of
         its assets which results in the entry of an order for any such relief

         pending appeal within 60 days from the entry thereof; or (iv)
         Holdings, the Borrower or any of its Subsidiaries shall take any

         transaction" (as defined in Section 406 of ERISA or Section 4975 of
         the Code) involving any Plan, (ii) any "accumulated funding
         deficiency" (as defined in Section 302 of ERISA), whether or not
         waived, shall exist with respect to any Plan or any Lien in favor of
         the PBGC or a Plan shall arise on the assets of the Borrower or any
         Commonly Controlled Entity, (iii) a Reportable Event shall occur with
         respect to, or proceedings shall commence to have a trustee appointed,
         or a trustee shall be appointed, to administer or to terminate, any
         Single Employer Plan, which Reportable Event or commencement of
         proceedings or appointment of a trustee is, in the reasonable opinion
         of the Required Lenders, reasonably likely to result in the
         termination of such Plan for purposes of Title IV of ERISA, (iv) any
         Single Employer Plan shall terminate for purposes of Title IV of
         ERISA, (v) the Borrower or any Commonly Controlled Entity shall, or in

         events or conditions, if any, could reasonably be expected to have a
         Material Adverse Effect; or

                 (h) One or more judgments or decrees shall be entered against
         Holdings, the Borrower or any of its Subsidiaries involving in the
         aggregate a liability (not paid or fully covered by insurance (which
         coverage has been acknowledged by the appropriate insurers)) of
         $7,500,000 or more, and all such judgments or decrees shall not have
         been vacated, discharged, stayed or bonded pending appeal within 60
         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

                 (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

privilege. The rights, remedies, powers and privileges herein provided are

foregoing relating to the violation of, noncompliance with or liability under,
any Environmental Law applicable to the operations of the Borrower, any of its
Subsidiaries or any of the Properties (all the foregoing in this clause (d),
collectively, the "indemnified liabilities"), it being understood that the
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

indemnified liabilities following the sale, leasing or other transfer of such

                 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.

         Revolving Credit Commitments under subsection 2.4, 2.5 or 2.6 or (ii)
         any recalculation of the Exchange Rate pursuant to subsection 3.9, 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
         or recalculation shall be accompanied by prepayment in the amount of

         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

         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.


                                       6


<PAGE>



                           (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
inserting immediately following the words "as if made on and as of such date"
in such subsection the parenthetical "(including, without limitation, the
representation and warranty set forth in subsection 4.7 of this Agreement with
respect to each of the Subordinated Debt Documents)".

         (q) Subsection 6.2(c) of the Credit Agreement is hereby amended by
deleting the reference to "the chief financial officer" therein and inserting
the words "a Responsible Officer" therefor.

         (r) The following shall be added to the Credit Agreement as subsection
6.16 of the Credit Agreement:

                  "6.16 Foreign L/Cs. Within one (1) Business Day of any day
         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
         Credit Loans of all Revolving Credit Lenders less the aggregate
         principal amount of the Swing Line Loans then outstanding exceeds such
         Foreign L/C Overdrawn Amount and (iii) the Borrower is otherwise in
         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
         such accounts shall be released to the Borrower on any Calculation
         Date on which the Foreign L/C Obligations equal or are less than the
         Foreign L/C Sublimit."

         (s) The following shall be added to the Credit Agreement as subsection
6.17 of the Credit Agreement:

                  "6.17 New Subordinated Debt Documents. At least ten Business
         Days prior to the date of issuance of the New Subordinated Notes, the
         Borrower shall deliver to the Agents copies of the New Subordinated
         Debt Documents. The New Subordinated Debt Documents shall be in form
         and substance satisfactory to the Agents."

         (t) Subsection 7.2(e) of the Credit Agreement is hereby stricken and
amended to read as follows:

                  "(e) Indebtedness of the Borrower in respect of not more than
         (i) $225,000,000 principal amount of Subordinated Notes issued on the
         Closing Date and (ii) $150,000,000 principal amount of New
         Subordinated Notes; provided that, to the extent that any of the Net

         normal banking procedures in the relevant jurisdiction purchase the

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

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.

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.

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).

<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.

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.

     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

     delivered to the Registrar to effect the transfers described in this

     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

     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

     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

          States.

        (iii) A Holder of Unrestricted Definitive Notes may transfer such Notes

     HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE SECURITY
     EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE."

               (B) Notwithstanding the foregoing, any Global Note or Definitive

          (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.06 (and

        (iii)  Regulation S Temporary Global Note Legend.  The Regulation S
     Temporary Global Note shall bear a legend in substantially the following
     form:

     "THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE
     CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES,
     ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER
     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.

          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

<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.

Section 4.01.  Payment of Notes.

          The Company shall pay or cause to be paid the principal of, premium,
if any, and interest on the Notes on the dates and in the manner provided in
the Notes. Principal, premium, if any, and interest shall be considered paid on
the date due if the Paying Agent, if other than the Company or a Subsidiary
thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. The Company shall
pay 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:

     required to be contained in a filing with the Commission on Forms 10-Q and

     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

     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

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

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.

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

     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

     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.

Section 4.08.  Dividend and Other Payment Restrictions Affecting
               Subsidiaries.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(A) pay dividends or make any other distributions
to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock
or (2) with respect to any other interest or participation in, or measured by,
its profits, or (B) pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries, or (iii) transfer any of its properties or assets
to the Company or any of its Restricted Subsidiaries, except for such
encumbrances or restrictions existing under or by reason of (A) the provisions
of security agreements that restrict the transfer of assets that are subject to
a Lien created by such security agreements, (B) the provisions of agreements
governing Indebtedness incurred pursuant to clause (v) of the second paragraph
of Section 4.09, (C) this Indenture and the Notes, (D) applicable law, (E) any
instrument governing Indebtedness or Capital Stock of a Person acquired by the
Company or any of its Restricted Subsidiaries as in effect at the time of such
acquisition (except to the extent such Indebtedness was incurred in connection
with or in contemplation of such acquisition), which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person, so acquired,
provided that, in the case of Indebtedness, such Indebtedness was permitted by
the terms of this Indenture to be incurred, (F) by reason of customary
non-assignment provisions in leases entered into in the ordinary course of
business and consistent with past practices, (G) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions
of the nature described in this clause (iii) on the property so acquired, (H)
Permitted Refinancing Indebtedness, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are no more
restrictive than those contained in the agreements governing the Indebtedness
being refinanced, (I) contracts for the sale of assets, including, without
limitation, customary restrictions with respect to a Subsidiary pursuant to an
agreement that has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Subsidiary, (J)
agreements relating to secured Indebtedness otherwise permitted to be incurred
pursuant to 4.09 and 4.12 that limit the right of the debtor to dispose of the
assets securing such Indebtedness, (K) restrictions on cash or other deposits
or net worth imposed by customers under contracts entered into in the ordinary
course of business, or (L) customary provisions in joint venture agreements and
other similar agreements entered into in the ordinary course of business.

Section 4.09.  Incurrence of Indebtedness and Issuance of Preferred Stock.

     The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect
to (collectively, "incur") any Indebtedness (including Acquired Debt) and that
the Company shall not issue any Disqualified Stock and shall not permit any of
its Subsidiaries to issue any shares of preferred stock; provided, however,
that the Company and any Restricted Subsidiary may incur Indebtedness
(including Acquired Debt) or issue shares of preferred stock if the Fixed
Charge Coverage Ratio for the Company's most recently ended four

                                       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
     Facilities (and the guarantee thereof by the Guarantors); provided that
     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
     all repayments, optional or mandatory, of the principal of any
     Indebtedness under a Credit Facility (or any such Permitted Refinancing
     Indebtedness) that have been made since the Issue Date;

         (ii) the incurrence by the Company of revolving credit Indebtedness
     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
     Section 4.10;

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

         (iv)  the incurrence by the Company and the Guarantors of the Notes
     and the Subsidiary Guarantees;

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

         (vi)  the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness in connection with the acquisition of

                                       52

<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
     net proceeds of which are used to refund, refinance or replace,
     Indebtedness that was permitted by this Indenture to be incurred;

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

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

          (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
     that is permitted by the terms of this Indenture to be outstanding or (B)
     protecting the Company and its Restricted Subsidiaries against changes in
     currency exchange rates;

        (xii) the guarantee by the Company or any of the Guarantors of
     Indebtedness of the Company or a Restricted Subsidiary of the Company that
     was permitted to be incurred by another provision of this Section
     4.09;

       (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

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

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

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

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.

          (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

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,

          (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

     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

of the Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of

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.

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.

Section 6.05.  Control by Majority.

          Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

Section 6.06.  Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

          (a)  the Holder of a Note gives to the Trustee written notice of a
continuing Event of Default;

          (b) the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy;


          (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

          (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

          (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07.  Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or
to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

Section 6.08.  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09.  Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel)
and the Holders of the Notes allowed in any judicial proceedings relative to
the Company (or any other obligor upon the Notes), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder
to make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

Section 6.10.  Priorities.

          If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

                                       64

<PAGE>

          First:  to the Trustee, its agents and attorneys for amounts due
under Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

          Second:  to Holders of Notes for amounts due and unpaid on the
Notes for principal, premium and Liquidated Damages, if any, and interest,
ratably, without preference or priority of any kind, according to the amounts
due and payable on the Notes for principal, premium and Liquidated Damages,
if any and interest, respectively; and

          Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

Section 6.11.  Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.

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

     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.

          (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability
or expense.

          (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall
not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may
consult with counsel and the written advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection from liability
in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon.

not be responsible for the misconduct or negligence of any agent appointed with
due care.

powers conferred upon it by this Indenture.

demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

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

negligence on the part of any agent or attorney appointed with due care by it
hereunder.

Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Notes and this Indenture.

          (i) Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign. Any Agent may do the same with
like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11
hereof.

                                       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).

          A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA Section 313(d).
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

Section 7.07.  Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred
or made by it in addition to the compensation for its services. Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

          The Company shall indemnify the Trustee or any predecessor Trustee
against any and all losses, liabilities or expenses incurred by it arising out
of or in connection with the acceptance or administration of its duties under
this Indenture, including the costs and expenses of enforcing this Indenture
against the Company (including this Section 7.07) and defending itself against
any claim (whether asserted by the Company or any Holder or any other person)
or liability in connection with the exercise or performance of any of its
powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company
of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable fees and expenses of such counsel. The
Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld.

          The Trustee shall have a lien prior to the Notes as to all property
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
trust for the benefit of the Holders of particular Notes.

                                       68

          The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

          To secure the Company's payment obligations in this Section, the
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
interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA 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
acceptance of appointment as provided in this Section.

          The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing.
The Company may remove the Trustee if:

          (a)  the Trustee fails to comply with Section 7.10 hereof;

          (b) the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

          (c)  a Custodian or public officer takes charge of the Trustee or
its property; or

          (d)  the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office,
the Holders of a majority in principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

          If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Notes of at least 10% in principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

          If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note may petition any court of competent

                                       69

<PAGE>

jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien
provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

Section 7.09.  Successor Trustee by Merger, etc.

          If the Trustee consolidates, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the
successor Trustee.

Section 7.10.  Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or
state authorities and that has a combined capital and surplus of at least $50
million as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA 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.

          The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.  Option to Effect Legal Defeasance or Covenant Defeasance.

          The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

                                       70

<PAGE>

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.

Section 8.04.  Conditions to Legal or Covenant Defeasance.

          The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

          In order to exercise either Legal Defeasance or Covenant
Defeasance:

          (a) the Company must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent
public accountants, to pay the principal of, premium and Liquidated Damages, if
any, and interest on the outstanding Notes on the stated date for payment
thereof or on the applicable redemption date, as the case may be;

          (b) in the case of an election under Section 8.02 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Legal Defeasance had not occurred;

          (c) in the case of an election under Section 8.03 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Covenant Defeasance had not occurred;

          (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of
Default resulting from the incurrence of Indebtedness all or a portion of the
proceeds of which will be used to defease the Notes pursuant to this Article 8
concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

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

          (f) the Company shall have delivered to the Trustee an opinion of
counsel to the effect that on the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,

                                       72

<PAGE>

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.

          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.

Failure to mail a notice or communication to a Holder or any defect in it shall
not affect its sufficiency with respect to other Holders.

          If a notice or communication is mailed in the manner provided above

receives it.

          If the Company mails a notice or communication to Holders, it shall

          Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than a certificate

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.

     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
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

     14. No Recourse Against Others. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

     15.  Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

     17. 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.

     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

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.

     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

     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
interest on, or the principal of, the Notes.

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

     14. No Recourse Against Others. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

     15.  Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

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

     17. 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").

                                      104

     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.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to:

interest therein is subject to certain restrictions and conditions set forth in
the Indenture and the undersigned agrees to be bound by, and not to resell,
pledge or otherwise transfer the Notes or any interest therein except in

          2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes and any interest
therein may not be offered or sold except as permitted in the following

          3. We understand that, on any proposed resale of the Notes or
Book-Entry Interests, we will be required to furnish to you and the Company
such certifications, legal opinions and other information as you and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Notes purchased by
us will bear a legend to the foregoing effect. We further understand that any
subsequent transfer by us of the Notes or Book-Entry Interests therein acquired
by us must be effected through one of the Placement Agents.

          4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Notes, and
we and any accounts for which we are acting are each able to bear the economic
risk of our or its investment.

          5. We are acquiring the Notes or Book-Entry Interests purchased by us
for our own account or for one or more accounts (each of which is an
institutional "accredited investor") as to each of which we exercise sole
investment discretion.

          You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceedings or official inquiry
with respect to the matters covered hereby.

          WHEREAS, pursuant to Section 4.13 of the Indenture, the Trustee is

          NOW THEREFORE, in consideration of the foregoing and for other good

     2.   Agreement to Guarantee.  The Guaranteeing Subsidiary hereby agrees

          (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

               fraudulent conveyance or similar law.

               agrees that a notation of such Subsidiary Guarantee
               substantially in the form of Exhibit F to the Indenture shall be

               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

               be valid nevertheless.

          (d)  The delivery of any Senior Note by the Trustee, after the
               authentication thereof under the Indenture, shall constitute due

               Subsidiary.

               hereunder shall be unconditional, regardless of the validity,
               regularity or enforceability of the Notes or the Indenture,

               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

               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:

                    accelerated as provided in Article 6 of the Indenture for
                    the purposes of the Subsidiary Guarantee made pursuant to

                    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

               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.

     10.  The Trustee.  The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiary and the
Company.

          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

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

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

accordance with Section 2.4, each Stockholder may Transfer Shares only
following compliance and in accordance with the provisions of this Section 2.5
and, as applicable, Sections 2.6 or 2.7.

          (b) Any Stockholder desiring to Transfer Shares to any Third Party
(such Stockholder, in such capacity, a "Seller") shall give written notice (a
"Seller's Notice") to the other Stockholders and to the Company (i) stating
that such Seller desires to make such Transfer and (ii) setting forth the
number of Shares proposed to be Transferred (the "Offered Shares") and the cash
price per share that such Seller proposes to be paid for such Offered Shares
(the "Offer Price") and, to the extent then known, the other terms and
conditions of such Transfer, including the identity of any proposed transferee.
Each Seller's Notice shall constitute an irrevocable offer by the Seller to the
other Stockholders and to the Company of the Offered Shares at the Offer Price
in cash and in accordance with the terms of this Agreement.

          (c) Within 60 days after receipt of a Seller's Notice, each other
Stockholder may elect to purchase, on a pro rata basis based upon the total
number of outstanding Shares then held by such other Stockholders (provided
that any Offered Shares thereby offered to any other Stockholder that does not
elect to purchase such Offered Shares shall be reallocated (on a pro rata basis
based on the total number of Offered Shares each other Stockholder elected to
purchase) among the remaining other Stockholders who have elected to exercise
their option to purchase Offered Shares) all (but not less than all) of the
Offered Shares allocated to it at the Offer Price in cash. The Company may
elect, within 10 days following the expiration of such 60-day period, to
purchase at the Offer Price in cash all (but not less than all) of the Offered
Shares as to which no election to purchase is made by the other Stockholders
within such 60-day period. The election to purchase such Offered Shares shall
be exercisable by delivery of a notice (a "Buyer's Notice") to the Seller, with
a copy to the Company (where the Company is not the electing party), stating
(i) that such electing party elects to purchase such Offered Shares at the
Offer Price in cash, (ii) that such election is irrevocable and (iii) the
source of financing for such purchase, which financing shall not be subject to
any material contingencies. Delivery of a Buyer's Notice shall constitute a
contract among the Seller and the electing party that has delivered such
Buyer's Notice for the sale and purchase of the Offered Shares at the Offer
Price in cash and upon the other applicable terms and conditions set forth in
the Seller's Notice.

          (d) If the other Stockholders and the Company fail to elect to
purchase all of the Offered Shares within the time periods specified in Section
2.5(c), then the Seller may, within a period of 90 days following the
expiration of such time periods specified in Section 2.5(c), complete the
Transfer of all or any of the Offered Shares not purchased by the other
Stockholders or the Company to one or more Third Parties at a price per share
not less than 95% of the Offer Price; provided that if the purchase price per
share (the "Reduced Transfer Price") proposed to be paid by any such Third
Party for Offered Shares is less than 95% of the Offer Price, the Seller

                                       10

<PAGE>

shall promptly provide written notice (the "Reduced Transfer Price Notice") to
the other Stockholders and the Company of such intended Transfer (including the
material terms and conditions thereof) and the other Stockholders and the
Company shall have the right, exercisable by delivery of a written election
notice to the Seller within 30 days of receipt of such notice, to purchase such
Offered Shares at the Reduced Transfer Price and otherwise substantially in
accordance with the terms and conditions of the intended Transfer to such Third
Party, following which 30-day period, if no such election is made, Section
2.5(e) shall apply.

          (e) If the other Stockholders and the Company fail to elect to
purchase all of the Offered Shares at the Reduced Transfer Price in cash within
the 30-day period specified in Section 2.5(d), then the Seller may, within a
period of 90 days following the expiration of such 30-day period, complete the
Transfer of all or any of the Offered Shares to one or more Third Parties at a
price per share not less than 95% of the Reduced Transfer Price; provided that
if the purchase price per share (the "Second Reduced Transfer Price") proposed
to be paid by any such Third Party for Offered Shares is less than 95% of the
Reduced Transfer Price, the Seller shall promptly provide written notice (the
"Second Transfer Price Notice") to the other Stockholders and the Company of
such intended Transfer (including the material terms and conditions thereof)
and the other Stockholders and the Company shall have the right, exercisable by
delivery of a written election notice to the Seller within 30 days of receipt
of such notice, to purchase such Offered Shares at the Second Reduced Transfer
Price and otherwise substantially in accordance with the terms and conditions
of the intended Transfer to such Third Party.

          (f) If the other Stockholders and the Company fail to elect to
purchase all of the Offered Shares at the Offer Price (or, if applicable, the
Reduced Transfer Price or Second Reduced Transfer Price) in cash and the Seller
shall not have Transferred the Offered Shares to any Transferee prior to the
expiration of the 90-day period specified in Section 2.5(e), the rights of
first offer under this Section 2.5 shall again apply in connection with any
subsequent Transfer or offer to Transfer shares of Common Stock by such
Sellers.

          Section 2.6. Tag Along Right. (a) If at any time on or after the
first anniversary of the Effective Date and prior to the consummation of an
Initial Public Offering, Lehman and/or LBHI (and/or their Permitted
Transferees) proposes to Transfer Shares to any Person (other than a Permitted
Transferee) (each, a "Proposed Transferee") in any transaction or series of
related transactions and as a result of such Transfer, Lehman and LBHI (with
their Permitted Transferees) would no longer own at least 35% of the issued and
outstanding Common Stock, then Lehman shall send written notice to each
Management Investor and Lockheed Martin which shall state (i) that Lehman
and/or LBHI and/or their Permitted Transferees desires to make such a Transfer,
(ii) the identity of the Proposed Transferee and the number of Shares proposed
to be sold or otherwise transferred, (iii) the proposed purchase price per
Share to be paid and the other terms and conditions of such Transfer and (iv)
the projected closing date of such Transfer, which in no event shall be prior
to 30 days after the giving of such written notice to each Management Investor
and Lockheed Martin.

          (b) For a period of 30 days after the giving of the notice pursuant
to clause (a) above, each Management Investor and Lockheed Martin shall have
the right to sell to the Proposed Transferees in such Transfer at

                                       11

<PAGE>

the same price and upon the same terms and conditions as Lehman, LBHI (and/or
their Permitted Transferees) that percentage of the total number of Shares held
by such Management Investor or Lockheed Martin, as the case may be, equal to
the percentage of the total number of Shares then held by Lehman, LBHI and
their Permitted Transferees proposed to be Transferred to such Proposed
Transferee; provided that neither Management Investor shall have the right to
sell any of its Shares Subject to Forfeiture pursuant to this Section 2.6(b) if
the price per share to be obtained by Lehman in such Transfer is less than
$6.47.

          (c) The rights of each Management Investor and Lockheed Martin under
Section 2.6(b) shall be exercisable by delivering written notice thereof, prior
to the expiration of the 30-day period referred to in clause (b) above, to
Lehman with a copy to the Company; provided that Lockheed Martin shall not be
entitled to exercise any rights under this Section 2.6 if neither of the
Management Investors exercises his rights under this Section 2.6. The failure
of such Management Investor or Lockheed Martin to respond within such period to
Lehman shall be deemed to be a waiver of rights under this Section 2.6.

          (d) In the event that any Management Investor or Lockheed Martin
exercises rights under Section 2.6(b) and following such exercise there is a
change in the price or terms of the proposed transaction between Lehman and the
Proposed Transferee, then Lehman shall promptly notify such Management Investor
and Lockheed Martin of the revised price or terms and such Management Investor
or Lockheed Martin, as the case may be, shall have the right to exercise its
rights under Section 2.6(b) by notice to Lehman within two business days of
receipt of the notice from Lehman. The failure of such Management Investor or
Lockheed Martin to respond within such two-day period to Lehman shall be deemed
to be a waiver of his or its rights under this Section 2.6.

          (e) For purposes of determining the number of Shares a Management
Investor may Transfer pursuant to this Section 2.6, such Management Investor
shall be deemed to hold the shares of Common Stock issuable upon exercise of
any outstanding options to purchase Common Stock he holds so long as (i) such
options have vested and (ii) the exercise price of such options is below the
proposed price to be paid by the Proposed Transferee in the Transfer to which
such determination relates.

          Section 2.7. Bring Along Right. (a) If at any time on or after the
first anniversary of the Effective Date and prior to the consummation of an
Initial Public Offering, Lehman and/or LBHI (and/or their Permitted
Transferees) proposes to sell Shares to a Third Party other than an Affiliate
in any bona fide arm's-length transaction or series of related transactions and
as a result of such sale Lehman and LBHI with their Permitted Transferees would
cease to own at least 35% of the issued and outstanding Common Stock, then
Lehman shall have the right to deliver a written notice (a "Buyout Notice") to
each Management Investor (with a copy to Lockheed Martin) which shall state (i)
that Lehman proposes to effect such transaction, (ii) the identity of the Third
Party, the number of Shares to be sold and the proposed purchase price per
Share to be paid and any other terms and conditions, and (iii) the projected
closing date of such sale. Each such Management Investor agrees that, upon
receipt of a Buyout Notice, each such Management Investor (and his Permitted
Transferees) shall be obligated to sell in such transaction that percentage of
the total number of Shares held by such Management Investor (determined on the
basis set forth in Section 2.6(e))

                                       12

equal to the percentage of the total number of Shares then held by Lehman and
LBHI and their Permitted Transferees to be sold in such transaction upon the
terms and conditions of such transaction (and otherwise take all necessary
action to cause consummation of the proposed transaction; provided, however,
that each such Management Investor shall only be obligated as provided above in
this Section 2.7 if each such Management Investor receives the same per Share
consideration as Lehman and LBHI (and/or their Permitted Transferees); and
provided further that in no event shall any Management Investor be required to
make any representations or provide any indemnities other than on a
proportionate basis and other than with respect to matters relating solely to
Lehman and LBHI (and/or its Permitted Transferees), such as representations as
to title to Shares to be transferred by Lehman and LBHI or their Permitted
Transferees.

          (b) At any time that Lehman exercises its rights under this Section
2.7, Lockheed Martin shall have the right, but not the obligation, to sell in
the transaction specified in the Buyout Notice at the same price and upon the
same terms and conditions as Lehman and/or LBHI (and/or their Permitted
Transferees) and the Management Investors that percentage of the total number
of Shares held by Lockheed Martin equal to the percentage of the total number
of Shares then held by Lehman and LBHI and their Permitted Transferees to be
sold in such transaction. The rights of Lockheed Martin under this Section
2.7(b) shall be exercisable by delivering written notice thereof at least 10
days prior to the proposed closing date of such transaction.

          Section 2.8. Registration Rights. The Company hereby grants to each
Stockholder the registration and other rights set forth in, and each
Stockholder agrees to comply with the terms and conditions contained in,
Exhibit C.

                                    CLOSING

          Section 3.1. Closing. Any Stockholders acquiring or Transferring any
Shares pursuant to Section 2.5 shall mutually determine a closing date (the
"Transfer Closing Date") which, subject to any applicable regulatory waiting
periods, shall not be more than 60 days after the last notice is given with
respect to such Transfer pursuant to Section 2.5 or after the expiration of the
last notice period pursuant to Section 2.5 applicable to such Transfer. The
closing shall be held at 10:00 a.m., local time, on the Transfer Closing Date
at the principal office of the Company, or at such other time and/or place as
the parties may mutually agree.

          Section 3.2. Deliveries at Closing; Method of Payment of Purchase
Price. On the Transfer Closing Date, each selling Stockholder shall deliver (i)
certificates representing the Shares being sold, free and clear of any lien,
claim or encumbrance, and (ii) such other documents, including evidence of
ownership and authority, as the Transferees may reasonably request. The

                                  ARTICLE IV
                       ADDITIONAL RIGHTS AND OBLIGATIONS
                        OF STOCKHOLDERS AND THE COMPANY

          Section 4.1. Preemptive Rights. If the Company shall (other than in
connection with the issuance of Shares or Share Equivalents (i) to employees,
officers and directors of or any of its direct or indirect subsidiaries with
respect to any employee benefit plan, incentive award program or other
compensation arrangement approved by the affirmative vote of a majority of the
outstanding shares and (ii) as all or a portion of the consideration for the
purchase of capital stock or assets of another Person) (A) issue any Shares,
(B) issue any Share Equivalents or (C) enter into any contracts, commitments,
agreements, understandings or arrangements of any kind relating to the issuance
of any Shares or Share Equivalents (in each case other than in connection with
the Initial Public Offering), each Stockholder shall have the right to purchase
that number of Shares (or Share Equivalents, as the case may be) at the same
purchase price as the price for the additional Shares (or Share Equivalents) to
be issued so that, after the issuance all of such Shares (or Share
Equivalents), together with all Shares (or Share Equivalents) to be issued
pursuant to this Section 4.1 in connection therewith, the Stockholder would, in
the aggregate, hold the same proportional interest of the outstanding Shares
(assuming, in the case of an issuance of Share Equivalents, the conversion,
exercise or exchange thereof) as was held by such Stockholder prior to the
issuance of such additional Shares (or Share Equivalents).

          Section 4.2. Future Services. The Company agrees that Lehman Brothers
Inc. ("Lehman Brothers") shall have the right, but not the obligation, which
right shall be exercisable in Lehman Brothers' sole discretion, to provide
investment banking services to the Company on an exclusive basis for a period
of five years from the Effective Date (the "Exclusivity Period"); provided that
as to acquisitions undertaken by the Company for cash, the Exclusivity Period
shall be the three year period after the Effective Date. Such services may
include arranging senior and subordinated debt financing for the Company,
underwriting on a sole managed basis or acting as the sole initial purchaser or
placement agent for the Company's or its affiliates' debt and/or equity
securities, acting as the exclusive financial advisor to the Company with
respect to any mergers, acquisitions or divestitures for which the services of
an investment banking firm are utilized and providing other financial advisory
services on an exclusive basis. In the event that Lehman Brothers agrees to
provide any investment banking services to the Company, Lehman Brothers shall
be paid fees to be mutually agreed upon based on fees which are competitive
based upon similar transactions and practices in the investment banking
industry. The Company acknowledges that Lehman Brothers may determine in its
sole discretion for any reason (including, without limitation, the results of
its due diligence investigation, a material change in the Company's financial
condition, business, management, prospects or value, the lack of appropriate
internal Lehman Brothers' committee approvals or then current market
conditions) not to provide such investment banking services to the Company. In
the event that Lehman Brothers elects not to provide such services to the
Company with respect to any particular transaction, nothing contained herein
shall be deemed to prevent the Company from utilizing the services of another
investment banking firm for such transaction or to require the Company to pay a
fee to Lehman Brothers with respect to such transaction, but such retention of
another investment banking firm shall be without prejudice to Lehman Brothers'
rights hereunder with respect to subsequent transactions.

          Section 4.3. Regulatory Event. If (a) the Company receives
notification from a representative of the Department of Defense or any other
U.S. government department, agency or authority that the ownership of Shares by
Lehman and/or LBHI or the terms and provisions of this Agreement or the Charter
Documents (i) causes the Company to be under impermissible foreign ownership,
control or influence ("FOCI") within the meaning of Section 721 of Title VII of
the Defense Production Act of 1950, as amended by Section 5021 of the Omnibus
Trade and Competitiveness Act of 1988, or (ii) materially adversely affects the
ability of the Company to maintain or obtain Department of Defense or other
U.S. government department, agency or authority security clearance of the level
held by the Business and their employees on the Effective Date or which are
necessary or desirable for the Company to perform and to bid competitively on
U.S. government contracts and to participate in joint ventures formed to bid on
or perform U.S. government contracts of the type the Business is eligible to
bid on or participate in, respectively, on the Effective Date (any of the
matters described in this clause (ii) being referred to as "Adverse Clearance
Status"), and such FOCI or Adverse Clearance Status is not a result of a change
in (A) the ownership of Lehman or LBHI from the ownership thereof as it exists
as of the Effective Date or (B) applicable law, regulations and decrees as in
effect as of the Effective Date, Lehman and/or LBHI may, within 60 days of
becoming aware of such notification, upon delivery of a written notice (a
"Regulatory Event Notice") to the Company, require the Company (i) to
repurchase (the "Put") such portion of the Shares then held by Lehman and/or
LBHI required to eliminate such FOCI or Adverse Clearance Status (the
"Regulatory Portion") for an amount in cash equal to the fair market value of
the shares subject to the Put as determined by an investment bank of national
reputation which is mutually acceptable to the Company (as determined by the
Board of Directors of the Company without the participation by any directors
designated by Lehman pursuant to this Agreement) and Lehman or (ii) to commence
a Public Offering which shall include the registration and offering of the
Regulatory Portion in accordance with the registration procedures contained in
Exhibit C; provided, that prior to delivery of any Regulatory Event Notice
Lehman and/or LBHI shall have complied with Section 4.4; and provided further,
that the Company shall not be required to take any action under this Section
4.3 that it is prohibited from taking under the terms of any of its financing
agreements or under applicable law.

          Section 4.4. Regulatory Compliance. (a) If any of the circumstances
described in Section 4.3 occur and would (x) cause the Company to be under FOCI
or (y) result in Adverse Clearance Status and such FOCI and Adverse Clearance
Status, if any, may be eliminated to the complete satisfaction of all
applicable U.S. government departments, agencies or authorities solely by the
adoption by Lehman or LBHI or the Board of Directors of the Company of
governance procedures or board resolutions insulating the Company from
impermissible control or influence of any foreign entity in accordance with the
National Industrial Security Program Operating Manual (DOD 5220.22M), then
Lehman or LBHI or the Board of Directors of the Company, shall adopt such
procedures or board resolutions, provided that such procedures and/or board
resolutions do not contravene and are consistent with applicable law and do not
materially and adversely affect the governance and other rights (whether
exercised directly or in accordance with such procedures) of Lehman or LBHI
contained in this Agreement and the Charter Documents and any other agreements
or documents relating thereto.

          (b) If such FOCI and Adverse Clearance Status, if any, are not
eliminated following compliance with paragraph (a) above, and such FOCI and

                                       15

<PAGE>

Adverse Clearance Status, if any, may be eliminated by a Transfer of Shares
held by Lehman or LBHI to an Affiliate, Lehman or LBHI, as the case may be,
shall use its reasonable efforts to effectuate such Transfer, provided that any
such Transfer shall not contravene, and is made in compliance with, Lehman's
and/or LBHI's customary business practices.

          (c) If there is a change in the ownership of Lehman from the
ownership thereof as it exists as of the Effective Date and such change in
ownership causes the Company to be under impermissible FOCI or otherwise
results in an Adverse Clearance Status, and such FOCI or Adverse Clearance
Status, as the case may be, cannot be eliminated through the procedures
contemplated by Section 4.4(a) or Section 4.4(b), the Company shall have the
option, exercisable within 30 days after it concludes that the measures
contemplated by Section 4.4(a) and Section 4.4(b) are not sufficient to
eliminate the FOCI or Adverse Clearance Status, to purchase (the "Call") the
Regulatory Portion of the Shares then held by Lehman and/or LBHI for an amount
in cash equal to the fair market value of the Shares subject to the Call as
determined by an investment bank of national reputation which is mutually
acceptable to the Company (as determined by the Board of Directors of the
Company without the participation by any directors designated by Lehman
pursuant to this Agreement) and Lehman.

          Section 4.5. Standstill Agreement. Lockheed Martin agrees that it
will not, and it will cause its Permitted Transferees not to, directly or
indirectly (through Affiliates or otherwise), acquire any shares of Common
Stock if immediately following such acquisition of shares of Common Stock,
Lockheed Martin and its Affiliates would own more than 34.9% of the outstanding
shares of Common Stock; provided that this Section 4.5 shall not limit any of
Lockheed Martin's rights under Section 2.5 or Section 4.1 of this Agreement.

               Section 4.6. Certain Other Agreements. If at any time prior to
Payment in Full of the Preference Amount a merger or other similar transaction
is consummated pursuant to which 90% or more of the outstanding equity
interests in the Company are acquired by a Person other than an Affiliate of
Lehman at a price per share which is less than $6.47 (an "Acquisition
Transaction"), then each of the Stockholders agrees to enter into such other
agreements or other arrangements as may be required in order that the proceeds
to the Stockholders from such Acquisition Transaction are distributed as among
the holders of each class of Common Stock in a manner comparable to the manner
in which such proceeds would be distributed in a distribution of assets of the
Company in the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the Company in accordance with the terms of the Certificate of
Incorporation.

                                   ARTICLE V
                           CERTAIN VOTING AGREEMENTS

          Section 5.1. Board of Directors of the Company. (a) The Company's
Board of Directors shall be initially composed of eleven members. Lehman shall
be entitled, but not required, to designate six members (the "Lehman Nominees")
of the Board of Directors. Lockheed Martin shall be entitled, but not required,
to designate three members (the "Lockheed Martin Nominees") of the Board of
Directors. In addition, each of Lanza and LaPenta shall be entitled, but not
required, to designate themselves as members of the Board of Directors for so
long as they are employees of the Company or

                                       16

<PAGE>

any of its Subsidiaries (the "Lanza Nominee" and "LaPenta Nominee",
respectively).

          (b) (i) Each of the Stockholders agrees to vote all of the Shares of
Class A Common Stock owned or held of record by such Stockholder at any regular
or special meeting of the stockholders of the Company called for the purpose of
filling positions on the Board of Directors, or in any written consent executed
in lieu of such a meeting of stockholders, and agrees to take all actions
otherwise necessary, to ensure the election to the Board of Directors of the
Lehman Nominees, the Lockheed Martin Nominees, the Lanza Nominee and the
LaPenta Nominee in accordance with the terms hereof.

          (ii) Each of the Company and each Stockholder hereby agrees to use
its or his best efforts to call, or cause the appropriate officers and
directors of the Company to call, a special meeting of stockholders of the
Company and to vote all of the Shares of Class A Common Stock owned or held of
record by such Stockholder for, or to take all actions by written consent in
lieu of any such meeting necessary to cause, the removal (with or without
cause) of (i) any Lehman Nominee if Lehman requests such director's removal for
any reason and (ii) any Lockheed Martin Nominee if Lockheed Martin requests
such director's removal for any reason. Lehman and Lockheed Martin shall have
the right to designate a new nominee in the event any Lehman Nominee or
Lockheed Martin Nominee, respectively, shall be so removed or shall vacate his
or her directorship for any reason.

          (c) Except as provided in Section 5.1(b)(ii) hereof, each Stockholder
hereby agrees that, at any time that it or he is then entitled to vote for the
election or removal of directors, it will not vote in favor of the removal of
any Lehman Nominee, Lockheed Martin Nominee, Lanza Nominee or LaPenta Nominee,
unless such removal shall be for Cause. For the purposes of this Section
5.1(c), "Cause" shall mean (i) as to any Lehman Nominee or Lockheed Martin
Nominee, the gross neglect of or willful and continuing refusal to
substantially perform his duties as a director, the willful engaging by a
director in conduct which is demonstrably and materially injurious to the
Company or the director's conviction of any crime constituting a felony and

breach of the restrictive covenants contained in such Management Investor's
employment agreement with the Company or any of its Subsidiaries, willful
engaging in conduct which is demonstrably injurious to the Company or the
Company's subsidiaries or affiliates or conviction or plea of guilty or nolo
contendere to a felony or a misdemeanor involving moral turpitude.

          (d)  The number of directors which Lehman and Lockheed Martin have
the right to designate pursuant to Section 5.1(a) shall be reduced from time
to time to take into account any reduction in Lehman's and Lockheed Martin's
(in either case, together with its Permitted Transferees) ownership level in
the issued and outstanding shares of Common Stock so that the percentage of
the total number of directors designated by each such party corresponds as
nearly as practicable to the percentage ownership of such party (with its
Permitted Transferees) of the issued and outstanding shares of Common Stock;
provided that so long as Lehman (with its Permitted Transferees) continues to
own at least 35% of the issued and outstanding Common Stock, the directors
designated by Lehman pursuant to Section 5.1(a) shall constitute a majority
of the Board of Directors so long as Lehman (with its Permitted Transferees)
continues to represent the largest single stockholder of the Company.  The

                                       17

<PAGE>

Stockholders' obligations under Section 5.1(b) and (c) shall remain in effect
with respect to the Lehman Nominees and Lockheed Martin Nominees, as reduced
pursuant to the preceding sentence.

          (e) The rights of Lehman, Lockheed Martin, Lanza and LaPenta to
designate Board members under Section 5.1(a) shall not be assignable (including
to any Transferee of Shares).

          Section 5.2.  Charter Documents.  (a) Exhibits A and B set forth
copies of the Certificate of Incorporation and By-laws of the Company, each
in the form in which it is to be in effect on the Effective Date (the
"Charter Documents").

          (b) The Company covenants and agrees that it will act in accordance
with the Charter Documents. Each Stockholder covenants and agrees that it will
vote all the Shares owned or held of record by such Stockholder at any regular
or special meeting of stockholders of the Company or in any written consent
executed in lieu of such a meeting of stockholders, and shall take all action
necessary, to ensure that the Charter Documents do not, at any time, conflict
with the provisions of this Agreement.

          Section 5.3. Consent to an Initial Public Offering; Required IPO. (a)
Prior to the first anniversary of the Effective Date, the Company shall not
commence an Initial Public Offering without the affirmative vote of (i) a
majority of the Lehman Nominees, (ii) a majority of the Lockheed Martin
Nominees, (iii) the Lanza Nominee and (iv) the LaPenta Nominee.

          (b) At any time on or after the fifth anniversary of the Effective
Date, if an Initial Public Offering shall not have been consummated prior to
such date, Lehman or Lockheed Martin (in each case, provided that it and its
Permitted Transferees then own at least 50% of the issued and outstanding
Common Stock owned by such party on the Effective Date) may require the Company
promptly to commence an Initial Public Offering and to complete such Initial
Public Offering as soon as reasonably practicable in accordance with the
registration procedures contained in Exhibit C. The rights of Lehman and
Lockheed Martin under this Section 5.3(b) shall not be assignable (including to
any Transferee of Shares).

                                  TERMINATION

          Section 6.1. Termination. The provisions of this Agreement, other
than Sections 2.8, 4.2 and 4.5 shall terminate upon the consummation of an
Initial Public Offering. Section 2.8 and the registration rights contained in
Exhibit C shall continue to apply following such consummation with respect to
all Registrable Securities (as defined in Exhibit C) in accordance with the
terms thereof. Section 4.2 shall continue to apply following the consummation
of an Initial Public Offering until the earlier of the expiration of the
Exclusivity Period or the date on which Lehman (together with its Permitted
Transferees) ceases to own at least 10% of the outstanding shares of Common
Stock. Section 4.5 shall continue to apply following such consummation until
the fifth anniversary of the Effective Date.

party in exercising any right, power or privilege hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law.

          (b) No amendment, modification or supplement to this Agreement shall

     Lockheed Martin and previously provided to the Purchasers (the "Long Range
     Plan"), but only to the extent in backlog at the Closing Date or
     contemplated as of the Closing in connection with Bids in existence as of
     the Closing, and in the case of the "Eagle" and "Raptor" (both long lead
     material award and production award) programs, profit chargebacks to
     Lockheed Martin of up to an aggregate of $1,000,000 and (2) providing
     that, notwithstanding the terms of the Long Range Plan, after December 31,
     2000 Newco shall not be entitled to any profit chargeback to Lockheed
     Martin) (the "Supply Agreement"), which agreement is to be negotiated by
     the parties in good faith prior to the Closing; and

<PAGE>

       (viii) Other than with respect to the matters referenced in clause (ix)
     below, Lockheed Martin (and/or other Lockheed Martin Companies, as
     appropriate) and Newco will enter into lease, sublease or assignment
     agreements, as the case may be, in respect of those facilities used by the
     Business Units on such terms and subject to such conditions as may be
     negotiated by the parties in good faith prior to the Closing, it being
     understood that such terms and conditions shall be consistent with
     existing agreements; and

         (ix) Lockheed Martin and Newco will enter into an agreement pursuant
     to which (A)(1) Lockheed Martin will agree for a period beginning on the
     Closing Date and ending on December 31, 1999, to lease 67,400 square feet
     of space in Building 1 at the Communications Systems Business Unit at an
     "all in" annual cost of $36.25 per square foot, (2) Newco will grant
     Lockheed Martin an option (exercisable on or prior to December 31, 1998)
     to continue to lease all of the space contemplated by the preceding clause
     (A)(1) for the period from January 1, 2000 until March 14, 2003 at an "all
     in" annual cost of $18.12 per square foot, and (3) Newco will agree to pay
     Lockheed Martin $2,000,000 on the first Business Day of January 2000 in
     the event that Lockheed Martin exercises the option contemplated by the
     preceding clause (A)(2), and (B) Lockheed Martin will agree to lease on
     behalf of its existing MAC-MAR business its current space in Building 1 at
     the Communications Systems Business Unit at the current lease rates
     through December 31, 1998, and will grant Newco the right, on a
     year-to-year basis, to match any competing offer to provide space and
     related services to MAC-MAR thereafter until the end of the current lease
     term, it being understood that Newco must continue to use the services of
     the MAC-MAR business as long as the MAC-MAR business is using Newco's
     receiving services at the Communications Systems Business Unit.

     Section 2.02 Exchange Consideration. The consideration to be paid to
Lockheed Martin and the Affiliated Transferors for the Transferred Assets (the
"Exchange Consideration") shall consist of the following:

          (i)   Subject  to adjustment  in  accordance with  Section 2.03  and
     Section 2.04, $479,835,000 in cash;

         (ii)  6,980,000 shares of Newco Class A Stock; and

        (iii)   Newco's assumption of  the Assumed  Liabilities in  accordance
     with this Agreement.

     Section 2.03   Adjustment of Exchange Consideration.

     (a) At least two Business Days prior to the Closing Date, Lockheed Martin
shall, in good faith and after consultation with the Individual Purchasers,
prepare an estimate of the Net Tangible Assets of the Business as of March 30
(if the Closing shall occur in April 1997) or April 27 (if the Closing shall
occur in May 1997) (such date being the date on which Lockheed Martin closes
its accounting books and records for the respective month and referred to as
the "Effective Date"; and such estimate being the "Estimated Final Net Tangible
Asset Amount") and shall provide a copy of its calculation of the Estimated
Final Net Tangible Asset Amount to Newco and the Purchasers.

     (b) Promptly following the Closing Date, but in no event later than 60
days after the Closing Date, Lockheed Martin shall, at its expense, with the

                                       10

<PAGE>

assistance of Newco prepare and submit to Newco an audited combined statement
of net tangible assets setting forth, in reasonable detail, Lockheed Martin's
calculation of the Net Tangible Assets of the Business as of the close of
business on the Effective Date (the "Proposed Final Net Tangible Asset Amount")
together with an opinion of Ernst & Young LLP stating that such audited
combined statement of Net Tangible Assets presents fairly, in all material
respects, the Net Tangible Assets of the Business as of the close of business
on the Effective Date in accordance with the provisions of this Agreement. In
the event Newco disputes the correctness of the Proposed Final Net Tangible
Asset Amount, Newco shall notify Lockheed Martin of its objections within 45
days after receipt of Lockheed Martin's calculation of the Proposed Final Net
Tangible Asset Amount and shall set forth, in writing and reasonable detail,
the reasons for Newco's objections. If Newco fails to deliver such notice of
objections within such time, Newco shall be deemed to have accepted Lockheed
Martin's calculation. Lockheed Martin and Newco shall endeavor in good faith to
resolve any disputed items within 20 days after Lockheed Martin's receipt of
Newco's notice of objections. If they are unable to do so, Lockheed Martin and
Newco shall select a nationally known independent accounting firm (other than
Ernst & Young LLP or Coopers & Lybrand L.L.P.) to resolve the dispute (in a
manner consistent with Section 2.03(c) and with any items not in dispute), and
the determination of such firm in respect of the correctness of each item
remaining in dispute shall be conclusive and binding on Lockheed Martin and
Newco. The Net Tangible Assets of the Business as of the close of business on
the Effective Date as finally determined pursuant to this Section 2.03(b)
(whether by failure of Newco to deliver notice of objection, by agreement of
Lockheed Martin and Newco or by determination of the accountants selected as
set forth above) is referred to herein as the "Final Net Tangible Asset
Amount."

     (c) The Estimated Final Net Tangible Asset Amount, the Proposed Final Net
Tangible Asset Amount and the Final Net Tangible Asset Amount shall be
determined in accordance with the accounting principles, policies, practices
and methods utilized in the preparation of the December Statement, as disclosed
in the notes to the December Statement, except as otherwise set forth in
Attachment VI.

     (d) If the Final Net Tangible Asset Amount is greater than the Estimated
Final Net Tangible Asset Amount, the difference shall be paid to Lockheed
Martin by Newco with interest thereon from the Closing Date to the date of
payment at a rate per annum equal to the per annum interest rate announced from
time to time by Bank of America National Trust and Savings Association as its
reference rate in effect. If the Final Net Tangible Asset Amount is less than
the Estimated Final Net Tangible Asset Amount, the difference shall be paid to
Newco by Lockheed Martin with interest thereon from the Closing Date to the
date of payment at a rate per annum equal to the per annum interest rate
announced from time to time by Bank of America National Trust and Savings
Association as its reference rate in effect. Such payment shall be made in
immediately available funds not later than five Business Days after the
determination of the Final Net Tangible Asset Amount by wire transfer to a bank
account designated in writing by the party entitled to receive the payment;
provided, however, if Newco is prohibited from making such payment by the
financing arrangements of Newco in effect as of the Closing Date, then, in lieu
of making any payment in excess of the sum of (i) the difference between
$479,835,000 and the amount of the payment actually made pursuant to Section
2.04(i) and (ii) $5,000,000 by wire transfer in immediately available funds,
Newco may deliver to Lockheed Martin in satisfaction of its obligation in
excess of such sum a subordinated note

                                       11

<PAGE>

the principal amount of which shall equal such excess and providing for
repayment thereof in eight consecutive equal quarterly payments of principal
together with interest thereon, with an interest rate and such other terms and
conditions that reflect the financial condition of Newco and would be available
to Newco for similar subordinated debt on the date the subordinated note is
delivered to Lockheed Martin by Newco, which subordinated note is to be
negotiated by the parties in good faith in the event such subordinated note is
required to be issued pursuant to the terms hereof.

     (e) Lockheed Martin shall make available and shall cause Ernst & Young LLP
to make available, in accordance with reasonable and customary practices and
professional standards and subject to such reasonable conditions as Ernst &
Young LLP shall impose, the books, records, documents and work papers
underlying the preparation and audit of the December Statement and the
calculation of the Proposed Final Net Tangible Asset Amount. Newco and the
Purchasers shall make available and shall cause Coopers & Lybrand L.L.P. to
make available, in accordance with reasonable and customary practices and
professional standards and subject to such reasonable conditions as Coopers &
Lybrand L.L.P. shall impose, the books, records, documents and work papers
created or prepared by or for Newco in connection with the review of the
Proposed Final Net Tangible Asset Amount and the other matters contemplated by
Section 2.03(b).

     (f) The fees and expenses, if any, of the accounting firm selected to
resolve any disputes between Lockheed Martin and Newco in accordance with
Section 2.03(b) shall be paid one-half by Lockheed Martin and one-half by
Newco.

     Section 2.04 Closing. The closing (the "Closing") of the Contemplated
Transactions shall take place at the offices of Simpson Thacher & Bartlett, 425
Lexington Avenue, New York, New York on April 25, 1997, provided, however, that
if all of the conditions to Closing set forth in Article XII have not been
satisfied (or waived) as of that date and if closing on that date therefore
would be impractical, the Closing shall take place on the fifth Business Day
following the satisfaction or waiver (by the party entitled to waive the
condition) of all conditions to the Closing set forth in Article XII, or at
such other time and place as the parties to this Agreement may agree. The
Closing will occur at 9:00 a.m. on the Closing Date. At the Closing, among
other things:

          (i) Newco shall pay and deliver to Lockheed Martin, for its own
     account and as agent for the Affiliated Transferors, $479,835,000 (minus
     the difference between the Estimated Final Net Tangible Asset Amount and
     $269,118,000 in the event the Estimated Final Net Tangible Asset Amount is
     less than $269,118,000) in immediately available funds by wire transfer to
     an account designated by Lockheed Martin (which account shall be
     designated by Lockheed Martin by written notice to Newco at least two
     Business Days prior to the Closing Date, or such shorter notice as Newco
     shall agree to accept);

         (ii) Newco shall issue to Lockheed Martin, for its own account and as
     agent for the Affiliated Transferors, 6,980,000 shares of Newco Class A
     Stock;

        (iii) Newco shall issue to Lehman 10,020,000 shares of Newco Class A
     Stock in exchange for Lehman paying and delivering to Newco $64,835,000 in
     immediately available funds by wire transfer to an account designated

                                       12

<PAGE>

     by Newco (which account shall be designated by Newco by written notice to
     Lehman at least two Business Days prior to the Closing Date, or such
     shorter notice as Lehman shall agree to accept);

         (iv) Newco shall issue to Lanza 1,500,000 shares of Newco Class B
     Stock in exchange for Lanza paying and delivering to Newco $7,500,000 in
     immediately available funds by wire transfer to an account designated by
     Newco (which account shall be designated by Newco by written notice to
     Lanza at least two Business Days prior to the Closing Date, or such
     shorter notice as Lanza shall agree to accept); and

          (v) Newco shall issue to LaPenta 1,500,000 shares of Newco Class B
     Stock in exchange for LaPenta paying and delivering to Newco $7,500,000 in
     immediately available funds by wire transfer to an account designated by
     Newco (which account shall be designated by Newco by written notice to
     LaPenta at least two Business Days prior to the Closing Date, or such
     shorter notice as LaPenta shall agree to accept).

     Section 2.05 Cash True-Up. Within fifteen Business Days after the Closing
Date, Lockheed Martin shall prepare and deliver to Newco a schedule setting
forth, on a daily basis, the cash generated by the Business from 12:01 a.m. on
the first day following the Effective Date (after subtracting any cash
investments made by any of the Lockheed Martin Companies in or for the benefit
of the Business after the Effective Date and the amount of any checks drawn on
the accounts of any of the Lockheed Martin Companies prior to Closing Date but
not yet debited from such accounts as of the close of business on the day prior
to the Closing Date). Within five Business Days of receipt of the foregoing
schedule, Newco shall make payment to Lockheed Martin if the schedule shows a
net cash usage by the Business during the period referenced in the preceding
sentence and Lockheed Martin shall make payment to Newco if the schedule shows
net cash generation during such period in an amount equal to such net cash
usage or net cash generation, as the case may be. Lockheed Martin shall give
Newco reasonable access to its books and records for the purpose of confirming
the calculations of Lockheed Martin pursuant to this Section 2.05. Any payment
made hereunder shall be made in immediately available funds by wire transfer to
a bank account designated in writing by the party entitled to receive the
payment.

     held or used by any of the Lockheed Martin Companies on the Closing Date;

        (iii) amend, modify, or terminate any Contract where the effect of such
     amendment, modification or termination would be a decrease in the backlog
     value of the relevant Contract or a decrease in the payments to be
     received or made by Newco, in any such case by $250,000 or more;

         (iv) submit any Bid which, if accepted, would result in a fixed price
     Contract that would constitute a Transferred Asset with a backlog value in
     excess of (1) $5,000,000 in the case of a fixed price

                                       14

     Effect on the Business;

       (viii) settle any lawsuit or claim if such settlement imposes a material
     continuing non-monetary obligation on the Business or any of the
     Transferred Assets;

     Section 7.02   Access to Information; Confidentiality.

     (a) Except as may be necessary to comply with any Applicable Laws
(including, without limitation, any requirements with respect to security
clearances) and subject to any applicable privileges (including, without
limitation, the attorney-client privilege), from the date of this Agreement
until the Closing Date, Lockheed Martin will (a) give the Purchasers and their
Representatives reasonable access to the records of the Lockheed Martin
Companies relating to the Business during normal business hours and upon
reasonable prior notice, (b) give the Purchasers and their Representatives
reasonable access to any facilities the possession of which will be transferred
to Newco at Closing during normal business hours and upon reasonable prior
notice for the purpose of Purchasers' conduct of a Phase I Environmental Audit
of such facilities or documentary diligence, (c) furnish to the Purchasers and
their Representatives such financial and operating data and other information
relating to the Business as the Purchasers may reasonably request and (d)
instruct the employees and Representatives of the Lockheed Martin Companies to
cooperate with the Purchasers in their investigation of the Business. Without
limiting the generality of the foregoing, subject to the limitations set forth
in the first sentence of this Section 7.02(a), (i) Lockheed Martin shall use
reasonable commercial efforts to enable the Purchasers and the Purchasers'
Representatives to conduct, at the Purchasers' own expense, business and
financial reviews, investigations and studies as to the operation of the
various Business Units, including any tax, operating or other efficiencies that
may be achieved and (ii) from the date of this Agreement to the Closing Date,
Lockheed Martin shall give the Purchasers and their Representatives access to
information relating to the Business of the type, and with the same level of
detail, as in the ordinary course of business is made available to the
presidents or chief financial officers of the Business Units. Notwithstanding
the foregoing, the Purchasers shall not have access to personnel records of any
of the Lockheed Martin Companies relating to individual performance or
evaluation records, medical histories or other information which in Lockheed
Martin's good faith opinion is sensitive or the disclosure of which could
subject any of the Lockheed Martin Companies to risk of liability.

     (b) For a period of three years after the Closing Date, the Lockheed
Martin Companies will treat and hold as such, any confidential information
concerning the operations or affairs of the Business. In the event any of the
Lockheed Martin Companies is requested or required (by oral or written request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand or similar process or by Applicable Law) to disclose
any such confidential information, then Lockheed Martin will notify Newco
promptly of the request or requirement so that Newco, at its expense, may seek
an appropriate protective order or waive compliance with this Section 7.02(b).
If, in the absence of a protective order or receipt of a waiver hereunder, any
of the Lockheed Martin Companies is, on the advice of counsel, compelled to
disclose such confidential information the Lockheed Martin Company may so
disclose the confidential information, provided that the Lockheed Martin
Company will use its reasonable efforts to obtain reliable assurance that
confidential treatment will be accorded to such confidential information. The
provisions of this Section 7.02(b) will not be deemed to prohibit the
disclosure of confidential information concerning the operations or affairs of
the Business by any of the Lockheed Martin Companies to the extent reasonably
required (i) to prepare or complete any required tax returns or financial
statements, (ii) in connection with audits or other proceedings by or on behalf
of a Governmental Authority, (iii) in connection

                                       16

<PAGE>

with any insurance or benefits claims, (iv) to the extent necessary to comply
with any Applicable Laws, (v) to provide services to Newco in accordance with
the Interim Services Agreement, or (vi) in connection with any other similar
administrative functions in the ordinary course of business. Notwithstanding
the foregoing, the provisions of this Section 7.02(b) shall not apply to
information that (i) is or becomes publicly available other than as a result of
a disclosure by any of the Lockheed Martin Companies, (ii) is or becomes
available to a Lockheed Martin Company on a non-confidential basis from a
source that, to Lockheed Martin's knowledge, is not prohibited from disclosing
such information by a legal, contractual or fiduciary obligation, or (iii) is
or has been independently developed by a Lockheed Martin Company (other than
solely for the Business or by one of the Business Units). This Section 7.02(b)
shall not apply to the disclosure of confidential information concerning the
Instrumentation Recorder Product Line of Advanced Recorders in connection with
or after the sale thereof to a purchaser or potential purchaser (other than
Newco); provided, however, that such disclosure may only be made pursuant to a
confidentiality agreement containing reasonable terms and conditions.

     Section 7.03 Non-Solicitation of Offers. From the date of this Agreement
to the earlier of the Closing Date or the termination of this Agreement,
Lockheed Martin shall not, and Lockheed Martin shall not authorize or permit
any of its Representatives to, directly or indirectly (through Affiliates or
otherwise), (i) solicit, initiate or take any action knowingly to facilitate
the submission of inquiries, proposals or offers from any Person (other than
Newco) relating to any acquisition or purchase of all or a substantial part of
the Business, in one transaction or a series of related transactions (whether
by asset or stock sale, business combination transaction or otherwise),
(collectively, the "Alternative Transaction Proposals"), or (ii) enter into or
participate in any discussions or negotiations regarding any of the foregoing,
or furnish to any other Person any information with respect to the Business
(other than in the ordinary course of operating the Business and in connection
with the possible sale of the Instrumentation Recorder Product Line of Advanced
Recorders) or otherwise cooperate in any way with, or assist or participate in,
facilitate or encourage, any effort or attempt by any other Person to do or
seek any of the foregoing. Except to the extent that it is prohibited from
doing so by contractual agreements that were in existence as of January 31,
1997 (of which there are two), if Lockheed Martin, directly or indirectly,
receives an Alternative Transaction Proposal, Lockheed Martin shall promptly
inform the Purchasers of the terms and conditions of the Alternative
Transaction Proposal and the identity of the Person making it.

     Section 7.04 Non-Solicitation of Employees. From and after the date of
this Agreement until the second anniversary of the Closing Date, Lockheed
Martin shall not, without prior written approval of Newco, directly or
indirectly (through Affiliates or otherwise), knowingly solicit any individual
(other than individuals identified in Attachment XI) who at that time is an
employee of the Business to terminate his or her relationship with the Business
and will not knowingly hire any individual inadvertently solicited; provided,
however, that the foregoing shall not apply to (i) individuals solicited or
hired as a result of the use of an independent employment agency (so long as
the agency was not directed to solicit such individual and Lockheed Martin,
promptly following execution of this Agreement, advises the Vice President for
Human Resources of each Operating Sector of Lockheed Martin of the provisions
of this Section 7.04), and (ii) individuals solicited or hired as a result of
the use of a general

                                       17

<PAGE>

solicitation  (such   as  an  advertisement)  not   specifically  directed  to
employees of the Business.

     Section 7.05 Change of Lockbox Accounts. Immediately after the Closing,
Lockheed Martin shall take such steps as Newco may reasonably request to cause
Newco to be substituted as the sole party having control over any lockbox or
similar bank account maintained exclusively by the Business Units to which
customers of the Business directly make payments in respect of the Business or
to direct the bank at which any such lockbox or similar account is maintained
to transfer any payments made thereto to an account established by Newco.

     Section 7.06 Access to Information; Cooperation After Closing. On and
after the Closing Date and subject to any applicable privileges (including,
without limitation, the attorney-client privilege), Lockheed Martin shall, and
shall cause each of the other Lockheed Martin Companies to, at their expense
(i) afford Newco and its Representatives reasonable access upon reasonable
prior notice during normal business hours, to all employees, offices,
properties, agreements, records, books and affairs of the Lockheed Martin
Companies to the extent relating to the Business, (ii) provide copies of such

proper purpose, including, without limitation, in connection with any public or
private offering of securities by Newco or the preparation of any financial
statements or in connection with any judicial, quasi judicial, administrative,
or arbitration proceeding or audit (provided, however, that except as otherwise
provided in writing signed by an officer of Lockheed Martin specifically
approving the use of such information, the specific purpose for which such
information is to be used therein and the specific representations and
warranties at issue, Lockheed Martin makes no representations or warranties to
the Purchasers, Newco or any other Person in respect of any such information)
and (iii) cooperate fully with Newco for any proper purpose, including, without
limitation, in the defense or pursuit of any Transferred Asset, Assumed
Liability or any claim or action that relates to occurrences involving the
Business prior to the Closing Date.

     Section 7.07 Maintenance of Insurance Policies. Except as otherwise
provided in Exhibit G, on and after the date of this Agreement and until the
Closing Date, Lockheed Martin shall not take or fail to take any action if such
action or inaction, as the case may be, would adversely affect the
applicability of any insurance (including reinsurance) in effect on the date of
this Agreement that covers all or any part of the assets that would constitute
Transferred Assets if owned, held or used by any of the Lockheed Martin
Companies on the Closing Date, the Business or the Transferred Employees.
Except as otherwise provided in Exhibit G or as may otherwise be agreed in
writing by the parties, Lockheed Martin shall not have any obligation to
maintain the effectiveness of any such insurance policy after the Closing Date
or to make any monetary payment in connection with any such policy.

     Section 7.08 Novation of Government Contracts. As soon as is reasonably
practicable following the Closing, Lockheed Martin shall, in accordance with
Federal Acquisition Regulations Part 42, Section 42.12, submit in writing to
each Responsible Contracting Officer (as such term is defined in Federal
Acquisition Regulations Part 42, Section 42.102(a)), a request for the U.S.
Government to (i) recognize Newco as the successor in interest to all of the
Government Contracts being sold, assigned, transferred and conveyed to Newco in
accordance with this Agreement and (ii) enter into a

                                       18

<PAGE>

novation agreement (the "Novation Agreement") substantially in the form
contemplated by such regulations. Lockheed Martin shall use commercially
reasonable efforts to obtain all consents, approvals and waivers required for
the purpose of processing, entering into and completing the Novation Agreement
with regard to any of the Government Contracts, including responding to any
reasonable requests for information by the U.S. Government with regard to such
Novation Agreement.

     Section 7.09 Financial Statements. Lockheed Martin shall, at Lockheed
Martin's expense, furnish and shall cause its independent accountants for the
Communications Systems Business Unit to audit and furnish their opinion thereon
not later than March 28, 1997, financial statements for such Business Unit for
the years ended December 31, 1996, December 31, 1995 and December 31, 1994
prepared in accordance with GAAP applied consistently throughout the periods
covered thereby in a form meeting the requirements of Regulation S-X of the
Securities Act, and, consistent with appropriate terms and conditions and upon
receipt of appropriate management representation letters, to furnish the
consent of such independent accountants to the inclusion of their report on
such financial statements to the extent the financial statements are required
to be included in any registration statement of Newco under the Securities Act
and any amendments thereto or in any offering memoranda in connection with an
offering of securities exempt from registration under the Securities Act, and
to provide comfort letters in customary form in connection therewith; and for
the purposes of assisting Newco with any such registration statement and
subsequent reporting requirements under the Securities Act of 1934, as amended,
Lockheed Martin will deliver to Newco unaudited income statements and balance
sheets of the Communications Systems Business Unit for each 1996 calendar
quarter and each 1997 calendar quarter completed prior to or on the Closing
Date. The financial statements and schedules described in the preceding
sentence for the first quarter of 1997 and 1996, respectively, will be provided
by May 10, 1997. To the extent required, each subsequent 1997 quarter's
financial statements and schedules (together with the corresponding 1996
quarter's financial statements) shall be delivered to Newco by Lockheed Martin
within 40 days after the last day of such quarter. The parties acknowledge and
agree that time is of the essence in the performance of this Section 7.09 and
Lockheed Martin shall provide Newco unaudited financial information with
respect to the Communications Systems Business Unit for the years 1993 and 1992
meeting the requirements of Item 301 of Regulation S-K (Selected Financial
Data) of the Securities Act by April 4, 1997. Lockheed Martin acknowledges that
Newco's independent accountants will be performing the audit of the combined
financial statements of the Business for the year ended December 31, 1996 (and,
if required by applicable SEC regulations, for the period from January 1, 1997
to the Closing Date), and the combined financial statements of the Wideband
Systems Business Unit and the Products Group of the Business for the three
months ended March 31, 1996 and the years ended December 31, 1995 and December
31, 1994. Lockheed Martin agrees to cooperate and cause its independent
accountants to cooperate with Newco's independent accountants, and provide such
reasonable representation letters of Lockheed Martin's management to Newco's
independent accountants in a form appropriate to enable such accountants to
issue an opinion on the financial statements they are auditing in accordance
with professional standards.

                                 ARTICLE VIII

                     COVENANTS OF NEWCO AND THE PURCHASERS

     Section 8.01   Confidentiality.

     (a) Newco and the Purchasers agree that all information provided or
otherwise made available in connection with the Contemplated Transactions, to
any of the Purchasers, Newco or their Representatives will be treated as if
provided, in the case of Newco and Lehman, under the Lehman Confidentiality
Agreement (whether or not the Lehman Confidentiality Agreement is in effect or
has been terminated) or, in the case of the Individual Purchasers, under
paragraph 7 of the Memorandum (whether or not the Memorandum is in effect or
has been terminated). In addition, until consummation of the Closing, Newco
agrees to be bound by the terms of the Lehman Confidentiality Agreement as if
Newco were Lehman thereunder (whether or not the Lehman Confidentiality
Agreement is in effect or has been terminated). Upon consummation of the
Closing, the Lehman Confidentiality Agreement and paragraph 7 of the Memorandum
shall cease to apply.

     (b) For a period of three years after the Closing Date, the Purchasers,
Newco and each of their Affiliates will treat and hold as such, any
confidential information concerning the operations or affairs of businesses of
the Lockheed Martin Companies (other than the Business). In the event that any
of the Purchasers, Newco or any of their Affiliates is requested or required
(by oral or written request for information or documents in any legal
proceeding, interrogatory, subpoena, civil investigative demand or similar
process or by Applicable Law) to disclose any such confidential information,
then they will notify Lockheed Martin promptly of the request or requirement so
that Lockheed Martin, at its expense, may seek an appropriate protective order
or waive compliance with this Section 8.01(b). If, in the absence of a
protective order or receipt of a waiver hereunder, any of the Purchasers, Newco
or any of their Affiliates is, on the advice of counsel, compelled to disclose
such confidential information, they may so disclose the confidential
information, provided that they use reasonable efforts to obtain reliable
assurance that confidential treatment will be accorded to such confidential
information. Notwithstanding the foregoing, the provisions of this Section
8.01(b) shall not apply to information that (i) is or becomes publicly
available other than as a result of a disclosure by any of the Purchasers,
Newco or any of their Affiliates, (ii) is or becomes available to any of the
Purchasers, Newco or any of their Affiliates on a non-confidential basis from a
source that, to the Purchasers', Newco's or any of their Affiliates' knowledge,
is not prohibited from disclosing such information by a legal, contractual or
fiduciary obligation, or (iii) is or has been independently developed by any of
the Purchasers, Newco or any of their Affiliates.

     (c) Nothing in this Section 8.01 shall abrogate or otherwise limit the
fiduciary duties of, and any other duties or restrictions imposed by Applicable
Law on, the Individual Purchasers by virtue of their service as a director,
officer or employee of any of the Lockheed Martin Companies or their
predecessors.

                                       20

<PAGE>

     Section 8.02   Provision  and  Preservation  of  and  Access  to  Certain
Information; Cooperation.

     (a) Prior to the Closing Date, each Purchaser shall provide to Lockheed
Martin promptly upon its receipt thereof copies of all environmental audit and
similar reports with respect to facilities the possession of which will be
transferred to Newco at the Closing.

     (b) The Individual Purchasers acknowledge that effective as of February 3,
1997, Lockheed Martin turned over day-to-day management of the Business Units
to the Individual Purchasers. From the date of this Agreement until the Closing
Date, the Individual Purchasers agree to take reasonable steps to ensure that
the Business Units conduct their business and operations in accordance with the
provisions of Section 7.01. Notwithstanding the foregoing, the Individual
Purchasers shall not have liability to any Person for the breach of this
Section 8.02(b), it being understood that the effects of a breach of this
Section 8.02(b) shall be limited to the effects set forth in Section 13.04(d)
and Section 14.02.

     (c) On and after the Closing Date, Newco shall preserve all books and
records of the Business for a period of five years commencing on the Closing
Date (or in the case of books and records relating to tax, employment and
employee benefits matters, until such time as Lockheed Martin notifies Newco in
writing that all statutes of limitations to which such records relate have
expired), and thereafter, not to destroy or dispose of such records without
giving notice to Lockheed Martin of such pending disposal and offering Lockheed
Martin the right to copy such records at its expense. In the event Lockheed
Martin has not copied such materials within 90 days following the receipt of
notice from Newco, Newco may proceed to destroy or dispose of such materials
without any liability. From and after the Closing Date and subject to any
applicable privileges (including, without limitation, the attorney-client
privilege), Newco shall at its expense (i) afford Lockheed Martin and its
Representatives reasonable access upon reasonable prior notice during normal
business hours, to all employees, offices, properties, agreements, records,
books and affairs of Newco, and provide copies of such information concerning
the Business as Lockheed Martin may reasonably request for any proper purpose,
including, without limitation, in connection with the preparation of any tax
returns or financial statements or in connection with any judicial, quasi
judicial, administrative, tax, audit or arbitration proceeding and in
connection with the preparation of any financial statements or reports in
accordance with past practices and procedures and (ii) cooperate fully with
Lockheed Martin for any proper purpose, including, without limitation, the
defense of or pursuit of any Excluded Liability, Excluded Asset or any claim or
action that relates to an Excluded Liability or Excluded Asset.

     Section 8.03   Insurance; Financial Support Arrangements.

     (a) Newco and the Purchasers acknowledge and agree that as of the Closing
Date, neither Newco, the Business or any of the Business Units, any property
owned or leased by any of the foregoing nor any of the directors, officers,
employees (including, without limitation, the Transferred Employees) or agents
of any of the foregoing will be insured under any insurance policies maintained
by Lockheed Martin or any of its Affiliates, except (i) in the case of certain
policies, to the extent that a claim has been reported as of the Closing Date,
(ii) in the case of a policy that is an occurrence policy, to the extent the
accident, event or occurrence that

                                       21

<PAGE>

results in an insurable loss occurs prior to the Closing Date and has been, is
or will be reported or noticed to the respective carrier by Newco or any of the
Lockheed Martin Companies in accordance with the requirements of such policies
(which claims Lockheed Martin shall, at Newco's cost and expense, pursue
diligently on Newco's behalf and the net proceeds of which claims shall be
remitted promptly to Newco upon receipt thereof), and (iii) as otherwise
provided in Exhibit G or agreed to in writing by the parties. Except as
otherwise provided in Exhibit G or as otherwise may be agreed to in writing by
the parties, from and after the Closing Date, Lockheed Martin shall have no
obligation of any kind to maintain any form of insurance covering all or any
part of the Transferred Assets, the Business or the Transferred Employees.

     (b) Newco agrees to reimburse Lockheed Martin within 30 days of receipt of
an invoice for the items set forth below.

          (i) The allocated cost to the Business of premiums, costs and
     expenses (excluding Lockheed Martin risk management department costs and
     expenses), including general and administrative charges, for all periods
     prior to the Closing Date in respect of any and all insurance policies
     that cover or covered the Business, whether or not a claim has been made
     or ever will be made by the Business or Newco under such policies. The
     "allocated cost" to the Business shall be determined by Lockheed Martin in
     a manner consistent with prior practices and in conjunction with the Cost
     Disclosure Statement filed by Lockheed Martin or any of its Affiliates and
     their predecessors with the U.S. Government on the portion of the period
     covered by the respective policies that ends prior to the Closing Date,
     except that with respect to policies for which no premium rebate or refund
     is available as a result of the consummation of the Contemplated
     Transactions, the "allocated cost" to the Business shall be based on the
     entire policy period. Newco and the Purchasers understand that Lockheed
     Martin is in the process of reviewing with the U.S. Government the
     methodology used by Lockheed Martin and its Affiliates to allocate
     premiums, costs, expenses and reserves to various businesses and
     divisions, including the Business Units, and acknowledge that any changes
     to such allocation methodology may result in retroactive adjustments to
     the allocated cost to the Business of premiums, costs and expenses. In the
     event of any such change to the allocation methodology, Lockheed Martin
     and Newco agree to adjust the allocated costs to the Business (either
     through a special charge or credit to Newco under this Section 8.03(b)(i))
     as appropriate.

         (ii) Any self insurance, retention, deductible, retrospective premium,
     cash payment for reserves calculated or charged on an incurred loss basis
     and similar items, including but not limited to associated administrative
     expenses and allocated loss adjustment or similar expenses (collectively,
     "Insurance Liabilities") allocated to the Business by Lockheed Martin on a
     basis consistent with past practices resulting from or arising under any
     and all current or former insurance policies maintained by Lockheed Martin
     or any of its Affiliates to the extent that such Insurance Liabilities
     relate to or arise out of the Business or any activities of Newco.

Newco agrees that, to the extent any of the insurers under the insurance
policies, in accordance with the terms of the insurance policies, requests or
requires collateral, deposits or other security to be provided with respect to
claims made against such insurance policies relating to or arising from

                                       22

<PAGE>

the Business, Newco will provide the collateral, deposits or other security or,
upon request of Lockheed Martin, will replace any collateral, deposits or other
security provided by Lockheed Martin or any of its Affiliates.

     (c) Newco agrees that, for a period of at least six years commencing on
the Closing Date, to the extent it maintains insurance coverage, Newco will (at
Lockheed Martin's cost to the extent of any additional cost therefor, provided
that, in the event there will be such a cost, Newco will give Lockheed Martin a
reasonable period of time to determine whether it desires to incur such cost
before Newco commits to such coverage with respect to Lockheed Martin) include
Lockheed Martin and its Affiliates as an additional insured/loss payee on any
policies in respect of which Lockheed Martin or its Affiliates has or may have
an insurable interest with respect to the Business, the Transferred Assets, any
of the Assumed Liabilities or any facilities the possession of which will be
transferred to Newco at the Closing.

     (d) Newco and the Purchasers agree that, not later than September 30,
1997, and in a manner reasonably satisfactory to Lockheed Martin, Newco will in
good faith seek to release Lockheed Martin and its Affiliates from all
obligations under all Financial Support Arrangements maintained by Lockheed
Martin or any of its Affiliates in connection with the Business.

     (e) Lockheed Martin will use reasonable commercial efforts to cause each
Financial Support Arrangement to remain in full force and effect in accordance
with its terms until the earliest of (i) the date (the "Release Date") on which
Newco ensures that Lockheed and its Affiliates are released from all
obligations of Lockheed Martin and its Affiliates under such Financial Support
Arrangement in accordance with Section 8.03(d), (ii) September 30, 1997 and
(iii) the date such Financial Support Arrangement terminates in accordance with
its terms. After the Closing Date and prior to the Release Date for any such
Financial Support Arrangement, Lockheed Martin will not waive any requirements
of or agree to amend such Financial Support Arrangement without the prior
written consent of Newco.

     (f) If, after the Closing Date, (i) any amounts are drawn on or paid under
any Financial Support Arrangement where Lockheed Martin or any of its
Affiliates is obligated to reimburse the Person making such payment or (ii)
Lockheed Martin or any of its Affiliates pays any amounts under, or any fees,
costs or expenses relating to, any Financial Support Arrangement, Newco shall
pay Lockheed Martin such amounts promptly after receipt from Lockheed Martin of
notice thereof accompanied by written evidence of the underlying payment
obligation.

     (g) In the event that Newco fails to ensure that Lockheed Martin and its
Affiliates are released from all obligations under the Financial Support
Arrangements not later than September 30, 1997, Newco shall either (i) promptly
deposit with Lockheed Martin cash in an amount equal to the aggregate principal
or stated amount, as may be applicable, of the Financial Support Arrangements
not so released or (ii) provide back-up letters of credit in form and substance
reasonably satisfactory to Lockheed Martin with respect to such Financial
Support Arrangements; provided that if Newco has used reasonable commercial
efforts to structure its financing arrangements to permit it to comply with the
foregoing obligations, Newco shall not be required to take any action under
this Section 8.03(g) that it is prohibited from taking under the terms of any
financing agreements of Newco in effect on the Closing Date. Any cash deposited
with Lockheed Martin in accordance with

                                       23

<PAGE>

clause (i) shall be held by Lockheed Martin in a segregated interest-bearing
account and shall be used by Lockheed Martin solely to satisfy its payment
obligations in respect of such Financial Support Arrangements, and the unused
portion of any cash (including interest) relating to a Financial Support
Arrangement shall be returned to Newco promptly after the occurrence of the
Release Date with respect to, or any other termination of, the Financial
Support Arrangement.

     (h) In the event that Newco fails to ensure that Lockheed Martin and its
Affiliates are released from all obligations of Lockheed Martin and its
Affiliates under the Disclosed Financial Support Arrangements not later than
September 30, 1997, whether as a result of the proviso to the first sentence of
Section 8.03(g) or otherwise, and to the extent that Newco has not provided the
deposits or letters of credit contemplated by the first sentence of Section
8.03(g), on October 1, 1997 and on the first day of each calendar quarter
thereafter Newco agrees to pay to Lockheed Martin an amount equal to (i) .3125%
of the maximum aggregate potential liability of Lockheed Martin and its
Affiliates under such Disclosed Financial Support Arrangements in the case of
performance-related Disclosed Financial Support Arrangements or (ii) .625% of
the maximum aggregate potential liability of Lockheed Martin and its Affiliates
under such Disclosed Financial Support Arrangements in the case of all other
Disclosed Financial Support Arrangements (other than Disclosed Financial
Support Arrangements that constitute non-monetary performance guarantees or
similar non-monetary obligations) that have not been released or otherwise
secured by the deposits or letters of credit contemplated by the first sentence
of Section 8.03(g) (determined as of the last day of the preceding calendar
quarter). Any such payment by Newco shall be due and payable on October 1, 1997
or on the first day of the applicable calendar month thereafter, and shall be
nonrefundable regardless of any subsequent reduction of the liability of
Lockheed Martin or any of its Affiliates thereunder.

     Section 8.04 Non-Solicitation of Employees. From and after the date of
this Agreement until the second anniversary of the Closing Date, Newco shall
not, without prior written approval of Lockheed Martin, directly or indirectly
(through Affiliates or otherwise), knowingly solicit any individual (other than
individuals identified in Attachment XI) who at that time is an employee of any
of the Lockheed Martin Companies (other than a Transferred Employee) to
terminate his or her relationship with the Lockheed Martin Companies and will
not knowingly hire any individual inadvertently solicited; provided, however,
that the foregoing shall not apply to individuals solicited or hired as a
result of the use of an independent employment agency (so long as the agency
was not directed to solicit such individual and Newco advises its Manager of
Human Resources of the provisions of this Section 8.04) or solicited or hired
as a result of the use of a general solicitation (such as an advertisement) not
specifically directed to employees of the Lockheed Martin Companies.

     Section 8.05 Financing. Newco shall use reasonable commercial efforts to
obtain (on or prior to the Closing Date) sufficient funds on commercially
available terms acceptable to Newco in its sole discretion (i) to pay the cash
portion of the Exchange Consideration and (ii) to obtain adequate working
capital for the Business, provided that Newco shall not be considered to be in
breach of this Agreement if, notwithstanding its use of reasonable commercial
efforts as aforesaid, Newco does not have sufficient funds available for such
purposes on the Closing Date.

that it is not obtaining any rights or licenses with respect to the names
"Lockheed Martin," "Lockheed," "Loral," "Martin Marietta" or any derivative
thereof, or to their logos or trade dress, or to any other Intellectual
Property not constituting a Transferred Asset or not licensed to it under the
License Agreements. As soon as practicable following the Closing, but no later
than 180 days after the Closing Date, Newco shall remove and change signage,
change and substitute promotional and advertising material in whatever medium,
change stationery and packaging and take all such other steps as may be
required or appropriate to cease use of all such Intellectual Property not
constituting a Transferred Asset or not licensed to it under the License
Agreements; provided, however, that nothing in this Agreement shall obligate
Newco to change or copy over any engineering drawings, prints or copies of
correspondence, invoices and other documents prepared prior to the Closing Date
or to replace or alter any tools or dies included in the Transferred Assets.

     Section 8.07 Government Contract Novation; Cooperation. Newco shall
provide to Lockheed Martin and each Responsible Contracting Officer all
information necessary to obtain the consent of the U.S. Government to recognize
Newco as the successor in interest to all of the Government Contracts being
sold, assigned, transferred and conveyed to Newco in accordance with this
Agreement. Newco shall use commercially reasonable efforts to obtain all
consents, approvals and waivers required for the purpose of processing,
entering into and completing the Novation Agreement with regard to any of the
Government Contracts, including responding to any requests for information by
the U.S. Government with regard to such Novation Agreement.

     Section 8.08 Reimbursement of Damages. Newco shall use reasonable
commercial efforts to obtain reimbursement of any Damages suffered by it that
are subject to indemnification by Lockheed Martin hereunder as a reimbursable
cost under Government Contracts, provided the reimbursement of such Damages is
permitted by Applicable Law.

this Agreement, each party shall use all reasonable commercial efforts to take,
or cause to be taken, all actions and to do, or cause to be done, all things
necessary or desirable under Applicable Laws to consummate the Contemplated
Transactions. Lockheed Martin, Newco and the Purchasers shall execute and
deliver such other documents, certificates, agreements and other writings and
to take such other actions as may be necessary or desirable in order to
consummate or implement expeditiously the Contemplated Transactions. Except as
otherwise expressly set forth in the Transaction Documents, nothing in this

desirable in connection with the consummation of the Contemplated Transactions.

     Section 9.02   Certain  Filings; Consents.   Lockheed  Martin,  Newco and

Government as a customer with respect to this Agreement or the Contemplated
Transactions and, except as may be required by Applicable Law or any listing
agreement with any national or international securities exchange, will not

Individual Purchasers from any of their respective obligations under paragraph
7 of the Memorandum, or terminate any of the restrictions imposed upon any
party by Section 8.01.

Property constituting part of the Transferred Assets subject to any licenses
thereof granted by Lockheed Martin and its Affiliates prior to the Closing

     (d) The transfer of Intellectual Property constituting Transferred Assets
to Newco shall not affect Lockheed Martin's right to use, disclose or otherwise
freely deal with any know-how, trade secrets and other technical information
not constituting Transferred Assets that is resident on the Closing Date at
businesses of the Lockheed Martin Companies other than the Business.

     Section 9.05 HSR Act. The parties shall take all actions necessary or

including, without limitation, complying as promptly as practicable with any
requests for additional information; provided that Newco shall not be required
to provide any undertakings or comply with any condition that, in its good
faith judgment, would materially and adversely diminish Newco's rights under
this Agreement or materially and adversely affect its business, results or
operations.

     Section 9.06 Operation of Newco. From and after the date of this Agreement
through the Closing, Newco will not engage in or conduct any activities other
than activities that are necessary or appropriate in connection with the
consummation of the Contemplated Transactions.

     Section 9.07 Maintenance of Insurance Policies. Notwith-standing any
provision to the contrary in this Agreement, this Section 9.07 shall constitute
the parties' agreement regarding the allocation of insurance proceeds with
respect to claims for liabilities that arise under or relate to Environmental
Laws that are comprised, in whole or in part, of Environmental Liabilities that
constitute Assumed Liabilities (the "Environmental Insurance Claims"). Newco
and the Purchasers acknowledge that Lockheed Martin shall control the
Environmental Insurance Claims and shall have the right to compromise or settle
any Environmental Insurance Claims. Lockheed Martin will act in good faith and
with reasonable prudence to maximize recovery with respect to the Environmental
Insurance Claims and will allocate any recovery received with respect to such
Environmental Insurance Claims, first, to the costs it incurred to collect such
recovery and all net tax costs related to such recovery, and second, to
reimburse any Governmental Authority, prime contractor or subcontractor
pursuant to a Government Contract.

     With respect to any recovery remaining (the "Remaining Recovery"):

          (i) if the recovery applies to liabilities that are Assumed
     Liabilities and to liabilities that are not Assumed Liabilities, and the
     recovery was not designated as arising from specific liabilities (e.g., a
     global settlement with an insurance carrier), Lockheed Martin will pay
     Newco an amount equal to the Remaining Recovery multiplied by X multiplied
     by (one minus Y); where X equals the total of the Environmental Insurance
     Claims (estimated as of the date of recovery) under said insurance
     policies divided by the total environmental and other claims by Lockheed
     Martin under said insurance policies; and Y equals Lockheed Martin's past
     expenditures on said liabilities divided by the total estimated
     expenditures made or to be made by Lockheed

                                       27

<PAGE>

     Martin or Newco in respect of said liabilities (estimated as  of the date
     of recovery), or

         (ii) if the recovery was designated as arising from a specific
     liability that is an Assumed Liability, Lockheed Martin will pay Newco the
     Remaining Recovery multiplied by (one minus Y).

     Any obligations assumed in any such compromise or settlement of the
Environmental Insurance Claims will be apportioned between Lockheed Martin and
Newco in the same proportion as a recovery would be allocated pursuant to this
Section 9.07.

     Section 9.08 Legal Privileges. Lockheed Martin and Newco acknowledge and
agree that all attorney-client, work product and other legal privileges that
may exist with respect to the Transferred Assets or the Assumed Liabilities,
shall, from and after the Closing Date, be deemed joint privileges of Lockheed
Martin and Newco. Both Lockheed Martin and Newco shall use all commercially
reasonable efforts after the Closing Date to preserve all such privileges and
neither Lockheed Martin nor Newco shall knowingly waive any such privilege
without the prior written consent of the other party (which consent will not be
unreasonably withheld or delayed).

     Section 9.09 Non-Compete. Lockheed Martin, Newco and the Purchasers
covenant and agree that prior to the Closing Date they will discuss in good
faith the scope and nature of an appropriate non-competition agreement to
provide reasonable commercial protection to Newco for periods to be mutually
agreed upon of up to three years with respect to the material core businesses
of the Business while providing the Lockheed Martin Companies the ability to
continue, without impediment, all of its existing businesses and currently
planned businesses (other than those conducted only through the Business
Units), to enter into businesses reasonably related to its exiting businesses
and currently planned businesses, to make acquisitions and to otherwise provide
third-party sourced products similar to those manufactured or sold by the
Business as part of larger systems manufactured or sold by the Lockheed Martin
Companies. The non-competition agreement also will provide reasonable
commercial protection to the Lockheed Martin Companies on programs where Newco
performs substantial subcontract work for the Lockheed Martin Companies, it
being understood that this provision shall not prohibit Newco from entering
into subcontract agreements with other Persons on programs that compete against
the Lockheed Martin Companies, provided that appropriate safeguards (including,
for example, "firewalls" and confidentiality agreements) are implemented and in
place to protect the proprietary and confidential information of the Lockheed
Martin Companies. For the purposes of any such non-competition agreement, (i)
the businesses operated and managed by Lockheed Martin on behalf of the U.S.
Government, including the Department of Energy, shall not be included within
the prohibitions, and (ii) "currently planned" businesses of the Lockheed
Martin Companies shall mean those businesses that Lockheed Martin can
demonstrate are affirmatively under consideration as of the Closing Date.

     (b) Effective as of the Closing and subject to the limitations set forth
in Section 13.04(b), Lockheed Martin hereby indemnifies Newco and its
Affiliates and their respective directors, officers, employees and agents
against and agrees to hold them harmless from any and all Damages incurred or

to be performed by the Lockheed Martin Companies pursuant to any Transaction
Document, (ii) the Excluded Liabilities (including, without limitation,

related in any way to any breach of any Surviving Representation or Covenant

     Section 13.03  Procedures.

     (a) If Lockheed Martin or any of its Affiliates or any of their directors,
officers, employees and agents, shall seek indemnification pursuant to Section
13.02(a) or Section 13.02(c), or if Newco or any of its Affiliates or any of
their directors, officers, employees and agents, shall seek indemnification
pursuant to Section 13.02(b), such Person seeking indemnification (the
"Indemnified Party") shall give written notice to the party from whom such
indemnification is sought (the "Indemnifying Party") promptly (and in any event
within 30 days) after the Indemnified Party (or, if the Indemnified Party is a
corporation, any officer of the Indemnified Party) becomes aware of the facts
giving rise to such claim for indemnification (an "Indemnified Claim")
specifying in reasonable detail the factual basis of the Indemnified Claim,
stating the amount of the Damages, if known, the method of computation thereof,
and containing a reference to the provision of the Transaction Documents in
respect of which such Indemnified Claim arises. The failure of an Indemnified
Party to provide notice pursuant to this Section 13.03 shall not constitute a
waiver of that party's claims to indemnification pursuant to Section 13.02 in
the absence of, and then only to the extent of, material prejudice to the
Indemnifying Party. If the Indemnified Claim arises from the assertion of any
claim, or the commencement of any suit, action, proceeding or Remedial Action
brought by a Person that is not a party hereto (a "Third Party Claim")any such
notice to the Indemnifying Party shall be accompanied by a copy of any papers
theretofore served on the Indemnified Party in connection with such Third Party
Claim. With respect to any Third Party Claim asserted or brought prior to the
Closing Date, notice of such Third Party Claim shall be deemed to have been
delivered on the Closing Date.

     (b) (i) Upon receipt of notice of a Third Party Claim from an Indemnified
     Party pursuant to Section 13.03(a), the Indemnifying Party will, subject
     to the other provisions of this Section 13.03(b), assume the defense and
     control of such Third Party Claim but shall allow the Indemnified Party a
     reasonable opportunity to participate in the defense thereof with its own
     counsel and at its own expense. The Indemnifying Party shall select
     counsel, contractors and consultants of recognized

                                       33

<PAGE>

     standing and competence after consultation with the Indemnified Party;
     shall take all steps necessary in the defense or settlement thereof; and
     shall at all times diligently and promptly pursue the resolution thereof.
     In conducting the defense thereof, the Indemnifying Party shall at all
     times act as if all Damages relating to such Third Party Claim were for
     its own account and shall act in good faith and with reasonable prudence
     to minimize Damages therefrom. The Indemnified Party shall, and shall
     cause each of its Affiliates, directors, officers, employees, and agents
     to, cooperate fully with the Indemnifying Party in the defense of any
     Third Party Claim defended by the Indemnifying Party.

         (ii) The Indemnifying Party shall give prompt and continuing notice to
     the other Indemnified Party of any Third Party Claims that the
     Indemnifying Party reasonably believes may: (1) result in the assertion of
     criminal liability on the part of the Indemnified Party or any of its
     Affiliates, directors, officers, employees or agents; (2) adversely affect
     the ability of the Indemnified Party to do business in any jurisdiction or
     in any manner or with any customer; or (3) materially affect the
     reputation of the Indemnified Party or any of its Affiliates, directors,
     officers, employees or agents.

        (iii) Subject to the provisions of Section 13.03(b)(iv) and Section
     13.03(b)(v), the Indemnifying Party shall be authorized to consent to a
     settlement of, or the entry of any judgment arising from, any Third Party
     Claims, without the consent of any Indemnified Party; provided, that the
     Indemnifying Party shall (1) pay or cause to be paid all amounts arising
     out of such settlement or judgment concurrently with the effectiveness
     thereof; (2) shall not encumber any of the assets of any Indemnified Party
     or agree to any restriction or condition that would apply to such
     Indemnified Party or to the conduct of that party's business; and (3)
     shall obtain, as a condition of any settlement or other resolution, a
     complete release of each Indemnified Party. Except for the foregoing, no
     settlement or entry of judgment in respect of any Third Party Claim shall
     be consented to by any Indemnifying Party without the consent of the
     Indemnified Party, which consent shall not be unreasonably withheld.

         (iv) An Indemnified Party may elect to share the defense of a Third
     Party Claim the defense of which has been assumed by the Indemnifying
     Party pursuant to Section 13.03(b)(ii). In that event, the Indemnified
     Party will so notify the Indemnifying Party in writing. Thereafter, the
     Indemnifying Party and the Indemnified Party shall participate on an equal
     basis in the defense, management and control of any such claim. The
     Indemnifying Party and the Indemnified Party shall select mutually
     satisfactory counsel, contractors and consultants to conduct the defense
     or settlement thereof (the costs and expenses of which shall be shared
     equally by the Indemnifying Party and the Indemnified Party), and shall at
     all times diligently and promptly pursue the resolution thereof.
     Notwithstanding the foregoing, Newco shall manage all Remedial Actions
     conducted with respect to facilities which constitute Transferred Assets
     or at which Newco will undertake operations pursuant to this Agreement,
     provided that Lockheed Martin and its Representatives shall have the
     right, consistent with Newco's right to manage such Remedial Actions as
     aforesaid, to participate fully in all decisions regarding any Remedial
     Action, including reasonable access to sites where any Remedial Action is
     being conducted, reasonable access to all documents, correspondence,

                                       34

<PAGE>

     data, reports or information regarding the Remedial Action, reasonable
     access to employees and consultants of Newco with knowledge of relevant
     facts about the Remedial Action and the right to attend all meetings and
     participate in any telephone or other conferences with any government
     agency or third party regarding the Remedial Action.

          (v) In the case of the indemnification contemplated by clauses (iii),
     (iv) and (v) of Section 13.02(b), in the event that either the Indemnified
     Party or the Indemnifying Party desires to settle the matters referenced
     therein or consent to the entry of any judgment arising thereunder and the
     other party does not wish to consent to such settlement, the other party
     shall have no obligation to consent to the settlement provided that it
     agrees in writing to pay and be responsible for 100% of any Damages
     thereafter incurred; provided that no Indemnified Party shall be required
     to consent to any settlement or agree to be responsible for the payment of
     Damages thereafter incurred with respect to any matter the settlement of
     which would require the consent of such Indemnified Party pursuant to
     Section 13.03(b)(iii). The obligation of the party that rejects any
     proposed settlement offer or entry of any such judgment to pay and be
     responsible for 100% of any Damages thereafter incurred in accordance with
     this Section 13.03(b)(v) shall be conditioned upon and subject to the
     payment, within five Business Days of the date such party provides the
     written agreement contemplated by the preceding sentence, of an amount, in
     immediately available funds, equal to the portion of the total settlement
     that would have been payable by the party desiring to settle the matter or
     consent to the entry of any such judgment according to the percentage
     sharing arrangement contemplated by Section 13.04(b)(ii) or Section
     13.04(b)(iii), as the case may be. Thereafter, the party that rejects the
     proposed settlement shall be solely responsible for the defense of the
     matter that is the subject of the proposed settlement.

     (c) If the Indemnifying Party and the Indemnified Party are unable to
agree with respect to a procedural matter arising under Section 13.03(b)(iv),
the Indemnifying Party and the Indemnified Party shall, within 10 days after
notice of disagreement given by either party, agree upon a third-party referee
("Referee"), who shall be an attorney and who shall have the authority to
review and resolve the disputed matter. The parties shall present their
differences in writing (each party simultaneously providing to the other a copy
of all documents submitted) to the Referee and shall cause the Referee promptly
to review any facts, law or arguments either the Indemnifying Party or the
Indemnified Party may present. The Referee shall be retained to resolve
specific differences between the parties within the range of such differences.
Either party may request that all oral arguments presented to the Referee by
either party be in each other's presence. The decision of the Referee shall be
final and binding unless both the Indemnifying Party and the Indemnified Party
agree. The parties shall share equally all costs and fees of the Referee.

     Section  13.04  Limitations.  Notwithstanding anything to the contrary in
this Agreement or in any of the Transaction Documents:

     (a) Newco shall only have liability to Lockheed Martin and its Affiliates
with respect to the representations and warranties described in clause (i) of
Section 13.02(a) if such matters were the subject of a written notice given by
the Indemnified Party pursuant to Section 13.03(a) within the

                                       35

period following the Closing Date specified for each respective matter in
Section 13.01.

     (b) Lockheed Martin shall only have liability to Newco or any other Person
hereunder:

          (i) with respect to the representations and warranties described in

     Damages of all Indemnified Parties as the result thereof exceed $5,000,000

     representations and warranties and this Section 13.04(b)(i) shall be
     $50,000,000), and (z) if such matters were the subject of a written notice

     incurred by all Indemnified Parties after the eighth anniversary of the
     Closing Date and within 15 years following the Closing Date; provided,
     however, that Lockheed Martin shall only have liability under Section
     13.02(b)(iii) or this Section 13.04(b)(ii) for Damages and Operation and
     Maintenance Costs incurred after the Closing Date in excess of $6,000,000;

     (d) Lockheed Martin shall not be liable to Newco or any other Person

     (e) Lockheed Martin shall not be liable to Newco or any other Person under
this Article XIII for any Damages that result from any breach of any
representation or warranty made by Lockheed Martin hereunder to the extent such

knowledge of the Individual Purchasers or a substantially similar clause
relating to their knowledge if either of the Individual Purchasers had such
knowledge as of the Closing.


                                  ARTICLE XIV

                                  TERMINATION

     Section 14.01  Termination.  The Transaction Documents  may be terminated
at any time prior to the Closing:

          (i)  by  mutual  written  agreement  of   Lockheed  Martin  and  the
     Purchasers;

         (ii) by Lockheed Martin or the Purchasers (as a group) if the Closing
     shall not have been consummated by May 30, 1997; provided, however, that
     neither Lockheed Martin nor a Purchaser may terminate the Transaction
     Documents pursuant to this clause (ii) if the Closing shall not have been
     consummated by May 30, 1997, by reason of the failure of such party or any
     of its Affiliates to perform in all material respects any of its or their
     respective covenants or agreements contained in the Transaction Documents;
     provided further, that either Lockheed Martin or Newco and the Purchasers
     (as a group) shall be entitled to terminate the Transaction Documents
     prior to May 30, 1997, if such party or parties, as the case may be, shall
     reasonably conclude that any condition to such party's or parties'
     obligations hereunder (as set forth in Section 12.01 with respect to
     Lockheed Martin, Newco and the Purchasers, Section 12.02 with respect to
     Newco and the Purchasers, and Section 12.03 with respect to Lockheed
     Martin) cannot reasonably be expected to be satisfied prior to May 30,
     1997; and provided, further, that as a condition to the right of a party
     to elect to terminate the Transaction Documents pursuant to the
     immediately preceding proviso, the party shall first provide ten Business
     Days prior notice to the other party specifying in reasonable detail the
     nature of the condition that such party has concluded will not be
     satisfied, and the other party shall be entitled during such ten Business
     Day period to take any actions it may elect consistent with the terms of
     this Agreement such that the condition reasonably could be expected to be
     satisfied prior to the expiration of such time period;

        (iii) by either Lockheed Martin or Newco and the Purchasers (as a
     group) if there shall be any law or regulation that makes consummation of
     the Contemplated Transactions illegal or otherwise prohibited or if
     consummation of the Contemplated Transactions would violate any
     nonappealable final order, decree or judgment of any court or Governmental
     Authority having competent jurisdiction; and

         (iv)  in accordance with the provisions of Section 15.13.

Any party desiring to terminate this Agreement pursuant to this Section 14.01
shall give written notice of such termination to the other parties to this
Agreement.

                                       37

<PAGE>

     Section 14.02 Effect of Termination. If this Agreement is terminated as
permitted by Section 14.01, such termination shall be without liability of any
party (or any Affiliate, shareholder, director, officer, employee, agent,
consultant or representative of such party) to any other party to this
Agreement; provided, however, that if the Contemplated Transactions fail to
close as a result of a breach of any Transaction Document by Lockheed Martin,
Newco or any of the Purchasers, such party shall be fully liable for any and
all Damages incurred or suffered by any other party as a result of all such
breaches in an amount not to exceed $2,500,000, except that Lockheed Martin (i)
shall be fully liable for any and all Damages incurred or suffered by the
Purchasers as a result of any breach by Lockheed Martin of its obligations
under Section 7.03, (ii) shall be fully liable for any and all Damages incurred
or suffered by the Purchasers as a result of Lockheed Martin's willful failure
to consummate the Closing (other than resulting from an unintentional failure
of any of the conditions set forth in Section 12.01 or Section 12.03) if Newco
and the Purchasers have sufficient funds available, and are ready and willing,
to pay the cash portion of the Exchange Consideration for the Transferred
Assets, and (iii) shall not be liable to the Purchasers or any other Person
hereunder for any Damages that result from a breach of the provisions of
Section 7.01 if such breach results from a breach by either of the Individual
Purchasers of Section 8.02(b). The provisions of Sections 8.01 and 15.03 and
this Section 14.02 shall survive any termination hereof pursuant to Section
14.01.

     Section 15.02  Amendments; Waivers.

     (a) Any provision of the Transaction Documents may be amended or waived
prior to the Closing Date if, and only if, such amendment or waiver is in
writing and signed, in the case of an amendment, by Lockheed Martin, Newco and
the Purchasers, or in the case of a waiver, by the party against whom the
waiver is to be effective.

     (b) No failure or delay by any party in exercising any right, power or
privilege under any Transaction Document shall operate as a waiver thereof nor
shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law.

     Section 15.03 Expenses. Except as otherwise provided in the Transaction
Documents and except that if the Closing shall occur the costs and expenses of
the Purchasers will be paid by Newco, all costs and expenses incurred in
connection with the Transaction Documents shall be paid by the party incurring
such cost or expense. Notwithstanding the foregoing, all transfer, sales, use
and similar fees and taxes resulting from or relating to the formation and
organization of Newco, including but not limited to the transfer of the
Transferred Assets to Newco by Lockheed Martin or any of the Affiliated
Transferors, shall be borne one-half by Lockheed Martin and one-half by Newco.
Each of Newco and Lockheed Martin shall reimburse the other

                                       40

<PAGE>

for one-half of such fees and taxes paid by the other promptly upon
presentation of a demand therefor.

     Section 15.04 Successors and Assigns. The provisions of the Transaction
Documents shall be binding upon and inure to the benefit of the parties and
their respective successors and assigns; provided that no party may assign,
delegate or otherwise transfer any of its right or obligations under this
Agreement without the consent of Lockheed Martin, in the case of Newco or any
of the Purchasers, and Newco and the Purchasers in the case of Lockheed Martin.
Notwithstanding the foregoing proviso (i) Lehman may assign all or part of its
rights to Lehman Brothers Holdings Inc. and (ii) Newco may assign all or part
of its rights and obligations (other than the obligation to issue shares of its
capital stock) to a wholly owned Subsidiary of Newco, provided that Newco also
shall remain liable hereunder as if it had not assigned its rights and
obligations.

     Section 15.05 Disclosure. Certain information set forth in the Disclosure
Schedules has been included and disclosed solely for informational purposes and
may not be required to be disclosed pursuant to the terms and conditions of the
Transaction Documents. The disclosure of any such information shall not be
deemed to constitute an acknowledgement or agreement that the information is
required to be disclosed in connection with the representations and warranties
made in the Transaction Documents or that the information is material, nor
shall any information so included and disclosed be deemed to establish a
standard of materiality or otherwise used to determine whether any other
information is material.

     Section 15.06 Construction. As used in the Transaction Documents, any
reference to the masculine, feminine or neuter gender shall include all
genders, the plural shall include the singular, and the singular shall include
the plural. With regard to each and every term and condition of the Transaction
Documents, the parties understand and agree that the same have or has been
mutually negotiated, prepared and drafted, and that if at any time the parties
desire or are required to interpret or construe any such term or condition or
any agreement or instrument subject hereto, no consideration shall be given to
the issue of which party actually prepared, drafted or requested any term or
condition of the Transaction Documents.

     Section 15.07  Entire Agreement.

          (a) The Transaction Documents and any other agreements contemplated
thereby (including, to the extent contemplated herein, the Lehman
Confidentiality Agreement and paragraph 7 of the Memorandum) and certain other
letter agreements entered into contemporaneously herewith constitute the entire
agreement among the parties with respect to the subject matter of such
documents and supersede all prior agreements, understandings and negotiations,
both written and oral, between the parties with respect to the subject matter
thereof.

          (b) The parties hereto acknowledge and agree that no representation,
warranty, promise, inducement, understanding, covenant or agreement has been
made or relied upon by any party hereto other than those expressly set forth in
the Transaction Documents. Without limiting the generality of the disclaimer
set forth in the preceding sentence, neither Lockheed Martin nor any of its
Affiliates has made or shall be deemed to have made any representations or
warranties, in any presentation or written information relating to the Business
given or to be given in connection with

                                       41

<PAGE>

the Contemplated Transactions, in any filing made or to be made by or on behalf
of Lockheed Martin or any of its Affiliates with any governmental agency, and
no statement, made in any such presentation or written materials, made in any
such filing or contained in any such other information shall be deemed a
representation or warranty hereunder or otherwise. The Purchasers acknowledge
that Lockheed Martin has informed them that no Person has been authorized by
Lockheed Martin or any of its Affiliates to make any representation or warranty
in respect of the Business or in connection with the Contemplated Transactions,
unless in writing and contained in this Agreement or in any of the Transaction
Documents to which they are a party.

          (c) Except as expressly provided herein or in any other Transaction
Document, no Transaction Document or any provision thereof is intended to
confer upon any Person other than the parties hereto any rights or remedies
hereunder.

     Section 15.08 Governing Law. Except as otherwise provided in any of the
Transaction Documents, this Agreement shall be construed in accordance with and
governed by the law of the State of New York.

     Section 15.09 Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have
received a counterpart hereof signed by the other parties hereto.

     Section 15.10 Jurisdiction. Any suit, action or proceeding seeking to
enforce any provision of, or based on any matter arising out of or in
connection with, any of the Transaction Documents or the Contemplated
Transactions may be brought against any of the parties in the United States
District Court for the Southern District of New York, and each of the parties
hereby consents to the exclusive jurisdiction of such court (and of the
appropriate appellate court) in any such suit, action or proceeding and waives
any objection to venue laid therein. Process in any such suit, action or
proceeding may be served on any party anywhere in the world, whether within or
without the State of New York. Without limiting the foregoing, Lockheed Martin,
Newco and the Purchasers agree that service of process upon such party at the
address referred to in Section 15.01, together with written notice of such
service to such party, shall be deemed effective service of process upon such
party.

     Section 15.11 Captions. The captions herein are included for convenience
of reference only and shall be ignored in the construction or interpretation
hereof.

     Section 15.12 Bulk Sales. Newco hereby waives compliance by Lockheed
Martin and each Affiliated Transferor, in connection with the Contemplated
Transactions, with the provisions of Article 6 of the Uniform Commercial Code
as adopted in the States of Georgia, Florida, California, Pennsylvania, New
York, Massachusetts, Utah and New Jersey, and as adopted in any other states
where any of the Transferred Assets are located, and any other applicable bulk
sales laws with respect to or requiring notice to Lockheed Martin's (or any
Affiliated Transferor's) creditors, as the same may be in effect on the Closing
Date. Lockheed Martin shall indemnify and hold harmless Newco against any and
all liabilities (other than liabilities in respect of Assumed

                                       42

<PAGE>

Liabilities) which may be asserted by third parties against Newco as a result
of noncompliance with any such bulk sales law.

     Section 15.13  Delivery of Disclosure Schedules; Certain Attachments.

          (a) The parties acknowledge and agree that the Disclosure Schedules
contemplated by this Agreement are not being delivered at the time of signing
of this Agreement. Not later than the close of business on April 14, 1997,
Lockheed Martin shall deliver to Newco the Disclosure Schedules contemplated by
this Agreement, which Disclosure Schedules, once delivered, shall be effective
and speak as of the date of this Agreement as if delivered on the date of this
Agreement. In the event Newco or the Purchasers object to the Disclosure
Schedules, Newco or the Purchasers may, by written notice delivered to Lockheed
Martin prior to the close of business on the fifth Business Day following the
day on which the Disclosure Schedules are delivered to Newco, terminate this
Agreement. In the event Lockheed Martin does not receive such written notice
within the time period specified in the preceding sentence, Newco and the
Purchasers shall be deemed to have accepted the Disclosure Schedules. In the
event that Newco or any of the Purchasers elects to terminate this Agreement in
accordance with the provisions of this Section 15.13(a), no party to this
Agreement shall have any liability to any of the other parties to this
Agreement.

          (b) The parties acknowledge and agree that Attachment X contemplated
by this Agreement is not being delivered at the time of signing of this
Agreement. Not later than the close of business on the third Business Day after
delivery of the Disclosure Schedules, Newco shall deliver to Lockheed Martin a
draft of the portions of Attachment X contemplated by Section 12.01 and Section
12.02. Not later than the close of business on the third Business Day after
delivery of the Disclosure Schedules, Lockheed Martin shall deliver to Newco a
draft of the portion of Attachment X contemplated by Section 12.01. In the
event either Newco or Lockheed Martin objects to any of the matters proposed to
be included by the other party in Attachment X, Newco and Lockheed Martin shall
in good faith discuss the matters to be included in Attachment X. In the event
Newco and Lockheed Martin are unable to reach agreement on the matters to be
included in Attachment X prior to the close of business on the sixth Business
Day after the delivery of the Disclosure Schedules, Attachment X shall include
all matters proposed to be included by each of Newco and Lockheed Martin.

          (c) The parties acknowledge and agree that Attachments IV, V, VIII,
IX, XI and XV as attached to this Agreement at the time of signing of this
Agreement are subject to modification by any of the Purchasers or Lockheed
Martin at any time not later than the close of business on April 4, 1997. In
the event that any of the Purchasers or Lockheed Martin desires to amend either
Attachment IV, Attachment V, Attachment VIII, Attachment IX, Attachment XI or
Attachment XV, it shall notify the other parties in writing of the proposed
amendment and the Purchasers and Lockheed Martin shall, in good faith, discuss
the proposed amendment. In the event that, notwithstanding those discussions,
the Purchasers and Lockheed Martin are unable to resolve the differences as to
the provisions of either Attachment IV, Attachment V, Attachment VIII,
Attachment IX, Attachment XI or Attachment XV, any of the parties may terminate
this Agreement prior to the close of business on April 11, 1997 by written
notice to the other parties to this Agreement and upon any such termination no
party to this Agreement shall have any liability to any other parties to this
Agreement. If this Agreement shall not have been terminated in accordance with
the provisions of this

                                       43

<PAGE>

Section 15.13(c) by the close of business on April 11, 1997, the amended
versions of Attachments IV, V, VIII, IX, XI and XV shall replace Attachments
IV, V, VIII, IX, XI and XV as attached to this Agreement at the time of signing
of this Agreement.

               REPRESENTATIONS AND WARRANTIES OF LOCKHEED MARTIN


     Lockheed Martin hereby represents and warrants prior to but not after the
Closing to the Purchasers, and as of and after the Closing to Newco, that:

     B.01. Corporate Existence and Power. Each of Lockheed Martin and each
Affiliated Transferor is a corporation duly incorporated, validly existing and
in good standing under the laws of the state of its incorporation and has all
corporate powers and all governmental licenses, authorizations, consents and
approvals required to carry on the Business as now conducted, except where the
failure to have such licenses, authorizations, consents and approvals has not
had, and could not reasonably be expected to have, a Material Adverse Effect on
the Business. Each of Lockheed Martin and each Affiliated Transferor, as the
case may be, is duly qualified to do business as a foreign corporation in each
jurisdiction where the character of the property owned or leased by it or the
nature of its activities make such qualification necessary to carry on the
Business as now conducted, except where the failure to be so qualified has not
had, and could not reasonably be expected to have, a Material Adverse Effect on
the Business.

     B.02. Corporate Authorization. The execution, delivery and performance by
each of Lockheed Martin and each Affiliated Transferor of each of the
Transaction Documents to which it is a party and the consummation by Lockheed
Martin and each Affiliated Transferor of the Contemplated Transactions are
within its corporate powers and have been duly authorized by all necessary
corporate action on its part. Each of the Transaction Documents to which it is
a party constitutes a legal, valid and binding agreement of Lockheed Martin and
each Affiliated Transferor enforceable against it in accordance with its terms
(i) except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter
in effect relating to or affecting creditors' rights generally, including the
effect of statutory and other laws regarding fraudulent conveyances and
preferential transfers and (ii) subject to the limitations imposed by general
equitable principles (regardless of whether such enforceability is considered
in a proceeding at law or in equity).

     B.03.     Governmental Authorization.

          (a) The execution, delivery and performance by Lockheed Martin and
each Affiliated Transferor of the Transaction Documents to which it is a party
require no action by or in respect of, or consent or approval of, or filing
with, any Governmental Authority other than:

               (i)  compliance  with any  applicable  requirements of  the HSR
     Act;

              (ii)   compliance with  any applicable  requirements of  the New
     Jersey Industrial Site Recovery Act;

                                       62

<PAGE>

             (iii) the facilities clearance requirements of the Defense
     Investigative Service of the United States Department of Defense ("DIS"),
     as set forth in the DIS Industrial Security Regulation and the DIS
     Industrial Security Manual, as each may be amended from time to time;

              (iv)  the  novation of the  Government Contracts as contemplated
     by Section 7.08 herein;

               (v) any actions, consents, approvals or filings set forth in
     Section B.03 of the Disclosure Schedules or otherwise expressly referred
     to in this Agreement; and

              (vi) such other consents, approvals, authorizations, permits and
     filings the failure to obtain or make would not have, in the aggregate, a
     Material Adverse Effect on the Business.

          (b) To the knowledge of Lockheed Martin, there are no facts relating
to the identity or circumstances of Lockheed Martin or any of its Affiliates
that would prevent or materially delay obtaining any of the consents referred
to in Section B.03(a).

     B.04. Non-Contravention. Except as set forth in Section B.04 of the

              (ii) To the knowledge of Lockheed Martin, except to the extent
     known by the Individual Purchasers with respect to the Business Units
     other than the Communications Systems Business Unit, no fiduciary of any
     funded Employee Plan has engaged in a "prohibited transaction" (as that
     term is defined in Section 4975 of the Code and Section 406 of ERISA)

     Code;

             (iii) No Employee Plan that is subject to Section 412 of the Code

     Martin and the Individual Purchasers have been paid when due;

              (vi) No defined benefit Employee Plan has been terminated; nor

     Section 4043 of ERISA and the regulations thereunder), other than
     reportable events arising directly from the Contemplated Transactions,
     which would present a risk that an Employee Plan would be terminated by
     the PBGC in a distress termination;

             (vii) Each Employee Plan intended to qualify under Section 401 of
     the Code has received a determination letter that it is so qualified and

              (ix) To the knowledge of Lockheed Martin, except to the extent
     known by the Individual Purchasers with respect to the Business Units
     other than the Communications Systems Business Unit, no Employee Plan or
     Benefit Arrangement exists which could result in the payment to any
     Transferred Employee or Transferred Beneficiary of any money or other
     property or rights or accelerate or provide any other rights or benefits
     to any Transferred Employee or Transferred Beneficiary as a result of the
     transaction contemplated by this Agreement, whether or not such payment
     would constitute a parachute payment (within the meaning of Section 280G
     of the Code).

formed, validly existing and in good standing under the laws of the State of
Delaware and has all partnership powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted, except where the failure to have such licenses, authorizations,
consents and approvals has not had and may not reasonably be expected to have,

a foreign limited partnership in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities make such
qualification necessary to carry on its business as now conducted, except for
those jurisdictions where failure to be so qualified has not had, and may not
reasonably be expected to have, a Material Adverse Effect on Lehman.

     C.02. Authorizations. The execution, delivery and performance by Lehman of
the Transaction Documents and the consummation by Lehman of the Contemplated
Transactions are within the partnership powers of Lehman and have been duly
authorized by all necessary partnership action on the part of Lehman. Each of
the Transaction Documents constitutes a legal, valid and binding agreement of
Lehman, enforceable against Lehman in accordance with its terms (i) except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to or affecting creditors' rights generally, including the effect of
statutory and other laws regarding fraudulent conveyances and preferential
transfers and (ii) subject to the limitations imposed by general equitable
principles (regardless of whether such enforceability is considered in a
proceeding at law or in equity).

     C.03.     Governmental Authorization.

          (a) The execution, delivery and performance by Lehman of the
Transaction Documents require no action by or in respect of, consents or
approvals of, or filing with, any governmental body, agency, official or
authority other than:

               (i) compliance with any applicable requirements of the HSR
     Act; and

              (ii) compliance with any applicable requirements of the 1933
     Act.

the identity or circumstances of Lehman or any of its Affiliates that would
prevent or materially delay obtaining the consents or approvals referred to in
Section C.03(a).

     C.04.     Non-Contravention.  The execution, delivery and  performance by
Lehman of  the Transaction Documents  do not  and will not  (i) contravene  or

                                       74

conflict with the certificate of limited partnership or Amended and Restated
Agreement of Limited Partnership of Lehman, (ii) assuming compliance with the
matter referred to in Section C.03, contravene or conflict with or constitute a
violation of any provision of any law, regulation, judgment, injunction, order
or decree binding upon or applicable to Lehman, or (iii) constitute a default
under or give rise to any right of termination, cancellation or acceleration of
any right or obligation of Lehman or to a loss of any benefit to which Lehman
is entitled under any provision of any agreement, contract or other instrument
binding upon Lehman or any license, franchise, permit or other similar
authorization held by Lehman, except, in the case of clauses (ii) and (iii),
for any such contravention, conflict, violation, default, termination,
cancellation, acceleration or loss that would not have a Material Adverse
Effect on Lehman.

     C.05. Finders' Fees. Except for Lehman Brothers Inc., there is no
investment banker, broker, finder or other intermediary that has been retained
by or is authorized to act on behalf of Lehman who might be entitled to any fee
or commission from Newco, Lockheed Martin or any of its Affiliates, or either
of the Individual Purchasers, upon consummation of the Contemplated
Transactions by the Transaction Documents.

     C.06. Litigation. There is no action, suit, investigation or proceeding
pending against, or to the actual knowledge of Lehman, threatened against or
affecting, Lehman before any court or arbitrator or any governmental body,
agency or official which in any matter challenges or seeks to prevent, enjoin,
alter or materially delay the Contemplated Transactions.

     C.07. Inspections. Lehman is an informed and sophisticated participant in
the Contemplated Transactions, and has engaged expert advisors, experienced in
the evaluation and purchase of enterprises such as the Business. Lehman has
undertaken an investigation and has been provided with, has evaluated and has
relied upon certain documents and information to assist Lehman in making an
informed and intelligent decision with respect to the execution of the
Transaction Documents. Lehman will undertake prior to Closing such further
investigation and request such additional documents and information as it deems
necessary. Lehman acknowledges that Lockheed Martin has made no representation
or warranty as to the prospects, financial or otherwise of the Business. Lehman
agrees that Newco shall accept the Transferred Assets and the Assumed
Liabilities as they exist on the Closing Date based upon Lehman's and the
Individual Purchasers' inspection, examination and determination with respect
thereto as to all matters, and without reliance upon any express or implied
representations or warranties of any nature, whether in writing, orally or
otherwise, made by or on behalf of or imputed to Lockheed Martin except as
expressly set forth in the Transaction Documents.

     C.08. Financing. Lehman has available to it cash, marketable securities or
other investments, or presently available sources of credit, to enable it to
purchase the shares of Newco Class A Stock contemplated by this Agreement.

Lockheed Martin shall prepare a schedule (the "Exchange Consideration
Schedule") setting forth the allocation of the cash amount of the Exchange
Consideration among Lockheed Martin and each of the Affiliated Transferors. The
allocation shall be determined based on such appraisal by Coopers & Lybrand
L.L.P., and shall take into account the allocation of Newco Class A Stock among
Lockheed Martin and the Affiliated Transferors, as determined by Lockheed
Martin in its sole discretion. In connection with the preparation of the
Exchange Consideration Schedule, Lockheed Martin shall give Newco reasonable
access to the books and records of Lockheed Martin in respect of the
Transferred Assets and the Basis Liabilities. Lockheed Martin agrees to make
reasonable efforts to allocate the Exchange Consideration in the Exchange
Consideration Schedule in a manner calculated to allow Newco to obtain a tax
basis in the Transferred Assets equal to, but not greater than, $525,000,000
plus or minus any adjustment to the Exchange Consideration in accordance with
Sections 2.03 and 2.04 and plus the Basis Liabilities. Lockheed Martin
covenants and agrees that the Exchange Consideration will be allocated so that
the adjusted tax basis of Newco in the Transferred Assets, based on the
allocation in the Exchange Consideration Schedule, will be not less than
$500,000,000 plus or minus any adjustment to the Exchange Consideration in
accordance with Sections 2.03 and 2.04 and plus the Basis Liabilities.

          (b) The Allocation Tax Loss shall be determined jointly by Lockheed

(b) (regarding determination of the Final Net Tangible Asset Amount). Within 10
days after the Allocation Tax Loss is determined, Lockheed Martin shall pay to
Newco the amount of the Allocation Tax Loss with interest thereon from the
Closing Date to the date of payment at a rate per annum equal to the per annum
interest rate announced from time to time by Bank of America National Trust and
Savings Association as its reference rate in effect. Such payment shall be made
in immediately available funds by wire transfer to a bank account designated in
writing by Newco. Newco agrees that the aforementioned payment by Lockheed
Martin shall satisfy all obligations assumed by Lockheed Martin pursuant to
this Section F.05. Lockheed Martin shall have no further obligation to
indemnify Newco with regard to any adjustment to the tax basis of the
Transferred Assets in the hands of Newco as a result of an audit by the
Internal Revenue Service or any other Tax authority, or as a result of any
other adjustment which is treated for Tax purposes as an adjustment to the
Exchange Consideration.

     F.06. Representations and Warranties of Lockheed Martin. Lockheed Martin
hereby represents prior to but not after the Closing to the Purchasers, and as
of and after the Closing to Newco that:

          (a)  there are no liens on any of the Transferred Assets  that arose
in connection with any failure (or alleged failure) to pay any Tax;

                                       82

<PAGE>

          (b) neither Lockheed Martin nor any of the Affiliated Transferors
will take part in both a Section 351 Transfer and a Cash Sale in the context of
the Contemplated Transactions;

          (c) neither Lockheed Martin nor any of the Affiliated Transferors has
transferred or otherwise altered the ownership of any of the Transferred Assets
in anticipation of the Contemplated Transactions.

     F.07. Consistent Reporting.

          (a)  Section 351 Transfers

               (i) Unless there has been a Final Determination to the contrary,
     Lockheed Martin, the Affiliated Transferors and Newco covenant and agree,
     for all Tax purposes including all Tax returns and Tax controversies, to
     (and to cause any Affiliate or successor to their assets or business to)
     take each of the positions set forth in subparagraph (A) through (E) below
     with respect to Section 351 Transfers.

                    (A) The transfer of assets by each transferor will qualify
     under Section 351(b) of the Internal Revenue Code of 1986.

                    (B) The amount of cash received in exchange for any
     Transferred Asset will be determined by (A) allocating Basis Liabilities
     to the Transferred Assets in proportion to the adjusted tax basis of such
     Transferred Assets, and then (B) allocating the total amount of cash
     received by the transferor among the Transferred Assets in proportion to
     the net fair market value of such Transferred Assets (the net fair market
     value being the fair market value of a Transferred Asset reduced by the
     amount of any Basis Liabilities allocated to the asset).

                    (C) The tax basis of each Transferred Asset to be received
     by Newco will be the same as the tax basis of such asset in the hands of
     the transferor increased by the amount of any gain recognized by the
     transferor on the transfer of such asset.

                    (D) The fair market value of each category of Transferred
     Assets will be determined based on an independent appraisal by Coopers &
     Lybrand L.L.P.

                    (E) Neither Newco, nor any successor to its assets or
     businesses will be entitled to claim any deduction in respect of any Basis
     Liability to the extent previously deducted by the transferor, unless such
     previous deduction is later denied.

              (ii) Lockheed Martin and the Affiliated Transferors will file
     with their consolidated federal income tax return for the tax period which
     includes the Tax Closing Date the information required by Treas. Reg.
     1.351-3(a) and will deliver copies of such statements, including
     attachments, to Newco at least 10 days prior to the date on which such
     return is filed, and Newco will file with its federal income tax return
     for the taxable period within which the Tax Closing Date falls the
     information required by Treas. Reg. 1.351-(b) and will deliver a copy of
     that statement to Lockheed Martin within ten days thereafter. Within 180
     days after the Closing Date, Lockheed Martin will deliver to Newco all of
     the cost and other basis information relating to the Transferred

                                       83

<PAGE>

     Assets  and Basis  Liabilities reasonably required  for Newco  to prepare
     the Statement required by Treas. Reg. 1.351-3(b)(2).

             (iii) Lockheed Martin and Newco will jointly prepare schedules
     showing (A) the amount of any gain recognized on the transfer of each
     category of Transferred Assets, (B) the tax basis of each category of
     Transferred Assets in the hands of the transferor, and (C) the amount
     previously deducted in respect of each category of Basis Liabilities. Such
     schedules will be prepared in a manner consistent with each of the
     positions described in Section F.07.(a)(i). In the event of any adjustment
     to the tax basis of the Transferred Assets or Basis Liabilities, as the
     result of an audit or otherwise, Lockheed Martin, the Affiliated
     Transferors and Newco will jointly prepare any necessary revisions to such
     schedules. Unless there has been a Final Determination to the contrary,
     Lockheed Martin, the Affiliated Transferors and Newco covenant and agree,
     for all Income Tax purposes, including all Income Tax returns and any
     Income Tax controversies, not to take (and to cause any Affiliate or
     successors to their assets or businesses not to take) any position
     inconsistent with the basis in assets shown on such schedules (including
     any revised schedules from and after the date of revision) prepared
     pursuant to this Section F.07.(a)(iii).

              (iv) Lockheed Martin and the Affiliated Transferors covenant and
     agree to make the election necessary under Section 197(f)(9)(B) of the
     Code and pay the Tax that is required to be paid thereunder, so that
     intangible assets will be amortizable to the extent allowable under
     Section 197 of the Code. Lockheed Martin will deliver a copy of the
     election to Newco within 10 days of filing or making such election.

          (b)  Cash Sales

               With respect to Cash Sales, the Exchange Consideration shall be
allocated among the Transferred Assets in accordance with Section 1060 of the
Code and Treasury Regulations thereunder. Such allocation shall be based on an
independent appraisal by Coopers & Lybrand L.L.P. Lockheed Martin, the
Affiliated Transferors and Newco shall not take any position on their
respective Tax returns that is inconsistent with such allocation of the
Exchange Consideration for purposes of determining the amount of gain or loss
recognized by Lockheed Martin and/or any of the Affiliated Transferors pursuant
to Cash Sales, and Lockheed Martin and Newco shall duly prepare and timely file
such reports and information returns as may be required to report the
allocation, including Internal Revenue Service Form 8594. Lockheed Martin and
Newco will each deliver a copy of Form 8594, including attachments, to the
other at least 10 days prior to filing it with its tax return.

     F.08. Allocation of Income, Deductions and Other Items. For purposes of
the Transaction Agreement, income, deductions, and other items will be
allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period
based on an actual closing of the books of the Business on the Tax Closing
Date. Income, deductions and other items attributable to the Pre-Closing Tax
Period will be included in the federal and state income and/or franchise tax
returns of Lockheed Martin. Income, deductions and other items attributable to
the Post-Closing Tax Period will be included in the federal and state income
and/or franchise tax returns of Newco.

                                       84

<PAGE>

     F.09. Allocation of Taxes. Any pre-paid asset or accrued liability for
real property tax, personal property tax or any similar ad valorem obligation
levied with respect to any Transferred Asset for a Post-Closing Tax Period
which includes the Tax Closing Date will be apportioned as of the Tax Closing
Date and included in the determination of the Estimated Final Net Tangible
Asset Amount, the Proposed Final Net Tangible Asset Amount and the Final Net
Tangible Asset Amount based on the number of days of such taxable period
included in the Pre-Closing Tax Period and the number of days of such taxable
period included in the Post-Closing Tax Period.

     F.10. Credit for Increasing Research Activities. Lockheed Martin, the
Affiliated Transferors and Newco agree that the transfers of assets pursuant to
the Transaction Agreement constitute dispositions of trades or businesses
within the meaning of Section 41(f)(3) of the Code. Lockheed Martin and the
Affiliated Transferors agree to provide Newco within 150 days after the Closing
Date with all information necessary to permit Newco to timely apply the
provisions of Section 41(f)(3)(A) of the Code with respect to the Businesses.

     F.11. Costs and Expenses of Appraisal. The costs and expenses of the
appraisal by Coopers & Lybrand L.L.P. which is referred to in Sections F.05.,
F.07.(a)(i)(D) and F.07.(b) shall be shared equally by Lockheed Martin and
Newco.

     F.12. Resale Certificates. Within 45 days after the Closing Date, where
applicable, Newco shall remit to Lockheed Martin such properly completed resale
exemption certificates or similar certificates or instruments as are necessary
to claim exemptions from the payment of sales, transfer, use or other similar
taxes under Applicable Law.

                    EMPLOYMENT AND EMPLOYEE BENEFIT MATTERS


     G.01. Employee Benefits Definitions. The following terms shall have the
following meanings:

     "Benefit Arrangement" means each employment, severance, continuation pay,
termination pay, layoff, or other similar written contract, arrangement or
policy and each written plan or arrangement providing for health, medical, life
or other welfare or fringe benefit coverage (including any insurance,
self-insurance or other arrangements), workers' compensation, severance pay,
retention agreements, disability benefits, supplemental unemployment benefits,
holiday, education or vacation benefits, retirement benefits or deferred
compensation, profit-sharing, benefits in the event of a sale of the Business
or other change in the control, management or the ownership of the Business,

compensation or post-retirement insurance, compensation or benefits which (i)
is not an Employee Plan, (ii) is or has been entered into, maintained,
administered or contributed to, as the case may be, by Lockheed Martin or any
of its Affiliates and (iii) covers any Transferred Employee, Transferred
Beneficiary and/or his or her dependent, spouse or beneficiary or for which a
Transferred Employee would be eligible upon retirement or other termination of
service.

     "Camden Transferee" means each Transferred Employee who worked in the
Communications Systems Business Unit immediately prior to Closing and any
Transferred Beneficiary related to such Transferred Employee.

     "Employee Plan" means each "employee benefit plan", as such term is
defined in Section 3(3) of ERISA, which (i) is subject to any provision of
ERISA, (ii) is or has been entered into, maintained, administered or
contributed to by Lockheed Martin or any of its Affiliates and (iii) covers any
Transferred Employee and/or Transferred Beneficiary.

     "ERISA" means the  Employee Retirement  Income Security Act  of 1974,  as
amended.

     "Transferred Employee" means any Person who, (i) on the Closing Date, is
actively employed in the Business, or who, with respect to the Business, is on
vacation, approved illness absence, long-term disability, authorized leave of
absence (including leave under the Family and Medical Leave Act) or military
service leave of absence as of the Closing Date, (ii) was laid off from the
Business and has recall rights with respect to the Business, or (iii) is
identified on Attachment XI, to be delivered to Newco at the same time as the
Disclosure Schedules are delivered.

     "Transferred Beneficiary" means any Person who, at Closing, is not a
Transferred Employee but (i) who was formerly employed in the Business (other
than at the Communications Systems Business Unit)(whether by Lockheed Martin
and/or its Affiliates or by their predecessors with respect to the Business)
and to whom or with respect to whom Lockheed Martin or any of its Affiliates
now has or may have in the future any obligation or liability (whether or not
contingent) arising from that Person's employment in the Business or who is now
or may become entitled to any coverage or benefit (whether or not

                                       86

<PAGE>

contingent) provided under any Employee Plan or Benefit Arrangement as a result
of his or her employment in the Business; (ii) who is the spouse, dependent or
beneficiary of a Person who qualifies as a Transferred Employee or a Person
described in clause (i), if that spouse, dependent or beneficiary is or may
become entitled to any coverage or benefit (whether or not contingent) provided
under any Employee Plan or Benefit Arrangement as a result of that Person's
employment in the Business.

     G.02. Employees and Offers of Employment.

          (a) Newco shall offer employment to commence on the Closing Date to
all Transferred Employees; provided that, for any Transferred Employee who is
on vacation, approved illness absence, authorized leave of absence (including
leave under the Family and Medical Leave Act), long-term disability or military
service leave of absence as of the Closing, the offer shall remain open until
the date he or she is able to return to active employment to the extent
consistent with any applicable collective bargaining agreement and/or existing
company policy; provided, further, that any Camden Transferee entitled to
recall rights shall be offered employment by Newco in accordance with the terms
of the applicable bargaining agreement. Each Transferred Employee shall be
offered a position by Newco similar to his or her position immediately prior to
the Closing Date, at the same job and salary or wage levels, with non-equity
based bonus and incentive plans and other non-equity based employee benefit
plans substantially similar to those provided by Lockheed Martin and its
Affiliates immediately prior to the Closing Date. Such offers of employment
shall be at the same respective locations as those at which such Transferred
Employees are employed immediately prior to the Closing. Subject to Applicable
Law and this Agreement, Newco shall have the right to dismiss any Transferred
Employee at any time, with or without cause, and to change the terms of
employment of any Transferred Employee.

          (b) Lockheed Martin shall provide any notices to Transferred
Employees which may be required under the Worker Adjustment Retraining and
Notification Act, 29 USC Section 2101 et seq., ("WARN") with respect to events
which occur prior to the Closing Date and Newco shall provide any notices to
Transferred Employees which may be required under WARN with respect to events
which occur on or after the Closing Date.

          (c) Commencing on the Closing Date, Newco shall assume all
responsibility and liability for all matters arising out of or relating to
Transferred Employees and Transferred Beneficiaries regardless of whether such
matter arises from or relates to events prior to, on or after the Closing Date,
including but not limited to (i) accrued but unpaid wages, bonuses and salary;
(ii) all liabilities for workers compensation claims made at any time by
Transferred Employees or Transferred Beneficiaries whether or not reported as
of the Closing Date and all expenses of administration of such claims; (iii)
all incurred but not reported claims for life insurance, medical, disability or
similar benefits; (iv) all claims relating to the terms and conditions of
employment, hiring, firing, supervision, occupational safety and health,
workplace, wages and hours promotion, employment practices or treatment of
Transferred Employees or Transferred Beneficiaries; provided, however, that
with respect to any responsibility and liability relating to a Camden
Transferee for a matter described in clause (iv), Newco shall only assume such
responsibility and liability if it arises from or relates to (A) a matter
described in Section B.09 of the Disclosure Schedule, or (B) events occurring
on or after the Closing Date.

                                       87

<PAGE>

     G.03. Plans Following the Closing.

          (a) Except to the extent changes are (i) required by Applicable Law;
(ii) necessary to maintain the tax favored status of any employee plan or
benefit arrangement; (iii) permitted or required under any applicable
collective bargaining agreement; or (iv) necessary to eliminate the use of any
equity securities as the basis for any equity-based incentive compensation,
during the one-year period following the Closing, Newco will maintain employee
compensation and employee plans and benefit arrangements for the benefit of the
Transferred Employees and Transferred Beneficiaries, in either case, who are
not covered by collective bargaining agreements, that are substantially similar
to the Employee Plans and Benefit Arrangements (excluding any stock options,
stock appreciation or other equity based incentive compensation) in effect on
the Closing Date; provided, however, that layoff, severance and retention
benefits (including the Special Severance Program) shall be identical during
this period; provided, further, that post-retirement benefits for Camden
Transferees shall also be provided in accordance with Sections G.03(b) and
G.05(f). During such period, for Transferred Employees and Transferred
Beneficiaries who are covered by collective bargaining agreements, Newco shall
provide such benefits as are required by any and such collective bargaining
agreements as are assumed pursuant to Section G.04. Newco will give Transferred
Employees full credit for purposes of eligibility, vesting and benefit accrual
under any such plans or arrangements maintained by Newco pursuant to this
Section G.03 for such Transferred Employees' service recognized for such
purposes under the Employee Plans and Benefit Arrangements at Closing;
provided, however, that any Newco pension plan may offset pension benefits
provided under Newco's pension plan to a Transferred Employee and attributable
to service before the Closing Date by any pension benefits provided to that
Transferred Employee under any Lockheed Martin pension plan and attributable to
that same pre-Closing service.

          (b) Effective as of the Closing Date, Lockheed Martin and its
Affiliates shall cease to have any liability or obligation to provide
post-retirement medical and life insurance benefits to Transferred Employees
and Transferred Beneficiaries and Newco shall assume all such liabilities and
obligations to provide post-retirement life and medical benefits and shall
provide post-retirement medical and life insurance benefits in accordance with
Section G.03(a). In addition, Newco will provide (i) substantially equivalent
post-retirement medical benefits for Camden Transferees who meet the age and
service requirements for those benefits (as such requirements are in effect
under the applicable Lockheed Martin plan immediately prior to the Closing
Date) by the five-year anniversary of the Closing Date and who retire before
that 5th year anniversary; (ii) substantially equivalent post retirement life
insurance benefits for those Camden Transferees who were at least age 50 as of
December 31, 1994 and have ten years of continuous service at retirement; and
(iii) post-retirement medical benefits and life insurance for Transferred
Employees and Transferred Beneficiaries covered by a collective bargaining
agreement in accordance with the terms of that agreement. Notwithstanding the
foregoing, nothing herein shall prevent Newco from increasing the cost to
Transferred Employees or Transferred Beneficiaries who became participants in
such plans to the extent permitted by law, but only if the proportion of any
required payments by such participants does not change in relation to the
payments made prior to the Closing Date by such participant's employer;
provided, however, nothing herein permits the level of benefits provided under
the plans to be decreased.

                                       88

<PAGE>

          (c) Newco's plans that are welfare plans (as defined in Section 3(1)
of ERISA) shall not contain a clause excluding coverage for preexisting
conditions of Transferred Employees or Transferred Beneficiaries (unless and
only to the extent and for the period that such pre-existing condition as of
the Closing Date would be excluded from coverage under the welfare plans of the
Business) and shall provide that any expenses incurred by a Transferred
Employee or Transferred Beneficiary during 1997 on or before the Closing shall
be taken into account from the Closing until December 31, 1997 under such
welfare plans for the purposes of deductible and coinsurance requirements and
satisfaction of maximum out-of-pocket provisions to the same extent as if such
expenses had been incurred after the Closing.

          (d) Effective as of the Closing Date, Newco and Lockheed Martin shall
enter into a benefit administration agreement or agreements, whereby Newco
shall provide to Lockheed Martin and Lockheed Martin shall provide to Newco,
upon reasonable request, assistance in the administration of benefit plans and
arrangements after the Closing Date. Newco and Lockheed Martin agree to
negotiate in good faith the cost of such services and actual terms of such
benefit administration agreement(s).

     G.04. Collective Bargaining Agreements. Newco shall (i) expressly
recognize any collective bargaining representative recognized by Lockheed
Martin or any of its Affiliates as of the Closing for bargaining units
consisting of Transferred Employees; (ii) expressly assume any and all of
Lockheed Martin's and its Affiliates' obligations under the collective
bargaining agreements set forth on Section B.21 of the Disclosure Schedules
with respect to the Transferred Employees; and (iii) be a successor employer
for purposes of such collective bargaining agreements.

     G.05. Pension Plan Obligations

          (a) Transferred Employees currently participate in the following
defined benefit pension plans: (i) Lockheed Martin Tactical Defense Systems
Retirement Plan; (ii) Lockheed Martin Corporation Retirement Income Plan II;
(iii) Lockheed Martin Corporation Pension Plan for Employees in Participating
Bargaining Units; (iv) The Narda Microwave Corporation Pension Plan; (v)
Lockheed Martin Tactical Systems, Inc. Pension Plan; (vi) Lockheed Martin
Fairchild Corporation Retirement Plan; (vii) Lockheed Martin Hycor Pension
Plan; (viii) Lockheed Martin Retirement Income Plan; (ix) Lockheed Martin
Supplemental Retirement Income Plan; (x) Lockheed Martin Retirement Plan for
Certain Salaried Employees; (xi) Lockheed Martin Tactical Systems, Inc.
Supplemental Executive Retirement Plan; (xii) Lockheed Martin Corporation
Supplementary Pension Plan for Employees of Transferred GE Operations; (xiii)
Supplemental Executive Retirement Plan for Certain Management Employees of the
Narda Microwave Corporation; (xiv) Lockheed Martin Fairchild Corporation
Supplemental Benefit Plan; (xv) Lockheed Martin Supplemental Executive
Retirement Plan ("Lockheed Martin Pension Plans"). As of the Closing Date,
Transferred Employees shall cease to accrue service credit or benefits under
Lockheed Martin Pension Plans, other than the Assumed Plans described in
Section G.05(b).

          (b) With respect to The Narda Microwave Corporation Pension Plan
("Narda Plan") and the Lockheed Martin Hycor Pension Plan ("Hycor Plan")
(collectively, the "Assumed Plans"), as of the Closing Date, Lockheed Martin
and its Affiliates shall cease to sponsor, administer, pay benefits or
contribute to the Assumed Plans (other than for contributions due prior to the
Effective Date) and thereby cease to be responsible for any acts,

                                       89

<PAGE>

omissions and transactions under or in connection with any such Assumed Plan,
whether occurring before or after Closing. Effective as of the Closing Date,
Newco shall become the sponsor of the Assumed Plans. Contingent upon receipt of
the Initial Transfer Amount in the case of the Narda Plan or the transfer of
sponsorship of the trust in the case of the Hycor Plan, Newco shall assume all
liabilities with respect to such Assumed Plan (including liabilities with
respect to Transferred Beneficiaries), shall assume responsibility for paying
pension benefits in respect of Transferred Employees and Transferred
Beneficiaries, and shall become responsible for all acts, omissions and
transactions under or in connection with that Assumed Plan, whether arising
before or after the Closing. As soon as practicable after the Closing Date, the
parties shall cause the sponsorship of the trust agreement maintained to fund
the Hycor Plan to be transferred to Newco and Newco, as of the Closing Date,
shall assume all of Lockheed Martin's and its Affiliates rights, obligations
and duties under that trust agreement. Lockheed Martin shall cause the trusts
holding the assets of the Narda Plan to transfer the assets attributable to the
Narda Plan (determined as of the end of the month in which the Closing Date
occurs) to be transferred to a trust (or trusts) designated by Newco for the
purpose of holding the assets of the Narda Plan.

          (c) With respect to the (i) Lockheed Martin Tactical Defense Systems
Retirement Plan; (ii) Lockheed Martin Corporation Retirement Income Plan II;
(iii) Lockheed Martin Corporation Pension Plan for Employees in Participating
Bargaining Units; (iv) Lockheed Martin Tactical Systems, Inc. Pension Plan; (v)
Lockheed Martin Fairchild Corporation Retirement Plan; and (vi) Lockheed Martin
Retirement Income Plan (the "Spinoff Plans"), Newco shall establish a defined
benefit plan or plans which provide substantially similar benefits in
accordance with Section G.03(a), where applicable,(the "Newco Spinoff Plans")
for the benefit of the Transferred Employees and Transferred Beneficiaries
participating in the Spinoff Plans. As soon as practicable following the
Closing, Lockheed Martin shall cause its actuary to calculate the Accrued
Liability of all participants in each of the Spinoff Plans and then to compare,
on a plan by plan basis, the Accrued Liability of all the participants in each
of the Spinoff Plans to the fair market value of the assets in the respective
Spinoff Plan as of the end of the month in which the Closing Date occurs. If
the Accrued Liability of all participants in the respective Spinoff Plan is
less than the fair market value of the assets in that Spinoff Plan, then
Lockheed Martin shall cause assets (determined as of the end of the month in
which the Closing Date occurs) to be transferred to a trust established to hold
assets of the respective Newco Spinoff Plan equal to such fair market value of
the assets multiplied by a fraction the numerator of which is the Accrued
Liability of Transferred Employees and Transferred Beneficiaries under such
Spinoff Plan and the denominator of which is the Accrued Liability of all
participants in such plan. If the Accrued Liability of all participants in the
respective Spinoff Plan is equal to or more than the fair market value of the
assets in that Spinoff Plan, then Lockheed Martin shall cause its actuary to
determine the amount of assets allocable to the liabilities of Transferred
Employees and Transferred Beneficiaries participating in that plan based on
Section 4044 of ERISA ("Section 4044 Amount"). Lockheed Martin shall cause
assets in cash equal to the Section 4044 Amount applicable to Transferred
Employees and Transferred Beneficiaries under such Spinoff Plan to be
transferred to a trust established by Newco to hold assets of the respective
Newco Spinoff Plans. Contingent upon the transfer of the Initial Transfer
Amount (as described in Section G.05(b)) to each Newco Spinoff Plan, Newco
shall assume all liabilities of Lockheed Martin and its affiliates with respect
to Transferred Employees and Transferred Beneficiaries under the Spinoff Plan
from which

                                       90

<PAGE>

that transfer was made and shall become with respect to such Transferred
Employees and Transferred Beneficiaries responsible for all acts, omissions and
transactions under or in connection with such Spinoff Plan, whether arising
before or after the Closing; provided, however, that in the case of liabilities
with respect to Camden Transferees, Newco shall only assume liabilities and
shall only become responsible for all acts, omissions and transactions under or
in connection with that Spinoff Plan arising on or after the Closing or
disclosed in Section B.21 of the Disclosure Schedules.

          (d) All transfers to the Narda Plan and the Newco Spinoff Plans shall
be made in accordance with the provisions of this Section G.05(d). Within 30
days of the Closing Date, or if later, 20 days following the date on which
Lockheed Martin has been provided evidence reasonably satisfactory to it that
Newco has established a trust (or trusts) to hold the assets of the Narda Plan
and the Newco Spinoff Plans and that the Newco Spinoff Plans are qualified
under Section 401(a) of the Code and the trusts holding assets of the Newco
Spinoff Plans or Narda Plan are tax exempt under Section 501(a) of the Code
("Initial Transfer Date"), Lockheed Martin shall cause its trusts to make an
initial transfer of assets in cash equal to 85% of the amount estimated by
Lockheed Martin in good faith to be equal to X (as defined below) with respect
to each plan (using the same assumptions and methodologies consistent with
estimates previously provided to Newco and as set forth in a schedule to be
presented at Closing by Lockheed Martin) ("Initial Transfer Amount"). In
addition, prior to the Initial Transfer Date Lockheed Martin shall provide
Newco with evidence reasonably satisfactory to Newco that the appropriate
Lockheed Martin Pension Plans remain qualified under Section 401(a) of the
Code. As soon as practicable after the final determination of the amounts to be
transferred ("True-Up Date"), Lockheed Martin shall cause a second transfer to
be made in cash of the "True-Up Amount." The True-Up Amount shall be equal to
the sum of the following amount with respect to the Narda Plan and each Spinoff
Plan:

     (X minus Initial Transfer Amount), minus benefit payments, adjusted for
     Earnings,

where X equals in the case of the Spinoff Plans, the Accrued Liability or the
Section 4044 Amount, whichever is applicable, and in the case of the Narda
Plan, the fair market value of the assets attributable to the Narda Plan at the
end of the month in which the Closing Date occurs. Earnings shall be calculated
(i) from the last day of the month following the Closing until the Initial
Transfer Date on the amount equal to the Initial Transfer Amount using the rate
paid on a 90-day Treasury Bill on the auction date coincident with or
immediately preceding the Closing, (ii) from the Initial Transfer Date until
the True-Up Date on an amount equal to X minus the sum of the Initial Transfer
Amount and the benefit payments using (A) with respect to the period from the
Closing Date to the last day of the month preceding the True-Up Date, the
cumulative rate of return (considering both gain and loss) earned or lost on
the assets of the trust from which the True-Up Amount is being transferred and
(B) with respect to the period from the first day of the month in which the
True-Up Date occurs and the True-Up Date the rate paid on a 90-Day Treasury
Bill on the auction date coincident with or immediately preceding the first day
of the month in which the True-Up Date occurs. If the Initial Transfer Amount
exceeds X with respect to any plan, as soon as practicable following such
determination Newco shall cause a transfer to be made to the respective
Lockheed Martin Pension Plan equal to the difference between the Initial
Transfer Amount and X, adjusted to reflect Earnings (i) from the last day of
the month in which the Closing occurs until the Initial

                                       91

<PAGE>

Transfer Date using the rate paid on a 90-day Treasury Bill on the auction date
coincident with or immediately preceding the Closing; (ii) from the Initial
Transfer Date until the date of transfer, such Earnings shall be calculated
using (A) with respect to the period from that Initial Transfer Date to the
last day of the month preceding such transfer, the cumulative rate of return
(considering both gain and loss) on the assets of the plan from which the
transfer is being transferred and (B) with respect to the period from the first
day of the month in which the transfer occurs and the date of such transfer,
the rate paid on a 90-Day Treasury Bill on the auction date coincident with or
immediately preceding the first day of the month in which the transfer occurs.
The True-Up Amount shall be transferred in cash except benefits of Transferred
Employees and Transferred Beneficiaries attributable to John Hancock Group
Annuity Contract 8474 shall be transferred in kind. Unless the parties agree
otherwise, all transfers will occur on the last business day of a month.
Notwithstanding anything contained herein to the contrary, the transfers
contemplated by this section G.05(d) shall be determined in accordance with
Section 414(l) of the Code and Treasury Regulation 1.414(l)-1. The amounts to
be transferred pursuant to this section G.05(d) shall be reduced to the extent
necessary to satisfy Section 414(l) of the Code, and any regulations
promulgated thereunder, ERISA Section 4044, and any regulations promulgated
thereunder.

          (e) For the purposes of this Section, the term "Accrued Liability"
shall mean the present value of the accrued benefit of the Transferred Employee
or Transferred Beneficiary, determined on a termination basis using the
interest factors specified by the PBGC for an immediate or deferred annuity as
appropriate for such Transferred Employee or Transferred Beneficiary and the
other methods and factors specified in the regulations of the PBGC for the
valuation of accrued benefits upon plan termination, including, but not limited
to, expected retirement ages and expense load assumptions published by the
PBGC, and the 1983 Group Annuity Mortality Table. The interest factors shall be
those in effect on the Closing Date. The Accrued Liability and Section 4044
Amount shall be determined by an enrolled actuary designated by Lockheed
Martin. Lockheed Martin shall provide any actuary designated by Newco with all
information reasonably necessary to review the calculation of the Accrued
Liability and the Section 4044 Amount in all material respects and to verify
that such calculations have been performed in a manner consistent with the
terms of this Agreement. If there is a good faith dispute between Lockheed
Martin's actuary and Newco's actuary as to the amount to be transferred to any
plan, and such dispute remains unresolved for 30 days, the chief financial
officers of the respective companies shall endeavor to resolve the issue.
Should such dispute remain unresolved for 60 days, Lockheed Martin and Newco
shall select and appoint a third actuary who is mutually satisfactory to both
of the parties hereto. The decision of such third party actuary shall be
rendered within 30 days and shall be conclusive as to any dispute for which it
was appointed. The cost of such third party actuary shall be divided equally
between Lockheed Martin and Newco. Each party shall be responsible for the cost
of its own actuary.

          (f) Newco shall take all action necessary to qualify each Newco
Spinoff Plan under the applicable provisions of the Code and Newco and Lockheed
Martin shall cooperate to make any and all filings and submissions to the
appropriate governmental agencies required to be made by Newco as are
appropriate in effectuating the provisions hereof. The Newco Spinoff Plans and
Assumed Plans and any successor plans thereto shall contain appropriate
provisions providing that through the first year anniversary of the Closing

                                       92

<PAGE>

(fifth anniversary in the case of Lockheed Martin Retirement Income Plan II and
Lockheed Martin Retirement Income Plan), each Newco Spinoff Plan shall provide
for a benefit formula that is no less favorable than the formula provided in
the corresponding Spinoff Plan at Closing. The Newco Spinoff Plans or Assumed
Plans receiving a transfer from the Lockheed Martin Corporation Retirement
Income Plan II and the Lockheed Martin Corporation Pension Plan for Employees
in Participating Bargaining Units and any successor plans thereto shall contain
appropriate provisions providing that (i) to the extent assets transferred are
attributable to assets transferred from the GE Pension Plan or are governed by
collective bargaining agreements, any such assets shall be held by trusts
forming a part of such Newco Spinoff Plans (or successor plans) and shall be
held for the exclusive benefit of the participants in such Newco Spinoff Plans
(or successor plans) and such assets shall not upon termination of those Newco
Spinoff Plans (or successor plans) revert to the employer or sponsor of such
Newco Spinoff Plans (or successor plans); (ii) the accrued benefits as of the
Closing of Transferred Employees under such plans may not be decreased by
amendment or otherwise; and (iii) each Transferred Employee retiring under
Newco Spinoff Plans (or successor plans) will be entitled to receive pension
benefits no less than what would have been received under the GE Pension Plan
as in effect as of April 5, 1993, taking into account the Transferred
Employee's combined service with Newco, Lockheed Martin, GE, and RCA and each
of their Affiliates.

          (g) With respect to the (i) Lockheed Martin Tactical Systems, Inc.
Supplemental Executive Retirement Plan ("LMTS SERP"); (ii) the Lockheed Martin
Corporation Supplementary Pension Plan for Employees of Transferred GE
Operations ("Supplementary Plan"), the Lockheed Martin Supplemental Executive
Retirement Plan, the Lockheed Martin Supplemental Retirement Income Plan (the
"Camden SERPs"); and (iii) the Supplemental Executive Retirement Plan for
Certain Management Employees of Narda Microwave Corporation, and Lockheed
Martin Fairchild Corporation Supplemental Benefit Plan, (the plans in (i),
(ii), and (iii) collectively referred to as the "LMC SERPs"), Newco shall
establish a nonqualified plan or plans (the "Newco SERP") for the benefit of
Transferred Employees and Transferred Beneficiaries participating in the LMC
SERPs as of the Closing Date and Newco shall assume all obligations and
liabilities under the LMC SERPs, with respect to the Transferred Employees and
the Transferred Beneficiaries. Effective as of the Closing Date, all
Transferred Employees will cease to accrue benefits under the LMC SERPs. With
respect to the Supplementary Plan, Newco will provide an equivalent plan for
Transferred Employees and Transferred Beneficiaries eligible to participate in
that plan as of the Closing Date that provides equivalent benefits during the
entire term of their employment with Newco, its Affiliates and their
successors. With respect to the LMC SERPs (other than the Supplementary Plan),
Newco shall provide a substantially similar plan in accordance with the
provisions of Section G.03(a). As soon as practicable (but not more than 180
days) after the Closing Date, Lockheed Martin shall cause its actuary to
calculate the SERP Liability of all participants in the LMTS SERP and the
Camden SERPS, respectively, and the SERP Liability for Transferred Employees
and Transferred Beneficiaries in the LMTS and Camden SERPS respectively and
shall cause the following transfers. As soon as practicable thereafter, but in
no event later than the later of (i) the acceptance of the calculation of the
SERP Liability by Newco or (ii) 20 days following submission to Lockheed Martin
of evidence reasonably satisfactory to it that Newco has established a
corresponding rabbi trust or trusts, Lockheed Martin shall cause a transfer of
assets from the rabbi trust established in connection with the LMTS SERP ("LMTS
Trust") to a rabbi trust established by Newco in an amount equal to the product
of the (i) fair market

                                       93

<PAGE>

value of the assets of the LMTS Trust as of the last day of the month in which
the Closing Date occurs; and (ii) a fraction, the numerator of which is the
"SERP Liability" for Transferred Employees and Transferred Beneficiaries
participating in the LMTS SERP and the denominator of which is the SERP
Liability for all participants in the LMTS SERP. Lockheed Martin shall also
cause a transfer of assets from the rabbi trust established in connection with
the Camden SERPs ("Camden Trust") to a rabbi trust established by Newco in an
amount equal to the product of the (i) fair market value of the assets of the
Camden Trust as of the last day of the month in which the Closing Date occurs;
and (ii) a fraction, the numerator of which is the "SERP Liability" for
Transferred Employees and Transferred Beneficiaries participating in the Camden
SERPs and the denominator of which is the SERP Liability for all participants
in the Camden SERPs. The amount of the transfer shall be reduced by benefits
paid by Lockheed Martin prior to the transfer. If the amount of the benefits
paid exceeds the amount of the transfer, Newco shall promptly pay Lockheed
Martin such excess. For the purpose of this section, the "SERP Liability" with
respect to a participant shall be the lump sum present value (determined as of
the end of the month in which the Closing Date occurs) of the accrued benefit
of the participant under the applicable SERP calculated utilizing the
assumptions used by Lockheed Martin for reporting accrued benefit obligations
relative to Seller Pension Plans under FAS No. 87 in its 1996 Annual Report.
The calculation of the amount to be transferred shall be subject to the review
and dispute resolution procedures contained in subsection (e).

          (h) No later than the True-Up Date, Lockheed Martin shall also cause
the Lockheed Martin Federal Systems, Inc. Retirement Plan ("Federal Systems
Plan") to make a transfer to a qualified defined benefit plan designated by
Newco in an amount equal to the accrued benefit of the Transferred Employees
who participated in the Federal Systems Plan immediately prior to the Closing.
For the purposes of this section, the accrued benefit of the Transferred
Employees shall mean the present value of the accrued benefit determined on a
termination basis using the interest factors for an immediate or deferred
annuity as appropriate for each such Transferred Employee. The assumptions used
in determining the accrued benefit of each such Transferred Employee shall be
the same as the assumptions used to determine Accrued Liability under Section
G.05(e). The transfer shall be contingent upon Newco providing evidence
reasonably satisfactory to Lockheed Martin that such designated plan is
qualified under Section 401(a) of the Code and the trust of which it is a part
is exempt from taxation under Section 501(a) of the Code. Lockheed Martin shall
also provide to Newco evidence reasonably satisfactory to Newco that the
Federal Systems Plan is qualified under Section 401(a) of the Code and the
trust of which it is a part is exempt from taxation under Section 501(a) of the
Code. Upon receipt of such transfer of assets, Newco shall assume all
liabilities of Lockheed Martin and its Affiliates with respect to such
Transferred Employees under the Federal Systems Plan and shall become with
respect to such Transferred Employees responsible for all acts, obligations,
omissions and transactions under or in connection with the Federal Systems
Plan, whether arising before or after the Closing. Lockheed Martin shall cause
the benefits accrued as of the Closing Date by any Transferred Employee or
Transferred Beneficiary under the Lockheed Martin Retirement Plan for Certain
Salaried Employees (the "Lockheed Plan") or any other defined benefit pension
plan that is not listed in Schedule G.05(a) or this G.05(h) to be fully vested
at the Closing Date and any such Transferred Employee or Transferred
Beneficiary shall be eligible on the Closing Date to participate in the Newco
defined benefit plans (the "Newco Plans") established for other Transferred

                                       94

<PAGE>

Employees or Transferred Beneficiaries who were formerly employed in the
Communications Systems Business Unit (or such other plan as Newco designates in
the case of Transferred Employees covered under any plan other than the
Lockheed Plan). Newco shall credit such Transferred Employees and Transferred
Beneficiaries with all service recognized under the Lockheed Plan or such other
plans as the case may be. If the Transferred Employee participated in the plan
for more than one year, Lockheed Martin shall credit such Transferred Employees
and Transferred Beneficiaries with all service recognized under the Newco Plans
for all purposes, other than benefit accrual and will recognize Newco
compensation for calculating pensionable earnings under the Lockheed Plan or
any other such plan which is a final average pay plan.

     G.06.  Savings Plan Obligations.

          (a) Transferred Employees currently participate in the following
defined contribution plans: (i) Lockheed Martin Defense Systems Savings and
Investment Plan; (ii) Lockheed Martin Salaried Savings Plan; (iii) Lockheed
Martin Salaried Savings Plan II; (iv) Lockheed Martin Performance Sharing Plan;
(v) Lockheed Martin Supplemental Savings Plan; (vi) Conic Corporation Deferred
Income Retirement Plan; (vii) Narda Microwave Supplemental Retirement Savings
Plan; (viii) Narda Western Operations 401(k) Deferred Income Retirement Plan;
(ix) Lockheed Martin Tactical Systems, Inc. Deferred Income Savings Plan; (x)
Lockheed Martin Fairchild Corporation Savings Plan; (xi) Randtron Employees
Retirement Savings Plan; (xii) Microcom Corporation 401(k) Plan; (xiii) Profit
Sharing Plan and Trust of Lockheed Martin Hycor, Inc., (xiv) Lockheed Martin
Tactical Systems Inc. Frequency Sources, Inc. 401(k) Retirement Plan and (xv)
Lockheed Martin Federal Systems Deferred Income Retirement Plan (collectively,
"Lockheed Martin Defined Contribution Plans"). The plans listed in (i), (vi),
(vii), (viii), (ix), (xiv) and (xv) are all sub-plans in the Lockheed Martin
Tactical Systems Master Savings Plan.

          (b) Effective as of the Closing Date, Lockheed Martin and Newco shall
cause (i) Randtron Employees Retirement Plan; (ii) Microcom Corporation 401K
Plan; (iii) Profit Sharing Plan and Trust of Lockheed Martin Hycor, Inc.
("Transferred Savings Plans") to be amended to provide that sponsorship and
maintenance thereof shall be transferred to Newco and Newco shall assume all of
the obligations and liabilities of Lockheed Martin and its Affiliates with
respect to each such Transferred Plan (including liabilities with respect to
Transferred Beneficiaries) and contingent upon receipt of the transferred
assets described in Section G.06(c), shall become responsible for all acts,
omissions and transactions under or in connection with the Transferred Savings
Plan, whether arising before or after Closing. Effective as of the Closing
Date, Lockheed Martin and/or its Affiliates shall cease to sponsor, administer
or contribute (other than contributions in respect of benefits accrued prior to
the Effective Date) to the Transferred Savings Plans and thereby cease to be
responsible for any acts, omissions and transactions under or in connection
with any such Transferred Savings Plan.

          (c) With respect to all Lockheed Martin Defined Contribution Plans
except the Transferred Savings Plans described in Section G.06(b) (the
"Lockheed Martin Savings Plans"), the Transferred Employees shall cease to
accrue benefits and service credits under such plans as of the Closing Date
and, effective as of the Closing Date, Newco shall establish new savings plans
("Newco's Savings Plans") and associated trusts to hold the assets of those
plans for the Transferred Employees, to be effective as of the Closing

                                       95

<PAGE>

Date, and shall provide to Lockheed Martin evidence reasonably satisfactory to
Lockheed Martin that Newco's Savings Plans and the associated trusts have been
established and that the Newco's Savings Plans qualify under the requirements
of Section 401(a) of the Code, and that the trusts are exempt from tax under
Section 501(a) of the Code. Lockheed Martin shall provide to Newco evidence
reasonably satisfactory to Newco that the Lockheed Martin Savings Plans remain
qualified under the requirements of Section 401(a) of the Code. Provided
Lockheed Martin and Newco have received evidence reasonably satisfactory to
them in accordance with the preceding sentences, as soon as is reasonably
practicable following the Closing Date, in no event later than 60 days
following receipt of such mutually satisfactory evidence, Lockheed Martin shall
take or cause to be taken all action required or appropriate to transfer the
account balances of all Transferred Employees and Transferred Beneficiaries to
the respective trusts associated with Newco's Savings Plans. Such transfers
shall be made in cash in an amount equal to the value of the account balances
to be transferred, determined as of the close of business on the last business
day immediately preceding the transfer, except that (i) to the extent a
participant's or beneficiary's account balance in the transferor plan includes
one or more promissory notes evidencing a participant loan or loans, such
promissory notes shall be transferred in kind for the participant's or
beneficiary's credit under the transferee plan and (ii) any assets in the
transferor trust consisting of securities issued by Lockheed Martin, Martin
Marietta Materials, Inc. or Loral Space & Communications, Ltd. that are
allocable to the respective transferee plan shall be transferred in kind. For
the period from the Closing Date until the transfer, Newco shall collect by
payroll deduction and promptly pay over to the respective Lockheed Martin
Defined Contribution Plan all loan payments required on participant loans made
by the respective plan to any Transferred Employee and Lockheed Martin shall
cause the respective Lockheed Martin Defined Contribution Plan to administer
and pay all distributions, withdrawals and loans payable under the terms of the
respective plan to any Transferred Employee or Transferred Beneficiary until
the transfer. Contingent upon the transfer of the account balances to each of
Newco's Savings Plans, Newco shall assume all liabilities of Lockheed Martin
and its affiliates with respect to Transferred Employees and Transferred
Beneficiaries under the Lockheed Martin Defined Contribution Plan from which
that transfer was made and shall become with respect to such Transferred
Employees and Transferred Beneficiaries responsible for all acts, omissions and
transactions under or in connection with such Lockheed Martin Defined
Contribution Plan, whether arising before or after the Closing; provided,
however, that in the case of liabilities with respect to Camden Transferees,
Newco shall only assume liabilities and shall only become responsible for all
acts, omissions and transactions under or in connection with that Lockheed
Martin Defined Contribution Plan arising after the Closing or disclosed in
Section B.21 of the Disclosure Schedules.

     G.07. GE Special Benefits Protections. Pursuant to Section V.II of Exhibit
V to a Transaction Agreement (the "GE Agreement") dated November 22, 1992, as
amended, among GE, Martin Marietta Corporation, a Maryland corporation and
Lockheed Martin, Lockheed Martin has agreed to reimburse GE (the "GE
Reimbursement Obligations") for certain specified expenses relating to benefits
for certain individuals who were formerly employed by GE and who became
employees of Lockheed Martin or its Affiliates as a result of the transaction
contemplated by the GE Agreement (the "Former GE Employees"). Newco shall
assume, effective on the Closing Date, all of the GE Reimbursement Obligations
in respect of Transferred Employees and Transferred Beneficiaries for such
specified expenses, and shall indemnify and hold

                                       96

<PAGE>

harmless Lockheed Martin and its Affiliates from any and all such GE
Reimbursement Obligations. Lockheed Martin shall provide Newco with copies of
any documentation it receives from GE documenting the basis for such expenses.

     G.08. Severance and Retention Agreements. In accordance with Section 6.9
of the Agreement and Plan of Merger dated as of January 7, 1996, by and among
Loral Corporation, Lockheed Martin Corporation and LAC Acquisition Corporation,
Lockheed Martin Tactical Systems, Inc. has adopted the Supplemental Severance
Program. Lockheed Martin has entered into Key Employee Supplemental Severance
Program and Key Executive Supplemental Severance Program agreements (the
"Program Agreements"). In addition, Lockheed Martin has entered into Retention
Agreements (collectively with the Supplemental Severance Program and the
Program Agreements, the "Supplemental Agreements") with certain Transferred
Employees who participate in the Supplemental Severance Program. Other than
with respect to the Transferred Employees set forth on Section B.21 of the
Disclosure Schedules, Newco assumes all obligations and liabilities of Lockheed
Martin and its Affiliates under the Supplemental Agreements for all claims made
after the Closing Date by Transferred Employees, including claims based on the
Contemplated Transactions, which shall be Assumed Liabilities for purposes of
this Agreement. All obligations and liabilities of Lockheed Martin with respect
to the Transferred Employees on Section B.21 of the Disclosure Schedules and
any other individual covered by a Supplemental Agreement who is not a
Transferred Employee shall constitute Excluded Liabilities.

     G.09. Vacation and Holidays. As of the Closing, Newco shall adopt at its
expense, vacation and holiday plans for Transferred Employees to succeed
Lockheed Martin's and its Affiliates' vacation and holiday plans. For the
12-month period beginning with the Closing Date, such plans shall provide for
accrued vacation and holidays no less favorable than, and in substitution for,
those Lockheed Martin and its Affiliates would have provided to such
Transferred Employees had they remained employees of Lockheed Martin and its
Affiliates, and Lockheed Martin and its Affiliates shall have no liability or
obligation to pay or provide any vacation or holiday payments claimed on or
after the Closing Date. Thereafter, such plans shall provide vacation, accrued
vacation and holidays to each eligible Transferred Employee on the basis of his
or her continuous service with Lockheed Martin, Newco and their Affiliates.

     G.10. Other Employee Plans.

          (a) Newco shall, as of the Closing Date, assume all obligations and
liabilities of Lockheed Martin and its Affiliates in respect of Transferred
Employees and Transferred Beneficiaries under the Deferred
Management Incentive Compensation Plan.

          (b) Newco shall, as of the Closing Date, assume all obligations and
liabilities (including, without limitation, all obligations and liabilities
attributable to the period prior to the Closing Date) of Lockheed Martin and
its Affiliates in respect of Transferred Employees and Transferred
Beneficiaries under each Employee Plan and Benefit Arrangement not covered
under Sections G.05, G.06, G.07, G.08, G.09, G.10(a) and G.10(c) and shall be a
successor employer with respect to such plans; provided, however, that with
respect to obligations and liabilities to Camden Transferees arising from
events occurring prior to the Closing Date, Newco shall assume such obligations
and liabilities only to the extent that they (i) arise under a

                                       97

<PAGE>

Benefit Arrangement or Employee Plan disclosed in Section B.21 of the
Disclosure Schedules; (ii) are reflected in the Final Net Tangible Asset
Amount; or (iii) are incurred after the Effective Date.

          (c) With respect to each Employee Plan and Benefit Arrangement (other
than those referred to in Sections G.05, G.06, G.07, G.08, G.09 and G.10(a)),
including any employment agreement, that covers only Transferred Employees
and/or Transferred Beneficiaries ("Transferred Benefit Plans"), Lockheed Martin
and Newco shall cause each Transferred Benefit Plan to be amended to provide
that sponsorship and maintenance thereof shall be transferred as of the Closing
Date to Newco and Newco shall assume all obligations and liabilities of
Lockheed Martin and its Affiliates with respect to each such plan (including
liabilities with respect to Transferred Beneficiaries), and shall become
responsible for all acts, omissions and transactions under or in connection
with the Transferred Benefit Plans, whether arising before or after Closing;
provided, however, that with respect to obligations and liabilities to Camden
Transferees under or otherwise arising in connection with an Employee Plan or
Benefit Arrangement arising from events occurring prior to the Closing Date,
Newco shall assume such obligations and liabilities only to the extent that
they (i) arise under an Employee Plan or Benefit Arrangement disclosed in
Section B.21 of the Disclosure Schedules; (ii) are reflected in the Final Net
Tangible Asset Amount; or (iii) are incurred after the Closing Date. Effective
as of the Closing Date, Lockheed Martin and/or its Affiliates shall cease to
sponsor, administer or contribute to the Transferred Benefit Plans and thereby
cease to be responsible for any acts, omissions and transactions under or in
connection with any such Transferred Benefit Plan, whether occurring before or
after Closing. Except as otherwise agreed to by the parties or as it relates
solely to an Individual Purchaser, Lockheed Martin agrees to transfer any
assets which are separately identifiable or attributable to the Employee Plans
and Benefit Arrangements described in this Section G.10(c).

          (d) As of the Closing Date, Transferred Employees and Transferred
Beneficiaries shall cease to accrue or enjoy benefits under any Employee Plans
and Benefit Arrangements (excluding those referred to in Sections G.05(b),
G.06(b), G.07, G.08, G.09 and G.10(c)) and shall commence accrual of benefits
and participation in those employee compensation and benefit plan and
arrangements maintained by Newco pursuant to Section G.03.

          (e) For any full or partial contract year or plan year prior to the
Closing Date of any Employee Plan or Benefit Arrangement covering Transferred
Employees or Transferred Beneficiaries (other than Camden Transferees): (i)
Lockheed Martin agrees to carve out and transfer to the corresponding Newco
plan, any surpluses, refunds or rebates received by or attributable to Lockheed
Martin for any Employee Plan or Benefit Arrangement and (ii) Newco agrees to
transfer to the corresponding Lockheed Martin Plan an amount equal to any
deficit charged to or attributable to Lockheed Martin for any Employee Plan or
Benefit Arrangement, in either case that is attributable to Transferred
Employees and/or Transferred Beneficiaries.

          (f) The flexible spending accounts established on behalf of the
Transferred Employees and Transferred Beneficiaries in accordance with Section
G.03(a) will be maintained through the end of the applicable plan year in which
the Closing occurs in a manner that ensures that each Transferred Employee and
Transferred Beneficiary receives no more and no less than he or she would have
received had the Contemplated Transactions not occurred. Lockheed Martin and
Newco shall coordinate management of their

                                       98

<PAGE>

respective flexible spending accounts to achieve this result. As soon as
practicable following the close of the 1997 plan year, Lockheed Martin and
Newco shall reconcile flexible spending account balances so as to achieve an
equitable result as between Lockheed Martin and Newco.

     G.11. Necessary Action. Newco and Lockheed Martin agree to take all action
which may be necessary in order to effectuate the transactions contemplated by
this Exhibit G, including, without limitation, adopting any necessary
amendments to the Employee Plans and Benefit Arrangements and making all
filings and submissions to the appropriate governmental agencies required to be
made in connection with the segregation and/or transfer of assets contemplated
by Sections G.05 and G.06.

     G.12. Third Party Beneficiaries. No provision of this Exhibit G shall
create any third party beneficiary rights in any employee or former employee of
the Business (including any beneficiary or dependent thereof) including,
without limitation, any right to continued employment or employment in any
particular position by Newco for any specified period of time after the Closing
Date.

     G.13. Plan Administration. Newco shall prepare and file all Forms 5500 and
other government reports or returns that are required to be filed after the
Closing Date with respect to each of the Assumed Plans described in Section
G.05(b), the Transferred Savings Plans described in Section G.06(b) and the
Transferred Benefit Plans described in Section G.10(c).

     G.14. Mutual Assistance. At all times after the Closing Date, Newco and
Lockheed Martin agree to make reasonably available to each other and each
other's agents, employees, accountants and other representatives such
actuarial, financial, personnel and related information as may be requested
with respect to any Employee Plan or Benefit Arrangement, Transferred Employee
or Transferred Beneficiary, including but not limited to benefit records,
compensation and employment histories, policies, interpretations and other
records relating to the Employee Plans and Benefit Arrangements.

     G.15. Flanigan v. G.E. Newco shall not by reason of the transactions
contemplated by this Agreement or otherwise be deemed to have assumed any
liability or obligation with respect to any claim or cause of action asserted
against GE or Lockheed Martin in the lawsuit Flanigan v. G.E. filed in the
federal district court in Connecticut in March, 1993. All such claims and
causes of action shall constitute Excluded Liabilities for purposes of this
Agreement. Nothing in this Section G.15. or elsewhere, however, shall be deemed
to require Lockheed Martin to indemnify or otherwise to relieve Newco of any
liability or obligation it may incur as a result of a purported claim or
purported cause of action asserted against Newco which is based on this
Agreement, the Contemplated Transactions, or any actions or transactions that
occur on or after the date of this Agreement.

     This Amendment No. 1 to Transaction Agreement (the "Amendment") is made as
of the 11th day of April, 1997, by and among Lockheed Martin Corporation, a
Maryland corporation ("Lockheed Martin"), Lehman Brothers Capital Partners III,
L.P., a Delaware limited partnership ("Lehman"), Frank C. Lanza ("Lanza"),
Robert V. LaPenta ("LaPenta"; and together with Lanza, the "Individual

"Purchasers."

                             W I T N E S S E T H:

     WHEREAS, Lockheed Martin, in its own right and through certain of its

          from the Closing Date until such time as the Transferred Employee or
          Transferred Beneficiary no longer has an account balance in any
          Lockheed Martin Defined Contribution Plan, Newco shall collect by
          payroll deduction and promptly pay over to the respective Lockheed
          Martin Defined Contribution Plan all loan payments required on
          participant loans made by the respective plan to any Transferred
          Employee and Lockheed Martin shall cause the respective Lockheed
          Martin Defined Contribution Plan to

                                       2

<PAGE>

          administer and pay all distributions, withdrawals and loans payable
          under the terms of the respective plan. Contingent upon the transfer
          of an account balance to each of Newco's Savings Plans, Newco shall
          assume all liabilities of Lockheed Martin and its affiliates with
          respect to that Transferred Employee or Transferred Beneficiary under
          the Lockheed Martin Defined Contribution Plan from which that
          transfer was made and shall become with respect to such Transferred
          Employee and Transferred Beneficiary responsible for all acts,
          omissions and transactions under or in connection with such Lockheed
          Martin Defined Contribution Plan, whether arising before or after the
          Closing; provided, however, that in the case of any liabilities with
          respect to Camden Transferees (other than Camden Transferrees for
          whom no such transfer was made), Newco shall only assume liabilities
          and shall only become responsible for all acts, omissions and
          transactions under or in connection with that Lockheed Martin Defined
          Contribution Plan arising after the Closing or disclosed in Section
          B.21 of the Disclosure Schedules."

                              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:

<PAGE>

Any such notice or communication shall be delivered by hand or by courier or
sent certified or registered mail, return receipt requested, postage prepaid,
addressed as above (or to such other address as such party may designate in a
notice duly delivered as described above), and the third business day after the
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

                              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
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:

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.

         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.

                                LEASE AGREEMENT


          This Lease Agreement (the "Agreement") is entered into this 1st day
of November, 1995 between KSL, a division of Bonneville International
Corporation, a Utah corporation, with its principal place of business at
Broadcast House, 55 North 300 West, P. O. Box 1160, Salt Lake City, Utah
84110-1160 ("Lessor") and Loral Communication Systems, a New York corporation,
with its principal place of business at 640 North 2200 West, Salt Lake City,
Utah 84116 ("Lessee"), in light of the following circumstances:

                                   Recitals

          Whereas, Lessor is the owner of certain television and radio
transmission facilities located in the Oquirrh mountain range in Salt Lake and
Tooele counties, Utah at a location commonly known as Farnsworth Peak (the
"Site"); and

          Whereas, Lessee is engaged in the business of satellite
communications and data link services; and

          Whereas, Lessee desires to lease from Lessor certain space and
equipment at the Site;

          Now, therefore, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged, Lessor and Lessee agree as follows:

                             Terms and Conditions

          1. Leased Premises. Lessor hereby leases to Lessee, and Lessee hereby
accepts from Lessor, that certain space and equipment at the Site identified on
Schedule A to this Agreement (the "Premises") for the location and operation of
a test antenna of approximately six feet in length. A complete list of Lessee's
equipment to be located at the Premises (the "Equipment") is attached to this
Agreement as Schedule B.

          2.  During Furnished Items.  During the term of this Agreement,
Lessor shall furnish Lessee with the following:

          A. Access to the Site over the access road available to Lessor for
     that purpose. Lessee understands that it will be subject to the same
     restrictions on the use of such road as may be imposed on Lessor from time
     to time by the entities controlling the property upon which the road is
     located, including the Kennecott Copper Corporation, Alpha
     Communications and Hercules Corporation;

          B. Heat, light and toilet facilities at the Site;

          C. The right to connect to the power load center at the Site for the
     operation of the Equipment. Lessee's use of electricity will be separately
     metered by Lessor. Lessor shall invoice Lessee monthly for such electrical
     usage at the established commercial rates of the Utah Power and Light
     Company, plus the lesser of ten percent of Lessee's monthly statement or
     $30.00 for administration and general expenses.

                                       8

<PAGE>

     Invoices shall be payable within twenty days of the date of billing. In
     the event an invoice is more than ten days delinquent, Lessor, upon five
     days written notice, shall be entitled to cease supplying Lessee with
     electricity;

          D. Upon Lessee's request, emergency service, if available, for the
     Equipment.  Rates for emergency service are set forth in Schedule O to
     this Agreement and may be adjusted from time to time as determined by
     Lessor;

          E. The right to make reasonable alterations, attach fixtures and
     erect additions to the Premises as required to operate the Equipment, but
     only so long as plans for such alterations, attachments or additions are
     submitted, along with a list of added and/or replaced materials, to Lessor
     for approval, which approval shall not be unreasonably withheld. In no
     event shall any of Lessee's alterations, attachments or additions
     interfere with the operation or work of Lessor or of other tenants at the
     Site;

          F. Other services, such as the use of tools and parts owned by
     Lessor, at the rates listed on Schedule O, as such may be adjusted from
     time to time as determined by Lessor; and

          G. Maintenance of the Site in good operating order.

          3. Monthly Payments by Lessee. In exchange for the right to occupy
the Premises and operate the Equipment, Lessee shall pay to Lessor the monthly
rental payment and other fees set forth in Schedule C to this Agreement. The
monthly rental payment shall be payable in advance on or before the first day
of each calendar month at Lessor's principal place of business or at such other
place or in such other manner as Lessor may from time to time direct; provided,
however, that in the event the term of this Agreement shall commence on other
than the first day of a calendar month or terminate on other than the last day
of a calendar month, the monthly rental payment shall be prorated on a daily
basis for such partial calendar month. Unless otherwise specifically set forth
elsewhere in this Agreement, all other payments required to be made by Lessee
to Lessor shall be paid by within twenty days of the date of invoice.

          4. Other Costs. Lessee recognizes that additional expenses may be
incurred by Lessor from time to time for the benefit of Lessee and other
tenants at the Site, such as the cost of transporting various government
inspectors, tax assessors, state and/or county officers/officials and the like
to and from the Site. Lessee agrees to pay its share of such costs on a pro
rata basis as calculated by Lessor. Lessor shall provide Lessee with proof of
such costs, along with calculations for determining the amount charged to
Lessee.

          5. Compliance. Lessee's operations at the Site shall be in full
compliance with all applicable laws, statutes, ordinances, rules and
regulations of any governmental authority having jurisdiction over Lessor,
Lessee or the Site, including, but not limited to, the Federal Communications
Commission (the "FCC"). Lessee shall bear the cost and responsibility for all
matters pertaining to its operations at the Site, including, but not limited
to, applications, renewals, regular or special reports, discrepancy citations,
inspections or any changes in equipment which may be required from time to time
by the FCC or standards of good engineering practice.

                                       9

<PAGE>

          Lessee shall protect all persons at the Site at all times from
exposure to excessive non-ionizing radiation (as determined by the FCC, the
Occupational Safety and Health Agency, the Environmental Protection Agency or
any other governmental authority) which may be generated as a result of
Lessee's operations. In the event Lessee's operations appear to be causing
excessive non-ionizing radiation, Lessor shall have the right, but not the
obligation, to take whatever action Lessor deems appropriate to reduce the
amount of such radiation, including, but not limited to, the interruption of
Lessee's operations or the reduction of Lessee's transmission power. Lessor
shall invoice Lessee for the costs of any such action and Lessee shall promptly
pay such amount within twenty days of the date of invoice.

          6. Interference. Lessee acknowledges that Lessor reserves the right
to grant space, premises, facilities and/or rights to third parties at the Site
that are the same as or similar to those granted herein to Lessee. Lessee shall
endeavor in good faith to conduct its activities in accordance with sound
electronic and engineering practices and applicable FCC standards and will
cooperate with Lessor and other tenants at the Site so as to anticipate and
prevent Interference, as that term is defined below. A list of Tenants at the
Site as of the commencement of this Agreement is attached hereto as Schedule S.

          If Lessee's operations cause Interference, Lessee shall, at its sole
cost and expense and without recourse to Lessor, cause any such Interference to
be corrected within ten days following written notice thereof to Lessee.
Pending correction, Lessee shall immediately cease the activity or remove the
equipment causing the Interference. If Lessee fails to act within the given
time frame, Lessor may cause the required corrections to be made. Lessor shall
invoice Lessee for the costs of any such action and Lessee shall promptly pay
such amount within twenty days of the date of invoice.

          "Interference" shall be deemed to exist if (i) a final determination
to that effect is made by an authorized representative of the FCC pursuant to
its rules and regulations; (ii) a condition exists which constitutes
interference within the meaning of the provisions of the rules and regulations
of the FCC in effect at the time; or (iii) Lessor makes a good faith
determination that its technical operations or the technical operations of any
other tenants at the Site are being adversely affected by Lessee's activities.

          7. Lessor Improvements. Lessor reserves the right to replace or
install additional equipment at the Site necessary or desirable for its own
operations. Lessor shall not be liable for any disruption of or interference to
Lessee's operations by reason of such replacement or installation, but Lessor
agrees to cooperate with Lessee and to use reasonable efforts to resolve in
advance any problems that might arise in connection with these activities.

          8. Assignment or Sublease. Lessee may not assign or transfer this
Agreement or any interest therein, sublease any interest covered by this
Agreement or encumber, hypothecate or otherwise give as security this Agreement
or any interest therein without the prior written consent of Lessor, which
consent shall not be unreasonably withheld. No assignment, transfer or sublease
shall be effective as against Lessor for any purpose, unless Lessor shall have
consented thereto in writing prior to such assignment, transfer or sublease and
unless all sums due from Lessee,

                                       10

<PAGE>

together with any costs to Lessor to cover reasonable legal and other expenses
of Lessor in connection with such assignment, transfer or sublease, shall have
been paid to Lessor.

          Each and every attempt to assign, sell, transfer or encumber this
Agreement or any interest therein and each and every attempt to sublease any
interest covered hereby in a manner contrary to that set forth in this
paragraph may be deemed a default by Lessee hereunder.

          Lessor's consent to one assignment, transfer or sublease by Lessee or
acceptance of performance from an assignee, transferee or sublessee shall not
be deemed a waiver by Lessor of the restrictions of this paragraph as to
subsequent attempts to assign, transfer or sublet by Lessee or by Lessee's
heirs, successors, assigns, transferees or sublessees. As used herein, the
terms Lessor and Lessee shall be deemed to include their respective heirs,
successors, assigns, transferees or sublessees.

          The terms, conditions and covenants contained in this Agreement shall
apply to, inure to the benefit of and be binding upon the parties hereto and
their respective legal representatives, successors, assigns, transferees and
sublessees.

          Lessor shall have the right to transfer and assign, in whole or in
part, all of its rights and obligations hereunder and in the Site and in such
event Lessor shall be released from any further obligations hereunder and the
successor-in-interest of Lessor shall have all the rights and obligations
hereunder and in the Site with respect to Lessee.

          9. Term. The initial term of this Agreement shall begin on November
1, 1995 and shall end on October 31, 1996. This Agreement shall thereafter be
renewed for up to three additional two year periods (from November 1, 1996
through October 31, 1998; from November 1, 1998 through October 31, 2000; and
from November 1, 2000 through October 31, 2002, respectively) upon the same
terms and conditions set forth herein unless Lessee provides Lessor with
written notice at least ninety days prior to the expiration of the then current
term.

          10.  Default by Lessee.  The following events shall be deemed to be
events of default by Lessee under this Agreement (each such event of default
is hereinafter referred to as an "Event of Default"):

          A.  Lessee shall fail to timely pay any monthly rental payment as
     referenced in paragraph 3 above or any other sum of money due hereunder
     and such failure shall continue for a period of ten days;

          B. Lessee shall fail to comply with any provision of this Agreement
     not requiring the payment of money, all of which provisions shall be
     deemed material, and such failure shall continue for a period of twenty
     days after written notice of such default is delivered to Lessee;

          C.  Lessee shall become insolvent or fail to pay its debts as they
     become due or Lessee notifies Lessor that it anticipates either
     condition;

          D.  Lessee takes any action to file a petition under any section or
     chapter of the United States Bankruptcy Code or under any similar law or

                                       11

<PAGE>

     statute of the United States or any state thereof or a petition shall be
     filed against Lessee under any such statute or Lessee or any creditor of
     Lessee notifies Lessor that it knows such a petition will be filed or
     Lessee notifies Lessor that it expects such a petition to be filed; or

          E.  A receiver or trustee shall be appointed for Lessee's leasehold
     interest in the Premises or for all or a substantial part of Lessee's
     assets.

          Upon the occurrence of any Event of Default, Lessor may at its option
and without further notice to all other remedies given hereunder or by law or
in equity, do any one or more of the following: (i) terminate this Agreement,
in which event Lessee shall immediately surrender possession of the Premises to
Lessor; (ii) enter upon the Premises and expel or remove Lessee's Equipment
therefrom, with or without having terminated this Agreement; and (iii) change
or re-key all locks to entrances to the Site and Lessor shall have no
obligation to give Lessee notice thereof or to provide Lessee with a new key to
the Site.

          The exercise by Lessor of any one or more remedies hereunder shall
not constitute an acceptance of the surrender of the Premises by Lessee. Lessee
acknowledges that a surrender of the Premises can be effected only by a written
agreement between Lessor and Lessee.

          If Lessor terminates this Agreement by reason of an Event of Default,
Lessee shall pay to Lessor the sum of (i) the cost of recovering the Premises;
(ii) the unpaid monthly payments and all other indebtedness accrued hereunder
to the date of such termination; (iii) to the extent the same were not paid,
the cost of repairing, altering or otherwise putting the Premises into a
condition acceptable to a new tenant or tenants (if Lessor elects to so relet)
(collectively, the "Reletting Expenses"); (iv) all expenses incurred by Lessor
in enforcing Lessor's remedies, including attorneys' fees and court costs; (v)
the total monthly payments and other benefits which Lessor would have received
under this Agreement for the remainder of the term, minus any net sums
thereafter received by Lessor through reletting the Premises during such
period; and (vi) any other damages or relief which Lessor may be entitled to at
law or in equity. Lessee shall not be entitled to any excess rent obtained by
reletting the Premises.

          If Lessor repossesses the Premises without terminating this Agreement
by reason of an Event of Default, then Lessee shall pay to Lessor the sum of
(i) the cost of recovering the Premises; (ii) the unpaid monthly payments and
all other indebtedness accrued hereunder to the date of such repossession;
(iii) the Reletting Expenses; (iv) all expenses incurred by Lessor in enforcing
Lessor's remedies, including attorneys' fees and court costs; (v) the total
monthly payments and other benefits which Lessor would have received under this
Agreement for the remainder of the term, minus any net sums thereafter received
by Lessor through reletting the Premises during such period; and (vi) any other
damages or relief which Lessor may be entitled to at law or in equity. Re-entry
by Lessor will not affect the obligations of Lessee for the unexpired term of
this Agreement. Lessee shall not be entitled to any excess rent obtained by
reletting the Premises. Actions to collect amounts due by Lessee may be brought
on one or more occasions without the necessity of Lessor's waiting until the
expiration of the term of this Agreement.

                                       12

<PAGE>

          Upon termination of this Agreement or repossession of the Premises
due to an Event of Default, Lessor shall not be obligated to relet or attempt
to relet the Premises or any portion thereof or to collect rent after
reletting, but Lessor shall have the option to relet the whole or any portion
of the Premises for any period to any tenant and for any use and purpose.

          11. Insurance. Lessee shall at its own cost and expense procure and
maintain general liability insurance coverage and automobile coverage in the

any federal, state or local authority; or (iii) arises from the activities of
Lessee in and around the Site or the operations or conduct of Lessee's business
upon the Site (collectively, the "Claims"), except to the extent such Claims
are directly caused by the gross negligence or willful misconduct of Lessor. If
any such Claim is made against Lessor, Lessee shall at its sole cost and
expense defend such Claim by or through attorneys satisfactory to Lessor. In
resolving or settling any Claim, Lessee shall obtain a release of such Claim
made against Lessor or any Lessor Related Party. The indemnity obligations of
Lessee are in addition to Lessee's obligations to obtain and maintain insurance

                                LEASE AGREEMENT


          This Lease Agreement (the "Agreement") is entered into this 18th day
of March, 1996 to be effective November 1, 1995, between KSL, a division of
Bonneville International Corporation, a Utah corporation, with its principal
place of business at Broadcast House, 55 North 300 West, P. O. Box 1160, Salt
Lake City, Utah 84110-1160 ("Lessor") and Loral Corporation, a New York
corporation, with its principal place of business at 600 Third Avenue, New
York, New York 10016 ("Lessee"), in light of the following circumstances:

                                   Recitals

          Whereas, Lessor is the owner of certain television and radio
transmission facilities located in the Oquirrh mountain range in Salt Lake and
Tooele counties, Utah at a location commonly known as Farnsworth Peak (the
"Site"); and

          Whereas, Lessee is engaged in the business of satellite
communications and data link services; and

          Whereas, Lessee desires to lease from Lessor certain space and
equipment at the Site;

          Now, therefore, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged, Lessor and Lessee agree as follows:

                             Terms and Conditions

          1. Leased Premises. Lessor hereby leases to Lessee, and Lessee hereby
accepts from Lessor, that certain space and equipment at the Site identified on
Schedule A to this Agreement (the "Premises") for the location and operation of
a test antenna of approximately six feet in length. A complete list of Lessee's
equipment to be located at the Premises (the "Equipment") is attached to this
Agreement as Schedule B.

          2.  Lessor Furnished Items.  During the term of this Agreement,
Lessor shall furnish Lessee with the following:

          A. Access to the Site over the access road available to Lessor for
     that purpose. Lessee understands that it will be subject to the same
     restrictions on the use of such road as may be imposed on Lessor from time
     to time by the entities controlling the property upon which the road is
     located, including the Kennecott Copper Corporation, Alpha
     Communications and Hercules Corporation;

          B.  Heat, light and toilet facilities at the Site;

          C. The right to connect to the power load center at the Site for the
     operation of the Equipment. Lessee's use of electricity will be separately
     metered by Lessor. Lessor shall invoice Lessee monthly for such electrical
     usage at the established commercial rates of the Utah Power and Light
     Company, plus the lesser of ten percent of Lessee's monthly statement or
     $30.00 for administration and general expenses.

                                       23

<PAGE>

     Invoices shall be payable within twenty days of the date of billing. In
     the event an invoice is more than ten days delinquent, Lessor, upon five
     days written notice, shall be entitled to cease supplying Lessee with
     electricity;

          D. Upon Lessee's request, emergency service, if available, for the
     Equipment.  Rates for emergency service are set forth in Schedule O to
     this Agreement and may be adjusted from time to time as determined by
     Lessor;

          E. The right to make reasonable alterations, attach fixtures and
     erect additions to the Premises as required to operate the Equipment, but
     only so long as plans for such alterations, attachments or additions are
     submitted, along with a list of added and/or replaced materials, to Lessor
     for approval, which approval shall not be unreasonably withheld. In no
     event shall any of Lessee's alterations, attachments or additions
     interfere with the operation or work of Lessor or of other tenants at the
     Site;

          F. Other services, such as the use of tools and parts owned by
     Lessor, at the rates listed on Schedule O, as such may be adjusted from
     time to time as determined by Lessor; and

          G. Maintenance of the Site in good operation order.

          3. Monthly Payments by Lessee. In exchange for the right to occupy
the Premises and operate the Equipment, Lessee shall pay to Lessor the monthly
rental payment and other fees set forth in Schedule C to this Agreement. The
monthly rental payment shall be payable in advance on or before the first day
of each calendar month at Lessor's principal place of business or at such other
place or in such other manner as Lessor may from time to time direct; provided,
however, that in the event the term of this Agreement shall commence on other
than the first day of a calendar month or terminate on other than the last day
of a calendar month, the monthly rental payment shall be prorated on a daily
basis for such partial calendar month. Unless otherwise specifically set forth
elsewhere in this Agreement, all other payments required to be made by Lessee
to Lessor shall be paid by within twenty days of the date of invoice.

          4. Other Costs. Lessee recognizes that additional expenses may be
incurred by Lessor from time to time for the benefit of Lessee and other
tenants at the Site, such as the cost of transporting various government
inspectors, tax assessors, state and/or county officers/officials and the like
to and from the Site. Lessee agrees to pay its share of such costs on a pro
rata basis as calculated by Lessor. Lessor shall provide Lessee with proof of
such costs, along with calculations for determining the amount charged to
Lessee.

          5. Compliance. Lessee's operations at the Site shall be in full
compliance with all applicable laws, statutes, ordinances, rules and
regulations of any governmental authority having jurisdiction over Lessor,
Lessee or the Site, including, but not limited to, the Federal Communications
Commission (the "FCC"). Lessee shall bear the cost and responsibility for all
matters pertaining to its operations at the Site, including, but not limited
to, applications, renewals, regular or special reports, discrepancy citations,
inspections or any changes in equipment which may be required from time to time
by the FCC or standards of good engineering practice.

                                       24

<PAGE>

          Lessee shall protect all persons at the Site at all times from
exposure to excessive non-ionizing radiation (as determined by the FCC, the
Occupational Safety and Health Agency, the Environmental Protection Agency or
any other governmental authority) which may be generated as a result of
Lessee's operations. In the event Lessee's operations appear to be causing
excessive non-ionizing radiation, Lessor shall have the right, but not the
obligation, to take whatever action Lessor deems appropriate to reduce the
amount of such radiation, including, but not limited to, the interruption of
Lessee's operations or the reduction of Lessee's transmission power. Lessor
shall invoice Lessee for the costs of any such action and Lessee shall promptly
pay such amount within twenty days of the date of invoice.

          6. Interference. Lessee acknowledges that Lessor reserves the right
to grant space, premises, facilities and/or rights to third parties at the Site
that are the same as or similar to those granted herein to Lessee. Lessee shall
endeavor in good faith to conduct its activities in accordance with sound
electronic and engineering practices and applicable FCC standards and will
cooperate with Lessor and other tenants at the Site so as to anticipate and
prevent Interference, as that term is defined below. A list of Tenants at the
Site as of the commencement of this Agreement is attached hereto as Schedule S.

          If Lessee's operations cause Interference, Lessee shall, at its sole
cost and expense and without recourse to Lessor, cause any such Interference to
be corrected within ten days following written notice thereof to Lessee.
Pending correction, Lessee shall immediately cease the activity or remove the
equipment causing the Interference. If Lessee fails to act within the given
time frame, Lessor may cause the required corrections to be made. Lessor shall
invoice Lessee for the costs of any such action and Lessee shall promptly pay
such amount within twenty days of the date of invoice.

          "Interference" shall be deemed to exist if (i) a final determination
to that effect is made by an authorized representative of the FCC pursuant to
its rules and regulations; (ii) a condition exists which constitutes
interference within the meaning of the provisions of the rules and regulations
of the FCC in effect at the time; or (iii) Lessor makes a good faith
determination that its technical operations or the technical operations of any
other tenants at the Site are being adversely affected by Lessee's activities.

          7. Lessor Improvements. Lessor reserves the right to replace or
install additional equipment at the Site necessary or desirable for its own
operations. Lessor shall not be liable for any disruption of or interference to
Lessee's operations by reason of such replacement or installation, but Lessor
agrees to cooperate with Lessee and to use reasonable efforts to resolve in
advance any problems that might arise in connection with these activities.

          8. Assignment or Sublease. Lessee may not assign or transfer this
Agreement or any interest therein, sublease any interest covered by this
Agreement or encumber, hypothecate or otherwise give as security this Agreement
or any interest therein without the prior written consent of Lessor, which
consent shall not be unreasonably withheld. No assignment, transfer or sublease
shall be effective as against Lessor for any purpose, unless Lessor shall have
consented thereto in writing prior to such assignment, transfer or sublease and
unless all sums due from Lessee,

                                       25

<PAGE>

together with any costs to Lessor to cover reasonable legal and other expenses
of Lessor in connection with such assignment, transfer or sublease, shall have
been paid to Lessor.

          Each and every attempt to assign, sell, transfer or encumber this
Agreement or any interest therein and each and every attempt to sublease any
interest covered hereby in a manner contrary to that set forth in this
paragraph may be deemed a default by Lessee hereunder.

          Lessor's consent to one assignment, transfer or sublease by Lessee or
acceptance of performance from an assignee, transferee or sublessee shall not
be deemed a waiver by Lessor of the restrictions of this paragraph as to
subsequent attempts to assign, transfer or sublet by Lessee or by Lessee's
heirs, successors, assigns, transferees or sublessees. As used herein, the
terms Lessor and Lessee shall be deemed to include their respective heirs,
successors, assigns, transferees or sublessees.

          The terms, conditions and covenants contained in this Agreement shall
apply to, inure to the benefit of and be binding upon the parties hereto and
their respective legal representatives, successors, assigns, transferees and
sublessees.

          Lessor shall have the right to transfer and assign, in whole or in
part, all of its rights and obligations hereunder and in the Site and in such
event Lessor shall be released from any further obligations hereunder and the
successor-in-interest of Lessor shall have all the rights and obligations
hereunder and in the Site with respect to Lessee.

          9. Term. The initial term of this Agreement shall begin on November
1, 1995 and shall end on October 31, 1996. This Agreement shall thereafter be
renewed for up to three additional two year periods (from November 1, 1996
through October 31, 1998; from November 1, 1998 through October 31, 2000; and
from November 1, 2000 through October 31, 2002, respectively) upon the same
terms and conditions set forth herein, provided Lessee gives Lessor written
notice at least ninety days prior to the expiration of the then current term.

          10.  Default by Lessee.  The following events shall be deemed to be
events of default by Lessee under this Agreement (each such event of default
is hereinafter referred to as an "Event of Default"):

          A. Lessee shall fail to timely pay any monthly rental payment as
     referenced in paragraph 3 above or any other sum of money due hereunder
     and such failure shall continue for a period of ten days after written
     notice of such default is delivered to Lessee;

          B. Lessee shall fail to comply with any provision of this Agreement
     not requiring the payment of money, all of which provisions shall be
     deemed material, and such failure shall continue for a period of twenty
     days after written notice of such default is delivered to Lessee;

          C.  Lessee shall become insolvent or fail to pay its debts as they
     become due or Lessee notifies Lessor that it anticipates either
     condition;

                                       26

<PAGE>

          D. Lessee takes any action to file a petition under any section or
     chapter of the United States Bankruptcy Code or under any similar law or
     site of the United States or any state thereof or a petition shall be
     filed against Lessee under any such statute or Lessee or any creditor of
     Lessee notifies Lessor that it knows such a petition will be filed or
     Lessee notifies Lessor that it expects such a petition to be filed; or

          E.  A receiver or trustee shall be appointed for Lessee's leasehold
     interest in the Premises or for all or a substantial part of Lessee's
     assets.

          Upon the occurrence of any Event of Default, Lessor may at its option
and without further notice to Lessee and in addition to all other remedies
given hereunder or by law or in equity, do any one or more of the following:
(i) terminate this Agreement, in which event Lessee shall immediately surrender
possession of the Premises to Lessor; (ii) enter upon the Premises and expel or
remove Lessee's Equipment therefrom, with or without having terminated this
Agreement; and (iii) change or re-key all locks to entrances to the Site and
Lessor shall have no obligation to give Lessee notice thereof or to provide
Lessee with a new key to the Site.

          The exercise by Lessor of any one or more remedies hereunder shall
not constitute an acceptance of the surrender of the Premises by Lessee. Lessee
acknowledges that a surrender of the Premises can be effected only by a written
agreement between Lessor and Lessee.

          If Lessor terminates this Agreement by reason of an Event of Default,
Lessee shall pay to Lessor the sum of (i) the cost of recovering the Premises;
(ii) the unpaid monthly payments and all other indebtedness accrued hereunder
to the date of such termination; (iii) to the extent the same were not paid,
the cost of repairing, altering or otherwise putting the Premises into a
condition acceptable to a new tenant or tenants (if Lessor elects to so relet)
(collectively, the "Reletting Expenses"); (iv) all expenses incurred by Lessor
in enforcing Lessor's remedies, including attorneys' fees and court costs; (v)
the total monthly payments and other benefits which Lessor would have received
under this Agreement for the remainder of the term, minus any net sums
thereafter received by Lessor through reletting the Premises during such
period; and (vi) any other damages or relief which Lessor may be entitled to at
law or in equity. Lessee shall not be entitled to any excess rent obtained by
reletting the Premises.

          If Lessor repossesses the Premises without terminating this Agreement
by reason of an Event of Default, then Lessee shall pay to Lessor the sum of
(i) the cost of recovering the Premises; (ii) the unpaid monthly payments and
all other indebtedness accrued hereunder to the date of such repossession;
(iii) the Reletting Expenses; (iv) all expenses incurred by Lessor in enforcing
Lessor's remedies, including attorneys' fees and court costs; (v) the total
monthly payments and other benefits which Lessor would have received under this
Agreement for the remainder of the term, minus any net sums thereafter received
by Lessor through reletting the Premises during such period; and (vi) any other
damages or relief which Lessor may be entitled to at law or in equity. Re-entry
by Lessor or will not affect the obligations of Lessee for the unexpired term
of this Agreement. Lessee shall not be entitled to any excess rent obtained by
reletting the Premises. Actions to collect amounts due by Lessee may be brought
on one or more occasions without the necessity of Lessor's waiting until the
expiration of the term of this Agreement.

                                       27

<PAGE>

          Upon termination of this Agreement or repossession of the Premises
due to an Event of Default, Lessor shall not be obligated to relet or attempt
to relet the Premises or any portion thereof or to collect rent after
reletting, but Lessor shall have the option to relet the whole or any portion
of the Premises for any period to any tenant and for any use and purpose.

for trips and from the Site. Such carriers shall carry liability insurance in
the face amount of at least $5,000,000.00 per occurrence. All such insurance
shall cover Lessee's employees, agents and invitees while in, on or about the
Site and while traveling to and from the Site, including losses attributable to
the presence of the Equipment, Lessee's employees, agents or invitees while in,

liens, judgments and expenses (including court costs, attorneys' fees and costs
of investigation) or any kind, nature or description resulting from any
injuries to or death of any person or any damage to the Site which either (i)
arises from or is claimed to arise from any act, omission or negligence of
Lessee or any employee, officer, contractor, agent, subtenant, guest, licensee
or invitee of Lessee; (ii) arises from a breach, violation or nonperformance of
any term, provision, covenant or agreement of Lessee hereunder or a breach or
violation by Lessee of any court order or any law, regulation or ordinance of
any federal, state or local authority; or (iii) arises from the activities of
Lessee in and around the Site or the operations or conduct of Lessee's business
upon the Site (collectively, the "Claims"), except to the extent such Claims
are directly caused by the gross negligence or willful misconduct of Lessor. If
any such Claim is made against Lessor, Lessee shall at its sole cost and
expense defend such Claim by or through attorneys satisfactory to Lessor. In
resolving or settling any Claim, Lessee shall obtain a release of such Claim
made against Lessor or any Lessor Related Party. The indemnity obligations of
Lessee are in addition to Lessee's obligations to obtain and maintain insurance
as otherwise provided herein.

          Lessee specifically agrees to look solely to Lessor's interest in the
Site for the recovery of any judgment against Lessor.

          13.  Limits on Liability.  Lessor shall have no liability to Lessee
or any other party for any loss allegedly occasioned by the nontransmission

or greater than $500.00.

          17. Road Maintenance Charge. Lessee acknowledges and agrees that an

          B. The Assignee is acquiring certain assets and assuming certain
liabilities from the Assignor including the Assignor's rights, leasehold
interest and obligations under the Lease.

          C. In connection with such acquisition, the Assignor desires to
assign the Lease to the Assignee, and the Assignee desires to accept the
assignment of the Lease from the Assignor.

          D. The Landlord has agreed to enter into this Assignment to, among

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

          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

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

                 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

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

                 22.  Lessor's Inability to Perform.

                 22.1. This Lease and the obligation of Lessee to pay Rent
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
any equipment or fixtures, if Lessor is prevented or delayed from so doing by
reason of strikes or labor trouble or by accident, adjustment of insurance or
by any cause whatsoever reasonably beyond Lessor's control, including but not
limited to, laws, governmental preemption in connection with a national
emergency or by reason of any rule, order or regulation or any federal,

which have been or are affected by war or other emergency.

                 23.  Limitations or Liability.

                 23.1. It is specifically understood and agreed that there
shall be absolutely no personal liability on the part of Lessor in respect of
any of the terms, covenants and conditions of this Lease, and Lessee shall look
solely to the interest of Lessor in the Demised Premises for the satisfaction
of each and every remedy of Lessee in the event of any breach or default by
Lessor, or by any successor in interest to Lessor, of any of the terms,
covenants and conditions of this Lease to be performed by Lessor.

                 23.2. Nothing in this Section is intended to limit or affect
any obligations of Lessor or any affiliate of Lessor which are contained in any
separate agreement.

                 24.  Asset Purchase Agreement.

                 24.1. Notwithstanding anything to the contrary contained
herein, in the event of a conflict between the terms of this Lease and the
terms of the Asset Purchase Agreement, the terms of the Asset Purchase
Agreement shall govern.

                 24.2. As used herein, (a) the term "Asset Purchase Agreement"

Unisys Corporation and Loral Corporation, as amended from time to time, and (b)

                 25.3. If any of the provisions of this Lease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such provision or provisions to persons or circumstances other than those as to
whom or which it is held invalid or unenforceable, shall not be affected
thereby, and every provision of this Lease shall be valid and enforceable to
the fullest extent permitted by law.

                 25.4. All of the terms and provisions of this Lease shall be
binding upon and inure to the benefit of the parties hereto and, subject to the

                                     RIDER

                 1. This Rider is a part of this Lease. In the event of any
contradiction or inconsistency between the provisions of this Rider and the
provisions of the other portions of this Lease, the provisions of this Rider
shall govern and prevail, and the contradicting and inconsistent provisions of
the other portions of this Lease shall be deemed amended accordingly.

                 2. Lessee (together with its employees, licensees, and
invitees) shall have the non-exclusive right to use the 280 parking spaces at
the Property designated on Schedule B to this Lease.

                 3. Lessee hereby agrees to provide the services described on
Schedule D-1 attached hereto, which services were previously provided by
Lessor's non-Defense Systems personnel, to the Demised Premises during the Term
hereof. In connection therewith, Lessor and Lessee shall share supplies and
equipment located at the Property for performance of their respective service
obligations with respect to the Property until the exhaustion of such supplies
and equipment. Thereafter, Lessor and Lessee shall separately purchase and use
such supplies and equipment as each may determine it requires for performance
of its respective service obligations.

                 4. With respect to contracts entered into by Lessor prior to
the date of this Lease relating in whole or in part to the provision of
services to the Demised Premises, which services Lessee has assumed the
obligation to provide as of the date of this Lease and which services were
previously provided by Lessor's non-Defense Systems personnel, (a) Lessor shall
endeavor to terminate such contracts at the earliest possible time, provided
Lessor shall not be obligated to breach such contracts and (b) Lessee shall be
obligated to pay all sums due under such contracts for the provision of goods
and services to the Demised Premises.

                 5. From the date hereof until the earlier of (a) the

to terminate receipt of such services, Lessee shall continue to provide
security services to the portions of the Property not part of the Demised
Premises, of the type generally and customarily provided by Lessor's Defense
Systems unit to the Property prior to the date hereof.

December 31, 2001.

                 As used in this Lease, "Base Rent" shall mean, with respect to
any calendar month, all actual costs and expenses relating to the Property
(including common areas and facilities) that are allocated by Lessor to the
Demised Premises for such month, provided that Lessor's method of allocation
shall be consistent with the method of allocation used by Unisys Corporation to
allocate costs to the Unisys Defense Systems unit with respect to the occupancy
of the Demised Premises by the Unisys Defense Systems unit during calendar year
1994. Such costs and expenses shall include cash items and non-cash items, such
as depreciation. In the event that Base Rent for any calendar quarter (as
calculated above) shall not be determinable by Lessor until after the end of
such calendar quarter, then Base Rent shall be payable during such calendar
quarter based upon Lessor's reasonable estimate of costs and expenses to be
allocated to the Demised Premises. Lessor shall, as soon as practicable after
the end of such calendar quarter, provide Lessee with a written statement of
the Base Rent amount for such calendar quarter and, subject to Section 3.5 of
the Lease, the parties shall promptly thereafter make any necessary
reconciliation payments.

                                   RECITALS

          A. The Landlord, as landlord, and the Assignor, as tenant, executed a
Sublease Agreement dated May 5, 1995, (which, together with all modifications,
amendments and supplements thereof, is hereinafter referred to collectively as
the "Sublease"), a copy of which is attached hereto and incorporated by
reference as Exhibit A, pursuant to which Landlord subleased to the Assignor
and the Assignor subleased from Landlord property and improvements described
therein located in Salt Lake City, Utah, (Buildings E and F) (the "Premises").

          B. The Assignee is acquiring certain assets and assuming certain
liabilities from the Assignor including the Assignor's rights, leasehold
interest and obligations under the Sublease.

          C.  In connection with such acquisition, the Assignor desires to
assign the Sublease to the Assignee, and the Assignee desires to accept the
assignment of the Sublease from the Assignor.

          D.  The Landlord has agreed to enter into this Assignment to, among
other things, evidence its consent to such assignment of the Sublease.

          NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the Assignor, the Assignee and the
Landlord hereby covenant and agree as follows:

          1. Assignment. The Assignor grants, assigns and transfers to the
Assignee, its successors and assigns, all of the Assignor's right, title and
interest in, to and under the Sublease (including, without limitation, any
options under the Sublease and any rights to extend or renew the Sublease) and
the Assignee accepts from the Assignor all of the Assignor's right, title and
interest in, to and under the Sublease.

          2.  Assumption of Sublease Obligation.  The 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
Sublease, including, without limitation, the obligation to make all payments
due or payable on behalf of the Assignor under the Sublease 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 Sublease attached hereto as Exhibit A is a true, correct and
complete copy of the Sublease (including all modifications, amendments

                                       1

<PAGE>

and supplements thereof) and the same are the only agreements between Landlord
and the Assignor with respect to the subject matter thereof.

          (b) The Sublease is in full force and effect and, except for the
modifications, amendments and supplements included in Exhibit A, the Sublease
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 Sublease, 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) and a security deposit in the amount of $0.00
has been paid to the Landlord.

          (e) The monthly amount of base rent due under the Sublease as of May
1, 1997, is $221,500 and the minimum or base rent and all other rentals and
other payments due, owing and accruing under the Sublease have been paid
through April 30, 1997.

          (f) The term of the Sublease commenced on May 5, 1995, and the
current term of the Sublease expires on December 31, 2001.

          4. Landlord's Consent. The Landlord hereby consents to the Assignor's
assignment of the Sublease to the Assignee and the Assignee's assumption of the
Sublease. Landlord's consent to the Assignor's assignment of the Sublease to
the Assignee shall not be deemed to release the Assignor from any of its
obligations under the Sublease or to alter any provision of the Sublease and/or
the primary liability of the Assignor for the payment of minimum or base rent
or any additional rent due under the Sublease or for the performance of any
other obligations to be performed by the Assignor under the Sublease.

          5. Successors and Assigns. This Assignment shall be binding on and
inure to the benefit of the parties hereto, and their respective heirs,
personal representatives, successors and assigns, provided that this Section 5
shall not be construed to permit any future assignments of the Sublease or
subletting of the Premises except as permitted by the Sublease.

          6.  Counterparts.  This Assignment may be signed in counterpart
and, as 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.

                 SUBLEASE, 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 ("Sublessor") and LORAL CORPORATION, a New
York corporation having an office at 600 Third Avenue, New
York, New York 10016 ("Sublessee").

                             W I T N E S S E T H :

                 WHEREAS, the landlord under the Master Lease described on
Schedule A hereto (the "Landlord") is the owner of the real property (including
improvements) described on such Schedule A (collectively, the "Property"), and
under the Master Lease the Landlord has leased to Sublessor certain premises at
the Property; and

                 WHEREAS, Sublessor desires to sublet to Sublessee, and
Sublessee desires to hire from Sublessor, a portion of the premises demised
under the Master Lease upon the terms and conditions hereinafter set forth;

                 NOW, THEREFORE, in consideration of the mutual covenants
hereinafter provided, Sublessor and Sublessee hereby agree as follows:

                 1.  Demised Premises.

                 1.01. Sublessor hereby sublets to Sublessee, and Sublessee
hereby sublets and hires from Sublessor, 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 sublease 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 Sublease by reference.

                 1.02. Sublessee agrees to accept the Demised Premises on the
Commencement Date (as hereinafter defined) in its "as is" condition and
Sublessor 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 Sublessee or otherwise. Sublessee hereby releases Sublessor
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 Sublessor or any
affiliate of Sublessor may have to Sublessee or any affiliate of Sublessee
which arises under any of the other terms and conditions of this Sublease or
under the terms and conditions of any other agreement. Sublessee acknowledges
that, except as expressly set forth herein or as expressly set forth in any
separate document, Sublessor has made no statements, representations, covenants
or warranties with respect to (x) the condition or

                                       7

<PAGE>

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 to the Property or the Demised Premises. Sublessee
also agrees that, in executing this Sublease, 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 Sublease or in any
other separate agreements by or between Sublessor and/or Sublessee or any of
their respective affiliates.

                 2.  Term.

                 2.01. (a) The term of this Sublease 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 Sublease,
(i) "Term" shall mean the term of this Sublease, and (ii) "Expiration Date"
shall mean the Scheduled Expiration Date, as defined in Schedule C hereto;
provided that (A) in no event shall the Expiration Date occur later than 11:59
p.m. on the day immediately preceding the expiration of the term of the Master
Lease, and (B) in the event of a termination of this Sublease pursuant to the
terms hereof prior to the Scheduled Expiration Date, the "Expiration Date"
shall mean such date of termination of this Sublease.

                 (b) Notwithstanding anything to the contrary in this Sublease,
the Term shall be immediately terminated if the term of the Master Lease is
terminated for any reason prior to the Scheduled Expiration Date.

                 (c) References in this Sublease to the "termination" of this
Sublease include the stated expiration of the Term and any earlier termination
thereof pursuant to the provisions of this Sublease, or the Master Lease or by
law. Except as otherwise expressly provided in this Sublease with respect to
those obligations of Sublessee which by their nature or under the circumstances
can only be, or under the provisions of this Sublease may be, performed after
the termination of this Sublease, the Term and estate granted hereby shall end
at noon on the date of termination of this Sublease 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 Sublessor or Sublessee to make any payment under this
Sublease, including, without limitation, amounts payable by Sublessee as Base
Rent or Additional Rent hereunder (both as hereinafter defined), which shall
have accrued prior to the termination of this Sublease shall survive the
termination of this Sublease.

                 3.  Rent.

                 3.01.  The rent ("Rent") payable during the Term under this
Sublease 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 Sublessee to Sublessor under this Sublease.

                                       8

<PAGE>

                 3.02. Except as otherwise specifically provided in this
Sublease (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 Sublessor in accordance with Schedule C hereof, then Sublessor
shall give Sublessee 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 Sublessor, 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 Sublessor may from time to time designate in writing.

                 3.03. Sublessee 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
Sublessor or Sublessee pursuant to the terms of this Sublease 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 Sublessee 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 Sublease.

                 3.04. Sublessee agrees to pay, as 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 Sublessee's use or
occupancy thereof during the Term; provided, however, that in no event shall
Sublessee be obligated to pay any income tax that is imposed upon and/or
payable by Sublessor, and provided further that payments made by Sublessee
pursuant to this Section 3.4 shall not be duplicative of amounts paid by
Sublessee pursuant to any other provision of this Sublease.

                 3.05. In the event that Sublessee shall dispute any
calculation of Rent charged to Sublessee by Sublessor, then Sublessee shall
send to Sublessor a written notice, within 30 days of receipt by Sublessee of
such charge, setting forth the basis for Sublessee's dispute. Sublessor and
Sublessee 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 Sublessee 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 Sublessor
and Sublessee. 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 3.7 below.

                 3.06.  Sublessor shall furnish to Sublessee copies of any
material statements and other material documents and information which are

                                       9

<PAGE>

provided to Sublessor by Landlord pursuant to the Master Lease. Without
limiting any other obligations of Sublessor hereunder, Sublessor agrees it
will, upon reasonable request from Sublessee, exercise on Sublessee's behalf,
and at Sublessee's sole cost, any rights of Sublessor under the Master Lease to
review and inspect records and otherwise obtain information from Landlord.

                 3.07. All calculations by Sublessor of Base Rent, Additional
Rent and any other amounts that are payable by Sublessee hereunder shall be
made in accordance with Sublessor'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 Sublessor with
respect to amounts charged to Sublessee under this Sublease (including the
capitalization, amortization and expensing of costs incurred and funds
expended) shall also be made in such manner.

                 4.  Use.

                 4.01. Sublessee shall occupy and use the Demised Premises only
for the uses permitted under the Master Lease and for no other purpose, and in
all respects only as permitted under the terms and provisions of this Sublease
and the Master Lease, and in accordance with any and all laws, statutes,
ordinances, orders, regulations and requirements of all federal, state and
local governmental, public or quasipublic 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 Sublease affecting the Demised
Premises (collectively, "Legal Requirements").

                 5.  Master Lease.

                 5.01. Subject to Section 5.3 below, this Sublease and all of
Sublessee's rights hereunder are and shall remain in all respects subject and
subordinate to (i) all of the terms and provisions of the Master Lease, a true
and complete copy of which has been delivered to and reviewed by Sublessee,
(ii) any and all amendments to the Master Lease or supplemental agreements
relating thereto hereafter made between Landlord and Sublessor and (iii) any
and all matters to which the tenancy of Sublessor, as tenant under the Master
Lease, is or may be subordinate. Sublessee shall in no case have any rights
under this Sublease greater than Sublessor's rights as tenant under the Master
Lease. The foregoing provisions shall be self-operative and no further
instrument of subordination shall be necessary to effectuate such provisions
unless required by Landlord or Sublessor, in which event Sublessee shall, upon
demand by Landlord or Sublessor at any time and from time to time, execute,
acknowledge and deliver to Sublessor and Landlord any and all instruments that
Sublessor or Landlord, in the reasonable discretion of either of them, may deem
necessary or proper to confirm such subordination of this Sublease, and the
rights of Sublessee hereunder, subject to Section 5.3(a) hereof.

                 5.02. Sublessee agrees that it shall neither act, nor omit to
act, in such a manner as to result in a default under the Master Lease,
provided that in no event shall Sublessee be responsible for acts and omissions
of Sublessor or Sublessor's agents, employees or contractors. Except as
otherwise specifically provided in the next sentence and elsewhere in this
Sublease, (i) all of the terms, covenants, conditions and agreements which
Sublessor is required to observe or perform with respect to the Demised
Premises as tenant under the Master Lease are hereby incorporated herein by

                                       10

<PAGE>

reference and Sublessee shall observe and perform all of such terms, covenants,
conditions and agreements as if such terms, covenants, conditions and
agreements were set forth herein at length, and (ii) Sublessor may exercise all
of the rights, powers, privileges and remedies reserved to Landlord under the
Master Lease to the same extent as if fully set forth herein at length,
including, without limitation, all rights and remedies arising out of or with
respect to any default by Sublessee in the payment of Rent hereunder or the
observance or performance of the terms, covenants, conditions and agreements of
this Sublease and the Master Lease (except as specifically provided herein).
The terms and conditions of the Master Lease described on Schedule D hereto
shall not be incorporated herein by reference, nor shall any terms or
conditions of the Master Lease that, by their terms, are inapplicable to, or
inconsistent with this Sublease, be incorporated by reference herein. In
amplification of, and not in limitation of, the foregoing, in no event shall
any rights or options under the Master Lease to renew or extend the term
thereof be incorporated by reference in this Sublease for the benefit of
Sublessee. Notwithstanding the foregoing, any inconsistencies between the terms
of the Master Lease incorporated by reference hereunder and the other terms of
this Sublease or any of the Transaction Documents (as hereinafter defined)
shall be resolved in favor of such other terms of this Sublease or the terms of
the Transaction Documents, provided, however, that if such construction of
terms would cause Sublessor to be in default under the terms of the Master
Lease, then such inconsistency shall be resolved in favor of the Master Lease.
In addition, in the event that Sublessor is in default of any of its
obligations under the Master Lease as of the date hereof and such obligation is
not a DS Liability (as defined in the Asset Purchase Agreement), then Sublessee
shall not be required to cure such default by virtue of the incorporation by
reference provisions of this Sublease.

                 5.03. Sublessor agrees that it shall neither act, nor omit to
act, in such a manner as to result in a default under the Master Lease,
provided that in no event shall Sublessor be responsible for acts and omissions
of Sublessee or Sublessee's agents, employees or contractors. Provided that
Sublessee is not then in default under the terms of this Sublease beyond
applicable grace periods, Sublessor agrees that, during the Term hereof,
without the prior written consent of Sublessee, which consent shall not be
unreasonably withheld or delayed, Sublessor will not (a) consent to a
termination of the Master Lease (to the extent that Sublessor's consent is
required pursuant to the Master Lease) or amend or modify the Master Lease in
any way which would materially reduce, materially interfere with or otherwise
materially impair any rights, powers or remedies of Sublessee, decrease in any
material respect the obligations of Landlord or Sublessor which, under the
terms of this Sublease, run to the benefit of Sublessee or increase the
monetary obligations of Sublessee or increase in any material respect any other
obligations of Sublessor for which Sublessee is responsible hereunder, or (b)
consent (in the event that Sublessor's consent is required pursuant to the
Master Lease) to the subordination of the Master Lease to any mortgage,
underlying lease or similar instrument. Notwithstanding the foregoing, in no
event shall Sublessor be required under this Sublease to exercise any renewal
or extension option set forth in the Master Lease.

                 5.04. Notwithstanding anything to the contrary contained
herein, in the event of a conflict between the terms of this Sublease and the
terms of the Asset Purchase Agreement, the terms of the Asset Purchase
Agreement shall govern.

                                       11

<PAGE>

                 5.05. As used herein, (a) the term "Asset Purchase Agreement"
shall mean the Asset Purchase Agreement, dated as of March 20, 1995, between
Unisys Corporation and Loral Corporation, as amended from time to time, and (b)
the term "Transaction Documents" shall mean all agreements between Sublessor
and Sublessee executed pursuant to, or in connection with, the Asset Purchase
Agreement other than this Sublease.

                 6.  Services.

                 6.01. It is the intent of the parties that Sublessor shall
continue to provide to Sublessee all services, utilities, repairs and
facilities 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 E hereto, and
such Services shall not include any of those items set forth on Schedule E-1
hereto. Sublessee shall pay to Sublessor, in consideration for the Services and
as Additional Rent, an amount equal to Sublessor's actual costs to perform such
Services in, to or for the benefit of the Demised Premises or Sublessee, which
shall be determined in accordance with the principles set forth in Section 3.7
above ("Actual Costs"). On a quarterly basis, Sublessor shall provide to
Sublessee a written statement, in reasonable detail, setting forth such Actual
Costs for Services. In the event that Sublessee disputes Sublessor's statement
of Actual Costs, such dispute shall be resolved in accordance with Section 3.5
hereof.

                 6.02. It is the intent of the parties that Sublessee shall
continue to provide to Sublessor, during the Term hereof, all reasonable
services generally and customarily provided by Defense Systems, prior to the
Commencement Date, to the other portions of the Property leased by Sublessor
under the Master Lease. Sublessee shall perform such services, and Sublessor
shall pay to Sublessee a proportionate share of Sublessee's actual costs
incurred in performing such services. On a quarterly basis, Sublessee shall
provide to Sublessor 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.

                 6.03. In the event that telephone switching equipment or other
telecommunications equipment utilized by Sublessor or Sublessee 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.

                 6.04.  The provisions of this Section shall survive the
expiration or earlier termination of this Sublease.

                 7.  Alterations and Repairs; Demising Costs; Signage.

                 7.01. 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
Sublessor in each instance, which consent shall not be unreasonably withheld,
conditioned or delayed, Sublessee shall not make any (a) structural

                                       12

<PAGE>

Alterations or (b) non-structural Alterations having a design and construction
cost in excess of $100,000 on a per project basis. Any Alterations consented to
by Sublessor, or otherwise permitted under this Sublease, shall be performed by
Sublessee, at its sole cost and expense, and in compliance with all of the
provisions of the Master Lease, including the provisions requiring Landlord's
prior written consent, and such other reasonable requirements of Sublessor.
Sublessor shall have the right to post notices of non-responsibility and
similar notices, as Sublessor shall reasonably deem appropriate, on the Demised
Premises while Alterations are occurring.

                 7.02. Sublessor shall have no obligations whatsoever to
Sublessee to make any repairs (except to the extent provided in Schedule E and
Schedule E-1 hereto) or Alterations in the Demised Premises to any systems
serving the Demised Premises or to any equipment, fixtures or furnishings in
the Demised Premises, or to comply with any violations of law with respect
thereto, or to restore the Demised Premises in the event of a fire or other
casualty therein or to perform any other duty with respect to the Demised
Premises which Landlord is required to perform under the Master Lease. Subject
to Section 6.2 and 6.3 hereof and Schedule E and Schedule E-1 hereto, Sublessee
shall look solely to Landlord for the making of any and all repairs in the
Demised Premises and the performance of any and all such other work and
responsibilities and only to the extent required by the terms of the Master
Lease.

                 7.03. Sublessor and Sublessee 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 Sublessor. In the event that the parties
reach such a mutual agreement, then Sublessor shall perform such agreed upon
Alterations, and Sublessee shall, within thirty (30) days after written demand
by Sublessor, reimburse Sublessor for one-half of the costs and expenses
relating to such Alterations. Sublessor may request payment of Sublessee's
share of such costs, and (if requested) Sublessee shall pay its share of such
costs, as such costs are incurred by Sublessor during the course of design and
construction of such Alterations. Sublessor 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
Sublessor, Sublessee and Landlord as additional insureds.

                 7.04. Sublessee 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 Sublessee'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 Sublessor, which consent shall not
be unreasonably withheld or delayed.

                 7.05. Sublessee shall indemnify and hold harmless Sublessor
and Landlord from all costs, expenses, liabilities and obligations arising out
of the filing of any mechanic's or materialman's lien against the Demised
Premises by reason of any act or omission of Sublessee.

                 7.06.  In the event that the Demised Premises are measured
or re-measured pursuant to the terms of this Sublease (inclusive of the
Rider, if any, and Schedules attached hereto), Sublessor and Sublessee shall

                                       13

<PAGE>

each pay one-half (1/2) of the costs and expenses relating to such measurement
or re-measurement.

                 8.  Insurance.

                 8.01. Sublessee, at Sublessee's sole expense, shall maintain
for the benefit of Sublessor and Landlord such policies of insurance (and in
such form) as are required by the Master Lease with respect to the Demised
Premises which shall be reasonably satisfactory to Sublessor 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
Sublessor, Landlord and Sublessee against any and all claims and liabilities
for injury or damage to persons or property occurring 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 Sublessee or
Sublessee's employees, agents or invitees. Sublessor and Landlord shall each be
named as an additional insured under any such policies of insurance obtained by
Sublessee, 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 Sublessee's failure to pay the
premium for such insurance) shall have been given by the applicable insurance
company to Sublessor and Landlord. Upon execution of this Sublease by Sublessee
and at least thirty (30) days prior to the expiration date of such policies,
Sublessee shall furnish to Landlord and Sublessor 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 Sublessee 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 Sublessee.

                 8.02. Nothing contained in this Sublease shall relieve
Sublessee 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, Sublessor and Sublessee 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 Sublessor and Sublessee 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.

                 9.01. Sublessee shall not sublease or mortgage, pledge or
otherwise encumber all or any part of the Demised Premises, assign or mortgage
this Sublease (by operation of law or otherwise) or permit the Demised Premises
to be used or occupied by anyone other than Sublessee, Sublessee's divisions
and other Affiliates, and Sublessee's licensees, invitees, customers and
vendors, without the prior written consent of Sublessor in each instance, which
consent shall not be unreasonably withheld,

                                       14

<PAGE>

conditioned or delayed; provided, however, that Sublessee, upon at least 30
days prior written notice to Sublessor and upon Sublessee's obtaining any
required consent of Landlord under the Master Lease, may assign this Sublease
or sublet all or part of the Demised Premises to (A) an Affiliate of Sublessee,
(B) an entity into which Sublessee is merged or consolidated, and (C) an entity
which acquires all or substantially all of the business or operations of
Sublessee. Any consent by Sublessor and/or Landlord as hereinabove required
shall not excuse Sublessee from its obligation to obtain the express written
consent of Sublessor and/or Landlord to any further action or matter with
respect to which the consent of Sublessor and Landlord is hereinabove required
and Sublessee 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.  Default.

                 10.01.  (a)  Each of the following shall constitute an Event
of Default hereunder:

                      (i)   if Sublessee shall fail to pay when due any Rent
or any other amount Sublessee may be required to pay hereunder, and Sublessee
shall fail to remedy such default within seven (7) business days after written
notice thereof has been given to Sublessee by Sublessor, provided that any
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)  subject to Section 10.1(b) below, if Sublessee
shall default in the observance or performance of any term, covenant or
condition of this Sublease on Sublessee'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 Sublessee 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 Sublessee's control it
cannot be completely remedied within said period of thirty (30) days, then if
Sublessee (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 Sublease 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
Sublessee, and Sublessee shall fail to remedy such default within sixty (60)
days after written notice thereof has been given to Sublessee by Sublessor;

                 (b) Upon the occurrence of any such Event of Default,
Sublessor may, in addition to exercising any other available rights or
remedies, give to Sublessee 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 Sublease and the Term and estate hereby
granted (whether or not the Term shall have commenced) 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 Sublessor and Sublessee shall
remain liable for the performance of their respective obligations hereunder
which survive the termination of this Sublease and for damages as provided in
this Sublease.

                                       15

<PAGE>

                 10.02. Notwithstanding anything to the contrary set forth
herein, this Sublease shall immediately terminate if any of the following
events shall occur with respect to Sublessee: (a) if Sublessee shall (i) have
applied for or consented to the appointment of a receiver, trustee or
liquidator, or other custodian of Sublessee, 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 Sublessee, 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 Sublessee, 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 Sublessee, nor any person claiming through or
under Sublessee 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, Sublessee is
permitted to assign this Sublease, Sublessee 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 Sublease.

                 10.03. In the event of any breach by Sublessee or any persons
claiming through or under Sublessee of any of the terms, covenants or
conditions contained in this Sublease, Sublessor, after the giving of any
notice required by the terms of this Sublease 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 10.3 shall
survive the expiration or sooner termination of this Sublease.

                 10.04. If this Sublease and the Term shall terminate as
provided in Section 10.1 or in Section 10.2 above, or by or under any summary
proceeding or any other action or proceeding or if Sublessor 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) Sublessee shall pay to Sublessor all Base Rent, Additional
Rent and other amount payable by Sublessee hereunder to the date upon which
this Sublease and the Term shall have terminated or to the date of re-entry
upon the Demised Premises by Sublessor, as the case may be;

                 (b)  Sublessor shall be entitled to retain all monies, if
any, paid by Sublessee to Sublessor, whether as advance Rent, security or

                                       16

<PAGE>

otherwise, but such monies shall be credited by Sublessor against any Rent due
at the time of such termination or re-entry or, at Sublessor's option, against
any damages payable by Sublessee;

                 (c) Sublessee shall be liable for and shall pay to Sublessor,
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 Sublessor by Sublessee pursuant to Section 6.2 above) and the net
amount, if any, of rents ("Net Rent") collected under any reletting effected
pursuant to the incorporation herein of any provision of the Master Lease for
any part of such period (after first deducting from the rents collected under
any such reletting all of Sublessor's reasonable expenses in connection with
the termination of this Sublease or Sublessor'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 Sublessor shall not have collected any
monthly deficiencies as aforesaid, Sublessor shall be entitled to recover from
Sublessee, and Sublessee shall pay to Sublessor, 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 6.2 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 Sublessor 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 Sublessee be entitled to receive any
excess of Net Rent over the sums payable by Sublessee to Sublessor hereunder,
and in no event shall Sublessee 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 Sublessor prior to the
commencement of such suit.

                 10.05. Nothing herein contained shall be construed as limiting
or precluding the recovery by Sublessor against Sublessee of any sums or
damages to which, in addition to the damages particularly provided above,
Sublessor may lawfully be entitled by reason of any default hereunder or under
the terms of the Master Lease incorporated herein on the part of Sublessee;
provided, however, that notwithstanding any provision of the Master Lease or
the Sublease to the contrary, in no event shall Sublessor or Sublessee be
entitled to special or consequential damages with respect to any matter arising
hereunder or relating hereto.

                 11.  Indemnification.

                 11.01. Sublessee shall indemnify and hold harmless Sublessor
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 Sublessee or for any damage to, or loss (by theft or otherwise) of,
any of the property of Sublessee, irrespective of the cause of such injury,
damage or loss and whether occurring in or about the Demised Premises or the
Property.

                 11.02. Sublessee shall indemnify and hold harmless Sublessor
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 Sublessee in the observance or performance of, or compliance
with, any of the terms, covenants or conditions of this Sublease or the terms
of the Master Lease incorporated herein on Sublessee'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 Sublessee or any of its agents, employees
or contractors, or the exercise by Sublessee or any of its agents, employees or
contractors, of any rights granted to Sublessee hereunder, (c) any acts,
omissions or negligence of Sublessee 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 Sublease or (d) the condition of the
Demised Premises, but only to the extent that Sublessee 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 Sublessor by
reason of any such claim, Sublessee shall be given prompt notice thereof and,
upon notice from Sublessor, shall resist and defend such action or proceeding
at Sublessee's sole expense and employ counsel therefor reasonably satisfactory
to Sublessor. Sublessee shall pay to Sublessor on demand all sums which may be
owing to Sublessor by reason of the provisions of this subsection. Sublessee's
obligations under this subsection shall survive the Expiration Date or earlier
termination of this Sublease.

                 11.03. Sublessor shall indemnify and hold harmless Sublessee
and Sublessee'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 party claims, suits or proceedings, incurred in connection with or
arising from (a) any default by Sublessor in the observance or performance of,
or compliance with, any of the terms, covenants or conditions of this Sublease
or the Master Lease on Sublessor's part to be observed, performed or complied
with, or (b) the gross negligence or wilful misconduct of Sublessor (in its
capacity as sublessor hereunder) or any of its agents, employees or contractors
(retained by Sublessor in its capacity as sublessor hereunder), in or about the
Demised Premises or the Property either prior to, during, or after the
termination of this Sublease. If any action or proceeding shall be brought
against Sublessee by reason of any such claim, Sublessor shall be given prompt
notice thereof and, upon notice from Sublessee, shall resist and defend such
action or proceeding at Sublessor's

                                       18

<PAGE>

sole expense and employ counsel therefor reasonably satisfactory to Sublessee.
Sublessor shall pay to Sublessee on demand all sums which may be owed to
Sublessee by reason of the provisions of this subsection. Sublessor's
obligations under this subsection shall survive the Expiration Date or earlier
termination of this Sublease.

                 11.04. Sublessor shall not be liable for any loss or damage to
property of Sublessee or any of its employees, guests, invitees or licensees by
reason of theft or otherwise. Sublessor 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
Sublessor, its affiliates, or the officers, directors, employees or agents of
Sublessor or its affiliates in the course of their employment. Subject to the
foregoing, all property of Sublessee or others kept or stored on the Demised
Premises shall be so kept or stored at the risk of Sublessee only.

                 11.05. Notwithstanding anything in this Section 11 to the
contrary, neither party shall be required to indemnify the other party (an
"indemnitee") against the indemnitee's own negligence or wilful misconduct.

                 12.  Hazardous Materials.

                 12.01. Sublessee 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 Sublessee, except in
full compliance with applicable Legal Requirements. If Sublessee 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
Sublessee (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 Sublessee is legally, actually or factually liable or responsible (other
than liability which arises solely as a result of the subtenancy created hereby
or solely as a result of Sublessee's mere occupancy of the Demised Premises),
then Sublessee shall fully and completely indemnify, defend and hold harmless
Sublessor (or any party claiming by, through or under Sublessor) 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, reasonable attorneys' fees,
consultants fees and expert fees which arise or arose before, during or after
the term of this Sublease 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 Sublessee is
responsible pursuant to the terms of this Sublease. Without limiting the
foregoing, if the introduction or release of any Hazardous Materials on,

                                       19

<PAGE>

under or about the Demised Premises or any other surrounding area(s) caused or
permitted by Sublessee (or the aforesaid others) results in any contamination
of the Demised Premises, Sublessee 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 Sublessee of any such
Hazardous Materials thereto; provided that the prior written approval (which
approval shall not be unreasonably withheld, conditioned or delayed) of such
actions by Sublessor shall be first obtained. The foregoing obligations and
responsibilities shall survive the expiration or earlier termination of this
Sublease.

                 12.02. 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.

                 12.03. Sublessor and Sublessee 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.

                 13.  Remedies Cumulative.

                 13.01. Each right and remedy of Sublessor under this Sublease
shall be cumulative and be in addition to every other right and remedy of
Sublessor under this Sublease and now or hereafter existing at law or in
equity, by statute or otherwise.

                 14.  Quiet Enjoyment.

                 14.01. Sublessor covenants that, as long as Sublessee shall
pay the Base Rent and Additional Rent and all other amounts Sublessee shall be
required to pay hereunder and shall duly observe, perform and comply with all
of the terms, covenants and conditions of this Sublease on its part to be
observed, performed or complied with, Sublessee shall, subject to all of the
terms of the Master Lease and this Sublease, peaceably have, hold and enjoy the
Demised Premises during the Term without molestation or hindrance by Sublessor.

                 15.  Release of Sublessor.

                 15.01. The term "Sublessor", as used in this Sublease so far
as covenants or obligations on the part of Sublessor are concerned, shall be
limited to mean and include only the owner or owners at the time in question of
the tenant's interest under the Master Lease, and in the event of any transfer
or transfers of the tenant's interest in the Master Lease,

                                       20

<PAGE>

Sublessor herein named (and in case of any subsequent transfer or conveyance,
the then transferor of the tenant's interest in the Master Lease) 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 Sublessor contained in this Sublease thereafter to be performed;
provided, however, that no Sublessor shall be freed or relieved from any of its
obligations or liabilities hereunder which first arise or accrue prior to the
transfer of such Sublessor's interest as tenant under the Master Lease.

                 16.  Surrender of Demised Premises.

                 16.01. Sublessee shall, no later than the termination of this
Sublease and in accordance with all of the terms of this Sublease and the
Master Lease (including, without limitation, any restoration obligations in the
Master Lease that are applicable to the Demised Premises and are incorporated
by reference herein), vacate and surrender to Sublessor 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 Sublessee is not responsible,
and other items the repair or remediation of which is the responsibility of
Sublessor or Landlord excepted. Tenant's obligation to observe or perform this
covenant shall survive the termination of this Sublease.

                 16.02. 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 Sublessee 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 plus any
amounts charged against Sublessor as lessee under the Master Lease for holdover
rent or penalty. It is further agreed that Sublessee shall indemnify and hold
harmless Sublessor from and against any and all liability, claims, demands,
expenses, damages and judgments (other than consequential or special damages)
incurred by Sublessor as a result of Sublessee's retaining possession, which
indemnification obligation shall survive the Expiration Date.

                 17.  Notices.

                 17.01. All notices, consents, approvals or other
communications (collectively, a "Notice") required to be given under this
Sublease 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 the following addresses (unless such address shall be changed by
Notice from one party to the other):

                 To Sublessor:

                 Unisys Corporation
                 P.O. Box 500
                 Blue Bell, PA  19424
                 Attention:  Real Estate Administration

                                       21

<PAGE>

                 To Sublessee:

                 Loral Corporation
                 600 Third Avenue
                 New York, NY  10016
                 Attention:  Vice President/General Counsel

Any Notice given pursuant hereto shall be deemed to have been given and shall
be effective when received, or when delivered and refused.

                 18.  Landlord Consents During Term.

                 18.01. Wherever in this Sublease the consent or approval of
Sublessor is required for any act or thing, Sublessor agrees that it shall not
unreasonably withhold, condition or delay such consent or approval. If the
consent or approval of Landlord is required under the Master Lease for the same
act or thing, if Sublessor is required or willing to give its consent or
approval to Sublessee when such consent or approval is required hereunder,
Sublessor agrees that it will promptly forward Sublessee's request for such a
consent or approval to Landlord. If Sublessor is required or has determined to
give its consent or approval, Sublessor shall cooperate reasonably with
Sublessee in endeavoring to obtain Landlord's consent or approval (including
commencing and prosecuting an appropriate legal action if, in Sublessor's
judgment, Landlord wrongfully withholds or delays its approval or consent) upon
and subject to the following terms and conditions: (a) Sublessee shall
reimburse Sublessor for any reasonable out-of-pocket costs incurred by
Sublessor in connection with seeking such consent or approval, (b) Sublessor
shall not be required to make any payments to Landlord or to enter into any
agreements or to modify the Master Lease or this Sublease in order to obtain
any such consent or approval and (unless Sublessee reimburses Sublessor for
such payment or performs any other obligations imposed on Sublessor by
Landlord) and (c) if Sublessee agrees or is otherwise obligated to make any
payments to Sublessor or Landlord in connection with such request for such
consent or approval, Sublessee shall have made arrangements for such payments
which are satisfactory to Sublessor. Except as hereinafter expressly provided,
nothing contained in this Section shall be deemed to require Sublessor to give
any consent or approval because Landlord has given such consent or approval.
Whenever either party to this Sublease expressly agrees not to unreasonably
withhold its consent, such consent shall also not be unreasonably delayed or
conditioned.

                 18.02. Notwithstanding the foregoing provisions of this
Section or any other provision of this Sublease to the contrary, if and to the
extent that it is provided in the consent to this Sublease from Landlord or in
any other agreement entered into by and among Landlord, Sublessor and Sublessee
in connection with the approval by Landlord of this Sublease that Landlord and
Sublessee may deal directly in connection with the provision of various
services to be provided to the Demised Premises or for Sublessee to deal
directly with Landlord in connection with obtaining certain consents and
approvals then if and to the extent so provided in such consent and/or
agreement the granting of a consent or approval by Landlord shall be deemed to
be the granting of a like consent or approval by Sublessor.

                 19.  Sublessor's Inability to Perform.

                 19.01.  This Sublease and the obligation of Sublessee to pay
Rent hereunder and perform all of the other covenants and agreements

                                       22

<PAGE>

hereunder on the part of Sublessee to be performed shall in no way be affected,
impaired or excused because Sublessor is unable to fulfill any of its
obligations under this Sublease expressly or impliedly to be performed by
Sublessor or because Sublessor 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 any equipment or fixtures, if Sublessor is
prevented or delayed from so doing by reason of strikes or labor trouble or by
accident, adjustment of insurance or by any cause whatsoever reasonably beyond
Sublessor's control, including but not limited to, laws, governmental
preemption in connection with a national emergency or by reason of any rule,
order or regulation or any federal, state, county or municipal authority or any
department or subdivision thereof or any government agency or by reason of the
conditions of supply and demand which have been or are affected by war or other
emergency.

                 20.  Time Limits.

                 20.01. Except with respect to actions to be taken by Sublessee
for which time limits are specifically set forth in this Sublease, which time
limits shall control for the purposes of this Sublease, the time limits
provided in the Master Lease for the giving or making of any Notice (as
hereinafter defined) by the tenant thereunder to Landlord, the holder of any
leasehold mortgage or any other party, or for the performance of any act,
condition or covenant by the tenant thereunder, or for the exercise of any
right, remedy or option by the tenant thereunder, are changed for the purposes
of this Sublease, by shortening the same in each instance by five (5) days,
provided that in no event shall such time limit be reduced to less that two (2)
business days) so that any Notice may be given or made, or any act, condition
or covenant performed, or option hereunder exercised, by Sublessor within the
time limit relating thereto contained in the Master Lease.

                 20.02. Except with respect to actions to be taken by Sublessor
for which longer time limits are specifically set forth in this Sublease, which
time limits shall control for the purposes of this Sublease, the time limits
provided in the Master Lease for the giving or making of any Notice by Landlord
or the performance of any act, covenant or condition by Landlord for the
exercise of any right, remedy or option by Landlord thereunder are changed for
the purposes of this Sublease, by lengthening the same in each instance by five
(5) days, so that any Notice may be given or made, or any act, condition or
covenant performed or option hereunder exercised by Landlord within the number
of days respectively set forth above, after the time limits relating thereto
contained in the Master Lease.

                 21.  Limitations on Liability.

                 21.01. Nothing in this Section is intended to limit or affect
any obligations of Sublessor or any affiliate of Sublessor which are contained
in any separate agreement.

                 22.  Miscellaneous.

                 22.01. This Sublease shall be governed by and construed in
accordance with the internal laws of the State in which the Demised Premises
are located, without regard to the conflicts of law principles thereof.

                                       23

<PAGE>

                 22.02. The section headings in this Sublease and the table of
contents are inserted only as a matter of convenience for reference and are not
to be given any effect in construing this Sublease.

                 22.03. If any of the provisions of this Sublease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Sublease, or the application of
such provision or provisions to persons or circumstances other than those as to
whom or which it is held invalid or unenforceable, shall not be affected
thereby, and every provision of this Sublease shall be valid and enforceable to
the fullest extent permitted by law.

                 22.04. All of the terms and provisions of this Sublease shall
be binding upon and inure to the benefit of the parties hereto and, subject to
the provisions of Article 9 hereof, their respective successors and assigns.

                 22.05. Sublessor has made no representations, warranties or
covenants to or with Sublessee with respect to the subject matter of this
Sublease except as expressly provided herein or in the Transaction Documents
and all prior negotiations and agreements relating thereto are merged into this
Sublease. This Sublease may not be amended or terminated, in whole or in part,
nor may any of the provisions be waived, except by a written instrument
executed by the party against whom enforcement of such amendment, termination
or waiver is sought and unless the same is permitted under the terms and
provisions of the Master Lease.

                 23.  Rider.  A Rider to this Sublease is attached hereto and
incorporated herein by reference.

                                                   Salt Lake City, UT
                                    (Leased)


                                     RIDER

                 1. This Rider is a part of this Sublease. In the event of any
contradiction or inconsistency between the provisions of this Rider and the
provisions of the other portions of this Sublease, the provisions of this Rider
shall govern and prevail, and the contradicting and inconsistent provisions of
the other portions of this Sublease shall be deemed amended accordingly.

                 2. (a) The parties agree to endeavor in good faith to cause
the Landlord to execute, in substitution for the Master Lease, (i) a lease
directly with Unisys Corporation for Building B at the Property (the "Unisys
Lease") and (ii) a lease directly with Loral Corporation for Buildings E and F
at the Property (the "Loral Lease"), which leases shall be on terms and
conditions satisfactory to Sublessor and Sublessee, each in the exercise of its
reasonable discretion, provided, however, that Sublessor shall in no event be
required to execute any lease in substitution for the Master Lease unless
Landlord agrees to release Sublessor from all continued liability with respect
to Buildings E and F at the Property from and after the date of any such
substitute lease. Sublessor and Sublessee shall each pay one half of all
mutually agreed upon costs directly related to the substitution of the Loral
Lease and the Unisys Lease for the Master Lease.

                 (b) If the Landlord requires the Unisys Lease and the Loral
Lease to contain an obligation to purchase the Property in substitution for the
Purchase Obligation (as defined below) (a "Substitute Purchase Obligation"),
then (i) the Unisys Lease shall contain such Substitute Purchase Obligation
with respect to the introduction or release of a Hazardous Material on the
portion of the Property demised under the Unisys Lease, (ii) the Loral Lease
shall contain such Substitute Purchase Obligation with respect to the
introduction or release of a Hazardous Material on the portion of the Property
demised under the Loral Lease, and (iii) the Unisys Lease and the Loral Lease
shall provide that Sublessor and Sublessee shall share such Substitute Purchase
Obligation in proportion to their relative fault and shall acquire the Property
pursuant to such Substitute Purchase Obligation as tenants in common. Sublessor
shall be obligated to perform Sublessee's obligation under the Substitute
Purchase Obligation, as provided in this Section 2(b), in proportion to
Sublessor's fault in causing such obligation to arise. Sublessee shall be
obligated to perform Sublessor's obligation under the Substitute Purchase
Obligation, as provided in this Section 2(b), in proportion to Sublessee's
fault in causing such obligation to arise.

                 (c) Sublessor and Sublessee 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 premises demised under the
Unisys Lease from the premises demised under the Loral Lease. In the event that
the parties reach such a mutual agreement, then Sublessor shall perform such
agreed upon Alterations, and Sublessee shall, within thirty (30) days after
written demand by Sublessor, reimburse Sublessor for one-half of the costs and
expenses relating to such Alterations. Sublessor may request payment of
Sublessee's share of such costs, and (if requested) Sublessee shall pay its
share of such costs, as such costs are incurred by Sublessor

                                       26

during the course of design and construction of such Alterations. Sublessor
shall require that (i) any contractors or subcontractors performing any such
work maintain reasonable and appropriate liability insurance and (ii) any such
insurance policies shall name Sublessor, Sublessee and Landlord as additional
insureds.

                 (d) In the event that the Unisys Lease and the Loral Lease are
executed in substitution of the Master Lease, then this Sublease shall
terminate upon such execution.

                 3. The respective obligations of Sublessor and Sublessee in
respect of the obligation to purchase the Property pursuant to Section 13.2(d)
of the Master Lease (the "Purchase Obligation") shall be governed by the terms
of the Asset Purchase Agreement. In the event that Sublessor purchases the
Property pursuant to the Purchase Obligation, Sublessor and Sublessee shall
enter into a lease with respect to the Demised Premises on substantially the
same terms and conditions as set forth in this sublease.

                 4. Except as provided in the Asset Purchase Agreement,
Sublessee shall have no liability under this Sublease for Hazardous Materials
existing on the Demised Premises as of the date hereof.

                 5. Sublessee (together with its employees, licensees, and
invitees) shall have the exclusive right to use the 978 parking spaces at the
Property designated on Schedule B to this Sublease.

                 6. Sublessee hereby agrees to perform repairs and maintenance
on, and to provide such other services as may be required to the Demised
Premises, other than the services enumerated on Schedule E attached hereto,
during the Term hereof, which services were previously provided by Sublessor's
non-Defense Systems personnel. In connection therewith, Sublessor and Sublessee
shall share supplies and equipment located at the Property for performance of
their respective service obligations with respect to the Property until the
exhaustion of such supplies and equipment. Thereafter, Sublessor and Sublessee
shall separately purchase and use such supplies and equipment as each may
determine it requires for performance of its respective service obligations.

                 7. With respect to contracts entered into by Sublessor prior
to the date of this Sublease relating in whole or in part to the provision of
services to the Demised Premises, which services Sublessee has assumed the
obligation to provide as of the date of this Sublease and which services were
previously provided by Sublessor's non-Defense Systems personnel, (a) Sublessor
shall endeavor to terminate such contracts at the earliest possible time,
provided Sublessor shall not be obligated to breach such contracts and (b)
Sublessee shall be obligated to pay all sums due under such contracts for the
provision of goods and services to the Demised Premises.

                 8. From the date hereof until the earlier of (a) the
Expiration Date or (b) the service of written notice by Sublessor of its
election to terminate receipt of such services, Sublessee shall continue to
provide security services to the portions of the Property not part of the
Demised Premises, of the type generally and customarily provided by Sublessor's
Defense Systems unit to the Property prior to the date hereof.

Demised Premises for such month, provided that Sublessor's method of allocation
shall be consistent with the method of allocation used by Unisys Corporation to
allocate costs to the Unisys Defense Systems unit with respect to the occupancy
of the Demised Premises by the Unisys Defense Systems unit during calendar year
1994 and notwithstanding the fact that some portion of such costs are
disallowed as "contract pass-through items" under certain government contracts
performed by Sublessee at the Demised Premises. The foregoing costs and
expenses shall include cash items and non-cash items, such as depreciation. In
the event that Base Rent for any calendar quarter (as calculated above) shall
not be determinable by Sublessor until after the end of such calendar quarter,
then Base Rent shall be payable during such calendar quarter based upon
Sublessor's reasonable estimate of costs and expenses to be allocated to the
Demised Premises. Sublessor shall, as soon as practicable after the end of such
calendar quarter, provide Sublessee with a written statement of the Base Rent
amount for such calendar quarter and, subject to Section 3.5 of the Sublease,
the parties shall promptly thereafter make any necessary reconciliation
payments.

                        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

                                  THE CLOSING

                 2.1      Place and Date.  The closing of the sale and purchase
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
10166, or such other time and place upon which the parties may agree.  The day
on which the Closing actually occurs is herein sometimes referred to as the
"Closing Date."

                 2.2      Purchase Price.  On the terms and subject to the
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
in Section 2.7 (the "Purchase Price"), and to assume the Assumed Liabilities as
provided in Section 2.4.  The Purchase Price shall be paid by the wire transfer
of immediately available funds to such bank account or accounts as are

solely for this purpose the agreements contained in Section 5.1(f), in
accordance with Section 1060 of the Code as mutually agreed to by the parties
within 180 days following the Closing.  All such mutually agreed to allocations

prepared by independent firm(s) selected by Buyer and approved by Seller (such
approval not to be unreasonably withheld or delayed), and (b) used by each
party in preparing any filings required pursuant to Section 1060 of the Code or
any similar provisions of state or local law and all relevant income and
franchise tax returns, subject to adjustment to reflect the adjustment to the
Purchase Price provided for in Section 2.7.  Neither Buyer nor Seller will take
any position before any taxing authority or in any judicial proceeding that is
inconsistent with such mutually agreed to allocations without the prior consent
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.

                 2.4      Assumption of Liabilities.  Subject to the terms and
conditions set forth herein, at the Closing, Buyer shall assume and agree to
pay, honor and discharge when due only the following liabilities and

obligations of Seller under all retention incentive agreements as set forth in
Schedule


                                      -5-

2.4(a), but only to the extent that such payment obligations relate to the
failure of Buyer to hire employees of the STS Division or the involuntary
termination by Buyer without cause of the employment of any Transferred
Employee after the Closing; (b) all product warranty obligations of the
Business; (c) all liabilities and obligations of Seller to be performed from

                          (i)     the Excluded Assets;

                          (j)     all Environmental Liabilities and Costs

                                      -7-
<PAGE>

extent based on or arising out of or based upon product liability with respect
to products shipped or sold prior to the Closing; or

                          (n)     all intercompany obligations and liabilities

accounts payable reflected on the Final Closing Statement of Net Assets.

                 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
that requires the consent of a third party shall be made subject to such
consent or approval being obtained.  In the event any such consent or approval
is not obtained on or prior to the Closing Date, Seller shall (i) continue to
use all reasonable efforts to obtain any such approval or consent after the
Closing Date until such time as such consent or approval has been obtained
without any third party cost to Buyer, (ii) hold such Governmental Approval,
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,

including performance by Seller, as agent, and (iv) enforce and perform for the
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-
<PAGE>

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).

requisite corporate action of Seller.  Seller has duly executed and delivered

                          (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

Schedule 3.2(b).

                          (c)     Seller has delivered to Buyer complete and

performance by Seller of this Agreement and the consummation of the
transactions contemplated hereby, do not and will not conflict with or result
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
any party the right to terminate, modify or cancel under, or result in the loss

                 3.26     Mortgages.  If any parcel of Owned Real Property is
encumbered by one or more existing mortgages (each, an "Existing Mortgage"), no
written notice has been received from the mortgagee(s) asserting that a default
or breach exists thereunder or under any note or other obligation secured
thereby which remains uncured.  Seller knows of no default, or event which with
notice or the passage of time will constitute a default, under the Existing
Mortgage(s) or under any note or other obligation secured thereby which has
occurred and is continuing.  Seller has delivered to Buyer complete copies of
the documents constituting the Existing Mortgage(s) and the note(s) secured
thereby.

                          (f)     Noncompete.  Seller will not and will cause

trademarks, service names and service marks (collectively, "Names")
incorporating "California Microwave" or any similar Name and to all corporate
symbols or logos (collectively, "Logos") incorporating California Microwave or
any similar Name.  All rights of Seller and its respective affiliates to which

by Seller.  Buyer agrees that it will not, and will cause the Business not to,
use the Name California Microwave or any similar Name or any Logo incorporating
such Name or any similar Name in any manner, including in connection with the
sale of any products or services or otherwise in the conduct of its business,
except as expressly permitted by clause (ii) of this Section 5.2(d).

                                  (ii)     For a period of six months from the

surety bonds in substitution for the letters of credit and bonds referred to in
Schedule 5.2(e)


                                      -30-
<PAGE>

attached hereto and agrees to reimburse Seller for any out-of-pocket bank fees

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

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

programs based on the achievement of financial targets, on a basis comparable

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.

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

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

                 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),

expiration of the period of the applicable statute of limitations;


                                      -37-
<PAGE>

                           (ii)   any failure of Seller to perform any covenant
or agreement made or contained in this Agreement or fulfill any obligation in
respect thereof;

                          (iii)   any Excluded Liabilities;

                           (iv)   any and all Benefit Liabilities in respect of
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

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
Indemnifying Party, provided that if the Indemnified Party does so take over and
assume control, the Indemnified Party shall not settle such claim or litigation
without the written consent of the Indemnifying Party, such consent not to be
unreasonably withheld. In the event that the Indemnifying Party does not accept
the defense of any matter as above provided, the Indemnified 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
Indemnifying Party and the Indemnified Party shall cooperate in the defense of
any claim or litigation subject to this Article IX and the records of each shall
be available to the other with respect to such defense.

                 9.5      Expiration of Representations and Warranties, etc.
All representations and warranties contained in this Agreement shall survive
the Closing for a period of 18 months; provided that the representations and
warranties stated in Sections 3.6, 3.10(a), 3.18(a), 3.19 and 3.21 shall
survive the Closing for the applicable statute of limitations.

                 9.6      Exclusive Remedy.  The indemnifications provided for
in this Article IX shall be the sole and exclusive post-Closing remedies
available to either party against the other party for any claims under or based
upon this Agreement.

the jurisdiction of the courts of the State of New York, and the Federal courts
of the United States of America located in the Southern District of New York
solely in respect of the interpretation and enforcement of the provisions of
this Agreement and of the documents referred to in this Agreement, and hereby

provided in Section 8.2 with respect to indemnification of Indemnified Parties

                          (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.

      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.

      18. Export Control Compliance. Each party agrees to comply fully with the
United States Export Control Administration Regulations, the United States

United States government regulations applicable to the export or disclosure of
Products or Services provided hereunder or Confidential Information hereunder
insofar as they may control or limit the sale or use of Products or Services.
Each party also agrees to comply fully with the United States Foreign Corrupt
Practices Act.

      19. Force Majeure. Except for either party's payment obligations to the
other party for Products or Services previously delivered or provided hereunder,
failure of either party to perform its obligations under this Agreement
(including but not limited to failure to make sales or deliveries of Products or
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-
<PAGE>

governmental agency or failure of same to act where action is required, and the
inability of such party to obtain material from its suppliers or to obtain
equipment or transportation; and the time during which such party may perform
will be extended to coincide with the time performance has been prevented,
hindered or delayed as a result of the foregoing. Should either party wish to
claim relief from its obligations hereunder by reason of this Section, such
party shall give notice to the other party without delay of the occurrence of
the event or circumstances in question.

      20. Governing Law. This Agreement shall be governed in all respects,
including as to validity, interpretation and effect, by the internal laws of the
State of New York, without giving effect to the conflict of laws rules thereof.
The parties hereby agree that this Agreement shall not be governed by the United
Nations Convention on Contracts for the International Sale of Goods.

      21. Assignment. The Agreement shall not be assignable or otherwise
transferable by either party hereto without the prior written consent of the
other party, which consent will not be unreasonably withheld. This Agreement

the parties hereto. References to a party herein also are deemed to be
references to any successor or permitted assign of such party.

delivered to Buyer a statement of estimated Acquired Assets and Assumed
Liabilities (the "Estimated Closing Statement of Net Assets") as of the date

to Section II.3(c), except that it shall be unaudited. The term "Estimated
Closing Date Net Assets" shall mean the book value of the Acquired Assets set

"Closing Date Net Assets" as used herein shall mean the book value of the
Acquired Assets set forth on the Final Closing Statement of Net Assets (as
hereinafter defined) in excess of the amount of the Assumed Liabilities set

increase to the Cash Purchase Price pursuant to this Section II.3(b) plus
interest from the Closing Date at the Prime Rate (as hereinafter defined) shall
be paid by the 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 agreed to on behalf of the Seller and Buyer or
is determined by the Neutral Auditor (as hereinafter defined). For purposes of
this Agreement, "Prime Rate" means the rate of interest announced from time to

      (c) Preparation of Closing Statement of Net Assets. As soon as

consummated the transactions contemplated thereby on such date (the "Closing
Statement of Net Assets"). The Closing Statement of Net Assets will be prepared
in accordance with United States generally accepted accounting principles
("GAAP") applied on a basis consistent with the September Balance Sheet through
full application of the policies and procedures used in preparing the September
Balance Sheet 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 Balance Sheet, and will, at the
option of the Buyer, be audited by an independent public accounting firm
selected by Buyer (the "Auditor"). The Closing Statement of the Net Assets shall
be accompanied by an Auditor's report based upon the audit of the Audited
Closing Statement of Net Assets stating that such statement presents fairly, in
all material respects, the Acquired Assets and Assumed Liabilities presented on
such statement as provided for in this Agreement at the third Business Day prior
to the Closing Date in conformity with GAAP consistently applied with the
September Balance Sheet, except as modified by any modification which is
mutually agreed upon by the parties hereto. Buyer shall provide the Auditor
access to the Books and Records as may reasonably be required for the
preparation of the Closing Statement of Net Assets. Buyer shall be responsible
for the costs and expenses of the Auditor in preparing the Closing Statement of
Net Assets.

      II.4 Post-Closing Payment.

      (a) As additional consideration for the Acquired Assets ("Additional
Consideration"), Buyer shall make the payments or deliveries to the Seller
required pursuant to this Section II.4. With respect to each of fiscal years of
the Acquired Company ending December 31, 1998, 1999 and 2000, respectively.
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
"Percentage") calculated by dividing (x) EBIT (as defined below) for the
Acquired Company for each in each of fiscal 1998, 1999 and 2000 by (y)
$8,800,000 for 1998, $10,300,000 for 1999 and $12,300,000 for 2000, respectively
provided that the maximum Percentage for any fiscal year shall be 120%.


                                       -8-
<PAGE>

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
of tangible or intangible assets of the Business resulting from a write-up of
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
authorization of the United States Securities & Exchange Commission or any state
securities administrator, (II) providing any advance notice to any such body or
(III) taking other action to remove any legend or legend condition applicable to
such shares of Class A Common Stock that would delay the sale thereof and (b) is
not subject to any material delay in attempting the sale thereof on a public
securities exchange due to any attribute of the Class A Common Stock.

      (e) At any time and from time to time, the Seller shall have the right, by
written notice (an "Early Cash Payment Election") to Buyer, to elect to require
Buyer to pay to the Seller the cash amount of any Additional Consideration
payable to the Seller pursuant to Section II.4(c), with the date of payment
being determined pursuant to the first sentence of such Section without regard
to the proviso thereto.

      (f) Upon a Change of Control (as hereinafter defined) that occurs prior to
the earlier to occur of the dates referred to in clauses (i) and (ii) of the
proviso to the first sentence of Section II.4(c), the Seller shall receive in
connection with such Change of Control all Additional Consideration payable to
the Seller pursuant to Section II.4(c) but not then paid by reason of the


                                      -10-
<PAGE>

proviso contained in the first sentence of such Section prior to the date of
such Change of Control the amount and kind of consideration the Seller would
have received in respect of the shares of Class A Common Stock which the Seller
would have been entitled to elect to receive pursuant to subsection (d) of this
Section II.4 if there had been an Initial Public Offering immediately prior to
the date of the Change of Control. Such amount shall be payable at such time as
the holders of Class A Common Stock receive consideration in connection with
such Change of Control. In the event of a Change of Control, notwithstanding
anything to the contrary contained herein, any Additional Consideration which
becomes payable pursuant to Section II.4(c) following the date of such Change of
Control shall be payable in cash.

      For purposes of this Section II.4(f), "Change of Control" shall mean (i)
an acquisition by any person (other than stockholders of Holdings as of the
Closing Date or any of their affiliates) of more than 50% of the combined voting
power of the outstanding voting securities entitled to vote generally of
Holdings or (ii) the sale of substantially all of the direct or indirect assets
of Holdings to any person (other than stockholders of Holdings as of the Closing
Date or any of their affiliates).

      (g) The rights of the Seller under this Section II.4 shall be assignable
(in whole or in part) by Seller, subject to the following requirements: (i) any
such assignment shall be made prior to the date six months following the Closing
Date; (ii) if such assignment is to more than one person or entity, (1) any
payment or delivery pursuant to this Section II.4 shall be pro rata, based on
the relative percentage of Additional Consideration to which such person or
entity is entitled hereunder, (2) the $250,000 limitation contained in Section
II.4(c) shall apply to each such person or entity and (3) adequate provision
shall be made in connection with such assignment so that one assignee in
connection with any disputes concerning the calculation and determination of any
amounts payable pursuant to this Section II shall be authorized to resolve any
and all disputes with the Buyer on behalf of all assignees; and (iii)
notwithstanding any such assignment, the right of offset against Seller referred
to in the last sentence of Section VI.2(a) shall continue to apply
notwithstanding such assignment (i.e., a claim against the Seller under Section
VI.2 may be satisfied by exercising such right of offset against amounts due to
an assignee of Seller).

      II.5 Dispute Resolution.

      (a) Review of Closing Statement of Net Assets and EBIT Report. After
receipt of the Closing Statement of Net Assets or the EBIT Report, Buyer or the
Seller, as the case may be, shall have thirty (30) days to review it. Buyer or
the Seller, as applicable, and their respective authorized representatives shall
have full access to all Books and Records and employees of the Company and, with
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


                                      -11-
<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).

Subsidiary and, to the Knowledge of the Seller, the other parties thereto
enforceable in accordance with its terms against the parties thereto. No consent

                   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

      (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.

Agreement is executed and delivered on behalf of Seller by First Union National

                                                            EXHIBIT VIII-2

                              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

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

                  (g) prepaid expenses, except insurance premiums, but only
if and to the extent of the benefit conferred by such prepaid expenses to the
Business after the Closing Date;

                  (h) all transferable rights of Sellers pursuant to any
express or implied warranties, representations or guarantees relating to any
Personal Property or made by suppliers furnishing goods or services to Sellers;

                  (i) all lists, files and documents, including, but not

<PAGE>




                  (l) all goodwill and going concern value (without any
representation as to any value thereof);

                  (m) all claims, causes of action, choses in action, rights of

those related to Excluded Assets or Excluded Liabilities);

                  (n) all insurance proceeds arising out of or related to
damage, destruction or loss of any property or asset of or used primarily in
connection with the Business to the extent of any damage or destruction that
remains unrepaired, or to the extent any property or asset remains unreplaced,
at the Closing Date; and

                  (o) all the issued and outstanding capital stock and rights
in respect of such capital stock of ELAC (the "ELAC Shares").

         1.2 Non-Assignable Assets. Notwithstanding anything to the contrary
contained in this Agreement, to the extent the sale, assignment, transfer,
conveyance or delivery to Purchaser of any Asset, or any other item to be
delivered at Closing, such as a permit, license or consent, is prohibited by
any foreign, federal, state or local statutes, laws or regulations applicable
to the Assets or the operation of the Business (an "Applicable Law") or would
require any governmental or third party authorizations, approvals, consents or
waivers which shall not have been obtained prior to the Closing (after Sellers'
reasonable best efforts to obtain them), this Agreement shall not constitute a
sale, assignment, transfer, conveyance or delivery thereof. Following the
Closing, the parties shall use reasonable best efforts and cooperate with each
other to obtain promptly such authorizations, approvals, consents or waivers;
provided, however, that neither Sellers nor Purchaser shall be required to pay
any consideration therefor, other than filing, recordation or similar fees
payable to any governmental authority, which fees shall be paid in accordance
with Section 2.6. Pending such authorization, approval, consent or waiver, the
parties shall cooperate with each other in any commercially reasonable and
lawful arrangements designed to provide to Purchaser the benefits of use of
such Asset. Once such authorization, approval, consent or waiver is obtained,
the Sellers shall promptly assign, transfer, convey and deliver such Asset to
Purchaser for no additional consideration. To the extent that any such Asset
cannot be transferred or the full benefits of use of any such Asset cannot be
provided to Purchaser following the Closing, then Purchaser and Sellers shall
enter into such arrangements for no additional consideration from Purchaser
(including subleasing or subcontracting if permitted) to provide Purchaser the
economic (taking into account tax costs and benefits) and operational
equivalent of obtaining such authorization, approval, consent or waiver.

         1.3  Excluded Assets.  Notwithstanding anything to the contrary
contained in this Agreement, the following are not included in the Assets and
not intended to be sold, assigned, transferred or conveyed to Purchaser
hereunder (the "Excluded Assets"):

              (a) assets primarily related to, or used primarily in
connection with, Sellers' businesses other than the Business, including, but
not limited to, the assets primarily related to, or used primarily in
connection with, Sellers' avionics repair and overhaul business conducted at
the Facility;

                                       3

                      equivalents and overdrafts;

                  (c) intercompany receivables and intercompany prepaid

                  (d) Books and Records which Sellers are required by law to
retain; provided, however, that in the event of such legal requirement, Sellers
shall retain copies of such Books and Records and deliver the original Books
and Records to Purchaser unless Sellers are legally obligated to retain the
original records in which case the copies of such Books and Records shall be
provided to Purchaser;

                  (e) the basic books and records of account and all supporting
vouchers, invoices and other records and materials relating to any or all
income taxes of Sellers; other than all such materials relating solely to the
Business and located at the Facility or at ELAC's headquarters in Kiel, Germany
(the "ELAC Facility");

                  (f) except as granted pursuant to Section 1.1(d) any right to
use any name or logo of Sellers or any Affiliate or any confusingly similar
variant or derivative thereof, including but not limited to "Allied-Signal",
"AlliedSignal", "Allied", "Allied Chemical," "Signal," "Bendix," "Bendix
Oceanics" or "Bendix Oceanics, Inc.";

                  (g) the insurance policies of Sellers, including without
limitation those pertaining to the Business and the Facility, and the rights
of Sellers thereunder;

                  (h) the Intellectual Property listed in Schedule 4.6 (c)
(the "Licensed Property");

                  (i) assets of employee benefit plans, except as provided
in Article 6;

                  (j) the assets listed in Schedule 1.3(j); and

                  (k) the Facility.

         1.4 Transfer of the Assets. Sellers shall sell, convey, transfer,
assign and deliver the Assets to Purchaser at the Closing by means of deeds,
bills of sale, assignments, endorsements, consents, certificates and such other
good and sufficient instruments of transfer in form and substance reasonably
satisfactory to Purchaser, and all in recordable form, where applicable, as
shall be necessary or appropriate to vest in Purchaser all right, title,
ownership and interest of Sellers in and to the Assets as provided in this
Agreement or in the Schedules hereto.

         1.5 Sale and Transfer of ELAC Shares. Sellers shall cause to be
delivered to the Purchaser certificates representing the ELAC Shares, duly
endorsed, or accompanied by stock powers duly executed, with all necessary
stock transfer stamps attached thereto and cancelled,

<PAGE>



or such other assignments, deeds, share transfer forms, endorsements, notarial
deeds of transfer or other instruments or documents, duly stamped where
necessary.

         1.6 License Agreement. On or prior to the Closing Date, ASTI and
Purchaser shall enter into a license agreement in the form attached hereto as
Exhibit A, with respect to the intellectual property identified in Schedule
4.6(c).


                       ARTICLE 2. CLOSING; PURCHASE PRICE

         2.1 Closing Date and Place. On and subject to the conditions set forth
herein, the consummation of the purchase and sale contemplated hereby (the
"Closing") will take place at the offices of AlliedSignal in Morristown, NJ at
10:00 a.m., local time, on March 30, 1998, or at such other time and place as
shall be agreed upon by the parties hereto. The date upon which the Closing
occurs is referred to herein as the "Closing Date". The Closing shall be
effective as of 11:59 p.m. on the Closing Date. In addition, subsequent to the
Closing, Purchaser and Sellers shall call the notary in Europe in order to
perfect the transfer of the ELAC Shares by way of a notarial deed.

         2.2      Purchase Price.  (a)  The purchase price to be paid by
Purchaser for the Assets including the ELAC Shares, is Sixty-Seven Million
Five Hundred Thousand Dollars ($67,500,000) (the "Purchase Price").  The
Purchase Price shall be paid by Purchaser in full at Closing in immediately
available funds.

                  (b) The parties acknowledge the existence of a receivable
relating to a contract dated December 19, 1997 (the "Turkey Contract") pursuant
to which Ocean Systems is to supply to the Turkish Navy four (4) AQS-18A
dipping sonar systems, plus spares, ground support equipment and performance
testing (the "Turkey Receivable"). In the event that any cash is received by
AlliedSignal in respect of the Turkey Receivable, whether before, on or after
the Closing Date (each a "Turkey Cash Receipt"), AlliedSignal shall pay to L-3
an amount in cash equal to all Turkey Cash Receipts, on April 1, 1998, or if
any Turkey Cash Receipt is received by AlliedSignal after April 1, 1998, on the
date of such receipt.

         2.3 Income Taxes. As soon as reasonably practicable, the parties shall
prepare a calculation of income tax liability or tax benefit based on the
income or loss reflected on the books and records of the Business determined on
a basis consistent with prior periods (excluding any income or loss
attributable to the Turkey Contract) for the period beginning after December
31, 1997 (the "Effective Date") and ending on the close of the Closing Date
multiplied by 36.6%. The calculation of book income or loss for such period
shall be computed by means of a closing of the books and records of the
Business as of the Closing Date, and, to the extent not practical, by
apportionment on the basis of elapsed days. Buyer shall pay to Seller any such
income tax liability and Seller shall pay to Buyer any such income tax benefit
within 60 days thereof.

         2.4      Cash True-Up.  Within fifteen business days after the
Closing Date, AlliedSignal shall prepare and deliver to Purchaser a schedule
setting forth, on a daily basis, the cash generated by the Business from
12:01 a.m. on the first day following the Effective

                                       5

<PAGE>



Date through and including the Closing Date. Purchaser shall have three
business days from receipt to review the schedule and AlliedSignal shall give
Purchaser reasonable access to its books and records for the purpose of
confirming the calculations of AlliedSignal pursuant to this Section 2.4. Any
dispute with respect to the schedule shall be resolved in good faith by the
parties. Within three business days after the expiration of such review period
(or the resolution of any dispute), Purchaser shall make payment to
AlliedSignal if the schedule shows a net cash usage by the Business during such
period and AlliedSignal shall make payment to Purchaser if the schedule shows
net cash generation during such period in an amount equal to such net cash
usage or net cash generation, as the case may be; provided, however, that if
AlliedSignal shall pay to Purchaser any amount pursuant to Section 2.2(b) in
respect of a Turkey Cash Receipt received on or prior to the Closing Date, and
the amount of such Turkey Cash Receipt would have been a cash generation under
this Section 2.4 but for this proviso, then the amount of any such Turkey Cash
Receipt shall be excluded in calculating net cash generation or a cash usage
under this Section 2.4. Any payment to be made pursuant to this Section 2.4
shall be made in immediately available funds by wire transfer to a bank account
designated in writing by the party entitled to receive the payment.
AlliedSignal shall be responsible for paying any checks outstanding as of the
Effective Date.

         2.5 Allocation of Purchase Price. The Sellers and the Purchaser agree
to allocate the Purchase Price of the Assets including the covenant not to
compete, in accordance with the rules under Section 1060 of the Internal
Revenue Code of 1986, as amended (the "Code") and the Treasury Regulations
promulgated thereunder. Such allocation shall be mutually agreed between the
Sellers and the Purchaser. The Sellers and the Purchaser recognize that the
Purchase Price does not include Purchaser's acquisition expenses and that
Purchaser will allocate such expenses appropriately. Sellers and the Purchaser
agree to act in accordance with the computations and allocations as determined
pursuant to this Section 2.5 (including any modifications thereto reflecting
any post-Closing adjustments, such adjustments shall be allocated in accordance
with the character of each such adjustment, on a basis consistent with the
allocation under this Section 2.5) in any relevant Tax Returns or filings,
including any forms or reports required to be filed pursuant to Section 1060 of
the Code, the Treasury Regulations promulgated thereunder or any provisions of
local, state and foreign law ("1060 Forms"), and to cooperate in the
preparation of any 1060 Forms and to file such 1060 Forms in the manner
required by Applicable Law.

         2.6 Payments. All payments required to be made pursuant to this
Article 2 and other provisions of this Agreement shall be made in United States
dollars in immediately available funds by wire transfer to an account
designated by the party to receive payment in writing to the party making
payment.

         2.7 Transfer Taxes. Purchaser and Sellers shall each bear 50% of all
sales, transfer and similar taxes, duties or levies (other than taxes computed
on the basis of income) assessed or payable in connection with the transfer of
the Assets including the ELAC Shares to Purchaser, including notary fees
relating to the transfer of the ELAC Shares; provided that in no event shall
Sellers be required to pay more than $500,000 in respect thereof, including any
amounts paid by AlliedSignal pursuant to Section 2.4 of the real estate
purchase agreement, dated as of December 22, 1997 (the "Facility Sale
Agreement"), between AlliedSignal and Purchaser. Purchaser and Sellers agree to
cooperate with one another to try

                                       6

<PAGE>



to minimize such taxes to the extent practicable without additional costs or
liabilities to Purchaser or Sellers. To the extent any exemptions from such
taxes are available, Purchaser and Sellers shall cooperate to obtain and
prepare all required resale or other exemption certificates with respect to the
Assets and the ELAC Shares.


              ARTICLE 3. ASSUMPTION OF LIABILITIES AND OBLIGATIONS

         3.1 Assumed Liabilities. Except for the Excluded Liabilities,
Purchaser shall, without any further responsibility or liability of, or
recourse to, Sellers, except as set forth herein, absolutely and irrevocably
assume and be solely liable and responsible for any and all liabilities and
obligations of any kind or nature, whether foreseen or unforeseen, known or
unknown, existing or which may arise in the future, fixed or contingent,
matured or unmatured, to the extent primarily related to the Business or the
Assets prior to, on, or following the Closing Date (the "Assumed Liabilities")
including, but not limited to:

                  (a)  obligations to fill purchase orders of customers
of the Business to the extent such orders are unfilled on the Closing Date;

                  (b)  obligations incurred through the Closing Date to
purchase or pay for goods and services for the Business to be received on or
after the Closing Date;

                  (c) obligations and liabilities under the Contracts; provided
that any Contract as to which consent to assignment is required but has not
been obtained shall not be deemed an Assumed Liability until Purchaser has
obtained the benefits of such Contract;

                  (d) obligations and liabilities under licenses and permits of
the Business that are transferred or assigned to Purchaser (but only to the
extent so transferred or to the extent Purchaser receives the benefits
thereunder pursuant to Section 1.2); and

                  (e) obligations and liabilities specifically assumed or
undertaken by Purchaser hereunder.

         3.2      Excluded Liabilities.  Notwithstanding anything to the
contrary contained in this Agreement, the liabilities and obligations of
Sellers which are not to be assumed or retained by Purchaser hereunder (the
"Excluded Liabilities") include, but are not limited to, the following:

                  (a) obligations and liabilities for all Taxes relating to
the Business for all periods prior to the Effective Date;

                  (b) obligations and liabilities arising out of or related to
past, present or future actions, suits, claims, disputes, investigations and

                                       7

<PAGE>



                  (c) obligations and liabilities related to employees,
including former employees, not expressly assumed by Purchaser pursuant to
Article 6 hereof;

most recent schedule delivered to the U.S. Government or any non-U.S.
Government which identifies by description or inventory number certain
equipment and fixtures loaned, bailed or otherwise furnished to or held by the
Business by or on behalf of the United States or any foreign country. To the
Knowledge of Sellers, such schedule was accurate and complete on its date and,
if dated as of the Closing Date, would contain only those additions and omit
only those deletions of equipment and fixtures that have occurred in the
ordinary course of business, except for such inaccuracies that could not

current certificate of occupation or similar permit, the sale of the Assets

                  (d) All improvements on the Real Property constructed by or
on behalf of Sellers or any other person were at the time installed constructed

to the ownership or operation of all improvements on the Real Property, other

each parcel of Real Property, and there is not under any lease of any of the
leased Real Property (a "Lease") any default by any of Sellers or ELAC
thereunder or any condition that with notice or the passage of time or both
would constitute such a default, and Sellers and ELAC have not received notice
asserting the existence of any such default or condition. To the Knowledge of
Sellers there are no defaults under any Lease by the landlord thereunder.
Sellers have heretofore furnished the Purchaser a true and complete copy of
each Lease and all amendments thereto pertaining to any leased Real Property.
Each Lease is valid and binding and in full force and effect;

                  (g) The rental set forth in each Lease is the actual rental
being paid, and there are not separate agreements or understandings with
respect to the same; and

                  (h) Neither the execution of this Agreement nor the sale of
the Assets hereunder shall cause a default under any Lease or require prior
written consent of any landlord under any Lease.

and ELAC with respect to the Assets and the ELAC Assets and with respect to the

AGREEMENT, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO THAT
ALLIEDSIGNAL IS MAKING NO REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR
IMPLIED, BEYOND THOSE EXPRESSLY GIVEN IN THIS AGREEMENT, INCLUDING BUT NOT
LIMITED TO ANY IMPLIED WARRANTY OR REPRESENTATION AS TO CONDITION,

carry out this Agreement have been, or prior to the Closing will be, duly and
properly taken. This Agreement has been, and on the Closing Date each of the

         5.3 Compliance. The execution, delivery and performance of this

the articles of incorporation, by-laws or other organization documents of
Purchaser or any material agreement, lease, mortgage, note, deed of trust,
lease, bond, indenture, license or other document or undertaking, oral or
written, to which Purchaser is a party or by which Purchaser is bound or by
which any of the Assets may be affected other than the consent required under

prior to Closing.


                                       21

         5.4 Due Diligence. Purchaser has such knowledge and experience in
financial and business matters that it is capable of evaluating the merits and
risks of the transactions contemplated by this Agreement and the Other
Agreements. Purchaser confirms that AlliedSignal provided to Purchaser the

AlliedSignal and to acquire such additional information about the business and
financial condition of the Business as Purchaser requested and all such
information has been received.

         5.5 Financing. Purchaser has funds of its own, or has binding

state fraudulent conveyance or similar statute in a state in which the Business
or Purchaser is doing business.

a period of at least 12 months immediately subsequent to the Closing Date, for
all Transferred Employees who are employed in the United States (collectively,
"U.S. Transferred Employees") base salary or applicable rate of pay not less
than that provided by Sellers immediately prior to the Closing Date, employee
benefits and incentive compensation comparable, in the aggregate, to those in
effect as of the Closing Date, except that, with respect to those plans
providing a benefit in AlliedSignal stock, Purchaser shall have no obligation
to provide such benefits or comparable benefits or to take into account such
benefits for purposes of this Section. Purchaser shall assume liability for all
deferred compensation, supplemental and excess pension and savings benefits,
all bonus amounts, normal and enhanced severance benefits, and relocation
benefits (whether or not all such employee benefits are vested on the Closing
Date) in respect of all U.S. Transferred Employees incurred or earned, but not
paid, on or before the Closing Date, or as incurred in connection with the sale
of the Business and not paid as of the Closing Date, to the extent accrued on
the Closing Balance Sheet. Purchaser shall assume the retention agreements
listed on Schedule 6.2(a).

                  (b) Union Employees. Purchaser shall offer employment on or
prior to the Closing Date to each U.S. Employee covered by the Collective
Bargaining Agreements between AlliedSignal and the United Auto Workers ("UAW")
or UAW Local 179, including the Local Agreement between AlliedSignal and UAW
Local 179, the Master Agreement between AlliedSignal and the UAW, and all
associated agreements that are part of such Master Agreement, including the

savings plans (collectively, the "Bargaining Agreements") as described in
Schedule 4.7 (such covered Employees being referred to, collectively, as "Union
Employees"), provided that such Union Employee is actively at work on the
Closing Date. Purchaser shall provide each Union Employee with compensation
(base rate of pay and incentive compensation, if any) no less than that
required by the applicable Bargaining Agreements and any applicable side
letters and schedules immediately prior to the Closing Date. A Union Employee
who is absent on the Closing Date due to illness, vacation, paid leave, holiday
or union office leave or who is otherwise subject to recall with seniority
rights shall to the extent required by the applicable Bargaining Agreement and
any applicable side letters and schedules be considered actively at work on the
Closing Date. The Union Employees who are actively at work on the Closing Date
shall hereafter be called "Union Transferred Employees". Sellers shall retain
the obligation to provide any Union Employee who does not become a Union
Transferred Employee on the Closing Date with benefits under Sellers' Pension
Plans for Union Employees, as defined herein, and all other benefits required
to be provided by the Bargaining Agreements.

                  (c) Purchaser agrees to credit each U.S. Transferred Employee
service credited with Sellers under the Benefit Plans for participation,
retirement eligibility and vesting under such employee benefit plans or
policies Purchaser maintains or will maintain for or on behalf of the U.S.

purposes under welfare plans (including severance plans), vacation plans and
qualified retirement plans in respect of which assets and liabilities are

Purchaser's Plans.  Sellers shall not in any manner be responsible for any

         6.3 Severance and WARN Act. (a) Sellers shall pay and be responsible
for all liability, cost or expense for severance, termination indemnity
payments, salary continuation, special bonuses and like costs under Sellers'
severance pay plans, policies or arrangements, with respect to any of the
Employees that arise from or relate to the transactions described in or
contemplated by this Agreement, or of any U.S. Transferred Employees that arise
under Sellers' severance plans from the subsequent termination of employment by
Purchaser after the Closing Date. Purchaser agrees to pay and be responsible
for all liability, cost, expense and sanctions resulting from the Purchaser's
failure to comply after the Closing Date with the Worker Adjustment and
Retraining Notification Act of 1988 ("WARN Act"), and the regulations
thereunder or for any action by Purchaser which causes WARN to apply.

                  (b) The Sellers shall not, at any time within the 60-day
period prior to the Closing Date, effectuate a "plant closing" or "mass
layoff", as those terms are defined in the WARN Act or any State law, affecting
in whole or in part any Ocean Systems site of employment, facility, operating
unit or employee.

                  (c) The Sellers shall indemnify, defend and hold Purchaser
harmless from and against any and all claims, actions, suits, demands,
proceedings, losses, expenses, damages, obligations and liabilities (including
costs of collection, attorney's fees and other costs of defense) ("Damages")
arising out of or otherwise in respect of (i) termination by the Sellers of any
employee of the Business on or prior to the Closing Date; (ii) any claim made
by any employee of the Business for severance pay arising prior to, or upon the
Closing Date; or (iii) any suit or claim of violation brought against the
Purchaser under the WARN Act or any State law for any actions taken by the
Sellers in connection with, on or prior to the Closing Date with regard to any
site of employment, facility, operating unit or employee affected by this
Agreement which action by itself causes WARN to apply.

         6.4 Health Care Continuation Liability. With respect to Sellers'
plans, Seller agrees to pay and be responsible for all liability, cost,
expense, taxes and sanctions under Section 4980B of the Internal Revenue Code
(the "Code"), interest and penalties imposed upon, incurred by, or assessed
against Purchaser or Sellers that arise by reason of or relate to any failure
to comply with the health care continuation coverage requirements of Section
4980B of the Code and Sections 601 through 608 of ERISA, as amended, which
failure occurs as a result of the transactions described in or contemplated by
this Agreement or which failure occurs on or after the Closing Date with
respect to any Employee or any qualified beneficiary (as defined in Section
4980B(g)(1)) of such Employee.

         6.5      Pension Plan.

                  (a) AlliedSignal shall amend the Salaried Employees Pension
Program for AlliedSignal Inc., the AlliedSignal Inc. Pension Plan for Hourly
Employees (provisions relating to UAW Local 179) and the AlliedSignal Inc.
Retirement Program (collectively, the "Pension Plans") to fully vest all
Employees employed by the Business as of the Closing Date participating in the
Pension Plan in their accrued benefit as of the Closing Date. Purchaser

                                       24

<PAGE>



shall assume the liabilities and obligations as of the Closing Date of Sellers
for the accrued benefits of all U.S. Transferred Employees under the Pension
Plans. Purchaser shall have established as of the Closing Date, or shall
establish as soon as practicable after the Closing Date, a tax-qualified
defined benefit pension plan or plans which shall discharge the pension
obligations of Purchaser set forth in this Section ("Purchaser's Plan"). As
soon as practicable after the Closing Date, AlliedSignal shall cause a transfer
of the pension liabilities and obligations being assumed by Purchaser and of
the assets, as calculated below, to Purchaser's Plan.

                  (b) The assets to be transferred from the Pension Plans to
Purchaser's Plan shall be an amount equal to the "projected benefit
obligation," within the meaning of Financial Accounting Standard No. 87, as of
the Closing Date attributable to the U.S. Transferred Employees under Sellers'
Pension Plans ("PBO") with adjustments described below. Sellers' actuary shall
calculate the transfer amount (the "Transfer Amount") by applying the
assumptions, methods and methodologies listed on Schedule 6.5(b) and other
actuarial assumptions and methodologies used in the ordinary course in the
preparation of the actuarial valuation not inconsistent with those listed in
Schedule 6.5(b). Notwithstanding any provision herein to the contrary, the
transfer amount shall be subject to the applicable requirements of Sections
414(l) and 401(a)(12) of the Code. The amount as so determined shall be
adjusted for investment earnings at the short term investment fund rate earned
by Sellers' Pension Plans (the "Earnings") for the period between the Closing
Date and the actual dates of transfer (see below) and reduced by the amount of
any benefit payments to U.S. Transferred Employees and a proportional share of
investment and administrative expenses relative to asset values for such
period. The amount of assets caused to be transferred pursuant to this Section
shall be calculated by Sellers' actuary, and the actuarial calculations shall
be subject to review and approval by Purchaser's actuary. In the event that
Purchaser's actuary does not agree with the calculation determined by Sellers'
actuary, the determination of the amount to be transferred pursuant to this
Section shall be made by a third, nationally recognized actuarial firm selected
by Sellers' and Purchaser's actuaries (the cost of which shall be borne equally
between Sellers and Purchaser), and the determination of such third actuary as
to the amount to be transferred shall be binding and conclusive upon all
parties hereto. The transfer of assets from Sellers' Pension Plan to
Purchaser's Plan shall be made in cash pursuant to Section 6.5(c). The parties
shall file any necessary IRS Forms 5310-A with respect to such transfer.

                  (c) All transfers from the Pension Plans to the Purchaser's
Plan shall be made in accordance with the provisions of this Section 6.5(c). As
soon as is administratively practical, but in no event later than 30 days
following the Closing Date, and conditioned upon AlliedSignal having been
provided evidence reasonably satisfactory to it that Purchaser has established
a trust (or trusts) to hold the assets of the Purchaser's Plan and that
Purchaser's Plan is qualified under Section 401(a) of the Code and the trusts
holding assets of the Purchaser's Plan are tax exempt under Section 501(a) of
the Code ("Initial Transfer Date"), AlliedSignal shall cause its trusts to make
an initial transfer of assets in cash equal to 85% of the amount reasonably
estimated by AlliedSignal in good faith to be equal to the Transfer Amount (the
"Initial Transfer Amount"). In addition, prior to the Initial Transfer Date
AlliedSignal shall provide Purchaser with evidence reasonably satisfactory to
Purchaser that the Pension Plans remain qualified under Section 401(a) of the
Code. As soon as practicable

                                       25

after the final determination of the amounts to be transferred ("True-Up
Date"), AlliedSignal shall cause a second transfer to be made in cash of the
"True-Up Amount." The True-Up Amount shall be equal to the following amount:

         (Transfer Amount minus Initial Transfer Amount), minus benefit
         payments made to U.S. Transferred Employees since the Closing Date
         from the Pension Plans, adjusted for Earnings on the excess of the
         Transfer Amount over the Initial Transfer Amount from the Initial
         Transfer Date to the True-Up Date,

If the Initial Transfer Amount exceeds the Transfer Amount, as soon as
practicable following such determination Purchaser shall cause a transfer to be
made to the respective Pension Plan equal to the excess of the Initial Transfer
Amount over the Transfer Amount, adjusted to reflect earnings at the short term
investment fund rate earned by Purchaser's Plan from the Initial Transfer Date
until the date of transfer.

         6.6 Savings Plan. AlliedSignal shall provide that those Employees
participating in the AlliedSignal Savings Plan and AlliedSignal Thrift Plan
("Savings Plans") immediately prior to the Closing Date shall fully vest on the
Closing Date in their respective Savings Plans accounts (the "Accounts"). As
promptly as practicable following the Closing Date, Sellers and Purchaser shall
arrange for the transfer of the Accounts and the corresponding liabilities with
respect to the U.S. Transferred Employees, from the Savings Plans to one or
more tax-qualified plans established or to be established by Purchaser which
provides benefits substantially equivalent to the benefits available under the
applicable Savings Plans. With respect to the plan or plans receiving assets
from the Savings Plans, to the extent permitted by Applicable Law, such plan or
plans shall also (a) provide for tax-deferred contributions and (b) meet all
requirements for a qualified cash or deferred arrangement under Section 401(k)
of the Code. The transfer of assets from the Savings Plans shall be made in
cash, marketable securities, promissory notes presenting participant loans, or
a combination thereof, as determined by AlliedSignal and consented to by
Purchaser. Without limiting the generality of the foregoing, if AlliedSignal
should determine to transfer assets held in Accounts which, immediately prior
to the Closing Date, provide for holding AlliedSignal common stock in such
form, Purchaser agrees to accept transfer of such Accounts in AlliedSignal's
common stock, and, to the extent permitted by law for such reasonable period of
time as Purchaser may determine, to provide U.S. Transferred Employees with an
election to retain AlliedSignal's common stock in their respective plan
accounts or to dispose of such stock and have the proceeds reinvested in other
investment alternatives offered under each such plan. Prior to the transfer
date, Purchaser shall, to the reasonable satisfaction of AlliedSignal's
counsel, present AlliedSignal with such evidence and information (which may
include or be provided by an opinion of Purchaser's counsel satisfactory to
AlliedSignal) as is reasonably necessary to establish that the tax-qualified
plan or plans established or to be established by Purchaser to which the
transfer or transfers described in this Section are to be made are in full
force and effect and meet all the requirements for qualification under Sections
401 and 411(d)(6) of the Code and Sellers shall, to the reasonable satisfaction
of Purchaser's counsel, present Purchaser with such evidence and information as
is reasonably necessary to establish that the Savings Plan meets the
requirements of Section 401(a) of the Code.


                                       26

         6.7 Labor Agreements. Purchaser shall assume Sellers' obligations
under the Bargaining Agreements and any applicable side letters and schedules
according to their terms as in effect of and as of the Closing Date, and shall
honor such Bargaining Agreements for the remainder of the effective term
thereof following the Closing Date.


                        ARTICLE 7. PRE-CLOSING COVENANTS

         7.1      [Intentionally left blank].

         7.2      [Intentionally left blank].

         7.3      [Intentionally left blank].

         7.4      [Intentionally left blank].

         7.5 Workers' Compensation. The Seller shall retain responsibility for
all workers' compensation events which relate to incidents occurring on or
before the Closing Date. The Purchaser shall have responsibility for all
workers' compensation events which relate to incidents occurring after the
Closing Date.

         7.6 Insurance-Primary Casualty Program. Sellers maintain at present a
series of insurance programs pursuant to which various insurance carriers have
provided and are providing insurance coverage in respect of the Business
relating to automobile liability, general liability, employers liability and
non-aircraft products liability (the "Primary Casualty Program") and Sellers
and Purchaser understand and agree that Sellers are not transferring to
Purchaser pursuant hereto any rights or interests in such Primary Casualty
Program, nor, except as otherwise set forth herein, shall Sellers be required
to maintain any of such coverages or limit in any manner Sellers' right to
change deductible levels or other terms or conditions thereof. As between
Purchaser and Sellers, however, it is agreed that the following shall apply to
claims with a date of occurrence prior to the Closing Date that are covered by
the Primary Casualty Program:

                  7.6.1 Claims Responsibility and Procedures. Purchaser shall
promptly notify in writing Sellers of any claims against the Business,
Purchaser, Sellers or any of their Affiliates arising from occurrences which
took place prior to the Closing Date relating to the Business or its prior
assets, business or operations. To the extent coverage is available under the
Primary Casualty Program, Purchaser shall handle such claims through the
applicable insurance carrier and to the limited extent required therefor is
hereby appointed as Sellers' agent in dealing with any such applicable
insurance carriers, such agency, however, being subject to revocation at any
time if Purchaser fails to comply with the provisions of this Section 7.6.
Purchaser through the applicable insurance carrier may settle any such claim on
a basis which in its judgment is reasonable provided, however, that Purchaser
agrees not to settle any such claims for an amount in excess of $50,000 without
prior consultation with AlliedSignal. Sellers and Purchasers shall cooperate
with each other in the defense of any such claims and will keep each other
informed of significant developments with respect

                                       27

<PAGE>



thereto. Neither Purchaser nor Sellers will knowingly take any action that
prejudices the other party in the collection of any applicable insurance
proceeds.

         7.7 No Inconsistent Action. Subject to Sections 9.1 and 9.2, the
parties hereto shall not take any action inconsistent with their obligations
under this Agreement or which could materially hinder or delay the consummation
of the transactions contemplated by this Agreement. None of the parties hereto
shall take or omit to take any action that could result in any of their
respective representations and warranties not being true in all material
respects on the Closing Date.

         7.8      [Intentionally left blank].

         7.9 Non-Solicitation. Sellers agree that until December 22, 1999, they
shall not, and they shall cause each of their respective Affiliates not to,
without the prior consent of Purchaser, employ or solicit for employment any
person currently employed by the Business (other than a person solicited or
hired as a result of a general solicitation (such as an advertisement) not
specifically directed to employees of the Business).

         7.10 Refunds and Remittances. In the event that Sellers or their
Affiliates receive any amount that is properly due and owing to Purchaser in
accordance with the terms of this Agreement, Sellers shall cause same to be
promptly remitted to Purchaser at the address specified in Section 13.2.

         7.11 Enforcement of Confidentiality Provisions. Sellers agree to use
reasonable best efforts to enforce, at the written request of Purchaser, (i)
the confidentiality provisions of any agreements related to the sale of the
Business (excluding any employee solicitation provisions) and (ii) all
confidentiality agreements, if any, entered into between Sellers or any of
their Affiliates and any of their employees, in each case to the extent such
provisions pertain to the Business as of the Closing Date.

         7.12 Novation of Government Contracts. As soon as reasonably
practicable following the Closing, AlliedSignal shall, in accordance with
Federal Acquisition Regulations Part 42, Section 42.12, submit in writing to
each responsible Contracting Officer (as such term is defined in Federal
Acquisition Regulations Part 42, Section 42.102(a)), a request for the U.S.
Government to (i) recognize Purchaser in accordance with this Agreement and
(ii) enter into a novation agreement (the "Novation Agreement") substantially
in the form contemplated by such regulations. AlliedSignal shall thereby
reasonably assist Purchaser in obtaining all consents, approvals and waivers
required for the purpose of processing, entering into and completing the
Novation Agreement with regard to any of the Government Contracts, including
responding to any reasonable requests for information by the U.S. Government
with regard to such Novation Agreement.

         7.13 Further Actions. Subject to the terms and conditions hereof,
Sellers and Purchaser agree to use their reasonable best efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable to consummate and make effective the
transactions contemplated by this Agreement, including without limitation,
taking all necessary or advisable action (i) in respect of the works council of
ELAC and (ii)

                                       28

<PAGE>



to terminate the profit/loss pooling arrangement (the "Pooling Arrangement")
between AS Deutschland and ELAC not later than December 31, 1998.

         7.14 Letters of Credit. Schedule 7.14 identifies letters of credit and
other similar obligations in respect of which AlliedSignal will remain as
account party ("Retained L/Cs") and other letters of credit and similar
obligations ("Assumed L/Cs") in respect of which Purchaser shall, not later
than May 31, 1998, either (a) become account party or (b) issue replacement
letters of credit, with Purchaser as account party, and obtain the cancellation
of the Assumed L/Cs and release Sellers from any obligations under any related
credit agreements. In the event that, after using its reasonable best efforts,
Purchaser cannot perform its obligations under Section 7.14(a) or (b) with
respect to the Assumed L/Cs, Purchaser shall provide back-up letters of credit
with respect to such Assumed L/Cs. Any Assumed L/C in respect of which
Purchaser has not issued a replacement or back-up letter of credit as aforesaid
by May 31, 1998 may be cancelled by AlliedSignal and Purchaser shall reimburse
AlliedSignal forthwith for all amounts drawn by the beneficiary under any such
cancelled letter of credit; provided, however, that prior to May 31, 1998,
AlliedSignal shall not waive any requirements of or agree to amend any such
Retained L/C without the prior written consent of Purchaser. The parties
acknowledge that the identity of the account party under any Retained L/C and
any Assumed L/C and other similar obligations does not alter the terms of this
Agreement, meaning, specifically and without limitation, that the provisions of
Section 3.1 (Assumed Liabilities), 3.2 (Excluded Liabilities) and Article 12
(Indemnification) are unaffected by the identity of the account party, and if a
demand for payment is made under a Retained L/C or an Assumed L/C, the
financial responsibility for the circumstances underlying such demand shall be
determined by this Agreement and not by the identity of the account party under
the letter of credit in question.

         7.15 1985 Capitalization of ELAC. AlliedSignal shall ensure that the
1985 capitalization of ELAC is confirmed by German counsel to have been lawful
and proper. The parties shall cooperate in any steps that may be necessary to
correct the capitalization, at AlliedSignal's expense.

         7.16 MCDV Subcontract. Following the Closing, AlliedSignal and
Purchaser shall use their reasonable best efforts to prepare a subcontract (the
"MCDV Subcontract") to be entered into between AlliedSignal Canada Inc. ("ASC")
and Purchaser relating to the contract between ASC and MacDonald, Dettwiler and
Associates Ltd. for the maritime coastal defense vessel, as amended (the "MCDV
Contract"). The MCDV Subcontract shall be reasonably acceptable to AlliedSignal
and Purchaser and shall transfer to Purchaser in U.S. dollars the full economic
benefit of the MCDV Contract (based on the exchange rate for U.S. and Canadian
dollars as reported in the Wall Street Journal on the date of any payment).
Purchaser shall, and AlliedSignal shall cause ASC to, enter into the MCDV
Subcontract promptly following the finalization thereof to the reasonable
satisfaction of AlliedSignal and Purchaser. In the event that (i) ASC shall be
prohibited from making any payment to Purchaser under the MCDV Subcontract,
(ii) any Canadian withholding tax would be applicable to any payment to
Purchaser by ASC under the MCDV Subcontract or (iii) ASC would lose Canadian
content credit as a result of any payment to Purchaser by ASC under the MCDV
Subcontract, AlliedSignal shall, on the date any such payment is due and in
lieu of such payment from ASC under the MCDV Subcontract, make a payment to
Purchaser in an

                                       29

<PAGE>



amount equal to the amount of the payment due under the MCDV Subcontract,
without regard to any Canadian withholding tax. Purchaser shall not have any
liability under the MCDV Subcontract for any obligation or liability relating
to the ownership or operation of the Assets or the Business on or prior to the
Closing Date relating to (a) the provision of Canadian content, (b) any penalty
or excise tax for failure to meet Canadian content obligations or (c) any
obligation for liquidated damages for failure to timely deliver.

Closing, of each of the following conditions, any one or more of which may be
waived by Sellers in their sole discretion:

                  (a) On the Closing Date, there shall be no injunction,
restraining order or decree of any nature of any court or governmental agency
or body of competent jurisdiction that is in effect that restrains or prohibits
the consummation of the transactions contemplated by this Agreement.

                  (b) The representations and warranties of Purchaser contained

                      ARTICLE 9. TERMINATION AND SURVIVAL

         9.1 Termination. Notwithstanding anything to the contrary set forth
herein, this Agreement may be terminated and the transactions contemplated
hereby abandoned at any time prior to the Closing:

                   (a) by mutual written consent of Purchaser and Sellers; or

                                       31

<PAGE>




                  (b) by Purchaser, on the one hand, or Sellers, on the other
hand, upon written notice to the other, if such other party or its Affiliate
has breached any representation, warranty or covenant contained in this
Agreement in any respect, if the non-breaching party has notified the breaching
party of the breach in writing and the breach has continued without cure for a
period of thirty (30) days after notice of the breach; or

                  (c) by the Purchaser, on the one hand, or Sellers, on the
other hand, if there shall be in effect any law or regulation that prohibits
the consummation of the Closing or if the consummation of the Closing would
violate any non-appealable final order, decree or judgment of any court or
governmental body having jurisdiction over the transactions contemplated
hereby; or

                  (d) by either party if the Closing shall not have occurred by

its obligations under this Agreement.

         9.2 Effect of Termination. If this Agreement is terminated pursuant to
Section 9.1, this Agreement shall become void and of no further force and
effect, and none of the parties hereto (nor their respective Affiliates,
directors, shareholders, officers, employees, agents, consultants,
attorneys-in-fact or other representatives) shall have any liability in respect
of such termination except that the obligations contained in Sections 9.2,
13.1, 13.3 and 13.9 shall survive; provided, however, that if such termination
is effected pursuant to Section 9.1(b) or (d) and the failure to consummate the
transactions contemplated hereby was the result of any of the conditions to
Closing having not been fulfilled by reason of the breach by either Purchaser,
on the one hand, or Sellers, on the other hand, of their respective covenants,
representations and/or warranties set forth in this Agreement or in any
agreement, document or instrument ancillary hereto, the party having so
breached shall remain liable to the other party for such breach.

         10.1   Documents to be Delivered by Sellers.  At the Closing, Sellers

Agreement.

                      ARTICLE 11. POST CLOSING OBLIGATIONS

         11.1 Further Assurances. From time to time after the Closing, without
further consideration, the parties shall cooperate with each other and shall
execute and deliver instruments of transfer or assignment, or such other
documents to the other party as such other party reasonably may request to
evidence or perfect Purchaser's right, title and interest to the Assets, and
otherwise carry out the transactions contemplated by this Agreement, including
providing that Purchaser will be able to utilize the AlliedSignal sales office
in Canada previously used by the Business. Any cash received by the Sellers
after the Closing in respect of any Asset shall be immediately remitted by
Sellers to Purchaser.

         11.2 Access to Books and Records. After the Closing, Purchaser shall
permit AlliedSignal to have reasonable access to and the right to make copies
of such of Sellers' books, records and files as constitute part of the Assets
or the ELAC Assets for any reasonable purpose at any time during regular
business hours, such as for use in litigation or financial reporting, tax
return preparation, or tax compliance matters.

         11.3 Cooperation in Litigation. The parties shall reasonably cooperate
with each other at the requesting party's expense in the prosecution or defense
of any dispute or litigation or other proceeding arising from their respective
operation of the Business, including but not limited to affording reasonable
access to and providing information regarding amounts in dispute, information
regarding former employees of the Business and documentation created in the
running of the Business relating to such dispute or litigation. Purchaser and
Sellers shall cooperate fully, as and to the extent reasonably requested by the
other party, and at their own cost and expense, in connection with the filing
of Tax Returns, the retention of records and the forwarding of any relevant
notices or other information received from any Taxing authority and any audit,
litigation or other proceeding with respect to Taxes, and shall fully and
accurately submit any tax data packages reasonably requested by Sellers within
the time periods established by the Sellers Tax department consistent with past
practices.

         11.4 Proprietary Information. Prior to the Closing Date, the Business
was routinely supplied copies of proprietary and confidential information
relating to strategic, technical, and/or marketing plans of AlliedSignal and
its Affiliates and their various operations unrelated to the Business. Although
AlliedSignal has attempted to recover such information from the Business, some
may still be present within the Business. Purchaser therefore agrees that it

                                       34

<PAGE>



will not use such information for any purpose whatsoever, and shall destroy
any remaining copies.

         11.5 Covenant Not to Compete. AlliedSignal and each of its Affiliates
agrees that for a period of five years after the Closing Date, neither it nor
any of its Affiliates will, directly or indirectly, own, manage, operate, join,
control or participate in the ownership, management, operation or control of,
any business whether in corporate, proprietorship or partnership form or
otherwise competitive with the Business as currently conducted, except for (i)
any business, service or product line acquired by AlliedSignal, directly or
indirectly, after the Closing Date to the extent the revenues attributable to
the competing business do not account for in excess of 20% of the revenues of
the business acquired or (ii) any investment by the Savings Plans or the
Pension Plans of AlliedSignal.

         11.6 Change of Name. To the extent AS Deutschland has not done so
prior to Closing, Purchaser covenants that promptly after Closing it will
change the legal name of ELAC and its wholly owned pension fund subsidiary in
accordance with German law to eliminate the reference therein to
"AlliedSignal."

         11.7 Tax Election. The Purchaser may at its option make a section 338
election with respect to the ELAC Shares or in the alternative, the Purchaser
may purchase the ELAC Shares through a German acquisition vehicle; provided
that, in either case, the Seller consents to the making of such election or
purchase which such consent shall not be unreasonably withheld.

         11.8 Research and Experimental Expenses. Sellers will furnish to the
Purchaser as soon as reasonably practicable, but in no event more than 180 days
after Closing, at Seller's cost and expense, all information reasonably
requested relating to the base period research expenses and any other
information to allow Purchaser to claim research and experimental credits in
accordance with the relevant sections of the Code and Treasury Regulations
promulgated thereunder.

         11.9 Pooling Arrangement. As described in Section 7.13, the Pooling
Arrangement is to be terminated not later than December 31, 1998.
Notwithstanding the existence of the Pooling Arrangement, any net earnings of
ELAC during the period from the Effective Date until the date the Pooling
Arrangement is terminated (the "Pooling Period") shall be treated as an Asset,
and all losses and the consequences thereof shall be treated as an Assumed
Liability, for purposes of this Agreement.


                          ARTICLE 12. INDEMNIFICATION

         12.1 Indemnification by Sellers. Sellers shall defend, indemnify and
hold harmless Purchaser and Purchaser's directors, shareholders, officers,
employees, agents, Affiliates, successors and each of the heirs, executors and
successors and assigns of any of the foregoing (collectively, the "Purchaser
Indemnified Parties") from and against any and all claims, liabilities,
obligations, losses, costs, expenses (including, without limitation, reasonable
legal,

                                       35

<PAGE>



accounting and similar fees and expenses), fines, damages (individually a
"Loss" and collectively "Losses"), arising out of:

                  (a) any breach or violation of any of the covenants or
agreements made by Sellers in this Agreement or the Other Agreements;

                 (b) any breach of, or any inaccuracy or misrepresentation in,
any of the representation or warranties made by Sellers in this Agreement or in
any Schedule, agreement, instrument, certificate or similar document required
to be delivered pursuant to the terms hereof; or

                  (c) any of the Excluded Liabilities or Excluded Assets.

         12.2 Tax Indemnification. The Sellers shall, jointly and severally, be
responsible for, shall pay or cause to be paid, and shall indemnify and hold
harmless the Purchaser Indemnified Parties from and against any and all Taxes
for or in respect of each of the following:

                  (a) any and all Taxes with respect to any taxable period or a
portion thereof, of ELAC (or any predecessor) ending on or before the Closing
Date;

                  (b) with respect to any and all Taxes of any member of a
consolidated, combined or unitary group of which ELAC (or any predecessor) is
or was a member on or prior to the Closing Date by reason of the liability of
ELAC 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;

                  (c) any Taxes arising out of a breach of the representations
and warranties contained in Section 4.16; and

                  (d) 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), including but not limited to the profit/loss pooling
arrangement with AS Deutschland set forth on Schedule 4.16, to which ELAC was
obligated, or was a party, on or prior to the Closing Date.

         12.3 Indemnification by Purchaser. Purchaser shall indemnify and hold
harmless AlliedSignal and AlliedSignal's directors, shareholders, officers,
employees, agents, consultants, representatives, Affiliates, successors and
assigns (the "AlliedSignal Indemnified Parties") from and against any and all
Losses arising out of:

                  (a) any breach or violation by Purchaser of any of the
covenants or agreements made by Purchaser in this Agreement or the Other
Agreements;

                  (b) any breach of, or any inaccuracy in any of the
representations or warranties made by Purchaser in this Agreement, or in any
Schedule, agreement, certificate, instrument or similar documents required to
be delivered pursuant to the terms hereof; or


                                       36

<PAGE>



                  (c) any Assumed Liability.

         12.4 Indemnification Procedure. (a) Any party seeking indemnification
hereunder (the "Indemnitee") shall notify the party liable for such
indemnification (the "Indemnitor") in writing of any event, omission or
occurrence which the Indemnitee believes has given or could give rise to Losses
which are indemnifiable hereunder (such written notice being hereinafter
referred to as a "Notice of Claim"). Any Notice of Claim shall be given
promptly after the Indemnitee becomes aware of such event, omission or
occurrence; provided, that the failure of any Indemnitee to give notice as
provided in this Section 12.4 shall not relieve the Indemnitor of its
obligations under this Section 12.4, except to the extent that the Indemnitor
is actually prejudiced by such failure to give notice. A Notice of Claim shall
specify in reasonable detail the nature and the particulars of the event,
omission or occurrence giving rise to a right of indemnification to the extent
known by or available to Indemnitee. The Indemnitor shall satisfy its
obligations hereunder within thirty (30) days of its receipt of a Notice of
Claim.

                  (b) All costs and expenses incurred by the Indemnitor in
defending any claim or demand shall be a liability of, and shall be paid by,
the Indemnitor. Except as hereinafter provided, in the event that the
Indemnitor notifies the Indemnitee within the 30 day period that it desires to
defend the Indemnitee against such claim or demand, the Indemnitor shall be
deemed to waive its right to contest such Indemnitee's right to indemnification
hereunder and shall have the right to defend the Indemnitee by appropriate
proceedings and shall have the sole power to direct and control such defense.
If any Indemnitee desires to participate in any such defense, it may do so at
its sole cost and expense; provided, that such Indemnitee shall have the right
to employ separate counsel to represent such Indemnitee in such defense, at the
Indemnitor's expense, if (i) in such Indemnitee's reasonable judgement and on
the advice of counsel, a conflict of interest between such Indemnitor and such
Indemnitee exists with respect to such claim or demand or (ii) the Indemnitor
agrees to the retention of such counsel. So long as the Indemnitor is
reasonably contesting any such claim or demand in good faith, the Indemnitee
shall not pay or settle a claim or demand without the consent of the Indemnitor
(unless the Indemnitee waives in writing any right to indemnity therefor). The
Indemnitor may settle any claim or demand without the consent of the Indemnitee
provided that such settlement includes a full, unconditional and complete
release of the Indemnitee, and provided also that no such settlement will,
without the prior written consent of the Indemnitee, impose any obligation or
restriction on the Indemnitee or any of its assets or businesses. So long as
the Indemnitor is defending in good faith any such third party claim, demand,
suit, action or proceeding, the Indemnitee shall at all times cooperate in all
reasonable ways with, make its relevant files and records available for
inspection and copying by, and make its employees available or otherwise render
reasonable assistance to, the Indemnitor and shall be reimbursed for its
reasonable out-of-pocket expenses related thereto. In the event that the
Indemnitor fails to timely defend, contest or otherwise protect against any
such third party claim, demand, suit, action or proceeding, the Indemnitee at
the Indemnitor's expense shall have the right, but not the obligation, to
defend, contest, assert crossclaims or counterclaims, or otherwise protect
against, the same and may make any compromise or settlement thereof and be
entitled to all amounts paid as a result of such third party claim, demand,
suit or action or any compromise or settlement thereof.

<PAGE>




                  (c) The Indemnitor, following receipt of any notice from any
Indemnitee requesting reimbursement for a Loss (which notice documents in
reasonable detail the Loss or portion thereof by the Indemnitee) shall promptly
and in any case within thirty days of receipt provide such reimbursement,
unless and only to the extent that the Indemnitor disputes in good faith its
indemnity obligation with respect to such Loss.

                  (d) Each Indemnitee shall reasonably cooperate in complying
with any applicable foreign, federal, state or local laws, rules or regulations
or any discovery or testimony necessary to effectively carry out the
Indemnitor's obligations hereunder. Such Indemnitee shall be reimbursed for any
reasonable out-of-pocket expenses incurred in connection with such compliance.

         12.5 Survival and Limitations. Except as otherwise provided herein,
the warranties and representations of the parties contained in this Agreement
or in any instrument delivered pursuant hereto, as deemed to have been given as
of the Effective Date or the Closing Date, as the case may be, pursuant to
Section 8.1(b), will survive the Closing Date and will remain in full force and
effect thereafter for a period of two years from the Closing Date; provided
that the representations and warranties contained in (i) Sections 4.8 and 4.18
shall survive the Closing Date indefinitely and (ii) Sections 4.3, 4.10, 4.11,
4.16 and 4.21 which shall survive the Closing Date until 90 days following the
expiration of any statute of limitations (or extensions thereof) applicable to
the matters described therein; and provided further that in the event notice of
any claim for indemnification is given within the applicable survival period,
the representations and warranties that are the subject of such indemnification
claim shall survive until such time as such claim is finally resolved. Anything
to the contrary contained herein notwithstanding, (a) neither party shall
assert any claim against the other for indemnification (not including
indemnification for Taxes) hereunder with respect to any inaccuracy or breach
of such warranties or representations unless and until the amount of such claim
or claims, including any claims deemed made pursuant to Section 12.8, shall
exceed $750,000 calculated on a cumulative basis and not a per item basis, and
then only in respect to the excess over said $750,000; and (b) neither party
shall be entitled to recover from the other more than 50% of the sum of (I) the
Purchase Price hereunder and (II) the Purchase Price under the Facility Sale
Agreement with respect to all claims for indemnity with respect to any
inaccuracy or breach of such warranties or representations.

         12.6 Adjustment for Insurance and Taxes. The amount (an "Indemnity
Payment") which an Indemnitor is required to pay on behalf of any Indemnitee
pursuant to this Article 12 shall be reduced by the amount of any insurance
proceeds theretofore or thereafter actually received by or on behalf of the
Indemnitee in reduction of the related indemnifiable loss. An Indemnitee which
shall have received or on behalf of which there shall be paid an Indemnity
Payment and which shall subsequently receive, directly or indirectly, insurance
proceeds in respect of the related indemnifiable loss, shall pay to the
Indemnitor the amount of such insurance proceeds or, if lesser, the amount of
the Indemnity Payment. Where any tax benefit is available to the Indemnitee
with respect to an indemnifiable event, the indemnity payment shall be reduced
dollar for dollar by the amount of such tax benefit and where any net Tax cost
is incurred by the Indemnitee arising from the receipt of indemnity payments
hereunder, the indemnity payment shall be increased dollar for dollar by the
amount of such Tax cost (grossed up for such increase), provided that such Tax
benefit or Tax cost shall be computed

                                       38

<PAGE>



at the highest federal, state, local and foreign corporate income tax rate of
the jurisdiction in which such Tax benefit or Tax cost so relates.

         12.7 Environmental Liabilities. (a) To the fullest extent permitted
under (i) the Stock Purchase Agreement pursuant to which AlliedSignal acquired
ELAC from Honeywell and (ii) Applicable Law, AlliedSignal agrees to assign its
indemnification rights if any in respect of the ELAC facility to Purchaser and
to the extent not assignable to enforce such provisions for the benefit of
Purchaser and to provide any amounts it receives in connection therewith to
Purchaser.

                  (b) Notwithstanding Section 3.2(d), (i) Purchaser shall
indemnify the AlliedSignal Indemnified Parties from and against the first $3
million of Losses, in aggregate, in respect of the combined Environmental
Liabilities hereunder and under the Facility Sale Agreement and 50% of the next
$2 million of such Losses and (ii) AlliedSignal shall indemnify the Purchaser
Indemnified Parties from and against any other Losses relating to Environmental
Liabilities.

         12.8 Facility Sale Agreement. Purchaser agrees to indemnify the Allied
Signal Indemnified Parties from and against amounts up to $750,000, calculated
on a cumulative basis and not a per item basis, paid by Sellers under Article
11 of the Facility Sale Agreement for claims under the Facility Sale Agreement
for indemnification (not including indemnification for Taxes) thereunder with
respect to any inaccuracy or breach of the warranties or representations
thereunder. If AlliedSignal shall be liable to any party pursuant to the
Facility Sale Agreement (a "Facility Sale Liability"), Purchaser shall
indemnify AlliedSignal to the extent the amount of such Facility Sale Liability
exceeds the amount for which Sellers would have been liable under this
Agreement had the Real Estate Assets (as defined in the Facility Sale
Agreement) been included in the Assets. Any payments made pursuant to this
Section 12.8 shall be deemed "claims" for purposes of the $750,000 threshold
set forth in Section 12.5. Sellers shall not be required to pay more than once
in respect of any Loss.


                           ARTICLE 13. MISCELLANEOUS

         13.1 Expenses. Except as specifically set forth elsewhere herein and
except that a party not in breach of this Agreement shall be entitled to
recover from a breaching party all expenses and costs incurred by the
non-breaching party by reason of such breach (including, without limitation all
legal expenses and costs), each of the parties hereto shall pay its own
expenses and costs incurred or to be incurred by it in negotiating, closing and
carrying out this Agreement, and, in no event, shall any such fees and expenses
of the Sellers constitute "Assumed Liabilities" under this Agreement.

         13.2 Notices. Any notice or communication given pursuant to this
Agreement by a party hereto to the other party shall be in writing and hand
delivered, or mailed by registered or certified mail, postage prepaid, return

sent via facsimile, with an original mailed as follows:

         13.3 Confidentiality. AlliedSignal and Purchaser have entered into a
Confidentiality Agreement dated September 23, 1997 which notwithstanding any
provision herein to the contrary shall survive the execution and delivery of
this Agreement and the Closing hereunder.

Business and has asserted certain claims with respect to the December
Agreement, relating, inter alia, to the financial position and business
prospects of the Business. The parties have resolved all such claims and, for
good and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, have restated their agreement with respect to the purchase and
sale of the Business, as set forth in this Agreement. The December Agreement is
hereby terminated, is

                                       40

<PAGE>



of no further force or effect, and no party shall have any right or obligation,
whether as a matter of the law of contract or otherwise, under, arising out of
or relating to, the December Agreement or any matter appearing in the December
Agreement that does not appear in this Agreement (including, without
limitation, the representations and warranties of Sellers that do not appear in
this Agreement). The agreement between the parties as to the purchase and sale
of the Business is expressed in its entirety in this Agreement.

         13.6 Construction. When the context so requires, references herein to

masculine or neuter gender include the feminine. The headings contained in this
Agreement and the tables of contents, exhibits and schedules are for reference

         13.7 Assignment. This Agreement may not be assigned, in whole or in
part, by any party hereto without the prior written consent of the other
parties hereto, which consent shall not unreasonably be withheld; provided that
Purchaser may, without the consent of Sellers, assign its rights and
obligations, in whole or in part, to any wholly-owned subsidiary of Purchaser
so long as Purchaser remains bound by all the terms of this Agreement.

         13.8 Amendment. This Agreement may be amended, supplemented or
otherwise modified only by written agreement duly executed by the parties
hereto.

         13.9 Applicable Law. This Agreement shall be construed in accordance

writing. Except as provided in the preceding sentence, no action taken pursuant
to this Agreement, including, without limitation, any investigation by or on
behalf of any party, shall be deemed to constitute a waiver by the party taking
such action of compliance with any representations, warranties, covenants or
agreements contained herein, or in any documents delivered or to be delivered
pursuant to this Agreement or in connection with the Closing hereunder. A
waiver of any breach or failure to enforce any of the terms or conditions of
this Agreement shall not

                                       41

<PAGE>



in any way affect, limit or waive any party's rights at any time to enforce

with the provisions of the bulk sales law of any jurisdiction. The Sellers
agree to indemnify and hold harmless Purchaser from and against any and all
liabilities which may be asserted by third parties against Purchaser as a
result of such noncompliance.

                      1997 OPTION PLAN FOR KEY EMPLOYEES
                      NONQUALIFIED STOCK OPTION AGREEMENT




                  THIS AGREEMENT, effective as of the 1st day of July, 1997
(the Grant Date"), between L-3 Communications Holdings, Inc., a Delaware
corporation (the "Company"), and                         (the "Optionee").

                  WHEREAS, the Company has adopted the 1997 Option Plan for
Key Employees of L-3 Communications Holdings, Inc. (the "Plan") in order to
provide additional incentive to selected officers and employees of the Company
and its subsidiaries; and

                  WHEREAS, the Committee responsible for administration of the
Plan has determined to grant an option to the Optionee as provided herein and
the Company and the Optionee hereby wish to memorialize the terms and
conditions applicable to the Option (as defined below);


                  NOW, THEREFORE, the parties hereto agree as follows:

1.       Grant of Option.

                           1.1      Effective as of the Grant Date, for good
and valuable consideration, the Company hereby irrevocably grants to the
Optionee the right and option (the "Option") to purchase all or any part of an
aggregate of         shares (the "Shares") of the Company's Class A Common
Stock, par value $0.01 per share, subject to, and in accordance with, the
terms and conditions set forth in this Option Agreement.

                           1.2      The Option is not intended to qualify as
an Incentive Stock Option within the meaning of Section 422 of the Code.

                           1.3      This Option Agreement shall be construed
in accordance and consistent with, and subject to, the terms of the Plan (the
provisions of which are incorporated hereby by reference); and, except as
otherwise expressly set forth herein, the capitalized terms used in this
Option Agreement shall have the same definitions as set forth in the Plan.

2.       Exercise Price.

                  The price at which the Optionee shall be entitled to
purchase the Shares upon the exercise of the Option shall be $6.47 per Share
subject to adjustment as provided in Section 9, without commission or other
charge.

3.       Duration of Option.

                  The Option shall be exercisable to the extent and in the
manner provided herein for a period of ten (10) years from the Grant Date (the
"Exercise Term"); provided, however, that the Option may be earlier terminated
as provided in Section 6 hereof.


<PAGE>





4.       Exercisability of Option.

                  Unless otherwise provided in this Option Agreement or the
Plan, the Option shall entitle the Optionee to purchase, in whole at any time
or in part from time to time, 20% of the total number of shares covered by the
Option on the business day following the first anniversary of the Grant Date,
an additional 50% of the total number of Shares covered by the Option on the
second anniversary of the Grant Date and the final 30% of the total number of
Shares covered by the Option after the expiration of the third anniversary of
the Grant Date; provided that, if the initial public offering (the "IPO") of
the Company's stock pursuant to an effective registration statement (other
than a registration statement on S-8 or any similar or successor form) filed
under the Securities Act of 1933 (the "Securities Act") shall be completed
prior to the second anniversary of the Grant Date, 15% of the total number of
shares covered by the Option (which would otherwise become excercisable on the
second anniversary of the Grant Date) will become excercisable on the later of
(i) the date of completion of the IPO and (ii) the business day following the
first anniversary of the Grant Date, and the shares that become excercisable
on the second anniversary of the Grant Date shall be reduced to 35% of the
total number of shares covered by the Option. Each such right of purchase
shall be cumulative and shall continue, unless sooner exercised or terminated
as herein provided, during the remaining period of the Exercise Term. Any
fractional number of shares resulting from the application of the foregoing
percentages shall be rounded to the next higher whole number of Shares (not to
exceed the total number of Shares granted as provided in Section 1.1).

5.       Manner of Exercise and Payment.

                  5.1 Subject to the terms and conditions of this Option
Agreement and the Plan, the Option may be exercised by delivery of written
notice to the Secretary of the Company, at its principal executive office.
Such notice shall state that the Optionee or other authorized person is
electing to exercise the Option and the number of Shares in respect of which
the Option is being exercised and shall be signed by the person or persons
exercising the Option. Any exercisable portion of the Option or the entire
Option, if then wholly exercisable, may be exercised in whole or in part,
provided that partial exercise shall be for whole shares of Class A Common
Stock only. If requested by the Committee, such person or persons shall (i)
deliver this Agreement to the Secretary of the Company who shall endorse
thereon a notation of such exercise and (ii) provide satisfactory proof as to
the right of such person or persons to exercise the Option.

                  5.2 The notice of exercise described in Section 5.1 shall be
accompanied by (x) either (i) payment of the full purchase price for the
Shares in respect of which the Option is being exercised, in cash, by check or
a combination thereof or (ii) subject to the consent of the Committee,
instructions from the Optionee to the Company directing the Company to deliver
a specified number of Shares directly to a designated broker or dealer
pursuant to a cashless exercise election which is made in accordance with such
requirements and procedures as are acceptable to the Committee in its sole
discretion and (y) full payment of all applicable Withholding Taxes (as
defined in Section 11) pursuant to Section 11 hereof.

                  5.3 Upon receipt of the notice of exercise and any payment
or other documentation as may be necessary pursuant to Section 5.2 relating to
the Shares in respect of which the Option is being exercised, the Company
shall, subject to the Plan and this Option Agreement, take such action as may
be necessary to effect the transfer to the Optionee of the number of Shares as
to which such exercise was effective.

                                     -2-
<PAGE>





                  5.4 The Optionee shall not be deemed to be the holder of, or
to have any of the rights and privileges of a stockholder of the Company in
respect of, Shares purchased upon exercise of the Option until (i) the Option
shall have been exercised pursuant to the terms of this Option Agreement and
the Optionee shall have paid the full purchase price for the number of Shares
in respect of which the Option was exercised and any applicable Withholding
Taxes and (ii) the Company shall have issued certificates representing such
Shares to the Optionee.

6.       Termination of Employment.

                  6.1 If, prior to the date of the initial vesting of the
Option pursuant to Section 4 hereof (the "Initial Vesting Date"), the
Optionee's employment with the Company shall be terminated for any reason, the
Optionee's right to exercise the Option shall terminate as of the effective
date of termination (the "Termination Date") and all rights hereunder shall
cease.

                  6.2 If, on or after the Initial Vesting Date, the Optionee's
employment with the Company shall be terminated for any reason other than
death, permanent disability or for Cause, the Optionee shall have the right
within three months after the Termination Date to exercise the Option to the
extent that installments thereof shall have accrued at the Termination Date
and shall not have been exercised, subject to any other limitation contained
herein on the exercise of the Option in effect at the date of exercise. If the
Optionee's employment is terminated for Cause, the Option shall terminate as
of the Termination Date, whether or not exercisable. For purposes hereof,
"Cause" means the Optionee's (i) intentional failure to perform reasonably
assigned duties, (ii) dishonesty or willful misconduct in the performance of
duties, (iii) engaging in a transaction in connection with the performance of
duties to the Company which transaction is adverse to the interests of the
Company and is engaged in for personal profit or (iv) willful violation of any
law, rule or regulation in connection with the performance of duties (other
than traffic violations or similar offenses).

                  6.3 If the Optionee shall die within the three-month period
referred to in 6.2 above, or shall die or become permanently disabled while in
the employ of the Company on or after the Initial Vesting Date, the Optionee
or the executor or administrator of the estate of the Optionee or the person
or persons to whom the Option shall have been validly transferred by the
executor or administrator pursuant to will or the laws of descent and
distribution shall have the right, within one year from the date of the
Optionee's death or permanent disability, to exercise the Option to the extent
that the Option was exercisable at the date of death, subject to any other
limitation contained herein on the exercise of the Option in effect at the
date of exercise.

                  6.4 Whether employment has been terminated and the
determination of the Termination Date for the purposes of this Agreement shall
be determined by the Committee whose good faith determination shall be final,
binding and conclusive. If the IPO is not completed before the Initial Vesting
Date, the Company reserves the right, prior to the completion of the IPO, to
modify the provisions governing the rights of the Optionee upon termination of
employment to provide the Company with an option to repurchase any Shares
purchased pursuant to this Option Agreement and to terminate any vested
portion of the Option for a cash payment equal to the fair market value of
such Shares or the Shares represented by the vested portion of the Option
(less, for the Shares represented by the vested portion of Option, the
aggregate exercise price for such Shares) and such modification shall be
binding on the Optionee.

                                     -3-
<PAGE>





7.       Nontransferability.

                  The Option shall not be transferable other than by will or
by the laws of descent and distribution or by such other means explicitly
permitted pursuant to Rule 16b-3 under the Exchange Act. During the lifetime
of the Optionee, the Option shall be exercisable only by the Optionee. After
the death of the Optionee, any exercisable portion of the Option may, prior to
the time when the Option becomes unexercisable under Section 6.3, be exercised
by the Optionee's personal representative or by any person empowered to do so
under the Optionee's will or under the then applicable laws of descent and
distribution.

8.       No Right to Continued Employment.

                  Nothing in this Option Agreement or the Plan shall be
interpreted or construed to confer upon the Optionee any right to continue
employment by the Company or any of its subsidiaries, nor shall this Agreement
or the Plan interfere in any way with the right of the Company or any of its
subsidiaries to terminate the Optionee's employment at any time for any reason
whatsoever, whether or not with Cause.

9.       Adjustments.

                  In the event that the outstanding shares of the Class A
Common Stock are, from time to time, changed into or exchanged for a different
number or kind of shares of the capital stock of the Company or other
securities of the Company by reason of a merger, consolidation,
recapitalization, reclassification, stock split, stock dividend, combination
of capital stock, or other similar increase or decrease in the number of
shares outstanding without receiving compensation therefor, the Committee
shall make an appropriate and equitable adjustment in the number and kind of
Shares or other consideration as to which such Option, or portions thereof
then unexercised, shall be exercisable and the exercise price therefor. Any
such adjustment made by the Committee shall be final, binding and conclusive
upon the Optionee, the Company and all other interested persons. Any such
adjustment may provide for the elimination of any fractional share which might
otherwise become subject to the Option.

10.      Effect of a Change in Control.

                  10.1 Notwithstanding anything contained in the Plan or this
Agreement to the contrary, in the event of a Change in Control, (a) the Option
becomes immediately fully exercisable as to 100% of the Shares subject to the
Option, and (b) upon termination of an Optionee's employment with the Company,
following a Change in Control, the Option shall remain exercisable until one
year after termination, but in no event beyond the Exercise Term. In the case
of a Change in Control which is intended to be treated as a "pooling of
interests" under generally accepted accounting principals (a "Pooling
Transaction"), the Board of Directors may take such actions which it
determines after consultation with its advisors that are reasonably necessary
in order to assure that the Pooling Transaction will qualify as such. The
Company reserves the right to change or modify in any way the definition of
Change of Control set forth in this Option Agreement and any such change or
modification shall be binding on the Optionee.

                  10.2     For the purposes of this Option Agreement, "Change
in Control shall mean the first to occur of the following:

                  a.  The acquisition by any person or group (including a
                      group within the meaning of Section 13(d)(3) or 14(d)(2)
                      of the Exchange Act), other than the Company or any of
                      its subsidiaries, of beneficial ownership (within the
                      meaning of Rule 13d-3 promulgated under the Exchange
                      Act) of 51% or more of the combined voting power of the
                      Company's then outstanding voting securities, other than
                      (i) pursuant to a transfer by Lehman Brothers Capital
                      Partners III, L.P. to any of its affiliates or (ii) by
                      any employee benefit plan maintained by the Company;

                  b.  The sale of all or substantially all the assets of the
                      Company or its subsidiaries; or

                  c.  The election, including the filling of vacancies, during
                      any period of 24 months or less, of 50% or more, of the
                      members of the Board of Directors, without the approval
                      of Continuing Directors, as constituted at the beginning
                      of such period. "Continuing Directors" shall mean any

                      the Board of Directors on July 1, 1997, or (ii) is
                      nominated for election to the Board of Directors by a
                      majority of the Board which is comprised of directors
                      who were, at the time of such nomination, Continuing
                      Directors.

11.      Withholding of Taxes.

                  The Company shall have the right to deduct from any
distribution of cash to the Optionee an amount equal to the federal, state and
local income taxes and other amounts as may be required by law to be withheld
(the "Withholding Taxes") with respect to the Option. The Optionee shall pay
the Withholding Taxes to the Company in cash prior to the issuance of the
Shares. In satisfaction of the Withholding Taxes, the Optionee may make a
written election (the "Tax Election"), which may be accepted or rejected in
the discretion of the Committee, to have withheld a portion of the Shares
issuable to him or her upon exercise of the Option. For withholding tax
purposes, the Shares should be valued on the date the withholding obligation
is incurred, provided that to the extent applicable, such election is made in
accordance with Rule 16b-3(e) of the Act.

12.      Optionee bound by the Plan.

                  The Optionee hereby acknowledges receipt of a copy of the
Plan and agrees to be bound by all the terms and provisions thereof.

13.      Modification of Agreement.

                  This Agreement may be modified, amended, suspended or
terminated, and any terms or conditions may be waived, but, subject to
paragraphs 6.4 and 10.1, only by a written instrument executed by the parties
hereto.

14.      Severability.

                  Should any provision of this Agreement be held by a court of
competent jurisdiction to be unenforceable or invalid for any reason, the
remaining provisions of this Agreement shall not be affected by such holding
and shall continue in full force in accordance with their terms.

                  (b) The Optionee acknowledges and understands that the

subsequently registered under the Securities Act or an exemption from such
registration is available. The Optionee further acknowledges and understands
that the Company is under no obligation to register the Shares. The Optionee
understands that (x) the transfer of the Shares will be restricted pursuant to
the terms of paragraph 20 of this Option Agreement and (y) the certificate
evidencing the Shares will be imprinted with a legend which prohibits the

registration is not required in the opinion of counsel satisfactory to the
Company.

1.        Purpose of Plan

         The 1997 Option Plan for Key Employees of L-3 Communications

         (a) to promote the long term financial interests and growth of L-3
Communications Holdings, Inc. (the "Corporation") and its subsidiaries by
attracting and retaining management personnel with the training, experience
and ability to enable them to make a substantial contribution to the success
of the Corporation's business;

         (b) to motivate management personnel by means of growth-related
incentives to achieve long range goals; and

2.        Definitions

         As used in the Plan, the following words shall have the following

<PAGE>

         (i)   "Option"  means an option to purchase shares of the Common

         (k) "Subsidiary" shall mean any corporation in an unbroken chain of
corporations beginning with the Corporation if each of the corporations, or

in such chain.

3.        Administration of Plan

         (a) The Plan shall be administered by the Committee. None of the
members of the Committee shall be eligible to be selected for Option grants
under the Plan, or have been so eligible for selection within one year prior
thereto; provided, however, that the members of the Committee shall qualify to
administer the Plan for purposes of Rule 16b-3 (and any other applicable rule)
promulgated under Section 16(b) of the Exchange Act to the extent that the
Corporation is subject to such rule. The Committee may adopt its own rules of
procedure, and action of a majority of the members of the Committee taken at a
meeting, or action taken without a meeting by unanimous written consent, shall
constitute action by the Committee. The Committee shall have the power and
authority to administer, construe and interpret the Plan, to make rules for
carrying it out and to make changes in such rules. Any such interpretations,
rules and administration shall be consistent with the basic purposes of the
Plan.

         (b) The Committee may delegate to the Chief Executive Officer and to
other senior officers of the Corporation its duties under the Plan subject to
such conditions and limitations as the Committee shall prescribe except that
only the Committee may designate and make Option grants to Participants who
are subject to Section 16 of the Exchange Act.

         (c) The Committee may employ attorneys, consultants, accountants,
appraisers, brokers or other persons. The Committee, the Corporation, and the
officers and directors of the Corporation shall be entitled to reply upon the
advice, opinions or valuations of any such persons. All actions taken and all
interpretations and determinations made by the Committee in good faith shall
be final and binding upon all Participants, the Corporation and all other
interested persons. No member of the Committee shall be personally liable for
any action, determination or interpretation made in good faith with respect to
the Plan or Option grants, and all members of the Committee shall be fully
protected by the Corporation with respect to any such action, determination or
interpretation.

4.        Eligibility

         The Committee may from time to time make Option grants under the Plan
to such Employees, or other persons having a relationship with the Corporation
or any of its Subsidiaries, and in such form and having such terms, conditions
and limitations as the Committee may determine. No Option grants may be made
under this Plan to non-employee directors of the Corporation or any of its
Subsidiaries. Options may be granted singly, in combination or in tandem. The
terms, conditions and limitations of each Option grant under the Plan shall be
set forth in an Option Agreement, in a form approved by the Committee,
consistent, however, with the terms of the Plan; provided, however, that such
Option Agreement shall contain provisions dealing with the treatment of Option
grants in the event of the termination, death or disability of a Participant,
and may also include provisions concerning the treatment of Option grants in
the event of a change of control of the Corporation.

5.        Grants

         From time to time, the Committee, in its sole discretion, will
determine the forms and amounts of Options to be granted to Participants. At
the time of the grant the Committee shall determine, and shall include in the
Option Agreement or other Plan rules, the option exercise period, the option
price and such other conditions or restrictions on the grant or exercise of
the Option as the Committee deems appropriate. In addition to other
restrictions contained in the Plan, an Option granted under this Paragraph 5,
may not be exercised more than 10 years after the date it is granted. Payment
of the option price shall be made in cash or in shares of Common Stock, or a
combination thereof, in accordance with the terms of the Plan, the Option
Agreement and of any applicable guidelines of the Committee in effect at the
time.

         Options may be granted prior to the effective date of the Plan (as
determined pursuant to Paragraph 13 herein); provided, however, that no Option
shall be exercisable prior to the date of the approval of the Plan by the
stockholders of the Corporation.

6.        Limitations and Conditions

         (a) The number of Shares available under this Plan shall be 3,255,815
shares of the authorized Common Stock as of the effective date of the Plan.
Unless restricted by applicable law, Shares related to Options that are
forfeited, terminated, cancelled or expire unexercised, shall immediately
become available to be subject to Option grants.

         (b) No Options shall be granted under the Plan beyond ten years after
the effective date of the Plan, but the terms of Options granted on or before
the expiration of the Plan may extend beyond such expiration. At the time an
Option is granted or amended or the terms or conditions of an Option are
changed, the Committee may provide for limitations or conditions on such
Grant.

         (c) Nothing contained herein shall affect the right of the
Corporation to terminate any participant's employment at any time or for any
reason.

         (d) Other than as specifically provided with regard to the death of a
Participant, no benefit under the Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or
charge, and any attempt to do so shall be void. No such benefit shall, prior
to receipt thereof by the Participant, be in any manner liable for or subject
to the debts, contracts, liabilities, engagements, or torts of the
Participant.

         (e) Participants shall not be, and shall not have any of the rights
or privileges of, stockholders of the Corporation in respect of any Shares
purchasable in connection with any Option grant unless and until certificates
representing any such Shares have been issued by the Corporation to such
Participants.

         (f) No election as to benefits or exercise of Options may be made
during a Participant's lifetime by anyone other than the Participant except by
legal representative appointed for or by the Participant.

         (g) Absent express provisions to the contrary, any grant of Options
under this Plan shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Corporation or its
Subsidiaries and shall not affect any benefits under any other benefit plan of
any kind now or subsequently in effect under which the availability or amount
of benefits is related to level of compensation. This Plan is not a
"Retirement Plan" or "Welfare Plan" under the Employee Retirement Income
Security Act of 1974, as amended.

         (h) Unless the Committee determines otherwise, no benefit or promise
under the Plan shall be secured by any specific assets of the Corporation or
any of its Subsidiaries, nor shall any assets of the






                                      3
<PAGE>


Corporation or any of its Subsidiaries be designated as attributable or
allocated to the satisfaction of the Corporation's obligations under the Plan.

7.        Transfers and Leaves of Absence

         For purposes of the Plan, unless the Committee determines otherwise:
(a) a transfer of a Participant's employment without an intervening period of
separation among the Corporation and any Subsidiary shall not be deemed a
termination of employment, and (b) a Participant who is granted in writing a
leave of absence shall be deemed to have remained in the employ of the
Corporation during such leave of absence.

8.        Adjustments

         In the event of any change in the outstanding Common Stock by reason
of a stock split, spin-off, stock dividend, stock combination or
reclassification, recapitalization or merger, change of control, or similar
event, the Committee shall adjust appropriately and equitably the number of
Shares subject to the Plan and available for or covered by Option grants and
exercise prices related to outstanding Option grants and make such other
revisions to outstanding Option grants as it deems are equitably required.

9.        Merger, Consolidation, Exchange, Acquisition, Liquidation or
          Dissolution

         In its absolute discretion, and on such terms and conditions as it
deems appropriate, coincident with or after the grant of any Option, the
Committee may provide that such Option cannot be exercised after the merger or
consolidation of the Corporation into another corporation, the exchange of all
or substantially all of the assets of the Corporation for the securities of
another corporation, the acquisition by another corporation of 80% or more of
the Corporation's then outstanding shares of voting stock or the
recapitalization, reclassification, liquidation or dissolution of the
Corporation, and if the Committee so provides, it shall also provide, either
by the terms of such Option or by a resolution adopted prior to the occurrence
of such merger, consolidation, exchange, acquisition, recapitalization,
reclassification, liquidation or dissolution, that, for a period of at least
thirty (30) days prior to such event, such Option shall be exercisable as to
all shares subject thereto, notwithstanding anything to the contrary herein
(but subject to the provisions of Paragraph 6(b) and that, upon the occurrence
of such event, such Option shall terminate and be of no further force or
effect; provided, however, that the Committee may also provide, in its
absolute discretion, that even if the Option shall remain exercisable after
any such event, from and after such event, any such Option shall be
exercisable only for the kind and amount of securities and/or other property,
or the cash equivalent thereof, receivable as a result of such event by the
holder of a number of shares of stock for which such Option could have been
exercised immediately prior to such event.

10.       Amendment and Termination

         The Committee shall have the authority to make such amendments to any
terms and conditions applicable to outstanding Option grants as are
consistent with this Plan provided that, except for adjustments under
Paragraph 8 or 9 hereof, no such action shall modify such Option grant in a
manner adverse to the Participant without the Participant's consent.

         The Board of Directors may amend, suspend or terminate the Plan
except that no such action, other than an action under Paragraph 8 or 9
hereof, may be taken which would, without shareholder approval, increase the
aggregate number of Shares subject to Options under the Plan, decrease the
exercise price of outstanding Options, change the requirements relating to the
Committee or extend the term of the Plan, but only to the extent such
shareholder approval would be required by Rule 16b-3 at a time when the
Company is subject to Section 16(b) of the Exchange Act.

11.       Foreign Options and Rights

         The Committee may grant Options to Employees who are subject to the
laws of nations other than the United States, which Option grants may have
terms and conditions that differ from the terms thereof as provided elsewhere
in the Plan for the purpose of complying with foreign laws.

12.       Withholding Taxes

         The Corporation shall have the right to deduct from any cash payment
made under the Plan any federal, state or local income or other taxes required
by law to be withheld with respect to such payment. It shall be a condition to
the obligation of the Corporation to deliver shares upon the exercise of an
Option that the Participant pay to the Corporation such amount as may be
requested by the Corporation for the purpose of satisfying any liability for
such withholding taxes. Any Option Agreement may provide that the Participant
may elect, in accordance with any conditions set forth in such Option
Agreement, to pay a portion or all of such withholding taxes in shares of
Common Stock.

13.       Effective Date and Termination Dates

         The Plan shall be effective on and as of the date of its approval by
the stockholders of the Corporation and shall terminate ten years later,
subject to earlier termination by the Board of Directors pursuant to Paragraph
10.
